                                 INTRODUCTION

     Goldman Sachs Trust (the "Trust") is an open-end, management investment
company. 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 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
Mid Cap Equity Fund ("Mid Cap Equity Fund"), Goldman Sachs Capital Growth Fund
("Capital Growth 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").

     The Funds, except the European Equity, Japanese Equity, International Small
Cap, CORE Large Cap Growth, CORE International Equity, 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 investment adviser to the
Balanced, Growth and Income, CORE Large Cap Growth, CORE Small Cap Equity, CORE
International Equity, Real Estate Securities, Mid Cap Equity and Small Cap
Equity Funds.  Goldman Sachs Fund Management, L.P., ("GSFM") an affiliate of
Goldman Sachs, serves as 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 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 "Advisers."  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 each Fund will achieve its objective.

                              INVESTMENT POLICIES

     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.

BALANCED FUND
- -------------

     The investment objective of the Balanced Fund is to provide shareholders
with long-term capital growth and current income.  The Balanced Fund seeks to
achieve its investment objective by investing in a balanced portfolio
diversified among both equity and 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 returns relative to a market benchmark, the
Lehman Brothers Aggregate Bond 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.

     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
Adviser de-emphasizes interest rate anticipation by 

                                      B-5
<PAGE>
 
monitoring the duration of the portfolio within a narrow range of the 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.

     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 nationally recognized
statistical rating organizations 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.

CORE U.S. EQUITY, CORE LARGE CAP GROWTH, CORE SMALL CAP EQUITY AND CORE
                                                        ---------------
INTERNATIONAL EQUITY FUNDS
- --------------------------                                 

     Under normal circumstances, these Funds will invest at least 90% of their
total assets in equity securities.

     The investment strategy of the CORE U.S. Equity, CORE Large Cap Growth,
CORE Small Cap Equity and CORE International Equity Funds will be implemented to
the extent it is consistent 

                                      B-6
<PAGE>
 
with maintaining a Fund's qualification as a regulated investment company under
the Internal Revenue Code.

     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. The CORE U.S.
Equity and CORE Large Cap Equity Funds may purchase futures contracts only with
respect to the S&P 500 Index (in the case of CORE U.S. Equity Fund) and a
representative index (in the case of CORE Large Cap Growth Fund) in order to
keep a Fund's effective equity exposure close to 100%.  The CORE Small Cap
Equity and CORE International Equity Funds may purchase other types of futures
contracts as described under "Investment Policies  Futures Contracts and Options
on Futures Contracts."  The other Funds may purchase and sell futures contracts
based on various securities (such as U.S. Government Securities), securities
indicies, foreign currencies and other financial instruments and indicies.  For
example, if cash balances are equal to 10% of the net assets, the Fund may enter
into long futures contracts covering an amount equal to 10% of the Fund's net
assets.  As cash balances fluctuate based on new contributions or withdrawals, a
Fund may enter into additional contracts or close out existing positions.

     THE MULTIFACTOR MODELS.  The Multifactor Models are rigorous computerized
rating systems for evaluating different equity markets, currencies and
individual equity securities according to a variety of investment
characteristics (or factors).  The factors used by the Multifactor Models
incorporate many variables studied by traditional fundamental analysts and cover
measures of value, growth, momentum, risk (e.g. price/earnings ratio, book/price
ratio, growth forecasts, earning estimate revisions, price momentum, volatility
and earnings stability).  All of these factors have been shown to significantly
impact the performance of  the equity securities, currencies and markets they
were designated to forecast.

     Because they include many disparate factors, the Adviser believes that the
Multifactor Models are broader in scope and provide a more thorough evaluation
than most conventional, value-oriented quantitative models.  As a result, the
securities, currencies and markets ranked highest by the Multifactor Models do
not have one dominant investment characteristic (such as a low price/earnings
ratio); rather, such securities or markets possess many different investment
characteristics.  By using a variety of relevant factors to select securities,
currencies or markets, the 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 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.

International Equity Fund
- -------------------------

                                      B-7
<PAGE>
 
     International Equity Fund will seek to achieve its investment objective by
investing primarily in equity and equity-related securities of issuers 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 European."

     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.

     Using the research of Goldman Sachs as well as information gathered from
other sources in Europe and the Asia-Pacific region, the 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 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
- --------------------------

                                      B-8
<PAGE>
 
     Each Fund may, under normal market conditions, invest in corporate debt
obligations, including obligations of industrial, utility and financial issuers.
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 Growth, Mid Cap Equity, 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 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, Mid Cap Equity, 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 

                                      B-9
<PAGE>
 
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 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.

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.  See "Taxation."

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 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 up to 5% of its net assets 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 securities law
purposes, custodial receipts are not considered U.S. Government securities.

MUNICIPAL SECURITIES
- --------------------

     Balanced Fund may invest up to 5% of its net assets 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.

     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 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 

                                      B-11
<PAGE>
 
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, the Advisers 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 ("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 

                                      B-12
<PAGE>
 
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 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 

                                      B-13
<PAGE>
 
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 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 

                                      B-14
<PAGE>
 
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.

     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 

                                      B-15
<PAGE>
 
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.  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 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 

                                      B-16
<PAGE>
 
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.  The  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
- --------------------------------

                                      B-17
<PAGE>
 
     Balanced Fund may invest up to 5% of its net assets 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 the
Fund's 15% limitation on investments in such securities.

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

                                      B-18
<PAGE>
 
     The Balanced Fund may invest in loan participations.  Such loans must be to
issuers in whose obligations the 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 the 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 the Balanced Fund acts as
co-lender in connection with a participation interest or when the Balanced Fund
acquires certain participation interests, the Balanced Fund will have direct
recourse against the borrower if the borrower fails to pay scheduled principal
and interest.  In cases where the Balanced Fund lacks direct recourse, it will
look to the agent bank to enforce appropriate credit remedies against the
borrower.  In these cases, the 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, the Balanced Fund may be regarded as a creditor
of the agent bank (rather than of the underlying corporate borrower), so that
the 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.  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 U.S. Equity and CORE Large Cap Growth
Funds may only enter into such transactions with respect to the S&P 500 Index,
for the CORE U.S. Equity Fund and a representative index in the case of the CORE
Large Cap Growth Fund. 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 

                                      B-19
<PAGE>
 
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 U.S. Equity, CORE
Large Cap Growth and CORE Small Cap Equity Funds) can sell futures contracts on
a specified currency to protect against a decline in the value of such currency
and its portfolio securities which are quoted or denominated in such currency.
Each Fund (other than 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.  The Balanced Fund may also
use futures contracts to 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 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 U.S. Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds)

                                      B-20
<PAGE>
 
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 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 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 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.

                                      B-21
<PAGE>
 
     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.  A Fund will determine that the price
fluctuations in the futures contracts and options on futures used for hedging
purposes are substantially related to price fluctuations in securities held by
the Fund or which it expects to purchase.  Except as stated below, each Fund's
futures transactions will be entered into for traditional hedging purposes --
i.e., futures contracts will be sold to protect against a decline in the price
of securities (or the currency in which they are quoted or denominated) that the
Fund owns, or futures contracts will be purchased to protect the Fund against an
increase in the price of securities (or the currency in which they are quoted or
denominated) it intends to purchase.

     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 (see
"Taxation").

     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
foreign currencies because the value of such securities is likely to fluctuate
as a result of independent factors not related to currency fluctuations.

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 (other than CORE U.S. Equity
and CORE Large Cap Growth Funds).  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 

                                      B-22
<PAGE>
 
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 would have deposited with
its custodian cash or liquid assets with a value at least equal to the exercise
price of the put option.  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.

     In addition, a written call option or put option may be covered by
maintaining segregated cash or liquid assets (either of which may be quoted or
denominated in any currency), by entering into an offsetting forward contract
and/or by purchasing an offsetting option 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 composed 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 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 (other than the CORE U.S. Equity and CORE
Large Cap Growth Funds) 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.

                                      B-23
<PAGE>
 
     A Fund would normally 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 would normally 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 Fund, with respect to up to 5% of its net
assets, 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 Fund may purchase or write yield curve options for the same
purposes as other options on securities.  For example,  Balanced 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 Fund may also purchase or write yield curve options in an effort to
increase its current income if, in the judgment of the Adviser, Balanced 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, if the spread moves in a direction or to
an extent which was not anticipated.

     Yield curve options written by the Balanced Fund will be "covered."  A call
(or put) option is covered if the Balanced 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 Balanced Fund's net liability under the
two options.  Therefore, the Balanced Fund's liability for such a covered option
is 

                                      B-24
<PAGE>
 
generally limited to the difference between the amount of the Balanced Fund's
liability under the option written by the Balanced Fund less the value of the
option held by the Balanced 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
purchase may be affected by options written or purchased by other investment
advisory clients of the 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 successful use of protective
puts for hedging purposes depends in part on the 

                                      B-25
<PAGE>
 
Adviser's ability to predict future price fluctuations and the degree of
correlation between the options and securities markets.

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 Investment Company Act of 1940, as amended (the "Act").
REITs (especially mortgage REITs) are also subject to interest rate risks.

WARRANTS AND STOCK PURCHASE RIGHTS
- ----------------------------------

     Each Fund may invest up to 5% of its net assets, calculated at the time of
purchase, 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 appropriate by the Adviser
for investment by the Fund.  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
- ------------------

     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 Adviser,
to offer better opportunity 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 

                                      B-26
<PAGE>
 
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.  The Balanced,
CORE International Equity, International Equity, European Equity, International
Small Cap, Emerging Markets Equity and Asia Growth Funds may be subject to
currency exposure independent of their 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.

     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 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.

                                      B-27
<PAGE>
 
     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 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.

     Each Fund (except 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.

     A Fund (other than CORE U.S. Equity, CORE Large Cap Growth and CORE Small
Cap Equity Funds) may invest in securities of issuers domiciled in a country
other than the country in whose currency the instrument is denominated or
quoted.  The Funds may also invest in securities quoted or denominated in the
European Currency Unit ("ECU"), which is a "basket" consisting of specified
amounts of the currencies of certain of the member states of the European
Community.  The specific amounts of currencies comprising the ECU may be
adjusted by the Council of Ministers of the European Community from time to time
to reflect changes in relative values of the underlying currencies.  In
addition, the Funds may invest in securities quoted or denominated in other
currency "baskets."

     INVESTING IN EMERGING MARKETS, INCLUDING ASIA AND EASTERN EUROPE.  CORE
International Equity, International Equity, European 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 Emerging Country
issuers and Asian Companies (as defined in the Prospectus) (in the case of Asia
Growth Fund), as well as the risks associated with investments quoted or
denominated in foreign currencies.  The Balanced, Growth and Income, Small Cap
Value, Mid Cap Equity and 

                                      B-28
<PAGE>
 
Capital Growth 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.

     Certain of the Emerging Country securities markets are 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.  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 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 (such as Malaysia) is subject to restrictions which require
governmental comments 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.

                                      B-29

     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.  Such
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; and (v) ethnic, religious and
racial disaffection or conflict.  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.

     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 is 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.

                                      B-30
<PAGE>
 
     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 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.  The Growth and Income, Mid
Cap Equity, Capital Growth and Small Cap Value Funds may enter into forward
foreign currency exchange contracts for hedging purposes.  The 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.

                                      B-31
<PAGE>
 
     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 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 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 purchase and
sell forward contracts to seek to increase total return when GSAM or GSAMI
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 Fund's portfolio.

     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 

                                      B-32
<PAGE>
 
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. 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. The segregated assets will be
marked-to-market on a daily basis. 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.

     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.  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 or force the Fund to cover its
commitments for purchase or resale, if any, at the current market price.

     WRITING AND PURCHASING CURRENCY CALL AND PUT OPTIONS. Each Fund (except
CORE U.S. Equity, CORE Large Cap Growth and CORE Small Cap Equity Funds) may
write covered put and call options and purchase put and call options on foreign
currencies for the purpose of protecting against declines in the U.S. dollar
value of portfolio securities and against increases in the U.S. dollar cost of
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.

     Balanced, CORE International Equity, International Equity, European Equity,
Japanese Equity, International Small Cap, Emerging Markets Equity and Asia
Growth Funds may use options on currency to cross-hedge, 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.  In addition, Balanced,
CORE International Equity, International Equity, European Equity, Japanese
Equity, International Small Cap, Emerging Markets Equity and Asia Growth Funds
may purchase call or put options on currency to seek to increase total return
when the Adviser anticipates that the currency will appreciate or depreciate in
value, but the securities quoted or denominated in that 

                                      B-33
<PAGE>
 
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 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 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 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 "Written
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 would also be able to
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,
Balanced, CORE International Equity, International Equity, European Equity,
Japanese Equity, International Small Cap, Emerging Markets Equity and Asia
Growth Funds may use options on currency to seek to increase total return.
Balanced, CORE International Equity, International Equity, European Equity,
Japanese Equity, International Small Cap, Emerging Markets Equity and Asia
Growth 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, Balanced, CORE International Equity, International Equity, European
Equity, Japanese Equity, International Small Cap, Emerging Markets Equity and
Asia 

                                      B-34
<PAGE>
 
Growth Funds may forego the opportunity to profit from an increase in the
market value of the  underlying currency.  Also, when writing put options,
Balanced, CORE International Equity, International Equity, European Equity,
Japanese Equity, International Small Cap, Emerging Markets Equity and Asia
Growth 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 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
- -------------------------------

     The Balanced, CORE International Equity, International Equity, European
Equity, Japanese Equity, International Small Cap, Emerging Markets Equity and
Asia Growth Funds may, with respect to up to 5% of their net assets, enter into
currency swaps for both hedging purposes and to seek to increase total return.
In addition, the Balanced and Real Estate Securities Funds may, with respect to
5% of their net assets, 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 

                                      B-35
<PAGE>
 
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.

     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 net amount payable under an interest rate,
index or mortgage swap and the entire amount of the payment stream payable by a
Fund under a currency swap or an interest rate floor, cap or collar is
segregated in cash or liquid assets, the Funds and the 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 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 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 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 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.

                                      B-36

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.  The counterparty to an equity swap contract will typically be a
bank, investment banking firm or broker/dealer.  The counterparty will generally
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, plus the dividends that would have been received on those
stocks.  The Fund will 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 any 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.

     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.  The net amount of the excess, if any, of a Fund's obligations over its
entitlements with respect to each equity swap will be accrued on a daily basis
and an amount of cash or liquid assets, having an aggregate net asset value at
least equal to such accrued excess will be maintained in a segregated account by
a Fund's custodian.  Inasmuch as these transactions are entered into for hedging
purposes or are offset by segregated cash or liquid assets, as permitted by
applicable law, the Funds and their 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.

     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 over-the-counter market.  The 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.

     The Funds will not enter into any swap transactions unless the unsecured
commercial paper, senior debt or claims-paying ability of the other party is
rated A or better by a nationally recognized statistical rating organization.
If there is a default by the other party to such a transaction, a Fund will have
contractual remedies pursuant to the agreements related to the transaction.

     The use of equity swaps is a highly specialized activity which involves
investment techniques and risks different from those associated with ordinary
portfolio securities transactions.  If the Advisers are incorrect in their
forecasts of market values, the investment performance of a Fund would be less
favorable than it would have been if this investment technique were not used.

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 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 Advisers to be of good standing,
and when, in the judgment of the Advisers, the consideration which can be earned
currently from securities loans of this type justifies the attendant risk.  If
the 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 up to 5% of its net assets, calculated at the time of
purchase, 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 

                                      B-38
<PAGE>
 
least one nationally recognized statistical rating organization. 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 5% of its net assets in the
securities of other 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 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 Adviser or
any of its affiliates acts as adviser, the advisory and administration fees
payable by the Fund to an 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 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).  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 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 (other than the Real Estate Securities
Fund) may, subject to the limitations stated above, invest in World Equity
Benchmark 

                                      B-39
<PAGE>
 
Shares ("WEBS") and similar securities that invest in securities included in
foreign securities indices.

REPURCHASE AGREEMENTS
- ---------------------

     Each Fund may enter into repurchase agreements with selected broker-
dealers, banks or other financial institutions.  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.  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.

     As with any unsecured debt instrument purchased for a Fund, the 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 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.

REVERSE REPURCHASE AGREEMENTS
- -----------------------------


  The Balanced Fund may borrow money for temporary purposes 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 

                                      B-40
<PAGE>
 
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 1940 Act


                            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.

     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 

                                      B-41
<PAGE>
 
                  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.

         Each Fund 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
objective, restrictions and policies as the Fund.

          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 Fund may not:

          (a)  Invest in companies for the purpose of exercising control or
               management.

          (b)  Invest more than 15% of the Fund's net assets in illiquid
               investments including repurchase agreements maturing in 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.

                                     B-42
<PAGE>
 
          (c)  Purchase additional securities if the Fund'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.

MANAGEMENT SERVICES
===================

          As stated in the Funds' Prospectus, GSFM, One New York Plaza, New
York, New York, a Delaware limited partnership and an affiliate of Goldman
Sachs, 85 Broad Street, New York, New York, serves as investment adviser to CORE
U.S. Equity and Capital Growth Funds.  GSAM, One New York Plaza, New York, New
York, a separate operating division of Goldman Sachs, serves as investment
adviser to Balanced, Growth and Income, CORE Large Cap Growth, CORE Small Cap
Equity, CORE International Equity, Real Estate Securities, Mid Cap Equity and
Small Cap Value Funds.  GSAMI, 133 Peterborough 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.
See "Management" in the Funds' Prospectus for a description of the applicable
Adviser's duties to the Funds.

          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 U.S. 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.

          The Advisers have access to 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 1,700 companies, including approximately 2,000
U.S. corporations in 60 industries.  The in-depth information and analyses
generated by Goldman Sachs' research analysts are available to the 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 Advisers have access to Goldman Sachs'
economics research.  The Economics Research Department 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 the
Institutional Investor's annual "All British Research Team Survey" in 

                                      B-51
<PAGE>
 
the following categories: Economics (U.K.) 1986-1993; Economics/International
1989-1993; and Currency Forecasting 1986-1993. In addition, the team has also
earned top rankings in the annual "Extel Financial Survey" of U.K. investment
managers in the following categories: U.K. Economy 1989-1995; International
Economies 1986, 1988-1995; and Currency Movements 1986-1993.

          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 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 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.

          Each Fund's management agreement provides that the Advisers may render
similar services to others as long as the services provided by the Advisers
thereunder are not impaired thereby.

          The 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 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 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 other 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 22, 1998. These arrangements were most recently approved by the
shareholders of each Fund (other than CORE Large Cap Growth, CORE Small Cap
Equity, CORE International Equity, Real Estate Securities, European Equity,
Japanese Equity, International Small Cap and Emerging Markets Equity Funds) on
April 21, 1997.  The sole shareholder of the 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 30, 1997, July 21, 1997, July 21, 1997,
January 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, 1999 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  Fund 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 

                                      B-52
<PAGE>
 
voting on such approval. Each management agreement will terminate automatically
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 Fund on 60 days' written notice to the Adviser and by
the Adviser on 60 days' written notice to the Trust.

          Pursuant to the management agreements the Advisers are entitled to
receive the fees listed below, payable monthly based on such Fund's average
daily net assets.  In addition, the Advisers are voluntarily limiting their
management fees for certain funds to the annual rates also listed below:

GSAM, GSFM and GSAMI may discontinue or modify the above limitations in the

  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.

/1/  The CORE Large Cap Growth, CORE Small Cap Equity, CORE International
     Equity, European Equity, Japanese Equity, International Small Cap, Emerging
     Markets Equity and Real Estate Securities Funds commenced operations on May
     1, 1997, August 15, 1997, August 15, 1997, October 1, 1998, May 1, 1998,
     May 1, 1998, December 15, 1997 and July 27, 1998, respectively.

     Under the Management Agreement, each 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 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
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) 

                                      B-54
<PAGE>
 
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 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 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.

     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 Advisers and/or their affiliates
will not initiate or recommend certain types of transactions in certain
securities or instruments with respect to which the Advisers and/or their
affiliates are performing services or when position limits have been reached.

     In connection with their management of the Funds, the Advisers may have
access to certain fundamental analysis and proprietary technical models
developed by Goldman Sachs and other affiliates.  The 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
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 Advisers in managing the Funds.

     The results of each Fund's investment activities may differ significantly
from the results achieved by the 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 

                                      B-55
<PAGE>
 
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
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.

     Each 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.

                                      B-56
<PAGE>
 
     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 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.  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 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 B Shares were outstanding during
the fiscal year ended January 31, 1996.  No Class C Shares were outstanding
during the fiscal years ended January 31, 1996 and 1997.

     Goldman Sachs retained the following 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

     Except as set forth in the Prospectus under "Management," the Trust is
responsible for the payment of its expenses.  The expenses include, without
limitation, the fees payable to the Advisers, 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, 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,

     The Advisers voluntarily have agreed to reduce or limit certain "Other
Expenses" (excluding management, distribution and service fees, transfer agency

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 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 Adviser's costs of
performing certain accounting services not being provided by a Fund's Custodian.

     For the last three fiscal years the amounts of certain "Other Expenses" of
each Fund then in existence that were reduced or otherwise limited were as

CUSTODIAN AND SUB-CUSTODIANS

<PAGE>
 
     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 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 Advisers are
generally required to give primary consideration to obtaining the most favorable
price and efficient execution under the circumstances.  This means that an
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 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 Advisers will consider research and investment services provided by
brokers or dealers who effect or are parties to portfolio transactions of a
Fund, the 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 

                                      B-62
<PAGE>
 
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 Advisers in the performance of their decision-making
responsibilities. Such services are used by the 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 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 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 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
Adviser acts as investment adviser or subadviser), the 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 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 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 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

                                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 (as defined in the Prospectus).

     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

                                      B-68
<PAGE>
 
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 mean between the closing bid and asked
prices, or if closing bid and asked prices are not available, at the exchange
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 securities
will be valued at the mean between the bid and asked prices 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 mean between the last bid and asked price; (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 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 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
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 rats 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.  Events affecting the values of portfolio securities that
occur between the time their prices are determined and the close of regular
trading on the New York Stock Exchange will not be reflected in a Fund's
calculation of net asset values unless the Trust's Valuation Committee deem that
the particular event would materially affect net asset value, in which case an
adjustment may be made.

     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, 

                                      B-69
<PAGE>
 
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 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

     A Fund 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.

     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 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.

     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 

                                      B-70
<PAGE>
 
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

Business Week, Consumer's Digest, Consumer's Report, Investors Business Daily,
The New York Times, Kiplinger's Personal Finance Magazine, Changing Times,
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

indices and the characteristics of such benchmark investments are not identical
to, and in some cases are very different from, those of the Fund's portfolio.
These 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 Fund to calculate its performance figures.

          The CORE Large Cap Growth Fund was organized on May 1, 1997 and has no
operating or performance history prior thereto. However, in accordance with
interpretive positions expressed by the staff of the SEC, the Fund has adopted
the adjusted performance record of a separate account managed by the Advisers
for periods prior to the Funds' commencement of operations which converted into
Class A Shares as of the commencement date. Any quotation of performance data of
this Fund relating to this period will include the adjusted performance record
of the applicable separate account. 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 as
stated in the expense table in the Prospectus. 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 will be
calculated pursuant to SEC approved methodology.  Prior to May 1, 1997, the
separate account was a separate investment advisory account under discretionary
management by the 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 the 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 16, 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 by the staff of the SEC, each of these Funds has adopted the
performance records of its respective Class A Shares from that class' inception
date (October 12, 1994, April 20, 1990, October 22, 1992, 

                                      B-73
<PAGE>
 
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 adjusted 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 Fund. These expenses include asset-
based charges (i.e., fees under Distribution and Service Plans) imposed and
other operating expenses. Total return quotations are calculated pursuant to 
SEC-approved methodology.

     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 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 may be 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 Growth, European Equity, Japanese Equity, International Small
Cap, Emerging Markets Equity and Real Estate Securities Funds were reorganized
from series of a Maryland corporation as part of Goldman Sachs Trust, a Delaware
business trust, by a Declaration of Trust dated January 28, 1997, on April 30,
1997.

     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.   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 the Funds into five classes:
Institutional Shares, Service Shares, Class A Shares, Class B Shares and Class C
Shares.

                                      B-79
<PAGE>
 
     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 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 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 fund.  See "Exchange Privilege" 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 (.50% with respect to the CORE
International Equity, International Equity, European Equity, Japanese Equity,
International Small Cap, Emerging Markets, Asia Growth, Global Income 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 

                                      B-80
<PAGE>
 
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.

     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 directors 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 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.

                                      B-82

     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 Trust Instrument 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 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-84
<PAGE>
 
GENERAL
=======

     Each Fund is a separate taxable entity.  Real Estate Securities, European
Equity, Japanese Equity and International Small Cap 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 

                                      B-85
<PAGE>
 
on long-term capital gains, (i) will be required to include in income for
federal income tax purposes, as long-term 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.  Asia Growth Fund had approximately $184,000, $5,487,000 and $10,408,000
and $14,137,000 at October 31, 1997 of capital loss carry forwards expiring in
2002, 2003, 2004 and 2005, respectively, for federal tax purposes. 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 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 

                                      B-86
<PAGE>
 
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 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 (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 

                                      B-87
<PAGE>
 
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 Funds 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 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) 

                                      B-88
<PAGE>
 
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 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 

                                      B-89
<PAGE>
 
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.

     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 

                                      B-90
<PAGE>
 
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.

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.

     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 

                                      B-91
<PAGE>
 
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 Independent Public
Accountants, contained in the 1998 Annual Report of each of the Funds (except
Real Estate Securities, European Equity, Japanese Equity and International Small
Cap Funds), are incorporated herein by reference into this Additional Statement.
In addition, the unaudited financial statements contained in the Semi-Annual
Report for the period ended July 31, 1998 of each of the Funds (except Real
Estate Securities and European Equity Funds) are incorporated by reference into
this Additional Statement.  No other part of the Annual or any Semi-Annual
Report is incorporated by reference herein.

                               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 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
a Distribution or Service Plan described in the Prospectuses and this Additional
Statement.  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 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 

                                      B-92
<PAGE>
 
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 dealers as set forth in the
Prospectus. These Additional Payments may take the form of "due diligence"
payments for an Authorized Dealer'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 a dealer'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 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 Adviser, Distributor and their affiliates may be
a fixed dollar amount, may be based on the number of customer accounts
maintained by an Authorized Dealer, or may be based on a percentage of the value
of Shares sold to, or held by, customers of the Authorized Dealers involved, and
may be different for different Authorized Dealers. 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 in which participants may
receive prizes such as travel awards, merchandise and cash and/or investment
research pertaining to particular securities and other financial instruments or
to the securities and financial markets generally, educational information and
related support materials and software. The Adviser, Distributor and their
affiliates may also pay for the travel expenses, meals, lodging and
entertainment of Authorized Dealers and their salespersons and guests in
connection with educational, sales and promotional programs subject to
applicable NASD regulations.

     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.

                         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 "Distribution and Service Plans" in the Prospectus.

                                      B-93
<PAGE>
 
     The Plans for each Fund were most recently approved on July 22, 1998 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 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.

     The Plans will remain in effect until May 1, 1999 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 

                                      B-94
<PAGE>
 
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.

          For the fiscal years ended January 31, 1998, January 31, 1997 and
January 31, 1996 the distribution fees paid to Goldman Sachs pursuant to its
Class A Plan by each Fund then in existence were as follows:

The following information supplements the information in the Prospectus under
the captions "How to Invest," "How to Sell Shares of the Funds" and "Dividends."
Please see the Prospectus for more complete information.

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 

                                     B-101
<PAGE>
 
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.

CROSS-REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS
- -------------------------------------------------

A Fund shareholder should obtain and read the prospectus relating to any other
Fund, 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 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
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.

                                     B-103
<PAGE>
 
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 "How to Invest -- Waiver or Reduction of Continent Deferred Sales
Charge" 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 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 

                                     B-105
<PAGE>
 
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 legal advisers before
investing fiduciary assets in  Service Shares of a Fund.  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 the Plan and related Service Agreements at a meeting called for the
purpose of voting on such Plan and Service Agreements on April 22, 1998.  The
Plan and related Service Agreements will remain in effect until May 1, 1999 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.  In the Trustees' quarterly review of the Plan and related Service
Agreements, the Board will consider their continued appropriateness and the
level of compensation provided therein.

                                   APPENDIX A

                          DESCRIPTION OF BOND RATINGS*

                        MOODY'S INVESTORS SERVICE, INC.

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

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

          A:  Bonds which are rated A possess many favorable investment
attributes and are to be considered as upper medium-grade obligations.  Factors
giving security to principal and interest are considered adequate, but elements
may be present which suggest a susceptibility to impairment sometime in the
future.

          Baa:  Bonds which are rated Baa are considered as medium-grade
obligations, i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time.  Such bonds lack outstanding
investment characteristics and in fact have speculative characteristics as well.

          Ba:  Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate, and thereby not well
safeguarded during both good and bad times over the future.  Uncertainty of
position characterizes bonds in this class.

*         THE RATING SYSTEMS DESCRIBED HEREIN ARE BELIEVED TO BE THE MOST RECENT
          RATING SYSTEMS AVAILABLE FROM MOODY'S INVESTORS SERVICE, INC. AND
          STANDARD AND POOR'S RATINGS GROUP AT THE DATE OF THIS ADDITIONAL
          STATEMENT FOR THE SECURITIES LISTED. RATINGS ARE GENERALLY GIVEN TO
          SECURITIES AT THE TIMES OF ISSUANCE. WHILE THE RATING AGENCIES MAY
          FROM TIME TO TIME REVISE SUCH RATINGS, THEY UNDERTAKE NO OBLIGATION TO
          DO SO, AND THE RATINGS INDICATED DO NOT NECESSARILY REPRESENT RATINGS
          WHICH WILL BE GIVEN TO THESE SECURITIES ON THE DATE OF THE FUND'S
          FISCAL YEAR END.

                                     1 - A
<PAGE>
 
          B:  Bonds which are rated B generally lack characteristics of
desirable investment.  Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small.

          Caa:  Bonds which are rated Caa are of poor standing.  Such issues may
be in default or there may be present elements of danger with respect to
principal or interest.

          Ca:  Bonds which are rated Ca represent obligations which are
speculative in a high degree.  Such issues are often in default or have other
marked shortcomings.

          C:  Bonds which are rated C are the lowest rated class of bonds which
may be in default, and issues so rated can be regarded as having extremely poor
prospects of ever attaining any real investment standing.

          UNRATED:  Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.

          Should no rating be assigned, the reason may be one of the following:

          1.    An application for rating was not received or accepted.

          2.    The issue or issuer belongs to a group of securities or
                companies that are not rated as a matter of policy.

          3.    There is a lack of essential data pertaining to the issue or
                issuer.

          4.    The issue was privately placed, in which case the rating is not
                published in Moody's publications.

          Suspension or withdrawal may occur if new and material circumstances
arise, the effects of which preclude satisfactory analysis; if there is no
longer available reasonable up-to-date data to permit a judgment to be formed;
if a bond is called for redemption; or for other reasons.

          NOTE:  Those bonds in the Aa, A, Baa, Ba and B groups which Moody's
believes possess the strongest investment attributes are designated by the
symbols Aa1, A1, Baa1, Ba1 and B1.

          Moody's also provides credit ratings for commercial paper.  These are
promissory obligations (1) not having an original maturity in excess of one
year, unless explicitly noted.

                 Description of Ratings of State and Municipal
                             Commercial Paper
              ---------------------------------------------------

          Moody's commercial paper ratings are opinions of the ability of
issuers to repay punctually senior debt obligations which have an original
maturity in excess of nine months.  Moody's three highest commercial paper
rating categories are as follows:

                                     2 - A
<PAGE>
 
     PRIME 1:  Issuers rated Prime-1 (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 structures with moderate reliance on
             debt and ample asset protection.

          -  Broad margins in earnings coverage of fixed financial charges and
             high internal cash generation.

          -  Well established access to a range of financial markets and assured
             sources of alternate liquidity.

     PRIME-2:  Issuers rated Prime-2 (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.  Capitalized characteristics, while still
     appropriate, may be more affected by external conditions.  Ample alternate
     liquidity is maintained.

     PRIME-3:  Issuers rated Prime-3 (or supporting institutions) have an
     acceptable ability for repayment of senior short-term 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.


                        STANDARD & POOR'S RATINGS GROUP

          AAA:  Bonds and debt rated AAA have the highest rating assigned by
Standard & Poor's.  Capacity to meet the financial commitment on the obligation
is extremely strong.

          AA:  Bonds and debt rated AA have a very strong capacity to meet the
financial commitment on the obligation and differ from the higher rated issues
only in small degree.

          A:   Bonds and debt rated  A have a strong capacity to meet the
financial commitment on the obligation although they are somewhat more
susceptible to the adverse effects of changes in circumstances and economic
conditions than bonds in  higher rated categories.

                                     3 - A
<PAGE>
 
          BBB:  Bonds and debt rated BBB are regarded as having an adequate
capacity to meet the financial commitment on the obligation.  Whereas they
normally exhibit adequate protection parameters, adverse economic conditions or
changing circumstances are more likely to lead to a weakened capacity of the
obligor.

          BB, B, CCC, CC, C:  Bonds and debt rated BB, B, CCC, CC and C are
regarded as having significant speculative characteristics with respect to the
capacity to meet the financial commitment on the obligation.  BB indicates the
least degree of speculation and C the highest.  While such bonds will likely
have some quality and protective characteristics, these are outweighed by large
uncertainties of major risk exposures to adverse conditions.

          BB:   Bonds and debt rated BB have less vulnerability to nonpayment
than other speculative issues.  However, such securities face major ongoing
uncertainties or exposure to adverse business, financial, or economic conditions
which could lead to the obligor's inadequate capacity to meet the financial
commitment on the obligation.

          B:    Bonds and debt rated B are more vulnerable to non-payment but
the obligor currently has the capacity to meet its financial commitment on the
obligation. Adverse business, financial or economic conditions will likely
impair capacity or willingness to meet its financial commitment on the
obligation.

          CCC:  Bonds and debt rated CCC are currently vulnerable to non-
payment, and are dependent upon favorable business, financial, and economic
conditions to meet their financial commitment on the obligation.  In the event
of adverse business, financial, or economic conditions, such securities are not
likely to have the capacity to meet their financial commitment on the
obligation.

          CC:   The rating CC is typically applied to bonds and debt that are
currently highly vulnerable to non-payment.

          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 debt service
payments on this obligation are continued.

          D:    Bonds and debt rated D 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 Standard & Poor's
believes that such payments will be made during such grace period.  The D rating
also will be used upon the filing of a bankruptcy petition if debt service
payments are jeopardized.

          PLUS (+) OR MINUS (-):  The ratings from "AA" to "CCC" may be modified
by the addition of a plus or minus sign to show relative standing within the
major rating categories.

          R:    This rating is attached to highlight derivative, hybrid, and
certain other obligations that Standard & Poor's believes may experience high
volatility or high variability in expected returns due to non-credit risks.
Examples of such obligations are: securities whose principal or 

                                     4 - A
<PAGE>
 
interest return is indexed to equities, commodities, or currencies, certain
swaps and options; and interest-only and principal-only mortgage securities. The
absence of an "r" symbol should not be taken as an indication that an obligation
will exhibit no volatility or variability in total return.

                        STANDARD & POOR'S RATINGS GROUP

          A Standard & Poor's 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. Standard & Poor's commercial paper rating categories are as
follows:

          A-1  Obligations are rated in the highest category indicating that the
obligor's capacity to meet its financial commitment 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 rated "A-
1".  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 on favorable business, financial, and economic conditions for the
obligor to meet its financial 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 Standard & Poor's believes such
payments will be made during such grace period.  The "D" rating will also be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments on an obligation are jeopardized.

Bond Ratings
- ------------

          The ratings represent Fitch's assessment of the issuer's ability to
meet the obligations of a specific debt issue or class of debt.  The ratings
take into consideration special features of the issue, its relationship to other
obligations of the issuer, the current financial condition and operative

                                     5 - A
<PAGE>
 
performance of the issuer and of any guarantor, as well as the political and
economic environment that might affect the issuer's future financial strength
and credit quality.

          AAA:  Bonds rated AAA are considered to be investment grade and of the
highest credit quality.  The obligor has an exceptionally strong capacity for
timely payment of financial commitments, which is unlikely to be adversely
affected by reasonably foreseeable events.

          AA:   Bonds rated AA are considered to be investment grade and of very
high credit quality.  These ratings denote a very low expectation of investment
risk and indicate very strong capacity for timely payment of financial
commitments.  This capacity is not significantly vulnerable to foreseeable
events.

          A:    Bonds rated A are considered to be investment grade and of high
credit quality.  These ratings denote a low expectation of investment risk and
indicate strong capacity of timely payment of financial commitments.

          BBB:  Bonds rated BBB are considered to be investment grade and of
good credit quality.  These ratings denote that there is currently a low
expectation of investment risk.  The capacity for timely payment of financial
commitments is adequate, but adverse circumstances  and in economic conditions
are more likely to impair this category.

          BB:   Bonds are 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:  Bonds have certain identifiable characteristics that, if not
remedied, may lead to default.  The ability to meet obligations requires an
advantageous business and economic environment.

          CC:   Bonds are minimally protected. Default in payment of interest
and/or principal seems probable over time.

          C:    Bonds are in imminent default in payment of interest or
principal.

          DDD, DD, AND D:    Bonds are in default on interest and/or principal
payments.  Such bonds are extremely speculative and should be valued on the
basis of their ultimate recovery value in liquidation or reorganization of the
obligor.  DDD represents the highest potential for recovery on these bonds, and
D represents the lowest potential for recovery.

                                     6 - A
<PAGE>
 
          PLUS (+) AND MINUS (-) signs are used with a rating symbol to indicate
the relative position of a credit within the rating category.  The Fitch IBCA
ratings from and including "AA" to "B" may be modified by the addition of a plus
or minus sign.

Investment Grade Short-Term Ratings
- -----------------------------------

          Fitch IBCA's 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.

F 1:      Highest Credit Quality. Issues assigned this rating reflect the
          strongest capacity for timely payment of financial commitments; may
          have an added "+" to denote any exceptionally strong credit feature.

F 2:      Good Credit Quality.  Issues assigned this rating have a satisfactory
          capacity for timely payment of financial commitments, but the margin
          of safety is not as great as for issues assigned F 1 ratings.

F 3:      Fair Credit Quality.  Issues assigned this rating have characteristics
          suggesting that the degree of 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
          the capacity for meeting financial commitments is solely reliant upon
          a sustained, favorable business and economic environment.

D:        Default. Issues assigned this rating are in actual or imminent payment
          default.

LOC:      The symbol LOC indicates that the rating is based on a letter of
          credit issued by a commercial bank.

Long Term Debt and Preferred Stock
- ----------------------------------

          AAA:   Highest credit quality.  The risk factors are negligible, being
only slightly more than for risk-free U.S. Treasury debt.

          AA+, AA, AA-:  High credit quality.  Protection  factors are strong.
Risk is modest but may vary slightly from time to time because of economic
conditions.  However, risk factors are more variable and greater in periods of
economic stress.

                                     7 - A

          A+, A, A-:   Debt possesses protection factors which are average but
adequate. However, risk factors are more variable and greater in periods of
economic stress.

          BBB+, BBB, BBB-:  Below average protection factors but still
considered sufficient for prudent investment.  Considerable variability in risk
during economic cycles.

          BB+, BB, BB-: Below investment grade but deemed likely to meet
obligations when due.  Present or prospective financial protection factors
fluctuate according to industry conditions or company fortunes.  Overall quality
may move up or down frequently within this category.

          B+, B, B-:  Below investment  grade and possessing risk that
obligations will not be met when due.  Financial protection factors will
fluctuate widely according to economic cycles, industry conditions and/or
company fortunes.  Potential exists for frequent changes in the rating within
this category or into a higher or lower rating grade.

          CCC:   Well below investment grade securities.  Considerable
uncertainty exists as to timely payment of principal, interest or preferred
dividends.  Protection factors are narrow and risk can be substantial with
unfavorable economic/industry conditions, and/or with unfavorable company
developments.

          D:  Defaulted debt obligation.

Commercial Paper/Certificates of Deposits
- -----------------------------------------

D-1+:     Highest certainty of timely payment.  Short-term liquidity, including
          internal operating factors and/or ready access to alternative sources
          of funds, is clearly outstanding, and safety is just below risk-free
          U.S. Treasury short-term obligations.

D-1:      Very high certainty of timely payment. Liquidity factors are excellent
          and supported by good fundamental protection factors. Risk factors are
          minor.

D-1-:     High certainty of timely payment.  Liquidity factors are strong and
          supported by good fundamental protection factors.  Risk factors are
          very small.

D-2:      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:      Satisfactory liquidity and other protection factors qualify issues as
          investment grade. Risk factors are larger and subject to more
          variation.  Nevertheless, timely payment is expected.

                                     8 - A
<PAGE>
 
D-4:      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 failed to meet scheduled principal and/or interest payments.

NOTES:    Bonds which are unrated may expose the investor to risks with respect
          to capacity to pay interest or repay principal which are similar to
          the risks of lower-rated bonds. The Fund is dependent on the
          Investment Adviser's judgment, analysis and experience in the
          evaluation of such bonds.

          Investors should note that the assignment of a rating to a bond by a
          rating service may not reflect the effect of recent developments on
          the issuer's ability to make interest and principal payments.

Description of Ratings of State and Municipal Notes
- ---------------------------------------------------

MOODY'S INVESTORS SERVICE, INC.

          Moody's ratings for state and municipal short-term obligations  will
be 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.  Symbols used will be as follows:

          MIG-1/VMIG-1:  This designation denotes best quality enjoying 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.  Margins of
protection are ample although not so large as in the preceding group.

          MIG-3/VMIG-3:  This designation denotes favorable quality.  All
security elements are accounted for but there is 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 carrying
specific risk but having protection commonly regarded as required of an
investment security and not distinctly or predominantly speculative.

          SG:  This designation denotes speculative quality.  Debt instruments
in this category lack margins of protection.

                                     9 - A

STANDARD & POOR'S RATINGS GROUP

          A Standard and Poor's note rating reflects the liquidity concerns and
market access risks unique to notes.  Notes due in three years or less will
likely receive a note rating.

       Note rating symbols are as follows:

SP-1:     Strong capacity to pay principal and interest. Those issues determined
          to possess very strong characteristics will be given a plus (+)
          designation.

SP-2:     Satisfactory capacity to pay principal and interest with some
          vulnerability to adverse financial and economic changes over the term
          of the notes.

SP-3:     Speculative capacity to pay principal and interest.

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
assets diminish, reputation 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 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.

          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 distinction.

          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.
