General Investment Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the Balanced,
 Growth and Income, CORE Large Cap Value, CORE Large Cap Growth, CORE Small
 Cap Equity, Strategic Growth, Growth Opportunities, Mid Cap Value, Small Cap
 Value and Real Estate Securities Funds. Goldman Sachs Funds Management, L.P.
 serves as investment adviser to the CORE U.S. Equity and Capital Growth
 Funds. Goldman Sachs Asset Management and Goldman Sachs Funds Management,
 L.P. are each referred to in this Prospectus as the "Investment Adviser."
 
 VALUE STYLE FUNDS
 
 
 Goldman Sachs' Value Investment Philosophy:
 THE INVESTMENT ADVISER SEEKS COMPANIES THAT ARE DISCOUNTED DUE TO:
 .Company-specific problems that are over-discounted in the marketplace.
 .Cyclically out-of-favor status.
 .Unrecognized positive fundamentals.
 
 THE INVESTMENT ADVISER SEEKS TO IDENTIFY VALUE THROUGH:
 .Performing intensive, hands-on fundamental research.
 .Maintaining a long-term investment horizon.
 .A team approach to decision making.
 
 Value exists when a stock's price becomes inexpensive relative to the
 company's estimated earnings and/or dividend-paying ability over the long-
 term.
 
- --------------------------------------------------------------------------------
 
 GROWTH STYLE FUNDS
 
 
 Goldman Sachs' Growth Investment Philosophy:
 1. INVEST AS IF BUYING THE COMPANY/BUSINESS, NOT SIMPLY TRADING ITS STOCK:
 .Understand the business, management, products and competition.
 .Perform intensive, hands-on fundamental research.
 .Seek businesses with strategic competitive advantages.
 
                                                                               1
<PAGE>
 
 
 .Over the long-term, expect each company's stock price ultimately to track
  the growth of the business.
 
 2. BUY HIGH-QUALITY GROWTH BUSINESSES THAT POSSESS STRONG BUSINESS FRAN-
    CHISES, FAVORABLE LONG-TERM PROSPECTS AND EXCELLENT MANAGEMENT.
 
 3. PURCHASE SUPERIOR LONG-TERM GROWTH COMPANIES AT A FAVORABLE PRICE--SEEK
    TO PURCHASE AT A FAIR VALUATION, GIVING THE INVESTOR THE POTENTIAL TO
    FULLY CAPTURE RETURNS FROM ABOVE-AVERAGE GROWTH RATES.
 
 Growth companies have earnings expectations that exceed those of the stock
 market as a whole.
 
- --------------------------------------------------------------------------------
 
 QUANTITATIVE ("CORE") STYLE FUNDS
 
 
 Goldman Sachs' CORE Investment Philosophy:
 Goldman Sachs' quantitative style of funds--CORE--emphasizes the two build-
 ing blocks of active management: STOCK SELECTION and PORTFOLIO CONSTRUCTION.
 
 I. CORE Stock Selection
 The CORE Funds use the Goldman Sachs' proprietary multifactor model
 ("Multifactor Model"), a rigorous computerized rating system, to forecast
 the returns of securities held in each Fund's portfolio. The Multifactor
 Model incorporates common variables covering measures of:
 .VALUE (price-to-book, price-to-earnings, cash flow to enterprise value)
 .MOMENTUM (earnings momentum, price momentum, sustainable growth)
 .RISK (market risk, company-specific risk, earnings risk)
 .RESEARCH (fundamental research ratings of Goldman Sachs and other analysts)
 
 ALL OF THE ABOVE FACTORS ARE CAREFULLY EVALUATED WITHIN THE MULTIFACTOR
 MODEL SINCE EACH HAS DEMONSTRATED A SIGNIFICANT IMPACT ON THE PERFORMANCE OF
 THE SECURITIES AND MARKETS THEY WERE DESIGNED TO FORECAST. STOCK SELECTION
 IN THIS PROCESS COMBINES BOTH OUR QUANTITATIVE AND QUALITATIVE ANALYSIS.
 
 II. CORE Portfolio Construction
 A proprietary COMPUTER OPTIMIZER calculates every security combination (at
 every possible weighting) to CONSTRUCT THE MOST EFFICIENT RISK/RETURN PORT-
 FOLIO given each CORE Fund benchmark. In this process, the Investment
 Adviser manages risk by limiting deviations from the benchmark, running size
 and sector neutral portfolios.
 
 Goldman Sachs CORE Funds are fully invested, broadly diversified and offer
 consistent overall portfolio characteristics. They may serve as good founda-
 tions on which to build a portfolio.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 
 REAL ESTATE SECURITIES FUND
 
 
 Goldman Sachs' Real Estate Securities Investment Philosophy:
 When choosing the Fund's securities, the Investment Adviser:
 .Selects stocks based on quality of assets, experienced management and a
  sustainable competitive advantage.
 .Seeks to buy securities at a discount to the intrinsic value of the busi-
  ness (assets and management).
 .Seeks a team approach to decision making.
 
 Over time, REITs (which stand for Real Estate Investment Trusts) have
 offered investors important diversification and competitive total returns
 versus the broad equity market.

Fund Investment Objectives and Strategies
 Goldman Sachs
 Balanced Fund
 
        FUND FACTS
- --------------------------------------------------------------------------------
 
        Objective:  Long-term growth of capital and current income
 
       Benchmarks:  S&P 500 Index and Lehman Brothers Aggregate Bond Index
 
 Investment Focus:  Large capitalization U.S. stocks and fixed-income securi-
                    ties
 
 Investment Style:  Asset Allocation, with growth and value (blend) equity
                    components
 
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks to provide long-term growth of capital and current income.
 The Fund seeks growth of capital primarily through investments in equity
 securities (stocks). The Fund seeks to provide current income through
 investment in fixed-income securities (bonds).
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Historically, stock and bond markets have often had different cycles, with
 one asset class rising when the other is falling. A balanced objective seeks
 to reduce the volatility associated with investing in a single market. There
 is no guarantee, however, that market cycles will move in opposition to one
 another or that a balanced investment program will successfully reduce vola-
 tility.
 
 Equity Securities. The Fund invests, under normal circumstances, between 45%
 and 65% of its total assets in equity securities. Although the Fund's equity
 investments consist primarily of publicly traded U.S. securities, the Fund
 may invest up to 10% of its total assets in the equity securities of foreign
 issuers, including issuers in countries with emerging markets or economies
 ("emerging countries") and equity securities quoted in foreign currencies.
 A portion of the Fund's portfolio of equity securities may be selected pri-
 marily to provide current income (includ-

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
 
 ing interests in REITs, convertible securities, preferred stocks, utility
 stocks, and interests in limited partnerships).
 
 Other. The Fund invests at least 25% of its total assets in fixed-income
 senior securities. The remainder of the Fund's assets are invested in other
 fixed-income securities and cash.
 
 The Fund's fixed-income securities primarily include:
 .Securities issued by the U.S. government, its agencies, instrumentalities
  or sponsored enterprises
 .Securities issued by corporations, banks and other issuers
 .Mortgage-backed and asset-backed securities
 
 The Fund may also invest up to 10% of its total assets in debt obligations
 (U.S. dollar and non-U.S.-dollar denominated) issued or guaranteed by one or
 more foreign governments or any of their political subdivisions, agencies or
 instrumentalities and foreign corporations or other entities. The issuers of
 these securities may be located in emerging countries.
 
 The percentage of the portfolio invested in equity and fixed-income securi-
 ties will vary from time to time as the Investment Adviser evaluates such
 securities' relative attractiveness based on market valuations, economic
 growth and inflation prospects. The allocation between equity and fixed-
 income securities is subject to the Fund's intention to pay regular quar-
 terly dividends. The amount of quarterly dividends can also be expected to
 fluctuate in accordance with factors such as prevailing interest rates and
 the percentage of the Fund's assets invested in fixed-income securities.
 
                                                                               5

 eign securities, including securities of issuers in emerging countries and

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term growth of capital and dividend income. The Fund
 seeks this objective through a broadly diversified portfolio of equity secu-
 rities of large-cap U.S. issuers that are selling at low to modest valua-
 tions relative to general market measures, such as earnings, book value and

 ble prospects for capital appreciation and/or dividend-paying ability.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, at least
 90% of its total assets in equity securities of U.S. issuers, including for-
 eign issuers that are traded in the United States.
 
 The Fund's investments are selected using both a variety of quantitative
 techniques and fundamental research in seeking to maximize the Fund's
 expected return, while maintaining risk, style, capitalization and industry
 characteristics similar to the Russell 1000 Value Index. The Fund seeks a
 portfolio comprised of companies with above average capitalizations and low
 to moderate valuations as measured by price/earnings ratios, book value and
 other fundamental accounting measures.
 
 Other. The Fund's investments in fixed-income securities are limited to
 securities that are considered cash equivalents.

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term growth of capital.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, at least
 65% of its total assets in equity securities of companies with public stock
 market capitalizations of $1 billion or less at the time of investment.
 Under normal circumstances, the Fund's investment horizon for ownership of
 stocks will be two to three years. Dividend income, if any, is an incidental
 consideration. If the market capitalization of a company held by the Fund
 increases above $1 billion, the Fund may, consistent with its investment
 objective, continue to hold the security.
 
 The Fund invests in companies which the Investment Adviser believes are
 well- managed niche businesses that have the potential to achieve high or
 improving returns on capital and/or above average sustainable growth. The
 Fund may invest in securities of small market capitalization companies which
 may have experienced financial difficulties. Investments may also be made in
 companies that are in the early stages of their life and that the Investment
 Adviser believes have significant growth potential. The Investment Adviser
 believes that the companies in which the Fund may invest offer greater
 opportunity for growth of capital than larger, more mature, better known
 companies. Although the Fund will invest primarily in publicly traded U.S.
 securities, it may invest up to 25% of its total assets in foreign securi-
 ties, including securities of issuers in emerging countries and securities
 quoted in foreign currencies.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 companies with public stock market capitalizations in excess of $1 billion
 at the time of investment and in fixed-income securities, such as corporate
 debt and bank obligations.

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks total return comprised of long-term growth of capital and
 dividend income.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all and at least 80% of its total assets in a diversified portfolio
 of equity securities of issuers that are primarily engaged in or related to
 the real estate industry. The Fund expects that a substantial portion of its
 assets will be invested in REITs and real estate industry companies.
 
 A "real estate industry company" is a company that derives at least 50% of
 its gross revenues or net profits from the ownership, development, construc-
 tion, financing, management or sale of commercial, industrial or residential
 real estate or interests therein.
 
 The Fund's investment strategy is based on the premise that property market
 fundamentals are the primary determinant of growth, underlying the success
 of companies in the real estate industry. The Investment Adviser focuses on
 companies that can achieve sustainable growth in cash flow and dividend pay-
 ing capability. The Investment Adviser attempts to purchase securities so
 that its underlying portfolio will be diversified geographically and by
 property type. Although the Fund will invest primarily in publicly traded
 U.S. securities, it may invest up to 15% of its total assets in foreign
 securities, including securities of issuers in emerging countries and secu-
 rities quoted in foreign currencies.
 
 Investing in REITs involves certain unique risks in addition to those risks
 associated with investing in the real estate industry in general. Equity
 REITs may be affected by changes in the value of the underlying property
 owned by the REITs.

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
 Mortgage REITs may be affected by the quality of any credit extended. REITs
 are dependent upon management skill, may not be diversified, and are subject
 to heavy cash flow dependency, default by borrowers and self-liquidation.
 REITs are also subject to the possibilities of failing to qualify for tax
 free pass-through of income and failing to maintain their exemptions from
 investment company registration. REITs whose underlying properties are con-
 centrated in a particular industry or geographic region are also subject to
 risks affecting such industries and regions.
 
 REITs (especially mortgage REITs) are also subject to interest rate risks.
 When interest rates decline, the value of a REIT's investment in fixed rate
 obligations can be expected to rise. Conversely, when interest rates rise,
 the value of a REIT's investment in fixed rate obligations can be expected
 to decline. In contrast, as interest rates on adjustable rate mortgage loans
 are reset periodically, yields on a REIT's investment in such loans will
 gradually align themselves to reflect changes in market interest rates,
 causing the value of such investments to fluctuate less dramatically in
 response to interest rate fluctuations than would investments in fixed rate
 obligations.
 
 The REIT investments of the Real Estate Securities Fund often do not provide
 complete tax information to the Fund until after the calendar year-end. Con-
 sequently, because of the delay, it may be necessary for the Fund to request
 permission to extend the deadline for issuance of Forms 1099-DIV beyond Jan-
 uary 31.
 
 Other. The Fund may invest up to 20% of its total assets in fixed-income
 securities, such as corporate debt and bank obligations, that offer the
 potential to further the Fund's investment objective.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

All Funds:
 
 .CREDIT/DEFAULT RISK--The risk that an issuer of fixed-income securities held
 by a Fund (which may have low credit ratings) may default on its obligation to
 pay interest and repay principal.
 .FOREIGN RISKS--The risk that when a Fund invests in foreign securities, it
 will be subject to risk of loss not typically associated with domestic
 issuers. Loss may result because of less foreign government regulation, less
 public information and less economic, political and social stability. Loss may
 also result from the imposition of exchange controls, confiscations and other
 government restrictions. A Fund will also be subject to the risk of negative
 foreign currency rate fluctuations. Foreign risks will normally be greatest
 when a Fund invests in issuers located in emerging countries.
 .EMERGING COUNTRIES RISK--The securities markets of Asian, Latin American,
 Eastern European, African and other emerging countries are less liquid, are
 especially subject to greater price volatility, have smaller market capital-
 izations, have less government regulation and are not subject to as extensive
 and frequent accounting, financial and other reporting requirements as the
 securities markets of more developed countries. Further, investment in equity
 securities of issuers located in Russia and certain other emerging countries
 involves risk of loss resulting from problems in share registration and cus-
 tody and substantial economic and political disruptions. These risks are not
 normally associated with investment in more developed countries.
 .STOCK RISK--The risk that stock prices have historically risen and fallen in
 periodic cycles. As of the date of this Prospectus, U.S. stock markets and
 certain foreign stock markets were trading at or close to record high levels.
 There is no guarantee that such levels will continue.
 .DERIVATIVES RISK--The risk that loss may result from a Fund's investments in
 options, futures, swaps, structured securities and other derivative instru-
 ments. These instruments may be leveraged so that small changes may produce
 disproportionate losses to a Fund.
 .INTEREST RATE RISK--The risk that when interest rates increase, securities
 held by a Fund will decline in value. Long-term fixed-income securities will
 normally have more price volatility because of this risk than short-term secu-
 rities.
 .MANAGEMENT RISK--The risk that a strategy used by the Investment Adviser may
 fail to produce the intended results.
 .MARKET RISK--The risk that the value of the securities in which a Fund invests
 may go up or down in response to the prospects of individual companies and/or
 general economic conditions. Price changes may be temporary or last for
 extended periods.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 .LIQUIDITY RISK--The risk that a Fund will not be able to pay redemption pro-
 ceeds within the time period stated in this Prospectus because of unusual mar-
 ket conditions, an unusually high volume of redemption requests, or other rea-
 sons. Funds that invest in non-investment grade fixed-income securities, small
 capitalization stocks, REITs and emerging country issuers will be especially
 subject to the risk that during certain periods the liquidity of particular
 issuers or industries, or all securities within these investment categories,
 will shrink or disappear suddenly and without warning as a result of adverse
 economic, market or political events, or adverse investor perceptions whether
 or not accurate.
 .OTHER RISKS--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Specific Funds:
 
 .SMALL CAP STOCK AND REIT RISK--The securities of small capitalization stocks
 and REITs involve greater risks than those associated with larger, more estab-
 lished companies and may be subject to more abrupt or erratic price movements.
 Securities of such issuers may lack sufficient market liquidity to enable a
 Fund to effect sales at an advantageous time or without a substantial drop in
 price.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Class A
 Shares from year to year; and (b) how the average annual returns of a Fund's
 Class A, B and C Shares compare to those of broad-based securities market
 indices. The bar chart and table assume reinvestment of dividends and dis-
 tributions. A Fund's past performance is not necessarily an indication of
 how the Fund will perform in the future. The average annual total return
 calculation reflects a maximum initial sales charge of 5.5% for Class A
 Shares, the assumed contingent deferred sales charge ("CDSC") for Class B
 Shares (5% maximum declining to 0% after six years), and the assumed CDSC
 for Class C Shares (1% if redeemed within 12 months of purchase). The bar
 chart does not reflect the sales loads applicable to Class A Shares. If the
 sales loads were reflected, returns would be less. Performance reflects
 expense limitations in effect. If expense limitations were not in place, a
 Fund's performance would have been reduced. The CORE Large Cap Value and
 Real Estate Securities Funds did not commence operations until December 31,
 1998 and July 27, 1998. The Strategic Growth and Growth Opportunities Funds
 had not commenced operations as of the date of this Prospectus. Since these
 Funds have less than one calendar year's performance, no performance infor-
 mation is provided in this section.

 /1/The maximum sales charge is a percentage of the offering price. A CDSC of
 1% is imposed on certain redemptions (within 18 months of purchase) of Class
 A Shares sold without an initial sales charge as part of an investment of $1
 million or more.
 /2/The maximum CDSC is a percentage of the lesser of the net asset value
 ("NAV") at the time of the redemption or the NAV when the shares were origi-
 nally purchased.
 /3/A CDSC is imposed upon Class B Shares redeemed within six years of pur-
 chase at a rate of 5% in the first year, declining to 1% in the sixth year,
 and eliminated thereafter.
 /4/A CDSC of 1% is imposed on Class C Shares redeemed within 12 months of
 purchase.
 /5/A transaction fee of $7.50 may be charged for redemption proceeds paid by
 wire. In addition to free reinvestments of dividends and distributions in
 shares of other Goldman Sachs Funds or shares of the Goldman Sachs Institu-
 tional Liquid Assets Portfolios (the "ILA Portfolios") and free automatic
 exchanges pursuant to the Automatic Exchange Program, six free exchanges are
 permitted in each 12-month period. A fee of $12.50 may be charged for each
 subsequent exchange during such period.
 /6/The Funds' annual operating expenses have been restated to reflect current
 fees, except for the CORE Large Cap Value, Strategic Growth, Growth Opportu-
 nities and Real Estate Securities Funds whose expenses are estimated for the
 current fiscal year.
 /7/The Investment Adviser has voluntarily agreed not to impose a portion of
 the management fee on the CORE U.S. Equity Fund and the CORE Large Cap Growth
 Fund equal to 0.05% and 0.15%, respectively, of such Funds' average daily net
 assets. AS A RESULT OF FEE WAIVERS, THE CURRENT MANAGEMENT FEES OF THE CORE
 U.S. EQUITY FUND AND CORE LARGE CAP GROWTH FUND ARE 0.70% AND 0.60%, RESPEC-
 TIVELY, OF SUCH FUND'S AVERAGE DAILY NET ASSETS. THE WAIVERS MAY BE TERMI-
 NATED AT ANY TIME AT THE OPTION OF THE INVESTMENT ADVISER.
 /8/The Distributor has voluntarily agreed not to impose a portion of the dis-
 tribution and service fee on the Real Estate Securities Fund equal to 0.25%
 of the Fund's average daily net assets. As a result of fee waivers, the cur-
 rent distribution and service fee of the Real Estate Securities Fund is 0.25%
 of the Fund's average daily net assets. The waiver may be terminated at any
 time at the option of the Distributor.
 /9/"Other Expenses" include transfer agency fees equal to 0.19% of the aver-
   age daily net assets of each Fund's Class A, B and C Shares, plus all other
   ordinary expenses not detailed above. The Investment Adviser has voluntar-
   ily agreed to reduce or limit "Other Expenses" (excluding management fees,
   distribution and service fees, transfer agency fees, taxes, interest and
   brokerage fees and litigation, indemnification and other extraordinary
   expenses) to the following percentages of each Fund's average daily net
   assets:

Example
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in Class A,
B or C Shares of a Fund for the time periods indicated and then redeem all of
your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that a Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

 The hypothetical example assumes that a CDSC will not apply to redemptions
 of Class A Shares within the first 18 months. Class B Shares convert to
 Class A Shares eight years after purchase; therefore, Class A expenses are
 used in the hypothetical example after year eight.
 Certain institutions that sell Fund Shares and/or their salespersons may
 receive other compensation in connection with the sale and distribution of
 Class A, Class B and Class C Shares for services to their customers'
 accounts and/or the Funds. For additional information regarding such
 compensation, see "What I Should Know When I Purchase Shares Through An

 GSAM is a separate operating division of Goldman Sachs, which registered as
 an investment adviser in 1981. GSFM, a registered investment adviser since
 1990, is a Delaware limited partnership which is an affiliate of Goldman
 Sachs. The Goldman Sachs Group, L.P., which controls the Investment Advis-
 ers, announced that it will pursue an initial public offering of the firm in
 the late spring or early summer of 1999. Simultaneously with the offering,
 the Goldman Sachs Group, L.P. will merge into The Goldman Sachs Group, Inc.
 As of February 28, 1999, GSAM and GSFM, together with their affiliates,
 acted as investment adviser or distributor for assets in excess of $199 bil-
 lion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser makes the investment decisions
 for the Funds and places purchase and sale orders for the Funds' portfolio
 transactions in U.S. and foreign markets. As permitted by applicable law,
 these orders may be directed to any brokers, including Goldman Sachs and its
 affiliates. While the Investment Adviser is ultimately responsible for the
 management of the Funds, it is able to draw upon the research and expertise
 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.
 
                                                                              53

   ical services to the Funds
 . Arranges for the preparation of all required tax returns, reports to share-

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that a Fund
 could sustain losses during periods in which Goldman Sachs and its affili-
 ates and other accounts achieve significant profits on their trading for
 proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly

 known as the "Year 2000 Problem"). To the extent these systems conduct
 forward-looking calculations, these computer problems may occur prior to
 January 1, 2000. Like other investment companies and financial and business
 organizations, the Funds could be adversely affected in their ability to
 process securities trades, price securities, provide shareholder account
 services and otherwise conduct normal business operations if the Investment
 Adviser or other Fund service providers do not adequately address this prob-
 lem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 . The Investment Adviser has established a dedicated group to analyze these
   issues and to implement the systems modifications necessary to prepare for
   the Year 2000 Problem.
 . The Investment Adviser has sought assurances from the Funds' other service
   providers that they are taking the steps necessary so that they do not
   experience Year 2000 Problems, and the Investment Adviser will continue to
   monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
 
                                                                              61

Dividends
 
Each Fund pays dividends from its net investment income and distributions from
net realized capital gains. You may choose to have dividends and distributions
paid in:
 . Cash
 . Additional shares of the same class of the same Fund
 . Shares of the same or an equivalent class of another Goldman Sachs Fund. Spe-
  cial restrictions may apply for certain ILA Portfolios. See the Additional
  Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from net capital gains
are declared and paid as follows:

From time to time a portion of a Fund's dividends may constitute a return of
capital.
 
At the time of an investor's purchase of shares of a Fund, a portion of the NAV
per share may be represented by undistributed income or realized or unrealized
appreciation of the Fund's portfolio securities. Therefore, subsequent distri-
butions on such shares from such income or realized appreciation may be taxable
to the investor even if the NAV of the shares is, as a result of the distribu-
tions, reduced below the cost of such shares and the distributions (or portions
thereof) represent a return of a portion of the purchase price.

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 . Refuse to open an account if you fail to (i) provide a social security num-
   ber or other taxpayer identification number; or (ii) certify that such num-
   ber is correct (if required to do so under applicable law).
 . Reject or restrict any purchase or exchange order by a particular purchaser
   (or group of related purchasers). This may occur, for example, when a pat-
   tern of
 
                                                                              65

  frequent purchases, sales or exchanges of shares of a Fund is evident, or
  if purchases, sales or exchanges are, or a subsequent abrupt redemption
  might be, of a size that would disrupt management of a Fund.
 . Modify or waive the minimum investment amounts.
 . Modify the manner in which shares are offered.
 . Modify the sales charge rates applicable to future purchases of shares.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange shares is deter-
 mined by a Fund's NAV and share class. Each class calculates its NAV as fol-
 lows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
 The Funds' investments are valued based on market quotations or if accurate
 quotations are not readily available, the fair value of the Fund's invest-
 ments may be determined in good faith under procedures established by the
 Trustees.
 
 . NAV per share of each share class is calculated by the Fund's custodian on
   each business day as of the close of regular trading on the New York Stock
   Exchange (normally 4:00 p.m. New York time). Fund shares will not be priced
   on any day the New York Stock Exchange is closed.
 . When you buy shares, you pay the NAV next calculated after the Funds
   receive your order in proper form, plus any applicable sales charge.
 . When you sell shares, you receive the NAV next calculated after the Funds
   receive your order in proper form, less any applicable CDSC.
 
 NOTE: THE TIME AT WHICH TRANSACTIONS AND SHARES ARE PRICED AND THE TIME BY
 WHICH ORDERS MUST BE RECEIVED MAY BE CHANGED IN CASE OF AN EMERGENCY OR IF
 REGULAR TRADING ON THE NEW YORK STOCK EXCHANGE IS STOPPED AT A TIME OTHER
 THAN 4:00 P.M. NEW YORK TIME.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be

 In addition, the impact of events that occur after the publication of market

 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS A SHARES
 
 What Is The Offering Price Of Class A Shares?
 THE OFFERING PRICE OF CLASS A SHARES OF EACH FUND IS THE NEXT DETERMINED NAV
 PER SHARE PLUS AN INITIAL SALES CHARGE PAID TO GOLDMAN SACHS AT THE TIME OF
 PURCHASE OF SHARES. The sales charge varies depending upon the amount you
 purchase. In some cases, described below, the initial sales charge may be
 eliminated altogether, and the offering price will be the NAV per share. The
 current sales charges and commissions paid to Authorized Dealers are as fol-
 lows:

   * Dealer's allowance may be changed periodically. During special promo-
     tions, the entire sales charge may be allowed to Authorized Dealers.
     Authorized Dealers to whom substantially the entire sales charge is
     allowed may be deemed to be "underwriters" under the Securities Act of
     1933.
  ** No sales charge is payable at the time of purchase of Class A Shares of
     $1 million or more, but a CDSC of 1% may be imposed in the event of cer-
     tain redemptions within 18 months of purchase.
 *** The Distributor pays a one-time commission to Authorized Dealers who
     initiate or are responsible for purchases of $1 million or more of
     shares of the Funds equal to 1.00% of the amount under $3 million, 0.50%
     of the next $2 million, and 0.25% thereafter. The Distributor may also
     pay, with respect to all or a portion of the amount purchased, a commis-
     sion in accordance with the foregoing schedule to Authorized Dealers who
     initiate or are responsible for purchases of $500,000 or more by certain
     pension and profit sharing plans, pension funds and other company-spon-
     sored benefit plans investing in the Funds which satisfy the criteria
     set forth below in "When Are Class A Shares Not Subject To A Sales
     Load?" or $1 million or more by certain "wrap" accounts. Purchases by
     such plans will be made at NAV with no initial sales charge, but if all
     of the shares held are redeemed within 18 months after the end of the
     calendar month in which such purchase was made, a CDSC of 1% may be
     imposed upon the plan sponsor or the third party administrator. In addi-
     tion, Authorized Dealers will remit to the Distributor such payments
     received in connection with "wrap" accounts in the event that shares are
     redeemed within 18 months after the end of the calendar month in which
     the purchase was made.

 What Else Do I Need To Know About Class A Shares' CDSC?
 Purchases of $1 million or more of Class A Shares will be made at NAV with
 no initial sales charge. However, if you redeem shares within 18 months
 after the end of the calendar month in which the purchase was made, exclud-
 ing any period of time in which the shares were exchanged into and remained
 invested in an equivalent class of an ILA Portfolio, a CDSC of 1% may be
 imposed. The CDSC may not be imposed if your Authorized Dealer enters into
 an agreement with the Distributor to return all or an applicable prorated
 portion of its commission to the Distributor. The CDSC is waived on redemp-
 tions in certain circumstances. See "In What Situations May The CDSC On
 Class A, B Or C Shares Be Waived Or Reduced?" below.
 
 When Are Class A Shares Not Subject To A Sales Load?
 Class A Shares of the Funds may be sold at NAV without payment of any sales
 charge to the following individuals and entities:
 
 . Goldman Sachs, its affiliates or their respective officers, partners,
   directors or employees (including retired employees and former partners),
   any partnership of which Goldman Sachs is a general partner, any Trustee or
   officer of the Trust and designated family members of any of these individ-
   uals;
 . Qualified retirement plans of Goldman Sachs;
 . Trustees or directors of investment companies for which Goldman Sachs or an
   affiliate acts as sponsor;
 . Any employee or registered representative of any Authorized Dealer or their
   respective spouses, children and parents;
 . Banks, trust companies or other types of depository institutions investing
   for their own account or investing for discretionary or non-discretionary
   accounts;
 . Any state, county or city, or any instrumentality, department, authority or
   agency thereof, which is prohibited by applicable investment laws from pay-
   ing a sales charge or commission in connection with the purchase of shares
   of a Fund;
 . Pension and profit sharing plans, pension funds and other company-sponsored
   benefit plans that:
   . Buy shares of Goldman Sachs Funds worth $500,000 or more; or
   . Have 100 or more eligible employees at the time of purchase; or
   . Certify that they expect to have annual plan purchases of shares of
     Goldman Sachs Funds of $200,000 or more; or
   . Are provided administrative services by certain third-party administra-
     tors that have entered into a special service arrangement with Goldman
     Sachs relating to such plans; or
   . Have at the time of purchase aggregate assets of at least $2,000,000;

 . "Wrap" accounts for the benefit of clients of broker-dealers, financial
   institutions or financial planners, provided they have entered into an
   agreement with GSAM specifying aggregate minimums and certain operating
   policies and standards;
 . Registered investment advisers investing for accounts for which they
   receive asset-based fees;
 . Accounts over which GSAM or its advisory affiliates have investment discre-
   tion; or
 . Shareholders receiving distributions from a qualified retirement plan
   invested in the Goldman Sachs Funds and reinvesting such proceeds in a
   Goldman Sachs IRA.
 
 YOU MUST CERTIFY ELIGIBILITY FOR ANY OF THE ABOVE EXEMPTIONS ON YOUR ACCOUNT
 APPLICATION AND NOTIFY THE FUND IF YOU NO LONGER ARE ELIGIBLE FOR THE EXEMP-
 TION. The Fund will grant you an exemption subject to confirmation of your
 entitlement. You may be charged a fee if you effect your transactions
 through a broker or agent.
 
 How Can The Sales Charge On Class A Shares Be Reduced?
 . RIGHT OF ACCUMULATION: When buying Class A Shares in Goldman Sachs Funds,
   your current aggregate investment determines the initial sales load you
   pay. You may qualify for reduced sales charges when the current market
   value of holdings (shares at current offering price), plus new purchases,
   reaches $50,000 or more. Class A Shares of any of the Goldman Sachs Funds
   may be combined under the Right of Accumulation. To qualify for a reduced
   sales load, you or your Authorized Dealer must notify the Funds' Transfer
   Agent at the time of investment that a quantity discount is applicable. Use
   of this service is subject to a check of appropriate records. The Addi-
   tional Statement has more information about the Right of Accumulation.
 . STATEMENT OF INTENTION: You may obtain a reduced sales charge by means of a
   written Statement of Intention which expresses your non-binding commitment
   to invest in the aggregate $50,000 or more (not counting reinvestments of
   dividends and distributions) within a period of 13 months in Class A Shares
   of one or more Goldman Sachs Fund. Any investments you make during the
   period will receive the discounted sales load based on the full amount of
   your investment commitment. If the investment commitment of the Statement
   of Intention is not met prior to the expiration of the 13-month period, the
   entire amount will be subject to the higher applicable sales charge. By
   signing the Statement of Intention, you authorize the Transfer Agent to
   escrow and redeem Class A Shares in your account to pay this additional
   charge. The Additional Statement has more information about the Statement
   of Intention, which you should read carefully.
 
                                                                              69

 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS B SHARES
 
 
 What Is The Offering Price Of Class B Shares?
 YOU MAY PURCHASE CLASS B SHARES OF THE FUNDS AT THE NEXT DETERMINED NAV
 WITHOUT AN INITIAL SALES CHARGE. HOWEVER, CLASS B SHARES REDEEMED WITHIN SIX
 YEARS OF PURCHASE WILL BE SUBJECT TO A CDSC AT THE RATES SHOWN IN THE TABLE
 BELOW BASED ON HOW LONG YOU HELD YOUR SHARES.
 
 The CDSC schedule is as follows:

  Sixth                          1%
  Seventh and thereafter       None
 ----------------------------------------
</TABLE>
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class B Shares, including the payment of compensation to Authorized Dealers.
 A commission equal to 4% of the amount invested is paid to Authorized Deal-
 ers.
 
 What Should I Know About The Automatic Conversion Of Class B Shares?
 Class B Shares of a Fund will automatically convert into Class A Shares of
 the same Fund at the end of the calendar quarter that is eight years after
 the purchase date.
 
 If you acquire Class B Shares of a Fund by exchange from Class B Shares of
 another Goldman Sachs Fund, your Class B Shares will convert into Class A
 Shares of such Fund based on the date of the initial purchase and the CDSC
 schedule of that purchase.
 
 If you acquire Class B Shares through reinvestment of distributions, your
 Class B Shares will convert into Class A Shares based on the date of the
 initial purchase of the shares on which the distribution was paid.
 
 The conversion of Class B Shares to Class A Shares will not occur at any
 time the Funds are advised that such conversions may constitute taxable
 events for federal tax purposes, which the Funds believe is unlikely. If
 conversions do not occur as a

 result of possible taxability, Class B Shares would continue to be subject
 to higher expenses than Class A Shares for an indeterminate period.
 
 A COMMON QUESTION ABOUT THE PURCHASE OF CLASS C SHARES
 
 
 What Is The Offering Price Of Class C Shares?
 YOU MAY PURCHASE CLASS C SHARES OF THE FUNDS AT THE NEXT DETERMINED NAV
 WITHOUT PAYING AN INITIAL SALES CHARGE. HOWEVER, IF YOU REDEEM CLASS C
 SHARES WITHIN 12 MONTHS OF PURCHASE, A CDSC OF 1% WILL BE DEDUCTED FROM THE
 REDEMPTION PROCEEDS; PROVIDED THAT IN CONNECTION WITH PURCHASES BY PENSION
 AND PROFIT SHARING PLANS, PENSION FUNDS AND OTHER COMPANY-SPONSORED BENEFIT
 PLANS, WHERE ALL OF THE CLASS C SHARES ARE REDEEMED WITHIN 12 MONTHS OF PUR-
 CHASE, A CDSC OF 1% MAY BE IMPOSED UPON THE PLAN SPONSOR OR THIRD PARTY
 ADMINISTRATOR.
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class C Shares, including the payment of compensation to Authorized Dealers.
 An amount equal to 1% of the amount invested is paid by the Distributor to
 Authorized Dealers.
 
 COMMON QUESTIONS APPLICABLE TO THE PURCHASE OF CLASS A, B
 AND C SHARES
 
 
 What Else Do I Need To Know About The CDSC On Class A, B Or C Shares?
 . The CDSC is based on the lesser of the NAV of the shares at the time of
   redemption or the original offering price (which is the original NAV).
   . No CDSC is charged on shares acquired from reinvested dividends or capi-
     tal gains distributions.
   . No CDSC is charged on the per share appreciation of your account over the
     initial purchase price.
   . When counting the number of months since a purchase of Class B or Class C
     Shares was made, all payments made during a month will be combined and
     considered to have been made on the first day of that month.
 . To keep your CDSC as low as possible, each time you place a request to sell
   shares, the Funds will first sell any shares in your account that do not
   carry a CDSC and then the shares in your account that have been held the
    longest.
 
                                                                              71
<PAGE>
 
 
 
 In What Situations May The CDSC On Class A, B Or C Shares Be Waived Or
 Reduced?
 The CDSC on Class A, Class B and Class C Shares that are subject to a CDSC
 may be waived or reduced if the redemption relates to:
 . Retirement distributions or loans to participants or beneficiaries from
   pension and profit sharing plans, pension funds and other company-sponsored
   benefit plans (each a "Retirement Plan");
 . The death or disability (as defined in Section 72(m)(7) of the Internal
   Revenue Code of 1986, as amended (the "Code")) of a participant or benefi-
   ciary in a Retirement Plan;
 . Hardship withdrawals by a participant or beneficiary in a Retirement Plan;
 . Satisfying the minimum distribution requirements of the Code;
 . Establishing "substantially equal periodic payments" as described under
   Section 72(t)(2) of the Code;
 . The separation from service by a participant or beneficiary in a Retirement
   Plan;
 . The death or disability (as defined in Section 72(m)(7) of the Code) of a
   shareholder if the redemption is made within one year of the event;
 . Excess contributions distributed from a Retirement Plan;
 . Distributions from a qualified Retirement Plan invested in the Goldman
   Sachs Funds which are being rolled over to a Goldman Sachs IRA; or
 . Redemption proceeds which are to be reinvested in accounts or non-regis-
   tered products over which GSAM or its advisory affiliates have investment
   discretion.
 
 In addition, Class A, B and C Shares subject to a systematic withdrawal plan
 may be redeemed without a CDSC. The Funds reserve the right to limit such
 redemptions, on an annual basis, to 12% each of the value of your Class B
 and C Shares and 10% of the value of your Class A Shares.
 
 How Do I Decide Whether To Buy Class A, B Or C Shares?
 THE DECISION AS TO WHICH CLASS TO PURCHASE DEPENDS ON THE AMOUNT YOU INVEST,
 THE INTENDED LENGTH OF THE INVESTMENT AND YOUR PERSONAL SITUATION.
 
 . CLASS A SHARES. If you are making an investment of $50,000 or more that
   qualifies for a reduced sales charge, you should consider purchasing Class
   A Shares.
 . CLASS B SHARES. If you plan to hold your investment for at least six years
   and would prefer not to pay an initial sales charge, you might consider
   purchasing Class B Shares. By not paying a front-end sales charge, your
   entire investment in Class B Shares is available to work for you from the
   time you make your initial investment. However, the distribution and serv-
   ice fee paid by Class B

                                                               SHAREHOLDER GUIDE
 
  Shares will cause your Class B Shares (until conversion to Class A Shares)
  to have a higher expense ratio, and thus, lower performance and lower divi-
  dend payments (to the extent dividends are paid) than Class A Shares. A
  maximum purchase limitation of $250,000 in the aggregate normally applies
  to Class B Shares.
 . CLASS C SHARES. If you are unsure of the length of your investment or plan
  to hold your investment for less than six years and would prefer not to pay
  an initial sales charge, you may prefer Class C Shares. By not paying a
  front-end sales charge, your entire investment in Class C Shares is avail-
  able to work for you from the time you make your initial investment. Howev-
  er, the distribution and service fee paid by Class C Shares will cause your
  Class C Shares to have a higher expense ratio, and thus lower performance
  and lower dividend payments (to the extent dividends are paid) than Class A
  Shares (or Class B Shares after conversion to Class A Shares).
  Although Class C Shares are subject to a CDSC for only 12 months, Class C
  Shares do not have the conversion feature applicable to Class B Shares and
  your investment will therefore pay higher distribution fees indefinitely.
  A maximum purchase limitation of $1,000,000 in the aggregate normally
  applies to purchases of Class C Shares.
 
 NOTE: AUTHORIZED DEALERS MAY RECEIVE DIFFERENT COMPENSATION FOR SELLING
 CLASS A, CLASS B OR CLASS C SHARES.
 
 In addition to Class A, Class B and Class C Shares, each Fund also offers
 other classes of shares to investors. These other share classes are subject
 to different fees and expenses (which affect performance), have different
 minimum investment requirements and are entitled to different services.
 Information regarding these other share classes may be obtained from your
 sales representative or from Goldman Sachs by calling the number on the back
 cover of this Prospectus.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Class A, Class B And Class C Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. EACH FUND WILL REDEEM ITS SHARES UPON REQUEST ON
 ANY BUSINESS DAY AT THE NAV NEXT DETERMINED AFTER RECEIPT OF SUCH REQUEST IN
 PROPER FORM, SUBJECT TO ANY APPLICABLE CDSC. You may request that redemption
 proceeds be sent to you by check or by wire (if the wire instructions are on
 record). Redemptions may be requested in writing or by telephone.

                     within any 7 calendar day period
                   . Proceeds which are sent directly to a Goldman

 -------------------------------------------------------------------------
</TABLE>
 When Do I Need A Signature Guarantee To Redeem Shares?
 A signature guarantee is required if:
 . You are requesting in writing to redeem shares in an amount over $50,000;
 . You would like the redemption proceeds sent to an address that is not your
   address of record; or
 . You would like to change the bank designated on your Account Application.
 
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federal savings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.
 Additional documentation may be required for executors, trustees or corpora-
 tions or when deemed appropriate by the Transfer Agent.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 The Trust may accept telephone redemption instructions from any person iden-
 tifying himself or
 
74
<PAGE>
 
                                                               SHAREHOLDER GUIDE
 
 herself as the owner of an account or the owner's registered representative
 where the owner has not declined in writing to use this service. Thus, you
 risk possible losses if a telephone redemption is not authorized by you.
 
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs and NFDS each employ reasonable proce-
 dures specified by the Trust to confirm that such instructions are genuine.
 If reasonable procedures are not employed, the Trust may be liable for any
 loss due to unauthorized or fraudulent transactions. The following general
 policies are currently in effect:
 . All telephone requests are recorded.
 . Proceeds of telephone redemption requests will be sent only to your address
   of record or authorized bank account designated in the Account Application
   (unless you provide written instructions and a signature guarantee, indi-
   cating another address or account) and exchanges of shares normally will be
   made only to an identically registered account.
 . Telephone redemptions will not be accepted during the 30-day period follow-
   ing any change in your address of record.
 . The telephone redemption option does not apply to shares held in a "street
   name" account. "Street name" accounts are accounts maintained and serviced
   by your Authorized Dealer. If your account is held in "street name," you
   should contact your registered representative of record, who may make tele-
   phone redemptions on your behalf.
 . The telephone redemption option may be modified or terminated at any time.
 
 NOTE: IT MAY BE DIFFICULT TO MAKE TELEPHONE REDEMPTIONS IN TIMES OF DRASTIC
 ECONOMIC OR MARKET CONDITIONS.
 
 How Are Redemption Proceeds Paid?
 BY WIRE: You may arrange for your redemption proceeds to be wired as federal
 funds to the bank account designated in your Account Application. The fol-
 lowing general policies govern wiring redemption proceeds:
 . Redemption proceeds will normally be wired on the next business day in fed-
   eral funds (for a total of one business day delay), but may be paid up to
   three business days following receipt of a properly executed wire transfer
   redemption request. If you are selling shares you recently paid for by
   check, the Fund will pay you when your check has cleared, which may take up
   to 15 days. If the Federal Reserve Bank is closed on the day that the
   redemption proceeds would ordinarily be wired, wiring the redemption pro-
   ceeds may be delayed one additional business day.
 . A transaction fee of $7.50 may be charged for payments of redemption pro-
   ceeds by wire. Your bank may also charge wiring fees. You should contact
   your bank directly to learn whether it charges such fees.
 
                                                                              75
<PAGE>
 
 
 . To change the bank designated on your Account Application, you must send
   written instructions (with your signature guaranteed) to the Transfer
   Agent.
 . Neither the Trust, Goldman Sachs nor any Authorized Dealer assume any
   responsibility for the performance of your bank or any intermediaries in
   the transfer process. If a problem with such performance arises, you should
   deal directly with your bank or any such intermediaries.
 BY CHECK: You may elect to receive your redemption proceeds by check.
 Redemption proceeds paid by check will normally be mailed to the address of
 record within three business days of a properly executed redemption request.
 If you are selling shares you recently paid for by check, the Fund will pay
 you when your check has cleared, which may take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 
 The Trust reserves the right to:
 . Redeem your shares if your account balance is less than $50 as a result of
   a redemption. The Funds will not redeem your shares on this basis if the
   value of your account falls below the minimum account balance solely as a
   result of market conditions. The Funds will give you 60 days' prior written
   notice to allow you to purchase sufficient additional shares of the Fund in
   order to avoid such redemption.
 . Redeem your shares in other circumstances determined by the Board of Trust-
   ees to be in the best interests of the Trust.
 . Pay redemptions by a distribution in-kind of securities (instead of cash).
   If you receive redemption proceeds in-kind, you should expect to incur
   transaction costs upon the disposition of those securities.
 
 Can I Reinvest Redemption Proceeds In The Same Or Another Goldman Sachs
 Fund?
 You may redeem shares of a Fund and reinvest a portion or all of the redemp-
 tion proceeds (plus any additional amounts needed to round off purchases to
 the nearest full share) at NAV. To be eligible for this privilege, you must
 hold the shares you want to redeem for at least 30 days and you must rein-
 vest the share proceeds within 90 days after you redeem. You may reinvest as
 follows:
  . Class A or B Shares--Class A Shares of the same Fund or any other Goldman
    Sachs Fund
  . Class C Shares--Class C Shares of the same Fund or any other Goldman
    Sachs Fund

 . You should obtain and read the applicable prospectuses before investing in
   any other Funds.
 . If you pay a CDSC upon redemption of Class A or Class C Shares and then
   reinvest in Class A or Class C Shares as described above, your account will
   be credited with the amount of the CDSC you paid. The reinvested shares
   will, however, continue to be subject to a CDSC. The holding period of the
   shares acquired through reinvestment will include the holding period of the
   redeemed shares for purposes of computing the CDSC payable upon a subse-
   quent redemption. For Class B Shares, you may reinvest the redemption pro-
   ceeds in Class A Shares at NAV but the amount of the CDSC paid upon redemp-
   tion of the Class B Shares will not be credited to your account.
 . The reinvestment privilege may be exercised at any time in connection with
   transactions in which the proceeds are reinvested at NAV in a tax-sheltered
   retirement plan. In other cases, the reinvestment privilege may be exer-
   cised once per year upon receipt of a written request.
 . You may be subject to tax as a result of a redemption. You should consult
   your tax adviser concerning the tax consequences of a redemption and rein-
   vestment.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange shares of a Fund at NAV without the imposition of an ini-
 tial sales charge or CDSC at the time of exchange for shares of the same
 class or an equivalent class of any other Goldman Sachs Fund. The exchange
 privilege may be materially modified or withdrawn at any time upon 60 days'
 written notice to you.

 You should keep in mind the following factors when making or considering an
 exchange:
 . You should obtain and carefully read the prospectus of the Fund you are
   acquiring before making an exchange.
 . Six free exchanges are allowed in each 12 month period.
 . A $12.50 fee may be charged for each subsequent exchange.
 . There is no charge for exchanges made pursuant to the Automatic Exchange
   Program.
 . The exchanged shares may later be exchanged for shares of the same class
   (or an equivalent class) of the original Fund at the next determined NAV
   without the imposition of an initial sales charge or CDSC if the amount in
   the Fund resulting from such exchanges is less than the largest amount on
   which you have previously paid the applicable sales charge.
 . When you exchange shares subject to a CDSC, no CDSC will be charged at that
   time. The exchanged shares will be subject to the CDSC of the shares origi-
   nally held. For purposes of determining the amount of the applicable CDSC,
   the length of time you have owned the shares will be measured from the date
   you acquired the original shares subject to a CDSC and will not be affected
   by a subsequent exchange.
 . Eligible investors may exchange certain classes of shares for another class
   of shares of the same Fund. For further information, call Goldman Sachs
   Funds at 1-800-526-7384.
 . All exchanges which represent an initial investment in a Fund must satisfy
   the minimum initial investment requirements of that Fund.
 . Exchanges are available only in states where exchanges may be legally made.
 . It may be difficult to make telephone exchanges in times of drastic eco-
   nomic or market conditions.
 . Goldman Sachs and NFDS may use reasonable procedures described under "What
   Do I Need to Know About Telephone Redemption Requests?" in an effort to
   prevent unauthorized or fraudulent telephone exchange requests.
 . Telephone exchanges normally will be made only to an identically registered
   account. Shares may be exchanged among accounts with different names,
   addresses and social security or other taxpayer identification numbers only
   if the exchange instructions are in writing and accompanied by a signature
   guarantee.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.

 SHAREHOLDER SERVICES
 
 
 Can I Arrange To Have Automatic Investments Made On A Regular Basis?
 You may be able to make systematic cash investments through your bank via
 ACH transfer or your checking account via bank draft each month. Forms for
 this option are available from Goldman Sachs, your Authorized Dealer or you
 may check the appropriate box on the Account Application.
 
 Can My Dividends And Distributions From A Fund Be Invested In Other Funds?
 You may elect to cross-reinvest dividends and capital gain distributions
 paid by a Fund in shares of the same class or an equivalent class of any
 other Goldman Sachs Fund.
 . Shares will be purchased at NAV.
 . No initial sales charge or CDSC will be imposed.
 . You may elect cross-reinvestment into an identically registered account or
   an account registered in a different name or with a different address,
   social security number or taxpayer identification number provided that the
   account has been properly established, appropriate signature guarantees
   obtained and the minimum initial investment has been satisfied.
 
 Can I Arrange To Have Automatic Exchanges Made On A Regular Basis?
 You may elect to exchange automatically a specified dollar amount of shares
 of a Fund for shares of the same class or an equivalent class of any other
 Goldman Sachs Fund.
 . Shares will be purchased at NAV.
 . No initial sales charge is imposed.
 . Shares subject to a CDSC acquired under this program may be subject to a
   CDSC at the time of redemption from the Fund into which the exchange is
   made depending upon the date and value of your original purchase.
 . Automatic exchanges are made monthly on the 15th day of each month or the
   first business day thereafter.
 . Minimum dollar amount: $50 per month.
 
 What Else Should I Know About Cross-Reinvestments And Automatic Exchanges?
 Cross-reinvestments and automatic exchanges are subject to the following
 conditions:
 . You must hold $5,000 or more in the Fund which is paying the dividend or
   from which the exchange is being made.
 
                                                                              79
<PAGE>
 
 
 . You must invest an amount in the Fund into which cross-reinvestments or
   automatic exchanges are being made that is equal to that Fund's minimum
   initial investment or continue to cross-reinvest or to make automatic
   exchanges until such minimum initial investment is met.
 . You should obtain and read the prospectus of the Fund into which dividends
   are invested or automatic exchanges are made.
 
 Can I Have Automatic Withdrawals Made On A Regular Basis?
 You may draw on your account systematically via check or ACH transfer in any
 amount of $50 or more.
 . It is normally undesirable to maintain a systematic withdrawal plan at the
   same time that you are purchasing additional Class A, Class B or Class C
   Shares because of the sales charge imposed on your purchases of Class A
   Shares or the imposition of a CDSC on your redemptions of Class A, Class B
   or Class C Shares.
 . You must have a minimum balance of $5,000 in a Fund.
 . Checks are mailed on or about the 25th day of each month.
 . Each systematic withdrawal is a redemption and therefore a taxable transac-
   tion.
 . The CDSC applicable to Class A, Class B or Class C Shares redeemed under
   the systematic withdrawal plan may be waived.
 
 What Types of Reports Will I Be Sent Regarding My Investment?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-526-7384. You will also be provided with a
 printed confirmation for each transaction in your account and an individual
 quarterly account statement. A year-to-date statement for your account will
 be provided upon request made to Goldman Sachs. If your account is held in
 "street name" you may receive your statement and confirmations on a differ-
 ent schedule. The Funds do not generally provide sub-accounting services.
 
 What Should I Know When I Purchase Shares Through An Authorized Dealer?
 Authorized Dealers and other financial intermediaries may provide varying
 arrangements for their clients to purchase and redeem Fund shares. They may
 charge additional fees not described in this Prospectus to their customers
 for such services.
 
 If shares of a Fund are held in a "street name" account with an Authorized
 Dealer, all recordkeeping, transaction processing and payments of distribu-
 tions relating to your account will be performed by the Authorized Dealer,
 and not by the Fund and its Transfer Agent. Since the Funds will have no
 record of your

                                                               SHAREHOLDER GUIDE
 
 transactions, you should contact the Authorized Dealer to purchase, redeem
 or exchange shares, to make changes in or give instructions concerning the
 account or to obtain information about your account. The transfer of shares
 in a "street name" account to an account with another dealer or to an
 account directly with the Fund involves special procedures and will require
 you to obtain historical purchase information about the shares in the
 account from the Authorized Dealer.
 
 Authorized Dealers and other financial intermediaries may be authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and if approved by the Trust, to
 designate other intermediaries to accept such orders. In these cases:
 . A Fund will be deemed to have received an order that is in proper form when
   the order is accepted by an Authorized Dealer or intermediary on a business
   day, and the order will be priced at the Fund's NAV per share (adjusted for
   any applicable sales charge) next determined after such acceptance.
 . Authorized Dealers and intermediaries are responsible for transmitting
   accepted orders to the Funds within the time period agreed upon by them.
 
 You should contact your Authorized Dealer or intermediary to learn whether
 it is authorized to accept orders for the Trust.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Authorized Dealers and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Autho-
 rized Dealers depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 DISTRIBUTION SERVICES AND FEES
 
 
 What Are The Different Distribution And Service Fees Paid By Class A, B and
 C Shares?
 The Trust has adopted distribution and service plans (each a "Plan") under
 which Class A, Class B and Class C Shares bear distribution and service fees
 paid to Authorized Dealers and Goldman Sachs. If the fees received by
 Goldman Sachs pursuant to the Plans exceed its expenses, Goldman Sachs may
 realize a profit from
 
                                                                              81
<PAGE>
 
 
 their arrangements. Goldman Sachs pays the distribution and service fees on
 a quarterly basis.
 
 Under the Plans, Goldman Sachs is entitled to a monthly fee from each Fund
 for distribution services equal, on an annual basis, to 0.25%, 0.75% and
 0.75%, respectively, of a Fund's average daily net assets attributed to
 Class A, Class B and Class C Shares. Because these fees are paid out of the
 Fund's assets on an ongoing basis, over time, these fees will increase the
 cost of your investment and may cost you more than paying other types of
 such charges.
 
 The distribution fees are subject to the requirements of Rule 12b-1 under
 the Act, and may be used (among other things) for:
 . Compensation paid to and expenses incurred by Authorized Dealers, Goldman
   Sachs and their respective officers, employees and sales representatives;
 . Commissions paid to Authorized Dealers;
 . Allocable overhead;
 . Telephone and travel expenses;
 . Interest and other costs associated with the financing of such compensation
   and expenses;
 . Printing of prospectuses for prospective shareholders;
 . Preparation and distribution of sales literature or advertising of any
   type; and
 . All other expenses incurred in connection with activities primarily
   intended to result in the sale of Class A, Class B and Class C Shares.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.75% distribution fee as an ongoing commission to Authorized Dealers
 after the shares have been held for one year.
 
 PERSONAL ACCOUNT MAINTENANCE SERVICES AND FEES
 
 
 Under the Plans, Goldman Sachs is also entitled to receive a separate fee
 equal on an annual basis to 0.25% of each Fund's average daily net assets
 attributed to Class A Shares (Real Estate Securities Fund only), Class B or
 Class C Shares. This fee is for personal and account maintenance services,
 and may be used to make payments to Goldman Sachs, Authorized Dealers and
 their officers, sales representatives and employees for responding to
 inquiries of, and furnishing assistance to, shareholders regarding ownership
 of their shares or their accounts or similar services not otherwise provided
 on behalf of the Funds. If the fees received by Goldman Sachs pursuant to
 the Plans exceed its expenses, Goldman Sachs may realize a profit from this
 arrangement.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.25% ongoing service fee to Authorized Dealers after the shares have
 been held for one year.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Fund distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Fund's net investment income, certain net realized
 foreign exchange gains and net short-term capital gains. They are taxable as
 long-term capital gains to the extent they are attributable to the Fund's
 excess of net long-term capital gains over net short-term capital losses.
 The tax status of any distribution is the same regardless of how long you
 have been in the Fund and whether you reinvest in additional shares or take
 the distribution as cash. Certain distributions paid by a Fund in January of
 a given year may be taxable to shareholders as if received the prior Decem-
 ber 31. The tax status and amounts of the distributions for each calendar
 year will be detailed in your annual tax statement from the Fund.
 
 A Fund's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Fund receives from U.S. domestic
 corporations may be eligible, in the hands of the corporate shareholders,
 for the corporate dividends-received deduction, subject to certain holding
 period requirements and debt financing limitations.
 
 Each Fund may be subject to foreign withholding or other foreign taxes on
 income or gain from certain foreign securities. In general, the Funds may
 deduct these taxes in computing their taxable income.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In its efforts to adhere to these requirements, the
 Funds may have to limit their investment activity in some types of instru-
 ments.
 
                                                                              83
<PAGE>
 
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements for the periods that you hold shares.) Any loss rec-
 ognized on shares held for six months or less will be treated as a long-term
 capital loss to the extent of any capital gain dividends that were received
 with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from a Fund or on the value of the shares
 held by you. More tax information is provided in the Additional Statement.
 You should also consult your own tax adviser for information regarding all
 tax consequences applicable to your investments in the Funds.

Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 A. General Portfolio Risks
 
 The Funds will be subject to the risks associated with equity securities.
 "Equity securities" include common stocks, preferred stocks, interests in
 real estate investment trusts, convertible debt obligations, convertible
 preferred stocks, equity interests in trusts, partnerships, joint ventures,
 limited liability companies and similar enterprises, warrants and stock pur-
 chase rights. In general, stock values fluctuate in response to the activi-
 ties of individual companies and in response to general market and economic
 conditions. Accordingly, the value of the stocks that a Fund holds may
 decline over short or extended periods. The stock markets tend to be cycli-
 cal, with periods when stock prices generally rise and periods when prices
 generally decline. The volatility of equity securities means that the value
 of your investment in the Funds may increase or decrease. As of the date of
 this Prospectus, certain stock markets were trading at or close to record
 high levels and there can be no guarantee that such levels will continue.
 
 To the extent that a Fund invests in fixed-income securities, that Fund will
 also be subject to the risks associated with its fixed-income securities.
 These risks include interest rate risk, credit risk and call/extension risk.
 In general, interest rate risk involves the risk that when interest rates
 decline, the market value of fixed-income securities tends to increase. Con-
 versely, when interest rates increase, the market value of fixed-income
 securities tends to decline. Credit risk involves the risk that an issuer
 could default on its obligations, and a Fund will not recover its invest-
 ment. Call risk and extension risk are normally present in mortgage-backed
 securities and asset-backed securities. For example, homeowners have the
 option to prepay their mortgages. Therefore, the duration of a security
 backed by home mortgages can either shorten (call risk) or lengthen (exten-
 sion risk). In general, if interest rates on new mortgage loans fall suffi-
 ciently below the interest rates on existing outstanding mortgage loans, the
 rate of prepayment would be expected to increase. Conversely, if mortgage
 loan interest rates rise above the interest rates on existing outstanding
 mortgage loans, the rate of prepayment would be expected to decrease. In
 either case, a change in the prepayment rate can result in losses to invest-
 ors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by dividing the lesser of the dollar amount of sales or
 purchases of portfolio securi-
 
                                                                              85
<PAGE>
 
 
 ties by the average monthly value of a Fund's portfolio securities, exclud-
 ing securities having a maturity at the date of purchase of one year or
 less. See "Financial Highlights" in Appendix B for a statement of the Funds'
 historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all investment objectives and policies not specifically designated as
 fundamental are non-fundamental and may be changed without shareholder
 approval. If there is a change in a Fund's investment objective, you should
 consider whether that Fund remains an appropriate investment in light of
 your then current financial position and needs.
 
 B. Other Portfolio Risks
 
 
 RISKS OF INVESTING IN SMALL CAPITALIZATION COMPANIES AND REITS. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such securities. Small capitalization companies
 and REITs may be thinly traded and may have to be sold at a discount from
 current market prices or in small lots over an extended period of time. In
 addition, these securities are subject to the risk that during certain peri-
 ods the liquidity of particular issuers or industries, or all securities in
 these investment categories, will shrink or disappear suddenly and without
 warning as a result of adverse economic or market conditions, or adverse
 investor perceptions whether or not accurate. Because of the lack of suffi-
 cient market liquidity, a Fund may incur losses because it will be required
 to effect sales at a disadvantageous time and only then at a substantial
 drop in price. Small capitalization companies and REITs include "unseasoned"
 issuers that do not have an established financial history; often have lim-
 ited product lines, markets or financial resources; may depend on or use a
 few key personnel for management; and may be susceptible to losses and risks
 of bankruptcy. Transaction costs for these investments are often higher than
 those of larger capitalization companies. Investments in small capitaliza-
 tion companies and REITs may be more difficult to price precisely than other
 types of securities because of their characteristics and lower trading vol-
 umes.

 RISKS OF FOREIGN INVESTMENTS. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts after January 1, 1999 that refer to existing currencies
 rather than the euro; the establishment and maintenance of exchange rates
 for currencies being converted into the euro; the fluctuation of the euro
 relative to non-euro currencies during the transition period from January 1,
 1999 to December 31, 2001 and beyond; whether the interest rate, tax and
 labor regimes of European countries participating in the euro will converge
 over time; and whether the conversion of the currencies of other countries
 that now are or may in the future become members of the European Union
 ("EU"), may have an impact on the euro. These or other factors, including
 political and economic risks, could cause market disruptions, and could
 adversely affect the value of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Efforts in foreign countries to remediate potential Year
 
                                                                              87

 2000 problems are not as extensive as those in the United States. As a
 result, the operations of foreign markets, foreign issuers and foreign gov-
 ernments may be disrupted by the Year 2000 Problem, and the investment port-
 folio of a Fund may be adversely affected. Furthermore, with respect to cer-
 tain foreign countries, there is a possibility of nationalization,
 expropriation or confiscatory taxation, imposition of withholding or other
 taxes on dividend or interest payments (or, in some cases, capital gains),
 limitations on the removal of funds or other assets of the Funds, and polit-
 ical or social instability or diplomatic developments which could affect
 investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such debt, and a Fund may have limited recourse to compel
 payment in the event of a default. Periods of economic uncertainty may
 result in the volatility of market prices of sovereign debt, and in turn a
 Fund's NAV, to a greater extent than the volatility inherent in debt obliga-
 tions of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Funds may also invest in European Depository
 Receipts ("EDRs") or other similar instruments representing securities of
 foreign issuers. ADRs represent the right to receive securities of foreign
 issuers deposited in a domestic bank or a correspondent bank. Prices of ADRs
 are quoted in U.S. dollars, and ADRs are traded in the United States. EDRs
 and GDRs are receipts evidencing an arrangement with a non-U.S. bank. EDRs
 and GDRs are not necessarily quoted in the same currency as the underlying
 security.
 
 RISKS OF EMERGING COUNTRIES. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are gener-

                                                                      APPENDIX A
 
 ally located in the Asia-Pacific region, Eastern Europe, Latin and South
 America and Africa. A Fund's purchase and sale of portfolio securities in
 certain emerging countries may be constrained by limitations as to daily
 changes in the prices of listed securities, periodic trading or settlement
 volume and/or limitations on aggregate holdings of foreign investors. Such
 limitations may be computed based on the aggregate trading volume by or
 holdings of a Fund, the Investment Adviser, its affiliates and their respec-
 tive clients and other service providers. A Fund may not be able to sell
 securities in circumstances where price, trading or settlement volume limi-
 tations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, it is anticipated that
 a Fund may invest in such countries through other investment funds in such
 countries.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and
 
                                                                              89
<PAGE>
 
 
 ethnic, religious and racial disaffection, among other factors, have also
 led to social unrest, violence and/or labor unrest in some emerging coun-
 tries. Unanticipated political or social developments may result in sudden
 and significant investment losses. Investing in emerging countries involves
 greater risk of loss due to expropriation, nationalization, confiscation of
 assets and property or the imposition of restrictions on foreign investments
 and on repatriation of capital invested.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Fund in emerging countries may not be as sound as the
 creditworthiness of firms used in more developed countries. As a result, the
 Fund may be subject to a greater risk of loss if a securities firm defaults
 in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than investments in countries with more developed securities mar-
 kets (such as the United States, Japan and most Western European countries).
 A Fund's investments in emerging countries are subject to the risk that the
 liquidity of a particular investment, or investments generally, in such
 countries will shrink or disappear suddenly and without warning as a result
 of adverse economic, market or political conditions or adverse investor per-
 ceptions, whether or not accurate. Because of the lack of sufficient market
 liquidity, a Fund may incur losses because it will be required to effect
 sales at a disadvantageous time and only then at a substantial drop in
 price. Investments in emerging countries may be more difficult to price pre-
 cisely because of the characteristics discussed above and lower trading vol-
 umes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.

 RISKS OF DERIVATIVE INVESTMENTS. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities and currency transactions involve additional risk of
 loss. Loss can result from a lack of correlation between changes in the
 value of derivative instruments and the portfolio assets (if any) being
 hedged, the potential illiquidity of the markets for derivative instruments,
 or the risks arising from margin requirements and related leverage factors
 associated with such transactions. The use of these management techniques
 also involves the risk of loss if the Investment Adviser is incorrect in its
 expectation of fluctuations in securities prices, interest rates or currency
 prices. Each Fund may also invest in derivative investments for non-hedging
 purposes (that is, to seek to increase total return). Investing for non-
 hedging purposes is considered a speculative practice and presents even
 greater risk of loss.
 
 RISKS OF ILLIQUID SECURITIES. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 . Both domestic and foreign securities that are not readily marketable
 . Certain stripped mortgage-backed securities
 . Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
 . Certain over-the-counter options
 . Certain restricted securities, unless it is determined, based upon a review
   of the trading markets for a specific restricted security, that such
   restricted security is eligible for resale pursuant to Rule 144A under the
   Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 CREDIT RISKS. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Further informa-
 tion is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse
 
                                                                              91
<PAGE>
 
 
 economic conditions or changing circumstances may weaken their issuers'
 capacity to pay interest and repay principal. A security will be deemed to
 have met a rating requirement if it receives the minimum required rating
 from at least one such rating organization even though it has been rated
 below the minimum rating by one or more other rating organizations, or if
 unrated by such rating organizations, determined by the Investment Adviser
 to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 TEMPORARY INVESTMENT RISKS. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 . U.S. government securities
 . Commercial paper rated at least A-2 by Standard & Poor's or P-2 by Moody's
 . Certificates of deposit
 . Bankers' acceptances
 . Repurchase agreements
 . Non-convertible preferred stocks and non-convertible corporate bonds with a
   remaining maturity of less than one year
 
 When a Fund's assets are invested in such instruments, the Fund may not be
 achieving its investment objective.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 CONVERTIBLE SECURITIES. Each Fund may invest in convertible securities. Con-
 vertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which a Fund invests are subject to the same
 rating criteria as its other investments in
 
92
<PAGE>
 
                                                                      APPENDIX A
 
 fixed-income securities. Convertible securities have both equity and fixed-
 income risk characteristics. Like all fixed-income securities, the value of
 convertible securities is susceptible to the risk of market losses attribut-
 able to changes in interest rates. Generally, the market value of convert-
 ible securities tends to decline as interest rates increase and, conversely,
 to increase as interest rates decline. However, when the market price of the
 common stock underlying a convertible security exceeds the conversion price
 of the convertible security, the convertible security tends to reflect the
 market price of the underlying common stock. As the market price of the
 underlying common stock declines, the convertible security, like a fixed-
 income security, tends to trade increasingly on a yield basis, and thus may
 not decline in price to the same extent as the underlying common stock.
 
 FOREIGN CURRENCY TRANSACTIONS. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, certain Funds may also
 enter into such transactions to seek to increase total return, which is con-
 sidered a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in connection with investments in foreign securities when, in the
 judgment of the Investment Adviser, it would be beneficial to convert such
 currency into U.S. dollars at a later date (e.g., the Investment Adviser may
 anticipate the foreign currency to appreciate against the U.S. dollar).
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are
 
                                                                              93
<PAGE>
 
 
 not guaranteed by an exchange or clearinghouse, a default on a contract
 would deprive a Fund of unrealized profits, transaction costs or the bene-
 fits of a currency hedge or could force the Fund to cover its purchase or
 sale commitments, if any, at the current market price.
 
 STRUCTURED SECURITIES. Each Fund may invest in structured securities. Struc-
 tured securities are securities whose value is determined by reference to
 changes in the value of specific currencies, interest rates, commodities,
 indices or other financial indicators (the "Reference") or the relative
 change in two or more References. The interest rate or the principal amount
 payable upon maturity or redemption may be increased or decreased depending
 upon changes in the applicable Reference. Structured securities may be posi-
 tively or negatively indexed, so that appreciation of the Reference may pro-
 duce an increase or decrease in the interest rate or value of the security
 at maturity. In addition, changes in the interest rates or the value of the
 security at maturity may be a multiple of changes in the value of the Refer-
 ence. Consequently, structured securities may present a greater degree of
 market risk than other types of fixed-income securities and may be more vol-
 atile, less liquid and more difficult to price accurately than less complex
 securities.
 
 REITS. Each Fund may invest in REITS. REITS are pooled investment vehicles
 that invest primarily in either real estate or real estate related loans.
 The value of a REIT is affected by changes in the value of the properties
 owned by the REIT or securing mortgage loans held by the REIT. REITs are
 dependent upon the ability of the REITs' managers, and are subject to heavy
 cash flow dependency, default by borrowers and the qualification of the
 REITs under applicable regulatory requirements for favorable income tax
 treatment. REITs are also subject to risks generally associated with invest-
 ments in real estate including possible declines in the value of real
 estate, general and local economic conditions, environmental problems and
 changes in interest rates. To the extent that assets underlying a REIT are
 concentrated geographically, by property type or in certain other respects,
 these risks may be heightened. A Fund will indirectly bear its proportionate
 share of any expenses, including management fees, paid by a REIT in which it
 invests.
 
 OPTIONS ON SECURITIES, SECURITIES INDICES AND FOREIGN CURRENCIES. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which they may invest or on any securities index comprised of
 securities in which they may invest. A Fund

                                                                      APPENDIX A
 
 may also, to the extent that it invests in foreign securities, purchase and
 sell (write) put and call options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater illiquidity and credit risks.
 
 FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 government securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their term structures, sector selec-
 tion and durations in accordance with their investment objectives and poli-
 cies. Each Fund may also enter into closing purchase and sale transactions
 with respect to such contracts and options. A Fund will engage in futures
 and related options transactions for bona fide hedging purposes as defined
 in regulations of the Commodity Futures Trading Commission or to seek to
 increase total return to the extent permitted by such regulations. A Fund
 may not purchase or sell futures contracts or purchase or sell related
 options to seek to increase total return, except for closing purchase or
 sale transactions, if immediately thereafter the sum of the amount of ini-
 tial margin deposits and premiums paid on the Fund's outstanding positions
 in futures and related options entered
 
                                                                              95
<PAGE>
 
 
 into for the purpose of seeking to increase total return would exceed 5% of
 the market value of the Fund's net assets.
 
 Futures contracts and related options present the following risks:
 . While a Fund may benefit from the use of futures and options on futures,
   unanticipated changes in interest rates, securities prices or currency
   exchange rates may result in poorer overall performance than if the Fund
   had not entered into any futures contracts or options transactions.
 . Because perfect correlation between a futures position and portfolio posi-
   tion that is intended to be protected is impossible to achieve, the desired
   protection may not be obtained and a Fund may be exposed to additional risk
   of loss.
 . The loss incurred by a Fund in entering into futures contracts and in writ-
   ing call options on futures is potentially unlimited and may exceed the
   amount of the premium received.
 . Futures markets are highly volatile and the use of futures may increase the
   volatility of a Fund's NAV.
 . As a result of the low margin deposits normally required in futures trad-
   ing, a relatively small price movement in a futures contract may result in
   substantial losses to a Fund.
 . Futures contracts and options on futures may be illiquid, and exchanges may
   limit fluctuations in futures contract prices during a single day.
 . Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 EQUITY SWAPS. Each Fund may invest in equity swaps. Equity swaps allow the
 parties to a swap agreement to exchange the dividend income or other compo-
 nents of return on an equity investment (for example, a group of equity
 securities or an index) for a component of return on another non-equity or
 equity investment.
 
 An equity swap may be used by a Fund to invest in a market without owning or
 taking physical custody of securities in circumstances in which direct
 investment may be restricted for legal reasons or is otherwise impractical.
 Equity swaps are derivatives and their value can be very volatile. To the
 extent that the Investment Adviser does not accurately analyze and predict
 the potential relative fluctuation of the components swapped with another
 party, a Fund may suffer a loss. The value of some components of an equity
 swap (such as the dividends on a common stock) may also be sensitive to
 changes in interest rates. Furthermore, a Fund may suffer a loss if the
 counterparty defaults.
 
 WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS. Each Fund may purchase when-
 issued securities and make contracts to purchase or sell securities for a
 fixed price at a future date beyond customary settlement time. When-issued
 securities are securities that have been authorized, but not yet issued.
 When-issued securities are purchased in order to secure what is considered
 to be an advantageous price and yield to the Fund at the time
 
96
<PAGE>
 
                                                                      APPENDIX A
 
 of entering into the transaction. A forward commitment involves the entering
 into a contract to purchase or sell securities for a fixed price at a future
 date beyond the customary settlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 REPURCHASE AGREEMENTS. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with primary dealers in U.S. government securities and member banks of the
 Federal Reserve System which furnish collateral at least equal in value or
 market price to the amount of their repurchase obligation.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's costs associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Certain
 Funds, together with other registered investment companies having advisory
 agreements with the Investment Adviser or any of its affiliates, may trans-
 fer uninvested cash balances into a single joint account, the daily aggre-
 gate balance of which will be invested in one or more repurchase agreements.
 
 LENDING OF PORTFOLIO SECURITIES. Each Fund may engage in securities lending.
 Securities lending involves the lending of securities owned by a Fund to
 financial institutions such as certain broker-dealers. The borrowers are
 required to secure their loan continuously with cash, cash equivalents, U.S.
 government securities or letters of credit in an amount at least equal to
 the market value of the securities loaned. Cash collateral may be invested
 in cash equivalents. If the Investment Adviser determines to make securities
 loans, the value of the securities loaned may not exceed 33 1/3% of the
 value of the total assets of a Fund (including the loan collateral).
 
                                                                              97
<PAGE>
 
 
 
 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 SHORT SALES AGAINST-THE-BOX. Certain Funds may make short sales against-the-
 box. A short sale against-the-box means that at all times when a short posi-
 tion is open the Fund will own an equal amount of securities sold short, or
 securities convertible into or exchangeable for, without payment of any fur-
 ther consideration, an equal amount of the securities of the same issuer as
 the securities sold short.
 
 PREFERRED STOCK, WARRANTS AND RIGHTS. Each Fund may invest in preferred
 stock, warrants and rights. Preferred stocks are securities that represent
 an ownership interest providing the holder with claims on the issuer's earn-
 ings and assets before common stock owners but after bond owners. Unlike
 debt securities, the obligations of an issuer of preferred stock, including
 dividend and other payment obligations, may not typically be accelerated by
 the holders of such preferred stock on the occurrence of an event of default
 or other non-compliance by the issuer of the preferred stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.
 
 OTHER INVESTMENT COMPANIES. Each Fund may invest in securities of other
 investment companies (including SPDRs and WEBs, as defined below) subject to
 statutory limitations prescribed by the Act. These limitations include a
 prohibition on any Fund acquiring more than 3% of the voting shares of any
 other investment company, and a prohibition on investing more than 5% of a
 Fund's total assets in securities of any one investment company or more than
 10% of its total assets in securities of all investment companies. A Fund
 will indirectly bear its proportionate share of any management fees and
 other expenses paid by such other investment companies. Such other invest-
 ment companies will have investment objectives, policies and restrictions
 substantially similar to those of the acquiring Fund and will be subject to
 substantially the same risks.
 
 . STANDARD & POOR'S DEPOSITORY RECEIPTS. The Funds may, consistent with their
    investment policies, purchase Standard & Poor's Depository Receipts
   ("SPDRs"). SPDRs are securities traded on the American Stock Exchange
   ("AMEX") that represent ownership in the SPDR Trust, a trust which has been
   established to accumulate and hold a portfolio of common stocks that is
   intended to track the price performance and dividend yield of the S&P 500.
   The SPDR Trust is sponsored by a subsidiary of the AMEX. SPDRs may be used
   for several reasons, including, but not limited to, facilitating the han-
   dling of

                                                                      APPENDIX A
 
  cash flows or trading, or reducing transaction costs. The price movement of
  SPDRs may not perfectly parallel the price action of the S&P 500.
 
 . WORLD EQUITY BENCHMARK SHARES. World Equity Benchmark Shares ("WEBS") are
  shares of an investment company that invests substantially all of its
  assets in securities included in the MSCI indices for specified countries.
  WEBS are listed on the AMEX and were initially offered to the public in
  1996. The market prices of WEBS are expected to fluctuate in accordance
  with both changes in the NAVs of their underlying indices and supply and
  demand of WEBS on the AMEX. To date, WEBS have traded at relatively modest
  discounts and premiums to their NAVs. However, WEBS have a limited operat-
  ing history and information is lacking regarding the actual performance and
  trading liquidity of WEBS for extended periods or over complete market
  cycles. In addition, there is no assurance that the requirements of the
  AMEX necessary to maintain the listing of WEBS will continue to be met or
  will remain unchanged. In the event substantial market or other disruptions
  affecting WEBS should occur in the future, the liquidity and value of a
  Fund's shares could also be substantially and adversely affected. If such
  disruptions were to occur, a Fund could be required to reconsider the use
  of WEBS as part of its investment strategy.
 
 UNSEASONED COMPANIES. Each Fund may invest in companies (including predeces-
 sors) which have operated less than three years, except that this limitation
 does not apply to debt securities which have been rated investment grade or
 better by at least one NRSRO. The securities of such companies may have lim-
 ited liquidity, which can result in their being priced higher or lower than
 might otherwise be the case. In addition, investments in unseasoned compa-
 nies are more speculative and entail greater risk than do investments in
 companies with an established operating record.
 
 CORPORATE DEBT OBLIGATIONS. Corporate debt obligations include bonds, notes,
 debentures and other obligations of corporations to pay interest and repay
 principal, and include securities issued by banks and other financial insti-
 tutions. Each Fund may invest in corporate debt obligations issued by U.S.
 and certain non-U.S. issuers which issue securities denominated in the U.S.
 dollar (including Yankee and Euro obligations). In addition to obligations
 of corporations, corporate debt obligations include securities issued by
 banks and other financial institutions and supranational entities (i.e., the
 World Bank, the International Monetary Fund, etc.).
 
 BANK OBLIGATIONS. Each Fund may invest in obligations issued or guaranteed
 by U.S. or foreign banks. Bank obligations, including without limitations,
 time deposits, bankers' acceptances and certificates of deposit, may be gen-
 eral obligations of the parent bank or may be limited to the issuing branch
 by the terms of the specific obligations or by government regulations. Banks
 are subject to extensive but
 
                                                                              99

 different governmental regulations which may limit both the amount and types
 of loans which may be made and interest rates which may be charged. In addi-
 tion, the profitability of the banking industry is largely dependent upon
 the availability and cost of funds for the purpose of financing lending
 operations under prevailing money market conditions. General economic condi-
 tions as well as exposure to credit losses arising from possible financial
 difficulties of borrowers play an important part in the operation of this
 industry.
 
 U.S. GOVERNMENT SECURITIES AND RELATED CUSTODIAL RECEIPTS. Each Fund may
 invest in U.S. government securities and related custodial receipts. U.S.
 government securities include U.S. Treasury obligations and obligations
 issued or guaranteed by U.S. government agencies, instrumentalities or spon-
 sored enterprises. U.S. government securities may be supported by (a) the
 full faith and credit of the U.S. Treasury (such as the Government National
 Mortgage Association ("Ginnie Mae")); (b) the right of the issuer to borrow
 from the U.S. Treasury (such as securities of the Student Loan Marketing
 Association); (c) the discretionary authority of the U.S. government to pur-
 chase certain obligations of the issuer (such as the Federal National Mort-
 gage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. government
 securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. government securities, where the interest and principal compo-
 nents of stripped U.S. government securities are traded independently.
 
 Interests in U.S. government securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S.
 government.
 
 MORTGAGE-BACKED SECURITIES. Certain Funds may invest in mortgage-backed
 securities. Mortgage-backed securities represent direct or indirect partici-
 pations in, or are collateralized by and payable from, mortgage loans
 secured by real property. Mortgage-backed securities can be backed by either
 fixed rate mortgage loans or adjustable rate mortgage loans, and may be
 issued by either a governmental or non-governmental entity. Privately issued
 mortgage-backed securities are normally structured with one or more types of
 "credit enhancement." However, these mortgage-backed securities typically do
 not have the same credit standing as U.S. government guaranteed mortgage-
 backed securities.
 
 Mortgage-backed securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an

                                                                      APPENDIX A
 
 investor with a specified interest in the cash flow from a pool of under-
 lying mortgages or of other mortgage-backed securities. CMOs are issued in
 multiple classes. In most cases, payments of principal are applied to the
 CMO classes in the order of their respective stated maturities, so that no
 principal payments will be made on a CMO class until all other classes hav-
 ing an earlier stated maturity date are paid in full. A REMIC is a CMO that
 qualifies for special tax treatment and invests in certain mortgages princi-
 pally secured by interests in real property and other permitted investments.
 
 Mortgaged-backed securities also include stripped mortgage-backed securities
 ("SMBS"), which are derivative multiple class mortgage-backed securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other mortgage-backed securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 ASSET-BACKED SECURITIES. Certain Funds may invest in asset-backed securi-
 ties. Asset-backed securities are securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed securities are often subject to more rapid repayment than their
 stated maturity date would indicate as a result of the pass-through of pre-
 payments of principal on the underlying loans. During periods of declining
 interest rates, prepayment of loans underlying asset-backed securities can
 be expected to accelerate. Accordingly, a Fund's ability to maintain posi-
 tions in such securities will be affected by reductions in the principal
 amount of such securities resulting from prepayments, and its ability to
 reinvest the returns of principal at comparable yields is subject to gener-
 ally prevailing interest rates at that time. Asset-backed securities present
 credit risks that are not presented by mortgage-backed securities. This is
 because asset-backed securities generally do not have the benefit of a secu-
 rity interest in collateral that is comparable to mortgage assets. There is
 the possibility that, in some cases, recoveries on repossessed collateral
 may not be available to support payments on these securities. In the event
 of a default, a Fund may suffer a loss if it cannot sell collateral quickly
 and receive the amount it is owed.
 
 BORROWINGS. Each Fund can borrow money from banks and other financial insti-
 tutions in amounts not exceeding one-third of their total assets for tempo-
 rary or emergency purposes. A Fund may not make additional investments if
 borrowings exceed 5% of its total assets.
 
                                                                             101
<PAGE>
 
 
 
 MORTGAGE DOLLAR ROLLS. Certain Funds may enter into mortgage dollar rolls. A
 mortgage dollar roll involves the sale by a Fund of securities for delivery
 in the current month. The Fund simultaneously contracts with the same
 counterparty to repurchase substantially similar (same type, coupon and
 maturity) but not identical securities on a specified future date. During
 the roll period, the Fund loses the right to receive principal and interest
 paid on the securities sold. However, the Fund benefits to the extent of any
 difference between (a) the price received for the securities sold and (b)
 the lower forward price for the future purchase and/or fee income plus the
 interest earned on the cash proceeds of the securities sold. Unless the ben-
 efits of a mortgage dollar roll exceed the income, capital appreciation and
 gain or loss due to mortgage prepayments that would have been realized on
 the securities sold as part of the roll, the use of this technique will
 diminish the Fund's performance.
 
 Successful use of mortgage dollar rolls depends upon the Investment Advis-
 er's ability to predict correctly interest rates and mortgage prepayments.
 If the Investment Adviser is incorrect in its prediction, a Fund may experi-
 ence a loss. For financial reporting and tax purposes, the Funds treat mort-
 gage dollar rolls as two separate transactions: one involving the purchase
 of a security and a separate transaction involving a sale. The Funds do not
 currently intend to enter into mortgage dollar rolls that are accounted for
 as a financing and do not treat them as borrowings.
 
 YIELD CURVE OPTIONS. Certain Funds may enter into options on the yield
 "spread" or differential between two securities. Such transactions are
 referred to as "yield curve" options. In contrast to other types of options,
 a yield curve option is based on the difference between the yields of desig-
 nated securities, rather than the prices of the individual securities, and
 is settled through cash payments. Accordingly, a yield curve option is prof-
 itable to the holder if this differential widens (in the case of a call) or
 narrows (in the case of a put), regardless of whether the yields of the
 underlying securities increase or decrease.
 
 The trading of yield curve options is subject to all of the risks associated
 with the trading of other types of options. In addition, such options pres-
 ent a risk of loss even if the yield of one of the underlying securities
 remains constant, or if the spread moves in a direction or to an extent
 which was not anticipated.
 
 REVERSE REPURCHASE AGREEMENTS. Certain Funds may enter into reverse repur-
 chase agreements. Reverse repurchase agreements involve the sale of securi-
 ties held by a Fund subject to the Fund's agreement to repurchase them at a
 mutually agreed upon date and price (including interest). These transactions
 may be entered into as a temporary measure for emergency purposes or to meet
 redemption requests. Reverse repurchase agreements may also be entered into
 when the Invest-

                                                                      APPENDIX A
 
 ment Adviser expects that the interest income to be earned from the invest-
 ment of the transaction proceeds will be greater than the related interest
 expense. Reverse repurchase agreements involve leveraging. If the securities
 held by a Fund decline in value while these transactions are outstanding,
 the NAV of the Fund's outstanding shares will decline in value by propor-
 tionately more than the decline in value of the securities. In addition,
 reverse repurchase agreements involve the risk that the interest income
 earned by a Fund (from the investment of the proceeds) will be less than the
 interest expense of the transaction, that the market value of the securities
 sold by a Fund will decline below the price the Fund is obligated to pay to
 repurchase the securities, and that the securities may not be returned to
 the Fund.
 
 MUNICIPAL SECURITIES. Certain Funds may invest in securities and instruments
 issued by state and local government issuers. Municipal securities in which
 a Fund may invest consist of bonds, notes, commercial paper and other
 instruments (including participating interest in such securities) issued by
 or on behalf of states, territories and possessions of the United States
 (including the District of Columbia) and their political subdivisions, agen-
 cies or instrumentalities. Such securities may pay fixed, variable or float-
 ing rates of interest. Municipal securities are often issued to obtain funds
 for various public purposes, including the construction of a wide range of
 public facilities such as bridges, highways, housing, hospitals, mass trans-
 portation, schools, streets and water and sewer works. Other public purposes
 for which municipal securities may be issued include refunding outstanding
 obligations, obtaining funds for general operating expenses, and obtaining
 funds to lend to other public institutions and facilities. Municipal securi-
 ties in which a Fund may invest include private activity bonds, municipal
 leases, certificates of participation, pre-funded municipal securities and
 auction rate securities.
 
 INTEREST RATE SWAPS, MORTGAGE SWAPS, CREDIT SWAPS, CURRENCY SWAPS AND INTER-
 EST RATE CAPS, FLOORS AND COLLARS. Interest rate swaps involve the exchange
 by a Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest rate swaps in that
 they represent commitments to pay and receive interest. The notional princi-
 pal amount, however, is tied to a reference pool or pools of mortgages.
 Credit swaps involve the receipt of floating or fixed rate payments in
 exchange for assuming potential credit losses of an underlying security.
 Credit swaps give one party to a transaction the right to dispose of or
 acquire an asset (or group of assets), or the right to receive or make a
 payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest
 
                                                                             103
<PAGE>
 
 
 rate, to receive payment of interest on a notional principal amount from the
 party selling such interest rate cap. The purchase of an interest rate floor
 entitles the purchaser, to the extent that a specified index falls below a
 predetermined interest rate, to receive payments of interest on a notional
 principal amount from the party selling the interest rate floor. An interest
 rate collar is the combination of a cap and a floor that preserves a certain
 return within a predetermined range of interest rates.
 
 Certain Funds may enter into swap transactions for hedging purposes or to
 seek to increase total return. The use of interest rate, mortgage, credit
 and currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If the Investment Adviser is incorrect in its forecasts of market
 value, interest rates and currency exchange rates, the investment perfor-
 mance of a Fund would be less favorable than it would have been if these
 investment techniques were not used.
 
 LOAN PARTICIPATIONS. Certain Funds may invest in loan participations. A loan
 participation is an interest in a loan to a U.S. or foreign company or other
 borrower which is administered and sold by a financial intermediary. A Fund
 may only invest in loans to issuers in whose obligations it may otherwise
 invest. Loan participation interests may take the form of a direct or co-
 lending relationship with the corporate borrower, an assignment of an inter-
 est in the loan by a co-lender or another participant, or a participation in
 the seller's share of the loan. When a Fund acts as co-lender in connection
 with a participation interest or when it acquires certain participation
 interests, the Fund will have direct recourse against the borrower if the
 borrower fails to pay scheduled principal and interest. In cases where the
 Fund lacks direct recourse, it will look to the agent bank to enforce appro-
 priate credit remedies against the borrower. In these cases, the Fund may be
 subject to delays, expenses and risks that are greater than those that would
 have been involved if the Fund had purchased a direct obligation (such as
 commercial paper) of such borrower. Moreover, under the terms of the loan
 participation, the Fund may be regarded as a creditor of the agent bank
 (rather than of the underlying corporate borrower), so that the Fund may
 also be subject to the risk that the agent bank may become insolvent.
 
 INVERSE FLOATERS. Certain Funds may invest in inverse floating rate debt
 securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has not
 been in operation for less than five years). Certain information reflects
 financial results for a single Fund share. The total returns in the table
 represent the rate that an investor would have earned or lost on an invest-
 ment in a Fund (assuming reinvestment of all dividends and distributions).
 This information has been audited by Arthur Andersen LLP, whose report,
 along with a Fund's financial statements, is included in the Fund's annual
 report (available upon request).

Prior Performance of Similarly Advised Accounts of the Investment Adviser
 
 CORE LARGE CAP VALUE FUND
 
 The following table sets forth the Investment Adviser's composite perfor-
 mance data relating to the historical performance of all discretionary pri-
 vate accounts managed by the Investment Adviser that have investment objec-
 tives, policies, and strategies substantially similar to the CORE Large Cap
 Value Fund. The information is provided to illustrate the past performance
 of the Investment Adviser in managing substantially similar accounts as mea-
 sured against the Russell 1000 Value Index and does not represent the per-
 formance of the CORE Large Cap Value Fund. Investors should not consider
 this performance data as a substitute for the performance of the CORE Large
 Cap Value Fund nor should investors consider this data as an indication of
 future performance of the CORE Large Cap Value Fund or of the Investment
 Adviser. The Russell 1000 Value Index is unmanaged and investors cannot
 invest directly in the Index.

 In accordance with the standards of the Association for Investment Manage-
 ment and Research ("AIMR"), the Investment Adviser's composite performance
 information was calculated on a time-weighted and asset-weighted total
 return basis which includes realized and unrealized gains and losses plus
 income. The composite performance is net of applicable investment management
 fees, brokerage commissions, execution costs and custodial fees, without
 provision for federal and state taxes, if any. Total return performance of
 the CORE Large Cap Value Fund will be calculated in accordance with the reg-
 ulations of the SEC. The SEC standardized average annualized total return is
 neither time-weighted nor asset-weighted and is determined for specified
 periods by computing the annualized percentage change in the value of an
 initial amount that is invested in a share class of the Fund at the maximum
 public offering price. Investors should be aware that the differences in
 methodology between AIMR and SEC requirements could result in different per-
 formance data for identical time periods.
 
 Performance reflects the deduction of the maximum 5.5% front-end sales
 charge with respect to Class A Shares and the maximum CDSC with respect to
 Class B (5%) and Class C Shares (1%). All returns presented reflect the
 reinvestment of dividends and other earnings. The weighted-average expenses
 of the private accounts used in calculating the Investment Adviser's net
 composite performance data were 0.59% annualized, which are lower than the
 estimated expenses of Class A, Class B and Class C Shares of the CORE Large
 Cap Value Fund stated under "Fund Fees and Expenses" above. The performance
 of the private accounts

 would have been lower if they had been subject to the expenses of the CORE
 Large Cap Value Fund. In addition, the private accounts are not subject to
 the same diversification requirements, specific tax restrictions and invest-
 ment limitations imposed on the CORE Large Cap Value Fund by the Act and
 Subchapter M of the Code. Consequently, the performance results of the
 Investment Adviser's composite could have been adversely affected if the
 private accounts had been regulated as investment companies under the fed-
 eral securities laws.

 The following table sets forth the Investment Adviser's composite perfor-

 vate accounts managed by the Investment Adviser that have investment objec-
 tives, policies, and strategies substantially similar to the Strategic
 Growth Fund. The information is provided to illustrate the past performance
 of the Investment Adviser in managing substantially similar accounts as mea-
 sured against the S&P 500 Index and does not represent the performance of
 the Strategic Growth Fund. Investors should not consider this performance
 data as a substitute for the performance of the Strategic Growth Fund nor
 should investors consider this data as an indication of future performance
 of the Strategic Growth Fund or of the Investment Adviser. The S&P 500 Index
 is unmanaged and investors cannot invest directly in the Index.

General Investment Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the Balanced,
 Growth and Income, CORE Large Cap Value, CORE Large Cap Growth, CORE Small
 Cap Equity, Strategic Growth, Growth Opportunities, Mid Cap Value, Small Cap
 Value and Real Estate Securities Funds. Goldman Sachs Funds Management, L.P.
 serves as investment adviser to the CORE U.S. Equity and Capital Growth
 Funds. Goldman Sachs Asset Management and Goldman Sachs Funds Management,
 L.P. are each referred to in this Prospectus as the "Investment Adviser."
 
 VALUE STYLE FUNDS
 
 
 Goldman Sachs' Value Investment Philosophy:
 THE INVESTMENT ADVISER SEEKS COMPANIES THAT ARE DISCOUNTED DUE TO:
 .Company-specific problems that are over-discounted in the marketplace.
 .Cyclically out-of-favor status.
 .Unrecognized positive fundamentals.
 
 THE INVESTMENT ADVISER SEEKS TO IDENTIFY VALUE THROUGH:
 .Performing intensive, hands-on fundamental research.
 .Maintaining a long-term investment horizon.
 .A team approach to decision making.
 
 Value exists when a stock's price becomes inexpensive relative to the
 company's estimated earnings and/or dividend-paying ability over the long-
 term.
 
- --------------------------------------------------------------------------------
 
 GROWTH STYLE FUNDS
 
 
 Goldman Sachs' Growth Investment Philosophy:
 1. INVEST AS IF BUYING THE COMPANY/BUSINESS, NOT SIMPLY TRADING ITS STOCK:
 .Understand the business, management, products and competition.
 .Perform intensive, hands-on fundamental research.
 .Seek businesses with strategic competitive advantages.
 .Over the long-term, expect each company's stock price ultimately to track
  the growth of the business.
 
 
                                                                               1
<PAGE>
 
 
 2. BUY HIGH-QUALITY GROWTH BUSINESSES THAT POSSESS STRONG BUSINESS FRAN-
    CHISES, FAVORABLE LONG-TERM PROSPECTS AND EXCELLENT MANAGEMENT.
 
 3. PURCHASE SUPERIOR LONG-TERM GROWTH COMPANIES AT A FAVORABLE PRICE--SEEK
    TO PURCHASE AT A FAIR VALUATION, GIVING THE INVESTOR THE POTENTIAL TO
    FULLY CAPTURE RETURNS FROM ABOVE-AVERAGE GROWTH RATES.
 
 Growth companies have earnings expectations that exceed those of the stock
 market as a whole.
 
- --------------------------------------------------------------------------------
 
 QUANTITATIVE ("CORE") STYLE FUNDS
 
 
 Goldman Sachs' CORE Investment Philosophy:
 Goldman Sachs' quantitative style of funds--CORE--emphasizes the two build-
 ing blocks of active management: STOCK SELECTION and PORTFOLIO CONSTRUCTION.
 
 I. CORE Stock Selection
 The CORE Funds use the Goldman Sachs' proprietary multifactor model
 ("Multifactor Model"), a rigorous computerized rating system, to forecast
 the returns of securities held in each Fund's portfolio. The Multifactor
 Model incorporates common variables covering measures of:
 .VALUE (price-to-book, price-to-earnings, cash flow to enterprise value)
 .MOMENTUM (earnings momentum, price momentum, sustainable growth)
 .RISK (market risk, company-specific risk, earnings risk)
 .RESEARCH (fundamental research ratings of Goldman Sachs and other analysts)
 
 ALL OF THE ABOVE FACTORS ARE CAREFULLY EVALUATED WITHIN THE MULTIFACTOR
 MODEL SINCE EACH HAS DEMONSTRATED A SIGNIFICANT IMPACT ON THE PERFORMANCE OF
 THE SECURITIES AND MARKETS THEY WERE DESIGNED TO FORECAST. STOCK SELECTION
 IN THIS PROCESS COMBINES BOTH OUR QUANTITATIVE AND QUALITATIVE ANALYSIS.
 
 II. CORE Portfolio Construction
 A proprietary COMPUTER OPTIMIZER calculates every security combination (at
 every possible weighting) to CONSTRUCT THE MOST EFFICIENT RISK/RETURN PORT-
 FOLIO given each CORE Fund benchmark. In this process, the Investment
 Adviser manages risk by limiting deviations from the benchmark, running size
 and sector neutral portfolios.
 
 Goldman Sachs CORE Funds are fully invested, broadly diversified and offer
 consistent overall portfolio characteristics. They may serve as good founda-
 tions on which to build a portfolio.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 
 REAL ESTATE SECURITIES FUND
 
 
 Goldman Sachs' Real Estate Securities Investment Philosophy:
 When choosing the Fund's securities, the Investment Adviser:
 .Selects stocks based on quality of assets, experienced management and a
  sustainable competitive advantage.
 .Seeks to buy securities at a discount to the intrinsic value of the busi-
  ness (assets and management).
 .Seeks a team approach to decision making.
 
 Over time, REITs (which stand for Real Estate Investment Trusts) have
 offered investors important diversification and competitive total returns
 versus the broad equity market.

 Historically, stock and bond markets have often had different cycles, with
 one asset class rising when the other is falling. A balanced objective seeks
 to reduce the volatility associated with investing in a single market. There
 is no guarantee, however, that market cycles will move in opposition to one
 another or that a balanced investment program will successfully reduce vola-
 tility.
 
 Equity Securities. The Fund invests, under normal circumstances, between 45%
 and 65% of its total assets in equity securities. Although the Fund's equity
 investments consist primarily of publicly traded U.S. securities, the Fund
 may invest up to 10% of its total assets in the equity securities of foreign
 issuers, including issuers in countries with emerging markets or economies
 ("emerging countries") and equity securities quoted in foreign currencies.
 A portion of the Fund's portfolio of equity securities may be selected pri-
 marily to provide current income (includ-

 ing interests in REITs, convertible securities, preferred stocks, utility
 stocks, and interests in limited partnerships).
 
 Other. The Fund invests at least 25% of its total assets in fixed-income
 senior securities. The remainder of the Fund's assets are invested in other
 fixed-income securities and cash.
 
 The Fund's fixed-income securities primarily include:
 .Securities issued by the U.S. government, its agencies, instrumentalities
  or sponsored enterprises
 .Securities issued by corporations, banks and other issuers
 .Mortgage-backed and asset-backed securities
 
 The Fund may also invest up to 10% of its total assets in debt obligations
 (U.S. dollar and non-U.S.-dollar denominated) issued or guaranteed by one or
 more foreign governments or any of their political subdivisions, agencies or
 instrumentalities and foreign corporations or other entities. The issuers of
 these securities may be located in emerging countries.
 
 The percentage of the portfolio invested in equity and fixed-income securi-
 ties will vary from time to time as the Investment Adviser evaluates such
 securities' relative attractiveness based on market valuations, economic
 growth and inflation prospects. The allocation between equity and fixed-
 income securities is subject to the Fund's intention to pay regular quar-
 terly dividends. The amount of quarterly dividends can also be expected to
 fluctuate in accordance with factors such as prevailing interest rates and
 the percentage of the Fund's assets invested in fixed-income securities.

 The Fund seeks long-term growth of capital.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, at least
 65% of its total assets in equity securities of companies with public stock
 market capitalizations of $1 billion or less at the time of investment.
 Under normal circumstances, the Fund's investment horizon for ownership of
 stocks will be two to three years. Dividend income, if any, is an incidental
 consideration. If the market capitalization of a company held by the Fund
 increases above $1 billion, the Fund may, consistent with its investment
 objective, continue to hold the security.
 
 The Fund invests in companies which the Investment Adviser believes are
 well- managed niche businesses that have the potential to achieve high or
 improving returns on capital and/or above average sustainable growth. The
 Fund may invest in securities of small market capitalization companies which
 may have experienced financial difficulties. Investments may also be made in
 companies that are in the early stages of their life and that the Investment
 Adviser believes have significant growth potential. The Investment Adviser
 believes that the companies in which the Fund may invest offer greater
 opportunity for growth of capital than larger, more mature, better known
 companies. Although the Fund will invest primarily in publicly traded U.S.
 securities, it may invest up to 25% of its total assets in foreign securi-
 ties, including securities of issuers in emerging countries and securities
 quoted in foreign currencies.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 companies with public stock market capitalizations in excess of $1 billion
 at the time of investment and in fixed-income securities, such as corporate
 debt and bank obligations.

         Objective:   Total return comprised of long-term growth of capital
                      and dividend income
 
         Benchmark:   Wilshire Real Estate Securities Index
 
  Investment Focus:   REITs and real estate industry companies
 
  Investment Style:   Growth at a discount
 
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks total return comprised of long-term growth of capital and
 dividend income.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all and at least 80% of its total assets in a diversified portfolio
 of equity securities of issuers that are primarily engaged in or related to
 the real estate industry. The Fund expects that a substantial portion of its
 assets will be invested in REITs and real estate industry companies.
 
 A "real estate industry company" is a company that derives at least 50% of
 its gross revenues or net profits from the ownership, development, construc-
 tion, financing, management or sale of commercial, industrial or residential
 real estate or interests therein.
 
 The Fund's investment strategy is based on the premise that property market
 fundamentals are the primary determinant of growth, underlying the success
 of companies in the real estate industry. The Investment Adviser focuses on
 companies that can achieve sustainable growth in cash flow and dividend pay-
 ing capability. The Investment Adviser attempts to purchase securities so
 that its underlying portfolio will be diversified geographically and by
 property type. Although the Fund will invest primarily in publicly traded
 U.S. securities, it may invest up to 15% of its total assets in foreign
 securities, including securities of issuers in emerging countries and secu-
 rities quoted in foreign currencies.
 
 Investing in REITs involves certain unique risks in addition to those risks
 associated with investing in the real estate industry in general. Equity
 REITs may be affected by changes in the value of the underlying property
 owned by the REITs.

<PAGE>
 
                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
 Mortgage REITs may be affected by the quality of any credit extended. REITs
 are dependent upon management skill, may not be diversified, and are subject
 to heavy cash flow dependency, default by borrowers and self-liquidation.
 REITs are also subject to the possibilities of failing to qualify for tax
 free pass-through of income and failing to maintain their exemptions from
 investment company registration. REITs whose underlying properties are con-
 centrated in a particular industry or geographic region are also subject to
 risks affecting such industries and regions.
 
 REITs (especially mortgage REITs) are also subject to interest rate risks.
 When interest rates decline, the value of a REIT's investment in fixed rate
 obligations can be expected to rise. Conversely, when interest rates rise,
 the value of a REIT's investment in fixed rate obligations can be expected
 to decline. In contrast, as interest rates on adjustable rate mortgage loans
 are reset periodically, yields on a REIT's investment in such loans will
 gradually align themselves to reflect changes in market interest rates,
 causing the value of such investments to fluctuate less dramatically in
 response to interest rate fluctuations than would investments in fixed rate
 obligations.
 
 The REIT investments of the Real Estate Securities Fund often do not provide
 complete tax information to the Fund until after the calendar year-end. Con-
 sequently, because of the delay, it may be necessary for the Fund to request
 permission to extend the deadline for issuance of Forms 1099-DIV beyond Jan-
 uary 31.
 
 Other. The Fund may invest up to 20% of its total assets in fixed-income
 securities, such as corporate debt and bank obligations, that offer the
 potential to further the Fund's investment objective.
 
                                                                              17

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

All Funds:
 
 .CREDIT/DEFAULT RISK--The risk that an issuer of fixed-income securities held
 by a Fund (which may have low credit ratings) may default on its obligation to
 pay interest and repay principal.
 .FOREIGN RISKS--The risk that when a Fund invests in foreign securities, it
 will be subject to risk of loss not typically associated with domestic
 issuers. Loss may result because of less foreign government regulation, less
 public information and less economic, political and social stability. Loss may
 also result from the imposition of exchange controls, confiscations and other
 government restrictions. A Fund will also be subject to the risk of negative
 foreign currency rate fluctuations. Foreign risks will normally be greatest
 when a Fund invests in issuers located in emerging countries.
 .EMERGING COUNTRIES RISK--The securities markets of Asian, Latin American,
 Eastern European, African and other emerging countries are less liquid, are
 especially subject to greater price volatility, have smaller market capital-
 izations, have less government regulation and are not subject to as extensive
 and frequent accounting, financial and other reporting requirements as the
 securities markets of more developed countries. Further, investment in equity
 securities of issuers located in Russia and certain other emerging countries
 involves risk of loss resulting from problems in share registration and cus-
 tody and substantial economic and political disruptions. These risks are not
 normally associated with investment in more developed countries.
 .STOCK RISK--The risk that stock prices have historically risen and fallen in
 periodic cycles. As of the date of this Prospectus, U.S. stock markets and
 certain foreign stock markets were trading at or close to record high levels.
 There is no guarantee that such levels will continue.
 .DERIVATIVES RISK--The risk that loss may result from a Fund's investments in
 options, futures, swaps, structured securities and other derivative instru-
 ments. These instruments may be leveraged so that small changes may produce
 disproportionate losses to a Fund.
 .INTEREST RATE RISK--The risk that when interest rates increase, securities
 held by a Fund will decline in value. Long-term fixed-income securities will
 normally have more price volatility because of this risk than short-term secu-
 rities.
 .MANAGEMENT RISK--The risk that a strategy used by the Investment Adviser may
 fail to produce the intended results.
 .MARKET RISK--The risk that the value of the securities in which a Fund invests
 may go up or down in response to the prospects of individual companies and/or
 general economic conditions. Price changes may be temporary or last for
 extended periods.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 .LIQUIDITY RISK--The risk that a Fund will not be able to pay redemption pro-
 ceeds within the time period stated in this Prospectus because of unusual mar-
 ket conditions, an unusually high volume of redemption requests, or other rea-
 sons. Funds that invest in non-investment grade fixed-income securities, small
 capitalization stocks, REITs and emerging country issuers will be especially
 subject to the risk that during certain periods the liquidity of particular
 issuers or industries, or all securities within these investment categories,
 will shrink or disappear suddenly and without warning as a result of adverse
 economic, market or political events, or adverse investor perceptions whether
 or not accurate.
 .OTHER RISKS--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Specific Funds:
 
 .SMALL CAP STOCK AND REIT RISK--The securities of small capitalization stocks
 and REITs involve greater risks than those associated with larger, more estab-
 lished companies and may be subject to more abrupt or erratic price movements.
 Securities of such issuers may lack sufficient market liquidity to enable a
 Fund to effect sales at an advantageous time or without a substantial drop in
 price.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Service
 Shares from year to year; and (b) how the average annual returns of a Fund's
 Service Shares compare to those of broad-based securities market indices.
 The bar chart and table assume reinvestment of dividends and distributions.
 A Fund's past performance is not necessarily an indication of how the Fund
 will perform in the future. Performance reflects expense limitations in
 effect. If expense limitations were not in place, a Fund's performance would
 have been reduced. The CORE Large Cap Value and Real Estate Securities Funds
 did not commence operations until December 31, 1998 and July 27, 1998. The
 Strategic Growth and Growth Opportunities Funds had not commenced operations
 as of the date of this Prospectus. Since these Funds have less than one cal-
 endar year's performance, no performance information is provided in this
 section.

Fund Fees and Expenses continued
 
 
/1/The Funds' annual operating expenses have been restated to reflect current
fees, except for the CORE Large Cap Value, Strategic Growth, Growth Opportuni-
ties and Real Estate Securities Funds whose expenses are estimated for the cur-
rent fiscal year.
/2/The Investment Adviser has voluntarily agreed not to impose a portion of the
management fee on the CORE U.S. Equity Fund and the CORE Large Cap Growth Fund
equal to 0.05% and 0.15%, respectively, of such Funds' average daily net
assets. AS A RESULT OF FEE WAIVERS, THE CURRENT MANAGEMENT FEES OF THE CORE
U.S. EQUITY FUND AND CORE LARGE CAP GROWTH FUND ARE 0.70% AND 0.60%, RESPEC-
TIVELY, OF SUCH FUNDS' AVERAGE DAILY NET ASSETS. THE WAIVERS MAY BE TERMINATED
AT ANY TIME AT THE OPTION OF THE INVESTMENT ADVISER.
/3/Service Organizations may charge other fees to their customers who are bene-
ficial owners of Service Shares in connection with their customers' accounts.
Such fees may affect the return customers realize with respect to their invest-
ments.
/4/"Other Expenses" include transfer agency fees equal to 0.04% of the average
daily net assets of each Fund's Service Shares, plus all other ordinary
expenses not detailed above. The Investment Adviser has voluntarily agreed to
reduce or limit "Other Expenses" (excluding management fees, transfer agency
fees, service fees, taxes, interest and brokerage fees and litigation, indemni-
fication and other extraordinary expenses) to the following percentages of each
Fund's average daily net assets:

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in Service
Shares of a Fund for the time periods indicated and then redeem all of your
shares at the end of those periods. The Example also assumes that your invest-
ment has a 5% return each year and that a Fund's operating expenses remain the
same. Although your actual costs may be higher or lower, based on these assump-
tions your costs would be:

Service Organizations that invest in Service Shares on behalf of their custom-
ers may charge other fees directly to their customer accounts in connection
with their investments. You should contact your Service Organization for infor-
mation regarding such charges. Such fees, if any, may affect the return such
customers realize with respect to their investments.
 
Certain Service Organizations that invest in Service Shares may receive other
compensation in connection with the sale and distribution of service shares or
for services to their customers' accounts and/or the Funds. For additional
information regarding such compensation, see "Shareholder Guide" in the Pro-
spectus and "Other Information" in the Statement of Additional Information
("Additional Statement").

 GSAM is a separate operating division of Goldman Sachs, which registered as
 an investment adviser in 1981. GSFM, a registered investment adviser since
 1990, is a Delaware limited partnership which is an affiliate of Goldman
 Sachs. The Goldman Sachs Group, L.P., which controls the Investment Advis-
 ers, announced that it will pursue an initial public offering of the firm in
 the late spring or early summer of 1999. Simultaneously with the offering,
 the Goldman Sachs Group, L.P. will merge into The Goldman Sachs Group, Inc.
 As of February 28, 1999, GSAM and GSFM, together with their affiliates,
 acted as investment adviser or distributor for assets in excess of $199 bil-
 lion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser makes the investment decisions
 for the Funds and places purchase and sale orders for the Funds' portfolio
 transactions in U.S. and foreign markets. As permitted by applicable law,
 these orders may be directed to any brokers, including Goldman Sachs and its
 affiliates. While the Investment Adviser is ultimately responsible for the
 management of the Funds, it is able to draw upon the research and expertise
 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that a Fund
 could sustain losses during periods in which Goldman Sachs and its affili-
 ates and other accounts achieve significant profits on their trading for
 proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly
 
                                                                              47

 known as the "Year 2000 Problem"). To the extent these systems conduct for-
 ward-looking calculations, these computer problems may occur prior to Janu-
 ary 1, 2000. Like other investment companies and financial and business
 organizations, the Funds could be adversely affected in their ability to
 process securities trades, price securities, provide shareholder account
 services and otherwise conduct normal business operations if the Investment
 Adviser or other Fund service providers do not adequately address this prob-
 lem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
  .The Investment Adviser has established a dedicated group to analyze these
   issues and to implement the systems modifications necessary to prepare
   for the Year 2000 Problem.
  .The Investment Adviser has sought assurances from the Funds' other serv-
   ice providers that they are taking the steps necessary so that they do
   not experience Year 2000 Problems, and the Investment Adviser will con-
   tinue to monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.

Dividends
 
 
Each Fund pays dividends from its net investment income and distributions from
net realized capital gains. You may choose to have dividends and distributions
paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund. Spe-
 cial restrictions may apply for certain ILA Portfolios. See the Additional
 Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from net capital gains
are declared and paid as follows:

From time to time a portion of a Fund's dividends may constitute a return of
capital.
 
At the time of an investor's purchase of shares of a Fund, a portion of the NAV
per share may be represented by undistributed income or realized or unrealized
appreciation of the Fund's portfolio securities. Therefore, subsequent distri-
butions on such shares from such income or realized appreciation may be taxable
to the investor even if the NAV of the shares is, as a result of the distribu-
tions, reduced below the cost of such shares and the distributions (or portions
thereof) represent a return of a portion of the purchase price.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Service
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Service Shares Of The Funds?
 Generally, Service Shares may be purchased only through institutions that
 have agreed to provide account administration and personal and account main-
 tenance services to their customers who are the beneficial owners of Service
 Shares. These institutions are called "Service Organizations." Customers of
 a Service Organization will normally give their purchase instructions to the
 Service Organization, and the Service Organization will, in turn, place pur-
 chase orders with Goldman Sachs. Service Organizations will set times by
 which purchase orders and payments must be received by them from their cus-
 tomers. Generally, Service Shares may be purchased from the Funds on any
 business day at their net asset value ("NAV") next determined after receipt
 of an order by Goldman Sachs from a Service Organization. No sales load is
 charged. Purchases of Service Shares must be settled within three business
 days of receipt of a complete purchase order.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place an order with Goldman Sachs at 1-800-621-2550 and either:
 .Wire federal funds to The Northern Trust Company ("Northern"), as
  subcustodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian) on the next business day; OR
 .Initiate an Automated Clearing House Network ("ACH") transfer to Northern;
  OR
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Service Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 
                                                                              51
<PAGE>
 
 .Responding to inquiries from prospective and existing shareholders
 .Assisting customers with investment procedures
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of Goldman Sachs Trust (the "Trust"), purchase, redemption
 and exchange orders placed by or on behalf of their customers, and may des-
 ignate other intermediaries to accept such orders, if approved by the Trust.
 In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to a service plan adopted by the Trust's Board of Trustees, Service
 Organizations are entitled to receive payment for their services from the
 Trust of up to 0.50% (on an annualized basis) of the average daily net
 assets of the Service Shares of the Funds, which are attributable to or held
 in the name of the Service Organization for its customers.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 In addition to Service Shares, each Fund also offers other classes of shares
 to investors. These other share classes are subject to different fees and
 expenses (which affect performance), have different minimum investment
 requirements and
 are entitled to different services than Service Shares. Information regard-
 ing these other share classes may be obtained from your sales representative
 or from Goldman Sachs by calling the number on the back cover of this Pro-
 spectus.

 What Is My Minimum Investment In The Funds?
 The Funds do not have any minimum purchase or account requirements with
 respect to Service Shares. A Service Organization may, however, impose a
 minimum amount for initial and subsequent investments in Service Shares, and
 may establish other requirements such as a minimum account balance. A Serv-
 ice Organization may redeem Service Shares held by non-complying accounts,
 and may impose a charge for any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Reject or restrict any purchase or exchange orders by a particular pur-
  chaser (or group of related purchasers). This may occur, for example, when
  a pattern of frequent purchases, sales or exchanges of Service Shares of a
  Fund is evident, or if purchases, sales or exchanges are, or a subsequent
  abrupt redemption might be, of a size that would disrupt the management of
  a Fund.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Service Shares
 is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                    (Value of Assets of the Class)
                     - (Liabilities of the Class)
     NAV = _____________________________________________________
                 Number of Outstanding Shares of the Class
 
 The Funds' investments are valued based on market quotations or, if accurate
 quotations are not readily available, the fair value of the Fund's invest-
 ments may be determined in good faith under procedures established by the
 Trustees.
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will not be priced on any day
  the New York Stock Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form.
 
 NOTE: THE TIME AT WHICH TRANSACTIONS AND SHARES ARE PRICED AND THE TIME BY
 WHICH ORDERS MUST BE RECEIVED MAY BE CHANGED IN CASE OF AN EMERGENCY OR IF
 
                                                                              53
<PAGE>
 
 REGULAR TRADING ON THE NEW YORK STOCK EXCHANGE IS STOPPED AT A TIME OTHER
 THAN 4:00 P.M. NEW YORK TIME.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 In addition, the impact of events that occur after the publication of market
 quotations used by a Fund to price its securities but before the close of
 regular trading on the New York Stock Exchange will normally not be
 reflected in a Fund's next determined NAV unless the Trust, in its discre-
 tion, makes an adjustment in light of the nature and materiality of the
 event, its effect on Fund operations and other relevant factors.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Service Shares Of The Funds?
 Generally, Service Shares may be sold (redeemed) only through Service Orga-
 nizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. GENERALLY,
 EACH FUND WILL REDEEM ITS SERVICE SHARES UPON REQUEST ON ANY BUSINESS DAY AT
 THEIR NAV NEXT DETERMINED AFTER RECEIPT OF SUCH REQUEST IN PROPER FORM.
 Redemption proceeds may be sent to recordholders by check or by wire (if the
 wire instructions are on record).
 
 A Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is elected on the Account
 Application.

 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to

                                                               SHAREHOLDER GUIDE
 
 confirm that such instructions are genuine. If reasonable procedures are not
 employed, the Trust may be liable for any loss due to unauthorized or fraud-
 ulent transactions. The following general policies are currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 NOTE: IT MAY BE DIFFICULT TO MAKE TELEPHONE REDEMPTIONS IN TIMES OF DRASTIC
 ECONOMIC OR MARKET CONDITIONS.
 
 How Are Redemption Proceeds Paid?
 BY WIRE: The Funds will arrange for redemption proceeds to be wired as fed-
 eral funds to the bank account designated in the recordholder's Account
 Application. The following general policies govern wiring redemption pro-
 ceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If the shares to be sold were recently paid for by
  check, the Fund will pay the redemption proceeds when the check has
  cleared, which may take up to 15 days. If the Federal Reserve Bank is
  closed on the day that the redemption proceeds would ordinarily be wired,
  wiring the redemption proceeds may be delayed one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  Account Application to the Service Organization.
 .Neither the Trust, nor Goldman Sachs assume any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organization.
 
 BY CHECK: A recordholder may elect in writing to receive redemption proceeds
 by check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of receipt of a properly exe-
 cuted redemption request. If the shares to be sold were recently paid for by
 check, the Fund will pay the redemption proceeds when the check has cleared,
 which may take up to 15 days.

 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem the Service Shares of any Service Organization whose account balance
  falls below $50 as a result of a redemption. The Funds will not redeem
  Service Shares on this basis if the value of the account falls below the
  minimum account balance solely as a result of market conditions. The Fund
  will give 60 days' prior written notice to allow a Service Organization to
  purchase sufficient additional shares of the Fund in order to avoid such
  redemption.
 .Redeem the shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Service Shares of a Fund at NAV for
 Service Shares of any other Goldman Sachs Fund. The exchange privilege may
 be materially modified or withdrawn at any time upon 60 days' written
 notice.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirement of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will Be Sent Regarding Investments In Service Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Service Organizations
 will also be provided with a printed confirmation for each transaction in
 their account and a monthly account statement. Service Organizations are
 responsible for providing these or other reports to their customers who are
 the beneficial owners of Service Shares in accordance with the rules that
 apply to their accounts with the Service Organizations.

Taxation
 
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Fund distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Fund's net investment income, certain net realized
 foreign exchange gains and net short-term capital gains. They are taxable as
 long-term capital gains to the extent they are attributable to the Fund's
 excess of net long-term capital gains over net short-term capital losses.
 The tax status of any distribution is the same regardless of how long you
 have been in the Fund and whether you reinvest in additional shares or take
 the distribution as cash. Certain distributions paid by a Fund in January of
 a given year may be taxable to shareholders as if received the prior Decem-
 ber 31. The tax status and amounts of the distributions for each calendar
 year will be detailed in your annual tax statement from the Fund.
 
 A Fund's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Fund receives from U.S. domestic
 corporations may be eligible, in the hands of the corporate shareholders,
 for the corporate dividends-received deduction, subject to certain holding
 period requirements and debt financing limitations.
 
 Each Fund may be subject to foreign withholding or other foreign taxes on
 income or gain from certain foreign securities. In general, the Funds may
 deduct these taxes in computing their taxable income.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In its efforts to adhere to these requirements, the
 Funds may have to limit their investment activity in some types of instru-
 ments.

 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements for the periods that you hold shares.) Any loss rec-
 ognized on shares held for six months or less will be treated as a long-term
 capital loss to the extent of any capital gain dividends that were received
 with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from a Fund or on the value of the shares
 held by you. More tax information is provided in the Additional Statement.
 You should also consult your own tax adviser for information regarding all
 tax consequences applicable to your investments in the Funds.

Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 
 A. General Portfolio Risks
 
 The Funds will be subject to the risks associated with equity securities.
 "Equity securities" include common stocks, preferred stocks, interests in
 real estate investment trusts, convertible debt obligations, convertible
 preferred stocks, equity interests in trusts, partnerships, joint ventures,
 limited liability companies and similar enterprises, warrants and stock pur-
 chase rights. In general, stock values fluctuate in response to the activi-
 ties of individual companies and in response to general market and economic
 conditions. Accordingly, the value of the stocks that a Fund holds may
 decline over short or extended periods. The stock markets tend to be cycli-
 cal, with periods when stock prices generally rise and periods when prices
 generally decline. The volatility of equity securities means that the value
 of your investment in the Funds may increase or decrease. As of the date of
 this Prospectus, certain stock markets were trading at or close to record
 high levels and there can be no guarantee that such levels will continue.
 
 To the extent that a Fund invests in fixed-income securities, that Fund will
 also be subject to the risks associated with its fixed-income securities.
 These risks include interest rate risk, credit risk and call/extension risk.
 In general, interest rate risk involves the risk that when interest rates
 decline, the market value of fixed-income securities tends to increase. Con-
 versely, when interest rates increase, the market value of fixed-income
 securities tends to decline. Credit risk involves the risk that an issuer
 could default on its obligations, and a Fund will not recover its invest-
 ment. Call risk and extension risk are normally present in mortgage-backed
 securities and asset-backed securities. For example, homeowners have the
 option to prepay their mortgages. Therefore, the duration of a security
 backed by home mortgages can either shorten (call risk) or lengthen (exten-
 sion risk). In general, if interest rates on new mortgage loans fall suffi-
 ciently below the interest rates on existing outstanding mortgage loans, the
 rate of prepayment would be expected to increase. Conversely, if mortgage
 loan interest rates rise above the interest rates on existing outstanding
 mortgage loans, the rate of prepayment would be expected to decrease. In
 either case, a change in the prepayment rate can result in losses to invest-
 ors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by

                                                                      APPENDIX A
 
 dividing the lesser of the dollar amount of sales or purchases of portfolio
 securities by the average monthly value of a Fund's portfolio securities,
 excluding securities having a maturity at the date of purchase of one year
 or less. See "Financial Highlights" in Appendix B for a statement of the
 Funds' historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all investment objectives and policies not specifically designated as
 fundamental are non-fundamental and may be changed without shareholder
 approval. If there is a change in a Fund's investment objective, you should
 consider whether that Fund remains an appropriate investment in light of
 your then current financial position and needs.
 
 B. Other Portfolio Risks
 
 
 RISKS OF INVESTING IN SMALL CAPITALIZATION COMPANIES AND REITS. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such securities. Small capitalization companies
 and REITs may be thinly traded and may have to be sold at a discount from
 current market prices or in small lots over an extended period of time. In
 addition, these securities are subject to the risk that during certain peri-
 ods the liquidity of particular issuers or industries, or all securities in
 these investment categories, will shrink or disappear suddenly and without
 warning as a result of adverse economic or market conditions, or adverse
 investor perceptions whether or not accurate. Because of the lack of suffi-
 cient market liquidity, a Fund may incur losses because it will be required
 to effect sales at a disadvantageous time and only then at a substantial
 drop in price. Small capitalization companies and REITs include "unseasoned"
 issuers that do not have an established financial history; often have lim-
 ited product lines, markets or financial resources; may depend on or use a
 few key personnel for management; and may be susceptible to losses and risks
 of bankruptcy. Transaction costs for these investments are often higher than
 those of larger capitalization companies. Investments in small capitaliza-
 tion companies and REITs may be more difficult to price precisely than other
 types of securities because of their characteristics and lower trading vol-
 umes.
 
 
                                                                              61
<PAGE>
 
 
 RISKS OF FOREIGN INVESTMENTS. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts after January 1, 1999 that refer to existing currencies
 rather than the euro; the establishment and maintenance of exchange rates
 for currencies being converted into the euro; the fluctuation of the euro
 relative to non-euro currencies during the transition period from January 1,
 1999 to December 31, 2001 and beyond; whether the interest rate, tax and
 labor regimes of European countries participating in the euro will converge
 over time; and whether the conversion of the currencies of other countries
 that now are or may in the future become members of the European Union
 ("EU"), may have an impact on the euro. These or other factors, including
 political and economic risks, could cause market disruptions, and could
 adversely affect the value of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Efforts in foreign countries to remediate potential Year

                                                                      APPENDIX A
 
 2000 problems are not as extensive as those in the United States. As a
 result, the operations of foreign markets, foreign issuers and foreign gov-
 ernments may be disrupted by the Year 2000 Problem, and the investment port-
 folio of a Fund may be adversely affected. Furthermore, with respect to cer-
 tain foreign countries, there is a possibility of nationalization,
 expropriation or confiscatory taxation, imposition of withholding or other
 taxes on dividend or interest payments (or, in some cases, capital gains),
 limitations on the removal of funds or other assets of the Funds, and polit-
 ical or social instability or diplomatic developments which could affect
 investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such debt, and a Fund may have limited recourse to compel
 payment in the event of a default. Periods of economic uncertainty may
 result in the volatility of market prices of sovereign debt, and in turn a
 Fund's NAV, to a greater extent than the volatility inherent in debt obliga-
 tions of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Funds may also invest in European Depository
 Receipts ("EDRs") or other similar instruments representing securities of
 foreign issuers. ADRs represent the right to receive securities of foreign
 issuers deposited in a domestic bank or a correspondent bank. Prices of ADRs
 are quoted in U.S. dollars, and ADRs are traded in the United States. EDRs
 and GDRs are receipts evidencing an arrangement with a non-U.S. bank. EDRs
 and GDRs are not necessarily quoted in the same currency as the underlying
 security.
 
 RISKS OF EMERGING COUNTRIES. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are gener-
 
                                                                              63

 ally located in the Asia-Pacific region, Eastern Europe, Latin and South
 America and Africa. A Fund's purchase and sale of portfolio securities in
 certain emerging countries may be constrained by limitations as to daily
 changes in the prices of listed securities, periodic trading or settlement
 volume and/or limitations on aggregate holdings of foreign investors. Such
 limitations may be computed based on the aggregate trading volume by or
 holdings of a Fund, the Investment Adviser, its affiliates and their respec-
 tive clients and other service providers. A Fund may not be able to sell
 securities in circumstances where price, trading or settlement volume limi-
 tations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, it is anticipated that
 a Fund may invest in such countries through other investment funds in such
 countries.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and
 
64
<PAGE>
 
                                                                      APPENDIX A
 
 ethnic, religious and racial disaffection, among other factors, have also
 led to social unrest, violence and/or labor unrest in some emerging coun-
 tries. Unanticipated political or social developments may result in sudden
 and significant investment losses. Investing in emerging countries involves
 greater risk of loss due to expropriation, nationalization, confiscation of
 assets and property or the imposition of restrictions on foreign investments
 and on repatriation of capital invested.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Fund in emerging countries may not be as sound as the
 creditworthiness of firms used in more developed countries. As a result, the
 Fund may be subject to a greater risk of loss if a securities firm defaults
 in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than investments in countries with more developed securities mar-
 kets (such as the United States, Japan and most Western European countries).
 A Fund's investments in emerging countries are subject to the risk that the
 liquidity of a particular investment, or investments generally, in such
 countries will shrink or disappear suddenly and without warning as a result
 of adverse economic, market or political conditions or adverse investor per-
 ceptions, whether or not accurate. Because of the lack of sufficient market
 liquidity, a Fund may incur losses because it will be required to effect
 sales at a disadvantageous time and only then at a substantial drop in
 price. Investments in emerging countries may be more difficult to price pre-
 cisely because of the characteristics discussed above and lower trading vol-
 umes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.
 
                                                                              65
<PAGE>
 
 
 
 RISKS OF DERIVATIVE INVESTMENTS. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities and currency transactions involve additional risk of
 loss. Loss can result from a lack of correlation between changes in the
 value of derivative instruments and the portfolio assets (if any) being
 hedged, the potential illiquidity of the markets for derivative instruments,
 or the risks arising from margin requirements and related leverage factors
 associated with such transactions. The use of these management techniques
 also involves the risk of loss if the Investment Adviser is incorrect in its
 expectation of fluctuations in securities prices, interest rates or currency
 prices. Each Fund may also invest in derivative investments for non-hedging
 purposes (that is, to seek to increase total return). Investing for non-
 hedging purposes is considered a speculative practice and presents even
 greater risk of loss.
 
 RISKS OF ILLIQUID SECURITIES. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of
  more than seven days
 .Certain over-the-counter options
 .Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that such
  restricted security is eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 CREDIT RISKS. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Further informa-
 tion is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse

<PAGE>
 
                                                                      APPENDIX A
 
 economic conditions or changing circumstances may weaken their issuers'
 capacity to pay interest and repay principal. A security will be deemed to
 have met a rating requirement if it receives the minimum required rating
 from at least one such rating organization even though it has been rated
 below the minimum rating by one or more other rating organizations, or if
 unrated by such rating organizations, determined by the Investment Adviser
 to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 TEMPORARY INVESTMENT RISKS. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 .U.S. government securities
 .Commercial paper rated at least A-2 by Standard & Poor's or P-2 by Moody's
 .Certificates of deposit
 .Bankers' acceptances
 .Repurchase agreements
 .Non-convertible preferred stocks and non-convertible corporate bonds with a
  remaining maturity of less than one year
 
 When a Fund's assets are invested in such instruments, the Fund may not be
 achieving its investment objective.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 CONVERTIBLE SECURITIES. Each Fund may invest in convertible securities. Con-
 vertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which
 
                                                                              67

 a Fund invests are subject to the same rating criteria as its other invest-
 ments in fixed-income securities. Convertible securities have both equity
 and fixed-income risk characteristics. Like all fixed-income securities, the
 value of convertible securities is susceptible to the risk of market losses
 attributable to changes in interest rates. Generally, the market value of
 convertible securities tends to decline as interest rates increase and, con-
 versely, to increase as interest rates decline. However, when the market
 price of the common stock underlying a convertible security exceeds the con-
 version price of the convertible security, the convertible security tends to
 reflect the market price of the underlying common stock. As the market price
 of the underlying common stock declines, the convertible security, like a
 fixed-income security, tends to trade increasingly on a yield basis, and
 thus may not decline in price to the same extent as the underlying common
 stock.
 
 FOREIGN CURRENCY TRANSACTIONS. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, certain Funds may also
 enter into such transactions to seek to increase total return, which is con-
 sidered a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in connection with investments in foreign securities when, in the
 judgment of the Investment Adviser, it would be beneficial to convert such
 currency into U.S. dollars at a later date (e.g., the Investment Adviser may
 anticipate the foreign currency to appreciate against the U.S. dollar).
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the

                                                                      APPENDIX A
 
 counterparty to the contract will default on its obligations. Since these
 contracts are not guaranteed by an exchange or clearinghouse, a default on a
 contract would deprive a Fund of unrealized profits, transaction costs or
 the benefits of a currency hedge or could force the Fund to cover its pur-
 chase or sale commitments, if any, at the current market price.
 
 STRUCTURED SECURITIES. Each Fund may invest in structured securities. Struc-
 tured securities are securities whose value is determined by reference to
 changes in the value of specific currencies, interest rates, commodities,
 indices or other financial indicators (the "Reference") or the relative
 change in two or more References. The interest rate or the principal amount
 payable upon maturity or redemption may be increased or decreased depending
 upon changes in the applicable Reference. Structured securities may be posi-
 tively or negatively indexed, so that appreciation of the Reference may pro-
 duce an increase or decrease in the interest rate or value of the security
 at maturity. In addition, changes in the interest rates or the value of the
 security at maturity may be a multiple of changes in the value of the Refer-
 ence. Consequently, structured securities may present a greater degree of
 market risk than other types of fixed-income securities and may be more vol-
 atile, less liquid and more difficult to price accurately than less complex
 securities.
 
 REITS. Each Fund may invest in REITS. REITS are pooled investment vehicles
 that invest primarily in either real estate or real estate related loans.
 The value of a REIT is affected by changes in the value of the properties
 owned by the REIT or securing mortgage loans held by the REIT. REITs are
 dependent upon the ability of the REITs' managers, and are subject to heavy
 cash flow dependency, default by borrowers and the qualification of the
 REITs under applicable regulatory requirements for favorable income tax
 treatment. REITs are also subject to risks generally associated with invest-
 ments in real estate including possible declines in the value of real
 estate, general and local economic conditions, environmental problems and
 changes in interest rates. To the extent that assets underlying a REIT are
 concentrated geographically, by property type or in certain other respects,
 these risks may be heightened. A Fund will indirectly bear its proportionate
 share of any expenses, including management fees, paid by a REIT in which it
 invests.
 
 OPTIONS ON SECURITIES, SECURITIES INDICES AND FOREIGN CURRENCIES. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which they may invest or on
 
                                                                              69
<PAGE>
 
 
 any securities index comprised of securities in which they may invest. A
 Fund may also, to the extent that it invests in foreign securities, purchase
 and sell (write) put and call options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater illiquidity and credit risks.
 
 FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 government securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their term structures, sector selec-
 tion and durations in accordance with their investment objectives and poli-
 cies. Each Fund may also enter into closing purchase and sale transactions
 with respect to such contracts and options. A Fund will engage in futures
 and related options transactions for bona fide hedging purposes as defined
 in regulations of the Commodity Futures Trading Commission or to seek to
 increase total return to the extent permitted by such regulations. A Fund
 may not purchase or sell futures contracts or purchase or sell related
 options to seek to increase total return, except for closing purchase or
 sale transactions, if immediately thereafter the sum of the amount of ini-
 tial margin deposits and premiums

                                                                      APPENDIX A
 
 paid on the Fund's outstanding positions in futures and related options
 entered into for the purpose of seeking to increase total return would
 exceed 5% of the market value of the Fund's net assets.
 
 Futures contracts and related options present the following risks:
 .While a Fund may benefit from the use of futures and options on futures,
  unanticipated changes in interest rates, securities prices or currency
  exchange rates may result in poorer overall performance than if the Fund
  had not entered into any futures contracts or options transactions.
 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and a Fund may be exposed to additional risk
  of loss.
 .The loss incurred by a Fund in entering into futures contracts and in writ-
  ing call options on futures is potentially unlimited and may exceed the
  amount of the premium received.
 .Futures markets are highly volatile and the use of futures may increase the
  volatility of a Fund's NAV.
 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to a Fund.
 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.
 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 EQUITY SWAPS. Each Fund may invest in equity swaps. Equity swaps allow the
 parties to a swap agreement to exchange the dividend income or other compo-
 nents of return on an equity investment (for example, a group of equity
 securities or an index) for a component of return on another non-equity or
 equity investment.
 
 An equity swap may be used by a Fund to invest in a market without owning or
 taking physical custody of securities in circumstances in which direct
 investment may be restricted for legal reasons or is otherwise impractical.
 Equity swaps are derivatives and their value can be very volatile. To the
 extent that the Investment Adviser does not accurately analyze and predict
 the potential relative fluctuation of the components swapped with another
 party, a Fund may suffer a loss. The value of some components of an equity
 swap (such as the dividends on a common stock) may also be sensitive to
 changes in interest rates. Furthermore, a Fund may suffer a loss if the
 counterparty defaults.
 
 WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS. Each Fund may purchase when-
 issued securities and make contracts to purchase or sell securities for a
 fixed price at a future date beyond customary settlement time. When-issued
 securities are securities that have been authorized, but not yet issued.
 When-issued securities are purchased in order to secure what is considered
 to be an advantageous price and yield to the Fund at the time
 
                                                                              71
<PAGE>
 
 
 of entering into the transaction. A forward commitment involves the entering
 into a contract to purchase or sell securities for a fixed price at a future
 date beyond the customary settlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 REPURCHASE AGREEMENTS. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with primary dealers in U.S. government securities and member banks of the
 Federal Reserve System which furnish collateral at least equal in value or
 market price to the amount of their repurchase obligation.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's costs associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Certain
 Funds, together with other registered investment companies having advisory
 agreements with the Investment Adviser or any of its affiliates, may trans-
 fer uninvested cash balances into a single joint account, the daily aggre-
 gate balance of which will be invested in one or more repurchase agreements.
 
 LENDING OF PORTFOLIO SECURITIES. Each Fund may engage in securities lending.
 Securities lending involves the lending of securities owned by a Fund to
 financial institutions such as certain broker-dealers. The borrowers are
 required to secure their loan continuously with cash, cash equivalents, U.S.
 government securities or letters of credit in an amount at least equal to
 the market value of the securities loaned. Cash collateral may be invested
 in cash equivalents. If the Investment Adviser determines to make securities
 loans, the value of the securities loaned may not exceed 33 1/3% of the
 value of the total assets of a Fund (including the loan collateral).

                                                                      APPENDIX A
 
 
 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 SHORT SALES AGAINST-THE-BOX. Certain Funds may make short sales against-the-
 box. A short sale against-the-box means that at all times when a short posi-
 tion is open the Fund will own an equal amount of securities sold short, or
 securities convertible into or exchangeable for, without payment of any fur-
 ther consideration, an equal amount of the securities of the same issuer as
 the securities sold short.
 
 PREFERRED STOCK, WARRANTS AND RIGHTS. Each Fund may invest in preferred
 stock, warrants and rights. Preferred stocks are securities that represent
 an ownership interest providing the holder with claims on the issuer's earn-
 ings and assets before common stock owners but after bond owners. Unlike
 debt securities, the obligations of an issuer of preferred stock, including
 dividend and other payment obligations, may not typically be accelerated by
 the holders of such preferred stock on the occurrence of an event of default
 or other non-compliance by the issuer of the preferred stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.
 
 OTHER INVESTMENT COMPANIES. Each Fund may invest in securities of other
 investment companies (including SPDRs and WEBs, as defined below) subject to
 statutory limitations prescribed by the Act. These limitations include a
 prohibition on any Fund acquiring more than 3% of the voting shares of any
 other investment company, and a prohibition on investing more than 5% of a
 Fund's total assets in securities of any one investment company or more than
 10% of its total assets in securities of all investment companies. A Fund
 will indirectly bear its proportionate share of any management fees and
 other expenses paid by such other investment companies. Such other invest-
 ment companies will have investment objectives, policies and restrictions
 substantially similar to those of the acquiring Fund and will be subject to
 substantially the same risks.
 
 .STANDARD & POOR'S DEPOSITORY RECEIPTS. The Funds may, consistent with their
  investment policies, purchase Standard & Poor's Depository Receipts
  ("SPDRs"). SPDRs are securities traded on the American Stock Exchange
  ("AMEX") that represent ownership in the SPDR Trust, a trust which has been
  established to accumulate and hold a portfolio of common stocks that is
  intended to track the price performance and dividend yield of the S&P 500.
  The SPDR Trust is sponsored by a subsidiary of the AMEX. SPDRs may be used
  for several reasons, including, but not limited to, facilitating the han-
  dling of cash
 
                                                                              73
<PAGE>
 
 
  flows or trading, or reducing transaction costs. The price movement of
  SPDRs may not perfectly parallel the price action of the S&P 500.
 
 .WORLD EQUITY BENCHMARK SHARES. World Equity Benchmark Shares ("WEBS") are
  shares of an investment company that invests substantially all of its
  assets in securities included in the MSCI indices for specified countries.
  WEBS are listed on the AMEX and were initially offered to the public in
  1996. The market prices of WEBS are expected to fluctuate in accordance
  with both changes in the NAVs of their underlying indices and supply and
  demand of WEBS on the AMEX. To date, WEBS have traded at relatively modest
  discounts and premiums to their NAVs. However, WEBS have a limited operat-
  ing history and information is lacking regarding the actual performance and
  trading liquidity of WEBS for extended periods or over complete market
  cycles. In addition, there is no assurance that the requirements of the
  AMEX necessary to maintain the listing of WEBS will continue to be met or
  will remain unchanged. In the event substantial market or other disruptions
  affecting WEBS should occur in the future, the liquidity and value of a
  Fund's shares could also be substantially and adversely affected. If such
  disruptions were to occur, a Fund could be required to reconsider the use
  of WEBS as part of its investment strategy.
 
 UNSEASONED COMPANIES. Each Fund may invest in companies (including predeces-
 sors) which have operated less than three years, except that this limitation
 does not apply to debt securities which have been rated investment grade or
 better by at least one NRSRO. The securities of such companies may have lim-
 ited liquidity, which can result in their being priced higher or lower than
 might otherwise be the case. In addition, investments in unseasoned compa-
 nies are more speculative and entail greater risk than do investments in
 companies with an established operating record.
 
 CORPORATE DEBT OBLIGATIONS. Corporate debt obligations include bonds, notes,
 debentures and other obligations of corporations to pay interest and repay
 principal, and include securities issued by banks and other financial insti-
 tutions. Each Fund may invest in corporate debt obligations issued by U.S.
 and certain non-U.S. issuers which issue securities denominated in the U.S.
 dollar (including Yankee and Euro obligations). In addition to obligations
 of corporations, corporate debt obligations include securities issued by
 banks and other financial institutions and supranational entities (i.e., the
 World Bank, the International Monetary Fund, etc.).
 
 BANK OBLIGATIONS. Each Fund may invest in obligations issued or guaranteed
 by U.S. or foreign banks. Bank obligations, including without limitations,
 time deposits, bankers' acceptances and certificates of deposit, may be gen-
 eral obligations of the parent bank or may be limited to the issuing branch
 by the terms of the specific obligations or by government regulations. Banks
 are subject to extensive but

                                                                      APPENDIX A
 
 different governmental regulations which may limit both the amount and types
 of loans which may be made and interest rates which may be charged. In addi-
 tion, the profitability of the banking industry is largely dependent upon
 the availability and cost of funds for the purpose of financing lending
 operations under prevailing money market conditions. General economic condi-
 tions as well as exposure to credit losses arising from possible financial
 difficulties of borrowers play an important part in the operation of this
 industry.
 
 U.S. GOVERNMENT SECURITIES AND RELATED CUSTODIAL RECEIPTS. Each Fund may
 invest in U.S. government securities and related custodial receipts. U.S.
 government securities include U.S. Treasury obligations and obligations
 issued or guaranteed by U.S. government agencies, instrumentalities or spon-
 sored enterprises. U.S. government securities may be supported by (a) the
 full faith and credit of the U.S. Treasury (such as the Government National
 Mortgage Association ("Ginnie Mae")); (b) the right of the issuer to borrow
 from the U.S. Treasury (such as securities of the Student Loan Marketing
 Association); (c) the discretionary authority of the U.S. government to pur-
 chase certain obligations of the issuer (such as the Federal National Mort-
 gage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. government
 securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. government securities, where the interest and principal compo-
 nents of stripped U.S. government securities are traded independently.
 
 Interests in U.S. government securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S.
 government.
 
 MORTGAGE-BACKED SECURITIES. Certain Funds may invest in mortgage-backed
 securities. Mortgage-backed securities represent direct or indirect partici-
 pations in, or are collateralized by and payable from, mortgage loans
 secured by real property. Mortgage-backed securities can be backed by either
 fixed rate mortgage loans or adjustable rate mortgage loans, and may be
 issued by either a governmental or non-governmental entity. Privately issued
 mortgage-backed securities are normally structured with one or more types of
 "credit enhancement." However, these mortgage-backed securities typically do
 not have the same credit standing as U.S. government guaranteed mortgage-
 backed securities.
 
 Mortgage-backed securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an
 
                                                                              75
<PAGE>
 
 
 investor with a specified interest in the cash flow from a pool of under-
 lying mortgages or of other mortgage-backed securities. CMOs are issued in
 multiple classes. In most cases, payments of principal are applied to the
 CMO classes in the order of their respective stated maturities, so that no
 principal payments will be made on a CMO class until all other classes hav-
 ing an earlier stated maturity date are paid in full. A REMIC is a CMO that
 qualifies for special tax treatment and invests in certain mortgages princi-
 pally secured by interests in real property and other permitted investments.
 
 Mortgaged-backed securities also include stripped mortgage-backed securities
 ("SMBS"), which are derivative multiple class mortgage-backed securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other mortgage-backed securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 ASSET-BACKED SECURITIES. Certain Funds may invest in asset-backed securi-
 ties. Asset-backed securities are securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed securities are often subject to more rapid repayment than their
 stated maturity date would indicate as a result of the pass-through of pre-
 payments of principal on the underlying loans. During periods of declining
 interest rates, prepayment of loans underlying asset-backed securities can
 be expected to accelerate. Accordingly, a Fund's ability to maintain posi-
 tions in such securities will be affected by reductions in the principal
 amount of such securities resulting from prepayments, and its ability to
 reinvest the returns of principal at comparable yields is subject to gener-
 ally prevailing interest rates at that time. Asset-backed securities present
 credit risks that are not presented by mortgage-backed securities. This is
 because asset-backed securities generally do not have the benefit of a secu-
 rity interest in collateral that is comparable to mortgage assets. There is
 the possibility that, in some cases, recoveries on repossessed collateral
 may not be available to support payments on these securities. In the event
 of a default, a Fund may suffer a loss if it cannot sell collateral quickly
 and receive the amount it is owed.
 
 BORROWINGS. Each Fund can borrow money from banks and other financial insti-
 tutions in amounts not exceeding one-third of their total assets for tempo-
 rary or emergency purposes. A Fund may not make additional investments if
 borrowings exceed 5% of its total assets.

                                                                      APPENDIX A
 
 
 MORTGAGE DOLLAR ROLLS. Certain Funds may enter into mortgage dollar rolls. A
 mortgage dollar roll involves the sale by a Fund of securities for delivery
 in the current month. The Fund simultaneously contracts with the same
 counterparty to repurchase substantially similar (same type, coupon and
 maturity) but not identical securities on a specified future date. During
 the roll period, the Fund loses the right to receive principal and interest
 paid on the securities sold. However, the Fund benefits to the extent of any
 difference between (a) the price received for the securities sold and (b)
 the lower forward price for the future purchase and/or fee income plus the
 interest earned on the cash proceeds of the securities sold. Unless the ben-
 efits of a mortgage dollar roll exceed the income, capital appreciation and
 gain or loss due to mortgage prepayments that would have been realized on
 the securities sold as part of the roll, the use of this technique will
 diminish the Fund's performance.
 
 Successful use of mortgage dollar rolls depends upon the Investment Advis-
 er's ability to predict correctly interest rates and mortgage prepayments.
 If the Investment Adviser is incorrect in its prediction, a Fund may experi-
 ence a loss. For financial reporting and tax purposes, the Funds treat mort-
 gage dollar rolls as two separate transactions: one involving the purchase
 of a security and a separate transaction involving a sale. The Funds do not
 currently intend to enter into mortgage dollar rolls that are accounted for
 as a financing and do not treat them as borrowings.
 
 YIELD CURVE OPTIONS. Certain Funds may enter into options on the yield
 "spread" or differential between two securities. Such transactions are
 referred to as "yield curve" options. In contrast to other types of options,
 a yield curve option is based on the difference between the yields of desig-
 nated securities, rather than the prices of the individual securities, and
 is settled through cash payments. Accordingly, a yield curve option is prof-
 itable to the holder if this differential widens (in the case of a call) or
 narrows (in the case of a put), regardless of whether the yields of the
 underlying securities increase or decrease.
 
 The trading of yield curve options is subject to all of the risks associated
 with the trading of other types of options. In addition, such options pres-
 ent a risk of loss even if the yield of one of the underlying securities
 remains constant, or if the spread moves in a direction or to an extent
 which was not anticipated.
 
 REVERSE REPURCHASE AGREEMENTS. Certain Funds may enter into reverse repur-
 chase agreements. Reverse repurchase agreements involve the sale of securi-
 ties held by a Fund subject to the Fund's agreement to repurchase them at a
 mutually agreed upon date and price (including interest). These transactions
 may be entered into as a temporary measure for emergency purposes or to meet
 redemption requests. Reverse repurchase agreements may also be entered into
 when the Invest-
 
                                                                              77
<PAGE>
 
 
 ment Adviser expects that the interest income to be earned from the invest-
 ment of the transaction proceeds will be greater than the related interest
 expense. Reverse repurchase agreements involve leveraging. If the securities
 held by a Fund decline in value while these transactions are outstanding,
 the NAV of the Fund's outstanding shares will decline in value by propor-
 tionately more than the decline in value of the securities. In addition,
 reverse repurchase agreements involve the risk that the interest income
 earned by a Fund (from the investment of the proceeds) will be less than the
 interest expense of the transaction, that the market value of the securities
 sold by a Fund will decline below the price the Fund is obligated to pay to
 repurchase the securities, and that the securities may not be returned to
 the Fund.
 
 MUNICIPAL SECURITIES. Certain Funds may invest in securities and instruments
 issued by state and local government issuers. Municipal securities in which
 a Fund may invest consist of bonds, notes, commercial paper and other
 instruments (including participating interest in such securities) issued by
 or on behalf of states, territories and possessions of the United States
 (including the District of Columbia) and their political subdivisions, agen-
 cies or instrumentalities. Such securities may pay fixed, variable or float-
 ing rates of interest. Municipal securities are often issued to obtain funds
 for various public purposes, including the construction of a wide range of
 public facilities such as bridges, highways, housing, hospitals, mass trans-
 portation, schools, streets and water and sewer works. Other public purposes
 for which municipal securities may be issued include refunding outstanding
 obligations, obtaining funds for general operating expenses, and obtaining
 funds to lend to other public institutions and facilities. Municipal securi-
 ties in which a Fund may invest include private activity bonds, municipal
 leases, certificates of participation, pre-funded municipal securities and
 auction rate securities.
 
 INTEREST RATE SWAPS, MORTGAGE SWAPS, CREDIT SWAPS, CURRENCY SWAPS AND INTER-
 EST RATE CAPS, FLOORS AND COLLARS. Interest rate swaps involve the exchange
 by a Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest rate swaps in that
 they represent commitments to pay and receive interest. The notional princi-
 pal amount, however, is tied to a reference pool or pools of mortgages.
 Credit swaps involve the receipt of floating or fixed rate payments in
 exchange for assuming potential credit losses of an underlying security.
 Credit swaps give one party to a transaction the right to dispose of or
 acquire an asset (or group of assets), or the right to receive or make a
 payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest

 rate, to receive payment of interest on a notional principal amount from the
 party selling such interest rate cap. The purchase of an interest rate floor
 entitles the purchaser, to the extent that a specified index falls below a
 predetermined interest rate, to receive payments of interest on a notional
 principal amount from the party selling the interest rate floor. An interest
 rate collar is the combination of a cap and a floor that preserves a certain
 return within a predetermined range of interest rates.
 
 Certain Funds may enter into swap transactions for hedging purposes or to
 seek to increase total return. The use of interest rate, mortgage, credit
 and currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If the Investment Adviser is incorrect in its forecasts of market
 value, interest rates and currency exchange rates, the investment perfor-
 mance of a Fund would be less favorable than it would have been if these
 investment techniques were not used.
 
 LOAN PARTICIPATIONS. Certain Funds may invest in loan participations. A loan
 participation is an interest in a loan to a U.S. or foreign company or other
 borrower which is administered and sold by a financial intermediary. A Fund
 may only invest in loans to issuers in whose obligations it may otherwise
 invest. Loan participation interests may take the form of a direct or co-
 lending relationship with the corporate borrower, an assignment of an inter-
 est in the loan by a co-lender or another participant, or a participation in
 the seller's share of the loan. When a Fund acts as co-lender in connection
 with a participation interest or when it acquires certain participation
 interests, the Fund will have direct recourse against the borrower if the
 borrower fails to pay scheduled principal and interest. In cases where the
 Fund lacks direct recourse, it will look to the agent bank to enforce appro-
 priate credit remedies against the borrower. In these cases, the Fund may be
 subject to delays, expenses and risks that are greater than those that would
 have been involved if the Fund had purchased a direct obligation (such as
 commercial paper) of such borrower. Moreover, under the terms of the loan
 participation, the Fund may be regarded as a creditor of the agent bank
 (rather than of the underlying corporate borrower), so that the Fund may
 also be subject to the risk that the agent bank may become insolvent.
 
 INVERSE FLOATERS. Certain Funds may invest in inverse floating rate debt
 securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has not
 been in operation for less than five years). Certain information reflects
 financial results for a single Fund share. The total returns in the table
 represent the rate that an investor would have earned or lost on an invest-
 ment in a Fund (assuming reinvestment of all dividends and distributions).
 This information has been audited by Arthur Andersen LLP, whose report,
 along with a Fund's financial statements, is included in the Fund's annual
 report (available upon request).

 The following table sets forth the Investment Adviser's composite perfor-
 mance data relating to the historical performance of all discretionary pri-
 vate accounts managed by the Investment Adviser that have investment objec-
 tives, policies, and strategies substantially similar to the CORE Large Cap
 Value Fund. The information is provided to illustrate the past performance
 of the Investment Adviser in managing substantially similar accounts as mea-
 sured against the Russell 1000 Value Index and does not represent the per-
 formance of the CORE Large Cap Value Fund. Investors should not consider
 this performance data as a substitute for the performance of the CORE Large
 Cap Value Fund nor should investors consider this data as an indication of
 future performance of the CORE Large Cap Value Fund or of the Investment
 Adviser. The Russell 1000 Value Index is unmanaged and investors cannot
 invest directly in the Index.

 In accordance with the standards of the Association for Investment Manage-

 infor-
 
                                                                             119

 mation was calculated on a time-weighted and asset-weighted total return
 basis which includes realized and unrealized gains and losses plus income.
 The composite performance is net of applicable investment management fees,
 brokerage commissions, execution costs and custodial fees, without provision
 for federal and state taxes, if any. Total return performance of the CORE
 Large Cap Value Fund will be calculated in accordance with the regulations
 of the SEC. The SEC standardized average annual total return is neither
 time-weighted nor asset-weighted and is determined for specified periods by
 computing the annualized percentage change in the value of an initial amount
 that is invested in a share class of the Fund at the maximum public offering
 price. Investors should be aware that the differences in methodology between
 AIMR and SEC requirements could result in different performance data for
 identical time periods.
 
 All returns presented reflect the reinvestment of dividends and other earn-
 ings. The weighted-average expenses of the private accounts used in calcu-
 lating the Investment Adviser's net composite performance data were 0.59%
 annualized, which are lower than the estimated expenses of Service Shares of
 the CORE Large Cap Value Fund stated under "Fund Fees and Expenses" above.
 The performance of the private accounts would have been lower if they had
 been subject to the expenses of the CORE Large Cap Value Fund. In addition,
 the private accounts are not subject to the same diversification require-
 ments, specific tax restrictions and investment limitations imposed on the
 CORE Large Cap Value Fund by the Act and Subchapter M of the Code. Conse-
 quently, the performance results of the Investment Adviser's composite could
 have been adversely affected if the private accounts had been regulated as
 investment companies under the federal securities laws.

 Growth Fund. The information is provided to illustrate the past performance
 of the Investment Adviser in managing substantially similar accounts as mea-
 sured against the S&P 500 Index and does not represent the performance of
 the Strategic Growth Fund. Investors should not consider this performance
 data as a substitute for the performance of the Strategic Growth Fund nor
 should investors consider this data as an indication of future performance
 of the Strategic Growth Fund or of the Investment Adviser. The S&P 500 Index

 In accordance with the standards of the Association for Investment Manage-
 ment and Research ("AIMR"), the Investment Adviser's composite performance
 information was calculated on a time-weighted and asset-weighted total
 return basis which includes realized and unrealized gains and losses plus
 income. The
 composite performance is net of applicable investment management fees, bro-
 kerage commissions, execution costs and custodial fees, without provision
 for federal and state taxes, if any. Total return performance of the Strate-
 gic Growth Fund will be calculated in accordance with the regulations of the
 SEC. The SEC standardized average annual total return is neither time-
 weighted nor asset-weighted and is determined for specified periods by com-
 puting the annualized percentage change in the value of an initial amount
 that is invested in a share class of the Fund at the maximum public offering
 price. Investors should be aware that the differences in methodology between
 AIMR and SEC requirements could result in different performance data for
 identical time periods.
 
 All returns presented reflect the reinvestment of dividends and other earn-
 ings. The weighted-average expenses of the private accounts used in calcu-
 lating the Investment Adviser's net composite performance data were 0.76%
 annualized, which are lower than the estimated expenses of Service Shares of
 the Strategic Growth Fund stated under "Fund Fees and Expenses" above. The
 performance of the private accounts would have been lower if they had been
 subject to the expenses of the Strategic Growth Fund. In addition, the pri-
 vate accounts are not subject to the same diversification requirements, spe-
 cific tax restrictions and investment limitations imposed on the Strategic
 Growth Fund by the Act and Subchapter M of the Code. Consequently, the per-
 formance results of the Investment Adviser's composite could have been
 adversely affected if the private accounts had been regulated as investment
 companies under the federal securities laws.

General Investment Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the Balanced,
 Growth and Income, CORE Large Cap Value, CORE Large Cap Growth, CORE Small
 Cap Equity, Strategic Growth, Growth Opportunities, Mid Cap Value, Small Cap
 Value and Real Estate Securities Funds. Goldman Sachs Funds Management, L.P.
 serves as investment adviser to the CORE U.S. Equity and Capital Growth
 Funds. Goldman Sachs Asset Management and Goldman Sachs Funds Management,
 L.P. are each referred to in this Prospectus as the "Investment Adviser."
 
 VALUE STYLE FUNDS
 
 
 Goldman Sachs' Value Investment Philosophy:
 THE INVESTMENT ADVISER SEEKS COMPANIES THAT ARE DISCOUNTED DUE TO:
 .Company-specific problems that are over-discounted in the marketplace.
 .Cyclically out-of-favor status.
 .Unrecognized positive fundamentals.
 
 THE INVESTMENT ADVISER SEEKS TO IDENTIFY VALUE THROUGH:
 .Performing intensive, hands-on fundamental research.
 .Maintaining a long-term investment horizon.
 .A team approach to decision making.
 
 Value exists when a stock's price becomes inexpensive relative to the
 company's estimated earnings and/or dividend-paying ability over the long-
 term.
 
- --------------------------------------------------------------------------------
 
 GROWTH STYLE FUNDS
 
 
 Goldman Sachs' Growth Investment Philosophy:
 1. INVEST AS IF BUYING THE COMPANY/BUSINESS, NOT SIMPLY TRADING ITS STOCK:
 .Understand the business, management, products and competition.
 .Perform intensive, hands-on fundamental research.
 .Seek businesses with strategic competitive advantages.
 
                                                                               1
<PAGE>
 
 
 .Over the long-term, expect each company's stock price ultimately to track
  the growth of the business.
 
 2. BUY HIGH-QUALITY GROWTH BUSINESSES THAT POSSESS STRONG BUSINESS FRAN-
    CHISES, FAVORABLE LONG-TERM PROSPECTS AND EXCELLENT MANAGEMENT.
 
 3. PURCHASE SUPERIOR LONG-TERM GROWTH COMPANIES AT A FAVORABLE PRICE--SEEK
    TO PURCHASE AT A FAIR VALUATION, GIVING THE INVESTOR THE POTENTIAL TO
    FULLY CAPTURE RETURNS FROM ABOVE-AVERAGE GROWTH RATES.
 
 Growth companies have earnings expectations that exceed those of the stock
 market as a whole.
 
- --------------------------------------------------------------------------------
 
 QUANTITATIVE ("CORE") STYLE FUNDS
 
 
 Goldman Sachs' CORE Investment Philosophy:
 Goldman Sachs' quantitative style of funds--CORE--emphasizes the two build-
 ing blocks of active management: STOCK SELECTION and PORTFOLIO CONSTRUCTION.
 
 I. CORE Stock Selection
 The CORE Funds use the Goldman Sachs' proprietary multifactor model
 ("Multifactor Model"), a rigorous computerized rating system, to forecast
 the returns of securities held in each Fund's portfolio. The Multifactor
 Model incorporates common variables covering measures of:
 .VALUE (price-to-book, price-to-earnings, cash flow to enterprise value)
 .MOMENTUM (earnings momentum, price momentum, sustainable growth)
 .RISK (market risk, company-specific risk, earnings risk)
 .RESEARCH (fundamental research ratings of Goldman Sachs and other analysts)
 
 ALL OF THE ABOVE FACTORS ARE CAREFULLY EVALUATED WITHIN THE MULTIFACTOR
 MODEL SINCE EACH HAS DEMONSTRATED A SIGNIFICANT IMPACT ON THE PERFORMANCE OF
 THE SECURITIES AND MARKETS THEY WERE DESIGNED TO FORECAST. STOCK SELECTION
 IN THIS PROCESS COMBINES BOTH OUR QUANTITATIVE AND QUALITATIVE ANALYSIS.
 
 II. CORE Portfolio Construction
 A proprietary COMPUTER OPTIMIZER calculates every security combination (at
 every possible weighting) to construct the most efficient risk/return port-
 folio given each CORE Fund benchmark. In this process, the Investment
 Adviser manages risk by limiting deviations from the benchmark, running size
 and sector neutral portfolios.
 
 Goldman Sachs CORE Funds are fully invested, broadly diversified and offer
 consistent overall portfolio characteristics. They may serve as good founda-
 tions on which to build a portfolio.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 
 REAL ESTATE SECURITIES FUND
 
 
 Goldman Sachs' Real Estate Securities Investment Philosophy:
 When choosing the Fund's securities, the Investment Adviser:
 .Selects stocks based on quality of assets, experienced management and a
  sustainable competitive advantage.
 .Seeks to buy securities at a discount to the intrinsic value of the busi-
  ness (assets and management).
 .Seeks a team approach to decision making.
 
 Over time, REITs (which stand for Real Estate Investment Trusts) have
 offered investors important diversification and competitive total returns
 versus the broad equity market.

Fund Investment Objectives
and Strategies
 
 Goldman Sachs
 Balanced Fund
 
        FUND FACTS
- --------------------------------------------------------------------------------
 
        Objective:  Long-term growth of capital and current income
 
       Benchmarks:  S&P 500 Index and Lehman Brothers Aggregate Bond Index
 
 Investment Focus:  Large capitalization U.S. stocks and fixed-income securi-
                    ties
 
 Investment Style:  Asset Allocation, with growth and value (blend) equity
                    components
 
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks to provide long-term growth of capital and current income.
 The Fund seeks growth of capital primarily through investments in equity
 securities (stocks). The Fund seeks to provide current income through
 investment in fixed-income securities (bonds).
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Historically, stock and bond markets have often had different cycles, with
 one asset class rising when the other is falling. A balanced objective seeks
 to reduce the volatility associated with investing in a single market. There
 is no guarantee, however, that market cycles will move in opposition to one
 another or that a balanced investment program will successfully reduce vola-
 tility.
 
 Equity Securities. The Fund invests, under normal circumstances, between 45%
 and 65% of its total assets in equity securities. Although the Fund's equity
 investments consist primarily of publicly traded U.S. securities, the Fund
 may invest up to 10% of its total assets in the equity securities of foreign
 issuers, including issuers in countries with emerging markets or economies
 ("emerging countries") and equity securities quoted in foreign currencies. A
 portion of the Fund's portfo-

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
 lio of equity securities may be selected primarily to provide current income
 (including interests in REITs, convertible securities, preferred stocks,
 utility stocks, and interests in limited partnerships).
 
 Other. The Fund invests at least 25% of its total assets in fixed-income
 senior securities. The remainder of the Fund's assets are invested in other
 fixed-income securities and cash.
 
 The Fund's fixed-income securities primarily include:
 .Securities issued by the U.S. government, its agencies, instrumentalities
  or sponsored enterprises
 .Securities issued by corporations, banks and other issuers
 .Mortgage-backed and asset-backed securities
 
 The Fund may also invest up to 10% of its total assets in debt obligations
 (U.S. dollar and non-U.S.-dollar denominated) issued or guaranteed by one or
 more foreign governments or any of their political subdivisions, agencies or
 instrumentalities and foreign corporations or other entities. The issuers of
 these securities may be located in emerging countries.
 
 The percentage of the portfolio invested in equity and fixed-income securi-
 ties will vary from time to time as the Investment Adviser evaluates such
 securities' relative attractiveness based on market valuations, economic
 growth and inflation prospects. The allocation between equity and fixed-
 income securities is subject to the Fund's intention to pay regular quar-
 terly dividends. The amount of quarterly dividends can also be expected to
 fluctuate in accordance with factors such as prevailing interest rates and
 the percentage of the Fund's assets invested in fixed-income securities.
 
                                                                               5

 eign securities, including securities of issuers in emerging countries and

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term growth of capital and dividend income. The Fund
 seeks this objective through a broadly diversified portfolio of equity secu-
 rities of large- cap U.S. issuers that are selling at low to modest valua-
 tions relative to general market measures, such as earnings, book value and

 Equity Securities. The Fund invests, under normal circumstances, at least
 90% of its total assets in equity securities of U.S. issuers, including for-
 eign issuers that are traded in the United States.
 
 The Fund's investments are selected using both a variety of quantitative
 techniques and fundamental research in seeking to maximize the Fund's
 expected return, while maintaining risk, style, capitalization and industry
 characteristics similar to the Russell 1000 Value Index. The Fund seeks a
 portfolio comprised of companies with above average capitalizations and low
 to moderate valuations as measured by price/earnings ratios, book value and
 other fundamental accounting measures.
 
 Other. The Fund's investments in fixed-income securities are limited to
 securities that are considered cash equivalents.

 lio comprised of companies with small market capitalizations, strong
 expected earnings growth and momentum, and better valuation and risk charac-
 teristics than the Russell 2000 Index. If the issuer of a portfolio security

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all of its assets in equity securities and at least 65% of its total
 assets in equity securities of mid-cap companies with public stock market
 capitalizations (based upon shares available for trading on an unrestricted
 basis) within the range of the market capitalization of companies constitut-
 ing the Russell Midcap Index at the time of investment (currently between
 $400 million and $16 billion). If the capitalization of an issuer decreases
 below $400 million or increases above $16 billion after purchase, the Fund
 may, but is not required to, sell the securities. Dividend income, if any,
 is an incidental consideration. Although the Fund will invest primarily in
 publicly traded U.S. securities, it may invest up to 25% of its total assets
 in foreign securities, including securities of issuers in emerging countries
 and securities quoted in foreign currencies.
 
 Other. The Fund may also invest up to 35% of its total assets in fixed-
 income securities, such as corporate debt and bank obligations.

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term growth of capital.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, at least
 65% of its total assets in equity securities of companies with public stock
 market capitalizations of $1 billion or less at the time of investment.
 Under normal circumstances, the Fund's investment horizon for ownership of
 stocks will be two to three years. Dividend income, if any, is an incidental
 consideration. If the market capitalization of a company held by the Fund
 increases above $1 billion, the Fund may, consistent with its investment
 objective, continue to hold the security.
 
 The Fund invests in companies which the Investment Adviser believes are
 well- managed niche businesses that have the potential to achieve high or
 improving returns on capital and/or above average sustainable growth. The
 Fund may invest in securities of small market capitalization companies which
 may have experienced financial difficulties. Investments may also be made in
 companies that are in the early stages of their life and that the Investment
 Adviser believes have significant growth potential. The Investment Adviser
 believes that the companies in which the Fund may invest offer greater
 opportunity for growth of capital than larger, more mature, better known
 companies. Although the Fund will invest primarily in publicly traded U.S.
 securities, it may invest up to 25% of its total assets in foreign securi-
 ties, including securities of issuers in emerging countries and securities
 quoted in foreign currencies.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 companies with public stock market capitalizations in excess of $1 billion
 at the time of investment and in fixed-income securities, such as corporate
 debt and bank obligations.

         Objective:   Total return comprised of long-term growth of capital
                      and dividend income
 
         Benchmark:   Wilshire Real Estate Securities Index
 
  Investment Focus:   REITs and real estate industry companies
 
  Investment Style:   Growth at a discount
 
 
 INVESTMENT OBJECTIVE
 
 
 The Fund seeks total return comprised of long-term growth of capital and
 dividend income.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all and at least 80% of its total assets in a diversified portfolio
 of equity securities of issuers that are primarily engaged in or related to
 the real estate industry. The Fund expects that a substantial portion of its
 assets will be invested in REITs and real estate industry companies.
 
 A "real estate industry company" is a company that derives at least 50% of
 its gross revenues or net profits from the ownership, development, construc-
 tion, financing, management or sale of commercial, industrial or residential
 real estate or interests therein.
 
 The Fund's investment strategy is based on the premise that property market
 fundamentals are the primary determinant of growth, underlying the success
 of companies in the real estate industry. The Investment Adviser focuses on
 companies that can achieve sustainable growth in cash flow and dividend pay-
 ing capability. The Investment Adviser attempts to purchase securities so
 that its underlying portfolio will be diversified geographically and by
 property type. Although the Fund will invest primarily in publicly traded
 U.S. securities, it may invest up to 15% of its total assets in foreign
 securities, including securities of issuers in emerging countries and secu-
 rities quoted in foreign currencies.
 
 Investing in REITs involves certain unique risks in addition to those risks
 associated with investing in the real estate industry in general. Equity
 REITs may be affected by changes in the value of the underlying property
 owned by the REITs.

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
 
 Mortgage REITs may be affected by the quality of any credit extended. REITs
 are dependent upon management skill, may not be diversified, and are subject
 to heavy cash flow dependency, default by borrowers and self-liquidation.
 REITs are also subject to the possibilities of failing to qualify for tax
 free pass-through of income and failing to maintain their exemptions from
 investment company registration. REITs whose underlying properties are con-
 centrated in a particular industry or geographic region are also subject to
 risks affecting such industries and regions.
 
 REITs (especially mortgage REITs) are also subject to interest rate risks.
 When interest rates decline, the value of a REIT's investment in fixed rate
 obligations can be expected to rise. Conversely, when interest rates rise,
 the value of a REIT's investment in fixed rate obligations can be expected
 to decline. In contrast, as interest rates on adjustable rate mortgage loans
 are reset periodically, yields on a REIT's investment in such loans will
 gradually align themselves to reflect changes in market interest rates,
 causing the value of such investments to fluctuate less dramatically in
 response to interest rate fluctuations than would investments in fixed rate
 obligations.
 
 The REIT investments of the Real Estate Securities Fund often do not provide
 complete tax information to the Fund until after the calendar year-end. Con-
 sequently, because of the delay, it may be necessary for the Fund to request
 permission to extend the deadline for issuance of Forms 1099-DIV beyond Jan-
 uary 31.
 
 Other. The Fund may invest up to 20% of its total assets in fixed-income
 securities, such as corporate debt and bank obligations, that offer the
 potential to further the Fund's investment objective.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

All Funds:
 
 .CREDIT/DEFAULT RISK--The risk that an issuer of fixed-income securities held
 by a Fund (which may have low credit ratings) may default on its obligation to
 pay interest and repay principal.
 .FOREIGN RISKS--The risk that when a Fund invests in foreign securities, it
 will be subject to risk of loss not typically associated with domestic
 issuers. Loss may result because of less foreign government regulation, less
 public information and less economic, political and social stability. Loss may
 also result from the imposition of exchange controls, confiscations and other
 government restrictions. A Fund will also be subject to the risk of negative
 foreign currency rate fluctuations. Foreign risks will normally be greatest
 when a Fund invests in issuers located in emerging countries.
 .EMERGING COUNTRIES RISK--The securities markets of Asian, Latin American,
 Eastern European, African and other emerging countries are less liquid, are
 especially subject to greater price volatility, have smaller market capital-
 izations, have less government regulation and are not subject to as extensive
 and frequent accounting, financial and other reporting requirements as the
 securities markets of more developed countries. Further, investment in equity
 securities of issuers located in Russia and certain other emerging countries
 involves risk of loss resulting from problems in share registration and cus-
 tody and substantial economic and political disruptions. These risks are not
 normally associated with investment in more developed countries.
 .STOCK RISK--The risk that stock prices have historically risen and fallen in
 periodic cycles. As of the date of this Prospectus, U.S. stock markets and
 certain foreign stock markets were trading at or close to record high levels.
 There is no guarantee that such levels will continue.
 .DERIVATIVES RISK--The risk that loss may result from a Fund's investments in
 options, futures, swaps, structured securities and other derivative instru-
 ments. These instruments may be leveraged so that small changes may produce
 disproportionate losses to a Fund.
 .INTEREST RATE RISK--The risk that when interest rates increase, securities
 held by a Fund will decline in value. Long-term fixed-income securities will
 normally have more price volatility because of this risk than short-term secu-
 rities.
 .MANAGEMENT RISK--The risk that a strategy used by the Investment Adviser may
 fail to produce the intended results.
 .MARKET RISK--The risk that the value of the securities in which a Fund invests
 may go up or down in response to the prospects of individual companies and/or
 general economic conditions. Price changes may be temporary or last for
 extended periods.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 .LIQUIDITY RISK--The risk that a Fund will not be able to pay redemption pro-
 ceeds within the time period stated in this Prospectus because of unusual mar-
 ket conditions, an unusually high volume of redemption requests, or other rea-
 sons. Funds that invest in non-investment grade fixed-income securities, small
 capitalization stocks, REITs and emerging country issuers will be especially
 subject to the risk that during certain periods the liquidity of particular
 issuers or industries, or all securities within these investment categories,
 will shrink or disappear suddenly and without warning as a result of adverse
 economic, market or political events, or adverse investor perceptions whether
 or not accurate.
 .OTHER RISKS--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Specific Funds:
 
 .SMALL CAP STOCK AND REIT RISK--The securities of small capitalization stocks
 and REITs involve greater risks than those associated with larger, more estab-
 lished companies and may be subject to more abrupt or erratic price movements.
 Securities of such issuers may lack sufficient market liquidity to enable a
 Fund to effect sales at an advantageous time or without a substantial drop in
 price.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Insti-
 tutional Shares from year to year; and (b) how the average annual returns of
 a Fund's Institutional Shares compare to those of broad-based securities
 market indices. The bar chart and table assume reinvestment of dividends and
 distributions. A Fund's past performance is not necessarily an indication of
 how the Fund will perform in the future. Performance reflects expense limi-
 tations in effect. If expense limitations were not in place, a Fund's per-
 formance would have been reduced. The CORE Large Cap Value and Real Estate
 Securities Funds did not commence operations until December 31, 1998 and
 July 27, 1998. The Strategic Growth and Growth Opportunities Funds had not
 commenced operations as of the date of this Prospectus. Since these Funds
 have less than one calendar year's performance, no performance information
 is provided in this section.

 GSAM is a separate operating division of Goldman Sachs, which registered as
 an investment adviser in 1981. GSFM, a registered investment adviser since
 1990, is a Delaware limited partnership which is an affiliate of Goldman
 Sachs. The Goldman Sachs Group, L.P., which controls the Investment Advis-
 ers, announced that it will pursue an initial public offering of the firm in
 the late spring or early summer of 1999. Simultaneously with the offering,
 the Goldman Sachs Group, L.P. will merge into The Goldman Sachs Group, Inc.
 As of February 28, 1999, GSAM and GSFM, together with their affiliates,
 acted as investment adviser or distributor for assets in excess of $199 bil-
 lion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser makes the investment decisions
 for the Funds and places purchase and sale orders for the Funds' portfolio
 transactions in U.S. and foreign markets. As permitted by applicable law,
 these orders may be directed to any brokers, including Goldman Sachs and its
 affiliates. While the Investment Adviser is ultimately responsible for the
 management of the Funds, it is able to draw upon the research and expertise
 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that a Fund
 could sustain losses during periods in which Goldman Sachs and its affili-
 ates and other accounts achieve significant profits on their trading for
 proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly
 
                                                                              47

 known as the "Year 2000 Problem"). To the extent these systems conduct for-
 ward-looking calculations, these computer problems may occur prior to
 January 1, 2000. Like other investment companies and financial and business
 organizations, the Funds could be adversely affected in their ability to
 process securities trades, price securities, provide shareholder account
 services and otherwise conduct normal business operations if the Investment
 Adviser or other Fund service providers do not adequately address this prob-
 lem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.

Dividends
 
Each Fund pays dividends from its net investment income and distributions from
net realized capital gains. You may choose to have dividends and distributions
paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund. Spe-
 cial restrictions may apply for certain ILA Portfolios. See the Additional
 Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from net capital gains
are declared and paid as follows:

From time to time a portion of a Fund's dividends may constitute a return of
capital.
 
At the time of an investor's purchase of shares of a Fund, a portion of the NAV
per share may be represented by undistributed income or realized or unrealized
appreciation of the Fund's portfolio securities. Therefore, subsequent distri-
butions on such shares from such income or realized appreciation may be taxable
to the investor even if the NAV of the shares is, as a result of the distribu-
tions, reduced below the cost of such shares and the distributions (or portions
thereof) represent a return of a portion of the purchase price.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Institutional
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Institutional Shares Of The Funds?
 You may purchase Institutional Shares on any business day at their net asset
 value ("NAV") next determined after receipt of an order. No sales load is
 charged. You should place an order with Goldman Sachs at 1-800-621-2550 and
 either:
 .Wire federal funds to The Northern Trust Company ("Northern"), as
  subcustodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian) on the next business day; OR
 .Initiate an Automated Clearing House Network ("ACH") transfer to Northern;
  OR
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 In order to make an initial investment in a Fund, you must furnish to the
 Fund or Goldman Sachs the Account Application attached to this Prospectus.
 Purchases of Institutional Shares must be settled within three business days
 of receipt of a complete purchase order.
 
 How Do I Purchase Shares Through A Financial Institution?
 Certain institutions (including banks, trust companies, brokers and invest-
 ment advisers) that provide recordkeeping, reporting and processing services
 to their customers may be authorized to accept, on behalf of Goldman Sachs
 Trust (the "Trust"), purchase, redemption and exchange orders placed by or
 on behalf of their customers, and may designate other intermediaries to
 accept such orders, if approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized institution or intermediary on a busi-
  ness day, and the order will be priced at the Fund's NAV next determined
  after such acceptance.
 .Authorized institutions and intermediaries will be responsible for trans-
  mitting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 You should contact your institution or intermediary to learn whether it is
 authorized to accept orders for the Trust.
 
                                                                              51
<PAGE>
 
 
 These institutions may receive payments from the Funds or Goldman Sachs for
 the services provided by them with respect to the Funds' Institutional
 Shares. These payments may be in addition to other payments borne by the
 Funds.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to certain institutions and other persons in
 connection with the sale, distribution and/or servicing of shares of the
 Funds and other Goldman Sachs Funds. Subject to applicable NASD regulations,
 the Investment Adviser, Distributor and/or their affiliates may also con-
 tribute to various cash and non-cash incentive arrangements to promote the
 sale of shares. This additional compensation can vary among such institu-
 tions depending upon such factors as the amounts their customers have
 invested (or may invest) in particular Goldman Sachs Funds, the particular
 program involved, or the amount of reimbursable expenses. Additional compen-
 sation based on sales may, but is currently not expected to, exceed 0.50%
 (annualized) of the amount invested.
 
 In addition to Institutional Shares, each Fund also offers other classes of
 shares to investors. These other share classes are subject to different fees
 and expenses (which affect performance), have different minimum investment
 requirements and are entitled to different services than Institutional
 Shares. Information regarding these other share classes may be obtained from
 your sales representative or from Goldman Sachs by calling the number on the
 back cover of this Prospectus.

 The minimum investment requirement may be waived for current and former
 officers, partners, directors or employees of Goldman Sachs or any of its
 affiliates or for other investors at the discretion of the Trust's officers.
 No minimum amount is required for subsequent investments.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment amounts.
 .Reject or restrict any purchase or exchange orders by a particular pur-
  chaser (or group of related purchasers). This may occur, for example, when
  a pattern of frequent purchases, sales or exchanges of Institutional Shares
  of a Fund is evident, or if purchases, sales or exchanges are, or a subse-
  quent abrupt redemption might be, of a size that would disrupt the manage-
  ment of a Fund.
 
                                                                              53
<PAGE>
 
 
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Institutional
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _____________________________________________________
                 Number of Outstanding Shares of the Class
 
 
 The Funds' investments are valued based on market quotations or, if accurate
 quotations are not readily available, the fair value of the Fund's invest-
 ments may be determined in good faith under procedures established by the
 Trustees.
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will not be priced on any day
  the New York Stock Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form.
 
 NOTE: THE TIME AT WHICH TRANSACTIONS AND SHARES ARE PRICED AND THE TIME BY
 WHICH ORDERS MUST BE RECEIVED MAY BE CHANGED IN CASE OF AN EMERGENCY OR IF
 REGULAR TRADING ON THE NEW YORK STOCK EXCHANGE IS STOPPED AT A TIME OTHER
 THAN 4:00 P.M. NEW YORK TIME.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 In addition, the impact of events that occur after the publication of market
 quotations used by a Fund to price its securities but before the close of
 regular trading on the New York Stock Exchange will normally not be
 reflected in a Fund's next determined NAV unless the Trust, in its discre-
 tion, makes an adjustment in light of the nature and materiality of the
 event, its effect on Fund operations and other relevant factors.

 HOW TO SELL SHARES
 
 
 How Can I Sell Institutional Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. GENERALLY, EACH FUND WILL REDEEM ITS INSTITU-
 TIONAL SHARES UPON REQUEST ON ANY BUSINESS DAY AT THEIR NAV NEXT DETERMINED
 AFTER RECEIPT OF SUCH REQUEST IN PROPER FORM. You may request that redemp-
 tion proceeds be sent to you by check or by wire (if the wire instructions
 are on record). Redemptions may be requested in writing or by telephone.

</TABLE>
 Certain institutions and intermediaries are authorized to accept redemption
 requests on behalf of the Funds as described under "How Do I Purchase Shares
 Through A Financial Institution?"
 
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
 
                                                                              55
<PAGE>
 
 
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 NOTE: IT MAY BE DIFFICULT TO MAKE TELEPHONE REDEMPTIONS IN TIMES OF DRASTIC
 ECONOMIC OR MARKET CONDITIONS.
 
 How Are Redemption Proceeds Paid?
 BY WIRE: You may arrange for your redemption proceeds to be wired as federal
 funds to the bank account designated in your Account Application. The fol-
 lowing general policies govern wiring redemption proceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If you are selling shares you recently paid for by
  check, the Fund will pay you when your check has cleared, which may take up
  to 15 days. If the Federal Reserve Bank is closed on the day that the
  redemption proceeds would ordinarily be wired, wiring the redemption pro-
  ceeds may be delayed one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  account application to the Transfer Agent.
 .Neither the Trust, Goldman Sachs nor any other institution assume any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
 
 BY CHECK: You may elect in writing to receive your redemption proceeds by
 check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of a properly executed redemp-
 tion request. If you are selling shares you recently paid for by check, the
 Fund will pay you when your check has cleared, which may take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Institutions (including banks, trust companies, brokers and investment
  advisers) are responsible for the timely transmittal of redemption requests
  by their customers to the Transfer Agent. In order to facilitate the timely
  transmittal of redemption requests, these institutions may set times by
  which they must receive

  redemption requests. These institutions may also require additional docu-
  mentation from you.
 
 The Trust reserves the right to:
 .Redeem your shares if your account balance falls below $50 as a result of
  earlier redemptions. The Funds will not redeem your shares on this basis if
  the value of your account falls below the minimum account balance solely as
  a result of market conditions. The Fund will give you 60 days' prior writ-
  ten notice to allow you to purchase sufficient additional shares of the
  Fund in order to avoid such redemption.
 .Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange Institutional Shares of a Fund at NAV for Institutional
 Shares of any other Goldman Sachs Fund. The exchange privilege may be mate-
 rially modified or withdrawn at any time upon 60 days' written notice to
 you.

</TABLE>
 
 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 
                                                                              57
<PAGE>
 
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types of Reports Will I Be Sent Regarding Investments In Institutional
 Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-621-2550. You will also be provided with a
 printed confirmation for each transaction in your account and a monthly
 account statement. The Funds do not generally provide sub-accounting servic-
 es.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Fund distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Fund's net investment income, certain net realized
 foreign exchange gains and net short-term capital gains. They are taxable as
 long-term capital gains to the extent they are attributable to the Fund's
 excess of net long-term capital gains over net short-term capital losses.
 The tax status of any distribution is the same regardless of how long you
 have been in the Fund and whether you reinvest in additional shares or take
 the distribution as cash. Certain distributions paid by a Fund in January of
 a given year may be taxable to shareholders as if received the prior Decem-
 ber 31. The tax status and amounts of the distributions for each calendar
 year will be detailed in your annual tax statement from the Fund.
 
 A Fund's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Fund receives from U.S. domestic
 corporations may be eligible, in the hands of the corporate shareholders,
 for the corporate dividends-received deduction, subject to certain holding
 period requirements and debt financing limitations.
 
 Each Fund may be subject to foreign withholding or other foreign taxes on
 income or gain from certain foreign securities. In general, the Funds may
 deduct these taxes in computing their taxable income.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In its efforts to adhere to these requirements, the
 Funds may have to limit their investment activity in some types of instru-
 ments.
 
                                                                              59
<PAGE>
 
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements for the periods that you hold shares.) Any loss rec-
 ognized on shares held for six months or less will be treated as a long-term
 capital loss to the extent of any capital gain dividends that were received
 with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from a Fund or on the value of the shares
 held by you. More tax information is provided in the Additional Statement.
 You should also consult your own tax adviser for information regarding all
 tax consequences applicable to your investments in the Funds.

Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 
 A. General Portfolio Risks
 
 The Funds will be subject to the risks associated with equity securities.
 "Equity securities" include common stocks, preferred stocks, interests in
 real estate investment trusts, convertible debt obligations, convertible
 preferred stocks, equity interests in trusts, partnerships, joint ventures,
 limited liability companies and similar enterprises, warrants and stock pur-
 chase rights. In general, stock values fluctuate in response to the activi-
 ties of individual companies and in response to general market and economic
 conditions. Accordingly, the value of the stocks that a Fund holds may
 decline over short or extended periods. The stock markets tend to be cycli-
 cal, with periods when stock prices generally rise and periods when prices
 generally decline. The volatility of equity securities means that the value
 of your investment in the Funds may increase or decrease. As of the date of
 this Prospectus, certain stock markets were trading at or close to record
 high levels and there can be no guarantee that such levels will continue.
 
 To the extent that a Fund invests in fixed-income securities, that Fund will
 also be subject to the risks associated with its fixed-income securities.
 These risks include interest rate risk, credit risk and call/extension risk.
 In general, interest rate risk involves the risk that when interest rates
 decline, the market value of fixed-income securities tends to increase. Con-
 versely, when interest rates increase, the market value of fixed-income
 securities tends to decline. Credit risk involves the risk that an issuer
 could default on its obligations, and a Fund will not recover its invest-
 ment. Call risk and extension risk are normally present in mortgage-backed
 securities and asset-backed securities. For example, homeowners have the
 option to prepay their mortgages. Therefore, the duration of a security
 backed by home mortgages can either shorten (call risk) or lengthen (exten-
 sion risk). In general, if interest rates on new mortgage loans fall suffi-
 ciently below the interest rates on existing outstanding mortgage loans, the
 rate of prepayment would be expected to increase. Conversely, if mortgage
 loan interest rates rise above the interest rates on existing outstanding
 mortgage loans, the rate of prepayment would be expected to decrease. In
 either case, a change in the prepayment rate can result in losses to invest-
 ors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by
 
                                                                              61
<PAGE>
 
 
 dividing the lesser of the dollar amount of sales or purchases of portfolio
 securities by the average monthly value of a Fund's portfolio securities,
 excluding securities having a maturity at the date of purchase of one year
 or less. See "Financial Highlights" in Appendix B for a statement of the
 Funds' historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all investment objectives and policies not specifically designated as
 fundamental are non-fundamental and may be changed without shareholder
 approval. If there is a change in a Fund's investment objective, you should
 consider whether that Fund remains an appropriate investment in light of
 your then current financial position and needs.
 
 B. Other Portfolio Risks
 
 
 RISKS OF INVESTING IN SMALL CAPITALIZATION COMPANIES AND REITS. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such securities. Small capitalization companies
 and REITs may be thinly traded and may have to be sold at a discount from
 current market prices or in small lots over an extended period of time. In
 addition, these securities are subject to the risk that during certain peri-
 ods the liquidity of particular issuers or industries, or all securities in
 these investment categories, will shrink or disappear suddenly and without
 warning as a result of adverse economic or market conditions, or adverse
 investor perceptions whether or not accurate. Because of the lack of suffi-
 cient market liquidity, a Fund may incur losses because it will be required
 to effect sales at a disadvantageous time and only then at a substantial
 drop in price. Small capitalization companies and REITs include "unseasoned"
 issuers that do not have an established financial history; often have lim-
 ited product lines, markets or financial resources; may depend on or use a
 few key personnel for management; and may be susceptible to losses and risks
 of bankruptcy. Transaction costs for these investments are often higher than
 those of larger capitalization companies. Investments in small capitaliza-
 tion companies and REITs may be more difficult to price precisely than other
 types of securities because of their characteristics and lower trading vol-
 umes.

 RISKS OF FOREIGN INVESTMENTS. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts after January 1, 1999 that refer to existing currencies
 rather than the euro; the establishment and maintenance of exchange rates
 for currencies being converted into the euro; the fluctuation of the euro
 relative to non-euro currencies during the transition period from January 1,
 1999 to December 31, 2001 and beyond; whether the interest rate, tax and
 labor regimes of European countries participating in the euro will converge
 over time; and whether the conversion of the currencies of other countries
 that now are or may in the future become members of the European Union
 ("EU"), may have an impact on the euro. These or other factors, including
 political and economic risks, could cause market disruptions, and could
 adversely affect the value of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Efforts in foreign countries to remediate potential Year
 
                                                                              63

 2000 problems are not as extensive as those in the United States. As a
 result, the operations of foreign markets, foreign issuers and foreign gov-
 ernments may be disrupted by the Year 2000 Problem, and the investment port-
 folio of a Fund may be adversely affected. Furthermore, with respect to cer-
 tain foreign countries, there is a possibility of nationalization,
 expropriation or confiscatory taxation, imposition of withholding or other
 taxes on dividend or interest payments (or, in some cases, capital gains),
 limitations on the removal of funds or other assets of the Funds, and polit-
 ical or social instability or diplomatic developments which could affect
 investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such debt, and a Fund may have limited recourse to compel
 payment in the event of a default. Periods of economic uncertainty may
 result in the volatility of market prices of sovereign debt, and in turn a
 Fund's NAV, to a greater extent than the volatility inherent in debt obliga-
 tions of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Funds may also invest in European Depository
 Receipts ("EDRs") or other similar instruments representing securities of
 foreign issuers. ADRs represent the right to receive securities of foreign
 issuers deposited in a domestic bank or a correspondent bank. Prices of ADRs
 are quoted in U.S. dollars, and ADRs are traded in the United States. EDRs
 and GDRs are receipts evidencing an arrangement with a non-U.S. bank. EDRs
 and GDRs are not necessarily quoted in the same currency as the underlying
 security.
 
 RISKS OF EMERGING COUNTRIES. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are gener-

                                                                      APPENDIX A
 
 ally located in the Asia-Pacific region, Eastern Europe, Latin and South
 America and Africa. A Fund's purchase and sale of portfolio securities in
 certain emerging countries may be constrained by limitations as to daily
 changes in the prices of listed securities, periodic trading or settlement
 volume and/or limitations on aggregate holdings of foreign investors. Such
 limitations may be computed based on the aggregate trading volume by or
 holdings of a Fund, the Investment Adviser, its affiliates and their respec-
 tive clients and other service providers. A Fund may not be able to sell
 securities in circumstances where price, trading or settlement volume limi-
 tations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, it is anticipated that
 a Fund may invest in such countries through other investment funds in such
 countries.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and
 
                                                                              65
<PAGE>
 
 
 ethnic, religious and racial disaffection, among other factors, have also
 led to social unrest, violence and/or labor unrest in some emerging coun-
 tries. Unanticipated political or social developments may result in sudden
 and significant investment losses. Investing in emerging countries involves
 greater risk of loss due to expropriation, nationalization, confiscation of
 assets and property or the imposition of restrictions on foreign investments
 and on repatriation of capital invested.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Fund in emerging countries may not be as sound as the
 creditworthiness of firms used in more developed countries. As a result, the
 Fund may be subject to a greater risk of loss if a securities firm defaults
 in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than investments in countries with more developed securities mar-
 kets (such as the United States, Japan and most Western European countries).
 A Fund's investments in emerging countries are subject to the risk that the
 liquidity of a particular investment, or investments generally, in such
 countries will shrink or disappear suddenly and without warning as a result
 of adverse economic, market or political conditions or adverse investor per-
 ceptions, whether or not accurate. Because of the lack of sufficient market
 liquidity, a Fund may incur losses because it will be required to effect
 sales at a disadvantageous time and only then at a substantial drop in
 price. Investments in emerging countries may be more difficult to price pre-
 cisely because of the characteristics discussed above and lower trading vol-
 umes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.

 RISKS OF DERIVATIVE INVESTMENTS. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities and currency transactions involve additional risk of
 loss. Loss can result from a lack of correlation between changes in the
 value of derivative instruments and the portfolio assets (if any) being
 hedged, the potential illiquidity of the markets for derivative instruments,
 or the risks arising from margin requirements and related leverage factors
 associated with such transactions. The use of these management techniques
 also involves the risk of loss if the Investment Adviser is incorrect in its
 expectation of fluctuations in securities prices, interest rates or currency
 prices. Each Fund may also invest in derivative investments for non-hedging
 purposes (that is, to seek to increase total return). Investing for non-
 hedging purposes is considered a speculative practice and presents even
 greater risk of loss.
 
 RISKS OF ILLIQUID SECURITIES. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of
  more than seven days
 .Certain over-the-counter options
 .Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that such
  restricted security is eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 CREDIT RISKS. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Further informa-
 tion is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse
 
                                                                              67
<PAGE>
 
 
 economic conditions or changing circumstances may weaken their issuers'
 capacity to pay interest and repay principal. A security will be deemed to
 have met a rating requirement if it receives the minimum required rating
 from at least one such rating organization even though it has been rated
 below the minimum rating by one or more other rating organizations, or if
 unrated by such rating organizations, determined by the Investment Adviser
 to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 TEMPORARY INVESTMENT RISKS. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 .U.S. government securities
 .Commercial paper rated at least A-2 by Standard & Poor's or P-2 by Moody's
 .Certificates of deposit
 .Bankers' acceptances
 .Repurchase agreements
 .Non-convertible preferred stocks and non-convertible corporate bonds with a
  remaining maturity of less than one year
 
 When a Fund's assets are invested in such instruments, the Fund may not be
 achieving its investment objective.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 CONVERTIBLE SECURITIES. Each Fund may invest in convertible securities. Con-
 vertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which a Fund invests are subject to the same
 rating criteria as its other investments in
 
68
<PAGE>
 
                                                                      APPENDIX A
 
 fixed-income securities. Convertible securities have both equity and fixed-
 income risk characteristics. Like all fixed-income securities, the value of
 convertible securities is susceptible to the risk of market losses attribut-
 able to changes in interest rates. Generally, the market value of convert-
 ible securities tends to decline as interest rates increase and, conversely,
 to increase as interest rates decline. However, when the market price of the
 common stock underlying a convertible security exceeds the conversion price
 of the convertible security, the convertible security tends to reflect the
 market price of the underlying common stock. As the market price of the
 underlying common stock declines, the convertible security, like a fixed-
 income security, tends to trade increasingly on a yield basis, and thus may
 not decline in price to the same extent as the underlying common stock.
 
 FOREIGN CURRENCY TRANSACTIONS. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, certain Funds may also
 enter into such transactions to seek to increase total return, which is con-
 sidered a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in connection with investments in foreign securities when, in the
 judgment of the Investment Adviser, it would be beneficial to convert such
 currency into U.S. dollars at a later date (e.g., the Investment Adviser may
 anticipate the foreign currency to appreciate against the U.S. dollar).
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are
 
                                                                              69
<PAGE>
 
 
 not guaranteed by an exchange or clearinghouse, a default on a contract
 would deprive a Fund of unrealized profits, transaction costs or the bene-
 fits of a currency hedge or could force the Fund to cover its purchase or
 sale commitments, if any, at the current market price.
 
 STRUCTURED SECURITIES. Each Fund may invest in structured securities. Struc-
 tured securities are securities whose value is determined by reference to
 changes in the value of specific currencies, interest rates, commodities,
 indices or other financial indicators (the "Reference") or the relative
 change in two or more References. The interest rate or the principal amount
 payable upon maturity or redemption may be increased or decreased depending
 upon changes in the applicable Reference. Structured securities may be posi-
 tively or negatively indexed, so that appreciation of the Reference may pro-
 duce an increase or decrease in the interest rate or value of the security
 at maturity. In addition, changes in the interest rates or the value of the
 security at maturity may be a multiple of changes in the value of the Refer-
 ence. Consequently, structured securities may present a greater degree of
 market risk than other types of fixed-income securities and may be more vol-
 atile, less liquid and more difficult to price accurately than less complex
 securities.
 
 REITS. Each Fund may invest in REITS. REITS are pooled investment vehicles
 that invest primarily in either real estate or real estate related loans.
 The value of a REIT is affected by changes in the value of the properties
 owned by the REIT or securing mortgage loans held by the REIT. REITs are
 dependent upon the ability of the REITs' managers, and are subject to heavy
 cash flow dependency, default by borrowers and the qualification of the
 REITs under applicable regulatory requirements for favorable income tax
 treatment. REITs are also subject to risks generally associated with invest-
 ments in real estate including possible declines in the value of real
 estate, general and local economic conditions, environmental problems and
 changes in interest rates. To the extent that assets underlying a REIT are
 concentrated geographically, by property type or in certain other respects,
 these risks may be heightened. A Fund will indirectly bear its proportionate
 share of any expenses, including management fees, paid by a REIT in which it
 invests.
 
 OPTIONS ON SECURITIES, SECURITIES INDICES AND FOREIGN CURRENCIES. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which they may invest or on any securities index comprised of
 securities in which they may invest. A Fund

<PAGE>
 
                                                                      APPENDIX A
 
 may also, to the extent that it invests in foreign securities, purchase and
 sell (write) put and call options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater illiquidity and credit risks.
 
 FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 government securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their term structures, sector selec-
 tion and durations in accordance with their investment objectives and poli-
 cies. Each Fund may also enter into closing purchase and sale transactions
 with respect to such contracts and options. A Fund will engage in futures
 and related options transactions for bona fide hedging purposes as defined
 in regulations of the Commodity Futures Trading Commission or to seek to
 increase total return to the extent permitted by such regulations. A Fund
 may not purchase or sell futures contracts or purchase or sell related
 options to seek to increase total return, except for closing purchase or
 sale transactions, if immediately thereafter the sum of the amount of ini-
 tial margin deposits and premiums paid on the Fund's outstanding positions
 in futures and related options entered
 
                                                                              71
<PAGE>
 
 
 into for the purpose of seeking to increase total return would exceed 5% of
 the market value of the Fund's net assets.
 
 Futures contracts and related options present the following risks:
 .While a Fund may benefit from the use of futures and options on futures,
  unanticipated changes in interest rates, securities prices or currency
  exchange rates may result in poorer overall performance than if the Fund
  had not entered into any futures contracts or options transactions.
 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and a Fund may be exposed to additional risk
  of loss.
 .The loss incurred by a Fund in entering into futures contracts and in writ-
  ing call options on futures is potentially unlimited and may exceed the
  amount of the premium received.
 .Futures markets are highly volatile and the use of futures may increase the
  volatility of a Fund's NAV.
 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to a Fund.
 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.
 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 EQUITY SWAPS. Each Fund may invest in equity swaps. Equity swaps allow the
 parties to a swap agreement to exchange the dividend income or other compo-
 nents of return on an equity investment (for example, a group of equity
 securities or an index) for a component of return on another non-equity or
 equity investment.
 
 An equity swap may be used by a Fund to invest in a market without owning or
 taking physical custody of securities in circumstances in which direct
 investment may be restricted for legal reasons or is otherwise impractical.
 Equity swaps are derivatives and their value can be very volatile. To the
 extent that the Investment Adviser does not accurately analyze and predict
 the potential relative fluctuation of the components swapped with another
 party, a Fund may suffer a loss. The value of some components of an equity
 swap (such as the dividends on a common stock) may also be sensitive to
 changes in interest rates. Furthermore, a Fund may suffer a loss if the
 counterparty defaults.
 
 WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS. Each Fund may purchase when-
 issued securities and make contracts to purchase or sell securities for a
 fixed price at a future date beyond customary settlement time. When-issued
 securities are securities that have been authorized, but not yet issued.
 When-issued securities are purchased in order to secure what is considered
 to be an advantageous price
 
72
<PAGE>
 
                                                                      APPENDIX A
 
 and yield to the Fund at the time of entering into the transaction. A for-
 ward commitment involves the entering into a contract to purchase or sell
 securities for a fixed price at a future date beyond the customary settle-
 ment period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 REPURCHASE AGREEMENTS. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with primary dealers in U.S. government securities and member banks of the
 Federal Reserve System which furnish collateral at least equal in value or
 market price to the amount of their repurchase obligation.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's costs associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Certain
 Funds, together with other registered investment companies having advisory
 agreements with the Investment Adviser or any of its affiliates, may trans-
 fer uninvested cash balances into a single joint account, the daily aggre-
 gate balance of which will be invested in one or more repurchase agreements.
 
 LENDING OF PORTFOLIO SECURITIES. Each Fund may engage in securities lending.
 Securities lending involves the lending of securities owned by a Fund to
 financial institutions such as certain broker-dealers. The borrowers are
 required to secure their loan continuously with cash, cash equivalents, U.S.
 government securities or letters of credit in an amount at least equal to
 the market value of the securities loaned. Cash collateral may be invested
 in cash equivalents. If the Investment Adviser determines to make securities
 loans, the value of the securities loaned may not exceed 33 1/3% of the
 value of the total assets of a Fund (including the loan collateral).
 
                                                                              73
<PAGE>
 
 
 
 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 SHORT SALES AGAINST-THE-BOX. Certain Funds may make short sales against-the-
 box. A short sale against-the-box means that at all times when a short posi-
 tion is open the Fund will own an equal amount of securities sold short, or
 securities convertible into or exchangeable for, without payment of any fur-
 ther consideration, an equal amount of the securities of the same issuer as
 the securities sold short.
 
 PREFERRED STOCK, WARRANTS AND RIGHTS. Each Fund may invest in preferred
 stock, warrants and rights. Preferred stocks are securities that represent
 an ownership interest providing the holder with claims on the issuer's earn-
 ings and assets before common stock owners but after bond owners. Unlike
 debt securities, the obligations of an issuer of preferred stock, including
 dividend and other payment obligations, may not typically be accelerated by
 the holders of such preferred stock on the occurrence of an event of default
 or other non-compliance by the issuer of the preferred stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.
 
 OTHER INVESTMENT COMPANIES. Each Fund may invest in securities of other
 investment companies (including SPDRs and WEBs, as defined below) subject to
 statutory limitations prescribed by the Investment Company Act. These limi-
 tations include a prohibition on any Fund acquiring more than 3% of the vot-
 ing shares of any other investment company, and a prohibition on investing
 more than 5% of a Fund's total assets in securities of any one investment
 company or more than 10% of its total assets in securities of all investment
 companies. A Fund will indirectly bear its proportionate share of any man-
 agement fees and other expenses paid by such other investment companies.
 Such other investment companies will have investment objectives, policies
 and restrictions substantially similar to those of the acquiring Fund and
 will be subject to substantially the same risks.
 
 .STANDARD & POOR'S DEPOSITORY RECEIPTS. The Funds may, consistent with their
  investment policies, purchase Standard & Poor's Depository Receipts
  ("SPDRs"). SPDRs are securities traded on the American Stock Exchange
  ("AMEX") that represent ownership in the SPDR Trust, a trust which has been
  established to accumulate and hold a portfolio of common stocks that is
  intended to track the price performance and dividend yield of the S&P 500.
  The SPDR Trust is sponsored by a subsidiary of the AMEX. SPDRs may be used
  for several reasons, including, but not limited to, facilitating the han-
  dling of

                                                                      APPENDIX A
 
  cash flows or trading, or reducing transaction costs. The price movement of
  SPDRs may not perfectly parallel the price action of the S&P 500.
 
 .WORLD EQUITY BENCHMARK SHARES. World Equity Benchmark Shares ("WEBS") are
  shares of an investment company that invests substantially all of its
  assets in securities included in the MSCI indices for specified countries.
  WEBS are listed on the AMEX and were initially offered to the public in
  1996. The market prices of WEBS are expected to fluctuate in accordance
  with both changes in the NAVs of their underlying indices and supply and
  demand of WEBS on the AMEX. To date, WEBS have traded at relatively modest
  discounts and premiums to their NAVs. However, WEBS have a limited operat-
  ing history and information is lacking regarding the actual performance and
  trading liquidity of WEBS for extended periods or over complete market
  cycles. In addition, there is no assurance that the requirements of the
  AMEX necessary to maintain the listing of WEBS will continue to be met or
  will remain unchanged. In the event substantial market or other disruptions
  affecting WEBS should occur in the future, the liquidity and value of a
  Fund's shares could also be substantially and adversely affected. If such
  disruptions were to occur, a Fund could be required to reconsider the use
  of WEBS as part of its investment strategy.
 
 UNSEASONED COMPANIES. Each Fund may invest in companies (including predeces-
 sors) which have operated less than three years, except that this limitation
 does not apply to debt securities which have been rated investment grade or
 better by at least one NRSRO. The securities of such companies may have lim-
 ited liquidity, which can result in their being priced higher or lower than
 might otherwise be the case. In addition, investments in unseasoned compa-
 nies are more speculative and entail greater risk than do investments in
 companies with an established operating record.
 
 CORPORATE DEBT OBLIGATIONS. Corporate debt obligations include bonds, notes,
 debentures and other obligations of corporations to pay interest and repay
 principal, and include securities issued by banks and other financial insti-
 tutions. Each Fund may invest in corporate debt obligations issued by U.S.
 and certain non-U.S. issuers which issue securities denominated in the U.S.
 dollar (including Yankee and Euro obligations). In addition to obligations
 of corporations, corporate debt obligations include securities issued by
 banks and other financial institutions and supranational entities (i.e., the
 World Bank, the International Monetary Fund, etc.).
 
 BANK OBLIGATIONS. Each Fund may invest in obligations issued or guaranteed
 by U.S. or foreign banks. Bank obligations, including without limitations,
 time deposits, bankers' acceptances and certificates of deposit, may be gen-
 eral obligations of the parent bank or may be limited to the issuing branch
 by the terms of the specific obligations or by government regulations. Banks
 are subject to extensive but
 
                                                                              75
<PAGE>
 
 
 different governmental regulations which may limit both the amount and types
 of loans which may be made and interest rates which may be charged. In addi-
 tion, the profitability of the banking industry is largely dependent upon
 the availability and cost of funds for the purpose of financing lending
 operations under prevailing money market conditions. General economic condi-
 tions as well as exposure to credit losses arising from possible financial
 difficulties of borrowers play an important part in the operation of this
 industry.
 
 U.S. GOVERNMENT SECURITIES AND RELATED CUSTODIAL RECEIPTS. Each Fund may
 invest in U.S. government securities and related custodial receipts. U.S.
 government securities include U.S. Treasury obligations and obligations
 issued or guaranteed by U.S. government agencies, instrumentalities or spon-
 sored enterprises. U.S. government securities may be supported by (a) the
 full faith and credit of the U.S. Treasury (such as the Government National
 Mortgage Association ("Ginnie Mae")); (b) the right of the issuer to borrow
 from the U.S. Treasury (such as securities of the Student Loan Marketing
 Association); (c) the discretionary authority of the U.S. government to pur-
 chase certain obligations of the issuer (such as the Federal National Mort-
 gage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. government
 securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. government securities, where the interest and principal compo-
 nents of stripped U.S. government securities are traded independently.
 
 Interests in U.S. government securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S.
 government.
 
 MORTGAGE-BACKED SECURITIES. Certain Funds may invest in mortgage-backed
 securities. Mortgage-backed securities represent direct or indirect partici-
 pations in, or are collateralized by and payable from, mortgage loans
 secured by real property. Mortgage-backed securities can be backed by either
 fixed rate mortgage loans or adjustable rate mortgage loans, and may be
 issued by either a governmental or non-governmental entity. Privately issued
 mortgage-backed securities are normally structured with one or more types of
 "credit enhancement." However, these mortgage-backed securities typically do
 not have the same credit standing as U.S. government guaranteed mortgage-
 backed securities.
 
 Mortgage-backed securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an
 
76

                                                                      APPENDIX A
 
 investor with a specified interest in the cash flow from a pool of under-
 lying mortgages or of other mortgage-backed securities. CMOs are issued in
 multiple classes. In most cases, payments of principal are applied to the
 CMO classes in the order of their respective stated maturities, so that no
 principal payments will be made on a CMO class until all other classes hav-
 ing an earlier stated maturity date are paid in full. A REMIC is a CMO that
 qualifies for special tax treatment and invests in certain mortgages princi-
 pally secured by interests in real property and other permitted investments.
 
 Mortgaged-backed securities also include stripped mortgage-backed securities
 ("SMBS"), which are derivative multiple class mortgage-backed securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other mortgage-backed securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 ASSET-BACKED SECURITIES. Certain Funds may invest in asset-backed securi-
 ties. Asset-backed securities are securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed securities are often subject to more rapid repayment than their
 stated maturity date would indicate as a result of the pass-through of pre-
 payments of principal on the underlying loans. During periods of declining
 interest rates, prepayment of loans underlying asset-backed securities can
 be expected to accelerate. Accordingly, a Fund's ability to maintain posi-
 tions in such securities will be affected by reductions in the principal
 amount of such securities resulting from prepayments, and its ability to
 reinvest the returns of principal at comparable yields is subject to gener-
 ally prevailing interest rates at that time. Asset-backed securities present
 credit risks that are not presented by mortgage-backed securities. This is
 because asset-backed securities generally do not have the benefit of a secu-
 rity interest in collateral that is comparable to mortgage assets. There is
 the possibility that, in some cases, recoveries on repossessed collateral
 may not be available to support payments on these securities. In the event
 of a default, a Fund may suffer a loss if it cannot sell collateral quickly
 and receive the amount it is owed.
 
 BORROWINGS. Each Fund can borrow money from banks and other financial insti-
 tutions in amounts not exceeding one-third of their total assets for tempo-
 rary or emergency purposes. A Fund may not make additional investments if
 borrowings exceed 5% of its total assets.
 
                                                                              77
<PAGE>
 
 
 
MORTGAGE DOLLAR ROLLS. Certain Funds may enter into mortgage dollar rolls. A
mortgage dollar roll involves the sale by a Fund of securities for delivery in
the current month. The Fund simultaneously contracts with the same counterparty
to repurchase substantially similar (same type, coupon and maturity) but not
identical securities on a specified future date. During the roll period, the
Fund loses the right to receive principal and interest paid on the securities
sold. However, the Fund benefits to the extent of any difference between (a)
the price received for the securities sold and (b) the lower forward price for
the future purchase and/or fee income plus the interest earned on the cash pro-
ceeds of the securities sold. Unless the benefits of a mortgage dollar roll
exceed the income, capital appreciation and gain or loss due to mortgage pre-
payments that would have been realized on the securities sold as part of the
roll, the use of this technique will diminish the Fund's performance.
 
Successful use of mortgage dollar rolls depends upon the Investment Adviser's
ability to predict correctly interest rates and mortgage prepayments. If the
Investment Adviser is incorrect in its prediction, a Fund may experience a
loss. For financial reporting and tax purposes, the Funds treat mortgage dollar
rolls as two separate transactions: one involving the purchase of a security
and a separate transaction involving a sale. The Funds do not currently intend
to enter into mortgage dollar rolls that are accounted for as a financing and
do not treat them as borrowings.
 
YIELD CURVE OPTIONS. Certain Funds may enter into options on the yield "spread"
or differential between two securities. Such transactions are referred to as
"yield curve" options. In contrast to other types of options, a yield curve
option is based on the difference between the yields of designated securities,
rather than the prices of the individual securities, and is settled through
cash payments. Accordingly, a yield curve option is profitable to the holder if
this differential widens (in the case of a call) or narrows (in the case of a
put), regardless of whether the yields of the underlying securities increase or
decrease.
 
The trading of yield curve options is subject to all of the risks associated
with the trading of other types of options. In addition, such options present a
risk of loss even if the yield of one of the underlying securities remains con-
stant, or if the spread moves in a direction or to an extent which was not
anticipated.
 
REVERSE REPURCHASE AGREEMENTS. Certain Funds may enter into reverse repurchase
agreements. Reverse repurchase agreements involve the sale of securities held
by a Fund subject to the Fund's agreement to repurchase them at a mutually
agreed upon date and price (including interest). These transactions may be
entered into as a temporary measure for emergency purposes or to meet redemp-
tion requests. Reverse repurchase agreements may also be entered into when the
Investment Adviser expects that the interest income to be earned from the
investment of the transaction proceeds will
 
78
<PAGE>
 
                                                                      APPENDIX A
 
be greater than the related interest expense. Reverse repurchase agreements
involve leveraging. If the securities held by a Fund decline in value while
these transactions are outstanding, the NAV of the Fund's outstanding shares
will decline in value by proportionately more than the decline in value of the
securities. In addition, reverse repurchase agreements involve the risk that
the interest income earned by a Fund (from the investment of the proceeds) will
be less than the interest expense of the transaction, that the market value of
the securities sold by a Fund will decline below the price the Fund is obli-
gated to pay to repurchase the securities, and that the securities may not be
returned to the Fund.
 
MUNICIPAL SECURITIES. Certain Funds may invest in securities and instruments
issued by state and local government issuers. Municipal securities in which a
Fund may invest consist of bonds, notes, commercial paper and other instruments
(including participating interest in such securities) issued by or on behalf of
states, territories and possessions of the United States (including the Dis-
trict of Columbia) and their political subdivisions, agencies or instrumentali-
ties. Such securities may pay fixed, variable or floating rates of interest.
Municipal securities are often issued to obtain funds for various public pur-
poses, including the construction of a wide range of public facilities such as
bridges, highways, housing, hospitals, mass transportation, schools, streets
and water and sewer works. Other public purposes for which municipal securities
may be issued include refunding outstanding obligations, obtaining funds for
general operating expenses, and obtaining funds to lend to other public insti-
tutions and facilities. Municipal securities in which a Fund may invest include
private activity bonds, municipal leases, certificates of participation, pre-
funded municipal securities and auction rate securities.
 
INTEREST RATE SWAPS, MORTGAGE SWAPS, CREDIT SWAPS, CURRENCY SWAPS AND INTEREST
RATE CAPS, FLOORS AND COLLARS. Interest rate swaps involve the exchange by a
Fund with another party of their respective commitments to pay or receive
interest, such as an exchange of fixed-rate payments for floating rate pay-
ments. Mortgage swaps are similar to interest rate swaps in that they represent
commitments to pay and receive interest. The notional principal amount, howev-
er, is tied to a reference pool or pools of mortgages. Credit swaps involve the
receipt of floating or fixed rate payments in exchange for assuming potential
credit losses of an underlying security. Credit swaps give one party to a
transaction the right to dispose of or acquire an asset (or group of assets),
or the right to receive or make a payment from the other party, upon the occur-
rence of specified credit events. Currency swaps involve the exchange of the
parties' respective rights to make or receive payments in specified currencies.
The purchase of an interest rate cap entitles the purchaser, to the extent that
a specified index exceeds a predetermined interest rate, to receive payment of
interest on a notional principal amount from the party selling such interest
rate cap. The purchase
 
                                                                              79
<PAGE>
 
 
of an interest rate floor entitles the purchaser, to the extent that a speci-
fied index falls below a predetermined interest rate, to receive payments of
interest on a notional principal amount from the party selling the interest
rate floor. An interest rate collar is the combination of a cap and a floor
that preserves a certain return within a predetermined range of interest rates.
 
Certain Funds may enter into swap transactions for hedging purposes or to seek
to increase total return. The use of interest rate, mortgage, credit and cur-
rency swaps, as well as interest rate caps, floors and collars, is a highly
specialized activity which involves investment techniques and risks different
from those associated with ordinary portfolio securities transactions. If the
Investment Adviser is incorrect in its forecasts of market value, interest
rates and currency exchange rates, the investment performance of a Fund would
be less favorable than it would have been if these investment techniques were
not used.
 
LOAN PARTICIPATIONS. Certain Funds may invest in loan participations. A loan
participation is an interest in a loan to a U.S. or foreign company or other
borrower which is administered and sold by a financial intermediary. A Fund may
only invest in loans to issuers in whose obligations it may otherwise invest.
Loan participation interests may take the form of a direct or co-lending rela-
tionship with the corporate borrower, an assignment of an interest in the loan
by a co-lender or another participant, or a participation in the seller's share
of the loan. When a Fund acts as co-lender in connection with a participation
interest or when it acquires certain participation interests, the Fund will
have direct recourse against the borrower if the borrower fails to pay sched-
uled principal and interest. In cases where the Fund lacks direct recourse, it
will look to the agent bank to enforce appropriate credit remedies against the
borrower. In these cases, the Fund may be subject to delays, expenses and risks
that are greater than those that would have been involved if the Fund had pur-
chased a direct obligation (such as commercial paper) of such borrower. More-
over, under the terms of the loan participation, the Fund may be regarded as a
creditor of the agent bank (rather than of the underlying corporate borrower),
so that the Fund may also be subject to the risk that the agent bank may become
insolvent.
 
INVERSE FLOATERS. Certain Funds may invest in inverse floating rate debt secu-
rities ("inverse floaters"). The interest rate on inverse floaters resets in
the opposite direction from the market rate of interest to which the inverse
floater is indexed. An inverse floater may be considered to be leveraged to the
extent that its interest rate varies by a magnitude that exceeds the magnitude
of the change in the index rate of interest. The higher the degree of leverage
of an inverse floater, the greater the volatility of its market value.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has not
 been in operation for less than five years). Certain information reflects
 financial results for a single Fund share. The total returns in the table
 represent the rate that an investor would have earned or lost on an invest-
 ment in a Fund (assuming reinvestment of all dividends and distributions).
 This information has been audited by Arthur Andersen LLP, whose report,
 along with a Fund's financial statements, is included in the Fund's annual
 report (available upon request).

Prior Performance of Similarly Advised Accounts of the Investment Adviser
 
 CORE LARGE CAP VALUE FUND
 
 The following table sets forth the Investment Adviser's composite perfor-
 mance data relating to the historical performance of all discretionary pri-
 vate accounts managed by the Investment Adviser that have investment objec-
 tives, policies, and strategies substantially similar to the CORE Large Cap
 Value Fund. The information is provided to illustrate the past performance
 of the Investment Adviser in managing substantially similar accounts as mea-
 sured against the Russell 1000 Value Index and does not represent the per-
 formance of the CORE Large Cap Value Fund. Investors should not consider
 this performance data as a substitute for the performance of the CORE Large
 Cap Value Fund nor should investors consider this data as an indication of
 future performance of the CORE Large Cap Value Fund or of the Investment
 Adviser. The Russell 1000 Value Index is unmanaged and investors cannot
 invest directly in the Index.

 information was calculated on a time-weighted and asset-weighted total
 return basis which includes realized and unrealized gains and losses plus
 income. The composite performance is net of applicable investment management
 fees, brokerage commissions, execution costs and custodial fees, without
 provision for federal and state taxes, if any. Total return performance of
 the CORE Large Cap Value Fund will be calculated in accordance with the reg-
 ulations of the SEC. The SEC standardized average annual total return is
 neither time-weighted nor asset-weighted and is determined for specified
 periods by computing the annualized percentage change in the value of an
 initial amount that is invested in a share class of the Fund at the maximum
 public offering price. Investors should be aware that the differences in
 methodology between AIMR and SEC requirements could result in different per-
 formance data for identical time periods.
 
 All returns presented reflect the reinvestment of dividends and other earn-
 ings. The weighted-average expenses of the private accounts used in calcu-
 lating the Investment Adviser's net composite performance data were 0.59%
 annualized, which are lower than the estimated expenses of Institutional
 Shares of the CORE Large Cap Value Fund stated under "Fund Fees and
 Expenses" above. The performance of the private accounts would have been
 lower if they had been subject to the expenses of the CORE Large Cap Value
 Fund. In addition, the private accounts are not subject to the same diversi-
 fication requirements, specific tax restrictions and investment limitations
 imposed on the CORE Large Cap Value Fund by the Act and Subchapter M of the
 Code. Consequently, the performance results of the Investment Adviser's com-
 posite could have been adversely affected if the private accounts had been
 regulated as investment companies under the federal securities laws.

 The following table sets forth the Investment Adviser's composite perfor-

 vate accounts managed by the Investment Adviser that have investment objec-
 tives, policies, and strategies substantially similar to the Strategic
 Growth Fund. The information is provided to illustrate the past performance
 of the Investment Adviser in managing substantially similar accounts as mea-
 sured against the S&P 500 Index and does not represent the performance of
 the Strategic Growth Fund. Investors should not consider this performance
 data as a substitute for the performance of the Strategic Growth Fund nor
 should investors consider this data as an indication of future performance
 of the Strategic Growth Fund or of the Investment Adviser. The S&P 500 Index
 is unmanaged and investors cannot invest directly in the Index.

 All returns presented reflect the reinvestment of dividends and other earn-

 the performance results of the Investment Adviser's composite could have

 The Investment Adviser attempts to manage risk in these Funds through disci-
 plined portfolio construction and continual portfolio review and analysis.
 As a result, bottom-up stock selection, driven by fundamental research,
 should be a main driver of returns.

 QUANTITATIVE ("CORE") STYLE FUNDS
 
 
 Goldman Sachs' CORE Investment Philosophy:
 Goldman Sachs' quantitative style of funds--CORE--emphasizes the two build-
 ing blocks of active management: STOCK SELECTION and PORTFOLIO CONSTRUCTION.
 
 I. Core Stock Selection
 The CORE Funds use the Goldman Sachs proprietary multifactor model
 ("Multifactor Model"), a rigorous computerized rating system, to forecast
 returns on securities held in each Fund's portfolio. The Multifactor Model
 incorporates common variables covering measures of:
 .VALUE (price-to-book, price-to-earnings, cash flow to enterprise value)
 .MOMENTUM (earnings momentum, price momentum, sustainable growth)
 .RISK (market risk, company-specific risk, earnings risk)
 
 ALL OF THE ABOVE FACTORS ARE CAREFULLY EVALUATED WITHIN THE MULTIFACTOR
 MODEL SINCE EACH HAS DEMONSTRATED A SIGNIFICANT IMPACT ON THE PERFORMANCE OF
 THE SECURITIES AND MARKETS THEY WERE DESIGNED TO FORECAST.
 
 II. Core Portfolio Construction
 A proprietary COMPUTER OPTIMIZER calculates every security combination (at
 every possible weighting) to CONSTRUCT THE MOST EFFICIENT RISK/RETURN PORT-
 FOLIO given each CORE Fund benchmark. In this process, the Investment
 Adviser manages risk by limiting deviations from the benchmark.
 
 Goldman Sachs CORE Funds are fully invested, broadly diversified and offer
 consistent overall portfolio characteristics. They may serve as good founda-
 tions on which to build a portfolio.

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term growth of capital. The Fund seeks this objective
 through a broadly diversified portfolio of equity securities of large-cap
 companies that are organized outside the United States or whose securities
 are principally traded outside the United States.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, at least
 90% of its total assets in equity securities of companies that are organized
 outside the United States or whose securities are principally traded outside
 the United States.
 
 The Fund may allocate its assets among countries as determined by the
 Investment Adviser from time to time, provided the Fund's assets are
 invested in at least three foreign countries. The Fund may invest in the
 securities of issuers in countries with emerging markets or economies
 ("emerging countries").
 
 The Fund seeks broad representation of large-cap issuers across major coun-
 tries and sectors of the international economy. The Fund's investments are
 selected using both a variety of quantitative techniques and fundamental
 research in seeking to maximize the Fund's expected return, while maintain-
 ing risk, style, capitalization and industry characteristics similar to the
 EAFE Index. In addition, the Fund seeks a portfolio composed of companies
 with attractive valuations and stronger momentum characteristics than the
 EAFE Index.
 
 Other. The Fund's investments in fixed-income securities are limited to
 securities that are considered to be cash equivalents.

 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 companies that are organized outside the United States or whose securities
 are principally traded outside the United States. The Fund intends to invest
 in companies with public stock market capitalizations that are larger than
 $1 billion at the time of investment.
 
 The Fund may allocate its assets among countries as determined by the
 Investment Adviser from time to time provided that the Fund's assets are
 invested in at least three foreign countries.
 
 The Fund expects to invest a substantial portion of its assets in the secu-
 rities of issuers located in the developed countries of Western Europe and
 in Japan. However, the Fund may also invest in the securities of issuers
 located in Australia, Canada, New Zealand and in emerging countries. Cur-
 rently, emerging countries include, among others, most Latin American, Afri-
 can, Asian and Eastern European nations.
 
 Other. The Fund may also invest up to 35% of its total assets in fixed-
 income securities, such as corporate debt and bank obligations.

 INVESTMENT OBJECTIVE
 
 The Fund seeks long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 European companies. Because of its focus, the Fund will be more susceptible
 to European economic, market, political and local risks than a fund that is
 more geographically diversified.
 
 A European issuer is a company that either:
 .Has a class of its securities whose principal securities markets is in a
  European country;
 .Is organized under the laws of, or has a principal office in, a European
  country;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in one or more of the European countries; or
 .Maintains 50% or more of its assets in one or more of the European coun-
  tries.
 
 The Fund may allocate its assets among different countries as determined by
 the Investment Adviser from time to time, provided that the Fund's assets
 are invested in at least three European countries. It is currently antici-
 pated that a majority of the Fund's assets will be invested in the equity
 securities of large cap companies located in the developed countries of
 Western Europe. However, the Fund may also invest, without limit, in mid cap
 companies and small cap companies, as well as companies located in emerging
 countries. Currently, emerging countries include among others, most Latin
 American, African, Asian, most Eastern European nations, including the
 states that formerly comprised the Soviet Union and Yugoslavia.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of non-European countries and in fixed-income securities,
 such as corporate debt and bank obligations.

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 Japanese companies. A Japanese issuer is a company that either:
 .Has a class of its securities whose principal securities markets is in
  Japan;
 .Is organized under the laws of, or has a principal office in Japan;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in Japan; or
 .Maintains 50% or more of its assets in Japan.
 
 The Fund's concentration in Japanese companies will expose it to the risk of
 adverse social, political and economic events which occur in Japan or affect
 the Japanese markets.
 
 Japan's economy, the second largest in the world, has grown substantially
 over the last three decades. Since 1990, however, Japan's economic growth
 has declined significantly, and is currently subject to deflationary pres-
 sures. In addition to this economic downturn, Japan is undergoing structural
 adjustments related to high wages and taxes, currency valuations and struc-
 tural rigidities. Japan has also been experiencing notable uncertainty and
 loss of public confidence in connection with the reform of its political
 process and the deregulation of its economy. These conditions present risks
 to the Japanese Equity Fund and its ability to attain its investment objec-
 tive.

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
 
 
 
 Japan's economy is heavily dependent upon international trade, and is espe-
 cially sensitive to trade barriers and disputes. In particular, Japan relies
 on large imports of agricultural products, raw materials and fuels. A sub-
 stantial rise in world oil or commodity prices, or a fall-off in Japan's
 manufactured exports, could be expected to adversely affect Japan's economy.
 In addition, Japan is vulnerable to earthquakes, volcanoes and other natural
 disasters. As of the date of this Prospectus, Japan's banking industry con-
 tinued to suffer from non-performing loans, declining real estate values and
 lower valuations of securities holdings.
 
 The Japanese securities markets are less regulated than the U.S. markets.
 Evidence has emerged from time to time of distortion of market prices to
 serve political or other purposes. Shareholders' rights are also not always
 equally enforced.
 
 The common stocks of many Japanese companies trade at high price-earnings
 ratios. Differences in accounting methods make it difficult to compare the
 earnings of Japanese companies with those of companies in other countries,
 especially the United States. In general, however, reported net income in
 Japan is understated relative to U.S. accounting standards and this is one
 reason price-earnings ratios of the stocks of Japanese companies have tended
 historically to be higher than those of U.S. stocks. In addition, Japanese
 companies have tended to have higher growth rates than U.S. companies, and
 Japanese interest rates have generally been lower than U.S. interest rates.
 These factors have contributed to lower discount rates and higher price-
 earnings ratios in Japan than in the United States.
 
 During the recent past the average stock market prices of Japanese compa-
 nies, as measured by major indices such as the NIKKEI 225 Average, have
 experienced a substantial decline. It is not possible to determine whether
 this general decline will continue.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of non-Japanese companies and in fixed-income securities,
 such as corporate debt and bank obligations.

 izations of more than $1 billion at the time of investment and in fixed-
 income securities, such as corporate debt and bank obligations. If the mar-
 ket capitalization of a company held by the Fund increases above $1 billion,
 the Fund may, consistent with its investment objective, continue to hold the
 security.

 Equity Securities. The Fund invests, under normal circumstances, substan-

 emerging country issuers. The Investment Adviser may consider classifica-
 tions by the World Bank, the International Finance Corporation or the United
 Nations and its agencies in determining whether a country is emerging or
 developed. Currently, emerging countries include, among others, most Latin
 American, African, Asian and Eastern European nations. The Investment
 Adviser currently intends that the Fund's investment focus will be in the
 following emerging countries as well as any other emerging country to the
 extent that foreign investors are permitted by applicable law to make such
 investments:

Goldman Sachs Emerging Markets Equity Fund continued
 
 
 An emerging country issuer is any company that either:
 .Has a class of its securities whose principal securities market is in an
  emerging country;
 .Is organized under the laws of, or has a principal office in, an emerging
  country;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in one or more emerging countries; or
 .Maintains 50% or more of its assets in one or more of the emerging coun-
  tries.
 
 Under normal circumstances, the Fund maintains investments in at least six
 emerging countries, and will not invest more than 35% of its total assets in
 securities of issuers in any one emerging country. Allocation of the Fund's
 investments will depend upon the relative attractiveness of the emerging
 country markets and particular issuers. In addition, macro-economic factors
 and the portfolio managers' and Goldman Sachs economists' views of the rela-
 tive attractiveness of emerging countries and currencies are considered in
 allocating the Fund's assets among emerging countries.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 (i) fixed-income securities, such as corporate debt and bank obligations, of
 private and governmental emerging country issuers; and (ii) equity and
 fixed-income securities, such as corporate debt and bank obligations, of
 issuers in developed countries.

 Equity Securities. The Fund invests, under normal circumstances, substan-

 Asian issuers.
 An Asian issuer is any company that either:
 .Has a class of its securities whose principal securities markets is in one
  or more Asian countries;
 .Is organized under the laws of, or has a principal office in, an Asian
  country;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in one or more Asian countries; or
 .Maintains 50% or more of its assets in one or more Asian countries.
 
 The Fund may allocate its assets among the Asian countries as determined
 from time to time by the Investment Adviser. For purposes of the Fund's
 investment policies, Asian countries are:
 .China               .Malaysia           .South Korea
 .Hong Kong           .Pakistan           .Sri Lanka
 .India               .Philippines        .Taiwan
 .Indonesia           .Singapore          .Thailand
 
 as well as any other country in Asia (other than Japan) to the extent that
 foreign investors are permitted by applicable law to make such investments.
 
                                                                              11

Goldman Sachs Asia Growth Fund continued
 
 
 Allocation of the Fund's investments will depend upon the Investment Advis-
 er's views of the relative attractiveness of the Asian markets and particu-
 lar issuers.
 
 Concentration of the Fund's assets in one or a few of the Asian countries
 and Asian currencies will subject the Fund to greater risks than if the
 Fund's assets were not so concentrated. For example, on January 31, 1999
 (the end of the Fund's last fiscal year), more than 25% of the Fund's assets
 were invested in securities that traded in Hong Kong.
 
 Starting in mid-1997 some Pacific region countries began to experience cur-
 rency devaluations that resulted in high interest rate levels and sharp
 reductions in economic activity. This situation resulted in a significant
 drop in the securities prices of companies located in the region. Some coun-
 tries have experienced government intervention, have sought assistance from
 the International Monetary Fund and are undergoing substantial domestic
 unrest. Although some countries are taking steps to restructure their finan-
 cial sectors in a manner that may facilitate a return to long-term economic
 growth, there can be no assurance that these efforts will be successful or
 that their current problems will not persist. At the end of its last fiscal
 year, a substantial portion of the Asia Growth Fund was invested in securi-
 ties traded in the Hong Kong market. In 1997, the sovereignty of Hong Kong
 reverted from the United Kingdom to China. Although Hong Kong is, by law, to
 maintain a high degree of autonomy, there can also be no assurance that the
 general economic position of Hong Kong will not be adversely affected as a
 result of the exercise of Chinese sovereignty over Hong Kong. In particular,
 business confidence in Hong Kong can be significantly affected by political
 developments and statements by public figures in China, which can in turn
 affect the performance of the securities markets. In addition, the reversion
 of Hong Kong to China has created uncertainty as to future currency valua-
 tions relative to the U.S. dollar. Any future valuation changes could be
 adverse from the perspective of U.S. investors.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of issuers in other countries, including Japan, and in
 fixed-income securities, such as corporate debt and bank obligations.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete
investment program. There can be no assurance that a Fund will achieve its
investment objective.

 .EMERGING COUNTRIES RISK--The securities markets of Asian, Latin American,
 Eastern European, African and other emerging countries are less liquid, are
 especially subject to greater price volatility, have smaller market capital-
 izations, have less government regulation and are not subject to as extensive
 and frequent accounting, financial and other reporting requirements as the
 securities markets of more developed countries. Further, investment in equity
 securities of issuers located in Russia and certain other emerging countries
 involves risk of loss resulting from problems in share registration and cus-
 tody and substantial economic and political disrup-

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 tions. These risks are not normally associated with investment in more devel-
 oped countries.
 .INTEREST RATE RISK--The risk that when interest rates increase, fixed-income
 securities held by a Fund will decline in value. Long-term fixed-income secu-
 rities will normally have more price volatility because of this risk than
 short-term securities.
 .FOREIGN RISKS--The risk that when a Fund invests in foreign securities, it
 will be subject to risks not typically associated with domestic issuers. Loss
 may result because of less foreign government regulation, less public informa-
 tion and less economic, political and social stability. Loss may also result
 from the imposition of exchange controls, confiscations and other government
 restrictions. A Fund will also be subject to the risk of negative foreign cur-
 rency rate fluctuations. Foreign risks will normally be greatest when a Fund
 invests in issuers located in emerging countries.
 .DERIVATIVES RISK--The risk that loss may result from a Fund's investments in
 options, futures, swaps, structured securities and other derivative instru-
 ments. These instruments may be leveraged so that small changes may produce
 disproportionate losses to a Fund.
 .MANAGEMENT RISK--The risk that a strategy used by the Investment Adviser may
 fail to produce the intended results.
 .MARKET RISK--The risk that the value of the securities in which a Fund invests
 may go up or down in response to the prospects of individual companies and/or
 general economic conditions. Price changes may be temporary or last for
 extended periods.
 .LIQUIDITY RISK--The risk that a Fund will not be able to pay redemption pro-
 ceeds within the time period stated in this Prospectus, because of unusual
 market conditions, an unusually high volume of redemption requests, or other
 reasons. Funds that invest in small capitalization stocks and emerging country
 issuers will be especially subject to the risk that during certain periods the
 liquidity of particular issuers or industries, or all securities within these
 investment categories, will shrink or disappear suddenly and without warning
 as a result of adverse economic, market or political events, or adverse
 investor perceptions whether or not accurate.
 .STOCK RISK--The risk that stock prices have historically risen and fallen in
 periodic cycles. As of the date of this Prospectus, U.S. stock markets and
 certain foreign stock markets were trading at or close to record high levels.
 There is no guarantee that such levels will continue.
 .OTHER RISKS--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
                                                                              19
<PAGE>
 
 
Specific Funds:
 
 .SMALL CAP STOCK RISK--The securities of small capitalization stocks involve
 greater risks than those associated with larger, more established companies
 and may be subject to more abrupt or erratic price movements. Securities of
 such issuers may lack sufficient market liquidity to enable a Fund to effect
 sales at an advantageous time or without a substantial drop in price.
 .GEOGRAPHIC RISK--The European Equity Fund invests primarily in equity securi-
 ties of European companies. The Japanese Equity Fund invests primarily in
 equity securities of Japanese equity companies. The Asia Growth Fund invests
 primarily in equity securities of Asian issuers. Concentration of the invest-
 ments of these or other Funds in issuers located in a particular country or
 region will subject the Fund, to a greater extent than if investments were
 less concentrated, to the risks of adverse securities markets, exchange rates
 and social, political, regulatory or economic events which may occur in that
 country or region.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Class A
 Shares from year to year; and (b) how the average annual returns of a Fund's
 Class A, B and C Shares compare to those of broad-based securities market
 indices. The bar chart and table assume reinvestment of dividends and dis-
 tributions. A Fund's past performance is not necessarily an indication of
 how the Fund will perform in the future. The average annual total return
 calculation reflects a maximum initial sales charge of 5.5% for Class A
 Shares, the assumed contingent deferred sales charge ("CDSC") for Class B
 Shares (5% maximum declining to 0% after six years), and the assumed CDSC
 for Class C Shares (1% if redeemed within 12 months of purchase). The bar
 chart does not reflect the sales loads applicable to Class A Shares. If the
 sales loads were reflected, returns would be less. Performance reflects
 expense limitations in effect. If expense limitations were not in place, a
 Fund's performance would have been reduced. The European Equity, Japanese
 Equity and International Small Cap Funds did not commence operations until
 October 1, 1998, May 1, 1998 and May 1, 1998. Since these Funds have less
 than one calendar year's performance, no performance information is provided
 in this section.

                                                          FUND FEES AND EXPENSES
 
 
/1/The maximum sales charge is a percentage of the offering price. A CDSC of 1%
is imposed on certain redemptions (within 18 months of purchase) of Class A
Shares sold without an initial sales charge as part of an investment of $1 mil-
lion or more.
/2/The maximum CDSC is a percentage of the lesser of the net asset value
("NAV") at the time of the redemption or the NAV when the shares were origi-
nally purchased.
/3/A CDSC is imposed upon Class B Shares redeemed within six years of purchase
at a rate of 5% in the first year, declining to 1% in the sixth year, and elim-
inated thereafter.
/4/A CDSC of 1% is imposed on Class C Shares redeemed within 12 months of pur-
chase.
/5/A transaction fee of $7.50 may be charged for redemption proceeds paid by
wire. In addition to free reinvestments of dividends and distributions in
shares of other Goldman Sachs Funds or shares of the Goldman Sachs Institu-
tional Liquid Assets Portfolios (the "ILA Portfolios") and free automatic
exchanges pursuant to the Automatic Exchange Program, six free exchanges are
permitted in each 12- month period. A fee of $12.50 may be charged for each
subsequent exchange during such period.
/6/The Funds' annual operating expenses have been restated to reflect current
fees, except for the European Equity Fund, Japanese Equity Fund and Interna-
tional Small Cap Fund whose expenses have been annualized for the current fis-
cal year.
/7/"Other Expenses" include transfer agency fees equal to 0.19% of the average
daily net assets of each Fund's Class A, B and C Shares, plus all other ordi-
nary expenses not detailed above. The Investment Adviser has voluntarily agreed
to reduce or limit certain "Other Expenses" (excluding management fees, distri-
bution and service fees, transfer agency fees, taxes, interest and brokerage
fees and litigation, indemnification and other extraordinary expenses) to the
following percentages of each Fund's average daily net assets:

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without expense limitations) with the cost of investing in other mutual
funds. The Example assumes that you invest $10,000 in Class A, B or C Shares of
a Fund for the time periods indicated and then redeem all of your shares at the
end of those periods. The Example also assumes that your investment has a 5%
return each year and that a Fund's operating expenses remain the same. Although
your actual costs may be higher or lower, based on these assumptions your costs
would be:

The hypothetical example assumes that a CDSC will not apply to redemptions of
Class A Shares within the first 18 months. Class B Shares convert to Class A
Shares eight years after purchase; therefore, Class A expenses are used in the
hypothetical example after year eight.
Certain institutions and/or their salespersons may receive other compensation
in connection with the sale and distribution of Class A, Class B and Class C
Shares for services to their customers' accounts and/or the Funds. For

 GSAM is a separate operating division of Goldman Sachs, which registered as
 an investment adviser in 1981. GSAMI, a member of the Investment Management
 Regulatory Organization Limited since 1990 and a registered investment
 adviser since 1991, is an affiliate of Goldman Sachs. The Goldman Sachs
 Group, L.P., which controls the Investment Advisers, announced that it will
 pursue an initial public offering of the firm in the late spring or early
 summer of 1999. Simultaneously with the offering, the Goldman Sachs Group,
 L.P. will merge into The Goldman Sachs Group, Inc. As of February 28, 1999,
 GSAM and GSAMI, together with their affiliates, acted as investment adviser
 or distributor for assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser makes the investment decisions
 for the Funds and places purchase and sale orders for the Funds' portfolio
 transactions in U.S. and foreign markets. As permitted by applicable law,
 these orders may be directed to any brokers, including Goldman Sachs and its
 affiliates. While the Investment Adviser is ultimately responsible for the
 management of the Funds, it is able to draw upon the research and expertise
 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.
 
 The Investment Adviser also performs the following additional services for
 the Funds:
 .Supervises all non-advisory operations of the Funds

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that a Fund
 could sustain losses during periods in which Goldman Sachs and its affili-
 ates and other accounts achieve significant profits on their trading for
 proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly

                                                               SERVICE PROVIDERS
 
 known as the "Year 2000 Problem"). To the extent these systems conduct
 forward-looking calculations, these computer problems may occur prior to
 January 1, 2000. Like other investment companies and financial and business
 organizations, the Funds could be adversely affected in their ability to
 process securities trades, price securities, provide shareholder account
 services and otherwise conduct normal business operations if the Investment
 Adviser or other Fund service providers do not adequately address this prob-
 lem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
                                                                              45

Dividends
 
 Each Fund pays dividends from its net investment income and distributions
 from net realized capital gains. You may choose to have dividends and dis-
 tributions paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund.
  Special restrictions may apply for certain ILA Portfolios. See the
  Additional Statement.
 
 You may indicate your election on your Account Application. Any changes may
 be submitted in writing to Goldman Sachs at any time before the record date
 for a particular dividend or distribution. If you do not indicate any
 choice, your dividends and distributions will be reinvested automatically in
 the applicable Fund.
 
 The election to reinvest dividends and distributions in additional shares
 will not affect the tax treatment of such dividends and distributions, which
 will be treated as received by you and then used to purchase the shares.
 Under certain circumstances, the Funds may make an election to treat a pro-
 portionate amount of such taxes as constituting a distribution to you, which
 would allow you either (1) to credit such proportionate amount of taxes
 against your U.S. federal income tax liability or (2) to take such amount as
 an itemized deduction.
 
 Dividends from net investment income and distributions from net capital
 gains are declared and paid annually.
 
 From time to time a portion of a Fund's dividends may constitute a return
 of capital.
 
 At the time of an investor's purchase of shares of a Fund, a portion of the
 NAV per share may be represented by undistributed income or realized or
 unrealized appreciation of the Fund's portfolio securities. Therefore, sub-
 sequent distributions on such shares from such income or realized apprecia-
 tion may be taxable to you even if the NAV of the shares is, as a result of
 the distributions, reduced below the cost of such shares and the distribu-
 tions (or portions thereof) represent a return of a portion of the purchase
 price.

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Refuse to open an account if you fail to (i) provide a social security num-

  frequent purchases, sales or exchanges of shares of a Fund is evident, or
  if purchases, sales or exchanges are, or a subsequent abrupt redemption
  might be, of a size that would disrupt management of a Fund.
 .Modify or waive the minimum investment amounts.
 .Modify the manner in which shares are offered.
 .Modify the sales charge rates applicable to future purchases of shares.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange shares is deter-
 mined by a Fund's NAV and share class. Each class calculates its NAV as fol-
 lows:
 
                     (Value of Assets of the Class)
                      - (Liabilities of the Class)
           NAV = _________________________________________
                 Number of Outstanding Shares of the Class
 
 The Funds' investments are valued based on market quotations or if accurate
 quotations are not readily available, the fair value of the Fund's invest-
 ments may be determined in good faith under procedures established by the
 Trustees.
 
 .NAV per share of each share class is calculated by the Fund's custodian on
  each business day as of the close of regular trading on the New York Stock
  Exchange (normally 4:00 p.m. New York time). Fund shares will not be priced
  on any day the New York Stock Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form, plus any applicable sales charge.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form, less any applicable CDSC.
 
 NOTE: THE TIME AT WHICH TRANSACTIONS AND SHARES ARE PRICED AND THE TIME BY
 WHICH ORDERS MUST BE RECEIVED MAY BE CHANGED IN CASE OF AN EMERGENCY OR IF
 REGULAR TRADING ON THE NEW YORK STOCK EXCHANGE IS STOPPED AT A TIME OTHER
 THAN 4:00 P.M. NEW YORK TIME.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 In addition, the impact of events that occur after the publication of market
 quotations used by a Fund to price its securities but before the close of
 regular trading on the New York Stock Exchange will normally not be
 reflected in a Fund's next
 
                                                                              49

 determined NAV unless the Trust, in its discretion, makes an adjustment in
 light of the nature and materiality of the event, its effect on Fund opera-
 tions and other relevant factors.
 
 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS A SHARES
 
 What Is The Offering Price Of Class A Shares?
 THE OFFERING PRICE OF CLASS A SHARES OF EACH FUND IS THE NEXT DETERMINED NAV
 PER SHARE PLUS AN INITIAL SALES CHARGE PAID TO GOLDMAN SACHS AT THE TIME OF
 PURCHASE OF SHARES. The sales charge varies depending upon the amount you
 purchase. In some cases, described below, the initial sales charge may be
 eliminated altogether, and the offering price will be the NAV per share. The
 current sales charges and commissions paid to Authorized Dealers are as fol-
 lows:

     Authorized Dealers to whom substantially the entire sales charge is
     allowed may be deemed to be "underwriters" under the Securities Act of
     1933.
  ** No sales charge is payable at the time of purchase of Class A Shares of
     $1 million or more, but a CDSC of 1% may be imposed in the event of cer-
     tain redemptions within 18 months of purchase.
 *** The Distributor pays a one-time commission to Authorized Dealers who

     shares of the Funds equal to 1.00% of the amount under $3 million, 0.50%

     initiate or are responsible for purchases of $500,000 or more by certain

     plans will be made at NAV with no initial sales charge, but if all of
     the shares held are redeemed within 18 months after the end of the cal-
     endar month in which such purchase was made, a CDSC of 1% may be imposed
     upon the plan sponsor or the third party administrator. In addition,
     Authorized Dealers will remit to the Distributor such payments received
     in connection with "wrap" accounts in the event that shares are redeemed
     within 18 months after the end of the calendar month in which the pur-
     chase was made.

 What Else Do I Need To Know About Class A Shares' CDSC?
 Purchases of $1 million or more of Class A Shares will be made at NAV with
 no initial sales charge. However, if you redeem shares within 18 months
 after the end of the calendar month in which the purchase was made, exclud-
 ing any period of time in which the shares were exchanged into and remained
 invested in an equivalent class of an ILA Portfolio, a CDSC of 1% may be
 imposed. The CDSC may not be imposed if your Authorized Dealer enters into
 an agreement with the Distributor to return all or an applicable prorated
 portion of its commission to the Distributor. The CDSC is waived on redemp-
 tions in certain circumstances. See "In What Situations May The CDSC On
 Class A, B Or C Shares Be Waived Or Reduced?" below.
 
 When Are Class A Shares Not Subject To A Sales Load?

  invested in the Goldman Sachs Funds and reinvesting such proceeds in a
  Goldman Sachs IRA.
 
 YOU MUST CERTIFY ELIGIBILITY FOR ANY OF THE ABOVE EXEMPTIONS ON YOUR ACCOUNT
 APPLICATION AND NOTIFY THE FUND IF YOU NO LONGER ARE ELIGIBLE FOR THE EXEMP-
 TION. The Fund will grant you an exemption subject to confirmation of your
 entitlement. You may be charged a fee if you effect your transactions
 through a broker or agent.
 
 How Can The Sales Charge On Class A Shares Be Reduced?
 .RIGHT OF ACCUMULATION: When buying Class A Shares in Goldman Sachs Funds,
  your current aggregate investment determines the initial sales load you
  pay. You may qualify for reduced sales charges when the current market
  value of holdings (shares at current offering price), plus new purchases,
  reaches $50,000 or more. Class A Shares of any of the Goldman Sachs Funds
  may be combined under the Right of Accumulation. To qualify for a reduced
  sales load, you or your Authorized Dealer must notify the Funds' Transfer
  Agent at the time of investment that a quantity discount is applicable. Use
  of this service is subject to a check of appropriate records. The Addi-
  tional Statement has more information about the Right of Accumulation.
 .STATEMENT OF INTENTION: You may obtain a reduced sales charge by means of a
  written Statement of Intention which expresses your non-binding commitment
  to invest in the aggregate $50,000 or more (not counting reinvestments of
  dividends and distributions) within a period of 13 months in Class A Shares
  of one or more Goldman Sachs Fund. Any investments you make during the
  period will receive the discounted sales load based on the full amount of
  your investment commitment. If the investment commitment of the Statement
  of Intention is not met prior to the expiration of the 13-month period, the
  entire amount will be subject to the higher applicable sales charge. By
  signing the Statement of Intention, you authorize the Transfer Agent to
  escrow and redeem Class A Shares in your account to pay this additional
  charge. The Additional Statement has more information about the Statement
  of Intention, which you should read carefully.

 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS B SHARES
 
 
 What Is The Offering Price Of Class B Shares?
 YOU MAY PURCHASE CLASS B SHARES OF THE FUNDS AT THE NEXT DETERMINED NAV
 WITHOUT AN INITIAL SALES CHARGE. HOWEVER, CLASS B SHARES REDEEMED WITHIN SIX
 YEARS OF PURCHASE WILL BE SUBJECT TO A CDSC AT THE RATES SHOWN IN THE TABLE
 BELOW BASED ON HOW LONG YOU HELD YOUR SHARES.
 
 The CDSC schedule is as follows:

                           DOLLAR AMOUNT

  Seventh and thereafter       None
 ----------------------------------------
</TABLE>
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class B Shares, including the payment of compensation to Authorized Dealers.
 A commission equal to 4% of the amount invested is paid to Authorized Deal-
 ers.
 
 What Should I Know About The Automatic Conversion Of Class B Shares?
 Class B Shares of a Fund will automatically convert into Class A Shares of
 the same Fund at the end of the calendar quarter that is eight years after
 the purchase date.
 
 If you acquire Class B Shares of a Fund by exchange from Class B Shares of
 another Goldman Sachs Fund, your Class B Shares will convert into Class A
 Shares of such Fund based on the date of the initial purchase and the CDSC
 schedule of that purchase.
 
 If you acquire Class B Shares through reinvestment of distributions, your
 Class B Shares will convert into Class A Shares based on the date of the
 initial purchase of the shares on which the distribution was paid.
 
 The conversion of Class B Shares to Class A Shares will not occur at any
 time the Funds are advised that such conversions may constitute taxable
 events for federal tax purposes, which the Funds believe is unlikely. If
 conversions do not occur as a
 
                                                                              53

 result of possible taxability, Class B Shares would continue to be subject
 to higher expenses than Class A Shares for an indeterminate period.
 
 A COMMON QUESTION ABOUT THE PURCHASE OF CLASS C SHARES
 
 
 What Is The Offering Price Of Class C Shares?
 YOU MAY PURCHASE CLASS C SHARES OF THE FUNDS AT THE NEXT DETERMINED NAV
 WITHOUT PAYING AN INITIAL SALES CHARGE. HOWEVER, IF YOU REDEEM CLASS C
 SHARES WITHIN 12 MONTHS OF PURCHASE, A CDSC OF 1% WILL BE DEDUCTED FROM THE
 REDEMPTION PROCEEDS; PROVIDED THAT IN CONNECTION WITH PURCHASES BY PENSION
 AND PROFIT SHARING PLANS, PENSION FUNDS AND OTHER COMPANY-SPONSORED BENEFIT
 PLANS, WHERE ALL OF THE CLASS C SHARES ARE REDEEMED WITHIN 12 MONTHS OF PUR-
 CHASE, A CDSC OF 1% MAY BE IMPOSED UPON THE PLAN SPONSOR OR THIRD PARTY
 ADMINISTRATOR.
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class C Shares, including the payment of compensation to Authorized Dealers.
 An amount equal to 1% of the amount invested is paid by the Distributor to
 Authorized Dealers.
 
 COMMON QUESTIONS APPLICABLE TO THE PURCHASE OF CLASS A, B
 AND C SHARES
 
 
 What Else Do I Need To Know About The CDSC On Class A, B Or C Shares?
 .The CDSC is based on the lesser of the NAV of the shares at the time of
  redemption or the original offering price (which is the original NAV).
  .No CDSC is charged on shares acquired from reinvested dividends or capi-
   tal gains distributions.
  .No CDSC is charged on the per share appreciation of your account over the
   initial purchase price.
  .When counting the number of months since a purchase of Class B or Class C
   Shares was made, all payments made during a month will be combined and
   considered to have been made on the first day of that month.
 .To keep your CDSC as low as possible, each time you place a request to sell
  shares, the Funds will first sell any shares in your account that do not
  carry a CDSC and then the shares in your account that have been held the
  longest.

 In What Situations May The CDSC On Class A, B Or C Shares Be Waived Or
 Reduced?
 The CDSC on Class A, Class B and Class C Shares that are subject to a CDSC
 may be waived or reduced if the redemption relates to:
 .Retirement distributions or loans to participants or beneficiaries from
  pension and profit sharing plans, pension funds and other company-sponsored
  benefit plans (each a "Retirement Plan");
 .The death or disability (as defined in Section 72(m)(7) of the Internal
  Revenue Code of 1986, as amended (the "Code")) of a participant or benefi-
  ciary in a Retirement Plan;
 .Hardship withdrawals by a participant or beneficiary in a Retirement Plan;
 .Satisfying the minimum distribution requirements of the Code;
 .Establishing "substantially equal periodic payments" as described under
  Section 72(t)(2) of the Code;
 .The separation from service by a participant or beneficiary in a Retirement
  Plan;
 .The death or disability (as defined in Section 72(m)(7) of the Code) of a
  shareholder if the redemption is made within one year of the event;
 .Excess contributions distributed from a Retirement Plan;
 .Distributions from a qualified Retirement Plan invested in the Goldman
  Sachs Funds which are being rolled over to a Goldman Sachs IRA; or
 .Redemption proceeds which are to be reinvested in accounts or non-regis-
  tered products over which GSAM or its advisory affiliates have investment
  discretion.
 
 In addition, Class A, B and C Shares subject to a systematic withdrawal plan
 may be redeemed without a CDSC. The Funds reserve the right to limit such
 redemptions, on an annual basis, to 12% each of the value of your Class B
 and C Shares and 10% of the value of your Class A Shares.
 
 How Do I Decide Whether To Buy Class A, B Or C Shares?
 THE DECISION AS TO WHICH CLASS TO PURCHASE DEPENDS ON THE AMOUNT YOU INVEST,
 THE INTENDED LENGTH OF THE INVESTMENT AND YOUR PERSONAL SITUATION.
 
 .CLASS A SHARES. If you are making an investment of $50,000 or more that
  qualifies for a reduced sales charge, you should consider purchasing Class
  A Shares.
 .CLASS B SHARES. If you plan to hold your investment for at least six years
  and would prefer not to pay an initial sales charge, you might consider
  purchasing Class B Shares. By not paying a front-end sales charge, your
  entire investment in Class B Shares is available to work for you from the
  time you make your initial investment. However, the distribution and serv-
  ice fee paid by Class B
 
                                                                              55
<PAGE>
 
  Shares will cause your Class B Shares (until conversion to Class A Shares)
  to have a higher expense ratio, and thus, lower performance and lower divi-
  dend payments (to the extent dividends are paid) than Class A Shares.
  A maximum purchase limitation of $250,000 in the aggregate normally
  applies to Class B Shares.
 .CLASS C SHARES. If you are unsure of the length of your investment or plan
  to hold your investment for less than six years and would prefer not to pay
  an initial sales charge, you may prefer Class C Shares. By not paying a
  front-end sales charge, your entire investment in Class C Shares is avail-
  able to work for you from the time you make your initial investment. Howev-
  er, the distribution and service fee paid by Class C Shares will cause your
  Class C Shares to have a higher expense ratio, and thus lower performance
  and lower dividend payments (to the extent dividends are paid) than Class A
  Shares (or Class B Shares after conversion to Class A Shares).
  Although Class C Shares are subject to a CDSC for only 12 months, Class C
  Shares do not have the conversion feature applicable to Class B Shares and
  your investment will therefore pay higher distribution fees indefinitely.
  A maximum purchase limitation of $1,000,000 in the aggregate normally
  applies to purchases of Class C Shares.
 
 NOTE: AUTHORIZED DEALERS MAY RECEIVE DIFFERENT COMPENSATION FOR SELLING
 CLASS A, CLASS B OR CLASS C SHARES.
 
  In addition to Class A, Class B and Class C Shares, each Fund also offers
  other classes of shares to investors. These other share classes are sub-
  ject to different fees and expenses (which affect performance), have dif-
  ferent minimum investment requirements and are entitled to different serv-
  ices. Information regarding these other share classes may be obtained from
  your sales representative or from Goldman Sachs by calling the number on
  the back cover of this Prospectus.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Class A, Class B And Class C Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. EACH FUND WILL REDEEM ITS SHARES UPON REQUEST ON
 ANY BUSINESS DAY AT THE NAV NEXT DETERMINED AFTER RECEIPT OF SUCH REQUEST IN
 PROPER FORM, SUBJECT TO ANY APPLICABLE CDSC. You may request that redemption
 proceeds be sent to you by check or by wire (if the wire instructions are on
 record). Redemptions may be requested in writing or by telephone.

                   .You may redeem up to $50,000 of your shares
                    within any 7 calendar day period
                   .Proceeds which are sent directly to a Goldman
                    Sachs brokerage account are not subject to the
                    $50,000 limit
 -------------------------------------------------------------------------
</TABLE>
 When Do I Need A Signature Guarantee To Redeem Shares?
 A signature guarantee is required if:
 .You are requesting in writing to redeem shares in an amount over $50,000;
 .You would like the redemption proceeds sent to an address that is not your
  address of record; or
 .You would like to change the bank designated on your Account Application.
 
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federal savings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.
 Additional documentation may be required for executors, trustees or corpora-
 tions or when deemed appropriate by the Transfer Agent.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 The Trust may accept telephone redemption instructions from any person iden-
 tifying himself or
 
                                                                              57
<PAGE>
 
 herself as the owner of an account or the owner's registered representative
 where the owner has not declined in writing to use this service. Thus, you
 risk possible losses if a telephone redemption is not authorized by you.
 
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs and NFDS each employ reasonable proce-
 dures specified by the Trust to confirm that such instructions are genuine.
 If reasonable procedures are not employed, the Trust may be liable for any
 loss due to unauthorized or fraudulent transactions. The following general
 policies are currently in effect:
 .All telephone requests are recorded.
 .Proceeds of telephone redemption requests will be sent only to your address
  of record or authorized bank account designated in the Account Application
  (unless you provide written instructions and a signature guarantee, indi-
  cating another address or account) and exchanges of shares normally will be
  made only to an identically registered account.
 .Telephone redemptions will not be accepted during the 30-day period follow-
  ing any change in your address of record.
 .The telephone redemption option does not apply to shares held in a "street
  name" account. "Street name" accounts are accounts maintained and serviced
  by your Authorized Dealer. If your account is held in "street name," you
  should contact your registered representative of record, who may make tele-
  phone redemptions on your behalf.
 .The telephone redemption option may be modified or terminated at any time.
 
 NOTE: IT MAY BE DIFFICULT TO MAKE TELEPHONE REDEMPTIONS IN TIMES OF DRASTIC
 ECONOMIC OR MARKET CONDITIONS.
 
 How Are Redemption Proceeds Paid?
 BY WIRE: You may arrange for your redemption proceeds to be wired as federal
 funds to the bank account designated in your Account Application. The fol-
 lowing general policies govern wiring redemption proceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If you are selling shares you recently paid for by
  check, the Fund will pay you when your check has cleared, which may take up
  to 15 days. If the Federal Reserve Bank is closed on the day that the
  redemption proceeds would ordinarily be wired, wiring the redemption pro-
  ceeds may be delayed one additional business day.
 .A transaction fee of $7.50 may be charged for payments of redemption pro-
  ceeds by wire. Your bank may also charge wiring fees. You should contact
  your bank directly to learn whether it charges such fees.

 .To change the bank designated on your Account Application, you must send
  written instructions (with your signature guaranteed) to the Transfer
  Agent.
 .Neither the Trust, Goldman Sachs nor any Authorized Dealer assumes any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
 BY CHECK: You may elect to receive your redemption proceeds by check.
 Redemption proceeds paid by check will normally be mailed to the address of
 record within three business days of a properly executed redemption request.
 If you are selling shares you recently paid for by check, the Fund will pay
 you when your check has cleared, which may take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 
 The Trust reserves the right to:
 .Redeem your shares if your account balance is less than $50 as a result of
  a redemption. The Funds will not redeem your shares on this basis if the
  value of your account falls below the minimum account balance solely as a
  result of market conditions. The Funds will give you 60 days' prior written
  notice to allow you to purchase sufficient additional shares of the Fund in
  order to avoid such redemption.
 .Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Reinvest Redemption Proceeds In The Same Or Another Goldman Sachs
 Fund?
 You may redeem shares of a Fund and reinvest a portion or all of the redemp-
 tion proceeds (plus any additional amounts needed to round off purchases to
 the nearest full share) at NAV. To be eligible for this privilege, you must
 hold the shares you want to redeem for at least 30 days and you must rein-
 vest the share proceeds within 90 days after you redeem. You may reinvest as
 follows:
  .Class A or B Shares--Class A Shares of the same Fund or any other Goldman
   Sachs Fund
  .Class C Shares--Class C Shares of the same Fund or any other Goldman
   Sachs Fund
 
                                                                              59
<PAGE>
 
 .You should obtain and read the applicable prospectuses before investing in
  any other Funds.
 .If you pay a CDSC upon redemption of Class A or Class C Shares and then
  reinvest in Class A or Class C Shares as described above, your account will
  be credited with the amount of the CDSC you paid. The reinvested shares
  will, however, continue to be subject to a CDSC. The holding period of the
  shares acquired through reinvestment will include the holding period of the
  redeemed shares for purposes of computing the CDSC payable upon a subse-
  quent redemption. For Class B Shares, you may reinvest the redemption pro-
  ceeds in Class A Shares at NAV but the amount of the CDSC paid upon redemp-
  tion of the Class B Shares will not be credited to your account.
 .The reinvestment privilege may be exercised at any time in connection with
  transactions in which the proceeds are reinvested at NAV in a tax-sheltered
  retirement plan. In other cases, the reinvestment privilege may be exer-
  cised once per year upon receipt of a written request.
 .You may be subject to tax as a result of a redemption. You should consult
  your tax adviser concerning the tax consequences of a redemption and rein-
  vestment.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange shares of a Fund at NAV without the imposition of an ini-
 tial sales charge or CDSC at the time of exchange for shares of the same
 class or an equivalent class of any other Goldman Sachs Fund. The exchange
 privilege may be materially modified or withdrawn at any time upon 60 days'
 written notice to you.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .Six free exchanges are allowed in each 12 month period.
 .A $12.50 fee may be charged for each subsequent exchange.
 .There is no charge for exchanges made pursuant to the Automatic Exchange
  Program.
 .The exchanged shares may later be exchanged for shares of the same class
  (or an equivalent class) of the original Fund at the next determined NAV
  without the imposition of an initial sales charge or CDSC if the amount in
  the Fund resulting from such exchanges is less than the largest amount on
  which you have previously paid the applicable sales charge.
 .When you exchange shares subject to a CDSC, no CDSC will be charged at that
  time. The exchanged shares will be subject to the CDSC of the shares origi-
  nally held. For purposes of determining the amount of the applicable CDSC,
  the length of time you have owned the shares will be measured from the date
  you acquired the original shares subject to a CDSC and will not be affected
  by a subsequent exchange.
 .Eligible investors may exchange certain classes of shares for another class
  of shares of the same Fund. For further information, call Goldman Sachs
  Funds at 1-800-526-7384.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs and NFDS may use reasonable procedures described under "What
  Do I Need to Know About Telephone Redemption Requests?" in an effort to
  prevent unauthorized or fraudulent telephone exchange requests.
 .Telephone exchanges normally will be made only to an identically registered
  account. Shares may be exchanged among accounts with different names,
  addresses and social security or other taxpayer identification numbers only
  if the exchange instructions are in writing and accompanied by a signature
  guarantee.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
                                                                              61

 SHAREHOLDER SERVICES
 
 
 Can I Arrange To Have Automatic Investments Made On A Regular Basis?
 You may be able to make systematic cash investments through your bank via
 ACH transfer or your checking account via bank draft each month. Forms for
 this option are available from Goldman Sachs, your Authorized Dealer or you
 may check the appropriate box on the Account Application.
 
 Can My Dividends And Distributions From A Fund Be Invested In Other Funds?
 You may elect to cross-reinvest dividends and capital gain distributions
 paid by a Fund in shares of the same class or an equivalent class of any
 other Goldman Sachs Fund.
 .Shares will be purchased at NAV.
 .No initial sales charge or CDSC will be imposed.
 .You may elect cross-reinvestment into an identically registered account or
  an account registered in a different name or with a different address,
  social security number or taxpayer identification number provided that the
  account has been properly established, appropriate signature guarantees
  obtained and the minimum initial investment has been satisfied.
 
 Can I Arrange To Have Automatic Exchanges Made On A Regular Basis?
 You may elect to exchange automatically a specified dollar amount of shares
 of a Fund for shares of the same class or an equivalent class of any other
 Goldman Sachs Fund.
 .Shares will be purchased at NAV.
 .No initial sales charge is imposed.
 .Shares subject to a CDSC acquired under this program may be subject to a
  CDSC at the time of redemption from the Fund into which the exchange is
  made depending upon the date and value of your original purchase.
 .Automatic exchanges are made monthly on the 15th day of each month or the
  first business day thereafter.
 .Minimum dollar amount: $50 per month.
 
 What Else Should I Know About Cross-Reinvestments And Automatic Exchanges?
 Cross-reinvestments and automatic exchanges are subject to the following
 conditions:
 .You must hold $5,000 or more in the Fund which is paying the dividend or
  from which the exchange is being made.

 .You must invest an amount in the Fund into which cross-reinvestments or
  automatic exchanges are being made that is equal to that Fund's minimum
  initial investment or continue to cross-reinvest or to make automatic
  exchanges until such minimum initial investment is met.
 .You should obtain and read the prospectus of the Fund into which dividends
  are invested or automatic exchanges are made.
 
 Can I Have Automatic Withdrawals Made On A Regular Basis?
 You may draw on your account systematically via check or ACH transfer in any
 amount of $50 or more.
 .It is normally undesirable to maintain a systematic withdrawal plan at the
  same time that you are purchasing additional Class A, Class B or Class C
  Shares because of the sales charge imposed on your purchases of Class A
  Shares or the imposition of a CDSC on your redemptions of Class A, Class B
  or Class C Shares.
 .You must have a minimum balance of $5,000 in a Fund.
 .Checks are mailed on or about the 25th day of each month.
 .Each systematic withdrawal is a redemption and therefore a taxable transac-
  tion.
 .The CDSC applicable to Class A, Class B or Class C Shares redeemed under
  the systematic withdrawal plan may be waived.
 
 What Types of Reports Will I Be Sent Regarding My Investment?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-526-7384. You will also be provided with a
 printed confirmation for each transaction in your account and an individual
 quarterly account statement. A year-to-date statement for your account will
 be provided upon request made to Goldman Sachs. If your account is held in
 "street name" you may receive your statement and confirmations on a differ-
 ent schedule. The Funds do not generally provide sub-accounting services.
 
 What Should I Know When I Purchase Shares Through An Authorized Dealer?
 Authorized Dealers and other financial intermediaries may provide varying
 arrangements for their clients to purchase and redeem Fund shares. They may
 charge additional fees not described in this Prospectus to their customers
 for such services.
 
 If shares of a Fund are held in a "street name" account with an Authorized
 Dealer, all recordkeeping, transaction processing and payments of distribu-
 tions relating to your account will be performed by the Authorized Dealer,
 and not by the Fund and its Transfer Agent. Since the Funds will have no
 record of your
 
                                                                              63
<PAGE>
 
 transactions, you should contact the Authorized Dealer to purchase, redeem
 or exchange shares, to make changes in or give instructions concerning the
 account or to obtain information about your account. The transfer of shares
 in a "street name" account to an account with another dealer or to an
 account directly with the Fund involves special procedures and will require
 you to obtain historical purchase information about the shares in the
 account from the Authorized Dealer.
 
 Authorized Dealers and other financial intermediaries may be authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and if approved by the Trust, to
 designate other intermediaries to accept such orders. In these cases:
 .A Fund will be deemed to have received an order that is in proper form when
  the order is accepted by an Authorized Dealer or intermediary on a business
  day, and the order will be priced at the Fund's NAV per share (adjusted for
  any applicable sales charge) next determined after such acceptance.
 .Authorized Dealers and intermediaries are responsible for transmitting
  accepted orders to the Funds within the time period agreed upon by them.
 
 You should contact your Authorized Dealer or intermediary to learn whether
 it is authorized to accept orders for the Trust.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Authorized Dealers and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Autho-
 rized Dealers depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 DISTRIBUTION SERVICES AND FEES
 
 
 What Are The Different Distribution And Service Fees Paid By Class A, B and
 C Shares?
 The Trust has adopted distribution and service plans (each a "Plan") under
 which Class A, Class B and Class C Shares bear distribution and service fees
 paid to Authorized Dealers and Goldman Sachs. If the fees received by
 Goldman Sachs pursuant to the Plans exceed its expenses, Goldman Sachs may
 realize a profit from
 
64
<PAGE>
 
                                                               SHAREHOLDER GUIDE
 
 their arrangements. Goldman Sachs pays the distribution and service fees on
 a quarterly basis.
 
 Under the Plans, Goldman Sachs is entitled to a monthly fee from each Fund
 for distribution services equal, on an annual basis, to 0.25%, 0.75% and
 0.75%, respectively, of a Fund's average daily net assets attributed to
 Class A, Class B and Class C Shares. Because these fees are paid out of the
 Fund's assets on an ongoing basis, over time, these fees will increase the
 cost of your investment and may cost you more than paying other types of
 such charges.
 
 The distribution fees are subject to the requirements of Rule 12b-1 under
 the Act, and may be used (among other things) for:
 .Compensation paid to and expenses incurred by Authorized Dealers, Goldman
  Sachs and their respective officers, employees and sales representatives;
 .Commissions paid to Authorized Dealers;
 .Allocable overhead;
 .Telephone and travel expenses;
 .Interest and other costs associated with the financing of such compensation
  and expenses;
 .Printing of prospectuses for prospective shareholders;
 .Preparation and distribution of sales literature or advertising of any
  type; and
 .All other expenses incurred in connection with activities primarily
  intended to result in the sale of Class A, Class B and Class C Shares.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.75% distribution fee as an ongoing commission to Authorized Dealers
 after the shares have been held for one year.
 
 PERSONAL ACCOUNT MAINTENANCE SERVICES AND FEES
 
 
 Under the Plans, Goldman Sachs is also entitled to receive a separate fee
 equal on an annual basis to 0.25% of each Fund's average daily net assets
 attributed to Class A, Class B or Class C Shares. This fee is for personal
 and account maintenance services, and may be used to make payments to
 Goldman Sachs, Authorized Dealers and their officers, sales representatives
 and employees for responding to inquiries of, and furnishing assistance to,
 shareholders regarding ownership of their shares or their accounts or simi-
 lar services not otherwise provided on behalf of the Funds. If the fees
 received by Goldman Sachs pursuant to the Plans exceed its expenses, Goldman
 Sachs may realize a profit from this arrangement.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.25% ongoing service fee to Authorized Dealers after the shares have
 been held for one year.
 
                                                                              65

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Fund distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Fund's net investment income, certain net realized
 foreign exchange gains and net short-term capital gains. They are taxable as
 long-term capital gains to the extent they are attributable to the Fund's
 excess of net long-term capital gains over net short-term capital losses.
 The tax status of any distribution is the same regardless of how long you
 have been in the Fund and whether you reinvest in additional shares or take
 the distribution as cash. Certain distributions paid by a Fund in January of
 a given year may be taxable to shareholders as if received the prior Decem-
 ber 31. The tax status and amounts of the distributions for each calendar
 year will be detailed in your annual tax statement from the Fund.
 
 A Fund's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Fund receives from U.S. domestic
 corporations may be eligible, in the hands of the corporate shareholders,
 for the corporate dividends-received deduction, subject to certain holding
 period requirements and debt financing limitations.
 
 Each Fund may be subject to foreign withholding or other foreign taxes on
 income or gain from certain foreign securities. In general, the Funds may
 deduct these taxes in computing their taxable income.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In its efforts to adhere to these requirements, the
 Funds may have to limit their investment activity in some types of instru-
 ments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements for the periods that you hold shares.) Any loss rec-
 ognized on shares held for six

                                                                        TAXATION
 
 months or less will be treated as a long-term capital loss to the extent of
 any capital gain dividends that were received with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from a Fund or on the value of the shares
 held by you. More tax information is provided in the Additional Statement.
 You should also consult your own tax adviser for information regarding all
 tax consequences applicable to your investments in the Funds.
 
                                                                              67

Appendix A
Additional Information on Portfolio
Risks, Securities and Techniques
 
 A. General Portfolio Risks
 
 The Funds will be subject to the risks associated with equity securities.
 "Equity securities" include common stocks, preferred stocks, interests in
 real estate investment trusts, convertible debt obligations, convertible
 preferred stocks, equity interests in trusts, partnerships, joint ventures,
 limited liability companies and similar enterprises, warrants and stock pur-
 chase rights. In general, stock values fluctuate in response to the activi-
 ties of individual companies and in response to general market and economic
 conditions. Accordingly, the value of the stocks that a Fund holds may
 decline over short or extended periods. The stock markets tend to be cycli-
 cal, with periods when stock prices generally rise and periods when prices
 generally decline. The volatility of equity securities means that the value
 of your investment in the Funds may increase or decrease. As of the date of
 this Prospectus, certain stock markets were trading at or close to record
 high levels and there can be no guarantee that such levels will continue.
 
 To the extent that a Fund invests in fixed-income securities, that Fund will
 also be subject to the risks associated with its fixed-income securities.
 These risks include interest rate risk, credit risk and call/extension risk.
 In general, interest rate risk involves the risk that when interest rates
 decline, the market value of fixed-income securities tends to increase. Con-
 versely, when interest rates increase, the market value of fixed-income
 securities tends to decline. Credit risk involves the risk that an issuer
 could default on its obligations, and a Fund will not recover its invest-
 ment. Call risk and extension risk are normally present in mortgage-backed
 securities and asset-backed securities. For example, homeowners have the
 option to prepay their mortgages. Therefore, the duration of a security
 backed by home mortgages can either shorten (call risk) or lengthen (exten-
 sion risk). In general, if interest rates on new mortgage loans fall suffi-
 ciently below the interest rates on existing outstanding mortgage loans, the
 rate of prepayment would be expected to increase. Conversely, if mortgage
 loan interest rates rise above the interest rates on existing outstanding
 mortgage loans, the rate of prepayment would be expected to decrease. In
 either case, a change in the prepayment rate can result in losses to invest-
 ors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by
 
68
<PAGE>
 
                                                                      APPENDIX A
 
 dividing the lesser of the dollar amount of sales or purchases of portfolio
 securities by the average monthly value of a Fund's portfolio securities,
 excluding securities having a maturity at the date of purchase of one year
 or less. See "Financial Highlights" in Appendix B for a statement of the
 Funds' historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all investment objectives and policies not specifically designated as
 fundamental are non-fundamental and may be changed without shareholder
 approval. If there is a change in a Fund's investment objective, you should
 consider whether that Fund remains an appropriate investment in light of
 your then current financial position and needs.
 
 B. Other Portfolio Risks
 
 
 RISKS OF INVESTING IN SMALL CAPITALIZATION COMPANIES AND REITS. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such securities. Small capitalization companies
 and REITs may be thinly traded and may have to be sold at a discount from
 current market prices or in small lots over an extended period of time. In
 addition, these securities are subject to the risk that during certain peri-
 ods the liquidity of particular issuers or industries, or all securities in
 these investment categories, will shrink or disappear suddenly and without
 warning as a result of adverse economic or market conditions, or adverse
 investor perceptions whether or not accurate. Because of the lack of suffi-
 cient market liquidity, a Fund may incur losses because it will be required
 to effect sales at a disadvantageous time and only then at a substantial
 drop in price. Small capitalization companies and REITs include "unseasoned"
 issuers that do not have an established financial history; often have lim-
 ited product lines, markets or financial resources; may depend on or use a
 few key personnel for management; and may be susceptible to losses and risks
 of bankruptcy. Transaction costs for these investments are often higher than
 those of larger capitalization companies. Investments in small capitaliza-
 tion companies and REITs may be more difficult to price precisely than other
 types of securities because of their characteristics and lower trading vol-
 umes.
 
 
                                                                              69
<PAGE>
 
 
 RISKS OF FOREIGN INVESTMENTS. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts after January 1, 1999 that refer to existing currencies
 rather than the euro; the establishment and maintenance of exchange rates
 for currencies being converted into the euro; the fluctuation of the euro
 relative to non-euro currencies during the transition period from January 1,
 1999 to December 31, 2001 and beyond; whether the interest rate, tax and
 labor regimes of European countries participating in the euro will converge
 over time; and whether the conversion of the currencies of other countries
 that now are or may in the future become members of the European Union
 ("EU"), may have an impact on the euro. These or other factors, including
 political and economic risks, could cause market disruptions, and could
 adversely affect the value of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Efforts in foreign countries to remediate potential Year

                                                                      APPENDIX A
 
 2000 problems are not as extensive as those in the United States. As a
 result, the operations of foreign markets, foreign issuers and foreign gov-
 ernments may be disrupted by the Year 2000 Problem, and the investment port-
 folio of a Fund may be adversely affected. Furthermore, with respect to cer-
 tain foreign countries, there is a possibility of nationalization,
 expropriation or confiscatory taxation, imposition of withholding or other
 taxes on dividend or interest payments (or, in some cases, capital gains),
 limitations on the removal of funds or other assets of the Funds, and polit-
 ical or social instability or diplomatic developments which could affect
 investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such debt, and a Fund may have limited recourse to compel
 payment in the event of a default. Periods of economic uncertainty may
 result in the volatility of market prices of sovereign debt, and in turn a
 Fund's NAV, to a greater extent than the volatility inherent in debt obliga-
 tions of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Funds may also invest in European Depository
 Receipts ("EDRs") or other similar instruments representing securities of
 foreign issuers. ADRs represent the right to receive securities of foreign
 issuers deposited in a domestic bank or a correspondent bank. Prices of ADRs
 are quoted in U.S. dollars, and ADRs are traded in the United States. EDRs
 and GDRs are receipts evidencing an arrangement with a non-U.S. bank. EDRs
 and GDRs are not necessarily quoted in the same currency as the underlying
 security.
 
 RISKS OF EMERGING COUNTRIES. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are gener-
 
                                                                              71
<PAGE>
 
 
 ally located in the Asia-Pacific region, Eastern Europe, Latin and South
 America and Africa. A Fund's purchase and sale of portfolio securities in
 certain emerging countries may be constrained by limitations as to daily
 changes in the prices of listed securities, periodic trading or settlement
 volume and/or limitations on aggregate holdings of foreign investors. Such
 limitations may be computed based on the aggregate trading volume by or
 holdings of a Fund, the Investment Adviser, its affiliates and their respec-
 tive clients and other service providers. A Fund may not be able to sell
 securities in circumstances where price, trading or settlement volume limi-
 tations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, it is anticipated that
 a Fund may invest in such countries through other investment funds in such
 countries.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and
 
72
<PAGE>
 
                                                                      APPENDIX A
 
 ethnic, religious and racial disaffection, among other factors, have also
 led to social unrest, violence and/or labor unrest in some emerging coun-
 tries. Unanticipated political or social developments may result in sudden
 and significant investment losses. Investing in emerging countries involves
 greater risk of loss due to expropriation, nationalization, confiscation of
 assets and property or the imposition of restrictions on foreign investments
 and on repatriation of capital invested.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Fund in emerging countries may not be as sound as the
 creditworthiness of firms used in more developed countries. As a result, the
 Fund may be subject to a greater risk of loss if a securities firm defaults
 in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than investments in countries with more developed securities mar-
 kets (such as the United States, Japan and most Western European countries).
 A Fund's investments in emerging countries are subject to the risk that the
 liquidity of a particular investment, or investments generally, in such
 countries will shrink or disappear suddenly and without warning as a result
 of adverse economic, market or political conditions or adverse investor per-
 ceptions, whether or not accurate. Because of the lack of sufficient market
 liquidity, a Fund may incur losses because it will be required to effect
 sales at a disadvantageous time and only then at a substantial drop in
 price. Investments in emerging countries may be more difficult to price pre-
 cisely because of the characteristics discussed above and lower trading vol-
 umes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.
 
                                                                              73
<PAGE>
 
 
 
 RISKS OF DERIVATIVE INVESTMENTS. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities and currency transactions involve additional risk of
 loss. Loss can result from a lack of correlation between changes in the
 value of derivative instruments and the portfolio assets (if any) being
 hedged, the potential illiquidity of the markets for derivative instruments,
 or the risks arising from margin requirements and related leverage factors
 associated with such transactions. The use of these management techniques
 also involves the risk of loss if the Investment Adviser is incorrect in its
 expectation of fluctuations in securities prices, interest rates or currency
 prices. Each Fund may also invest in derivative investments for non-hedging
 purposes (that is, to seek to increase total return). Investing for non-
 hedging purposes is considered a speculative practice and presents even
 greater risk of loss.
 
 RISKS OF ILLIQUID SECURITIES. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of
  more than seven days
 .Certain over-the-counter options
 .Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that such
  restricted security is eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 CREDIT RISKS. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Further informa-
 tion is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse

                                                                      APPENDIX A
 
 economic conditions or changing circumstances may weaken their issuers'
 capacity to pay interest and repay principal. A security will be deemed to
 have met a rating requirement if it receives the minimum required rating
 from at least one such rating organization even though it has been rated
 below the minimum rating by one or more other rating organizations, or if
 unrated by such rating organizations, determined by the Investment Adviser
 to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 TEMPORARY INVESTMENT RISKS. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 .U.S. government securities
 .Commercial paper rated at least A-2 by Standard & Poor's or P-2 by Moody's
 .Certificates of deposit
 .Bankers' acceptances
 .Repurchase agreements
 .Non-convertible preferred stocks and non-convertible corporate bonds with a
  remaining maturity of less than one year
 
 When a Fund's assets are invested in such instruments, the Fund may not be
 achieving its investment objective.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 CONVERTIBLE SECURITIES. Each Fund may invest in convertible securities. Con-
 vertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which a Fund invests are subject to the same
 rating criteria as its other investments in
 
                                                                              75
<PAGE>
 
 
 fixed-income securities. Convertible securities have both equity and fixed-
 income risk characteristics. Like all fixed-income securities, the value of
 convertible securities is susceptible to the risk of market losses attribut-
 able to changes in interest rates. Generally, the market value of convert-
 ible securities tends to decline as interest rates increase and, conversely,
 to increase as interest rates decline. However, when the market price of the
 common stock underlying a convertible security exceeds the conversion price
 of the convertible security, the convertible security tends to reflect the
 market price of the underlying common stock. As the market price of the
 underlying common stock declines, the convertible security, like a fixed-
 income security, tends to trade increasingly on a yield basis, and thus may
 not decline in price to the same extent as the underlying common stock.
 
 FOREIGN CURRENCY TRANSACTIONS. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, certain Funds may also
 enter into such transactions to seek to increase total return, which is con-
 sidered a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in connection with investments in foreign securities when, in the
 judgment of the Investment Adviser, it would be beneficial to convert such
 currency into U.S. dollars at a later date (e.g., the Investment Adviser may
 anticipate the foreign currency to appreciate against the U.S. dollar).
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are

<PAGE>
 
                                                                      APPENDIX A
 
 not guaranteed by an exchange or clearinghouse, a default on a contract
 would deprive a Fund of unrealized profits, transaction costs or the bene-
 fits of a currency hedge or could force the Fund to cover its purchase or
 sale commitments, if any, at the current market price.
 
 STRUCTURED SECURITIES. Each Fund may invest in structured securities. Struc-
 tured securities are securities whose value is determined by reference to
 changes in the value of specific currencies, interest rates, commodities,
 indices or other financial indicators (the "Reference") or the relative
 change in two or more References. The interest rate or the principal amount
 payable upon maturity or redemption may be increased or decreased depending
 upon changes in the applicable Reference. Structured securities may be posi-
 tively or negatively indexed, so that appreciation of the Reference may pro-
 duce an increase or decrease in the interest rate or value of the security
 at maturity. In addition, changes in the interest rates or the value of the
 security at maturity may be a multiple of changes in the value of the Refer-
 ence. Consequently, structured securities may present a greater degree of
 market risk than other types of fixed-income securities and may be more vol-
 atile, less liquid and more difficult to price accurately than less complex
 securities.
 
 REITS. Each Fund may invest in REITS. REITS are pooled investment vehicles
 that invest primarily in either real estate or real estate related loans.
 The value of a REIT is affected by changes in the value of the properties
 owned by the REIT or securing mortgage loans held by the REIT. REITs are
 dependent upon the ability of the REITs' managers, and are subject to heavy
 cash flow dependency, default by borrowers and the qualification of the
 REITs under applicable regulatory requirements for favorable income tax
 treatment. REITs are also subject to risks generally associated with invest-
 ments in real estate including possible declines in the value of real
 estate, general and local economic conditions, environmental problems and
 changes in interest rates. To the extent that assets underlying a REIT are
 concentrated geographically, by property type or in certain other respects,
 these risks may be heightened. A Fund will indirectly bear its proportionate
 share of any expenses, including management fees, paid by a REIT in which it
 invests.
 
 OPTIONS ON SECURITIES, SECURITIES INDICES AND FOREIGN CURRENCIES. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which they may invest or on any securities index comprised of
 securities in which they may invest. A Fund may
 
                                                                              77
<PAGE>
 
 
 also, to the extent that it invests in foreign securities, purchase and sell
 (write) put and call options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater illiquidity and credit risks.
 
 FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 government securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their term structures, sector selec-
 tion and durations in accordance with their investment objectives and poli-
 cies. Each Fund may also enter into closing purchase and sale transactions
 with respect to such contracts and options. A Fund will engage in futures
 and related options transactions for bona fide hedging purposes as defined
 in regulations of the Commodity Futures Trading Commission or to seek to
 increase total return to the extent permitted by such regulations. A Fund
 may not purchase or sell futures contracts or purchase or sell related
 options to seek to increase total return, except for closing purchase or
 sale transactions, if immediately thereafter the sum of the amount of ini-
 tial margin deposits and premiums paid on the Fund's outstanding positions
 in futures and related options entered

<PAGE>
 
                                                                      APPENDIX A
 
 into for the purpose of seeking to increase total return would exceed 5% of
 the market value of the Fund's net assets.
 
 Futures contracts and related options present the following risks:
 .While a Fund may benefit from the use of futures and options on futures,
  unanticipated changes in interest rates, securities prices or currency
  exchange rates may result in poorer overall performance than if the Fund
  had not entered into any futures contracts or options transactions.
 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and a Fund may be exposed to additional risk
  of loss.
 .The loss incurred by a Fund in entering into futures contracts and in writ-
  ing call options on futures is potentially unlimited and may exceed the
  amount of the premium received.
 .Futures markets are highly volatile and the use of futures may increase the
  volatility of a Fund's NAV.
 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to a Fund.
 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.
 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 EQUITY SWAPS. Each Fund may invest in equity swaps. Equity swaps allow the
 parties to a swap agreement to exchange the dividend income or other compo-
 nents of return on an equity investment (for example, a group of equity
 securities or an index) for a component of return on another non-equity or
 equity investment.
 
 An equity swap may be used by a Fund to invest in a market without owning or
 taking physical custody of securities in circumstances in which direct
 investment may be restricted for legal reasons or is otherwise impractical.
 Equity swaps are derivatives and their value can be very volatile. To the
 extent that the Investment Adviser does not accurately analyze and predict
 the potential relative fluctuation of the components swapped with another
 party, a Fund may suffer a loss. The value of some components of an equity
 swap (such as the dividends on a common stock) may also be sensitive to
 changes in interest rates. Furthermore, a Fund may suffer a loss if the
 counterparty defaults.
 
 WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS. Each Fund may purchase when-
 issued securities and make contracts to purchase or sell securities for a
 fixed price at a future date beyond customary settlement time. When-issued
 securities are securities that have been authorized, but not yet issued.
 When-issued securities are purchased in order to secure what is considered
 to be an advantageous price
 
                                                                              79
<PAGE>
 
 
 and yield to the Fund at the time of entering into the transaction. A for-
 ward commitment involves the entering into a contract to purchase or sell
 securities for a fixed price at a future date beyond the customary settle-
 ment period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 REPURCHASE AGREEMENTS. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with primary dealers in U.S. government securities and member banks of the
 Federal Reserve System which furnish collateral at least equal in value or
 market price to the amount of their repurchase obligation.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's costs associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Certain
 Funds, together with other registered investment companies having advisory
 agreements with the Investment Adviser or any of its affiliates, may trans-
 fer uninvested cash balances into a single joint account, the daily aggre-
 gate balance of which will be invested in one or more repurchase agreements.
 
 LENDING OF PORTFOLIO SECURITIES. Each Fund may engage in securities lending.
 Securities lending involves the lending of securities owned by a Fund to
 financial institutions such as certain broker-dealers. The borrowers are
 required to secure their loan continuously with cash, cash equivalents, U.S.
 government securities or letters of credit in an amount at least equal to
 the market value of the securities loaned. Cash collateral may be invested
 in cash equivalents. If the Investment Adviser determines to make securities
 loans, the value of the securities loaned may not exceed 33 1/3% of the
 value of the total assets of a Fund (including the loan collateral).

                                                                      APPENDIX A
 
 
 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 SHORT SALES AGAINST-THE-BOX. Certain Funds may make short sales against-the-
 box. A short sale against-the-box means that at all times when a short posi-
 tion is open the Fund will own an equal amount of securities sold short, or
 securities convertible into or exchangeable for, without payment of any fur-
 ther consideration, an equal amount of the securities of the same issuer as
 the securities sold short.
 
 PREFERRED STOCK, WARRANTS AND RIGHTS. Each Fund may invest in preferred
 stock, warrants and rights. Preferred stocks are securities that represent
 an ownership interest providing the holder with claims on the issuer's earn-
 ings and assets before common stock owners but after bond owners. Unlike
 debt securities, the obligations of an issuer of preferred stock, including
 dividend and other payment obligations, may not typically be accelerated by
 the holders of such preferred stock on the occurrence of an event of default
 or other non-compliance by the issuer of the preferred stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.
 
 OTHER INVESTMENT COMPANIES. Each Fund may invest in securities of other
 investment companies (including SPDRs and WEBs, as defined below) subject to
 statutory limitations prescribed by the Act. These limitations include a
 prohibition on any Fund acquiring more than 3% of the voting shares of any
 other investment company, and a prohibition on investing more than 5% of a
 Fund's total assets in securities of any one investment company or more than
 10% of its total assets in securities of all investment companies. A Fund
 will indirectly bear its proportionate share of any management fees and
 other expenses paid by such other investment companies. Such other invest-
 ment companies will have investment objectives, policies and restrictions
 substantially similar to those of the acquiring Fund and will be subject to
 substantially the same risks.
 
 .STANDARD & POOR'S DEPOSITORY RECEIPTS. The Funds may, consistent with their
  investment policies, purchase Standard & Poor's Depository Receipts
  ("SPDRs"). SPDRs are securities traded on the American Stock Exchange
  ("AMEX") that represent ownership in the SPDR Trust, a trust which has been
  established to accumulate and hold a portfolio of common stocks that is
  intended to track the price performance and dividend yield of the S&P 500.
  The SPDR Trust is sponsored by a subsidiary of the AMEX. SPDRs may be used
  for several reasons, including, but not limited to, facilitating the han-
  dling of
 
                                                                              81
<PAGE>
 
 
  cash flows or trading, or reducing transaction costs. The price movement of
  SPDRs may not perfectly parallel the price action of the S&P 500.
 
 .WORLD EQUITY BENCHMARK SHARES. World Equity Benchmark Shares ("WEBS") are
  shares of an investment company that invests substantially all of its
  assets in securities included in the MSCI indices for specified countries.
  WEBS are listed on the AMEX and were initially offered to the public in
  1996. The market prices of WEBS are expected to fluctuate in accordance
  with both changes in the NAVs of their underlying indices and supply and
  demand of WEBS on the AMEX. To date, WEBS have traded at relatively modest
  discounts and premiums to their NAVs. However, WEBS have a limited operat-
  ing history and information is lacking regarding the actual performance and
  trading liquidity of WEBS for extended periods or over complete market
  cycles. In addition, there is no assurance that the requirements of the
  AMEX necessary to maintain the listing of WEBS will continue to be met or
  will remain unchanged. In the event substantial market or other disruptions
  affecting WEBS should occur in the future, the liquidity and value of a
  Fund's shares could also be substantially and adversely affected. If such
  disruptions were to occur, a Fund could be required to reconsider the use
  of WEBS as part of its investment strategy.
 
 UNSEASONED COMPANIES. Each Fund may invest in companies (including predeces-
 sors) which have operated less than three years, except that this limitation
 does not apply to debt securities which have been rated investment grade or
 better by at least one NRSRO. The securities of such companies may have lim-
 ited liquidity, which can result in their being priced higher or lower than
 might otherwise be the case. In addition, investments in unseasoned compa-
 nies are more speculative and entail greater risk than do investments in
 companies with an established operating record.
 
 CORPORATE DEBT OBLIGATIONS. Corporate debt obligations include bonds, notes,
 debentures and other obligations of corporations to pay interest and repay
 principal, and include securities issued by banks and other financial insti-
 tutions. Each Fund may invest in corporate debt obligations issued by U.S.
 and certain non-U.S. issuers which issue securities denominated in the U.S.
 dollar (including Yankee and Euro obligations). In addition to obligations
 of corporations, corporate debt obligations include securities issued by
 banks and other financial institutions and supranational entities (i.e., the
 World Bank, the International Monetary Fund, etc.).
 
 BANK OBLIGATIONS. Each Fund may invest in obligations issued or guaranteed
 by U.S. or foreign banks. Bank obligations, including without limitations,
 time deposits, bankers' acceptances and certificates of deposit, may be gen-
 eral obligations of the parent bank or may be limited to the issuing branch
 by the terms of the specific obligations or by government regulations. Banks
 are subject to extensive but

                                                                      APPENDIX A
 
 different governmental regulations which may limit both the amount and types
 of loans which may be made and interest rates which may be charged. In addi-
 tion, the profitability of the banking industry is largely dependent upon
 the availability and cost of funds for the purpose of financing lending
 operations under prevailing money market conditions. General economic condi-
 tions as well as exposure to credit losses arising from possible financial
 difficulties of borrowers play an important part in the operation of this
 industry.
 
 U.S. GOVERNMENT SECURITIES AND RELATED CUSTODIAL RECEIPTS. Each Fund may
 invest in U.S. government securities and related custodial receipts. U.S.
 government securities include U.S. Treasury obligations and obligations
 issued or guaranteed by U.S. government agencies, instrumentalities or spon-
 sored enterprises. U.S. government securities may be supported by (a) the
 full faith and credit of the U.S. Treasury (such as the Government National
 Mortgage Association ("Ginnie Mae")); (b) the right of the issuer to borrow
 from the U.S. Treasury (such as securities of the Student Loan Marketing
 Association); (c) the discretionary authority of the U.S. government to pur-
 chase certain obligations of the issuer (such as the Federal National Mort-
 gage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. government
 securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. government securities, where the interest and principal compo-
 nents of stripped U.S. government securities are traded independently.
 
 Interests in U.S. government securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S.
 government.
 
 MORTGAGE-BACKED SECURITIES. Certain Funds may invest in mortgage-backed
 securities. Mortgage-backed securities represent direct or indirect partici-
 pations in, or are collateralized by and payable from, mortgage loans
 secured by real property. Mortgage-backed securities can be backed by either
 fixed rate mortgage loans or adjustable rate mortgage loans, and may be
 issued by either a governmental or non-governmental entity. Privately issued
 mortgage-backed securities are normally structured with one or more types of
 "credit enhancement." However, these mortgage-backed securities typically do
 not have the same credit standing as U.S. government guaranteed mortgage-
 backed securities.
 
 Mortgage-backed securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an
 
                                                                              83
<PAGE>
 
 
 investor with a specified interest in the cash flow from a pool of under-
 lying mortgages or of other mortgage-backed securities. CMOs are issued in
 multiple classes. In most cases, payments of principal are applied to the
 CMO classes in the order of their respective stated maturities, so that no
 principal payments will be made on a CMO class until all other classes hav-
 ing an earlier stated maturity date are paid in full. A REMIC is a CMO that
 qualifies for special tax treatment and invests in certain mortgages princi-
 pally secured by interests in real property and other permitted investments.
 
 Mortgaged-backed securities also include stripped mortgage-backed securities
 ("SMBS"), which are derivative multiple class mortgage-backed securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other mortgage-backed securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 ASSET-BACKED SECURITIES. Certain Funds may invest in asset-backed securi-
 ties. Asset-backed securities are securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed securities are often subject to more rapid repayment than their
 stated maturity date would indicate as a result of the pass-through of pre-
 payments of principal on the underlying loans. During periods of declining
 interest rates, prepayment of loans underlying asset-backed securities can
 be expected to accelerate. Accordingly, a Fund's ability to maintain posi-
 tions in such securities will be affected by reductions in the principal
 amount of such securities resulting from prepayments, and its ability to
 reinvest the returns of principal at comparable yields is subject to gener-
 ally prevailing interest rates at that time. Asset-backed securities present
 credit risks that are not presented by mortgage-backed securities. This is
 because asset-backed securities generally do not have the benefit of a secu-
 rity interest in collateral that is comparable to mortgage assets. There is
 the possibility that, in some cases, recoveries on repossessed collateral
 may not be available to support payments on these securities. In the event
 of a default, a Fund may suffer a loss if it cannot sell collateral quickly
 and receive the amount it is owed.
 
 BORROWINGS. Each Fund can borrow money from banks and other financial insti-
 tutions in amounts not exceeding one-third of their total assets for tempo-
 rary or emergency purposes. A Fund may not make additional investments if
 borrowings exceed 5% of its total assets.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

Prior Performance of Similarly Advised
Accounts of the Investment Adviser
 
 EUROPEAN EQUITY FUND
 
 
 The following table sets forth the Investment Adviser's composite perfor-
 mance data relating to the historical performance of all discretionary pri-
 vate accounts managed by the Investment Adviser that have investment objec-
 tives, policies, and strategies substantially similar to the European Equity
 Fund. The information is provided to illustrate the past performance of the
 Investment Adviser in managing substantially similar accounts as measured
 against the FT/S&P Actuaries Europe Index (unhedged) and does not represent
 the performance of the European Equity Fund. Investors should not consider
 this performance data as a substitute for the performance of the European
 Equity Fund nor should investors consider this data as an indication of
 future performance of the European Equity Fund or of the Investment Adviser.
 The FT/S&P Actuaries Europe Index (unhedged) is unmanaged and investors can-
 not invest directly in the Index.

In accordance with the standards of the Association for Investment Management
and Research ("AIMR"), the Investment Adviser's composite performance informa-
tion was calculated on a time-weighted and asset-weighted total return basis
which includes realized and unrealized gains and losses plus income. The com-
posite performance is net of applicable investment management fees, brokerage
commissions, execution costs and custodial fees, without provision for federal
and state taxes, if any. Total return performance of the European Equity Fund
will be calculated in accordance with the regulations of the SEC. The SEC stan-
dardized average annual total return is neither time-weighted nor asset-
weighted and is determined for specified periods by computing the annualized
percentage change in the value of an initial amount that is invested in a share
class of the Fund at the maximum public offering price. Investors should be
aware that the differences in methodology between AIMR and SEC requirements
could result in different performance data for identical time periods.
 
Performance reflects the deduction of the maximum 5.5% front-end sales charge
with respect to Class A Shares and the maximum CDSC with respect to Class B
(5%) and Class C Shares (1%). All returns presented reflect the reinvestment of
dividends and other earnings. The weighted-average expenses of the private
accounts used in calculating the Investment Adviser's net composite performance
data were 0.46% annualized, which are lower than the estimated expenses of
Class A, Class B and Class C Shares of the European Equity Fund stated under
"Fund Fees and Expenses" above. The performance of the private accounts would
have been lower if they had been subject to the expenses of the European Equity
Fund. In addition, the private accounts are not subject to the same diversifi-
cation requirements, specific tax restrictions and investment limitations
imposed on the European Equity Fund by the Act and Subchapter M of the Code.
Consequently, the performance results of the Investment Adviser's composite
could have been adversely affected if the private accounts had been regulated
as investment companies under the federal securities laws.

 The Investment Adviser attempts to manage risk in these Funds through disci-
 plined portfolio construction and continual portfolio review and analysis.
 As a result, bottom-up stock selection, driven by fundamental research,
 should be a main driver of returns.

 QUANTITATIVE ("CORE") STYLE FUNDS
 
 
 Goldman Sachs' CORE Investment Philosophy:
 
 Goldman Sachs' quantitative style of funds--CORE--emphasizes the two build-
 ing blocks of active management: stock selection and portfolio construction.
 
 I. CORE Stock Selection
 The CORE Funds use the Goldman Sachs proprietary multifactor model
 ("Multifactor Model"), a rigorous computerized rating system, to forecast
 returns on securities held in each Fund's portfolio. The Multifactor Model
 incorporates common variables covering measures of:
 .Value (price-to-book, price-to-earnings, cash flow to enterprise value)
 .Momentum (earnings momentum, price momentum, sustainable growth)
 .Risk (market risk, company-specific risk, earnings risk)
 
 All of the above factors are carefully evaluated within the Multifactor
 Model since each has demonstrated a significant impact on the performance of
 the securities and markets they were designed to forecast.
 
 II. CORE Portfolio Construction
 A proprietary computer optimizer calculates every security combination (at
 every possible weighting) to construct the most efficient risk/return port-
 folio given each CORE Fund benchmark. In this process, the Investment
 Adviser manages risk by limiting deviations from the benchmark.
 
 Goldman Sachs CORE Funds are fully invested, broadly diversified and offer
 consistent overall portfolio characteristics. They may serve as good founda-
 tions on which to build a portfolio.

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term growth of capital. The Fund seeks this objective
 through a broadly diversified portfolio of equity securities of large-cap
 companies that are organized outside the United States or whose securities
 are principally traded outside the United States.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, at least
 90% of its total assets in equity securities of companies that are organized
 outside the United States or whose securities are principally traded outside
 the United States.
 
 The Fund may allocate its assets among countries as determined by the
 Investment Adviser from time to time, provided the Fund's assets are
 invested in at least three foreign countries. The Fund may invest in the
 securities of issuers in countries with emerging markets or economies
 ("emerging countries").
 
 The Fund seeks broad representation of large-cap issuers across major coun-
 tries and sectors of the international economy. The Fund's investments are
 selected using both a variety of quantitative techniques and fundamental
 research in seeking to maximize the Fund's expected return, while maintain-
 ing risk, style, capitalization and industry characteristics similar to the
 EAFE Index. In addition, the Fund seeks a portfolio composed of companies
 with attractive valuations and stronger momentum characteristics than the
 EAFE Index.
 
 Other. The Fund's investments in fixed-income securities are limited to
 securities that are considered to be cash equivalents, such as corporate
 debt and bank obligations.

 INVESTMENT OBJECTIVE

 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 companies that are organized outside the United States or whose securities
 are principally traded outside the United States. The Fund intends to invest
 in companies with public stock market capitalizations that are larger than
 $1 billion at the time of investment.
 
 The Fund may allocate its assets among countries as determined by the
 Investment Adviser from time to time provided that the Fund's assets are
 invested in at least three foreign countries.
 
 The Fund expects to invest a substantial portion of its assets in the secu-
 rities of issuers located in the developed countries of Western Europe and
 in Japan. However, the Fund may also invest in the securities of issuers
 located in Australia, Canada, New Zealand and in emerging countries. Cur-
 rently, emerging countries include, among others, most Latin American, Afri-
 can, Asian and Eastern European nations.
 
 Other. The Fund may also invest up to 35% of its total assets in fixed-
 income securities, such as corporate debt and bank obligations.

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 European companies. Because of its focus, the Fund will be more susceptible
 to European economic, market, political and local risks than a fund that is
 more geographically diversified.
 
 A European issuer is a company that either:
 .Has a class of its securities whose principal securities markets is in a
  European country;
 .Is organized under the laws of, or has a principal office in, a European
  country;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in one or more of the European countries; or
 .Maintains 50% or more of its assets in one or more of the European coun-
  tries.
 
 The Fund may allocate its assets among different countries as determined by
 the Investment Adviser from time to time, provided that the Fund's assets
 are invested in at least three European countries. It is currently antici-
 pated that a majority of the Fund's assets will be invested in the equity
 securities of large cap companies located in the developed countries of
 Western Europe. However, the Fund may also invest, without limit, in mid cap
 companies and small cap companies, as well as companies located in emerging
 countries. Currently, emerging countries include among others, most Latin
 American, African, Asian, most Eastern European nations, including the
 states that formerly comprised the Soviet Union and Yugoslavia.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of non-European countries and in fixed-income securities,
 such as corporate debt and bank obligations.

 INVESTMENT OBJECTIVE

 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 Japanese companies. A Japanese issuer is a company that either:
 .Has a class of its securities whose principal securities markets is in
  Japan;
 .Is organized under the laws of, or has a principal office in Japan;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in Japan; or
 .Maintains 50% or more of its assets in Japan.
 
 The Fund's concentration in Japanese companies will expose it to the risk of
 adverse social, political and economic events which occur in Japan or affect
 the Japanese markets.
 
 Japan's economy, the second largest in the world, has grown substantially
 over the last three decades. Since 1990, however, Japan's economic growth
 has declined significantly, and is currently subject to deflationary pres-
 sures. In addition to this economic downturn, Japan is undergoing structural
 adjustments related to high wages and taxes, currency valuations and struc-
 tural rigidities. Japan has also been experiencing notable uncertainty and
 loss of public confidence in connection with the reform of its political
 process and the deregulation of its economy. These conditions present risks
 to the Japanese Equity Fund and its ability to attain its investment objec-
 tive.

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
 
 
 Japan's economy is heavily dependent upon international trade, and is espe-
 cially sensitive to trade barriers and disputes. In particular, Japan relies
 on large imports of agricultural products, raw materials and fuels. A sub-
 stantial rise in world oil or commodity prices, or a fall-off in Japan's
 manufactured exports, could be expected to adversely affect Japan's economy.
 In addition, Japan is vulnerable to earthquakes, volcanoes and other natural
 disasters. As of the date of this Prospectus, Japan's banking industry con-
 tinued to suffer from non-performing loans, declining real estate values and
 lower valuations of securities holdings.
 
 The Japanese securities markets are less regulated than the U.S. markets.
 Evidence has emerged from time to time of distortion of market prices to
 serve political or other purposes. Shareholders' rights are also not always
 equally enforced.
 
 The common stocks of many Japanese companies trade at high price-earnings
 ratios. Differences in accounting methods make it difficult to compare the
 earnings of Japanese companies with those of companies in other countries,
 especially the United States. In general, however, reported net income in
 Japan is understated relative to U.S. accounting standards and this is one
 reason price-earnings ratios of the stocks of Japanese companies have tended
 historically to be higher than those of U.S. stocks. In addition, Japanese
 companies have tended to have higher growth rates than U.S. companies, and
 Japanese interest rates have generally been lower than U.S. interest rates.
 These factors have contributed to lower discount rates and higher price-
 earnings ratios in Japan than in the United States.
 
 During the recent past the average stock market prices of Japanese compa-
 nies, as measured by major indices such as the NIKKEI 225 Average, have
 experienced a substantial decline. It is not possible to determine whether
 this general decline will continue.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of non-Japanese companies and in fixed-income securities,
 such as corporate debt and bank obligations.

 tially all, and at least 65% of its total assets in equity securities of
 companies:
 .With public stock market capitalizations of $1 billion or less at the time
  of investment; and
 .That are organized outside the United States or whose securities are prin-
  cipally traded outside the United States.
 
 The Fund may allocate its assets among countries as determined by the
 Investment Adviser from time to time provided that the Fund's assets are
 invested in at least three foreign countries. The Fund expects to invest a
 substantial portion of its assets in small cap securities of companies in
 the developed countries of Western Europe, Japan and Asia. However, the Fund
 may also invest in the securities of issuers located in Australia, Canada,
 New Zealand and in emerging countries. Currently, emerging countries
 include, among others, most Latin American, African, Asian and Eastern Euro-
 pean nations.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of larger-cap companies with public stock market capital-
 izations of more than $1 billion at the time of investment and in fixed-
 income securities, such as corporate debt and bank obligations. If the mar-
 ket capitalization of a company held by the Fund increases above $1 billion,
 the Fund may, consistent with its investment objective, continue to hold the
 security.

 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 emerging country issuers. The Investment Adviser may consider classifica-
 tions by the World Bank, the International Finance Corporation or the United
 Nations and its agencies in determining whether a country is emerging or
 developed. Currently, emerging countries include, among others, most Latin
 American, African, Asian and Eastern European nations. The Investment
 Adviser currently intends that the Fund's investment focus will be in the
 following emerging countries as well as any other emerging country to the
 extent that foreign investors are permitted by applicable law to make such
 investments:

 An emerging country issuer is any company that either:
 .Has a class of its securities whose principal securities market is in an
  emerging country;
 .Is organized under the laws of, or has a principal office in, an emerging
  country;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in one or more emerging countries; or
 .Maintains 50% or more of its assets in one or more of the emerging coun-
  tries.
 
 Under normal circumstances, the Fund maintains investments in at least six
 emerging countries, and will not invest more than 35% of its total assets in
 securities of issuers in any one emerging country. Allocation of the Fund's
 investments will depend upon the relative attractiveness of the emerging
 country markets and particular issuers. In addition, macro-economic factors
 and the portfolio managers' and Goldman Sachs economists' views of the rela-
 tive attractiveness of emerging countries and currencies are considered in
 allocating the Fund's assets among emerging countries.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 (i) fixed-income securities, such as corporate debt and bank obligations, of
 private and governmental emerging country issuers; and (ii) equity and
 fixed-income securities, such as corporate debt and bank obligations, of
 issuers in developed countries.

 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 Asian issuers.
 An Asian issuer is any company that either:
 .Has a class of its securities whose principal securities markets is in one
  or more Asian countries;
 .Is organized under the laws of, or has a principal office in, an Asian
  country;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in one or more Asian countries; or
 .Maintains 50% or more of its assets in one or more Asian countries.
 
 The Fund may allocate its assets among the Asian countries as determined
 from time to time by the Investment Adviser. For purposes of the Fund's
 investment policies, Asian countries are:
 .China               .Malaysia           .South Korea
 .Hong Kong           .Pakistan           .Sri Lanka
 .India               .Philippines        .Taiwan
 .Indonesia           .Singapore          .Thailand
 
 as well as any other country in Asia (other than Japan) to the extent that
 foreign investors are permitted by applicable law to make such investments.

Goldman Sachs Asia Growth Fund continued
 
 
 Allocation of the Fund's investments will depend upon the Investment Advis-
 er's views of the relative attractiveness of the Asian markets and particu-
 lar issuers.
 
 Concentration of the Fund's assets in one or a few of the Asian countries
 and Asian currencies will subject the Fund to greater risks than if the
 Fund's assets were not so concentrated. For example, on January 31, 1999
 (the end of the Fund's last fiscal year), more than 25% of the Fund's assets
 were invested in securities that traded in Hong Kong.
 
 Starting in mid-1997 some Pacific region countries began to experience cur-
 rency devaluations that resulted in high interest rate levels and sharp
 reductions in economic activity. This situation resulted in a significant
 drop in the securities prices of companies located in the region. Some coun-
 tries have experienced government intervention, have sought assistance from
 the International Monetary Fund and are undergoing substantial domestic
 unrest. Although some countries are taking steps to restructure their finan-
 cial sectors in a manner that may facilitate a return to long-term economic
 growth, there can be no assurance that these efforts will be successful or
 that their current problems will not persist. At the end of its last fiscal
 year, a substantial portion of the Asia Growth Fund was invested in securi-
 ties traded in the Hong Kong market. In 1997, the sovereignty of Hong Kong
 reverted from the United Kingdom to China. Although Hong Kong is, by law, to
 maintain a high degree of autonomy, there can also be no assurance that the
 general economic position of Hong Kong will not be adversely affected as a
 result of the exercise of Chinese sovereignty over Hong Kong. In particular,
 business confidence in Hong Kong can be significantly affected by political
 developments and statements by public figures in China, which can in turn
 affect the performance of the securities markets. In addition, the reversion
 of Hong Kong to China has created uncertainty as to future currency valua-
 tions relative to the U.S. dollar. Any future valuation changes could be
 adverse from the perspective of U.S. investors.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of issuers in other countries, including Japan, and in
 fixed-income securities, such as corporate debt and bank obligations.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete
investment program. There can be no assurance that a Fund will achieve its
investment objective.

All Funds:
 
 .Credit/Default Risk--The risk that an issuer of fixed-income securities held
 by a Fund (which may have low credit ratings) may default on its obligation to
 pay interest and repay principal.
 .Emerging Countries Risk--The securities markets of Asian, Latin American,
 Eastern European, African and other emerging countries are less liquid, are
 especially subject to greater price volatility, have smaller market capital-
 izations, have less government regulation and are not subject to as extensive
 and frequent accounting, financial and other reporting requirements as the
 securities markets of more developed countries. Further, investment in equity
 securities of issuers located in Russia and certain other emerging countries
 involves risk of loss resulting from problems in share registration and cus-
 tody and substantial economic and political disrup-

                                  PRINCIPAL INVESTMENT SECURITIES AND TECHNIQUES
 
 tions. These risks are not normally associated with investment in more devel-
 oped countries.
 .Interest Rate Risk--The risk that when interest rates increase, fixed-income
 securities held by a Fund will decline in value. Long-term fixed-income secu-
 rities will normally have more price volatility because of this risk than
 short-term securities.
 .Foreign Risks--The risk that when a Fund invests in foreign securities, it
 will be subject to risks not typically associated with domestic issuers. Loss
 may result because of less foreign government regulation, less public informa-
 tion and less economic, political and social stability. Loss may also result
 from the imposition of exchange controls, confiscations and other government
 restrictions. A Fund will also be subject to the risk of negative foreign cur-
 rency rate fluctuations. Foreign risks will normally be greatest when a Fund
 invests in issuers located in emerging countries.
 .Derivatives Risk--The risk that loss may result from a Fund's investments in
 options, futures, swaps, structured securities and other derivative instru-
 ments. These instruments may be leveraged so that small changes may produce
 disproportionate losses to a Fund.
 .Management Risk--The risk that a strategy used by the Investment Adviser may
 fail to produce the intended results.
 .Market Risk--The risk that the value of the securities in which a Fund invests
 may go up or down in response to the prospects of individual companies and/or
 general economic conditions. Price changes may be temporary or last for
 extended periods.
 .Liquidity Risk--The risk that a Fund will not be able to pay redemption pro-
 ceeds within the time period stated in this Prospectus, because of unusual
 market conditions, an unusually high volume of redemption requests, or other
 reasons. Funds that invest in small capitalization stocks and emerging country
 issuers will be especially subject to the risk that during certain periods the
 liquidity of particular issuers or industries, or all securities within these
 investment categories, will shrink or disappear suddenly and without warning
 as a result of adverse economic, market or political events, or adverse
 investor perceptions whether or not accurate.
 .Stock Risk--The risk that stock prices have historically risen and fallen in
 periodic cycles. As of the date of this Prospectus, U.S. stock markets and
 certain foreign stock markets were trading at or close to record high levels.
 There is no guarantee that such levels will continue.
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
                                                                              19
<PAGE>
 
 
Specific Funds:
 
 .Small Cap Stock Risk--The securities of small capitalization stocks involve
 greater risks than those associated with larger, more established companies
 and may be subject to more abrupt or erratic price movements. Securities of
 such issuers may lack sufficient market liquidity to enable a Fund to effect
 sales at an advantageous time or without a substantial drop in price.
 .Geographic Risk--The European Equity Fund invests primarily in equity securi-
 ties of European companies. The Japanese Equity Fund invests primarily in
 equity securities of Japanese equity companies. The Asia Growth Fund invests
 primarily in equity securities of Asian issuers. Concentration of the invest-
 ments of these or other Funds in issuers located in a particular country or
 region will subject the Fund, to a greater extent than if investments were
 less concentrated, to the risks of adverse securities markets, exchange rates
 and social, political, regulatory or economic events which may occur in that
 country or region.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Insti-
 tutional Shares from year to year; and (b) how the average annual returns of
 a Fund's Institutional Shares compare to those of broad-based securities
 market indices. The bar chart and table assume reinvestment of dividends and
 distributions. A Fund's past performance is not necessarily an indication of
 how the Fund will perform in the future. Performance reflects expense limi-
 tations in effect. If expense limitations were not in place, a Fund's per-
 formance would have been reduced. The European Equity, Japanese Equity and
 International Small Cap Funds did not commence operations until October 1,
 1998, May 1, 1998 and May 1, 1998. Since these Funds have less than one cal-
 endar year's performance, no performance information is provided in this
 section.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the expense limitations) with the cost of investing in other
mutual funds. The Example assumes that you invest $10,000 in Institutional
Shares of a Fund for the time periods indicated and then redeem all of your
shares at the end of those periods. The Example also assumes that your invest-
ment has a 5% return each year and that a Fund's operating expenses remain the
same. Although your actual costs may be higher or lower, based on these assump-
tions your costs would be:

Institutions that invest in Institutional Shares on behalf of their customers
may charge other fees directly to their customer accounts in connection with
their investments. You should contact your institution for information regard-
ing such charges. Such fees, if any, may affect the return customers realize
with respect to their investments.
 
Certain institutions that invest in Institutional Shares on behalf of their
customers may receive other compensation in connection with the sale and dis-
tribution of such shares or for services to their customers' accounts and/or
the Funds. For additional information regarding such compensation, see "Share-
holder Guide" in the Prospectus and "Other Information" in the Statement of

 GSAM is a separate operating division of Goldman Sachs, which registered as
 an investment adviser in 1981. GSAMI, a member of the Investment Management
 Regulatory Organization Limited since 1990 and a registered investment
 adviser since 1991, is an affiliate of Goldman Sachs. The Goldman Sachs
 Group, L.P., which controls the Investment Advisers, announced that it will
 pursue an initial public offering of the firm in the late spring or early
 summer of 1999. Simultaneously with the offering, the Goldman Sachs Group,
 L.P. will merge into The Goldman Sachs Group, Inc. As of February 28, 1999,
 GSAM and GSAMI, together with their affiliates, acted as investment adviser
 or distributor for assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser makes the investment decisions
 for the Funds and places purchase and sale orders for the Funds' portfolio
 transactions in U.S. and foreign markets. As permitted by applicable law,
 these orders may be directed to any brokers, including Goldman Sachs and its
 affiliates. While the Investment Adviser is ultimately responsible for the
 management of the Funds, it is able to draw upon the research and expertise
 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.
 
 The Investment Adviser also performs the following additional services for
 the Funds:
 .Supervises all non-advisory operations of the Funds

 The difference, if any, between the stated fees and the actual fees paid by

 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that a Fund
 could sustain losses during periods in which Goldman Sachs and its affili-
 ates and other accounts achieve significant profits on their trading for
 proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors

 known as the "Year 2000 Problem"). To the extent these systems conduct for-
 ward-looking calculations, these computer problems may occur prior to Janu-
 ary 1, 2000. Like other investment companies and financial and business
 organizations, the Funds could be adversely affected in their ability to
 process securities trades, price securities, provide shareholder account
 services and otherwise conduct normal business operations if the Investment
 Adviser or other Fund service providers do not adequately address this prob-
 lem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
                                                                              39

Dividends
 
 Each Fund pays dividends from its net investment income and distributions
 from net realized capital gains. You may choose to have dividends and dis-
 tributions paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund.
  Special restrictions may apply for certain ILA Portfolios. See the
  Additional Statement.
 
 You may indicate your election on your Account Application. Any changes may
 be submitted in writing to Goldman Sachs at any time before the record date
 for a particular dividend or distribution. If you do not indicate any
 choice, your dividends and distributions will be reinvested automatically in
 the applicable Fund.
 
 The election to reinvest dividends and distributions in additional shares
 will not affect the tax treatment of such dividends and distributions, which
 will be treated as received by you and then used to purchase the shares.
 Under certain circumstances, the Funds may make an election to treat a pro-
 portionate amount of such taxes as constituting a distribution to you, which
 would allow you either (1) to credit such proportionate amount of taxes
 against your U.S. federal income tax liability or (2) to take such amount as
 an itemized deduction.
 
 Dividends from net investment income and distributions from net capital
 gains are declared and paid annually.
 
 From time to time a portion of a Fund's dividends may constitute a return
 of capital.
 
 At the time of an investor's purchase of shares of a Fund, a portion of the
 NAV per share may be represented by undistributed income or realized or
 unrealized appreciation of the Fund's portfolio securities. Therefore, sub-
 sequent distributions on such shares from such income or realized apprecia-
 tion may be taxable to you even if the NAV of the shares is, as a result of
 the distributions, reduced below the cost of such shares and the distribu-
 tions (or portions thereof) represent a return of a portion of the purchase
 price.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Institutional
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Institutional Shares Of The Funds?
 You may purchase Institutional Shares on any business day at their net asset
 value ("NAV") next determined after receipt of an order. No sales load is
 charged. You should place an order with Goldman Sachs at 1-800-621-2550 and
 either:
 .Wire federal funds to The Northern Trust Company ("Northern"), as
  subcustodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian) on the next business day; or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Northern;
  or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 In order to make an initial investment in a Fund, you must furnish to the
 Fund or Goldman Sachs the Account Application attached to this Prospectus.
 Purchases of Institutional Shares must be settled within three business days
 of receipt of a complete purchase order.
 
 How Do I Purchase Shares Through A Financial Institution?
 Certain institutions (including banks, trust companies, brokers and invest-
 ment advisers) that provide recordkeeping, reporting and processing services
 to their customers may be authorized to accept, on behalf of Goldman Sachs
 Trust (the "Trust"), purchase, redemption and exchange orders placed by or
 on behalf of their customers, and may designate other intermediaries to
 accept such orders, if approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized institution or intermediary on a busi-
  ness day, and the order will be priced at the Fund's NAV next determined
  after such acceptance.
 .Authorized institutions and intermediaries will be responsible for trans-
  mitting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 You should contact your institution or intermediary to learn whether it is
 authorized to accept orders for the Trust.
 
                                                                              41
<PAGE>
 
 
 These institutions may receive payments from the Funds or Goldman Sachs for
 the services provided by them with respect to the Funds' Institutional
 Shares. These payments may be in addition to other payments borne by the
 Funds.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to certain institutions and other persons in
 connection with the sale, distribution and/or servicing of shares of the
 Funds and other Goldman Sachs Funds. Subject to applicable NASD regulations,
 the Investment Adviser, Distributor and/or their affiliates may also con-
 tribute to various cash and non-cash incentive arrangements to promote the
 sale of shares. This additional compensation can vary among such institu-
 tions depending upon such factors as the amounts their customers have
 invested (or may invest) in particular Goldman Sachs Funds, the particular
 program involved, or the amount of reimbursable expenses. Additional compen-
 sation based on sales may, but is currently not expected to, exceed 0.50%
 (annualized) of the amount invested.
 
 In addition to Institutional Shares, each Fund also offers other classes of
 shares to investors. These other share classes are subject to different fees
 and expenses (which affect performance), have different minimum investment
 requirements and are entitled to different services than Institutional
 Shares. Information regarding these other share classes may be obtained from
 your sales representative or from Goldman Sachs by calling the number on the
 back cover of this Prospectus.

 The minimum investment requirement may be waived for current and former
 officers, partners, directors or employees of Goldman Sachs or any of its
 affiliates or for other investors at the discretion of the Trust's officers.
 No minimum amount is required for subsequent investments.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment amounts.
 .Reject or restrict any purchase or exchange orders by a particular pur-
  chaser (or group of related purchasers). This may occur, for example, when
  a pattern of frequent purchases, sales or exchanges of Institutional Shares
  of a Fund is evident, or if purchases, sales or exchanges are, or a subse-
  quent abrupt redemption might be, of a size that would disrupt the manage-
  ment of a Fund.
 
                                                                              43
<PAGE>
 
 
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Institutional
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
 
 The Funds' investments are valued based on market quotations or, if accurate
 quotations are not readily available, the fair value of the Fund's invest-
 ments may be determined in good faith under procedures established by the
 Trustees.
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will not be priced on any day
  the New York Stock Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form.
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if
 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 In addition, the impact of events that occur after the publication of market
 quotations used by a Fund to price its securities but before the close of
 regular trading on the New York Stock Exchange will normally not be
 reflected in a Fund's next determined NAV unless the Trust, in its discre-
 tion, makes an adjustment in light of the nature and materiality of the
 event, its effect on Fund operations and other relevant factors.

 HOW TO SELL SHARES
 
 
 How Can I Sell Institutional Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Generally, each Fund will redeem its Institu-
 tional Shares upon request on any business day at their NAV next determined
 after receipt of such request in proper form. You may request that redemp-
 tion proceeds be sent to you by check or by wire (if the wire instructions
 are on record). Redemptions may be requested in writing or by telephone.

</TABLE>
 Certain institutions and intermediaries are authorized to accept redemption
 requests on behalf of the Funds as described under "How Do I Purchase Shares
 Through A Financial Institution?"
 
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
 
                                                                              45
<PAGE>
 
 
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: You may arrange for your redemption proceeds to be wired as federal
 funds to the bank account designated in your Account Application. The fol-
 lowing general policies govern wiring redemption proceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If you are selling shares you recently paid for by
  check, the Fund will pay you when your check has cleared, which may take up
  to 15 days. If the Federal Reserve Bank is closed on the day that the
  redemption proceeds would ordinarily be wired, wiring the redemption pro-
  ceeds may be delayed one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  account application to the Transfer Agent.
 .Neither the Trust, Goldman Sachs nor any other institution assumes any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
 
 By Check: You may elect in writing to receive your redemption proceeds by
 check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of a properly executed redemp-
 tion request. If you are selling shares you recently paid for by check, the
 Fund will pay you when your check has cleared, which may take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Institutions (including banks, trust companies, brokers and investment
  advisers) are responsible for the timely transmittal of redemption requests
  by their customers to the Transfer Agent. In order to facilitate the timely
  transmittal of redemption requests, these institutions may set times by
  which they must receive

  redemption requests. These institutions may also require additional docu-
  mentation from you.
 
 The Trust reserves the right to:
 .Redeem your shares if your account balance falls below $50 as a result of
  earlier redemptions. The Funds will not redeem your shares on this basis if
  the value of your account falls below the minimum account balance solely as
  a result of market conditions. The Fund will give you 60 days' prior writ-
  ten notice to allow you to purchase sufficient additional shares of the
  Fund in order to avoid such redemption.
 .Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange Institutional Shares of a Fund at NAV for Institutional
 Shares of any other Goldman Sachs Fund. The exchange privilege may be mate-
 rially modified or withdrawn at any time upon 60 days' written notice to
 you.

</TABLE>
 
 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 
                                                                              47
<PAGE>
 
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types of Reports Will I Be Sent Regarding Investments In Institutional
 Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-621-2550. You will also be provided with a
 printed confirmation for each transaction in your account and a monthly
 account statement. The Funds do not generally provide sub-accounting servic-
 es.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Fund distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Fund's net investment income, certain net realized
 foreign exchange gains and net short-term capital gains. They are taxable as
 long-term capital gains to the extent they are attributable to the Fund's
 excess of net long-term capital gains over net short-term capital losses.
 The tax status of any distribution is the same regardless of how long you
 have been in the Fund and whether you reinvest in additional shares or take
 the distribution as cash. Certain distributions paid by a Fund in January of
 a given year may be taxable to shareholders as if received the prior Decem-
 ber 31. The tax status and amounts of the distributions for each calendar
 year will be detailed in your annual tax statement from the Fund.
 
 A Fund's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Fund receives from U.S. domestic
 corporations may be eligible, in the hands of the corporate shareholders,
 for the corporate dividends-received deduction, subject to certain holding
 period requirements and debt financing limitations.
 
 Each Fund may be subject to foreign withholding or other foreign taxes on
 income or gain from certain foreign securities. In general, the Funds may
 deduct these taxes in computing their taxable income.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In its efforts to adhere to these requirements, the
 Funds may have to limit their investment activity in some types of instru-
 ments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements
 
                                                                              49
<PAGE>
 
 for the periods that you hold shares.) Any loss recognized on shares held
 for six months or less will be treated as a long-term capital loss to the
 extent of any capital gain dividends that were received with respect to the
 shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from a Fund or on the value of the shares
 held by you. More tax information is provided in the Additional Statement.
 You should also consult your own tax adviser for information regarding all
 tax consequences applicable to your investments in the Funds.

Additional Information on Portfolio Risks, Securities and Techniques
 
 A. General Portfolio Risks
 
 The Funds will be subject to the risks associated with equity securities.
 "Equity securities" include common stocks, preferred stocks, interests in
 real estate investment trusts, convertible debt obligations, convertible
 preferred stocks, equity interests in trusts, partnerships, joint ventures,
 limited liability companies and similar enterprises, warrants and stock pur-
 chase rights. In general, stock values fluctuate in response to the activi-
 ties of individual companies and in response to general market and economic
 conditions. Accordingly, the value of the stocks that a Fund holds may
 decline over short or extended periods. The stock markets tend to be cycli-
 cal, with periods when stock prices generally rise and periods when prices
 generally decline. The volatility of equity securities means that the value
 of your investment in the Funds may increase or decrease. As of the date of
 this Prospectus, certain stock markets were trading at or close to record
 high levels and there can be no guarantee that such levels will continue.
 
 To the extent that a Fund invests in fixed-income securities, that Fund will
 also be subject to the risks associated with its fixed-income securities.
 These risks include interest rate risk, credit risk and call/extension risk.
 In general, interest rate risk involves the risk that when interest rates
 decline, the market value of fixed-income securities tends to increase. Con-
 versely, when interest rates increase, the market value of fixed-income
 securities tends to decline. Credit risk involves the risk that an issuer
 could default on its obligations, and a Fund will not recover its invest-
 ment. Call risk and extension risk are normally present in mortgage-backed
 securities and asset-backed securities. For example, homeowners have the
 option to prepay their mortgages. Therefore, the duration of a security
 backed by home mortgages can either shorten (call risk) or lengthen (exten-
 sion risk). In general, if interest rates on new mortgage loans fall suffi-
 ciently below the interest rates on existing outstanding mortgage loans, the
 rate of prepayment would be expected to increase. Conversely, if mortgage
 loan interest rates rise above the interest rates on existing outstanding
 mortgage loans, the rate of prepayment would be expected to decrease. In
 either case, a change in the prepayment rate can result in losses to invest-
 ors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by
 
                                                                              51

 dividing the lesser of the dollar amount of sales or purchases of portfolio
 securities by the average monthly value of a Fund's portfolio securities,
 excluding securities having a maturity at the date of purchase of one year
 or less. See "Financial Highlights" in Appendix B for a statement of the
 Funds' historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all investment objectives and policies not specifically designated as
 fundamental are non-fundamental and may be changed without shareholder
 approval. If there is a change in a Fund's investment objective, you should
 consider whether that Fund remains an appropriate investment in light of
 your then current financial position and needs.
 
 B. Other Portfolio Risks
 
 
 Risks of Investing in Small Capitalization Companies and REITs. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such securities. Small capitalization companies
 and REITs may be thinly traded and may have to be sold at a discount from
 current market prices or in small lots over an extended period of time. In
 addition, these securities are subject to the risk that during certain peri-
 ods the liquidity of particular issuers or industries, or all securities in
 these investment categories, will shrink or disappear suddenly and without
 warning as a result of adverse economic or market conditions, or adverse
 investor perceptions whether or not accurate. Because of the lack of suffi-
 cient market liquidity, a Fund may incur losses because it will be required
 to effect sales at a disadvantageous time and only then at a substantial
 drop in price. Small capitalization companies and REITs include "unseasoned"
 issuers that do not have an established financial history; often have lim-
 ited product lines, markets or financial resources; may depend on or use a
 few key personnel for management; and may be susceptible to losses and risks
 of bankruptcy. Transaction costs for these investments are often higher than
 those of larger capitalization companies. Investments in small capitaliza-
 tion companies and REITs may be more difficult to price precisely than other
 types of securities because of their characteristics and lower trading vol-
 umes.

 Risks of Foreign Investments. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts after January 1, 1999 that refer to existing currencies
 rather than the euro; the establishment and maintenance of exchange rates
 for currencies being converted into the euro; the fluctuation of the euro
 relative to non-euro currencies during the transition period from January 1,
 1999 to December 31, 2001 and beyond; whether the interest rate, tax and
 labor regimes of European countries participating in the euro will converge
 over time; and whether the conversion of the currencies of other countries
 that now are or may in the future become members of the European Union
 ("EU"), may have an impact on the euro. These or other factors, including
 political and economic risks, could cause market disruptions, and could
 adversely affect the value of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Efforts in foreign countries to remediate potential Year
 
                                                                              53

 2000 problems are not as extensive as those in the United States. As a
 result, the operations of foreign markets, foreign issuers and foreign gov-
 ernments may be disrupted by the Year 2000 Problem, and the investment port-
 folio of a Fund may be adversely affected. Furthermore, with respect to cer-
 tain foreign countries, there is a possibility of nationalization,
 expropriation or confiscatory taxation, imposition of withholding or other
 taxes on dividend or interest payments (or, in some cases, capital gains),
 limitations on the removal of funds or other assets of the Funds, and polit-
 ical or social instability or diplomatic developments which could affect
 investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such debt, and a Fund may have limited recourse to compel
 payment in the event of a default. Periods of economic uncertainty may
 result in the volatility of market prices of sovereign debt, and in turn a
 Fund's NAV, to a greater extent than the volatility inherent in debt obliga-
 tions of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Funds may also invest in European Depository
 Receipts ("EDRs") or other similar instruments representing securities of
 foreign issuers. ADRs represent the right to receive securities of foreign
 issuers deposited in a domestic bank or a correspondent bank. Prices of ADRs
 are quoted in U.S. dollars, and ADRs are traded in the United States. EDRs
 and GDRs are receipts evidencing an arrangement with a non-U.S. bank. EDRs
 and GDRs are not necessarily quoted in the same currency as the underlying
 security.
 
 Risks of Emerging Countries. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are gener-

                                                                      APPENDIX A
 
 ally located in the Asia-Pacific region, Eastern Europe, Latin and South
 America and Africa. A Fund's purchase and sale of portfolio securities in
 certain emerging countries may be constrained by limitations as to daily
 changes in the prices of listed securities, periodic trading or settlement
 volume and/or limitations on aggregate holdings of foreign investors. Such
 limitations may be computed based on the aggregate trading volume by or
 holdings of a Fund, the Investment Adviser, its affiliates and their respec-
 tive clients and other service providers. A Fund may not be able to sell
 securities in circumstances where price, trading or settlement volume limi-
 tations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, it is anticipated that
 a Fund may invest in such countries through other investment funds in such
 countries.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and
 
                                                                              55
<PAGE>
 
 
 ethnic, religious and racial disaffection, among other factors, have also
 led to social unrest, violence and/or labor unrest in some emerging coun-
 tries. Unanticipated political or social developments may result in sudden
 and significant investment losses. Investing in emerging countries involves
 greater risk of loss due to expropriation, nationalization, confiscation of
 assets and property or the imposition of restrictions on foreign investments
 and on repatriation of capital invested.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Fund in emerging countries may not be as sound as the
 creditworthiness of firms used in more developed countries. As a result, the
 Fund may be subject to a greater risk of loss if a securities firm defaults
 in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than investments in countries with more developed securities mar-
 kets (such as the United States, Japan and most Western European countries).
 A Fund's investments in emerging countries are subject to the risk that the
 liquidity of a particular investment, or investments generally, in such
 countries will shrink or disappear suddenly and without warning as a result
 of adverse economic, market or political conditions or adverse investor per-
 ceptions, whether or not accurate. Because of the lack of sufficient market
 liquidity, a Fund may incur losses because it will be required to effect
 sales at a disadvantageous time and only then at a substantial drop in
 price. Investments in emerging countries may be more difficult to price pre-
 cisely because of the characteristics discussed above and lower trading vol-
 umes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.

 Risks of Derivative Investments. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities and currency transactions involve additional risk of
 loss. Loss can result from a lack of correlation between changes in the
 value of derivative instruments and the portfolio assets (if any) being
 hedged, the potential illiquidity of the markets for derivative instruments,
 or the risks arising from margin requirements and related leverage factors
 associated with such transactions. The use of these management techniques
 also involves the risk of loss if the Investment Adviser is incorrect in its
 expectation of fluctuations in securities prices, interest rates or currency
 prices. Each Fund may also invest in derivative investments for non-hedging
 purposes (that is, to seek to increase total return). Investing for non-
 hedging purposes is considered a speculative practice and presents even
 greater risk of loss.
 
 Risks of Illiquid Securities. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of
  more than seven days
 .Certain over-the-counter options
 .Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that such
  restricted security is eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 Credit Risks. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Further informa-
 tion is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse
 
                                                                              57
<PAGE>
 
 
 economic conditions or changing circumstances may weaken their issuers'
 capacity to pay interest and repay principal. A security will be deemed to
 have met a rating requirement if it receives the minimum required rating
 from at least one such rating organization even though it has been rated
 below the minimum rating by one or more other rating organizations, or if
 unrated by such rating organizations, determined by the Investment Adviser
 to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 Temporary Investment Risks. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 .U.S. government securities
 .Commercial paper rated at least A-2 by Standard & Poor's or P-2 by Moody's
 .Certificates of deposit
 .Bankers' acceptances
 .Repurchase agreements
 .Non-convertible preferred stocks and non-convertible corporate bonds with a
  remaining maturity of less than one year
 
 When a Fund's assets are invested in such instruments, the Fund may not be
 achieving its investment objective.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 Convertible Securities. Each Fund may invest in convertible securities. Con-
 vertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which a Fund invests are subject to the same
 rating criteria as its other investments in
 
58
<PAGE>
 
                                                                      APPENDIX A
 
 fixed-income securities. Convertible securities have both equity and fixed-
 income risk characteristics. Like all fixed-income securities, the value of
 convertible securities is susceptible to the risk of market losses attribut-
 able to changes in interest rates. Generally, the market value of convert-
 ible securities tends to decline as interest rates increase and, conversely,
 to increase as interest rates decline. However, when the market price of the
 common stock underlying a convertible security exceeds the conversion price
 of the convertible security, the convertible security tends to reflect the
 market price of the underlying common stock. As the market price of the
 underlying common stock declines, the convertible security, like a fixed-
 income security, tends to trade increasingly on a yield basis, and thus may
 not decline in price to the same extent as the underlying common stock.
 
 Foreign Currency Transactions. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, certain Funds may also
 enter into such transactions to seek to increase total return, which is con-
 sidered a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in connection with investments in foreign securities when, in the
 judgment of the Investment Adviser, it would be beneficial to convert such
 currency into U.S. dollars at a later date (e.g., the Investment Adviser may
 anticipate the foreign currency to appreciate against the U.S. dollar).
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are
 
                                                                              59
<PAGE>
 
 
 not guaranteed by an exchange or clearinghouse, a default on a contract
 would deprive a Fund of unrealized profits, transaction costs or the bene-
 fits of a currency hedge or could force the Fund to cover its purchase or
 sale commitments, if any, at the current market price.
 
 Structured Securities. Each Fund may invest in structured securities. Struc-
 tured securities are securities whose value is determined by reference to
 changes in the value of specific currencies, interest rates, commodities,
 indices or other financial indicators (the "Reference") or the relative
 change in two or more References. The interest rate or the principal amount
 payable upon maturity or redemption may be increased or decreased depending
 upon changes in the applicable Reference. Structured securities may be posi-
 tively or negatively indexed, so that appreciation of the Reference may pro-
 duce an increase or decrease in the interest rate or value of the security
 at maturity. In addition, changes in the interest rates or the value of the
 security at maturity may be a multiple of changes in the value of the Refer-
 ence. Consequently, structured securities may present a greater degree of
 market risk than other types of fixed-income securities and may be more vol-
 atile, less liquid and more difficult to price accurately than less complex
 securities.
 
 REITs. Each Fund may invest in REITS. REITS are pooled investment vehicles
 that invest primarily in either real estate or real estate related loans.
 The value of a REIT is affected by changes in the value of the properties
 owned by the REIT or securing mortgage loans held by the REIT. REITs are
 dependent upon the ability of the REITs' managers, and are subject to heavy
 cash flow dependency, default by borrowers and the qualification of the
 REITs under applicable regulatory requirements for favorable income tax
 treatment. REITs are also subject to risks generally associated with invest-
 ments in real estate including possible declines in the value of real
 estate, general and local economic conditions, environmental problems and
 changes in interest rates. To the extent that assets underlying a REIT are
 concentrated geographically, by property type or in certain other respects,
 these risks may be heightened. A Fund will indirectly bear its proportionate
 share of any expenses, including management fees, paid by a REIT in which it
 invests.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which they may invest or on any securities index comprised of
 securities in which they may invest. A Fund may
 
60
<PAGE>
 
                                                                      APPENDIX A
 
 also, to the extent that it invests in foreign securities, purchase and sell
 (write) put and call options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater illiquidity and credit risks.
 
 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 government securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their term structures, sector selec-
 tion and durations in accordance with their investment objectives and poli-
 cies. Each Fund may also enter into closing purchase and sale transactions
 with respect to such contracts and options. A Fund will engage in futures
 and related options transactions for bona fide hedging purposes as defined
 in regulations of the Commodity Futures Trading Commission or to seek to
 increase total return to the extent permitted by such regulations. A Fund
 may not purchase or sell futures contracts or purchase or sell related
 options to seek to increase total return, except for closing purchase or
 sale transactions, if immediately thereafter the sum of the amount of ini-
 tial margin deposits and premiums paid on the Fund's outstanding positions
 in futures and related options entered
 
                                                                              61
<PAGE>
 
 
 into for the purpose of seeking to increase total return would exceed 5% of
 the market value of the Fund's net assets.
 
 Futures contracts and related options present the following risks:
 .While a Fund may benefit from the use of futures and options on futures,
  unanticipated changes in interest rates, securities prices or currency
  exchange rates may result in poorer overall performance than if the Fund
  had not entered into any futures contracts or options transactions.
 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and a Fund may be exposed to additional risk
  of loss.
 .The loss incurred by a Fund in entering into futures contracts and in writ-
  ing call options on futures is potentially unlimited and may exceed the
  amount of the premium received.
 .Futures markets are highly volatile and the use of futures may increase the
  volatility of a Fund's NAV.
 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to a Fund.
 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.
 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 Equity Swaps. Each Fund may invest in equity swaps. Equity swaps allow the
 parties to a swap agreement to exchange the dividend income or other compo-
 nents of return on an equity investment (for example, a group of equity
 securities or an index) for a component of return on another non-equity or
 equity investment.
 
 An equity swap may be used by a Fund to invest in a market without owning or
 taking physical custody of securities in circumstances in which direct
 investment may be restricted for legal reasons or is otherwise impractical.
 Equity swaps are derivatives and their value can be very volatile. To the
 extent that the Investment Adviser does not accurately analyze and predict
 the potential relative fluctuation of the components swapped with another
 party, a Fund may suffer a loss. The value of some components of an equity
 swap (such as the dividends on a common stock) may also be sensitive to
 changes in interest rates. Furthermore, a Fund may suffer a loss if the
 counterparty defaults.
 
 When-Issued Securities and Forward Commitments. Each Fund may purchase when-
 issued securities and make contracts to purchase or sell securities for a
 fixed price at a future date beyond customary settlement time. When-issued
 securities are securities that have been authorized, but not yet issued.
 When-issued securities are purchased in order to secure what is considered
 to be an advantageous price

                                                                      APPENDIX A
 
 and yield to the Fund at the time of entering into the transaction. A for-
 ward commitment involves the entering into a contract to purchase or sell
 securities for a fixed price at a future date beyond the customary settle-
 ment period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with primary dealers in U.S. government securities and member banks of the
 Federal Reserve System which furnish collateral at least equal in value or
 market price to the amount of their repurchase obligation.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's costs associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Certain
 Funds, together with other registered investment companies having advisory
 agreements with the Investment Adviser or any of its affiliates, may trans-
 fer uninvested cash balances into a single joint account, the daily aggre-
 gate balance of which will be invested in one or more repurchase agreements.
 
 Lending of Portfolio Securities. Each Fund may engage in securities lending.
 Securities lending involves the lending of securities owned by a Fund to
 financial institutions such as certain broker-dealers. The borrowers are
 required to secure their loan continuously with cash, cash equivalents, U.S.
 government securities or letters of credit in an amount at least equal to
 the market value of the securities loaned. Cash collateral may be invested
 in cash equivalents. If the Investment Adviser determines to make securities
 loans, the value of the securities loaned may not exceed 33 1/3% of the
 value of the total assets of a Fund (including the loan collateral).
 
                                                                              63
<PAGE>
 
 
 
 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 Short Sales Against-the-Box. Certain Funds may make short sales against-the-
 box. A short sale against-the-box means that at all times when a short posi-
 tion is open the Fund will own an equal amount of securities sold short, or
 securities convertible into or exchangeable for, without payment of any fur-
 ther consideration, an equal amount of the securities of the same issuer as
 the securities sold short.
 
 Preferred Stock, Warrants and Rights. Each Fund may invest in preferred
 stock, warrants and rights. Preferred stocks are securities that represent
 an ownership interest providing the holder with claims on the issuer's earn-
 ings and assets before common stock owners but after bond owners. Unlike
 debt securities, the obligations of an issuer of preferred stock, including
 dividend and other payment obligations, may not typically be accelerated by
 the holders of such preferred stock on the occurrence of an event of default
 or other non-compliance by the issuer of the preferred stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.
 
 Other Investment Companies. Each Fund may invest in securities of other
 investment companies (including SPDRs and WEBs, as defined below) subject to
 statutory limitations prescribed by the Act. These limitations include a
 prohibition on any Fund acquiring more than 3% of the voting shares of any
 other investment company, and a prohibition on investing more than 5% of a
 Fund's total assets in securities of any one investment company or more than
 10% of its total assets in securities of all investment companies. A Fund
 will indirectly bear its proportionate share of any management fees and
 other expenses paid by such other investment companies. Such other invest-
 ment companies will have investment objectives, policies and restrictions
 substantially similar to those of the acquiring Fund and will be subject to
 substantially the same risks.
 
 .Standard & Poor's Depository Receipts. The Funds may, consistent with their
  investment policies, purchase Standard & Poor's Depository Receipts
  ("SPDRs"). SPDRs are securities traded on the American Stock Exchange
  ("AMEX") that represent ownership in the SPDR Trust, a trust which has been
  established to accumulate and hold a portfolio of common stocks that is
  intended to track the price performance and dividend yield of the S&P 500.
  The SPDR Trust is sponsored by a subsidiary of the AMEX. SPDRs may be used
  for several reasons, including, but not limited to, facilitating the han-
  dling of

  cash flows or trading, or reducing transaction costs. The price movement of
  SPDRs may not perfectly parallel the price action of the S&P 500.
 
 .World Equity Benchmark Shares. World Equity Benchmark Shares ("WEBS") are
  shares of an investment company that invests substantially all of its
  assets in securities included in the MSCI indices for specified countries.
  WEBS are listed on the AMEX and were initially offered to the public in
  1996. The market prices of WEBS are expected to fluctuate in accordance
  with both changes in the NAVs of their underlying indices and supply and
  demand of WEBS on the AMEX. To date, WEBS have traded at relatively modest
  discounts and premiums to their NAVs. However, WEBS have a limited operat-
  ing history and information is lacking regarding the actual performance and
  trading liquidity of WEBS for extended periods or over complete market
  cycles. In addition, there is no assurance that the requirements of the
  AMEX necessary to maintain the listing of WEBS will continue to be met or
  will remain unchanged. In the event substantial market or other disruptions
  affecting WEBS should occur in the future, the liquidity and value of a
  Fund's shares could also be substantially and adversely affected. If such
  disruptions were to occur, a Fund could be required to reconsider the use
  of WEBS as part of its investment strategy.
 
 Unseasoned Companies. Each Fund may invest in companies (including predeces-
 sors) which have operated less than three years, except that this limitation
 does not apply to debt securities which have been rated investment grade or
 better by at least one NRSRO. The securities of such companies may have lim-
 ited liquidity, which can result in their being priced higher or lower than
 might otherwise be the case. In addition, investments in unseasoned compa-
 nies are more speculative and entail greater risk than do investments in
 companies with an established operating record.
 
 Corporate Debt Obligations. Corporate debt obligations include bonds, notes,
 debentures and other obligations of corporations to pay interest and repay
 principal, and include securities issued by banks and other financial insti-
 tutions. Each Fund may invest in corporate debt obligations issued by U.S.
 and certain non-U.S. issuers which issue securities denominated in the U.S.
 dollar (including Yankee and Euro obligations). In addition to obligations
 of corporations, corporate debt obligations include securities issued by
 banks and other financial institutions and supranational entities (i.e., the
 World Bank, the International Monetary Fund, etc.).
 
 Bank Obligations. Each Fund may invest in obligations issued or guaranteed
 by U.S. or foreign banks. Bank obligations, including without limitations,
 time deposits, bankers' acceptances and certificates of deposit, may be gen-
 eral obligations of the parent bank or may be limited to the issuing branch
 by the terms of the specific obligations or by government regulations. Banks
 are subject to extensive but
 
                                                                              65
<PAGE>
 
 
 different governmental regulations which may limit both the amount and types
 of loans which may be made and interest rates which may be charged. In addi-
 tion, the profitability of the banking industry is largely dependent upon
 the availability and cost of funds for the purpose of financing lending
 operations under prevailing money market conditions. General economic condi-
 tions as well as exposure to credit losses arising from possible financial
 difficulties of borrowers play an important part in the operation of this
 industry.
 
 U.S. Government Securities and Related Custodial Receipts. Each Fund may
 invest in U.S. government securities and related custodial receipts. U.S.
 government securities include U.S. Treasury obligations and obligations
 issued or guaranteed by U.S. government agencies, instrumentalities or spon-
 sored enterprises. U.S. government securities may be supported by (a) the
 full faith and credit of the U.S. Treasury (such as the Government National
 Mortgage Association ("Ginnie Mae")); (b) the right of the issuer to borrow
 from the U.S. Treasury (such as securities of the Student Loan Marketing
 Association); (c) the discretionary authority of the U.S. government to pur-
 chase certain obligations of the issuer (such as the Federal National Mort-
 gage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. government
 securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. government securities, where the interest and principal compo-
 nents of stripped U.S. government securities are traded independently.
 
 Interests in U.S. government securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S.
 government.
 
 Mortgage-Backed Securities. Certain Funds may invest in mortgage-backed
 securities. Mortgage-backed securities represent direct or indirect partici-
 pations in, or are collateralized by and payable from, mortgage loans
 secured by real property. Mortgage-backed securities can be backed by either
 fixed rate mortgage loans or adjustable rate mortgage loans, and may be
 issued by either a governmental or non-governmental entity. Privately issued
 mortgage-backed securities are normally structured with one or more types of
 "credit enhancement." However, these mortgage-backed securities typically do
 not have the same credit standing as U.S. government guaranteed mortgage-
 backed securities.
 
 Mortgage-backed securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an

                                                                      APPENDIX A
 
 investor with a specified interest in the cash flow from a pool of under-
 lying mortgages or of other mortgage-backed securities. CMOs are issued in
 multiple classes. In most cases, payments of principal are applied to the
 CMO classes in the order of their respective stated maturities, so that no
 principal payments will be made on a CMO class until all other classes hav-
 ing an earlier stated maturity date are paid in full. A REMIC is a CMO that
 qualifies for special tax treatment and invests in certain mortgages princi-
 pally secured by interests in real property and other permitted investments.
 
 Mortgaged-backed securities also include stripped mortgage-backed securities
 ("SMBS"), which are derivative multiple class mortgage-backed securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other mortgage-backed securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 Asset-Backed Securities. Certain Funds may invest in asset-backed securi-
 ties. Asset-backed securities are securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed securities are often subject to more rapid repayment than their
 stated maturity date would indicate as a result of the pass-through of pre-
 payments of principal on the underlying loans. During periods of declining
 interest rates, prepayment of loans underlying asset-backed securities can
 be expected to accelerate. Accordingly, a Fund's ability to maintain posi-
 tions in such securities will be affected by reductions in the principal
 amount of such securities resulting from prepayments, and its ability to
 reinvest the returns of principal at comparable yields is subject to gener-
 ally prevailing interest rates at that time. Asset-backed securities present
 credit risks that are not presented by mortgage-backed securities. This is
 because asset-backed securities generally do not have the benefit of a secu-
 rity interest in collateral that is comparable to mortgage assets. There is
 the possibility that, in some cases, recoveries on repossessed collateral
 may not be available to support payments on these securities. In the event
 of a default, a Fund may suffer a loss if it cannot sell collateral quickly
 and receive the amount it is owed.
 
 Borrowings. Each Fund can borrow money from banks and other financial insti-
 tutions in amounts not exceeding one-third of their total assets for tempo-
 rary or emergency purposes. A Fund may not make additional investments if
 borrowings exceed 5% of its total assets.
 
                                                                              67

Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

Prior Performance of Similarly Advised Accounts of the Investment Adviser
 
 EUROPEAN EQUITY FUND
 The following table sets forth the Investment Adviser's composite perfor-
 mance data relating to the historical performance of all discretionary pri-
 vate accounts managed by the Investment Adviser that have investment objec-
 tives, policies and strategies substantially similar to the European Equity
 Fund. The information is provided to illustrate the past performance of the
 Investment Adviser in managing substantially similar accounts as measured
 against the FT/S&P Actuaries Europe Index (unhedged) and does not represent
 the performance of the European Equity Fund. Investors should not consider
 this performance data as a substitute for the performance of the European
 Equity Fund nor should investors consider this data as an indication of
 future performance of the European Equity Fund or of the Investment Adviser.
 The FT/S&P Actuaries Europe Index (unhedged) is unmanaged and investors can-
 not invest directly in the Index.

 In accordance with the standards of the Association for Investment Manage-
 ment and Research ("AIMR"), the Investment Adviser's composite performance
 information was calculated on a time-weighted and asset-weighted total
 return basis

<PAGE>
 
                                                                      APPENDIX C
 
 which includes realized and unrealized gains and losses plus income. The
 composite performance is net of applicable investment management fees, bro-
 kerage commissions, execution costs and custodial fees, without provision
 for federal and state taxes, if any. Total return performance of the Euro-
 pean Equity Fund will be calculated in accordance with the regulations of
 the SEC. The SEC standardized average annual total return is neither time-
 weighted nor asset-weighted and is determined for specified periods by com-
 puting the annualized percentage change in the value of an initial amount
 that is invested in a share class of the Fund at the maximum public offering
 price. Investors should be aware that the differences in methodology between
 AIMR and SEC requirements could result in different performance data for
 identical time periods.
 
 All returns presented reflect the reinvestment of dividends and other earn-
 ings. The weighted-average expenses of the private accounts used in calcu-
 lating the Investment Adviser's net composite performance data were 0.46%
 annualized, which are lower than the estimated expenses of Institutional
 Shares of the European Equity Fund stated under "Fund Fees and Expenses"
 above. The performance of the private accounts would have been lower if they
 had been subject to the expenses of the European Equity Fund. In addition,
 the private accounts are not subject to the same diversification require-
 ments, specific tax restrictions and investment limitations imposed on the
 European Equity Fund by the Act and Subchapter M of the Code. Consequently,
 the performance results of the Investment Adviser's composite could have
 been adversely affected if the private accounts had been regulated as
 investment companies under the federal securities laws.

 The Investment Adviser attempts to manage risk in these Funds through disci-
 plined portfolio construction and continual portfolio review and analysis.
 As a result, bottom-up stock selection, driven by fundamental research,
 should be a main driver of returns.

 QUANTITATIVE ("CORE") STYLE FUNDS
 
 
 Goldman Sachs' CORE Investment Philosophy:
 Goldman Sachs' quantitative style of funds--CORE--emphasizes the two build-
 ing blocks of active management: stock selection and portfolio construction.
 
 I. Core Stock Selection
 The CORE Funds use the Goldman Sachs proprietary multifactor model
 ("Multifactor Model"), a rigorous computerized rating system, to forecast
 returns on securities held in each Fund's portfolio. The Multifactor Model
 incorporates common variables covering measures of:
 .Value (price-to-book, price-to-earnings, cash flow to enterprise value)
 .Momentum (earnings momentum, price momentum, sustainable growth)
 .Risk (market risk, company-specific risk, earnings risk)
 
 All of the above factors are carefully evaluated within the Multifactor
 Model since each has demonstrated a significant impact on the performance of
 the securities and markets they were designed to forecast.
 
 II. Core Portfolio Construction
 A proprietary computer optimizer calculates every security combination (at
 every possible weighting) to construct the most efficient risk/return port-
 folio given each CORE Fund benchmark. In this process, the Investment
 Adviser manages risk by limiting deviations from the benchmark.
 
 Goldman Sachs CORE Funds are fully invested, broadly diversified and offer
 consistent overall portfolio characteristics. They may serve as good founda-
 tions on which to build a portfolio.

 INVESTMENT OBJECTIVE
 
 The Fund seeks long-term growth of capital. The Fund seeks this objective
 through a broadly diversified portfolio of equity securities of large-cap
 companies that are organized outside the United States or whose securities
 are principally traded outside the United States.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, at least
 90% of its total assets in equity securities of companies that are organized
 outside the United States or whose securities are principally traded outside
 the United States.
 The Fund may allocate its assets among countries as determined by the
 Investment Adviser from time to time, provided the Fund's assets are
 invested in at least three foreign countries. The Fund may invest in the
 securities of issuers in countries with emerging markets or economies
 ("emerging countries").
 The Fund seeks broad representation of large-cap issuers across major coun-
 tries and sectors of the international economy. The Fund's investments are
 selected using both a variety of quantitative techniques and fundamental
 research in seeking to maximize the Fund's expected return, while maintain-
 ing risk, style, capitalization and industry characteristics similar to the
 EAFE Index. In addition, the Fund seeks a portfolio composed of companies
 with attractive valuations and stronger momentum characteristics than the
 EAFE Index.
 Other. The Fund's investments in fixed-income securities are limited to
 securities that are considered to be cash equivalents.

 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 companies that are organized outside the United States or whose securities
 are principally traded outside the United States. The Fund intends to invest
 in companies with public stock market capitalizations that are larger than
 $1 billion at the time of investment.
 
 The Fund may allocate its assets among countries as determined by the
 Investment Adviser from time to time provided that the Fund's assets are
 invested in at least three foreign countries.
 
 The Fund expects to invest a substantial portion of its assets in the secu-
 rities of issuers located in the developed countries of Western Europe and
 in Japan. However, the Fund may also invest in the securities of issuers
 located in Australia, Canada, New Zealand and emerging countries. Currently,
 emerging countries include among others, most Latin American, African, Asian
 and Eastern European nations.
 
 Other. The Fund may also invest up to 35% of its total assets in fixed-
 income securities, such as corporate debt and bank obligations.

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 European companies. Because of its focus, the Fund will be more susceptible
 to European economic, market, political and local risks than a fund that is
 more geographically diversified.
 
 A European issuer is a company that either:
 .Has a class of its securities whose principal securities markets is in a
  European country;
 .Is organized under the laws of, or has a principal office in, a European
  country;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in one or more of the European countries; or
 .Maintains 50% or more of its assets in one or more of the European coun-
  tries.
 
 The Fund may allocate its assets among different countries as determined by
 the Investment Adviser from time to time, provided that the Fund's assets
 are invested in at least three European countries. It is currently antici-
 pated that a majority of the Fund's assets will be invested in the equity
 securities of large cap companies located in the developed countries of
 Western Europe. However, the Fund may also invest, without limit, in mid cap
 companies and small cap companies, as well as companies located in emerging
 countries. Currently, emerging countries include among others, most Latin
 American, African, Asian, most Eastern European nations, including the
 states that formerly comprised the Soviet Union and Yugoslavia.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of non-European countries and in fixed-income securities,
 such as corporate debt and bank obligations.

 INVESTMENT OBJECTIVE
 
 
 The Fund seeks long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGIES
 
 
 Equity Securities. The Fund invests, under normal circumstances, substan-
 tially all, and at least 65% of its total assets in equity securities of
 Japanese companies. A Japanese issuer is a company that either:
 .Has a class of its securities whose principal securities markets is in
  Japan;
 .Is organized under the laws of, or has a principal office in Japan;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in Japan; or
 .Maintains 50% or more of its assets in Japan.
 
 The Fund's concentration in Japanese companies will expose it to the risk of
 adverse social, political and economic events which occur in Japan or affect
 the Japanese markets.
 
 Japan's economy, the second largest in the world, has grown substantially
 over the last three decades. Since 1990, however, Japan's economic growth
 has declined significantly, and is currently subject to deflationary pres-
 sures. In addition to this economic downturn, Japan is undergoing structural
 adjustments related to high wages and taxes, currency valuations and struc-
 tural rigidities. Japan has also been experiencing notable uncertainty and
 loss of public confidence in connection with the reform of its political
 process and the deregulation of its economy. These conditions present risks
 to the Japanese Equity Fund and its ability to attain its investment objec-
 tive.

                                       FUND INVESTMENT OBJECTIVES AND STRATEGIES
 
 
 
 Japan's economy is heavily dependent upon international trade, and is espe-
 cially sensitive to trade barriers and disputes. In particular, Japan relies
 on large imports of agricultural products, raw materials and fuels. A sub-
 stantial rise in world oil or commodity prices, or a fall-off in Japan's
 manufactured exports, could be expected to adversely affect Japan's economy.
 In addition, Japan is vulnerable to earthquakes, volcanoes and other natural
 disasters. As of the date of this Prospectus, Japan's banking industry con-
 tinued to suffer from non-performing loans, declining real estate values and
 lower valuations of securities holdings.
 
 The Japanese securities markets are less regulated than the U.S. markets.
 Evidence has emerged from time to time of distortion of market prices to
 serve political or other purposes. Shareholders' rights are also not always
 equally enforced.
 
 The common stocks of many Japanese companies trade at high price-earnings
 ratios. Differences in accounting methods make it difficult to compare the
 earnings of Japanese companies with those of companies in other countries,
 especially the United States. In general, however, reported net income in
 Japan is understated relative to U.S. accounting standards and this is one
 reason price-earnings ratios of the stocks of Japanese companies have tended
 historically to be higher than those of U.S. stocks. In addition, Japanese
 companies have tended to have higher growth rates than U.S. companies, and
 Japanese interest rates have generally been lower than U.S. interest rates.
 These factors have contributed to lower discount rates and higher price-
 earnings ratios in Japan than in the United States.
 
 During the recent past the average stock market prices of Japanese compa-
 nies, as measured by major indices such as the NIKKEI 225 Average, have
 experienced a substantial decline. It is not possible to determine whether
 this general decline will continue.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of non-Japanese companies and in fixed-income securities,
 such as corporate debt and bank obligations.

 ket capitalization of a company held by the Fund increases above $1 billion,
 the Fund may, consistent with its investment objective, continue to hold the
 security.

 Adviser currently intends that the Fund's investment focus will be in the
 following emerging countries as well as any other emerging country to the
 extent that foreign investors are permitted by applicable law to make such
 investments:

 An emerging country issuer is any company that either:
 .Has a class of its securities whose principal securities market is in an
  emerging country;
 .Is organized under the laws of, or has a principal office in, an emerging
  country;
 .Derives 50% or more of its total revenue from goods produced, sales made or
  services performed in one or more emerging countries; or
 .Maintains 50% or more of its assets in one or more of the emerging coun-
  tries.
 
 Under normal circumstances, the Fund maintains investments in at least six
 emerging countries, and will not invest more than 35% of its total assets in
 securities of issuers in any one emerging country. Allocation of the Fund's
 investments will depend upon the relative attractiveness of the emerging
 country markets and particular issuers. In addition, macro-economic factors
 and the portfolio managers' and Goldman Sachs economists' views of the rela-
 tive attractiveness of emerging countries and currencies are considered in
 allocating the Fund's assets among emerging countries.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 (i) fixed-income securities, such as corporate debt and bank obligations, of
 private and governmental emerging country issuers; and (ii) equity and
 fixed-income securities, such as corporate debt and bank obligations, of
 issuers in developed countries.

Goldman Sachs Asia Growth Fund continued
 
 
 Allocation of the Fund's investments will depend upon the Investment Advis-
 er's views of the relative attractiveness of the Asian markets and particu-
 lar issuers.
 
 Concentration of the Fund's assets in one or a few of the Asian countries
 and Asian currencies will subject the Fund to greater risks than if the
 Fund's assets were not so concentrated. For example, on January 31, 1999
 (the end of the Fund's last fiscal year), more than 25% of the Fund's assets
 were invested in securities that traded in Hong Kong.
 
 Starting in mid-1997 some Pacific region countries began to experience cur-
 rency devaluations that resulted in high interest rate levels and sharp
 reductions in economic activity. This situation resulted in a significant
 drop in the securities prices of companies located in the region. Some coun-
 tries have experienced government intervention, have sought assistance from
 the International Monetary Fund and are undergoing substantial domestic
 unrest. Although some countries are taking steps to restructure their finan-
 cial sectors in a manner that may facilitate a return to long-term economic
 growth, there can be no assurance that these efforts will be successful or
 that their current problems will not persist. At the end of its last fiscal
 year, a substantial portion of the Asia Growth Fund was invested in securi-
 ties traded in the Hong Kong market. In 1997, the sovereignty of Hong Kong
 reverted from the United Kingdom to China. Although Hong Kong is, by law, to
 maintain a high degree of autonomy, there can also be no assurance that the
 general economic position of Hong Kong will not be adversely affected as a
 result of the exercise of Chinese sovereignty over Hong Kong. In particular,
 business confidence in Hong Kong can be significantly affected by political
 developments and statements by public figures in China, which can in turn
 affect the performance of the securities markets. In addition, the reversion
 of Hong Kong to China has created uncertainty as to future currency valua-
 tions relative to the U.S. dollar. Any future valuation changes could be
 adverse from the perspective of U.S. investors.
 
 Other. The Fund may invest in the aggregate up to 35% of its total assets in
 equity securities of issuers in other countries, including Japan, and in
 fixed-income securities, such as corporate debt and bank obligations.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other governmental agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete
investment program. There can be no assurance that a Fund will achieve its
investment objective.

All Funds:
 
 .Credit/Default Risk--The risk that an issuer of fixed-income securities held
 by a Fund (which may have low credit ratings) may default on its obligation to
 pay interest and repay principal.
 .Emerging Countries Risk--The securities markets of Asian, Latin American,
 Eastern European, African and other emerging countries are less liquid, are
 especially subject to greater price volatility, have smaller market capital-
 izations, have less government regulation and are not subject to as extensive
 and frequent accounting, financial and other reporting requirements as the
 securities markets of more developed countries. Further, investment in equity
 securities of issuers located in Russia and certain other emerging countries
 involves risk of loss resulting from problems in share registration and cus-
 tody and substantial economic and political disrup-

 tions. These risks are not normally associated with investment in more devel-
 oped countries.
 .Interest Rate Risk--The risk that when interest rates increase, fixed-income
 securities held by a Fund will decline in value. Long-term fixed-income secu-
 rities will normally have more price volatility because of this risk than
 short-term securities.
 .Foreign Risks--The risk that when a Fund invests in foreign securities, it
 will be subject to risks not typically associated with domestic issuers. Loss
 may result because of less foreign government regulation, less public informa-
 tion and less economic, political and social stability. Loss may also result
 from the imposition of exchange controls, confiscations and other government
 restrictions. A Fund will also be subject to the risk of negative foreign cur-
 rency rate fluctuations. Foreign risks will normally be greatest when a Fund
 invests in issuers located in emerging countries.
 .Derivatives Risk--The risk that loss may result from a Fund's investments in
 options, futures, swaps, structured securities and other derivative instru-
 ments. These instruments may be leveraged so that small changes may produce
 disproportionate losses to a Fund.
 .Management Risk--The risk that a strategy used by the Investment Adviser may
 fail to produce the intended results.
 .Market Risk--The risk that the value of the securities in which a Fund invests
 may go up or down in response to the prospects of individual companies and/or
 general economic conditions. Price changes may be temporary or last for
 extended periods.
 .Liquidity Risk--The risk that a Fund will not be able to pay redemption pro-
 ceeds within the time period stated in this Prospectus, because of unusual
 market conditions, an unusually high volume of redemption requests, or other
 reasons. Funds that invest in small capitalization stocks and emerging country
 issuers will be especially subject to the risk that during certain periods the
 liquidity of particular issuers or industries, or all securities within these
 investment categories, will shrink or disappear suddenly and without warning
 as a result of adverse economic, market or political events, or adverse
 investor perceptions whether or not accurate.
 .Stock Risk--The risk that stock prices have historically risen and fallen in
 periodic cycles. As of the date of this Prospectus, U.S. stock markets and
 certain foreign stock markets were trading at or close to record high levels.
 There is no guarantee that such levels will continue.
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
                                                                              19
<PAGE>
 
 
Specific Funds:
 .Small Cap Stock Risk--The securities of small capitalization stocks involve
 greater risks than those associated with larger, more established companies
 and may be subject to more abrupt or erratic price movements. Securities of
 such issuers may lack sufficient market liquidity to enable a Fund to effect
 sales at an advantageous time or without a substantial drop in price.
 .Geographic Risk--The European Equity Fund invests primarily in equity securi-
 ties of European companies. The Japanese Equity Fund invests primarily in
 equity securities of Japanese equity companies. The Asia Growth Fund invests
 primarily in equity securities of Asian issuers. Concentration of the invest-
 ments of these or other Funds in issuers located in a particular country or
 region will subject the Fund, to a greater extent than if investments were
 less concentrated, to the risks of adverse securities markets, exchange rates
 and social, political, regulatory or economic events which may occur in that
 country or region.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Service
 Shares from year to year; and (b) how the average annual returns of a Fund's
 Service Shares compare to those of broad-based securities market indices.
 The bar chart and table assume reinvestment of dividends and distributions.
 A Fund's past performance is not necessarily an indication of how the Fund
 will perform in the future. Performance reflects expense limitations in
 effect. If expense limitations were not in place, a Fund's performance would
 have been reduced. The European Equity, Japanese Equity and International
 Small Cap Funds did not commence operations until October 1, 1998, May 1,
 1998 and May 1, 1998. Since these Funds have less than one calendar year's
 performance, no performance information is provided in this section. As of
 the date of this Prospectus, Service Shares of the Asia Growth Fund had not
 commenced operations. Performance of the Asia Growth Fund is represented by
 the Fund's Class A Shares. Class A Shares are not offered in this Prospectus
 but have substantially similar annual returns because the shares are
 invested in the same investment portfolio of securities. Annual returns dif-
 fer only to the extent that Class A Shares have a 0.50% distribution and
 service fee and a 0.19% transfer agency fee while Service Shares have a
 0.50% service fee and a 0.04% transfer agency fee.

tus.
/2/The Funds' annual operating expenses have been restated to reflect current
fees, except for the European Equity Fund, Japanese Equity Fund and
International Small Cap Fund whose expenses have been annualized for the
current fiscal year.
/3/Service Organizations may charge other fees to their customers who are bene-
ficial owners of Service Shares in connection with their customers' accounts.
Such fees may affect the return customers realize with respect to their invest-

/4/"Other Expenses" include transfer agency fees equal to 0.04% of the average
daily net assets of each Fund's Service Shares, plus all other ordinary
expenses not detailed above. The Investment Adviser has voluntarily agreed to
reduce or limit "Other Expenses" (excluding management fees, transfer agency
fees, service fees, taxes, interest and brokerage fees and litigation, indemni-
fication and other extraordinary expenses) to the following percentages of each
Fund's average daily net assets:

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the expense limitations) with the cost of investing in other
mutual funds. The Example assumes that you invest $10,000 in Service Shares of
a Fund for the time periods indicated and then redeem all of your Service
Shares at the end of those periods. The Example also assumes that your invest-
ment has a 5% return each year and that a Fund's operating expenses remain the
same. Although your actual costs may be higher or lower, based on these assump-
tions your costs would be:

Service Organizations that invest in Service Shares on behalf of their custom-
ers may charge other fees directly to their customer accounts in connection
with their investments. You should contact your Service Organization for infor-
mation regarding such charges. Such fees, if any, may affect the return such
customers realize with respect to their investments.
 
Certain Service Organizations that invest in Service Shares may receive other
compensation in connection with the sale and distribution of Service shares or
for services to their customers' accounts and/or the Funds. For additional
information regarding such compensation, see "Shareholder Guide" in the Pro-
spectus and "Other Information" in the Statement of Additional Information
("Additional Statement").

 GSAM is a separate operating division of Goldman Sachs, which registered as
 an investment adviser in 1981. GSAMI, a member of the Investment Management
 Regulatory Organization Limited since 1990 and a registered investment
 adviser since 1991, is an affiliate of Goldman Sachs. The Goldman Sachs
 Group, L.P., which controls the Investment Advisers, announced that it will
 pursue an initial public offering of the firm in the late spring or early
 summer of 1999. Simultaneously with the offering, the Goldman Sachs Group,
 L.P. will merge into The Goldman Sachs Group, Inc. As of February 28, 1999,
 GSAM and GSAMI, together with their affiliates, acted as investment adviser
 or distributor for assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser makes the investment decisions
 for the Funds and places purchase and sale orders for the Funds' portfolio
 transactions in U.S. and foreign markets. As permitted by applicable law,
 these orders may be directed to any brokers, including Goldman Sachs and its
 affiliates. While the Investment Adviser is ultimately responsible for the
 management of the Funds, it is able to draw upon the research and expertise
 of its asset management affiliates for portfolio decisions and management
 with respect to certain portfolio securities. In addition, the Investment
 Adviser has access to the research and certain proprietary technical models
 developed by Goldman Sachs, and will apply quantitative and qualitative
 analysis in determining the appropriate allocations among categories of
 issuers and types of securities.
 
 The Investment Adviser also performs the following additional services for
 the Funds:

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to a Fund or limit a Fund's investment activities. Goldman Sachs and its
 affiliates engage in proprietary trading and advise accounts and funds which
 have investment objectives similar to those of the Funds and/or which engage
 in and compete for transactions in the same types of securities, currencies
 and instruments as the Funds. Goldman Sachs and its affiliates will not have
 any obligation to make available any information regarding their proprietary
 activities or strategies, or the activities or strategies used for other
 accounts managed by them, for the benefit of the management of the Funds.
 The results of a Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that a Fund
 could sustain losses during periods in which Goldman Sachs and its affili-
 ates and other accounts achieve significant profits on their trading for
 proprietary or other accounts. In addition, the Funds may, from time to
 time, enter into transactions in which other clients of Goldman Sachs have
 an adverse interest. A Fund's activities may be limited because of regula-
 tory restrictions applicable to Goldman Sachs and its affiliates, and/or
 their internal policies designed to comply with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly

<PAGE>
 
                                                               SERVICE PROVIDERS
 
 known as the "Year 2000 Problem"). To the extent these systems conduct
 forward-looking calculations, these computer problems may occur prior to
 January 1, 2000. Like other investment companies and financial and business
 organizations, the Funds could be adversely affected in their ability to
 process securities trades, price securities, provide shareholder account
 services and otherwise conduct normal business operations if the Investment
 Adviser or other Fund service providers do not adequately address this prob-
 lem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
                                                                              39

Dividends
 
 Each Fund pays dividends from its net investment income and distributions
 from net realized capital gains. You may choose to have dividends and dis-
 tributions paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund.
  Special restrictions may apply for certain ILA Portfolios. See the
  Additional Statement.
 
 You may indicate your election on your Account Application. Any changes may
 be submitted in writing to Goldman Sachs at any time before the record date
 for a particular dividend or distribution. If you do not indicate any
 choice, your dividends and distributions will be reinvested automatically in
 the applicable Fund.
 
 The election to reinvest dividends and distributions in additional shares
 will not affect the tax treatment of such dividends and distributions, which
 will be treated as received by you and then used to purchase the shares.
 Under certain circumstances, the Funds may make an election to treat a pro-
 portionate amount of such taxes as constituting a distribution to you, which
 would allow you either (1) to credit such proportionate amount of taxes
 against your U.S. federal income tax liability or (2) to take such amount as
 an itemized deduction.
 
 Dividends from net investment income and distributions from net capital
 gains are declared and paid annually.
 
 From time to time a portion of a Fund's dividends may constitute a return
 of capital.
 
 At the time of an investor's purchase of shares of a Fund, a portion of the
 NAV per share may be represented by undistributed income or realized or
 unrealized appreciation of the Fund's portfolio securities. Therefore, sub-
 sequent distributions on such shares from such income or realized apprecia-
 tion may be taxable to the investor even if the NAV of the shares is, as a
 result of the distributions, reduced below the cost of such shares and the
 distributions (or portions thereof) represent a return of a portion of the
 purchase price.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Service
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Service Shares Of The Funds?
 Generally, Service Shares may be purchased only through institutions that
 have agreed to provide account administration and personal and account main-
 tenance services to their customers who are the beneficial owners of Service
 Shares. These institutions are called "Service Organizations." Customers of
 a Service Organization will normally give their purchase instructions to the
 Service Organization, and the Service Organization will, in turn, place pur-
 chase orders with Goldman Sachs. Service Organizations will set times by
 which purchase orders and payments must be received by them from their cus-
 tomers. Generally, Service Shares may be purchased from the Funds on any
 business day at their net asset value ("NAV") next determined after receipt
 of an order by Goldman Sachs from a Service Organization. No sales load is
 charged. Purchases of Service Shares must be settled within three business
 days of receipt of a complete purchase order.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place an order with Goldman Sachs at 1-800-621-2550 and either:
 .Wire federal funds to The Northern Trust Company ("Northern"), as
  subcustodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian) on the next business day; or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Northern;
  or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Service Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 
                                                                              41
<PAGE>
 
 .Responding to inquiries from prospective and existing shareholders
 .Assisting customers with investment procedures
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of Goldman Sachs Trust (the "Trust"), purchase, redemption
 and exchange orders placed by or on behalf of their customers, and may des-
 ignate other intermediaries to accept such orders, if approved by the Trust.
 In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to a service plan adopted by the Trust's Board of Trustees, Service
 Organizations are entitled to receive payment for their services from the
 Trust of up to 0.50% (on an annualized basis) of the average daily net
 assets of the Service Shares of the Funds, which are attributable to or held
 in the name of the Service Organization for its customers.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 In addition to Service Shares, each Fund also offers other classes of shares
 to investors. These other share classes are subject to different fees and
 expenses (which affect performance), have different minimum investment
 requirements and
 are entitled to different services than Service Shares. Information regard-
 ing these other share classes may be obtained from your sales representative
 or from Goldman Sachs by calling the number on the back cover of this Pro-
 spectus.

 What Is My Minimum Investment In The Funds?
 The Funds do not have any minimum purchase or account requirements with
 respect to Service Shares. A Service Organization may, however, impose a
 minimum amount for initial and subsequent investments in Service Shares, and
 may establish other requirements such as a minimum account balance. A Serv-
 ice Organization may redeem Service Shares held by non-complying accounts,
 and may impose a charge for any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Reject or restrict any purchase or exchange orders by a particular pur-
  chaser (or group of related purchasers). This may occur, for example, when
  a pattern of frequent purchases, sales or exchanges of Service Shares of a
  Fund is evident, or if purchases, sales or exchanges are, or a subsequent
  abrupt redemption might be, of a size that would disrupt the management of
  a Fund.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Service Shares
 is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                    (Value of Assets of the Class)
                     - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
 The Funds' investments are valued based on market quotations or, if accurate
 quotations are not readily available, the fair value of the Fund's invest-
 ments may be determined in good faith under procedures established by the
 Trustees.
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will not be priced on any day
  the New York Stock Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form.
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if
 
                                                                              43
<PAGE>
 
 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 In addition, the impact of events that occur after the publication of market
 quotations used by a Fund to price its securities but before the close of
 regular trading on the New York Stock Exchange will normally not be
 reflected in a Fund's next determined NAV unless the Trust, in its discre-
 tion, makes an adjustment in light of the nature and materiality of the
 event, its effect on Fund operations and other relevant factors.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Service Shares Of The Funds?
 Generally, Service Shares may be sold (redeemed) only through Service Orga-
 nizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. Generally,
 each Fund will redeem its Service Shares upon request on any business day at
 their NAV next determined after receipt of such request in proper form.
 Redemption proceeds may be sent to recordholders by check or by wire (if the
 wire instructions are on record).
 
 A Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is elected on the Account
 Application.

 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not

 ulent transactions. The following general policies are currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: The Funds will arrange for redemption proceeds to be wired as fed-
 eral funds to the bank account designated in the recordholder's Account
 Application. The following general policies govern wiring redemption pro-
 ceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If the shares to be sold were recently paid for by
  check, the Fund will pay the redemption proceeds when the check has
  cleared, which may take up to 15 days. If the Federal Reserve Bank is
  closed on the day that the redemption proceeds would ordinarily be wired,
  wiring the redemption proceeds may be delayed one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  Account Application to the Service Organization.
 .Neither the Trust, nor Goldman Sachs assume any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organization.
 
 By Check: A recordholder may elect in writing to receive redemption proceeds
 by check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of receipt of a properly exe-
 cuted redemption request. If the shares to be sold were recently paid for by
 check, the Fund will pay the redemption proceeds when the check has cleared,
 which may take up to 15 days.
 
                                                                              45

 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem the Service Shares of any Service Organization whose account balance
  falls below $50 as a result of a redemption. The Funds will not redeem
  Service Shares on this basis if the value of the account falls below the
  minimum account balance solely as a result of market conditions. The Fund
  will give 60 days' prior written notice to allow a Service Organization to
  purchase sufficient additional shares of the Fund in order to avoid such
  redemption.
 .Redeem the shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Service Shares of a Fund at NAV for
 Service Shares of any other Goldman Sachs Fund. The exchange privilege may
 be materially modified or withdrawn at any time upon 60 days' written
 notice.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirement of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will Be Sent Regarding Investments In Service Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Service Organizations
 will also be provided with a printed confirmation for each transaction in
 their account and a monthly account statement. Service Organizations are
 responsible for providing these or other reports to their customers who are
 the beneficial owners of Service Shares in accordance with the rules that
 apply to their accounts with the Service Organizations.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Fund distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Fund's net investment income, certain net realized
 foreign exchange gains and net short-term capital gains. They are taxable as
 long-term capital gains to the extent they are attributable to the Fund's
 excess of net long-term capital gains over net short-term capital losses.
 The tax status of any distribution is the same regardless of how long you
 have been in the Fund and whether you reinvest in additional shares or take
 the distribution as cash. Certain distributions paid by a Fund in January of
 a given year may be taxable to shareholders as if received the prior Decem-
 ber 31. The tax status and amounts of the distributions for each calendar
 year will be detailed in your annual tax statement from the Fund.
 
 A Fund's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Fund receives from U.S. domestic
 corporations may be eligible, in the hands of the corporate shareholders,
 for the corporate dividends-received deduction, subject to certain holding
 period requirements and debt financing limitations.
 
 Each Fund may be subject to foreign withholding or other foreign taxes on
 income or gain from certain foreign securities. In general, the Funds may
 deduct these taxes in computing their taxable income.
 
 There are certain tax requirements that all Funds must follow in order to
 avoid federal taxation. In its efforts to adhere to these requirements, the
 Funds may have to limit their investment activity in some types of instru-
 ments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Fund shares may generate a tax liability (unless
 your investment is in an IRA or other tax-advantaged account). Depending
 upon the purchase or sale price of the shares you sell or exchange, you may
 have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Fund, based on the
 difference between your tax basis in the shares and the amount you receive
 for them. (To aid in computing your tax basis, you generally should retain
 your account statements for the periods that you hold shares.) Any loss rec-
 ognized on shares held for six

 months or less will be treated as a long-term capital loss to the extent of
 any capital gain dividends that were received with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from a Fund or on the value of the shares
 held by you. More tax information is provided in the Additional Statement.
 You should also consult your own tax adviser for information regarding all
 tax consequences applicable to your investments in the Funds.

Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 
 A. General Portfolio Risks
 
 The Funds will be subject to the risks associated with equity securities.
 "Equity securities" include common stocks, preferred stocks, interests in
 real estate investment trusts, convertible debt obligations, convertible
 preferred stocks, equity interests in trusts, partnerships, joint ventures,
 limited liability companies and similar enterprises, warrants and stock pur-
 chase rights. In general, stock values fluctuate in response to the activi-
 ties of individual companies and in response to general market and economic
 conditions. Accordingly, the value of the stocks that a Fund holds may
 decline over short or extended periods. The stock markets tend to be cycli-
 cal, with periods when stock prices generally rise and periods when prices
 generally decline. The volatility of equity securities means that the value
 of your investment in the Funds may increase or decrease. As of the date of
 this Prospectus, certain stock markets were trading at or close to record
 high levels and there can be no guarantee that such levels will continue.
 
 To the extent that a Fund invests in fixed-income securities, that Fund will
 also be subject to the risks associated with its fixed-income securities.
 These risks include interest rate risk, credit risk and call/extension risk.
 In general, interest rate risk involves the risk that when interest rates
 decline, the market value of fixed-income securities tends to increase. Con-
 versely, when interest rates increase, the market value of fixed-income
 securities tends to decline. Credit risk involves the risk that an issuer
 could default on its obligations, and a Fund will not recover its invest-
 ment. Call risk and extension risk are normally present in mortgage-backed
 securities and asset-backed securities. For example, homeowners have the
 option to prepay their mortgages. Therefore, the duration of a security
 backed by home mortgages can either shorten (call risk) or lengthen (exten-
 sion risk). In general, if interest rates on new mortgage loans fall suffi-
 ciently below the interest rates on existing outstanding mortgage loans, the
 rate of prepayment would be expected to increase. Conversely, if mortgage
 loan interest rates rise above the interest rates on existing outstanding
 mortgage loans, the rate of prepayment would be expected to decrease. In
 either case, a change in the prepayment rate can result in losses to invest-
 ors.
 
 The Investment Adviser will not consider the portfolio turnover rate a lim-
 iting factor in making investment decisions for a Fund. A high rate of port-
 folio turnover (100% or more) involves correspondingly greater expenses
 which must be borne by a Fund and its shareholders. The portfolio turnover
 rate is calculated by

<PAGE>
 
                                                                      APPENDIX A
 
 dividing the lesser of the dollar amount of sales or purchases of portfolio
 securities by the average monthly value of a Fund's portfolio securities,
 excluding securities having a maturity at the date of purchase of one year
 or less. See "Financial Highlights" in Appendix B for a statement of the
 Funds' historical portfolio turnover rates.
 
 The following sections provide further information on certain types of secu-
 rities and investment techniques that may be used by the Funds, including
 their associated risks. Additional information is provided in the Additional
 Statement, which is available upon request. Among other things, the Addi-
 tional Statement describes certain fundamental investment restrictions that
 cannot be changed without shareholder approval. You should note, however,
 that all investment objectives and policies not specifically designated as
 fundamental are non-fundamental and may be changed without shareholder
 approval. If there is a change in a Fund's investment objective, you should
 consider whether that Fund remains an appropriate investment in light of
 your then current financial position and needs.
 
 B. Other Portfolio Risks
 
 
 Risks of Investing in Small Capitalization Companies and REITs. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such securities. Small capitalization companies
 and REITs may be thinly traded and may have to be sold at a discount from
 current market prices or in small lots over an extended period of time. In
 addition, these securities are subject to the risk that during certain peri-
 ods the liquidity of particular issuers or industries, or all securities in
 these investment categories, will shrink or disappear suddenly and without
 warning as a result of adverse economic or market conditions, or adverse
 investor perceptions whether or not accurate. Because of the lack of suffi-
 cient market liquidity, a Fund may incur losses because it will be required
 to effect sales at a disadvantageous time and only then at a substantial
 drop in price. Small capitalization companies and REITs include "unseasoned"
 issuers that do not have an established financial history; often have lim-
 ited product lines, markets or financial resources; may depend on or use a
 few key personnel for management; and may be susceptible to losses and risks
 of bankruptcy. Transaction costs for these investments are often higher than
 those of larger capitalization companies. Investments in small capitaliza-
 tion companies and REITs may be more difficult to price precisely than other
 types of securities because of their characteristics and lower trading vol-
 umes.
 
 
                                                                              51
<PAGE>
 
 
 Risks of Foreign Investments. Foreign investments involve special risks that
 are not typically associated with U.S. dollar denominated or quoted securi-
 ties of U.S. issuers. Foreign investments may be affected by changes in cur-
 rency rates, changes in foreign or U.S. laws or restrictions applicable to
 such investments and changes in exchange control regulations (e.g., currency
 blockage). A decline in the exchange rate of the currency (i.e., weakening
 of the currency against the U.S. dollar) in which a portfolio security is
 quoted or denominated relative to the U.S. dollar would reduce the value of
 the portfolio security. In addition, if the currency in which a Fund
 receives dividends, interest or other payments declines in value against the
 U.S. dollar before such income is distributed as dividends to shareholders
 or converted to U.S. dollars, the Fund may have to sell portfolio securities
 to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts after January 1, 1999 that refer to existing currencies
 rather than the euro; the establishment and maintenance of exchange rates
 for currencies being converted into the euro; the fluctuation of the euro
 relative to non-euro currencies during the transition period from January 1,
 1999 to December 31, 2001 and beyond; whether the interest rate, tax and
 labor regimes of European countries participating in the euro will converge
 over time; and whether the conversion of the currencies of other countries
 that now are or may in the future become members of the European Union
 ("EU"), may have an impact on the euro. These or other factors, including
 political and economic risks, could cause market disruptions, and could
 adversely affect the value of securities held by the Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Efforts in foreign countries to remediate potential Year

 2000 problems are not as extensive as those in the United States. As a
 result, the operations of foreign markets, foreign issuers and foreign gov-
 ernments may be disrupted by the Year 2000 Problem, and the investment port-
 folio of a Fund may be adversely affected. Furthermore, with respect to cer-
 tain foreign countries, there is a possibility of nationalization,
 expropriation or confiscatory taxation, imposition of withholding or other
 taxes on dividend or interest payments (or, in some cases, capital gains),
 limitations on the removal of funds or other assets of the Funds, and polit-
 ical or social instability or diplomatic developments which could affect
 investments in those countries.
 
 Concentration of a Fund's assets in one or a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations by certain Funds involves risks not
 present in debt obligations of corporate issuers. The issuer of the debt or
 the governmental authorities that control the repayment of the debt may be
 unable or unwilling to repay principal or interest when due in accordance
 with the terms of such debt, and a Fund may have limited recourse to compel
 payment in the event of a default. Periods of economic uncertainty may
 result in the volatility of market prices of sovereign debt, and in turn a
 Fund's NAV, to a greater extent than the volatility inherent in debt obliga-
 tions of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Funds may also invest in European Depository
 Receipts ("EDRs") or other similar instruments representing securities of
 foreign issuers. ADRs represent the right to receive securities of foreign
 issuers deposited in a domestic bank or a correspondent bank. Prices of ADRs
 are quoted in U.S. dollars, and ADRs are traded in the United States. EDRs
 and GDRs are receipts evidencing an arrangement with a non-U.S. bank. EDRs
 and GDRs are not necessarily quoted in the same currency as the underlying
 security.
 
 Risks of Emerging Countries. Certain Funds may invest in securities of
 issuers located in emerging countries. The risks of foreign investment are
 heightened when the issuer is located in an emerging country. Emerging coun-
 tries are gener-
 
                                                                              53

 ally located in the Asia-Pacific region, Eastern Europe, Latin and South
 America and Africa. A Fund's purchase and sale of portfolio securities in
 certain emerging countries may be constrained by limitations as to daily
 changes in the prices of listed securities, periodic trading or settlement
 volume and/or limitations on aggregate holdings of foreign investors. Such
 limitations may be computed based on the aggregate trading volume by or
 holdings of a Fund, the Investment Adviser, its affiliates and their respec-
 tive clients and other service providers. A Fund may not be able to sell
 securities in circumstances where price, trading or settlement volume limi-
 tations have been reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, it is anticipated that
 a Fund may invest in such countries through other investment funds in such
 countries.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and
 
54
<PAGE>
 
                                                                      APPENDIX A
 
 ethnic, religious and racial disaffection, among other factors, have also
 led to social unrest, violence and/or labor unrest in some emerging coun-
 tries. Unanticipated political or social developments may result in sudden
 and significant investment losses. Investing in emerging countries involves
 greater risk of loss due to expropriation, nationalization, confiscation of
 assets and property or the imposition of restrictions on foreign investments
 and on repatriation of capital invested.
 
 A Fund's investment in emerging countries may also be subject to withholding
 or other taxes, which may be significant and may reduce the return from an
 investment in such country to the Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve a Fund's
 delivery of securities before receipt of payment for their sale. In addi-
 tion, significant delays are common in certain markets in registering the
 transfer of securities. Settlement or registration problems may make it more
 difficult for a Fund to value its portfolio securities and could cause the
 Fund to miss attractive investment opportunities, to have a portion of its
 assets uninvested or to incur losses due to the failure of a counterparty to
 pay for securities the Fund has delivered or the Fund's inability to com-
 plete its contractual obligations. The creditworthiness of the local securi-
 ties firms used by the Fund in emerging countries may not be as sound as the
 creditworthiness of firms used in more developed countries. As a result, the
 Fund may be subject to a greater risk of loss if a securities firm defaults
 in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make a Fund's investments in such countries less liquid and more
 volatile than investments in countries with more developed securities mar-
 kets (such as the United States, Japan and most Western European countries).
 A Fund's investments in emerging countries are subject to the risk that the
 liquidity of a particular investment, or investments generally, in such
 countries will shrink or disappear suddenly and without warning as a result
 of adverse economic, market or political conditions or adverse investor per-
 ceptions, whether or not accurate. Because of the lack of sufficient market
 liquidity, a Fund may incur losses because it will be required to effect
 sales at a disadvantageous time and only then at a substantial drop in
 price. Investments in emerging countries may be more difficult to price pre-
 cisely because of the characteristics discussed above and lower trading vol-
 umes.
 
 A Fund's use of foreign currency management techniques in emerging countries
 may be limited. Due to the limited market for these instruments in emerging
 countries, the Investment Adviser does not currently anticipate that a sig-
 nificant portion of the Funds' currency exposure in emerging countries, if
 any, will be covered by such instruments.
 
                                                                              55
<PAGE>
 
 
 
 Risks of Derivative Investments. A Fund's transactions, if any, in options,
 futures, options on futures, swaps, interest rate caps, floors and collars,
 structured securities and currency transactions involve additional risk of
 loss. Loss can result from a lack of correlation between changes in the
 value of derivative instruments and the portfolio assets (if any) being
 hedged, the potential illiquidity of the markets for derivative instruments,
 or the risks arising from margin requirements and related leverage factors
 associated with such transactions. The use of these management techniques
 also involves the risk of loss if the Investment Adviser is incorrect in its
 expectation of fluctuations in securities prices, interest rates or currency
 prices. Each Fund may also invest in derivative investments for non-hedging
 purposes (that is, to seek to increase total return). Investing for non-
 hedging purposes is considered a speculative practice and presents even
 greater risk of loss.
 
 Risks of Illiquid Securities. Each Fund may invest up to 15% of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of
  more than seven days
 .Certain over-the-counter options
 .Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that such
  restricted security is eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933 ("144A Securities") and, therefore, is liquid
 
 Investing in 144A Securities may decrease the liquidity of a Fund's portfo-
 lio to the extent that qualified institutional buyers become for a time
 uninterested in purchasing these restricted securities. The purchase price
 and subsequent valuation of restricted and illiquid securities normally
 reflect a discount, which may be significant, from the market price of com-
 parable securities for which a liquid market exists.
 
 Credit Risks. Debt securities purchased by the Funds may include securities
 (including zero coupon bonds) issued by the U.S. government (and its agen-
 cies, instrumentalities and sponsored enterprises), foreign governments,
 domestic and foreign corporations, banks and other issuers. Further informa-
 tion is provided in the Additional Statement.
 
 Debt securities rated BBB or higher by Standard & Poor's or Baa or higher by
 Moody's are considered "investment grade." Securities rated BBB or Baa are
 considered medium-grade obligations with speculative characteristics, and
 adverse

                                                                      APPENDIX A
 
 economic conditions or changing circumstances may weaken their issuers'
 capacity to pay interest and repay principal. A security will be deemed to
 have met a rating requirement if it receives the minimum required rating
 from at least one such rating organization even though it has been rated
 below the minimum rating by one or more other rating organizations, or if
 unrated by such rating organizations, determined by the Investment Adviser
 to be of comparable credit quality.
 
 Certain Funds may invest in fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) which are commonly referred to as "junk
 bonds." Junk bonds are considered predominantly speculative and may be ques-
 tionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in a Fund's portfolio is downgraded by a rat-
 ing organization, the market price and liquidity of such security may be
 adversely affected.
 
 Temporary Investment Risks. Each Fund may, for temporary defensive purposes,
 invest a certain percentage of its total assets in:
 .U.S. government securities
 .Commercial paper rated at least A-2 by Standard & Poor's or P-2 by Moody's
 .Certificates of deposit
 .Bankers' acceptances
 .Repurchase agreements
 .Non-convertible preferred stocks and non-convertible corporate bonds with a
  remaining maturity of less than one year
 
 When a Fund's assets are invested in such instruments, the Fund may not be
 achieving its investment objective.
 
 C. Portfolio Securities and Techniques
 
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Funds, including their associ-
 ated risks. Further information is provided in the Additional Statement,
 which is available upon request.
 
 Convertible Securities. Each Fund may invest in convertible securities. Con-
 vertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than non-convertible securities of similar qual-
 ity. Convertible securities in which a Fund invests are subject to the same
 rating criteria as its other investments in
 
                                                                              57

 fixed-income securities. Convertible securities have both equity and fixed-
 income risk characteristics. Like all fixed-income securities, the value of
 convertible securities is susceptible to the risk of market losses attribut-
 able to changes in interest rates. Generally, the market value of convert-
 ible securities tends to decline as interest rates increase and, conversely,
 to increase as interest rates decline. However, when the market price of the
 common stock underlying a convertible security exceeds the conversion price
 of the convertible security, the convertible security tends to reflect the
 market price of the underlying common stock. As the market price of the
 underlying common stock declines, the convertible security, like a fixed-
 income security, tends to trade increasingly on a yield basis, and thus may
 not decline in price to the same extent as the underlying common stock.
 
 Foreign Currency Transactions. A Fund may, to the extent consistent with its
 investment policies, purchase or sell foreign currencies on a cash basis or
 through forward contracts. A forward contract involves an obligation to pur-
 chase or sell a specific currency at a future date at a price set at the
 time of the contract. A Fund may engage in foreign currency transactions for
 hedging purposes and to seek to protect against anticipated changes in
 future foreign currency exchange rates. In addition, certain Funds may also
 enter into such transactions to seek to increase total return, which is con-
 sidered a speculative practice.
 
 Some Funds may also engage in cross-hedging by using forward contracts in a
 currency different from that in which the hedged security is denominated or
 quoted if the Investment Adviser determines that there is a pattern of cor-
 relation between the two currencies. A Fund may hold foreign currency
 received in connection with investments in foreign securities when, in the
 judgment of the Investment Adviser, it would be beneficial to convert such
 currency into U.S. dollars at a later date (e.g., the Investment Adviser may
 anticipate the foreign currency to appreciate against the U.S. dollar).
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, a Fund's NAV to fluctuate (when the
 Fund's NAV fluctuates, the value of your shares may go up or down). Currency
 exchange rates also can be affected unpredictably by the intervention of
 U.S. or foreign governments or central banks, or the failure to intervene,
 or by currency controls or political developments in the United States or
 abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are

                                                                      APPENDIX A
 
 not guaranteed by an exchange or clearinghouse, a default on a contract
 would deprive a Fund of unrealized profits, transaction costs or the bene-
 fits of a currency hedge or could force the Fund to cover its purchase or
 sale commitments, if any, at the current market price.
 
 Structured Securities. Each Fund may invest in structured securities. Struc-
 tured securities are securities whose value is determined by reference to
 changes in the value of specific currencies, interest rates, commodities,
 indices or other financial indicators (the "Reference") or the relative
 change in two or more References. The interest rate or the principal amount
 payable upon maturity or redemption may be increased or decreased depending
 upon changes in the applicable Reference. Structured securities may be posi-
 tively or negatively indexed, so that appreciation of the Reference may pro-
 duce an increase or decrease in the interest rate or value of the security
 at maturity. In addition, changes in the interest rates or the value of the
 security at maturity may be a multiple of changes in the value of the Refer-
 ence. Consequently, structured securities may present a greater degree of
 market risk than other types of fixed-income securities and may be more vol-
 atile, less liquid and more difficult to price accurately than less complex
 securities.
 
 REITs. Each Fund may invest in REITS. REITS are pooled investment vehicles
 that invest primarily in either real estate or real estate related loans.
 The value of a REIT is affected by changes in the value of the properties
 owned by the REIT or securing mortgage loans held by the REIT. REITs are
 dependent upon the ability of the REITs' managers, and are subject to heavy
 cash flow dependency, default by borrowers and the qualification of the
 REITs under applicable regulatory requirements for favorable income tax
 treatment. REITs are also subject to risks generally associated with invest-
 ments in real estate including possible declines in the value of real
 estate, general and local economic conditions, environmental problems and
 changes in interest rates. To the extent that assets underlying a REIT are
 concentrated geographically, by property type or in certain other respects,
 these risks may be heightened. A Fund will indirectly bear its proportionate
 share of any expenses, including management fees, paid by a REIT in which it
 invests.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Fund may write
 (sell) covered call and put options and purchase put and call options on any
 securities in which they may invest or on any securities index comprised of
 securities in which they may invest. A Fund may
 
                                                                              59
<PAGE>
 
 
 also, to the extent that it invests in foreign securities, purchase and sell
 (write) put and call options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of the Investment Adviser to manage future price fluctu-
 ations and the degree of correlation between the options and securities (or
 currency) markets. If the Investment Adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in a Fund's investment portfolio, the Fund may incur losses that
 it would not otherwise incur. The use of options can also increase a Fund's
 transaction costs. Options written or purchased by the Funds may be traded
 on either U.S. or foreign exchanges or over-the-counter. Foreign and over-
 the-counter options will present greater possibility of loss because of
 their greater illiquidity and credit risks.
 
 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 government securities), foreign currencies, securities indices and other
 financial instruments and indices. The Funds may engage in futures transac-
 tions on both U.S. and foreign exchanges.
 
 Each Fund may purchase and sell futures contracts, and purchase and write
 call and put options on futures contracts, in order to seek to increase
 total return or to hedge against changes in interest rates, securities
 prices or, to the extent a Fund invests in foreign securities, currency
 exchange rates, or to otherwise manage their term structures, sector selec-
 tion and durations in accordance with their investment objectives and poli-
 cies. Each Fund may also enter into closing purchase and sale transactions
 with respect to such contracts and options. A Fund will engage in futures
 and related options transactions for bona fide hedging purposes as defined
 in regulations of the Commodity Futures Trading Commission or to seek to
 increase total return to the extent permitted by such regulations. A Fund
 may not purchase or sell futures contracts or purchase or sell related
 options to seek to increase total return, except for closing purchase or
 sale transactions, if immediately thereafter the sum of the amount of ini-
 tial margin deposits and premiums paid on the Fund's outstanding positions
 in futures and related options entered

                                                                      APPENDIX A
 
 into for the purpose of seeking to increase total return would exceed 5% of
 the market value of the Fund's net assets.
 
 Futures contracts and related options present the following risks:
 .While a Fund may benefit from the use of futures and options on futures,
  unanticipated changes in interest rates, securities prices or currency
  exchange rates may result in poorer overall performance than if the Fund
  had not entered into any futures contracts or options transactions.
 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and a Fund may be exposed to additional risk
  of loss.
 .The loss incurred by a Fund in entering into futures contracts and in writ-
  ing call options on futures is potentially unlimited and may exceed the
  amount of the premium received.
 .Futures markets are highly volatile and the use of futures may increase the
  volatility of a Fund's NAV.
 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to a Fund.
 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.
 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 Equity Swaps. Each Fund may invest in equity swaps. Equity swaps allow the
 parties to a swap agreement to exchange the dividend income or other compo-
 nents of return on an equity investment (for example, a group of equity
 securities or an index) for a component of return on another non-equity or
 equity investment.
 
 An equity swap may be used by a Fund to invest in a market without owning or
 taking physical custody of securities in circumstances in which direct
 investment may be restricted for legal reasons or is otherwise impractical.
 Equity swaps are derivatives and their value can be very volatile. To the
 extent that the Investment Adviser does not accurately analyze and predict
 the potential relative fluctuation of the components swapped with another
 party, a Fund may suffer a loss. The value of some components of an equity
 swap (such as the dividends on a common stock) may also be sensitive to
 changes in interest rates. Furthermore, a Fund may suffer a loss if the
 counterparty defaults.
 
 When-Issued Securities and Forward Commitments. Each Fund may invest in
 when-issued securities. When-issued securities are securities that have been
 authorized, but not yet issued. When-issued securities are purchased in
 order to secure what is considered to be an advantageous price and yield to
 the Fund at the time of entering into the transaction. A forward commitment
 involves the entering into
 
                                                                              61
<PAGE>
 
 
 a contract to purchase or sell securities for a fixed price at a future date
 beyond the customary settlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although a Fund will generally
 purchase securities on a when-issued or forward commitment basis with the
 intention of acquiring securities for its portfolio, a Fund may dispose of
 when-issued securities or forward commitments prior to settlement if the
 Investment Adviser deems it appropriate.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Fund may enter into repurchase agreements
 with primary dealers in U.S. government securities and member banks of the
 Federal Reserve System which furnish collateral at least equal in value or
 market price to the amount of their repurchase obligation.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund are less than the repurchase price and the
 Fund's costs associated with delay and enforcement of the repurchase agree-
 ment. In addition, in the event of bankruptcy of the seller, a Fund could
 suffer additional losses if a court determines that the Fund's interest in
 the collateral is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Certain
 Funds, together with other registered investment companies having advisory
 agreements with the Investment Adviser or any of its affiliates, may trans-
 fer uninvested cash balances into a single joint account, the daily aggre-
 gate balance of which will be invested in one or more repurchase agreements.
 
 Lending of Portfolio Securities. Each Fund may engage in securities lending.
 Securities lending involves the lending of securities owned by a Fund to
 financial institutions such as certain broker-dealers. The borrowers are
 required to secure their loan continuously with cash, cash equivalents, U.S.
 government securities or letters of credit in an amount at least equal to
 the market value of the securities loaned. Cash collateral may be invested
 in cash equivalents. If the Investment Adviser determines to make securities
 loans, the value of the securities loaned may not exceed 33 1/3% of the
 value of the total assets of a Fund (including the loan collateral).

 A Fund may lend its securities to increase its income. A Fund may, however,
 experience delay in the recovery of its securities if the institution with
 which it has engaged in a portfolio loan transaction breaches its agreement
 with the Fund.
 
 Short Sales Against-the-Box. Certain Funds may make short sales against-the-
 box. A short sale against-the-box means that at all times when a short posi-
 tion is open the Fund will own an equal amount of securities sold short, or
 securities convertible into or exchangeable for, without payment of any fur-
 ther consideration, an equal amount of the securities of the same issuer as
 the securities sold short.
 
 Preferred Stock, Warrants and Rights. Each Fund may invest in preferred
 stock, warrants and rights. Preferred stocks are securities that represent
 an ownership interest providing the holder with claims on the issuer's earn-
 ings and assets before common stock owners but after bond owners. Unlike
 debt securities, the obligations of an issuer of preferred stock, including
 dividend and other payment obligations, may not typically be accelerated by
 the holders of such preferred stock on the occurrence of an event of default
 or other non-compliance by the issuer of the preferred stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.
 
 Other Investment Companies. Each Fund may invest in securities of other
 investment companies (including SPDRs and WEBs, as defined below) subject to
 statutory limitations prescribed by the Investment Company Act. These limi-
 tations include a prohibition on any Fund acquiring more than 3% of the vot-
 ing shares of any other investment company, and a prohibition on investing
 more than 5% of a Fund's total assets in securities of any one investment
 company or more than 10% of its total assets in securities of all investment
 companies. A Fund will indirectly bear its proportionate share of any man-
 agement fees and other expenses paid by such other investment companies.
 Such other investment companies will have investment objectives, policies
 and restrictions substantially similar to those of the acquiring Fund and
 will be subject to substantially the same risks.
 
 .Standard & Poor's Depository Receipts. The Funds may, consistent with their
  investment policies, purchase Standard & Poor's Depository Receipts
  ("SPDRs"). SPDRs are securities traded on the American Stock Exchange
  ("AMEX") that represent ownership in the SPDR Trust, a trust which has been
  established to accumulate and hold a portfolio of common stocks that is
  intended to track the price performance and dividend yield of the S&P 500.
  The SPDR Trust is sponsored by a subsidiary of the AMEX. SPDRs may be used
  for several reasons, including, but not limited to, facilitating the han-
  dling of
 
                                                                              63
<PAGE>
 
 
  cash flows or trading, or reducing transaction costs. The price movement of
  SPDRs may not perfectly parallel the price action of the S&P 500.
 
 .World Equity Benchmark Shares. World Equity Benchmark Shares ("WEBS") are
  shares of an investment company that invests substantially all of its
  assets in securities included in the MSCI indices for specified countries.
  WEBS are listed on the AMEX and were initially offered to the public in
  1996. The market prices of WEBS are expected to fluctuate in accordance
  with both changes in the NAVs of their underlying indices and supply and
  demand of WEBS on the AMEX. To date, WEBS have traded at relatively modest
  discounts and premiums to their NAVs. However, WEBS have a limited operat-
  ing history and information is lacking regarding the actual performance and
  trading liquidity of WEBS for extended periods or over complete market
  cycles. In addition, there is no assurance that the requirements of the
  AMEX necessary to maintain the listing of WEBS will continue to be met or
  will remain unchanged. In the event substantial market or other disruptions
  affecting WEBS should occur in the future, the liquidity and value of a
  Fund's shares could also be substantially and adversely affected. If such
  disruptions were to occur, a Fund could be required to reconsider the use
  of WEBS as part of its investment strategy.
 
 Unseasoned Companies. Each Fund may invest in companies (including predeces-
 sors) which have operated less than three years, except that this limitation
 does not apply to debt securities which have been rated investment grade or
 better by at least one NRSRO. The securities of such companies may have lim-
 ited liquidity, which can result in their being priced higher or lower than
 might otherwise be the case. In addition, investments in unseasoned compa-
 nies are more speculative and entail greater risk than do investments in
 companies with an established operating record.
 
 Corporate Debt Obligations. Corporate debt obligations include bonds, notes,
 debentures and other obligations of corporations to pay interest and repay
 principal, and include securities issued by banks and other financial insti-
 tutions. Each Fund may invest in corporate debt obligations issued by U.S.
 and certain non-U.S. issuers which issue securities denominated in the U.S.
 dollar (including Yankee and Euro obligations). In addition to obligations
 of corporations, corporate debt obligations include securities issued by
 banks and other financial institutions and supranational entities (i.e., the
 World Bank, the International Monetary Fund, etc.).
 
 Bank Obligations. Each Fund may invest in obligations issued or guaranteed
 by U.S. or foreign banks. Bank obligations, including without limitations,
 time deposits, bankers' acceptances and certificates of deposit, may be gen-
 eral obligations of the parent bank or may be limited to the issuing branch
 by the terms of the specific obligations or by government regulations. Banks
 are subject to extensive but

                                                                      APPENDIX A
 
 different governmental regulations which may limit both the amount and types
 of loans which may be made and interest rates which may be charged. In addi-
 tion, the profitability of the banking industry is largely dependent upon
 the availability and cost of funds for the purpose of financing lending
 operations under prevailing money market conditions. General economic condi-
 tions as well as exposure to credit losses arising from possible financial
 difficulties of borrowers play an important part in the operation of this
 industry.
 
 U.S. Government Securities and Related Custodial Receipts. Each Fund may
 invest in U.S. government securities and related custodial receipts. U.S.
 government securities include U.S. Treasury obligations and obligations
 issued or guaranteed by U.S. government agencies, instrumentalities or spon-
 sored enterprises. U.S. government securities may be supported by (a) the
 full faith and credit of the U.S. Treasury (such as the Government National
 Mortgage Association ("Ginnie Mae")); (b) the right of the issuer to borrow
 from the U.S. Treasury (such as securities of the Student Loan Marketing
 Association); (c) the discretionary authority of the U.S. government to pur-
 chase certain obligations of the issuer (such as the Federal National Mort-
 gage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation
 ("Freddie Mac")); or (d) only the credit of the issuer. U.S. government
 securities also include Treasury receipts, zero coupon bonds and other
 stripped U.S. government securities, where the interest and principal compo-
 nents of stripped U.S. government securities are traded independently.
 
 Interests in U.S. government securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S.
 government.
 
 Mortgage-Backed Securities. Certain Funds may invest in mortgage-backed
 securities. Mortgage-backed securities represent direct or indirect partici-
 pations in, or are collateralized by and payable from, mortgage loans
 secured by real property. Mortgage-backed securities can be backed by either
 fixed rate mortgage loans or adjustable rate mortgage loans, and may be
 issued by either a governmental or non-governmental entity. Privately issued
 mortgage-backed securities are normally structured with one or more types of
 "credit enhancement." However, these mortgage-backed securities typically do
 not have the same credit standing as U.S. government guaranteed mortgage-
 backed securities.
 
 Mortgage-backed securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs") and Real Estate Mortgage
 Investment Conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an
 
                                                                              65
<PAGE>
 
 
 investor with a specified interest in the cash flow from a pool of under-
 lying mortgages or of other mortgage-backed securities. CMOs are issued in
 multiple classes. In most cases, payments of principal are applied to the
 CMO classes in the order of their respective stated maturities, so that no
 principal payments will be made on a CMO class until all other classes hav-
 ing an earlier stated maturity date are paid in full. A REMIC is a CMO that
 qualifies for special tax treatment and invests in certain mortgages princi-
 pally secured by interests in real property and other permitted investments.
 
 Mortgaged-backed securities also include stripped mortgage-backed securities
 ("SMBS"), which are derivative multiple class mortgage-backed securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other mortgage-backed securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 Asset-Backed Securities. Certain Funds may invest in asset-backed securi-
 ties. Asset-backed securities are securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed securities are often subject to more rapid repayment than their
 stated maturity date would indicate as a result of the pass-through of pre-
 payments of principal on the underlying loans. During periods of declining
 interest rates, prepayment of loans underlying asset-backed securities can
 be expected to accelerate. Accordingly, a Fund's ability to maintain posi-
 tions in such securities will be affected by reductions in the principal
 amount of such securities resulting from prepayments, and its ability to
 reinvest the returns of principal at comparable yields is subject to gener-
 ally prevailing interest rates at that time. Asset-backed securities present
 credit risks that are not presented by mortgage-backed securities. This is
 because asset-backed securities generally do not have the benefit of a secu-
 rity interest in collateral that is comparable to mortgage assets. There is
 the possibility that, in some cases, recoveries on repossessed collateral
 may not be available to support payments on these securities. In the event
 of a default, a Fund may suffer a loss if it cannot sell collateral quickly
 and receive the amount it is owed.
 
 Borrowings. Each Fund can borrow money from banks and other financial insti-
 tutions in amounts not exceeding one-third of their total assets for tempo-
 rary or emergency purposes. A Fund may not make additional investments if
 borrowings exceed 5% of its total assets.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

Prior Performance of Similarly Advised Accounts of the Investment Adviser
 
 
 EUROPEAN EQUITY FUND
 
 The following table sets forth the Investment Adviser's composite perfor-
 mance data relating to the historical performance of all discretionary pri-
 vate accounts managed by the Investment Adviser that have investment objec-
 tives, policies and strategies substantially similar to the European Equity
 Fund. The information is provided to illustrate the past performance of the
 Investment Adviser in managing substantially similar accounts as measured
 against the FT/S&P Actuaries Europe Index (unhedged) and does not represent
 the performance of the European Equity Fund. Investors should not consider
 this performance data as a substitute for the performance of the European
 Equity Fund nor should investors consider this data as an indication of
 future performance of the European Equity Fund or of the Investment Adviser.
 The FT/S&P Actuaries Europe Index (unhedged) is unmanaged and investors can-
 not invest directly in the Index.

 In accordance with the standards of the Association for Investment Manage-

 information was calculated on a time-weighted and asset-weighted total
 return

<PAGE>
 
                                                                      APPENDIX C
 
basis which includes realized and unrealized gains and losses plus income. The
composite performance is net of applicable investment management fees, broker-
age commissions, execution costs and custodial fees, without provision for fed-
eral and state taxes, if any. Total return performance of the European Equity
Fund will be calculated in accordance with the regulations of the SEC. The SEC
standardized average annual total return is neither time-weighted nor asset-
weighted and is determined for specified periods by computing the annualized
percentage change in the value of an initial amount that is invested in a share
class of the Fund at the maximum public offering price. Investors should be
aware that the differences in methodology between AIMR and SEC requirements
could result in different performance data for identical time periods.
 
All returns presented reflect the reinvestment of dividends and other earnings.
The weighted-average expenses of the private accounts used in calculating the
Investment Adviser's net composite performance data were 0.46% annualized,
which are lower than the estimated expenses of Service Shares of the European
Equity Fund stated under "Fund Fees and Expenses" above. The performance of the
private accounts would have been lower 8if they had been subject to the
expenses of the European Equity Fund. In addition, the private accounts are not
subject to the same diversification requirements, specific tax restrictions and
investment limitations imposed on the European Equity Fund by the Act and
Subchapter M of the Code. Consequently, the performance results of the Invest-
ment Adviser's composite could have been adversely affected if the private
accounts had been regulated as investment companies under the federal securi-
ties laws.

General Investment
Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser (the "Investment
 Adviser") to five asset allocation portfolios: the Conservative Strategy
 Portfolio, Balanced Strategy Portfolio (formerly, the Income Strategy Port-
 folio), Growth and Income Strategy Portfolio, Growth Strategy Portfolio and
 Aggressive Growth Strategy Portfolio (referred to as the "Portfolios" or the
 "Funds" interchangeably herein). The Portfolios are intended for investors
 who prefer to have their asset allocation decisions made by professional
 money managers. Each Portfolio seeks to achieve its objectives by investing
 in a combination of underlying funds for which Goldman Sachs now or in the
 future acts as investment adviser or principal underwriter (the "Underlying
 Funds"). Some of these Underlying Funds invest primarily in fixed-income or
 money market securities (the "Underlying Fixed-Income Funds") and other
 Underlying Funds invest primarily in equity securities (the "Underlying
 Equity Funds"). An investor may choose to invest in one or more of the Port-
 folios based on individual investment goals, risk tolerance, and financial
 circumstances.
 
 The investment objectives and policies of the Portfolios are similar to the
 investment objectives and policies of other mutual funds that the Investment
 Adviser manages. Although the objectives and policies may be similar, the
 investment results of the Portfolios may be higher or lower than the results
 of such other mutual funds. The Investment Adviser cannot guarantee, and
 makes no representation, that the investment results of similar funds will
 be comparable even though the funds have the same Investment Adviser.
 
 Goldman Sachs' Asset Allocation Investment Philosophy:
 The Investment Adviser's Quantitative Research Group uses disciplined quan-
 titative models to determine the relative attractiveness of the world's
 stock, bond and currency markets. These models use financial and economic
 variables to capture fundamental relationships that the Quantitative
 Research Group believes make sense. While the Investment Adviser's process
 is rigorous and quantitative, it also incorporates clear economic reasoning
 behind each recommendation.
 
 The Asset Allocation Investment Process involves investing a Portfolio's
 assets in other Goldman Sachs Funds within specified equity and fixed-income
 percentage ranges.

                                                                               1
<PAGE>
 
 
 Each Portfolio starts with a strategic allocation among the various asset
 classes. The Investment Adviser then tactically deviates from the strategic
 allocations based on forecasts provided by the models. The tactical process
 seeks to add value by overweighting attractive markets and underweighting
 unattractive markets. Greater deviations from the strategic allocation of a
 given Portfolio result in higher risk that the tactical allocation will
 underperform the strategic allocation. However, the Investment Adviser's
 risk control process balances the amount any asset class can be overweighted
 in seeking to achieve higher expected returns against the amount of risk
 imposed by that deviation from the strategic allocation. The Investment
 Adviser employs Goldman Sachs' proprietary Black-Litterman asset allocation
 technique in an effort to optimally balance these two goals.

Portfolio Investment Objectives and Strategies
 
 Goldman Sachs Conservative Strategy Portfolio
 
   PORTFOLIO FACTS
- --------------------------------------------------------------------------------
 
        Objective:  Current income, consistent with the preservation of capi-
                    tal and secondarily the potential for capital appreciation
 
 Investment Focus:  Primarily domestic fixed-income funds (approximately 80%)
                    focusing on short-term investments and money market funds,
                    with the balance in domestic stock funds and a small allo-
                    cation to a global bond fund
 
 Investment Style:  Asset Allocation
 
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income, consistent with the preservation of cap-
 ital and secondarily also considers the potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 80% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds, with a focus on
 short-term investments including money market funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its assets in
 the Global Income Fund, Financial Square Prime Obligations Fund and CORE
 Large Cap Value Fund. It is expected that the Portfolio will invest more
 than 25% of its assets in the Short Duration Government Fund. The Portfolio
 may not invest in Underlying Equity Funds that invest principally in foreign
 equity securities.

The Investment Adviser will invest in particular Underlying Funds based on var-
ious criteria. Among other things, the Investment Adviser will analyze the
Underlying Funds' respective investment objectives, policies and investment
strategies in order to determine which Underlying Funds, in combination with
other Underlying Funds, are appropriate in light of a Portfolio's investment
objective.
 
Each Portfolio's turnover rate is expected not to exceed 50% annually. A Port-
folio may purchase or sell securities to: (a) accommodate purchases and sales
of its shares; (b) change the percentages of its assets invested in each of the
Underlying Funds in response to economic or market conditions; and (c) maintain
or modify the allocation of its assets among the Underlying Funds within the
percentage ranges described above.

                                                 PRINCIPAL INVESTMENT STRATEGIES
 
 
 While each Portfolio can invest in any or all of the Underlying Funds, it is
 expected that each Portfolio will normally invest in only some of the Under-
 lying Funds at any particular time. Each Portfolio's investment in any of
 the Underlying Funds may, and in some cases is expected to, exceed 25% of
 such Portfolio's total assets.
 
 THE PARTICULAR UNDERLYING FUNDS IN WHICH EACH PORTFOLIO MAY INVEST, THE
 EQUITY/FIXED-INCOME TARGETS AND RANGES AND THE INVESTMENTS IN EACH UNDER-
 LYING FUND MAY BE CHANGED FROM TIME TO TIME WITHOUT SHAREHOLDER APPROVAL.
 
 In addition, each Portfolio's investment objectives and all policies not
 specifically designated as fundamental in this Prospectus or the Statement
 of Additional Information (the "Additional Statement") are non-fundamental
 and may be changed without shareholder approval. If there is a change in a
 Portfolio's investment objective, you should consider whether that Portfolio
 remains an appropriate investment in light of your then current financial
 position and needs.

Principal Risks of the Portfolios
 
Loss of money is a risk of investing in each Portfolio. An investment in a
Portfolio is not a deposit of any bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other governmental agency. While
the Portfolios offer a greater level of diversification than many other types
of mutual funds, a single Portfolio may not provide a complete investment pro-
gram for an investor. The following summarizes important risks that apply to
the Portfolios and may result in a loss of your investment. There can be no
assurance that a Portfolio will achieve its investment objective.
 
 .Investing in the Underlying Funds--The investments of each Portfolio are
 concentrated in the Underlying Funds, and each Portfolio's investment
 performance is directly related to the investment performance of the
 Underlying Funds held by it. The ability of each Portfolio to meet its
 investment objective is directly related to the ability of the Underlying
 Funds to meet their objectives as well as the allocation among those
 Underlying Funds by the Investment Adviser. The value of the Underlying Funds'
 investments, and the net asset values ("NAV") of the shares of both the
 Portfolios and the Underlying Funds, will fluctuate in response to various
 market and economic factors related to the equity and fixed-income markets, as
 well as the financial condition and prospects of issuers in which the
 Underlying Funds invest. There can be no assurance that the investment
 objective of any Portfolio or any Underlying Fund will be achieved.
 .Investments of the Underlying Funds--Because the Portfolios invest in the
 Underlying Funds, the Portfolios' shareholders will be affected by the
 investment policies of the Underlying Funds in direct proportion to the amount
 of assets the Portfolios allocate to those Funds. Each Portfolio may invest in
 Underlying Funds that in turn invest in small capitalization companies and
 foreign issuers and thus are subject to additional risks, including changes in
 foreign currency exchange rates and political risk. Foreign investments may
 include securities of issuers located in emerging countries in Asia, Latin
 America, Eastern Europe and Africa. Each Portfolio may also invest in
 Underlying Funds that in turn invest in non-investment grade fixed-income
 securities ("junk bonds"), which are considered speculative by traditional
 standards. In addition, the Underlying Funds may purchase derivative
 securities; enter into forward currency transactions; lend their portfolio
 securities; enter into futures contracts and options transactions; purchase
 zero coupon bonds and payment-in-kind bonds; purchase securities issued by
 real estate investment trusts ("REITs") and other issuers in the real estate
 industry; purchase restricted and illiquid securities; purchase securities on
 a when-issued or delayed delivery basis; enter into repurchase agreements;
 borrow money; and

                                               PRINCIPAL RISKS OF THE PORTFOLIOS
 
 engage in various other investment practices. The risks presented by these
 investment practices are discussed in Appendix A to this Prospectus and the
 Additional Statement.
 .Affiliated Persons--In managing the Portfolios, the Investment Adviser will
 have the authority to select and substitute Underlying Funds. The Investment
 Adviser is subject to conflicts of interest in allocating Portfolio assets
 among the various Underlying Funds both because the fees payable to it and/or
 its affiliates by some Underlying Funds are higher than the fees payable by
 other Underlying Funds and because the Investment Adviser and its affiliates
 are also responsible for managing the Underlying Funds. The Trustees and
 officers of the Goldman Sachs Trust may also have conflicting interests in
 fulfilling their fiduciary duties to both the Portfolios and the Underlying
 Funds.
 .Expenses--You may invest in the Underlying Funds directly. By investing in the
 Underlying Funds indirectly through a Portfolio, you will incur not only a
 proportionate share of the expenses of the Underlying Funds held by the
 Portfolio (including operating costs and investment management fees), but also
 expenses of the Portfolio.
 .Temporary Investments--Although the Portfolios normally seek to remain
 substantially invested in the Underlying Funds, each Portfolio may invest a
 portion of its assets in high-quality, short-term debt obligations (including
 commercial paper, certificates of deposit, bankers' acceptances, repurchase
 agreements, debt obligations backed by the full faith and credit of the U.S.
 government and demand and time deposits of domestic and foreign banks and
 savings and loan associations) to maintain liquidity, to meet shareholder
 redemptions and for other short-term cash needs. Also, there may be times
 when, in the opinion of the Investment Adviser, abnormal market or economic
 conditions warrant that, for temporary defensive purposes, a Portfolio may
 invest without limitation in short-term obligations. When a Portfolio's assets
 are invested in such investments, the Portfolio may not be achieving its
 investment objective.
 .Other Risks--Each Portfolio is subject to other risks, such as (1) the risk
 that the operations of a Portfolio and the Underlying Funds in which it
 invests, or the value of their securities, will be disrupted by the "Year 2000
 Problem;" (2) the risk that a Portfolio will not be able to pay redemption
 proceeds within the period stated in this Prospectus because of unusual market
 conditions, an unusually high volume of redemption requests or other reasons
 (Liquidity Risk); or (3) the risk that a strategy used by the Investment
 Adviser may fail to produce the intended results (Management Risk).

Principal Risks of the Underlying Funds
 
The following summarizes important risks that apply to the Underlying Funds and
may result in a loss of your investment in a Portfolio. There can be no assur-
ance that an Underlying Fund will achieve its investment objective.
Risks That Apply To All Underlying Funds:
 .Interest Rate Risk--The risk that when interest rates increase, fixed-income
 securities held by an Underlying Fund will decline in value. Long-term fixed-
 income securities will normally have more price volatility because of this
 risk than short-term securities.
 .Credit/Default Risk--The risk that an issuer of fixed-income securities held
 by an Underlying Fund (which may have low credit ratings) may default on its
 obligation to pay interest and repay principal.
 .Market Risk--The risk that the value of the securities in which an Underlying
 Fund invests may go up or down in response to the prospects of individual com-
 panies and/or general economic conditions. Price changes may be temporary or
 last for extended periods.
 .Derivatives Risk--The risk that loss may result from an Underlying Fund's
 investments in options, futures, swaps, structured securities and other deriv-
 ative instruments. These instruments may be leveraged so that small changes
 may produce disproportionate losses to an Underlying Fund.
 .Foreign Risk--The risk that when an Underlying Fund invests in foreign securi-
 ties, it will be subject to the risks of loss not typically associated with
 domestic issuers. Loss may result because of less foreign government regula-
 tion, less public information and less economic, political and social stabili-
 ty. Loss may also result from the imposition of exchange controls, confisca-
 tions and other government restrictions. The Underlying Funds will also be
 subject to the risk of negative foreign currency rate fluctuations. Foreign
 risks will normally be greatest when an Underlying Fund invests in issuers
 located in emerging countries.
 .Management Risk--The risk that a strategy used by an investment adviser to the
 Underlying Funds may fail to produce the intended results.
 .Liquidity Risk--The risk that an Underlying Fund will not be able to pay
 redemption proceeds within the time period stated in this Prospectus, because
 of unusual market conditions, an unusually high volume of redemption requests,
 or other reasons. Underlying Funds that invest in non-investment grade fixed-
 income securities, small capitalization stocks, REITs or emerging country
 issuers will be especially subject to the risk that during certain periods the
 liquidity of particular issuers or industries, or all securities within these
 investment categories, will shrink or disappear suddenly and without warning
 as a result of adverse economic, market or political events, or adverse
 investor perceptions whether or not accurate.
 .Other Risks--Each Underlying Fund is subject to other risks, such as the risk
 that its operations, or the value of its portfolio securities, will be dis-
 rupted by the "Year 2000 Problem."

                                         PRINCIPAL RISKS OF THE UNDERLYING FUNDS
 
 
Risks That Apply Primarily To The Underlying Fixed-Income Funds:
 
 .Call Risk--The risk that an issuer will exercise its right to pay principal on
 an obligation held by an Underlying Fund (such as a Mortgage-Backed Security)
 earlier than expected. This may happen when there is a decline in interest
 rates. Under these circumstances, an Underlying Fund may be unable to recoup
 all of its initial investment and will also suffer from having to reinvest in
 lower yielding securities.
 .Extension Risk--The risk that an issuer will exercise its right to pay princi-
 pal on an obligation held by an Underlying Fund (such as a Mortgage-Backed
 Security) later than expected. This may happen when there is a rise in inter-
 est rates. Under these circumstances, the value of an obligation will
 decrease, and an Underlying Fund will also suffer from the inability to invest
 in higher yielding securities.
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risk That Applies Primarily To The Underlying Equity Funds:
 
 .Stock Risk--The risk that stock prices have historically risen and fallen in
 periodic cycles. As of the date of this Prospectus, U.S. stock markets and
 certain foreign stock markets were trading at or close to record high levels.
 There is no guarantee that such levels will continue.
 
Risks That Are Particularly Important For Specific Underlying Funds:
 
 .Country Risk--The European Equity Fund invests primarily in equity securities
 of European companies. The Japanese Equity Fund invests primarily in equity
 securities of Japanese companies. The Asia Growth Fund invests primarily in
 equity securities of Asian issuers. The Global Income Fund is non-diversified.
 The Global Income Fund may invest more than 25% of its total assets in the
 securities of corporate and governmental issuers located in each of Canada,
 Germany, Japan, and the United Kingdom as well as in the securities of U.S.
 
                                                                              19

 issuers. Concentration of the investments of these or other Underlying Funds
 in issuers located in a particular country or region will subject the Under-
 lying Fund, to a greater extent than if investments were less concentrated, to
 losses arising from adverse developments affecting those issuers or countries.
 .Emerging Countries Risk--Certain Underlying Funds invest in emerging country
 securities. The securities markets of Asian, Latin American, Eastern European,
 African and other emerging countries are less liquid, are especially subject
 to greater price volatility, have smaller market capitalizations, have less
 government regulation and are not subject to as extensive and frequent
 accounting, financial and other reporting requirements as the securities mar-
 kets of more developed countries. Further, investment in equity securities of
 issuers located in Russia and certain other emerging countries involves risk
 of loss resulting from problems in share registration and custody and substan-
 tial economic and political disruptions. These risks are not normally associ-
 ated with investments in more developed countries.
 .Small Cap Stock and REIT Risks--Certain Underlying Funds invest in small cap
 stocks and REITs. The securities of small capitalization companies and REITs
 involve greater risks than those associated with larger, more established com-
 panies and may be subject to more abrupt or erratic price movements. Securi-
 ties of such issuers may lack sufficient market liquidity to enable an Under-
 lying Fund to effect sales at an advantageous time or without a substantial
 drop in price.
 ."Junk Bond" Risk--Certain Underlying Funds invest in non-investment grade
 fixed-income securities (commonly known as "junk bonds") that are considered
 predominantly speculative by traditional investment standards. Non-investment
 grade fixed-income securities and unrated securities of comparable credit
 quality are subject to the increased risk of an issuer's inability to meet
 principal and interest obligations. These securities may be subject to greater
 price volatility due to such factors as specific corporate developments,
 interest rate sensitivity, negative perceptions of the junk bond markets gen-
 erally and less secondary market liquidity.
 
More information about the portfolio securities and investment techniques of
the Underlying Funds, and their associated risks, is provided in Appendix A.
You should consider the investment risks discussed in this section and in
Appendix A. Both are important to your investment choice.

Portfolio Performance
 
 HOW THE PORTFOLIOS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Portfolio by showing: (a) changes in the performance of a Portfo-
 lio's Class A Shares from year to year; and (b) how the average annual
 returns of a Portfolio's Class A, B and C Shares compare to those of broad-
 based securities market indices. The bar chart and table assume reinvestment
 of dividends and distributions. A Portfolio's past performance is not neces-
 sarily an indication of how the Portfolio will perform in the future. The
 average annual total return calculation reflects a maximum initial sales
 charge of 5.5% for Class A Shares, the assumed contingent deferred sales
 charge ("CDSC") for Class B Shares (5% maximum declining to 0% after six
 years), and the assumed CDSC for Class C Shares (1% if redeemed within 12
 months of purchase). The bar chart does not reflect the sales loads applica-
 ble to Class A Shares. If the sales loads were reflected, returns would be
 less. Performance reflects expense limitations in effect. If expense limita-
 tions were not in place, a Portfolio's performance would have been reduced.
 The Conservative Strategy Portfolio did not commence operations until Febru-
 ary 8, 1999. Since the Portfolio has less than one calendar year's perfor-
 mance, no performance information is provided in this section.

                                                     PORTFOLIO FEES AND EXPENSES
 
 
/1/The maximum sales charge is a percentage of the offering price. A CDSC of 1%
is imposed on certain redemptions (within 18 months of purchase) of Class A
Shares sold without an initial sales charge as part of an investment of $1 mil-
lion or more.
/2/The maximum CDSC is a percentage of the lesser of the net asset value
("NAV") at the time of the redemption or the NAV when the shares were origi-
nally purchased.
/3/A CDSC is imposed upon Class B Shares redeemed within six years of purchase
at a rate of 5% in the first year, declining to 1% in the sixth year, and elim-
inated thereafter.
/4/A CDSC of 1% is imposed on Class C Shares redeemed within 12 months of pur-
chase.
/5/A transaction fee of $7.50 may be charged for redemption proceeds paid by
wire. In addition to free reinvestments of dividends and distributions in
shares of other Goldman Sachs Funds or shares of the Goldman Sachs Institu-
tional Liquid Assets Portfolios (the "ILA Portfolios") and free automatic
exchanges pursuant to the Automatic Exchange Program, six free exchanges are
permitted in each 12-month period. A fee of $12.50 may be charged for each sub-
sequent exchange during such period.
/6/The Portfolios' annual operating expenses have been restated to reflect cur-
rent fees, except for the Conservative Strategy Portfolio, whose expenses are
estimated for the current fiscal year. "Underlying Fund Expenses" for each
Portfolio are based upon the strategic allocation of each Portfolio's invest-
ment in the Underlying Funds and upon the actual total operating expenses of
the Underlying Funds (including any current waivers and expense limitations of
the Underlying Funds). Actual Underlying Fund Expenses incurred by each Portfo-
lio may vary with changes in the allocation of each Portfolio's assets among
the Underlying Funds and with other events that directly affect the expenses of
the Underlying Funds.
/7/The Investment Adviser has voluntarily agreed not to impose a portion of the
management fee on the Portfolios equal to 0.20% of the Portfolios' average
daily net assets. As a result of fee waivers, current management fees of the
Portfolios are 0.15% of each Portfolio's average daily net assets. The waivers
may be terminated at any time at the option of the Investment Adviser.
/8/"Other Expenses" include transfer agency fees equal to 0.19% of the average
daily net assets of each Portfolio's Class A, B and C Shares, plus all other
ordinary expenses not detailed above. The Investment Adviser has voluntarily
agreed to reduce or limit "Other Expenses" (excluding management fees, distri-
bution and service fees, transfer agency fees, taxes, interest and brokerage
fees and litigation, indemnification and other extraordinary expenses) to 0.00%
of each Portfolio's average daily net assets.

Example
 
The following Example is intended to help you compare the cost of investing in
a Portfolio (without waivers and expense limitations) with the cost of invest-
ing in other mutual funds. The Example assumes that you invest $10,000 in Class
A, B or C Shares of a Portfolio for the time periods indicated and then redeem
all of your shares at the end of those periods. The Example also assumes that
your investment has a 5% return each year and that a Portfolio's operating
expenses remain the same. Although your actual costs may be higher or lower,
based on these assumptions your costs would be:

The hypothetical example assumes that a CDSC will not apply to redemptions of
Class A Shares within the first 18 months. Class B Shares convert to Class A
Shares eight years after purchase; therefore, Class A expenses are used in the
hypothetical example after year eight.
 
Certain institutions that sell Portfolio Shares and/or their salespersons may
receive other compensation in connection with the sale and distribution of
Class A, Class B and Class C Shares or for services to their customers'
accounts and/or the Portfolios. For additional information regarding such com-
pensation, see "What Should I Know When I Purchase Shares Through An Authorized
Dealer?"

 The difference, if any, between the stated fees and the actual fees paid by
 the Portfolios reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
                                                                              35

In addition, each Portfolio, as a shareholder in the Underlying Funds, will
indirectly bear a proportionate share of any investment management fees and
other expenses paid by the Underlying Funds. The following chart shows the cur-
rent total net operating expense ratios (management fee plus other operating
expenses) of Institutional Shares of each Underlying Fund in which the Portfo-
lios may invest after applicable fee waivers and expense limitations. In addi-
tion, the following chart shows the contractual investment management fees pay-
able to the investment adviser and its affiliates by the Underlying Funds (in
each case as an annualized percentage of a Fund's average net assets). Absent
voluntary fee waivers and/or expense reimbursements, which may be discontinued
at any time, the total operating expense ratios of certain Underlying Funds
would be higher.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Portfolio's shares.
 Goldman Sachs, 4900 Sears Tower, Chicago, Illinois, 60606-6372, also serves
 as each Portfolio's transfer agent (the "Transfer Agent") and, as such, per-
 forms various shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Underlying Funds or Portfolios. Goldman Sachs reserves
 the right to redeem at any time some or all of the shares acquired for its
 own amount.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to an Underlying Fund or limit an Underlying Fund's investment activities.
 Goldman Sachs and its affiliates engage in proprietary trading and advise
 accounts and funds which have investment objectives similar to those of the
 Underlying Funds and/or which engage in and compete for transactions in the
 same types of securities, currencies and instruments as the Underlying
 Funds. Goldman Sachs and its affiliates will not have any obligation to make
 available any information regarding their proprietary activities or strate-
 gies, or the activities or strategies used for other accounts managed by
 them, for the benefit of the management of the Underlying Funds.

 The results of an Underlying Fund's investment activities, therefore, may
 differ from those of Goldman Sachs and its affiliates, and it is possible
 that an Underlying Fund could sustain losses during periods in which Goldman
 Sachs and its affiliates and other accounts achieve significant profits on
 their trading for proprietary or other accounts. In addition, the Underlying
 Funds may, from time to time, enter into transactions in which other clients
 of Goldman Sachs have an adverse interest. An Underlying Fund's activities
 may be limited because of regulatory restrictions applicable to Goldman
 Sachs and its affiliates, and/or their internal policies designed to comply
 with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Portfolios and the Underlying Funds could be
 adversely affected in their ability to process securities trades, price
 securities, provide shareholder account services and otherwise conduct nor-
 mal business operations if the Investment Adviser or other service providers
 do not adequately address this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Portfolios' other
  service providers that they are taking the steps necessary so that they do
  not experience Year 2000 Problems, and the Investment Adviser will continue
  to monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Portfolios at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the
 
                                                                              39

 issuers of securities held by the Portfolios. The Investment Adviser may
 obtain such Year 2000 information from various sources which the Investment
 Adviser believes to be reliable, including the issuers' public regulatory
 filings. However, the Investment Adviser is not in a position to verify the
 accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Portfolios' other service providers will be
 sufficient to avoid any adverse effect on the Portfolios due to the Year
 2000 Problem.

Dividends
 
Each Fund pays dividends from its net investment income and distributions from
net realized capital gains. You may choose to have dividends and distributions
paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund. Spe-
 cial restrictions may apply for certain ILA Portfolios. See the Additional
 Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from net capital gains
are declared and paid as follows:

From time to time a portion of a Portfolio's dividends may constitute a return
of capital.
 
At the time of an investor's purchase of shares of a Portfolio, a portion of
the NAV per share may be represented by undistributed income or realized or
unrealized appreciation of the Portfolio's portfolio securities. Therefore,
subsequent distributions on such shares from such income or realized apprecia-
tion may be taxable to the investor even if the NAV of the shares is, as a
result of the distributions, reduced below the cost of such shares and the dis-
tributions (or portions thereof) represent a return of a portion of the pur-
chase price.

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Refuse to open an account if you fail to (i) provide a social security num-
  ber or other taxpayer identification number; or (ii) certify that such num-
  ber is correct (if required to do so under applicable law).
 .Reject or restrict any purchase or exchange order by a particular purchaser
  (or group of related purchasers). This may occur, for example, when a pat-
  tern of
 
                                                                              43

  frequent purchases, sales or exchanges of shares of a Fund is evident, or
  if purchases, sales or exchanges are, or a subsequent abrupt redemption
  might be, of a size that would disrupt management of a Fund.
 .Modify or waive the minimum investment amounts.
 .Modify the manner in which shares are offered.
 .Modify the sales charge rates applicable to future purchases of shares.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange shares is deter-
 mined by a Fund's NAV and share class. Each class calculates its NAV as fol-
 lows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV =
               -------------------------------
                 Number of Outstanding Shares of the Class
 
 The Funds' investments are valued based on market quotations or if accurate
 quotations are not readily available, the fair value of the Fund's invest-
 ments may be determined in good faith under procedures established by the
 Trustees.
 
 .NAV per share of each share class is calculated by the Fund's custodian on
  each business day as of the close of regular trading on the New York Stock
  Exchange (normally 4:00 p.m. New York time). Fund shares will not be priced
  on any day the New York Stock Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form, plus any applicable sales charge.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form, less any applicable CDSC.
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if
 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 In addition, the impact of events that occur after the publication of market
 quotations used by a Fund to price its securities but before the close of
 regular trading on the New York Stock Exchange will normally not be
 reflected in a Fund's next

 determined NAV unless the Trust, in its discretion, makes an adjustment in
 light of the nature and materiality of the event, its effect on Fund opera-
 tions and other relevant factors.
 
 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS A SHARES
 
 What Is The Offering Price Of Class A Shares?
 The offering price of Class A Shares of each Fund is the next determined NAV
 per share plus an initial sales charge paid to Goldman Sachs at the time of
 purchase of shares. The sales charge varies depending upon the amount you
 purchase. In some cases, described below, the initial sales charge may be
 eliminated altogether, and the offering price will be the NAV per share. The
 current sales charges and commissions paid to Authorized Dealers are as fol-
 lows:

     Authorized Dealers to whom substantially the entire sales charge is
     allowed may be deemed to be "underwriters" under the Securities Act of
     1933.
  ** No sales charge is payable at the time of purchase of Class A Shares of
     $1 million or more, but a CDSC of 1% may be imposed in the event of cer-
     tain redemptions within 18 months of purchase.
 *** The Distributor pays a one-time commission to Authorized Dealers who
     initiate or are responsible for purchases of $1 million or more of
     shares of the Funds equal to 1.00% of the amount under $3 million, 0.50%
     of the next $2 million, and 0.25% thereafter. The Distributor may also
     pay, with respect to all or a portion of the amount purchased, a commis-
     sion in accordance with the foregoing schedule to Authorized Dealers who
     initiate or are responsible for purchases of $500,000 or more by certain
     pension and profit sharing plans, pension funds and other company-spon-
     sored benefit plans investing in the Funds which satisfy the criteria
     set forth below in "When Are Class A Shares Not Subject To A Sales
     Load?" or $1 million or more by certain "wrap" accounts. Purchases by
     such plans will be made at NAV with no initial sales charge, but if all
     of the shares held are redeemed within 18 months after the end of the
     calendar month in which such purchase was made, a CDSC of 1% may be
     imposed upon the plan sponsor or the third party administrator. In addi-
     tion, Authorized Dealers will remit to the Distributor such payments
     received in connection with "wrap" accounts in the event that shares are
     redeemed within 18 months after the end of the calendar month in which

 What Else Do I Need To Know About Class A Shares' CDSC?
 Purchases of $1 million or more of Class A Shares will be made at NAV with
 no initial sales charge. However, if you redeem shares within 18 months
 after the end of the calendar month in which the purchase was made, exclud-
 ing any period of time in which the shares were exchanged into and remained
 invested in an equivalent class of an ILA Portfolio, a CDSC of 1% may be
 imposed. The CDSC may not be imposed if your Authorized Dealer enters into
 an agreement with the Distributor to return all or an applicable prorated
 portion of its commission to the Distributor. The CDSC is waived on redemp-
 tions in certain circumstances. See "In What Situations May The CDSC On
 Class A, B Or C Shares Be Waived Or Reduced?" below.
 
 When Are Class A Shares Not Subject To A Sales Load?
 Class A Shares of the Funds may be sold at NAV without payment of any sales
 charge to the following individuals and entities:
 .Goldman Sachs, its affiliates or their respective officers, partners,
  directors or employees (including retired employees and former partners),
  any partnership of which Goldman Sachs is a general partner, any Trustee or
  officer of the Trust and designated family members of any of these individ-
  uals;
 .Qualified retirement plans of Goldman Sachs;
 .Trustees or directors of investment companies for which Goldman Sachs or an
  affiliate acts as sponsor;
 .Any employee or registered representative of any Authorized Dealer or their
  respective spouses, children and parents;
 .Banks, trust companies or other types of depository institutions investing
  for their own account or investing for discretionary or non-discretionary
  accounts;
 .Any state, county or city, or any instrumentality, department, authority or
  agency thereof, which is prohibited by applicable investment laws from pay-
  ing a sales charge or commission in connection with the purchase of shares
  of a Fund;
 .Pension and profit sharing plans, pension funds and other company-sponsored
  benefit plans that:
  .Buy shares of Goldman Sachs Funds worth $500,000 or more; or
  .Have 100 or more eligible employees at the time of purchase; or
  .Certify that they expect to have annual plan purchases of shares of
   Goldman Sachs Funds of $200,000 or more; or
  .Are provided administrative services by certain third-party administra-
   tors that have entered into a special service arrangement with Goldman
   Sachs relating to such plans; or
  .Have at the time of purchase aggregate assets of at least $2,000,000;

                                                               SHAREHOLDER GUIDE
 
 ."Wrap" accounts for the benefit of clients of broker-dealers, financial
  institutions or financial planners, provided they have entered into an
  agreement with GSAM specifying aggregate minimums and certain operating
  policies and standards;
 .Registered investment advisers investing for accounts for which they
  receive asset-based fees;
 .Accounts over which GSAM or its advisory affiliates have investment discre-
  tion; or
 .Shareholders receiving distributions from a qualified retirement plan
  invested in the Goldman Sachs Funds and reinvesting such proceeds in a
  Goldman Sachs IRA.
 
 You must certify eligibility for any of the above exemptions on your Account
 Application and notify the Fund if you no longer are eligible for the exemp-
 tion. The Fund will grant you an exemption subject to confirmation of your
 entitlement. You may be charged a fee if you effect your transactions
 through a broker or agent.
 
 How Can The Sales Charge On Class A Shares Be Reduced?
 .Right of Accumulation: When buying Class A Shares in Goldman Sachs Funds,
  your current aggregate investment determines the initial sales load you
  pay. You may qualify for reduced sales charges when the current market
  value of holdings (shares at current offering price), plus new purchases,
  reaches $50,000 or more. Class A Shares of any of the Goldman Sachs Funds
  may be combined under the Right of Accumulation. To qualify for a reduced
  sales load, you or your Authorized Dealer must notify the Funds' Transfer
  Agent at the time of investment that a quantity discount is applicable. Use
  of this service is subject to a check of appropriate records. The Addi-
  tional Statement has more information about the Right of Accumulation.
 .Statement of Intention: You may obtain a reduced sales charge by means of a
  written Statement of Intention which expresses your non-binding commitment
  to invest in the aggregate $50,000 or more (not counting reinvestments of
  dividends and distributions) within a period of 13 months in Class A Shares
  of one or more Goldman Sachs Fund. Any investments you make during the
  period will receive the discounted sales load based on the full amount of
  your investment commitment. If the investment commitment of the Statement
  of Intention is not met prior to the expiration of the 13-month period, the
  entire amount will be subject to the higher applicable sales charge. By
  signing the Statement of Intention, you authorize the Transfer Agent to
  escrow and redeem Class A Shares in your account to pay this additional
  charge. The Additional Statement has more information about the Statement
  of Intention, which you should read carefully.
 
                                                                              47

 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS B SHARES
 
 
 What Is The Offering Price Of Class B Shares?
 You may purchase Class B Shares of the Funds at the next determined NAV
 without an initial sales charge. However, Class B Shares redeemed within six
 years of purchase will be subject to a CDSC at the rates shown in the table
 below based on how long you held your shares.
 
 The CDSC schedule is as follows:
 
<TABLE>
<CAPTION>
                             CDSC as a
                           Percentage of
                           Dollar Amount
  Year Since Purchase     Subject to CDSC
 ----------------------------------------
  <S>                     <C>
  First                          5%
  Second                         4%
  Third                          3%
  Fourth                         3%
  Fifth                          2%
  Sixth                          1%
  Seventh and thereafter       None
 ----------------------------------------
</TABLE>
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class B Shares, including the payment of compensation to Authorized Dealers.
 A commission equal to 4% of the amount invested is paid to Authorized Deal-
 ers.
 
 What Should I Know About The Automatic Conversion Of Class B Shares?
 Class B Shares of a Fund will automatically convert into Class A Shares of
 the same Fund at the end of the calendar quarter that is eight years after
 the purchase date.
 
 If you acquire Class B Shares of a Fund by exchange from Class B Shares of
 another Goldman Sachs Fund, your Class B Shares will convert into Class A
 Shares of such Fund based on the date of the initial purchase and the CDSC
 schedule of that purchase.
 
 If you acquire Class B Shares through reinvestment of distributions, your
 Class B Shares will convert into Class A Shares based on the date of the
 initial purchase of the shares on which the distribution was paid.
 
 The conversion of Class B Shares to Class A Shares will not occur at any
 time the Funds are advised that such conversions may constitute taxable
 events for federal tax purposes, which the Funds believe is unlikely. If
 conversions do not occur as a

 result of possible taxability, Class B Shares would continue to be subject
 to higher expenses than Class A Shares for an indeterminate period.
 
 A COMMON QUESTION ABOUT THE PURCHASE OF CLASS C SHARES
 
 
 What Is The Offering Price Of Class C Shares?
 You may purchase Class C Shares of the Funds at the next determined NAV
 without paying an initial sales charge. However, if you redeem Class C
 Shares within 12 months of purchase, a CDSC of 1% will be deducted from the
 redemption proceeds; provided that in connection with purchases by pension
 and profit sharing plans, pension funds and other company-sponsored benefit
 plans, where all of the Class C Shares are redeemed within 12 months of pur-
 chase, a CDSC of 1% may be imposed upon the plan sponsor or third party
 administrator.
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class C Shares, including the payment of compensation to Authorized Dealers.
 An amount equal to 1% of the amount invested is paid by the Distributor to
 Authorized Dealers.
 
 COMMON QUESTIONS APPLICABLE TO THE PURCHASE OF CLASS A, B
 AND C SHARES
 
 
 What Else Do I Need To Know About The CDSC On Class A, B Or C Shares?
 .The CDSC is based on the lesser of the NAV of the shares at the time of
  redemption or the original offering price (which is the original NAV).
  .No CDSC is charged on shares acquired from reinvested dividends or capi-
   tal gains distributions.
  .No CDSC is charged on the per share appreciation of your account over the
   initial purchase price.
  .When counting the number of months since a purchase of Class B or Class C
   Shares was made, all payments made during a month will be combined and
   considered to have been made on the first day of that month.
 .To keep your CDSC as low as possible, each time you place a request to sell
  shares, the Funds will first sell any shares in your account that do not
  carry a CDSC and then the shares in your account that have been held the
  longest.
 
                                                                              49
<PAGE>
 
 
 In What Situations May The CDSC On Class A, B Or C Shares Be Waived Or
 Reduced?
 The CDSC on Class A, Class B and Class C Shares that are subject to a CDSC
 may be waived or reduced if the redemption relates to:
 .Retirement distributions or loans to participants or beneficiaries from
  pension and profit sharing plans, pension funds and other company-sponsored
  benefit plans (each a "Retirement Plan");
 .The death or disability (as defined in Section 72(m)(7) of the Internal
  Revenue Code of 1986, as amended (the "Code")) of a participant or benefi-
  ciary in a Retirement Plan;
 .Hardship withdrawals by a participant or beneficiary in a Retirement Plan;
 .Satisfying the minimum distribution requirements of the Code;
 .Establishing "substantially equal periodic payments" as described under
  Section 72(t)(2) of the Code;
 .The separation from service by a participant or beneficiary in a Retirement
  Plan;
 .The death or disability (as defined in Section 72(m)(7) of the Code) of a
  shareholder if the redemption is made within one year of the event;
 .Excess contributions distributed from a Retirement Plan;
 .Distributions from a qualified Retirement Plan invested in the Goldman
  Sachs Funds which are being rolled over to a Goldman Sachs IRA; or
 .Redemption proceeds which are to be reinvested in accounts or non-regis-
  tered products over which GSAM or its advisory affiliates have investment
  discretion.
 
 In addition, Class A, B and C Shares subject to a systematic withdrawal plan
 may be redeemed without a CDSC. The Funds reserve the right to limit such
 redemptions, on an annual basis, to 12% each of the value of your Class B
 and C Shares and 10% of the value of your Class A Shares.
 
 How Do I Decide Whether To Buy Class A, B Or C Shares?
 The decision as to which Class to purchase depends on the amount you invest,
 the intended length of the investment and your personal situation.
 
 .Class A Shares. If you are making an investment of $50,000 or more that
  qualifies for a reduced sales charge, you should consider purchasing Class
  A Shares.
 .Class B Shares. If you plan to hold your investment for at least six years
  and would prefer not to pay an initial sales charge, you might consider
  purchasing Class B Shares. By not paying a front-end sales charge, your
  entire investment in Class B Shares is available to work for you from the
  time you make your initial investment. However, the distribution and serv-
  ice fee paid by Class B

<PAGE>
 
                                                               SHAREHOLDER GUIDE
 
  Shares will cause your Class B Shares (until conversion to Class A Shares)
  to have a higher expense ratio, and thus, lower performance and lower divi-
  dend payments (to the extent dividends are paid) than Class A Shares.
  A maximum purchase limitation of $250,000 in the aggregate normally
  applies to Class B Shares.
 .Class C Shares. If you are unsure of the length of your investment or plan
  to hold your investment for less than six years and would prefer not to pay
  an initial sales charge, you may prefer Class C Shares. By not paying a
  front-end sales charge, your entire investment in Class C Shares is avail-
  able to work for you from the time you make your initial investment. Howev-
  er, the distribution and service fee paid by Class C Shares will cause your
  Class C Shares to have a higher expense ratio, and thus lower performance
  and lower dividend payments (to the extent dividends are paid) than Class A
  Shares (or Class B Shares after conversion to Class A Shares).
  Although Class C Shares are subject to a CDSC for only 12 months, Class C
  Shares do not have the conversion feature applicable to Class B Shares and
  your investment will therefore pay higher distribution fees indefinitely.
  A maximum purchase limitation of $1,000,000 in the aggregate normally
  applies to purchases of Class C Shares.
 
 Note: Authorized Dealers may receive different compensation for selling
 Class A, Class B or Class C Shares.
 
 In addition to Class A, Class B and Class C Shares, each Fund also offers
 other classes of shares to investors. These other share classes are subject
 to different fees and expenses (which affect performance), have different
 minimum investment requirements and are entitled to different services.
 Information regarding these other share classes may be obtained from your
 sales representative or from Goldman Sachs by calling the number on the back
 cover of this Prospectus.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Class A, Class B And Class C Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Each Fund will redeem its shares upon request on
 any business day at the NAV next determined after receipt of such request in
 proper form, subject to any applicable CDSC. You may request that redemption
 proceeds be sent to you by check or by wire (if the wire instructions are on
 record). Redemptions may be requested in writing or by telephone.
 
                                                                              51

                    within any 7 calendar day period
                   .Proceeds which are sent directly to a Goldman
                    Sachs brokerage account are not subject to the
                    $50,000 limit
 --------------------------------------------------------------------
</TABLE>
 When Do I Need A Signature Guarantee To Redeem Shares?
 A signature guarantee is required if:
 .You are requesting in writing to redeem shares in an amount over $50,000;
 .You would like the redemption proceeds sent to an address that is not your
  address of record; or
 .You would like to change the bank designated on your Account Application.
 
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federal savings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.
 Additional documentation may be required for executors, trustees or corpora-
 tions or when deemed appropriate by the Transfer Agent.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 The Trust may accept telephone redemption instructions from any person iden-
 tifying himself or
 
52
<PAGE>
 
                                                               SHAREHOLDER GUIDE
 
 herself as the owner of an account or the owner's registered representative
 where the owner has not declined in writing to use this service. Thus, you
 risk possible losses if a telephone redemption is not authorized by you.
 
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs and NFDS each employ reasonable proce-
 dures specified by the Trust to confirm that such instructions are genuine.
 If reasonable procedures are not employed, the Trust may be liable for any
 loss due to unauthorized or fraudulent transactions. The following general
 policies are currently in effect:
 .All telephone requests are recorded.
 .Proceeds of telephone redemption requests will be sent only to your address
  of record or authorized bank account designated in the Account Application
  (unless you provide written instructions and a signature guarantee, indi-
  cating another address or account) and exchanges of shares normally will be
  made only to an identically registered account.
 .Telephone redemptions will not be accepted during the 30-day period follow-
  ing any change in your address of record.
 .The telephone redemption option does not apply to shares held in a "street
  name" account. "Street name" accounts are accounts maintained and serviced
  by your Authorized Dealer. If your account is held in "street name," you
  should contact your registered representative of record, who may make tele-
  phone redemptions on your behalf.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: You may arrange for your redemption proceeds to be wired as federal
 funds to the bank account designated in your Account Application. The fol-
 lowing general policies govern wiring redemption proceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If you are selling shares you recently paid for by
  check, the Fund will pay you when your check has cleared, which may take up
  to 15 days. If the Federal Reserve Bank is closed on the day that the
  redemption proceeds would ordinarily be wired, wiring the redemption pro-
  ceeds may be delayed one additional business day.
 .A transaction fee of $7.50 may be charged for payments of redemption pro-
  ceeds by wire. Your bank may also charge wiring fees. You should contact
  your bank directly to learn whether it charges such fees.
 
                                                                              53
<PAGE>
 
 .To change the bank designated on your Account Application, you must send
  written instructions (with your signature guaranteed) to the Transfer
  Agent.
 .Neither the Trust, Goldman Sachs nor any Authorized Dealer assume any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
 By Check: You may elect to receive your redemption proceeds by check.
 Redemption proceeds paid by check will normally be mailed to the address of
 record within three business days of a properly executed redemption request.
 If you are selling shares you recently paid for by check, the Fund will pay
 you when your check has cleared, which may take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 Additional documentation may be required when deemed appropriate by the
 Transfer Agent. A redemption request will not be in proper form until such
 additional documentation has been received.
 
 The Trust reserves the right to:
 .Redeem your shares if your account balance is less than $50 as a result of
  a redemption. The Fund will not redeem your shares on this basis if the
  value of your account falls below the minimum account balance solely as a
  result of market conditions. The Fund will give you 60 days' prior written
  notice to allow you to purchase sufficient additional shares of the Fund in
  order to avoid such redemption.
 .Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Reinvest Redemption Proceeds In The Same Or Another Goldman Sachs
 Fund?
 You may redeem shares of a Fund and reinvest a portion or all of the redemp-
 tion proceeds (plus any additional amounts needed to round off purchases to
 the nearest full share) at NAV. To be eligible for this privilege, you must
 hold the shares you want to redeem for at least 30 days and you must rein-
 vest the share proceeds within 90 days after you redeem. You may reinvest as
 follows:
  .Class A or B Shares--Class A Shares of the same Fund or any other Goldman
   Sachs Fund
  .Class C Shares--Class C Shares of the same Fund or any other Goldman
   Sachs Fund

 .You should obtain and read the applicable prospectuses before investing in
  any other Funds.
 .If you pay a CDSC upon redemption of Class A or Class C Shares and then
  reinvest in Class A or Class C Shares as described above, your account will
  be credited with the amount of the CDSC you paid. The reinvested shares
  will, however, continue to be subject to a CDSC. The holding period of the
  shares acquired through reinvestment will include the holding period of the
  redeemed shares for purposes of computing the CDSC payable upon a subse-
  quent redemption. For Class B Shares, you may reinvest the redemption pro-
  ceeds in Class A Shares at NAV but the amount of the CDSC paid upon redemp-
  tion of the Class B Shares will not be credited to your account.
 .The reinvestment privilege may be exercised at any time in connection with
  transactions in which the proceeds are reinvested at NAV in a tax-sheltered
  retirement plan. In other cases, the reinvestment privilege may be exer-
  cised once per year upon receipt of a written request.
 .You may be subject to tax as a result of a redemption. You should consult
  your tax adviser concerning the tax consequences of a redemption and rein-
  vestment.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange shares of a Fund at NAV without the imposition of an ini-
 tial sales charge or CDSC at the time of exchange for shares of the same
 class or an equivalent class of any other Goldman Sachs Fund. The exchange
 privilege may be materially modified or withdrawn at any time upon 60 days'
 written notice to you.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
 acquiring before making an exchange.
 .Six free exchanges are allowed in each 12 month period.
 .A $12.50 fee may be charged for each subsequent exchange.
 .There is no charge for exchanges made pursuant to the Automatic Exchange Pro-
 gram.
 .The exchanged shares may later be exchanged for shares of the same class (or
 an equivalent class) of the original Fund at the next determined NAV without
 the imposition of an initial sales charge or CDSC if the amount in the Fund
 resulting from such exchanges is less than the largest amount on which you
 have previously paid the applicable sales charge.
 .When you exchange shares subject to a CDSC, no CDSC will be charged at that
 time. The exchanged shares will be subject to the CDSC of the shares origi-
 nally held. For purposes of determining the amount of the applicable CDSC, the
 length of time you have owned the shares will be measured from the date you
 acquired the original shares subject to a CDSC and will not be affected by a
 subsequent exchange.
 .Eligible investors may exchange certain classes of shares for another class of
 shares of the same Fund. For further information, call Goldman Sachs Funds at
 1-800-526-7384.
 .All exchanges which represent an initial investment in a Fund must satisfy the
 minimum initial investment requirements of that Fund.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic economic
 or market conditions.
 .Goldman Sachs and NFDS may use reasonable procedures described under "What Do
 I Need to Know About Telephone Redemption Requests?" in an effort to prevent
 unauthorized or fraudulent telephone exchange requests.
 .Telephone exchanges normally will be made only to an identically registered
 account. Shares may be exchanged among accounts with different names,
 addresses and social security or other taxpayer identification numbers only if
 the exchange instructions are in writing and accompanied by a signature
 guarantee.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.

 SHAREHOLDER SERVICES
 
 
 Can I Arrange To Have Automatic Investments Made On A Regular Basis?
 You may be able to make systematic cash investments through your bank via
 ACH transfer or your checking account via bank draft each month. Forms for
 this option are available from Goldman Sachs, your Authorized Dealer or you
 may check the appropriate box on the Account Application.
 
 Can My Dividends And Distributions From A Fund Be Invested In Other Funds?
 You may elect to cross-reinvest dividends and capital gain distributions
 paid by a Fund in shares of the same class or an equivalent class of any
 other Goldman Sachs Fund.
 .Shares will be purchased at NAV.
 .No initial sales charge or CDSC will be imposed.
 .You may elect cross-reinvestment into an identically registered account or
  an account registered in a different name or with a different address,
  social security number or taxpayer identification number provided that the
  account has been properly established, appropriate signature guarantees
  obtained and the minimum initial investment has been satisfied.
 
 Can I Arrange To Have Automatic Exchanges Made On A Regular Basis?
 You may elect to exchange automatically a specified dollar amount of shares
 of a Fund for shares of the same class or an equivalent class of any other
 Goldman Sachs Fund.
 .Shares will be purchased at NAV.
 .No initial sales charge is imposed.
 .Shares subject to a CDSC acquired under this program may be subject to a
  CDSC at the time of redemption from the Fund into which the exchange is
  made depending upon the date and value of your original purchase.
 .Automatic exchanges are made monthly on the 15th day of each month or the
  first business day thereafter.
 .Minimum dollar amount: $50 per month.
 
 What Else Should I Know About Cross-Reinvestments And Automatic Exchanges?
 Cross-reinvestments and automatic exchanges are subject to the following
 conditions:
 .You must hold $5,000 or more in the Fund which is paying the dividend or
  from which the exchange is being made.
 
                                                                              57
<PAGE>
 
 .You must invest an amount in the Fund into which cross-reinvestments or
  automatic exchanges are being made that is equal to that Fund's minimum
  initial investment or continue to cross-reinvest or to make automatic
  exchanges until such minimum initial investment is met.
 .You should obtain and read the prospectus of the Fund into which dividends
  are invested or automatic exchanges are made.
 
 Can I Have Automatic Withdrawals Made On A Regular Basis?
 You may draw on your account systematically via check or ACH transfer in any
 amount of $50 or more.
 .It is normally undesirable to maintain a systematic withdrawal plan at the
  same time that you are purchasing additional Class A, Class B or Class C
  Shares because of the sales charge imposed on your purchases of Class A
  Shares or the imposition of a CDSC on your redemptions of Class A, Class B
  or Class C Shares.
 .You must have a minimum balance of $5,000 in a Fund.
 .Checks are mailed on or about the 25th day of each month.
 .Each systematic withdrawal is a redemption and therefore a taxable transac-
  tion.
 .The CDSC applicable to Class A, Class B or Class C Shares redeemed under
  the systematic withdrawal plan may be waived.
 
 What Types of Reports Will I Be Sent Regarding My Investment?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-526-7384. You will also be provided with a
 printed confirmation for each transaction in your account and an individual
 quarterly account statement. A year-to-date statement for your account will
 be provided upon request made to Goldman Sachs. If your account is held in
 "street name" you may receive your statement and confirmations on a differ-
 ent schedule. The Funds do not generally provide sub-accounting services.
 
 What Should I Know When I Purchase Shares Through An Authorized Dealer?
 Authorized Dealers and other financial intermediaries may provide varying
 arrangements for their clients to purchase and redeem Fund shares. They may
 charge additional fees not described in this Prospectus to their customers
 for such services.
 
 If shares of a Fund are held in a "street name" account with an Authorized
 Dealer, all recordkeeping, transaction processing and payments of distribu-
 tions relating to your account will be performed by the Authorized Dealer,
 and not by the Fund and its Transfer Agent. Since the Funds will have no
 record of your

                                                               SHAREHOLDER GUIDE
 
 transactions, you should contact the Authorized Dealer to purchase, redeem
 or exchange shares, to make changes in or give instructions concerning the
 account or to obtain information about your account. The transfer of shares
 in a "street name" account to an account with another dealer or to an
 account directly with the Fund involves special procedures and will require
 you to obtain historical purchase information about the shares in the
 account from the Authorized Dealer.
 
 Authorized Dealers and other financial intermediaries may be authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and if approved by the Trust, to
 designate other intermediaries to accept such orders. In these cases:
 .A Fund will be deemed to have received an order that is in proper form when
  the order is accepted by an Authorized Dealer or intermediary on a business
  day, and the order will be priced at the Fund's NAV per share (adjusted for
  any applicable sales charge) next determined after such acceptance.
 .Authorized Dealers and intermediaries are responsible for transmitting
  accepted orders to the Funds within the time period agreed upon by them.
 
 You should contact your Authorized Dealer or intermediary to learn whether
 it is authorized to accept orders for the Trust.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Authorized Dealers and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Autho-
 rized Dealers depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 DISTRIBUTION SERVICES AND FEES
 
 
 What Are The Different Distribution And Service Fees Paid By Class A, B and
 C Shares?
 The Trust has adopted distribution and service plans (each a "Plan") under
 which Class A, Class B and Class C Shares bear distribution and service fees
 paid to Authorized Dealers and Goldman Sachs. If the fees received by
 Goldman Sachs pursuant to the Plans exceed its expenses, Goldman Sachs may
 realize a profit from
 
                                                                              59
<PAGE>
 
 their arrangements. Goldman Sachs pays the distribution and service fees on
 a quarterly basis.
 
 Under the Plans, Goldman Sachs is entitled to a monthly fee from each Fund
 for distribution services equal, on an annual basis, to 0.25%, 0.75% and
 0.75%, respectively, of a Fund's average daily net assets attributed to
 Class A, Class B and Class C Shares. Because these fees are paid out of the
 Fund's assets on an ongoing basis, over time, these fees will increase the
 cost of your investment and may cost you more than paying other types of
 such charges.
 
 The distribution fees are subject to the requirements of Rule 12b-1 under
 the Act, and may be used (among other things) for:
 .Compensation paid to and expenses incurred by Authorized Dealers, Goldman
  Sachs and their respective officers, employees and sales representatives;
 .Commissions paid to Authorized Dealers;
 .Allocable overhead;
 .Telephone and travel expenses;
 .Interest and other costs associated with the financing of such compensation
  and expenses;
 .Printing of prospectuses for prospective shareholders;
 .Preparation and distribution of sales literature or advertising of any
  type; and
 .All other expenses incurred in connection with activities primarily
  intended to result in the sale of Class A, Class B and Class C Shares.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.75% distribution fee as an ongoing commission to Authorized Dealers
 after the shares have been held for one year.
 
 PERSONAL ACCOUNT MAINTENANCE SERVICES AND FEES
 
 
 Under the Plans, Goldman Sachs is also entitled to receive a separate fee
 equal on an annual basis to 0.25% of each Fund's average daily net assets
 attributed to Class B or Class C Shares. This fee is for personal and
 account maintenance services, and may be used to make payments to Goldman
 Sachs, Authorized Dealers and their officers, sales representatives and
 employees for responding to inquiries of, and furnishing assistance to,
 shareholders regarding ownership of their shares or their accounts or simi-
 lar services not otherwise provided on behalf of the Funds. If the fees
 received by Goldman Sachs pursuant to the Plans exceed its expenses, Goldman
 Sachs may realize a profit from this arrangement.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.25% service fee to Authorized Dealers after the shares have been held
 for one year.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Portfolio distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Portfolio's net investment income, certain net real-
 ized foreign exchange gains and net short-term capital gains. They are tax-
 able as long-term capital gains to the extent they are attributable to the
 Portfolio's excess of net long-term capital gains (including long-term capi-
 tal gain distributions received from Underlying Fund investments) over net
 short-term capital losses. The tax status of any distribution is the same
 regardless of how long you have been in the Portfolio and whether you rein-
 vest in additional shares or take the distribution as cash. Certain distri-
 butions paid by a Portfolio in January of a given year may be taxable to
 shareholders as if received the prior December 31. The tax status and
 amounts of the distributions for each calendar year will be detailed in your
 annual tax statement from the Portfolio.
 
 The REIT investments of the underlying Real Estate Securities Fund often do
 not provide complete tax information to the Fund until after the calendar
 year-end. Consequently, because of the delay, it may be necessary for the
 Asset Allocation Portfolios to request permission to extend the deadline for
 issuance of Forms 1099-DIV beyond January 31.
 
 A Portfolio's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Portfolio receives from Underlying
 Fund investments may be eligible, in the hands of the corporate sharehold-
 ers, for the corporate dividends-received deduction, subject to certain
 holding period requirements and debt financing limitations.
 
 There are certain tax requirements that all Portfolios must follow in order
 to avoid federal taxation. In its efforts to adhere to these requirements,
 the Portfolios may have to limit their investment activity in some types of
 instruments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Portfolio shares may generate a tax liability (un-
 less your investment is in an IRA or other tax-advantaged account). Depend-
 ing upon the purchase or sale price of the shares you sell or exchange, you
 may have a gain or a loss on the transaction.
 
                                                                              61
<PAGE>
 
 
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Portfolio, based on
 the difference between your tax basis in the shares and the amount you
 receive for them. (To aid in computing your tax basis, you generally should
 retain your account statements for the periods that you hold shares.) Any
 loss recognized on shares held for six months or less will be treated as a
 long-term capital loss to the extent of any capital gain dividends that were
 received with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from a Portfolio or on the value of the
 shares held by you. More tax information is provided in the Additional
 Statement. You should also consult your own tax adviser for information
 regarding all tax consequences applicable to your investments in the Portfo-
 lios.

Appendix A
Additional Information on the Underlying Funds
 This Appendix provides further information on certain types of securities
 and techniques that may be used by the Underlying Funds, including their
 associated risks. Additional information is provided in the Additional
 Statement, which is available upon request, and in the prospectuses of the
 Underlying Funds.
 
 The Underlying Equity Funds invest primarily in common stocks and other
 equity securities, including preferred stocks, interests in real estate
 investment trusts, convertible debt obligations, convertible preferred
 stocks, equity interests in trusts, partnerships, joint ventures, limited
 liability companies and similar enterprises, warrants and stock purchase
 rights ("equity securities"). The Underlying Fixed-Income Funds invest pri-
 marily in fixed-income securities, including senior and subordinated corpo-
 rate debt obligations (such as bonds, debentures, notes and commercial
 paper), convertible and non-convertible corporate debt obligations, loan
 participations and preferred stock.
 
 The Short-Duration Government and Adjustable Rate Government Funds invest in
 U.S. Government Securities and related repurchase agreements, and neither of
 these Underlying Funds, the Government Income Fund nor the Financial Square
 Prime Obligations Fund makes foreign investments. The investments of the
 Financial Square Prime Obligations Fund are limited by SEC regulations
 applicable to money market funds as described in its prospectus, and do not
 include many of the types of investments discussed below that are permitted
 for the other Underlying Funds. With these exceptions, and the further
 exceptions noted below, the following description applies generally to the
 Underlying Funds.
 
 A. General Risks of the Underlying Funds
 
 The Underlying Equity Funds will be subject to the risks associated with
 common stocks and other equity securities. In general, stock values fluctu-
 ate in response to the activities of individual companies and in response to
 general market and economic conditions. Accordingly, the value of the stocks
 that an Underlying Fund holds may decline over short or extended periods.
 The stock markets tend to be cyclical, with periods when stock prices gener-
 ally rise and periods when prices generally decline.
 
 The Underlying Fixed-Income Funds will be subject to the risks associated
 with fixed-income securities. These risks include interest rate risk, credit
 risk and call/extension risk. In general, interest rate risk involves the
 risk that when interest
 
                                                                              63
<PAGE>
 
 
 rates decline, the market value of fixed-income securities tends to
 increase. Conversely, when interest rates increase, the market value of
 fixed-income securities tends to decline. Credit risk involves the risk that
 an issuer could default on its obligations, and an Underlying Fund will not
 recover its investment. Call risk and extension risk are normally present in
 adjustable rate mortgage loans ("ARMs"), mortgage-backed securities and
 asset-backed securities. For example, homeowners have the option to prepay
 their mortgages. Therefore, the duration of a security backed by home mort-
 gages can either shorten (call risk) or lengthen (extension risk). In gener-
 al, if interest rates on new mortgage loans fall sufficiently below the
 interest rates on existing outstanding mortgage loans, the rate of prepay-
 ment would be expected to increase. Conversely, if mortgage loan interest
 rates rise above the interest rates on existing outstanding mortgage loans,
 the rate of prepayment would be expected to decrease. In either case, a
 change in the prepayment rate can result in losses to investors.
 
 The Financial Square Prime Obligations Fund attempts to maintain a stable
 NAV of $1.00 per share and values its assets using the amortized cost method
 in accordance with SEC regulations. There is no assurance, however, that the
 Financial Square Prime Obligations Fund will be successful in maintaining
 its per share value at $1.00 on a continuous basis. The per share NAVs of
 the other Underlying Funds are expected to fluctuate on a daily basis.
 
 The portfolio turnover rates of the Underlying Funds have ranged from 30% to
 315% during their most recent fiscal years. A high rate of portfolio turn-
 over (100% or more) involves correspondingly greater expenses which must be
 borne by an Underlying Fund and its shareholders. The portfolio turnover
 rate is calculated by dividing the lesser of the dollar amount of sales or
 purchases of portfolio securities by the average monthly value of an Under-
 lying Fund's portfolio securities, excluding securities having a maturity at
 the date of purchase of one year or less. There can be no assurance that the
 turnover rates of the Underlying Funds will remain within this range during
 subsequent fiscal years. Higher turnover rates may result in higher broker-
 age costs and expenses for the Underlying Funds. In addition, higher turn-
 over rates may result in higher taxable realized gains for shareholders.
 
 B. Other Risks of the Underlying Funds
 
 Risks of Investing in Small Capitalization Companies and REITs. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such
 
64
<PAGE>
 
                                                                      APPENDIX A
 
 securities. Small capitalization companies and REITs may be thinly traded
 and may have to be sold at a discount from current market prices or in small
 lots over an extended period of time. In addition, these securities are sub-
 ject to the risk that during certain periods the liquidity of particular
 issuers or industries, or all securities in these investment categories,
 will shrink or disappear suddenly and without warning as a result of adverse
 economic or market conditions, or adverse investor perceptions, whether or
 not accurate. Because of the lack of sufficient market liquidity, an Under-
 lying Fund may incur losses because it will be required to effect sales at a
 disadvantageous time and only then at a substantial drop in price. Small
 capitalization companies and REITs include "unseasoned" issuers that do not
 have an established financial history; often have limited product lines,
 markets or financial resources; may depend on or use a few key personnel for
 management; and may be susceptible to losses and risks of bankruptcy. Trans-
 action costs for these investments are often higher than those for larger
 capitalization companies. Investments in small capitalization companies and
 REITs may be more difficult to price precisely than other types of securi-
 ties because of their characteristics and lower trading volumes.
 
 
 Risks of Foreign Investments. Certain of the Underlying Funds may invest in
 foreign securities in accordance with their investment objectives and poli-
 cies. Foreign investments involve special risks that are not typically asso-
 ciated with U.S. dollar denominated or quoted securities of U.S. issuers.
 Foreign investments may be affected by changes in currency rates, changes in
 foreign or U.S. laws or restrictions applicable to such investments and
 changes in exchange control regulations (e.g., currency blockage). A decline
 in the exchange rate of the currency (i.e., weakening of the currency
 against the U.S. dollar) in which a portfolio security is quoted or denomi-
 nated relative to the U.S. dollar would reduce the value of the portfolio
 security. In addition, if the currency in which an Underlying Fund receives
 dividends, interest or other payments declines in value against the U.S.
 dollar before such income is distributed as dividends to shareholders or
 converted to U.S. dollars, the Underlying Fund may have to sell portfolio
 securities to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the Economic and Monetary Union presents unique uncer-
 tainties, including the legal treatment of certain outstanding financial
 contracts after January 1, 1999 that refer to existing currencies rather
 than the euro; the establishment and maintenance of exchange rates for cur-
 rencies being converted into the euro; the fluctuation of the euro relative
 to non-euro currencies during the transition period from January 1, 1999 to
 December 31, 2001 and beyond; whether the interest rate, tax and labor
 regimes of European countries participating in the euro will converge over
 time; and whether the conversion of the currencies of other coun-
 
                                                                              65
<PAGE>
 
 
 tries that may in the future become members of the European Union may have
 an impact on the euro. These or other factors, including political and eco-
 nomic risks, could cause market disruptions, and could adversely affect the
 value of securities held by the Underlying Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Efforts in foreign countries to remediate potential Year 2000 prob-
 lems are not as extensive as those in the United States. As a result, the
 operations of foreign markets, foreign issuers and foreign governments may
 be disrupted by the Year 2000 Problem, and the investment portfolio of an
 Underlying Fund may be adversely affected. Furthermore, with respect to cer-
 tain foreign countries, there is a possibility of nationalization, expropri-
 ation or confiscatory taxation, imposition of withholding or other taxes on
 dividend or interest payments (or, in some cases, capital gains), limita-
 tions on the removal of funds or other assets of the Underlying Funds, and
 political or social instability or diplomatic developments which could
 affect investments in those countries.
 
 Concentration of an Underlying Fund's assets in one or a few countries and
 currencies will subject a Fund to greater risks than if an Underlying Fund's
 assets were not geographically concentrated.
 
 Investment in sovereign debt obligations by certain Underlying Funds
 involves risks not present in debt obligations of corporate issuers. The
 issuer of the debt or the governmental authorities that control the repay-
 ment of the debt may be unable or unwilling to repay principal or pay inter-
 est when due in accordance with the terms of such debt, and an Underlying
 Fund may have limited recourse to compel payment in the event of a default.
 Periods of economic uncertainty may result in volatility of market prices of
 sovereign debt, and in turn an Underlying Fund's NAV, to a greater extent
 than the volatility inherent in debt obligations of U.S. issuers.

 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Underlying Funds may also invest in European
 Depository Receipts ("EDRs") or other similar instruments representing secu-
 rities of foreign issuers. ADRs represent the right to receive securities of
 foreign issuers deposited in a domestic bank or a correspondent bank. Prices
 of ADRs are quoted in U.S. dollars, and ADRs are traded in the United
 States. EDRs and GDRs are receipts
 evidencing an arrangement with a non-U.S. bank. EDRs and GDRs are not neces-
 sarily quoted in the same currency as the underlying security.
 
 Risks of Emerging Countries. Certain Underlying Funds may invest in securi-
 ties of issuers located in emerging countries. The risks of foreign invest-
 ment are heightened when the issuer is located in an emerging country.
 Emerging countries are generally located in the Asia-Pacific region, Eastern
 Europe, Latin and South America and Africa. An Underlying Fund's purchase
 and sale of portfolio securities in certain emerging countries may be con-
 strained by limitations as to daily changes in the prices of listed securi-
 ties, periodic trading or settlement volume and/or limitations on aggregate
 holdings of foreign investors. Such limitations may be computed based on the
 aggregate trading volume by or holdings of an Underlying Fund, the invest-
 ment adviser, its affiliates and their respective clients and other service
 providers. An Underlying Fund may not be able to sell securities in circum-
 stances where price, trading or settlement volume limitations have been
 reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by an Underlying Fund. The repatria-
 
                                                                              67

 tion of both investment income and capital from certain emerging countries
 is subject to restrictions such as the need for governmental consents. Due
 to restrictions on direct investment in equity securities in certain Asian
 countries, it is anticipated that an Underlying Fund may invest in such
 countries through other investment funds in such countries.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant invest-
 ment losses. Investing in emerging countries involves greater risk of loss
 due to expropriation, nationalization, confiscation of assets and property
 or the imposition of restrictions on foreign investments and on repatriation
 of capital invested.
 
 An Underlying Fund's investment in emerging countries may also be subject to
 withholding or other taxes, which may be significant and may reduce the
 return from an investment in such country to the Underlying Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve an Under-
 lying Fund's delivery of securities before receipt of payment for their
 sale. In addition, significant delays are common in certain markets in reg-
 istering the transfer of securities. Settlement or registration problems may
 make it more difficult for an Underlying Fund to value its portfolio securi-
 ties and could cause the Underlying Fund to miss attractive investment
 opportunities, to have a portion of its assets uninvested or to incur losses
 due to the failure of a counterparty to pay for securities the Underlying
 Fund has delivered or the Underlying Fund's inability to complete its con-
 tractual obligations. The creditworthiness of the local securities firms
 used by the Underlying Funds in emerging countries may not be as sound as
 the creditworthiness of firms used in more developed countries. As a result,
 the Under-

                                                                      APPENDIX A
 
 lying Fund may be subject to a greater risk of loss if a securities firm
 defaults in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make an Underlying Fund's investments in such countries less liq-
 uid and more volatile than investments in countries with more developed
 securities markets (such as the United States, Japan and most Western Euro-
 pean countries). An Underlying Fund's investments in emerging countries are
 subject to the risk that the liquidity of a particular investment, or
 investments generally, in such countries will shrink or disappear suddenly
 and without warning as a result of adverse economic, market or political
 conditions, or adverse investor perceptions, whether or not accurate.
 Because of the lack of sufficient market liquidity, an Underlying Fund
 may incur losses because it will be required to effect sales at a disadvan-
 tageous time and then only at a substantial drop in price. Investments in
 emerging countries may be more difficult to price precisely because of the
 characteristics discussed above and lower trading volumes.
 
 An Underlying Fund's use of foreign currency management techniques in emerg-
 ing countries may be limited. Due to the limited market for these instru-
 ments in emerging countries, the investment adviser does not currently
 anticipate that a significant portion of the Underlying Funds' currency
 exposure in emerging countries, if any, will be covered by such instruments.
 
 Risks of Derivative Investments. An Underlying Fund's transactions, if any,
 in options, futures, options on futures, swaps, interest rate caps, floors
 and collars, structured securities, inverse floating-rate securities,
 stripped mortgage-backed securities and currency transactions involve addi-
 tional risk of loss. Loss can result from a lack of correlation between
 changes in the value of derivative instruments and the portfolio assets (if
 any) being hedged, the potential illiquidity of the markets for derivative
 instruments, or the risks arising from margin requirements and related lev-
 erage factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the investment adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. The Underlying Funds may also invest in derivative
 investments for non-hedging purposes (that is, to seek to increase total
 return). Investing for non-hedging purposes is considered a speculative
 practice and presents even greater risk of loss.
 
 Derivative mortgage-backed securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact the cash flow and the market value of these securi-
 ties. In general, the risk of faster
 
                                                                              69
<PAGE>
 
 
 than anticipated prepayments adversely affects IOs, super floaters and pre-
 mium priced mortgage-backed securities. The risk of slower than anticipated
 prepayments generally adversely affects POs, floating-rate securities sub-
 ject to interest rate caps, support tranches and discount priced mortgage-
 backed securities. In addition, particular derivative securities may be
 leveraged such that their exposure (i.e., price sensitivity) to interest
 rate and/or prepayment risk is magnified.
 
 Some floating-rate derivative debt securities can present more complex types
 of derivative and interest rate risks. For example, range floaters are sub-
 ject to the risk that the coupon will be reduced below market rates if a
 designated interest rate floats outside of a specified interest rate band or
 collar. Dual index or yield curve floaters are subject to lower prices in
 the event of an unfavorable change in the spread between two designated
 interest rates.
 
 Risks of Illiquid Securities. The Underlying Funds may invest up to 15% (10%
 in the case of the Financial Square Prime Obligations Fund) of their net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
  .Both domestic and foreign securities that are not readily marketable
  .Certain municipal leases and participation interests
  .Certain stripped mortgage-backed securities
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain over-the-counter options
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that
   the restricted security is eligible for resale pursuant to Rule 144A
   under the Securities Act of 1933 ("144A Securities") and, therefore, is
   liquid.
 
 Investing in 144A Securities may decrease the liquidity of an Underlying
 Fund's portfolio to the extent that qualified institutional buyers become
 for a time uninterested in purchasing these restricted securities. The pur-
 chase price and subsequent valuation of restricted and illiquid securities
 normally reflect a discount, which may be significant, from the market price
 of comparable securities for which a liquid market exists.
 
 Credit Risks. Debt securities purchased by the Underlying Funds may include
 securities (including zero coupon bonds) issued by the U.S. government (and
 its agencies, instrumentalities and sponsored enterprises), foreign govern-
 ments, domestic and foreign corporations, banks and other issuers. Some of
 these fixed-income securities are described in the next section below. Fur-
 ther information is provided in the Additional Statement.

                                                                      APPENDIX A
 
 Debt securities rated BBB or higher by Standard & Poor's Ratings Group
 ("Standard & Poor's") or Baa or higher by Moody's Investors Services, Inc.
 ("Moody's") are considered "investment grade." Securities rated BBB or Baa
 are considered medium-grade obligations with speculative characteristics,
 and adverse economic conditions or changing circumstances may weaken their
 issuers' capacity to pay interest and repay principal. A security will be
 deemed to have met a rating requirement if it receives the minimum required
 rating from at least one such rating organization even though it has been
 rated below the minimum rating by one or more other rating organizations, or
 if unrated by such rating organizations, is determined by the Investment
 Adviser to be of comparable credit quality. If a security satisfies an
 Underlying Fund's minimum rating criteria at the time of purchase and is
 subsequently downgraded below such rating, the Underlying Fund will not be
 required to dispose of such security. If a downgrade occurs, the Underlying
 Fund's investment adviser will consider what action, including the sale of
 such security, is in the best interest of the Underlying Fund and its share-
 holders.
 
 Certain Underlying Funds may invest in fixed-income securities rated BB or
 Ba or below (or comparable unrated securities) which are commonly referred
 to as "junk bonds." Junk bonds are considered predominantly speculative and
 may be questionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in an Underlying Fund's portfolio is down-
 graded by a rating organization, the market price and liquidity of such
 security may be adversely affected.
 
 Non-Diversification and Geographic Risks. The Global Income Fund is regis-
 tered as a "non-diversified" fund under the Act and is, therefore, more sus-
 ceptible to adverse developments affecting any single issuer. In addition,
 the Global Income Fund, and certain other Underlying Funds, may invest more
 than 25% of their total assets in the securities of corporate and governmen-
 tal issuers located in a particular foreign country or region. Concentration
 of the investments of these or other Underlying Funds in issuers located in
 a particular country or region will subject the Underlying Fund, to a
 greater extent than if investments were less concentrated, to losses arising
 from adverse developments affecting those issuers or countries.
 
 Temporary Investment Risks. The Underlying Funds may invest a substantial
 portion, and in some cases all, of their total assets, in cash equivalents
 for temporary periods. When an Underlying Fund's assets are invested in such
 instruments, the Underlying Fund may not be achieving its investment objec-
 tive.
 
                                                                              71

 C. Investment Securities and Techniques
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Underlying Funds, including
 their associated risks. Further information is provided in the Additional
 Statement, which is available upon request.
 
 U.S. Government Securities and Related Custodial Receipts. Each Underlying
 Fund may invest in U.S. Government Securities and related custodial
 receipts. U.S. Government Securities include U.S. Treasury obligations and
 obligations issued or guaranteed by U.S. government agencies, instrumentali-
 ties or sponsored enterprises. U.S. Government Securities may be supported
 by (a) the full faith and credit of the U.S. Treasury (such as the Govern-
 ment National Mortgage Association ("Ginnie Mae")); (b) the right of the
 issuer to borrow from the U.S. Treasury (such as securities of the Student
 Loan Marketing Association); (c) the discretionary authority of the U.S.
 government to purchase certain obligations of the issuer (such as the Fed-
 eral National Mortgage Association ("Fannie Mae") and Federal Home Loan
 Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issuer.
 U.S. Government Securities also include Treasury receipts, zero coupon bonds
 and other stripped U.S. Government Securities, where the interest and prin-
 cipal components of stripped U.S. Government Securities are traded indepen-
 dently.
 
 Interests in U.S. Government Securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S. govern-
 ment.
 
 Mortgage-Backed Securities. The Underlying Funds (other than CORE U.S. Equi-
 ty, CORE Large Cap Growth, CORE Large Cap Value, CORE Small Cap Equity and
 CORE International Equity Funds (the "CORE Equity Funds")) may invest in
 these securities that represent direct or indirect participations in, or are
 collateralized by and payable from, mortgage loans secured by real property
 ("Mortgage-Backed Securities"). Mortgage-Backed Securities can be backed by
 either fixed rate mortgage loans or adjustable rate mortgage loans, and may
 be issued by either a governmental or non-governmental entity. Privately
 issued Mortgage-Backed Securities are normally structured with one or more
 types of "credit enhancement." However, these Mortgage-Backed Securities
 typically do not have the same credit standing as U.S. government guaranteed
 Mortgage-Backed Securities.
 
 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs"), and real estate mortgage
 investment conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an
 
72

                                                                      APPENDIX A
 
 investor with a specified interest in the cash flow from a pool of under-
 lying mortgages or of other Mortgage-Backed Securities. CMOs are issued in
 multiple classes. In most cases, payments of principal are applied to the
 CMO classes in the order of their respective stated maturities, so that no
 principal payments will be made on a CMO class until all other classes hav-
 ing an earlier stated maturity date are paid in full. A REMIC is a CMO that
 qualifies for special tax treatment and invests in certain mortgages princi-
 pally secured by interests in real property and other permitted investments.
 Mortgage-Backed Securities also include stripped Mortgage-Backed Securities
 ("SMBS"), which are derivative multiple class Mortgage-Backed Securities.
 SMBS are usually structured with two different classes: one that receives
 100% of the interest payments and the other that receives 100% of the prin-
 cipal payments from a pool of mortgage loans. The market value of SMBS con-
 sisting entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage loans are generally higher than pre-
 vailing market yields on other Mortgage-Backed Securities because their cash
 flow patterns are more volatile and there is a greater risk that the initial
 investment will not be fully recouped.
 
 Asset-Backed Securities. The Underlying Funds (other than the CORE Equity
 Funds) may also invest in asset-backed securities. Asset-backed securities
 are securities whose principal and interest payments are collateralized by
 pools of assets such as auto loans, credit card receivables, leases,
 installment contracts and personal property. Asset-backed securities are
 often subject to more rapid repayment than their stated maturity date would
 indicate as a result of the pass-through of prepayments of principal on the
 underlying loans. During periods of declining interest rates, prepayment of
 loans underlying asset-backed securities can be expected to accelerate.
 Accordingly, an Underlying Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. Asset-backed securities present credit risks
 that are not presented by Mortgage-Backed Securities. This is because asset-
 backed securities generally do not have the benefit of a security interest
 in collateral that is comparable in quality to mortgage assets. There is the
 possibility that, in some cases, recoveries on repossessed collateral may
 not be available to support payments on these securities. In the event of a
 default, an Underlying Fund may suffer a loss if it cannot sell collateral
 quickly and receive the amount it is owed.
 
 Municipal Securities. Certain Underlying Funds may invest in securities and
 instruments issued by state and local governmental issuers. Municipal secu-
 rities consist of bonds, notes, commercial paper and other instruments (in-
 cluding participation interests in such securities) issued by or on behalf
 of states, territories and
 
                                                                              73
<PAGE>
 
 
 possessions of the United States (including the District of Columbia) and
 their political subdivisions, agencies or instrumentalities. Such securities
 may pay fixed, variable or floating rates of interest. Municipal securities
 are often issued to obtain funds for various public purposes, including the
 construction of a wide range of public facilities such as bridges, highways,
 housing, hospitals, mass transportation, schools, streets and water and
 sewer works. Other public purposes for which municipal securities may be
 issued include refunding outstanding obligations, obtaining funds for gen-
 eral operating expenses, and obtaining funds to lend to other public insti-
 tutions and facilities. Municipal securities in which the Underlying Funds
 may invest include private activity bonds, municipal leases, certificates of
 participation, pre-refunded municipal securities and auction rate securi-
 ties.
 
 Corporate and Bank Obligations; Trust Preferred Securities; Convertible
 Securities. Certain Underlying Funds may invest in corporate debt obliga-
 tions, trust preferred securities and convertible securities. Corporate debt
 obligations include bonds, notes, debentures and other obligations of U.S.
 or foreign corporations to pay interest and repay principal, and include
 securities issued by banks and other financial institutions. Banks are sub-
 ject to extensive but different governmental regulations which may limit
 both the amount and types of loans which may be made and interest rates
 which may be charged. In addition, the profitability of the banking industry
 is largely dependent upon the availability and cost of funds for the purpose
 of financing lending operations under prevailing money market conditions.
 General economic conditions as well as exposure to credit losses arising
 from possible financial difficulties of borrowers play an important part in
 the operation of this industry. A trust preferred or capital security is a
 long dated bond (for example, 30 years) with preferred features. The pre-
 ferred features are that payment of interest can be deferred for a specified
 period without initiating a default event. The securities are generally
 senior in claim to standard preferred stock but junior to other bondholders.
 
 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than nonconvertible securities of similar quali-
 ty. Convertible securities in which an Underlying Fund invests are subject
 to the same rating criteria as its other investments in fixed-income securi-
 ties. Convertible securities have both equity and fixed-income risk charac-
 teristics. Like all fixed-income securities, the value of convertible secu-
 rities is susceptible to the risk of market losses attributable to changes
 in interest rates. Generally, the market value of convertible securities
 tends to decline as interest rates increase and, conversely, to increase as
 interest rates decline. However, when the market price of the common stock
 underlying a convertible security exceeds the conversion price of the con-
 vertible security, the convertible security tends to reflect the market
 price of the under-
 
74
<PAGE>
 
                                                                      APPENDIX A
 
 lying common stock. As the market price of the underlying common stock
 declines, the convertible security, like a fixed-income security, tends to
 trade increasingly on a yield basis, and thus may not decline in price to
 the same extent as the underlying common stock.
 
 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Certain Underlying Funds may invest in zero coupon, deferred interest, pay-
 in-kind and capital appreciation bonds. These securities are issued at a
 discount from their face value because interest payments are typically post-
 poned until maturity. Pay-in-kind securities are securities that have inter-
 est payable by the delivery of additional securities.The market prices of
 these securities generally are more volatile than the market prices of
 interest-bearing securities and are likely to respond to a greater degree to
 changes in interest rates than interest-bearing securities having similar
 maturities and credit quality.
 
 Rating Criteria. Except as noted below, the Underlying Equity Funds (other
 than the CORE Equity Funds, which only invest in debt instruments that are
 cash equivalents) may invest in debt securities rated at least investment
 grade at the time of investment. Investment grade debt securities are secu-
 rities rated BBB or higher by Standard & Poor's or Baa or higher by Moody's.
 The Growth and Income, Capital Growth, Small Cap Value, International Equi-
 ty, Japanese Equity, European Equity, International Small Cap, Emerging Mar-
 kets Equity, Asia Growth and Real Estate Securities Funds may invest up to
 10%, 10%, 35%, 35%, 35%, 35%, 35%, 35%, 35% and 20%, respectively, of their
 total assets in debt securities which are rated in the lowest rating catego-
 ries by Standard & Poor's or Moody's (i.e., BB or lower by Standard & Poor's
 or Ba or lower by Moody's), including securities rated D by Moody's or Stan-
 dard & Poor's. The Mid Cap Value Fund may invest up to 10% of its total
 assets in below investment grade debt securities rated B or higher by Stan-
 dard & Poor's or Moody's. Fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) are commonly referred to as "junk bonds,"
 are considered predominately speculative and may be questionable as to prin-
 cipal and interest payments as described above.
 
 Structured Securities and Inverse Floaters. Certain Underlying Funds may
 invest in structured securities. Structured securities are securities whose
 value is determined by reference to changes in the value of specific curren-
 cies, interest rates, commodities, indices or other financial indicators
 (the "Reference") or the relative change in two or more References. The
 interest rate or the principal amount payable upon maturity or redemption
 may be increased or decreased depending upon changes in the applicable Ref-
 erence. Structured securities may be positively or negatively indexed, so
 that appreciation of the Reference may produce an increase or decrease in
 the interest rate or value of the security at maturity. In addition, changes
 in the interest rates or the value of the security at maturity may
 
                                                                              75
<PAGE>
 
 
 be a multiple of changes in the value of the Reference. Consequently, struc-
 tured securities may present a greater degree of market risk than other
 types of fixed-income securities, and may be more volatile, less liquid and
 more difficult to price accurately than less complex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.
 
 Foreign Currency Transactions. Certain Underlying Funds may, to the extent
 consistent with their investment policies, purchase or sell foreign curren-
 cies on a cash basis or through forward contracts. A forward contract
 involves an obligation to purchase or sell a specific currency at a future
 date at a price set at the time of the contract. An Underlying Fund may
 engage in foreign currency transactions for hedging purposes and to seek to
 protect against anticipated changes in future foreign currency exchange
 rates. In addition, certain Underlying Funds may also enter into such trans-
 actions to seek to increase total return, which is considered a speculative
 practice.
 
 Underlying Funds may also engage in cross-hedging by using forward contracts
 in a currency different from that in which the hedged security is denomi-
 nated or quoted if the investment adviser determines that there is a pattern
 of correlation between the two currencies. An Underlying Fund may hold for-
 eign currency received in connection with investments in foreign securities
 when, in the judgment of the investment adviser, it would be beneficial to
 convert such currency into U.S. dollars at a later date (e.g., the Invest-
 ment Adviser anticipates that the foreign currency will appreciate against
 the U.S. dollar).
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, an Underlying Fund's NAV to fluctu-
 ate. Currency exchange rates also can be affected unpredictably by the
 intervention of U.S. or foreign governments or central banks, or the failure
 to intervene, or by currency controls or political developments in the
 United States or abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts
 
76
<PAGE>
 
                                                                      APPENDIX A
 
 are not guaranteed by an exchange or clearinghouse, a default on a contract
 would deprive an Underlying Fund of unrealized profits, transaction costs,
 or the benefits of a currency hedge, or could force the Underlying Fund to
 cover its purchase or sale commitments, if any, at the current market price.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Underlying Fund may
 write (sell) covered call and put options and purchase put and call options
 on any securities in which it may invest or on any securities index com-
 prised of securities in which it may invest. An Underlying Fund that invests
 in foreign securities may also purchase and sell (write) put and call
 options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of an investment adviser to manage future price fluctua-
 tions and the degree of correlation between the options and securities (or
 currency) markets. If an investment adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in an Underlying Fund's investment portfolio, the Underlying
 Fund may incur losses that it would not otherwise incur. The use of options
 can also increase an Underlying Fund's transaction costs. Options written or
 purchased by the Underlying Funds may be traded on either U.S. or foreign
 exchanges or over-the-counter. Foreign and over-the-counter options will
 present greater possibility of loss because of their greater illiquidity and
 credit risks.
 
 Yield Curve Options. Certain Underlying Funds may enter into options on the
 yield "spread" or differential between two securities. Such transactions are
 referred to as "yield curve" options. In contrast to other types of options,
 a yield curve option is based on the difference between the yields of desig-
 nated securities rather than the prices of the individual securities, and is
 settled through cash payments. Accordingly, a yield curve option is profit-
 able to the holder if this differential widens (in the case of a call) or
 narrows (in the case of a put), regardless of whether the yields of the
 underlying securities increase or decrease.
 
 The trading of yield curve options is subject to all of the risks associated
 with the trading of other types of options. In addition, however, such
 options present a risk
 
                                                                              77

 of loss even if the yield of one of the underlying securities remains con-
 stant, or if the spread moves in a direction or to an extent which was not
 anticipated.
 
 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. Certain Underlying Funds may engage in
 futures transactions on both U.S. and foreign exchanges.
 
 Certain Underlying Funds may purchase and sell futures contracts, and pur-
 chase and write call and put options on futures contracts, in order to seek
 to increase total return or to hedge against changes in interest rates,
 securities prices or to the extent an Underlying Fund invests in foreign
 securities, currency exchange rates, or to otherwise manage their term
 structures, sector selection and durations in accordance with their invest-
 ment objectives and policies. An Underlying Fund may also enter into closing
 purchase and sale transactions with respect to such contracts and options.
 An Underlying Fund will engage in futures and related options transactions
 for bona fide hedging purposes as defined in regulations of the Commodity
 Futures Trading Commission or to seek to increase total return to the extent
 permitted by such regulations. An Underlying Fund may not purchase or sell
 futures contracts or purchase or sell related options to seek to increase
 total return, except for closing purchase or sale transactions, if immedi-
 ately thereafter the sum of the amount of initial margin deposits and premi-
 ums paid on the Underlying Fund's outstanding positions in futures and
 related options entered into for the purpose of seeking to increase total
 return would exceed 5% of the market value of the Underlying Fund's net
 assets.
 
 Futures contracts and related options present the following risks:
 .While an Underlying Fund may benefit from the use of futures and options on
  futures, unanticipated changes in interest rates, securities prices or cur-
  rency exchange rates may result in a poorer overall performance than if the
  Underlying Fund had not entered into any futures contracts or options
  transactions.
 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and an Underlying Fund may be exposed to
  additional risk of loss.

 .The loss incurred by an Underlying Fund in entering into futures contracts
  and in writing call options on futures is potentially unlimited and may
  exceed the amount of the premium received.
 .Futures markets are highly volatile and the use of futures may increase the
  volatility of an Underlying Fund's NAV.
 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to an Underlying Fund.
 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.
 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 Preferred Stock, Warrants and Rights. Certain Underlying Funds may invest in
 preferred stock, warrants and rights. Preferred stocks are securities that
 represent an ownership interest providing the holder with claims on the
 issuer's earnings and assets before common stock owners but after bond own-
 ers. Unlike debt securities, the obligations of an issuer of preferred
 stock, including dividend and other payment obligations, may not typically
 be accelerated by the holders of such preferred stock on the occurrence of
 an event of default or other non-compliance by the issuer of the preferred
 stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.
 
 Loan Participations. Certain Underlying Funds may invest in loan participa-
 tions. A loan participation is an interest in a loan to a U.S. or foreign
 company or other borrower which is administered and sold by a financial
 intermediary. Loan participation interests may take the form of a direct or
 co-lending relationship with the corporate borrower, an assignment of an
 interest in the loan by a co-lender or another participant, or a participa-
 tion in the seller's share of the loan. When the Underlying Fund acts as co-
 lender in connection with a participation interest or when it acquires cer-
 tain participation interests, the Underlying Fund will have direct recourse
 against the borrower if the borrower fails to pay scheduled principal and
 interest. In cases where the Underlying Fund lacks direct recourse, it will
 look to the agent bank to enforce appropriate credit remedies against the
 borrower. In these cases, the Underlying Fund may be subject to delays,
 expenses and risks that are greater than those that would have been involved
 if the Underlying Fund had purchased a direct obligation (such as commercial
 paper) of such borrower. Moreover, under the terms of the loan participa-
 tion, the Underlying Fund may be regarded as a creditor of the agent bank
 (rather than of the underlying
 
                                                                              79
<PAGE>
 
 
 corporate borrower), so that the Underlying Fund may also be subject to the
 risk that the agent bank may become insolvent.
 
 Real Estate Investment Trusts ("REITs"). The Real Estate Securities Fund
 expects to invest a substantial portion of its total assets in REITs, which
 are pooled investment vehicles that invest primarily in either real estate
 or real estate related loans. In addition, other Underlying Equity Funds may
 invest in REITs from time to time. The value of a REIT is affected by
 changes in the value of the properties owned by the REIT or securing mort-
 gage loans held by the REIT. REITs are dependent upon the ability of the
 REITs' managers, and are subject to heavy cash flow dependency, default by
 borrowers and the qualification of the REITs under applicable regulatory
 requirements for favorable federal income tax treatment. REITs are also sub-
 ject to risks generally associated with investments in real estate including
 possible declines in the value of real estate, general and local economic
 conditions, environmental problems and changes in interest rates. To the
 extent that assets underlying a REIT are concentrated geographically, by
 property type or in certain other respects, these risks may be heightened.
 Each Underlying Fund will indirectly bear its proportionate share of any
 expenses, including management fees, paid by a REIT in which it invests.
 
 Other Investment Companies. An Underlying Fund may invest in securities of
 other investment companies (including SPDRs and WEBs, as described below)
 subject to statutory limitations. These limitations include a prohibition on
 any Underlying Fund acquiring more than 3% of the voting shares of any other
 investment company, and a prohibition on investing more than 5% of an Under-
 lying Fund's total assets in securities of any one investment company or
 more than 10% of its total assets in securities of all investment companies.
 An Underlying Fund will indirectly bear its proportionate share of any man-
 agement fees and other expenses paid by such other investment companies.
 Such other investment companies will have investment objectives, policies
 and restrictions substantially similar to those of the Underlying Fund and
 will be subject to substantially the same risks.
 
 .Standard and Poor's Depository Receipts. The Underlying Equity Funds may,
  consistent with their investment policies, purchase Standard & Poor's
  Depository Receipts ("SPDRs"). SPDRs are securities traded on the American
  Stock Exchange (the "AMEX") that represent ownership in the SPDR Trust, a
  trust which has been established to accumulate and hold a portfolio of com-
  mon stocks that is intended to track the price performance and dividend
  yield of the S&P 500. SPDR Trust is sponsored by a subsidiary of the AMEX.
  SPDRs may be used for several reasons, including, but not limited to,
  facilitating the handling of cash flows or trading, or reducing transaction
  costs. The price movement of SPDRs may not perfectly parallel the price
  action of the S&P 500.

 .World Equity Benchmark Shares. World Equity Benchmark Shares ("WEBS") are
  shares of an investment company that invests substantially all of its
  assets in securities included in the MSCI indices for specified countries.
  WEBS are listed on the AMEX and were initially offered to the public in
  1996. The market prices of WEBS are expected to fluctuate in accordance
  with both changes in the NAVs of their underlying indices and supply and
  demand of WEBS on the AMEX. To date, WEBS have traded at relatively modest
  discounts and premiums to their NAVs. However, WEBS have a limited operat-
  ing history and information is lacking regarding the actual performance and
  trading liquidity of WEBS for extended periods or over complete market
  cycles. In addition, there is no assurance that the requirements of the
  AMEX necessary to maintain the listing of WEBS will continue to be met or
  will remain unchanged. In the event substantial market or other disruptions
  affecting WEBS should occur in the future, the liquidity and value of an
  Underlying Equity Fund's shares could also be substantially and adversely
  affected. If such disruptions were to occur, an Underlying Equity Fund
  could be required to reconsider the use of WEBS as part of its investment
  strategy.
 
 Unseasoned Companies. Certain Underlying Funds may invest in companies (in-
 cluding predecessors) which have operated less than three years, except that
 this limitation does not apply to debt securities which have been rated
 investment grade or better by at least one rating organization. The securi-
 ties of such companies may have limited liquidity, which can result in their
 being priced higher or lower than might otherwise be the case. In addition,
 investments in unseasoned companies are more speculative and entail greater
 risk than do investments in companies with an established operating record.
 
 Non-Investment Grade Fixed-Income Securities. Non-investment grade fixed-
 income securities and unrated securities of comparable credit quality (com-
 monly known as "junk bonds") are considered predominantly speculative by
 traditional investment standards. In some cases, these obligations may be
 highly speculative and have poor prospects for reaching investment grade
 standing. Non-investment grade fixed-income securities are subject to the
 increased risk of an issuer's inability to meet principal and interest obli-
 gations. These securities, also referred to as high yield securities, may be
 subject to greater price volatility due to such factors as specific corpo-
 rate developments, interest rate sensitivity, negative perceptions of the
 junk bond markets generally and less secondary market liquidity.
 
 Non-investment grade fixed-income securities are generally unsecured and are
 often subordinated to the rights of other creditors of the issuers of such
 securities. Investment by an Underlying Fund in defaulted securities poses
 additional risk of loss should nonpayment of principal and interest continue
 in respect of such securities. Even if such securities are held to maturity,
 recovery by an Underlying Fund of its initial investment and any anticipated
 income or appreciation is uncertain.
 
                                                                              81
<PAGE>
 
 
 
 Equity Swaps. Each Underlying Equity Fund may invest up to 10% of its total
 assets in equity swaps. Equity swaps allow the parties to a swap agreement
 to exchange dividend income or other components of return on an equity
 investment (for example, a group of equity securities or an index) for a
 component of return on another non-equity or equity investment.
 
 An equity swap may be used by an Underlying Fund to invest in a market with-
 out owning or taking physical custody of securities in circumstances in
 which direct investment may be restricted for legal reasons or is otherwise
 impractical. Equity swaps are derivatives and their value can be very vola-
 tile. To the extent that an investment adviser does not accurately analyze
 and predict the potential relative fluctuation of the components swapped
 with another party, an Underlying Fund may suffer a loss. The value of some
 components of an equity swap (such as the dividends on a common stock) may
 also be sensitive to changes in interest rates. Furthermore, an Underlying
 Fund may suffer a loss if the counterparty defaults.
 
 When-Issued Securities and Forward Commitments. Each Underlying Fund may
 purchase when-issued securities and make contracts to purchase or sell secu-
 rities for a fixed price at a future date beyond customary settlement time.
 When-issued securities are securities that have been authorized, but not yet
 issued. When-issued securities are purchased in order to secure what is con-
 sidered to be an advantageous price and yield to the Underlying Fund at the
 time of entering into the transaction. A forward commitment involves the
 entering into a contract to purchase or sell securities for a fixed price at
 a future date beyond the customary settlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although an Underlying Fund
 will generally purchase securities on a when-issued or forward commitment
 basis with the intention of acquiring securities for its portfolio, an
 Underlying Fund may dispose of when-issued securities or forward commitments
 prior to settlement if its investment adviser deems it appropriate.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. The Underlying Funds may enter into repurchase
 agreements with dealers in U.S. Government Securities and member banks of
 the Federal Reserve System which furnish collateral at least equal in value
 or market price to the amount of their repurchase obligation. Some Under-
 lying Funds may also enter into repurchase agreements involving certain for-
 eign government securities.

                                                                      APPENDIX A
 
 
 If the other party or "seller" defaults, an Underlying Fund might suffer a
 loss to the extent that the proceeds from the sale of the underlying securi-
 ties and other collateral held by the Underlying Fund are less than the
 repurchase price and the Underlying Fund's cost associated with delay and
 enforcement of the repurchase agreement. In addition, in the event of bank-
 ruptcy of the seller, an Underlying Fund could suffer additional losses if a
 court determines that the Underlying Fund's interest in the collateral is
 not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, an investment
 adviser will carefully consider the creditworthiness of the seller. Certain
 Underlying Funds, together with other registered investment companies having
 advisory agreements with the investment adviser or any of its affiliates,
 may transfer uninvested cash balances into a single joint account, the daily
 aggregate balance of which will be invested in one or more repurchase agree-
 ments.
 
 Lending of Portfolio Securities. Each Underlying Fund may engage in securi-
 ties lending. Securities lending involves the lending of securities owned by
 an Underlying Fund to financial institutions such as certain broker-dealers.
 The borrowers are required to secure their loans continuously with cash,
 cash equivalents, U.S. Government Securities or letters of credit in an
 amount at least equal to the market value of the securities loaned. Cash
 collateral may be invested in cash equivalents. If an investment adviser
 determines to make securities loans, the value of the securities loaned may
 not exceed 33 1/3% of the value of the total assets of an Underlying Fund
 (including the loan collateral).
 
 An Underlying Fund may lend its securities to increase its income. An Under-
 lying Fund may, however, experience delay in the recovery of its securities
 if the institution with which it has engaged in a portfolio loan transaction
 breaches its agreement with the Underlying Fund.
 
 Short Sales Against-the-Box. Certain Underlying Funds may make short sales
 against-the-box. A short sale against-the-box means that at all times when a
 short position is open the Underlying Fund will own an equal amount of secu-
 rities sold short, or securities convertible into or exchangeable for, with-
 out the payment of any further consideration, an equal amount of the securi-
 ties of the same issuer as the securities sold short.
 
 Mortgage Dollar Rolls. Certain Underlying Funds may enter into "mortgage
 dollar rolls." In mortgage dollar rolls, an Underlying Fund sells securities
 for delivery in the current month and simultaneously contracts with the same
 counterparty to repurchase substantially similar (same type, coupon and
 maturity) but not identical securities on a specified future date. During
 the roll period, the Underlying Fund loses the right to receive principal
 and interest paid on the securities sold.
 
                                                                              83
<PAGE>
 
 
 However, the Underlying Fund benefits to the extent of any difference
 between (a) the price received for the securities sold and (b) the lower
 forward price for the future purchase and/or fee income plus the interest
 earned on the cash proceeds of the securities sold. Unless the benefits of a
 mortgage dollar roll exceed the income, capital appreciation and gain or
 loss due to mortgage prepayments that would have been realized on the secu-
 rities sold as part of the roll, the use of this technique will diminish the
 Underlying Fund's performance.
 
 Successful use of mortgage dollar rolls depends upon an investment adviser's
 ability to predict correctly interest rates and mortgage prepayments. If the
 investment adviser is incorrect in its prediction, an Underlying Fund may
 experience a loss. For financial reporting and tax purposes, the Funds treat
 mortgage dollar rolls as two separate transactions: one involving the pur-
 chase of a security and a separate transaction involving a sale. The Under-
 lying Funds do not currently intend to enter into mortgage dollar rolls that
 are accounted for as a financing and do not treat them as borrowings.
 
 Borrowings and Reverse Repurchase Agreements. Each Underlying Fund can bor-
 row money from banks, and certain Underlying Funds may enter into reverse
 repurchase agreements with banks and other financial institutions in amounts
 not exceeding one-third of their total assets. Reverse repurchase agreements
 involve the sale of securities held by an Underlying Fund subject to the
 Underlying Fund's agreement to repurchase them at a mutually agreed upon
 date and price (including interest). These transactions may be entered into
 as a temporary measure for emergency purposes or to meet redemption
 requests. Reverse repurchase agreements may also be entered into when the
 investment adviser expects that the interest income to be earned from the
 investment of the transaction proceeds will be greater than the related
 interest expense. Borrowings and reverse repurchase agreements involve
 leveraging. If the securities held by an Underlying Fund decline in value
 while these transactions are outstanding, the NAV of the Underlying Fund's
 outstanding shares will decline in value by proportionately more than the
 decline in value of the securities. In addition, reverse repurchase agree-
 ments involve the risk that any interest income earned by an Underlying Fund
 (from the investment of the proceeds) will be less than the interest expense
 of the transaction, that the market value of the securities sold by an
 Underlying Fund will decline below the price the Underlying Fund is obli-
 gated to pay to repurchase the securities, and that the securities may not
 be returned to the Underlying Fund.
 
 Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Inter-
 est Rate Caps, Floors and Collars. To the extent consistent with their
 investment policies, the Underlying Funds may enter into interest rate
 swaps, mortgage swaps, credit swaps, currency swaps and interest rate caps,
 floors and collars. Interest rate

                                                                      APPENDIX A
 
 swaps involve the exchange by an Underlying Fund with another party of their
 respective commitments to pay or receive interest, such as an exchange of
 fixed-rate payments for floating rate payments. Mortgage swaps are similar
 to interest rate swaps in that they represent commitments to pay and receive
 interest. The notional principal amount, however, is tied to a reference
 pool or pools of mortgages. Credit swaps involve the receipt of floating or
 fixed rate payments in exchange for assuming potential credit losses of an
 underlying security. Credit swaps give one party to a transaction the right
 to dispose of or acquire an asset (or group of assets), or the right to
 receive or make a payment from the other party, upon the occurrence of spec-
 ified credit events. Currency swaps involve the exchange of the parties'
 respective rights to make or receive payments in specified currencies. The
 purchase of an interest rate cap entitles the purchaser, to the extent that
 a specified index exceeds a predetermined interest rate, to receive payment
 of interest on a notional principal amount from the party selling such
 interest rate cap. The purchase of an interest rate floor entitles the pur-
 chaser, to the extent that a specified index falls below a predetermined
 interest rate, to receive payments of interest on a notional principal
 amount from the party selling the interest rate floor. An interest rate col-
 lar is the combination of a cap and a floor that preserves a certain return
 within a predetermined range of interest rates.
 
 An Underlying Fund may enter into swap transactions for hedging purposes or
 to seek to increase total return. The use of interest rate, mortgage, credit
 and currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If an investment adviser is incorrect in its forecasts of market val-
 ue, interest rates and currency exchange rates, the investment performance
 of an Underlying Fund would be less favorable than it would have been if
 these investment techniques were not used.

Financial Highlights
 
 The financial highlights tables are intended to help you understand a Port-
 folio's financial performance for the past five years (or less if the Port-
 folio has been in operation for less than five years). Certain information
 reflects financial results for a single Portfolio share. The total returns
 in the table represent the rate that an investor would have earned or lost
 on an investment in a Portfolio (assuming reinvestment of all dividends and
 distributions). This information has been audited by Arthur Andersen LLP,
 whose report, along with a Portfolio's financial statements, is included in
 the Portfolio's annual report (available upon request without charge). Dur-
 ing the period shown, the Trust did not offer the Goldman Sachs Conservative
 Strategy Portfolio. Accordingly, there are no financial highlights for this
 Portfolio.

General Investment
Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser (the "Investment
 Adviser") to five asset allocation portfolios: the Conservative Strategy
 Portfolio, Balanced Strategy Portfolio (formerly, the Income Strategy Port-
 folio), Growth and Income Strategy Portfolio, Growth Strategy Portfolio and
 Aggressive Growth Strategy Portfolio (referred to as the "Portfolios" or the
 "Funds" interchangeably herein). The Portfolios are intended for investors
 who prefer to have their asset allocation decisions made by professional
 money managers. Each Portfolio seeks to achieve its objectives by investing
 in a combination of underlying funds for which Goldman Sachs now or in the
 future acts as investment adviser or principal underwriter (the "Underlying
 Funds"). Some of these Underlying Funds invest primarily in fixed-income or
 money market securities (the "Underlying Fixed-Income Funds") and other
 Underlying Funds invest primarily in equity securities (the "Underlying
 Equity Funds"). An investor may choose to invest in one or more of the Port-
 folios based on individual investment goals, risk tolerance, and financial
 circumstances.
 
 The investment objectives and policies of the Portfolios are similar to the
 investment objectives and policies of other mutual funds that the Investment
 Adviser manages. Although the objectives and policies may be similar, the
 investment results of the Portfolios may be higher or lower than the results
 of such other mutual funds. The Investment Adviser cannot guarantee, and
 makes no representation, that the investment results of similar funds will
 be comparable even though the funds have the same Investment Adviser.
 
 Goldman Sachs' Asset Allocation Investment Philosophy:
 The Investment Adviser's Quantitative Research Group uses disciplined quan-
 titative models to determine the relative attractiveness of the world's
 stock, bond and currency markets. These models use financial and economic
 variables to capture fundamental relationships that the Quantitative
 Research Group believes make sense. While the Investment Adviser's process
 is rigorous and quantitative, it also incorporates clear economic reasoning
 behind each recommendation.
 
 The Asset Allocation Investment Process involves investing a Portfolio's
 assets in other Goldman Sachs Funds within specified equity and fixed-income
 percentage ranges.
 
- --------------------------------------------------------------------------------
 
                                                                               1
<PAGE>
 
 
 Each Portfolio starts with a strategic allocation among the various asset
 classes. The Investment Adviser then tactically deviates from the strategic
 allocations based on forecasts provided by the models. The tactical process
 seeks to add value by overweighting attractive markets and underweighting
 unattractive markets. Greater deviations from the strategic allocation of a
 given Portfolio result in higher risk that the tactical allocation will
 underperform the strategic allocation. However, the Investment Adviser's
 risk control process balances the amount any asset class can be overweighted
 in seeking to achieve higher expected returns against the amount of risk
 imposed by that deviation from the strategic allocation. The Investment
 Adviser employs Goldman Sachs' proprietary Black-Litterman asset allocation
 technique in an effort to optimally balance these two goals.

Portfolio Investment Objectives and Strategies
 
 Goldman Sachs Conservative Strategy Portfolio
 
   PORTFOLIO FACTS
- --------------------------------------------------------------------------------
 
        Objective    Current income, consistent with the preservation of capi-
                     tal and secondarily the potential for capital appreciation
                  
 Investment Focus    Primarily domestic fixed-income funds (approximately 80%)
                     focusing on short-term investments and money market funds,
                     with the balance in domestic stock funds and a small allo-
                     cation to a global bond fund
                 
 Investment Style    Asset Allocation
 
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income, consistent with the preservation of cap-
 ital and secondarily also considers the potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 80% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds, with a focus on
 short-term investments including money market funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its assets in
 the Global Income Fund, Financial Square Prime Obligations Fund and CORE
 Large Cap Value Fund. It is expected that the Portfolio will invest more
 than 25% of its assets in the Short Duration Government Fund. The Portfolio
 may not invest in Underlying Equity Funds that invest principally in foreign
 equity securities.

 The Portfolio seeks long-term capital appreciation and current income.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 60% of the Portfolio's total assets
 will be allocated among Underlying Equity Funds, which are intended to pro-
 vide the capital appreciation component. Allocation to Underlying Fixed-
 Income Funds is intended to provide the income component. The Investment
 Adviser expects that the Portfolio will invest a relatively significant per-
 centage of its equity allocation in the CORE Large Cap Growth, CORE Large
 Cap Value and CORE International Equity Funds and will invest a relatively
 significant percentage of its assets in the Core Fixed Income and Global
 Income Funds.

Principal Investment Strategies
 
Each Portfolio seeks to achieve its investment objective by investing within
specified equity and fixed-income ranges among Underlying Funds. The table
below illustrates the current Underlying Equity/Fixed-Income Fund allocation
targets and ranges for each Portfolio:

The Investment Adviser will invest in particular Underlying Funds based on var-
ious criteria. Among other things, the Investment Adviser will analyze the
Underlying Funds' respective investment objectives, policies and investment
strategies in order to determine which Underlying Funds, in combination with
other Underlying Funds, are appropriate in light of a Portfolio's investment
objective.
 
Each Portfolio's turnover rate is expected not to exceed 50% annually. A Port-
folio may purchase or sell securities to: (a) accommodate purchases and sales
of its shares; (b) change the percentages of its assets invested in each of the
Underlying Funds in response to economic or market conditions; and (c) maintain
or modify the allocation of its assets among the Underlying Funds within the
percentage ranges described above.

                                                 PRINCIPAL INVESTMENT STRATEGIES
 
 
 While each Portfolio can invest in any or all of the Underlying Funds, it is
 expected that each Portfolio will normally invest in only some of the Under-
 lying Funds at any particular time. Each Portfolio's investment in any of
 the Underlying Funds may, and in some cases is expected to, exceed 25% of
 such Portfolio's total assets.
 
 THE PARTICULAR UNDERLYING FUNDS IN WHICH EACH PORTFOLIO MAY INVEST, THE
 EQUITY/FIXED-INCOME TARGETS AND RANGES AND THE INVESTMENTS IN EACH UNDER-
 LYING FUND MAY BE CHANGED FROM TIME TO TIME WITHOUT SHAREHOLDER APPROVAL.
 
 In addition, each Portfolio's investment objectives and all policies not
 specifically designated as fundamental in this Prospectus or the Statement
 of Additional Information (the "Additional Statement") are non-fundamental
 and may be changed without shareholder approval. If there is a change in a
 Portfolio's investment objective, you should consider whether that Portfolio
 remains an appropriate investment in light of your then current financial
 position and needs.

Principal Risks of the Portfolios
 
Loss of money is a risk of investing in each Portfolio. An investment in a
Portfolio is not a deposit of any bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other governmental agency. While
the Portfolios offer a greater level of diversification than many other types
of mutual funds, a single Portfolio may not provide a complete investment pro-
gram for an investor. The following summarizes important risks that apply to
the Portfolios and may result in a loss of your investment. There can be no
assurance that a Portfolio will achieve its investment objective.
 
 .Investing in the Underlying Funds--The investments of each Portfolio are
 concentrated in the Underlying Funds, and each Portfolio's investment
 performance is directly related to the investment performance of the
 Underlying Funds held by it. The ability of each Portfolio to meet its
 investment objective is directly related to the ability of the Underlying
 Funds to meet their objectives as well as the allocation among those
 Underlying Funds by the Investment Adviser. The value of the Underlying Funds'
 investments, and the net asset values ("NAV") of the shares of both the
 Portfolios and the Underlying Funds, will fluctuate in response to various
 market and economic factors related to the equity and fixed-income markets, as
 well as the financial condition and prospects of issuers in which the
 Underlying Funds invest. There can be no assurance that the investment
 objective of any Portfolio or any Underlying Fund will be achieved.
 .Investments of the Underlying Funds--Because the Portfolios invest in the
 Underlying Funds, the Portfolios' shareholders will be affected by the
 investment policies of the Underlying Funds in direct proportion to the amount
 of assets the Portfolios allocate to those Funds. Each Portfolio may invest in
 Underlying Funds that in turn invest in small capitalization companies and
 foreign issuers and thus are subject to additional risks, including changes in
 foreign currency exchange rates and political risk. Foreign investments may
 include securities of issuers located in emerging countries in Asia, Latin
 America, Eastern Europe and Africa. Each Portfolio may also invest in
 Underlying Funds that in turn invest in non-investment grade fixed-income
 securities ("junk bonds"), which are considered speculative by traditional
 standards. In addition, the Underlying Funds may purchase derivative
 securities; enter into forward currency transactions; lend their portfolio
 securities; enter into futures contracts and options transactions; purchase
 zero coupon bonds and payment-in-kind bonds; purchase securities issued by
 real estate investment trusts ("REITs") and other issuers in the real estate
 industry; purchase restricted and illiquid securities; purchase securities on
 a when-issued or delayed delivery basis; enter into repurchase agreements;
 borrow money; and

 engage in various other investment practices. The risks presented by these
 investment practices are discussed in Appendix A to this Prospectus and the
 Additional Statement.
 .Affiliated Persons--In managing the Portfolios, the Investment Adviser will
 have the authority to select and substitute Underlying Funds. The Investment
 Adviser is subject to conflicts of interest in allocating Portfolio assets
 among the various Underlying Funds both because the fees payable to it and/or
 its affiliates by some Underlying Funds are higher than the fees payable by
 other Underlying Funds and because the Investment Adviser and its affiliates
 are also responsible for managing the Underlying Funds. The Trustees and
 officers of the Goldman Sachs Trust may also have conflicting interests in
 fulfilling their fiduciary duties to both the Portfolios and the Underlying
 Funds.
 .Expenses--You may invest in the Underlying Funds directly. By investing in the
 Underlying Funds indirectly through a Portfolio, you will incur not only a
 proportionate share of the expenses of the Underlying Funds held by the
 Portfolio (including operating costs and investment management fees), but also
 expenses of the Portfolio.
 .Temporary Investments--Although the Portfolios normally seek to remain
 substantially invested in the Underlying Funds, each Portfolio may invest a
 portion of its assets in high-quality, short-term debt obligations (including
 commercial paper, certificates of deposit, bankers' acceptances, repurchase
 agreements, debt obligations backed by the full faith and credit of the U.S.
 government and demand and time deposits of domestic and foreign banks and
 savings and loan associations) to maintain liquidity, to meet shareholder
 redemptions and for other short-term cash needs. Also, there may be times
 when, in the opinion of the Investment Adviser, abnormal market or economic
 conditions warrant that, for temporary defensive purposes, a Portfolio may
 invest without limitation in short-term obligations. When a Portfolio's assets
 are invested in such investments, the Portfolio may not be achieving its
 investment objective.
 .Other Risks--Each Portfolio is subject to other risks, such as (1) the risk
 that the operations of a Portfolio and the Underlying Funds in which it
 invests, or the value of their securities, will be disrupted by the "Year 2000
 Problem;" (2) the risk that a Portfolio will not be able to pay redemption
 proceeds within the period stated in this Prospectus because of unusual market
 conditions, an unusually high volume of redemption requests or other reasons
 (Liquidity Risk); or (3) the risk that a strategy used by the Investment
 Adviser may fail to produce the intended results (Management Risk).

 invest in other Underlying Funds not listed below that may become available
 for investment in the future at the discretion of the Investment Adviser
 without shareholder approval. Additional information regarding the invest-
 ment practices of the Underlying Funds is provided in Appendix A to this
 Prospectus and the Additional Statement. No offer is made in this Prospectus
 of any of the Underlying Funds.

Principal Risks of the Underlying Funds
 
The following summarizes important risks that apply to the Underlying Funds and
may result in a loss of your investment in a Portfolio. There can be no assur-
ance that an Underlying Fund will achieve its investment objective.
 
Risks That Apply To All Underlying Funds:
 
 .Interest Rate Risk--The risk that when interest rates increase, fixed-income
 securities held by an Underlying Fund will decline in value. Long-term fixed-
 income securities will normally have more price volatility because of this
 risk than short-term securities.
 .Credit/Default Risk--The risk that an issuer of fixed-income securities held
 by an Underlying Fund (which may have low credit ratings) may default on its
 obligation to pay interest and repay principal.
 .Market Risk--The risk that the value of the securities in which an Underlying
 Fund invests may go up or down in response to the prospects of individual com-
 panies and/or general economic conditions. Price changes may be temporary or
 last for extended periods.
 .Derivatives Risk--The risk that loss may result from an Underlying Fund's
 investments in options, futures, swaps, structured securities and other deriv-
 ative instruments. These instruments may be leveraged so that small changes
 may produce disproportionate losses to an Underlying Fund.
 .Foreign Risks--The risk that when an Underlying Fund invests in foreign securi-
 ties, it will be subject to the risks of loss not typically associated with
 domestic issuers. Loss may result because of less foreign government regula-
 tion, less public information and less economic, political and social stabili-
 ty. Loss may also result from the imposition of exchange controls, confisca-
 tions and other government restrictions. The Underlying Funds will also be
 subject to the risk of negative foreign currency rate fluctuations. Foreign
 risks will normally be greatest when an Underlying Fund invests in issuers
 located in emerging countries.
 .Management Risk--The risk that a strategy used by an investment adviser to the
 Underlying Funds may fail to produce the intended results.
 .Liquidity Risk--The risk that an Underlying Fund will not be able to pay
 redemption proceeds within the time period stated in this Prospectus, because
 of unusual market conditions, an unusually high volume of redemption requests,
 or other reasons. Underlying Funds that invest in non-investment grade fixed-
 income securities, small capitalization stocks, REITs or emerging country
 issuers will be especially subject to the risk that during certain periods the
 liquidity of particular issuers or industries, or all securities within these
 investment categories, will
 
                                                                              17
<PAGE>
 
 shrink or disappear suddenly and without warning as a result of adverse eco-
 nomic, market or political events, or adverse investor perceptions whether or
 not accurate.
 .Other Risks--Each Underlying Fund is subject to other risks, such as the risk
 that its operations, or the value of its portfolio securities, will be dis-
 rupted by the "Year 2000 Problem."
 
Risks That Apply Primarily To The Underlying Fixed-Income Funds:
 
 .Call Risk--The risk that an issuer will exercise its right to pay principal on
 an obligation held by an Underlying Fund (such as a Mortgage-Backed Security)
 earlier than expected. This may happen when there is a decline in interest
 rates. Under these circumstances, an Underlying Fund may be unable to recoup
 all of its initial investment and will also suffer from having to reinvest in
 lower yielding securities.
 .Extension Risk--The risk that an issuer will exercise its right to pay princi-
 pal on an obligation held by an Underlying Fund (such as a Mortgage-Backed
 Security) later than expected. This may happen when there is a rise in inter-
 est rates. Under these circumstances, the value of an obligation will
 decrease, and an Underlying Fund will also suffer from the inability to invest
 in higher yielding securities.
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risk That Applies Primarily To The Underlying Equity Funds:
 
 .Stock Risk--The risk that stock prices have historically risen and fallen in
 periodic cycles. As of the date of this Prospectus, U.S. stock markets and
 certain foreign stock markets were trading at or close to record high levels.
 There is no guarantee that such levels will continue.
 
Risks That Are Particularly Important For Specific Underlying Funds:
 
 .Country Risks--The European Equity Fund invests primarily in equity securities
 of European companies. The Japanese Equity Fund invests primarily in equity
 securities of Japanese companies. The Asia Growth Fund invests primarily in
 equity securities of Asian issuers. The Global Income Fund is non-diversified.
 The Global Income Fund may invest more than 25% of its total assets in the
 securities of corporate and governmental issuers located in each of Canada,
 Germany, Japan, and the United Kingdom as well as in the securities of U.S.

                                         PRINCIPAL RISKS OF THE UNDERLYING FUNDS
 
 issuers. Concentration of the investments of these or other Underlying Funds
 in issuers located in a particular country or region will subject the Under-
 lying Fund, to a greater extent than if investments were less concentrated, to
 losses arising from adverse developments affecting those issuers or countries.
 .Emerging Countries Risk--Certain Underlying Funds will invest in emerging
 country securities. The securities markets of Asian, Latin American, Eastern
 European, African and other emerging countries are less liquid, are especially
 subject to greater price volatility, have smaller market capitalizations, have
 less government regulation and are not subject to as extensive and frequent
 accounting, financial and other reporting requirements as the securities mar-
 kets of more developed countries. Further, investment in equity securities of
 issuers located in Russia and certain other emerging countries involves risk of
 loss resulting from problems in share registration and custody and substan-tial
 economic and political disruptions. These risks are not normally associ-ated
 with investments in more developed countries.
 .Small Cap Stock and REIT Risks--Certain Underlying Funds will invest in small
 cap stocks and REITs. The securities of small capitalization companies and
 REITs involve greater risks than those associated with larger, more established
 com-panies and may be subject to more abrupt or erratic price movements. 
 Securities of such issuers may lack sufficient market liquidity to enable an
 Under-lying Fund to effect sales at an advantageous time or without a
 substantial drop in price.
 ."Junk Bond" Risk--Certain Underlying Funds will invest in non-investment grade
 fixed-income securities (commonly known as "junk bonds") that are considered
 predominantly speculative by traditional investment standards. Non-investment
 grade fixed-income securities and unrated securities of comparable credit
 quality are subject to the increased risk of an issuer's inability to meet
 principal and interest obligations. These securities may be subject to greater
 price volatility due to such factors as specific corporate developments,
 interest rate sensitivity, negative perceptions of the junk bond markets gen-
 erally and less secondary market liquidity.
 
More information about the portfolio securities and investment techniques of
the Underlying Funds, and their associated risks, is provided in Appendix A.
You should consider the investment risks discussed in this section and in
Appendix A. Both are important to your investment choice.

Portfolio Performance
 
 HOW THE PORTFOLIOS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Portfolio by showing: (a) changes in the performance of a Portfo-
 lio's Institutional Shares from year to year; and (b) how the average annual
 returns of a Portfolio's Institutional Shares compare to those of broad-
 based securities market indices. The bar chart and table assume reinvestment
 of dividends and distributions. A Portfolio's past performance is not neces-
 sarily an indication of how the Portfolio will perform in the future. Per-
 formance reflects expense limitations in effect. If expense limitations were
 not in place, a Portfolio's performance would have been reduced. The Conser-
 vative Strategy Portfolio did not commence operations until February 8,
 1999. Since the Portfolio has less than one calendar year's performance, no
 performance information is provided in this section.

Portfolio Fees and Expenses continued
 
 
/1/The Portfolios' annual operating expenses have been restated to reflect cur-
rent fees, except for the Conservative Strategy Portfolio, whose expenses are
estimated for the current fiscal year. "Underlying Fund Expenses" for each
Portfolio are based upon the strategic allocation of each Portfolio's invest-
ment in the Underlying Funds and upon the actual total operating expenses of
the Underlying Funds (including any current waivers and expense limitations of
the Underlying Funds). Actual Underlying Fund expenses incurred by each Portfo-
lio may vary with changes in the allocation of each Portfolio's assets among
the Underlying Funds and with other events that directly affect the expenses of
the Underlying Funds.
/2/The Investment Adviser has voluntarily agreed not to impose a portion of the
management fee on the Portfolios equal to 0.20% of the Portfolios' average
daily net assets. As a result of fee waivers, current management fees of the
Portfolios are 0.15% of each Portfolio's average daily net assets. The waivers
may be terminated at any time at the option of the Investment Adviser.
/3/"Other Expenses" include transfer agency fees equal to 0.04% of the average
daily net assets of each Portfolio's Institutional Shares plus all other ordi-
nary expenses not detailed above. The Investment Adviser has voluntarily agreed
to reduce or limit "Other Expenses" (excluding management fees, transfer agency
fees, taxes, interest and brokerage fees and litigation, indemnification and
other extraordinary expenses) to 0.00% of each Portfolio's average daily net
assets.

Example
 
 
The following Example is intended to help you compare the cost of investing in
a Portfolio (without the waivers and expense limitations) with the cost of
investing in other mutual funds. The Example assumes that you invest $10,000 in
Institutional Shares of a Portfolio for the time periods indicated and then
redeem all of your shares at the end of those periods. The Example also assumes
that your investment has a 5% return each year and that a Portfolio's operating
expenses remain the same. Although your actual costs may be higher or lower,
based on these assumptions your costs would be:

Institutions that invest in Institutional Shares on behalf of their customers
may charge other fees directly to their customer accounts in connection with
their investments. You should contact your institution for information regard-
ing such charges. Such fees, if any, may affect the return such customers real-
ize with respect to their investments.
 
Certain institutions that invest in Institutional Shares on behalf of their
customers may receive other compensation in connection with the sale and dis-
tribution of such shares or for services to their customers' accounts and/or
the Portfolios. For additional information regarding such compensation, see
"Shareholder Guide" in the Prospectus and "Other Information" in the Statement
of Additional Information ("Additional Statement").

 The difference, if any, between the stated fees and the actual fees paid by
 the Portfolios reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
                                                                              31

In addition, each Portfolio, as a shareholder in the Underlying Funds, will
indirectly bear a proportionate share of any investment management fees and
other expenses paid by the Underlying Funds. The following chart shows the cur-
rent total net operating expense ratios (management fee plus other operating
expenses) of Institutional Shares of each Underlying Fund in which the Portfo-
lios may invest after applicable fee waivers and expense limitations. In addi-
tion, the following chart shows the contractual investment management fees pay-
able to the investment adviser and its affiliates by the Underlying Funds (in
each case as an annualized percentage of a Fund's average net assets). Absent
voluntary fee waivers and/or expense reimbursements, which may be discontinued
at any time, the total operating expense ratios of certain Underlying Funds
would be higher.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Portfolio's shares.
 Goldman Sachs, 4900 Sears Tower, Chicago, Illinois, 60606-6372, also serves
 as each Portfolio's transfer agent (the "Transfer Agent") and, as such, per-
 forms various shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Underlying Funds or Portfolios. Goldman Sachs reserves
 the right to redeem at any time some or all of the shares acquired for its
 own amount.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to an Underlying Fund or limit an Underlying Fund's investment activities.
 Goldman Sachs and its affiliates engage in proprietary trading and advise
 accounts and funds which have investment objectives similar to those of the
 Underlying Funds and/or which engage in and compete for transactions in the
 same types of securities, currencies and instruments as the Underlying
 Funds. Goldman Sachs and its affiliates will not have any obligation to make
 available any information regarding their proprietary activities or strate-
 gies, or the activities or strategies used for other accounts managed by
 them, for the benefit of the management of the Underlying Funds.
 
34
<PAGE>
 
 
 The results of an Underlying Fund's investment activities, therefore, may
 differ from those of Goldman Sachs and its affiliates, and it is possible
 that an Underlying Fund could sustain losses during periods in which Goldman
 Sachs and its affiliates and other accounts achieve significant profits on
 their trading for proprietary or other accounts. In addition, the Underlying
 Funds may, from time to time, enter into transactions in which other clients
 of Goldman Sachs have an adverse interest. An Underlying Fund's activities
 may be limited because of regulatory restrictions applicable to Goldman
 Sachs and its affiliates, and/or their internal policies designed to comply
 with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Portfolios and the Underlying Funds could be
 adversely affected in their ability to process securities trades, price
 securities, provide shareholder account services and otherwise conduct nor-
 mal business operations if the Investment Adviser or other service providers
 do not adequately address this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .   The Investment Adviser has established a dedicated group to analyze
     these issues and to implement the systems modifications necessary to
     prepare for the Year 2000 Problem.
 .   The Investment Adviser has sought assurances from the Portfolios' other
     service providers that they are taking the steps necessary so that they
     do not experience Year 2000 Problems, and the Investment Adviser will
     continue to monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Portfolios at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the
 
                                                                              35

 issuers of securities held by the Portfolios. The Investment Adviser may
 obtain such Year 2000 information from various sources which the Investment
 Adviser believes to be reliable, including the issuers' public regulatory
 filings. However, the Investment Adviser is not in a position to verify the
 accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Portfolios' other service providers will be
 sufficient to avoid any adverse effect on the Portfolios due to the Year
 2000 Problem.

Dividends
 
Each Fund pays dividends from its net investment income and distributions from
net realized capital gains. You may choose to have dividends and distributions
paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund. Spe-
 cial restrictions may apply for certain ILA Portfolios. See the Additional
 Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from net capital gains
are declared and paid as follows:

From time to time a portion of a Portfolio's dividends may constitute a return
of capital.
 
At the time of an investor's purchase of shares of a Portfolio, a portion of
the NAV per share may be represented by undistributed income or realized or
unrealized appreciation of the Portfolio's portfolio securities. Therefore,
subsequent distributions on such shares from such income or realized apprecia-
tion may be taxable to the investor even if the NAV of the shares is, as a
result of the distributions, reduced below the cost of such shares and the dis-
tributions (or portions thereof) represent a return of a portion of the pur-
chase price.
 
                                                                              37

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Institutional
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Institutional Shares Of The Funds?
 You may purchase Institutional Shares on any business day at their net asset
 value ("NAV") next determined after receipt of an order. No sales load is
 charged. You should place an order with Goldman Sachs at 1-800-621-2550 and
 either:
 .Wire federal funds to The Northern Trust Company ("Northern"), as
  subcustodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian) on the next business day; or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Northern;
  or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 In order to make an initial investment in a Fund, you must furnish to the
 Fund or Goldman Sachs the Account Application attached to this Prospectus.
 Purchases of Institutional Shares must be settled within three business days
 of receipt of a complete purchase order.
 
 How Do I Purchase Shares Through A Financial Institution?
 Certain institutions (including banks, trust companies, brokers and invest-
 ment advisers) that provide recordkeeping, reporting and processing services
 to their customers may be authorized to accept, on behalf of Goldman Sachs
 Trust (the "Trust"), purchase, redemption and exchange orders placed by or
 on behalf of their customers, and may designate other intermediaries to
 accept such orders, if approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized institution or intermediary on a busi-
  ness day, and the order will be priced at the Fund's NAV next determined
  after such acceptance.
 .Authorized institutions and intermediaries will be responsible for trans-
  mitting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 You should contact your institution or intermediary to learn whether it is
 authorized to accept orders for the Trust.

 These institutions may receive payments from the Funds or Goldman Sachs for
 the services provided by them with respect to the Funds' Institutional
 Shares. These payments may be in addition to other payments borne by the
 Funds.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to certain institutions and other persons in
 connection with the sale, distribution and/or servicing of shares of the
 Funds and other Goldman Sachs Funds. Subject to applicable NASD regulations,
 the Investment Adviser, Distributor and/or their affiliates may also con-
 tribute to various cash and non-cash incentive arrangements to promote the
 sale of shares. This additional compensation can vary among such institu-
 tions depending upon such factors as the amounts their customers have
 invested (or may invest) in particular Goldman Sachs Funds, the particular
 program involved, or the amount of reimbursable expenses. Additional compen-
 sation based on sales may, but is currently not expected to, exceed 0.50%
 (annualized) of the amount invested.
 
 In addition to Institutional Shares, each Fund also offers other classes of
 shares to investors. These other share classes are subject to different fees
 and expenses (which affect performance), have different minimum investment
 requirements and are entitled to different services than Institutional
 Shares. Information regarding these other share classes may be obtained from
 your sales representative or from Goldman Sachs by calling the number on the
 back cover of this Prospectus.

 The minimum investment requirement may be waived for current and former
 officers, partners, directors or employees of Goldman Sachs or any of its
 affiliates or for other investors at the discretion of the Trust's officers.
 No minimum amount is required for subsequent investments.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment amounts.
 .Reject or restrict any purchase or exchange orders by a particular pur-
  chaser (or group of related purchasers). This may occur, for example, when
  a pattern of frequent purchases, sales or exchanges of Institutional Shares
  of a Fund is evident, or if purchases, sales or exchanges are, or a subse-
  quent abrupt redemption might be, of a size that would disrupt the manage-
  ment of a Fund.

<PAGE>
 
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Institutional
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                        (Value of Assets of the Class)
                         - (Liabilities of the Class)
             NAV = _________________________________________
                   Number of Outstanding Shares of the Class
 
 
 The Funds' investments are valued based on market quotations or, if accurate
 quotations are not readily available, the fair value of the Fund's invest-
 ments may be determined in good faith under procedures established by the
 Trustees.
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will not be priced on any day
  the New York Stock Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form.
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if
 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 In addition, the impact of events that occur after the publication of market
 quotations used by a Fund to price its securities but before the close of
 regular trading on the New York Stock Exchange will normally not be
 reflected in a Fund's next determined NAV unless the Trust, in its discre-
 tion, makes an adjustment in light of the nature and materiality of the
 event, its effect on Fund operations and other relevant factors.
 
                                                                              41

 HOW TO SELL SHARES
 
 
 How Can I Sell Institutional Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Generally, each Fund will redeem its Institu-
 tional Shares upon request on any business day at their NAV next determined
 after receipt of such request in proper form. You may request that redemp-
 tion proceeds be sent to you by check or by wire (if the wire instructions
 are on record). Redemptions may be requested in writing or by telephone.

</TABLE>
 Certain institutions and intermediaries are authorized to accept redemption
 requests on behalf of the Funds as described under "How Do I Purchase Shares
 Through A Financial Institution?"
 
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.

                                                               SHAREHOLDER GUIDE
 
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: You may arrange for your redemption proceeds to be wired as federal
 funds to the bank account designated in your Account Application. The fol-
 lowing general policies govern wiring redemption proceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If you are selling shares you recently paid for by
  check, the Fund will pay you when your check has cleared, which may take up
  to 15 days. If the Federal Reserve Bank is closed on the day that the
  redemption proceeds would ordinarily be wired, wiring the redemption pro-
  ceeds may be delayed one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  account application to the Transfer Agent.
 .Neither the Trust, Goldman Sachs nor any other institution assumes any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
 
 By Check: You may elect in writing to receive your redemption proceeds by
 check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of a properly executed redemp-
 tion request. If you are selling shares you recently paid for by check, the
 Fund will pay you when your check has cleared, which may take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Institutions (including banks, trust companies, brokers and investment
  advisers) are responsible for the timely transmittal of redemption requests
  by their customers to the Transfer Agent. In order to facilitate the timely
  transmittal of redemption requests, these institutions may set times by
  which they must receive
 
                                                                              43

  redemption requests. These institutions may also require additional docu-
  mentation from you.
 
 The Trust reserves the right to:
 .Redeem your shares if your account balance falls below $50 as a result of
  earlier redemptions. The Funds will not redeem your shares on this basis if
  the value of your account falls below the minimum account balance solely as
  a result of market conditions. The Fund will give you 60 days' prior writ-
  ten notice to allow you to purchase sufficient additional shares of the
  Fund in order to avoid such redemption.
 .Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange Institutional Shares of a Fund at NAV for Institutional
 Shares of any other Goldman Sachs Fund. The exchange privilege may be mate-
 rially modified or withdrawn at any time upon 60 days' written notice to
 you.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.

 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types of Reports Will I Be Sent Regarding Investments In Institutional
 Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-621-2550. You will also be provided with a
 printed confirmation for each transaction in your account and a monthly
 account statement. The Funds do not generally provide sub-accounting servic-
 es.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Portfolio distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Portfolio's net investment income, certain net real-
 ized foreign exchange gains and net short-term capital gains. They are tax-
 able as long-term capital gains to the extent they are attributable to the
 Portfolio's excess of net long-term capital gains (including long-term capi-
 tal gain distributions received from Underlying Fund investments) over net
 short-term capital losses. The tax status of any distribution is the same
 regardless of how long you have been in the Portfolio and whether you rein-
 vest in additional shares or take the distribution as cash. Certain distri-
 butions paid by a Portfolio in January of a given year may be taxable to
 shareholders as if received the prior December 31. The tax status and
 amounts of the distributions for each calendar year will be detailed in your
 annual tax statement from the Portfolio.
 
 The REIT investments of the underlying Real Estate Securities Fund often do
 not provide complete tax information to the Fund until after the calendar
 year-end. Consequently, because of the delay, it may be necessary for the
 Asset Allocation Portfolios to request permission to extend the deadline for
 issuance of Forms 1099-DIV beyond January 31.
 
 A Portfolio's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Portfolio receives from Underlying
 Fund investments may be eligible, in the hands of the corporate sharehold-
 ers, for the corporate dividends-received deduction, subject to certain
 holding period requirements and debt financing limitations.
 
 There are certain tax requirements that all Portfolios must follow in order
 to avoid federal taxation. In its efforts to adhere to these requirements,
 the Portfolios may have to limit their investment activity in some types of
 instruments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Portfolio shares may generate a tax liability (un-
 less your investment is in an IRA or other tax-advantaged account). Depend-
 ing upon the purchase or sale price of the shares you sell or exchange, you
 may have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Portfolio, based on
 the differ-

                                                                        TAXATION
 
 ence between your tax basis in the shares and the amount you receive for
 them. (To aid in computing your tax basis, you generally should retain your
 account statements for the periods that you hold shares.) Any loss recog-
 nized on shares held for six months or less will be treated as a long-term
 capital loss to the extent of any capital gain dividends that were received
 with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from a Portfolio or on the value of the
 shares held by you. More tax information is provided in the Additional
 Statement. You should also consult your own tax adviser for information
 regarding all tax consequences applicable to your investments in the Portfo-
 lios.

Appendix A
Additional Information on the Underlying Funds
 
 This Appendix provides further information on certain types of securities
 and techniques that may be used by the Underlying Funds, including their
 associated risks. Additional information is provided in the Additional
 Statement, which is available upon request, and in the prospectuses of the
 Underlying Funds.
 
 The Underlying Equity Funds invest primarily in common stocks and other
 equity securities, including preferred stocks, interests in real estate
 investment trusts, convertible debt obligations, convertible preferred
 stocks, equity interests in trusts, partnerships, joint ventures, limited
 liability companies and similar enterprises, warrants and stock purchase
 rights ("equity securities"). The Underlying Fixed-Income Funds invest pri-
 marily in fixed-income securities, including senior and subordinated corpo-
 rate debt obligations (such as bonds, debentures, notes and commercial
 paper), convertible and non-convertible corporate debt obligations, loan
 participations and preferred stock.
 
 The Short-Duration Government and Adjustable Rate Government Funds invest in
 U.S. Government Securities and related repurchase agreements, and neither of
 these Funds, the Government Income Fund nor the Financial Square Prime
 Obligations Fund makes foreign investments. The investments of the Financial
 Square Prime Obligations Fund are limited by SEC regulations applicable to
 money market funds as described in its prospectus, and do not include many of
 the types of investments discussed below that are permitted for the other
 Underlying Funds. With these exceptions, and the further exceptions noted
 below, the following description applies generally to the Underlying Funds.
 
 A. General Risks of the Underlying Funds
 
 The Underlying Equity Funds will be subject to the risks associated with
 common stocks and other equity securities. In general, stock values fluctu-
 ate in response to the activities of individual companies and in response to
 general market and economic conditions. Accordingly, the value of the stocks
 that an Underlying Fund holds may decline over short or extended periods.
 The stock markets tend to be cyclical, with periods when stock prices gener-
 ally rise and periods when prices generally decline.
 
 The Underlying Fixed-Income Funds will be subject to the risks associated
 with fixed-income securities. These risks include interest rate risk, credit
 risk and call/extension risk. In general, interest rate risk involves the
 risk that when interest
 
48
<PAGE>
 
                                                                      APPENDIX A
 
 rates decline, the market value of fixed-income securities tends to
 increase. Conversely, when interest rates increase, the market value of
 fixed-income securities tends to decline. Credit risk involves the risk that
 an issuer could default on its obligations, and an Underlying Fund will not
 recover its investment. Call risk and extension risk are normally present in
 adjustable rate mortgage loans ("ARMs"), mortgage-backed securities and
 asset-backed securities. For example, homeowners have the option to prepay
 their mortgages. Therefore, the duration of a security backed by home mort-
 gages can either shorten (call risk) or lengthen (extension risk). In gener-
 al, if interest rates on new mortgage loans fall sufficiently below the
 interest rates on existing outstanding mortgage loans, the rate of prepay-
 ment would be expected to increase. Conversely, if mortgage loan interest
 rates rise above the interest rates on existing outstanding mortgage loans,
 the rate of prepayment would be expected to decrease. In either case, a
 change in the prepayment rate can result in losses to investors.
 
 The Financial Square Prime Obligations Fund attempts to maintain a stable
 NAV of $1.00 per share and values its assets using the amortized cost method
 in accordance with SEC regulations. There is no assurance, however, that the
 Financial Square Prime Obligations Fund will be successful in maintaining
 its per share value at $1.00 on a continuous basis. The per share NAVs of
 the other Underlying Funds are expected to fluctuate on a daily basis.
 
 The portfolio turnover rates of the Underlying Funds have ranged from 30% to
 315% during their most recent fiscal years. A high rate of portfolio turn-
 over (100% or more) involves correspondingly greater expenses which must be
 borne by an Underlying Fund and its shareholders. The portfolio turnover
 rate is calculated by dividing the lesser of the dollar amount of sales or
 purchases of portfolio securities by the average monthly value of an Under-
 lying Fund's portfolio securities, excluding securities having a maturity at
 the date of purchase of one year or less. There can be no assurance that the
 turnover rates of the Underlying Funds will remain within this range during
 subsequent fiscal years. Higher turnover rates may result in higher broker-
 age costs and expenses for the Underlying Funds. In addition, higher turn-
 over rates may result in higher taxable realized gains for shareholders.
 
 B. Other Risks of the Underlying Funds
 
 Risks of Investing in Small Capitalization Companies and REITs. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such
 
                                                                              49
<PAGE>
 
 
 securities. Small capitalization companies and REITs may be thinly traded
 and may have to be sold at a discount from current market prices or in small
 lots over an extended period of time. In addition, these securities are sub-
 ject to the risk that during certain periods the liquidity of particular
 issuers or industries, or all securities in these investment categories,
 will shrink or disappear suddenly and without warning as a result of adverse
 economic or market conditions, or adverse investor perceptions, whether or
 not accurate. Because of the lack of sufficient market liquidity, an Under-
 lying Fund may incur losses because it will be required to effect sales at a
 disadvantageous time and only then at a substantial drop in price. Small
 capitalization companies and REITs include "unseasoned" issuers that do not
 have an established financial history; often have limited product lines,
 markets or financial resources; may depend on or use a few key personnel for
 management; and may be susceptible to losses and risks of bankruptcy. Trans-
 action costs for these investments are often higher than those for larger
 capitalization companies. Investments in small capitalization companies and
 REITs may be more difficult to price precisely than other types of securi-
 ties because of their characteristics and lower trading volumes.
 
 
 Risks of Foreign Investments. Certain of the Underlying Funds may invest in
 foreign securities in accordance with their investment objectives and poli-
 cies. Foreign investments involve special risks that are not typically asso-
 ciated with U.S. dollar denominated or quoted securities of U.S. issuers.
 Foreign investments may be affected by changes in currency rates, changes in
 foreign or U.S. laws or restrictions applicable to such investments and
 changes in exchange control regulations (e.g., currency blockage). A decline
 in the exchange rate of the currency (i.e., weakening of the currency
 against the U.S. dollar) in which a portfolio security is quoted or denomi-
 nated relative to the U.S. dollar would reduce the value of the portfolio
 security. In addition, if the currency in which an Underlying Fund receives
 dividends, interest or other payments declines in value against the U.S.
 dollar before such income is distributed as dividends to shareholders or
 converted to U.S. dollars, the Underlying Fund may have to sell portfolio
 securities to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the Economic and Monetary Union presents unique uncer-
 tainties, including the legal treatment of certain outstanding financial
 contracts after January 1, 1999 that refer to existing currencies rather
 than the euro; the establishment and maintenance of exchange rates for cur-
 rencies being converted into the euro; the fluctuation of the euro relative
 to non-euro currencies during the transition period from January 1, 1999 to
 December 31, 2001 and beyond; whether the interest rate, tax and labor
 regimes of European countries participating in the euro will converge over
 time; and whether the conversion of the currencies of other coun-
 
50

                                                                      APPENDIX A
 
 tries that may in the future become members of the European Union may have
 an impact on the euro. These or other factors, including political and eco-
 nomic risks, could cause market disruptions, and could adversely affect the
 value of securities held by the Underlying Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Efforts in foreign countries to remediate potential Year 2000 prob-
 lems are not as extensive as those in the United States. As a result, the
 operations of foreign markets, foreign issuers and foreign governments may
 be disrupted by the Year 2000 Problem, and the investment portfolio of an
 Underlying Fund may be adversely affected. Furthermore, with respect to cer-
 tain foreign countries, there is a possibility of nationalization, expropri-
 ation or confiscatory taxation, imposition of withholding or other taxes on
 dividend or interest payments (or, in some cases, capital gains), limita-
 tions on the removal of funds or other assets of the Underlying Funds, and
 political or social instability or diplomatic developments which could
 affect investments in those countries.
 
 Concentration of an Underlying Fund's assets in one or a few countries and
 currencies will subject a Fund to greater risks than if an Underlying Fund's
 assets were not geographically concentrated.
 
 Investment in sovereign debt obligations by certain Underlying Funds
 involves risks not present in debt obligations of corporate issuers. The
 issuer of the debt or the governmental authorities that control the repay-
 ment of the debt may be unable or unwilling to repay principal or pay inter-
 est when due in accordance with the terms of such debt, and an Underlying
 Fund may have limited recourse to compel payment in the event of a default.
 Periods of economic uncertainty may result in volatility of market prices of
 sovereign debt, and in turn an Underlying Fund's NAV, to a greater extent
 than the volatility inherent in debt obligations of U.S. issuers.

 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Underlying Funds may also invest in European
 Depository Receipts ("EDRs") or other similar instruments representing secu-
 rities of foreign issuers. ADRs represent the right to receive securities of
 foreign issuers deposited in a domestic bank or a correspondent bank. Prices
 of ADRs are quoted in U.S. dollars, and ADRs are traded in the United
 States. EDRs and GDRs are receipts
 evidencing an arrangement with a non-U.S. bank. EDRs and GDRs are not neces-
 sarily quoted in the same currency as the underlying security.
 
 Risks of Emerging Countries. Certain Underlying Funds may invest in securi-
 ties of issuers located in emerging countries. The risks of foreign invest-
 ment are heightened when the issuer is located in an emerging country.
 Emerging countries are generally located in the Asia-Pacific region, Eastern
 Europe, Latin and South America and Africa. An Underlying Fund's purchase
 and sale of portfolio securities in certain emerging countries may be con-
 strained by limitations as to daily changes in the prices of listed securi-
 ties, periodic trading or settlement volume and/or limitations on aggregate
 holdings of foreign investors. Such limitations may be computed based on the
 aggregate trading volume by or holdings of an Underlying Fund, the invest-
 ment adviser, its affiliates and their respective clients and other service
 providers. An Underlying Fund may not be able to sell securities in circum-
 stances where price, trading or settlement volume limitations have been
 reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by an Underlying Fund. The repatria-

                                                                      APPENDIX A
 
 tion of both investment income and capital from certain emerging countries
 is subject to restrictions such as the need for governmental consents. Due
 to restrictions on direct investment in equity securities in certain Asian
 countries, it is anticipated that an Underlying Fund may invest in such
 countries through other investment funds in such countries.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant invest-
 ment losses. Investing in emerging countries involves greater risk of loss
 due to expropriation, nationalization, confiscation of assets and property
 or the imposition of restrictions on foreign investments and on repatriation
 of capital invested.
 
 An Underlying Fund's investment in emerging countries may also be subject to
 withholding or other taxes, which may be significant and may reduce the
 return from an investment in such country to the Underlying Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve an Under-
 lying Fund's delivery of securities before receipt of payment for their
 sale. In addition, significant delays are common in certain markets in reg-
 istering the transfer of securities. Settlement or registration problems may
 make it more difficult for an Underlying Fund to value its portfolio securi-
 ties and could cause the Underlying Fund to miss attractive investment
 opportunities, to have a portion of its assets uninvested or to incur losses
 due to the failure of a counterparty to pay for securities the Underlying
 Fund has delivered or the Underlying Fund's inability to complete its con-
 tractual obligations. The creditworthiness of the local securities firms
 used by the Underlying Funds in emerging countries may not be as sound as
 the creditworthiness of firms used in more developed countries. As a result,
 the Under-
 
                                                                              53
<PAGE>
 
 
 lying Fund may be subject to a greater risk of loss if a securities firm
 defaults in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make an Underlying Fund's investments in such countries less liq-
 uid and more volatile than investments in countries with more developed
 securities markets (such as the United States, Japan and most Western Euro-
 pean countries). An Underlying Fund's investments in emerging countries are
 subject to the risk that the liquidity of a particular investment, or
 investments generally, in such countries will shrink or disappear suddenly
 and without warning as a result of adverse economic, market or political
 conditions, or adverse investor perceptions, whether or not accurate.
 Because of the lack of sufficient market liquidity, an Underlying Fund
 may incur losses because it will be required to effect sales at a disadvan-
 tageous time and then only at a substantial drop in price. Investments in
 emerging countries may be more difficult to price precisely because of the
 characteristics discussed above and lower trading volumes.
 
 An Underlying Fund's use of foreign currency management techniques in emerg-
 ing countries may be limited. Due to the limited market for these instru-
 ments in emerging countries, the investment adviser does not currently
 anticipate that a significant portion of the Underlying Funds' currency
 exposure in emerging countries, if any, will be covered by such instruments.
 
 Risks of Derivative Investments. An Underlying Fund's transactions, if any,
 in options, futures, options on futures, swaps, interest rate caps, floors
 and collars, structured securities, inverse floating-rate securities,
 stripped mortgage-backed securities and currency transactions involve addi-
 tional risk of loss. Loss can result from a lack of correlation between
 changes in the value of derivative instruments and the portfolio assets (if
 any) being hedged, the potential illiquidity of the markets for derivative
 instruments, or the risks arising from margin requirements and related lev-
 erage factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the investment adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. The Underlying Funds may also invest in derivative
 investments for non-hedging purposes (that is, to seek to increase total
 return). Investing for non-hedging purposes is considered a speculative
 practice and presents even greater risk of loss.
 
 Derivative mortgage-backed securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact the cash flow and the market value of these securi-
 ties. In general, the risk of faster
 
54
<PAGE>
 
                                                                      APPENDIX A
 
 than anticipated prepayments adversely affects IOs, super floaters and pre-
 mium priced mortgage-backed securities. The risk of slower than anticipated
 prepayments generally adversely affects POs, floating-rate securities sub-
 ject to interest rate caps, support tranches and discount priced mortgage-
 backed securities. In addition, particular derivative securities may be
 leveraged such that their exposure (i.e., price sensitivity) to interest
 rate and/or prepayment risk is magnified.
 
 Some floating-rate derivative debt securities can present more complex types
 of derivative and interest rate risks. For example, range floaters are sub-
 ject to the risk that the coupon will be reduced below market rates if a
 designated interest rate floats outside of a specified interest rate band or
 collar. Dual index or yield curve floaters are subject to lower prices in
 the event of an unfavorable change in the spread between two designated
 interest rates.
 
 Risks of Illiquid Securities. The Underlying Funds may invest up to 15% (10%
 in the case of the Financial Square Prime Obligations Fund) of their net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
  .Both domestic and foreign securities that are not readily marketable
  .Certain municipal leases and participation interests
  .Certain stripped mortgage-backed securities
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain over-the-counter options
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that
   the restricted security is eligible for resale pursuant to Rule 144A
   under the Securities Act of 1933 ("144A Securities") and, therefore, is
   liquid.
 
 Investing in 144A Securities may decrease the liquidity of an Underlying
 Fund's portfolio to the extent that qualified institutional buyers become
 for a time uninterested in purchasing these restricted securities. The pur-
 chase price and subsequent valuation of restricted and illiquid securities
 normally reflect a discount, which may be significant, from the market price
 of comparable securities for which a liquid market exists.
 
 Credit Risks. Debt securities purchased by the Underlying Funds may include
 securities (including zero coupon bonds) issued by the U.S. government (and
 its agencies, instrumentalities and sponsored enterprises), foreign govern-
 ments, domestic and foreign corporations, banks and other issuers. Some of
 these fixed-income securities are described in the next section below. Fur-
 ther information is provided in the Additional Statement.
 
 
                                                                              55
<PAGE>
 
 
 Debt securities rated BBB or higher by Standard & Poor's Ratings Group
 ("Standard & Poor's") or Baa or higher by Moody's Investors Services, Inc.
 ("Moody's") are considered "investment grade." Securities rated BBB or Baa
 are considered medium-grade obligations with speculative characteristics,
 and adverse economic conditions or changing circumstances may weaken their
 issuers' capacity to pay interest and repay principal. A security will be
 deemed to have met a rating requirement if it receives the minimum required
 rating from at least one such rating organization even though it has been
 rated below the minimum rating by one or more other rating organizations, or
 if unrated by such rating organizations, is determined by the Investment
 Adviser to be of comparable credit quality. If a security satisfies an
 Underlying Fund's minimum rating criteria at the time of purchase and is
 subsequently downgraded below such rating, the Underlying Fund will not be
 required to dispose of such security. If a downgrade occurs, the Underlying
 Fund's investment adviser will consider what action, including the sale of
 such security, is in the best interest of the Underlying Fund and its share-
 holders.
 
 Certain Underlying Funds may invest in fixed-income securities rated BB or
 Ba or below (or comparable unrated securities) which are commonly referred
 to as "junk bonds." Junk bonds are considered predominantly speculative and
 may be questionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in an Underlying Fund's portfolio is down-
 graded by a rating organization, the market price and liquidity of such
 security may be adversely affected.
 
 Non-Diversification and Geographic Risks. The Global Income Fund is regis-
 tered as a "non-diversified" fund under the Act and is, therefore, more sus-
 ceptible to adverse developments affecting any single issuer. In addition,
 the Global Income Fund, and certain other Underlying Funds, may invest more
 than 25% of their total assets in the securities of corporate and governmen-
 tal issuers located in a particular foreign country or region. Concentration
 of the investments of these or other Underlying Funds in issuers located in
 a particular country or region will subject the Underlying Fund, to a
 greater extent than if investments were less concentrated, to losses arising
 from adverse developments affecting those issuers or countries.
 
 Temporary Investment Risks. The Underlying Funds may invest a substantial
 portion, and in some cases all, of their total assets, in cash equivalents
 for temporary periods. When an Underlying Fund's assets are invested in such
 instruments, the Underlying Fund may not be achieving its investment objec-
 tive.

 C. Investment Securities and Techniques
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the underlying Funds, including
 their associated risks. Further information is provided in the Additional
 Statement, which is available upon request.
 
 U.S. Government Securities and Related Custodial Receipts. Each Underlying
 Fund may invest in U.S. Government Securities and related custodial
 receipts. U.S. Government Securities include U.S. Treasury obligations and
 obligations issued or guaranteed by U.S. government agencies, instrumentali-
 ties or sponsored enterprises. U.S. Government Securities may be supported
 by (a) the full faith and credit of the U.S. Treasury (such as the Govern-
 ment National Mortgage Association ("Ginnie Mae")); (b) the right of the
 issuer to borrow from the U.S. Treasury (such as securities of the Student
 Loan Marketing Association); (c) the discretionary authority of the U.S.
 government to purchase certain obligations of the issuer (such as the Fed-
 eral National Mortgage Association ("Fannie Mae") and Federal Home Loan
 Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issuer.
 U.S. Government Securities also include Treasury receipts, zero coupon bonds
 and other stripped U.S. Government Securities, where the interest and prin-
 cipal components of stripped U.S. Government Securities are traded indepen-
 dently.
 
 Interests in U.S. Government Securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S. govern-
 ment.
 
 Mortgage-Backed Securities. The Underlying Funds (other than CORE U.S. Equi-
 ty, CORE Large Cap Growth, CORE Large Cap Value, CORE Small Cap Equity and
 CORE International Equity Funds (the "CORE Equity Funds")) may invest in
 these securities that represent direct or indirect participations in, or are
 collateralized by and payable from, mortgage loans secured by real property
 ("Mortgage-Backed Securities"). Mortgage-Backed Securities can be backed by
 either fixed rate mortgage loans or adjustable rate mortgage loans, and may
 be issued by either a governmental or non-governmental entity. Privately
 issued Mortgage-Backed Securities are normally structured with one or more
 types of "credit enhancement." However, these Mortgage-Backed Securities
 typically do not have the same credit standing as U.S. government guaranteed
 Mortgage-Backed Securities.
 
                                                                              57
<PAGE>
 
 
 
 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs"), and real estate mortgage
 investment conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an investor with a specified interest in the cash flow from a
 pool of underlying mortgages or of other Mortgage-Backed Securities. CMOs
 are issued in multiple classes. In most cases, payments of principal are
 applied to the CMO classes in the order of their respective stated maturi-
 ties, so that no principal payments will be made on a CMO class until all
 other classes having an earlier stated maturity date are paid in full. A
 REMIC is a CMO that qualifies for special tax treatment and invests in cer-
 tain mortgages principally secured by interests in real property and other
 permitted investments. Mortgage-Backed Securities also include stripped
 Mortgage-Backed Securities ("SMBS"), which are derivative multiple class
 Mortgage-Backed Securities. SMBS are usually structured with two different
 classes: one that receives 100% of the interest payments and the other that
 receives 100% of the principal payments from a pool of mortgage loans. The
 market value of SMBS consisting entirely of principal payments generally is
 unusually volatile in response to changes in interest rates. The yields on
 SMBS that receive all or most of the interest from mortgage loans are gener-
 ally higher than prevailing market yields on other Mortgage-Backed Securi-
 ties because their cash flow patterns are more volatile and there is a
 greater risk that the initial investment will not be fully recouped.
 
 Asset-Backed Securities. The Underlying Funds (other than the CORE Equity
 Funds) may also invest in asset-backed securities. Asset-backed securities
 are securities whose principal and interest payments are collateralized by
 pools of assets such as auto loans, credit card receivables, leases,
 installment contracts and personal property. Asset-backed securities are
 often subject to more rapid repayment than their stated maturity date would
 indicate as a result of the pass-through of prepayments of principal on the
 underlying loans. During periods of declining interest rates, prepayment of
 loans underlying asset-backed securities can be expected to accelerate.
 Accordingly, an Underlying Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. Asset-backed securities present credit risks
 that are not presented by Mortgage-Backed Securities. This is because asset-
 backed securities generally do not have the benefit of a security interest
 in collateral that is comparable in quality to mortgage assets. There is the
 possibility that, in some cases, recoveries on repossessed collateral may
 not be available to support payments on these securities. In the event of a
 default, an Underlying Fund may suffer a loss if it cannot sell collateral
 quickly and receive the amount it is owed.

                                                                      APPENDIX A
 
 
 Municipal Securities. Certain Underlying Funds may invest in securities and
 instruments issued by state and local governmental issuers. Municipal secu-
 rities consist of bonds, notes, commercial paper and other instruments (in-
 cluding participation interests in such securities) issued by or on behalf
 of states, territories and possessions of the United States (including the
 District of Columbia) and their political subdivisions, agencies or instru-
 mentalities. Such securities may pay fixed, variable or floating rates of
 interest. Municipal securities are often issued to obtain funds for various
 public purposes, including the construction of a wide range of public facil-
 ities such as bridges, highways, housing, hospitals, mass transportation,
 schools, streets and water and sewer works. Other public purposes for which
 municipal securities may be issued include refunding outstanding obliga-
 tions, obtaining funds for general operating expenses, and obtaining funds
 to lend to other public institutions and facilities. Municipal securities in
 which the Underlying Funds may invest include private activity bonds, munic-
 ipal leases, certificates of participation, pre-refunded municipal securi-
 ties and auction rate securities.
 
 Corporate and Bank Obligations; Trust Preferred Securities; Convertible
 Securities. Certain Underlying Funds may invest in corporate debt obliga-
 tions, trust preferred securities and convertible securities. Corporate debt
 obligations include bonds, notes, debentures and other obligations of U.S.
 or foreign corporations to pay interest and repay principal, and include
 securities issued by banks and other financial institutions. Banks are sub-
 ject to extensive but different governmental regulations which may limit
 both the amount and types of loans which may be made and interest rates
 which may be charged. In addition, the profitability of the banking industry
 is largely dependent upon the availability and cost of funds for the purpose
 of financing lending operations under prevailing money market conditions.
 General economic conditions as well as exposure to credit losses arising
 from possible financial difficulties of borrowers play an important part in
 the operation of this industry. A trust preferred or capital security is a
 long dated bond (for example, 30 years) with preferred features. The pre-
 ferred features are that payment of interest can be deferred for a specified
 period without initiating a default event. The securities are generally
 senior in claim to standard preferred stock but junior to other bondholders.
 
 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than nonconvertible securities of similar quali-
 ty. Convertible securities in which an Underlying Fund invests are subject
 to the same rating criteria as its other investments in fixed-income securi-
 ties. Convertible securities have both equity and fixed-income risk charac-
 teristics. Like all fixed-income securities, the value of convertible secu-
 rities is susceptible to the risk of market losses attribut-
 
                                                                              59
<PAGE>
 
 
 able to changes in interest rates. Generally, the market value of convert-
 ible securities tends to decline as interest rates increase and, conversely,
 to increase as interest rates decline. However, when the market price of the
 common stock underlying a convertible security exceeds the conversion price
 of the convertible security, the convertible security tends to reflect the
 market price of the underlying common stock. As the market price of the
 underlying common stock declines, the convertible security, like a fixed-
 income security, tends to trade increasingly on a yield basis, and thus may
 not decline in price to the same extent as the underlying common stock.
 
 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Certain Underlying Funds may invest in zero coupon, deferred interest, pay-
 in-kind and capital appreciation bonds. These securities are issued at a
 discount from their face value because interest payments are typically post-
 poned until maturity. Pay-in-kind securities are securities that have inter-
 est payable by the delivery of additional securities.The market prices of
 these securities generally are more volatile than the market prices of
 interest-bearing securities and are likely to respond to a greater degree to
 changes in interest rates than interest-bearing securities having similar
 maturities and credit quality.
 
 Rating Criteria. Except as noted below, the Underlying Equity Funds (other
 than the CORE Equity Funds, which only invest in debt instruments that are
 cash equivalents) may invest in debt securities rated at least investment
 grade at the time of investment. Investment grade debt securities are secu-
 rities rated BBB or higher by Standard & Poor's or Baa or higher by Moody's.
 The Growth and Income, Capital Growth, Small Cap Value, International Equi-
 ty, Japanese Equity, European Equity, International Small Cap, Emerging Mar-
 kets Equity, Asia Growth and Real Estate Securities Funds may invest up to
 10%, 10%, 35%, 35%, 35%, 35%, 35%, 35%, 35% and 20%, respectively, of their
 total assets in debt securities which are rated in the lowest rating catego-
 ries by Standard & Poor's or Moody's (i.e., BB or lower by Standard & Poor's
 or Ba or lower by Moody's), including securities rated D by Moody's or Stan-
 dard & Poor's. The Mid Cap Value Fund may invest up to 10% of its total
 assets in below investment grade debt securities rated B or higher by Stan-
 dard & Poor's or Moody's. Fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) are commonly referred to as "junk bonds,"
 are considered predominately speculative and may be questionable as to prin-
 cipal and interest payments as described above.
 
 Structured Securities and Inverse Floaters. Certain Underlying Funds may
 invest in structured securities. Structured securities are securities whose
 value is determined by reference to changes in the value of specific curren-
 cies, interest rates, commodities, indices or other financial indicators
 (the "Reference") or the relative change in two or more References. The
 interest rate or the principal amount
 
60
<PAGE>
 
                                                                      APPENDIX A
 
 payable upon maturity or redemption may be increased or decreased depending
 upon changes in the applicable Reference. Structured securities may be posi-
 tively or negatively indexed, so that appreciation of the Reference may pro-
 duce an increase or decrease in the interest rate or value of the security
 at maturity. In addition, changes in the interest rates or the value of the
 security at maturity may be a multiple of changes in the value of the Refer-
 ence. Consequently, structured securities may present a greater degree of
 market risk than other types of fixed-income securities, and may be more
 volatile, less liquid and more difficult to price accurately than less com-
 plex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.
 
 Foreign Currency Transactions. Certain Underlying Funds may, to the extent
 consistent with their investment policies, purchase or sell foreign curren-
 cies on a cash basis or through forward contracts. A forward contract
 involves an obligation to purchase or sell a specific currency at a future
 date at a price set at the time of the contract. An Underlying Fund may
 engage in foreign currency transactions for hedging purposes and to seek to
 protect against anticipated changes in future foreign currency exchange
 rates. In addition, certain Underlying Funds may also enter into such trans-
 actions to seek to increase total return, which is considered a speculative
 practice.
 
 Underlying Funds may also engage in cross-hedging by using forward contracts
 in a currency different from that in which the hedged security is denomi-
 nated or quoted if the investment adviser determines that there is a pattern
 of correlation between the two currencies. An Underlying Fund may hold for-
 eign currency received in connection with investments in foreign securities
 when, in the judgment of the investment adviser, it would be beneficial to
 convert such currency into U.S. dollars at a later date (e.g., the Invest-
 ment Adviser anticipates that the foreign currency will appreciate against
 the U.S. dollar).
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, an Underlying Fund's NAV to fluctu-
 ate. Currency exchange rates also can be affected unpredictably by the
 intervention of U.S. or foreign governments or central banks, or the failure
 to intervene, or by currency controls or political developments in the
 United States or abroad.
 
                                                                              61
<PAGE>
 
 
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are not guaranteed by an exchange or clear-
 inghouse, a default on a contract would deprive an Underlying Fund of
 unrealized profits, transaction costs, or the benefits of a currency hedge,
 or could force the Underlying Fund to cover its purchase or sale commit-
 ments, if any, at the current market price.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Underlying Fund may
 write (sell) covered call and put options and purchase put and call options
 on any securities in which it may invest or on any securities index com-
 prised of securities in which it may invest. An Underlying Fund that invests
 in foreign securities may also purchase and sell (write) put and call
 options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of an investment adviser to manage future price fluctua-
 tions and the degree of correlation between the options and securities (or
 currency) markets. If an investment adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in an Underlying Fund's investment portfolio, the Underlying
 Fund may incur losses that it would not otherwise incur. The use of options
 can also increase an Underlying Fund's transaction costs. Options written or
 purchased by the Underlying Funds may be traded on either U.S. or foreign
 exchanges or over-the-counter. Foreign and over-the-counter options will
 present greater possibility of loss because of their greater illiquidity and
 credit risks.
 
 Yield Curve Options. Certain Underlying Funds may enter into options on the
 yield "spread" or differential between two securities. Such transactions are
 referred to as "yield curve" options. In contrast to other types of options,
 a yield curve option is based on the difference between the yields of desig-
 nated securities rather than the prices of the individual securities, and is
 settled through cash pay-

                                                                      APPENDIX A
 
 ments. Accordingly, a yield curve option is profitable to the holder if this
 differential widens (in the case of a call) or narrows (in the case of a
 put), regardless of whether the yields of the underlying securities increase
 or decrease.
 
 The trading of yield curve options is subject to all of the risks associated
 with the trading of other types of options. In addition, however, such
 options present a risk of loss even if the yield of one of the underlying
 securities remains constant, or if the spread moves in a direction or to an
 extent which was not anticipated.
 
 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. Certain Underlying Funds may engage in
 futures transactions on both U.S. and foreign exchanges.
 
 Certain Underlying Funds may purchase and sell futures contracts, and pur-
 chase and write call and put options on futures contracts, in order to seek
 to increase total return or to hedge against changes in interest rates,
 securities prices or to the extent an Underlying Fund invests in foreign
 securities, currency exchange rates, or to otherwise manage their term
 structures, sector selection and durations in accordance with their invest-
 ment objectives and policies. An Underlying Fund may also enter into closing
 purchase and sale transactions with respect to such contracts and options.
 An Underlying Fund will engage in futures and related options transactions
 for bona fide hedging purposes as defined in regulations of the Commodity
 Futures Trading Commission or to seek to increase total return to the extent
 permitted by such regulations. An Underlying Fund may not purchase or sell
 futures contracts or purchase or sell related options to seek to increase
 total return, except for closing purchase or sale transactions, if immedi-
 ately thereafter the sum of the amount of initial margin deposits and premi-
 ums paid on the Underlying Fund's outstanding positions in futures and
 related options entered into for the purpose of seeking to increase total
 return would exceed 5% of the market value of the Underlying Fund's net
 assets.
 
 Futures contracts and related options present the following risks:

 .   While an Underlying Fund may benefit from the use of futures and options
    on futures, unanticipated changes in interest rates, securities prices or
    currency exchange rates may result in a poorer overall performance than if
    the Underlying Fund had not entered into any futures contracts or options
    transactions.
 
                                                                              63
<PAGE>
 
 
 
 .   Because perfect correlation between a futures position and portfolio posi-
    tion that is intended to be protected is impossible to achieve, the
    desired protection may not be obtained and an Underlying Fund may be
    exposed to additional risk of loss.

 .   The loss incurred by an Underlying Fund in entering into futures contracts
    and in writing call options on futures is potentially unlimited and may
    exceed the amount of the premium received.

 .   Futures markets are highly volatile and the use of futures may increase
    the volatility of an Underlying Fund's NAV.

 .   As a result of the low margin deposits normally required in futures trad-
    ing, a relatively small price movement in a futures contract may result in
    substantial losses to an Underlying Fund.

 .   Futures contracts and options on futures may be illiquid, and exchanges
    may limit fluctuations in futures contract prices during a single day.

 .   Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 Preferred Stock, Warrants and Rights. Certain Underlying Funds may invest in
 preferred stock, warrants and rights. Preferred stocks are securities that
 represent an ownership interest providing the holder with claims on the
 issuer's earnings and assets before common stock owners but after bond own-
 ers. Unlike debt securities, the obligations of an issuer of preferred
 stock, including dividend and other payment obligations, may not typically
 be accelerated by the holders of such preferred stock on the occurrence of
 an event of default or other non-compliance by the issuer of the preferred
 stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.
 
 Loan Participations. Certain Underlying Funds may invest in loan participa-
 tions. A loan participation is an interest in a loan to a U.S. or foreign
 company or other borrower which is administered and sold by a financial
 intermediary. Loan participation interests may take the form of a direct or
 co-lending relationship with the corporate borrower, an assignment of an
 interest in the loan by a co-lender or another participant, or a participa-
 tion in the seller's share of the loan. When the Underlying Fund acts as co-
 lender in connection with a participation interest or when it acquires cer-
 tain participation interests, the Underlying Fund will have direct recourse
 against the borrower if the borrower fails to pay scheduled principal and
 interest. In cases where the Underlying Fund lacks direct recourse, it will

                                                                      APPENDIX A
 
 look to the agent bank to enforce appropriate credit remedies against the
 borrower. In these cases, the Underlying Fund may be subject to delays,
 expenses and risks that are greater than those that would have been involved if
 the Underlying Fund had purchased a direct obligation (such as commercial
 paper) of such borrower. Moreover, under the terms of the loan participation,
 the Underlying Fund may be regarded as a creditor of the agent bank (rather
 than of the underlying corporate borrower), so that the Underlying Fund may
 also be subject to the risk that the agent bank may become insolvent.
 
 Real Estate Investment Trusts ("REITs"). The Real Estate Securities Fund
 expects to invest a substantial portion of its total assets in REITs, which
 are pooled investment vehicles that invest primarily in either real estate
 or real estate related loans. In addition, other Underlying Equity Funds may
 invest in REITs from time to time. The value of a REIT is affected by
 changes in the value of the properties owned by the REIT or securing mort-
 gage loans held by the REIT. REITs are dependent upon the ability of the
 REITs' managers, and are subject to heavy cash flow dependency, default by
 borrowers and the qualification of the REITs under applicable regulatory
 requirements for favorable federal income tax treatment. REITs are also sub-
 ject to risks generally associated with investments in real estate including
 possible declines in the value of real estate, general and local economic
 conditions, environmental problems and changes in interest rates. To the
 extent that assets underlying a REIT are concentrated geographically, by
 property type or in certain other respects, these risks may be heightened.
 Each Underlying Fund will indirectly bear its proportionate share of any
 expenses, including management fees, paid by a REIT in which it invests.
 
 Other Investment Companies. An Underlying Fund may invest in securities of
 other investment companies (including SPDRs and WEBs, as described below)
 subject to statutory limitations. These limitations include a prohibition on
 any Underlying Fund acquiring more than 3% of the voting shares of any other
 investment company, and a prohibition on investing more than 5% of an Under-
 lying Fund's total assets in securities of any one investment company or
 more than 10% of its total assets in securities of all investment companies.
 An Underlying Fund will indirectly bear its proportionate share of any man-
 agement fees and other expenses paid by such other investment companies.
 Such other investment companies will have investment objectives, policies
 and restrictions substantially similar to those of the Underlying Fund and
 will be subject to substantially the same risks.
 
 .Standard and Poor's Depository Receipts. The Underlying Equity Funds may,
  consistent with their investment policies, purchase Standard & Poor's
  Depository Receipts ("SPDRs"). SPDRs are securities traded on the American
  Stock Exchange (the "AMEX") that represent ownership in the SPDR Trust, a
  trust which has been established to accumulate and hold a portfolio of com-
  mon
 
                                                                              65
<PAGE>
 
 
  stocks that is intended to track the price performance and dividend yield
  of the S&P 500. SPDR Trust is sponsored by a subsidiary of the AMEX. SPDRs
  may be used for several reasons, including, but not limited to, facilitat-
  ing the handling of cash flows or trading, or reducing transaction costs.
  The price movement of SPDRs may not perfectly parallel the price action of
  the S&P 500.
 
 .World Equity Benchmark Shares. World Equity Benchmark Shares ("WEBS") are
  shares of an investment company that invests substantially all of its
  assets in securities included in the MSCI indices for specified countries.
  WEBS are listed on the AMEX and were initially offered to the public in
  1996. The market prices of WEBS are expected to fluctuate in accordance
  with both changes in the NAVs of their underlying indices and supply and
  demand of WEBS on the AMEX. To date, WEBS have traded at relatively modest
  discounts and premiums to their NAVs. However, WEBS have a limited operat-
  ing history and information is lacking regarding the actual performance and
  trading liquidity of WEBS for extended periods or over complete market
  cycles. In addition, there is no assurance that the requirements of the
  AMEX necessary to maintain the listing of WEBS will continue to be met or
  will remain unchanged. In the event substantial market or other disruptions
  affecting WEBS should occur in the future, the liquidity and value of an
  Underlying Equity Fund's shares could also be substantially and adversely
  affected. If such disruptions were to occur, an Underlying Equity Fund
  could be required to reconsider the use of WEBS as part of its investment
  strategy.
 
 Unseasoned Companies. Certain Underlying Funds may invest in companies (in-
 cluding predecessors) which have operated less than three years, except that
 this limitation does not apply to debt securities which have been rated
 investment grade or better by at least one rating organization. The securi-
 ties of such companies may have limited liquidity, which can result in their
 being priced higher or lower than might otherwise be the case. In addition,
 investments in unseasoned companies are more speculative and entail greater
 risk than do investments in companies with an established operating record.
 
 Non-Investment Grade Fixed-Income Securities. Non-investment grade fixed-
 income securities and unrated securities of comparable credit quality (com-
 monly known as "junk bonds") are considered predominantly speculative by
 traditional investment standards. In some cases, these obligations may be
 highly speculative and have poor prospects for reaching investment grade
 standing. Non-investment grade fixed-income securities are subject to the
 increased risk of an issuer's inability to meet principal and interest obli-
 gations. These securities, also referred to as high yield securities, may be
 subject to greater price volatility due to such factors as specific corpo-
 rate developments, interest rate sensitivity, negative perceptions of the
 junk bond markets generally and less secondary market liquidity.

                                                                      APPENDIX A
 
 
 Non-investment grade fixed-income securities are generally unsecured and are
 often subordinated to the rights of other creditors of the issuers of such
 securities. Investment by an Underlying Fund in defaulted securities poses
 additional risk of loss should nonpayment of principal and interest continue
 in respect of such securities. Even if such securities are held to maturity,
 recovery by an Underlying Fund of its initial investment and any anticipated
 income or appreciation is uncertain.
 
 Equity Swaps. Each Underlying Equity Fund may invest up to 10% of its total
 assets in equity swaps. Equity swaps allow the parties to a swap agreement
 to exchange dividend income or other components of return on an equity
 investment (for example, a group of equity securities or an index) for a
 component of return on another non-equity or equity investment.
 
 An equity swap may be used by an Underlying Fund to invest in a market with-
 out owning or taking physical custody of securities in circumstances in
 which direct investment may be restricted for legal reasons or is otherwise
 impractical. Equity swaps are derivatives and their value can be very vola-
 tile. To the extent that an investment adviser does not accurately analyze
 and predict the potential relative fluctuation of the components swapped
 with another party, an Underlying Fund may suffer a loss. The value of some
 components of an equity swap (such as the dividends on a common stock) may
 also be sensitive to changes in interest rates. Furthermore, an Underlying
 Fund may suffer a loss if the counterparty defaults.
 
 When-Issued Securities and Forward Commitments. Each Underlying Fund may
 purchase when-issued securities and make contracts to purchase or sell secu-
 rities for a fixed price at a future date beyond customary settlement time.
 When-issued securities are securities that have been authorized, but not yet
 issued. When-issued securities are purchased in order to secure what is con-
 sidered to be an advantageous price and yield to the Underlying Fund at the
 time of entering into the transaction. A forward commitment involves the
 entering into a contract to purchase or sell securities for a fixed price at
 a future date beyond the customary settlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although an Underlying Fund
 will generally purchase securities on a when-issued or forward commitment
 basis with the intention of acquiring securities for its portfolio, an
 Underlying Fund may dispose of when-issued securities or forward commitments
 prior to settlement if its investment adviser deems it appropriate.
 
                                                                              67
<PAGE>
 
 
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. The Underlying Funds may enter into repurchase
 agreements with dealers in U.S. Government Securities and member banks of
 the Federal Reserve System which furnish collateral at least equal in value
 or market price to the amount of their repurchase obligation. Some Under-
 lying Funds may also enter into repurchase agreements involving certain for-
 eign government securities.
 
 If the other party or "seller" defaults, an Underlying Fund might suffer a
 loss to the extent that the proceeds from the sale of the underlying securi-
 ties and other collateral held by the Underlying Fund are less than the
 repurchase price and the Underlying Fund's cost associated with delay and
 enforcement of the repurchase agreement. In addition, in the event of bank-
 ruptcy of the seller, an Underlying Fund could suffer additional losses if a
 court determines that the Underlying Fund's interest in the collateral is
 not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, an investment
 adviser will carefully consider the creditworthiness of the seller. Certain
 Underlying Funds, together with other registered investment companies having
 advisory agreements with the investment adviser or any of its affiliates,
 may transfer uninvested cash balances into a single joint account, the daily
 aggregate balance of which will be invested in one or more repurchase agree-
 ments.
 
 Lending of Portfolio Securities. Each Underlying Fund may engage in securi-
 ties lending. Securities lending involves the lending of securities owned by
 an Underlying Fund to financial institutions such as certain broker-dealers.
 The borrowers are required to secure their loans continuously with cash,
 cash equivalents, U.S. Government Securities or letters of credit in an
 amount at least equal to the market value of the securities loaned. Cash
 collateral may be invested in cash equivalents. If an investment adviser
 determines to make securities loans, the value of the securities loaned may
 not exceed 33 1/3% of the value of the total assets of an Underlying Fund
 (including the loan collateral).
 
 An Underlying Fund may lend its securities to increase its income. An Under-
 lying Fund may, however, experience delay in the recovery of its securities
 if the institution with which it has engaged in a portfolio loan transaction
 breaches its agreement with the Underlying Fund.
 
 Short Sales Against-the-Box. Certain Underlying Funds may make short sales
 against-the-box. A short sale against-the-box means that at all times when a
 short position is open the Underlying Fund will own an equal amount of secu-
 rities sold short, or securities convertible into or exchangeable for, with-
 out the payment of any further consideration, an equal amount of the securi-
 ties of the same issuer as the securities sold short.

                                                                      APPENDIX A
 
 
 Mortgage Dollar Rolls. Certain Underlying Funds may enter into "mortgage
 dollar rolls." In mortgage dollar rolls, an Underlying Fund sells securities
 for delivery in the current month and simultaneously contracts with the same
 counterparty to repurchase substantially similar (same type, coupon and
 maturity) but not identical securities on a specified future date. During
 the roll period, the Underlying Fund loses the right to receive principal
 and interest paid on the securities sold. However, the Underlying Fund bene-
 fits to the extent of any difference between (a) the price received for the
 securities sold and (b) the lower forward price for the future purchase
 and/or fee income plus the interest earned on the cash proceeds of the secu-
 rities sold. Unless the benefits of a mortgage dollar roll exceed the
 income, capital appreciation and gain or loss due to mortgage prepayments
 that would have been realized on the securities sold as part of the roll,
 the use of this technique will diminish the Underlying Fund's performance.
 
 Successful use of mortgage dollar rolls depends upon an investment adviser's
 ability to predict correctly interest rates and mortgage prepayments. If the
 investment adviser is incorrect in its prediction, an Underlying Fund may
 experience a loss. For financial reporting and tax purposes, the Funds treat
 mortgage dollar rolls as two separate transactions: one involving the pur-
 chase of a security and a separate transaction involving a sale. The Under-
 lying Funds do not currently intend to enter into mortgage dollar rolls that
 are accounted for as a financing and do not treat them as borrowings.
 
 Borrowings and Reverse Repurchase Agreements. Each Underlying Fund can bor-
 row money from banks, and certain Underlying Funds enter into reverse repur-
 chase agreements with banks and other financial institutions in amounts not
 exceeding one-third of their total assets. Reverse repurchase agreements
 involve the sale of securities held by an Underlying Fund subject to the
 Underlying Fund's agreement to repurchase them at a mutually agreed upon
 date and price (including interest). These transactions may be entered into
 as a temporary measure for emergency purposes or to meet redemption
 requests. Reverse repurchase agreements may also be entered into when the
 investment adviser expects that the interest income to be earned from the
 investment of the transaction proceeds will be greater than the related
 interest expense. Borrowings and reverse repurchase agreements involve
 leveraging. If the securities held by an Underlying Fund decline in value
 while these transactions are outstanding, the NAV of the Underlying Fund's
 outstanding shares will decline in value by proportionately more than the
 decline in value of the securities. In addition, reverse repurchase agree-
 ments involve the risk that any interest income earned by an Underlying Fund
 (from the investment of the proceeds) will be less than the interest expense
 of the transaction, that the market value of the securities sold by an
 Underlying Fund will decline below the
 
                                                                              69
<PAGE>
 
 
 price the Underlying Fund is obligated to pay to repurchase the securities,
 and that the securities may not be returned to the Underlying Fund.
 
 Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Inter-
 est Rate Caps, Floors and Collars. To the extent consistent with their
 investment policies, the Underlying Funds may enter into interest rate
 swaps, mortgage swaps, credit swaps, currency swaps and interest rate caps,
 floors and collars. Interest rate swaps involve the exchange by an Under-
 lying Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest rate swaps in that
 they represent commitments to pay and receive interest. The notional princi-
 pal amount, however, is tied to a reference pool or pools of mortgages.
 Credit swaps involve the receipt of floating or fixed rate payments in
 exchange for assuming potential credit losses of an underlying security.
 Credit swaps give one party to a transaction the right to dispose of or
 acquire an asset (or group of assets), or the right to receive or make a
 payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest rate, to receive payment of interest
 on a notional principal amount from the party selling such interest rate
 cap. The purchase of an interest rate floor entitles the purchaser, to the
 extent that a specified index falls below a predetermined interest rate, to
 receive payments of interest on a notional principal amount from the party
 selling the interest rate floor. An interest rate collar is the combination
 of a cap and a floor that preserves a certain return within a predetermined
 range of interest rates.
 
 An Underlying Fund may enter into swap transactions for hedging purposes or
 to seek to increase total return. The use of interest rate, mortgage, credit
 and currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If an investment adviser is incorrect in its forecasts of market val-
 ue, interest rates and currency exchange rates, the investment performance
 of an Underlying Fund would be less favorable than it would have been if
 these investment techniques were not used.

Financial Highlights
 
 The financial highlights tables are intended to help you understand a Port-
 folio's financial performance for the past five years (or less if the Port-
 folio has been in operation for less than five years). Certain information
 reflects financial results for a single Portfolio share. The total returns
 in the table represent the rate that an investor would have earned or lost
 on an investment in a Portfolio (assuming reinvestment of all dividends and
 distributions). This information has been audited by Arthur Andersen LLP,
 whose report, along with a Portfolio's financial statements, is included in
 the Portfolio's annual report (available upon request without charge). Dur-
 ing the period shown, the Trust did not offer the Goldman Sachs Conservative
 Strategy Portfolio. Accordingly, there are no financial highlights for this
 Portfolio.

General Investment
Management Approach
 
 Goldman Sachs Asset Management, a separate operating division of Goldman,
 Sachs & Co. ("Goldman Sachs"), serves as investment adviser (the "Investment
 Adviser") to five asset allocation portfolios: the Conservative Strategy
 Portfolio, Balanced Strategy Portfolio (formerly, the Income Strategy Port-
 folio), Growth and Income Strategy Portfolio, Growth Strategy Portfolio and
 Aggressive Growth Strategy Portfolio (referred to as the "Portfolios" or the
 "Funds" interchangeably herein). The Portfolios are intended for investors
 who prefer to have their asset allocation decisions made by professional
 money managers. Each Portfolio seeks to achieve its objectives by investing
 in a combination of underlying funds for which Goldman Sachs now or in the
 future acts as investment adviser or principal underwriter (the "Underlying
 Funds"). Some of these Underlying Funds invest primarily in fixed-income or
 money market securities (the "Underlying Fixed-Income Funds") and other
 Underlying Funds invest primarily in equity securities (the "Underlying
 Equity Funds"). An investor may choose to invest in one or more of the Port-
 folios based on individual investment goals, risk tolerance, and financial
 circumstances.
 
 The investment objectives and policies of the Portfolios are similar to the
 investment objectives and policies of other mutual funds that the Investment
 Adviser manages. Although the objectives and policies may be similar, the
 investment results of the Portfolios may be higher or lower than the results
 of such other mutual funds. The Investment Adviser cannot guarantee, and
 makes no representation, that the investment results of similar funds will
 be comparable even though the funds have the same Investment Adviser.
 
 Goldman Sachs' Asset Allocation Investment Philosophy:
 The Investment Adviser's Quantitative Research Group uses disciplined quan-
 titative models to determine the relative attractiveness of the world's
 stock, bond and currency markets. These models use financial and economic
 variables to capture fundamental relationships that the Quantitative
 Research Group believes make sense. While the Investment Adviser's process
 is rigorous and quantitative, it also incorporates clear economic reasoning
 behind each recommendation.
 
 The Asset Allocation Investment Process involves investing a Portfolio's
 assets in other Goldman Sachs Funds within specified equity and fixed-income
 percentage ranges.
 
- --------------------------------------------------------------------------------
 
                                                                               1
<PAGE>
 
 
 Each Portfolio starts with a strategic allocation among the various asset
 classes. The Investment Adviser then tactically deviates from the strategic
 allocations based on forecasts provided by the models. The tactical process
 seeks to add value by overweighting attractive markets and underweighting
 unattractive markets. Greater deviations from the strategic allocation of a
 given Portfolio result in higher risk that the tactical allocation will
 underperform the strategic allocation. However, the Investment Adviser's
 risk control process balances the amount any asset class can be overweighted
 in seeking to achieve higher expected returns against the amount of risk
 imposed by that deviation from the strategic allocation. The Investment
 Adviser employs Goldman Sachs' proprietary Black-Litterman asset allocation
 technique in an effort to optimally balance these two goals.

Portfolio Investment Objectives and Strategies
 
 Goldman Sachs Conservative Strategy Portfolio
 
   PORTFOLIO FACTS
- --------------------------------------------------------------------------------
 
        Objective:  Current income, consistent with the preservation of capi-
                    tal and secondarily the potential for capital appreciation
 
 Investment Focus:  Primarily domestic fixed-income funds (approximately 80%)
                    focusing on short-term investments and money market funds,
                    with the balance in domestic stock funds and a small allo-
                    cation to a global bond fund
 
 Investment Style:  Asset Allocation
 
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income, consistent with the preservation of cap-
 ital and secondarily also considers the potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 80% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds, with a focus on
 short-term investments including money market funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its assets in
 the Global Income Fund, Financial Square Prime Obligations Fund and CORE
 Large Cap Value Fund. It is expected that the Portfolio will invest more

         Objective:   Current income and long-term capital appreciation
 
  Investment Focus:   Domestic fixed-income funds (approximately 60%), with
                      the remaining balance in domestic and international
                      stock funds and a small allocation to a global bond fund
 
  Investment Style:   Asset Allocation
 
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income and long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 60% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its equity
 allocation in the CORE Large Cap Growth, CORE Large Cap Value and CORE
 International Equity Funds and will invest a relatively significant percent-
 age of its assets in the Global Income Fund. It is expected that the Portfo-
 lio will invest more than 25% of its assets in the Short Duration Government
 Fund.

The Investment Adviser will invest in particular Underlying Funds based on var-
ious criteria. Among other things, the Investment Adviser will analyze the
Underlying Funds' respective investment objectives, policies and investment
strategies in order to determine which Underlying Funds, in combination with
other Underlying Funds, are appropriate in light of a Portfolio's investment
objective.
 
Each Portfolio's turnover rate is expected not to exceed 50% annually. A Port-
folio may purchase or sell securities to: (a) accommodate purchases and sales
of its shares; (b) change the percentages of its assets invested in each of the
Underlying Funds in response to economic or market conditions; and (c) maintain
or modify the allocation of its assets among the Underlying Funds within the
percentage ranges described above.

                                                 PRINCIPAL INVESTMENT STRATEGIES
 
 
 While each Portfolio can invest in any or all of the Underlying Funds, it is
 expected that each Portfolio will normally invest in only some of the Under-
 lying Funds at any particular time. Each Portfolio's investment in any of
 the Underlying Funds may, and in some cases is expected to, exceed 25% of
 such Portfolio's total assets.
 
 THE PARTICULAR UNDERLYING FUNDS IN WHICH EACH PORTFOLIO MAY INVEST, THE
 EQUITY/FIXED-INCOME TARGETS AND RANGES AND THE INVESTMENTS IN EACH UNDER-
 LYING FUND MAY BE CHANGED FROM TIME TO TIME WITHOUT SHAREHOLDER APPROVAL.
 
 In addition, each Portfolio's investment objectives and all policies not
 specifically designated as fundamental in this Prospectus or the Statement
 of Additional Information (the "Additional Statement") are non-fundamental
 and may be changed without shareholder approval. If there is a change in a
 Portfolio's investment objective, you should consider whether that Portfolio
 remains an appropriate investment in light of your then current financial
 position and needs.

Principal Risks of the Portfolios
 
Loss of money is a risk of investing in each Portfolio. An investment in a
Portfolio is not a deposit of any bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other governmental agency. While
the Portfolios offer a greater level of diversification than many other types
of mutual funds, a single Portfolio may not provide a complete investment pro-
gram for an investor. The following summarizes important risks that apply to
the Portfolios and may result in a loss of your investment. There can be no
assurance that a Portfolio will achieve its investment objective.
 
 .Investing in the Underlying Funds--The investments of each Portfolio are
 concentrated in the Underlying Funds, and each Portfolio's investment
 performance is directly related to the investment performance of the
 Underlying Funds held by it. The ability of each Portfolio to meet its
 investment objective is directly related to the ability of the Underlying
 Funds to meet their objectives as well as the allocation among those
 Underlying Funds by the Investment Adviser. The value of the Underlying Funds'
 investments, and the net asset values ("NAV") of the shares of both the
 Portfolios and the Underlying Funds, will fluctuate in response to various
 market and economic factors related to the equity and fixed-income markets, as
 well as the financial condition and prospects of issuers in which the
 Underlying Funds invest. There can be no assurance that the investment
 objective of any Portfolio or any Underlying Fund will be achieved.
 .Investments of the Underlying Funds--Because the Portfolios invest in the
 Underlying Funds, the Portfolios' shareholders will be affected by the
 investment policies of the Underlying Funds in direct proportion to the amount
 of assets the Portfolios allocate to those Funds. Each Portfolio may invest in
 Underlying Funds that in turn invest in small capitalization companies and
 foreign issuers and thus are subject to additional risks, including changes in
 foreign currency exchange rates and political risk. Foreign investments may
 include securities of issuers located in emerging countries in Asia, Latin
 America, Eastern Europe and Africa. Each Portfolio may also invest in
 Underlying Funds that in turn invest in non-investment grade fixed-income
 securities ("junk bonds"), which are considered speculative by traditional
 standards. In addition, the Underlying Funds may purchase derivative
 securities; enter into forward currency transactions; lend their portfolio
 securities; enter into futures contracts and options transactions; purchase
 zero coupon bonds and payment-in-kind bonds; purchase securities issued by
 real estate investment trusts ("REITs") and other issuers in the real estate
 industry; purchase restricted and illiquid securities; purchase securities on
 a when-issued or delayed delivery basis; enter into repurchase agreements;
 borrow money; and

 engage in various other investment practices. The risks presented by these
 investment practices are discussed in Appendix A to this Prospectus and the
 Additional Statement.
 .Affiliated Persons--In managing the Portfolios, the Investment Adviser will
 have the authority to select and substitute Underlying Funds. The Investment
 Adviser is subject to conflicts of interest in allocating Portfolio assets
 among the various Underlying Funds both because the fees payable to it and/or
 its affiliates by some Underlying Funds are higher than the fees payable by
 other Underlying Funds and because the Investment Adviser and its affiliates
 are also responsible for managing the Underlying Funds. The Trustees and
 officers of the Goldman Sachs Trust may also have conflicting interests in
 fulfilling their fiduciary duties to both the Portfolios and the Underlying
 Funds.
 .Expenses--You may invest in the Underlying Funds directly. By investing in the
 Underlying Funds indirectly through a Portfolio, you will incur not only a
 proportionate share of the expenses of the Underlying Funds held by the
 Portfolio (including operating costs and investment management fees), but also
 expenses of the Portfolio.
 .Temporary Investments--Although the Portfolios normally seek to remain
 substantially invested in the Underlying Funds, each Portfolio may invest a
 portion of its assets in high-quality, short-term debt obligations (including
 commercial paper, certificates of deposit, bankers' acceptances, repurchase
 agreements, debt obligations backed by the full faith and credit of the U.S.
 government and demand and time deposits of domestic and foreign banks and
 savings and loan associations) to maintain liquidity, to meet shareholder
 redemptions and for other short-term cash needs. Also, there may be times
 when, in the opinion of the Investment Adviser, abnormal market or economic
 conditions warrant that, for temporary defensive purposes, a Portfolio may
 invest without limitation in short-term obligations. When a Portfolio's assets
 are invested in such investments, the Portfolio may not be achieving its
 investment objective.
 .Other Risks--Each Portfolio is subject to other risks, such as (1) the risk
 that the operations of a Portfolio and the Underlying Funds in which it
 invests, or the value of their securities, will be disrupted by the "Year 2000
 Problem;" (2) the risk that a Portfolio will not be able to pay redemption
 proceeds within the period stated in this Prospectus because of unusual market
 conditions, an unusually high volume of redemption requests or other reasons
 (Liquidity Risk); or (3) the risk that a strategy used by the Investment
 Adviser may fail to produce the intended results (Management Risk).

 DESCRIPTION OF THE UNDERLYING FUNDS
 
 The following is a concise description of the investment objectives and
 practices for each of the Underlying Funds that are available for investment
 by the Portfolios as of the date of this Prospectus. A Portfolio may also
 invest in other Underlying Funds not listed below that may become available
 for investment in the future at the discretion of the Investment Adviser
 without shareholder approval. Additional information regarding the invest-
 ment practices of the Underlying Funds is provided in Appendix A to this
 Prospectus and the Additional Statement. No offer is made in this Prospectus
 of any of the Underlying Funds.

Principal Risks of the Underlying Funds
 
The following summarizes important risks that apply to the Underlying Funds and
may result in a loss of your investment in a Portfolio. There can be no assur-
ance that an Underlying Fund will achieve its investment objective.
 
Risks That Apply To All Underlying Funds:
 
 .Interest Rate Risk--The risk that when interest rates increase, fixed-income
 securities held by an Underlying Fund will decline in value. Long-term fixed-
 income securities will normally have more price volatility because of this
 risk than short-term securities.
 .Credit/Default Risk--The risk that an issuer of fixed-income securities held
 by an Underlying Fund (which may have low credit ratings) may default on its
 obligation to pay interest and repay principal.
 .Market Risk--The risk that the value of the securities in which an Underlying
 Fund invests may go up or down in response to the prospects of individual com-
 panies and/or general economic conditions. Price changes may be temporary or
 last for extended periods.
 .Derivatives Risk--The risk that loss may result from an Underlying Fund's
 investments in options, futures, swaps, structured securities and other deriv-
 ative instruments. These instruments may be leveraged so that small changes
 may produce disproportionate losses to an Underlying Fund.
 .Foreign Risk--The risk that when an Underlying Fund invests in foreign securi-
 ties, it will be subject to the risks of loss not typically associated with
 domestic issuers. Loss may result because of less foreign government regula-
 tion, less public information and less economic, political and social stabili-
 ty. Loss may also result from the imposition of exchange controls, confisca-
 tions and other government restrictions. The Underlying Funds will also be
 subject to the risk of negative foreign currency rate fluctuations. Foreign
 risks will normally be greatest when an Underlying Fund invests in issuers
 located in emerging countries.
 .Management Risk--The risk that a strategy used by an investment adviser to the
 Underlying Funds may fail to produce the intended results.
 .Liquidity Risk--The risk that an Underlying Fund will not be able to pay
 redemption proceeds within the time period stated in this Prospectus, because
 of unusual market conditions, an unusually high volume of redemption requests,
 or other reasons. Underlying Funds that invest in non-investment grade fixed-
 income securities, small capitalization stocks, REITs or emerging country
 issuers will be especially subject to the risk that during certain periods the
 liquidity of particular issuers or industries, or all securities within these
 investment categories, will

 shrink or disappear suddenly and without warning as a result of adverse eco-
 nomic, market or political events, or adverse investor perceptions whether or
 not accurate.
 .Other Risks--Each Underlying Fund is subject to other risks, such as the risk
 that its operations, or the value of its portfolio securities, will be dis-
 rupted by the "Year 2000 Problem."
 
Risks That Apply Primarily To The Underlying Fixed-Income Funds:
 
 .Call Risk--The risk that an issuer will exercise its right to pay principal on
 an obligation held by an Underlying Fund (such as a Mortgage-Backed Security)
 earlier than expected. This may happen when there is a decline in interest
 rates. Under these circumstances, an Underlying Fund may be unable to recoup
 all of its initial investment and will also suffer from having to reinvest in
 lower yielding securities.
 .Extension Risk--The risk that an issuer will exercise its right to pay princi-
 pal on an obligation held by an Underlying Fund (such as a Mortgage-Backed
 Security) later than expected. This may happen when there is a rise in inter-
 est rates. Under these circumstances, the value of an obligation will
 decrease, and an Underlying Fund will also suffer from the inability to invest
 in higher yielding securities.
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risk That Applies Primarily To The Underlying Equity Funds:
 
 .Stock Risk--The risk that stock prices have historically risen and fallen in
 periodic cycles. As of the date of this Prospectus, U.S. stock markets and
 certain foreign stock markets were trading at or close to record high levels.
 There is no guarantee that such levels will continue.
 
Risks That Are Particularly Important For Specific Underlying Funds:
 
 .Country Risk--The European Equity Fund invests primarily in equity securities
 of European companies. The Japanese Equity Fund invests primarily in equity
 securities of Japanese companies. The Asia Growth Fund invests primarily in
 equity securities of Asian issuers. The Global Income Fund is non-diversified.
 The Global Income Fund may invest more than 25% of its total assets in the
 securities of corporate and governmental issuers located in each of Canada,
 Germany, Japan, and the United Kingdom as well as in the securities of U.S.
 issuers. Concentration of the investments of these or other Underlying Funds
 in issuers located in a particular country or region will subject the Under-
 lying Fund, to a greater extent than if investments were less concentrated, to
 losses arising from adverse developments affecting those issuers or countries.
 
                                                                              19
<PAGE>
 
 
 .Emerging Countries Risk--Certain Underlying Funds invest in emerging country
 securities. The securities markets of Asian, Latin American, Eastern European,
 African and other emerging countries are less liquid, are especially subject
 to greater price volatility, have smaller market capitalizations, have less
 government regulation and are not subject to as extensive and frequent
 accounting, financial and other reporting requirements as the securities mar-
 kets of more developed countries. Further, investment in equity securities of
 issuers located in Russia and certain other emerging countries involves risk
 of loss resulting from problems in share registration and custody and substan-
 tial economic and political disruptions. These risks are not normally associ-
 ated with investments in more developed countries.
 .Small Cap Stock and REIT Risks--Certain Underlying Funds invest in small cap
 stocks and REITs. The securities of small capitalization companies and REITs
 involve greater risks than those associated with larger, more established com-
 panies and may be subject to more abrupt or erratic price movements. Securi-
 ties of such issuers may lack sufficient market liquidity to enable an Under-
 lying Fund to effect sales at an advantageous time or without a substantial
 drop in price.
 ."Junk Bond" Risk--Certain Underlying Funds invest in non-investment grade
 fixed-income securities (commonly known as "junk bonds") that are considered
 predominantly speculative by traditional investment standards. Non-investment
 grade fixed-income securities and unrated securities of comparable credit
 quality are subject to the increased risk of an issuer's inability to meet
 principal and interest obligations. These securities may be subject to greater
 price volatility due to such factors as specific corporate developments,
 interest rate sensitivity, negative perceptions of the junk bond markets gen-
 erally and less secondary market liquidity.
 
More information about the portfolio securities and investment techniques of
the Underlying Funds, and their associated risks, is provided in Appendix A.
You should consider the investment risks discussed in this section and in
Appendix A. Both are important to your investment choice.

 ing in a Portfolio by showing: (a) changes in the performance of a Portfo-
 lio's Service Shares from year to year; and (b) how the average annual
 returns of a Portfolio's Service Shares compare to those of broad-based
 securities market indices. The bar chart and table assume reinvestment of
 dividends and distributions. A Portfolio's past performance is not necessar-
 ily an indication of how the Portfolio will perform in the future. Perfor-
 mance reflects expense limitations in effect. If expense limitations were
 not in place, a Portfolio's performance would have been reduced. The Conser-
 vative Strategy Portfolio did not commence operations until February 8,
 1999. Since the Portfolio has less than one calendar year's performance, no
 performance information is provided in this section.

Portfolio Fees and Expenses continued
 
/1/The Portfolios' annual operating expenses have been restated to reflect cur-
rent fees, except for the Conservative Strategy Portfolio, whose expenses are
estimated for the current fiscal year. "Underlying Fund Expenses" for each
Portfolio are based upon the strategic allocation of each Portfolio's invest-
ment in the Underlying Funds and upon the actual total operating expenses of
the Underlying Funds (including any current waivers and expense limitations of
the Underlying Funds). Actual Underlying Fund Expenses incurred by each Portfo-
lio may vary with changes in the allocation of each Portfolio's assets among
the Underlying Funds and with other events that directly affect the expenses of
the Underlying Funds.
/2/The Investment Adviser has voluntarily agreed not to impose a portion of the
management fee on the Portfolios equal to 0.20% of the Portfolios' average
daily net assets. As a result of fee waivers, current management fees of the
Portfolios are 0.15% of each Portfolio's average daily net assets. The waivers
may be terminated at any time at the option of the Investment Adviser.
/3/Service Organizations may charge other fees to their customers who are bene-
ficial owners of Service Shares in connection with their customers' accounts.
Such fees may affect the return customers realize with respect to their invest-
ments.
/4/"Other Expenses" include transfer agency fees equal to 0.04% of the average
daily net assets of each Portfolio's Service Shares plus all other ordinary
expenses not detailed above. The Investment Adviser has voluntarily agreed to
reduce or limit "Other Expenses" (excluding management fees, transfer agency
fees, service fees, taxes, interest and brokerage fees and litigation, indemni-
fication and other extraordinary expenses) to 0.00% of each Portfolio's average
daily net assets.

Example
 
The following Example is intended to help you compare the cost of investing in
a Portfolio (without the waivers and expense limitations) with the cost of
investing in other mutual funds. The Example assumes that you invest $10,000 in
Service Shares of a Portfolio for the time periods indicated and then redeem
all of your shares at the end of those periods. The Example also assumes that
your investment has a 5% return each year and that a Portfolio's operating
expenses remain the same. Although your actual costs may be higher or lower,
based on these assumptions your costs would be:

Service Organizations that invest in Service Shares on behalf of their custom-
ers may charge other fees directly to their customers' accounts in connection
with their investments. You should contact your Service Organization for infor-
mation regarding such charges. Such fees, if any, may affect the return such
customers realize with respect to their investments.
 
Certain Service Organizations may receive other compensation in connection with
the sale and distribution of Service Shares or for services to their customers'
accounts and/or the Portfolios. For additional information regarding such com-
pensation, see "Shareholder Guide" in the Prospectus and "Other Information" in

 The difference, if any, between the stated fees and the actual fees paid by
 the Portfolios reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
                                                                              31

In addition, each Portfolio, as a shareholder in the Underlying Funds, will
indirectly bear a proportionate share of any investment management fees and
other expenses paid by the Underlying Funds. The following chart shows the cur-
rent total net operating expense ratios (management fee plus other operating
expenses) of Institutional Shares of each Underlying Fund in which the Portfo-
lios may invest after applicable fee waivers and expense limitations. In addi-
tion, the following chart shows the contractual investment management fees pay-
able to the investment adviser and its affiliates by the Underlying Funds (in
each case as an annualized percentage of a Fund's average net assets). Absent
voluntary fee waivers and/or expense reimbursements, which may be discontinued
at any time, the total operating expense ratios of certain Underlying Funds
would be higher.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Portfolio's shares.
 Goldman Sachs, 4900 Sears Tower, Chicago, Illinois, 60606-6372, also serves
 as each Portfolio's transfer agent (the "Transfer Agent") and, as such, per-
 forms various shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Underlying Funds or Portfolios. Goldman Sachs reserves
 the right to redeem at any time some or all of the shares acquired for its
 own amount.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to an Underlying Fund or limit an Underlying Fund's investment activities.
 Goldman Sachs and its affiliates engage in proprietary trading and advise
 accounts and funds which have investment objectives similar to those of the
 Underlying Funds and/or which engage in and compete for transactions in the
 same types of securities, currencies and instruments as the Underlying
 Funds. Goldman Sachs and its affiliates will not have any obligation to make
 available any information regarding their proprie-

 tary activities or strategies, or the activities or strategies used for
 other accounts managed by them, for the benefit of the management of the
 Underlying Funds. The results of an Underlying Fund's investment activities,
 therefore, may differ from those of Goldman Sachs and its affiliates, and it
 is possible that an Underlying Fund could sustain losses during periods in
 which Goldman Sachs and its affiliates and other accounts achieve signifi-
 cant profits on their trading for proprietary or other accounts. In addi-
 tion, the Underlying Funds may, from time to time, enter into transactions
 in which other clients of Goldman Sachs have an adverse interest. An Under-
 lying Fund's activities may be limited because of regulatory restrictions
 applicable to Goldman Sachs and its affiliates, and/or their internal poli-
 cies designed to comply with such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Portfolios and the Underlying Funds could be
 adversely affected in their ability to process securities trades, price
 securities, provide shareholder account services and otherwise conduct nor-
 mal business operations if the Investment Adviser or other service providers
 do not adequately address this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Portfolios' other
  service providers that they are taking the steps necessary so that they do
  not experience Year 2000 Problems, and the Investment Adviser will continue
  to monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Portfolios at current levels.
 
                                                                              35
<PAGE>
 
 
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Portfolios. The Investment
 Adviser may obtain such Year 2000 information from various sources which the
 Investment Adviser believes to be reliable, including the issuers' public
 regulatory filings. However, the Investment Adviser is not in a position to
 verify the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Portfolios' other service providers will be
 sufficient to avoid any adverse effect on the Portfolios due to the Year
 2000 Problem.

Dividends
 
Each Fund pays dividends from its net investment income and distributions from
net realized capital gains. You may choose to have dividends and distributions
paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 .Shares of the same or an equivalent class of another Goldman Sachs Fund. Spe-
 cial restrictions may apply for certain ILA Portfolios. See the Additional
 Statement.
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time before the record date for a
particular dividend or distribution. If you do not indicate any choice, your
dividends and distributions will be reinvested automatically in the applicable
Fund.
 
The election to reinvest dividends and distributions in additional shares will
not affect the tax treatment of such dividends and distributions, which will be
treated as received by you and then used to purchase the shares.
 
Dividends from net investment income and distributions from net capital gains
are declared and paid as follows:

From time to time a portion of a Portfolio's dividends may constitute a return
of capital.
 
At the time of an investor's purchase of shares of a Portfolio, a portion of
the NAV per share may be represented by undistributed income or realized or
unrealized appreciation of the Portfolio's portfolio securities. Therefore,
subsequent distributions on such shares from such income or realized apprecia-
tion may be taxable to the investor even if the NAV of the shares is, as a
result of the distributions, reduced below the cost of such shares and the dis-
tributions (or portions thereof) represent a return of a portion of the pur-
chase price.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Service
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Service Shares Of The Funds?
 Generally, Service Shares may be purchased only through institutions that
 have agreed to provide account administration and personal and account main-
 tenance services to their customers who are the beneficial owners of Service
 Shares. These institutions are called "Service Organizations." Customers of
 a Service Organization will normally give their purchase instructions to the
 Service Organization, and the Service Organization will, in turn, place pur-
 chase orders with Goldman Sachs. Service Organizations will set times by
 which purchase orders and payments must be received by them from their cus-
 tomers. Generally, Service Shares may be purchased from the Funds on any
 business day at their net asset value ("NAV") next determined after receipt
 of an order by Goldman Sachs from a Service Organization. No sales load is
 charged. Purchases of Service Shares must be settled within three business
 days of receipt of a complete purchase order.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place an order with Goldman Sachs at 1-800-621-2550 and either:
 .Wire federal funds to The Northern Trust Company ("Northern"), as
  subcustodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian) on the next business day; or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Northern;
  or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Service Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers

                                                               SHAREHOLDER GUIDE
 
 .Responding to inquiries from prospective and existing shareholders
 .Assisting customers with investment procedures
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of Goldman Sachs Trust (the "Trust"), purchase, redemption
 and exchange orders placed by or on behalf of their customers, and may des-
 ignate other intermediaries to accept such orders, if approved by the Trust.
 In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to a service plan adopted by the Trust's Board of Trustees, Service
 Organizations are entitled to receive payment for their services from the
 Trust of up to 0.50% (on an annualized basis) of the average daily net
 assets of the Service Shares of the Funds, which are attributable to or held
 in the name of the Service Organization for its customers.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 In addition to Service Shares, each Fund also offers other classes of shares
 to investors. These other share classes are subject to different fees and
 expenses (which affect performance), have different minimum investment
 requirements and
 are entitled to different services than Service Shares. Information regard-
 ing these other share classes may be obtained from your sales representative
 or from Goldman Sachs by calling the number on the back cover of this Pro-
 spectus.
 
                                                                              39
<PAGE>
 
 
 What Is My Minimum Investment In The Funds?
 The Funds do not have any minimum purchase or account requirements with
 respect to Service Shares. A Service Organization may, however, impose a
 minimum amount for initial and subsequent investments in Service Shares, and
 may establish other requirements such as a minimum account balance. A Serv-
 ice Organization may redeem Service Shares held by non-complying accounts,
 and may impose a charge for any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Reject or restrict any purchase or exchange orders by a particular pur-
  chaser (or group of related purchasers). This may occur, for example, when
  a pattern of frequent purchases, sales or exchanges of Service Shares of a
  Fund is evident, or if purchases, sales or exchanges are, or a subsequent
  abrupt redemption might be, of a size that would disrupt the management of
  a Fund.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Service Shares
 is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                (Value of Assets of the Class)
                 - (Liabilities of the Class)
     NAV =
                -------------------------------
                 Number of Outstanding Shares
                         of the Class
 
 The Funds' investments are valued based on market quotations or, if accurate
 quotations are not readily available, the fair value of the Fund's invest-
 ments may be determined in good faith under procedures established by the
 Trustees.
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will not be priced on any day
  the New York Stock Exchange is closed.
 .When you buy shares, you pay the NAV next calculated after the Funds
  receive your order in proper form.
 .When you sell shares, you receive the NAV next calculated after the Funds
  receive your order in proper form.
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if

 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 In addition, the impact of events that occur after the publication of market
 quotations used by a Fund to price its securities but before the close of
 regular trading on the New York Stock Exchange will normally not be
 reflected in a Fund's next determined NAV unless the Trust, in its discre-
 tion, makes an adjustment in light of the nature and materiality of the
 event, its effect on Fund operations and other relevant factors.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Service Shares Of The Funds?
 Generally, Service Shares may be sold (redeemed) only through Service Orga-
 nizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. Generally,
 each Fund will redeem its Service Shares upon request on any business day at
 their NAV next determined after receipt of such request in proper form.
 Redemption proceeds may be sent to recordholders by check or by wire (if the
 wire instructions are on record).
 
 A Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is elected on the Account
 Application.

 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not
 
                                                                              41
<PAGE>
 
 employed, the Trust may be liable for any loss due to unauthorized or fraud-
 ulent transactions. The following general policies are currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: The Funds will arrange for redemption proceeds to be wired as fed-
 eral funds to the bank account designated in the recordholder's Account
 Application. The following general policies govern wiring redemption pro-
 ceeds:
 .Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request. If the shares to be sold were recently paid for by
  check, the Fund will pay the redemption proceeds when the check has
  cleared, which may take up to 15 days. If the Federal Reserve Bank is
  closed on the day that the redemption proceeds would ordinarily be wired,
  wiring the redemption proceeds may be delayed one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  Account Application to the Service Organization.
 .Neither the Trust, nor Goldman Sachs assume any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organization.
 
 By Check: A recordholder may elect in writing to receive redemption proceeds
 by check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of receipt of a properly exe-
 cuted redemption request. If the shares to be sold were recently paid for by
 check, the Fund will pay the redemption proceeds when the check has cleared,
 which may take up to 15 days.

 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem the Service Shares of any Service Organization whose account balance
  falls below $50 as a result of a redemption. The Funds will not redeem
  Service Shares on this basis if the value of the account falls below the
  minimum account balance solely as a result of market conditions. The Fund
  will give 60 days' prior written notice to allow a Service Organization to
  purchase sufficient additional shares of the Fund in order to avoid such
  redemption.
 .Redeem the shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Service Shares of a Fund at NAV for
 Service Shares of any other Goldman Sachs Fund. The exchange privilege may
 be materially modified or withdrawn at any time upon 60 days' written notice
 to you.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirement of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will Be Sent Regarding Investments In Service Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Service Organizations
 will also be provided with a printed confirmation for each transaction in
 their account and a monthly account statement. Service Organizations are
 responsible for providing these or other reports to their customers who are
 the beneficial owners of Service Shares in accordance with the rules that
 apply to their accounts with the Service Organizations.

Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Portfolio distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Portfolio's net investment income, certain net real-
 ized foreign exchange gains and net short-term capital gains. They are tax-
 able as long-term capital gains to the extent they are attributable to the
 Portfolio's excess of net long-term capital gains (including long-term capi-
 tal gain distributions received from Underlying Fund investments) over net
 short-term capital losses. The tax status of any distribution is the same
 regardless of how long you have been in the Portfolio and whether you rein-
 vest in additional shares or take the distribution as cash. Certain distri-
 butions paid by a Portfolio in January of a given year may be taxable to
 shareholders as if received the prior December 31. The tax status and
 amounts of the distributions for each calendar year will be detailed in your
 annual tax statement from the Portfolio.
 
 The REIT investments of the underlying Real Estate Securities Fund often do
 not provide complete tax information to the Fund until after the calendar
 year-end. Consequently, because of the delay, it may be necessary for the
 Asset Allocation Portfolios to request permission to extend the deadline for
 issuance of Forms 1099-DIV beyond January 31.
 
 A Portfolio's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Portfolio receives from Underlying
 Fund investments may be eligible, in the hands of the corporate sharehold-
 ers, for the corporate dividends-received deduction, subject to certain
 holding period requirements and debt financing limitations.
 
 There are certain tax requirements that all Portfolios must follow in order
 to avoid federal taxation. In its efforts to adhere to these requirements,
 the Portfolios may have to limit their investment activity in some types of
 instruments.
 
 TAXABILITY OF SALES AND EXCHANGES
 
 
 Any sale or exchange of Portfolio shares may generate a tax liability (un-
 less your investment is in an IRA or other tax-advantaged account). Depend-
 ing upon the purchase or sale price of the shares you sell or exchange, you
 may have a gain or a loss on the transaction.
 
 You will recognize taxable gain or loss on a sale, exchange or redemption of
 your shares, including an exchange for shares of another Portfolio, based on
 the differ-
 
                                                                              45
<PAGE>
 
 
 ence between your tax basis in the shares and the amount you receive for
 them. (To aid in computing your tax basis, you generally should retain your
 account statements for the periods that you hold shares.) Any loss recog-
 nized on shares held for six months or less will be treated as a long-term
 capital loss to the extent of any capital gain dividends that were received
 with respect to the shares.
 
 In addition to federal income taxes, you may be subject to state, local or
 foreign taxes on payments received from a Portfolio or on the value of the
 shares held by you. More tax information is provided in the Additional
 Statement. You should also consult your own tax adviser for information
 regarding all tax consequences applicable to your investments in the Portfo-
 lios.

Appendix A
Additional Information on the Underlying Funds
 
 This Appendix provides further information on certain types of securities
 and techniques that may be used by the Underlying Funds, including their
 associated risks. Additional information is provided in the Additional
 Statement, which is available upon request, and in the prospectuses of the
 Underlying Funds.
 
 The Underlying Equity Funds invest primarily in common stocks and other
 equity securities, including preferred stocks, interests in real estate
 investment trusts, convertible debt obligations, convertible preferred
 stocks, equity interests in trusts, partnerships, joint ventures, limited
 liability companies and similar enterprises, warrants and stock purchase
 rights ("equity securities"). The Underlying Fixed-Income Funds invest pri-
 marily in fixed-income securities, including senior and subordinated corpo-
 rate debt obligations (such as bonds, debentures, notes and commercial
 paper), convertible and non-convertible corporate debt obligations, loan
 participations and preferred stock.
 
 The Short-Duration Government and Adjustable Rate Government Funds invest in
 U.S. Government Securities and related repurchase agreements, and neither of
 these Underlying Funds, the Government Income Fund nor the Financial Square
 Prime Obligations Fund makes foreign investments. The investments of the
 Financial Square Prime Obligations Fund are limited by SEC regulations
 applicable to money market funds as described in its prospectus, and do not
 include many of the types of investments discussed below that are permitted
 for the other Underlying Funds. With these exceptions, and the further
 exceptions noted below, the following description applies generally to the
 Underlying Funds.
 
 A. General Risks of the Underlying Funds
 
 The Underlying Equity Funds will be subject to the risks associated with
 common stocks and other equity securities. In general, stock values fluctu-
 ate in response to the activities of individual companies and in response to
 general market and economic conditions. Accordingly, the value of the stocks
 that an Underlying Fund holds may decline over short or extended periods.
 The stock markets tend to be cyclical, with periods when stock prices gener-
 ally rise and periods when prices generally decline.
 
 The Underlying Fixed-Income Funds will be subject to the risks associated
 with fixed-income securities. These risks include interest rate risk, credit
 risk and call/extension risk. In general, interest rate risk involves the
 risk that when interest
 
                                                                              47
<PAGE>
 
 
 rates decline, the market value of fixed-income securities tends to
 increase. Conversely, when interest rates increase, the market value of
 fixed-income securities tends to decline. Credit risk involves the risk that
 an issuer could default on its obligations, and an Underlying Fund will not
 recover its investment. Call risk and extension risk are normally present in
 adjustable rate mortgage loans ("ARMs"), mortgage-backed securities and
 asset-backed securities. For example, homeowners have the option to prepay
 their mortgages. Therefore, the duration of a security backed by home mort-
 gages can either shorten (call risk) or lengthen (extension risk). In gener-
 al, if interest rates on new mortgage loans fall sufficiently below the
 interest rates on existing outstanding mortgage loans, the rate of prepay-
 ment would be expected to increase. Conversely, if mortgage loan interest
 rates rise above the interest rates on existing outstanding mortgage loans,
 the rate of prepayment would be expected to decrease. In either case, a
 change in the prepayment rate can result in losses to investors.
 
 The Financial Square Prime Obligations Fund attempts to maintain a stable
 NAV of $1.00 per share and values its assets using the amortized cost method
 in accordance with SEC regulations. There is no assurance, however, that the
 Financial Square Prime Obligations Fund will be successful in maintaining
 its per share value at $1.00 on a continuous basis. The per share NAVs of
 the other Underlying Funds are expected to fluctuate on a daily basis.
 
 The portfolio turnover rates of the Underlying Funds have ranged from 30% to
 315% during their most recent fiscal years. A high rate of portfolio turn-
 over (100% or more) involves correspondingly greater expenses which must be
 borne by an Underlying Fund and its shareholders. The portfolio turnover
 rate is calculated by dividing the lesser of the dollar amount of sales or
 purchases of portfolio securities by the average monthly value of an Under-
 lying Fund's portfolio securities, excluding securities having a maturity at
 the date of purchase of one year or less. There can be no assurance that the
 turnover rates of the Underlying Funds will remain within this range during
 subsequent fiscal years. Higher turnover rates may result in higher broker-
 age costs and expenses for the Underlying Funds. In addition, higher turn-
 over rates may result in higher taxable realized gains for shareholders.
 
 B. Other Risks of the Underlying Funds
 
 Risks of Investing in Small Capitalization Companies and REITs. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such

<PAGE>
 
                                                                      APPENDIX A
 
 securities. Small capitalization companies and REITs may be thinly traded
 and may have to be sold at a discount from current market prices or in small
 lots over an extended period of time. In addition, these securities are sub-
 ject to the risk that during certain periods the liquidity of particular
 issuers or industries, or all securities in these investment categories,
 will shrink or disappear suddenly and without warning as a result of adverse
 economic or market conditions, or adverse investor perceptions, whether or
 not accurate. Because of the lack of sufficient market liquidity, an Under-
 lying Fund may incur losses because it will be required to effect sales at a
 disadvantageous time and only then at a substantial drop in price. Small
 capitalization companies and REITs include "unseasoned" issuers that do not
 have an established financial history; often have limited product lines,
 markets or financial resources; may depend on or use a few key personnel for
 management; and may be susceptible to losses and risks of bankruptcy. Trans-
 action costs for these investments are often higher than those for larger
 capitalization companies. Investments in small capitalization companies and
 REITs may be more difficult to price precisely than other types of securi-
 ties because of their characteristics and lower trading volumes.
 
 
 Risks of Foreign Investments. Certain of the Underlying Funds may invest in
 foreign securities in accordance with their investment objectives and poli-
 cies. Foreign investments involve special risks that are not typically asso-
 ciated with U.S. dollar denominated or quoted securities of U.S. issuers.
 Foreign investments may be affected by changes in currency rates, changes in
 foreign or U.S. laws or restrictions applicable to such investments and
 changes in exchange control regulations (e.g., currency blockage). A decline
 in the exchange rate of the currency (i.e., weakening of the currency
 against the U.S. dollar) in which a portfolio security is quoted or denomi-
 nated relative to the U.S. dollar would reduce the value of the portfolio
 security. In addition, if the currency in which an Underlying Fund receives
 dividends, interest or other payments declines in value against the U.S.
 dollar before such income is distributed as dividends to shareholders or
 converted to U.S. dollars, the Underlying Fund may have to sell portfolio
 securities to obtain sufficient cash to pay such dividends.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the Economic and Monetary Union presents unique uncer-
 tainties, including the legal treatment of certain outstanding financial
 contracts after January 1, 1999 that refer to existing currencies rather
 than the euro; the establishment and maintenance of exchange rates for cur-
 rencies being converted into the euro; the fluctuation of the euro relative
 to non-euro currencies during the transition period from January 1, 1999 to
 December 31, 2001 and beyond; whether the interest rate, tax and labor
 regimes of European countries participating in the euro will converge over
 time; and whether the conversion of the currencies of other coun-
 
                                                                              49

 tries that may in the future become members of the European Union may have
 an impact on the euro. These or other factors, including political and eco-
 nomic risks, could cause market disruptions, and could adversely affect the
 value of securities held by the Underlying Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States. In addition, clearance and settlement procedures
 may be different in foreign countries and, in certain markets, such proce-
 dures have been unable to keep pace with the volume of securities transac-
 tions, thus making it difficult to conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Efforts in foreign countries to remediate potential Year 2000 prob-
 lems are not as extensive as those in the United States. As a result, the
 operations of foreign markets, foreign issuers and foreign governments may
 be disrupted by the Year 2000 Problem, and the investment portfolio of an
 Underlying Fund may be adversely affected. Furthermore, with respect to cer-
 tain foreign countries, there is a possibility of nationalization, expropri-
 ation or confiscatory taxation, imposition of withholding or other taxes on
 dividend or interest payments (or, in some cases, capital gains), limita-
 tions on the removal of funds or other assets of the Underlying Funds, and
 political or social instability or diplomatic developments which could
 affect investments in those countries.
 
 Concentration of an Underlying Fund's assets in one or a few countries and
 currencies will subject a Fund to greater risks than if an Underlying Fund's
 assets were not geographically concentrated.
 
 Investment in sovereign debt obligations by certain Underlying Funds
 involves risks not present in debt obligations of corporate issuers. The
 issuer of the debt or the governmental authorities that control the repay-
 ment of the debt may be unable or unwilling to repay principal or pay inter-
 est when due in accordance with the terms of such debt, and an Underlying
 Fund may have limited recourse to compel payment in the event of a default.
 Periods of economic uncertainty may result in volatility of market prices of
 sovereign debt, and in turn an Underlying Fund's NAV, to a greater extent
 than the volatility inherent in debt obligations of U.S. issuers.

 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Underlying Funds may also invest in European
 Depository Receipts ("EDRs") or other similar instruments representing secu-
 rities of foreign issuers. ADRs represent the right to receive securities of
 foreign issuers deposited in a domestic bank or a correspondent bank. Prices
 of ADRs are quoted in U.S. dollars, and ADRs are traded in the United
 States. EDRs and GDRs are receipts
 evidencing an arrangement with a non-U.S. bank. EDRs and GDRs are not neces-
 sarily quoted in the same currency as the underlying security.
 
 Risks of Emerging Countries. Certain Underlying Funds may invest in securi-
 ties of issuers located in emerging countries. The risks of foreign invest-
 ment are heightened when the issuer is located in an emerging country.
 Emerging countries are generally located in the Asia-Pacific region, Eastern
 Europe, Latin and South America and Africa. An Underlying Fund's purchase
 and sale of portfolio securities in certain emerging countries may be con-
 strained by limitations as to daily changes in the prices of listed securi-
 ties, periodic trading or settlement volume and/or limitations on aggregate
 holdings of foreign investors. Such limitations may be computed based on the
 aggregate trading volume by or holdings of an Underlying Fund, the invest-
 ment adviser, its affiliates and their respective clients and other service
 providers. An Underlying Fund may not be able to sell securities in circum-
 stances where price, trading or settlement volume limitations have been
 reached.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by an Underlying Fund. The repatria-
 
                                                                              51

 tion of both investment income and capital from certain emerging countries
 is subject to restrictions such as the need for governmental consents. Due
 to restrictions on direct investment in equity securities in certain Asian
 countries, it is anticipated that an Underlying Fund may invest in such
 countries through other investment funds in such countries.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant invest-
 ment losses. Investing in emerging countries involves greater risk of loss
 due to expropriation, nationalization, confiscation of assets and property
 or the imposition of restrictions on foreign investments and on repatriation
 of capital invested.
 
 An Underlying Fund's investment in emerging countries may also be subject to
 withholding or other taxes, which may be significant and may reduce the
 return from an investment in such country to the Underlying Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve an Under-
 lying Fund's delivery of securities before receipt of payment for their
 sale. In addition, significant delays are common in certain markets in reg-
 istering the transfer of securities. Settlement or registration problems may
 make it more difficult for an Underlying Fund to value its portfolio securi-
 ties and could cause the Underlying Fund to miss attractive investment
 opportunities, to have a portion of its assets uninvested or to incur losses
 due to the failure of a counterparty to pay for securities the Underlying
 Fund has delivered or the Underlying Fund's inability to complete its con-
 tractual obligations. The creditworthiness of the local securities firms
 used by the Underlying Funds in emerging countries may not be as sound as
 the creditworthiness of firms used in more developed countries. As a result,
 the Under-

                                                                      APPENDIX A
 
 lying Fund may be subject to a greater risk of loss if a securities firm
 defaults in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make an Underlying Fund's investments in such countries less liq-
 uid and more volatile than investments in countries with more developed
 securities markets (such as the United States, Japan and most Western Euro-
 pean countries). An Underlying Fund's investments in emerging countries are
 subject to the risk that the liquidity of a particular investment, or
 investments generally, in such countries will shrink or disappear suddenly
 and without warning as a result of adverse economic, market or political
 conditions, or adverse investor perceptions, whether or not accurate.
 Because of the lack of sufficient market liquidity, an Underlying Fund
 may incur losses because it will be required to effect sales at a disadvan-
 tageous time and then only at a substantial drop in price. Investments in
 emerging countries may be more difficult to price precisely because of the
 characteristics discussed above and lower trading volumes.
 
 An Underlying Fund's use of foreign currency management techniques in emerg-
 ing countries may be limited. Due to the limited market for these instru-
 ments in emerging countries, the investment adviser does not currently
 anticipate that a significant portion of the Underlying Funds' currency
 exposure in emerging countries, if any, will be covered by such instruments.
 
 Risks of Derivative Investments. An Underlying Fund's transactions, if any,
 in options, futures, options on futures, swaps, interest rate caps, floors
 and collars, structured securities, inverse floating-rate securities,
 stripped mortgage-backed securities and currency transactions involve addi-
 tional risk of loss. Loss can result from a lack of correlation between
 changes in the value of derivative instruments and the portfolio assets (if
 any) being hedged, the potential illiquidity of the markets for derivative
 instruments, or the risks arising from margin requirements and related lev-
 erage factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the investment adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. The Underlying Funds may also invest in derivative
 investments for non-hedging purposes (that is, to seek to increase total
 return). Investing for non-hedging purposes is considered a speculative
 practice and presents even greater risk of loss.
 
 Derivative mortgage-backed securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact the cash flow and the market value of these securi-
 ties. In general, the risk of faster
 
                                                                              53
<PAGE>
 
 
 than anticipated prepayments adversely affects IOs, super floaters and pre-
 mium priced mortgage-backed securities. The risk of slower than anticipated
 prepayments generally adversely affects POs, floating-rate securities sub-
 ject to interest rate caps, support tranches and discount priced mortgage-
 backed securities. In addition, particular derivative securities may be
 leveraged such that their exposure (i.e., price sensitivity) to interest
 rate and/or prepayment risk is magnified.
 
 Some floating-rate derivative debt securities can present more complex types
 of derivative and interest rate risks. For example, range floaters are sub-
 ject to the risk that the coupon will be reduced below market rates if a
 designated interest rate floats outside of a specified interest rate band or
 collar. Dual index or yield curve floaters are subject to lower prices in
 the event of an unfavorable change in the spread between two designated
 interest rates.
 
 Risks of Illiquid Securities. The Underlying Funds may invest up to 15% (10%
 in the case of the Financial Square Prime Obligations Fund) of their net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
  .Both domestic and foreign securities that are not readily marketable
  .Certain municipal leases and participation interests
  .Certain stripped mortgage-backed securities
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain over-the-counter options
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that
   the restricted security is eligible for resale pursuant to Rule 144A
   under the Securities Act of 1933 ("144A Securities") and, therefore, is
   liquid.
 
 Investing in 144A Securities may decrease the liquidity of an Underlying
 Fund's portfolio to the extent that qualified institutional buyers become
 for a time uninterested in purchasing these restricted securities. The pur-
 chase price and subsequent valuation of restricted and illiquid securities
 normally reflect a discount, which may be significant, from the market price
 of comparable securities for which a liquid market exists.
 
 Credit Risks. Debt securities purchased by the Underlying Funds may include
 securities (including zero coupon bonds) issued by the U.S. government (and
 its agencies, instrumentalities and sponsored enterprises), foreign govern-
 ments, domestic and foreign corporations, banks and other issuers. Some of
 these fixed-income securities are described in the next section below. Fur-
 ther information is provided in the Additional Statement.

                                                                      APPENDIX A
 
 Debt securities rated BBB or higher by Standard & Poor's Ratings Group
 ("Standard & Poor's") or Baa or higher by Moody's Investors Services, Inc.
 ("Moody's") are considered "investment grade." Securities rated BBB or Baa
 are considered medium-grade obligations with speculative characteristics,
 and adverse economic conditions or changing circumstances may weaken their
 issuers' capacity to pay interest and repay principal. A security will be
 deemed to have met a rating requirement if it receives the minimum required
 rating from at least one such rating organization even though it has been
 rated below the minimum rating by one or more other rating organizations, or
 if unrated by such rating organizations, is determined by the Investment
 Adviser to be of comparable credit quality. If a security satisfies an
 Underlying Fund's minimum rating criteria at the time of purchase and is
 subsequently downgraded below such rating, the Underlying Fund will not be
 required to dispose of such security. If a downgrade occurs, the Underlying
 Fund's investment adviser will consider what action, including the sale of
 such security, is in the best interest of the Underlying Fund and its share-
 holders.
 
 Certain Underlying Funds may invest in fixed-income securities rated BB or
 Ba or below (or comparable unrated securities) which are commonly referred
 to as "junk bonds." Junk bonds are considered predominantly speculative and
 may be questionable as to principal and interest payments.
 
 In some cases, junk bonds may be highly speculative, have poor prospects for
 reaching investment grade standing and be in default. As a result, invest-
 ment in such bonds will present greater speculative risks than those associ-
 ated with investment in investment grade bonds. Also, to the extent that the
 rating assigned to a security in an Underlying Fund's portfolio is down-
 graded by a rating organization, the market price and liquidity of such
 security may be adversely affected.
 
 Non-Diversification and Geographic Risks. The Global Income Fund is regis-
 tered as a "non-diversified" fund under the Act and is, therefore, more sus-
 ceptible to adverse developments affecting any single issuer. In addition,
 the Global Income Fund, and certain other Underlying Funds, may invest more
 than 25% of their total assets in the securities of corporate and governmen-
 tal issuers located in a particular foreign country or region. Concentration
 of the investments of these or other Underlying Funds in issuers located in
 a particular country or region will subject the Underlying Fund, to a
 greater extent than if investments were less concentrated, to losses arising
 from adverse developments affecting those issuers or countries.
 
 Temporary Investment Risks. The Underlying Funds may invest a substantial
 portion, and in some cases all, of their total assets, in cash equivalents
 for temporary periods. When an Underlying Fund's assets are invested in such
 instruments, the Underlying Fund may not be achieving its investment objec-
 tive.
 
                                                                              55

 C. Investment Securities and Techniques
 
 This section provides further information on certain types of securities and
 investment techniques that may be used by the Underlying Funds, including
 their associated risks. Further information is provided in the Additional
 Statement, which is available upon request.
 
 U.S. Government Securities and Related Custodial Receipts. Each Underlying
 Fund may invest in U.S. Government Securities and related custodial
 receipts. U.S. Government Securities include U.S. Treasury obligations and
 obligations issued or guaranteed by U.S. government agencies, instrumentali-
 ties or sponsored enterprises. U.S. Government Securities may be supported
 by (a) the full faith and credit of the U.S. Treasury (such as the Govern-
 ment National Mortgage Association ("Ginnie Mae")); (b) the right of the
 issuer to borrow from the U.S. Treasury (such as securities of the Student
 Loan Marketing Association); (c) the discretionary authority of the U.S.
 government to purchase certain obligations of the issuer (such as the Fed-
 eral National Mortgage Association ("Fannie Mae") and Federal Home Loan
 Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issuer.
 U.S. Government Securities also include Treasury receipts, zero coupon bonds
 and other stripped U.S. Government Securities, where the interest and prin-
 cipal components of stripped U.S. Government Securities are traded indepen-
 dently.
 
 Interests in U.S. Government Securities may be purchased in the form of cus-
 todial receipts that evidence ownership of future interest payments, princi-
 pal payments or both on certain notes or bonds issued or guaranteed as to
 principal and interest by the U.S. government, its agencies, instrumentali-
 ties, political subdivisions or authorities. For certain securities law pur-
 poses, custodial receipts are not considered obligations of the U.S. govern-
 ment.
 
 Mortgage-Backed Securities. The Underlying Funds (other than CORE U.S. Equi-
 ty, CORE Large Cap Growth, CORE Large Cap Value, CORE Small Cap Equity and
 CORE International Equity Funds (the "CORE Equity Funds")) may invest in
 these securities that represent direct or indirect participations in, or are
 collateralized by and payable from, mortgage loans secured by real property
 ("Mortgage-Backed Securities"). Mortgage-Backed Securities can be backed by
 either fixed rate mortgage loans or adjustable rate mortgage loans, and may
 be issued by either a governmental or non-governmental entity. Privately
 issued Mortgage-Backed Securities are normally structured with one or more
 types of "credit enhancement." However, these Mortgage-Backed Securities
 typically do not have the same credit standing as U.S. government guaranteed
 Mortgage-Backed Securities.

                                                                      APPENDIX A
 
 
 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs"), and real estate mortgage
 investment conduit ("REMIC") pass-through or participation certificates.
 CMOs provide an investor with a specified interest in the cash flow from a
 pool of underlying mortgages or of other Mortgage-Backed Securities. CMOs
 are issued in multiple classes. In most cases, payments of principal are
 applied to the CMO classes in the order of their respective stated maturi-
 ties, so that no principal payments will be made on a CMO class until all
 other classes having an earlier stated maturity date are paid in full. A
 REMIC is a CMO that qualifies for special tax treatment and invests in cer-
 tain mortgages principally secured by interests in real property and other
 permitted investments. Mortgage-Backed Securities also include stripped
 Mortgage-Backed Securities ("SMBS"), which are derivative multiple class
 Mortgage-Backed Securities. SMBS are usually structured with two different
 classes: one that receives 100% of the interest payments and the other that
 receives 100% of the principal payments from a pool of mortgage loans. The
 market value of SMBS consisting entirely of principal payments generally is
 unusually volatile in response to changes in interest rates. The yields on
 SMBS that receive all or most of the interest from mortgage loans are gener-
 ally higher than prevailing market yields on other Mortgage-Backed Securi-
 ties because their cash flow patterns are more volatile and there is a
 greater risk that the initial investment will not be fully recouped.
 
 Asset-Backed Securities. The Underlying Funds (other than the CORE Equity
 Funds) may also invest in asset-backed securities. Asset-backed securities
 are securities whose principal and interest payments are collateralized by
 pools of assets such as auto loans, credit card receivables, leases,
 installment contracts and personal property. Asset-backed securities are
 often subject to more rapid repayment than their stated maturity date would
 indicate as a result of the pass-through of prepayments of principal on the
 underlying loans. During periods of declining interest rates, prepayment of
 loans underlying asset-backed securities can be expected to accelerate.
 Accordingly, an Underlying Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. Asset-backed securities present credit risks
 that are not presented by Mortgage-Backed Securities. This is because asset-
 backed securities generally do not have the benefit of a security interest
 in collateral that is comparable in quality to mortgage assets. There is the
 possibility that, in some cases, recoveries on repossessed collateral may
 not be available to support payments on these securities. In the event of a
 default, an Underlying Fund may suffer a loss if it cannot sell collateral
 quickly and receive the amount it is owed.
 
                                                                              57
<PAGE>
 
 
 
 Municipal Securities. Certain Underlying Funds may invest in securities and
 instruments issued by state and local governmental issuers. Municipal secu-
 rities consist of bonds, notes, commercial paper and other instruments (in-
 cluding participation interests in such securities) issued by or on behalf
 of states, territories and possessions of the United States (including the
 District of Columbia) and their political subdivisions, agencies or instru-
 mentalities. Such securities may pay fixed, variable or floating rates of
 interest. Municipal securities are often issued to obtain funds for various
 public purposes, including the construction of a wide range of public facil-
 ities such as bridges, highways, housing, hospitals, mass transportation,
 schools, streets and water and sewer works. Other public purposes for which
 municipal securities may be issued include refunding outstanding obliga-
 tions, obtaining funds for general operating expenses, and obtaining funds
 to lend to other public institutions and facilities. Municipal securities in
 which the Underlying Funds may invest include private activity bonds, munic-
 ipal leases, certificates of participation, pre-refunded municipal securi-
 ties and auction rate securities.
 
 Corporate and Bank Obligations; Trust Preferred Securities; Convertible
 Securities. Certain Underlying Funds may invest in corporate debt obliga-
 tions, trust preferred securities and convertible securities. Corporate debt
 obligations include bonds, notes, debentures and other obligations of U.S.
 or foreign corporations to pay interest and repay principal, and include
 securities issued by banks and other financial institutions. Banks are sub-
 ject to extensive but different governmental regulations which may limit
 both the amount and types of loans which may be made and interest rates
 which may be charged. In addition, the profitability of the banking industry
 is largely dependent upon the availability and cost of funds for the purpose
 of financing lending operations under prevailing money market conditions.
 General economic conditions as well as exposure to credit losses arising
 from possible financial difficulties of borrowers play an important part in
 the operation of this industry. A trust preferred or capital security is a
 long dated bond (for example, 30 years) with preferred features. The pre-
 ferred features are that payment of interest can be deferred for a specified
 period without initiating a default event. The securities are generally
 senior in claim to standard preferred stock but junior to other bondholders.
 
 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than nonconvertible securities of similar quali-
 ty. Convertible securities in which an Underlying Fund invests are subject
 to the same rating criteria as its other investments in fixed-income securi-
 ties. Convertible securities have both equity and fixed-income risk charac-
 teristics. Like all fixed-income securities, the
 
58

                                                                      APPENDIX A
 
 value of convertible securities is susceptible to the risk of market losses
 attributable to changes in interest rates. Generally, the market value of
 convertible securities tends to decline as interest rates increase and, con-
 versely, to increase as interest rates decline. However, when the market
 price of the common stock underlying a convertible security exceeds the con-
 version price of the convertible security, the convertible security tends to
 reflect the market price of the underlying common stock. As the market price
 of the underlying common stock declines, the convertible security, like a
 fixed-income security, tends to trade increasingly on a yield basis, and
 thus may not decline in price to the same extent as the underlying common
 stock.
 
 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Certain Underlying Funds may invest in zero coupon, deferred interest, pay-
 in-kind and capital appreciation bonds. These securities are issued at a
 discount from their face value because interest payments are typically post-
 poned until maturity. Pay-in-kind securities are securities that have inter-
 est payable by the delivery of additional securities.The market prices of
 these securities generally are more volatile than the market prices of
 interest-bearing securities and are likely to respond to a greater degree to
 changes in interest rates than interest-bearing securities having similar
 maturities and credit quality.
 
 Rating Criteria. Except as noted below, the Underlying Equity Funds (other
 than the CORE Equity Funds, which only invest in debt instruments that are
 cash equivalents) may invest in debt securities rated at least investment
 grade at the time of investment. Investment grade debt securities are secu-
 rities rated BBB or higher by Standard & Poor's or Baa or higher by Moody's.
 The Growth and Income, Capital Growth, Small Cap Value, International Equi-
 ty, Japanese Equity, European Equity, International Small Cap, Emerging Mar-
 kets Equity, Asia Growth and Real Estate Securities Funds may invest up to
 10%, 10%, 35%, 35%, 35%, 35%, 35%, 35%, 35% and 20%, respectively, of their
 total assets in debt securities which are rated in the lowest rating catego-
 ries by Standard & Poor's or Moody's (i.e., BB or lower by Standard & Poor's
 or Ba or lower by Moody's), including securities rated D by Moody's or Stan-
 dard & Poor's. The Mid Cap Value Fund may invest up to 10% of its total
 assets in below investment grade debt securities rated B or higher by Stan-
 dard & Poor's or Moody's. Fixed-income securities rated BB or Ba or below
 (or comparable unrated securities) are commonly referred to as "junk bonds,"
 are considered predominately speculative and may be questionable as to prin-
 cipal and interest payments as described above.
 
 Structured Securities and Inverse Floaters. Certain Underlying Funds may
 invest in structured securities. Structured securities are securities whose
 value is determined by reference to changes in the value of specific curren-
 cies, interest rates,
 
                                                                              59
<PAGE>
 
 
 commodities, indices or other financial indicators (the "Reference") or the
 relative change in two or more References. The interest rate or the princi-
 pal amount payable upon maturity or redemption may be increased or decreased
 depending upon changes in the applicable Reference. Structured securities
 may be positively or negatively indexed, so that appreciation of the Refer-
 ence may produce an increase or decrease in the interest rate or value of
 the security at maturity. In addition, changes in the interest rates or the
 value of the security at maturity may be a multiple of changes in the value
 of the Reference. Consequently, structured securities may present a greater
 degree of market risk than other types of fixed-income securities, and may
 be more volatile, less liquid and more difficult to price accurately than
 less complex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.
 
 Foreign Currency Transactions. Certain Underlying Funds may, to the extent
 consistent with their investment policies, purchase or sell foreign curren-
 cies on a cash basis or through forward contracts. A forward contract
 involves an obligation to purchase or sell a specific currency at a future
 date at a price set at the time of the contract. An Underlying Fund may
 engage in foreign currency transactions for hedging purposes and to seek to
 protect against anticipated changes in future foreign currency exchange
 rates. In addition, certain Underlying Funds may also enter into such trans-
 actions to seek to increase total return, which is considered a speculative
 practice.
 
 Underlying Funds may also engage in cross-hedging by using forward contracts
 in a currency different from that in which the hedged security is denomi-
 nated or quoted if the investment adviser determines that there is a pattern
 of correlation between the two currencies. An Underlying Fund may hold for-
 eign currency received in connection with investments in foreign securities
 when, in the judgment of the investment adviser, it would be beneficial to
 convert such currency into U.S. dollars at a later date (e.g., the Invest-
 ment Adviser anticipates that the foreign currency will appreciate against
 the U.S. dollar).
 
 Currency exchange rates may fluctuate significantly over short periods of
 time, causing, along with other factors, an Underlying Fund's NAV to fluctu-
 ate. Currency exchange rates also can be affected unpredictably by the
 intervention of U.S. or foreign governments or central banks, or the failure
 to intervene, or by currency controls or political developments in the
 United States or abroad.

 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are not guaranteed by an exchange or clear-
 inghouse, a default on a contract would deprive an Underlying Fund of
 unrealized profits, transaction costs, or the benefits of a currency hedge,
 or could force the Underlying Fund to cover its purchase or sale commit-
 ments, if any, at the current market price.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Underlying Fund may
 write (sell) covered call and put options and purchase put and call options
 on any securities in which it may invest or on any securities index com-
 prised of securities in which it may invest. An Underlying Fund that invests
 in foreign securities may also purchase and sell (write) put and call
 options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of an investment adviser to manage future price fluctua-
 tions and the degree of correlation between the options and securities (or
 currency) markets. If an investment adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in an Underlying Fund's investment portfolio, the Underlying
 Fund may incur losses that it would not otherwise incur. The use of options
 can also increase an Underlying Fund's transaction costs. Options written or
 purchased by the Underlying Funds may be traded on either U.S. or foreign
 exchanges or over-the-counter. Foreign and over-the-counter options will
 present greater possibility of loss because of their greater illiquidity and
 credit risks.
 
 Yield Curve Options. Certain Underlying Funds may enter into options on the
 yield "spread" or differential between two securities. Such transactions are
 referred to as "yield curve" options. In contrast to other types of options,
 a yield curve option is based on the difference between the yields of desig-
 nated securities rather than the prices of the individual securities, and is
 settled through cash pay-
 
                                                                              61
<PAGE>
 
 
 ments. Accordingly, a yield curve option is profitable to the holder if this
 differential widens (in the case of a call) or narrows (in the case of a
 put), regardless of whether the yields of the underlying securities increase
 or decrease.
 
 The trading of yield curve options is subject to all of the risks associated
 with the trading of other types of options. In addition, however, such
 options present a risk of loss even if the yield of one of the underlying
 securities remains constant, or if the spread moves in a direction or to an
 extent which was not anticipated.
 
 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. Certain Underlying Funds may engage in
 futures transactions on both U.S. and foreign exchanges.
 
 Certain Underlying Funds may purchase and sell futures contracts, and pur-
 chase and write call and put options on futures contracts, in order to seek
 to increase total return or to hedge against changes in interest rates,
 securities prices or to the extent an Underlying Fund invests in foreign
 securities, currency exchange rates, or to otherwise manage their term
 structures, sector selection and durations in accordance with their invest-
 ment objectives and policies. An Underlying Fund may also enter into closing
 purchase and sale transactions with respect to such contracts and options.
 An Underlying Fund will engage in futures and related options transactions
 for bona fide hedging purposes as defined in regulations of the Commodity
 Futures Trading Commission or to seek to increase total return to the extent
 permitted by such regulations. An Underlying Fund may not purchase or sell
 futures contracts or purchase or sell related options to seek to increase
 total return, except for closing purchase or sale transactions, if immedi-
 ately thereafter the sum of the amount of initial margin deposits and premi-
 ums paid on the Underlying Fund's outstanding positions in futures and
 related options entered into for the purpose of seeking to increase total
 return would exceed 5% of the market value of the Underlying Fund's net
 assets.
 
 Futures contracts and related options present the following risks:
 .While an Underlying Fund may benefit from the use of futures and options on
  futures, unanticipated changes in interest rates, securities prices or cur-
  rency exchange rates may result in a poorer overall performance than if the
  Underlying Fund had not entered into any futures contracts or options
  transactions.

 .Because perfect correlation between a futures position and portfolio posi-
  tion that is intended to be protected is impossible to achieve, the desired
  protection may not be obtained and an Underlying Fund may be exposed to
  additional risk of loss.
 .The loss incurred by an Underlying Fund in entering into futures contracts
  and in writing call options on futures is potentially unlimited and may
  exceed the amount of the premium received.
 .Futures markets are highly volatile and the use of futures may increase the
  volatility of an Underlying Fund's NAV.
 .As a result of the low margin deposits normally required in futures trad-
  ing, a relatively small price movement in a futures contract may result in
  substantial losses to an Underlying Fund.
 .Futures contracts and options on futures may be illiquid, and exchanges may
  limit fluctuations in futures contract prices during a single day.
 .Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 Preferred Stock, Warrants and Rights. Certain Underlying Funds may invest in
 preferred stock, warrants and rights. Preferred stocks are securities that
 represent an ownership interest providing the holder with claims on the
 issuer's earnings and assets before common stock owners but after bond own-
 ers. Unlike debt securities, the obligations of an issuer of preferred
 stock, including dividend and other payment obligations, may not typically
 be accelerated by the holders of such preferred stock on the occurrence of
 an event of default or other non-compliance by the issuer of the preferred
 stock.
 
 Warrants and other rights are options to buy a stated number of shares of
 common stock at a specified price at any time during the life of the war-
 rant. The holders of warrants and rights have no voting rights, receive no
 dividends and have no rights with respect to the assets of the issuer.
 
 Loan Participations. Certain Underlying Funds may invest in loan participa-
 tions. A loan participation is an interest in a loan to a U.S. or foreign
 company or other borrower which is administered and sold by a financial
 intermediary. Loan participation interests may take the form of a direct or
 co-lending relationship with the corporate borrower, an assignment of an
 interest in the loan by a co-lender or another participant, or a participa-
 tion in the seller's share of the loan. When the Underlying Fund acts as co-
 lender in connection with a participation interest or when it acquires cer-
 tain participation interests, the Underlying Fund will have direct recourse
 against the borrower if the borrower fails to pay scheduled principal and
 interest. In cases where the Underlying Fund lacks direct recourse, it will
 
                                                                              63
<PAGE>
 
 
 look to the agent bank to enforce appropriate credit remedies against the
 borrower. In these cases, the Underlying Fund may be subject to delays,
 expenses and risks that are greater than those that would have been involved
 if the Underlying Fund had purchased a direct obligation (such as commercial
 paper) of such borrower. Moreover, under the terms of the loan participa-
 tion, the Underlying Fund may be regarded as a creditor of the agent bank
 (rather than of the underlying corporate borrower), so that the Underlying
 Fund may also be subject to the risk that the agent bank may become insol-
 vent.
 
 Real Estate Investment Trusts ("REITs"). The Real Estate Securities Fund
 expects to invest a substantial portion of its total assets in REITs, which
 are pooled investment vehicles that invest primarily in either real estate
 or real estate related loans. In addition, other Underlying Equity Funds may
 invest in REITs from time to time. The value of a REIT is affected by
 changes in the value of the properties owned by the REIT or securing mort-
 gage loans held by the REIT. REITs are dependent upon the ability of the
 REITs' managers, and are subject to heavy cash flow dependency, default by
 borrowers and the qualification of the REITs under applicable regulatory
 requirements for favorable federal income tax treatment. REITs are also sub-
 ject to risks generally associated with investments in real estate including
 possible declines in the value of real estate, general and local economic
 conditions, environmental problems and changes in interest rates. To the
 extent that assets underlying a REIT are concentrated geographically, by
 property type or in certain other respects, these risks may be heightened.
 Each Underlying Fund will indirectly bear its proportionate share of any
 expenses, including management fees, paid by a REIT in which it invests.
 
 Other Investment Companies. An Underlying Fund may invest in securities of
 other investment companies (including SPDRs and WEBs, as described below)
 subject to statutory limitations. These limitations include a prohibition on
 any Underlying Fund acquiring more than 3% of the voting shares of any other
 investment company, and a prohibition on investing more than 5% of an Under-
 lying Fund's total assets in securities of any one investment company or
 more than 10% of its total assets in securities of all investment companies.
 An Underlying Fund will indirectly bear its proportionate share of any man-
 agement fees and other expenses paid by such other investment companies.
 Such other investment companies will have investment objectives, policies
 and restrictions substantially similar to those of the Underlying Fund and
 will be subject to substantially the same risks.
 
 .Standard and Poor's Depository Receipts. The Underlying Equity Funds may,
  consistent with their investment policies, purchase Standard & Poor's
  Depository Receipts ("SPDRs"). SPDRs are securities traded on the American
  Stock Exchange (the "AMEX") that represent ownership in the SPDR Trust, a
  trust
 
64
<PAGE>
 
                                                                      APPENDIX A
 
  which has been established to accumulate and hold a portfolio of common
  stocks that is intended to track the price performance and dividend yield
  of the S&P 500. SPDR Trust is sponsored by a subsidiary of the AMEX. SPDRs
  may be used for several reasons, including, but not limited to, facilitat-
  ing the handling of cash flows or trading, or reducing transaction costs.
  The price movement of SPDRs may not perfectly parallel the price action of
  the S&P 500.
 
 .World Equity Benchmark Shares. World Equity Benchmark Shares ("WEBS") are
  shares of an investment company that invests substantially all of its
  assets in securities included in the MSCI indices for specified countries.
  WEBS are listed on the AMEX and were initially offered to the public in
  1996. The market prices of WEBS are expected to fluctuate in accordance
  with both changes in the NAVs of their underlying indices and supply and
  demand of WEBS on the AMEX. To date, WEBS have traded at relatively modest
  discounts and premiums to their NAVs. However, WEBS have a limited operat-
  ing history and information is lacking regarding the actual performance and
  trading liquidity of WEBS for extended periods or over complete market
  cycles. In addition, there is no assurance that the requirements of the
  AMEX necessary to maintain the listing of WEBS will continue to be met or
  will remain unchanged. In the event substantial market or other disruptions
  affecting WEBS should occur in the future, the liquidity and value of an
  Underlying Equity Fund's shares could also be substantially and adversely
  affected. If such disruptions were to occur, an Underlying Equity Fund
  could be required to reconsider the use of WEBS as part of its investment
  strategy.
 
 Unseasoned Companies. Certain Underlying Funds may invest in companies (in-
 cluding predecessors) which have operated less than three years, except that
 this limitation does not apply to debt securities which have been rated
 investment grade or better by at least one rating organization. The securi-
 ties of such companies may have limited liquidity, which can result in their
 being priced higher or lower than might otherwise be the case. In addition,
 investments in unseasoned companies are more speculative and entail greater
 risk than do investments in companies with an established operating record.
 
 Non-Investment Grade Fixed-Income Securities. Non-investment grade fixed-
 income securities and unrated securities of comparable credit quality (com-
 monly known as "junk bonds") are considered predominantly speculative by
 traditional investment standards. In some cases, these obligations may be
 highly speculative and have poor prospects for reaching investment grade
 standing. Non-investment grade fixed-income securities are subject to the
 increased risk of an issuer's inability to meet principal and interest obli-
 gations. These securities, also referred to as high yield securities, may be
 subject to greater price volatility due to such factors as specific corpo-
 rate developments, interest rate sensitivity, negative perceptions of the
 junk bond markets generally and less secondary market liquidity.
 
                                                                              65
<PAGE>
 
 
 
 Non-investment grade fixed-income securities are generally unsecured and are
 often subordinated to the rights of other creditors of the issuers of such
 securities. Investment by an Underlying Fund in defaulted securities poses
 additional risk of loss should nonpayment of principal and interest continue
 in respect of such securities. Even if such securities are held to maturity,
 recovery by an Underlying Fund of its initial investment and any anticipated
 income or appreciation is uncertain.
 
 Equity Swaps. Each Underlying Equity Fund may invest up to 10% of its total
 assets in equity swaps. Equity swaps allow the parties to a swap agreement
 to exchange dividend income or other components of return on an equity
 investment (for example, a group of equity securities or an index) for a
 component of return on another non-equity or equity investment.
 
 An equity swap may be used by an Underlying Fund to invest in a market with-
 out owning or taking physical custody of securities in circumstances in
 which direct investment may be restricted for legal reasons or is otherwise
 impractical. Equity swaps are derivatives and their value can be very vola-
 tile. To the extent that an investment adviser does not accurately analyze
 and predict the potential relative fluctuation of the components swapped
 with another party, an Underlying Fund may suffer a loss. The value of some
 components of an equity swap (such as the dividends on a common stock) may
 also be sensitive to changes in interest rates. Furthermore, an Underlying
 Fund may suffer a loss if the counterparty defaults.
 
 When-Issued Securities and Forward Commitments. Each Underlying Fund may
 purchase when-issued securities and make contracts to purchase or sell secu-
 rities for a fixed price at a future date beyond customary settlement time.
 When-issued securities are securities that have been authorized, but not yet
 issued. When-issued securities are purchased in order to secure what is con-
 sidered to be an advantageous price and yield to the Underlying Fund at the
 time of entering into the transaction. A forward commitment involves the
 entering into a contract to purchase or sell securities for a fixed price at
 a future date beyond the customary settlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the securities
 sold may increase before the settlement date. Although an Underlying Fund
 will generally purchase securities on a when-issued or forward commitment
 basis with the intention of acquiring securities for its portfolio, an
 Underlying Fund may dispose of when-issued securities or forward commitments
 prior to settlement if its investment adviser deems it appropriate.

 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. The Underlying Funds may enter into repurchase
 agreements with dealers in U.S. Government Securities and member banks of
 the Federal Reserve System which furnish collateral at least equal in value
 or market price to the amount of their repurchase obligation. Some Under-
 lying Funds may also enter into repurchase agreements involving certain for-
 eign government securities.
 
 If the other party or "seller" defaults, an Underlying Fund might suffer a
 loss to the extent that the proceeds from the sale of the underlying securi-
 ties and other collateral held by the Underlying Fund are less than the
 repurchase price and the Underlying Fund's cost associated with delay and
 enforcement of the repurchase agreement. In addition, in the event of bank-
 ruptcy of the seller, an Underlying Fund could suffer additional losses if a
 court determines that the Underlying Fund's interest in the collateral is
 not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, an investment
 adviser will carefully consider the creditworthiness of the seller. Certain
 Underlying Funds, together with other registered investment companies having
 advisory agreements with the investment adviser or any of its affiliates,
 may transfer uninvested cash balances into a single joint account, the daily
 aggregate balance of which will be invested in one or more repurchase agree-
 ments.
 
 Lending of Portfolio Securities. Each Underlying Fund may engage in securi-
 ties lending. Securities lending involves the lending of securities owned by
 an Underlying Fund to financial institutions such as certain broker-dealers.
 The borrowers are required to secure their loans continuously with cash,
 cash equivalents, U.S. Government Securities or letters of credit in an
 amount at least equal to the market value of the securities loaned. Cash
 collateral may be invested in cash equivalents. If an investment adviser
 determines to make securities loans, the value of the securities loaned may
 not exceed 33 1/3% of the value of the total assets of an Underlying Fund
 (including the loan collateral).
 
 An Underlying Fund may lend its securities to increase its income. An Under-
 lying Fund may, however, experience delay in the recovery of its securities
 if the institution with which it has engaged in a portfolio loan transaction
 breaches its agreement with the Underlying Fund.
 
 Short Sales Against-the-Box. Certain Underlying Funds may make short sales
 against-the-box. A short sale against-the-box means that at all times when a
 short position is open the Underlying Fund will own an equal amount of secu-
 rities sold short, or securities convertible into or exchangeable for, with-
 out the payment of any further consideration, an equal amount of the securi-
 ties of the same issuer as the securities sold short.
 
                                                                              67
<PAGE>
 
 
 
 Mortgage Dollar Rolls. Certain Underlying Funds may enter into "mortgage
 dollar rolls." In mortgage dollar rolls, an Underlying Fund sells securities
 for delivery in the current month and simultaneously contracts with the same
 counterparty to repurchase substantially similar (same type, coupon and
 maturity) but not identical securities on a specified future date. During
 the roll period, the Underlying Fund loses the right to receive principal
 and interest paid on the securities sold. However, the Underlying Fund bene-
 fits to the extent of any difference between (a) the price received for the
 securities sold and (b) the lower forward price for the future purchase
 and/or fee income plus the interest earned on the cash proceeds of the secu-
 rities sold. Unless the benefits of a mortgage dollar roll exceed the
 income, capital appreciation and gain or loss due to mortgage prepayments
 that would have been realized on the securities sold as part of the roll,
 the use of this technique will diminish the Underlying Fund's performance.
 
 Successful use of mortgage dollar rolls depends upon an investment adviser's
 ability to predict correctly interest rates and mortgage prepayments. If the
 investment adviser is incorrect in its prediction, an Underlying Fund may
 experience a loss. For financial reporting and tax purposes, the Funds treat
 mortgage dollar rolls as two separate transactions: one involving the pur-
 chase of a security and a separate transaction involving a sale. The Under-
 lying Funds do not currently intend to enter into mortgage dollar rolls that
 are accounted for as a financing and do not treat them as borrowings.
 
 Borrowings and Reverse Repurchase Agreements. Each Underlying Fund can bor-
 row money from banks, and certain Underlying Funds may enter into reverse
 repurchase agreements with banks and other financial institutions in amounts
 not exceeding one-third of their total assets. Reverse repurchase agreements
 involve the sale of securities held by an Underlying Fund subject to the
 Underlying Fund's agreement to repurchase them at a mutually agreed upon
 date and price (including interest). These transactions may be entered into
 as a temporary measure for emergency purposes or to meet redemption
 requests. Reverse repurchase agreements may also be entered into when the
 investment adviser expects that the interest income to be earned from the
 investment of the transaction proceeds will be greater than the related
 interest expense. Borrowings and reverse repurchase agreements involve
 leveraging. If the securities held by an Underlying Fund decline in value
 while these transactions are outstanding, the NAV of the Underlying Fund's
 outstanding shares will decline in value by proportionately more than the
 decline in value of the securities. In addition, reverse repurchase agree-
 ments involve the risk that any interest income earned by an Underlying Fund
 (from the investment of the proceeds) will be less than the interest expense
 of the transaction, that the market value of the securities sold by an
 Underlying Fund will

                                                                      APPENDIX A
 
 decline below the price the Underlying Fund is obligated to pay to repur-
 chase the securities, and that the securities may not be returned to the
 Underlying Fund.
 
 Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Inter-
 est Rate Caps, Floors and Collars. To the extent consistent with their
 investment policies, the Underlying Funds may enter into interest rate
 swaps, mortgage swaps, credit swaps, currency swaps and interest rate caps,
 floors and collars. Interest rate swaps involve the exchange by an Under-
 lying Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest rate swaps in that
 they represent commitments to pay and receive interest. The notional princi-
 pal amount, however, is tied to a reference pool or pools of mortgages.
 Credit swaps involve the receipt of floating or fixed rate payments in
 exchange for assuming potential credit losses of an underlying security.
 Credit swaps give one party to a transaction the right to dispose of or
 acquire an asset (or group of assets), or the right to receive or make a
 payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest rate, to receive payment of interest
 on a notional principal amount from the party selling such interest rate
 cap. The purchase of an interest rate floor entitles the purchaser, to the
 extent that a specified index falls below a predetermined interest rate, to
 receive payments of interest on a notional principal amount from the party
 selling the interest rate floor. An interest rate collar is the combination
 of a cap and a floor that preserves a certain return within a predetermined
 range of interest rates.
 
 An Underlying Fund may enter into swap transactions for hedging purposes or
 to seek to increase total return. The use of interest rate, mortgage, credit
 and currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If an investment adviser is incorrect in its forecasts of market val-
 ue, interest rates and currency exchange rates, the investment performance
 of an Underlying Fund would be less favorable than it would have been if
 these investment techniques were not used.

Financial Highlights
 
 The financial highlights tables are intended to help you understand a Port-
 folio's financial performance for the past five years (or less if the Port-
 folio has been in operation for less than five years). Certain information
 reflects financial results for a single Portfolio share. The total returns
 in the table represent the rate that an investor would have earned or lost
 on an investment in a Portfolio (assuming reinvestment of all dividends and
 distributions). This information has been audited by Arthur Andersen LLP,
 whose report, along with a Portfolio's financial statements, is included in
 the Portfolio's annual report (available upon request without charge). Dur-
 ing the period shown, the Trust did not offer the Goldman Sachs Conservative
 Strategy Portfolio. Accordingly, there are no financial highlights for this
 Portfolio.

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Funds. GSAM is referred to in this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Money Market Funds are managed to seek preservation of capital, daily
 liquidity and maximum current income. With each Fund, the Investment Adviser
 follows a conservative, risk-managed investment process that seeks to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 
 1.MANAGING CREDIT RISK
 
 The Investment Adviser's process for managing risk emphasizes:
 .INTENSIVE RESEARCH--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Funds. Sources for their
  analysis include third-party inputs, such as financial statements and media
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .TIMELY UPDATES--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 THE RESULT: AN "APPROVED" LIST OF HIGH-QUALITY CREDITS--The Investment
 Adviser's portfolio management team uses this approval list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
                                                                               1
<PAGE>
 
 
 
 2.MANAGING INTEREST RATE RISK
 
 Three main steps are followed in seeking to manage interest rate risk:
 .ESTABLISH WEIGHTED AVERAGE MATURITY (WAM) TARGET--WAM (the weighted average
  time until the yield of a portfolio reflects any changes in the current
  interest rate environment) is constantly revisited and adjusted as market
  conditions change. An overall strategy is developed by the portfolio
  management team based on insights gained from weekly meetings with both
  Goldman Sachs economists and economists from outside the firm.
 .IMPLEMENT OPTIMUM PORTFOLIO STRUCTURE--Proprietary models that seek the
  optimum balance of risk and return, in conjunction with the Investment
  Adviser's analysis of factors such as market events, short-term interest
  rates and each Fund's asset volatility, are used to identify the most
  effective portfolio structure.
 .CONDUCT RIGOROUS ANALYSIS OF NEW SECURITIES--The Investment Adviser's five-
  step process includes legal, credit, historical index and liquidity
  analysis, as well as price stress testing to determine suitability for
  money market mutual funds.
 
 3. MANAGING LIQUIDITY
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .Each Fund's clients and factors that influence their asset volatility;
 .Technical events that influence the trading range of federal funds and
  other short-term fixed-income markets; and
 .Bid-ask spreads associated with securities in the portfolios.
 
 Benchmarks for the Money Market Funds are the IBC FINANCIAL DATA UNIVERSAL
 AVERAGES. Each Fund tracks the IBC Index which best corresponds to the
 Fund's eligible investments.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 .THE FUNDS: Each Fund's securities are valued by the amortized cost method
  as permitted by Rule 2a-7 under the Investment Company Act of 1940, as
  amended (the "Act"). Under Rule 2a-7, each Fund may invest only in U.S.
  dollar-denominated securities that are determined to present minimal credit
  risk and meet certain other criteria, including conditions relating to
  maturity, diversification and credit quality. These operating policies may
  be more restrictive than the fundamental policies set forth in the State-
  ment of Additional Information (the "Additional Statement").
  .TAXABLE FUNDS: Prime Obligations, Money Market, Premium Money Market,
   Treasury Obligations and Government Funds.
  .TAX-ADVANTAGED FUNDS: Treasury Instruments and Federal Funds.
  .TAX-EXEMPT FUNDS: Tax-Free Money Market and Municipal Money Market Funds.
 .THE INVESTORS: The Funds are designed for institutional investors seeking a
  high rate of return, a stable net asset value ("NAV") and convenient liqui-
  dation privileges. The Funds are particularly suitable for banks, corpora-
  tions and other financial institutions that seek investment of short-term
  funds for their own accounts or for the accounts of their customers. Shares
  of the Government Fund are intended to qualify as eligible investments for
  federally chartered credit unions pursuant to Sections 107(7), 107(8) and
  107(15) of the Federal Credit Union Act, Part 703 of the National Credit
  Union Administration ("NCUA") Rules and Regulations and NCUA Letter Number
  155. The Fund intends to review changes in the applicable laws, rules and
  regulations governing eligible investments for federally chartered credit
  unions, and to take such action as may be necessary so that the investments
  of the Fund qualify as eligible investments under the Federal Credit Union
  Act and the regulations thereunder. Shares of the Government Fund, however,
  may or may not qualify as eligible investments for particular state-chart-
  ered credit unions. A state-chartered credit union should consult qualified
  legal counsel to determine whether the Government Fund is a permissible
  investment under the law applicable to it.
 .NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
 .MAXIMUM REMAINING MATURITY OF PORTFOLIO INVESTMENTS: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .DOLLAR-WEIGHTED AVERAGE PORTFOLIO MATURITY ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .INVESTMENT RESTRICTIONS: Each Fund is subject to certain investment
  restrictions that are described in detail under "Investment Restrictions"
  in the Additional
 
                                                                               3

  Statement. Fundamental investment restrictions of a Fund cannot be changed
  without approval of a majority of the outstanding shares of that Fund. The
  Treasury Obligations Fund's policy of limiting its investments to U.S.
  Treasury Obligations (as defined in Appendix A) and related repurchase
  agreements is also fundamental. All investment objectives and policies not
  specifically designated as fundamental are non-fundamental and may be
  changed without shareholder approval.
 .DIVERSIFICATION: Diversification can help a Fund reduce the risks of
  investing. In accordance with current regulations of the Securities and
  Exchange Commission (the "SEC"), each Fund may not invest more than 5% of
  the value of its total assets at the time of purchase in the securities of
  any single issuer. However, a Fund may invest up to 25% of the value of the
  total assets in the securities of a single issuer for up to three business
  days. These limitations do not apply to cash, certain repurchase agree-
  ments, U.S. Government Securities (as defined in Appendix A) or securities
  of other investment companies. In addition, securities subject to certain
  unconditional guarantees and securities that are not "First Tier Securi-
  ties" as defined by the SEC are subject to different diversification
  requirements as described in the Additional Statement.

Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 The Prime Obligations, Money Market, Premium Money Market, Treasury Obliga-
 tions, Treasury Instruments, Government, Federal, Tax-Free Money Market and
 Municipal Money Market Funds seek to maximize current income to the extent
 consistent with the preservation of capital and the maintenance of liquidity
 by investing exclusively in high quality money market instruments.
 
 
 TAXABLE AND TAX-ADVANTAGED FUNDS:
 The Prime Obligations, Money Market and Premium Money Market Funds pursue
 their investment objectives by investing in U.S. Government Securities,
 obligations of U.S. banks, commercial paper and other short-term obligations
 of U.S. companies, states, municipalities and other entities and repurchase
 agreements. The Money Market and Premium Money Market Funds may also invest
 in U.S. dollar denominated obligations of foreign banks, foreign companies
 and foreign governments. The Treasury Obligations Fund pursues its invest-
 ment objective by investing in securities issued by the U.S. Treasury and
 repurchase agreements relating to such securities. The Government Fund pur-
 sues its investment objective by investing in securities issued by the U.S.
 Government, its agencies, authorities and instrumentalities and repurchase
 agreements relating to such securities. The Treasury Instruments and Federal
 Funds pursue their investment objectives by limiting their investments to
 certain U.S. Treasury Obligations and U.S. Government Securities, respec-
 tively, the interest from which is generally exempt from state income taxa-
 tion. You should consult your tax adviser to determine whether distributions
 from the Treasury Instruments and Federal Funds (and any other Fund that may
 hold such obligations) derived from interest on such obligations are exempt
 from state income taxation in your own state.
 
 In order to obtain a rating from a rating organization, the Prime Obliga-
 tions, Money Market, Premium Money Market, Treasury Obligations, Treasury
 Instruments, Government and Federal Funds will observe special investment
 restrictions.
 
 TAX-EXEMPT FUNDS:
 The Tax-Free Money Market and Municipal Money Market Funds pursue their
 investment objectives by investing in securities issued by or on behalf of
 states, territories, and possessions of the United States and their politi-
 cal subdivisions, agencies, authorities and instrumentalities, and the Dis-
 trict of Columbia, the interest from which, if any, is in the opinion of
 bond counsel excluded from gross income for federal income tax purposes, and
 with respect to the Tax-Free Money Market Fund, not an item of tax prefer-
 ence under the federal alternative minimum tax ("AMT"). With respect to the
 Municipal Money Market Fund, such interest may not necessarily be exempt
 from the AMT.

 PRINCIPAL INVESTMENT STRATEGIES
 
 The table below identifies some of the investment techniques that may (but
 are not required to) be used by the Funds in seeking to achieve their
 investment objectives. The table also highlights the differences among the
 Funds in their use of these techniques and other investment practices and
 investment securities. Numbers in this table show allowable usage only; for
 actual usage, consult the Fund's annual/semiannual reports. For more infor-

 2 Including foreign branches of U.S. banks.
 3 If adverse economic conditions prevail in the banking industry (such as
   substantial losses on loans, increases in non-performing assets and charge-
   offs and declines in total deposits) the Funds may, for temporary defensive
   purposes, invest less than 25% of their total assets in bank obligations.
 4 Issued by the U.S. Treasury.
 5 To the extent required by Rule 2a-7, asset-backed and receivables-backed
   securities will be rated by the requisite number of nationally recognized
   statistical rating organizations ("NRSROs").
 6 The Funds may invest in U.S. dollar-denominated obligations (limited to
   commercial paper and other notes) issued or guaranteed by a foreign
   government. The Funds may also invest in U.S. dollar-denominated
   obligations issued or guaranteed by any entity located or organized in a
   foreign country that maintains a short-term foreign currency rating in the
   highest short-term ratings category by the requisite number of NRSRO's. The
   Funds may not invest more than 25% of their total assets in the securities
   of any one foreign government.

 7 Will only make such investments when yields on such securities are
   attractive compared to other taxable investments.
 8 Ordinarily expect that 100% of a Fund's portfolio securities will be
   invested in municipal obligations, but the Funds may, for temporary
   defensive purposes, hold cash or invest in short-term taxable securities.
 9 To the extent permitted by Rule 2a-7, securities without short-term ratings
   may be purchased if they are deemed to be of comparable quality to First
   Tier Securities, or to the extent that a Fund may purchase Second Tier
   Securities, comparable in quality to Second Tier Securities. In addition, a
   Fund holding a security supported by a guarantee or demand feature may rely
   on the credit quality of the guarantee or demand feature in determining the
   credit quality of the investment.
 10 If such policy should change, private activity bonds subject to AMT would
    not exceed 20% of a Fund's net assets under normal market conditions.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

Risks that apply to all Funds:
 
 .NAV RISK--The risk that a Fund will not be able to maintain a NAV per share of
 $1.00 at all times.
 .INTEREST RATE RISK--The risk that during periods of rising interest rates, a
 Fund's yield (and the market value of its securities) will tend to be lower
 than prevailing market rates; in periods of falling interest rates, a Fund's
 yield will tend to be higher.
 .CREDIT/DEFAULT RISK--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Free Money Market and Municipal Money Market Funds, risk of loss from pay-
 ment default may also exist where municipal instruments are backed by foreign
 letters of credit or guarantees.
 .LIQUIDITY RISK--The risk that a Fund will be unable to pay redemption proceeds
 within the time period stated in this Prospectus, because of unusual market
 conditions, an unusually high volume of redemption requests, or other reasons.
 .OTHER RISKS--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Risk that applies to the Prime Obligations, Money Market, Premium Money Market,
Government and Federal Funds:
 
 .U.S. GOVERNMENT SECURITIES RISK--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market and Premium Money Market Funds:
 
 .FOREIGN RISK--The risk that a foreign security could lose value as a result of
 political, financial and economic events in foreign countries, less publicly
 available financial and other information, less stringent foreign securities
 regulations and accounting and disclosure standards, or other factors. The
 Money Market and Premium Money Market Funds may not invest more than 25% of
 their total assets in the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
 .BANKING INDUSTRY RISK--The risk that if a Fund invests more than 25% of its
 total assets in bank obligations, an adverse development in the banking indus-
 try may affect the value of the Fund's investments more than if a Fund's
 investments were not invested to such a degree in the banking industry. Nor-
 mally, the Money Market and Premium Money Market Funds intend to invest more
 than 25% of their total assets in bank obligations. Banks may be particularly
 susceptible to certain economic factors such as interest rate changes, adverse
 developments in the real estate market, fiscal and monetary policy and general
 economic cycles.
 
Risks that apply to the Tax-Exempt Funds:
 
 .CONCENTRATION RISK--The risk that if a Fund invests more than 25% of its total
 assets in issuers within the same state, industry or economic sector, an
 adverse economic, business or political development may affect the value of
 the Fund's investments more than if its investments were not so concentrated.
 .TAX RISK--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of a Fund to pay federal tax-
 exempt dividends.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's FST
 Shares from year to year; and (b) the average annual returns of a Fund's FST
 Shares. Investors should be aware that the fluctuation of interest rates is
 one primary factor in performance volatility. The bar chart and table assume
 reinvestment of dividends and distributions. A Fund's past performance is
 not necessarily an indication of how the Fund will perform in the future.
 Performance reflects expense limitations in effect. If expense limitations
 were not in place, a Fund's performance would have been reduced. You may
 obtain a Fund's current yield by calling 1-800-621-2550. No information has
 been provided for the Municipal Money Market Fund because it has not yet
 commenced operations.

Fund Fees and Expenses continued
 
/1/The Funds' annual operating expenses are based on actual expenses, except
for the Municipal Money Market Fund, which are based on estimated amounts for
the current fiscal year.
/2/The Investment Adviser has voluntarily agreed not to impose a portion of the
management fee on the Funds equal to 0.035% of the Funds' average daily net
assets. AS A RESULT OF FEE WAIVERS, THE CURRENT MANAGEMENT FEES OF THE FUNDS
ARE 0.17% OF THE FUNDS' AVERAGE DAILY NET ASSETS. THE WAIVERS MAY BE TERMINATED
AT ANY TIME AT THE OPTION OF THE INVESTMENT ADVISER.
/3/The Investment Adviser has voluntarily agreed to reduce or limit "Other

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in FST
Shares of a Fund for the time periods indicated and then redeem all of your
shares at the end of those periods. The Example also assumes that your invest-
ment has a 5% return each year and that a Fund's operating expenses remain the
same. Although your actual costs may be higher or lower, based on these assump-
tions your costs would be:

Institutions that invest in FST Shares on behalf of their customers may charge
other fees directly to their customer accounts in connection with their invest-
ments. You should contact your institution for information regarding such
charges. Such fees, if any, may affect the return their customers realize with
respect to their investment.
 
Certain institutions that invest in FST Shares on behalf of their customers may
receive other compensation in connection with the sale and distribution of such
shares or for services to their customers' accounts and/or the Funds. For addi-
tional information regarding such compensation, see "Shareholder Guide" in the
Prospectus and "Other Information" in the Additional Statement.

 INVESTMENT ADVISER
 
 
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. The Goldman Sachs Group,
 L.P., which controls the Investment Adviser announced that it will pursue an

 together with its affiliates, acted as investment adviser or distributor for
 assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
 .Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
 .Administers each Fund's business affairs
 .Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
                                                                              29

 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-

 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.

Dividends
 
 
Dividends will be distributed to shareholders monthly. You may choose to have
dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time. If you do not indicate any
choice, your dividends and distributions will be reinvested automatically in
the applicable Fund.
 
All or substantially all of each Fund's net investment income will be declared
as a dividend daily. Dividends will normally, but not always, be declared as of
the following times:

Dividends will be reinvested as of the last calendar day of each month. Cash
distributions normally will be paid on or about the first business day of each
month. Net short-term capital gains, if any, will be distributed in accordance
with federal income tax requirements and may be reflected in a Fund's daily
distributions.
 
Each Fund may distribute at least annually other realized capital gains, if
any, after reduction by available capital losses. In order to avoid excessive
fluctuations in the amount of monthly capital gains distributions, a portion of
any net capital gains realized on the disposition of securities during the
months of November and December may be distributed during the subsequent calen-
dar year. Although realized gains and
 
                                                                              31

losses on the assets of a Fund are reflected in the NAV of the Fund, they are
not expected to be of an amount which would affect the Fund's NAV of $1.00 per
share.
 
The income declared as a dividend for the Prime Obligations, Treasury Obliga-
tions, Government and Premium Money Market Funds is based on estimates of net
investment income for each Fund. Actual income may differ from estimates, and
differences, if any, will be included in the calculation of subsequent divi-
dends.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' FST Shares.
 
 HOW TO BUY SHARES
 
 How Can I Purchase FST Shares Of The Funds?
 You may purchase FST Shares on any business day at their NAV next determined
 after receipt of an order. Shares begin earning dividends after the receipt
 of the purchase amount in federal funds. No sales load is charged. You may
 place a purchase order in writing or by telephone.

 In order to make an initial investment in a Fund, you must furnish to the
 Fund or Goldman Sachs the Account Application attached to this Prospectus.
 
 You may send your payment as follows:
 .Wire federal funds to The Northern Trust Company ("Northern"), as sub-cus-
  todian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); OR
 .Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; OR
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds -(Name
  of Fund and Class of Shares), 4900 Sears Tower-60th Floor, Chicago, IL
  60606-6372. The Funds will not accept a check drawn on a foreign bank or a
  third-party check.
 
 IT IS STRONGLY RECOMMENDED THAT PAYMENT BE EFFECTED BY WIRING FEDERAL FUNDS
 TO NORTHERN.
 
                                                                              33
<PAGE>
 
 
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.

 How Do I Purchase Shares Through A Financial Institution?
 Certain institutions (including banks, trust companies, brokers and invest-
 ment advisers) that provide recordkeeping, reporting and processing services
 to their customers may be authorized to accept, on behalf of the Trust, pur-
 chase, redemption and exchange orders placed by or on behalf of their cus-
 tomers and may designate other intermediaries to accept such orders, if
 approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized institution or intermediary on a busi-
  ness day, and the order will be priced at the Fund's NAV next determined
  after such acceptance.
 .Authorized institutions or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your institution or intermediary directly to learn
 whether it is authorized to accept orders for the Trust.

 These institutions may receive payments from the Funds or Goldman Sachs for
 the services provided by them with respect to the Funds' FST Shares. These
 payments may be in addition to other payments borne by the Funds.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to certain institutions and other persons in
 connection with the sale, distribution and/or servicing of shares of the
 Funds and other Goldman Sachs Funds. Subject to applicable NASD regulations,
 the Investment Adviser, Distributor and/or their affiliates may also con-
 tribute to various cash and non-cash incentive arrangements to promote the
 sale of shares. This additional compensation can vary among institutions
 depending upon such factors as the amounts their customers have invested (or
 may invest) in particular Goldman Sachs Funds, the particular program
 involved, or the amount of reimbursable expenses.
 
 In addition to FST Shares, each Fund also offers other classes of shares to
 investors. These other share classes are subject to different fees and
 expenses (which affect performance), and are entitled to different services
 than FST Shares. Information regarding these other share classes may be
 obtained from your sales representative or from Goldman Sachs by calling the
 number on the back cover of this Prospectus.

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment and minimum account balance require-
  ment.
 .Reject any purchase order for any reason.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
                                                                              35
<PAGE>
 
 
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange FST Shares is
 determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                             (Value of Assets of the Class)
                              - (Liabilities of the Class)
                   NAV = _________________________________________

 .NAV per share of each class is calculated by State Street on each business
  day. Fund shares will be priced on any day the New York Stock Exchange is
  open, except for days on which Chicago, Boston or New York banks are closed
  for local holidays.
 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell FST Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. GENERALLY, EACH FUND WILL REDEEM ITS FST SHARES
 UPON REQUEST ON ANY BUSINESS DAY AT THEIR NAV NEXT DETERMINED AFTER RECEIPT

 Certain institutions and intermediaries are authorized to accept redemption
 requests on behalf of the Funds as described under "How Do I Purchase Shares
 Through A Financial Institution?" A redemption may also be made with respect
 to certain Funds by means of the check redemption privilege described in the
 Additional Statement.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 NOTE: IT MAY BE DIFFICULT TO MAKE TELEPHONE REDEMPTIONS IN TIMES OF DRASTIC
 ECONOMIC OR MARKET CONDITIONS.

 .Although redemption proceeds will normally be wired as described above,
  each Fund reserves the right to pay redemption proceeds up to three busi-
  ness days following receipt of a properly executed wire transfer redemption
  request. If you are selling shares you recently paid for by check, the Fund
  will pay you when your check has cleared, which may take up to 15 days. If
  the Federal Reserve Bank is closed on the day that the redemption proceeds
  would ordinarily be wired, wiring the redemption proceeds may be delayed
  one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  Account Application to the Transfer Agent.

 .Neither the Trust nor Goldman Sachs assumes any responsibility for the per-
  formance of your bank or any intermediaries in the transfer process. If a
  problem with such performance arises, you should deal directly with your
  bank or any such intermediaries.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption request:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 
 The Trust reserves the right to:
 .Redeem your shares if your account balance falls below the minimum as a
  result of a redemption. The Fund will give you 60 days' prior written
  notice to allow you to purchase sufficient additional shares of the Fund in
  order to avoid such redemption.
 .Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash
  from the Fund). If you receive redemption proceeds in-kind, you should
  expect to incur transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange FST Shares of a Fund at NAV for shares of the corresponding
 class of any other Goldman Sachs Fund. The exchange privilege may be materi-
 ally modified or withdrawn at any time upon 60 days' written notice to you.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  to Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will I Be Sent Regarding Investments In FST Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-621-2550. You will also be provided with an
 individual monthly statement. Upon request, you will be provided with a
 printed confirmation for each transaction in your account. Any dividends and
 distributions paid by the Funds are also reflected in regular statements
 issued by the Funds to recordholders.

Taxation
 
 
Each Fund intends to qualify as a regulated investment company for federal tax
purposes, and to distribute to shareholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Funds, Fund dividends will generally be taxable to
you as ordinary income (unless your investment is in an IRA or other tax-
advantaged account) regardless of whether you reinvest in additional shares or
take them as cash. The Tax-Exempt Funds expect generally to distribute "exempt-
interest dividends," which will be tax-exempt income for federal income tax
purposes. The tax status and amounts of the dividends for each calendar year
will be detailed in your annual tax statement from the Funds.
 
Dividends and distributions from each Fund will generally be taxable to you in
the tax year in which they are paid, with one exception. Dividends and distri-
butions declared by a Fund in October, November or December and paid in January
are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry shares of the
Tax-Exempt Funds generally will not be deductible for federal income tax pur-
poses.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Funds may be an item of tax preference for purposes of determining
your AMT liability. Exempt-interest dividends will also be considered along
with other adjusted gross income in determining whether any social security or
railroad retirement payments received by you are subject to federal income tax-
es.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from any Fund (including the Tax-Exempt Funds)
or on the value of the shares held by you. More tax information is provided in
the Additional Statement. You should also consult your own tax adviser for
information regarding all tax consequences applicable to your investments in
the Funds.

Appendix A
Additional Information on Portfolio
Risks, Securities and Techniques
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Funds, including their associated
risks. Additional information is provided in the Additional Statement, which is
available upon request. Among other things, the Additional Statement describes
certain fundamental policies and investment restrictions that cannot be changed
without shareholder approval. You should note, however, that all policies not
specifically designated as fundamental are non-fundamental and may be changed
without shareholder approval. If there is a change in a Fund's investment
objective, you should consider whether that Fund remains an appropriate invest-
ment in light of your then current financial position and needs.
 
U.S. TREASURY OBLIGATIONS AND U.S. GOVERNMENT SECURITIES AND RELATED CUSTODIAL
RECEIPTS. U.S. Treasury Obligations include securities issued or issued or
guaranteed by the U.S. Treasury ("U.S. Treasury Obligations"). Payment of
principal and interest on these obligations is backed by the full faith and
credit of the U.S. government. U.S. Treasury Obligations include, among other
things, the separately traded principal and interest components of securities
guaranteed or issued by the U.S. Treasury if such components are traded
independently under the Separate Trading of Registered Interest and Principal
of Securities program ("STRIPS").
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury Obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.

                                                                      APPENDIX A
 
 
Some Funds invest in U.S. Treasury Obligations and certain U.S. Government
Securities the interest from which is generally exempt from state income taxa-
tion. Securities generally eligible for this exemption include those issued by
the U.S. Treasury and certain agencies, authorities or instrumentalities of the
U.S. government, including the Federal Home Loan Banks, Federal Farm Credit
Banks, Tennessee Valley Authority and Student Loan Marketing Association.
 
U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Certain Funds may also acquire U.S. Government Securities in the form of custo-
dial receipts. Custodial receipts evidence ownership of future interest pay-
ments, principal payments or both on notes or bonds issued or guaranteed as to
principal or interest by the U.S. government, its agencies, instrumentalities,
political subdivisions or authorities. For certain securities law purposes,
custodial receipts are not considered obligations of the U.S. government.
 
BANK OBLIGATIONS. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. Certain Funds may invest in obligations issued or
backed by U.S. banks when a bank has more than $1 billion in total assets at
the time of purchase or is a branch or subsidiary of such a bank. In addition,
certain Funds may invest in U.S. dollar-denominated obligations issued or
guaranteed by foreign banks that have more than $1 billion in total assets at
the time of purchase, U.S. branches of such foreign banks (Yankee obligations),
foreign branches of such foreign banks and foreign branches of U.S. banks
having more than $1 billion in total assets at the time of purchase. Bank
obligations may be general obligations of the parent bank or may be limited to
the issuing branch by the terms of the specific obligation or by government
regulation.
 
If a Fund invests more than 25% of its total assets in bank obligations
(whether foreign or domestic), it may be especially affected by favorable and
adverse developments in or related to the banking industry. The activities of
U.S. and most foreign banks are subject to comprehensive regulations which, in
the case of U.S. regulations, have undergone substantial changes in the past
decade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of opera-
tions and profitability of domestic and foreign banks. Significant developments
in the U.S. banking industry have included increased competition from other
types of financial institutions, increased acquisition activity and geographic
expansion. Banks may be particularly susceptible to certain economic factors,
such as interest rate changes and adverse developments in the real
 
                                                                              43
<PAGE>
 
 
estate markets. Fiscal and monetary policy and general economic cycles can
affect the availability and cost of funds, loan demand and asset quality and
thereby impact the earnings and financial conditions of banks.
 
COMMERCIAL PAPER. A Fund may invest in commercial paper, including variable
amount master demand notes and asset-backed commercial paper. Commercial paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, finance companies and other issuers.
The commercial paper purchased by a Fund consists of direct U.S. dollar-denomi-
nated obligations of domestic or, in the case of certain Funds, foreign
issuers.
 
SHORT-TERM OBLIGATIONS. A Fund may invest in other short-term obligations,
including short-term funding agreements payable in U.S. dollars and issued or
guaranteed by U.S. corporations, foreign corporations or other entities. A
funding agreement is a contract between an issuer and a purchaser that obli-
gates the issuer to pay a guaranteed rate of interest on a principal sum depos-
ited by the purchaser. Funding agreements will also guarantee a stream of pay-
ments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and guaran-
teed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Fund will be regarded as
illiquid.
 
ASSET-BACKED AND RECEIVABLES-BACKED SECURITIES. Certain Funds may invest in
asset-backed and receivables-backed securities whose principal and interest
payments are collateralized by pools of assets such as auto loans, credit card
receivables, leases, installment contracts and personal property. Asset-backed
and receivables-backed securities are often subject to more rapid repayment
than their stated maturity date would indicate as a result of the pass-through
of prepayments of principal on the underlying loans. During periods of
declining interest rates, prepayment of loans underlying asset-backed and
receivables-backed securities can be expected to accelerate. Accordingly, a
Fund's ability to maintain positions in such securities will be affected by
reductions in the principal amount of such securities resulting from
prepayments, and its ability to reinvest the returns of principal at comparable
yields is subject to generally prevailing interest rates at that time. In
addition, securities that are backed by credit card, automobile and similar
types of receivables generally do not have the benefit of a security interest
in collateral that is comparable in quality to mortgage assets. There is the
possibility that, in some cases, recoveries on repossessed collateral may not
be available to support payments on these securities. In the event of a
default, a Fund may suffer a loss if it cannot sell collateral quickly and
receive the amount it is owed.
 
FOREIGN GOVERNMENT OBLIGATIONS AND RELATED FOREIGN RISKS. Certain Funds may
invest in foreign government obligations. Foreign government obligations are
U.S. dollar-denominated obligations (limited to commercial paper and other
notes) issued
 
44
<PAGE>
 
                                                                      APPENDIX A
 
or guaranteed by a foreign government or other entity located or organized in a
foreign country that maintains a short-term foreign currency rating in the
highest short-term ratings category by the requisite number of NRSROs.
 
Investments by a Fund in foreign securities, whether issued by a foreign gov-
ernment, bank, corporation or other issuer, may present a greater degree of
risk than investments in securities of domestic issuers because of less public-
ly-available financial and other information, less securities regulation,
potential imposition of foreign withholding and other taxes, war, expropriation
or other adverse governmental actions. Efforts in foreign countries to remedi-
ate potential Year 2000 problems are not as extensive as those in the United
States. As a result, the operations of foreign markets, foreign issuers and
foreign governments may be disrupted by the Year 2000 Problem, and the invest-
ment portfolio of a Fund may be adversely affected. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and generally
are not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks.
 
REPURCHASE AGREEMENTS. Certain Funds may enter into repurchase agreements with
primary dealers in U.S. Government Securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund are less than the repurchase price and the Fund's
cost associated with delay and enforcement of the repurchase agreement. In
addition, in the event of bankruptcy of the seller, a Fund could suffer addi-
tional losses if a court determines that the Fund's interest in the collateral
is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, certain Funds, together with other registered
investment companies having advisory agreements with the Investment Adviser or
any of its affiliates, may transfer uninvested cash balances into a single
joint account, the daily aggregate balance of which will be invested in one or
more repurchase agreements.
 
MUNICIPAL OBLIGATIONS. Certain Funds may invest in municipal obligations.
Municipal obligations are issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies,
authorities and instrumentalities, and the District of Columbia. Municipal
obligations may include fixed rate notes and similar debt instruments; variable
and floating rate demand instruments; tax-exempt commercial paper; municipal
bonds; and unrated notes, paper, bonds or other instruments.
 
                                                                              45
<PAGE>
 
 
 
MUNICIPAL NOTES AND BONDS. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
TENDER OPTION BONDS. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Fund's average portfolio maturity. There is a risk that a Fund will not be con-
sidered the owner of a tender option bond for federal income tax purposes, and
thus will not be entitled to treat such interest as exempt from federal
income tax. Certain tender option bonds may be illiquid or may become illiquid
as a result of a credit rating downgrade, a payment default or a disqualifica-
tion from tax-exempt status.
 
REVENUE ANTICIPATION WARRANTS. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which
 
46
<PAGE>
 
                                                                      APPENDIX A
 
include a demand feature that permits the holder to sell the RAWs to a bank or
other financial institution at a purchase price equal to par plus accrued
interest on each interest rate reset date.
 
INDUSTRIAL DEVELOPMENT BONDS. Certain Funds may invest in industrial develop-
ment bonds (private activity bonds). Industrial development bonds are a spe-
cific type of revenue bond backed by the credit and security of a private user,
the interest from which would be an item of tax preference when distributed by
a Fund as "exempt-interest dividends" to shareholders under the AMT.
 
OTHER MUNICIPAL OBLIGATION POLICIES. Certain Funds may invest 25% or more of
the value of their respective total assets in municipal obligations which are
related in such a way that an economic, business or political development or
change affecting one municipal obligation would also affect the other municipal
obligation. For example, a Fund may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of a Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political developments affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality of these banks and financial institutions could,
therefore, cause a loss to a Fund that invests in municipal obligations. Let-
ters of credit and other obligations of foreign banks and financial institu-
tions may involve risks in addition to those of domestic obligations because of
less publicly available financial and other information, less securities regu-
lation, potential imposition of foreign withholding and other taxes, war,
expropriation or other adverse governmental actions. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and are gener-
ally not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks. In addition, the Funds may acquire securities in the
form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.
 
                                                                              47
<PAGE>
 
 
 
FLOATING AND VARIABLE RATE OBLIGATIONS. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Fund may consider the maturity of a variable or floating rate obli-
gation to be shorter than its ultimate stated maturity if the obligation is a
U.S. Treasury Obligation or U.S. Government Security, if the obligation has a
remaining maturity of 397 calendar days or less, or if the obligation has a
demand feature that permits the Fund to receive payment at any time or at spec-
ified intervals not exceeding 397 calendar days. The issuers or financial
intermediaries providing demand features may support their ability to purchase
the obligations by obtaining credit with liquidity supports. These may include
lines of credit, which are conditional commitments to lend and letters of cred-
it, which will ordinarily be irrevocable, both of which may be issued by domes-
tic banks or foreign banks which have a branch, agency or subsidiary in the
United States. A Fund may purchase variable or floating rate obligations from
the issuers or may purchase certificates of participation, a type of floating
or variable rate obligation, which are interests in a pool of debt obligations
held by a bank or other financial institution.
 
WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS. The Funds may purchase when-
issued securities and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. When-issued securities
are securities that have been authorized, but not yet issued. When-issued secu-
rities are purchased in order to secure what is considered to be an advanta-
geous price and yield to a Fund at the time of entering into the transaction. A
forward commitment involves entering into a contract to purchase or sell secu-
rities for a fixed price at a future date beyond the customary settlement peri-
od.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Fund will generally purchase
securities on a when-issued or forward commitment basis with the intention of
acquiring securities for its portfolio, a Fund may dispose of when-issued secu-
rities or forward commitments prior to settlement if the Investment Adviser
deems it appropriate.
 
OTHER INVESTMENT COMPANIES. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Act. These limitations
include a prohibition on any Fund acquiring more than 3% of the voting shares
of any other investment company, and a prohibition on investing more than 5% of
a Fund's total assets in securities of any one investment company or more than
10% of its total assets in securities of all investment companies. A Fund will
indirectly bear its proportionate share of any management fees and other
expenses paid by such other investment companies. Such other investment compa-
nies will have investment objectives,

                                                                      APPENDIX A
 
policies and restrictions substantially similar to those of the acquiring Fund
and will be subject to substantially the same risks.
 
ILLIQUID SECURITIES. Each Fund may invest up to 10% of its net assets in illiq-
uid securities which cannot be disposed of in seven days in the ordinary course
of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
BORROWINGS. Each Fund may borrow up to 33 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
DOWNGRADED SECURITIES. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.
 
                                                                              49

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Funds. GSAM is referred to in this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Money Market Funds are managed to seek preservation of capital, daily
 liquidity and maximum current income. With each Fund, the Investment Adviser
 follows a conservative, risk-managed investment process that seeks to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 
 1.MANAGING CREDIT RISK
 
 The Investment Adviser's process for managing risk emphasizes:
 .INTENSIVE RESEARCH--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Funds. Sources for their
  analysis include third-party inputs, such as financial statements and media
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .TIMELY UPDATES--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 THE RESULT: AN "APPROVED" LIST OF HIGH-QUALITY CREDITS--The Investment
 Adviser's portfolio management team uses this approval list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
                                                                               1
<PAGE>
 
 
 
 2.MANAGING INTEREST RATE RISK
 
 Three main steps are followed in seeking to manage interest rate risk:
 .ESTABLISH WEIGHTED AVERAGE MATURITY (WAM) TARGET--WAM (the weighted average
  time until the yield of a portfolio reflects any changes in the current
  interest rate environment) is constantly revisited and adjusted as market
  conditions change. An overall strategy is developed by the portfolio
  management team based on insights gained from weekly meetings with both
  Goldman Sachs economists and economists from outside the firm.
 .IMPLEMENT OPTIMUM PORTFOLIO STRUCTURE--Proprietary models that seek the
  optimum balance of risk and return, in conjunction with the Investment
  Adviser's analysis of factors such as market events, short-term interest
  rates and each Fund's asset volatility, are used to identify the most
  effective portfolio structure.
 .CONDUCT RIGOROUS ANALYSIS OF NEW SECURITIES--The Investment Adviser's five-
  step process includes legal, credit, historical index and liquidity
  analysis, as well as price stress testing to determine suitability for
  money market mutual funds.
 
 3. MANAGING LIQUIDITY
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .Each Fund's clients and factors that influence their asset volatility;
 .Technical events that influence the trading range of federal funds and
  other short-term fixed-income markets; and
 .Bid-ask spreads associated with securities in the portfolios.
 
 Benchmarks for the Money Market Funds are the IBC FINANCIAL DATA UNIVERSAL
 AVERAGES. Each Fund tracks the IBC Index which best corresponds to the
 Fund's eligible investments.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 .THE FUNDS: Each Fund's securities are valued by the amortized cost method
  as permitted by Rule 2a-7 under the Investment Company Act of 1940, as
  amended (the "Act"). Under Rule 2a-7, each Fund may invest only in U.S.
  dollar-denominated securities that are determined to present minimal credit
  risk and meet certain other criteria, including conditions relating to
  maturity, diversification and credit quality. These operating policies may
  be more restrictive than the fundamental policies set forth in the State-
  ment of Additional Information (the "Additional Statement").
  .TAXABLE FUNDS: Prime Obligations, Money Market, Premium Money Market,
   Treasury Obligations and Government Funds.
  .TAX-ADVANTAGED FUNDS: Treasury Instruments and Federal Funds.
  .TAX-EXEMPT FUNDS: Tax-Free Money Market and Municipal Money Market Funds.
 .THE INVESTORS: The Funds are designed for institutional investors seeking a
  high rate of return, a stable net asset value ("NAV") and convenient liqui-
  dation privileges. The Funds are particularly suitable for banks, corpora-
  tions and other financial institutions that seek investment of short-term
  funds for their own accounts or for the accounts of their customers. Shares
  of the Government Fund are intended to qualify as eligible investments for
  federally chartered credit unions pursuant to Sections 107(7), 107(8) and
  107(15) of the Federal Credit Union Act, Part 703 of the National Credit
  Union Administration ("NCUA") Rules and Regulations and NCUA Letter Number
  155. The Fund intends to review changes in the applicable laws, rules and
  regulations governing eligible investments for federally chartered credit
  unions, and to take such action as may be necessary so that the investments
  of the Fund qualify as eligible investments under the Federal Credit Union
  Act and the regulations thereunder. Shares of the Government Fund, however,
  may or may not qualify as eligible investments for particular state-chart-
  ered credit unions. A state-chartered credit union should consult qualified
  legal counsel to determine whether the Government Fund is a permissible
  investment under the law applicable to it.
 .NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
 .MAXIMUM REMAINING MATURITY OF PORTFOLIO INVESTMENTS: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .DOLLAR-WEIGHTED AVERAGE PORTFOLIO MATURITY ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .INVESTMENT RESTRICTIONS: Each Fund is subject to certain investment
  restrictions that are described in detail under "Investment Restrictions"
  in the Additional
 
                                                                               3
<PAGE>
 
 
  Statement. Fundamental investment restrictions of a Fund cannot be changed
  without approval of a majority of the outstanding shares of that Fund. The
  Treasury Obligations Fund's policy of limiting its investments to U.S.
  Treasury Obligations (as defined in Appendix A) and related repurchase
  agreements is also fundamental. All investment objectives and policies not
  specifically designated as fundamental are non-fundamental and may be
  changed without shareholder approval.
 .DIVERSIFICATION: Diversification can help a Fund reduce the risks of
  investing. In accordance with current regulations of the Securities and
  Exchange Commission (the "SEC"), each Fund may not invest more than 5% of
  the value of its total assets at the time of purchase in the securities of
  any single issuer. However, a Fund may invest up to 25% of the value of the
  total assets in the securities of a single issuer for up to three business
  days. These limitations do not apply to cash, certain repurchase agree-
  ments, U.S. Government Securities (as defined in Appendix A) or securities
  of other investment companies. In addition, securities subject to certain
  unconditional guarantees and securities that are not "First Tier Securi-
  ties" as defined by the SEC are subject to different diversification
  requirements as described in the Additional Statement.

Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 The Prime Obligations, Money Market, Premium Money Market, Treasury Obliga-
 tions, Treasury Instruments, Government, Federal, Tax-Free Money Market and
 Municipal Money Market Funds seek to maximize current income to the extent
 consistent with the preservation of capital and the maintenance of liquidity
 by investing exclusively in high quality money market instruments.
 
 
 TAXABLE AND TAX-ADVANTAGED FUNDS:
 The Prime Obligations, Money Market and Premium Money Market Funds pursue
 their investment objectives by investing in U.S. Government Securities,
 obligations of U.S. banks, commercial paper and other short-term obligations
 of U.S. companies, states, municipalities and other entities and repurchase
 agreements. The Money Market and Premium Money Market Funds may also invest
 in U.S. dollar-denominated obligations of foreign banks, foreign companies
 and foreign governments. The Treasury Obligations Fund pursues its invest-
 ment objective by investing in securities issued by the U.S. Treasury and
 repurchase agreements relating to such securities. The Government Fund pur-
 sues its investment objective by investing in securities issued by the U.S.
 government, its agencies, authorities and instrumentalities and repurchase
 agreements relating to such securities. The Treasury Instruments and Federal
 Funds pursue their investment objectives by limiting their investments to
 certain U.S. Treasury Obligations and U.S. Government Securities, respec-
 tively, the interest from which is generally exempt from state income taxa-
 tion. You should consult your tax adviser to determine whether distributions
 from the Treasury Instruments and Federal Funds (and any other Fund that may
 hold such obligations) derived from interest on such obligations are exempt
 from state income taxation in your own state.
 
 In order to obtain a rating from a rating organization, the Prime Obliga-
 tions, Money Market, Premium Money Market, Treasury Obligations, Treasury
 Instruments, Government and Federal Funds will observe special investment
 restrictions.
 
 TAX-EXEMPT FUNDS:
 The Tax-Free Money Market and Municipal Money Market Funds pursue their
 investment objectives by investing in securities issued by or on behalf of
 states, territories, and possessions of the United States and their politi-
 cal subdivisions, agencies, authorities and instrumentalities, and the Dis-
 trict of Columbia, the interest from which, if any, is in the opinion of
 bond counsel excluded from gross income for federal income tax purposes, and
 with respect to the Tax-Free Money Market Fund, not an item of tax prefer-
 ence under the federal alternative minimum tax ("AMT"). With respect to the
 Municipal Money Market Fund, such interest may not necessarily be exempt
 from the AMT.
 
                                                                               5

 1 Issued or guaranteed by the U.S. Treasury.
 2 Including foreign branches of U.S. banks.
 3 If adverse economic conditions prevail in the banking industry (such as
   substantial losses on loans, increases in non-performing assets and charge-
   offs and declines in total deposits) the Funds may, for temporary defensive
   purposes, invest less than 25% of their total assets in bank obligations.
 4 Issued by the U.S. Treasury.
 5 To the extent required by Rule 2a-7, asset-backed and receivables-backed
   securities will be rated by the requisite number of nationally recognized
   statistical rating organizations ("NRSROs").
 6 The Funds may also invest in U.S. dollar-denominated obligations issued or
   guaranteed by any entity located or organized in a foreign country that
   maintains a short-term foreign currency rating in the highest short-term
   ratings category by the requisite number of NRSRO's. The Funds may not
   invest more than 25% of their total assets in the securities of any one
   foreign government.

 7 Will only make such investments when yields on such securities are
   attractive compared to other taxable investments.
 8 Ordinarily expect that 100% of a Fund's portfolio securities will be
   invested in municipal obligations, but the Funds may, for temporary
   defensive purposes, hold cash or invest in short-term taxable securities.
 9 To the extent permitted by Rule 2a-7, securities without short-term ratings
   may be purchased if they are deemed to be of comparable quality to First
   Tier Securities, or to the extent that a Fund may purchase Second Tier
   Securities, comparable in quality to Second Tier Securities. In addition, a
   Fund holding a security supported by a guarantee or demand feature may rely
   on the credit quality of the guarantee or demand feature in determining the
   credit quality of the investment.
 10 If such policy should change, private activity bonds subject to AMT would
    not exceed 20% of a Fund's net assets under normal market conditions.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

Risks that apply to all Funds:
 
 .NAV RISK--The risk that a Fund will not be able to maintain a NAV per share of
 $1.00 at all times.
 .INTEREST RATE RISK--The risk that during periods of rising interest rates, a
 Fund's yield (and the market value of its securities) will tend to be lower
 than prevailing market rates; in periods of falling interest rates, a Fund's
 yield will tend to be higher.
 .CREDIT/DEFAULT RISK--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Free Money Market and Municipal Money Market Funds, risk of loss from pay-
 ment default may also exist where municipal instruments which are backed by
 foreign letters of credit or guarantees.
 .LIQUIDITY RISK--The risk that a Fund will be unable to pay redemption proceeds
 within the time period stated in this Prospectus, because of unusual market
 conditions, an unusually high volume of redemption requests, or other reasons.
 .OTHER RISKS--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Risk that applies to the Prime Obligations, Money Market, Premium Money Market,
Government and Federal Funds:
 
 .U.S. GOVERNMENT SECURITIES RISK--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market and Premium Money Market Funds:
 
 .FOREIGN RISK--The risk that a foreign security could lose value as a result of
 political, financial and economic events in foreign countries, less publicly
 available financial and other information, less stringent foreign securities
 regulations and accounting and disclosure standards, or other factors. The
 Money Market and Premium Money Market Funds may not invest more than 25% of
 their total assets in the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
 .BANKING INDUSTRY RISK--The risk that if a Fund invests more than 25% of its
 total assets in bank obligations, an adverse development in the banking indus-
 try may affect the value of the Fund's investments more than if a Fund's
 investments were not invested to such a degree in the banking industry. Nor-
 mally, the Money Market and Premium Money Market Funds intend to invest more
 than 25% of their total assets in bank obligations. Banks may be particularly
 susceptible to certain economic factors such as interest rate changes, adverse
 developments in the real estate market, fiscal and monetary policy and general
 economic cycles.
 
Risks that apply to the Tax-Exempt Funds:
 
 .CONCENTRATION RISK--The risk that if a Fund invests more than 25% of its total
 assets in issuers within the same state, industry or economic sector, an
 adverse economic, business or political development may affect the value of
 the Fund's investments more than if its investments were not so concentrated.
 .TAX RISK--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of a Fund to pay federal tax-

niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Pre-
 ferred Shares from year to year; and (b) the average annual returns of a
 Fund's Preferred Shares. Investors should be aware that the fluctuation of
 interest rates is one primary factor in performance volatility. The bar
 chart and table assume reinvestment of dividends and distributions. A Fund's
 past performance is not necessarily an indication of how the Fund will per-
 form in the future. Performance reflects expense limitations in effect. If
 expense limitations were not in place, a Fund's performance would have been
 reduced. You may obtain a Fund's current yield by calling 1-800-621-2550. No
 information has been provided for the Municipal Money Market Fund because it
 has not yet commenced operations.

Fund Fees and Expenses continued
 
 
 /1/The Funds' annual operating expenses are based on actual expenses, except
 for the Municipal Money Market Fund which are based on estimated amounts for
 the current fiscal year.
 /2/The Investment Adviser has voluntarily agreed not to impose a portion of
 the management fee on the Funds equal to 0.035% of the Funds' average daily
 net assets. AS A RESULT OF FEE WAIVERS, THE CURRENT MANAGEMENT FEES OF THE
 FUNDS ARE 0.17% OF THE FUNDS' AVERAGE DAILY NET ASSETS. THE WAIVERS MAY BE
 TERMINATED AT ANY TIME AT THE OPTION OF THE INVESTMENT ADVISER.
 /3/Service Organizations may charge other fees directly to their customers
 who are beneficial owners of Preferred Shares in connection with their cus-
 tomers' accounts. Such fees may affect the return customers realize with
 respect to their investments.

 other extraordinary expenses) to 0.01% of each Fund's average daily net
 assets.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in Preferred
Shares of a Fund for the time periods indicated and then redeem all of your
shares at the end of those periods. The Example also assumes that your invest-
ment has a 5% return each year and that a Fund's operating expenses remain the
same. Although your actual costs may be higher or lower, based on these assump-
tions your costs would be:

Service Organizations that invest in Preferred Shares on behalf of their cus-
tomers may charge other fees directly to their customer accounts in connection
with their investments. You should contact your Service Organization for infor-
mation regarding such charges. Such fees, if any, may affect the return such
customers realize with respect to their investments.
 
Certain Service Organizations may receive other compensation in connection with
the sale and distribution of Preferred Shares or for services to their custom-
ers' accounts and/or the Funds. For additional information regarding such com-
pensation, see "Shareholder Guide" in the Prospectus and "Other Information" in

Service Providers
 
 INVESTMENT ADVISER
 
 
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. The Goldman Sachs Group,
 L.P., which controls the Investment Adviser, announced that it will pursue
 an initial public offering of the firm in the late spring or early summer of
 1999. Simultaneously with the offering, the Goldman Sachs Group, L.P. will
 merge into The Goldman Sachs Group, Inc. As of February 28, 1999, GSAM,
 together with its affiliates, acted as investment adviser or distributor for
 assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
 .Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
 .Administers each Fund's business affairs
 .Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)
 
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter
 into principal transactions in certain taxable money market instruments,
 including repurchase agreements, with Goldman Sachs.

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
                                                                              29

 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.

Dividends
 
 
Dividends will be distributed to shareholders monthly. You may choose to have
dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time. If you do not indicate any
choice, your dividends and distributions will be reinvested automatically in
the applicable Fund.
 
All or substantially all of each Fund's net investment income will be declared
as a dividend daily. Dividends will normally, but not always, be declared as of
the following times:

Dividends will be reinvested as of the last calendar day of each month. Cash
distributions normally will be paid on or about the first business day of each
month. Net short-term capital gains, if any, will be distributed in accordance
with federal income tax requirements and may be reflected in a Fund's daily
distributions.
 
Each Fund may distribute at least annually other realized capital gains, if
any, after reduction by available capital losses. In order to avoid excessive
fluctuations in the amount of monthly capital gains distributions, a portion of
any net capital gains realized on the disposition of securities during the
months of November and December may be distributed during the subsequent calen-
dar year. Although realized gains and
 
                                                                              31

losses on the assets of a Fund are reflected in the NAV of the Fund, they are
not expected to be of an amount which would affect the Fund's NAV of $1.00 per
share.
 
The income declared as a dividend for the Prime Obligations, Treasury Obliga-
tions, Government and Premium Money Market Funds is based on estimates of net
investment income for each Fund. Actual income may differ from estimates, and
differences, if any, will be included in the calculation of subsequent divi-
dends.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Preferred
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Preferred Shares Of The Funds?
 Generally, Preferred Shares may be purchased only through institutions that
 have agreed to provide account administration and maintenance services to
 their customers who are the beneficial owners of Preferred Shares. These
 institutions are called "Service Organizations." Customers of a Service
 Organization will normally give their purchase instructions to the Service
 Organization, and the Service Organization will, in turn, place purchase
 orders with Goldman Sachs. Service Organizations will set times by which
 purchase orders and payments must be received by them from their customers.
 Generally, Preferred Shares may be purchased from the Funds on any business
 day at their NAV next determined after receipt of an order by Goldman Sachs
 from a Service Organization. Shares begin earning dividends after the Fund's
 receipt of the purchase amount in federal funds. No sales load is charged.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place a purchase order in writing or by telephone.

</TABLE>
 Before or immediately after placing an initial purchase order, a Service
 Organization should complete and send to Goldman Sachs the Account Applica-
 tion attached to this Prospectus.
 
 Service Organizations may send their payments as follows:
 .Wire federal funds to The Northern Trust Company ("Northern"), as sub-
  custodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); OR
 
                                                                              33
<PAGE>
 
 
 .Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; OR
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds -
  (Name of Fund and Class of Shares), 4900 Sears Tower - 60th Floor, Chicago,
  IL 60606-6372. The Funds will not accept a check drawn on a foreign bank or
  a third-party check.
 
 IT IS STRONGLY RECOMMENDED THAT PAYMENT BE EFFECTED BY WIRING FEDERAL FUNDS
 TO NORTHERN.
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.

 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Preferred Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and may designate other interme-
 diaries to accept such orders, if approved by the Trust. In these cases:

 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to a preferred administration plan adopted by the Trust's Board of
 Trustees, Service Organizations are entitled to receive payment for their
 services from the Trust of up to 0.10% (on an annualized basis) of the aver-
 age daily net assets of the Preferred Shares of the Funds, which are attrib-
 utable to or held in the name of the Service Organization for its customers.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses.
 
 In addition to Preferred Shares, each Fund also offers other classes of
 shares to investors. These other share classes are subject to different fees
 and expenses (which affect performance), and are entitled to different serv-
 ices than Preferred Shares. Information regarding these other share classes
 may be obtained from your sales representative or from Goldman Sachs by
 calling the number on the back cover of this Prospectus.

<PAGE>
 
 
 A Service Organization may impose a minimum amount for initial and subse-
 quent investments in Preferred Shares and may establish other requirements
 such as a minimum account balance. A Service Organization may redeem Pre-
 ferred Shares held by non-complying accounts, and may impose a charge for
 any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment and minimum account balance require-
  ment.
 .Reject any purchase order for any reason.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Preferred Shares
 is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________

  open, except for days on which Chicago, Boston or New York banks are closed
  for local holidays.
 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-

 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Preferred Shares Of The Funds?
 Generally, Preferred Shares may be sold (redeemed) only through Service
 Organizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. GENERALLY,
 EACH FUND WILL REDEEM ITS PREFERRED SHARES UPON REQUEST ON ANY BUSINESS DAY
 AT THEIR NAV NEXT DETERMINED AFTER RECEIPT OF SUCH REQUEST IN PROPER FORM. A
 Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is elected on the Account
 Application.

 Certain Service Organizations are authorized to accept redemption requests
 on behalf of the Funds as described under "What Do I Need To Know About
 Service Organizations?" A redemption may also be made with respect to cer-
 tain Funds by means of the check redemption privilege described in the Addi-
 tional Statement.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 
                                                                              37
<PAGE>
 
 
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 NOTE: IT MAY BE DIFFICULT TO MAKE TELEPHONE REDEMPTIONS IN TIMES OF DRASTIC
 ECONOMIC OR MARKET CONDITIONS.
 
 When Will Redemption Proceeds Be Wired?
 Redemption proceeds will normally be wired to the bank account designated on
 a Service Organization's Account Application as follows:

  when your check has cleared, which may take up to 15 days. If the Federal
  Reserve Bank is closed on the day that the redemption proceeds would
  ordinarily be wired, wiring the redemption proceeds may be delayed one
  additional business day.
 .Neither the Trust nor Goldman Sachs assumes any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organizations.
 
 What Else Do I Need To Know About Redemptions?
 
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem the Preferred Shares of any Service Organization whose account bal-
  ance falls below the minimum as a result of a redemption. The Fund will
  give 60 days' prior written notice to allow a Service Organization to pur-
  chase sufficient additional shares of the Fund in order to avoid such
  redemption.
 .Redeem shares in other circumstances determined by the Board of Trustees to
  be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash)
  from the Fund. If you receive redemption proceeds in-kind, you should
  expect to incur transaction costs upon the disposition of those securities.

 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Preferred Shares of a Fund at NAV for
 shares of the corresponding class of any other Goldman Sachs Fund. The
 exchange privilege may be materially modified or withdrawn at any time upon
 60 days' written notice.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirement of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.

 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will I Be Sent Regarding Investments In Preferred
 Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Upon request, Service
 Organizations will also be provided with a printed confirmation for each
 transaction. Any dividends and distributions paid by the Funds are also
 reflected in regular statements issued by the Funds to Service Organiza-
 tions. Service Organizations are responsible for providing these or other
 reports to their customers who are the beneficial owners of Preferred Shares
 in accordance with the rules that apply to their accounts with the Service
 Organizations.

Taxation
 
 
Each Fund intends to qualify as a regulated investment company for federal tax
purposes, and to distribute to shareholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Funds, Fund dividends will generally be taxable to
you as ordinary income (unless your investment is in an IRA or other tax-
advantaged account) regardless of whether you reinvest in additional shares or
take them as cash. The Tax-Exempt Funds expect generally to distribute "exempt-
interest dividends," which will be tax-exempt income for federal income tax
purposes. The tax status and amounts of the dividends for each calendar year
will be detailed in your annual tax statement from the Funds.
 
Dividends and distributions from each Fund will generally be taxable to you in
the tax year in which they are paid, with one exception. Dividends and distri-
butions declared by a Fund in October, November or December and paid in January
are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry shares of the
Tax-Exempt Funds generally will not be deductible for federal income tax pur-
poses.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Funds may be an item of tax preference for purposes of determining
your AMT liability. Exempt-interest dividends will also be considered along
with other adjusted gross income in determining whether any social security or
railroad retirement payments received by you are subject to federal income tax-
es.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from any Fund (including the Tax-Exempt Funds)
or on the value of the shares held by you. More tax information is provided in
the Additional Statement. You should also consult your own tax adviser for
information regarding all tax consequences applicable to your investments in
the Funds.

Appendix A
Additional Information on Portfolio
Risks, Securities and Techniques
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Funds, including their associated
risks. Additional information is provided in the Additional Statement, which is
available upon request. Among other things, the Additional Statement describes
certain fundamental policies and investment restrictions that cannot be changed
without shareholder approval. You should note, however, that all policies not
specifically designated as fundamental are non-fundamental and may be changed
without shareholder approval. If there is a change in a Fund's investment
objective, you should consider whether that Fund remains an appropriate invest-
ment in light of your then current financial position and needs.
 
U.S. TREASURY OBLIGATIONS AND U.S. GOVERNMENT SECURITIES AND RELATED CUSTODIAL
RECEIPTS. U.S. Treasury Obligations include securities issued or issued or
guaranteed by the U.S. Treasury ("U.S. Treasury Obligations"). Payment of
principal and interest on these obligations is backed by the full faith and
credit of the U.S. government. U.S. Treasury Obligations include, among other
things, the separately traded principal and interest components of securities
guaranteed or issued by the U.S. Treasury if such components are traded
independently under the Separate Trading of Registered Interest and Principal
of Securities program ("STRIPS").
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury Obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.
 
                                                                              43

Some Funds invest in U.S. Treasury Obligations and certain U.S. Government
Securities the interest from which is generally exempt from state income taxa-
tion. Securities generally eligible for this exemption include those issued by
the U.S. Treasury and certain agencies, authorities or instrumentalities of the
U.S. government, including the Federal Home Loan Banks, Federal Farm Credit
Banks, Tennessee Valley Authority and Student Loan Marketing Association.
 
U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Certain Funds may also acquire U.S. Government Securities in the form of custo-
dial receipts. Custodial receipts evidence ownership of future interest pay-
ments, principal payments or both on notes or bonds issued or guaranteed as to
principal or interest by the U.S. government, its agencies, instrumentalities,
political subdivisions or authorities. For certain securities law purposes,
custodial receipts are not considered obligations of the U.S. government.
 
BANK OBLIGATIONS. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. Certain Funds may invest in obligations issued or
backed by U.S. banks when a bank has more than $1 billion in total assets at
the time of purchase or is a branch or subsidiary of such a bank. In addition,
certain Funds may invest in U.S. dollar-denominated obligations issued or
guaranteed by foreign banks that have more than $1 billion in total assets at
the time of purchase, U.S. branches of such foreign banks (Yankee obligations),
foreign branches of such foreign banks and foreign branches of U.S. banks
having more than $1 billion in total assets at the time of purchase. Bank
obligations may be general obligations of the parent bank or may be limited to
the issuing branch by the terms of the specific obligation or by government
regulation.
 
If a Fund invests more than 25% of its total assets in bank obligations
(whether foreign or domestic), it may be especially affected by favorable and
adverse developments in or related to the banking industry. The activities of
U.S. and most foreign banks are subject to comprehensive regulations which, in
the case of U.S. regulations, have undergone substantial changes in the past
decade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of opera-
tions and profitability of domestic and foreign banks. Significant developments
in the U.S. banking industry have included increased competition from other
types of financial institutions, increased acquisition activity and geographic
expansion. Banks may be particularly susceptible to certain economic factors,
such as interest rate changes and adverse developments in the real

                                                                      APPENDIX A
 
estate markets. Fiscal and monetary policy and general economic cycles can
affect the availability and cost of funds, loan demand and asset quality and
thereby impact the earnings and financial conditions of banks.
 
COMMERCIAL PAPER. A Fund may invest in commercial paper, including variable
amount master demand notes and asset-backed commercial paper. Commercial paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, finance companies and other issuers.
The commercial paper purchased by a Fund consists of direct U.S. dollar-denomi-
nated obligations of domestic or, in the case of certain Funds, foreign
issuers.
 
SHORT-TERM OBLIGATIONS. A Fund may invest in other short-term obligations,
including short-term funding agreements payable in U.S. dollars and issued or
guaranteed by U.S. corporations, foreign corporations or other entities. A
funding agreement is a contract between an issuer and a purchaser that obli-
gates the issuer to pay a guaranteed rate of interest on a principal sum depos-
ited by the purchaser. Funding agreements will also guarantee a stream of pay-
ments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and guaran-
teed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Fund will be regarded as
illiquid.
 
ASSET-BACKED AND RECEIVABLES-BACKED SECURITIES. Certain Funds may invest in
asset-backed and receivables-backed securities whose principal and interest
payments are collateralized by pools of assets such as auto loans, credit card
receivables, leases, installment contracts and personal property. Asset-backed
and receivables-backed securities are often subject to more rapid repayment
than their stated maturity date would indicate as a result of the pass-through
of prepayments of principal on the underlying loans. During periods of
declining interest rates, prepayment of loans underlying asset-backed and
receivables-backed securities can be expected to accelerate. Accordingly, a
Fund's ability to maintain positions in such securities will be affected by
reductions in the principal amount of such securities resulting from
prepayments, and its ability to reinvest the returns of principal at comparable
yields is subject to generally prevailing interest rates at that time. In
addition, securities that are backed by credit card, automobile and similar
types of receivables generally do not have the benefit of a security interest
in collateral that is comparable in quality to mortgage assets. There is the
possibility that, in some cases, recoveries on repossessed collateral may not
be available to support payments on these securities. In the event of a
default, a Fund may suffer a loss if it cannot sell collateral quickly and
receive the amount it is owed.
 
FOREIGN GOVERNMENT OBLIGATIONS AND RELATED FOREIGN RISKS. Certain Funds may
invest in foreign government obligations. Foreign government obligations are
U.S.
 
                                                                              45
<PAGE>
 
 
dollar-denominated obligations (limited to commercial paper and other notes)
issued or guaranteed by a foreign government or other entity located or
organized in a foreign country that maintains a short-term foreign currency
rating in the highest short-term ratings category by the requisite number of
NRSROs.
 
Investments by a Fund in foreign securities, whether issued by a foreign gov-
ernment, bank, corporation or other issuer, may present a greater degree of
risk than investments in securities of domestic issuers because of less public-
ly-available financial and other information, less securities regulation,
potential imposition of foreign withholding and other taxes, war, expropriation
or other adverse governmental actions. Efforts in foreign countries to remedi-
ate potential Year 2000 problems are not as extensive as those in the United
States. As a result, the operations of foreign markets, foreign issuers and
foreign governments may be disrupted by the Year 2000 Problem, and the invest-
ment portfolio of a Fund may be adversely affected. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and generally
are not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks.
 
REPURCHASE AGREEMENTS. Certain Funds may enter into repurchase agreements with
primary dealers in U.S. Government Securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund are less than the repurchase price and the Fund's
cost associated with delay and enforcement of the repurchase agreement. In
addition, in the event of bankruptcy of the seller, a Fund could suffer addi-
tional losses if a court determines that the Fund's interest in the collateral
is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, certain Funds, together with other registered
investment companies having advisory agreements with the Investment Adviser or
any of its affiliates, may transfer uninvested cash balances into a single
joint account, the daily aggregate balance of which will be invested in one or
more repurchase agreements.
 
MUNICIPAL OBLIGATIONS. Certain Funds may invest in municipal obligations.
Municipal obligations are issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies,
authorities and instrumentalities, and the District of Columbia. Municipal
obligations may include fixed rate notes and similar debt instruments; variable
and floating rate demand instruments; tax-exempt commercial paper; municipal
bonds; and unrated notes, paper, bonds or other instruments.

                                                                      APPENDIX A
 
 
MUNICIPAL NOTES AND BONDS. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
TENDER OPTION BONDS. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Fund's average portfolio maturity. There is a risk that a Fund will not be con-
sidered the owner of a tender option bond for federal income tax purposes, and
thus will not be entitled to treat such interest as exempt from federal
income tax. Certain tender option bonds may be illiquid or may become illiquid
as a result of a credit rating downgrade, a payment default or a disqualifica-
tion from tax-exempt status.
 
REVENUE ANTICIPATION WARRANTS. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which
 
                                                                              47
<PAGE>
 
 
include a demand feature that permits the holder to sell the RAWs to a bank or
other financial institution at a purchase price equal to par plus accrued
interest on each interest rate reset date.
 
INDUSTRIAL DEVELOPMENT BONDS. Certain Funds may invest in industrial develop-
ment bonds (private activity bonds). Industrial development bonds are a spe-
cific type of revenue bond backed by the credit and security of a private user,
the interest from which would be an item of tax preference when distributed by
a Fund as "exempt-interest dividends" to shareholders under the AMT.
 
OTHER MUNICIPAL OBLIGATION POLICIES. Certain Funds may invest 25% or more of
the value of their respective total assets in municipal obligations which are
related in such a way that an economic, business or political development or
change affecting one municipal obligation would also affect the other municipal
obligation. For example, a Fund may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of a Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political developments affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality of these banks and financial institutions could,
therefore, cause a loss to a Fund that invests in municipal obligations. Let-
ters of credit and other obligations of foreign banks and financial institu-
tions may involve risks in addition to those of domestic obligations because of
less publicly available financial and other information, less securities regu-
lation, potential imposition of foreign withholding and other taxes, war,
expropriation or other adverse governmental actions. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and are gener-
ally not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks. In addition, the Funds may acquire securities in the
form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.

FLOATING AND VARIABLE RATE OBLIGATIONS. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Fund may consider the maturity of a variable or floating rate obli-
gation to be shorter than its ultimate stated maturity if the obligation is a
U.S. Treasury Obligation or U.S. Government Security, if the obligation has a
remaining maturity of 397 calendar days or less, or if the obligation has a
demand feature that permits the Fund to receive payment at any time or at spec-
ified intervals not exceeding 397 calendar days. The issuers or financial
intermediaries providing demand features may support their ability to purchase
the obligations by obtaining credit with liquidity supports. These may include
lines of credit, which are conditional commitments to lend and letters of cred-
it, which will ordinarily be irrevocable, both of which may be issued by domes-
tic banks or foreign banks which have a branch, agency or subsidiary in the
United States. A Fund may purchase variable or floating rate obligations from
the issuers or may purchase certificates of participation, a type of floating
or variable rate obligation, which are interests in a pool of debt obligations
held by a bank or other financial institution.
 
WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS. The Funds may purchase when-
issued securities and make contract to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. When-issued securities
are securities that have been authorized, but not yet issued. When-issued secu-
rities are purchased in order to secure what is considered to be an advanta-
geous price and yield to a Fund at the time of entering into the transaction. A
forward commitment involves entering into a contract to purchase or sell secu-
rities for a fixed price at a future date beyond the customary settlement peri-
od.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Fund will generally purchase
securities on a when-issued or forward commitment basis with the intention of
acquiring securities for its portfolio, a Fund may dispose of when-issued secu-
rities or forward commitments prior to settlement if the Investment Adviser
deems it appropriate.
 
OTHER INVESTMENT COMPANIES. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Act. These limitations
include a prohibition on any Fund acquiring more than 3% of the voting shares
of any other investment company, and a prohibition on investing more than 5% of
a Fund's total assets in securities of any one investment company or more than
10% of its total assets in securities of all investment companies. A Fund will
indirectly bear its proportionate share of any management fees and other
expenses paid by such other investment companies. Such other investment compa-
nies will have investment objectives,
 
                                                                              49

policies and restrictions substantially similar to those of the acquiring Fund
and will be subject to substantially the same risks.
 
ILLIQUID SECURITIES. Each Fund may invest up to 10% of its net assets in illiq-
uid securities which cannot be disposed of in seven days in the ordinary course
of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
BORROWINGS. Each Fund may borrow up to 33 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
DOWNGRADED SECURITIES. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Funds. GSAM is referred to in this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Money Market Funds are managed to seek preservation of capital, daily
 liquidity and maximum current income. With each Fund, the Investment Adviser
 follows a conservative, risk-managed investment process that seeks to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 
 1.MANAGING CREDIT RISK
 
 The Investment Adviser's process for managing risk emphasizes:
 .INTENSIVE RESEARCH--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Funds. Sources for their
  analysis include third-party inputs, such as financial statements and media
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .TIMELY UPDATES--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 THE RESULT: AN "APPROVED" LIST OF HIGH-QUALITY CREDITS--The Investment
 Adviser's portfolio management team uses this approval list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
                                                                               1
<PAGE>
 
 
 
 2.MANAGING INTEREST RATE RISK
 
 Three main steps are followed in seeking to manage interest rate risk:
 .ESTABLISH WEIGHTED AVERAGE MATURITY (WAM) TARGET--WAM (the weighted average
  time until the yield of a portfolio reflects any changes in the current
  interest rate environment) is constantly revisited and adjusted as market
  conditions change. An overall strategy is developed by the portfolio
  management team based on insights gained from weekly meetings with both
  Goldman Sachs economists and economists from outside the firm.
 .IMPLEMENT OPTIMUM PORTFOLIO STRUCTURE--Proprietary models that seek the
  optimum balance of risk and return, in conjunction with the Investment
  Adviser's analysis of factors such as market events, short-term interest
  rates and each Fund's asset volatility, are used to identify the most
  effective portfolio structure.
 .CONDUCT RIGOROUS ANALYSIS OF NEW SECURITIES--The Investment Adviser's five-
  step process includes legal, credit, historical index and liquidity
  analysis, as well as price stress testing to determine suitability for
  money market mutual funds.
 
 3. MANAGING LIQUIDITY
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .Each Fund's clients and factors that influence their asset volatility;
 .Technical events that influence the trading range of federal funds and
  other short-term fixed-income markets; and
 .Bid-ask spreads associated with securities in the portfolios.
 
 Benchmarks for the Money Market Funds are the IBC FINANCIAL DATA UNIVERSAL
 AVERAGES. Each Fund tracks the IBC Index which best corresponds to the
 Fund's eligible investments.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 .THE FUNDS: Each Fund's securities are valued by the amortized cost method
  as permitted by Rule 2a-7 under the Investment Company Act of 1940, as
  amended (the "Act"). Under Rule 2a-7, each Fund may invest only in U.S.
  dollar-denominated securities that are determined to present minimal credit
  risk and meet certain other criteria, including conditions relating to
  maturity, diversification and credit quality. These operating policies may
  be more restrictive than the fundamental policies set forth in the State-
  ment of Additional Information (the "Additional Statement").
  .TAXABLE FUNDS: Prime Obligations, Money Market, Premium Money Market,
   Treasury Obligations and Government Funds.
  .TAX-ADVANTAGED FUNDS: Treasury Instruments and Federal Funds.
  .TAX-EXEMPT FUNDS: Tax-Free Money Market and Municipal Money Market Funds.
 .THE INVESTORS: The Funds are designed for institutional investors seeking a
  high rate of return, a stable net asset value ("NAV") and convenient liqui-
  dation privileges. The Funds are particularly suitable for banks, corpora-
  tions and other financial institutions that seek investment of short-term
  funds for their own accounts or for the accounts of their customers. Shares
  of the Government Fund are intended to qualify as eligible investments for
  federally chartered credit unions pursuant to Sections 107(7), 107(8) and
  107(15) of the Federal Credit Union Act, Part 703 of the National Credit
  Union Administration ("NCUA") Rules and Regulations and NCUA Letter Number
  155. The Fund intends to review changes in the applicable laws, rules and
  regulations governing eligible investments for federally chartered credit
  unions, and to take such action as may be necessary so that the investments
  of the Fund qualify as eligible investments under the Federal Credit Union
  Act and the regulations thereunder. Shares of the Government Fund, however,
  may or may not qualify as eligible investments for particular state-chart-
  ered credit unions. A state-chartered credit union should consult qualified
  legal counsel to determine whether the Government Fund is a permissible
  investment under the law applicable to it.
 .NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
 .MAXIMUM REMAINING MATURITY OF PORTFOLIO INVESTMENTS: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .DOLLAR-WEIGHTED AVERAGE PORTFOLIO MATURITY ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .INVESTMENT RESTRICTIONS: Each Fund is subject to certain investment
  restrictions that are described in detail under "Investment Restrictions"
  in the Additional
 
                                                                               3
<PAGE>
 
 
  Statement. Fundamental investment restrictions of a Fund cannot be changed
  without approval of a majority of the outstanding shares of that Fund. The
  Treasury Obligations Fund's policy of limiting its investments to U.S.
  Treasury Obligations (as defined in Appendix A) and related repurchase
  agreements is also fundamental. All investment objectives and policies not
  specifically designated as fundamental are non-fundamental and may be
  changed without shareholder approval.
 .DIVERSIFICATION: Diversification can help a Fund reduce the risks of
  investing. In accordance with current regulations of the Securities and
  Exchange Commission (the "SEC"), each Fund may not invest more than 5% of
  the value of its total assets at the time of purchase in the securities of
  any single issuer. However, a Fund may invest up to 25% of the value of the
  total assets in the securities of a single issuer for up to three business
  days. These limitations do not apply to cash, certain repurchase agree-
  ments, U.S. Government Securities (as defined in Appendix A) or securities
  of other investment companies. In addition, securities subject to certain
  unconditional guarantees and securities that are not "First Tier Securi-
  ties" as defined by the SEC are subject to different diversification
  requirements as described in the Additional Statement.

Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 The Prime Obligations, Money Market, Premium Money Market, Treasury Obliga-
 tions, Treasury Instruments, Government, Federal, Tax-Free Money Market and
 Municipal Money Market Funds seek to maximize current income to the extent
 consistent with the preservation of capital and the maintenance of liquidity
 by investing exclusively in high quality money market instruments.
 
 TAXABLE AND TAX-ADVANTAGED FUNDS:
 The Prime Obligations, Money Market and Premium Money Market Funds pursue
 their investment objectives by investing in U.S. Government Securities,
 obligations of U.S. banks, commercial paper and other short-term obligations
 of U.S. companies, states, municipalities and other entities and repurchase
 agreements. The Money Market and Premium Money Market Funds may also invest
 in U.S. dollar denominated obligations of foreign banks, foreign companies
 and foreign governments. The Treasury Obligations Fund pursues its invest-
 ment objective by investing in securities issued by the U.S. Treasury and
 repurchase agreements relating to such securities. The Government Fund pur-
 sues its investment objective by investing in securities issued by the U.S.
 Government, its agencies, authorities and instrumentalities and repurchase
 agreements relating to such securities. The Treasury Instruments and Federal
 Funds pursue their investment objectives by limiting their investments to
 certain U.S. Treasury Obligations and U.S. Government Securities, respec-
 tively, the interest from which is generally exempt from state income taxa-
 tion. You should consult your tax adviser to determine whether distributions
 from the Treasury Instruments and Federal Funds (and any other Fund that may
 hold such obligations) derived from interest on such obligations are exempt
 from state income taxation in your own state.
 
 In order to obtain a rating from a rating organization, the Prime Obliga-
 tions, Money Market, Premium Money Market, Treasury Obligations, Treasury
 Instruments, Government and Federal Funds will observe special investment
 restrictions.
 
 TAX-EXEMPT FUNDS:
 The Tax-Free Money Market and Municipal Money Market Funds pursue their
 investment objectives by investing in securities issued by or on behalf of
 states, territories, and possessions of the United States and their politi-
 cal subdivisions, agencies, authorities and instrumentalities, and the Dis-
 trict of Columbia, the interest from which, if any, is in the opinion of
 bond counsel excluded from gross income for federal income tax purposes, and
 with respect to the Tax-Free Money Market Fund, not an item of tax prefer-
 ence under the federal alternative minimum tax ("AMT"). With respect to the

 2 Including foreign branches of U.S. banks.
 3 If adverse economic conditions prevail in the banking industry (such as
   substantial losses on loans, increases in non-performing assets and charge-
   offs and declines in total deposits) the Funds may, for temporary defensive
   purposes, invest less than 25% of their total assets in bank obligations.
 4 Issued by the U.S. Treasury.
 5 To the extent required by Rule 2a-7, asset-backed and receivables-backed
   securities will be rated by the requisite number of nationally recognized
   statistical rating organizations ("NRSROs").
 6 The Funds may invest in U.S. dollar-denominated obligations (limited to
   commercial paper and other notes) issued or guaranteed by a foreign
   government. The Funds may also invest in U.S. dollar-denominated
   obligations issued or guaranteed by any entity located or organized in a
   foreign country that maintains a short-term foreign currency rating in the
   highest short-term ratings category by the requisite number of NRSRO's. The
   Funds may not invest more than 25% of their total assets in the securities
   of any one foreign government.

  7 Will only make such investments when yields on such securities are
    attractive compared to other taxable investments.
  8 Ordinarily expect that 100% of a Fund's portfolio securities will be
    invested in municipal obligations, but the Funds may, for temporary
    defensive purposes, hold cash or invest in short-term taxable securities.
  9 To the extent permitted by Rule 2a-7, securities without short-term
    ratings may be purchased if they are deemed to be of comparable quality to
    First Tier Securities, or to the extent that a Fund may purchase Second
    Tier Securities, comparable in quality to Second Tier Securities. In
    addition, a Fund holding a security supported by a guarantee or demand
    feature may rely on the credit quality of the guarantee or demand feature
    in determining the credit quality of the investment.
 10 If such policy should change, private activity bonds subject to AMT would
    not exceed 20% of a Fund's net assets under normal market conditions.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

Risks that apply to all Funds:
 
 .NAV RISK--The risk that a Fund will not be able to maintain a NAV per share of
 $1.00 at all times.
 .INTEREST RATE RISK--The risk that during periods of rising interest rates, a
 Fund's yield (and the market value of its securities) will tend to be lower
 than prevailing market rates; in periods of falling interest rates, a Fund's
 yield will tend to be higher.
 .CREDIT/DEFAULT RISK--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Free Money Market and Municipal Money Market Funds, risk of loss from pay-
 ment default may also exist where municipal instruments are backed by foreign
 letters of credit or guarantees.
 .LIQUIDITY RISK--The risk that a Fund will be unable to pay redemption proceeds
 within the time period stated in this Prospectus, because of unusual market
 conditions, an unusually high volume of redemption requests, or other reasons.
 .OTHER RISKS--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Risk that applies to the Prime Obligations, Money Market, Premium Money Market,
Government and Federal Funds:
 
 .U.S. GOVERNMENT SECURITIES RISK--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market and Premium Money Market Funds:
 
 .FOREIGN RISK--The risk that a foreign security could lose value as a result of
 political, financial and economic events in foreign countries, less publicly
 available financial and other information, less stringent foreign securities
 regulations and accounting and disclosure standards, or other factors. The
 Money Market and Premium Money Market Funds may not invest more than 25% of
 their total assets in the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
 .BANKING INDUSTRY RISK--The risk that if a Fund invests more than 25% of its
 total assets in bank obligations, an adverse development in the banking indus-
 try may affect the value of the Fund's investments more than if a Fund's
 investments were not invested to such a degree in the banking industry. Nor-
 mally, the Money Market and Premium Money Market Funds intend to invest more
 than 25% of their total assets in bank obligations. Banks may be particularly
 susceptible to certain economic factors such as interest rate changes, adverse
 developments in the real estate market, fiscal and monetary policy and general
 economic cycles.
 
Risks that apply to the Tax-Exempt Funds:
 
 .CONCENTRATION RISK--The risk that if a Fund invests more than 25% of its total
 assets in issuers within the same state, industry or economic sector, an
 adverse economic, business or political development may affect the value of
 the Fund's investments more than if its investments were not so concentrated.
 .TAX RISK--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of a Fund to pay federal tax-
 exempt dividends.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Admin-
 istration Shares from year to year; and (b) the average annual returns of a
 Fund's Administration Shares. Investors should be aware that the fluctuation
 of interest rates is one primary factor in performance volatility. The bar
 chart and table assume reinvestment of dividends and distributions. A Fund's
 past performance is not necessarily an indication of how the Fund will per-
 form in the future. Performance reflects expense limitations in effect. If
 expense limitations were not in place, a Fund's performance would have been
 reduced. You may obtain a Fund's current yield by calling 1-800-621-2550. No
 information has been provided for the Municipal Money Market Fund because it
 has not yet commenced operations.

Fund Fees and Expenses (continued)
 
/1/The Funds' annual operating expenses are based on actual expenses, except
for the Municipal Money Market Fund, which are based on estimated amounts for
the current fiscal year.
/2/The Investment Adviser has voluntarily agreed not to impose a portion of the
management fee on the Funds equal to 0.035% of the Funds' average daily net
assets. AS A RESULT OF FEE WAIVERS, THE CURRENT MANAGEMENT FEES OF THE FUNDS
ARE 0.17% OF THE FUNDS' AVERAGE DAILY NET ASSETS. THE WAIVERS MAY BE TERMINATED
AT ANY TIME AT THE OPTION OF THE INVESTMENT ADVISER.
/3/Service Organizations may charge other fees directly to their customers who
are beneficial owners of Administration Shares in connection with their custom-
ers' accounts. Such fees may affect the return customers realize with respect
to their investments.
/4/The Investment Adviser has voluntarily agreed to reduce or limit "Other
Expenses" of each Fund (excluding management fees, administration fees, taxes,
interest, brokerage fees and litigation, indemnification and other extraordi-
nary expenses) to 0.01% of each Fund's average daily net assets.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in Adminis-
tration Shares of a Fund for the time periods indicated and then redeem all of
your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that a Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

Service Organizations may charge other fees directly to their customer accounts

Certain Service Organizations may receive other compensation in connection with
the sale and distribution of Administration Shares or for services to their
customers' accounts and/or the Funds. For additional information regarding such

Service Providers
 
 INVESTMENT ADVISER
 
 
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. The Goldman Sachs Group,
 L.P., which controls the Investment Adviser announced that it will pursue an
 initial public offering of the firm in the late spring or early summer of
 1999. Simultaneously with the offering, the Goldman Sachs Group, L.P. will
 merge into The Goldman Sachs Group, Inc. As of February 28, 1999, GSAM,
 together with its affiliates, acted as investment adviser or distributor for
 assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
 .Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
 .Administers each Fund's business affairs
 .Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)
 
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter
 into principal transactions in certain taxable money market instruments,
 including repurchase agreements, with Goldman Sachs.

  operations.
 
 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
                                                                              29

 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.

Dividends will be reinvested as of the last calendar day of each month. Cash
distributions normally will be paid on or about the first business day of each
month. Net short-term capital gains, if any, will be distributed in accordance
with federal income tax requirements and may be reflected in a Fund's daily
distributions.
 
Each Fund may distribute at least annually other realized capital gains, if
any, after reduction by available capital losses. In order to avoid excessive
fluctuations in the amount of monthly capital gains distributions, a portion of
any net capital gains realized on the disposition of securities during the
months of November and December may be distributed during the subsequent calen-
dar year. Although realized gains and
 
                                                                              31

losses on the assets of a Fund are reflected in the NAV of the Fund, they are
not expected to be of an amount which would affect the Fund's NAV of $1.00 per
share.
 
The income declared as a dividend for the Prime Obligations, Treasury Obliga-
tions, Government and Premium Money Market Funds is based on estimates of net
investment income for each Fund. Actual income may differ from estimates, and
differences, if any, will be included in the calculation of subsequent divi-
dends.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Administration
 Shares.
 
 HOW TO BUY SHARES
 
 How Can I Purchase Administration Shares Of The Funds?
 Generally, Administration Shares may be purchased only through institutions
 that have agreed to provide account administration and maintenance services
 to their customers who are the beneficial owners of Administration Shares.
 These institutions are called "Service Organizations." Customers of a Serv-
 ice Organization will normally give their purchase instructions to the Serv-
 ice Organization, and the Service Organization will, in turn, place purchase
 orders with Goldman Sachs. Service Organizations will set times by which
 purchase orders and payments must be received by them from their customers.
 Generally, Administration Shares may be purchased from the Funds on any
 business day at their NAV next determined after receipt of an order by
 Goldman Sachs from a Service Organization. Shares begin earning dividends
 after the Fund's receipt of the purchase amount in federal funds. No sales
 load is charged.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place a purchase order in writing or by telephone.

 Before or immediately after placing an initial purchase order, a Service
 Organization should complete and send to Goldman Sachs the Account Applica-
 tion attached to this Prospectus.
 
 Service Organizations may send their payments as follows:
 .Wire federal funds to The Northern Trust Company ("Northern"), as sub-
  custodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); OR
 
                                                                              33
<PAGE>
 
 .Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; OR
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds -
  (Name of Fund and Class of Shares), 4900 Sears Tower-60th Floor, Chicago,
  IL 60606-6372. The Funds will not accept a check drawn on a foreign bank or
  a third-party check.
 
 IT IS STRONGLY RECOMMENDED THAT PAYMENT BE EFFECTED BY WIRING FEDERAL FUNDS
 TO NORTHERN.
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.

 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Administration Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on

 behalf of their customers, and may designate other intermediaries to accept
 such orders, if approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to an administration plan adopted by the Trust's Board of Trustees,
 Service Organizations are entitled to receive payment for their services
 from the Trust of up to 0.25% (on an annualized basis) of the average daily
 net assets of the Administration Shares of the Funds, which are attributable
 to or held in the name of the Service Organization for its customers.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses.
 
 In addition to Administration Shares, each Fund also offers other classes of
 shares to investors. These other share classes are subject to different fees
 and expenses (which affect performance), and are entitled to different serv-
 ices than Administration Shares. Information regarding these other share
 classes may be obtained from your sales representative or from Goldman Sachs
 by calling the number on the back cover of this Prospectus.

 A Service Organization may impose a minimum amount for initial and subse-
 quent investments in Administration Shares and may establish other require-
 ments such as a minimum account balance. A Service Organization may redeem
 Administration Shares held by non-complying accounts, and may impose a
 charge for any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment and minimum account balance require-
  ment.
 .Reject any purchase order for any reason.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Administration
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV =

  except for days on which Chicago, Boston or New York banks are closed for
  local holidays.
 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Administration Shares Of The Funds?
 Generally, Administration Shares may be sold (redeemed) only through Service
 Organizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. GENERALLY,
 EACH FUND WILL REDEEM ITS ADMINISTRATION SHARES UPON REQUEST ON ANY BUSINESS
 DAY AT THEIR NAV NEXT DETERMINED AFTER RECEIPT OF SUCH REQUEST IN PROPER
 FORM. A Service Organization may request redemptions in writing or by tele-
 phone if the optional telephone redemption privilege is elected on the
 Account Application.

 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 NOTE: IT MAY BE DIFFICULT TO MAKE TELEPHONE REDEMPTIONS IN TIMES OF DRASTIC
 ECONOMIC OR MARKET CONDITIONS.

 .Although redemption proceeds will normally be wired as described above,
  each Fund reserves the right to pay redemption proceeds up to three busi-
  ness days following receipt of a properly executed wire transfer redemption
  request. If you are selling shares you recently paid for by check, the Fund
  will pay you when your check has cleared, which may take up to 15 days. If
  the Federal Reserve Bank is closed on the day that the redemption proceeds
  would ordinarily be wired, wiring the redemption proceeds may be delayed
  one additional business day.
 .Neither the Trust nor Goldman Sachs assumes any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organizations.
 
                                                                              39
<PAGE>
 
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem the Administration Shares of any Service Organization whose account
  balance falls below the minimum as a result of a redemption. The Fund will
  give 60 days' prior written notice to allow a Service Organization to pur-
  chase sufficient additional shares of the Fund in order to avoid such
  redemption.
 .Redeem shares in other circumstances determined by the Board of Trustees to
  be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash)
  from the Fund. If you receive redemption proceeds in-kind, you should
  expect to incur transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 
 A Service Organization may exchange Administration Shares of a Fund at NAV
 for shares of the corresponding class of any other Goldman Sachs Fund. The
 exchange privilege may be materially modified or withdrawn at any time upon
 60 days' written notice.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will I Be Sent Regarding Investments In Administration
 Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Upon request, Service
 Organizations will also be provided with a printed confirmation for each
 transaction. Any dividends and distributions paid by the Funds are also
 reflected in regular statements issued by the Funds to Service Organiza-
 tions. Service Organizations are responsible for providing these or other
 reports to their customers who are the beneficial owners of Administration
 Shares in accordance with the rules that apply to their accounts with the
 Service Organizations.
 
                                                                              41
<PAGE>
 
Taxation
 
 
Each Fund intends to qualify as a regulated investment company for federal tax
purposes, and to distribute to shareholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Funds, Fund dividends will generally be taxable to
you as ordinary income (unless your investment is in an IRA or other tax-
advantaged account) regardless of whether you reinvest in additional shares or
take them as cash. The Tax-Exempt Funds expect generally to distribute "exempt-
interest dividends," which will be tax-exempt income for federal income tax
purposes. The tax status and amounts of the dividends for each calendar year
will be detailed in your annual tax statement from the Funds.
 
Dividends and distributions from each Fund will generally be taxable to you in
the tax year in which they are paid, with one exception. Dividends and distri-
butions declared by a Fund in October, November or December and paid in January
are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry shares of the
Tax-Exempt Funds generally will not be deductible for federal income tax pur-
poses.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Funds may be an item of tax preference for purposes of determining
your AMT liability. Exempt-interest dividends will also be considered along
with other adjusted gross income in determining whether any social security or
railroad retirement payments received by you are subject to federal income tax-
es.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from any Fund (including the Tax-Exempt Funds)
or on the value of the shares held by you. More tax information is provided in
the Additional Statement. You should also consult your own tax adviser for
information regarding all tax consequences applicable to your investments in
the Funds.

Appendix A
Additional Information on Portfolio
Risks, Securities and Techniques
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Funds, including their associated
risks. Additional information is provided in the Additional Statement, which is
available upon request. Among other things, the Additional Statement describes
certain fundamental policies and investment restrictions that cannot be changed
without shareholder approval. You should note, however, that all policies not
specifically designated as fundamental are non-fundamental and may be changed
without shareholder approval. If there is a change in a Fund's investment
objective, you should consider whether that Fund remains an appropriate invest-
ment in light of your then current financial position and needs.
 
U.S. TREASURY OBLIGATIONS AND U.S. GOVERNMENT SECURITIES AND RELATED CUSTODIAL
RECEIPTS. U.S. Treasury Obligations include securities issued or issued or
guaranteed by the U.S. Treasury ("U.S. Treasury Obligations"). Payment of
principal and interest on these obligations is backed by the full faith and
credit of the U.S. government. U.S. Treasury Obligations include, among other
things, the separately traded principal and interest components of securities
guaranteed or issued by the U.S. Treasury if such components are traded
independently under the Separate Trading of Registered Interest and Principal
of Securities program ("STRIPS").
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury Obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.

Some Funds invest in U.S. Treasury Obligations and certain U.S. Government
Securities the interest from which is generally exempt from state income taxa-
tion. Securities generally eligible for this exemption include those issued by
the U.S. Treasury and certain agencies, authorities or instrumentalities of the
U.S. government, including the Federal Home Loan Banks, Federal Farm Credit
Banks, Tennessee Valley Authority and Student Loan Marketing Association.
 
U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Certain Funds may also acquire U.S. Government Securities in the form of custo-
dial receipts. Custodial receipts evidence ownership of future interest pay-
ments, principal payments or both on notes or bonds issued or guaranteed as to
principal or interest by the U.S. government, its agencies, instrumentalities,
political subdivisions or authorities. For certain securities law purposes,
custodial receipts are not considered obligations of the U.S. government.
 
BANK OBLIGATIONS. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. Certain Funds may invest in obligations issued or
backed by U.S. banks when a bank has more than $1 billion in total assets at
the time of purchase or is a branch or subsidiary of such a bank. In addition,
certain Funds may invest in U.S. dollar-denominated obligations issued or
guaranteed by foreign banks that have more than $1 billion in total assets at
the time of purchase, U.S. branches of such foreign banks (Yankee obligations),
foreign branches of such foreign banks and foreign branches of U.S. banks
having more than $1 billion in total assets at the time of purchase. Bank
obligations may be general obligations of the parent bank or may be limited to
the issuing branch by the terms of the specific obligation or by government
regulation.
 
If a Fund invests more than 25% of its total assets in bank obligations
(whether foreign or domestic), it may be especially affected by favorable and
adverse developments in or related to the banking industry. The activities of
U.S. and most foreign banks are subject to comprehensive regulations which, in
the case of U.S. regulations, have undergone substantial changes in the past
decade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of opera-
tions and profitability of domestic and foreign banks. Significant developments
in the U.S. banking industry have included increased competition from other
types of financial institutions, increased acquisition activity and geographic
expansion. Banks may be particularly susceptible to certain economic factors,
such as interest rate changes and adverse developments in the real

                                                                      APPENDIX A
 
estate markets. Fiscal and monetary policy and general economic cycles can
affect the availability and cost of funds, loan demand and asset quality and
thereby impact the earnings and financial conditions of banks.
 
COMMERCIAL PAPER. A Fund may invest in commercial paper, including variable
amount master demand notes and asset-backed commercial paper. Commercial paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, finance companies and other issuers.
The commercial paper purchased by a Fund consists of direct U.S. dollar-denomi-
nated obligations of domestic or, in the case of certain Funds, foreign
issuers.
 
SHORT-TERM OBLIGATIONS. A Fund may invest in other short-term obligations,
including short-term funding agreements payable in U.S. dollars and issued or
guaranteed by U.S. corporations, foreign corporations or other entities. A
funding agreement is a contract between an issuer and a purchaser that obli-
gates the issuer to pay a guaranteed rate of interest on a principal sum depos-
ited by the purchaser. Funding agreements will also guarantee a stream of pay-
ments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and guaran-
teed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Fund will be regarded as
illiquid.
 
ASSET-BACKED AND RECEIVABLES-BACKED SECURITIES. Certain Funds may invest in
asset-backed and receivables-backed securities whose principal and interest
payments are collateralized by pools of assets such as auto loans, credit card
receivables, leases, installment contracts and personal property. Asset-backed
and receivables-backed securities are often subject to more rapid repayment
than their stated maturity date would indicate as a result of the pass-through
of prepayments of principal on the underlying loans. During periods of
declining interest rates, prepayment of loans underlying asset-backed and
receivables-backed securities can be expected to accelerate. Accordingly, a
Fund's ability to maintain positions in such securities will be affected by
reductions in the principal amount of such securities resulting from
prepayments, and its ability to reinvest the returns of principal at comparable
yields is subject to generally prevailing interest rates at that time. In
addition, securities that are backed by credit card, automobile and similar
types of receivables generally do not have the benefit of a security interest
in collateral that is comparable in quality to mortgage assets. There is the
possibility that, in some cases, recoveries on repossessed collateral may not
be available to support payments on these securities. In the event of a
default, a Fund may suffer a loss if it cannot sell collateral quickly and
receive the amount it is owed.
 
FOREIGN GOVERNMENT OBLIGATIONS AND RELATED FOREIGN RISKS. Certain Funds may
invest in foreign government obligations. Foreign government obligations are
U.S.
 
                                                                              45
<PAGE>
 
 
dollar-denominated obligations (limited to commercial paper and other notes)
issued or guaranteed by a foreign government or other entity located or
organized in a foreign country that maintains a short-term foreign currency
rating in the highest short-term ratings category by the requisite number of
NRSROs.
 
Investments by a Fund in foreign securities, whether issued by a foreign gov-
ernment, bank, corporation or other issuer, may present a greater degree of
risk than investments in securities of domestic issuers because of less public-
ly-available financial and other information, less securities regulation,
potential imposition of foreign withholding and other taxes, war, expropriation
or other adverse governmental actions. Efforts in foreign countries to remedi-
ate potential Year 2000 problems are not as extensive as those in the United
States. As a result, the operations of foreign markets, foreign issuers and
foreign governments may be disrupted by the Year 2000 Problem, and the invest-
ment portfolio of a Fund may be adversely affected. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and generally
are not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks.
 
REPURCHASE AGREEMENTS. Certain Funds may enter into repurchase agreements with
primary dealers in U.S. Government Securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund are less than the repurchase price and the Fund's
cost associated with delay and enforcement of the repurchase agreement. In
addition, in the event of bankruptcy of the seller, a Fund could suffer addi-
tional losses if a court determines that the Fund's interest in the collateral
is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, certain Funds, together with other registered
investment companies having advisory agreements with the Investment Adviser or
any of its affiliates, may transfer uninvested cash balances into a single
joint account, the daily aggregate balance of which will be invested in one or
more repurchase agreements.
 
MUNICIPAL OBLIGATIONS. Certain Funds may invest in Municipal obligations.
Municipal obligations are issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies,
authorities and instrumentalities, and the District of Columbia. Municipal
obligations may include fixed rate notes and similar debt instruments; variable
and floating rate demand

                                                                      APPENDIX A
 
instruments; tax-exempt commercial paper; municipal bonds; and unrated notes,
paper, bonds or other instruments.
 
MUNICIPAL NOTES AND BONDS. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
TENDER OPTION BONDS. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Fund's average portfolio maturity. There is a risk that a Fund will not be con-
sidered the owner of a tender option bond for federal income tax purposes, and
thus will not be entitled to treat such interest as exempt from federal
income tax. Certain tender option bonds may be illiquid or may become illiquid
as a result of a credit rating downgrade, a payment default or a disqualifica-
tion from tax-exempt status.
 
REVENUE ANTICIPATION WARRANTS. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such
 
                                                                              47
<PAGE>
 
 
revenues will be insufficient to satisfy the issuer's payment obligations. The
entire amount of principal and interest on RAWs is due at maturity. RAWs,
including those with a maturity of more than 397 days, may also be repackaged
as instruments which include a demand feature that permits the holder to sell
the RAWs to a bank or other financial institution at a purchase price equal to
par plus accrued interest on each interest rate reset date.
 
INDUSTRIAL DEVELOPMENT BONDS. Certain Funds may invest in industrial develop-
ment bonds (private activity bonds). Industrial development bonds are a spe-
cific type of revenue bond backed by the credit and security of a private user,
the interest from which would be an item of tax preference when distributed by
a Fund as "exempt-interest dividends" to shareholders under the AMT.
 
OTHER MUNICIPAL OBLIGATION POLICIES. Certain Funds may invest 25% or more of
the value of their respective total assets in municipal obligations which are
related in such a way that an economic, business or political development or
change affecting one municipal obligation would also affect the other municipal
obligation. For example, a Fund may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of a Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political developments affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality of these banks and financial institutions could,
therefore, cause a loss to a Fund that invests in municipal obligations. Let-
ters of credit and other obligations of foreign banks and financial institu-
tions may involve risks in addition to those of domestic obligations because of
less publicly available financial and other information, less securities regu-
lation, potential imposition of foreign withholding and other taxes, war,
expropriation or other adverse governmental actions. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and are gener-
ally not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks. In addition, the Funds may acquire securities in the
form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.

In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.
 
FLOATING AND VARIABLE RATE OBLIGATIONS. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Fund may consider the maturity of a variable or floating rate obli-
gation to be shorter than its ultimate stated maturity if the obligation is a
U.S. Treasury Obligation or U.S. Government Security, if the obligation has a
remaining maturity of 397 calendar days or less, or if the obligation has a
demand feature that permits the Fund to receive payment at any time or at spec-
ified intervals not exceeding 397 calendar days. The issuers or financial
intermediaries providing demand features may support their ability to purchase
the obligations by obtaining credit with liquidity supports. These may include
lines of credit, which are conditional commitments to lend and letters of cred-
it, which will ordinarily be irrevocable, both of which may be issued by domes-
tic banks or foreign banks which have a branch, agency or subsidiary in the
United States. A Fund may purchase variable or floating rate obligations from
the issuers or may purchase certificates of participation, a type of floating
or variable rate obligation, which are interests in a pool of debt obligations
held by a bank or other financial institution.
 
WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS. The Funds may purchase when-
issued securities and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. When-issued securities
are securities that have been authorized, but not yet issued. When-issued secu-
rities are purchased in order to secure what is considered to be an advanta-
geous price and yield to a Fund at the time of entering into the transaction. A
forward commitment involves entering into a contract to purchase or sell secu-
rities for a fixed price at a future date beyond the customary settlement peri-
od.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Fund will generally purchase
securities on a when-issued or forward commitment basis with the intention of
acquiring securities for its portfolio, a Fund may dispose of when-issued secu-
rities or forward commitments prior to settlement if the Investment Adviser
deems it appropriate.
 
OTHER INVESTMENT COMPANIES. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Act. These limitations
include a prohibition on any Fund acquiring more than 3% of the voting shares
of any other
 
                                                                              49
<PAGE>
 
 
investment company, and a prohibition on investing more than 5% of a Fund's
total assets in securities of any one investment company or more than 10% of
its total assets in securities of all investment companies. A Fund will indi-
rectly bear its proportionate share of any management fees and other expenses
paid by such other investment companies. Such other investment companies will
have investment objectives, policies and restrictions substantially similar to
those of the acquiring Fund and will be subject to substantially the same
risks.
 
ILLIQUID SECURITIES. Each Fund may invest up to 10% of its net assets in illiq-
uid securities which cannot be disposed of in seven days in the ordinary course
of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
BORROWINGS. Each Fund may borrow up to 33 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
DOWNGRADED SECURITIES. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.

Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Funds. GSAM is referred to in this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Money Market Funds are managed to seek preservation of capital, daily
 liquidity and maximum current income. With each Fund, the Investment Adviser
 follows a conservative, risk-managed investment process that seeks to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 
 1. MANAGING CREDIT RISK
 
 The Investment Adviser's process for managing risk emphasizes:
 .INTENSIVE RESEARCH--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Funds. Sources for their
  analysis include third-party inputs, such as financial statements and media
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .TIMELY UPDATES--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 THE RESULT: AN "APPROVED" LIST OF HIGH-QUALITY CREDITS--The Investment
 Adviser's portfolio management team uses this approval list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
                                                                               1
<PAGE>
 
 
 
 2. MANAGING INTEREST RATE RISK
 
 Three main steps are followed in seeking to manage interest rate risk:
 .ESTABLISH WEIGHTED AVERAGE MATURITY (WAM) TARGET--WAM (the weighted average
  time until the yield of a portfolio reflects any changes in the current
  interest rate environment) is constantly revisited and adjusted as market
  conditions change. An overall strategy is developed by the portfolio
  management team based on insights gained from weekly meetings with both
  Goldman Sachs economists and economists from outside the firm.
 .IMPLEMENT OPTIMUM PORTFOLIO STRUCTURE--Proprietary models that seek the
  optimum balance of risk and return, in conjunction with the Investment
  Adviser's analysis of factors such as market events, short-term interest
  rates and each Fund's asset volatility, are used to identify the most
  effective portfolio structure.
 .CONDUCT RIGOROUS ANALYSIS OF NEW SECURITIES--The Investment Adviser's five-
  step process includes legal, credit, historical index and liquidity
  analysis, as well as price stress testing to determine suitability for
  money market mutual funds.
 
 3. MANAGING LIQUIDITY
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .Each Fund's clients and factors that influence their asset volatility;
 .Technical events that influence the trading range of federal funds and
  other short-term fixed-income markets; and
 .Bid-ask spreads associated with securities in the portfolios.
 
 Benchmarks for the Money Market Funds are the IBC FINANCIAL DATA UNIVERSAL
 AVERAGES. Each Fund tracks the IBC Index which best corresponds to the
 Fund's eligible investments.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 .THE FUNDS: Each Fund's securities are valued by the amortized cost method
  as permitted by Rule 2a-7 under the Investment Company Act of 1940, as
  amended (the "Act"). Under Rule 2a-7, each Fund may invest only in U.S.
  dollar-denominated securities that are determined to present minimal credit
  risk and meet certain other criteria, including conditions relating to
  maturity, diversification and credit quality. These operating policies may
  be more restrictive than the fundamental policies set forth in the State-
  ment of Additional Information (the "Additional Statement").
  .TAXABLE FUNDS: Prime Obligations, Money Market, Premium Money Market,
   Treasury Obligations and Government Funds.
  .TAX-ADVANTAGED FUNDS: Treasury Instruments and Federal Funds.
  .TAX-EXEMPT FUNDS: Tax-Free Money Market and Municipal Money Market Funds.
 .THE INVESTORS: The Funds are designed for institutional investors seeking a
  high rate of return, a stable net asset value ("NAV") and convenient liqui-
  dation privileges. The Funds are particularly suitable for banks, corpora-
  tions and other financial institutions that seek investment of short-term
  funds for their own accounts or for the accounts of their customers. Shares
  of the Government Fund are intended to qualify as eligible investments for
  federally chartered credit unions pursuant to Sections 107(7), 107(8) and
  107(15) of the Federal Credit Union Act, Part 703 of the National Credit
  Union Administration ("NCUA") Rules and Regulations and NCUA Letter Number
  155. The Fund intends to review changes in the applicable laws, rules and
  regulations governing eligible investments for federally chartered credit
  unions, and to take such action as may be necessary so that the investments
  of the Fund qualify as eligible investments under the Federal Credit Union
  Act and the regulations thereunder. Shares of the Government Fund, however,
  may or may not qualify as eligible investments for particular state-chart-
  ered credit unions. A state-chartered credit union should consult qualified
  legal counsel to determine whether the Government Fund is a permissible
  investment under the law applicable to it.
 .NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
 .MAXIMUM REMAINING MATURITY OF PORTFOLIO INVESTMENTS: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .DOLLAR-WEIGHTED AVERAGE PORTFOLIO MATURITY ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .INVESTMENT RESTRICTIONS: Each Fund is subject to certain investment
  restrictions that are described in detail under "Investment Restrictions"
  in the Additional
 
                                                                               3

  Statement. Fundamental investment restrictions of a Fund cannot be changed
  without approval of a majority of the outstanding shares of that Fund. The
  Treasury Obligations Fund's policy of limiting its investments to U.S.
  Treasury Obligations (as defined in Appendix A) and related repurchase
  agreements is also fundamental. All investment objectives and policies not
  specifically designated as fundamental are non-fundamental and may be
  changed without shareholder approval.
 .DIVERSIFICATION: Diversification can help a Fund reduce the risks of
  investing. In accordance with current regulations of the Securities and
  Exchange Commission (the "SEC"), each Fund may not invest more than 5% of
  the value of its total assets at the time of purchase in the securities of
  any single issuer. However, a Fund may invest up to 25% of the value of the
  total assets in the securities of a single issuer for up to three business
  days. These limitations do not apply to cash, certain repurchase agree-
  ments, U.S. Government Securities (as defined in Appendix A) or securities
  of other investment companies. In addition, securities subject to certain
  unconditional guarantees and securities that are not "First Tier Securi-
  ties" as defined by the SEC are subject to different diversification
  requirements as described in the Additional Statement.

Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 The Prime Obligations, Money Market, Premium Money Market, Treasury Obliga-
 tions, Treasury Instruments, Government, Federal, Tax-Free Money Market and
 Municipal Money Market Funds seek to maximize current income to the extent
 consistent with the preservation of capital and the maintenance of liquidity
 by investing exclusively in high quality money market instruments.
 
 
 TAXABLE AND TAX-ADVANTAGED FUNDS:
 The Prime Obligations, Money Market and Premium Money Market Funds pursue
 their investment objectives by investing in U.S. Government Securities,
 obligations of U.S. banks, commercial paper and other short-term obligations
 of U.S. companies, states, municipalities and other entities and repurchase
 agreements. The Money Market and Premium Money Market Funds may also invest
 in U.S. dollar denominated obligations of foreign banks, foreign companies
 and foreign governments. The Treasury Obligations Fund pursues its invest-
 ment objective by investing in securities issued by the U.S. Treasury and
 repurchase agreements relating to such securities. The Government Fund pur-
 sues its investment objective by investing in securities issued by the U.S.
 Government, its agencies, authorities and instrumentalities and repurchase
 agreements relating to such securities. The Treasury Instruments and Federal
 Funds pursue their investment objectives by limiting their investments to
 certain U.S. Treasury Obligations and U.S. Government Securities, respec-
 tively, the interest from which is generally exempt from state income taxa-
 tion. You should consult your tax adviser to determine whether distributions
 from the Treasury Instruments and Federal Funds (and any other Fund that may
 hold such obligations) derived from interest on such obligations are exempt
 from state income taxation in your own state.
 
 In order to obtain a rating from a rating organization, the Prime Obliga-
 tions, Money Market, Premium Money Market, Treasury Obligations, Treasury
 Instruments, Government and Federal Funds will observe special investment
 restrictions.
 
 TAX-EXEMPT FUNDS:
 The Tax-Free Money Market and Municipal Money Market Funds pursue their
 investment objectives by investing in securities issued by or on behalf of
 states, territories, and possessions of the United States and their politi-
 cal subdivisions, agencies, authorities and instrumentalities, and the Dis-
 trict of Columbia, the interest from which, if any, is in the opinion of
 bond counsel excluded from gross income for federal income tax purposes, and
 with respect to the Tax-Free Money Market Fund, not an item of tax prefer-
 ence under the federal alternative minimum tax. With respect to the Munici-
 pal Money Market Fund, such interest may not necessarily be exempt from the
 federal alternative minimum tax ("AMT").

 7 Will only make such investments when yields on such securities are
   attractive compared to other taxable investments.
 8 Ordinarily expect that 100% of a Fund's portfolio securities will be
   invested in municipal obligations, but the Funds may, for temporary
   defensive purposes, hold cash or invest in short-term taxable securities.
 9 To the extent permitted by Rule 2a-7, securities without short-term ratings
   may be purchased if they are deemed to be of comparable quality to First
   Tier Securities, or to the extent that a Fund may purchase Second Tier
   Securities, comparable in quality to Second Tier Securities. In addition, a
   Fund holding a security supported by a guarantee or demand feature may rely
   on the credit quality of the guarantee or demand feature in determining the
   credit quality of the investment.
 10 If such policy should change, private activity bonds subject to AMT would
    not exceed 20% of a Fund's net assets under normal market conditions.

    industrial development bonds or similar obligations where the non-
    governmental entities supplying the revenues from which such bonds or
    obligations are to be paid are in the same industry.

    category by at least two NRSROs, or if only one NRSRO has assigned a
    rating, by that NRSRO; or (b) issued or guaranteed by, or otherwise allow
    a Fund under certain conditions to demand payment from, an entity with
    such ratings. U.S. Government Securities are considered First Tier
    Securities.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

Risks that apply to all Funds:
 
 .NAV RISK--The risk that a Fund will not be able to maintain a NAV per share of
 $1.00 at all times.
 .INTEREST RATE RISK--The risk that during periods of rising interest rates, a
 Fund's yield (and the market value of its securities) will tend to be lower
 than prevailing market rates; in periods of falling interest rates, a Fund's
 yield will tend to be higher.
 .CREDIT/DEFAULT RISK--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Free Money Market and Municipal Money Market Funds, risk of loss from pay-
 ment default may also exist where municipal instruments are backed by foreign
 letters of credit or guarantees.
 .LIQUIDITY RISK--The risk that a Fund will be unable to pay redemption proceeds
 within the time period stated in this Prospectus, because of unusual market
 conditions, an unusually high volume of redemption requests, or other reasons.
 .OTHER RISKS--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Risk that applies to the Prime Obligations, Money Market, Premium Money Market,
Government and Federal Funds:
 
 .U.S. GOVERNMENT SECURITIES RISK--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market and Premium Money Market Funds:
 
 .FOREIGN RISK--The risk that a foreign security could lose value as a result of
 political, financial and economic events in foreign countries, less publicly
 available financial and other information, less stringent foreign securities
 regulations and accounting and disclosure standards, or other factors. The
 Money Market and Premium Money Market Funds may not invest more than 25% of
 their total assets in the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 .BANKING INDUSTRY RISK--The risk that if a Fund invests more than 25% of its
 total assets in bank obligations, an adverse development in the banking indus-
 try may affect the value of the Fund's investments more than if a Fund's
 investments were not invested to such a degree in the banking industry. Nor-
 mally, the Money Market and Premium Money Market Funds intend to invest more
 than 25% of their total assets in bank obligations. Banks may be particularly
 susceptible to certain economic factors such as interest rate changes, adverse
 developments in the real estate market, fiscal and monetary policy and general
 economic cycles.
 
Risks that apply to the Tax-Exempt Funds:
 
 .CONCENTRATION RISK--The risk that if a Fund invests more than 25% of its total
 assets in issuers within the same state, industry or economic sector, an
 adverse economic, business or political development may affect the value of
 the Fund's investments more than if its investments were not so concentrated.
 .TAX RISK--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of a Fund to pay federal tax-
 exempt dividends.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Service
 Shares from year to year; and (b) the average annual returns of a Fund's
 Service Shares. Investors should be aware that the fluctuation of interest
 rates is one primary factor in performance volatility. The bar chart and
 table assume reinvestment of dividends and distributions. A Fund's past per-
 formance is not necessarily an indication of how the Fund will perform in
 the future. Performance reflects expense limitations in effect. If expense
 limitations were not in place, a Fund's performance would have been reduced.
 You may obtain a Fund's current yield by calling 1-800-621-2550. No informa-
 tion has been provided for the Municipal Money Market Fund because it has
 not yet commenced operations.

Fund Fees and Expenses continued
 
/1/The Funds' annual operating expenses are based on actual expenses, except
for the Municipal Money Market Fund which are based on estimated amounts for
the current fiscal year.
/2/The Investment Adviser has voluntarily agreed not to impose a portion of the
management fee on the Funds equal to 0.035% of the Funds' average daily net
assets. AS A RESULT OF FEE WAIVERS, THE CURRENT MANAGEMENT FEES OF THE FUNDS
ARE 0.17% OF THE FUNDS' AVERAGE DAILY NET ASSETS. THE WAIVERS MAY BE TERMINATED
AT ANY TIME AT THE OPTION OF THE INVESTMENT ADVISER.
/3/Service Organizations may charge other fees directly to their customers who
are beneficial owners of Service Shares in connection with their customers'
accounts. Such fees may affect the return customers realize with respect to
their investments.
/4/The Investment Adviser has voluntarily agreed to reduce or limit "Other
Expenses" of each Fund (excluding management fees, service fees, taxes, inter-
est, brokerage fees and litigation, indemnification and other extraordinary
expenses) to 0.01% of each Fund's average daily net assets.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in Service
Shares of a Fund for the time periods indicated and then redeem all of your
shares at the end of those periods. The Example also assumes that your invest-
ment has a 5% return each year and that a Fund's operating expenses remain the
same. Although your actual costs may be higher or lower, based on these assump-
tions your costs would be:

Service Organizations that invest in Service Shares on behalf of their custom-
ers may charge other fees directly to their customer accounts in connection
with their investments. You should contact your Service Organization for infor-
mation regarding such charges. Such fees, if any, may affect the return such
customers realize with respect to their investments.
 
Certain Service Organizations may receive other compensation in connection with
the sale and distribution of Service Shares or for services to their customers'
accounts and/or the Funds. For additional information regarding such compensa-
tion, see "Shareholder Guide" in the Prospectus and "Other Information" in the

 INVESTMENT ADVISER
 
 
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. The Goldman Sachs Group,
 L.P., which controls the Investment Adviser, announced that it will pursue
 an initial public offering of the firm in the late spring or early summer of
 1999. Simultaneously with the offering, the Goldman Sachs Group, L.P. will
 merge into The Goldman Sachs Group, Inc. As of February 28, 1999, GSAM,
 together with its affiliates, acted as investment adviser or distributor for
 assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
 .Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
 .Administers each Fund's business affairs
 .Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)
 
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter
 into principal transactions in certain taxable money market instruments,
 including repurchase agreements, with Goldman Sachs.

  operations.
 
 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
                                                                              29

 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.

Dividends
 
 
Dividends will be distributed to shareholders monthly. You may choose to have
dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time. If you do not indicate any
choice, your dividends and distributions will be reinvested automatically in
the applicable Fund.
 
All or substantially all of each Fund's net investment income will be declared
as a dividend daily. Dividends will normally, but not always, be declared as of
the following times:

Dividends will be reinvested as of the last calendar day of each month. Cash
distributions normally will be paid on or about the first business day of each
month. Net short-term capital gains, if any, will be distributed in accordance
with federal income tax requirements and may be reflected in a Fund's daily
distributions.
 
Each Fund may distribute at least annually other realized capital gains, if
any, after reduction by available capital losses. In order to avoid excessive
fluctuations in the amount of monthly capital gains distributions, a portion of
any net capital gains realized on the disposition of securities during the
months of November and December may be distributed during the subsequent calen-
dar year. Although realized gains and
 
                                                                              31

losses on the assets of a Fund are reflected in the NAV of the Fund, they are
not expected to be of an amount which would affect the Fund's NAV of $1.00 per
share.
 
The income declared as a dividend for the Prime Obligations, Treasury Obliga-
tions, Government and Premium Money Market Funds is based on estimates of net
investment income for each Fund. Actual income may differ from estimates, and
differences, if any, will be included in the calculation of subsequent divi-
dends.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Service
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Service Shares Of The Funds?
 Generally, Service Shares may be purchased only through institutions that
 have agreed to provide account administration and personal and account main-
 tenance services to their customers who are the beneficial owners of Service
 Shares. These institutions are called "Service Organizations." Customers of
 a Service Organization will normally give their purchase instructions to the
 Service Organization, and the Service Organization will, in turn, place pur-
 chase orders with Goldman Sachs. Service Organizations will set times by
 which purchase orders and payments must be received by them from their cus-
 tomers. Generally, Service Shares may be purchased from the Funds on any
 business day at their NAV next determined after receipt of an order by
 Goldman Sachs from a Service Organization. Shares begin earning dividends
 after the Fund's receipt of the purchase amount in federal funds. No sales
 load is charged.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place a purchase order in writing or by telephone.

 Organization should complete and send to Goldman Sachs the Account Applica-

 Service Organizations may send their payments as follows:
 .Wire federal funds to The Northern Trust Company ("Northern"), as sub-cus-
  todian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); OR
 .Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; OR
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds -
  (Name of Fund and Class of Shares), 4900 Sears Tower - 60th Floor, Chicago,
  IL 60606-6372. The Funds will not accept a check drawn on a foreign bank or
  a third-party check.
 
 IT IS STRONGLY RECOMMENDED THAT PAYMENT BE EFFECTED BY WIRING FEDERAL FUNDS
 TO NORTHERN.
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.

 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Service Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers

                                                               SHAREHOLDER GUIDE
 
 .Processing orders to purchase, redeem or exchange shares for customers
 .Responding to inquiries from prospective and existing shareholders
 .Assisting customers with investment procedures
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and may designate other interme-
 diaries to accept such orders, if approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to a service plan adopted by the Trust's Board of Trustees, Service
 Organizations are entitled to receive payment for their services from the
 Trust of up to 0.50% (on an annualized basis) of the average daily net
 assets of the Service Shares of the Funds, which are attributable to or held
 in the name of the Service Organization for its customers.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses.
 
 In addition to Service Shares, each Fund also offers other classes of shares
 to investors. These other share classes are subject to different fees and
 expenses (which affect performance), and are entitled to different services
 than Service Shares. Information regarding these other share classes may be
 obtained from your sales representative or from Goldman Sachs by calling the
 number on the back cover of this Prospectus.

</TABLE>
 
 A Service Organization may impose a minimum amount for initial and subse-
 quent investments in Service Shares and may establish other requirements
 such as a minimum account balance. A Service Organization may redeem Service
 Shares held by non-complying accounts, and may impose a charge for any spe-
 cial services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment and minimum account balance require-
  ment.
 .Reject any purchase order for any reason.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Service Shares
 is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                     (Value of Assets of the Class)
                      - (Liabilities of the Class)

 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Service Shares Of The Funds?
 Generally, Service Shares may be sold (redeemed) only through Service Orga-
 nizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. GENERALLY,
 EACH FUND WILL REDEEM ITS SERVICE SHARES UPON REQUEST ON ANY BUSINESS DAY AT
 THEIR NAV NEXT DETERMINED AFTER RECEIPT OF SUCH REQUEST IN PROPER FORM. A
 Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is elected on the Account
 Application.

 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 NOTE: IT MAY BE DIFFICULT TO MAKE TELEPHONE REDEMPTIONS IN TIMES OF DRASTIC
 ECONOMIC OR MARKET CONDITIONS.

 .Although redemption proceeds will normally be wired as described above,
  each Fund reserves the right to pay redemption proceeds up to three busi-
  ness days following receipt of a properly executed wire transfer redemption
  request. If you are selling shares you recently paid for by check, the Fund
  will pay you when your check has cleared, which may take up to 15 days. If
  the Federal Reserve Bank is closed on the day that the redemption proceeds
  would ordinarily be wired, wiring the redemption proceeds may be delayed
  one additional business day.
 .Neither the Trust nor Goldman Sachs assumes any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organizations.

 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem the Service Shares of any Service Organization whose account balance
  falls below the minimum as a result of a redemption. The Fund will give 60
  days' prior written notice to allow a Service Organization to purchase suf-
  ficient additional shares of the Fund in order to avoid such redemption.
 .Redeem shares in other circumstances determined by the Board of Trustees to
  be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash)
  from the Fund. If you receive redemption proceeds in-kind, you should
  expect to incur transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 
 A Service Organization may exchange Service Shares of a Fund at NAV for
 shares of the corresponding class of any other Goldman Sachs Fund. The
 exchange privilege may be materially modified or withdrawn at any time upon
 60 days' written notice.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirement of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will I Be Sent Regarding Investments In Service
 Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Upon request, Service
 Organizations will also be provided with a printed confirmation for each
 transaction. Any dividends and distributions paid by the Funds are also
 reflected in regular statements issued by the Funds to Service Organiza-
 tions. Service Organizations are responsible for providing these or other
 reports to their customers who are the beneficial owners of Service Shares
 in accordance with the rules that apply to their accounts with the Service
 Organizations.

Taxation
 
 
Each Fund intends to qualify as a regulated investment company for federal tax
purposes, and to distribute to shareholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Funds, Fund dividends will generally be taxable to
you as ordinary income (unless your investment is in an IRA or other tax-
advantaged account) regardless of whether you reinvest in additional shares or
take them as cash. The Tax-Exempt Funds expect generally to distribute "exempt-
interest dividends," which will be tax-exempt income for federal income tax
purposes. The tax status and amounts of the dividends for each calendar year
will be detailed in your annual tax statement from the Funds.
 
Dividends and distributions from each Fund will generally be taxable to you in
the tax year in which they are paid, with one exception. Dividends and distri-
butions declared by a Fund in October, November or December and paid in January
are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry shares of the
Tax-Exempt Funds generally will not be deductible for federal income tax pur-
poses.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Funds may be an item of tax preference for purposes of determining
your AMT liability. Exempt-interest dividends will also be considered along
with other adjusted gross income in determining whether any social security or
railroad retirement payments received by you are subject to federal income tax-
es.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from any Fund (including the Tax-Exempt Funds)
or on the value of the shares held by you. More tax information is provided in
the Additional Statement. You should also consult your own tax adviser for
information regarding all tax consequences applicable to your investments in
the Funds.

Appendix A
Additional Information on Portfolio
Risks, Securities and Techniques
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Funds, including their associated
risks. Additional information is provided in the Additional Statement, which is
available upon request. Among other things, the Additional Statement describes
certain fundamental policies and investment restrictions that cannot be changed
without shareholder approval. You should note, however, that all policies not
specifically designated as fundamental are non-fundamental and may be changed
without shareholder approval. If there is a change in a Fund's investment
objective, you should consider whether that Fund remains an appropriate invest-
ment in light of your then current financial position and needs.
 
U.S. TREASURY OBLIGATIONS AND U.S. GOVERNMENT SECURITIES AND RELATED CUSTODIAL
RECEIPTS. U.S. Treasury Obligations include securities issued or issued or
guaranteed by the U.S. Treasury ("U.S. Treasury Obligations"). Payment of
principal and interest on these obligations is backed by the full faith and
credit of the U.S. government. U.S. Treasury Obligations include, among other
things, the separately traded principal and interest components of securities
guaranteed or issued by the U.S. Treasury if such components are traded
independently under the Separate Trading of Registered Interest and Principal
of Securities program ("STRIPS").
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury Obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.
 
                                                                              43

Some Funds invest in U.S. Treasury Obligations and certain U.S. Government
Securities the interest from which is generally exempt from state income taxa-
tion. Securities generally eligible for this exemption include those issued by
the U.S. Treasury and certain agencies, authorities or instrumentalities of the
U.S. government, including the Federal Home Loan Banks, Federal Farm Credit
Banks, Tennessee Valley Authority and Student Loan Marketing Association.
 
U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Certain Funds may also acquire U.S. Government Securities in the form of custo-
dial receipts. Custodial receipts evidence ownership of future interest pay-
ments, principal payments or both on notes or bonds issued or guaranteed as to
principal or interest by the U.S. government, its agencies, instrumentalities,
political subdivisions or authorities. For certain securities law purposes,
custodial receipts are not considered obligations of the U.S. government.
 
BANK OBLIGATIONS. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. Certain Funds may invest in obligations issued or
backed by U.S. banks when a bank has more than $1 billion in total assets at
the time of purchase or is a branch or subsidiary of such a bank. In addition,
certain Funds may invest in U.S. dollar-denominated obligations issued or
guaranteed by foreign banks that have more than $1 billion in total assets at
the time of purchase, U.S. branches of such foreign banks (Yankee obligations),
foreign branches of such foreign banks and foreign branches of U.S. banks
having more than $1 billion in total assets at the time of purchase. Bank
obligations may be general obligations of the parent bank or may be limited to
the issuing branch by the terms of the specific obligation or by government
regulation.
 
If a Fund invests more than 25% of its total assets in bank obligations
(whether foreign or domestic), it may be especially affected by favorable and
adverse developments in or related to the banking industry. The activities of
U.S. and most foreign banks are subject to comprehensive regulations which, in
the case of U.S. regulations, have undergone substantial changes in the past
decade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of opera-
tions and profitability of domestic and foreign banks. Significant developments
in the U.S. banking industry have included increased competition from other
types of financial institutions, increased acquisition activity and geographic
expansion. Banks may be particularly susceptible to certain economic factors,
such as interest rate changes and adverse developments in the real

                                                                      APPENDIX A
 
estate markets. Fiscal and monetary policy and general economic cycles can
affect the availability and cost of funds, loan demand and asset quality and
thereby impact the earnings and financial conditions of banks.
 
COMMERCIAL PAPER. A Fund may invest in commercial paper, including variable
amount master demand notes and asset-backed commercial paper. Commercial paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, finance companies and other issuers.
The commercial paper purchased by a Fund consists of direct U.S. dollar-denomi-
nated obligations of domestic or, in the case of certain Funds, foreign
issuers.
 
SHORT-TERM OBLIGATIONS. A Fund may invest in other short-term obligations,
including short-term funding agreements payable in U.S. dollars and issued or
guaranteed by U.S. corporations, foreign corporations or other entities. A
funding agreement is a contract between an issuer and a purchaser that obli-
gates the issuer to pay a guaranteed rate of interest on a principal sum depos-
ited by the purchaser. Funding agreements will also guarantee a stream of pay-
ments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and guaran-
teed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Fund will be regarded as
illiquid.
 
ASSET-BACKED AND RECEIVABLES-BACKED SECURITIES. Certain Funds may invest in
asset-backed and receivables-backed securities whose principal and interest
payments are collateralized by pools of assets such as auto loans, credit card
receivables, leases, installment contracts and personal property. Asset-backed
and receivables-backed securities are often subject to more rapid repayment
than their stated maturity date would indicate as a result of the pass-through
of prepayments of principal on the underlying loans. During periods of
declining interest rates, prepayment of loans underlying asset-backed and
receivables-backed securities can be expected to accelerate. Accordingly, a
Fund's ability to maintain positions in such securities will be affected by
reductions in the principal amount of such securities resulting from
prepayments, and its ability to reinvest the returns of principal at comparable
yields is subject to generally prevailing interest rates at that time. In
addition, securities that are backed by credit card, automobile and similar
types of receivables generally do not have the benefit of a security interest
in collateral that is comparable in quality to mortgage assets. There is the
possibility that, in some cases, recoveries on repossessed collateral may not
be available to support payments on these securities. In the event of a
default, a Fund may suffer a loss if it cannot sell collateral quickly and
receive the amount it is owed.
 
FOREIGN GOVERNMENT OBLIGATIONS AND RELATED FOREIGN RISKS. Certain Funds may
invest in foreign government obligations. Foreign government obligations are
U.S. dollar-denominated obligations (limited to commercial paper and other
notes) issued
 
                                                                              45
<PAGE>
 
or guaranteed by a foreign government or other entity located or organized in a
foreign country that maintains a short-term foreign currency rating in the
highest short-term ratings category by the requisite number of NRSROs.
 
Investments by a Fund in foreign securities, whether issued by a foreign gov-
ernment, bank, corporation or other issuer, may present a greater degree of
risk than investments in securities of domestic issuers because of less public-
ly-available financial and other information, less securities regulation,
potential imposition of foreign withholding and other taxes, war, expropriation
or other adverse governmental actions. Efforts in foreign countries to remedi-
ate potential Year 2000 problems are not as extensive as those in the United
States. As a result, the operations of foreign markets, foreign issuers and
foreign governments may be disrupted by the Year 2000 Problem, and the invest-
ment portfolio of a Fund may be adversely affected. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and generally
are not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks.
 
REPURCHASE AGREEMENTS. Certain Funds may enter into repurchase agreements with
primary dealers in U.S. Government Securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund are less than the repurchase price and the Fund's
cost associated with delay and enforcement of the repurchase agreement. In
addition, in the event of bankruptcy of the seller, a Fund could suffer addi-
tional losses if a court determines that the Fund's interest in the collateral
is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, certain Funds, together with other registered
investment companies having advisory agreements with the Investment Adviser or
any of its affiliates, may transfer uninvested cash balances into a single
joint account, the daily aggregate balance of which will be invested in one or
more repurchase agreements.
 
MUNICIPAL OBLIGATIONS. Certain Funds may invest in municipal obligations.
Municipal obligations are issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies,
authorities and instrumentalities, and the District of Columbia. Municipal
obligations may include fixed rate notes and similar debt instruments; variable
and floating rate demand instruments; tax-exempt commercial paper; municipal
bonds; and unrated notes, paper, bonds or other instruments.

                                                                      APPENDIX A
 
 
MUNICIPAL NOTES AND BONDS. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
TENDER OPTION BONDS. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Fund's average portfolio maturity. There is a risk that a Fund will not be con-
sidered the owner of a tender option bond for federal income tax purposes, and
thus will not be entitled to treat such interest as exempt from federal
income tax. Certain tender option bonds may be illiquid or may become illiquid
as a result of a credit rating downgrade, a payment default or a disqualifica-
tion from tax-exempt status.
 
REVENUE ANTICIPATION WARRANTS. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which
 
                                                                              47
<PAGE>
 
 
include a demand feature that permits the holder to sell the RAWs to a bank or
other financial institution at a purchase price equal to par plus accrued
interest on each interest rate reset date.
 
INDUSTRIAL DEVELOPMENT BONDS. Certain Funds may invest in industrial develop-
ment bonds (private activity bonds). Industrial development bonds are a spe-
cific type of revenue bond backed by the credit and security of a private user,
the interest from which would be an item of tax preference when distributed by
a Fund as "exempt-interest dividends" to shareholders under the AMT.
 
OTHER MUNICIPAL OBLIGATION POLICIES. Certain Funds may invest 25% or more of
the value of their respective total assets in municipal obligations which are
related in such a way that an economic, business or political development or
change affecting one municipal obligation would also affect the other municipal
obligation. For example, a Fund may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of a Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political developments affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality of these banks and financial institutions could,
therefore, cause a loss to a Fund that invests in municipal obligations. Let-
ters of credit and other obligations of foreign banks and financial institu-
tions may involve risks in addition to those of domestic obligations because of
less publicly available financial and other information, less securities regu-
lation, potential imposition of foreign withholding and other taxes, war,
expropriation or other adverse governmental actions. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and are gener-
ally not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks. In addition, the Funds may acquire securities in the
form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.

FLOATING AND VARIABLE RATE OBLIGATIONS. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Fund may consider the maturity of a variable or floating rate obli-
gation to be shorter than its ultimate stated maturity if the obligation is a
U.S. Treasury Obligation or U.S. Government Security, if the obligation has a
remaining maturity of 397 calendar days or less, or if the obligation has a
demand feature that permits the Fund to receive payment at any time or at spec-
ified intervals not exceeding 397 calendar days. The issuers or financial
intermediaries providing demand features may support their ability to purchase
the obligations by obtaining credit with liquidity supports. These may include
lines of credit, which are conditional commitments to lend and letters of cred-
it, which will ordinarily be irrevocable, both of which may be issued by domes-
tic banks or foreign banks which have a branch, agency or subsidiary in the
United States. A Fund may purchase variable or floating rate obligations from
the issuers or may purchase certificates of participation, a type of floating
or variable rate obligation, which are interests in a pool of debt obligations
held by a bank or other financial institution.
 
WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS. The Funds may purchase when-
issued securities and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. When-issued securities
are securities that have been authorized, but not yet issued. When-issued secu-
rities are purchased in order to secure what is considered to be an advanta-
geous price and yield to a Fund at the time of entering into the transaction. A
forward commitment involves entering into a contract to purchase or sell secu-
rities for a fixed price at a future date beyond the customary settlement peri-
od.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Fund will generally purchase
securities on a when-issued or forward commitment basis with the intention of
acquiring securities for its portfolio, a Fund may dispose of when-issued secu-
rities or forward commitments prior to settlement if the Investment Adviser
deems it appropriate.
 
OTHER INVESTMENT COMPANIES. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Act. These limitations
include a prohibition on any Fund acquiring more than 3% of the voting shares
of any other investment company, and a prohibition on investing more than 5% of
a Fund's total assets in securities of any one investment company or more than
10% of its total assets in securities of all investment companies. A Fund will

                                                                              49

portionate share of any management fees and other expenses paid by such other
investment companies. Such other investment companies will have investment
objectives, policies and restrictions substantially similar to those of the
acquiring Fund and will be subject to substantially the same risks.
 
ILLIQUID SECURITIES. Each Fund may invest up to 10% of its net assets in illiq-
uid securities which cannot be disposed of in seven days in the ordinary course
of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
BORROWINGS. Each Fund may borrow up to 33 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
DOWNGRADED SECURITIES. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Institutional Liquid Assets Portfolios (the "Funds"). GSAM is referred to in
 this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Money Market Funds are managed to seek preservation of capital, daily
 liquidity and maximum current income. With each Fund the Investment Adviser
 follows a conservative, risk-managed investment process that seeks to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 1. Managing Credit Risk
 
 The Investment Adviser's process for managing risk emphasizes:
 .Intensive research--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Funds. Sources for their
  analysis include third-party inputs, such as financial statements and media
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .Timely updates--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 The Result: An "approved" list of high-quality credits--The Investment
 Adviser's portfolio management team uses this approved list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
 
                                                                               1
<PAGE>
 
 2. Managing Interest Rate Risk
 
 Three main steps are followed in seeking to manage interest rate risk:
 .Establish weighted average maturity (WAM) target--WAM (the weighted average
  time until the yield of a portfolio reflects any changes in the current
  interest rate environment) is constantly revisited and adjusted as market
  conditions change. An overall strategy is developed by the portfolio
  management team based on insights gained from weekly meetings with both
  Goldman Sachs economists and economists from outside the firm.
 .Implement optimum portfolio structure--Proprietary models that seek the
  optimum balance of risk and return, in conjunction with the Investment
  Adviser's analysis of factors such as market events, short-term interest
  rates and each Fund's asset volatility, are used to identify the most
  effective portfolio structure.
 .Conduct rigorous analysis of new securities--The Investment Adviser's five-
  step process includes legal, credit, historical index and liquidity
  analysis, as well as price stress testing to determine suitability for
  money market mutual funds.
 
 
 3. Managing Liquidity
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .Each Fund's clients and factors that influence their asset volatility;
 .Technical events that influence the trading range of federal funds and
  other short-term fixed-income markets; and
 .Bid-ask spreads associated with securities in the portfolios.
 
 Benchmarks for the Money Market Funds are the IBC Financial Data Universal
 Averages. Each Fund tracks the IBC Index which best corresponds to the
 Fund's eligible investments.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 .The Funds: Each Fund's securities are valued by the amortized cost method as
  permitted by Rule 2a-7 under the Investment Company Act of 1940, as amended
  (the "Act"). Under Rule 2a-7, each Fund may invest only in U.S. dollar-
  denominated securities that are determined to present minimal credit risk
  and meet certain other criteria, including conditions relating to maturity,
  diversification and credit quality. These operating policies may be more
  restrictive than the fundamental policies set forth in the Statement of
  Additional Information (the "Additional Statement").
   .Taxable Funds: Prime Obligations, Money Market, Treasury Obligations and
    Government Portfolios.
    .Tax-Advantaged Funds: Treasury Instruments and Federal Portfolios.
   .Tax-Exempt Funds: Tax-Exempt Diversified, Tax-Exempt California and Tax-
    Exempt New York Portfolios.
 .The Investors: The Funds are designed for investors seeking a high rate of
  return, a stable net asset value ("NAV") and convenient liquidation privi-
  leges. The Funds are particularly suitable for banks, corporations and other
  financial institutions that seek investment of short-term funds for their
  own accounts or for the accounts of their customers.
 .NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
 .Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .Investment Restrictions: Each Fund is subject to certain investment restric-
  tions that are described in detail under "Investment Restrictions" in the
  Additional Statement. Fundamental investment restrictions and the investment
  objective of a Fund (except the Tax-Exempt California and Tax-Exempt New
  York Portfolios' objectives of providing shareholders with income exempt
  from California State and New York State and New York City personal income
  tax, respectively) cannot be changed without approval of a majority of the
  outstanding shares of that Fund. The Treasury Obligations Portfolio's policy
  of limiting its investments to U.S. Treasury Obligations (as defined in
  Appendix A) and related repurchase agreements is also fundamental. All
  investment policies not specifically designated as fundamental are non-fun-
  damental and may be changed without shareholder approval.
 .Diversification: Diversification can help a Fund reduce the risks of invest-
  ing. In accordance with current regulations of the Securities and Exchange
  Commission (the "SEC"), each Fund may not invest more than 5% of the value
  of its total assets at the time of purchase in the securities of any single
  issuer with these exceptions: (a) the Tax-Exempt California and Tax-Exempt
  New York Portfolios may each invest up to 25% of their total assets in five
  or fewer issuers; and (b)
 
                                                                               3
<PAGE>
 
  each of the other Funds may invest up to 25% of its total assets in the
  securities of a single issuer for up to three business days. These limita-
  tions do not apply to cash, certain repurchase agreements, U.S. Government
  Securities (as defined in Appendix A) or securities of other investment com-
  panies. In addition, securities subject to certain unconditional guarantees
  and securities that are not "First Tier Securities" as defined by the SEC
  are subject to different diversification requirements as described in the
  Additional Statement.

Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Treasury Obligations, Treasury Instru-
 ments, Government and Federal Portfolios seek to maximize current income to
 the extent consistent with the preservation of capital and the maintenance
 of liquidity by investing exclusively in high quality money market instru-
 ments.
 
 The Prime Obligations and Money Market Portfolios pursue their investment
 objectives by investing in U.S. Government Securities, obligations of U.S.
 banks, commercial paper and other short-term obligations of U.S. companies,
 states, municipalities, and other entities and repurchase agreements. The
 Money Market Portfolio may also invest in U.S. dollar-denominated obliga-
 tions of foreign banks, foreign companies and foreign governments.
 
 The Treasury Obligations Portfolio pursues its investment objective by
 investing in securities issued or guaranteed by the U.S. Treasury and repur-
 chase agreements relating to such securities. The Government Portfolio pur-
 sues its investment objective by investing in U.S. Government Securities and
 repurchase agreements relating to such securities.
 
 The Treasury Instruments and Federal Portfolios pursue their investment
 objectives by limiting their investments to certain U.S. Treasury Obliga-
 tions and U.S. Government Securities, respectively, the interest from which
 is generally exempt from state income taxation. You should consult your tax
 adviser to determine whether distributions from the Treasury Instruments and
 Federal Portfolios (and any other Fund that may hold such obligations)
 derived from interest on such obligations are exempt from state income taxa-
 tion in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
 Portfolios seek to provide shareholders, to the extent consistent with the
 preservation of capital and prescribed portfolio standards, with a high
 level of income exempt from federal income tax by investing primarily in
 municipal instruments.
 
 In addition, the Tax-Exempt California and Tax-Exempt New York Portfolios
 seek to provide shareholders with income exempt from California State and
 New York State and City personal income taxes, respectively.
 
 The Tax-Exempt Funds pursue their investment objectives by investing in
 securities issued by or on behalf of states, territories, and possessions of
 the United States and their political subdivisions, agencies, authorities
 and instrumentalities, and the District of Columbia, the interest from
 which, if any, is in the opinion of bond counsel excluded from gross income
 for federal income tax purposes, and not an item of tax preference under the
 federal alternative minimum tax ("AMT").
 
                                                                               5

 6 Will only make such investments when yields on such securities are
   attractive compared to other taxable investments.
 7 Ordinarily expect that 100% of a Fund's portfolio securities will be
   invested in municipal obligations, but the Funds may, for temporary
   defensive purposes, hold cash or invest in short-term taxable securities.
 8 To the extent permitted by Rule 2a-7, securities without short-term ratings
   may be purchased if they are deemed to be of comparable quality to First
   Tier Securities, or to the extent that a Fund may purchase Second Tier
   Securities, comparable in quality to Second Tier Securities. In addition, a
   Fund holding a security supported by a guarantee or demand feature may rely
   on the credit quality of the guarantee or demand feature in determining the
   credit quality of the investment.
 9 If such policy should change, private activity bonds subject to AMT would
   not exceed 20% of a Fund's net assets under normal market conditions.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

Risks that apply to all Funds:
 
 .NAV Risk--The risk that a Fund will not be able to maintain a NAV per share of
 $1.00 at all times.
 .Interest Rate Risk--The risk that during periods of rising interest rates, a
 Fund's yield (and the market value of its securities) will tend to be lower
 than prevailing market rates; in periods of falling interest rates, a Fund's
 yield will tend to be higher.
 .Credit/Default Risk--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York Portfo-
 lios, risk of loss from payment default may also exist where municipal instru-
 ments are backed by foreign letters of credit or guarantees.
 .Liquidity Risk--The risk that a Fund will be unable to pay redemption proceeds
 within the time period stated in this Prospectus, because of unusual market
 conditions, an unusually high volume of redemption requests, or other reasons.
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Risk that applies to the Prime Obligations, Money Market, Government and
Federal Portfolios:
 
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market Portfolio:
 
 .Foreign Risk--The risk that a foreign security could lose value as a result of
 political, financial and economic events in foreign countries, less publicly
 available financial and other information, less stringent foreign securities
 regulations and accounting and disclosure standards, or other factors. The
 Money Market Portfolio may not invest more than 25% of its total assets in the
 securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
 .Banking Industry Risk--The risk that if the Fund invests more than 25% of its
 total assets in bank obligations, an adverse development in the banking indus-
 try may affect the value of the Fund's investments more than if the Fund's
 investments were not invested to such a degree in the banking industry. Nor-
 mally, the Money Market Portfolio intends to invest more than 25% of its total
 assets in bank obligations. Banks may be particularly susceptible to certain
 economic factors such as interest rate changes, adverse developments in the
 real estate market, fiscal and monetary policy and general economic cycles.
 
Risks that apply to the Tax-Exempt Funds:
 
 .Concentration Risk--The risk that if a Fund invests more than 25% of its total
 assets in issuers within the same state, industry or economic sector, an
 adverse economic, business or political development may affect the value of
 the Fund's investments more than if its investments were not so concentrated.
 The Tax-Exempt California and Tax-Exempt New York Portfolios intend to invest
 at least 65% of their total assets in California municipal obligations and New
 York municipal obligations, respectively. These two Funds are classified as
 "non-diversified" for regulatory purposes.
 .Tax Risk--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of a Fund to pay federal tax-
 exempt dividends (in the case of each of these Funds) and state tax-exempt
 dividends (in the case of the Tax-Exempt California and Tax-Exempt New York
 Portfolios).
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's ILA
 Shares from year to year; and (b) the average annual returns of a Fund's ILA
 Shares. Investors should be aware that the fluctuation of interest rates is
 one primary factor in performance volatility. The bar chart and table assume
 reinvestment of dividends and distributions. A Fund's past performance is
 not necessarily an indication of how the Fund will perform in the future.
 Performance reflects expense limitations in effect. If expense limitations
 were not in place, a Fund's performance would have been reduced. You may
 obtain a Fund's current yield by calling 1-800-621-2550.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the expense limitations) with the cost of investing in other
mutual funds. The Example assumes that you invest $10,000 in ILA Shares of a
Fund for the time periods indicated and then redeem all of your shares at the
end of those periods. The Example also assumes that your investment has a 5%
return each year and that a Fund's operating expenses remain the same. Although
your actual costs may be higher or lower, based on these assumptions your costs
would be:

Institutions that invest in ILA Shares on behalf of their customers may charge
other fees directly to their customer accounts in connection with their invest-
ments. You should contact your institution for information regarding such
charges. Such fees, if any, may affect the return such customers realize with
respect to their investment.
 
Certain institutions that invest in ILA Shares on behalf of their customers may
receive other compensation in connection with the sale and distribution of such
shares or for services to their customers' accounts and/or the Funds. For addi-
tional information regarding such compensation, see "Shareholder Guide" in the
Prospectus and "Other Information" in the Additional Statement.

Service Providers
 
 INVESTMENT ADVISER
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. The Goldman Sachs Group,
 L.P., which controls the Investment Adviser, announced that it will pursue
 an initial public offering of the firm in the late spring or early summer of
 1999. Simultaneously with the offering, the Goldman Sachs Group, L.P. will
 merge into The Goldman Sachs Group, Inc. As of February 28, 1999, GSAM,
 together with its affiliates, acted as investment adviser or distributor for
 assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
 .Continually manages each Fund, including the purchase, retention and
  disposition of securities and other assets
 .Administers each Fund's business affairs
 .Performs various recordholder servicing functions (to the extent not
  provided by other organizations)
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter
 into principal transactions in certain taxable money market instruments,
 including repurchase agreements, with Goldman Sachs.
 
 MANAGEMENT FEES
 
 As compensation for its services and its assumption of certain expenses, the
 Investment Adviser is entitled to the following fees, computed daily and
 payable monthly, at the annual rates listed below:

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.

                                                               SERVICE PROVIDERS
 
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000
 preparedness of the issuers of securities held by the Funds. The Investment
 Adviser may obtain such Year 2000 information from various sources which the
 Investment Adviser believes to be reliable, including the issuers' public
 regulatory filings. However, the Investment Adviser is not in a position to
 verify the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
                                                                              29

Dividends
 
 
 All or substantially all of each Fund's net investment income will be
 declared as a dividend daily. Dividends will normally, but not always, be
 declared as of 4:00 p.m. New York time as a dividend and distributed to
 shareholders monthly. You may choose to have dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 
 You may indicate your election on your Account Application. Any changes may
 be submitted in writing to Goldman Sachs at any time. If you do not indicate
 any choice, your dividends and distributions will be reinvested automati-
 cally in the applicable Fund.
 
 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and December may be distributed during the
 subsequent calendar year. Although realized gains and losses on the assets
 of a Fund are reflected in the NAV of the Fund, they are not expected to be
 of an amount which would affect the Fund's NAV of $1.00 per share.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' ILA Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Shares Of The Funds?
 You may purchase ILA Shares on any business day at their NAV next determined
 after receipt of an order. Shares begin earning dividends after the receipt
 of the purchase amount in federal funds. No sales load is charged. You may
 place a purchase order in writing or by telephone.

</TABLE>
 
 In order to make an initial investment in a Fund, you must furnish to the
 Fund or Goldman Sachs the Account Application attached to this Prospectus.
 
 You may send your payment as follows:
 .Wire federal funds to The Northern Trust Company ("Northern"), as sub-cus-
  todian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; or
 .Send a check or Federal Reserve draft payable to Goldman Sachs
  Funds - (Name of Fund and Class of Shares), 4900 Sears Tower-60th Floor,
  Chicago, Illinois 60606-6372. The Funds will not accept a check drawn on a
  foreign bank or a third-party check.
 
 It is strongly recommended that payment be effected by wiring federal funds
 to Northern.
 
                                                                              31
<PAGE>
 
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.
 
 When Do Shares Begin Earning Dividends?

 chase, redemption and exchange orders placed by or on behalf of their cus-
 tomers and may designate other intermediaries to accept such orders, if
 approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized institution or intermediary on a busi-
  ness day, and the order will be priced at the Fund's NAV next determined
  after such acceptance.
 .Authorized institutions or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your institution or intermediary directly to learn
 whether it is authorized to accept orders for the Trust.
 
 These institutions may receive payments from the Funds or Goldman Sachs for
 the services provided by them with respect to the Funds' ILA Shares. These
 payments may be in addition to other payments borne by the Funds.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-

 Funds. Subject to applicable NASD regulations, the Investment Adviser, Dis-
 tributor and/or their affiliates may also contribute to various cash and
 non-cash incentive arrangements to promote the sale of shares. This addi-
 tional compensation can vary among institutions depending upon such factors
 as the amounts their customers have invested (or may invest) in particular
 Goldman Sachs Funds, the particular program involved, or the amount of reim-
 bursable expenses.
 
 In addition to ILA Shares, each Fund also offers other classes of shares to
 investors. These other share classes are subject to different fees and
 expenses (which affect performance), have different minimum investment
 requirements and are entitled to different services than ILA Shares. Infor-
 mation regarding these other share classes may be obtained from your sales
 representative or from Goldman Sachs by calling the number on the back cover
 of this Prospectus.

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment and minimum account balance require-
  ment.
 .Reject any purchase order for any reason.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange ILA Shares is
 determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________________________
                 Number of Outstanding Shares of the Class
 
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will be priced on any day the
  New York Stock Exchange is open, except for days on which Chicago, Boston
  or New York banks are closed for local holidays.
 
                                                                              33
<PAGE>
 
 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell ILA Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Generally, each Fund will redeem its ILA Shares
 upon request on any business day at their NAV next determined after receipt
 of such request in proper form. You may request that redemption proceeds be
 sent to you by check or by wire (if the wire instructions are on record).
 Redemptions may be requested in writing or by telephone.

 Certain institutions and intermediaries are authorized to accept redemption
 requests on behalf of the Funds as described under "How Do I Purchase Shares
 Through A Financial Institution?" You may also take advantage of the check
 redemption privilege, described below.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
                                                                              35

 .Although redemption proceeds will normally be wired as described above,
  each Fund reserves the right to pay redemption proceeds up to three busi-
  ness days following receipt of a properly executed wire transfer redemption
  request. If you are selling shares you recently paid for by check, the Fund
  will pay you when your check has cleared, which may take up to 15 days. If
  the Federal Reserve Bank is closed on the day that the redemption proceeds
  would ordinarily be wired, wiring the redemption proceeds may be delayed
  one additional business day.
 .To change the bank designated on your Account Application, you must send
  written instructions signed by an authorized person designated on the
  Account Application to the Transfer Agent.
 .Neither the Trust nor Goldman Sachs assumes any responsibility for the per-
  formance of your bank or any intermediaries in the transfer process. If a
  problem with such performance arises, you should deal directly with your
  bank or any such intermediaries.
 
 What Should I Know About The Check Redemption Privilege?
 You may elect to have a special account with State Street for the purpose of
 redeeming ILA Shares from your account by check.
 
36
<PAGE>
 
                                                               SHAREHOLDER GUIDE
 
 The following general policies govern the check redemption privilege:
 .You will be provided with a supply of checks when State Street receives a
  completed signature card and authorization form. Checks drawn on the
  account may be payable to the order of any person in any amount over $500,
  but cannot be certified.
 .The payee of the check may cash or deposit it just like any other check
  drawn on a bank.
 .When the check is presented to State Street for payment, a sufficient num-
  ber of full or fractional ILA Shares will be redeemed to cover the amount
  of the check.
 .Canceled checks will be returned to you by State Street.
 .The check redemption privilege allows you to receive the dividends declared
  on the ILA Shares that are to be redeemed until the check is actually proc-
  essed. Because of this feature, accounts may not be completely liquidated
  by check.
 .If the amount of the check is greater than the value of the ILA Shares held
  in your account, the check will be returned unpaid. In this case, you may
  be subject to extra charges.
 .The Trust reserves the right to limit the availability of, modify or termi-
  nate the check redemption privilege at any time with respect to any or all
  shareholders.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 
 The Trust reserves the right to:
 .Redeem your shares if your account balance falls below the minimum as a
  result of a redemption. The Fund will give you 60 days' prior written
  notice to allow you to purchase sufficient additional shares of the Fund in
  order to avoid such redemption.
 .Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
                                                                              37

 Can I Exchange My Investment From One Fund To Another?
 You may exchange ILA Shares of a Fund at NAV for shares of the corresponding
 class of any other Goldman Sachs Fund. The exchange privilege may be
 materially modified or withdrawn at any time upon 60 days' written notice to
 you.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  to Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.

 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will I Be Sent Regarding Investments In Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact the
 Goldman Sachs Funds at 1-800-621-2550. You will also be provided with an
 individual monthly statement. Upon request, you will be provided with a
 printed confirmation for each transaction in your account. Any dividends and
 distributions paid by the Funds are also reflected in regular statements
 issued by the Funds to recordholders.
 
                                                                              39
<PAGE>
 
Taxation
 
 
Each Fund intends to qualify as a regulated investment company for federal tax
purposes, and to distribute to shareholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Funds, Fund dividends will generally be taxable to
you as ordinary income (unless your investment is in an IRA or other tax-
advantaged account) regardless of whether you reinvest in additional shares or
take them as cash. The Tax-Exempt Funds expect generally to distribute "exempt-
interest dividends," which will be tax-exempt income for federal income tax
purposes. Moreover, the Tax-Exempt California and Tax-Exempt New York Portfo-
lios expect that their dividends will not be subject to the California and New
York state personal income tax, respectively, (and in the case of the Tax-
Exempt New York Portfolio, New York City personal income tax). The tax status
and amounts of the dividends for each calendar year will be detailed in your
annual tax statement from the Funds.
 
Dividends and distributions from each Fund will generally be taxable to you in
the tax year in which they are paid, with one exception. Dividends and distri-
butions declared by a Fund in October, November or December and paid in January
are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry shares of the
Tax-Exempt Funds generally will not be deductible for income tax purposes.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Funds may be an item of tax preference for purposes of determining
your AMT liability. Exempt-interest dividends will also be considered along
with other adjusted gross income in determining whether any social security or
railroad retirement payments received by you are subject to federal income tax-
es.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from any Fund (including the Tax-Exempt Funds)
or on the value of the shares held by you. More tax information is provided in
the Additional Statement. You should also consult your own tax adviser for
information regarding all tax consequences applicable to your investments in
the Funds.

Appendix A
Additional Information on Portfolio
Risks, Securities and Techniques
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Funds, including their associated
risks. Additional information is provided in the Additional Statement, which is
available upon request. Among other things, the Additional Statement describes
certain fundamental policies and investment restrictions that cannot be changed
without shareholder approval. You should note, however, that all policies not
specifically designated as fundamental are non-fundamental and may be changed
without shareholder approval. If there is a change in a Fund's investment
objective, you should consider whether that Fund remains an appropriate invest-
ment in light of your then current financial position and needs.
 
U.S. Treasury Obligations and U.S. Government Securities and Related Custodial
Receipts. U.S. Treasury Obligations include securities issued or issued or
guaranteed by the U.S. Treasury ("U.S. Treasury Obligations"). Payment of
principal and interest on these obligations is backed by the full faith and
credit of the U.S. government. U.S. Treasury Obligations include, among other
things, the separately traded principal and interest components of securities
guaranteed or issued by the U.S. Treasury if such components are traded
independently under the Separate Trading of Registered Interest and Principal
of Securities program ("STRIPS").
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury Obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.
 
                                                                              41

Some Funds invest in U.S. Treasury Obligations and certain U.S. Government
Securities the interest from which is generally exempt from state income taxa-
tion. Securities generally eligible for this exemption include those issued by
the U.S. Treasury and certain agencies, authorities or instrumentalities of the
U.S. government, including the Federal Home Loan Banks, Federal Farm Credit
Banks, Tennessee Valley Authority and Student Loan Marketing Association.
 
U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Certain Funds may also acquire U.S. Government Securities in the form of custo-
dial receipts. Custodial receipts evidence ownership of future interest pay-
ments, principal payments or both on notes or bonds issued or guaranteed as to
principal or interest by the U.S. government, its agencies, instrumentalities,
political subdivisions or authorities. For certain securities law purposes,
custodial receipts are not considered obligations of the U.S. government.
 
Bank Obligations. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. Certain Funds may invest in obligations issued or
backed by U.S. banks when a bank has more than $1 billion in total assets at
the time of purchase or is a branch or subsidiary of such a bank. In addition,
certain Funds may invest in U.S. dollar-denominated obligations issued or
guaranteed by foreign banks that have more than $1 billion in total assets at
the time of purchase, U.S. branches of such foreign banks (Yankee obligations),
foreign branches of such foreign banks and foreign branches of U.S. banks
having more than $1 billion in total assets at the time of purchase. Bank
obligations may be general obligations of the parent bank or may be limited to
the issuing branch by the terms of the specific obligation or by government
regulation.
 
If a Fund invests more than 25% of its total assets in bank obligations
(whether foreign or domestic), it may be especially affected by favorable and
adverse developments in or related to the banking industry. The activities of
U.S. and most foreign banks are subject to comprehensive regulations which, in
the case of U.S. regulations, have undergone substantial changes in the past
decade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of opera-
tions and profitability of domestic and foreign banks. Significant developments
in the U.S. banking industry have included increased competition from other
types of financial institutions, increased acquisition activity and geographic
expansion. Banks may be particularly susceptible to certain economic factors,
such as interest rate changes and adverse developments in the real

estate markets. Fiscal and monetary policy and general economic cycles can
affect the availability and cost of funds, loan demand and asset quality and
thereby impact the earnings and financial conditions of banks.
 
Commercial Paper. A Fund may invest in commercial paper, including variable
amount master demand notes and asset-backed commercial paper. Commercial paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, finance companies and other issuers.
The commercial paper purchased by a Fund consists of direct U.S. dollar-denomi-
nated obligations of domestic or, in the case of certain Funds, foreign
issuers.
 
Short-Term Obligations. A Fund may invest in other short-term obligations,
including short-term funding agreements payable in U.S. dollars and issued or
guaranteed by U.S. corporations, foreign corporations or other entities. A
funding agreement is a contract between an issuer and a purchaser that obli-
gates the issuer to pay a guaranteed rate of interest on a principal sum depos-
ited by the purchaser. Funding agreements will also guarantee a stream of pay-
ments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and guaran-
teed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Fund will be regarded as
illiquid.
 
Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
asset-backed and receivables-backed securities whose principal and interest
payments are collateralized by pools of assets such as auto loans, credit card
receivables, leases, installment contracts and personal property. Asset-backed
and receivables-backed securities are often subject to more rapid repayment
than their stated maturity date would indicate as a result of the pass-through
of prepayments of principal on the underlying loans. During periods of
declining interest rates, prepayment of loans underlying asset-backed and
receivables-backed securities can be expected to accelerate. Accordingly, a
Fund's ability to maintain positions in such securities will be affected by
reductions in the principal amount of such securities resulting from
prepayments, and its ability to reinvest the returns of principal at comparable
yields is subject to generally prevailing interest rates at that time. In
addition, securities that are backed by credit card, automobile and similar
types of receivables generally do not have the benefit of a security interest
in collateral that is comparable in quality to mortgage assets. There is the
possibility that, in some cases, recoveries on repossessed collateral may not
be available to support payments on these securities. In the event of a
default, a Fund may suffer a loss if it cannot sell collateral quickly and
receive the amount it is owed.
 
Foreign Government Obligations and Related Foreign Risks. Certain Funds may
invest in foreign government obligations. Foreign government obligations are
U.S.
 
                                                                              43

dollar-denominated obligations (limited to commercial paper and other notes)
issued or guaranteed by a foreign government or other entity located or
organized in a foreign country that maintains a short-term foreign currency
rating in the highest short-term ratings category by the requisite number of
NRSROs.
 
Investments by a Fund in foreign securities, whether issued by a foreign gov-
ernment, bank, corporation or other issuer, may present a greater degree of
risk than investments in securities of domestic issuers because of less public-
ly-available financial and other information, less securities regulation,
potential imposition of foreign withholding and other taxes, war, expropriation
or other adverse governmental actions. Efforts in foreign countries to remedi-
ate potential Year 2000 problems are not as extensive as those in the United
States. As a result, the operations of foreign markets, foreign issuers and
foreign governments may be disrupted by the Year 2000 Problem, and the invest-
ment portfolio of a Fund may be adversely affected. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and generally
are not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks.
 
Repurchase Agreements. Certain Funds may enter into repurchase agreements with
primary dealers in U.S. Government Securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund are less than the repurchase price and the Fund's
cost associated with delay and enforcement of the repurchase agreement. In
addition, in the event of bankruptcy of the seller, a Fund could suffer addi-
tional losses if a court determines that the Fund's interest in the collateral
is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, certain Funds, together with other registered
investment companies having advisory agreements with the Investment Adviser or
any of its affiliates, may transfer uninvested cash balances into a single
joint account, the daily aggregate balance of which will be invested in one or
more repurchase agreements.
 
Municipal Obligations. Certain Funds may invest in municipal obligations.
Municipal obligations are issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies,
authorities and instrumentalities, and the District of Columbia. Municipal
obligations may include fixed rate notes and similar debt instruments; variable
and floating rate demand instruments; tax-exempt commercial paper; municipal
bonds; and unrated notes, paper, bonds or other instruments.

                                                                      APPENDIX A
 
 
Municipal Notes and Bonds. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
Tender Option Bonds. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Fund's average portfolio maturity. There is a risk that a Fund will not be con-
sidered the owner of a tender option bond for federal income tax purposes, and
thus will not be entitled to treat such interest as exempt from federal
income tax. Certain tender option bonds may be illiquid or may become illiquid
as a result of a credit rating downgrade, a payment default or a disqualifica-
tion from tax-exempt status.
 
Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which
 
                                                                              45
<PAGE>
 
 
include a demand feature that permits the holder to sell the RAWs to a bank or
other financial institution at a purchase price equal to par plus accrued
interest on each interest rate reset date.
 
Industrial Development Bonds. Certain Funds may invest in industrial develop-
ment bonds (private activity bonds). Industrial development bonds are a spe-
cific type of revenue bond backed by the credit and security of a private user,
the interest from which would be an item of tax preference when distributed by
a Fund as "exempt-interest dividends" to shareholders under the AMT.
 
Other Municipal Obligation Policies. Certain Funds may invest 25% or more of
the value of their respective total assets in municipal obligations which are
related in such a way that an economic, business or political development or
change affecting one municipal obligation would also affect the other municipal
obligation. For example, a Fund may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of a Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political developments affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality of these banks and financial institutions could,
therefore, cause a loss to a Fund that invests in municipal obligations. Let-
ters of credit and other obligations of foreign banks and financial institu-
tions may involve risks in addition to those of domestic obligations because of
less publicly available financial and other information, less securities regu-
lation, potential imposition of foreign withholding and other taxes, war,
expropriation or other adverse governmental actions. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and are gener-
ally not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks. In addition, the Funds may acquire securities in the
form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.

Floating and Variable Rate Obligations. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Fund may consider the maturity of a variable or floating rate obli-
gation to be shorter than its ultimate stated maturity if the obligation is a
U.S. Treasury Obligation or U.S. Government Security, if the obligation has a
remaining maturity of 397 calendar days or less, or if the obligation has a
demand feature that permits the Fund to receive payment at any time or at spec-
ified intervals not exceeding 397 calendar days. The issuers or financial
intermediaries providing demand features may support their ability to purchase
the obligations by obtaining credit with liquidity supports. These may include
lines of credit, which are conditional commitments to lend and letters of cred-
it, which will ordinarily be irrevocable, both of which may be issued by domes-
tic banks or foreign banks which have a branch, agency or subsidiary in the
United States. A Fund may purchase variable or floating rate obligations from
the issuers or may purchase certificates of participation, a type of floating
or variable rate obligation, which are interests in a pool of debt obligations
held by a bank or other financial institution.
 
When-Issued Securities and Forward Commitments. The Funds may purchase when-
issued securities and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. When-issued securities
are securities that have been authorized, but not yet issued. When-issued secu-
rities are purchased in order to secure what is considered to be an advanta-
geous price and yield to a Fund at the time of entering into the transaction. A
forward commitment involves entering into a contract to purchase or sell secu-
rities for a fixed price at a future date beyond the customary settlement peri-
od.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Fund will generally purchase
securities on a when-issued or forward commitment basis with the intention of
acquiring securities for its portfolio, a Fund may dispose of when-issued secu-
rities or forward commitments prior to settlement if the Investment Adviser
deems it appropriate.
 
Other Investment Companies. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Act. These limitations
include a prohibition on any Fund acquiring more than 3% of the voting shares
of any other investment company, and a prohibition on investing more than 5% of
a Fund's total assets in securities of any one investment company or more than
10% of its total assets in securities of all investment companies. A Fund will
indirectly bear its proportionate share of any management fees and other
expenses paid by such other investment companies. Such other investment compa-
nies will have investment objectives,
 
                                                                              47
<PAGE>
 
 
policies and restrictions substantially similar to those of the acquiring Fund
and will be subject to substantially the same risks.
 
Illiquid Securities. Each Fund may invest up to 10% of its net assets in illiq-
uid securities which cannot be disposed of in seven days in the ordinary course
of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
Downgraded Securities. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.
 
Special Risks and Policies Applicable to the Tax-Exempt Funds:
 
Fundamental Policies. As a matter of fundamental policy, at least 80% of each
of the net assets of each of the Tax-Exempt Diversified, Tax-Exempt California
and Tax-Exempt New York Portfolios will ordinarily be invested in municipal
obligations, the interest from which is, in the opinion of bond counsel, if
any, excluded from gross income for federal income tax purposes. In addition,
as a matter of fundamental policy, at least 65% of each of the Tax-Exempt Cali-
fornia and Tax-Exempt New York Portfolio's total assets will be invested in
California and New York municipal obligations, except in extraordinary circum-
stances.
 
For these purposes, California and New York municipal obligations are obliga-
tions issued by or on behalf of the State of California or the State of New
York, respectively, and their respective political subdivisions, agencies and
instrumentalities and the government of Puerto Rico, the U.S. Virgin Islands
and Guam, the interest from

                                                                      APPENDIX A
 
which is excluded from gross income for federal income tax purposes and is
exempt from California State personal income tax or New York State and New York
City personal income tax. Each Tax-Exempt Fund may temporarily invest in tax-
able money market instruments or, in the case of the Tax-Exempt California and
New York Portfolios, in municipal obligations that are not California or New
York municipal obligations, respectively, when acceptable California and New
York municipal obligations are not available or when the Investment Adviser
believes that the market conditions dictate a defensive posture. Investments in
taxable money market instruments will be limited to those meeting the quality
standards of each Tax-Exempt Fund. The Tax-Exempt California and Tax-Exempt New
York Portfolios' distributions of interest from municipal obligations other
than California and New York municipal obligations, respectively, may be sub-
ject to California and New York State and New York City personal income taxes.
 
Risks of Investing in California and New York: The Tax-Exempt California and
Tax-Exempt New York Portfolios concentrate their investments in California and
New York municipal obligations. Consequently, these Funds are more susceptible
to factors adversely affecting issuers of California and New York municipal
obligations, and may be riskier than comparable municipal bond funds and money
market funds that do not emphasize these issuers to this degree.
 
The Tax-Exempt California Portfolio's investments can be affected by political
and economic developments within the State of California (the "State"), and by
the financial condition of the State, its public authorities and political sub-
divisions. After suffering a severe recession in the early 1990's which caused
the State to experience financial difficulties, California's economy entered a
sustained recovery since late 1993 and the State's budget has returned to a
positive balance. California's long-term credit rating has been raised after
being reduced during the recession. To respond to its own revenue shortfalls
during the recession, the State reduced assistance to its public authorities
and political subdivisions. Cutbacks in state aid could further adversely
affect the financial condition of cities, counties and education districts
which are subject to their own fiscal constraints. California voters in the
past have passed amendments to the California Constitution and other measures
that limit the taxing and spending authority of California governmental enti-
ties, and future voter initiatives could result in adverse consequences affect-
ing California municipal obligations. Also, the ultimate fiscal effect of fed-
erally-mandated reform of welfare programs on the State and its local
governments is still to be resolved.
 
                                                                              49
<PAGE>
 
 
 
These factors, among others (including the outcome of related pending litiga-
tion), could reduce the credit standing of certain issuers of California munic-
ipal obligations. A more detailed discussion of the risks of investing in Cali-
fornia is included in the Additional Statement.
 
The Tax-Exempt New York Portfolio's investments will be affected by political
and economic developments within the State of New York (the "State"), and by
the financial conditions of the State, its public authorities and political
subdivisions, particularly the City of New York (the "City"). The State and the
City face long-term economic problems that could seriously affect their ability
and that of other issuers of New York municipal obligations to meet their
financial obligations. Certain substantial issuers of New York municipal obli-
gations (including issuers whose obligations may be acquired by the Fund) have
experienced serious financial difficulties in recent years. These difficulties
have at times jeopardized the credit standing and impaired the borrowing abili-
ties of all New York issuers and have generally contributed to higher interest
costs for their borrowings and fewer markets for their outstanding debt obliga-
tions. Although several different issues of municipal obligations of the State
and its agencies and instrumentalities and of the City have been downgraded by
S&P and Moody's in recent years, S&P and Moody's have recently placed the debt
obligations of the State on Credit Watch with positive implications and
upgraded the debt obligations of the City, respectively. Strong demand for New
York municipal obligations has also at times had the effect of permitting New
York municipal obligations to be issued with yields relatively lower, and after
issuance, to trade in the market at prices relatively higher, than comparably
rated municipal obligations issued by other jurisdictions. A recurrence of the
financial difficulties previously experienced by certain issuers of New York
municipal obligations could result in defaults or declines in the market values
of those issuers' existing obligations and, possibly, in the obligations of
other issuers of New York municipal obligations. Although as of April 1, 1999
no issuers were in default with respect to the payment of their New York munic-
ipal obligations, the occurrence of any such default could materially affect
adversely the market values and marketability of all New York municipal obliga-
tions and, consequently, the value of the Fund's holdings. A more detailed dis-
cussion of the risks of investing in New York is included in the Additional
Statement.
 
If California, New York, or any of their local governmental entities are unable
to meet their financial obligations, the corresponding Fund's income, NAV,
ability to preserve or realize appreciation of capital or liquidity could be
adversely affected. Also, neither of these Funds is a diversified fund under
the Act (except to the extent that diversification is required by Rule 2a-7 or
for federal income tax purposes).

Because they may invest a larger percentage of their assets in the securities
of fewer issuers than do diversified funds, these Funds may be exposed to
greater risk in that an adverse change in the condition of one or a small num-
ber of issuers would have a greater impact on them.
 
                                                                              51

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Institutional Liquid Assets Portfolios (the "Funds"). GSAM is referred to in
 this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Money Market Funds are managed to seek preservation of capital, daily
 liquidity and maximum current income. With each Fund the Investment Adviser
 follows a conservative, risk-managed investment process that seeks to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 1.  Managing Credit Risk
 
 The Investment Adviser's process for managing risk emphasizes:
 .Intensive research--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Funds. Sources for their
  analysis include third-party inputs, such as financial statements and media
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .Timely updates--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 The Result: An "approved" list of high-quality credits--The Investment
 Adviser's portfolio management team uses this approved list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
 
                                                                               1
<PAGE>
 
 2.  Managing Interest Rate Risk
 
 Three main steps are followed in seeking to manage interest rate risk:
 .Establish weighted average maturity (WAM) target--WAM (the weighted average
  time until the yield of a portfolio reflects any changes in the current
  interest rate environment) is constantly revisited and adjusted as market
  conditions change. An overall strategy is developed by the portfolio
  management team based on insights gained from weekly meetings with both
  Goldman Sachs economists and economists from outside the firm.
 .Implement optimum portfolio structure--Proprietary models that seek the
  optimum balance of risk and return, in conjunction with the Investment
  Adviser's analysis of factors such as market events, short-term interest
  rates and each Fund's asset volatility, are used to identify the most
  effective portfolio structure.
 .Conduct rigorous analysis of new securities--The Investment Adviser's five-
  step process includes legal, credit, historical index and liquidity
  analysis, as well as price stress testing to determine suitability for
  money market mutual funds.
 
 
 3. Managing Liquidity
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .Each Fund's clients and factors that influence their asset volatility;
 .Technical events that influence the trading range of federal funds and
  other short-term fixed-income markets; and
 .Bid-ask spreads associated with securities in the portfolios.
 
 Benchmarks for the Money Market Funds are the IBC Financial Data Universal
 Averages. Each Fund tracks the IBC Index which best corresponds to the
 Fund's eligible investments.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 .The Funds: Each Fund's securities are valued by the amortized cost method as
  permitted by Rule 2a-7 under the Investment Company Act of 1940, as amended
  (the "Act"). Under Rule 2a-7, each Fund may invest only in U.S. dollar-
  denominated securities that are determined to present minimal credit risk
  and meet certain other criteria, including conditions relating to maturity,
  diversification and credit quality. These operating policies may be more
  restrictive than the fundamental policies set forth in the Statement of
  Additional Information (the "Additional Statement").
   .Taxable Funds: Prime Obligations, Money Market, Treasury Obligations and
    Government Portfolios.
    .Tax-Advantaged Funds: Treasury Instruments and Federal Portfolios.
   .Tax-Exempt Funds: Tax-Exempt Diversified, Tax-Exempt California and Tax-
    Exempt New York Portfolios.
 .The Investors: The Funds are designed for investors seeking a high rate of
  return, a stable net asset value ("NAV") and convenient liquidation privi-
  leges. The Funds are particularly suitable for banks, corporations and other
  financial institutions that seek investment of short-term funds for their
  own accounts or for the accounts of their customers.
 .NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
 .Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .Investment Restrictions: Each Fund is subject to certain investment restric-
  tions that are described in detail under "Investment Restrictions" in the
  Additional Statement. Fundamental investment restrictions and the investment
  objective of a Fund (except the Tax-Exempt California and Tax-Exempt New
  York Portfolios' objectives of providing shareholders with income exempt
  from California State and New York State and New York City personal income
  tax, respectively) cannot be changed without approval of a majority of the
  outstanding shares of that Fund. The Treasury Obligations Portfolio's policy
  of limiting its investments to U.S. Treasury Obligations (as defined in
  Appendix A) and related repurchase agreements is also fundamental. All
  investment policies not specifically designated as fundamental are non-fun-
  damental and may be changed without shareholder approval.
 .Diversification: Diversification can help a Fund reduce the risks of invest-
  ing. In accordance with current regulations of the Securities and Exchange
  Commission (the "SEC"), each Fund may not invest more than 5% of the value
  of its total assets at the time of purchase in the securities of any single
  issuer with these exceptions: (a) the Tax-Exempt California and Tax-Exempt
  New York Portfolios may each invest up to 25% of their total assets in five
  or fewer issuers; and (b)
 
                                                                               3
<PAGE>
 
  each of the other Funds may invest up to 25% of its total assets in the
  securities of a single issuer for up to three business days. These limita-
  tions do not apply to cash, certain repurchase agreements, U.S. Government
  Securities (as defined in Appendix A) or securities of other investment com-
  panies. In addition, securities subject to certain unconditional guarantees
  and securities that are not "First Tier Securities" as defined by the SEC
  are subject to different diversification requirements as described in the
  Additional Statement.

Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Treasury Obligations, Treasury Instru-
 ments, Government and Federal Portfolios seek to maximize current income to
 the extent consistent with the preservation of capital and the maintenance
 of liquidity by investing exclusively in high quality money market instru-
 ments.
 
 The Prime Obligations and Money Market Portfolios pursue their investment
 objectives by investing in U.S. Government Securities, obligations of U.S.
 banks, commercial paper and other short-term obligations of U.S. companies,
 states, municipalities and other entities and repurchase agreements. The
 Money Market Portfolio may also invest in U.S. dollar-denominated obliga-
 tions of foreign banks, foreign companies and foreign governments.
 
 The Treasury Obligations Portfolio pursues its investment objective by
 investing in securities issued or guaranteed by the U.S. Treasury and repur-
 chase agreements relating to such securities. The Government Portfolio pur-
 sues its investment objective by investing in U.S. Government Securities and
 repurchase agreements relating to such securities.
 
 The Treasury Instruments and Federal Portfolios pursue their investment
 objectives by limiting their investments to certain U.S. Treasury Obliga-
 tions and U.S. Government Securities, respectively, the interest from which
 is generally exempt from state income taxation. You should consult your tax
 adviser to determine whether distributions from the Treasury Instruments and
 Federal Portfolios (and any other Fund that may hold such obligations)
 derived from interest on such obligations are exempt from state income taxa-
 tion in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
 Portfolios seek to provide shareholders, to the extent consistent with the
 preservation of capital and prescribed portfolio standards, with a high
 level of income exempt from federal income tax by investing primarily in
 municipal instruments.
 
 In addition, the Tax-Exempt California and Tax-Exempt New York Portfolios
 seek to provide shareholders with income exempt from California State and
 New York State and City personal income taxes, respectively.
 
 The Tax-Exempt Funds pursue their investment objectives by investing in
 securities issued by or on behalf of states, territories, and possessions of
 the United States and their political subdivisions, agencies, authorities
 and instrumentalities, and the District of Columbia, the interest from
 which, if any, is in the opinion of bond counsel excluded from gross income
 for federal income tax purposes, and not an item of tax preference under the
 federal alternative minimum tax ("AMT").
 
                                                                               5

 6 Will only make such investments when yields on such securities are
   attractive compared to other taxable investments.
 7 Ordinarily expect that 100% of a Fund's portfolio securities will be
   invested in municipal obligations, but the Funds may, for temporary
   defensive purposes, hold cash or invest in short-term taxable securities.
 8 To the extent permitted by Rule 2a-7, securities without short-term ratings
   may be purchased if they are deemed to be of comparable quality to First
   Tier Securities, or to the extent that a Fund may purchase Second Tier
   Securities, comparable in quality to Second Tier Securities. In addition, a
   Fund holding a security supported by a guarantee or demand feature may rely
   on the credit quality of the guarantee or demand feature in determining the
   credit quality of the investment.
 9 If such policy should change, private activity bonds subject to AMT would
   not exceed 20% of a Fund's net assets under normal market conditions.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

Risks that apply to all Funds:
 
 .NAV Risk--The risk that a Fund will not be able to maintain a NAV per share of
 $1.00 at all times.
 .Interest Rate Risk--The risk that during periods of rising interest rates, a
 Fund's yield (and the market value of its securities) will tend to be lower
 than prevailing market rates; in periods of falling interest rates, a Fund's
 yield will tend to be higher.
 .Credit/Default Risk--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York Portfo-
 lios, risk of loss from payment default may also exist where municipal instru-
 ments are backed by foreign letters of credit or guarantees.
 .Liquidity Risk--The risk that a Fund will be unable to pay redemption proceeds
 within the time period stated in this Prospectus, because of unusual market
 conditions, an unusually high volume of redemption requests, or other reasons.
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Risk that applies to the Prime Obligations, Money Market, Government and
Federal Portfolios:
 
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market Portfolio:
 
 .Foreign Risk--The risk that a foreign security could lose value as a result of
 political, financial and economic events in foreign countries, less publicly
 available financial and other information, less stringent foreign securities
 regulations and accounting and disclosure standards, or other factors. The
 Money Market Portfolio may not invest more than 25% of its total assets in the
 securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
 .Banking Industry Risk--The risk that if the Fund invests more than 25% of its
 total assets in bank obligations, an adverse development in the banking indus-
 try may affect the value of the Fund's investments more than if the Fund's
 investments were not invested to such a degree in the banking industry. Nor-
 mally, the Money Market Portfolio intends to invest more than 25% of its total
 assets in bank obligations. Banks may be particularly susceptible to certain
 economic factors such as interest rate changes, adverse developments in the
 real estate market, fiscal and monetary policy and general economic cycles.
 
Risks that apply to the Tax-Exempt Funds:
 
 .Concentration Risk--The risk that if a Fund invests more than 25% of its total
 assets in issuers within the same state, industry or economic sector, an
 adverse economic, business or political development may affect the value of
 the Fund's investments more than if its investments were not so concentrated.
 The Tax-Exempt California and Tax-Exempt New York Portfolios intend to invest
 at least 65% of their total assets in California municipal obligations and New
 York municipal obligations, respectively. These two Funds are classified as
 "non-diversified" for regulatory purposes.
 .Tax Risk--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of a Fund to pay federal tax-
 exempt dividends (in the case of each of these Funds) and state tax-exempt
 dividends (in the case of the Tax-Exempt California and Tax-Exempt New York
 Portfolios).
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Admin-
 istration Shares from year to year; and (b) the average annual returns of a
 Fund's Administration Shares. Investors should be aware that the fluctuation
 of interest rates is one primary factor in performance volatility. The bar
 chart and table assume reinvestment of dividends and distributions. A Fund's
 past performance is not necessarily an indication of how the Fund will per-
 form in the future. Performance reflects expense limitations in effect. If
 expense limitations were not in place, a Fund's performance would have been
 reduced. You may obtain a Fund's current yield by calling 1-800-621-2550.

are the beneficial owners of Administration Shares in connection with their
customers' accounts. Such fees may affect the return such customers realize
with respect to their investments.
/3/"Other Expenses" include transfer agency fees equal to 0.04% of the average
daily net assets of each Fund's Administration Shares plus all other ordinary
expenses not detailed above.
/4/The Investment Adviser has voluntarily agreed to reduce or limit "Total
Portfolio Operating Expenses" of each Fund (excluding administration fees,
taxes, interest, brokerage fees, litigation, indemnification and other
extraordinary expenses) to 0.43% of each Fund's average daily net assets. As a
result of the current expense limitations, "Other Expenses" and "Total Fund
Operating Expenses" of the Funds which are actually incurred are as set forth
below. The expense limitations may be terminated at any time at the option of
the Investment Adviser with the approval of the Trustees. If this occurs,
"Other Expenses" and "Total Fund Operating Expenses" may increase without
shareholder approval.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the expense limitations) with the cost of investing in other
mutual funds. The Example assumes that you invest $10,000 in Administration
Shares of a Fund for the time periods indicated and then redeem all of your
Shares at the end of those periods. The Example also assumes that your invest-
ment has a 5% return each year and that a Fund's operating expenses remain the
same. Although your actual costs may be higher or lower, based on these assump-
tions your costs would be:

Service Providers
 
 INVESTMENT ADVISER
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. The Goldman Sachs Group,
 L.P., which controls the Investment Adviser, announced that it will pursue
 an initial public offering of the firm in the late spring or early summer of
 1999. Simultaneously with the offering, the Goldman Sachs Group, L.P. will
 merge into The Goldman Sachs Group, Inc. As of February 28, 1999, GSAM,
 together with its affiliates, acted as investment adviser or distributor for
 assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
 .Continually manages each Fund, including the purchase, retention and
  disposition of securities and other assets
 .Administers each Fund's business affairs
 .Performs various recordholder servicing functions (to the extent not
  provided by other organizations)
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter
 into principal transactions in certain taxable money market instruments,
 including repurchase agreements, with Goldman Sachs.
 
 MANAGEMENT FEES
 
 As compensation for its services and its assumption of certain expenses, the
 Investment Adviser is entitled to the following fees, computed daily and
 payable monthly, at the annual rates listed below:

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.

<PAGE>
 
                                                               SERVICE PROVIDERS
 
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000
 preparedness of the issuers of securities held by the Funds. The Investment
 Adviser may obtain such Year 2000 information from various sources which the
 Investment Adviser believes to be reliable, including the issuers' public
 regulatory filings. However, the Investment Adviser is not in a position to
 verify the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
                                                                              29

Dividends
 
 
 All or substantially all of each Fund's net investment income will be
 declared as a dividend daily. Dividends will normally, but not always, be
 declared as of 4:00 p.m. New York time as a dividend and distributed to
 shareholders monthly. You may choose to have dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 
 You may indicate your election on your Account Application. Any changes may
 be submitted in writing to Goldman Sachs at any time. If you do not indicate
 any choice, your dividends and distributions will be reinvested automati-
 cally in the applicable Fund.
 
 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and December may be distributed during the
 subsequent calendar year. Although realized gains and losses on the assets
 of a Fund are reflected in the NAV of the Fund, they are not expected to be
 of an amount which would affect the Fund's NAV of $1.00 per share.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Administration
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Administration Shares Of The Funds?
 Generally, Administration Shares may be purchased only through institutions
 that have agreed to provide account administration and maintenance services
 to their customers who are the beneficial owners of Administration Shares.
 These institutions are called "Service Organizations." Customers of a Serv-
 ice Organization will normally give their purchase instructions to the Serv-
 ice Organization, and the Service Organization will, in turn, place purchase
 orders with Goldman Sachs. Service Organizations will set times by which
 purchase orders and payments must be received by them from their customers.
 Generally, Administration Shares may be purchased from the Funds on any
 business day at their NAV next determined after receipt of an order by
 Goldman Sachs from a Service Organization. Shares begin earning dividends
 after the Fund's receipt of the purchase amount in federal funds. No sales
 load is charged.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place a purchase order in writing or by telephone.

 Before or immediately after placing an initial purchase order, a Service
 Organization should complete and send to Goldman Sachs the Account Applica-
 tion attached to this Prospectus.
 
                                                                              31
<PAGE>
 
 Service Organizations may send their payments as follows:
 .Wire federal funds to The Northern Trust Company ("Northern"), as sub-cus-
  todian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds -
  (Name of Fund and Class of Shares), 4900 Sears Tower - 60th Floor, Chicago,
  IL 60606-6372. The Funds will not accept a check drawn on a foreign bank or
  a third-party check.
 
 It is strongly recommended that payment be effected by wiring federal funds
 to Northern.
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.
 
 When Do Shares Begin Earning Dividends?
 
 Dividends begin to accrue as follows:

 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Administration Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and may designate other interme-
 diaries to accept such orders, if approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a
 
32

                                                               SHAREHOLDER GUIDE
 
  business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to an administration plan adopted by the Trust's Board of Trustees,
 Service Organizations are entitled to receive payment for their services
 from the Trust of up to 0.15% (on an annualized basis) of the average daily
 net assets of the Administration Shares of the Funds, which are attributable
 to or held in the name of the Service Organization for its customers. In
 addition, GSAM, at its own expense, may pay a Service Organization, up to
 0.10% of the average daily net assets of the Administration Shares of the
 Fund, which are attributable to or held in the name of the Service Organiza-
 tion for its customers. Such compensation does not represent an additional
 expense to a Fund or its shareholders, since it will be paid from the assets
 of GSAM.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses.
 
 In addition to Administration Shares, each Fund also offers other classes of
 shares to investors. These other share classes are subject to different fees
 and expenses (which affect performance), have different minimum investment
 requirements and are entitled to different services than Administration
 Shares. Information regarding these other share classes may be obtained from
 your sales representative or from Goldman Sachs by calling the number on the
 back cover of this Prospectus.
 
 What Is My Minimum Investment In The Funds?
 The Funds do not have any minimum purchase or account requirements with
 respect to Administration Shares. A Service Organization may, however,
 impose a minimum amount for initial and subsequent investments in Adminis-
 tration Shares,
 
                                                                              33
<PAGE>
 
 
 and may establish other requirements such as a minimum account balance. A
 Service Organization may redeem Administration Shares held by non-complying
 accounts, and may impose a charge for any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment and minimum account balance require-
  ment.
 .Reject any purchase order for any reason.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Administration
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                    (Value of Assets of the Class)
                     - (Liabilities of the Class)
      NAV = _______________________________________________________
                   Number of Outstanding Shares of the Class
 
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will be priced on any day the
  New York Stock Exchange is open, except for days on which Chicago, Boston
  or New York banks are closed for local holidays.
 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.

 HOW TO SELL SHARES
 
 How Can I Sell Administration Shares Of The Funds?
 Generally, Administration Shares may be sold (redeemed) only through Service
 Organizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. Generally,
 each Fund will redeem its Administration Shares upon request on any business
 day at their NAV next determined after receipt of such request in proper
 form. A Service Organization may request redemptions in writing or by tele-
 phone if the optional telephone redemption privilege is elected on the
 Account Application.

 Certain Service Organizations are authorized to accept redemption requests
 on behalf of the Funds as described under "What Do I Need To Know About
 Service Organizations?" A redemption may also be made with respect to cer-
 tain Funds by means of the check redemption privilege.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
  .All telephone requests are recorded.
  .Any redemption request that requires money to go to an account or address
   other than that designated on the Account Application must be in writing
   and signed by an authorized person designated on the Account Application.
   The written request may be confirmed by telephone with both the request-
   ing party and the designated bank account to verify instructions.
  .The telephone redemption option may be modified or terminated at any
   time.
 
  Note: It may be difficult to make telephone redemptions in times of dras-
  tic economic or market conditions.
 
                                                                              35

 .Although redemption proceeds will normally be wired as described above,
  each Fund reserves the right to pay redemption proceeds up to three busi-
  ness days following receipt of a properly executed wire transfer redemption
  request. If you are selling shares you recently paid for by check, the Fund
  will pay you when your check has cleared, which may take up to 15 days. If
  the Federal Reserve Bank is closed on the day that the redemption proceeds
  would ordinarily be wired, wiring the redemption proceeds may be delayed
  one additional business day.
 .Neither the Trust nor Goldman Sachs assumes any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organizations.
 
 What Should I Know About The Check Redemption Privilege?
 A Service Organization may elect to have a special account with State Street
 for the purpose of redeeming Administration Shares from its account by
 check.
 The following general policies govern the check redemption privilege:
 .The Service Organization will be provided with a supply of checks when
  State Street receives a completed signature card and authorization form.
  Checks drawn on the account may be payable to the order of any person in
  any amount over $500, but cannot be certified.
 .The payee of the check may cash or deposit it just like any other check
  drawn on a bank.

 .When the check is presented to State Street for payment, a sufficient num-
  ber of full or fractional Administration Shares will be redeemed to cover
  the amount of the check.
 .Canceled checks will be returned to the Service Organization by State
  Street.
 .The check redemption privilege allows a Service Organization to receive the
  dividends declared on the Administration Shares that are to be redeemed
  until the check is actually processed. Because of this feature, accounts
  may not be completely liquidated by check.
 .If the amount of the check is greater than the value of the Administration
  Shares held in the Service Organization's account, the check will be
  returned unpaid. In this case, the Service Organization may be subject to
  extra charges.
 .The Trust reserves the right to limit the availability of, modify or termi-
  nate the check redemption privilege at any time with respect to any or all
  Service Organizations.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem the Administration Shares of any Service Organization whose account
  balance falls below the minimum as a result of a redemption. The Fund will
  give 60 days' prior written notice to allow a Service Organization to pur-
  chase sufficient additional shares of the Fund in order to avoid such
  redemption.
 .Redeem the shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash)
  from the Fund. If you receive redemption proceeds in-kind, you should
  expect to incur transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Administration Shares of a Fund at NAV
 for shares of the corresponding class of any other Goldman Sachs Fund.
 
                                                                              37

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses, and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.

 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will I Be Sent Regarding Investments In Administration
 Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Upon request, Service
 Organizations will also be provided with a printed confirmation for each
 transaction. Any dividends and distributions paid by the Funds are also
 reflected in regular statements issued by the Funds to Service Organiza-
 tions. Service Organizations are responsible for providing these or other
 reports to their customers who are the beneficial owners of Administration
 Shares in accordance with the rules that apply to their accounts with the
 Service Organizations.

Taxation
 
 
Each Fund intends to qualify as a regulated investment company for federal tax
purposes, and to distribute to shareholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Funds, Fund dividends will generally be taxable to
you as ordinary income (unless your investment is in an IRA or other tax-
advantaged account) regardless of whether you reinvest in additional shares or
take them as cash. The Tax-Exempt Funds expect generally to distribute "exempt-
interest dividends," which will be tax-exempt income for federal income tax
purposes. Moreover, the Tax-Exempt California and Tax-Exempt New York Portfo-
lios expect that their dividends will not be subject to the California and New
York state personal income tax, respectively, (and in the case of the Tax-
Exempt New York Portfolio, New York City personal income tax). The tax status
and amounts of the dividends for each calendar year will be detailed in your
annual tax statement from the Funds.
 
Dividends and distributions from each Fund will generally be taxable to you in
the tax year in which they are paid, with one exception. Dividends and distri-
butions declared by a Fund in October, November or December and paid in January
are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry shares of the
Tax-Exempt Funds generally will not be deductible for income tax purposes.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Funds may be an item of tax preference for purposes of determining
your AMT liability. Exempt-interest dividends will also be considered along
with other adjusted gross income in determining whether any social security or
railroad retirement payments received by you are subject to federal income tax-
es.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from any Fund (including the Tax-Exempt Funds)
or on the value of the shares held by you. More tax information is provided in
the Additional Statement. You should also consult your own tax adviser for
information regarding all tax consequences applicable to your investments in
the Funds.

Appendix A
Additional Information on Portfolio
Risks, Securities and Techniques
 
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Funds, including their associated
risks. Additional information is provided in the Additional Statement, which is
available upon request. Among other things, the Additional Statement describes
certain fundamental policies and investment restrictions that cannot be changed
without shareholder approval. You should note, however, that all policies not
specifically designated as fundamental are non-fundamental and may be changed
without shareholder approval. If there is a change in a Fund's investment
objective, you should consider whether that Fund remains an appropriate invest-
ment in light of your then current financial position and needs.
 
U.S. Treasury Obligations and U.S. Government Securities and Related Custodial
Receipts. U.S. Treasury Obligations include securities issued or issued or
guaranteed by the U.S. Treasury ("U.S. Treasury Obligations"). Payment of
principal and interest on these obligations is backed by the full faith and
credit of the U.S. government. U.S. Treasury Obligations include, among other
things, the separately traded principal and interest components of securities
guaranteed or issued by the U.S. Treasury if such components are traded
independently under the Separate Trading of Registered Interest and Principal
of Securities program ("STRIPS").
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury Obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.
 
                                                                              41

Some Funds invest in U.S. Treasury Obligations and certain U.S. Government
Securities the interest from which is generally exempt from state income taxa-
tion. Securities generally eligible for this exemption include those issued by
the U.S. Treasury and certain agencies, authorities or instrumentalities of the
U.S. government, including the Federal Home Loan Banks, Federal Farm Credit
Banks, Tennessee Valley Authority and Student Loan Marketing Association.
 
U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Certain Funds may also acquire U.S. Government Securities in the form of custo-
dial receipts. Custodial receipts evidence ownership of future interest pay-
ments, principal payments or both on notes or bonds issued or guaranteed as to
principal or interest by the U.S. government, its agencies, instrumentalities,
political subdivisions or authorities. For certain securities law purposes,
custodial receipts are not considered obligations of the U.S. government.
 
Bank Obligations. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. Certain Funds may invest in obligations issued or
backed by U.S. banks when a bank has more than $1 billion in total assets at
the time of purchase or is a branch or subsidiary of such a bank. In addition,
certain Funds may invest in U.S. dollar-denominated obligations issued or
guaranteed by foreign banks that have more than $1 billion in total assets at
the time of purchase, U.S. branches of such foreign banks (Yankee obligations),
foreign branches of such foreign banks and foreign branches of U.S. banks
having more than $1 billion in total assets at the time of purchase. Bank
obligations may be general obligations of the parent bank or may be limited to
the issuing branch by the terms of the specific obligation or by government
regulation.
 
If a Fund invests more than 25% of its total assets in bank obligations
(whether foreign or domestic), it may be especially affected by favorable and
adverse developments in or related to the banking industry. The activities of
U.S. and most foreign banks are subject to comprehensive regulations which, in
the case of U.S. regulations, have undergone substantial changes in the past
decade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of opera-
tions and profitability of domestic and foreign banks. Significant developments
in the U.S. banking industry have included increased competition from other
types of financial institutions, increased acquisition activity and geographic
expansion. Banks may be particularly susceptible to certain economic factors,
such as interest rate changes and adverse developments in the real

                                                                      APPENDIX A
 
estate markets. Fiscal and monetary policy and general economic cycles can
affect the availability and cost of funds, loan demand and asset quality and
thereby impact the earnings and financial conditions of banks.
 
Commercial Paper. A Fund may invest in commercial paper, including variable
amount master demand notes and asset-backed commercial paper. Commercial paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, finance companies and other issuers.
The commercial paper purchased by a Fund consists of direct U.S. dollar-denomi-
nated obligations of domestic or, in the case of certain Funds, foreign
issuers.
 
Short-Term Obligations. A Fund may invest in other short-term obligations,
including short-term funding agreements payable in U.S. dollars and issued or
guaranteed by U.S. corporations, foreign corporations or other entities. A
funding agreement is a contract between an issuer and a purchaser that obli-
gates the issuer to pay a guaranteed rate of interest on a principal sum depos-
ited by the purchaser. Funding agreements will also guarantee a stream of pay-
ments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and guaran-
teed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Fund will be regarded as
illiquid.
 
Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
asset-backed and receivables-backed securities whose principal and interest
payments are collateralized by pools of assets such as auto loans, credit card
receivables, leases, installment contracts and personal property. Asset-backed
and receivables-backed securities are often subject to more rapid repayment
than their stated maturity date would indicate as a result of the pass-through
of prepayments of principal on the underlying loans. During periods of
declining interest rates, prepayment of loans underlying asset-backed and
receivables-backed securities can be expected to accelerate. Accordingly, a
Fund's ability to maintain positions in such securities will be affected by
reductions in the principal amount of such securities resulting from
prepayments, and its ability to reinvest the returns of principal at comparable
yields is subject to generally prevailing interest rates at that time. In
addition, securities that are backed by credit card, automobile and similar
types of receivables generally do not have the benefit of a security interest
in collateral that is comparable in quality to mortgage assets. There is the
possibility that, in some cases, recoveries on repossessed collateral may not
be available to support payments on these securities. In the event of a
default, a Fund may suffer a loss if it cannot sell collateral quickly and
receive the amount it is owed.
 
Foreign Government Obligations and Related Foreign Risks. Certain Funds may
invest in foreign government obligations. Foreign government obligations are
U.S.
 
                                                                              43
<PAGE>
 
 
dollar-denominated obligations (limited to commercial paper and other notes)
issued or guaranteed by a foreign government or other entity located or
organized in a foreign country that maintains a short-term foreign currency
rating in the highest short-term ratings category by the requisite number of
NRSROs.
 
Investments by a Fund in foreign securities, whether issued by a foreign gov-
ernment, bank, corporation or other issuer, may present a greater degree of
risk than investments in securities of domestic issuers because of less public-
ly-available financial and other information, less securities regulation,
potential imposition of foreign withholding and other taxes, war, expropriation
or other adverse governmental actions. Efforts in foreign countries to remedi-
ate potential Year 2000 problems are not as extensive as those in the United
States. As a result, the operations of foreign markets, foreign issuers and
foreign governments may be disrupted by the Year 2000 Problem, and the invest-
ment portfolio of a Fund may be adversely affected. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and generally
are not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks.
 
Repurchase Agreements. Certain Funds may enter into repurchase agreements with
primary dealers in U.S. Government Securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund are less than the repurchase price and the Fund's
cost associated with delay and enforcement of the repurchase agreement. In
addition, in the event of bankruptcy of the seller, a Fund could suffer addi-
tional losses if a court determines that the Fund's interest in the collateral
is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, certain Funds, together with other registered
investment companies having advisory agreements with the Investment Adviser or
any of its affiliates, may transfer uninvested cash balances into a single
joint account, the daily aggregate balance of which will be invested in one or
more repurchase agreements.
 
Municipal Obligations. Certain Funds may invest in municipal obligations.
Municipal obligations are issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies,
authorities and instrumentalities, and the District of Columbia. Municipal
obligations may include fixed rate notes and similar debt instruments; variable
and floating rate demand instruments; tax-exempt commercial paper; municipal
bonds; and unrated notes, paper, bonds or other instruments.

                                                                      APPENDIX A
 
 
Municipal Notes and Bonds. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
Tender Option Bonds. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Fund's average portfolio maturity. There is a risk that a Fund will not be con-
sidered the owner of a tender option bond for federal income tax purposes, and
thus will not be entitled to treat such interest as exempt from federal
income tax. Certain tender option bonds may be illiquid or may become illiquid
as a result of a credit rating downgrade, a payment default or a disqualifica-
tion from tax-exempt status.
 
Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which
 
                                                                              45
<PAGE>
 
 
include a demand feature that permits the holder to sell the RAWs to a bank or
other financial institution at a purchase price equal to par plus accrued
interest on each interest rate reset date.
 
Industrial Development Bonds. Certain Funds may invest in industrial develop-
ment bonds (private activity bonds). Industrial development bonds are a spe-
cific type of revenue bond backed by the credit and security of a private user,
the interest from which would be an item of tax preference when distributed by
a Fund as "exempt-interest dividends" to shareholders under the AMT.
 
Other Municipal Obligation Policies. Certain Funds may invest 25% or more of
the value of their respective total assets in municipal obligations which are
related in such a way that an economic, business or political development or
change affecting one municipal obligation would also affect the other municipal
obligation. For example, a Fund may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of a Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political developments affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality of these banks and financial institutions could,
therefore, cause a loss to a Fund that invests in municipal obligations. Let-
ters of credit and other obligations of foreign banks and financial institu-
tions may involve risks in addition to those of domestic obligations because of
less publicly available financial and other information, less securities regu-
lation, potential imposition of foreign withholding and other taxes, war,
expropriation or other adverse governmental actions. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and are gener-
ally not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks. In addition, the Funds may acquire securities in the
form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.

                                                                      APPENDIX A
 
 
Floating and Variable Rate Obligations. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Fund may consider the maturity of a variable or floating rate obli-
gation to be shorter than its ultimate stated maturity if the obligation is a
U.S. Treasury Obligation or U.S. Government Security, if the obligation has a
remaining maturity of 397 calendar days or less, or if the obligation has a
demand feature that permits the Fund to receive payment at any time or at spec-
ified intervals not exceeding 397 calendar days. The issuers or financial
intermediaries providing demand features may support their ability to purchase
the obligations by obtaining credit with liquidity supports. These may include
lines of credit, which are conditional commitments to lend and letters of cred-
it, which will ordinarily be irrevocable, both of which may be issued by domes-
tic banks or foreign banks which have a branch, agency or subsidiary in the
United States. A Fund may purchase variable or floating rate obligations from
the issuers or may purchase certificates of participation, a type of floating
or variable rate obligation, which are interests in a pool of debt obligations
held by a bank or other financial institution.
 
When-Issued Securities and Forward Commitments. The Funds may purchase when-
issued securities and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. When-issued securities
are securities that have been authorized, but not yet issued. When-issued secu-
rities are purchased in order to secure what is considered to be an advanta-
geous price and yield to a Fund at the time of entering into the transaction. A
forward commitment involves entering into a contract to purchase or sell secu-
rities for a fixed price at a future date beyond the customary settlement peri-
od.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Fund will generally purchase
securities on a when-issued or forward commitment basis with the intention of
acquiring securities for its portfolio, a Fund may dispose of when-issued secu-
rities or forward commitments prior to settlement if the Investment Adviser
deems it appropriate.
 
Other Investment Companies. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Act. These limitations
include a prohibition on any Fund acquiring more than 3% of the voting shares
of any other investment company, and a prohibition on investing more than 5% of
a Fund's total assets in securities of any one investment company or more than
10% of its total assets in securities of all investment companies. A Fund will

ment companies. Such other investment companies will have investment objec-
tives, policies and restrictions substantially similar to those of the acquir-
ing Fund and will be subject to substantially the same risks.
 
Illiquid Securities. Each Fund may invest up to 10% of its net assets in illiq-
uid securities which cannot be disposed of in seven days in the ordinary course
of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
Downgraded Securities. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.
 
Special Risks and Policies Applicable to the Tax-Exempt Funds:
 
Fundamental Policies. As a matter of fundamental policy, at least 80% of each
of the net assets of each of the Tax-Exempt Diversified, Tax-Exempt California
and Tax-Exempt New York Portfolios will ordinarily be invested in municipal
obligations, the interest from which is, in the opinion of bond counsel, if
any, excluded from gross income for federal income tax purposes. In addition,
as a matter of fundamental policy, at least 65% of each of the Tax-Exempt Cali-
fornia and Tax-Exempt New York Portfolio's total assets will be invested in
California and New York municipal obligations, except in extraordinary circum-
stances.
 
For these purposes, California and New York municipal obligations are obliga-
tions issued by or on behalf of the State of California or the State of New
York, respectively, and their respective political subdivisions, agencies and
instrumentalities and the

government of Puerto Rico, the U.S. Virgin Islands and Guam, the interest from
which is excluded from gross income for federal income tax purposes and is
exempt from California State personal income tax or New York State and New York
City personal income tax. Each Tax-Exempt Fund may temporarily invest in tax-
able money market instruments or, in the case of the Tax-Exempt California and
New York Portfolios, in municipal obligations that are not California or New
York municipal obligations, respectively, when acceptable California and New
York municipal obligations are not available or when the Investment Adviser
believes that the market conditions dictate a defensive posture. Investments in
taxable money market instruments will be limited to those meeting the quality
standards of each Tax-Exempt Fund. The Tax-Exempt California and Tax-Exempt New
York Portfolios' distributions of interest from municipal obligations other
than California and New York municipal obligations, respectively, may be sub-
ject to California and New York State and New York City personal income taxes.
 
Risks of Investing in California and New York: The Tax-Exempt California and
Tax-Exempt New York Portfolios concentrate their investments in California and
New York municipal obligations. Consequently, these Funds are more susceptible
to factors adversely affecting issuers of California and New York municipal
obligations, and may be riskier than comparable municipal bond funds and money
market funds that do not emphasize these issuers to this degree.
 
The Tax-Exempt California Portfolio's investments can be affected by political
and economic developments within the State of California (the "State"), and by
the financial condition of the State, its public authorities and political sub-
divisions. After suffering a severe recession in the early 1990's which caused
the State to experience financial difficulties, California's economy entered a
sustained recovery since late 1993 and the State's budget has returned to a
positive balance. California's long-term credit rating has been raised after
being reduced during the recession. To respond to its own revenue shortfalls
during the recession, the State reduced assistance to its public authorities
and political subdivisions. Cutbacks in state aid could further adversely
affect the financial condition of cities, counties and education districts
which are subject to their own fiscal constraints. California voters in the
past have passed amendments to the California Constitution and other measures
that limit the taxing and spending authority of California governmental enti-
ties, and future voter initiatives could result in adverse consequences affect-
ing California municipal obligations. Also, the ultimate fiscal effect of fed-
erally-mandated reform of welfare programs on the State and its local
governments is still to be resolved.
 
These factors, among others (including the outcome of related pending litiga-
tion), could reduce the credit standing of certain issuers of California munic-
ipal obligations. A more detailed discussion of the risks of investing in Cali-
fornia is included in the Additional Statement.
 
                                                                              49

The Tax-Exempt New York Portfolio's investments will be affected by political
and economic developments within the State of New York (the "State"), and by
the financial conditions of the State, its public authorities and political
subdivisions, particularly the City of New York (the "City"). The State and the
City face long-term economic problems that could seriously affect their ability
and that of other issuers of New York municipal obligations to meet their
financial obligations. Certain substantial issuers of New York municipal obli-
gations (including issuers whose obligations may be acquired by the Fund) have
experienced serious financial difficulties in recent years. These difficulties
have at times jeopardized the credit standing and impaired the borrowing abili-
ties of all New York issuers and have generally contributed to higher interest
costs for their borrowings and fewer markets for their outstanding debt obliga-
tions. Although several different issues of municipal obligations of the State
and its agencies and instrumentalities and of the City have been downgraded by
S&P and Moody's in recent years, S&P and Moody's have recently placed the debt
obligations of the State on Credit Watch with positive implications and
upgraded the debt obligations of the City, respectively. Strong demand for New
York municipal obligations has also at times had the effect of permitting New
York municipal obligations to be issued with yields relatively lower, and after
issuance, to trade in the market at prices relatively higher, than comparably
rated municipal obligations issued by other jurisdictions. A recurrence of the
financial difficulties previously experienced by certain issuers of New York
municipal obligations could result in defaults or declines in the market values
of those issuers' existing obligations and, possibly, in the obligations of
other issuers of New York municipal obligations. Although as of April 1, 1999
no issuers were in default with respect to the payment of their New York munic-
ipal obligations, the occurrence of any such default could materially affect
adversely the market values and marketability of all New York municipal obliga-
tions and, consequently, the value of the Fund's holdings. A more detailed dis-
cussion of the risks of investing in New York is included in the Additional
Statement.
 
If California, New York, or any of their local governmental entities are unable
to meet their financial obligations, the corresponding Fund's income, NAV,
ability to preserve or realize appreciation of capital or liquidity could be
adversely affected. Also, neither of these Funds is a diversified fund under
the Act (except to the extent that diversification is required by Rule 2a-7 or
for federal income tax purposes). Because they may invest a larger percentage
of their assets in the securities of fewer issuers than do diversified funds,
these Funds may be exposed to greater risk in that an adverse change in the
condition of one or a small number of issuers would have a greater impact on
them.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Institutional Liquid Assets Portfolios (the "Funds"). GSAM is referred to in
 this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Money Market Funds are managed to seek preservation of capital, daily
 liquidity and maximum current income. With each Fund the Investment Adviser
 follows a conservative, risk-managed investment process that seeks to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 1. Managing Credit Risk
 
 The Investment Adviser's process for managing risk emphasizes:
 .Intensive research--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Funds. Sources for their
  analysis include third-party inputs, such as financial statements and media
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .Timely updates--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 The Result: An "approved" list of high-quality credits--The Investment
 Adviser's portfolio management team uses this approved list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
 
                                                                               1
<PAGE>
 
 2. Managing Interest Rate Risk
 
 Three main steps are followed in seeking to manage interest rate risk:
 .Establish weighted average maturity (WAM) target--WAM (the weighted average
  time until the yield of a portfolio reflects any changes in the current
  interest rate environment) is constantly revisited and adjusted as market
  conditions change. An overall strategy is developed by the portfolio
  management team based on insights gained from weekly meetings with both
  Goldman Sachs economists and economists from outside the firm.
 .Implement optimum portfolio structure--Proprietary models that seek the
  optimum balance of risk and return, in conjunction with the Investment
  Adviser's analysis of factors such as market events, short-term interest
  rates and each Fund's asset volatility, are used to identify the most
  effective portfolio structure.
 .Conduct rigorous analysis of new securities--The Investment Adviser's five-
  step process includes legal, credit, historical index and liquidity
  analysis, as well as price stress testing to determine suitability for
  money market mutual funds.
 
 
 3. Managing Liquidity
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .Each Fund's clients and factors that influence their asset volatility;
 .Technical events that influence the trading range of federal funds and
  other short-term fixed-income markets; and
 .Bid-ask spreads associated with securities in the portfolios.
 
 Benchmarks for the Money Market Funds are the IBC Financial Data Universal
 Averages. Each Fund tracks the IBC Index which best corresponds to the
 Fund's eligible investments.

<PAGE>
 
                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 .The Funds: Each Fund's securities are valued by the amortized cost method as
  permitted by Rule 2a-7 under the Investment Company Act of 1940, as amended
  (the "Act"). Under Rule 2a-7, each Fund may invest only in U.S. dollar-
  denominated securities that are determined to present minimal credit risk
  and meet certain other criteria, including conditions relating to maturity,
  diversification and credit quality. These operating policies may be more
  restrictive than the fundamental policies set forth in the Statement of
  Additional Information (the "Additional Statement").
  .Taxable Funds: Prime Obligations, Money Market, Treasury Obligations and
   Government Portfolios.
  .Tax-Advantaged Funds: Treasury Instruments and Federal Portfolios.
  .Tax-Exempt Funds: Tax-Exempt Diversified, Tax-Exempt California and Tax-
   Exempt New York Portfolios.
 .The Investors: The Funds are designed for investors seeking a high rate of
  return, a stable net asset value ("NAV") and convenient liquidation privi-
  leges. The Funds are particularly suitable for banks, corporations and other
  financial institutions that seek investment of short-term funds for their
  own accounts or for the accounts of their customers.
 .NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
 .Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .Investment Restrictions: Each Fund is subject to certain investment restric-
  tions that are described in detail under "Investment Restrictions" in the
  Additional Statement. Fundamental investment restrictions and the investment
  objective of a Fund (except the Tax-Exempt California and Tax-Exempt New
  York Portfolios' objectives of providing shareholders with income exempt
  from California State and New York State and New York City personal income
  tax, respectively) cannot be changed without approval of a majority of the
  outstanding shares of that Fund. The Treasury Obligations Portfolio's policy
  of limiting its investments to U.S. Treasury Obligations (as defined in
  Appendix A) and related repurchase agreements is also fundamental. All
  investment policies not specifically designated as fundamental are non-fun-
  damental and may be changed without shareholder approval.
 .Diversification: Diversification can help a Fund reduce the risks of invest-
  ing. In accordance with current regulations of the Securities and Exchange
  Commission (the "SEC"), each Fund may not invest more than 5% of the value
  of its total assets at the time of purchase in the securities of any single
  issuer with these exceptions: (a) the Tax-Exempt California and Tax-Exempt
  New York Portfolios may each invest up to 25% of their total assets in five
  or fewer issuers; and (b)
 
                                                                               3
<PAGE>
 
  each of the other Funds may invest up to 25% of its total assets in the
  securities of a single issuer for up to three business days. These limita-
  tions do not apply to cash, certain repurchase agreements, U.S. Government
  Securities (as defined in Appendix A) or securities of other investment com-
  panies. In addition, securities subject to certain unconditional guarantees
  and securities that are not "First Tier Securities" as defined by the SEC
  are subject to different diversification requirements as described in the
  Additional Statement.

Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Treasury Obligations, Treasury Instru-
 ments, Government and Federal Portfolios seek to maximize current income to
 the extent consistent with the preservation of capital and the maintenance
 of liquidity by investing exclusively in high quality money market instru-
 ments.
 
 The Prime Obligations and Money Market Portfolios pursue their investment
 objectives by investing in U.S. Government Securities, obligations of U.S.
 banks, commercial paper and other short-term obligations of U.S. companies,
 states, municipalities and other entities and repurchase agreements. The
 Money Market Portfolio may also invest in U.S. dollar-denominated obliga-
 tions of foreign banks, foreign companies and foreign governments.
 
 The Treasury Obligations Portfolio pursues its investment objective by
 investing in securities issued or guaranteed by the U.S. Treasury and repur-
 chase agreements relating to such securities. The Government Portfolio pur-
 sues its investment objective by investing in U.S. Government Securities and
 repurchase agreements relating to such securities.
 
 The Treasury Instruments and Federal Portfolios pursue their investment
 objectives by limiting their investments to certain U.S. Treasury Obliga-
 tions and U.S. Government Securities, respectively, the interest from which
 is generally exempt from state income taxation. You should consult your tax
 adviser to determine whether distributions from the Treasury Instruments and
 Federal Portfolios (and any other Fund that may hold such obligations)
 derived from interest on such obligations are exempt from state income taxa-
 tion in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
 Portfolios seek to provide shareholders, to the extent consistent with the
 preservation of capital and prescribed portfolio standards, with a high
 level of income exempt from federal income tax by investing primarily in
 municipal instruments.
 
 In addition, the Tax-Exempt California and Tax-Exempt New York Portfolios
 seek to provide shareholders with income exempt from California State and
 New York State and City personal income taxes, respectively.
 
 The Tax-Exempt Funds pursue their investment objectives by investing in
 securities issued by or on behalf of states, territories, and possessions of
 the United States and their political subdivisions, agencies, authorities
 and instrumentalities, and the District of Columbia, the interest from
 which, if any, is in the opinion of bond counsel excluded from gross income
 for federal income tax purposes, and not an item of tax preference under the
 federal alternative minimum tax ("AMT").
 
                                                                               5

 6 Will only make such investments when yields on such securities are
   attractive compared to other taxable investments.
 7 Ordinarily expect that 100% of a Fund's portfolio securities will be
   invested in municipal obligations, but the Funds may, for temporary
   defensive purposes, hold cash or invest in short-term taxable securities.
 8 To the extent permitted by Rule 2a-7, securities without short-term ratings
   may be purchased if they are deemed to be of comparable quality to First
   Tier Securities, or to the extent that a Fund may purchase Second Tier
   Securities, comparable in quality to Second Tier Securities. In addition, a
   Fund holding a security supported by a guarantee or demand feature may rely
   on the credit quality of the guarantee or demand feature in determining the
   credit quality of the investment.
 9 If such policy should change, private activity bonds subject to AMT would
   not exceed 20% of a Fund's net assets under normal market conditions.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

Risks that apply to all Funds:
 
 .NAV Risk--The risk that a Fund will not be able to maintain a NAV per share of
 $1.00 at all times.
 .Interest Rate Risk--The risk that during periods of rising interest rates, a
 Fund's yield (and the market value of its securities) will tend to be lower
 than prevailing market rates; in periods of falling interest rates, a Fund's
 yield will tend to be higher.
 .Credit/Default Risk--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York Portfo-
 lios, risk of loss from payment default may also exist where municipal instru-
 ments are backed by foreign letters of credit or guarantees.
 .Liquidity Risk--The risk that a Fund will be unable to pay redemption proceeds
 within the time period stated in this Prospectus, because of unusual market
 conditions, an unusually high volume of redemption requests, or other reasons.
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Risk that applies to the Prime Obligations, Money Market, Government and
Federal Portfolios:
 
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market Portfolio:
 
 .Foreign Risk--The risk that a foreign security could lose value as a result of
 political, financial and economic events in foreign countries, less publicly
 available financial and other information, less stringent foreign securities
 regulations and accounting and disclosure standards, or other factors. The
 Money Market Portfolio may not invest more than 25% of its total assets in the
 securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
 .Banking Industry Risk--The risk that if the Fund invests more than 25% of its
 total assets in bank obligations, an adverse development in the banking indus-
 try may affect the value of the Fund's investments more than if the Fund's
 investments were not invested to such a degree in the banking industry. Nor-
 mally, the Money Market Portfolio intends to invest more than 25% of its total
 assets in bank obligations. Banks may be particularly susceptible to certain
 economic factors such as interest rate changes, adverse developments in the
 real estate market, fiscal and monetary policy and general economic cycles.
 
Risks that apply to the Tax-Exempt Funds:
 
 .Concentration Risk--The risk that if a Fund invests more than 25% of its total
 assets in issuers within the same state, industry or economic sector, an
 adverse economic, business or political development may affect the value of
 the Fund's investments more than if its investments were not so concentrated.
 The Tax-Exempt California and Tax-Exempt New York Portfolios intend to invest
 at least 65% of their total assets in California municipal obligations and New
 York municipal obligations, respectively. These two Funds are classified as
 "non-diversified" for regulatory purposes.
 .Tax Risk--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of a Fund to pay federal tax-
 exempt dividends (in the case of each of these Funds) and state tax-exempt
 dividends (in the case of the Tax-Exempt California and Tax-Exempt New York
 Portfolios).
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Service
 Shares from year to year; and (b) the average annual returns of a Fund's
 Service Shares. Investors should be aware that the fluctuation of interest
 rates is one primary factor in performance volatility. The bar chart and
 table assume reinvestment of dividends and distributions. A Fund's past per-
 formance is not necessarily an indication of how the Fund will perform in
 the future. Performance reflects expense limitations in effect. If expense
 limitations were not in place, a Fund's performance would have been reduced.
 You may obtain a Fund's current yield by calling 1-800-621-2550.

1The Funds' annual operating expenses are based on actual expenses.
2Service Organizations may charge other fees directly to their customers who
are the beneficial owners of Service Shares in connection with their customers'
accounts. Such fees may affect the return such customers realize with respect
to their investments.
3"Other Expenses" include transfer agency fees equal to 0.04% of the average
daily net assets of each Fund's Service Shares plus all other ordinary expenses
not detailed above.
4The Investment Adviser has voluntarily agreed to reduce or limit "Total Fund
Operating Expenses" of each Fund (excluding service fees, taxes, interest,
brokerage fees, litigation, indemnification and other extraordinary expenses)
to 0.43% of each Fund's average daily net assets. As a result of the current
expense limitations, "Other Expenses" and "Total Fund Operating Expenses" of
the Funds which are actually incurred are as set forth below. The expense
limitations may be terminated at any time at the option of the Investment
Adviser with the approval of the Trustees. If this occurs, "Other Expenses" and
"Total Fund Operating Expenses" may increase without shareholder approval.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the expense limitations) with the cost of investing in other
mutual funds. The Example assumes that you invest $10,000 in Service Shares of
a Fund for the time periods indicated and then redeem all of your shares at the
end of those periods. The Example also assumes that your investment has a 5%
return each year and that a Fund's operating expenses remain the same. Although
your actual costs may be higher or lower, based on these assumptions your costs
would be:

Service Organizations that invest in Service Shares on behalf of their custom-
ers may charge other fees directly to their customer accounts in connection
with their investments. You should contact your Service Organization for infor-
mation regarding such charges. Such fees, if any, may affect the return such
customers realize with respect to their investment.
 
Certain Service Organizations may receive other compensation in connection with
the sale and distribution of Service Shares or for services to their customers'
accounts and/or the Funds. For additional information regarding such compensa-
tion, see "Shareholder Guide" in the Prospectus and "Other Information" in the
Additional Statement.

Service Providers
 
 INVESTMENT ADVISER
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. The Goldman Sachs Group,
 L.P., which controls the Investment Adviser, announced that it will pursue
 an initial public offering of the firm in the late spring or early summer of
 1999. Simultaneously with the offering, the Goldman Sachs Group, L.P. will
 merge into The Goldman Sachs Group, Inc. As of February 28, 1999, GSAM,
 together with its affiliates, acted as investment adviser or distributor for
 assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
 .Continually manages each Fund, including the purchase, retention and
  disposition of securities and other assets
 .Administers each Fund's business affairs
 .Performs various recordholder servicing functions (to the extent not
  provided by other organizations)
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter
 into principal transactions in certain taxable money market instruments,
 including repurchase agreements, with Goldman Sachs.
 
 MANAGEMENT FEES
 
 As compensation for its services and its assumption of certain expenses, the
 Investment Adviser is entitled to the following fees, computed daily and
 payable monthly, at the annual rates listed below:

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.

 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000
 preparedness of the issuers of securities held by the Funds. The Investment
 Adviser may obtain such Year 2000 information from various sources which the
 Investment Adviser believes to be reliable, including the issuers' public
 regulatory filings. However, the Investment Adviser is not in a position to
 verify the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
                                                                              29

Dividends
 
 
 All or substantially all of each Fund's net investment income will be
 declared as a dividend daily. Dividends will normally, but not always, be
 declared as of 4:00 p.m. New York time as a dividend and distributed to
 shareholders monthly. You may choose to have dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 
 You may indicate your election on your Account Application. Any changes may
 be submitted in writing to Goldman Sachs at any time. If you do not indicate
 any choice, your dividends and distributions will be reinvested automati-
 cally in the applicable Fund.
 
 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and December may be distributed during the
 subsequent calendar year. Although realized gains and losses on the assets
 of a Fund are reflected in the NAV of the Fund, they are not expected to be
 of an amount which would affect the Fund's NAV of $1.00 per share.

Shareholder Guide
 
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Service
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Service Shares Of The Funds?
 Generally, Service Shares may be purchased only through institutions that
 have agreed to provide account administration and personal and account main-
 tenance services to their customers who are the beneficial owners of Service
 Shares. These institutions are called "Service Organizations." Customers of
 a Service Organization will normally give their purchase instructions to the
 Service Organization, and the Service Organization will, in turn, place pur-
 chase orders with Goldman Sachs. Service Organizations will set times by
 which purchase orders and payments must be received by them from their cus-
 tomers. Generally, Service Shares may be purchased from the Funds on any
 business day at their NAV next determined after receipt of an order by
 Goldman Sachs from a Service Organization. Shares begin earning dividends
 after the Fund's receipt of the purchase amount in federal funds. No sales
 load is charged.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place a purchase order in writing or by telephone.

 Before or immediately after placing an initial purchase order, a Service
 Organization should complete and send to Goldman Sachs the Account Applica-
 tion attached to this Prospectus.
 
                                                                              31

 Service Organizations may send their payments as follows:
 .Wire federal funds to The Northern Trust Company ("Northern"), as sub-
  custodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); or
 .Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds -
   (Name of Fund and Class of Shares), 4900 Sears Tower - 60th Floor, Chica-
  go, IL 60606-6372. The Funds will not accept a check drawn on a foreign
  bank or a third-party check.
 
 It is strongly recommended that payment be effected by wiring federal funds
 to Northern.
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.
 
 When Do Shares Begin Earning Dividends?
 Dividends begin to accrue as follows:

 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Service Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 .Responding to inquiries from prospective and existing shareholders
 .Assisting customers with investment procedures
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on

 behalf of their customers, and may designate other intermediaries to accept
 such orders, if approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to a service plan adopted by the Trust's Board of Trustees, Service
 Organizations are entitled to receive payment for their services from the
 Trust of up to 0.40% (on an annualized basis) of the average daily net
 assets of the Service Shares of the Funds, which are attributable to or held
 in the name of the Service Organization for its customers. In addition,
 GSAM, at its own expense, may pay a Service Organization up to 0.10% of the
 average daily net assets of the Service Shares of the Fund, which are
 attributable to or held in the name of the Service Organization for its cus-
 tomers. Such compensation does not represent an additional expense to a Fund
 or its shareholders, since it will be paid from the assets of GSAM.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses.
 
 In addition to Service Shares, each Fund also offers other classes of shares
 to investors. These other share classes are subject to different fees and
 expenses (which affect performance), have different minimum investment
 requirements and are entitled to different services than Service Shares.
 Information regarding these other share classes may be obtained from your
 sales representative or from Goldman Sachs by calling the number on the back
 cover of this Prospectus.
 
                                                                              33

 What Is My Minimum Investment In The Funds?
 The Funds do not have any minimum purchase or account requirements with
 respect to Service Shares. A Service Organization may, however, impose a
 minimum amount for initial and subsequent investments in Service Shares, and
 may establish other requirements such as a minimum account balance. A Serv-
 ice Organization may redeem Service Shares held by non-complying accounts,
 and may impose a charge for any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment and minimum account balance require-
  ment.
 .Reject any purchase order for any reason.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Service Shares
 is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will be priced on any day the
  New York Stock Exchange is open, except for days on which Chicago, Boston
  or New York banks are closed for local holidays.
 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.

 HOW TO SELL SHARES
 
 
 How Can I Sell Service Shares Of The Funds?
 Generally, Service Shares may be sold (redeemed) only through Service Orga-
 nizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. Generally,
 each Fund will redeem Service Shares upon request on any business day at
 their NAV next determined after receipt of such request in proper form. A
 Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is elected on the Account Appli-
 cation.

 Certain Service Organizations are authorized to accept redemption requests
 on behalf of the Funds as described under "What Do I Need To Know About
 Service Organizations?" A redemption may also be made with respect to cer-
 tain Funds by means of the check redemption privilege.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
                                                                              35

 When Will Redemption Proceeds Be Wired?
 Redemption proceeds will normally be wired to the bank account designated on
 a Service Organization's Account Application as follows:

 --------------------------------------------------------------------------------
</TABLE>
 
 .Although redemption proceeds will normally be wired as described above,
  each Fund reserves the right to pay redemption proceeds up to three busi-
  ness days following receipt of a properly executed wire transfer redemption
  request. If you are selling shares you recently paid for by check, the Fund
  will pay you when your check has cleared, which may take up to 15 days. If
  the Federal Reserve Bank is closed on the day that the redemption proceeds
  would ordinarily be wired, wiring the redemption proceeds may be delayed
  one additional business day.
 .Neither the Trust nor Goldman Sachs assumes any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organizations.
 
 What Should I Know About The Check Redemption Privilege?
 A Service Organization may elect to have a special account with State Street
 for the purpose of redeeming Service Shares from its account by check.
 The following general policies govern the check redemption privilege:
 .The Service Organization will be provided with a supply of checks when
  State Street receives a completed signature card and authorization form.
  Checks drawn on the account may be payable to the order of any person in
  any amount over $500, but cannot be certified.

                                                               SHAREHOLDER GUIDE
 
 .The payee of the check may cash or deposit it just like any other check
  drawn on a bank.
 .When the check is presented to State Street for payment, a sufficient num-
  ber of full or fractional Service Shares will be redeemed to cover the
  amount of the check.
 .Canceled checks will be returned to the Service Organization by State
  Street.
 .The check redemption privilege allows a Service Organization to receive the
  dividends declared on the Service Shares that are to be redeemed until the
  check is actually processed. Because of this feature, accounts may not be
  completely liquidated by check.
 .If the amount of the check is greater than the value of the Service Shares
  held in the Service Organization's account, the check will be returned
  unpaid. In this case, the Service Organization may be subject to extra
  charges.
 .The Trust reserves the right to limit the availability of, modify or termi-
  nate the check redemption privilege at any time with respect to any or all
  Service Organizations.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem the Service Shares of any Service Organization whose account balance
  falls below the minimum as a result of a redemption. The Fund will give 60
  days' prior written notice to allow a Service Organization to purchase suf-
  ficient additional shares of the Fund in order to avoid such redemption.
 .Redeem the shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
                                                                              37

 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Service Shares of a Fund at NAV for
 shares of the corresponding class of any other Goldman Sachs Fund. The
 exchange privilege may be materially modified or withdrawn at any time upon
 60 days' written notice.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirement of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.

 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will I Be Sent Regarding Investments In Service
 Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Upon request, Service
 Organizations will also be provided with a printed confirmation for each
 transaction. Any dividends and distributions paid by the Funds are also
 reflected in regular statements issued by the Funds to Service Organiza-
 tions. Service Organizations are responsible for providing these or other
 reports to their customers who are the beneficial owners of Service Shares
 in accordance with the rules that apply to their accounts with the Service
 Organizations.
 
                                                                              39
<PAGE>
 
Taxation
 
 
Each Fund intends to qualify as a regulated investment company for federal tax
purposes, and to distribute to shareholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Funds, Fund dividends will generally be taxable to
you as ordinary income (unless your investment is in an IRA or other tax-
advantaged account) regardless of whether you reinvest in additional shares or
take them as cash. The Tax-Exempt Funds expect generally to distribute "exempt-
interest dividends," which will be tax-exempt income for federal income tax
purposes. Moreover, the Tax-Exempt California and Tax-Exempt New York Portfo-
lios expect that their dividends will not be subject to the California and New
York state personal income tax, respectively, (and in the case of the Tax-
Exempt New York Portfolio, New York City personal income tax). The tax status
and amounts of the dividends for each calendar year will be detailed in your
annual tax statement from the Funds.
 
Dividends and distributions from each Fund will generally be taxable to you in
the tax year in which they are paid, with one exception. Dividends and distri-
butions declared by a Fund in October, November or December and paid in January
are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry shares of the
Tax-Exempt Funds generally will not be deductible for income tax purposes.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Funds may be an item of tax preference for purposes of determining
your AMT liability. Exempt-interest dividends will also be considered along
with other adjusted gross income in determining whether any social security or
railroad retirement payments received by you are subject to federal income tax-
es.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from any Fund (including the Tax-Exempt Funds)
or on the value of the shares held by you. More tax information is provided in
the Additional Statement. You should also consult your own tax adviser for
information regarding all tax consequences applicable to your investments in
the Funds.

Appendix A
Additional Information on Portfolio
Risks, Securities and Techniques
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Funds, including their associated
risks. Additional information is provided in the Additional Statement, which is
available upon request. Among other things, the Additional Statement describes
certain fundamental policies and investment restrictions that cannot be changed
without shareholder approval. You should note, however, that all policies not
specifically designated as fundamental are non-fundamental and may be changed
without shareholder approval. If there is a change in a Fund's investment
objective, you should consider whether that Fund remains an appropriate invest-
ment in light of your then current financial position and needs.
 
U.S. Treasury Obligations and U.S. Government Securities and Related Custodial
Receipts. U.S. Treasury Obligations include securities issued or issued or
guaranteed by the U.S. Treasury ("U.S. Treasury Obligations"). Payment of
principal and interest on these obligations is backed by the full faith and
credit of the U.S. government. U.S. Treasury Obligations include, among other
things, the separately traded principal and interest components of securities
guaranteed or issued by the U.S. Treasury if such components are traded
independently under the Separate Trading of Registered Interest and Principal
of Securities program ("STRIPS").
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury Obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.
 
                                                                              41

Some Funds invest in U.S. Treasury Obligations and certain U.S. Government
Securities the interest from which is generally exempt from state income taxa-
tion. Securities generally eligible for this exemption include those issued by
the U.S. Treasury and certain agencies, authorities or instrumentalities of the
U.S. government, including the Federal Home Loan Banks, Federal Farm Credit
Banks, Tennessee Valley Authority and Student Loan Marketing Association.
 
U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Certain Funds may also acquire U.S. Government Securities in the form of custo-
dial receipts. Custodial receipts evidence ownership of future interest pay-
ments, principal payments or both on notes or bonds issued or guaranteed as to
principal or interest by the U.S. government, its agencies, instrumentalities,
political subdivisions or authorities. For certain securities law purposes,
custodial receipts are not considered obligations of the U.S. government.
 
Bank Obligations. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. Certain Funds may invest in obligations issued or
backed by U.S. banks when a bank has more than $1 billion in total assets at
the time of purchase or is a branch or subsidiary of such a bank. In addition,
certain Funds may invest in U.S. dollar-denominated obligations issued or
guaranteed by foreign banks that have more than $1 billion in total assets at
the time of purchase, U.S. branches of such foreign banks (Yankee obligations),
foreign branches of such foreign banks and foreign branches of U.S. banks
having more than $1 billion in total assets at the time of purchase. Bank
obligations may be general obligations of the parent bank or may be limited to
the issuing branch by the terms of the specific obligation or by government
regulation.
 
If a Fund invests more than 25% of its total assets in bank obligations
(whether foreign or domestic), it may be especially affected by favorable and
adverse developments in or related to the banking industry. The activities of
U.S. and most foreign banks are subject to comprehensive regulations which, in
the case of U.S. regulations, have undergone substantial changes in the past
decade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of opera-
tions and profitability of domestic and foreign banks. Significant developments
in the U.S. banking industry have included increased competition from other
types of financial institutions, increased acquisition activity and geographic
expansion. Banks may be particularly susceptible to certain economic factors,
such as interest rate changes and adverse developments in the real

estate markets. Fiscal and monetary policy and general economic cycles can
affect the availability and cost of funds, loan demand and asset quality and
thereby impact the earnings and financial conditions of banks.
 
Commercial Paper. A Fund may invest in commercial paper, including variable
amount master demand notes and asset-backed commercial paper. Commercial paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, finance companies and other issuers.
The commercial paper purchased by a Fund consists of direct U.S. dollar-denomi-
nated obligations of domestic or, in the case of certain Funds, foreign
issuers.
 
Short-Term Obligations. A Fund may invest in other short-term obligations,
including short-term funding agreements payable in U.S. dollars and issued or
guaranteed by U.S. corporations, foreign corporations or other entities. A
funding agreement is a contract between an issuer and a purchaser that obli-
gates the issuer to pay a guaranteed rate of interest on a principal sum depos-
ited by the purchaser. Funding agreements will also guarantee a stream of pay-
ments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and guaran-
teed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Fund will be regarded as
illiquid.
 
Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
asset-backed and receivables-backed securities whose principal and interest
payments are collateralized by pools of assets such as auto loans, credit card
receivables, leases, installment contracts and personal property. Asset-backed
and receivables-backed securities are often subject to more rapid repayment
than their stated maturity date would indicate as a result of the pass-through
of prepayments of principal on the underlying loans. During periods of
declining interest rates, prepayment of loans underlying asset-backed and
receivables-backed securities can be expected to accelerate. Accordingly, a
Fund's ability to maintain positions in such securities will be affected by
reductions in the principal amount of such securities resulting from
prepayments, and its ability to reinvest the returns of principal at comparable
yields is subject to generally prevailing interest rates at that time. In
addition, securities that are backed by credit card, automobile and similar
types of receivables generally do not have the benefit of a security interest
in collateral that is comparable in quality to mortgage assets. There is the
possibility that, in some cases, recoveries on repossessed collateral may not
be available to support payments on these securities. In the event of a
default, a Fund may suffer a loss if it cannot sell collateral quickly and
receive the amount it is owed.
 
Foreign Government Obligations and Related Foreign Risks. Certain Funds may
invest in foreign government obligations. Foreign government obligations are
U.S.
 
                                                                              43

dollar-denominated obligations (limited to commercial paper and other notes)
issued or guaranteed by a foreign government or other entity located or
organized in a foreign country that maintains a short-term foreign currency
rating in the highest short-term ratings category by the requisite number of
NRSROs.
 
Investments by a Fund in foreign securities, whether issued by a foreign gov-
ernment, bank, corporation or other issuer, may present a greater degree of
risk than investments in securities of domestic issuers because of less public-
ly-available financial and other information, less securities regulation,
potential imposition of foreign withholding and other taxes, war, expropriation
or other adverse governmental actions. Efforts in foreign countries to remedi-
ate potential Year 2000 problems are not as extensive as those in the United
States. As a result, the operations of foreign markets, foreign issuers and
foreign governments may be disrupted by the Year 2000 Problem, and the invest-
ment portfolio of a Fund may be adversely affected. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and generally
are not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks.
 
Repurchase Agreements. Certain Funds may enter into repurchase agreements with
primary dealers in U.S. Government Securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund are less than the repurchase price and the Fund's
cost associated with delay and enforcement of the repurchase agreement. In
addition, in the event of bankruptcy of the seller, a Fund could suffer addi-
tional losses if a court determines that the Fund's interest in the collateral
is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, certain Funds, together with other registered
investment companies having advisory agreements with the Investment Adviser or
any of its affiliates, may transfer uninvested cash balances into a single
joint account, the daily aggregate balance of which will be invested in one or
more repurchase agreements.
 
Municipal Obligations. Certain Funds may invest in municipal obligations.
Municipal obligations are issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies,
authorities and instrumentalities, and the District of Columbia. Municipal
obligations may include fixed rate notes and similar debt instruments; variable
and floating rate demand instruments; tax-exempt commercial paper; municipal
bonds; and unrated notes, paper, bonds or other instruments.

Municipal Notes and Bonds. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
Tender Option Bonds. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Fund's average portfolio maturity. There is a risk that a Fund will not be con-
sidered the owner of a tender option bond for federal income tax purposes, and
thus will not be entitled to treat such interest as exempt from federal
income tax. Certain tender option bonds may be illiquid or may become illiquid
as a result of a credit rating downgrade, a payment default or a disqualifica-
tion from tax-exempt status.
 
Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which
 
                                                                              45
<PAGE>
 
 
include a demand feature that permits the holder to sell the RAWs to a bank or
other financial institution at a purchase price equal to par plus accrued
interest on each interest rate reset date.
 
Industrial Development Bonds. Certain Funds may invest in industrial develop-
ment bonds (private activity bonds). Industrial development bonds are a spe-
cific type of revenue bond backed by the credit and security of a private user,
the interest from which would be an item of tax preference when distributed by
a Fund as "exempt-interest dividends" to shareholders under the AMT.
 
Other Municipal Obligation Policies. Certain Funds may invest 25% or more of
the value of their respective total assets in municipal obligations which are
related in such a way that an economic, business or political development or
change affecting one municipal obligation would also affect the other municipal
obligation. For example, a Fund may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of a Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political developments affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality of these banks and financial institutions could,
therefore, cause a loss to a Fund that invests in municipal obligations. Let-
ters of credit and other obligations of foreign banks and financial institu-
tions may involve risks in addition to those of domestic obligations because of
less publicly available financial and other information, less securities regu-
lation, potential imposition of foreign withholding and other taxes, war,
expropriation or other adverse governmental actions. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and are gener-
ally not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks. In addition, the Funds may acquire securities in the
form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.

Floating and Variable Rate Obligations. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Fund may consider the maturity of a variable or floating rate obli-
gation to be shorter than its ultimate stated maturity if the obligation is a
U.S. Treasury Obligation or U.S. Government Security, if the obligation has a
remaining maturity of 397 calendar days or less, or if the obligation has a
demand feature that permits the Fund to receive payment at any time or at spec-
ified intervals not exceeding 397 calendar days. The issuers or financial
intermediaries providing demand features may support their ability to purchase
the obligations by obtaining credit with liquidity supports. These may include
lines of credit, which are conditional commitments to lend and letters of cred-
it, which will ordinarily be irrevocable, both of which may be issued by domes-
tic banks or foreign banks which have a branch, agency or subsidiary in the
United States. A Fund may purchase variable or floating rate obligations from
the issuers or may purchase certificates of participation, a type of floating
or variable rate obligation, which are interests in a pool of debt obligations
held by a bank or other financial institution.
 
When-Issued Securities and Forward Commitments. The Funds may purchase when-
issued securities and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. When-issued securities
are securities that have been authorized, but not yet issued. When-issued secu-
rities are purchased in order to secure what is considered to be an advanta-
geous price and yield to a Fund at the time of entering into the transaction. A
forward commitment involves entering into a contract to purchase or sell secu-
rities for a fixed price at a future date beyond the customary settlement peri-
od.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Fund will generally purchase
securities on a when-issued or forward commitment basis with the intention of
acquiring securities for its portfolio, a Fund may dispose of when-issued secu-
rities or forward commitments prior to settlement if the Investment Adviser
deems it appropriate.
 
Other Investment Companies. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Act. These limitations
include a prohibition on any Fund acquiring more than 3% of the voting shares
of any other investment company, and a prohibition on investing more than 5% of
a Fund's total assets in securities of any one investment company or more than
10% of its total
 
                                                                              47
<PAGE>
 
 
assets in securities of all investment companies. A Fund will indirectly bear
its proportionate share of any management fees and other expenses paid by such
other investment companies. Such other investment companies will have invest-
ment objectives, policies and restrictions substantially similar to those of
the acquiring Fund and will be subject to substantially the same risks.
 
Illiquid Securities. Each Fund may invest up to 10% of its net assets in illiq-
uid securities which cannot be disposed of in seven days in the ordinary course
of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
Downgraded Securities. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.
 
Special Risks and Policies Applicable to the Tax-Exempt Funds:
 
Fundamental Policies. As a matter of fundamental policy, at least 80% of each
of the net assets of each of the Tax-Exempt Diversified, Tax-Exempt California
and Tax-Exempt New York Portfolios will ordinarily be invested in municipal
obligations, the interest from which is, in the opinion of bond counsel, if
any, excluded from gross income for federal income tax purposes. In addition,
as a matter of fundamental policy, at least 65% of each of the Tax-Exempt Cali-
fornia and Tax-Exempt New York Portfolio's total assets will be invested in
California and New York municipal obligations, except in extraordinary circum-
stances.
 
For these purposes, California and New York municipal obligations are obliga-
tions issued by or on behalf of the State of California or the State of New
York, respectively, and their respective political subdivisions, agencies and
instrumentalities and the government of Puerto Rico, the U.S. Virgin Islands
and Guam, the interest from

                                                                      APPENDIX A
 
which is excluded from gross income for federal income tax purposes and is
exempt from California State personal income tax or New York State and New York
City personal income tax. Each Tax-Exempt Fund may temporarily invest in tax-
able money market instruments or, in the case of the Tax-Exempt California and
New York Portfolios, in municipal obligations that are not California or New
York municipal obligations, respectively, when acceptable California and New
York municipal obligations are not available or when the Investment Adviser
believes that the market conditions dictate a defensive posture. Investments in
taxable money market instruments will be limited to those meeting the quality
standards of each Tax-Exempt Fund. The Tax-Exempt California and Tax-Exempt New
York Portfolios' distributions of interest from municipal obligations other
than California and New York municipal obligations, respectively, may be sub-
ject to California and New York State and New York City personal income taxes.
 
Risks of Investing in California and New York: The Tax-Exempt California and
Tax-Exempt New York Portfolios concentrate their investments in California and
New York municipal obligations. Consequently, these Funds are more susceptible
to factors adversely affecting issuers of California and New York municipal
obligations, and may be riskier than comparable municipal bond funds and money
market funds that do not emphasize these issuers to this degree.
 
The Tax-Exempt California Portfolio's investments can be affected by political
and economic developments within the State of California (the "State"), and by
the financial condition of the State, its public authorities and political sub-
divisions. After suffering a severe recession in the early 1990's which caused
the State to experience financial difficulties, California's economy entered a
sustained recovery since late 1993 and the State's budget has returned to a
positive balance. California's long-term credit rating has been raised after
being reduced during the recession. To respond to its own revenue shortfalls
during the recession, the State reduced assistance to its public authorities
and political subdivisions. Cutbacks in state aid could further adversely
affect the financial condition of cities, counties and education districts
which are subject to their own fiscal constraints. California voters in the
past have passed amendments to the California Constitution and other measures
that limit the taxing and spending authority of California governmental enti-
ties, and future voter initiatives could result in adverse consequences affect-
ing California municipal obligations. Also, the ultimate fiscal effect of fed-
erally-mandated reform of welfare programs on the State and its local
governments is still to be resolved.
 
These factors, among others (including the outcome of related pending litiga-
tion), could reduce the credit standing of certain issuers of California munic-
ipal obligations. A more detailed discussion of the risks of investing in Cali-
fornia is included in the Additional Statement.
 
                                                                              49
<PAGE>
 
 
 
The Tax-Exempt New York Portfolio's investments will be affected by political
and economic developments within the State of New York (the "State"), and by
the financial conditions of the State, its public authorities and political
subdivisions, particularly the City of New York (the "City"). The State and the
City face long-term economic problems that could seriously affect their ability
and that of other issuers of New York municipal obligations to meet their
financial obligations. Certain substantial issuers of New York municipal obli-
gations (including issuers whose obligations may be acquired by the Fund) have
experienced serious financial difficulties in recent years. These difficulties
have at times jeopardized the credit standing and impaired the borrowing abili-
ties of all New York issuers and have generally contributed to higher interest
costs for their borrowings and fewer markets for their outstanding debt obliga-
tions. Although several different issues of municipal obligations of the State
and its agencies and instrumentalities and of the City have been downgraded by
S&P and Moody's in recent years, S&P and Moody's have recently placed the debt
obligations of the State on Credit Watch with positive implications and
upgraded the debt obligations of the City, respectively. Strong demand for New
York municipal obligations has also at times had the effect of permitting New
York municipal obligations to be issued with yields relatively lower, and after
issuance, to trade in the market at prices relatively higher, than comparably
rated municipal obligations issued by other jurisdictions. A recurrence of the
financial difficulties previously experienced by certain issuers of New York
municipal obligations could result in defaults or declines in the market values
of those issuers' existing obligations and, possibly, in the obligations of
other issuers of New York municipal obligations. Although as of April 1, 1999
no issuers were in default with respect to the payment of their New York munic-
ipal obligations, the occurrence of any such default could materially affect
adversely the market values and marketability of all New York municipal obliga-
tions and, consequently, the value of the Fund's holdings. A more detailed dis-
cussion of the risks of investing in New York is included in the Additional
Statement.
 
If California, New York, or any of their local governmental entities are unable
to meet their financial obligations, the corresponding Fund's income, NAV,
ability to preserve or realize appreciation of capital or liquidity could be
adversely affected. Also, neither of these Funds is a diversified fund under
the Act (except to the extent that diversification is required by Rule 2a-7 or
for federal income tax purposes). Because they may invest a larger percentage
of their assets in the securities of fewer issuers than do diversified funds,
these Funds may be exposed to greater risk in that an adverse change in the
condition of one or a small number of issuers would have a greater impact on
them.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Institutional Liquid Assets Portfolios (the "Funds"). GSAM is referred to in
 this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Money Market Funds are managed to seek preservation of capital, daily
 liquidity and maximum current income. With each Fund the Investment Adviser
 follows a conservative, risk-managed investment process that seeks to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 Investment Process
 
 1.Managing Credit Risk
 
 The Investment Adviser's process for managing risk emphasizes:
 .Intensive research--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Funds. Sources for their
  analysis include third-party inputs, such as financial statements and media
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .Timely updates--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 The Result: An "approved" list of high-quality credits--The Investment
 Adviser's portfolio management team uses this approved list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
                                                                               1
<PAGE>
 
 
 2.Managing Interest Rate Risk
 Three main steps are followed in seeking to manage interest rate risk:
 .  Establish weighted average maturity (WAM) target--WAM (the weighted
    average time until the yield of a portfolio reflects any changes in the
    current interest rate environment) is constantly revisited and adjusted
    as market conditions change. An overall strategy is developed by the
    portfolio management team based on insights gained from weekly meetings
    with both Goldman Sachs economists and economists from outside the firm.
 .  Implement optimum portfolio structure--Proprietary models that seek the
    optimum balance of risk and return, in conjunction with the Investment
    Adviser's analysis of factors such as market events, short-term interest
    rates and each Fund's asset volatility, are used to identify the most
    effective portfolio structure.
 .  Conduct rigorous analysis of new securities--The Investment Adviser's
    five-step process includes legal, credit, historical index and liquidity
    analysis, as well as price stress testing to determine suitability for
    money market mutual funds.
 
 3. Managing Liquidity
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .  Each Fund's clients and factors that influence their asset volatility;
 .  Technical events that influence the trading range of federal funds and
    other short-term fixed-income markets; and
 .  Bid-ask spreads associated with securities in the portfolios.
 
 Benchmarks for the Money Market Funds are the IBC Financial Data Universal
 Averages. Each Fund tracks the IBC Index which best corresponds to the
 Fund's eligible investments.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 .The Funds: Each Fund's securities are valued by the amortized cost method
  as permitted by Rule 2a-7 under the Investment Company Act of 1940, as
  amended (the "Act"). Under Rule 2a-7, each Fund may invest only in U.S.
  dollar-denominated securities that are determined to present minimal credit
  risk and meet certain other criteria including conditions relating to matu-
  rity, diversification and credit quality. These operating policies may be
  more restrictive than the fundamental policies set forth in the Statement
  of Additional Information (the "Additional Statement").
  .Taxable Funds: Prime Obligations, Money Market and Government Portfolios.
  .Tax-Exempt Funds: Tax-Exempt Diversified, Tax-Exempt California and Tax-
   Exempt New York Portfolios.
 .The Investors: The Funds are designed for investors seeking a high rate of
  return, a stable net asset value ("NAV") and convenient liquidation privi-
  leges. The Funds are particularly suitable for banks, corporations and
  other financial institutions that seek investment of short-term funds for
  their own accounts or for the accounts of their customers.
 .NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
 .Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .Investment Restrictions: Each Fund is subject to certain investment
  restrictions that are described in detail under "Investment Restrictions"
  in the Additional Statement. Fundamental investment restrictions and the
  investment objective of a Fund (except the Tax-Exempt California and Tax-
  Exempt New York Portfolios' objectives of providing shareholders with
  income exempt from California State and New York State and New York City
  personal income tax, respectively) cannot be changed without approval of a
  majority of the outstanding shares of that Fund. All investment policies
  not specifically designated as fundamental are non-fundamental and may be
  changed without shareholder approval.
 .Diversification: Diversification can help a Fund reduce the risks of
  investing. In accordance with current regulations of the Securities and
  Exchange Commission (the "SEC"), each Fund may not invest more than 5% of
  the value of its total assets at the time of purchase in the securities of
  any single issuer with these exceptions: (a) the Tax-Exempt California and
  Tax-Exempt New York
  Portfolios may each invest up to 25% of their total assets in five or fewer
  issuers; and (b) each of the other Funds may invest up to 25% of its total
  assets in the securities of a single issuer for up to three business days.
  These limitations do not apply to cash, certain repurchase agreements, U.S.
  Government Securities (as defined in Appendix A) or securities of other
  investment compa-
 
                                                                               3
<PAGE>
 
 
  nies. In addition, securities subject to certain unconditional guarantees
  and securities that are not "First Tier Securities" as defined by the SEC
  are subject to different diversification requirements as described in the
  Additional Statement.

Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 Taxable Funds:
 
 The Prime Obligations, Money Market and Government Portfolios seek to maxi-
 mize current income to the extent consistent with the preservation of capi-
 tal and the maintenance of liquidity by investing exclusively in high qual-
 ity money market instruments.
 
 The Prime Obligations and Money Market Portfolios pursue their investment
 objectives by investing in U.S. Government Securities, obligations of U.S.
 banks, commercial paper and other short-term obligations of U.S. companies,
 states, municipalities and other entities and repurchase agreements. The
 Money Market Portfolio may also invest in U.S. dollar-denominated obliga-
 tions of foreign banks, foreign companies and foreign governments.
 
 The Government Portfolio pursues its investment objective by investing in
 U.S. Government Securities and repurchase agreements relating to such
 securities.
 
 Tax-Exempt Funds:
 
 The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
 Portfolios seek to provide shareholders, to the extent consistent with the
 preservation of capital and prescribed portfolio standards, with a high
 level of income exempt from federal income tax by investing primarily in
 municipal instruments.
 
 In addition, the Tax-Exempt California and Tax-Exempt New York Portfolios
 seek to provide shareholders with income exempt from California State and
 New York State and City personal income taxes, respectively.
 
 The Tax-Exempt Funds pursue their investment objectives by investing in
 securities issued by or on behalf of states, territories, and possessions of
 the United States and their political subdivisions, agencies, authorities
 and instrumentalities, and the District of Columbia, the interest from
 which, if any, is in the opinion of bond counsel excluded from gross income
 for federal income tax purposes, and not an item of tax preference under the
 federal alternative minimum tax ("AMT").
 
                                                                               5

 2 If adverse economic conditions prevail in the banking industry (such as
   substantial losses on loans, increases in non-performing assets and charge-
   offs and declines in total deposits), the Fund may, for temporary defensive
   purposes, invest less than 25% of its total assets in bank obligations.
 3 To the extent required by Rule 2a-7, asset-backed and receivables-backed
   securities will be rated by the requisite number of nationally recognized

 5 Will only make such investments when yields on such securities are
   attractive compared to other taxable investments.
 6 Ordinarily expect that 100% of a Fund's portfolio securities will be
   invested in municipal obligations, but the Funds may, for temporary
   defensive purposes, hold cash or invest in short-term taxable securities.
 7 To the extent permitted by Rule 2a-7, securities without short-term ratings
   may be purchased if they are deemed to be of comparable quality to First
   Tier Securities, or to the extent that a Fund may purchase Second Tier
   Securities, comparable in quality to Second Tier Securities. In addition, a
   Fund holding a security supported by a guarantee or demand feature may rely
   on the credit quality of the guarantee or demand feature in determining the
   credit quality of the investment.
 8 If such policy should change, private activity bonds subject to AMT would
   not exceed 20% of a Fund's net assets under normal market conditions.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

Risks that apply to all Funds:
 
 .NAV Risk--The risk that a Fund will not be able to maintain a NAV per share of
 $1.00 at all times.
 .Interest Rate Risk--The risk that during periods of rising interest rates, a
 Fund's yield (and the market value of its securities) will tend to be lower
 than prevailing market rates; in periods of falling interest rates, a Fund's
 yield will tend to be higher.
 .Credit/Default Risk--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York Portfo-
 lios, risk of loss from payment default may also exist where municipal instru-
 ments are backed by foreign letters of credit or guarantees.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 .Liquidity Risk--The risk that a Fund will be unable to pay redemption proceeds
 within the time period stated in this Prospectus, because of unusual market
 conditions, an unusually high volume of redemption requests, or other reasons.
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Risk that applies to the Prime Obligations, Money Market and Government
Portfolios:
 
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market Portfolio:
 
 .Foreign Risk--The risk that a foreign security could lose value as a result of
 political, financial and economic events in foreign countries, less publicly
 available financial and other information, less stringent foreign securities
 regulations and accounting and disclosure standards, or other factors. The
 Money Market Portfolio may not invest more than 25% of its total assets in the
 securities of any one foreign government.
 .Banking Industry Risk--The risk that if the Fund invests more than 25% of its
 total assets in bank obligations, an adverse development in the banking indus-
 try may affect the value of the Fund's investments more than if the Fund's
 investments were not invested to such a degree in the banking industry. Nor-
 mally, the Money Market Portfolio intends to invest more than 25% of its total
 assets in bank obligations. Banks may be particularly susceptible to certain
 economic factors such as interest rate changes, adverse developments in the
 real estate market, fiscal and monetary policy and general economic cycles.
 
Risks that apply to the Tax-Exempt Funds:
 
 .Concentration Risk--The risk that if a Fund invests more than 25% of its total
 assets in issuers within the same state, industry or economic sector, an
 adverse economic, business or political development may affect the value of
 the Fund's investments more than if its investments were not so concentrated.
 The Tax-Exempt California and Tax-Exempt New York Portfolios intend to invest
 at least 65% of their total assets in California municipal obligations and New
 York munici-
 
                                                                              11

 pal obligations, respectively. These two Funds are classified as "non-diversi-
 fied" for regulatory purposes.
 .Tax Risk--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of a Fund to pay federal tax-
 exempt dividends (in the case of each of these Funds) and state tax-exempt
 dividends (in the case of the Tax-Exempt California and Tax-Exempt New York
 Portfolios).
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 Cash Management Shares of the Fund have less than one calendar year's per-
 formance. For this reason, the performance information shown below is for
 another class of shares (ILA Service Shares) that is not offered in this
 Prospectus but would have similar annual returns because both classes of
 shares will be invested in the same portfolio of securities. Annual returns
 will differ only to the extent that the classes do not have the same
 expenses. In reviewing this performance information, however, you should be
 aware that ILA Service Shares have a 0.40% (annualized) service fee while
 Cash Management Shares have borne distribution and service fees at 0.50% net
 of voluntary waivers since inception. If the expenses of the Cash Management
 Shares were reflected, performance would be reduced.
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's ILA
 Service Shares from year to year; and (b) the average annual returns of a
 Fund's ILA Service Shares. Investors should be aware that the fluctuation of
 interest rates is one primary factor in performance volatility. The bar
 chart and table assume reinvestment of dividends and distributions. A Fund's
 past performance is not necessarily an indication of how the Fund will per-
 form in the future. Performance reflects expense limitations in effect. If
 expense limitations were not in place, a Fund's performance would have been
 reduced. You may obtain a Fund's current yield by calling 1-800-621-2550.

/1/The Funds' annual operating expenses are based on actual expenses.
/2/Goldman Sachs has voluntarily agreed to limit a portion of the distribution
fees of each Fund to 0.07% of each Fund's average daily net assets. This limi-
tation may be terminated at any time at the option of Goldman Sachs. If this
occurs, the distribution fees of each Fund will increase to 0.50% of each
Fund's average daily net assets.
/3/Service Organizations may charge other fees directly to their customers who
are the beneficial owners of Cash Management Shares in connection with their
customers' accounts. Such fees may affect the return such customers realize
with respect to their investments.
/4/"Other Expenses" include transfer agency fees equal to 0.04% of the average
daily net assets of each Fund's Cash Management Shares plus all other ordinary
expenses not detailed above.
/5/The Investment Adviser has voluntarily agreed to reduce or limit "Total
Portfolio Operating Expenses" of each Fund (excluding taxes, interest,
brokerage fees, litigation, indemnification, distribution fees, service fees
and other extraordinary expenses) to 0.43% of each Fund's average daily net
assets. As a result of the current waivers and expense limitations, "Other
Expenses" and "Total Fund Operating Expenses" of the Funds which are actually
incurred are as set forth below. The expense limitations may be terminated at
any time at the option of the Investment Adviser with the approval of the
Trustees. If this occurs, "Other Expenses" and "Total Fund Operating Expenses"
may increase without shareholder approval.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in Cash Man-
agement Shares of a Fund for the time periods indicated and then redeem all of
your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that a Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

Service Organizations that invest in Cash Management Shares on behalf of their
customers may charge other fees directly to their customer accounts in connec-
tion with their investments. You should contact your Service Organization for
information regarding such charges. Such fees, if any, may affect the return
such customers realize with respect to their investment.
 
Certain Service Organizations may receive other compensation in connection with
the sale and distribution of Cash Management Shares or for services to their
customers' accounts and/or the Funds. For additional information regarding such
compensation, see "Shareholder Guide" in the Prospectus and "Other Information"
in the Additional Statement.

 .Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
 .Administers each Fund's business affairs
 .Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)
 
 Pursuant to an SEC order, each Taxable Fund may enter into principal trans-
 actions in certain taxable money market instruments, including repurchase
 agreements, with Goldman Sachs.

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future of its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent (the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.

                                                               SERVICE PROVIDERS
 
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.
 
                                                                              25

Dividends
 
All or substantially all of each Fund's net investment income will be declared
as a dividend daily. Dividends will normally, but not always, be declared as of
4:00 p.m. New York time as a dividend and distributed monthly. You may choose
to have dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 
You may indicate your election on your Account Application. Any changes may be
submitted in writing to Goldman Sachs at any time. If you do not indicate any
choice, dividends and distributions will be reinvested automatically in the
applicable Fund.
 
Dividends will be reinvested as of the last calendar day of each month. Cash
distributions normally will be paid on or about the first business day of each
month. Net short-term capital gains, if any, will be distributed in accordance
with federal income tax requirements and may be reflected in a Fund's daily
distributions.
 
Each Fund may distribute at least annually other realized capital gains, if
any, after reduction by available capital losses. In order to avoid excessive
fluctuations in the amount of monthly capital gains distributions, a portion of
any net capital gains realized on the disposition of securities during the
months of November and December may be distributed during the subsequent calen-
dar year. Although realized gains and losses on the assets of a Fund are
reflected in the NAV of the Fund, they are not expected to be of an amount
which would affect the Fund's NAV of $1.00 per share.

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Cash Manage-
 ment Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Cash Management Shares Of The Funds?
 Generally, Cash Management Shares may be purchased only through institutions
 that have agreed to provide account administration and personal and account
 maintenance services to their customers who are the beneficial owners of
 Cash Management Shares. These institutions are called "Service Organiza-
 tions." Customers of a Service Organization will normally give their pur-
 chase instructions to the Service Organization, and the Service Organization
 will, in turn, place purchase orders with Goldman Sachs. Service Organiza-
 tions will set times by which purchase orders and payments must be received
 by them from their customers. Generally, Cash Management Shares may be pur-
 chased from the Funds on any business day at their NAV next determined after
 receipt of an order by Goldman Sachs from a Service Organization. Shares
 begin earning dividends after the Fund's receipt of the purchase amount in
 federal funds. No sales load is charged.
 
 Service Organizations are responsible for transmitting purchase orders and
 payments to Goldman Sachs in a timely fashion. Service Organizations should
 place a purchase order in writing or by telephone.

 --------------------------------------------------------
</TABLE>
 
 Before or immediately after placing an initial purchase order, a Service
 Organization should complete and send to Goldman Sachs the Account Applica-
 tion attached to this Prospectus.
 
 Service Organizations may send their payments as follows:
 .Wire federal funds to The Northern Trust Company ("Northern"), as sub-
  custodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); or
 
                                                                              27
<PAGE>
 
 
 .Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; or
 .Send a check or Federal Reserve draft payable to Goldman Sachs Funds -
  (Name of Fund and Class of Shares), 4900 Sears Tower-60th Floor, Chicago,
  IL 60606-6372. The Funds will not accept a check drawn on a foreign bank or
  a third-party check.
 
 It is strongly recommended that payment be effected by wiring federal funds
 to Northern.
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.
 
 When Do Shares Begin Earning Dividends?
 Dividends begin to accrue as follows:

 What Do I Need To Know About Service Organizations?
 Service Organizations may provide the following services in connection with
 their customers' investments in Cash Management Shares:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 .Responding to inquiries from prospective and existing shareholders
 .Assisting customers with investment procedures
 .Developing, maintaining and supporting systems necessary to support
  accounts for cash management services
 
 In addition, some (but not all) Service Organizations are authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and may designate other interme-
 diaries to accept such orders, if approved by the Trust. In these cases:
 .A Fund will be deemed to have received an order in proper form when the
  order is accepted by the authorized Service Organization or intermediary on
  a
 
28
<PAGE>
 
                                                               SHAREHOLDER GUIDE
 
  business day, and the order will be priced at the Fund's NAV next deter-
  mined after such acceptance.
 .Service Organizations or intermediaries will be responsible for transmit-
  ting accepted orders and payments to the Trust within the time period
  agreed upon by them.
 
 You should contact your Service Organization directly to learn whether it is
 authorized to accept orders for the Trust.
 
 Pursuant to a service plan adopted by the Trust's Board of Trustees, Service
 Organizations are entitled to receive payment for their services from the
 Trust of up to 0.50% (on an annualized basis) of the average daily net
 assets of the Cash Management Shares of the Funds, which are attributable to
 or held in the name of the Service Organization for its customers.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Service Organizations and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Service
 Organizations depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses.
 
 In addition to Cash Management Shares, each Fund also offers other classes
 of shares to investors. These other share classes are subject to different
 fees and expenses (which affect performance), have different minimum invest-
 ment requirements and are entitled to different services than Cash Manage-
 ment Shares. Information regarding these other share classes may be obtained
 from your sales representative or from Goldman Sachs by calling the number
 on the back cover of this Prospectus.
 
 What Is My Minimum Investment In The Funds?
 The Funds do not have any minimum purchase or account requirements with
 respect to Cash Management Shares. A Service Organization may, however,
 impose a minimum amount for initial and subsequent investments in Cash Man-
 agement Shares, and may establish other requirements such as a minimum
 account balance. A Service Organization may redeem Cash Management Shares
 held by non-complying accounts, and may impose a charge for any special
 services.
 
                                                                              29
<PAGE>
 
 
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Modify or waive the minimum investment and minimum account balance require-
  ment.
 .Reject any purchase order for any reason.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Cash Management
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                     (Value of Assets of the Class)
          NAV =       - (Liabilities of the Class)
                -----------------------------------------
                Number of Outstanding Shares of the Class
 
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange
  (normally 4:00 p.m. New York time). Fund shares will be priced on any day
  the New York Stock Exchange is open, except for days on which Chicago, Bos-
  ton or New York banks are closed for local holidays.
 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able to at all times maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Cash Management Shares Of The Funds?
 Generally, Cash Management Shares may be sold (redeemed) only through Serv-
 ice Organizations. Customers of a Service Organization will normally give
 their redemption instructions to the Service Organization, and the Service
 Organization will, in turn, place redemption orders with the Funds. General-
 ly, each Fund will

 redeem its Cash Management Shares upon request on any business day at their
 NAV next determined after receipt of such request in proper form.
 A Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is elected on the Account Appli-
 cation.

 Certain Service Organizations are authorized to accept redemption requests
 on behalf of the Funds as described under "What Do I Need To Know About
 Service Organizations?" A redemption may also be made with respect to cer-
 tain Funds by means of the check redemption privilege.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
 .All telephone requests are recorded.
 .Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request may be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
                                                                              31

 When Will Redemption Proceeds Be Wired?
 Redemption proceeds will normally be wired to the bank account designated on
 a Service Organization's Account Application as follows:

                                                             request is received
 -------------------------------------------------------------------------------
</TABLE>
 
 .Although redemption proceeds will normally be wired as described above,
  each Fund reserves the right to pay redemption proceeds up to three busi-
  ness days following receipt of a properly executed wire transfer redemption
  request. If you are selling shares you recently paid for by check, the Fund
  will pay you when your check has cleared, which may take up to 15 days. If
  the Federal Reserve Bank is closed on the day that the redemption proceeds
  would ordinarily be wired, wiring the redemption proceeds may be delayed
  one additional business day.
 .Neither the Trust nor Goldman Sachs assumes any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organizations.
 
 What Should I Know About The Check Redemption Privilege?
 A Service Organization may elect to have a special account with State Street
 for the purpose of redeeming Cash Management Shares from its account by
 check. The following general policies govern the check redemption privilege:
 .The Service Organization will be provided with a supply of checks when
  State Street receives a completed signature card and authorization form.
  Checks drawn on the account may be payable to the order of any person in
  any amount over $500, but cannot be certified.
 .The payee of the check may cash or deposit it just like any other check
  drawn on a bank.

 .When the check is presented to State Street for payment, a sufficient num-
  ber of full or fractional Cash Management Shares will be redeemed to cover
  the amount of the check.
 .Canceled checks will be returned to the Service Organization by State
  Street.
 .The check redemption privilege allows a Service Organization to receive the
  dividends declared on the Cash Management Shares that are to be redeemed
  until the check is actually processed. Because of this feature, accounts
  may not be completely liquidated by check.
 .If the amount of the check is greater than the value of the Cash Management
  Shares held in the Service Organization's account, the check will be
  returned unpaid. In this case, the Service Organization may be subject to
  extra charges.
 .The Trust reserves the right to limit the availability of, modify or termi-
  nate the check redemption privilege at any time with respect to any or all
  Service Organizations.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 .Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
 .Redeem the Cash Management Shares of any Service Organization whose account
  balance falls below the minimum as a result of a redemption. The Fund will
  give 60 days' prior written notice to allow a Service Organization to pur-
  chase sufficient additional shares of the Fund in order to avoid such
  redemption.
 .Redeem your Cash Management Shares in other circumstances determined by the
  Board of Trustees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash)
  from the Fund. If you receive redemption proceeds in-kind, you should
  expect to incur transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Cash Management Shares of a Fund at NAV
 for shares of the corresponding class of any other Goldman Sachs Fund. The
 
                                                                              33

</TABLE>
 
 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund, except that this
  requirement may be waived at the discretion of the Trust.
 .Telephone exchanges normally will be made only to an identically registered
  account.
 .Shares may be exchanged among accounts with different names, addresses, and
  social security or other taxpayer identification numbers only if the
  exchange instructions are in writing and are signed by an authorized person
  designated on the Account Application.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs may use reasonable procedures described under "What Do I Need
  To Know About Telephone Redemption Requests?" in an effort to prevent unau-
  thorized or fraudulent telephone exchange requests.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.

 What Types Of Reports Will I Be Sent Regarding Investments In Cash
 Management Shares?
 Service Organizations will receive from the Funds annual reports containing
 audited financial statements and semiannual reports. Upon request, Service
 Organizations will also be provided with a printed confirmation for each
 transaction. Any dividends and distributions paid by the Funds are also
 reflected in regular statements issued by the Funds to Service Organiza-
 tions. Service Organizations are responsible for providing these or other
 reports to their customers who are the beneficial owners of Cash Management
 Shares in accordance with the rules that apply to their accounts with the
 Service Organizations.
 
 What Are The Distribution Fees Paid By Cash Management Shares?
 The Trust has adopted a distribution plan (the "Plan") to pay distribution
 fees for the sale and distribution of its shares. Because these fees are
 paid out of the Funds' assets on an ongoing basis, over time, these fees
 will increase the cost of your investment and may cost you more than paying
 other types of sales charges. If the fees received by Goldman Sachs pursuant
 to the Plan exceed its expenses, Goldman Sachs may realize a profit from
 this arrangement. Goldman Sachs pays the distribution fees on a quarterly
 basis.
 
 Under the Plan, Goldman Sachs is entitled to a monthly fee from each Fund
 for distribution services equal, on an annual basis, to 0.50% of a Fund's
 average daily net assets attributed to Cash Management Shares. Currently,
 Goldman Sachs has voluntarily agreed to limit the amount of such fees to
 0.07% of a Fund's average daily net assets attributed to Cash Management
 Shares. As of the date of this Prospectus, Goldman Sachs has no intention of
 modifying or discontinuing such limitation, but may do so in the future at
 its discretion.
 
 The distribution fees are subject to the requirements of Rule 12b-1 under
 the Act, and may be used (among other things) for:
 .Compensation paid to and expenses incurred by Service Organizations,
  Goldman Sachs and their respective officers, employees and sales
  representatives;
 .Commissions paid to Service Organizations;
 .Allocable overhead;
 .Telephone and travel expenses;
 .Interest and other costs associated with the financing of such compensation
  and expenses;
 .Printing of prospectuses for prospective shareholders;
 .Preparation and distribution of sales literature or advertising of any
  type; and
 .All other expenses incurred in connection with activities primarily
  intended to result in the sale of Cash Management Shares.
 
                                                                              35

Taxation
 
 
Each Fund intends to qualify as a regulated investment company for federal tax
purposes, and to distribute to shareholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Funds, Fund dividends will generally be taxable to
you as ordinary income (unless your investment is in an IRA or other tax-
advantaged account) regardless of whether you reinvest in additional shares or
take them as cash. The Tax-Exempt Funds expect generally to distribute "exempt-
interest dividends," which will be tax-exempt income for federal income tax
purposes. Moreover, the Tax-Exempt California and Tax-Exempt New York Portfo-
lios expect that their dividends will not be subject to the California and New
York personal income tax (and in the case of the Tax-Exempt New York Portfolio,
New York City personal income tax). The tax status and amounts of the dividends
for each calendar year will be detailed in your annual tax statement from the
Fund.
 
Dividends and distributions from each Fund will generally be taxable to you in
the tax year in which they are paid, with one exception. Dividends and distri-
butions declared by a Fund in October, November or December and paid in January
are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry shares of the
Tax-Exempt Funds generally will not be deductible for income tax purposes.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Funds may be an item of tax preference for purposes of determining
your federal alternative minimum tax liability. Exempt-interest dividends will
also be considered along with other adjusted gross income in determining
whether any social security or railroad retirement payments received by you are
subject to federal income taxes.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from any Fund (including the Tax-Exempt Funds)
or on the value of the shares held by you. More tax information is provided in
the Additional Statement. You should also consult your own tax adviser for
information regarding all tax consequences applicable to your investments in
the Funds.

Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Funds, including their associated
risks. Additional information is provided in the Additional Statement, which is
available upon request. Among other things, the Additional Statement describes
certain fundamental policies and investment restrictions that cannot be changed
without shareholder approval. You should note, however, that all policies not
specifically designated as fundamental are non-fundamental and may be changed
without shareholder approval. If there is a change in a Fund's investment
objective, you should consider whether that Fund remains an appropriate invest-
ment in light of your then current financial position and needs.
 
U.S. Treasury Obligations and U.S. Government Securities and Related Custodial
Receipts. U.S. Treasury Obligations include securities issued or guaranteed by
the U.S. Treasury ("U.S. Treasury Obligations"). Payment of principal and
interest on these obligations is backed by the full faith and credit of the
U.S. government. U.S. Treasury Obligations include, among other things, the
separately traded principal and interest components of securities guaranteed or
issued by the U.S. Treasury if such components are traded independently under
the Separate Trading of Registered Interest and Principal of Securities program
("STRIPS").
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.
 
                                                                              37

U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Certain Funds may also acquire U.S. Government Securities in the form of custo-
dial receipts. Custodial receipts evidence ownership of future interest pay-
ments, principal payments or both on notes or bonds issued or guaranteed as to
principal and interest by the U.S. government, its agencies, instrumentalities,
political subdivisions or authorities. For certain securities law purposes,
custodial receipts are not considered obligations of the U.S. government.
 
Bank Obligations. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. Certain Funds may invest in obligations issued or
backed by U.S. banks when a bank has more than $1 billion in total assets at
the time of purchase or is a branch or subsidiary of such a bank, U.S. dollar-
denominated obligations issued or guaranteed by foreign banks that have more
than $1 billion in total assets at the time of purchase, U.S. branches of such
foreign banks (Yankee obligations), foreign branches of such foreign banks and
foreign branches of U.S. banks having more than $1 billion in total assets at
the time of purchase. Bank obligations may be general obligations of the parent
bank or may be limited to the issuing branch by the terms of the specific
obligation or by government regulation.
 
If a Fund invests more than 25% of its total assets in bank obligations
(whether foreign or domestic), it may be especially affected by favorable and
adverse developments in or related to the banking industry. The activities of
U.S. and most foreign banks are subject to comprehensive regulations which, in
the case of U.S. regulations, have undergone substantial changes in the past
decade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of opera-
tions and profitability of domestic and foreign banks. Significant developments
in the U.S. banking industry have included increased competition from other
types of financial institutions, increased acquisition activity and geographic
expansion. Banks may be particularly susceptible to certain economic factors,
such as interest rate changes and adverse developments in the real estate mar-
kets. Fiscal and monetary policy and general economic cycles can affect the
availability and cost of funds, loan demand and asset quality and thereby
impact the earnings and financial conditions of banks.
 
Commercial Paper. A Fund may invest in commercial paper, including variable
amount master demand notes and asset-backed commercial paper. Commercial paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, finance companies and other issuers.
The com-

                                                                      APPENDIX A
 
mercial paper purchased by a Fund consists of direct U.S. dollar-denominated
obligations of domestic or, in the case of a certain Funds, foreign issuers.
 
Short-Term Obligations. A Fund may invest in other short-term obligations,
including short-term funding agreements payable in U.S. dollars and issued or
guaranteed by U.S. corporations, foreign corporations or other entities. A
funding agreement is a contract between an issuer and a purchaser that obli-
gates the issuer to pay a guaranteed rate of interest on a principal sum depos-
ited by the purchaser. Funding agreements will also guarantee a stream of pay-
ments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and guaran-
teed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Fund will be regarded as
illiquid.
 
Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
asset-backed and receivables-backed securities whose principal and interest
payments are collateralized by pools of assets such as auto loans, credit card
receivables, leases, installment contracts and personal property. Asset-backed
and receivables-backed securities are often subject to more rapid repayment
than their stated maturity date would indicate as a result of the pass-through
of prepayments of principal on the underlying loans. During periods of declin-
ing interest rates, prepayment of loans underlying asset-backed and receiv-
ables-backed securities can be expected to accelerate. Accordingly, a Fund's
ability to maintain positions in such securities will be affected by reductions
in the principal amount of such securities resulting from prepayments, and its
ability to reinvest the returns of principal at comparable yields is subject to
generally prevailing interest rates at that time. In addition, securities that
are backed by credit card, automobile and similar types of receivables gener-
ally do not have the benefit of a security interest in collateral that is com-
parable in quality to mortgage assets. There is the possibility that, in some
cases, recoveries on repossessed collateral may not be available to support
payments on these securities. In the event of a default, a Fund may suffer a
loss if it cannot sell collateral quickly and receive the amount it is owed.
 
Foreign Government Obligations and Related Foreign Risks. Certain Funds may
invest in foreign government obligations. Foreign government obligations are
U.S. dollar-denominated obligations (limited to commercial paper and other
notes) issued or guaranteed by a foreign government or other entity located or
organized in a foreign country that maintains a short-term foreign currency
rating in the highest short-term ratings category by the requisite number of
NRSROs.
 
Investments by a Fund in foreign securities, whether issued by a foreign gov-
ernment, bank, corporation or other issuer, may present a greater degree of
risk than investments in securities of domestic issuers because of less public-
ly-available financial
 
                                                                              39

and other information, less securities regulation, potential imposition of for-
eign withholding and other taxes, war, expropriation or other adverse govern-
mental actions. Efforts in foreign countries to remediate potential Year 2000
problems are not as extensive as those in the United States. As a result, the
operations of foreign markets, foreign issuers and foreign governments may be
disrupted by the Year 2000 Problem, and the investment portfolio of a Fund may
be adversely affected. Foreign banks and their foreign branches are not regu-
lated by U.S. banking authorities, and generally are not bound by the account-
ing, auditing and financial reporting standards applicable to U.S. banks.
 
Repurchase Agreements. Each Fund may enter into repurchase agreements with
primary dealers in U.S. Government Securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund are less than the repurchase price and the Fund's
cost associated with delay and enforcement of the repurchase agreement. In
addition, in the event of bankruptcy of the seller, a Fund could suffer addi-
tional losses if a court determines that the Fund's interest in the collateral
is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, each Fund, together with other registered investment
companies having advisory agreements with the Investment Adviser or any of its
affiliates, may transfer uninvested cash balances into a single joint account,
the daily aggregate balance of which will be invested in one or more repurchase
agreements.
 
Municipal Obligations. Certain Funds may invest in municipal obligations.
Municipal obligations are issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies,
authorities and instrumentalities, and the District of Columbia. Municipal
obligations may include fixed rate notes and similar debt instruments; variable
and floating rate demand instruments; tax-exempt commercial paper; municipal
bonds; and unrated notes, paper, bonds or other instruments.
 
Municipal Notes and Bonds. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds

<PAGE>
 
                                                                      APPENDIX A
 
also include lease rental revenue bonds which are issued by a state or local
authority for capital projects and are secured by annual lease payments from
the state or locality sufficient to cover debt service on the authority's obli-
gations. Industrial development bonds ("private activity bonds") are a specific
type of revenue bond backed by the credit and security of a private user and,
therefore, have more potential risk. Municipal bonds may be issued in a variety
of forms, including commercial paper, tender option bonds and variable and
floating rate securities.
 
Tender Option Bonds. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Fund's average portfolio maturity. There is a risk that a Fund will not be con-
sidered the owner of a tender option bond for federal income tax purposes, and
thus will not be entitled to treat such interest as exempt from federal income
tax. Certain tender option bonds may be illiquid or may become illiquid as a
result of a credit rating downgrade, a payment default or a disqualification
from tax-exempt status.
 
Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which include a demand feature that permits the
holder to sell the RAWs to a bank or other financial institution at a purchase
price equal to par plus accrued interest on each interest rate reset date.
 
Industrial Development Bonds. Certain Funds may invest in industrial develop-
ment bonds (private activity bonds). Industrial development bonds are a spe-
cific type of revenue bond backed by the credit and security of a private user,
the interest from which would be an item of tax preference when distributed by
a Fund as "exempt-interest dividends" to shareholders under the AMT.
 
                                                                              41
<PAGE>
 
 
 
Other Municipal Obligation Policies. Certain Funds may invest 25% or more of
the value of their respective total assets in municipal obligations which are
related in such a way that an economic, business or political development or
change affecting one municipal obligation would also affect the other municipal
obligation. For example, a Fund may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of a Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political developments affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality of these banks and financial institutions could,
therefore, cause a loss to a Fund that invests in municipal obligations. Let-
ters of credit and other obligations of foreign banks and financial institu-
tions may involve risks in addition to those of domestic obligations because of
less publicly available financial and other information, less securities regu-
lation, potential imposition of foreign withholding and other taxes, war,
expropriation or other adverse governmental actions. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities and generally
are not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks. In addition, the Funds may acquire securities in the
form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.
 
Floating and Variable Rate Obligations. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Fund may consider the maturity of a variable or floating rate obli-
gation to be shorter than its ultimate stated maturity if the obligation is a
U.S. Treasury Obligation or U.S. Government Security, if the obligation has a
remaining maturity of 397 calendar days or less, or if the obligation has a
demand feature that permits the Fund to receive payment at any time or at spec-
ified intervals not exceeding 397 calendar days. The issuers or financial

                                                                      APPENDIX A
 
intermediaries providing demand features may support their ability to purchase
the obligations by obtaining credit with liquidity supports. These may include
lines of credit, which are conditional commitments to lend and letters of cred-
it, which will ordinarily be irrevocable, both of which may be issued by domes-
tic banks or foreign banks which have a branch, agency or subsidiary in the
United States. A Fund may purchase variable or floating rate obligations from
the issuers or may purchase certificates of participation, a type of floating
or variable rate obligation, which are interests in a pool of debt obligations
held by a bank or other financial institution.
 
When-Issued Securities and Forward Commitments. The Funds may purchase when-
issued securities and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. When-issued securities
are securities that have been authorized, but not yet issued. When-issued secu-
rities are purchased in order to secure what is considered to be an advanta-
geous price and yield to a Fund at the time of entering into the transaction. A
forward commitment involves entering into a contract to purchase or sell secu-
rities for a fixed price at a future date beyond the customary settlement peri-
od.
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Fund will generally purchase
securities on a when-issued or forward commitment basis with the intention of
acquiring securities for its portfolio, a Fund may dispose of when-issued secu-
rities or forward commitments prior to settlement if the Investment Adviser
deems it appropriate.
 
Other Investment Companies. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Act. These limitations
include a prohibition on any Fund acquiring more than 3% of the voting shares
of any other investment company, and a prohibition on investing more than 5% of
a Fund's total assets in securities of any one investment company or more than
10% of its total assets in securities of all investment companies. A Fund will
indirectly bear its proportionate share of any management fees and other
expenses paid by such other investment companies. Such other investment compa-
nies will have investment objectives, policies and restrictions substantially
similar to those of the acquiring Fund and will be subject to substantially the
same risks.
 
Illiquid Securities. Each Fund may invest up to 10% of its net assets in illiq-
uid securities which cannot be disposed of in seven days in the ordinary course
of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 
                                                                              43
<PAGE>
 
 
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
Downgraded Securities. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.
 
Special Risks and Policies Applicable to the Tax-Exempt Funds:
 
Fundamental Policies. As a matter of fundamental policy, at least 80% of each
of the net assets of each of the Tax-Exempt Diversified, Tax-Exempt California
and Tax-Exempt New York Portfolios will ordinarily be invested in municipal
obligations, the interest from which is, in the opinion of bond counsel, if
any, excluded from gross income for federal income tax purposes. In addition,
as a matter of fundamental policy, at least 65% of each of the Tax-Exempt Cali-
fornia and Tax-Exempt New York Portfolio's total assets will be invested in
California and New York municipal obligations, except in extraordinary circum-
stances.
 
For these purposes, California and New York municipal obligations are obliga-
tions issued by or on behalf of the State of California or the State of New
York, respectively, and their respective political subdivisions, agencies and
instrumentalities and the government of Puerto Rico, the U.S. Virgin Islands
and Guam, the interest from which is excluded from gross income for federal
income tax purposes and is exempt from California State personal income tax or
New York State and New York City personal income tax. Each Tax-Exempt Fund may
temporarily invest in taxable money market instruments or, in the case of the
Tax-Exempt California and New York Portfolios, in municipal obligations that
are not California or New York municipal obligations, respectively, when
acceptable California and New York municipal obligations are not available or
when the Investment Adviser believes that the market conditions dictate a
defensive posture. Investments in taxable money market instruments will be lim-
ited to those meeting the quality standards of each Tax-Exempt Fund. The Tax-
Exempt California and Tax-Exempt New York Portfolios' distributions of interest
from municipal obligations other than California and New York

                                                                      APPENDIX A
 
municipal obligations, respectively, may be subject to California and New York
State and New York City personal income taxes.
 
Risks of Investing in California and New York: The Tax-Exempt California and
Tax-Exempt New York Portfolios concentrate their investments in California and
New York municipal obligations. Consequently, these Funds are more susceptible
to factors adversely affecting issuers of California and New York municipal
obligations, and may be riskier than comparable municipal bond funds and money
market funds that do not emphasize these issuers to this degree.
 
The Tax-Exempt California Portfolio's investments can be affected by political
and economic developments within the State of California (the "State"), and by
the financial condition of the State, its public authorities and political sub-
divisions. After suffering a severe recession in the early 1990's which caused
the State to experience financial difficulties, California's economy entered a
sustained recovery since late 1993 and the State's budget has returned to a
positive balance. California's long-term credit rating has been raised after
being reduced during the recession. To respond to its own revenue shortfalls
during the recession, the State reduced assistance to its public authorities
and political subdivisions. Cutbacks in state aid could further adversely
affect the financial condition of cities, counties and education districts
which are subject to their own fiscal constraints. California voters in the
past have passed amendments to the California Constitution and other measures
that limit the taxing and spending authority of California governmental enti-
ties, and future voter initiatives could result in adverse consequences affect-
ing California municipal obligations. Also, the ultimate fiscal effect of
federally-mandated reform of welfare programs on the State and its local gov-
ernments is still to be resolved.
 
These factors, among others (including the outcome of related pending litiga-
tion), could reduce the credit standing of certain issuers of California munic-
ipal obligations. A more detailed discussion of the risks of investing in Cali-
fornia is included in the Additional Statement.
 
The Tax-Exempt New York Portfolio's investments will be affected by political
and economic developments within the State of New York (the "State"), and by
the financial conditions of the State, its public authorities and political
subdivisions, particularly the City of New York (the "City"). The State and the
City face long-term economic problems that could seriously affect their ability
and that of other issuers of New York municipal obligations to meet their
financial obligations. Certain substantial issuers of New York municipal obli-
gations (including issuers whose obligations may be acquired by the Fund) have
experienced serious financial difficulties in recent years. These difficulties
have at times jeopardized the credit standing and impaired the borrowing abili-
ties of all New York issuers and have generally contributed to higher interest

obligations. Although several different issues of municipal obligations of the
State and its agencies and instrumentalities and of the City have been down-
graded by S&P and Moody's in recent years, S&P and Moody's have recently placed
the debt obligations of the State on Credit Watch with positive implications
and upgraded the debt obligations of the City, respectively. Strong demand for
New York municipal obligations has also at times had the effect of permitting
New York municipal obligations to be issued with yields relatively lower, and
after issuance, to trade in the market at prices relatively higher, than compa-
rably rated municipal obligations issued by other jurisdictions. A recurrence
of the financial difficulties previously experienced by certain issuers of New
York municipal obligations could result in defaults or declines in the market
values of those issuers' existing obligations and, possibly, in the obligations
of other issuers of New York municipal obligations. Although as of April 1,
1999 no issuers were in default with respect to the payment of their New York
municipal obligations, the occurrence of any such default could materially
affect adversely the market values and marketability of all New York municipal
obligations and, consequently, the value of the Fund's holdings. A more
detailed discussion of the risks of investing in New York is included in the
Additional Statement.
 
If California, New York, or any of their local governmental entities are unable
to meet their financial obligations, the corresponding Fund's income, NAV,
ability to preserve or realize appreciation of capital or liquidity could be
adversely affected. Also, neither of these Funds is a diversified fund under
the Act (except to the extent that diversification is required by Rule 2a-7 or
for federal income tax purposes). Because they may invest a larger percentage
of their assets in the securities of fewer issuers than do diversified funds,
these Funds may be exposed to greater risk in that an adverse change in the
condition of one or a small number of issuers would have a greater impact on
them.

Appendix B
Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Institutional Liquid Assets Portfolios (the "Funds"). GSAM is referred to in
 this Prospectus as the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Money Market Funds are managed to seek the preservation of capital,
 daily liquidity and maximum current income. With each Fund the Investment
 Adviser follows a conservative, risk-managed investment process that seeks
 to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 Investment Process
 
 
 1.Managing Credit Risk
 
 The Investment Adviser's process for managing risk emphasizes:
 .Intensive research--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Funds. Sources for their
  analysis include third-party inputs, such as financial statements and media
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .Timely updates--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 The Result: An "approved" list of high-quality credits--The Investment
 Adviser's portfolio management team uses this approved list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
                                                                               1
<PAGE>
 
 
 
 2.Managing Interest Rate Risk
 
 Three main steps are followed in seeking to manage interest rate risk:
 .Establish weighted average maturity (WAM) target--WAM (the weighted average
  time until the yield of a portfolio reflects any changes in the current
  interest rate environment) is constantly revisited and adjusted as market
  conditions change. An overall strategy is developed by the portfolio
  management team based on insights gained from weekly meetings with both
  Goldman Sachs economists and economists from outside the firm.
 .Implement optimum portfolio structure--Proprietary models that seek the
  optimum balance of risk and return, in conjunction with the Investment
  Adviser's analysis of factors such as market events, short-term interest
  rates and each Fund's asset volatility, are used to identify the most
  effective portfolio structure.
 .Conduct rigorous analysis of new securities--The Investment Adviser's five-
  step process includes legal, credit, historical index and liquidity
  analysis, as well as price stress testing to determine suitability for
  money market mutual funds.
 
 3. Managing Liquidity
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .Each Fund's clients and factors that influence their asset volatility;
 .Technical events that influence the trading range of federal funds and
  other short-term fixed-income markets; and
 .Bid-ask spreads associated with securities in the portfolios.
 
 Benchmarks for the Money Market Funds are the IBC Financial Data Universal
 Averages. Each Fund tracks the IBC Index which best corresponds to the
 Fund's eligible investments.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 
 .The Funds: Each Fund's securities are valued by the amortized cost method
  as permitted by Rule 2a-7 under the Investment Company Act of 1940, as
  amended (the "Act"). Under Rule 2a-7, each Fund may invest only in U.S.
  dollar-denominated securities that are determined to present minimal credit
  risk and meet certain other criteria, including those conditions relating
  to maturity, diversification and credit quality. These operating policies
  may be more restrictive than the fundamental policies set forth in the
  Statement of Additional Information (the "Additional Statement").
  .Taxable Fund: Prime Obligations Portfolio
  .Tax-Exempt Fund: Tax-Exempt Diversified Portfolio
 .The Investors: The Funds are designed for investors seeking a high rate of
  return, a stable net asset value ("NAV") and convenient liquidation privi-
  leges.
 .NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
 .Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .Investment Restrictions: Each Fund is subject to certain investment
  restrictions that are described in detail under "Investment Restrictions"
  in the Additional Statement. Fundamental investment restrictions and the
  investment objective of a Fund cannot be changed without approval of a
  majority of the outstanding shares of that Fund. All investment policies
  not specifically designated as fundamental are non-fundamental and may be
  changed without shareholder approval.
 .Diversification: Diversification can help a Fund reduce the risks of
  investing. In accordance with current regulations of the Securities and
  Exchange Commission (the "SEC"), each Fund may not invest more than 5% of
  the value of its total assets at the time of purchase in the securities of
  any single issuer except that each Fund may invest up to 25% of its total
  assets in the securities of a single issuer for up to three business days.
  These limitations do not apply to cash, certain repurchase agreements, U.S.
  Government Securities (as defined in Appendix A) or securities of other
  investment companies. In addition, securities subject to certain uncondi-
  tional guarantees and securities that are not "First Tier Securities" as
  defined by the SEC are subject to different diversification requirements as
  described in the Additional Statement.
 
                                                                               3

Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 Taxable Fund:
 
 The Prime Obligations Portfolio seeks to maximize current income to the
 extent consistent with the preservation of capital and the maintenance of
 liquidity by investing exclusively in high quality money market instruments.
 
 The Prime Obligations Portfolio pursues its investment objective by invest-
 ing in U.S. Government Securities, obligations of U.S. banks, commercial
 paper and other short-term obligations of U.S. companies, states, municipal-
 ities and other entities and repurchase agreements.
 
 Tax-Exempt Fund:
 
 The Tax-Exempt Diversified Portfolio seeks to provide shareholders, to the
 extent consistent with the preservation of capital and prescribed portfolio
 standards, with a high level of income exempt from federal income tax by
 investing primarily in municipal instruments.
 
 As a matter of fundamental policy, at least 80% of the net assets of the
 Tax-Exempt Diversified Portfolio will ordinarily be invested in securities
 issued by or on behalf of states, territories, and possessions of the United
 States and their political subdivisions, agencies, authorities and instru-
 mentalities, and the District of Columbia, the interest from which, if any,
 is, in the opinion of bond counsel excluded from gross income for federal
 income tax purposes.

 PRINCIPAL INVESTMENT STRATEGIES
 
 The table below identifies some of the investment techniques that may (but
 are not required to) be used by the Funds in seeking to achieve their
 investment objectives. The table also highlights the differences among the
 Funds in their use of these techniques and other investment practices and
 investment securities. Numbers in this table show allowable usage only; for
 actual usage, consult the Funds' annual/semiannual reports. For more infor-
 mation see Appendix A.

 Note: See Appendix A for a description of, and certain criteria applicable
 to, each of these categories of investments.
  1 Issued or guaranteed by the U.S. Treasury.
  2 Will only make such investments when yields on such securities are
    attractive compared to other taxable investments.
  3 Ordinarily expect that 100% of the Fund's portfolio securities will be
    invested in municipal obligations, but the Fund may, for temporary
    defensive purposes, hold cash or invest in short-term taxable securities.
  4 To the extent permitted by Rule 2a-7, securities without short-term
    ratings may be purchased if they are deemed to be of comparable quality
    to First Tier Securities, or to the extent that a Fund may purchase
    Second Tier Securities, comparable in quality to Second Tier Securities.
    In addition, a Fund holding a security supported by a guarantee or demand
    feature may rely on the credit quality of the guarantee or demand feature
    in determining the credit quality of the investment.
  5 To the extent required by Rule 2a-7, asset-backed and receivables-backed
    securities will be rated by the requisite number of nationally recognized
    statistical rating organizations ("NRSROs").
  6 If such policy should change, private activity bonds subject to AMT would
    not exceed 20% of the Fund's net assets under normal market conditions.
    No more than 25% of the value of the Fund's total assets may be invested
    in industrial development bonds or similar obligations where the non-
    governmental entities supplying the revenues from which such bonds or
    obligations are to be paid are in the same industry.
  7 First Tier Securities are (a) rated in the highest short-term rating
    category by at least two NRSROs, or if only one NRSRO has assigned a
    rating, by that NRSRO; or (b) issued or guaranteed by, or otherwise allow
    a Fund under certain conditions to demand payment from, an entity with
    such ratings. U.S. Government Securities are considered First Tier
    Securities.
  8 Second Tier Securities are (a) rated in the top two short-term rating
    categories by at least two NRSROs, or if only one NRSRO has assigned a
    rating, by that NRSRO; or (b) issued or guaranteed by, or otherwise allow
    a Fund under certain conditions to demand payment from, an entity with
    such ratings.
  9 See "Taxation" below for an explanation of the tax consequences
    summarized in the table above.
 10 Taxable in many states except for distributions from U.S. Treasury
    Obligation interest income and certain U.S. Government Securities
    interest income.
 11 Taxable except for distributions from interest on obligations of an
    investor's state of residence in certain states.

Principal Risks of the Funds
 
Loss of money is a risk of investing in each Fund. An investment in a Fund is
not a deposit of any bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following
summarizes important risks that apply to the Funds and may result in a loss of
your investment. None of the Funds should be relied upon as a complete invest-
ment program. There can be no assurance that a Fund will achieve its investment
objective.

Risks that apply to each Fund:
 
 .NAV Risk--The risk that a Fund will not be able to maintain a NAV per share of
 $1.00 at all times.
 .Interest Rate Risk--The risk that during periods of rising interest rates, a
 Fund's yield (and the market value of its securities) will tend to be lower
 than prevailing market rates; in periods of falling interest rates, a Fund's
 yield will tend to be higher.
 .Credit/Default Risk--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Exempt Diversified Portfolio, risk of loss from payment default may also
 exist where municipal instruments are backed by foreign letters of credit or
 guarantees.
 .Liquidity Risk--The risk that a Fund will be unable to pay redemption proceeds
 within the time period stated in this Prospectus, because of unusual market
 conditions, an unusually high volume of redemption requests, or other reasons.
 
                                                                               7
<PAGE>
 
 
 .Other Risks--Each Fund is subject to other risks, such as the risk that its
 operations, or the value of its portfolio securities, will be disrupted by the
 "Year 2000 Problem."
 
Risk that applies to the Prime Obligations Portfolio:
 
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government, agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Tax-Exempt Diversified Portfolio:
 
 .Concentration Risk--The risk that if the Fund invests more than 25% of its
 total assets in issuers within the same state, industry or economic sector, an
 adverse economic, business or political development may affect the value of
 the Fund's investments more than if its investments were not so concentrated.
 .Tax Risk--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of the Fund to pay federal tax-
 exempt dividends.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of the Funds' Serv-
 ice Shares from year to year; and (b) the average annual returns of the
 Funds' Service Shares and the Prime Obligation Fund's Class B and C Shares.
 Investors should be aware that the fluctuation of interest rates is one pri-
 mary factor in performance volatility. The bar chart and table assume rein-
 vestment of dividends and distributions. A Fund's past performance is not
 necessarily an indication of how the Fund will perform in the future. The
 average annual total return reflects the assumed contingent deferred sales
 charge ("CDSC") for Class B Shares (5% maximum declining to 0% after six
 years) and the assumed CDSC for Class C Shares (1% if redeemed within 12
 months of purchase). Service Shares are not subject to any initial sales
 charge or CDSC. Performance reflects expense limitations in effect. If
 expense limitations were not in place, a Fund's performance would have been
 reduced. You may obtain a Fund's current yield by calling 1-800-621-2550.

+Investors wishing to purchase shares of the Prime Obligations Portfolio are
generally required to purchase ILA Service Shares. ILA Class B and Class C
Shares of the Prime Obligations Portfolio will typically be in exchange for
Class B or Class C Shares, respectively, of another Goldman Sachs Fund.
/1/The maximum CDSC is a percentage of the lesser of the NAV at the time of
redemption or the NAV when the shares were originally purchased.
/2/A CDSC is imposed upon Class B Shares redeemed within six years of purchase
(or initial investment in a Goldman Sachs Fund from which an exchange is made)
at a rate of 5% in the first year, declining to 1% in the sixth year, and elim-
inated thereafter.
/3/A CDSC of 1% is imposed on Class C Shares redeemed within 12 months of pur-
chase (or initial investment in a Goldman Sachs Fund from which an exchange is
made).
/4/A transaction fee of $7.50 may be charged for redemption proceeds paid by
wire. In addition to free reinvestments of dividends and distributions in
shares of other Goldman Sachs Funds and free automatic exchanges pursuant to
the Automatic Exchange Program, six free exchanges are permitted in each
12-month period. A fee of $12.50 may be charged for each subsequent exchange
during such period.
/5/The Funds' annual operating expenses are based on actual expenses.
/6/Service Organizations may charge other Fees directly to their customers who
are the beneficial owners of ILA Service Shares in connection with their cus-
tomers' accounts. Such fees may affect the return such customers realize with
respect to their investments.
/7/"Other Expenses" include transfer agency fees equal to 0.04% of the average
daily net assets of each class plus all other ordinary expenses not detailed
above.
/8/The Investment Adviser has voluntarily agreed to reduce or limit "Total Fund
Operating Expenses" of each Fund (excluding distribution fees, service fees,
taxes, interest and brokerage fees and litigation, indemnification and other
extraordinary expenses) to 0.43% of a Fund's average daily net assets. The
expense limitation may be terminated at any time at the option of the Invest-
ment Adviser with the approval of the Trustees. If this occurs, "Other
Expenses" and "Total Fund Operating Expenses" may increase without shareholder
approval.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the expense limitations) with the cost of investing in other
mutual funds. The Example assumes that you invest $10,000 in Service, Class B
or Class C Shares of a Fund, for the time periods indicated and then redeem all
of your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that a Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

*ILA Class B Shares convert to ILA Service Shares eight years after purchase;
therefore, ILA Class B expenses in the hypothetical example above assume this
conversion.
 
Service Organizations that invest in Service Shares on behalf of their custom-
ers may charge other fees directly to their customer accounts in connection
with their investments. You should contact your Service Organization for infor-
mation regarding such charges. Such fees, if any, may affect the return such
customers realize with respect to their investment.
 
Certain institutions may receive other compensation in connection with the sale
and distribution of shares or for services to their customers' accounts and/or
the Funds. For additional information regarding such compensation, see "Share-
holder Guide" in the Prospectus and "Other Information" in the Additional
Statement.

Service Providers
 
 
 INVESTMENT ADVISER
 
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. The Goldman Sachs Group,
 L.P., which controls the Investment Adviser, announced that it will pursue
 an initial public offering of the firm in the late spring or early summer of
 1999. Simultaneously with the offering, the Goldman Sachs Group, L.P. will
 merge into The Goldman Sachs Group, Inc. As of February 28, 1999, GSAM,
 together with its affiliates, acted as investment adviser or distributor for
 assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
 .Continually manages each Fund, including the purchase, retention and
  disposition of securities and other assets
 .Administers each Fund's business affairs
 .Performs various recordholder servicing functions (to the extent not
  provided by other organizations)
 
 Pursuant to an SEC order, the Prime Obligations Portfolio may enter into
 principal transactions in certain taxable money market instruments, includ-
 ing repurchase agreements, with Goldman Sachs.
 
 MANAGEMENT FEES
 
 
 As compensation for its services and its assumption of certain expenses, the
 Investment Adviser is entitled to the following fees, computed daily and
 payable monthly, at the annual rates listed below:
 
<TABLE>
<CAPTION>
                                           Actual Rate For the

  Fund                    Contractual Rate December 31, 1998

 -------------------------------------------------------------
  Tax-Exempt Diversified       0.35%              0.29%
 -------------------------------------------------------------
</TABLE>
 
 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Funds' transfer agent ( the "Transfer Agent") and, as such, performs various
 shareholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
                                                                              15
<PAGE>
 
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Funds' other service providers will be suffi-
 cient to avoid any adverse effect on the Funds due to the Year 2000 Problem.

Dividends
 
 All or substantially all of each Fund's net investment income will be
 declared as a dividend daily. Dividends will normally, but not always, be
 declared as of 4:00 p.m. New York time as a dividend and distributed month-
 ly. You may choose to have dividends paid in:
 .Cash
 .Additional shares of the same class of the same Fund
 
 You may indicate your election on your Account Application. Any changes may
 be submitted in writing to Goldman Sachs at any time. If you do not indicate
 any choice, dividends and distributions will be reinvested automatically in
 the applicable Fund.
 
 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and December may be distributed during the
 subsequent calendar year. Although realized gains and losses on the assets
 of a Fund are reflected in the NAV of the Fund, they are not expected to be
 of an amount which would affect the Fund's NAV of $1.00 per share.
 
                                                                              17

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Shares Of The Funds?
 Each Fund offers Service Shares, and the Prime Obligations Portfolio also
 offers Class B and Class C Shares. You may purchase shares on any business
 day at their NAV next determined after receipt of an order in proper form by
 State Street Bank and Trust Company ("State Street") as agent for Goldman
 Sachs or certain authorized institutions ("Authorized Dealers"). No sales
 load is charged.
 
 Service Shares may be purchased through Goldman Sachs acting as a Service
 Organization or through Authorized Dealers. Class B and Class C Shares may
 be purchased through Goldman Sachs or through Authorized Dealers. Class B
 and Class C Shares will typically be issued only upon an exchange of Class B
 and Class C Shares of another equity or bond fund of the Goldman Sachs Trust
 (the "Trust") or to accounts that intend to systematically exchange such
 shares for Class B or Class C Shares of other Goldman Sachs Funds. If you do
 not specify in your instructions to the Funds which class of shares you wish
 to purchase, the Funds will assume that the instructions apply to Service
 Shares since, unlike Class B and Class C Shares, they are normally not sub-
 ject to any CDSC and have lower fees.
 
 In order to make an initial investment in a Fund, you must furnish to the
 Fund, Goldman Sachs, your Service Organization or your Authorized Dealer the
 information in the Account Application attached to this Prospectus.
 
 To Open an Account:
 
 .Complete the enclosed Account Application
 .Mail your payment and Account Application to:
  Your Authorized Dealer
  - Purchases by check or Federal Reserve draft should be made payable to
    your Authorized Dealer
  - Your Authorized Dealer is responsible for forwarding payment promptly
    (within three business days) to the Fund
 
  or
 
  Goldman Sachs Funds c/o National Financial Data Services ("NFDS"), P.O. Box
  419711, Kansas City, MO 64141-6711

  - Purchases by check or Federal Reserve draft should be made payable to
    Goldman Sachs Funds--(Name of Fund and Class of Shares)
  - NFDS will not accept a check drawn on a foreign bank or a third party
    check, cash, money orders, travelers checques or credit card checks
  - Federal funds wire, Automated Clearing House Network ("ACH") transfer or
    bank wires should be sent to State Street
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
 .Refuse to open an account if you fail to (i) provide a social security num-
  ber or other taxpayer identification number; or (ii) certify that such num-
  ber is correct (if required to do so under applicable law).
 .Reject any purchase order for any reason.
 .Modify or waive the minimum investment amounts.
 .Modify the manner in which shares are offered.
 .Modify the sales charge rate applicable to future purchases of Class B and
  Class C Shares.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Investment Adviser.

 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange shares is deter-
 mined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
 .NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (nor-
  mally 4:00 p.m. New York time). Fund shares will be priced on any day the
  New York Stock Exchange is open, except for days on which Chicago, Boston,
  or New York banks are closed for local holidays.
 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be granted to
  the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 A COMMON QUESTION ABOUT THE PURCHASE OF SERVICE SHARES
 
 
 What Is The Offering Price Of Service Shares?
 You may purchase Service Shares of the Funds at the next determined NAV
 without an initial sales charge. Service Shares are not subject to any CDSC.
 
 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS B SHARES
 
 
 What Is The Offering Price Of Class B Shares?
 You may purchase Class B Shares of the Prime Obligations Portfolio at the
 next determined NAV without an initial sales charge. However, Class B Shares
 redeemed within six years of purchase will be subject to a CDSC at the rates
 shown in the table below based on how long you held your shares.
 
                                                                              21

 No CDSC is imposed upon exchanges of Class B Shares between the Prime Obli-
 gation Portfolios and another Goldman Sachs Fund. However, shares acquired
 in an exchange will be subject to the CDSC to the same extent as if there
 had been no exchange.
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class B Shares, including the payment of compensation to Authorized Dealers.
 A commission equal to 4% of the amount invested is paid to Authorized Deal-
 ers.
 
 What Should I Know About The Automatic Conversion Of Class B Shares?
 Class B Shares of the Prime Obligations Portfolio will automatically convert
 into Service Shares of that Fund at the end of the calendar quarter that is
 eight years after the purchase date.
 
 If you acquire Class B Shares of the Fund by exchange from Class B Shares of
 another Goldman Sachs Fund, your Class B Shares will convert into Service
 Shares of the Fund based on the date of the initial purchase and the CDSC
 schedule of that purchase.
 
 If you acquire Class B Shares through reinvestment of distributions, your
 Class B Shares will convert into Service Shares based on the date of the
 initial purchase of the shares on which the distribution was paid.
 
 The conversion of Class B Shares to Service Shares will not occur at any
 time the Prime Obligations Portfolio is advised that such conversions may
 constitute taxable events for federal tax purposes, which the Fund believes
 is unlikely. If conversions do not occur as a result of possible taxability,
 Class B Shares would continue to be subject to higher expenses than Service
 Shares for an indeterminate period.

 A COMMON QUESTION ABOUT THE PURCHASE OF CLASS C SHARES
 
 
 What Is The Offering Price Of Class C Shares?
 You may purchase Class C Shares of the Prime Obligations Portfolio at the
 next determined NAV without paying an initial sales charge. However, if you
 redeem Class C Shares within 12 months of purchase, a CDSC of 1% will be
 deducted from the redemption proceeds; provided that in connection with pur-
 chases by pension and profit sharing plans, pension funds and othercompany-
 sponsored benefit plans, where all of the Class C Shares are redeemed within
 12 months of purchase, a CDSC of 1% may be imposed upon the plan sponsor or
 third party administrator.
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class C Shares, including the payment of compensation to Authorized Dealers.
 An amount equal to 1% of the amount invested is paid by the Distributor to
 Authorized Dealers.
 
 COMMON QUESTIONS APPLICABLE TO THE PURCHASE OF SERVICE, CLASS B AND CLASS C
 SHARES
 
 
 What Else Do I Need To Know About The CDSC On Class B Or C Shares?
 .No CDSC is charged on shares acquired from reinvested dividends or capital
  gains distributions.
 .When counting the number of months since a purchase of Class B or Class C
  Shares was made, all payments made during a month will be combined and con-
  sidered to have been made on the first day of that month.
 .To keep your CDSC as low as possible, each time you place a request to sell
  shares, the Funds will first sell any shares in your account that do not
  carry a CDSC and then the shares in your account that have been held the
  longest.
 
 In What Situations May The CDSC On Service, Class B Or Class C Shares Be
 Waived Or Reduced?
 The CDSC on Service, Class B or Class C Shares that are subject to a CDSC
 (i.e., because the Service Shares were acquired in an exchange transaction
 for shares of a Goldman Sachs Fund that were subject to a CDSC) may be
 waived or reduced if the redemption relates to:
 .Retirement distributions or loans to participants or beneficiaries from
  pension and profit sharing plans, pension funds and other company-sponsored
  benefit plans (each a "Retirement Plan");
 
                                                                              23
<PAGE>
 
 
 .The death or disability (as defined in Section 72(m)(7) of the Internal
  Revenue Code of 1986, as amended (the "Code")) of a participant or benefi-
  ciary in a Retirement Plan;
 .Hardship withdrawals by a participant or beneficiary in a Retirement Plan;
 .Satisfying the minimum distribution requirements of the Code;
 .Establishing "substantially equal periodic payments" as described under
  Section 72(t)(2) of the Code;
 .The separation from service by a participant or beneficiary in a Retirement
  Plan;
 .The death or disability (as defined in Section 72(m)(7) of the Code) of a
  shareholder if the redemption is made within one year of the event;
 .Excess contributions distributed from a Retirement Plan;
 .Distributions from a qualified Retirement Plan invested in the Goldman
  Sachs Funds which are being rolled over to a Goldman Sachs IRA; or
 .Redemption proceeds which are to be reinvested in accounts or non-regis-
  tered products over which GSAM or its advisory affiliates have investment
  discretion.
 
 In addition, Service, Class B and Class C Shares subject to a systematic
 withdrawal plan may be redeemed without a CDSC. The Funds reserve the right
 to limit such redemptions, on an annual basis, to 10% of the value of your
 Service Shares and 12% each of the value of your Class B and C Shares.
 
 What Other Attributes of Service, Class B Or Class C Shares Should I Know
 About?
 .Service Shares. Service Shares are normally not subject to any initial
  sales charge or CDSC. However, Service Shares are subject to a service fee
  at the annual rate of 0.40% of a Fund's average daily net assets attribut-
  able to Service Shares.
 .Class B Shares. Class B Shares are subject to a CDSC but not an initial
  sales charge. By not paying a front-end sales charge, your entire invest-
  ment in Class B Shares is available to work for you from the time you make
  your initial investment. However, the distribution fee of up to 0.75% and
  service fee of up to 0.25% paid by Class B Shares will cause your Class B
  Shares (until conversion to Service Shares) to have a higher expense ratio,
  and thus lower performance and dividend payments, than Service Shares.
  A maximum purchase limitation of $250,000 in the aggregate normally
  applies to Class B Shares.
 .Class C Shares. Class C Shares are also subject to a CDSC but not an ini-
  tial sales charge. By not paying a front-end sales charge, your entire
  investment in Class C Shares is available to work for you from the time you
  make your initial investment. However, the distribution fee of 0.75% and
  service fee of 0.25%

  paid by Class C Shares will cause your Class C Shares to have a higher
  expense ratio, and thus lower performance and dividend payments, than Serv-
  ice Shares (or Class B Shares after conversion to Service Shares).
  Although Class C Shares are subject to a CDSC for only 12 months, Class C
  Shares do not have the conversion feature applicable to Class B Shares and
  your investment will therefore pay higher distribution fees indefinitely.
  A maximum purchase limitation of $1,000,000 in the aggregate normally
  applies to purchases of Class C Shares.
 
 Note: Authorized Dealers may receive different compensation for selling
 Service, Class B or Class C Shares.
 
 In addition to Service, Class B and Class C Shares, each Fund also offers
 other classes of shares to investors. These other share classes are subject
 to different fees and expenses (which affect performance), have different
 minimum investment requirements and are entitled to different services.
 Information regarding these other share classes may be obtained from your
 sales representative or from Goldman Sachs by calling the number on the back
 cover of this Prospectus.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Generally, each Fund will redeem its shares upon
 request on any business day at their NAV next determined after receipt of
 such request in proper form, subject to any applicable CDSC. You may request
 that redemption proceeds be sent to you by check or by wire (if the wire
 instructions are on record). Redemptions may be requested in writing or by
 telephone.
 
                                                                              25

 When Do I Need A Signature Guarantee To Redeem Shares?
 A signature guarantee is required if:
 .You would like the redemption proceeds sent to an address that is not your
  address of record; or
 .You would like to change the bank designated on your Account Application.
 
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federalsavings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.
 Additional documentation may be required for executors, trustees or corpora-
 tions or when deemed appropriate by the Transfer Agent.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 The Trust may accept telephone redemption requests from any person identify-
 ing himself or herself as the owner of an account or the owner's registered
 representative where the

 owner has not declined in writing to use this service. Thus, you risk possi-
 ble losses if a telephone redemption is not authorized by you.
 
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs and NFDS employs reasonable procedures
 specified by the Trust to confirm that such instructions are genuine. If
 reasonable procedures are not employed, the Trust may be liable for any loss
 due to unauthorized or fraudulent transactions. The following general poli-
 cies are currently in effect:
 .All telephone requests are recorded.
 .Proceeds of telephone redemption requests will be sent only to your address
  of record or authorized bank account designated on your Account Application
  (unless you provide written instructions and a signature guarantee, indi-
  cating another address or account) and exchanges of shares normally will be
  made only to an identically registered account.
 .Telephone redemptions will not be accepted during the 30-day period follow-
  ing any change in your address of record.
 .The telephone redemption option does not apply to shares held in a "street
  name" account. "Street name" accounts are accounts maintained and serviced
  by your Authorized Dealer. If your account is held in "street name," you
  should contact your registered representative of record, who may make tele-
  phone redemptions on your behalf.
 .The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 When Will Redemption Proceeds Be Wired Or Mailed?
 Redemption proceeds will normally be wired or mailed to the recordholder of
 shares as follows:

 .Although redemption proceeds will normally be wired or mailed as described
  above, each Fund reserves the right to pay redemption proceeds up to three
  business days following receipt of a properly executed wire transfer
  redemption request. If you are selling shares you recently paid for by
  check, the Fund will pay you when your check has cleared, which may take up
  to 15 days. If the Federal Reserve Bank is closed on the day that the
  redemption proceeds would ordinarily be wired, wiring the redemption pro-
  ceeds may be delayed one additional business day.
 .A transaction fee of $7.50 may be charged for payments of redemption pro-
  ceeds by wire. Your bank may also charge wiring fees. You should contact
  your bank directly to learn whether it charges such fees.
 .To change the bank designated on your Account Application, you must send
  written instructions (with your signature guaranteed) to the Transfer
  Agent.
 .Neither the Trust, Goldman Sachs nor any Authorized Dealer assumes any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
 
 What Should I Know About The Check Redemption Privilege (Service Shares
 Only)?
 You may elect to have a special account with State Street for the purpose of
 redeeming shares from your account by check. The following general policies
 govern the check redemption privilege:
 .You will be provided with a supply of checks when State Street receives a
  completed signature card and authorization form. Checks drawn on the
  account may be payable to the order of any person in any amount over $500,
  but cannot be certified.
 .The payee of the check may cash or deposit it just like any other check
  drawn on a bank.
 .When the check is presented to State Street for payment, a sufficient num-
  ber of full or fractional Service Shares will be redeemed to cover the
  amount of the check.
 .Canceled checks will be returned to you by State Street.
 .The check redemption privilege allows you to receive the dividends declared
  on the Service Shares that are to be redeemed until the check is actually
  processed. Because of this feature, accounts may not be completely liqui-
  dated by check.
 .If the amount of the check is greater than the value of the Service Shares
  held in your account, the check will be returned unpaid. In this case, you
  may be subject to extra charges.
 .The Trust reserves the right to limit the availability of, modify or termi-
  nate the check redemption privilege at any time with respect to any or all
  shareholders.

 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 .Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 
 The Trust reserves the right to:
 .Redeem the shares of any account whose balance falls below the minimum as a
  result of redemption. The Fund will give 60 days' prior written notice to
  allow you to purchase sufficient additional shares of the Fund in order to
  avoid such redemption.
 .Redeem the shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
 .Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange Service Shares of each Fund and Class B and C Shares of the
 Prime Obligations Portfolio for shares of the same class or an equivalent
 class of any other Goldman Sachs Fund. The exchange privilege may be materi-
 ally modified or withdrawn at any time upon 60 days' written notice to you.

 You should keep in mind the following factors when making or considering an
 exchange:
 .You should obtain and carefully read the prospectus of the Fund you are
  acquiring before making an exchange.
 .Six free exchanges are allowed in each 12 month period.
 .A $12.50 fee may be charged for each subsequent exchange.
 .There is no charge for exchanges made pursuant to the Automatic Exchange
  Program.
 .Exchanges of Class B and Class C Shares will be made at NAV and will be
  subject to the CDSC of the original shares held. For purposes of determin-
  ing the amount of the applicable CDSC, the length of time you have owned
  the shares will be measured from the date you acquired the original shares
  subject to a CDSC and will not be affected by subsequent exchange.
 .Exchanges of Service Shares from each Fund will be made into the relevant
  Goldman Sachs Fund at the public offering price, which may include a sales
  charge, unless a sales charge has previously been paid on the investment
  represented by the exchanged shares (i.e., the shares to be exchanged were
  originally issued in exchange for shares on which a sales charge was paid),
  in which case the exchange will be made at NAV. Service Shares acquired in
  an exchange transaction for shares of a Goldman Sachs Fund will be subject
  to the CDSC, if any, of the shares originally held.
 .All exchanges which represent an initial investment in a Fund must satisfy
  the minimum initial investment requirements of that Fund. The minimum ini-
  tial exchange is $5,000 or the full account share balance, whichever is
  less.
 .Exchanges are available only in states where exchanges may be legally made.
 .It may be difficult to make telephone exchanges in times of drastic eco-
  nomic or market conditions.
 .Goldman Sachs and NFDS may use reasonable procedures described under "What
  Do I Need To Know About Telephone Redemption Requests?" in an effort to
  prevent unauthorized or fraudulent telephone exchange requests.
 .Telephone exchanges normally will be made only to an identically registered
  account. Shares may be exchanged among accounts with different names,
  addresses and social security or other taxpayer identification numbers only
  if the exchange instructions are in writing and accompanied by a signature
  guarantee.
 
 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.

 .No initial sales charge is imposed.
 .Sales subject to a CDSC acquired under this program may be subject to a
  CDSC at the time of redemption from the Fund into which the exchange is
  made depending upon the date and value of your original purchase.
 .Automatic exchanges are made monthly on the 15th day of each month or the
  first business day thereafter.
 .Minimum dollar amount: $50 per month.
 
 Do I Have Any Reinvestment Privileges With Respect to Class B or
 Class C Shares?
 You may redeem Class B or Class C Shares of a Fund and reinvest a portion or
 all of the redemption proceeds (plus any additional amounts needed to round
 off purchases to the nearest full share). To be eligible for this privilege,
 you must hold the shares you want to redeem for at least 30 days and must
 reinvest the share proceeds within 90 days after you redeem. You may rein-
 vest as follows:
 .If you redeem Class B Shares of the Prime Obligations Portfolio, you may
  reinvest any or all of the redemption proceeds (plus that amount necessary
  to acquire a fractional share to round off the purchase to the nearest full
  share) in Service Shares of Prime Obligations Portfolio and Tax-Exempt
  Diversified Portfolio or Class A Shares of any Goldman Sachs Fund at NAV.
  The amount of the CDSC paid upon redemption will not be credited to your
  account.
 .If you redeem Class C Shares of the Prime Obligations Portfolio, you may
  reinvest any or all of the redemption proceeds (plus that amount necessary
  to acquire a fractional share to round off the purchase to the nearest full
  share) in Class C Shares of the Prime Obligations Portfolio or Class C
  Shares of any other Goldman Sachs Fund.
 
                                                                              31
<PAGE>
 
 
 .You should obtain and read the applicable prospectuses before investing in
  any other Funds.
 .If you redeem Class C Shares, pay a CDSC upon redemption and reinvest in
  Class C Shares subject to the conditions set forth above, your account will
  be credited with the amount of the CDSC previously charged, and the rein-
  vested shares will continue to be subject to a CDSC. In this case, the
  holding period of the Class C Shares acquired through reinvestment for pur-
  poses of computing the CDSC payable upon a subsequent redemption will
  include the holding period of the redeemed shares.
 .The reinvestment privilege may be exercised once annually by a shareholder
  upon written request, except that this time limit does not apply to trans-
  actions the sole purpose of which is to reinvest the proceeds at NAV in a
  tax-sheltered retirement plan.
 .You may be subject to tax as a result of a redemption. You should consult
  your tax adviser concerning the tax consequences of a redemption and rein-
  vestment.
 
 Can I Have Automatic Withdrawals Made On A Regular Basis?
 You may draw on your account systematically via check or ACH transfer in any
 amount of $50 or more.
 .It is normally undesirable to maintain a systematic withdrawal plan at the
  same time that you are purchasing additional Class B or Class C Shares
  because of the imposition of a CDSC on your redemptions of Class B or Class
  C Shares.
 .You must have a minimum balance of $5,000 in a Fund.
 .Checks are mailed on or about the 25th day of each month.
 .Each systematic withdrawal is a redemption and therefore a taxable transac-
  tion.
 .The CDSC applicable to Class B or Class C Shares redeemed under the system-
  atic withdrawal plan may be waived.
 
 What Types of Reports Will I Be Sent Regarding Investments in Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-526-7384.
 
 What Should I Know When I Purchase Shares Through An Authorized Dealer?
 Authorized Dealers and other financial intermediaries may provide varying
 arrangements for their clients to purchase and redeem Fund shares. They may
 charge additional fees not described in this Prospectus to their customers
 for such services.

                                                               SHAREHOLDER GUIDE
 
 
 If shares of a Fund are held in a "street name" account with an Authorized
 Dealer, all recordkeeping, transaction processing and payments of distribu-
 tions relating to your account will be performed by the Authorized Dealer,
 and not by the Fund and its Transfer Agent. Since the Funds will have no
 record of your transactions, you should contact the Authorized Dealer to
 purchase, redeem or exchange shares, to make changes in or give instructions
 concerning your account or to obtain information about your account. The
 transfer of shares in a "street name" account to an account with another
 dealer or to an account directly with the Fund involves special procedures
 and will require you to obtain historical purchase information about the
 shares in the account from the Authorized Dealer.
 
 Authorized Dealers and other financial intermediaries may be authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and if approved by the Trust, to
 designate other intermediaries to accept such orders. In these cases:
 .A Fund will be deemed to have received an order that is in proper form by
  or on behalf of a customer when the order is accepted by an Authorized
  Dealer or intermediary on a business day, and the order will be priced at
  the Fund's NAV per share (adjusted for any applicable sales charge) next
  determined after such acceptance.
 .Authorized Dealers and intermediaries are responsible for transmitting
  accepted orders to the Funds within the time period agreed upon by them.
 
 You should contact your Authorized Dealer or intermediary directly to learn
 whether it is authorized to accept orders for the Trust.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Authorized Dealers and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Autho-
 rized Dealers depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses.
 
                                                                              33

 DISTRIBUTION SERVICES AND FEES
 
 
 What Are The Different Distribution And Service Fees Paid By Service, Class
 B and Class C Shares?
 The Trust has adopted plans (each a "Plan") under which Service, Class B and
 Class C Shares bear service fees and (in the case of Class B and Class C
 Shares) distribution fees paid to Service Organizations and Goldman Sachs.
 If the fees received by Goldman Sachs pursuant to the Plans exceed its
 expenses, Goldman Sachs may realize a profit from these arrangements.
 Goldman Sachs pays the distribution and service fees on a quarterly basis.
 
 Under the Plan for Service Shares, Service Organizations agree to provide
 services in connection with their customers' investments in Service Shares,
 such as:
 .Acting, directly or through an agent, as the sole shareholder of record
 .Maintaining account record for customers
 .Processing orders to purchase, redeem or exchange shares for customers
 .Responding to inquiries from prospective and existing shareholders
 .Assisting customers with investment procedures
 
 For their services, Service Organizations are entitled to receive payment
 from the Trust of up to 0.40% (on an annualized basis) of the average daily
 net assets of the Service Shares of the Funds, which are attributable to or
 held in the name of a Service Organization for its customers. In addition,
 GSAM, at its own expense, may pay a Service Organization up to 10% of the
 average daily net assets of the Service Shares of a Fund, which are attrib-
 utable to or held in the name of the Service Organization for its customers.
 Such compensation does not represent an additional expense to a Fund or its
 shareholders, since it will be paid from the assets of GSAM.
 
 Under the Plans for Class B and Class C Shares, Goldman Sachs is entitled to
 a monthly fee from each Fund for distribution services equal, on an annual
 basis, to 0.75% of a Fund's average daily net assets attributed to Class B
 and Class C Shares. Because these fees are paid out of the Fund's assets on
 an ongoing basis, over time, these fees will increase the cost of your
 investment and may cost you more than paying other types of sales charges.
 
 The distribution fees are subject to the requirements of Rule 12b-1 under
 the Act, and may be used (among other things) for:
 .Compensation paid to and expenses incurred by Authorized Dealers, Goldman
  Sachs and their respective officers, employees and sales representatives;
 .Commissions paid to Authorized Dealers;
 .Allocable overhead;

 .Telephone and travel expenses;
 .Interest and other costs associated with the financing of such compensation
  and expenses;
 .Printing of prospectuses for prospective shareholders;
 .Preparation and distribution of sales literature or advertising of any
  type; and
 .All other expenses incurred in connection with activities primarily
  intended to result in the sale of Class B and Class C Shares.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.75% distribution fee as an ongoing commission to Authorized Dealers
 after the shares have been held for one year.
 
 PERSONAL ACCOUNT MAINTENANCE SERVICES AND FEES
 
 Under the Plans for Class B and Class C Shares, Goldman Sachs is also enti-
 tled to receive a separate fee equal on an annual basis to 0.25% of each
 Fund's average daily net assets attributed to Class B or Class C Shares.
 This fee is for personal and account maintenance services, and may be used
 to make payments to Goldman Sachs, Authorized Dealers and their officers,
 sales representatives and employees for responding to inquiries of, and fur-
 nishing assistance to, shareholders regarding ownership of their shares or
 their accounts or similar services not otherwise provided on behalf of the
 Funds. If the fees received by Goldman Sachs pursuant to the Plans exceed
 its expenses, Goldman Sachs may realize a profit from this arrangement.
 
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.25% ongoing service fee to Authorized Dealers after the shares have
 been held for one year.

Taxation
 
Each Fund intends to qualify as a regulated investment company for federal tax
purposes, and to distribute to shareholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Diversified Portfolio, Fund dividends will generally
be taxable to you as ordinary income (unless your investment is in an IRA or
other tax-advantaged account) regardless of whether you reinvest in additional
shares or take them as cash. The Tax-Exempt Diversified Portfolio expects gen-
erally to distribute "exempt-interest dividends," which will be tax-exempt
income for federal income tax purposes. The tax status and amounts of the divi-
dends for each calendar year will be detailed in your annual tax statement from
the Funds.
 
Dividends and distributions from each Fund will generally be taxable to you in
the tax year in which they are paid, with one exception. Dividends and distri-
butions declared by a Fund in October, November or December and paid in January
are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry shares of the
Tax-Exempt Diversified Portfolio generally will not be deductible for income
tax purposes.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Diversified Portfolio may be an item of tax preference for purposes
of determining your AMT liability. Exempt-interest dividends will also be con-
sidered along with other adjusted gross income in determining whether any
social security or railroad retirement payments received by you are subject to
federal income taxes.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from any Fund (including the Tax-Exempt Diver-
sified Portfolio) or on the value of the shares held by you. More tax informa-
tion is provided in the Additional Statement. You should also consult your own
tax adviser for information regarding all tax consequences applicable to your
investments in the Funds.

Appendix A
Additional Information on Portfolio Risks, Securities and Techniques
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Funds, including their associated
risks. Additional information is provided in the Additional Statement, which is
available upon request. Among other things, the Additional Statement describes
certain fundamental policies and investment restrictions that cannot be changed
without shareholder approval. You should note, however, that all policies not
specifically designated as fundamental are non-fundamental and may be changed
without shareholder approval. If there is a change in a Fund's investment
objective, you should consider whether that Fund remains an appropriate invest-
ment in light of your then current financial position and needs.
 
U.S. Treasury Obligations and U.S. Government Securities and Related Custodial
Receipts. U.S. Treasury Obligations include securities issued or guaranteed by
the U.S. Treasury ("U.S. Treasury Obligations"). Payment of principal and
interest on these obligations is backed by the full faith and credit of the
U.S. government. U.S. Treasury Obligations include, among other things, the
separately traded principal and interest components of securities guaranteed or
issued by the U.S. Treasury if such components are traded independently under
the Separate Trading of Registered Interest and Principal of Securities program
("STRIPS").
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury Obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.
 
                                                                              37
<PAGE>
 
 
 
U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Each Fund may also acquire U.S. Government Securities in the form of custodial
receipts. Custodial receipts evidence ownership of future interest payments,
principal payments or both on notes or bonds issued or guaranteed as to princi-
pal and interest by the U.S. government, its agencies, instrumentalities,
political subdivisions or authorities. For certain securities law purposes,
custodial receipts are not considered obligations of the U.S. government.
 
Bank Obligations. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. A Fund may invest in obligations issued or backed by
U.S. banks when a bank has more than $1 billion in total assets at the time of
purchase or is a branch or subsidiary of such a bank. Bank obligations may be
general obligations of the parent bank or may be limited to the issuing branch
by the terms of the specific obligation or by government regulation.
 
Commercial Paper. A Fund may invest in commercial paper, including variable
amount master demand notes and asset-backed commerical paper. Commerical paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, finance companies and other issuers.
The commercial paper purchased by a Fund consists of direct U.S. dollar-denomi-
nated obligations of domestic or, in the case of a certain Funds, foreign
issuers.
 
Short-Term Obligations. A Fund may invest in other short-term obligations,
including short-term funding agreements payable in U.S. dollars and issued or
guaranteed by U.S. corporations, foreign corporations or other entities. A
funding agreement is a contract between an issuer and a purchaser that obli-
gates the issuer to pay a guaranteed rate of interest on a principal sum depos-
ited by the purchaser. Funding agreements will also guarantee a stream of pay-
ments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and guaran-
teed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Fund will be regarded as
illiquid.
 
Asset-Backed and Receivables-Backed Securities. The Prime Obligations Portfolio
may invest in asset-backed and receivables-backed securities, whose principal
and interest payments are collateralized by pools of assets such as auto loans,
credit card receivables, leases, installment contracts and personal property.
Asset-backed and receivables-backed securities are often subject to more rapid
repayment than their stated maturity date would indicate as a result of the
pass-through of prepayments of

<PAGE>
 
                                                                      APPENDIX A
 
principal on the underlying loans. During periods of declining interest rates,
prepayment of loans underlying asset-backed and receivables-backed securities
can be expected to accelerate. Accordingly, a Fund's ability to maintain posi-
tions in such securities will be affected by reductions in the principal amount
of such securities resulting from prepayments, and its ability to reinvest the
returns of principal at comparable yields is subject to generally prevailing
interest rates at that time. In addition, securities that are backed by credit
card, automobile and similar types of receivables generally do not have the
benefit of a security interest in collateral that is comparable in quality to
mortgage assets. There is the possibility that, in some cases, recoveries on
repossessed collateral may not be available to support payments on these
securities. In the event of a default, the Fund may suffer a loss if it cannot
sell collateral quickly and receive the amount it is owed.
 
Repurchase Agreements. Each Fund may enter into repurchase agreements with pri-
mary dealers in U.S. Government Securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund are less than the repurchase price and the Fund's
cost associated with delay and enforcement of the repurchase agreement. In
addition, in the event of bankruptcy of the seller, a Fund could suffer addi-
tional losses if a court determines that the Fund's interest in the collateral
is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, each Fund, together with other registered investment
companies having advisory agreements with the Investment Adviser or any of its
affiliates, may transfer uninvested cash balances into a single joint account,
the daily aggregate balance of which will be invested in one or more repurchase
agreements.
 
Municipal Obligations. The Funds may invest in municipal obligations. Municipal
obligations are issued by or on behalf of states, territories and possessions
of the United States and their political subdivisions, agencies, authorities
and instrumentalities, and the District of Columbia. Municipal obligations may
include fixed rate notes and similar debt instruments; variable and floating
rate demand instruments; tax-exempt commercial paper; municipal bonds; and
unrated notes, paper, bonds or other instruments.
 
Municipal Notes and Bonds. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
 
                                                                              39
<PAGE>
 
 
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
Tender Option Bonds. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Fund's average portfolio maturity. There is a risk that a Fund will not be con-
sidered the owner of a tender option bond for federal income tax purposes, and
thus will not be entitled to treat such interest as exempt from federal income
tax. Certain tender option bonds may be illiquid or may become illiquid as a
result of a credit rating downgrade, a payment default or a disqualification
from tax-exempt status.
 
Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which include a demand feature that permits the
holder to sell the RAWs to a bank or other financial institution at a purchase
price equal to par plus accrued interest on each interest rate reset date.

                                                                      APPENDIX A
 
 
Industrial Development Bonds. The Funds may invest in industrial development
bonds (private activity bonds). Industrial development bonds are a specific
type of revenue bond backed by the credit and security of a private user, the
interest from which would be an item of tax preference when distributed by a
Fund as "exempt-interest dividends" to shareholders under the AMT.
 
Other Municipal Obligation Policies. The Tax-Exempt Diversified Fund may invest
25% or more of the value of its total assets in municipal obligations which are
related in such a way that an economic, business or political development or
change affecting one municipal obligation would also affect the other municipal
obligation. For example, the Fund may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of the Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political developments affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality of these banks and financial institutions could,
therefore, cause a loss to a Fund that invests in municipal obligations. Let-
ters of credit and other obligations of foreign banks and financial institu-
tions may involve risks in addition to those of domestic obligations because of
less publicly available financial and other information, less securities regu-
lation, potential imposition of foreign withholding and other taxes, war,
expropriation or other adverse governmental actions. Foreign banks and their
foreign branches are not regulated by U.S. banking authorities, and generally
are not bound by the accounting, auditing and financial reporting standards
applicable to U.S. banks. In addition, the Funds may acquire securities in the
form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.
 
Floating and Variable Rate Obligations. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Fund may consider the
 
                                                                              41
<PAGE>
 
 
maturity of a variable or floating rate obligation to be shorter than its ulti-
mate stated maturity if the obligation is a U.S. Treasury Obligation or U.S.
Government Security, if the obligation has a remaining maturity of 397 calendar
days or less, or if the obligation has a demand feature that permits the Fund
to receive payment at any time or at specified intervals not exceeding 397 cal-
endar days. The issuers or financial intermediaries providing demand features
may support their ability to purchase the obligations by obtaining credit with
liquidity supports. These may include lines of credit, which are conditional
commitments to lend and letters of credit, which will ordinarily be irrevoca-
ble, both of which may be issued by domestic banks or foreign banks which have
a branch, agency or subsidiary in the United States. A Fund may purchase vari-
able or floating rate obligations from the issuers or may purchase certificates
of participation, a type of floating or variable rate obligation, which are
interests in a pool of debt obligations held by a bank or other financial
institution.
 
When-Issued Securities and Forward Commitments. The Funds may purchase when-
issued securities and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. When-issued securities
are securities that have been authorized, but not yet issued. When-issued secu-
rities are purchased in order to secure what is considered to be an advanta-
geous price and yield to a Fund at the time of entering into the transaction. A
forward commitment involves entering into a contract to purchase or sell secu-
rities for a fixed price at a future date beyond the customary settlement peri-
od.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Fund will generally purchase
securities on a when-issued or forward commitment basis with the intention of
acquiring securities for its portfolio, a Fund may dispose of when-issued secu-
rities or forward commitments prior to settlement if the Investment Adviser
deems it appropriate.
 
Other Investment Companies. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Act. These limitations
include a prohibition on any Fund acquiring more than 3% of the voting shares
of any other investment company, and a prohibition on investing more than 5% of
a Fund's total assets in securities of any one investment company or more than
10% of its total assets in securities of all investment companies. A Fund will
indirectly bear its proportionate share of any management fees and other
expenses paid by such other investment companies. Such other investment compa-
nies will have investment objectives, policies and restrictions substantially
similar to those of the acquiring Fund and will be subject to substantially the
same risks.

Illiquid Securities. Each Fund may invest up to 10% of its net assets in illiq-
uid securities which cannot be disposed of in seven days in the ordinary course
of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
Borrowings. Each Fund may borrow up to 33- 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
Downgraded Securities. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.

Financial Highlights
 
 The financial highlights tables are intended to help you understand a Fund's
 financial performance for the past five years (or less if the Fund has been
 in operation for less than five years). Certain information reflects finan-
 cial results for a single Fund share. The total returns in the table repre-
 sent the rate that an investor would have earned or lost on an investment in
 a Fund (assuming reinvestment of all dividends and distributions). This
 information has been audited by Arthur Andersen LLP, whose report, along
 with a Fund's financial statements, is included in the Fund's annual report
 (available upon request without charge).

General Investment Management Approach
 
 
 The Government Portfolio and Tax-Exempt Diversified Portfolio (the "Portfo-
 lios") are portfolios of Goldman Sachs Trust (the "Trust"), an open-end,
 management investment company (a "mutual fund") which includes the Goldman
 Sachs-Institutional Liquid Assets Portfolios. This Prospectus relates to the
 offering of ILA Service Units of beneficial interest of each Portfolio
 ("Oakmark Units") through Harris Associates, L.P. ("Harris Associates") in
 its capacity as a Service Organization for the Portfolios.
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment Adviser to the
 Portfolios. GSAM is referred to in this Prospectus as the "Investment Advis-
 er." Harris Associates or its designee will act as nominee and record holder
 of the Oakmark Units. You should be aware that Oakmark Units of the Portfo-
 lios may be purchased only through Harris Associates or its designee. Harris
 Associates is not the distributor of the Portfolios.
 
 Goldman Sachs' Money Market Investment Philosophy:
 The Portfolios are managed to seek preservation of capital, daily liquidity
 and maximum current income. With each Portfolio, the Investment Adviser fol-
 lows a conservative, risk-managed investment process that seeks to:
 .Manage credit risk
 .Manage interest rate risk
 .Manage liquidity
 
 Since 1981, the Investment Adviser has actively managed the Goldman Sachs
 Money Market Funds to provide investors with the greatest possible preserva-
 tion of principal and income potential.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 1.Managing Credit Risk
 
 The Investment Adviser's process for managing risk emphasizes:
 .Intensive research--The Credit Department, a separate operating entity of
  Goldman Sachs, approves all credits for the Portfolios. Sources for their
  analysis include third-party inputs, such as financial statements and media
 
                                                                               1
<PAGE>
 
 
  sources, ratings releases and company meetings, as well as the Investment
  Research, Legal and Compliance departments of Goldman Sachs.
 .Timely updates--A Credit Department-approved list of securities is
  continuously communicated on a "real-time" basis to the portfolio
  management team via computer link.
 
 The Result: An "approved" list of high-quality credits--The Investment
 Adviser's portfolio management team uses this approved list to construct
 portfolios which offer the best available risk-return tradeoff within the
 "approved" credit universe.
 
 2.Managing Interest Rate Risk
 
 Three main steps are followed in seeking to manage interest rate risk:
 .Establish weighted average maturity (WAM) target--WAM (the weighted average
  time until the yield of a portfolio reflects any changes in the current
  interest rate environment) is constantly revisited and adjusted as market
  conditions change. An overall strategy is developed by the portfolio
  management team based on insights gained from weekly meetings with both
  Goldman Sachs economists and economists from outside the firm.
 .Implement optimum portfolio structure--Proprietary models that seek the
  optimum balance of risk and return, in conjunction with the Investment
  Adviser's analysis of factors such as market events, short-term interest
  rates and each Portfolio's asset volatility, are used to identify the most
  effective portfolio structure.
 .Conduct rigorous analysis of new securities--The Investment Adviser's five-
  step process includes legal, credit, historical index and liquidity
  analysis, as well as price stress testing to determine suitability for
  money market mutual funds.
 
 3. Managing Liquidity
 
 Factors that the Investment Adviser's portfolio managers continuously moni-
 tor and that affect liquidity of a money market portfolio include:
 .Each Portfolio's clients and factors that influence their asset volatility;
 .Technical events that influence the trading range of federal funds and
  other short-term fixed-income markets; and
 .Bid-ask spreads associated with securities in the portfolios.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
 
 Benchmarks for the Portfolios are the IBC Financial Data Universal Averages.
 Each Portfolio tracks the IBC Index which best corresponds to the Portfo-
 lio's eligible investments.
 
- --------------------------------------------------------------------------------
 
 .The Portfolios: Each Portfolio's securities are valued by the amortized cost
  method as permitted by Rule 2a-7 under the Investment Company Act of 1940,
  as amended (the "Act"). Under Rule 2a-7, each Portfolio may invest only in
  U.S. dollar-denominated securities that are determined to present minimal
  credit risk and meet certain other criteria, including conditions relating
  to maturity, diversification and credit quality. These operating policies
  may be more restrictive than the fundamental policies set forth in the
  Statement of Additional Information (the "Additional Statement").
 .The Investors: The Portfolios are designed for investors seeking a high rate
  of return, a stable net asset value ("NAV") and convenient liquidation priv-
  ileges. The Portfolios are particularly suitable for banks, corporations and
  other financial institutions that seek investment of short-term funds for
  their own accounts or for the accounts of their customers.
 .NAV: Each Portfolio seeks to maintain a stable NAV of $1.00 per unit.
 .Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
 .Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
 .Investment Restrictions: Each Portfolio is subject to certain investment
  restrictions that are described in detail under "Investment Restrictions" in
  the Additional Statement. Fundamental investment restrictions and the
  investment objective of a Portfolio cannot be changed without approval of a
  majority of the outstanding units of that Portfolio. All investment policies
  not specifically designated as fundamental are non-fundamental and may be
  changed without unitholder approval.
 .Diversification: Diversification can help a Portfolio reduce the risks of
  investing. In accordance with current regulations of the Securities and
  Exchange Commission (the "SEC"), each Portfolio may not invest more than 5%
  of the value of its total assets at the time of purchase in the securities
  of any single issuer with the exception that the Portfolios may invest up to
  25% of their total assets in the securities of a single issuer for up to
  three business days. These limitations do not apply to cash, certain repur-
  chase agreements, U.S. Government Securities (as defined in Appendix A) or
  securities of other investment companies. In addition, securities subject to
  certain unconditional guarantees and securities that are not "First Tier
  Securities" as defined by the SEC are subject to different diversification
  requirements as described in the Additional Statement.

Portfolio Investment Objectives and Strategies
 
 INVESTMENT OBJECTIVES
 
 Government Portfolio:
 
 The Government Portfolio seeks to maximize current income to the extent con-
 sistent with the preservation of capital and the maintenance of liquidity by
 investing exclusively in high quality money market instruments.
 
 Tax-Exempt Diversified Portfolio:
 
 The Tax-Exempt Diversified Portfolio seeks to provide shareholders, to the
 extent consistent with the preservation of capital and prescribed portfolio
 standards, with a high level of income exempt from federal income tax by
 investing primarily in municipal instruments.
 
 The Tax-Exempt Diversified Portfolio pursues its investment objective by
 investing in securities issued by or on behalf of states, territories, and
 possessions of the United States and their political subdivisions, agencies,
 authorities and instrumentalities, and the District of Columbia, the inter-
 est from which, if any, is in the opinion of bond counsel excluded from
 gross income for federal income tax purposes, and not an item of tax prefer-
 ence under the federal alternative minimum tax ("AMT").

 Note: See Appendix A for a description of, and certain criteria applicable

  1 Issued or guaranteed by the U.S. Treasury.
  2 To the extent permitted by Rule 2a-7, securities without short-term
    ratings may be purchased if they are deemed to be of comparable quality
    to First Tier Securities, or to the extent that the Tax-Exempt
    Diversified Portfolio may purchase Second Tier Securities, comparable in
    quality to Second Tier Securities. In addition, a Portfolio holding a
    security supported by a guarantee or demand feature may
 
                                                                               5
<PAGE>
 
 
  rely on the credit quality of the guarantee or demand feature in
  determining the credit quality of the investment.
  3 Ordinarily expect that 100% of the Portfolio's portfolio securities will
    be invested in municipal obligations, but the Portfolio may, for
    temporary defensive purposes, hold cash or invest in short-term taxable
    securities.
  4 See "Taxation" below for an explanation of the tax consequences
    summarized in the table above.
  5 First Tier Securities are (a) rated in the highest short-term rating
    category by at least two NRSROs, or if only one NRSRO has assigned a
    rating, by that NRSRO; or (b) issued or guaranteed by, or otherwise allow
    a Portfolio under certain conditions to demand payment from, an entity
    with such ratings. U.S. Government Securities are considered First Tier
    Securities.
  6 Taxable in many states except for distributions from U.S. Treasury
    Obligation interest income and certain U.S. Government Securities
    interest income.
  7 Second Tier Securities are (a) rated in the top two short-term rating
    categories by at least two NRSROs, or if only one NRSRO has assigned a
    rating, by that NRSRO; or (b) issued or guaranteed by, or otherwise allow
    a Portfolio under certain conditions to demand payment from, an entity
    with such ratings.
 10 Taxable except for distributions from interest on obligations of an
    investor's state of residence in certain states.
 11 If such policy should change, private activity bonds subject to AMT would
    not exceed 20% of the Portfolio's net assets under normal market
    conditions.
 12 No more than 25% of the value of the Portfolio's total assets may be
    invested in industrial development bonds or similar obligations where the
    non-governmental entities supplying the revenues from which such bonds or
    obligations are to be paid are in the same industry.

Principal Risks of the Portfolios
 
Loss of money is a risk of investing in each Portfolio. An investment in a
Portfolio is not a deposit of any bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency. The fol-
lowing summarizes important risks that apply to the Portfolios and may result
in a loss of your investment. None of the Portfolios should be relied upon as a
complete investment program. There can be no assurance that a Portfolio will
achieve its investment objective.

</TABLE>
 
Risks that apply to both Portfolios:
 
 .NAV Risk--The risk that a Portfolio will not be able to maintain a NAV per
 unit of $1.00 at all times.
 .Interest Rate Risk--The risk that during periods of rising interest rates, a
 Portfolio's yield (and the market value of its securities) will tend to be
 lower than prevailing market rates; in periods of falling interest rates, a
 Portfolio's yield will tend to be higher.
 .Credit/Default Risk--The risk that an issuer or guarantor of a security, or a
 bank or other financial institution that has entered into a repurchase agree-
 ment, may default on its payment obligations. In addition, with respect to the
 Tax-Exempt Diversified Portfolio, risk of loss from payment default may also
 exist where municipal instruments backed by foreign letters of credit or guar-
 antees.
 
                                                                               7
<PAGE>
 
 .Liquidity Risk--The risk that a Portfolio will be unable to pay redemption
 proceeds within the time period stated in this Prospectus, because of unusual
 market conditions, an unusually high volume of redemption requests, or other
 reasons.
 .Other Risks--Each Portfolio is subject to other risks, such as the risk that
 its operations, or the value of its portfolio securities, will be disrupted by
 the "Year 2000 Problem."
 
Risk that applies to the Government Portfolio:
 
 .U.S. Government Securities Risk--The risk that the U.S. government will not
 provide financial support to U.S. government agencies, instrumentalities or
 sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Tax-Exempt Diversified Portfolio:
 
 .Concentration Risk--The risk that if the Portfolio invests more than 25% of
 its total assets in issuers within the same state, industry or economic sec-
 tor, an adverse economic, business or political development may affect the
 value of the Portfolio's investments more than if its investments were not so
 concentrated.
 
 .Tax Risk--The risk that future legislative or administrative changes or court
 decisions may materially affect the ability of the Portfolio to pay federal
 tax-exempt dividends.
 
More information about the Portfolio's securities and investment techniques,
and their associated risks, is provided in Appendix A. You should consider the
investment risks discussed in this section and in Appendix A. Both are impor-
tant to your investment choice.

Portfolio Performance
 
 HOW THE PORTFOLIOS PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Portfolio by showing: (a) changes in the performance of a Portfo-
 lio's Oakmark Units from year to year; and (b) the average annual returns of
 a Portfolio's Oakmark Units. Investors should be aware that the fluctuation
 of interest rates is one primary factor in performance volatility. The bar
 chart and table assume reinvestment of dividends and distributions. A Port-
 folio's past performance is not necessarily an indication of how the Portfo-
 lio will perform in the future. Performance reflects expense limitations in
 effect. If expense limitations were not in place a Portfolio's performance
 would have been reduced. You may obtain a Portfolio's current yield by call-
 ing 1-800-OAKMARK (1-800-625-6275).

the current expense limitations, "Other Expenses" and "Total Portfolio

Example
 
 The following Example is intended to help you compare the cost of investing
 in a Portfolio (without the expense limitations) with the cost of investing
 in other mutual funds. The Example assumes that you invest $10,000 in
 Oakmark Units of a Portfolio for the time periods indicated and then redeem
 all of your units at the end of those periods. The Example also assumes that
 your investment has a 5% return each year and that a Portfolio's operating
 expenses remain the same. Although your actual costs may be higher or lower,
 based on these assumptions your costs would be:

 Service Organizations that invest in Oakmark Units on behalf of their cus-
 tomers may charge other fees directly to their customer accounts in connec-
 tion with their investments. You should contact your Service Organization
 for information regarding such charges. Such fees, if any, may affect the
 return such customers realize with respect to their investment.
 
 Certain Service Organizations may receive other compensation in connection
 with the sale and distribution of Oakmark Units or for services to their
 customers' accounts and/or the Portfolios. For additional information
 regarding such compensation, see "Shareholder Guide" in the Prospectus and
 "Other Information" in the Additional Statement.
 
 In addition to Oakmark Units, each Portfolio also offers other classes of
 shares to investors. These other share classes are subject to different fees
 and expenses (which affect performance), have different minimum investment
 requirements and are entitled to different services than Oakmark Units.
 Information regarding these other share classes may be obtained from your
 sales representative or from Oakmark by calling the number on the back cover
 of this Prospectus.

Service Providers
 
 
 INVESTMENT ADVISER
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Portfolios.
 Goldman Sachs registered as an investment adviser in 1981. The Goldman Sachs
 Group, L.P., which controls the Investment Adviser, announced that it will
 pursue an initial public offering of the firm in the late spring or early
 summer of 1999. Simultaneously with the offering, the Goldman Sachs Group,
 L.P. will merge into The Goldman Sachs Group, Inc. As of February 28, 1999,
 GSAM, together with its affiliates, acted as investment adviser or
 distributor for assets in excess of $199 billion.
 
 The Investment Adviser provides day-to-day advice regarding the Portfolios'
 transactions. The Investment Adviser also performs the following services
 for the Portfolios:
 .Continually manages each Portfolio, including the purchase, retention and
  disposition of securities and other assets
 .Administers each Portfolio's business affairs
 .Performs various unitholder servicing functions (to the extent not provided
  by other organizations)
 Pursuant to an SEC order, the Government Portfolio may enter into principal
 transactions in certain taxable money market instruments, including repur-
 chase agreements, with Goldman Sachs.
 
 MANAGEMENT FEES
 
 As compensation for its services and its assumption of certain expenses, the
 Investment Adviser is entitled to the following fees, computed daily and
 payable monthly, at the annual rates listed below:
<TABLE>

                                           Actual Rate For the

                          Contractual Rate December 31, 1998

 -------------------------------------------------------------
  Tax-Exempt Diversified       0.35%              0.29%
 -------------------------------------------------------------
</TABLE>
 
 The difference, if any, between the stated fees and the actual fees paid by
 the Portfolios reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations at any time
 in the future at its discretion.

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Portfolio's units. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606-6372, also serves as the
 Portfolios' transfer agent (the "Transfer Agent") and, as such, performs
 various unitholder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold units of the Portfolios. Goldman Sachs reserves the right to redeem at
 any time some or all of the units acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," leading to computer shutdowns or errors
 (commonly known as the "Year 2000 Problem"). To the extent these systems
 conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Portfolios could be adversely affected in their
 ability to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Portfolio service providers do not adequately
 address this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 .The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
 .The Investment Adviser has sought assurances from the Portfolios' other
  service providers that they are taking the steps necessary so that they do
  not experience Year 2000 Problems, and the Investment Adviser will continue
  to monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Portfolios at current levels.
 
 
                                                                              15
<PAGE>
 
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000
 preparedness of the issuers of securities held by the Portfolios. The
 Investment Adviser may obtain such Year 2000 information from various
 sources which the Investment Adviser believes to be reliable, including the
 issuers' public regulatory filings. However, the Investment Adviser is not
 in a position to verify the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Portfolios' other service providers will be
 sufficient to avoid any adverse effect on the Portfolios due to the Year
 2000 Problem.

Dividends
 
 
 
 All or substantially all of each Portfolio's net investment income will be
 declared as a dividend daily and paid to Harris Associates for distribution
 to holders of Oakmark Units monthly. Dividends will normally, but not
 always, be declared as of 4:00 p.m. New York time. You may choose to have
 dividends paid in:
 .Cash
 .Additional Oakmark Units of the same Portfolio
 
 You may indicate your election on your Account Application. Any changes may
 be submitted in writing to Harris Associates at any time. If you do not
 indicate any choice, your dividends and distributions will be reinvested
 automatically in the applicable Portfolio.
 
 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Portfolio's daily distributions.
 
 Each Portfolio may distribute at least annually other realized capital
 gains, if any, after reduction by available capital losses. In order to
 avoid excessive fluctuations in the amount of monthly capital gains distri-
 butions, a portion of any net capital gains realized on the disposition of
 securities during the months of November and December may be distributed
 during the subsequent calendar year. Although realized gains and losses on
 the assets of a Portfolio are reflected in the NAV of the Portfolio, they
 are not expected to be of an amount which would affect the Portfolio's NAV
 of $1.00 per share.
 
                                                                              17

Unitholder Guide
 
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Portfolios' Oakmark
 Units.
 
 HOW TO BUY OAKMARK UNITS
 
 
 How Can I Purchase Oakmark Units Of The Portfolios?
 You may purchase Oakmark Units of either Portfolio by check, by wire, by
 electronic transfer or by exchange through State Street Bank and Trust Com-
 pany as agent for Harris Associates ("Oakmark"). There are no sales commis-
 sions or underwriting discounts. The minimum initial investment is $1,000 or
 $500 in the case of an Education IRA or participation in the Automatic
 Investment Plan or Payroll Deduction Plan. Minimum subsequent investments
 are $100, except for reinvestments of dividends and capital gain distribu-
 tions.
 
 By Check. To make an initial purchase of units, complete and sign the New
 Account Registration Form and mail it to the Oakmark Family of Funds, P.O.
 Box 8510, Boston, Massachusetts 02266-8510, together with a check for the
 total purchase amount payable to State Street Bank and Trust Company.
 
 You may make subsequent investments by submitting a check (except that a
 third party check will not be accepted) along with either the stub from your
 Portfolio account confirmation statement or a note indicating the amount of
 the purchase, your account number, and the name in which your account is
 registered. Each individual check submitted for purchase must be at least
 $100. Oakmark will not accept cash, drafts, "starter" checks, third party
 checks, or checks drawn on banks outside of the United States. If your order
 to purchase Oakmark Units of a Portfolio is cancelled because your check
 does not clear, you will be responsible for any resulting loss incurred by
 Oakmark.
 
 By Wire Transfer. You may also pay for Oakmark Units by instructing your
 bank to wire money to Oakmark. Your bank may charge you a fee for sending
 the wire. If you are opening a new account by wire transfer, you must first
 telephone Oakmark at 1-800-OAKMARK (1-800-625-6275) to request an account
 number and furnish your social security or other tax identification number.
 Neither the Portfolios nor Oakmark will be responsible for the consequences
 of delays, including delays in the banking or Federal Reserve wire systems.

                                                                UNITHOLDER GUIDE
 
 By Electronic Transfer. If you have an established Portfolio account you may
 make subsequent investments by an electronic transfer of funds from your
 bank account. Electronic transfer allows you to make purchases at your
 request by calling 1-800-OAKMARK (1-800-625-6275) or at pre-scheduled inter-
 vals. (See "Unitholder Services.") You may not open a new account through
 electronic transfer.
 
 By Exchange. You may purchase Oakmark Units of the Portfolios by exchange of
 Oakmark Units from the Goldman Sachs Short Duration Tax-Free Fund or shares
 from The Oakmark Fund, The Oakmark Select Fund, The Oakmark International
 Fund, The Oakmark Small Cap Fund, The Oakmark Equity and Income Fund and The
 Oakmark International Small Cap Fund ("The Oakmark Funds") either by phone
 or by mail. An exchange transaction is a sale and purchase for federal
 income tax purposes and may result in capital gain or loss. Please review
 the information under "How to Redeem Units--By Exchange."
 
 Purchase Amount and Dividends. Oakmark Units of each Portfolio may be pur-
 chased on any business day at the net asset value ("NAV") next determined
 after receipt by Oakmark of both the purchase order and the purchase amount
 in federal funds.
 Purchases of Oakmark Units may be made by check or wire transfer. Purchases
 are effective as soon as a check is converted to Federal Funds. Purchases by
 wire transfer will be effected the day the wire transfer is received if the
 wire transfer is received prior to the respective Portfolio's cut-off time
 as noted below. It is expected that checks will ordinarily be converted to
 federal funds within two business days after receipt. A purchase by check is
 deemed to be effective prior to the Portfolio's cut-off time noted below on
 the date such purchase proceeds convert to Federal Funds. Oakmark Units pur-
 chased by check may not be redeemed until the check has cleared, as
 described under "How to Redeem Units."
 Oakmark Units of the Government Portfolio are deemed to have been purchased
 when an order becomes effective and are entitled to dividends as follows:

 General. Each purchase order for Oakmark Units must be accepted by Oakmark.
 Once your purchase order has been accepted, you may not cancel or revoke it;
 however, you may redeem the Oakmark Units. Oakmark reserves the right not to
 accept any purchase order that it determines not to be in the best interest
 of the Trust or of a Portfolio's unitholders. Oakmark uses procedures
 designed to give reasonable assurance that telephone instructions are genu-
 ine, including recording telephone calls, testing a caller's identity and
 sending written confirmation of telephone transactions. If Oakmark does not
 follow such procedures, it may be liable for losses due to unauthorized or
 fraudulent telephone instructions. Oakmark will not be liable for acting
 upon instructions communicated by telephone that it reasonably believes to
 be genuine.
 
 What Do I Need To Know About Service Organizations?
 Service Organizations, including Harris Associates, may provide the follow-
 ing services in connection with their customers' investments in ILA Service
 Units:
 .Acting, directly or through an agent, as the sole unitholder of record
 .Maintaining account records for customers
 .Processing orders to purchase, redeem or exchange units for customers
 .Responding to inquiries from prospective and existing unitholders
 .Assisting customers with investment procedures
 
 Pursuant to a service plan adopted by the Trust's Board of Trustees, Service
 Organizations are entitled to receive payment for their services from the
 Trust of up to 0.40% (on an annualized basis) of the average daily net
 assets of the ILA Service Units of the Portfolios, which are attributable to
 or held in the name of the Service Organization for its customers. In addi-
 tion, GSAM, at its own expense, may pay a Service Organization up to 0.10%
 of the average daily net assets of the ILA Service Units of the Portfolio,
 which are attributable to or held in the name of the Service Organization
 for its customers. Such compensation does not represent an additional
 expense to a Portfolio or its unitholders, since it will be paid from the
 assets of GSAM.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Portfolios, to selected Service Organizations and
 other persons in connection with the sale, distribution and/or servicing of
 units of the Portfolios and other Goldman Sachs Funds. Subject to applicable
 NASD regulations, the Investment Adviser, Distributor and/or their affili-
 ates may also contribute to various cash and non-cash incentive arrangements
 to promote the sale of units. This additional compensation can vary among
 Service Organizations depending upon such factors as the amounts their cus-
 tomers have invested (or may invest) in particular Goldman Sachs Funds, the
 particular program involved, or the amount of reimbursable expenses.

 How Are Units Priced?
 The price you pay or receive when you buy, sell or exchange Oakmark Units is
 determined by a Portfolio's NAV. The Portfolios calculate NAV as follows:
 
                (Value of Assets of the Class)
                 - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Units of the Class
 
 .NAV per unit each class is calculated by State Street Bank and Trust Com-
  pany (each Portfolio's Custodian) on each business day as of the close of
  regular trading on the New York Stock Exchange (normally 4:00 p.m. New York
  time). Portfolio units will be priced on any day the New York Stock
  Exchange is open, except for days on which Chicago, Boston or New York
  banks are closed for local holidays.
 .On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Portfolio reserves the right
  to close at or prior to the BMA recommended closing time. If a Portfolio
  does so, it will cease granting same business day credit for purchase and
  redemption orders received after the Portfolio's closing time and credit
  will be given to the next business day.
 .The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Portfolio maintain its $1.00 constant unit price, portfolio
 securities are valued at amortized cost in accordance with SEC regulations.
 Amortized cost will normally approximate market value. There can be no
 assurance that a Fund will be able at all times to maintain a NAV of $1.00
 per unit.
 
 HOW TO SELL OAKMARK UNITS
 
 
 How Can I Sell Oakmark Units Of The Portfolios?
 
 By Mail. You may redeem all or any part of your Oakmark Units of a Portfolio
 upon your written request delivered to the Oakmark Family of Funds, P.O. Box
 8510, Boston, Massachusetts 02266-8510.
 
 Your redemption request must:
 .identify the Portfolio and give your account number;
 .specify the number of units or dollar amount to be redeemed;
 .be signed in ink by all owners exactly as their names appear on the
  account; and
 
                                                                              21
<PAGE>
 
 
 .for redemptions payable to an address other than the unitholder address of
  record, include an ink-stamped guarantee by an "eligible guarantor
  institution" as defined in the Securities Exchange Act of 1934 (including a
  bank, broker, dealer, credit union, national securities exchange,
  registered securities association, clearing agency or savings association,
  but not a notary public) for each signature on the redemption request (the
  guarantee must use the phrase "signature guaranteed" and must include the
  name of the guarantor bank firm and an authorized signature).
 
 Special rules apply to redemptions by corporations, trusts and partnerships.
 In the case of a corporation, the request must be signed in the name of the
 corporation by an officer whose title must be stated, and must be accompa-
 nied by a bylaw provision or resolution of the board of directors, certified
 within 60 days, authorizing the officer to so act. A redemption request from
 a partnership or a trust must be signed in the name of the partnership or
 trust by a general partner or a trustee and include a signature guarantee.
 If the trustee is not named in the account registration, a redemption
 request by a trust must also include evidence of the trustee's appointment
 as such (e.g., a certified copy of the relevant portions of the trust
 instrument). Under certain circumstances, before Oakmark Units can be
 redeemed, additional documents may be required in order to verify the
 authority of the person seeking to redeem.
 
 By Exchange. You may redeem all or any portion of your Oakmark Units of a
 Portfolio and use the proceeds to purchase Oakmark Units of the Goldman
 Sachs Short Duration Tax-Free Fund (until May 31, 1999 and thereafter ILA
 Service Units) or shares of The Oakmark Funds if your signed, properly com-
 pleted New Account Registration Form is on file. An exchange transaction is
 a sale and purchase for federal income tax purposes and may result in capi-
 tal gain or loss. Before exchanging, you should obtain a prospectus from The
 Oakmark Family of Funds and read it carefully. The exchange privilege is not
 an offering or recommendation of shares of The Oakmark Funds or the Goldman
 Sachs Short Duration Tax-Free Fund. The registration of the account to which
 you are making an exchange must be exactly the same as that of the account
 from which the exchange is made and the amount you exchange must meet any
 applicable minimum investment of the fund being purchased. An exchange may
 be made by following the redemption procedure described above under "By
 Mail" and indicating the fund to be purchased, except that a signature guar-
 antee normally is not required. (See also the discussion below of the Tele-
 phone Exchange Privilege.)
 
 Special Redemption Privileges. The Telephone Exchange and Telephone Redemp-
 tion Privileges will be established automatically when you open your
 account.
 Other Privileges must be specifically elected. A signature guarantee may be

                                                                UNITHOLDER GUIDE
 
 required to establish a Privilege after you open your account. Oakmark Units
 held in an IRA account may not be redeemed by telephone.
 
 By Check. Holders of Oakmark Units of a Portfolio may elect to have checks
 issued to them in order to redeem Oakmark Units from their accounts in each
 Portfolio. When Oakmark receives a completed New Account Registration Form
 and signature card, Oakmark will forward to the requesting customer a supply
 of checks. Checks drawn on this account may be payable to the order of any
 person in any amount of $500 or more, but cannot be certified. The payee of
 the check may cash or deposit it like any other check drawn on a bank. When
 such a check is presented to Oakmark for payment, a sufficient number of
 full and fractional Oakmark Units will be redeemed to cover the amount of
 the check. Cancelled checks will be returned to the recordholder of Oakmark
 Units by Oakmark.
 
 The check redemption privilege enables a unitholder to receive the dividends
 declared on the Oakmark Units to be redeemed until the date the check is
 processed. Because of this feature, the check redemption privilege may not
 be used for complete liquidation of a unitholder's account. If the amount of
 a check is greater than the value of the Oakmark Units held in the
 unitholder's account, the check will be returned unpaid, and the unitholder
 may be subject to extra charges.
 
 Oakmark reserves the right to impose conditions on, limit the availability
 of or terminate the check redemption privilege at any time with respect to a
 particular unitholder or all unitholders in general. The Portfolios and
 Oakmark reserve the right at any time to suspend the procedure permitting
 redemptions by check and intend to do so in the event that federal legisla-
 tion or regulations impose reserve requirements or other restrictions deemed
 by the Trustees to be adverse to the interests of other Oakmark unitholders
 of the Portfolios.
 
 Telephone Exchange Privilege. You may use the Telephone Exchange Privilege
 to exchange among The Oakmark Funds and the Portfolios by calling 1-800-
 OAKMARK (1-800-625-6275). The general redemption policies apply to redemp-
 tions by Telephone Exchange. (See "General Redemption Policies.")
 
 Oakmark reserves the right at any time without prior notice to suspend or
 terminate the use of the Telephone Exchange Privilege by any person or class
 of persons. Oakmark believes that use of the Telephone Exchange Privilege by
 investors utilizing market-timing strategies adversely affects the Portfo-
 lios. Therefore, Oakmark generally will not honor requests for Telephone
 Exchanges by unitholders identified by Oakmark as "market-timers." Except
 for automatic exchanges from Oakmark Units, you may not make more than four
 exchanges from any Portfolio in any calendar year. Oakmark reserves the
 right at any time without prior notice to suspend, limit, modify, or termi-
 nate the Telephone
 
                                                                              23
<PAGE>
 
 
 Exchange Privilege in its entirety. Because such a step would be taken only
 if it would be in the best interests of the Portfolios, Oakmark expects that
 it would provide unitholders with prior written notice of any such action
 unless it appears that the resulting delay in the suspension, limitation,
 modification, or termination of the Telephone Exchange Privilege would
 adversely affect the Portfolios. If Oakmark were to suspend, limit, modify,
 or terminate the Telephone Exchange Privilege, you might find that an
 exchange could not be processed or that there might be a delay in the imple-
 mentation of the exchange. See "How to Redeem Units--By Exchange."
 
 During periods of volatile economic and market conditions, you may have dif-
 ficulty placing your exchange by telephone; you may wish to consider placing
 your exchange by mail during such periods.
 
 Telephone Redemption Privilege. You may use the Telephone Redemption Privi-
 lege to redeem Oakmark Units by calling 1-800-OAKMARK (1-800-625-6275). The
 proceeds may be sent by check to your registered address or you may request
 payment by electronic transfer to a bank account previously designated by
 you at a bank that is a member of the Automated Clearing House. If you
 request a redemption by electronic transfer before the applicable Portfo-
 lio's redemption cut-off time and the proceeds are to be sent to your pre-
 established designated bank account, the proceeds will be transferred to
 your bank account on that business day. The Telephone Redemption Privilege
 is not available to redeem units held in an IRA account, and is not avail-
 able for 30 days after Oakmark receives notice from you of a change of
 address.
 
 General Redemption Policies. You may not cancel or revoke your redemption
 order once instructions have been received and accepted. Please telephone
 Oakmark by calling 1-800-OAKMARK (1-800-625-6275) if you have any questions
 about requirements for a redemption before submitting your request. Oakmark
 reserves the right to require a properly completed New Account Registration
 Form before making payment for Oakmark Units redeemed.
 
 If your redemption order is received in proper form before 4:00 p.m. eastern
 time, the price at your redemption order will be executed is the net asset
 value determined that business day. See "Net Asset Value." Dividends are
 earned on the day that units are redeemed.
 
 Oakmark will generally mail payment for Oakmark Units redeemed within three
 days after proper instructions are received. If you attempt to redeem
 Oakmark Units within 15 days after they have been purchased by check or
 electronic transfer, Oakmark may delay payment of the redemption proceeds to
 you until it can verify that payment for the purchase of those Oakmark Units
 has been (or will be)

 collected. To reduce such delays, Oakmark recommends that your purchase be
 made by Federal Funds wire through your bank. If you so request, the pro-
 ceeds of your redemption may be paid by wire, provided the redemption pro-
 ceeds are at least $250, but the cost of the wire (currently $5) will be
 deducted from the redemption proceeds.
 
 Oakmark reserves the right at any time without prior notice to suspend, lim-
 it, modify, or terminate any privilege or its use in any manner by any per-
 son or class.
 
 Use of any Special Redemption Privilege authorizes Oakmark to tape-record
 all instructions to redeem. Oakmark uses procedures designed to give reason-
 able assurance that telephone instructions are genuine, including recording
 telephone calls, testing a caller's identity and sending written confirma-
 tion of telephone transactions. If Oakmark does not follow such procedures,
 it may be liable for losses due to unauthorized or fraudulent telephone
 instructions. The Trust, the Distributor and Oakmark will not be liable for
 any loss you may incur in the event that Oakmark accepts unauthorized tele-
 phone redemption requests that Oakmark reasonably believes to be genuine.
 
 Oakmark reserves the right to redeem Oakmark Units in any account and send
 the proceeds to the owner if the Oakmark Units in the account do not have a
 value of at least $1,000.
 
 Oakmark Units in any account you maintain with the Portfolios may be
 redeemed to the extent necessary to reimburse Oakmark for any loss it sus-
 tains that is caused by you (such as losses from uncollected checks and
 electronic transfers or any liability under the Code provisions on backup
 withholding relating to your account).
 
 Effective May 31, 1999, the exchange privilege with the Service Units (also
 known as "Oakmark Units") of the Tax-Exempt Diversified Portfolio and the
 Goldman Sachs Short Duration Tax Free Fund, mentioned on page 19, will be
 discontinued. In addition, you will not be able to initiate any new pur-
 chases of the Tax-Exempt Diversified Portfolio or the Short Duration Tax
 Free Fund after that date.
 
 The exchange privilege will still be available with respect to Oakmark Units
 of the Government Portfolio. After May 31, 1999, you will be asked to con-
 vert any Oakmark Units you have in the Tax-Exempt Diversified Portfolio or
 the Short Duration Tax Free Fund to Oakmark Units of the Government Portfo-
 lio if you want to continue having exchange privileges with the Oakmark
 Funds.
 
                                                                              25

 Payment of Redemption Proceeds and Dividends. Oakmark Units of each Portfo-
 lio may be redeemed without charge upon request on any business day at the
 net asset value next determined after receipt by Oakmark of the redemption
 request.
 
 What Types Of Reports Will I Be Sent Regarding Investments In Oakmark Units?
 You will receive a confirmation statement from Oakmark reflecting each of
 your purchases and redemptions of Oakmark Units, as well as periodic state-
 ments detailing distributions made by the Portfolios. In addition, Oakmark
 will send you semiannual and annual reports containing audited financial
 statements and will provide you annually with tax information.
 
 UNITHOLDER SERVICES
 
 IRA Plan. Harris Associates Investment Trust has a master individual retire-
 ment account (IRA) plan that allows you to invest on a tax-deferred basis in
 the Government Portfolio and The Oakmark Funds as defined below. The plan
 also permits you to "roll over" or transfer to your Oakmark IRA a lump sum
 distribution from a qualified pension or profit-sharing plan, thereby post-
 poning federal income tax on the distribution. If your employer has a Sim-
 plified Employee Pension Plan (SEP), you may establish an IRA with the Gov-
 ernment Portfolio and the Funds to which your employer may contribute
 annually up to the lesser of 15% of your earned income or $30,000, subject
 to special rules designed to avoid discrimination. Because the Trust has
 determined that the Tax-Exempt Diversified Portfolio is not a suitable
 investment for IRA accounts, that Portfolio is not available for IRA invest-
 ments.
 
 SPECIAL WAYS TO INVEST OR REDEEM
 
 In addition to the ways to purchase or redeem Oakmark Units described above,
 the New Account Registration Form offers you the following additional
 investment and redemption options:
 
 Automatic Investments--purchase Oakmark Units each month with payment by
 electronic transfer from your bank account ($100-$50,000 per transaction).

                                                                UNITHOLDER GUIDE
 
 
 Telephone Investments--purchase Oakmark Units by placing a telephone order
 and paying for them by electronic transfer from your bank account ($100-
 $50,000 per transaction).
 
 Systematic Withdrawals--redeem a fixed dollar amount of Oakmark Units each
 month or quarter and have the proceeds sent by check to you or deposited by
 electronic transfer into your bank account (up to $50,000 per transaction
 for electronic transfers).
 
                                                                              27

Taxation
 
Each Portfolio intends to qualify as a regulated investment company for federal
tax purposes, and to distribute to unitholders substantially all of its net
investment income.
 
Except for the Tax-Exempt Diversified Portfolio, Portfolio dividends will gen-
erally be taxable to you as ordinary income (unless your investment is in an
IRA or other tax-advantaged account) regardless of whether you reinvest in
additional Oakmark Units or take them as cash. The Tax-Exempt Diversified Port-
folio expects generally to distribute "exempt-interest dividends," which will
be tax-exempt income for federal income tax purposes. The tax status and
amounts of the dividends for each calendar year will be detailed in your annual
tax statement from Harris Associates.
 
Dividends and distributions from each Portfolio will generally be taxable to
you in the tax year in which they are paid, with one exception. Dividends and
distributions declared by a Portfolio in October, November or December and paid
in January are taxed as though they were paid by December 31.
 
Interest on indebtedness incurred by you to purchase or carry units of the Tax-
Exempt Diversified Portfolio generally will not be deductible for income tax
purposes.
 
You should note that a portion of the exempt-interest dividends paid by the
Tax-Exempt Diversified Portfolio may be an item of tax preference for purposes
of determining your AMT liability. Exempt-interest dividends will also be con-
sidered along with other adjusted gross income in determining whether any
Social Security or railroad retirement payments received by you are subject to
federal income taxes.
 
In addition to federal income taxes, you may be subject to state, local or for-
eign taxes on payments received from either Portfolio or on the value of the
units held by you. More tax information is provided in the Additional State-
ment. You should also consult your own tax adviser for information regarding
all tax consequences applicable to your investments in the Portfolios.

Appendix A
Additional Information on Portfolio
Risks, Securities and Techniques
 
This section provides further information on certain types of securities and
investment techniques that may be used by the Portfolios, including their asso-
ciated risks. Additional information is provided in the Additional Statement,
which is available upon request. Among other things, the Additional Statement
describes certain fundamental policies and investment restrictions that cannot
be changed without unitholder approval. You should note, however, that all pol-
icies not specifically designated as fundamental are non-fundamental and may be
changed without unitholder approval. If there is a change in a Portfolio's
investment objective, you should consider whether that Portfolio remains an
appropriate investment in light of your then current financial position and
needs.
 
U.S. Treasury Obligations and U.S. Government Securities and Related Custodial
Receipts. U.S. Treasury Obligations include securities issued or guaranteed by
the U.S. Treasury ("U.S. Treasury Obligations"). Payment of principal and
interest on these obligations is backed by the full faith and credit of the
U.S. government. U.S. Treasury Obligations include, among other things, the
separately traded principal and interest components of securities guaranteed or
issued by the U.S. Treasury if such components are traded independently under
the Separate Trading of Registered Interest and Principal of Securities program
("STRIPS"). Both Portfolios may invest in STRIPS.
 
U.S. Government Securities are obligations issued or guaranteed by U.S. govern-
ment agencies, authorities, instrumentalities or sponsored enterprises ("U.S.
Government Securities"). Unlike U.S. Treasury Obligations, U.S. Government
Securities can be supported by either (a) the full faith and credit of the U.S.
Treasury (such as the Government National Mortgage Association ("Ginnie Mae"));
(b) the right of the issuer to borrow from the U.S. Treasury (such as securi-
ties of the Student Loan Marketing Association); (c) the discretionary author-
ity of the U.S. government to purchase certain obligations of the issuer (such
as the Federal National Mortgage Association ("Fannie Mae") and Federal Home
Loan Mortgage Corporation ("Freddie Mac")); or (d) only the credit of the issu-
er.
 
U.S. Government Securities are deemed to include (a) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, its agencies, authorities or instrumentalities;
and (b) participations in loans made to foreign governments or their agencies
that are so guaranteed. Certain of these participations may be regarded as
illiquid. U.S. Government Securities also include zero coupon bonds.
 
                                                                              29
<PAGE>
 
 
 
U.S. Government Securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
government will provide financial support to U.S. government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
The Tax-Exempt Diversified Portfolio may also acquire U.S. Government Securi-
ties in the form of custodial receipts. Custodial receipts evidence ownership
of future interest payments, principal payments or both on notes or bonds
issued or guaranteed as to principal or interest by the U.S. government, its
agencies, instrumentalities, political subdivisions or authorities. For certain
securities law purposes, custodial receipts are not considered obligations of
the U.S. government.
 
Commercial Paper. The Tax-Exempt Diversified Portfolio may invest in commercial
paper, including variable amount master demand notes and asset-backed commer-
cial paper. Commercial paper represents short-term unsecured promissory notes
issued in bearer form by banks or bank holding companies, corporations, finance
companies and other issuers. The commercial paper purchased by the Fund con-
sists of direct U.S. dollar-denominated obligations of domestic issuers.
 
Repurchase Agreements. The Government Portfolio may enter into repurchase
agreements with primary dealers in U.S. Government Securities and banks
affiliated with primary dealers. Repurchase agreements involve the purchase of
securities subject to the seller's agreement to repurchase them at a mutually
agreed upon date and price.
 
If the other party or "seller" defaults, a Portfolio might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Portfolio are less than the repurchase price and the
Portfolio's cost associated with delay and enforcement of the repurchase agree-
ment. In addition, in the event of bankruptcy of the seller, a Portfolio could
suffer additional losses if a court determines that the Portfolio's interest in
the collateral is not enforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Portfolio's
unitholders. In addition, each Portfolio, together with other registered
investment companies having advisory agreements with the Investment Adviser or
any of its affiliates, may transfer uninvested cash balances into a single
joint account, the daily aggregate balance of which will be invested in one or
more repurchase agreements.
 
Municipal Obligations. Certain Funds may invest in municipal obligations.
Municipal obligations are issued by or on behalf of states, territories and
possessions

                                                                      APPENDIX A
 
of the United States and their political subdivisions, agencies, authorities
and instrumentalities, and the District of Columbia. Municipal obligations may
include fixed rate notes and similar debt instruments; variable and floating
rate demand instruments; tax-exempt commercial paper; municipal bonds; and
unrated notes, paper, bonds or other instruments.
 
Municipal Notes and Bonds. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
Tender Option Bonds. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate and
the rate, as determined by a remarketing or similar agent, that would cause the
securities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term,
tax-exempt rate. An institution will normally not be obligated to accept ten-
dered bonds in the event of certain defaults or a significant downgrading in
the credit rating assigned to the issuer of the bond. The tender option will be
taken into account in determining the maturity of the tender option bonds and a
Portfolio's average portfolio maturity. There is a risk that a Portfolio will
not be considered the owner of a tender option bond for federal income tax pur-
poses, and thus will not be entitled to treat such interest as exempt from fed-
eral income tax. Certain tender option bonds may be illiquid or may become
illiquid as a result of a credit rating downgrade, a payment default or a dis-
qualification from tax-exempt status.

Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which include a demand feature that permits the
holder to sell the RAWs to a bank or other financial institution at a purchase
price equal to par plus accrued interest on each interest rate reset date.
 
Industrial Development Bonds. Industrial development bonds (private activity
bonds) are a specific type of revenue bond backed by the credit and security of
a private user, the interest from which would be an item of tax preference when
distributed by a Fund as "exempt-interest dividends" to unitholders under AMT.
 
Other Municipal Obligation Policies. Ordinarily, the Tax-Exempt Diversified
Portfolio expects that 100% of its portfolio securities will be municipal obli-
gations. However, the Portfolio may invest 25% or more of the value of its
total assets in municipal obligations which are related in such a way that an
economic, business or political development or change affecting one municipal
obligation would also affect the other municipal obligation. For example, the
Tax-Exempt Diversified Portfolio may invest all of its assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities; (b) municipal obligations whose issuers are in the same
state; or (c) industrial development obligations. Concentration of the Portfo-
lio's investments in these municipal obligations will subject the Portfolio, to
a greater extent than if such investment was not so concentrated, to the risks
of adverse economic, business or political developments affecting the particu-
lar state, industry or other area of concentration.
 
The Tax-Exempt Diversified Portfolio may purchase municipal obligations which
are backed by letters of credit or other forms of credit enhancement issued by
domestic banks or foreign banks which have a branch, agency or subsidiary in
the United States or by other financial institutions. The credit quality of
these banks and financial institutions could, therefore, cause a loss to the
Tax-Exempt Diversified Portfolio. Letters of credit and other obligations of
foreign banks and financial institutions may involve risks in addition to those
of domestic obligations because of less publicly available financial and other
information, less securities regulation, potential imposition of foreign with-
holding and other taxes, war, expropriation or other adverse governmental
actions. Foreign banks and their foreign branches are not regulated by U.S.
banking authorities, and are generally not bound by the accounting, auditing
and financial reporting standards applicable to U.S. banks. In addition, the
Portfolio may acquire securities in the form of custodial receipts which evi-
dence

                                                                      APPENDIX A
 
ownership of future interest payments, principal payments or both on obliga-
tions of certain state and local governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, the Tax-Exempt Diversified Portfolio may acquire the right to sell the
obligation to another party at a guaranteed price and date.
 
Floating and Variable Rate Obligations. The Portfolios may purchase floating
and variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Act, a Portfolio may consider the maturity of a variable or floating rate
obligation to be shorter than its ultimate stated maturity if the obligation is
a U.S. Treasury Obligation or U.S. Government Security, if the obligation has a
remaining maturity of 397 calendar days or less, or if the obligation has a
demand feature that permits the Portfolio to receive payment at any time or at
specified intervals not exceeding 397 calendar days. The issuers or financial
intermediaries providing demand features may support their ability to purchase
the obligations by obtaining credit with liquidity supports. These may include
lines of credit, which are conditional commitments to lend and letters of cred-
it, which will ordinarily be irrevocable, both of which may be issued by domes-
tic banks or foreign banks which have a branch, agency or subsidiary in the
United States. A Portfolio may purchase variable or floating rate obligations
from the issuers or may purchase certificates of participation, a type of
floating or variable rate obligation, which are interests in a pool of debt
obligations held by a bank or other financial institution.
 
When-Issued Securities and Forward Commitments. Each Portfolio may purchase
when-issued securities and make contracts to purchase or sell securities for a
fixed price at a future date beyond customary settlement time. When-issued
securities are securities that have been authorized, but not yet issued. When-
issued securities are purchased in order to secure what is considered to be an
advantageous price and yield to a Portfolio at the time of entering into the
transaction. A forward commitment involves entering into a contract to purchase
or sell securities for a fixed price at a future date beyond the customary set-
tlement period.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the risk that the value of the securities sold may
increase before the settlement date. Although a Portfolio will generally pur-
chase securities on a when-issued or forward commitment basis with the inten-
tion of acquiring securities for its portfolio, a Portfolio may dispose of
when-issued securities or forward commitments prior to settlement if the
Investment Adviser deems it appropriate.
 
                                                                              33

Other Investment Companies. A Portfolio may invest in securities of other
investment companies subject to the limitations prescribed by the Act. These
limitations include a prohibition on any Portfolio acquiring more than 3% of
the voting units of any other investment company, and a prohibition on invest-
ing more than 5% of a Portfolio's total assets in securities of any one invest-
ment company or more than 10% of its total assets in securities of all invest-
ment companies. A Portfolio will indirectly bear its proportionate share of any
management fees and other expenses paid by such other investment companies.
Such other investment companies will have investment objectives, policies and
restrictions substantially similar to those of the acquiring Portfolio and will
be subject to substantially the same risks.
 
Illiquid Securities. Each Portfolio may invest up to 10% of its net assets in
illiquid securities which cannot be disposed of in seven days in the ordinary
course of business at fair value. Illiquid securities include:
 .Both domestic and foreign securities that are not readily marketable
 .Certain municipal leases and participation interests
 .Certain stripped mortgage-backed securities
 .Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
 .Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that such restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Portfolio's
portfolio.
 
Borrowings. Each Portfolio may borrow up to 33 1/3% of its total assets from
banks for temporary or emergency purposes. A Portfolio may not make additional
investments if borrowings exceed 5% of its net assets. For more information,
see the Additional Statement.
 
Downgraded Securities. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Portfolio may continue
to hold the security if the Investment Adviser believes it is in the best
interest of the Portfolio and its unitholders.
 
Fundamental Policies. As a matter of fundamental policy, at least 80% of the
net assets of the Tax-Exempt Diversified Portfolio will ordinarily be invested
in municipal obligations, the interest from which is, in the opinion of bond
counsel, if any, excluded from gross income for federal income tax purposes.
 
The Tax-Exempt Diversified Portfolio may temporarily invest in taxable money
market instruments when the Investment Adviser believes that the market condi-
tions dictate a defensive posture. Investments in taxable money market instru-
ments will be limited to those meeting the quality standards of the Tax-Exempt
Diversified Portfolio.

Appendix B
Financial Highlights
 The financial highlights tables are intended to help you understand a Port-
 folio's financial performance for the past five years (or less if the Port-
 folio has been in operation for less than five years). Certain information
 reflects financial results for a single Portfolio unit. The total returns in
 the table represent the rate that an investor would have earned or lost on
 an investment in a Portfolio (assuming reinvestment of all dividends and
 distributions). This information has been audited by Arthur Andersen LLP,
 whose report, along with a Portfolio's financial statements, is included in
 the Portfolio's annual report (available upon request from Harris Associates
 without charge).

                 INVESTMENT POLICIES AND PRACTICES OF THE SERIES

      Each Series is a separate pool of assets which pursues its investment
objective through separate investment policies. Each Series other than ILA
Tax-Exempt California Portfolio and ILA Tax-Exempt New York Portfolio is a
diversified, open-end management investment company. The ILA Tax-Exempt
California Portfolio and ILA Tax-Exempt New York Portfolio are non-diversified
open-end management companies. The following discussion elaborates on the
description of each Series' investment policies and practices contained in the
Prospectus:

U.S. Government Securities

      Securities guaranteed as to principal and interest by the U.S. Government,
it agencies, authorities or instrumentalities are deemed to include (a)
securities for which the payment of principal and interest is backed by an
irrevocable letter of credit issued by the U.S. Government, its agencies,
authorities or instrumentalities and (b) participations in loans made to foreign
governments or their agencies that are so guaranteed. The secondary market for
certain of these participations is limited. Such participations may therefore be
regarded as illiquid.

      Each Series may invest in separately traded principal and interest
components of securities issued or guaranteed by the U.S. Treasury. The
principal and interest components of selected securities are traded
independently under the Separate Trading of Registered Interest and Principal of
Securities program ("STRIPS"). Under the STRIPS program, the principal and
interest components are individually numbered and separately issued by the U.S.
Treasury at the request of depository financial institutions, which then trade
the component parts independently.

Custodial Receipts

      Each Series (other than ILA Treasury Obligations Portfolio, ILA Treasury
Instruments Portfolio, ILA Federal Portfolio, ILA Government Portfolio, FS
Treasury Obligations Fund, FS Government Fund, FS Treasury Instruments Fund and
FS Federal Fund) may also acquire securities issued or guaranteed as to
principal and interest by the U.S. Government, its agencies, authorities or
instrumentalities in the form of custodial receipts that evidence ownership of
future interest payments, principal payments or both on certain U.S. Government
notes or bonds. Such notes and bonds are held in custody by a bank on behalf of
the owners. These custodial receipts are known by various names, including
"Treasury Receipts," "Treasury Investors Growth Receipts" ("TIGRs"), and
"Certificates of Accrual on Treasury Securities" ("CATS"). Although custodial
receipts are not considered U.S. Government Securities for certain securities
law purposes, they are indirectly issued or guaranteed as to principal and
interest by the U.S. Government, its agencies, authorities or instrumentalities.

Bank and Corporate Obligations

      Each Series (other than ILA Treasury Obligations Portfolio, ILA Government
Portfolio, ILA Federal Portfolio, ILA Treasury Instruments Portfolio, FS
Treasury Obligations Fund, FS 


                                      -1-
<PAGE>
 
Government Fund, FS Treasury Instruments Fund and FS Federal Fund) may invest in
commercial paper, including variable amount master demand notes and asset-backed
commercial paper. Commercial paper represents short-term unsecured promissory
notes issued in bearer form by banks or bank holding companies, corporations,
and finance companies. The commercial paper purchased by the Series consists of
direct U.S. dollar denominated obligations of domestic or, in the case of ILA
Money Market Portfolio, FS Money Market Fund and FS Premium Fund, foreign
issuers. Bank obligations in which the Series may invest include certificates of
deposit, bankers' acceptances, fixed time deposits and bank notes. Certificates
of deposit are negotiable certificates issued against funds deposited in a
commercial bank for a definite period of time and earning a specified return.

      Bankers' acceptances are negotiable drafts or bills of exchange, normally
drawn by an importer or exporter to pay for specific merchandise, which are
"accepted" by a bank, meaning, in effect, that the bank unconditionally agrees
to pay the face value of the instrument on maturity. Fixed time deposits are
bank obligations payable at a stated maturity date and bearing interest at a
fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but
may be subject to early withdrawal penalties which vary depending upon market
conditions and the remaining maturity of the obligation. There are no
contractual restrictions on the right to transfer a beneficial interest in a
fixed time deposit to a third party, although there is no market for such
deposits. Bank notes and bankers' acceptances rank junior to domestic deposit
liabilities of the bank and pari passu with other senior, unsecured obligations
of the bank. Bank notes are not insured by the Federal Deposit Insurance
Corporation or any other insurer. Deposit notes are insured by the Federal
Deposit Insurance Corporation only to the extent of $100,000 per depositor per
bank.

      The ILA Money Market Portfolio, FS Money Market Fund and FS Premium Money
Market Fund will invest more than 25% of their total assets in bank obligations
(whether foreign or domestic), including bank commercial paper. However, if
adverse economic conditions prevail in the banking industry (such as substantial
losses on loans, increases in non-performing assets and charge-offs and declines
in total deposits) these Funds may, for defensive purposes, temporarily invest
less than 25% of their total assets in bank obligations. As a result, the Funds
may be especially affected by favorable and adverse developments in or related
to the banking industry. The activities of U.S. banks and most foreign banks are
subject to comprehensive regulations which, in the case of U.S. regulations,
have undergone substantial changes in the past decade. The enactment of new
legislation or regulations, as well as changes in interpretation and enforcement
of current laws, may affect the manner of operations and profitability of
domestic and foreign banks. Significant developments in the U.S. banking
industry have included increased competition from other types of financial
institutions, increased acquisition activity and geographic expansion. Banks may
be particularly susceptible to certain economic factors, such as interest rate
changes and adverse developments in the market for real estate. Fiscal and
monetary policy and general economic cycles can affect the availability and cost
of funds, loan demand and asset quality and thereby impact the earnings and
financial conditions of banks.

      The ILA Prime Obligations Portfolio, ILA Money Market Portfolio, FS Prime
Obligations Fund, FS Premium Fund and FS Money Market Fund may invest in other
short-term 


                                      -2-
<PAGE>
 
obligations, including short-term funding agreements payable in U.S. dollars and
issued or guaranteed by U.S. corporations, foreign corporations (with respect to
the ILA Money Market Portfolio, FS Money Market Fund and FS Premium Fund) or
other entities. A funding agreement is a contract between an issuer and a
purchaser that obligates the issuer to pay a guaranteed rate of interest on a
principal sum deposited by the purchaser. Funding agreements will also guarantee
the return of principal and may guarantee a stream of payments over time. A
funding agreement has a fixed maturity date and may have either a fixed or
variable interest rate that is based on an index and guaranteed for a set time
period. Because there is no secondary market for these investments, any such
funding agreement purchased by a Series will be regarded as illiquid.

Repurchase Agreements

      Each Series (other than the ILA Treasury Instruments Portfolio and FS
Treasury Instruments Fund) may enter into repurchase agreements with primary
dealers in U.S. Government Securities and banks affiliated with such primary
dealers. A repurchase agreement is an arrangement under which the purchaser
(i.e., the Series) purchases a U.S. Government security or other high quality
short-term debt obligation (the "Obligation") and the seller agrees, at the time
of sale, to repurchase the Obligation at a specified time and price.

      Custody of the Obligation will be maintained by the Series' custodian or
subcustodian for the duration of the agreement. The repurchase price may be
higher than the purchase price, the difference being income to the Series, or
the purchase and repurchase prices may be the same, with interest at a stated
rate due to the Series together with the repurchase price on repurchase. In
either case, the income to the Series is unrelated to the interest rate on the
Obligation subject to the repurchase agreement. The value of the purchased
securities, including accrued interest, will at all times equal or exceed the
value of the repurchase agreement.

      Repurchase agreements pose certain risks for all entities, including the
Series, that utilize them. Such risks are not unique to the Series but are
inherent in repurchase agreements. The Series seek to minimize such risks by,
among others, the means indicated below, but because of the inherent legal
uncertainties involved in repurchase agreements, such risks cannot be
eliminated.

      For purposes of the Investment Company Act of 1940, as amended (the
"Act"), and generally, for tax purposes, a repurchase agreement is deemed to be
a loan from the Series to the seller of the Obligation. It is not clear whether
for other purposes a court would consider the Obligation purchased by the Series
subject to a repurchase agreement as being owned by the Series or as being
collateral for a loan by the Series to the seller.

      If, in the event of bankruptcy or insolvency proceedings against the
seller of the Obligation, a court holds that the Series does not have a
perfected security interest in the Obligation, the Series may be required to
return the Obligation to the seller's estate and be treated as an unsecured
creditor of the seller. As an unsecured creditor, a Series would be at risk of
losing some or all of the principal and income involved in the transaction. To
minimize this risk, 


                                      -3-
<PAGE>
 
the Series utilize custodians and subcustodians that the Investment Adviser
believes follow customary securities industry practice with respect to
repurchase agreements, and the Investment Adviser analyzes the creditworthiness
of the obligor, in this case the seller of the Obligation. But because of the
legal uncertainties, this risk, like others associated with repurchase
agreements, cannot be eliminated.

      Also, in the event of commencement of bankruptcy or insolvency proceedings
with respect to the seller of the Obligation before repurchase of the Obligation
under a repurchase agreement, a Series may encounter delay and incur costs
before being able to sell the security. Such a delay may involve loss of
interest or a decline in the price of the Obligation.

      Apart from risks associated with bankruptcy or insolvency proceedings,
there is also the risk that the seller may fail to repurchase the security.
However, if the market value of the Obligation subject to the repurchase
agreement becomes less than the repurchase price (including accrued interest),
the Series will direct the seller of the Obligation to deliver additional
securities so that the market value of all securities subject to the repurchase
agreement equals or exceeds the repurchase price.

      Each Series may not invest in repurchase agreements maturing in more than
seven days and securities which are not readily marketable if, as a result
thereof, more than 10% of the net assets of that Series (taken at market value)
would be invested in such investments. Certain repurchase agreements which
mature in more than seven days can be liquidated before the nominal fixed term
on seven days or less notice. Such repurchase agreements will be regarded as
liquid instruments.

      In addition, each Series (other than the ILA Treasury Instruments
Portfolio and FS Treasury Instruments Fund), together with other registered
investment companies having management agreements with the Investment Adviser or
any of its affiliates, may transfer uninvested cash balances into a single joint
account, the daily aggregate balance of which will be invested in one or more
repurchase agreements.

Foreign Securities

      The ILA Money Market Portfolio, FS Money Market Fund and FS Premium Fund
may invest in foreign securities and in certificates of deposit, bankers'
acceptances and fixed time deposits and other obligations issued by major
foreign banks which have more than $1 billion in total assets at the time of
purchase, foreign branches of U.S. banks, U.S. branches of foreign banks and
foreign branches of foreign banks. The FS Prime Obligations Fund may invest in
certificates of deposit, bankers' acceptances and fixed time deposits and other
obligations issued by U.S. branches of foreign banks. The ILA Tax-Exempt
Diversified Portfolio, ILA Tax-Exempt California Portfolio, ILA Tax-Exempt New
York Portfolio, FS Tax-Free Fund and FS Municipal Fund may also invest in
municipal instruments backed by letters of credit issued by certain of such
banks. Under current Securities and Exchange Commission ("SEC") rules relating
to the use of the amortized cost method of portfolio securities valuation, the
ILA Money Market Portfolio, FS Money Market Fund and FS Premium Fund are
restricted to purchasing 


                                      -4-
<PAGE>
 
U.S. dollar denominated securities, but it is not otherwise precluded from
purchasing securities of foreign issuers.

      Investments in foreign securities and bank obligations may involve
considerations different from investments in domestic securities due to limited
publicly available information; non-uniform accounting standards; the possible
imposition of withholding or confiscatory taxes; the possible adoption of
foreign governmental restrictions affecting the payment of principal and
interest; expropriation; or other adverse political or economic developments. In
addition, it may be more difficult to obtain and enforce a judgment against a
foreign issuer or a foreign branch of a domestic bank.

Asset-Backed and Receivables-Backed Securities

      The ILA Prime Obligations Portfolio, ILA Money Market Portfolio, FS Prime
Obligations Fund, FS Money Market Fund and FS Premium Fund may invest in
asset-backed and receivables-backed securities. Asset-backed and
receivables-backed securities represent participations in, or are secured by and
payable from, pools of assets such as motor vehicle installment sale contracts,
installment loan contracts, leases of various types of real and personal
property, receivables from revolving credit (credit card) agreements, corporate
receivables and other categories of receivables. Such asset pools are
securitized through the use of privately-formed trusts or special purpose
vehicles. Payments or distributions of principal and interest may be guaranteed
up to certain amounts and for a certain time period by a letter of credit or a
pool insurance policy issued by a financial institution or other credit
enhancements may be present. The value of a Series' investments in asset-backed
and receivables-backed securities may be adversely affected by prepayment of the
underlying obligations. In addition, the risk of prepayment may cause the value
of these investments to be more volatile than a Series' other investments.

      Through the use of trusts and special purpose corporations, various types
of assets, including automobile loans, computer leases, trade receivables and
credit card receivables, are being securitized in pass-through structures
similar to the mortgage pass-through structures. Consistent with their
respective investment objectives and policies, the Series may invest in these
and other types of asset-backed securities that may be developed in the future.
This Statement of Additional Information will be amended or supplemented as
necessary to reflect the ILA Prime Obligations Portfolio, ILA Money Market
Portfolio, FS Prime Obligations Fund, FS Money Market Fund and FS Premium Fund
intention to invest in asset-backed securities with characteristics that are
materially different from the securities described in the preceding paragraph.
However, a Series will generally not invest in an asset-backed security if the
income received with respect to its investment constitutes rental income or
other income not treated as qualifying income under the 90% test described in
"Tax Information" below. In general, the collateral supporting these securities
is of shorter maturity than mortgage loans and is less likely to experience
substantial prepayments in response to interest rate fluctuations.

      As set forth below, several types of asset-backed and receivables-backed
securities have already been offered to investors, including for example,
Certificates for Automobile 


                                      -5-
<PAGE>
 
Receivables(sm) ("CARS(sm)") and interests in pools of credit card receivables.
CARS(sm) represent undivided fractional interests in a trust ("CAR Trust") whose
assets consist of a pool of motor vehicle retail installment sales contracts and
security interests in the vehicles securing the contracts. Payments of principal
and interest on CARS(sm) are passed through monthly to certificate holders, and
are guaranteed up to certain amounts and for a certain time period by a letter
of credit issued by a financial institution unaffiliated with the trustee or
originator of the CAR Trust. An investor's return on CARS(sm) may be affected by
early prepayment of principal on the underlying vehicle sales contracts. If the
letter of credit is exhausted, the CAR Trust may be prevented from realizing the
full amount due on a sales contract because of state law requirements and
restrictions relating to foreclosure sales of vehicles and the obtaining of
deficiency judgments following such sales or because of depreciation, damage or
loss of a vehicle, the application of federal and state bankruptcy and
insolvency laws, or other factors. As a result, certificate holders may
experience delays in payments or losses if the letter of credit is exhausted.

      Asset-backed securities present certain risks that are not presented by
mortgage-backed securities. Primarily, these securities may not have the benefit
of any security interest in the related assets. Credit card receivables are
generally unsecured and the debtors are entitled to the protection of a number
of state and federal consumer credit laws, many of which give such debtors the
right to set off certain amounts owed on the credit cards, thereby reducing the
balance due. There is the possibility that recoveries on repossessed collateral
may not, in some cases, be available to support payments on these securities.

      Asset-backed securities are often backed by a pool of assets representing
the obligations of a number of different parties. To lessen the effect of
failures by obligors on underlying assets to make payments, the securities may
contain elements of credit support which fall into two categories: (i) liquidity
protection, and (ii) protection against losses resulting from ultimate default
by an obligor or servicer. Liquidity protection refers to the provision of
advances, generally by the entity administering the pool of assets, to ensure
that the receipt of payments on the losses results from payment of the insurance
obligations on at least a portion of the assets in the pool. This protection may
be provided through guarantees, policies or letters of credit obtained by the
issuer or sponsor from third parties, through various means of structuring the
transactions or through a combination of such approaches. The degree of credit
support provided for each issue is generally based on historical information
reflecting the level of credit risk associated with the underlying assets.
Delinquency or loss in excess of that anticipated or failure of the credit
support could adversely affect the value of or return on an investment in such a
security.

      The availability of asset-backed securities may be affected by legislative
or regulatory developments. It is possible that such developments could require
the ILA Prime Obligations Portfolio, ILA Money Market Portfolio, FS Prime
Obligations Fund, FS Money Market Fund and FS Premium Fund to dispose of any
then existing holdings of such securities.

      To the extent consistent with its investment objectives and policies, each
of the ILA Prime Obligations Portfolio, Money Market Portfolio, FS Prime
Obligations Fund, FS Money 


                                      -6-
<PAGE>
 
Market Fund and FS Premium Fund may invest in new types of mortgage related
securities and in other asset-backed securities that may be developed in the
future.

Forward Commitments and When-Issued Securities

      Each Series may purchase securities on a when-issued basis or purchase or
sell securities on a forward commitment basis. These transactions involve a
commitment by the Series to purchase or sell securities at a future date. The
price of the underlying securities (usually expressed in terms of yield) and the
date when the securities will be delivered and paid for (the settlement date)
are fixed at the time the transaction is negotiated. When-issued purchases and
forward commitment transactions are negotiated directly with the other party,
and such commitments are not traded on exchanges, but may be traded
over-the-counter.

      A Series will purchase securities on a when-issued basis or purchase or
sell securities on a forward commitment basis only with the intention of
completing the transaction and actually purchasing or selling the securities. If
deemed advisable as a matter of investment strategy, however, a Series may
dispose of or renegotiate a commitment after entering into it. A Series also may
sell securities it has committed to purchase before those securities are
delivered to the Series on the settlement date. The Series may realize a capital
gain or loss in connection with these transactions; distributions from any net
capital gains would be taxable to its unitholders. For purposes of determining a
Series' average dollar weighted maturity, the maturity of when-issued or forward
commitment securities will be calculated from the commitment date.

      When a Series purchases securities on a when-issued or forward commitment
basis, the Series will segregate cash or liquid assets having a value
(determined daily) at least equal to the amount of the Series' purchase
commitments. Alternatively, a Series may enter into off-setting contracts for
the forward sale of other securities that it owns. In the case of a forward
commitment to sell portfolio securities subject to such commitment, the Series
will segregate the portfolio securities while the commitment is outstanding.
These procedures are designed to ensure that the Series will maintain sufficient
assets at all times to cover its obligations under when-issued purchases and
forward commitments.

Variable Amount Master Demand Notes

      Each Series (other than the ILA Treasury Obligations Portfolio, ILA
Federal Portfolio, ILA Treasury Instruments Portfolio, FS Treasury Obligations
Fund, FS Federal Fund and FS Treasury Instruments Fund) may purchase variable
amount master demand notes. These obligations permit the investment of
fluctuating amounts at varying rates of interest pursuant to direct arrangements
between a Series, as lender, and the borrower. Variable amount master demand
notes are direct lending arrangements between the lender and borrower and are
not generally transferable, nor are they ordinarily rated. A Series may invest
in them only if the Investment Adviser believes that the notes are of comparable
quality to the other obligations in which that Series may invest.


                                      -7-
<PAGE>
 
Variable Rate and Floating Rate Obligations

      The interest rates payable on certain fixed income securities in which a
Series may invest are not fixed and may fluctuate based upon changes in market
rates. A variable rate obligation has an interest rate which is adjusted at
predesignated periods in response to changes in the market rate of interest on
which the interest rate is based. Variable and floating rate obligations are
less effective than fixed rate instruments at locking in a particular yield.
Nevertheless, such obligations may fluctuate in value in response to interest
rate changes if there is a delay between changes in market interest rates and
the interest reset date for the obligation.

      Each Series (other than the ILA Treasury Obligations Portfolio, ILA
Federal Portfolio, ILA Treasury Instruments Portfolio, FS Treasury Obligations
Fund, FS Federal Fund and FS Treasury Instruments Fund) may purchase variable
and floating rate demand instruments that are tax exempt municipal obligations
or other debt securities issued by corporations and other non-governmental
issuers that possess a floating or variable interest rate adjustment formula.
These instruments permit a Series to demand payment of the principal balance
plus unpaid accrued interest upon a specified number of days' notice to the
issuer or its agent. The demand feature may be backed by a bank letter of credit
or guarantee issued with respect to such instrument.

      The terms of the variable or floating rate demand instruments that a
Series may purchase provide that interest rates are adjustable at intervals
ranging from daily up to six months, and the adjustments are based upon current
market levels, the prime rate of a bank or other appropriate interest rate
adjustment index as provided in the respective instruments. Some of these
instruments are payable on demand on a daily basis or on not more than seven
days' notice. Others, such as instruments with quarterly or semiannual interest
rate adjustments, may be put back to the issuer on designated days on not more
than thirty days' notice. Still others are automatically called by the issuer
unless the Series instructs otherwise. The Trust, on behalf of the Series,
intends to exercise the demand only (1) upon a default under the terms of the
debt security, (2) as needed to provide liquidity to a Series, (3) to maintain
the respective quality standards of a Series' investment portfolio, or (4) to
attain a more optimal portfolio structure. A Series will determine the variable
or floating rate demand instruments that it will purchase in accordance with
procedures approved by the Trustees to minimize credit risks. To be eligible for
purchase by a Series, a variable or floating rate demand instrument which is
unrated must have high quality characteristics similar to other obligations in
which the Series may invest. The Investment Adviser may determine that an
unrated variable or floating rate demand instrument meets a Series' quality
criteria by reason of being backed by a letter of credit, guarantee, or demand
feature issued by an entity that meets the quality criteria for the Series.
Thus, either the credit of the issuer of the obligation or the provider of the
credit support or both will meet the quality standards of the Series.

      As stated in the Prospectuses, the Series may consider the maturity of a
long-term variable or floating rate demand instrument to be shorter than its
ultimate stated maturity under specified conditions. The acquisition of variable
or floating rate demand notes for a Series must also meet the requirements of
rules issued by the SEC applicable to the use of the amortized cost method of
securities valuation. The Series will also consider the liquidity of the market
for 


                                      -8-
<PAGE>
 
variable and floating rate instruments, and in the event that such instruments
are illiquid, the Series' investments in such instruments will be subject to the
limitation on illiquid investments.

      A Series (other than ILA Treasury Obligations Portfolio, ILA Treasury
Instruments Portfolio, ILA Government Portfolio, ILA Federal Portfolio, FS
Treasury Obligations Fund, FS Government Fund, FS Treasury Instruments Fund and
FS Federal Fund) may invest in participation interests in variable or floating
rate tax-exempt obligations held by financial institutions (usually commercial
banks). Such participation interests provide the Series with a specific
undivided interest (up to 100%) in the underlying obligation and the right to
demand payment of its proportional interest in the unpaid principal balance plus
accrued interest from the financial institution upon a specific number of days'
notice. In addition, the participation interest generally is backed by an
irrevocable letter of credit or guarantee from the institution. The financial
institution usually is entitled to a fee for servicing the obligation and
providing the letter of credit.

Restricted and Other Illiquid Securities

      A Series may purchase securities that are not registered ("restricted
securities") under the Securities Act of 1933, as amended (the "1933 Act"),
including restricted securities that can be offered and sold to "qualified
institutional buyers" under Rule 144A under the 1933 Act. However, a Series will
not invest more than 10% of the value of its net assets in securities which are
illiquid, which includes fixed time deposits with a notice or demand period of
more than seven days that cannot be traded on a secondary market and restricted
securities. The Board of Trustees has adopted guidelines under which the
Investment Adviser determines and monitors the liquidity of restricted
securities subject to the oversight of the Trustees. Restricted securities
(including securities issued under Rule 144A and commercial paper issued under
Section 4(2) of the 1933 Act) which are determined to be liquid will not be
deemed to be illiquid investments for purposes of the foregoing restriction.
Since it is not possible to predict with assurance that the market for
restricted securities will continue to be liquid, the Investment Adviser will
monitor each Series' investments in these securities, focusing on such important
factors, among others, as valuation, liquidity and availability of information.
This investment practice could have the effect of increasing the level of
illiquidity in a Series to the extent that qualified institutional buyers become
for a time uninterested in purchasing these restricted securities.

Municipal Obligations

      The ILA Prime Obligations Portfolio, ILA Money Market Portfolio, ILA
Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California Portfolio, ILA
Tax-Exempt New York Portfolio, FS Prime Obligations Fund, FS Premium Fund, FS
Money Market Fund, FS Tax-Free Fund and FS Municipal Fund may invest in
municipal obligations. Municipal obligations are issued by or on behalf of
states, territories and possessions of the United States and their political
subdivisions, agencies, authorities and instrumentalities and the District of
Columbia to obtain funds for various public purposes. The interest on most of
these obligations is generally exempt from regular federal income tax. The two
principal classifications of municipal obligations are "notes" and "bonds." The
ILA Prime Obligations Portfolio, ILA Money Market Portfolio, FS 


                                      -9-
<PAGE>
 
Prime Obligations Fund, FS Money Market Fund and FS Premium Fund may invest in
municipal obligations when yields on such securities are attractive compared to
other taxable investments.

      Notes. Municipal notes are generally used to provide for short-term
capital needs and generally have maturities of one year or less. Municipal notes
include tax anticipation notes, revenue anticipation notes, bond anticipation
notes, tax and revenue anticipation notes, construction loan notes, tax-exempt
commercial paper and certain receipts for municipal obligations.

      Tax anticipation notes are sold to finance working capital needs of
municipalities. They are generally payable from specific tax revenues expected
to be received at a future date. They are frequently general obligations of the
issuer, secured by the taxing power for payment of principal and interest.
Revenue anticipation notes are issued in expectation of receipt of other types
of revenue such as federal or state aid. Tax anticipation notes and revenue
anticipation notes are generally issued in anticipation of various seasonal
revenues such as income, sales, use, and business taxes. Bond anticipation notes
are sold to provide interim financing in anticipation of long-term financing in
the market. In most cases, these monies provide for the repayment of the notes.
Tax-exempt commercial paper consists of short-term unsecured promissory notes
issued by a state or local government or an authority or agency thereof. The
Series which invest in municipal obligations may also acquire securities in the
form of custodial receipts which evidence ownership of future interest payments,
principal payments or both on certain state and local governmental and authority
obligations when, in the opinion of bond counsel, if any, interest payments with
respect to such custodial receipts are excluded from gross income for federal
income tax purposes, and in the case of the ILA Tax-Exempt California and ILA
Tax-Exempt New York Portfolios, exempt from California and New York (city and
state) personal income taxes, respectively. Such obligations are held in custody
by a bank on behalf of the holders of the receipts. These custodial receipts are
known by various names, including "Municipal Receipts" ("MRs") and "Municipal
Certificates of Accrual on Tax-Exempt Securities" ("M-CATS"). There are a number
of other types of notes issued for different purposes and secured differently
from those described above.

      Bonds. Municipal bonds, which generally meet longer term capital needs and
have maturities of more than one year when issued, have two principal
classifications, "general obligation" bonds and "revenue" bonds.

      General obligation bonds are issued by entities such as states, counties,
cities, towns and regional districts and are used to fund a wide range of public
projects including the construction or improvement of schools, highways and
roads, water and sewer systems and a variety of other public purposes. The basic
security of general obligation bonds is the issuer's pledge of its faith,
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 rate or amount or special assessments.

      Revenue bonds have been issued to fund a wide variety of capital projects
including: electric, gas, water and sewer systems; highways, bridges and
tunnels; port and airport facilities; 


                                      -10-
<PAGE>
 
colleges and universities; and hospitals. The principal security for a revenue
bond is generally the net revenues derived from a particular facility or group
of facilities or, in some cases, from the proceeds of a special excise or other
specific revenue source. Although the principal security behind these bonds
varies widely, many provide additional security in the form of a debt service
reserve fund whose monies may also be used to make principal and interest
payments on the issuer's obligations. Housing finance authorities have a wide
range of security including partially or fully insured, rent subsidized and/or
collateralized mortgages, and/or the net revenues from housing or other public
projects. In addition to a debt service reserve fund, 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. Lease rental revenue bonds
issued by a state or local authority for capital projects are secured by annual
lease rental payments from the state or locality to the authority sufficient to
cover debt service on the authority's obligations.

      Private activity bonds (a term that includes certain types of bonds the
proceeds of which are used to a specified extent for the benefit of persons
other than governmental units), although nominally issued by municipal
authorities, are generally not secured by the taxing power of the municipality
but are secured by the revenues of the authority derived from payments by the
industrial user. Each Series (other than the ILA Treasury Obligations Portfolio,
ILA Treasury Instruments Portfolio, ILA Government Portfolio, ILA Federal
Portfolio, FS Treasury Obligations Fund, FS Treasury Instruments Fund, FS
Government and FS Federal Funds) may invest in private activity bonds. The FS
Municipal Fund may invest up to 100% of its assets in private activity bonds.
The ILA Tax-Exempt New York Portfolio will limit its investments in private
activity bonds to not more than 20% of its net assets under normal market
conditions. The ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio and FS Tax-Free Fund do not intend to invest in private activity bonds
if the interest from such bonds would be an item of tax preference to
unitholders under the federal alternative minimum tax. If such policy should
change in the future, such investments would not exceed 20% of the net assets of
each of the ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio and the FS Tax-Free Fund under normal market conditions. The ILA
Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California Portfolio, ILA
Tax-Exempt New York Portfolio, FS Tax-Free Fund and FS Municipal Fund do not
intend to invest more than 25% of the value of their respective total assets in
private activity bonds or similar obligations where non-governmental entities
supplying the revenues from which such bonds or obligations are to be paid are
in the same industry.

      Municipal bonds with a series of maturity dates are called serial bonds.
The serial bonds which the Series may purchase are limited to short-term serial
bonds---those with original or remaining maturities of thirteen months or less.
The Series may purchase long-term bonds provided that they have a remaining
maturity of thirteen months or less or, in the case of bonds called for
redemption, the date on which the redemption payment must be made is within
thirteen months. The Series may also purchase long-term bonds (sometimes
referred to as "Put Bonds"), which are subject to a Series' commitment to put
the bond back to the issuer at par at a designated time within thirteen months
and the issuer's commitment to so purchase the bond at such price and time.


                                      -11-
<PAGE>
 
      The Series which invest in municipal obligations may invest in tender
option bonds. A tender option bond is a municipal obligation (generally held
pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-term
tax-exempt rates. The bond is typically issued in conjunction with the agreement
of a third party, such as a bank, broker-dealer or other financial institution,
pursuant to which such institution grants the security holder the option, at
periodic intervals, to tender its securities to the institution and receive the
face value thereof. As consideration for providing the option, the financial
institution receives periodic fees equal to the difference between the bond's
fixed coupon rate and the rate, as determined by a remarketing or similar agent
at or near the commencement of such period, that would cause the bond, coupled
with the tender option, to trade at par on the date of such determination. Thus,
after payment of this fee, the security holder effectively holds a demand
obligation that bears interest at the prevailing short-term, tax- exempt rate.
However, an institution will not be obligated to accept tendered bonds in the
event of certain defaults by, or a significant downgrading in the credit rating
assigned to, the issuer of the bond.

      The tender option will be taken into consideration in determining the
maturity of tender option bonds and the average portfolio maturity of a Series.
The liquidity of a tender option bond is a function of the credit quality of
both the bond issuer and the financial institution providing liquidity.
Consequently, tender option bonds are deemed to be liquid unless, in the opinion
of the Investment Adviser, the credit quality of the bond issuer and the
financial institution is deemed, in light of the relevant Series' credit quality
requirements, to be inadequate.

      Although the ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt
California Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-Free Fund and FS
Municipal Fund intend to invest in tender option bonds the interest on which
will, in the opinion of counsel for the issuer and sponsor or counsel selected
by the Investment Adviser, be excluded from gross income for federal income tax
purposes, there is no assurance that the Internal Revenue Service will agree
with such counsel's opinion in any particular case. Consequently, there is a
risk that a Series will not be considered the owner of such tender option bonds
and thus will not be entitled to treat such interest as exempt from such tax. A
similar risk exists for certain other investments subject to puts or similar
rights. Additionally, the federal income tax treatment of certain other aspects
of these investments, including the proper tax treatment of tender options and
the associated fees, in relation to various regulated investment company tax
provisions is unclear. The ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt
California Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-Free Fund and FS
Municipal Fund intend to manage their respective portfolios in a manner designed
to eliminate or minimize any adverse impact from the tax rules applicable to
these investments.

      In addition to general obligation bonds, revenue bonds and serial bonds,
there are a variety of hybrid and special types of municipal obligations as well
as numerous differences in the security of municipal obligations both within and
between the two principal classifications above.


                                      -12-
<PAGE>
 
      The ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-Free Fund and FS Municipal
Fund may purchase municipal instruments that are backed by letters of credit
issued by foreign banks that have a branch, agency or subsidiary in the United
States. Such letters of credit, like other obligations of foreign banks, may
involve credit risks in addition to those of domestic obligations, including
risks relating to future political and economic developments, nationalization,
foreign governmental restrictions such as exchange controls and difficulties in
obtaining or enforcing a judgment against a foreign bank (including branches).

      For the purpose of investment restrictions of the Series, the
identification of the "issuer" of municipal obligations that are not general
obligation bonds is made by the Investment Adviser on the basis of the
characteristics of the obligation as described above, the most significant of
which is the source of funds for the payment of principal of and interest on
such obligations.

      An entire issue of municipal obligations may be purchased by one or a
small number of institutional investors such as one of the Series. Thus, the
issue may not be said to be publicly offered. Unlike securities which must be
registered under the 1933 Act prior to offer and sale, municipal obligations
which are not publicly offered may nevertheless be readily marketable. A
secondary market may exist for municipal obligations which were not publicly
offered initially.

      Municipal obligations purchased for a Series may be subject to the Series'
policy on holdings of illiquid securities. The Investment Adviser determines
whether a municipal obligation is liquid based on whether it may be sold in a
reasonable time consistent with the customs of the municipal markets (usually
seven days) at a price (or interest rate) which accurately reflects its value.
The Investment Adviser believes that the quality standards applicable to each
Series' investments enhance liquidity. In addition, stand-by commitments and
demand obligations also enhance liquidity.

      Yields on municipal obligations depend on a variety of factors, including
money market conditions, municipal bond market conditions, the size of a
particular offering, the maturity of the obligation and the quality of the
issue. High quality municipal obligations tend to have a lower yield than lower
rated obligations. Municipal obligations are subject to the provisions of
bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Code, and laws, if any, which may be
enacted by Congress or state legislatures extending the time for payment of
principal or interest, or both, or imposing other constraints upon enforcement
of such obligations or municipalities to levy taxes. There is also the
possibility that as a result of litigation or other conditions the power or
ability of any one or more issuers to pay when due principal of and interest on
its or their municipal obligations may be materially affected.

Investing in California

      The financial condition of the State of California ("California"), its
public authorities and local governments could affect the market values and
marketability of, and therefore the net asset value per unit and the interest
income of, the ILA Tax-Exempt California Portfolio, or result in 


                                      -13-
<PAGE>
 
the default of existing obligations, including obligations which may be held by
the ILA Tax-Exempt California Portfolio. The following section provides only a
brief summary of the complex factors affecting the financial condition of
California, and is based on information obtained from California, as publicly
available prior to the date of this Statement of Additional Information. The
information contained in such publicly available documents has not been
independently verified. It should be noted that the creditworthiness of
obligations issued by local issuers may be unrelated to the creditworthiness of
California, and that there is no obligation on the part of California to make
payment on such local obligations in the event of default in the absence of a
specific guarantee or pledge provided by California.

      During the early 1990's, California experienced significant financial
difficulties, which reduced its credit standing, but the State's finances have
improved significantly since 1994, with ratings increases since 1996. The
ratings of certain related debt of other issuers for which California has an
outstanding lease purchase, guarantee or other contractual obligation (such as
for state-insured hospital bonds) are generally linked directly to California's
rating. Should the financial condition of California deteriorate again, its
credit ratings could be reduced, and the market value and marketability of all
outstanding notes and bonds issued by California, its public authorities or
local governments could be adversely affected.

Economic Factors

      California's economy is the largest among the 50 states and one of the
largest in the world. The State's population of almost 34 million represents
over 12% of the total United States population and grew by 26% in the 1980's,
more than double the national rate. Population growth slowed to less than 1%
annually in 1994 and 1995, but rose to 1.8% in 1996 and 1.6% in 1997. During the
early 1990's, net population growth in the State was due to births and foreign
immigration, but in recent years, in-migration from the other states has
increased.

      Total personal income in the State, at an estimated $846 billion in 1997,
accounts for almost 13% of all personal income in the nation. Total employment
is over 15 million, the majority of which is in the service, trade and
manufacturing sectors.

      From mid-1990 to late 1993, the State suffered a recession with the worst
economic, fiscal and budget conditions since the 1930's. Construction,
manufacturing (especially aerospace), and financial services, among others, were
all severely affected, particularly in Southern California. Employment levels
stabilized by late 1993 and pre-recession job levels were reached in 1996.
Unemployment, while remaining higher than the national average, has come down
from its 10% recession peak to under 6% in early 1999. Economic indicators show
a steady and strong recovery underway in California since the start of 1994
particularly in high technology manufacturing and services, including computer
software, electronic manufacturing and motion picture/television production, and
other services, entertainment and tourism, and both residential and commercial
construction. The Asian economic crisis beginning in mid-1997 has significantly
reduced exports to that region, although this has been offset by increased
exports to Latin America and other areas. Overall, the Asian crisis is expected
to have a moderate 


                                      -14-
<PAGE>
 
dampening effect on the State's economy, but the economy is still expected to
outpace the nation in 1999. Any delay or reversal of the recovery may create new
shortfalls in State revenues.

Constitutional Limitations on Taxes, Other Charges and Appropriations

      Limitation on Property Taxes. Certain California Municipal Obligations may
be obligations of issuers which rely in whole or in part, directly or
indirectly, on ad valorem property taxes as a source of revenue. The taxing
powers of California local governments and districts are limited by Article
XIIIA of the California Constitution, enacted by the voters in 1978 and commonly
known as "Proposition 13." Briefly, Article XIIIA limits to 1% of full cash
value of the rate of ad valorem property taxes on real property and generally
restricts the reassessment of property to 2% per year, except under new
construction or change of ownership (subject to a number of exemptions). Taxing
entities may, however, raise ad valorem taxes above the 1% limit to pay debt
service on voter-approved bonded indebtedness.

      Under Article XIIIA, the basic 1% ad valorem tax levy is applied against
the assessed value of property as of the owner's date of acquisition (or as of
March 1, 1975, if acquired earlier), subject to certain adjustments. This system
has resulted in widely varying amounts of tax on similarly situated properties.
Several lawsuits have been filed challenging the acquisition-based assessment
system of Proposition 13, but it was upheld by the U.S. Supreme Court in 1992.

      Article XIIIA prohibits local governments from raising revenues through ad
valorem taxes above the 1% limit; it also requires voters of any governmental
unit to give two-thirds approval to levy any "special tax." Court decisions,
however, allowed a non-voter approved levy of "general taxes" which were not
dedicated to a specific use.

      Limitations on Other Taxes, Fees and Charges. On November 5, 1996, the
voters of the State approved Proposition 218, called the "Right to Vote on Taxes
Act." Proposition 218 added Articles XIIIC and XIIID to the State Constitution,
which contain a number of provisions affecting the ability of local agencies to
levy and collect both existing and future taxes, assessments, fees and charges.

      Article XIIIC requires that all new or increased local taxes be submitted
to the electorate before they become effective. Taxes for general governmental
purposes require a majority vote and taxes for specific purposes require a
two-thirds vote. Further, any general purpose tax which was imposed, extended or
increased without voter approval after December 31, 1994 must be approved by a
majority vote within two years.

      Article XIIID contains several new provisions making it generally more
difficult for local agencies to levy and maintain "assessments" for municipal
services and programs. Article XIIID also contains several new provisions
affecting "fees" and "charges", defined for purposes of Article XIIID to mean
"any levy other than an ad valorem tax, a special tax, or an assessment, imposed
by a [local government] upon a parcel or upon a person as an incident of
property ownership, including a user fee or charge for a property related
service." All new and existing 


                                      -15-
<PAGE>
 
property related fees and charges must conform to requirements prohibiting,
among other things, fees and charges which generate revenues exceeding the funds
required to provide the property related service or are used for unrelated
purposes. There are new notice, hearing and protest procedures for levying or
increasing property related fees and charges, and, except for fees or charges
for sewer, water and refuse collection services (or fees for electrical and gas
service, which are not treated as "property related" for purposes of Article
XIIID), no property related fee or charge may be imposed or increased without
majority approval by the property owners subject to the fee or charge or, at the
option of the local agency, two-thirds voter approval by the electorate residing
in the affected area.

      In addition to the provisions described above, Article XIIIC removes
limitations on the initiative power in matters of local taxes, assessments, fees
and charges. Consequently, local voters could, by future initiative, repeal,
reduce or prohibit the future imposition or increase of any local tax,
assessment, fee or charge. It is unclear how this right of local initiative may
be used in cases where taxes or charges have been or will be specifically
pledged to secure debt issues.

      The interpretation and application of Proposition 218 will ultimately be
determined by the courts with respect to a number of matters, and it is not
possible at this time to predict with certainty the outcome of such
determinations. Proposition 218 is generally viewed as restricting the fiscal
flexibility of local governments, and for this reason, some ratings of
California cities and counties have been, and others may be, reduced.

      Appropriations Limits. The State and its local governments are subject to
an annual "appropriations limit" imposed by Article XIIIB of the California
Constitution, enacted by the voters in 1979 and significantly amended by
Propositions 98 and 111 in 1988 and 1990, respectively. Article XIIIB prohibits
the State or any covered local government from spending "appropriations subject
to limitation" in excess of the appropriations limit imposed. "Appropriations
subject to limitation" are authorizations to spend "proceeds of taxes," which
consist of tax revenues and certain other funds, including proceeds from
regulatory licenses, user charges or other fees, to the extent that such
proceeds exceed the cost of providing the product or service, but "proceeds of
taxes" exclude most State subventions to local governments. No limit is imposed
on appropriations of funds which are not "proceeds of taxes," such as reasonable
user charges or fees, and certain other non-tax funds, including bond proceeds.

      Among the expenditures not included in the Article XIIIB appropriations
limit are (1) the debt service cost of bonds issued or authorized prior to
January 1, 1979, or subsequently authorized by the voters, (2) appropriations
arising from certain emergencies declared by the Governor, (3) appropriations
for certain capital outlay projects, (4) appropriations by the State of
post-1989 increases in gasoline taxes and vehicle weight fees, and (5)
appropriations made in certain cases of emergency.

      The appropriations limit for each year is adjusted annually to reflect
changes in cost of living and population, and any transfers of service
responsibilities between government units. 


                                      -16-
<PAGE>
 
The definitions for such adjustments were liberalized in 1990 to follow more
closely growth in the State's economy.

      "Excess" revenues are measured over a two year cycle. Local governments
must return any excess to taxpayers by rate reductions. The State must refund
50% of any excess, with the other 50% paid to schools and community colleges.
With more liberal annual adjustment factors since 1988, and depressed revenues
since 1990 because of the recession, few governments are currently operating
near their spending limits, but this condition may change over time. Local
governments may by voter approval exceed their spending limits for up to four
years. During fiscal year 1986-87, State receipts from proceeds of taxes
exceeded its appropriations limit by $1.1 billion, which was returned to
taxpayers. Since that year, appropriations subject to limitation have been under
the State limit. State appropriations were $6.8 billion under the limit for
fiscal year 1998-99.

      Because of the complex nature of Articles XIIIA, XIIIB, XIIIC and XIIID of
the California Constitution, the ambiguities and possible inconsistencies in
their terms, and the impossibility of predicting future appropriations or
changes in population and cost of living, and the probability of continuing
legal challenges, it is not currently possible to determine fully the impact of
these Articles on California municipal obligations or on the ability of the
State or local governments to pay debt service on such California municipal
obligations. It is not possible, at the present time, to predict the outcome of
any pending litigation with respect to the ultimate scope, impact or
constitutionality of these Articles or the impact of any such determinations
upon State agencies or local governments, or upon their ability to pay debt
service on their obligations. Further initiatives or legislative changes in laws
or the California Constitution may also affect the ability of the State or local
issuers to repay their obligations.

Obligations of the State of California

      Under the California Constitution, debt service on outstanding general
obligation bonds is the second charge to the General Fund after support of the
public school system and public institutions of higher education. As of February
1, 1999, the State had outstanding approximately $19.2 billion of long-term
general obligation bonds, plus $484 million of general obligation commercial
paper which will be refunded by long-term bonds in the future, and $6.7 billion
of lease-purchase debt supported by the State General Fund. The State also had
about $15.8 billion of authorized and unissued long-term general obligation
bonds and lease-purchase debt. In FY 1997-98, debt service on general obligation
bonds and lease purchase debt was approximately 4.4% of General Fund revenues.

Recent Financial Results

      The principal sources of General Fund revenues in 1996-1997 were the
California personal income tax (47% of total revenues), the sales tax (34%),
bank and corporation taxes (12%), and the gross premium tax on insurance (2%).
The State maintains a Special Fund for Economic Uncertainties (the "SFEU"),
derived from General Fund revenues, as a reserve to meet cash needs of the
General Fund, but which is required to be replenished as soon as sufficient


                                      -17-
<PAGE>
 
revenues are available. Year-end balances in the SFEU are included for financial
reporting purposes in the General Fund balance. Because of the recession and an
accumulated budget deficit, no reserve was budgeted in the SFEU from 1992-93 to
1995-96.

      General. Throughout the 1980's, State spending increased rapidly as the
State population and economy also grew rapidly, including increased spending for
many assistance programs to local governments, which were constrained by
Proposition 13 and other laws. The largest State program is assistance to local
public school districts. In 1988, an initiative (Proposition 98) was enacted
which (subject to suspension by a two-thirds vote of the Legislature and the
Governor) guarantees local school districts and community college districts a
minimum share of State General Fund revenues (currently about 35%).

      Recent Budgets. As a result of the severe economic recession from 1990-94
and other factors, the State experienced substantial revenue shortfalls, and
greater than anticipated social service costs, in the early 1990's. The State
accumulated and sustained a budget deficit in the budget reserve, the SFEU,
approaching $2.8 billion at its peak at June 30, 1993. The Legislature and
Governor agreed on a number of different steps to respond to the adverse
financial conditions and produce Budget Acts in the Years 1991-92 to 1994-95
(although not all of these actions were taken in each year):

      o     significant cuts in health and welfare program expenditures;

      o     transfers of program responsibilities and some funding sources from
            the State to local governments, coupled with some reduction in
            mandates on local government;

      o     transfer of about $3.6 billion in annual local property tax revenues
            from cities, counties, redevelopment agencies and some other
            districts to local school districts, thereby reducing State funding
            for schools;

      o     reduction in growth of support for higher education programs,
            coupled with increases in student fees;

      o     revenue increases (particularly in the 1992-93 Fiscal Year budget),
            most of which were for a short duration;

      o     increased reliance on aid from the federal government to offset the
            costs of incarcerating, educating and providing health and welfare
            services to undocumented aliens (although these efforts have
            produced much less federal aid than the State Administration had
            requested); and

      o     various one-time adjustments and accounting changes (some of which
            have been challenged in court and reversed).


                                      -18-

      A consequence of the accumulated budget deficits in the early 1990's,
together with other factors such as disbursement of funds to local school
districts "borrowed" from future fiscal years and hence not shown in the annual
budget, was to significantly reduce the State's cash resources available to pay
its ongoing obligations. The State's cash condition became so serious that from
late spring 1992 until 1995, the State had to rely on issuance of short term
notes which matured in a subsequent fiscal year to finance its ongoing deficit,
and pay current obligations. For a two-month period in the summer of 1992,
pending adoption of the annual Budget Act, the State was forced to issue
registered warrants (IOUs) to some of its suppliers, employees and other
creditors. The last of these deficit notes was repaid in April, 1996.

      The State's financial condition improved markedly during the 1995-96,
1996-97 and 1997-98 fiscal years, with a combination of better than expected
revenues, slowdown in growth of social welfare programs, and continued spending
restraint based on the actions taken in earlier years. The State's cash position
also improved, and no external deficit borrowing has occurred over the end of
these three fiscal years.

      The economy grew strongly during these fiscal years, and as a result, the
General Fund took in substantially greater tax revenues (around $2.2 billion in
1995-96, $1.6 billion in 1996-97 and $2.1 billion in 1997-98) than were
initially planned when the budgets were enacted. These additional funds were
largely directed to school spending as mandated by Proposition 98, and to make
up shortfalls from reduced federal health and welfare aid in 1995-96 and
1996-97. The accumulated budget deficit from the recession years was finally
eliminated. The Department of Finance estimates that the State's budget reserve
(the SFEU) totaled about $400 million as of June 30, 1997 and $1.8 billion at
June 30, 1998.

      FY 1997-98 Budget. In May 1997, the California Supreme Court ruled that
the State had acted illegally in 1993 and 1994 by using a deferral of payments
to the Public Employees Retirement Fund to help balance earlier budgets. In
response to this court decision, the Governor ordered an immediate repayment to
the Retirement Fund of about $1.235 billion, which was made in late July, 1997,
and substantially "used up" the then-expected additional General Fund revenues
for the fiscal year. The 1997-98 Budget Act provided another year of rapidly
increasing funding for K-14 public education. Support for higher education units
in the State also increased by about 6 percent. Because of the pension payment,
most other State programs were funded at levels consistent with prior years, and
several initiatives had to be dropped. The final results for FY 1997-98 showed
General Fund revenues and transfers of $54.7 billion and expenditures of $53.3
billion.

      Part of the 1997-98 Budget Act was completion of State welfare reform
legislation to implement the new federal law passed in 1996. The new State
program, called "CalWORKs," became effective January 1, 1998, and emphasizes
programs to bring aid recipients into the workforce. As required by federal law,
new time limits are placed on receipt of welfare aid.

      FY 1998-99 Budget. The FY 1998-99 Budget Act was signed on August 21,
1998. After giving effect to line-item vetoes made by the Governor, the Budget
plan resulted in spending of 


                                      -19-
<PAGE>
 
about $57.3 billion for the General Fund and $14.7 billion for Special Funds.
The Budget Act assumed General Fund revenues and transfers in FY 1998-99 of
$57.0 billion. After enactment of the Budget Act, the Legislature passed a
number of additional fiscal bills, which resulted in a net increase of
expenditures of about $250 million, but the Administration also raised its
estimate of revenues from the 1997-98 fiscal year. In total, the Administration
projected in September, 1998 that the balance in the SFEU at June 30, 1999 would
be about $1.2 billion.

      The Administration released new projections for the balance of FY 1998-99
on January 8, 1999 as part of the Governor's Proposed Budget for 1999-2000 (the
"Governor's Budget"). As a result of somewhat slower economic growth largely due
to the Asian economic slowdown resulting in reduced revenues, and higher health
and welfare caseloads than projected, the Administration projected that the SFEU
would be reduced to about $600 million as of June 30, 1999. However, a later
report in February, 1999 from the State Legislative Analyst stated that economic
activity in the State appeared to be stronger in late 1998 than the Governor's
Budget predicted, and revenues for 1998-99 could be as much as $750 million
higher than projected by the Governor's Budget.

      As has been the case in the last several years, spending on K-12 education
increased significantly, by a total of $2.2 billion, with projected per-pupil
spending of $5,695, more than one-third higher than the per-pupil spending
during the last recession year of 1993-94. Funding to support higher education
was also increased significantly (15% for the University of California and 14%
for the California State University system). The Budget included some increases
in health and welfare programs, including the first increase in the monthly
welfare grant since levels were cut during the recession.

      One of the most important elements of the 1998-99 Budget Act was agreement
on substantial tax cuts. The largest of these is a phased-in cut in the Vehicle
License Fee (an annual tax on the value of cars registered in the State, the
"VLF"). Starting in 1999, the VLF is reduced by 25%. Under current law, VLF
funds are automatically transferred to cities and counties, so the new
legislation provides for the General Fund to make up the reductions. If State
General Fund revenues continue to grow above certain targeted levels in future
years (a development which appears unlikely given more recent revenue
projections), the cut could reach as much as 67.5% by the year 2003. The initial
25% VLF cut will be offset by about $500 million in General Fund money in FY
1998-99, and $1 billion for future years. Other tax cuts in FY 1998-99 include
an increase in the dependent credit exemption for personal income tax filers,
restoration of a renter's tax credit for taxpayers, and a variety of business
tax relief measures. The total cost of these tax cuts is estimated at $1.4
billion for FY 1998-99.

      Although, as noted, the 1998-99 Budget Act projects a budget reserve in
the SFEU of about $1.2 billion on June 30, 1999 (since reduced in the Governor's
Budget), the General Fund fund balance on that date also reflects $1.0 billion
of "loans" which the General Fund made to local schools in the recession years,
representing cash outlays above the mandatory minimum funding level. Settlement
of litigation over these transactions in July 1996 calls for repayment of these
loans over the period ending in 2001-02, about equally split between outlays
from the 


                                      -20-
<PAGE>
 
General Fund and from schools' entitlements. The 1998-99 Budget Act contained a
$300 million appropriation from the General Fund toward this settlement.

      Proposed FY 1999-2000 Budget. The newly elected Governor, Gray Davis,
released his proposed FY 1999-00 Budget in January. It projected somewhat lower
General Fund revenues than in earlier projections, due to slower economic
growth, but totaling an estimated $60.3 billion. (This figure could be higher
based on the more recent revenue estimates from the State Legislative Analyst.)
The proposed budget assumes certain one-time revenues, receipt of the first
installment payment from the tobacco manufacturer's litigation settlement, and
increased federal aid for the cost of incarcerating illegal aliens.

      The Governor's Budget proposes expenditures of about $60.5 billion, which
would result in a balance in the SFEU at June 30, 2000 of about $400 million.
Major expenditures initiatives include increased funding and some new programs
for K-12 schools, a modest increase in funding for higher education, an increase
in certain State-funded welfare programs, combined with decreased caseloads for
Medi-Cal and CalWORKs (the replacement to the old welfare system, following the
1996 federal welfare reform law).

      Although the State's strong economy is producing record revenues to the
State government, the State's budget continues to be under stress from mandated
spending on education, a rising prison population, and social needs of a growing
population with many immigrants. These factors which limit State spending growth
also put pressure on local governments. There can be no assurances that, if
economic conditions weaken, or other factors intercede, the State will not
experience budget gaps in the future.

Bond Rating

      The ratings on California's long-term general obligation bonds were
reduced in the early 1990's from "AAA" levels which had existed prior to the
recession. After 1996, the three major rating agencies raised their ratings of
California's general obligation bonds, which as of February 1999 were assigned
ratings of "A+" from Standard & Poor's, "Aa3" from Moody's and "AA-" from Fitch.

      There can be no assurance that such ratings will be maintained in the
future. It should be noted that the creditworthiness of obligations issued by
local California issuers may be unrelated to creditworthiness of obligations
issued by the State of California, and that there is no obligation on the part
of the State to make payment on such local obligations in the event of default.

Legal Proceedings

      The State is involved in certain legal proceedings (described in the
State's recent financial statements) that, if decided against the State, may
require the State to make significant future expenditures or may substantially
impair revenues. Trial courts have recently entered tentative decisions or
injunctions which would overturn several parts of the State's recent budget
compromises. The matters covered by these lawsuits include reductions in welfare
payments and 


                                      -21-
<PAGE>
 
the use of certain cigarette tax funds for health costs. All of these cases are
subject to further proceedings and appeals, and if California eventually loses,
the final remedies may not have to be implemented in one year.

Obligations of Other Issuers

      Other Issuers of California Municipal Obligations. There are a number of
State agencies, instrumentalities and political subdivisions of the State that
issue Municipal Obligations, some of which may be conduit revenue obligations
payable from payments from private borrowers. These entities are subject to
various economic risks and uncertainties, and the credit quality of the
securities issued by them may vary considerably from the credit quality of
obligations backed by the full faith and credit of the State.

      State Assistance. Property tax revenues received by local governments
declined more than 50% following passage of Proposition 13. Subsequently, the
California Legislature enacted measures to provide for the redistribution of the
State's General Fund surplus to local agencies, the reallocation of certain
State revenues to local agencies and the assumption of certain governmental
functions by the State to assist municipal issuers to raise revenues. Total
local assistance from the State's General Fund was budgeted at approximately 75%
of General Fund expenditures in recent years, including the effect of
implementing reductions in certain aid programs. To reduce State General Fund
support for school districts, the 1992-93 and 1993-94 Budget Acts caused local
governments to transfer $3.9 billion of property tax revenues to school
districts, representing loss of the post-Proposition 13 "bailout" aid. Local
governments have in return received greater revenues and greater flexibility to
operate health and welfare programs. However, except for agreement in 1997 on a
new program for the State to substantially take over funding for local trial
courts (saving cities and counties some $400 million annually), there has been
no large-scale reversal of the property tax shift to help local government.

      To the extent the State should be constrained by its Article XIIIB
appropriations limit, or its obligation to conform to Proposition 98, or other
fiscal considerations, the absolute level, or the rate of growth, of State
assistance to local governments may continue to be reduced. Any such reductions
in State aid could compound the serious fiscal constraints already experienced
by many local governments, particularly counties. Los Angeles County, the
largest in the State, was forced to make significant cuts in services and
personnel, particularly in the health care system, in order to balance its
budget in FY1995-96 and FY1996-97. Orange County, which emerged from Federal
Bankruptcy Court protection in June 1996, has significantly reduced county
services and personnel, and faces strict financial conditions following large
investment fund losses in 1994 which resulted in bankruptcy.

      Counties and cities may face further budgetary pressures as a result of
changes in welfare and public assistance programs, which were enacted in August,
1997 in order to comply with the federal welfare reform law. Generally, counties
play a large role in the new system, and are given substantial flexibility to
develop and administer programs to bring aid recipients into the workforce.
Counties are also given financial incentives if either at the county or
statewide level, the "Welfare-to-Work" programs exceed minimum targets; counties
are also subject to financial 


                                      -22-
<PAGE>
 
penalties for failure to meet such targets. Counties remain responsible to
provide "general assistance" for able-bodied indigents who are ineligible for
other welfare programs. The long-term financial impact of the new CalWORKs
system on local governments is still unknown.

      Assessment Bonds. California Municipal Obligations which are assessment
bonds may be adversely affected by a general decline in real estate values or a
slowdown in real estate sales activity. In many cases, such bonds are secured by
land which is undeveloped at the time of issuance but anticipated to be
developed within a few years after issuance. In the event of such reduction or
slowdown, such development may not occur or may be delayed, thereby increasing
the risk of a default on the bonds. Because the special assessments or taxes
securing these bonds are not the personal liability of the owners of the
property assessed, the lien on the property is the only security for the bonds.
Moreover, in most cases the issuer of these bonds is not required to make
payments on the bonds in the event of delinquency in the payment of assessments
or taxes, except from amounts, if any, in a reserve fund established for the
bonds.

      California Long Term Lease Obligations. Based on a series of court
decisions, certain long-term lease obligations, though typically payable from
the general fund of the State or a municipality, are not considered
"indebtedness" requiring voter approval. Such leases, however, are subject to
"abatement" in the event the facility being leased is unavailable for beneficial
use and occupancy by the municipality during the term of the lease. Abatement is
not a default, and there may be no remedies available to the holders of the
certificates evidencing the lease obligation in the event abatement occurs. The
most common cases of abatement are failure to complete construction of the
facility before the end of the period during which lease payments have been
capitalized and uninsured casualty losses to the facility (e.g., due to
earthquake). In the event abatement occurs with respect to a lease obligation,
lease payments may be interrupted (if all available insurance proceeds and
reserves are exhausted) and the certificates may not be paid when due. Although
litigation is brought from time to time which challenges the constitutionality
of such lease arrangements, the California Supreme Court issued a ruling in
August, 1998 which reconfirmed the legality of these financing methods.

Other Considerations

      The repayment of industrial development securities secured by real
property may be affected by California laws limiting foreclosure rights of
creditors. Securities backed by health care and hospital revenues may be
affected by changes in State regulations governing cost reimbursements to health
care providers under Medi-Cal (the State's Medicaid program), including risks
related to the policy of awarding exclusive contracts to certain hospitals.

      Limitations on ad valorem property taxes may particularly affect "tax
allocation" bonds issued by California redevelopment agencies. Such bonds are
secured solely by the increase in assessed valuation of a redevelopment project
area after the start of redevelopment activity. In the event that assessed
values in the redevelopment project decline (e.g., because of a major natural
disaster such as an earthquake), the tax increment revenue may be insufficient
to make principal and interest payments on these bonds. Both Moody's and S&P
suspended ratings on 


                                      -23-
<PAGE>
 
California tax allocation bonds after the enactment of Articles XIIIA and XIIIB,
and only resumed such ratings on a selective basis.

      Proposition 87, approved by California voters in 1988, requires that all
revenues produced by a tax rate increase go directly to the taxing entity which
increased such tax rate to repay that entity's general obligation indebtedness.
As a result, redevelopment agencies (which, typically, are the issuers of tax
allocation securities) no longer receive an increase in tax increment when taxes
on property in the project area are increased to repay voter-approved bonded
indebtedness.

      The effect of these various constitutional and statutory changes upon the
ability of California municipal securities issuers to pay interest and principal
on their obligations remains unclear. Furthermore, other measures affecting the
taxing or spending authority of California or its political subdivisions may be
approved or enacted in the future. Legislation has been or may be introduced
which would modify existing taxes or other revenue-raising measures or which
either would further limit or, alternatively, would increase the abilities of
state and local governments to impose new taxes or increase existing taxes. It
is not possible, at present, to predict the extent to which any such legislation
will be enacted. Nor is it possible, at present, to determine the impact of any
such legislation on California Municipal Obligations in which the Fund may
invest, future allocations of state revenues to local governments or the
abilities of state or local governments to pay the interest on, or repay the
principal of, such California Municipal Obligations.

      Substantially all of California is within an active geologic region
subject to major seismic activity. Northern California in 1989 and Southern
California in 1994 experienced major earthquakes causing billions of dollars in
damages. The federal government provided more than $13 billion in aid for both
earthquakes, and neither event is expected to have any long-term negative
economic impact. Any California Municipal Obligation in the Fund could be
affected by an interruption of revenues because of damaged facilities, or,
consequently, income tax deductions for casualty losses or property tax
assessment reductions. Compensatory financial assistance could be constrained by
the inability of (i) an issuer to have obtained earthquake insurance coverage
rates; (ii) an insurer to perform on its contracts of insurance in the event of
widespread losses; or (iii) the federal or State government to appropriate
sufficient funds within their respective budget limitations.

Special Considerations Relating To New York Municipal Obligations

            Some of the significant financial considerations relating to the ILA
Tax-Exempt New York Portfolio's investments in New York Municipal Obligations
are summarized below. This summary information is not intended to be a complete
description and is principally derived from official statements relating to
issues of New York Municipal Obligations that were available prior to the date
of this Statement of Additional Information. The accuracy and completeness of
the information contained in those official statements have not been
independently verified.

State Economy. New York is the third most populous state in the nation and has a
relatively high level of personal wealth. The State's economy is diverse with a
comparatively large share of the nation's finance, insurance, transportation,
communications and services employment, and a very small share of the nation's
farming and mining activity. The State's location and its excellent air
transport facilities and natural harbors have made it an important link in
international commerce. Travel and tourism constitute an important part of the
economy. Like the rest of the nation, New York has a declining proportion of its
workforce engaged in manufacturing, and an increasing proportion engaged in
service industries.

            The State has historically been one of the wealthiest states in the
nation. For decades, however, the State has grown more slowly than the nation as
a whole, gradually eroding its relative economic position. State per capita
personal income has historically been significantly higher than the national
average, although the ratio has varied substantially. Because New York City (the
"City") is a regional employment center for a multi-state region, State personal
income measured on a residence basis understates the relative importance of the
State to the national economy and the size of the base to which State taxation
applies.

            The State economic forecast has been modified for 1999 and 2000 from
the one used in earlier updates of the Financial Plan. Continued growth is
projected in 1999 and 2000 for employment, wages, and personal income, although
the growth is expected to moderate from the 1998 pace. However, a continuation
of international financial and economic turmoil may result in a sharper slowdown
than currently projected. Personal income is estimated to have grown by 4.9
percent in 1998, fueled in part by a continued large increase in financial
sector bonus payments at the beginning of the year, and is projected to grow by
4.2 percent in 1999 and 4.0 percent in 2000. Increases in bonus payments in 1999
and 2000 are projected to be modest, a distinct shift from the torrid rate of
the last few years. Overall employment growth is anticipated to continue at a
modes rate, reflecting the slowing growth in the national economy, continued
spending restraint in governmental, and restructuring in the manufacturing,
health care, social service, and banking sectors.

            There can be no assurance that the State economy will not experience
worse-than-predicted results, with corresponding material and adverse effects on
the State's projections of receipts and disbursements.

State Budget. The State Constitution requires the governor (the "Governor") to
submit to the State legislature (the "Legislature") a balanced executive budget
which contains a complete plan of expenditures for the ensuing fiscal year and
all moneys and revenues estimated to be available therefor, accompanied by bills
containing all proposed appropriations or reappropriations and any new or
modified revenue measures to be enacted in connection with the executive budget.
The entire plan constitutes the proposed State financial plan for that fiscal
year. The Governor is required to submit to the Legislature quarterly budget
updates which include a revised cash-basis state financial plan, and an
explanation of any changes from the previous state financial plan.

            State law requires the Governor to propose a balanced budget each
year. In recent years, the State has closed projected budget gaps of $5.0
billion (1995-96), $3.9 billion (1996-


                                      -25-
<PAGE>
 
97), $2.3 billion (1997-98), and less than $1 billion (1998-99). The State, as a
part of the 1998-99 Executive Budget projections submitted to the Legislature in
February 1998, projected a 1999-2000 General Fund budget gap of approximately
$1.7 billion. The Division of the Budget ("DOB") projects budget gaps of $1.11
billion in 2000-01 and $2.08 billion in 2001-02. These estimates assume that the
Legislature will enact the 1999-2000 Executive Budget and accompanying
legislation in its entirety. The gaps also include $500 million in unspecified
annual spending efficiencies, which is comparable to the Governor's Executive
Budget assumptions in previous fiscal years. Future Financial Plans are also
likely to count on savings from efficiencies, workforce management efforts,
aggressive efforts to maximize federal and other non-General Fund resources, and
other efforts to control of State spending. Nearly all the actions proposed by
the Governor to balance the 1999-2000 Financial Plan recur and grow in value in
future years. The DOB projects that, if the projected budget gap for 2000-01 is
closed with recurring actions, the 2001-02 budget gap would be reduced to $963
million under current projections.

            Sustained growth in the State's economy could contribute to closing
projected budget gaps over the next several years, both in terms of
higher-than-projected tax receipts and in lower-than-expected entitlement
spending. However, the State's projections in 1999-2000 currently assume actions
to achieve $600 million in lower disbursements and $250 million in additional
receipts from the settlement of State claims against the tobacco industry.
Consistent with past practice, the projections do not include any costs
associated with new collective bargaining agreements after the expiration of the
current round of contracts at the end of the 1998-99 fiscal year. The State
expects that the 1990-2000 Financial Plan will achieve savings from initiatives
by State agencies to deliver services more efficiently, workforce management
efforts, maximization of federal and non-General Fund spending offsets, and
other actions necessary to bring projected disbursements and receipts into
balance.

            The State will formally update its outyear projections of receipts
and disbursements for the 2000-01 and 2001-02 fiscal years as a part of the
1999-2000 Executive Budget process, as required by law. The revised expectations
for years 2000-01 and 2001-02 will reflect the cumulative impact of tax
reductions and spending commitments enacted over the last several years as well
as new 1999-2000 Executive Budget recommendations. The School Tax Relief Program
("STAR") program, which dedicates a portion of personal income tax receipts to
fund school tax reductions, has a significant impact on General Fund receipts.
STAR is projected to reduce personal income tax revenues available to the
General Fund by an estimated $1.3 billion in 2000-01. Measured from the 1998-99
base, scheduled reductions to estate and gift, sales and other taxes, reflecting
tax cuts enacted in 1997-98 and 1998-99, will lower General Fund taxes and fees
by an estimated $1.8 billion in 2000-01. Disbursement projections for the
outyears currently assume additional outlays for school aid, Medicaid, welfare
reform, mental health community reinvestment, and other multi-year spending
commitments in law.

            The State's current fiscal year began on April 1, 1998 and ends on
March 31, 1999 and is referred to herein as the State's 1998-99 fiscal year. The
Legislature adopted the debt service component of the State budget for the
1998-99 fiscal year on March 30, 1998 and the 


                                      -26-
<PAGE>
 
remainder of the budget on April 18, 1998. In the period prior to adoption of
the budget for the current fiscal year, the Legislature also enacted
appropriations to permit the State to continue its operations and provide for
other purposes.

            The State's enacted budget includes several new multi-year tax
reduction initiatives, including acceleration of State-funded property and local
income tax relief for senior citizens under the STAR, expansion of the child
care income-tax credit for middle-income families, a phased-in reduction of the
general business tax, and reduction of several other taxes and fees, including
an accelerated phase-out of assessments on medical providers. The enacted budget
also provides for significant increases in spending for public schools, special
education programs, and for the State and City university systems. It also
allocates $50 million for a new Debt Reduction Reserve Fund ("DRRF") that may
eventually be used to pay debt service costs on or to prepay outstanding
State-supported bonds.

            The 1998-99 State Financial Plan projects a closing balance in the
General Fund of $1.42 billion that is comprised of a reserve of $761 million
available for future needs, a balance of $400 million in the Tax Stabilization
Reserve Fund ("TSRF"), a balance of $158 million in the Community Projects Fund
("CPF"), and a balance of $100 million in the Contingency Reserve Fund ("CRF").
The TSRF can be used in the event of an unanticipated General Fund cash
operating deficit, as provided under the State Constitution and State Finance
Law. The CPF is used to finance various legislative and executive initiatives.
The CRF provides resources to help finance any extraordinary litigation costs
during the fiscal year.

            The forecast of General Fund receipts in 1998-99 incorporates
several Executive Budget tax proposals that, if enacted, would further reduce
receipts otherwise available to the General Fund by approximately $700 million
during 1998-99. The Executive Budget proposes accelerating school tax relief for
senior citizens under STAR, which is projected to reduce General Fund receipts
by $537 million in 1998-99. The proposed reduction supplements STAR tax
reductions already scheduled in law, which are projected at $187 million in
1998-99. The Budget also proposes several new tax-cut initiatives and other
funding changes that are projected to further reduce receipts available to the
General Fund by over $200 million. These initiatives include reducing the fee to
register passenger motor vehicles and earmarking a larger portion of such fees
to dedicated funds and other purposes; extending the number of weeks in which
certain clothing purchases are exempt from sales taxes; more fully conforming
State law to reflect recent Federal changes in estate taxes; continuing lower
pari-mutuel tax rates; and accelerating scheduled property tax relief for
farmers from 1999 to 1998. In addition to the specific tax and fee reductions
discussed above, the Executive Budget also proposes establishing a reserve of
$100 million to permit the acceleration into 1998-99 of other tax reductions
that are otherwise scheduled in law for implementation in future fiscal years.

            The DOB estimates that the 1998-99 Financial Plan includes
approximately $64 million in non-recurring resources, comprising less than
two-tenths of one percent of General Fund disbursements. The non-recurring
resources projected for use in 1998-99 consist of $27 million in retroactive
federal welfare reimbursements for family assistance recipients with HIV/AIDS,
$25 million in receipts from the Housing Finance Agency that were originally


                                      -27-
<PAGE>
 
anticipated in 1997-98, and $10 million in other measures, including $5 million
in asset sales. The DOB projects that the 1999-2000 Financial Plan contains only
$33 million in non-recurring resources, or less than one-tenth of one percent of
General Fund disbursements. In 1999-2000, the largest one-time resources consist
of a $15 million loan repayment from the Long Island Power Authority and $8
million from the anticipated sale of State property at 270 Broadway in New York
City. The remaining amounts include various routine transfers to the General
Fund.

            Disbursements from Capital Projects funds in 1998-99 are estimated
at $4.82 billion, or $1.07 billion higher than 1997-98. The proposed spending
plan includes: $2.51 billion in disbursements for transportation purposes,
including the State and local highway and bridge program; $815 million for
environmental activities; $379 million for correctional services; $228 million
for the State University of New York ("SUNY") and the City University of New
York ("CUNY"); $290 million for mental hygiene projects; and $375 million for
CEFAP. Approximately 28 percent of capital projects are proposed to be financed
by "pay-as-you-go" resources. State-supported bond issuances finance 46 percent
of capital projects, with federal grants financing the remaining 26 percent.
Disbursements from Capital Projects funds in 1999-2000 are estimated at $4.41
billion, or $145 million higher than 1998-99. The proposed spending plan
includes: $2.61 billion in disbursements for transportation purposes, including
State and local highway and bridge programs; $709 million for environmental
activities; $348 million for correctional services; $272 million for SUNY and
CUNY; and $271 million for mental hygiene projects.

            The 1999-2000 Financial Plan projects General Fund disbursements and
transfers to other funds of $37.10 billion, an increase of $482 million over
projected spending for the current year. Grants to local governments constitute
approximately 67 percent of all General Fund spending, and include payments to
local governments, non-profit providers and individuals. Disbursements in this
category are projected to decrease $87 million (0.4 percent) to $24.81 billion
in 1999-2000, in part due to a $175 million decline in proposed spending for
legislative initiatives.

            The State is projected to close the 1999-2000 fiscal year with a
General Fund balance of $2.36 billion. The balance is comprised in $1.79 billion
that the Governor is proposing to set aside as a tax reduction reserve, $473
million in the Tax Stabilization Reserve Fund and $100 million in the
Contingency Reserve Fund. The entire $226 million balance in the Community
Projects Fund is expected to be used in 1999-2000, with $80 million spent to pay
for existing projects and the remaining balance of $146 million, against which
there are currently no appropriations as a result of the Governor's 1998 vetoes,
used to fund other expenditures in 1999-2000.

                  The State currently projects spending to grow by $1.09 billion
(2.9 percent) in 2000-01 and an additional $1.8 billion (4.7 percent) in
2001-02. General Fund spending increases at a higher rate in 2001-02 than in
2000-01, driven primarily by higher growth rates for Medicaid, welfare, Children
and Families Services, and Mental Retardation, as well as the loss of federal
money that offsets General Funds spending.

                  Over the long-term, uncertainties with regard to economy
present the largest potential risk to future budget balance in New York State.
For example, a downturn in the financial markets or the wider economy is
possible, a risk that is heightened by the lengthy expansion currently underway.
The securities industry is more important to the New York economy that the
national economy, potentially amplifying the impact of an economic downturn. A
large change in stock market performance during the forecast horizon could
result in wage and unemployment levels that are significantly different from
those embodied in the forecast. Merging and downsizing by firms, as a
consequence of deregulation or continued foreign competition, may also have more
significant adverse effects on employment than expected. Finally, a "forecast
error" of one percentage point in the estimated growth of receipts could
cumulatively raise or lower results by over $1 billion by 2002.

            Many complex political, social and economic forces influence the
State's economy and finances, which may in turn affect the State's Financial
Plan. These forces may affect the State unpredictably from fiscal year to fiscal
year and are influenced by governments, institutions, and organizations that are
not subject to the State's control. The State Financial Plan is also necessarily
based upon forecasts of national and State economic activity. Economic forecasts
have frequently failed to predict accurately the timing and magnitude of changes
in the national and the State economies. The DOB believes that its projections
of receipts and disbursements relating to the current State Financial Plan, and
the assumptions on which they are based, are reasonable. The projections assume
no changes in federal tax law, which could substantially alter the current
receipts forecast. In addition, these projections do not include funding for new
collective bargaining agreements after the current contracts expire on April 1,
1999. Actual results, however, could differ materially and adversely from their
projections, and those projections may be changed materially and adversely from
time to time.

            In the past, the State has taken management actions and made use of
internal sources to address potential State financial plan shortfalls, and the
DOB believes it could take similar actions should variances occur in its
projections for the current fiscal year.

Recent Financial Results. The General Fund is the principal operating fund of
the State and is used to account for all financial transactions, except those
required to be accounted for in another fund. It is the State's largest fund and
receives almost all State taxes and other resources not dedicated to particular
purposes.

            On March 31, 1998, the State recorded, on a GAAP-basis, its
first-ever, accumulated positive balance in its General Fund. This "accumulated
surplus" was $567 million. The improvement in the State's GAAP position is
attributable, in part, to the cash surplus recorded at the end of the State's
1997-98 fiscal year. Much of that surplus is reserved for future requirements,
but a portion is being used to meet spending needs in 1998-99. Thus, the State
expects some deterioration in its GAAP position, but expects to maintain a
positive GAAP balance through the end of the current fiscal year.

            The State completed its 1997-98 fiscal year with a combined
Governmental Funds operating surplus of $1.80 billion, which included an
operating surplus in the General Fund of 


                                      -29-
<PAGE>
 
$1.56 billion, in Capital Projects Funds of $232 million and in Special Revenue
Funds of $49 million, offset in part by an operating deficit of $43 million in
Debt Service Funds.

            The GAAP projections indicate that the State will have three
consecutive years of a GAAP accumulated surplus in the General Fund, eliminating
the GAAP deficit of $3.3 billion that existed on March 31, 1995. In 1998-99, the
General Fund GAAP Financial Plan projects total revenues of $36.63 billion,
total expenditures of $36.07 billion, and net other financing uses of $106
million. In 1999-1000, projections reflect total revenues of $36.14 billion,
total expenditures of $36.18 billion and net other financing uses of $466
million. The net impact of the additional 1998-99 cash surplus accounts for most
of the change in projected operating results across the two fiscal years. At the
end of 1999-2000, the accumulated General Fund GAAP surplus is projected to be
$512 million.

            The State now projects a 1998-1999 closing balance of $799 million
in the General Fund, a decrease of $899 million from the Mid-Year Update. The
decline reflects the payment of the $1.04 billion undesignated reserve
identified in October plus additional surplus monies projected in the January
Update into the tax refund reserve. The projected closing balance of $799
million in the 1998-1999 General Fund is comprised of $473 million in the Tax
Stabilization Reserve Fund, following a new $73 million deposit in 1998-99; $100
million in the Contingency Reserve Fund, following a planned $32 million
deposit; and the remaining balance of $226 million in the Community Projects
Fund.

Debt Limits and Outstanding Debt. There are a number of methods by which the
State of New York may incur debt. Under the State Constitution, the State may
not, with limited exceptions for emergencies, undertake long-term general
obligation borrowing (i.e., borrowing for more than one year) unless the
borrowing is authorized in a specific amount for a single work or purpose by the
Legislature and approved by the voters. There is no limitation on the amount of
long-term general obligation debt that may be so authorized and subsequently
incurred by the State.

            The State may undertake short-term borrowings without voter approval
(i) in anticipation of the receipt of taxes and revenues, by issuing tax and
revenue anticipation notes, and (ii) in anticipation of the receipt of proceeds
from the sale of duly authorized but unissued general obligation bonds, by
issuing bond anticipation notes. The State may also, pursuant to specific
constitutional authorization, directly guarantee certain obligations of the
State of New York's authorities and public benefit corporations ("Authorities").
Payments of debt service on New York State general obligation and New York
State-guaranteed bonds and notes are legally enforceable obligations of the
State of New York.

            The State employs additional long-term financing mechanisms,
lease-purchase and contractual-obligation financings, which involve obligations
of public authorities or municipalities that are State-supported but are not
general obligations of the State. Under these financing arrangements, certain
public authorities and municipalities have issued obligations to finance the
construction and rehabilitation of facilities or the acquisition and
rehabilitation of equipment, and expect to meet their debt service requirements
through the receipt of rental or 


                                      -30-
<PAGE>
 
other contractual payments made by the State. Although these financing
arrangements involve a contractual agreement by the State to make payments to a
public authority, municipality or other entity, the State's obligation to make
such payments is generally expressly made subject to appropriation by the
Legislature and the actual availability of money to the State for making the
payments. The State has also entered into a contractual-obligation financing
arrangement with the LGAC to restructure the way the State makes certain local
aid payments.

            The proposed 1998-99 through 2003-04 Capital Program and Financing
Plan was released with the Executive Budget on January 27, 1999. The recommended
five-year Capital Program and Financing Plan reflects debt reduction initiatives
that would reduce future State-supported debt issuances by significantly
increasing the share of the Plan financed with pay-as-you-go resources. Compared
to the last year of the July 1998 update to the Plan, outstanding
State-supported debt would be reduced by $4.7 billion (from $41.9 billion to
$37.2 billion).

            As described therein, efforts to reduce debt, unanticipated delays
in the advancement of certain projects and revisions to estimated proceeds needs
will modestly reduce projected borrowings in 1998-99. The State's 1998-99
borrowing plan now projects issuances of $331 million in general obligation
bonds (including $154 million for purposes of redeeming outstanding BANs) and
$154 million in general obligation commercial paper. The State has issued $179
million in Certificates of Participation to finance equipment purchases
(including costs of issuance, reserve funds, and other costs) during the 1998-99
fiscal year. Of this amount, it is anticipated that approximately $83 million
will be used to finance agency equipment acquisitions, and $96 million to
address Statewide technology issues related to Year 2000 compliance.
Approximately $228 million for information technology related to welfare reform,
originally anticipated to be issued during the 1998-99 fiscal year, is now
expected to be delayed until 1999-2000.

            In February 1997, the Job Development Authority ("JDA") issued
approximately $85 million of State-guaranteed bonds to refinance certain of its
outstanding bonds and notes in order to restructure and improve JDA's capital
structure. Due to concerns regarding the economic viability of its programs,
JDA's loan and loan guarantee activities had been suspended since the Governor
took office in 1995. As a result of the structural imbalances in JDA's capital
structure, and defaults in its loan portfolio and loan guarantee program
incurred between 1991 and 1996, JDA would have experienced a debt service cash
flow shortfall had it not completed its recent refinancing. JDA anticipates that
it will transact additional refinancings in 1999, 2000 and 2003 to complete its
long-term plan of finance and further alleviate cash flow imbalances which are
likely to occur in future years. JDA recently resumed its lending activities
under a revised set of lending programs and underwriting guidelines.

            On January 13, 1992, Standard & Poor's Ratings Services ("Standard &
Poor's") reduced its ratings on the State's general obligation bonds from A to
A- and, in addition, reduced its ratings on the State's moral obligation, lease
purchase, guaranteed and contractual obligation debt. On August 28, 1997,
Standard & Poor's revised its ratings on the State's general obligation bonds
from A- to A and revised its ratings on the State's moral obligation, lease
purchase, 


                                      -31-
<PAGE>
 
guaranteed and contractual obligation debt. On March 5, 1999, Standard & Poor's
affirmed its A rating on the State's outstanding bonds.

            On January 6, 1992, Moody's Investors Service, Inc. ("Moody's")
reduced its ratings on outstanding limited-liability State lease purchase and
contractual obligations from A to Baa1. On February 28, 1994, Moody's
reconfirmed its A rating on the State's general obligation long-term
indebtedness. On March 20, 1998, Moody's assigned the highest commercial paper
rating of P-1 to the short-term notes of the State. On March 5, 1999, Moody's
affirmed its A2 rating with a stable outlook to the State's general obligations.

            The State anticipates that its capital programs will be financed, in
part, through borrowings by the State and its public authorities in the 1998-99
fiscal year. Information on the State's five-year Capital Program and Financing
Plan for the 1998-99 through 2002-03 fiscal years, updated to reflect actions
taken in the 1998-99 State budget (the "Plan"), was initially released on July
30, 1998. The projection of State borrowings for the 1998-99 fiscal year is
subject to change as market conditions, interest rates and other factors vary
throughout the fiscal year.

            Borrowings by public authorities pursuant to lease-purchase and
contractual-obligation financings for capital programs of the State are
projected to total approximately $2.93 billion, including costs of issuance,
reserve funds, and other costs, net of anticipated refundings and other
adjustments in 1998-99.

            As a part of the Plan, changes were proposed to the State's
borrowing plan, including: the delay in the issuance of certificates of
participation to finance welfare information systems until 1998-99 to permit a
thorough assessment of needs; and the elimination of issuances for the CEFAP to
reflect the proposed conversion of that bond-financed program to pay-as-you-go
financing.

            New York State has never defaulted on any of its general obligation
indebtedness or its obligations under lease-purchase or contractual-obligation
financing arrangements and has never been called upon to make any direct
payments pursuant to its guarantees.

Litigation. Certain litigation pending against New York State or its officers or
employees could have a substantial or long-term adverse effect on New York State
finances. Among the more significant of these cases are those that involve (1)
the validity of agreements and treaties by which various Indian tribes
transferred title to New York State of certain land in central and upstate New
York; (2) certain aspects of New York State's Medicaid policies, including its
rates, regulations and procedures; (3) action against New York State and New
York City officials alleging inadequate shelter allowances to maintain proper
housing; (4) challenges to regulations promulgated by the Superintendent of
Insurance establishing certain excess medical malpractice premium rates; (5)
challenges to the constitutionality of Public Health Law 2807-d, which imposes a
gross receipts tax from certain patient care services; (6) action seeking
enforcement of certain sales and excise taxes and tobacco products and motor
fuel sold to non-Indian consumers on Indian reservations; (7) a challenge to the
Governor's application of his constitutional line 


                                      -32-
<PAGE>
 
item veto authority; and (8) a challenge to the enactment of the Clean
Water/Clean Air Bond Act of 1996.

            Several actions challenging the constitutionality of legislation
enacted during the 1990 legislative session which changed actuarial funding
methods for determining state and local contributions to state employee
retirement systems have been decided against the State. As a result, the
Comptroller developed a plan to restore the State's retirement systems to prior
funding levels. Such funding is expected to exceed prior levels by $116 million
in fiscal 1996-97, $193 million in fiscal 1997-98, peaking at $241 million in
fiscal 1998-99. Beginning in fiscal 2001-02, State contributions required under
the Comptroller's plan are projected to be less than that required under the
prior funding method. As a result of the United States Supreme Court decision in
the case of State of Delaware v. State of New York, on January 21, 1994, the
State entered into a settlement agreement with various parties. Pursuant to all
agreements executed in connection with the action, the State was required to
make aggregate payments of $351.4 million. Annual payments to the various
parties will continue through the State's 2002-03 fiscal year in amounts which
will not exceed $48.4 million in any fiscal year subsequent to the State's
1994-95 fiscal year. Litigation challenging the constitutionality of the
treatment of certain moneys held in a reserve fund was settled in June 1996 and
certain amounts in a Supplemental Reserve Fund previously credited by the State
against prior State and local pension contributions will be paid in 1998.

            The legal proceedings noted above involve State finances, State
programs and miscellaneous cure rights, tort, real property and contract claims
in which the State is a defendant and the monetary damages sought are
substantial, generally in excess of $100 million. These proceedings could affect
adversely the financial condition of the State in the 1998-99 fiscal year or
thereafter. Adverse developments in these proceedings, other proceedings for
which there are unanticipated, unfavorable and material judgments, or the
initiation of new proceedings could affect the ability of the State to maintain
a balanced financial plan. An adverse decision in any of these proceedings could
exceed the amount of the reserve established in the State's financial plan for
the payment of judgments and, therefore, could affect the ability of the State
to maintain a balanced financial plan.

            Although other litigation is pending against New York State, except
as described herein, no current litigation involves New York State's authority,
as a matter of law, to contract indebtedness, issue its obligations, or pay such
indebtedness when it matures, or affects New York State's power or ability, as a
matter of law, to impose or collect significant amounts of taxes and revenues.

Authorities. The fiscal stability of New York State is related, in part, to the
fiscal stability of its Authorities, which generally have responsibility for
financing, constructing and operating revenue-producing public benefit
facilities. Authorities are not subject to the constitutional restrictions on
the incurrence of debt which apply to the State itself, and may issue bonds and
notes within the amounts of, and as otherwise restricted by, their legislative
authorization. The State's access to the public credit markets could be
impaired, and the market price of its outstanding debt may be materially and
adversely affected, if any of the Authorities were to 


                                      -33-
<PAGE>
 
default on their respective obligations, particularly with respect to debt that
is State-supported or State-related.

            Authorities are generally supported by revenues generated by the
projects financed or operated, such as fares, user fees on bridges, highway
tolls and rentals for dormitory rooms and housing. In recent years, however, New
York State has provided financial assistance through appropriations, in some
cases of a recurring nature, to certain of the Authorities for operating and
other expenses and, in fulfillment of its commitments on moral obligation
indebtedness or otherwise, for debt service. This operating assistance is
expected to continue to be required in future years. In addition, certain
statutory arrangements provide for State local assistance payments otherwise
payable to localities to be made under certain circumstances to certain
Authorities. The State has no obligation to provide additional assistance to
localities whose local assistance payments have been paid to Authorities under
these arrangements. However, in the event that such local assistance payments
are so diverted, the affected localities could seek additional State funds.

New York City and Other Localities. The fiscal health of the State may also be
impacted by the fiscal health of its localities, particularly the City, which
has required and continues to require significant financial assistance from the
State. The City depends on State aid both to enable the City to balance its
budget and to meet its cash requirements. There can be no assurance that there
will not be reductions in State aid to the City from amounts currently projected
or that State budgets will be adopted by the April 1 statutory deadline or that
any such reductions or delays will not have adverse effects on the City's cash
flow or expenditures. In addition, the Federal budget negotiation process could
result in a reduction in or a delay in the receipt of Federal grants which could
have additional adverse effects on the City's cash flow or revenues.

            In 1975, New York City suffered a fiscal crisis that impaired the
borrowing ability of both the City and New York State. In that year the City
lost access to the public credit markets. The City was not able to sell
short-term notes to the public again until 1979. In 1975, Standard & Poor's
suspended its A rating of City bonds. This suspension remained in effect until
March 1981, at which time the City received an investment grade rating of BBB
from Standard & Poor's.

            On July 2, 1985, Standard & Poor's revised its rating of City bonds
upward to BBB+ and on November 19, 1987, to A-. On February 3, 1998 and again on
May 27, 1998, Standard & Poor's assigned a BBB+ rating to the City's general
obligation debt and placed the ratings on CreditWatch with positive
implications. On March 9, 1999, Standard & Poor's assigned it's A- rating to
Series 1999H of New York City general obligation bonds and affirmed the A-
rating on various previously issued New York City bonds.

            Moody's ratings of City bonds were revised in November 1981 from B
(in effect since 1977) to Ba1, in November 1983 to Baa, in December 1985 to
Baa1, in May 1988 to A and again in February 1991 to Baa1. On February 25, 1998,
Moody's upgraded approximately $28 billion of the City's general obligations
from Baa1 to A3. On June 9, 1998, Moody's affirmed its A3 rating to the City's
general obligations and stated that its outlook was stable.


                                      -34-
<PAGE>
 
            On March 8, 1999, Fitch IBCA upgraded New York City's $26 billion
outstanding general obligation bonds from A- to A.

            New York City is heavily dependent on New York State and federal
assistance to cover insufficiencies in its revenues. There can be no assurance
that in the future federal and State assistance will enable the City to make up
its budget deficits. To help alleviate the City's financial difficulties, the
Legislature created the Municipal Assistance Corporation ("MAC") in 1975. Since
its creation, MAC has provided, among other things, financing assistance to the
City by refunding maturing City short-term debt and transferring to the City
funds received from sales of MAC bonds and notes. MAC is authorized to issue
bonds and notes payable from certain stock transfer tax revenues, from the
City's portion of the State sales tax derived in the City and, subject to
certain prior claims, from State per capita aid otherwise payable by the State
to the City. Failure by the State to continue the imposition of such taxes, the
reduction of the rate of such taxes to rates less than those in effect on July
2, 1975, failure by the State to pay such aid revenues and the reduction of such
aid revenues below a specified level are included among the events of default in
the resolutions authorizing MAC's long-term debt. The occurrence of an event of
default may result in the acceleration of the maturity of all or a portion of
MAC's debt. MAC bonds and notes constitute general obligations of MAC and do not
constitute an enforceable obligation or debt of either the State or the City.

            Since 1975, the City's financial condition has been subject to
oversight and review by the New York State Financial Control Board (the "Control
Board") and since 1978 the City's financial statements have been audited by
independent accounting firms. To be eligible for guarantees and assistance, the
City is required during a "control period" to submit annually for Control Board
approval, and when a control period is not in effect for Control Board review, a
financial plan for the next four fiscal years covering the City and certain
agencies showing balanced budgets determined in accordance with GAAP. New York
State also established the Office of the State Deputy Comptroller for New York
City ("OSDC") to assist the Control Board in exercising its powers and
responsibilities. On June 30, 1986, the City satisfied the statutory
requirements for termination of the control period. This means that the Control
Board's powers of approval are suspended, but the Board continues to have
oversight responsibilities.

            On June 10, 1997, the City submitted to the Control Board the
Financial Plan (the "1998-2001 Financial Plan") for the 1998 through 2001 fiscal
years, relating to the City, the Board of Education ("BOE") and CUNY and
reflected the City's expense and capital budgets for the 1998 fiscal year, which
were adopted on June 6, 1997. The 1998-2001 Financial Plan projected revenues
and expenditures for the 1998 fiscal year balanced in accordance with GAAP. The
1998-99 Financial Plan projects General Fund receipts (including transfers from
other funds) of $36.22 billion, an increase of $1.02 billion over the estimated
1997-1998 level. Recurring growth in the State General Fund tax base is
projected to be approximately six percent during 1998-99, after adjusting for
tax law and administrative changes. This growth rate is lower than the rates for
1996-97 or currently estimated for 1997-98, but roughly equivalent to the rate
for 1995-96.


                                      -35-
<PAGE>
 
            The 1998-99 forecast for user taxes and fees also reflects the
impact of scheduled tax reductions that will lower receipts by $38 million, as
well as the impact of two Executive Budget proposals that are projected to lower
receipts by an additional $79 million. The first proposal would divert $30
million in motor vehicle registration fees from the General Fund to the
Dedicated Highway and Bridge Trust Fund; the second would reduce fees for motor
vehicle registrations, which would further lower receipts by $49 million. The
underlying growth of receipts in this category is projected at 4 percent, after
adjusting for these scheduled and recommended changes.

            In comparison to the current fiscal year, business tax receipts are
projected to decline slightly in 1998-99, falling from $4.98 million to $4.96
billion. The decline in this category is largely attributable to scheduled tax
reductions. In total, collections for corporation and utility taxes and the
petroleum business tax are projected to fall by $107 million from 1997-98. The
decline in receipts in these categories is partially offset by growth in the
corporation franchise, insurance and bank taxes, which are projected to grow by
$88 million over the current fiscal year.

            The Financial Plan is projected to show a GAAP-basis surplus of $131
million for 1997-98 and a GAAP-basis deficit of $1.3 billion for 1998-99 in the
General Fund, primarily as a result of the use of the 1997-98 cash surplus. In
1998-99, the General Fund GAAP Financial Plan shows total revenues of $34.68
billion, total expenditures of $35.94 billion, and net other financing sources
and uses of $42 million.

            Although the City has consistently maintained balanced budgets and
is projected to achieve balanced operating results for the 1999 fiscal year,
there can be no assurance that the gap-closing actions proposed in the 1998-2001
Financial Plan can be successfully implemented or that the City will maintain a
balanced budget in future years without additional State aid, revenue increases
or expenditure reductions. Additional tax increases and reductions in essential
City services could adversely affect the City's economic base.

            The projections set forth in the 1998-2001 Financial Plan were based
on various assumptions and contingencies which are uncertain and which may not
materialize. Changes in major assumptions could significantly affect the City's
ability to balance its budget as required by State law and to meet its annual
cash flow and financing requirements. Such assumptions and contingencies include
the condition of the regional and local economies, the impact on real estate tax
revenues of the real estate market, wage increases for City employees consistent
with those assumed in the 1998-2001 Financial Plan, employment growth, the
ability to implement proposed reductions in City personnel and other cost
reduction initiatives, the ability of the Health and Hospitals Corporation and
the BOE to take actions to offset reduced revenues, the ability to complete
revenue generating transactions, provision of State and Federal aid and mandate
relief and the impact on City revenues and expenditures of Federal and State
welfare reform and any future legislation affecting Medicare or other
entitlements.

            Implementation of the 1998-2001 Financial Plan is also dependent
upon the City's ability to market its securities successfully. The City's
financing program for fiscal years 1998 


                                      -36-
<PAGE>
 
through 2001 contemplates the issuance of $5.7 billion of general obligation
bonds and $5.7 billion of bonds to be issued by the proposed New York City
Transitional Finance Authority (the "Finance Authority") to finance City capital
projects. The Finance Authority, was created as part of the City's effort to
assist in keeping the City's indebtedness within the forecast level of the
constitutional restrictions on the amount of debt the City is authorized to
incur. Despite this additional financing mechanism, the City currently projects
that, if no further action is taken, it will reach its debt limit in City fiscal
year 1999-2000. Indebtedness subject to the constitutional debt limit includes
liability on capital contracts that are expected to be funded with general
obligation bonds, as well as general obligation bonds. On June 2, 1997, an
action was commenced seeking a declaratory judgment declaring the legislation
establishing the Transitional Finance Authority to be unconstitutional. If such
legislation were voided, projected contracts for the City capital projects would
exceed the City's debt limit during fiscal year 1997-98. Future developments
concerning the City or entities issuing debt for the benefit of the City, and
public discussion of such developments, as well as prevailing market conditions
and securities credit ratings, may affect the ability or cost to sell securities
issued by the City or such entities and may also affect the market for their
outstanding securities.

            The City Comptroller and other agencies and public officials have
issued reports and made public statements which, among other things, state that
projected revenues and expenditures may be different from those forecast in the
City's financial plans. It is reasonable to expect that such reports and
statements will continue to be issued and to engender public comment.

            The City since 1981 has fully satisfied its seasonal financing needs
in the public credit markets, repaying all short-term obligations within their
fiscal year of issuance. Although the City's 1998 fiscal year financial plan
projected $2.4 billion of seasonal financing, the City expected to undertake
only approximately $1.4 billion of seasonal financing. The City issued $2.4
billion of short-term obligations in fiscal year 1997. Seasonal financing
requirements for the 1996 fiscal year increased to $2.4 billion from $2.2
billion and $1.75 billion in the 1995 and 1994 fiscal years, respectively.
Seasonal financing requirements were $1.4 billion in the 1993 fiscal year. The
delay in the adoption of the State's budget in certain past fiscal years has
required the City to issue short-term notes in amounts exceeding those expected
early in such fiscal years.

            Certain localities, in addition to the City, have experienced
financial problems and have requested and received additional New York State
assistance during the last several State fiscal years. The potential impact on
the State of any future requests by localities for additional assistance is not
included in the State's projections of its receipts and disbursements for the
1997-98 fiscal year.

            Fiscal difficulties experienced by the City of Yonkers ("Yonkers")
resulted in the re-establishment of the Financial Control Board for the City of
Yonkers (the "Yonkers Board") by New York State in 1984. The Yonkers Board is
charged with oversight of the fiscal affairs of Yonkers. Future actions taken by
the State to assist Yonkers could result in increased State expenditures for
extraordinary local assistance.


                                      -37-
<PAGE>
 
            On June 30, 1998, the City of Yonkers satisfied the statutory
conditions for ending the supervision of its finances by a State-ordered control
board. Pursuant to State law, the control board's powers over City finances
lapsed six months after the satisfaction of these conditions, on December 31,
1998.

            Beginning in 1990, the City of Troy experienced a series of
budgetary deficits that resulted in the establishment of a Supervisory Board for
the City of Troy in 1994. The Supervisory Board's powers were increased in 1995,
when Troy MAC was created to help Troy avoid default on certain obligations. The
legislation creating Troy MAC prohibits the city of Troy from seeking federal
bankruptcy protection while Troy MAC bonds are outstanding. Troy MAC has issued
bonds to effect a restructuring of the City of Troy's obligations.

            The 1998-99 budget includes $29.4 million in unrestricted aid
targeted to 57 municipalities across the State. Other assistance for
municipalities with special needs totals more than $25.6 million. Twelve upstate
cities will receive $24.2 million in one-time assistance from a cash flow
acceleration of State aid.

            Municipalities and school districts have engaged in substantial
short-term and long-term borrowings. State law requires the Comptroller to
review and make recommendations concerning the budgets of those local government
units other than New York City that are authorized by State law to issue debt to
finance deficits during the period that such deficit financing is outstanding.

            From time to time, federal expenditure reductions could reduce, or
in some cases eliminate, federal funding of some local programs and accordingly
might impose substantial increased expenditure requirements on affected
localities. If the State, the City or any of the Authorities were to suffer
serious financial difficulties jeopardizing their respective access to the
public credit markets, the marketability of notes and bonds issued by localities
within the State could be adversely affected. Localities also face anticipated
and potential problems resulting from certain pending litigation, judicial
decisions and long-range economic trends. Long-range potential problems of
declining urban population, increasing expenditures and other economic trends
could adversely affect localities and require increasing the State assistance in
the future.

Year 2000 Compliance. The State is currently addressing Year 2000 ("Y2K") data
processing compliance issues. Since its inception, the computer industry has
used a two-digit date convention to represent the year. In the year 2000, the
date field will contain "00" and, as a result, many computer systems and
equipment may not be able to process dates properly or may fail since they may
not be able to distinguish between the years 1900 and 2000. The Year 2000 issue
not only affects computer programs, but also the hardware, software and networks
they operate on. In addition, any system or equipment that is dependent on an
embedded chip, such as telecommunication equipment and security systems, may
also be adversely affected.

            The Office for Technology is monitoring compliance progress for the
State's mission-critical and high-priority systems and is reporting compliance
progress to the Governor's 


                                      -38-
<PAGE>
 
office on a quarterly basis. As of December 1998, the State had completed 93
percent of overall compliance effort for its mission-critical systems; 18
systems are now Years 2000 compliant and the remaining systems are on schedule
to be compliant by the first quarter of 1999. As of December 1998, the State has
completed 70 percent of overall compliance effort on the high-priority systems;
168 systems are now Year 2000 compliant and the remaining systems are on
schedule to be compliant by the second quarter of 1999. Compliance testing is
expected to be completed by the end of calendar 1999.

            While New York State is taking what is believes to be appropriate
action to address Year 2000 compliance, there can be no guarantee that all of
the State's systems and equipment will be Year 2000 compliant and that there
will not be an adverse impact upon State operations or finances as a result.
Since Year 2000 compliance by outside parties is beyond the State's control to
remediate, the failure of outside parties to achieve Year 2000 compliance could
have an adverse impact on State operations or finances as well.

Standby Commitments

      In order to enhance the liquidity, stability or quality of municipal
obligations, the ILA Prime Obligations Portfolio, ILA Money Market Portfolio,
ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California Portfolio, ILA
Tax-Exempt New York Portfolio, FS Prime Obligations Fund, FS Premium Fund, FS
Money Market Fund, FS Tax-Free Fund and FS Municipal Fund each may acquire the
right to sell a security to another party at a guaranteed price and date. Such a
right to resell may be referred to as a put, demand feature or "standby
commitment," depending on its characteristics. The aggregate price which a
Series pays for securities with standby commitments may be higher than the price
which otherwise would be paid for the securities. Standby commitments may not be
available or may not be available on satisfactory terms.

      Standby commitments may involve letters of credit issued by domestic or
foreign banks supporting the other party's ability to purchase the security from
the Series. The right to sell may be exercisable on demand or at specified
intervals, and may form part of a security or be acquired separately by the
Series.

      Management of the Trust understands that the Internal Revenue Service has
issued a favorable revenue ruling to the effect that, under specified
circumstances, a registered investment company will be the owner of tax-exempt
municipal obligations acquired subject to a put option. Institutional Tax-Exempt
Assets, the predecessor company of which ILA Tax-Exempt Diversified Portfolio
and ILA Tax-Exempt California Portfolio were series, has received a ruling from
the Internal Revenue Service to the effect that it is considered the owner of
the municipal obligations subject to standby commitments so that the interest on
such instruments will be tax-exempt income to it. (Such rulings do not, however,
serve as precedent for other taxpayers, are applicable only to the taxpayer
requesting the ruling and have, on occasion, been reversed by the Internal
Revenue Service.) The Internal Revenue Service has subsequently announced that
it will not ordinarily issue advance ruling letters as to the identity of the
true owner of property in cases involving the sale of securities or
participation interests therein if the purchaser has the 


                                      -39-
<PAGE>
 
right to cause the security, or the participation interest therein, to be
purchased by either the seller or a third party. Each of the ILA Tax-Exempt
Diversified Portfolio, ILA Tax-Exempt California Portfolio, ILA Tax-Exempt New
York Portfolio, FS Tax-Free Fund and FS Municipal Fund intends to take the
position that it is the owner of any municipal obligations acquired subject to a
standby commitment or acquired or held with certain other types of put rights
and that its distributions of tax-exempt interest earned with respect to such
municipal obligations will be tax-exempt for its unitholders. There is no
assurance that standby commitments will be available to a Series nor has any
Series assumed that such commitments will continue to be available under all
market conditions.

Borrowings and Reverse Repurchase Agreements. A Series can borrow money from
banks and enter into reverse repurchase agreements with banks and other
financial institutions in amounts not exceeding one-third of its total assets.
Reverse repurchase agreements involve the sale of securities held by a series
subject to the Series' agreements to repurchase them at a mutually agreed upon
date and price (including interest). These transactions may be entered into as a
temporary measure for emergency purposes or to meet redemption requests.
Borrowings and reverse repurchase agreements involve leveraging. If the
securities held by a Series decline in value while these transactions are
outstanding, the Series' market value will decline in value by proportionately
more than the decline in value of the securities. In addition, reverse
repurchase agreements involve the risk that the interest income earned by a
Series (from the investment of the proceeds) will be less than the interest
expense of the transaction, that the market value of the securities sold by a
Series will decline below the price of the Series is obligated to pay to
repurchase the securities, and that the securities may not be returned to the
Series.

Non-Diversified Status

      Since the ILA Tax-Exempt California Portfolio and ILA Tax-Exempt New York
Portfolio are "non-diversified" under the Act, each is subject only to
applicable tax requirements. Under federal tax laws, the ILA Tax-Exempt
California Portfolio and ILA Tax-Exempt New York Portfolio may, with respect to
50% of their total assets, invest up to 25% of their total assets in the
securities of any issuer (except that this limitation does not apply to U.S.
Government Securities). With respect to the remaining 50% of each Series' total
assets, (1) the Series may not invest more than 5% of its total assets in the
securities of any one issuer (other than the U.S. Government), and (2) the
Series may acquire more than 10% of the outstanding voting securities of any one
issuer. These tests apply at the end of each quarter of its taxable year and are
subject to certain conditions and limitations under the Internal Revenue Code of
1986, as amended (the "Code").

                             INVESTMENT LIMITATIONS

      The following investment restrictions have been adopted by the Trust as
fundamental policies that cannot be changed with respect to any Series without
the approval of the majority of outstanding voting securities of that Series.
The investment objective of each Series and all other 


                                      -40-
<PAGE>
 
investment policies or practices of the Series, except as stated in this
paragraph, are considered by the Trust not to be fundamental and accordingly may
be changed without unitholder approval. As a matter of fundamental policy, at
least 80% of the net assets of each of the ILA Tax-Exempt Diversified Portfolio,
ILA Tax-Exempt California Portfolio, ILA Tax-Exempt New York Portfolio, FS
Tax-Free Fund and FS Municipal Fund will ordinarily be invested in municipal
obligations, the interest from which is in the opinion of bond counsel, if any,
excluded from gross income for federal income tax purposes. In addition, as a
matter of fundamental policy, at least 65% of the total assets of each of the
ILA Tax-Exempt California Portfolio and ILA Tax- Exempt New York Portfolio will
be invested in California and New York municipal obligations, respectively,
except in extraordinary circumstances. Each of these five Series may temporarily
invest in taxable money market instruments or, in the case of the ILA Tax-Exempt
California and ILA Tax-Exempt New York Portfolio, in municipal obligations that
are not California or New York municipal obligations, respectively, when
acceptable California and New York obligations are not available or when the
Investment Adviser believes that the market conditions dictate a defensive
posture.

      As defined in the Act and the rules thereunder and as used in the
Prospectus and this Statement of Additional Information, "a majority of the
outstanding voting securities" of a Series means the lesser of (1) 67% of the
units of that Series present at a meeting if the holders of more than 50% of the
outstanding units of that Series are present in person or by proxy, or (2) more
than 50% of the outstanding units of that Series. Investment restrictions that
involve a maximum percentage of securities or assets shall not be considered to
be violated unless an excess over the percentage occurs immediately after, and
is caused by, an acquisition or encumbrance of securities or assets of, or
borrowings by or on behalf of, a Series, with the exception of borrowings
permitted by Investment Restriction (3).

      Accordingly, the Trust may not, on behalf of any Series (except for FS
Government Fund):

            (1) Make any investment inconsistent with the Series' classification
      as a diversified company under the Act. This restriction does not,
      however, apply to any Series classified as a non-diversified company under
      the Act.

            (2) Purchase securities if such purchase would cause more than 25%
      in the aggregate of the market value of the total assets of a Series to be
      invested in the securities of one or more issuers having their principal
      business activities in the same industry, provided that there is no
      limitation with respect to, and each Series (other than the FS Money
      Market Fund and FS Premium Fund) reserves freedom of action, when
      otherwise consistent with its investment policies, to concentrate its
      investments in obligations issued or guaranteed by the U.S. Government,
      its agencies or instrumentalities, obligations (other than commercial
      paper) issued or guaranteed by U.S. banks and U.S. branches of U.S. or
      foreign banks and repurchase agreements and securities loans
      collateralized by such U.S. Government obligations or such bank
      obligations. Each of FS Money Market Fund and FS Premium Fund may
      concentrate its investments in obligations issued or guaranteed by the
      U.S. Government, its agencies and 


                                      -41-
<PAGE>
 
      instrumentalities and repurchase agreements and securities loans
      collateralized by such obligations and will invest more than 25% of its
      total assets in obligations issued or guaranteed by banks (whether foreign
      or domestic) and repurchase agreements and securities loans collateralized
      by such obligations. However, if adverse economic conditions prevail in
      the banking industry, each of FS Money Market Fund and FS Premium Fund
      may, for defensive purposes, temporarily invest less than 25% of the value
      of its total assets in such obligations. Notwithstanding the foregoing,
      the ILA Money Market Portfolio will invest more than 25% of the value of
      its total assets in bank obligations (whether foreign or domestic) except
      that if adverse economic conditions prevail in the banking industry, the
      ILA Money Market Portfolio may, for defensive purposes, temporarily invest
      less than 25% of its total assets in bank obligations. For the purposes of
      this restriction, state and municipal governments and their agencies,
      authorities and instrumentalities are not deemed to be industries;
      telephone companies are considered to be a separate industry from water,
      gas or electric utilities; personal credit finance companies and business
      credit finance companies are deemed to be separate industries; and wholly
      owned finance companies are considered to be in the industry of their
      parents if their activities are primarily related to financing the
      activities of their parents.

            (3) Borrow money, except that (a) the Series may borrow from banks
      (as defined in the Act) or through reverse repurchase agreements in
      amounts up to 33 1/3% of its total assets (including the amount borrowed),
      (b) the Series may, to the extent permitted by applicable law, borrow up
      to an additional 5% of its total assets for temporary purposes, (c) the
      Series may obtain such short-term credit as may be necessary for the
      clearance of purchases and sales of portfolio securities and (d) the
      Series may purchase securities on margin to the extent permitted by
      applicable law.

            (4) Make loans, except (a) through the purchase of debt obligations
      in accordance with each Series' investment objective and policies, (b)
      through repurchase agreements with banks, brokers, dealers and other
      financial institutions, (c) with respect to the Financial Square Funds,
      loans of securities as permitted by applicable law, and (d) with respect
      to the ILA Portfolios, loans of securities.

            (5) Underwrite securities issued by others, except to the extent
      that the sale of portfolio securities by the Series may be deemed to be an
      underwriting.

            (6) Purchase, hold or deal in real estate, although the Series may
      purchase and sell securities that are secured by real estate or interests
      therein, securities of real estate investment trusts and mortgage-related
      securities and may hold and sell real estate acquired by the Series as a
      result of the ownership of securities.

            (7) Invest in commodities or commodity contracts, except that the
      Series may invest in currency and financial instruments and contracts that
      are commodities or commodity contracts.

            (8) Issue senior securities to the extent such issuance would
      violate applicable law.

      FS Government Fund may not:

            (1) With respect to 75% of its total assets taken at market value,
      invest more than 5% of the value of the total assets of that Series in the
      securities of any one issuer, except U.S. Government securities and
      repurchase agreements collateralized by U.S. Government securities. This
      restriction does not, however, apply to any Series classified as a
      non-diversified company under the Act.

            (2) With respect to 75% of its total assets taken at market value,
      purchase the securities of any one issuer if, as a result of such
      purchase, that Series would hold more than 10% of the outstanding voting
      securities of that issuer. This restriction does not, however, apply to
      any Series classified as a non-diversified company under the Act.

            (3) Borrow money, except from banks on a temporary basis for
      extraordinary or emergency purposes, provided that a Series is required to
      maintain asset coverage of 300% for all borrowings and that no purchases
      of securities will be made if such borrowings exceed 5% of the value of
      the Series' assets. This restriction does not apply to cash collateral
      received as a result of portfolio securities lending.

            (4) Mortgage, pledge or hypothecate its assets except to secure
      permitted borrowings.

            (5) Act as underwriter of the securities issued by others, except to
      the extent that the purchase of securities in accordance with a Series'
      investment objective and policies directly from the issuer thereof and the
      later disposition thereof may be deemed to be underwriting.

            (6) Purchase securities if such purchase would cause more than 25%
      in the aggregate of the market value of the total assets of a Series to be
      invested in the securities of one or more issuers having their principal
      business activities in the same industry, provided that there is no
      limitation with respect to, and the Series reserves freedom of action,
      when otherwise consistent with its investment policies, to concentrate its
      investments in U.S. Government securities, obligations (other than
      commercial paper) issued or guaranteed by U.S. banks, and U.S. branches of
      foreign banks and repurchase agreements and securities loans
      collateralized by U.S. Government securities or such bank obligations.
      (For the purposes of this restriction, state and municipal governments and
      their agencies and authorities are not deemed to be industries, and
      telephone companies are considered to be a separate industry from water,
      gas or electric utilities, personal credit finance companies and business
      credit finance companies are deemed to be separate industries and
      wholly-owned finance companies are considered to be in the industry of
      their parents if their activities are primarily related to financing the
      activities of their parents. Such concentration may be effected when the
      Investment Adviser 


                                      -43-
<PAGE>
 
      determines that risk adjusted returns in such industries are considered
      favorable relative to other industries.)

            (7) Issue senior securities, except as appropriate to evidence
      indebtedness that a Series is permitted to incur and except for shares of
      existing or additional series of the Trust.

            (8) Purchase or sell real estate (excluding securities secured by
      real estate or interests therein), interests in oil, gas or mineral
      leases, commodities or commodities contracts. The Trust reserves the
      freedom to hold and to sell real estate acquired for any Series as a
      result of the ownership of securities.

            (9) Make loans to other persons, except loans of portfolio
      securities and except to the extent that the purchase of debt obligations
      and entry into repurchase agreements in accordance with such Series'
      investment objective and policies may be deemed to be loans.

            (10) Purchase securities on margin (except for delayed delivery or
      when-issued transactions or such short-term credits as are necessary for
      the clearance of transactions), make short sales of securities, maintain a
      short position, or invest in or write puts, calls or combinations thereof
      (except that a Series may acquire puts in connection with the acquisition
      of a debt instrument).

            (11) Invest in other companies for the purpose of exercising control
      or management.

      Each Series may, notwithstanding any other fundamental investment
restriction or policy, invest some or all of its assets in a single open-end
investment company or series thereof with substantially the same investment
objectives, restrictions and policies as the Series.

      As money market funds, the Series must also comply, as a non-fundamental
policy, with Rule 2a-7 under the Act. While a detailed and technical Rule, Rule
2a-7 has three basic requirements: portfolio maturity, portfolio quality and
portfolio diversification. Portfolio maturity. Rule 2a-7 requires that the
maximum maturity (as determined in accordance with Rule 2a-7) of any security in
a Series' portfolio may not exceed 397 days and a Portfolio's average portfolio
maturity may not exceed 90 days. Portfolio quality. A money market fund may only
invest in First Tier and Second Tier securities (as defined in the Rule and the
Prospectus). Each Series, other than the ILA Tax-Exempt Diversified Portfolio,
ILA Tax-Exempt California Portfolio, ILA Tax-Exempt New York Portfolio, FST
Tax-Free Fund and FS Municipal Fund (the "Tax-Exempt Series"), as a matter of
non-fundamental policy, only invests in First Tier securities. Portfolio
diversification. The ILA Prime Obligations, ILA Government, ILA Treasury
Obligations, ILA Money Market, ILA Federal, ILA Treasury Instruments and ILA
Tax-Exempt Diversified Portfolios, FS Prime Obligations, FS Premium, FS
Government, FS Treasury Obligations, FS Money Market, FS Federal, FS Treasury
Instruments, FS Tax-Free and FS Municipal Funds may not invest more than 5% of
their total assets in the securities of any one 


                                      -44-
<PAGE>
 
issuer (except U.S. Government Securities, repurchase agreements collateralized
by such securities and certain securities subject to a guarantee or
unconditional demand feature). Each of such Series may, however, invest up to
25% of its total assets in the First Tier Securities of a single issuer for a
period of up to three business days after the purchase thereof. ILA Tax-Exempt
New York and ILA Tax-Exempt California Portfolios, with respect to 75% of their
respective total assets, may not invest more than 5% of their total assets in
the securities of any one issuer (except U.S. Government Securities, repurchase
agreements collateralized by such securities and certain securities subject to a
guarantee or unconditional demand feature); provided that such Series may not
invest more than 5% of their respective total assets in the securities of a
single issuer unless the securities are First Tier securities. Subject to
certain exceptions, immediately after the acquisition of any demand features or
guarantees (i.e., generally, the right to sell the security at a price equal to
its approximate amortized cost (for a demand feature) or principal amount (for a
guarantee) plus accrued interest), with respect to 75% of the assets of a
Series, no more than 10% of the Series' total assets may be invested in
securities issued by or subject to demand features or guarantees issued by the
same issuer. In the case of the Tax-Exempt Series (which are the only Series
that are permitted to invest in Second Tier securities), subject to certain
exceptions immediately after the acquisition of a demand feature or guarantee
that is a Second Tier security, no more than 5% of the Tax-Exempt Series' total
assets may be invested in securities or demand features or guarantees issued by
the institution that issued the demand feature or guarantee. The Tax-Exempt
Series' investment in Second Tier securities that are conduit securities (which,
generally, are municipal securities involving an agreement or arrangement
providing for payment by a person other than the issuer of the municipal
security) that are not U.S. Government Securities or securities with a guarantee
by a non-controlled person, may not exceed 1% of the Series' total assets. Also,
the Tax-Exempt Series' investment in Second Tier conduit securities of all
issuers combined may not exceed 5% of the Series' total assets. Securities which
are rated in the highest short-term rating category by at least two Nationally
Recognized Statistical Rating Organizations ("NRSROs"), or if only one NRSRO has
assigned a rating, by that NRSRO are "First Tier Securities." Securities rated
in the top two short-term rating categories by at least two NRSROs or by the
only NRSRO which has assigned a rating, but which are not First Tier Securities
are "Second Tier Securities." Unrated securities may also be First Tier or
Second Tier securities if they are of comparable quality as determined by the
Investment Adviser. In accordance with certain rules, the rating of demand
feature or guarantee of a security may be deemed to be the rating of the
underlying security. NRSROs include S&P, Moody's, Duff and Phelps, Inc., Fitch
IBCA Inc., and Thomson BankWatch, Inc. For a description of their rating
categories, see Appendix A.

      "Value" for the purposes of all investment restrictions means the value
used in determining a Series' net asset value. "U.S. Government Securities"
shall mean securities issued or guaranteed by the U.S. Government or any of its
agencies or instrumentalities.

      In addition to the fundamental policies mentioned above, the Board of
Trustees of the Trust has adopted the following non-fundamental policies with
respect to the Financial Square Funds which may be changed or amended by action
of the Board of Trustees without approval of shareholders. Accordingly, the
Trust may not, on the behalf of any Series:


                                      -45-
<PAGE>
 
      (a)   Invest in companies for the purpose of exercising control or
            management.

      (b)   Invest more than 10% of a Series' net assets in illiquid investments
            including repurchase agreements with a notice or demand period of
            more than seven days, securities which are not readily marketable
            and restricted securities not eligible for resale pursuant to Rule
            144A under the 1933 Act.

      (c)   Purchase additional securities if the Series' borrowings exceed 5%
            of its net assets.

      (d)   Make short sales of securities, except short sales against the box.

                              TRUSTEES AND OFFICERS

      The Trustees of the Trust are responsible for deciding matters of general
policy and reviewing the actions of the Investment Adviser, distributor and
transfer agent. The officers of the Trust conduct and supervise each Series
daily business operations.

      Information pertaining to the Trustees and officers of the Trust is set

/3/     The Goldman Sachs Funds Complex consists of Goldman Sachs Trust and
        Goldman Sachs Variable Insurance Trust. Goldman Sachs Trust consisted of
        45 mutual funds, including the 17 series, on December 31, 1998. Goldman
        Sachs Variable Insurance Trust consisted of 8 mutual funds on December
        31, 1998.

             THE INVESTMENT ADVISER, DISTRIBUTOR AND TRANSFER AGENT

The Investment Adviser

      GSAM, a separate operating division of Goldman Sachs, acts as the
Investment Adviser to the Series. Under the Management Agreement between Goldman
Sachs on behalf of GSAM and the Trust on behalf of the Series, GSAM, subject to
the supervision of the Board of Trustees of the Trust and in conformity with the
stated policies of each Series, acts as Investment Adviser and directs the
investments of the Series. In addition, GSAM administers the Series' business
affairs and, in connection therewith, furnishes the Trust with office facilities
and (to the extent not provided by the Trust's custodian, transfer agent, or
other organizations) clerical, recordkeeping and bookkeeping services and
maintains the financial and account records required to be maintained by the
Trust. As compensation for these services and for assuming expenses related
thereto, the Trust pays GSAM a fee, computed daily and paid monthly, at an


                                      -54-
<PAGE>
 
annual rate of .35% and .205% of each ILA Portfolio's and Financial Square
Fund's average daily net assets, respectively. GSAM has agreed to reduce or
otherwise limit the operating expenses of the respective Series, excluding
taxes, interest, brokerage and litigation, indemnification and other
extraordinary expenses, on an annualized basis, as described in the Series
Prospectus. The amount of such reductions or limits, if any, are calculated
monthly and are based on the cumulative difference between a Series' estimated
annualized expense ratio and the expense limit for that Series. This amount will
be reduced by any prior payments related to the current fiscal year. GSAM has
also voluntarily agreed to waive a portion of its management fee for the ILA
Money Market Portfolio, ILA Treasury Instruments Portfolio, ILA Federal
Portfolio, ILA Tax-Exempt Diversified Portfolio and ILA Tax-Exempt New York
Portfolio and for each Financial Square Fund during the fiscal year ended
December 31, 1998. Goldman Sachs has agreed to permit the Financial Square Funds
and the ILA Portfolios to use the name "Goldman Sachs" or a derivative thereof
as part of each Financial Square Fund's name for as long as the Management
Agreement is in effect.

      Goldman Sachs has authorized any of its directors, partners, officers and
employees who have been elected or appointed to the position of Trustee or
officer of the Trust to serve in the capacities in which they have been elected
and appointed.

      The Trust, on behalf of each Series, is responsible for all expenses other
than those expressly borne by GSAM under the Series' Management Agreement. The
expenses borne by units of each Series include, without limitation, the fees
payable to GSAM, the fees and expenses under the Trust's distribution,
administration and service plans, the fees and expenses of the Series'
custodian, fees and expenses of the Series' transfer agent, filing fees for the
registration or qualification of units under federal or state securities laws,
expenses of the organization of the Series, taxes (including income and excise
taxes, if any), interest, costs of liability insurance, fidelity bonds,
indemnification or contribution, any costs, expenses or losses arising out of
any liability of, or claim for damages or other relief asserted against, the
Series for violation of any law, legal and auditing and tax fees and expenses
(including the cost of legal and certain accounting services rendered by
employees of Goldman Sachs with respect to the Series), expenses of preparing
and setting in type prospectuses, statements of additional information, proxy
material, reports and notices, the printing and distribution of the same to
unitholders and regulatory authorities, its proportionate share of the
compensation and expenses of its "non-interested" Trustees, and extraordinary
expenses incurred by the Series.

      The Management Agreement entered into on behalf of the ILA Portfolios (the
"ILA Management Agreement") was most recently approved by the Board of Trustees,
including the "non-interested" Trustees, on April 27, 1999 and by the
unitholders of each ILA Portfolio (other than the ILA Treasury Instruments and
ILA Tax-Exempt New York Portfolios) on April 19, 1990 and by the unitholders of
the ILA Treasury Instruments and ILA Tax-Exempt New York Portfolios on June 3,
1991. The ILA Management Agreement will remain in effect until June 30, 2000 and
will continue in effect thereafter only if such continuance is specifically
approved at least annually by a majority of the Trustees or by a vote of a
majority of the outstanding voting securities of the particular ILA Portfolio,
as defined in the Act, and, in either case, by a majority of "non-interested"
Trustees.

      The FS Management Agreement entered into on behalf of the Financial Square
Funds was most recently approved by the Trustees, including the "non-interested"
Trustees, on April 27, 1999. The Financial Square Funds' shareholders approved
the FS Management Agreement on April 21, 1997. The FS Management Agreement will
remain in effect until June 30, 2000 and will continue in effect thereafter only
if such continuance is specifically approved at least annually by a majority of
the Trustees or by a vote of a majority of the outstanding voting securities of
the particular Financial Square Fund (as defined in the Act) and, in either
case, by a majority of "non-interested" Trustees.

      Prior to May 1, 1997, the Financial Square Funds then in operation had
separate investment advisory and administration agreements. Effective May 1,
1997 the services under such agreements were combined in the Management
Agreement (the "FS Management Agreement"). The services required to be performed
for the Financial Square Funds and the combined advisory and administration fees
payable by the Financial Square Funds under the former advisory and
administration agreements are identical to the services and fees under the FS
Management Agreement. For the fiscal years ended December 31, 1998, December 31,
1997 and December 31, 1996 the amounts of the management fee (including both
advisory and administration fees) incurred by each Financial Square Fund (other
than the FS Municipal Fund, which had not yet commenced operations) were as
follows:

      The ILA Management and FS Management Agreements provide that GSAM shall
not be liable to an ILA Portfolio or Financial Square Fund for any error of
judgment by GSAM or for any loss sustained by the ILA Portfolio or Financial
Square Fund except in the case of GSAM's willful misfeasance, bad faith, gross
negligence or reckless disregard of duty. The ILA Management and FS Management
Agreements also provide that they shall terminate automatically if assigned and
that they may be terminated with respect to any particular ILA Portfolio or
Financial Square Fund without penalty by vote of a majority of the Trustees or a
majority of the outstanding voting securities of that ILA Portfolio or Financial
Square Fund on 


                                      -58-

60 days' written notice to GSAM or by GSAM without penalty at any time on 90
days' (60 days with respect to an Financial Square Fund) written notice to the
Trust.

      In managing the Goldman Sachs Money Market Funds, GSAM will draw upon the
Goldman Sachs Credit Department. The Credit Department provides credit risk
management for our portfolios through a team of 108 professionals who contribute
a combination of industry analysis, fund-specific expertise and global capacity
(through their local presence in foreign markets). The credit department
continuously monitors all issuers approved for investment by the money market
funds by monitoring news stories, business developments, financial information
and ratings, as well as occasional discussion with issuer management and rating
agency analysts. The Credit Department receives rating agency reports and rating
change information electronically and via fax as well as reports from Goldman's
Research Department. Specifically with regards to managing the ILA Tax-Exempt
Diversified Portfolio, ILA Tax-Exempt California Portfolio, ILA Tax-Exempt New
York Portfolio, FS Tax-Free Money Market Fund and FS Municipal Money Market
Fund, GSAM will draw upon the extensive research generated by Goldman Sachs'
Municipal Credit Group. The Credit Group's research team continually reviews
current information regarding the issuers of municipal and other tax-exempt
securities, with particular focus on long-term creditworthiness, short-term
liquidity, debt service costs, liability structures, and administrative and
economic characteristics.

The Distributor and Transfer Agent

      Goldman Sachs acts as principal underwriter and distributor of each
Series' units. Units of the Series are offered and sold on a continuous basis by
Goldman Sachs, acting as agent. The Distribution Agreement between Goldman Sachs
and the Trust was most recently approved by the Trustees on April 27, 1999.
Goldman Sachs retained approximately $2,000, $10,530 and $300 of commissions on
redemptions of ILA Class B shares during 1998, 1997 and 1996, respectively.
Goldman Sachs also serves as the Series' transfer agent. Goldman Sachs provides
customary transfer agency services to the Series, including the handling of
unitholder communications, the processing of unitholder transactions, the
maintenance of unitholder account records, payment of dividends and
distributions and related functions. For these services, Goldman Sachs receives
 .04% (on an annualized basis) of the average daily net assets with respect to
each class of each ILA Portfolio. Goldman Sachs currently imposes no fees under
its transfer agency agreement with the Financial Square Funds.

      For the fiscal years ended December 31, 1998, December 31, 1997, and
December 31, 1996 the ILA Portfolios incurred transfer agency fees as follows:

      Goldman Sachs is one of the largest international investment banking firms
in the United States. Founded in 1869, Goldman Sachs is a major investment
banking and brokerage firm providing a broad range of financing and investment
services both in the United States and abroad. The Goldman Sachs Group, L.P.,
which controls the Investment Adviser, announced that it will pursue an initial
public offering of the firm in the late spring or early summer of 1999.
Simultaneously with the offering, the Goldman Sachs Group, L.P. will merge into
The Goldman Sachs Group, Inc. Goldman Sachs became registered as an Investment
Adviser in 1981. As of February 28, 1999, Goldman Sachs, together with its
affiliates, acted as Investment Adviser, administrator or distributor for
approximately $199 billion in total assets.

      Activities of Goldman Sachs and Its Affiliates and Other Accounts Managed
by Goldman Sachs. The involvement of the Investment Adviser and Goldman Sachs
and their affiliates, in the management of, or their interest in, other accounts
and other activities of Goldman Sachs may present conflicts of interest with
respect to the Series or impede their investment activities.

      Goldman Sachs and its affiliates, including, without limitation, the
Investment Adviser and its advisory affiliates have proprietary interests in,
and may manage or advise with respect to, accounts or funds (including separate
accounts and other funds and collective investment vehicles) which have
investment objectives similar to those of the Series and/or which engage in
transactions in the same types of securities, currencies and instruments as the
Series. Goldman Sachs and its affiliates are major participants in the global
currency, equities, swap and fixed-income markets, in each case both on a
proprietary basis and for the accounts of customers. As such, Goldman Sachs and
its affiliates are actively engaged in transactions in the same securities,
currencies, and instruments in which the Series invest. Such activities could
affect the prices and availability of the securities, currencies, and
instruments in which the Series invest, which could have an adverse impact on
each Series' performance. Such transactions, particularly in respect of
proprietary accounts or customer accounts other than those included in the
Investment Adviser's and its advisory affiliates' asset management activities,
will be executed independently of the Series' transactions and thus at prices or
rates that may be more or less favorable. When the Investment Adviser and its
advisory affiliates seek to purchase or sell the same assets for their managed
accounts, including the Series, the assets actually purchased or sold may be
allocated among the accounts on a basis determined in its good faith discretion
to be equitable. In some cases, this system may adversely affect the size or the
price of the assets purchased or sold for the Series.


                                      -60-
<PAGE>
 
      From time to time, the Series' activities may be restricted because of
regulatory restrictions applicable to Goldman Sachs and its affiliates, and/or
their internal policies designed to comply with such restrictions. As a result,
there may be periods, for example, when the Investment Adviser, and/or its
affiliates, will not initiate or recommend certain types of transactions in
certain securities or instruments with respect to which the Investment Adviser
and/or its affiliates are performing services or when position limits have been
reached.

      In connection with their management of the Series, the Investment Adviser
may have access to certain fundamental analysis and proprietary technical models
developed by Goldman Sachs and other affiliates. The Investment Adviser will not
be under any obligation, however, to effect transactions on behalf of the Series
in accordance with such analysis and models. In addition, neither Goldman Sachs
nor any of its affiliates will have any obligation to make available any
information regarding their proprietary activities or strategies, or the
activities or strategies used for other accounts managed by them, for the
benefit of the management of the Series. The proprietary activities or portfolio
strategies of Goldman Sachs and its affiliates or the activities or strategies
used for accounts managed by them or other customer accounts could conflict with
the transactions and strategies employed by the Investment Adviser in managing
the Series.

      The results of each Series' investment activities may differ significantly
from the results achieved by the Investment Adviser and its affiliates for their
proprietary accounts or other accounts (including investment companies or
collective investment vehicles) managed or advised by them. It is possible that
Goldman Sachs and its affiliates and such other accounts will achieve investment
results which are substantially more or less favorable than the results achieved
by a Series. Moreover, it is possible that a Series will sustain losses during
periods in which Goldman Sachs and its affiliates achieve significant profits on
their trading for proprietary or other accounts. The opposite result is also
possible.

      An investment policy committee which may include partners of Goldman Sachs
and its affiliates may develop general policies regarding a Series' activities,
but will not be involved in the day-to-day management of such Series. In such
instances, those individuals may, as a result, obtain information regarding the
Series' proposed investment activities which is not generally available to the
public. In addition, by virtue of their affiliation with Goldman Sachs, any such
member of an investment policy committee will have direct or indirect interests
in the activities of Goldman Sachs and its affiliates in securities, currencies
and investments similar to those in which the Series invests.

      In addition, certain principals and certain of the employees of the
Investment Adviser are also principals or employees of Goldman Sachs or its
affiliated entities. As a result, the performance by these principals and
employees of their obligations to such other entities may be a consideration of
which investors in the Series should be aware.

      The Investment Adviser may enter into transactions and invest in
instruments in which customers of Goldman Sachs serve as the counterparty,
principal or issuer. In such cases, such 


                                      -61-
<PAGE>
 
party's interests in the transaction will be adverse to the interests of the
Series, and such party may have no incentive to assure that the Series obtain
the best possible prices or terms in connection with the transactions. Goldman
Sachs and its affiliates may also create, write or issue derivative instruments
for customers of Goldman Sachs or its affiliates, the underlying securities,
currencies or instruments of which may be those in which the Series invest or
which may be based on the performance of a Series. The Series may, subject to
applicable law, purchase investments which are the subject of an underwriting or
other distribution by Goldman Sachs or its affiliates and may also enter into
transactions with other clients of Goldman Sachs or its affiliates where such
other clients have interests adverse to those of the Series. At times, these
activities may cause departments of Goldman Sachs or its affiliates to give
advice to clients that may cause these clients to take actions adverse to the
interests of the client. To the extent affiliated transactions are permitted,
the Series will deal with Goldman Sachs and its affiliates on an arms-length
basis.

      Each Series will be required to establish business relationships with its
counterparties based on the Series' own credit standing. Neither Goldman Sachs
nor its affiliates will have any obligation to allow their credit to be used in
connection with a Series' establishment of its business relationships, nor is it
expected that a Series' counterparties will rely on the credit of Goldman Sachs
or any of its affiliates in evaluating the Series' creditworthiness.

      From time to time, Goldman Sachs or any of its affiliates may, but is not
required to, purchase and hold shares of a Series in order to increase the
assets of the Series. Increasing a Series' assets may enhance investment
flexibility and diversification and may contribute to economies of scale that
tend to reduce a Series' expense ratio. Goldman Sachs reserves the right to
redeem at any time some or all of the shares of a Series acquired for its own
account. A large redemption of shares of a Series by Goldman Sachs could
significantly reduce the asset size of the Series, which might have an adverse
effect on a Series' investment flexibility, portfolio diversification and
expense ratio. Goldman Sachs will consider the effect of redemptions on a Series
and other unitholders in deciding whether to redeem its units.

      It is possible that a Series' holdings will include securities of entities
for which Goldman Sachs performs investment banking services as well as
securities of entities in which Goldman Sachs makes a market. From time to time,
Goldman Sachs' activities may limit the Series' flexibility in purchases and
sales of securities. When Goldman Sachs is engaged in an underwriting or other
distribution of securities of an entity, the Series' investment advisers may be
prohibited from purchasing or recommending the purchase of certain securities of
that entity for the Series.

                             PORTFOLIO TRANSACTIONS

      GSAM places the portfolio transactions of the Series and of all other
accounts managed by GSAM for execution with many firms. GSAM uses its best
efforts to obtain execution of portfolio transactions at prices which are
advantageous to each Series and at reasonably competitive spreads or (when a
disclosed commission is being charged) at reasonably 


                                      -62-
<PAGE>
 
competitive commission rates. In seeking such execution, GSAM will use its best
judgment in evaluating the terms of a transaction, and will give consideration
to various relevant factors, including without limitation the size and type of
the transaction, the nature and character of the market for the security, the
confidentiality, speed and certainty of effective execution required for the
transaction, the general execution and operational capabilities of the
broker-dealer, the general execution and operational capabilities of the firm,
the reputation, reliability, experience and financial condition of the firm, the
value and quality of the services rendered by the firm in this and other
transactions, and the reasonableness of the spread or commission, if any.
Securities purchased and sold by the Series are generally traded in the
over-the-counter market on a net basis (i.e., without commission) through
broker-dealers and banks acting for their own account rather than as brokers, or
otherwise involve transactions directly with the issuer of such securities.

      Goldman Sachs is active as an investor, dealer and/or underwriter in many
types of municipal and money market instruments. Its activities in this regard
could have some effect on the markets for those instruments which the Series
buy, hold or sell. An order has been granted by the SEC under the Act which
permits the Series to deal with Goldman Sachs in transactions in certain taxable
securities in which Goldman Sachs acts as principal. As a result, the Series may
trade with Goldman Sachs as principal subject to the terms and conditions of
such exemption.

      Under the Act, the Series are prohibited from purchasing any instrument of
which Goldman Sachs is a principal underwriter during the existence of an
underwriting or selling syndicate relating to such instrument, absent an
exemptive order (the order referred to in the preceding paragraph will not apply
to such purchases) or the adoption of and compliance with certain procedures
under such Act. The Trust has adopted procedures which establish, among other
things, certain limitations on the amount of debt securities that may be
purchased in any single offering and on the amount of the Trust's assets that
may be invested in any single offering. Accordingly, in view of Goldman Sachs'
active role in the underwriting of debt securities, a Series' ability to
purchase debt securities in the primary market may from time to time be limited.

      In certain instances there may be securities which are suitable for more
than one Series as well as for one or more of the other clients of GSAM.
Investment decisions for each Series and for GSAM's other clients are made with
a view to achieving their respective investment objectives. It may develop that
a particular security is bought or sold for only one client even though it might
be held by, or bought or sold for, other clients. Likewise, a particular
security may be bought for one or more clients when one or more other clients
are selling that same security. Some simultaneous transactions are inevitable
when several clients receive investment advice from the same Investment Adviser,
particularly when the same security is suitable for the investment objectives of
more than one client. When two or more clients are simultaneously engaged in the
purchase or sale of the same security, the securities are allocated among
clients in a manner believed to be equitable to each. It is recognized that in
some cases this system could have a detrimental effect on the price or volume of
the security in a particular transaction as far as a Series is concerned. Each
Series believes that over time its ability to participate in volume transactions
will produce better executions for the Series.

                                 NET ASSET VALUE

      The net asset value per unit of each Series (except for FS Prime
Obligations Fund, FS Government Fund, FS Premium Fund and FS Treasury
Obligations Fund) is determined by the Series' custodian as of the close of
regular trading on the New York Stock Exchange (normally, but not always, 4:00
p.m. New York time) (in the case of the FS Prime Obligations Fund, FS Government
Fund, FS Premium Fund and FS Treasury Obligations Fund, net asset value is
determined normally, but not always, at 5:00 p.m. New York time) on each
Business Day. A Business Day means any day on which the New York Stock Exchange
is open, except for days on which Chicago, Boston or New York banks are closed
for local holidays. Such holidays include: New Year's Day, Martin Luther King,
Jr. Day, Presidents' Day, Good Friday, Memorial Day, the Fourth of July, Labor
Day, Columbus Day, Veteran's Day, Thanksgiving Day and Christmas Day.

      In the event that the New York Stock Exchange adopts different trading
hours on either a permanent or temporary basis, the Trustees will reconsider the
time at which net asset value is computed. In addition, each Series may compute
its net asset value as of any time permitted pursuant to any exemption, order or
statement of the SEC or its staff.

      Each Series' securities are valued using the amortized cost method of
valuation in an effort to maintain a constant net asset value of $ 1.00 per
unit, which the Board of Trustees has determined to be in the best interest of
each Series and its unitholders. This method involves valuing a security at cost
on the date of acquisition and thereafter assuming a constant accretion of a
discount or amortization of a premium to maturity, regardless of the impact of
fluctuating interest rates on the market value of the instrument. While this
method provides certainty in valuation, it may result in periods during which
value, as determined by amortized cost, is higher or lower than the price a
Series would receive if it sold the instrument. During such periods, the yield
to an investor in a Series may differ somewhat from that obtained in a similar
investment company which uses available market quotations to value all of its
portfolio securities. During periods of declining interest rates, the quoted
yield on units of a Series may tend to be higher than a like computation made by
a fund with identical investments utilizing a method of valuation based upon
market prices and estimates of market prices for all of its portfolio
instruments. Thus, if the use of amortized cost by a Series resulted in a lower
aggregate portfolio value on a particular day, a prospective investor in the
Series would be able to obtain a somewhat higher yield if he or she purchased
units of the Series on that day, than would result from investment in a fund
utilizing solely market values, and existing investors in the Series would
receive less investment income. The converse would apply in a period of rising
interest rates.

      The Trustees have established procedures designed to stabilize, to the
extent reasonably possible, each Series' price per unit as computed for the
purpose of sales and redemptions at $1.00. Such procedures include review of
each Series by the Trustees, at such intervals as they deem appropriate, to
determine whether the Series' net asset value calculated by using available
market quotations (or an appropriate substitute which reflects market
conditions) deviates from $1.00 per unit based on amortized cost, as well as
review of methods used to calculate the deviation. If such deviation exceeds 1/2
of 1%, the Trustees will promptly consider what action, 


                                      -65-
<PAGE>
 
if any, will be initiated. In the event the Trustees determine that a deviation
exists which may result in material dilution or other unfair results to
investors or existing unitholders, they will take such corrective action as they
regard to be necessary and appropriate, including the sale of portfolio
instruments prior to maturity to realize capital gains or losses or to shorten
average portfolio maturity; withholding part or all of dividends or payment of
distributions from capital or capital gains; redeeming units in kind; or
establishing a net asset value per unit by using available market quotations or
equivalents. In addition, in order to stabilize the net asset value per unit at
$1.00 the Trustees have the authority (1) to reduce or increase the number of
units outstanding on a pro rata basis, and (2) to offset each unitholder's pro
rata portion of the deviation between the net asset value per unit and $1.00
from the unitholder's accrued dividend account or from future dividends. Each
Series may hold cash for the purpose of stabilizing its net asset value per
unit. Holdings of cash, on which no return is earned, would tend to lower the
yield on such Series' units.

      In order to continue to use the amortized cost method of valuation for
each Series' investments, the Series must comply with Rule 2a-7. See "Investment
Restrictions."

      The proceeds received by each Series for each issue or sale of its units,
and all net investment income, realized and unrealized gain and proceeds
thereof, subject only to the rights of creditors, will be specifically allocated
to such Series and constitute the underlying assets of that Series. The
underlying assets of each Series will be segregated on the books of account, and
will be charged with the liabilities in respect to such Series and with a share
of the general liabilities of the Trust. Expenses with respect to the Series are
to be allocated in proportion to the net asset values of the respective Series
except where allocations of direct expenses can otherwise be fairly made. In
addition, within each Series, ILA Units, ILA Administration Units, ILA Service
Units, ILA Class B and Class C Units, ILA Cash Management Shares, FST Shares,
FST Administration Shares, FST Service Shares and FST Preferred Shares (if any)
will be subject to different expense structures (see "Organization and
Capitalization").

                                   REDEMPTIONS

      The Trust may suspend the right of redemption of units of a Series and may
postpone payment for any period: (i) during which the New York Stock Exchange is
closed for regular trading other than customary weekend and holiday closings or
during which trading on the New York Stock Exchange is restricted, (ii) when the
SEC determines that a state of emergency exists which may make payment or
transfer not reasonably practicable, (iii) as the SEC may by order permit for
the protection of the unitholders of the Trust or (iv) at any other time when
the Trust may, under applicable laws and regulations, suspend payment on the
redemption of the Series' units.

      The Trust agrees to redeem units of each Series solely in cash up to the
lesser of $250,000 or 1% of the net asset value of the Series during any 90-day
period for any one unitholder. The Trust reserves the right to pay other
redemptions, either total or partial, by a distribution in kind of securities
(instead of cash) from the applicable Series' portfolio. The securities
distributed in 


                                      -66-
<PAGE>
 
such a distribution would be valued at the same value as that assigned to them
in calculating the net asset value of the units being redeemed. If a unitholder
receives a distribution in kind, he or she should expect to incur transaction
costs when he or she converts the securities to cash.

      A FST shareholder of any Financial Square Fund with balances in excess of
$100 million may elect to have a special account with State Street for the
purpose of redeeming shares from its account in that Series by check. When State
Street receives a completed signature card and authorization form, the
shareholder will be provided with a supply of checks. Checks drawn on this
account may be payable to the order of any person in any amount of $500 or more,
but cannot be certified. The payee of the check may cash or deposit it like any
other check drawn on a bank. When such a check is presented to State Street for
payment, a sufficient number of full and fractional shares will be redeemed to
cover the amount of the check. Cancelled checks will be returned to the
shareholder by State Street. The Trust and Goldman Sachs each reserves the right
to waive the minimum requirement.

      The check redemption privilege enables a shareholder to receive the
dividends declared on the shares to be redeemed until such time as the check is
processed. Because of this feature, the check redemption privilege may not be
used for a complete liquidation of an account. If the amount of a check is
greater than the value of shares held in the shareholder's account, the check
will be returned unpaid, and the shareholder may be subject to extra charges.

      Goldman Sachs reserves the right to impose conditions on, limit the
availability of or terminate the check redemption privilege at any time with
respect to a particular shareholder or shareholders in general. The Trust and
State Street reserve the right at any time to suspend the check redemption
privilege and intend to do so in the event that federal legislation or
regulations impose reserve requirements or other restrictions deemed by the
Trustees to be adverse to the interests of the Series.

                         CALCULATION OF YIELD QUOTATIONS

      From time to time, each Series may advertise its yield, effective yield,
tax-equivalent yield, tax-equivalent effective yield and total return. Yield,
effective yield, tax-equivalent yield, tax-equivalent effective yield and total
return are calculated separately for each class of units of a Series. Each type
of unit is subject to different fees and expenses and may have differing yields
for the same period.

      Each Series' yield quotations are calculated by a standard method
prescribed by the rules of the SEC. Under this method, the yield quotation is
based on a hypothetical account having a balance of exactly one unit at the
beginning of a seven-day period.

      The yield of a Series refers to the income generated by an investment in
that Series over a seven-day period (which period will be stated in the
advertisement). This income is then annualized; that is, the amount of income
generated by the investment during that week is assumed to be generated each
week over a 52 week period and is shown as a percentage of the 


                                      -67-
<PAGE>
 
investment. The yield quotation is computed as follows: the net change,
exclusive of capital changes and income other than investment income (i.e.,
realized gains and losses from the sale of securities and unrealized
appreciation and depreciation), in the value of a hypothetical pre-existing
account having a balance of one unit at the beginning of the base period is
determined by dividing the net change in account value by the value of the
account at the beginning of the base period. This base period return is then
multiplied by 365/7 with the resulting yield figure carried to the nearest 100th
of 1%. Such yield quotation shall take into account all fees that are charged to
a Series.

      Each Series also may advertise a quotation of effective yield for a
7-calendar day period. Effective yield is computed by compounding the
unannualized base period return determined as in the preceding paragraph by
adding 1 to that return, raising the sum to the 365/7 power and subtracting one
from the result, according to the following formula:

      Effective Yield = [(base period return + 1)365/7] - 1

      The effective yield will be slightly higher than the yield because of the
compounding effect of reinvestment.

      The ILA Treasury Instruments Portfolio, ILA Federal Portfolio, ILA
Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California Portfolio, ILA
Tax-Exempt New York Portfolio, FS Treasury Instruments Fund, FS Federal Fund, FS
Tax-Free Fund and FS Municipal Fund may also advertise a tax-equivalent yield
and tax-equivalent effective yield. Tax-equivalent yield is computed by dividing
that portion of a Series' yield (as computed above) which is tax-exempt by one
minus a stated income tax rate and adding the quotient to that portion, if any,
of the yield of the Series that is not tax-exempt. Tax-equivalent effective
yield is computed by dividing that portion of a Series' effective yield (as
computed above) which is tax-exempt by one minus a stated income tax rate and
adding the quotient to that portion, if any, of the effective yield of the
Series that is not tax-exempt.

      Total return is determined by computing the percentage change in value of
$1,000 invested at the maximum public offering price for a specified period,
assuming reinvestment of all dividends and distributions at NAV. The total
return calculation assumes a complete redemption of the investment at the end of
the relevant period. Each Series may furnish total return calculations based on
cumulative, average, year-by-year or other basis for various specified periods
by means of quotations, charts, graphs or schedules.

      Unlike bank deposits or other investments which pay a fixed yield or
return for a stated period of time, the investment results for a Series are
based on historical performance and will fluctuate from time to time. Any
presentation of a Series' yield, effective yield, tax-equivalent yield,
tax-equivalent effective yield or total return for any prior period should not
be considered a representation of what an investment may earn or what a Series'
yield, effective yield, tax equivalent yield, tax equivalent effective yield or
total return may be in any future period. Return is a function of portfolio
quality, composition, maturity and market conditions as well as of the expenses
allocated to each Series. The return of a Series may not be comparable to other


                                      -68-

investment alternatives because of differences in the foregoing variables and
differences in the methods used to value portfolio securities, compute expenses
and calculate return.

      The quotations of tax-equivalent yield set forth above for the seven-day
period ended December 31, 1998 are based on a federal marginal tax rate of 40.8%
(adjusted for the 3% phase out of itemized deductions for individuals at high
income levels).

      With respect to the ILA Tax-Exempt California Portfolio, the California
top marginal State personal income tax rate of 5.62% (adjusted for the federal
income tax benefit) is being assumed in addition to the 40.8% federal tax rate,
for a combined tax rate of 46.42%. With respect to the ILA Tax-Exempt New York
Portfolio, the tax-equivalent and tax-equivalent effective yields are being
shown under three scenarios. The first scenario assumes, as noted above, a
federal marginal tax rate of 40.8%, the second scenario assumes a New York top
marginal State personal income tax rate of 4.14% (adjusted for the federal
income tax benefit), for a combined effective tax rate of 44.94%. The third
scenario assumes a New York City top marginal personal income tax rate of 2.69%
(adjusted for the federal income tax benefit) in addition to the above federal
and New York State tax rates, for a combined effective tax rate of 47.63%. The
combined tax rates assume full deductibility of state and, if applicable, city
taxes in computing federal tax liability.

      From time to time any Series may publish an indication of its past
performance as measured by independent sources such as (but not limited to)
Lipper Analytical Services, Incorporated, Weisenberger Investment Companies
Service, Donoghue's Money Fund Report, Barron's, Business Week, Changing Times,
Financial World, Forbes, Money, Morningstar Mutual Funds, Micropal, Personal
Investor, Sylvia Porter's Personal Finance, and The Wall Street Journal.

      The Trust may also advertise information which has been provided to the
NASD for publication in regional and local newspapers. In addition, the Trust
may from time to time advertise a Series' performance relative to certain
indices and benchmark investments, including (without limitation): inflation and
interest rates, certificates of deposit (CDs), money market deposit accounts
(MMDAs), checking accounts, savings accounts, repurchase agreements and
information prepared by recognized mutual fund statistical services. The Trust
may also compare a Series' performance with that of other mutual funds with
similar investment objectives.

      The composition of the investments in such mutual funds, comparative
indices and the characteristics of such benchmark investments are not identical
to, and in some cases are very different from, those of a Series. Indices and
averages are generally unmanaged and the items included in the calculations of
such indices and averages may not be identical to the formulas used by a Series
to calculate its performance data.

      A Series' performance data will be based on historical results and is not
intended to indicate future performance. A Series' performance will vary based
on market conditions, portfolio expenses, portfolio investments and other
factors. Return for a Series will fluctuate unlike certain bank deposits or
other investments which pay a fixed yield or return.

      The Trust may also, at its discretion, from time to time make a list of a
Series' holdings available to investors upon request. The Trust may from time to
time summarize the substance of discussions contained in shareholder reports in
advertisements and publish the Investment Adviser's views as to markets, the
rationale for a Series' investments and discussions of a Fund's current
holdings.

      In addition, from time to time, quotations from articles from financial
and other publications, such as those listed above, may be used in
advertisements, sales literature and in reports to unitholders.

      Information used in advertisement and materials furnished to present and
prospective investors may include statements or illustrations relating to the
appropriateness of certain types of securities and/or mutual funds to meet
specific financial goals. Such information may address:

o     cost associated with aging parents;

o     funding a college education (including its actual and estimated cost;

o     health care expenses (including actual and projected expenses);

o     long-term disabilities (including the availability of, and coverage
      provided by, disability insurance):

o     retirement (including the availability of social security benefits, the
      tax treatment of such benefits and statistics and other information
      relating to maintaining a particular standard of living and outliving
      existing assets);

o     asset allocation strategies and the benefits of diversifying among asset
      classes;

o     the benefits of international and emerging market investments;

o     the effects of inflation on investing and saving;

      standard deviation.

                                 TAX INFORMATION

      Each Series is treated as a separate entity for tax purposes, has elected
to be treated as a regulated investment company and intends to qualify for such
treatment for each taxable year under Subchapter M of the Code. If for any
taxable year a Series does not qualify as a regulated investment company, it
will be taxed on all of its investment company taxable income and net capital
gains at corporate rates, its net tax-exempt interest (if any) may be subject to
the alternative minimum tax, and its distributions to shareholders will be
taxable as ordinary dividends to the extent of its current and accumulated
earnings and profits.

      In order to qualify as a regulated investment company, each Series must,
among other things, (a) derive at least 90% of its gross income for the taxable
year from dividends, interest, payments with respect to securities loans and
gains from the sale or other disposition of stock or securities or certain other
investments (the "90% Test"); and (b) diversify its holdings so that, at the
close of each quarter of its taxable year, (i) at least 50% of the market value
of the Series' total gross assets is represented by cash and cash items
(including receivables), U.S. Government securities, securities of other
regulated investment companies and other securities limited, in respect of any
one issuer, to an amount not greater in value than 5% of the value of the
Series' total assets and not more than 10% of the outstanding voting securities
of such issuer, and (ii) not more than 25% of the value of the Series' total
(gross) assets is invested in the securities (other than U.S. Government
securities and securities of other regulated investment companies) of any one
issuer or two or more issuers controlled by the Series and engaged in the same,
similar or 


                                      -78-
<PAGE>
 
related trades or businesses. For purposes of these requirements, participation
interests will be treated as securities, and the issuer will be identified on
the basis of market risk and credit risk associated with any particular
interest. Certain payments received with respect to such interests, such as
commitment fees and certain facility fees, may not be treated as income
qualifying under the 90% test.

      Each Series, as a regulated investment company, will not be subject to
federal income tax on any of its net investment income and net realized capital
gains that are distributed to unitholders with respect to any taxable year in
accordance with the Code's timing and other requirements, provided that the
Series distributes at least 90% of its investment company taxable income
(generally, all of its net taxable income other than "net capital gain," which
is the excess of net long-term capital gain over net short-term capital loss)
for such year and, in the case of any Series that earns tax-exempt interest, at
least 90% of the excess of the tax-exempt interest it earns over certain
disallowed deductions. A Series will be subject to federal income tax at regular
corporate rates on any investment company taxable income or net capital gain
that it does not distribute for a taxable year. In order to avoid a
nondeductible 4% federal excise tax, each Series must distribute (or be deemed
to have distributed) by December 31 of each calendar year at least 98% of its
taxable ordinary income for such year, at least 98% of the excess of its capital
gains over its capital losses (generally computed on the basis of the one-year
period ending on October 31 of such year), and all taxable ordinary income and
the excess of capital gains over capital losses for the previous year that were
not distributed in such year and on which the Series paid no federal income tax.

      Dividends paid by a Series from taxable net investment income (including
income attributable to accrued market discount and a portion of the discount on
certain stripped tax-exempt obligations and their coupons) and the excess of net
short-term capital gain over net long-term capital loss will be treated as
ordinary income in the hands of unitholders. Such distributions will not qualify
for the corporate dividends-received deduction. Dividends paid by a Series from
the excess of net long-term capital gain (if any) over net short-term capital
loss are taxable to unitholders as long-term capital gain, regardless of the
length of time the units of a Series have been held by such unitholders, and
also will not qualify for the corporate dividends-received deduction. A Series'
net realized capital gains for a taxable year are computed by taking into
account realized capital losses, including any capital loss carryforward of that
Series. At December 31, 1998, the following Series had approximately the
following amounts of capital loss carryforwards:

                                            Amount        Year of Expiration

New York Portfolios, FS Tax-Free Fund or FS Municipal Fund from tax-exempt
interest received by them and properly designated as "exempt-interest dividends"
will generally be exempt from regular federal income tax, provided that at least
50% of the value of the applicable Series' total assets at the close of each
quarter of its taxable year consists of tax-exempt obligations, i.e.,
obligations described in Section 103(a) of the Code (not including units of
other regulated investment companies that may pay exempt-interest dividends,
because such units are not treated as tax-exempt obligations for this purpose).
Dividends paid by the other Series from any tax-exempt interest they may receive
will not be tax-exempt, because they will not satisfy the 50% requirement
described in the preceding sentence. A portion of any tax-exempt distributions
attributable to interest on certain "private activity bonds," if any, received
by a Series may constitute a tax preference items and may give rise to, or
increase liability under, the alternative minimum tax for particular
unitholders. In addition, all tax-exempt distributions of the Series may be
considered in computing the "adjusted current earnings" preference item of their
corporate unitholders in determining the corporate alternative minimum tax, and
will be taken into account in determining the extent to which a unitholder's
social security or certain railroad retirement benefits are taxable. To the
extent that the ILA Tax-Exempt Diversified, ILA Tax-Exempt California, ILA
Tax-Exempt New York Portfolios and FS Tax-Free and FS Municipal Funds invest in
certain short-term instruments, including repurchase agreements, the interest on
which is not exempt from Federal income tax, or earn other taxable income any
distributions of income from such investments or other taxable income will be
taxable to unitholders as ordinary income. All or substantially all of any
interest on indebtedness incurred directly or indirectly to purchase or carry
units of the Series will generally not be deductible. The availability of
tax-exempt obligations and the value of the Series may be affected by
restrictive tax legislation enacted in recent years.

      In purchasing municipal obligations, the ILA Tax-Exempt Diversified, ILA
Tax-Exempt California, ILA Tax-Exempt New York Portfolios, FS Tax-Free and FS
Municipal Funds rely on opinions of nationally-recognized bond counsel for each
issue as to the excludability of interest on such obligations from gross income
for federal income tax purposes and, where applicable, the tax-exempt nature of
such interest under the personal income tax laws of a particular state. These
Series do not undertake independent investigations concerning the tax-exempt
status of such obligations, nor do they guarantee or represent that bond
counsels' opinions are correct. Bond counsels' opinions will generally be based
in part upon covenants by the issuers and related parties regarding continuing
compliance with federal tax requirements. Tax laws not only limit the purposes
for which tax-exempt bonds may be issued and the supply of such bonds, but also
contain numerous and complex requirements that must be satisfied on a continuing
basis in order for bonds to be and remain tax-exempt. If the issuer of a bond or
a user of a bond-financed facility fails to comply with such requirements at any
time, interest on the bond could become taxable, retroactive to the date the
obligation was issued. In that event, a portion of a Fund's distributions
attributable to interest the Fund received on such bond for the current year and
for prior years could be characterized or recharacterized as taxable income.

      Distributions of net investment income and net realized capital gains will
be taxable as described above, whether received in units or in cash. Unitholders
electing to receive distributions in the form of additional units will have a
cost basis in each unit so received equal to the amount of cash they would have
received had they elected to receive cash.


                                      -80-
<PAGE>
 
      Certain Series may be subject to foreign taxes on their income (possibly
including, in some cases, capital gains) from securities. Tax conventions
between certain countries and the U.S. may reduce or eliminate such taxes in
some cases. However, neither the Series nor its unitholders will be able to
claim foreign tax credits with respect to any such taxes.

      Redemptions (including exchanges) and other dispositions of units in
transactions that are treated as sales for tax purposes will generally not
result in taxable gain or loss, provided that the Series successfully maintain a
constant net asset value per share, but a loss may be recognized to the extent a
CDSC is imposed on the redemption or exchange of ILA Class B or Class C Units.
All or a portion of such a loss may be disallowed under applicable Code
provisions in certain circumstances. Unitholders should consult their own tax
advisers with reference to their circumstances to determine whether a
redemption, exchange, or other disposition of Series' units is properly treated
as a sale for tax purposes.

      All distributions (including exempt-interest dividends), whether received
in units or cash, must be reported by each unitholder who is required to file a
federal income tax return. The Series will inform unitholders of the federal
income tax status of their distributions after the end of each calendar year,
including, in the case of the ILA Tax-Exempt Diversified Portfolio, ILA
Tax-Exempt California Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-Free
Fund and FS Municipal Fund the amounts that qualify as exempt-interest dividends
and any portions of such amounts that constitute tax preference items under the
federal alternative minimum tax. Unitholders who receive exempt-interest
dividends and have not held their units of the applicable Series for its entire
taxable year may have designated as tax-exempt or as a tax preference item a
percentage of their distributions which is not exactly equal to a proportionate
share of the amount of tax-exempt interest or tax preference income earned
during the period of their investment in such Series. Each unitholder should
consult his or her own tax advisor to determine the tax consequences of an
investment in a Series in the unitholder's own state and locality.

      Units of a Series that pays primarily exempt-interest dividends would not
be suitable for tax-exempt institutions and may not be suitable for retirement
plans qualified under Section 401 of the Code, H.R. 10 plans and individual
retirement accounts because such plans and accounts are generally tax-exempt
and, therefore, not only would the Unitholder not gain any additional benefit
from the Series' dividends being tax-exempt, but such dividends would be
ultimately taxable to the beneficiaries when distributed. In addition, a Series
that pays primarily exempt-interest dividends may not be an appropriate
investment for entities which are "substantial users" of facilities financed by
"private activity bonds" or "related persons" thereof. "Substantial user" is
defined under U.S. Treasury Regulations to include a non-exempt person who (i)
regularly uses a part of such facilities in his or her trade or business and
whose gross revenues derived with respect to the facilities financed by the
issuance of bonds are more than 5% of the total revenues derived by all users of
such facilities, (ii) occupies more than 5% of the usable area of such
facilities or (iii) are persons for whom such facilities or a part thereof were
specifically constructed, reconstructed or acquired. "Related persons" include
certain related natural persons, affiliated corporations, a partnership and its
partners and an S corporation and its shareholders.

      The foregoing discussion relates solely to U.S. federal income tax law as
it applies to U.S. persons (i.e., U.S. citizens and residents and U.S. domestic
corporations, partnerships, trusts and estates) subject to tax under such law.
The discussion does not address special tax rules applicable to certain classes
of investors, such as tax-exempt entities, insurance companies and financial
institutions. Each unitholder who is not a U.S. person should consult his or her
tax adviser regarding the U.S. and non-U.S. tax consequences of ownership of
units of a Series, including the possibility that such a unitholder may be
subject to a U.S. nonresident alien withholding tax at a rate of 30% (or at a
lower rate under an applicable U.S. income tax treaty) on certain distributions
from a Series and, if a current IRS Form W-8 or acceptable substitute is not on
file with the Series, may be subject to backup withholding on certain payments.

State and Local

      The Trust may be subject to state or local taxes in jurisdictions in which
the Trust may be deemed to be doing business. In addition, in those states or
localities which have income tax laws, the treatment of a Series and its
unitholders under such laws may differ from their treatment under Federal income
tax laws, and an investment in the Series may have tax consequences for
unitholders that are different from those of a direct investment in the Series'
securities. Unitholders should consult their own tax advisers concerning these
matters. For example, in such states or localities it may be appropriate for
unitholders to review with their tax advisers the state income and, if
applicable, intangible property tax consequences of investments by the Series in
securities issued by the particular state or the U.S. Government or its various
agencies or instrumentalities, because many states (i) exempt from personal
income tax distributions made by regulated investment companies from interest on
obligations of the particular state or on direct U.S. Government obligations
and/or (ii) exempt from intangible property tax the value of the units of such
companies attributable to such obligations, subject to certain state-specific
requirements and/or limitations. See also the discussion below of these
applicable provisions in California and New York.

      Provided that the Series qualify as regulated investment companies and
incur no federal income tax liability, the Series may still be subject to New
York State and City minimum taxes, which are small in amount.

      California State Taxation. The following discussion of California tax law
assumes that the ILA Tax-Exempt California Portfolio will be qualified as a
regulated investment company under Subchapter M of the Code and will be
qualified thereunder to pay exempt-interest dividends. The ILA Tax-Exempt
California Portfolio intends to qualify for each taxable year under California
law to pay "exempt-interest dividends" which will be exempt from the California
personal income tax.

      Individual unitholders of the ILA Tax-Exempt California Portfolio who
reside in California will not be subject to California personal income tax on
distributions received from the Portfolio to the extent such distributions are
exempt-interest dividends attributable to interest on obligations the interest
on which is exempt from California personal income tax provided that the
Portfolio satisfies the requirement of California law that at least 50% of its
assets at the close 


                                      -82-
<PAGE>
 
of each quarter of its taxable year be invested in such obligations and properly
designates such exempt-interest dividends under California Law. Distributions
from the ILA Tax-Exempt California Portfolio which are attributable to sources
other than those described in the second preceding sentence will generally be
taxable to such unitholders as ordinary income. Moreover, California legislation
which incorporates Subchapter M of the Code provides that capital gain dividends
may be treated as long-term capital gains. Such gains are currently subject to
personal income tax at ordinary income tax rates. Capital gains that are
retained by the Portfolio will be taxed to that Portfolio, and California
residents will receive no California personal income tax credit for such tax.
Distributions other than exempt-interest dividends are includable in income
subject to the California alternative minimum tax.

      Distributions from investment income and long-term and short-term capital
gains will generally not be excluded from taxable income in determining
California corporate franchise taxes for corporate unitholders and will be
treated as ordinary dividend income for such purposes. In addition, such
distributions may be includable in income subject to the alternative minimum
tax.

      Interest on indebtedness incurred or continued by unitholders to purchase
or carry units of the ILA Tax-Exempt California Portfolio will not be deductible
for California personal income tax purposes.

      In addition, any loss realized by a unitholder of the ILA Tax-Exempt
California Portfolio upon the sale of units held for six months or less may be
disallowed to the extent of any exempt-interest dividends received with respect
to such units. Moreover, any loss realized upon the redemption of units within
six months from the date of purchase of such units and following receipt of a
long-term capital gains distribution will be treated as long-term capital loss
to the extent of such long-term capital gains distribution. Finally, any loss
realized upon the redemption of units within thirty days before or after the
acquisition of other units of the same Portfolio may be disallowed under the
"wash sale" rules.

      New York City and State Taxation. Individual unitholders who are residents
of New York State will be able to exclude for New York State income tax purposes
that portion of the exempt-interest dividends properly designated as such from
the ILA Tax-Exempt New York Portfolio which is derived from interest on
obligations of New York State and its political subdivisions and obligations of
Puerto Rico, the U.S. Virgin Islands and Guam. Exempt-interest dividends may be
properly designated as such only if, as anticipated, at least 50% of the value
of the assets of the Portfolio are invested at the close of each quarter of its
taxable year in obligations of issuers the interest on which is excluded from
gross income for federal income tax purposes. Individual unitholders who are
residents of New York City will also be able to exclude such income for New York
City income tax purposes. Interest on indebtedness incurred or continued by a
shareholder to purchase or carry shares of the ILA Tax-Exempt New York Portfolio
is not deductible for New York State or New York City personal income tax
purposes. Distributions from the ILA Tax-Exempt New York Portfolio which are
attributable to sources other than those described in this paragraph will
generally be taxable to such unitholders as ordinary income.


                                      -83-
<PAGE>
 
      Long-term capital gains, if any, that are distributed by the ILA
Tax-Exempt New York Portfolio and are properly designated as capital gain
dividends will be treated as capital gains for New York State and City income
tax purposes in the hands of New York State and New York City residents.

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

      This discussion of the tax treatment of the Portfolio and its unitholders
is based on the tax laws in effect as of the date of this Statement of
Additional Information.

                         ORGANIZATION AND CAPITALIZATION

      Each Series is a series of Goldman Sachs Trust, a Delaware business trust,
established by a Declaration of Trust dated January 28, 1997. The Series were
previously a series of Goldman Sachs Money Market Trust, a Massachusetts
business trust, and were reorganized into the Trust as of April 30, 1997.

      The Trustees have authority under the Trust's Declaration of Trust to
create and classify shares of beneficial interest in separate series, without
further action by shareholders. The Act requires that where more than one class
or series of units exists, each class or series must be preferred over all other
classes or series in respect of assets specifically allocated to such class or
series. The Trustees also have authority to classify and reclassify any series
of units into one or more classes of units. As of the date of this Statement of
Additional Information, the Trustees have authorized the issuance of up to three
classes of units of each of the ILA Portfolios: ILA Units, ILA Administration
Units and ILA Service Units. In addition, the Trustees have authorized a fourth
and fifth class of units, ILA Class B Units and ILA Class C Units, with respect
to the Prime Obligations Portfolio. The Trustees have also authorized Cash
Management Shares of the ILA Prime Obligations Portfolio, ILA Money Market
Portfolio, ILA Government Portfolio, ILA Tax-Exempt Diversified Portfolio, ILA
Tax-Exempt California Portfolio and ILA Tax-Exempt New York Portfolio. As of the
date of this Statement of Additional Information, the Trustees have authorized
the issuance of up to four classes of shares of each of the Financial Square
Funds: FST Shares, FST Service Shares, FST Administration Shares and FST
Preferred Shares.

      Each ILA Unit, ILA Administration Unit, ILA Service Unit, ILA Class B
Unit, ILA Class C Unit, Cash Management Share, FST Share, FST Administration
Share, FST Service Share and FST Preferred Share of a Series represents an equal
proportionate interest in the assets belonging to that Series. It is
contemplated that most units (other than ILA Class B or Class C Units) will be
held in accounts of which the record owner is a bank or other institution
acting, directly or through an agent, as nominee for its customers who are the
beneficial owners of the units or another organization designated by such bank
or institution. ILA Class B and Class C Units generally are only issued upon
exchange from Class B or Class C Shares, respectively, of other Series of the
Goldman Sachs mutual funds. ILA Units and FST Shares may be purchased for


                                      -84-
<PAGE>
 
accounts held in the name of an investor or institution that is not compensated
by the Trust for services provided to the institution's investors. ILA
Administration Units and FST Administration Shares may be purchased for accounts
held in the name of an investor or an institution that provides certain account
administration services to its customers, including maintenance of account
records and processing orders to purchase, redeem and exchange ILA
Administration Units or FST Administration Shares. ILA Administration Units of
each ILA Portfolio bear the cost of administration fees at the annual rate of up
to .15 of 1% of the average daily net assets of such Units. FST Administration
Shares of a Financial Square Fund bear the cost of administration fees at the
annual rate of up to .25 of 1% of the average daily net assets of such Shares.
ILA Service Units and FST Service Shares may be purchased for accounts held in
the name of an institution that provides certain account administration and
unitholder liaison services to its customers, including maintenance of account
records, processing orders to purchase, redeem and exchange ILA Service Units or
FST Service Shares, responding to customer inquiries and assisting customers
with investment procedures. ILA Service Units bear the cost of service fees at
the annual rate of up to .40 of 1% of the average daily net assets of such
Units. FST Service Shares of a Financial Square Fund bear the cost of service
fees at the annual rate of up to .50 of 1% of the average daily net assets of
such Shares. FST Preferred Shares may be purchased for accounts held in the name
of an institution that provides certain account administration services to its
customers, including acting directly or through an agent, as the sole
shareholder of record, maintaining account records of its customers and
processing orders to purchase, redeem and exchange FST Preferred Shares. FST
Preferred Shares of a Financial Square Fund bear the cost of preferred
administration fees at an annual rate of up to 0.10% of the average daily net
assets of such shares. ILA Class B Units of the Prime Obligations Portfolio are
sold subject to a contingent deferred sales charge of up to 5.0%, and ILA Class
C Units are sold subject to a contingent deferred sales charge of 1.0% if
redeemed within 12 months of purchase. ILA Class B and Class C Units are sold
primarily through brokers and dealers who are members of the National
Association of Securities Dealers Inc. and certain other financial services
firms that have sales arrangements with Goldman Sachs. ILA Class B and Class C
Units bear the cost of distribution (Rule 12b-1) fees at the aggregate rate of
up to 0.75% of the average daily net assets attributable to ILA Class B and
Class C Units, respectively. ILA Class B and Class C Units also bear the cost of
service fees at an annual rate of up to 0.25% of the average daily net assets of
the Prime Obligations Portfolio attributable to ILA Class B and Class C Units.
Cash Management Shares may be purchased for accounts held in the name of an
institution that provides certain account administration and shareholder liaison
services to its customers, including maintenance of account records, processing
orders to purchase, redeem and exchange Cash Management Shares, responding to
customer inquiries and assisting customers with investment procedures. Cash
Management Shares bear the cost of service fees at the annual rate of up to
0.50% of the average daily net assets of such shares. Cash Management Shares
also bear the cost of distribution (Rule 12b-1) fees at an annual rate of 0.50%
of the average daily net assets attributable to Cash Management Shares. In
addition, each class of ILA units bears its own transfer agency expenses.

      It is possible that an institution or its affiliates may offer different
classes of units to its customers and thus receive different compensation with
respect to different classes of units of the same Series. In the event a Series
is distributed by salespersons or any other persons, they may 


                                      -85-
<PAGE>
 
receive different compensation with respect to different classes of units of the
Series. ILA Administration Units, ILA Service Units, ILA Class B Units, ILA
Class C Units, Cash Management Shares, FST Administration Shares, FST Preferred
Shares and FST Service Shares each have certain exclusive voting rights on
matters relating to their respective plans. Units of each class may be exchanged
only for units of the same class in another ILA Portfolio or, in the case of the
Prime Obligations Portfolio, shares of the corresponding class of certain other
mutual funds sponsored by Goldman Sachs. Except as described above, the ten
classes of units are identical. Certain aspects of the Units may be altered,
after advance notice to unitholders, if it is deemed necessary in order to
satisfy certain tax regulatory requirements.

      Rule 18f-2 under the Act provides that any matter required to be submitted
by the provisions of the Act or applicable state law, or otherwise, to the
holders of the outstanding voting securities of an investment company such as
the Trust shall not be deemed to have been effectively acted upon unless
approved by the holders of a majority of the outstanding units of each class or
series affected by such matter. Rule 18f-2 further provides that a class or
series shall be deemed to be affected by a matter unless the interests of each
class or series in the matter are substantially identical or the matter does not
affect any interest of such class or series. However, Rule 18f-2 exempts the
selection of independent public accountants, the approval of principal
distribution contracts and the election of directors from the separate voting
requirements of Rule 18f-2.

      When issued units are fully paid and non-assessable. In the event of
liquidation, unitholders of each class are entitled to share pro rata in the net
assets of the applicable Series available for distribution to the unitholders of
such class. All units are freely transferable and have no preemptive,
subscription or conversion rights.

      In the interest of economy and convenience, the Trust does not issue
certificates representing interests in the Series units or shares, as
appropriate. Instead, the transfer agent maintains a record of each unitholder's
or shareholder's ownership. Each unitholder or shareholder receives confirmation
of purchase and redemption orders from the transfer agent. Units and shares
representing interests in a particular Series and any dividends and
distributions paid by a Series are reflected in account statements from the
transfer agent.

      The Trust is not required to hold annual meetings of shareholders and does
not intend to hold such meetings. In the event that a meeting of shareholders is
held, each share of the Trust will be entitled, as determined by the Trustees
without the vote or consent of shareholders, either to one vote for each share
or to one vote for each dollar of net asset value represented by such shares on
all matters presented to unitholders including the election of Trustees (this
method of voting being referred to as "dollar based voting"). However, to the
extent required by the Act or otherwise determined by the Trustees, series and
classes of the Trust will vote separately from each other. Shareholders of the
Trust do not have cumulative voting rights in the election of Trustees. Meetings
of shareholders of the Trust, or any series or class thereof, may be called by
the Trustees, certain officers or upon the written request of holders of 10% or
more of the shares entitled to vote at such meetings. The Trustees will call a
special meeting of shareholders for the purpose of electing Trustees if, at any
time, less than a majority of Trustees holding office at the 


                                      -86-
<PAGE>
 
time were elected by shareholders. The shareholders of the Trust will have
voting rights only with respect to the limited number of matters specified in
the Declaration of Trust and such other matters as the Trustees may determine or
may be required by law.

      The Declaration of Trust provides for indemnification of Trustees,
officers and agents of the Trust unless the recipient is adjudicated (i) to be
liable by reason of willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of such person's office or (ii)
not to have acted in good faith in the reasonable belief that such person's
actions were in the best interest of the Trust. The Declaration of Trust
provides that, if any shareholder or former shareholder of any series is held
personally liable solely by reason of being or having been a shareholder and not
because of the shareholder's acts or omissions or for some other reason, the
shareholder or former shareholder (or heirs, executors, administrators, legal
representatives or general successors) shall be held harmless from and
indemnified against all loss and expense arising from such liability. The Trust
acting on behalf of any affected series, must, upon request by such shareholder,
assume the defense of any claim made against such shareholder for any act or
obligation of the series and satisfy any judgment thereon from the assets of the
series.

      The Declaration of Trust permits the termination of the Trust or of any
series or class of the Trust (i) by a majority of the affected shareholders at a
meeting of shareholders of the Trust, series or class; or (ii) by a majority of
the Trustees without shareholder approval if the Trustees determine that such
action is in the best interest of the Trust or its shareholders. The factors and
events that the Trustees may take into account in making such determination
include (i) the inability of the Trust or any respective series or class to
maintain its assets at an appropriate size; (ii) changes in laws or regulations
governing the Trust, or any series or class thereof, or affecting assets of the
type in which it invests; or (iii) economic developments or trends having a
significant adverse impact on their business or operations.

      The Declaration of Trust authorizes the Trustees without shareholder
approval to cause the Trust, or any series thereof, to merge or consolidate with
any corporation, association, trust or other organization or sell or exchange
all or substantially all of the property belonging to the Trust or any series
thereof. In addition, the Trustees, without shareholder approval, may adopt a
"master-feeder" structure by investing all or a portion of the assets of a
series of the Trust in the securities of another open-end investment company.

      The Declaration of Trust permits the Trustees to amend the Declaration of
Trust without a shareholder vote. However, shareholders of the Trust have the
right to vote on any amendment (i) that would affect the voting rights of
shareholders, (ii) that is required by law to be approved by shareholders; (iii)
that would amend the voting provisions of the Declaration of Trust; or (iv) that
the Trustees determine to submit to shareholders.

      The Trustees may appoint separate Trustees with respect to one or more
series or classes of the Trust's shares (the "Series Trustees"). To the extent
provided by the Trustees in the appointment of Series Trustees, Series Trustees
(a) may, but are not required to, serve as Trustees of the Trust or any other
series or class of the Trust; (b) may have, to the exclusion of any other


                                      -87-
<PAGE>
 
Trustee of the Trust, all the powers and authorities of Trustees under the
Declaration of Trust with respect to any other series or class; and/or (c) may
have no power or authority with respect to any other series or class. The
Trustees are not currently considering the appointment of Series Trustees for
the Trust.

Unitholder and Trustee Liability

      Under Delaware law, the unitholders of the Series are not generally
subject to liability for the debts or obligations of the Trust. Similarly,
Delaware law provides that a series of the Trust will not be liable for the
debts or obligations of any other series of the Trust. However, no similar
statutory or other authority limiting business trust unitholder liability exists
in many other states. As a result, to the extent that a Delaware business trust
or a unitholder is subject to the jurisdiction of courts of such other states,
the courts may not apply Delaware law and may thereby subject the Delaware
business trust unitholders to liability. To guard against this risk, the
Declaration of Trust contains express disclaimer of unitholder liability for
acts or obligations of a Series. Notice of such disclaimer will normally be
given in each agreement, obligation or instrument entered into or executed by a
Portfolio or the Trustees. The Declaration of Trust provides for indemnification
by the relevant Series for all loss suffered by a unitholder as a result of an
obligation of the Series. The Declaration of Trust also provides that a Series
shall, upon request, assume the defense of any claim made against any unitholder
for any act or obligation of the Series and satisfy any judgment thereon. In
view of the above, the risk of personal liability of unitholders is remote.

      In addition to the requirements set forth under Delaware Law, the
Declaration of Trust provides that unitholders may bring a derivative action on
behalf of the Trust only if the following conditions are met: (a) unitholders
eligible to bring such derivative action under Delaware law who hold at least
10% of the outstanding units of the Trust, or 10% of the outstanding units of
the series or class to which such action relates, must join in the request for
the Trustees to commence such action; and (b) the Trustees must be afforded a
reasonable amount of time to consider such unitholder request and to investigate
the basis of such claim. The Trustees will be entitled to retain counsel or
other Investment Advisers in considering the merits of the request and may
require an undertaking by the unitholders making such request to reimburse the
Trust for the expense of any such Investment Advisers in the event that the
Trustees determine not to bring such action.


                                      -90-
<PAGE>
 
      The Declaration of Trust further provides that the Trustees will not be
liable for errors of judgment or mistakes of fact or law, but nothing in the
Declaration of Trust protects a Trustee against liability to which he or she
would otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties involved in the conduct of his
or her office.

                           CUSTODIAN AND SUBCUSTODIAN

      State Street Bank and Trust Company ("State Street") has been retained to
act as custodian of the Series' assets. In that capacity, State Street maintains
the accounting records and calculates the daily net asset value per unit of the
Series. Its mailing address is P.O. Box 1713, Boston, MA 02105. State Street has
appointed The Northern Trust Company, 50 South LaSalle Street, Chicago, Illinois
60675 as subcustodian to hold cash and certain securities purchased by the
Trust.

                             INDEPENDENT ACCOUNTANTS

                                OTHER INFORMATION

      The Investment Adviser, Distributor and/or their affiliates may pay, out
of their own assets, compensation to Authorized Dealers, Service Organizations
and financial intermediaries ("Intermediaries") in connection with the sale,
distribution and/or servicing of shares of the Series. These payments
("Additional Payments") would be in addition to the payments by the Series
described in the Series' Prospectuses and this Additional Statement for
distribution and shareholder servicing and processing. These Additional Payments
may take the form of "due diligence" payments for an institution's examination
of the Series and payments for providing extra employee training and information
relating to the Series; "listing" fees for the placement of the Series on a


                                      -91-
<PAGE>
 
dealer's list of mutual funds available for purchase by its customers; "finders"
or "referral" fees for directing investors to the Series; "marketing support"
fees for providing assistance in promoting the sale of the Series' shares; and
payments for the sale of shares and/or the maintenance of share balances. In
addition, the Investment Adviser, Distributor and/or their affiliates may make
Additional Payments for subaccounting, administrative and/or shareholder
processing services that are in addition to any shareholder servicing and
processing fees paid by the Series. The Additional Payments made by the
Investment Adviser, Distributor and their affiliates may be a fixed dollar
amount, may be based on the number of customer accounts maintained by an
Intermediary, or may be based on a percentage of the value of shares sold to, or
held by, customers of the Intermediary involved, and may be different for
different Intermediaries. Furthermore, the Investment Adviser, Distributor
and/or their affiliates may contribute to various non-cash and cash incentive
arrangements to promote the sale of shares, as well as sponsor various
educational programs, sales contests and/or promotions. The Investment Adviser,
Distributor and their affiliates may also pay for the travel expenses, meals,
lodging and entertainment of Intermediaries and their salespersons and guests in
connection with educational, sales and promotional programs, subject to
applicable NASD regulations. The Distributor currently expects that such
additional bonuses or incentives will not exceed 0.50% of the amount of any
sales.

      As stated in the Prospectuses, the Trust may authorize Service
Organizations and other institutions that provide recordkeeping, reporting and
processing services to their customers to accept on the Trust's behalf purchase,
redemption and exchange orders placed by or on behalf of their customers and, if
approved by the Trust, to designate other intermediaries to accept such orders.
These institutions may receive payments from the Trust or Goldman Sachs for
their services. In some, but not all, cases these payments will be pursuant to
an Administration, Distribution or Service Plan described in the Prospectuses
and the following sections. Certain Service Organizations or institutions may
enter into sub-transfer agency agreements with the Trust or Goldman Sachs with
respect to their services.

      The Prospectuses and this Additional Statement do not contain all the
information included in the Registration Statement filed with the SEC under the
1933 Act with respect to the securities offered by the Prospectuses. Certain
portions of the Registration Statement have been omitted from the Prospectuses
and this Additional Statement pursuant to the rules and regulations of the SEC.

                              ADMINISTRATION PLANS
     (ILA Administration, FST Administration and FST Preferred Shares Only)

      The Trust, on behalf of each ILA Portfolio and Financial Square Fund, has
adopted an administration plan with respect to the ILA Administration Units (the
"ILA Administration Plan"), with respect to the FST Administration Shares (the
"FST Administration Plan") and with respect to FST Preferred Shares (the "FST
Preferred Plan," together with the ILA Administration Plan and the FST
Administration Plan, the "Administration Plans") which authorize the ILA
Portfolios and Financial Square Funds to compensate Service Organizations for
providing certain account administration services to their customers who are
beneficial owners of such units. Pursuant to the Administration Plans, the
Trust, on behalf of each Series, enters into agreements with Service
Organizations which purchase ILA Administration Units, FST Administration Shares
or FST Preferred Shares on behalf of their customers ("Service Agreements").
Under such Service Agreements, the Service Organizations may: (a) act, directly
or through an agent, as the sole unitholder of record and nominee for all
customers, (b) maintain account records for each customer who beneficially owns
ILA Administration Units, FST Administration Shares or FST Preferred Shares, (c)
answer questions and handle correspondence from customers regarding their
accounts, (d) process customer orders to purchase, redeem and exchange ILA
Administration Units, FST Administration Shares or FST Preferred Shares, and
handle the transmission of funds representing the customers' purchase price or
redemption proceeds, and (e) issue confirmations for transactions in units by
customers. As compensation for such services, the Trust on behalf of each ILA
Portfolio and Financial Square Fund pays each Service Organization an
administration fee in an amount up to .15% (on an annualized basis) of the
average daily net assets of the ILA Administration Units of each ILA Portfolio,
 .25% (on an annualized basis) of the average daily net assets of the FST
Administration Shares and .10% (on an annualized basis) of the average daily net
assets of the FST Preferred Shares of each Financial Square Fund, attributable
to or held in the name of such Service Organization for its customers. The
Trust, on behalf of the Series, accrues payments made pursuant to a Service
Agreement daily. All inquiries of beneficial owners of Administration Shares
should be directed to the owners' Service Organization.

      Conflict of interest restrictions (including the Employee Retirement
Income Security Act of 1974) may apply to a Service Organization's receipt of
compensation paid by the Trust in connection with the investment of fiduciary
funds in ILA Administration Units, FST Administration Shares and FST Preferred
Shares. Service Organizations, including banks regulated by the Comptroller of
the Currency, the Federal Reserve Board or the Federal Deposit Insurance
Corporation, and Investment Advisers and other money managers subject to the
jurisdiction of the Securities and Exchange Commission, the Department of Labor
or State Securities Commissions, are urged to consult legal advisers before
investing fiduciary assets in ILA Administration Units, FST Administration
Shares or FST Preferred Shares. In addition, under some state securities laws,
banks and other financial institutions purchasing ILA Administration Units, FST
Administration Shares or FST Preferred Shares on behalf of their customers may
be required to register as dealers.

      The Trustees of the Trust, including a majority of the Trustees who are
not interested persons of the Trust and who have no direct or indirect financial
interest in the operation of the Administration Plans or the related Service
Agreements, most recently voted to approve the Administration Plans and Service
Agreements at a meeting called for the purpose of voting on such Administration
Plans and Service Agreements on April 27, 1999. The Administration Plans and
Service Agreements will remain in effect until May 1, 2000 and continue in
effect thereafter only if such continuance is specifically approved annually by
a vote of the Trustees in the manner described above.

      An Administration Plan may not be amended to increase materially the
amount to be spent for the services described therein without approval of the
ILA Administration, FST Administration or FST Preferred shareholders of the
affected Series, and all material amendments of the Administration Plan must
also be approved by the Trustees in the manner 


                                      -95-
<PAGE>
 
described above. An Administration Plan may be terminated at any time by a
majority of the Trustees as described above or by vote of a majority of the
outstanding ILA Administration Units, FST Administration Shares or FST Preferred
Shares of the affected Series. The Service Agreements may be terminated at any
time, without payment of any penalty, by vote of a majority of the Trustees as
described above or by a vote of a majority of the outstanding ILA Administration
Units, FST Administration Shares or FST Preferred Shares of the affected Series
on not more than sixty (60) days' written notice to any other party to the
Service Agreements. The Service Agreements shall terminate automatically if
assigned. So long as the Administration Plans are in effect, the selection and
nomination of those Trustees who are not interested persons shall be committed
to the discretion of the Trust's Nominating Committee, which consists of all of
the non-interested members of the Board of Trustees. The Trustees have
determined that, in their judgment, there is a reasonable likelihood that the
Administration Plans will benefit the Series and holders of ILA Administration
Units, FST Administration Shares and FST Preferred Shares of such Series.

                                  SERVICE PLANS
     (ILA Service Units, Cash Management Shares and FST Service Shares Only)

      The Trust has adopted a service plan on behalf of each ILA Portfolio with
respect to the ILA Service Units (the "ILA Service Plan"), on behalf of the ILA
Prime Obligations Portfolio, ILA Money Market Portfolio, ILA Government
Portfolio, ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio and ILA Tax-Exempt New York Portfolio with respect to the Cash
Management Shares (the "Cash Management Shares Service Plan") and on behalf of
each Financial Square Fund with respect to the FST Service Shares (the "FST
Service Plan" and together with the ILA Service Plan and the Cash Management
Shares Service Plan, the "Service Plans") which authorize the Series to
compensate Service Organizations for providing certain account administration
and personal account maintenance services to their customers who are or may
become beneficial owners of such units. Pursuant to the Service Plans, the
Trust, on behalf of each ILA Portfolio or Financial Square Fund, enters into
agreements with Service Organizations which purchase ILA Service Units, Cash
Management Shares or FST Service Shares on behalf of their customers ("Service
Agreements"). Under such Service Agreements the Service Organizations may: (a)
act, directly or through an agent, as the sole unitholder of record and nominee
for all customers; (b) maintain account records for each customer who
beneficially owns ILA Service Units, Cash Management Shares or FST Service
Shares; (c) answer questions and handle correspondence from customers regarding
their accounts; (d) process customer orders to purchase, redeem and exchange ILA
Service Units, Cash Management Shares or FST Service Shares, and handle the
transmission of funds representing the customers' purchase price or redemption
proceeds; (e) issue confirmations for transactions in units by customers; (f)
provide facilities to answer questions from prospective and existing investors
about ILA Service Units, Cash Management Shares or FST Service Shares; (g)
receive and answer investor correspondence, including requests for prospectuses
and statements of additional information; (h) display and make prospectuses
available on the Service Organization's premises; (i) assist customers in
completing application forms, selecting dividend and other account options and
opening custody accounts with the Service Organization; (j) act as liaison
between customers and 


                                      -96-
<PAGE>
 
the Trust, including obtaining information from the Trust, working with the
Trust to correct errors and resolve problems and providing statistical and other
information to the Trust; and (k) with respect to the Cash Management Shares
Service Plan: (i) provide services to customers intended to facilitate or
improve their understanding of the benefits and risks of an ILA Portfolio, (ii)
facilitate the inclusion of an ILA Portfolio in investment, retirement, asset
allocation, cash management or sweep accounts or similar products or services
offered to customers by or through Service Organizations, (iii) facilitate
electronic or computer trading and/or processing in an ILA Portfolio or
providing electronic, computer or other database information regarding an ILA
Portfolio to customers, and (iv) develop, maintain and support systems necessary
to support Cash Management Shares. As compensation for such services, (a) the
Trust on behalf of each ILA Portfolio pays each Service Organization a service
fee in an amount up to .40% (on an annualized basis) of the average daily net
assets of the ILA Service Units of each ILA Portfolio attributable to or held in
the name of such Service Organization for its customers; provided, however, that
the fee paid for personal and account maintenance services shall not exceed .25%
of such average daily net assets; (b) the Trust on behalf of each ILA Portfolio
pays each Service Organization a service fee in an amount up to .50% (on an
annual basis) of the average daily net assets of the Cash Management Shares of
each ILA Portfolio attributable to or held in the name of such Service
Organization for its customers; provided, however, that the fee paid for
personal and account maintenance services shall not exceed .25% of such average
daily net assets; and (c) the Trust, on behalf of each Financial Square Fund,
pays each Service Organization a service fee in an amount up to .50% (on an
annualized basis) of the average daily net assets of the FST Service Shares of
each Financial Square Fund attributable to or held in the name of such Service
Organization for its customers; provided, however, that the fee paid for
personal and account maintenance services shall not exceed .25% of such average
daily net assets. The Trust, on behalf of the Series, accrues payments made
pursuant to a Service Agreement daily. All inquiries of beneficial owners of
Service Shares should be directed to the Owners' Service Organization.

As of December 31, 1998, FS Municipal Fund had not commenced operations.

      The Trust has adopted each Service Plan pursuant to Rule 12b-1 under the
Act in order to avoid any possibility that payments to the Service Organizations
pursuant to the Service Agreements might violate the Act. Rule 12b-1, which was
adopted by the Securities and Exchange Commission under the Act, regulates the
circumstances under which an investment company such as the Trust may bear
expenses associated with the distribution of its securities. In particular, such
an investment company cannot engage directly or indirectly in financing any
activity which is primarily intended to result in the sale of securities issued
by the company unless it has adopted a plan pursuant to, and complies with the
other requirements of, such Rule. The Trust believes that fees paid for the
services provided in the Service Plans and described above are not expenses
incurred primarily for effecting the distribution of ILA Service Units, Cash
Management Shares or FST Service Shares. However, should such payments be deemed
by a court or the Securities and Exchange Commission to be distribution
expenses, such payments would be duly authorized by the Service Plans.

      The Glass-Steagall Act prohibits all entities which receive deposits from
engaging to any extent in the business of issuing, underwriting, selling or
distributing securities, although institutions such as national banks are
permitted to purchase and sell securities upon the order and for the account of
their customers. Should future legislative or administrative action or judicial
or administrative decisions or interpretations prohibit or restrict the
activities of one or more of the Service Organizations in connection with the
Trust, such Service Organizations might be required to alter materially or
discontinue the services performed under their Service Agreements. If one or
more of the Service Organizations were restricted from effecting purchases or
sales of ILA Service Units, Cash Management Shares or FST Service Shares


                                      -99-
<PAGE>
 
automatically pursuant to pre-authorized instructions, for example, effecting
such transactions on a manual basis might affect the size and/or growth of the
Series. In addition, state securities laws on this issue may differ from the
interpretations of federal law expressed herein and banks and other financial
institutions purchasing ILA Service Units, Cash Management Shares or FST Service
Shares on behalf of their customers may be required to register as dealers
pursuant to state law. Any such alteration or discontinuance of services could
require the Trustees of the Trust to consider changing the Trust's method of
operations or providing alternative means of offering ILA Service Units, Cash
Management Shares or FST Service Shares to customers of such Service
Organizations, in which case the operation of the Trust, its size and/or its
growth might be significantly altered. It is not anticipated, however, that any
alteration of the Trust's operations would have any effect on the net asset
value per unit or result in financial losses to any unitholder or shareholder.

      Conflict of interest restrictions (including the Employee Retirement
Income Security Act of 1974) may apply to a Service Organization's receipt of
compensation paid by the Trust in connection with the investment of fiduciary
funds in ILA Service Units, Cash Management Shares or FST Service Shares.
Service Organizations, including banks regulated by the Comptroller of the
Currency, the Federal Reserve Board or the Federal Deposit Insurance
Corporation, and Investment Advisers and other money managers subject to the
jurisdiction of the Securities and Exchange Commission, the Department of Labor
or State Securities Commissions, are urged to consult legal advisers before
investing fiduciary assets in ILA Service Units, Cash Management Shares or FST
Service Shares.

      The Trustees of the Trust, including a majority of the Trustees who are
not interested persons of the Trust and who have no direct or indirect financial
interest in the operation of the Service Plans or the related Service
Agreements, most recently voted to approve the Service Plans and Service
Agreements at a meeting called for the purpose of voting on such Service Plans
and Service Agreements on April 27, 1999. The ILA Service Plan and FST Service
Plan and Service Agreements will remain in effect until May 1, 2000, and the
Cash Management Service Plan and Service Agreement will remain in effect until
April 30, 2000. The Service Plans and Service Agreements will continue in effect
thereafter only if such continuance is specifically approved annually by a vote
of the Trustees in the manner described above.

      A Service Plan may not be amended to increase materially the amount to be
spent for the services described therein without approval of the ILA Service
Unitholders, Cash Management Shareholders or FST Service Shareholders of the
affected Series, and all material amendments of a Plan must also be approved by
the Trustees in the manner described above. A Service Plan may be terminated at
any time by a majority of the Board of Trustees as described above or by vote of
a majority of the outstanding ILA Service Units, Cash Management Shareholders or
FST Service Shares of the affected Series. The Service Agreements may be
terminated at any time, without payment of any penalty, by vote of a majority of
the Board of Trustees as described above or by a vote of a majority of the
outstanding ILA Service Units, Cash Management Shareholders or FST Service
Shares of the affected Series on not more than sixty (60) days' written notice
to any other party to the Service Agreements. The Service Agreements shall
terminate automatically if assigned. As long as the Service Plans are in effect,
the selection and 


                                     -100-

nomination of those Trustees who are not interested persons shall be determined
by the discretion of the Trust's Nominating Committee, which consists of all of
the non-interested members of the Board of Trustees. The Trustees have
determined that, in their judgment, there is a reasonable likelihood that the
Service Plans will benefit the Series and holders of ILA Service Units, Cash
Management Shares and FST Service Shares of such Series.

                         DISTRIBUTION AND SERVICE PLANS

      Distribution and Service Plans. As described in the Prospectuses, the
Trust has adopted distribution and service plans pursuant to Rule 12b-1 under
the Act with respect to ILA Class B and Class C Units on behalf of the ILA Prime
Obligations Portfolio (the "Distribution and Service Plans").

      The Distribution and Service Plans were most recently approved on April
27, 1999 by a majority vote of the Trustees of the Trust, including a majority
of the non-interested Trustees of the Trust who have no direct or indirect
financial interest in the Distribution and Service Plans, cast in person at a
meeting called for the purpose of approving the Distribution and Service Plans.

      The compensation payable under the Distribution and Service Plans may not
exceed 0.75% per annum of the average daily net assets attributable to ILA Class
B and Class C Units, respectively, of the ILA Prime Obligations Portfolio.

      Under the Distribution and Service Plans for ILA Class B and Class C
Shares, Goldman Sachs is also entitled to receive a separate fee for personal
and account maintenance services equal to an annual basis of 0.25% of each
Fund's average daily net assets attributable to ILA Class B or Class C Units.

      The Distribution and Service Plans are compensation plans which provide
for the payment of a specified fee without regard to the expenses actually
incurred by Goldman Sachs. The distribution fees received by Goldman Sachs under
the Distribution and Service Plans and contingent deferred sales charges on ILA
Class B Units may be sold by Goldman Sachs as distributor to entities which
provide financing for payments to Authorized Dealers in respect of sales of ILA
Class B Units. Goldman Sachs may also pay up to the entire amount of its fee
under the Class C Distribution and Service Plan to Service Organizations or
other institutions for providing services in connection with the sale of Class C
Units. To the extent such fees are not paid to such dealers, Goldman Sachs may
retain such fee as compensation for its services and expenses of distributing
ILA Class B Units and Class C Units. If such fees exceed Goldman Sachs'
expenses, Goldman Sachs may realize a profit from these arrangements.

      For the fiscal year ended December 31, 1998, the amount of distribution
and service fees paid by the ILA Prime Obligation Portfolio's Class B Shares to
Goldman Sachs was $59,917. For the fiscal year ended December 31, 1998, the
amount of distribution and service fees paid by the ILA Prime Obligations
Portfolio's Class C Shares to Goldman Sachs was $43,200.


                                     -101-
<PAGE>
 
      For the fiscal year ended December 31, 1997, the amount of distribution
fees paid by the ILA Prime Obligations Portfolio's Class B Shares to Goldman
Sachs was $4,635. For the fiscal year ended December 31, 1997, the amount of
services fees paid by the ILA Prime Obligations Portfolio's Class B Shares to
Goldman Sachs was $1,545.

      For the fiscal year ended December 31, 1997, the amount of distribution
fees paid by the ILA Prime Obligations Portfolio's Class C Shares to Goldman
Sachs was $784. For the fiscal year ended December 31, 1997, the amount of
service fees paid by the ILA Prime Obligations Portfolio's Class C Shares to
Goldman Sachs was $261.

      During the fiscal year ended December 31, 1998, Goldman Sachs incurred the
following expenses in connection with distribution activities under the
Distribution and Service Plan of the ILA Prime Obligations Portfolio with
respect to ILA Class B Units and ILA Class C Units, respectively: compensation
to dealers, $35,929 and $18,147; compensation and expenses of the Distributor
and its sales personnel, $1,324 and $511; allocable overhead, telephone and
travel expenses, $1,061 and $409; printing and mailing of prospectuses to other
than current unit holders, $69 and $27; and preparation and distribution of
sales literature and advertising, $245 and $95. These amounts reflect expenses
incurred by Goldman Sachs, which amounts are in excess of the compensation
received by Goldman Sachs under the Distribution and Service Plan. The payments
under the Distribution and Service Plan were used by Goldman Sachs to compensate
it for the expenses shown above on a pro-rata basis. Compensation to dealers
includes advance commissions paid to dealers of 4% on ILA Class B Units and 1%
on ILA Class C Units which are considered deferred assets and amortized over a
period of 6 years with respect to ILA Class B units and 1 year with respect to
ILA Class C Units. The amounts presented above reflect amortization expense
recorded during the period presented.

      The Distribution and Service Plans will remain in effect from year to
year, provided such continuance is approved annually by a majority vote of the
Trustees of the Trust, including a majority of the non-interested Trustees who
have no direct or indirect financial interest in the Distribution and Service
Plans. The Distribution and Service Plans may not be amended to increase
materially the amount of distribution compensation described therein as to a
particular Portfolio without approval of a majority of the outstanding Class B
or Class C Unitholders, of the affected Portfolio and Unit class. All material
amendments to the Distribution and Service Plans must also be approved by the
Trustees of the Trust in the manner described above. The Distribution and
Service Plans may be terminated at any time without payment of any penalty by a
vote of the majority of the non-interested Trustees or by vote of a majority of
the Class B or Class C Units, of the applicable Portfolio. If the Distribution
and Service Plans were terminated by the Trust's Board of Trustees and no
successor plan were adopted, the Portfolios would cease to make distribution
payments to Goldman Sachs and Goldman Sachs would be unable to recover the
amount of any of its unreimbursed distribution expenditures. So long as the
Distribution and Service Plans are in effect, the selection and nomination of
non-interested Trustees will be committed to the discretion of the
non-interested Trustees. The Trustees have determined that in their judgment
there is a reasonable likelihood that the Distribution and Service Plans will
benefit the applicable Portfolios and their respective Unitholders.

      Distribution Plan. As described in the Prospectus, the Trust has adopted a
distribution plan pursuant to Rule 12b-1 under the Act with respect to Cash
Management Shares on behalf of the ILA Prime Obligations Portfolio, ILA Money
Market Portfolio, ILA Government Portfolio, ILA Tax-Exempt Diversified
Portfolio, ILA Tax-Exempt California Portfolio and ILA Tax-Exempt New York
Portfolio (the "Cash Management Shares Distribution Plan").

      The Distribution Plan was most recently approved on April 27, 1999 on
behalf of the Trust by a majority vote of the Trust's Board of Trustees,
including a majority of the Trustees who are not interested persons of the Trust
and have no direct or indirect financial interest in the Distribution Plan, cast
in person at a meeting called for the purpose of approving the Distribution
Plan.

      The compensation payable under the Cash Management Shares Distribution
Plan with respect to the ILA Prime Obligations Portfolio, ILA Money Market
Portfolio, ILA Government Portfolio, ILA Tax-Exempt Diversified Portfolio, ILA
Tax-Exempt California Portfolio and ILA Tax-Exempt New York Portfolio may not
exceed 0.50% per annum of the average daily net assets attributable to Cash
Management Shares of such ILA Portfolio. Goldman Sachs may modify or discontinue
such waivers and limitation in the future at its discretion.

      For the fiscal year ended December 31, 1998, the amount of distribution
fees paid by the ILA Prime Obligations Portfolio, ILA Money Market Portfolio,
ILA Government Portfolio, ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt
California Portfolio and ILA Tax-Exempt New York Portfolio to Goldman Sachs
pursuant to the Cash Management Shares Distribution Plan was $0, $0, $0, $0, $0
and $0, respectively.

      Goldman Sachs may pay up to the entire amount of its fee under the
Distribution Plan to Service Organizations or other institutions for providing
services in connection with the sale of Cash Management Shares. To the extent
such fees are not paid to such dealers, Goldman Sachs may retain such fee as
compensation for its services and expenses of distributing Cash Management
Shares. If such fee exceeds its expenses, Goldman Sachs may realize a profit
from these arrangements.

      The Distribution Plan is a compensation plan which provides for the
payment of a specified distribution fee without regard to the distribution
expenses actually incurred by Goldman Sachs. If the Distribution Plan was
terminated by the Trust's Board of Trustees and no successor plan were adopted,
the ILA Prime Obligations Portfolio, ILA Money Market Portfolio, ILA Government
Portfolio, ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio and ILA Tax-Exempt New York Portfolio would cease to make distribution
payments to Goldman Sachs and Goldman Sachs would be unable to recover the
amount of any of its unreimbursed distribution expenditures. However, Goldman
Sachs does not intend to make expenditures for which it may be compensated under
the Cash Management Shares Distribution Plan at a rate that materially exceeds
the rate of compensation received under the Plan.

      The Distribution Plan will remain in effect from year to year, provided
such continuance is approved annually by a majority vote of the Board of
Trustees of the Trust, including a majority of the non-interested Trustees who
have no direct or indirect financial interest in the Distribution Plan. The
Distribution Plan may not be amended to increase materially the amount to be
spent for the services described therein as to a particular Portfolio without
approval of a majority of the outstanding Cash Management Unitholders, as
applicable, of that Portfolio. All material amendments to the Distribution Plan
must also be approved by the Board of Trustees of the Trust in the manner
described above. The Distribution Plans may be terminated at any time without
payment of any penalty by a vote of the majority of the non-interested Trustees
or by vote of a majority of the Cash Management Units, as applicable, of the
applicable Portfolio. So long as the Distribution Plan is in effect, the
selection and nomination of non-interested Trustees shall be committed to the
discretion of the non-interested Trustees. The Trustees have determined that in
their judgment there is a reasonable likelihood that the Distribution Plan will
benefit the applicable Portfolios and their respective Unitholders.

Short-Term Debt Credit Ratings

            A Standard & Poor's short-term issue credit rating is generally a
current assessment of the likelihood of timely payment of debt having an
original maturity of no more than 365 days. The following summarizes the rating
categories used by Standard and Poor's for short-term debt:

            "A-1" - The highest category indicating that the obligor's capacity
to meet its financial commitment on the obligation is strong. Within this
category, certain obligations are designated with a plus sign (+). This
indicates that the obligor's capacity to meet its financial commitment on these
obligations is extremely strong.

            "A-2" - Obligations are somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

            Moody's short-term debt ratings are opinions of the ability of
issuers to repay punctually senior debt obligations not having an original
maturity in excess of one year, unless explicitly noted. The following
summarizes the rating categories used by Moody's for commercial short-term debt:

            "Prime-1" - Issuers (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:
leading market positions in well-established industries; high rates of return on
funds employed; conservative capitalization structure with moderate reliance on
debt and ample asset protection; broad margins in earnings coverage of fixed
financial charges and high internal cash generation; and well-established access
to a range of financial markets and assured sources of alternate liquidity.

            "Prime-2" - Issuers (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

            Duff & Phelps short-term credit ratings apply to obligations with
maturities of under one year and are consistent with the rating criteria used by
money market participants. Duff & Phelps employs three designations, "D-1+,"
"D-1" and "D-1-," within the highest rating category. The following summarizes
the rating categories used by Duff & Phelps for short-term debt:


                                      A-1
<PAGE>
 
            "D-1+" - Debt possesses the highest certainty of timely payment.
Short-term liquidity, including internal operating factors and/or access to
alternative sources of funds, is outstanding, and safety is just below risk-free
U.S. Treasury short-term obligations.

            "D-1" - Debt possesses very high certainty of timely payment.
Liquidity factors are excellent and supported by good fundamental protection
factors. Risk factors are minor.

            "D-1-" - Debt possesses high certainty of timely payment. Liquidity
factors are strong and supported by good fundamental protection factors. Risk
factors are very small.

            "D-2" - Debt possesses good certainty of timely payment. Liquidity
factors and company fundamentals are sound. Although ongoing funding needs may
enlarge total financing requirements, access to capital markets is good. Risk
factors are small.

            Fitch IBCA short-term ratings apply to debt obligations that have a
time horizon of less than 12 months for most obligations, or up to three years
for U.S. public finance securities. The following summarizes the rating
categories used by Fitch IBCA for short-term obligations:

            "F1" - The highest credit quality. This designation indicates the
strongest capacity for timely payment of financial commitments and may have an
added "+" to denote any exceptionally strong credit feature.

            "F2" - Good credit quality. This designation indicates a
satisfactory capacity for timely payment of financial commitments, but the
margin of safety is not as great as in the case of the higher ratings.

            Thomson Financial BankWatch short-term ratings assess the likelihood
of an untimely or incomplete payment of principal and interest of debt
instruments with original maturities of one year or less. The following
summarizes the ratings used by Thomson Financial BankWatch:

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

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

Corporate and Municipal Long-Term Debt Ratings

            The following summarizes the ratings used by Standard & Poor's for
corporate and municipal long-term debt (ratings from "AA" through "BBB" may be
modified by the addition of a plus (+) or minus (-) sign to show relative
standing within the major rating categories):

            "AAA" - An obligation rated "AAA" has the highest rating assigned by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is extremely strong.

            "AA" - An obligation rated "AA" differs from the highest rated
obligations only in small degree. The obligor's capacity to meet its financial
commitment on the obligation is very strong.

            "A" - An obligation rated "A" is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher-rated categories. However, the obligor's capacity to meet
its financial commitment on the obligation is still strong.

            "BBB" - An obligation rated "BBB" exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

      The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt (Numerical modifiers 1, 2 and 3 are applied in each
generic rating classification from "Aa" through "Baa". The modifier indicates
that the obligations ranks in the higher end of its generic rating category; the
modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking
in the lower end of its generic rating category):

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

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

            "A" - Bonds 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.


                                      A-3
<PAGE>
 
            "Baa" - Bonds 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.

            The following summarizes the long-term debt ratings used by Duff &
Phelps for corporate and municipal long-term debt (The "AA," "A," and "BBB",
ratings may be modified by the addition of a plus (+) or minus (-) sign to show
relative standing within these major categories):

            "AAA" - Debt is considered to be of the highest credit quality. The
risk factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

            "AA" - Debt is considered to be of high credit quality. Protection
factors are strong. Risk is modest but may vary slightly from time to time
because of economic conditions.

            "A" - Debt possesses protection factors which are average but
adequate. However, risk factors are more variable in periods of greater economic
stress.

            "BBB" - Debt possesses below-average protection factors but such
protection factors are still considered sufficient for prudent investment.
Considerable variability in risk is present during economic cycles.

            The following summarizes the ratings used by Fitch IBCA for
corporate and municipal long-term debt (Ratings from and including "AA" to "BBB"
may be modified by the addition of a plus (+) or minus (-) sign to show relative
standing within these major categories):

            "AAA" - Highest credit quality. These ratings denote the lowest
expectation of credit risk and are assigned only in case of exceptionally strong
capacity for timely payment of financial commitments. This capacity is highly
unlikely to be adversely affected by foreseeable events.

            "AA" - Very high credit quality. These ratings denote a very low
expectation of credit risk and indicate very strong capacity for timely payment
of financial commitments. This capacity is not significantly vulnerable to
foreseeable events.

            "A" - High credit quality. These ratings denote a low expectation of
credit risk and indicate strong capacity for timely payment of financial
commitments. This capacity may, nevertheless, be more vulnerable to changes in
circumstances or in economic conditions than is the case for higher ratings.

            "BBB" - Good credit quality. These ratings denote that there is
currently a low expectation of credit risk. The capacity for timely payment of
financial commitments is 


                                      A-4
<PAGE>
 
considered adequate, but adverse changes in circumstances and in economic
conditions are more likely to impair this capacity.

            The following summarizes the rating categories used by Thomson
Financial BankWatch for long-term debt ratings (The ratings may include a plus
(+) or minus (-) sign designation which indicates where, within the respective
category the issue is placed):

            "AAA" - This designation indicates that the ability to repay
principal and interest on a timely basis is extremely high.

            "AA" - This designation indicates a very strong ability to repay
principal and interest on a timely basis, with limited incremental risk compared
to issues rated in the highest category.

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

            "BBB" - This designation represents the lowest investment-grade
category and indicates an acceptable capacity to repay principal and interest.
Issues rated "BBB" are more vulnerable to adverse developments (both internal
and external) than obligations with higher ratings.

Additional Municipal Note Ratings

            A Standard and Poor's rating reflects the liquidity concerns and
market access risks unique to notes due in three years or less. The following
summarizes the ratings used by Standard & Poor's Ratings Group for municipal
notes:

            "SP-1" - The issuers of these municipal notes exhibit a strong
capacity to pay principal and interest. Those issues determined to possess very
strong characteristics are given a plus (+) designation.

            "SP-2" - The issuers of these municipal notes exhibit satisfactory
capacity to pay principal and interest, with some vulnerability to adverse
financial and economic changes over the term of the notes.

            Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade ("VMIG"). Such
ratings recognize the differences between short-term credit risk and long-term
risk. The following summarizes the ratings by Moody's Investors Service, Inc.
for short-term notes:


                                      A-5
<PAGE>
 
            "MIG-1"/"VMIG-1" - This designation denotes best quality. There is
present strong protection by established cash flows, superior liquidity support
or demonstrated broad-based access to the market for refinancing.

            "MIG-2"/"VMIG-2" - This designation denotes high quality, with
margins of protection that are ample although not so large as in the preceding
group.

            "MIG-3"/"VMIG-3" - This designation denotes favorable quality, with
all security elements accounted for but lacking the undeniable strength of the
preceding grades. Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.

            Fitch IBCA and Duff & Phelps use the short-term ratings described
under Short-Term Debt Credit Ratings for municipal notes.

                   BUSINESS PRINCIPLES OF GOLDMAN, SACHS & CO.

      Goldman Sachs is noted for its Business Principles, which guide all of the
firm's activities and serve as the basis for its distinguished reputation among
investors worldwide.

      Our client's interests always come first. Our experience shows that if we
serve our clients well, our own success will follow.

      Our assets are our people, capital and reputation.  If any of these is 
ever diminished, the last is the most difficult to restore.  We are dedicated to
complying fully with the letter and spirit of the laws, rules and ethical 
principles that govern us.  Our continued success depends upon unswerving 
adherence to this standard.

      We take great pride in the professional quality of our work. We have an
uncompromising determination to achieve excellence in everything we undertake.
Though we may be involved in a wide variety and heavy volume of activity, we
would, if it came to a choice, rather be best than biggest.

      We stress creativity and imagination in everything we do. While
recognizing that the old way may still be the best way, we constantly strive to
find a better solution to a client's problems. We pride ourselves on having
pioneered many of the practices and techniques that have become standard in the
industry.

      We make an unusual effort to identify and recruit the very best person for
every job.  Although our activities are measured in billions of dollars, we 
select our people one by one.  In a service business, we know that without the 
best people, we cannot be the best firm.

      We offer our people the opportunity to move ahead more rapidly than is 
possible at most other places.  We have yet to find the limits to the 
responsibility that our best people are able to assume.  Advancement depends 
solely on ability, performance and contribution to the firm's success, without
regard to race, color, religion, sex, age, national origin, disability, sexual 
orientation, or any other impermissible criterion or circumstance.

      We stress teamwork in everything we do.  While individual creativity is 
always encouraged, we have found that team effort often produces the best 
results.  We have no room for those who put their personal interests ahead of 
the interests of the firm and its clients.

      The dedication of our people to the firm and the intense effort they give 
their jobs are greater than one finds in most other organizations.  We think 
that this is an important part of our success.

      Our profits are a key to our success.  They replenish our capital and 
attract and keep our best people.  It is our practice to share our profits 
generously with all who helped create them.  Profitability is crucial to our 
future.

      We consider our size an asset that we try hard to preserve.  We want to be
big enough to undertake the largest project that any of our clients could 
contemplate, yet small enough to maintain the loyalty, the intimacy and the 
esprit de corps that we all treasure and that contribute greatly to our success.

      We constantly strive to anticipate the rapidly changing needs of our 
clients and to develop new services to meet those needs.  We know that the world
of finance will not stand still and that complacency can lead to extinction.

      We regularly receive confidential information as part of our normal client
relationships.  To breach a confidence or to use confidential information 
improperly or carelessly would be unthinkable.

      Our business is highly competitive, and we aggressively seek to expand our
client relationships.  However, we must always be fair competitors and must 
never denigrate other firms.

      Integrity and honesty are the heart of our business. We expect our people

                                  INTRODUCTION

      Goldman Sachs Trust (the "Trust") is an open-end, management investment
company. The Trust is organized as a Delaware business trust, and is a successor
to a Massachusetts business trust that was combined with the Trust on April 30,
1997. The following series of the Trust are described in this Additional
Statement: Goldman Sachs Balanced Fund ("Balanced Fund"), Goldman Sachs Growth
and Income Fund ("Growth and Income Fund"), Goldman Sachs CORE Large Cap Value
Fund ("CORE Large Cap Value Fund"), Goldman Sachs CORE U.S. Equity Fund ("CORE
U.S. Equity Fund") (formerly known as "Goldman Sachs Select Equity Fund"),
Goldman Sachs CORE Large Cap Growth Fund ("CORE Large Cap Growth Fund"), Goldman
Sachs CORE Small Cap Equity Fund ("CORE Small Cap Equity Fund"), Goldman Sachs
CORE International Equity Fund ("CORE International Equity Fund"), Goldman Sachs
Capital Growth Fund ("Capital Growth Fund"), Goldman Sachs Strategic Growth Fund
("Strategic Growth Fund"), Goldman Sachs Growth Opportunities Fund ("Growth
Opportunities Fund"), Goldman Sachs Mid Cap Value Fund ("Mid Cap Value Fund"),
Goldman Sachs International Equity Fund ("International Equity Fund"), Goldman
Sachs Small Cap Value Fund ("Small Cap Value Fund"), Goldman Sachs European
Equity Fund ("European Equity Fund"), Goldman Sachs Japanese Equity Fund
("Japanese Equity Fund"), Goldman Sachs International Small Cap Fund
("International Small Cap Fund"), Goldman Sachs Emerging Markets Equity Fund
("Emerging Markets Equity Fund"), Goldman Sachs Asia Growth Fund ("Asia Growth
Fund") and Goldman Sachs Real Estate Securities Fund ("Real Estate Securities
Fund") (collectively referred to herein as the "Funds"). As of the date of this 
Additional Statement, no shares of the Strategic Growth or Growth Opportunities
Funds had been offered.

      The Funds, except the European Equity, Japanese Equity, International
Small Cap, CORE Large Cap Value, CORE Large Cap Growth, CORE International
Equity, Strategic Growth Fund, Growth Opportunities Fund, CORE Small Cap Equity
and Real Estate Securities Funds, were initially organized as a series of a
corporation formed under the laws of the State of Maryland on September 27, 1989
and were reorganized as a Delaware business trust as of April 30, 1997. The
Trustees have authority under the Trust's charter to create and classify shares
into separate series and to classify and reclassify any series or portfolio of
shares into one or more classes without further action by shareholders. Pursuant
thereto, the Trustees have created the Funds and other series. Additional series
may be added in the future from time to time. Each Fund currently offers five
classes of shares: Class A Shares, Class B Shares, Class C Shares, Institutional
Shares and Service Shares. See "Shares of the Trust."

      Goldman Sachs Asset Management, ("GSAM") a separate operating division of
Goldman, Sachs & Co. ("Goldman Sachs"), serves as the Investment Adviser to the
Balanced, Growth and Income, CORE Large Cap Value, CORE Large Cap Growth, CORE
Small Cap Equity, Strategic Growth, Growth Opportunities, CORE International
Equity, Mid Cap Value, Small Cap Equity and Real Estate Securities Funds.
Goldman Sachs Funds Management, L.P. ("GSFM"), an affiliate of Goldman Sachs,
serves as the Investment Adviser to the CORE U.S. Equity and Capital Growth
Funds. Goldman Sachs Asset Management International ("GSAMI"), an affiliate of
Goldman Sachs, serves as the Investment Adviser to the International Equity,
European Equity, Japanese Equity, International Small Cap, Emerging Markets
Equity and Asia Growth Funds. GSAM, GSFM and GSAMI are sometimes referred to
collectively herein as the "Investment Advisers." In addition, Goldman Sachs
serves as each Fund's distributor and transfer agent. Each Fund's custodian is
State Street Bank and Trust Company ("State Street").

      The following information relates to and supplements the description of
each Fund's investment policies contained in the Prospectuses. See the
Prospectuses for a fuller description of the Funds' investment objectives and
policies. There is no assurance that a Fund will achieve its objective.

                               INVESTMENT POLICIES

      Each Fund has distinct investment objectives and policies. There can be no
assurance that a Fund's objectives will be achieved. Each Fund is a diversified
open-end management company as defined in the Investment Company Act of 1940, as
amended (the "Act").

      Each Fund's share price will fluctuate with market, economic and, to the
extent applicable, foreign exchange conditions, so that an investment in any of
the Funds may be worth more or less when redeemed than when purchased. None of
the Funds should be relied upon as a complete investment program.

General Information Regarding All Funds.

      The Investment Adviser may purchase for the Funds common stocks, preferred
stocks, interests in real estate investment trusts, convertible debt
obligations, convertible preferred stocks, equity interests in trusts,
partnerships, joint ventures, limited liability companies and similar
enterprises, warrants and stock purchase rights ("equity securities"). In
choosing a Fund's securities, the Investment Adviser utilizes first-hand
fundamental research, including visiting company facilities to assess operations
and to meet decision-makers. The Investment Adviser may also use macro analysis
of numerous economic and valuation variables to anticipate changes in company
earnings and the overall investment climate. The Investment Adviser is able to
draw on the research and market expertise of the Goldman Sachs Global Investment
Research Department and other affiliates of the Investment Adviser, as well as
information provided by other securities dealers. Equity securities in a Fund's
portfolio will generally be sold when the Investment Adviser believes that the
market price fully reflects or exceeds the securities' fundamental valuation or
when other more attractive investments are identified.

      Value Style Funds. The Growth and Income Fund, Mid Cap Value Fund, Small
Cap Value Fund and a portion of the equity portion of Balanced Fund are managed
using a value oriented approach. (The equity portion of the Balanced Fund
utilizes a blend of value and growth investment styles. See "Growth Style Funds"
below). The Investment Adviser evaluates securities using fundamental analysis
and intends to purchase equity securities that are, in its view, underpriced
relative to a combination of such companies' long-term earnings prospects,
growth rate, free cash flow and/or dividend-paying ability. Consideration will
be given to the business quality of the issuer. Factors positively affecting the
Investment Adviser's view of that quality include the competitiveness and degree
of regulation in the markets in which the company operates, the existence of a
management team with a record of success, the position of the company in the
markets in which it operates, the level of the company's financial leverage and
the sustainable return on capital invested in the business. The Funds may also
purchase securities of companies that have experienced difficulties and that, in
the opinion of the Investment Adviser, are available at attractive prices.

      Growth Style Funds. The Capital Growth, Strategic Growth and Growth
Opportunities Funds and a portion of the equity portion of the Balanced Fund are
managed using a growth equity oriented approach. Equity securities for these
Funds are selected based on their prospects for above average growth. The
Investment Adviser will select securities of growth companies trading, in the
Investment Adviser's opinion, at a reasonable price relative to other
industries, competitors and


                                      B-7
<PAGE>
 
historical price/earnings multiples. The Funds will generally invest in
companies whose earnings are believed to be in a relatively strong growth trend,
or, to a lesser extent, in companies in which significant further growth is not
anticipated but whose market value per share is thought to be undervalued. In
order to determine whether a security has favorable growth prospects, the
Investment Adviser ordinarily looks for one or more of the following
characteristics in relation to the security's prevailing price: prospects for
above average sales and earnings growth per share; high return on invested
capital; free cash flow generation; sound balance sheet, financial and
accounting policies, and overall financial strength; strong competitive
advantages; effective research, product development, and marketing; pricing
flexibility; strength of management; and general operating characteristics that
will enable the company to compete successfully in its marketplace.

      Quantitative Style Funds. CORE U.S. Equity, CORE Large Cap Growth, CORE
Large Cap Value, CORE Small Cap Equity and CORE International Equity Funds (the
"CORE Equity Funds") are managed using both quantitative and fundamental
techniques. CORE is an acronym for "Computer-Optimized, Research-Enhanced,"
which reflects the CORE Funds' investment process. This investment process and
the proprietary multifactor model used to implement it are discussed below.

      Investment Process. The Investment Adviser begins with a broad universe of
U.S. equity securities for CORE U.S. Equity, CORE Large Cap Growth, CORE Large
Cap Value and CORE Small Cap Equity Funds (the "CORE U.S. Equity Funds"), and a
broad universe of foreign equity securities for CORE International Equity Fund.
As described more fully below, the Investment Adviser uses a proprietary
multifactor model (the "Multifactor Model") to forecast the returns of different
markets, currencies and individual securities. In the case of an equity security
followed by the Goldman Sachs Global Investment Research Department (the
"Research Department"), a rating is assigned based upon the Research
Department's evaluation. In the discretion of the Investment Adviser, ratings
may also be assigned to equity securities based on research ratings obtained
from other industry sources.

      In building a diversified portfolio for each CORE Equity Fund, the
Investment Adviser utilizes optimization techniques to seek to maximize the
Fund's expected return, while maintaining a risk profile similar to the Fund's
benchmark. Each portfolio is primarily composed of securities rated highest by
the foregoing investment process and has risk characteristics and industry
weightings similar to the relevant Fund's benchmark.

      Multifactor Models. The Multifactor Models are rigorous computerized
rating systems for forecasting the returns of different equity markets,
currencies and individual equity securities according to fundamental investment
characteristics. The CORE U.S. Funds use one Multifactor Model to forecast the
returns of securities held in each Fund's portfolio. CORE International Equity
Fund uses multiple Multifactor Models to forecast returns. Currently, CORE
International Equity Fund uses one model to forecast equity market returns, one
model to forecast currency returns and 22 separate models to forecast individual
equity security returns in 22 different countries. Despite this variety, all
Multifactor Models incorporate common variables covering measures of value,
growth, momentum and risk (e.g., book/price ratio, earnings/price ratio, price
momentum, price volatility, consensus growth forecasts, earnings estimate
revisions, earnings stability, and, in the case of models for CORE International
Equity Fund, currency momentum and country political risk


                                      B-8
<PAGE>
 
ratings). All of the factors used in the Multifactor Models have been shown to
significantly impact the performance of the securities, currencies and markets
they were designed to forecast.

      The weightings assigned to the factors in the Multifactor Model used by
the CORE U.S. Funds are derived using a statistical formulation that considers
each factor's historical performance in different market environments. As such,
the U.S. Multifactor Model is designed to evaluate each security using only the
factors that are statistically related to returns in the anticipated market
environment. Because they include many disparate factors, the Investment Adviser
believes that all the Multifactor Models are broader in scope and provide a more
thorough evaluation than most conventional quantitative models. Securities and
markets ranked highest by the relevant Multifactor Model do not have one
dominant investment characteristic; rather, they possess an attractive
combination of investment characteristics. By using a variety of relevant
factors to select securities, currencies or markets, the Investment Adviser
believes that the Fund will be better balanced and have more consistent
performance than an investment portfolio that uses only one or two factors to
select such investments.

      The Investment Adviser will monitor, and may occasionally suggest and make
changes to, the method by which securities, currencies or markets are selected
for or weighted in a Fund. Such changes (which may be the result of changes in
the Multifactor Models or the method of applying the Multifactor Models) may
include: (i) evolutionary changes to the structure of the Multifactor Models
(e.g., the addition of new factors or a new means of weighting the factors);
(ii) changes in trading procedures (e.g., trading frequency or the manner in
which a Fund uses futures); or (iii) changes in the method by which securities,
currencies or markets are weighted in a Fund. Any such changes will preserve a
Fund's basic investment philosophy of combining qualitative and quantitative
methods of selecting securities using a disciplined investment process.

      Research Department. In assigning ratings to equity securities, the
Research Department uses a four category rating system ranging from "recommended
for purchase" to "likely to under perform." The ratings reflect the analyst's
judgment as to the investment results of a specific security and incorporate
economic outlook, valuation, risk and a variety of other factors.

      By employing both a quantitative (i.e., the Multifactor Models) and a
qualitative (i.e., research enhanced) method of selecting securities, each CORE
Equity Fund seeks to capitalize on the strengths of each discipline.

      Other Information. Since normal settlement for equity securities is three
trading days (for certain international markets settlement may be longer), the
Funds will need to hold cash balances to satisfy shareholder redemption
requests. Such cash balances will normally range from 2% to 5% of a Fund's net
assets. CORE U.S. Equity Fund may enter into futures transactions only with
respect to the S&P 500 Index and the CORE Large Cap Growth, CORE Large Cap Value
and CORE Small Cap Equity Funds may enter into futures transactions only with
respect to a representative index in order to keep a Fund's effective equity
exposure close to 100%. CORE Small Cap Equity and CORE International Equity
Funds may purchase other types of futures contracts. For example, if cash
balances are equal to 5% of the net assets, the Fund may enter into long futures
contracts covering an amount equal to 5% of the Fund's net


                                      B-9
<PAGE>
 
assets. As cash balances fluctuate based on new contributions or withdrawals, a
Fund may enter into additional contracts or close out existing positions.

      Actively Managed International Funds. The International Equity, Japanese
Equity, European Equity, International Small Cap, Emerging Markets Equity and
Asia Growth Funds are managed using an active international approach, which
utilizes a consistent process of stock selection undertaken by portfolio
management teams located within each of the major investment regions, including
Europe, Japan, Asia and the United States. In selecting securities, the
Investment Adviser uses a long-term, bottom-up strategy based on first-hand
fundamental research that is designed to give broad exposure to the available
opportunities while seeking to add return primarily through stock selection.
Equity securities for these Funds are evaluated based on three key factors--the
business, the management and the valuation. The Investment Adviser ordinarily
seeks securities that have, in the investment adviser's opinion, superior
earnings growth potential, sustainable franchise value with management attuned
to creating shareholder value and relatively discounted valuations. In addition,
the investment adviser uses a multi-factor risk model which seeks to assure that
deviations from the benchmark are justifiable.

      Real Estate Securities Fund. The investment strategy of the Real Estate
Securities Fund is based on the premise that property market fundamentals are
the primary determinant of growth underlying the success of companies in the
real estate industry. The Fund's research and investment process focuses on
companies that can achieve sustainable growth in cash flow and dividend paying
capability. This process is comprised of real estate market research and
securities analysis. The Fund's Investment Adviser will take into account
fundamental trends in underlying property markets as determined by proprietary
models, research of local real estate market, earnings, cash flow growth and
stability, the relationship between asset values and market prices of the
securities and dividend payment history. The Investment Adviser will attempt to
purchase securities so that its underlying portfolio will be diversified
geographically and by property type.

Additional Information About Balanced Fund

      The investment objective of the Balanced Fund is to provide long-term
growth of capital and current income. The Fund seeks growth of capital primarily
through investments in equity securities (stocks). The Fund seeks to provide
current income through investment in fixed-income securities.

      Balanced Fund is intended to provide a foundation on which an investor can
build an investment portfolio or to serve as the core of an investment program,
depending on the investor's goals. Balanced Fund is designed for relatively
conservative investors who seek a combination of long-term capital growth and
current income in a single investment. Balanced Fund offers a portfolio of
equity and fixed-income securities intended to provide less volatility than a
portfolio completely invested in equity securities and greater diversification
than a portfolio invested in only one asset class. Balanced Fund may be
appropriate for people who seek capital appreciation but are concerned about the
volatility typically associated with a fund that invests solely in stocks and
other equity securities.

      Fixed-Income Strategies Designed to Maximize Return and Manage Risk.
GSAM's approach to managing the fixed-income portion of Balanced Fund's
portfolio seeks to provide high


                                      B-10
<PAGE>
 
returns relative to a market benchmark, the Lehman Brothers Aggregate Bond Index
(the "Index"), while also seeking to provide high current income. This approach
emphasizes (1) sector allocation strategies which enable GSAM to tactically
overweight or underweight one sector of the fixed-income market (i.e.,
mortgages, corporate bonds, U.S. Treasuries, non-dollar bonds, emerging market
debt) versus another; (2) individual security selection based on identifying
relative value (fixed-income securities inexpensive relative to others in their
sector); and (3) to a lesser extent, strategies based on GSAM's expectation of
the direction of interest rates or the spread between short-term and long-term
interest rates such as yield curve strategy.

      The Index currently includes U.S. Government Securities and fixed-rate,
publicly issued, U.S. dollar-denominated fixed income securities rated at least
BBB or Baa by a nationally recognized statistical ratings organization
("NRSRO"). The securities currently included in the Index have at least one year
remaining to maturity; have an outstanding principal amount of at least $100
million; and are issued by the following types of issuers, with each category
receiving a different weighting in the Index: U.S. Treasury; agencies,
authorities or instrumentalities of the U.S. government; issuers of
mortgage-backed securities; utilities; industrial issuers; financial
institutions; foreign issuers; and issuers of asset-backed securities. The Index
is a trademark of Lehman Brothers. Inclusion of a security in the Index does not
imply an opinion by Lehman Brothers as to its attractiveness or appropriateness
for investment. Although Lehman Brothers obtains factual information used in
connection with the Index from sources which it considers reliable, Lehman
Brothers claims no responsibility for the accuracy, completeness or timeliness
or such information and has no liability to any person for any loss arising from
results obtained from the use of the Index data.

      GSAM seeks to manage fixed-income portfolio risk in a number of ways.
These include diversifying the fixed-income portion of the Balanced Fund's
portfolio among various types of fixed-income securities and utilizing
sophisticated quantitative models to understand how the fixed-income portion of
the portfolio will perform under a variety of market and economic scenarios. In
addition, GSAM uses extensive credit analysis to select and to monitor any
investment-grade or non-investment grade bonds that may be included in the
Balanced Fund's portfolio. In employing this and other investment strategies,
the GSAM team has access to extensive fundamental research and analysis
available through Goldman Sachs and a broad range of other sources.

      A number of investment strategies will be used in selecting fixed-income
securities for the Fund's portfolio. GSAM's fixed-income investment philosophy
is to actively manage the portfolio within a risk-controlled framework. The
Investment Adviser de-emphasizes interest rate anticipation by monitoring the
duration of the portfolio within a narrow range of the Investment Adviser's
target duration, and instead focuses on seeking to add value through sector
selection, security selection and yield curve strategies.

      Market Sector Selection. Market sector selection is the underweighting or
overweighting of one or more market sectors (i.e., U.S. Treasuries, U.S.
Government agency securities, corporate securities, mortgage-backed securities
and asset-backed securities). GSAM may decide to overweight or underweight a
given market sector or subsector (e.g., within the corporate sector,
industrials, financial issuers and utilities) based on, among other things,
expectations of future yield spreads between different sectors or subsectors.


                                      B-11
<PAGE>
 
      Issuer Selection. Issuer selection is the purchase and sale of corporate
securities based on a corporation's current and expected credit standing (within
the constraints imposed by Balanced Fund's minimum credit quality requirements).
This strategy focuses on four types of investment-grade corporate issuers.
Selection of securities from the first type of issuers - those with low but
stable credit - is intended to enhance total returns by providing incremental
yield. Selecting securities from the second type of issuers - those with low and
intermediate but improving credit quality - is intended to enhance total returns
in two stages. Initially, these securities are expected to provide incremental
yield. Eventually, price appreciation should occur relative to alternative
securities as credit quality improves, the NRSROs upgrade credit ratings, and
credit spreads narrow. Securities from the third type of issuers - issuers with
deteriorating credit quality - will be avoided, since total returns are
typically enhanced by avoiding the widening of credit spreads and the consequent
relative price depreciation. Finally, total returns can be enhanced by focusing
on securities that are rated differently by different rating organizations. If
the securities are trading in line with the higher published quality rating
while GSAM concurs with the lower published quality rating, the securities would
generally be sold and any potential price deterioration avoided. On the other
hand, if the securities are trading in line with the lower published quality
rating while the higher published quality rating is considered more realistic,
the securities may be purchased in anticipation of the expected market
reevaluation and relative price appreciation.

      Yield Curve Strategy. Yield curve strategy consists of overweighting or
underweighting different maturity sectors relative to a benchmark to take
advantage of the shape of the yield curve. Three alternative maturity sector
selections are available: a "barbell" strategy in which short and long maturity
sectors are overweighted while intermediate maturity sectors are underweighted;
a "bullet" strategy in which, conversely, short-and long-maturity sectors are
underweighted while intermediate-maturity sectors are overweighted; and a
"neutral yield curve" strategy in which the maturity distribution mirrors that
of a benchmark.

Additional Information About International Equity Fund

      International Equity Fund will seek to achieve its investment objective by
investing primarily in equity securities of companies that are organized outside
the United States or whose securities are principally traded outside the United
States. Because research coverage outside the United States is fragmented and
relatively unsophisticated, many foreign companies that are well-positioned to
grow and prosper have not come to the attention of investors. GSAMI believes
that the high historical returns and less efficient pricing of foreign markets
create favorable conditions for the International Equity Fund's highly focused
investment approach. For a description of the risks of the International Equity
Fund's investments in Asia, see "Investing in Emerging Markets, including Asia
and Eastern Europe."

      A Rigorous Process of Stock Selection. Using fundamental industry and
company research, GSAMI's equity team in London, Singapore and Tokyo seeks to
identify companies that may achieve superior long-term returns. Stocks are
carefully selected for International Equity Fund's portfolio through a
three-stage investment process. Because the International Equity Fund is a
long-term holder of stocks, the portfolio managers adjust the Fund's portfolio
only when expected returns fall below acceptable levels or when the portfolio
managers identify substantially more attractive investments.


                                      B-12

      Using the research of Goldman Sachs as well as information gathered from
other sources in Europe and the Asia-Pacific region, the Investment Adviser
seeks to identify attractive industries around the world. Such industries are
expected to have favorable underlying economics and allow companies to generate
sustainable and predictable high returns. As a rule, they are less economically
sensitive, relatively free of regulation and favor strong franchises.

      Within these industries the Investment Adviser seeks to identify well-run
companies that enjoy a stable competitive advantage and are able to benefit from
the favorable dynamics of the industry. This stage includes analyzing the
current and expected financial performance of the company; contacting suppliers,
customers and competitors; and meeting with management. In particular, the
portfolio managers look for companies whose managers have a strong commitment to
both maintaining the high returns of the existing business and reinvesting the
capital generated at high rates of return. Management should act in the
interests of the owners and seek to maximize returns to all stockholders.

      GSAMI's currency team manages the foreign exchange risk embedded in
foreign equities by means of a currency overlay program. The program may be
utilized to protect the value of foreign investments in sustained periods of
dollar appreciation and to add returns by seeking to take advantage of foreign
exchange fluctuations.

      The members of GSAMI's international equity team bring together years of
experience in analyzing and investing in companies in Europe and the
Asia-Pacific region. Their expertise spans a wide range of skills including
investment analysis, investment management, investment banking and business
consulting. GSAM's worldwide staff of over 300 professionals includes portfolio
managers based in London, Singapore and Tokyo who bring firsthand knowledge of
their local markets and companies to every investment decision.

Corporate Debt Obligations

      Each Fund may, under normal market conditions, invest in corporate debt
obligations, including obligations of industrial, utility and financial issuers.
CORE Large Cap Value, CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap
Equity and CORE International Equity Funds may only invest in debt securities
that are cash equivalents. Corporate debt obligations are subject to the risk of
an issuer's inability to meet principal and interest payments on the obligations
and may also be subject to price volatility due to such factors as market
interest rates, market perception of the creditworthiness of the issuer and
general market liquidity.

      An economic downturn could severely affect the ability of highly leveraged
issuers of junk bond securities to service their debt obligations or to repay
their obligations upon maturity. Factors having an adverse impact on the market
value of junk bonds will have an adverse effect on a Fund's net asset value to
the extent it invests in such securities. In addition, a Fund may incur
additional expenses to the extent it is required to seek recovery upon a default
in payment of principal or interest on its portfolio holdings.

      The secondary market for junk bonds, which is concentrated in relatively
few market makers, may not be as liquid as the secondary market for more highly
rated securities. This reduced liquidity may have an adverse effect on the
ability of Balanced, Growth and Income, Capital


                                      B-13
<PAGE>
 
Growth, Strategic Growth, Growth Opportunities, Mid Cap Value, Small Cap Value,
International Equity, European Equity, Japanese Equity, International Small Cap,
Emerging Markets Equity, Asia Growth and Real Estate Securities Funds to dispose
of a particular security when necessary to meet their redemption requests or
other liquidity needs. Under adverse market or economic conditions, the
secondary market for junk bonds could contract further, independent of any
specific adverse changes in the condition of a particular issuer. As a result,
the Investment Advisers could find it difficult to sell these securities or may
be able to sell the securities only at prices lower than if such securities were
widely traded. Prices realized upon the sale of such lower rated or unrated
securities, under such circumstances, may be less than the prices used in
calculating a Fund's net asset value.

      Since investors generally perceive that there are greater risks associated
with the medium to lower rated securities of the type in which Balanced, Growth
and Income, Capital Growth, Strategic Growth, Growth Opportunities, Mid Cap
Value, Small Cap Value, International Equity, European Equity, Japanese Equity,
International Small Cap, Emerging Markets Equity, Asia Growth and Real Estate
Securities Funds may invest, the yields and prices of such securities may tend
to fluctuate more than those for higher rated securities. In the lower quality
segments of the fixed-income securities market, changes in perceptions of
issuers' creditworthiness tend to occur more frequently and in a more pronounced
manner than do changes in higher quality segments of the fixed-income securities
market, resulting in greater yield and price volatility.

      Another factor which causes fluctuations in the prices of fixed-income
securities is the supply and demand for similarly rated securities. In addition,
the prices of fixed-income securities fluctuate in response to the general level
of interest rates. Fluctuations in the prices of portfolio securities subsequent
to their acquisition will not affect cash income from such securities but will
be reflected in a Fund's net asset value.

      Medium to lower rated and comparable non-rated securities tend to offer
higher yields than higher rated securities with the same maturities because the
historical financial condition of the issuers of such securities may not have
been as strong as that of other issuers. Since medium to lower rated securities
generally involve greater risks of loss of income and principal than higher
rated securities, investors should consider carefully the relative risks
associated with investment in securities which carry medium to lower ratings and
in comparable unrated securities. In addition to the risk of default, there are
the related costs of recovery on defaulted issues. The Investment Advisers will
attempt to reduce these risks through portfolio diversification and by analysis
of each issuer and its ability to make timely payments of income and principal,
as well as broad economic trends and corporate developments.

      The Investment Adviser employs its own credit research and analysis, which
includes a study of existing debt, capital structure, ability to service debt
and to pay dividends, the issuer's sensitivity to economic conditions, its
operating history and the current trend of earnings. The Investment Adviser
continually monitors the investments in a Fund's portfolio and evaluates whether
to dispose of or to retain non-investment grade and comparable unrated
securities whose credit ratings or credit quality may have changed.

U.S. Government Securities

      Each Fund may invest in U.S. Government securities. Generally, these
securities include U.S. Treasury obligations and obligations issued or
guaranteed by U.S. Government agencies, instrumentalities or sponsored
enterprises. U.S. Government Securities also include Treasury receipts and other
stripped U.S. Government securities, where the interest and principal components
of stripped U.S. Government Securities are traded independently. A Fund may also
invest in zero coupon U.S. Treasury securities and in zero coupon securities
issued by financial institutions, which represent a proportionate interest in
underlying U.S. Treasury securities. A zero coupon security pays no interest to
its holder during its life and its value consists of the difference between its
face value at maturity and its cost. The market prices of zero coupon securities
generally are move volatile than the market prices of securities that pay
interest periodically.

Bank Obligations

      Each Fund may invest in obligations issued or guaranteed by U.S. or
foreign banks. Bank obligations, including without limitation, time deposits,
bankers' acceptances and certificates of deposit, may be general obligations of
the parent bank or may be limited to the issuing branch by the terms of the
specific obligations or by government regulation. Banks are subject to extensive
but different governmental regulations which may limit both the amount and types
of loans which may be made and interest rates which may be charged. In addition,
the profitability of the banking industry is largely dependent upon the
availability and cost of funds for the purpose of financing lending operations
under prevailing money market conditions. General economic conditions as well as
exposure to credit losses arising from possible financial difficulties of
borrowers play an important part in the operation of this industry.

Zero Coupon Bonds

      A Fund's investments in fixed-income securities may include zero coupon
bonds, which are debt obligations issued or purchased at a significant discount
from face value. The discount approximates the total amount of interest the
bonds would have accrued and compounded over the period until maturity. Zero
coupon bonds do not require the periodic payment of interest. Such investments
benefit the issuer by mitigating its need for cash to meet debt service but also
require a higher rate of return to attract investors who are willing to defer
receipt of such cash. Such investments may experience greater volatility in
market value than debt obligations which provide for regular payments of
interest. In addition, if an issuer of zero coupon bonds held by a Fund
defaults, the Fund may obtain no return at all on its investment. Each Fund will
accrue income on such investments for each taxable year which (net of deductible
expenses, if any) is distributable to shareholders and which, because no cash is
generally received at the time of accrual, may require the liquidation of other
portfolio securities to obtain sufficient cash to satisfy the Fund's
distribution obligations.

Variable and Floating Rate Securities

      The interest rates payable on certain fixed-income securities in which a
Fund may invest are not fixed and may fluctuate based upon changes in market
rates. A variable rate obligation has an


                                      B-15
<PAGE>
 
interest rate which is adjusted at predesignated periods in response to changes
in the market rate of interest on which the interest rate is based. Variable and
floating rate obligations are less effective than fixed rate instruments at
locking in a particular yield. Nevertheless, such obligations may fluctuate in
value in response to interest rate changes if there is a delay between changes
in market interest rates and the interest reset date for the obligation.

Custodial Receipts

      Each Fund may invest in custodial receipts in respect of securities issued
or guaranteed as to principal and interest by the U.S. Government, its agencies,
instrumentalities, political subdivisions or authorities. Such custodial
receipts evidence ownership of future interest payments, principal payments or
both on certain notes or bonds issued or guaranteed as to principal and interest
by the U.S. Government, its agencies, instrumentalities, political subdivisions
or authorities. These custodial receipts are known by various names, including
"Treasury Receipts," "Treasury Investors Growth Receipts" ("TIGRs"), and
"Certificates of Accrual on Treasury Securities" ("CATs"). For certain
securities law purposes, custodial receipts are not considered U.S. Government
Securities.

Municipal Securities

      Balanced Fund may invest in municipal securities. Municipal securities
consist of bonds, notes and other instruments issued by or on behalf of states,
territories and possessions of the United States (including the District of
Columbia) and their political subdivisions, agencies or instrumentalities, the
interest on which is exempt from regular federal income tax. Municipal
securities are often issued to obtain funds for various public purposes.
Municipal securities also include "private activity bonds" or industrial
development bonds, which are issued by or on behalf of public authorities to
obtain funds for privately operated facilities, such as airports and waste
disposal facilities, and, in some cases, commercial and industrial facilities.

      The yields and market values of municipal securities are determined
primarily by the general level of interest rates, the creditworthiness of the
issuers of municipal securities and economic and political conditions affecting
such issuers. Due to their tax exempt status, the yields and market prices of
municipal securities may be adversely affected by changes in tax rates and
policies, which may have less effect on the market for taxable fixed-income
securities. Moreover, certain types of municipal securities, such as housing
revenue bonds, involve prepayment risks which could affect the yield on such
securities. The credit rating assigned to municipal securities may reflect the
existence of guarantees, letters of credit or other credit enhancement features
available to the issuers or holders of such municipal securities.

      Investments in municipal securities are subject to the risk that the
issuer could default on its obligations. Such a default could result from the
inadequacy of the sources or revenues from which interest and principal payments
are to be made or the assets collateralizing such obligations. Revenue bonds,
including private activity bonds, are backed only by specific assets or revenue
sources and not by the full faith and credit of the governmental issuer.

Mortgage-Backed Securities

      General Characteristics. Each Fund (other than CORE Large Cap Value, CORE
U.S. Equity, CORE Large Cap Growth, CORE Small Cap Equity and CORE International
Equity Funds) may invest in mortgage-backed securities. Each mortgage pool
underlying mortgage-backed securities consists of mortgage loans evidenced by
promissory notes secured by first mortgages or first deeds of trust or other
similar security instruments creating a first lien on owner occupied and
non-owner occupied one-unit to four-unit residential properties, multifamily
(i.e., five or more) properties, agriculture properties, commercial properties
and mixed use properties (the "Mortgaged Properties"). The Mortgaged Properties
may consist of detached individual dwelling units, multifamily dwelling units,
individual condominiums, townhouses, duplexes, triplexes, fourplexes, row
houses, individual units in planned unit developments and other attached
dwelling units. The Mortgaged Properties may also include residential investment
properties and second homes.

      The investment characteristics of adjustable and fixed rate
mortgage-backed securities differ from those of traditional fixed-income
securities. The major differences include the payment of interest and principal
on mortgage-backed securities on a more frequent (usually monthly) schedule, and
the possibility that principal may be prepaid at any time due to prepayments on
the underlying mortgage loans or other assets. These differences can result in
significantly greater price and yield volatility than is the case with
traditional fixed-income securities. As a result, if a Fund purchases
mortgage-backed securities at a premium, a faster than expected prepayment rate
will reduce both the market value and the yield to maturity from those which
were anticipated. A prepayment rate that is slower than expected will have the
opposite effect of increasing yield to maturity and market value. Conversely, if
a Fund purchases mortgage-backed securities at a discount, faster than expected
prepayments will increase, while slower than expected prepayments will reduce
yield to maturity and market values. To the extent that a Fund invests in
mortgage-backed securities, its Investment Adviser may seek to manage these
potential risks by investing in a variety of mortgage-backed securities and by
using certain hedging techniques.

      Government Guaranteed Mortgage-Backed Securities. There are several types
of guaranteed mortgage-backed securities currently available, including
guaranteed mortgage pass-through certificates and multiple class securities,
which include guaranteed Real Estate Mortgage Investment Conduit Certificates
("REMIC Certificates"), collateralized mortgage obligations and stripped
mortgage-backed securities. A Fund is permitted to invest in other types of
mortgage-backed securities that may be available in the future to the extent
consistent with its investment policies and objective.

      A Fund's investments in mortgage-backed securities may include securities
issued or guaranteed by the U.S. Government or one of its agencies, authorities,
instrumentalities or sponsored enterprises, such as the Government National
Mortgage Association ("Ginnie Mae"), the Federal National Mortgage Association
("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac").

      Ginnie Mae Certificates. Ginnie Mae is a wholly-owned corporate
instrumentality of the United States. Ginnie Mae is authorized to guarantee the
timely payment of the principal of and interest on certificates that are based
on and backed by a pool of mortgage loans insured by the Federal Housing
Administration ("FHA Loans"), or guaranteed by the Veterans Administration


                                      B-17
<PAGE>
 
("VA Loans"), or by pools of other eligible mortgage loans. In order to meet its
obligations under any guaranty, Ginnie Mae is authorized to borrow from the
United States Treasury in an unlimited amount.

      Fannie Mae Certificates. Fannie Mae is a stockholder-owned corporation
chartered under an act of the United States Congress. Each Fannie Mae
Certificate is issued and guaranteed by Fannie Mae and represents an undivided
interest in a pool of mortgage loans (a "Pool") formed by Fannie Mae. Each Pool
consists of residential mortgage loans ("Mortgage Loans") either previously
owned by Fannie Mae or purchased by it in connection with the formation of the
Pool. The Mortgage Loans may be either conventional Mortgage Loans (i.e., not
insured or guaranteed by any U.S. Government agency) or Mortgage Loans that are
either insured by the Federal Housing Administration ("FHA") or guaranteed by
the Veterans Administration ("VA"). However, the Mortgage Loans in Fannie Mae
Pools are primarily conventional Mortgage Loans. The lenders originating and
servicing the Mortgage Loans are subject to certain eligibility requirements
established by Fannie Mae.

      Fannie Mae has certain contractual responsibilities. With respect to each
Pool, Fannie Mae is obligated to distribute scheduled monthly installments of
principal and interest after Fannie Mae's servicing and guaranty fee, whether or
not received, to Certificate holders. Fannie Mae also is obligated to distribute
to holders of Certificates an amount equal to the full principal balance of any
foreclosed Mortgage Loan, whether or not such principal balance is actually
recovered. The obligations of Fannie Mae under its guaranty of the Fannie Mae
Certificates are obligations solely of Fannie Mae.

      Freddie Mac Certificates. Freddie Mac is a publicly held U.S. Government
sponsored enterprise. The principal activity of Freddie Mac currently is the
purchase of first lien, conventional, residential mortgage loans and
participation interests in such mortgage loans and their resale in the form of
mortgage securities, primarily Freddie Mac Certificates. A Freddie Mac
Certificate represents a pro rata interest in a group of mortgage loans or
participation in mortgage loans (a "Freddie Mac Certificate group") purchased by
Freddie Mac.

      Freddie Mac guarantees to each registered holder of a Freddie Mac
Certificate the timely payment of interest at the rate provided for by such
Freddie Mac Certificate (whether or not received on the underlying loans).
Freddie Mac also guarantees to each registered Certificate holder ultimate
collection of all principal of the related mortgage loans, without any offset or
deduction, but does not, generally, guarantee the timely payment of scheduled
principal. The obligations of Freddie Mac under its guaranty of Freddie Mac
Certificates are obligations solely of Freddie Mac.

      The mortgage loans underlying the Freddie Mac and Fannie Mae Certificates
consist of adjustable rate or fixed rate mortgage loans with original terms to
maturity of between five and thirty years. Substantially all of these mortgage
loans are secured by first liens on one-to-four-family residential properties or
multifamily projects. Each mortgage loan must meet the applicable standards set
forth in the law creating Freddie Mac or Fannie Mae. A Freddie Mac Certificate
group may include whole loans, participation interests in whole loans and
undivided interests in whole loans and participations comprising another Freddie
Mac Certificate group.

      Mortgage Pass-Through Securities. Each Fund (other than CORE Large Cap
Value, CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap Equity and CORE
International Equity Funds) may invest in both government guaranteed and
privately issued mortgage pass-through securities ("Mortgage Pass-Throughs");
that is, fixed or adjustable rate mortgage-backed securities which provide for
monthly payments that are a "pass-through" of the monthly interest and principal
payments (including any prepayments) made by the individual borrowers on the
pooled mortgage loans, net of any fees or other amounts paid to any guarantor,
administrator and/or servicer of the underlying mortgage loans.

      The following discussion describes only a few of the wide variety of
structures of Mortgage Pass-Throughs that are available or may be issued.

      Description of Certificates. Mortgage Pass-Throughs may be issued in one
or more classes of senior certificates and one or more classes of subordinate
certificates. Each such class may bear a different pass-through rate. Generally,
each certificate will evidence the specified interest of the holder thereof in
the payments of principal or interest or both in respect of the mortgage pool
comprising part of the trust fund for such certificates.

      Any class of certificates may also be divided into subclasses entitled to
varying amounts of principal and interest. If a REMIC election has been made,
certificates of such subclasses may be entitled to payments on the basis of a
stated principal balance and stated interest rate, and payments among different
subclasses may be made on a sequential, concurrent, pro rata or disproportionate
basis, or any combination thereof. The stated interest rate on any such subclass
of certificates may be a fixed rate or one which varies in direct or inverse
relationship to an objective interest index.

      Generally, each registered holder of a certificate will be entitled to
receive its pro rata share of monthly distributions of all or a portion of
principal of the underlying mortgage loans or of interest on the principal
balances thereof, which accrues at the applicable mortgage pass-through rate, or
both. The difference between the mortgage interest rate and the related mortgage
pass-through rate (less the amount, if any, of retained yield) with respect to
each mortgage loan will generally be paid to the servicer as a servicing fee.
Since certain adjustable rate mortgage loans included in a mortgage pool may
provide for deferred interest (i.e., negative amortization), the amount of
interest actually paid by a mortgagor in any month may be less than the amount
of interest accrued on the outstanding principal balance of the related mortgage
loan during the relevant period at the applicable mortgage interest rate. In
such event, the amount of interest that is treated as deferred interest will be
added to the principal balance of the related mortgage loan and will be
distributed pro rata to certificate-holders as principal of such mortgage loan
when paid by the mortgagor in subsequent monthly payments or at maturity.

      Ratings. The ratings assigned by a rating organization to Mortgage
Pass-Throughs address the likelihood of the receipt of all distributions on the
underlying mortgage loans by the related certificate-holders under the
agreements pursuant to which such certificates are issued. A rating
organization's ratings take into consideration the credit quality of the related
mortgage pool, including any credit support providers, structural and legal
aspects associated with such certificates, and the extent to which the payment
stream on such mortgage pool is adequate to make payments required by such
certificates. A rating organization's ratings on such certificates do not,
however, constitute a statement regarding frequency of prepayments on the
related mortgage loans. In


                                      B-19
<PAGE>
 
addition, the rating assigned by a rating organization to a certificate does not
address the remote possibility that, in the event of the insolvency of the
issuer of certificates where a subordinated interest was retained, the issuance
and sale of the senior certificates may be recharacterized as a financing and,
as a result of such recharacterization, payments on such certificates may be
affected.

      Credit Enhancement. Credit support falls generally into two categories:
(i) liquidity protection and (ii) protection against losses resulting from
default by an obligor on the underlying assets. Liquidity protection refers to
the provision of advances, generally by the entity administering the pools of
mortgages, the provision of a reserve fund, or a combination thereof, to ensure,
subject to certain limitations, that scheduled payments on the underlying pool
are made in a timely fashion. Protection against losses resulting from default
ensures ultimate payment of the obligations on at least a portion of the assets
in the pool. Such credit support can be provided by, among other things, payment
guarantees, letters of credit, pool insurance, subordination, or any combination
thereof.

      Subordination; Shifting of Interest; Reserve Fund. In order to achieve
ratings on one or more classes of Mortgage Pass-Throughs, one or more classes of
certificates may be subordinate certificates which provide that the rights of
the subordinate certificate-holders to receive any or a specified portion of
distributions with respect to the underlying mortgage loans may be subordinated
to the rights of the senior certificate-holders. If so structured, the
subordination feature may be enhanced by distributing to the senior
certificate-holders on certain distribution dates, as payment of principal, a
specified percentage (which generally declines over time) of all principal
payments received during the preceding prepayment period ("shifting interest
credit enhancement"). This will have the effect of accelerating the amortization
of the senior certificates while increasing the interest in the trust fund
evidenced by the subordinate certificates. Increasing the interest of the
subordinate certificates relative to that of the senior certificates is intended
to preserve the availability of the subordination provided by the subordinate
certificates. In addition, because the senior certificate-holders in a shifting
interest credit enhancement structure are entitled to receive a percentage of
principal prepayments which is greater than their proportionate interest in the
trust fund, the rate of principal prepayments on the mortgage loans will have an
even greater effect on the rate of principal payments and the amount of interest
payments on, and the yield to maturity of, the senior certificates.

      In addition to providing for a preferential right of the senior
certificate-holders to receive current distributions from the mortgage pool, a
reserve fund may be established relating to such certificates (the "Reserve
Fund"). The Reserve Fund may be created with an initial cash deposit by the
originator or servicer and augmented by the retention of distributions otherwise
available to the subordinate certificate-holders or by excess servicing fees
until the Reserve Fund reaches a specified amount.

      The subordination feature, and any Reserve Fund, are intended to enhance
the likelihood of timely receipt by senior certificate-holders of the full
amount of scheduled monthly payments of principal and interest due them and will
protect the senior certificate-holders against certain losses; however, in
certain circumstances the Reserve Fund could be depleted and temporary
shortfalls could result. In the event the Reserve Fund is depleted before the
subordinated amount is reduced to zero, senior certificate-holders will
nevertheless have a preferential right to receive current distributions from the
mortgage pool to the extent of the then outstanding subordinated amount.


                                      B-20
<PAGE>
 
Unless otherwise specified, until the subordinated amount is reduced to zero, on
any distribution date any amount otherwise distributable to the subordinate
certificates or, to the extent specified, in the Reserve Fund will generally be
used to offset the amount of any losses realized with respect to the mortgage
loans ("Realized Losses"). Realized Losses remaining after application of such
amounts will generally be applied to reduce the ownership interest of the
subordinate certificates in the mortgage pool. If the subordinated amount has
been reduced to zero, Realized Losses generally will be allocated pro rata among
all certificate-holders in proportion to their respective outstanding interests
in the mortgage pool.

      Alternative Credit Enhancement. As an alternative, or in addition to the
credit enhancement afforded by subordination, credit enhancement for Mortgage
Pass-Throughs may be provided by mortgage insurance, hazard insurance, by the
deposit of cash, certificates of deposit, letters of credit, a limited guaranty
or by such other methods as are acceptable to a rating agency. In certain
circumstances, such as where credit enhancement is provided by guarantees or a
letter of credit, the security is subject to credit risk because of its exposure
to an external credit enhancement provider.

      Voluntary Advances. Generally, in the event of delinquencies in payments
on the mortgage loans underlying the Mortgage Pass-Throughs, the servicer agrees
to make advances of cash for the benefit of certificate-holders, but only to the
extent that it determines such voluntary advances will be recoverable from
future payments and collections on the mortgage loans or otherwise.

      Optional Termination. Generally, the servicer may, at its option with
respect to any certificates, repurchase all of the underlying mortgage loans
remaining outstanding at such time if the aggregate outstanding principal
balance of such mortgage loans is less than a specified percentage (generally
5-10%) of the aggregate outstanding principal balance of the mortgage loans as
of the cut-off date specified with respect to such series.

      Multiple Class Mortgage-Backed Securities and Collateralized Mortgage
Obligations. A Fund may invest in multiple class securities including
collateralized mortgage obligations ("CMOs") and REMIC Certificates. These
securities may be issued by U.S. Government agencies and instrumentalities such
as Fannie Mae or Freddie Mac or by trusts formed by private originators of, or
investors in, mortgage loans, including savings and loan associations, mortgage
bankers, commercial banks, insurance companies, investment banks and special
purpose subsidiaries of the foregoing. In general, CMOs are debt obligations of
a legal entity that are collateralized by, and multiple class mortgage-backed
securities represent direct ownership interests in, a pool of mortgage loans or
mortgage-backed securities the payments on which are used to make payments on
the CMOs or multiple class mortgage-backed securities.

      Fannie Mae REMIC Certificates are issued and guaranteed as to timely
distribution of principal and interest by Fannie Mae. In addition, Fannie Mae
will be obligated to distribute the principal balance of each class of REMIC
Certificates in full, whether or not sufficient funds are otherwise available.

      Freddie Mac guarantees the timely payment of interest on Freddie Mac REMIC
Certificates and also guarantees the payment of principal as payments are
required to be made on the underlying


                                      B-21
<PAGE>
 
mortgage participation certificates ("PCs"). PCs represent undivided interests
in specified level payment, residential mortgages or participation therein
purchased by Freddie Mac and placed in a PC pool. With respect to principal
payments on PCs, Freddie Mac generally guarantees ultimate collection of all
principal of the related mortgage loans without offset or deduction. Freddie Mac
also guarantees timely payment of principal of certain PCs.

      CMOs and guaranteed REMIC Certificates issued by Fannie Mae and Freddie
Mac are types of multiple class mortgage-backed securities. Investors may
purchase beneficial interests in REMICs, which are known as "regular" interests
or "residual" interests. The Funds do not intend to purchase residual interests
in REMICs. The REMIC Certificates represent beneficial ownership interests in a
REMIC trust, generally consisting of mortgage loans or Fannie Mae, Freddie Mac
or Ginnie Mae guaranteed mortgage-backed securities (the "Mortgage Assets"). The
obligations of Fannie Mae or Freddie Mac under their respective guaranty of the
REMIC Certificates are obligations solely of Fannie Mae or Freddie Mac,
respectively.

      CMOs and REMIC Certificates are issued in multiple classes. Each class of
CMOs or REMIC Certificates, often referred to as a "tranche," is issued at a
specific adjustable or fixed interest rate and must be fully retired no later
than its final distribution date. Principal prepayments on the Mortgage Loans or
the Mortgage Assets underlying the CMOs or REMIC Certificates may cause some or
all of the classes of CMOs or REMIC Certificates to be retired substantially
earlier than their final distribution dates. Generally, interest is paid or
accrues on all classes of CMOs or REMIC Certificates on a monthly basis.

      The principal of and interest on the Mortgage Assets may be allocated
among the several classes of CMOs or REMIC Certificates in various ways. In
certain structures (known as "sequential pay" CMOs or REMIC Certificates),
payments of principal, including any principal prepayments, on the Mortgage
Assets generally are applied to the classes of CMOs or REMIC Certificates in the
order of their respective final distribution dates. Thus, no payment of
principal will be made on any class of sequential pay CMOs or REMIC Certificates
until all other classes having an earlier final distribution date have been paid
in full.

      Additional structures of CMOs and REMIC Certificates include, among
others, "parallel pay" CMOs and REMIC Certificates. Parallel pay CMOs or REMIC
Certificates are those which are structured to apply principal payments and
prepayments of the Mortgage Assets to two or more classes concurrently on a
proportionate or disproportionate basis. These simultaneous payments are taken
into account in calculating the final distribution date of each class.

      A wide variety of REMIC Certificates may be issued in parallel pay or
sequential pay structures. These securities include accrual certificates (also
known as "Z-Bonds"), which only accrue interest at a specified rate until all
other certificates having an earlier final distribution date have been retired
and are converted thereafter to an interest-paying security, and planned
amortization class ("PAC") certificates, which are parallel pay REMIC
Certificates that generally require that specified amounts of principal be
applied on each payment date to one or more classes or REMIC Certificates (the
"PAC Certificates"), even though all other principal payments and prepayments of
the Mortgage Assets are then required to be applied to one or more other classes
of the Certificates. The scheduled principal payments for the PAC Certificates
generally have the highest priority on each payment date after interest due has
been paid to all classes entitled to


                                      B-22
<PAGE>
 
receive interest currently. Shortfalls, if any, are added to the amount payable
on the next payment date. The PAC Certificate payment schedule is taken into
account in calculating the final distribution date of each class of PAC. In
order to create PAC tranches, one or more tranches generally must be created
that absorb most of the volatility in the underlying mortgage assets. These
tranches tend to have market prices and yields that are much more volatile than
other PAC classes.

      Stripped Mortgage-Backed Securities. Balanced and Real Estate Securities
Funds may invest in stripped mortgage-backed securities ("SMBS"), which are
derivative multiclass mortgage securities. Although the market for such
securities is increasingly liquid, certain SMBS may not be readily marketable
and will be considered illiquid for purposes of the Fund's limitation on
investments in illiquid securities. The market value of the class consisting
entirely of principal payments generally is unusually volatile in response to
changes in interest rates. The yields on a class of SMBS that receives all or
most of the interest from Mortgage Assets are generally higher than prevailing
market yields on other mortgage-backed securities because their cash flow
patterns are more volatile and there is a greater risk that the initial
investment will not be fully recouped.

Inverse Floating Rate Securities

      Balanced and Real Estate Securities Funds may invest in leveraged inverse
floating rate debt instruments ("inverse floaters"). The interest rate on an
inverse floater resets in the opposite direction from the market rate of
interest to which the inverse floater is indexed. An inverse floater may be
considered to be leveraged to the extent that its interest rate varies by a
magnitude that exceeds the magnitude of the change in the index rate of
interest. The higher degree of leverage inherent in inverse floaters is
associated with greater volatility in their market values. Accordingly, the
duration of an inverse floater may exceed its stated final maturity. Certain
inverse floaters may be deemed to be illiquid securities for purposes of each
Fund's 15% limitation on investments in such securities.

Asset-Backed Securities

      Each Fund (except the CORE Large Cap Value, CORE U.S. Equity, CORE Large
Cap Growth, CORE Small Cap Equity and CORE International Equity Funds) may
invest in asset-backed securities. Asset-backed securities represent
participation in, or are secured by and payable from, assets such as motor
vehicle installment sales, installment loan contracts, leases of various types
of real and personal property, receivables from revolving credit (credit card)
agreements and other categories of receivables. Such assets are securitized
through the use of trusts and special purpose corporations. Payments or
distributions of principal and interest may be guaranteed up to certain amounts
and for a certain time period by a letter of credit or a pool insurance policy
issued by a financial institution unaffiliated with the trust or corporation, or
other credit enhancements may be present.

      Like mortgage-backed securities, asset-backed securities are often subject
to more rapid repayment than their stated maturity date would indicate as a
result of the pass-through of prepayments of principal on the underlying loans.
A Fund's ability to maintain positions in such securities will be affected by
reductions in the principal amount of such securities resulting from
prepayments, and its ability to reinvest the returns of principal at comparable
yields is subject to


                                      B-23
<PAGE>
 
generally prevailing interest rates at that time. To the extent that a Fund
invests in asset-backed securities, the values of such Fund's portfolio
securities will vary with changes in market interest rates generally and the
differentials in yields among various kinds of asset-backed securities.

      Asset-backed securities present certain additional risks that are not
presented by mortgage-backed securities because asset-backed securities
generally do not have the benefit of a security interest in collateral that is
comparable to mortgage assets. Credit card receivables are generally unsecured
and the debtors on such receivables are entitled to the protection of a number
of state and federal consumer credit laws, many of which give such debtors the
right to set-off certain amounts owed on the credit cards, thereby reducing the
balance due. Automobile receivables generally are secured, but by automobiles
rather than residential real property. Most issuers of automobile receivables
permit the loan servicers to retain possession of the underlying obligations. If
the servicer were to sell these obligations to another party, there is a risk
that the purchaser would acquire an interest superior to that of the holders of
the asset-backed securities. In addition, because of the large number of
vehicles involved in a typical issuance and technical requirements under state
laws, the trustee for the holders of the automobile receivables may not have a
proper security interest in the underlying automobiles. Therefore, there is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

Loan Participations

      Balanced Fund may invest in loan participations. Such loans must be to
issuers in whose obligations Balanced Fund may invest. A loan participation is
an interest in a loan to a U.S. or foreign company or other borrower which is
administered and sold by a financial intermediary. In a typical corporate loan
syndication, a number of lenders, usually banks (co-lenders), lend a corporate
borrower a specified sum pursuant to the terms and conditions of a loan
agreement. One of the co-lenders usually agrees to act as the agent bank with
respect to the loan.

      Participation interests acquired by Balanced Fund may take the form of a
direct or co-lending relationship with the corporate borrower, an assignment of
an interest in the loan by a co-lender or another participant, or a
participation in the seller's share of the loan. When Balanced Fund acts as
co-lender in connection with a participation interest or when Balanced Fund
acquires certain participation interests, Balanced Fund will have direct
recourse against the borrower if the borrower fails to pay scheduled principal
and interest. In cases where Balanced Fund lacks direct recourse, it will look
to the agent bank to enforce appropriate credit remedies against the borrower.
In these cases, Balanced Fund may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Fund had purchased a
direct obligation (such as commercial paper) of such borrower. For example, in
the event of the bankruptcy or insolvency of the corporate borrower, a loan
participation may be subject to certain defenses by the borrower as a result of
improper conduct by the agent bank. Moreover, under the terms of the loan
participation, Balanced Fund may be regarded as a creditor of the agent bank
(rather than of the underlying corporate borrower), so that Balanced Fund may
also be subject to the risk that the agent bank may become insolvent. The
secondary market, if any, for these loan participations is limited and any loan
participations purchased by the Balanced Fund will be regarded as illiquid.

      For purposes of certain investment limitations pertaining to
diversification of the Balanced Fund's portfolio investments, the issuer of a
loan participation will be the underlying borrower.


                                      B-24
<PAGE>
 
However, in cases where the Balanced Fund does not have recourse directly
against the borrower, both the borrower and each agent bank and co-lender
interposed between the Balanced Fund and the borrower will be deemed issuers of
a loan participation.

Futures Contracts and Options on Futures Contracts

      Each Fund may purchase and sell futures contracts and may also purchase
and write options on futures contracts. CORE Large Cap Value, CORE Large Cap
Growth and CORE Small Cap Equity Funds may only enter into such transactions
with respect to a representative index. CORE U.S. Equity Fund may enter into
futures transactions only with respect to the S&P 500 Index. The other Funds may
purchase and sell futures contracts based on various securities (such as U.S.
Government securities), securities indices, foreign currencies and other
financial instruments and indices. Each Fund will engage in futures and related
options transactions, only for bona fide hedging purposes as defined below or
for purposes of seeking to increase total return to the extent permitted by
regulations of the Commodity Futures Trading Commission ("CFTC"). Futures
contracts entered into by a Fund are traded on U.S. exchanges or boards of trade
that are licensed and regulated by the CFTC or on foreign exchanges. Neither the
CFTC, National Futures Association nor any domestic exchange regulates
activities of any foreign exchange or boards of trade, including the execution,
delivery and clearing of transactions, or has the power to compel enforcement of
the rules of a foreign exchange or board of trade or any applicable foreign law.
This is true even if the exchange is formally linked to a domestic market so
that a position taken on the market may be liquidated by a transaction on
another market. Moreover, such laws or regulations will vary depending on the
foreign country in which the foreign futures or foreign options transaction
occurs. For these reasons, persons who trade foreign futures or foreign options
contracts may not be afforded certain of the protective measures provided by the
Commodity Exchange Act, the CFTC's regulations and the rules of the National
Futures Association and any domestic exchange, including the right to use
reparations proceedings before the CFTC and arbitration proceedings provided by
the National Futures Association or any domestic futures exchange. In
particular, a Fund's investments in foreign futures or foreign options
transactions may not be provided the same protections in respect of transactions
on United States futures exchanges.

      Futures Contracts. A futures contract may generally be described as an
agreement between two parties to buy and sell particular financial instruments
for an agreed price during a designated month (or to deliver the final cash
settlement price, in the case of a contract relating to an index or otherwise
not calling for physical delivery at the end of trading in the contract).

      When interest rates are rising or securities prices are falling, a Fund
can seek through the sale of futures contracts to offset a decline in the value
of its current portfolio securities. When rates are falling or prices are
rising, a Fund, through the purchase of futures contracts, can attempt to secure
better rates or prices than might later be available in the market when it
effects anticipated purchases. Similarly, each Fund (other than CORE Large Cap
Value, CORE U.S. Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds)
can purchase and sell futures contracts on a specified currency in order to seek
to increase total return or to hedge against changes in currency exchange rates.
Each Fund (other than CORE Large Cap Value, CORE U.S. Equity, CORE Large Cap
Growth and CORE Small Cap Equity Funds) can purchase futures contracts on
foreign currency to establish the price in U.S. dollars of a security quoted or
denominated in such currency that such Fund has acquired or expects to acquire.
Balanced Fund may also use futures contracts to


                                      B-25
<PAGE>
 
manage the term structure and duration of its fixed-income securities holdings
in accordance with that Fund's investment objectives and policies.

      Positions taken in the futures market are not normally held to maturity,
but are instead liquidated through offsetting transactions which may result in a
profit or a loss. While each Fund will usually liquidate futures contracts on
securities or currency in this manner, a Fund may instead make or take delivery
of the underlying securities or currency whenever it appears economically
advantageous for the Fund to do so. A clearing corporation associated with the
exchange on which futures are traded guarantees that, if still open, the sale or
purchase will be performed on the settlement date.

      Hedging Strategies. Hedging, by use of futures contracts, seeks to
establish with more certainty than would otherwise be possible the effective
price, rate of return or currency exchange rate on portfolio securities or
securities that a Fund owns or proposes to acquire. A Fund may, for example,
take a "short" position in the futures market by selling futures contracts to
seek to hedge against an anticipated rise in interest rates or a decline in
market prices or (other than CORE Large Cap Value, CORE U.S. Equity, CORE Large
Cap Growth and CORE Small Cap Equity Funds) foreign currency rates that would
adversely affect the dollar value of such Fund's portfolio securities.
Similarly, each Fund (other than CORE Large Cap Value, CORE U.S. Equity, CORE
Large Cap Growth and CORE Small Cap Equity Funds) may sell futures contracts on
a currency in which its portfolio securities are quoted or denominated or in one
currency to seek to hedge against fluctuations in the value of securities quoted
or denominated in a different currency if there is an established historical
pattern of correlation between the two currencies. If, in the opinion of the
applicable Investment Adviser, there is a sufficient degree of correlation
between price trends for a Fund's portfolio securities and futures contracts
based on other financial instruments, securities indices or other indices, a
Fund may also enter into such futures contracts as part of its hedging strategy.
Although under some circumstances prices of securities in a Fund's portfolio may
be more or less volatile than prices of such futures contracts, the Investment
Advisers will attempt to estimate the extent of this volatility difference based
on historical patterns and compensate for any such differential by having a Fund
enter into a greater or lesser number of futures contracts or by attempting to
achieve only a partial hedge against price changes affecting a Fund's securities
portfolio. When hedging of this character is successful, any depreciation in the
value of portfolio securities will be substantially offset by appreciation in
the value of the futures position. On the other hand, any unanticipated
appreciation in the value of a Fund's portfolio securities would be
substantially offset by a decline in the value of the futures position.

      On other occasions, a Fund may take a "long" position by purchasing such
futures contracts. This would be done, for example, when a Fund anticipates the
subsequent purchase of particular securities when it has the necessary cash, but
expects the prices or currency exchange rates then available in the applicable
market to be less favorable than prices or rates that are currently available.

      Options on Futures Contracts. The acquisition of put and call options on
futures contracts will give a Fund the right (but not the obligation), for a
specified price, to sell or to purchase, respectively, the underlying futures
contract at any time during the option period. As the purchaser of an option on
a futures contract, a Fund obtains the benefit of the futures position if prices
move in


                                      B-26
<PAGE>
 
a favorable direction but limits its risk of loss in the event of an unfavorable
price movement to the loss of the premium and transaction costs.

      The writing of a call option on a futures contract generates a premium
which may partially offset a decline in the value of a Fund's assets. By writing
a call option, a Fund becomes obligated, in exchange for the premium, to sell a
futures contract if the option is exercised, which may have a value higher than
the exercise price. Conversely, the writing of a put option on a futures
contract generates a premium, which may partially offset an increase in the
price of securities that a Fund intends to purchase. However, a Fund becomes
obligated to purchase a futures contract if the option is exercised, which may
have a value lower than the exercise price. Thus, the loss incurred by a Fund in
writing options on futures is potentially unlimited and may exceed the amount of
the premium received. A Fund will incur transaction costs in connection with the
writing of options on futures.

      The holder or writer of an option on a futures contract may terminate its
position by selling or purchasing an offsetting option on the same financial
instrument. There is no guarantee that such closing transactions can be
effected. A Fund's ability to establish and close out positions on such options
will be subject to the development and maintenance of a liquid market.

      Other Considerations. Each Fund will engage in futures transactions and
will engage in related options transactions only for bona fide hedging as
defined in the regulations of the CFTC or to seek to increase total return to
the extent permitted by such regulations.

      In addition to bona fide hedging, a CFTC regulation permits a Fund to
engage in other future transactions if the aggregate initial margin and premiums
required to establish such positions in futures contracts and options on futures
do not exceed 5% of the net asset value of such Fund's portfolio, after taking
into account unrealized profits and losses on any such positions and excluding
the amount by which such options were in-the-money at the time of purchase. A
Fund will engage in transactions in futures contracts and, for a Fund permitted
to do so, related options transactions only to the extent such transactions are
consistent with the requirements of the Code for maintaining its qualification
as a regulated investment company for federal income tax purposes.

      Transactions in futures contracts and options on futures involve brokerage
costs, require margin deposits and, in certain cases, require the Fund to
segregate with its custodian cash or liquid assets in an amount equal to the
underlying value of such contracts and options.

      While transactions in futures contracts and options on futures may reduce
certain risks, such transactions themselves entail certain other risks. Thus,
unanticipated changes in interest rates, securities prices or currency exchange
rates may result in a poorer overall performance for a Fund than if it had not
entered into any futures contracts or options transactions. In the event of an
imperfect correlation between a futures position and a portfolio position which
is intended to be protected, the desired protection may not be obtained and a
Fund may be exposed to risk of loss.

      Perfect correlation between a Fund's futures positions and portfolio
positions will be difficult to achieve because no futures contracts based on
individual equity or corporate fixed-income securities are currently available.
In addition, it is not possible for a Fund to hedge fully or perfectly against
currency fluctuations affecting the value of securities quoted or denominated in


                                      B-27
<PAGE>
 
foreign currencies because the value of such securities is likely to fluctuate
as a result of independent factors not related to currency fluctuations. The
profitability of a Fund's trading in futures depends upon the ability of the
Investment Adviser to analyze correctly the futures markets.

Options on Securities and Securities Indices

      Writing Covered Options. Each Fund may write (sell) covered call and put
options on any securities in which it may invest. A call option written by a
Fund obligates such Fund to sell specified securities to the holder of the
option at a specified price if the option is exercised at any time before the
expiration date. All call options written by a Fund are covered, which means
that such Fund will own the securities subject to the option as long as the
option is outstanding or such Fund will use the other methods described below. A
Fund's purpose in writing covered call options is to realize greater income than
would be realized on portfolio securities transactions alone. However, a Fund
may forego the opportunity to profit from an increase in the market price of the
underlying security.

      A put option written by a Fund would obligate such Fund to purchase
specified securities from the option holder at a specified price if the option
is exercised at any time before the expiration date. All put options written by
a Fund would be covered, which means that such Fund will segregate cash or
liquid assets with a value at least equal to the exercise price of the put
option or will use the other methods described below. The purpose of writing
such options is to generate additional income for the Fund. However, in return
for the option premium, each Fund accepts the risk that it may be required to
purchase the underlying securities at a price in excess of the securities'
market value at the time of purchase.

      Call and put options written by a Fund will also be considered to be
covered to the extent that the Fund's liabilities under such options are wholly
or partially offset by its rights under call and put options purchased by the
Fund or by an offsetting forward contract which, by virtue of its exercise price
or otherwise, reduces a Fund's net exposure on its written option position.

      A Fund may also write (sell) covered call and put options on any
securities index consisting of securities in which it may invest. Options on
securities indices are similar to options on securities, except that the
exercise of securities index options requires cash payments and does not involve
the actual purchase or sale of securities. In addition, securities index options
are designed to reflect price fluctuations in a group of securities or segment
of the securities market rather than price fluctuations in a single security.

      A Fund may cover call options on a securities index by owning securities
whose price changes are expected to be similar to those of the underlying index,
or by having an absolute and immediate right to acquire such securities without
additional cash consideration (or for additional cash consideration which has
been segregated by the Fund) upon conversion or exchange of other securities in
its portfolio. A Fund may cover call and put options on a securities index by
segregating cash or liquid assets with a value equal to the exercise price.

      A Fund may terminate its obligations under an exchange traded call or put
option by purchasing an option identical to the one it has written. Obligations
under over-the-counter options


                                      B-28
<PAGE>
 
may be terminated only by entering into an offsetting transaction with the
counterparty to such option. Such purchases are referred to as "closing purchase
transactions."

      Purchasing Options. Each Fund may purchase put and call options on any
securities in which it may invest or options on any securities index composed of
securities in which it may invest. A Fund would also be able to enter into
closing sale transactions in order to realize gains or minimize losses on
options it had purchased.

      A Fund may purchase call options in anticipation of an increase in the
market value of securities of the type in which it may invest. The purchase of a
call option would entitle a Fund, in return for the premium paid, to purchase
specified securities at a specified price during the option period. A Fund would
ordinarily realize a gain if, during the option period, the value of such
securities exceeded the sum of the exercise price, the premium paid and
transaction costs; otherwise such a Fund would realize either no gain or a loss
on the purchase of the call option.

      A Fund may purchase put options in anticipation of a decline in the market
value of securities in its portfolio ("protective puts") or in securities in
which it may invest. The purchase of a put option would entitle a Fund, in
exchange for the premium paid, to sell specified securities at a specified price
during the option period. The purchase of protective puts is designed to offset
or hedge against a decline in the market value of a Fund's securities. Put
options may also be purchased by a Fund for the purpose of affirmatively
benefiting from a decline in the price of securities which it does not own. A
Fund would ordinarily realize a gain if, during the option period, the value of
the underlying securities decreased below the exercise price sufficiently to
more than cover the premium and transaction costs; otherwise such a Fund would
realize either no gain or a loss on the purchase of the put option. Gains and
losses on the purchase of protective put options would tend to be offset by
countervailing changes in the value of the underlying portfolio securities.

      A Fund would purchase put and call options on securities indices for the
same purposes as it would purchase options on individual securities. For a
description of options on securities indices, see "Writing Covered Options"
above.

      Yield Curve Options. Balanced and Real Estate Securities Funds may enter
into options on the yield "spread" or differential between two securities. Such
transactions are referred to as "yield curve" options. In contrast to other
types of options, a yield curve option is based on the difference between the
yields of designated securities, rather than the prices of the individual
securities, and is settled through cash payments. Accordingly, a yield curve
option is profitable to the holder if this differential widens (in the case of a
call) or narrows (in the case of a put), regardless of whether the yields of the
underlying securities increase or decrease.

      Balanced and Real Estate Securities Funds may purchase or write yield
curve options for the same purposes as other options on securities. For example,
each Fund may purchase a call option on the yield spread between two securities
if it owns one of the securities and anticipates purchasing the other security
and wants to hedge against an adverse change in the yield spread between the two
securities. Balanced and Real Estate Securities Funds may also purchase or write
yield curve options in an effort to increase current income if, in the judgment
of the Investment Adviser, a Fund will be able to profit from movements in the
spread between the yields of the underlying securities. The trading of yield
curve options is subject to all of the risks associated with the trading of
other


                                      B-29
<PAGE>
 
types of options. In addition, however, such options present risk of loss
even if the yield of one of the underlying securities remains constant, if the
spread moves in a direction or to an extent which was not anticipated.

      Yield curve options written by Balanced and Real Estate Securities Funds
will be "covered." A call (or put) option is covered if a Fund holds another
call (or put) option on the spread between the same two securities and
segregates cash or liquid assets sufficient to cover a Fund's net liability
under the two options. Therefore, a Fund's liability for such a covered option
is generally limited to the difference between the amount of such Fund's
liability under the option written by the Fund less the value of the option held
by the Fund. Yield curve options may also be covered in such other manner as may
be in accordance with the requirements of the counterparty with which the option
is traded and applicable laws and regulations. Yield curve options are traded
over-the-counter, and because they have been only recently introduced,
established trading markets for these options have not yet developed.

      Risks Associated with Options Transactions. There is no assurance that a
liquid secondary market on an options exchange will exist for any particular
exchange-traded option or at any particular time. If a Fund is unable to effect
a closing purchase transaction with respect to covered options it has written,
the Fund will not be able to sell the underlying securities or dispose of
segregated assets until the options expire or are exercised. Similarly, if a
Fund is unable to effect a closing sale transaction with respect to options it
has purchased, it will have to exercise the options in order to realize any
profit and will incur transaction costs upon the purchase or sale of underlying
securities.

      Reasons for the absence of a liquid secondary market on an exchange
include the following: (i) there may be insufficient trading interest in certain
options; (ii) restrictions may be imposed by an exchange on opening or closing
transactions or both; (iii) trading halts, suspensions or other restrictions may
be imposed with respect to particular classes or series of options; (iv) unusual
or unforeseen circumstances may interrupt normal operations on an exchange; (v)
the facilities of an exchange or the Options Clearing Corporation may not at all
times be adequate to handle current trading volume; or (vi) one or more
exchanges could, for economic or other reasons, decide or be compelled at some
future date to discontinue the trading of options (or a particular class or
series of options), in which event the secondary market on that exchange (or in
that class or series of options) would cease to exist, although outstanding
options on that exchange that had been issued by the Options Clearing
Corporation as a result of trades on that exchange would continue to be
exercisable in accordance with their terms.

      Each Fund may purchase and sell both options that are traded on U.S. and
foreign exchanges and options traded over-the-counter with broker-dealers who
make markets in these options. The ability to terminate over-the-counter options
is more limited than with exchange-traded options and may involve the risk that
broker-dealers participating in such transactions will not fulfill their
obligations.

      Transactions by each Fund in options on securities and indices will be
subject to limitations established by each of the exchanges, boards of trade or
other trading facilities governing the maximum number of options in each class
which may be written or purchased by a single investor or group of investors
acting in concert. Thus, the number of options which a Fund may write or


                                      B-30
<PAGE>
 
purchase may be affected by options written or purchased by other investment
advisory clients of the Investment Advisers. An exchange, board of trade or
other trading facility may order the liquidation of positions found to be in
excess of these limits, and it may impose certain other sanctions.

      The writing and purchase of options is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions. The use of options to seek to
increase total return involves the risk of loss if the Investment Adviser is
incorrect in its expectation of fluctuations in securities prices or interest
rates. The successful use of options for hedging purposes also depends in part
on the ability of the Investment Adviser to manage future price fluctuations and
the degree of correlation between the options and securities markets. If the
Investment Adviser is incorrect in its expectation of changes in securities
prices or determination of the correlation between the securities indices on
which options are written and purchased and the securities in a Fund's
investment portfolio, the investment performance of the Fund will be less
favorable than it would have been in the absence of such options transactions.
The writing of options could increase a Fund's portfolio turnover rate and,
therefore, associated brokerage commissions or spreads.

Real Estate Investment Trusts

      Each Fund may invest in shares of REITs. The Real Estate Securities Fund
expects that a substantial portion of its total assets will be invested in
REITs. REITs are pooled investment vehicles which invest primarily in income
producing real estate or real estate related loans or interest. REITs are
generally classified as equity REITs, mortgage REITs or a combination of equity
and mortgage REITs. Equity REITs invest the majority of their assets directly in
real property and derive income primarily from the collection of rents. Equity
REITs can also realize capital gains by selling properties that have appreciated
in value. Mortgage REITs invest the majority of their assets in real estate
mortgages and derive income from the collection of interest payments. Like
regulated investment companies such as the Funds, REITs are not taxed on income
distributed to shareholders provided they comply with certain requirements under
the Code. A Fund will indirectly bear its proportionate share of any expenses
paid by REITs in which it invests in addition to the expenses paid by a Fund.

      Investing in REITs involves certain unique risks. Equity REITs may be
affected by changes in the value of the underlying property owned by such REITs,
while mortgage REITs may be affected by the quality of any credit extended.
REITs are dependent upon management skills, are not diversified (except to the
extent the Code requires), and are subject to the risks of financing projects.
REITs are subject to heavy cash flow dependency, default by borrowers,
self-liquidation, and the possibilities of failing to qualify for the exemption
from tax for distributed income under the Code and failing to maintain their
exemptions from the Act. REITs (especially mortgage REITs) are also subject to
interest rate risks.

Warrants and Stock Purchase Rights

      Each Fund may invest in warrants or rights (other than those acquired in
units or attached to other securities) which entitle the holder to buy equity
securities at a specific price for a specific period of time. A Fund will invest
in warrants and rights only if such equity securities are deemed


                                      B-31
<PAGE>
 
appropriate by the Investment Adviser for investment by the Fund. CORE Large Cap
Value, CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap Equity and CORE
International Equity Funds have no present intention of acquiring warrants or
rights. Warrants and rights have no voting rights, receive no dividends and have
no rights with respect to the assets of the issuer.

Foreign Securities

      Each Fund may invest in securities of foreign issuers. The Balanced,
Growth and Income, CORE International Equity, Capital Growth, Strategic Growth,
Growth Opportunities, MidCap Value, International Equity, Small Cap Value,
European Equity, Japanese Equity, International Small Cap, Emerging Markets
Equity, Asia Growth and Real Estate Securities Funds may invest in the aggregate
up to 10%, 25%, 90%, 10%, 10%, 10%, 25%, 65%, 25%, 65%, 65%, 65%, 65%, 65% and
15%, respectively, of their total assets in foreign securities. With respect to
the CORE U.S. Equity, CORE Large Cap Growth, CORE Large Cap Value and CORE Small
Cap Equity Funds, equity securities of foreign issuers must be traded in the
United States.

      Investments in foreign securities may offer potential benefits not
available from investments solely in U.S. dollar-denominated or quoted
securities of domestic issuers. Such benefits may include the opportunity to
invest in foreign issuers that appear, in the opinion of the applicable
Investment Adviser, to offer the potential for long-term growth of capital and
income, the opportunity to invest in foreign countries with economic policies or
business cycles different from those of the United States and the opportunity to
reduce fluctuations in portfolio value by taking advantage of foreign stock
markets that do not necessarily move in a manner parallel to U.S. markets.

      Investing in foreign securities involves certain special risks, including
those set forth below, which are not typically associated with investing in U.S.
dollar-denominated or quoted securities of U.S. issuers. Investments in foreign
securities usually involve currencies of foreign countries. Accordingly, any
Fund that invests in foreign securities may be affected favorably or unfavorably
by changes in currency rates and in exchange control regulations and may incur
costs in connection with conversions between various currencies. Balanced,
Growth and Income, CORE International Equity, Capital Growth, Strategic Growth,
Growth Opportunities, Mid Cap Value, International Equity, Small Cap Value,
European Equity, Japanese Equity, International Small Cap, Emerging Markets
Equity, Asia Growth and Real Estate Securities Funds may be subject to currency
exposure independent of their securities positions. To the extent that a Fund is
fully invested in foreign securities while also maintaining currency positions,
it may be exposed to greater combined risk.

      Currency exchange rates may fluctuate significantly over short periods of
time. They generally are determined by the forces of supply and demand in the
foreign exchange markets and the relative merits of investments in different
countries, actual or anticipated changes in interest rates and other complex
factors, as seen from an international perspective. Currency exchange rates also
can be affected unpredictably by intervention by U.S. or foreign governments or
central banks or the failure to intervene or by currency controls or political
developments in the United States or abroad.

      Since foreign issuers generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies,


                                      B-32
<PAGE>
 
there may be less publicly available information about a foreign company than
about a U.S. company. Volume and liquidity in most foreign securities markets
are less than in the United States and securities of many foreign companies are
less liquid and more volatile than securities of comparable U.S. companies.
Fixed commissions on foreign securities exchanges are generally higher than
negotiated commissions on U.S. exchanges, although each Fund endeavors to
achieve the most favorable net results on its portfolio transactions. There is
generally less government supervision and regulation of foreign securities
exchanges, brokers, dealers and listed and unlisted companies than in the United
States.

      Foreign markets also have different clearance and settlement procedures,
and in certain markets there have been times when settlements have been unable
to keep pace with the volume of securities transactions, making it difficult to
conduct such transactions. Such delays in settlement could result in temporary
periods when some of a Fund's assets are uninvested and no return is earned on
such assets. The inability of a Fund to make intended security purchases due to
settlement problems could cause the Fund to miss attractive investment
opportunities. Inability to dispose of portfolio securities due to settlement
problems could result either in losses to the Fund due to subsequent declines in
value of the portfolio securities or, if the Fund has entered into a contract to
sell the securities, could result in possible liability to the purchaser. In
addition, with respect to certain foreign countries, there is the possibility of
expropriation or confiscatory taxation, political or social instability, or
diplomatic developments which could affect a Fund's investments in those
countries. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, capital reinvestment, resource self-sufficiency and
balance of payments position.

      Each Fund may invest in foreign securities which take the form of
sponsored and unsponsored American Depository Receipts ("ADRs") and Global
Depository Receipts ("GDRs") and (except for CORE Large Cap Value, CORE U.S.
Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds) may also invest
in European Depository Receipts ("EDRs") or other similar instruments
representing securities of foreign issuers (together, "Depository Receipts").

      ADRs represent the right to receive securities of foreign issuers
deposited in a domestic bank or a correspondent bank. ADRs are traded on
domestic exchanges or in the U.S. over-the-counter market and, generally, are in
registered form. EDRs and GDRs are receipts evidencing an arrangement with a
non-U.S. bank similar to that for ADRs and are designed for use in the non-U.S.
securities markets. EDRs and GDRs are not necessarily quoted in the same
currency as the underlying security.

      To the extent a Fund acquires Depository Receipts through banks which do
not have a contractual relationship with the foreign issuer of the security
underlying the Depository Receipts to issue and service such Depository Receipts
(unsponsored), there may be an increased possibility that the Fund would not
become aware of and be able to respond to corporate actions such as stock splits
or rights offerings involving the foreign issuer in a timely manner. In
addition, the lack of information may result in inefficiencies in the valuation
of such instruments. Investment in Depository Receipts does not eliminate all
the risks inherent in investing in securities of non-U.S. issuers. The market
value of Depository Receipts is dependent upon the market value of the
underlying securities and fluctuations in the relative value of the currencies
in which the Depository receipts and the underlying securities are quoted.
However, by investing in


                                      B-33
<PAGE>
 
Depository Receipts, such as ADRs, that are quoted in U.S. dollars, a Fund may
avoid currency risks during the settlement period for purchases and sales.

      As described more fully below, each Fund (except CORE Large Cap Value,
CORE U.S. Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds) may
invest in countries with emerging economies or securities markets. Political and
economic structures in many of such countries may be undergoing significant
evolution and rapid development, and such countries may lack the social,
political and economic stability characteristic of more developed countries.
Certain of such countries may have in the past failed to recognize private
property rights and have at times nationalized or expropriated the assets of
private companies. As a result, the risks described above, including the risks
of nationalization or expropriation of assets, may be heightened. See "Investing
in Emerging Markets, including Asia and Eastern Europe," below.

      Investing in Emerging Countries, including Asia and Eastern Europe. CORE
International Equity, International Equity, European Equity, Japanese Equity,
International Small Cap, Asia Growth and Emerging Markets Equity Funds are
intended for long-term investors who can accept the risks associated with
investing primarily in equity and equity-related securities of foreign issuers,
including (for certain Funds) emerging country issuers, as well as the risks
associated with investments quoted or denominated in foreign currencies.
Balanced, Growth and Income, Capital Growth, Strategic Growth, Growth
Opportunities, Mid Cap Value, Small Cap Value, and Real Estate Securities Funds
may invest, to a lesser extent, in equity and equity-related securities of
foreign issuers, including emerging country issuers.

      Each of the securities markets of the emerging countries is less liquid
and subject to greater price volatility and has a smaller market capitalization
than the U.S. securities markets. Issuers and securities markets in such
countries are not subject to as extensive and frequent accounting, financial and
other reporting requirements or as comprehensive government regulations as are
issuers and securities markets in the U.S. In particular, the assets and profits
appearing on the financial statements of emerging country issuers may not
reflect their financial position or results of operations in the same manner as
financial statements for U.S. issuers. Substantially less information may be
publicly available about emerging country issuers than is available about
issuers in the United States.

      Emerging country securities markets are typically marked by a high
concentration of market capitalization and trading volume in a small number of
issuers representing a limited number of industries, as well as a high
concentration of ownership of such securities by a limited number of investors.
The markets for securities in certain emerging countries are in the earliest
stages of their development. Even the markets for relatively widely traded
securities in emerging countries may not be able to absorb, without price
disruptions, a significant increase in trading volume or trades of a size
customarily undertaken by institutional investors in the securities markets of
developed countries. The limited size of many of these securities markets can
cause prices to be erratic for reasons apart from factors that affect the
soundness and competitiveness of the securities issuers. For example, prices may
be unduly influenced by traders who control large positions in these markets.
Additionally, market making and arbitrage activities are generally less
extensive in such markets, which may contribute to increased volatility and
reduced liquidity of such markets. The limited liquidity of emerging country
markets may also affect a Fund's ability to accurately value its


                                      B-34
<PAGE>
 
portfolio securities or to acquire or dispose of securities at the price and
time it wishes to do so or in order to meet redemption requests.

      Transaction costs, including brokerage commissions or dealer mark-ups, in
emerging countries may be higher than in the United States and other developed
securities markets. In addition, existing laws and regulations are often
inconsistently applied. As legal systems in emerging countries develop, foreign
investors may be adversely affected by new or amended laws and regulations. In
circumstances where adequate laws exist, it may not be possible to obtain swift
and equitable enforcement of the law.

      Foreign investment in the securities markets of certain emerging countries
is restricted or controlled to varying degrees. These restrictions may limit a
Fund's investment in certain emerging countries and may increase the expenses of
the Fund. Certain emerging countries require governmental approval prior to
investments by foreign persons or limit investment by foreign persons to only a
specified percentage of an issuer's outstanding securities or a specific class
of securities which may have less advantageous terms (including price) than
securities of the company available for purchase by nationals. In addition, the
repatriation of both investment income and capital from several of the emerging
countries is subject to restrictions which require governmental consents or
prohibit repatriation entirely for a period of time. Even where there is no
outright restriction on repatriation of capital, the mechanics of repatriation
may affect certain aspects of the operation of a Fund. A Fund may be required to
establish special custodial or other arrangements before investing in certain
emerging countries.

      Each of the emerging countries may be subject to a substantially greater
degree of economic, political and social instability and disruption than is the
case in the United States, Japan and most Western European countries. This
instability may result from, among other things, the following: (i)
authoritarian governments or military involvement in political and economic
decision making, including changes or attempted changes in governments through
extra-constitutional means; (ii) popular unrest associated with demands for
improved political, economic or social conditions; (iii) internal insurgencies;
(iv) hostile relations with neighboring countries; (v) ethnic, religious and
racial disaffection or conflict; and (vi) the absence of developed legal
structures governing foreign private investments and private property. Such
economic, political and social instability could disrupt the principal financial
markets in which the Funds may invest and adversely affect the value of the
Funds' assets. A Fund's investments could in the future be adversely affected by
any increase in taxes or by political, economic or diplomatic developments.
Certain Funds may seek investment opportunities within former "east bloc"
countries in Eastern Europe. See "Fund Investment Objectives and Strategies" in
the prospectus. All or a substantial portion of such investments may be
considered "not readily marketable" for purposes of the limitation set forth
below. For example, most Eastern European countries have had a centrally
planned, socialist economy since shortly after World War II. The governments of
a number of Eastern European countries currently are implementing reforms
directed at political and economic liberalization, including efforts to
decentralize the economic decision-making process and move towards a market
economy. However, business entities in many Eastern European countries do not
have any recent history of operating in a market-oriented economy, and the
ultimate impact of Eastern European countries' attempts to move toward more
market-oriented economies is currently unclear. In addition, any change in the
leadership or policies of Eastern European countries may halt the expansion of
or reverse the liberalization of foreign investment policies now occurring and
adversely affect existing investment opportunities. To the extent a Fund invests
in an issuer located (1) in a country which was formerly part of Yugoslavia, (2)
in a country that shares a border with the former country of Yugoslavia, (3) in 
a country which is a member of the North Atlantic Treaty Organization ("NATO"), 
or (4) in other countries in Europe, such Fund could suffer investment losses 
as a result of the recent conflict between Serbia and members of NATO.  The NATO
bombing campaign and proposed oil embargo (if implemented) could adversely 
affect a Fund's investments.  The extent to which this conflict may broaden and 
involve other countries such as Russia is unpredictable, and the impact this 
conflict may have on a Fund is uncertain.

                                      B-35
<PAGE>
 
      The economies of emerging countries may differ unfavorably from the U.S.
economy in such respects as growth of gross domestic product, rate of inflation,
capital reinvestment, resources, self-sufficiency and balance of payments. Many
emerging countries have experienced in the past, and continue to experience,
high rates of inflation. In certain countries inflation has at times accelerated
rapidly to hyperinflationary levels, creating a negative interest rate
environment and sharply eroding the value of outstanding financial assets in
those countries. The economies of many emerging countries are heavily dependent
upon international trade and are accordingly affected by protective trade
barriers and the economic conditions of their trading partners. In addition, the
economies of some emerging countries are vulnerable to weakness in world prices
for their commodity exports.

      A Fund's income and, in some cases, capital gains from foreign stocks and
securities will be subject to applicable taxation in certain of the countries in
which it invests, and treaties between the U.S. and such countries may not be
available in some cases to reduce the otherwise applicable tax rates. See
"Taxation."

      Foreign markets also have different clearance and settlement procedures,
and in certain markets there have been times when settlements have been unable
to keep pace with the volume of securities transactions, making it difficult to
conduct such transactions. Such delays in settlement could result in temporary
periods when a portion of the assets of a Fund remain uninvested and no return
is earned on such assets. The inability of a Fund to make intended security
purchases or sales due to settlement problems could result either in losses to
the Fund due to subsequent declines in value of the portfolio securities or, if
the Fund has entered into a contract to sell the securities, could result in
possible liability to the purchaser.

      Investing in Japan. The Japanese Equity Fund invests in the equity
securities of Japanese companies. Japan's economy, the second-largest in the
world, has grown substantially over the last three decades. The boom in Japan's
equity and property markets during the expansion of the late 1980's supported
high rates of investment and consumer spending on durable goods, but both of
these components of demand have now retreated sharply following the decline in
asset prices. Profits have fallen sharply, unemployment has reached a historical
high and consumer confidence is low. The banking sector continues to suffer from
non-performing loans and this economy is subject to deflationary pressures.
Numerous discount-rate cuts since its peak in 1991, a succession of fiscal
stimulus packages, support plans for the debt-burdened financial system and
spending for reconstruction following the Kobe earthquake may help to contain
the recessionary forces, but substantial uncertainties remain.

      In addition to the cyclical downturn, Japan is suffering through
structural adjustments. Like the Europeans, the Japanese have seen a
deterioration of their competitiveness due to high wages, a strong currency and
structural rigidities. Finally, Japan is reforming its political process and
deregulating its economy. This has brought about turmoil, uncertainty and a
crisis of confidence.

      While the Japanese governmental system itself seems stable, the dynamics
of the country's politics have been unpredictable in recent years. The economic
crisis of 1990-92 brought the


                                      B-36
<PAGE>
 
downfall of the conservative Liberal Democratic Party, which had ruled since
1955. Since then, the country has seen a series of unstable multi-party
coalitions and several prime ministers come and go, because of politics as well
as personal scandals. While there appears to be no reason for anticipating civic
unrest, it is impossible to know when the political instability will end and
what trade and fiscal policies might be pursued by the government that emerges.

      Japan's heavy dependence on international trade has been adversely
affected by trade tariffs and other protectionist measures as well as the
economic condition of its trading partners. While Japan subsidizes its
agricultural industry, only 19% of its land is suitable for cultivation and it
is only 50% self-sufficient in food production. Accordingly, it is highly
dependent on large imports of wheat, sorghum and soybeans. In addition,
industry, its most important economic sector, depends on imported raw materials
and fuels, including iron ore, copper, oil and many forest products. Japan's
high volume of exports, such as automobiles, machine tools and semiconductors,
have caused trade tensions, particularly with the United States. Some trade
agreements, however, have been implemented to reduce these tensions. The
relaxing of official and de facto barriers to imports, or hardships created by
any pressures brought by trading partners, could adversely affect Japan's
economy. A substantial rise in world oil or commodity prices could also have a
negative affect. The strength of the yen itself may prove an impediment to
strong continued exports and economic recovery, because it makes Japanese goods
sold in other countries more expensive and reduces the value of foreign earnings
repatriated to Japan. Because the Japanese economy is so dependent on exports,
any fall-off in exports may be seen as a sign of economic weakness, which may
adversely affect the market.

      Geologically, Japan is located in a volatile area of the world, and has
historically been vulnerable to earthquakes, volcanoes and other natural
disasters. As demonstrated by the Kobe earthquake in January of 1995, in which
5,000 people were killed and billions of dollars of damage was sustained, these
natural disasters can be significant enough to affect the country's economy.

      Forward Foreign Currency Exchange Contracts. Growth and Income, CORE Large
Cap Value, CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap Equity,
Capital Growth, Strategic Growth, Growth Opportunities, Mid Cap Value, Small Cap
Value and Real Estate Securities Funds may enter into forward foreign currency
exchange contracts for hedging purposes and to seek to protect against
anticipated changes in future foreign currency exchange rates. Balanced, CORE
International Equity, International Equity, European Equity, Japanese Equity,
International Small Cap, Emerging Markets Equity and Asia Growth Funds may enter
into forward foreign currency exchange contracts for hedging purposes and to
seek to increase total return. A forward foreign currency exchange contract
involves an obligation to purchase or sell a specific currency at a future date,
which may be any fixed number of days from the date of the contract agreed upon
by the parties, at a price set at the time of the contract. These contracts are
traded in the interbank market between currency traders (usually large
commercial banks) and their customers. A forward contract generally has no
deposit requirement, and no commissions are generally charged at any stage for
trades.

      At the maturity of a forward contract a Fund may either accept or make
delivery of the currency specified in the contract or, at or prior to maturity,
enter into a closing transaction involving the purchase or sale of an offsetting
contract. Closing transactions with respect to forward


                                      B-37
<PAGE>
 
contracts are often, but not always, effected with the currency trader who is a
party to the original forward contract.

      A Fund may enter into forward foreign currency exchange contracts in
several circumstances. First, when a Fund enters into a contract for the
purchase or sale of a security denominated or quoted in a foreign currency, or
when a Fund anticipates the receipt in a foreign currency of dividend or
interest payments on such a security which it holds, the Fund may desire to
"lock in" the U.S. dollar price of the security or the U.S. dollar equivalent of
such dividend or interest payment, as the case may be. By entering into a
forward contract for the purchase or sale, for a fixed amount of dollars, of the
amount of foreign currency involved in the underlying transactions, the Fund
will attempt to protect itself against an adverse change in the relationship
between the U.S. dollar and the subject foreign currency during the period
between the date on which the security is purchased or sold, or on which the
dividend or interest payment is declared, and the date on which such payments
are made or received.

      Additionally, when the Investment Adviser believes that the currency of a
particular foreign country may suffer a substantial decline against the U.S.
dollar, it may enter into a forward contract to sell, for a fixed amount of U.S.
dollars, the amount of foreign currency approximating the value of some or all
of such Fund's portfolio securities quoted or denominated in such foreign
currency. The precise matching of the forward contract amounts and the value of
the securities involved will not generally be possible because the future value
of such securities in foreign currencies will change as a consequence of market
movements in the value of those securities between the date on which the
contract is entered into and the date it matures. Using forward contracts to
protect the value of a Fund's portfolio securities against a decline in the
value of a currency does not eliminate fluctuations in the underlying prices of
the securities. It simply establishes a rate of exchange which a Fund can
achieve at some future point in time. The precise projection of short-term
currency market movements is not possible, and short-term hedging provides a
means of fixing the U.S. dollar value of only a portion of a Fund's foreign
assets.

      Balanced, CORE International Equity, International Equity, European
Equity, Japanese Equity, International Small Cap, Emerging Markets Equity and
Asia Growth Funds may engage in cross-hedging by using forward contracts in one
currency to hedge against fluctuations in the value of securities quoted or
denominated in a different currency if GSAM or GSAMI determines that there is a
pattern of correlation between the two currencies.

      Balanced, CORE International Equity, International Equity, European
Equity, Japanese Equity, International Small Cap, Emerging Markets Equity and
Asia Growth Funds may also enter into forward contracts to seek to increase
total return. Unless otherwise covered in accordance with applicable
regulations, cash or liquid assets of a Fund will be segregated in an amount
equal to the value of the Fund's total assets committed to the consummation of
forward foreign currency exchange contracts. The segregated assets will be
marked-to-market on a daily basis. If the value of the segregated assets
declines, additional cash or liquid assets will be segregated on a daily basis
so that the value of the assets will equal the amount of a Fund's commitments
with respect to such contracts. Although the contracts are not presently
regulated by the CFTC, the CFTC may in the future assert authority to regulate
these contracts. In such event, a Fund's ability to utilize forward foreign
currency exchange contracts may be restricted.


                                      B-38
<PAGE>
 
      While a Fund may enter into forward contracts to reduce currency exchange
rate risks, transactions in such contracts involve certain other risks. Thus,
while the Fund may benefit from such transactions, unanticipated changes in
currency prices may result in a poorer overall performance for the Fund than if
it had not engaged in any such transactions. Moreover, there may be imperfect
correlation between a Fund's portfolio holdings of securities quoted or
denominated in a particular currency and forward contracts entered into by such
Fund. Such imperfect correlation may cause a Fund to sustain losses which will
prevent the Fund from achieving a complete hedge or expose the Fund to risk of
foreign exchange loss.

      Markets for trading foreign forward currency contracts offer less
protection against defaults than is available when trading in currency
instruments on an exchange. Forward contracts are subject to the risk that the
counterparty to such contract will default on its obligations. Since a forward
foreign currency exchange contract is not guaranteed by an exchange or
clearinghouse, a default on the contract would deprive a Fund of unrealized
profits, transaction costs or the benefits of a currency hedge or force the Fund
to cover its purchase or sale commitments, if any, at the current market price.
A Fund will not enter into forward foreign currency exchange contracts, currency
swaps or other privately negotiated currency instruments unless the credit
quality of the unsecured senior debt or the claims-paying ability of the
counterparty is considered to be investment grade by the Investment Adviser. To
the extent that a substantial portion of a Fund's total assets, adjusted to
reflect the Fund's net position after giving effect to currency transactions, is
denominated or quoted in the currencies of foreign countries, the Fund will be
more susceptible to the risk of adverse economic and political developments
within those countries.

      Writing and Purchasing Currency Call and Put Options. Each Fund may, to
the extent that it invests in foreign securities, write and purchase put and
call options on foreign currencies for the purpose of protecting against
declines in the U.S. dollar value of foreign portfolio securities and against
increases in the U.S. dollar cost of foreign securities to be acquired. As with
other kinds of option transactions, however, the writing of an option on foreign
currency will constitute only a partial hedge, up to the amount of the premium
received. If and when a Fund seeks to close out an option, the Fund could be
required to purchase or sell foreign currencies at disadvantageous exchange
rates, thereby incurring losses. The purchase of an option on foreign currency
may constitute an effective hedge against exchange rate fluctuations; however,
in the event of exchange rate movements adverse to a Fund's position, the Fund
may forfeit the entire amount of the premium plus related transaction costs.
Options on foreign currencies to be written or purchased by a Fund will be
traded on U.S. and foreign exchanges or over-the-counter.

      Options on currency may be used for either hedging or cross-hedging
purposes, which involves writing or purchasing options on one currency to hedge
against changes in exchange rates for a different currency with a pattern of
correlation, or to seek to increase total return when the Investment Adviser
anticipates that the currency will appreciate or depreciate in value, but the
securities quoted or denominated in that currency do not present attractive
investment opportunities and are not included in the Fund's portfolio.

      A call option written by a Fund obligates a Fund to sell a specified
currency to the holder of the option at a specified price if the option is
exercised at any time before the expiration date. A put option written by a Fund
would obligate a Fund to purchase a specified currency from the option holder at
a specified price if the option is exercised at any time before the expiration
date. The


                                      B-39
<PAGE>
 
writing of currency options involves a risk that a Fund will, upon exercise of
the option, be required to sell currency subject to a call at a price that is
less than the currency's market value or be required to purchase currency
subject to a put at a price that exceeds the currency's market value. For a
description of how to cover written put and call options, see "Writing Covered
Options" above.

      A Fund may terminate its obligations under a call or put option by
purchasing an option identical to the one it has written. Such purchases are
referred to as "closing purchase transactions." A Fund may enter into closing
sale transactions in order to realize gains or minimize losses on options
purchased by the Fund.

      A Fund would normally purchase call options on foreign currency in
anticipation of an increase in the U.S. dollar value of currency in which
securities to be acquired by a Fund are quoted or denominated. The purchase of a
call option would entitle the Fund, in return for the premium paid, to purchase
specified currency at a specified price during the option period. A Fund would
ordinarily realize a gain if, during the option period, the value of such
currency exceeded the sum of the exercise price, the premium paid and
transaction costs; otherwise the Fund would realize either no gain or a loss on
the purchase of the call option.

      A Fund would normally purchase put options in anticipation of a decline in
the U.S. dollar value of currency in which securities in its portfolio are
quoted or denominated ("protective puts"). The purchase of a put option would
entitle a Fund, in exchange for the premium paid, to sell specified currency at
a specified price during the option period. The purchase of protective puts is
designed merely to offset or hedge against a decline in the dollar value of a
Fund's portfolio securities due to currency exchange rate fluctuations. A Fund
would ordinarily realize a gain if, during the option period, the value of the
underlying currency decreased below the exercise price sufficiently to more than
cover the premium and transaction costs; otherwise the Fund would realize either
no gain or a loss on the purchase of the put option. Gains and losses on the
purchase of protective put options would tend to be offset by countervailing
changes in the value of underlying currency or portfolio securities.

      In addition to using options for the hedging purposes described above, the
Funds may use options on currency to seek to increase total return. The Funds
may write (sell) covered put and call options on any currency in order to
realize greater income than would be realized on portfolio securities
transactions alone. However, in writing covered call options for additional
income, the Funds may forego the opportunity to profit from an increase in the
market value of the underlying currency. Also, when writing put options, the
Funds accept, in return for the option premium, the risk that they may be
required to purchase the underlying currency at a price in excess of the
currency's market value at the time of purchase.

      Special Risks Associated With Options on Currency. An exchange traded
options position may be closed out only on an options exchange which provides a
secondary market for an option of the same series. Although a Fund will
generally purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market on
an exchange will exist for any particular option, or at any particular time. For
some options no secondary market on an exchange may exist. In such event, it
might not be possible to effect closing transactions in particular options, with
the result that a Fund would have to exercise its options in order to realize
any profit and would incur transaction costs upon the sale of


                                      B-40
<PAGE>
 
underlying securities pursuant to the exercise of put options. If a Fund as a
covered call option writer is unable to effect a closing purchase transaction in
a secondary market, it will not be able to sell the underlying currency (or
security quoted or denominated in that currency) until the option expires or it
delivers the underlying currency upon exercise.

      There is no assurance that higher than anticipated trading activity or
other unforeseen events might not, at times, render certain of the facilities of
the Options Clearing Corporation inadequate, and thereby result in the
institution by an exchange of special procedures which may interfere with the
timely execution of customers' orders.

      A Fund may purchase and write over-the-counter options to the extent
consistent with its limitation on investments in illiquid securities. Trading in
over-the-counter options is subject to the risk that the other party will be
unable or unwilling to close out options purchased or written by a Fund.

      The amount of the premiums which a Fund may pay or receive may be
adversely affected as new or existing institutions, including other investment
companies, engage in or increase their option purchasing and writing activities.

Currency Swaps, Mortgage Swaps, Credit Swaps, Index Swaps and Interest Rate
Swaps, Caps, Floors and Collars

      Balanced, Real Estate Securities, CORE International Equity, International
Equity, European Equity, Japanese Equity, International Small Cap, Emerging
Markets Equity and Asia Growth Funds may enter into currency swaps for both
hedging purposes and to seek to increase total return. In addition, Balanced and
Real Estate Securities Funds may enter into mortgage, credit, index and interest
rate swaps and other interest rate swap arrangements such as rate caps, floors
and collars, for hedging purposes or to seek to increase total return. Currency
swaps involve the exchange by a Fund with another party of their respective
rights to make or receive payments in specified currencies. Interest rate swaps
involve the exchange by a Fund with another party of their respective
commitments to pay or receive interest, such as an exchange of fixed rate
payments for floating rate payments. Mortgage swaps are similar to interest rate
swaps in that they represent commitments to pay and receive interest. The
notional principal amount, however, is tied to a reference pool or pools of
mortgages. Index swaps involve the exchange by a Fund with another party of the
respective amounts payable with respect to a notional principal amount at
interest rates equal to two specified indices. Credit swaps involve the receipt
of floating or fixed rate payments in exchange for assuming potential credit
losses of an underlying security. Credit swaps give one party to a transaction
the right to dispose of or acquire an asset (or group of assets), or the right
to receive or make a payment for the other party, upon the occurrence of
specified credit events. The purchase of an interest rate cap entitles the
purchaser, to the extent that a specified index exceeds a predetermined interest
rate, to receive payment of interest on a notional principal amount from the
party selling such interest rate cap. The purchase of an interest rate floor
entitles the purchaser, to the extent that a specified index falls below a
predetermined interest rate, to receive payments of interest on a notional
principal amount from the party selling the interest rate floor. An interest
rate collar is the combination of a cap and a floor that preserves a certain
return within a predetermined range of interest rates.


                                      B-41
<PAGE>
 
      A Fund will enter into interest rate, mortgage and index swaps only on a
net basis, which means that the two payment streams are netted out, with the
Fund receiving or paying, as the case may be, only the net amount of the two
payments. Interest rate, index and mortgage swaps do not involve the delivery of
securities, other underlying assets or principal. Accordingly, the risk of loss
with respect to interest rate, index and mortgage swaps is limited to the net
amount of interest payments that the Fund is contractually obligated to make. If
the other party to an interest rate, index or mortgage swap defaults, the Fund's
risk of loss consists of the net amount of interest payments that the Fund is
contractually entitled to receive. In contrast, currency swaps usually involve
the delivery of a gross payment stream in one designated currency in exchange
for the gross payment stream in another designated currency. Therefore, the
entire payment stream under a currency swap is subject to the risk that the
other party to the swap will default on its contractual delivery obligations. To
the extent that the Fund's potential exposure in a transaction involving a swap
or an interest rate floor, cap or collar is covered by the segregation of cash
or liquid assets or otherwise, the Funds and the Investment Advisers believe
that swaps do not constitute senior securities under the Act and, accordingly,
will not treat them as being subject to a Fund's borrowing restrictions.

      A Fund will not enter into transactions involving swaps, caps, floors or
collars unless the unsecured commercial paper, senior debt or claims paying
ability of the other party thereto is considered to be investment grade by the
Investment Adviser.

      The use of interest rate, mortgage, index, credit and currency swaps, as
well as interest rate caps, floors and collars, is a highly specialized activity
which involves investment techniques and risks different from those associated
with ordinary portfolio securities transactions. If an Investment Adviser is
incorrect in its forecasts of market values, interest rates and currency
exchange rates, the investment performance of a Fund would be less favorable
than it would have been if this investment technique were not used. The
Investment Advisers, under the supervision of the Board of Trustees, are
responsible for determining and monitoring the liquidity of the Funds'
transactions in swaps, caps, floors and collars.

Convertible Securities

      Each Fund may invest in convertible securities. Convertible securities
include corporate notes or preferred stock but are ordinarily long-term debt
obligation of the issuer convertible at a stated exchange rate into common stock
of the issuer. As with all debt securities, the market value of convertible
securities tends to decline as interest rates increase and, conversely, to
increase as interest rates decline. Convertible securities generally offer lower
interest or dividend yields than non-convertible securities of similar quality.
However, when the market price of the common stock underlying a convertible
security exceeds the conversion price, the price of the convertible security
tends to reflect the value of the underlying common stock. As the market price
of the underlying common stock declines, the convertible security tends to trade
increasingly on a yield basis, and thus may not depreciate to the same extent as
the underlying common stock. Convertible securities rank senior to common stocks
in an issuer's capital structure and consequently entail less risk than the
issuer's common stock. In evaluating a convertible security, the Investment
Adviser will give primary emphasis to the attractiveness of the underlying
common stock. Convertible debt securities are equity investments for purposes of
each Fund's investment policies.


                                      B-42
<PAGE>
 
Preferred Securities

      Each Fund may invest in preferred securities. Unlike debt securities, the
obligations of an issuer of preferred stock, including dividend and other
payment obligations, may not typically be accelerated by the holders of
preferred stock on the occurrence of an event of default (such as a covenant
default or filing of a bankruptcy petition) or other non-compliance by the
issuer with the terms of the preferred stock. Often, however, on the occurrence
of any such event of default or non-compliance by the issuer, preferred
stockholders will be entitled to gain representation on the issuer's board of
directors or increase their existing board representation. In addition,
preferred stockholders may be granted voting rights with respect to certain
issues on the occurrence of any event of default.

Equity Swaps

      Each Fund may enter into equity swap contracts to invest in a market
without owning or taking physical custody of securities in circumstances in
which direct investment is restricted for legal reasons or is otherwise
impracticable. Equity swaps may also be used for hedging purposes or to seek to
increase total return. The counterparty to an equity swap contract will
typically be a bank, investment banking firm or broker/dealer. Equity swap
contracts may be structured in different ways. For example, a counterparty may
agree to pay the Fund the amount, if any, by which the notional amount of the
equity swap contract would have increased in value had it been invested in the
particular stocks (or an index of stocks), plus the dividends that would have
been received on those stocks. In these cases, the Fund may agree to pay to the
counterparty a floating rate of interest on the notional amount of the equity
swap contract plus the amount, if any, by which that notional amount would have
decreased in value had it been invested in such stocks. Therefore, the return to
the Fund on the equity swap contract should be the gain or loss on the notional
amount plus dividends on the stocks less the interest paid by the Fund on the
notional amount. In other cases, the counterparty and the Fund may each agree to
pay the other the difference between the relative investment performances that
would have been achieved if the notional amount of the equity swap contract had
been invested in different stocks (or indices of stocks).

      A Fund will enter into equity swaps only on a net basis, which means that
the two payment streams are netted out, with the Fund receiving or paying, as
the case may be, only the net amount of the two payments. Payments may be made
at the conclusion of an equity swap contract or periodically during its term.
Equity swaps do not involve the delivery of securities or other underlying
assets. Accordingly, the risk of loss with respect to equity swaps is limited to
the net amount of payments that a Fund is contractually obligated to make. If
the other party to an equity swap defaults, a Fund's risk of loss consists of
the net amount of payments that such Fund is contractually entitled to receive,
if any. Inasmuch as these transactions are entered into for hedging purposes or
are offset by segregated cash or liquid assets to cover the Funds' potential
exposure, the Funds and their Investment Advisers believe that transactions do
not constitute senior securities under the Act and, accordingly, will not treat
them as being subject to a Fund's borrowing restrictions.

      A Fund will not enter into swap transactions unless the unsecured
commercial paper, senior debt or claims paying ability of the other party
thereto is considered to be investment grade by the Investment Adviser.

Lending of Portfolio Securities

      Each Fund may lend portfolio securities. Under present regulatory
policies, such loans may be made to institutions, such as brokers or dealers and
would be required to be secured continuously by collateral in cash, cash
equivalents, letters of credit or U.S. Government securities maintained on a
current basis at an amount at least equal to the market value of the securities
loaned. A Fund would be required to have the right to call a loan and obtain the
securities loaned at any time on five days' notice. For the duration of a loan,
a Fund would continue to receive the equivalent of the interest or dividends
paid by the issuer on the securities loaned and would also receive compensation
from investment of the collateral. A Fund would not have the right to vote any
securities having voting rights during the existence of the loan, but a Fund
would call the loan in anticipation of an important vote to be taken among
holders of the securities or the giving or withholding of their consent on a
material matter affecting the investment. As with other extensions of credit
there are risks of delay in recovering, or even loss of rights in, the
collateral should the borrower of the securities fail financially. However, the
loans would be made only to firms deemed by the Investment Advisers to be of
good standing, and when, in the judgment of the Investment Advisers, the
consideration which can be earned currently from securities loans of this type
justifies the attendant risk. If the Investment Advisers determine to make
securities loans, it is intended that the value of the securities loaned would
not exceed one-third of the value of the total assets of a Fund (including the
loan collateral).

When-Issued Securities and Forward Commitments

      Each Fund may purchase securities on a when-issued basis or purchase or
sell securities on a forward commitment basis. These transactions involve a
commitment by a Fund to purchase or sell securities at a future date. The price
of the underlying securities (usually expressed in terms of yield) and the date
when the securities will be delivered and paid for (the settlement date) are
fixed at the time the transaction is negotiated. When-issued purchases and
forward commitment transactions are negotiated directly with the other party,
and such commitments are not traded on exchanges. A Fund will purchase
securities on a when-issued basis or purchase or sell securities on a forward
commitment basis only with the intention of completing the transaction and
actually purchasing or selling the securities. If deemed advisable as a matter
of investment strategy, however, a Fund may dispose of or negotiate a commitment
after entering into it. A Fund may realize a capital gain or loss in connection
with these transactions. For purposes of determining a Fund's duration, the
maturity of when-issued or forward commitment securities will be calculated from
the commitment date. A Fund is required to segregate until three days prior to
the settlement date, cash and liquid assets in an amount sufficient to meet the
purchase price. Alternatively, a Fund may enter into offsetting contracts for
the forward sale of other securities that it owns. Securities purchased or sold
on a when-issued or forward commitment basis involve a risk of loss if the value
of the security to be purchased declines prior to the settlement date or if the
value of the security to be sold increases prior to the settlement date.

Investment in Unseasoned Companies

      Each Fund may invest in companies (including predecessors) which have
operated less than three years, except that this limitation does not apply to
debt securities which have been rated


                                      B-44
<PAGE>
 
investment grade or better by at least one NRSRO. The securities of such
companies may have limited liquidity, which can result in their being priced
higher or lower than might otherwise be the case. In addition, investments in
unseasoned companies are more speculative and entail greater risk than do
investments in companies with an established operating record.

Other Investment Companies

      A Fund reserves the right to invest up to 10% of its total assets in the
securities of all investment companies (including SPDRs) but may not acquire
more than 3% of the voting securities of any other investment company. Pursuant
to an exemptive order obtained from the SEC, the Funds may invest in money
market funds for which an Investment Adviser or any of its affiliates serves as
investment Adviser. A Fund will indirectly bear its proportionate share of any
management fees and other expenses paid by investment companies in which it
invests in addition to the advisory and administration fees paid by the Fund.
However, to the extent that the Fund invests in a money market fund for which an
Investment Adviser or any of its affiliates acts as Investment Adviser, the
advisory and administration fees payable by the Fund to an Investment Adviser
will be reduced by an amount equal to the Fund's proportionate share of the
advisory and administration fees paid by such money market fund to the
Investment Adviser.

      SPDRs are interests in a unit investment trust ("UIT") that may be
obtained from the UIT or purchased in the secondary market (SPDRs are listed on
the American Stock Exchange). There is a 5% limit based on total assets on
investments by any one Fund in SPDRs. The UIT will issue SPDRs in aggregations
known as "Creation Units" in exchange for a "Portfolio Deposit" consisting of
(a) a portfolio of securities substantially similar to the component securities
("Index Securities") of the Standard & Poor's 500 Composite Stock Price Index
(the "S&P Index"), (b) a cash payment equal to a pro rata portion of the
dividends accrued on the UIT's portfolio securities since the last dividend
payment by the UIT, net of expenses and liabilities, and (c) a cash payment or
credit ("Balancing Amount") designed to equalize the net asset value of the S&P
Index and the net asset value of a Portfolio Deposit.

      SPDRs are not individually redeemable, except upon termination of the UIT.
To redeem, the Portfolio must accumulate enough SPDRs to reconstitute a Creation
Unit. The liquidity of small holdings of SPDRs, therefore, will depend upon the
existence of a secondary market. Upon redemption of a Creation Unit, the
Portfolio will receive Index Securities and cash identical to the Portfolio
Deposit required of an investor wishing to purchase a Creation Unit that day.

      The price of SPDRs is derived from and based upon the securities held by
the UIT. Accordingly, the level of risk involved in the purchase or sale of a
SPDR is similar to the risk involved in the purchase or sale of traditional
common stock, with the exception that the pricing mechanism for SPDRs is based
on a basket of stocks. Disruptions in the markets for the securities underlying
SPDRs purchased or sold by the Funds could result in losses on SPDRs.

      Each Fund (other than CORE Large Cap Value, CORE U.S. Equity, CORE Large
Cap Growth and CORE Small Cap Equity Funds) may also purchase shares of
investment companies investing primarily in foreign securities, including
"country funds." Country funds have portfolios consisting primarily of
securities of issuers located in one foreign country or region. Each Fund


                                      B-45
<PAGE>
 
may, subject to the limitations stated above, invest in World Equity Benchmark
Shares ("WEBS") and similar securities that invest in securities included in
foreign securities indices.

Repurchase Agreements

      Each Fund may enter into repurchase agreements with dealers in U.S.
Government securities and member banks of the Federal Reserve System which
furnish collateral at least equal in value or market price to the amount of
their repurchase obligation. CORE International Equity, International Equity,
Japanese Equity, European Equity, International Small Cap, Emerging Markets
Equity, Asia Growth and Balanced Funds may also enter into repurchase agreements
involving certain foreign government securities. A repurchase agreement is an
arrangement under which a Fund purchases securities and the seller agrees to
repurchase the securities within a particular time and at a specified price.
Custody of the securities is maintained by a Fund's custodian (or subcustodian).
The repurchase price may be higher than the purchase price, the difference being
income to a Fund, or the purchase and repurchase prices may be the same, with
interest at a stated rate due to a Fund together with the repurchase price on
repurchase. In either case, the income to a Fund is unrelated to the interest
rate on the security subject to the repurchase agreement.

      For purposes of the Act and generally for tax purposes, a repurchase
agreement is deemed to be a loan from a Fund to the seller of the security. For
other purposes, it is not always clear whether a court would consider the
security purchased by a Fund subject to a repurchase agreement as being owned by
a Fund or as being collateral for a loan by a Fund to the seller. In the event
of commencement of bankruptcy or insolvency proceedings with respect to the
seller of the security before repurchase of the security under a repurchase
agreement, a Fund may encounter delay and incur costs before being able to sell
the security. Such a delay may involve loss of interest or a decline in price of
the security. If the court characterizes the transaction as a loan and a Fund
has not perfected a security interest in the security, a Fund may be required to
return the security to the seller's estate and be treated as an unsecured
creditor of the seller. As an unsecured creditor, a Fund would be at risk of
losing some or all of the principal and interest involved in the transaction.

      The Investment Advisers seek to minimize the risk of loss from repurchase
agreements by analyzing the creditworthiness of the obligor, in this case the
seller of the security. Apart from the risk of bankruptcy or insolvency
proceedings, there is also the risk that the seller may fail to repurchase the
security. However, if the market value of the security subject to the repurchase
agreement becomes less than the repurchase price (including accrued interest), a
Fund will direct the seller of the security to deliver additional securities so
that the market value of all securities subject to the repurchase agreement
equals or exceeds the repurchase price. Certain repurchase agreements which
provide for settlement in more than seven days can be liquidated before the
nominal fixed term on seven days or less notice. Such repurchase agreements will
be regarded as liquid instruments.

      In addition, a Fund, together with other registered investment companies
having advisory agreements with the Investment Advisers or their affiliates, may
transfer uninvested cash balances into a single joint account, the daily
aggregate balance of which will be invested in one or more repurchase
agreements.


                                      B-46
<PAGE>
 
Reverse Repurchase Agreements

      A Fund may borrow money by entering into transactions called reverse
repurchase agreements. Under these arrangements, the Fund will sell portfolio
securities to dealers in U.S. Government Securities or members of the Federal
Reserve System, with an agreement to repurchase the security on an agreed date,
price and interest payment. Reverse repurchase agreements involve the possible
risk that the value of portfolio securities the Fund relinquishes may decline
below the price the Fund must pay when the transaction closes. Borrowings may
magnify the potential for gain or loss on amounts invested resulting in an
increase in the speculative character of the Fund's outstanding shares.

      When a Fund enters into a reverse repurchase agreement, it places in a
separate custodial account either liquid assets or other high grade debt
securities that have a value equal to or greater than the repurchase price. The
account is then continuously monitored to make sure that an appropriate value is
maintained. Reverse repurchase agreements are considered to be borrowings under
the Act.

Mortgage Dollar Rolls

      When Balanced and Real Estate Securities Fund enters into a mortgage
dollar roll, it will segregate cash or liquid assets in an amount equal to the
forward purchase price until the settlement date.

Portfolio Turnover

      Each Fund may engage in active short-term trading to benefit from yield
disparities among different issues of securities or among the markets for equity
securities, or for other reasons. It is anticipated that the portfolio turnover
rate of each Fund will vary from year to year.

                             INVESTMENT RESTRICTIONS

      The following investment restrictions have been adopted by the Trust as
fundamental policies that cannot be changed without the affirmative vote of the
holders of a majority (as defined in the Act) of the outstanding voting
securities of the affected Fund. The investment objective of each Fund and all
other investment policies or practices of each Fund are considered by the Trust
not to be fundamental and accordingly may be changed without shareholder
approval. See "Investment Objectives and Policies" in the Prospectus. For
purposes of the Act, "majority" means the lesser of (a) 67% or more of the
shares of the Trust or a Fund present at a meeting, if the holders of more than
50% of the outstanding shares of the Trust or a Fund are present or represented
by proxy, or (b) more than 50% of the shares of the Trust or a Fund. For
purposes of the following limitations, any limitation which involves a maximum
percentage shall not be considered violated unless an excess over the percentage
occurs immediately after, and is caused by, an acquisition or encumbrance of
securities or assets of, or borrowings by, a Fund. With respect to the Funds'
fundamental investment restriction no. 3, asset coverage of at least 300% (as
defined in the Act), inclusive of any amounts borrowed, must be maintained at
all times.


                                      B-47

      A Fund may not:

            (1)   Make any investment inconsistent with the Fund's
                  classification as a diversified company under the Investment
                  Company Act of 1940, as amended (the "Act"). This restriction
                  does not, however, apply to any Fund classified as a
                  non-diversified company under the Act.

            (2)   Invest 25% or more of its total assets in the securities of
                  one or more issuers conducting their principal business
                  activities in the same industry (other than the Goldman Sachs
                  Real Estate Securities Fund, which will invest at least 25% or
                  more of its total assets in the real estate industry)
                  (excluding the U.S. Government or any of its agencies or
                  instrumentalities).

            (3)   Borrow money, except (a) the Fund may borrow from banks (as
                  defined in the Act) or through reverse repurchase agreements
                  in amounts up to 33-1/3% of its total assets (including the
                  amount borrowed), (b) the Fund may, to the extent permitted by
                  applicable law, borrow up to an additional 5% of its total
                  assets for temporary purposes, (c) the Fund may obtain such
                  short-term credits as may be necessary for the clearance of
                  purchases and sales of portfolio securities, (d) the Fund may
                  purchase securities on margin to the extent permitted by
                  applicable law and (e) the Fund may engage in transactions in
                  mortgage dollar rolls which are accounted for as financings.

            (4)   Make loans, except through (a) the purchase of debt
                  obligations in accordance with the Fund's investment objective
                  and policies, (b) repurchase agreements with banks, brokers,
                  dealers and other financial institutions, and (c) loans of
                  securities as permitted by applicable law.

            (5)   Underwrite securities issued by others, except to the extent
                  that the sale of portfolio securities by the Fund may be
                  deemed to be an underwriting.

            (6)   Purchase, hold or deal in real estate, although a Fund may
                  purchase and sell securities that are secured by real estate
                  or interests therein, securities of real estate investment
                  trusts and mortgage-related securities and may hold and sell
                  real estate acquired by a Fund as a result of the ownership of
                  securities.

            (7)   Invest in commodities or commodity contracts, except that the
                  Fund may invest in currency and financial instruments and
                  contracts that are commodities or commodity contracts.

            (8)   Issue senior securities to the extent such issuance would
                  violate applicable law.

of Goldman Sachs, a fee for each Trustee meeting attended and an annual fee.
Such Trustees are also reimbursed for travel expenses incurred in connection
with attending such meetings.

officers, partners, directors or employees (including rehired employees and

      As stated in the Funds' Prospectus, GSFM, One New York Plaza, New York,

Broad Street, New York, New York, serves as Investment Adviser to CORE U.S.

separate operating division of Goldman Sachs, serves as Investment Adviser to
Balanced, Growth and Income, CORE Large Cap Value, CORE Large Cap Growth, CORE

133 Petersborough Court, London, England EC4A 2BB serves as Investment Adviser
to International Equity, European Equity, Japanese Equity, International Small
Cap, Emerging Markets Equity and Asia Growth Funds. GSAMI is also an affiliate
of Goldman Sachs. See "Service Providers" in the Funds' Prospectus for a
description of the applicable Investment Adviser's duties to the Funds.

      The Goldman Sachs Group, L.P., which controls the Funds' investment
advisers, announced that it will pursue an initial public offering of the firm
in the late spring or early summer of 1999. Simultaneously with the offering,
the Goldman Sachs Group, L.P. will merge into The Goldman Sachs Group, Inc.

      Founded in 1869, Goldman Sachs is among the oldest and largest investment
banking firms in the United States. Goldman Sachs is a leader in developing
portfolio strategies and in many fields of investing and financing,
participating in financial markets worldwide and serving individuals,
institutions, corporations and governments. Goldman Sachs is also among the
principal market sources for current and thorough information on companies,
industrial sectors, markets, economies and currencies, and trades and makes
markets in a wide range of equity and debt securities 24-hours a day. The firm
is headquartered in New York and has offices throughout the United States and in
Beijing, Frankfurt, George Town, Hong Kong, London, Madrid, Mexico City, Milan,
Montreal, Osaka, Paris, Sao Paulo, Seoul, Shanghai, Singapore, Sydney, Taipei,
Tokyo, Toronto, Vancouver and Zurich. It has trading professionals throughout
the United States, as well as in London, Tokyo, Hong Kong and Singapore. The
active participation of Goldman Sachs in the world's financial markets enhances
its ability to identify attractive investments. Goldman Sachs has agreed to
permit the Funds to use the name "Goldman Sachs" or a derivative thereof as part
of each Fund's name for as long as a Fund's Management Agreement is in effect.

      The Investment Advisers are able to draw on the substantial research and
market expertise of Goldman Sachs, whose investment research effort is one of
the largest in the industry. The Goldman Sachs Global Investment Research
Department covers approximately


                                      B-60
<PAGE>
 
2,200 companies, including approximately 1,000 U.S. corporations in 60
industries. The in-depth information and analyses generated by Goldman Sachs'
research analysts are available to the Investment Advisers.

      For more than a decade, Goldman Sachs has been among the top-ranked firms
in Institutional Investor's annual "All-America Research Team" survey. In
addition, many of Goldman Sachs' economists, securities analysts, portfolio
strategists and credit analysts have consistently been highly ranked in
respected industry surveys conducted in the U.S. and abroad. Goldman Sachs is
also among the leading investment firms using quantitative analytics (now used
by a growing number of investors) to structure and evaluate portfolios.

      In managing the Funds, the Investment Advisers have access to Goldman
Sachs' economics research. The Economics Research Department, based in London,
conducts economic, financial and currency markets research which analyzes
economic trends and interest and exchange rate movement worldwide. The Economics
Research Department tracks factors such as inflation and money supply figures,
balance of trade figures, economic growth, commodity prices, monetary and fiscal
policies, and political events that can influence interest rates and currency
trends. The success of Goldman Sachs' international research team has brought
wide recognition to its members. The team has earned top rankings in various
external surveys such as Extel, Institutional Investor and Reuters. These
rankings acknowledge the achievements of the firm's economists, strategists and
equity analysts.

      In allocating assets among foreign countries and currencies for the Funds
which can invest in foreign securities (in particular, the CORE International
Equity, International Equity, International Small Cap, Emerging Markets Equity
and Asia Growth Funds), the Investment Advisers will have access to the Global
Asset Allocation Model. The model is based on the observation that the prices of
all financial assets, including foreign currencies, will adjust until investors
globally are comfortable holding the pool of outstanding assets. Using the
model, the Investment Advisers will estimate the total returns from each
currency sector which are consistent with the average investor holding a
portfolio equal to the market capitalization of the financial assets among those
currency sectors. These estimated equilibrium returns are then combined with the
expectations of Goldman Sachs' research professionals to produce an optimal
currency and asset allocation for the level of risk suitable for a Fund given
its investment objectives and criteria.

      The Management Agreements provide that GSAM, GSFM and GSAMI, in their
capacity as Investment Advisers, may render similar services to others as long
as the services under the Management Agreements are not impaired thereby. The
Strategic Growth, Growth Opportunities, CORE Large Cap Value, European Equity,
Japanese Equity and International Small Cap Funds' management agreements were
initially approved by the Trustees, including a majority of the non-interested
Trustees (as defined below) who are not parties to the Management Agreement on
April 28, 1999, April 28, 1999, November 3, 1998, July 22, 1998, April 23, 1998
and April 23, 1998, respectively. The CORE Small Cap Equity, CORE International
Equity and Real Estate Securities Funds' Management Agreements were initially
approved by the Trustees, including a majority of the non-interested Trustees
(as defined below) who are not parties to the Management Agreements, on July 22,
1997. The CORE Large Cap


                                      B-61

Growth and Emerging Markets Equity Funds' Management Agreements were initially
approved by the Trustees, including a majority of the non-interested Trustees
(as defined below) who are not parties to the management agreements, on April
23, 1997. The Funds' Management Agreements were most recently approved by the
Trustees, including a majority of the Trustees who are not parties to the
management agreements or "interested persons" (as such term is defined in the
Act) of any party thereto (the "non-interested Trustees"), on April 27, 1999.
These arrangements were most recently approved by the shareholders of each Fund
(other than Strategic Growth, Growth Opportunities, CORE Large Cap Value, CORE
Large Cap Growth, CORE Small Cap Equity, CORE International Equity, Emerging
Markets Equity, Real Estate Securities, Japanese Equity, International Small Cap
and European Equity Funds) on April 21, 1997. The sole shareholder of the
Strategic Growth, Growth Opportunities, CORE Large Cap Value, CORE Large Cap
Growth, CORE Small Cap Equity, CORE International Equity, Emerging Markets
Equity, Real Estate Securities, Japanese Equity, International Small Cap and
European Equity Funds approved these arrangements on April 29, 1999, April 29,

28, 1997, July 21, 1997, April 23, 1998, April 23, 1998 and July 22, 1998,
respectively. Each Management Agreement will remain in effect until June 30,
2000 and will continue in effect with respect to the applicable Fund from year
to year thereafter provided such continuance is specifically approved at least
annually by (a) the vote of a majority of the outstanding voting securities of
such Fund or a majority of the Trustees of the Trust, and (b) the vote of a
majority of the non-interested Trustees of the Trust, cast in person at a
meeting called for the purpose of voting on such approval.

      Each Management Agreement will terminate automatically if assigned (as
defined in the Act). Each Management Agreement is also terminable at any time
without penalty by the Trustees of the Trust or by vote of a majority of the
outstanding voting securities of the Fund on 60 days' written notice to the
applicable Investment Adviser and by the Investment Adviser on 60 days' written
notice to the Trust.

      Pursuant to the Management Agreements the Investment Advisers are entitled
to receive the fees set forth below, payable monthly based on such Fund's
average daily net assets. In addition, as of the date of this Additional
Statement the Investment Advisers were voluntarily limiting their management
fees for certain funds to the annual rates also listed below:

      Prior to May 1, 1997, the Funds then in operation had separate investment
advisory (and subadvisory, in the case of the International Equity Fund) and
administration agreements. Effective May 1, 1997, the services under such
agreements were combined in the management agreement. The services required to
be performed for the Funds and the combined advisory (and subadvisory, in the
case of the International Equity Fund) and administration fees payable by the
Funds under the former advisory (and subadvisory, in the case of the
International Equity Fund) and administration agreements are identical to the
services and fees under the management agreement.

      For the last three fiscal years the amounts of the combined investment
advisory (and subadvisory, in the case of the International Equity Fund) and
administration fees incurred by each Fund then in existence were as follows
(with and without the fee limitations that were then in effect):

1 The CORE Large Cap Value, CORE Large Cap Growth, CORE Small Cap Equity, CORE
International Equity, European Equity, Japanese Equity, International Small Cap
and Emerging Markets Equity Funds commenced operations on December 31, 1998, May
1, 1997, August 15, 1997, August 15, 1997, October 1, 1998, May 1, 1998, May 1,
1998 and December 15, 1997, respectively.

2 During the fiscal years ended January 31, 1999, 1998 and 1997, no Shares of
the Strategic Growth or Growth Opportunities Funds had been offered.

      During the period July 27, 1998 (commencement of operations) through
December 31, 1998, the Real Estate Securities Fund incurred $82,560 and $82,560
(with and without fee limitations then in effect, respectively) in combined
investment advisory and administration fees.

      Under the Management Agreement, each Investment Adviser also: (i)
supervises all non-advisory operations of each Fund that it advises; (ii)
provides personnel to perform such executive, administrative and clerical
services as are reasonably necessary to provide effective administration of each
Fund; (iii) arranges for at each Fund's expense: (a) the preparation of all
required tax returns, (b) the preparation and submission of reports to existing
shareholders, (c) the periodic updating of prospectuses and statements of
additional information and (d) the preparation of reports to be filed with the
SEC and other regulatory authorities; (iv) maintains each Fund's records; and
(v) provides office space and all necessary office equipment and services.

      Activities of Goldman Sachs and Its Affiliates and Other Accounts Managed
by Goldman Sachs. The involvement of the Investment Advisers and Goldman Sachs
and their affiliates in the management of, or their interest in, other accounts
and other activities of Goldman Sachs may present conflicts of interest with
respect to the Funds or impede their investment activities.

      Goldman Sachs and its affiliates, including, without limitation, the
Investment Advisers and their advisory affiliates, have proprietary interests
in, and may manage or advise with respect to, accounts or funds (including
separate accounts and other funds and collective investment vehicles) which have
investment objectives similar to those of the Funds and/or which engage in
transactions in the same types of securities, currencies and instruments as the
Funds. Goldman Sachs and its affiliates are major participants in the global
currency, equities, swap and fixed-income markets, in each case both on a
proprietary basis and for the accounts of customers. As such, Goldman Sachs and
its affiliates are actively engaged in transactions in the same securities,
currencies and instruments in which the Funds invest. Such activities could
affect the prices and availability of the securities, currencies and instruments
in which the Funds will invest, which could have an adverse impact on each
Fund's performance. Such transactions, particularly in respect of proprietary
accounts or customer accounts other than those included in the Investment
Advisers' and their advisory affiliates' asset management activities, will be
executed independently of the Funds' transactions and thus at prices or rates
that may be more or less favorable. When the Investment Advisers and their
advisory affiliates seek to purchase or sell the same assets for their managed
accounts, including the Funds, the assets actually purchased or sold may be
allocated among the accounts on a basis determined in its good faith discretion
to be equitable. In some cases, this system may adversely affect the size or the
price of the assets purchased or sold for the Funds.


                                      B-64
<PAGE>
 
      From time to time, the Funds' activities may be restricted because of
regulatory restrictions applicable to Goldman Sachs and its affiliates, and/or
their internal policies designed to comply with such restrictions. As a result,
there may be periods, for example, when the Investment Advisers and/or their
affiliates will not initiate or recommend certain types of transactions in
certain securities or instruments with respect to which the Investment Advisers
and/or their affiliates are performing services or when position limits have
been reached.

      In connection with their management of the Funds, the Investment Advisers
may have access to certain fundamental analysis and proprietary technical models
developed by Goldman Sachs and other affiliates. The Investment Advisers will
not be under any obligation, however, to effect transactions on behalf of the
Funds in accordance with such analysis and models. In addition, neither Goldman
Sachs nor any of its affiliates will have any obligation to make available any
information regarding their proprietary activities or strategies, or the
activities or strategies used for other accounts managed by them, for the
benefit of the management of the Funds and it is not anticipated that the
Investment Advisers will have access to such information for the purpose of
managing the Funds. The proprietary activities or portfolio strategies of
Goldman Sachs and its affiliates or the activities or strategies used for
accounts managed by them or other customer accounts could conflict with the
transactions and strategies employed by the Investment Advisers in managing the
Funds.

      The results of each Fund's investment activities may differ significantly
from the results achieved by the Investment Advisers and their affiliates for
their proprietary accounts or accounts (including investment companies or
collective investment vehicles) managed or advised by them. It is possible that
Goldman Sachs and its affiliates and such other accounts will achieve investment
results which are substantially more or less favorable than the results achieved
by a Fund. Moreover, it is possible that a Fund will sustain losses during
periods in which Goldman Sachs and its affiliates achieve significant profits on
their trading for proprietary or other accounts. The opposite result is also
possible.

      The investment activities of Goldman Sachs and its affiliates for their
proprietary accounts and accounts under their management may also limit the
investment opportunities for the Fund in certain emerging markets in which
limitations are imposed upon the aggregate amount of investment, in the
aggregate or individual issuers, by affiliated foreign investors.

      An investment policy committee which may include partners of Goldman Sachs
and its affiliates may develop general policies regarding a Fund's activities
but will not be involved in the day-to-day management of such Fund. In such
instances, those individuals may, as a result, obtain information regarding the
Fund's proposed investment activities which is not generally available to the
public. In addition, by virtue of their affiliation with Goldman Sachs, any such
member of an investment policy committee will have direct or indirect interests
in the activities of Goldman Sachs and its affiliates in securities and
investments similar to those in which the Fund invests.

      In addition, certain principals and certain of the employees of the
Investment Advisers are also principals or employees of Goldman Sachs or their
affiliated entities. As a result, the performance by these principals and
employees of their obligations to such other entities may be a consideration of
which investors in the Funds should be aware.


                                      B-65
<PAGE>
 
      Each Investment Adviser may enter into transactions and invest in
currencies or instruments on behalf of a Fund in which customers of Goldman
Sachs serve as the counterparty, principal or issuer. In such cases, such
party's interests in the transaction will be adverse to the interests of a Fund,
and such party may have no incentive to assure that the Funds obtain the best
possible prices or terms in connection with the transactions. Goldman Sachs and
its affiliates may also create, write or issue derivative instruments for
customers of Goldman Sachs or its affiliates, the underlying securities or
instruments of which may be those in which a Fund invests or which may be based
on the performance of a Fund. The Funds may, subject to applicable law, purchase
investments which are the subject of an underwriting or other distribution by
Goldman Sachs or its affiliates and may also enter transactions with other
clients of Goldman Sachs or its affiliates where such other clients have
interests adverse to those of the Funds. At times, these activities may cause
departments of the Firm to give advice to clients that may cause these clients
to take actions adverse to the interests of the client. To the extent affiliated
transactions are permitted, the Funds will deal with Goldman Sachs and its
affiliates on an arms-length basis.

      Each Fund will be required to establish business relationships with its
counterparties based on the Fund's own credit standing. Neither Goldman Sachs
nor its affiliates will have any obligation to allow their credit to be used in
connection with a Fund's establishment of its business relationships, nor is it
expected that a Fund's counterparties will rely on the credit of Goldman Sachs
or any of its affiliates in evaluating the Fund's creditworthiness.

      From time to time, Goldman Sachs or any of its affiliates may, but is not
required to, purchase and hold shares of a Fund in order to increase the assets
of the Fund. Increasing a Fund's assets may enhance investment flexibility and
diversification and may contribute to economies of scale that tend to reduce the
Fund's expense ratio. Goldman Sachs reserves the right to redeem at any time
some or all of the shares of a Fund acquired for its own account. A large
redemption of shares of a Fund by Goldman Sachs could significantly reduce the
asset size of the Fund, which might have an adverse effect on the Fund's
investment flexibility, portfolio diversification and expense ratio. Goldman
Sachs will consider the effect of redemptions on a Fund and other shareholders
in deciding whether to redeem its shares.

      It is possible that a Fund's holdings will include securities of entities
for which Goldman Sachs performs investment banking services as well as
securities of entities in which Goldman Sachs makes a market. From time to time,
Goldman Sachs' activities may limit the Funds' flexibility in purchases and
sales of securities. When Goldman Sachs is engaged in an underwriting or other
distribution of securities of an entity, the Investment Advisers may be
prohibited from purchasing or recommending the purchase of certain securities of
that entity for the Funds.

Distributor and Transfer Agent

      Goldman Sachs serves as the exclusive distributor of shares of the Funds
pursuant to a "best efforts" arrangement as provided by a distribution agreement
with the Trust on behalf of each Fund. Shares of the Funds are offered and sold
on a continuous basis by Goldman Sachs, acting as agent. Pursuant to the
distribution agreement, after the Prospectus and periodic reports have been
prepared, set in type and mailed to shareholders, Goldman Sachs will pay for the
printing and distribution of


                                      B-66
<PAGE>
 
copies thereof used in connection with the offering to prospective investors.
Goldman Sachs will also pay for other supplementary sales literature and
advertising costs. Goldman Sachs may enter into sales agreements with certain
investment dealers and other financial service firms (the "Authorized Dealers")
to solicit subscriptions for shares of the Funds. Goldman Sachs receives a
portion of the sales charge imposed on the sale, in the case of Class A Shares,
or redemption in the case of Class B and Class C Shares (and in certain cases,
Class A Shares), of such Fund shares. No Class C Shares were outstanding during
the fiscal year ended January 31, 1997.

      Goldman Sachs retained approximately the following combined commissions on
sales of Class A, Class B and Class C Shares during the following periods:

      The Trust's distribution and transfer agency agreements each provide that
Goldman Sachs may render similar services to others so long as the services
Goldman Sachs provides thereunder are not impaired thereby. Such agreements also
provide that the Trust will indemnify Goldman Sachs against certain liabilities.

Expenses

      The Trust, on behalf of each Fund, is responsible for the payment of each
Fund's respective expenses. The expenses include, without limitation, the fees
payable to the Investment Advisers, service fees paid to Service Organizations,
the fees and expenses of the Trust's custodian and subcustodians, transfer agent
fees, brokerage fees and commissions, filing fees for the registration or
qualification of the Trust's shares under federal or state securities laws,
expenses of the organization of the Trust, fees and expenses incurred by the
Trust in connection with membership in investment company organizations, taxes,
interest, costs of liability insurance, fidelity bonds or indemnification, any
costs, expenses or losses arising out of any liability of, or claim for damages
or other relief asserted against, the Trust for violation of any law, legal and
auditing fees and expenses (including the cost of legal and certain accounting
services rendered by employees of GSAM, GSAMI and Goldman Sachs with respect to
the Trust), expenses of preparing and setting in type prospectuses, statements
of additional information, proxy material, reports and notices and the printing
and distributing of the same to the Trust's shareholders and regulatory
authorities, any expenses assumed by a Fund pursuant to its distribution and
service plans, compensation and expenses of its "non-interested" Trustees and
extraordinary expenses, if any, incurred by the Trust. Except for fees under any
distribution and service plans applicable to a particular class and transfer
agency fees, all Fund expenses are borne on a non-class specific basis.

      The imposition of the Investment Adviser's fee, as well as other operating
expenses, will have the effect of reducing the total return to investors. From
time to time, the Investment Adviser may waive receipt of is fees and/or
voluntarily assume certain expenses of a Fund, which would have the effect of
lowering that Fund's overall expense ratio and increasing total return to
investors at the time such amounts are waived or assumed, as the case may be.

      The Investment Advisers voluntarily have agreed to reduce or limit certain
"Other Expenses" (excluding management, distribution and service fees, transfer
agency fees, service share fees, taxes, interest, brokerage, and litigation,
indemnification and other extraordinary expenses) for the following Funds to the
extent such expenses exceed the following percentage of average daily net
assets:

      Such reductions or limits, if any, are calculated monthly on a cumulative
basis and may be discontinued or modified by the applicable Investment Adviser
in its discretion at any time.

      Fees and expenses of legal counsel, registering shares of a Fund, holding
meetings and communicating with shareholders may include an allocable portion of
the cost of maintaining an internal legal and compliance department. Each Fund
may also bear an allocable portion of the applicable Investment Adviser's costs
of performing certain accounting services not being provided by a Fund's
Custodian.

      During the period July 27, 1998 (commencement of operations) through
December 31, 1998, the amount of certain of the Real Estate Securities Fund's
"Other Expenses" that was reduced or otherwise limited was $151,328 under the
expense limitations that were then in effect.

Custodian and Sub-Custodians

      State Street, P.O. Box 1713, Boston, Massachusetts 02105, is the custodian
of the Trust's portfolio securities and cash. State Street also maintains the
Trust's accounting records. State Street may appoint domestic and foreign
sub-custodians from time to time to hold certain securities purchased by the
Trust and to hold cash for the Trust.

Independent Public Accountants

      Arthur Andersen LLP, independent public accountants, 225 Franklin Street,
Boston, Massachusetts 02110, have been selected as auditors of the Trust. In
addition to audit services, Arthur Andersen LLP prepares the Trust's federal and
state tax returns, and provides consultation and assistance on accounting,
internal control and related matters.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

      The Investment Advisers are responsible for decisions to buy and sell
securities for the Funds, the selection of brokers and dealers to effect the
transactions and the negotiation of brokerage commissions, if any. Purchases and
sales of securities on a securities exchange are effected through brokers who
charge a commission for their services. Orders may be directed to any broker
including, to the extent and in the manner permitted by applicable law, Goldman
Sachs.

      In the over-the-counter market, securities are generally traded on a "net"
basis with dealers acting as principal for their own accounts without a stated
commission, although the price of a security usually includes a profit to the
dealer. In underwritten offerings, securities are purchased at a fixed price
which includes an amount of compensation to the underwriter, generally referred
to as the underwriter's concession or discount. On occasion, certain money
market instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid.

      In placing orders for portfolio securities of a Fund, the Investment
Advisers are generally required to give primary consideration to obtaining the
most favorable execution and net price available. This means that an Investment
Adviser will seek to execute each transaction at a price and commission, if any,
which provides the most favorable total cost or proceeds reasonably attainable
in the circumstances. As permitted by Section 28(e) of the Securities Exchange
Act of 1934, the Fund may pay a broker which provides brokerage and research
services to the Fund an amount of disclosed commission in excess of the
commission which another broker would have charged for effecting that
transaction. Such practice is subject to a good faith determination that such
commission is reasonable in light of the services provided and to such policies
as the Trustees may adopt from time to time. While the Investment Advisers
generally seek reasonably competitive spreads or commissions, a Fund will not
necessarily be paying the lowest spread or commission available. Within the
framework of this policy, the Investment Advisers will consider research and


                                      B-73
<PAGE>
 
investment services provided by brokers or dealers who effect or are parties to
portfolio transactions of a Fund, the Investment Advisers and their affiliates,
or their other clients. Such research and investment services are those which
brokerage houses customarily provide to institutional investors and include
research reports on particular industries and companies, economic surveys and
analyses, recommendations as to specific securities and other products or
services (e.g., quotation equipment and computer related costs and expenses),
advice concerning the value of securities, the advisability of investing in,
purchasing or selling securities, the availability of securities or the
purchasers or sellers of securities, furnishing analyses and reports concerning
issuers, industries, securities, economic factors and trends, portfolio strategy
and performance of accounts, effecting securities transactions and performing
functions incidental thereto (such as clearance and settlement) and providing
lawful and appropriate assistance to the Investment Advisers in the performance
of their decision-making responsibilities. Such services are used by the
Investment Advisers in connection with all of their investment activities, and
some of such services obtained in connection with the execution of transactions
for a Fund may be used in managing other investment accounts. Conversely,
brokers furnishing such services may be selected for the execution of
transactions of such other accounts, whose aggregate assets are far larger than
those of a Fund, and the services furnished by such brokers may be used by the
Investment Advisers in providing management services for the Trust.

      In circumstances where two or more broker-dealers offer comparable prices
and execution capability, preference may be given to a broker-dealer which has
sold shares of the Fund as well as shares of other investment companies or
accounts managed by the Investment Advisers. This policy does not imply a
commitment to execute all portfolio transactions through all broker-dealers that
sell shares of the Fund.

      On occasions when an Investment Adviser deems the purchase or sale of a
security to be in the best interest of a Fund as well as its other customers
(including any other fund or other investment company or advisory account for
which such Investment Adviser acts as investment adviser or sub-investment
adviser), the Investment Adviser, to the extent permitted by applicable laws and
regulations, may aggregate the securities to be sold or purchased for the Fund
with those to be sold or purchased for such other customers in order to obtain
the best net price and most favorable execution under the circumstances. In such
event, allocation of the securities so purchased or sold, as well as the
expenses incurred in the transaction, will be made by the applicable Investment
Adviser in the manner it considers to be equitable and consistent with its
fiduciary obligations to such Fund and such other customers. In some instances,
this procedure may adversely affect the price and size of the position
obtainable for a Fund.

      Commission rates in the U.S. are established pursuant to negotiations with
the broker based on the quality and quantity of execution services provided by
the broker in the light of generally prevailing rates. The allocation of orders
among brokers and the commission rates paid are reviewed periodically by the
Trustees.

      Subject to the above considerations, the Investment Advisers may use
Goldman Sachs as a broker for a Fund. In order for Goldman Sachs to effect any
portfolio transactions for each Fund, the commissions, fees or other
remuneration received by Goldman Sachs must be reasonable and fair compared to
the commissions, fees or other remuneration paid to other brokers in connection


                                      B-74
<PAGE>
 
with comparable transactions involving similar securities being purchased or
sold on a securities exchange during a comparable period of time. This standard
would allow Goldman Sachs to receive no more than the remuneration which would
be expected to be received by an unaffiliated broker in a commensurate
arm's-length transaction. Furthermore, the Trustees, including a majority of the
Trustees who are not "interested" Trustees, have adopted procedures which are
reasonably designed to provide that any commissions, fees or other remuneration
paid to Goldman Sachs are consistent with the foregoing standard. Brokerage
transactions with Goldman Sachs are also subject to such fiduciary standards as
may be imposed upon Goldman Sachs by applicable law.

                                 NET ASSET VALUE

      Under the Act, the Trustees are responsible for determining in good faith
the fair value of securities of each Fund. In accordance with procedures adopted
by the Trustees, the net value per share of each class of each Fund is
calculated by determining the value of the net assets attributed to each class
of that Fund and dividing by the number of outstanding shares of that class. All
securities are valued as of the close of regular trading on the New York Stock
Exchange (normally, but not always, 4:00 p.m. New York time) on each Business
Day. The term "Business Day" means any day the New York Stock Exchange is open
for trading, which is Monday through Friday except for holidays. The New York
Stock Exchange is closed on the following holidays: New Year's Day, Martin
Luther King, Jr. Day, Presidents' Day (observed), Good Friday, Memorial Day
(observed), Independence Day (observed), Labor Day, Thanksgiving Day and
Christmas Day (observed).

      In the event that the New York Stock Exchange or the national securities
exchange on which stock options are traded adopt different trading hours on
either a permanent or temporary basis, the Trustees will reconsider the time at
which net asset value is computed. In addition, each Fund may compute its net
asset value as of any time permitted pursuant to any exemption, order or
statement of the SEC or its staff.

      Portfolio securities of the Fund for which accurate market quotations are
available are valued as follows: (a) securities listed on any U.S. or foreign
stock exchange or on the National Association of Securities Dealers Automated
Quotations System ("NASDAQ") will be valued at the last sale price on the
exchange or system in which they are principally traded on the valuation date.
If there is no sale on the valuation day, securities traded will be valued at
the closing bid price, or if a closing bid price is not available, at either the
exchange or system-defined close price on the exchange or system in which such
securities are principally traded. If the relevant exchange or system has not
closed by the above-mentioned time for determining the Funds net asset value,
the


                                      B-81
<PAGE>
 
securities will be valued at the last sale price, or if not available at the bid
price at the time the net asset value is determined; (b) over-the-counter
securities not quoted on NASDAQ will be valued at the last sale price on the
valuation day or, if no sale occurs, at the last bid price at the time net asset
value is determined; (c) equity securities for which no prices are obtained
under section (a) or (b) including those for which a pricing service supplies no
exchange quotation or a quotation that is believed by the portfolio
manager/trader to be inaccurate, will be valued at their fair value in
accordance with procedures approved by the Board of Trustees; (d) fixed-income
securities with a remaining maturity of 60 days or more for which accurate
market quotations are readily available will normally be valued according to
dealer-supplied bid quotations or bid quotations from a recognized pricing
service (e.g., Merrill Lynch, J.J. Kenny, Muller Data Corp., Bloomberg, EJV,
Reuters or Standard & Poor's); (e) fixed-income securities for which accurate
market quotations are not readily available are valued by the Investment
Advisers based on valuation models that take into account spread and daily yield
changes on government securities in the appropriate market (i.e., matrix
pricing); (f) debt securities with a remaining maturity of 60 days or less are
valued by the Investment Adviser at amortized cost, which the Trustees have
determined to approximate fair value; and (g) all other instruments, including
those for which a pricing service supplies no exchange quotation or a quotation
that is believed by the portfolio manager/trader to be inaccurate, will be
valued at fair value in accordance with the valuation procedures approved by the
Board of Trustees.

      The value of all assets and liabilities expressed in foreign currencies
will be converted into U.S. dollar values at current exchange rates of such
currencies against U.S. dollars last quoted by any major bank. If such
quotations are not available, the rate of exchange will be determined in good
faith by or under procedures established by the Board of Trustees.

      Generally, trading in securities on European and Far Eastern securities
exchanges and on over-the-counter markets is substantially completed at various
times prior to the close of business on each Business Day in New York (i.e., a
day on which the New York Stock Exchange is open for trading). In addition,
European or Far Eastern securities trading generally or in a particular country
or countries may not take place on all Business Days in New York. Furthermore,
trading takes place in various foreign markets on days which are not Business
Days in New York and days on which the Funds' net asset values are not
calculated. Such calculation does not take place contemporaneously with the
determination of the prices of the majority of the portfolio securities used in
such calculation. The impact of events that occur after the publication of
market quotations used by a Fund to price its securities but before the close of
regular trading on the New York Stock Exchange will normally not be reflected in
a Fund's next determined NAV unless the Trust, in its discretion, makes an
adjustment in light of the nature and materiality of the event, its effect on
Fund operations and other relevant factors.

      The proceeds received by each Fund and each other series of the Trust from
the issue or sale of its shares, and all net investment income, realized and
unrealized gain and proceeds thereof, subject only to the rights of creditors,
will be specifically allocated to such Fund and constitute the underlying assets
of that Fund or series. The underlying assets of each Fund will be segregated on
the books of account, and will be charged with the liabilities in respect of
such Fund and with a share of the general liabilities of the Trust. Expenses of
the Trust with respect to the Funds and the


                                      B-82
<PAGE>
 
other series of the Trust are generally allocated in proportion to the net asset
values of the respective Funds or series except where allocations of direct
expenses can otherwise be fairly made.

                             PERFORMANCE INFORMATION

      Each Fund may from time to time quote or otherwise use yield and total
return information in advertisements, shareholder reports or sales literature.
Average annual total return and yield are computed pursuant to formulas
specified by the SEC.

      Thirty-day yield is derived by dividing net investment income per share
earned during the period by the maximum public offering price per share on the
last day of such period. The results are compounded on a bond equivalent
(semi-annual) basis and then annualized. Net investment income per share is
equal to the dividends and interest earned during the period, reduced by accrued
expenses for the period. The calculation of net investment income for these
purposes may differ from the net investment income determined for accounting
purposes.

      Distribution rate for a specified period is calculated by annualizing
distributions of net investment income for such period and dividing this amount
by the net asset value per share or maximum public offering price on the last
day of the period.

      Average annual total return for a specified period is derived by
calculating the actual dollar amount of the investment return on a $1,000
investment made at the maximum public offering price at the beginning of the
period, and then calculating the annual compounded rate of return which would
produce that amount, assuming a redemption at the end of the period. This
calculation assumes a complete redemption of the investment. It also assumes
that all dividends and distributions are reinvested at net asset value on the
reinvestment dates during the period.

      Year-by-year total return and cumulative total return for a specified
period are each derived by calculating the percentage rate required to make a
$1,000 investment (made at the maximum public offering price with all
distributions reinvested) at the beginning of such period equal to the actual
total value of such investment at the end of such period. The table set forth
below indicates the total return (capital changes plus reinvestment of all
distributions) on a hypothetical investment of $1,000 in a Fund for the periods
indicated.

      Total return calculations for Class A Shares reflect the effect of paying
the maximum initial sales charge. Investment at a lower sales charge would
result in higher performance figures. Total return calculations for Class B and
Class C Shares reflect deduction of the applicable CDSC imposed upon redemption
of Class B and Class C Shares held for the applicable period. Each Fund may also
from time to time advertise total return on a cumulative, average, year-by-year
or other basis for various specified periods by means of quotations, charts
graphs or schedules. In addition, each Fund may furnish total return
calculations based on investments at various sales charge levels or at NAV. Any
performance information which is based on a Fund's NAV per Share would be
reduced if any applicable sales charge were taken into account. In addition to
the above, each Fund may from time to time advertise its performance relative to
certain averages, performance rankings, indices, other information


                                      B-83
<PAGE>
 
prepared by recognized mutual fund statistical services and investments for
which reliable performance information is available. The Funds' performance
quotations do not reflect any fees charged by an Authorized Dealer, Service
Organization or other financial intermediary to its customer accounts in
connection with investments in the Funds.

      Occasionally, statistics may be used to specify Fund volatility or risk.
Measures of volatility or risk are generally used to compare a Fund's net asset
value or performance relative to a market index. One measure of volatility is
beta. Beta is the volatility of a Fund relative to the total market. A beta of
more than 1.00 indicates volatility greater than the market, and a beta of less
than 1.00 indicates volatility less than the market. Another measure of
volatility or risk is standard deviation. Standard deviation is used to measure
variability of net asset value or total return around an average, over a
specified period of time. The premise is that greater volatility connotes
greater risk undertaken in achieving performance.

      From time to time the Trust may publish an indication of a Fund's past
performance as measured by independent sources such as (but not limited to)
Lipper Analytical Services, Inc., Morningstar Mutual Funds, Weisenberger
Investment Companies Service, Donoghue's Money Fund Report, Micropal, Barron's,
Business Week, Consumer's Digest, Consumer's Report, Investors Business Daily,

Financial World, Forbes, Fortune, Money, Personal Investor, Sylvia Porter's
Personal Finance and The Wall Street Journal. The Trust may also advertise
information which has been provided to the NASD for publication in regional and
local newspapers. In addition, the Trust may from time to time advertise a
Fund's performance relative to certain indices and benchmark investments,
including: (a) the Lipper Analytical Services, Inc. Mutual Fund Performance
Analysis, Fixed-Income Analysis and Mutual Fund Indices (which measure total
return and average current yield for the mutual fund industry and rank mutual
fund performance); (b) the CDA Mutual Fund Report published by CDA Investment

averages are generally unmanaged and the items included in the calculations of
such indices and averages may not be identical to the formulas used by a Fund to
calculate its performance figures.

      In addition, the Trust may from time to time include rankings of Goldman,
Sachs & Co.'s research department by publications such as the Institutional
Investor and the Wall Street Journal in advertisements.

      The CORE Large Cap Growth Fund commenced operations on May 1, 1997. The
performance information shown below for periods before that date is for a
predecessor separate account managed by the Investment Adviser which converted
into Class A Shares as of the commencement date. The performance record of the
separate account quoted by the Fund have been adjusted downward based on the
expenses applicable to Class A Shares (the class into which the separate account
transferred) to reflect the expenses expected to be incurred by the Fund during
its initial year of operation. These expenses include any sales charges and
asset-based charges (i.e., fees under Distribution and Service Plans) imposed
and other operating expenses. Total return quotations are calculated pursuant to
the methodology prescribed by the SEC for standardized performance calculations.
Prior to May 1, 1997, the separate account was a separate investment advisory
account under discretionary management by the Investment Adviser and had
substantially similar investment objectives, policies and strategies as the
Fund. Unlike the Fund, the separate account was not registered as an investment
company under the Act and therefore was not subject to certain investment
restrictions and operational requirements that are imposed on investment
companies by the Act. If the separate account had been registered as an
investment company under the Act, the separate account's performance may have
been adversely affected by such restrictions and requirements. On May 1, 1997,
the separate account transferred a portion of its assets to the Fund in exchange
for Fund shares. The performance record of each other class has been linked to
the performance of the separate account (based on Class A expenses) and the
Class A performance for any periods prior to commencement of operations of a
class of shares.

      The Service Shares of Balanced, Capital Growth, Small Cap Value, Growth
and Income, CORE U.S. Equity, CORE Large Cap Growth and International Equity
Funds commenced operations on August 15, 1997, August 15, 1997, August 15, 1997,
March 6, 1996, June 7, 1996, May 1, 1997 and March 6, 1996, respectively. The
Service Shares of these Funds had no operating or performance history prior
thereto. However, in accordance with interpretive positions expressed


                                      B-86
<PAGE>
 
by the staff of the SEC, each of these Funds has adopted the performance records
of its respective Class A Shares from that class's inception date (October 12,
1994, April 20, 1990, October 22, 1992, February 5, 1993, May 24, 1991, May 1,
1997 and December 1, 1992 respectively) to the inception dates of Service Shares
stated above. Quotations of performance data of these Funds relating to this
period include the performance record of the applicable Class A Shares
(excluding the impact of any applicable front-end sales charge). The performance
records of the applicable Class A Shares reflect the expenses incurred by the
Funds. These expenses include asset-based charges (i.e., fees under Distribution
and Service Plans) and other operating expenses. Total return quotations are
calculated pursuant to SEC-approved methodology.

- ----------

All returns are average annual total returns.

* Represents an aggregate total return (not annualized) since this class has not
completed a full twelve months of operations.

** Total return reflects a maximum initial sales charge of 5.5% for Class A
Shares, the assumed deferred sales charge for Class B Shares (5% maximum
declining to 0% after six years) and the assumed deferred sales charge for Class
C Shares (1% if redeemed within 12 months of purchase). Prior to the date of
this Additional Statement, no shares of the Strategic Growth or Growth
Opportunities Funds had been offered.

      From time to time, advertisements or information may include a discussion
of certain attributes or benefits to be derived by an investment in the Fund.
Such advertisements or information may include symbols, headlines or other
material which highlight or summarize the information discussed in more detail
in the communication.

      The Trust may from time to time summarize the substance of discussions
contained in shareholder reports in advertisements and publish the Investment
Adviser's views as to markets, the rationale for a Fund's investments and
discussions of a Fund's current asset allocation.

      In addition, from time to time, advertisements or information may include
a discussion of asset allocation models developed by GSAM and/or its affiliates,
certain attributes or benefits to be derived from asset allocation strategies
and the Goldman Sachs mutual funds that may be offered as investment options for
the strategic asset allocations. Such advertisements and information may also
include GSAM's current economic outlook and domestic and international market
views to suggest periodic tactical modifications to current asset allocation
strategies. Such advertisements and information may include other materials
which highlight or summarize the services provided in support of an asset
allocation program.

      A Fund's performance data will be based on historical results and will not
be intended to indicate future performance. A Fund's total return and yield will
vary based on market conditions, portfolio expenses, portfolio investments and
other factors. The value of a Fund's shares will fluctuate and an investor's
shares may be worth more or less than their original cost upon redemption. The
Trust may also, at its discretion, from time to time make a list of a Fund's
holdings available to investors upon request.

      Total return will be calculated separately for each class of shares in
existence. Because each class of shares is subject to different expenses, total
return with respect to each class of shares of a Fund will differ.

                               SHARES OF THE TRUST

      The Funds, except the CORE International Equity, CORE Small Cap Equity,
CORE Large Cap Value, CORE Large Cap Growth, Strategic Growth, Growth
Opportunities, European Equity, Japanese Equity, International Small Cap,
Emerging Markets Equity and Real Estate Securities Funds, were reorganized on
April 30, 1997 from series of a Maryland corporation to part of Goldman Sachs
Trust, a Delaware business trust, established by a Declaration of Trust dated
January 28, 1997.

      The Trustees have authority under the Trust's Declaration of Trust to
create and classify shares of beneficial interest in separate series, without
further action by shareholders. The Trustees also have authority to classify and
reclassify any series of shares into one or more classes of shares. As of the
date of this Additional Statement, the Trustees have classified the shares of
each of the Funds into five classes: Institutional Shares, Service Shares, Class
A Shares, Class B Shares and Class C Shares.

      Each Institutional Share, Service Share, Class A Share, Class B Share and
Class C Share of a Fund represents a proportionate interest in the assets
belonging to the applicable class of the Fund. All


                                      B-94
<PAGE>
 
expenses of a Fund are borne at the same rate by each class of shares, except
that fees under Service Plans are borne exclusively by Service Shares, fees
under Distribution and Service Plans are borne exclusively by Class A, Class B
or Class C Shares and transfer agency fees are borne at different rates by
different share classes. The Trustees may determine in the future that it is
appropriate to allocate other expenses differently between classes of shares and
may do so to the extent consistent with the rules of the SEC and positions of
the Internal Revenue Service. Each class of shares may have different minimum
investment requirements and be entitled to different shareholder services. With
limited exceptions, shares of a class may only be exchanged for shares of the
same or an equivalent class of another fund. See "Shareholder Guide" in the
Prospectus.

      Institutional Shares may be purchased at net asset value without a sales
charge for accounts in the name of an investor or institution that is not
compensated by a Fund under a Plan for services provided to the institution's
customers.

      Service Shares may be purchased at net asset value without a sales charge
for accounts held in the name of an institution that, directly or indirectly,
provides certain account administration and shareholder liaison services to its
customers, including maintenance of account records and processing orders to
purchase, redeem and exchange Service Shares. Service Shares bear the cost of
account administration fees at the annual rate of up to 0.50% of the average
daily net assets of the Fund attributable to Service Shares.

      Class A Shares are sold, with an initial sales charge of up to 5.5%,
through brokers and dealers who are members of the National Association of
Securities Dealers, Inc. and certain other financial service firms that have
sales agreements with Goldman Sachs. Class A Shares bear the cost of
distribution and service fees at the aggregate rate of up to 0.25% of the
average daily net assets of such Class A Shares (0.50% with respect to the CORE
International Equity, International Equity, European Equity, Japanese Equity,
International Small Cap, Emerging Markets, Asia Growth and Real Estate
Securities Funds). With respect to Class A Shares, the Distributor at its
discretion may use compensation for distribution services paid under the
Distribution and Services Plan for personal and account maintenance services and
expenses so long as such total compensation under the Plan does not exceed the
maximum cap on "service fees" imposed by the NASD.

      Class B Shares of the Funds are sold subject to a contingent deferred
sales charge of up to 5.0% through brokers and dealers who are members of the
National Association of Securities Dealers Inc. and certain other financial
services firms that have sales arrangements with Goldman Sachs. Class B Shares
bear the cost of distribution (Rule 12b-1) fees at the aggregate rate of up to
0.75% of the average daily net assets attributable to Class B Shares. Class B
Shares also bear the cost of service fees at an annual rate of up to 0.25% of
the average daily net assets attributable to Class B Shares.

      Class C Shares of the Funds are sold subject to a contingent deferred
sales charge of up to 1.0% through brokers and dealers who are members of the
National Association of Securities Dealers Inc. and certain other financial
services firms that have sales arrangements with Goldman Sachs. Class C Shares
bear the cost of distribution (Rule 12b-1) fees at the aggregate rate of up to
0.75% of the average daily net assets attributable to Class C Shares. Class C
Shares also bear the cost of service fees at an annual rate of up to 0.25% of
the average daily net assets attributable to Class C Shares.

      It is possible that an institution or its affiliate may offer different
classes of shares (i.e., Institutional, Service, Class A Shares, Class B Shares
and Class C Shares) to its customers and thus receive different compensation
with respect to different classes of shares of each Fund. Dividends paid by each
Fund, if any, with respect to each class of shares will be calculated in the
same manner, at the same time on the same day and will be the same amount,
except for differences caused by the differences in expenses discussed above.
Similarly, the net asset value per share may differ depending upon the class of
shares purchased.

      Certain aspects of the shares may be altered after advance notice to
shareholders if it is deemed necessary in order to satisfy certain tax
regulatory requirements.

      When issued, shares are fully paid and non-assessable. In the event of
liquidation, shareholders are entitled to share pro rata in the net assets of
the applicable class of the relevant Fund available for distribution to such
shareholders. All shares are freely transferable and have no preemptive,
subscription or conversion rights.

      The Act requires that where more than one class or series of shares
exists, each class or series must be preferred over all other classes or series
in respect of assets specifically allocated to such class or series. In
addition, Rule 18f-2 under the Act provides that any matter required to be
submitted by the provisions of the Act or applicable state law, or otherwise, to
the holders of the outstanding voting securities of an investment company such
as the Trust shall not be deemed to have been effectively acted upon unless
approved by the holders of a majority of the outstanding shares of each class or
series affected by such matter. Rule 18f-2 further provides that a class or
series shall be deemed to be affected by a matter unless the interests of each
class or series in the matter are substantially identical or the matter does not
affect any interest of such class or series. However, Rule 18f-2 exempts the
selection of independent public accountants, the approval of principal
distribution contracts and the election of trustees from the separate voting
requirements of Rule 18f-2.

      The Trust is not required to hold annual meetings of shareholders and does
not intend to hold such meetings. In the event that a meeting of shareholders is
held, each share of the Trust will be entitled, as determined by the Trustees,
either to one vote for each share or to one vote for each dollar of net asset
value represented by such shares on all matters presented to shareholders
including the elections of Trustees (this method of voting being referred to as
"dollar based voting"). However, to the extent required by the Act or otherwise
determined by the Trustees, series and classes of the Trust will vote separately
from each other. Shareholders of the Trust do not have cumulative voting rights
in the election of Trustees. Meetings of shareholders of the Trust, or any
series or class thereof, may be called by the Trustees, certain officers or upon
the written request of holders of 10% or more of the shares entitled to vote at
such meetings. The Trustees will call a special meeting of shareholders for the
purpose of electing Trustees, if, at any time, less than a majority of Trustees
holding office at the time were elected by shareholders. The shareholders of the
Trust will have voting rights only with respect to


                                      B-97
<PAGE>
 
the limited number of matters specified in the Declaration of Trust and such
other matters as the Trustees may determine or may be required by law.

      The Declaration of Trust provides for indemnification of Trustees,
officers, employees and agents of the Trust unless the recipient is adjudicated
(i) to be liable by reason of willful misfeasance, bad faith, gross negligence
or reckless disregard of the duties involved in the conduct of such person's
office or (ii) not to have acted in good faith in the reasonable belief that
such person's actions were in the best interest of the Trust. The Declaration of
Trust provides that, if any shareholder or former shareholder of any series is
held personally liable solely by reason of being or having been a shareholder
and not because of the shareholder's acts or omissions or for some other reason,
the shareholder or former shareholder (or heirs, executors, administrators,
legal representatives or general successors) shall be held harmless from and
indemnified against all loss and expense arising from such liability. The Trust,
acting on behalf of any affected series, must, upon request by such shareholder,
assume the defense of any claim made against such shareholder for any act or
obligation of the series and satisfy any judgment thereon from the assets of the
series.

      The Declaration of Trust permits the termination of the Trust or of any
series or class of the Trust (i) by a majority of the affected shareholders at a
meeting of shareholders of the Trust, series or class; or (ii) by a majority of
the Trustees without shareholder approval if the Trustees determine that such
action is in the best interest of the Trust, series or its respective
shareholders. The factors and events that the Trustees may take into account in
making such determination include (i) the inability of the Trust or any
successor series or class to maintain its assets at an appropriate size; (ii)
changes in laws or regulations governing the Trust, series or class or affecting
assets of the type in which it invests; or (iii) economic developments or trends
having a significant adverse impact on their business or operations.

      The Declaration of Trust authorizes the Trustees without shareholder
approval to cause the Trust, or any series thereof, to merge or consolidate with
any corporation, association, trust or their organization or sell or exchange
all or substantially all of the property belonging to the Trust or any series
thereof. In addition, the Trustees, without shareholder approval, may adopt a
master-feeder structure by investing all or a portion of the assets of a series
of the Trust in the securities of another open-end investment company.

      The Declaration of Trust permits the Trustees to amend the Declaration of
Trust without a shareholder vote. However, shareholders of the Trust have the
right to vote on any amendment (i) that would adversely affect the voting rights
of shareholder; (ii) that is required by law to be approved by shareholders;
(iii) that would amend the provisions of the Declaration of Trust regarding
amendments and supplements thereto; or (iv) that the Trustees determine to
submit to shareholders.

      The Trustees may appoint separate Trustees with respect to one or more
series or classes of the Trust's shares (the "Series Trustees"). Series Trustees
may, but are not required to, serve as Trustees of the Trust or any other series
or class of the Trust. The Series Trustees have, to the exclusion of any other
Trustees of the Delaware Trust, all the powers and authorities of Trustees under
the Declaration of Trust with respect to any other series or class.

Shareholder and Trustee Liability

      Under Delaware Law, the shareholders of the Funds are not generally
subject to liability for the debts or obligations of the Trust. Similarly,
Delaware law provides that a series of the Trust will not be liable for the
debts or obligations of any other series of the Trust. However, no similar
statutory or other authority limiting business trust shareholder liability
exists in other states. As a result, to the extent that a Delaware business
trust or a shareholder is subject to the jurisdiction of courts of such other
states, the courts may not apply Delaware law and may thereby subject the
Delaware business trust shareholders to liability. To guard against this risk,
the Declaration of Trust contains an express disclaimer of shareholder liability
for acts or obligations of a Fund. Notice of such disclaimer will normally be
given in each agreement, obligation or instrument entered into or executed by a
series or the Trustees. The Declaration of Trust provides for indemnification by
the relevant Fund for all loss suffered by a shareholder as a result of an
obligation of the series. The Declaration of Trust also provides that a series
shall, upon request, assume the defense of any claim made against any
shareholder for any act or obligation of the series and satisfy any judgment
thereon. In view of the above, the risk of personal liability of shareholders of
a Delaware business trust is remote.

      In addition to the requirements under Delaware law, the Declaration of
Trust provides that shareholders of a series may bring a derivative action on
behalf of the series only if the following conditions are met: (a) shareholders
eligible to bring such derivative action under Delaware law who hold at least
10% of the outstanding shares of the series, or 10% of the outstanding shares of
the class to which such action relates, shall join in the request for the
Trustees to commence such action; and (b) the Trustees must be afforded a
reasonable amount of time to consider such shareholder request and to
investigate the basis of and to employ other advisers in considering the merits
of the request and shall require an undertaking by the shareholders making such
request to reimburse the series for the expense of any such advisers in the
event that the Trustees determine not to bring such action.

      The Declaration of Trust further provides that the Trustees will not be
liable for error of judgment or mistakes of fact or law, but nothing in the
Declaration of Trust protects a Trustee against liability to which he or she
would otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties involved in the conduct of his
or her office.

                                    TAXATION

      The following is a summary of the principal U.S. federal income, and
certain state and local, tax considerations regarding the purchase, ownership
and disposition of shares in each Fund of the Trust. This summary does not
address special tax rules applicable to certain classes of investors, such as
tax-exempt entities, insurance companies and financial institutions. Each
prospective shareholder is urged to consult his own tax adviser with respect to
the specific federal, state, local and foreign tax consequences of investing in
each Fund. The summary is based on the laws in effect on the date of this
Additional Statement, which are subject to change.


                                      B-99

General

      Each Fund is a separate taxable entity. The Strategic Growth and Growth
Opportunities Funds each intend to elect and each other Fund has elected to be
treated and intends to qualify for each taxable year as a regulated investment
company under Subchapter M of the Code.

      Qualification as a regulated investment company under the Code requires,
among other things, that (a) a Fund derive at least 90% of its gross income for
its taxable year from dividends, interest, payments with respect to securities
loans and gains from the sale or other disposition of stocks or securities or
foreign currencies, or other income (including but not limited to gains from
options, futures, and forward contracts) derived with respect to its business of
investing in such stock, securities or currencies (the "90% gross income test");
and (b) such Fund diversify its holdings so that, at the close of each quarter
of its taxable year, (i) at least 50% of the market value of such Fund's total
(gross) assets is comprised of cash, cash items, U.S. Government securities,
securities of other regulated investment companies and other securities limited
in respect of any one issuer to an amount not greater in value than 5% of the
value of such Fund's total assets and to not more than 10% of the outstanding
voting securities of such issuer, and (ii) not more than 25% of the value of its
total (gross) assets is invested in the securities of any one issuer (other than
U.S. Government securities and securities of other regulated investment
companies) or two or more issuers controlled by the Fund and engaged in the
same, similar or related trades or businesses. For purposes of the 90% gross
income test, income that a Fund earns from equity interests in certain entities
that are not treated as corporations (e.g., partnerships or trusts) for U.S. tax
purposes will generally have the same character for such Fund as in the hands of
such an entity; consequently, a Fund may be required to limit its equity
investments in such entities that earn fee income, rental income, or other
nonqualifying income. In addition, future Treasury regulations could provide
that qualifying income under the 90% gross income test will not include gains
from foreign currency transactions that are not directly related to a Fund's
principal business of investing in stock or securities or options and futures
with respect to stock or securities. Using foreign currency positions or
entering into foreign currency options, futures and forward or swap contracts
for purposes other than hedging currency risk with respect to securities in a
Fund's portfolio or anticipated to be acquired may not qualify as
"directly-related" under these tests.

      If a Fund complies with such provisions, then in any taxable year in which
such Fund distributes, in compliance with the Code's timing and other
requirements, at least 90% of its "investment company taxable income" (which
includes dividends, taxable interest, taxable accrued original issue discount
and market discount income, income from securities lending, any net short-term
capital gain in excess of net long-term capital loss, certain net realized
foreign exchange gains and any other taxable income other than "net capital
gain," as defined below, and is reduced by deductible expenses), and at least
90% of the excess of its gross tax-exempt interest income (if any) over certain
disallowed deductions, such Fund (but not its shareholders) will be relieved of
federal income tax on any income of the Fund, including long-term capital gains,
distributed to shareholders. However, if a Fund retains any investment company
taxable income or "net capital gain" (the excess of net long-term capital gain
over net short-term capital loss), it will be subject to a tax at regular
corporate rates on the amount retained. If the Fund retains any net capital
gain, the Fund may designate the retained amount as undistributed capital gains
in a notice to its shareholders who, if subject to U.S. federal income tax on
long-term capital gains, (i) will be required to include in income for federal
income tax purposes, as long-term


                                     B-100
<PAGE>
 
capital gain, their shares of such undistributed amount, and (ii) will be
entitled to credit their proportionate shares of the tax paid by the Fund
against their U.S. federal income tax liabilities, if any, and to claim refunds
to the extent the credit exceeds such liabilities. For U.S. federal income tax
purposes, the tax basis of shares owned by a shareholder of the Fund will be
increased by an amount equal under current law to 65% of the amount of
undistributed net capital gain included in the shareholder's gross income. Each
Fund intends to distribute for each taxable year to its shareholders all or
substantially all of its investment company taxable income, net capital gain and
any net tax-exempt interest. Exchange control or other foreign laws, regulations
or practices may restrict repatriation of investment income, capital or the
proceeds of securities sales by foreign investors such as the CORE International
Equity, International Equity, European Equity, Japanese Equity, International
Small Cap, Emerging Markets Equity or Asia Growth Funds and may therefore make
it more difficult for such a Fund to satisfy the distribution requirements
described above, as well as the excise tax distribution requirements described
below. However, each Fund generally expects to be able to obtain sufficient cash
to satisfy such requirements from new investors, the sale of securities or other
sources. If for any taxable year a Fund does not qualify as a regulated
investment company, it will be taxed on all of its investment company taxable
income and net capital gain at corporate rates, and its distributions to
shareholders will be taxable as ordinary dividends to the extent of its current
and accumulated earnings and profits.

      In order to avoid a 4% federal excise tax, each Fund must distribute (or
be deemed to have distributed) by December 31 of each calendar year at least 98%
of its taxable ordinary income for such year, at least 98% of the excess of its
capital gains over its capital losses (generally computed on the basis of the
one-year period ending on October 31 of such year), and all taxable ordinary
income and the excess of capital gains over capital losses for the previous year
that were not distributed for such year and on which the Fund paid no federal
income tax. For federal income tax purposes, dividends declared by a Fund in
October, November or December to shareholders of record on a specified date in
such a month and paid during January of the following year are taxable to such
shareholders as if received on December 31 of the year declared. The Funds
anticipate that they will generally make timely distributions of income and
capital gains in compliance with these requirements so that they will generally
not be required to pay the excise tax. For federal income tax purposes, each
Fund is permitted to carry forward a net capital loss in any year to offset its
own capital gains, if any, during the eight years following the year of the
loss. At January 31, 1999 the following Funds had capital loss carry forwards
approximating the amount indicated for federal tax purposes, expiring in the
year indicated: Balanced Fund, $2,357,000 (expires 2006); Growth and Income
Fund, $45,955,000 (expires 2006); CORE Large Cap Growth Fund, $18,495,000
(expires 2006); CORE Small Cap Equity, $19,364,000 (expires 2006); CORE
International Equity Fund, $14,803,548 (expires 2006); Mid Cap Value Fund,
$25,324,000 (expires 2006); Small Cap Value Fund, $9,630,000 (expires 2007);
Japanese Equity Fund, $103,000 (expires 2006); International Small Cap Fund,
$15,000 (expires 2006); Emerging Markets Equity, $33,647,000 (expires 2006); and
Asia Growth, $93,204,000 (expires 2006). At December 31, 1998, the Real Estate
Securities Fund had capital loss carry forwards approximating $254,182, expiring
in 2006. These amounts are available to be carried forward to offset future
capital gains to the extent permitted by the Code and applicable tax
regulations.

      Gains and losses on the sale, lapse, or other termination of options and
futures contracts, options thereon and certain forward contracts (except certain
foreign currency options, forward contracts and


                                     B-101
<PAGE>
 
futures contracts) will generally be treated as capital gains and losses.
Certain of the futures contracts, forward contracts and options held by a Fund
will be required to be "marked-to-market" for federal income tax purposes, that
is, treated as having been sold at their fair market value on the last day of
the Fund's taxable year. These provisions may require a Fund to recognize income
or gains without a concurrent receipt of cash. Any gain or loss recognized on
actual or deemed sales of these futures contracts, forward contracts, or options
will (except for certain foreign currency options, forward contracts, and
futures contracts) be treated as 60% long-term capital gain or loss and 40%
short-term capital gain or loss. As a result of certain hedging transactions
entered into by a Fund, the Fund may be required to defer the recognition of
losses on futures contracts, forward contracts, and options or underlying
securities or foreign currencies to the extent of any unrecognized gains on
related positions held by such Fund and the characterization of gains or losses
as long-term or short-term may be changed. The tax provisions described above
applicable to options, futures and forward contracts may affect the amount,
timing and character of a Fund's distributions to shareholders. Application of
certain requirements for qualification as a regulated investment company and/or
these tax rules to certain investment practices, such as dollar rolls, or
certain derivatives such as interest rate swaps, floors, caps and collars and
currency, mortgage or index swaps may be unclear in some respects, and a Fund
may therefore be required to limit its participation in such transactions.
Certain tax elections may be available to a Fund to mitigate some of the
unfavorable consequences described in this paragraph.

      Section 988 of the Code contains special tax rules applicable to certain
foreign currency transactions and instruments that may affect the amount, timing
and character of income, gain or loss recognized by a Fund. Under these rules,
foreign exchange gain or loss realized with respect to foreign currencies and
certain futures and options thereon, foreign currency-denominated debt
instruments, foreign currency forward contracts, and foreign
currency-denominated payables and receivables will generally be treated as
ordinary income or loss, although in some cases elections may be available that
would alter this treatment. If a net foreign exchange loss treated as ordinary
loss under Section 988 of the Code were to exceed a Fund's investment company
taxable income (computed without regard to such loss) for a taxable year, the
resulting loss would not be deductible by the Fund or its shareholders in future
years. Net loss, if any, from certain foregoing currency transactions or
instruments could exceed net investment income otherwise calculated for
accounting purposes with the result being either no dividends being paid or a
portion of a Fund's dividends being treated as a return of capital for tax
purposes, nontaxable to the extent of a shareholder's tax basis in his shares
and, once such basis is exhausted, generally giving rise to capital gains.

      A Fund's investment in zero coupon securities, deferred interest
securities, certain structured securities or other securities bearing original
issue discount or, if a Fund elects to include market discount in income
currently, market discount, as well as any "mark to market" gain from certain
options, futures or forward contracts, as described above, will generally cause
it to realize income or gain prior to the receipt of cash payments with respect
to these securities or contracts. In order to obtain cash to enable it to
distribute this income or gain, maintain its qualification as a regulated
investment company and avoid federal income or excise taxes, the Fund may be
required to liquidate portfolio securities that it might otherwise have
continued to hold.

      Each Fund (other than CORE Large Cap Value, CORE U.S. Equity, CORE Large
Cap Growth and CORE Small Cap Equity Funds) anticipates that it will be subject
to foreign taxes on its income


                                     B-102
<PAGE>
 
(possibly including, in some cases, capital gains) from foreign securities. Tax
conventions between certain countries and the U.S. may reduce or eliminate such
taxes in some cases. If, as may occur for CORE International Equity,
International Equity, European Equity, Japanese Equity, International Small Cap,
Emerging Markets Equity and Asia Growth Funds, more than 50% of a Fund's total
assets at the close of any taxable year consists of stock or securities of
foreign corporations, the Fund may file an election with the Internal Revenue
Service pursuant to which shareholders of the Fund would be required to (i)
include in ordinary gross income (in addition to taxable dividends actually
received) their pro rata shares of foreign income taxes paid by the Fund that
are treated as income taxes under U.S. tax regulations (which excludes, for
example, stamp taxes, securities transaction taxes, and similar taxes) even
though not actually received by such shareholders, and (ii) treat such
respective pro rata portions as foreign income taxes paid by them.

      If the CORE International Equity, International Equity, European Equity,
Japanese Equity, International Small Cap, Emerging Markets Equity and Asia
Growth Funds make this election, its respective shareholders may then deduct
such pro rata portions of qualified foreign taxes in computing their taxable
incomes, or, alternatively, use them as foreign tax credits, subject to
applicable limitations, against their U.S. federal income taxes. Shareholders
who do not itemize deductions for federal income tax purposes will not, however,
be able to deduct their pro rata portion of foreign taxes paid by a Fund,
although such shareholders will be required to include their shares of such
taxes in gross income if the election is made.

      If a shareholder chooses to take credit for the foreign taxes deemed paid
by such shareholder as a result of any such election by CORE International
Equity, International Equity, European Equity, Japanese Equity, International
Small Cap, Emerging Markets Equity or Asia Growth Funds, the amount of the
credit that may be claimed in any year may not exceed the same proportion of the
U.S. tax against which such credit is taken which the shareholder's taxable
income from foreign sources (but not in excess of the shareholder's entire
taxable income) bears to his entire taxable income. For this purpose,
distributions from long-term and short-term capital gains or foreign currency
gains by a Fund will generally not be treated as income from foreign sources.
This foreign tax credit limitation may also be applied separately to certain
specific categories of foreign-source income and the related foreign taxes. As a
result of these rules, which have different effects depending upon each
shareholder's particular tax situation, certain shareholders of CORE
International Equity, International Equity, European Equity, Japanese Equity,
International Small Cap, Emerging Markets Equity and Asia Growth Funds may not
be able to claim a credit for the full amount of their proportionate share of
the foreign taxes paid by such Fund even if the election is made by such a Fund.

      Shareholders who are not liable for U.S. federal income taxes, including
tax-exempt shareholders, will ordinarily not benefit from this election. Each
year, if any, that the CORE International Equity, International Equity, European
Equity, Japanese Equity, International Small Cap, Emerging Markets Equity or
Asia Growth Fund files the election described above, its shareholders will be
notified of the amount of (i) each shareholder's pro rata share of qualified
foreign taxes paid by a Fund and (ii) the portion of Fund dividends which
represents income from each foreign country. The other Funds will not be
entitled to elect to pass foreign taxes and associated credits or deductions
through to their shareholders because they will not satisfy the 50% requirement
described above. If a


                                     B-103
<PAGE>
 
Fund cannot or does not make this election, it may deduct such taxes in
computing the amount it is required to distribute.

      If a Fund acquires stock (including, under proposed regulations, an option
to acquire stock such as is inherent in a convertible bond) in certain foreign
corporations that receive at least 75% of their annual gross income from passive
sources (such as interest, dividends, rents, royalties or capital gain) or hold
at least 50% of their assets in investments producing such passive income
("passive foreign investment companies"), the Fund could be subject to federal
income tax and additional interest charges on "excess distributions" received
from such companies or gain from the sale of stock in such companies, even if
all income or gain actually received by the Fund is timely distributed to its
shareholders. The Fund would not be able to pass through to its shareholders any
credit or deduction for such a tax. In some cases, elections may be available
that would ameliorate these adverse tax consequences, but such elections would
require the Fund to include each year certain amounts as income or gain (subject
to the distribution requirements described above) without a concurrent receipt
of cash. Each Fund may limit and/or manage its holdings in passive foreign
investment companies to minimize its tax liability or maximize its return from
these investments.

      Investments in lower-rated securities may present special tax issues for a
Fund to the extent actual or anticipated defaults may be more likely with
respect to such securities. Tax rules are not entirely clear about issues such
as when a Fund may cease to accrue interest, original issue discount, or market
discount; when and to what extent deductions may be taken for bad debts or
worthless securities; how payments received on obligations in default should be
allocated between principal and income; and whether exchanges of debt
obligations in a workout context are taxable. These and other issues will be
addressed by a Fund, in the event it invests in such securities, in order to
seek to eliminate or minimize any adverse tax consequences.

Taxable U.S. Shareholders - Distributions

      For U.S. federal income tax purposes, distributions by a Fund, whether
reinvested in additional shares or paid in cash, generally will be taxable to
shareholders who are subject to tax. Shareholders receiving a distribution in
the form of newly issued shares will be treated for U.S. federal income tax
purposes as receiving a distribution in an amount equal to the amount of cash
they would have received had they elected to receive cash and will have a cost
basis in each share received equal to such amount divided by the number of
shares received.

      Distributions from investment company taxable income for the year will be
taxable as ordinary income. Distributions designated as derived from a Fund's
dividend income, if any, that would be eligible for the dividends received
deduction if such Fund were not a regulated investment company may be eligible,
for the dividends received deduction for corporate shareholders. The
dividends-received deduction, if available, is reduced to the extent the shares
with respect to which the dividends are received are treated as debt-financed
under federal income tax law and is eliminated if the shares are deemed to have
been held for less than a minimum period, generally 46 days. Because eligible
dividends are limited to those a Fund receives from U.S. domestic corporations,
it is unlikely that a substantial portion of the distributions made by CORE
International Equity, International Equity, European Equity, Japanese Equity,
International Small Cap, Asia Growth and Emerging Markets


                                     B-104
<PAGE>
 
Equity Funds will qualify for the dividends-received deduction. The entire
dividend, including the deducted amount, is considered in determining the
excess, if any, of a corporate shareholder's adjusted current earnings over its
alternative minimum taxable income, which may increase its liability for the
federal alternative minimum tax, and the dividend may, if it is treated as an
"extraordinary dividend" under the Code, reduce such shareholder's tax basis in
its shares of a Fund. Capital gain dividends (i.e., dividends from net capital
gain) if designated as such in a written notice to shareholders mailed not later
than 60 days after a Fund's taxable year closes, will be taxed to shareholders
as long-term capital gain regardless of how long shares have been held by
shareholders, but are not eligible for the dividends received deduction for
corporations. Such long-term capital gain will be taxed at a maximum rate of
20%. Distributions, if any, that are in excess of a Fund's current and
accumulated earnings and profits will first reduce a shareholder's tax basis in
his shares and, after such basis is reduced to zero, will generally constitute
capital gains to a shareholder who holds his shares as capital assets.

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

Taxable U.S. Shareholders - Sale of Shares

      When a shareholder's shares are sold, redeemed or otherwise disposed of in
a transaction that is treated as a sale for tax purposes, the shareholder will
generally recognize gain or loss equal to the difference between the
shareholder's adjusted tax basis in the shares and the cash, or fair market
value of any property, received. If the shareholder holds the shares as a
capital asset at the time of sale, the character of the gain or loss should be
capital, and treated as long-term if the shareholder's holding period is more
than one year, and short-term otherwise. In general, the maximum long-term
capital gain rate will be 20% for capital gains on assets held more than one
year. Shareholders should consult their own tax advisers with reference to their
particular circumstances to determine whether a redemption (including an
exchange) or other disposition of Fund shares is properly treated as a sale for
tax purposes, as is assumed in this discussion. If a shareholder receives a
capital gain dividend with respect to shares and such shares have a tax holding
period of six months or less at the time of a sale or redemption of such shares,
then any loss the shareholder realizes on the sale or redemption will be treated
as a long-term capital loss to the extent of such capital gain dividend. All or
a portion of any sales load paid upon the purchase of shares of a Fund will not
be taken into account in determining gain or loss on the redemption or exchange
of such shares within 90 days after their purchase to the extent the redemption
proceeds are reinvested, or the exchange is effected, without payment of an
additional sales load pursuant to the reinvestment or exchange privilege. The
load not taken into account will be added to the tax basis of the newly-acquired
shares. Additionally, any loss realized on a sale or redemption of shares of a
Fund may be disallowed under "wash sale" rules to the extent the shares disposed
of are replaced with other shares of the same Fund within a period of 61 days
beginning 30 days before and ending 30 days after the shares are disposed of,
such as pursuant to a dividend reinvestment in shares of such Fund. If
disallowed, the loss will be reflected in an adjustment to the basis of the
shares acquired.


                                     B-105
<PAGE>
 
      Each Fund may be required to withhold, as "backup withholding," federal
income tax at a rate of 31% from dividends (including capital gain dividends)
and share redemption and exchange proceeds to individuals and other non-exempt
shareholders who fail to furnish such Fund with a correct taxpayer
identification number ("TIN") certified under penalties of perjury, or if the
Internal Revenue Service or a broker notifies the Fund that the payee is subject
to backup withholding as a result of failing to properly report interest or
dividend income to the Internal Revenue Service or that the TIN furnished by the
payee to the Fund is incorrect, or if (when required to do so) the payee fails
to certify under penalties of perjury that it is not subject to backup
withholding. A Fund may refuse to accept an application that does not contain
any required TIN or certification that the TIN provided is correct. If the
backup withholding provisions are applicable, any such dividends and proceeds,
whether paid in cash or reinvested in additional shares, will be reduced by the
amounts required to be withheld. Any amounts withheld may be credited against a
shareholder's U.S. federal income tax liability. If you do not have a TIN, you
should apply for one immediately by contacting your local office of the Social
Security Administration or the Internal Revenue Service (IRS). Backup
withholding could apply to payments relating to your account while you are
waiting receipt of a TIN. Special rules apply for certain entities. For example,
for an account established under a Uniform Gifts or Transfer to Minors Act, the
TIN of the minor should be furnished.

Non-U.S. Shareholders

      The discussion above relates solely to U.S. federal income tax law as it
applies to "U.S. persons" subject to tax under such law. Shareholders who, as to
the United States, are not "U.S. persons," (i.e., are nonresident aliens,
foreign corporations, fiduciaries of foreign trusts or estates, foreign
partnerships or other non-U.S. investors) generally will be subject to U.S.
federal withholding tax at the rate of 30% on distributions treated as ordinary
income unless the tax is reduced or eliminated pursuant to a tax treaty or the
dividends are effectively connected with a U.S. trade or business of the
shareholder. In the latter case the dividends will be subject to tax on a net
income basis at the graduated rates applicable to U.S. individuals or domestic
corporations. Distributions of net capital gain, including amounts retained by a
Fund which are designated as undistributed capital gains, to a non-U.S.
shareholder will not be subject to U.S. federal income or withholding tax unless
the distributions are effectively connected with the shareholder's trade or
business in the United States or, in the case of a shareholder who is a
nonresident alien individual, the shareholder is present in the United States
for 183 days or more during the taxable year and certain other conditions are
met. Non-U.S. shareholders may also be subject to U.S. federal withholding tax
on deemed income resulting from any election by CORE International Equity,
International Equity, European Equity, Japanese Equity, International Small Cap,
Emerging Markets Equity or Asia Growth Funds to treat qualified foreign taxes it
pays as passed through to shareholders (as described above), but they may not be
able to claim a U.S. tax credit or deduction with respect to such taxes.

      Any capital gain realized by a non-U.S. shareholder upon a sale or
redemption of shares of a Fund will not be subject to U.S. federal income or
withholding tax unless the gain is effectively connected with the shareholder's
trade or business in the U.S., or in the case of a shareholder who is a
nonresident alien individual, the shareholder is present in the U.S. for 183
days or more during the taxable year and certain other conditions are met.


                                     B-106
<PAGE>
 
      Non-U.S. persons who fail to furnish a Fund with an IRS Form W-8 or an
acceptable substitute may be subject to backup withholding at the rate of 31% on
capital gain dividends and the proceeds of redemptions and exchanges. Each
shareholder who is not a U.S. person should consult his or her tax adviser
regarding the U.S. and non-U.S. tax consequences of ownership of shares of and
receipt of distributions from the Funds.

State and Local

      Each Fund may be subject to state or local taxes in jurisdictions in which
such Fund may be deemed to be doing business. In addition, in those states or
localities which have income tax laws, the treatment of such Fund and its
shareholders under such laws may differ from their treatment under federal
income tax laws, and investment in such Fund may have tax consequences for
shareholders different from those of a direct investment in such Fund's
portfolio securities. Shareholders should consult their own tax advisers
concerning these matters.

                              FINANCIAL STATEMENTS

      The audited financial statements and related reports of Arthur Andersen
LLP, independent public accountants, contained in each Fund's 1999 Annual Report
are hereby incorporated by reference. A copy of the annual reports may be
obtained without charge by writing Goldman, Sachs & Co., 4900 Sears Tower,
Chicago, Illinois 60606 or by calling Goldman, Sachs & Co., at the telephone
number on the back cover of each Fund's prospectus. No other part of the Annual
Reports are incorporated herein by reference.

                                OTHER INFORMATION

      Each Fund will redeem shares solely in cash up to the lesser of $250,000
or 1% of the net asset value of the Fund during any 90-day period for any one
shareholder. Each Fund, however, reserves the right to pay redemptions exceeding
$250,000 or 1% of the net asset value of the Fund at the time of redemption by a
distribution in kind of securities (instead of cash) from such Fund. The
securities distributed in kind would be readily marketable and would be valued
for this purpose using the same method employed in calculating the Fund's net
asset value per share. See "Net Asset Value." If a shareholder receives
redemption proceeds in kind, the shareholder should expect to incur transaction
costs upon the disposition of the securities received in the redemption.

      The right of a shareholder to redeem shares and the date of payment by
each Fund may be suspended for more than seven days for any period during which
the New York Stock Exchange is closed, other than the customary weekends or
holidays, or when trading on such Exchange is restricted as determined by the
SEC; or during any emergency, as determined by the SEC, as a result of which it
is not reasonably practicable for such Fund to dispose of securities owned by it
or fairly 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 of such Fund.

      As stated in the Prospectuses, the Trust may authorize Service
Organizations and other institutions that provide recordkeeping, reporting and
processing services to their customers to accept on


                                     B-107
<PAGE>
 
the Trust's behalf purchase, redemption and exchange orders placed by or on
behalf of their customers and, if approved by the Trust, to designate other
intermediaries to accept such orders. These institutions may receive payments
from the Trust or Goldman Sachs for their services. Certain Service
Organizations or institutions may enter into sub-transfer agency agreements with
the Trust or Goldman Sachs with respect to their services.

      The Investment Adviser, Distributor and/or their affiliates may pay, out
of their own assets, compensation to Authorized Dealers, Service Organization
and other financial intermediaries ("Intermediaries") for the sale and
distribution of Shares of the Funds and/or for the servicing of those shares.
These payments ("Additional Payments") would be in addition to the payments by
the Funds described in the Funds' Prospectus and this Additional Statement for
distribution and shareholder servicing and processing, and would also be in
addition to the sales commissions payable to Intermediaries as set forth in the
Prospectus. These Additional Payments may take the form of "due diligence"
payments for an Intermediary's examination of the Funds and payments for
providing extra employee training and information relating to the Funds;
"listing" fees for the placement of the Funds on an Intermediary's list of
mutual funds available for purchase by its customers; "finders" or "referral"
fees for directing investors to the Funds; "marketing support" fees for
providing assistance in promoting the sale of the Funds' shares; and payments
for the sale of shares and/or the maintenance of share balances. In addition,
the Investment Adviser, Distributor and/or their affiliates may make Additional
Payments for subaccounting, administrative and/or shareholder processing
services that are in addition to the shareholder servicing and processing fees
paid by the Funds. The Additional Payments made by the Investment Adviser,
Distributor and their affiliates may be a fixed dollar amount, may be based on
the number of customer accounts maintained by an Intermediary, or may be based
on a percentage of the value of shares sold to, or held by, customers of the
Intermediary involved, and may be different for different Intermediaries.
Furthermore, the Investment Adviser, Distributor and/or their affiliates may, to
the extent permitted by applicable regulations, contribute to various non-cash
and cash incentive arrangements to promote the sale of shares, as well as
sponsor various educational programs, sales contests and/or promotions. The
Investment Adviser, Distributor and their affiliates may also pay for the travel
expenses, meals, lodging and entertainment of Intermediaries and their
salespersons and guests in connection with educational, sales and promotional
programs subject to applicable NASD regulations.

      In the interest of economy and convenience, the Trust does not issue
certificates representing the Funds' shares. Instead, the Transfer Agent
maintains a record of each shareholder's ownership. Each shareholder receives
confirmation of purchase and redemption orders from the Transfer Agent. Fund
shares and any dividends and distributions paid by the Funds are reflected in
account statements from the Transfer Agent.

      The Prospectuses and this Additional Statement do not contain all the
information included in the Registration Statement filed with the SEC under the
1933 Act with respect to the securities offered by the Prospectuses. Certain
portions of the Registration Statement have been omitted from the Prospectuses
and this Additional Statement pursuant to the rules and regulations of the SEC.
The Registration Statement including the exhibits filed therewith may be

                         DISTRIBUTION AND SERVICE PLANS
            (Class A Shares, Class B Shares and Class C Shares Only)

      Distribution and Service Plans. As described in the Prospectus, the Trust
has adopted, on behalf of Class A, Class B and Class C Shares of each Fund,
distribution and service plans (each a "Plan") pursuant to Rule 12b-1 under the
Act. See "Shareholder Services" in the Prospectus.

      The Plans for each Fund were most recently approved on April 27, 1999 by a
majority vote of the Trustees of the Trust, including a majority of the
non-interested Trustees of the Trust who have no direct or indirect financial
interest in the Plans, cast in person at a meeting called for the purpose of
approving the Plans.

      The compensation for distribution services payable under a Plan may not
exceed 0.25%, 0.75% and 0.75%, per annum of a Fund's average daily net assets
attributable to Class A, Class B and Class C Shares respectively, of such Fund.
Under the Plans for Class A (CORE International Equity, International Equity,
European Equity, Japanese Equity, International Small Cap, Emerging Markets
Equity, Asia Growth and Real Estate Securities Funds only), Class B and Class C
Shares, Goldman Sachs is also entitled to received a separate fee for personal
and account maintenance services equal to an annual basis of 0.25% of each
Fund's average daily net assets attributable to Class A, Class B or Class C
Shares. With respect to Class A Shares, the Distributor at its discretion may
use compensation for distribution services paid under the Plan for personal and
account maintenance services and expenses so long as such total compensation
under the Plan does not exceed the maximum cap on "service fees" imposed by the
NASD.

      Each Plan is a compensation plan which provides for the payment of a
specified fee without regard to the expenses actually incurred by Goldman Sachs.
If such fee exceeds Goldman Sachs' expenses, Goldman Sachs may realize a profit
from these arrangements. The distribution fees received by Goldman Sachs under
the Plans and contingent deferred sales charge on Class A, Class B and Class C
Shares may be sold by Goldman Sachs as distributor to entities which provide
financing for payments to Authorized Dealers in respect of sales of Class A,
Class B and Class C Shares. To the extent such fees are not paid to such
dealers, Goldman Sachs may retain such fee as compensation for its services and
expenses of distributing the Funds' Class A, Class B and Class C Shares.

      Under each Plan, Goldman Sachs, as distributor of each Fund's Class A,
Class B and Class C Shares, will provide to the Trustees of the Trust for their
review, and the Trustees of the Trust will review at least quarterly, a written
report of the services provided and amounts expended by Goldman Sachs under the
Plans and the purposes for which such services were performed and expenditures
were made.


                                     B-109
<PAGE>
 
      The Plans will remain in effect until May 1, 2000 and from year to year
thereafter, provided that such continuance is approved annually by a majority
vote of the Trustees of the Trust, including a majority of the non-interested
Trustees of the Trust who have no direct or indirect financial interest in the
Plans. The Plans may not be amended to increase materially the amount of
distribution compensation without approval of a majority of the outstanding
Class A, Class B or Class C Shares of the affected Fund and share class. All
material amendments of a Plan must also be approved by the Trustees of the Trust
in the manner described above. A Plan may be terminated at any time as to any
Fund without payment of any penalty by a vote of a majority of the
non-interested Trustees of the Trust or by vote of a majority of the Class A,
Class B or Class C Shares, respectively, of the applicable Fund and share class.
If a Plan was terminated by the Trustees of the Trust and no successor plan was
adopted, the Fund would cease to make payments to Goldman Sachs under the Plan
and Goldman Sachs would be unable to recover the amount of any of its
unreimbursed expenditures. So long as a Plan is in effect, the selection and
nomination of non-interested Trustees of the Trust will be committed to the
discretion of the non-interested Trustees of the Trust. The Trustees of the
Trust have determined that in their judgment there is a reasonable likelihood
that the Plans will benefit the Funds and their Class A, Class B and Class C
Shareholders.

with distribution under the Class A Plan, Class B Plan and Class C Plan with
respect to the Real Estate Securities Fund: $293, $0 and $1, respectively
(compensation to dealers); $160,926, $3,872 and $383, respectively (compensation

$466, respectively (allocable overhead, telephone and travel expenses); $14,958,
$377 and $37, respectively (printing and mailing of prospectuses to other than
current shareholders); and $52,610, $1,326 and $131, respectively (preparation
and distribution of sales literature and advertising). With respect to
compensation to dealers, advance commissions paid to dealers of 1%, 4% and 1% on
Class A Shares, Class B Shares and Class C Shares, respectively, are considered
deferred assets which are amortized over a period of 1 year, 6 years and 1 year,
respectively; amounts presented above reflect amortization expense record during

of the compensation received by Goldman Sachs under the Plans. The payments
under the plans were used by Goldman Sachs to compensate it for the expenses
shown above on a pro-rata basis.

      For the fiscal years and periods indicated below, Goldman Sachs received
service fees from the Funds pursuant to the Plans then in existence at the rate
of 0.25% of each Fund's average daily net assets attributable to Class A, Class
B, or Class C Shares, which totaled:

Other Purchase Information

If shares of a Fund are held in a "street name" account with an Authorized
Dealer, all recordkeeping, transaction processing and payments of distributions
relating to the beneficial owner's account will be performed by the Authorized
Dealer, and not by the Fund and its Transfer Agent. Since the Funds will have no
record of the beneficial owner's transactions, a beneficial owner should contact
the Authorized Dealer to purchase, redeem or exchange shares, to make changes in
or give instructions concerning the account or to obtain information about the
account. The transfer of shares in a "street name" account to an account with
another dealer or to an account directly with the Fund involves special
procedures and will require the beneficial owner to obtain historical purchase
information about the shares in the account from the Authorized Dealer.

Right of Accumulation (Class A)

A Class A shareholder qualifies for cumulative quantity discounts if the current
purchase price of the new investment plus the shareholder's current holdings of
existing Class A Shares (acquired by purchase or exchange) of the Funds and
Class A Shares of any other Goldman Sachs Fund (as defined in the Prospectus)
total the requisite amount for receiving a discount. For example, if a
shareholder owns shares with a current market value of $35,000 and purchases
additional Class A Shares of any Fund with a purchase price of $25,000, the
sales charge for the $25,000 purchase would be 4.75% (the rate applicable to a
single purchase of more than $50,000). Class A Shares purchased without the
imposition of a sales charge may not be aggregated with Class A Shares purchased
subject to a sales charge. Class A Shares of the Funds and any other Goldman
Sachs Fund purchased (i) by an individual, his spouse and his children, and (ii)
by a trustee, guardian or other fiduciary of a single trust estate or a single
fiduciary account, will be combined for the purpose of determining whether a
purchase will qualify for such right of accumulation and, if qualifying, the
applicable sales charge level. For purposes of applying the right of
accumulation, shares of the Funds and any other Goldman Sachs Fund purchased by
an existing client of the Private Client Services Division of Goldman Sachs will
be combined with Class A Shares held by any other Private Client Services
account. In addition, Class A Shares of the Funds and Class A Shares of any
other Goldman Sachs Fund purchased by partners, directors, officers or employees
of the same business organization, groups of individuals represented by and
investing on the recommendation of the same accounting firm, certain affinity
groups or other similar organizations (collectively, "eligible persons") may be
combined for the purpose of determining whether a purchase will qualify for the
right of accumulation and, if qualifying, the applicable sales charge level.
This right of accumulation is subject to the following conditions: (i) the
business organization's, group's or firm's agreement to cooperate in the
offering of the Funds' shares to eligible persons; and (ii) notification to the
Funds at the time of purchase that the investor is eligible for this right of
accumulation. In addition, in connection with SIMPLE IRA accounts, cumulative
quantity discounts are available on a per plan basis if (1) your employee has
been assigned a cumulative discount number by Goldman Sachs, and (2) your
account, alone or in combination with the accounts of other plan participants
also invested in Class A Shares of the Goldman Sachs Funds, totals the requisite
aggregate amount as described in the Prospectus.

Statement of Intention (Class A)

If a shareholder anticipates purchasing at least $50,000 of Class A Shares of a
Fund alone or in combination with Class A Shares of any other Goldman Sachs Fund
within a 13-month period, the shareholder may purchase shares of the Fund at a
reduced sales charge by submitting a Statement of Intention (the "Statement").
Shares purchased pursuant to a Statement will be eligible for the same sales
charge discount that would have been available if all of the purchases had been
made at the same time. The shareholder or his Authorized Dealer must inform
Goldman Sachs that the Statement is in effect each time shares are purchased.
There is no obligation to purchase the full amount of shares indicated in the
Statement. A shareholder may include the value of all Class A Shares on which a
sales charge has previously been paid as an "accumulation credit" toward the
completion of the Statement, but a price readjustment will be made only on Class
A Shares purchased within ninety (90) days before submitting the Statement. The
Statement authorizes the Transfer Agent to hold in escrow a sufficient number of
shares which can be redeemed to make up any difference in the sales charge on
the amount actually invested. For purposes of satisfying the amount specified on
the Statement, the gross amount of each investment, exclusive of any
appreciation on shares previously purchased, will be taken into account.

The provisions applicable to the Statement, and the terms of the related escrow
agreement, are set forth in Appendix C to this Additional Statement.

Cross-Reinvestment of Dividends and Distributions

Shareholders may receive dividends and distributions in additional Shares of the
same class of the Fund in which they have invested or they may elect to receive
them in cash or Shares of the same class of other mutual funds sponsored by
Goldman Sachs (the "Goldman Sachs Funds") or ILA Service Units of the Prime
Obligations Portfolio or the Tax-Exempt Diversified Portfolio, if they hold
Class A Shares of a Fund, or ILA, Class B or Class C Units of the Prime
Obligations Portfolio, if they hold Class B or Class C Shares of a Fund (the
"ILA Portfolios").

A Fund shareholder should obtain and read the prospectus relating to any other
Fund, Goldman Sachs Fund or ILA Portfolio and its shares or units and consider
its investment objective, policies and applicable fees before electing
cross-reinvestment into that Fund or Portfolio. The election to cross-reinvest
dividends and capital gain distributions will not affect the tax treatment of
such dividends and distributions, which will be treated as received by the
shareholder and then used to purchase shares of the acquired fund. Such
reinvestment of dividends and distributions in shares of other Goldman Sachs
Funds or in units of ILA Portfolios is available only in states where such
reinvestment may legally be made.

Automatic Exchange Program

A Fund shareholder may elect to exchange automatically a specified dollar amount
of shares of a Fund into an identical account of another Fund or an account
registered in a different name or with a different address, social security or
other taxpayer identification number, provided that the account in the acquired
fund has been established, appropriate signatures have been obtained and the


                                     B-122
<PAGE>
 
minimum initial investment requirement has been satisfied. A Fund shareholder
should obtain and read the prospectus relating to any other Goldman Sachs Fund
and its shares and consider its investment objective, policies and applicable
fees and expenses before electing an automatic exchange into that Goldman Sachs
Fund.

Systematic Withdrawal Plan

A systematic withdrawal plan (the "Systematic Withdrawal Plan") is available to
shareholders of a Fund whose shares are worth at least $5,000. The Systematic
Withdrawal Plan provides for monthly payments to the participating shareholder
of any amount not less than $50.

Dividends and capital gain distributions on shares held under the Systematic
Withdrawal Plan are reinvested in additional full and fractional shares of the
applicable Fund at net asset value. The Transfer Agent acts as agent for the
shareholder in redeeming sufficient full and fractional shares to provide the
amount of the systematic withdrawal payment. The Systematic Withdrawal Plan may
be terminated at any time. Goldman Sachs reserves the right to initiate a fee of
up to $5 per withdrawal, upon thirty (30) days written notice to the
shareholder. Withdrawal payments should not be considered to be dividends, yield
or income. If periodic withdrawals continuously exceed new purchases and
reinvested dividends and capital gains distributions, the shareholder's original
investment will be correspondingly reduced and ultimately exhausted. The
maintenance of a withdrawal plan concurrently with purchases of additional Class
A, Class B or Class C Shares would be disadvantageous because of the sales
charge imposed on purchases of Class A Shares or the imposition of a CDSC on
redemptions of Class A, Class B or Class C Shares. The CDSC applicable to Class
A, Class B or Class C Shares redeemed under a systematic withdrawal plan may be
waived. See "Shareholder Guide" in the Prospectus. In addition, each withdrawal
constitutes a redemption of shares, and any gain or loss realized must be
reported for federal and state income tax purposes. A shareholder should consult
his or her own tax adviser with regard to the tax consequences of participating
in the Systematic Withdrawal Plan. For further information or to request a
Systematic Withdrawal Plan, please write or call the Transfer Agent.

                                  SERVICE PLAN
                              (Service Shares Only)

The Funds have adopted a service plan (the "Plan") with respect to its Service
Shares which authorizes it to compensate Service Organizations for providing
certain administration services and personal and account maintenance services to
their customers who are or may become beneficial owners of such Shares. Pursuant
to the Plan, each Fund enters into agreements with Service Organizations which
purchase Service Shares of the Fund on behalf of their customers ("Service
Agreements"). Under such Service Agreements the Service Organizations may
perform some or all of the following services: (a) act, directly or through an
agent, as the sole shareholder of record and nominee for all customers, (b)
maintain account records for each customer who beneficially owns Service Shares
of a Fund, (c) answer questions and handle correspondence from customers
regarding their accounts, (d) process customer orders to purchase, redeem and
exchange Service Shares of a Fund, and handle the transmission of funds
representing the customers' purchase price or redemption proceeds, (e) issue
confirmations for transactions in shares by customers, (f) provide facilities to
answer questions from prospective and existing investors about Service Shares of
a Fund, (g) receive and answer investor correspondence, including requests for
prospectuses and statements of additional information, (h) display and make
prospectuses available on the Service Organization's premises, (i) assist
customers in completing application forms, selecting dividend and other account
options and opening custody accounts with the Service Organization and (j) act
as liaison between customers and a Fund, including obtaining information from
the Fund, working with the Fund to correct errors and resolve problems and
providing statistical and other information to a Fund. As compensation for such
services, each Fund will pay each Service Organization a service fee in an
amount up to 0.50% (on an annualized basis) of the average daily net assets of
the Service Shares of such Fund attributable to or held in the name of such
Service Organization.

The amount of the service fees paid by each Fund then in existence to Service
Organizations pursuant to the Plan was as follows for the fiscal years
indicated:

During the period July 27, 1998 (commencement of operations) through December
31, 1998, the Real Estate Securities Fund paid Service Organizations $3 pursuant
to the Plan.

The Funds have adopted the Plan pursuant to Rule 12b-1 under the Act in order to
avoid any possibility that payments to the Service Organizations pursuant to the
Service Agreements might violate the Act. Rule 12b-1, which was adopted by the
SEC under the Act, regulates the circumstances under which an investment company
or series thereof may bear expenses associated with the distribution of its
shares. In particular, such an investment company or series thereof cannot
engage directly or indirectly in financing any activity which is primarily
intended to result in the sale of shares issued by the company unless it has
adopted a plan pursuant to, and complies with the other requirements of, such
Rule. The Trust believes that fees paid for the services provided in the Plan
and described above are not expenses incurred primarily for effecting the
distribution of Service Shares. However, should such payments be deemed by a
court or the SEC to be distribution expenses, such payments would be duly
authorized by the Plan.

The Glass-Steagall Act prohibits all entities which receive deposits from
engaging to any extent in the business of issuing, underwriting, selling or
distributing securities, although institutions such as national banks are
permitted to purchase and sell securities upon the order and for the account of
their customers. In addition, under some state securities laws, banks and other
financial institutions purchasing Service Shares on behalf of their customers
may be required to register as dealers. Should future legislative or
administrative action or judicial or administrative decisions or interpretations
prohibit or restrict the activities of one or more of the Service Organizations
in connection with a Fund, such Service Organizations might be required to alter
materially or discontinue the services performed under their Service Agreements.
If one or more of the Service Organizations were restricted from effecting
purchases or sales of Service Shares automatically pursuant to pre-authorized
instructions, for example, effecting such transactions on a manual basis might
affect the size and/or growth of a Fund. Any such alteration or discontinuance
of services could require the Board of Trustees to consider changing a Fund's
method of operations or providing alternative means of offering Service Shares
of the Fund to customers of such Service Organizations, in which case the
operation of such Fund, its size and/or its growth might be significantly
altered. It is not anticipated, however, that any alteration of a Fund's
operations would have any effect on the net asset value per share or result in
financial losses to any shareholder.

Conflict of interest restrictions (including the Employee Retirement Income
Security Act of 1974) may apply to a Service Organization's receipt of
compensation paid by a Fund in connection with the investment of fiduciary
assets in Service Shares of a Fund. Service Organizations, including banks
regulated by the Comptroller of the Currency, the Federal Reserve Board or the
Federal Deposit Insurance Corporation, and investment advisers and other money
managers subject to the jurisdiction of the SEC, the Department of Labor or
state securities commissions, are urged to consult their legal advisers before
investing fiduciary assets in Service Shares of a Fund. In


                                     B-125
<PAGE>
 
addition, under some state securities laws, banks and other financial
institutions purchasing Service Shares on behalf of their customers may be
required to register as dealers.

The Trustees, including a majority of the Trustees who are not interested
persons of the Trust and who have no direct or indirect financial interest in
the operation of the Plan or the related Service Agreements, most recently voted
to approve the Plan and related Service Agreements at a meeting called for the
purpose of voting on such Plan and Service Agreements on April 27, 1999. The
Plan and related Service Agreements will remain in effect until May 1, 2000 and
will continue in effect thereafter only if such continuance is specifically
approved annually by a vote of the Trustees in the manner described above. The
Plan may not be amended to increase materially the amount to be spent for the
services described therein without approval of the Service Shareholders of the
affected Fund and all material amendments of the Plan must also be approved by
the Trustees in the manner described above. The Plan may be terminated at any
time by a majority of the Trustees as described above or by a vote of a majority
of the outstanding Service Shares of the affected Fund. The Service Agreements
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Trustees as described above or by a vote of a majority of the
outstanding Service Shares of the affected Fund on not more than sixty (60)
days' written notice to any other party to the Service Agreements. The Service
Agreements will terminate automatically if assigned. So long as the Plan is in
effect, the selection and nomination of those Trustees who are not interested
persons will be committed to the discretion of the non-interested Trustees. The
Trustees have determined that, in its judgment, there is a reasonable likelihood
that the Plans will benefit the Funds and the holders of Service Shares of the
Funds.

                                   APPENDIX A

Commercial Paper Ratings

            A Standard & Poor's ("S&P") commercial paper rating is a current
assessment of the likelihood of timely payment of debt having an original
maturity of no more than 365 days. The following summarizes the rating
categories used by Standard and Poor's for commercial paper:

            "A-1" - Obligations are rated in the highest category indicating
that the obligor's capacity to meet its financial commitment on the obligation
is strong. Within this category, certain obligations are designated with a plus
sign (+). This indicates that the obligor's capacity to meet its financial
commitment on these obligations is extremely strong.

            "A-2" - Obligations are somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

            "A-3" - Obligations exhibit adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.

            "B" - Obligations are regarded as having significant speculative
characteristics. The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

            "C" - Obligations are currently vulnerable to nonpayment and are
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.

            "D" - Obligations are in payment default. The "D" rating category is
used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless S&P believes that such payments
will be made during such grace period. The "D" rating will be used upon the
filing of a bankruptcy petition or the taking of a similar action if payments on
an obligation are jeopardized.

            Moody's commercial paper ratings are opinions of the ability of
issuers to repay punctually senior debt obligations not having an original
maturity in excess of one year, unless explicitly noted. The following
summarizes the rating categories used by Moody's for commercial paper:


                                      1-A
<PAGE>
 
            "Prime-1" - Issuers (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:
leading market positions in well-established industries; high rates of return on
funds employed; conservative capitalization structure with moderate reliance on
debt and ample asset protection; broad margins in earnings coverage of fixed
financial charges and high internal cash generation; and well-established access
to a range of financial markets and assured sources of alternate liquidity.

            "Prime-2" - Issuers (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

            "Prime-3" - Issuers (or supporting institutions) have an acceptable
ability for repayment of senior short-term debt obligations. The effect of
industry characteristics and market compositions may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.

            "Not Prime" - Issuers do not fall within any of the Prime rating
categories.

            The three rating categories of Duff & Phelps for investment grade
commercial paper and short-term debt are "D-1," "D-2" and "D-3." Duff & Phelps
employs three designations, "D-1+," "D-1" and "D-1-," within the highest rating
category. The following summarizes the rating categories used by Duff & Phelps
for commercial paper:

            "D-1+" - Debt possesses the highest certainty of timely payment.
Short-term liquidity, including internal operating factors and/or access to
alternative sources of funds, is outstanding, and safety is just below risk-free
U.S. Treasury short-term obligations.

            "D-1" - Debt possesses very high certainty of timely payment.
Liquidity factors are excellent and supported by good fundamental protection
factors. Risk factors are minor.

            "D-1-" - Debt possesses high certainty of timely payment. Liquidity
factors are strong and supported by good fundamental protection factors. Risk
factors are very small.

            "D-2" - Debt possesses good certainty of timely payment. Liquidity
factors and company fundamentals are sound. Although ongoing funding needs may
enlarge total financing requirements, access to capital markets is good. Risk
factors are small.

            "D-3" - Debt possesses satisfactory liquidity and other protection
factors qualify issues as to investment grade. Risk factors are larger and
subject to more variation. Nevertheless, timely payment is expected.


                                      2-A
<PAGE>
 
            "D-4" - Debt possesses speculative investment characteristics.
Liquidity is not sufficient to insure against disruption in debt service.
Operating factors and market access may be subject to a high degree of
variation.

            "D-5" - Issuer has failed to meet scheduled principal and/or
interest payments.

            Fitch IBCA short-term ratings apply to debt obligations that have
time horizons of less than 12 months for most obligations, or up to three years
for U.S. public finance securities. The following summarizes the rating
categories used by Fitch IBCA for short-term obligations:

            "F1" - Securities possess the highest credit quality. This
designation indicates the strongest capacity for timely payment of financial
commitments and may have an added "+" to denote any exceptionally strong credit
feature.

            "F2" - Securities possess good credit quality. This designation
indicates a satisfactory capacity for timely payment of financial commitments,
but the margin of safety is not as great as in the case of the higher ratings.

            "F3" - Securities possess fair credit quality. This designation
indicates that the capacity for timely payment of financial commitments is
adequate; however, near-term adverse changes could result in a reduction to
non-investment grade.

            "B" - Securities possess speculative credit quality. This
designation indicates minimal capacity for timely payment of financial
commitments, plus vulnerability to near-term adverse changes in financial and
economic conditions.

            "C" - Securities possess high default risk. This designation
indicates that default is a real possibility and that the capacity for meeting
financial commitments is solely reliant upon a sustained, favorable business and
economic environment.

            "D" - Securities are in actual or imminent payment default.

            Thomson BankWatch short-term ratings assess the likelihood of an
untimely payment of principal and interest of debt instruments with original
maturities of one year or less. The following summarizes the ratings used by
Thomson BankWatch:

            "TBW-1" - This designation represents Thomson BankWatch's highest
category and indicates a very high likelihood that principal and interest will
be paid on a timely basis.

            "TBW-2" - This designation represents Thomson BankWatch's
second-highest category and indicates that while the degree of safety regarding
timely repayment of principal and interest is strong, the relative degree of
safety is not as high as for issues rated "TBW-1."


                                      3-A
<PAGE>
 
            "TBW-3" - This designation represents Thomson BankWatch's lowest
investment-grade category and indicates that while the obligation is more
susceptible to adverse developments (both internal and external) than those with
higher ratings, the capacity to service principal and interest in a timely
fashion is considered adequate.

            "TBW-4" - This designation represents Thomson BankWatch's lowest
rating category and indicates that the obligation is regarded as non-investment
grade and therefore speculative.

Corporate and Municipal Long-Term Debt Ratings

            The following summarizes the ratings used by Standard & Poor's for
corporate and municipal debt:

            "AAA" - An obligation rated "AAA" has the highest rating assigned by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is extremely strong.

            "AA" - An obligation rated "AA" differs from the highest rated
obligations only in small degree. The obligor's capacity to meet its financial
commitment on the obligation is very strong.

            "A" - An obligation rated "A" is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher-rated categories. However, the obligor's capacity to meet
its financial commitment on the obligation is still strong.

            "BBB" - An obligation rated "BBB" exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

            Obligations rated "BB," "B," "CCC," "CC" and "C" are regarded as
having significant speculative characteristics. "BB" indicates the least degree
of speculation and "C" the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.

            "BB" - An obligation rated "BB" is less vulnerable to nonpayment
than other speculative issues. However, it faces major ongoing uncertainties or
exposure to adverse business, financial or economic conditions which could lead
to the obligor's inadequate capacity to meet its financial commitment on the
obligation.

            "B" - An obligation rated "B" is more vulnerable to nonpayment than
obligations rated "BB", but the obligor currently has the capacity to meet its
financial commitment on the


                                      4-A
<PAGE>
 
obligation. Adverse business, financial or economic conditions will likely
impair the obligor's capacity or willingness to meet its financial commitment on
the obligation.

            "CCC" - An obligation rated "CCC" is currently vulnerable to
nonpayment, and is dependent upon favorable business, financial and economic
conditions for the obligor to meet its financial commitment on the obligation.
In the event of adverse business, financial, or economic conditions, the obligor
is not likely to have the capacity to meet its financial commitment on the
obligation.

            "CC" - An obligation rated "CC" is currently highly vulnerable to
nonpayment.

            "C" - The "C" rating may be used to cover a situation where a
bankruptcy petition has been filed or similar action has been taken, but
payments on this obligation are being continued.

            "D" - An obligation rated "D" is in payment default. The "D" rating
category is used when payments on an obligation are not made on the date due
even if the applicable grace period has 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 or the taking of a similar action
if payments on an obligation are jeopardized.

            PLUS (+) OR MINUS (-) - The ratings from "AA" through "CCC" may be
modified by the addition of a plus or minus sign to show relative standing
within the major rating categories.

            "r" - This symbol is attached to the ratings of instruments with
significant noncredit risks. It highlights risks to principal or volatility of
expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk - such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

            The following summarizes the ratings used by Moody's for corporate
and municipal long-term debt:

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

            "Aa" - Bonds are judged to be of high quality by all standards.
Together with the "Aaa" group they comprise what are generally known as
high-grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in "Aaa" securities or


                                      5-A
<PAGE>
 
fluctuation of protective elements may be of greater amplitude or there may be
other elements present which make the long-term risk appear somewhat larger than
the "Aaa" securities.

            "A" - Bonds 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.

            "Baa" - Bonds 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.

            "Ba," "B," "Caa," "Ca," and "C" - Bonds that possess one of these
ratings provide questionable protection of interest and principal ("Ba"
indicates speculative elements; "B" indicates a general lack of characteristics
of desirable investment; "Caa" are of poor standing; "Ca" represents obligations
which are speculative in a high degree; and "C" represents the lowest rated
class of bonds). "Caa," "Ca" and "C" bonds may be in default.

            Con. (---) - Bonds for which the security depends upon the
completion of some act or the fulfillment of some condition are rated
conditionally. These are bonds secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operating experience, (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

            Note: Moody's applies numerical modifiers 1, 2, and 3 in each
generic rating classification from "Aa" through "Caa". The modifier 1 indicates
that the obligation ranks in the higher end of its generic rating category; the
modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking
in the lower end of its generic rating category.

            The following summarizes the long-term debt ratings used by Duff &
Phelps for corporate and municipal long-term debt:

            "AAA" - Debt is considered to be of the highest credit quality. The
risk factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

            "AA" - Debt is considered to be of high credit quality. Protection
factors are strong. Risk is modest but may vary slightly from time to time
because of economic conditions.

            "A" - Debt possesses protection factors which are average but
adequate. However, risk factors are more variable in periods of greater economic
stress.


                                      6-A
<PAGE>
 
            "BBB" - Debt possesses below-average protection factors but such
protection factors are still considered sufficient for prudent investment.
Considerable variability in risk is present during economic cycles.

            "BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of these
ratings is considered to be below investment grade. Although below investment
grade, debt rated "BB" is deemed likely to meet obligations when due. Debt rated
"B" possesses the risk that obligations will not be met when due. Debt rated
"CCC" is well below investment grade and has considerable uncertainty as to
timely payment of principal, interest or preferred dividends. Debt rated "DD" is
a defaulted debt obligation, and the rating "DP" represents preferred stock with
dividend arrearages.

            To provide more detailed indications of credit quality, the "AA,"
"A," "BBB," "BB" and "B" ratings may be modified by the addition of a plus (+)
or minus (-) sign to show relative standing within these major categories.

            The following summarizes the ratings used by Fitch IBCA for
corporate and municipal bonds:

            "AAA" - Bonds considered to be investment grade and of the highest
credit quality. These ratings denote the lowest expectation of credit risk and
are assigned only in case of exceptionally strong capacity for timely payment of
financial commitments. This capacity is highly unlikely to be adversely affected
by foreseeable events.

            "AA" - Bonds considered to be investment grade and of very high
credit quality. These ratings denote a very low expectation of credit risk and
indicate very strong capacity for timely payment of financial commitments. This
capacity is not significantly vulnerable to foreseeable events.

            "A" - Bonds considered to be investment grade and of high credit
quality. These ratings denote a low expectation of credit risk and indicate
strong capacity for timely payment of financial commitments. This capacity may,
nevertheless, be more vulnerable to changes in circumstances or in economic
conditions than is the case for higher ratings.

            "BBB" - Bonds considered to be investment grade and of good credit
quality. These ratings denote that there is currently a low expectation of
credit risk. The capacity for timely payment of financial commitments is
considered adequate, but adverse changes in circumstances and in economic
conditions are more likely to impair this capacity.

            "BB" - Bonds considered to be speculative. These ratings indicate
that there is a possibility of credit risk developing, particularly as the
result of adverse economic changes over time; however, business or financial
alternatives may be available to allow financial commitments to be met.
Securities rated in this category are not investment grade.


                                      7-A
<PAGE>
 
            "B" - Bonds are considered highly speculative. These ratings
indicate that significant credit risk is present, but a limited margin of safety
remains. Financial commitments are currently being met; however, capacity for
continued payment is contingent upon a sustained, favorable business and
economic environment.

            "CCC", "CC", "C" - Bonds have high default risk. Default is a real
possibility, and capacity for meeting financial commitments is solely reliant
upon sustained, favorable business or economic developments. "CC" ratings
indicate that default of some kind appears probable, and "C" ratings signal
imminent default.

            "DDD," "DD" and "D" - Bonds are in default. Securities are not
meeting obligations and are extremely speculative. "DDD" designates the highest
potential for recovery of amounts outstanding on any securities involved and "D"
represents the lowest potential for recovery.

            To provide more detailed indications of credit quality, the Fitch
IBCA ratings from and including "AA" to "B" may be modified by the addition of a
plus (+) or minus (-) sign to show relative standing within these major rating
categories.

            Thomson BankWatch assesses the likelihood of an untimely repayment
of principal or interest over the term to maturity of long term debt and
preferred stock which are issued by United States commercial banks, thrifts and
non-bank banks; non-United States banks; and broker-dealers. The following
summarizes the rating categories used by Thomson BankWatch for long-term debt
ratings:

            "AAA" - This designation indicates that the ability to repay
principal and interest on a timely basis is extremely high.

            "AA" - This designation indicates a very strong ability to repay
principal and interest on a timely basis, with limited incremental risk compared
to issues rated in the highest category.

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

            "BBB" - This designation represents the lowest investment-grade
category and indicates an acceptable capacity to repay principal and interest.
Issues rated "BBB" are more vulnerable to adverse developments (both internal
and external) than obligations with higher ratings.

            "BB," "B," "CCC," and "CC," - These designations are assigned by
Thomson BankWatch to non-investment grade long-term debt. Such issues are
regarded as having speculative characteristics regarding the likelihood of
timely payment of principal and interest. "BB" indicates the lowest degree of
speculation and "CC" the highest degree of speculation.


                                      8-A
<PAGE>
 
            "D" - This designation indicates that the long-term debt is in
default.

            PLUS (+) OR MINUS (-) - The ratings from "AAA" through "CC" may
include a plus or minus sign designation which indicates where within the
respective category the issue is placed.

Municipal Note Ratings

            A Standard and Poor's rating reflects the liquidity concerns and
market access risks unique to notes due in three years or less. The following
summarizes the ratings used by Standard & Poor's Ratings Group for municipal
notes:

            "SP-1" - The issuers of these municipal notes exhibit a strong
capacity to pay principal and interest. Those issues determined to possess very
strong characteristics are given a plus (+) designation.

            "SP-2" - The issuers of these municipal notes exhibit satisfactory
capacity to pay principal and interest, with some vulnerability to adverse
financial and economic changes over the term of the notes.

            "SP-3" - The issuers of these municipal notes exhibit speculative
capacity to pay principal and interest.

            Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade ("VMIG"). Such
ratings recognize the differences between short-term credit risk and long-term
risk. The following summarizes the ratings by Moody's Investors Service, Inc.
for short-term notes:

            "MIG-1"/"VMIG-1" - This designation denotes best quality. There is
present strong protection by established cash flows, superior liquidity support
or demonstrated broad-based access to the market for refinancing.

            "MIG-2"/"VMIG-2" - This designation denotes high quality, with
margins of protection that are ample although not so large as in the preceding
group.

            "MIG-3"/"VMIG-3" - This designation denotes favorable quality, with
all security elements accounted for but lacking the undeniable strength of the
preceding grades. Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.


                                      9-A
<PAGE>
 
            "MIG-4"/"VMIG-4" - This designation denotes adequate quality.
Protection commonly regarded as required of an investment security is present
and although not distinctly or predominantly speculative, there is specific
risk.

            "SG" - This designation denotes speculative quality. Debt
instruments in this category lack of margins of protection.

            Fitch IBCA and Duff & Phelps use the short-term ratings described
under Commercial Paper Ratings for municipal notes.

                  BUSINESS PRINCIPLES OF GOLDMAN, SACHS & CO.

      Goldman Sachs is noted for its Business Principles, which guide all of the
firm's activities and serve as the basis for its distinguished reputation among
investors worldwide.

      Our client's interests always come first. Our experience shows that if we
serve our clients well, our own success will follow.

        Our assets are our people, capital, and reputation. If any of these is
ever diminished, the last is the most difficult to restore. We are dedicated to
complying fully with the letter and spirit of the laws, rules and ethical
principles that govern us. Our continued success depends upon unswerving
adherence to this standard.

      We take great pride in the professional quality of our work. We have an
uncompromising determination to achieve excellence in everything we undertake.
Though we may be involved in a wide variety and heavy volume of activity, we
would, if it came to a choice, rather be best than biggest.

      We stress creativity and imagination in everything we do. While
recognizing that the old way may still be the best way, we constantly strive to
find a better solution to a client's problems. We pride ourselves on having
pioneered many of the practices and techniques that have become standard in the
industry.

      We make an unusual effort to identify and recruit the very best person for
every job. Although our activities are measured in billions of dollars, we
select our people one by one. In a service business, we know that without the
best people, we cannot be the best firm.

      We offer our people the opportunity to move ahead more rapidly than is
possible at most other places. We have yet to find limits to the responsibility
that our best people are able to assume. Advancement depends solely on ability,
performance and contribution to the Firm's success, without regard to race,
color, religion, sex, age, national origin, disability, sexual orientation, or
any other impermissible criterion or circumstance.

      We stress teamwork in everything we do. While individual creativity is
always encouraged, we have found that team effort often produces the best
results. We have no room for those who put their personal interests ahead of the
interests of the Firm and its clients.

      The dedication of our people to the Firm and the intense effort they give
their jobs are greater than one finds in most other organizations. We think that
this is an important part of our success.

       Our profits are a key to our success. They replenish our capital and
attract and keep our best people. It is our practice to share our profits
generously with all who help create them. Profitability is crucial to our
future.

      We consider our size an asset that we try hard to preserve. We want to be
big enough to undertake the largest project that any of our clients could
contemplate, yet small enough to


                                      1-B
<PAGE>
 
maintain the loyalty, the intimacy and the esprit de corps that we all treasure
and that contribute greatly to our success.

      We constantly strive to anticipate the rapidly changing needs of our
clients and to develop new services to meet those needs. We know that the world
of finance will not stand still and that complacency can lead to extinction.

      We regularly receive confidential information as part of our normal client
relationships. To breach a confidence or to use confidential information
improperly or carelessly would be unthinkable.

      Our business is highly competitive, and we aggressively seek to expand our
client relationships. However, we must always be fair competitors and must never
denigrate other firms.

      Integrity and honesty are the heart of our business. We expect our people
to maintain high ethical standards in everything they do, both in their work for
the firm and in their personal lives.

                             Statement of Intention
                       (applicable only to Class A shares)

      If a shareholder anticipates purchasing $50,000 or more of Class A Shares
of a Fund alone or in combination with Class A Shares of another Goldman Sachs
Fund within a 13-month period, the shareholder may obtain shares of the Fund at
the same reduced sales charge as though the total quantity were invested in one
lump sum by checking and filing the Statement of Intention in the Account
Application. Income dividends and capital gain distributions taken in additional
shares will not apply toward the completion of the Statement of Intention.

      To ensure that the reduced price will be received on future purchases, the
investor must inform Goldman Sachs that the Statement of Intention is in effect
each time shares are purchased. Subject to the conditions mentioned below, each
purchase will be made at the public offering price applicable to a single
transaction of the dollar amount specified on the Account Application. The
investor makes no commitment to purchase additional shares, but if the
investor's purchases within 13 months plus the value of shares credited toward
completion do not total the sum specified, the investor will pay the increased
amount of the sales charge prescribed in the Escrow Agreement.

                                Escrow Agreement

      Out of the initial purchase (or subsequent purchases if necessary), 5% of
the dollar amount specified on the Account Application will be held in escrow by
the Transfer Agent in the form of shares registered in the investor's name. All
income dividends and capital gains distributions on escrowed shares will be paid
to the investor or to his or her order. When the minimum investment so specified
is completed (either prior to or by the end of the 13th month), the investor
will be notified and the escrowed shares will be released.

      If the intended investment is not completed, the investor will be asked to
remit to Goldman Sachs any difference between the sales charge on the amount
specified and on the amount actually attained. If the investor does not within
20 days after written request by Goldman Sachs pay such difference in the sales
charge, the Transfer Agent will redeem, pursuant to the authority given by the
investor in the Account Application, an appropriate number of the escrowed
shares in order to realize such difference. Shares remaining after any such
redemption will be released by the Transfer Agent.

                                  INTRODUCTION

      Goldman Sachs Trust (the "Trust") is an open-end management investment
company. The Trust is organized as a Delaware business trust, and is a successor
to a Massachusetts business trust that was combined with the Trust on April 30,
1997. The following series of the Trust are described in this Additional
Statement: Goldman Sachs Conservative Strategy Portfolio ("Conservative Strategy
Portfolio"), Goldman Sachs Balanced Strategy Portfolio ("Balanced Strategy
Portfolio"), Goldman Sachs Growth and Income Strategy Portfolio ("Growth and
Income Strategy Portfolio"), Goldman Sachs Growth Strategy Portfolio ("Growth
Strategy Portfolio") and Goldman Sachs Aggressive Growth Strategy Portfolio
("Aggressive Growth Strategy Portfolio") (each referred to herein as a
"Portfolio" and collectively referred to as the "Portfolios"). The Trust assumed
its current name on March 22, 1991. The Trustees of the Trust have authority
under the Declaration of Trust to create and classify shares into separate
series and to classify and reclassify any series of shares into one or more
classes without further action by shareholders. Pursuant thereto, the Trustees
have created the Portfolios and other series. Each Portfolio is each authorized
to issue five classes of shares: Institutional Shares, Service Shares, Class A
Shares, Class B Shares and Class C Shares. Additional series and classes may be
added in the future from time to time. No shares of the Conservative Strategy
Portfolio were offered during the Fiscal Year ended December 31, 1998.

      Each Portfolio is a separately managed, diversified mutual fund with its
own investment objectives and policies. Each Portfolio has been constructed as a
"fund of funds," which means that it pursues its investment objective primarily
by allocating its investments among other investment portfolios of the Trust
(the "Underlying Funds").

      Goldman Sachs Asset Management ("GSAM"), a separate operating division of
Goldman, Sachs & Co. ("Goldman Sachs"), serves as investment adviser to each
Portfolio. GSAM is sometimes referred to herein as the "Adviser." Goldman Sachs
serves as each Portfolio's distributor and transfer agent. Each Portfolio's
custodian is State Street Bank and Trust Company ("State Street").

                       INVESTMENT OBJECTIVES AND POLICIES

      Normally, each of the Portfolios will be predominantly invested in shares
of the Underlying Funds. These Underlying Funds currently consist of the: the
Growth and Income Fund, CORE Large Cap Value Fund, CORE U.S. Equity Fund, CORE
Large Cap Growth Fund, CORE Small Cap Equity Fund, Capital Growth Fund, Mid Cap
Value Fund, Small Cap Value Fund, Real Estate Securities Fund, CORE
International Equity Fund, International Equity Fund, European Equity Fund,
Japanese Equity Fund, International Small Cap Fund, Emerging Markets Equity
Fund, and Asia Growth Fund, (the "Underlying Equity Funds"); Adjustable Rate
Government Fund, Short Duration Government Fund, Government Income Fund, Core
Fixed Income Fund, Global Income Fund and High Yield Fund (the "Underlying
Fixed-Income Funds") and the Financial Square Prime Obligations Fund. The value
of the Underlying Funds' investments, and the net asset value of the shares of
both the Underlying Funds and the Portfolios will fluctuate with market,
economic and, to the extent applicable, foreign exchange conditions, so that an
investment in any of the Portfolios may be worth more or less when redeemed than
when purchased. The following description provides additional information
regarding the Underlying Funds and the types of investments that the Underlying
Funds may make.

Description of Underlying Funds

Growth and Income Fund

      Objectives. This Fund seeks long-term growth of capital and growth of
income.

      Primary Investment Focus. This Fund invests, under normal circumstances,
at least 65% of its total assets in equity securities that its investment
adviser considers to have favorable prospects for capital appreciation and/or
dividend-paying ability.

      Other. This Fund may invest up to 35% of its total assets in fixed-income
securities, such as corporate debt and bank obligations, that offer the
potential to further the Fund's investment objective. In addition, although the
Fund will invest primarily in publicly traded U.S. securities, it may invest up
to 25% of its total assets in foreign securities, including securities of
issuers in emerging countries and securities quoted in foreign currencies.

CORE Large Cap Value Fund

      Objective. This Fund seeks long-term growth of capital and dividend
income. The Fund seeks this objective through a broadly diversified portfolio of
equity securities of large-cap U.S. issuers that are selling at low to modest
valuations relative to general market measures such as earnings, book value and
other fundamental accounting measures, and that are expected to have favorable
prospects for capital appreciation and/or dividend-paying ability.

      Primary Investment Focus. This Fund invests, under normal circumstances,
at least 90% of its total assets in equity securities of U.S. issuers, including
foreign issuers that are traded in the United States. The Fund's investments are
selected using both a variety of quantitative techniques and fundamental
research in seeking to maximize the Fund's expected return, while maintaining
risk, style, capitalization and industry characteristics similar to the Russell
1000 Value Index. The Fund seeks a portfolio composed of companies with above
average capitalizations and low to moderate valuations as measured by
price/earnings ratios, book value and other fundamental accounting measures.

      Other. The Fund's investments in fixed-income securities are limited to
securities that are considered cash equivalents.

CORE U.S. Equity Fund

      Objective. This Fund seeks long-term growth of capital and dividend
income. The Fund seeks this objective through a broadly diversified portfolio of
large-cap and blue chip equity securities representing all major sectors of the
U.S. economy.

      Primary Investment Focus. This Fund invests, under normal circumstances,
at least 90% of its total assets in equity securities of U.S. issuers, including
foreign issuers that are traded in the United States. The Fund's investments are
selected using both a variety of quantitative techniques and fundamental
research in seeking to maximize the Fund's expected return, while maintaining
risk, style, capitalization and industry characteristics similar to the S&P 500
Index. The Fund seeks a broad representation in most major sectors of the U.S.
economy and a portfolio composed of companies with average long-term earnings
growth expectations and dividend yields.


                                      B-5
<PAGE>
 
      Other. The Fund's investments in fixed-income securities are limited to
securities that are considered cash equivalents.

CORE Large Cap Growth Fund

      Objective. This Fund seeks long-term growth of capital. The Fund seeks
this objective through a broadly diversified portfolio of equity securities of
large cap U.S. issuers that are expected to have better prospects for earnings
growth than the growth rate of the general domestic economy. Dividend income is
a secondary consideration.

      Primary Investment Focus. This Fund invests, under normal circumstances,
at least 90% of its total assets in equity securities of U.S. issuers, including
foreign issuers that are traded in the United States. The Fund's investment
adviser emphasizes a company's growth prospects in analyzing equity securities
to be purchased by the Fund. The Fund's investments are selected using both a
variety of quantitative techniques and fundamental research in seeking to
maximize the Fund's expected return, while maintaining risk, style,
capitalization and industry characteristics similar to the Russell 1000 Growth
Index. The Fund seeks a portfolio composed of companies with above average
capitalizations and earnings growth expectations and below average dividend
yields.

      Other. The Fund's investments in fixed-income securities are limited to
securities that are considered cash equivalents.

CORE Small Cap Equity Fund

      Objective. This Fund seeks long-term growth of capital. The Fund seeks
this objective through a broadly diversified portfolio of equity securities of
U.S. issuers which are included in the Russell 2000 Index at the time of
investment.

      Primary Investment Focus. This Fund invests, under normal circumstances,
at least 90% of its total assets in equity securities of U.S. issuers, including
foreign issuers that are traded in the United States. The Fund's investments are
selected using both a variety of quantitative techniques and fundamental
research in seeking to maximize the Fund's expected return, while maintaining
risk, style, capitalization and industry characteristics similar to the Russell
2000 Index. The Fund seeks a portfolio composed of companies with small market
capitalizations, strong expected earnings growth and momentum, and better
valuation and risk characteristics than the Russell 2000 Index. If the issuer of
a portfolio security held by the Fund is no longer included in the Russell 2000
Index, the Fund may, but is not required to, sell the security.

      Other. The Fund's investments in fixed-income securities are limited to
securities that are considered cash equivalents.

Capital Growth Fund

      Objective. This Fund seeks long-term growth of capital.

      Primary Investment Focus. This Fund invests, under normal circumstances,
at least 90% of its total assets in equity securities. The Fund seeks to achieve
its investment objective by investing in a diversified portfolio of equity
securities that are considered by its investment adviser to have long-term
capital appreciation potential.


                                      B-6
<PAGE>
 
      Other. Although this Fund will invest primarily in publicly traded U.S.
securities, it may invest up to 10% of its total assets in foreign securities,
including securities of issuers in emerging countries and securities quoted in
foreign currencies.

Mid Cap Value Fund

      Objective. This Fund seeks long-term capital appreciation.

      Primary Investment Focus. This Fund invests, under normal circumstances,
substantially all of its assets in equity securities and at least 65% of its
total assets in equity securities of mid-cap companies with public stock market
capitalizations (based upon shares available for trading on an unrestricted
basis) within the range of the market capitalization of companies constituting
the Russell Midcap Index at the time of investment (currently between $400
million and $16 billion). If the capitalization of an issuer decreases below
$400 million or increases above $16 billion after purchase, the Fund may, but is
not required to, sell the securities. Dividend income, if any, is an incidental
consideration.

      Other. This Fund may invest up to 35% of its total assets in fixed-income
securities, such as corporate debt and bank obligations. In addition, although
the Fund will invest primarily in publicly traded U.S. securities, it may invest
up to 25% of its total assets in foreign securities, including securities of
issuers in emerging countries and securities quoted in foreign currencies.

Small Cap Value Fund

      Objective. This Fund seeks long-term growth of capital.

      Primary Investment Focus. This Fund invests, under normal circumstances,
at least 65% of its total assets in equity securities of companies with public
stock market capitalizations of $1 billion or less at the time of investment.
Under normal circumstances, the Fund's investment horizon for ownership of
stocks will be two to three years. Dividend income, if any, is an incidental
consideration. If the market capitalization of a company held by the Fund
increases above $1 billion, the Fund may, consistent with its investment
objective, continue to hold the security.

      Small Capitalization Companies. This Fund invests in companies which its
investment adviser believes are well managed niche businesses that have the
potential to achieve high or improving returns on capital and/or above average
sustainable growth. The Fund may invest in securities of small market
capitalization companies which may have experienced financial difficulties.
Investments may also be made in companies that are in the early stages of their
life and that the Fund's investment adviser believes have significant growth
potential. The investment adviser believes that the companies in which the Fund
may invest offer greater opportunity for growth of capital than larger, more
mature, better known companies. However, investments in such small market
capitalization companies involve special risks.

      Other. This Fund may invest in the aggregate up to 35% of its total assets
in companies with public stock market capitalizations in excess of $1 billion at
the time of investment and in fixed-income securities. In addition, although the
Fund will invest primarily in publicly traded U.S. securities, it may invest up
to 25% of its total assets in foreign securities, including securities of
issuers in emerging countries and securities quoted in foreign currencies.

Real Estate Securities Fund

      Objective. This Fund seeks total return comprised of long-term growth of
capital and dividend income.

      Primary Investment Focus. This Fund will invest, under normal
circumstances substantially all and at least 80% of its total assets in a
diversified portfolio of equity securities of issuers that are primarily engaged
in or related to the real estate industry. The Fund expects that a substantial
portion of its assets will be invested in REITs and real estate industry
companies. A "real estate industry company" is a company that derives at least
50% of its gross revenues or net profits from the ownership, development,
construction, financing, management or sale of commercial, industrial or
residential real estate or interests therein.

      The Fund's investment strategy is based on the premise that property
market fundamentals are the primary determinant of growth, underlying the
success of companies in the real estate industry. The Fund's investment adviser
focuses on companies that can achieve sustainable growth in cash flow and
dividend paying capability. The investment adviser attempts to purchase
securities so that its underlying portfolio will be diversified geographically
and by property type.

      Investing in REITs involves certain unique risks in addition to those
risks associated with investing in the real estate industry in general. Equity
REITs may be affected by changes in the value of the underlying property owned
by the REITs.

      Mortgage REITs may be affected by the quality of any credit extended.
REITs are dependent upon management skill, may not be diversified, and are
subject to heavy cash flow dependency, default by borrowers and
self-liquidation. REITs are also subject to the possibilities of failing to
qualify for tax free pass-through of income and failing to maintain their
exemptions from investment company registration. REITS whose underlying
properties are concentrated in a particular industry or geographic region are
also subject to risks affecting such industries and regions.

      REITs (especially mortgage REITs) are also subject to interest rate risks.
When interest rates decline, the value of a REIT's investment in fixed rate
obligations can be expected to rise. Conversely, when interest rates rise, the
value of a REIT's investment in fixed rate obligations can be expected to
decline.

      Shares of REITs. The Fund may invest without limitation in shares of
REITs. REITs are pooled investment vehicles that invest primarily in either real
estate or real estate related loans. REITs are generally classified as equity
REITs, mortgage REITs or a combination of equity and mortgage REITs. Equity
REITs invest the majority of their assets directly in real property and derive
income primarily from the collection of rents. Equity REITs can also realize
capital gains by selling properties that have appreciated in value. Mortgage
REITs invest the majority of their assets in real estate mortgages and derive
income from the collection of interest payments. Similar to investment companies
such as the Fund, REITs are not taxed on income distributed to shareholders
provided they comply with several requirements of the Internal Revenue Code of
1986, as amended (the "Code"). The Fund will indirectly bear its proportionate
share of expenses incurred by REITs in which the Fund invests in addition to the
expenses directly by the Fund.

      Other. This Fund may invest up to 20% of its total assets in fixed-income
securities, such as corporate debt and bank obligations, that offer the
potential to further the Fund's investment objectives. In


                                      B-8
<PAGE>
 
addition, although the Fund will invest primarily in publicly traded U.S.
securities, it may invest up to 15% of its total assets in foreign securities,
including securities of issuers in emerging countries and securities quoted in
foreign currencies.

CORE International Equity Fund

      Objective. This Fund seeks long-term growth of capital. The Fund seeks
this objective through a broadly diversified portfolio of equity securities of
large cap companies that are organized outside the United States or whose
securities are principally traded outside the United States.

      Primary Investment Focus. This Fund invests, under normal circumstances,
at least 90% of its total assets in equity securities of companies that are
organized outside the United States or whose securities are principally traded
outside the United States.

      The Fund may allocate its assets among countries as determined by its
investment adviser from time to time, provided the Fund's assets are invested in
at least three foreign countries. The Fund may invest in securities of issuers
in countries with emerging markets or economies which involve certain risks
which are not present in investments in more developed countries.

      The Fund seeks broad representation of large cap issuers across major
countries and sectors of the international economy. The Fund's investments are
selected using both a variety of quantitative techniques and fundamental
research in seeking to maximize the Fund's expected return, while maintaining
risk, style, capitalization and industry characteristics similar to the EAFE
Index. In addition, the Fund seeks a portfolio composed of companies with
attractive valuations and stronger momentum characteristics than the EAFE Index.

      Other. The Fund's investments in fixed-income securities are limited to
securities that are considered to be cash equivalents.

International Equity Fund

      Objective. This Fund seeks long-term capital appreciation.

      Primary Investment Focus. This Fund invests, under normal circumstances,
substantially all, and at least 65% of its total assets in equity securities of
companies that are organized outside the United States or whose securities are
principally traded outside the United States. The Fund intends to invest in
companies with public stock market capitalizations that are larger than $1
billion at the time of investment.

      The Fund may allocate its assets among countries as determined by its
investment adviser from time to time provided that the Fund's assets are
invested in at least three foreign countries.

      The Fund expects to invest a substantial portion of its assets in the
securities of issuers located in the developed countries of Western Europe and
in Japan. However, the Fund may also invest in the securities of issuers located
in Australia, Canada, New Zealand and emerging countries. Currently, emerging
countries include among others, most Latin American, African, Asian and Eastern
European nations. Many of the emerging countries in which the Fund may invest
involve risks that are not present in investments in more developed countries.


                                      B-9
<PAGE>
 
      Other. Up to 35% of the Fund's total assets may be invested in
fixed-income securities, such as corporate debt and bank obligations.

European Equity Fund

      Objective. This Fund seeks long-term capital appreciation.

      Primary Investment Focus. The Fund invests, under normal circumstances,
substantially all, and at least 65% of its total assets in equity securities of
European companies. Because of its focus, the Fund will be more susceptible to
European economic, market, political and local risks than a fund that is more
geographically diversified. A European issuer is a company that either: (i) has
a class of its securities whose principal securities markets is in a European
country; (ii) derives 50% or more of its total revenue from goods produced,
sales made or services performed in one or more of the European countries; (iii)
maintains 50% or more of its assets in one or more of the European countries; or
(iv) is organized under the laws of, or has a principal office in, a European
country. The Fund may allocate its assets among different countries as
determined by its investment adviser from time to time, provided that the Fund's
assets are invested in at least three European countries. It is currently
anticipated that a majority of the Fund's assets will be invested in the equity
securities of large cap companies located in the developed countries of Western
Europe. However, the Fund may also invest, without limit, in mid cap companies
and small cap companies, as well as companies located in emerging countries.
Currently, emerging countries include among others, most Latin American,
African, Asian, most Eastern European nations, including the states that
formerly comprised the Soviet Union and Yugoslavia.

      Other. The Fund may invest in the aggregate up to 35% of its total assets
in equity securities of non-European countries and in fixed-income securities,
such as corporate debt and bank obligations.

Japanese Equity Fund

      Objective. This Fund seeks long-term capital appreciation.

      Primary Investment Focus. The Fund invests, under normal circumstances,
substantially all, and at least 65% of its total assets in equity securities of
Japanese companies. A Japanese issuer is a company that either: (i) has a class
of its securities whose principal securities markets is in Japan; (ii) is
organized under the laws of, or has a principal office in Japan; (iii) derives
50% or more of its total revenue from goods produced, sales made or services
performed in Japan; or (iv) maintains 50% of more of its assets in Japan. The
Fund's concentration in Japanese companies will expose it to the risk of adverse
social, political and economic events which occur in Japan or affect the
Japanese markets.

      Other. The Fund may invest in the aggregate up to 35% of its total assets
in equity securities of non-Japanese companies and in fixed-income securities,
such as corporate debt and bank obligations. Many of the emerging countries in
which the Fund may invest involve risks that are not present in investments in
more developed countries.

International Small Cap Fund

      Objective. This Fund seeks long-term capital appreciation.

      Primary Investment Focus. The Fund invests, under normal circumstances,
substantially all, and at least 65% of its total assets in equity securities of
companies with public stock market capitalizations of $1


                                      B-10
<PAGE>
 
billion or less at the time of investment that are organized outside the U.S. or
whose securities are principally traded outside the U.S. The Fund may allocate
its assets among countries as determined by its investment adviser from time to
time provided that the Fund's assets are invested in at least three foreign
countries. The Fund expects to invest a substantial portion of its assets in
small cap securities of companies in the developed countries of Western Europe,
Japan and Asia. However, the Fund may also invest in the securities of issuers
located in Australia, Canada, New Zealand and the emerging countries. Currently,
emerging countries include, among others, most Latin American, African, Asian
and Eastern European nations. Many of the emerging countries in which the Fund
may invest involve risks which are not present in investments in more developed
countries.

      Other. The Fund may invest in the aggregate up to 35% of its total assets
in equity securities of larger cap companies with public stock market
capitalizations of more than $1 billion at the time of investment and in
fixed-income securities, such as corporate debt and bank obligations. If the
market capitalization of a company held by the Fund increases above $1 billion,
the Fund may, consistent with its investment objective, continue to hold the
security.

Emerging Markets Equity Fund

      Objective. This Fund seeks long-term capital appreciation.

      Primary Investment Focus. This Fund invests, under normal circumstances,
substantially all, and at least 65% of its total assets in equity securities of
emerging country issuers. The investment adviser may consider classifications by
the World Bank, the International Finance Corporation or the United Nations and
its agencies in determining whether a country is emerging or developed.
Currently, emerging countries include, among others, most Latin American,
African, Asian and Eastern European nations. The Fund's investment adviser
currently intends that the Fund's investment focus will be in the following
emerging countries as well as any other emerging country to the extent that
foreign investors are permitted by applicable law to make such investments:
Argentina, Botswana, Brazil, Chile, China, Colombia, the Czech Republic, Egypt,
Greece, Hong Kong, Hungary, India, Indonesia, Israel, Jordan, Kenya, Malaysia,
Mexico, Morocco, Pakistan, Peru, the Philippines, Poland, Portugal, Russia,
Singapore, South Africa, South Korea, Sri Lanka, Taiwan, Thailand, Turkey,
Venezuela and Zimbabwe.

      An emerging country issuer is any company that either: (i) derives 50% or
more of its total revenue from goods produced, sales made or services performed
in one or more emerging countries; (ii) is organized under the laws of, or has a
principal office in, an emerging country; (iii) maintains 50% or more of its
assets in one or more of the emerging countries; or (iv) has a class of its
securities whose principal securities markets is in an emerging country.

      Under normal circumstances, this Fund maintains investments in at least
six emerging countries, and will not invest more than 35% of its total assets in
securities of issuers in any one emerging country. Allocation of the Fund's
investments will depend upon the relative attractiveness of the emerging country
markets and particular issuers. In addition, macro-economic factors and the
portfolio managers' and Goldman Sachs economists' views of the relative
attractiveness of emerging countries and currencies are considered in allocating
the Fund's assets among emerging countries. Concentration of the Fund's assets
in one or a few emerging countries and currencies will subject the Fund to
greater risks than if the Fund's assets were not geographically concentrated.

      Investments in Emerging Countries involve certain risks which are not
present in investments in more developed countries. The Fund may purchase
privately placed equity securities, equity securities of 


                                      B-11
<PAGE>
 
companies that are in the process of being privatized by foreign governments,
securities of issuers that have not paid dividends on a timely basis, equity
securities of issuers that have experienced difficulties, and securities of
companies without performance records.

      Other. The Fund may invest in the aggregate up to 35% of its total assets
in (i) fixed-income securities, such as corporate debt and bank obligations, of
private and governmental emerging country issuers; and (ii) equity and
fixed-income securities of issuers in developed countries.

Asia Growth Fund

      Objective. This Fund seeks long-term capital appreciation.

      Primary Investment Focus. This Fund invests, under normal circumstances,
substantially all, and at least 65% of its total assets in equity securities of
Asian issuers. An Asian issuer is any company that either: (i) has a class of
its securities whose principal securities markets is in one of more Asian
countries; (ii) derives 50% or more of its total revenue from goods produced,
sales made or services performed in one or more Asian countries; (iii) maintains
50% or more of its assets in one or more Asian countries; or (iv) is organized
under the laws of, or has a principal office in, an Asian country. Many of the
countries in which the Fund may invest have emerging markets or economies which
involve certain risks which are not present in investments in more developed
countries.

      This Fund may allocate its assets among the Asian countries as determined
from time to time by its investment adviser. For purposes of the Fund's
investment policies, Asian countries are China, Hong Kong, India, Indonesia,
Malaysia, Pakistan, the Philippines, Singapore, South Korea, Sri Lanka, Taiwan
and Thailand as well as any other country in Asia (other than Japan) to the
extent that foreign investors are permitted by applicable law to make such
investments. Allocation of the Fund's investments will depend upon the
investment adviser's view of the relative attractiveness of the Asian markets
and particular issuers. Concentration of the Fund's assets in one or a few of
the Asian countries and Asian currencies will subject the Fund to greater risks
than if the Fund's assets were not geographically concentrated. For example, on
January 31, 1999 (the end of the Fund's last fiscal year), more than 25% of the
Fund's assets were invested in securities traded in Hong Kong.

      Other. The Fund may invest in the aggregate up to 35% of its total assets
in equity securities of issuers in other countries, including Japan, and in
fixed-income securities, such as corporate debt and bank obligations.

Financial Square Prime Obligations Fund

      Objective. This Fund seeks to maximize current income to the extent
consistent with the preservation of capital and the maintenance of liquidity by
investing exclusively in high quality money market instruments.

      Primary Investment Focus. This Fund invests in securities of the U.S.
Government, its agencies, authorities and instrumentalities, obligations of U.S.
banks, commercial paper, and other short-term obligations of U.S. companies,
states, municipalities and other entities and repurchase agreements. Securities
purchased by the Fund will be determined by its investment adviser to present
minimal credit risks, and will have remaining maturities (as determined in
accordance with regulatory requirements) of 13 months or less at the time of
purchase. The dollar-weighted average maturity of the Fund will not exceed 90
days.


                                      B-12
<PAGE>
 
      Other. The investments of this Fund are limited by regulations applicable
to money market funds as described in its Prospectus, and do not include many of
the types of investments that are permitted for the other Underlying
Funds. Although this Fund attempts to maintain a stable net asset value of $1.00
per share, there is no assurance that it will be able to do so on a continuous
basis. Like investments in the other Underlying Funds, an investment in this
Fund is neither insured nor guaranteed by the U.S. Government or any
governmental authority.

Adjustable Rate Government Fund

      Objective. This Fund seeks to provide a high level of current income,
consistent with low volatility of principal.

      Duration. Under normal interest rate conditions, the Fund's duration is
expected to be in a range approximately equal to that of a six-month to one-year
U.S. Treasury security. In addition, under normal interest rate conditions, the
Fund's maximum duration will not exceed two years. The approximate interest rate
sensitivity of the Fund is expected to be comparable to a nine-month U.S.
Treasury bill.

      Investment Sector. This Fund invests, under normal circumstances, at least
65% of its total assets in U.S. Government Securities that are adjustable rate
mortgage pass-through securities and other mortgage securities with periodic
interest rate resets. The remainder of the Fund's assets (up to 35%) may be
invested in other U.S. Government Securities, including fixed rate mortgage
pass-through securities, other securities representing an interest in or
collateralized by adjustable rate and fixed rate mortgage loans
("Mortgage-Backed Securities") and repurchase agreements collateralized by U.S.
Government Securities. Substantially all of the Fund's assets will be invested
in U.S. Government Securities. 100% of the Fund's portfolio will be invested in
U.S. dollar-denominated securities.

      Credit Quality. This Fund invests in U.S. Government Securities and
repurchase agreements collateralized by such securities.

      Other. This Fund may employ certain active management techniques to manage
its duration and term structure and to seek to enhance returns. These techniques
include, but are not limited to, the use of financial futures contracts, option
contracts (including options on futures), mortgage, credit and interest rate
swaps and interest rate floors, caps and collars. The Fund may also employ other
investment techniques to seek to enhance returns, such as lending portfolio
securities and entering into mortgage dollar rolls, repurchase agreements and
other investment practices.

Short Duration Government Fund

      Objective. This Fund seeks a high level of current income and secondarily,
in seeking current income, may also consider the potential for capital
appreciation.

      Duration. Under normal interest rate conditions, the Fund's duration is
expected to be equal to that of the Fund's benchmark, the two-year U.S. Treasury
security, plus or minus .5 years. In addition, under normal interest rate
conditions, the Fund's maximum duration will not exceed three years. The
approximate interest rate sensitivity of the Fund is expected to be comparable
to a two-year U.S. Treasury note.


                                      B-13
<PAGE>
 
      Investment Sector. This Fund invests, under normal market conditions, at
least 65% of its total assets in U.S. Government Securities and in repurchase
agreements collateralized by such securities. Substantially all of the Fund's
assets will be invested in U.S. Government Securities. 100% of the Fund's
portfolio will be invested in U.S. dollar-denominated securities.

      Credit Quality. This Fund invests in U.S. Government Securities and
repurchase agreements collateralized by such securities.

      Other. This Fund may employ certain active management techniques to manage
its duration and term structure and to seek to enhance returns. These techniques
include, but are not limited to, the use of financial futures contracts, option
contracts (including options on futures), mortgage, credit and interest rate
swaps and interest rate floors, caps and collars. The Fund may also employ other
investment techniques to seek to enhance returns, such as lending portfolio
securities and entering into mortgage dollar rolls, repurchase agreements and
other investment practices.

Government Income Fund

      Objective. This Fund seeks a high level of current income, consistent with
safety of principal.

      Duration. Under normal interest rate conditions, the Fund's duration is
expected to be equal to that of the Fund's benchmark, the Lehman Brothers Mutual
Fund Government/Mortgage Index, plus or minus one year. In addition, under
normal interest rate conditions, the Fund's maximum duration will not exceed six
years. The approximate interest rate sensitivity of the Fund is expected to be
comparable to a five-year U.S. Treasury note.

      Investment Sector. This Fund invests, under normal circumstances, at least
65% of its total assets in U.S. Government Securities and in repurchase
agreements collateralized by such securities. The remainder of the Fund's assets
may be invested in non-government securities such as privately issued
Mortgage-Backed Securities, Asset-Backed Securities and corporate securities.
100% of the Fund's portfolio will be invested in U.S. dollar-denominated
securities.

      Credit Quality. This Fund's non-U.S. Government Securities will be rated,
at the time of purchase, AAA or Aaa by a Nationally Recognized Statistical
Rating Organization (an "NRSRO") or, if unrated, will be determined by the
Fund's investment adviser to be of comparable quality.

      Other. This Fund may employ certain active management techniques to manage
its duration and term structure and to seek to enhance returns. These techniques
include, but are not limited to, the use of financial futures contracts, option
contracts (including options on futures), mortgage, credit and interest rate
swaps and interest rate floors, caps and collars. The Fund may also employ other
investment techniques to seek to enhance returns, such as lending portfolio
securities and entering into mortgage dollar rolls, repurchase agreements and
other investment practices.

Core Fixed Income Fund

      Objective. This Fund seeks a total return consisting of capital
appreciation and income that exceeds the total return of the Lehman Brothers
Aggregate Bond Index (the "Index").

      Duration. Under normal interest rate conditions, the Fund's duration is
expected to be equal to that of the Fund's benchmark, the Lehman Brothers
Aggregate Bond Index, plus or minus one year. In addition, 


                                      B-14
<PAGE>
 
under normal interest rate conditions, the Fund's maximum duration will not
exceed six years. The approximate interest rate sensitivity of the Fund is
expected to be comparable to a five-year U.S. Treasury note.

      Investment Sector. This Fund invests, under normal circumstances, at least
65% of its total assets in fixed-income securities, including U.S. Government
Securities, corporate debt securities, Mortgage-Backed Securities, and
Asset-Backed Securities. The Fund's investments in non-dollar denominated
obligations will not exceed 25% of its total assets at the time of investment,
of which 10% may be invested in obligations of issuers in countries with
emerging markets or economies. A number of investment strategies will be used to
achieve the Fund's investment objective, including market sector selection,
determination of yield curve exposure, and issuer selection. In addition, the
Investment Adviser will attempt to take advantage of pricing inefficiencies in
the fixed-income markets.

      The Index currently includes U.S. Government Securities and fixed-rate,
publicly issued, U.S. dollar-denominated fixed-income securities rated at least
BBB or Baa by an NRSRO. Securities rated BBB or Baa are considered medium-grade
obligations with speculative characteristics, and adverse economic conditions or
changing circumstances may weaken their issuers' capability to pay interest and
repay principal. The securities currently included in the Index have at least
one year remaining to maturity; have an outstanding principal amount of at least
$100 million; and are issued by the following types of issuers, with each
category receiving a different weighting in the Index: U.S. Treasury; agencies,
authorities or instrumentalities of the U.S. government; issuers of
Mortgage-Backed Securities; utilities; industrial issuers; financial
institutions; foreign issuers; and issuers of Asset-Backed Securities. In
pursuing its investment objective, the Fund uses the Index as its performance
benchmark, but the Fund will not attempt to replicate the Index. The Fund,
therefore, may invest in securities that are not included in the Index. The
Index is a trademark of Lehman Brothers. Inclusion of a security in the Index
does not imply an opinion by Lehman Brothers as to its attractiveness or
appropriateness for investment. Although Lehman Brothers obtains factual
information used in connection with the Index from sources which it considers
reliable, Lehman Brothers claims no responsibility for the accuracy,
completeness or timeliness of such information and has no liability to any
person for any loss arising from results obtained from the use of the Index
data.

      Credit Quality. All U.S. dollar-denominated fixed-income securities
purchased by the Fund will be rated, at the time of purchase, at least BBB or
Baa by an NRSRO or, if unrated, will be determined by the Fund's investment
adviser to be of comparable quality. The non-U.S. dollar-denominated
fixed-income securities in which the Fund may invest will be rated, at the time
of investment, at least AA or Aa by an NRSRO or, if unrated, will be determined
by the Fund's investment adviser to be of comparable quality.

      Other. This Fund may employ certain active management techniques to manage
its duration and term structure, to seek to hedge its exposure to foreign
currencies and to seek to enhance returns. These techniques include, but are not
limited to, the use of financial futures contracts, option contracts (including
options on futures), forward foreign currency exchange contracts, currency
options and futures, options on foreign currencies, currency, credit, mortgage
and interest rate swaps and interest rate floors, caps and collars. Currency
management techniques involve risks different from those associated with
investing solely in U.S. dollar-denominated fixed-income securities of U.S.
issuers. It is expected that the Fund will use certain currency techniques to
seek to hedge against currency exchange rate fluctuations or to seek to increase
total return. The Fund may invest in custodial receipts, Municipal Securities
and convertible securities. The Fund may also employ other investment techniques
to seek to enhance returns, such as lending portfolio securities and entering
into mortgage dollar rolls, repurchase agreements and other investment
practices.

Global Income Fund

      Objective. This Fund seeks a high total return, emphasizing current
income, and, to a lesser extent, providing opportunities for capital
appreciation.

      Duration. Under normal interest rate conditions, the Fund's duration is
expected to be equal to that of the Fund's benchmark, the J.P. Morgan Global
Government Bond Index (hedged), plus or minus 2.5 years. In addition, under
normal interest rate conditions, the Fund's maximum duration will not exceed 7.5
years. The approximate interest rate sensitivity of the Fund is expected to be
comparable to a six-year government bond.

      Investment Sector. The Fund invests primarily in a portfolio of high
quality fixed-income securities of U.S. and foreign issuers and enters into
transactions in foreign currencies. Under normal market conditions, the Fund
will (i) have at least 30% of its total assets, after considering the effect of
currency positions, denominated in U.S. dollars and (ii) invest in securities of
issuers in at least three countries. The Fund seeks to meet its investment
objective by pursuing investment opportunities in foreign and domestic
fixed-income securities markets and by engaging in currency transactions to seek
to enhance returns and to seek to hedge its portfolio against currency exchange
rate fluctuations.

      The fixed-income securities in which the Fund may invest include: (i) U.S.
Government Securities and custodial receipts therefor; (ii) securities issued or
guaranteed by a foreign government or any of its political subdivisions,
authorities, agencies, instrumentalities or by supranational entities (i.e.,
international organizations designated or supported by governmental entities to
promote economic reconstruction or development, such as the World Bank); (iii)
corporate debt securities; (iv) certificates of deposit and bankers' acceptances
issued or guaranteed by, or time deposits maintained at, U.S. or foreign banks
(and their branches wherever located) having total assets of more than $1
billion; (v) commercial paper; and (vi) Mortgage-Backed and Asset-Backed
Securities.

      Credit Quality. All securities purchased by the Fund will be rated, at the
time of purchase, at least BBB or Baa by an NRSRO. However, the Fund will invest
at least 50% of its total assets in securities rated, at the time of purchase,
AAA or Aaa by an NRSRO. Unrated securities will be determined by the Fund's
investment adviser to be of comparable quality. Securities rated BBB or Baa are
considered medium-grade obligations with speculative characteristics, and
adverse economic conditions or changing circumstances may weaken their issuers'
capacity to pay interest and repay principal.

      Other. This Fund may employ certain active management techniques to manage
its duration and term structure, to seek to hedge its exposure to foreign
currencies and to seek to enhance returns. These techniques include, but are not
limited to, the use of financial futures contracts, option contracts (including
options on futures), forward foreign currency exchange contracts, currency
options and futures, options on foreign currencies, currency, credit, mortgage
and interest rate swaps and interest rate floors, caps and collars. Currency
management techniques involve risks different from those associated with
investing solely in U.S. dollar-denominated fixed-income securities of U.S.
issuers. It is expected that the Fund will use certain currency techniques to
seek to hedge against currency exchange rate fluctuations or to seek to increase
total return. While the Fund will have both long and short currency positions,
its net long and short foreign currency exposure will not exceed the value of
the Fund's total assets. To the extent that the Fund is fully invested in
foreign securities while also maintaining currency positions, it may be exposed
to greater combined risk. The Fund's net currency positions may expose it to
risks independent of its securities positions. The Fund may also employ other
investment techniques to seek to enhance returns, 


                                      B-16
<PAGE>
 
such as lending portfolio securities and entering into mortgage dollar rolls,
repurchase agreements and other investment practices.

      The Fund may invest more than 25% of its total assets in the securities of
corporate and governmental issuers located in each of Canada, Germany, Japan,
and the United Kingdom as well as in the securities of U.S. issuers.
Concentration of the Fund's investments in such issuers will subject the Fund,
to a greater extent than if investment was more limited, to the risks of adverse
securities markets, exchange rates and social, political or economic events
which may occur in those countries. Not more than 25% of the Fund's total assets
will be invested in securities of issuers in any other single foreign country.
The Fund may also invest up to 10% of its total assets in issuers in countries
with emerging markets and economies.

High Yield Fund

      Objective. This Fund seeks a high level of current income and may also
consider the potential for capital appreciation.

      Duration. Under normal interest rate conditions, the Fund's duration is
expected to be equal to that of the Fund's benchmark, the Lehman Brothers High
Yield Bond Index, plus or minus 2.5 years. In addition, under normal interest
rate conditions, the Fund's maximum duration will not exceed 7.5 years. The
approximate interest rate sensitivity of the Fund is expected to be comparable
to a 6-year U.S. Treasury note.

      Investment Sector. This Fund invests, under normal circumstances, at least
65% of its total assets in high yield, fixed-income securities rated, at the
time of investment, below investment grade. Non-investment grade securities are
securities rated BB, Ba or below by an NRSRO, or, if unrated, determined by the
investment adviser to be of comparable quality. The Fund may invest in all types
of fixed-income securities, including senior and subordinated corporate debt
obligations (such as bonds, debentures, notes and commercial paper), convertible
and non-convertible corporate debt obligations, loan participations, custodial
receipts, municipal securities and preferred stock. The Fund may invest up to
25% of its total assets in obligations of domestic and foreign issuers
(including securities of issuers located in countries with emerging markets and
economies) which are denominated in currencies other than the U.S. dollar. Under
normal market conditions, the Fund may invest up to 35% of its total assets in
investment grade fixed-income securities, including U.S. Government Securities.
The Fund may also invest in common stocks, warrants, rights and other equity
securities, but will generally hold such equity investments only when debt or
preferred stock of the issuer of such equity securities is held by the Fund. A
number of investment strategies are used to seek to achieve the Fund's
investment objective, including market sector selection, determination of yield
curve exposure, and issuer selection. In addition, the Fund's investment adviser
will attempt to take advantage of pricing inefficiencies in the fixed-income
markets.

      Credit Quality. This Fund invests at least 65% of its total assets in
securities rated BB or Ba or lower at the time of investment or, if unrated,
determined by the Fund's investment adviser to be of comparable quality. The
Fund may purchase securities of issuers in default. Non-investment grade
securities (commonly known as "junk bonds") tend to offer higher yields than
higher rated securities with similar maturities. Non-investment grade securities
are, however, considered speculative and generally involve greater price
volatility and greater risk of loss of principal and interest than higher rated
securities. See "Description of Investment Securities and Practices." A
description of the corporate bond ratings is contained in Appendix A to this
Additional Statement.

      Other. This Fund may employ certain active management techniques to manage
its duration and term structure, to seek to hedge its exposure to foreign
securities and to seek to enhance returns. These techniques include, but are not
limited to, the use of financial futures contracts, option contracts (including
options on futures), forward foreign currency exchange contracts, currency
options and futures, and currency, credit, mortgage and interest rate swaps.
Currency management techniques involve risks different from those associated
with investing solely in U.S. dollar-denominated fixed-income securities of U.S.
issuers. It is expected that the Fund will use certain currency techniques to
seek to hedge against currency exchange rate fluctuations or to seek to increase
total return. The Fund may also employ other investment techniques to seek to
enhance returns, such as lending portfolio securities and entering into
repurchase agreements and other investment practices.

               DESCRIPTION OF INVESTMENT SECURITIES AND PRACTICES

      The Short-Duration Government and Adjustable Rate Government Funds invest
in U.S. Government Securities and related repurchase agreements, and neither of
these Funds, the Government Income Fund nor the Financial Square Prime
Obligations Fund makes foreign investments. The investments of the Financial
Square Prime Obligations Fund are limited by SEC regulations applicable to money
market funds as described in its prospectus, and do not include many of the
types of investments discussed below that are permitted for the other Underlying
Funds. With these exceptions, and the further exceptions noted below, the
following description applies generally to the Underlying Funds.

      As stated in the Prospectus, the Portfolios may also invest a portion of
their assets in high quality, short-term debt obligations and engage in certain
other investment practices. Further information about the Underlying Funds and
their respective investment objectives and policies is included in their
Prospectus and Additional Statements. There is no assurance that any Portfolio
or Underlying Fund will achieve its objective.

Corporate Debt Obligations

      Each Underlying Fund (other than the Adjustable Rate Government and Short
Duration Government Funds) may, under normal market conditions, invest in
corporate debt obligations, including obligations of industrial, utility and
financial issuers. CORE Large Cap Value Fund, CORE U.S. Equity, CORE Large Cap
Growth, CORE Small Cap Equity and CORE International Equity Funds may only
invest in debt securities that are cash equivalents. Corporate debt obligations
are subject to the risk of an issuer's inability to meet principal and interest
payments on the obligations and may also be subject to price volatility due to
such factors as market interest rates, market perception of the creditworthiness
of the issuer and general market liquidity.

      Fixed-income securities rated BBB or Baa are considered medium-grade
obligations with speculative characteristics, and adverse economic conditions or
changing circumstances may weaken their issuers' capacity to pay interest and
repay principal. Medium to lower rated and comparable non-rated securities tend
to offer higher yields than higher rated securities with the same maturities
because the historical financial condition of the issuers of such securities may
not have been as strong as that of other issuers. Since medium to lower rated
securities generally involve greater risks of loss of income and principal than
higher rated securities, investors should consider carefully the relative risks
associated with investment in securities which carry medium to lower ratings and
in comparable unrated securities. In addition to the risk of default, there are
the related costs of recovery on defaulted issues. The Underlying Funds'
investment advisers will attempt to reduce these risks through portfolio
diversification and by 


                                      B-18
<PAGE>
 
analysis of each issuer and its ability to make timely payments of income and
principal, as well as broad economic trends and corporate developments.

      Trust Preferreds. The Government Income, Core Fixed Income, Global Income
and High Yield Funds may invest in trust preferred securities. A trust preferred
or capital security is a long dated bond (for example 30 years) with preferred
features. The preferred features are that payment of interest can be deferred
for a specified period without initiating a default event. From a bondholder's
viewpoint, the securities are senior in claim to standard preferred but are
junior to other bondholders. From the issuer's viewpoint, the securities are
attractive because their interest is deductible for tax purposes like other
types of debt instruments.

      High Yield Securities. Bonds rated BB or below by Standard & Poor's
Ratings Group ("Standard & Poor's") or Ba or below by Moody's Investors Service,
Inc. ("Moody's") (or comparable rated and unrated securities) are commonly
referred to as "junk bonds" and are considered speculative. The ability of their
issuers to make principal and interest payments may be questionable. In some
cases, such bonds may be highly speculative, have poor prospects for reaching
investment grade standing and be in default. As a result, investment in such
bonds will entail greater risks than those associated with investment grade
bonds (i.e., bonds rated AAA, AA, A or BBB by Standard and Poor's or Aaa, Aa, A
or Baa by Moody's). Analysis of the creditworthiness of issuers of high yield
securities may be more complex than for issuers of higher quality debt
securities, and the ability of an Underlying Fund to achieve its investment
objective may, to the extent of its investments in high yield securities, be
more dependent upon such creditworthiness analysis than would be the case if the
Underlying Fund were investing in higher quality securities. See Appendix A to
this Additional Statement for a description of the corporate bond and preferred
stock ratings by Standard & Poor's, Moody's, Fitch IBCA, Inc. and Duff & Phelps.

      The amount of high yield, fixed-income securities proliferated in the
1980s and early 1990s as a result of increased merger and acquisition and
leveraged buyout activity. Such securities are also issued by less-established
corporations desiring to expand. Risks associated with acquiring the securities
of such issuers generally are greater than is the case with higher rated
securities because such issuers are often less creditworthy companies or are
highly leveraged and generally less able than more established or less leveraged
entities to make scheduled payments of principal and interest.

      The market values of high yield, fixed-income securities tends to reflect
those individual corporate developments to a greater extent than do those of
higher rated securities, which react primarily to fluctuations in the general
level of interest rates. Issuers of such high yield securities are often highly
leveraged, and may not be able to make use of more traditional methods of
financing. Their ability to service debt obligations may be more adversely
affected than issuers of higher rated securities by economic downturns, specific
corporate developments or the issuers' inability to meet specific projected
business forecasts. These non-investment grade securities also tend to be more
sensitive to economic conditions than higher-rated securities. Negative
publicity about the junk bond market and investor perceptions regarding
lower-rated securities, whether or not based on fundamental analysis, may
depress the prices for such securities.

      Since investors generally perceive that there are greater risks associated
with non-investment grade securities of the type in which the Underlying Funds
may invest, the yields and prices of such securities may tend to fluctuate more
than those for higher-rated securities. In the lower quality segments of the
fixed-income securities market, changes in perceptions of issuers'
creditworthiness tend to occur more frequently and in a more pronounced manner
than do changes in higher quality segments of the fixed-income securities
market, resulting in greater yield and price volatility.


                                      B-19
<PAGE>
 
      Another factor which causes fluctuations in the prices of fixed-income
securities is the supply and demand for similarly rated securities. In addition,
the prices of high yield, fixed-income securities fluctuate in response to the
general level of interest rates. Fluctuations in the prices of portfolio
securities subsequent to their acquisition will not affect cash income from such
securities but will be reflected in an Underlying Fund's net asset value.

      The risk of loss from default for the holders of high yield, fixed-income
securities is significantly greater than is the case for holders of other debt
securities because such high yield, fixed-income securities are generally
unsecured and are often subordinated to the rights of other creditors of the
issuers of such securities. Investment by an Underlying Fund in already
defaulted securities poses an additional risk of loss should nonpayment of
principal and interest continue in respect of such securities. Even if such
securities are held to maturity, recovery by an Underlying Fund of its initial
investment and any anticipated income or appreciation is uncertain. In addition,
an Underlying Fund may incur additional expenses to the extent that it is
required to seek recovery relating to the default in the payment of principal or
interest on such securities or otherwise protect its interests. An Underlying
Fund may be required to liquidate other portfolio securities to satisfy the
Underlying Fund's annual distribution obligations in respect of accrued interest
income on securities which are subsequently written off, even though the
Underlying Fund has not received any cash payments of such interest.

      The secondary market for high yield, fixed-income securities is
concentrated in relatively few markets and is dominated by institutional
investors, including mutual funds, insurance companies and other financial
institutions. Accordingly, the secondary market for such securities is not as
liquid as and is more volatile than the secondary market for higher-rated
securities. In addition, the trading volume for high-yield, fixed-income
securities is generally lower than that of higher rated securities and the
secondary market for high yield, fixed-income securities could shrink or
disappear suddenly and without warning as a result of adverse market or economic
conditions independent of any specific adverse changes in the condition of a
particular issuer. Because of the lack of sufficient market liquidity, a Fund
may incur losses because it will be required to effect sale at a disadvantageous
time and then only at a substantial drop in price. Prices realized upon the sale
of such lower rated or unrated securities, under these circumstances, may be
less than the prices used in calculating an Underlying Fund's net asset value. A
less liquid secondary market also may make it more difficult for an Underlying
Fund to obtain precise valuations of the high yield securities in its portfolio.

      Certain proposed and recently enacted federal laws could adversely affect
the secondary market for high yield securities and the financial condition of
issuers of these securities. The form of proposed legislation and the
probability of such legislation being enacted is uncertain.

      Non-investment grade or high-yield, fixed-income securities also present
risks based on payment expectations. High yield, fixed-income securities
frequently contain "call" or buy-back features which permit the issuer to call
or repurchase the security from its holder. If an issuer exercises such a "call
option" and redeems the security, an Underlying Fund may have to replace such
security with a lower-yielding security, resulting in a decreased return for
investors. In addition, if an Underlying Fund experiences net redemptions of its
shares, it may be forced to sell its higher-rated securities, resulting in a
decline in the overall credit quality of the Underlying Fund's portfolio and
increasing the exposure of the Underlying Fund to the risks of high yield
securities.

Credit ratings issued by credit rating agencies are designed to evaluate the
safety of principal and interest payments of rated securities. They do not,
however, evaluate the market value risk of non-


                                      B-20
<PAGE>
 
investment grade securities and, therefore, may not fully reflect the true risks
of an investment. In addition, credit rating agencies may or may not make timely
changes in a rating to reflect changes in the economy or in the conditions of
the issuer that affect the market value of the security. Consequently, credit
ratings are used only as a preliminary indicator of investment quality.
Investments in non-investment grade and comparable unrated obligations will be
more dependent on the credit analysis of an Underlying Fund's investment adviser
than would be the case with investments in investment-grade debt obligations. An
Underlying Fund's investment adviser employs its own credit research and
analysis, which includes a study of existing debt, capital structure, ability to
service debt and to pay dividends, the issuer's sensitivity to economic
conditions, its operating history and the current trend of earnings. The
investment adviser monitors the investments in an Underlying Fund's portfolio
and evaluates whether to dispose of or to retain non-investment grade and
comparable unrated securities whose credit ratings or credit quality may have
changed.

      Because the market for high yield securities is still relatively new and
has not weathered a major economic recession, it is unknown what effects such a
recession might have on such securities. A widespread economic down turn could
result in increased defaults and losses.

      Loan Participations. The High Yield Fund may invest in loan
participations. Such loans must be to issuers in whose obligations the High
Yield Fund may invest. A loan participation is an interest in a loan to a U.S.
or foreign company or other borrower which is administered and sold by a
financial intermediary. In a typical corporate loan syndication, a number of
lenders, usually banks (co-lenders), lend a corporate borrower a specified sum
pursuant to the terms and conditions of a loan agreement. One of the co-lenders
usually agrees to act as the agent bank with respect to the loan.

      Participation interests acquired by the High Yield Fund may take the form
of a direct or co-lending relationship with the corporate borrower, an
assignment of an interest in the loan by a co-lender or another participant, or
a participation in the seller's share of the loan. When the High Yield Fund acts
as co-lender in connection with a participation interest or when the High Yield
Fund acquires certain participation interests, the High Yield Fund will have
direct recourse against the borrower if the borrower fails to pay scheduled
principal and interest. In cases where the High Yield Fund lacks direct
recourse, it will look to the agent bank to enforce appropriate credit remedies
against the borrower. In these cases, the High Yield Fund may be subject to
delays, expenses and risks that are greater than those that would have been
involved if the Underlying Fund had purchased a direct obligation (such as
commercial paper) of such borrower. For example, in the event of the bankruptcy
or insolvency of the corporate borrower, a loan participation may be subject to
certain defenses by the borrower as a result of improper conduct by the agent
bank. Moreover, under the terms of the loan participation, the High Yield Fund
may be regarded as a creditor of the agent bank (rather than of the underlying
corporate borrower), so that the High Yield Fund may also be subject to the risk
that the agent bank may become insolvent. The secondary market, if any, for
these loan participations is limited and any loan participations purchased by
the High Yield Fund will be regarded as illiquid.

      For purposes of certain investment limitations pertaining to
diversification of the High Yield Fund's portfolio investments, the issuer of a
loan participation will be the underlying borrower. However, in cases where the
High Yield Fund does not have recourse directly against the borrower, both the
borrower and each agent bank and co-lender interposed between the High Yield
Fund and the borrower will be deemed issuers of a loan participation.

Obligations of the United States, Its Agencies, Instrumentalities and Sponsored
Enterprises

      Each Underlying Fund may invest in U.S. government securities, which are
obligations issued or guaranteed by the U.S. government and its agencies,
instrumentalities or sponsored enterprises ("U.S. Government Securities"). Some
U.S. Government Securities (such as Treasury bills, notes and bonds, which
differ only in their interest rates, maturities and times of issuance) are
supported by the full faith and credit of the United States of America. Others,
such as obligations issued or guaranteed by U.S. government agencies,
instrumentalities or sponsored enterprises, are supported either by (a) the
right of the issuer to borrow from the Treasury (such as securities of Federal
Home Loan Banks), (b) the discretionary authority of the U.S. government to
purchase the agency's obligations (such as securities of Federal National
Mortgage Association ("Fannie Mae")) or (c) only the credit of the issuer (such
as securities of the Financing Corporation). The U.S. government is under no
legal obligation, in general, to purchase the obligations of its agencies,
instrumentalities or sponsored enterprises. No assurance can be given that the
U.S. government will provide financial support to the U.S. government agencies,
instrumentalities or sponsored enterprises in the future.

      U.S. Government Securities include (to the extent consistent with the
Investment Company Act of 1940, as amended (the "Act")) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, or its agencies, instrumentalities or sponsored
enterprises. U.S. Government Securities also include (to the extent consistent
with the Act) participations in loans made to foreign governments or their
agencies that are guaranteed as to principal and interest by the U.S. government
or its agencies, instrumentalities or sponsored enterprises. The secondary
market for certain of these participations is extremely limited. In the absence
of a suitable secondary market, such participations are regarded as illiquid.
Each Underlying Fund may also purchase U.S. Government Securities in private
placements, subject to the Underlying Fund's limitation on investment in
illiquid securities.

      The Underlying Funds may also invest in separately traded principal and
interest components of securities guaranteed or issued by the U.S. Treasury that
are traded independently under the separate trading of registered interest and
principal of securities program ("STRIPS").

Bank Obligations

      Certain of the Underlying Funds may invest in obligations issued or
guaranteed by U.S. or foreign banks. Bank obligations, including without
limitation, time deposits, bankers' acceptances and certificates of deposit, may
be general obligations of the parent bank or may be limited to the issuing
branch by the terms of the specific obligations or government regulation.

      Banks are subject to extensive governmental regulations which may limit
both the amount and types of loans which may be made and interest rates which
may be charged. In addition, the profitability of the banking industry is
largely dependent upon the availability and cost of funds for the purpose of
financing lending operations under prevailing money market conditions. General
economic conditions as well as exposure to credit losses arising from possible
financial difficulties of borrowers play an important part in the operations of
this industry.

Deferred Interest, Pay-in-Kind and Capital Appreciation Bonds

      Certain of the Underlying Funds expect to invest in deferred interest and
capital appreciation bonds and pay-in-kind ("PIK") securities. Deferred interest
and capital appreciation bonds are debt securities 


                                      B-22
<PAGE>
 
issued or sold at a discount from their face value and which do not entitle the
holder to any periodic payment of interest prior to maturity or a specified
date. The original issue discount varies depending on the time remaining until
maturity or cash payment date, prevailing interest rates, the liquidity of the
security and the perceived credit quality of the issuer. These securities also
may take the form of debt securities that have been stripped of their unmatured
interest coupons, the coupons themselves or receipts or certificates
representing interests in such stripped debt obligations or coupons. The market
prices of deferred interest, capital appreciation bonds and PIK securities
generally are more volatile than the market prices of interest bearing
securities and are likely to respond to a greater degree to changes in interest
rates than interest bearing securities having similar maturities and credit
quality.

      PIK securities may be debt obligations or preferred shares that provide
the issuer with the option of paying interest or dividends on such obligations
in cash or in the form of additional securities rather than cash. Similar to
zero coupon bonds and deferred interest bonds, PIK securities are designed to
give an issuer flexibility in managing cash flow. PIK securities that are debt
securities can either be senior or subordinated debt and generally trade flat
(i.e., without accrued interest). The trading price of PIK debt securities
generally reflects the market value of the underlying debt plus an amount
representing accrued interest since the last interest payment.

      Deferred interest, capital appreciation and PIK securities involve the
additional risk that, unlike securities that periodically pay interest to
maturity, an Underlying Fund will realize no cash until a specified future
payment date unless a portion of such securities is sold and, if the issuer of
such securities defaults, an Underlying Fund may obtain no return at all on its
investment. In addition, even though such securities do not provide for the
payment of current interest in cash, the Underlying Funds are nonetheless
required to accrue income on such investments for each taxable year and
generally are required to distribute such accrued amounts (net of deductible
expenses, if any) to avoid being subject to tax. Because no cash is generally
received at the time of the accrual, an Underlying Fund may be required to
liquidate other portfolio securities to obtain sufficient cash to satisfy
federal tax distribution requirements applicable to the Underlying Fund.

Zero Coupon Bonds

      An Underlying Fund's investments in fixed-income securities may include
zero coupon bonds, which are debt obligations issued or purchased at a
significant discount from face value. The discount approximates the total amount
of interest the bonds would have accrued and compounded over the period until
maturity. Zero coupon bonds do not require the periodic payment of interest.
Such investments benefit the issuer by mitigating its need for cash to meet debt
service but also require a higher rate of return to attract investors who are
willing to defer receipt of such cash. Such investments may experience greater
volatility in market value than debt obligations which provide for regular
payments of interest. In addition, if an issuer of zero coupon bonds held by an
Underlying Fund defaults, the Underlying Fund may obtain no return at all on its
investment. Each Fund will accrue income on such investments for each taxable
year which (net of deductible expenses, if any) is distributable to shareholders
and which, because no cash is generally received at the time of accrual, may
require the liquidation of other portfolio securities to obtain sufficient cash
to satisfy the Underlying Fund's distribution obligations.

Variable and Floating Rate Securities

      The interest rates payable on certain fixed-income securities in which an
Underlying Fund may invest are not fixed and may fluctuate based upon changes in
market rates. A variable rate obligation has an interest rate which is adjusted
at predesignated periods in response to changes in the market rate of 


                                      B-23
<PAGE>
 
interest on which the interest rate is based. Variable and floating rate
obligations are less effective than fixed rate instruments at locking in a
particular yield. Nevertheless, such obligations may fluctuate in value in
response to interest rate changes if there is a delay between changes in market
interest rates and the interest reset date for the obligation.

      Permissible investments for the Underlying Funds include "leveraged"
inverse floating rate debt instruments ("inverse floaters"), including
"leveraged inverse floaters." The interest rate on inverse floaters resets in
the opposite direction from the market rate of interest to which the inverse
floater is indexed. An inverse floater may be considered to be leveraged to the
extent that its interest rate varies by a magnitude that exceeds the magnitude
of the change in the index rate of interest. The higher the degree of leverage
of an inverse floater, the greater the volatility of its market value.
Accordingly, the duration of an inverse floater may exceed its stated final
maturity. Certain inverse floaters may be deemed to be illiquid securities for
purposes of each Fund's limitation on illiquid investments.

Custodial Receipts

      Each Underlying Fund may invest in custodial receipts in respect of
securities issued or guaranteed as to principal and interest by the U.S.
Government, its agencies, instrumentalities, political subdivisions or
authorities. Such custodial receipts evidence ownership of future interest
payments, principal payments or both on certain notes or bonds issued by the
U.S. Government, its agencies, instrumentalities, political subdivisions or
authorities. These custodial receipts are known by various names, including
"Treasury Receipts," "Treasury Investors Growth Receipts" ("TIGRs"), and
"Certificates of Accrual on Treasury Securities" ("CATs"). For certain
securities law purposes, custodial receipts are not considered U.S. Government
securities.

Municipal Securities

      Certain of the Underlying Funds may invest in bonds, notes and other
instruments issued by or on behalf of states, territories and possessions of the
United States (including the District of Columbia) and their political
subdivisions, agencies or instrumentalities ("Municipal Securities").

      Municipal Securities are often issued to obtain funds for various public
purposes including refunding outstanding obligations, obtaining funds for
general operating expenses, and obtaining funds to lend to other public
institutions and facilities. Municipal Securities also include certain "private
activity bonds" or industrial development bonds, which are issued by or on
behalf of public authorities to provide financing aid to acquire sites or
construct or equip facilities within a municipality for privately or publicly
owned corporations.

      The two principal classifications of Municipal Securities are "general
obligations" and "revenue obligations." General obligations are secured by the
issuer's pledge of its full faith and credit for the payment of principal and
interest, although the characteristics and enforcement of general obligations
may vary according to the law applicable to the particular issuer. Revenue
obligations, which include, but are not limited to, private activity bonds,
resource recovery bonds, certificates of participation and certain municipal
notes, are not backed by the credit and taxing authority of the issuer, and are
payable solely from the revenues derived from a particular facility or class of
facilities or, in some cases, from the proceeds of a special excise or other
specific revenue source. Nevertheless, the obligations of the issuer of a
revenue obligation may be backed by a letter of credit, guarantee or insurance.
General obligations and revenue obligations may be issued in a variety of forms,
including commercial paper, fixed, variable and floating


                                      B-24
<PAGE>
 
rate securities, tender option bonds, auction rate bonds and zero coupon bonds,
deferred interest bonds and capital appreciation bonds.

      In addition to general obligations and revenue obligations, there is a
variety of hybrid and special types of Municipal Securities. There are also
numerous differences in the security of Municipal Securities both within and
between these two principal classifications.

      An entire issue of Municipal Securities may be purchased by one or a small
number of institutional investors such as the High Yield and Core Fixed Income
Funds. Thus, the issue may not be said to be publicly offered. Unlike some
securities that are not publicly offered, a secondary market exists for many
Municipal Securities that were not publicly offered initially and such
securities may be readily marketable.

      The obligations of the issuer to pay the principal of and interest on a
Municipal Security are subject to the provisions of bankruptcy, insolvency and
other laws affecting the rights and remedies of creditors, such as the Federal
Bankruptcy Act, and laws, if any, that may be enacted by Congress or state
legislatures extending the time for payment of principal or interest or imposing
other constraints upon the enforcement of such obligations. There is also the
possibility that, as a result of litigation or other conditions, the power or
ability of the issuer to pay when due principal of or interest on a Municipal
Security may be materially affected.

      Municipal Leases, Certificates of Participation and Other Participation
Interests. Municipal Securities include leases, certificates of participation
and other participation interests. A municipal lease is an obligation in the
form of a lease or installment purchase which is issued by a state or local
government to acquire equipment and facilities. Income from such obligations is
generally exempt from state and local taxes in the state of issuance. Municipal
leases frequently involve special risks not normally associated with general
obligations or revenue bonds. 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 relieve the governmental issuer of
any 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, such leases or contracts may be subject to
the temporary abatement of payments in the event the issuer is prevented from
maintaining occupancy of the leased premises or utilizing the leased equipment.
Although the obligations may be secured by the leased equipment or facilities,
the disposition of the property in the event of non-appropriation or foreclosure
might prove difficult, time consuming and costly, and result in a delay in
recovering or the failure to fully recover an Underlying Fund's original
investment.

      Certificates of participation represent undivided interests in municipal
leases, installment purchase agreements or other instruments. The certificates
are typically issued by a trust or other entity which has received an assignment
of the payments to be made by the state or political subdivision under such
leases or installment purchase agreements.

      Certain municipal lease obligations and certificates of participation may
be deemed to be illiquid for the purpose of an Underlying Fund's limitation on
investments in illiquid securities. Other municipal lease obligations and
certificates of participation acquired by an Underlying Fund may be determined
by its investment adviser, pursuant to guidelines adopted by the Trustees of the
Trust, to be liquid securities for the purpose of such limitation. In
determining the liquidity of municipal lease obligations and certificates of


                                      B-25
<PAGE>
 
participation, the investment adviser will consider a variety of factors
including: (1) the willingness of dealers to bid for the security; (2) the
number of dealers willing to purchase or sell the obligation and the number of
other potential buyers; (3) the frequency of trades or quotes for the
obligation; and (4) the nature of the marketplace trades. In addition, the
investment adviser will consider factors unique to particular lease obligations
and certificates of participation affecting the marketability thereof. These
include the general creditworthiness of the issuer, the importance to the issuer
of the property covered by the lease and the likelihood that the marketability
of the obligation will be maintained throughout the time the obligation is held
by an Underlying Fund.

      The Underlying Funds may purchase participations in Municipal Securities
held by a commercial bank or other financial institution. Such participations
provide an Underlying Fund with the right to a pro rata undivided interest in
the underlying Municipal Securities. In addition, such participations generally
provide an Underlying Fund with the right to demand payment, on not more than
seven days' notice, of all or any part of such Fund's participation interest in
the underlying Municipal Security, plus accrued interest. An Underlying Fund
will only invest in such participations if, in the opinion of bond counsel,
counsel for the issuers of such participations or counsel selected by the
investment advisors, the interest from such participation is exempt from regular
federal income tax.

      Auction Rate Securities. Municipal Securities also include auction rate
Municipal Securities and auction rate preferred securities issued by closed-end
investment companies that invest primarily in Municipal Securities
(collectively, "auction rate securities"). Provided that the auction mechanism
is successful, auction rate securities usually permit the holder to sell the
securities in an auction at par value at specified intervals. The dividend is
reset by "Dutch" auction in which bids are made by broker-dealers and other
institutions for a certain amount of securities at a specified minimum yield.
The dividend rate set by the auction is the lowest interest or dividend rate
that covers all securities offered for sale. While this process is designed to
permit auction rate securities to be traded at par value, there is some risk
that an auction will fail due to insufficient demand for the securities.

      An Underlying Fund's investments in auction rate securities of closed-end
funds are subject to the limitations prescribed by the Act. An Underlying Fund
will indirectly bear its proportionate share of any management and other fees
paid by such closed-end funds in addition to the advisory fees payable directly
by the Underlying Funds.

      Other Types of Municipal Securities. Other types of Municipal Securities
in which certain of the Underlying Funds may invest include municipal notes,
tax-exempt commercial paper, pre-refunded municipal bonds, industrial
development bonds and insured municipal obligations.

      Call Risk and Reinvestment Risk. Municipal Securities may include "call"
provisions which permit the issuers of such securities, at any time or after a
specified period, to redeem the securities prior to their stated maturity. In
the event that Municipal Securities held in an Underlying Fund's portfolio are
called prior to the maturity, the Underlying Fund will be required to reinvest
the proceeds on such securities at an earlier date and may be able to do so only
at lower yields, thereby reducing the Underlying Fund's return on its portfolio
securities.

Mortgage Loans and Mortgage-Backed Securities

      General Characteristics. Certain of the Underlying Funds may invest in
Mortgage-Backed Securities as described in the Prospectus. Each mortgage pool
underlying Mortgage-Backed Securities consists of mortgage loans evidenced by
promissory notes secured by first mortgages or first deeds of trust


                                      B-26
<PAGE>
 
or other similar security instruments creating a first lien on owner occupied
and non-owner occupied one-unit to four-unit residential properties, multifamily
(i.e., five or more) properties, agriculture properties, commercial properties
and mixed use properties (the "Mortgaged Properties"). The Mortgaged Properties
may consist of detached individual dwelling units, multifamily dwelling units,
individual condominiums, townhouses, duplexes, triplexes, fourplexes, row
houses, individual units in planned unit developments and other attached
dwelling units. The Mortgaged Properties may also include residential investment
properties and second homes.

      The investment characteristics of adjustable and fixed rate
Mortgage-Backed Securities differ from those of traditional fixed-income
securities. The major differences include the payment of interest and principal
on Mortgage-Backed Securities on a more frequent (usually monthly) schedule, and
the possibility that principal may be prepaid at any time due to prepayments on
the underlying mortgage loans or other assets. These differences can result in
significantly greater price and yield volatility than is the case with
traditional fixed-income securities. As a result, if an Underlying Fund
purchases Mortgage-Backed Securities at a premium, a faster than expected
prepayment rate will reduce both the market value and the yield to maturity from
those which were anticipated. A prepayment rate that is slower than expected
will have the opposite effect of increasing yield to maturity and market value.
Conversely, if an Underlying Fund purchases Mortgage-Backed Securities at a
discount, faster than expected prepayments will increase, while slower than
expected prepayments will reduce yield to maturity and market values. To the
extent that an Underlying Fund invests in Mortgage-Backed Securities, its
investment adviser may seek to manage these potential risks by investing in a
variety of Mortgage-Backed Securities and by using certain hedging techniques.

      Adjustable Rate Mortgage Loans ("ARMs"). ARMs generally provide for a
fixed initial mortgage interest rate for a specified period of time. Thereafter,
the interest rates (the "Mortgage Interest Rates") may be subject to periodic
adjustment based on changes in the applicable index rate (the "Index Rate"). The
adjusted rate would be equal to the Index Rate plus a fixed percentage spread
over the Index Rate established for each ARM at the time of its origination.
ARMs allow a Fund to participate in increases in interest rates through periodic
increases in the securities coupon rates. During periods of declining interest
rates, coupon rates may readjust downward resulting in lower yields to a Fund.

      Adjustable interest rates can cause payment increases that some mortgagors
may find difficult to make. However, certain ARMs may provide that the Mortgage
Interest Rate may not be adjusted to a rate above an applicable lifetime maximum
rate or below an applicable lifetime minimum rate for such ARM. Certain ARMs may
also be subject to limitations on the maximum amount by which the Mortgage
Interest Rate may adjust for any single adjustment period (the "Maximum
Adjustment"). Other ARMs ("Negatively Amortizing ARMs") may provide instead or
as well for limitations on changes in the monthly payment on such ARMs.
Limitations on monthly payments can result in monthly payments which are greater
or less than the amount necessary to amortize a Negatively Amortizing ARM by its
maturity at the Mortgage Interest Rate in effect in any particular month. In the
event that a monthly payment is not sufficient to pay the interest accruing on a
Negatively Amortizing ARM, any such excess interest is added to the principal
balance of the loan, causing negative amortization, and will be repaid through
future monthly payments. It may take borrowers under Negatively Amortizing ARMs
longer periods of time to build up equity and may increase the likelihood of
default by such borrowers. In the event that a monthly payment exceeds the sum
of the interest accrued at the applicable Mortgage Interest Rate and the
principal payment which would have been necessary to amortize the outstanding
principal balance over the remaining term of the loan, the excess (or
"accelerated amortization") further reduces the principal balance of the ARM.
Negatively Amortizing ARMs do not provide for the extension of their original
maturity to accommodate changes in their Mortgage Interest Rate. As a result,
unless there is a periodic recalculation


                                      B-27
<PAGE>
 
of the payment amount (which there generally is), the final payment may be
substantially larger than the other payments. These limitations on periodic
increases in interest rates and on changes in monthly payments protect borrowers
from unlimited interest rate and payment increases.

      ARMs also have the risk of prepayments. The rate of principal prepayments
with respect to ARMs has fluctuated in recent years. As with fixed-rate mortgage
loans, ARMs may be subject to a greater rate of principal repayments in a
declining interest rate environment resulting in lower yields to a Fund. For
example, if prevailing interest rates fall significantly, ARMs could be subject
to higher prepayment rates (than if prevailing interest rates remain constant or
increase) because the availability of low fixed-rate mortgages may encourage
mortgagors to refinance their ARMs to "lock-in" a fixed-rate mortgage.
Conversely, if prevailing interest rates rise significantly, ARMs may prepay
more slowly. As with fixed-rate mortgages, ARM prepayment rates vary in both
stable and changing interest rate environments.

      There are two main categories of indices which provide the basis for rate
adjustments on ARMs: those based on U.S. Treasury securities and those derived
from a calculated measure, such as a cost of funds index or a moving average of
mortgage rates. Commonly utilized indices include the one-year, three-year and
five-year constant maturity Treasury rates, the three-month Treasury bill rate,
the 180-day Treasury bill rate, rates on longer-term Treasury securities, the
11th District Federal Home Loan Bank Cost of Funds, the National Median Cost of
Funds, the one-month, three-month, six-month or one-year London Interbank
Offered Rate, the prime rate of a specific bank or commercial paper rates. Some
indices, such as the one-year constant maturity Treasury rate, closely mirror
changes in market interest rate levels. Others, such as the 11th District
Federal Home Loan Bank Cost of Funds index, tend to lag behind changes in market
rate levels and tend to be somewhat less volatile. The degree of volatility in
the market value of an Underlying Fund's portfolio and, therefore, in the net
asset value of an Underlying Fund's shares will be a function of the length of
the interest rate reset periods and the degree of volatility in the applicable
indices.

      Fixed-Rate Mortgage Loans. Generally, fixed-rate mortgage loans included
in a mortgage pool (the "Fixed-Rate Mortgage Loans") will bear simple interest
at fixed annual rates and have original terms to maturity ranging from 5 to 40
years. Fixed-Rate Mortgage Loans generally provide for monthly payments of
principal and interest in substantially equal installments for the term of the
mortgage note in sufficient amounts to fully amortize principal by maturity,
although certain Fixed-Rate Mortgage Loans provide for a large final "balloon"
payment upon maturity.

      Legal Considerations of Mortgage Loans. The following is a discussion of
certain legal and regulatory aspects of the mortgage loans. These regulations
may impair the ability of a mortgage lender to enforce its rights under the
mortgage documents. These regulations may adversely affect the Underlying Funds'
investments in Mortgage-Backed Securities (including those issued or guaranteed
by the U.S. government, its agencies or instrumentalities) by delaying the
Underlying Funds' receipt of payments derived from principal or interest on
mortgage loans affected by such regulations.

1.    Foreclosure. A foreclosure of a defaulted mortgage loan may be delayed due
      to compliance with statutory notice or service of process provisions,
      difficulties in locating necessary parties or legal challenges to the
      mortgagee's right to foreclose. Depending upon market conditions, the
      ultimate proceeds of the sale of foreclosed property may not equal the
      amounts owed on the Mortgage-Backed Securities.

      Furthermore, courts in some cases have imposed general equitable
      principles upon foreclosure generally designed to relieve the borrower
      from the legal effect of default and have required lenders 


                                      B-28
<PAGE>
 
      to undertake affirmative and expensive actions to determine the causes for
      the default and the likelihood of loan reinstatement.

2.    Rights of Redemption. In some states, after foreclosure of a mortgage
      loan, the borrower and foreclosed junior lienors are given a statutory
      period in which to redeem the property, which right may diminish the
      mortgagee's ability to sell the property.

3.    Legislative Limitations. In addition to anti-deficiency and related
      legislation, numerous other federal and state statutory provisions,
      including the federal bankruptcy laws and state laws affording relief to
      debtors, may interfere with or affect the ability of a secured mortgage
      lender to enforce its security interest. For example, a bankruptcy court
      may grant the debtor a reasonable time to cure a default on a mortgage
      loan, including a payment default. The court in certain instances may also
      reduce the monthly payments due under such mortgage loan, change the rate
      of interest, reduce the principal balance of the loan to the then-current
      appraised value of the related mortgaged property, alter the mortgage loan
      repayment schedule and grant priority of certain liens over the lien of
      the mortgage loan. If a court relieves a borrower's obligation to repay
      amounts otherwise due on a mortgage loan, the mortgage loan servicer will
      not be required to advance such amounts, and any loss may be borne by the
      holders of securities backed by such loans. In addition, numerous federal
      and state consumer protection laws impose penalties for failure to comply
      with specific requirements in connection with origination and servicing of
      mortgage loans.

4.    "Due-on-Sale" Provisions. Fixed-rate mortgage loans may contain a
      so-called "due-on-sale" clause permitting acceleration of the maturity of
      the mortgage loan if the borrower transfers the property. The Garn-St.
      Germain Depository Institutions Act of 1982 sets forth nine specific
      instances in which no mortgage lender covered by that Act may exercise a
      "due-on-sale" clause upon a transfer of property. The inability to enforce
      a "due-on-sale" clause or the lack of such a clause in mortgage loan
      documents may result in a mortgage loan being assumed by a purchaser of
      the property that bears an interest rate below the current market rate.

5.    Usury Laws. Some states prohibit charging interest on mortgage loans in
      excess of statutory limits. If such limits are exceeded, substantial
      penalties may be incurred and, in some cases, enforceability of the
      obligation to pay principal and interest may be affected.

      Government Guaranteed Mortgage-Backed Securities. There are several types
of guaranteed Mortgage-Backed Securities currently available, including
guaranteed mortgage pass-through certificates and multiple class securities,
which include guaranteed Real Estate Mortgage Investment Conduit Certificates
("REMIC Certificates"), collateralized mortgage obligations and stripped
Mortgage-Backed Securities. An Underlying Fund is permitted to invest in other
types of Mortgage-Backed Securities that may be available in the future to the
extent consistent with its investment policies and objective.

      An Underlying Fund's investments in Mortgage-Backed Securities may include
securities issued or guaranteed by the U.S. Government or one of its agencies,
authorities, instrumentalities or sponsored enterprises, such as the Government
National Mortgage Association ("Ginnie Mae"), the Federal National Mortgage
Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation
("Freddie Mac").

      Ginnie Mae Certificates. Ginnie Mae is a wholly-owned corporate
instrumentality of the United States. Ginnie Mae is authorized to guarantee the
timely payment of the principal of and interest on certificates that are based
on and backed by a pool of mortgage loans insured by the Federal Housing
Administration ("FHA Loans"), or guaranteed by the Veterans Administration ("VA
Loans"), or by pools 


                                      B-29
<PAGE>
 
of other eligible mortgage loans. In order to meet its obligations under any
guaranty, Ginnie Mae is authorized to borrow from the United States Treasury in
an unlimited amount.

      Fannie Mae Certificates. Fannie Mae is a stockholder-owned corporation
chartered under an act of the United States Congress. Each Fannie Mae
Certificate is issued and guaranteed by Fannie Mae and represents an undivided
interest in a pool of mortgage loans (a "Pool") formed by Fannie Mae. Each Pool
consists of residential mortgage loans ("Mortgage Loans") either previously
owned by Fannie Mae or purchased by it in connection with the formation of the
Pool. The Mortgage Loans may be either conventional Mortgage Loans (i.e., not
insured or guaranteed by any U.S. Government agency) or Mortgage Loans that are
either insured by the FHA or guaranteed by the Veterans Administration ("VA").
However, the Mortgage Loans in Fannie Mae Pools are primarily conventional
Mortgage Loans. The lenders originating and servicing the Mortgage Loans are
subject to certain eligibility requirements established by Fannie Mae.

      Fannie Mae has certain contractual responsibilities. With respect to each
Pool, Fannie Mae is obligated to distribute scheduled monthly installments of
principal and interest after Fannie Mae's servicing and guaranty fee, whether or
not received, to Certificate holders. Fannie Mae also is obligated to distribute
to holders of Certificates an amount equal to the full principal balance of any
foreclosed Mortgage Loan, whether or not such principal balance is actually
recovered. The obligations of Fannie Mae under its guaranty of the Fannie Mae
Certificates are obligations solely of Fannie Mae.

      Freddie Mac Certificates. Freddie Mac is a publicly held U.S. Government
sponsored enterprise. The principal activity of Freddie Mac currently is the
purchase of first lien, conventional, residential mortgage loans and
participation interests in such mortgage loans and their resale in the form of
mortgage securities, primarily Freddie Mac Certificates. A Freddie Mac
Certificate represents a pro rata interest in a group of mortgage loans or
participation in mortgage loans (a "Freddie Mac Certificate group") purchased by
Freddie Mac.

      Freddie Mac guarantees to each registered holder of a Freddie Mac
Certificate the timely payment of interest at the rate provided for by such
Freddie Mac Certificate (whether or not received on the underlying loans).
Freddie Mac also guarantees to each registered Certificate holder ultimate
collection of all principal of the related mortgage loans, without any offset or
deduction, but does not, generally, guarantee the timely payment of scheduled
principal. The obligations of Freddie Mac under its guaranty of Freddie Mac
Certificates are obligations solely of Freddie Mac.

      The mortgage loans underlying the Freddie Mac and Fannie Mae Certificates
consist of adjustable rate or fixed rate mortgage loans with original terms to
maturity of between five and thirty years. Substantially all of these mortgage
loans are secured by first liens on one-to-four-family residential properties or
multifamily projects. Each mortgage loan must meet the applicable standards set
forth in the law creating Freddie Mac or Fannie Mae. A Freddie Mac Certificate
group may include whole loans, participation interests in whole loans, undivided
interests in whole loans and participations comprising another Freddie Mac
Certificate group.

      Conventional Mortgage Loans. The conventional mortgage loans underlying
the Freddie Mac and Fannie Mae Certificates consist of adjustable rate or
fixed-rate mortgage loans with original terms to maturity of between five and
thirty years. Substantially all of these mortgage loans are secured by first
liens on one- to four-family residential properties or multi-family projects.
Each mortgage loan must meet the applicable standards set forth in the law
creating Freddie Mac or Fannie Mae. A Freddie Mac 


                                      B-30
<PAGE>
 
Certificate group may include whole loans, participation interests in whole
loans, undivided interests in whole loans and participations comprising another
Freddie Mac Certificate group.

      Mortgage Pass-Through Securities. As described in the Prospectus, the
Underlying Funds may invest in both government guaranteed and privately issued
mortgage pass-through securities ("Mortgage Pass-Throughs"); that is, fixed or
adjustable rate Mortgage-Backed Securities which provide for monthly payments
that are a "pass-through" of the monthly interest and principal payments
(including any prepayments) made by the individual borrowers on the pooled
mortgage loans, net of any fees or other amounts paid to any guarantor,
administrator and/or servicer of the underlying mortgage loans.

      The following discussion describes only a few of the wide variety of
structures of Mortgage Pass-Throughs that are available or may be issued.

      Description of Certificates. Mortgage Pass-Throughs may be issued in one
or more classes of senior certificates and one or more classes of subordinate
certificates. Each such class may bear a different pass-through rate. Generally,
each certificate will evidence the specified interest of the holder thereof in
the payments of principal or interest or both in respect of the mortgage pool
comprising part of the trust fund for such certificates.

      Any class of certificates may also be divided into subclasses entitled to
varying amounts of principal and interest. If a REMIC election has been made,
certificates of such subclasses may be entitled to payments on the basis of a
stated principal balance and stated interest rate, and payments among different
subclasses may be made on a sequential, concurrent, pro rata or disproportionate
basis, or any combination thereof. The stated interest rate on any such subclass
of certificates may be a fixed rate or one which varies in direct or inverse
relationship to an objective interest index.

      Generally, each registered holder of a certificate will be entitled to
receive its pro rata share of monthly distributions of all or a portion of
principal of the underlying mortgage loans or of interest on the principal
balances thereof, which accrues at the applicable mortgage pass-through rate, or
both. The difference between the mortgage interest rate and the related mortgage
pass-through rate (less the amount, if any, of retained yield) with respect to
each mortgage loan will generally be paid to the servicer as a servicing fee.
Since certain adjustable rate mortgage loans included in a mortgage pool may
provide for deferred interest (i.e., negative amortization), the amount of
interest actually paid by a mortgagor in any month may be less than the amount
of interest accrued on the outstanding principal balance of the related mortgage
loan during the relevant period at the applicable mortgage interest rate. In
such event, the amount of interest that is treated as deferred interest will be
added to the principal balance of the related mortgage loan and will be
distributed pro rata to certificate-holders as principal of such mortgage loan
when paid by the mortgagor in subsequent monthly payments or at maturity.

      Ratings. The ratings assigned by a rating organization to Mortgage
Pass-Throughs address the likelihood of the receipt of all distributions on the
underlying mortgage loans by the related certificate-holders under the
agreements pursuant to which such certificates are issued. A rating
organization's ratings take into consideration the credit quality of the related
mortgage pool, including any credit support providers, structural and legal
aspects associated with such certificates, and the extent to which the payment
stream on such mortgage pool is adequate to make payments required by such
certificates. A rating organization's ratings on such certificates do not,
however, constitute a statement regarding frequency of prepayments on the
related mortgage loans. In addition, the rating assigned by a rating
organization to a certificate does not address the remote possibility that, in
the event of the insolvency of the issuer of certificates where a subordinated
interest was retained, the issuance and sale of the senior certificates may 


                                      B-31
<PAGE>
 
be recharacterized as a financing and, as a result of such recharacterization,
payments on such certificates may be affected.

      Credit Enhancement. Credit support falls generally into two categories:
(i) liquidity protection and (ii) protection against losses resulting from
default by an obligor on the underlying assets. Liquidity protection refers to
the provision of advances, generally by the entity administering the pools of
mortgages, the provision of a reserve fund, or a combination thereof, to ensure,
subject to certain limitations, that scheduled payments on the underlying pool
are made in a timely fashion. Protection against losses resulting from default
ensures ultimate payment of the obligations on at least a portion of the assets
in the pool. Such credit support can be provided by, among other things, payment
guarantees, letters of credit, pool insurance, subordination, or any combination
thereof.

      Subordination; Shifting of Interest; Reserve Fund. In order to achieve
ratings on one or more classes of Mortgage Pass-Throughs, one or more classes of
certificates may be subordinate certificates which provide that the rights of
the subordinate certificate-holders to receive any or a specified portion of
distributions with respect to the underlying mortgage loans may be subordinated
to the rights of the senior certificate-holders. If so structured, the
subordination feature may be enhanced by distributing to the senior
certificate-holders on certain distribution dates, as payment of principal, a
specified percentage (which generally declines over time) of all principal
payments received during the preceding prepayment period ("shifting interest
credit enhancement"). This will have the effect of accelerating the amortization
of the senior certificates while increasing the interest in the trust fund
evidenced by the subordinate certificates. Increasing the interest of the
subordinate certificates relative to that of the senior certificates is intended
to preserve the availability of the subordination provided by the subordinate
certificates. In addition, because the senior certificate-holders in a shifting
interest credit enhancement structure are entitled to receive a percentage of
principal prepayments which is greater than their proportionate interest in the
trust fund, the rate of principal prepayments on the mortgage loans will have an
even greater effect on the rate of principal payments and the amount of interest
payments on, and the yield to maturity of, the senior certificates.

      In addition to providing for a preferential right of the senior
certificate-holders to receive current distributions from the mortgage pool, a
reserve fund may be established relating to such certificates (the "Reserve
Fund"). The Reserve Fund may be created with an initial cash deposit by the
originator or servicer and augmented by the retention of distributions otherwise
available to the subordinate certificate-holders or by excess servicing fees
until the Reserve Fund reaches a specified amount.

      The subordination feature, and any Reserve Fund, are intended to enhance
the likelihood of timely receipt by senior certificate-holders of the full
amount of scheduled monthly payments of principal and interest due them and will
protect the senior certificate-holders against certain losses; however, in
certain circumstances the Reserve Fund could be depleted and temporary
shortfalls could result. In the event the Reserve Fund is depleted before the
subordinated amount is reduced to zero, senior certificate-holders will
nevertheless have a preferential right to receive current distributions from the
mortgage pool to the extent of the then outstanding subordinated amount. Unless
otherwise specified, until the subordinated amount is reduced to zero, on any
distribution date any amount otherwise distributable to the subordinate
certificates or, to the extent specified, in the Reserve Fund will generally be
used to offset the amount of any losses realized with respect to the mortgage
loans ("Realized Losses"). Realized Losses remaining after application of such
amounts will generally be applied to reduce the ownership interest of the
subordinate certificates in the mortgage pool. If the subordinated amount has
been reduced to zero, Realized Losses generally will be allocated pro rata among
all certificate-holders in proportion to their respective outstanding interests
in the mortgage pool.


                                      B-32
<PAGE>
 
      Alternative Credit Enhancement. As an alternative, or in addition to the
credit enhancement afforded by subordination, credit enhancement for Mortgage
Pass-Throughs may be provided by mortgage insurance, hazard insurance, by the
deposit of cash, certificates of deposit, letters of credit, a limited guaranty
or by such other methods as are acceptable to a rating agency. In certain
circumstances, such as where credit enhancement is provided by guarantees or a
letter of credit, the security is subject to credit risk because of its exposure
to an external credit enhancement provider.

      Voluntary Advances. Generally, in the event of delinquencies in payments
on the mortgage loans underlying the Mortgage Pass-Throughs, the servicer agrees
to make advances of cash for the benefit of certificate-holders, but only to the
extent that it determines such voluntary advances will be recoverable from
future payments and collections on the mortgage loans or otherwise.

      Optional Termination. Generally, the servicer may, at its option with
respect to any certificates, repurchase all of the underlying mortgage loans
remaining outstanding at such time as the aggregate outstanding principal
balance of such mortgage loans is less than a specified percentage (generally
5-10%) of the aggregate outstanding principal balance of the mortgage loans as
of the cut-off date specified with respect to such series.

      Multiple Class Mortgage-Backed Securities and Collateralized Mortgage
Obligations. An Underlying Fund may invest in multiple class securities
including collateralized mortgage obligations ("CMOs") and REMIC Certificates.
These securities may be issued by U.S. Government agencies and instrumentalities
such as Fannie Mae or Freddie Mac or by trusts formed by private originators of,
or investors in, mortgage loans, including savings and loan associations,
mortgage bankers, commercial banks, insurance companies, investment banks and
special purpose subsidiaries of the foregoing. In general, CMOs are debt
obligations of a legal entity that are collateralized by, and multiple class
Mortgage-Backed Securities represent direct ownership interests in, a pool of
mortgage loans or Mortgage-Backed Securities the payments on which are used to
make payments on the CMOs or multiple class Mortgage-Backed Securities.

      Fannie Mae REMIC Certificates are issued and guaranteed as to timely
distribution of principal and interest by Fannie Mae. In addition, Fannie Mae
will be obligated to distribute the principal balance of each class of REMIC
Certificates in full, whether or not sufficient funds are otherwise available.

      Freddie Mac guarantees the timely payment of interest on Freddie Mac REMIC
Certificates and also guarantees the payment of principal as payments are
required to be made on the underlying mortgage participation certificates
("PCs"). PCs represent undivided interests in specified level payment,
residential mortgages or participations therein purchased by Freddie Mac and
placed in a PC pool. With respect to principal payments on PCs, Freddie Mac
generally guarantees ultimate collection of all principal of the related
mortgage loans without offset or deduction. Freddie Mac also guarantees timely
payment of principal of certain PCs.

      CMOs and guaranteed REMIC Certificates issued by Fannie Mae and Freddie
Mac are types of multiple class Mortgage-Backed Securities. Investors may
purchase beneficial interests in REMICs, which are known as "regular" interests
or "residual" interests. The Underlying Funds do not intend to purchase residual
interests in REMICs. The REMIC Certificates represent beneficial ownership
interests in a REMIC trust, generally consisting of mortgage loans or Fannie
Mae, Freddie Mac or Ginnie Mae guaranteed Mortgage-Backed Securities (the
"Mortgage Assets"). The obligations of Fannie Mae or Freddie Mac under their
respective guaranty of the REMIC Certificates are obligations solely of Fannie
Mae or Freddie Mac, respectively.


                                      B-33
<PAGE>
 
      CMOs and REMIC Certificates are issued in multiple classes. Each class of
CMOs or REMIC Certificates, often referred to as a "tranche," is issued at a
specific adjustable or fixed interest rate and must be fully retired no later
than its final distribution date. Principal prepayments on the Mortgage Loans or
the Mortgage Assets underlying the CMOs or REMIC Certificates may cause some or
all of the classes of CMOs or REMIC Certificates to be retired substantially
earlier than their final distribution dates. Generally, interest is paid or
accrues on all classes of CMOs or REMIC Certificates on a monthly basis.

      The principal of and interest on the Mortgage Assets may be allocated
among the several classes of CMOs or REMIC Certificates in various ways. In
certain structures (known as "sequential pay" CMOs or REMIC Certificates),
payments of principal, including any principal prepayments, on the Mortgage
Assets generally are applied to the classes of CMOs or REMIC Certificates in the
order of their respective final distribution dates. Thus, no payment of
principal will be made on any class of sequential pay CMOs or REMIC Certificates
until all other classes having an earlier final distribution date have been paid
in full.

      Additional structures of CMOs and REMIC Certificates include, among
others, "parallel pay" CMOs and REMIC Certificates. Parallel pay CMOs or REMIC
Certificates are those which are structured to apply principal payments and
prepayments of the Mortgage Assets to two or more classes concurrently on a
proportionate or disproportionate basis. These simultaneous payments are taken
into account in calculating the final distribution date of each class.

      A wide variety of REMIC Certificates may be issued in parallel pay or
sequential pay structures. These securities include accrual certificates (also
known as "Z-Bonds"), which only accrue interest at a specified rate until all
other certificates having an earlier final distribution date have been retired
and are converted thereafter to an interest-paying security, and planned
amortization class ("PAC") certificates, which are parallel pay REMIC
Certificates that generally require that specified amounts of principal be
applied on each payment date to one or more classes or REMIC Certificates (the
"PAC Certificates"), even though all other principal payments and prepayments of
the Mortgage Assets are then required to be applied to one or more other classes
of the Certificates. The scheduled principal payments for the PAC Certificates
generally have the highest priority on each payment date after interest due has
been paid to all classes entitled to receive interest currently. Shortfalls, if
any, are added to the amount payable on the next payment date. The PAC
Certificate payment schedule is taken into account in calculating the final
distribution date of each class of PAC. In order to create PAC tranches, one or
more tranches generally must be created that absorb most of the volatility in
the underlying mortgage assets. These tranches tend to have market prices and
yields that are much more volatile than other PAC classes.

      Stripped Mortgage-Backed Securities. Certain of the Underlying Funds may
invest in stripped mortgage-backed securities ("SMBS"), which are derivative
multiclass mortgage securities, issued or guaranteed by the U.S. Government, its
agencies or instrumentalities or by private issuers. Although the market for
such securities is increasingly liquid, privately issued SMBS may not be readily
marketable and will be considered illiquid for purposes of an Underlying Fund's
limitation on investments in illiquid securities. An Underlying Fund's
investment adviser may determine that SMBS which are U.S. Government Securities
are liquid for purposes of each Fund's limitation on investments in illiquid
securities. The market value of the class consisting entirely of principal
payments generally is unusually volatile in response to changes in interest
rates. The yields on a class of SMBS that receives all or most of the interest
from Mortgage Assets are generally higher than prevailing market yields on other
Mortgage-Backed Securities because their cash flow patterns are more volatile
and there is a greater risk that the initial investment will not be fully
recouped.


                                      B-34

Asset-Backed Securities

      Asset-backed securities represent participation in, or are secured by and
payable from, assets such as motor vehicle installment sales, installment loan
contracts, leases of various types of real and personal property, receivables
from revolving credit (credit card) agreements and other categories of
receivables. Such assets are securitized through the use of trusts and special
purpose corporations. Payments or distributions of principal and interest may be
guaranteed up to certain amounts and for a certain time period by a letter of
credit or a pool insurance policy issued by a financial institution unaffiliated
with the trust or corporation, or other credit enhancements may be present.

      Certain Underlying Funds may invest in asset-backed securities. Like
Mortgage-Backed Securities, asset-backed securities are often subject to more
rapid repayment than their stated maturity date would indicate as a result of
the pass-through of prepayments of principal on the underlying loans. During
periods of declining interest rates, prepayment of loans underlying asset-backed
securities can be expected to accelerate. Accordingly, an Underlying Fund's
ability to maintain positions in such securities will be affected by reductions
in the principal amount of such securities resulting from prepayments, and its
ability to reinvest the returns of principal at comparable yields is subject to
generally prevailing interest rates at that time. To the extent that an
Underlying Fund invests in asset-backed securities, the values of such Fund's
portfolio securities will vary with changes in market interest rates generally
and the differentials in yields among various kinds of asset-backed securities.

      Asset-backed securities present certain additional risks that are not
presented by Mortgage-Backed Securities because asset-backed securities
generally do not have the benefit of a security interest in collateral that is
comparable to Mortgage Assets. Credit card receivables are generally unsecured
and the debtors on such receivables are entitled to the protection of a number
of state and federal consumer credit laws, many of which give such debtors the
right to set-off certain amounts owed on the credit cards, thereby reducing the
balance due. Automobile receivables generally are secured, but by automobiles
rather than residential real property. Most issuers of automobile receivables
permit the loan servicers to retain possession of the underlying obligations. If
the servicer were to sell these obligations to another party, there is a risk
that the purchaser would acquire an interest superior to that of the holders of
the asset-backed securities. In addition, because of the large number of
vehicles involved in a typical issuance and technical requirements under state
laws, the trustee for the holders of the automobile receivables may not have a
proper security interest in the underlying automobiles. Therefore, there is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

Futures Contracts and Options on Futures Contracts

      Each Underlying Fund may purchase and sell futures contracts and may also
purchase and write options on futures contracts. CORE Large Cap Value, CORE
Large Cap Growth and CORE Small Cap Equity Funds may only enter into such
transactions with respect to a representative index. CORE U.S. Equity Fund may
enter into futures transactions only with respect to the S&P 500 Index. The
other Funds may purchase and sell futures contracts based on various securities
(such as U.S. Government securities), securities indices, foreign currencies and
other financial instruments and indices. An Underlying Fund will engage in
futures and related options transactions, only for bona fide hedging purposes as
defined below or for purposes of seeking to increase total return to the extent
permitted by regulations of the Commodity Futures Trading Commission ("CFTC").
Futures contracts entered into by an Underlying Fund are traded on U.S.
exchanges or boards of trade that are licensed and regulated by the CFTC or on
foreign exchanges. Neither the CFTC, National Futures Association nor any
domestic exchange regulates activities of any foreign exchange or boards of
trade, including the execution, delivery and clearing of transactions, or has


                                      B-35
<PAGE>
 
the power to compel enforcement of the rules of a foreign exchange or board of
trade or any applicable foreign law. This is true even if the exchange is
formally linked to a domestic market so that a position taken on the market may
be liquidated by a transaction on another market. Moreover, such laws or
regulations will vary depending on the foreign country in which the foreign
futures or foreign options transaction occurs. For these reasons, persons who
trade foreign futures or foreign options contracts may not be afforded certain
of the protective measures provided by the Commodity Exchange Act, the CFTC's
regulations and the rules of the National Futures Association and any domestic
exchange, including the right to use reparations proceedings before the CFTC and
arbitration proceedings provided by the National Futures Association or any
domestic futures exchange. In particular, an Underlying Fund's investments in
foreign futures or foreign options transactions may not be provided the same
protections in respect of transactions on United States futures exchanges.

      Futures Contracts. A futures contract may generally be described as an
agreement between two parties to buy and sell particular financial instruments
or currencies for an agreed price during a designated month (or to deliver the
final cash settlement price, in the case of a contract relating to an index or
otherwise not calling for physical delivery at the end of trading in the
contract).

      When interest rates are rising or securities prices are falling, an
Underlying Fund can seek through the sale of futures contracts to offset a
decline in the value of its current portfolio securities. When rates are falling
or prices are rising, an Underlying Fund, through the purchase of futures
contracts, can attempt to secure better rates or prices than might later be
available in the market when it effects anticipated purchases. Similarly, an
Underlying Fund may purchase and sell futures contracts on a specified currency
in order to seek to increase total return or to hedge against changes in
currency exchange rates. An Underlying Fund may purchase futures contracts on
foreign currency to establish the price in U.S. dollars of a security quoted or
denominated in such currency that such Fund has acquired or expects to acquire.
The Underlying Fixed-Income Funds may also use futures contracts to manage their
term structure, sector selection and duration in accordance with their
investment objectives and policies.

      Positions taken in the futures market are not normally held to maturity,
but are instead liquidated through offsetting transactions which may result in a
profit or a loss. While an Underlying Fund will usually liquidate futures
contracts on securities or currency in this manner, an Underlying Fund may
instead make or take delivery of the underlying securities or currency whenever
it appears economically advantageous for the Underlying Fund to do so. A
clearing corporation associated with the exchange on which futures are traded
guarantees that, if still open, the sale or purchase will be performed on the
settlement date.

      Hedging Strategies. Hedging, by use of futures contracts, seeks to
establish with more certainty than would otherwise be possible the effective
price, rate of return or currency exchange rate on portfolio securities or
securities that an Underlying Fund owns or proposes to acquire. An Underlying
Fund may, for example, take a "short" position in the futures market by selling
futures contracts to seek to hedge against an anticipated rise in interest rates
or a decline in market prices or foreign currency rates that would adversely
affect the dollar value of such Fund's portfolio securities. Similarly, an
Underlying Fund may sell futures contracts on a currency in which its portfolio
securities are quoted or denominated or in one currency to seek to hedge against
fluctuations in the value of securities quoted or denominated in a different
currency if there is an established historical pattern of correlation between
the two currencies. If, in the opinion of an Underlying Fund's investment
adviser, there is a sufficient degree of correlation between price trends for an
Underlying Fund's portfolio securities and futures contracts based on other
financial instruments, securities indices or other indices, an Underlying Fund
may also enter into such futures contracts as part of its hedging strategy.
Although under some circumstances prices of securities in an 


                                      B-36
<PAGE>
 
Underlying Fund's portfolio may be more or less volatile than prices of such
futures contracts, its investment adviser will attempt to estimate the extent of
this volatility difference based on historical patterns and compensate for any
such differential by having an Underlying Fund enter into a greater or lesser
number of futures contracts or by attempting to achieve only a partial hedge
against price changes affecting an Underlying Fund's portfolio securities. When
hedging of this character is successful, any depreciation in the value of
portfolio securities will be substantially offset by appreciation in the value
of the futures position. On the other hand, any unanticipated appreciation in
the value of an Underlying Fund's portfolio securities would be substantially
offset by a decline in the value of the futures position.

      On other occasions, an Underlying Fund may take a "long" position by
purchasing such futures contracts. This would be done, for example, when an
Underlying Fund anticipates the subsequent purchase of particular securities
when it has the necessary cash, but expects the prices or currency exchange
rates then available in the applicable market to be less favorable than prices
or rates that are currently available.

      Options on Futures Contracts. The acquisition of put and call options on
futures contracts will give an Underlying Fund the right (but not the
obligation), for a specified price, to sell or to purchase, respectively, the
underlying futures contract at any time during the option period. As the
purchaser of an option on a futures contract, an Underlying Fund obtains the
benefit of the futures position if prices move in a favorable direction but
limits its risk of loss in the event of an unfavorable price movement to the
loss of the premium and transaction costs.

      The writing of a call option on a futures contract generates a premium
which may partially offset a decline in the value of an Underlying Fund's
assets. By writing a call option, an Underlying Fund becomes obligated, in
exchange for the premium, to sell a futures contract if the option is exercised,
which may have a value higher than the exercise price. Conversely, the writing
of a put option on a futures contract generates a premium, which may partially
offset an increase in the price of securities that an Underlying Fund intends to
purchase. However, an Underlying Fund becomes obligated upon exercise of the
option to purchase a futures contract if the option is exercised, which may have
a value lower than the exercise price. Thus, the loss incurred by an Underlying
Fund in writing options on futures is potentially unlimited and may exceed the
amount of the premium received. An Underlying Fund will incur transaction costs
in connection with the writing of options on futures.

      The holder or writer of an option on a futures contract may terminate its
position by selling or purchasing an offsetting option on the same financial
instrument. There is no guarantee that such closing transactions can be
effected. An Underlying Fund's ability to establish and close out positions on
such options will be subject to the development and maintenance of a liquid
market.

      Other Considerations. An Underlying Fund will engage in futures
transactions and related options transactions only for bona fide hedging as
defined in the regulations of the CFTC or to seek to increase total return to
the extent permitted by such regulations.

      In addition to bona fide hedging, a CFTC regulation permits an Underlying
Fund to engage in other futures transactions if the aggregate initial margin and
premiums required to establish such positions in futures contracts and options
on futures do not exceed 5% of the net asset value of such Fund's portfolio,
after taking into account unrealized profits and losses on any such positions
and excluding the amount by which such options were in-the-money at the time of
purchase. Transactions in futures contracts and related options may also be
limited by certain requirements that must be met in order for an Underlying Fund
to qualify as a regulated investment company for federal income tax purposes.


                                      B-37
<PAGE>
 
      Transactions in futures contracts and options on futures involve brokerage
costs, require margin deposits and, in certain cases, require the Underlying
Fund to segregate cash or liquid assets in an amount equal to the underlying
value of such contracts and options.

      While transactions in futures contracts and options on futures may reduce
certain risks, such transactions themselves entail certain other risks. Thus,
unanticipated changes in interest rates, securities prices or currency exchange
rates may result in a poorer overall performance for an Underlying Fund than if
it had not entered into any futures contracts or options transactions. In the
event of an imperfect correlation between a futures position and a portfolio
position which is intended to be protected, the desired protection may not be
obtained and an Underlying Fund may be exposed to risk of loss.

      Perfect correlation between an Underlying Fund's futures positions and
portfolio positions will be difficult to achieve because no futures contracts
based on individual equity or corporate fixed-income securities are currently
available. In addition, it is not possible for an Underlying Fund to hedge fully
or perfectly against currency fluctuations affecting the value of securities
quoted or denominated in foreign currencies because the value of such securities
is likely to fluctuate as a result of independent factors not related to
currency fluctuations. The profitability of a Fund's trading in futures depends
upon the ability of its investment adviser to analyze correctly the futures
markets.

Options on Securities and Securities Indices

      Writing Covered Options. Certain of the Underlying Funds may write (sell)
covered call and put options on any securities in which they may invest. An
Underlying Fund may purchase and write such options on securities that are
listed on national domestic securities exchanges or foreign securities exchanges
or traded in the over-the-counter market. A call option written by an Underlying
Fund obligates such Fund to sell specified securities to the holder of the
option at a specified price if the option is exercised at any time before the
expiration date. All call options written by an Underlying Fund are covered,
which means that such Fund will own the securities subject to the option as long
as the option is outstanding or such Fund will use the other methods described
below. An Underlying Fund's purpose in writing covered call options is to
realize greater income than would be realized on portfolio securities
transactions alone. However, an Underlying Fund may forego the opportunity to
profit from an increase in the market price of the underlying security.

      A put option written by an Underlying Fund would obligate such Fund to
purchase specified securities from the option holder at a specified price if the
option is exercised at any time before the expiration date. All put options
written by an Underlying Fund would be covered, which means that such Fund will
segregate cash or liquid assets with a value at least equal to the exercise
price of the put option or will use the other methods described below. The
purpose of writing such options is to generate additional income for the
Underlying Fund. However, in return for the option premium, each Fund accepts
the risk that it may be required to purchase the underlying securities at a
price in excess of the securities' market value at the time of purchase.

      Call and put options written by an Underlying Fund will also be considered
to be covered to the extent that the Underlying Fund's liabilities under such
options are wholly or partially offset by its rights under call and put options
purchased by the Underlying Fund or by an offsetting forward contract which, by
virtue of its exercise price or otherwise, reduces an Underlying Fund's net
exposure on its written option position.


                                      B-38
<PAGE>
 
      The Underlying Funds may also write (sell) covered call and put options on
any securities index consisting of securities in which it may invest. Options on
securities indices are similar to options on securities, except that the
exercise of securities index options requires cash payments and does not involve
the actual purchase or sale of securities. In addition, securities index options
are designed to reflect price fluctuations in a group of securities or segment
of the securities market rather than price fluctuations in a single security.

      An Underlying Fund may cover call options on a securities index by owning
securities whose price changes are expected to be similar to those of the
underlying index, or by having an absolute and immediate right to acquire such
securities without additional cash consideration (or for additional cash
consideration which has been segregated by the Underlying Fund) upon conversion
or exchange of other securities in its portfolio. An Underlying Fund may cover
call and put options on a securities index by segregating cash or liquid assets
with a value equal to the exercise price or by using the other methods described
above.

      An Underlying Fund may terminate its obligations under an exchange-traded
call or put option by purchasing an option identical to the one it has written.
Obligations under over-the-counter options may be terminated only by entering
into an offsetting transaction with the counterparty to such option. Such
purchases are referred to as "closing purchase transactions."

      Purchasing Options. Each Underlying Fund (other than Financial Square
Prime Obligations Fund) may purchase put and call options on any securities in
which it may invest or options on any securities index composed of securities in
which it may invest. An Underlying Fund would also be able to enter into closing
sale transactions in order to realize gains or minimize losses on options it had
purchased.

      An Underlying Fund may purchase call options in anticipation of an
increase in the market value of securities of the type in which it may invest.
The purchase of a call option would entitle an Underlying Fund, in return for
the premium paid, to purchase specified securities at a specified price during
the option period. An Underlying Fund would ordinarily realize a gain if, during
the option period, the value of such securities exceeded the sum of the exercise
price, the premium paid and transaction costs; otherwise such an Underlying Fund
would realize either no gain or a loss on the purchase of the call option.

      An Underlying Fund may purchase put options in anticipation of a decline
in the market value of securities in its portfolio ("protective puts"), or in
securities in which it may invest. The purchase of a put option would entitle an
Underlying Fund, in exchange for the premium paid, to sell specified securities
at a specified price during the option period. The purchase of protective puts
is designed to offset or hedge against a decline in the market value of an
Underlying Fund's securities. Put options may also be purchased by an Underlying
Fund for the purpose of affirmatively benefiting from a decline in the price of
securities which it does not own. An Underlying Fund would ordinarily realize a
gain if, during the option period, the value of the underlying securities
decreased below the exercise price sufficiently to more than cover the premium
and transaction costs; otherwise such an Underlying Fund would realize either no
gain or a loss on the purchase of the put option. Gains and losses on the
purchase of protective put options would tend to be offset by countervailing
changes in the value of the underlying portfolio securities.

      An Underlying Fund would purchase put and call options on securities
indices for the same purposes as it would purchase options on individual
securities. For a description of options on securities indices, see "Writing
Covered Options" above.


                                      B-39
<PAGE>
 
      Yield Curve Options. Each Underlying Fixed-Income Fund and Real Estate
Securities Fund may enter into options on the yield "spread" or differential
between two securities. Such transactions are referred to as "yield curve"
options. In contrast to other types of options, a yield curve option is based on
the difference between the yields of designated securities, rather than the
prices of the individual securities, and is settled through cash payments.
Accordingly, a yield curve option is profitable to the holder if this
differential widens (in the case of a call) or narrows (in the case of a put),
regardless of whether the yields of the underlying securities increase or
decrease.

      An Underlying Fund may purchase or write yield curve options for the same
purposes as other options on securities. For example, an Underlying Fund may
purchase a call option on the yield spread between two securities if the
Underlying Fund owns one of the securities and anticipates purchasing the other
security and wants to hedge against an adverse change in the yield spread
between the two securities. An Underlying Fund may also purchase or write yield
curve options in an effort to increase current income if, in the judgment of its
investment adviser, the Underlying Fund will be able to profit from movements in
the spread between the yields of the underlying securities. The trading of yield
curve options is subject to all of the risks associated with the trading of
other types of options. In addition, however, such options present risk of loss
even if the yield of one of the underlying securities remains constant, or if
the spread moves in a direction or to an extent which was not anticipated.

      Yield curve options written by an Underlying Fund will be "covered." A
call (or put) option is covered if an Underlying Fund holds another call (or
put) option on the spread between the same two securities and segregates cash or
liquid assets sufficient to cover the Underlying Fund's net liability under the
two options. Therefore, an Underlying Fund's liability for such a covered option
is generally limited to the difference between the amount of the Underlying
Fund's liability under the option written by the Underlying Fund less the value
of the option held by the Underlying Fund. Yield curve options may also be
covered in such other manner as may be in accordance with the requirements of
the counterparty with which the option is traded and applicable laws and
regulations. Yield curve options are traded over-the-counter, and the trading
markets for these options may not be as developed.

      Risks Associated with Options Transactions. There is no assurance that a
liquid secondary market on a domestic or foreign options exchange will exist for
any particular exchange-traded option or at any particular time. If an
Underlying Fund is unable to effect a closing purchase transaction with respect
to covered options it has written, the Underlying Fund will not be able to sell
the underlying securities or dispose of segregated assets until the options
expire or are exercised. Similarly, if an Underlying Fund is unable to effect a
closing sale transaction with respect to options it has purchased, it will have
to exercise the options in order to realize any profit and will incur
transaction costs upon the purchase or sale of underlying securities.

      Reasons for the absence of a liquid secondary market on an exchange
include the following: (i) there may be insufficient trading interest in certain
options; (ii) restrictions may be imposed by an exchange on opening or closing
transactions or both; (iii) trading halts, suspensions or other restrictions may
be imposed with respect to particular classes or series of options; (iv) unusual
or unforeseen circumstances may interrupt normal operations on an exchange; (v)
the facilities of an exchange or the Options Clearing Corporation may not at all
times be adequate to handle current trading volume; or (vi) one or more
exchanges could, for economic or other reasons, decide or be compelled at some
future date to discontinue the trading of options (or a particular class or
series of options), in which event the secondary market on that exchange (or in
that class or series of options) would cease to exist, although outstanding
options on that exchange that had been issued by the Options Clearing
Corporation as a result of trades on that exchange would continue to be
exercisable in accordance with their terms.


                                      B-40
<PAGE>
 
      An Underlying Fund may purchase and sell both options that are traded on
U.S. and foreign exchanges and options traded over-the-counter with
broker-dealers who make markets in these options. The ability to terminate
over-the-counter options is more limited than with exchange-traded options and
may involve the risk that broker-dealers participating in such transactions will
not fulfill their obligations.

      Transactions by an Underlying Fund in options will be subject to
limitations established by each of the exchanges, boards of trade or other
trading facilities governing the maximum number of options in each class which
may be written or purchased by a single investor or group of investors acting in
concert. Thus, the number of options which an Underlying Fund may write or
purchase may be affected by options written or purchased by other investment
advisory clients of the Underlying Funds' investment advisers. An exchange,
board of trade or other trading facility may order the liquidation of positions
found to be in excess of these limits, and it may impose certain other
sanctions.

      The writing and purchase of options is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions. The use of options to seek to
increase total return involves the risk of loss if an investment adviser is
incorrect in its expectation of fluctuations in securities prices or interest
rates. The successful use of options for hedging purposes also depends in part
on the ability of an investment adviser to predict future price fluctuations and
the degree of correlation between the options and securities markets. If an
investment adviser is incorrect in its expectation of changes in securities
prices or determination of the correlation between the securities indices on
which options are written and purchased and the securities in a Fund's
investment portfolio, the investment performance of the Fund will be less
favorable than it would have been in the absence of such options transactions.
The writing of options could increase a Fund's portfolio turnover rate and,
therefore, associated brokerage commissions or spreads.

Warrants and Stock Purchase Rights

      Certain of the Underlying Funds may invest a portion of their assets in
warrants or rights (including those acquired in units or attached to other
securities) which entitle the holder to buy equity securities at a specific
price for a specific period of time. An Underlying Fund will invest in warrants
and rights only if such securities are deemed appropriate by its investment
adviser for investment by the Underlying Fund. Warrants and rights have no
voting rights, receive no dividends and have no rights with respect to the
assets of the issuer.

Foreign Investments

      Investments in foreign securities may offer potential benefits not
available from investments solely in U.S. dollar-denominated or quoted
securities of domestic issuers. Such benefits may include the opportunity to
invest in foreign issuers that appear, in the opinion of an Underlying Fund's
investment adviser, to offer the potential for long-term growth of capital and
income than investments in U.S. securities, the opportunity to invest in foreign
countries with economic policies or business cycles different from those of the
United States and the opportunity to reduce fluctuations in portfolio value by
taking advantage of foreign securities markets that do not necessarily move in a
manner parallel to U.S. markets.

      Investing in foreign securities also involves, however, certain special
considerations, including those set forth below, which are not typically
associated with investing in U.S. dollar-denominated or quoted securities of
U.S. issuers. Investments in foreign securities usually involve currencies of
foreign countries. Accordingly, any Underlying Fund that invests in foreign
securities may be affected favorably or 


                                      B-41
<PAGE>
 
unfavorably by changes in currency rates and in exchange control regulations and
may incur costs in connection with conversions between various currencies. An
Underlying Fund may be subject to currency exposure independent of its
securities positions.

      Currency exchange rates may fluctuate significantly over short periods of
time. They generally are determined by the forces of supply and demand in the
foreign exchange markets and the relative merits of investments in different
countries, actual or anticipated changes in interest rates and other complex
factors, as seen from an international perspective. Currency exchange rates also
can be affected unpredictably by intervention by U.S. or foreign governments or
central banks or the failure to intervene or by currency controls or political
developments in the United States or abroad. To the extent that a substantial
portion of an Underlying Fund's total assets, adjusted to reflect the Underlying
Fund's net position after giving effect to currency transactions, is denominated
or quoted in the currencies of foreign countries, the Underlying Fund will be
more susceptible to the risk of adverse economic and political developments
within those countries. In addition, if the currency in which an Underlying Fund
receives dividends, interest or other payment declines in value against the U.S.
dollar before such income is distributed as dividends to shareholders or
converted to U.S. dollars, the Underlying Fund may have to sell portfolio
securities to obtain sufficient cash to pay such dividends.

      Since foreign issuers generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies, there may be less publicly
available information about a foreign company than about a U.S. company. Volume
and liquidity in most foreign securities markets are less than in the United
States and securities of many foreign companies are less liquid and more
volatile than securities of comparable U.S. companies. Fixed commissions on
foreign securities exchanges are generally higher than negotiated commissions on
U.S. exchanges, although each Underlying Fund endeavors to achieve the most
favorable net results on its portfolio transactions. There is generally less
government supervision and regulation of foreign securities exchanges, brokers,
dealers and listed and unlisted companies than in the United States. For
example, there may be no comparable provisions under certain foreign laws to
insider trading and similar investor protection securities laws that apply with
respect to securities transactions consummated in the United States. Mail
service between the United States and foreign countries may be slower or less
reliable than within the United States, thus increasing the risk of delayed
settlement of portfolio transactions or loss of certificates for portfolio
securities.

      Foreign markets also have different clearance and settlement procedures,
and in certain markets there have been times when settlements have been unable
to keep pace with the volume of securities transactions, making it difficult to
conduct such transactions. Such delays in settlement could result in temporary
periods when some of an Underlying Fund's assets are uninvested and no return is
earned on such assets. The inability of an Underlying Fund to make intended
security purchases due to settlement problems could cause the Underlying Fund to
miss attractive investment opportunities. Inability to dispose of portfolio
securities due to settlement problems could result either in losses to an
Underlying Fund due to subsequent declines in value of the portfolio securities
or, if the Underlying Fund has entered into a contract to sell the securities,
could result in possible liability to the purchaser. In addition, with respect
to certain foreign countries, there is the possibility of expropriation or
confiscatory taxation, political or social instability, or diplomatic
developments which could affect an Underlying Fund's investments in those
countries. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, capital reinvestment, resource self-sufficiency and
balance of payments position.


                                      B-42
<PAGE>
 
      Investments in foreign securities may take the form of sponsored and
unsponsored American Depository Receipts ("ADRs"), Global Depository Receipts
("GDRs"), European Depository Receipts ("EDRs") or other similar instruments
representing securities of foreign issuers (together, "Depository Receipts").

      ADRs represent the right to receive securities of foreign issuers
deposited in a domestic bank or a correspondent bank. ADRs are traded on
domestic exchanges or in the U.S. over-the-counter market and, generally, are in
registered form. EDRs and GDRs are receipts evidencing an arrangement with a
non-U.S. bank similar to that for ADRs and are designed for use in the non-U.S.
securities markets. EDRs and GDRs are not necessarily quoted in the same
currency as the underlying security.

      To the extent an Underlying Fund acquires Depository Receipts through
banks which do not have a contractual relationship with the foreign issuer of
the security underlying the Depository Receipts to issue and service such
Depository Receipts (unsponsored), there may be an increased possibility that
the Underlying Fund would not become aware of and be able to respond to
corporate actions such as stock splits or rights offerings involving the foreign
issuer in a timely manner. In addition, the lack of information may result in
inefficiencies in the valuation of such instruments.

      As described more fully below, certain of the Underlying Funds may invest
in countries with emerging economies or securities markets. Political and
economic structures in many of such countries may be undergoing significant
evolution and rapid development, and such countries may lack the social,
political and economic stability characteristic of more developed countries.
Certain of such countries may have in the past failed to recognize private
property rights and have at times nationalized or expropriated the assets of
private companies. As a result, the risks described above, including the risks
of nationalization or expropriation of assets, may be heightened. See "Investing
in Emerging Markets" below.

      Investing in Emerging Markets. CORE International Equity, International
Equity, European Equity, Japanese Equity, International Small Cap, Emerging
Markets Equity and Asia Growth Funds are intended for long-term investors who
can accept the risks associated with investing primarily in equity and
equity-related securities of foreign issuers, including (for certain Funds)
emerging country issuers, as well as the risks associated with investments
quoted or denominated in foreign currencies. Growth and Income, Capital Growth,
Mid Cap Value, Small Cap Value and Real Estate Securities Funds may invest, to a
lesser extent, in equity and equity-related securities of foreign issuers,
including emerging country issuers. The Core Fixed Income, Global Income and
High Yield Funds may invest in debt securities of foreign issuers, including
emerging country issuers, and in fixed income securities quoted or denominated
in a currency other than U.S. dollars.

      Investments in securities of emerging market issuers involve special
risks. The development of a market for such securities is a relatively recent
phenomenon, and each of the securities markets of the emerging countries is less
liquid and subject to greater price volatility and has a smaller market
capitalization than the U.S. securities markets. Issuers and securities markets
in such countries are not subject to as extensive and frequent accounting,
financial and other reporting requirements or as comprehensive government
regulations as are issuers and securities markets in the U.S. In particular, the
assets and profits appearing on the financial statements of emerging country
issuers may not reflect their financial position or results of operations in the
same manner as financial statements for U.S. issuers. Substantially less
information may be publicly available about emerging country issuers than is
available about issuers in the United States.


                                      B-43
<PAGE>
 
      Emerging country securities markets are typically marked by a high
concentration of market capitalization and trading volume in a small number of
issuers representing a limited number of industries, as well as a high
concentration of ownership of such securities by a limited number of investors.
The markets for securities in certain emerging countries are in the earliest
stages of their development. A Fund's investments in emerging countries are
subject to the risk that the liquidity of particular instruments, or instruments
generally in such countries, will shrink or disappear suddenly and without
warning as a result of adverse economic, market or political conditions, or
adverse investing perceptions, whether or not accurate. Even the markets for
relatively widely traded securities in emerging countries may not be able to
absorb, without price disruptions, a significant increase in trading volume or
trades of a size customarily undertaken by institutional investors in the
securities markets of developed countries. The limited size of many of the
securities markets can cause prices to be erratic for reasons apart from factors
that affect the soundness and competitiveness of the securities issuers. For
example, prices may be unduly influenced by traders who control prices in these
markets. Additionally, market making and arbitrage activities are generally less
extensive in such markets, which may contribute to increased volatility and
reduced liquidity of such markets. The limited liquidity of emerging country
securities may also affect an Underlying Fund's ability to accurately value its
portfolio securities or to acquire or dispose of such securities at the price
and times it wishes to do so. The risks associated with reduced liquidity may be
particularly acute to the extent that an Underlying Fund needs cash to meet
redemption requests, to pay dividends and other distributions or to pay its
expenses.

      Transaction costs, including brokerage commissions or dealer mark-ups, in
emerging countries may be higher than in the United States and other developed
securities markets. In addition, existing laws and regulations are often
inconsistently applied. As legal systems in emerging countries develop, foreign
investors may be adversely affected by new or amended laws and regulations. In
circumstances where adequate laws exist, it may not be possible to obtain swift
and equitable enforcement of the law.

      With respect to investment in certain emerging market countries, archaic
legal systems may have an adverse impact on an Underlying Fund. For example,
while the potential liability of a shareholder in a U.S. corporation with
respect to acts of the corporation is generally limited to the amount of the
shareholder's investment, the notion of limited liability is less clear in
certain emerging market countries. Similarly, the rights of investors in
emerging market companies may be more limited than those of shareholders of U.S.
corporations.

      Foreign investment in the securities markets of certain emerging countries
is restricted or controlled to varying degrees. These restrictions may limit an
Underlying Fund's investment in certain emerging countries and may increase the
expenses of the Underlying Fund. Certain emerging countries require governmental
approval prior to investments by foreign persons or limit investment by foreign
persons to only a specified percentage of an issuer's outstanding securities or
a specific class of securities which may have less advantageous terms (including
price) than securities of the company available for purchase by nationals. In
addition, the repatriation of both investment income and capital from several of
the emerging countries is subject to restrictions which require governmental
consents or prohibit repatriation entirely for a period of time. Even where
there is no outright restriction on repatriation of capital, the mechanics of
repatriation may affect certain aspects of the operation of an Underlying Fund.
An Underlying Fund may be required to establish special custodial or other
arrangements before investing in certain emerging countries.

      Each of the emerging countries may be subject to a greater degree of
economic, political and social instability than is the case in the United
States, Japan and most Western European countries. This instability may result
from, among other things, the following: (i) authoritarian governments or
military 


                                      B-44
<PAGE>
 
involvement in political and economic decision making, including changes or
attempted changes in governments through extra-constitutional means; (ii)
popular unrest associated with demands for improved political, economic or
social conditions; (iii) internal insurgencies; (iv) hostile relations with
neighboring countries; (v) ethnic, religious and racial disaffection or
conflict; and (vi) the absence of developed legal structures governing foreign
private investments and private property. Such economic, political and social
instability could disrupt the principal financial markets in which the
Underlying Funds may invest and adversely affect the value of the Underlying
Funds' assets. A Fund's investments could in the future be adversely affected by
any increase in taxes or by political, economic or diplomatic developments.
Certain Funds intend to seek investment opportunities within the former "east
bloc" countries in Eastern Europe. See "Fund Investment Objective and Policies"
in the Fund's prospectus. All or a substantial portion of such investments may
be considered "not readily marketable" for purposes of the limitations set forth
below. For example, most Eastern European countries have had a centrally
planned, socialist economy since shortly after World War II. The governments of
a number of Eastern European countries currently are implementing reforms
directed at political and economic liberalization, including efforts to
decentralize the economic decision-making process and move towards a market
economy. However, business entities in many Eastern European countries do not
have any recent history of operating in a market-oriented economy, and the
ultimate impact of Eastern European countries' attempts to move toward more
market-oriented economies is currently unclear. In addition, any change in the
leadership or policies of Eastern European countries may halt the expansion of
or reverse the liberalization of foreign investment policies now occurring and
adversely affect existing investment opportunities. To the extent an Underlying 
Fund invests in an issuer located (1) in a country which was formerly part of 
Yugoslavia, (2) in a country that shares a border with the former country of 
Yugoslavia, (3) in a country which is a member of the North Atlantic Treaty
Organizaton ("NATO"), or (4) in other countries in Europe, such Underlying Fund
could suffer investment losses as a result of the recent conflict between Serbia
and the members of NATO. The NATO bombing campaign and proposed oil embargo (if
implemented) could adversely affect an Underlying Fund's investments. The extent
to which this conflict may broaden and involve other countries such as Russia is
unpredictable, and the impact this conflict may have on an Underlying Fund is
uncertain.

      The economies of emerging countries may differ unfavorably from the U.S.
economy in such respects as growth of gross domestic product, rate of inflation,
capital reinvestment, resources, self-sufficiency and balance of payments. Many
emerging countries have experienced in the past, and continue to experience,
high rates of inflation. In certain countries inflation has at times accelerated
rapidly to hyperinflationary levels, creating a negative interest rate
environment and sharply eroding the value of outstanding financial assets in
those countries. The economies of many emerging countries are heavily dependent
upon international trade and are accordingly affected by protective trade
barriers and the economic conditions of their trading partners. In addition, the
economies of some emerging countries are vulnerable to weakness in world prices
for their commodity exports.

      An Underlying Fund's income and, in some cases, capital gains from foreign
stocks and securities will be subject to applicable taxation in certain of the
countries in which it invests, and treaties between the U.S. and such countries
may not be available in some cases to reduce the otherwise applicable tax rates.

      Foreign markets may also have different clearance and settlement
procedures and in certain U.S. markets, there have been times when settlements
have been unable to keep pace with the volume of securities transactions making
it difficult to conduct such transactions. Delays in settlement could result in
temporary periods when a portion of an Underlying Fund's assets is uninvested
and no return is earned thereon. The inability of an Underlying Fund to make
intended security purchases or sales due to settlement problems could result
either in losses to the Underlying Fund due to subsequent declines in value of
the portfolio securities or, if the Underlying Fund has entered into a contract
to sell the securities, could result in possible liability of the Underlying
Fund to the purchaser. The creditworthiness of the local securities firms used
by a Fund in emerging countries may not be as sound as the creditworthiness of
firms used in more developed countries, thus subjecting the Fund to a greater
risk if a securities firm defaults in the performance of its responsibilities.

      Investing in Japan. The Japanese Equity Fund invests in the equity
securities of Japanese companies. Japan's economy, the second-largest in the
world, has grown substantially over the last three 


                                      B-45
<PAGE>
 
decades. The boom in Japan's equity and property markets during the expansion of
the late 1980's supported high rates of investment and consumer spending on
durable goods, but both of these components of demand have now retreated sharply
following the decline in asset prices. Profits have fallen sharply, unemployment
has reached a historical high and consumer confidence is low. The banking sector
continues to suffer from non-performing loans and this economy is subject to
deflationary pressures. Numerous discount-rate cuts since its peak in 1991, a
succession of fiscal stimulus packages, support plans for the debt-burdened
financial system and spending for reconstruction following the Kobe earthquake
may help to contain the recessionary forces, but substantial uncertainties
remain.

      In addition to the cyclical downturn, Japan is suffering through
structural adjustments. The Japanese have seen a deterioration of their
competitiveness due to high wages, a strong currency and structural rigidities.
Finally, Japan is reforming its political process and deregulating its economy.
This has brought about turmoil, uncertainty and a crisis of confidence.

      While the Japanese governmental system itself seems stable, the dynamics
of the country's politics have been unpredictable in recent years. The economic
crisis of 1990-92 brought the downfall of the conservative Liberal Democratic
Party, which had ruled since 1955. Since then, the country has seen a series of
unstable multi-party coalitions and several prime ministers come and go, because
of politics as well as personal scandals. While there appears to be no reason
for anticipating civic unrest, it is impossible to know when the political
instability will end and what trade and fiscal policies might be pursued by the
government that emerges.

      Japan's heavy dependence on international trade has been adversely
affected by trade tariffs and other protectionist measures as well as the
economic condition of its trading partners. While Japan subsidizes its
agricultural industry, only 19% of its land is suitable for cultivation and it
is only 50% self-sufficient in food production. Accordingly, it is highly
dependent on large imports of wheat, sorghum and soybeans. In addition,
industry, its most important economic sector, depends on imported raw materials
and fuels, including iron ore, copper, oil and many forest products. Japan's
high volume of exports, such as automobiles, machine tools and semiconductors,
have caused trade tensions, particularly with the United States. Some trade
agreements, however, have been implemented to reduce these tensions. The
relaxing of official and de facto barriers to imports, or hardships created by
any pressures brought by trading partners, could adversely affect Japan's
economy. A substantial rise in world oil or commodity prices could also have a
negative affect. The strength of the yen itself may prove an impediment to
strong continued exports and economic recovery, because it makes Japanese goods
sold in other countries more expensive and reduces the value of foreign earnings
repatriated to Japan. Because the Japanese economy is so dependent on exports,
any fall-off in exports may be seen as a sign of economic weakness, which may
adversely affect the market.

      Geologically, Japan is located in a volatile area of the world, and has
historically been vulnerable to earthquakes, volcanoes and other natural
disasters. As demonstrated by the Kobe earthquake in January of 1995, in which
5,000 people were killed and billions of dollars of damage was sustained, these
natural disasters can be significant enough to affect the country's economy.

      Sovereign Debt Obligations. Investments in sovereign debt obligations
involve special risks not present in corporate debt obligations. The issuer of
the sovereign debt or the governmental authorities that control the repayment of
the debt may be unable or unwilling to repay principal or interest when due, and
an Underlying Fund may have limited recourse in the event of a default. During
periods of economic uncertainty, the market prices of sovereign debt, and an
Underlying Fund's net asset value, may be more volatile than prices of debt
obligations of U.S. issuers. In the past, the governments of certain emerging


                                      B-46
<PAGE>
 
markets have encountered difficulties in servicing their debt obligations,
withheld payments of principal and interest and declared moratoria on the
payment of principal and interest on their sovereign debts.

      A sovereign debtor's willingness or ability to repay principal and pay
interest in a timely manner may be affected by, among other factors, its cash
flow situation, the extent of its foreign currency reserves, the availability of
sufficient foreign exchange, the relative size of the debt service burden, the
sovereign debtor's policy toward principal international lenders and local
political constraints. Sovereign debtors may also be dependent on expected
disbursements from foreign governments, multinational agencies and other
entities to reduce principal and interest arrearages on their debt. The failure
of a sovereign debtor to implement economic reforms, achieve specified levels of
economic performance or repay principal or interest when due may result in the
cancellation of the third parties' commitments to lend funds to the sovereign
debtor, which may further impair such debtor's ability or willingness to timely
service its debts.

      Brady Bonds. Certain foreign debt obligations, customarily referred to as
"Brady Bonds," are created through the exchange of existing commercial bank
loans to foreign entities for new obligations in connection with debt
restructuring under a plan introduced by former U.S. Secretary of the Treasury,
Nicholas F. Brady (the "Brady Plan"). Brady Bonds may be fully or partially
collateralized or uncollateralized and issued in various currencies (although
most are U.S. dollar denominated). In the event of a default on collateralized
Brady Bonds for which obligations are accelerated, the collateral for the
payment of principal will not be distributed to investors, nor will such
obligations be sold and the proceeds distributed. The collateral will be held by
the collateral agent to the scheduled maturity of the defaulted Brady Bonds,
which will continue to be outstanding, at which time the face amount of the
collateral will equal the principal payments which would have then been due on
the Brady Bonds in the normal course. In light of the residual risk of the Brady
Bonds and, among other factors, the history of default with respect to
commercial bank loans by public and private entities of countries issuing Brady
Bonds, investments in Brady Bonds may be speculative.

      Forward Foreign Currency Exchange Contracts. Certain of the Underlying
Funds may enter into forward foreign currency exchange contracts for hedging
purposes and to seek to protect against anticipated changes in future foreign
currency exchange rates. Certain of the Underlying Funds may also enter into
forward foreign currency exchange contracts to seek to increase total return. A
forward foreign currency exchange contract involves an obligation to purchase or
sell a specific currency at a future date, which may be any fixed number of days
from the date of the contract agreed upon by the parties, at a price set at the
time of the contract. These contracts are traded in the interbank market between
currency traders (usually large commercial banks) and their customers. A forward
contract generally has no deposit requirement, and no commissions are generally
charged at any stage for trades.

      At the maturity of a forward contract an Underlying Fund may either accept
or make delivery of the currency specified in the contract or, at or prior to
maturity, enter into a closing transaction involving the purchase or sale of an
offsetting contract. Closing transactions with respect to forward contracts are
often, but not always, effected with the currency trader who is a party to the
original forward contract.

      An Underlying Fund may enter into forward foreign currency exchange
contracts in several circumstances. First, when an Underlying Fund enters into a
contract for the purchase or sale of a security denominated or quoted in a
foreign currency, or when an Underlying Fund anticipates the receipt in a
foreign currency of dividend or interest payments on such a security which it
holds, the Underlying Fund may desire to "lock in" the U.S. dollar price of the
security or the U.S. dollar equivalent of such dividend or interest payment, as
the case may be. By entering into a forward contract for the purchase or sale,
for a fixed amount of dollars, of the amount of foreign currency involved in the
underlying transactions, the


                                      B-47
<PAGE>
 
Underlying Fund will attempt to protect itself against an adverse change in the
relationship between the U.S. dollar and the subject foreign currency during the
period between the date on which the security is purchased or sold, or on which
the dividend or interest payment is declared, and the date on which such
payments are made or received.

      Additionally, when an Underlying Fund's investment adviser believes that
the currency of a particular foreign country may suffer a substantial decline
against the U.S. dollar, it may enter into a forward contract to sell, for a
fixed amount of U.S. dollars, the amount of foreign currency approximating the
value of some or all of an Underlying Fund's portfolio securities quoted or
denominated in such foreign currency. The precise matching of the forward
contract amounts and the value of the securities involved will not generally be
possible because the future value of such securities in foreign currencies will
change as a consequence of market movements in the value of those securities
between the date on which the contract is entered into and the date it matures.
Using forward contracts to protect the value of an Underlying Fund's portfolio
securities against a decline in the value of a currency does not eliminate
fluctuations in the underlying prices of the securities. It simply establishes a
rate of exchange which an Underlying Fund can achieve at some future point in
time. The precise projection of short-term currency market movements is not
possible, and short-term hedging provides a means of fixing the U.S. dollar
value of only a portion of an Underlying Fund's foreign assets.

      Certain of the Underlying Funds may engage in cross-hedging by using
forward contracts in one currency to hedge against fluctuations in the value of
securities quoted or denominated in a different currency if an Underlying Fund's
investment adviser determines that there is a pattern of correlation between the
two currencies. These Funds may also purchase and sell forward contracts to seek
to increase total return when an Underlying Fund's investment adviser
anticipates that the foreign currency will appreciate or depreciate in value,
but securities quoted or denominated in that currency do not present attractive
investment opportunities and are not held in the Underlying Fund's portfolio.

      Unless otherwise covered, cash or liquid assets of an Underlying Fund will
be segregated in an amount equal to the value of the Underlying Fund's total
assets committed to the consummation of forward foreign currency exchange
contracts requiring the Fund to purchase foreign currencies and forward
contracts entered into to seek to increase total return. The segregated assets
will be marked-to-market. If the value of the segregated assets declines,
additional liquid assets will be segregated so that the value will equal the
amount of an Underlying Fund's commitments with respect to such contracts.
Although the contracts are not presently regulated by the CFTC, the CFTC may in
the future assert authority to regulate these contracts. In such event, an
Underlying Fund's ability to utilize forward foreign currency exchange contracts
may be restricted. Certain of the Underlying Funds will not enter into a forward
contract with a term of greater than one year.

      While an Underlying Fund may enter into forward contracts to reduce
currency exchange rate risks, transactions in such contracts involve certain
other risks. Thus, while an Underlying Fund may benefit from such transactions,
unanticipated changes in currency prices may result in a poorer overall
performance for the Underlying Fund than if it had not engaged in any such
transactions. Moreover, there may be imperfect correlation between an Underlying
Fund's portfolio holdings of securities quoted or denominated in a particular
currency and forward contracts entered into by such Fund. Such imperfect
correlation may cause an Underlying Fund to sustain losses which will prevent
the Underlying Fund from achieving a complete hedge or expose the Underlying
Fund to risk of foreign exchange loss.

      Markets for trading foreign forward currency contracts offer less
protection against defaults than is available when trading in currency
instruments on an exchange. Forward contracts are subject to the risk 


                                      B-48
<PAGE>
 
that the counterparty to such contract will default on its obligations. Since a
forward foreign currency exchange contract is not guaranteed by an exchange or
clearinghouse, a default on the contract would deprive an Underlying Fund of
unrealized profits, transaction costs or the benefits of a currency hedge or
force the Underlying Fund to cover its purchase or sale commitments, if any, at
the current market price.

      Forward contracts are subject to the risk that the counterparty to such
contract will default on its obligations. Since a forward foreign currency
exchange contract is not guaranteed by an exchange or clearinghouse, a default
on the contract would deprive an Underlying Fund of unrealized profits,
transaction costs or the benefits of a currency hedge or force the Underlying
Fund to cover its purchase or sale commitments, if any, at the current market
price. An Underlying Fund will not enter into such transactions unless the
credit quality of the unsecured senior debt or the claims-paying ability of the
counterparty is considered to be investment grade by its investment adviser.

      Writing and Purchasing Currency Call and Put Options. Certain of the
Underlying Funds may, to the extent that they invest in foreign securities,
write and purchase put and call options on foreign currencies for the purpose of
protecting against declines in the U.S. dollar value of foreign portfolio
securities and against increases in the U.S. dollar cost of foreign securities
to be acquired. As with other kinds of option transactions, however, the writing
of an option on foreign currency will constitute only a partial hedge, up to the
amount of the premium received. If and when an Underlying Fund seeks to close
out an option, the Underlying Fund could be required to purchase or sell foreign
currencies at disadvantageous exchange rates, thereby incurring losses. The
purchase of an option on foreign currency may constitute an effective hedge
against exchange rate fluctuations; however, in the event of exchange rate
movements adverse to an Underlying Fund's position, the Underlying Fund may
forfeit the entire amount of the premium plus related transaction costs. Options
on foreign currencies written or purchased by an Underlying Fund will be traded
on U.S. and foreign exchanges or over-the-counter.

      Options on currency may be used for either hedging or cross-hedging
purposes, which involves writing or purchasing options on one currency to hedge
against changes in exchange rates for a different currency with a pattern of
correlation, or to seek to increase total return when an Underlying Fund's
investment adviser anticipates that the currency will appreciate or depreciate
in value, but the securities quoted or denominated in that currency do not
present attractive investment opportunities and are not included in the
Underlying Fund's portfolio.

      A call option written by an Underlying Fund obligates an Underlying Fund
to sell a specified currency to the holder of the option at a specified price if
the option is exercised before the expiration date. A put option written by an
Underlying Fund would obligate an Underlying Fund to purchase a specified
currency from the option holder at a specified price if the option is exercised
at any time before the expiration date. The writing of currency options involves
a risk that an Underlying Fund will, upon exercise of the option, be required to
sell currency subject to a call at a price that is less than the currency's
market value or be required to purchase currency subject to a put at a price
that exceeds the currency's market value. For a description of how to cover
written put and call options, see "Writing Covered Options" above.

      An Underlying Fund may terminate its obligations under a call or put
option by purchasing an option identical to the one it has written. Such
purchases are referred to as "closing purchase transactions." An Underlying Fund
may enter into closing sale transactions in order to realize gains or minimize
losses on options purchased by the Underlying Fund.


                                      B-49
<PAGE>
 
      An Underlying Fund would normally purchase call options on foreign
currency in anticipation of an increase in the U.S. dollar value of currency in
which securities to be acquired by an Underlying Fund are quoted or denominated.
The purchase of a call option would entitle the Underlying Fund, in return for
the premium paid, to purchase specified currency at a specified price during the
option period. An Underlying Fund would ordinarily realize a gain if, during the
option period, the value of such currency exceeded the sum of the exercise
price, the premium paid and transaction costs; otherwise the Underlying Fund
would realize either no gain or a loss on the purchase of the call option.

      An Underlying Fund would normally purchase put options in anticipation of
a decline in the U.S. dollar value of currency in which securities in its
portfolio are quoted or denominated ("protective puts"). The purchase of a put
option would entitle an Underlying Fund, in exchange for the premium paid, to
sell specified currency at a specified price during the option period. The
purchase of protective puts is designed merely to offset or hedge against a
decline in the dollar value of an Underlying Fund's portfolio securities due to
currency exchange rate fluctuations. An Underlying Fund would ordinarily realize
a gain if, during the option period, the value of the underlying currency
decreased below the exercise price sufficiently to more than cover the premium
and transaction costs; otherwise the Underlying Fund would realize either no
gain or a loss on the purchase of the put option. Gains and losses on the
purchase of protective put options would tend to be offset by countervailing
changes in the value of underlying currency or portfolio securities.

      In addition to using options for the hedging purposes described above,
certain Underlying Funds may use options on currency to seek to increase total
return. These Funds may write (sell) covered put and call options on any
currency in order to realize greater income than would be realized on portfolio
securities transactions alone. However, in writing covered call options for
additional income, an Underlying Fund may forego the opportunity to profit from
an increase in the market value of the underlying currency. Also, when writing
put options, an Underlying Fund accepts, in return for the option premium, the
risk that it may be required to purchase the underlying currency at a price in
excess of the currency's market value at the time of purchase.

      Special Risks Associated With Options on Currency. An exchange traded
option position may be closed out only on an options exchange which provides a
secondary market for an option of the same series. There is no assurance that a
liquid secondary market on an exchange will exist for any particular option, or
at any particular time. In such event, it might not be possible to effect
closing transactions in particular options, with the result that an Underlying
Fund would have to exercise its options in order to realize any profit and would
incur transaction costs upon the sale of underlying securities pursuant to the
exercise of put options. If an Underlying Fund as a covered call option writer
is unable to effect a closing purchase transaction in a secondary market, it may
not be able to sell the underlying currency (or security quoted or denominated
in that currency) until the option expires or it delivers the underlying
currency upon exercise.

      There is no assurance that higher than anticipated trading activity or
other unforeseen events might not, at times, render certain of the facilities of
the Options Clearing Corporation inadequate, and thereby result in the
institution by an exchange of special procedures which may interfere with the
timely execution of customers' orders.

      An Underlying Fund may purchase and write over-the-counter options to the
extent consistent with its limitation on investments in illiquid securities.
Trading in over-the-counter options is subject to the risk that the other party
will be unable or unwilling to close out options purchased or written by an
Underlying Fund.


                                      B-50
<PAGE>
 
      The amount of the premiums which an Underlying Fund may pay or receive may
be adversely affected as new or existing institutions, including other
investment companies, engage in or increase their option purchasing and writing
activities.

Mortgage Dollar Rolls

      Certain of the Underlying Funds may enter into mortgage "dollar rolls" in
which an Underlying Fund sells securities for delivery in the current month and
simultaneously contracts with the same counterparty to repurchase similar (same
type, coupon and maturity), but not identical securities on a specified future
date. During the roll period, an Underlying Fund loses the right to receive
principal and interest paid on the securities sold. However, an Underlying Fund
would benefit to the extent of any difference between the price received for the
securities sold and the lower forward price for the future purchase (often
referred to as the "drop") or fee income plus the interest earned on the cash
proceeds of the securities sold until the settlement date of the forward
purchase. Unless such benefits exceed the income, capital appreciation and gain
or loss due to mortgage prepayments that would have been realized on the
securities sold as part of the mortgage dollar roll, the use of this technique
will diminish the investment performance of an Underlying Fund compared with
what such performance would have been without the use of mortgage dollar rolls.
All cash proceeds will be invested in instruments that are permissible
investments for the applicable Fund. An Underlying Fund segregates until the
settlement date cash or liquid assets, as permitted by applicable law, in an
amount equal to its forward purchase price.

      For financial reporting and tax purposes, the Underlying Funds treat
mortgage dollar rolls as two separate transactions; one involving the purchase
of a security and a separate transaction involving a sale. The Underlying Funds
do not currently intend to enter into mortgage dollar rolls that are accounted
for as a financing.

      Mortgage dollar rolls involve certain risks including the following: if
the broker-dealer to whom an Underlying Fund sells the security becomes
insolvent, an Underlying Fund's right to purchase or repurchase the
mortgage-related securities subject to the mortgage dollar roll may be
restricted and the instrument which an Underlying Fund is required to repurchase
may be worth less than an instrument which an Underlying Fund originally held.
Successful use of mortgage dollar rolls will depend upon the ability of an
Underlying Fund's investment adviser to manage an Underlying Fund's interest
rate and mortgage prepayments exposure. For these reasons, there is no assurance
that mortgage dollar rolls can be successfully employed.

Convertible Securities

      Convertible securities include corporate notes or preferred stock but are
ordinarily long-term debt obligations of the issuer convertible at a stated
exchange rate into common stock of the issuer. As with all debt securities, the
market value of convertible securities tends to decline as interest rates
increase and, conversely, to increase as interest rates decline. Convertible
securities generally offer lower interest or dividend yields than
non-convertible securities of similar quality. However, when the market price of
the common stock underlying a convertible security exceeds the conversion price,
the price of the convertible security tends to reflect the value of the
underlying common stock. As the market price of the underlying common stock
declines, the convertible security tends to trade increasingly on a yield basis,
and thus may not depreciate to the same extent as the underlying common stock.
Convertible securities rank senior to common stocks in an issuer's capital
structure and consequently entail less risk than the issuer's common stock.

Currency Swaps, Mortgage Swaps, Credit Swaps, Index Swaps and Interest Rate
Swaps, Caps, Floors and Collars

      Certain Underlying Funds may enter into currency swaps for both hedging
purposes and to seek to increase total return. In addition, certain of the
Underlying Fixed-Income Funds and Real Estate Securities Fund may enter into
mortgage, credit, index and interest rate swaps and other interest rate swap
arrangements such as rate caps, floors and collars, for hedging purposes or to
seek to increase total return. Currency swaps involve the exchange by an
Underlying Fund with another party of their respective rights to make or receive
payments in specified currencies. Interest rate swaps involve the exchange by an
Underlying Fund with another party of their respective commitments to pay or
receive interest, such as an exchange of fixed rate payments for floating rate
payments. Mortgage swaps are similar to interest rate swaps in that they
represent commitments to pay and receive interest. The notional principal
amount, however, is tied to a reference pool or pools of mortgages. Index swaps
involve the exchange by an Underlying Fund with another party of the respective
amounts payable with respect to a notional principal amount at interest rates
equal to two specified indices. The purchase of an interest rate cap entitles
the purchaser, to the extent that a specified index exceeds a predetermined
interest rate, to receive payment of interest on a notional principal amount
from the party selling such interest rate cap. Credit swaps involve the receipt
of floating or fixed rate payments in exchange for assuming potential credit
losses of an underlying security. Credit swaps give one party to a transaction
the right to dispose of or acquire an asset (or group of assets), or the right
to receive or make a payment from the other party, upon the occurrence of
specified credit events. The purchase of an interest rate floor entitles the
purchaser, to the extent that a specified index falls below a predetermined
interest rate, to receive payments of interest on a notional principal amount
from the party selling the interest rate floor. An interest rate collar is the
combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates. Since interest rate, mortgage and
currency swaps and interest rate caps, floors and collars are individually
negotiated, each Fund expects to achieve an acceptable degree of correlation
between its portfolio investments and its swap, cap, floor and collar positions.

      An Underlying Fund will enter into interest rate mortgage and index swaps
only on a net basis, which means that the two payment streams are netted out,
with the Underlying Fund receiving or paying, as the case may be, only the net
amount of the two payments. Interest rate, index and mortgage swaps do not
involve the delivery of securities, other underlying assets or principal.
Accordingly, the risk of loss with respect to interest rate, index and mortgage
swaps is limited to the net amount of interest payments that the Underlying Fund
is contractually obligated to make. If the other party to an interest rate,
index or mortgage swap defaults, the Underlying Fund's risk of loss consists of
the net amount of interest payments that the Underlying Fund is contractually
entitled to receive, if any. In contrast, currency swaps usually involve the
delivery of the entire principal amount of one designated currency in exchange
for the other designated currency. Therefore, the entire principal value of a
currency swap is subject to the risk that the other party to the swap will
default on its contractual delivery obligations. To the extent that an
Underlying Fund's potential exposure in a transaction involving a swap or an
interest rate floor, cap or collar is covered by the segregation of cash or
liquid assets or otherwise, the Underlying Funds and their investment advisers
believe that transactions do not constitute senior securities under the Act and,
accordingly, will not treat them as being subject to an Underlying Fund's
borrowing restrictions.

      An Underlying Equity Fund will not enter into swap transactions unless the
unsecured commercial paper, senior debt or claims paying ability of the other
party thereto is considered to be investment grade by its investment adviser.
The Underlying Fixed-Income Funds will not enter into any mortgage, interest
rate, credit or swap transactions unless the unsecured commercial paper, senior
debt or claims-paying ability of 


                                      B-52
<PAGE>
 
the other party is rated either A or A-1 or better by Standard & Poor's or A or
P-1 or better by Moody's or, if unrated by such rating agencies, determined to
be of comparable quality by the applicable investment adviser. The Core Fixed
Income, Global Income and High Yield Funds will not enter into any currency swap
transactions unless the unsecured commercial paper, senior debt or claims-paying
ability of the other party thereto is rated investment grade by Standard &
Poor's or Moody's or their equivalent ratings or, if unrated by such rating
agencies, determined to be of comparable quality by the applicable investment
adviser. If there is a default by the other party to such a transaction, an
Underlying Fund will have contractual remedies pursuant to the agreements
related to the transaction. The swap market has grown substantially in recent
years with a large number of banks and investment banking firms acting both as
principals and as agents utilizing standardized swap documentation. As a result,
the swap market has become relatively liquid in comparison with the markets for
other similar instruments which are traded in the interbank market. The
investment advisers, under the supervision of the Board of Trustees, are
responsible for determining and monitoring the liquidity of the Underlying
Funds' transactions in swaps, caps, floors and collars.

      The use of interest rate, mortgage, credit, index and currency swaps, as
well as interest rate caps, floors and collars, is a highly specialized activity
which involves investment techniques and risks different from those associated
with ordinary portfolio securities transactions. If an Underlying Fund's
investment adviser is incorrect in its forecasts of market values, interest
rates and currency exchange rates, the investment performance of an Underlying
Fund would be less favorable than it would have been if this investment
technique were not used.

Equity Swaps

      Each Underlying Equity Fund may enter into equity swap contracts to invest
in a market without owning or taking physical custody of securities in
circumstances in which direct investment is restricted for legal reasons or is
otherwise impracticable. Equity swaps may also be used for hedging purposes or
to seek to increase total return. The counterparty to an equity swap contract
will typically be a bank, investment banking firm or broker/dealer. Equity swaps
may be structured in different ways. For example, a counterparty may agree to
pay the Underlying Fund the amount, if any, by which the notional amount of the
equity swap contract would have increased in value had it been invested in the
particular stocks (or an index of stocks), plus the dividends that would have
been received on those stocks. In those cases, the Underlying Fund may agree to
pay to the counterparty a floating rate of interest on the notional amount of
the equity swap contract plus the amount, if any, by which that notional amount
would have decreased in value had it been invested in such stocks. Therefore,
the return to the Underlying Fund on the equity swap contract should be the gain
or loss on the notional amount plus dividends on the stocks less the interest
paid by the Underlying Fund on the notional amount. In other cases, the
conterparty and the Underlying Fund may each agree to pay the other the
difference between the relative investment performances that would have been
achieved if the notional amount of the equity swap contract had been invested in
different stocks (or indices of stocks).

      An Underlying Fund will enter into equity swaps only on a net basis, which
means that the two payment streams are netted out, with the Underlying Fund
receiving or paying, as the case may be, only the net amount of the two
payments. Payments may be made at the conclusion of an equity swap contract or
periodically during its term. Equity swaps do not involve the delivery of
securities or other underlying assets. Accordingly, the risk of loss with
respect to equity swaps is limited to the net amount of payments that an
Underlying Fund is contractually obligated to make. If the other party to an
equity swap defaults, an Underlying Fund's risk of loss consists of the net
amount of payments that such Fund is contractually entitled to receive, if any.
Inasmuch as these transactions are entered into for hedging purposes or are

offset by segregated cash or liquid assets to cover the Underlying Funds'
potential exposure, the Underlying Funds and their investment advisers believe
that transactions do not constitute senior securities under the Act and,
accordingly, will not treat them as being subject to an Underlying Funds
borrowing restrictions.

      An Underlying Equity Fund will not enter into equity swap transactions
unless the unsecured commercial paper, senior debt or claims paying ability of
the other party thereto is considered to be investment grade by the investment
adviser.

Real Estate Investment Trusts

      The Underlying Equity Funds may invest in shares of REITs. REITs are
pooled investment vehicles which invest primarily in income producing real
estate or real estate related loans or interest. REITs are generally classified
as equity REITs, mortgage REITs or a combination of equity and mortgage REITs.
Equity REITs invest the majority of their assets directly in real property and
derive income primarily from the collection of rents. Equity REITs can also
realize capital gains by selling properties that have appreciated in value.
Mortgage REITs invest the majority of their assets in real estate mortgages and
derive income from the collection of interest payments. Like regulated
investment companies such as the Underlying Funds, REITs are not taxed on income
distributed to shareholders provided they comply with certain requirements under
the Code. An Underlying Fund will indirectly bear its proportionate share of any
expenses paid by REITs in which it invests in addition to the expenses paid by
an Underlying Fund.

      Investing in REITs involves certain unique risks. Equity REITs may be
affected by changes in the value of the underlying property owned by such REITs,
while mortgage REITs may be affected by the quality of any credit extended.
REITs are dependent upon management skills, are not diversified (except to the
extent the Code requires), and are subject to the risks of financing projects.
REITs are subject to heavy cash flow dependency, default by borrowers,
self-liquidation, and the possibilities of failing to qualify for the exemption
from tax for distributed income under the Code and failing to maintain their
exemptions from the Act. REITs (especially mortgage REITs) are also subject to
interest rate risks.

Lending of Portfolio Securities

      Each Underlying Fund may lend portfolio securities. Under present
regulatory policies, such loans may be made to institutions such as brokers or
dealers and would be required to be secured continuously by collateral in cash,
cash equivalents or U.S. Government securities maintained on a current basis at
an amount at least equal to the market value of the securities loaned. An
Underlying Fund would be required to have the right to call a loan and obtain
the securities loaned at any time on five days' notice. For the duration of a
loan, an Underlying Fund would continue to receive the equivalent of the
interest or dividends paid by the issuer on the securities loaned and would also
receive compensation from investment of the collateral. An Underlying Fund would
not have the right to vote any securities having voting rights during the
existence of the loan, but an Underlying Fund would call the loan in
anticipation of an important vote to be taken among holders of the securities or
the giving or withholding of their consent on a material matter affecting the
investment. As with other extensions of credit there are risks of delay in
recovering, or even loss of rights in, the collateral should the borrower of the
securities fail financially. However, the loans would be made only to firms
deemed by an Underlying Fund's investment adviser to be of good standing, and
when, in the judgment of an Underlying Fund's investment adviser, the
consideration which can be earned currently from securities loans of this type
justifies the attendant risk. If an investment adviser determines to make
securities loans, it is intended that the value of the securities loaned would
not exceed one-third of the value of the total assets of an Underlying Fund
(including the loan collateral).

When-Issued Securities and Forward Commitments

      Each Underlying Fund may purchase securities on a when-issued basis or
purchase or sell securities on a forward commitment basis. These transactions
involve a commitment by an Underlying Fund to purchase or sell securities at a
future date. The price of the underlying securities (usually expressed in terms
of yield) and the date when the securities will be delivered and paid for (the
settlement date) are fixed at the time the transaction is negotiated.
When-issued purchases and forward commitment transactions are negotiated
directly with the other party, and such commitments are not traded on exchanges.
An Underlying Fund will purchase securities on a when-issued basis or purchase
or sell securities on a forward commitment basis only with the intention of
completing the transaction and actually purchasing or selling the securities. If
deemed advisable as a matter of investment strategy, however, an Underlying Fund
may dispose of or negotiate a commitment after entering into it. The Underlying
Funds may also realize a capital gain or loss in connection with these
transactions. For purposes of determining an Underlying Fund's duration, the
maturity of when-issued or forward commitment securities will be calculated from
the commitment date. An Underlying Fund is required to segregate until three
days prior to the settlement date, cash and liquid assets in an amount
sufficient to meet the purchase price. Alternatively, an Underlying Fund may
enter into offsetting contracts for the forward sale of other securities that it
owns. Securities purchased or sold on a when-issued or forward commitment basis
involve a risk of loss if the value of the security to be purchased declines
prior to the settlement date or if the value of the security to be sold
increases prior to the settlement date.

Investment in Unseasoned Companies

      Each Underlying Fund may invest a portion of its net assets in companies
(including predecessors) which have operated less than three years, except that
this limitation does not apply to debt securities which have been rated
investment grade or better by at least one NRSRO. The securities of such
companies may have limited liquidity, which can result in their being priced
higher or lower than might otherwise be the case. In addition, investments in
unseasoned companies are more speculative and entail greater risk than do
investments in companies with an established operating record.

Other Investment Companies

      Each of the Underlying Funds may make limited investments in the
securities of other investment companies including, pursuant to an exemptive
order obtained from the SEC, money market funds for which the Adviser or any of
its affiliates serves as investment adviser. An Underlying Fund will indirectly
bear its proportionate share of any management fees and other expenses paid by
investment companies in which it invests in addition to the advisory and
administration fees paid by the Underlying Fund. However, to the extent that the
Underlying Fund invests in a money market fund for which the Adviser or any of
its affiliates acts as adviser, the advisory and administration fees payable by
the Underlying Fund to the investment adviser or its affiliates will be reduced
by an amount equal to the Underlying Fund's proportionate share of the advisory
and administration fees paid by such money market fund to the investment adviser
or its affiliates.

      Each Underlying Equity Fund may also invest in SPDRs. SPDRs are interests
in a unit investment trust ("UIT") that may be obtained from the UIT or
purchased in the secondary market (SPDRs are listed on the American Stock
Exchange). The UIT will issue SPDRs in aggregations known as "Creation Units" in
exchange for a "Portfolio Deposit" consisting of (a) a portfolio of securities
substantially similar to the component securities ("Index Securities") of the
Standard & Poor's 500 Composite Stock Price Index (the 


                                      B-55
<PAGE>
 
"S&P Index"), (b) a cash payment equal to a pro rata portion of the dividends
accrued on the UIT's portfolio securities since the last dividend payment by the
UIT, net of expenses and liabilities, and (c) a cash payment or credit
("Balancing Amount") designed to equalize the net asset value of the S&P Index
and the net asset value of a Portfolio Deposit.

      SPDRs are not individually redeemable, except upon termination of the UIT.
To redeem, the Underlying Fund must accumulate enough SPDRs to reconstitute a
Creation Unit. The liquidity of small holdings of SPDRs, therefore, will depend
upon the existence of a secondary market. Upon redemption of a Creation Unit,
the Underlying Fund will receive Index Securities and cash identical to the
Portfolio Deposit required of an investor wishing to purchase a Creation Unit
that day.

      The price of SPDRs is derived from and based upon the securities held by
the UIT. Accordingly, the level of risk involved in the purchase or sale of a
SPDR is similar to the risk involved in the purchase or sale of traditional
common stock, with the exception that the pricing mechanism for SPDRs is based
on a basket of stocks. Disruptions in the markets for the securities underlying
SPDRs purchased or sold by the Underlying Funds could result in losses on SPDRs.

      Certain Underlying Funds may also purchase shares of investment companies
investing primarily in foreign securities, including "country funds." Country
funds have portfolios consisting primarily of securities of issuers located in
one foreign country or region. Certain Underlying Funds may also invest in World
Equity Benchmark Shares ("WEBS") and similar securities that invest in
securities included in foreign securities indices.

Repurchase Agreements

      Each Underlying Fund may enter into repurchase agreements with selected
broker-dealers, banks and other financial institutions. A repurchase agreement
is an arrangement under which an Underlying Fund purchases securities and the
seller agrees to repurchase the securities within a particular time and at a
specified price. Custody of the securities is maintained by an Underlying Fund's
custodian. The repurchase price may be higher than the purchase price, the
difference being income to an Underlying Fund, or the purchase and repurchase
prices may be the same, with interest at a stated rate due to an Underlying Fund
together with the repurchase price on repurchase. In either case, the income to
an Underlying Fund is unrelated to the interest rate on the security subject to
the repurchase agreement.

      For purposes of the Act and generally for tax purposes, a repurchase
agreement is deemed to be a loan from an Underlying Fund to the seller of the
security. For other purposes, it is not always clear whether a court would
consider the security purchased by an Underlying Fund subject to a repurchase
agreement as being owned by an Underlying Fund or as being collateral for a loan
by an Underlying Fund to the seller. In the event of commencement of bankruptcy
or insolvency proceedings with respect to the seller of the security before
repurchase of the security under a repurchase agreement, an Underlying Fund may
encounter delay and incur costs before being able to sell the security. Such a
delay may involve loss of interest or a decline in price of the security. If the
court characterizes the transaction as a loan and an Underlying Fund has not
perfected a security interest in the security, an Underlying Fund may be
required to return the security to the seller's estate and be treated as an
unsecured creditor of the seller. As an unsecured creditor, an Underlying Fund
would be at risk of losing some or all of the principal and interest involved in
the transaction.

      The Underlying Fund's investment adviser seeks to minimize the risk of
loss from repurchase agreements by analyzing the creditworthiness of the
obligor, in this case the seller of the security. Apart


                                      B-56
<PAGE>
 
from the risk of bankruptcy or insolvency proceedings, there is also the risk
that the seller may fail to repurchase the security. However, if the market
value of the security subject to the repurchase agreement becomes less than the
repurchase price (including accrued interest), an Underlying Fund will direct
the seller of the security to deliver additional securities so that the market
value of all securities subject to the repurchase agreement equals or exceeds
the repurchase price. Certain repurchase agreements which provide for settlement
in more than seven days can be liquidated before the nominal fixed term on seven
days or less notice. Such repurchase agreements will be regarded as liquid
instruments.

      In addition, an Underlying Fund, together with other registered investment
companies having advisory agreements with the Adviser or its affiliates, may
transfer uninvested cash balances into a single joint account, the daily
aggregate balance of which will be invested in one or more repurchase
agreements.

Reverse Repurchase Agreements

      Certain Underlying Funds may borrow money by entering into transactions
called reverse repurchase agreements. Under these arrangements, a Fund will sell
portfolio securities to dealers in U.S. Government Securities or members of the
Federal Reserve System, with an agreement to repurchase the security on an
agreed date, price and interest payment. The Core Fixed Income, Global Income
and High Yield Funds may also enter into reverse repurchase agreements involving
certain foreign government securities. Reverse repurchase agreements involve the
possible risk that the value of portfolio securities a Fund relinquishes may
decline below the price a Fund must pay when the transaction closes. Borrowings
may magnify the potential for gain or loss on amounts invested resulting in an
increase in the speculative character of a Fund's outstanding shares.

      When a Fund enters into a reverse repurchase agreement, it segregates cash
or liquid assets that have a value equal to or greater than the repurchase
price. The account is then continuously monitored by its investment adviser to
make sure that an appropriate value is maintained. Reverse repurchase agreements
are considered to be borrowings under the Act.

Restricted and Illiquid Securities

      The Underlying Funds may not invest more than 15% (10% in the case of
Financial Square Prime Obligations Fund) of their net assets in illiquid
investments, which include securities (both foreign and domestic) that are not
readily marketable, certain SMBS, certain municipal leases and participation
interests, certain over-the-counter options, repurchase agreements and time
deposits with a notice or demand period of more than seven days, and certain
restricted securities, unless it is determined, based upon a continuing review
of the trading markets for the specific instrument, that such instrument is
liquid. The Trustees have adopted guidelines under which the Underlying Funds'
investment advisers determine and monitor the liquidity of the Underlying Funds'
portfolio securities. This investment practice could have the effect of
increasing the level of illiquidity in an Underlying Fund to the extent that
qualified institutional buyers become for a time uninterested in purchasing
these instruments.

      The purchase price and subsequent valuation of restricted securities may
reflect a discount from the price at which such securities trade when they are
not restricted, since the restriction may make them less liquid. The amount of
the discount from the prevailing market price is expected to vary depending upon
the type of security, the character of the issuer, the party who will bear the
expenses of registering the restricted securities and prevailing supply and
demand conditions.

<PAGE>
 
Portfolio Turnover

      Each Underlying Fund may engage in active short-term trading to benefit
from yield disparities among different issues of securities or among the markets
for fixed-income securities, or for other reasons. It is anticipated that the
portfolio turnover rate of each Fund will vary from year to year.

                             INVESTMENT RESTRICTIONS

      The following investment restrictions have been adopted by the Trust as
fundamental policies that cannot be changed without the affirmative vote of the
holders of a majority (as defined in the Act) of the outstanding voting
securities of the affected Portfolio. The investment objective of each Portfolio
and all other investment policies or practices of each Portfolio are considered
by the Trust not to be fundamental and accordingly may be changed without
shareholder approval. For purposes of the Act, "majority" means the lesser of
(a) 67% or more of the shares of the Trust or a Portfolio present at a meeting,
if the holders of more than 50% of the outstanding shares of the Trust or a
Portfolio are present or represented by proxy, or (b) more than 50% of the
shares of the Trust or a Portfolio. For purposes of the following limitations,
any limitation which involves a maximum percentage shall not be considered
violated unless an excess over the percentage occurs immediately after, and is
caused by, an acquisition or encumbrance of securities or assets of, or
borrowings by, a Portfolio. With respect to the Portfolios' fundamental
investment restriction no. 3, asset coverage of at least 300% (as defined in the
Act), inclusive of any amounts borrowed, must be maintained at all times.

      As a matter of fundamental policy, a Portfolio may not:

            (1)   make any investment inconsistent with the Portfolio's
                  classification as a diversified company under the Act;

            (2)   invest 25% or more of its total assets in the securities of
                  one or more issuers conducting their principal business
                  activities in the same industry (excluding investment
                  companies and the U.S. Government or any of its agencies or
                  instrumentalities). (For the purposes of this restriction,
                  state and municipal governments and their agencies,
                  authorities and instrumentalities are not deemed to be
                  industries; telephone companies are considered to be a
                  separate industry from water, gas or electric utilities;
                  personal credit finance companies and business credit finance
                  companies are deemed to be separate industries; and
                  wholly-owned finance companies are considered to be in the
                  industry of their parents if their activities are primarily
                  related to financing the activities of their parents.) This
                  restriction does not apply to investments in municipal
                  securities which have been pre-refunded by the use of
                  obligations of the U.S. government or any of its agencies or
                  instrumentalities;

            (3)   borrow money, except (a) the Portfolio may borrow from banks
                  (as defined in the Act) or through reverse repurchase
                  agreements in amounts up to 33-1/3% of its total assets
                  (including the amount borrowed), (b) the Portfolio may, to the
                  extent permitted by applicable law, borrow up to an additional
                  5% of its total assets for temporary purposes, (c) the
                  Portfolio may obtain such short-term credits as may be
                  necessary for the clearance of purchases and sales of
                  portfolio securities, (d) the Portfolio may purchase
                  securities on margin to the extent permitted by applicable


                                      B-58
<PAGE>
 
                  law and (e) the Portfolio may engage transactions in mortgage
                  dollar rolls which are accounted for as financings;

            (4)   make loans, except through (a) the purchase of debt
                  obligations in accordance with the Portfolio's investment
                  objective and policies, (b) repurchase agreements with banks,
                  brokers, dealers and other financial institutions and (c)
                  loans of securities as permitted by applicable law;

            (5)   underwrite securities issued by others, except to the extent
                  that the sale of portfolio securities by the Portfolio may be
                  deemed to be an underwriting;

            (6)   purchase, hold or deal in real estate, although a Portfolio
                  may purchase and sell securities that are secured by real
                  estate or interests therein, securities of real estate
                  investment trusts and mortgage-related securities and may hold
                  and sell real estate acquired by a Portfolio as a result of
                  the ownership of securities;

            (7)   invest in commodities or commodity contracts, except that the
                  Portfolio may invest in currency and financial instruments and
                  contracts that are commodities or commodity contracts;

            (8)   issue senior securities to the extent such issuance would
                  violate applicable law.

      Notwithstanding any other fundamental investment restriction or policy,
each Portfolio may invest some or all of its assets in a single open-end
investment company or series thereof with substantially the same investment
objective, restrictions and policies as the Portfolio.

      In addition to the fundamental policies mentioned above, the Trustees have
adopted the following non-fundamental policies which can be changed or amended
by action of the Trustees without approval of shareholders.

      A Portfolio may not:

            (a)   Invest in companies for the purpose of exercising control or
                  management (but this does not prevent a Portfolio from
                  purchasing a controlling interest in one or more of the
                  Underlying Funds consistent with its investment objective and
                  policies).

            (b)   Invest more than 15% of the Portfolio's net assets in illiquid
                  investments, including repurchase agreements with a notice or
                  demand period of more than seven days, securities which are
                  not readily marketable and restricted securities not eligible
                  for resale pursuant to Rule 144A under the 1933 Act.

            (c)   Purchase additional securities if the Portfolio's borrowings
                  (excluding covered mortgage dollar rolls) exceed 5% of its net
                  assets.

            (d)   Make short sales of securities, except short sales against the
                  box.

      The Underlying Funds in which the Portfolios may invest have adopted
certain investment restrictions which may be more or less restrictive than those
listed above, thereby allowing a Portfolio to participate in certain investment
strategies indirectly that are prohibited under the fundamental and non-


                                      B-59
<PAGE>
 
fundamental investment restrictions and policies listed above. The investment
restrictions of these Underlying Funds are set forth in their respective
Additional Statements.

                                   MANAGEMENT

Management Services

      As stated in the Portfolios' Prospectus, Goldman Sachs Asset Management
serves as Adviser to the Portfolios and, except as noted, to each Underlying
Fund. Goldman Sachs Funds Management, L.P. serves as investment adviser to the
CORE U.S. Equity, Capital Growth, Adjustable Rate Government and Short Duration
Government Funds. Goldman Sachs Asset Management International ("GSAMI") serves
as investment adviser to the International Equity, European Equity, Japanese
Equity, International Small Cap, Emerging Markets Equity, Asia Growth and Global
Income Funds. As a company with unlimited liability under the laws of England,
GSAMI is regulated by the Investment Management Regulatory Organization Limited,
a United Kingdom self-regulatory organization, in the conduct of its investment
advisory business. See "Service Providers" in the Portfolios' Prospectus for a
description of the Adviser's duties to the Portfolios. Goldman Sachs has agreed
to permit the Funds to use the name "Goldman Sachs" or a derivative thereof as
part of each Fund's name for as long as a Fund's Management Agreement is in
effect.

      The Goldman Sachs Group, L.P., which controls the Portfolios' Adviser and
the investment adviser of each Underlying Fund, announced that it will pursue an
initial public offering of the firm in the late spring or early summer of 1999.
Simultaneously with the offering, the Goldman Sachs Group, L.P. will merge into
The Goldman Sachs Group, Inc.

      Founded in 1869, Goldman Sachs is among the oldest and largest investment
banking firms in the United States. Goldman Sachs is a leader in developing
portfolio strategies and in many fields of investing and financing,
participating in financial markets worldwide and serving individuals,
institutions, corporations and governments. Goldman Sachs also is among the
principal market sources for current and thorough information on companies,
industrial sectors, markets, economies and currencies, and trades and makes
markets in a wide range of equity and debt securities 24-hours a day. The firm
is headquartered in New York and has offices throughout the United States and in
Beijing, Brazil, Frankfurt, George Town, Hong Kong, London, Madrid, Mexico City,
Milan, Montreal, Osaka, Paris, Sao Paulo, Seoul, Shanghai, Singapore, Sydney,
Taipei, Tokyo, Toronto, Vancouver and Zurich. It has trading professionals
throughout the United States, as well as in London, Tokyo, Hong Kong and
Singapore. The active participation of Goldman Sachs in the world's financial
markets enhances its ability to identify attractive investments.

      The Underlying Funds' investment advisers are able to draw on the
substantial research and market expertise of Goldman Sachs whose investment
research effort is one of the largest in the industry. The Goldman Sachs Global
Investment Research Department covers approximately 2,200 companies, including
approximately 1,000 U.S. corporations in 60 industries. The in-depth information
and analyses generated by Goldman Sachs' research analysts are available to the
Investment Advisers.

      For more than a decade, Goldman Sachs has been among the top-ranked firms
in Institutional Investor's annual "All-America Research Team" survey. In
addition, many of Goldman Sachs' economists, securities analysts, portfolio
strategists and credit analysts have consistently been highly ranked in
respected industry surveys conducted in the United States and abroad. Goldman
Sachs is also 


                                      B-69
<PAGE>
 
among the leading investment firms using quantitative analytics (now used by a
growing number of investors) to structure and evaluate portfolios.

      In managing the Underlying Funds, the Underlying Funds' investment
advisers have access to Goldman Sachs' economics research. The Economics
Research Department, based in London, conducts economic, financial and currency
markets research which analyzes economic trends and interest and exchange rate
movement worldwide. The Economics Research Department tracks factors such as
inflation and money supply figures, balance of trade figures, economic growth,
commodity prices, monetary and fiscal policies, and political events that can
influence interest rates and currency trends. The success of Goldman Sachs'
international research team has brought wide recognition to its members. The
team has earned top rankings in various external surveys such as Extel,
Institutional Investor, and Reuters. These rankings acknowledge the achievements
of the firm's economists, strategists and equity analysts.

      In structuring Adjustable Rate Government Fund's and Short Duration
Government Fund's respective securities portfolios, their investment adviser
will review the existing overall economic and mortgage market trends. The
investment adviser will then study yield spreads, the implied volatility and the
shape of the yield curve. The investment adviser will then apply this analysis
to a list of eligible securities that meet the respective Fund's investment
guidelines. With respect to Adjustable Rate Government Fund, this analysis is
used to plan a two-part portfolio, which will consist of a "core" portfolio of
ARMs and a "relative value" portfolio of other mortgage assets that can enhance
portfolio returns and lower risk (such as investments in CMO floating-rate
tranches and interest only SMBS).

      With respect to Adjustable Rate Government Fund, Short Duration Government
Fund, Government Income Fund, Core Fixed Income Fund and High Yield Fund, the
applicable investment advisers expect to utilize Goldman Sachs' sophisticated
option-adjusted analytics to help make strategic asset allocations within the
markets for U.S. government, Mortgage-Backed and other securities and to employ
this technology periodically to re-evaluate the Funds' investments as market
conditions change. Goldman Sachs has also developed a prepayment model designed
to estimate mortgage prepayments and cash flows under different interest rate
scenarios. Because a Mortgage-Backed Security incorporates the borrower's right
to prepay the mortgage, the investment advisers use a sophisticated
option-adjusted spread (OAS) model to measure expected returns. A security's OAS
is a function of the level and shape of the yield curve, volatility and the
particular investment adviser's expectation of how a change in interest rates
will affect prepayment levels. Since the OAS model assumes a relationship
between prepayments and interest rates, the investment advisers consider it a
better way to measure a security's expected return and absolute and relative
values than yield to maturity. In using OAS technology, the investment advisers
will first evaluate the absolute level of a security's OAS considering its
liquidity and its interest rate, volatility and prepayment sensitivity. The
investment advisers will then analyze its value relative to alternative
investments and to its own investments. The investment advisers will also
measure a security's interest rate risk by computing an option adjusted duration
(OAD). The investment advisers believe a security's OAD is a better measurement
of its price sensitivity than cash flow duration, which systematically misstates
portfolio duration. The investment advisers also evaluate returns for different
mortgage market sectors and evaluates the credit risk of individual securities.
This sophisticated technical analysis allows the investment advisers to develop
portfolio and trading strategies using Mortgage-Backed Securities that are
believed to be superior investments on a risk-adjusted basis and which provide
the flexibility to meet the respective Funds' duration targets and cash flow
pattern requirements.

      Because the OAS is adjusted for the differing characteristics of the
underlying securities, the OAS of different Mortgage-Backed Securities can be
compared directly as an indication of their relative value in the market. The
investment advisers also expect to use OAS-based pricing methods to calculate
projected 


                                      B-70
<PAGE>
 
security returns under different, discrete interest rate scenarios, and Goldman
Sachs' proprietary prepayment model to generate yield estimates under these
scenarios. The OAS, scenario returns, expected returns, and yields of securities
in the mortgage market can be combined and analyzed in an optimal risk-return
matching framework.

      The investment advisers will use OAS analytics to choose what they believe
is an appropriate portfolio of investments for an Underlying Fund from a
universe of eligible investments. In connection with initial portfolio
selections, in addition to using OAS analytics as an aid to meeting each Fund's
particular composition and performance targets, the investment advisers will
also take into account important market criteria like the available supply and
relative liquidity of various mortgage securities in structuring the portfolio.

      The Underlying Funds' investment advisers also expect to use OAS analytics
to evaluate the mortgage market on an ongoing basis. Changes in the relative
value of various Mortgage-Backed Securities could suggest tactical trading
opportunities for the Underlying Funds. The investment advisers will have access
to both current market analysis as well as historical information on the
relative value relationships among different Mortgage-Backed Securities. Current
market analysis and historical information is available in the Goldman Sachs
database for most actively traded Mortgage-Backed Securities.

      Goldman Sachs has agreed to provide the Underlying Funds' investment
advisers, on a non-exclusive basis, use of its mortgage prepayment model, OAS
model and any other proprietary services which it now has or may develop, to the
extent such services are made available to other similar customers. Use of these
services by the Underlying Funds' investment advisers with respect to an
Underlying Fund does not preclude Goldman Sachs from providing these services to
third parties or using such services as a basis for trading for its own account
or the account of others.

      The fixed-income research capabilities of Goldman Sachs available to the
Underlying Funds' investment advisers include the Goldman Sachs Fixed-Income
Research Department and the Credit Department. The Fixed-Income Research
Department monitors developments in U.S. and foreign fixed-income markets,
assesses the outlooks for various sectors of the markets and provides relative
value comparisons, as well as analyzes trading opportunities within and across
market sectors. The Fixed-Income Research Department is at the forefront in
developing and using computer-based tools for analyzing fixed-income securities
and markets, developing new fixed-income products and structuring portfolio
strategies for investment policy and tactical asset allocation decisions. The
Credit Department tracks specific governments, regions and industries and from
time to time may review the credit quality of an Underlying Fund's investments.

      In allocating assets among foreign countries and currencies for the
Underlying Funds which can invest in foreign securities, the Underlying Funds'
investment advisers will have access to the Global Asset Allocation Model. The
model is based on the observation that the prices of all financial assets,
including foreign currencies, will adjust until investors globally are
comfortable holding the pool of outstanding assets. Using the model, the
investment advisers will estimate the total returns from each currency sector
which are consistent with the average investor holding a portfolio equal to the
market capitalization of the financial assets among those currency sectors.
These estimated equilibrium returns are then combined with the expectations of
Goldman Sachs' research professionals to produce an optimal currency and asset
allocation for the level of risk suitable for an Underlying Fund given its
investment objectives and criteria.

      The management agreements for the Portfolios and the Underlying Funds
provide that the Adviser (and its affiliates) may render similar services to
others as long as the services provided by them thereunder are not impaired
thereby.

      The Portfolios' management agreement was most recently approved by the
Trustees, including a majority of the Trustees who are not parties to the
management agreement or "interested persons" (as such term is defined in the
Act) of any party thereto (the "non-interested Trustees"), on April 27, 1999.
These arrangements were approved by the sole shareholder of the Balanced
Strategy, Growth and Income Strategy, Growth Strategy and Aggressive Growth
Strategy Portfolios on January 1, 1998, and of the Conservative Strategy
Portfolio on February 3, 1999 by consent action to satisfy conditions imposed by
the SEC in connection with the registration of shares of the Portfolio. The
management agreement will remain in effect until June 30, 2000 and from year to
year thereafter provided such continuance is specifically approved at least
annually by (a) the vote of a majority of the outstanding voting securities of
such Portfolio or a majority of the Trustees, and (b) the vote of a majority of
the non-interested Trustees, cast in person at a meeting called for the purpose
of voting on such approval. The management agreement will terminate
automatically with respect to a Portfolio if assigned (as defined in the Act)
and is terminable at any time without penalty by the Trustees or by vote of a
majority of the outstanding voting securities of the affected Portfolio on 60
days' written notice to the Adviser and by the Adviser on 60 days' written
notice to the Trust.

      Under the management agreement, the Adviser also: (i) supervises all
non-advisory operations of each Portfolio; (ii) provides personnel to perform
such executive, administrative and clerical services as are reasonably necessary
to provide effective administration of each Portfolio; (iii) arranges for at
each Portfolio's expense (a) the preparation of all required tax returns, (b)
the preparation and submission of reports to existing shareholders, (c) the
periodic updating of prospectuses and statements of additional information and
(d) the preparation of reports to be filed with the SEC and other regulatory
authorities; (iv) maintains each Portfolio's records; and (v) provides office
space and all necessary office equipment and services.

      Pursuant to the management agreement, the Advisers are entitled to receive
the contractual fees listed below, payable monthly of such Portfolio's average
daily net assets.

      Activities of Goldman Sachs and Its Affiliates and Other Accounts Managed
by Goldman Sachs. The involvement of the Adviser and Goldman Sachs and their
affiliates in the management of, or their interest in, other accounts and other
activities of Goldman Sachs may present conflicts of interest with respect to
the Portfolios and the Underlying Funds or impede their investment activities.

      Goldman Sachs and its affiliates, including, without limitation, the
Adviser and its advisory affiliates, have proprietary interests in, and may
manage or advise with respect to, accounts or funds (including separate accounts
and other funds and collective investment vehicles) which have investment
objectives similar to those of the Portfolios and the Underlying Funds and/or
which engage in transactions in the same types of securities, currencies and
instruments. Goldman Sachs and its affiliates are major participants in the
global currency, equities, swap and fixed-income markets, in each case both on a
proprietary basis and for the accounts of customers. As such, Goldman Sachs and
its affiliates are actively engaged in transactions in the same securities,
currencies and instruments in which the Underlying Funds invest. Such activities
could affect the prices and availability of the securities, currencies and
instruments in which the Underlying Funds invest, which could have an adverse
impact on each Fund's (and, consequently, each Portfolio's) performance. Such
transactions, particularly in respect of proprietary accounts or customer
accounts other than those included in the Adviser's and its advisory affiliates'
asset management activities, will be executed independently of the Underlying
Funds' transactions and thus at prices or rates that may be more or less
favorable. When the Adviser and its advisory affiliates seek to purchase or sell
the same assets for their managed accounts, including the Underlying Funds, the
assets actually purchased or sold may be allocated among the accounts on a basis
determined in its good faith discretion to be equitable. In some cases, this
system may adversely affect the size or the price of the assets purchased or
sold for the Underlying Funds.

      From time to time, the Underlying Funds' activities may be restricted
because of regulatory restrictions applicable to Goldman Sachs and its
affiliates, and/or their internal policies designed to comply with such
restrictions. As a result, there may be periods, for example, when the Adviser
and/or its affiliates will not initiate or recommend certain types of
transactions in certain securities or instruments with respect to which the
Adviser and/or its affiliates are performing services or when position limits
have been reached.

      In connection with their management of the Underlying Funds, the
Underlying Funds' investment advisers may have access to certain fundamental
analysis and proprietary technical models developed by Goldman Sachs and other
affiliates. The investment advisers will not be under any obligation, however,
to effect transactions on behalf of the Underlying Funds in accordance with such
analysis and models. In addition, neither Goldman Sachs nor any of its
affiliates will have any obligation to make available any information regarding
their proprietary activities or strategies, or the activities or strategies used
for other accounts managed by them, for the benefit of the management of the
Underlying Funds and it is not anticipated that the investment advisers will
have access to such information for the purpose of managing the Underlying
Funds. The proprietary activities or portfolio strategies of Goldman Sachs and
its affiliates or the activities or strategies used for accounts managed by them
or other customer accounts could conflict with the transactions and strategies
employed by the investment advisers in managing the Underlying Funds.

      The results of each Underlying Fund's investment activities may differ
significantly from the results achieved by their investment advisers and
affiliates for their proprietary accounts or accounts (including investment
companies or collective investment vehicles) managed or advised by them. It is
possible that Goldman Sachs and its affiliates and such other accounts will
achieve investment results which are substantially more or less favorable than
the results achieved by an Underlying Fund. Moreover, it is possible that an
Underlying Fund will sustain losses during periods in which Goldman Sachs and
its affiliates achieve significant profits on their trading for proprietary or
other accounts. The opposite result is also possible.

      The investment activities of Goldman Sachs and its affiliates for their
proprietary accounts and accounts under their management may also limit the
investment opportunities for the Underlying Funds in certain emerging markets in
which limitations are imposed upon the aggregate amount of investment, in the
aggregate or individual issuers, by affiliated foreign investors.

      An investment policy committee which may include partners of Goldman Sachs
and its affiliates may develop general policies regarding an Underlying Fund's
activities but will not be involved in the day-to-day management of such Fund.
In such instances, those individuals may, as a result, obtain information
regarding the Underlying Fund's proposed investment activities which is not
generally available to the public. In addition, by virtue of their affiliation
with Goldman Sachs, any such member of an investment policy committee will have
direct or indirect interests in the activities of Goldman Sachs and its
affiliates in securities currencies and investments similar to those in which
the Underlying Fund invests.

      In addition, certain principals and certain of the employees of the
Underlying Funds' investment advisers are also principals or employees of
Goldman Sachs or their affiliated entities. As a result, the performance by
these principals and employees of their obligations to such other entities may
be a consideration of which investors in the Portfolios should be aware.

      The Underlying Funds' investment advisers may enter into transactions and
invest in currencies or instruments on behalf of an Underlying Fund in which
customers of Goldman Sachs serve as the counterparty, principal or issuer. In
such cases, such party's interests in the transaction will be adverse to the
interests of an Underlying Fund, and such party may have no incentive to assure
that the Underlying Funds obtain the best possible prices or terms in connection
with the transactions. Goldman Sachs and its affiliates may also create, write
or issue derivative instruments for customers of Goldman Sachs or its
affiliates, the underlying securities, currencies or instruments of which may be
those in which an Underlying Fund invests or which may be based on the
performance of an Underlying Fund. The Underlying Funds may, subject to
applicable law, purchase investments which are the subject of an 


                                      B-74
<PAGE>
 
underwriting or other distribution by Goldman Sachs or its affiliates and may
also enter transactions with other clients of Goldman Sachs or its affiliates
where such other clients have interests adverse to those of the Underlying
Funds. At times, these activities may cause departments of Goldman Sachs or its
affiliates to give advice to clients that may cause these clients to take
actions adverse to the interests of the Portfolios. To the extent affiliated
transactions are permitted, the Underlying Funds will deal with Goldman Sachs
and its affiliates on an arms-length basis.

      Each Underlying Fund will be required to establish business relationships
with its counterparties based on the Underlying Fund's own credit standing.
Neither Goldman Sachs nor its affiliates will have any obligation to allow their
credit to be used in connection with an Underlying Fund's establishment of its
business relationships, nor is it expected that an Underlying Fund's
counterparties will rely on the credit of Goldman Sachs or any of its affiliates
in evaluating the Underlying Fund's creditworthiness.

      From time to time, Goldman Sachs or any of its affiliates may, but is not
required to, purchase and hold shares of an Underlying Fund in order to increase
the assets of the Underlying Fund. Increasing an Underlying Fund's assets may
enhance investment flexibility and diversification and may contribute to
economies of scale that tend to reduce the Underlying Fund's expense ratio.
Goldman Sachs reserves the right to redeem at any time some or all of the shares
of an Underlying Fund acquired for its own account. A large redemption of shares
of an Underlying Fund by Goldman Sachs could significantly reduce the asset size
of the Underlying Fund, which might have an adverse effect on the Underlying
Fund's investment flexibility, portfolio diversification and expense ratio.
Goldman Sachs will consider the effect of redemptions on an Underlying Fund and
other shareholders in deciding whether to redeem its shares.

      It is possible that an Underlying Fund's holdings will include securities
of entities for which Goldman Sachs performs investment banking services as well
as securities of entities in which Goldman Sachs makes a market. From time to
time, Goldman Sachs' activities may limit the Underlying Funds' flexibility in
purchases and sales of securities. When Goldman Sachs is engaged in an
underwriting or other distribution of securities of an entity, the Underlying
Funds' investment advisers may be prohibited from purchasing or recommending the
purchase of certain securities of that entity for the Underlying Funds.

Distributor and Transfer Agent

      Goldman Sachs serves as the exclusive Distributor of shares of the
Portfolios pursuant to a "best efforts" arrangement as provided by a
distribution agreement with the Trust on behalf of each Portfolio. Shares of the
Portfolios are offered and sold on a continuous basis by Goldman Sachs, acting
as agent. Pursuant to the distribution agreement, after the Portfolios'
Prospectus and periodic reports have been prepared, set in type and mailed to
shareholders, Goldman Sachs will pay for the printing and distribution of copies
thereof used in connection with the offering to prospective investors. Goldman
Sachs will also pay for other supplementary sales literature and advertising
costs. Goldman Sachs has entered into sales agreements with certain investment
dealers and financial service firms (the "Authorized Dealers") to solicit
subscriptions for Class A, Class B and Class C Shares of each of the Portfolios
that offer such classes of shares. Goldman Sachs receives a portion of the sales
load imposed on the sale, in the case of Class A Shares, or redemption in the
case of Class B and Class C Shares, of such Portfolio shares.


                                      B-75

      Goldman Sachs retained approximately the following commissions on sales of
Class A, Class B and Class C Shares during the period ended December 31:

      Goldman Sachs also serves as the Portfolios' transfer and dividend
disbursing agent. Under its transfer agency agreement with the Trust, Goldman
Sachs has undertaken with the Trust with respect to each Portfolio to (i) record
the issuance, transfer and redemption of shares, (ii) provide confirmations of
purchases and redemptions, and quarterly statements, as well as certain other
statements, (iii) provide certain information to the Trust's custodian and the
relevant subcustodian in connection with redemptions, (iv) provide dividend
crediting and certain disbursing agent services, (v) maintain shareholder
accounts, (vi) provide certain state Blue Sky and other information, (vii)
provide shareholders and certain regulatory authorities with tax-related
information, (viii) respond to shareholder inquiries, and (ix) render certain
other miscellaneous services. For its transfer agency services, Goldman Sachs is
entitled to receive a transfer agency fee equal, on an annual basis of 0.04% of
average daily net assets with respect to each Portfolio's Institutional and
Service Shares and 0.19% of average daily net assets with respect to each
Portfolio's Class A, Class B and Class C Shares.

      As compensation for the services rendered to the Portfolios' by Goldman
Sachs as transfer and dividend disbursing agent and the assumption by Goldman
Sachs of the expenses related thereto, Goldman Sachs is entitled to receive fees
from each Portfolio as stated in the Prospectus. For the period ended December
31, 1998 the amounts paid to Goldman Sachs by each Portfolio were as follows
under the fee schedules then in effect:

      The foregoing distribution and transfer agency agreements each provide
that Goldman Sachs may render similar services to others so long as the services
each provides thereunder to the Portfolios are not impaired thereby. Each such
agreement also provides that the Trust will indemnify Goldman Sachs against
certain liabilities.

Expenses

      The Trust, on behalf of each Portfolio, is responsible for the payment of
each Portfolio's respective expenses. The expenses include, without limitation,
the fees payable to the Adviser, service fees paid to Service Organizations, the
fees and expenses payable to the Trust's custodian and subcustodians, transfer
agent fees, brokerage fees and commissions, filing fees for the registration or
qualification of the Trust's shares under federal or state securities laws,
expenses of the organization of the Trust, fees and expenses incurred by the
Trust in connection with membership in investment company organizations, taxes,
interest, costs of liability insurance, fidelity bonds or indemnification, any
costs, expenses or losses arising out of any liability of, or claim for damages
or other relief asserted against, the Trust for violation of any law, legal and
auditing fees and expenses (including the cost of legal and certain accounting
services rendered by employees of GSAM and Goldman Sachs with respect to the
Trust), expenses of preparing and setting in type prospectuses, statements of
additional information, proxy material, reports and notices and the printing and
distributing of the same to the Trust's shareholders and regulatory authorities,
any expenses assumed by a Portfolio pursuant to its distribution and service
plans, compensation and expenses of its "non-interested" Trustees and
extraordinary expenses, if any, incurred by the Trust. Except for fees under any
distribution and service plans applicable to a particular class and transfer
agency fees, all Portfolio expenses are borne on a non-class specific basis.

      The imposition of the Investment Adviser's fee, as well as other operating
expenses, will have the effect of reducing the total return to investors. From
time to time, the Investment Adviser may waive receipt of is fees and/or
voluntarily assume certain expenses of a Fund, which would have the effect of
lowering that Fund's overall expense ratio and increasing total return to
investors at the time such amounts are waived or assumed, as the case may be.

      The Adviser has voluntarily agreed to reduce or limit certain "Other
Expenses" (excluding management, distribution and service fees, taxes, transfer
agency fees, interest, brokerage, litigation, indemnification costs and other
extraordinary expenses) for the Portfolios to the extent such expenses exceed
the percentage of average daily net assets specified in the Portfolios'
Prospectuses. Such reductions or limits, if any, are calculated monthly on a
cumulative basis and may be discontinued or modified by the Adviser in its
discretion at any time.

      The amounts of certain "Other Expenses" of each Portfolio then in
existence that were reduced or otherwise limited were as follows under the
expense limitations that were then in effect for the period ended December 31:

portion of the Adviser's costs of performing certain accounting services not
being provided by a Portfolio's custodian.

Custodian and Sub-Custodians

      State Street, 1776 Heritage Drive, North Quincy, Massachusetts 02171, is
the custodian of the Trust's portfolio securities and cash. State Street also
maintains the Trust's accounting records. State Street may appoint
sub-custodians from time to time to hold certain securities purchased by the
Trust in domestic and foreign and to hold cash for the Trust.

Independent Public Accountants

      Arthur Andersen, LLP, independent public accountants, 225 Franklin Street,
Boston, Massachusetts 02110, have been selected as auditors of the Trust. In
addition to audit services, Arthur Andersen, LLP prepares the Trust's federal
and state tax returns, and provides consultation and assistance on accounting,
internal control and related matters.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

      The Adviser is responsible with respect to the Portfolios (and the
particular investment adviser is responsible with respect to the Underlying
Funds) for decisions to buy and sell securities for the Underlying Fund, the
selection of brokers and dealers to effect the transactions and the negotiation
of brokerage commissions, if any. Purchases and sales of securities on a
securities exchange are effected through brokers who charge a commission for
their services. Orders may be directed to any broker including, to the extent
and in the manner permitted by applicable law, Goldman Sachs.

      In the over-the-counter market, securities are generally traded on a "net"
basis with dealers acting as principal for their own accounts without a stated
commission, although the price of a security usually includes a profit to the
dealer. In underwritten offerings, securities are purchased at a fixed price
which includes an amount of compensation to the underwriter, generally referred
to as the underwriter's concession or discount. On occasion, certain money
market instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid.

      The portfolio transactions for the Underlying Fixed-Income Funds are
generally effected at a net price without a broker's commission (i.e., a dealer
is dealing with an Underlying Fund as principal and receives compensation equal
to the spread between the dealer's cost for a given security and the resale
price of such security). In certain foreign countries, debt securities are
traded on exchanges at fixed commission rates.

      In placing orders for portfolio securities of an Underlying Fund, the
Underlying Funds' investment advisers are generally required to give primary
consideration to obtaining the most favorable execution and net price available.
This means that an investment adviser will seek to execute each transaction at a
price and commission, if any, which provides the most favorable total cost or
proceeds reasonably attainable in the circumstances. As permitted by Section
28(e) of the Securities Exchange Act of 1934, the Underlying Fund may pay a
broker which provides brokerage and research services an amount of disclosed
commission in excess of the commission which another broker would have charged
for effecting that transaction. Such practice is subject to a good faith
determination by the Trustees that such commission is reasonable in light of the
services provided and to such policies as the Trustees may adopt from time to


                                      B-78
<PAGE>
 
time. While the Underlying Funds' investment advisers generally seek reasonably
competitive spreads or commissions, an Underlying Fund will not necessarily be
paying the lowest spread or commission available. Within the framework of this
policy, the investment advisers will consider research and investment services
provided by brokers or dealers who effect or are parties to portfolio
transactions of an Underlying Fund, the investment advisers and their
affiliates, or their other clients. Such research and investment services are
those which brokerage houses customarily provide to institutional investors and
include research reports on particular industries and companies, economic
surveys and analyses, recommendations as to specific securities and other
products or services (e.g., quotation equipment and computer related costs and
expenses), advice concerning the value of securities, the advisability of
investing in, purchasing or selling securities, the availability of securities
or the purchasers or sellers of securities, furnishing analyses and reports
concerning issuers, industries, securities, economic factors and trends,
portfolio strategy and performance of accounts, effecting securities
transactions and performing functions incidental thereto (such as clearance and
settlement) and providing lawful and appropriate assistance to the investment
advisers in the performance of their decision-making responsibilities. Such
services are used by the investment advisers in connection with all of their
investment activities, and some of such services obtained in connection with the
execution of transactions for an Underlying Fund may be used in managing other
investment accounts. Conversely, brokers furnishing such services may be
selected for the execution of transactions of such other accounts, whose
aggregate assets are far larger than those of an Underlying Fund, and the
services furnished by such brokers may be used by the investment advisers in
providing management services for the Trust.

      In circumstances where two or more broker-dealers offer comparable prices
and execution capability, preference may be given to a broker-dealer which has
sold shares of an Underlying Fund as well as shares of other investment
companies or accounts managed by the Underlying Funds' investment advisers. This
policy does not imply a commitment to execute all portfolio transactions through
all broker-dealers that sell shares of the Underlying Fund.

      On occasions when an Underlying Fund's investment adviser deems the
purchase or sale of a security to be in the best interest of an Underlying Fund
as well as its other customers (including any other fund or other investment
company or advisory account for which such investment adviser acts as investment
adviser of sub-investment adviser), the investment adviser, to the extent
permitted by applicable laws and regulations, may aggregate the securities to be
sold or purchased for the Underlying Fund with those to be sold or purchased for
such other customers in order to obtain the best net price and most favorable
execution under the circumstances. In such event, allocation of the securities
so purchased or sold, as well as the expenses incurred in the transaction, will
be made by the applicable investment adviser in the manner it considers to be
equitable and consistent with its fiduciary obligations to such Underlying Fund
and such other customers. In some instances, this procedure may adversely affect
the price and size of the position obtainable for an Underlying Fund.

      Commission rates in the U.S. are established pursuant to negotiations with
the broker based on the quality and quantity of execution services provided by
the broker in the light of generally prevailing rates. The allocation of orders
among brokers and the commission rates paid are reviewed periodically by the
Trustees.

      Subject to the above considerations, the Underlying Funds' investment
advisers may use Goldman Sachs as a broker for an Underlying Fund. In order for
Goldman Sachs to effect any portfolio transactions for an Underlying Fund, the
commissions, fees or other remuneration received by Goldman Sachs must be
reasonable and fair compared to the commissions, fees or other remuneration paid
to other brokers in connection with comparable transactions involving similar
instruments being purchased or sold on an 


                                      B-79
<PAGE>
 
exchange during a comparable period of time. This standard would allow Goldman
Sachs to receive no more than the remuneration which would be expected to be
received by an unaffiliated broker in a commensurate arm's-length transaction.
Furthermore, the Trustees, including a majority of the Trustees who are not
"interested" Trustees, have adopted procedures which are reasonably designed to
provide that any commissions, fees or other remuneration paid to Goldman Sachs
are consistent with the foregoing standard. Brokerage transactions with Goldman
Sachs are also subject to such fiduciary standards as may be imposed upon
Goldman Sachs by applicable law.

      During the fiscal year ended December 31, 1998, the Portfolios acquired
and sold securities of their regular broker-dealers: Nationsbanc Montgomery
Securities, Donaldson, Lufkin & Jenrette, Salomon Smith Barney, Bear Stearns,
Lehman Brothers, Nomura Securities, J.P. Morgan, ABN/AMRO Securities, Chase
Manhattan Securities and C.S. First Boston Corp. At December 31, 1998, the
Balanced Strategy Portfolio held the following amounts of securities of its
regular broker/dealers as defined in Rule 10b-1 under the Act or their parents
($ in thousands): Nationsbanc Montgomery Securities ($18), Donaldson, Lufkin &
Jenrette ($11), J.P. Morgan ($102) and ABN/AMRO Securities ($18).

                                 NET ASSET VALUE

      Under the Act, the Trustees are responsible for determining in good faith
the fair value of securities of each Portfolio. In accordance with procedures
adopted by the Trustees, the net asset value per share of each class of each
Portfolio is calculated by determining the value of the net assets attributed to
each class of that Portfolio and dividing by the number of outstanding shares of
that class. All securities are valued as of the close of regular trading on the
New York Stock Exchange (normally, but not always, 4:00 p.m. New York time) on
each Business Day. The term "Business Day" means any day the New York Stock
Exchange is open for trading which is Monday through Friday except for holidays.
The New York Stock Exchange is closed on the following holidays: New Year's Day,
Martin Luther King, Jr. Day, Presidents' Day (observed), Good Friday, Memorial
Day (observed), Independence Day (observed), Labor Day, Thanksgiving Day and
Christmas Day (observed).

      In the event that the New York Stock Exchange or the national securities
exchange on which stock options are traded adopt different trading hours on
either a permanent or temporary basis, the Trustees will reconsider the time at
which net asset value is computed. In addition, each Portfolio may compute its
net asset value as of any time permitted pursuant to any exemption, order or
statement of the SEC or its staff.

      In determining the net asset value of a Portfolio, the net asset value of
the Underlying Funds' shares held by the Portfolio will be their net asset value
at the time of computation. Financial Square Prime Obligations Fund values all
of its portfolio securities using the amortized cost valuation method pursuant
to Rule 2a-7 under the Act. Other portfolio securities for which accurate market
quotations are available are valued by a Portfolio or Underlying Fund as
follows: (a) securities listed on any U.S. or foreign stock exchange or on the
National Association of Securities Dealers Automated Quotations System
("NASDAQ") will be valued at the last sale price on the exchange or system in
which they are principally traded on the valuation date. If there is no sale on
the valuation day, securities traded will be valued at the closing bid price, or
if closing a bid price is not available, at either the exchange or
system-defined close price on the exchange or system in which such securities
are principally traded. If the relevant exchange or system has not closed by the
above-mentioned time for determining the Underlying Fund's net asset value, the
securities will be valued at the last sale price or, if not available, at the
bid price at the time the net asset value is determined; (b) over-the-counter
securities not quoted on NASDAQ will be valued at the last sale price on the
valuation day or, if no sale occurs, at the last bid price at the time net asset
value is determined; (c) equity securities for which no prices are obtained
under sections (a) or (b) hereof, including those for 


                                      B-80
<PAGE>
 
which a pricing service supplies no exchange quotation or a quotation that is
believed by the portfolio manager/trader to be inaccurate, will be valued at
their fair value in accordance with procedures approved by the Board of
Trustees; (d) fixed-income securities with a remaining maturity of 60 days or
more for which accurate market quotations are readily available will normally be
valued according to dealer-supplied bid quotations or bid quotations from a
recognized pricing service (e.g., Merrill Lynch, J.J. Kenny, Muller Data Corp.,
Bloonberg, EJV, Reuters or Standard & Poor's); (e) fixed-income securities for
which quotations are not readily available are valued by the investment adviser
based on valuation models that take into account spread and daily yield changes
on government securities in the appropriate market (i.e. matrix pricing); (f)
debt securities with a remaining maturity of 60 days or less are valued by the
particular investment adviser at amortized cost, which the Trustees have
determined to approximate fair value; and (g) all other instruments, including
those for which a pricing service supplies no exchange quotation or a quotation
that is believed by the portfolio manager/trader to be inaccurate, will be
valued at fair value in accordance with the valuation procedures approved by the
Board of Trustees.

      The value of all assets and liabilities expressed in foreign currencies
will be converted into U.S. dollar values at current exchange rates of such
currencies against U.S. dollars last quoted by any major bank. If such
quotations are not available, the rate of exchange will be determined in good
faith by or under procedures established by the Board of Trustees.

      Generally, trading in securities on European and Far Eastern securities
exchanges and on over-the-counter markets is substantially completed at various
times prior to the close of business on each Business Day in New York (i.e., a
day on which the New York Stock Exchange is open for trading). In addition,
European or Far Eastern securities trading generally or in a particular country
or countries may not take place on all Business Days in New York. Furthermore,
trading takes place in various foreign markets on days which are not Business
Days in New York and days on which the Underlying Funds' net asset values are
not calculated. Such calculation does not take place contemporaneously with the
determination of the prices of the majority of the portfolio securities used in
such calculation. The impact of events that occur after the publication of
market quotations used by a Fund to price its securities but before the close of
regular trading on the New York Stock Exchange will normally not be reflected in
an Underlying Fund's next determined net asset value unless the Trust, in its
discretion, makes an adjustment in light of the nature and materiality of the
event, its effect on Fund operations and other relevant factors.

      The proceeds received by each Portfolio and each other series of the Trust
from the issue or sale of its shares, and all net investment income, realized
and unrealized gain and proceeds thereof, subject only to the rights of
creditors, will be specifically allocated to such Portfolio and constitute the
underlying assets of that Portfolio or series. The underlying assets of each
Portfolio will be segregated on the books of account, and will be charged with
the liabilities in respect of such Portfolio and with a share of the general
liabilities of the Trust. Expenses of the Trust with respect to the Portfolios
and the other series of the Trust are generally allocated in proportion to the
net asset values of the respective Portfolios or series except where allocations
of direct expenses can otherwise be fairly made.

                             PERFORMANCE INFORMATION

      A Portfolio may from time to time quote or otherwise use total return,
yield and/or distribution rate information in advertisements, shareholder
reports or sales literature. Average annual total return and yield are computed
pursuant to formulas specified by the SEC.


                                      B-81
<PAGE>
 
      Yield is computed by dividing net investment income earned during a recent
thirty-day period by the product of the average daily number of shares
outstanding and entitled to receive dividends during the period and the maximum
public offering price per share on the last day of the relevant period. The
results are compounded on a bond equivalent (semi-annual) basis and then
annualized. Net investment income per share is equal to the dividends and
interest earned during the period, reduced by accrued expenses for the period.
The calculation of net investment income for these purposes may differ from the
net investment income determined for accounting purposes.

      The distribution rate for a specified period is calculated by annualizing
distributions of net investment income for such period and dividing this amount
by the net asset value per share or maximum public offering price on the last
day of the period.

      Average annual total return for a specified period is derived by
calculating the actual dollar amount of the investment return on a $1,000
investment made at the maximum public offering price applicable to the relevant
class (i.e., net asset value in the case of each class other than Class A) at
the beginning of the period, and then calculating the annual compounded rate of
return which would produce that amount, assuming a redemption (and payment of
any contingent deferred sales charge) at the end of the period. This calculation
assumes a complete redemption of the investment. It also assumes that all
dividends and distributions are reinvested at net asset value on the
reinvestment dates during the period.

      Year-by-year total return and cumulative total return for a specified
period are each derived by calculating the percentage rate required to make a
$1,000 investment (made at the maximum public offering price with all
distributions reinvested) at the beginning of such period equal to the actual
total value of such investment at the end of such period.

      Total return calculations for Class A Shares reflect the effect of paying
the maximum initial sales charge. Investment at a lower sales charge would
result in higher performance figures. Total return calculations for Class B and
Class C Shares reflect deduction of the applicable CDSC imposed upon redemption
of Class B and Class C Shares held for the applicable period. Each Portfolio may
also from time to time advertise total return on a cumulative, average,
year-by-year or other basis for various specified periods by means of
quotations, charts, graphs or schedules. In addition, each Portfolio may furnish
total return calculations based on investments at various sales charge levels or
at NAV. Any performance information which is based on a Portfolio's net asset
value per share would be reduced if any applicable sales charge were taken into
account. In addition to the above, each Portfolio may from time to time
advertise its performance relative to certain averages, performance rankings,
indices, other information prepared by recognized mutual fund statistical
services and investments for which reliable performance information is
available. The Portfolios' performance quotations do not reflect any fees
charged by an Authorized Dealer, Service Organization or other financial
intermediary to its customer accounts in connection with investments in the
Portfolios.

      Thirty-day yield, distribution rate and average annual total return are
calculated separately for each class of shares of each Portfolio. Each class of
shares of each Portfolio is subject to different fees and expenses and may have
different returns for the same period.

      Occasionally, statistics may be used to specify Portfolio volatility or
risk. Measures of volatility or risk are generally used to compare a Portfolio's
net asset value or performance relative to a market index. One measure of
volatility is beta. Beta is the volatility of a Portfolio relative to the total
market. A beta of more than 1.00 indicates volatility greater than the market,
and a beta of less than 1.00 indicates volatility less than the market. Another
measure of volatility or risk is standard deviation. Standard deviation is used


                                      B-82
<PAGE>
 
to measure variability of net asset value or total return around an average,
over a specified period of time. The premise is that greater volatility connotes
greater risk undertaken in achieving performance.

      From time to time the Trust may publish an indication of a Portfolio's
past performance as measured by independent sources such as (but not limited to)
Lipper Analytical Services, Inc., Morningstar Mutual Funds, Weisenberger

generally unmanaged and the items included in the calculations of such indices
and averages may not be identical to the formulas used by a Portfolio to
calculate its performance figures.

      A Portfolio's performance data will be based on historical results and
will not be intended to indicate future performance. A Portfolio's total return,
yield and distribution rate will vary based on market conditions, portfolio
expenses, portfolio investments and other factors. The value of a Portfolio's
shares will fluctuate and an investor's shares may be worth more or less than
their original cost upon redemption.

      The Trust may, at its discretion, from time to time make a list of a
Portfolio's holdings available to investors upon request.

                               SHARES OF THE TRUST

      Each Portfolio is a series of Goldman Sachs Trust, which was formed under
the laws of the state of Delaware on January 28, 1997. The Trustees have
authority under the Trust's Declaration of Trust to create and classify shares
of beneficial interest in separate series, without further action by
shareholders. The Trustees also have authority to classify and reclassify the
shares of the Portfolios into one or more classes of shares. As of the date of
this Additional Statement, the Trustees have authorized the issuance of five
classes of shares in each Portfolio: Institutional Shares, Service Shares, Class
A Shares, Class B Shares and Class C Shares.

      Each Institutional Share, Service Share, Class A Share, Class B Share and
Class C Share of a Portfolio represents a proportionate interest in the assets
belonging to the applicable class of the Portfolio. All expenses of a Portfolio
are borne at the same rate by each class of shares, except that fees under
Service Plan are borne exclusively by Service Shares, fees under the
Distribution and Service Plan are borne exclusively by Class A Shares, Class B
Shares or Class C Shares, and transfer agency fees may be borne at different
rates by different share classes. The Trustees may determine in the future that
it is appropriate to

allocate other expenses differently between classes of shares and may do so to
the extent consistent with the rules of the SEC and positions of the Internal
Revenue Service. Each class of shares may have different minimum investment
requirements and be entitled to different shareholder services. With limited
exceptions, shares of a class may only be exchanged for shares of the same or an
equivalent class of another series. See "Shareholder Guide" in the Prospectus.

      Institutional Shares may be purchased at net asset value without a sales
charge for accounts in the name of an investor or institution that is not
compensated by a Portfolio under a Plan for services provided to the
institution's customers.

      Service Shares may be purchased at net asset value without a sales charge
for accounts held in the name of an institution that, directly or indirectly,
provides certain account administration and shareholder liaison services to its
customers, including maintenance of account records and processing orders to
purchase, redeem and exchange Service Shares. Service Shares bear the cost of
account administration fees at the annual rate of up to 0.50% of the average
daily net assets of the Portfolio attributable to Service Shares.

      Class A Shares are sold, with an initial sales charge, through brokers and
dealers who are members of the National Association of Securities Dealers, Inc.
and certain other financial service firms that have sales agreements with
Goldman Sachs. Class A Shares of the Portfolios bear the cost of distribution
(Rule 12b-1) fees at the aggregate rate of up to 0.25% of the average daily net
assets of such Class A Shares. With respect to Class A Shares, the Distributor
at its discretion may use compensation for distribution services paid under the
Distribution and Services Plan for personal and account maintenance services and
expenses so long as such total compensation under the Plan does not exceed the
maximum cap on "service fees" imposed by the NASD.

      Class B Shares and Class C Shares of the Portfolios are sold subject to a
contingent deferred sales charge through brokers and dealers who are members of
the National Association of Securities Dealers, Inc. and certain other financial
services firms that have sales arrangements with Goldman Sachs. Class B Shares
and Class C Shares bear the cost of distribution (Rule 12b-1) fees at the
aggregate rate of up to 0.75% of the average daily net assets attributed to
Class B Shares and Class C Shares. Class B Shares and Class C Shares also bear
the cost of a service fee at an annual rate of up to 0.25% of the average daily
net assets attributed to Class B Shares and Class C Shares.

      It is possible that an institution or its affiliate may offer different
classes of shares (i.e., Institutional, Service, Class A, Class B and Class C
Shares) to its customers and thus receive different compensation with respect to
different classes of shares of each Portfolio. Dividends paid by each Portfolio,
if any, with respect to each class of shares will be calculated in the same
manner, at the same time on the same day and will be in the same amount, except
for differences caused by the differences in expenses discussed above.
Similarly, the net asset value per share may differ depending upon the class of
shares purchased.

      Certain aspects of the shares may be altered after advance notice to
shareholders if it is deemed necessary in order to satisfy certain tax
regulatory requirements.

      When issued, shares are fully paid and non-assessable. In the event of
liquidation, shareholders are entitled to share pro rata in the net assets of
the applicable class of the relevant Portfolio available for distribution to
such shareholders. All shares are freely transferable and have no preemptive,
subscription or conversion rights.

      In the interest of economy and convenience, the Trust does not issue
certificates representing the Portfolios' shares. Instead, the Transfer Agent
maintains a record of each shareholder's ownership. Each shareholder receives
confirmation of purchase and redemption orders from the Transfer Agent.
Portfolio shares and any dividends and distributions paid by the Portfolios are
reflected in account statements from the Transfer Agent.

      The Act requires that where more than one class or series of shares
exists, each class or series must be preferred over all other classes or series
in respect to assets specifically allocated to such class or series. In
addition, Rule 18f-2 under the Act provides that any 


                                      B-92
<PAGE>
 
matter required to be submitted by the provisions of the Act or applicable state
law, or otherwise, to the holders of the outstanding voting securities of an
investment company such as the Trust shall not be deemed to have been
effectively acted upon unless approved by the holders of a majority of the
outstanding shares of each class or series affected by such matter. Rule 18f-2
further provides that a class or series shall be deemed to be affected by a
matter unless the interests of each class or series in the matter are
substantially identical or the matter does not affect any interest of such class
or series. However, Rule 18f-2 exempts the selection of independent public
accountants, the approval of principal distribution contracts and the election
of trustees from the separate voting requirements of Rule 18f-2.

      The Trust is not required to hold annual meetings of shareholders and does
not intend to hold such meetings. In the event that a meeting of shareholders is
held, each share of the Trust will be entitled, as determined by the Trustees,
either to one vote for each share or to one vote for each dollar of net asset
value represented by such shares on all matters presented to shareholders
including the elections of Trustees (this method of voting being referred to as
"dollar based voting"). However, to the extent required by the Act or otherwise
determined by the Trustees, series and classes of the Trust will vote separately
from each other. Shareholders of the Trust do not have cumulative voting rights
in the election of Trustees. Meetings of shareholders of the Trust, or any
series or class thereof, may be called by the Trustees, certain officers or upon
the written request of holders of 10% or more of the shares entitled to vote at
such meetings. The Trustees will call a special meeting of shareholders for the
purpose of electing Trustees if, at any time, less than a majority of Trustees
holding office at the time were elected by shareholders. The shareholders of the
Trust will have voting rights only with respect to the limited number of matters
specified in the Declaration of Trust and such other matters as the Trustees may
determine or may be required by law.

      The Declaration of Trust provides for indemnification of Trustees,
officers, employees and agents of the Trust unless the recipient is adjudicated
(i) to be liable by reason of willful misfeasance, bad faith, gross negligence
or reckless disregard of the duties involved in the conduct of such person's
office or (ii) not to have acted in good faith in the reasonable belief that
such person's actions were in the best interest of the Trust. The Declaration of
Trust provides that, if any shareholder or former shareholder of any series is
held personally liable solely by reason of being or having been a shareholder
and not because of the shareholder's acts or omissions or for some other reason,
the shareholder or former shareholder (or heirs, executors, administrators,
legal representatives or general successors) shall be held harmless from and
indemnified against all loss and expense arising from such liability. The Trust,
acting on behalf of any affected series, must, upon request by such shareholder,
assume the defense of any claim made against such shareholder for any act or
obligation of the series and satisfy any judgment thereon from the assets of the
series.

      The Declaration of Trust permits the termination of the Trust or of any
series or class of the Trust (i) by a majority of the affected shareholders at a
meeting of shareholders of the Trust, series or class; or (ii) by a majority of
the Trustees without shareholder approval if the Trustees determine that such
action is in the best interest of the Trust, series or its respective
shareholders. The factors and events that the Trustees may take into account in
making such determination include (i) the inability of the Trust or any
successor series or class to maintain its assets at an appropriate size; (ii)
changes in laws or regulations governing the Trust, series or class or affecting
assets of the type in which it invests; or (iii) economic developments or trends
having a significant adverse impact on their business or operations.


                                      B-93
<PAGE>
 
      The Declaration of Trust authorizes the Trustees without shareholder
approval to cause the Trust, or any series thereof, to merge or consolidate with
any corporation, association, trust or other organization or sell or exchange
all or substantially all of the property belonging to the Trust or any series
thereof. In addition, the Trustees, without shareholder approval, may adopt a
master-feeder structure by investing all or a portion of the assets of a series
of the Trust in the securities of another open-end investment company with
substantially the same investment objective, restrictions and policies.

      The Declaration of Trust permits the Trustees to amend the Declaration of
Trust without a shareholder vote. However, shareholders of the Trust have the
right to vote on any amendment (i) that would adversely affect the voting rights
of shareholders; (ii) that is required by law to be approved by shareholders;
(iii) that would amend the provisions of the Declaration of Trust regarding
amendments and supplements thereto; or (iv) that the Trustees determine to
submit to shareholders.

      The Trustees may appoint separate Trustees with respect to one or more
series or classes of the Trust's shares (the "Series Trustees"). Series Trustees
may, but are not required to, serve as Trustees of the Trust or any other series
or class of the Trust. The Series Trustees have, to the exclusion of any other
Trustees of the Delaware Trust, all the powers and authorities of Trustees under
the Trust Instrument with respect to any other series or class.

Shareholder and Trustee Liability

      Under Delaware law, the shareholders of the Portfolios are not generally
subject to liability for the debts or obligations of the Trust. Similarly,
Delaware law provides that a series of the Trust will not be liable for the
debts or obligations of any other series of the Trust. However, no similar
statutory or other authority limiting business trust shareholder liability
exists in other states. As a result, to the extent that a Delaware business
trust or a shareholder is subject to the jurisdiction of courts of such other
states, the courts may not apply Delaware law and may thereby subject the
Delaware business trust shareholders to liability. To guard this risk, the
Declaration of Trust contains an express disclaimer of shareholder liability for
acts or obligations of a Portfolio. Notice of such disclaimer will normally be
given in each agreement, obligation or instrument entered into or executed by a
series or the Trustees. The Declaration of Trust provides for indemnification by
the relevant Portfolio for all loss suffered by a shareholder as a result of an
obligation of the series. The Declaration of Trust also provides that a series
shall, upon request, assume the defense of any claim made against any
shareholder for any act or obligation of the series and satisfy any judgment
thereon. In view of the above, the risk of personal liability of shareholders of
a Delaware business trust is remote.

      In addition to the requirements under Delaware law, the Declaration of
Trust provides that shareholders of a series may bring a derivative action on
behalf of the series only if the following conditions are met: (a) shareholders
eligible to bring such derivative action under Delaware law who hold at least
10% of the outstanding shares of the series, or 10% of the outstanding shares of
the class to which such action relates, shall join in the request for the
Trustees to commence such action; and (b) the Trustees must be afforded a
reasonable amount of time to consider such shareholder request and to
investigate the basis and to employ other advisers in considering the merits of
the request and shall require an 


                                      B-94
<PAGE>
 
undertaking by the shareholders making such request to reimburse the Portfolio
for the expense of any such advisers in the event that the Trustees determine
not to bring such action.

      The Declaration of Trust further provides that the Trustees will not be
liable for errors of judgment or mistakes of fact or law, but nothing in the
Declaration of Trust protects a Trustee against liability to which he or she
would otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties involved in the conduct of his
or her office.

                                    TAXATION

      The following is a summary of the principal U.S. federal income, and
certain state and local, tax considerations regarding the purchase, ownership
and disposition of shares in each Portfolio. This summary does not address
special tax rules applicable to certain classes of investors, such as tax-exempt
entities, insurance companies and financial institutions. Each prospective
shareholder is urged to consult his or her own tax adviser with respect to the
specific federal, state, local and foreign tax consequences of investing in each
Portfolio. The summary is based on the laws in effect on the date of this
Additional Statement, which are subject to change.

General

      Each Portfolio is a separate taxable entity. Each of the Portfolios
intends to qualify for each taxable year as a regulated investment company under
Subchapter M of the Internal Revenue Code, as amended (the "Code").

      Qualification as a regulated investment company under the Code requires,
among other things, that (a) a Portfolio derive at least 90% of its gross income
for its taxable year from dividends, interest, payments with respect to
securities loans and gains from the sale or other disposition of stocks or
securities or foreign currencies, or other income (including but not limited to
gains from options, futures, and forward contracts) derived with respect to its
business of investing in such stock, securities or currencies (the "90% gross
income test"); and (b) such Portfolio diversify its holdings so that, at the
close of each quarter of its taxable year, (i) at least 50% of the market value
of such Portfolio's total (gross) assets is comprised of cash, cash items, U.S.
Government securities, securities of other regulated investment companies and
other securities limited in respect of any one issuer to an amount not greater
in value than 5% of the value of such Portfolio's total assets and to not more
than 10% of the outstanding voting securities of such issuer, and (ii) not more
than 25% of the value of its total (gross) assets is invested in the securities
of any one issuer (other than U.S. Government securities and securities of other
regulated investment companies) or two or more issuers controlled by the
Portfolio and engaged in the same, similar or related trades or businesses.

      If a Portfolio complies with such provisions, then in any taxable year in
which such Portfolio distributes, in compliance with the Code's timing and other
requirements, at least 90% of its "investment company taxable income" (which
includes dividends, taxable interest, 


                                      B-95
<PAGE>
 
taxable accrued original issue discount and market discount income, income from
securities lending, any net short-term capital gain in excess of net long-term
capital loss, certain net realized foreign exchange gains and any other taxable
income other than "net capital gain," as defined below, and is reduced by
deductible expenses), and at least 90% of the excess of its gross tax-exempt
interest income (if any) over certain disallowed deductions, such Portfolio (but
not its shareholders) will be relieved of federal income tax on any income of
the Portfolio, including long-term capital gains, distributed to shareholders.
In this connection, dividends received by a Portfolio from an Underlying Fund,
other than capital gain distributions, are treated as ordinary income to the
Portfolio. Distributions from an Underlying Fund designated as capital gain
distributions are treated as long-term capital gains. Such long-term capital
gain will generally be taxed at a maximum rate of 20%. In addition, upon the
sale or other disposition by a Portfolio of shares of an Underlying Fund or
other investment, the Portfolio will generally realize a capital gain or loss
which will be long-term or short-term, generally depending upon the Portfolio's
holding period.

      If a Portfolio retains any investment company taxable income or "net
capital gain" (the excess of net long-term capital gain over net short-term
capital loss), it will be subject to a tax at regular corporate rates on the
amount retained. If a Portfolio retains any net capital gain, the Portfolio may
designate the retained amount as undistributed capital gains in a notice to its
shareholders who, if subject to U.S. federal income tax on long-term capital
gains, (i) will be required to include in income for federal income tax
purposes, as long-term rate capital gain, as the case may be, their shares of
such undistributed amount, and (ii) will be entitled to credit their
proportionate shares of the tax paid by the Portfolio against their U.S. federal
income tax liabilities, if any, and to claim refunds to the extent the credit
exceeds such liabilities. For U.S. federal income tax purposes, the tax basis of
shares owned by a shareholder of the Portfolio will be increased by an amount
equal to a percentage of the amount of undistributed net capital gain included
in the shareholder's gross income. Each Portfolio intends to distribute for each
taxable year to its shareholders all or substantially all of its investment
company taxable income, net capital gain and any net tax-exempt interest.
Exchange control or other foreign laws, regulations or practices may restrict
repatriation of investment income, capital or the proceeds of securities sales
by foreign investors such as the CORE International Equity, International
Equity, European Equity, Japanese Equity, International Small Cap, Emerging
Markets Equity, Asia Growth or Global Income Funds and may therefore make it
more difficult for such a Fund to satisfy the distribution requirements
described above, as well as the excise tax distribution requirements described
below. However, each Fund generally expects to be able to obtain sufficient cash
to satisfy such requirements from new investors, the sale of securities or other
sources. If for any taxable year a Portfolio does not qualify as a regulated
investment company, it will be taxed on all of its investment company taxable
income and net capital gain at corporate rates, and its distributions to
shareholders will be taxable as ordinary dividends to the extent of its current
and accumulated earnings and profits.

      In order to avoid a 4% federal excise tax, each Portfolio must distribute
(or be deemed to have distributed) by December 31 of each calendar year at least
98% of its taxable ordinary income for such year, at least 98% of the excess of
its capital gains over its capital losses (generally computed on the basis of
the one-year period ending on October 31 of such year), and all taxable ordinary
income and the excess of capital gains over capital losses for the previous year
that were not distributed for such year and on which the Portfolio paid no
federal income tax. For federal income tax purposes, dividends declared by a
Portfolio in 


                                      B-96
<PAGE>
 
October, November or December to shareholders of record on a specified date in
such a month and paid during January of the following year are taxable to such
shareholders as if received on December 31 of the year declared. The Portfolios
anticipate that they will generally make timely distributions of income and
capital gains in compliance with these requirements so that they will generally
not be required to pay the excise tax. For federal income tax purposes, each
Portfolio is permitted to carry forward a net capital loss in any year to offset
its own capital gains, if any, during the eight years following the year of the
loss.

      Gains and losses on the sale, lapse, or other termination of options and
futures contracts, options thereon and certain forward contracts (except certain
foreign currency options, forward contracts and futures contracts) will
generally be treated as capital gains and losses. Certain of the futures
contracts, forward contracts and options held by an Underlying Fund will be
required to be "marked-to-market" for federal income tax purposes, that is,
treated as having been sold at their fair market value on the last day of the
Fund's taxable year. These provisions may require an Underlying Fund to
recognize income or gains without a concurrent receipt of cash. Any gain or loss
recognized on actual or deemed sales of these futures contracts, forward
contracts, or options will (except for certain foreign currency options, forward
contracts, and futures contracts) be treated as 60% long-term capital gain or
loss and 40% short-term capital gain or loss. As a result of certain hedging
transactions entered into by an Underlying Fund, the Fund may be required to
defer the recognition of losses on futures contracts, forward contracts, and
options or underlying securities or foreign currencies to the extent of any
unrecognized gains on related positions held by such Underlying Fund and the
characterization of gains or losses as long-term or short-term may be changed.
The tax provisions described above applicable to options, futures and forward
contracts may affect the amount, timing and character of an Underlying Fund's
distributions to shareholders. Application of certain requirements for
qualification as a regulated investment company and/or these tax rules to
certain investment practices, such as dollar rolls, or certain derivatives such
as interest rate swaps, floors, caps and collars and currency, mortgage or index
swaps may be unclear in some respects, and an Underlying Fund may therefore be
required to limit its participation in such transactions. Certain tax elections
may be available to an Underlying Fund to mitigate some of the unfavorable
consequences described in this paragraph.

      Section 988 of the Code contains special tax rules applicable to certain
foreign currency transactions and instruments that may affect the amount, timing
and character of income, gain or loss recognized by an Underlying Fund. Under
these rules, foreign exchange gain or loss realized with respect to foreign
currencies and certain futures and options thereon, foreign currency-denominated
debt instruments, foreign currency forward contracts, and foreign
currency-denominated payables and receivables will generally be treated as
ordinary income or loss, although in some cases elections may be available that
would alter this treatment. If a net foreign exchange loss treated as ordinary
loss under Section 988 of the Code were to exceed an Underlying Fund's
investment company taxable income (computed without regard to such loss) for a
taxable year, the resulting loss would not be deductible by the Fund or its
shareholders in future years. Net loss, if any, from certain of the foregoing
currency transactions or instruments could exceed net investment income
otherwise calculated for accounting purposes with the result being either no
dividends being paid or a portion of an Underlying Fund's dividends being
treated as a return of capital for tax purposes, nontaxable to the extent of a
shareholder's tax basis in his shares and, once such basis is exhausted,
generally giving rise to capital gains.

      An Underlying Fund's investment in zero coupon securities, deferred
interest securities, certain structured securities or other securities bearing
original issue discount or, if an Underlying Fund elects to include market
discount in income currently, market discount, as well as any "mark to market"
gain from certain options, futures or forward contracts, as described above,
will generally cause it to realize income or gain prior to the receipt of cash
payments with respect to these securities or contracts. In order to obtain cash
to enable it to distribute this income or gain, maintain its qualification as a
regulated investment company and avoid federal income or excise taxes, the
Underlying Fund may be required to liquidate portfolio securities that it might
otherwise have continued to hold.

      Each Underlying Fund also intends to qualify annually and elect to be
treated as a regulated investment company under Subchapter M of the Code. In any
year in which an Underlying Fund so qualifies and timely distributes all of its
taxable income, the Underlying Fund generally will not pay any federal income or
excise tax. If, as may occur for certain of the Underlying Funds, more than 50%
of an Underlying Fund's total assets at the close of any taxable year consists
of stock or securities of foreign corporations, the Underlying Fund may file an
election with the Internal Revenue Service pursuant to which shareholders of the
Underlying Fund would be required to (i) include in ordinary gross income (in
addition to taxable dividends actually received) their pro rata shares of
foreign income taxes paid by the Underlying Fund that are treated as income
taxes under U.S. tax regulations (which excludes, for example, stamp taxes,
securities transaction taxes, and similar taxes) even though not actually
received by such shareholders, and (ii) treat such respective pro rata portions
as foreign income taxes paid by them.

      If an Underlying Fund makes this election, its shareholders may then
deduct such pro rata portions of qualified foreign taxes in computing their
taxable incomes, or, alternatively, use them as foreign tax credits, subject to
applicable limitations, against their U.S. federal income taxes. Shareholders
who do not itemize deductions for federal income tax purposes will not, however,
be able to deduct their pro rata portion of foreign taxes paid by an Underlying
Fund, although such shareholders will be required to include their shares of
such taxes in gross income if the election is made.

      While a Portfolio will be able to deduct the foreign taxes that it will be
treated as receiving from an Underlying Fund if the election is made, the
Portfolio will not itself be able to elect to treat its foreign taxes as paid by
its shareholders. Accordingly, the shareholders of the Portfolio will not have
an option of claiming a foreign tax credit for foreign taxes paid by the
Underlying Funds, while persons who invest directly in such Underlying Funds may
have that option.

      If an Underlying Fund acquires stock (including, under proposed
regulations, an option to acquire stock such as is inherent in a convertible
bond) in certain foreign corporations that receive at least 75% of their annual
gross income from passive sources (such as interest, dividends, rents, royalties
or capital gain) or hold at least 50% of their assets in investments producing
such passive income ("passive foreign investment companies"), the Underlying
Fund could be subject to federal income tax and additional interest charges on
"excess distributions" received from such companies or gain from the sale of
stock in such companies, even if all income or gain actually received by the
Underlying Fund is timely distributed to its shareholders. The Underlying Fund
would not be able to pass through to its shareholders any credit or deduction
for such a tax. In some cases, elections may be


                                      B-98
<PAGE>
 
available that would ameliorate these adverse tax consequences, but such
elections would require the Underlying Fund to include certain amounts as income
or gain (subject to the distribution requirements described above) without a
concurrent receipt of cash. Each Fund may limit and/or manage its holdings in
passive foreign investment companies to minimize its tax liability or maximize
its return from these investments.

      Investments in lower-rated securities may present special tax issues for
an Underlying Fund to the extent actual or anticipated defaults may be more
likely with respect to such securities. Tax rules are not entirely clear about
issues such as when an Underlying Fund may cease to accrue interest, original
issue discount, or market discount; when and to what extent deductions may be
taken for bad debts or worthless securities; how payments received on
obligations in default should be allocated between principal and income; and
whether exchanges of debt obligations in a workout context are taxable. These
and other issues will be addressed by an Underlying Fund, in the event it
invests in such securities, in order to seek to eliminate or minimize any
adverse tax consequences.

Taxable U.S. Shareholders - Distributions

      For U.S. federal income tax purposes, distributions by a Portfolio
generally will be taxable to shareholders who are subject to tax. Shareholders
receiving a distribution in the form of newly issued shares will be treated for
U.S. federal income tax purposes as receiving a distribution in an amount equal
to the amount of cash they would have received had they elected to receive cash
and will have a cost basis in each share received equal to such amount divided
by the number of shares received.

      Distributions from investment company taxable income for the year will be
taxable as ordinary income. Distributions designated as derived from a
Portfolio's dividend income, if any, that would be eligible for the dividends
received deduction if such Portfolio's were not a regulated investment company
may be eligible for the dividends-received deduction for corporate shareholders.
The dividends-received deduction, if available, is reduced to the extent the
shares with respect to which the dividends are received are treated as
debt-financed under federal income tax law and is eliminated if the shares are
deemed to have been held for less than a minimum period, generally 46 days. The
entire dividend, including the deducted amount, is considered in determining the
excess, if any, of a corporate shareholder's adjusted current earnings over its
alternative minimum taxable income, which may increase its liability for the
federal alternative minimum tax, and the dividend may, if it is treated as an
"extraordinary dividend" under the Code, reduce such shareholder's tax basis in
its shares of a Portfolio. Capital gain dividends (i.e., dividends from net
capital gain), if designated as such in a written notice to shareholders mailed
not later than 60 days after a Portfolio's taxable year closes, will be taxed to
shareholders as long-term capital gain regardless of how long shares have been
held by shareholders, but are not eligible for the dividends-received deduction
for corporations. Such long-term capital gain will generally be 20% rate gain.
Distributions, if any, that are in excess of a Portfolio's current and
accumulated earnings and profits will first reduce a shareholder's tax basis in
his shares and, after such basis is reduced to zero, will generally constitute
capital gains to a shareholder who holds his shares as capital assets.

      Different tax treatment, including penalties on certain excess
contributions and deferrals, certain pre-retirement and post-retirement
distributions and certain prohibited 


                                      B-99
<PAGE>
 
transactions, is accorded to accounts maintained as qualified retirement plans.
Shareholders should consult their tax advisers for more information.

Taxable U.S. Shareholders - Sale of Shares

      When a shareholder's shares are sold, redeemed or otherwise disposed of in
a transaction that is treated as a sale for tax purposes, the shareholder will
generally recognize gain or loss equal to the difference between the
shareholder's adjusted tax basis in the shares and the cash, or fair market
value of any property, received. Assuming the shareholder holds the shares as a
capital asset at the time of such sale, such gain or loss should be capital in
character, and long-term if the shareholder has a tax holding period for the
shares of more than one year, otherwise short-term. In general, the maximum
long-term capital gain rate will be 20% for gains on assets held more than one
year. Shareholders should consult their own tax advisers with reference to their
particular circumstances to determine whether a redemption (including an
exchange) or other disposition of Portfolio shares is properly treated as a sale
for tax purposes, as is assumed in this discussion. If a shareholder receives a
capital gain dividend with respect to shares and such shares have a tax holding
period of six months or less at the time of a sale or redemption of such shares,
then any loss the shareholder realizes on the sale or redemption will be treated
as a long-term capital loss to the extent of such capital gain dividend. All or
a portion of any sales load paid upon the purchase of shares of a Portfolio will
not be taken into account in determining gain or loss on the redemption or
exchange of such shares within 90 days after their purchase to the extent the
redemption proceeds are reinvested, or the exchange is effected, without payment
of an additional sales load pursuant to the reinvestment or exchange privilege.
The load not taken into account will be added to the tax basis of the newly
acquired shares. Additionally, any loss realized on a sale or redemption of
shares of a Portfolio may be disallowed under "wash sale" rules to the extent
the shares disposed of are replaced with other shares of the same Portfolio
within a period of 61 days beginning 30 days before and ending 30 days after the
shares are disposed of, such as pursuant to a dividend reinvestment in shares of
such Portfolio. If disallowed, the loss will be reflected in an adjustment to
the basis of the shares acquired.

      Each Portfolio may be required to withhold, as "backup withholding,"
federal income tax at a rate of 31% from dividends (including capital gain
dividends) and share redemption and exchange proceeds to individuals and other
non-exempt shareholders who fail to furnish such Portfolio with a correct
taxpayer identification number ("TIN") certified under penalties of perjury, or
if the Internal Revenue Service or a broker notifies the Portfolio that the
payee is subject to backup withholding as a result of failing to properly report
interest or dividend income to the Internal Revenue Service or that the TIN
furnished by the payee to the Portfolio is incorrect, or if (when required to do
so) the payee fails to certify under penalties of perjury that it is not subject
to backup withholding. A Portfolio may refuse to accept an application that does
not contain any required TIN or certification that the TIN provided is correct.
If the backup withholding provisions are applicable, any such dividends and
proceeds, whether paid in cash or reinvested in additional shares, will be
reduced by the amounts required to be withheld. Any amounts withheld may be
credited against a shareholder's U.S. federal income tax liability. If you do
not have a TIN, you should apply for one immediately by contacting your local
office of the Social Security Administration or the Internal Revenue Services.
Backup withholding could apply to payments relating to your account while you
are waiting receipt of a TIN. Special rules apply for certain entities. For


                                     B-100
<PAGE>
 
example, for an account established under a Uniform Gifts for Transfer to Minors
Act, the TIN of the minor should be furnished.

Non-U.S. Shareholders

      The discussion above relates solely to U.S. federal income tax law as it
applies to "U.S. persons" subject to tax under such law. Shareholders who, as to
the United States, are not "U.S. persons" (i.e., are nonresident aliens, foreign
corporations, fiduciaries of foreign trusts or estates, foreign partnerships or
other non-U.S. investors) generally will be subject to U.S. federal withholding
tax at the rate of 30% on distributions treated as ordinary income unless the
tax is reduced or eliminated pursuant to a tax treaty or the dividends are
effectively connected with a U.S. trade or business of the shareholder. In the
latter case the dividends will be subject to tax on a net income basis at the
graduated rates applicable to U.S. individuals or domestic corporations.
Distributions of net capital gain, including amounts retained by a Portfolio
which are designated as undistributed capital gains, to a non-U.S. shareholder
will not be subject to U.S. federal income or withholding tax unless the
distributions are effectively connected with the shareholder's trade or business
in the United States or, in the case of a shareholder who is a nonresident alien
individual, the shareholder is present in the United States for 183 days or more
during the taxable year and certain other conditions are met.

      Any capital gain realized by a non-U.S. shareholder upon a sale or
redemption of shares of a Portfolio will not be subject to U.S. federal income
or withholding tax unless the gain is effectively connected with the
shareholder's trade or business in the U.S., or in the case of a shareholder who
is a nonresident alien individual, the shareholder is present in the U.S. for
183 days or more during the taxable year and certain other conditions are met.

      Non-U.S. persons who fail to furnish a Portfolio with an IRS Form W-8 or
an acceptable substitute may be subject to backup withholding at the rate of 31%
on capital gain dividends and the proceeds of redemptions and exchanges. Each
shareholder who is not a U.S. person should consult his or her tax adviser
regarding the U.S. and non-U.S. tax consequences of ownership of shares of and
receipt of distributions from the Portfolios.

State and Local

      Each Portfolio may be subject to state or local taxes in jurisdictions in
which such Portfolio may be deemed to be doing business. In addition, in those
states or localities which have income tax laws, the treatment of such Portfolio
and its shareholders under such laws may differ from their treatment under
federal income tax laws, and investment in such Portfolio may have tax
consequences for shareholders different from those of a direct investment in the
securities held by the Portfolio. Shareholders should consult their own tax
advisers concerning these matters.

incorporated hereby by reference.

                                OTHER INFORMATION

      Each Portfolio will redeem shares solely in cash up to the lesser of
$250,000 or 1% of the net asset value of the Portfolio during any 90-day period
for any one shareholder. Each Portfolio, however, reserves the right to pay
redemptions exceeding $250,000 or 1% of the net asset value of the Portfolio at
the time of redemption by a distribution in kind of securities (instead of cash)
from such Portfolio. The securities distributed in kind would be readily
marketable and would be valued for this purpose using the same method employed
in calculating the Portfolio's net asset value per share. See "Net Asset Value."
If a shareholder receives redemption proceeds in kind, the shareholder should
expect to incur transaction costs upon the disposition of the securities
received in the redemption.

      The right of a shareholder to redeem shares and the date of payment by
each Portfolio may be suspended for more than seven days for any period during
which the New York Stock Exchange is closed, other than the customary weekends
or holidays, or when trading on such Exchange is restricted as determined by the
SEC; or during any emergency, as determined by the SEC, as a result of which it
is not reasonably practicable for such Portfolio to dispose of securities owned
by it or fairly 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 of such
Portfolio. (The Trust may also suspend or postpone the recordation of the
transfer of shares upon the occurrence of any of the foregoing conditions.)

      The Prospectus and this Additional Statement do not contain all the
information included in the Registration Statement filed with the SEC under the
1933 Act with respect to the securities offered by the Prospectus. Certain
portions of the Registration Statement have been omitted from the Prospectus and

redemption and exchange orders placed by or on behalf of their customers and, if
approved by the Trust, to designate other intermediaries to accept such orders.
These institutions may receive payments from the Trust or Goldman Sachs for
their services. In some, but not all, cases these payments will be pursuant to a
Distribution and Service Plan or Service Plan described in the Prospectuses and
the following sections. Certain Service Organizations or institutions may enter
into sub-transfer agency agreements with the Trust or Goldman Sachs with respect
to their services.

      The Adviser, Distributor and/or their affiliates may pay, out of their own
assets, compensation to Authorized Dealers, Service Organizations and other
financial intermediaries ("Intermediaries") for the sale and distribution of
shares of the Portfolios and/or for the servicing of those shares. These
payments ("Additional Payments") would be in addition to the payments by the
Portfolios described in the Portfolios' Prospectus and this Additional Statement
for distribution and shareholder servicing and processing, and would also be in
addition to the sales commissions payable to Intermediaries as set forth in the
Prospectus. These Additional Payments may take the form of "due diligence"
payments for an Intermediary's examination of the Portfolios and payments for
providing extra employee training and information relating to the Portfolios;
"listing" fees for the placement of the Portfolios on an Intermediary's list of
mutual funds available for purchase by its customers; "finders" or "referral"
fees for directing investors to the Portfolios; "marketing support" fees for
providing assistance in promoting the sale of the Portfolios' shares; and
payments for the sale of Shares and/or the maintenance of share balances. In
addition, the Adviser, Distributor and/or their affiliates may make Additional
Payments for subaccounting, administrative and/or shareholder processing
services that are in addition to the shareholder servicing and processing fees
paid by the Portfolios. The Additional Payments made by the Adviser, Distributor
and their affiliates may be a fixed dollar amount, may be based on the number of
customer accounts maintained by an Intermediary, or may be based on a percentage
of the value of shares sold to, or held by, customers of the Intermediary
involved, and may be different for different Intermediaries. Furthermore, the
Adviser, Distributor and/or their affiliates may contribute to various non-cash
and cash incentive arrangements to promote the sale of shares, as well as
sponsor various educational programs, sales contests and/or promotions. The
Adviser, Distributor and their affiliates may also pay for the travel expenses,
meals, lodging and entertainment of Intermediaries and their salespersons and
guests in connection with educational, sales and promotional programs subject to
applicable NASD regulations. The Distributor currently expects that such
additional bonuses or incentives will not exceed 0.50% of the amount of any
sales.

Other Purchase Information

      The sales load waivers on the Portfolios' shares are due to the nature of
the investors involved and/or the reduced sales effort that is needed to obtain
such investments.

      If shares of a Portfolio are held in a "street name" account with an
Authorized Dealer, all recordkeeping, transaction processing and payments of
distributions relating to the beneficial owner's account will be performed by
the Authorized Dealer, and not by a Portfolio and its Transfer Agent. Since the
Portfolios will have no record of the beneficial owner's transactions, a
beneficial owner should contact the Authorized Dealer to purchase, redeem or
exchange shares, to make changes in or give instructions concerning the account
or to obtain information about the account. The transfer of shares in a "street
name" account to an account with another dealer or to an account directly with a
Portfolio involves special procedures and will require the beneficial owner to
obtain historical purchase information about the shares in the account from the
Authorized Dealer.

      Authorized Dealers and other financial intermediaries provide varying
arrangements for their clients to purchase and redeem Portfolio shares. Some may
establish higher minimum investment requirements and others may limit the
availability of certain privileges with respect to the purchase and redemption
of shares or the reinvestment of dividends. Firms may arrange with their clients
for other investment or administrative services and may independently establish
and charge additional amounts to their clients for such services, which charges
would reduce a client's return.

Right of Accumulation - (Class A)

      A Class A shareholder qualifies for cumulative quantity discounts if the
current purchase price of the new investment plus the shareholder's current
holdings of existing Class A Shares (acquired by purchase or exchange) of the
Portfolios and Class A Shares of any other Goldman Sachs Fund (as defined in the
Prospectus) total the requisite amount for receiving a discount. For example, if
a shareholder owns shares with a current market value of $65,000 and purchases
additional Class A Shares of the Balanced Strategy Portfolio with a purchase
price of $45,000, the sales charge for the $45,000 purchase would be 3.0% (the
rate applicable to a single purchase of more than $100,000). Class A Shares
purchased without the imposition of a sales charge and shares of another class
of the Portfolios may not be aggregated with Class A Shares purchased subject to
a sales charge. Class A Shares of the Portfolios and any other Goldman Sachs
Fund purchased (i) by an individual, his spouse and his children, and (ii) by a
trustee, guardian or other fiduciary of a single trust estate or a single
fiduciary account, will be combined for the purpose of determining whether a
purchase will qualify for such right of accumulation and, if qualifying, the
applicable sales charge level. For purposes of applying the right of
accumulation, shares of the Portfolios and any other Goldman Sachs Fund
purchased by an existing client of the Private Client Services Division of
Goldman Sachs will be combined with Class A Shares held by any other Private
Client Services account. In addition, Class A Shares of 


                                     B-104
<PAGE>
 
the Portfolios and Class A Shares of any other Goldman Sachs Fund purchased by
partners, directors, officers or employees of the same business organization or
by groups of individuals represented by and investing on the recommendation of
the same accounting firm, certain affinity groups or other similar organizations
(collectively, "eligible persons") may be combined for the purpose of
determining whether a purchase will qualify for the right of accumulation and,
if qualifying, the applicable sales charge level. This right of accumulation is
subject to the following conditions: (i) the business organization's, group's or
firm's agreement to cooperate in the offering of the Portfolios' shares to
eligible persons; and (ii) notification to the Portfolios at the time of
purchase that the investor is eligible for this right of accumulation.

Statement of Intention - (Class A)

      If a shareholder anticipates purchasing at least $100,000 of Class A
Shares of a Portfolio alone or in combination with Class A Shares of any other
Goldman Sachs Fund within a 13-month period, the shareholder may purchase shares
of the Portfolio at a reduced sales charge by submitting a Statement of
Intention (the "Statement"). Shares purchased pursuant to a Statement will be
eligible for the same sales charge discount that would have been available if
all of the purchases had been made at the same time. The shareholder or his or
her Authorized Dealer must inform Goldman Sachs that the Statement is in effect
each time shares are purchased. There is no obligation to purchase the full
amount of shares indicated in the Statement. A shareholder may include the value
of all Class A Shares on which a sales charge has previously been paid as an
"accumulation credit" toward the completion of the Statement, but a price
readjustment will be made only on Class A Shares purchased within ninety (90)
days before submitting the Statement. The Statement authorizes the Transfer
Agent to hold in escrow a sufficient number of shares which can be redeemed to
make up any difference in the sales charge on the amount actually invested. For
purposes of satisfying the amount specified on the Statement, the gross amount
of each investment, exclusive of any appreciation on shares previously
purchased, will be taken into account.

      The provisions applicable to the Statement, and the terms of the related
escrow agreement, are set forth in Appendix C to this Additional Statement.

Cross-Reinvestment of Dividends and Distributions

      You may receive dividends and distributions in additional shares of the
same class of the Portfolio in which you have invested or you may elect to
receive them in cash or shares of the same class of other mutual funds sponsored
by Goldman Sachs (the "Goldman Sachs Funds") or ILA Service Units of the Prime
Obligations Portfolio or the Tax-Exempt Diversified Portfolio, if you hold Class
A Shares of a Portfolio, or ILA Class B or Class C Units of the Prime
Obligations Portfolio, if you hold Class B or Class C Shares of a Portfolio (the
"ILA Portfolios").

      A Portfolio shareholder should obtain and read the prospectus relating to
any other Goldman Sachs Fund or ILA Portfolio (as defined in the Prospectus) and
its shares or units and consider its investment objective, policies and
applicable fees before electing cross-reinvestment into that Fund or Portfolio.
The election to cross-reinvest dividends and capital gain distributions will not
affect the tax treatment of such dividends and distributions, which will be
treated as received by the shareholder and then used to purchase shares of the
acquired fund. Such reinvestment of dividends and distributions in shares of
other Goldman Sachs Funds or in units of ILA Portfolios is available only in
states where such reinvestment may legally be made.

Automatic Exchange Program

      A Portfolio shareholder may elect to exchange automatically a specified
dollar amount of shares of a Portfolio into an identical account or an account
registered in a different name or with a different address, social security or
other taxpayer identification number, provided that the account in the acquired
fund has been established, appropriate signatures have been obtained and the
minimum initial investment requirement has been satisfied. A Portfolio
shareholder should obtain and read the prospectus relating to any other Goldman
Sachs Fund and its shares and consider its investment objective, policies and
applicable fees and expenses before electing an automatic exchange into that
Goldman Sachs Fund.

Systematic Withdrawal Plan

      A systematic withdrawal plan (the "Systematic Withdrawal Plan") is
available to shareholders of a Portfolio whose shares are worth at least $5,000.
The Systematic Withdrawal Plan provides for monthly payments to the
participating shareholder of any amount not less than $50.

      Dividends and capital gain distributions on shares held under the
Systematic Withdrawal Plan are reinvested in additional full and fractional
shares of the applicable Portfolio at net asset value. The Transfer Agent acts
as agent for the shareholder in redeeming sufficient full and fractional shares
to provide the amount of the systematic withdrawal payment. The Systematic
Withdrawal Plan may be terminated at any time. Goldman Sachs reserves the right
to initiate a fee of up to $5 per withdrawal, upon thirty (30) days written
notice to the shareholder. Withdrawal payments should not be considered to be
dividends, yield or income. If periodic withdrawals continuously exceed new
purchases and reinvested dividends and capital gains distributions, the
shareholder's original investment will be correspondingly reduced and ultimately
exhausted. The maintenance of a withdrawal plan concurrently with purchases of
additional Class A, Class B or Class C Shares would be disadvantageous because
of the sales charge imposed on purchases of Class A Shares or the imposition of
a CDSC on redemptions of Class A, Class B and Class C Shares. The CDSC
applicable to Class B and Class C Shares redeemed under a systematic withdrawal
plan may be waived. See "Shareholder Guide" in the Prospectus. In addition, each
withdrawal constitutes a redemption of shares, and any gain or loss realized
must be reported for federal and state income tax purposes. A shareholder should
consult his or her own tax adviser with regard to the tax consequences of
participating in the Systematic Withdrawal Plan. For further information or to
request a Systematic Withdrawal Plan, please write or call the Transfer Agent.

                         DISTRIBUTION AND SERVICE PLANS
                   (Class A, Class B and Class C Shares Only)

      As described in the Prospectus, the Trust has adopted, on behalf of Class
A, Class B and Class C Shares of each Portfolio, distribution and service plans
(each a "Plan") pursuant to Rule 12b-1 under the Act.

      The Plans for each Portfolio were most recently approved on April 27, 1999
by a majority vote of the Trustees of the Trust, including a majority of the
non-interested Trustees of 


                                     B-106
<PAGE>
 
the Trust who have no direct or indirect financial interest in the Plans, cast
in person at a meeting called for the purpose of approving the Plans.

      The compensation for distribution services payable under a Plan may not
exceed 0.25%, 0.75% and 0.75% per annum of a Portfolio's average daily net
assets attributable to Class A, Class B and Class C Shares, respectively, of
such Portfolio. Under the Plans for Class B and Class C Shares, Goldman Sachs is
also entitled to receive a separate fee for personal and account maintenance
services equal to an annual basis of 0.25% of each Portfolio's average daily net
assets attributable to Class B or Class C Shares. With respect to Class A
Shares, the Distributor at its discretion may use compensation for distribution
services paid under the Plan for personal and account maintenance services and
expenses so long as such total compensation under the Plan does not exceed the
maximum cap on "service fees" imposed by the NASD.

      Each Plan is a compensation plan which provides for the payment of a
specified fee without regard to the expenses actually incurred by Goldman Sachs.
If such fee exceeds Goldman Sachs' expenses, Goldman Sachs may realize a profit
from these arrangements. The distribution fees received by Goldman Sachs under
the Plans and contingent deferred sales charge on Class A, Class B and Class C
Shares may be sold by Goldman Sachs as distributor to entities which provide
financing for payments to Authorized Dealers in respect of sales of Class A,
Class B and Class C Shares. To the extent such fees are not paid to such
dealers, Goldman Sachs may retain such fee as compensation for its services and
expenses of distributing the Portfolios' Class A, Class B and Class C Shares.

      Under each Plan, Goldman Sachs, as distributor of each Portfolio's Class
A, Class B and Class C Shares, will provide to the Trustees of the Trust for
their review, and the Trustees of the Trust will review at least quarterly a
written report of the services provided and amounts expended by Goldman Sachs
under the Plans and the purposes for which such services were performed and
expenditures were made.

      The Plans will remain in effect until May 1, 2000 and from year to year
thereafter, provided that such continuance is approved annually by a majority
vote of the Trustees of the Trust, including a majority of the non-interested
Trustees of the Trust who have no direct or indirect financial interest in the
Plans. The Plans may not be amended to increase materially the amount of
distribution compensation described therein without approval of a majority of
the outstanding Class A, Class B or Class C Shares of the affected Portfolio and
share class. All material amendments of a Plan must also be approved by the
Trustees of the Trust in the manner described above. A Plan may be terminated at
any time as to any Portfolio without payment of any penalty by a vote of a
majority of the non-interested Trustees of the Trust or by vote of a majority of
the outstanding Class A, Class B or Class C Shares, respectively, of the
applicable Portfolio and share class. If a Plan was terminated by the Trustees
of the Trust and no successor plan was adopted, the Portfolio would cease to
make payments to Goldman Sachs under the Plan and Goldman Sachs would be unable
to recover the amount of any of its unreimbursed expenditures. So long as a Plan
is in effect, the selection and nomination of non-interested Trustees of the
Trust will be committed to the discretion of the non-interested Trustees of the
Trust. The Trustees of the Trust have determined that in their judgment there is
a reasonable likelihood that the Plans will benefit the Portfolios and their
Class A, Class B and Class C Shareholders.

      The foregoing tables reflect amount expended by Goldman Sachs, which
amounts are in excess of the compensation received by Goldman Sachs under the
Plants. The payments under the Plans were used by Goldman Sachs to compensate it
for the expenses shown above on a pro-rate basis.

      Each Portfolio has adopted a service plan (the "Plan") with respect to its
Service Shares which authorizes it to compensate Service Organizations for
providing certain administration services and personal and account maintenance
services to their customers who are or may become beneficial owners of such
Shares. Pursuant to the Plan, a Portfolio will enter into agreements with
Service Organizations which purchase Service Shares of the Portfolio on behalf
of their customers ("Service Agreements"). Under such Service Agreements the
Service Organizations may perform some or all of the following services: (a)
act, directly or through an agent, as the sole shareholder of record and nominee
for all customers, (b) maintain account records for each customer who
beneficially owns Service Shares of a Portfolio, (c) answer questions and handle
correspondence from customers regarding their accounts, (d) process customer
orders to purchase, redeem and exchange Service Shares of a Portfolio, and
handle the transmission of funds representing the customers' purchase price or
redemption proceeds, (e) issue confirmations for transactions in shares by
customers, (f) provide facilities to answer questions from prospective and
existing investors about Service Shares of a Portfolio, (g) receive and answer
investor correspondence, including requests for prospectuses and statements of
additional information, (h) display and make prospectuses available on the
Service Organization's premises, (i) assist customers in completing application
forms, selecting dividend and other account options and opening custody accounts
with the Service Organization and (j) act as liaison between customers and a
Portfolio, including obtaining information from a Portfolio, working with a
Portfolio to correct errors and resolve problems and providing statistical and
other information to a Portfolio. As compensation for such services, a Portfolio
will pay each Service Organization a service fee in an amount up to 0.50% (on an
annualized basis) of the average daily net assets of the Service Shares of such
Portfolio attributable to or held in the name of such Service Organization;
provided, however, that the fee paid for personal and account maintenance
services shall not exceed 0.25% such average daily net assets.

      The amount of the service fees paid by each Portfolio then in existence to
Service Organizations was as follows for the period ended December 31:

      Each Portfolio has adopted its Plan pursuant to Rule 12b-1 under the 1940
Act in order to avoid any possibility that payments to the Service Organizations
pursuant to the Service Agreements might violate the 1940 Act. Rule 12b-1, which
was adopted by the SEC under the Act, regulates the circumstances under which an
investment company or series thereof may bear expenses associated with the
distribution of its shares. In particular, such an investment company or series
thereof cannot engage directly or indirectly in financing any activity which is
primarily intended to result in the sale of shares issued by the company unless
it has adopted a plan pursuant to, and complies with the other requirements of,
such Rule. The Trust believes that fees paid for the services provided in the
Plan and described above are not expenses incurred primarily for effecting the
distribution of Service Shares. However, should such payments be deemed by a
court or the SEC to be distribution expenses, such payments would be duly
authorized by the Plan.

      The Glass-Steagall Act prohibits all entities which receive deposits from
engaging to any extent in the business of issuing, underwriting, selling or
distributing securities, although institutions such as national banks are
permitted to purchase and sell securities upon the order and for the account of
their customers. In addition, under some state securities laws, banks and other
financial institutions purchasing Service Shares on behalf of their customers
may be required to register as dealers. Should future legislative or
administrative action or judicial or administrative decisions or interpretations
prohibit or restrict the activities of one or more of the Service Organizations
in connection with the Portfolios, such Service Organizations might be required
to alter materially or discontinue the services performed under their Service
Agreements. If one or more of the Service Organizations were restricted from
effecting purchases or sales of Service Shares automatically pursuant to
pre-authorized instructions, for example, effecting such transactions on a
manual basis might affect the size and/or growth of a Portfolio. Any such
alteration or discontinuance of services could require the Board of Trustees to
consider changing a Portfolio's method of operations or providing alternative
means of offering Service Shares of a Portfolio to customers of such Service
Organizations, in which case the operation of such Portfolio, its size and/or
its growth might be significantly altered. It is not anticipated, however, that
any alteration of a Portfolio's operations would have any effect on the net
asset value per share or result in financial losses to any shareholder.

      Conflict of interest restrictions (including the Employee Retirement
Income Security Act of 1974) may apply to a Service Organization's receipt of
compensation paid by a Portfolio in connection with the investment of fiduciary
assets in Service Shares of such Portfolio. Service Organizations, including
banks regulated by the Comptroller of the Currency, the Federal Reserve Board or
the Federal Deposit Insurance Corporation, and investment advisers and other
money managers subject to the jurisdiction of the SEC, the Department of Labor
or state securities regulators, are urged to consult their legal advisers before
investing fiduciary assets in Service Shares of the Portfolios. In addition,
under some state securities laws, banks and other financial institutions
purchasing Service Shares on behalf of their customers may be required to
register as dealers.

      The Trustees, including a majority of the Trustees who are not interested
persons of the Trust and who have no direct or indirect financial interest in
the operation of the Plan or the related Service Agreements, most recently voted
to approve each Portfolio's Plan and related Service Agreements at a meeting
called for the purpose of voting on such Plan and Service Agreements on April
27, 1999. The Plan and Service Agreements will remain in effect until May 1,
2000 and will continue in effect thereafter only if such continuance is
specifically 


                                     B-113

approved annually by a vote of the Board of Trustees in the manner described
above. The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval of the Service Shareholders
of the affected Portfolio, and all material amendments of the Plan must also be
approved by the Board of Trustees in the manner described above. The Plan may be
terminated at any time by a majority of the Board of Trustees as described above
or by vote of a majority of the outstanding Service Shares of the affected
Portfolio. The Service Agreements may be terminated at any time, without payment
of any penalty, by vote of a majority of the Board of Trustees as described
above or by a vote of a majority of the outstanding Service Shares of the
affected Portfolio on not more than sixty (60) days' written notice to any other
party to the Service Agreements. The Service Agreements will terminate
automatically if assigned. So long as the Plan is in effect, the selection and
nomination of those Trustees who are not interested persons will be committed to
the discretion of the Trust's Nominating Committee, which consists of all of the
non-interested members of the Board of Trustees. The Board of Trustees has
determined that, in its judgment, there is a reasonable likelihood that a
Portfolio's Plan will benefit such Portfolio and its holders of Service Shares.

Commercial Paper Ratings

            A Standard & Poor's ("S&P") commercial paper rating is a current
assessment of the likelihood of timely payment of debt having an original
maturity of no more than 365 days. The following summarizes the rating
categories used by Standard and Poor's for commercial paper:

            "A-1" - Obligations are rated in the highest category indicating
that the obligor's capacity to meet its financial commitment on the obligation
is strong. Within this category, certain obligations are designated with a plus
sign (+). This indicates that the obligor's capacity to meet its financial
commitment on these obligations is extremely strong.

            "A-2" - Obligations are somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

            "A-3" - Obligations exhibit adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.

            "B" - Obligations are regarded as having significant speculative
characteristics. The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

            "C" - Obligations are currently vulnerable to nonpayment and are
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.

            "D" - Obligations are in payment default. The "D" rating category is
used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless S&P believes that such payments
will be made during such grace period. The "D" rating will be used upon the
filing of a bankruptcy petition or the taking of a similar action if payments on
an obligation are jeopardized.

            Moody's commercial paper ratings are opinions of the ability of
issuers to repay punctually senior debt obligations not having an original
maturity in excess of one year, unless explicitly noted. The following
summarizes the rating categories used by Moody's for commercial paper:

            "Prime-1" - Issuers (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:
leading market positions in well-established industries; high rates of return on
funds employed; conservative capitalization structure with moderate reliance on
debt and ample asset protection; broad margins in earnings coverage of fixed
financial charges and high internal cash generation; and well-established access
to a range of financial markets and assured sources of alternate liquidity.


                                      1-A
<PAGE>
 
            "Prime-2" - Issuers (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

            "Prime-3" - Issuers (or supporting institutions) have an acceptable
ability for repayment of senior short-term debt obligations. The effect of
industry characteristics and market compositions may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.

            "Not Prime" - Issuers do not fall within any of the Prime rating
categories.

            The three rating categories of Duff & Phelps for investment grade
commercial paper and short-term debt are "D-1," "D-2" and "D-3." Duff & Phelps
employs three designations, "D-1+," "D-1" and "D-1-," within the highest rating
category. The following summarizes the rating categories used by Duff & Phelps
for commercial paper:

            "D-1+" - Debt possesses the highest certainty of timely payment.
Short-term liquidity, including internal operating factors and/or access to
alternative sources of funds, is outstanding, and safety is just below risk-free
U.S. Treasury short-term obligations.

            "D-1" - Debt possesses very high certainty of timely payment.
Liquidity factors are excellent and supported by good fundamental protection
factors. Risk factors are minor.

            "D-1-" - Debt possesses high certainty of timely payment. Liquidity
factors are strong and supported by good fundamental protection factors. Risk
factors are very small.

            "D-2" - Debt possesses good certainty of timely payment. Liquidity
factors and company fundamentals are sound. Although ongoing funding needs may
enlarge total financing requirements, access to capital markets is good. Risk
factors are small.

            "D-3" - Debt possesses satisfactory liquidity and other protection
factors qualify issues as to investment grade. Risk factors are larger and
subject to more variation. Nevertheless, timely payment is expected.

            "D-4" - Debt possesses speculative investment characteristics.
Liquidity is not sufficient to insure against disruption in debt service.
Operating factors and market access may be subject to a high degree of
variation.

            "D-5" - Issuer has failed to meet scheduled principal and/or
interest payments.

            Fitch IBCA short-term ratings apply to debt obligations that have
time horizons of less than 12 months for most obligations, or up to three years
for U.S. public finance securities. The following summarizes the rating
categories used by Fitch IBCA for short-term obligations:


                                      2-A
<PAGE>
 
            "F1" - Securities possess the highest credit quality. This
designation indicates the strongest capacity for timely payment of financial
commitments and may have an added "+" to denote any exceptionally strong credit
feature.

            "F2" - Securities possess good credit quality. This designation
indicates a satisfactory capacity for timely payment of financial commitments,
but the margin of safety is not as great as in the case of the higher ratings.

            "F3" - Securities possess fair credit quality. This designation
indicates that the capacity for timely payment of financial commitments is
adequate; however, near-term adverse changes could result in a reduction to
non-investment grade.

            "B" - Securities possess speculative credit quality. This
designation indicates minimal capacity for timely payment of financial
commitments, plus vulnerability to near-term adverse changes in financial and
economic conditions.

            "C" - Securities possess high default risk. This designation
indicates that default is a real possibility and that the capacity for meeting
financial commitments is solely reliant upon a sustained, favorable business and
economic environment.

            "D" - Securities are in actual or imminent payment default.

            Thomson BankWatch short-term ratings assess the likelihood of an
untimely payment of principal and interest of debt instruments with original
maturities of one year or less. The following summarizes the ratings used by
Thomson BankWatch:

            "TBW-1" - This designation represents Thomson BankWatch's highest
category and indicates a very high likelihood that principal and interest will
be paid on a timely basis.

            "TBW-2" - This designation represents Thomson BankWatch's
second-highest category and indicates that while the degree of safety regarding
timely repayment of principal and interest is strong, the relative degree of
safety is not as high as for issues rated "TBW-1."

            "TBW-3" - This designation represents Thomson BankWatch's lowest
investment-grade category and indicates that while the obligation is more
susceptible to adverse developments (both internal and external) than those with
higher ratings, the capacity to service principal and interest in a timely
fashion is considered adequate.

            "TBW-4" - This designation represents Thomson BankWatch's lowest
rating category and indicates that the obligation is regarded as non-investment
grade and therefore speculative.

Corporate and Municipal Long-Term Debt Ratings

            The following summarizes the ratings used by Standard & Poor's for
corporate and municipal debt:

            "AAA" - An obligation rated "AAA" has the highest rating assigned by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is extremely strong.


                                      3-A
<PAGE>
 
            "AA" - An obligation rated "AA" differs from the highest rated
obligations only in small degree. The obligor's capacity to meet its financial
commitment on the obligation is very strong.

            "A" - An obligation rated "A" is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher-rated categories. However, the obligor's capacity to meet
its financial commitment on the obligation is still strong.

            "BBB" - An obligation rated "BBB" exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

            Obligations rated "BB," "B," "CCC," "CC" and "C" are regarded as
having significant speculative characteristics. "BB" indicates the least degree
of speculation and "C" the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.

            "BB" - An obligation rated "BB" is less vulnerable to nonpayment
than other speculative issues. However, it faces major ongoing uncertainties or
exposure to adverse business, financial or economic conditions which could lead
to the obligor's inadequate capacity to meet its financial commitment on the
obligation.

            "B" - An obligation rated "B" is more vulnerable to nonpayment than
obligations rated "BB", but the obligor currently has the capacity to meet its
financial commitment on the obligation. Adverse business, financial or economic
conditions will likely impair the obligor's capacity or willingness to meet its
financial commitment on the obligation.

            "CCC" - An obligation rated "CCC" is currently vulnerable to
nonpayment, and is dependent upon favorable business, financial and economic
conditions for the obligor to meet its financial commitment on the obligation.
In the event of adverse business, financial, or economic conditions, the obligor
is not likely to have the capacity to meet its financial commitment on the
obligation.

            "CC" - An obligation rated "CC" is currently highly vulnerable to
nonpayment.

            "C" - The "C" rating may be used to cover a situation where a
bankruptcy petition has been filed or similar action has been taken, but
payments on this obligation are being continued.

            "D" - An obligation rated "D" is in payment default. The "D" rating
category is used when payments on an obligation are not made on the date due
even if the applicable grace period has 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 or the taking of a similar action
if payments on an obligation are jeopardized.

            PLUS (+) OR MINUS (-) - The ratings from "AA" through "CCC" may be
modified by the addition of a plus or minus sign to show relative standing
within the major rating categories.

            "r" - This symbol is attached to the ratings of instruments with
significant noncredit risks. It highlights risks to principal or volatility of
expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations 


                                      4-A
<PAGE>
 
exposed to severe prepayment risk - such as interest-only or principal-only
mortgage securities; and obligations with unusually risky interest terms, such
as inverse floaters.

      The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt:

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

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

            "A" - Bonds 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.

            "Baa" - Bonds 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.

            "Ba," "B," "Caa," "Ca" and "C" - Bonds that possess one of these
ratings provide questionable protection of interest and principal ("Ba"
indicates speculative elements; "B" indicates a general lack of characteristics
of desirable investment; "Caa" are of poor standing; "Ca" represents obligations
which are speculative in a high degree; and "C" represents the lowest rated
class of bonds). "Caa," "Ca" and "C" bonds may be in default.

            Con. (---) - Bonds for which the security depends upon the
completion of some act or the fulfillment of some condition are rated
conditionally. These are bonds secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operating experience, (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

            Note: Moody's applies numerical modifiers 1, 2, and 3 in each
generic rating classification from "Aa" through "Caa". The modifier 1 indicates
that the obligation ranks in the higher end of its generic rating category; the
modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking
in the lower end of its generic rating category.


                                      5-A
<PAGE>
 
            The following summarizes the long-term debt ratings used by Duff &
Phelps for corporate and municipal long-term debt:

            "AAA" - Debt is considered to be of the highest credit quality. The
risk factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

            "AA" - Debt is considered to be of high credit quality. Protection
factors are strong. Risk is modest but may vary slightly from time to time
because of economic conditions.

            "A" - Debt possesses protection factors which are average but
adequate. However, risk factors are more variable in periods of greater economic
stress.

            "BBB" - Debt possesses below-average protection factors but such
protection factors are still considered sufficient for prudent investment.
Considerable variability in risk is present during economic cycles.

            "BB," "B," "CCC," "DD" and "DP" - Debt that possesses one of these
ratings is considered to be below investment grade. Although below investment
grade, debt rated "BB" is deemed likely to meet obligations when due. Debt rated
"B" possesses the risk that obligations will not be met when due. Debt rated
"CCC" is well below investment grade and has considerable uncertainty as to
timely payment of principal, interest or preferred dividends. Debt rated "DD" is
a defaulted debt obligation, and the rating "DP" represents preferred stock with
dividend arrearages.

            To provide more detailed indications of credit quality, the "AA,"
"A," "BBB," "BB" and "B" ratings may be modified by the addition of a plus (+)
or minus (-) sign to show relative standing within these major categories.

            The following summarizes the ratings used by Fitch IBCA for
corporate and municipal bonds:

            "AAA" - Bonds considered to be investment grade and of the highest
credit quality. These ratings denote the lowest expectation of credit risk and
are assigned only in case of exceptionally strong capacity for timely payment of
financial commitments. This capacity is highly unlikely to be adversely affected
by foreseeable events.

            "AA" - Bonds considered to be investment grade and of very high
credit quality. These ratings denote a very low expectation of credit risk and
indicate very strong capacity for timely payment of financial commitments. This
capacity is not significantly vulnerable to foreseeable events.

            "A" - Bonds considered to be investment grade and of high credit
quality. These ratings denote a low expectation of credit risk and indicate
strong capacity for timely payment of financial commitments. This capacity may,
nevertheless, be more vulnerable to changes in circumstances or in economic
conditions than is the case for higher ratings.

            "BBB" - Bonds considered to be investment grade and of good credit
quality. These ratings denote that there is currently a low expectation of
credit risk. The capacity for timely payment of financial commitments is
considered adequate, but adverse changes in circumstances and in economic
conditions are more likely to impair this capacity.


                                      6-A
<PAGE>
 
            "BB" - Bonds considered to be speculative. These ratings indicate
that there is a possibility of credit risk developing, particularly as the
result of adverse economic changes over time; however, business or financial
alternatives may be available to allow financial commitments to be met.
Securities rated in this category are not investment grade.

            "B" - Bonds are considered highly speculative. These ratings
indicate that significant credit risk is present, but a limited margin of safety
remains. Financial commitments are currently being met; however, capacity for
continued payment is contingent upon a sustained, favorable business and
economic environment.

            "CCC," "CC," "C" - Bonds have high default risk. Default is a real
possibility, and capacity for meeting financial commitments is solely reliant
upon sustained, favorable business or economic developments. "CC" ratings
indicate that default of some kind appears probable, and "C" ratings signal
imminent default.

            "DDD," "DD" and "D" - Bonds are in default. Securities are not
meeting obligations and are extremely speculative. "DDD" designates the highest
potential for recovery of amounts outstanding on any securities involved and "D"
represents the lowest potential for recovery.

            To provide more detailed indications of credit quality, the Fitch
IBCA ratings from and including "AA" to "B" may be modified by the addition of a
plus (+) or minus (-) sign to show relative standing within these major rating
categories.

            Thomson BankWatch assesses the likelihood of an untimely repayment
of principal or interest over the term to maturity of long term debt and
preferred stock which are issued by United States commercial banks, thrifts and
non-bank banks; non-United States banks; and broker-dealers. The following
summarizes the rating categories used by Thomson BankWatch for long-term debt
ratings:

            "AAA" - This designation indicates that the ability to repay
principal and interest on a timely basis is extremely high.

            "AA" - This designation indicates a very strong ability to repay
principal and interest on a timely basis, with limited incremental risk compared
to issues rated in the highest category.

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

            "BBB" - This designation represents the lowest investment-grade
category and indicates an acceptable capacity to repay principal and interest.
Issues rated "BBB" are more vulnerable to adverse developments (both internal
and external) than obligations with higher ratings.

            "BB," "B," "CCC" and "CC" - These designations are assigned by
Thomson BankWatch to non-investment grade long-term debt. Such issues are
regarded as having speculative characteristics regarding the likelihood of
timely payment of principal and interest. "BB" indicates the lowest degree of
speculation and "CC" the highest degree of speculation.

            "D" - This designation indicates that the long-term debt is in
default.


                                      7-A
<PAGE>
 
            PLUS (+) OR MINUS (-) - The ratings from "AAA" through "CC" may
include a plus or minus sign designation which indicates where within the
respective category the issue is placed.

Municipal Note Ratings

            A Standard and Poor's rating reflects the liquidity concerns and
market access risks unique to notes due in three years or less. The following
summarizes the ratings used by Standard & Poor's Ratings Group for municipal
notes:

            "SP-1" - The issuers of these municipal notes exhibit a strong
capacity to pay principal and interest. Those issues determined to possess very
strong characteristics are given a plus (+) designation.

            "SP-2" - The issuers of these municipal notes exhibit satisfactory
capacity to pay principal and interest, with some vulnerability to adverse
financial and economic changes over the term of the notes.

            "SP-3" - The issuers of these municipal notes exhibit speculative
capacity to pay principal and interest.

            Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade ("VMIG"). Such
ratings recognize the differences between short-term credit risk and long-term
risk. The following summarizes the ratings by Moody's Investors Service, Inc.
for short-term notes:

            "MIG-1"/"VMIG-1" - This designation denotes best quality. There is
present strong protection by established cash flows, superior liquidity support
or demonstrated broad-based access to the market for refinancing.

            "MIG-2"/"VMIG-2" - This designation denotes high quality, with
margins of protection that are ample although not so large as in the preceding
group.

            "MIG-3"/"VMIG-3" - This designation denotes favorable quality, with
all security elements accounted for but lacking the undeniable strength of the
preceding grades. Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.

            "MIG-4"/"VMIG-4" - This designation denotes adequate quality.
Protection commonly regarded as required of an investment security is present
and although not distinctly or predominantly speculative, there is specific
risk.

            "SG" - This designation denotes speculative quality. Debt
instruments in this category lack of margins of protection.

            Fitch IBCA and Duff & Phelps use the short-term ratings described
under Commercial Paper Ratings for municipal notes.

                   BUSINESS PRINCIPLES OF GOLDMAN, SACHS & CO.

      Goldman Sachs is noted for its Business Principles, which guide all of the
firm's activities and serve as the basis for its distinguished reputation among
investors worldwide.

      Our client's interests always come first. Our experience shows that if we
serve our clients well, our own success will follow.

      OUR ASSETS ARE OUR PEOPLE, CAPITAL AND REPUTATION. If any of these is ever
diminished, the last is the most difficult to restore. We are dedicated to 
complying fully with the letter and spirit of the laws, rules and ethical 
principles that govern us. Our continued success depends upon unswerving 
adherence to this standard.

      We take great pride in the professional quality of our work. We have an
uncompromising determination to achieve excellence in everything we undertake.
Though we may be involved in a wide variety and heavy volume of activity, we
would, if it came to a choice, rather be best than biggest.

      We stress creativity and imagination in everything we do. While
recognizing that the old way may still be the best way, we constantly strive to
find a better solution to a client's problems. We pride ourselves on having
pioneered many of the practices and techniques that have become standard in the
industry.

      We make an unusual effort to identify and recruit the very best person for
every job. Although our activities are measured in billions of dollars, we
select our people one by one. In a service business, we know that without the
best people, we cannot be the best firm.

      We offer our people the opportunity to move ahead more rapidly than is
possible at most other places. We have yet to find limits to the responsibility
that our best people are able to assume. Advancement depends solely on ability,
performance and contribution to the Firm's success, without regard to race,
color, religion, sex, age, national origin, disability, sexual orientation, or
any other impermissible criterion or circumstance.

      We stress teamwork in everything we do. While individual creativity is
always encouraged, we have found that team effort often produces the best
results. We have no room for those who put their personal interests ahead of the
interests of the Firm and its clients.

      The dedication of our people to the Firm and the intense effort they give
their jobs are greater than one finds in most other organizations. We think that
this is an important part of our success.

      OUR PROFITS ARE A KEY TO OUR SUCCESS. They replenish our capital and 
attract and keep our best people. It is our practice to share our profits
generously with all who help create them. Profitability is crucial to our
future.

      We consider our size an asset that we try hard to preserve. We want to be
big enough to undertake the largest project that any of our clients could

                                   APPENDIX C

                             Statement of Intention
                       (applicable only to Class A shares)

      If a shareholder anticipates purchasing $50,000 or more of Class A Shares
of a Fund alone or in combination with Class A Shares of another Goldman Sachs
Fund within a 13-month period, the shareholder may obtain shares of the Fund at
the same reduced sales charge as though the total quantity were invested in one
lump sum by checking and filing the Statement of Intention in the Account
Application. Income dividends and capital gain distributions taken in additional
shares will not apply toward the completion of the Statement of Intention.

      To ensure that the reduced price will be received on future purchases, the
investor must inform Goldman Sachs that the Statement of Intention is in effect
each time shares are purchased. Subject to the conditions mentioned below, each
purchase will be made at the public offering price applicable to a single
transaction of the dollar amount specified on the Account Application. The
investor makes no commitment to purchase additional shares, but if the
investor's purchases within 13 months plus the value of shares credited toward
completion do not total the sum specified, the investor will pay the increased
amount of the sales charge prescribed in the Escrow Agreement.

                                Escrow Agreement

      Out of the initial purchase (or subsequent purchases if necessary), 5% of
the dollar amount specified on the Account Application will be held in escrow by
the Transfer Agent in the form of shares registered in the investor's name. All
income dividends and capital gains distributions on escrowed shares will be paid
to the investor or to his or her order. When the minimum investment so specified
is completed (either prior to or by the end of the 13th month), the investor
will be notified and the escrowed shares will be released.

      If the intended investment is not completed, the investor will be asked to
remit to Goldman Sachs any difference between the sales charge on the amount
specified and on the amount actually attained. If the investor does not within
20 days after written request by Goldman Sachs pay such difference in the sales
charge, the Transfer Agent will redeem, pursuant to the authority given by the
investor in the Account Application, an appropriate number of the escrowed
shares in order to realize such difference. Shares remaining after any such
redemption will be released by the Transfer Agent.
