 General Investment Management Approach
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the
 Funds. Goldman Sachs Asset Management is referred to in this Prospectus as
 the "Investment Adviser."
 
 
 Goldman Sachs' Money Market Investment Philosophy
 The Money Market Funds are managed to seek maximum current income consistent
 with the preservation of capital and daily liquidity. In managing the Funds,
 the Investment Adviser follows a conservative, risk-managed investment proc-
 ess that seeks to:
..Manage credit risk
..Manage interest rate risk
..Manage liquidity
 
 The Investment Adviser actively manages the Goldman Sachs Money Market Funds
 in designing and structuring the Fund's investment portfolios.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 The Investment Adviser follows a consistent five-step investment process
 across all of its money market portfolios.
 
 1. Define investment objectives and risk parameters
 The Investment Adviser works closely within Fund and Rule 2a-7 guidelines in
 seeking to meet investment objectives for each Fund.
 
 2. Establish benchmarks
 Benchmarks are the IBC Financial Data Universal Averages. Depending upon the
 eligible investments of each Fund, there is a corresponding IBC Index.
 
 3. Establish a risk-managed framework
 Understanding and managing risk is critical to the performance of money mar-
 ket fund portfolios.
 
 4. Actively manage the portfolios
 General portfolio strategy meetings are held weekly.
 
 5. Monitor Risk Exposure
 Risk reports enable the Investment Adviser to monitor portfolios on a daily
 basis and track all trading activity.
 
                                                                            1-KK

..The Funds: Each Fund's securities are valued by the amortized cost method as
  permitted under Rule 2a-7 of the Investment Company Act of 1940, as amended
  (the "1940 Act"). Under Rule 2a-7, each Fund may invest only in U.S. dollar
  denominated securities that are determined to present minimal credit risk
  and meet certain other criteria including those conditions relating to matu-
  rity, diversification and credit quality. These operating policies may be
  more restrictive than the fundamental policies set forth in the Statement of
  Additional Information (the "Additional Statement").
 
   .Taxable Funds: Prime Obligations, Money Market, Treasury Obligations and
    Government Portfolios.
    .Tax-Advantaged Funds: Treasury Instruments and Federal Portfolios.
   .Tax-Exempt Funds: Tax-Exempt Diversified, Tax-Exempt California and Tax-
    Exempt New York Portfolios.
..The Investors: The Funds are designed for investors seeking a high rate of
  return, a stable net asset value ("NAV") and convenient liquidation privi-
  leges. The Funds are particularly suitable for banks, corporations and other
  financial institutions that seek investment of short-term funds for their
  own accounts or for the accounts of their customers.
..NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
..Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
..Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
..Investment Restrictions: Each Fund is subject to certain investment restric-
  tions that are described in detail under "Investment Restrictions" in the
  Additional Statement. Fundamental investment restrictions and the investment
  objective of a Fund (except the Tax-Exempt California and Tax-Exempt New
  York Portfolios' objectives of providing shareholders with income exempt
  from California State and New York State and New York City personal income
  tax, respectively) cannot be changed without approval of a majority of the
  outstanding shares of that Fund. The Treasury Obligations Portfolio's policy
  of limiting its investments to U.S. Treasury Obligations and related repur-
  chase agreements is also fundamental. All investment policies not specifi-
  cally designated as fundamental are non-fundamental and may be changed with-
  out shareholder approval.
..Diversification. Diversification can help a Fund reduce the risks of invest-
  ing. In accordance with current regulations of the Securities and Exchange
  Commission

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
  (the "SEC"), each Fund may not invest more than 5% of the value of its total
  assets at the time of purchase in the securities of any single issuer with
  these exceptions: (a) the Tax-Exempt California and Tax-Exempt New York
  Portfolios may each invest up to 25% of their total assets in five or fewer
  issuers; and (b) each of the other Funds may invest up to 25% of its total
  assets in the securities of a single issuer for up to three business days.
  These limitations do not apply to cash, certain repurchase agreements, U.S.
  Government securities or securities of other investment companies. In addi-
  tion, securities subject to certain unconditional guarantees and securities
  that are not "First Tier Securities" as defined by the SEC are subject to
  different diversification requirements as described in the Additional State-
  ment.
 
                                                                            3-KK

 Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Treasury Obligations, Treasury Instru-
 ments, Government and Federal Portfolios seek to maximize current income to
 the extent consistent with the preservation of capital and the maintenance
 of liquidity by investing exclusively in high quality money market instru-
 ments.
 
 The Treasury Instruments and Federal Portfolios pursue their investment
 objectives by limiting their investments to certain U.S. Treasury obliga-
 tions and U.S. Government securities (each as defined in Appendix A),
 respectively, the interest from which is generally exempt from state income
 taxation. You should consult your tax adviser to determine whether distribu-
 tions from the Treasury Instruments and Federal Portfolios (and any other
 Fund that may hold such obligations) derived from interest on such obliga-
 tions are exempt from state income taxation in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
 Portfolios seek to provide shareholders, to the extent consistent with the
 preservation of capital and prescribed portfolio standards, with a high
 level of income exempt from federal income tax by investing primarily in
 municipal instruments.
 
 In addition, the Tax-Exempt California and Tax-Exempt New York Portfolios
 seek to provide shareholders with income exempt from California State and
 New York State and City personal income taxes, respectively.
 
 The Tax-Exempt Funds pursue their investment objectives by limiting their
 investments to securities issued by or on behalf of states, territories, and
 possessions of the United States and their political subdivisions, agencies,
 authorities and instrumentalities, and the District of Columbia, the inter-
 est from which, if any, is in the opinion of bond counsel excluded from
 gross income for federal income tax purposes, and not an item of tax prefer-
 ence under the federal alternative minimum tax.

 /6/Ordinarily expect that 100% of a Fund's portfolio securities will be
   invested in municipal obligations, but the Funds may, for temporary
   defensive purposes, hold cash or invest in short-term taxable securities.
 /7/To the extent permitted by Rule 2a-7, securities without short-term

   First Tier Securities, or to the extent that a Fund may purchase Second
   Tier Securities, comparable in quality to Second Tier Securities. In
   addition, a Fund holding a security supported by a guarantee or demand
   feature may rely on the credit quality of the guarantee or demand feature
   in determining the credit quality of the investment.
 /8/If such policy should change, private activity bonds subject to AMT would
   not exceed 20% of a Fund's net assets under normal market conditions.

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

Risks that apply to all Funds:
 
..Money Market Risk--The risk that a Fund will not be able to maintain a NAV
  per share of $1.00 at all times.
..Interest Rate Risk--The risk that during periods of rising interest rates,
  a Fund's yield (and the market value of its securities) will tend to be
  lower than prevailing market rates; in periods of falling interest rates, a
  Fund's yield will tend to be higher.
..Credit/Default Risk--The risk that an issuer or guarantor of a security, or
  a bank or other financial institution that has entered into a repurchase
  agreement, may default on its payment obligations.
..Management Risk--The risk that a strategy used by the Investment Adviser
  may fail to produce the intended results.
..Liquidity Risk--The risk that a Fund will be unable to pay redemption pro-
  ceeds within the time period stated in this Prospectus, because of either
  unusual market conditions, an unusually high volume of redemption requests,
  or other reasons.
..Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by
  the "Year 2000 Problem."
 
Risk that applies to the Government and Federal Portfolios:
 
..Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market, Tax-Exempt Diversified, Tax-Exempt
California and Tax-Exempt New York Portfolios:
 
..Concentration Risk--The risk that if a Fund invests more than 25% of its
  total assets in issuers within the same state, industry or economic sector,
  an adverse economic, business or political development may affect the value
  of the Fund's investments more than if its investments were not so concen-
  trated.
..Foreign Risk--The risk that a foreign security (or, in the case of the Tax-
  Exempt California and Tax-Exempt New York Portfolio, a foreign letter of
  credit or guarantee) could lose value as a result of political, financial
  and economic events in foreign countries, less stringent foreign securities
  regulations and accounting and disclosure standards, or other factors. The
  Money Market Portfolio may not invest more than 25% of its total assets in
  the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
Risk that applies to the Money Market Portfolio:
 
..Banking Industry Risk--The risk that if a Fund invests more than 25% of its
  total assets in bank obligations, an adverse development in the banking
  industry may affect the value of the Fund's investments more than if a
  Fund's investments were not invested to such a degree in the banking indus-
  try. Normally, the Money Market Portfolio intends to invest more than 25%
  of its total assets in bank obligations, and the Tax-Exempt California and
  Tax-Exempt New York Portfolio intend to invest at least 65% of their total
  assets in California municipal obligations and New York municipal obliga-
  tions, respectively. Banks may be particularly susceptible to certain eco-
  nomic factors such as interest rate changes, adverse developments in the
  real estate market, fiscal and monetary policy and general economic cycles.
 
Risk that applies to the Tax-Exempt Funds:
 
..Tax Risk--The risk that future legislative or administrative changes or
  court decisions may materially affect the ability of a Fund to pay federal
  tax-exempt dividends (in the case of each of these Funds) and state tax-
  exempt dividends (in the case of the Tax-Exempt California and Tax-Exempt
  New York Funds).
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

 ing in a Fund by showing: (a) changes in the performance of a Fund's ILA
 Shares from year to year; and (b) how the average annual returns of a Fund's
 ILA Shares compare to the returns of a composite of mutual funds with simi-
 lar investment objectives. The bar chart and table assume reinvestment of
 dividends and distributions. A Fund's past performance is not necessarily an
 indication of how the Fund will perform in the future. Performance reflects
 expense limitations in effect. If expense limitations were not in place, a
 Fund's performance would have been reduced. You may obtain a Fund's current
 yield by calling 1-800-621-2550.

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

Institutions that invest in ILA Shares on behalf of their customers may charge
other fees directly to their customer accounts in connection with their invest-
ments. You should contact your institution for information regarding such
charges. Such fees may affect the return their customers realize with respect
to their investments.
 
Certain institutions that invest in ILA Shares on behalf of their customers may
receive other compensation in connection with the sale and distribution of ILA
Shares or for services to their customers' accounts and/or the Funds. For addi-

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

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled.
 
 The Investment Adviser has voluntarily agreed to reduce or otherwise limit
 the daily expenses of each Fund (excluding fees payable under service,
 administration and distribution plans for certain share classes, taxes,
 interest, brokerage and litigation, indemnification and other extraordinary
 expenses) on an annualized basis to 0.43% of the average daily net assets of
 the Fund. Such reductions or limits, if any, are calculated monthly on a
 cumulative basis. These reductions or limits may be discontinued or modified
 only with the express approval of the Trustees.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606, also serves as the Fund's
 transfer agent (the "Transfer Agent") and as such, performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," which may lead to computer shutdowns or
 errors (commonly known as the "Year 2000 Problem"). To the extent these sys-
 tems conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.

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

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

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

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

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

 You should contact your institution or intermediary directly to learn

 These institutions may receive payments from the Funds or Goldman Sachs for
 the services provided by them with respect to the Funds' ILA Shares. These
 payments may be in addition to other payments borne by the Funds.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-

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

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
..Modify or waive the minimum investment and minimum account balance require-
  ment.
..Reject any purchase order for any reason.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange ILA Shares is
 determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
..NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (usu-
  ally 4:00 p.m. New York time). Fund Shares will be priced on any day the
  New York Stock Exchange is open, except for days on which Chicago, Boston
  or New York banks are closed for local holidays.
 
                                                                            3-MM
<PAGE>
 
..On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
..The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Generally, each Fund will redeem its ILA Shares
 upon request on any business day at their NAV next determined after receipt
 of such request in proper form. You may request that redemption proceeds be
 sent to you by check or by wire (if the wire instructions are on record).
 Redemptions may be requested in writing or by telephone.

 Certain institutions and intermediaries are authorized to accept redemption
 requests on behalf of the Funds as described under "How Do I Purchase Shares
 Through A Financial Institution?" You may also take advantage of the check
 redemption privilege, described below.
 
 When Do I Need A Signature Guarantee To Redeem Shares?
 Your redemption request must include a signature guarantee if any of the
 following situations apply:
..You would like the redemption proceeds sent to an address that is not your
  address of record; or
..You would like to change the bank designated on your Account Application.
 
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federal savings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption requests by
 telephone, Goldman Sachs employs reasonable procedures specified by the
 Trust to confirm that such instructions are genuine. If reasonable proce-
 dures are not employed, the Trust may be liable for any loss due to unautho-
 rized or fraudulent transactions. The following general policies are cur-
 rently in effect:
..All telephone requests are recorded.
..Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request will be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
..The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
                                                                            5-MM

..Although redemption proceeds will normally be wired as described above,
  each Fund reserves the right to pay redemption proceeds up to three busi-
  ness days following receipt of a properly executed wire transfer redemption
  request. If you are selling shares you recently paid for by check, the Fund
  will pay you when your check has cleared, which may take up to 15 days. If
  the Federal Reserve Bank is closed on the day that the redemption proceeds
  would ordinarily be wired, wiring the redemption proceeds may be delayed
  one additional business day.
..To change the bank designated on your Account Application you must send
  written instructions signed by an authorized person designated on the
  Account Application to the Transfer Agent.
..Neither the Trust, Goldman Sachs nor any other institution assumes any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
..If the redeemed shares were recently paid for by check, the Fund will pay
  the redemption proceeds when the check has cleared, which may take up to 15
  days.
 
 What Should I Know About The Check Redemption Privilege?
 You may elect to have a special account with State Street for the purpose of
 redeeming ILA Shares from your account by check.
 
6-MM

                                                               SHAREHOLDER GUIDE
 
 The following general policies govern the check redemption privilege:
..You will be provided with a supply of checks when State Street receives a
  completed signature card and authorization form. Checks drawn on the
  account may be payable to the order of any person in any amount over $500,
  but cannot be certified.
  .The payee of the check may cash or deposit it just like any other check
   drawn on a bank.
  .When the check is presented to State Street for payment, a sufficient
   number of full or fractional ILA Shares will be redeemed to cover the
   amount of the check.
  .Canceled checks will be returned to you by State Street.
..The check redemption privilege allows you to receive the dividends declared
  on the Shares that are to be redeemed until the check is actually proc-
  essed. Because of this feature, accounts may not be completely liquidated
  by check.
..If the amount of the check is greater than the value of the ILA Shares held
  in your account, the check will be returned unpaid. In this case, you may
  be subject to extra charges.
..Goldman Sachs Funds reserves the right to limit the availability of, modify
  or terminate the check redemption privilege at any time with respect to any
  or all shareholders.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
..Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 
 The Trust reserves the right to:
..Redeem your shares if your account balance falls below the minimum as a
  result of earlier redemptions. The Funds will give you 60 days' prior writ-
  ten notice to allow you to purchase sufficient additional Shares of the
  Fund in order to avoid such redemption.
..Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
..Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
                                                                            7-MM

 Can I Exchange My Investment From One Fund To Another?

 materially modified or withdrawn at any time upon 60 days' written notice to
 you.

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

 For federal income tax purposes, an exchange is treated as a redemption of
 the shares surrendered in the exchange, on which you may be subject to tax,
 followed by a purchase of shares received in the exchange. You should con-
 sult your tax adviser concerning the tax consequences of an exchange.
 
 What Types Of Reports Will I Be Sent Regarding Investments In Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-621-2550. You will also be provided with an
 individual monthly statement. Upon request, you will be provided with a
 printed confirmation for each transaction in your account. Any dividends and
 distributions paid by the Funds are also reflected in regular statements
 issued by Goldman Sachs to recordholders.
 
                                                                            9-MM
<PAGE>
 
Dividends
 
 
 All or substantially all of each Fund's net investment income will be
 declared as a dividend daily. Dividends will normally, but not always, be
 declared as of 4:00 p.m. New York time as a dividend and distributed to
 shareholders monthly. You may choose to have dividends paid in:
 
..Cash
..Additional shares of the same class of the same Fund
 
 You may indicate your election on your Account Application. Any changes may
 be submitted in writing to Goldman Sachs at any time. If you do not indicate
 any choice, your dividends and distributions will be reinvested automati-
 cally in the applicable Fund.
 
 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and December may be distributed during the
 subsequent calendar year. Although realized gains and losses on the assets
 of a Fund are reflected in the NAV of the Fund, they are not expected to be
 of an amount which would affect the Fund's NAV of $1.00 per share.
 
 The income declared as a dividend for the Treasury Obligations and Govern-
 ment Portfolios is based on estimates of net investment income for each
 Fund. Actual income may differ from estimates, and differences, if any, will
 be included in the calculation of subsequent dividends.
 
                                                                              17

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

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

 larly susceptible to certain economic factors, such as interest rate changes
 and adverse developments in the real estate markets. Fiscal and monetary
 policy and general economic cycles can affect the availability and cost of
 funds, loan demand and asset quality and thereby impact the earnings and
 financial conditions of banks.
 
 Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
 asset-backed and receivables-backed securities, whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed and receivables-backed securities are often subject to more
 rapid repayment than their stated maturity date would indicate as a result
 of the pass-through of prepayments of principal on the underlying loans.
 During periods of declining interest rates, prepayment of loans underlying
 asset-backed and receivables-backed securities can be expected to
 accelerate. Accordingly, a Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. In addition, securities that are backed by
 credit card, automobile and similar types of receivables generally do not
 have the benefit of a security interest in collateral that is comparable in
 quality to mortgage assets. There is the possibility that, in some cases,
 recoveries on repossessed collateral may not be available to support
 payments on these securities. In the event of a default, a Fund may suffer a
 loss if it cannot sell collateral quickly and receive the amount it is owed.
 
 Foreign Government Obligations and Related Foreign Risks. Foreign government
 obligations are U.S. dollar-denominated obligations (limited to commercial
 paper and other notes) issued or guaranteed by a foreign government or other
 entity located or organized in a foreign country that maintains a short-term
 foreign currency rating in the highest short-term ratings category by the
 requisite number of NRSROs.
 
 Investments by a Fund in foreign securities, whether issued by a foreign
 government, bank, corporation or other issuer, may present a greater degree
 of risk than investments in securities of domestic issuers because of less
 publicly-available financial and other information, less securities regula-
 tion, potential imposition of foreign withholding and other taxes, war,
 expropriation or other adverse governmental actions. Foreign banks and their
 foreign branches are not regulated by U.S. banking authorities, and gener-
 ally are not bound by the accounting, auditing and financial reporting stan-
 dards applicable to U.S. banks.
 
                                                                            3-FF

 Repurchase Agreements. Certain Funds may enter into repurchase agreements
 with primary dealers in U.S. Government securities and banks affiliated with
 primary dealers. Repurchase agreements involve the purchase of securities
 subject to the seller's agreement to repurchase them at a mutually agreed
 upon date and price. The repurchase price will exceed the original purchase
 price, the difference being income to the Fund, and will be unrelated to the
 interest rate on the purchased security.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund in connection with the repurchase agree-
 ment are less than the repurchase price and Fund's costs associated with
 delay and enforcement of the repurchase agreement. In addition, in the event
 of bankruptcy of the seller, a Fund could suffer additional losses if a
 court determines that the Fund's interest in the collateral is not enforce-
 able.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.
 
 Municipal Obligations. Municipal obligations are issued by or on behalf of
 states, territories and possessions of the United States and their political
 subdivisions, agencies, authorities and instrumentalities, and the District
 of Columbia. Municipal obligations may include fixed rate notes and similar
 debt instruments; variable and floating rate demand instruments; tax-exempt
 commercial paper; municipal bonds; and unrated notes, paper, bonds or other
 instruments.
 
 Municipal Notes and Bonds. Municipal notes include tax anticipation notes
 ("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
 ("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
 notes. Municipal bonds include general obligation bonds and revenue bonds.
 General obligation bonds are backed by the taxing power of the issuing
 municipality and are considered the safest type of municipal obligation.
 Revenue bonds are backed by the revenues of a project or facility such as
 the tolls from a toll bridge. Revenue bonds also include lease rental reve-
 nue bonds which are issued by a state or local authority for capital pro-
 jects and are secured by annual lease payments from the state or locality
 sufficient to cover debt service on the authority's obliga-

 tions. Industrial development bonds ("private activity bonds") are a spe-
 cific type of revenue bond backed by the credit and security of a private
 user and, therefore, have more potential risk. Municipal bonds may be issued
 in a variety of forms, including commercial paper, tender option bonds and
 variable and floating rate securities.
 
 Tender Option Bonds. A tender option bond is a municipal obligation (gener-
 ally held pursuant to a custodial arrangement) having a relatively long
 maturity and bearing interest at a fixed rate substantially higher than pre-
 vailing short-term, tax-exempt rates. The bond is typically issued in con-
 junction with the agreement of a third party, such as a bank, broker-dealer
 or other financial institution, pursuant to which the institution grants the
 security holder the option, at periodic intervals, to tender its securities
 to the institution. As consideration for providing the option, the financial
 institution receives periodic fees equal to the difference between the
 bond's fixed coupon rate and the rate, as determined by a remarketing or
 similar agent, that would cause the securities, coupled with the tender
 option, to trade at par on the date of such determination. Thus, after pay-
 ment of this fee, the security holder effectively holds a demand obligation
 that bears interest at the prevailing short-term, tax-exempt rate. Certain
 tender option bonds may be illiquid. An institution will normally not be
 obligated to accept tendered bonds in the event of certain defaults or a
 significant downgrading in the credit rating assigned to the issuer of the
 bond. The tender option will be taken into account in determining the matu-
 rity of the tender option bonds and a Fund's average portfolio maturity.
 There is a risk that a Fund will not be considered the owner of a tender
 option bond for federal income tax purposes, and thus will not be entitled
 to treat such interest as exempt from federal income tax.
 
 Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
 issued in anticipation of the issuer's receipt of revenues and present the
 risk that such revenues will be insufficient to satisfy the issuer's payment
 obligations. The entire amount of principal and interest on RAWs is due at
 maturity. RAWs, including those with a maturity of more than 397 days, may
 also be repackaged as instruments which include a demand feature that per-
 mits the holder to sell the RAWs to a bank or other financial institution at
 a purchase price equal to par plus accrued interest on each interest rate
 reset date.
 
 Industrial Development Bonds. Certain Funds may invest in industrial devel-
 opment bonds (private activity bonds), the interest from which would be an
 item of tax preference when distributed by a Fund as "exempt-interest divi-
 dends" to shareholders under the federal alternative minimum tax.
 
 Other Policies. Certain Funds may invest 25% or more of the value of their
 respective total assets in municipal obligations which are related in such a
 way that an
 
                                                                            5-FF
<PAGE>
 
 
 economic, business or political development or change affecting one munici-
 pal obligation would also affect the other municipal obligation. For exam-
 ple, such Funds may invest all of their respective assets in (a) municipal
 obligations the interest of which is paid solely from revenues from similar
 projects such as hospitals, electric utility systems, multi-family housing,
 nursing homes, commercial facilities (including hotels), steel companies or
 life care facilities, (b) municipal obligations whose issuers are in the
 same state, or (c) industrial development obligations. Concentration of a
 Fund's investments in these municipal obligations will subject the Fund, to
 a greater extent than if such investment was not so concentrated, to the
 risks of adverse economic, business or political developments affecting the
 particular state, industry or other area of concentration.
 
 Municipal obligations may be backed by letters of credit or other forms of
 credit enhancement issued by domestic banks or foreign banks which have a
 branch, agency or subsidiary in the United States or by other financial
 institutions. The credit quality of these banks and financial institutions
 could, therefore, cause a loss to a Fund that invests in municipal obliga-
 tions. Letters of credit and other obligations of foreign banks and finan-
 cial institutions may involve risks in addition to those of domestic obliga-
 tions. See "Foreign Government Obligations and Related Foreign Risks" above.
 In addition, the Funds may acquire securities in the form of custodial
 receipts which evidence ownership of future interest payments, principal
 payments or both on obligations of certain state and local governments and
 authorities.
 
 In order to enhance the liquidity, stability or quality of a municipal obli-
 gation, a Fund may acquire the right to sell the obligation to another party
 at a guaranteed price and date.
 
 Miscellaneous Investments and Policies
 
 Floating and Variable Rate Obligations. The Funds may purchase floating and
 variable rate obligations. The value of these obligations is generally more
 stable than that of a fixed rate obligation in response to changes in inter-
 est rate levels. Subject to the conditions for using amortized cost valua-
 tion under the Investment Company Act, a Fund may consider the maturity of a
 variable or floating rate obligation to be shorter than its ultimate stated
 maturity if the obligation is a U.S. Treasury obligation or U.S. Government
 security, if the obligation has a remaining maturity of 397 calendar days or
 less, or if the obligation has a demand feature that permits the Fund to
 receive payment at any time or at specified intervals not exceeding 397 cal-
 endar days. The issuers or financial intermediaries providing demand fea-
 tures may support their ability to purchase the obligations by obtaining
 credit with liquidity supports. These may include lines of credit, which are
 condi-

                                                                      APPENDIX A
 
 tional commitments to lend and letters of credit, which will ordinarily be
 irrevocable, both of which may be issued by domestic banks or foreign banks
 which have a branch, agency or subsidiary in the United States. A Fund may
 purchase variable or floating rate obligations from the issuers or may pur-
 chase certificates of participation, a type of floating or variable rate
 obligation, which are interests in a pool of debt obligations held by a bank
 or other financial institution.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to a Fund at the time of entering into the transac-
 tion. A forward commitment involves entering into a contract to purchase or
 sell securities for a fixed price at a future date beyond the customary set-
 tlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although a Fund would gener-
 ally purchase securities on a when-issued or forward commitment basis with
 the intention of acquiring the securities for its portfolio, a Fund may dis-
 pose of when-issued securities or forward commitments before settlement
 whenever the Investment Adviser deems it appropriate.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Investment Com-
 pany Act. These limitations include a prohibition on any Fund acquiring more
 than 3% of the voting shares of any other investment company, and a prohibi-
 tion on investing more than 5% of a Fund's total assets in securities of any
 one investment company or more than 10% of its total assets in securities of
 all investment companies. A Fund will indirectly bear its proportionate
 share of any management fees and other expenses paid by such other invest-
 ment companies. Such other investment companies will have investment objec-
 tives, policies and restrictions substantially similar to those of the
 acquiring Fund and will be subject to substantially the same risks.
 
 Illiquid Securities. Each Fund may invest up to 10% of its net assets in
 illiquid securities which cannot be disposed of in seven days in the ordi-
 nary course of business at fair value. Illiquid securities include:
 
  . Both domestic and foreign securities that are not readily marketable
  . Certain municipal leases and participation interests
  . Certain stripped mortgage-backed securities
 
                                                                            7-FF
<PAGE>
 
 
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that a
   restricted security is liquid because it is so-called "4(2) commercial
   paper" or is otherwise eligible for resale pursuant to Rule 144A under the
   Securities Act of 1933.
 
 Investing in restricted securities may decrease the liquidity of a Fund's
 portfolio.
 
 Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from
 banks for temporary or emergency purposes. A Fund may not make additional
 investments if borrowings exceed 5% of its net assets. For more information,
 see the Additional Statement.
 
 Downgraded Securities. After its purchase, a portfolio security may be
 assigned a lower rating or cease to be rated. If this occurs, a Fund may
 continue to hold the security if the Investment Adviser believes it is in
 the best interests of the Fund and its shareholders.

Special Risks and Policies Applicable to the Tax-Exempt Funds:
 
Fundamental Policies. As a matter of fundamental policy, at least 80% of each
of the net assets of each of the Tax-Exempt Diversified, Tax-Exempt California
and Tax-Exempt New York Portfolios will ordinarily be invested in municipal
obligations, the interest from which is, in the opinion of bond counsel, if
any, excluded from gross income for federal income tax purposes. In addition,
as a matter of fundamental policy, at least 65% of each of the Tax-Exempt Cali-
fornia and Tax-Exempt New York Portfolio's total assets will be invested in
California and New York municipal obligations, except in extraordinary circum-
stances.
 
For these purposes, California and New York municipal obligations are obliga-
tions issued by or on behalf of the State of California or the State of New
York, respectively, and their respective political subdivisions, agencies and
instrumentalities and the government of Puerto Rico, the U.S. Virgin Islands
and Guam, the interest from which is excluded from gross income for federal
income tax purposes and is exempt from California State personal income tax or
New York State and New York City personal income tax. Each Tax-Exempt Fund may
temporarily invest in taxable money market instruments or, in the case of the
Tax-Exempt California and New York Portfolios, in municipal obligations that
are not California or New York municipal obligations, respectively, when
acceptable California and New York municipal obligations are not available or
when the Investment Adviser believes that the market conditions dictate a
defensive posture. Investments in taxable money market instruments will be lim-
ited to those meeting the quality standards of each Tax-Exempt Fund. The Tax-
Exempt California and Tax-Exempt New York Portfolios' distributions of interest
from municipal obligations other than California and New York municipal obliga-
tions, respectively, may be subject to California and New York State and New
York City personal income taxes.
 
Risks of Investing in California and New York: The Tax-Exempt California and
Tax-Exempt New York Portfolios concentrate their investments in California and
New York municipal obligations. Consequently, these Funds are more susceptible
to factors adversely affecting issuers of California and New York municipal
obligations, and may be riskier than comparable municipal bond funds and money
market funds that do not emphasize these issuers to this degree.
 
The Tax-Exempt California Portfolio's investments can be affected by political
and economic developments within the State of California (the "State"), and by
 
                                                                           1-FFF

the financial condition of the State, its public authorities and political sub-
divisions. After suffering a severe recession in the early 1990's which caused
the State to experience financial difficulties, California's economy entered a
sustained recovery since late 1993 and the State's budget has returned to a
positive balance. California's long-term credit rating has been raised after
being reduced during the recession. To respond to its own revenue shortfalls
during the recession, the State reduced assistance to its public authorities
and political subdivisions. Cutbacks in state aid could further adversely
affect the financial condition of cities, counties and education districts
which are subject to their own fiscal constraints. California voters in the
past have passed amendments to the California Constitution and other measures
that limit the taxing and spending authority of California governmental enti-
ties, and future voter initiatives could result in adverse consequences affect-
ing California municipal obligations. Also, the ultimate fiscal effect of fed-
erally-mandated reform of welfare programs on the State and its local
governments is still to be resolved.
 
These factors, among others (including the outcome of related pending litiga-
tion), could reduce the credit standing of certain issuers of California munic-
ipal obligations. A more detailed discussion of the risks of investing in Cali-
fornia is included in the Additional Statement.
 
The Tax-Exempt New York Portfolio's investments will be affected by political
and economic developments within the State of New York (the "State"), and by
the financial conditions of the State, its public authorities and political
subdivisions, particularly the City of New York (the "City"). The State and the
City face long-term economic problems that could seriously affect their ability
and that of other issuers of New York municipal obligations to meet their
financial obligations. Certain substantial issuers of New York municipal obli-
gations (including issuers whose obligations may be acquired by the Fund) have
experienced serious financial difficulties in recent years. These difficulties
have at times jeopardized the credit standing and impaired the borrowing abili-
ties of all New York issuers and have generally contributed to higher interest
costs for their borrowings and fewer markets for their outstanding debt obliga-
tions. Although several different issues of municipal obligations of the State
and its agencies and instrumentalities and of the City have been downgraded by
S&P and Moody's in recent years, the most recent actions of S&P and Moody's
have been to place the debt obligations of the State on Credit Watch with posi-
tive implications and to upgrade the debt obligations of the City, respective-
ly. Strong demand for New York municipal obligations has also at times had the
effect of permitting New York municipal obligations to be issued with yields
relatively lower, and after issuance, to trade in the market at prices rela-
tively higher, than comparably rated municipal obligations issued by other
jurisdictions. A recurrence of the financial difficulties previously experi-
enced by certain issuers of New York municipal obligations could result in
defaults or declines in the market values of those issuers' existing obliga-
tions and,
 
2-FFF
<PAGE>
 
 
possibly, in the obligations of other issuers of New York municipal obliga-
tions. Although as of April 1, 1999 no issuers were in default with respect to
the payment of their New York municipal obligations, the occurrence of any such
default could materially affect adversely the market values and marketability
of all New York municipal obligations and, consequently, the NAV of the Fund's
holdings. A more detailed discussion of the risks of investing in New York is
included in the Additional Statement.
 
If California, New York, or any of their local governmental entities are unable
to meet their financial obligations, the corresponding Fund's income, NAV,
ability to preserve or realize appreciation of capital or liquidity could be
adversely affected. Also, neither of these Funds is a diversified fund (except
to the extent that diversification is required by Rule 2a-7 or for federal
income tax purposes). Because they may invest a larger percentage of their
assets in the securities of fewer issuers than do diversified funds, these
Funds may be exposed to greater risk in that an adverse change in the condition
of one or a small number of issuers would have a greater impact on them.

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

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

 General Investment Management Approach
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the
 Funds. Goldman Sachs Asset Management is referred to in this Prospectus as
 the "Investment Adviser."
 
 
 Goldman Sachs' Money Market Investment Philosophy
 The Money Market Funds are managed to seek maximum current income consistent
 with the preservation of capital and daily liquidity. In managing the Funds,
 the Investment Adviser follows a conservative, risk-managed investment proc-
 ess that seeks to:
..Manage credit risk
..Manage interest rate risk
..Manage liquidity
 
 The Investment Adviser actively manages the Goldman Sachs Money Market Funds
 in designing and structuring the Fund's investment portfolios.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 The Investment Adviser follows a consistent five-step investment process
 across all of its money market portfolios.
 
 1. Define investment objectives and risk parameters
 The Investment Adviser works closely within Fund and Rule 2a-7 guidelines in
 seeking to meet investment objectives for each Fund.
 
 2. Establish benchmarks
 Benchmarks are the IBC Financial Data Universal Averages. Depending upon the
 eligible investments of each Fund, there is a corresponding IBC Index.
 
 3. Establish a risk-managed framework
 Understanding and managing risk is critical to the performance of money mar-
 ket fund portfolios.
 
 4. Actively manage the portfolios
 General portfolio strategy meetings are held weekly.
 
 5. Monitor Risk Exposure
 Risk reports enable the Investment Adviser to monitor portfolios on a daily
 basis and track all trading activity.
 
                                                                            1-KK

..The Funds: Each Fund's securities are valued by the amortized cost method as
  permitted under Rule 2a-7 of the Investment Company Act of 1940, as amended
  (the "1940 Act"). Under Rule 2a-7, each Fund may invest only in U.S. dollar
  denominated securities that are determined to present minimal credit risk
  and meet certain other criteria including those conditions relating to matu-
  rity, diversification and credit quality. These operating policies may be
  more restrictive than the fundamental policies set forth in the Statement of
  Additional Information (the "Additional Statement").
 
   .Taxable Funds: Prime Obligations, Money Market, Treasury Obligations and
    Government Portfolios.
    .Tax-Advantaged Funds: Treasury Instruments and Federal Portfolios.
   .Tax-Exempt Funds: Tax-Exempt Diversified, Tax-Exempt California and Tax-
    Exempt New York Portfolios.
..The Investors: The Funds are designed for investors seeking a high rate of
  return, a stable net asset value ("NAV") and convenient liquidation privi-
  leges. The Funds are particularly suitable for banks, corporations and other
  financial institutions that seek investment of short-term funds for their
  own accounts or for the accounts of their customers.
..NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
..Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
..Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
..Investment Restrictions: Each Fund is subject to certain investment restric-
  tions that are described in detail under "Investment Restrictions" in the
  Additional Statement. Fundamental investment restrictions and the investment
  objective of a Fund (except the Tax-Exempt California and Tax-Exempt New
  York Portfolios' objectives of providing shareholders with income exempt
  from California State and New York State and New York City personal income
  tax, respectively) cannot be changed without approval of a majority of the
  outstanding shares of that Fund. The Treasury Obligations Portfolio's policy
  of limiting its investments to U.S. Treasury Obligations and related repur-
  chase agreements is also fundamental. All investment policies not specifi-
  cally designated as fundamental are non-fundamental and may be changed with-

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
  (the "SEC"), each Fund may not invest more than 5% of the value of its total
  assets at the time of purchase in the securities of any single issuer with
  these exceptions: (a) the Tax-Exempt California and Tax-Exempt New York
  Portfolios may each invest up to 25% of their total assets in five or fewer
  issuers; and (b) each of the other Funds may invest up to 25% of its total
  assets in the securities of a single issuer for up to three business days.
  These limitations do not apply to cash, certain repurchase agreements, U.S.
  Government securities or securities of other investment companies. In addi-
  tion, securities subject to certain unconditional guarantees and securities
  that are not "First Tier Securities" as defined by the SEC are subject to
  different diversification requirements as described in the Additional State-
  ment.

 Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Treasury Obligations, Treasury Instru-
 ments, Government and Federal Portfolios seek to maximize current income to
 the extent consistent with the preservation of capital and the maintenance
 of liquidity by investing exclusively in high quality money market instru-
 ments.
 
 The Treasury Instruments and Federal Portfolios pursue their investment
 objectives by limiting their investments to certain U.S. Treasury obliga-
 tions and U.S. Government securities (each as defined in Appendix A),
 respectively, the interest from which is generally exempt from state income
 taxation. You should consult your tax adviser to determine whether distribu-
 tions from the Treasury Instruments and Federal Portfolios (and any other
 Fund that may hold such obligations) derived from interest on such obliga-
 tions are exempt from state income taxation in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
 Portfolios seek to provide shareholders, to the extent consistent with the
 preservation of capital and prescribed portfolio standards, with a high
 level of income exempt from federal income tax by investing primarily in
 municipal instruments.
 
 In addition, the Tax-Exempt California and Tax-Exempt New York Portfolios
 seek to provide shareholders with income exempt from California State and
 New York State and City personal income taxes, respectively.
 
 The Tax-Exempt Funds pursue their investment objectives by limiting their
 investments to securities issued by or on behalf of states, territories, and
 possessions of the United States and their political subdivisions, agencies,
 authorities and instrumentalities, and the District of Columbia, the inter-
 est from which, if any, is in the opinion of bond counsel excluded from
 gross income for federal income tax purposes, and not an item of tax prefer-
 ence under the federal alternative minimum tax.

 /1/If adverse economic conditions prevail in the banking industry (such as
   substantial losses on loans, increases in non-performing assets and
   charge-offs and declines in total deposits), the Fund may, for temporary
   defensive purposes, invest less than 25% of its total assets in bank
   obligations.
 /2/To the extent required by Rule 2a-7, asset-backed and receivables-backed
   securities will be rated by the requisite number of nationally recognized
   statistical rating organizations ("NRSROs").
 /3/U.S. Treasury Obligations are securities issued by the U.S. Treasury.
 /4/U.S. Treasury Obligations are securities issued or guaranteed by the U.S.

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

Risks that apply to all Funds:
 
..Money Market Risk--The risk that a Fund will not be able to maintain a NAV
  per share of $1.00 at all times.
..Interest Rate Risk--The risk that during periods of rising interest rates,
  a Fund's yield (and the market value of its securities) will tend to be
  lower than prevailing market rates; in periods of falling interest rates, a
  Fund's yield will tend to be higher.
..Credit/Default Risk--The risk that an issuer or guarantor of a security, or
  a bank or other financial institution that has entered into a repurchase
  agreement, may default on its payment obligations.
..Management Risk--The risk that a strategy used by the Investment Adviser
  may fail to produce the intended results.
..Liquidity Risk--The risk that a Fund will be unable to pay redemption pro-
  ceeds within the time period stated in this Prospectus, because of either
  unusual market conditions, an unusually high volume of redemption requests,
  or other reasons.
..Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by
  the "Year 2000 Problem."
 
Risk that applies to the Government and Federal Portfolios:
 
..Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market, Tax-Exempt Diversified, Tax-Exempt
California and Tax-Exempt New York Portfolios:
 
..Concentration Risk--The risk that if a Fund invests more than 25% of its
  total assets in issuers within the same state, industry or economic sector,
  an adverse economic, business or political development may affect the value
  of the Fund's investments more than if its investments were not so concen-
  trated.
..Foreign Risk--The risk that a foreign security (or, in the case of the Tax-
  Exempt California and Tax-Exempt New York Portfolio, a foreign letter of
  credit or guarantee) could lose value as a result of political, financial
  and economic events in foreign countries, less stringent foreign securities
  regulations and accounting and disclosure standards, or other factors. The
  Money Market Portfolio may not invest more than 25% of its total assets in
  the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
Risk that applies to the Money Market Portfolio:
 
..Banking Industry Risk--The risk that if a Fund invests more than 25% of its
  total assets in bank obligations, an adverse development in the banking
  industry may affect the value of the Fund's investments more than if a
  Fund's investments were not invested to such a degree in the banking indus-
  try. Normally, the Money Market Portfolio intends to invest more than 25%
  of its total assets in bank obligations, and the Tax-Exempt California and
  Tax-Exempt New York Portfolio intend to invest at least 65% of their total
  assets in California municipal obligations and New York municipal obliga-
  tions, respectively. Banks may be particularly susceptible to certain eco-
  nomic factors such as interest rate changes, adverse developments in the
  real estate market, fiscal and monetary policy and general economic cycles.
 
Risk that applies to the Tax-Exempt Funds:
 
..Tax Risk--The risk that future legislative or administrative changes or
  court decisions may materially affect the ability of a Fund to pay federal
  tax-exempt dividends (in the case of each of these Funds) and state tax-
  exempt dividends (in the case of the Tax-Exempt California and Tax-Exempt
  New York Funds).
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Admin-
 istration Shares from year to year; and (b) how the average annual returns
 of a Fund's Administration Shares compare to the returns of a composite of
 mutual funds with similar investment objectives. The bar chart and table
 assume reinvestment of dividends and distributions. A Fund's past perfor-
 mance is not necessarily an indication of how the Fund will perform in the
 future. Performance reflects expense limitations in effect. If expense limi-
 tations were not in place, a Fund's performance would have been reduced. You
 may obtain a Fund's current yield by calling 1-800-621-2550.

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

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

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled.
 
 The Investment Adviser has voluntarily agreed to reduce or otherwise limit
 the daily expenses of each Fund (excluding fees payable under service,
 administration and distribution plans for certain share classes, taxes,
 interest, brokerage and litigation, indemnification and other extraordinary
 expenses) on an annualized basis to 0.43% of the average daily net assets of
 the Fund. Such reductions or limits, if any, are calculated monthly on a
 cumulative basis. These reductions or limits may be discontinued or modified
 only with the express approval of the Trustees.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606, also serves as the Fund's
 transfer agent (the "Transfer Agent") and as such, performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," which may lead to computer shutdowns or
 errors (commonly known as the "Year 2000 Problem"). To the extent these sys-
 tems conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.

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

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

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

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

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

 business day, and the order will be priced at the Fund's NAV next determined
 after such acceptance.
..Service Organizations or intermediaries will be responsible for transmitting
 accepted orders and payments to the Trust within the time period agreed upon
 by them.
 
You should contact your Service Organization directly to learn whether it is
authorized to accept orders for the Trust.
 
Pursuant to an administration plan adopted by the Trust's Board of Trustees,
Service Organizations are entitled to receive payments for their services from
the Trust of up to 0.15% (on an annualized basis) of the average daily net
assets of the Administration Shares of the Funds, which are attributable to or
held in the name of the Service Organization for its customers. In addition,
GSAM, at its own expense, may pay a Service Organization, up to 0.10% of the
average daily net assets of the Administration Shares of the Fund, which are
attributable to or held in the name of the Service Organization for its custom-
ers. Such compensation does not represent an additional expense to a Fund or
its shareholders, since it will be paid from the assets of GSAM.
 
The Investment Adviser, Distributor and/or their affiliates may pay additional
compensation from time to time, out of their assets and not as an additional
charge to the Funds, to selected Service Organizations and other persons in
connection with the sale, distribution and/or servicing of shares of the Funds
and other Goldman Sachs Funds. Subject to applicable NASD regulations, the
Investment Adviser, Distributor and/or their affiliates may also contribute to
various cash and non-cash incentive arrangements to promote the sale of shares.
This additional compensation can vary among Service Organizations depending
upon such factors as the amounts their customers have invested (or may invest)
in particular Goldman Sachs Funds, the particular program involved, or the
amount of reimbursable expenses.
 
In addition to Administration Shares, each Fund also offers other classes of
shares to investors. These other share classes are subject to different fees
and expenses (which affect performance), have different minimum investment
requirements and are entitled to different services than Administration Shares.
Information regarding these other share classes may be obtained from your sales
representative or from Goldman Sachs by calling the number on the back cover of
this Prospectus.
 
What Is My Minimum Investment In The Funds?
The Funds do not have any minimum purchase or account requirements with respect
to Administration Shares. A Service Organization may, however, impose a minimum
amount for initial and subsequent investments in Administration Shares, and may
establish other requirements such as a minimum account balance. A Service
Organization may redeem Administration Shares held by non-complying accounts,
and may impose a charge for any special services.
 
                                                                            3-PP
<PAGE>
 
 
 
What Else Should I Know About Share Purchases?
The Trust reserves the right to:
..Modify or waive the minimum investment and minimum account balance require-
 ment.
..Reject any purchase order for any reason.
 
The Funds may allow Service Organizations to purchase shares with securities
instead of cash if consistent with a Fund's investment policies and operations
and if approved by the Fund's Investment Adviser.
 
How Are Shares Priced?
The price you pay or receive when you buy, sell or exchange Administration
Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
..NAV per share of each class is calculated by State Street on each business day
 as of the close of regular trading on the New York Stock Exchange (usually
 4:00 p.m. New York time). Fund Shares will be priced on any day the New York
 Stock Exchange is open, except for days on which Chicago, Boston or New York
 banks are closed for local holidays.
..On any business day when the Bond Market Association ("BMA") recommends that
 the securities markets close early, each Fund reserves the right to close at
 or prior to the BMA recommended closing time. If a Fund does so, it will cease
 granting same business day credit for purchase and redemption orders received
 after the Fund's closing time and credit will be given to the next business
 day.
..The Trust reserves the right to advance the time by which purchase and redemp-
 tion orders must be received for same business day credit as permitted by the
 SEC.
 
To help each Fund maintain its $1.00 constant share price, portfolio securities
are valued at amortized cost in accordance with SEC regulations. Amortized cost
will normally approximate market value. There can be no assurance that a Fund
will be able at all times to maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 How Can I Sell Administration Shares Of The Funds?
 Generally, Administration Shares may be sold (redeemed) only through Service
 Organizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. Generally,
 each Fund will

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

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

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

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

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

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

Dividends
 
 All or substantially all of each Fund's net investment income will be
 declared as a dividend daily. Dividends will normally, but not always, be
 declared as of 4:00 p.m. New York time as a dividend and distributed to
 Service Organizations monthly. Service Organizations may choose to have div-
 idends paid in:
..Cash
..Additional shares of the same class of the same Fund
 
 Service Organizations may indicate their election on the Account Applica-
 tion. Any changes may be submitted in writing to Goldman Sachs at any time.
 If a Service Organization does not indicate any choice, dividends and dis-
 tributions will be reinvested automatically in the applicable Fund.
 
 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and December may be distributed during the
 subsequent calendar year. Although realized gains and losses on the assets
 of a Fund are reflected in the NAV of the Fund, they are not expected to be
 of an amount which would affect the Fund's NAV of $1.00 per share.
 
 The income declared as a dividend for the Treasury Obligations and Govern-
 ment Portfolios is based on estimates of net investment income for each
 Fund. Actual income may differ from estimates, and differences, if any, will
 be included in the calculation of subsequent dividends.

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

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

                                                                      APPENDIX A
 
 larly susceptible to certain economic factors, such as interest rate changes
 and adverse developments in the real estate markets. Fiscal and monetary
 policy and general economic cycles can affect the availability and cost of
 funds, loan demand and asset quality and thereby impact the earnings and
 financial conditions of banks.
 
 Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
 asset-backed and receivables-backed securities, whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed and receivables-backed securities are often subject to more
 rapid repayment than their stated maturity date would indicate as a result
 of the pass-through of prepayments of principal on the underlying loans.
 During periods of declining interest rates, prepayment of loans underlying
 asset-backed and receivables-backed securities can be expected to
 accelerate. Accordingly, a Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. In addition, securities that are backed by
 credit card, automobile and similar types of receivables generally do not
 have the benefit of a security interest in collateral that is comparable in
 quality to mortgage assets. There is the possibility that, in some cases,
 recoveries on repossessed collateral may not be available to support
 payments on these securities. In the event of a default, a Fund may suffer a
 loss if it cannot sell collateral quickly and receive the amount it is owed.
 
 Foreign Government Obligations and Related Foreign Risks. Foreign government
 obligations are U.S. dollar-denominated obligations (limited to commercial
 paper and other notes) issued or guaranteed by a foreign government or other
 entity located or organized in a foreign country that maintains a short-term
 foreign currency rating in the highest short-term ratings category by the
 requisite number of NRSROs.
 
 Investments by a Fund in foreign securities, whether issued by a foreign
 government, bank, corporation or other issuer, may present a greater degree
 of risk than investments in securities of domestic issuers because of less
 publicly-available financial and other information, less securities regula-
 tion, potential imposition of foreign withholding and other taxes, war,
 expropriation or other adverse governmental actions. Foreign banks and their
 foreign branches are not regulated by U.S. banking authorities, and gener-
 ally are not bound by the accounting, auditing and financial reporting stan-
 dards applicable to U.S. banks.
 
                                                                            3-FF
<PAGE>
 
 
 
 Repurchase Agreements. Certain Funds may enter into repurchase agreements
 with primary dealers in U.S. Government securities and banks affiliated with
 primary dealers. Repurchase agreements involve the purchase of securities
 subject to the seller's agreement to repurchase them at a mutually agreed
 upon date and price. The repurchase price will exceed the original purchase
 price, the difference being income to the Fund, and will be unrelated to the
 interest rate on the purchased security.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund in connection with the repurchase agree-
 ment are less than the repurchase price and Fund's costs associated with
 delay and enforcement of the repurchase agreement. In addition, in the event
 of bankruptcy of the seller, a Fund could suffer additional losses if a
 court determines that the Fund's interest in the collateral is not enforce-
 able.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.
 
 Municipal Obligations. Municipal obligations are issued by or on behalf of
 states, territories and possessions of the United States and their political
 subdivisions, agencies, authorities and instrumentalities, and the District
 of Columbia. Municipal obligations may include fixed rate notes and similar
 debt instruments; variable and floating rate demand instruments; tax-exempt
 commercial paper; municipal bonds; and unrated notes, paper, bonds or other
 instruments.
 
 Municipal Notes and Bonds. Municipal notes include tax anticipation notes
 ("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
 ("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
 notes. Municipal bonds include general obligation bonds and revenue bonds.
 General obligation bonds are backed by the taxing power of the issuing
 municipality and are considered the safest type of municipal obligation.
 Revenue bonds are backed by the revenues of a project or facility such as
 the tolls from a toll bridge. Revenue bonds also include lease rental reve-
 nue bonds which are issued by a state or local authority for capital pro-
 jects and are secured by annual lease payments from the state or locality
 sufficient to cover debt service on the authority's obliga-

                                                                      APPENDIX A
 
 tions. Industrial development bonds ("private activity bonds") are a spe-
 cific type of revenue bond backed by the credit and security of a private
 user and, therefore, have more potential risk. Municipal bonds may be issued
 in a variety of forms, including commercial paper, tender option bonds and
 variable and floating rate securities.
 
 Tender Option Bonds. A tender option bond is a municipal obligation (gener-
 ally held pursuant to a custodial arrangement) having a relatively long
 maturity and bearing interest at a fixed rate substantially higher than pre-
 vailing short-term, tax-exempt rates. The bond is typically issued in con-
 junction with the agreement of a third party, such as a bank, broker-dealer
 or other financial institution, pursuant to which the institution grants the
 security holder the option, at periodic intervals, to tender its securities
 to the institution. As consideration for providing the option, the financial
 institution receives periodic fees equal to the difference between the
 bond's fixed coupon rate and the rate, as determined by a remarketing or
 similar agent, that would cause the securities, coupled with the tender
 option, to trade at par on the date of such determination. Thus, after pay-
 ment of this fee, the security holder effectively holds a demand obligation
 that bears interest at the prevailing short-term, tax-exempt rate. Certain
 tender option bonds may be illiquid. An institution will normally not be
 obligated to accept tendered bonds in the event of certain defaults or a
 significant downgrading in the credit rating assigned to the issuer of the
 bond. The tender option will be taken into account in determining the matu-
 rity of the tender option bonds and a Fund's average portfolio maturity.
 There is a risk that a Fund will not be considered the owner of a tender
 option bond for federal income tax purposes, and thus will not be entitled
 to treat such interest as exempt from federal income tax.
 
 Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
 issued in anticipation of the issuer's receipt of revenues and present the
 risk that such revenues will be insufficient to satisfy the issuer's payment
 obligations. The entire amount of principal and interest on RAWs is due at
 maturity. RAWs, including those with a maturity of more than 397 days, may
 also be repackaged as instruments which include a demand feature that per-
 mits the holder to sell the RAWs to a bank or other financial institution at
 a purchase price equal to par plus accrued interest on each interest rate
 reset date.
 
 Industrial Development Bonds. Certain Funds may invest in industrial devel-
 opment bonds (private activity bonds), the interest from which would be an
 item of tax preference when distributed by a Fund as "exempt-interest divi-
 dends" to shareholders under the federal alternative minimum tax.
 
 Other Policies. Certain Funds may invest 25% or more of the value of their
 respective total assets in municipal obligations which are related in such a
 way that an
 
                                                                            5-FF
<PAGE>
 
 
 economic, business or political development or change affecting one munici-
 pal obligation would also affect the other municipal obligation. For exam-
 ple, such Funds may invest all of their respective assets in (a) municipal
 obligations the interest of which is paid solely from revenues from similar
 projects such as hospitals, electric utility systems, multi-family housing,
 nursing homes, commercial facilities (including hotels), steel companies or
 life care facilities, (b) municipal obligations whose issuers are in the
 same state, or (c) industrial development obligations. Concentration of a
 Fund's investments in these municipal obligations will subject the Fund, to
 a greater extent than if such investment was not so concentrated, to the
 risks of adverse economic, business or political developments affecting the
 particular state, industry or other area of concentration.
 
 Municipal obligations may be backed by letters of credit or other forms of
 credit enhancement issued by domestic banks or foreign banks which have a
 branch, agency or subsidiary in the United States or by other financial
 institutions. The credit quality of these banks and financial institutions
 could, therefore, cause a loss to a Fund that invests in municipal obliga-
 tions. Letters of credit and other obligations of foreign banks and finan-
 cial institutions may involve risks in addition to those of domestic obliga-
 tions. See "Foreign Government Obligations and Related Foreign Risks" above.
 In addition, the Funds may acquire securities in the form of custodial
 receipts which evidence ownership of future interest payments, principal
 payments or both on obligations of certain state and local governments and
 authorities.
 
 In order to enhance the liquidity, stability or quality of a municipal obli-
 gation, a Fund may acquire the right to sell the obligation to another party
 at a guaranteed price and date.
 
 Miscellaneous Investments and Policies
 
 Floating and Variable Rate Obligations. The Funds may purchase floating and
 variable rate obligations. The value of these obligations is generally more
 stable than that of a fixed rate obligation in response to changes in inter-
 est rate levels. Subject to the conditions for using amortized cost valua-
 tion under the Investment Company Act, a Fund may consider the maturity of a
 variable or floating rate obligation to be shorter than its ultimate stated
 maturity if the obligation is a U.S. Treasury obligation or U.S. Government
 security, if the obligation has a remaining maturity of 397 calendar days or
 less, or if the obligation has a demand feature that permits the Fund to
 receive payment at any time or at specified intervals not exceeding 397 cal-
 endar days. The issuers or financial intermediaries providing demand fea-
 tures may support their ability to purchase the obligations by obtaining
 credit with liquidity supports. These may include lines of credit, which are
 condi-

                                                                      APPENDIX A
 
 tional commitments to lend and letters of credit, which will ordinarily be
 irrevocable, both of which may be issued by domestic banks or foreign banks
 which have a branch, agency or subsidiary in the United States. A Fund may
 purchase variable or floating rate obligations from the issuers or may pur-
 chase certificates of participation, a type of floating or variable rate
 obligation, which are interests in a pool of debt obligations held by a bank
 or other financial institution.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to a Fund at the time of entering into the transac-
 tion. A forward commitment involves entering into a contract to purchase or
 sell securities for a fixed price at a future date beyond the customary set-
 tlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although a Fund would gener-
 ally purchase securities on a when-issued or forward commitment basis with
 the intention of acquiring the securities for its portfolio, a Fund may dis-
 pose of when-issued securities or forward commitments before settlement
 whenever the Investment Adviser deems it appropriate.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Investment Com-
 pany Act. These limitations include a prohibition on any Fund acquiring more
 than 3% of the voting shares of any other investment company, and a prohibi-
 tion on investing more than 5% of a Fund's total assets in securities of any
 one investment company or more than 10% of its total assets in securities of
 all investment companies. A Fund will indirectly bear its proportionate
 share of any management fees and other expenses paid by such other invest-
 ment companies. Such other investment companies will have investment objec-
 tives, policies and restrictions substantially similar to those of the
 acquiring Fund and will be subject to substantially the same risks.
 
 Illiquid Securities. Each Fund may invest up to 10% of its net assets in
 illiquid securities which cannot be disposed of in seven days in the ordi-
 nary course of business at fair value. Illiquid securities include:
 
  . Both domestic and foreign securities that are not readily marketable
  . Certain municipal leases and participation interests
  . Certain stripped mortgage-backed securities
 
                                                                            7-FF
<PAGE>
 
 
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that a
   restricted security is liquid because it is so-called "4(2) commercial
   paper" or is otherwise eligible for resale pursuant to Rule 144A under the
   Securities Act of 1933.
 
 Investing in restricted securities may decrease the liquidity of a Fund's
 portfolio.
 
 Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from
 banks for temporary or emergency purposes. A Fund may not make additional
 investments if borrowings exceed 5% of its net assets. For more information,
 see the Additional Statement.
 
 Downgraded Securities. After its purchase, a portfolio security may be
 assigned a lower rating or cease to be rated. If this occurs, a Fund may
 continue to hold the security if the Investment Adviser believes it is in
 the best interests of the Fund and its shareholders.

Special Risks and Policies Applicable to the Tax-Exempt Funds:
 
Fundamental Policies. As a matter of fundamental policy, at least 80% of each
of the net assets of each of the Tax-Exempt Diversified, Tax-Exempt California
and Tax-Exempt New York Portfolios will ordinarily be invested in municipal
obligations, the interest from which is, in the opinion of bond counsel, if
any, excluded from gross income for federal income tax purposes. In addition,
as a matter of fundamental policy, at least 65% of each of the Tax-Exempt Cali-
fornia and Tax-Exempt New York Portfolio's total assets will be invested in
California and New York municipal obligations, except in extraordinary circum-
stances.
 
For these purposes, California and New York municipal obligations are obliga-
tions issued by or on behalf of the State of California or the State of New
York, respectively, and their respective political subdivisions, agencies and
instrumentalities and the government of Puerto Rico, the U.S. Virgin Islands
and Guam, the interest from which is excluded from gross income for federal
income tax purposes and is exempt from California State personal income tax or
New York State and New York City personal income tax. Each Tax-Exempt Fund may
temporarily invest in taxable money market instruments or, in the case of the
Tax-Exempt California and New York Portfolios, in municipal obligations that
are not California or New York municipal obligations, respectively, when
acceptable California and New York municipal obligations are not available or
when the Investment Adviser believes that the market conditions dictate a
defensive posture. Investments in taxable money market instruments will be lim-
ited to those meeting the quality standards of each Tax-Exempt Fund. The Tax-
Exempt California and Tax-Exempt New York Portfolios' distributions of interest
from municipal obligations other than California and New York municipal obliga-
tions, respectively, may be subject to California and New York State and New
York City personal income taxes.
 
Risks of Investing in California and New York: The Tax-Exempt California and
Tax-Exempt New York Portfolios concentrate their investments in California and
New York municipal obligations. Consequently, these Funds are more susceptible
to factors adversely affecting issuers of California and New York municipal
obligations, and may be riskier than comparable municipal bond funds and money
market funds that do not emphasize these issuers to this degree.
 
The Tax-Exempt California Portfolio's investments can be affected by political
and economic developments within the State of California (the "State"), and by
 
                                                                           1-FFF
<PAGE>
 
 
the financial condition of the State, its public authorities and political sub-
divisions. After suffering a severe recession in the early 1990's which caused
the State to experience financial difficulties, California's economy entered a
sustained recovery since late 1993 and the State's budget has returned to a
positive balance. California's long-term credit rating has been raised after
being reduced during the recession. To respond to its own revenue shortfalls
during the recession, the State reduced assistance to its public authorities
and political subdivisions. Cutbacks in state aid could further adversely
affect the financial condition of cities, counties and education districts
which are subject to their own fiscal constraints. California voters in the
past have passed amendments to the California Constitution and other measures
that limit the taxing and spending authority of California governmental enti-
ties, and future voter initiatives could result in adverse consequences affect-
ing California municipal obligations. Also, the ultimate fiscal effect of fed-
erally-mandated reform of welfare programs on the State and its local
governments is still to be resolved.
 
These factors, among others (including the outcome of related pending litiga-
tion), could reduce the credit standing of certain issuers of California munic-
ipal obligations. A more detailed discussion of the risks of investing in Cali-
fornia is included in the Additional Statement.
 
The Tax-Exempt New York Portfolio's investments will be affected by political
and economic developments within the State of New York (the "State"), and by
the financial conditions of the State, its public authorities and political
subdivisions, particularly the City of New York (the "City"). The State and the
City face long-term economic problems that could seriously affect their ability
and that of other issuers of New York municipal obligations to meet their
financial obligations. Certain substantial issuers of New York municipal obli-
gations (including issuers whose obligations may be acquired by the Fund) have
experienced serious financial difficulties in recent years. These difficulties
have at times jeopardized the credit standing and impaired the borrowing abili-
ties of all New York issuers and have generally contributed to higher interest
costs for their borrowings and fewer markets for their outstanding debt obliga-
tions. Although several different issues of municipal obligations of the State
and its agencies and instrumentalities and of the City have been downgraded by
S&P and Moody's in recent years, the most recent actions of S&P and Moody's
have been to place the debt obligations of the State on Credit Watch with posi-
tive implications and to upgrade the debt obligations of the City, respective-
ly. Strong demand for New York municipal obligations has also at times had the
effect of permitting New York municipal obligations to be issued with yields
relatively lower, and after issuance, to trade in the market at prices rela-
tively higher, than comparably rated municipal obligations issued by other
jurisdictions. A recurrence of the financial difficulties previously experi-
enced by certain issuers of New York municipal obligations could result in
defaults or declines in the market values of those issuers' existing obliga-
tions and,
 
2-FFF
<PAGE>
 
 
possibly, in the obligations of other issuers of New York municipal obliga-
tions. Although as of April 1, 1999 no issuers were in default with respect to
the payment of their New York municipal obligations, the occurrence of any such
default could materially affect adversely the market values and marketability
of all New York municipal obligations and, consequently, the NAV of the Fund's
holdings. A more detailed discussion of the risks of investing in New York is
included in the Additional Statement.
 
If California, New York, or any of their local governmental entities are unable
to meet their financial obligations, the corresponding Fund's income, NAV,
ability to preserve or realize appreciation of capital or liquidity could be
adversely affected. Also, neither of these Funds is a diversified fund (except
to the extent that diversification is required by Rule 2a-7 or for federal
income tax purposes). Because they may invest a larger percentage of their
assets in the securities of fewer issuers than do diversified funds, these
Funds may be exposed to greater risk in that an adverse change in the condition
of one or a small number of issuers would have a greater impact on them.

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

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

 General Investment Management Approach
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the
 Funds. Goldman Sachs Asset Management is referred to in this Prospectus as
 the "Investment Adviser."
 
 
 Goldman Sachs' Money Market Investment Philosophy
 The Money Market Funds are managed to seek maximum current income consistent
 with the preservation of capital and daily liquidity. In managing the Funds,
 the Investment Adviser follows a conservative, risk-managed investment proc-
 ess that seeks to:
..Manage credit risk
..Manage interest rate risk
..Manage liquidity
 
 The Investment Adviser actively manages the Goldman Sachs Money Market Funds
 in designing and structuring the Fund's investment portfolios.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 The Investment Adviser follows a consistent five-step investment process
 across all of its money market portfolios.
 
 1. Define investment objectives and risk parameters
 The Investment Adviser works closely within Fund and Rule 2a-7 guidelines in
 seeking to meet investment objectives for each Fund.
 
 2. Establish benchmarks
 Benchmarks are the IBC Financial Data Universal Averages. Depending upon the
 eligible investments of each Fund, there is a corresponding IBC Index.
 
 3. Establish a risk-managed framework
 Understanding and managing risk is critical to the performance of money mar-
 ket fund portfolios.
 
 4. Actively manage the portfolios
 General portfolio strategy meetings are held weekly.
 
 5. Monitor Risk Exposure
 Risk reports enable the Investment Adviser to monitor portfolios on a daily
 basis and track all trading activity.
 
                                                                            1-KK

..The Funds: Each Fund's securities are valued by the amortized cost method as
  permitted under Rule 2a-7 of the Investment Company Act of 1940, as amended
  (the "1940 Act"). Under Rule 2a-7, each Fund may invest only in U.S. dollar
  denominated securities that are determined to present minimal credit risk
  and meet certain other criteria including those conditions relating to matu-
  rity, diversification and credit quality. These operating policies may be
  more restrictive than the fundamental policies set forth in the Statement of
  Additional Information (the "Additional Statement").
 
   .Taxable Funds: Prime Obligations, Money Market, Treasury Obligations and
    Government Portfolios.
    .Tax-Advantaged Funds: Treasury Instruments and Federal Portfolios.
   .Tax-Exempt Funds: Tax-Exempt Diversified, Tax-Exempt California and Tax-
    Exempt New York Portfolios.
..The Investors: The Funds are designed for investors seeking a high rate of
  return, a stable net asset value ("NAV") and convenient liquidation privi-
  leges. The Funds are particularly suitable for banks, corporations and other
  financial institutions that seek investment of short-term funds for their
  own accounts or for the accounts of their customers.
..NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
..Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
..Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
..Investment Restrictions: Each Fund is subject to certain investment restric-
  tions that are described in detail under "Investment Restrictions" in the
  Additional Statement. Fundamental investment restrictions and the investment
  objective of a Fund (except the Tax-Exempt California and Tax-Exempt New
  York Portfolios' objectives of providing shareholders with income exempt
  from California State and New York State and New York City personal income
  tax, respectively) cannot be changed without approval of a majority of the
  outstanding shares of that Fund. The Treasury Obligations Portfolio's policy
  of limiting its investments to U.S. Treasury Obligations and related repur-
  chase agreements is also fundamental. All investment policies not specifi-
  cally designated as fundamental are non-fundamental and may be changed with-
  out shareholder approval.
..Diversification. Diversification can help a Fund reduce the risks of invest-
  ing. In accordance with current regulations of the Securities and Exchange
  Commission

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
  (the "SEC"), each Fund may not invest more than 5% of the value of its total
  assets at the time of purchase in the securities of any single issuer with
  these exceptions: (a) the Tax-Exempt California and Tax-Exempt New York
  Portfolios may each invest up to 25% of their total assets in five or fewer
  issuers; and (b) each of the other Funds may invest up to 25% of its total
  assets in the securities of a single issuer for up to three business days.
  These limitations do not apply to cash, certain repurchase agreements, U.S.
  Government securities or securities of other investment companies. In addi-
  tion, securities subject to certain unconditional guarantees and securities
  that are not "First Tier Securities" as defined by the SEC are subject to
  different diversification requirements as described in the Additional State-
  ment.
 
                                                                            3-KK

 Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Treasury Obligations, Treasury Instru-
 ments, Government and Federal Portfolios seek to maximize current income to
 the extent consistent with the preservation of capital and the maintenance
 of liquidity by investing exclusively in high quality money market instru-
 ments.
 
 The Treasury Instruments and Federal Portfolios pursue their investment
 objectives by limiting their investments to certain U.S. Treasury obliga-
 tions and U.S. Government securities (each as defined in Appendix A),
 respectively, the interest from which is generally exempt from state income
 taxation. You should consult your tax adviser to determine whether distribu-
 tions from the Treasury Instruments and Federal Portfolios (and any other
 Fund that may hold such obligations) derived from interest on such obliga-
 tions are exempt from state income taxation in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
 Portfolios seek to provide shareholders, to the extent consistent with the
 preservation of capital and prescribed portfolio standards, with a high
 level of income exempt from federal income tax by investing primarily in
 municipal instruments.
 
 In addition, the Tax-Exempt California and Tax-Exempt New York Portfolios
 seek to provide shareholders with income exempt from California State and
 New York State and City personal income taxes, respectively.
 
 The Tax-Exempt Funds pursue their investment objectives by limiting their
 investments to securities issued by or on behalf of states, territories, and
 possessions of the United States and their political subdivisions, agencies,
 authorities and instrumentalities, and the District of Columbia, the inter-
 est from which, if any, is in the opinion of bond counsel excluded from
 gross income for federal income tax purposes, and not an item of tax prefer-
 ence under the federal alternative minimum tax.

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

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

Risks that apply to all Funds:
 
..Money Market Risk--The risk that a Fund will not be able to maintain a NAV
  per share of $1.00 at all times.
..Interest Rate Risk--The risk that during periods of rising interest rates,
  a Fund's yield (and the market value of its securities) will tend to be
  lower than prevailing market rates; in periods of falling interest rates, a
  Fund's yield will tend to be higher.
..Credit/Default Risk--The risk that an issuer or guarantor of a security, or
  a bank or other financial institution that has entered into a repurchase
  agreement, may default on its payment obligations.
..Management Risk--The risk that a strategy used by the Investment Adviser
  may fail to produce the intended results.
..Liquidity Risk--The risk that a Fund will be unable to pay redemption pro-
  ceeds within the time period stated in this Prospectus, because of either
  unusual market conditions, an unusually high volume of redemption requests,
  or other reasons.
..Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by
  the "Year 2000 Problem."
 
Risk that applies to the Government and Federal Portfolios:
 
..Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market, Tax-Exempt Diversified, Tax-Exempt
California and Tax-Exempt New York Portfolios:
 
..Concentration Risk--The risk that if a Fund invests more than 25% of its
  total assets in issuers within the same state, industry or economic sector,
  an adverse economic, business or political development may affect the value
  of the Fund's investments more than if its investments were not so concen-
  trated.
..Foreign Risk--The risk that a foreign security (or, in the case of the Tax-
  Exempt California and Tax-Exempt New York Portfolio, a foreign letter of
  credit or guarantee) could lose value as a result of political, financial
  and economic events in foreign countries, less stringent foreign securities
  regulations and accounting and disclosure standards, or other factors. The
  Money Market Portfolio may not invest more than 25% of its total assets in
  the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
Risk that applies to the Money Market Portfolio:
 
..Banking Industry Risk--The risk that if a Fund invests more than 25% of its
  total assets in bank obligations, an adverse development in the banking
  industry may affect the value of the Fund's investments more than if a
  Fund's investments were not invested to such a degree in the banking indus-
  try. Normally, the Money Market Portfolio intends to invest more than 25%
  of its total assets in bank obligations, and the Tax-Exempt California and
  Tax-Exempt New York Portfolio intend to invest at least 65% of their total
  assets in California municipal obligations and New York municipal obliga-
  tions, respectively. Banks may be particularly susceptible to certain eco-
  nomic factors such as interest rate changes, adverse developments in the
  real estate market, fiscal and monetary policy and general economic cycles.
 
Risk that applies to the Tax-Exempt Funds:
 
..Tax Risk--The risk that future legislative or administrative changes or
  court decisions may materially affect the ability of a Fund to pay federal
  tax-exempt dividends (in the case of each of these Funds) and state tax-
  exempt dividends (in the case of the Tax-Exempt California and Tax-Exempt
  New York Funds).
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Service
 Shares from year to year; and (b) how the average annual returns of a Fund's
 Service Shares compare to the returns of a composite of mutual funds with
 similar investment objectives. The bar chart and table assume reinvestment
 of dividends and distributions. A Fund's past performance is not necessarily
 an indication of how the Fund will perform in the future. Performance
 reflects expense limitations in effect. If expense limitations were not in
 place, a Fund's performance would have been reduced. You may obtain a Fund's
 current yield by calling 1-800-621-2550.

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

 ers' accounts. You should contact your service organization for information
 regarding such charges. Such fees may affect the return their customers
 realize with respect to their investments.
 
 Certain Service Organizations may receive other compensation in connection

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

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled.
 
 The Investment Adviser has voluntarily agreed to reduce or otherwise limit
 the daily expenses of each Fund (excluding fees payable under service,
 administration and distribution plans for certain share classes, taxes,
 interest, brokerage and litigation, indemnification and other extraordinary
 expenses) on an annualized basis to 0.43% of the average daily net assets of
 the Fund. Such reductions or limits, if any, are calculated monthly on a
 cumulative basis. These reductions or limits may be discontinued or modified
 only with the express approval of the Trustees.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606, also serves as the Fund's
 transfer agent (the "Transfer Agent") and as such, performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," which may lead to computer shutdowns or
 errors (commonly known as the "Year 2000 Problem"). To the extent these sys-
 tems conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.

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

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

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

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

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

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

 What Is My Minimum Investment In The Funds?
 The Funds do not have any minimum purchase or account requirements with
 respect to Service Shares. A Service Organization may, however, impose a
 minimum amount for initial and subsequent investments in Service Shares, and
 may establish other requirements such as a minimum account balance. A Serv-
 ice Organization may redeem Service Shares held by non-complying accounts,
 and may impose a charge for any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
..Modify or waive the minimum investment and minimum account balance require-
  ment.
..Reject any purchase order for any reason.
 
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Service Shares
 is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
..NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (usu-
  ally 4:00 p.m. New york time). Fund Shares will be priced on any day the
  New York Stock Exchange is open, except for days on which Chicago, Boston
  or New York banks are closed for local holidays.
..On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
..The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.

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

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

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

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

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

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

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

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

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

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

 larly susceptible to certain economic factors, such as interest rate changes
 and adverse developments in the real estate markets. Fiscal and monetary
 policy and general economic cycles can affect the availability and cost of
 funds, loan demand and asset quality and thereby impact the earnings and
 financial conditions of banks.
 
 Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
 asset-backed and receivables-backed securities, whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed and receivables-backed securities are often subject to more
 rapid repayment than their stated maturity date would indicate as a result
 of the pass-through of prepayments of principal on the underlying loans.
 During periods of declining interest rates, prepayment of loans underlying
 asset-backed and receivables-backed securities can be expected to
 accelerate. Accordingly, a Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. In addition, securities that are backed by
 credit card, automobile and similar types of receivables generally do not
 have the benefit of a security interest in collateral that is comparable in
 quality to mortgage assets. There is the possibility that, in some cases,
 recoveries on repossessed collateral may not be available to support
 payments on these securities. In the event of a default, a Fund may suffer a
 loss if it cannot sell collateral quickly and receive the amount it is owed.
 
 Foreign Government Obligations and Related Foreign Risks. Foreign government
 obligations are U.S. dollar-denominated obligations (limited to commercial
 paper and other notes) issued or guaranteed by a foreign government or other
 entity located or organized in a foreign country that maintains a short-term
 foreign currency rating in the highest short-term ratings category by the
 requisite number of NRSROs.
 
 Investments by a Fund in foreign securities, whether issued by a foreign
 government, bank, corporation or other issuer, may present a greater degree
 of risk than investments in securities of domestic issuers because of less
 publicly-available financial and other information, less securities regula-
 tion, potential imposition of foreign withholding and other taxes, war,
 expropriation or other adverse governmental actions. Foreign banks and their
 foreign branches are not regulated by U.S. banking authorities, and gener-
 ally are not bound by the accounting, auditing and financial reporting stan-
 dards applicable to U.S. banks.
 
                                                                            3-FF
<PAGE>
 
 
 
 Repurchase Agreements. Certain Funds may enter into repurchase agreements
 with primary dealers in U.S. Government securities and banks affiliated with
 primary dealers. Repurchase agreements involve the purchase of securities
 subject to the seller's agreement to repurchase them at a mutually agreed
 upon date and price. The repurchase price will exceed the original purchase
 price, the difference being income to the Fund, and will be unrelated to the
 interest rate on the purchased security.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund in connection with the repurchase agree-
 ment are less than the repurchase price and Fund's costs associated with
 delay and enforcement of the repurchase agreement. In addition, in the event
 of bankruptcy of the seller, a Fund could suffer additional losses if a
 court determines that the Fund's interest in the collateral is not enforce-
 able.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.
 
 Municipal Obligations. Municipal obligations are issued by or on behalf of
 states, territories and possessions of the United States and their political
 subdivisions, agencies, authorities and instrumentalities, and the District
 of Columbia. Municipal obligations may include fixed rate notes and similar
 debt instruments; variable and floating rate demand instruments; tax-exempt
 commercial paper; municipal bonds; and unrated notes, paper, bonds or other
 instruments.
 
 Municipal Notes and Bonds. Municipal notes include tax anticipation notes
 ("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
 ("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
 notes. Municipal bonds include general obligation bonds and revenue bonds.
 General obligation bonds are backed by the taxing power of the issuing
 municipality and are considered the safest type of municipal obligation.
 Revenue bonds are backed by the revenues of a project or facility such as
 the tolls from a toll bridge. Revenue bonds also include lease rental reve-
 nue bonds which are issued by a state or local authority for capital pro-
 jects and are secured by annual lease payments from the state or locality
 sufficient to cover debt service on the authority's obliga-

                                                                      APPENDIX A
 
 tions. Industrial development bonds ("private activity bonds") are a spe-
 cific type of revenue bond backed by the credit and security of a private
 user and, therefore, have more potential risk. Municipal bonds may be issued
 in a variety of forms, including commercial paper, tender option bonds and
 variable and floating rate securities.
 
 Tender Option Bonds. A tender option bond is a municipal obligation (gener-
 ally held pursuant to a custodial arrangement) having a relatively long
 maturity and bearing interest at a fixed rate substantially higher than pre-
 vailing short-term, tax-exempt rates. The bond is typically issued in con-
 junction with the agreement of a third party, such as a bank, broker-dealer
 or other financial institution, pursuant to which the institution grants the
 security holder the option, at periodic intervals, to tender its securities
 to the institution. As consideration for providing the option, the financial
 institution receives periodic fees equal to the difference between the
 bond's fixed coupon rate and the rate, as determined by a remarketing or
 similar agent, that would cause the securities, coupled with the tender
 option, to trade at par on the date of such determination. Thus, after pay-
 ment of this fee, the security holder effectively holds a demand obligation
 that bears interest at the prevailing short-term, tax-exempt rate. Certain
 tender option bonds may be illiquid. An institution will normally not be
 obligated to accept tendered bonds in the event of certain defaults or a
 significant downgrading in the credit rating assigned to the issuer of the
 bond. The tender option will be taken into account in determining the matu-
 rity of the tender option bonds and a Fund's average portfolio maturity.
 There is a risk that a Fund will not be considered the owner of a tender
 option bond for federal income tax purposes, and thus will not be entitled
 to treat such interest as exempt from federal income tax.
 
 Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
 issued in anticipation of the issuer's receipt of revenues and present the
 risk that such revenues will be insufficient to satisfy the issuer's payment
 obligations. The entire amount of principal and interest on RAWs is due at
 maturity. RAWs, including those with a maturity of more than 397 days, may
 also be repackaged as instruments which include a demand feature that per-
 mits the holder to sell the RAWs to a bank or other financial institution at
 a purchase price equal to par plus accrued interest on each interest rate
 reset date.
 
 Industrial Development Bonds. Certain Funds may invest in industrial devel-
 opment bonds (private activity bonds), the interest from which would be an
 item of tax preference when distributed by a Fund as "exempt-interest divi-
 dends" to shareholders under the federal alternative minimum tax.
 
 Other Policies. Certain Funds may invest 25% or more of the value of their
 respective total assets in municipal obligations which are related in such a
 way that an
 
                                                                            5-FF
<PAGE>
 
 
 economic, business or political development or change affecting one munici-
 pal obligation would also affect the other municipal obligation. For exam-
 ple, such Funds may invest all of their respective assets in (a) municipal
 obligations the interest of which is paid solely from revenues from similar
 projects such as hospitals, electric utility systems, multi-family housing,
 nursing homes, commercial facilities (including hotels), steel companies or
 life care facilities, (b) municipal obligations whose issuers are in the
 same state, or (c) industrial development obligations. Concentration of a
 Fund's investments in these municipal obligations will subject the Fund, to
 a greater extent than if such investment was not so concentrated, to the
 risks of adverse economic, business or political developments affecting the
 particular state, industry or other area of concentration.
 
 Municipal obligations may be backed by letters of credit or other forms of
 credit enhancement issued by domestic banks or foreign banks which have a
 branch, agency or subsidiary in the United States or by other financial
 institutions. The credit quality of these banks and financial institutions
 could, therefore, cause a loss to a Fund that invests in municipal obliga-
 tions. Letters of credit and other obligations of foreign banks and finan-
 cial institutions may involve risks in addition to those of domestic obliga-
 tions. See "Foreign Government Obligations and Related Foreign Risks" above.
 In addition, the Funds may acquire securities in the form of custodial
 receipts which evidence ownership of future interest payments, principal
 payments or both on obligations of certain state and local governments and
 authorities.
 
 In order to enhance the liquidity, stability or quality of a municipal obli-
 gation, a Fund may acquire the right to sell the obligation to another party
 at a guaranteed price and date.
 
 Miscellaneous Investments and Policies
 
 Floating and Variable Rate Obligations. The Funds may purchase floating and
 variable rate obligations. The value of these obligations is generally more
 stable than that of a fixed rate obligation in response to changes in inter-
 est rate levels. Subject to the conditions for using amortized cost valua-
 tion under the Investment Company Act, a Fund may consider the maturity of a
 variable or floating rate obligation to be shorter than its ultimate stated
 maturity if the obligation is a U.S. Treasury obligation or U.S. Government
 security, if the obligation has a remaining maturity of 397 calendar days or
 less, or if the obligation has a demand feature that permits the Fund to
 receive payment at any time or at specified intervals not exceeding 397 cal-
 endar days. The issuers or financial intermediaries providing demand fea-
 tures may support their ability to purchase the obligations by obtaining
 credit with liquidity supports. These may include lines of credit, which are
 condi-

                                                                      APPENDIX A
 
 tional commitments to lend and letters of credit, which will ordinarily be
 irrevocable, both of which may be issued by domestic banks or foreign banks
 which have a branch, agency or subsidiary in the United States. A Fund may
 purchase variable or floating rate obligations from the issuers or may pur-
 chase certificates of participation, a type of floating or variable rate
 obligation, which are interests in a pool of debt obligations held by a bank
 or other financial institution.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to a Fund at the time of entering into the transac-
 tion. A forward commitment involves entering into a contract to purchase or
 sell securities for a fixed price at a future date beyond the customary set-
 tlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although a Fund would gener-
 ally purchase securities on a when-issued or forward commitment basis with
 the intention of acquiring the securities for its portfolio, a Fund may dis-
 pose of when-issued securities or forward commitments before settlement
 whenever the Investment Adviser deems it appropriate.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Investment Com-
 pany Act. These limitations include a prohibition on any Fund acquiring more
 than 3% of the voting shares of any other investment company, and a prohibi-
 tion on investing more than 5% of a Fund's total assets in securities of any
 one investment company or more than 10% of its total assets in securities of
 all investment companies. A Fund will indirectly bear its proportionate
 share of any management fees and other expenses paid by such other invest-
 ment companies. Such other investment companies will have investment objec-
 tives, policies and restrictions substantially similar to those of the
 acquiring Fund and will be subject to substantially the same risks.
 
 Illiquid Securities. Each Fund may invest up to 10% of its net assets in
 illiquid securities which cannot be disposed of in seven days in the ordi-
 nary course of business at fair value. Illiquid securities include:
 
  . Both domestic and foreign securities that are not readily marketable
  . Certain municipal leases and participation interests
  . Certain stripped mortgage-backed securities
 
                                                                            7-FF
<PAGE>
 
 
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that a
   restricted security is liquid because it is so-called "4(2) commercial
   paper" or is otherwise eligible for resale pursuant to Rule 144A under the
   Securities Act of 1933.
 
 Investing in restricted securities may decrease the liquidity of a Fund's
 portfolio.
 
 Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from
 banks for temporary or emergency purposes. A Fund may not make additional
 investments if borrowings exceed 5% of its net assets. For more information,
 see the Additional Statement.
 
 Downgraded Securities. After its purchase, a portfolio security may be
 assigned a lower rating or cease to be rated. If this occurs, a Fund may
 continue to hold the security if the Investment Adviser believes it is in
 the best interests of the Fund and its shareholders.

Special Risks and Policies Applicable to the Tax-Exempt Funds:
 
Fundamental Policies. As a matter of fundamental policy, at least 80% of each
of the net assets of each of the Tax-Exempt Diversified, Tax-Exempt California
and Tax-Exempt New York Portfolios will ordinarily be invested in municipal
obligations, the interest from which is, in the opinion of bond counsel, if
any, excluded from gross income for federal income tax purposes. In addition,
as a matter of fundamental policy, at least 65% of each of the Tax-Exempt Cali-
fornia and Tax-Exempt New York Portfolio's total assets will be invested in
California and New York municipal obligations, except in extraordinary circum-
stances.
 
For these purposes, California and New York municipal obligations are obliga-
tions issued by or on behalf of the State of California or the State of New
York, respectively, and their respective political subdivisions, agencies and
instrumentalities and the government of Puerto Rico, the U.S. Virgin Islands
and Guam, the interest from which is excluded from gross income for federal
income tax purposes and is exempt from California State personal income tax or
New York State and New York City personal income tax. Each Tax-Exempt Fund may
temporarily invest in taxable money market instruments or, in the case of the
Tax-Exempt California and New York Portfolios, in municipal obligations that
are not California or New York municipal obligations, respectively, when
acceptable California and New York municipal obligations are not available or
when the Investment Adviser believes that the market conditions dictate a
defensive posture. Investments in taxable money market instruments will be lim-
ited to those meeting the quality standards of each Tax-Exempt Fund. The Tax-
Exempt California and Tax-Exempt New York Portfolios' distributions of interest
from municipal obligations other than California and New York municipal obliga-
tions, respectively, may be subject to California and New York State and New
York City personal income taxes.
 
Risks of Investing in California and New York: The Tax-Exempt California and
Tax-Exempt New York Portfolios concentrate their investments in California and
New York municipal obligations. Consequently, these Funds are more susceptible
to factors adversely affecting issuers of California and New York municipal
obligations, and may be riskier than comparable municipal bond funds and money
market funds that do not emphasize these issuers to this degree.
 
The Tax-Exempt California Portfolio's investments can be affected by political
and economic developments within the State of California (the "State"), and by
 
                                                                           1-FFF

the financial condition of the State, its public authorities and political sub-
divisions. After suffering a severe recession in the early 1990's which caused
the State to experience financial difficulties, California's economy entered a
sustained recovery since late 1993 and the State's budget has returned to a
positive balance. California's long-term credit rating has been raised after
being reduced during the recession. To respond to its own revenue shortfalls
during the recession, the State reduced assistance to its public authorities
and political subdivisions. Cutbacks in state aid could further adversely
affect the financial condition of cities, counties and education districts
which are subject to their own fiscal constraints. California voters in the
past have passed amendments to the California Constitution and other measures
that limit the taxing and spending authority of California governmental enti-
ties, and future voter initiatives could result in adverse consequences affect-
ing California municipal obligations. Also, the ultimate fiscal effect of fed-
erally-mandated reform of welfare programs on the State and its local
governments is still to be resolved.
 
These factors, among others (including the outcome of related pending litiga-
tion), could reduce the credit standing of certain issuers of California munic-
ipal obligations. A more detailed discussion of the risks of investing in Cali-
fornia is included in the Additional Statement.
 
The Tax-Exempt New York Portfolio's investments will be affected by political
and economic developments within the State of New York (the "State"), and by
the financial conditions of the State, its public authorities and political
subdivisions, particularly the City of New York (the "City"). The State and the
City face long-term economic problems that could seriously affect their ability
and that of other issuers of New York municipal obligations to meet their
financial obligations. Certain substantial issuers of New York municipal obli-
gations (including issuers whose obligations may be acquired by the Fund) have
experienced serious financial difficulties in recent years. These difficulties
have at times jeopardized the credit standing and impaired the borrowing abili-
ties of all New York issuers and have generally contributed to higher interest
costs for their borrowings and fewer markets for their outstanding debt obliga-
tions. Although several different issues of municipal obligations of the State
and its agencies and instrumentalities and of the City have been downgraded by
S&P and Moody's in recent years, the most recent actions of S&P and Moody's
have been to place the debt obligations of the State on Credit Watch with posi-
tive implications and to upgrade the debt obligations of the City, respective-
ly. Strong demand for New York municipal obligations has also at times had the
effect of permitting New York municipal obligations to be issued with yields
relatively lower, and after issuance, to trade in the market at prices rela-
tively higher, than comparably rated municipal obligations issued by other
jurisdictions. A recurrence of the financial difficulties previously experi-
enced by certain issuers of New York municipal obligations could result in
defaults or declines in the market values of those issuers' existing obliga-
tions and,
 
2-FFF
<PAGE>
 
 
possibly, in the obligations of other issuers of New York municipal obliga-
tions. Although as of April 1, 1999 no issuers were in default with respect to
the payment of their New York municipal obligations, the occurrence of any such
default could materially affect adversely the market values and marketability
of all New York municipal obligations and, consequently, the NAV of the Fund's
holdings. A more detailed discussion of the risks of investing in New York is
included in the Additional Statement.
 
If California, New York, or any of their local governmental entities are unable
to meet their financial obligations, the corresponding Fund's income, NAV,
ability to preserve or realize appreciation of capital or liquidity could be
adversely affected. Also, neither of these Funds is a diversified fund (except
to the extent that diversification is required by Rule 2a-7 or for federal
income tax purposes). Because they may invest a larger percentage of their
assets in the securities of fewer issuers than do diversified funds, these
Funds may be exposed to greater risk in that an adverse change in the condition
of one or a small number of issuers would have a greater impact on them.

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

 General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment adviser to the
 Funds. Goldman Sachs Asset Management is referred to in this Prospectus as
 the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy
 The Money Market Funds are managed to seek maximum current income consistent
 with the preservation of capital and daily liquidity. In managing the Funds,
 the Investment Adviser follows a conservative, risk-controlled investment
 process that seeks to:
..Manage credit risk
..Manage interest rate risk
..Manage liquidity
 
 The Investment Adviser actively manages the Goldman Sachs Money Market Funds
 in designing and structuring the Fund's investment portfolios.
 
- --------------------------------------------------------------------------------
 
 Investment Process
 The Investment Adviser follows a consistent five-step investment process
 across all of its money market portfolios.
 
 1. Define investment objectives and risk parameters
 The Investment Adviser works closely within Fund and Rule 2a-7 guidelines in
 seeking to meet investment objectives for each Fund.
 
 2. Establish benchmarks
 Benchmarks are the IBC Financial Data Universal Averages. Depending upon the
 eligible investments of each Fund, there is a corresponding IBC Index.
 
 3. Establish a risk-managed framework
 Understanding and managing risk is critical to the performance of money mar-
 ket fund portfolios.
 
 4. Actively manage the portfolios
 General portfolio strategy meetings are held weekly.
 
                                                                            1-RR
<PAGE>
 
 
 
 5. Monitor Risk Exposure
 Risk reports enable the Investment Adviser to monitor portfolios on a daily
 basis and track all trading activity.
 
..The Funds: Each Fund's securities are valued by the amortized cost method
  as permitted under Rule 2a-7 of the Investment Company Act of 1940, as
  amended (the "1940 Act"). Under Rule 2a-7, each Fund may invest only in
  U.S. dollar denominated securities that are determined to present minimal
  credit risk and meet certain other criteria including those conditions
  relating to maturity, diversification and credit quality. These operating
  policies may be more restrictive than the fundamental policies set forth in
  the Statement of Additional Information (the "Additional Statement").
  .Taxable Funds: Prime Obligations, Money Market and Government Portfolios
  .Tax-Exempt Funds: Tax-Exempt Diversified, Tax-Exempt California and Tax-
   Exempt New York Portfolios
..The Investors: The Funds are designed for investors seeking a high rate of
  return, a stable net asset value ("NAV") and convenient liquidation privi-
  leges. The Funds are particularly suitable for banks, corporations and
  other financial institutions that seek investment of short-term funds for
  their own accounts or for the accounts of their customers.
..NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
..Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
  mined pursuant to Rule 2a-7) at the time of purchase.
..Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
  (as required by Rule 2a-7).
..Investment Restrictions: Each Fund is subject to certain investment
  restrictions that are described in detail under "Investment Restrictions"
  in the Additional Statement. Fundamental investment restrictions and the
  investment objective of a Fund (except the Tax-Exempt California and Tax-
  Exempt New York Portfolios' objectives of providing shareholders with
  income exempt from California State and New York State and New York City
  personal income tax, respectively) cannot be changed without approval of a
  majority of the outstanding shares of that Fund. All investment policies
  not specifically designated as fundamental are non-fundamental and may be
  changed without shareholder approval.
..Diversification: Diversification can a Fund reduce the risks of investing.
  In accordance with current regulations of the Securities and Exchange Com-
  mission (the "SEC"), each Fund may not invest more than 5% of the value of
  its

  total assets at the time of purchase in the securities of any single issuer
  with these exceptions: (a) the Tax-Exempt California and Tax-Exempt New
  York Portfolios may each invest up to 25% of their total assets in five or
  fewer issuers; and (b) each of the other Funds may invest up to 25% of its
  total assets in the securities of a single issuer for up to three business
  days. These limitations do not apply to cash, certain repurchase agree-
  ments, U.S. Government Securities or securities of other investment compa-
  nies. In addition, securities subject to certain unconditional guarantees
  and securities that are not "First Tier Securities" as defined by the SEC
  are subject to different diversification requirements as described in the
  Additional Statement.
 
                                                                            3-RR

 Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 Taxable Funds:
 
 The Prime Obligations, Money Market and Government Portfolios seek to maxi-
 mize current income to the extent consistent with the preservation of capi-
 tal and the maintenance of liquidity by investing exclusively in high qual-
 ity money market instruments.
 
 Tax-Exempt Funds:
 
 The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
 Portfolios seek to provide shareholders, to the extent consistent with the
 preservation of capital and prescribed portfolio standards, with a high
 level of income exempt from federal income tax by investing primarily in
 municipal instruments.
 
 In addition, the Tax-Exempt California and Tax-Exempt New York Portfolios
 seek to provide shareholders with income exempt from California State and
 New York State and City personal income taxes, respectively.
 
 The Tax-Exempt Funds pursue their investment objectives by limiting their
 investments to securities issued by or on behalf of states, territories, and
 possessions of the United States and their political subdivisions, agencies,
 authorities and instrumentalities, and the District of Columbia, the inter-
 est from which, if any, is in the opinion of bond counsel excluded from
 gross income for federal income tax purposes, and not an item of tax prefer-
 ence under the federal alternative minimum tax.

   defensive purposes, invest less than 25% of its total assets in bank
   obligations.
 /2/To the extent required by Rule 2a-7, asset-backed and receivables-backed
   securities will be rated by the requisite number of nationally recognized

   First Tier Securities, or to the extent that a Fund may purchase Second
   Tier Securities, comparable in quality to Second Tier Securities. In
   addition, a Fund holding a security supported by a guarantee or demand

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

Risks that apply to all Funds:
 
..Money Market Risk--The risk that a Fund will not be able to maintain a NAV
  per share of $1.00 at all times.
..Interest Rate Risk--The risk that during periods of rising interest rates,
  a Fund's yield (and the market value of its securities) will tend to be
  lower than prevailing market rates; in periods of falling interest rates, a
  Fund's yield will tend to be higher.
..Credit/Default Risk--The risk that an issuer or guarantor of a security, or
  a bank or other financial institution that has entered into a repurchase
  agreement, may default on its payment obligations.
..Management Risk--The risk that a strategy used by the Investment Adviser
  may fail to produce the intended results.
 
10-RR
<PAGE>
 
 
..Liquidity Risk--The risk that a Fund will be unable to pay redemption pro-
  ceeds within the time period stated in this Prospectus, because of either
  unusual market conditions, an unusually high volume of redemption requests,
  or other reasons.
..Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by
  the "Year 2000 Problem."
 
Risk that applies to the Government Portfolio:
 
..Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market, Tax-Exempt Diversified, Tax-Exempt
California and Tax-Exempt New York Portfolios:
 
..Concentration Risk--The risk that if a Fund invests more than 25% of its
  total assets in issuers within the same state, industry or economic sector,
  an adverse economic, business or political development may affect the value
  of the Fund's investments more than if its investments were not so concen-
  trated.
..Foreign Risk--The risk that a foreign security (or, in the case of the Tax-
  Exempt California and Tax-Exempt New York Portfolios, a foreign letter of
  credit or guarantee) could lose value as a result of political, financial
  and economic events in foreign countries, less stringent foreign securities
  regulations and accounting and disclosure standards, or other factors. The
  Money Market Portfolio may not invest more than 25% of its total assets in
  the securities of any one foreign government.
 
Risk that applies to the Money Market Portfolio:
 
..Banking Industry Risk--The risk that if a Fund invests more than 25% of its
  total assets in bank obligations, an adverse development in the banking
  industry may affect the value of the Fund's investments more than if a
  Fund's investments were not invested to such a degree in the banking indus-
  try. Normally, the Money Market Portfolio intends to invest more than 25%
  of its total assets in bank obligations, and the Tax-Exempt California and
  Tax-Exempt New York Portfolios intend to invest at least 65% of their total
  assets in California municipal obligations and New York municipal obliga-
  tions, respectively. Banks may be particularly susceptible to certain eco-
  nomic factors such as interest rate changes, adverse developments in the
  real estate market, fiscal and monetary policy and general economic cycles.
 
                                                                           11-RR
<PAGE>
 
 
 
Risk that applies to the Tax-Exempt Funds:
 
 ^Tax Risk--The risk that future legislative or administrative changes or
  court decisions may materially affect the ability of a Fund to pay federal
  tax-exempt dividends (in the case of each of these Funds) and state tax-
  exempt dividends (in the case of the Tax-Exempt California and Tax-Exempt
  New York Portfolios).
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 Cash Management Shares of the Fund have less than one calendar year's per-
 formance. For this reason, the performance information shown below is for
 another Class of Shares (ILA Service Shares) that is not offered in this
 Prospectus but would have substantially similar annual returns because both
 Classes of Shares will be invested in the same portfolio of securities.
 Annual returns will differ only to the extent that the classes do not have
 the same expenses. In reviewing this performance information, however, you
 should be aware that ILA Service Shares have a 0.40% (annualized) service
 fee while Cash Management Shares have 1.00% distribution and service fees.
 If the expenses of the Cash Management Shares were reflected, performance
 would be reduced.
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Service
 Shares from year to year; and (b) how the average annual returns of a Fund's
 Service Shares compare to the returns of a composite of mutual funds with
 similar investment objectives. The bar chart and table assume reinvestment
 of dividends and distributions. A Fund's past performance is not necessarily
 an indication of how the Fund will perform in the future. Performance
 reflects expense limitations in effect. If expense limitations were not in
 place, a Fund's performance would have been reduced. You may obtain a Fund's
 current yield by calling 1-800-621-2550.

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

Service Organizations may charge other fees directly to their customers who are
the beneficial owners of Cash Management Shares in connection with their cus-

regarding such charges. Such fees may affect the return their customers realize
with respect to their investments.
 
Certain Service Organizations may receive other compensation in connection with
the sale and distribution of Cash Management Shares or for services to their
customers' accounts and/or the Funds. For additional information regarding such
compensation, see "Shareholder Guide" in the Prospectus and "Other Information"

Service Providers
 
 INVESTMENT ADVISERS
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. As of April  , 1999,
 GSAM, together with its affiliates, acted as investment adviser or distribu-
 tor for assets in excess of $    billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
..Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
..Administers each Fund's business affairs
..Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)
 
 Pursuant to an SEC order, each Taxable Fund may enter into principal trans-
 actions in certain taxable money market instruments, including repurchase
 agreements, with Goldman Sachs.
 
 MANAGEMENT FEES
 
 
 As compensation for its services and its assumption of certain expenses, the
 Investment Adviser is entitled to the following fees, computed daily and
 payable monthly, at the annual rates listed below:

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled.
 
                                                                            XX-1

 The Investment Adviser has voluntarily agreed to reduce or otherwise limit
 the daily expenses of each Fund (excluding fees payable under service,
 administration and distribution plans for certain share classes, taxes,
 interest, brokerage and litigation, indemnification and other extraordinary
 expenses) on an annualized basis to 0.43% of the average daily net assets of
 the Fund. Such reductions or limits, if any, are calculated monthly on a
 cumulative basis. These reductions or limits may be discontinued or modified
 only with the express approval of the Trustees.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606, also serves as the Fund's
 transfer agent (the "Transfer Agent") and as such, performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," which may lead to computer shutdowns or
 errors (commonly known as the "Year 2000 Problem"). To the extent these sys-
 tems conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 Investment Adviser or other Fund service providers do not adequately address
 this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.

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

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

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

                   (8:00 a.m. to 4:00 p.m. New York time)
 --------------------------------------------------------
</TABLE>
 
 Before or immediately after placing an initial purchase order, a Service
 Organization should complete and send to Goldman Sachs the Account Applica-
 tion. Subsequent purchase orders should be accompanied by information iden-
 tifying the account and the Fund in which Cash Management Shares are to be
 purchased.
 
 Service Organizations may send their payments as follows:
..Wire federal funds to The Northern Trust Company ("Northern") as sub-
  custodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); or
 
                                                                            1-SS
<PAGE>
 
 
..Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; or
..Send a check or Federal Reserve draft payable to Goldman Sachs Funds --
  (Name of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago,
  IL 60606-6372. The Trust will not accept a check drawn on a foreign bank or
  a third-party check.
 
 It is strongly recommended that payment be effected by wiring federal funds
 to Northern.
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.
 
 When Do Shares Begin Earning Dividends?
 Dividends begin to accrue as follows:

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

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

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

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

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

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

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

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

 What Types Of Reports Will I Be Sent Regarding Investments In Cash
 Management Shares?
 Service Organizations will receive annual reports containing audited finan-
 cial statements and semiannual reports. Upon request, Service Organizations
 will also be provided with a printed confirmation for each transaction. Any
 dividends and distributions paid by the Funds are also reflected in regular
 statements issued by Goldman Sachs Funds to Service Organizations. Service
 Organizations are responsible for providing these or other reports to their
 customers who are the beneficial owners of Cash Management Shares in accor-
 dance with the rules that apply to their accounts with the Service Organiza-
 tions.
 
 What Are The Distribution Fees Paid By Cash Management Shares?
 The Trust has adopted a distribution plan (the "Plan") to pay distribution
 fees for the sale and distribution of its shares. Because these fees are
 paid out of the Fund's assets on an ongoing basis, over time, these fees
 will increase the cost of your investment and may cost you more than paying
 other types of sales charges. If the fees received by Goldman Sachs pursuant
 to the Plans exceed its expenses, Goldman Sachs may realize a profit from
 this arrangement. Goldman Sachs pays the distribution fee on a quarterly
 basis.
 
 Under the Plan, Goldman Sachs is entitled to a monthly fee from each Fund
 for distribution services equal, on an annual basis, to 0.50%, of a Fund's
 average daily net assets attributable to Cash Management Shares. Currently,
 Goldman Sachs has voluntarily agreed to limit the amount of such fee to
 0.07% of average daily net assets attributable to Cash Management Shares of
 each Fund. As of the date of this Prospectus, Goldman Sachs has no intention
 of modifying or discontinuing such limitation, but may do so in the future
 at its discretion.
 
 The distribution fees payable are subject to the requirements of Rule 12b-1
 under the 1940 Act, and may be used (among other things) for:
..Compensation paid to and expenses incurred by Service Organizations,
  Goldman Sachs and their respective officers, employees and sales
  representatives;
..Commissions paid to Service Organizations;
..Allocable overhead;
..Telephone and travel expenses;
..Printing of prospectuses for prospective shareholders;
..Preparation and distribution of sales literature or advertising of any
  type; and
..All other expenses incurred in connection with activities primarily
  intended to result in the sale of Cash Management Shares.
 
                                                                            9-SS
<PAGE>
 
Dividends
 
All or substantially all of each Fund's net investment income will be declared
as a dividend daily. Dividends will normally, but not always, be declared as of
4:00 p.m. New York time as a dividend and distributed to Service Organizations
monthly. Service Organizations may choose to have dividends paid in:
 
.. Cash
.. Additional shares of the same class of the same Fund
 
Service Organizations may indicate their election on the Account Application.
Any changes may be submitted in writing to Goldman Sachs at any time. If a
Service Organization does not indicate any choice, dividends and distributions
will be reinvested automatically in the applicable Fund.
 
Dividends will be reinvested as of the last calendar day of each month. Cash
distributions normally will be paid on or about the first business day of each
month. Net short-term capital gains, if any, will be distributed in accordance
with federal income tax requirements and may be reflected in a Fund's daily
distributions.
 
Each Fund may distribute at least annually other realized capital gains, if
any, after reduction by available capital losses. In order to avoid excessive
fluctuations in the amount of monthly capital gains distributions, a portion of
any net capital gains realized on the disposition of securities during the
months of November and December may be distributed during the subsequent calen-
dar year. Although realized gains and losses on the assets of a Fund are
reflected in the NAV of the Fund, they are not expected to be of an amount
which would affect the Fund's NAV of $1.00 per share.
 
The income declared as a dividend for the Government Portfolio is based on
estimates of net investment income for the Fund. Actual income may differ from
estimates, and differences, if any, will be included in the calculation of sub-
sequent dividends.

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

U.S. Government securities have historically involved little risk of loss of
principal if held to maturity. However, no assurance can be given that the U.S.
Government will provide financial support to U.S. Government agencies, authori-
ties, instrumentalities or sponsored enterprises if it is not obligated to do
so by law.
 
Certain Funds may also acquire U.S. Government securities in the form of custo-
dial receipts. Custodial receipts evidence ownership of future interest pay-
ments, principal payments or both on notes or bonds issued by the U.S. Govern-
ment, its agencies, instrumentalities, political subdivisions or authorities.
For certain securities law purposes, custodial receipts are not considered
obligations of the U.S. Government.
 
Bank Obligations. Bank obligations include certificates of deposit, commercial
paper, unsecured bank promissory notes, bankers' acceptances, time deposits and
other debt obligations. Certain Funds may invest in U.S. bank obligations when
a bank has more than $1 billion in total assets at the time of purchase or is a
subsidiary of such a bank, U.S. dollar-denominated obligations issued or
guaranteed by foreign banks that have more than $1 billion in total assets at
the time of purchase, U.S. branches of such foreign banks (Yankee obligations),
foreign branches of such foreign banks and foreign branches of U.S. banks
having more than $1 billion in total assets at the time of purchase. Bank
obligations may be general obligations of the parent bank or may be limited to
the issuing branch by the terms of the specific obligation or by government
regulation.
 
If a Fund invests more than 25% of its total assets in bank obligations
(whether foreign or domestic), it may be especially affected by favorable and
adverse developments in or related to the banking industry. The activities of
U.S. and most foreign banks are subject to comprehensive regulations which, in
the case of U.S. regulations, have undergone substantial changes in the past
decade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of opera-
tions and profitability of domestic and foreign banks. Significant developments
in the U.S. banking industry have included increased competition from other
types of financial institutions, increased acquisition activity and geographic
expansion. Banks may be particularly susceptible to certain economic factors,
such as interest rate changes and adverse developments in the real estate mar-
kets. Fiscal and monetary policy and general economic cycles can affect the
availability and cost of funds, loan demand and asset quality and thereby
impact the earnings and financial conditions of banks.
 
Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
asset-backed and receivables-backed securities, whose principal and interest
payments are collateralized by pools of assets such as auto loans, credit card
receivables, leases, installment contracts and personal property. Asset-backed
and receivables-backed securities are often subject to more rapid repayment
than their stated maturity date
 
2-YY
<PAGE>
 
                                                                      APPENDIX A
 
would indicate as a result of the pass-through of prepayments of principal on
the underlying loans. During periods of declining interest rates, prepayment of
loans underlying asset-backed and receivables-backed securities can be expected
to accelerate. Accordingly, a Fund's ability to maintain positions in such
securities will be affected by reductions in the principal amount of such secu-
rities resulting from prepayments, and its ability to reinvest the returns of
principal at comparable yields is subject to generally prevailing interest
rates at that time. In addition, securities that are backed by credit card,
automobile and similar types of receivables generally do not have the benefit
of a security interest in collateral that is comparable in quality to mortgage
assets. There is the possibility that, in some cases, recoveries on repossessed
collateral may not be available to support payments on these securities. In the
event of a default, a Fund may suffer a loss if it cannot sell collateral
quickly and receive the amount it is owed.
 
Foreign Government Obligations and Related Foreign Risks
 
Foreign government obligations are U.S. dollar-denominated obligations (limited
to commercial paper and other notes) issued or guaranteed by a foreign govern-
ment or other entity located or organized in a foreign country that maintains a
short-term foreign currency rating in the highest short-term ratings category
by the requisite number of NRSROs.
 
Investments by a Fund in foreign securities, whether issued by a foreign gov-
ernment, bank, corporation or other issuer, may present a greater degree of
risk than investments in securities of domestic issuers because of less public-
ly-available financial and other information, less securities regulation,
potential imposition of foreign withholding and other taxes, war, expropriation
or other adverse governmental actions. Foreign banks and their foreign branches
are not regulated by U.S. banking authorities, and generally are not bound by
the accounting, auditing and financial reporting standards applicable to U.S.
banks.
 
Repurchase Agreements. Each Fund may enter into repurchase agreements with
primary dealers in U.S. Government securities and banks affiliated with primary
dealers. Repurchase agreements involve the purchase of securities subject to
the seller's agreement to repurchase them at a mutually agreed upon date and
price. The repurchase price will exceed the original purchase price, the
difference being income to the Fund, and will be unrelated to the interest rate
on the purchased security.
 
If the other party or "seller" defaults, a Fund might suffer a loss to the
extent that the proceeds from the sale of the underlying securities and other
collateral held by the Fund in connection with the repurchase agreement are
less than the repurchase price and Fund's costs associated with delay and
enforcement of the repurchase
 
                                                                            3-YY
<PAGE>
 
 
agreement. In addition, in the event of bankruptcy of the seller, a Fund could
suffer additional losses if a court determines that the Fund's interest in the
collateral is unenforceable.
 
In evaluating whether to enter into a repurchase agreement, the Investment
Adviser will carefully consider the creditworthiness of the seller. Distribu-
tions of the income from repurchase agreements will be taxable to a Fund's
shareholders. In addition, each Fund, together with other registered investment
companies having advisory agreements with the Investment Adviser or any of its
affiliates, may transfer uninvested cash balances into a single joint account,
the daily aggregate balance of which will be invested in one or more repurchase
agreements.
 
Municipal Obligations. Municipal obligations are issued by or on behalf of
states, territories and possessions of the United States and their political
subdivisions, agencies, authorities and instrumentalities, and the District of
Columbia. Municipal obligations may include fixed rate notes and similar debt
instruments; variable and floating rate demand instruments; tax-exempt commer-
cial paper; municipal bonds; and unrated notes, paper, bonds or other instru-
ments.
 
 
Municipal Notes and Bonds. Municipal notes include tax anticipation notes
("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
notes. Municipal bonds include general obligation bonds and revenue bonds. Gen-
eral obligation bonds are backed by the taxing power of the issuing municipal-
ity and are considered the safest type of municipal obligation. Revenue bonds
are backed by the revenues of a project or facility such as the tolls from a
toll bridge. Revenue bonds also include lease rental revenue bonds which are
issued by a state or local authority for capital projects and are secured by
annual lease payments from the state or locality sufficient to cover debt serv-
ice on the authority's obligations. Industrial development bonds ("private
activity bonds") are a specific type of revenue bond backed by the credit and
security of a private user and, therefore, have more potential risk. Municipal
bonds may be issued in a variety of forms, including commercial paper, tender
option bonds and variable and floating rate securities.
 
Tender Option Bonds. A tender option bond is a municipal obligation (generally
held pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-
term, tax-exempt rates. The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which the institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution. As
consideration for providing the option, the financial institution receives
periodic fees equal to the difference between the bond's fixed coupon rate
 
4-YY
<PAGE>
 
                                                                      APPENDIX A
 
and the rate, as determined by a remarketing or similar agent, that would cause
the securities, coupled with the tender option, to trade at par on the date of
such determination. Thus, after payment of this fee, the security holder effec-
tively holds a demand obligation that bears interest at the prevailing short-
term, tax-exempt rate. Certain tender option bonds may be illiquid. An institu-
tion will normally not be obligated to accept tendered bonds in the event of
certain defaults or a significant downgrading in the credit rating assigned to
the issuer of the bond. The tender option will be taken into account in deter-
mining the maturity of the tender option bonds and a Fund's average portfolio
maturity. There is a risk that a Fund will not be considered the owner of a
tender option bond for federal income tax purposes, and thus will not be enti-
tled to treat such interest as exempt from federal income tax.
 
Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
issued in anticipation of the issuer's receipt of revenues and present the risk
that such revenues will be insufficient to satisfy the issuer's payment obliga-
tions. The entire amount of principal and interest on RAWs is due at maturity.
RAWs, including those with a maturity of more than 397 days, may also be
repackaged as instruments which include a demand feature that permits the
holder to sell the RAWs to a bank or other financial institution at a purchase
price equal to par plus accrued interest on each interest rate reset date.
 
Industrial Development Bonds. Certain Funds may invest in industrial develop-
ment bonds (private activity bonds), the interest from which would be an item
of tax preference when distributed by a Fund as "exempt-interest dividends" to
shareholders under the federal alternative minimum tax.
 
Other Policies. Certain Funds may invest 25% or more of the value of their
respective total assets in municipal obligations which are related in such a
way that an economic, business or political development or change affecting one
municipal obligation would also affect the other municipal obligation. For
example, such Funds may invest all of their respective assets in (a) municipal
obligations the interest of which is paid solely from revenues from similar
projects such as hospitals, electric utility systems, multi-family housing,
nursing homes, commercial facilities (including hotels), steel companies or
life care facilities, (b) municipal obligations whose issuers are in the same
state, or (c) industrial development obligations. Concentration of a Fund's
investments in these municipal obligations will subject the Fund, to a greater
extent than if such investment was not so concentrated, to the risks of adverse
economic, business or political development affecting the particular state,
industry or other area of concentration.
 
Municipal obligations may be backed by letters of credit or other forms of
credit enhancement issued by domestic banks or foreign banks which have a
branch, agency or subsidiary in the United States or by other financial insti-
tutions. The credit quality
 
                                                                            5-YY
<PAGE>
 
 
of these banks and financial institutions could, therefore, cause a loss to a
Fund that invests in municipal obligations. Letters of credit and other obliga-
tions of foreign banks and financial institutions may involve risks in addition
to those of domestic obligations. See "Foreign Government Obligations and
Related Foreign Risks" above. In addition, the Funds may acquire securities in
the form of custodial receipts which evidence ownership of future interest pay-
ments, principal payments or both on obligations of certain state and local
governments and authorities.
 
In order to enhance the liquidity, stability or quality of a municipal obliga-
tion, a Fund may acquire the right to sell the obligation to another party at a
guaranteed price and date.
 
Miscellaneous Investments and Policies
 
Floating and Variable Rate Obligations. The Funds may purchase floating and
variable rate obligations. The value of these obligations is generally more
stable than that of a fixed rate obligation in response to changes in interest
rate levels. Subject to the conditions for using amortized cost valuation under
the Investment Company Act, a Fund may consider the maturity of a variable or
floating rate obligation to be shorter than its ultimate stated maturity if the
obligation is a U.S. Treasury obligation or U.S. Government security, if the
obligation has a remaining maturity of 397 calendar days or less, or if the
obligation has a demand feature that permits the Fund to receive payment at any
time or at specified intervals not exceeding 397 calendar days. The issuers or
financial intermediaries providing demand features may support their ability to
purchase the obligations by obtaining credit with liquidity supports. These may
include lines of credit, which are conditional commitments to lend and letters
of credit, which will ordinarily be irrevocable, both of which may be issued by
domestic banks or foreign banks which have a branch, agency or subsidiary in
the United States. A Fund may purchase variable or floating rate obligations
from the issuers or may purchase certificates of participation, a type of
floating or variable rate obligation, which are interests in a pool of debt
obligations held by a bank or other financial institution.
 
When-Issued Securities and Forward Commitments. When-issued securities are
securities that have been authorized, but not yet issued. When-issued securi-
ties are purchased in order to secure what is considered to be an advantageous
price and yield to a Fund at the time of entering into the transaction. A for-
ward commitment involves entering into a contract to purchase or sell securi-
ties for a fixed price at a future date beyond the customary settlement period.
 
The purchase of securities on a when-issued or forward commitment basis
involves a risk of loss if the value of the security to be purchased declines
before the settlement date. Conversely, the sale of securities on a forward
commitment basis involves the
 
6-YY
<PAGE>
 
                                                                      APPENDIX A
 
risk that the value of the sold securities may increase before the settlement
date. Although a Fund would generally purchase securities on a when-issued or
forward commitment basis with the intention of acquiring the securities for its
portfolio, a Fund may dispose of when-issued securities or forward commitments
before settlement whenever the Investment Adviser deems it appropriate.
 
Other Investment Companies. A Fund may invest in securities of other investment
companies subject to the limitations prescribed by the Investment Company Act.
These limitations include a prohibition on any Fund acquiring more than 3% of
the voting shares of any other investment company, and a prohibition on invest-
ing more than 5% of a Fund's total assets in securities of any one investment
company or more than 10% of its total assets in securities of all investment
companies. Each Fund will indirectly bear its proportionate share of any man-
agement fees and other expenses paid by such other investment companies. Such
other investment companies will have investment objectives, policies and
restrictions substantially similar to those of the acquiring Fund and will be
subject to substantially the same risks.
 
Other Illiquid Securities. Each Fund may invest up to 10% of its net assets in
illiquid securities which cannot be disposed of in seven days in the ordinary
course of business at fair value. Illiquid securities include:
..Both domestic and foreign securities that are not readily marketable
..Certain municipal leases and participation interests
..Certain stripped mortgage-backed securities
..Repurchase agreements and time deposits with a notice or demand period of more
 than seven days
..Certain restricted securities, unless it is determined, based upon a review of
 the trading markets for a specific restricted security, that a restricted
 security is liquid because it is so-called "4(2) commercial paper" or is oth-
 erwise eligible for resale pursuant to Rule 144A under the Securities Act of
 1933.
 
Investing in restricted securities may decrease the liquidity of a Fund's port-
folio.
 
Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from banks
for temporary or emergency purposes. A Fund may not make additional investments
if borrowings exceed 5% of its net assets. For more information, see the Addi-
tional Statement.
 
Downgraded Securities. After its purchase, a portfolio security may be assigned
a lower rating or cease to be rated. If this occurs, a Fund may continue to
hold the security if the Investment Adviser believes it is in the best interest
of the Fund and its shareholders.
 
                                                                            7-YY

Special Risks and Policies Applicable to the Tax-Exempt Funds:
 
Fundamental Policies. As a matter of fundamental policy, at least 80% of each
of the net assets of each of the Tax-Exempt Diversified, Tax-Exempt California
and Tax-Exempt New York Portfolios will ordinarily be invested in municipal
obligations, the interest from which is, in the opinion of bond counsel, if
any, excluded from gross income for federal income tax purposes. In addition,
as a matter of fundamental policy, at least 65% of each of the Tax-Exempt Cali-
fornia and Tax-Exempt New York Portfolio's total assets will be invested in
California and New York municipal obligations, except in extraordinary circum-
stances.
 
For these purposes, California and New York municipal obligations are obliga-
tions issued by or on behalf of the State of California or the State of New
York, respectively, and their respective political subdivisions, agencies and
instrumentalities and the government of Puerto Rico, the U.S. Virgin Islands
and Guam, the interest from which is excluded from gross income for federal
income tax purposes and is exempt from California State personal income tax or
New York State and New York City personal income tax. Each Tax-Exempt Fund may
temporarily invest in taxable money market instruments or, in the case of the
Tax-Exempt California and New York Portfolios, in municipal obligations that
are not California or New York municipal obligations, respectively, when
acceptable California and New York municipal obligations are not available or
when the Investment Adviser believes that the market conditions dictate a
defensive posture. Investments in taxable money market instruments will be lim-
ited to those meeting the quality standards of each Tax-Exempt Fund. The Tax-
Exempt California and Tax-Exempt New York Portfolios' distributions of interest
from municipal obligations other than California and New York municipal obliga-
tions, respectively, may be subject to California and New York State and New
York City personal income taxes.
 
Risks of Investing in California and New York: The Tax-Exempt California and
Tax-Exempt New York Portfolios concentrate their investments in California and
New York municipal obligations. Consequently, these Funds are more susceptible
to factors adversely affecting issuers of California and New York municipal
obligations, and may be riskier than comparable municipal bond funds and money
market funds that do not emphasize these issuers to this degree.
 
The Tax-Exempt California Portfolio's investments can be affected by political
and economic developments within the State of California (the "State"), and by
the financial condition of the State, its public authorities and political sub-
divisions. After suffering a severe recession in the early 1990's which caused
the State to experience financial difficulties, California's economy entered a
sustained recovery since late 1993 and the State's budget has returned to a
positive balance. California's long-term
 
8-YY
<PAGE>
 
                                                                      APPENDIX A
 
credit rating has been raised after being reduced during the recession. To
respond to its own revenue shortfalls during the recession, the State reduced
assistance to its public authorities and political subdivisions. Cutbacks in
state aid could further adversely affect the financial condition of cities,
counties and education districts which are subject to their own fiscal
constraints. California voters in the past have passed amendments to the Cali-
fornia Constitution and other measures that limit the taxing and spending
authority of California governmental entities, and future voter initiatives
could result in adverse consequences affecting California municipal obliga-
tions. Also, the ultimate fiscal effect of federally-mandated reform of welfare
programs on the State and its local governments is still to be resolved.
 
These factors, among others (including the outcome of related pending litiga-
tion), could reduce the credit standing of certain issuers of California munic-
ipal obligations. A more detailed discussion of the risks of investing in Cali-
fornia is included in the Additional Statement.
 
The Tax-Exempt New York Portfolio's investments will be affected by political
and economic developments within the State of New York (the "State"), and by
the financial conditions of the State, its public authorities and political
subdivisions, particularly the City of New York (the "City"). The State and the
City face long-term economic problems that could seriously affect their ability
and that of other issuers of New York municipal obligations to meet their
financial obligations. Certain substantial issuers of New York municipal obli-
gations (including issuers whose obligations may be acquired by the Fund) have
experienced serious financial difficulties in recent years. These difficulties
have at times jeopardized the credit standing and impaired the borrowing abili-
ties of all New York issuers and have generally contributed to higher interest
costs for their borrowings and fewer markets for their outstanding debt obliga-
tions. Although several different issues of municipal obligations of the State
and its agencies and instrumentalities and of the City have been downgraded by
S&P and Moody's in recent years, the most recent actions of S&P and Moody's
have been to place the debt obligations of the State on Credit Watch with posi-
tive implications and to upgrade the debt obligations of the City, respective-
ly. Strong demand for New York municipal obligations has also at times had the
effect of permitting New York municipal obligations to be issued with yields
relatively lower, and after issuance, to trade in the market at prices rela-
tively higher, than comparably rated municipal obligations issued by other
jurisdictions. A recurrence of the financial difficulties previously experi-
enced by certain issuers of New York municipal obligations could result in
defaults or declines in the market values of those issuers' existing obliga-
tions and, possibly, in the obligations of other issuers of New York municipal
obligations. Although as of April 1, 1999 no issuers were in default with
respect to the payment of their New York municipal obligations, the occurrence
of any such default could materially affect adversely the market values and
marketability of all New York
 
                                                                            9-YY

municipal obligations and, consequently, the NAV of the Fund's holdings. A more
detailed discussion of the risks of investing in New York is included in the
Additional Statement.
 
If California, New York, or any of their local governmental entities are unable
to meet their financial obligations, the corresponding Fund's income, NAV,
ability to preserve or realize appreciation of capital or liquidity could be
adversely affected. Also, neither of these Funds is a diversified fund (except
to the extent that diversification is required by Rule 2a-7 or for federal
income tax purposes). Because they may invest a larger percentage of their
assets in the securities of fewer issuers than do diversified funds, these
Funds may be exposed to greater risk in that an adverse change in the condition
of one or a small number of issuers would have a greater impact on them.

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

 General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as investment adviser to the
 Funds. Goldman Sachs Asset Management is referred to in this Prospectus as
 the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy
 The Money Market Funds are managed to seek maximum current income consistent
 with the preservation of capital and daily liquidity. In managing the Funds,
 the Investment Adviser follows a conservative, risk-managed investment proc-
 ess that seeks to:
..Manage credit risk
..Manage interest rate risk
..Manage liquidity
 
 The Investment Adviser actively manages the Goldman Sachs Money Market Funds
 in designing and structuring the Fund's investment portfolios.
 
- --------------------------------------------------------------------------------
 
 Investment Process
 The Investment Adviser follows a consistent five-step investment process
 across all of its money market portfolios.
 
 1. Define investment objectives and risk parameters
 The Investment Adviser works closely within Fund and Rule 2a-7 guidelines in
 seeking to meet investment objectives for each Fund.
 
 2. Establish benchmarks
 Benchmarks are the IBC Financial Data Universal Averages. Depending upon the
 eligible investments of each Fund, there is a corresponding IBC Index.
 
 3. Establish a risk-managed framework
 Understanding and managing risk is critical to the performance of money mar-
 ket fund portfolios.
 
 4. Actively manage the portfolios
 General portfolio strategy meetings are held weekly.
 
                                                                            1-TT
<PAGE>
 
 
 
 5. Monitor Risk Exposure
 Risk reports enable the Investment Adviser to monitor portfolios on a daily
 basis and track all trading activity.
 
..The Funds: Each Fund's securities are valued by the amortized cost method as
 permitted under Rule 2a-7 of the Investment Company Act of 1940, as amended
 (the "1940 Act"). Under Rule 2a-7, each Fund may invest only in U.S. dollar
 denominated securities that are determined to present minimal credit risk and
 meet certain other criteria, including those conditions relating to maturity,
 diversification and credit quality. These operating policies may be more
 restrictive than the fundamental policies set forth in the Statement of Addi-
 tional Information (the "Additional Statement").
..Taxable Fund: Prime Obligations Portfolio
..Tax-Exempt Fund: Tax-Exempt Diversified Portfolio
..The Investors: The Funds are designed for investors seeking a high rate of
 return, a stable net asset value ("NAV") and convenient liquidation privi-
 leges.
..NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
..Maximum Remaining Maturity of Portfolio Investments: 13 months (as determined
 pursuant to Rule 2a-7) at the time of purchase.
..Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days (as
 required by Rule 2a-7).
..Investment Restrictions: Each Fund is subject to certain investment restric-
 tions that are described in detail under "Investment Restrictions" in the
 Additional Statement. Fundamental investment restrictions and the investment
 objective of a Fund cannot be changed without approval of a majority of the
 outstanding shares of that Fund. All investment policies not specifically des-
 ignated as fundamental are non-fundamental and may be changed without share-
 holder approval.
..Diversification: Diversification can help a Fund reduce the risks of invest-
 ing. In accordance with current regulations of the Securities and Exchange
 Commission (the "SEC"), each Fund may not invest more than 5% of the value of
 its total assets at the time of purchase in the securities of any single
 issuer except that each Fund may invest up to 25% of its total assets in the
 securities of a single issuer for up to three business days. These limitations
 do not apply to cash, certain repurchase agreements, U.S. Government Securi-
 ties or securities of other investment companies. In addition, securities sub-
 ject to certain unconditional guarantees and securities that are not "First
 Tier Securities" as defined by the SEC are subject to different diversifica-
 tion requirements as described in the Additional Statement.

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

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

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

Risks that apply to all Funds:
 
..Money Market Risk--The risk that a Fund will not be able to maintain a NAV
  per share of $1.00 at all times.
..Interest Rate Risk--The risk that during periods of rising interest rates,
  a Fund's yield (and the market value of its securities) will tend to be
  lower than prevailing market rates; in periods of falling interest rates, a
  Fund's yield will tend to be higher.
..Credit/Default Risk--The risk that an issuer or guarantor of a security, or
  a bank or other financial institution that has entered into a repurchase
  agreement, may default on its payment obligations.
..Management Risk--The risk that a strategy used by the Investment Adviser
  may fail to produce the intended results.

                                                   PRINCIPAL RISKS OF THE FUNDS
 
..Liquidity Risk--The risk that a Fund will be unable to pay redemption pro-
  ceeds within the time period stated in this Prospectus, because of either
  unusual market conditions, an unusually high volume of redemption requests,
  or other reasons.
..Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by
  the "Year 2000 Problem."
 
Risks that apply to the Tax-Exempt Diversified Portfolio:
 
..Concentration Risk--The risk that if a Fund invests more than 25% of its
  total assets in issuers within the same state, industry or economic sector,
  an adverse economic, business or political development may affect the value
  of the Fund's investments more than if its investments were not so concen-
  trated.
..Foreign Risk--The risk that a Fund could suffer a loss from investments in
  municipal instruments which are backed by letters of credit or other forms
  of credit enhancement issued by a foreign bank. Letters of credit and other
  obligations of foreign banks may involve risks in addition to those of
  domestic obligations because of less publicly available financial and other
  information, less securities regulation, less stringent foreign securities
  regulations and accounting and disclosure standards, or other factors.
..Tax Risk--The risk that future legislative or administrative changes or
  court decisions may materially affect the ability of a Fund to pay federal
  tax-exempt dividends.
 
More information about the Fund's portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

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

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

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

Service Organizations may charge other fees directly to their customers who are
the beneficial owners of Service Shares in connection with their customers'
accounts. You should contact your Service Organization for information regard-
ing such charge. Such fees may affect the return such customers realize with
respect to their investments.
 
Certain institutions may receive other compensation in connection with the sale

 Service Providers
 
 INVESTMENT ADVISERS
 
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as Investment Adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. As of April  , 1999,
 GSAM, together with its affiliates, acted as investment adviser or distribu-
 tor for assets in excess of $    billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
..Continually manages each Fund, including the purchase, retention and
  disposition of securities and other assets
..Administers each Fund's business affairs
..Performs various recordholder servicing functions (to the extent not
  provided by other organizations)
 
 Pursuant to an SEC order, the Prime Obligations Portfolio may enter into
 principal transactions in certain taxable money market instruments, includ-
 ing repurchase agreements, with Goldman Sachs.
 
 MANAGEMENT FEES
 
 
 As compensation for its services and its assumption of certain expenses, the
 Investment Adviser, is entitled to the following fees, computed daily and
 payable monthly, at the annual rates listed below:
 
<TABLE>

 -------------------------------------------------------------------
  Tax-Exempt Diversified       0.35%                 0.29%
 -------------------------------------------------------------------
</TABLE>
 
 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled.
 
 The Investment Adviser has voluntarily agreed to reduce or otherwise limit
 the daily expenses of each Fund (excluding fees payable under service,
 administration and distribution plans for certain share classes, taxes,
 interest, brokerage
 
                                                                            1-UU

 and litigation, indemnification and other extraordinary expenses) on an
 annualized basis to 0.43% of the average daily net assets of the Fund. Such
 reductions or limits, if any, are calculated monthly on a cumulative basis.
 These reductions or limits may be discontinued or modified only with the
 express approval of the Trustees.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606, also serves as the Fund's
 transfer agent ( the "Transfer Agent") and as such, performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," which may lead to computer shutdowns or
 errors (commonly known as the "Year 2000 Problem"). To the extent these sys-
 tems conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 computer systems used by the Investment Adviser or other Fund service prov-
 iders do not adequately address this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
..The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problem and the Investment Adviser will continue to
  monitor the situation.

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

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

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

  - Federal funds wires, Automated Clearing House Network ("ACH") transfers
    or bank wires should be sent to the Trust c/o The Northern Trust Company
    ("Northern") as subcustodian for State Street
  - It is expected that Federal Reserve drafts will ordinarily be converted
    to federal funds on the day of receipt and that checks will be converted
    to federal funds within two business days after receipt. ACH transfers
    are expected to convert to federal funds on the business day following
    receipt of the ACH transfer.

 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
..Refuse to open an account if you fail to (i) provide a social security num-
  ber or other taxpayer identification number; or (ii) certify that such num-
  ber is correct (if required to do so under applicable law).
..Reject any purchase order for any reason.
..Modify or waive the minimum investment amounts.
..Modify the manner in which shares are offered.
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Investment Adviser.
 
                                                                            3-VV
<PAGE>
 
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange shares is deter-
 mined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 (Value of Assets of the Class)
                  - (Liabilities of the Class)
     NAV = _______________________________
                 Number of Outstanding Shares of the Class
 
..NAV per share of each class is calculated by State Street on each business
  day as of the close of regular trading on the New York Stock Exchange (usu-
  ally 4:00 p.m. New York time). Fund shares will be priced on any day the
  New York Stock Exchange is open, except for days on which Chicago, Boston,
  or New York banks are closed for local holidays.
..On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be granted to
  the next business day.
..The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 A COMMON QUESTION REGARDING THE PURCHASE OF SERVICE SHARES
 
 
 What Is The Offering Price Of Service Shares?
 You may purchase Service Shares of the Funds at the next determined NAV
 without an initial sales charge. Service Shares are not subject to any ini-
 tial or contingent deferred sales charge or fee for distribution services.
 
 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS B SHARES
 
 
 What Is The Offering Price Of Class B Shares?
 You may purchase Class B Shares of the Funds at the next determined NAV
 without an initial sales charge. However, Class B Shares redeemed within six
 years of purchase will be subject to a CDSC at the rates shown in the table
 below based on how long you held your shares.

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

 A COMMON QUESTION ABOUT THE PURCHASE OF CLASS C SHARES
 
 
 What Is The Offering Price Of Class C Shares?
 You may purchase Class C Shares of the Funds at the next determined NAV
 without paying an initial sales charge. However, if you redeem Class C
 Shares within 12 months of purchase, a CDSC of 1% will be deducted from the
 redemption proceeds.
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class C Shares, including the payment of compensation to Authorized Dealers.
 An amount equal to 1% of the amount invested is paid by the Distributor to
 Authorized Dealers.
 
 COMMON QUESTIONS APPLICABLE TO THE PURCHASE OF SERVICE, CLASS B AND CLASS C
 SHARES
 
 
 What Else Do I Need To Know About The CDSC On Class B Or C Shares?
..No CDSC is charged on shares acquired from reinvested dividends or capital
  gains distributions.
  .When counting the number of months since a purchase of Class B or Class C
   Shares was made, all payments made during a month will be combined and
   considered to have been made on the first day of that month.8
..To keep your CDSC as low as possible, each time you place a request to sell
  shares, the Funds will first sell any shares in your account that do not
  carry a CDSC and then the shares in your account that have been held the
  longest.
 
 In What Situations May The CDSC On Service, Class B Or C Shares Be Waived Or
 Reduced?
 The CDSC on Service, Class B or Class C Shares that are subject to a CDSC
 (i.e., because the Service Shares were acquired in an exchange transaction
 for shares of a Goldman Sachs Fund that were subject to a CDSC) may be
 waived or reduced if the redemption relates to:
..Retirement distributions or loans to participants or beneficiaries from
  pension and profit sharing plans, pension funds and other company-sponsored
  benefit plans (each a "Retirement Plan");
..The death or disability (as defined in Section 72(m)(7) of the Internal
  Revenue Code of 1986, as amended (the "Code")) of a participant or benefi-
  ciary in a Retirement Plan;
..Hardship withdrawals by a participant or beneficiary in a Retirement Plan;
..Satisfying the minimum distribution requirements of the Code;

                                                               SHAREHOLDER GUIDE
 
..Establishing "substantially equal periodic payments" as described under
  Section 72(t)(2) of the Code;
..The separation from service by a participant or beneficiary in a Retirement
  Plan;
..The death or disability (as defined in Section 72(m)(7) of the Code) of a
  shareholder if the redemption is made within one year of the event;
..Excess contributions distributed from a Retirement Plan;
..Distributions from a qualified Retirement Plan invested in the Goldman
  Sachs Funds which are being rolled over to a Goldman Sachs IRA; or
..Redemption proceeds which are to be reinvested in accounts or non-regis-
  tered products over which GSAM or its advisory affiliates have investment
  discretion.
 
 In addition, Service, Class B and Class C Shares subject to a systematic
 withdrawal plan may be redeemed without a CDSC. The Funds reserve the right
 to limit such redemptions, on an annual basis to 10% of the value of your
 Service Shares and 12% each of the value of your Class B and C Shares.
 
 What Other Attributes of Service, Class B Or Class C Shares Should I Know
 About?
..Service Shares. Service Shares are normally not subject to any initial
  sales charge or CDSC. However, Service Shares are subject to a service fee
  at the annual rate of 0.40% of a Fund's average daily net assets attribut-
  able to Service Shares.
..Class B Shares. Class B Shares are subject to a CDSC but not an initial
  sales charge. By not paying a front-end sales charge on non-money market
  fund share purchases, your entire investment in Class B Shares is available
  to work for you from the time you make your initial investment. However,
  the distribution fee of up to 0.75% and service fee of up to 0.25% paid by
  Class B Shares will cause your Class B Shares (until conversion to Service
  Shares) to have a higher expense ratio, and thus lower performance and div-
  idend payments, than Service Shares.
  A maximum purchase limitation of $250,000 in the aggregate normally
  applies to Class B Shares.
..Class C Shares. Class C Shares are also subject to a CDSC but not an ini-
  tial sales charge. By not paying a front-end sales charge on non-money mar-
  ket fund share purchases, your entire investment in Class C Shares is
  available to work for you from the time you make your initial investment.
  However, the distribution fee of 0.75% and service fee of 0.25% paid by
  Class C Shares will cause your Class C Shares to have a higher expense
  ratio, and thus lower performance and dividend payments, than Service
  Shares (or Class B Shares after conversion to Service Shares).
 
                                                                            7-VV
<PAGE>
 
 
  Although Class C Shares are subject to a CDSC for only 12 months, Class C
  Shares do not have the conversion feature applicable to Class B Shares and
  your investment will, therefore, pay higher distribution fees indefinite-
  ly.
  A maximum purchase limitation of $1,000,000 in the aggregate normally
  applies to purchases of Class C Shares.
 
 Note: Authorized Dealers may receive different compensation for selling
 Service, Class B or Class C Shares.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Generally, each Fund will redeem its shares on
 any business day at their NAV next determined after receipt of such request
 in proper form, subject to any applicable CDSC. You may request that redemp-
 tion proceeds be sent to you by check or by wire (if the wire instructions
 are on record).
 
 If your shares are held in a "street name" or omnibus account, you should
 contact your Authorized Dealer to make a redemption. Otherwise, redemptions
 may be requested in writing or by telephone.

 You may also take advantage of the check redemption privilege described
 below.
 
 When Do I Need A Signature Guarantee To Redeem Shares?
 A signature guarantee is required if:
..You are requesting in writing to redeem shares in an amount over $50,000;
..You would like the redemption proceeds sent to an address that is not your
  address of record; or
..You would like to change the bank designated on your Account Application.
 
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federal savings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.
 Additional documentation may be required for executors, trustees or corpora-
 tions or when deemed appropriate by the Transfer Agent.
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 The Trust may accept telephone redemption requests from any person identify-
 ing himself or herself as the owner of an account or the owner's registered
 representative where the owner has not declined in writing to use this serv-
 ice. Thus, you risk possible losses if a telephone redemption is not autho-
 rized by you.
 
 In an effort to prevent unauthorized or fraudulent redemption and exchange
 requests by telephone, Goldman Sachs employs reasonable procedures specified
 by the Trust to confirm that such instructions are genuine. If reasonable
 procedures are not employed, the Trust may be liable for any loss due to
 unauthorized or fraudulent transactions. The following general policies are
 currently in effect:
..All telephone requests are recorded.
..Proceeds of telephone redemption requests will be sent only to your address
  of record or authorized bank account designated on your Account Application
  (unless you provide written instructions and a signature guarantee, indi-
  cating another address or account) and exchanges of shares normally will be
  made only to an identically registered account.
..Telephone redemptions will not be accepted during the 30-day period follow-
  ing any change in your address of record.
..The telephone redemption option does not apply to shares held in a "street
  name" account. "Street name" accounts are accounts maintained and serviced
 
                                                                            9-VV
<PAGE>
 
 
  by your Authorized Dealer. If your account is held in "street name," you
  should contact your registered representative of record, who may make tele-
  phone redemptions on your behalf.
..The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 When Will Redemption Proceeds Be Wired Or Mailed?
 Redemption proceeds will normally be wired or mailed to the recordholder of
 shares as follows:

  .Although redemption proceeds will normally be wired or mailed as
   described above, each Fund reserves the right to pay redemption proceeds
   up to three business days following receipt of a properly executed wire
   transfer redemption request. If you are selling shares you recently paid
   for by check, the Fund will pay you when your check has cleared, which
   may take up to 15 days. If the Federal Reserve Bank is closed on the day
   that the redemption proceeds would ordinarily be wired, wiring the
   redemption proceeds may be delayed one additional business day.
  .A transaction fee of $7.50 may be charged for payments of redemption pro-
   ceeds by wire. Your bank may also charge wiring fees. You should contact
   your bank directly to learn whether it charges such fees.
  .Neither the Trust, Goldman Sachs nor any Authorized Dealer assumes any
   responsibility for the performance of your bank or any intermediaries in
   the transfer process. If a problem with such performance arises, you
   should deal directly with your bank or any such intermediaries.

  .If the redeemed shares were recently paid for by check, the Fund will pay
   the redemption proceeds when the check has cleared, which may take up to

 What Should I Know About The Check Redemption Privilege (Service Shares
 Only)?
 You may elect to have a special account with State Street for the purpose of
 redeeming shares from your account by check. The following general policies
 govern the check redemption privilege:
..You will be provided with a supply of checks when State Street receives a
  completed signature card and authorization form. Checks drawn on the
  account may be payable to the order of any person in any amount over $500,
  but cannot be certified.
  .The payee of the check may cash or deposit it just like any other check
   drawn on a bank.
  .When the check is presented to State Street for payment, a sufficient
   number of full or fractional shares will be redeemed to cover the amount
   of the check.
  .Canceled checks will be returned to you by State Street.
..The check redemption privilege allows you to receive the dividends declared
  on the shares that are to be redeemed until the check is actually proc-
  essed. Because of this feature, accounts may not be completely liquidated
  by check.
..If the amount of the check is greater than the value of the Service Shares
  held in your account, the check will be returned unpaid. In this case, you
  may be subject to extra charges.
..Goldman Sachs Funds reserves the right to limit the availability of, modify
  or terminate the check redemption privilege at any time with respect to any
  or all shareholders.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
 
..Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 
 The Trust reserves the right to:
..Redeem the shares of any account whose balance falls below the minimum as a
  result of earlier redemptions. The Funds will give 60 days' prior written
  notice to allow you to purchase sufficient additional shares of the Fund in
  order to avoid such redemption.
 
                                                                           11-VV
<PAGE>
 
 
..Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction cost upon the disposition of those securities.
..Redeem shares in other circumstances determined by the Board of Trustees to
  be in the best interest of the Trust.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange Service Shares of each Fund and Class B and C Shares of the
 Prime Obligations Portfolio for shares of the same class or an equivalent
 class of any other Goldman Sachs Fund. The exchange privilege may be materi-
 ally modified or withdrawn at a time upon 60 days written notice.

 You should keep in mind the following factors when making or considering an

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

  made depending upon the date and value of your original purchase.
..Automatic exchanges are made monthly on the 15th day of each month or the
  first business day thereafter.
..Minimum dollar amount: $50 per month.
 
 Do I Have Any Reinvestment Privileges With Respect to Class B or C Shares?
 You may redeem Class B or Class C shares of a Fund and reinvest a portion or
 all of the redemption proceeds (plus any additional amounts needed to round
 off purchases to the nearest full share). To be eligible for this privilege,
 you must hold the shares you want to redeem for at least 30 days and must
 reinvest the share proceeds within 90 days after you redeem. You may rein-

  Diversified Portfolio or Class A Shares of any Goldman Sachs Fund at NAV.
  The amount of the CDSC paid upon redemption will not be credited to your
  account.
..If you redeem Class C Shares of the Prime Obligations Portfolio, you may

..You should obtain and read the applicable prospectuses before investing in

..If you redeem Class C Shares, pay a CDSC upon redemption and reinvest in
  Class C Shares subject to the conditions set forth above, your account will
  be credited with the amount of the CDSC previously charged, and the rein-
  vested shares will continue to be subject to a CDSC. In this case, the
  holding period of the Class C Shares acquired through reinvestment for pur-
  poses of computing the CDSC payable upon a subsequent redemption will
  include the holding period of the redeemed shares.
..The reinvestment privilege may be exercised once annually by a shareholder
  upon written request, except that this time limit does not apply to trans-
  actions the sole purpose of which is to reinvest the proceeds at NAV in a
  tax-sheltered retirement plan.
..A reinvesting shareholder may be subject to tax as a result of a redemp-
  tion. Shareholders should consult their own tax advisers concerning the tax
  consequences of a redemption and reinvestment.

 Can I Have Automatic Withdrawals Made On A Regular Basis?
 You may draw on your account systematically via check or ACH transfer in any
 amount of $50 or more.
..It is normally undesirable to maintain a systematic withdrawal plan at the
  same time that you are purchasing additional Class B or Class C Shares
  because of the imposition of a CDSC on your redemptions of Class B or Class
  C Shares.
..You must have a minimum balance of $5,000 in a Fund.
..Checks are mailed on or about the 25th day of each month.
..Each systematic withdrawal is a redemption and therefore a taxable transac-
  tion.
..The CDSC applicable to Class B or Class C Shares redeemed under the system-
  atic withdrawal plan may be waived.
 
 What Types of Reports Will I Be Sent Regarding Investments in Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-526-7384.
 
 What Should I Know When I Purchase Shares Through An Authorized Dealer?
 Authorized Dealers and other financial intermediaries may provide varying
 arrangements for their clients to purchase and redeem Fund shares. They may
 charge
 
                                                                           15-VV

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

 fees and expenses (which affect performance), have different minimum invest-
 ment requirements and are entitled to different services. Information
 regarding these other share classes may be obtained from your sales repre-
 sentative or from Goldman Sachs by calling the number on the back cover of
 this Prospectus.
 
 DISTRIBUTION SERVICES AND FEES
 
 
 What Are The Different Distribution And Service Fees Paid By Service, Class
 B and Class C Shares?
 The Trust has adopted plans (each a "Plan") under which Service, Class B and
 Class C Shares bear service fees and (in the case of Class B and Class C
 Shares) distribution fees paid to Service Organizations and Goldman Sachs.
 If the fees received by Goldman Sachs pursuant to the Plans exceed its
 expenses, Goldman Sachs may realize a profit from this arrangement. Goldman
 Sachs pays the distribution and service fees on a quarterly basis.
 
 Under the Plan for Service Shares, Service Organizations agree to provide
 services in connection with their customers' investments in Service Shares,
 such as:
  .Acting, directly or through an agent, as the sole shareholder of record
  .Maintaining account record for customers
  .Processing orders to purchase, redeem or exchange shares for customers
  .Responding to inquiries from prospective and existing shareholders
  .Assisting customers with investment procedures
 
 For their services, Service Organizations are entitled to receive payments
 from the Trust of up to 0.40% (on an annualized basis) of the average daily
 net assets of the Service Shares of the Funds that are attributable to or
 held in the name of a Service Organization for its customers.
 
 Under the Plans for Class B and Class C Shares, Goldman Sachs is entitled to
 a monthly fee from each Fund for distribution services equal, on an annual
 basis, to 0.75% of a Fund's average daily net assets attributed to Class B
 and Class C Shares. Because these fees are paid out of the Fund's assets on
 an ongoing basis, over time, these fees will increase the cost of your
 investment and may cost you more than paying other types of sales charges.
 
 The distribution fees are subject to the requirements of Rule 12b-1 under
 the 1940 Act, and may be used (among other things) for:
..Compensation paid to and expenses incurred by Authorized Dealers, Goldman
  Sachs and their respective officers, employees and sales representatives;
..Commissions paid to Authorized Dealers;
..Allocable overhead;
 
                                                                           17-VV
<PAGE>
 
 
..Telephone and travel expenses;
..Interest and other costs associated with the financing of such compensation
  and expenses;
..Printing of prospectuses for prospective shareholders;
..Preparation and distribution of sales literature or advertising of any
  type; and
..All other expenses incurred in connection with activities primarily
  intended to result in the sale of Class B and Class C Shares.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.75% distribution fee as an ongoing commission to Authorized Dealers
 after the shares have been held for one year.
 
 PERSONAL ACCOUNT MAINTENANCE SERVICES AND FEES
 
 Under the Plans for Class B and Class C Shares, Goldman Sachs is also enti-
 tled to receive a separate fee equal on an annual basis to 0.25% of each
 Fund's average daily net assets attributed to Class B or Class C Shares.
 This fee is for personal and account maintenance services, and may be used
 to make payments to Goldman Sachs, Authorized Dealers and their officers,
 sales representatives and employees for responding to inquiries of, and fur-
 nishing assistance to, shareholders regarding ownership of their shares or
 their accounts or similar services not otherwise provided on behalf of the
 Funds. If the fees received by Goldman Sachs pursuant to the Plans exceed
 its expenses, Goldman Sachs may realize a profit from this arrangement.

Dividends
 
 All or substantially all of each Fund's net investment income will be
 declared as a dividend daily. Dividends will normally, but not always, be
 declared as of 4:00 p.m. New York time as a dividend and distributed month-
 ly. Shareholders of record may choose to have dividends paid in:
 
..Cash
 
..Additional shares of the same class of the same Fund
 
 Reinvestment in additional shares will not be subject to a CDSC. Service
 Organizations or shareholders may indicate their election on the Account
 Application. Any changes may be submitted in writing to Goldman Sachs at any
 time. If a Service Organization or shareholder does not indicate any choice,
 dividends and distributions will be reinvested automatically in the applica-
 ble Fund.
 
 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and December may be distributed during the
 subsequent calendar year. Although realized gains and losses on the assets
 of a Fund are reflected in the NAV of the Fund, they are not expected to be
 of an amount which would affect the Fund's NAV of $1.00 per share.
 
                                                                               7

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

 U.S. Government securities have historically involved little risk of loss of
 principal if held to maturity. However, no assurance can be given that the
 U.S. Government will provide financial support to U.S. Government agencies,
 authorities, instrumentalities or sponsored enterprises if it is not obli-
 gated to do so by law.
 
 Each Fund may also acquire U.S. Government securities in the form of custo-
 dial receipts. Custodial receipts evidence ownership of future interest pay-
 ments, principal payments or both on notes or bonds issued by the U.S. Gov-
 ernment, its agencies, instrumentalities, political subdivisions or
 authorities. For certain securities law purposes, custodial receipts are not
 considered obligations of the U.S. Government.
 
 Bank Obligations. Bank obligations include certificates of deposit, commer-
 cial paper, unsecured bank promissory notes, bankers' acceptances, time
 deposits and other debt obligations. A Fund may invest in U.S. bank obliga-
 tions when a bank has more than $1 billion in total assets at the time of
 purchase or is a subsidiary of such a bank. Bank obligations may be general
 obligations of the parent bank or may be limited to the issuing branch by
 the terms of the specific obligation or by government regulation.
 
 Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
 asset-backed and receivables-backed securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases installment contracts and personal property. Asset-
 backed and receivables-backed securities are often subject to more rapid
 repayment than their stated maturity date would indicate as a result of the
 pass-through of prepayments of principal on the underlying loans. During
 periods of declining interest rates, prepayment of loans underlying asset-
 backed and receivables-backed securities can be expected to accelerate.
 Accordingly, a Fund's ability to maintain positions in such securities will
 be affected by reductions in the principal amount of such securities result-
 ing from prepayments, and its ability to reinvest the returns of principal
 at comparable yields is subject to generally prevailing interest rates at
 that time. In addition, securities that are backed by credit card, automo-
 bile and similar types of receivables generally do not have the benefit of a
 security interest in collateral that is comparable in quality to mortgage
 assets. There is the possibility that, in some cases, recoveries on
 repossessed collateral may not be available to support payments on these
 securities. In the event of a default, a Fund may suffer a loss if it cannot
 sell collateral quickly and receive the amount it is owed.
 
 
 Repurchase Agreements. Each Fund may enter into repurchase agreements with
 primary dealers in U.S. Government securities and banks affiliated with pri-
 mary dealers. Repurchase agreements involve the purchase of securities sub-
 ject to the
 
2-ZZ
<PAGE>
 
                                                                      Appendix A
 
 seller's agreement to repurchase them at a mutually agreed upon date and
 price. The repurchase price will exceed the original purchase price, the
 difference being income to the Fund, and will be unrelated to the interest
 rate on the purchased security.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund in connection with the repurchase agree-
 ment are less than the repurchase price and Fund's costs associated with
 delay and enforcement of the repurchase agreement. In addition, in the event
 of bankruptcy of the seller, a Fund could suffer additional losses if a
 court determines that the Fund's interest in the collateral is unenforce-
 able.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, each Fund, together with other registered invest-
 ment companies having advisory agreements with the Investment Adviser or any
 of its affiliates, may transfer uninvested cash balances into a single joint
 account, the daily aggregate balance of which will be invested in one or
 more repurchase agreements.
 
 Municipal Obligations. Municipal obligations are issued by or on behalf of
 states, territories and possessions of the United States and their political
 subdivisions, agencies, authorities and instrumentalities, and the District
 of Columbia. Municipal obligations may include fixed rate notes and similar
 debt instruments; variable and floating rate demand instruments; tax-exempt
 commercial paper; municipal bonds; and unrated notes, paper, bonds or other
 instruments.
 
 Municipal Notes and Bonds. Municipal notes include tax anticipation notes
 ("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
 ("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
 notes. Municipal bonds include general obligation bonds and revenue bonds.
 General obligation bonds are backed by the taxing power of the issuing
 municipality and are considered the safest type of municipal obligation.
 Revenue bonds are backed by the revenues of a project or facility such as
 the tolls from a toll bridge. Revenue bonds also include lease rental reve-
 nue bonds which are issued by a state or local authority for capital pro-
 jects and are secured by annual lease payments from the state or locality
 sufficient to cover debt service on the authority's obligations. Industrial
 development bonds ("private activity bonds") are a specific type of revenue
 bond backed by the credit and security of a private user and, therefore,
 have more potential risk. Municipal bonds may be issued in a variety of
 forms, including commercial paper, tender option bonds and variable and
 floating rate securities.
 
                                                                            3-ZZ
<PAGE>
 
 
 
 Tender Option Bonds. A tender option bond is a municipal obligation (gener-
 ally held pursuant to a custodial arrangement) having a relatively long
 maturity and bearing interest at a fixed rate substantially higher than pre-
 vailing short-term, tax-exempt rates. The bond is typically issued in con-
 junction with the agreement of a third party, such as a bank, broker-dealer
 or other financial institution, pursuant to which the institution grants the
 security holder the option, at periodic intervals, to tender its securities
 to the institution. As consideration for providing the option, the financial
 institution receives periodic fees equal to the difference between the
 bond's fixed coupon rate and the rate, as determined by a remarketing or
 similar agent, that would cause the securities, coupled with the tender
 option, to trade at par on the date of such determination. Thus, after pay-
 ment of this fee, the security holder effectively holds a demand obligation
 that bears interest at the prevailing short-term, tax-exempt rate. Certain
 tender option bonds may be illiquid. An institution will normally not be
 obligated to accept tendered bonds in the event of certain defaults or a
 significant downgrading in the credit rating assigned to the issuer of the
 bond. The tender option will be taken into account in determining the matu-
 rity of the tender option bonds and a Fund's average portfolio maturity.
 There is a risk that a Fund will not be considered the owner of a tender
 option bond for federal income tax purposes, and thus will not be entitled
 to treat such interest as exempt from federal income tax.
 
 Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
 issued in anticipation of the issuer's receipt of revenues and present the
 risk that such revenues will be insufficient to satisfy the issuer's payment
 obligations. The entire amount of principal and interest on RAWs is due at
 maturity. RAWs, including those with a maturity of more than 397 days, may
 also be repackaged as instruments which include a demand feature that per-
 mits the holder to sell the RAWs to a bank or other financial institution at
 a purchase price equal to par plus accrued interest on each interest rate
 reset date.
 
 Industrial Development Bonds. The Funds may invest in industrial development
 bonds (private activity bonds), the interest from which would be an item of
 tax preference when distributed by a Fund as "exempt-interest dividends" to
 shareholders under the federal alternative minimum tax.
 
 Other Policies. Certain Funds may invest 25% or more of the value of its
 total assets in municipal obligations which are related in such a way that
 an economic, business or political development or change affecting one
 municipal obligation would also affect the other municipal obligation. For
 example, a Fund may invest all of its assets in (a) municipal obligations
 the interest of which is paid solely from revenues from similar projects
 such as hospitals, electric utility systems, multi-family housing, nursing
 homes, commercial facilities (including hotels),
 
4-ZZ
<PAGE>
 
                                                                      Appendix A
 
 steel companies or life care facilities, (b) municipal obligations whose
 issuers are in the same state, or (c) industrial development obligations.
 Concentration of a Fund's investments in these municipal obligations will
 subject the Fund, to a greater extent than if such investment was not so
 concentrated, to the risks of adverse economic, business or political devel-
 opment affecting the particular state, industry or other area of concentra-
 tion.
 
 Municipal obligations may be backed by letters of credit or other forms of
 credit enhancement issued by domestic banks or foreign banks which have a
 branch, agency or subsidiary in the United States or by other financial
 institutions. The credit quality of these banks and financial institutions
 could, therefore, cause a loss to a Fund that invests in municipal obliga-
 tions. Letters of credit and other obligations of foreign banks and finan-
 cial institutions may involve risks in addition to those of domestic obliga-
 tions because of less publicly-available financial and other information,
 less securities regulation, potential imposition of foreign withholding and
 other taxes, war, expropriation or other adverse governmental actions. For-
 eign banks and their foreign branches are not regulated by U.S. banking
 authorities, and generally are not bound by the accounting, auditing and
 financial reporting standards applicable to U.S. banks. In addition, the
 Funds may acquire securities in the form of custodial receipts which evi-
 dence ownership of future interest payments, principal payments or both on
 obligations of certain state and local governments and authorities.
 
 In order to enhance the liquidity, stability or quality of a municipal obli-
 gation, a Fund may acquire the right to sell the obligation to another party
 at a guaranteed price and date.
 
 Miscellaneous Investments and Policies
 
 Floating and Variable Rate Obligations. The Funds may purchase floating and
 variable rate obligations. The value of these obligations is generally more
 stable than that of a fixed rate obligation in response to changes in inter-
 est rate levels. Subject to the conditions for using amortized cost valua-
 tion under the Investment Company Act, a Fund may consider the maturity of a
 variable or floating rate obligation to be shorter than its ultimate stated
 maturity if the obligation is a U.S. Treasury obligation or U.S. Government
 security, if the obligation has a remaining maturity of 397 calendar days or
 less, or if the obligation has a demand fea ture that permits the Fund to
 receive payment at any time or at specified intervals not exceeding 397 cal-
 endar days. The issuers or financial intermediaries providing demand fea-
 tures may support their ability to purchase the obligations by obtaining
 credit with liquidity supports. These may include lines of credit, which are
 conditional commitments to lend and letters of credit, which will ordinarily
 be irrevocable, both of which may
 
                                                                            5-ZZ
<PAGE>
 
 
 be issued by domestic banks or foreign banks which have a branch, agency or
 subsidiary in the United States. A Fund may purchase variable or floating
 rate obligations from the issuers or may purchase certificates of participa-
 tion, a type of floating or variable rate obligation, which are interests in
 a pool of debt obligations held by a bank or other financial institution.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to a Fund at the time of entering into the transac-
 tion. A forward commitment involves entering into a contract to purchase or
 sell securities for a fixed price at a future date beyond the customary set-
 tlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although a Fund would gener-
 ally purchase securities on a when-issued or forward commitment basis with
 the intention of acquiring the securities for its portfolio, a Fund may dis-
 pose of when-issued securities or forward commitments before settlement
 whenever the Investment Adviser deems it appropriate.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Investment Com-
 pany Act. These limitations include a prohibition on any Fund acquiring more
 than 3% of the voting shares of any other investment company, and a prohibi-
 tion on investing more than 5% of a Fund's total assets in securities of any
 one investment company or more than 10% of its total assets in securities of
 all investment companies. A Fund will indirectly bear its proportionate
 share of any management fees and other expenses paid by such other invest-
 ment companies. Such other investment companies will have investment objec-
 tives, policies and restrictions substantially similar to those of the
 acquiring Fund and will be subject to substantially the same risks.
 
 Illiquid Securities. Each Fund may invest up to 10% of its net assets in
 illiquid securities which cannot be disposed of in seven days in the ordi-
 nary course of business at fair value. Illiquid securities include:
..Both domestic and foreign securities that are not readily marketable
..Certain municipal leases and participation interests
..Certain stripped mortgage-backed securities
..Repurchase agreements and time deposits with a notice or demand period of
  more than seven days

..Certain restricted securities, unless it is determined, based upon a review
  of the trading markets for a specific restricted security, that a
  restricted security is liquid because it is so-called "4(2) commercial
  paper" or is otherwise eligible for resale pursuant to Rule 144A under the
  Securities Act of 1933.
 
 Investing in restricted securities may decrease the liquidity of a Fund's
 portfolio.
 
 Borrowings. Each Fund may borrow up to 33- 1/3% of its total assets from
 banks for temporary or emergency purposes. A Fund may not make additional
 investments if borrowings exceed 5% of its net assets. For more information,
 see the Additional Statement.
 
 Downgraded Securities. After its purchase, a portfolio security may be
 assigned a lower rating or cease to be rated. If this occurs, a Fund may
 continue to hold the security if the Investment Adviser believes it is in
 the best interests of the Fund and its shareholders.
 
 Special Risk Policies Applicable to the Tax-Exempt Diversified Fund:
 
 Fundamental Policies. As a matter of fundamental policy, at least 80% of the
 net assets of the Tax-Exempt Diversified Fund will ordinarily be invested in
 municipal obligations, the interest from which is, in the opinion of bond
 counsel, if any, excluded from gross income for federal income tax purposes.
 
 The Tax-Exempt Diversified Fund may temporarily invest in taxable money mar-
 ket instruments when the Investment Adviser believes that the market condi-
 tions dictate a defensive posture. Investments in taxable money market
 instruments will be limited to those meeting the quality standards of the
 Tax-Exempt Diversified Fund.
 
                                                                            7-ZZ

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

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment adviser to the
 Funds. Goldman Sachs Asset Management is referred to in this Prospectus as
 the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy
 The Money Market Funds are managed to seek maximum current income consistent
 with the preservation of capital and daily liquidity. In managing the Funds,
 the Investment Adviser follows a conservative, risk-managed investment proc-
 ess that seeks to:
..Manage credit risk
..Manage interest rate risk
..Manage liquidity
 
 The Investment Adviser actively manages the Goldman Sachs Money Market Funds
 in designing and structuring the Funds' investment portfolios.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 The Investment Adviser follows a consistent five-step investment process
 across all of its money market portfolios.
 
 1. Define investment objectives and risk parameters
 The Investment Adviser works closely within Fund and Rule 2a-7 guidelines in
 seeking to meet investment objectives for each Fund.
 
 2. Establish benchmarks
 Benchmarks are the IBC Financial Data Universal Averages. Depending upon the
 eligible investments of each Fund, there is a corresponding IBC Index.
 
 3. Establish a risk-managed framework
 Understanding and managing risk is critical to the performance of money mar-
 ket fund portfolios.
 
                                                                            1-CC
<PAGE>
 
 
 
 4. Actively manage the portfolios
 General portfolio strategy meetings are held weekly.
 
 5. Monitor Risk Exposure
 Risk reports enable the Investment Adviser to monitor portfolios on a daily
 basis and track all trading activity.
 
 
.. The Funds: Each Fund's securities are valued by the amortized cost method
   as permitted under Rule 2a-7 of the Investment Company Act of 1940, as
   amended (the "1940 Act"). Under Rule 2a-7, each Fund may invest only in
   U.S. dollar-denominated securities that are determined to present minimal
   credit risk and meet certain other criteria including, conditions relating
   to maturity, diversification and credit quality. These operating policies
   may be more restrictive than the fundamental policies set forth in the
   Statement of Additional Information (the "Additional Statement").
  .   Taxable Funds: Prime Obligations, Money Market, Premium Money Market,
      Treasury Obligations and Government Funds.
  .   Tax-Advantaged Funds: Treasury Instruments and Federal Funds.
  .   Tax-Exempt Funds: Tax-Free Money Market and Municipal Money Market
      Funds.
.. The Investors: The Funds are designed for institutional investors seeking
   a high rate of return, a stable net asset value ("NAV") and convenient
   liquidation privileges. The Funds are particularly suitable for banks,
   corporations and other financial institutions that seek investment of
   short-term funds for their own accounts or for the accounts of their cus-
   tomers. Shares of the Government Fund are intended to qualify as eligible
   investments for federally chartered credit unions pursuant to Sections
   107(7), 107(8) and 107(15) of the Federal Credit Union Act, Part 703 of
   the National Credit Union Administration ("NCUA") Rules and Regulations
   and NCUA Letter Number 155. The Fund intends to review changes in the
   applicable laws, rules and regulations governing eligible investments for
   federally chartered credit unions, and to take such action as may be nec-
   essary so that the investments of the Fund qualify as eligible investments
   under the Federal Credit Union Act and the regulations thereunder. Shares
   of the Government Fund, however, may or may not qualify as eligible
   investments for particular state-chartered credit unions. A state-chart-
   ered credit union should consult qualified legal counsel to determine
   whether the Government Fund is a permissible investment under the law
   applicable to it.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
..  NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
..  Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
   mined pursuant to Rule 2a-7) at the time of purchase.
..  Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
   (as required by Rule 2a-7).
..  Investment Restrictions: Each Fund is subject to certain investment
   restrictions that are described in detail under "Investment Restrictions" in
   the Additional Statement. Fundamental investment restrictions and the
   investment objective of a Fund cannot be changed without approval of a
   majority of the outstanding shares of that Fund. The Treasury Obligations
   Fund's policy of limiting its investments to U.S. Treasury obligations and
   related repurchase agreements is also fundamental. All investment policies
   not specifically designated as fundamental are non-fundamental and may be
   changed without shareholder approval.
..  Diversification. Diversification can help a Fund reduce the risks of
   investing. In accordance with current regulations of the Securities and
   Exchange Commission (the "SEC"), each Fund may not invest more than 5% of the
   value of its total assets at the time of purchase in the securities of any
   single issuer. However, a Fund may invest up to 25% of the value of the total
   assets in the securities of a single issuer for up to three business days.
   These limitations do not apply to cash, certain repurchase agree-ments, U.S.
   Government securities or securities of other investment compa-nies. In
   addition, securities subject to certain unconditional guarantees and
   securities that are not "First Tier Securities" as defined by the SEC are
   subject to different diversification requirements as described in the
   Additional Statement.
                                                                            3-CC

 Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Premium Money Market, Treasury Obliga-
 tions, Treasury Instruments, Government, Federal, Tax-Free Money Market and
 Municipal Money Market Funds seek to maximize current income to the extent
 consistent with the preservation of capital and the maintenance of liquidity
 by investing exclusively in high quality money market instruments.
 
 In order to obtain a rating from a rating organization, the Premium Money
 Market Fund will observe special investment restrictions.
 
 The Treasury Instruments and Federal Funds pursue their investment objec-
 tives by limiting their investments to certain U.S. Treasury obligations and
 U.S. Government securities (each as defined in Appendix A), respectively,
 the interest from which is generally exempt from state income taxation. You
 should consult your tax adviser to determine whether distributions from the
 Treasury Instruments and Federal Funds (and any other Fund that may hold
 such obligations) derived from interest on such obligations are exempt from
 state income taxation in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Free Money Market and Municipal Money Market Funds pursue their
 investment objectives by limiting their investments to securities issued by
 or on behalf of states, territories, and possessions of the United States
 and their political subdivisions, agencies, authorities and instrumentali-
 ties, and the District of Columbia, the interest from which, if any, is in
 the opinion of bond counsel excluded from gross income for federal income
 tax purposes, and with respect to the Tax-Free Money Market Fund, not an
 item of tax preference under the federal alternative minimum tax. With
 respect to the Municipal Money Market Fund, such interest may not necessar-
 ily be exempt from the federal alternative minimum tax.

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

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

Risks that apply to all Funds:
 
..Money Market Risk--The risk that a Fund will not be able to maintain a NAV
  per share of $1.00 at all times.
..Interest Rate Risk--The risk that during periods of rising interest rates,
  a Fund's yield (and the market value of its securities) will tend to be
  lower than prevailing market rates; in periods of falling interest rates, a
  Fund's yield will tend to be higher.
..Credit/Default Risk--The risk that an issuer or guarantor of a security, or
  a bank or other financial institution that has entered into a repurchase
  agreement, may default on its payment obligations.
..Management Risk--The risk that a strategy used by the Investment Adviser
  may fail to produce the intended results.
..Liquidity Risk--The risk that a Fund will be unable to pay redemption pro-
  ceeds within the time period stated in this Prospectus, because of either
  unusual market conditions, an unusually high volume of redemption requests,
  or other reasons.
..Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by
  the "Year 2000 Problem."
 
Risk that applies to the Government and Federal Funds:
 
..Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market, Premium Money Market, Tax-Free Money
Market and Municipal Money Market Funds:
 
..Concentration Risk--The risk that if a Fund invests more than 25% of its
  total assets in issuers within the same state, industry or economic sector,
  an adverse economic, business or political development may affect the value
  of the Fund's investments more than if its investments were not so concen-
  trated.
..Foreign Risk--The risk that a foreign security (or, in the case of the Tax-
  Free Money Market and Municipal Money Market Funds, a foreign letter of
  credit or guarantee) could lose value as a result of political, financial
  and economic events in foreign countries, less stringent foreign securities
  regulations and accounting and disclosure standards, or other factors. The
  Money Market and Premium Money Market Funds may not invest more than 25% of
  their total assets in the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
Risk that applies to the Money Market and Premium Money Market Funds:
 
..Banking Industry Risk--The risk that if a Fund invests more than 25% of its
  total assets in bank obligations, an adverse development in the banking
  industry may affect the value of the Fund's investments more than if a
  Fund's investments were not invested to such a degree in the banking indus-
  try. Normally, the Money Market and Premium Money Market Funds intend to
  invest more than 25% of their total assets in bank obligations. Banks may
  be particularly susceptible to certain economic factors such as interest
  rate changes, adverse developments in the real estate market, fiscal and
  monetary policy and general economic cycles.
 
Risk that applies to the Tax-Free Money Market and Municipal Money Market
Funds:
 
..Tax Risk--The risk that future legislative or administrative changes or
  court decisions may materially affect the ability of a Fund to pay federal
  tax-exempt dividends.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

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

/1/The Funds' annual operating expenses have been restated to reflect current
fees, except for the Municipal Money Market Fund, which are based on estimated
amounts for the current fiscal year.
/2/The Investment Adviser has voluntarily agreed not to impose a portion of the
management fee on the Funds equal to 0.035%. AS A RESULT OF FEE WAIVERS, THE
CURRENT MANAGEMENT FEES OF THE FUNDS ARE 0.17% OF THE FUNDS' AVERAGE DAILY NET
ASSETS. THE WAIVERS MAY BE TERMINATED AT ANY TIME AT THE OPTION OF THE INVEST-
MENT ADVISER.
/3/The Investment Adviser has voluntarily agreed to reduce or limit "Other
Expenses" of each Fund (excluding management fees, taxes, interest, brokerage
fees and litigation, indemnification and other extraordinary expenses) to 0.01%
of each Fund's average daily net assets.

Example
 
The following Example is intended to help you compare the cost of investing in
a Fund (without the waivers and expense limitations) with the cost of investing
in other mutual funds. The Example assumes that you invest $10,000 in FST
Shares of a Fund for the time periods indicated and then redeem all of your
shares at the end of those periods. The Example also assumes that your invest-
ment has a 5% return each year and that a Fund's operating expenses remain the

 INVESTMENT ADVISERS
 
 
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as investment adviser to the Funds. Goldman

 GSAM, together with its affiliates, acted as investment adviser or distribu-
 tor for assets in excess of $  billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
..Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
..Administers each Fund's business affairs
..Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)
 
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter
 into principal transactions in certain taxable money market instruments,
 including repurchase agreements, with Goldman Sachs.

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 The Investment Adviser has voluntarily agreed not to impose a portion of its
 management fee and/or to reduce or otherwise limit the daily expenses of
 each Fund (excluding fees payable under service and administration plans for
 certain share classes, taxes, interest, brokerage and litigation, indemnifi-
 cation and other extraordinary expenses). GSAM may discontinue or modify any
 such reductions or limitations in the future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606, also serves as the Funds'
 transfer agent (the "Transfer Agent") and as such performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," which may lead to computer shutdowns or
 errors (commonly known as the "Year 2000 Problem"). To the extent these sys-
 tems conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 computer systems used by the Investment Adviser or other Fund service prov-
 iders do not adequately address this problem in a timely manner.

 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
..The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
                                                                            3-DD

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

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Shares.
 
 HOW TO BUY SHARES
 
 How Can I Purchase Shares Of The Funds?
 You may purchase Shares of the Funds on any business day at their net asset
 value ("NAV") next determined after receipt of an order. Shares begin earn-
 ing dividends after the receipt of the purchase amount in federal funds. No
 sales load is charged. You may place a purchase order in writing or by tele-
 phone.
 
 --------------------------------------------------------
  By Writing:      Goldman Sachs Funds
                   4900 Sears Tower--60th Floor
                   Chicago, IL 60606-6372
 --------------------------------------------------------
  By Telephone:    1-800-621-2550 (8:00 a.m. to 4:00 p.m.
                    New York time)
 --------------------------------------------------------
 
 In order to make an initial investment in a Fund, you must furnish to the
 Fund or Goldman Sachs the Account Application attached to this Prospectus.
 
 You may send your payment as follows:
..Wire federal funds to The Northern Trust Company ("Northern"), as sub-cus-
  todian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); or
..Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern; or
..Send a check or Federal Reserve draft payable to Goldman Sachs Funds -(Name
  of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
  60606-6372. The Fund will not accept a check drawn on a foreign bank or a
  third-party check.
 
 It is strongly recommended that payment be effected by wiring federal funds
 to Northern.
 
                                                                            1-EE
<PAGE>
 
 
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.
 
 When Do Shares Begin Earning Dividends?
 Dividends begin to accrue as follows:
 
 
  If an effective order and
  federal funds are received:       Dividends begin:
 ----------------------------------------------------

   .After 2:00 p.m. New York time   Next business day
 ----------------------------------------------------
 
 How Do I Purchase Shares Through A Financial Institution?
 
 Certain institutions (including banks, trust companies, brokers and invest-
 ment advisers) that provide recordkeeping, reporting and processing services
 to their customers may be authorized to accept, on behalf of the Trust, pur-
 chase, redemption and exchange orders placed by or on behalf of their cus-
 tomers and may designate other intermediaries to accept such orders, if
 approved by the Trust. In these cases:
.. A Fund will be deemed to have received an order in proper form when the
   order is accepted by the authorized institution or intermediary on a busi-
   ness day, and the order will be priced at the Fund's NAV next determined
   after such acceptance.
.. Authorized institutions or intermediaries will be responsible for transmit-
   ting accepted orders and payments to the Trust within the time period
   agreed upon by them.
 
 You should contact your institution or intermediary directly to learn
 whether it is authorized to accept orders for the Trust.

 These institutions may receive payments from the Funds or Goldman Sachs for
 the services provided by them with respect to the Funds' FST Shares. These
 payments may be in addition to other payments borne by the Funds.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to certain institutions and other persons in
 connection with the sale, distribution and/or servicing of shares of the
 Funds and other Goldman Sachs Funds. Subject to applicable NASD regulations,
 the Investment Adviser, Distributor and/or their affiliates may also con-
 tribute to various cash and non-cash incentive arrangements to promote the
 sale of shares. This additional compensation can vary among institutions
 depending upon such factors as the amounts their customers have invested (or
 may invest) in particular Goldman Sachs Funds, the particular program
 involved, or the amount of reimbursable expenses.
 
 In addition to FST Shares, each Fund also offers other classes of shares to
 investors. These other share classes are subject to different fees and
 expenses (which affect performance) and are entitled to different services
 than FST Shares. Information regarding these other share classes may be
 obtained from your sales representative or from Goldman Sachs by calling the
 number on the back cover of this Prospectus.
 
 What Is My Minimum Investment In The Funds?
 
 
 --------------------------------------------------------
  Minimum initial investment      $10 million
                                  (may be allocated among
                                  the Funds)
 --------------------------------------------------------
  Minimum account balance         $10 million
 --------------------------------------------------------
  Minimum subsequent investments  None
 --------------------------------------------------------
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
..Modify or waive the minimum investment and minimum account balance require-
  ment.
..Reject any purchase order for any reason.
  The Funds may allow you to purchase shares with securities instead of cash
  if consistent with a Fund's investment policies and operations and if
  approved by the Fund's Investment Adviser.
 
                                                                            3-EE
<PAGE>
 
 
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange FST Shares is
 determined by a Fund's NAV. The Funds calculate NAV as follows:
 
                 
                  
            (Value of Assets of the Class) - (Liabilities of the Class)
     NAV = ----------------------------------------------------------------
                     Number of Outstanding Shares of the Class
 
 
                Fund                               NAV Calculated
 ------------------------------------------------------------------------------
  Prime Obligations, Money Market,   As of the close of regular trading of the
   Federal, Tax-Free Money Market,   New York Stock Exchange (usually 4:00 p.m.
   Treasury Instruments and          New York time) on each business day
   Municipal Money Market Funds
 ------------------------------------------------------------------------------
  Premium Money Market, Treasury     As of 5:00 p.m. New York time on
   Obligations and Government Funds  each business day
 ------------------------------------------------------------------------------
 
..NAV per share of each class is calculated by State Street each business
  day. Fund Shares will be priced on any day the New York Stock Exchange is
  open, except for days on which Chicago, Boston or New York banks are closed
  for local holidays.
..On any business day when the Bond Market Association ("BMA") recommends
  that the securities markets close early, each Fund reserves the right to
  close at or prior to the BMA recommended closing time. If a Fund does so,
  it will cease granting same business day credit for purchase and redemption
  orders received after the Fund's closing time and credit will be given to
  the next business day.
..The Trust reserves the right to advance the time by which purchase and
  redemption orders must be received for same business day credit as permit-
  ted by the SEC.
 
 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Generally, each Fund will redeem its FST Shares
 upon request on any business day at their NAV next determined after receipt
 of

 such request in proper form. You may request that redemption proceeds be
 sent to you by check or by wire (if the wire instructions are on record).
 Redemptions may be requested in writing or by telephone.

                    (8:00 a.m. to 4:00 p.m. New York time)
 -------------------------------------------------------------------
 
 Certain institutions and intermediaries are authorized to accept redemption
 requests on behalf of the Funds as described under "How Do I Purchase Shares
 Through A Financial Institution?" A redemption may also be made with respect
 to certain Funds by means of the check redemption privilege described in the
 Additional Statement.
 
 When Do I Need A Signature Guarantee To Redeem Shares?
 Your redemption request must include a signature guarantee if any of the
 following situations apply:
..You would like the redemption proceeds sent to an address that is not your
  address of record; or
..You would like to change the bank designated on your Account Application.
 
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federal savings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.
 
                                                                            5-EE
<PAGE>
 
 
 
 What Do I Need To Know About Telephone Redemption Requests?
 The Trust, the Distributor and the Transfer Agent will not be liable for any
 loss you may incur in the event that the Trust accepts unauthorized tele-
 phone redemption requests that the Trust reasonably believes to be genuine.
 In an effort to prevent unauthorized or fraudulent redemption requests by
 telephone, Goldman Sachs employs reasonable procedures specified by the
 Trust to confirm that such instructions are genuine. If reasonable proce-
 dures are not employed, the Trust may be liable for any loss due to unautho-
 rized or fraudulent transactions. The following general policies are cur-
 rently in effect:
..All telephone requests are recorded.
..Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request will be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
..The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.

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

..Neither the Trust, Goldman Sachs nor any other institution assume any
  responsibility for the performance of your bank or any intermediaries in
  the transfer process. If a problem with such performance arises, you should
  deal directly with your bank or any such intermediaries.
..If the redeemed shares were recently paid for by check, the Fund will pay
  the redemption proceeds when the check has cleared, which may take up to 15
  days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption request:
..Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
 
 The Trust reserves the right to:
..Redeem your shares if your account balance falls below the minimum as a
  result of earlier redemptions. The Funds will give you 60 days' prior writ-
  ten notice to allow you to purchase sufficient additional shares of the
  Fund in order to avoid such redemption.
..Redeem your shares in other circumstances determined by the Board of Trust-
  ees to be in the best interest of the Trust.
..Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange FST Shares of a Fund at NAV for shares of the corresponding
 class of any other Goldman Sachs Fund. The exchange privilege may be materi-
 ally modified or withdrawn at any time upon 60 days' written notice to you.

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

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

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

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

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

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

                                                                      APPENDIX A
 
 larly susceptible to certain economic factors, such as interest rate changes
 and adverse developments in the real estate markets. Fiscal and monetary
 policy and general economic cycles can affect the availability and cost of
 funds, loan demand and asset quality and thereby impact the earnings and
 financial conditions of banks.
 
 Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
 asset-backed and receivables-backed securities, whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed and receivables-backed securities are often subject to more
 rapid repayment than their stated maturity date would indicate as a result
 of the pass-through of prepayments of principal on the underlying loans.
 During periods of declining interest rates, prepayment of loans underlying
 asset-backed and receivables-backed securities can be expected to
 accelerate. Accordingly, a Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. In addition, securities that are backed by
 credit card, automobile and similar types of receivables generally do not
 have the benefit of a security interest in collateral that is comparable in
 quality to mortgage assets. There is the possibility that, in some cases,
 recoveries on repossessed collateral may not be available to support
 payments on these securities. In the event of a default, a Fund may suffer a
 loss if it cannot sell collateral quickly and receive the amount it is owed.
 
 Foreign Government Obligations and Related Foreign Risks. Foreign government
 obligations are U.S. dollar-denominated obligations (limited to commercial
 paper and other notes) issued or guaranteed by a foreign government or other
 entity located or organized in a foreign country that maintains a short-term
 foreign currency rating in the highest short-term ratings category by the
 requisite number of NRSROs.
 
 Investments by a Fund in foreign securities, whether issued by a foreign
 government, bank, corporation or other issuer, may present a greater degree
 of risk than investments in securities of domestic issuers because of less
 publicly-available financial and other information, less securities regula-
 tion, potential imposition of foreign withholding and other taxes, war,
 expropriation or other adverse governmental actions. Foreign banks and their
 foreign branches are not regulated by U.S. banking authorities, and gener-
 ally are not bound by the accounting, auditing and financial reporting stan-
 dards applicable to U.S. banks.
 
                                                                            3-FF
<PAGE>
 
 
 
 Repurchase Agreements. Certain Funds may enter into repurchase agreements
 with primary dealers in U.S. Government securities and banks affiliated with
 primary dealers. Repurchase agreements involve the purchase of securities
 subject to the seller's agreement to repurchase them at a mutually agreed
 upon date and price. The repurchase price will exceed the original purchase
 price, the difference being income to the Fund, and will be unrelated to the
 interest rate on the purchased security.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund in connection with the repurchase agree-
 ment are less than the repurchase price and Fund's costs associated with
 delay and enforcement of the repurchase agreement. In addition, in the event
 of bankruptcy of the seller, a Fund could suffer additional losses if a
 court determines that the Fund's interest in the collateral is not enforce-
 able.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.
 
 Municipal Obligations. Municipal obligations are issued by or on behalf of
 states, territories and possessions of the United States and their political
 subdivisions, agencies, authorities and instrumentalities, and the District
 of Columbia. Municipal obligations may include fixed rate notes and similar
 debt instruments; variable and floating rate demand instruments; tax-exempt
 commercial paper; municipal bonds; and unrated notes, paper, bonds or other
 instruments.
 
 Municipal Notes and Bonds. Municipal notes include tax anticipation notes
 ("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
 ("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
 notes. Municipal bonds include general obligation bonds and revenue bonds.
 General obligation bonds are backed by the taxing power of the issuing
 municipality and are considered the safest type of municipal obligation.
 Revenue bonds are backed by the revenues of a project or facility such as
 the tolls from a toll bridge. Revenue bonds also include lease rental reve-
 nue bonds which are issued by a state or local authority for capital pro-
 jects and are secured by annual lease payments from the state or locality
 sufficient to cover debt service on the authority's obliga-

                                                                      APPENDIX A
 
 tions. Industrial development bonds ("private activity bonds") are a spe-
 cific type of revenue bond backed by the credit and security of a private
 user and, therefore, have more potential risk. Municipal bonds may be issued
 in a variety of forms, including commercial paper, tender option bonds and
 variable and floating rate securities.
 
 Tender Option Bonds. A tender option bond is a municipal obligation (gener-
 ally held pursuant to a custodial arrangement) having a relatively long
 maturity and bearing interest at a fixed rate substantially higher than pre-
 vailing short-term, tax-exempt rates. The bond is typically issued in con-
 junction with the agreement of a third party, such as a bank, broker-dealer
 or other financial institution, pursuant to which the institution grants the
 security holder the option, at periodic intervals, to tender its securities
 to the institution. As consideration for providing the option, the financial
 institution receives periodic fees equal to the difference between the
 bond's fixed coupon rate and the rate, as determined by a remarketing or
 similar agent, that would cause the securities, coupled with the tender
 option, to trade at par on the date of such determination. Thus, after pay-
 ment of this fee, the security holder effectively holds a demand obligation
 that bears interest at the prevailing short-term, tax-exempt rate. Certain
 tender option bonds may be illiquid. An institution will normally not be
 obligated to accept tendered bonds in the event of certain defaults or a
 significant downgrading in the credit rating assigned to the issuer of the
 bond. The tender option will be taken into account in determining the matu-
 rity of the tender option bonds and a Fund's average portfolio maturity.
 There is a risk that a Fund will not be considered the owner of a tender
 option bond for federal income tax purposes, and thus will not be entitled
 to treat such interest as exempt from federal income tax.
 
 Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
 issued in anticipation of the issuer's receipt of revenues and present the
 risk that such revenues will be insufficient to satisfy the issuer's payment
 obligations. The entire amount of principal and interest on RAWs is due at
 maturity. RAWs, including those with a maturity of more than 397 days, may
 also be repackaged as instruments which include a demand feature that per-
 mits the holder to sell the RAWs to a bank or other financial institution at
 a purchase price equal to par plus accrued interest on each interest rate
 reset date.
 
 Industrial Development Bonds. Certain Funds may invest in industrial devel-
 opment bonds (private activity bonds), the interest from which would be an
 item of tax preference when distributed by a Fund as "exempt-interest divi-
 dends" to shareholders under the federal alternative minimum tax.
 
 Other Policies. Certain Funds may invest 25% or more of the value of their
 respective total assets in municipal obligations which are related in such a
 way that an
 
                                                                            5-FF
<PAGE>
 
 
 economic, business or political development or change affecting one munici-
 pal obligation would also affect the other municipal obligation. For exam-
 ple, such Funds may invest all of their respective assets in (a) municipal
 obligations the interest of which is paid solely from revenues from similar
 projects such as hospitals, electric utility systems, multi-family housing,
 nursing homes, commercial facilities (including hotels), steel companies or
 life care facilities, (b) municipal obligations whose issuers are in the
 same state, or (c) industrial development obligations. Concentration of a
 Fund's investments in these municipal obligations will subject the Fund, to
 a greater extent than if such investment was not so concentrated, to the
 risks of adverse economic, business or political developments affecting the
 particular state, industry or other area of concentration.
 
 Municipal obligations may be backed by letters of credit or other forms of
 credit enhancement issued by domestic banks or foreign banks which have a
 branch, agency or subsidiary in the United States or by other financial
 institutions. The credit quality of these banks and financial institutions
 could, therefore, cause a loss to a Fund that invests in municipal obliga-
 tions. Letters of credit and other obligations of foreign banks and finan-
 cial institutions may involve risks in addition to those of domestic obliga-
 tions. See "Foreign Government Obligations and Related Foreign Risks" above.
 In addition, the Funds may acquire securities in the form of custodial
 receipts which evidence ownership of future interest payments, principal
 payments or both on obligations of certain state and local governments and
 authorities.
 
 In order to enhance the liquidity, stability or quality of a municipal obli-
 gation, a Fund may acquire the right to sell the obligation to another party
 at a guaranteed price and date.
 
 Miscellaneous Investments and Policies
 
 Floating and Variable Rate Obligations. The Funds may purchase floating and
 variable rate obligations. The value of these obligations is generally more
 stable than that of a fixed rate obligation in response to changes in inter-
 est rate levels. Subject to the conditions for using amortized cost valua-
 tion under the Investment Company Act, a Fund may consider the maturity of a
 variable or floating rate obligation to be shorter than its ultimate stated
 maturity if the obligation is a U.S. Treasury obligation or U.S. Government
 security, if the obligation has a remaining maturity of 397 calendar days or
 less, or if the obligation has a demand feature that permits the Fund to
 receive payment at any time or at specified intervals not exceeding 397 cal-
 endar days. The issuers or financial intermediaries providing demand fea-
 tures may support their ability to purchase the obligations by obtaining
 credit with liquidity supports. These may include lines of credit, which are
 condi-

                                                                      APPENDIX A
 
 tional commitments to lend and letters of credit, which will ordinarily be
 irrevocable, both of which may be issued by domestic banks or foreign banks
 which have a branch, agency or subsidiary in the United States. A Fund may
 purchase variable or floating rate obligations from the issuers or may pur-
 chase certificates of participation, a type of floating or variable rate
 obligation, which are interests in a pool of debt obligations held by a bank
 or other financial institution.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to a Fund at the time of entering into the transac-
 tion. A forward commitment involves entering into a contract to purchase or
 sell securities for a fixed price at a future date beyond the customary set-
 tlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although a Fund would gener-
 ally purchase securities on a when-issued or forward commitment basis with
 the intention of acquiring the securities for its portfolio, a Fund may dis-
 pose of when-issued securities or forward commitments before settlement
 whenever the Investment Adviser deems it appropriate.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Investment Com-
 pany Act. These limitations include a prohibition on any Fund acquiring more
 than 3% of the voting shares of any other investment company, and a prohibi-
 tion on investing more than 5% of a Fund's total assets in securities of any
 one investment company or more than 10% of its total assets in securities of
 all investment companies. A Fund will indirectly bear its proportionate
 share of any management fees and other expenses paid by such other invest-
 ment companies. Such other investment companies will have investment objec-
 tives, policies and restrictions substantially similar to those of the
 acquiring Fund and will be subject to substantially the same risks.
 
 Illiquid Securities. Each Fund may invest up to 10% of its net assets in
 illiquid securities which cannot be disposed of in seven days in the ordi-
 nary course of business at fair value. Illiquid securities include:
 
  . Both domestic and foreign securities that are not readily marketable
  . Certain municipal leases and participation interests
  . Certain stripped mortgage-backed securities
 
                                                                            7-FF
<PAGE>
 
 
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that a
   restricted security is liquid because it is so-called "4(2) commercial
   paper" or is otherwise eligible for resale pursuant to Rule 144A under the
   Securities Act of 1933.
 
 Investing in restricted securities may decrease the liquidity of a Fund's
 portfolio.
 
 Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from
 banks for temporary or emergency purposes. A Fund may not make additional
 investments if borrowings exceed 5% of its net assets. For more information,
 see the Additional Statement.
 
 Downgraded Securities. After its purchase, a portfolio security may be
 assigned a lower rating or cease to be rated. If this occurs, a Fund may
 continue to hold the security if the Investment Adviser believes it is in
 the best interests of the Fund and its shareholders.

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

  PASSED UPON THE ADEQUACY OF THIS PROSPECTUS.
  ANY REPRESENTATION TO THE CONTRARY IS A

  AN INVESTMENT IN A FUND IS NOT A BANK DEPOSIT
  AND IS NOT INSURED BY THE FEDERAL DEPOSIT
  INSURANCE CORPORATION OR ANY OTHER GOVERNMENT
  AGENCY. ALTHOUGH A FUND SEEKS TO PRESERVE THE
  VALUE OF YOUR INVESTMENT AT $1.00 PER SHARE,
  IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN A
  FUND.

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment adviser to the
 Funds. Goldman Sachs Asset Management is referred to in this Prospectus as
 the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy
 The Money Market Funds are managed to seek maximum current income consistent
 with the preservation of capital and daily liquidity. In managing the Funds,
 the Investment Adviser follows a conservative, risk-managed investment proc-
 ess that seeks to:
..Manage credit risk
..Manage interest rate risk
..Manage liquidity
 
 The Investment Adviser actively manages the Goldman Sachs Money Market Funds
 in designing and structuring the Funds' investment portfolios.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 The Investment Adviser follows a consistent five-step investment process
 across all of its money market portfolios.
 
 1. Define investment objectives and risk parameters
 The Investment Adviser works closely within Fund and Rule 2a-7 guidelines in
 seeking to meet investment objectives for each Fund.
 
 2. Establish benchmarks
 Benchmarks are the IBC Financial Data Universal Averages. Depending upon the
 eligible investments of each Fund, there is a corresponding IBC Index.
 
 3. Establish a risk-managed framework
 Understanding and managing risk is critical to the performance of money mar-
 ket fund portfolios.
 
                                                                            1-CC
<PAGE>
 
 
 
 4. Actively manage the portfolios
 General portfolio strategy meetings are held weekly.
 
 5. Monitor Risk Exposure
 Risk reports enable the Investment Adviser to monitor portfolios on a daily
 basis and track all trading activity.
 
 
.. The Funds: Each Fund's securities are valued by the amortized cost method
   as permitted under Rule 2a-7 of the Investment Company Act of 1940, as
   amended (the "1940 Act"). Under Rule 2a-7, each Fund may invest only in
   U.S. dollar-denominated securities that are determined to present minimal
   credit risk and meet certain other criteria including, conditions relating
   to maturity, diversification and credit quality. These operating policies
   may be more restrictive than the fundamental policies set forth in the
   Statement of Additional Information (the "Additional Statement").
  .   Taxable Funds: Prime Obligations, Money Market, Premium Money Market,
      Treasury Obligations and Government Funds.
  .   Tax-Advantaged Funds: Treasury Instruments and Federal Funds.
  .   Tax-Exempt Funds: Tax-Free Money Market and Municipal Money Market
      Funds.
.. The Investors: The Funds are designed for institutional investors seeking
   a high rate of return, a stable net asset value ("NAV") and convenient
   liquidation privileges. The Funds are particularly suitable for banks,
   corporations and other financial institutions that seek investment of
   short-term funds for their own accounts or for the accounts of their cus-
   tomers. Shares of the Government Fund are intended to qualify as eligible
   investments for federally chartered credit unions pursuant to Sections
   107(7), 107(8) and 107(15) of the Federal Credit Union Act, Part 703 of
   the National Credit Union Administration ("NCUA") Rules and Regulations
   and NCUA Letter Number 155. The Fund intends to review changes in the
   applicable laws, rules and regulations governing eligible investments for
   federally chartered credit unions, and to take such action as may be nec-
   essary so that the investments of the Fund qualify as eligible investments
   under the Federal Credit Union Act and the regulations thereunder. Shares
   of the Government Fund, however, may or may not qualify as eligible
   investments for particular state-chartered credit unions. A state-chart-
   ered credit union should consult qualified legal counsel to determine
   whether the Government Fund is a permissible investment under the law
   applicable to it.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
..  NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
..  Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
   mined pursuant to Rule 2a-7) at the time of purchase.
..  Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
   (as required by Rule 2a-7).
..  Investment Restrictions: Each Fund is subject to certain investment
   restrictions that are described in detail under "Investment Restrictions" in
   the Additional Statement. Fundamental investment restrictions and the
   investment objective of a Fund cannot be changed without approval of a
   majority of the outstanding shares of that Fund. The Treasury Obligations
   Fund's policy of limiting its investments to U.S. Treasury obligations and
   related repurchase agreements is also fundamental. All investment policies
   not specifically designated as fundamental are non-fundamental and may be
   changed without shareholder approval.
..  Diversification. Diversification can help a Fund reduce the risks of
   investing. In accordance with current regulations of the Securities and
   Exchange Commission (the "SEC"), each Fund may not invest more than 5% of the
   value of its total assets at the time of purchase in the securities of any
   single issuer. However, a Fund may invest up to 25% of the value of the total
   assets in the securities of a single issuer for up to three business days.
   These limitations do not apply to cash, certain repurchase agree-ments, U.S.
   Government securities or securities of other investment compa-nies. In
   addition, securities subject to certain unconditional guarantees and
   securities that are not "First Tier Securities" as defined by the SEC are
   subject to different diversification requirements as described in the
   Additional Statement.
                                                                            3-CC

 Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Premium Money Market, Treasury Obliga-
 tions, Treasury Instruments, Government, Federal, Tax-Free Money Market and
 Municipal Money Market Funds seek to maximize current income to the extent
 consistent with the preservation of capital and the maintenance of liquidity
 by investing exclusively in high quality money market instruments.
 
 In order to obtain a rating from a rating organization, the Premium Money
 Market Fund will observe special investment restrictions.
 
 The Treasury Instruments and Federal Funds pursue their investment objec-
 tives by limiting their investments to certain U.S. Treasury obligations and
 U.S. Government securities (each as defined in Appendix A), respectively,
 the interest from which is generally exempt from state income taxation. You
 should consult your tax adviser to determine whether distributions from the
 Treasury Instruments and Federal Funds (and any other Fund that may hold
 such obligations) derived from interest on such obligations are exempt from
 state income taxation in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Free Money Market and Municipal Money Market Funds pursue their
 investment objectives by limiting their investments to securities issued by
 or on behalf of states, territories, and possessions of the United States
 and their political subdivisions, agencies, authorities and instrumentali-
 ties, and the District of Columbia, the interest from which, if any, is in
 the opinion of bond counsel excluded from gross income for federal income
 tax purposes, and with respect to the Tax-Free Money Market Fund, not an
 item of tax preference under the federal alternative minimum tax. With
 respect to the Municipal Money Market Fund, such interest may not necessar-
 ily be exempt from the federal alternative minimum tax.

   offs and declines in total deposits) the Funds may, for temporary defensive
   purposes, invest less than 25% of their total assets in bank obligations.
 /2/To the extent required by Rule 2a-7, asset-backed and receivables-backed
   securities will be rated by the requisite number of nationally recognized
   statistical rating organizations ("NRSROs").

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

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

Risks that apply to all Funds:
 
..Money Market Risk--The risk that a Fund will not be able to maintain a NAV
  per share of $1.00 at all times.
..Interest Rate Risk--The risk that during periods of rising interest rates,
  a Fund's yield (and the market value of its securities) will tend to be
  lower than prevailing market rates; in periods of falling interest rates, a
  Fund's yield will tend to be higher.
..Credit/Default Risk--The risk that an issuer or guarantor of a security, or
  a bank or other financial institution that has entered into a repurchase
  agreement, may default on its payment obligations.
..Management Risk--The risk that a strategy used by the Investment Adviser
  may fail to produce the intended results.
..Liquidity Risk--The risk that a Fund will be unable to pay redemption pro-
  ceeds within the time period stated in this Prospectus, because of either
  unusual market conditions, an unusually high volume of redemption requests,
  or other reasons.
..Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by
  the "Year 2000 Problem."
 
Risk that applies to the Government and Federal Funds:
 
..Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market, Premium Money Market, Tax-Free Money
Market and Municipal Money Market Funds:
 
..Concentration Risk--The risk that if a Fund invests more than 25% of its
  total assets in issuers within the same state, industry or economic sector,
  an adverse economic, business or political development may affect the value
  of the Fund's investments more than if its investments were not so concen-
  trated.
..Foreign Risk--The risk that a foreign security (or, in the case of the Tax-
  Free Money Market and Municipal Money Market Funds, a foreign letter of
  credit or guarantee) could lose value as a result of political, financial
  and economic events in foreign countries, less stringent foreign securities
  regulations and accounting and disclosure standards, or other factors. The
  Money Market and Premium Money Market Funds may not invest more than 25% of
  their total assets in the securities of any one foreign government.

Risk that applies to the Money Market and Premium Money Market Funds:
 
..Banking Industry Risk--The risk that if a Fund invests more than 25% of its
  total assets in bank obligations, an adverse development in the banking
  industry may affect the value of the Fund's investments more than if a
  Fund's investments were not invested to such a degree in the banking indus-
  try. Normally, the Money Market and Premium Money Market Funds intend to
  invest more than 25% of their total assets in bank obligations. Banks may
  be particularly susceptible to certain economic factors such as interest
  rate changes, adverse developments in the real estate market, fiscal and
  monetary policy and general economic cycles.
 
Risk that applies to the Tax-Free Money Market and Municipal Money Market
Funds:
 
..Tax Risk--The risk that future legislative or administrative changes or
  court decisions may materially affect the ability of a Fund to pay federal
  tax-exempt dividends.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Admin-
 istration Shares from year to year; and (b) how the average annual returns
 of a Fund's Administration Shares compare to the returns of a composite of
 mutual funds with similar investment objectives. The bar chart and table
 assume reinvestment of dividends and distributions. A Fund's past perfor-
 mance is not necessarily an indication of how the Fund will perform in the
 future. Performance reflects expense limitations in effect. If expense limi-
 tations were not in place, a Fund's performance would have been reduced. You
 may obtain a Fund's current yield by calling 1-800-621-2550. No information
 has been provided for the Municipal Money Market Fund because it has not yet
 commenced operations.

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

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

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

Service Providers
 
 INVESTMENT ADVISERS
 
 
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as investment adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. As of April  , 1999,
 GSAM, together with its affiliates, acted as investment adviser or distribu-
 tor for assets in excess of $  billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
..Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
..Administers each Fund's business affairs
..Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)
 
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter
 into principal transactions in certain taxable money market instruments,
 including repurchase agreements, with Goldman Sachs.
 
 MANAGEMENT FEES
 
 
 As compensation for its services and its assumption of certain expenses, the
 Investment Adviser is entitled to the following fees, computed daily and

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 The Investment Adviser has voluntarily agreed not to impose a portion of its
 management fee and/or to reduce or otherwise limit the daily expenses of
 each Fund (excluding fees payable under service and administration plans for
 certain share classes, taxes, interest, brokerage and litigation, indemnifi-
 cation and other extraordinary expenses). GSAM may discontinue or modify any
 such reductions or limitations in the future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606, also serves as the Funds'
 transfer agent (the "Transfer Agent") and as such performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," which may lead to computer shutdowns or
 errors (commonly known as the "Year 2000 Problem"). To the extent these sys-
 tems conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 computer systems used by the Investment Adviser or other Fund service prov-
 iders do not adequately address this problem in a timely manner.

 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
..The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
                                                                            3-DD

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

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

  By Writing:      Goldman Sachs Funds
                   4900 Sears Tower - 60th Floor
                   Chicago, IL 60606-6372
 --------------------------------------------------------
  By Telephone:    1-800-621-2550
                   (8:00 a.m. to 4:00 p.m. New York time)
 --------------------------------------------------------
 Before or immediately after placing an initial purchase order, a Service
 Organization should complete and send to Goldman Sachs the Account Applica-
 tion. Subsequent purchase orders should be accompanied by information iden-
 tifying the account and the Fund in which Administration Shares are to be
 purchased.
 
 Service Organizations may send their payments as follows:
..Wire federal funds to The Northern Trust Company ("Northern"), as sub-
  custodian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); or
 
                                                                            1-II
<PAGE>
 
..Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern, as sub-custodian for State Street;
  or
..Send a check or Federal Reserve draft payable to Goldman Sachs Funds --
  (Name of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago,
  IL 60606-6372. The Fund will not accept a check drawn on a foreign bank or
  a third-party check.
 
 It is strongly recommended that payment be effected by wiring federal funds
 to Northern.
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.
 
 When Do Shares Begin Earning Dividends?
 Dividends begin to accrue as follows:

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

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

 What Is My Minimum Investment In The Funds?
 
 
 ----------------------------------------------------
  Minimum initial investment      $10 million (may be
                                  allocated among the
                                  Funds)
 ----------------------------------------------------
  Minimum account balance         $10 million
 ----------------------------------------------------
  Minimum subsequent investments  None
 ----------------------------------------------------
 
 A Service Organization may impose a minimum amount for initial and subse-
 quent investments in Administration Shares and may establish other require-
 ments such as a minimum account balance. A Service Organization may redeem
 Administration Shares held by non-complying accounts, and may impose a
 charge for any special services.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
..Modify or waive the minimum investment and minimum account balance require-
  ment.
..Reject any purchase order for any reason.
 The Funds may allow Service Organizations to purchase shares with securities
 instead of cash if consistent with a Fund's investment policies and opera-
 tions and if approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Administration
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
             (Value of Assets of the Class) - (Liabilities of the Class)
     NAV = ---------------------------------------------------------------
                   Number of Outstanding Shares of the Class

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

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

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

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

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

 What Types Of Reports Will I Be Sent Regarding Investments In Administration
 Shares?
 Service Organizations will receive annual reports containing audited finan-
 cial statements and semiannual reports. Upon request, Service Organizations
 will also be provided with a printed confirmation for each transaction. Any
 dividends and distributions paid by the Funds are also reflected in regular
 statements issued by Goldman Sachs to Service Organizations. Service Organi-
 zations are responsible for providing these or other reports to their cus-
 tomers who are the beneficial owners of Administration Shares in accordance
 with the rules that apply to their accounts with the Service Organizations.

Dividends
 
 Dividends will be distributed to Service Organizations monthly. Service
 Organizations may choose to have dividends paid in:
..Cash
..Additional shares of the same class of the same Fund
 
 Service Organizations may indicate their election on the Account Applica-
 tion. Any changes may be submitted in writing to Goldman Sachs at any time.
 If a Service Organization does not indicate any choice, dividends and dis-
 tributions will be reinvested automatically in the applicable Fund.
 
 All or substantially all of each Fund's net investment income will be
 declared as a dividend daily. Dividends will normally, but not always, be
 declared as of the following times:

 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and
 
                                                                              17

 December may be distributed during the subsequent calendar year. Although
 realized gains and losses on the assets of a Fund are reflected in the NAV
 of the Fund, they are not expected to be of an amount which would affect the
 Fund's NAV of $1.00 per share.
 
 The income declared as a dividend for the Treasury Obligations, Government

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

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

 larly susceptible to certain economic factors, such as interest rate changes
 and adverse developments in the real estate markets. Fiscal and monetary
 policy and general economic cycles can affect the availability and cost of
 funds, loan demand and asset quality and thereby impact the earnings and
 financial conditions of banks.
 
 Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
 asset-backed and receivables-backed securities, whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed and receivables-backed securities are often subject to more
 rapid repayment than their stated maturity date would indicate as a result
 of the pass-through of prepayments of principal on the underlying loans.
 During periods of declining interest rates, prepayment of loans underlying
 asset-backed and receivables-backed securities can be expected to
 accelerate. Accordingly, a Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. In addition, securities that are backed by
 credit card, automobile and similar types of receivables generally do not
 have the benefit of a security interest in collateral that is comparable in
 quality to mortgage assets. There is the possibility that, in some cases,
 recoveries on repossessed collateral may not be available to support
 payments on these securities. In the event of a default, a Fund may suffer a
 loss if it cannot sell collateral quickly and receive the amount it is owed.
 
 Foreign Government Obligations and Related Foreign Risks. Foreign government
 obligations are U.S. dollar-denominated obligations (limited to commercial
 paper and other notes) issued or guaranteed by a foreign government or other
 entity located or organized in a foreign country that maintains a short-term
 foreign currency rating in the highest short-term ratings category by the
 requisite number of NRSROs.
 
 Investments by a Fund in foreign securities, whether issued by a foreign
 government, bank, corporation or other issuer, may present a greater degree
 of risk than investments in securities of domestic issuers because of less
 publicly-available financial and other information, less securities regula-
 tion, potential imposition of foreign withholding and other taxes, war,
 expropriation or other adverse governmental actions. Foreign banks and their
 foreign branches are not regulated by U.S. banking authorities, and gener-
 ally are not bound by the accounting, auditing and financial reporting stan-
 dards applicable to U.S. banks.
 
                                                                            3-FF
<PAGE>
 
 
 
 Repurchase Agreements. Certain Funds may enter into repurchase agreements
 with primary dealers in U.S. Government securities and banks affiliated with
 primary dealers. Repurchase agreements involve the purchase of securities
 subject to the seller's agreement to repurchase them at a mutually agreed
 upon date and price. The repurchase price will exceed the original purchase
 price, the difference being income to the Fund, and will be unrelated to the
 interest rate on the purchased security.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund in connection with the repurchase agree-
 ment are less than the repurchase price and Fund's costs associated with
 delay and enforcement of the repurchase agreement. In addition, in the event
 of bankruptcy of the seller, a Fund could suffer additional losses if a
 court determines that the Fund's interest in the collateral is not enforce-
 able.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.
 
 Municipal Obligations. Municipal obligations are issued by or on behalf of
 states, territories and possessions of the United States and their political
 subdivisions, agencies, authorities and instrumentalities, and the District
 of Columbia. Municipal obligations may include fixed rate notes and similar
 debt instruments; variable and floating rate demand instruments; tax-exempt
 commercial paper; municipal bonds; and unrated notes, paper, bonds or other
 instruments.
 
 Municipal Notes and Bonds. Municipal notes include tax anticipation notes
 ("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
 ("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
 notes. Municipal bonds include general obligation bonds and revenue bonds.
 General obligation bonds are backed by the taxing power of the issuing
 municipality and are considered the safest type of municipal obligation.
 Revenue bonds are backed by the revenues of a project or facility such as
 the tolls from a toll bridge. Revenue bonds also include lease rental reve-
 nue bonds which are issued by a state or local authority for capital pro-
 jects and are secured by annual lease payments from the state or locality
 sufficient to cover debt service on the authority's obliga-

                                                                      APPENDIX A
 
 tions. Industrial development bonds ("private activity bonds") are a spe-
 cific type of revenue bond backed by the credit and security of a private
 user and, therefore, have more potential risk. Municipal bonds may be issued
 in a variety of forms, including commercial paper, tender option bonds and
 variable and floating rate securities.
 
 Tender Option Bonds. A tender option bond is a municipal obligation (gener-
 ally held pursuant to a custodial arrangement) having a relatively long
 maturity and bearing interest at a fixed rate substantially higher than pre-
 vailing short-term, tax-exempt rates. The bond is typically issued in con-
 junction with the agreement of a third party, such as a bank, broker-dealer
 or other financial institution, pursuant to which the institution grants the
 security holder the option, at periodic intervals, to tender its securities
 to the institution. As consideration for providing the option, the financial
 institution receives periodic fees equal to the difference between the
 bond's fixed coupon rate and the rate, as determined by a remarketing or
 similar agent, that would cause the securities, coupled with the tender
 option, to trade at par on the date of such determination. Thus, after pay-
 ment of this fee, the security holder effectively holds a demand obligation
 that bears interest at the prevailing short-term, tax-exempt rate. Certain
 tender option bonds may be illiquid. An institution will normally not be
 obligated to accept tendered bonds in the event of certain defaults or a
 significant downgrading in the credit rating assigned to the issuer of the
 bond. The tender option will be taken into account in determining the matu-
 rity of the tender option bonds and a Fund's average portfolio maturity.
 There is a risk that a Fund will not be considered the owner of a tender
 option bond for federal income tax purposes, and thus will not be entitled
 to treat such interest as exempt from federal income tax.
 
 Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
 issued in anticipation of the issuer's receipt of revenues and present the
 risk that such revenues will be insufficient to satisfy the issuer's payment
 obligations. The entire amount of principal and interest on RAWs is due at
 maturity. RAWs, including those with a maturity of more than 397 days, may
 also be repackaged as instruments which include a demand feature that per-
 mits the holder to sell the RAWs to a bank or other financial institution at
 a purchase price equal to par plus accrued interest on each interest rate
 reset date.
 
 Industrial Development Bonds. Certain Funds may invest in industrial devel-
 opment bonds (private activity bonds), the interest from which would be an
 item of tax preference when distributed by a Fund as "exempt-interest divi-
 dends" to shareholders under the federal alternative minimum tax.
 
 Other Policies. Certain Funds may invest 25% or more of the value of their
 respective total assets in municipal obligations which are related in such a
 way that an
 
                                                                            5-FF
<PAGE>
 
 
 economic, business or political development or change affecting one munici-
 pal obligation would also affect the other municipal obligation. For exam-
 ple, such Funds may invest all of their respective assets in (a) municipal
 obligations the interest of which is paid solely from revenues from similar
 projects such as hospitals, electric utility systems, multi-family housing,
 nursing homes, commercial facilities (including hotels), steel companies or
 life care facilities, (b) municipal obligations whose issuers are in the
 same state, or (c) industrial development obligations. Concentration of a
 Fund's investments in these municipal obligations will subject the Fund, to
 a greater extent than if such investment was not so concentrated, to the
 risks of adverse economic, business or political developments affecting the
 particular state, industry or other area of concentration.
 
 Municipal obligations may be backed by letters of credit or other forms of
 credit enhancement issued by domestic banks or foreign banks which have a
 branch, agency or subsidiary in the United States or by other financial
 institutions. The credit quality of these banks and financial institutions
 could, therefore, cause a loss to a Fund that invests in municipal obliga-
 tions. Letters of credit and other obligations of foreign banks and finan-
 cial institutions may involve risks in addition to those of domestic obliga-
 tions. See "Foreign Government Obligations and Related Foreign Risks" above.
 In addition, the Funds may acquire securities in the form of custodial
 receipts which evidence ownership of future interest payments, principal
 payments or both on obligations of certain state and local governments and
 authorities.
 
 In order to enhance the liquidity, stability or quality of a municipal obli-
 gation, a Fund may acquire the right to sell the obligation to another party
 at a guaranteed price and date.
 
 Miscellaneous Investments and Policies
 
 Floating and Variable Rate Obligations. The Funds may purchase floating and
 variable rate obligations. The value of these obligations is generally more
 stable than that of a fixed rate obligation in response to changes in inter-
 est rate levels. Subject to the conditions for using amortized cost valua-
 tion under the Investment Company Act, a Fund may consider the maturity of a
 variable or floating rate obligation to be shorter than its ultimate stated
 maturity if the obligation is a U.S. Treasury obligation or U.S. Government
 security, if the obligation has a remaining maturity of 397 calendar days or
 less, or if the obligation has a demand feature that permits the Fund to
 receive payment at any time or at specified intervals not exceeding 397 cal-
 endar days. The issuers or financial intermediaries providing demand fea-
 tures may support their ability to purchase the obligations by obtaining
 credit with liquidity supports. These may include lines of credit, which are
 condi-

                                                                      APPENDIX A
 
 tional commitments to lend and letters of credit, which will ordinarily be
 irrevocable, both of which may be issued by domestic banks or foreign banks
 which have a branch, agency or subsidiary in the United States. A Fund may
 purchase variable or floating rate obligations from the issuers or may pur-
 chase certificates of participation, a type of floating or variable rate
 obligation, which are interests in a pool of debt obligations held by a bank
 or other financial institution.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to a Fund at the time of entering into the transac-
 tion. A forward commitment involves entering into a contract to purchase or
 sell securities for a fixed price at a future date beyond the customary set-
 tlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although a Fund would gener-
 ally purchase securities on a when-issued or forward commitment basis with
 the intention of acquiring the securities for its portfolio, a Fund may dis-
 pose of when-issued securities or forward commitments before settlement
 whenever the Investment Adviser deems it appropriate.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Investment Com-
 pany Act. These limitations include a prohibition on any Fund acquiring more
 than 3% of the voting shares of any other investment company, and a prohibi-
 tion on investing more than 5% of a Fund's total assets in securities of any
 one investment company or more than 10% of its total assets in securities of
 all investment companies. A Fund will indirectly bear its proportionate
 share of any management fees and other expenses paid by such other invest-
 ment companies. Such other investment companies will have investment objec-
 tives, policies and restrictions substantially similar to those of the
 acquiring Fund and will be subject to substantially the same risks.
 
 Illiquid Securities. Each Fund may invest up to 10% of its net assets in
 illiquid securities which cannot be disposed of in seven days in the ordi-
 nary course of business at fair value. Illiquid securities include:
 
  . Both domestic and foreign securities that are not readily marketable
  . Certain municipal leases and participation interests
  . Certain stripped mortgage-backed securities
 
                                                                            7-FF
<PAGE>
 
 
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that a
   restricted security is liquid because it is so-called "4(2) commercial
   paper" or is otherwise eligible for resale pursuant to Rule 144A under the
   Securities Act of 1933.
 
 Investing in restricted securities may decrease the liquidity of a Fund's
 portfolio.
 
 Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from
 banks for temporary or emergency purposes. A Fund may not make additional
 investments if borrowings exceed 5% of its net assets. For more information,
 see the Additional Statement.
 
 Downgraded Securities. After its purchase, a portfolio security may be
 assigned a lower rating or cease to be rated. If this occurs, a Fund may
 continue to hold the security if the Investment Adviser believes it is in
 the best interests of the Fund and its shareholders.

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

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment adviser to the
 Funds. Goldman Sachs Asset Management is referred to in this Prospectus as
 the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy
 The Money Market Funds are managed to seek maximum current income consistent
 with the preservation of capital and daily liquidity. In managing the Funds,
 the Investment Adviser follows a conservative, risk-managed investment proc-
 ess that seeks to:
..Manage credit risk
..Manage interest rate risk
..Manage liquidity
 
 The Investment Adviser actively manages the Goldman Sachs Money Market Funds
 in designing and structuring the Funds' investment portfolios.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 The Investment Adviser follows a consistent five-step investment process
 across all of its money market portfolios.
 
 1. Define investment objectives and risk parameters
 The Investment Adviser works closely within Fund and Rule 2a-7 guidelines in
 seeking to meet investment objectives for each Fund.
 
 2. Establish benchmarks
 Benchmarks are the IBC Financial Data Universal Averages. Depending upon the
 eligible investments of each Fund, there is a corresponding IBC Index.
 
 3. Establish a risk-managed framework
 Understanding and managing risk is critical to the performance of money mar-
 ket fund portfolios.
 
                                                                            1-CC
<PAGE>
 
 
 
 4. Actively manage the portfolios
 General portfolio strategy meetings are held weekly.
 
 5. Monitor Risk Exposure
 Risk reports enable the Investment Adviser to monitor portfolios on a daily
 basis and track all trading activity.
 
 
.. The Funds: Each Fund's securities are valued by the amortized cost method
   as permitted under Rule 2a-7 of the Investment Company Act of 1940, as
   amended (the "1940 Act"). Under Rule 2a-7, each Fund may invest only in
   U.S. dollar-denominated securities that are determined to present minimal
   credit risk and meet certain other criteria including, conditions relating
   to maturity, diversification and credit quality. These operating policies
   may be more restrictive than the fundamental policies set forth in the
   Statement of Additional Information (the "Additional Statement").
  .   Taxable Funds: Prime Obligations, Money Market, Premium Money Market,
      Treasury Obligations and Government Funds.
  .   Tax-Advantaged Funds: Treasury Instruments and Federal Funds.
  .   Tax-Exempt Funds: Tax-Free Money Market and Municipal Money Market
      Funds.
.. The Investors: The Funds are designed for institutional investors seeking
   a high rate of return, a stable net asset value ("NAV") and convenient
   liquidation privileges. The Funds are particularly suitable for banks,
   corporations and other financial institutions that seek investment of
   short-term funds for their own accounts or for the accounts of their cus-
   tomers. Shares of the Government Fund are intended to qualify as eligible
   investments for federally chartered credit unions pursuant to Sections
   107(7), 107(8) and 107(15) of the Federal Credit Union Act, Part 703 of
   the National Credit Union Administration ("NCUA") Rules and Regulations
   and NCUA Letter Number 155. The Fund intends to review changes in the
   applicable laws, rules and regulations governing eligible investments for
   federally chartered credit unions, and to take such action as may be nec-
   essary so that the investments of the Fund qualify as eligible investments
   under the Federal Credit Union Act and the regulations thereunder. Shares
   of the Government Fund, however, may or may not qualify as eligible
   investments for particular state-chartered credit unions. A state-chart-
   ered credit union should consult qualified legal counsel to determine
   whether the Government Fund is a permissible investment under the law
   applicable to it.

                                          GENERAL INVESTMENT MANAGEMENT APPROACH
 
..  NAV: Each Fund seeks to maintain a stable NAV of $1.00 per share.
..  Maximum Remaining Maturity of Portfolio Investments: 13 months (as deter-
   mined pursuant to Rule 2a-7) at the time of purchase.
..  Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
   (as required by Rule 2a-7).
..  Investment Restrictions: Each Fund is subject to certain investment
   restrictions that are described in detail under "Investment Restrictions" in
   the Additional Statement. Fundamental investment restrictions and the
   investment objective of a Fund cannot be changed without approval of a
   majority of the outstanding shares of that Fund. The Treasury Obligations
   Fund's policy of limiting its investments to U.S. Treasury obligations and
   related repurchase agreements is also fundamental. All investment policies
   not specifically designated as fundamental are non-fundamental and may be
   changed without shareholder approval.
..  Diversification. Diversification can help a Fund reduce the risks of
   investing. In accordance with current regulations of the Securities and
   Exchange Commission (the "SEC"), each Fund may not invest more than 5% of the
   value of its total assets at the time of purchase in the securities of any
   single issuer. However, a Fund may invest up to 25% of the value of the total
   assets in the securities of a single issuer for up to three business days.
   These limitations do not apply to cash, certain repurchase agree-ments, U.S.
   Government securities or securities of other investment compa-nies. In
   addition, securities subject to certain unconditional guarantees and
   securities that are not "First Tier Securities" as defined by the SEC are
   subject to different diversification requirements as described in the
   Additional Statement.
                                                                            3-CC

 Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Premium Money Market, Treasury Obliga-
 tions, Treasury Instruments, Government, Federal, Tax-Free Money Market and
 Municipal Money Market Funds seek to maximize current income to the extent
 consistent with the preservation of capital and the maintenance of liquidity
 by investing exclusively in high quality money market instruments.
 
 In order to obtain a rating from a rating organization, the Premium Money
 Market Fund will observe special investment restrictions.
 
 The Treasury Instruments and Federal Funds pursue their investment objec-
 tives by limiting their investments to certain U.S. Treasury obligations and
 U.S. Government securities (each as defined in Appendix A), respectively,
 the interest from which is generally exempt from state income taxation. You
 should consult your tax adviser to determine whether distributions from the
 Treasury Instruments and Federal Funds (and any other Fund that may hold
 such obligations) derived from interest on such obligations are exempt from
 state income taxation in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Free Money Market and Municipal Money Market Funds pursue their
 investment objectives by limiting their investments to securities issued by
 or on behalf of states, territories, and possessions of the United States
 and their political subdivisions, agencies, authorities and instrumentali-
 ties, and the District of Columbia, the interest from which, if any, is in
 the opinion of bond counsel excluded from gross income for federal income
 tax purposes, and with respect to the Tax-Free Money Market Fund, not an
 item of tax preference under the federal alternative minimum tax. With
 respect to the Municipal Money Market Fund, such interest may not necessar-
 ily be exempt from the federal alternative minimum tax.

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

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

Risks that apply to all Funds:
 
..Money Market Risk--The risk that a Fund will not be able to maintain a NAV
  per share of $1.00 at all times.
..Interest Rate Risk--The risk that during periods of rising interest rates,
  a Fund's yield (and the market value of its securities) will tend to be
  lower than prevailing market rates; in periods of falling interest rates, a
  Fund's yield will tend to be higher.
..Credit/Default Risk--The risk that an issuer or guarantor of a security, or
  a bank or other financial institution that has entered into a repurchase
  agreement, may default on its payment obligations.
..Management Risk--The risk that a strategy used by the Investment Adviser
  may fail to produce the intended results.
..Liquidity Risk--The risk that a Fund will be unable to pay redemption pro-
  ceeds within the time period stated in this Prospectus, because of either
  unusual market conditions, an unusually high volume of redemption requests,
  or other reasons.
..Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by
  the "Year 2000 Problem."
 
Risk that applies to the Government and Federal Funds:
 
..Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market, Premium Money Market, Tax-Free Money
Market and Municipal Money Market Funds:
 
..Concentration Risk--The risk that if a Fund invests more than 25% of its
  total assets in issuers within the same state, industry or economic sector,
  an adverse economic, business or political development may affect the value
  of the Fund's investments more than if its investments were not so concen-
  trated.
..Foreign Risk--The risk that a foreign security (or, in the case of the Tax-
  Free Money Market and Municipal Money Market Funds, a foreign letter of
  credit or guarantee) could lose value as a result of political, financial
  and economic events in foreign countries, less stringent foreign securities
  regulations and accounting and disclosure standards, or other factors. The
  Money Market and Premium Money Market Funds may not invest more than 25% of
  their total assets in the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
Risk that applies to the Money Market and Premium Money Market Funds:
 
..Banking Industry Risk--The risk that if a Fund invests more than 25% of its
  total assets in bank obligations, an adverse development in the banking
  industry may affect the value of the Fund's investments more than if a
  Fund's investments were not invested to such a degree in the banking indus-
  try. Normally, the Money Market and Premium Money Market Funds intend to
  invest more than 25% of their total assets in bank obligations. Banks may
  be particularly susceptible to certain economic factors such as interest
  rate changes, adverse developments in the real estate market, fiscal and
  monetary policy and general economic cycles.
 
Risk that applies to the Tax-Free Money Market and Municipal Money Market
Funds:
 
..Tax Risk--The risk that future legislative or administrative changes or
  court decisions may materially affect the ability of a Fund to pay federal
  tax-exempt dividends.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

Fund Performance
 
 HOW THE FUNDS HAVE PERFORMED
 
 
 The bar chart and table below provide an indication of the risks of invest-
 ing in a Fund by showing: (a) changes in the performance of a Fund's Service
 Shares from year to year; and (b) how the average annual returns of a Fund's
 Service Shares compare to the returns of a composite of mutual funds with
 similar investment objectives. The bar chart and table assume reinvestment
 of dividends and distributions. A Fund's past performance is not necessarily
 an indication of how the Fund will perform in the future. Performance
 reflects expense limitations in effect. If expense limitations were not in
 place, a Fund's performance would have been reduced. You may obtain a Fund's
 current yield by calling 1-800-621-2550. No information has been provided
 for the Municipal Money Market Fund because it has not yet commenced opera-
 tions.

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

Service Organizations may charge other fees directly to their customers who are
the beneficial owners of Administration Shares in connection with their custom-
ers' accounts. You should contact your Service Organization for information
regarding such charges. Such fees may affect the return their customers realize
with respect to their investments.
 
Certain Service Organizations that invest in Service Shares on behalf of their
customers may also receive other compensation in connection with the sale and
distribution of Service Shares or for services to their customers' accounts
and/or the Funds. For additional information regarding such compensation, see

 INVESTMENT ADVISERS
 
 
 
 GSAM, One New York Plaza, New York, New York 10004, a separate operating
 division of Goldman Sachs, acts as investment adviser to the Funds. Goldman
 Sachs registered as an investment adviser in 1981. As of April  , 1999,
 GSAM, together with its affiliates, acted as investment adviser or distribu-
 tor for assets in excess of $  billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
..Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
..Administers each Fund's business affairs
..Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)
 
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter
 into principal transactions in certain taxable money market instruments,
 including repurchase agreements, with Goldman Sachs.
 
 MANAGEMENT FEES
 
 
 As compensation for its services and its assumption of certain expenses, the
 Investment Adviser is entitled to the following fees, computed daily and

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 The Investment Adviser has voluntarily agreed not to impose a portion of its
 management fee and/or to reduce or otherwise limit the daily expenses of
 each Fund (excluding fees payable under service and administration plans for
 certain share classes, taxes, interest, brokerage and litigation, indemnifi-
 cation and other extraordinary expenses). GSAM may discontinue or modify any
 such reductions or limitations in the future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606, also serves as the Funds'
 transfer agent (the "Transfer Agent") and as such performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," which may lead to computer shutdowns or
 errors (commonly known as the "Year 2000 Problem"). To the extent these sys-
 tems conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 computer systems used by the Investment Adviser or other Fund service prov-
 iders do not adequately address this problem in a timely manner.

 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
..The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.
 
                                                                            3-DD

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

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

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

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

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

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

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

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

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

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

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

Dividends
 
 Dividends will be distributed to Service Organizations monthly. Service
 Organizations may choose to have dividends paid in:
..Cash
..Additional shares of the same class of the same Fund
 
 Service Organizations may indicate their election on the Account Applica-
 tion. Any changes may be submitted in writing to Goldman Sachs at any time.
 If a Service Organization does not indicate any choice, dividends and dis-
 tributions will be reinvested automatically in the applicable Fund.
 
 All or substantially all of each Fund's net investment income will be
 declared as a dividend daily. Dividends will normally, but not always, be
 declared as of the following times:

 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and December may be distributed during the
 subsequent calendar year. Although real-
 
                                                                              17

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

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

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

                                                                      APPENDIX A
 
 larly susceptible to certain economic factors, such as interest rate changes
 and adverse developments in the real estate markets. Fiscal and monetary
 policy and general economic cycles can affect the availability and cost of
 funds, loan demand and asset quality and thereby impact the earnings and
 financial conditions of banks.
 
 Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
 asset-backed and receivables-backed securities, whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed and receivables-backed securities are often subject to more
 rapid repayment than their stated maturity date would indicate as a result
 of the pass-through of prepayments of principal on the underlying loans.
 During periods of declining interest rates, prepayment of loans underlying
 asset-backed and receivables-backed securities can be expected to
 accelerate. Accordingly, a Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. In addition, securities that are backed by
 credit card, automobile and similar types of receivables generally do not
 have the benefit of a security interest in collateral that is comparable in
 quality to mortgage assets. There is the possibility that, in some cases,
 recoveries on repossessed collateral may not be available to support
 payments on these securities. In the event of a default, a Fund may suffer a
 loss if it cannot sell collateral quickly and receive the amount it is owed.
 
 Foreign Government Obligations and Related Foreign Risks. Foreign government
 obligations are U.S. dollar-denominated obligations (limited to commercial
 paper and other notes) issued or guaranteed by a foreign government or other
 entity located or organized in a foreign country that maintains a short-term
 foreign currency rating in the highest short-term ratings category by the
 requisite number of NRSROs.
 
 Investments by a Fund in foreign securities, whether issued by a foreign
 government, bank, corporation or other issuer, may present a greater degree
 of risk than investments in securities of domestic issuers because of less
 publicly-available financial and other information, less securities regula-
 tion, potential imposition of foreign withholding and other taxes, war,
 expropriation or other adverse governmental actions. Foreign banks and their
 foreign branches are not regulated by U.S. banking authorities, and gener-
 ally are not bound by the accounting, auditing and financial reporting stan-
 dards applicable to U.S. banks.
 
                                                                            3-FF
<PAGE>
 
 
 
 Repurchase Agreements. Certain Funds may enter into repurchase agreements
 with primary dealers in U.S. Government securities and banks affiliated with
 primary dealers. Repurchase agreements involve the purchase of securities
 subject to the seller's agreement to repurchase them at a mutually agreed
 upon date and price. The repurchase price will exceed the original purchase
 price, the difference being income to the Fund, and will be unrelated to the
 interest rate on the purchased security.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund in connection with the repurchase agree-
 ment are less than the repurchase price and Fund's costs associated with
 delay and enforcement of the repurchase agreement. In addition, in the event
 of bankruptcy of the seller, a Fund could suffer additional losses if a
 court determines that the Fund's interest in the collateral is not enforce-
 able.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.
 
 Municipal Obligations. Municipal obligations are issued by or on behalf of
 states, territories and possessions of the United States and their political
 subdivisions, agencies, authorities and instrumentalities, and the District
 of Columbia. Municipal obligations may include fixed rate notes and similar
 debt instruments; variable and floating rate demand instruments; tax-exempt
 commercial paper; municipal bonds; and unrated notes, paper, bonds or other
 instruments.
 
 Municipal Notes and Bonds. Municipal notes include tax anticipation notes
 ("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
 ("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
 notes. Municipal bonds include general obligation bonds and revenue bonds.
 General obligation bonds are backed by the taxing power of the issuing
 municipality and are considered the safest type of municipal obligation.
 Revenue bonds are backed by the revenues of a project or facility such as
 the tolls from a toll bridge. Revenue bonds also include lease rental reve-
 nue bonds which are issued by a state or local authority for capital pro-
 jects and are secured by annual lease payments from the state or locality
 sufficient to cover debt service on the authority's obliga-

                                                                      APPENDIX A
 
 tions. Industrial development bonds ("private activity bonds") are a spe-
 cific type of revenue bond backed by the credit and security of a private
 user and, therefore, have more potential risk. Municipal bonds may be issued
 in a variety of forms, including commercial paper, tender option bonds and
 variable and floating rate securities.
 
 Tender Option Bonds. A tender option bond is a municipal obligation (gener-
 ally held pursuant to a custodial arrangement) having a relatively long
 maturity and bearing interest at a fixed rate substantially higher than pre-
 vailing short-term, tax-exempt rates. The bond is typically issued in con-
 junction with the agreement of a third party, such as a bank, broker-dealer
 or other financial institution, pursuant to which the institution grants the
 security holder the option, at periodic intervals, to tender its securities
 to the institution. As consideration for providing the option, the financial
 institution receives periodic fees equal to the difference between the
 bond's fixed coupon rate and the rate, as determined by a remarketing or
 similar agent, that would cause the securities, coupled with the tender
 option, to trade at par on the date of such determination. Thus, after pay-
 ment of this fee, the security holder effectively holds a demand obligation
 that bears interest at the prevailing short-term, tax-exempt rate. Certain
 tender option bonds may be illiquid. An institution will normally not be
 obligated to accept tendered bonds in the event of certain defaults or a
 significant downgrading in the credit rating assigned to the issuer of the
 bond. The tender option will be taken into account in determining the matu-
 rity of the tender option bonds and a Fund's average portfolio maturity.
 There is a risk that a Fund will not be considered the owner of a tender
 option bond for federal income tax purposes, and thus will not be entitled
 to treat such interest as exempt from federal income tax.
 
 Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
 issued in anticipation of the issuer's receipt of revenues and present the
 risk that such revenues will be insufficient to satisfy the issuer's payment
 obligations. The entire amount of principal and interest on RAWs is due at
 maturity. RAWs, including those with a maturity of more than 397 days, may
 also be repackaged as instruments which include a demand feature that per-
 mits the holder to sell the RAWs to a bank or other financial institution at
 a purchase price equal to par plus accrued interest on each interest rate
 reset date.
 
 Industrial Development Bonds. Certain Funds may invest in industrial devel-
 opment bonds (private activity bonds), the interest from which would be an
 item of tax preference when distributed by a Fund as "exempt-interest divi-
 dends" to shareholders under the federal alternative minimum tax.
 
 Other Policies. Certain Funds may invest 25% or more of the value of their
 respective total assets in municipal obligations which are related in such a
 way that an
 
                                                                            5-FF

 economic, business or political development or change affecting one munici-
 pal obligation would also affect the other municipal obligation. For exam-
 ple, such Funds may invest all of their respective assets in (a) municipal
 obligations the interest of which is paid solely from revenues from similar
 projects such as hospitals, electric utility systems, multi-family housing,
 nursing homes, commercial facilities (including hotels), steel companies or
 life care facilities, (b) municipal obligations whose issuers are in the
 same state, or (c) industrial development obligations. Concentration of a
 Fund's investments in these municipal obligations will subject the Fund, to
 a greater extent than if such investment was not so concentrated, to the
 risks of adverse economic, business or political developments affecting the
 particular state, industry or other area of concentration.
 
 Municipal obligations may be backed by letters of credit or other forms of
 credit enhancement issued by domestic banks or foreign banks which have a
 branch, agency or subsidiary in the United States or by other financial
 institutions. The credit quality of these banks and financial institutions
 could, therefore, cause a loss to a Fund that invests in municipal obliga-
 tions. Letters of credit and other obligations of foreign banks and finan-
 cial institutions may involve risks in addition to those of domestic obliga-
 tions. See "Foreign Government Obligations and Related Foreign Risks" above.
 In addition, the Funds may acquire securities in the form of custodial
 receipts which evidence ownership of future interest payments, principal
 payments or both on obligations of certain state and local governments and
 authorities.
 
 In order to enhance the liquidity, stability or quality of a municipal obli-
 gation, a Fund may acquire the right to sell the obligation to another party
 at a guaranteed price and date.
 
 Miscellaneous Investments and Policies
 
 Floating and Variable Rate Obligations. The Funds may purchase floating and
 variable rate obligations. The value of these obligations is generally more
 stable than that of a fixed rate obligation in response to changes in inter-
 est rate levels. Subject to the conditions for using amortized cost valua-
 tion under the Investment Company Act, a Fund may consider the maturity of a
 variable or floating rate obligation to be shorter than its ultimate stated
 maturity if the obligation is a U.S. Treasury obligation or U.S. Government
 security, if the obligation has a remaining maturity of 397 calendar days or
 less, or if the obligation has a demand feature that permits the Fund to
 receive payment at any time or at specified intervals not exceeding 397 cal-
 endar days. The issuers or financial intermediaries providing demand fea-
 tures may support their ability to purchase the obligations by obtaining
 credit with liquidity supports. These may include lines of credit, which are
 condi-

 tional commitments to lend and letters of credit, which will ordinarily be
 irrevocable, both of which may be issued by domestic banks or foreign banks
 which have a branch, agency or subsidiary in the United States. A Fund may
 purchase variable or floating rate obligations from the issuers or may pur-
 chase certificates of participation, a type of floating or variable rate
 obligation, which are interests in a pool of debt obligations held by a bank
 or other financial institution.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to a Fund at the time of entering into the transac-
 tion. A forward commitment involves entering into a contract to purchase or
 sell securities for a fixed price at a future date beyond the customary set-
 tlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although a Fund would gener-
 ally purchase securities on a when-issued or forward commitment basis with
 the intention of acquiring the securities for its portfolio, a Fund may dis-
 pose of when-issued securities or forward commitments before settlement
 whenever the Investment Adviser deems it appropriate.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Investment Com-
 pany Act. These limitations include a prohibition on any Fund acquiring more
 than 3% of the voting shares of any other investment company, and a prohibi-
 tion on investing more than 5% of a Fund's total assets in securities of any
 one investment company or more than 10% of its total assets in securities of
 all investment companies. A Fund will indirectly bear its proportionate
 share of any management fees and other expenses paid by such other invest-
 ment companies. Such other investment companies will have investment objec-
 tives, policies and restrictions substantially similar to those of the
 acquiring Fund and will be subject to substantially the same risks.
 
 Illiquid Securities. Each Fund may invest up to 10% of its net assets in
 illiquid securities which cannot be disposed of in seven days in the ordi-
 nary course of business at fair value. Illiquid securities include:
 
  . Both domestic and foreign securities that are not readily marketable
  . Certain municipal leases and participation interests
  . Certain stripped mortgage-backed securities
 
                                                                            7-FF
<PAGE>
 
 
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that a
   restricted security is liquid because it is so-called "4(2) commercial
   paper" or is otherwise eligible for resale pursuant to Rule 144A under the
   Securities Act of 1933.
 
 Investing in restricted securities may decrease the liquidity of a Fund's
 portfolio.
 
 Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from
 banks for temporary or emergency purposes. A Fund may not make additional
 investments if borrowings exceed 5% of its net assets. For more information,
 see the Additional Statement.
 
 Downgraded Securities. After its purchase, a portfolio security may be
 assigned a lower rating or cease to be rated. If this occurs, a Fund may
 continue to hold the security if the Investment Adviser believes it is in
 the best interests of the Fund and its shareholders.

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

 AN INVESTMENT IN A FUND IS NOT A BANK DEPOSIT 
 AND IS NOT INSURED BY THE FEDERAL DEPOSIT 
 INSURANCE CORPORATION OR ANY OTHER GOVERNMENT 
 AGENCY. ALTHOUGH A FUND SEEKS TO PRESERVE THE 
 VALUE OF YOUR INVESTMENT AT $1.00 PER SHARE, 
 IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN A 
 FUND.

General Investment Management Approach
 
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Investment adviser to the
 Funds. Goldman Sachs Asset Management is referred to in this Prospectus as
 the "Investment Adviser."
 
 Goldman Sachs' Money Market Investment Philosophy
 The Money Market Funds are managed to seek maximum current income consistent
 with the preservation of capital and daily liquidity. In managing the Funds,
 the Investment Adviser follows a conservative, risk-managed investment proc-
 ess that seeks to:
..Manage credit risk
..Manage interest rate risk
..Manage liquidity
 
 The Investment Adviser actively manages the Goldman Sachs Money Market Funds
 in designing and structuring the Funds' investment portfolios.
 
- --------------------------------------------------------------------------------
 
 
 Investment Process
 The Investment Adviser follows a consistent five-step investment process
 across all of its money market portfolios.
 
 1. Define investment objectives and risk parameters
 The Investment Adviser works closely within Fund and Rule 2a-7 guidelines in
 seeking to meet investment objectives for each Fund.
 
 2. Establish benchmarks
 Benchmarks are the IBC Financial Data Universal Averages. Depending upon the
 eligible investments of each Fund, there is a corresponding IBC Index.
 
 3. Establish a risk-managed framework
 Understanding and managing risk is critical to the performance of money mar-
 ket fund portfolios.
 
                                                                            1-CC
<PAGE>
 
 
 
 4. Actively manage the portfolios
 General portfolio strategy meetings are held weekly.
 
 5. Monitor Risk Exposure
 Risk reports enable the Investment Adviser to monitor portfolios on a daily
 basis and track all trading activity.
 
 
.. The Funds: Each Fund's securities are valued by the amortized cost method
   as permitted under Rule 2a-7 of the Investment Company Act of 1940, as
   amended (the "1940 Act"). Under Rule 2a-7, each Fund may invest only in
   U.S. dollar-denominated securities that are determined to present minimal
   credit risk and meet certain other criteria including, conditions relating
   to maturity, diversification and credit quality. These operating policies
   may be more restrictive than the fundamental policies set forth in the
   Statement of Additional Information (the "Additional Statement").
  .   Taxable Funds: Prime Obligations, Money Market, Premium Money Market,
      Treasury Obligations and Government Funds.
  .   Tax-Advantaged Funds: Treasury Instruments and Federal Funds.
  .   Tax-Exempt Funds: Tax-Free Money Market and Municipal Money Market
      Funds.
.. The Investors: The Funds are designed for institutional investors seeking
   a high rate of return, a stable net asset value ("NAV") and convenient
   liquidation privileges. The Funds are particularly suitable for banks,
   corporations and other financial institutions that seek investment of
   short-term funds for their own accounts or for the accounts of their cus-
   tomers. Shares of the Government Fund are intended to qualify as eligible
   investments for federally chartered credit unions pursuant to Sections
   107(7), 107(8) and 107(15) of the Federal Credit Union Act, Part 703 of
   the National Credit Union Administration ("NCUA") Rules and Regulations
   and NCUA Letter Number 155. The Fund intends to review changes in the
   applicable laws, rules and regulations governing eligible investments for
   federally chartered credit unions, and to take such action as may be nec-
   essary so that the investments of the Fund qualify as eligible investments
   under the Federal Credit Union Act and the regulations thereunder. Shares
   of the Government Fund, however, may or may not qualify as eligible
   investments for particular state-chartered credit unions. A state-chart-
   ered credit union should consult qualified legal counsel to determine
   whether the Government Fund is a permissible investment under the law
   applicable to it.

   mined pursuant to Rule 2a-7) at the time of purchase.
..  Dollar-Weighted Average Portfolio Maturity ("WAM"): Not more than 90 days
   (as required by Rule 2a-7).
..  Investment Restrictions: Each Fund is subject to certain investment
   restrictions that are described in detail under "Investment Restrictions" in
   the Additional Statement. Fundamental investment restrictions and the
   investment objective of a Fund cannot be changed without approval of a
   majority of the outstanding shares of that Fund. The Treasury Obligations
   Fund's policy of limiting its investments to U.S. Treasury obligations and
   related repurchase agreements is also fundamental. All investment policies
   not specifically designated as fundamental are non-fundamental and may be
   changed without shareholder approval.
..  Diversification. Diversification can help a Fund reduce the risks of
   investing. In accordance with current regulations of the Securities and
   Exchange Commission (the "SEC"), each Fund may not invest more than 5% of the
   value of its total assets at the time of purchase in the securities of any
   single issuer. However, a Fund may invest up to 25% of the value of the total
   assets in the securities of a single issuer for up to three business days.
   These limitations do not apply to cash, certain repurchase agree-ments, U.S.
   Government securities or securities of other investment compa-nies. In
   addition, securities subject to certain unconditional guarantees and
   securities that are not "First Tier Securities" as defined by the SEC are
   subject to different diversification requirements as described in the
   Additional Statement.
                                                                            3-CC

 Fund Investment Objectives and Strategies
 
 
 INVESTMENT OBJECTIVES
 
 
 Taxable and Tax-Advantaged Funds:
 
 The Prime Obligations, Money Market, Premium Money Market, Treasury Obliga-
 tions, Treasury Instruments, Government, Federal, Tax-Free Money Market and
 Municipal Money Market Funds seek to maximize current income to the extent
 consistent with the preservation of capital and the maintenance of liquidity
 by investing exclusively in high quality money market instruments.
 
 In order to obtain a rating from a rating organization, the Premium Money
 Market Fund will observe special investment restrictions.
 
 The Treasury Instruments and Federal Funds pursue their investment objec-
 tives by limiting their investments to certain U.S. Treasury obligations and
 U.S. Government securities (each as defined in Appendix A), respectively,
 the interest from which is generally exempt from state income taxation. You
 should consult your tax adviser to determine whether distributions from the
 Treasury Instruments and Federal Funds (and any other Fund that may hold
 such obligations) derived from interest on such obligations are exempt from
 state income taxation in your own state.
 
 Tax-Exempt Funds:
 
 The Tax-Free Money Market and Municipal Money Market Funds pursue their
 investment objectives by limiting their investments to securities issued by
 or on behalf of states, territories, and possessions of the United States
 and their political subdivisions, agencies, authorities and instrumentali-
 ties, and the District of Columbia, the interest from which, if any, is in
 the opinion of bond counsel excluded from gross income for federal income
 tax purposes, and with respect to the Tax-Free Money Market Fund, not an
 item of tax preference under the federal alternative minimum tax. With
 respect to the Municipal Money Market Fund, such interest may not necessar-
 ily be exempt from the federal alternative minimum tax.

 Note: See Appendix A for a description of, and certain criteria applicable
 to, each of these categories of investments.
 /1/If adverse economic conditions prevail in the banking industry (such as
   substantial losses on loans, increases in non-performing assets and charge-
   offs and declines in total deposits) the Funds may, for temporary defensive
   purposes, invest less than 25% of their total assets in bank obligations.
 /2/To the extent required by Rule 2a-7, asset-backed and receivables-backed
   securities will be rated by the requisite number of nationally recognized
   statistical rating organizations ("NRSROs").
 /3/U.S. Treasury obligations are securities issued by the U.S. Treasury.
 /4/U.S. Treasury Obligations are securities issued or guaranteed by the U.S.
   Treasury.

 /6/Ordinarily expect that 100% of a Fund's portfolio securities will be
   invested in municipal obligations, but the Funds may, for temporary

 /7/To the extent permitted by Rule 2a-7, securities without short-term

   First Tier Securities, or to the extent that a Fund may purchase Second
   Tier Securities, comparable in quality to Second Tier Securities. In
   addition, a Fund holding a security supported by a guarantee or demand

   in determining the credit quality of the investment.

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

Risks that apply to all Funds:
 
..Money Market Risk--The risk that a Fund will not be able to maintain a NAV
  per share of $1.00 at all times.
..Interest Rate Risk--The risk that during periods of rising interest rates,
  a Fund's yield (and the market value of its securities) will tend to be
  lower than prevailing market rates; in periods of falling interest rates, a
  Fund's yield will tend to be higher.
..Credit/Default Risk--The risk that an issuer or guarantor of a security, or
  a bank or other financial institution that has entered into a repurchase
  agreement, may default on its payment obligations.
..Management Risk--The risk that a strategy used by the Investment Adviser
  may fail to produce the intended results.
..Liquidity Risk--The risk that a Fund will be unable to pay redemption pro-
  ceeds within the time period stated in this Prospectus, because of either
  unusual market conditions, an unusually high volume of redemption requests,
  or other reasons.
..Other Risks--Each Fund is subject to other risks, such as the risk that its
  operations, or the value of its portfolio securities, will be disrupted by
  the "Year 2000 Problem."
 
Risk that applies to the Government and Federal Funds:
 
..Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risks that apply to the Money Market, Premium Money Market, Tax-Free Money
Market and Municipal Money Market Funds:
 
..Concentration Risk--The risk that if a Fund invests more than 25% of its
  total assets in issuers within the same state, industry or economic sector,
  an adverse economic, business or political development may affect the value
  of the Fund's investments more than if its investments were not so concen-
  trated.
..Foreign Risk--The risk that a foreign security (or, in the case of the Tax-
  Free Money Market and Municipal Money Market Funds, a foreign letter of
  credit or guarantee) could lose value as a result of political, financial
  and economic events in foreign countries, less stringent foreign securities
  regulations and accounting and disclosure standards, or other factors. The
  Money Market and Premium Money Market Funds may not invest more than 25% of
  their total assets in the securities of any one foreign government.

                                                    PRINCIPAL RISKS OF THE FUNDS
 
 
Risk that applies to the Money Market and Premium Money Market Funds:
 
..Banking Industry Risk--The risk that if a Fund invests more than 25% of its
  total assets in bank obligations, an adverse development in the banking
  industry may affect the value of the Fund's investments more than if a
  Fund's investments were not invested to such a degree in the banking indus-
  try. Normally, the Money Market and Premium Money Market Funds intend to
  invest more than 25% of their total assets in bank obligations. Banks may
  be particularly susceptible to certain economic factors such as interest
  rate changes, adverse developments in the real estate market, fiscal and
  monetary policy and general economic cycles.
 
Risk that applies to the Tax-Free Money Market and Municipal Money Market
Funds:
 
..Tax Risk--The risk that future legislative or administrative changes or
  court decisions may materially affect the ability of a Fund to pay federal
  tax-exempt dividends.
 
More information about the Funds' portfolio securities and investment tech-
niques, and their associated risks, is provided in Appendix A. You should con-
sider the investment risks discussed in this section and in Appendix A. Both
are important to your investment choice.

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

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

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

 tor for assets in excess of $  billion.
 
 The Investment Adviser provides day-to-day advice regarding the Funds' port-
 folio transactions. The Investment Adviser also performs the following serv-
 ices for the Funds:
..Continually manages each Fund, including the purchase, retention and dispo-
  sition of securities and other assets
..Administers each Fund's business affairs
..Performs various recordholder servicing functions (to the extent not pro-
  vided by other organizations)
 
 Pursuant to an SEC order, each Taxable and Tax-Advantaged Fund may enter

 The difference, if any, between the stated fees and the actual fees paid by
 the Funds reflects that the Investment Adviser did not charge the full
 amount of the fees to which it would have been entitled. The Investment
 Adviser may discontinue or modify any such voluntary limitations in the
 future at its discretion.
 
 The Investment Adviser has voluntarily agreed not to impose a portion of its
 management fee and/or to reduce or otherwise limit the daily expenses of
 each Fund (excluding fees payable under service and administration plans for
 certain share classes, taxes, interest, brokerage and litigation, indemnifi-
 cation and other extraordinary expenses). GSAM may discontinue or modify any
 such reductions or limitations in the future at its discretion.
 
 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois 60606, also serves as the Funds'
 transfer agent (the "Transfer Agent") and as such performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Funds. Goldman Sachs reserves the right to redeem at any
 time some or all of the shares acquired for its own account.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather than the year "2000," which may lead to computer shutdowns or
 errors (commonly known as the "Year 2000 Problem"). To the extent these sys-
 tems conduct forward-looking calculations, these computer problems may occur
 prior to January 1, 2000. Like other investment companies and financial and
 business organizations, the Funds could be adversely affected in their abil-
 ity to process securities trades, price securities, provide shareholder
 account services and otherwise conduct normal business operations if the
 computer systems used by the Investment Adviser or other Fund service prov-
 iders do not adequately address this problem in a timely manner.

 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
..The Investment Adviser has sought assurances from the Funds' other service
  providers that they are taking the steps necessary so that they do not
  experience Year 2000 Problems, and the Investment Adviser will continue to
  monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Funds at current levels.
 
 In addition, Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Funds. The Investment Adviser
 may obtain such Year 2000 information from various sources which the Invest-
 ment Adviser believes to be reliable, including the issuers' public regula-
 tory filings. However, the Investment Adviser is not in a position to verify
 the accuracy or completeness of such information.

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

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

                   (8:00 a.m. to 4:00 p.m. New York time)
 --------------------------------------------------------
</TABLE>
 Before or immediately after placing an initial purchase order, a Service
 Organization should complete and send to Goldman Sachs the Account Applica-
 tion. Subsequent purchase orders should be accompanied by information iden-
 tifying the account and the Fund in which Preferred Shares are to be pur-
 chased.
 
 Service Organizations may send their payments as follows:
..Wire federal funds to The Northern Trust Company ("Northern"), as sub- cus-
  todian for State Street Bank and Trust Company ("State Street") (each
  Fund's custodian); or
 
                                                                            1-HH
<PAGE>
 
 
..Initiate an Automated Clearing House Network ("ACH") transfer to Goldman
  Sachs Trust (the "Trust") c/o Northern, as sub-custodian for State Street;
  or
..Send a check or Federal Reserve draft payable to Goldman Sachs Funds --
  (Name of Fund and Class of Shares), 4900 Sears Tower -- 60th Floor, Chica-
  go, IL. 60606-6372. The Trust will not accept a check drawn on a foreign
  bank or a third-party check.
 
 It is strongly recommended that payment be effected by wiring federal funds
 to Northern.
 
 It is expected that Federal Reserve drafts will ordinarily be converted to
 federal funds on the day of receipt and that checks will be converted to
 federal funds within two business days after receipt. ACH transfers are
 expected to convert to federal funds on the business day following receipt
 of the ACH transfer.

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

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

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

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

 To help each Fund maintain its $1.00 constant share price, portfolio securi-
 ties are valued at amortized cost in accordance with SEC regulations. Amor-
 tized cost will normally approximate market value. There can be no assurance
 that a Fund will be able at all times to maintain a NAV of $1.00 per share.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Preferred Shares Of The Funds?
 Generally, Preferred Shares may be sold (redeemed) only through Service
 Organizations. Customers of a Service Organization will normally give their
 redemption instructions to the Service Organization, and the Service Organi-
 zation will, in turn, place redemption orders with the Funds. Generally,
 each Fund will redeem Preferred Shares upon request on any business day at
 their NAV next determined after receipt of such request in proper form.
 
 A Service Organization may request redemptions in writing or by telephone if
 the optional telephone redemption privilege is elected on the Account Appli-
 cation.

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

..Although redemption proceeds will normally be wired as described above,
  each Fund reserves the right to pay redemption proceeds up to three busi-
  ness days following receipt of a properly executed wire transfer redemption
  request. If you are selling shares you recently paid for by check, the Fund
  will pay you when your check has cleared which may take up to 15 days. If

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

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

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

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

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

 Dividends will be reinvested as of the last calendar day of each month. Cash
 distributions normally will be paid on or about the first business day of
 each month. Net short-term capital gains, if any, will be distributed in
 accordance with federal income tax requirements and may be reflected in a
 Fund's daily distributions.
 
 Each Fund may distribute at least annually other realized capital gains, if
 any, after reduction by available capital losses. In order to avoid exces-
 sive fluctuations in the amount of monthly capital gains distributions, a
 portion of any net capital gains realized on the disposition of securities
 during the months of November and
 
                                                                              17

 December may be distributed during the subsequent calendar year. Although
 realized gains and losses on the assets of a Fund are reflected in the NAV
 of the Fund, they are not expected to be of an amount which would affect the
 Fund's NAV of $1.00 per share.
 
 The income declared as a dividend for the Treasury Obligations, Government
 and Premium Money Market Funds is based on estimates of net investment
 income for each Fund. Actual income may differ from estimates, and differ-
 ences, if any, will be included in the calculation of subsequent dividends.

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

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

                                                                      APPENDIX A
 
 larly susceptible to certain economic factors, such as interest rate changes
 and adverse developments in the real estate markets. Fiscal and monetary
 policy and general economic cycles can affect the availability and cost of
 funds, loan demand and asset quality and thereby impact the earnings and
 financial conditions of banks.
 
 Asset-Backed and Receivables-Backed Securities. Certain Funds may invest in
 asset-backed and receivables-backed securities, whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed and receivables-backed securities are often subject to more
 rapid repayment than their stated maturity date would indicate as a result
 of the pass-through of prepayments of principal on the underlying loans.
 During periods of declining interest rates, prepayment of loans underlying
 asset-backed and receivables-backed securities can be expected to
 accelerate. Accordingly, a Fund's ability to maintain positions in such
 securities will be affected by reductions in the principal amount of such
 securities resulting from prepayments, and its ability to reinvest the
 returns of principal at comparable yields is subject to generally prevailing
 interest rates at that time. In addition, securities that are backed by
 credit card, automobile and similar types of receivables generally do not
 have the benefit of a security interest in collateral that is comparable in
 quality to mortgage assets. There is the possibility that, in some cases,
 recoveries on repossessed collateral may not be available to support
 payments on these securities. In the event of a default, a Fund may suffer a
 loss if it cannot sell collateral quickly and receive the amount it is owed.
 
 Foreign Government Obligations and Related Foreign Risks. Foreign government
 obligations are U.S. dollar-denominated obligations (limited to commercial
 paper and other notes) issued or guaranteed by a foreign government or other
 entity located or organized in a foreign country that maintains a short-term
 foreign currency rating in the highest short-term ratings category by the
 requisite number of NRSROs.
 
 Investments by a Fund in foreign securities, whether issued by a foreign
 government, bank, corporation or other issuer, may present a greater degree
 of risk than investments in securities of domestic issuers because of less
 publicly-available financial and other information, less securities regula-
 tion, potential imposition of foreign withholding and other taxes, war,
 expropriation or other adverse governmental actions. Foreign banks and their
 foreign branches are not regulated by U.S. banking authorities, and gener-
 ally are not bound by the accounting, auditing and financial reporting stan-
 dards applicable to U.S. banks.
 
                                                                            3-FF
<PAGE>
 
 
 
 Repurchase Agreements. Certain Funds may enter into repurchase agreements
 with primary dealers in U.S. Government securities and banks affiliated with
 primary dealers. Repurchase agreements involve the purchase of securities
 subject to the seller's agreement to repurchase them at a mutually agreed
 upon date and price. The repurchase price will exceed the original purchase
 price, the difference being income to the Fund, and will be unrelated to the
 interest rate on the purchased security.
 
 If the other party or "seller" defaults, a Fund might suffer a loss to the
 extent that the proceeds from the sale of the underlying securities and
 other collateral held by the Fund in connection with the repurchase agree-
 ment are less than the repurchase price and Fund's costs associated with
 delay and enforcement of the repurchase agreement. In addition, in the event
 of bankruptcy of the seller, a Fund could suffer additional losses if a
 court determines that the Fund's interest in the collateral is not enforce-
 able.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to a Fund's
 shareholders. In addition, certain Funds, together with other registered
 investment companies having advisory agreements with the Investment Adviser
 or any of its affiliates, may transfer uninvested cash balances into a sin-
 gle joint account, the daily aggregate balance of which will be invested in
 one or more repurchase agreements.
 
 Municipal Obligations. Municipal obligations are issued by or on behalf of
 states, territories and possessions of the United States and their political
 subdivisions, agencies, authorities and instrumentalities, and the District
 of Columbia. Municipal obligations may include fixed rate notes and similar
 debt instruments; variable and floating rate demand instruments; tax-exempt
 commercial paper; municipal bonds; and unrated notes, paper, bonds or other
 instruments.
 
 Municipal Notes and Bonds. Municipal notes include tax anticipation notes
 ("TANs"), revenue anticipation notes ("RANs"), bond anticipation notes
 ("BANs"), tax and revenue anticipation notes ("TRANs") and construction loan
 notes. Municipal bonds include general obligation bonds and revenue bonds.
 General obligation bonds are backed by the taxing power of the issuing
 municipality and are considered the safest type of municipal obligation.
 Revenue bonds are backed by the revenues of a project or facility such as
 the tolls from a toll bridge. Revenue bonds also include lease rental reve-
 nue bonds which are issued by a state or local authority for capital pro-
 jects and are secured by annual lease payments from the state or locality
 sufficient to cover debt service on the authority's obliga-

                                                                      APPENDIX A
 
 tions. Industrial development bonds ("private activity bonds") are a spe-
 cific type of revenue bond backed by the credit and security of a private
 user and, therefore, have more potential risk. Municipal bonds may be issued
 in a variety of forms, including commercial paper, tender option bonds and
 variable and floating rate securities.
 
 Tender Option Bonds. A tender option bond is a municipal obligation (gener-
 ally held pursuant to a custodial arrangement) having a relatively long
 maturity and bearing interest at a fixed rate substantially higher than pre-
 vailing short-term, tax-exempt rates. The bond is typically issued in con-
 junction with the agreement of a third party, such as a bank, broker-dealer
 or other financial institution, pursuant to which the institution grants the
 security holder the option, at periodic intervals, to tender its securities
 to the institution. As consideration for providing the option, the financial
 institution receives periodic fees equal to the difference between the
 bond's fixed coupon rate and the rate, as determined by a remarketing or
 similar agent, that would cause the securities, coupled with the tender
 option, to trade at par on the date of such determination. Thus, after pay-
 ment of this fee, the security holder effectively holds a demand obligation
 that bears interest at the prevailing short-term, tax-exempt rate. Certain
 tender option bonds may be illiquid. An institution will normally not be
 obligated to accept tendered bonds in the event of certain defaults or a
 significant downgrading in the credit rating assigned to the issuer of the
 bond. The tender option will be taken into account in determining the matu-
 rity of the tender option bonds and a Fund's average portfolio maturity.
 There is a risk that a Fund will not be considered the owner of a tender
 option bond for federal income tax purposes, and thus will not be entitled
 to treat such interest as exempt from federal income tax.
 
 Revenue Anticipation Warrants. Revenue Anticipation Warrants ("RAWs") are
 issued in anticipation of the issuer's receipt of revenues and present the
 risk that such revenues will be insufficient to satisfy the issuer's payment
 obligations. The entire amount of principal and interest on RAWs is due at
 maturity. RAWs, including those with a maturity of more than 397 days, may
 also be repackaged as instruments which include a demand feature that per-
 mits the holder to sell the RAWs to a bank or other financial institution at
 a purchase price equal to par plus accrued interest on each interest rate
 reset date.
 
 Industrial Development Bonds. Certain Funds may invest in industrial devel-
 opment bonds (private activity bonds), the interest from which would be an
 item of tax preference when distributed by a Fund as "exempt-interest divi-
 dends" to shareholders under the federal alternative minimum tax.
 
 Other Policies. Certain Funds may invest 25% or more of the value of their
 respective total assets in municipal obligations which are related in such a
 way that an
 
                                                                            5-FF
<PAGE>
 
 
 economic, business or political development or change affecting one munici-
 pal obligation would also affect the other municipal obligation. For exam-
 ple, such Funds may invest all of their respective assets in (a) municipal
 obligations the interest of which is paid solely from revenues from similar
 projects such as hospitals, electric utility systems, multi-family housing,
 nursing homes, commercial facilities (including hotels), steel companies or
 life care facilities, (b) municipal obligations whose issuers are in the
 same state, or (c) industrial development obligations. Concentration of a
 Fund's investments in these municipal obligations will subject the Fund, to
 a greater extent than if such investment was not so concentrated, to the
 risks of adverse economic, business or political developments affecting the
 particular state, industry or other area of concentration.
 
 Municipal obligations may be backed by letters of credit or other forms of
 credit enhancement issued by domestic banks or foreign banks which have a
 branch, agency or subsidiary in the United States or by other financial
 institutions. The credit quality of these banks and financial institutions
 could, therefore, cause a loss to a Fund that invests in municipal obliga-
 tions. Letters of credit and other obligations of foreign banks and finan-
 cial institutions may involve risks in addition to those of domestic obliga-
 tions. See "Foreign Government Obligations and Related Foreign Risks" above.
 In addition, the Funds may acquire securities in the form of custodial
 receipts which evidence ownership of future interest payments, principal
 payments or both on obligations of certain state and local governments and
 authorities.
 
 In order to enhance the liquidity, stability or quality of a municipal obli-
 gation, a Fund may acquire the right to sell the obligation to another party
 at a guaranteed price and date.
 
 Miscellaneous Investments and Policies
 
 Floating and Variable Rate Obligations. The Funds may purchase floating and
 variable rate obligations. The value of these obligations is generally more
 stable than that of a fixed rate obligation in response to changes in inter-
 est rate levels. Subject to the conditions for using amortized cost valua-
 tion under the Investment Company Act, a Fund may consider the maturity of a
 variable or floating rate obligation to be shorter than its ultimate stated
 maturity if the obligation is a U.S. Treasury obligation or U.S. Government
 security, if the obligation has a remaining maturity of 397 calendar days or
 less, or if the obligation has a demand feature that permits the Fund to
 receive payment at any time or at specified intervals not exceeding 397 cal-
 endar days. The issuers or financial intermediaries providing demand fea-
 tures may support their ability to purchase the obligations by obtaining
 credit with liquidity supports. These may include lines of credit, which are
 condi-

                                                                      APPENDIX A
 
 tional commitments to lend and letters of credit, which will ordinarily be
 irrevocable, both of which may be issued by domestic banks or foreign banks
 which have a branch, agency or subsidiary in the United States. A Fund may
 purchase variable or floating rate obligations from the issuers or may pur-
 chase certificates of participation, a type of floating or variable rate
 obligation, which are interests in a pool of debt obligations held by a bank
 or other financial institution.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to a Fund at the time of entering into the transac-
 tion. A forward commitment involves entering into a contract to purchase or
 sell securities for a fixed price at a future date beyond the customary set-
 tlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although a Fund would gener-
 ally purchase securities on a when-issued or forward commitment basis with
 the intention of acquiring the securities for its portfolio, a Fund may dis-
 pose of when-issued securities or forward commitments before settlement
 whenever the Investment Adviser deems it appropriate.
 
 Other Investment Companies. A Fund may invest in securities of other invest-
 ment companies subject to the limitations prescribed by the Investment Com-
 pany Act. These limitations include a prohibition on any Fund acquiring more
 than 3% of the voting shares of any other investment company, and a prohibi-
 tion on investing more than 5% of a Fund's total assets in securities of any
 one investment company or more than 10% of its total assets in securities of
 all investment companies. A Fund will indirectly bear its proportionate
 share of any management fees and other expenses paid by such other invest-
 ment companies. Such other investment companies will have investment objec-
 tives, policies and restrictions substantially similar to those of the
 acquiring Fund and will be subject to substantially the same risks.
 
 Illiquid Securities. Each Fund may invest up to 10% of its net assets in
 illiquid securities which cannot be disposed of in seven days in the ordi-
 nary course of business at fair value. Illiquid securities include:
 
  . Both domestic and foreign securities that are not readily marketable
  . Certain municipal leases and participation interests
  . Certain stripped mortgage-backed securities
 
                                                                            7-FF
<PAGE>
 
 
  .Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  .Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that a
   restricted security is liquid because it is so-called "4(2) commercial
   paper" or is otherwise eligible for resale pursuant to Rule 144A under the
   Securities Act of 1933.
 
 Investing in restricted securities may decrease the liquidity of a Fund's
 portfolio.
 
 Borrowings. Each Fund may borrow up to 33 1/3% of its total assets from
 banks for temporary or emergency purposes. A Fund may not make additional
 investments if borrowings exceed 5% of its net assets. For more information,
 see the Additional Statement.
 
 Downgraded Securities. After its purchase, a portfolio security may be
 assigned a lower rating or cease to be rated. If this occurs, a Fund may
 continue to hold the security if the Investment Adviser believes it is in
 the best interests of the Fund and its shareholders.

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

General Investment
Management Approach
 
Goldman Sachs Asset Management, a separate operating division of Goldman, Sachs
& Co. ("Goldman Sachs"), serves as investment adviser (the "Investment Advis-
er") to five asset allocation portfolios: the Conservative Strategy Portfolio,
Balanced Strategy Portfolio (formerly, the Income Strategy Portfolio), Growth
and Income Strategy Portfolio, Growth Strategy Portfolio and Aggressive Growth
Strategy Portfolio (referred to as the "Portfolios" or the "Funds" interchange-
ably herein). The Portfolios are intended for investors who prefer to have
their asset allocation decisions made by professional money managers. Each
Portfolio seeks to achieve its objectives by investing in a combination of
underlying funds for which Goldman Sachs now or in the future acts as invest-
ment adviser or principal underwriter (the "Underlying Funds"). Some of these
Funds invest primarily in fixed-income or money market securities (the "Under-
lying Fixed-Income Funds"); other Funds invest primarily in equity securities
(the "Underlying Equity Funds"). You may choose to invest in one or more of the
Portfolios based on your personal investment goals, risk tolerance, and finan-
cial circumstances.
 
Goldman Sachs' Asset Allocation Investment Philosophy
The Investment Adviser's Quantitative Research Group uses disciplined quantita-
tive models to determine the relative attractiveness of the world's stock, bond
and currency markets. These models use financial and economic variables to cap-
ture fundamental relationships that it believes make sense. While the Invest-
ment Adviser's process is rigorous and quantitative, it also incorporates clear
economic reasoning behind each recommendation.
 
Each Portfolio starts with a "base-line" or strategic allocation among the var-
ious asset classes. The Investment Adviser then tactically deviates from the
strategic allocations based on forecasts provided by the models. The tactical
process seeks to add value by overweighing attractive markets and underweighing
unattractive markets. Greater deviations from the strategic allocation of a
given Portfolio result in higher risk that the tactical allocation will
underperform the strategic allocation. However, the Investment Adviser's risk
control process balances the amount any asset class can be overweighed in seek-
ing to achieve higher expected returns
 
 The Asset Allocation Investment Philosophy involves investing a Portfolio's
 assets in other Goldman Sachs Funds within specified equity and fixed-income
 percentage ranges.

 against the amount of risk imposed by that deviation from the strategic
 allocation. The Investment Adviser employs Goldman Sachs' proprietary Black-
 Litterman asset allocation technique in an effort to optimally balance these
 two goals. This technique combines the Quantitative Research Group's market
 forecast with economic equilibrium in seeking to construct risk-controlled
 portfolios.

Portfolio Investment Objectives and Strategies
 
 Goldman Sachs Conservative Strategy Portfolio
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income, consistent with the preservation of cap-
 ital and secondarily also considers the potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 80% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds, with a focus on
 short-term investments including money market funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its assets in
 the Global Income Fund, Financial Square Prime Obligations Fund and CORE
 Large Cap Value Fund. It is expected that the Portfolio will invest more
 than 25% of its assets in the Short Duration Government Fund. The Portfolio
 may not invest in International Underlying Equity Funds.

<PAGE>
 
Goldman Sachs Balanced Strategy Portfolio
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income and long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 60% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its equity
 allocation in the CORE Large Cap Growth, CORE Large Cap Value and CORE
 International Equity Funds and will invest a relatively significant percent-
 age of its assets in the Global Income Fund. It is expected that the Portfo-
 lio will invest more than 25% of its assets in the Short Duration Government
 Fund.

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

 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks long-term capital appreciation and secondarily current
 income.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 80% of the Portfolio's total assets
 will be allocated among Underlying Equity Funds, with a blend of domestic
 large cap, small cap and international exposure to seek capital apprecia-
 tion. Allocation to Underlying Fixed-Income Funds is intended to provide
 diversification. The Investment Adviser expects that the Portfolio will
 invest a relatively significant percentage of its equity allocation in the
 CORE Large Cap Growth, CORE Large Cap Value and CORE International Equity
 Funds.

Goldman Sachs Aggressive Growth Strategy Portfolio
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, substantially all of the Portfolio's total assets
 will be allocated among Underlying Equity Funds, with a greater focus on
 small cap and international investments. The Investment Adviser expects that
 the Portfolio will invest a relatively significant percentage of its assets
 in the CORE Large Cap Growth, CORE Large Cap Value and CORE International
 Equity Funds.

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

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

                                                 PRINCIPAL INVESTMENT STRATEGIES
 
 
 While each Portfolio can invest in any or all of the Underlying Funds, it is
 expected that each Portfolio will normally invest in only some of the Under-
 lying Funds at any particular time. Each Portfolio's investment in any of
 the Underlying Funds may, and in some cases is expected to, exceed 25% of
 such Portfolio's total assets.
 
 THE PARTICULAR UNDERLYING FUNDS IN WHICH EACH PORTFOLIO MAY INVEST, THE
 EQUITY/FIXED INCOME TARGETS AND RANGES AND THE INVESTMENTS IN EACH UNDER-
 LYING FUND MAY BE CHANGED FROM TIME TO TIME WITHOUT SHAREHOLDER APPROVAL.

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

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

Description of the Underlying Funds
 
 DESCRIPTION OF THE UNDERLYING FUNDS
 
 The following is a concise description of the investment objectives and
 practices for each of the Underlying Funds that are available for investment
 by the Portfolios as of the date of this Prospectus. A Portfolio may also
 invest in other Underlying Funds not listed below that may become available
 for investment in the future at the discretion of the Investment Adviser
 without shareholder approval. Additional information regarding the invest-

Principal Risks of the Underlying Funds
 
The following summarizes important risks that apply to the Underlying Funds and
may result in a loss of your investment in a Portfolio. There can be no assur-
ance that an Underlying Fund will achieve its investment objective.
 
Risks That Apply To All Underlying Funds:
 
 ^Market Risk--The risk that the value of the securities in which an Under-
  lying Fund invests may go up or down in response to the prospects of indi-
  vidual companies and/or general economic conditions. Price changes may be
  temporary or last for extended periods.
 ^Derivatives Risk--The risk that loss may result from an Underlying Fund's
  investments in options, futures, swaps, structured securities and other
  derivative instruments, which may be leveraged.
 ^Management Risk--The risk that a strategy used by an investment adviser to
  the Underlying Funds may fail to produce the intended results.
 ^Liquidity Risk--The risk that an Underlying Fund will not be able to pay
  redemption proceeds within the time period stated in this Prospectus,
  because of unusual market conditions, an unusually high volume of redemp-
  tion requests, or other reasons. Funds that invest in small capitalization
  stocks, REITs and emerging country issuers will be especially subject to
  the risk that during certain periods the liquidity of particular issuers or
  industries, or all securities within these investment categories, will
  shrink or disappear suddenly and without warning as a result of adverse
  economic, market or political events, or adverse investor perceptions,
  whether or not accurate.
 ^Other Risks--Each Underlying Fund is subject to other risks, such as the
  risk that its operations, or the value of its portfolio securities, will be
  disrupted by the "Year 2000 Problem."
 
Risks That Apply Primarily To The Underlying Fixed-Income Funds:
 
 ^Interest Rate Risk--The risk that when interest rates increase, fixed-
  income securities held by an Underlying Fund will decline in value. Long-
  term fixed-income securities will normally have more price volatility
  because of this risk than short-term securities.
 ^Credit/Default Risk--The risk that an issuer of fixed-income securities
  held by an Underlying Fund (which may have low credit ratings) may default
  on its obligation to pay interest and repay principal.
 ^Call Risk--The risk that an issuer will exercise its right to pay principal
  on an obligation held by an Underlying Fund (such as a mortgage-backed secu-
 
                                                                            17-Z

  rity) earlier than expected. This may happen when there is a decline in
  interest rates. Under these circumstances, an Underlying Fund may be unable
  to recoup all of its initial investment and will also suffer from having to
  reinvest in lower yielding securities.
 ^Extension Risk--The risk that an issuer will exercise its right to pay
  principal on an obligation held by an Underlying Fund (such as a mortgage-
  backed security) later than expected. This may happen when there is a rise
  in interest rates. Under these circumstances, the value of an obligation
  will decrease, and an Underlying Fund will also suffer from the inability
  to invest in higher yielding securities.
 ^Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risk That Applies Primarily To The Underlying Equity Funds:
 
 ^Stock Risk--The risk that stock prices have historically risen and fallen
  in periodic cycles. As of the date of this Prospectus, U.S. stock markets
  and certain foreign stock markets were trading at or close to record high
  levels. There is no guarantee that such levels will continue.
 
Risks That Are Particularly Important For Specific Underlying Funds:
 
 ^Concentration Risk--The European Equity Fund invests primarily in equity
  securities of European companies. The Japanese Equity Fund invests primar-
  ily in equity securities of Japanese companies. The Global Income Fund may
  invest more than 25% of its total assets in the securities of corporate and
  governmental issuers located in each of Canada, Germany, Japan, and the
  United Kingdom as well as in the securities of U.S. issuers. Concentration
  of the investments of these or other Underlying Funds in issuers located in
  a particular country or region will subject the Underlying Fund, to a
  greater extent than if investments were not so concentrated, to the risks
  of adverse securities markets, exchange rates and social, political, regu-
  latory or economic events which may occur in that country or region.
 ^Foreign Risks--Underlying Funds that invest in foreign securities will be
  subject to risks with respect to their foreign investments that are not
  typically associated with domestic issuers. These risks result from less
  government regulation, less public information and less economic, political
  and social stability. These risks may involve the imposition of exchange
  controls, confiscation and other government restrictions. The Underlying
  Funds will also be subject to the risk of negative foreign currency rate
  fluctuations. Foreign risks will normally be greatest when an Underlying
  Fund invests in issuers located in emerging countries.

                                         PRINCIPAL RISKS OF THE UNDERLYING FUNDS
 
 ^Emerging Markets Risk--The securities markets of Asian, Latin American,
  Eastern European, African and other emerging countries are less liquid, are
  especially subject to greater price volatility, have smaller market capi-
  talizations, have less government regulation and are not subject to as
  extensive and frequent accounting, financial and other reporting require-
  ments as the securities markets of more developed countries. Further,
  investment in equity securities of issuers located in Russia and certain
  other emerging countries involves risk of loss resulting from problems in
  share registration and custody and substantial economic and political dis-
  ruptions. These risks are not normally associated with investments in more
  developed countries.
 ^"Junk Bond" Risk--The High Yield Fund will invest in non-investment grade
  fixed-income securities (commonly known as "junk bonds") that are consid-
  ered predominantly speculative by traditional investment standards. Non-
  investment grade fixed-income securities and unrated securities of compara-
  ble credit quality are subject to the increased risk of an issuer's
  inability to meet principal and interest payment obligations. These securi-
  ties may be subject to greater price volatility due to such factors as spe-
  cific corporate developments, interest rate sensitivity, negative percep-
  tions of the junk bond markets generally and less secondary market
  liquidity.
 ^Small Cap Stock and REIT Risks--The securities of small capitalization com-
  panies and REITs involve greater risks than those associated with larger,
  more established companies, and the securities may be subject to more
  abrupt or erratic price movements. Securities of such issuers may lack suf-
  ficient market liquidity to enable an Underlying Fund to effect sales at an
  advantageous time or without a substantial drop in price.
 
More information about the portfolio securities and investment techniques of
the Underlying Funds, and their associated risks, is provided in Appendix A.
You should consider the investment risks discussed in this section and in
Appendix A. Both are important to your investment choice.

Portfolio Performance
 
 HOW THE PORTFOLIOS HAVE PERFORMED
 
 
 The bar charts and tables below provide an indication of the risks of
 investing in a Portfolio by showing: (a) changes in the performance of a
 Portfolio's Class A Shares from year to year; and (b) how the average annual
 returns of a Portfolio's Class A, B and C Shares compare to those of a
 broad-based securities market index. The bar chart and table assume rein-
 vestment of dividends and distributions. A Portfolio's past performance is
 not necessarily an indication of how the Portfolio will perform in the
 future. The average annual total return calculation reflects a maximum ini-
 tial sales charge of 5.5% for Class A Shares, the assumed contingent
 deferred sales charge ("CDSC") for Class B Shares (5% maximum declining to
 0% after six years), and the assumed CDSC for Class C Shares (1% if redeemed
 within 12 months of purchase). The bar charts do not reflect the sales loads
 applicable to Class A Shares. If the sales loads were reflected, returns
 would be less. Performance reflects expense limitations in effect. If
 expense limitations were not in place, a Portfolio's performance would have
 been reduced. The Conservative Strategy Portfolio did not commence opera-
 tions until February 8, 1999. Since the Portfolio has less than one calendar
 year's performance, no performance information is provided in this section.

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

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

The hypothetical example assumes that a CDSC will not apply to redemptions of
Class A Shares within the first 18 months. Class B Shares convert to Class A
Shares eight years after purchase; therefore, Class A expenses are used in the
hypothetical example after year eight.
 
Certain institutions that sell Class A, Class B and Class C Shares on behalf of
their customers may receive other compensation in connection with the sale and
distribution of Class A, Class B and Class C Shares or for services to their
accounts and/or the Portfolios. For additional information regarding such com-
pensation, see "Shareholder Guide" in the Prospectus and "Other Information" in
the Additional Statement.

 PERSONAL ACCOUNT MAINTENANCE SERVICES AND FEES
 
 
 Under the Plans, Goldman Sachs is also entitled to receive a separate fee
 equal on an annual basis to 0.25% of each Fund's average daily net assets
 attributed to Class A Shares, Class B or Class C Shares. This fee is for
 personal and account maintenance services, and may be used to make payments
 to Goldman Sachs, Authorized Dealers and their officers, sales representa-
 tives and employees for responding to inquiries of, and furnishing assis-
 tance to, shareholders regarding ownership of their shares or their accounts
 or similar services not otherwise provided on behalf of the Funds. If the
 fees received by Goldman Sachs pursuant to the Plans exceed its expenses,
 Goldman Sachs may realize a profit from this arrangement.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.25% service fee as an ongoing commission to Authorized Dealers after
 the shares have been held for one year.

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

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

 DISTRIBUTOR AND TRANSFER AGENT
 
 
 Goldman Sachs, 85 Broad Street, New York, New York 10004, serves as the
 exclusive distributor (the "Distributor") of each Fund's shares. Goldman
 Sachs, 4900 Sears Tower, Chicago, Illinois, 60606, also serves as Funds'
 transfer agent (the "Transfer Agent") and as such, performs various share-
 holder servicing functions.
 
 From time to time, Goldman Sachs or any of its affiliates may purchase and
 hold shares of the Underlying Funds or Portfolios. Goldman Sachs reserves
 the right to redeem at any time some or all of the shares acquired for its
 own amount.
 
 ACTIVITIES OF GOLDMAN SACHS AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED BY
 GOLDMAN SACHS
 
 
 The involvement of the Investment Adviser, Goldman Sachs and their affili-
 ates in the management of, or their interest in, other accounts and other
 activities of Goldman Sachs may present conflicts of interest with respect
 to an Underlying Fund or limit an Underlying Fund's investment activities.
 Goldman Sachs and its affiliates engage in proprietary trading and advise
 accounts and funds which have investment objectives similar to those of the
 Underlying Funds and/or which engage in and compete for transactions in the
 same types of securities, currencies and instruments as the Underlying
 Funds. Goldman Sachs and its affiliates will not have any obligation to make
 available any information regarding their proprietary activities or strate-
 gies, or the activities or strategies used for other accounts managed by
 them, for the benefit of the management of the Underlying Funds. The results
 of an Underlying Fund's investment activities, therefore, may differ from
 those of Goldman Sachs and its affiliates, and it is possible that an Under-
 lying Fund could sustain losses during periods in which Goldman Sachs and
 its affiliates and other accounts achieve significant profits on their trad-
 ing for proprietary or other accounts. In addition, the Underlying Funds
 may, from time to time, enter into transactions in which other clients of
 Goldman Sachs have an adverse interest. An Underlying Fund's activities may
 be limited because of regulatory restrictions applicable to Goldman Sachs
 and its affiliates, and/or their internal policies designed to comply with
 such restrictions.
 
 YEAR 2000
 
 
 Many computer systems were designed using only two digits to signify the
 year (for example, "98" for "1998"). On January 1, 2000, if these computer
 systems are not corrected, they may incorrectly interpret "00" as the year
 "1900" rather
 
                                                                            5-AA
<PAGE>
 
 
 than the year "2000," leading to computer shutdowns or errors (commonly
 known as the "Year 2000 Problem"). To the extent these systems conduct for-
 ward-looking calculations, these computer problems may occur prior to Janu-
 ary 1, 2000. Like other investment companies and financial and business
 organizations, the Portfolios and the Underlying Funds could be adversely
 affected in their ability to process securities trades, price securities,
 provide shareholder account services and otherwise conduct normal business
 operations if the Investment Adviser or other service providers do not ade-
 quately address this problem in a timely manner.
 
 In order to address the Year 2000 Problem, the Investment Adviser has taken
 the following measures:
 
..The Investment Adviser has established a dedicated group to analyze these
  issues and to implement the systems modifications necessary to prepare for
  the Year 2000 Problem.
..The Investment Adviser has sought assurances from the Portfolios' other
  service providers that they are taking the steps necessary so that they do
  not experience Year 2000 Problems, and the Investment Adviser will continue
  to monitor the situation.
 
 Currently, the Investment Adviser does not anticipate that the transition to
 the 21st century will have any material impact on its ability to continue to
 service the Portfolios at current levels.
 
 In addition, the Investment Adviser has undertaken measures to appropriately
 take into account available information concerning the Year 2000 prepared-
 ness of the issuers of securities held by the Portfolios. The Investment
 Adviser may obtain such Year 2000 information from various sources which the
 Investment Adviser believes to be reliable, including the issuers' public
 regulatory filings. However, the Investment Adviser is not in a position to
 verify the accuracy or completeness of such information.
 
 At this time, however, no assurance can be given that the actions taken by
 the Investment Adviser and the Portfolios' other service providers will be
 sufficient to avoid any adverse effect on the Portfolios due to the Year
 2000 Problem.

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

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

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

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

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

     tions, the entire sales charge may be reallowed to Authorized Dealers.
     Authorized Dealers to whom substantially the entire sales charge is

     1933.
  ** No sales charge is payable at the time of purchase of Class A Shares of
     $1 million or more, but a CDSC of 1% may be imposed in the event of cer-
     tain redemptions within 18 months of purchase.

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

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

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

 COMMON QUESTIONS ABOUT THE PURCHASE OF CLASS B SHARES
 
 
 What Is The Offering Price Of Class B Shares?
 You may purchase Class B Shares of the Funds at the next determined NAV
 without an initial sales charge. However, Class B Shares redeemed within six
 years of purchase will be subject to a CDSC at the rates shown in the table
 below based on how long you held your shares.
 
 The CDSC schedule is as follows:

  Sixth                          1%
  Seventh and thereafter       None
 ----------------------------------------
</TABLE>
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or part to defray the Distributor's expenses related to providing dis-
 tribution-related services to the Funds in connection with the sale of Class
 B Shares, including the payment of compensation to Authorized Dealers. A
 commission equal to 4% of the amount invested is paid to Authorized Dealers.
 
 What Should I Know About The Automatic Conversion Of Class B Shares?
 Class B Shares of a Fund will automatically convert into Class A Shares of
 the same Fund at the end of the calendar quarter that is eight years after
 the purchase date.
 
 If you acquire Class B Shares of a Fund by exchange from Class B Shares of
 another Goldman Sachs Fund, your Class B Shares will convert into Class A
 Shares of such Fund based on the date of the initial purchase and the CDSC
 schedule of that purchase.
 
 If you acquire Class B Shares through reinvestment of distributions, your
 Class B Shares will convert into Class A Shares based on the date of the
 initial purchase of the shares on which the distribution was paid.
 
 The conversion of Class B Shares to Class A Shares will not occur at any
 time the Funds are advised that such conversions may constitute taxable
 events for federal tax purposes, which the Funds believe is unlikely. If
 conversions do not occur as a
 
                                                                             7-C
<PAGE>
 
 result of possible taxability, Class B Shares would continue to be subject
 to higher expenses than Class A Shares for an indeterminate period.
 
 A COMMON QUESTION ABOUT THE PURCHASE OF CLASS C SHARES
 
 
 What Is The Offering Price Of Class C Shares?
 You may purchase Class C Shares of the Funds at the next determined NAV
 without paying an initial sales charge. However, if you redeem Class C
 Shares within 12 months of purchase, a CDSC of 1% will be deducted from the
 redemption proceeds.
 
 Proceeds from the CDSC are payable to the Distributor and may be used in
 whole or in part to defray the Distributor's expenses related to providing
 distribution-related services to the Funds in connection with the sale of
 Class C Shares, including the payment of compensation to Authorized Dealers.
 An amount equal to 1% of the amount invested is paid by the Distributor to
 Authorized Dealers.
 
 COMMON QUESTIONS APPLICABLE TO THE PURCHASE OF CLASS A, B
 AND C SHARES
 
 
 What Else Do I Need To Know About The CDSC On Class A, B Or C Shares?
..The CDSC is based on the lesser of the NAV of the shares at the time of
  redemption or the original offering price (which is the original NAV).
  .No CDSC is charged on shares acquired from reinvested dividends or capi-
   tal gains distributions.
  .No CDSC is charged on the per share appreciation of your account over the
   initial purchase price.
  .When counting the number of months since a purchase of Class B or Class C
   Shares was made, all payments made during a month will be combined and
   considered to have been made on the first day of that month.
..To keep your CDSC as low as possible, each time you place a request to sell
  shares, the Funds will first sell any shares in your account that do not
  carry a CDSC and then the shares in your account that have been held the
  longest.
 
 In What Situations May The CDSC On Class A, B Or C Shares Be Waived Or
 Reduced?
 The CDSC on Class A, Class B and Class C Shares that are subject to a CDSC
 may be waived or reduced if the redemption relates to:
..Retirement distributions or loans to participants or beneficiaries from
  pension and profit sharing plans, pension funds and other company-sponsored
  benefit plans (each a "Retirement Plan");

..The death or disability (as defined in Section 72(m)(7) of the Internal
  Revenue Code of 1986, as amended (the "Code")) of a participant or benefi-
  ciary in a Retirement Plan;
..Hardship withdrawals by a participant or beneficiary in a Retirement Plan;
..Satisfying the minimum distribution requirements of the Code;
..Establishing "substantially equal periodic payments" as described under
  Section 72(t)(2) of the Code;
..The separation from service by a participant or beneficiary in a Retirement
  Plan;
..The death or disability (as defined in Section 72(m)(7) of the Code) of a
  shareholder if the redemption is made within one year of the event;
..Excess contributions distributed from a Retirement Plan;
..Distributions from a qualified Retirement Plan invested in the Goldman
  Sachs Funds which are being rolled over to a Goldman Sachs IRA; or
..Redemption proceeds which are to be reinvested in accounts or non-regis-
  tered products over which GSAM or its advisory affiliates have investment
  discretion.
 
 In addition, Class A, B and C Shares subject to a systematic withdrawal plan
 may be redeemed without a CDSC. The Funds reserve the right to limit such
 redemptions, on an annual basis, to 12% each of the value of your Class B
 and C Shares and 10% of the value of your Class A Shares.
 
 How Do I Decide Whether To Buy Class A, B Or C Shares?
 The decision as to which Class to purchase depends on the amount you invest,
 the intended length of the investment and your personal situation.
 
..Class A Shares. If you are making an investment of $50,000 or more that
  qualifies for a reduced sales charge, you should consider purchasing Class
  A Shares.
..Class B Shares. If you plan to hold your investment for at least six years
  and would prefer not to pay an initial sales charge, you might consider
  purchasing Class B Shares. By not paying a front-end sales charge, your
  entire investment in Class B Shares is available to work for you from the
  time you make your initial investment. However, the distribution and serv-
  ice fee paid by Class B Shares will cause your Class B Shares (until con-
  version to Class A Shares) to have a higher expense ratios, and thus, lower
  performance and lower dividend payments (to the extent dividends are paid)
  than Class A Shares.
  A maximum purchase limitation of $250,000 in the aggregate normally
  applies to Class B Shares.
..Class C Shares. If you are unsure of the length of your investment or plan
  to hold your investment for less than six years and would prefer not to pay
  an
 
                                                                             9-C
<PAGE>
 
  initial sales charge, you may prefer Class C Shares. By not paying a front-
  end sales charge, your entire investment in Class C Shares is available to
  work for you from the time you make your initial investment. However, the
  distribution and service fee paid by Class C Shares will cause your Class C
  Shares to have a higher expense ratio, and thus lower performance and lower
  dividend payments (to the extent dividends are paid), than Class A Shares
  (or Class B Shares after conversion to Class A Shares).
  Although Class C Shares are subject to a CDSC for only 12 months, Class C
  Shares do not have the conversion feature applicable to Class B Shares and
  your investment will therefore pay higher distribution fees indefinitely.
  A maximum purchase limitation of $1,000,000 in the aggregate normally
  applies to purchases of Class C Shares.
 
 Note: Authorized Dealers may receive different compensation for selling
 Class A, Class B or Class C Shares.
 
 In addition to Class A, Class B and Class C Shares, each Fund also offers
 other classes of shares to investors. These other share classes are subject
 to different fees and expenses (which affect performance), have different
 minimum investment requirements and are entitled to different services.
 Information regarding these other share classes may be obtained from your
 sales representative or from Goldman Sachs by calling the number on the back
 cover of this Prospectus.
 
 HOW TO SELL SHARES
 
 
 How Can I Sell Class A, Class B And Class C Shares Of The Funds?
 You may arrange to take money out of your account by selling (redeeming)
 some or all of your shares. Each Fund will redeem its shares upon request on
 any business day at the NAV next determined after receipt of such request in
 proper form, subject to any applicable CDSC. You may request that redemption
 proceeds be sent to you by check or by wire (if the wire instructions are on
 record). Redemptions may be requested in writing or by telephone.

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

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

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

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

..You must invest an amount in the Fund into which cross-reinvestments or
  automatic exchanges are being made that is equal to that Fund's minimum
  initial investment or continue to cross-reinvest or to make automatic
  exchanges until such minimum initial investment is met.
..You should obtain and read the prospectus of the Fund into which dividends
  are invested or automatic exchanges are made.
 
 Can I Have Automatic Withdrawals Made On A Regular Basis?
 You may draw on your account systematically via check or ACH transfer in any
 amount of $50 or more.
..It is normally undesirable to maintain a systematic withdrawal plan at the
  same time that you are purchasing additional Class A, Class B or Class C
  Shares because of the sales charge imposed on your purchases of Class A
  Shares or the imposition of a CDSC on your redemptions of Class A, Class B
  or Class C Shares.
..You must have a minimum balance of $5,000 in a Fund.
..Checks are mailed on or about the 25th day of each month.
..Each systematic withdrawal is a redemption and therefore a taxable transac-
  tion.
..The CDSC applicable to Class A, Class B or Class C Shares redeemed under
  the systematic withdrawal plan may be waived.
 
 What Types of Reports Will I Be Sent Regarding My Investment?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-526-7384. You will also be provided with a
 printed confirmation for each transaction in your account and an individual
 quarterly account statement. A year-to-date statement for your account will
 be provided upon request made to Goldman Sachs. If your account is held in
 "street name" you may receive your statement and confirmations on a differ-
 ent schedule. The Funds do not generally provide sub-accounting services.
 
 What Should I Know When I Purchase Shares Through An Authorized Dealer?
 Authorized Dealers and other financial intermediaries may provide varying
 arrangements for their clients to purchase and redeem Fund shares. They may
 charge additional fees not described in this Prospectus to their customers
 for such services.
 
 If shares of a Fund are held in a "street name" account with an Authorized
 Dealer, all recordkeeping, transaction processing and payments of distribu-
 tions relating to your account will be performed by the Authorized Dealer,
 and not by the Fund and its Transfer Agent. Since the Funds will have no
 record of your
 
                                                                            17-C

 transactions, you should contact the Authorized Dealer to purchase, redeem
 or exchange shares, to make changes in or give instructions concerning the
 account or to obtain information about your account. The transfer of shares
 in a "street name" account to an account with another dealer or to an
 account directly with the Fund involves special procedures and will require
 you to obtain historical purchase information about the shares in the
 account from the Authorized Dealer.
 
 Authorized Dealers and other financial intermediaries may be authorized to
 accept, on behalf of the Trust, purchase, redemption and exchange orders
 placed by or on behalf of their customers, and if approved by the Trust, to
 designate other intermediaries to accept such orders. In these cases:
..A Fund will be deemed to have received an order that is in proper form when
  the order is accepted by an Authorized Dealer or intermediary on a business
  day, and the order will be priced at the Fund's NAV per share (adjusted for
  any applicable sales charge) next determined after such acceptance.
..Authorized Dealers and intermediaries are responsible for transmitting
  accepted orders to the Funds within the time period agreed upon by them.
 
 You should contact your Authorized Dealer or intermediary to learn whether
 they are authorized to accept orders for the Trust.
 
 The Investment Adviser, Distributor and/or their affiliates may pay addi-
 tional compensation from time to time, out of their assets and not as an
 additional charge to the Funds, to selected Authorized Dealers and other
 persons in connection with the sale, distribution and/or servicing of shares
 of the Funds and other Goldman Sachs Funds. Subject to applicable NASD regu-
 lations, the Investment Adviser, Distributor and/or their affiliates may
 also contribute to various cash and non-cash incentive arrangements to pro-
 mote the sale of shares. This additional compensation can vary among Autho-
 rized Dealers depending upon such factors as the amounts their customers
 have invested (or may invest) in particular Goldman Sachs Funds, the partic-
 ular program involved, or the amount of reimbursable expenses. Additional
 compensation based on sales may, but is currently not expected to, exceed
 0.50% (annualized) of the amount invested.
 
 DISTRIBUTION SERVICES AND FEES
 
 
 What Are The Different Distribution And Service Fees Paid By Class A, B and
 C Shares?
 The Trust has adopted distribution and service plans (each a "Plan") under
 which Class A, Class B and Class C Shares bear distribution and service fees
 paid to Authorized Dealers and Goldman Sachs. If the fees received by
 Goldman Sachs pursuant to the Plans exceed its expenses, Goldman Sachs may
 realize a profit from

                                                               SHAREHOLDER GUIDE
 
 this arrangement. Goldman Sachs pays the distribution and service fees on a
 quarterly basis.
 
 Under the Plans, Goldman Sachs is entitled to a monthly fee from each Fund
 for distribution services equal, on an annual basis, to 0.25%, 0.75% and
 0.75%, respectively, of a Fund's average daily net assets attributed to
 Class A, Class B and Class C Shares. Because these fees are paid out of the
 Fund's assets on an ongoing basis, over time, these fees will increase the
 cost of your investment and may cost you more than paying other types of
 such charges.
 
 The distribution fees are subject to the requirements of Rule 12b-1 under
 the 1940 Act, and may be used (among other things) for:
..Compensation paid to and expenses incurred by Authorized Dealers, Goldman
  Sachs and their respective officers, employees and sales representatives;
..Commissions paid to Authorized Dealers;
..Allocable overhead;
..Telephone and travel expenses;
..Interest and other costs associated with the financing of such compensation
  and expenses;
..Printing of prospectuses for prospective shareholders;
..Preparation and distribution of sales literature or advertising of any
  type; and
..All other expenses incurred in connection with activities primarily
  intended to result in the sale of Class A, Class B and Class C Shares.
 
 In connection with the sale of Class C Shares, Goldman Sachs begins paying
 the 0.75% distribution fee as an ongoing commission to Authorized Dealers
 after the shares have been held for one year.
 
                                                                            19-C

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

Appendix A
 
Additional Information on the Underlying Funds
 This Appendix provides further information on certain types of securities
 and techniques that may be used by the Underlying Funds, including their
 associated risks. Additional information is provided in the Additional
 Statement, which is available upon request, and in the prospectuses of the
 Underlying Funds.
 
 The Underlying Equity Funds invest primarily in common stocks and other
 equity securities, including preferred stocks, interests in real estate
 investment trusts, convertible debt obligations, convertible preferred
 stocks, equity interests in trusts, partnerships, joint ventures, limited
 liability companies and similar enterprises, warrants and stock purchase
 rights ("equity securities"). The Underlying Fixed-Income Funds invest pri-
 marily in fixed-income securities, including senior and subordinated corpo-
 rate debt obligations (such as bonds, debentures, notes and commercial
 paper), convertible and non-convertible corporate debt obligations, loan
 participations and preferred stock.
 
 The Short Duration Government and Adjustable Rate Government Funds invest in
 U.S. Government Securities and related repurchase agreements, and neither of
 these Funds, the Government Income Fund nor the Financial Square Prime Obli-
 gations Fund makes foreign investments. The investments of the Financial
 Square Prime Obligations Fund are limited by SEC regulations applicable to
 money market funds as described in its prospectus, and do not include many
 of the types of investments discussed below that are permitted for the other
 Underlying Funds. With these exceptions, and the further exceptions noted
 below, the following description applies generally to the Underlying Funds.
 
 A. Description of the Underlying Funds
 
 Underlying Equity Funds
 The investment advisers of the Underlying Equity Funds may, in choosing
 securities, utilize first-hand fundamental research, including visiting com-
 pany facilities to assess operations and to meet decision-makers. The
 investment advisers may also use macro analysis of numerous economic and
 valuation variables to anticipate changes in company earnings and the over-
 all investment climate. The investment advisers are able to draw on the
 research and market expertise of the Goldman Sachs Global Investment
 Research Department and other affiliates, as well as information provided by
 other securities dealers. Equity securities held by an Underlying Equity
 Fund will generally be sold when an investment adviser
 
                                                                            3-NN

 believes that the market price fully reflects or exceeds the securities'
 fundamental valuation or when other more attractive investments are identi-
 fied.
 
 Domestic Value Style Funds. The Growth and Income, Mid Cap Value and Small
 Cap Value Funds are managed using a value oriented approach. The Funds'
 investment adviser evaluates securities using fundamental analysis and
 intends to purchase equity securities that are, in its view, underpriced
 relative to a combination of such companies' long-term earnings prospects,
 growth rate, free cash flow and/or dividend-paying ability.
 
 Consideration will be given to the business quality of the issuer. Factors
 positively affecting the investment adviser's view of that quality include
 the competitiveness and degree of regulation in the markets in which the
 company operates, the existence of a management team with a record of suc-
 cess, the position of the company in the markets in which it operates, the
 level of the company's financial leverage and the sustainable return on cap-
 ital invested in the business. These Underlying Funds may also purchase
 securities of companies that have experienced difficulties and that, in the
 opinion of the investment adviser, are available at attractive prices.
 
 Domestic Growth Style Fund. The Capital Growth Fund is managed using a
 growth oriented approach. Equity securities for this Fund are selected based
 on their prospects for above average growth. The Fund's investment adviser
 will select securities of growth companies trading, in the investment advis-
 er's opinion, at a reasonable price relative to other industries, competi-
 tors and historical price/ earnings multiples. The Fund will generally
 invest in companies whose earnings are believed to be in a relatively strong
 growth trend or, to a lesser extent, in companies in which significant fur-
 ther growth is not anticipated but whose market value per share is thought
 to be undervalued.
 
 Quantitative Style Funds. The CORE U.S. Equity, CORE Large Cap Growth, CORE
 Large Cap Value, CORE Small Cap Equity and CORE International Equity Funds
 (the "CORE Equity Funds") are managed using both quantitative and fundamen-
 tal techniques. CORE is an acronym for "Computer-Optimized, Research-
 Enhanced," which reflects the Funds' investment process. This investment
 process and the proprietary multifactor model used to implement it are dis-
 cussed below.
 
 Quantitative Investment Process. The Funds' investment advisers begin with a
 broad universe of U.S. equity securities for the CORE U.S. Equity, CORE
 Large Cap Growth, CORE Large Cap Value and CORE Small Cap Equity Funds (the
 "CORE U.S. Equity Funds"), and a broad universe of foreign equity securities
 for the CORE International Equity Fund. The investment advisers use proprie-
 tary multifactor models (each a "Multifactor Model") to forecast the returns
 of differ-

                                                                      APPENDIX A
 
 ent markets, currencies and individual securities. In the case of an U.S.
 equity security followed by the Goldman Sachs Global Investment Research
 Department (the "Research Department"), a rating is assigned based upon the
 Research Department's evaluation. In the discretion of the investment advis-
 er, ratings may also be assigned to U.S. equity securities based on research
 ratings obtained from other industry sources. In the case of a foreign
 equity security, an investment adviser may rely on research from both the
 Research Department and other industry sources.
 
 In building a diversified portfolio for each CORE Equity Fund, an investment
 adviser utilizes optimization techniques to seek to maximize the Fund's
 expected return, while maintaining a risk profile similar to the Fund's
 benchmark. Each portfolio consists primarily of securities rated highest by
 the foregoing investment process and has risk characteristics and industry
 weightings similar to the relevant Fund's benchmark.
 
 Quantitative Multifactor Models. The Multifactor Models are rigorous comput-
 erized rating systems for forecasting the returns of different equity mar-
 kets, currencies, and individual equity securities according to fundamental
 investment characteristics. The CORE U.S. Equity Funds use one Multifactor
 Model to forecast the returns of securities held in each Fund's portfolio.
 The CORE International Equity Fund uses multiple Multifactor Models to fore-
 cast returns. Currently, the CORE International Equity Fund uses one model
 to forecast equity market returns, one model to forecast currency returns
 and 22 separate models to forecast individual equity security returns in 22
 different countries. Despite this variety, all Multifactor Models incorpo-
 rate common variables covering measures of value, growth, momentum and risk
 (e.g., book/price ratio, earnings/price ratio, price momentum, price vola-
 tility, consensus growth forecasts, earnings estimate revisions, earnings
 stability, and, in the case of models for the CORE International Equity
 Fund, currency momentum and country political risk ratings). All of the fac-
 tors used in the Multifactor Models have been shown to significantly impact
 the performance of the securities, currencies and markets they were designed
 to forecast.
 
 The weightings assigned to the factors in the Multifactor Model used by the
 CORE U.S. Equity Funds are derived using a statistical formulation that con-
 siders each factor's historical performance in different market environ-
 ments. As such, the U.S. Multifactor Model is designed to evaluate each
 security using only the factors that are statistically related to returns in
 the anticipated market environment. Because they include many disparate fac-
 tors, the Funds' investment advisers believe that all the Multifactor Models
 are broader in scope and provide a more thorough evaluation than most con-
 ventional, quantitative models. Securities
 
                                                                            5-NN
<PAGE>
 
 
 and markets ranked highest by the relevant Multifactor Model do not have one
 dominant investment characteristic; rather, they possess an attractive com-
 bination of investment characteristics.
 
 Research Department. In assigning ratings to equity securities, the Research
 Department uses a four category rating system ranging from "recommended for
 purchase" to "likely to underperform." The ratings reflect the analyst's
 judgment as to the investment results of a specific security and incorporate
 economic outlook, valuation, risk and a variety of other factors.
 
 By employing both a quantitative (i.e., the Multifactor Models) and a quali-
 tative (i.e., research enhanced) method of selecting securities, each CORE
 Equity Fund seeks to capitalize on the strengths of each discipline.
 
 Actively Managed International Funds. The International Equity, Japanese
 Equity, European Equity, International Small Cap, Emerging Markets Equity
 and Asia Growth Funds are managed using an active international approach.
 This approach utilizes a consistent process of stock selection undertaken by
 portfolio management teams located within each of the major investment
 regions, including Europe, Japan, Asia and the United States. In selecting
 securities, the investment adviser uses a long-term, bottom-up strategy
 based on first-hand fundamental research that is designed to give broad
 exposure to the available opportunities while seeking to add return primar-
 ily through stock selection. Equity securities for these Funds are evaluated
 based on three key factors--the business, the management and the valuation.
 The investment adviser ordinarily seeks securities that have, in its opin-
 ion, superior earnings growth potential, sustainable franchise value with
 management attuned to creating shareholder value and relatively discounted
 valuations. In addition, the investment adviser uses a multi-factor risk
 model which seeks to assure that deviations from the benchmark are justifi-
 able.
 
 Real Estate Securities Fund. The investment strategy of the Real Estate
 Securities Fund is based on the premise that property market fundamentals
 are the primary determinant of growth underlying the success of companies in
 the real estate industry. The Fund's research and investment process is
 designed to identify those companies with strong property fundamentals and
 strong management teams. This process is includes real estate market
 research and securities analysis. The Fund's investment adviser will take
 into account fundamental trends in underlying property markets as determined
 by proprietary models, research of local real estate markets, earnings, cash
 flow growth and stability, the relationship between asset values and market
 prices of the securities and dividend payment history. The investment
 adviser will attempt to purchase securities so that its underlying portfolio
 will be diversified geographically and by property type.

 Underlying Fixed-Income Funds
 As stated above, each Underlying Fixed-Income Fund has policies relating to
 its duration (or maturity in the case of the Financial Square Prime Obliga-
 tions Fund). A Fund's duration approximates its price sensitivity to changes
 in interest rates. Maturity measures the time until final payment is due; it
 takes no account of the pattern of a security's cash flows over time. In
 computing portfolio duration, an Underlying Fixed-Income Fund will estimate
 the duration of obligations that are subject to prepayment or redemption by
 the issuer taking into account the influence of interest rates on prepay-
 ments and coupon flows. This method of computing duration is known as
 "option-adjusted" duration. A Fund will not be limited as to its maximum
 weighted average portfolio maturity or the maximum stated maturity with
 respect to individual securities unless otherwise noted.
 
 Except for the Financial Square Prime Obligations Fund (which is subject to
 more restrictive SEC regulations applicable to money market funds), an
 Underlying Fixed-Income Fund will deem a security to have met its minimum
 credit rating requirement if the security receives the minimum required
 long-term rating (or the equivalent short-term credit rating) at the time of
 purchase from at least one rating organization (including, but not limited
 to, Standard & Poor's Ratings Group ("S&P") and Moody's Investors Service,
 Inc. ("Moody's")) even though it has been rated below the minimum rating by
 one or more other rating organizations, or, if unrated by a rating organiza-
 tion, is determined by the Fund's investment adviser to be of comparable
 quality. If a security satisfies a Fund's minimum rating criteria at the
 time of purchase and is subsequently downgraded below such rating, the Fund
 will not be required to dispose of such security. If a downgrade occurs, the
 Fund's investment adviser will consider what action, including the sale of
 such security, is in the best interest of the Fund and its shareholders.
 
 The Underlying Fixed-Income Funds may (but are not required to) employ cer-
 tain active management techniques to manage their duration and term struc-
 ture, to seek to hedge exposure to foreign currencies and to seek to enhance
 returns. These techniques include (with respect to one or more of the
 Funds), but are not limited to, the use of financial futures contracts,
 option contracts (including options on futures), forward foreign currency
 exchange contracts, currency options and futures, currency, mortgage, credit
 and interest rate swaps and interest rate floors, caps and collars. Currency
 and interest rate management techniques involve risks different from those
 associated with investing solely in U.S. dollar-denominated fixed-income
 securities of U.S. issuers. Certain of the Funds may invest in custodial
 receipts, municipal securities and convertible securities. The Funds may
 also employ other investment techniques to seek to enhance returns, such as
 lending portfolio securities and entering into mortgage dollar rolls, repur-
 chase agreements, reverse repurchase agreements and other investment prac-
 tices.
 
                                                                            7-NN

 B. General Risks of the Underlying Funds
 
 The Underlying Equity Funds will be subject to the risks associated with
 common stocks and other equity securities. In general, stock values fluctu-
 ate in response to the activities of individual companies and in response to
 general market and economic conditions. Accordingly, the value of the stocks
 that a Fund holds may decline over short or extended periods. The stock mar-
 kets tend to be cyclical, with periods when stock prices generally rise and
 periods when prices generally decline.
 
 The Underlying Fixed-Income Funds will be subject to the risks associated
 with fixed-income securities. These risks include interest rate risk, credit
 risk and call/extension risk, In general, interest rate risk involves the
 risk that when interest rates decline, the market value of fixed-income
 securities tends to decline. Credit risk involves the risk that the issuer
 could default on its obligations and a Fund will not recover its investment.
 Call risk and extension risk are normally present in adjustable rate mort-
 gage loans ("ARMs"), mortgage-backed securities and asset-backed securities.
 For example, homeowners have the option to prepay their mortgages. There-
 fore, the duration of a security backed by home mortgages can either shorten
 (call risk) or lengthen (extension risk). In general, if interest rates on
 new mortgage loans fall sufficiently below the interest rates on existing
 outstanding mortgage loans, the rate of prepayment would be expected to
 increase. Conversely, if mortgage loan interest rates rise above the inter-
 est rates on existing outstanding mortgage loans, the rate of prepayment
 would be expected to decrease. In either case, a change in the prepayment
 rate can result in losses to investors.
 
 The Financial Square Prime Obligations Fund attempts to maintain a stable
 NAV of $1.00 per share and values its assets using the amortized cost method
 in accordance with SEC regulations. There is no assurance, however, that the
 Financial Square Prime Obligations Fund will be successful in maintaining
 its per share value at $1.00 on a continuous basis. The per share NAVs of
 the other Underlying Funds are expected to fluctuate on a daily basis.
 
 The turnover rates of the Underlying Funds have ranged from 41% to 315% dur-
 ing their most recent fiscal years. There can be no assurance that the turn-
 over rates of the Underlying Funds will remain within this range during sub-
 sequent fiscal years. Higher turnover rates may result in higher brokerage
 costs and expenses for the Underlying Funds. In addition, higher turn-
 over rates may result in higher taxable realized gains for shareholders.

 C. Other Risks of the Underlying Funds
 
 Risks of Investing in Small Capitalization Companies and REITs. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such securities. Small capitalization companies
 and REITs may be thinly traded and may have to be sold at a discount from
 current market prices or in small lots over an extended period of time. In
 addition, these securities are subject to the risk that during certain peri-
 ods the liquidity of particular issuers or industries, or all securities in
 these investment categories, will shrink or disappear suddenly and without
 warning as a result of adverse economic or market conditions, or adverse
 investor perceptions, whether or not accurate. Because of the lack of suffi-
 cient market liquidity, an Underlying Fund may incur losses because it will
 be required to effect sales at a disadvantageous time and only then at a
 substantial drop in price. Small capitalization companies and REITs also
 often have limited product lines, markets or financial resources; may depend
 on or use a few key personnel for management; and may be susceptible to
 losses and risks of bankruptcy. Transaction costs for these investments are
 often higher than those for larger capitalization companies. Investments in
 small capitalization companies and REITs may be more difficult to price pre-
 cisely than other types of securities because of their characteristics and
 lower trading volumes.
 
 Risks of Derivative Investments. An Underlying Fund's transactions, if any,
 in options, futures, options on futures, swaps, interest rate caps, floors
 and collars, structured securities, inverse floating-rate securities,
 stripped mortgage-backed securities and currency transactions involve addi-
 tional risk of loss. Loss can result from a lack of correlation between
 changes in the value of derivative instruments and the portfolio assets (if
 any) being hedged, the potential illiquidity of the markets for derivative
 instruments, or the risks arising from margin requirements and related lev-
 erage factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the investment adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. The Underlying Funds may also invest in derivative
 investments for non-hedging purposes (that is, to seek to increase total
 return), which is considered as a speculative practice and presents even
 greater risk of loss.
 
 Derivative mortgage-backed securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact
 
                                                                            9-NN
<PAGE>
 
 
 the cash flow and the market value of these securities. In general, the risk
 of faster than anticipated prepayments adversely affects IOs, super floaters
 and premium priced mortgage-backed securities. The risk of slower than
 anticipated prepayments generally adversely affects POs, floating-rate secu-
 rities subject to interest rate caps, support tranches and discount priced
 mortgage-backed securities. In addition, particular derivative securities
 may be leveraged such that their exposure (i.e., price sensitivity) to
 interest rate and/or prepayment risk is magnified.
 
 Floating-rate derivative debt securities can present more complex types of
 derivative and interest rate risks. For example, range floaters are subject
 to the risk that the coupon will be reduced below market rates if a desig-
 nated interest rate floats outside of a specified interest rate band or col-
 lar. Dual index or yield curve floaters are subject to lower prices in the
 event of an unfavorable change in the spread between two designated interest
 rates.
 
 Risks of Foreign Investments. Certain of the Underlying Funds may invest in
 foreign securities in accordance with their investment objectives and poli-
 cies. Foreign investments involve special risks that are not typically asso-
 ciated with U.S. dollar denominated or quoted securities of U.S. issuers.
 Foreign investments may be affected by changes in currency rates, changes in
 foreign or U.S. laws or restrictions applicable to such investments and
 changes in exchange control regulations (e.g., currency blockage). A decline
 in the exchange rate of the currency (i.e., weakening of the currency
 against the U.S. dollar) in which a portfolio security is quoted or denomi-
 nated relative to the U.S. dollar would reduce the value of the portfolio
 security.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts after January 1, 1999 that refer to existing currencies
 rather than the euro; the establishment and maintenance of exchange rates
 for currencies being converted into the euro; the fluctuation of the euro
 relative to non-euro currencies during the transition period from January 1,
 1999 to December 31, 2001 and beyond; whether the interest rate, tax and
 labor regimes of European countries participating in the euro will converge
 over time; and whether the conversion of the currencies of other countries
 in the European Union ("EU"), such as the United Kingdom and Denmark, into
 the euro and the admission of other non-EU countries such as Poland, Latvia
 and Lithuania as members of the EU may have an impact on the euro. These or
 other factors, including political and economic risks, could cause market
 disruptions, and could adversely affect the value of securities held by the
 Underlying Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States.

                                                                      APPENDIX A
 
 In addition, clearance and settlement procedures may be different in foreign
 countries and, in certain markets, such procedures have been unable to keep
 pace with the volume of securities transactions, thus making it difficult to
 conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Furthermore, with respect to certain foreign countries, there is a
 possibility of nationalization, expropriation or confiscatory taxation,
 imposition of withholding or other taxes on dividend or interest payments
 (or, in some cases, capital gains), limitations on the removal of funds or
 other assets of the Underlying Funds, and political or social instability or
 diplomatic developments which could affect investments in those countries.
 
 Concentration of a Fund's assets in one of a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations involves risks not present in debt
 obligations of corporate issuers. The issuer of the debt or the governmental
 authorities that control the repayment of the debt may be unable or unwill-
 ing to repay principal or interest when due in accordance with the terms of
 such debt, and an Underlying Fund may have limited recourse to compel pay-
 ment in the event of a default. Periods of economic uncertainty may result
 in volatility of market prices of sovereign debt, and in turn the Underlying
 Fund's NAV, to a greater extent than the volatility inherent in debt obliga-
 tions of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Underlying Funds may also invest in European
 Depository Receipts ("EDRs") or other similar instruments representing secu-
 rities of foreign issuers. ADRs represent the right to receive securities of
 foreign issuers deposited
 
                                                                           11-NN
<PAGE>
 
 
 in a domestic bank or a correspondent bank. Prices of ADRs are quoted in
 U.S. dollars, and ADRs are traded in the United States. EDRs and GDRs are
 receipts evidencing an arrangement with a non-U.S. bank. EDRs and GDRs are
 not necessarily quoted in the same currency as the underlying security.
 
 Risks of Emerging Countries. Certain Underlying Funds may invest in securi-
 ties of issuers located in emerging countries. The risks of foreign invest-
 ment are heightened when the issuer is located in an emerging country. The
 International Equity, European Equity, International Small Cap, Emerging
 Markets Equity and Asia Growth Funds may each invest without limit in the
 securities of issuers in emerging countries. Up to 35% of the total assets
 of the Emerging Markets Equity Fund may be invested in securities of issuers
 in any one emerging country. The Growth and Income, Small Cap Value, Mid Cap
 Value, High Yield and CORE International Equity Funds may each invest up to
 25%, and the Core Fixed Income, Global Income and Capital Growth Funds may
 each invest up to 10%, of their respective total assets in securities of
 issuers in emerging countries.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, such as Taiwan, it is
 anticipated that a Fund may invest in such countries only through other
 investment funds in such countries.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant invest-
 
12-NN

                                                                      APPENDIX A
 
 ment losses. Investing in emerging countries involves greater risk of loss
 due to expropriation, nationalization, confiscation of assets and property
 or the imposition of restrictions on foreign investments and on repatriation
 of capital invested.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 An Underlying Fund's investment in emerging countries may also be subject to
 withholding or other taxes, which may be significant and may reduce the
 return from an investment in such country to the Underlying Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve an Under-
 lying Fund's delivery of securities before receipt of payment for their
 sale. In addition, significant delays are common in certain markets in reg-
 istering the transfer of securities. Settlement or registration problems may
 make it more difficult for an Underlying Fund to value its portfolio securi-
 ties and could cause the Underlying Fund to miss attractive investment
 opportunities, to have a portion of its assets uninvested or to incur losses
 due to the failure of a counterparty to pay for securities the Underlying
 Fund has delivered or the Underlying Fund's inability to complete its con-
 tractual obligations. The creditworthiness of the local securities firms
 used by the Underlying Fund in emerging countries may not be as sound as the
 creditworthiness of firms used in more developed countries, thus subjecting
 the Underlying Fund to a greater risk of loss if a securities firm defaults
 in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make an Underlying Fund's investments in such countries less liq-
 uid and more volatile than investments in countries with more developed
 securities markets (such as the United States, Japan and most Western Euro-
 pean countries). An Underlying Fund's investments in emerging countries are
 subject to the risk that the liquidity of a particular investment, or
 investments generally, in such countries will shrink or disappear suddenly
 and without warning as a result of adverse economic, market or political
 conditions, or adverse investor perceptions, whether or not accurate.
 Because of the lack of sufficient market liquidity, an Underlying Fund may
 incur losses because it will be required to effect sales at a disadvanta-
 geous time
 
                                                                           13-NN
<PAGE>
 
 
 and only then at a substantial drop in price. Investments in emerging coun-
 tries may be more difficult to price precisely because of their characteris-
 tics and lower trading volumes.
 
 An Underlying Fund's use of foreign currency management techniques in emerg-
 ing countries may be limited. Due to the limited market for these instru-
 ments in emerging countries, the Investment Adviser does not currently
 anticipate that a significant portion of the Funds' currency exposure in
 emerging countries, if any, will be covered by such instruments.
 
 Risks of Illiquid Securities. The Underlying Funds may invest up to 15% (10%
 in the case of the Financial Square Prime Obligations Fund) of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
  ^Both domestic and foreign securities that are not readily marketable
  ^Certain municipal leases and participation interests
  ^Certain stripped mortgage-backed securities
  ^Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  ^Certain over-the-counter options
  ^Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that
   the restricted security is eligible for resale pursuant to Rule 144A
   under the Securities Act of 1933 ("144A Securities") and, therefore, is
   liquid
 
 Investing in 144A Securities may decrease the liquidity of an Underlying
 Fund's portfolio to the extent that qualified institutional buyers become
 for a time uninterested in purchasing these restricted securities. The pur-
 chase price and subsequent valuation of restricted and illiquid securities
 normally reflect a discount, which may be significant, from the market price
 of comparable securities for which a liquid market exists.
 
 Risks of Non-Diversification and Concentration. The Global Income Fund is
 registered as a "non-diversified" Fund under the 1940 Act and is, therefore,
 more susceptible to adverse developments affecting any single issuer. In
 addition, the Global Income Fund, and certain other Underlying Funds, may
 invest more than 25% of their total assets in the securities of corporate
 and governmental issuers located in a particular foreign country or region.
 Concentration of a Fund's investments in such issuers will subject the Fund,
 to a greater extent than if investment was more limited, to the risks of
 adverse securities markets, exchange rates and social, political or economic
 events which may occur in that country or region.

 Temporary Investment Risks. Each Underlying Fund (other than the CORE Funds)
 may invest up to 100% of its total assets, and each CORE Fund may invest up
 to 35% of its total assets, in short-term debt securities. When an Under-
 lying Fund's assets are invested in such instruments, the Underlying Fund
 may not be achieving its investment objective.
 
 D. Investment Securities and Techniques
 
 U.S. Government Securities. The Underlying Funds may invest in U.S. Govern-
 ment Securities. Generally, these securities include U.S. Treasury obliga-
 tions and obligations issued or guaranteed by U.S. government agencies,
 instrumentalities or sponsored enterprises. U.S. Government Securities also
 include Treasury receipts and U.S. Government Securities that have been
 stripped by the U.S. Government, where the interest and principal components
 of the securities are traded independently. Interests in U.S. Government
 Securities may be purchased in the form of custodial receipts.
 
 Mortgage-Backed Securities. The Underlying Funds (other than the five CORE
 Equity Funds) may invest in so-called "Mortgage-Backed Securities." These
 securities represent direct or indirect participations in, or are collater-
 alized by and payable from, mortgage loans secured by real property.
 Mortgage-Backed Securities can be backed by either fixed rate mortgage loans
 or adjustable rate mortgage loans, and may be issued by either a governmen-
 tal or non-governmental entity. Privately issued Mortgage-Backed Securities
 are normally structured with one or more types of "credit enhancement." How-
 ever, these Mortgage-Backed Securities typically do not have the same credit
 standing as U.S. government guaranteed Mortgage-Backed Securities.
 
 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs"), real estate mortgage invest-
 ment conduit ("REMIC") pass-through or participation certificates and
 stripped mortgage-backed securities ("SMBS"). CMOs provide an investor with
 a specified interest in the cash flow from a pool of underlying mortgages or
 of other Mortgage-Backed Securities. CMOs are issued in multiple classes. In
 most cases, payments of principal are applied to the CMO classes in the
 order of their respective stated maturities, so that no principal payments
 will be made on a CMO class until all other classes having an earlier stated
 maturity date are paid in full. A REMIC is a CMO that qualifies for special
 tax treatment and invests in certain mortgages principally secured by inter-
 ests in real property and other permitted investments. SMBS are derivative
 multiple class Mortgage-Backed Securities. The market value of SMBS consist-
 ing entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage
 
                                                                           15-NN

 loans 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.
 
 Asset-Backed Securities. The Underlying Funds (other than the five CORE
 Equity Funds) may also invest in asset-backed securities. Certain Funds'
 Asset-Backed securities are limited to securities that are issued or guaran-
 teed by U.S. government agencies, instrumentalities or sponsored enter-
 prises. Asset-backed securities are securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed securities are often subject to more rapid repayment than their
 stated maturity date would indicate as a result of the pass-through of pre-
 payments of principal on the underlying loans. During periods of declining
 interest rates, prepayment of loans underlying asset-backed securities can
 be expected to accelerate. Accordingly, an Underlying Fund's ability to
 maintain positions in such securities will be affected by reductions in the
 principal amount of such securities resulting from prepayments, and its
 ability to reinvest the returns of principal at comparable yields is subject
 to generally prevailing interest rates at that time. Asset-backed securities
 present credit risks that are not presented by Mortgage-Backed Securities.
 This is because asset-backed securities generally do not have the benefit of
 a security interest in collateral that is comparable in quality to mortgage
 assets. There is the possibility that, in some cases, recoveries on
 repossessed collateral may not be available to support payments on these
 securities. In the event of a default, an Underlying Fund may suffer a loss
 if it cannot sell collateral quickly and receive the amount it is owed.
 
 Municipal Securities. Certain Underlying Funds may make limited investments
 in instruments issued by state and local governmental issuers. These securi-
 ties may include private activity bonds, municipal leases, certificates of
 participation and "auction rate" securities.
 
 Corporate Debt Obligations; Trust Preferred Securities; Convertible Securi-
 ties. The Underlying Funds may invest in corporate debt obligations, trust
 preferred securities and convertible securities. Corporate debt obligations
 include bonds, notes, debentures and other obligations of corporations to
 pay interest and repay principal, and include securities issued by banks and
 other financial institutions. A trust preferred or capital security is a
 long dated bond (for example, 30 years) with preferred features. The pre-
 ferred features are that payment of interest can be deferred for a specified
 period without initiating a default event. The securities are generally
 senior in claim to standard preferred stock but junior to other bondholders.

 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than nonconvertible securities of similar quali-
 ty. Convertible securities in which an Underlying Fund invests are subject
 to the same rating criteria as its other investments in fixed-income securi-
 ties. Convertible securities have both equity and fixed-income risk charac-
 teristics. Like all fixed-income securities, the value of convertible secu-
 rities is susceptible to the risk of market losses attributable to changes
 in interest rates. Generally, the market value of convertible securities
 tends to decline as interest rates increase and, conversely, to increase as
 interest rates decline. However, when the market price of the common stock
 underlying a convertible security exceeds the conversion price of the con-
 vertible security, the convertible security tends to reflect the market
 price of the underlying common stock. As the market price of the underlying
 common stock declines, the convertible security, like a fixed-income securi-
 ty, tends to trade increasingly on a yield basis, and thus may not decline
 in price to the same extent as the underlying common stock.
 
 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Each Underlying Fund may invest in zero coupon, deferred interest, pay-in-
 kind and capital appreciation bonds. These securities are issued at a dis-
 count from their face value because interest payments are typically post-
 poned until maturity. Pay-in-kind securities are securities that have
 interest payable by the delivery of additional securities.The market prices
 of these securities generally are more volatile than the market prices of
 interest-bearing securities and are likely to respond to a greater degree to
 changes in interest rates than interest-bearing securities having similar
 maturities and credit quality.
 
 Rating Criteria. The rating requirements for each of the Underlying Fixed-
 Income Funds are stated above. Except as noted below, the Underlying Equity
 Funds (other than the five CORE Equity Funds, which only invest in debt
 instruments that are cash equivalents) may invest in debt securities rated
 at least investment grade at the time of investment. Investment grade debt
 securities are securities rated BBB or higher by Standard & Poor's or Baa or
 higher by Moody's. The Growth and Income, Capital Growth, Small Cap Value,
 International Equity, Japanese Equity, European Equity, International Small
 Cap, Emerging Markets Equity, Asia Growth and Real Estate Securities Funds
 may invest up to 10%, 10%, 35%, 35%, 35%, 35%, 35%, 35%, 35% and 20%,
 respectively, of their total assets in debt securities which are rated in
 the lowest rating categories by Standard & Poor's or Moody's (i.e., BB or
 lower by Standard & Poor's or Ba or lower by Moody's), including securities
 rated D by Moody's or Standard & Poor's. The Mid Cap Value Fund may invest
 up to 10% of its total assets in below investment grade debt securities
 rated B or higher by Standard & Poor's or Moody's. Fixed-
 
                                                                           17-NN

 income securities rated BB or Ba or below (or comparable unrated securities)
 are commonly referred to as "junk bonds," are considered predominately spec-
 ulative and may be questionable as to principal and interest payments as
 described above.
 
 Structured Securities and Inverse Floaters. The Underlying Funds may invest
 in structured securities. Structured securities are securities whose value
 is determined by reference to changes in the value of specific currencies,
 interest rates, commodities, indices or other financial indicators (the
 "Reference") or the relative change in two or more References. The interest
 rate or the principal amount payable upon maturity or redemption may be
 increased or decreased depending upon changes in the applicable Reference.
 Structured securities may be positively or negatively indexed, so that
 appreciation of the Reference may produce an increase or decrease in the
 interest rate or value of the security at maturity. In addition, changes in
 the interest rates or the value of the security at maturity may be a multi-
 ple of changes in the value of the Reference. Consequently, structured secu-
 rities may present a greater degree of market risk than other types of
 fixed-income securities, and may be more volatile, less liquid and more dif-
 ficult to price accurately than less complex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.
 
 Foreign Currency Transactions. The Underlying Funds may, to the extent con-
 sistent with its investment policies, purchase or sell foreign currencies on
 a cash basis or through forward contracts. A forward contract involves an
 obligation to purchase or sell a specific currency at a future date at a
 price set at the time of the contract. A Fund may engage in foreign currency
 transactions for hedging purposes and to seek to protect against anticipated
 changes in future foreign currency exchange rates. In addition, certain
 Underlying Funds may also enter into such transactions to seek to increase
 total return, which is considered a speculative practice. Some Funds may
 also engage in cross-hedging by using forward contracts in a currency dif-
 ferent from that in which the hedged security is denominated or quoted if
 the investment adviser determines that there is a pattern of correlation
 between the two currencies. The Underlying Funds may hold foreign currency
 received in connection with investments in foreign securities when, in the
 judgment of its investment adviser, it would be beneficial to convert such
 currency into U.S. dollars at a later date.

 Currency exchange rates may fluctuate significantly over short periods of
 time causing, along with other factors, an Underlying Fund's value to fluc-
 tuate. Currency exchange rates also can be affected unpredictably by the
 intervention of U.S. or foreign governments or central banks, or the failure
 to intervene, or by currency controls or political developments in the
 United States or abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are not guaranteed by an exchange or clear-
 inghouse, a default on a contract would deprive an Underlying Fund of
 unrealized profits, or the benefits of a currency hedge, or could force the
 Underlying Fund to cover its purchase or sale commitments, if any, at the
 current market price.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Underlying Fund
 (other than the CORE U.S. Equity, CORE Large Cap Growth and CORE Large Cap
 Value Funds) may write (sell) covered call and put options and purchase put
 and call options on any securities in which it may invest or on any securi-
 ties index comprised of securities in which it may invest. An Underlying
 Fund, may also, to the extent it invests in foreign securities, purchase and
 sell (write) put and call options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of an investment adviser to manage future price fluctua-
 tions and the degree of correlation between the options and securities (or
 currency) markets. If an investment adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in an Underlying Fund's investment portfolio, the Underlying
 Fund may incur losses that it would not otherwise incur. The use of options
 can also increase an Underlying Fund's transaction costs. Options written or
 purchased by the Underlying Funds may be traded on either U.S. or foreign
 exchanges or over-the-counter. Foreign and over-the-counter options will
 present greater possibility of loss because of their greater liquidity and
 credit risks.

 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. The Underlying Funds may engage in
 futures transactions on both U.S. and foreign exchanges.
 
 The Underlying Funds may purchase and sell futures contracts, and purchase
 and write call and put options on futures contracts, in order to seek to
 increase total return or to hedge against changes in interest rates, securi-
 ties prices or currency exchange rates, or to otherwise manage their term
 structures and durations in accordance with their investment objectives and
 policies. The Underlying Funds may also enter into closing purchase and sale
 transactions with respect to such contracts and options. An Underlying Fund
 will engage in futures and related options transactions for bona fide hedg-
 ing purposes as defined in regulations of the Commodity Futures Trading Com-
 mission or to seek to increase total return to the extent permitted by such
 regulations. The Underlying Funds may not purchase or sell futures contracts
 or purchase or sell related options to seek to increase total return, except
 for closing purchase or sale transactions, if immediately thereafter the sum
 of the amount of initial margin deposits and premiums paid on an Underlying
 Fund's outstanding positions in futures and related options entered into for
 the purpose of seeking to increase total return would exceed 5% of the mar-
 ket value of an Underlying Fund's net assets. Futures contracts and related
 options present the following risks:
 
^While an Underlying Fund may benefit from the use of futures and options on
 futures, unanticipated changes in interest rates, securities prices or cur-
 rency exchange rates may result in a poorer overall performance than if the
 Fund had not entered into any futures contracts or options transactions.
 
^Because perfect correlation between a futures position and portfolio position
 that is intended to be protected is impossible to achieve, the desired pro-
 tection may not be obtained and an Underlying Fund may be exposed to addi-
 tional risk of loss.
 
^The loss incurred by an Underlying Fund in entering into futures contracts
 and in writing call options on futures is potentially unlimited and may
 exceed the amount of the premium received.

^Futures markets are highly volatile and the use of futures may increase the
 volatility of an Underlying Fund's NAV.
 
^As a result of the low margin deposits normally required in futures trading,
 a relatively small price movement in a futures contract may result in sub-
 stantial losses to an Underlying Fund.
 
^Futures contracts and options on futures may be illiquid, and exchanges may
 limit fluctuations in futures contract prices during a single day.
 
 ^Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 Preferred Stock, Warrants and Rights. The Underlying Funds may invest in
 preferred stock, warrants and rights. Preferred stocks are securities that
 represent an ownership interest providing the holder with claims on the
 issuer's earnings and assets before common stock owners but after bond own-
 ers. Unlike debt securities, the obligations of an issuer of preferred
 stock, including dividend and other payment obligations, may not typically
 be accelerated by the holders of such preferred stock on the occurrence of
 an event of default or other non-compliance by the issuer of the preferred
 stock. Warrants and other rights are options to buy a stated number of
 shares of common stock at a specified price at any time during the life of
 the warrant. The holders of warrants and rights have no voting rights,
 receive no dividends and have no rights with respect to the assets of the
 issuer.
 
 Real Estate Investment Trusts ("REITs"). The Real Estate Securities Fund
 expects to invest a substantial portion of its total assets in REITs, which
 are pooled investment vehicles that invest primarily in either real estate
 or real estate related loans. In addition, other Underlying Equity Funds may
 invest in REITs from time to time. The value of a REIT is affected by
 changes in the value of the properties owned by the REIT or securing mort-
 gage loans held by the REIT. REITs are dependent upon the ability of the
 REITs' managers, and are subject to heavy cash flow dependency, default by
 borrowers and the qualification of the REITs under applicable regulatory
 requirements for favorable federal income tax treatment. REITs are also sub-
 ject to risks generally associated with investments in real estate including
 possible declines in the value of real estate, general and local economic
 conditions, environmental problems and changes in interest rates. To the
 extent that assets underlying a REIT are concentrated geographically, by
 property type or in certain other respects, these risks may be heightened.
 Each Underlying Fund will indirectly bear its proportionate share of any
 expenses, including management fees, paid by a REIT in which it invests.
 
 Standard and Poor's Depository Receipts. Each Underlying Equity Fund may,
 consistent with its investment policies, purchase Standard & Poor's Deposi-
 tory
 
                                                                           21-NN
<PAGE>
 
 
 Receipts ("SPDRs"). SPDRs are American Stock Exchange-traded securities that
 represent ownership in the SPDR Trust, a trust which has been established to
 accumulate and hold a portfolio of common stocks that is intended to track
 the price performance and dividend yield of the S&P 500. The SPDR Trust is
 sponsored by a subsidiary of the American Stock Exchange. SPDRs may be used
 for several reasons, including, but not limited to, facilitating the han-
 dling of cash flows or trading or reducing transaction costs. The price
 movement of SPDRs may not perfectly parallel the price action of the S&P
 500.
 
 World Equity Benchmark Shares. World Equity Benchmark Shares ("WEBS") are
 shares of an investment company that invests substantially all of its assets
 in securities included in the MSCI indices for specified countries. WEBS are
 listed on the American Stock Exchange (the "AMEX"), and were initially
 offered to the public in 1996. The market prices of WEBS are expected to
 fluctuate in accordance with both changes in the net asset values of their
 underlying indices and supply and demand of WEBS on the AMEX. To date, WEBS
 have traded at relatively modest discounts and premiums to their net asset
 values. However, WEBS have a limited operating history, and information is
 lacking regarding the actual performance and trading liquidity of WEBS for
 extended periods or over complete market cycles. In addition, there is no
 assurance that the requirements of the AMEX necessary to maintain the list-
 ing of WEBS will continue to be met or will remain unchanged. In the event
 substantial market or other disruptions affecting WEBS should occur in the
 future, the liquidity and value of an Underlying Fund's shares could also be
 substantially and adversely affected, and the Underlying Fund's ability to
 provide investment results approximating the performance of securities in
 the EAFE Index could be impaired. If such disruptions were to occur, an
 Underlying Fund could be required to reconsider the use of WEBS as part of
 its investment strategy.
 
 Other Investment Companies. An Underlying Fund may invest in securities of
 other investment companies subject to the limitations prescribed by the
 Investment Company Act. These limitations include a prohibition on any Fund
 acquiring more than 3% of the voting shares of any other investment company,
 and a prohibition on investing more than 5% of an Underlying Fund's total
 assets in securities of any one investment company or more than 10% of its
 total assets in securities of all investment companies. An Underlying Fund
 will indirectly bear its proportionate share of any management fees and
 other expenses paid by such other investment companies. Such other invest-
 ment companies will have investment objectives, policies and restrictions
 substantially similar to those of the acquiring Fund and will be subject to
 substantially the same risks.
 
 Equity Swaps. Each Underlying Equity Fund may invest up to 10% of its total
 assets in equity swaps. Equity swaps allow the parties to a swap agreement
 to

                                                                      APPENDIX A
 
 exchange the dividend income or other components of return on an equity
 investment (e.g., a group of equity securities or an index) for a component
 of return on another non-equity or equity investment.
 
 An equity swap may be used by an Underlying Fund to invest in a market with-
 out owning or taking physical custody of securities in circumstances in
 which direct investment may be restricted for legal reasons or is otherwise
 impractical. Equity swaps are derivatives and their value can be very vola-
 tile. To the extent that an investment adviser does not accurately analyze
 and predict the potential relative fluctuation of the components swapped
 with another party, an Underlying Fund may suffer a loss. The value of some
 components of an equity swap (such as the dividends on a common stock) may
 also be sensitive to changes in interest rates. Furthermore, an Underlying
 Fund may suffer a loss if the counterparty defaults.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to an Underlying Fund at the time of entering into the
 transaction. A forward commitment involves the entering into a contract to
 purchase or sell securities for a fixed price at a future date beyond the
 customary settlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although an Underlying Fund
 will generally purchase securities on a when-issued or forward commitment
 basis with the intention of acquiring securities for its portfolio, an
 Underlying Fund may dispose of when-issued securities or forward commitments
 before settlement whenever its investment adviser deems it appropriate.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Underlying Fund may enter into repurchase
 agreements with dealers in U.S. Government Securities and member banks of
 the Federal Reserve System which furnish collateral at least equal in value
 or market price to the amount of their repurchase obligation. Some Under-
 lying Funds may also enter into repurchase agreements involving certain for-
 eign government securities. If the other party or "seller" defaults, an
 Underlying Fund might suffer a loss to the extent that the proceeds from the
 sale of the underlying securities and other collateral held by the Under-
 lying Fund in connection with the repurchase agreements are less than the
 repurchase price and the cost of the Underlying Fund associated with delay
 and enforcement of the repurchase agreement. In addition, in the event of
 
                                                                           23-NN
<PAGE>
 
 
 bankruptcy of the seller, an Underlying Fund could suffer additional losses
 if a court determines that the Underlying Fund's interest in the collateral
 is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to an
 Underlying Fund's shareholders. In addition, certain Underlying Funds,
 together with other registered investment companies having advisory agree-
 ments with the Investment Adviser or any of its affiliates, may transfer
 uninvested cash balances into a single joint account, the daily aggregate
 balance of which will be invested in one or more repurchase agreements.
 
 Lending of Portfolio Securities. Securities lending involves the lending of
 securities owned by an Underlying Fund to financial institutions such as
 certain broker-dealers. The borrowers are required to secure their loans
 continuously with cash, cash equivalents, U.S. Government Securities or let-
 ters of credit in an amount at least equal to the market value of the secu-
 rities loaned. Cash collateral may be invested in cash equivalents. If an
 investment adviser determines to make securities loans, the value of the
 securities loaned may not exceed 33 1/3% of the value of the total assets of
 an Underlying Fund (including the loan collateral).
 
 An Underlying Fund may lend its securities to increase its income. An Under-
 lying Fund may, however, experience delay in the recovery of its securities
 or possible loss if the institution with which it has engaged in a portfolio
 loan transaction breaches its agreement with the Underlying Fund.
 
 Short Sales Against-the-Box. Certain Underlying Funds may make short sales
 against-the-box. A short sale against-the-box means that at all times when a
 short position is open the Underlying Fund will own an equal amount of secu-
 rities sold short, or securities convertible into or exchangeable for, with-
 out the payment of any further consideration, an equal amount of the securi-
 ties of the same issuer as the securities sold short.
 
 Mortgage Dollar Rolls. The Underlying Fixed-Income Funds (except the High
 Yield Fund) and the Real Estate Securities Fund may enter into "mortgage
 dollar rolls." A mortgage dollar roll involves the sale by an Underlying
 Fund of securities for delivery in the current month, simultaneously con-
 tracts with the same counterparty to repurchase substantially similar (same
 type, coupon and maturity) but not identical securities on a specified
 future date. During the roll period, the Underlying Fund loses the right to
 receive principal and interest paid on the securities sold. However, the
 Underlying Fund benefits to the extent of any difference between (a) the
 price received for the securities sold and (b) the lower forward price for
 the future purchase and/or fee income plus the interest earned on the

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

 Underlying Funds may engage in the following techniques and investments: (i)
 yield curve options (Underlying Fixed-Income Funds and Real Estate Securi-
 ties Fund only); (ii) loan participations (High Yield Fund only); and (iii)
 unseasoned companies.

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

General Investment
Management Approach
 
Goldman Sachs Asset Management, a separate operating division of Goldman, Sachs
& Co. ("Goldman Sachs"), serves as investment adviser (the "Investment Advis-
er") to five asset allocation portfolios: the Conservative Strategy Portfolio,
Balanced Strategy Portfolio (formerly, the Income Strategy Portfolio), Growth
and Income Strategy Portfolio, Growth Strategy Portfolio and Aggressive Growth
Strategy Portfolio (referred to as the "Portfolios" or the "Funds" interchange-
ably herein). The Portfolios are intended for investors who prefer to have
their asset allocation decisions made by professional money managers. Each
Portfolio seeks to achieve its objectives by investing in a combination of
underlying funds for which Goldman Sachs now or in the future acts as invest-
ment adviser or principal underwriter (the "Underlying Funds"). Some of these
Funds invest primarily in fixed-income or money market securities (the "Under-
lying Fixed-Income Funds"); other Funds invest primarily in equity securities
(the "Underlying Equity Funds"). You may choose to invest in one or more of the
Portfolios based on your personal investment goals, risk tolerance, and finan-
cial circumstances.
 
Goldman Sachs' Asset Allocation Investment Philosophy
The Investment Adviser's Quantitative Research Group uses disciplined quantita-
tive models to determine the relative attractiveness of the world's stock, bond
and currency markets. These models use financial and economic variables to cap-
ture fundamental relationships that it believes make sense. While the Invest-
ment Adviser's process is rigorous and quantitative, it also incorporates clear
economic reasoning behind each recommendation.
 
Each Portfolio starts with a "base-line" or strategic allocation among the var-
ious asset classes. The Investment Adviser then tactically deviates from the
strategic allocations based on forecasts provided by the models. The tactical
process seeks to add value by overweighing attractive markets and underweighing
unattractive markets. Greater deviations from the strategic allocation of a
given Portfolio result in higher risk that the tactical allocation will
underperform the strategic allocation. However, the Investment Adviser's risk
control process balances the amount any asset class can be overweighed in seek-
ing to achieve higher expected returns
 
 The Asset Allocation Investment Philosophy involves investing a Portfolio's
 assets in other Goldman Sachs Funds within specified equity and fixed-income
 percentage ranges.

 against the amount of risk imposed by that deviation from the strategic
 allocation. The Investment Adviser employs Goldman Sachs' proprietary Black-
 Litterman asset allocation technique in an effort to optimally balance these
 two goals. This technique combines the Quantitative Research Group's market
 forecast with economic equilibrium in seeking to construct risk-controlled
 portfolios.

Portfolio Investment Objectives and Strategies
 
 Goldman Sachs Conservative Strategy Portfolio
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income, consistent with the preservation of cap-
 ital and secondarily also considers the potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 80% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds, with a focus on
 short-term investments including money market funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its assets in
 the Global Income Fund, Financial Square Prime Obligations Fund and CORE
 Large Cap Value Fund. It is expected that the Portfolio will invest more
 than 25% of its assets in the Short Duration Government Fund. The Portfolio
 may not invest in International Underlying Equity Funds.

Goldman Sachs Balanced Strategy Portfolio
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income and long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 60% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its equity
 allocation in the CORE Large Cap Growth, CORE Large Cap Value and CORE
 International Equity Funds and will invest a relatively significant percent-
 age of its assets in the Global Income Fund. It is expected that the Portfo-
 lio will invest more than 25% of its assets in the Short Duration Government
 Fund.

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

 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 80% of the Portfolio's total assets
 will be allocated among Underlying Equity Funds, with a blend of domestic
 large cap, small cap and international exposure to seek capital apprecia-

 diversification. The Investment Adviser expects that the Portfolio will
 invest a relatively significant percentage of its equity allocation in the
 CORE Large Cap Growth, CORE Large Cap Value and CORE International Equity

 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, substantially all of the Portfolio's total assets
 will be allocated among Underlying Equity Funds, with a greater focus on
 small cap and international investments. The Investment Adviser expects that
 the Portfolio will invest a relatively significant percentage of its assets
 in the CORE Large Cap Growth, CORE Large Cap Value and CORE International
 Equity Funds.

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

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

                                                 PRINCIPAL INVESTMENT STRATEGIES
 
 
 While each Portfolio can invest in any or all of the Underlying Funds, it is
 expected that each Portfolio will normally invest in only some of the Under-
 lying Funds at any particular time. Each Portfolio's investment in any of
 the Underlying Funds may, and in some cases is expected to, exceed 25% of
 such Portfolio's total assets.
 
 THE PARTICULAR UNDERLYING FUNDS IN WHICH EACH PORTFOLIO MAY INVEST, THE
 EQUITY/FIXED INCOME TARGETS AND RANGES AND THE INVESTMENTS IN EACH UNDER-
 LYING FUND MAY BE CHANGED FROM TIME TO TIME WITHOUT SHAREHOLDER APPROVAL.

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

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

Principal Risks of the Underlying Funds
 
The following summarizes important risks that apply to the Underlying Funds and
may result in a loss of your investment in a Portfolio. There can be no assur-
ance that an Underlying Fund will achieve its investment objective.
 
Risks That Apply To All Underlying Funds:
 
 ^Market Risk--The risk that the value of the securities in which an Under-
  lying Fund invests may go up or down in response to the prospects of indi-
  vidual companies and/or general economic conditions. Price changes may be
  temporary or last for extended periods.
 ^Derivatives Risk--The risk that loss may result from an Underlying Fund's
  investments in options, futures, swaps, structured securities and other
  derivative instruments, which may be leveraged.
 ^Management Risk--The risk that a strategy used by an investment adviser to
  the Underlying Funds may fail to produce the intended results.
 ^Liquidity Risk--The risk that an Underlying Fund will not be able to pay
  redemption proceeds within the time period stated in this Prospectus,
  because of unusual market conditions, an unusually high volume of redemp-
  tion requests, or other reasons. Funds that invest in small capitalization
  stocks, REITs and emerging country issuers will be especially subject to
  the risk that during certain periods the liquidity of particular issuers or
  industries, or all securities within these investment categories, will
  shrink or disappear suddenly and without warning as a result of adverse
  economic, market or political events, or adverse investor perceptions,
  whether or not accurate.
 ^Other Risks--Each Underlying Fund is subject to other risks, such as the
  risk that its operations, or the value of its portfolio securities, will be
  disrupted by the "Year 2000 Problem."
 
Risks That Apply Primarily To The Underlying Fixed-Income Funds:
 
 ^Interest Rate Risk--The risk that when interest rates increase, fixed-
  income securities held by an Underlying Fund will decline in value. Long-
  term fixed-income securities will normally have more price volatility
  because of this risk than short-term securities.
 ^Credit/Default Risk--The risk that an issuer of fixed-income securities
  held by an Underlying Fund (which may have low credit ratings) may default
  on its obligation to pay interest and repay principal.
 ^Call Risk--The risk that an issuer will exercise its right to pay principal
  on an obligation held by an Underlying Fund (such as a mortgage-backed secu-
 
                                                                            17-Z

  rity) earlier than expected. This may happen when there is a decline in
  interest rates. Under these circumstances, an Underlying Fund may be unable
  to recoup all of its initial investment and will also suffer from having to
  reinvest in lower yielding securities.
 ^Extension Risk--The risk that an issuer will exercise its right to pay
  principal on an obligation held by an Underlying Fund (such as a mortgage-
  backed security) later than expected. This may happen when there is a rise
  in interest rates. Under these circumstances, the value of an obligation
  will decrease, and an Underlying Fund will also suffer from the inability
  to invest in higher yielding securities.
 ^Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risk That Applies Primarily To The Underlying Equity Funds:
 
 ^Stock Risk--The risk that stock prices have historically risen and fallen
  in periodic cycles. As of the date of this Prospectus, U.S. stock markets
  and certain foreign stock markets were trading at or close to record high
  levels. There is no guarantee that such levels will continue.
 
Risks That Are Particularly Important For Specific Underlying Funds:
 
 ^Concentration Risk--The European Equity Fund invests primarily in equity
  securities of European companies. The Japanese Equity Fund invests primar-
  ily in equity securities of Japanese companies. The Global Income Fund may
  invest more than 25% of its total assets in the securities of corporate and
  governmental issuers located in each of Canada, Germany, Japan, and the
  United Kingdom as well as in the securities of U.S. issuers. Concentration
  of the investments of these or other Underlying Funds in issuers located in
  a particular country or region will subject the Underlying Fund, to a
  greater extent than if investments were not so concentrated, to the risks
  of adverse securities markets, exchange rates and social, political, regu-
  latory or economic events which may occur in that country or region.
 ^Foreign Risks--Underlying Funds that invest in foreign securities will be
  subject to risks with respect to their foreign investments that are not
  typically associated with domestic issuers. These risks result from less
  government regulation, less public information and less economic, political
  and social stability. These risks may involve the imposition of exchange
  controls, confiscation and other government restrictions. The Underlying
  Funds will also be subject to the risk of negative foreign currency rate
  fluctuations. Foreign risks will normally be greatest when an Underlying
  Fund invests in issuers located in emerging countries.

                                         PRINCIPAL RISKS OF THE UNDERLYING FUNDS
 
 ^Emerging Markets Risk--The securities markets of Asian, Latin American,
  Eastern European, African and other emerging countries are less liquid, are
  especially subject to greater price volatility, have smaller market capi-
  talizations, have less government regulation and are not subject to as
  extensive and frequent accounting, financial and other reporting require-
  ments as the securities markets of more developed countries. Further,
  investment in equity securities of issuers located in Russia and certain
  other emerging countries involves risk of loss resulting from problems in
  share registration and custody and substantial economic and political dis-
  ruptions. These risks are not normally associated with investments in more
  developed countries.
 ^"Junk Bond" Risk--The High Yield Fund will invest in non-investment grade
  fixed-income securities (commonly known as "junk bonds") that are consid-
  ered predominantly speculative by traditional investment standards. Non-
  investment grade fixed-income securities and unrated securities of compara-
  ble credit quality are subject to the increased risk of an issuer's
  inability to meet principal and interest payment obligations. These securi-
  ties may be subject to greater price volatility due to such factors as spe-
  cific corporate developments, interest rate sensitivity, negative percep-
  tions of the junk bond markets generally and less secondary market
  liquidity.
 ^Small Cap Stock and REIT Risks--The securities of small capitalization com-
  panies and REITs involve greater risks than those associated with larger,
  more established companies, and the securities may be subject to more
  abrupt or erratic price movements. Securities of such issuers may lack suf-
  ficient market liquidity to enable an Underlying Fund to effect sales at an
  advantageous time or without a substantial drop in price.
 
More information about the portfolio securities and investment techniques of
the Underlying Funds, and their associated risks, is provided in Appendix A.
You should consider the investment risks discussed in this section and in
Appendix A. Both are important to your investment choice.

Portfolio Performance
 
 HOW THE PORTFOLIOS HAVE PERFORMED
 
 
 The bar charts and tables below provide an indication of the risks of
 investing in a Portfolio by showing: (a) changes in the performance of a
 Portfolio's Institutional Shares from year to year; and (b) how the average
 annual returns of a Portfolio's Institutional Shares compare to those of a
 broad-based securities market index. The bar charts and tables assume rein-
 vestment of dividends and distributions. A Portfolio's past performance is
 not necessarily an indication of how the Portfolio will perform in the
 future. Performance reflects expense limitations in effect. If expense limi-
 tations were not in place, a Portfolio's performance would have been
 reduced. The Conservative Strategy Portfolio did not commence until February
 8, 1999. Since the Portfolio has less than one calendar year's performance,
 no performance information is provided in this section.

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

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

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

 future at its discretion.

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

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

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

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

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

Shareholder Guide
 
 The following section will provide you with answers to some of the most
 often asked questions regarding buying and selling the Funds' Institutional
 Shares.
 
 HOW TO BUY SHARES
 
 
 How Can I Purchase Institutional Shares Of The Funds?

 You may purchase Institutional Shares on any business day at their NAV next
 determined after receipt of an order. No sales load is charged. You should
 place an order with Goldman Sachs at 1-800-621-2550 and either:

..  Wire federal funds to State Street Bank and Trust Company ("State Street")
    (each Fund's custodian) on the next business day; or

..  Initiate an Automated Clearing House Network ("ACH") transfer; or

..  Send a check or Federal Reserve draft payable to Goldman Sachs Funds--(Name
    of Fund and Class of Shares), 4900 Sears Tower--60th Floor, Chicago, IL
    60606-6372. Goldman Sachs Trust (the "Trust") will not accept a check drawn
    on a foreign bank or a third-party check.
 
 In order to make an initial investment in a Fund, you must furnish to the
 Fund or Goldman Sachs the Account Application attached to this Prospectus.
 Purchases of Institutional Shares must be settled within three business days
 of receipt of a complete purchase order.
 
 How Do I Purchase Shares Through a Financial Institution?

 Certain institutions (including banks, trust companies, brokers and invest-
 ment advisers) that provide recordkeeping, reporting and processing services
 to their customers may be authorized to accept, on behalf of the Trust, pur-
 chase, redemption and exchange orders placed by or on behalf of their cus-
 tomers, and may designate other intermediaries to accept such orders, if
 approved by the Trust. In these cases:

..  A Fund will be deemed to have received an order in proper form when the
    order is accepted by the authorized institution or intermediary on a busi-
    ness day, and the order will be priced at the Fund's NAV next determined
    after such acceptance.

..  Authorized institutions and intermediaries will be responsible for trans-
    mitting accepted orders and payments to the Trust within the time period
    agreed upon by them.

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

</TABLE>
 The minimum investment requirement may be waived for current and former
 officers, partners, directors or employees of Goldman Sachs or any of its
 affiliates or for other investors at the discretion of the Trust's officers.
 No minimum amount is required for subsequent investments.
 
 What Else Should I Know About Share Purchases?
 The Trust reserves the right to:
.. Modify or waive the minimum investment amounts.
.. Reject or restrict any purchase or exchange orders by a particular pur-chaser
   (or group of related purchasers). This may occur, for example, when a pattern
   of frequent purchases, sales or exchanges of Institutional Shares of a Fund
   is evident, or if purchases, sales or exchanges are, or a subse-quent abrupt
   redemption might be, of a size that would disrupt the manage-ment of a Fund.
 
                                                                             3-G
<PAGE>
 
 
 
 The Funds may allow you to purchase shares with securities instead of cash
 if consistent with a Fund's investment policies and operations and if
 approved by the Fund's Investment Adviser.
 
 How Are Shares Priced?
 The price you pay or receive when you buy, sell or exchange Institutional
 Shares is determined by a Fund's NAV. The Funds calculate NAV as follows:
 
               (Value of Assets of the Class)
                - (Liabilities of the Class)
     NAV = -----------------------------------------
           Number of Outstanding Shares of the Class
 
 
 The Funds' investments are valued based on market quotations or if accurate
 quotations are not readily available, at fair value as determined in good
 faith under procedures established by the Trustees.

.. NAV per share of each class is calculated by State Street each business day
   as of the close of regular trading on the New York Stock Exchange (normally
   4:00 p.m. New York time). Fund shares will not be priced on any day the New
   York Stock Exchange is closed.

.. When you buy shares, you pay the NAV next calculated after the Funds
   receive your order in proper form.

.. When you sell shares, you receive the NAV next calculated after the Funds
   receive your order in proper form.
 
 Note: The time at which transactions and shares are priced and the time by
 which orders must be received may be changed in case of an emergency or if
 regular trading on the New York Stock Exchange is stopped at a time other
 than 4:00 p.m. New York time.
 
 Foreign securities may trade in their local markets on days a Fund is
 closed. As a result, the NAV of a Fund that holds foreign securities may be
 impacted on days when investors may not purchase or redeem Fund shares.
 
 In addition, the impact of events that occur after the publication of market
 quotations used by a Fund to price its securities but before the close of
 regular trading on the New York Stock Exchange will normally not be
 reflected in a Fund's next determined NAV unless the Trust, in its discre-
 tion, makes an adjustment in light of the nature and materiality of the
 event, its effect on Fund operations and other relevant factors.

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

 Certain institutions and intermediaries are authorized to accept redemption
 requests on behalf of the Funds as described under "How Do I Purchase Shares

 What Is A Signature Guarantee?
 A signature guarantee is designed to protect you, the Funds and Goldman
 Sachs from fraud. You may obtain a signature guarantee from a bank, securi-
 ties broker or dealer, credit union having the authority to issue signature
 guarantees, savings and loan association, building and loan association,
 cooperative bank, federal savings bank or association, national securities
 exchange, registered securities association or clearing agency, provided
 that such institution satisfies the standards established by Goldman Sachs.

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

.. All telephone requests are recorded.
.. Any redemption request that requires money to go to an account or address
   other than that designated on the Account Application must be in writing and
   signed by an authorized person designated on the Account Application. The
   written request will be confirmed by telephone with both the requesting party
   and the designated bank account to verify instructions.
.. The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: You may arrange for your redemption proceeds to be wired as federal
 funds to the bank account designated in your Account Application. The fol-
 lowing general policies govern wiring redemption proceeds:
.. Redemption proceeds will normally be wired on the next business day in fed-
   eral funds (for a total of one business day delay), but may be paid up to
   three business days following receipt of a properly executed wire transfer
   redemption request, unless you are selling shares you recently paid for by
   check. In that case, the Funds will pay you when your check has cleared,
   which may take up to 15 days. If the Federal Reserve Bank is closed on the
   day that the redemption proceeds would ordinarily be wired, wiring the
   redemption proceeds may be delayed one additional business day.
.. To change the bank designated on your Account Application, you must send
   written instructions signed by an authorized person designated on the
   account application to the Transfer Agent.
.. Neither the Trust, Goldman Sachs nor any other institution assumes any
   responsibility for the performance of your bank or any intermediaries in
   the transfer process. If a problem with such performance arises, you should
   deal directly with your bank or any such intermediaries.
.. If the redeemed shares were recently paid for by check, the Funds will pay
   the redemption proceeds when the check has cleared, which may take up to 15
   days.

 By Check: You may elect in writing to receive your redemption proceeds by
 check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of a properly executed redemp-
 tion request, unless you are selling shares you recently paid for by check.
 In that case, the Funds will pay you when your check has cleared, which may
 take up to 15 days.
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
.. Additional documentation may be required when deemed appropriate by the
   Transfer Agent. A redemption request will not be in proper form until such
   additional documentation has been received.
.. Institutions (including banks, trust companies, brokers and investment
   advisers) are responsible for the timely transmittal of redemption requests
   by their customers to the Transfer Agent. In order to facilitate the timely
   transmittal of redemption requests, these institutions may set times by
   which they must receive redemption requests. These institutions may also
   require additional documentation from you.
 
 The Trust reserves the right to:
.. Redeem your shares if your account balance falls below $50 as a result of
   earlier redemptions. The Funds will not redeem your shares on this basis if
   the value of your account falls below the minimum account balance solely as
   a result of market conditions. The Fund will give you 60 days' prior writ-
   ten notice to allow you to purchase sufficient additional shares of the
   Fund in order to avoid such redemption.
.. Redeem your shares in other circumstances determined by the Board of Trust-
   ees to be in the best interest of the Trust.
.. Pay redemptions by a distribution in-kind of securities (instead of cash).
   If you receive redemption proceeds in-kind, you should expect to incur
   transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 You may exchange Institutional Shares of a Fund at NAV for Institutional
 Shares of any other Goldman Sachs Fund. The exchange privilege may be mate-
 rially modified or withdrawn at any time upon 60 days' written notice to
 you.

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

 What Types of Reports Will I Be Sent Regarding Investments in Institutional
 Shares?
 You will receive an annual report containing audited financial statements
 and a semiannual report. To eliminate unnecessary duplication, only one copy
 of such reports will be sent to shareholders with the same mailing address.
 If you would like a duplicate copy to be mailed to you, please contact
 Goldman Sachs Funds at 1-800-621-2550. You will also be provided with a
 printed confirmation for each transaction in your account and a monthly
 account statement. A year-to-date statement for your account will be pro-
 vided upon request made to Goldman Sachs. The Funds do not generally provide
 sub-accounting services.

 Taxation
 
 TAXABILITY OF DISTRIBUTIONS
 
 
 Portfolio distributions are taxable to you as ordinary income (unless your
 investment is in an IRA or other tax-advantaged account) to the extent they
 are attributable to the Portfolio's net investment income, certain net real-
 ized foreign exchange gains and net short-term capital gains. They are tax-
 able as long-term capital gains to the extent they are attributable to the
 Portfolio's excess of net long-term capital gains (including long-term capi-
 tal gain distributions received from Underlying Fund investments) over net
 short-term capital losses. The tax status of any distribution is the same
 regardless of how long you have been in the Portfolio and whether you rein-
 vest in additional shares or take the distribution as cash. Certain distri-
 butions paid by a Portfolio in January of a given year may be taxable to
 shareholders as if received the prior December 31. The tax status and
 amounts of the dividends and distributions for each calendar year will be
 detailed in your annual tax statement from the Portfolio.
 
 The REIT investments of the underlying Real Estate Securities Fund often do
 not provide complete tax information to the Fund until after the calendar
 year-end. Consequently, because of the delay, it may be necessary for the
 Fund to request permission to extend the deadline for issuance of Forms
 1099-DIV beyond January 31.
 
 At any time, a portion of a Portfolio's NAV per share may be represented by
 undistributed income or realized or unrealized appreciation of the Under-
 lying Fund's portfolio securities. Therefore, subsequent distributions on a
 Portfolio's shares may be taxable to you, even if the NAV of your shares is,
 as a result, reduced below the cost of those shares and the distributions
 represent a return of your purchase price.
 
 A Fund's dividends that are paid to its corporate shareholders and are
 attributable to qualifying dividends the Fund receives from Underlying Fund
 investments may be eligible, in the hands of the corporate shareholders, for
 the corporate dividends-received deduction, subject to certain holding
 period requirements and debt financing limitations.
 
 There are certain tax requirements that all Portfolios must follow in order
 to avoid federal taxation. In its efforts to adhere to these requirements,
 the Funds may have to limit their investment activity in some types of
 instruments.
 
                                                                            1-NN

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

Appendix A
 
Additional Information on the Underlying Funds
 This Appendix provides further information on certain types of securities
 and techniques that may be used by the Underlying Funds, including their
 associated risks. Additional information is provided in the Additional
 Statement, which is available upon request, and in the prospectuses of the
 Underlying Funds.
 
 The Underlying Equity Funds invest primarily in common stocks and other
 equity securities, including preferred stocks, interests in real estate
 investment trusts, convertible debt obligations, convertible preferred
 stocks, equity interests in trusts, partnerships, joint ventures, limited
 liability companies and similar enterprises, warrants and stock purchase
 rights ("equity securities"). The Underlying Fixed-Income Funds invest pri-
 marily in fixed-income securities, including senior and subordinated corpo-
 rate debt obligations (such as bonds, debentures, notes and commercial
 paper), convertible and non-convertible corporate debt obligations, loan
 participations and preferred stock.
 
 The Short Duration Government and Adjustable Rate Government Funds invest in
 U.S. Government Securities and related repurchase agreements, and neither of
 these Funds, the Government Income Fund nor the Financial Square Prime Obli-
 gations Fund makes foreign investments. The investments of the Financial
 Square Prime Obligations Fund are limited by SEC regulations applicable to
 money market funds as described in its prospectus, and do not include many
 of the types of investments discussed below that are permitted for the other
 Underlying Funds. With these exceptions, and the further exceptions noted
 below, the following description applies generally to the Underlying Funds.
 
 A. Description of the Underlying Funds
 
 Underlying Equity Funds
 The investment advisers of the Underlying Equity Funds may, in choosing
 securities, utilize first-hand fundamental research, including visiting com-
 pany facilities to assess operations and to meet decision-makers. The
 investment advisers may also use macro analysis of numerous economic and
 valuation variables to anticipate changes in company earnings and the over-
 all investment climate. The investment advisers are able to draw on the
 research and market expertise of the Goldman Sachs Global Investment
 Research Department and other affiliates, as well as information provided by
 other securities dealers. Equity securities held by an Underlying Equity
 Fund will generally be sold when an investment adviser
 
                                                                            3-NN

 believes that the market price fully reflects or exceeds the securities'
 fundamental valuation or when other more attractive investments are identi-
 fied.
 
 Domestic Value Style Funds. The Growth and Income, Mid Cap Value and Small
 Cap Value Funds are managed using a value oriented approach. The Funds'
 investment adviser evaluates securities using fundamental analysis and
 intends to purchase equity securities that are, in its view, underpriced
 relative to a combination of such companies' long-term earnings prospects,
 growth rate, free cash flow and/or dividend-paying ability.
 
 Consideration will be given to the business quality of the issuer. Factors
 positively affecting the investment adviser's view of that quality include
 the competitiveness and degree of regulation in the markets in which the
 company operates, the existence of a management team with a record of suc-
 cess, the position of the company in the markets in which it operates, the
 level of the company's financial leverage and the sustainable return on cap-
 ital invested in the business. These Underlying Funds may also purchase
 securities of companies that have experienced difficulties and that, in the
 opinion of the investment adviser, are available at attractive prices.
 
 Domestic Growth Style Fund. The Capital Growth Fund is managed using a
 growth oriented approach. Equity securities for this Fund are selected based
 on their prospects for above average growth. The Fund's investment adviser
 will select securities of growth companies trading, in the investment advis-
 er's opinion, at a reasonable price relative to other industries, competi-
 tors and historical price/ earnings multiples. The Fund will generally
 invest in companies whose earnings are believed to be in a relatively strong
 growth trend or, to a lesser extent, in companies in which significant fur-
 ther growth is not anticipated but whose market value per share is thought
 to be undervalued.
 
 Quantitative Style Funds. The CORE U.S. Equity, CORE Large Cap Growth, CORE
 Large Cap Value, CORE Small Cap Equity and CORE International Equity Funds
 (the "CORE Equity Funds") are managed using both quantitative and fundamen-
 tal techniques. CORE is an acronym for "Computer-Optimized, Research-
 Enhanced," which reflects the Funds' investment process. This investment
 process and the proprietary multifactor model used to implement it are dis-
 cussed below.
 
 Quantitative Investment Process. The Funds' investment advisers begin with a
 broad universe of U.S. equity securities for the CORE U.S. Equity, CORE
 Large Cap Growth, CORE Large Cap Value and CORE Small Cap Equity Funds (the
 "CORE U.S. Equity Funds"), and a broad universe of foreign equity securities
 for the CORE International Equity Fund. The investment advisers use proprie-
 tary multifactor models (each a "Multifactor Model") to forecast the returns
 of differ-

                                                                      APPENDIX A
 
 ent markets, currencies and individual securities. In the case of an U.S.
 equity security followed by the Goldman Sachs Global Investment Research
 Department (the "Research Department"), a rating is assigned based upon the
 Research Department's evaluation. In the discretion of the investment advis-
 er, ratings may also be assigned to U.S. equity securities based on research
 ratings obtained from other industry sources. In the case of a foreign
 equity security, an investment adviser may rely on research from both the
 Research Department and other industry sources.
 
 In building a diversified portfolio for each CORE Equity Fund, an investment
 adviser utilizes optimization techniques to seek to maximize the Fund's
 expected return, while maintaining a risk profile similar to the Fund's
 benchmark. Each portfolio consists primarily of securities rated highest by
 the foregoing investment process and has risk characteristics and industry
 weightings similar to the relevant Fund's benchmark.
 
 Quantitative Multifactor Models. The Multifactor Models are rigorous comput-
 erized rating systems for forecasting the returns of different equity mar-
 kets, currencies, and individual equity securities according to fundamental
 investment characteristics. The CORE U.S. Equity Funds use one Multifactor
 Model to forecast the returns of securities held in each Fund's portfolio.
 The CORE International Equity Fund uses multiple Multifactor Models to fore-
 cast returns. Currently, the CORE International Equity Fund uses one model
 to forecast equity market returns, one model to forecast currency returns
 and 22 separate models to forecast individual equity security returns in 22
 different countries. Despite this variety, all Multifactor Models incorpo-
 rate common variables covering measures of value, growth, momentum and risk
 (e.g., book/price ratio, earnings/price ratio, price momentum, price vola-
 tility, consensus growth forecasts, earnings estimate revisions, earnings
 stability, and, in the case of models for the CORE International Equity
 Fund, currency momentum and country political risk ratings). All of the fac-
 tors used in the Multifactor Models have been shown to significantly impact
 the performance of the securities, currencies and markets they were designed
 to forecast.
 
 The weightings assigned to the factors in the Multifactor Model used by the
 CORE U.S. Equity Funds are derived using a statistical formulation that con-
 siders each factor's historical performance in different market environ-
 ments. As such, the U.S. Multifactor Model is designed to evaluate each
 security using only the factors that are statistically related to returns in
 the anticipated market environment. Because they include many disparate fac-
 tors, the Funds' investment advisers believe that all the Multifactor Models
 are broader in scope and provide a more thorough evaluation than most con-
 ventional, quantitative models. Securities
 
                                                                            5-NN
<PAGE>
 
 
 and markets ranked highest by the relevant Multifactor Model do not have one
 dominant investment characteristic; rather, they possess an attractive com-
 bination of investment characteristics.
 
 Research Department. In assigning ratings to equity securities, the Research
 Department uses a four category rating system ranging from "recommended for
 purchase" to "likely to underperform." The ratings reflect the analyst's
 judgment as to the investment results of a specific security and incorporate
 economic outlook, valuation, risk and a variety of other factors.
 
 By employing both a quantitative (i.e., the Multifactor Models) and a quali-
 tative (i.e., research enhanced) method of selecting securities, each CORE
 Equity Fund seeks to capitalize on the strengths of each discipline.
 
 Actively Managed International Funds. The International Equity, Japanese
 Equity, European Equity, International Small Cap, Emerging Markets Equity
 and Asia Growth Funds are managed using an active international approach.
 This approach utilizes a consistent process of stock selection undertaken by
 portfolio management teams located within each of the major investment
 regions, including Europe, Japan, Asia and the United States. In selecting
 securities, the investment adviser uses a long-term, bottom-up strategy
 based on first-hand fundamental research that is designed to give broad
 exposure to the available opportunities while seeking to add return primar-
 ily through stock selection. Equity securities for these Funds are evaluated
 based on three key factors--the business, the management and the valuation.
 The investment adviser ordinarily seeks securities that have, in its opin-
 ion, superior earnings growth potential, sustainable franchise value with
 management attuned to creating shareholder value and relatively discounted
 valuations. In addition, the investment adviser uses a multi-factor risk
 model which seeks to assure that deviations from the benchmark are justifi-
 able.
 
 Real Estate Securities Fund. The investment strategy of the Real Estate
 Securities Fund is based on the premise that property market fundamentals
 are the primary determinant of growth underlying the success of companies in
 the real estate industry. The Fund's research and investment process is
 designed to identify those companies with strong property fundamentals and
 strong management teams. This process is includes real estate market
 research and securities analysis. The Fund's investment adviser will take
 into account fundamental trends in underlying property markets as determined
 by proprietary models, research of local real estate markets, earnings, cash
 flow growth and stability, the relationship between asset values and market
 prices of the securities and dividend payment history. The investment
 adviser will attempt to purchase securities so that its underlying portfolio
 will be diversified geographically and by property type.

                                                                      APPENDIX A
 
 
 Underlying Fixed-Income Funds
 As stated above, each Underlying Fixed-Income Fund has policies relating to
 its duration (or maturity in the case of the Financial Square Prime Obliga-
 tions Fund). A Fund's duration approximates its price sensitivity to changes
 in interest rates. Maturity measures the time until final payment is due; it
 takes no account of the pattern of a security's cash flows over time. In
 computing portfolio duration, an Underlying Fixed-Income Fund will estimate
 the duration of obligations that are subject to prepayment or redemption by
 the issuer taking into account the influence of interest rates on prepay-
 ments and coupon flows. This method of computing duration is known as
 "option-adjusted" duration. A Fund will not be limited as to its maximum
 weighted average portfolio maturity or the maximum stated maturity with
 respect to individual securities unless otherwise noted.
 
 Except for the Financial Square Prime Obligations Fund (which is subject to
 more restrictive SEC regulations applicable to money market funds), an
 Underlying Fixed-Income Fund will deem a security to have met its minimum
 credit rating requirement if the security receives the minimum required
 long-term rating (or the equivalent short-term credit rating) at the time of
 purchase from at least one rating organization (including, but not limited
 to, Standard & Poor's Ratings Group ("S&P") and Moody's Investors Service,
 Inc. ("Moody's")) even though it has been rated below the minimum rating by
 one or more other rating organizations, or, if unrated by a rating organiza-
 tion, is determined by the Fund's investment adviser to be of comparable
 quality. If a security satisfies a Fund's minimum rating criteria at the
 time of purchase and is subsequently downgraded below such rating, the Fund
 will not be required to dispose of such security. If a downgrade occurs, the
 Fund's investment adviser will consider what action, including the sale of
 such security, is in the best interest of the Fund and its shareholders.
 
 The Underlying Fixed-Income Funds may (but are not required to) employ cer-
 tain active management techniques to manage their duration and term struc-
 ture, to seek to hedge exposure to foreign currencies and to seek to enhance
 returns. These techniques include (with respect to one or more of the
 Funds), but are not limited to, the use of financial futures contracts,
 option contracts (including options on futures), forward foreign currency
 exchange contracts, currency options and futures, currency, mortgage, credit
 and interest rate swaps and interest rate floors, caps and collars. Currency
 and interest rate management techniques involve risks different from those
 associated with investing solely in U.S. dollar-denominated fixed-income
 securities of U.S. issuers. Certain of the Funds may invest in custodial
 receipts, municipal securities and convertible securities. The Funds may
 also employ other investment techniques to seek to enhance returns, such as
 lending portfolio securities and entering into mortgage dollar rolls, repur-
 chase agreements, reverse repurchase agreements and other investment prac-
 tices.

 B. General Risks of the Underlying Funds
 
 The Underlying Equity Funds will be subject to the risks associated with
 common stocks and other equity securities. In general, stock values fluctu-
 ate in response to the activities of individual companies and in response to
 general market and economic conditions. Accordingly, the value of the stocks
 that a Fund holds may decline over short or extended periods. The stock mar-
 kets tend to be cyclical, with periods when stock prices generally rise and
 periods when prices generally decline.
 
 The Underlying Fixed-Income Funds will be subject to the risks associated
 with fixed-income securities. These risks include interest rate risk, credit
 risk and call/extension risk, In general, interest rate risk involves the
 risk that when interest rates decline, the market value of fixed-income
 securities tends to decline. Credit risk involves the risk that the issuer
 could default on its obligations and a Fund will not recover its investment.
 Call risk and extension risk are normally present in adjustable rate mort-
 gage loans ("ARMs"), mortgage-backed securities and asset-backed securities.
 For example, homeowners have the option to prepay their mortgages. There-
 fore, the duration of a security backed by home mortgages can either shorten
 (call risk) or lengthen (extension risk). In general, if interest rates on
 new mortgage loans fall sufficiently below the interest rates on existing
 outstanding mortgage loans, the rate of prepayment would be expected to
 increase. Conversely, if mortgage loan interest rates rise above the inter-
 est rates on existing outstanding mortgage loans, the rate of prepayment
 would be expected to decrease. In either case, a change in the prepayment
 rate can result in losses to investors.
 
 The Financial Square Prime Obligations Fund attempts to maintain a stable
 NAV of $1.00 per share and values its assets using the amortized cost method
 in accordance with SEC regulations. There is no assurance, however, that the
 Financial Square Prime Obligations Fund will be successful in maintaining
 its per share value at $1.00 on a continuous basis. The per share NAVs of
 the other Underlying Funds are expected to fluctuate on a daily basis.
 
 The turnover rates of the Underlying Funds have ranged from 41% to 315% dur-
 ing their most recent fiscal years. There can be no assurance that the turn-
 over rates of the Underlying Funds will remain within this range during sub-
 sequent fiscal years. Higher turnover rates may result in higher brokerage
 costs and expenses for the Underlying Funds. In addition, higher turn-
 over rates may result in higher taxable realized gains for shareholders.

 C. Other Risks of the Underlying Funds
 
 Risks of Investing in Small Capitalization Companies and REITs. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such securities. Small capitalization companies
 and REITs may be thinly traded and may have to be sold at a discount from
 current market prices or in small lots over an extended period of time. In
 addition, these securities are subject to the risk that during certain peri-
 ods the liquidity of particular issuers or industries, or all securities in
 these investment categories, will shrink or disappear suddenly and without
 warning as a result of adverse economic or market conditions, or adverse
 investor perceptions, whether or not accurate. Because of the lack of suffi-
 cient market liquidity, an Underlying Fund may incur losses because it will
 be required to effect sales at a disadvantageous time and only then at a
 substantial drop in price. Small capitalization companies and REITs also
 often have limited product lines, markets or financial resources; may depend
 on or use a few key personnel for management; and may be susceptible to
 losses and risks of bankruptcy. Transaction costs for these investments are
 often higher than those for larger capitalization companies. Investments in
 small capitalization companies and REITs may be more difficult to price pre-
 cisely than other types of securities because of their characteristics and
 lower trading volumes.
 
 Risks of Derivative Investments. An Underlying Fund's transactions, if any,
 in options, futures, options on futures, swaps, interest rate caps, floors
 and collars, structured securities, inverse floating-rate securities,
 stripped mortgage-backed securities and currency transactions involve addi-
 tional risk of loss. Loss can result from a lack of correlation between
 changes in the value of derivative instruments and the portfolio assets (if
 any) being hedged, the potential illiquidity of the markets for derivative
 instruments, or the risks arising from margin requirements and related lev-
 erage factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the investment adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. The Underlying Funds may also invest in derivative
 investments for non-hedging purposes (that is, to seek to increase total
 return), which is considered as a speculative practice and presents even
 greater risk of loss.
 
 Derivative mortgage-backed securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact
 
                                                                            9-NN
<PAGE>
 
 
 the cash flow and the market value of these securities. In general, the risk
 of faster than anticipated prepayments adversely affects IOs, super floaters
 and premium priced mortgage-backed securities. The risk of slower than
 anticipated prepayments generally adversely affects POs, floating-rate secu-
 rities subject to interest rate caps, support tranches and discount priced
 mortgage-backed securities. In addition, particular derivative securities
 may be leveraged such that their exposure (i.e., price sensitivity) to
 interest rate and/or prepayment risk is magnified.
 
 Floating-rate derivative debt securities can present more complex types of
 derivative and interest rate risks. For example, range floaters are subject
 to the risk that the coupon will be reduced below market rates if a desig-
 nated interest rate floats outside of a specified interest rate band or col-
 lar. Dual index or yield curve floaters are subject to lower prices in the
 event of an unfavorable change in the spread between two designated interest
 rates.
 
 Risks of Foreign Investments. Certain of the Underlying Funds may invest in
 foreign securities in accordance with their investment objectives and poli-
 cies. Foreign investments involve special risks that are not typically asso-
 ciated with U.S. dollar denominated or quoted securities of U.S. issuers.
 Foreign investments may be affected by changes in currency rates, changes in
 foreign or U.S. laws or restrictions applicable to such investments and
 changes in exchange control regulations (e.g., currency blockage). A decline
 in the exchange rate of the currency (i.e., weakening of the currency
 against the U.S. dollar) in which a portfolio security is quoted or denomi-
 nated relative to the U.S. dollar would reduce the value of the portfolio
 security.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts after January 1, 1999 that refer to existing currencies
 rather than the euro; the establishment and maintenance of exchange rates
 for currencies being converted into the euro; the fluctuation of the euro
 relative to non-euro currencies during the transition period from January 1,
 1999 to December 31, 2001 and beyond; whether the interest rate, tax and
 labor regimes of European countries participating in the euro will converge
 over time; and whether the conversion of the currencies of other countries
 in the European Union ("EU"), such as the United Kingdom and Denmark, into
 the euro and the admission of other non-EU countries such as Poland, Latvia
 and Lithuania as members of the EU may have an impact on the euro. These or
 other factors, including political and economic risks, could cause market
 disruptions, and could adversely affect the value of securities held by the
 Underlying Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States.

                                                                      APPENDIX A
 
 In addition, clearance and settlement procedures may be different in foreign
 countries and, in certain markets, such procedures have been unable to keep
 pace with the volume of securities transactions, thus making it difficult to
 conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Furthermore, with respect to certain foreign countries, there is a
 possibility of nationalization, expropriation or confiscatory taxation,
 imposition of withholding or other taxes on dividend or interest payments
 (or, in some cases, capital gains), limitations on the removal of funds or
 other assets of the Underlying Funds, and political or social instability or
 diplomatic developments which could affect investments in those countries.
 
 Concentration of a Fund's assets in one of a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations involves risks not present in debt
 obligations of corporate issuers. The issuer of the debt or the governmental
 authorities that control the repayment of the debt may be unable or unwill-
 ing to repay principal or interest when due in accordance with the terms of
 such debt, and an Underlying Fund may have limited recourse to compel pay-
 ment in the event of a default. Periods of economic uncertainty may result
 in volatility of market prices of sovereign debt, and in turn the Underlying
 Fund's NAV, to a greater extent than the volatility inherent in debt obliga-
 tions of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Underlying Funds may also invest in European
 Depository Receipts ("EDRs") or other similar instruments representing secu-
 rities of foreign issuers. ADRs represent the right to receive securities of
 foreign issuers deposited
 
                                                                           11-NN
<PAGE>
 
 
 in a domestic bank or a correspondent bank. Prices of ADRs are quoted in
 U.S. dollars, and ADRs are traded in the United States. EDRs and GDRs are
 receipts evidencing an arrangement with a non-U.S. bank. EDRs and GDRs are
 not necessarily quoted in the same currency as the underlying security.
 
 Risks of Emerging Countries. Certain Underlying Funds may invest in securi-
 ties of issuers located in emerging countries. The risks of foreign invest-
 ment are heightened when the issuer is located in an emerging country. The
 International Equity, European Equity, International Small Cap, Emerging
 Markets Equity and Asia Growth Funds may each invest without limit in the
 securities of issuers in emerging countries. Up to 35% of the total assets
 of the Emerging Markets Equity Fund may be invested in securities of issuers
 in any one emerging country. The Growth and Income, Small Cap Value, Mid Cap
 Value, High Yield and CORE International Equity Funds may each invest up to
 25%, and the Core Fixed Income, Global Income and Capital Growth Funds may
 each invest up to 10%, of their respective total assets in securities of
 issuers in emerging countries.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, such as Taiwan, it is
 anticipated that a Fund may invest in such countries only through other
 investment funds in such countries.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant invest-

                                                                      APPENDIX A
 
 ment losses. Investing in emerging countries involves greater risk of loss
 due to expropriation, nationalization, confiscation of assets and property
 or the imposition of restrictions on foreign investments and on repatriation
 of capital invested.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 An Underlying Fund's investment in emerging countries may also be subject to
 withholding or other taxes, which may be significant and may reduce the
 return from an investment in such country to the Underlying Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve an Under-
 lying Fund's delivery of securities before receipt of payment for their
 sale. In addition, significant delays are common in certain markets in reg-
 istering the transfer of securities. Settlement or registration problems may
 make it more difficult for an Underlying Fund to value its portfolio securi-
 ties and could cause the Underlying Fund to miss attractive investment
 opportunities, to have a portion of its assets uninvested or to incur losses
 due to the failure of a counterparty to pay for securities the Underlying
 Fund has delivered or the Underlying Fund's inability to complete its con-
 tractual obligations. The creditworthiness of the local securities firms
 used by the Underlying Fund in emerging countries may not be as sound as the
 creditworthiness of firms used in more developed countries, thus subjecting
 the Underlying Fund to a greater risk of loss if a securities firm defaults
 in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make an Underlying Fund's investments in such countries less liq-
 uid and more volatile than investments in countries with more developed
 securities markets (such as the United States, Japan and most Western Euro-
 pean countries). An Underlying Fund's investments in emerging countries are
 subject to the risk that the liquidity of a particular investment, or
 investments generally, in such countries will shrink or disappear suddenly
 and without warning as a result of adverse economic, market or political
 conditions, or adverse investor perceptions, whether or not accurate.
 Because of the lack of sufficient market liquidity, an Underlying Fund may
 incur losses because it will be required to effect sales at a disadvanta-
 geous time
 
                                                                           13-NN

 and only then at a substantial drop in price. Investments in emerging coun-
 tries may be more difficult to price precisely because of their characteris-
 tics and lower trading volumes.
 
 An Underlying Fund's use of foreign currency management techniques in emerg-
 ing countries may be limited. Due to the limited market for these instru-
 ments in emerging countries, the Investment Adviser does not currently
 anticipate that a significant portion of the Funds' currency exposure in
 emerging countries, if any, will be covered by such instruments.
 
 Risks of Illiquid Securities. The Underlying Funds may invest up to 15% (10%
 in the case of the Financial Square Prime Obligations Fund) of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
  ^Both domestic and foreign securities that are not readily marketable
  ^Certain municipal leases and participation interests
  ^Certain stripped mortgage-backed securities
  ^Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  ^Certain over-the-counter options
  ^Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that
   the restricted security is eligible for resale pursuant to Rule 144A
   under the Securities Act of 1933 ("144A Securities") and, therefore, is
   liquid
 
 Investing in 144A Securities may decrease the liquidity of an Underlying
 Fund's portfolio to the extent that qualified institutional buyers become
 for a time uninterested in purchasing these restricted securities. The pur-
 chase price and subsequent valuation of restricted and illiquid securities
 normally reflect a discount, which may be significant, from the market price
 of comparable securities for which a liquid market exists.
 
 Risks of Non-Diversification and Concentration. The Global Income Fund is
 registered as a "non-diversified" Fund under the 1940 Act and is, therefore,
 more susceptible to adverse developments affecting any single issuer. In
 addition, the Global Income Fund, and certain other Underlying Funds, may
 invest more than 25% of their total assets in the securities of corporate
 and governmental issuers located in a particular foreign country or region.
 Concentration of a Fund's investments in such issuers will subject the Fund,
 to a greater extent than if investment was more limited, to the risks of
 adverse securities markets, exchange rates and social, political or economic
 events which may occur in that country or region.

 Temporary Investment Risks. Each Underlying Fund (other than the CORE Funds)
 may invest up to 100% of its total assets, and each CORE Fund may invest up
 to 35% of its total assets, in short-term debt securities. When an Under-
 lying Fund's assets are invested in such instruments, the Underlying Fund
 may not be achieving its investment objective.
 
 D. Investment Securities and Techniques
 
 U.S. Government Securities. The Underlying Funds may invest in U.S. Govern-
 ment Securities. Generally, these securities include U.S. Treasury obliga-
 tions and obligations issued or guaranteed by U.S. government agencies,
 instrumentalities or sponsored enterprises. U.S. Government Securities also
 include Treasury receipts and U.S. Government Securities that have been
 stripped by the U.S. Government, where the interest and principal components
 of the securities are traded independently. Interests in U.S. Government
 Securities may be purchased in the form of custodial receipts.
 
 Mortgage-Backed Securities. The Underlying Funds (other than the five CORE
 Equity Funds) may invest in so-called "Mortgage-Backed Securities." These
 securities represent direct or indirect participations in, or are collater-
 alized by and payable from, mortgage loans secured by real property.
 Mortgage-Backed Securities can be backed by either fixed rate mortgage loans
 or adjustable rate mortgage loans, and may be issued by either a governmen-
 tal or non-governmental entity. Privately issued Mortgage-Backed Securities
 are normally structured with one or more types of "credit enhancement." How-
 ever, these Mortgage-Backed Securities typically do not have the same credit
 standing as U.S. government guaranteed Mortgage-Backed Securities.
 
 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs"), real estate mortgage invest-
 ment conduit ("REMIC") pass-through or participation certificates and
 stripped mortgage-backed securities ("SMBS"). CMOs provide an investor with
 a specified interest in the cash flow from a pool of underlying mortgages or
 of other Mortgage-Backed Securities. CMOs are issued in multiple classes. In
 most cases, payments of principal are applied to the CMO classes in the
 order of their respective stated maturities, so that no principal payments
 will be made on a CMO class until all other classes having an earlier stated
 maturity date are paid in full. A REMIC is a CMO that qualifies for special
 tax treatment and invests in certain mortgages principally secured by inter-
 ests in real property and other permitted investments. SMBS are derivative
 multiple class Mortgage-Backed Securities. The market value of SMBS consist-
 ing entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage
 
                                                                           15-NN
<PAGE>
 
 
 loans 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.
 
 Asset-Backed Securities. The Underlying Funds (other than the five CORE
 Equity Funds) may also invest in asset-backed securities. Certain Funds'
 Asset-Backed securities are limited to securities that are issued or guaran-
 teed by U.S. government agencies, instrumentalities or sponsored enter-
 prises. Asset-backed securities are securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed securities are often subject to more rapid repayment than their
 stated maturity date would indicate as a result of the pass-through of pre-
 payments of principal on the underlying loans. During periods of declining
 interest rates, prepayment of loans underlying asset-backed securities can
 be expected to accelerate. Accordingly, an Underlying Fund's ability to
 maintain positions in such securities will be affected by reductions in the
 principal amount of such securities resulting from prepayments, and its
 ability to reinvest the returns of principal at comparable yields is subject
 to generally prevailing interest rates at that time. Asset-backed securities
 present credit risks that are not presented by Mortgage-Backed Securities.
 This is because asset-backed securities generally do not have the benefit of
 a security interest in collateral that is comparable in quality to mortgage
 assets. There is the possibility that, in some cases, recoveries on
 repossessed collateral may not be available to support payments on these
 securities. In the event of a default, an Underlying Fund may suffer a loss
 if it cannot sell collateral quickly and receive the amount it is owed.
 
 Municipal Securities. Certain Underlying Funds may make limited investments
 in instruments issued by state and local governmental issuers. These securi-
 ties may include private activity bonds, municipal leases, certificates of
 participation and "auction rate" securities.
 
 Corporate Debt Obligations; Trust Preferred Securities; Convertible Securi-
 ties. The Underlying Funds may invest in corporate debt obligations, trust
 preferred securities and convertible securities. Corporate debt obligations
 include bonds, notes, debentures and other obligations of corporations to
 pay interest and repay principal, and include securities issued by banks and
 other financial institutions. A trust preferred or capital security is a
 long dated bond (for example, 30 years) with preferred features. The pre-
 ferred features are that payment of interest can be deferred for a specified
 period without initiating a default event. The securities are generally
 senior in claim to standard preferred stock but junior to other bondholders.

                                                                      APPENDIX A
 
 
 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than nonconvertible securities of similar quali-
 ty. Convertible securities in which an Underlying Fund invests are subject
 to the same rating criteria as its other investments in fixed-income securi-
 ties. Convertible securities have both equity and fixed-income risk charac-
 teristics. Like all fixed-income securities, the value of convertible secu-
 rities is susceptible to the risk of market losses attributable to changes
 in interest rates. Generally, the market value of convertible securities
 tends to decline as interest rates increase and, conversely, to increase as
 interest rates decline. However, when the market price of the common stock
 underlying a convertible security exceeds the conversion price of the con-
 vertible security, the convertible security tends to reflect the market
 price of the underlying common stock. As the market price of the underlying
 common stock declines, the convertible security, like a fixed-income securi-
 ty, tends to trade increasingly on a yield basis, and thus may not decline
 in price to the same extent as the underlying common stock.
 
 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Each Underlying Fund may invest in zero coupon, deferred interest, pay-in-
 kind and capital appreciation bonds. These securities are issued at a dis-
 count from their face value because interest payments are typically post-
 poned until maturity. Pay-in-kind securities are securities that have
 interest payable by the delivery of additional securities.The market prices
 of these securities generally are more volatile than the market prices of
 interest-bearing securities and are likely to respond to a greater degree to
 changes in interest rates than interest-bearing securities having similar
 maturities and credit quality.
 
 Rating Criteria. The rating requirements for each of the Underlying Fixed-
 Income Funds are stated above. Except as noted below, the Underlying Equity
 Funds (other than the five CORE Equity Funds, which only invest in debt
 instruments that are cash equivalents) may invest in debt securities rated
 at least investment grade at the time of investment. Investment grade debt
 securities are securities rated BBB or higher by Standard & Poor's or Baa or
 higher by Moody's. The Growth and Income, Capital Growth, Small Cap Value,
 International Equity, Japanese Equity, European Equity, International Small
 Cap, Emerging Markets Equity, Asia Growth and Real Estate Securities Funds
 may invest up to 10%, 10%, 35%, 35%, 35%, 35%, 35%, 35%, 35% and 20%,
 respectively, of their total assets in debt securities which are rated in
 the lowest rating categories by Standard & Poor's or Moody's (i.e., BB or
 lower by Standard & Poor's or Ba or lower by Moody's), including securities
 rated D by Moody's or Standard & Poor's. The Mid Cap Value Fund may invest
 up to 10% of its total assets in below investment grade debt securities
 rated B or higher by Standard & Poor's or Moody's. Fixed-
 
                                                                           17-NN
<PAGE>
 
 
 income securities rated BB or Ba or below (or comparable unrated securities)
 are commonly referred to as "junk bonds," are considered predominately spec-
 ulative and may be questionable as to principal and interest payments as
 described above.
 
 Structured Securities and Inverse Floaters. The Underlying Funds may invest
 in structured securities. Structured securities are securities whose value
 is determined by reference to changes in the value of specific currencies,
 interest rates, commodities, indices or other financial indicators (the
 "Reference") or the relative change in two or more References. The interest
 rate or the principal amount payable upon maturity or redemption may be
 increased or decreased depending upon changes in the applicable Reference.
 Structured securities may be positively or negatively indexed, so that
 appreciation of the Reference may produce an increase or decrease in the
 interest rate or value of the security at maturity. In addition, changes in
 the interest rates or the value of the security at maturity may be a multi-
 ple of changes in the value of the Reference. Consequently, structured secu-
 rities may present a greater degree of market risk than other types of
 fixed-income securities, and may be more volatile, less liquid and more dif-
 ficult to price accurately than less complex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.
 
 Foreign Currency Transactions. The Underlying Funds may, to the extent con-
 sistent with its investment policies, purchase or sell foreign currencies on
 a cash basis or through forward contracts. A forward contract involves an
 obligation to purchase or sell a specific currency at a future date at a
 price set at the time of the contract. A Fund may engage in foreign currency
 transactions for hedging purposes and to seek to protect against anticipated
 changes in future foreign currency exchange rates. In addition, certain
 Underlying Funds may also enter into such transactions to seek to increase
 total return, which is considered a speculative practice. Some Funds may
 also engage in cross-hedging by using forward contracts in a currency dif-
 ferent from that in which the hedged security is denominated or quoted if
 the investment adviser determines that there is a pattern of correlation
 between the two currencies. The Underlying Funds may hold foreign currency
 received in connection with investments in foreign securities when, in the
 judgment of its investment adviser, it would be beneficial to convert such
 currency into U.S. dollars at a later date.

 Currency exchange rates may fluctuate significantly over short periods of
 time causing, along with other factors, an Underlying Fund's value to fluc-
 tuate. Currency exchange rates also can be affected unpredictably by the
 intervention of U.S. or foreign governments or central banks, or the failure
 to intervene, or by currency controls or political developments in the
 United States or abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are not guaranteed by an exchange or clear-
 inghouse, a default on a contract would deprive an Underlying Fund of
 unrealized profits, or the benefits of a currency hedge, or could force the
 Underlying Fund to cover its purchase or sale commitments, if any, at the
 current market price.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Underlying Fund
 (other than the CORE U.S. Equity, CORE Large Cap Growth and CORE Large Cap
 Value Funds) may write (sell) covered call and put options and purchase put
 and call options on any securities in which it may invest or on any securi-
 ties index comprised of securities in which it may invest. An Underlying
 Fund, may also, to the extent it invests in foreign securities, purchase and
 sell (write) put and call options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of an investment adviser to manage future price fluctua-
 tions and the degree of correlation between the options and securities (or
 currency) markets. If an investment adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in an Underlying Fund's investment portfolio, the Underlying
 Fund may incur losses that it would not otherwise incur. The use of options
 can also increase an Underlying Fund's transaction costs. Options written or
 purchased by the Underlying Funds may be traded on either U.S. or foreign
 exchanges or over-the-counter. Foreign and over-the-counter options will
 present greater possibility of loss because of their greater liquidity and
 credit risks.

 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. The Underlying Funds may engage in
 futures transactions on both U.S. and foreign exchanges.
 
 The Underlying Funds may purchase and sell futures contracts, and purchase
 and write call and put options on futures contracts, in order to seek to
 increase total return or to hedge against changes in interest rates, securi-
 ties prices or currency exchange rates, or to otherwise manage their term
 structures and durations in accordance with their investment objectives and
 policies. The Underlying Funds may also enter into closing purchase and sale
 transactions with respect to such contracts and options. An Underlying Fund
 will engage in futures and related options transactions for bona fide hedg-
 ing purposes as defined in regulations of the Commodity Futures Trading Com-
 mission or to seek to increase total return to the extent permitted by such
 regulations. The Underlying Funds may not purchase or sell futures contracts
 or purchase or sell related options to seek to increase total return, except
 for closing purchase or sale transactions, if immediately thereafter the sum
 of the amount of initial margin deposits and premiums paid on an Underlying
 Fund's outstanding positions in futures and related options entered into for
 the purpose of seeking to increase total return would exceed 5% of the mar-
 ket value of an Underlying Fund's net assets. Futures contracts and related
 options present the following risks:
 
^While an Underlying Fund may benefit from the use of futures and options on
 futures, unanticipated changes in interest rates, securities prices or cur-
 rency exchange rates may result in a poorer overall performance than if the
 Fund had not entered into any futures contracts or options transactions.
 
^Because perfect correlation between a futures position and portfolio position
 that is intended to be protected is impossible to achieve, the desired pro-
 tection may not be obtained and an Underlying Fund may be exposed to addi-
 tional risk of loss.
 
^The loss incurred by an Underlying Fund in entering into futures contracts
 and in writing call options on futures is potentially unlimited and may
 exceed the amount of the premium received.

^Futures markets are highly volatile and the use of futures may increase the
 volatility of an Underlying Fund's NAV.
 
^As a result of the low margin deposits normally required in futures trading,
 a relatively small price movement in a futures contract may result in sub-
 stantial losses to an Underlying Fund.
 
^Futures contracts and options on futures may be illiquid, and exchanges may
 limit fluctuations in futures contract prices during a single day.
 
 ^Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 Preferred Stock, Warrants and Rights. The Underlying Funds may invest in
 preferred stock, warrants and rights. Preferred stocks are securities that
 represent an ownership interest providing the holder with claims on the
 issuer's earnings and assets before common stock owners but after bond own-
 ers. Unlike debt securities, the obligations of an issuer of preferred
 stock, including dividend and other payment obligations, may not typically
 be accelerated by the holders of such preferred stock on the occurrence of
 an event of default or other non-compliance by the issuer of the preferred
 stock. Warrants and other rights are options to buy a stated number of
 shares of common stock at a specified price at any time during the life of
 the warrant. The holders of warrants and rights have no voting rights,
 receive no dividends and have no rights with respect to the assets of the
 issuer.
 
 Real Estate Investment Trusts ("REITs"). The Real Estate Securities Fund
 expects to invest a substantial portion of its total assets in REITs, which
 are pooled investment vehicles that invest primarily in either real estate
 or real estate related loans. In addition, other Underlying Equity Funds may
 invest in REITs from time to time. The value of a REIT is affected by
 changes in the value of the properties owned by the REIT or securing mort-
 gage loans held by the REIT. REITs are dependent upon the ability of the
 REITs' managers, and are subject to heavy cash flow dependency, default by
 borrowers and the qualification of the REITs under applicable regulatory
 requirements for favorable federal income tax treatment. REITs are also sub-
 ject to risks generally associated with investments in real estate including
 possible declines in the value of real estate, general and local economic
 conditions, environmental problems and changes in interest rates. To the
 extent that assets underlying a REIT are concentrated geographically, by
 property type or in certain other respects, these risks may be heightened.
 Each Underlying Fund will indirectly bear its proportionate share of any
 expenses, including management fees, paid by a REIT in which it invests.
 
 Standard and Poor's Depository Receipts. Each Underlying Equity Fund may,
 consistent with its investment policies, purchase Standard & Poor's Deposi-
 tory
 
                                                                           21-NN
<PAGE>
 
 
 Receipts ("SPDRs"). SPDRs are American Stock Exchange-traded securities that
 represent ownership in the SPDR Trust, a trust which has been established to
 accumulate and hold a portfolio of common stocks that is intended to track
 the price performance and dividend yield of the S&P 500. The SPDR Trust is
 sponsored by a subsidiary of the American Stock Exchange. SPDRs may be used
 for several reasons, including, but not limited to, facilitating the han-
 dling of cash flows or trading or reducing transaction costs. The price
 movement of SPDRs may not perfectly parallel the price action of the S&P
 500.
 
 World Equity Benchmark Shares. World Equity Benchmark Shares ("WEBS") are
 shares of an investment company that invests substantially all of its assets
 in securities included in the MSCI indices for specified countries. WEBS are
 listed on the American Stock Exchange (the "AMEX"), and were initially
 offered to the public in 1996. The market prices of WEBS are expected to
 fluctuate in accordance with both changes in the net asset values of their
 underlying indices and supply and demand of WEBS on the AMEX. To date, WEBS
 have traded at relatively modest discounts and premiums to their net asset
 values. However, WEBS have a limited operating history, and information is
 lacking regarding the actual performance and trading liquidity of WEBS for
 extended periods or over complete market cycles. In addition, there is no
 assurance that the requirements of the AMEX necessary to maintain the list-
 ing of WEBS will continue to be met or will remain unchanged. In the event
 substantial market or other disruptions affecting WEBS should occur in the
 future, the liquidity and value of an Underlying Fund's shares could also be
 substantially and adversely affected, and the Underlying Fund's ability to
 provide investment results approximating the performance of securities in
 the EAFE Index could be impaired. If such disruptions were to occur, an
 Underlying Fund could be required to reconsider the use of WEBS as part of
 its investment strategy.
 
 Other Investment Companies. An Underlying Fund may invest in securities of
 other investment companies subject to the limitations prescribed by the
 Investment Company Act. These limitations include a prohibition on any Fund
 acquiring more than 3% of the voting shares of any other investment company,
 and a prohibition on investing more than 5% of an Underlying Fund's total
 assets in securities of any one investment company or more than 10% of its
 total assets in securities of all investment companies. An Underlying Fund
 will indirectly bear its proportionate share of any management fees and
 other expenses paid by such other investment companies. Such other invest-
 ment companies will have investment objectives, policies and restrictions
 substantially similar to those of the acquiring Fund and will be subject to
 substantially the same risks.
 
 Equity Swaps. Each Underlying Equity Fund may invest up to 10% of its total
 assets in equity swaps. Equity swaps allow the parties to a swap agreement
 to

                                                                      APPENDIX A
 
 exchange the dividend income or other components of return on an equity
 investment (e.g., a group of equity securities or an index) for a component
 of return on another non-equity or equity investment.
 
 An equity swap may be used by an Underlying Fund to invest in a market with-
 out owning or taking physical custody of securities in circumstances in
 which direct investment may be restricted for legal reasons or is otherwise
 impractical. Equity swaps are derivatives and their value can be very vola-
 tile. To the extent that an investment adviser does not accurately analyze
 and predict the potential relative fluctuation of the components swapped
 with another party, an Underlying Fund may suffer a loss. The value of some
 components of an equity swap (such as the dividends on a common stock) may
 also be sensitive to changes in interest rates. Furthermore, an Underlying
 Fund may suffer a loss if the counterparty defaults.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to an Underlying Fund at the time of entering into the
 transaction. A forward commitment involves the entering into a contract to
 purchase or sell securities for a fixed price at a future date beyond the
 customary settlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although an Underlying Fund
 will generally purchase securities on a when-issued or forward commitment
 basis with the intention of acquiring securities for its portfolio, an
 Underlying Fund may dispose of when-issued securities or forward commitments
 before settlement whenever its investment adviser deems it appropriate.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Underlying Fund may enter into repurchase
 agreements with dealers in U.S. Government Securities and member banks of
 the Federal Reserve System which furnish collateral at least equal in value
 or market price to the amount of their repurchase obligation. Some Under-
 lying Funds may also enter into repurchase agreements involving certain for-
 eign government securities. If the other party or "seller" defaults, an
 Underlying Fund might suffer a loss to the extent that the proceeds from the
 sale of the underlying securities and other collateral held by the Under-
 lying Fund in connection with the repurchase agreements are less than the
 repurchase price and the cost of the Underlying Fund associated with delay
 and enforcement of the repurchase agreement. In addition, in the event of
 
                                                                           23-NN
<PAGE>
 
 
 bankruptcy of the seller, an Underlying Fund could suffer additional losses
 if a court determines that the Underlying Fund's interest in the collateral
 is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to an
 Underlying Fund's shareholders. In addition, certain Underlying Funds,
 together with other registered investment companies having advisory agree-
 ments with the Investment Adviser or any of its affiliates, may transfer
 uninvested cash balances into a single joint account, the daily aggregate
 balance of which will be invested in one or more repurchase agreements.
 
 Lending of Portfolio Securities. Securities lending involves the lending of
 securities owned by an Underlying Fund to financial institutions such as
 certain broker-dealers. The borrowers are required to secure their loans
 continuously with cash, cash equivalents, U.S. Government Securities or let-
 ters of credit in an amount at least equal to the market value of the secu-
 rities loaned. Cash collateral may be invested in cash equivalents. If an
 investment adviser determines to make securities loans, the value of the
 securities loaned may not exceed 33 1/3% of the value of the total assets of
 an Underlying Fund (including the loan collateral).
 
 An Underlying Fund may lend its securities to increase its income. An Under-
 lying Fund may, however, experience delay in the recovery of its securities
 or possible loss if the institution with which it has engaged in a portfolio
 loan transaction breaches its agreement with the Underlying Fund.
 
 Short Sales Against-the-Box. Certain Underlying Funds may make short sales
 against-the-box. A short sale against-the-box means that at all times when a
 short position is open the Underlying Fund will own an equal amount of secu-
 rities sold short, or securities convertible into or exchangeable for, with-
 out the payment of any further consideration, an equal amount of the securi-
 ties of the same issuer as the securities sold short.
 
 Mortgage Dollar Rolls. The Underlying Fixed-Income Funds (except the High
 Yield Fund) and the Real Estate Securities Fund may enter into "mortgage
 dollar rolls." A mortgage dollar roll involves the sale by an Underlying
 Fund of securities for delivery in the current month, simultaneously con-
 tracts with the same counterparty to repurchase substantially similar (same
 type, coupon and maturity) but not identical securities on a specified
 future date. During the roll period, the Underlying Fund loses the right to
 receive principal and interest paid on the securities sold. However, the
 Underlying Fund benefits to the extent of any difference between (a) the
 price received for the securities sold and (b) the lower forward price for
 the future purchase and/or fee income plus the interest earned on the

 cash proceeds of the securities sold. Unless the benefits of a mortgage dol-
 lar roll exceed the income, capital appreciation and gain or loss due to
 mortgage prepayments that would have been realized on the securities sold as
 part of the roll, the use of this technique will diminish the performance of
 the Underlying Fund.
 
 Successful use of mortgage dollar rolls depends upon the Investment Advis-
 er's ability to predict correctly interest rates and mortgage prepayments.
 If the Investment Adviser is incorrect in its prediction, a Fund may experi-
 ence a loss. For financial reporting and tax purposes, the Funds treat mort-
 gage dollar rolls as two separate transactions: one involving the purchase
 of a security and a separate transaction involving a sale. The Funds do not
 currently intend to enter into mortgage dollar rolls that are accounted for
 as a financing and do not treat them as borrowings.
 
 Borrowings and Reverse Repurchase Agreements. The Underlying Funds can bor-
 row money from banks and enter into reverse repurchase agreements with banks
 and other financial institutions in amounts not exceeding one-third of its
 total assets. Reverse repurchase agreements involve the sale of securities
 held by an Underlying Fund subject to the Underlying Fund's agreement to
 repurchase them at a mutually agreed upon date and price (including inter-
 est). These transactions may be entered into as a temporary measure for
 emergency purposes or to meet redemption requests. Reverse repurchase agree-
 ments may also be entered into when the investment adviser expects that the
 interest income to be earned from the investment of the transaction proceeds
 will be greater than the related interest expense. Borrowings and reverse
 repurchase agreements involve leveraging. If the securities held by an
 Underlying Fund decline in value while these transactions are outstanding,
 the NAV of the Underlying Fund's outstanding shares will decline in value by
 proportionately more than the decline in value of the securities. In addi-
 tion, reverse repurchase agreements involve the risk that any interest
 income earned by an Underlying Fund (from the investment of the proceeds)
 will be less than the interest expense of the transaction, that the market
 value of the securities sold by an Underlying Fund will decline below the
 price the Underlying Fund is obligated to pay to repurchase the securities,
 and that the securities may not be returned to the Underlying Fund.
 
 Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Inter-
 est Rate Caps, Floors and Collars. To the extent consistent with their
 investment policies, the Underlying Funds may enter into interest rate
 swaps, mortgage swaps, credit swaps, currency swaps and interest rate caps,
 floors and collars. Interest rate swaps involve the exchange by an Under-
 lying Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest
 
                                                                           25-NN
<PAGE>
 
 
 rate swaps in that they represent commitments to pay and receive interest.
 The notional principal amount, however, is tied to a reference pool or pools
 of mortgages. Credit swaps involve the receipt of floating or fixed rate
 payments in exchange for assuming potential credit losses of an underlying
 security. Credit swaps give one party to a transaction the right to dispose
 of or acquire an asset (or group of assets), or the right to receive or make
 a payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest rate, to receive payment of interest
 on a notional principal amount from the party selling such interest rate
 cap. The purchase of an interest rate floor entitles the purchaser, to the
 extent that a specified index falls below a predetermined interest rate, to
 receive payments of interest on a notional principal amount from the party
 selling the interest rate floor. An interest rate collar is the combination
 of a cap and a floor that preserves a certain return within a predetermined
 range of interest rates.
 
 An Underlying Fund may enter into swap transactions for hedging purposes or
 to seek to increase total return. The use of interest rate, mortgage, credit
 and currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If the investment adviser is incorrect in its forecasts of market
 value, interest rates and currency exchange rates, the investment perfor-
 mance of an Underlying Fund would be less favorable than it would have been
 if these investment techniques were not used.
 
 Miscellaneous Techniques
 
 In addition to the techniques and investments described above, certain
 Underlying Funds may engage in the following techniques and investments: (i)
 yield curve options (Underlying Fixed-Income Funds and Real Estate Securi-
 ties Fund only); (ii) loan participations (High Yield Fund only); and (iii)
 unseasoned companies.

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

General Investment
Management Approach
 
Goldman Sachs Asset Management, a separate operating division of Goldman, Sachs
& Co. ("Goldman Sachs"), serves as investment adviser (the "Investment Advis-
er") to five asset allocation portfolios: the Conservative Strategy Portfolio,
Balanced Strategy Portfolio (formerly, the Income Strategy Portfolio), Growth
and Income Strategy Portfolio, Growth Strategy Portfolio and Aggressive Growth
Strategy Portfolio (referred to as the "Portfolios" or the "Funds" interchange-
ably herein). The Portfolios are intended for investors who prefer to have
their asset allocation decisions made by professional money managers. Each
Portfolio seeks to achieve its objectives by investing in a combination of
underlying funds for which Goldman Sachs now or in the future acts as invest-
ment adviser or principal underwriter (the "Underlying Funds"). Some of these
Funds invest primarily in fixed-income or money market securities (the "Under-
lying Fixed-Income Funds"); other Funds invest primarily in equity securities
(the "Underlying Equity Funds"). You may choose to invest in one or more of the
Portfolios based on your personal investment goals, risk tolerance, and finan-
cial circumstances.
 
Goldman Sachs' Asset Allocation Investment Philosophy
The Investment Adviser's Quantitative Research Group uses disciplined quantita-
tive models to determine the relative attractiveness of the world's stock, bond
and currency markets. These models use financial and economic variables to cap-
ture fundamental relationships that it believes make sense. While the Invest-
ment Adviser's process is rigorous and quantitative, it also incorporates clear
economic reasoning behind each recommendation.
 
Each Portfolio starts with a "base-line" or strategic allocation among the var-
ious asset classes. The Investment Adviser then tactically deviates from the
strategic allocations based on forecasts provided by the models. The tactical
process seeks to add value by overweighing attractive markets and underweighing
unattractive markets. Greater deviations from the strategic allocation of a
given Portfolio result in higher risk that the tactical allocation will
underperform the strategic allocation. However, the Investment Adviser's risk
control process balances the amount any asset class can be overweighed in seek-
ing to achieve higher expected returns
 
 The Asset Allocation Investment Philosophy involves investing a Portfolio's
 assets in other Goldman Sachs Funds within specified equity and fixed-income
 percentage ranges.

 against the amount of risk imposed by that deviation from the strategic
 allocation. The Investment Adviser employs Goldman Sachs' proprietary Black-
 Litterman asset allocation technique in an effort to optimally balance these
 two goals. This technique combines the Quantitative Research Group's market
 forecast with economic equilibrium in seeking to construct risk-controlled
 portfolios.

Portfolio Investment Objectives and Strategies
 
 Goldman Sachs Conservative Strategy Portfolio
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income, consistent with the preservation of cap-
 ital and secondarily also considers the potential for capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 80% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds, with a focus on
 short-term investments including money market funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its assets in
 the Global Income Fund, Financial Square Prime Obligations Fund and CORE
 Large Cap Value Fund. It is expected that the Portfolio will invest more
 than 25% of its assets in the Short Duration Government Fund. The Portfolio
 may not invest in International Underlying Equity Funds.

<PAGE>
 
Goldman Sachs Balanced Strategy Portfolio
 
 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks current income and long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 60% of the Portfolio's total assets
 will be allocated among Underlying Fixed-Income Funds. Allocation to Under-
 lying Equity Funds is intended to add diversification and enhance returns,
 but will also add some volatility. The Investment Adviser expects that the
 Portfolio will invest a relatively significant percentage of its equity
 allocation in the CORE Large Cap Growth, CORE Large Cap Value and CORE
 International Equity Funds and will invest a relatively significant percent-
 age of its assets in the Global Income Fund. It is expected that the Portfo-
 lio will invest more than 25% of its assets in the Short Duration Government
 Fund.

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

 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, approximately 80% of the Portfolio's total assets
 will be allocated among Underlying Equity Funds, with a blend of domestic
 large cap, small cap and international exposure to seek capital apprecia-
 tion. Allocation to Underlying Fixed-Income Funds is intended to provide
 diversification. The Investment Adviser expects that the Portfolio will
 invest a relatively significant percentage of its equity allocation in the
 CORE Large Cap Growth, CORE Large Cap Value and CORE International Equity
 Funds.

 INVESTMENT OBJECTIVE
 
 
 The Portfolio seeks long-term capital appreciation.
 
 PRINCIPAL INVESTMENT STRATEGY
 
 
 Under normal conditions, substantially all of the Portfolio's total assets
 will be allocated among Underlying Equity Funds, with a greater focus on
 small cap and international investments. The Investment Adviser expects that
 the Portfolio will invest a relatively significant percentage of its assets
 in the CORE Large Cap Growth, CORE Large Cap Value and CORE International
 Equity Funds.

Principal Investment Strategies
 
Each Portfolio seeks to achieve its investment objective by investing within
specified equity and fixed-income ranges among Underlying Funds. The table

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

                                                 PRINCIPAL INVESTMENT STRATEGIES
 
 
 While each Portfolio can invest in any or all of the Underlying Funds, it is
 expected that each Portfolio will normally invest in only some of the Under-
 lying Funds at any particular time. Each Portfolio's investment in any of
 the Underlying Funds may, and in some cases is expected to, exceed 25% of
 such Portfolio's total assets.
 
 THE PARTICULAR UNDERLYING FUNDS IN WHICH EACH PORTFOLIO MAY INVEST, THE
 EQUITY/FIXED INCOME TARGETS AND RANGES AND THE INVESTMENTS IN EACH UNDER-
 LYING FUND MAY BE CHANGED FROM TIME TO TIME WITHOUT SHAREHOLDER APPROVAL.

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

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

Principal Risks of the Underlying Funds
 
The following summarizes important risks that apply to the Underlying Funds and
may result in a loss of your investment in a Portfolio. There can be no assur-
ance that an Underlying Fund will achieve its investment objective.
 
Risks That Apply To All Underlying Funds:
 
 ^Market Risk--The risk that the value of the securities in which an Under-
  lying Fund invests may go up or down in response to the prospects of indi-
  vidual companies and/or general economic conditions. Price changes may be
  temporary or last for extended periods.
 ^Derivatives Risk--The risk that loss may result from an Underlying Fund's
  investments in options, futures, swaps, structured securities and other
  derivative instruments, which may be leveraged.
 ^Management Risk--The risk that a strategy used by an investment adviser to
  the Underlying Funds may fail to produce the intended results.
 ^Liquidity Risk--The risk that an Underlying Fund will not be able to pay
  redemption proceeds within the time period stated in this Prospectus,
  because of unusual market conditions, an unusually high volume of redemp-
  tion requests, or other reasons. Funds that invest in small capitalization
  stocks, REITs and emerging country issuers will be especially subject to
  the risk that during certain periods the liquidity of particular issuers or
  industries, or all securities within these investment categories, will
  shrink or disappear suddenly and without warning as a result of adverse
  economic, market or political events, or adverse investor perceptions,
  whether or not accurate.
 ^Other Risks--Each Underlying Fund is subject to other risks, such as the
  risk that its operations, or the value of its portfolio securities, will be
  disrupted by the "Year 2000 Problem."
 
Risks That Apply Primarily To The Underlying Fixed-Income Funds:
 
 ^Interest Rate Risk--The risk that when interest rates increase, fixed-
  income securities held by an Underlying Fund will decline in value. Long-
  term fixed-income securities will normally have more price volatility
  because of this risk than short-term securities.
 ^Credit/Default Risk--The risk that an issuer of fixed-income securities
  held by an Underlying Fund (which may have low credit ratings) may default
  on its obligation to pay interest and repay principal.
 ^Call Risk--The risk that an issuer will exercise its right to pay principal
  on an obligation held by an Underlying Fund (such as a mortgage-backed secu-
 
                                                                            17-Z

  rity) earlier than expected. This may happen when there is a decline in
  interest rates. Under these circumstances, an Underlying Fund may be unable
  to recoup all of its initial investment and will also suffer from having to
  reinvest in lower yielding securities.
 ^Extension Risk--The risk that an issuer will exercise its right to pay
  principal on an obligation held by an Underlying Fund (such as a mortgage-
  backed security) later than expected. This may happen when there is a rise
  in interest rates. Under these circumstances, the value of an obligation
  will decrease, and an Underlying Fund will also suffer from the inability
  to invest in higher yielding securities.
 ^Government Securities Risk--The risk that the U.S. government will not pro-
  vide financial support to U.S. government agencies, instrumentalities or
  sponsored enterprises if it is not obligated to do so by law.
 
Risk That Applies Primarily To The Underlying Equity Funds:
 
 ^Stock Risk--The risk that stock prices have historically risen and fallen
  in periodic cycles. As of the date of this Prospectus, U.S. stock markets
  and certain foreign stock markets were trading at or close to record high
  levels. There is no guarantee that such levels will continue.
 
Risks That Are Particularly Important For Specific Underlying Funds:
 
 ^Concentration Risk--The European Equity Fund invests primarily in equity
  securities of European companies. The Japanese Equity Fund invests primar-
  ily in equity securities of Japanese companies. The Global Income Fund may
  invest more than 25% of its total assets in the securities of corporate and
  governmental issuers located in each of Canada, Germany, Japan, and the
  United Kingdom as well as in the securities of U.S. issuers. Concentration
  of the investments of these or other Underlying Funds in issuers located in
  a particular country or region will subject the Underlying Fund, to a
  greater extent than if investments were not so concentrated, to the risks
  of adverse securities markets, exchange rates and social, political, regu-
  latory or economic events which may occur in that country or region.
 ^Foreign Risks--Underlying Funds that invest in foreign securities will be
  subject to risks with respect to their foreign investments that are not
  typically associated with domestic issuers. These risks result from less
  government regulation, less public information and less economic, political
  and social stability. These risks may involve the imposition of exchange
  controls, confiscation and other government restrictions. The Underlying
  Funds will also be subject to the risk of negative foreign currency rate
  fluctuations. Foreign risks will normally be greatest when an Underlying
  Fund invests in issuers located in emerging countries.

                                         PRINCIPAL RISKS OF THE UNDERLYING FUNDS
 
 ^Emerging Markets Risk--The securities markets of Asian, Latin American,
  Eastern European, African and other emerging countries are less liquid, are
  especially subject to greater price volatility, have smaller market capi-
  talizations, have less government regulation and are not subject to as
  extensive and frequent accounting, financial and other reporting require-
  ments as the securities markets of more developed countries. Further,
  investment in equity securities of issuers located in Russia and certain
  other emerging countries involves risk of loss resulting from problems in
  share registration and custody and substantial economic and political dis-
  ruptions. These risks are not normally associated with investments in more
  developed countries.
 ^"Junk Bond" Risk--The High Yield Fund will invest in non-investment grade
  fixed-income securities (commonly known as "junk bonds") that are consid-
  ered predominantly speculative by traditional investment standards. Non-
  investment grade fixed-income securities and unrated securities of compara-
  ble credit quality are subject to the increased risk of an issuer's
  inability to meet principal and interest payment obligations. These securi-
  ties may be subject to greater price volatility due to such factors as spe-
  cific corporate developments, interest rate sensitivity, negative percep-
  tions of the junk bond markets generally and less secondary market
  liquidity.
 ^Small Cap Stock and REIT Risks--The securities of small capitalization com-
  panies and REITs involve greater risks than those associated with larger,
  more established companies, and the securities may be subject to more
  abrupt or erratic price movements. Securities of such issuers may lack suf-
  ficient market liquidity to enable an Underlying Fund to effect sales at an
  advantageous time or without a substantial drop in price.
 
More information about the portfolio securities and investment techniques of
the Underlying Funds, and their associated risks, is provided in Appendix A.
You should consider the investment risks discussed in this section and in
Appendix A. Both are important to your investment choice.

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

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

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

Service Organizations may charge other fees directly to their customers who are
the beneficial owners of Service Shares in connection with their customers'
accounts. You should contact your service organization for information regard-
ing such charges. Such fees may affect the return their customers realize with
respect to their investments.
 
Certain Service Organizations may receive other compensation in connection with
the sale and distribution of Service Shares or for services to their customers'
accounts and/or the Portfolios. For additional information regarding such com-
pensation, see "Shareholder Guide" in the Prospectus and "Other Information" in
the Statement of Additional Information ("Additional Statement").

                                                                            1-AA

 investment transactions, including determinations concerning changes to (a)
 the Underlying Funds in which the Portfolios may invest and (b) the percent-
 age range of assets of any Portfolio that may be invested in the Underlying

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

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

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

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

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

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

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

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

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

 employed, the Trust may be liable for any loss due to unauthorized or fraud-
 ulent transactions. The following general policies are currently in effect:
..All telephone requests are recorded.
..Any redemption request that requires money to go to an account or address
  other than that designated on the Account Application must be in writing
  and signed by an authorized person designated on the Account Application.
  The written request will be confirmed by telephone with both the requesting
  party and the designated bank account to verify instructions.
..The telephone redemption option may be modified or terminated at any time.
 
 Note: It may be difficult to make telephone redemptions in times of drastic
 economic or market conditions.
 
 How Are Redemption Proceeds Paid?
 By Wire: The Funds will arrange for redemption proceeds to be wired as fed-
 eral funds to the bank account designated in the recordholder's Account
 Application. The following general policies govern wiring redemption pro-
 ceeds:
..Redemption proceeds will normally be wired on the next business day in fed-
  eral funds (for a total of one business day delay), but may be paid up to
  three business days following receipt of a properly executed wire transfer
  redemption request, unless you are selling shares you recently paid for by
  check. In that case, the Funds will pay you when your check has cleared,
  which may take up to 15 days. If the Federal Reserve Bank is closed on the
  day that the redemption proceeds would ordinarily be wired, wiring the
  redemption proceeds may be delayed one additional business day.
..Neither the Trust nor Goldman Sachs assumes any responsibility for the per-
  formance of intermediaries or your Service Organization in the transfer
  process. If a problem with such performance arises, you should deal
  directly with such intermediaries or Service Organization.
..If the redeemed shares were recently paid for by check, the Funds will pay
  the redemption proceeds when the check has cleared, which may take up to 15
  days.
 
 By Check: A recordholder may elect in writing to receive redemption proceeds
 by check. Redemption proceeds paid by check will normally be mailed to the
 address of record within three business days of receipt of a properly exe-
 cuted redemption request, unless the shares to be sold were recently paid
 for by check. In that case, the Funds will pay the redemption proceeds when
 the check has cleared, which may take up to 15 days.
 
                                                                             5-H
<PAGE>
 
 
 What Else Do I Need To Know About Redemptions?
 The following generally applies to redemption requests:
..Additional documentation may be required when deemed appropriate by the
  Transfer Agent. A redemption request will not be in proper form until such
  additional documentation has been received.
..Service Organizations are responsible for the timely transmittal of redemp-
  tion requests by their customers to the Transfer Agent. In order to facili-
  tate the timely transmittal of redemption requests, Service Organizations
  may set times by which they must receive redemption requests. Service Orga-
  nizations may also require additional documentation from you.
 
 The Trust reserves the right to:
..Redeem the Service Shares of any Service Organization whose account balance
  falls below $50 as a result of earlier redemptions. The Funds will not
  redeem Service Shares on this basis if the value of the account falls below
  the minimum account balance solely as a result of market conditions. The
  Fund will give 60 days' prior written notice to allow a Service Organiza-
  tion to purchase sufficient additional shares of the Fund in order to avoid
  such redemption.
..Redeem the shares in other circumstances determined by the Board of Trust-
  ees to be in the interests of the Trust.
..Pay redemptions by a distribution in-kind of securities (instead of cash).
  If you receive redemption proceeds in-kind, you should expect to incur
  transaction costs upon the disposition of those securities.
 
 Can I Exchange My Investment From One Fund To Another?
 A Service Organization may exchange Service Shares of a Fund at NAV for
 Service Shares of any other Goldman Sachs Fund. The exchange privilege may
 be materially modified or withdrawn at any time upon 60 days' written notice
 to you.

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

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

Appendix A
 
Additional Information on the Underlying Funds
 This Appendix provides further information on certain types of securities
 and techniques that may be used by the Underlying Funds, including their
 associated risks. Additional information is provided in the Additional
 Statement, which is available upon request, and in the prospectuses of the
 Underlying Funds.
 
 The Underlying Equity Funds invest primarily in common stocks and other
 equity securities, including preferred stocks, interests in real estate
 investment trusts, convertible debt obligations, convertible preferred
 stocks, equity interests in trusts, partnerships, joint ventures, limited
 liability companies and similar enterprises, warrants and stock purchase
 rights ("equity securities"). The Underlying Fixed-Income Funds invest pri-
 marily in fixed-income securities, including senior and subordinated corpo-
 rate debt obligations (such as bonds, debentures, notes and commercial
 paper), convertible and non-convertible corporate debt obligations, loan
 participations and preferred stock.
 
 The Short Duration Government and Adjustable Rate Government Funds invest in
 U.S. Government Securities and related repurchase agreements, and neither of
 these Funds, the Government Income Fund nor the Financial Square Prime Obli-
 gations Fund makes foreign investments. The investments of the Financial
 Square Prime Obligations Fund are limited by SEC regulations applicable to
 money market funds as described in its prospectus, and do not include many
 of the types of investments discussed below that are permitted for the other
 Underlying Funds. With these exceptions, and the further exceptions noted
 below, the following description applies generally to the Underlying Funds.
 
 A. Description of the Underlying Funds
 
 Underlying Equity Funds
 The investment advisers of the Underlying Equity Funds may, in choosing
 securities, utilize first-hand fundamental research, including visiting com-
 pany facilities to assess operations and to meet decision-makers. The
 investment advisers may also use macro analysis of numerous economic and
 valuation variables to anticipate changes in company earnings and the over-
 all investment climate. The investment advisers are able to draw on the
 research and market expertise of the Goldman Sachs Global Investment
 Research Department and other affiliates, as well as information provided by
 other securities dealers. Equity securities held by an Underlying Equity
 Fund will generally be sold when an investment adviser
 
                                                                            3-NN

 believes that the market price fully reflects or exceeds the securities'
 fundamental valuation or when other more attractive investments are identi-
 fied.
 
 Domestic Value Style Funds. The Growth and Income, Mid Cap Value and Small
 Cap Value Funds are managed using a value oriented approach. The Funds'
 investment adviser evaluates securities using fundamental analysis and
 intends to purchase equity securities that are, in its view, underpriced
 relative to a combination of such companies' long-term earnings prospects,
 growth rate, free cash flow and/or dividend-paying ability.
 
 Consideration will be given to the business quality of the issuer. Factors
 positively affecting the investment adviser's view of that quality include
 the competitiveness and degree of regulation in the markets in which the
 company operates, the existence of a management team with a record of suc-
 cess, the position of the company in the markets in which it operates, the
 level of the company's financial leverage and the sustainable return on cap-
 ital invested in the business. These Underlying Funds may also purchase
 securities of companies that have experienced difficulties and that, in the
 opinion of the investment adviser, are available at attractive prices.
 
 Domestic Growth Style Fund. The Capital Growth Fund is managed using a
 growth oriented approach. Equity securities for this Fund are selected based
 on their prospects for above average growth. The Fund's investment adviser
 will select securities of growth companies trading, in the investment advis-
 er's opinion, at a reasonable price relative to other industries, competi-
 tors and historical price/ earnings multiples. The Fund will generally
 invest in companies whose earnings are believed to be in a relatively strong
 growth trend or, to a lesser extent, in companies in which significant fur-
 ther growth is not anticipated but whose market value per share is thought
 to be undervalued.
 
 Quantitative Style Funds. The CORE U.S. Equity, CORE Large Cap Growth, CORE
 Large Cap Value, CORE Small Cap Equity and CORE International Equity Funds
 (the "CORE Equity Funds") are managed using both quantitative and fundamen-
 tal techniques. CORE is an acronym for "Computer-Optimized, Research-
 Enhanced," which reflects the Funds' investment process. This investment
 process and the proprietary multifactor model used to implement it are dis-
 cussed below.
 
 Quantitative Investment Process. The Funds' investment advisers begin with a
 broad universe of U.S. equity securities for the CORE U.S. Equity, CORE
 Large Cap Growth, CORE Large Cap Value and CORE Small Cap Equity Funds (the
 "CORE U.S. Equity Funds"), and a broad universe of foreign equity securities
 for the CORE International Equity Fund. The investment advisers use proprie-
 tary multifactor models (each a "Multifactor Model") to forecast the returns
 of differ-

                                                                      APPENDIX A
 
 ent markets, currencies and individual securities. In the case of an U.S.
 equity security followed by the Goldman Sachs Global Investment Research
 Department (the "Research Department"), a rating is assigned based upon the
 Research Department's evaluation. In the discretion of the investment advis-
 er, ratings may also be assigned to U.S. equity securities based on research
 ratings obtained from other industry sources. In the case of a foreign
 equity security, an investment adviser may rely on research from both the
 Research Department and other industry sources.
 
 In building a diversified portfolio for each CORE Equity Fund, an investment
 adviser utilizes optimization techniques to seek to maximize the Fund's
 expected return, while maintaining a risk profile similar to the Fund's
 benchmark. Each portfolio consists primarily of securities rated highest by
 the foregoing investment process and has risk characteristics and industry
 weightings similar to the relevant Fund's benchmark.
 
 Quantitative Multifactor Models. The Multifactor Models are rigorous comput-
 erized rating systems for forecasting the returns of different equity mar-
 kets, currencies, and individual equity securities according to fundamental
 investment characteristics. The CORE U.S. Equity Funds use one Multifactor
 Model to forecast the returns of securities held in each Fund's portfolio.
 The CORE International Equity Fund uses multiple Multifactor Models to fore-
 cast returns. Currently, the CORE International Equity Fund uses one model
 to forecast equity market returns, one model to forecast currency returns
 and 22 separate models to forecast individual equity security returns in 22
 different countries. Despite this variety, all Multifactor Models incorpo-
 rate common variables covering measures of value, growth, momentum and risk
 (e.g., book/price ratio, earnings/price ratio, price momentum, price vola-
 tility, consensus growth forecasts, earnings estimate revisions, earnings
 stability, and, in the case of models for the CORE International Equity
 Fund, currency momentum and country political risk ratings). All of the fac-
 tors used in the Multifactor Models have been shown to significantly impact
 the performance of the securities, currencies and markets they were designed
 to forecast.
 
 The weightings assigned to the factors in the Multifactor Model used by the
 CORE U.S. Equity Funds are derived using a statistical formulation that con-
 siders each factor's historical performance in different market environ-
 ments. As such, the U.S. Multifactor Model is designed to evaluate each
 security using only the factors that are statistically related to returns in
 the anticipated market environment. Because they include many disparate fac-
 tors, the Funds' investment advisers believe that all the Multifactor Models
 are broader in scope and provide a more thorough evaluation than most con-
 ventional, quantitative models. Securities
 
                                                                            5-NN
<PAGE>
 
 
 and markets ranked highest by the relevant Multifactor Model do not have one
 dominant investment characteristic; rather, they possess an attractive com-
 bination of investment characteristics.
 
 Research Department. In assigning ratings to equity securities, the Research
 Department uses a four category rating system ranging from "recommended for
 purchase" to "likely to underperform." The ratings reflect the analyst's
 judgment as to the investment results of a specific security and incorporate
 economic outlook, valuation, risk and a variety of other factors.
 
 By employing both a quantitative (i.e., the Multifactor Models) and a quali-
 tative (i.e., research enhanced) method of selecting securities, each CORE
 Equity Fund seeks to capitalize on the strengths of each discipline.
 
 Actively Managed International Funds. The International Equity, Japanese
 Equity, European Equity, International Small Cap, Emerging Markets Equity
 and Asia Growth Funds are managed using an active international approach.
 This approach utilizes a consistent process of stock selection undertaken by
 portfolio management teams located within each of the major investment
 regions, including Europe, Japan, Asia and the United States. In selecting
 securities, the investment adviser uses a long-term, bottom-up strategy
 based on first-hand fundamental research that is designed to give broad
 exposure to the available opportunities while seeking to add return primar-
 ily through stock selection. Equity securities for these Funds are evaluated
 based on three key factors--the business, the management and the valuation.
 The investment adviser ordinarily seeks securities that have, in its opin-
 ion, superior earnings growth potential, sustainable franchise value with
 management attuned to creating shareholder value and relatively discounted
 valuations. In addition, the investment adviser uses a multi-factor risk
 model which seeks to assure that deviations from the benchmark are justifi-
 able.
 
 Real Estate Securities Fund. The investment strategy of the Real Estate
 Securities Fund is based on the premise that property market fundamentals
 are the primary determinant of growth underlying the success of companies in
 the real estate industry. The Fund's research and investment process is
 designed to identify those companies with strong property fundamentals and
 strong management teams. This process is includes real estate market
 research and securities analysis. The Fund's investment adviser will take
 into account fundamental trends in underlying property markets as determined
 by proprietary models, research of local real estate markets, earnings, cash
 flow growth and stability, the relationship between asset values and market
 prices of the securities and dividend payment history. The investment
 adviser will attempt to purchase securities so that its underlying portfolio
 will be diversified geographically and by property type.

                                                                      APPENDIX A
 
 
 Underlying Fixed-Income Funds
 As stated above, each Underlying Fixed-Income Fund has policies relating to
 its duration (or maturity in the case of the Financial Square Prime Obliga-
 tions Fund). A Fund's duration approximates its price sensitivity to changes
 in interest rates. Maturity measures the time until final payment is due; it
 takes no account of the pattern of a security's cash flows over time. In
 computing portfolio duration, an Underlying Fixed-Income Fund will estimate
 the duration of obligations that are subject to prepayment or redemption by
 the issuer taking into account the influence of interest rates on prepay-
 ments and coupon flows. This method of computing duration is known as
 "option-adjusted" duration. A Fund will not be limited as to its maximum
 weighted average portfolio maturity or the maximum stated maturity with
 respect to individual securities unless otherwise noted.
 
 Except for the Financial Square Prime Obligations Fund (which is subject to
 more restrictive SEC regulations applicable to money market funds), an
 Underlying Fixed-Income Fund will deem a security to have met its minimum
 credit rating requirement if the security receives the minimum required
 long-term rating (or the equivalent short-term credit rating) at the time of
 purchase from at least one rating organization (including, but not limited
 to, Standard & Poor's Ratings Group ("S&P") and Moody's Investors Service,
 Inc. ("Moody's")) even though it has been rated below the minimum rating by
 one or more other rating organizations, or, if unrated by a rating organiza-
 tion, is determined by the Fund's investment adviser to be of comparable
 quality. If a security satisfies a Fund's minimum rating criteria at the
 time of purchase and is subsequently downgraded below such rating, the Fund
 will not be required to dispose of such security. If a downgrade occurs, the
 Fund's investment adviser will consider what action, including the sale of
 such security, is in the best interest of the Fund and its shareholders.
 
 The Underlying Fixed-Income Funds may (but are not required to) employ cer-
 tain active management techniques to manage their duration and term struc-
 ture, to seek to hedge exposure to foreign currencies and to seek to enhance
 returns. These techniques include (with respect to one or more of the
 Funds), but are not limited to, the use of financial futures contracts,
 option contracts (including options on futures), forward foreign currency
 exchange contracts, currency options and futures, currency, mortgage, credit
 and interest rate swaps and interest rate floors, caps and collars. Currency
 and interest rate management techniques involve risks different from those
 associated with investing solely in U.S. dollar-denominated fixed-income
 securities of U.S. issuers. Certain of the Funds may invest in custodial
 receipts, municipal securities and convertible securities. The Funds may
 also employ other investment techniques to seek to enhance returns, such as
 lending portfolio securities and entering into mortgage dollar rolls, repur-
 chase agreements, reverse repurchase agreements and other investment prac-
 tices.

 B. General Risks of the Underlying Funds
 
 The Underlying Equity Funds will be subject to the risks associated with
 common stocks and other equity securities. In general, stock values fluctu-
 ate in response to the activities of individual companies and in response to
 general market and economic conditions. Accordingly, the value of the stocks
 that a Fund holds may decline over short or extended periods. The stock mar-
 kets tend to be cyclical, with periods when stock prices generally rise and
 periods when prices generally decline.
 
 The Underlying Fixed-Income Funds will be subject to the risks associated
 with fixed-income securities. These risks include interest rate risk, credit
 risk and call/extension risk, In general, interest rate risk involves the
 risk that when interest rates decline, the market value of fixed-income
 securities tends to decline. Credit risk involves the risk that the issuer
 could default on its obligations and a Fund will not recover its investment.
 Call risk and extension risk are normally present in adjustable rate mort-
 gage loans ("ARMs"), mortgage-backed securities and asset-backed securities.
 For example, homeowners have the option to prepay their mortgages. There-
 fore, the duration of a security backed by home mortgages can either shorten
 (call risk) or lengthen (extension risk). In general, if interest rates on
 new mortgage loans fall sufficiently below the interest rates on existing
 outstanding mortgage loans, the rate of prepayment would be expected to
 increase. Conversely, if mortgage loan interest rates rise above the inter-
 est rates on existing outstanding mortgage loans, the rate of prepayment
 would be expected to decrease. In either case, a change in the prepayment
 rate can result in losses to investors.
 
 The Financial Square Prime Obligations Fund attempts to maintain a stable
 NAV of $1.00 per share and values its assets using the amortized cost method
 in accordance with SEC regulations. There is no assurance, however, that the
 Financial Square Prime Obligations Fund will be successful in maintaining
 its per share value at $1.00 on a continuous basis. The per share NAVs of
 the other Underlying Funds are expected to fluctuate on a daily basis.
 
 The turnover rates of the Underlying Funds have ranged from 41% to 315% dur-
 ing their most recent fiscal years. There can be no assurance that the turn-
 over rates of the Underlying Funds will remain within this range during sub-
 sequent fiscal years. Higher turnover rates may result in higher brokerage
 costs and expenses for the Underlying Funds. In addition, higher turn-
 over rates may result in higher taxable realized gains for shareholders.

 C. Other Risks of the Underlying Funds
 
 Risks of Investing in Small Capitalization Companies and REITs. Investments
 in small capitalization companies and REITs involve greater risk and portfo-
 lio price volatility than investments in larger capitalization stocks. Among
 the reasons for the greater price volatility of these investments are the
 less certain growth prospects of smaller firms and the lower degree of
 liquidity in the markets for such securities. Small capitalization companies
 and REITs may be thinly traded and may have to be sold at a discount from
 current market prices or in small lots over an extended period of time. In
 addition, these securities are subject to the risk that during certain peri-
 ods the liquidity of particular issuers or industries, or all securities in
 these investment categories, will shrink or disappear suddenly and without
 warning as a result of adverse economic or market conditions, or adverse
 investor perceptions, whether or not accurate. Because of the lack of suffi-
 cient market liquidity, an Underlying Fund may incur losses because it will
 be required to effect sales at a disadvantageous time and only then at a
 substantial drop in price. Small capitalization companies and REITs also
 often have limited product lines, markets or financial resources; may depend
 on or use a few key personnel for management; and may be susceptible to
 losses and risks of bankruptcy. Transaction costs for these investments are
 often higher than those for larger capitalization companies. Investments in
 small capitalization companies and REITs may be more difficult to price pre-
 cisely than other types of securities because of their characteristics and
 lower trading volumes.
 
 Risks of Derivative Investments. An Underlying Fund's transactions, if any,
 in options, futures, options on futures, swaps, interest rate caps, floors
 and collars, structured securities, inverse floating-rate securities,
 stripped mortgage-backed securities and currency transactions involve addi-
 tional risk of loss. Loss can result from a lack of correlation between
 changes in the value of derivative instruments and the portfolio assets (if
 any) being hedged, the potential illiquidity of the markets for derivative
 instruments, or the risks arising from margin requirements and related lev-
 erage factors associated with such transactions. The use of these management
 techniques also involves the risk of loss if the investment adviser is
 incorrect in its expectation of fluctuations in securities prices, interest
 rates or currency prices. The Underlying Funds may also invest in derivative
 investments for non-hedging purposes (that is, to seek to increase total
 return), which is considered as a speculative practice and presents even
 greater risk of loss.
 
 Derivative mortgage-backed securities (such as principal-only ("POs"),
 interest-only ("IOs") or inverse floating rate securities) are particularly
 exposed to call and extension risks. Small changes in mortgage prepayments
 can significantly impact
 
                                                                            9-NN
<PAGE>
 
 
 the cash flow and the market value of these securities. In general, the risk
 of faster than anticipated prepayments adversely affects IOs, super floaters
 and premium priced mortgage-backed securities. The risk of slower than
 anticipated prepayments generally adversely affects POs, floating-rate secu-
 rities subject to interest rate caps, support tranches and discount priced
 mortgage-backed securities. In addition, particular derivative securities
 may be leveraged such that their exposure (i.e., price sensitivity) to
 interest rate and/or prepayment risk is magnified.
 
 Floating-rate derivative debt securities can present more complex types of
 derivative and interest rate risks. For example, range floaters are subject
 to the risk that the coupon will be reduced below market rates if a desig-
 nated interest rate floats outside of a specified interest rate band or col-
 lar. Dual index or yield curve floaters are subject to lower prices in the
 event of an unfavorable change in the spread between two designated interest
 rates.
 
 Risks of Foreign Investments. Certain of the Underlying Funds may invest in
 foreign securities in accordance with their investment objectives and poli-
 cies. Foreign investments involve special risks that are not typically asso-
 ciated with U.S. dollar denominated or quoted securities of U.S. issuers.
 Foreign investments may be affected by changes in currency rates, changes in
 foreign or U.S. laws or restrictions applicable to such investments and
 changes in exchange control regulations (e.g., currency blockage). A decline
 in the exchange rate of the currency (i.e., weakening of the currency
 against the U.S. dollar) in which a portfolio security is quoted or denomi-
 nated relative to the U.S. dollar would reduce the value of the portfolio
 security.
 
 The introduction of a single currency, the euro, on January 1, 1999 for par-
 ticipating nations in the European Economic and Monetary Union presents
 unique uncertainties, including the legal treatment of certain outstanding
 financial contracts after January 1, 1999 that refer to existing currencies
 rather than the euro; the establishment and maintenance of exchange rates
 for currencies being converted into the euro; the fluctuation of the euro
 relative to non-euro currencies during the transition period from January 1,
 1999 to December 31, 2001 and beyond; whether the interest rate, tax and
 labor regimes of European countries participating in the euro will converge
 over time; and whether the conversion of the currencies of other countries
 in the European Union ("EU"), such as the United Kingdom and Denmark, into
 the euro and the admission of other non-EU countries such as Poland, Latvia
 and Lithuania as members of the EU may have an impact on the euro. These or
 other factors, including political and economic risks, could cause market
 disruptions, and could adversely affect the value of securities held by the
 Underlying Funds.
 
 Brokerage commissions, custodial services and other costs relating to
 investment in international securities markets generally are more expensive
 than in the United States.

                                                                      APPENDIX A
 
 In addition, clearance and settlement procedures may be different in foreign
 countries and, in certain markets, such procedures have been unable to keep
 pace with the volume of securities transactions, thus making it difficult to
 conduct such transactions.
 
 Foreign issuers are not generally subject to uniform accounting, auditing
 and financial reporting standards comparable to those applicable to U.S.
 issuers. There may be less publicly available information about a foreign
 issuer than about a U.S. issuer. In addition, there is generally less gov-
 ernment regulation of foreign markets, companies and securities dealers than
 in the United States. Foreign securities markets may have substantially less
 volume than U.S. securities markets and securities of many foreign issuers
 are less liquid and more volatile than securities of comparable domestic
 issuers. Furthermore, with respect to certain foreign countries, there is a
 possibility of nationalization, expropriation or confiscatory taxation,
 imposition of withholding or other taxes on dividend or interest payments
 (or, in some cases, capital gains), limitations on the removal of funds or
 other assets of the Underlying Funds, and political or social instability or
 diplomatic developments which could affect investments in those countries.
 
 Concentration of a Fund's assets in one of a few countries and currencies
 will subject a Fund to greater risks than if a Fund's assets were not geo-
 graphically concentrated.
 
 Investment in sovereign debt obligations involves risks not present in debt
 obligations of corporate issuers. The issuer of the debt or the governmental
 authorities that control the repayment of the debt may be unable or unwill-
 ing to repay principal or interest when due in accordance with the terms of
 such debt, and an Underlying Fund may have limited recourse to compel pay-
 ment in the event of a default. Periods of economic uncertainty may result
 in volatility of market prices of sovereign debt, and in turn the Underlying
 Fund's NAV, to a greater extent than the volatility inherent in debt obliga-
 tions of U.S. issuers.
 
 A sovereign debtor's willingness or ability to repay principal and pay
 interest in a timely manner may be affected by, among other factors, its
 cash flow situation, the extent of its foreign currency reserves, the avail-
 ability of sufficient foreign exchange on the date a payment is due, the
 relative size of the debt service burden to the economy as a whole, the sov-
 ereign debtor's policy toward international lenders, and the political
 constraints to which a sovereign debtor may be subject.
 
 Investments in foreign securities may take the form of sponsored and
 unsponsored American Depository Receipts ("ADRs") and Global Depository
 Receipts ("GDRs"). Certain Underlying Funds may also invest in European
 Depository Receipts ("EDRs") or other similar instruments representing secu-

 in a domestic bank or a correspondent bank. Prices of ADRs are quoted in
 U.S. dollars, and ADRs are traded in the United States. EDRs and GDRs are
 receipts evidencing an arrangement with a non-U.S. bank. EDRs and GDRs are
 not necessarily quoted in the same currency as the underlying security.
 
 Risks of Emerging Countries. Certain Underlying Funds may invest in securi-
 ties of issuers located in emerging countries. The risks of foreign invest-
 ment are heightened when the issuer is located in an emerging country. The
 International Equity, European Equity, International Small Cap, Emerging
 Markets Equity and Asia Growth Funds may each invest without limit in the
 securities of issuers in emerging countries. Up to 35% of the total assets
 of the Emerging Markets Equity Fund may be invested in securities of issuers
 in any one emerging country. The Growth and Income, Small Cap Value, Mid Cap
 Value, High Yield and CORE International Equity Funds may each invest up to
 25%, and the Core Fixed Income, Global Income and Capital Growth Funds may
 each invest up to 10%, of their respective total assets in securities of
 issuers in emerging countries.
 
 Foreign investment in the securities markets of certain emerging countries
 is restricted or controlled to varying degrees which may limit investment in
 such countries or increase the administrative costs of such investments. For
 example, certain Asian countries require governmental approval prior to
 investments by foreign persons or limit investment by foreign persons to
 only a specified percentage of an issuer's outstanding securities or a spe-
 cific class of securities which may have less advantageous terms (including
 price) than securities of the issuer available for purchase by nationals. In
 addition, certain countries may restrict or prohibit investment opportuni-
 ties in issuers or industries deemed important to national interests. Such
 restrictions may affect the market price, liquidity and rights of securities
 that may be purchased by a Fund. The repatriation of both investment income
 and capital from certain emerging countries is subject to restrictions such
 as the need for governmental consents. Due to restrictions on direct invest-
 ment in equity securities in certain Asian countries, such as Taiwan, it is
 anticipated that a Fund may invest in such countries only through other
 investment funds in such countries.
 
 Many emerging countries are subject to a substantial degree of economic,
 political and social instability. Governments of some emerging countries are
 authoritarian in nature or have been installed or removed as a result of
 military coups, while governments in other emerging countries have periodi-
 cally used force to suppress civil dissent. Disparities of wealth, the pace
 and success of democratization, and ethnic, religious and racial disaffec-
 tion, among other factors, have also led to social unrest, violence and/or
 labor unrest in some emerging countries. Unanticipated political or social
 developments may result in sudden and significant invest-

                                                                      APPENDIX A
 
 ment losses. Investing in emerging countries involves greater risk of loss
 due to expropriation, nationalization, confiscation of assets and property
 or the imposition of restrictions on foreign investments and on repatriation
 of capital invested.
 
 Many emerging countries have experienced currency devaluations and substan-
 tial (and, in some cases, extremely high) rates of inflation, which have had
 a negative effect on the economies and securities markets of such emerging
 countries. Economies in emerging countries generally are dependent heavily
 upon commodity prices and international trade and, accordingly, have been
 and may continue to be affected adversely by the economies of their trading
 partners, trade barriers, exchange controls, managed adjustments in relative
 currency values and other protectionist measures imposed or negotiated by
 the countries with which they trade.
 
 An Underlying Fund's investment in emerging countries may also be subject to
 withholding or other taxes, which may be significant and may reduce the
 return from an investment in such country to the Underlying Fund.
 
 Settlement procedures in emerging countries are frequently less developed
 and reliable than those in the United States and often may involve an Under-
 lying Fund's delivery of securities before receipt of payment for their
 sale. In addition, significant delays are common in certain markets in reg-
 istering the transfer of securities. Settlement or registration problems may
 make it more difficult for an Underlying Fund to value its portfolio securi-
 ties and could cause the Underlying Fund to miss attractive investment
 opportunities, to have a portion of its assets uninvested or to incur losses
 due to the failure of a counterparty to pay for securities the Underlying
 Fund has delivered or the Underlying Fund's inability to complete its con-
 tractual obligations. The creditworthiness of the local securities firms
 used by the Underlying Fund in emerging countries may not be as sound as the
 creditworthiness of firms used in more developed countries, thus subjecting
 the Underlying Fund to a greater risk of loss if a securities firm defaults
 in the performance of its responsibilities.
 
 The small size and inexperience of the securities markets in certain emerg-
 ing countries and the limited volume of trading in securities in those coun-
 tries may make an Underlying Fund's investments in such countries less liq-
 uid and more volatile than investments in countries with more developed
 securities markets (such as the United States, Japan and most Western Euro-
 pean countries). An Underlying Fund's investments in emerging countries are
 subject to the risk that the liquidity of a particular investment, or
 investments generally, in such countries will shrink or disappear suddenly
 and without warning as a result of adverse economic, market or political
 conditions, or adverse investor perceptions, whether or not accurate.
 Because of the lack of sufficient market liquidity, an Underlying Fund may
 incur losses because it will be required to effect sales at a disadvanta-
 geous time
 
                                                                           13-NN
<PAGE>
 
 
 and only then at a substantial drop in price. Investments in emerging coun-
 tries may be more difficult to price precisely because of their characteris-
 tics and lower trading volumes.
 
 An Underlying Fund's use of foreign currency management techniques in emerg-
 ing countries may be limited. Due to the limited market for these instru-
 ments in emerging countries, the Investment Adviser does not currently
 anticipate that a significant portion of the Funds' currency exposure in
 emerging countries, if any, will be covered by such instruments.
 
 Risks of Illiquid Securities. The Underlying Funds may invest up to 15% (10%
 in the case of the Financial Square Prime Obligations Fund) of its net
 assets in illiquid securities which cannot be disposed of in seven days in
 the ordinary course of business at fair value. Illiquid securities include:
  ^Both domestic and foreign securities that are not readily marketable
  ^Certain municipal leases and participation interests
  ^Certain stripped mortgage-backed securities
  ^Repurchase agreements and time deposits with a notice or demand period of
   more than seven days
  ^Certain over-the-counter options
  ^Certain restricted securities, unless it is determined, based upon a
   review of the trading markets for a specific restricted security, that
   the restricted security is eligible for resale pursuant to Rule 144A
   under the Securities Act of 1933 ("144A Securities") and, therefore, is
   liquid
 
 Investing in 144A Securities may decrease the liquidity of an Underlying
 Fund's portfolio to the extent that qualified institutional buyers become
 for a time uninterested in purchasing these restricted securities. The pur-
 chase price and subsequent valuation of restricted and illiquid securities
 normally reflect a discount, which may be significant, from the market price
 of comparable securities for which a liquid market exists.
 
 Risks of Non-Diversification and Concentration. The Global Income Fund is
 registered as a "non-diversified" Fund under the 1940 Act and is, therefore,
 more susceptible to adverse developments affecting any single issuer. In
 addition, the Global Income Fund, and certain other Underlying Funds, may
 invest more than 25% of their total assets in the securities of corporate
 and governmental issuers located in a particular foreign country or region.
 Concentration of a Fund's investments in such issuers will subject the Fund,
 to a greater extent than if investment was more limited, to the risks of
 adverse securities markets, exchange rates and social, political or economic
 events which may occur in that country or region.

 Temporary Investment Risks. Each Underlying Fund (other than the CORE Funds)
 may invest up to 100% of its total assets, and each CORE Fund may invest up
 to 35% of its total assets, in short-term debt securities. When an Under-
 lying Fund's assets are invested in such instruments, the Underlying Fund
 may not be achieving its investment objective.
 
 D. Investment Securities and Techniques
 
 U.S. Government Securities. The Underlying Funds may invest in U.S. Govern-
 ment Securities. Generally, these securities include U.S. Treasury obliga-
 tions and obligations issued or guaranteed by U.S. government agencies,
 instrumentalities or sponsored enterprises. U.S. Government Securities also
 include Treasury receipts and U.S. Government Securities that have been
 stripped by the U.S. Government, where the interest and principal components
 of the securities are traded independently. Interests in U.S. Government
 Securities may be purchased in the form of custodial receipts.
 
 Mortgage-Backed Securities. The Underlying Funds (other than the five CORE
 Equity Funds) may invest in so-called "Mortgage-Backed Securities." These
 securities represent direct or indirect participations in, or are collater-
 alized by and payable from, mortgage loans secured by real property.
 Mortgage-Backed Securities can be backed by either fixed rate mortgage loans
 or adjustable rate mortgage loans, and may be issued by either a governmen-
 tal or non-governmental entity. Privately issued Mortgage-Backed Securities
 are normally structured with one or more types of "credit enhancement." How-
 ever, these Mortgage-Backed Securities typically do not have the same credit
 standing as U.S. government guaranteed Mortgage-Backed Securities.
 
 Mortgage-Backed Securities may include multiple class securities, including
 collateralized mortgage obligations ("CMOs"), real estate mortgage invest-
 ment conduit ("REMIC") pass-through or participation certificates and
 stripped mortgage-backed securities ("SMBS"). CMOs provide an investor with
 a specified interest in the cash flow from a pool of underlying mortgages or
 of other Mortgage-Backed Securities. CMOs are issued in multiple classes. In
 most cases, payments of principal are applied to the CMO classes in the
 order of their respective stated maturities, so that no principal payments
 will be made on a CMO class until all other classes having an earlier stated
 maturity date are paid in full. A REMIC is a CMO that qualifies for special
 tax treatment and invests in certain mortgages principally secured by inter-
 ests in real property and other permitted investments. SMBS are derivative
 multiple class Mortgage-Backed Securities. The market value of SMBS consist-
 ing entirely of principal payments generally is unusually volatile in
 response to changes in interest rates. The yields on SMBS that receive all
 or most of the interest from mortgage
 
                                                                           15-NN
<PAGE>
 
 
 loans 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.
 
 Asset-Backed Securities. The Underlying Funds (other than the five CORE
 Equity Funds) may also invest in asset-backed securities. Certain Funds'
 Asset-Backed securities are limited to securities that are issued or guaran-
 teed by U.S. government agencies, instrumentalities or sponsored enter-
 prises. Asset-backed securities are securities whose principal and interest
 payments are collateralized by pools of assets such as auto loans, credit
 card receivables, leases, installment contracts and personal property.
 Asset-backed securities are often subject to more rapid repayment than their
 stated maturity date would indicate as a result of the pass-through of pre-
 payments of principal on the underlying loans. During periods of declining
 interest rates, prepayment of loans underlying asset-backed securities can
 be expected to accelerate. Accordingly, an Underlying Fund's ability to
 maintain positions in such securities will be affected by reductions in the
 principal amount of such securities resulting from prepayments, and its
 ability to reinvest the returns of principal at comparable yields is subject
 to generally prevailing interest rates at that time. Asset-backed securities
 present credit risks that are not presented by Mortgage-Backed Securities.
 This is because asset-backed securities generally do not have the benefit of
 a security interest in collateral that is comparable in quality to mortgage
 assets. There is the possibility that, in some cases, recoveries on
 repossessed collateral may not be available to support payments on these
 securities. In the event of a default, an Underlying Fund may suffer a loss
 if it cannot sell collateral quickly and receive the amount it is owed.
 
 Municipal Securities. Certain Underlying Funds may make limited investments
 in instruments issued by state and local governmental issuers. These securi-
 ties may include private activity bonds, municipal leases, certificates of
 participation and "auction rate" securities.
 
 Corporate Debt Obligations; Trust Preferred Securities; Convertible Securi-
 ties. The Underlying Funds may invest in corporate debt obligations, trust
 preferred securities and convertible securities. Corporate debt obligations
 include bonds, notes, debentures and other obligations of corporations to
 pay interest and repay principal, and include securities issued by banks and
 other financial institutions. A trust preferred or capital security is a
 long dated bond (for example, 30 years) with preferred features. The pre-
 ferred features are that payment of interest can be deferred for a specified
 period without initiating a default event. The securities are generally
 senior in claim to standard preferred stock but junior to other bondholders.

 Convertible securities are preferred stock or debt obligations that are con-
 vertible into common stock. Convertible securities generally offer lower
 interest or dividend yields than nonconvertible securities of similar quali-
 ty. Convertible securities in which an Underlying Fund invests are subject
 to the same rating criteria as its other investments in fixed-income securi-
 ties. Convertible securities have both equity and fixed-income risk charac-
 teristics. Like all fixed-income securities, the value of convertible secu-
 rities is susceptible to the risk of market losses attributable to changes
 in interest rates. Generally, the market value of convertible securities
 tends to decline as interest rates increase and, conversely, to increase as
 interest rates decline. However, when the market price of the common stock
 underlying a convertible security exceeds the conversion price of the con-
 vertible security, the convertible security tends to reflect the market
 price of the underlying common stock. As the market price of the underlying
 common stock declines, the convertible security, like a fixed-income securi-
 ty, tends to trade increasingly on a yield basis, and thus may not decline
 in price to the same extent as the underlying common stock.
 
 Zero Coupon, Deferred Interest, Pay-In-Kind and Capital Appreciation Bonds.
 Each Underlying Fund may invest in zero coupon, deferred interest, pay-in-
 kind and capital appreciation bonds. These securities are issued at a dis-
 count from their face value because interest payments are typically post-
 poned until maturity. Pay-in-kind securities are securities that have
 interest payable by the delivery of additional securities.The market prices
 of these securities generally are more volatile than the market prices of
 interest-bearing securities and are likely to respond to a greater degree to
 changes in interest rates than interest-bearing securities having similar
 maturities and credit quality.
 
 Rating Criteria. The rating requirements for each of the Underlying Fixed-
 Income Funds are stated above. Except as noted below, the Underlying Equity
 Funds (other than the five CORE Equity Funds, which only invest in debt
 instruments that are cash equivalents) may invest in debt securities rated
 at least investment grade at the time of investment. Investment grade debt
 securities are securities rated BBB or higher by Standard & Poor's or Baa or
 higher by Moody's. The Growth and Income, Capital Growth, Small Cap Value,
 International Equity, Japanese Equity, European Equity, International Small
 Cap, Emerging Markets Equity, Asia Growth and Real Estate Securities Funds
 may invest up to 10%, 10%, 35%, 35%, 35%, 35%, 35%, 35%, 35% and 20%,
 respectively, of their total assets in debt securities which are rated in
 the lowest rating categories by Standard & Poor's or Moody's (i.e., BB or
 lower by Standard & Poor's or Ba or lower by Moody's), including securities
 rated D by Moody's or Standard & Poor's. The Mid Cap Value Fund may invest
 up to 10% of its total assets in below investment grade debt securities
 rated B or higher by Standard & Poor's or Moody's. Fixed-
 
                                                                           17-NN
<PAGE>
 
 
 income securities rated BB or Ba or below (or comparable unrated securities)
 are commonly referred to as "junk bonds," are considered predominately spec-
 ulative and may be questionable as to principal and interest payments as
 described above.
 
 Structured Securities and Inverse Floaters. The Underlying Funds may invest
 in structured securities. Structured securities are securities whose value
 is determined by reference to changes in the value of specific currencies,
 interest rates, commodities, indices or other financial indicators (the
 "Reference") or the relative change in two or more References. The interest
 rate or the principal amount payable upon maturity or redemption may be
 increased or decreased depending upon changes in the applicable Reference.
 Structured securities may be positively or negatively indexed, so that
 appreciation of the Reference may produce an increase or decrease in the
 interest rate or value of the security at maturity. In addition, changes in
 the interest rates or the value of the security at maturity may be a multi-
 ple of changes in the value of the Reference. Consequently, structured secu-
 rities may present a greater degree of market risk than other types of
 fixed-income securities, and may be more volatile, less liquid and more dif-
 ficult to price accurately than less complex securities.
 
 Structured securities include, but are not limited to, inverse floating rate
 debt securities ("inverse floaters"). The interest rate on inverse floaters
 resets in the opposite direction from the market rate of interest to which
 the inverse floater is indexed. An inverse floater may be considered to be
 leveraged to the extent that its interest rate varies by a magnitude that
 exceeds the magnitude of the change in the index rate of interest. The
 higher the degree of leverage of an inverse floater, the greater the vola-
 tility of its market value.
 
 Foreign Currency Transactions. The Underlying Funds may, to the extent con-
 sistent with its investment policies, purchase or sell foreign currencies on
 a cash basis or through forward contracts. A forward contract involves an
 obligation to purchase or sell a specific currency at a future date at a
 price set at the time of the contract. A Fund may engage in foreign currency
 transactions for hedging purposes and to seek to protect against anticipated
 changes in future foreign currency exchange rates. In addition, certain
 Underlying Funds may also enter into such transactions to seek to increase
 total return, which is considered a speculative practice. Some Funds may
 also engage in cross-hedging by using forward contracts in a currency dif-
 ferent from that in which the hedged security is denominated or quoted if
 the investment adviser determines that there is a pattern of correlation
 between the two currencies. The Underlying Funds may hold foreign currency
 received in connection with investments in foreign securities when, in the
 judgment of its investment adviser, it would be beneficial to convert such
 currency into U.S. dollars at a later date.

 Currency exchange rates may fluctuate significantly over short periods of
 time causing, along with other factors, an Underlying Fund's value to fluc-
 tuate. Currency exchange rates also can be affected unpredictably by the
 intervention of U.S. or foreign governments or central banks, or the failure
 to intervene, or by currency controls or political developments in the
 United States or abroad.
 
 The market in forward foreign currency exchange contracts, currency swaps
 and other privately negotiated currency instruments offers less protection
 against defaults by the other party to such instruments than is available
 for currency instruments traded on an exchange. Such contracts are subject
 to the risk that the counterparty to the contract will default on its obli-
 gations. Since these contracts are not guaranteed by an exchange or clear-
 inghouse, a default on a contract would deprive an Underlying Fund of
 unrealized profits, or the benefits of a currency hedge, or could force the
 Underlying Fund to cover its purchase or sale commitments, if any, at the
 current market price.
 
 Options on Securities, Securities Indices and Foreign Currencies. A put
 option gives the purchaser of the option the right to sell, and the writer
 (seller) of the option the obligation to buy, the underlying instrument dur-
 ing the option period. A call option gives the purchaser of the option the
 right to buy, and the writer (seller) of the option the obligation to sell,
 the underlying instrument during the option period. Each Underlying Fund
 (other than the CORE U.S. Equity, CORE Large Cap Growth and CORE Large Cap
 Value Funds) may write (sell) covered call and put options and purchase put
 and call options on any securities in which it may invest or on any securi-
 ties index comprised of securities in which it may invest. An Underlying
 Fund, may also, to the extent it invests in foreign securities, purchase and
 sell (write) put and call options on foreign currencies.
 
 The writing and purchase of options is a highly specialized activity which
 involves special investment risks. Options may be used for either hedging or
 cross-hedging purposes, or to seek to increase total return (which is con-
 sidered a speculative activity). The successful use of options depends in
 part on the ability of an investment adviser to manage future price fluctua-
 tions and the degree of correlation between the options and securities (or
 currency) markets. If an investment adviser is incorrect in its expectation
 of changes in market prices or determination of the correlation between the
 instruments or indices on which options are written and purchased and the
 instruments in an Underlying Fund's investment portfolio, the Underlying
 Fund may incur losses that it would not otherwise incur. The use of options
 can also increase an Underlying Fund's transaction costs. Options written or
 purchased by the Underlying Funds may be traded on either U.S. or foreign
 exchanges or over-the-counter. Foreign and over-the-counter options will
 present greater possibility of loss because of their greater liquidity and
 credit risks.

 Futures Contracts and Options on Futures Contracts. Futures contracts are
 standardized, exchange-traded contracts that provide for the sale or pur-
 chase of a specified financial instrument or currency at a future time at a
 specified price. An option on a futures contract gives the purchaser the
 right (and the writer of the option the obligation) to assume a position in
 a futures contract at a specified exercise price within a specified period
 of time. A futures contract may be based on various securities (such as U.S.
 Government Securities), foreign currencies, securities indices and other
 financial instruments and indices. The Underlying Funds may engage in
 futures transactions on both U.S. and foreign exchanges.
 
 The Underlying Funds may purchase and sell futures contracts, and purchase
 and write call and put options on futures contracts, in order to seek to
 increase total return or to hedge against changes in interest rates, securi-
 ties prices or currency exchange rates, or to otherwise manage their term
 structures and durations in accordance with their investment objectives and
 policies. The Underlying Funds may also enter into closing purchase and sale
 transactions with respect to such contracts and options. An Underlying Fund
 will engage in futures and related options transactions for bona fide hedg-
 ing purposes as defined in regulations of the Commodity Futures Trading Com-
 mission or to seek to increase total return to the extent permitted by such
 regulations. The Underlying Funds may not purchase or sell futures contracts
 or purchase or sell related options to seek to increase total return, except
 for closing purchase or sale transactions, if immediately thereafter the sum
 of the amount of initial margin deposits and premiums paid on an Underlying
 Fund's outstanding positions in futures and related options entered into for
 the purpose of seeking to increase total return would exceed 5% of the mar-
 ket value of an Underlying Fund's net assets. Futures contracts and related
 options present the following risks:
 
^While an Underlying Fund may benefit from the use of futures and options on
 futures, unanticipated changes in interest rates, securities prices or cur-
 rency exchange rates may result in a poorer overall performance than if the
 Fund had not entered into any futures contracts or options transactions.
 
^Because perfect correlation between a futures position and portfolio position
 that is intended to be protected is impossible to achieve, the desired pro-
 tection may not be obtained and an Underlying Fund may be exposed to addi-
 tional risk of loss.
 
^The loss incurred by an Underlying Fund in entering into futures contracts
 and in writing call options on futures is potentially unlimited and may
 exceed the amount of the premium received.

^Futures markets are highly volatile and the use of futures may increase the
 volatility of an Underlying Fund's NAV.
 
^As a result of the low margin deposits normally required in futures trading,
 a relatively small price movement in a futures contract may result in sub-
 stantial losses to an Underlying Fund.
 
^Futures contracts and options on futures may be illiquid, and exchanges may
 limit fluctuations in futures contract prices during a single day.
 
 ^Foreign exchanges may not provide the same protection as U.S. exchanges.
 
 Preferred Stock, Warrants and Rights. The Underlying Funds may invest in
 preferred stock, warrants and rights. Preferred stocks are securities that
 represent an ownership interest providing the holder with claims on the
 issuer's earnings and assets before common stock owners but after bond own-
 ers. Unlike debt securities, the obligations of an issuer of preferred
 stock, including dividend and other payment obligations, may not typically
 be accelerated by the holders of such preferred stock on the occurrence of
 an event of default or other non-compliance by the issuer of the preferred
 stock. Warrants and other rights are options to buy a stated number of
 shares of common stock at a specified price at any time during the life of
 the warrant. The holders of warrants and rights have no voting rights,
 receive no dividends and have no rights with respect to the assets of the
 issuer.
 
 Real Estate Investment Trusts ("REITs"). The Real Estate Securities Fund
 expects to invest a substantial portion of its total assets in REITs, which
 are pooled investment vehicles that invest primarily in either real estate
 or real estate related loans. In addition, other Underlying Equity Funds may
 invest in REITs from time to time. The value of a REIT is affected by
 changes in the value of the properties owned by the REIT or securing mort-
 gage loans held by the REIT. REITs are dependent upon the ability of the
 REITs' managers, and are subject to heavy cash flow dependency, default by
 borrowers and the qualification of the REITs under applicable regulatory
 requirements for favorable federal income tax treatment. REITs are also sub-
 ject to risks generally associated with investments in real estate including
 possible declines in the value of real estate, general and local economic
 conditions, environmental problems and changes in interest rates. To the
 extent that assets underlying a REIT are concentrated geographically, by
 property type or in certain other respects, these risks may be heightened.
 Each Underlying Fund will indirectly bear its proportionate share of any
 expenses, including management fees, paid by a REIT in which it invests.
 
 Standard and Poor's Depository Receipts. Each Underlying Equity Fund may,
 consistent with its investment policies, purchase Standard & Poor's Deposi-
 tory
 
                                                                           21-NN
<PAGE>
 
 
 Receipts ("SPDRs"). SPDRs are American Stock Exchange-traded securities that
 represent ownership in the SPDR Trust, a trust which has been established to
 accumulate and hold a portfolio of common stocks that is intended to track
 the price performance and dividend yield of the S&P 500. The SPDR Trust is
 sponsored by a subsidiary of the American Stock Exchange. SPDRs may be used
 for several reasons, including, but not limited to, facilitating the han-
 dling of cash flows or trading or reducing transaction costs. The price
 movement of SPDRs may not perfectly parallel the price action of the S&P
 500.
 
 World Equity Benchmark Shares. World Equity Benchmark Shares ("WEBS") are
 shares of an investment company that invests substantially all of its assets
 in securities included in the MSCI indices for specified countries. WEBS are
 listed on the American Stock Exchange (the "AMEX"), and were initially
 offered to the public in 1996. The market prices of WEBS are expected to
 fluctuate in accordance with both changes in the net asset values of their
 underlying indices and supply and demand of WEBS on the AMEX. To date, WEBS
 have traded at relatively modest discounts and premiums to their net asset
 values. However, WEBS have a limited operating history, and information is
 lacking regarding the actual performance and trading liquidity of WEBS for
 extended periods or over complete market cycles. In addition, there is no
 assurance that the requirements of the AMEX necessary to maintain the list-
 ing of WEBS will continue to be met or will remain unchanged. In the event
 substantial market or other disruptions affecting WEBS should occur in the
 future, the liquidity and value of an Underlying Fund's shares could also be
 substantially and adversely affected, and the Underlying Fund's ability to
 provide investment results approximating the performance of securities in
 the EAFE Index could be impaired. If such disruptions were to occur, an
 Underlying Fund could be required to reconsider the use of WEBS as part of
 its investment strategy.
 
 Other Investment Companies. An Underlying Fund may invest in securities of
 other investment companies subject to the limitations prescribed by the
 Investment Company Act. These limitations include a prohibition on any Fund
 acquiring more than 3% of the voting shares of any other investment company,
 and a prohibition on investing more than 5% of an Underlying Fund's total
 assets in securities of any one investment company or more than 10% of its
 total assets in securities of all investment companies. An Underlying Fund
 will indirectly bear its proportionate share of any management fees and
 other expenses paid by such other investment companies. Such other invest-
 ment companies will have investment objectives, policies and restrictions
 substantially similar to those of the acquiring Fund and will be subject to
 substantially the same risks.
 
 Equity Swaps. Each Underlying Equity Fund may invest up to 10% of its total
 assets in equity swaps. Equity swaps allow the parties to a swap agreement

 exchange the dividend income or other components of return on an equity
 investment (e.g., a group of equity securities or an index) for a component
 of return on another non-equity or equity investment.
 
 An equity swap may be used by an Underlying Fund to invest in a market with-
 out owning or taking physical custody of securities in circumstances in
 which direct investment may be restricted for legal reasons or is otherwise
 impractical. Equity swaps are derivatives and their value can be very vola-
 tile. To the extent that an investment adviser does not accurately analyze
 and predict the potential relative fluctuation of the components swapped
 with another party, an Underlying Fund may suffer a loss. The value of some
 components of an equity swap (such as the dividends on a common stock) may
 also be sensitive to changes in interest rates. Furthermore, an Underlying
 Fund may suffer a loss if the counterparty defaults.
 
 When-Issued Securities and Forward Commitments. When-issued securities are
 securities that have been authorized, but not yet issued. When-issued secu-
 rities are purchased in order to secure what is considered to be an advanta-
 geous price and yield to an Underlying Fund at the time of entering into the
 transaction. A forward commitment involves the entering into a contract to
 purchase or sell securities for a fixed price at a future date beyond the
 customary settlement period.
 
 The purchase of securities on a when-issued or forward commitment basis
 involves a risk of loss if the value of the security to be purchased
 declines before the settlement date. Conversely, the sale of securities on a
 forward commitment basis involves the risk that the value of the sold secu-
 rities may increase before the settlement date. Although an Underlying Fund
 will generally purchase securities on a when-issued or forward commitment
 basis with the intention of acquiring securities for its portfolio, an
 Underlying Fund may dispose of when-issued securities or forward commitments
 before settlement whenever its investment adviser deems it appropriate.
 
 Repurchase Agreements. Repurchase agreements involve the purchase of securi-
 ties subject to the seller's agreement to repurchase them at a mutually
 agreed upon date and price. Each Underlying Fund may enter into repurchase
 agreements with dealers in U.S. Government Securities and member banks of
 the Federal Reserve System which furnish collateral at least equal in value
 or market price to the amount of their repurchase obligation. Some Under-
 lying Funds may also enter into repurchase agreements involving certain for-
 eign government securities. If the other party or "seller" defaults, an
 Underlying Fund might suffer a loss to the extent that the proceeds from the
 sale of the underlying securities and other collateral held by the Under-
 lying Fund in connection with the repurchase agreements are less than the
 repurchase price and the cost of the Underlying Fund associated with delay
 and enforcement of the repurchase agreement. In addition, in the event of
 
                                                                           23-NN

 bankruptcy of the seller, an Underlying Fund could suffer additional losses
 if a court determines that the Underlying Fund's interest in the collateral
 is not enforceable.
 
 In evaluating whether to enter into a repurchase agreement, the Investment
 Adviser will carefully consider the creditworthiness of the seller. Distri-
 butions of the income from repurchase agreements will be taxable to an
 Underlying Fund's shareholders. In addition, certain Underlying Funds,
 together with other registered investment companies having advisory agree-
 ments with the Investment Adviser or any of its affiliates, may transfer
 uninvested cash balances into a single joint account, the daily aggregate
 balance of which will be invested in one or more repurchase agreements.
 
 Lending of Portfolio Securities. Securities lending involves the lending of
 securities owned by an Underlying Fund to financial institutions such as
 certain broker-dealers. The borrowers are required to secure their loans
 continuously with cash, cash equivalents, U.S. Government Securities or let-
 ters of credit in an amount at least equal to the market value of the secu-
 rities loaned. Cash collateral may be invested in cash equivalents. If an
 investment adviser determines to make securities loans, the value of the
 securities loaned may not exceed 33 1/3% of the value of the total assets of
 an Underlying Fund (including the loan collateral).
 
 An Underlying Fund may lend its securities to increase its income. An Under-
 lying Fund may, however, experience delay in the recovery of its securities
 or possible loss if the institution with which it has engaged in a portfolio
 loan transaction breaches its agreement with the Underlying Fund.
 
 Short Sales Against-the-Box. Certain Underlying Funds may make short sales
 against-the-box. A short sale against-the-box means that at all times when a
 short position is open the Underlying Fund will own an equal amount of secu-
 rities sold short, or securities convertible into or exchangeable for, with-
 out the payment of any further consideration, an equal amount of the securi-
 ties of the same issuer as the securities sold short.
 
 Mortgage Dollar Rolls. The Underlying Fixed-Income Funds (except the High
 Yield Fund) and the Real Estate Securities Fund may enter into "mortgage
 dollar rolls." A mortgage dollar roll involves the sale by an Underlying
 Fund of securities for delivery in the current month, simultaneously con-
 tracts with the same counterparty to repurchase substantially similar (same
 type, coupon and maturity) but not identical securities on a specified
 future date. During the roll period, the Underlying Fund loses the right to
 receive principal and interest paid on the securities sold. However, the
 Underlying Fund benefits to the extent of any difference between (a) the
 price received for the securities sold and (b) the lower forward price for
 the future purchase and/or fee income plus the interest earned on the

                                                                      APPENDIX A
 
 cash proceeds of the securities sold. Unless the benefits of a mortgage dol-
 lar roll exceed the income, capital appreciation and gain or loss due to
 mortgage prepayments that would have been realized on the securities sold as
 part of the roll, the use of this technique will diminish the performance of
 the Underlying Fund.
 
 Successful use of mortgage dollar rolls depends upon the Investment Advis-
 er's ability to predict correctly interest rates and mortgage prepayments.
 If the Investment Adviser is incorrect in its prediction, a Fund may experi-
 ence a loss. For financial reporting and tax purposes, the Funds treat mort-
 gage dollar rolls as two separate transactions: one involving the purchase
 of a security and a separate transaction involving a sale. The Funds do not
 currently intend to enter into mortgage dollar rolls that are accounted for
 as a financing and do not treat them as borrowings.
 
 Borrowings and Reverse Repurchase Agreements. The Underlying Funds can bor-
 row money from banks and enter into reverse repurchase agreements with banks
 and other financial institutions in amounts not exceeding one-third of its
 total assets. Reverse repurchase agreements involve the sale of securities
 held by an Underlying Fund subject to the Underlying Fund's agreement to
 repurchase them at a mutually agreed upon date and price (including inter-
 est). These transactions may be entered into as a temporary measure for
 emergency purposes or to meet redemption requests. Reverse repurchase agree-
 ments may also be entered into when the investment adviser expects that the
 interest income to be earned from the investment of the transaction proceeds
 will be greater than the related interest expense. Borrowings and reverse
 repurchase agreements involve leveraging. If the securities held by an
 Underlying Fund decline in value while these transactions are outstanding,
 the NAV of the Underlying Fund's outstanding shares will decline in value by
 proportionately more than the decline in value of the securities. In addi-
 tion, reverse repurchase agreements involve the risk that any interest
 income earned by an Underlying Fund (from the investment of the proceeds)
 will be less than the interest expense of the transaction, that the market
 value of the securities sold by an Underlying Fund will decline below the
 price the Underlying Fund is obligated to pay to repurchase the securities,
 and that the securities may not be returned to the Underlying Fund.
 
 Interest Rate Swaps, Mortgage Swaps, Credit Swaps, Currency Swaps and Inter-
 est Rate Caps, Floors and Collars. To the extent consistent with their
 investment policies, the Underlying Funds may enter into interest rate
 swaps, mortgage swaps, credit swaps, currency swaps and interest rate caps,
 floors and collars. Interest rate swaps involve the exchange by an Under-
 lying Fund with another party of their respective commitments to pay or
 receive interest, such as an exchange of fixed-rate payments for floating
 rate payments. Mortgage swaps are similar to interest
 
                                                                           25-NN

 rate swaps in that they represent commitments to pay and receive interest.
 The notional principal amount, however, is tied to a reference pool or pools
 of mortgages. Credit swaps involve the receipt of floating or fixed rate
 payments in exchange for assuming potential credit losses of an underlying
 security. Credit swaps give one party to a transaction the right to dispose
 of or acquire an asset (or group of assets), or the right to receive or make
 a payment from the other party, upon the occurrence of specified credit
 events. Currency swaps involve the exchange of the parties' respective
 rights to make or receive payments in specified currencies. The purchase of
 an interest rate cap entitles the purchaser, to the extent that a specified
 index exceeds a predetermined interest rate, to receive payment of interest
 on a notional principal amount from the party selling such interest rate
 cap. The purchase of an interest rate floor entitles the purchaser, to the
 extent that a specified index falls below a predetermined interest rate, to
 receive payments of interest on a notional principal amount from the party
 selling the interest rate floor. An interest rate collar is the combination
 of a cap and a floor that preserves a certain return within a predetermined
 range of interest rates.
 
 An Underlying Fund may enter into swap transactions for hedging purposes or
 to seek to increase total return. The use of interest rate, mortgage, credit
 and currency swaps, as well as interest rate caps, floors and collars, is a
 highly specialized activity which involves investment techniques and risks
 different from those associated with ordinary portfolio securities transac-
 tions. If the investment adviser is incorrect in its forecasts of market
 value, interest rates and currency exchange rates, the investment perfor-
 mance of an Underlying Fund would be less favorable than it would have been
 if these investment techniques were not used.
 
 Miscellaneous Techniques
 
 In addition to the techniques and investments described above, certain
 Underlying Funds may engage in the following techniques and investments: (i)
 yield curve options (Underlying Fixed-Income Funds and Real Estate Securi-
 ties Fund only); (ii) loan participations (High Yield Fund only); and (iii)
 unseasoned companies.

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

                INVESTMENT POLICIES AND PRACTICES OF THE SERIES


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

U.S. GOVERNMENT SECURITIES

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

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

CUSTODIAL RECEIPTS

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

BANK AND CORPORATE OBLIGATIONS

          Each Series (other than ILA Treasury Obligations Portfolio, ILA
Government Portfolio, ILA Federal Portfolio, ILA Treasury Instruments Portfolio,
FS Treasury Obligations Fund, FS Government Fund, FS Treasury Instruments Fund
and FS Federal Fund) may invest in commercial paper, including variable amount
master demand notes and asset-backed commercial paper.  Commercial paper
represents short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies, corporations, and finance companies.  The 

                                      -1-
<PAGE>
 
commercial paper purchased by the Series consists of direct U.S. dollar
denominated obligations of domestic or, in the case of ILA Money Market
Portfolio, FS Money Market Fund and FS Premium Fund, foreign issuers. Bank
obligations in which the Series may invest include certificates of deposit,
bankers' acceptances, fixed time deposits and bank notes. Certificates of
deposit are negotiable certificates issued against funds deposited in a
commercial bank for a definite period of time and earning a specified return.

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

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

          The ILA Prime Obligations Portfolio, ILA Money Market Portfolio, FS
Prime Obligations Fund, FS Premium Fund and FS Money Market Fund may invest in
other short-term obligations (including short-term funding agreements payable in
U.S. dollars and issued or guaranteed by U.S. corporations, foreign corporations
(with respect to the ILA Money Market Portfolio, FS Money Market Fund and FS
Premium Fund) or other entities.  A funding agreement is a contract between an
issuer and a purchaser that obligates the issuer to pay a guaranteed rate 

                                      -2-
<PAGE>
 
of interest on a principal sum deposited by the purchaser. Funding agreements
will also guarantee the return of principal and may guarantee a stream of
payments over time. A funding agreement has a fixed maturity date and may have
either a fixed or variable interest rate that is based on an index and
guaranteed for a set time period. Because there is no secondary market for these
investments, any such funding agreement purchased by a Series will be regarded
as illiquid.

Repurchase Agreements

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

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

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

          For purposes of the Act, and generally, for tax purposes, a repurchase
agreement is deemed to be a loan from the Series to the seller of the
Obligation.  It is not clear whether for other purposes a court would consider
the Obligation purchased by the Series subject to a repurchase agreement as
being owned by the Series or as being collateral for a loan by the Series to the
seller.

          If, in the event of bankruptcy or insolvency proceedings against the
seller of the Obligation, a court holds that the Series does not have a
perfected security interest in the Obligation, the Series may be required to
return the Obligation to the seller's estate and be treated as an unsecured
creditor of the seller.  As an unsecured creditor, a Series would be at risk of
losing some or all of the principal and income involved in the transaction.  To
minimize this risk, the Series utilize custodians and subcustodians that the
Adviser believes follow customary securities industry practice with respect to
repurchase agreements, and the Adviser analyzes the creditworthiness of the
obligor, in this case the seller of the Obligation.  But because of the legal
uncertainties, this risk, like others associated with repurchase agreements,
cannot be eliminated.

          Also, in the event of commencement of bankruptcy or insolvency
proceedings with respect to the seller of the Obligation before repurchase of
the Obligation under a repurchase 

                                      -3-
<PAGE>
 
agreement, a Series may encounter delay and incur costs before being able to
sell the security. Such a delay may involve loss of interest or a decline in the
price of the Obligation.

          Apart from risks associated with bankruptcy or insolvency proceedings,
there is also the risk that the seller may fail to repurchase the security.
However, if the market value of the Obligation subject to the repurchase
agreement becomes less than the repurchase price (including accrued interest),
the Series will direct the seller of the Obligation to deliver additional
securities so that the market value of all securities subject to the repurchase
agreement equals or exceeds the repurchase price.

          Certain repurchase agreements which mature in more than seven days can
be liquidated before the nominal fixed term on seven days or less notice.  Such
repurchase agreements will be regarded as liquid instruments.

          In addition, each Series (other than the ILA Treasury Instruments
Portfolio and FS Treasury Instruments Fund), together with other registered
investment companies having management agreements with the Adviser or any of its
affiliates, may transfer uninvested cash balances into a single joint account,
the daily aggregate balance of which will be invested in one or more repurchase
agreements.

Foreign Securities

          The ILA Money Market Portfolio, FS Money Market Fund and FS Premium
Fund may invest in foreign securities and in certificates of deposit, bankers'
acceptances and fixed time deposits and other obligations issued by major
foreign banks which have more than $1 billion in total assets at the time of
purchase, foreign branches of U.S. banks, U.S. branches of foreign banks and
foreign branches of foreign banks.  The ILA Tax-Exempt Diversified Portfolio,
ILA Tax-Exempt California Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-
Free Fund and FS Municipal Fund may also invest in municipal instruments backed
by letters of credit issued by certain of such banks.  Under current Securities
and Exchange Commission ("SEC") rules relating to the use of the amortized cost
method of portfolio securities valuation, the ILA Money Market Portfolio, FS
Money Market Fund and FS Premium Fund are restricted to purchasing U.S. dollar
denominated securities, but it is not otherwise precluded from purchasing
securities of foreign issuers.

          Investments in foreign securities and bank obligations may involve
considerations different from investments in domestic securities due to limited
publicly available information; non-uniform accounting standards; the possible
imposition of withholding or confiscatory taxes; the possible adoption of
foreign governmental restrictions affecting the payment of principal and
interest; expropriation; or other adverse political or economic developments.
In addition, it may be more difficult to obtain and enforce a judgment against a
foreign issuer or a foreign branch of a domestic bank.

Asset-Backed and Receivables-Backed Securities

          The ILA Prime Obligations Portfolio, ILA Money Market Portfolio, FS
Prime Obligations Fund, FS Money Market Fund and FS Premium Fund may invest in
asset-backed and receivables-backed securities.  Asset-backed and receivables-
backed securities represent participations in, or are secured by and payable
from, pools of assets such as motor vehicle installment sale contracts,
installment loan contracts, leases of various types of real and personal
property, receivables from revolving credit (credit card) agreements, corporate
receivables and other categories of receivables.  Such asset pools are
securitized through the use of privately-formed trusts or special purpose
vehicles.  Payments or distributions of principal and interest may be guaranteed
up to certain amounts and for a certain time period by a letter of credit or a
pool insurance policy issued by a financial institution or other credit
enhancements may be present.  The value of a Series' investments in asset-backed
and receivables-backed securities may be adversely affected by prepayment of the
underlying obligations. In addition, the risk of prepayment may cause the value
of these investments to be more volatile than a Series' other investments.

          Through the use of trusts and special purpose corporations, various
types of assets, including automobile loans, computer leases, trade receivables
and credit card receivables, are being securitized in pass-through structures
similar to the mortgage pass-through structures.  Consistent with their
respective investment objectives and policies, the Series may invest in these
and other types of asset-backed securities that may be developed in the future.
This Statement of Additional Information will be amended or supplemented as
necessary to reflect the ILA Prime Obligations Portfolio, ILA Money Market
Portfolio, FS Prime Obligations Fund, FS Money Market Fund and FS Premium Fund
intention to invest in asset-backed securities with characteristics that are
materially different from the securities described in the preceding paragraph.
However, a Series will generally not invest in an asset-backed security if the
income received with respect to its investment constitutes rental income or
other income not treated as qualifying income under the 90% test described in
"Tax Information" below.  In general, the collateral supporting these securities
is of shorter maturity than mortgage loans and is less likely to experience
substantial prepayments in response to interest rate fluctuations.

          As set forth below, several types of asset-backed and receivables-
backed securities have already been offered to investors, including for example,
Certificates for Automobile Receivablessm ("CARSsm") and interests in pools of
credit card receivables.  CARSsm represent undivided fractional interests in a
trust ("CAR Trust") whose assets consist of a pool of motor vehicle retail
installment sales contracts and security interests in the vehicles securing the
contracts.  Payments of principal and interest on CARSsm are passed through
monthly to certificate holders, and are guaranteed up to certain amounts and for
a certain time period by a letter of credit issued by a financial institution
unaffiliated with the trustee or originator of the CAR Trust.  An investor's
return on CARSsm may be affected by early prepayment of principal on the
underlying vehicle sales contracts.  If the letter of credit is exhausted, the
CAR Trust may be prevented from realizing the full amount due on a sales
contract because of state law requirements and restrictions relating to
foreclosure sales of vehicles and the obtaining of deficiency judgments
following such sales or because of depreciation, damage or loss of a vehicle,
the application of federal and state bankruptcy and insolvency laws, or other
factors.  As 

                                      -5-
<PAGE>
 
a result, certificate holders may experience delays in payments or losses if the
letter of credit is exhausted.

          Asset-backed securities present certain risks that are not presented
by mortgage-backed securities.  Primarily, these securities may not have the
benefit of any security interest in the related assets.  Credit card receivables
are generally unsecured and the debtors are entitled to the protection of a
number of state and federal consumer credit laws, many of which give such
debtors the right to set off certain amounts owed on the credit cards, thereby
reducing the balance due.  There is the possibility that recoveries on
repossessed collateral may not, in some cases, be available to support payments
on these securities.

          Asset-backed securities are often backed by a pool of assets
representing the obligations of a number of different parties. To lessen the
effect of failures by obligors on underlying assets to make payments, the
securities may contain elements of credit support which fall into two
categories: (i) liquidity protection, and (ii) protection against losses
resulting from ultimate default by an obligor or servicer. Liquidity protection
refers to the provision of advances, generally by the entity administering the
pool of assets, to ensure that the receipt of payments on the losses results
from payment of the insurance obligations on at least a portion of the assets in
the pool. This protection may be provided through guarantees, policies or
letters of credit obtained by the issuer or sponsor from third parties, through
various means of structuring the transactions or through a combination of such
approaches. The degree of credit support provided for each issue is generally
based on historical information reflecting the level of credit risk associated
with the underlying assets. Delinquency or loss in excess of that anticipated or
failure of the credit support could adversely affect the value of or return on
an investment in such a security.

          The availability of asset-backed securities may be affected by
legislative or regulatory developments.  It is possible that such developments
could require the ILA Prime Obligations Portfolio, ILA Money Market Portfolio,
FS Prime Obligations Fund, FS Money Market Fund and FS Premium Fund to dispose
of any then existing holdings of such securities.  To the extent consistent with
its investment objectives and policies, each of the ILA Prime Obligations
Portfolio, Money Market Portfolio, FS Prime Obligations Fund, FS Money Market
Fund and FS Premium Fund may invest in new types of mortgage related securities
and in other asset-backed securities that may be developed in the future.

Forward Commitments and When-Issued Securities

          Each Series may purchase securities on a when-issued basis or purchase
or sell securities on a forward commitment basis. These transactions involve a
commitment by the Series to purchase or sell securities at a future date.  The
price of the underlying securities (usually expressed in terms of yield) and the
date when the securities will be delivered and paid for (the settlement date)
are fixed at the time the transaction is negotiated.  When-issued purchases and
forward commitment transactions are negotiated directly with the other party,
and such commitments are not traded on exchanges, but may be traded over-the-
counter.

                                      -6-
<PAGE>
 
          A Series will purchase securities on a when-issued basis or purchase
or sell securities on a forward commitment basis only with the intention of
completing the transaction and actually purchasing or selling the securities.
If deemed advisable as a matter of investment strategy, however, a Series may
dispose of or renegotiate a commitment after entering into it.  A Series also
may sell securities it has committed to purchase before those securities are
delivered to the Series on the settlement date.  The Series may realize a
capital gain or loss in connection with these transactions; distributions from
any net capital gains would be taxable to its unitholders.  For purposes of
determining a Series' average dollar weighted maturity, the maturity of when-
issued or forward commitment securities will be calculated from the commitment
date.

          When a Series purchases securities on a when-issued or forward
commitment basis, the Series will segregate cash or liquid assets having a value
(determined daily) at least equal to the amount of the Series' purchase
commitments.  In the case of a forward commitment to sell portfolio securities
subject to such commitment, the Series will segregate the portfolio securities
while the commitment is outstanding.  These procedures are designed to ensure
that the Series will maintain sufficient assets at all times to cover its
obligations under when-issued purchases and forward commitments.

Variable Amount Master Demand Notes

          Each Series (other than the ILA Treasury Obligations Portfolio, ILA
Federal Portfolio, ILA Treasury Instruments Portfolio, FS Treasury Obligations
Fund, FS Federal Fund and FS Treasury Instruments Fund) may purchase variable
amount master demand notes.  These obligations permit the investment of
fluctuating amounts at varying rates of interest pursuant to direct arrangements
between a Series, as lender, and the borrower.  Variable amount master demand
notes are direct lending arrangements between the lender and borrower and are
not generally transferable, nor are they ordinarily rated.  A Series may invest
in them only if the Adviser believes that the notes are of comparable quality to
the other obligations in which that Series may invest.

Variable Rate and Floating Rate Obligations

          The interest rates payable on certain fixed income securities in which
a Series may invest are not fixed and may fluctuate based upon changes in market
rates.  A variable rate obligation has an interest rate which is adjusted at
predesignated periods in response to changes in the market rate of interest on
which the interest rate is based.  Variable and floating rate obligations are
less effective than fixed rate instruments at locking in a particular yield.
Nevertheless, such obligations may fluctuate in value in response to interest
rate changes if there is a delay between changes in market interest rates and
the interest reset date for the obligation.

          Each Series (other than the ILA Treasury Obligations Portfolio, ILA
Federal Portfolio, ILA Treasury Instruments Portfolio, FS Treasury Obligations
Fund, FS Federal Fund and FS Treasury Instruments Fund) may purchase variable
and floating rate demand instruments that are tax exempt municipal obligations
or other debt securities that possess a floating or variable interest rate
adjustment formula.  These instruments permit a Series to demand payment of the
principal balance plus unpaid accrued interest upon a specified number of days'
notice to the 

                                      -7-
<PAGE>
 
issuer or its agent. The demand feature may be backed by a bank letter of credit
or guarantee issued with respect to such instrument.

          The terms of the variable or floating rate demand instruments that a
Series may purchase provide that interest rates are adjustable at intervals
ranging from daily up to six months, and the adjustments are based upon current
market levels, the prime rate of a bank or other appropriate interest rate
adjustment index as provided in the respective instruments.  Some of these
instruments are payable on demand on a daily basis or on not more than seven
days' notice.   Others, such as instruments with quarterly or semiannual
interest rate adjustments, may be put back to the issuer on designated days on
not more than thirty days' notice.  Still others are automatically called by the
issuer unless the Series instructs otherwise.  The Trust, on behalf of the
Series, intends to exercise the demand only (1) upon a default under the terms
of the debt security, (2) as needed to provide liquidity to a Series, (3) to
maintain the respective quality standards of a Series' investment portfolio, or
(4) to attain a more optimal portfolio structure.  A Series will determine the
variable or floating rate demand instruments that it will purchase in accordance
with procedures approved by the Trustees to minimize credit risks.  To be
eligible for purchase by a Series, a variable or floating rate demand instrument
which is unrated must have high quality characteristics similar to other
obligations in which the Series may invest.  The Adviser may determine that an
unrated variable or floating rate demand instrument meets a Series' quality
criteria by reason of being backed by a letter of credit, guarantee, or demand
feature issued by an entity that meets the quality criteria for the Series.
Thus, either the credit of the issuer of the obligation or the provider of the
credit support or both will meet the quality standards of the Series.

          As stated in the Prospectuses, the Series may consider the maturity of
a long-term variable or floating rate demand instrument to be shorter than its
ultimate stated maturity under specified conditions.  The acquisition of
variable or floating rate demand notes for a Series must also meet the
requirements of rules issued by the SEC applicable to the use of the amortized
cost method of securities valuation.  The Series will also consider the
liquidity of the market for variable and floating rate instruments, and in the
event that such instruments are illiquid, the Series' investments in such
instruments will be subject to the limitation on illiquid investments.

          A Series (other than ILA Treasury Obligations Portfolio, ILA Treasury
Instruments Portfolio, ILA Government Portfolio, ILA Federal Portfolio, FS
Treasury Obligations Fund, FS Government Fund, FS Treasury Instruments Fund and
FS Federal Fund) may invest in participation interests in variable or floating
rate tax-exempt obligations held by financial institutions (usually commercial
banks).  Such participation interests provide the Series with a specific
undivided interest (up to 100%) in the underlying obligation and the right to
demand payment of its proportional interest in the unpaid principal balance plus
accrued interest from the financial institution upon a specific number of days'
notice.  In addition, the participation interest generally is backed by an
irrevocable letter of credit or guarantee from the institution.  The financial
institution usually is entitled to a fee for servicing the obligation and
providing the letter of credit.

                                      -8-

Restricted and Other Illiquid Securities

          A Series may purchase securities that are not registered ("restricted
securities") under the Securities Act of 1933, as amended (the "1933 Act"),
including restricted securities that can be offered and sold to "qualified
institutional buyers" under Rule 144A under the 1933 Act.  However, a Series
will not invest more than 10% of the value of its net assets in securities which
are illiquid, which includes fixed time deposits maturing in more than seven
days that cannot be traded on a secondary market and restricted securities.  The
Board of Trustees has adopted guidelines under which the Adviser determines and
monitors the liquidity of restricted securities subject to the oversight of the
Trustees.  Restricted securities (including commercial paper issued pursuant to
Section 4(2) of the 1933 Act) which are determined to be liquid will not be
deemed to be illiquid investments for purposes of the foregoing restriction.
Since it is not possible to predict with assurance that the market for
restricted securities will continue to be liquid, the Adviser will carefully
monitor each Series' investments in these securities, focusing on such important
factors, among others, as valuation, liquidity and availability of information.
This investment practice could have the effect of increasing the level of
illiquidity in a Series to the extent that qualified institutional buyers become
for a time uninterested in purchasing these restricted securities.

Municipal Obligations

          The ILA Prime Obligations Portfolio, ILA Money Market Portfolio, ILA
Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California Portfolio, ILA Tax-
Exempt New York Portfolio, FS Prime Obligations Fund, FS Premium Fund, FS Money
Market Fund, FS Tax-Free Fund and FS Municipal Fund may invest in municipal
obligations.  Municipal obligations are issued by or on behalf of states,
territories and possessions of the United States and their political
subdivisions, agencies, authorities and instrumentalities and the District of
Columbia to obtain funds for various public purposes.  The interest on most of
these obligations is generally exempt from regular federal income tax.  The two
principal classifications of municipal obligations are "notes" and "bonds."

          As a matter of fundamental policy, at least 80% of each of the ILA
Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California Portfolio, ILA Tax-
Exempt New York Portfolio, FS Tax-Free Fund and FS Municipal Fund's net assets
will ordinarily be invested in municipal obligations, the interest from which is
in the opinion of bond counsel, if any, excluded from gross income for federal
income tax purposes.  In addition, as a matter of fundamental policy, at least
65% of each of the ILA Tax-Exempt California Portfolio and ILA Tax- Exempt New
York Portfolio's total assets will be invested in California and New York
municipal obligations, respectively, except in extraordinary circumstances.
Each Tax-Exempt Fund may temporarily invest in taxable money market instruments
or, in the case of the ILA Tax-Exempt California and ILA Tax-Exempt New York
Portfolio's, in municipal obligations that are not California or New York
municipal obligations, respectively, when acceptable California and New York
obligations are not available or when the Adviser believes that the market
conditions dictate a defensive posture.  Investments in taxable money market
instruments will be limited to those meeting the quality standards of each Tax-
Exempt Fund.  The ILA Prime Obligations Portfolio, ILA Money Market Portfolio,
FS Prime Obligations Fund, FS Money Market Fund and 

                                      -9-
<PAGE>
 
FS Premium Fund may also invest in municipal obligations when yields on such
securities are attractive compared to other taxable investments. The ILA Tax-
Exempt California and ILA Tax-Exempt New York Portfolios distributions of
interest from municipal obligations other than California and New York
obligations, respectively, may be subject to California and New York state and
New York city personal income taxes.

          Notes.   Municipal notes are generally used to provide for short-term
capital needs and generally have maturities of one year or less.  Municipal
notes include tax anticipation notes, revenue anticipation notes, bond
anticipation notes, tax and revenue anticipation notes, construction loan notes,
tax-exempt commercial paper and certain receipts for municipal obligations.

          Tax anticipation notes are sold to finance working capital needs of
municipalities.  They are generally payable from specific tax revenues expected
to be received at a future date.  They are frequently general obligations of the
issuer, secured by the taxing power for payment of principal and interest.
Revenue anticipation notes are issued in expectation of receipt of other types
of revenue such as federal or state aid.  Tax anticipation notes and revenue
anticipation notes are generally issued in anticipation of various seasonal
revenues such as income, sales, use, and business taxes.  Bond anticipation
notes are sold to provide interim financing in anticipation of long-term
financing in the market.  In most cases, these monies provide for the repayment
of the notes. Tax-exempt commercial paper consists of short-term unsecured
promissory notes issued by a state or local government or an authority or agency
thereof.  The Series which invest in municipal obligations may also acquire
securities in the form of custodial receipts which evidence ownership of future
interest payments, principal payments or both on certain state and local
governmental and authority obligations when, in the opinion of bond counsel, if
any, interest payments with respect to such custodial receipts are excluded from
gross income for federal income tax purposes, and in the case of the ILA Tax-
Exempt California and ILA Tax-Exempt New York Portfolios, exempt from California
and New York (city and state) personal income taxes, respectively.  Such
obligations are held in custody by a bank on behalf of the holders of the
receipts.  These custodial receipts are known by various names, including
"Municipal Receipts" ("MRs") and "Municipal Certificates of Accrual on Tax-
Exempt Securities" ("M-CATS").  There are a number of other types of notes
issued for different purposes and secured differently from those described
above.

          Bonds.  Municipal bonds, which generally meet longer term capital
needs and have maturities of more than one year when issued, have two principal
classifications, "general obligation" bonds and "revenue" bonds.

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

                                     -10-
<PAGE>
 
          Revenue bonds have been issued to fund a wide variety of capital
projects including:  electric, gas, water and sewer systems; highways, bridges
and tunnels; port and airport facilities; colleges and universities; and
hospitals.  The principal security for a revenue bond is generally the net
revenues derived from a particular facility or group of facilities or, in some
cases, from the proceeds of a special excise or other specific revenue source.
Although the principal security behind these bonds varies widely, many provide
additional security in the form of a debt service reserve fund whose monies may
also be used to make principal and interest payments on the issuer's
obligations. Housing finance authorities have a wide range of security including
partially or fully insured, rent subsidized and/or collateralized mortgages,
and/or the net revenues from housing or other public projects.  In addition to a
debt service reserve fund, some authorities provide further security in the form
of a state's ability (without obligation) to make up deficiencies in the debt
service reserve fund.  Lease rental revenue bonds issued by a state or local
authority for capital projects are secured by annual lease rental payments from
the state or locality to the authority sufficient to cover debt service on the
authority's obligations.

          Private activity bonds (a term that includes certain types of bonds
the proceeds of which are used to a specified extent for the benefit of persons
other than governmental units), although nominally issued by municipal
authorities, are generally not secured by the taxing power of the municipality
but are secured by the revenues of the authority derived from payments by the
industrial user.  Each Series (other than the ILA Treasury Obligations
Portfolio, ILA Treasury Instruments Portfolio, ILA Government Portfolio, ILA
Federal Portfolio, FS Treasury Obligations Fund, FS Treasury Instruments Fund,
FS Government and FS Federal Funds) may invest in private activity bonds.  The
FS Municipal Fund may invest up to 100% of its assets in private activity bonds.
The ILA Tax-Exempt New York Portfolio will limit its investments in private
activity bonds to not more than 20% of its net assets under normal market
conditions.  The ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio and FS Tax-Free Fund do not intend to invest in private activity bonds
if the interest from such bonds would be an item of tax preference to
unitholders under the federal alternative minimum tax.  If such policy should
change in the future, such investments would not exceed 20% of each of the ILA
Tax-Exempt Diversified, ILA Tax-Exempt California Portfolio's and the FS Tax-
Free Funds net assets under normal market conditions.

          Municipal bonds with a series of maturity dates are called serial
bonds.  The serial bonds which the Portfolios may purchase are limited to short-
term serial bonds---those with original or remaining maturities of thirteen
months or less.  The Series may purchase long-term bonds provided that they have
a remaining maturity of thirteen months or less or, in the case of bonds called
for redemption, the date on which the redemption payment must be made is within
thirteen months.  The Series may also purchase long-term bonds (sometimes
referred to as "Put Bonds"), which are subject to a Series' commitment to put
the bond back to the issuer at par at a designated time within thirteen months
and the issuer's commitment to so purchase the bond at such price and time.

          The Series which invest in municipal obligations may invest in tender
option bonds.  A tender option bond is a municipal obligation (generally held
pursuant to a custodial arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-term
tax-exempt rates.  The bond is typically issued in conjunction with the

                                     -11-
<PAGE>
 
agreement of a third party, such as a bank, broker-dealer or other financial
institution, pursuant to which such institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution and
receive the face value thereof.  As consideration for providing the option, the
financial institution receives periodic fees equal to the difference between the
bond's fixed coupon rate and the rate, as determined by a remarketing or similar
agent at or near the commencement of such period, that would cause the bond,
coupled with the tender option, to trade at par on the date of such
determination.  Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term, tax-
exempt rate.  However, an institution will not be obligated to accept tendered
bonds in the event of certain defaults by, or a significant downgrading in the
credit rating assigned to, the issuer of the bond.

          The tender option will be taken into consideration in determining the
maturity of tender option bonds and the average portfolio maturity of a Series.
The liquidity of a tender option bond is a function of the credit quality of
both the bond issuer and the financial institution providing liquidity.
Consequently, tender option bonds are deemed to be liquid unless, in the opinion
of the Adviser, the credit quality of the bond issuer and the financial
institution is deemed, in light of the relevant Series' credit quality
requirements, to be inadequate.

          Although the ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt
California Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-Free Fund and FS
Municipal Fund intend to invest in tender option bonds the interest on which
will, in the opinion of counsel for the issuer and sponsor or counsel selected
by the Adviser, be excluded from gross income for federal income tax purposes,
there is no assurance that the Internal Revenue Service will agree with such
counsel's opinion in any particular case.  Consequently, there is a risk that a
Series will not be considered the owner of such tender option bonds and thus
will not be entitled to treat such interest as exempt from such tax.  A similar
risk exists for certain other investments subject to puts or similar rights.
Additionally, the federal income tax treatment of certain other aspects of these
investments, including the proper tax treatment of tender options and the
associated fees, in relation to various regulated investment company tax
provisions is unclear.  The ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt
California Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-Free Fund and FS
Municipal Fund intend to manage their respective portfolios in a manner designed
to eliminate or minimize any adverse impact from the tax rules applicable to
these investments.

          In addition to general obligation bonds, revenue bonds and serial
bonds, there are a variety of hybrid and special types of municipal obligations
as well as numerous differences in the security of municipal obligations both
within and between the two principal classifications above.

          The ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-Free Fund and FS Municipal
Fund may purchase municipal instruments that are backed by letters of credit
issued by foreign banks that have a branch, agency or subsidiary in the United
States.  Such letters of credit, like other obligations of foreign banks, may
involve credit risks in addition to those of domestic obligations, including
risks relating to future political and economic developments, nationalization,
foreign 

                                     -12-
<PAGE>
 
governmental restrictions such as exchange controls and difficulties in
obtaining or enforcing a judgment against a foreign bank (including branches).

          For the purpose of investment restrictions of the Series, the
identification of the "issuer" of municipal obligations that are not general
obligation bonds is made by the Adviser on the basis of the characteristics of
the obligation as described above, the most significant of which is the source
of funds for the payment of principal of and interest on such obligations.

          An entire issue of municipal obligations may be purchased by one or a
small number of institutional investors such as one of the Series.  Thus, the
issue may not be said to be publicly offered.  Unlike securities which must be
registered under the 1933 Act prior to offer and sale, municipal obligations
which are not publicly offered may nevertheless be readily marketable.  A
secondary market may exist for municipal obligations which were not publicly
offered initially.

          Municipal obligations purchased for a Series may be subject to the
Series' policy on holdings of illiquid securities.  The Adviser determines
whether a municipal obligation is liquid based on whether it may be sold in a
reasonable time consistent with the customs of the municipal markets (usually
seven days) at a price (or interest rate) which accurately reflects its value.
The Adviser believes that the quality standards applicable to each Series'
investments enhance liquidity.  In addition, stand-by commitments and demand
obligations also enhance liquidity.

          Yields on municipal obligations depend on a variety of factors,
including money market conditions, municipal bond market conditions, the size of
a particular offering, the maturity of the obligation and the quality of the
issue.  High quality municipal obligations tend to have a lower yield than lower
rated obligations.  Municipal obligations are subject to the provisions of
bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Code, and laws, if any, which may be
enacted by Congress or state legislatures extending the time for payment of
principal or interest, or both, or imposing other constraints upon enforcement
of such obligations or municipalities to levy taxes.  There is also the
possibility that as a result of litigation or other conditions the power or
ability of any one or more issuers to pay when due principal of and interest on
its or their municipal obligations may be materially affected.

Investing in California

          The financial condition of the State of California ("California"), its
public authorities and local governments could affect the market values and
marketability of, and therefore the net asset value per unit and the interest
income of, the ILA Tax-Exempt California Portfolio, or result in the default of
existing obligations, including obligations which may be held by the ILA Tax-
Exempt California Portfolio.  The following section provides only a brief
summary of the complex factors affecting the financial condition of California,
and is based on information obtained from California, as publicly available
prior to the date of this Statement of Additional Information.  The information
contained in such publicly available documents has not been independently
verified.  It should be noted that the creditworthiness of obligations issued by
local issuers may be unrelated to the creditworthiness of California, and that
there is no obligation on 

                                     -13-
<PAGE>
 
the part of California to make payment on such local obligations in the event of
default in the absence of a specific guarantee or pledge provided by California.

          During the early 1990's, California experienced significant financial
difficulties, which reduced its credit standing, but the State's finances have
improved since 1995.  The ratings of certain related debt of other issuers for
which California has an outstanding lease purchase, guarantee or other
contractual obligation (such as for state-insured hospital bonds) are generally
linked directly to California's rating.  Should the financial condition of
California deteriorate again, its credit ratings could be further reduced, and
the market value and marketability of all outstanding notes and bonds issued by
California, its public authorities or local governments could be adversely
affected.

          Economic Factors.  California's economy is the largest among the 50
          ----------------                                                   
states (accounting for almost 13% of the nation's output of goods and services)
and one of the largest in the world. California's population of more than 32.9
million represents over 12% of the total United States population and grew by
27% in the 1980s.  While California's substantial population growth during the
1980's stimulated local economic growth and diversification and sustained a real
estate boom between 1984 and 1990, it increased strains on California's limited
water resources and demands for government services.  Population growth slowed
since 1991 even while substantial immigration has continued, due to a
significant increase in outmigration by California residents.  However, with the
California economy improving, the recent net outmigration within the Continental
U.S. is expected to decrease or be reversed.

          From mid-1990 to late 1993, California's economy suffered its worst
recession since the 1930s, with over 700,000 jobs lost.  The largest job losses
were in Southern California, led by declines in the aerospace and construction
industries.  These losses were significantly related to cuts in lost federal
defense spending.

          Since the start of 1994, the California economy has been in a steady
recovery in all parts of the State.  The State Department of Finance reports net
job growth, particularly in construction and related manufacturing, wholesale
and retail trade, electronics, exports, transportation, recreation and services.
This growth has offset the continuing but slowing job losses in the aerospace
industry and restructuring of the finance and utility sectors.  Prerecession job
levels were reached in 1996.  Unemployment in California is down more than three
percent from its 10% peak in January, 1994, but still remains higher than the
national average rate.

Constitutional Limitations on Taxes, Other Charges and Appropriations
- ---------------------------------------------------------------------

          Limitations on Property Taxes.   Certain California Instruments may be
          -----------------------------                                         
obligations of issuers which rely in whole or in part, directly or indirectly,
on ad valorem property taxes as a source of revenue.  The taxing power of
California local governments and districts is limited by Article XIIIA of the
California constitution, also known as "Proposition 13." Briefly, Article XIIIA
limits to 1% of full cash value the rate of ad valorem property taxes on real
property and generally restricts the reassessment of property to 2% per year,
except upon new construction or change of ownership (subject to a number of
exemptions).  Taxing entities may, however, raise ad valorem taxes above the 1%
limit to pay debt service on voter-approved bonded indebtedness.

                                     -14-
<PAGE>
 
          Under Article XIIIA, the basic 1% ad valorem tax levy is applied
against the assessed value of property as of the owner's date of acquisition (or
as of March 1, 1975, if acquired earlier), subject to certain adjustments.  This
system has resulted in widely varying amounts of tax on similarly situated
properties.  Several lawsuits have been filed challenging the acquisition-based
assessment system of Proposition 13, and on June 18, 1992 the U.S. Supreme Court
announced a decision upholding Proposition 13.

          Article XIIIA prohibits local governments from raising revenues
through ad valorem property taxes above the 1% limit; it also requires voters of
any governmental unit to give two-thirds approval to levy any "special tax."
Court decisions, however, allowed non-voter approved levy of "general taxes"
which were not dedicated to a specific use.  In response to these decisions, the
voters of the State in 1986 adopted an initiative statute which imposed
significant new limits on the ability of  local entities to raise or levy
general taxes, except by receiving majority local voter approval.  Significant
elements of this initiative, "Proposition 62," have been overturned in recent
court cases.  An initiative proposed to re-enact the provisions of Proposition
62 as a constitutional amendment was defeated by the voters in November 1990,
but such a proposal may be renewed in the future.

          Limitations on Other Taxes, Fees and Charges. On November 5, 1996, the
          --------------------------------------------                          
voters of the State approved Proposition 218, called the "Right to Vote on Taxes
Act."  Proposition 218 added Articles XIIIC and XIIID to the State Constitution,
which contain a number of provisions affecting the ability of local agencies to
levy and collect both existing and future taxes, assessments, fees and charges.

          Article XIIIC requires that all new or increased local taxes be
submitted to the electorate before they become effective.  Taxes for general
governmental purposes require a majority vote and taxes for specific purposes
require a two-thirds vote.  Further, any general purpose tax which was imposed,
extended or increased without voter approval after December 31, 1994 must be
approved by a majority vote within two years.

          Article XIIID contains several new provisions making it generally more
difficult for local agencies to levy and maintain "assessments" for municipal
services and programs.  Article XIIID also contains several new provisions
affecting "fees" and "charges," defined for purposes of Article XIIID to mean
"any levy other than an ad valorem tax, a special tax, or an assessment, imposed
by a [local government] upon a parcel or upon a person as an incident of
property ownership, including a user fee or charge for a property related
service."  All new and existing property related fees and charges must conform
to requirements prohibiting, among other things, fees and charges which generate
revenues exceeding the funds required to provide the property related service or
are used for unrelated purposes.  There are new notice, hearing and protest
procedures for levying or increasing property related fees and charges, and,
except for fees or charges for sewer, water and refuse collection services (or
fees for electrical and gas service, which are not treated as "property related"
for purposes of Article XIIID), no property related fee or charge may be imposed
or increased without majority approval by the property owners subject to the fee
or charge or, at the option of the local agency, two-thirds voter approval by
the electorate residing in the affected area.

                                     -15-
<PAGE>
 
          In addition to the provisions described above, Article XIIIC removes
limitations on the initiative power in matters of local taxes, assessments, fees
and charges.  Consequently, local voters could, by future initiative, repeal,
reduce or prohibit the future imposition or increase of any local tax,
assessment, fee or charge. It is unclear how this right of local initiative may
be used in cases where taxes or charges have been or will be specifically
pledged to secure debt issues.

          The interpretation and application of Proposition 218 will ultimately
be determined by the courts with respect to a number of matters, and it is not
possible at this time to predict with certainly the outcome of such
determinations.  Proposition 218 is generally viewed as restricting the fiscal
flexibility of local governments, and for this reason, some ratings of
California cities and counties have been, and others may be, reduced.

          Appropriation Limits.  The State and its local governments are subject
          --------------------                                                  
to an annual "appropriations limit" imposed by Article XIIIB of the California
Constitution, enacted by the voters in 1979 and significantly amended by
Propositions 98 and 111 in 1988 and 1990, respectively.  Article XIIIB prohibits
the State or any covered local government from spending "appropriations subject
to limitation" in excess of the appropriations limit imposed. "Appropriations
subject to limitation" are authorizations to spend "proceeds of taxes," which
consist of tax revenues and certain other funds, including proceeds from
regulatory licenses, user charges or other fees, to the extent that such
proceeds exceed the cost of providing the product or service, but "proceeds of
taxes" excludes most State subventions to local governments.  No limit is
imposed on appropriations of funds which are not "proceeds of taxes," such as
reasonable user charges or fees, and certain other non-tax funds, including bond
proceeds.

          Among the expenditures not included in the Article XIIIB
appropriations limit are (1) the debt service cost of bonds issued or authorized
prior to January 1, 1979, or subsequently authorized by the voters, (2)
appropriations arising from certain emergencies declared by the Governor, (3)
appropriations for certain capital outlay projects, (4) appropriations by the
State of post 1989 increases in gasoline taxes and vehicle weight fees, and (5)
appropriations made in certain cases of emergency.

          The appropriations limit for each year is adjusted annually to reflect
changes in cost of living and population and any transfer of service
responsibilities between governmental units.  The definitions for such
adjustments were liberalized in 1990 to follow more closely growth in the
State's economy.

          "Excess" revenues are measured over a two year cycle.  Local
governments must return any excess to taxpayers by rate reductions. The State
must refund 50% paid to schools and  community colleges. With more liberal
annual adjustment factors since 1988, and depressed revenues since 1990 because
of the recession, few governments, including the State, are currently operating
near their spending limits, but this condition may change over time. The State's
1997-98 Budget Act provides for State appropriations more than $6 billion under
the Article XIIIB limit. Local governments may by voter approval exceed their
spending limits for up to four years.

                                     -16-
<PAGE>
 
          Because of the complex nature of Articles XIIIA, XIIIB, XIIIC and
XIIID of the California Constitution, the ambiguities and possible
inconsistencies of their terms, and the impossibility of predicting future
appropriations or changes in population and cost of living, and the probability
of continuing legal  challenges, it is not currently possible to determine fully
the impact of these articles on California Instruments.  It is not presently
possible to predict the outcome of any pending litigation with respect to the
ultimate scope, impact or constitutionality of these articles, or the impact of
any such determinations upon State agencies or local governments, or upon their
ability to pay debt service or their obligations.  Future initiatives or
legislative changes in laws or the California Constitution may also affect the
ability of the State or local issuers to repay their obligations.

          State Debt.  Under the California Constitution, debt service on
          ----------                                                     
outstanding general obligation bonds is the second charge to the General Fund
after support of the public school system and public institutions of higher
education.  Total outstanding general obligation bonds and lease purchase debt
of California increased from $9.4 billion at June 30, 1987 to $24.9 billion at
February 1, 1998.  The State also had outstanding at February 1, 1998 $1.051
billion of general obligation commercial paper notes which will be refunded into
long-term bonds at a later date. In FY1996-97, debt service on general
obligation bonds and lease purchase debt was approximately 5.0% of General Fund
revenues.

          Recent Financial Results.   The principal sources of General Fund
          ------------------------                                         
revenues in 1996-1997 were the California personal income tax (47% of total
revenues), the sales tax (34%), bank and corporation taxes (12%), and the gross
premium tax on insurance (3%). California maintains a Special Fund for Economic
Uncertainties (the "SFEU"), derived from General Fund revenues, as a reserve to
meet cash needs of the General Fund.

          General.  Throughout the 1980s, California state spending increased
          -------                                                            
rapidly as California's population and economy also grew rapidly, including
increased spending for many assistance programs to local governments, which were
constrained by Proposition 13 and other laws.  The largest state program is
assistance to local public school districts.  In 1988, an initiative
(Proposition 98) was enacted which (subject to suspension by a two-thirds vote
of the Legislature and the Governor) guarantees local school districts and
community college districts a minimum share of California General Fund revenues
(currently about 35%).

          Beginning at the start of the 1990-91 Fiscal Year, California faced
adverse economic, fiscal and budget conditions.  The economic recession
seriously affected California's tax revenues.  It also caused increased
expenditures for health and welfare programs.

          Recent Budgets.  As a result of these factors, among others, from the
          --------------                                                       
late 1980's until 1992-93, the State had a period of nearly chronic budget
imbalance, with expenditures exceeding revenues in four out of six years, and
the State accumulated and sustained a budget deficit in the SFEU approaching
$2.8 billion at its peak at June 30, 1993.  For several years, each budget
required multibillion dollar actions to bring projected revenues and
expenditures into balance and to close large "budget gaps" which were
identified.  The Legislature and Governor eventually agreed on a number of
different steps to produce Budget Acts in the Fiscal Years 1991-92 to 1995-96,
including the following (not all of these actions were taken each year):

                                     -17-
<PAGE>
 
          .  significant cuts in health and welfare program expenditures;

          .  transfers of program responsibilities and some funding sources from
the State to local governments, coupled with some reduction in mandates on local
government;

          .  transfer of about $3.6 billion in annual local property tax
revenues from cities, counties, redevelopment agencies and some other districts
to local school districts, thereby reducing state funding for schools;

          .  reduction in growth of support for higher education programs,
coupled with increases in student fees;

          .  revenue increases (particularly in the 1991-92 Fiscal Year budget),
most of which were for a short duration;

          .  increased reliance on aid from the federal government to offset the
costs of incarcerating, educating and providing health and welfare services to
undocumented aliens (although these efforts have produced much less federal aid
than the State Administration had requested); and

          .  various one-time adjustment and accounting changes.

          The combination of stringent budget actions cutting State
expenditures, and the turnaround of the economy by late 1993, finally led to the
restoration of positive financial results, with revenues equaling or exceeding
expenditures starting in FY 1992-93.  As a result, the accumulated budget
deficit of about $2.8 billion was eliminated by June 30, 1997, when the State
showed a positive balance of about $408 million, on a budgetary basis, in the
SFEU.

          A consequence of the accumulated budget deficits in the early 1990's,
together with other factors such as disbursement of funds to local school
districts "borrowed" from future fiscal years and hence not shown in the annual
budget, was to significantly reduce the State's cash resources available to pay
its ongoing obligations.  The State's cash condition became so serious that from
late spring 1992 until 1995, the State had to rely on issuance of short term
notes which matured in a subsequent fiscal year to finance its ongoing deficit,
and pay current obligations.  For a two-month period in the summer of 1992,
pending adoption of the annual Budget Act, the State was forced to issue
registered warrants (IOUs) to some of its suppliers, employees and other
creditors.  The last of these deficit notes was repaid in April, 1996.

          The 1995-96 and 1996-97 Budget Acts reflected significantly improved
financial conditions, as the State's economy recovered and tax revenues soared
above projections.  Over the two years, revenues averaged about $2 billion
higher than initially estimated.  Most of the additional revenues were allocated
to school funding, as required by Proposition 98, and to make up shortfalls in
federal aid for health and welfare costs and costs of illegal aliens.  The
budgets for both these years showed strong increases in funding for K-14 public
education, including implementation of initiatives to reduce class sizes for
lower elementary grades to not more than 

                                     -18-
<PAGE>
 
20 pupils. Higher education funding also increased. Spending for health and
welfare programs was kept in check, as previously-implemented cuts in benefit
levels were retained.

          The final results for FY 1996-97 showed General Fund revenues of $49.2
billion and expenditures of $48.9 billion.  The improved revenues allowed the
repayment of the last of the recession-induced budget deficits; the SFEU had a
balance of $408 million on a budgetary basis ($281 million on a cash basis) as
of June 30, 1997, the first significant positive balance in the decade.  In
1996-97, the State implemented its regular cash flow borrowing program with the
issuance of $3.0 billion of Revenue Anticipation Notes which matured on June 30,
1997, and did not require any external borrowing over the end of the fiscal
year.

          Fiscal Year 1997-98 Budget.  With continued strong economic recovery
and surging tax receipts, the State entered the 1997-98 Fiscal Year in the
strongest financial position in the decade.  However, in May 1997, the
California Supreme Court ruled that the State had acted illegally in 1993 and
1994 by using a deferral of payments to the Public Employees Retirement Fund to
help balance earlier budgets.  In response to this court decision, the Governor
ordered an immediate repayment to the Retirement Fund of about $1.235 billion,
which was made in late July, 1997, and substantially "used up" the expected
additional revenues for the fiscal year.

          On August 18, 1997, the Governor signed the 1997-98 Budget Act.  The
Budget Act assumes General Fund revenues and transfers of $52.5 billion, and
contains expenditures of $52.8 billion.  As a result, the budget reserve (SFEU)
is reduced to an estimated $112 million at June 30, 1998.  The Budget Act also
contains $14.4 billion of Special Fund expenditures.  Following enactment of the
Budget Act, the State plans to carry out its normal annual cash flow borrowing,
totaling $3.0 billion to mature June 30, 1998.

          The 1997-98 Budget Act provides another year of rapidly increasing
funding for K-14 public education.  Total General Fund support will reach $5,150
per pupil, more than 20% higher than the recession-period levels which were in
effect as late as FY 1993-94.  The $1.75 billion in new funding will be spent on
class size reduction and other initiatives, as well as fully funding growth and
cost of living increases.  Support for higher education units in the State also
increased by about 6 percent.  Because of the pension payment, most other State
programs were funded at levels consistent with prior years, and several
initiatives had to be dropped.  These included additional assistance to local
governments, state employee raises, and funding of a bond bank.

          Part of the 1997-98 Budget Act was completion of State welfare reform
legislation to implement the new federal law passed in 1996.  The new State
program, called "CalWORKs," to become effective January 1, 1998, will emphasize
programs to bring aid recipients into the workforce.  As required by federal
law, new time limits will be placed on receipt of welfare aid.  Grant levels for
1997-98 remain at the reduced, prior years' levels.

          Although, as noted, the 1997-98 Budget Act projects a budget reserve
in the SFEU of $112 million on June 30, 1998, the General Fund fund balance on
that date also reflects $1.25 billion of "Loans" which the General Fund made to
local schools in the recession years, representing cash outlays above the
mandatory minimum funding level.  Settlement of litigation over these
transactions in July 1996 calls for repayment of these loans over the period
ending in 

                                     -19-
<PAGE>
 
2001-02, about equally split between outlays from the General Fund and from
schools' entitlements. The 1997-98 Budget Act contained a $200 million
appropriation from the General Fund toward this settlement.

          Updated figures from the Department of Finance, released in early
January, 1998, project both revenues and expenditures will be higher in 1997-98
than estimated when the Budget Act was passed, reflecting continued strong
economic activity.  The Department projects the budget reserve (SFEU) at June
30, 1998 will be approximately $329 million.

Proposed 1998-99 Fiscal Year Budget

          The Governor released his proposed FY 1998-99 Budget on January 9,
1998.  It projected General Fund revenues and transfers of $55.4 billion, an
increase of almost 5% over 1997-98.  Revenue losses due to tax cuts enacted in
late 1997 were expected to be offset by higher capital gains realizations.  The
Governor proposed expenditures of $55.4 billion, also an almost 5% increase from
the prior year.  The Governor's Budget proposes significant additional funding
for K-12 schools under Proposition 98, as well as additional funding for higher
education, with a proposed reduction of college student fees.  State and federal
funds will be used in the new CalWORKS welfare program, with projections of a
fourth consecutive year of caseload decline.  The Governor has proposed a large
capital expenditure program, focusing on schools and universities, but also
including corrections, environmental and general government projects.  These
proposals would require approval of almost $10 billion of new general obligation
bonds over the next six years.  All of the Governor's proposals will be reviewed
by the Legislature as part of the annual budget process.

          Although the State's strong economy is producing record revenues to
the State government, the State's budget continues to be under stress from
mandated spending on education, a rising prison population, and social needs of
a growing population with many immigrants.  These factors which limit State
spending growth also put pressure on local governments.  There can be no
assurances that, if economic conditions weaken, or other factors intercede, the
State will not experience budget gaps in the future.

          Bond Ratings.  The ratings on California's long-term general
          ------------                                                
obligation bonds were reduced in the early 1990's from "AAA" levels which had
existed prior to the recession, but have been raised since 1996.  The State's
bonds are currently assigned ratings of "A+" from Standard & Poor's, "A1" from
Moody's and "AA-" from Fitch. There can be no assurance that such ratings will
be maintained in the future. It should be noted that the creditworthiness of
obligations issued by local California issuers may be unrelated to the
creditworthiness of obligations issued by the State of California, and that
there is no obligation on the part of California to make payment on such
obligations in the event of default.

          Legal Proceedings.  California is involved in certain legal
          -----------------                                          
proceedings (described in California's recent financial statements) that, if
decided against California, may require California to make significant future
expenditures or may substantially impair revenues.  Courts have recently entered
decisions which could overturn several parts of the state's recent budget
compromises. The matters covered by these lawsuits include reductions in welfare
payments and 

                                     -20-
<PAGE>
 
the use of certain cigarette tax funds for health costs. All of these cases are
subject to further proceedings and appeals, and if California eventually loses,
the final remedies may not have to be implemented in one year.


          Obligations of Other Issuers
          ---------------------------- 

          Other Issuers of California Instruments.  There are a number of state
          ---------------------------------------                              
agencies, instrumentalities and political subdivisions of the State of
California that issue municipal obligations, some of which may be conduit
revenue obligations payable from payments from private borrowers.  These
entities are subject to various economic risks and uncertainties, and the credit
quality of the securities issued by them may vary considerably from the credit
quality of obligations backed by the full faith and credit of the State of
California.

          State Assistance.  Property tax revenues received by local governments
          ----------------                                                      
declined more than 50% following passage of Proposition 13.  Subsequently, the
California Legislature enacted measures to provide for the redistribution of
California's General Fund surplus to local agencies, the reallocation of certain
state revenues to local agencies and the assumption of certain governmental
functions by the State of California to assist municipal issuers to raise
revenues.  Through 1990-91, local assistance (including public schools)
accounted for around 75% of General Fund spending.  To reduce California General
Fund support for school districts, the 1992-93 and 1993-94 Budget Acts caused
local governments to transfer a total of $3.9 billion of property tax revenues
to school districts, representing loss of all the post-Proposition 13 "bailout"
aid.  The largest share of these transfers came from counties, and the balance
from cities, special districts and redevelopment agencies.  In order to make up
part of this shortfall, the Legislature proposed, and voters approved in 1993,
dedicating 0.5% of the sales tax to counties and cities for public safety
purposes.  In addition, the Legislature has changed laws to relieve local
governments of certain mandates, allowing them to reduce costs.

          Legislation enacted in late 1997 provides for the State to take over
financial responsibility for funding trial courts throughout the State.  This is
estimated to save counties and cities a total of over $350 million annually.

          To the extent that California should be constrained by its Article
XIIIB appropriations limit, or its obligation to conform to Proposition 98, or
other fiscal considerations, the absolute level, or the rate of growth, of state
assistance to local governments may continue to be reduced. Any such reductions
in state aid could compound the serious fiscal constraints already experienced
by many local governments, particularly counties. A number of counties have
indicated that their budgetary condition is extremely serious.  In the 1995-96
and 1996-97 fiscal years, Los Angeles County, the largest in the State, had to
make significant cuts in services and personnel, particularly in the health care
system in order to balance its budget. The County's debt was downgraded by
Moody's and S&P in the summer of 1995. Orange County, which recently emerged
from federal bankruptcy protection, has substantially reduced services and
personnel in order to live within much reduced means.

          Counties and cities may face further budgetary pressures as a result
of changes in welfare and public assistance programs, which were enacted in
August, 1997 in order to comply with the 

                                     -21-
<PAGE>
 
federal welfare reform law. Generally, counties play a large role in the new
system, and are given substantial flexibility to develop and administer programs
to bring aid recipients into the workforce. Counties are also given financial
incentives if either at the county or statewide level, the "Welfare-to-Work"
programs exceed minimum targets; counties are also subject to financial
penalties for failure to meet such targets. Counties remain responsible to
provide "general assistance" for able-bodied indigents who are ineligible for
other welfare programs. The long-term financial impact of the new CalWORKs
system on local governments is still unknown.

          Assessment Bonds.  California Instruments which are assessment bonds
          ----------------                                                    
may be adversely affected by a general decline in real estate values or a
slowdown in real estate sales activity.  In many cases, such bonds are secured
by land which is undeveloped  at the time of issuance but anticipated to be
developed within a few years after issuance.  In the event of such reduction or
slowdown, such development may not occur or may be delayed, thereby increasing
the risk of a default on the bonds.  Because the special assessments or taxes
securing these bonds are not the personal liability of the owners of the
property assessed, the lien on the property is the only security for the bonds.
Moreover, in most cases the issuer of these bonds is not required to make
payments on the bonds in the event of delinquency in the payment of assessments
or taxes, except from amounts, if any, in a reserve fund established for the
bonds.

          California Long-Term Lease Obligations.  Certain California long-term
          --------------------------------------                               
lease obligations, though typically payable from the general fund of the
municipality, are subject to "abatement" in the event the facility being leased
is unavailable for beneficial use and occupancy by the municipality during the
term of the lease. Abatement is not a default, and there may be no remedies
available to the holders of the certificates evidencing the lease obligation in
the event abatement occurs.  The most common cases of abatement are failure to
complete construction of the facility before the end of the period during which
lease payments have been capitalized and uninsured casualty losses to the
facility (e.g. due to earthquake). In the event abatement occurs with respect to
a lease obligation, lease payments may be interrupted (if all available
insurance proceeds and reserves are exhausted) and the certificates may not be
paid when due.

          Several years ago the Richmond Unified School District (the
"District") entered into a lease transaction in which certain existing
properties of the District were sold and leased back in order to obtain funds to
cover operating deficits.  Following a fiscal crisis in which the District's
finances were taken over by a state receiver (including a brief period under
bankruptcy court protection), the District failed to make rental payments on
this lease, resulting in a lawsuit by the Trustee for the Certificate of
Participation holders, in which the State of California was a named defendant
(on the grounds that it controlled the District's finances).  One of the
defenses raised in answer to this lawsuit was the invalidity of the District's
lease.  The trial court upheld the validity of the lease, and the case was
subsequently settled. Any ultimate judgment in any future case against the
position taken by the Trustee may have adverse implications for lease
transactions of a similar nature by other California entities.


          Other Considerations
          --------------------


          The repayment of industrial development securities secured by real
property may be affected by California laws limiting foreclosure rights of
creditors.  Securities backed by health 

                                     -22-
<PAGE>
 
care and hospital revenues may be affected by changes in state regulations
governing cost reimbursements to health care providers under Medi-Cal (the
State's Medicaid program), including risks related to the policy of awarding
exclusive contracts to certain hospitals.

          Limitations on ad valorem property taxes may particularly affect "tax
allocation" bonds issued by California redevelopment agencies.  Such bonds are
secured solely by the increase in assessed valuation of a redevelopment project
area after the start of redevelopment activity.  In the event that assessed
values in the redevelopment project decline (e.g. because of major natural
disaster such as an earthquake), the tax increment revenue may be insufficient
to make principal and interest payments on these bonds.  Both Moody's and S&P
suspended ratings on California tax allocation bonds after the enactment of
Articles XIIIA and XIIIB, and only resumed such ratings on a selective basis.

          Proposition 87, approved by California voters in 1988, requires that
all revenues produced by a tax rate increase go directly to the taxing entity
which increased such tax rate to repay that entity's general obligation
indebtedness.  As a result, redevelopment agencies (which typically are the
issuers of tax allocation securities) no longer receive an increase in tax
increment when taxes on property in the project area are increased to repay
voter-approved bonded indebtedness.

          The effect of these various constitutional and statutory changes upon
the ability of California municipal securities issuers to pay interest and
principal on their obligations remains unclear. Furthermore, other measures
affecting the taxing or spending authority of California or its political
subdivisions may be approved or enacted in the future.  Legislation has been or
may be introduced which would modify existing taxes or other revenue raising
measures or which either would further limit or, alternatively, would increase
the abilities of state and local governments to impose new taxes or increase
existing taxes.  It is not presently possible to predict the extent to which any
such legislation will be enacted.  Nor is it presently possible to determine the
impact of any such legislation on California Instruments in which the California
Portfolio may invest, future allocations of state revenues to local governments
or the abilities of state or local governments to pay the interest on, or repay
the principal of, such California Instruments.

          Substantially all of California is within an active geologic region
subject to major seismic activity.  Northern California in 1989 and Southern
California in 1994 experienced major earthquakes causing billions of dollars in
damages.  The federal government provided more than $13 billion in aid for both
earthquakes, and neither event is expected to have any long-term negative
economic impact.  Any security in the ILA Tax-Exempt California Portfolio could
be affected by an interruption of revenues because of damaged facilities, or,
consequently, income tax deductions for casualty losses or property tax
assessment reductions. Compensatory financial assistance could be constrained by
the inability of (i) an issuer to have obtained earthquake insurance coverage at
reasonable rates; (ii) an insurer to perform on its contracts of insurance in
the event of widespread losses; or (iii) the federal or state government to
appropriate sufficient funds within their respective budget limitations.

Investing in New York


          Some of the significant financial considerations relating to the ILA
Tax-Exempt New York Portfolio's investments in New York Instruments are
summarized below.  This summary information is not intended to be a complete
description and is principally derived from official statements relating to
issues of New York Instruments that were available prior to the date of this
Statement of Additional Information.  The accuracy and completeness of the
information contained in those official statements have not been independently
verified.

          State Economy.  New York is the third most populous state in the
          -------------                                                   
nation and has a relatively high level of personal wealth.  The State's economy
is diverse with a comparatively large share of the nation's finance, insurance,
transportation, communications and services employment, and a very small share
of the nation's farming and mining activity.  The State has a declining
proportion of its workforce engaged in manufacturing, and an increasing
proportion engaged in service industries.  New York City (the "City"), which is
the most populous city in the State and nation and is the center of the nation's
largest metropolitan area, accounts for a large portion of the State's
population and personal income.

          The State has historically been one of the wealthiest states in the
nation.  For decades, however, the State has grown more slowly than the nation
as a whole, gradually eroding its relative economic position.  State per capita
personal income has historically been significantly higher than the national
average, although the ratio has varied substantially.

          Moderate growth is projected to continue in 1998 and 1999 for
employment, wages, and personal income, although the growth rates will lessen
gradually during the course of the two years.  Overall employment growth is
expected to continue at a modest rate, reflecting the slowing growth in the
national economy, continued spending restraint in government, and restructuring
in the health care, social service, and banking sectors.

          There can be no assurance that the State economy will not experience
worse-than-predicted results in the 1996-97 fiscal year, with corresponding
material and adverse effects on the State's projections of receipts and
disbursements.

State Budget.  The State Constitution requires the governor (the "Governor") to
- ------------                                                                   
submit to the State legislature (the "Legislature") a balanced executive budget
which contains a complete plan of expenditures for the ensuing fiscal year and
all moneys and revenues estimated to be available therefor, accompanied by bills
containing all proposed appropriations or reappropriations and any new or
modified revenue measures to be enacted in connection with the executive budget.
The entire plan constitutes the proposed State financial plan for that fiscal
year.  The Governor is required to submit to the Legislature quarterly budget
updates which include a revised cash-basis state financial plan, and an
explanation of any changes from the previous state financial plan.

          The State's budget for the 1996-97 fiscal year was adopted by the
Legislature on August 4, 1997, more than four months after the start of the
fiscal year.  Prior to adoption of the budget, the Legislature enacted
appropriations for disbursements considered to be necessary for State operations
and other purposes, including necessary appropriations for all State-supported
debt 

                                     -24-
<PAGE>
 
service. The State Financial Plan for the 1997-98 fiscal year was formulated on
August 11, 1997 and was based on the State's budget as enacted by the
Legislature, as well as actual results for the first quarter of the current
fiscal year (the "1997-98 State Financial Plan"). In recent years, the State has
failed to adopt a budget prior to the beginning of its fiscal year. There can be
no assurance that State budgets in future fiscal years will be adopted by the
April 1 statutory deadline.

          The Governor is required by law to propose a balanced budget each
year.  In order to address any potential remaining budget gap, the Governor is
expected to make additional proposals to bring receipts in line with
disbursements.  The State has closed projected budget gaps of $5.0 billion, $3.9
billion and $2.3 billion in its 1995-96, 1996-97 and 1997-98 fiscal years,
respectively.

          The 1997-98 General Fund Financial Plan is projected to be balanced on
a cash basis, with a projected cash surplus of $1.83 billion.  As compared to
the Governor's Executive Budget as amended in February 1997, the State's adopted
budget for 1997-98 increased General Fund spending by $1.7 billion, primarily
from increases for local assistance ($1.3 billion).  Resources used to fund
these additional expenditures include increased revenues projected for the 1997-
98 fiscal year, increased resources produced in the 1996-97 fiscal year that
will be utilized in 1997-98, re-estimates of social service, fringe benefit and
other spending, and certain non-recurring resources.

          The 1997-98 adopted budget includes multi-year reductions, including a
State funded property and local income tax reduction program, estate tax relief,
utility gross receipts tax reductions, permanent reductions in the State sales
tax on clothing, and elimination of assessments on medical providers.  These
reductions are intended to reduce the overall level of State and local taxes in
New York and to improve the State's competitive position vis-a-vis other states.
The various elements of the State and local tax and assessments reductions have
little or no impact on the 1997-98 State Financial Plan, and do not begin to
materially affect the outyear projections until the State's 1999-2000 fiscal
year.

          Other actions taken in the 1997-98 adopted budget add further pressure
to future budget balance in New York State.  For example, the fiscal effects of
tax reductions adopted in the 1997-98 budget are projected to grow more
substantially beyond the 1998-99 fiscal year, with incremental costs averaging
in excess of $1.3 billion annually over the last three years of the tax
reduction program.  These incremental costs reflect the phase-in of State-funded
school property tax and local income tax relief, the phase-out of the
assessments on medical providers, and reductions in estate and gift levies,
utility gross receipts taxes, and the State sales tax on clothing.  The full
annual cost of the enacted tax reduction package is estimated at approximately
$4.8 billion when fully effective in State fiscal year 2001-02.  In addition,
the 1997-98 budget included multi-year commitments for school aid and pre-
kindergarten early learning programs which could add as much as $1.4 billion in
costs when fully annualized in fiscal year 2001-02.  These spending commitments
are subject to annual appropriation.

          On September 11, 1997, the New York State Comptroller issued a report
which noted that the ability to deal with future budget gaps could become a
significant issue in the State's 


                                     -25-
<PAGE>
 
2000-2001 fiscal year, when the cost of tax cuts increases by $1.9 billion. The
report contained projections that, based on current economic conditions and
current law for taxes and spending, showed a gap in the 2000-2001 State fiscal
year of $5.6 billion and of $7.4 billion in the 2001-2002 State fiscal year. The
report noted that these gaps would be smaller if recurring spending reductions
produce savings in earlier years. The State Comptroller has also stated that if
Wall Street earnings moderate and the State experiences a moderate recession,
the gap for the 2001-2002 State fiscal year could grow to nearly $12 billion.

          The Governor presented his 1998-99 Executive Budget to the Legislature
on January 20, 1998.  The Executive Budget contains financial projections for
the State's 1997-98 through 2000-01 fiscal years, detailed estimates of receipts
and a proposed Capital Program and Financing Plan for the 1997-98 through 2002-
03 fiscal years.  It is expected that the Governor will prepare amendments to
his Executive Budget as permitted under law and that these amendments will be
reflected in a revised Financial Plan.  There can be no assurance that the
Legislature will enact into law the Executive Budget as proposed by the
Governor, or that the State's adopted budget projections will not differ
materially and adversely from the projections set forth therein.

          The 1998-99 Financial Plan is projected to be balanced on a cash basis
in the General Fund.  Total General Fund receipts, including transfers from
other funds, are projected to be $36.22 billion, an increase of $1.02 billion
over projected receipts in the current fiscal year.  Total General Fund
disbursements, including transfers to other funds, are projected to be $36.18
billion, an increase of $1.02 billion over the projected expenditures (including
pre-payments), for the current fiscal year.  As compared to the 1997-98 State
Financial Plan, the Executive Budget proposes year-to-year growth in General
Fund spending of 2.89 percent.  State Funds spending (i.e., General Fund plus
other dedicated funds, with the exception of federal aid) is projected to grow
by 8.5 percent.  Spending from all Governmental Funds (excluding transfers) is
proposed to increase by 7.6 percent from the prior fiscal year.

          The forecast of General Fund receipts in 1998-99 incorporates several
Executive Budget tax proposals that, if enacted, would further reduce receipts
otherwise available to the General Fund by approximately $700 million during
1998-99.  The Executive Budget proposes accelerating school tax relief for
senior citizens under STAR, which is projected to reduce General Fund receipts
by $537 million in 1998-99.  The proposed reduction supplements STAR tax
reductions already scheduled in law, which are projected at $187 million in
1998-99.  The Budget also proposes several new tax-cut initiatives and other
funding changes that are projected to further reduce receipts available to the
General Fund by over $200 million.  These initiatives include reducing the fee
to register passenger motor vehicles and earmarking a larger portion of such
fees to dedicated funds and other purposes; extending the number of weeks in
which certain clothing purchases are exempt from sales taxes; more fully
conforming State law to reflect recent Federal changes in estate taxes;
continuing lower pari-mutuel tax rates; and accelerating scheduled property tax
relief for farmers from 1999 to 1998.  In addition to the specific tax and fee
reductions discussed above, the Executive Budget also proposes establishing a
reserve of $100 million to permit the acceleration into 1998-99 of other tax
reductions that are otherwise scheduled in law for implementation in future
fiscal years.


                                     -26-
<PAGE>
 
          The Division of the Budget estimates that the 1998-99 Financial Plan
includes approximately $62 million in non-recurring resources, comprising less
than two-tenths of one percent of General Fund disbursements.  The non-recurring
resources projected for use in 1998-99 consist of $27 million in retroactive
federal welfare reimbursements for family assistance recipients with HIV/AIDS,
$25 million in receipts from the Housing Finance Agency that were originally
anticipated in 1997-98, and $10 million in other measures, including $5 million
in asset sales.

          Disbursements from Capital Projects funds in 1998-99 are estimated at
$4.82 billion, or $1.07 billion higher than 1997-98.  The proposed spending plan
includes:  $2.51 billion in disbursements for transportation purposes, including
the State and local highway and bridge program; $815 million for environmental
activities; $379 million for correctional services; $228 million for the State
University of New York ("SUNY") and the City University of New York ("CUNY");
$290 million for mental hygiene projects; and $375 million for CEFAP.
Approximately 28 percent of capital projects are proposed to be financed by
"pay-as-you-go" resources.  State-supported bond issuances finance 46 percent of
capital projects, with federal grants financing the remaining 26 percent.

          The economic and financial condition of the State may be affected by
various financial, social, economic and political factors.  Those factors can be
very complex, may vary from fiscal year to fiscal year, and are frequently the
result of actions taken not only by the State and its agencies and
instrumentalities, but also by entities, such as the federal government, that
are not under the control of the State.  In addition, the financial plan is
based upon forecasts of national and State economic activity.  Economic
forecasts have frequently failed to predict accurately the timing and magnitude
of changes in the national and the State economies.  Actual results, however,
could differ materially and adversely from the projections set forth in a
financial plan, and those projections may be changed materially and adversely
from time to time.

          In the past, the State has taken management actions and made use of
internal sources to address potential State financial plan shortfalls, and the
Division of Budget believes it could take similar actions should variances occur
in its projections for the current fiscal year.

Recent Financial Results.  The General Fund is the principal operating fund of
- ------------------------                                                      
the State and is used to account for all financial transactions, except those
required to be accounted for in another fund.  It is the State's largest fund
and receives almost all State taxes and other resources not dedicated to
particular purposes.

          The State ended the first six months of its 1997-98 fiscal year with
an unaudited General Fund cash balance of $3.2 billion, or $254 million above
the August Financial Plan estimate.  Total unaudited receipts, including
transfers from other funds, totaled $18.8 billion, or $340 million higher than
expected.  The additional receipts reflected higher-than-anticipated tax
revenues of $244 million and miscellaneous receipts of $93 million.  Unaudited
General Fund spending for the same period equaled $16.0 billion, or $86 million
above the cashflow projections published in the August Financial Plan.  For
fiscal year 1997-98, total General Fund receipts were projected at $35.09
billion, an increase of $2.05 billion from 1996-97 results.  Total

                                     -27-
<PAGE>
 
disbursements, including transfers to capital projects, debt service and other
funds, were projected at $34.60 billion, or 5.2 percent higher than
disbursements in 1996-97.

          The mid-year update projected a closing balance in the General Fund of
$927 million, which was composed of a $530 million reserve for future needs, a
$332 million balance in the Tax Stabilization Reserve Fund ("TSRF"), and a $65
million balance in the Contingency Reserve Fund ("CRF").

          As part of the 1997-98 Adopted Budget Report, the State also issued
its update to the GAAP-basis Financial Plan for the State's 1997-98 fiscal year,
based on the cash-basis 1997-98 State Financial Plan completed in August.  The
GAAP-basis update projected a General Fund operating deficit of $959 million,
primarily reflecting the use of a portion of the 1996-97 cash surplus to fund
1997-98 liabilities, offset by the $530 million reserve for future needs.

Debt Limits and Outstanding Debt.  There are a number of methods by which the
- --------------------------------                                             
State of New York may incur debt.  Under the State Constitution, the State may
not, with limited exceptions for emergencies, undertake long-term general
obligation borrowing (i.e., borrowing for more than one year) unless the
                      ----                                              
borrowing is authorized in a specific amount for a single work or purpose by the
Legislature and approved by the voters.  There is no limitation on the amount of
long-term general obligation debt that may be so authorized and subsequently
incurred by the State.

          The State may undertake short-term borrowings without voter approval
(i) in anticipation of the receipt of taxes and revenues, by issuing tax and
revenue anticipation notes, and (ii) in anticipation of the receipt of proceeds
from the sale of duly authorized but unissued general obligation bonds, by
issuing bond anticipation notes.  The State may also, pursuant to specific
constitutional authorization, directly guarantee certain obligations of the
State of New York's authorities and public benefit corporations ("Authorities").
Payments of debt service on New York State general obligation and New York
State-guaranteed bonds and notes are legally enforceable obligations of the
State of New York.

          The State employs additional long-term financing mechanisms, lease-
purchase and contractual-obligation financings, which involve obligations of
public authorities or municipalities that are State-supported but are not
general obligations of the State.  Under these financing arrangements, certain
public authorities and municipalities have issued obligations to finance the
construction and rehabilitation of facilities or the acquisition and
rehabilitation of equipment, and expect to meet their debt service requirements
through the receipt of rental or other contractual payments made by the State.
Although these financing arrangements involve a contractual agreement by the
State to make payments to a public authority, municipality or other entity, the
State's obligation to make such payments is generally expressly made subject to
appropriation by the Legislature and the actual availability of money to the
State for making the payments.  The State has also entered into a contractual-
obligation financing arrangement with the Local Government Assistance
Corporation ("LGAC") to restructure the way the State makes certain local aid
payments.

          In February 1997, the Job Development Authority ("JDA") issued
approximately $85 million of State-guaranteed bonds to refinance certain of its
outstanding bonds and notes in order 

                                     -28-
<PAGE>
 
to restructure and improve JDA's capital structure. Due to concerns regarding
the economic viability of its programs, JDA's loan and loan guarantee activities
had been suspended since the Governor took office in 1995. As a result of the
structural imbalances in JDA's capital structure, and defaults in its loan
portfolio and loan guarantee program incurred between 1991 and 1996, JDA would
have experienced a debt service cash flow shortfall had it not completed its
recent refinancing. JDA anticipates that it will transact additional
refinancings in 1999, 2000 and 2003 to complete its long-term plan of finance
and further alleviate cash flow imbalances which are likely to occur in future
years. The State does not anticipate that it will be called upon to make any
payments pursuant to the State guarantee in the 1997-98 fiscal year. JDA
recently resumed its lending activities under a revised set of lending programs
and underwriting guidelines.

          In 1990, as part of a State fiscal reform program, legislation was
enacted creating LGAC, a public benefit corporation empowered to issue long-term
obligations to fund certain payments to local governments traditionally funded
through New York State's annual seasonal borrowing.  The legislation empowered
LGAC to issue its bonds and notes in an amount to yield net proceeds not in
excess of $4.7 billion (exclusive of certain refunding bonds).  Over a period of
years, the issuance of these long-term obligations, which are to be amortized
over no more than 30 years, was expected to eliminate the need for continued
short-term seasonal borrowing. The legislation also dedicated revenues equal to
one-quarter of the four cent State sales and use tax to pay debt service on
these bonds.  The legislation also imposed a cap on the annual seasonal
borrowing of the State at $4.7 billion, less net proceeds of bonds issued by
LGAC and bonds issued to provide for capitalized interest, except in cases where
the Governor and the legislative leaders have certified the need for additional
borrowing and provided a schedule for reducing it to the cap.  If borrowing
above the cap was thus permitted in any fiscal year it was required by law to be
reduced to the cap by the fourth fiscal year after the limit was first exceeded.
As of June 1995, LGAC had issued bonds to provide net proceeds of $4.7 billion,
completing the program.

          On January 13, 1992, S&P reduced its ratings on the State's general
obligation bonds from A to A- and, in addition, reduced its ratings on the
State's moral obligation, lease purchase, guaranteed and contractual obligation
debt.  On August 28, 1997, S&P revised its ratings on the State's general
obligation bonds from A- to A and revised its ratings on the State's moral
obligation, lease purchase, guaranteed and contractual obligation debt.  On
March 2, 1998, S&P affirmed its A rating on the State's outstanding bonds.

          On January 6, 1992, Moody's reduced its ratings on outstanding
limited-liability State lease purchase and contractual obligations from A to
Baa1.  On February 28, 1994, Moody's reconfirmed its A rating on the State's
general obligation long-term indebtedness.  On March 20, 1998, Moody's assigned
the highest commercial paper rating of P-1 to the short-term notes of the State
and stated that the outlook for the State's general obligations is stable.

          The State anticipated that its capital programs will be financed, in
part, by State and public authorities borrowings in the 1997-98 fiscal year.
The State expects to issue $605 million in general obligation bonds (including
$140 million for purposes of redeeming outstanding bond anticipation notes) and
$140 million in general obligation commercial paper.  The Legislature had also
authorized the issuance of $311 million in certificates of participation
(including costs of issuance, reserve funds and other costs) during the State's
1997-98 fiscal year for equipment 

                                     -29-
<PAGE>
 
purchases. The projection of State borrowings for the 1997-98 fiscal year is
subject to change as market conditions, interest rates and other factors vary
throughout the fiscal year.

          The proposed 1997-98 through 2002-03 Capital Program and Financing
Plan was released with the 1998-99 Executive Budget on January 20, 1998. As a
part of that Plan, changes were proposed to the State's 1997-98 borrowing plan,
including: the delay in the issuance of COPs to finance welfare information
systems until 1998-99 to permit a thorough assessment of needs; and the
elimination of issuances for the CEFAP to reflect the proposed conversion of
that bond-financed program to pay-as-you-go financing.

          As a result of these changes, the State's 1997-98 borrowing plan now
reflects: $501 million in general obligation bonds (including $140 million for
purposes of redeeming outstanding BANs) and $140 million in general obligation
commercial paper; the issuance of $83 million in COPs for equipment purchases;
and approximately $1.8 billion in borrowings by public authorities pursuant to
lease-purchase and contractual-obligation financings for capital programs of the
State, including costs of issuance, reserve funds, and other costs, net of
anticipated refundings and other adjustments for 1997-98 capital projects.  The
projection of State borrowings for the 1997-98 fiscal year is subject to change
as market conditions, interest rates and other factors vary through the end of
the fiscal year.

          New York State has never defaulted on any of its general obligation
indebtedness or its obligations under lease-purchase or contractual-obligation
financing arrangements and has never been called upon to make any direct

Litigation.  Certain litigation pending against the State or its officers or

employees could have a substantial or long-term adverse effect on State
finances.  Among the more significant of these cases are those that involve (1)
the validity of agreements and treaties by which various Indian tribes
transferred title to New York State of certain land in central and upstate New
York; (2) certain aspects of New York State's Medicaid policies, including its
rates, regulations and procedures; (3) action against New York State and New
York City officials alleging inadequate shelter allowances to maintain proper
housing; (4) challenges to the practice of reimbursing certain Office of Mental
Health patient care expenses from the client's Social Security benefits; (5)
alleged responsibility of New York State officials to assist in remedying racial
segregation in the City of Yonkers; (6) challenges to regulations promulgated by
the Superintendent of Insurance establishing certain excess medical malpractice
premium rates; (7) challenges to certain aspects of petroleum business taxes;
(8) action alleging damages resulting from the failure by the State's Department
of Environmental Conservation to timely provide certain data; (9) challenges to
the constitutionality of Public Health Law 2807-d, which imposes a gross
receipts tax from certain patient care services; (10) an action seeking
reimbursement from the State for certain costs arising out of the provision of
pre-school services and programs for children with handicapped conditions; (11)
action seeking enforcement of certain sales and excise taxes and tobacco
products and motor fuel sold to non-Indian consumers on Indian reservations; and
(12) a challenge to the constitutionality of Clean Water/Clean Air Bond Act.

          Several actions challenging the constitutionality of legislation
enacted during the 1990 legislative session which changed actuarial funding
methods for determining state and local 

                                     -30-

contributions to state employee retirement systems have been decided against the
State. As a result, the Comptroller developed a plan to restore the State's
retirement systems to prior funding levels. Such funding is expected to exceed
prior levels by $116 million in fiscal 1996-97, $193 million in fiscal 1997-98,
peaking at $241 million in fiscal 1998-99. Beginning in fiscal 2001-02, State
contributions required under the Comptroller's plan are projected to be less
than that required under the prior funding method. As a result of the United
States Supreme Court decision in the case of State of Delaware v. State of New
                                             -----------------    ------------
York, on January 21, 1994, the State entered into a settlement agreement with
- ----
various parties. Pursuant to all agreements executed in connection with the
action, the State was required to make aggregate payments of $351.4 million.
Annual payments to the various parties will continue through the State's 2002-03
fiscal year in amounts which will not exceed $48.4 million in any fiscal year
subsequent to the State's 1994-95 fiscal year. Litigation challenging the
constitutionality of the treatment of certain moneys held in a reserve fund was
settled in June 1996 and certain amounts in a Supplemental Reserve Fund
previously credited by the State against prior State and local pension
contributions will be paid in 1998.

          The legal proceedings noted above involve State finances, State
programs and miscellaneous cure rights, tort, real property and contract claims
in which the State is a defendant and the monetary damages sought are
substantial, generally in excess of $100 million.  These proceedings could
affect adversely the financial condition of the State in the 1997-98 fiscal year
or thereafter.  Adverse developments in these proceedings, other proceedings for
which there are unanticipated, unfavorable and material judgments, or the
initiation of new proceedings could affect the ability of the State to maintain
a balanced financial plan.  An adverse decision in any of these proceedings
could exceed the amount of the reserve established in the State's financial plan
for the payment of judgments and, therefore, could affect the ability of the
State to maintain a balanced financial plan.  In its audited financial
statements for the 1996-97 fiscal year, the State reported its estimated
liability for awarded and anticipated unfavorable judgments to be $364 million,
of which $134 million is expected to be paid during the 1997-98 fiscal year.

          Although other litigation is pending against New York State, except as
described herein, no current litigation involves New York State's authority, as
a matter of law, to contract indebtedness, issue its obligations, or pay such
indebtedness when it matures, or affects New York State's power or ability, as a
matter of law, to impose or collect significant amounts of taxes and revenues.

Authorities.  The fiscal stability of New York State is related, in part, to the

fiscal stability of its Authorities, which generally have responsibility for
financing, constructing and operating revenue-producing public benefit
facilities.  Authorities are not subject to the constitutional restrictions on
the incurrence of debt which apply to the State itself, and may issue bonds and
notes within the amounts of, and as otherwise restricted by, their legislative
authorization.  The State's access to the public credit markets could be
impaired, and the market price of its outstanding debt may be materially and
adversely affected, if any of the Authorities were to default on their
respective obligations, particularly with respect to debt that is State-
supported or State-related.  There can be no assurance that there will not be
reductions in State aid to the City from amounts currently projected or that
State budgets will be adopted by the April 1 statutory deadline or that any such
reductions or delays will not have adverse effects on the City's cash 

                                     -31-

flow or expenditures. In addition, the Federal budget negotiation process could
result in a reduction in or a delay in the receipt of Federal grants which could
have additional adverse effects on the City's cash flow or revenues.

          Authorities are generally supported by revenues generated by the
projects financed or operated, such as fares, user fees on bridges, highway
tolls and rentals for dormitory rooms and housing. In recent years, however, New
York State has provided financial assistance through appropriations, in some
cases of a recurring nature, to certain of the Authorities for operating and
other expenses and, in fulfillment of its commitments on moral obligation
indebtedness or otherwise, for debt service.  This operating assistance is
expected to continue to be required in future years. In addition, certain
statutory arrangements provide for State local assistance payments otherwise
payable to localities to be made under certain circumstances to certain
Authorities.  The State has no obligation to provide additional assistance to
localities whose local assistance payments have been paid to Authorities under
these arrangements.  However, in the event that such local assistance payments
are so diverted, the affected localities could seek additional State funds.

New York City and Other Localities.  The fiscal health of the State of New York
- ----------------------------------                                             
may also be impacted by the fiscal health of its localities, particularly the
City of New York, which has required and continues to require significant
financial assistance from New York State.  The City depends on State aid both to
enable the City to balance its budget and to meet its cash requirements.  There
can be no assurance that there will not be reductions in State aid to the City
from amounts currently projected or that State budgets will be adopted by the
April 1 statutory deadline or that any such reductions or delays will not have
adverse effects on the City's cash flow or expenditures.  In addition, the
Federal budget negotiation process could result in a reduction in or a delay in
the receipt of Federal grants which could have additional adverse effects on the
City's cash flow or revenues.

          In 1975, New York City suffered a fiscal crisis that impaired the
borrowing ability of both the City and New York State.  In that year the City
lost access to the public credit markets.  The City was not able to sell short-
term notes to the public again until 1979.  In 1975, S&P suspended its A rating
of City bonds.  This suspension remained in effect until March 1981, at which
time the City received an investment grade rating of BBB from S&P.

          On July 2, 1985, S&P revised its rating of City bonds upward to BBB+
and on November 19, 1987, to A-. On February 3, 1998, S&P placed a BBB+ rating
on the City's general obligation debt on CreditWatch with positive implications.
Moody's ratings of City bonds were revised in November 1981 from B (in effect
since 1977) to Ba1, in November 1983 to Baa, in December 1985 to Baa1, in May
1988 to A and again in February 1991 to Baa1.  On February 25, 1998, Moody's
upgraded nearly $28 billion of the City's debt from Baa1 to A3.

          New York City is heavily dependent on New York State and federal
assistance to cover insufficiencies in its revenues.  There can be no assurance
that in the future federal and State assistance will enable the City to make up
its budget deficits.  To help alleviate the City's financial difficulties, the
Legislature created the Municipal Assistance Corporation ("MAC") in 1975.  Since
its creation, MAC has provided, among other things, financing assistance to the
City 

                                     -32-
<PAGE>
 
by refunding maturing City short-term debt and transferring to the City funds
received from sales of MAC bonds and notes. MAC is authorized to issue bonds and
notes payable from certain stock transfer tax revenues, from the City's portion
of the State sales tax derived in the City and, subject to certain prior claims,
from State per capita aid otherwise payable by the State to the City. Failure by
the State to continue the imposition of such taxes, the reduction of the rate of
such taxes to rates less than those in effect on July 2, 1975, failure by the
State to pay such aid revenues and the reduction of such aid revenues below a
specified level are included among the events of default in the resolutions
authorizing MAC's long-term debt. The occurrence of an event of default may
result in the acceleration of the maturity of all or a portion of MAC's debt.
MAC bonds and notes constitute general obligations of MAC and do not constitute
an enforceable obligation or debt of either the State or the City. As of June
30, 1997, MAC had outstanding an aggregate of approximately $4.267 billion of
its bonds. MAC is authorized to issue bonds and notes to refunds its outstanding
bonds and notes and to fund certain reserves, without limitation as to principal
amount, and to finance certain capital commitments to the Transit Authority and
the New York City School Construction Authority for the 1997 fiscal year in the
event the City fails to provide such financing.

          Since 1975, the City's financial condition has been subject to
oversight and review by the New York State Financial Control Board (the "Control
Board") and since 1978 the City's financial statements have been audited by
independent accounting firms.  To be eligible for guarantees and assistance, the
City is required during a "control period" to submit annually for Control Board
approval, and when a control period is not in effect for Control Board review, a
financial plan for the next four fiscal years covering the City and certain
agencies showing balanced budgets determined in accordance with GAAP.  New York
State also established the Office of the State Deputy Comptroller for New York
City ("OSDC") to assist the Control Board in exercising its powers and
responsibilities.  On June 30, 1986, the City satisfied the statutory
requirements for termination of the control period.  This means that the Control
Board's powers of approval are suspended, but the Board continues to have
oversight responsibilities.

          The City since 1981 has fully satisfied its seasonal financing needs
in the public credit markets, repaying all short-term obligations within their
fiscal year of issuance.  Although the City's current financial plan projects
$2.4 billion of seasonal financing for the 1998 fiscal year, the City expects to
undertake only approximately $1.4 billion of seasonal financing.  The City
issued $2.4 billion of short-term obligations in fiscal year 1997.  Seasonal
financing requirements for the 1996 fiscal year increased to $2.4 billion from
$2.2 billion and $1.75 billion in the 1995 and 1994 fiscal years, respectively.
Seasonal financing requirements were $1.4 billion in the 1993 fiscal year.  The
delay in the adoption of the State's budget in certain past fiscal years has
required the City to issue short-term notes in amounts exceeding those expected
early in such fiscal years.

          Certain localities, in addition to the City, have experienced
financial problems and have requested and received additional New York State
assistance during the last several State fiscal years.  The potential impact on
the State of any future requests by localities for additional assistance is not
included in the State's projections of its receipts and disbursements for the
1997-98 fiscal year.


                                     -33-

          Fiscal difficulties experienced by the City of Yonkers ("Yonkers")
resulted in the re-establishment of the Financial Control Board for the City of
Yonkers (the "Yonkers Board") by New York State in 1984. The Yonkers Board is
charged with oversight of the fiscal affairs of Yonkers.  Future actions taken
by the State to assist Yonkers could result in increased State expenditures for
extraordinary local assistance.

          Beginning in 1990, the City of Troy experienced a series of budgetary
deficits that resulted in the establishment of a Supervisory Board for the City
of Troy in 1994.  The Supervisory Board's powers were increased in 1995, when
Troy MAC was created to help Troy avoid default on certain obligations.  The
legislation creating Troy MAC prohibits the city of Troy from seeking federal
bankruptcy protection while Troy MAC bonds are outstanding.  Troy MAC has issued
bonds to effect a restructuring of the City of Troy's obligations.

          Eighteen municipalities received extraordinary assistance during the
1996 legislative session through $50 million in special appropriations targeted
for distressed cities, and that was largely continued in 1997.  Twenty-eight
municipalities are scheduled to share in more than $32 million in targeted
unrestricted aid allocated in the 1997-98 budget.  An additional $21 million
will be dispersed among all cities, towns and villages, a 3.97% increase in
General Purpose State Aid.

          Municipalities and school districts have engaged in substantial short-
term and long-term borrowings.  In 1995, the total indebtedness of all
localities in New York State other than New York City was approximately $19
billion.  A small portion (approximately $102.3 million) of that indebtedness
represented borrowing to finance budgetary deficits and was issued pursuant to
enabling New York State legislation.  State law requires the comptroller to
review and make recommendations concerning the budgets of those local government
units other than New York City authorized by State law to issue debt to finance
deficits during the period that such deficit financing is outstanding.  Eighteen
localities had outstanding indebtedness for deficit financing at the close of
their fiscal year ending in 1995.

          From time to time, federal expenditure reductions could reduce, or in
some cases eliminate, federal funding of some local programs and accordingly
might impose substantial increased expenditure requirements on affected
localities.  If New York State, New York City or any of the Authorities were to
suffer serious financial difficulties jeopardizing their respective access to
the public credit markets, the marketability of notes and bonds issued by
localities within New York State could be adversely affected. Localities also
face anticipated and potential problems resulting from certain pending
litigation, judicial decisions and long-range economic trends.  Long-range
potential problems of declining urban population, increasing expenditures and
other economic trends could adversely affect localities and require increasing
New York State assistance in the future.

Standby Commitments

          In order to enhance the liquidity, stability or quality of municipal
obligations, the ILA Prime Obligations Portfolio, ILA Money Market Portfolio,
ILA Tax-Exempt Diversified 


                                     -34-
<PAGE>
 
Portfolio, ILA Tax-Exempt California Portfolio, ILA Tax-Exempt New York
Portfolio, FS Prime Obligations Fund, FS Premium Fund, FS Money Market Fund, FS
Tax-Free Fund and FS Municipal Fund each may acquire the right to sell a
security to another party at a guaranteed price and date. Such a right to resell
may be referred to as a put, demand feature or "standby commitment", depending
on its characteristics. The aggregate price which a Series pays for securities
with standby commitments may be higher than the price which otherwise would be
paid for the securities. Standby commitments may not be available or may not be
available on satisfactory terms.

          Standby commitments may involve letters of credit issued by domestic
or foreign banks supporting the other party's ability to purchase the security
from the Series.  The right to sell may be exercisable on demand or at specified
intervals, and may form part of a security or be acquired separately by the
Series.

          Management of the Trust understands that the Internal Revenue Service
has issued a favorable revenue ruling to the effect that, under specified
circumstances, a registered investment company will be the owner of tax-exempt
municipal obligations acquired subject to a put option.  Institutional Tax-
Exempt Assets, the predecessor company of which ILA Tax-Exempt Diversified
Portfolio and ILA Tax-Exempt California Portfolio were series, has received a
ruling (which does not serve as precedent for other taxpayers and which are
applicable only to the taxpayer requesting the ruling and which have, on
occasion, been reversed by the Internal Revenue Service) from the Internal
Revenue Service to the effect that it is considered the owner of the municipal
obligations subject to standby commitments so that the interest on such
instruments will be tax-exempt income to it.  The Internal Revenue Service has
subsequently announced that it will not ordinarily issue advance ruling letters
as to the identity of the true owner of property in cases involving the sale of
securities or participation interests therein if the purchaser has the right to
cause the security, or the participation interest therein, to be purchased by
either the seller or a third party.  Each of the ILA Tax-Exempt Diversified
Portfolio, ILA Tax-Exempt California Portfolio, ILA Tax-Exempt New York
Portfolio, FS Tax-Free Fund and FS Municipal Fund intends to take the position
that it is the owner of any municipal obligations acquired subject to a standby
commitment or acquired or held with certain other types of put rights and that
its distributions of tax-exempt interest earned with respect to such municipal
obligations will be tax-exempt for its unitholders.  There is no assurance that
standby commitments will be available to a Series nor has any Series assumed
that such commitments will continue to be available under all market conditions.

Non-Diversified Status

          Since the ILA Tax-Exempt California Portfolio and ILA Tax-Exempt New
York Portfolio are "non-diversified" under the 1940 Act, each is subject only to
their requirements.  Under federal tax laws, the ILA Tax-Exempt California
Portfolio and ILA Tax-Exempt New York Portfolio may, with respect to 50% of
their total assets, invest up to 25% of their total assets in the securities of
any issuer (except that this limitation does not apply to U.S. Government
Securities).  With respect to the remaining 50% of each Fund's total assets, (1)
the Fund may not invest more than 5% of its total assets in the securities of
any one issuer (other than the U.S. government), and (2) the Fund may acquire
more than 10% of the outstanding voting securities 

                                     -35-
<PAGE>
 
of any one issuer. These tests apply at the end of each quarter of its taxable
year and are subject to certain conditions and limitations under the Code.


                             INVESTMENT LIMITATIONS

          The following restrictions may not be changed with respect to any
Series without the approval of the majority of outstanding voting securities of
that Series (which, under the Act and the rules thereunder and as used in the
Prospectus and this Statement of Additional Information, means the lesser of (1)
67% of the units of that Series present at a meeting if the holders of more than
50% of the outstanding units of that Series are present in person or by proxy,
or (2) more than 50% of the outstanding units of that Series).  Investment
restrictions that involve a maximum percentage of securities or assets shall not
be considered to be violated unless an excess over the percentage occurs
immediately after, and is caused by, an acquisition or encumbrance of securities
or assets of, or borrowings by or on behalf of, a Series, with the exception of
borrowings permitted by Investment Restriction (3).

          Accordingly, the Trust may not, on behalf of any Series (except for FS
Government Fund):

             (1) Make any investment inconsistent with the Series'
          classification as a diversified company under the Act. This
          restriction does not, however, apply to any Series classified as a 
          non-diversified company under the Act.


             (2) Purchase securities if such purchase would cause more than 25%
          in the aggregate of the market value of the total assets of a Series
          to be invested in the securities of one or more issuers having their
          principal business activities in the same industry, provided that
          there is no limitation with respect to, and each Series (other than
          the FS Money Market Fund and FS Premium Fund) reserves freedom of
          action, when otherwise consistent with its investment policies, to
          concentrate its investments in obligations issued or guaranteed by the
          U.S. Government, its agencies or instrumentalities, obligations (other
          than commercial paper) issued or guaranteed by U.S. banks and U.S.
          branches of U.S. or foreign banks and repurchase agreements and
          securities loans collateralized by such U.S. Government obligations or
          such bank obligations. Each of FS Money Market Fund and FS Premium
          Fund may concentrate its investments in obligations issued or
          guaranteed by the U.S. Government, its agencies and instrumentalities
          and repurchase agreements and securities loans collateralized by such
          obligations and will invest more than 25% of its total assets in
          obligations issued or guaranteed by banks (whether foreign or
          domestic) and repurchase agreements and securities loans
          collateralized by such obligations. However, if adverse economic
          conditions prevail in the banking industry, each of FS Money Market
          Fund and FS Premium Fund may, for defensive purposes, temporarily
          invest less than 25% of the value of its total assets in such
          obligations. Notwithstanding the foregoing, the ILA Money Market
          Portfolio will invest more than 25% of the value of its total assets
          in bank obligations (whether foreign or domestic) except that if
          adverse economic conditions prevail in the banking industry, the ILA
          Money Market Portfolio may, for defensive 


                                     -36-
<PAGE>
 
          purposes, temporarily invest less than 25% of its total assets in bank
          obligations. For the purposes of this restriction, state and municipal
          governments and their agencies, authorities and instrumentalities are
          not deemed to be industries; telephone companies are considered to be
          a separate industry from water, gas or electric utilities; personal
          credit finance companies and business credit finance companies are
          deemed to be separate industries; and wholly owned finance companies
          are considered to be in the industry of their parents if their
          activities are primarily related to financing the activities of their
          parents.

             (3) Borrow money, except that (a) the Series may borrow from banks
          (as defined in the Act) or through reverse repurchase agreements in
          amounts up to 33 1/3% of its total assets (including the amount
          borrowed), (b) the Series may, to the extent permitted by applicable
          law, borrow up to an additional 5% of its total assets for temporary
          purposes, (c) the Series may obtain such short-term credit as may be
          necessary for the clearance of purchases and sales of portfolio
          securities and (d) the Series may purchase securities on margin to the
          extent permitted by applicable law.

             (4) Make loans, except (a) through the purchase of debt obligations
          in accordance with each Series' investment objective and policies, (b)
          through repurchase agreements with banks, brokers, dealers and other
          financial institutions, (c) with respect to the Financial Square
          Funds, loans of securities as permitted by applicable law, and (d)
          with respect to the ILA Portfolios, loans of securities.

             (5) Underwrite securities issued by others, except to the extent
          that the sale of portfolio securities by the Series may be deemed to
          be an underwriting.

             (6) Purchase, hold or deal in real estate, although the Series may
          purchase and sell securities that are secured by real estate or
          interests therein, securities of real estate investment trusts and
          mortgage-related securities and may hold and sell real estate acquired
          by the Series as a result of the ownership of securities.

             (7) Invest in commodities or commodity contracts, except that the
          Series may invest in currency and financial instruments and contracts
          that are commodities or commodity contracts.

             (8) Issue senior securities to the extent such issuance would
          violate applicable law.

          FS Government Fund may not:

             (1) With respect to 75% of its total assets taken at market value,
          invest more than 5% of the value of the total assets of that Series in
          the securities of any one issuer, except U.S. Government securities
          and repurchase agreements collateralized by U.S. Government
          securities. This restriction does not, however, apply to any Series
          classified as a non-diversified company under the Act.


                                     -37-
<PAGE>
 
          (2) With respect to 75% of its total assets taken at market value,
     purchase the securities of any one issuer if, as a result of such purchase,
     that Series would hold more than 10% of the outstanding voting securities
     of that issuer.  This restriction does not, however, apply to any Series
     classified as a non-diversified company under the Act.

          (3) Borrow money, except from banks on a temporary basis for
     extraordinary or emergency purposes, provided that a Series is required to
     maintain asset coverage of 300% for all borrowings and that no purchases of
     securities will be made if such borrowings exceed 5% of the value of the
     Series' assets. This restriction does not apply to cash collateral received
     as a result of portfolio securities lending.

          (4) Mortgage, pledge or hypothecate its assets except to secure
     permitted borrowings.


          (5) Act as underwriter of the securities issued by others, except to
     the extent that the purchase of securities in accordance with a Series'
     investment objective and policies directly from the issuer thereof and the
     later disposition thereof may be deemed to be underwriting.

          (6) Purchase securities if such purchase would cause more than 25% in
     the aggregate of the market value of the total assets of a Series to be
     invested in the securities of one or more issuers having their principal
     business activities in the same industry, provided that there is no
     limitation with respect to, and the Series reserves freedom of action, when
     otherwise consistent with its investment policies to, concentrate its
     investments in, U.S. Government securities, obligations (other than
     commercial paper) issued or guaranteed by U.S. banks, and U.S. branches of
     foreign banks and repurchase agreements and securities loans collateralized
     by U.S. Government securities or such bank obligations. (For the purposes
     of this restriction, state and municipal governments and their agencies and
     authorities are not deemed to be industries, and telephone companies are
     considered to be a separate industry from water, gas or electric utilities,
     personal credit finance companies and business credit finance companies are
     deemed to be separate industries and wholly-owned finance companies are
     considered to be in the industry of their parents if their activities are
     primarily related to financing the activities of their parents. Such
     concentration may be effected when the Adviser determines that risk
     adjusted returns in such industries are considered favorable relative to
     other industries.)

          (7) Issue senior securities, except as appropriate to evidence
     indebtedness that a Series is permitted to incur and except for shares of
     existing or additional series of the Trust.

          (8) Purchase or sell real estate (excluding securities secured by real
     estate or interests therein), interests in oil, gas or mineral leases,
     commodities or commodities contracts.  The Trust reserves the freedom to
     hold and to sell real estate acquired for any Series as a result of the
     ownership of securities.

          (9)  Make loans to other persons, except loans of portfolio securities
     and except to the extent that the purchase of debt obligations and entry
     into repurchase agreements in accordance with such Series' investment
     objective and policies may be deemed to be loans.

          (10) Purchase securities on margin (except for delayed delivery or
     when-issued transactions or such short-term credits as are necessary for
     the clearance of transactions), make short sales of securities, maintain a
     short position, or invest in or write puts, calls or combinations thereof
     (except that a Series may acquire puts in connection with the acquisition
     of a debt instrument).

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

     Each Series may, notwithstanding any other fundamental investment
restriction or policy, invest some or all of its assets in a single open-end
investment company or series thereof with substantially the same investment
objectives, restrictions and policies as the Series.

     As money market funds, the Series must also comply with Rule 2a-7 under the
Act. While a detailed and technical Rule, Rule 2a-7 has three basic
requirements: portfolio maturity, portfolio quality and portfolio
diversification. Portfolio maturity. Rule 2a-7 requires that the maximum
maturity (as determined in accordance with Rule 2a-7) of any security in a
Series' portfolio may not exceed 397 days and a Portfolio's average portfolio
maturity may not exceed 90 days. Portfolio quality. A money market fund may only
invest in First Tier and Second Tier securities (as defined in the Rule and the
Prospectus). Each Series, other than the ILA Tax-Exempt Diversified Portfolio,
ILA Tax-Exempt California Portfolio, ILA Tax-Exempt New York Portfolio, FST Tax-
Free Fund and FS Municipal Fund (the "Tax-Exempt Series"), as a matter of non-
fundamental policy only invests in First Tier securities. Portfolio
diversification. The ILA Prime Obligations, ILA Government, ILA Treasury
Obligations, ILA Money Market, ILA Federal, ILA Treasury Instruments and ILA 
Tax-Exempt Diversified Portfolios, FS Prime Obligations, FS Premium, FS
Government, FS Treasury Obligations, FS Money Market, FS Federal, FS Treasury
Instruments, FS Tax-Free and FS Municipal Funds may not invest more than 5% of
their total assets in the securities of any one issuer (except U.S. Government
securities, repurchase agreements collateralized by such securities and certain
securities subject to a guarantee or unconditional demand feature). Each of such
Series may, however, invest up to 25% of its total assets in the First Tier
Securities of a single issuer for a period of up to three business days after
the purchase thereof. ILA Tax-Exempt New York and ILA Tax-Exempt California
Portfolios, with respect to 75% of their respective total assets, may not invest
more than 5% of their total assets in the securities of any one issuer (except
U.S. Government securities, repurchase agreements collateralized by such
securities and certain securities subject to a guarantee or unconditional demand
feature); provided that such Funds may not invest more than 5% of their
respective total assets in the securities of a single issuer unless the
securities are First Tier securities. Subject to certain exceptions, immediately
after the acquisition of any demand features or guarantees (i.e., generally, the
right to sell the security at a price equal to its approximate amortized cost
(for a demand feature) or principal amount (for a guarantee) plus accrued
interest), with respect to 75% of the assets of a Series, no more than 10% of
the Series'
                                    - 39 -
<PAGE>
 
total assets may be invested in securities issued by or subject to demand
features or guarantees issued by the same issuer. In the case of the Tax-Exempt
Series (which are the only Series that are permitted to invest in Second Tier
securities), subject to certain exceptions immediately after the acquisition of
a demand feature or guarantee that is a Second Tier security, no more than 5% of
the Tax-Exempt Series' total assets may be invested in securities or demand
features or guarantees issued by the institution that issued the demand feature
or guarantee. The Tax-Exempt Series' investment in Second Tier securities that
are conduit securities, (which, generally, are municipal securities involving an
agreement or arrangement providing for payment by a person other than the issuer
of the municipal security) that are not U.S. Government securities or securities
with a guarantee by a non-controlled person, may not exceed 1% of the Series'
total assets. Also, the Tax-Exempt Series' investment in Second Tier conduit
securities of any one issuer of all issuers combined may not exceed 5% of the
Series total assets. Securities which are rated in the highest short-term rating
category by at least two Nationally Recognized Statistical Rating Organizations
("NRSROs"), or if only one NRSRO has assigned a rating, by that NRSRO, (or
unrated securities determined by the Investment Adviser to be of comparable
quality) are "First Tier Securities." Securities rated in the top two short-term
rating categories by at least two NRSROs or by the only NRSRO which has assigned
a rating, but which are not First Tier Securities (or unrated securities
determined by the Investment Adviser to be of comparable quality) are "Second
Tier Securities." Unrated securities may also be First Tier or Second Tier
securities if they are of comparable quality. In accordance with certain rules,
the rating of demand feature or guarantee of a security may be deemed to be the
rating of the underlying security. NRSROs include S&P, Moody's, Duff and Phelps,
Inc., Fitch IBCA Inc., and Thomson BankWatch, Inc. For a description of their
rating categories, see Appendix A.

          "Value" for the purposes of all investment restrictions shall mean the
value used in determining a Series' net asset value. "U.S. Government
securities" shall mean securities issued or guaranteed by the U.S. Government or
any of its agencies or instrumentalities.

          In addition to the fundamental policies mentioned above, the Board of
Trustees of the Trust has adopted the following non-fundamental policies with
respect to the Financial Square Funds which may be changed or amended by action
of the Board of Trustees without approval of shareholders. Accordingly, the
Trust may not, on the behalf of any Series:

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

          (b) Invest more than 10% of a Series' net assets in illiquid
              investments including repurchase agreements 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.

          (c) Purchase additional securities if the Series' borrowings exceed 5%
              of its net assets.

          (d) Make short sales of securities, except short sales against the
              box.

*    The fund complex consists of Goldman Sachs Trust and Goldman Sachs Variable
     Insurance Trust.  The Goldman Sachs Trust consisted of __ mutual funds,
     including the __________ series, on December 31, 1998.  Goldman Sachs
     Variable Insurance Trust consisted of 8 mutual funds.


                  THE ADVISER, DISTRIBUTOR AND TRANSFER AGENT

The Adviser
    
          GSAM, a separate operating division of Goldman Sachs, acts as the
investment adviser to the Series. Under the Management Agreement between Goldman
Sachs on behalf of GSAM and the Trust on behalf of the Series, GSAM, subject to
the supervision of the Board of Trustees of the Trust and in conformity with the
stated policies of each Series, acts as investment adviser and directs the
investments of the Series. In addition, GSAM administers the Series' business
affairs and, in connection therewith, furnishes the Trust with office facilities
and (to the extent not provided by the Trust's custodian, transfer agent, or
other organizations) clerical, recordkeeping and bookkeeping services and
maintains the financial and account records required to be maintained by the
Trust. As compensation for these services and for assuming expenses related
thereto, the Trust pays GSAM a fee, computed daily and paid monthly, at an
annual rate of .35% and .205% of each ILA Portfolio's and Financial Square
Fund's average daily net assets, respectively. GSAM has agreed to reduce or
otherwise limit the operating expenses of the respective Series, excluding
taxes, interest, brokerage and litigation, indemnification and other
extraordinary expenses, on an annualized basis, as described in the Series
Prospectuses.      


                                    - 49 -
<PAGE>
 
The amount of such reductions or limits, if any, are calculated monthly and are
based on the cumulative difference between a Series' estimated annualized
expense ratio and the expense limit for that Series. This amount will be reduced
by any prior payments related to the current fiscal year. GSAM has also
voluntarily agreed to waive a portion of its management fee for each Financial
Square Fund during the fiscal year ended December 31, 1998.

          Goldman Sachs has authorized any of its directors, partners, officers
and employees who have been elected or appointed to the position of Trustee or
officer of the Trust to serve in the capacities in which they have been elected
and appointed.

          The Trust, on behalf of each Series, is responsible for all expenses
other than those expressly borne by GSAM under the Series' Management Agreement.
The expenses borne by units of each Series include, without limitation, the fees
payable to GSAM, the fees and expenses under the Trust's distribution,
administration and service plans, the fees and expenses of the Series'
custodian, fees and expenses of the Series' transfer agent, filing fees for the
registration or qualification of units under federal or state securities laws,
expenses of the organization of the Series, taxes (including income and excise
taxes, if any), interest, costs of liability insurance, fidelity bonds,
indemnification or contribution, any costs, expenses or losses arising out of
any liability of, or claim for damages or other relief asserted against, the
Series for violation of any law, legal and auditing and tax fees and expenses
(including the cost of legal and certain accounting services rendered by
employees of Goldman Sachs with respect to the Series), expenses of preparing
and setting in type prospectuses, statements of additional information, proxy
material, reports and notices, the printing and distribution of the same to
unitholders and regulatory authorities, its proportionate share of the
compensation and expenses of its "non-interested" Trustees, and extraordinary
expenses incurred by the Series.

          The Management Agreement entered into on behalf of the ILA Portfolios
(the "ILA Management Agreement") was most recently approved by the Board of
Trustees, including the "non-interested" Trustees, on __________, 1999 and by
the unitholders of each ILA Portfolio (other than the ILA Treasury Instruments
and ILA Tax-Exempt New York Portfolios) on April 19, 1990 and by the unitholders
of the ILA Treasury Instruments and ILA Tax-Exempt New York Portfolios on June
3, 1991.  The ILA Management Agreement will remain in effect until [June 30,
1999] and will continue in effect thereafter only if such continuance is
specifically approved at least annually by a majority of the Trustees or by a
vote of a majority of the outstanding voting securities of the particular ILA
Portfolio, as defined in the Act, and, in either case, by a majority of "non-
interested" Trustees.

        The FS Management Agreement entered into on behalf of the Financial
Square Funds was most recently approved by the Trustees, including the "non-
interested" Trustees, on __________, 1999.  The Financial Square Funds'
shareholders approved the FS Management Agreement on April 21, 1997.  The FS
Management Agreement will remain in effect until [June 30, 1999] and will
continue in effect thereafter only if such continuance is specifically approved
at least annually by a majority of the Trustees or by a vote of a majority of
the outstanding voting securities of the particular Financial Square Fund (as
defined in the Act) and, in either case, by a majority of "non-interested"
Trustees.

        Prior to May 1, 1997, the Financial Square Funds then in operation had
separate investment advisory and administration agreements.  Effective May 1,
1997 the services under such agreements were combined in the Management
Agreement (the "FS Management Agreement").  The services required to be
performed for the Financial Square Funds and the combined advisory and
administration fees payable by the Financial Square Funds under the former
advisory and administration agreements are identical to the services and fees
under the FS Management Agreement.  For the fiscal years ended December 31,
1998, December 31, 1997 and December 31, 1996 the amounts of the management fee
(including both advisory and administration fees) incurred by each Financial
Square Fund (other than the FS Municipal Fund, which had not yet commenced
operations) were as follows:

     Fund commenced operations on August 1, 1997, March 3, 1997 and February 28,
     1997, respectively.


     The ILA Management and FS Management Agreements provide that GSAM shall
not be liable to an ILA Portfolio or Financial Square Fund for any error of
judgment by GSAM or for any loss sustained by the ILA Portfolio or Financial
Square Fund except in the case of GSAM's willful misfeasance, bad faith, gross
negligence or reckless disregard of duty.  Each ILA Portfolio or Financial
Square Fund may use any name derived from the name "Goldman Sachs" only so long
as the ILA Management and FS Management Agreements remain in effect.  The ILA
Management and FS Management Agreements also provide that they shall terminate
automatically if assigned and that they may be terminated with respect to any
particular ILA Portfolio or Financial Square Fund without penalty by vote of a
majority of the Trustees or a 


                                     -53-

majority of the outstanding voting securities of that ILA Portfolio or Financial
Square Fund on 60 days' written notice to GSAM or by GSAM without penalty at any
time on 90 days' (60 days with respect to a Financial Square Fund) written
notice to the Trust.

     In managing the Goldman Sachs Money Market Funds, GSAM will draw upon the
Goldman Sachs Credit Department.  The Credit Department provides superior credit
risk management for our portfolios through a team of 94 professionals who
contribute a combination of industry analysis, fund-specific expertise and
global capacity (through their local presence in foreign markets).  The credit
department continuously monitors all issuers approved for investment by the
money market funds by monitoring news stories, business developments, financial
information and ratings, as well as occasional discussion with issuer management
and rating agency analysts.  The Credit Department receives rating agency
reports and rating change information electronically and via fax as well as
reports from Goldman's Research Department.  Specifically with regards to
managing the ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-Free Money Market Fund and
FS Municipal Money Market Fund, GSAM will draw upon the extensive research
generated by Goldman Sachs' Municipal Credit Group.  The Credit Group's research
team continually reviews current information regarding the issuers of municipal
and other tax-exempt securities, with particular focus on long-term
creditworthiness, short-term liquidity, debt service costs, liability
structures, and administrative and economic characteristics.

The Distributor and Transfer Agent

     Goldman Sachs acts as principal underwriter and distributor of each
Series' units. Units of the Series are offered and sold on a continuous basis by
Goldman Sachs, acting as agent. The Distribution Agreement between Goldman Sachs
and the Trust was most recently approved by the Trustees on [July 22, 1998.]
Goldman Sachs retained approximately $______ of commissions on redemptions of
ILA Class B shares during 1998. Goldman Sachs also serves as the Series'
transfer agent. Goldman Sachs provides customary transfer agency services to the
Series, including the handling of unitholder communications, the processing of
unitholder transactions, the maintenance of unitholder account records, payment
of dividends and distributions and related functions. For these services,
Goldman Sachs receives .04% (on an annualized basis) of the average daily net
assets with respect to each class of each ILA Portfolio. Goldman Sachs currently
imposes no fees under its transfer agency agreement with the Financial Square
Funds.

     For the fiscal years ended December 31, 1998, December 31, 1997, and
December 31, 1996 the ILA Portfolios incurred transfer agency fees as follows:

     Goldman Sachs is one of the largest international investment banking firms
in the United States.  Founded in 1869, Goldman Sachs is a major investment
banking and brokerage firm providing a broad range of financing and investment
services both in the United States and abroad.  As of ________, Goldman Sachs
and its consolidated subsidiaries had assets of approximately $___ billion and
partners' capital of $___ billion.  Goldman Sachs became registered as an
investment adviser in 1981.  As of ______, Goldman Sachs, together with its
affiliates, acted as investment adviser, administrator or distributor for
approximately $___ billion in total assets.

     Activities of Goldman Sachs and Its Affiliates and Other Accounts Managed
     -------------------------------------------------------------------------
by Goldman Sachs.  The involvement of the Adviser and Goldman Sachs and their
- ----------------                                                             
affiliates, in the management of, or their interest in, other accounts and other
activities of  Goldman Sachs may present conflicts of interest with respect to
the Series or impede their investment activities.

     Goldman Sachs and its affiliates, including, without limitation, the
Adviser and its advisory affiliates have proprietary interests in, and may
manage or advise with respect to, accounts or funds (including separate accounts
and other funds and collective investment vehicles) which have investment
objectives similar to those of the Series and/or which engage in transactions in
the same types of securities, currencies and instruments as the Series.  Goldman
Sachs and its affiliates are major participants in the global currency,
equities, swap and fixed-income markets, in each case both on a proprietary
basis and for the accounts of customers. As such, Goldman Sachs and its
affiliates are actively engaged in transactions in the same securities,
currencies, and instruments in which the Series invest.  Such activities could
affect the prices and availability of the securities, currencies, and
instruments in which the Series invest, which could have an adverse impact on
each Portfolio's performance.  Such transactions, particularly in respect of
proprietary accounts or customer accounts other than those included in the
Adviser's and its advisory affiliates' asset management activities, will be
executed independently of the Portfolios' transactions and thus at prices or
rates that may be more or less favorable.  When the Adviser and its advisory
affiliates seek to purchase or sell the same assets for their managed accounts,
including the Series, the assets actually purchased or sold may be allocated
among the accounts on a basis determined in its good faith discretion to be
equitable.  In some cases, this system may adversely affect the size or the
price of the assets purchased or sold for the Series.

     From time to time, the Series' activities may be restricted because of
regulatory restrictions applicable to Goldman Sachs and its affiliates, and/or
their internal policies designed to comply with such restrictions.  As a result,
there may be periods, for example, when the Adviser, and/or its affiliates, will
not initiate or recommend certain types of transactions in certain securities or
instruments with respect to which the Adviser and/or its affiliates are
performing services or when position limits have been reached.

     In connection with their management of the Series, the Adviser may have
access to certain fundamental analysis and proprietary technical models
developed by Goldman Sachs and other affiliates.  The Adviser will not be under
any obligation, however, to effect transactions on behalf of the Series in
accordance with such analysis and models.  In addition, neither Goldman 


                                     -55-
<PAGE>
 
Sachs nor any of its affiliates will have any obligation to make available any
information regarding their proprietary activities or strategies, or the
activities or strategies used for other accounts managed by them, for the
benefit of the management of the Series. The proprietary activities or portfolio
strategies of Goldman Sachs and its affiliates or the activities or strategies
used for accounts managed by them or other customer accounts could conflict with
the transactions and strategies employed by the Adviser in managing the Series.

     The results of each Series' investment activities may differ significantly
from the results achieved by the Adviser and its affiliates for their
proprietary accounts or other accounts (including investment companies or
collective investment vehicles) managed or advised by them.  It is possible that
Goldman Sachs and its affiliates and such other accounts will achieve investment
results which are substantially more or less favorable than the results achieved
by a Series.  Moreover, it is possible that a Series will sustain losses during
periods in which Goldman Sachs and its affiliates achieve significant profits on
their trading for proprietary or other accounts.  The opposite result is also
possible.

     An investment policy committee which may include partners of Goldman Sachs
and its affiliates may develop general policies regarding a Series' activities,
but will not be involved in the day-to-day management of such Series.  In such
instances, those individuals may, as a result, obtain information regarding the
Series' proposed investment activities which is not generally available to the
public.  In addition, by virtue of their affiliation with Goldman Sachs, any
such member of an investment policy committee will have direct or indirect
interests in the activities of Goldman Sachs and its affiliates in securities,
currencies and investments similar to those in which the Series invests.

     In addition, certain principals and certain of the employees of the
Adviser are also principals or employees of Goldman Sachs or its affiliated
entities.  As a result, the performance by these principals and employees of
their obligations to such other entities may be a consideration of which
investors in the Series should be aware.

     The Adviser may enter into transactions and invest in instruments in which
customers of Goldman Sachs serve as the counterparty, principal or issuer.  In
such cases, such party's interests in the transaction will be adverse to the
interests of the Series, and such party may have no  incentive to assure that
the Series obtain the best possible prices or terms in connection with the
transactions.  Goldman Sachs and its affiliates may also create, write or issue
derivative instruments for customers of Goldman Sachs or its affiliates, the
underlying securities, currencies or instruments of which may be those in which
the Series invest or which may be based on the performance of a Series.  The
Series may, subject to applicable law, purchase investments which are the
subject of an underwriting or other distribution by Goldman Sachs or its
affiliates and may also enter into transactions with other clients of Goldman
Sachs or its affiliates where such other clients have interests adverse to those
of the Series.  At times, these activities may cause departments of Goldman
Sachs or its affiliates to give advice to clients that may cause these clients
to take actions adverse to the interests of the client.  To the extent
affiliated transactions are permitted, the Series will deal with Goldman Sachs
and its affiliates on an arms-length basis.


                                     -56-

     Each Series will be required to establish business relationships with its
counterparties based on the Series' own credit standing. Neither Goldman Sachs
nor its affiliates will have any obligation to allow their credit to be used in
connection with a Series' establishment of its business relationships, nor is it
expected that a Series' counterparties will rely on the credit of Goldman Sachs
or any of its affiliates in evaluating the Series' creditworthiness.

     From time to time, Goldman Sachs or any of its affiliates may, but is not
required to, purchase and hold shares of a Series in order to increase the
assets of the Series.  Increasing a Series' assets may enhance investment
flexibility and diversification and may contribute to economies of scale that
tend to reduce a Series' expense ratio.  Goldman Sachs reserves the right to
redeem at any time some or all of the shares of a Series acquired for its own
account.  A large redemption of shares of a Series by Goldman Sachs could
significantly reduce the asset size of the Series, which might have an adverse
effect on a Series' investment flexibility, portfolio diversification and
expense ratio.  Goldman Sachs will consider the effect of redemptions on a
Series and other unitholders in deciding whether to redeem its units.


                             PORTFOLIO TRANSACTIONS

     GSAM places the portfolio transactions of the Series and of all other
accounts managed by GSAM for execution with many firms.  GSAM uses its best
efforts to obtain execution of portfolio transactions at prices which are
advantageous to each Series and at reasonably competitive spreads or (when a
disclosed commission is being charged) at reasonably competitive commission
rates.  In seeking such execution, GSAM will use its best judgment in evaluating
the terms of a transaction, and will give consideration to various relevant
factors, including without limitation the size and type of the transaction, the
nature and character of the market for the security, the confidentiality, speed
and certainty of effective execution required for the transaction, the general
execution and operational capabilities of the broker-dealer, the general
execution and operational capabilities of the firm, the reputation, reliability,
experience and financial condition of the firm, the value and quality of the
services rendered by the firm in this and other transactions, and the
reasonableness of the spread or commission, if any.  Securities purchased and
sold by the Series are generally traded in the over-the-counter market on a net
basis (i.e., without commission) through broker-dealers and banks acting for
their own account rather than as brokers, or otherwise involve transactions
directly with the issuer of such securities.

     Goldman Sachs is active as an investor, dealer and/or underwriter in many
types of municipal and money market instruments.  Its activities in this regard
could have some effect on the markets for those instruments which the Series
buy, hold or sell.  An order has been granted by the SEC under the Act which
permits the Series to deal with Goldman Sachs in transactions in certain taxable
securities in which Goldman Sachs acts as principal.  As a result, the Series
may trade with Goldman Sachs as principal subject to the terms and conditions of
such exemption.

     Under the Act, the Series are prohibited from purchasing any instrument of
which Goldman Sachs is a principal underwriter during the existence of an
underwriting or selling syndicate relating to such instrument, absent an
exemptive order (the order referred to in the 


                                     -57-
<PAGE>
 
preceding paragraph will not apply to such purchases) or the adoption of and
compliance with certain procedures under such Act. The Trust has adopted
procedures which establish, among other things, certain limitations on the
amount of debt securities that may be purchased in any single offering and on
the amount of the Trust's assets that may be invested in any single offering.
Accordingly, in view of Goldman Sachs' active role in the underwriting of debt
securities, a Series' ability to purchase debt securities in the primary market
may from time to time be limited.

     In certain instances there may be securities which are suitable for more
than one Series as well as for one or more of the other clients of GSAM.
Investment decisions for each Series and for GSAM's other clients are made with
a view to achieving their respective investment objectives.  It may develop that
a particular security is bought or sold for only one client even though it might
be held by, or bought or sold for, other clients. Likewise, a particular
security may be bought for one or more clients when one or more other clients
are selling that same security.  Some simultaneous transactions are inevitable
when several clients receive investment advice from the same investment adviser,
particularly when the same security is suitable for the investment objectives of
more than one client.  When two or more clients are simultaneously engaged in
the purchase or sale of the same security, the securities are allocated among
clients in a manner believed to be equitable to each.  It is recognized that in
some cases this system could have a detrimental effect on the price or volume of
the security in a particular transaction as far as a Series is concerned.  Each
Series believes that over time its ability to participate in volume transactions
will produce better executions for the Series.

     During the fiscal year ended December 31, 1998, the Trust acquired and
sold securities of its regular broker/dealers: _______________________________.

     As of December 31, 1998, each ILA Portfolio held the following amounts of
securities of its regular broker/dealers, as defined in Rule 10b-1 under the
Act, or their parents ($ in thousands): ___________________________________.

     As of December 31, 1998, each Financial Square Fund held the following
amounts of securities of its regular broker/dealers as defined in Rule 10b-1
under the Investment Company Act, or their parents ($ in thousands): _________.


                                NET ASSET VALUE

     The net asset value per unit of each Series (except for FS Government
Fund, FS Premium Fund and FS Treasury Obligations Fund) is determined by the
Series' custodian as of the close of regular trading on the New York Stock
Exchange (normally, but not always, 4:00 p.m. New York time) (in the case of the
FS Government Fund, FS Premium Fund and FS Treasury Obligations Fund, net asset
value is determined normally, but not always, at 5:00 p.m. New York time) on
each Business Day.  A Business Day means any day on which the New York Stock
Exchange is open, except for days on which Chicago, Boston or New York banks are
closed for local holidays.  Such holidays include: New Year's Day, Martin Luther
King, Jr. Day, Presidents' Day, 


                                     -58-
<PAGE>
 
Good Friday, Memorial Day, the Fourth of July, Labor Day, Columbus Day,
Veteran's Day, Thanksgiving Day and Christmas Day.

     Each Series' securities are valued using the amortized cost method of
valuation in an effort to maintain a constant net asset value of $ 1.00 per
unit, which the Board of Trustees has determined to be in the best interest of
each Series and its unitholders.  This method involves valuing a security at
cost on the date of acquisition and thereafter assuming a constant accretion of
a discount or amortization of a premium to maturity, regardless of the impact of
fluctuating interest rates on the market value of the instrument.  While this
method provides certainty in valuation, it may result in periods during which
value, as determined by amortized cost, is higher or lower than the price a
Series would receive if it sold the instrument.  During such periods, the yield
to an investor in a Series may differ somewhat from that obtained in a similar
investment company which uses available market quotations to value all of its
portfolio securities.  During periods of declining interest rates, the quoted
yield on units of a Series may tend to be higher than a like computation made by
a fund with identical investments utilizing a method of valuation based upon
market prices and estimates of market prices for all of its portfolio
instruments.  Thus, if the use of amortized cost by a Series resulted in a lower
aggregate portfolio value on a particular day, a prospective investor in the
Series would be able to obtain a somewhat higher yield if he or she purchased
units of the Series on that day, than would result from investment in a fund
utilizing solely market values, and existing investors in the Series would
receive less investment income.  The converse would apply in a period of rising
interest rates.

     The Trustees have established procedures designed to stabilize, to the
extent reasonably possible, each Series' price per unit as computed for the
purpose of sales and redemptions at $1.00.  Such procedures include review of
each Series by the Trustees, at such intervals as they deem appropriate, to
determine whether the Series' net asset value calculated by using available
market quotations (or an appropriate substitute which reflects market
conditions) deviates from $1.00 per unit based on amortized cost, as well as
review of methods used to calculate the deviation.  If such deviation exceeds
1/2 of 1%, the Trustees will promptly consider what action, if any, will be
initiated.  In the event the Trustees determine that a deviation exists which
may result in material dilution or other unfair results to investors or existing
unitholders, they will take such corrective action as they regard to be
necessary and appropriate, including the sale of portfolio instruments prior to
maturity to realize capital gains or losses or to shorten average portfolio
maturity; withholding part or all of dividends or payment of distributions from
capital or capital gains; redemptions of units in kind; or establishing a net
asset value per unit by using available market quotations or equivalents.  In
addition, in order to stabilize the net asset value per unit at $1.00 the
Trustees have the authority (1) to reduce or increase the number of units
outstanding on a pro rata basis, and (2) to offset each unitholder's pro rata
portion of the deviation between the net asset value per unit and $1.00 from the
unitholder's accrued dividend account or from future dividends. Each Series may
hold cash for the purpose of stabilizing its net asset value per unit.  Holdings
of cash, on which no return is earned, would tend to lower the yield on such
Series' units.

     In order to continue to use the amortized cost method of valuation for
each Series' investments, the Series must comply with Rule 2a-7.  See
"Investment Restrictions."

                                     -59-
<PAGE>
 
     The proceeds received by each Series for each issue or sale of its units,
and all net investment income, realized and unrealized gain and proceeds
thereof, subject only to the rights of creditors, will be specifically allocated
to such Series and constitute the underlying assets of that Series.  The
underlying assets of each Series will be segregated on the books of account, and
will be charged with the liabilities in respect to such Series and with a share
of the general liabilities of the Trust.  Expenses with respect to the Series
are to be allocated in proportion to the net asset values of the respective
Series except where allocations of direct expenses can otherwise be fairly made.
In addition, within each Series, ILA Units, ILA Administration Units, ILA
Service Units, ILA Class B and Class C Units, ILA Cash Management Shares, FST
Shares, FST Administration Shares, FST Service Shares and FST Preferred Shares
(if any) will be subject to different expense structures (see "Organization and
Capitalization").


                                  REDEMPTIONS

     The Trust may suspend the right of redemption of units of a Series and may
postpone payment for any period: (i) during which the New York Stock Exchange is
closed for regular trading other than customary weekend and holiday closings or
during which trading on the New York Stock Exchange is restricted, (ii) when the
SEC determines that a state of emergency exists which may make payment or
transfer not reasonably practicable, (iii) as the SEC may by order permit for
the protection of the unitholders of the Trust or (iv) at any other time when
the Trust may, under applicable laws and regulations, suspend payment on the
redemption of the Series' units.

     The Trust agrees to redeem units of each Series solely in cash up to the
lesser of $250,000 or 1% of the net asset value of the Series during any 90-day
period for any one unitholder.  The Trust reserves the right to pay other
redemptions, either total or partial, by a distribution in kind of securities
(instead of cash) from the applicable Series' portfolio.  The securities
distributed in such a distribution would be valued at the same value as that
assigned to them in calculating the net asset value of the units being redeemed.
If a unitholder receives a distribution in kind, he or she should expect to
incur transaction costs when he or she converts the securities to cash.

     A FST shareholder of any Financial Square Fund with balances in excess of
$100 million may elect to have a special account with State Street for the
purpose of redeeming shares from its account in that Series by check.  When
State Street receives a completed signature card and authorization form, the
shareholder will be provided with a supply of checks.  Checks drawn on this
account may be payable to the order of any person in any amount of $500 or more,
but cannot be certified.  The payee of the check may cash or deposit it like any
other check drawn on a bank.  When such a check is presented to State Street for
payment, a sufficient number of full and fractional shares will be redeemed to
cover the amount of the check.  Cancelled checks will be returned to the
shareholder by State Street.  The Trust and Goldman Sachs each reserves the
right to waive the minimum requirement.

     The check redemption privilege enables a shareholder to receive the
dividends declared on the shares to be redeemed until such time as the check is
processed.  Because of this feature, the check redemption privilege may not be
used for a complete liquidation of an account.  If the 


                                     -60-
<PAGE>
 
amount of a check is greater than the value of shares held in the shareholder's
account, the check will be returned unpaid, and the shareholder may be subject
to extra charges.

     Goldman Sachs reserves the right to impose conditions on, limit the
availability of or terminate the check redemption privilege at any time with
respect to a particular shareholder or Service Organization in general.  The
Trust and State Street reserve the right at any time to suspend the check
redemption privilege and intend to do so in the event that federal legislation
or regulations impose reserve requirements or other restrictions deemed by the
Trustees to be adverse to the interests of the Series.


                        CALCULATION OF YIELD QUOTATIONS

     Each Series' yield quotations are calculated by a standard method
prescribed by the rules of the SEC.  Under this method, the yield quotation is
based on a hypothetical account having a balance of exactly one unit at the
beginning of a seven-day period.

     Yield, effective yield, tax-equivalent yield and tax-equivalent effective
yield are calculated separately for each class of units of a Series.  Each type
of unit is subject to different fees and expenses and may have differing yields
for the same period.

     The yield quotation is computed as follows: the net change, exclusive of
capital changes and income other than investment income (i.e., realized gains
and losses from the sale of securities and unrealized appreciation and
depreciation), in the value of a hypothetical pre-existing account having a
balance of one unit at the beginning of the base period is determined by
dividing the net change in account value by the value of the account at the
beginning of the base period.  This base period return is then multiplied by
365/7 with the resulting yield figure carried to the nearest 100th of 1%.  Such
yield quotation shall take into account all fees that are charged to a Series.

     Each Series also may advertise a quotation of effective yield for a 7-
calendar day period.  Effective yield is computed by compounding the
unannualized base period return determined as in the preceding paragraph by
adding 1 to that return, raising the sum to the 365/7 power and subtracting one
from the result, according to the following formula:

     Effective Yield = [(base period return + 1)365/7] - 1

     The ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio, ILA Tax-Exempt New York Portfolio, FS Federal Fund, FS Tax-Free Fund
and FS Premium Fund may also advertise a tax-equivalent yield and tax-equivalent
effective yield. Tax equivalent yield is computed by dividing that portion of a
Series' yield (as computed above) which is tax-exempt by one minus a stated
income tax rate and adding the quotient to that portion, if any, of the yield of
the Series that is not tax-exempt. Tax-equivalent effective yield is computed by
dividing that portion of a Series' effective yield (as computed above) which is
tax-exempt by one minus a

                                     -61-
<PAGE>
 
stated income tax rate and adding the quotient to that portion, if any, of the
effective yield of the Series that is not tax-exempt.

     Unlike bank deposits or other investments which pay a fixed yield or
return for a stated period of time, the return for a Series will fluctuate from
time to time and does not provide a basis for determining future returns.
Return is a function of portfolio quality, composition, maturity and market
conditions as well as of the expenses allocated to each Series.  The return of a
Series may not be comparable to other investment alternatives because of
differences in the foregoing variables and differences in the methods used to
value portfolio securities, compute expenses and calculate return.

     The yield, effective yield, tax-equivalent yield and tax-equivalent
effective yield of each ILA Portfolio with respect to ILA Units, ILA
Administration Units, ILA Service Units, ILA Class B Units, ILA Class C Units
and Cash Management Shares for the seven-day period ended December 31, 1998 were

     The quotations of tax-equivalent yield set forth above for the seven-day
period ended December 31, 1998 are based on a federal marginal tax rate of 40.8%
(adjusted for the 3% phase out of itemized deductions for individuals at high
income levels).

     With respect to the ILA Tax-Exempt California Portfolio, the California top
marginal State personal income tax rate of 5.62% (adjusted for the federal
income tax benefit) is being assumed in addition to the 40.8% federal tax rate,
for a combined tax rate of 46.42%.  With respect to the ILA Tax-Exempt New York
Portfolio, the tax-equivalent and tax-equivalent effective yields are being
shown under three scenarios.  The first scenario assumes, as noted above, a
federal marginal tax rate of 40.8%, the second scenario assumes a New York top
marginal State personal income tax rate of 4.14% (adjusted for the federal
income tax benefit), for a combined effective tax rate of 44.94%.  The third
scenario assumes a New York City top marginal personal income tax rate of 2.69%
(adjusted for the federal income tax benefit) in addition to the above federal
and New York State tax rates, for a combined effective tax rate of 47.63%.  The
combined tax rates assume full deductibility of state and, if applicable, city
taxes in computing federal tax liability.

     In addition, from time to time, advertisements or information may include a
discussion of asset allocation models developed or recommended 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 form a part of
such an asset allocation strategy.  Such advertisements and information may also
include a discussion of GSAM's current economic outlook and domestic and
international market views and recommend periodic tactical modifications to
current asset allocation strategies. Such advertisements and information may
include other material which highlight or summarize the services provided in
support of an asset allocation program.

     From time to time any Series may publish an indication of its past
performance as measured by independent sources such as (but not limited to)
Lipper Analytical Services, Incorporated, Weisenberger Investment Companies
Service, Donoghue's Money Fund Report, Barron's, Business Week, Changing Times,
Financial World, Forbes, Money, Morningstar Mutual Funds, Micropal, Personal
Investor, Sylvia Porter's Personal Finance, and The Wall Street Journal.

     The Trust may also advertise information which has been provided to the
NASD for publication in regional and local newspapers. In addition, the Trust
may from time to time


                                     -68-
<PAGE>
 
advertise a Series' performance relative to certain indices and benchmark
investments, including (without limitation): inflation and interest rates,
certificates of deposit (CDs), money market deposit accounts (MMDAs), checking
accounts, savings accounts and repurchase agreements. The Trust may also compare
a Series' performance with that of other mutual funds with similar investment
objectives.

     The composition of the investments in such mutual funds, comparative
indices and the characteristics of such benchmark investments are not identical
to, and in some cases are very different from, those of a Series. Indices and
averages are generally unmanaged and the items included in the calculations of
such indices and averages may not be identical to the formulas used by a Series
to calculate its performance data.

     A Series' performance data will be based on historical results and is not
intended to indicate future performance.  A Series' performance will vary based
on market conditions, portfolio expenses, portfolio investments and other
factors. Return for a Series will fluctuate unlike certain bank deposits or
other investments which pay a fixed yield or return.

     The Trust may also, at its discretion, from time to time make a list of a
Series' holdings available to investors upon request.  The Trust may from time
to time summarize the substance of discussions contained in shareholder reports
in advertisements and publish the Adviser's views as to markets, the rationale
for a Series' investments and discussions of a Fund's current holdings.

     In addition, from time to time, quotations from articles from financial and
other publications, such as those listed above, may be used in advertisements,
sales literature and in reports to unitholders.


                                TAX INFORMATION

     Each Series has elected or intends to qualify and elect to be treated and
to qualify as a separate regulated investment company under Subchapter M of the
Internal Revenue Code of 1986, as amended, (the "Code"). Such qualification does
not involve supervision of management or investment practices or policies by any
governmental agency or bureau.

     In order to qualify as a regulated investment company, each Series must,
among other things, (a) derive at least 90% of its gross income for the taxable
year from dividends, interest, payments with respect to securities loans and
gains from the sale or other disposition of stock or securities or certain other
investments (the "90% Test"); and (b) diversify its holdings so that, at the
close of each quarter of its taxable year, (i) at least 50% of the market value
of the Series' total gross assets is represented by cash and cash items
(including receivables), U.S. Government securities, securities of other
regulated investment companies and other securities limited, in respect of any
one issuer, to an amount not greater in value than 5% of the value of the
Series' total assets and not more than 10% of the outstanding voting securities
of such issuer, and (ii) not more than 25% of the value of the Series' total
(gross) assets is invested in the securities (other than U.S. Government
securities and securities of other regulated investment companies) of any one
issuer or two or more issuers controlled by the Series and engaged in the same,
similar or


                                     -69-
<PAGE>
 
related trades or businesses.  For purposes of these requirements,
participation interests will be treated as securities, and the issuer will be
identified on the basis of market risk and credit risk associated with any
particular interest.  Certain payments received with respect to such interests,
such as commitment fees and certain facility fees, may not be treated as income
qualifying under the 90% test.

  Each Series, as a regulated investment company, will not be subject to federal
income tax on any of its net investment income and net realized capital gains
that are distributed to unitholders with respect to any taxable year in
accordance with the Code's timing and other requirements, provided that the
Series distributes at least 90% of its investment company taxable income
(generally, all of its net taxable income other than "net capital gain," which
is the excess of net long-term capital gain over net short-term capital loss)
for such year and, in the case of any Series that earns tax-exempt interest, at
least 90% of the excess of the tax-exempt interest it earns over certain
disallowed deductions.  A Series will be subject to federal income tax at
regular corporate rates on any investment company taxable income or net capital
gain that it does not distribute for a taxable year. In order to avoid a
nondeductible 4% federal excise tax, each Series must distribute (or be deemed
to have distributed) by December 31 of each calendar year at least 98% of its
taxable ordinary income for such year, at least 98% of the excess of its capital
gains over its capital losses (generally computed on the basis of the one-year
period ending on October 31 of such year), and all taxable ordinary income and
the excess of capital gains over capital losses for the previous year that were
not distributed in such year and on which the Series paid no federal income tax.

  Dividends paid by a Series from taxable net investment income (including
income attributable to accrued market discount and a portion of the discount on
certain stripped tax-exempt obligations and their coupons) and the excess of net
short-term capital gain over net long-term capital loss will be treated as
ordinary income in the hands of unitholders.  Such distributions will not
qualify for the corporate dividends-received deduction. Dividends paid by a
Series from the excess of net long-term capital gain (if any) over net short-
term capital loss are taxable to unitholders as long-term capital gain,
regardless of the length of time the units of a Series have been held by such
unitholders, and also will not qualify for the corporate dividends-received
deduction.  A Series' net realized capital gains for a taxable year are computed
by taking into account realized capital losses, including any capital loss
carryforward of that Series.  At December 31, 1998, the following Series had
approximately the following amounts of capital loss carryforwards:

interest received by them and properly designated as "exempt-interest dividends"
will generally be exempt from regular federal income tax, provided that at least
50% of the value of the applicable Series' total assets at the close of each
quarter of its taxable year consists of tax-exempt obligations, i.e.,
                                                                - -  
obligations described in Section 103(a) of the Code (not including units of
other regulated investment companies that may pay exempt-interest dividends,
because such units are not treated as tax-exempt obligations for this purpose).
It is expected that each of these five Series will meet this 50% test each year.
Dividends paid by the other Series from any tax-exempt interest they may receive
will not be tax-exempt, because they will not satisfy the 50% requirement
described in the preceding sentence. A portion of any tax-exempt distributions
attributable to interest on certain "private activity bonds," if any, received
by a Series may constitute a tax preference items and may give rise to, or
increase liability under, the alternative minimum tax for particular
unitholders. In addition, tax-exempt distributions of the Series may be
considered in computing the "adjusted current earnings" preference item of their
corporate unitholders in determining the corporate alternative minimum tax. To
the extent that the ILA Tax-Exempt Diversified, ILA Tax-Exempt California, ILA
Tax-Exempt New York Portfolios and FS Tax-Free and FS Municipal Funds invest in
certain short-term instruments, including repurchase agreements, the interest on
which is not exempt from Federal income tax, or earn other taxable income any
distributions of income from such investments or other taxable income will be
taxable to unitholders as ordinary income. All or substantially all of any
interest on indebtedness incurred directly or indirectly to purchase or carry
units of the Series will generally not be deductible. The availability of tax-
exempt obligations and the value of the Series may be affected by restrictive
tax legislation enacted in recent years.

  In purchasing municipal obligations, the ILA Tax-Exempt Diversified, ILA Tax-
Exempt California, ILA Tax-Exempt New York Portfolios, FS Tax-Free and FS
Municipal Funds rely on opinions of nationally-recognized bond counsel for each
issue as to the excludability of interest on such obligations from gross income
for federal income tax purposes and, where applicable, the tax-exempt nature of
such interest under the personal income tax laws of a particular state.  These
Series do not undertake independent investigations concerning the tax-exempt
status of such obligations, nor do they guarantee or represent that bond
counsels' opinions are correct.

  Distributions of net investment income and net realized capital gains will be
taxable as described above, whether received in units or in cash.  Unitholders
electing to receive distributions in the form of additional units will have a
cost basis in each unit so received equal to the amount of cash they would have
received had they elected to receive cash.

  Certain series may be subject to foreign taxes on their income (possibly
including, in some cases, capital gains) from securities.  Tax conventions
between certain countries and the U.S. may reduce or eliminate such taxes in
some cases.

  Redemptions (including exchanges) and other dispositions of units in
transactions that are treated as sales for tax purposes will generally not
result in taxable gain or loss, provided that the Series successfully maintain a
constant net asset value per share, but a loss may be recognized to the extent a
CDSC is imposed on the redemption or exchange of ILA Class B or Class C Units.
All or a portion of such a loss may be disallowed under applicable Code
provisions in certain circumstances. Unitholders should consult their own tax
advisors with reference to their 

                                     -71-
<PAGE>
 
circumstances to determine whether a redemption, exchange, or other disposition
of Series Units is properly treated as a sale for tax purposes.

  All distributions (including exempt-interest dividends) whether received in
units or cash, must be reported by each unitholder who is required to file a
federal income tax return. The Series will inform unitholders of the federal
income tax status of their distributions after the end of each calendar year,
including, in the case of the ILA Tax-Exempt Diversified Portfolio, ILA Tax-
Exempt California Portfolio, ILA Tax-Exempt New York Portfolio, FS Tax-Free Fund
and FS Municipal Fund the amounts that qualify as exempt-interest dividends and
any portions of such amounts that constitute tax preference items under the
federal alternative minimum tax.  Unitholders who receive exempt-interest
dividends and have not held their units of the applicable Series for its entire
taxable year may have designated as tax-exempt or as a tax preference item a
percentage of their distributions which is not exactly equal to a proportionate
share of the amount of tax-exempt interest or tax preference income earned
during the period of their investment in such Series.  Each unitholder should
consult his or her own tax advisor to determine the tax consequences of an
investment in a Series in the unitholder's own state and locality.


     An investment in a Series that pays primarily exempt-interest dividends is
not intended to constitute a balanced investment program.  Units of such Series
would not be suitable for tax-exempt institutions and may not be suitable for
retirement plans qualified under Section 401 of the Code, H.R. 10 plans and
individual retirement accounts because such plans and accounts are generally
tax-exempt and, therefore, not only would the Unitholder not gain any additional
benefit from the Series' dividends being tax-exempt, but such dividends would be
ultimately taxable to the beneficiaries when distributed.  In addition, a Series
that pays primarily exempt-interest dividends may not be an appropriate
investment for entities which are "substantial users" of facilities financed by
"private activity bonds" or "related persons" thereof.  "Substantial user" is
defined under U.S. Treasury Regulations to include a non-exempt person who (i)
regularly uses a part of such facilities in his or her trade or business and
whose gross revenues derived with respect to the facilities financed by the
issuance of bonds are more than 5% of the total revenues derived by all users of
such facilities, (ii) occupies more than 5% of the usable area of such
facilities or (iii) are persons for whom such facilities or a part thereof were
specifically constructed, reconstructed or acquired.  "Related persons" included
certain related natural persons, affiliated corporations, a partnership and its
partners and an S corporation and its shareholders.

  The foregoing discussion relates solely to U.S. federal income tax law as it
applies to U.S. persons (i.e., U.S. citizens and residents and U.S. domestic
corporations, partnerships, trusts and estates) subject to tax under such law.
The discussion does not address special tax rules applicable to certain classes
of investors, such as tax-exempt entities, insurance companies and financial
institutions.  Each unitholder who is not a U.S. person should consult his or
her tax adviser regarding the U.S. and non-U.S. tax consequences of ownership of
units of a Series, including the possibility that such a unitholder may be
subject to a U.S. nonresident alien withholding tax at a rate of 30% (or at a
lower rate under an applicable U.S. income tax treaty) on certain distributions
from a Series and, if a current IRS Form W-8 or acceptable substitute is not on
file with the Series, may be subject to backup withholding on certain payments.

State and Local


  The Trust may be subject to state or local taxes in jurisdictions in which the
Trust may be deemed to be doing business.  In addition, in those states or
localities which have income tax laws, the treatment of a Series and its
unitholders under such laws may differ from their treatment under Federal income
tax laws, and an investment in the Series may have tax consequences for
unitholders that are different from those of a direct investment in the Series'
securities.  Unitholders should consult their own tax advisers concerning these
matters. For example, in such states or localities it may be appropriate for
unitholders to review with their tax advisers the state income and, if
applicable, intangible property tax consequences of investments by the Series in
securities issued by the particular state or the U.S. Government or its various
agencies or instrumentalities, because many states (i) exempt from personal
income tax distributions made by regulated investment companies from interest on
obligations of the particular state or on direct U.S. Government obligations
and/or (ii) exempt from intangible property tax the value of the units of such
companies attributable to such obligations, subject to certain state-specific
requirements and/or limitations. See also the discussion below of these
applicable provisions in California and New York.

  Provided that the Series qualify as regulated investment companies and incur
no federal income tax liability, the Series may still be subject to New York
State and City minimum taxes, which are small in amount.

  California State Taxation.  The following discussion of California tax law
assumes that the ILA Tax-Exempt California Portfolio will be qualified as a
regulated investment company under Subchapter M of the Code and will be
qualified thereunder to pay exempt-interest dividends.  The ILA Tax-Exempt
California Portfolio intends to qualify for each taxable year under California
law to pay "exempt-interest dividends" which will be exempt from the California
personal income tax.

  Individual unitholders of the ILA Tax-Exempt California Portfolio who reside
in California will not be subject to California personal income tax on
distributions received from the Portfolio to the extent such distributions are
exempt-interest dividends attributable to interest on obligations the interest
on which is exempt from California personal income tax provided that the
Portfolio satisfies the requirement of California law that at least 50% of its
assets at the close of each quarter of its taxable year be invested in such
obligations and properly designates such exempt-interest dividends under
California Law. Distributions from the ILA Tax-Exempt California Portfolio which
are attributable to sources other than those described in the second preceding
sentence will generally be taxable to such unitholders as ordinary income.
Moreover, California legislation which incorporates Subchapter M of the Code
provides that capital gain dividends may be treated as long-term capital gains.
Such gains are currently subject to personal income tax at ordinary income tax
rates.  Capital gains that are retained by the Portfolio will be taxed to that
Portfolio, and California residents will receive no California personal income
tax credit for such tax.  Distributions other than exempt-interest dividends are
includable in income subject to the California alternative minimum tax.

                                     -73-
<PAGE>
 
  Distributions from investment income and long-term and short-term capital
gains will generally not be excluded from taxable income in determining
California corporate franchise taxes for corporate unitholders and will be
treated as ordinary dividend income for such purposes.  In addition, such
distributions may be includable in income subject to the alternative minimum
tax.

  Interest on indebtedness incurred or continued by unitholders to purchase or
carry units of the ILA Tax-Exempt California Portfolio will not be deductible
for California personal income tax purposes.

  In addition, any loss realized by a unitholder of the ILA Tax-Exempt
California Portfolio upon the sale of units held for six months or less may be
disallowed to the extent of any exempt-interest dividends received with respect
to such units. Moreover, any loss realized upon the redemption of units within
six months from the date of purchase of such units and following receipt of a
long-term capital gains distribution will be treated as long-term capital loss
to the extent of such long-term capital gains distribution.  Finally, any loss
realized upon the redemption of units within thirty days before or after the
acquisition of other units of the same Portfolio may be disallowed under the
"wash sale" rules.

  New York City and State Taxation.  Individual unitholders who are residents of
New York State will be able to exclude for New York State income tax purposes
that portion of the exempt-interest dividends properly designated as such from
the ILA Tax-Exempt New York Portfolio which is derived from interest on
obligations of New York State and its political subdivisions and obligations of
Puerto Rico, the U.S. Virgin Islands and Guam.  Exempt-interest dividends may be
properly designated as such only if, as anticipated, at least 50% of the value
of the assets of the Portfolio are invested at the close of each quarter of its
taxable year in obligations of issuers the interest on which is excluded from
gross income for federal income tax purposes.  Individual unitholders who are
residents of New York City will also be able to exclude such income for New York
City income tax purposes.  Interest on indebtedness incurred or continued by a
shareholder to purchase or carry shares of the ILA Tax-Exempt New York Portfolio
is not deductible for New York State or New York City personal income tax
purposes.

  Long-term capital gains, if any, that are distributed by the ILA Tax-Exempt
New York Portfolio and are properly designated as capital gain dividends will be
treated as capital gains for New York State and City income tax purposes in the
hands of New York State and New York City residents

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

  This discussion of the tax treatment of the Portfolio and its unitholders is
based on the tax laws in effect as of the date of this Statement of Additional
Information.

                        ORGANIZATION AND CAPITALIZATION
                                        

  The Series were reorganized from series of a Massachusetts business trust 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 units exists,
each class or series must be preferred over all other classes or series in
respect of assets specifically allocated to such class or series.  The Trustees
also have authority to classify and reclassify any series of units into one or
more classes of units.  As of the date of this Statement of Additional
Information, the Trustees have authorized the issuance of up to three classes of
units of each of the ILA Portfolios: ILA Units, ILA Administration Units and ILA
Service Units.  In addition, the Trustees have authorized a fourth and fifth
class of units, ILA Class B Units and ILA Class C Units, with respect to the
Prime Obligations Portfolio.  The Trustees have also authorized Cash Management
Shares of the ILA Prime Obligations Portfolio, ILA Money Market Portfolio, ILA
Government Portfolio, ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt
California Portfolio and ILA Tax-Exempt New York Portfolio.  As of the date of
this Statement of Additional Information, the Trustees have authorized the
issuance of up to four classes of shares of each of the Financial Square Funds:
FST Shares, FST Service Shares, FST Administration Shares and FST Preferred
Shares.

  Each ILA Unit, ILA Administration Unit, ILA Service Unit, ILA Class B Unit,
ILA Class C Unit, Cash Management Share, FST Share, FST Administration Share,
FST Service Share and FST Preferred Share of a Series represents an equal
proportionate interest in the assets belonging to that Series.  It is
contemplated that most units (other than ILA Class B or Class C Units) will be
held in accounts of which the record owner is a bank or other institution
acting, directly or through an agent, as nominee for its customers who are the
beneficial owners of the units or another organization designated by such bank
or institution.  ILA Class B and Class C Units generally are only issued upon
exchange from Class B or Class C Shares, respectively, of other Series of the
Goldman Sachs mutual funds.  ILA Units and FST Shares may be purchased for
accounts held in the name of an investor or institution that is not compensated
by the Trust for services provided to the institution's investors.  ILA
Administration Units and FST Administration Shares may be purchased for accounts
held in the name of an investor or an institution that provides certain account
administration services to its customers, including maintenance of account
records and processing orders to purchase, redeem and exchange ILA
Administration Units or FST Administration Shares.  ILA Administration Units of
each ILA Portfolio bear the cost of administration fees at the annual rate of up
to .15 of 1% of the average daily net assets of such Units.  FST Administration
Shares of a Financial Square Fund bear the cost of administration fees at the
annual rate of up to .25 of 1% of the average daily net assets of such Shares.
ILA Service Units and FST Service Shares may be purchased for accounts held in
the name of an institution that provides certain account administration and
unitholder liaison services to its customers, including maintenance of account
records, processing orders to purchase, redeem and exchange ILA Service Units or
FST Service Shares, responding to customer inquiries and assisting customers
with investment procedures.  ILA Service Units bear the cost of service fees at
the annual 

                                     -75-
<PAGE>
 
rate of up to .40 of 1% of the average daily net assets of such Units. FST
Service Shares of a Financial Square Fund bear the cost of service fees at the
annual rate of up to .50 of 1% of the average daily net assets of such Shares.
FST Preferred Shares may be purchased for accounts held in the name of an
institution that provides certain account administration services to its
customers, including acting directly or through an agent, as the sole
shareholder of record, maintaining account records of its customers and
processing orders to purchase, redeem and exchange FST Preferred Shares. FST
Preferred Shares of a Financial Square Fund bear the cost of preferred
administration fees at an annual rate of up to 0.10% of the average daily net
assets of such shares. ILA Class B Units of the Prime Obligations Portfolio are
sold subject to a contingent deferred sales charge of up to 5.0%, and ILA Class
C Units are sold subject to a contingent deferred sales charge of 1.0% if
redeemed within 12 months of purchase. ILA Class B and Class C Units are sold
primarily through brokers and dealers who are members of the National
Association of Securities Dealers Inc. and certain other financial services
firms that have sales arrangements with Goldman Sachs. ILA Class B and Class C
Units bear the cost of distribution (Rule 12b-1) fees at the aggregate rate of
up to 0.75% of the average daily net assets attributable to ILA Class B and
Class C Units, respectively. ILA Class B and Class C Units also bear the cost of
service fees at an annual rate of up to 0.25% of the average daily net assets of
the Prime Obligations Portfolio attributable to ILA Class B and Class C Units.
Cash Management Shares may be purchased for accounts held in the name of an
institution that provides certain account administration and shareholder liaison
services to its customers, including maintenance of account records, processing
orders to purchase, redeem and exchange Cash Management Shares, responding to
customer inquiries and assisting customers with investment procedures. Cash
Management Shares bear the cost of service fees at the annual rate of up to
0.50% of the average daily net assets of such shares. Cash Management Shares
also bear the cost of distribution (Rule 12b-1) fees at an annual rate of 0.50%
of the average daily net assets attributable to Cash Management Shares. In
addition, each class of ILA units bears its own transfer agency expenses.

  It is possible that an institution or its affiliates may offer different
classes of units to its customers and thus receive different compensation with
respect to different classes of units of the same Series.  In the event a Series
is distributed by salespersons or any other persons, they may receive different
compensation with respect to different classes of units of the Series.  ILA
Administration Units, ILA Service Units, ILA Class B Units, ILA Class C Units,
Cash Management Shares, FST Administration Shares, FST Preferred Shares and FST
Service Shares each have certain exclusive voting rights on matters relating to
their respective plans.  Units of each class may be exchanged only for Units of
the same class in another ILA Portfolio or, in the case of the Prime Obligations
Portfolio, shares of the corresponding class of certain other mutual funds
sponsored by Goldman Sachs.  Except as described above, the ten classes of units
are identical.  Certain aspects of the Units may be altered, after advance
notice to unitholders, if it is deemed necessary in order to satisfy certain tax
regulatory requirements.

  Rule 18f-2 under the Act provides that any matter required to be submitted by
the provisions of the Act or applicable state law, or otherwise, to the holders
of the outstanding voting securities of an investment company such as the Trust
shall not be deemed to have been effectively acted upon unless approved by the
holders of a majority of the outstanding units of each class or series affected
by such matter.  Rule 18f-2 further provides that a class or series shall be
deemed to be affected by a matter unless the interests of each class or series
in the matter are substantially identical or the matter does not affect any
interest of such class or series.  

                                     -76-

However, Rule 18f-2 exempts the selection of independent public accountants, the
approval of principal distribution contracts and the election of directors from
the separate voting requirements of Rule 18f-2.

  When issued units are fully paid and non-assessable.  In the event of
liquidation, unitholders are entitled to share pro rata in the net assets of the
applicable class of the relevant Series available for distribution to such
unitholders.  All units entitle their holders to one vote per unit, are freely
transferable and have no preemptive subscription or conversion rights.

  The Trust is not required to hold annual meetings of shareholders and does not
intend to hold such meetings.  In the event that a meeting of shareholders is
held, each share of the Trust will be entitled, as determined by the Trustees
without the vote or consent of shareholders, either to one vote for each share
or to one vote for each dollar of net asset value represented by such shares on
all matters presented to unitholders including the election of Trustees (this
method of voting being referred to as "dollar based voting").  However, to the
extent required by the Act or otherwise determined by the Trustees, series and
classes of the Trust will vote separately from each other.  Shareholders of the
Trust do not have cumulative voting rights in the election of Trustees.
Meetings of shareholders of the Trust, or any series or class thereof, may be
called by the Trustees, certain officers or upon the written request of holders
of 10% or more of the shares entitled to vote at such meetings.  The
shareholders of the Trust will have voting rights only with respect to the
limited number of matters specified in the Declaration of Trust and such other
matters as the Trustees may determine or may be required by law.

  The Declaration of Trust provides for indemnification of Trustees, officers
and agents of the Trust unless the recipient is adjudicated (i) to be liable by
reason of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of such person's office or (ii) not to
have acted in good faith in the reasonable belief that such person's actions
were in the best interest of the Trust.  The Declaration of Trust provides that,
if any shareholder or former shareholder of any series is held personally liable
solely by reason of being or having been a shareholder and not because of the
shareholder's acts or omissions or for some other reason, the shareholder or
former shareholder (or heirs, executors, administrators, legal representatives
or general successors) shall be held harmless from and indemnified against all
loss and expense arising from such liability.  The Trust acting on behalf of any
affected series, must, upon request by such shareholder, assume the defense of
any claim made against such shareholder for any act or obligation of the series
and satisfy any judgment thereon from the assets of the series.

  The Declaration of Trust permits the termination of the Trust or of any series
or class of the Trust (i) by a majority of the affected shareholders at a
meeting of shareholders of the Trust, series or class; or (ii) by a majority of
the Trustees without shareholder approval if the Trustees determine that such
action is in the best interest of the Trust or its shareholders.  The factors
and events that the Trustees may take into account in making such determination
include (i) the inability of the Trust or any successor series or class to
maintain its assets at an appropriate size; (ii) changes in laws or regulations
governing the Trust, or any series or class thereof, or affecting assets of the
type in which it invests; or (iii) economic developments or trends having a
significant adverse impact on their business or operations.

                                     -77-
<PAGE>
 
  The Declaration of Trust authorizes the Trustees without shareholder approval
to cause the Trust, or any series thereof, to merge or consolidate with any
corporation, association, trust or other organization or sell or exchange all or
substantially all of the property belonging to the Trust or any series thereof.
In addition, the Trustees, without shareholder approval, may adopt a "master-
feeder" structure by investing all or a portion of the assets of a series of the
Trust in the securities of another open-end investment company.

  The Declaration of Trust permits the Trustees to amend the Declaration of
Trust without a shareholder vote.  However, shareholders of the Trust have the
right to vote on any amendment (i) that would affect the voting rights of
shareholders, (ii) that is required by law to be approved by shareholders; (iii)
that would amend the voting provisions of the Declaration of Trust; or (iv) that
the Trustees determine to submit to shareholders.

  The Trustees may appoint separate Trustees with respect to one or more series
or classes of the Trust's shares (the "Series Trustees").  To the extent
provided by the Trustees in the appointment of Series Trustees, Series Trustees
(a) may, but are not required to, serve as Trustees of the Trust or any other
series or class of the Trust; (b) may have, to the exclusion of any other
Trustee of the Trust, all the powers and authorities of Trustees under the
Declaration of Trust with respect to any other series or class; and/or (c) may
have no power or authority with respect to any other series or class.  The
Trustees are not currently considering the appointment of Series Trustees for
the Trust.

Unitholder and Trustee Liability

  Under Delaware law, the unitholders of the Series are not generally subject to
liability for the debts or obligations of the Trust. Similarly, Delaware law
provides that a series of the Trust will not be liable for the debts or
obligations of any other series of the Trust. However, no similar statutory or
other authority limiting business trust unitholder liability exists in many
other states. As a result, to the extent that a Delaware business trust or a
unitholder is subject to the jurisdiction of courts of such other states, the
courts may not apply Delaware law and may thereby subject the Delaware business
trust unitholders to liability. To guard against this risk, the Declaration of
Trust contains express disclaimer of unitholder liability for acts or
obligations of a Series.  Notice of such disclaimer will normally be given in
each agreement, obligation or instrument entered into or executed by a Portfolio
or the Trustees. The Declaration of Trust provides for indemnification by the
relevant Series for all loss suffered by a unitholder as a result of an
obligation of the Series. The Declaration of Trust also provides that a Series
shall, upon request, assume the defense of any claim made against any unitholder
for any act or obligation of the Series and satisfy any judgment thereon. In
view of the above, the risk of personal liability of unitholders is remote.

                                     -80-
<PAGE>
 
  In addition to the requirements set forth under Delaware Law, the Declaration
of Trust provides that unitholders may bring a derivative action on behalf of
the Trust only if the following conditions are met: (a) unitholders eligible to
bring such derivative action under Delaware law who hold at least 10% of the
outstanding units of the Trust, or 10% of the outstanding units of the series or
class to which such action relates, must join in the request for the Trustees to
commence such action; and (b) the Trustees must be afforded a reasonable amount
of time to consider such unitholder request and to investigate the basis of such
claim. The Trustees will be entitled to retain counsel or other advisers in
considering the merits of the request and may require an undertaking by the
Unitholders making such request to reimburse the Trust for the expense of any
such advisers in the event that the Trustees determine not to bring such action.

  The Declaration of Trust further provides that the Trustees will not be liable
for errors of judgment or mistakes of fact or law, but nothing in the
Declaration of Trust protects a Trustee against liability to which he or she
would otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties involved in the conduct of his
or her office.

                           CUSTODIAN AND SUBCUSTODIAN

  State Street Bank and Trust Company ("State Street") has been retained to act
as custodian of the Series' assets.  In that capacity, State Street maintains
the accounting records and calculates the daily net asset value per unit of the
Series. Its mailing address is P.O. Box 1713, Boston, MA 02105.  State Street
has appointed The Northern Trust Company, 50 South LaSalle Street, Chicago,
Illinois 60675 as subcustodian to hold cash and certain securities purchased by
the Trust.


                            INDEPENDENT ACCOUNTANTS

  Arthur Andersen LLP, independent public accountants, 225 Franklin Street,

internal control and related matters.

                               OTHER INFORMATION


    
  The Adviser, Distributor and/or their affiliates may pay, out of their own
assets, compensation to Authorized Dealers, Service Organizations and financial
intermediaries ("Intermediaries") in connection with the sale, distribution
and/or servicing of shares of the Series. These payments ("Additional Payments")
would be in addition to the payments by the Series described in the Series'
Prospectuses and this Additional Statement for distribution and shareholder
servicing and processing. These Additional Payments may take the form of "due
diligence" payments for an institution's examination of the Series and payments
for providing extra employee training and information relating to the Series;
"listing" fees for the placement of the Series on a dealer's list of mutual
funds available for purchase by its customers; "finders" or "referral" fees for
directing investors to the Series; "marketing support" fees for providing
assistance in promoting the sale of the Series' shares; and payments for the
sale of shares and/or the maintenance of share balances. In addition, the
Adviser, Distributor and/or their affiliates may make Additional Payments for
subaccounting, administrative and/or shareholder processing services that are in
addition to any shareholder servicing and processing fees paid by the Series.
The Additional Payments made by the Adviser, Distributor and their affiliates
may be a fixed dollar amount, may be based on the number of customer accounts
maintained by an Intermediary, or may be based on a percentage of the value of
shares sold to, or held by, customers of the Intermediary involved, and may be
different for different Intermediaries. Furthermore, the Adviser, Distributor
and/or their affiliates may contribute to various non-cash and cash incentive
arrangements to promote the sale of shares, as well as sponsor various
educational programs, sales contests and/or promotions. The Adviser, Distributor
and their affiliates may also pay for the travel expenses, meals, lodging and
entertainment of Intermediaries and their salespersons and guests in connection
with educational, sales and promotional programs, subject to applicable NASD
regulations. The Distributor currently expects that such additional bonuses or
incentives will not exceed 0.50% of the amount of any sales.     

  The Prospectuses and this Additional Statement do not contain all the
information included in the Registration Statement filed with the SEC under the
1933 Act with respect to the securities offered by the Prospectuses.  Certain
portions of the Registration Statement have been omitted from the Prospectuses
and this Additional Statement pursuant to the rules and regulations of the SEC.
The Registration Statement including the exhibits filed  therewith may be
examined at the office of the SEC in Washington, D.C.

  Statements contained in the Prospectuses or in this Additional Statement as to
the contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which the
Prospectuses and this Additional Statement form a part, each such statement
being qualified in all respects by such reference.

                              ADMINISTRATION PLANS

     (ILA Administration, FST Administration and FST Preferred Shares Only)

  The Trust, on behalf of each ILA Portfolio and Financial Square Fund, has
adopted an administration plan with respect to the ILA Administration Units (the
"ILA Administration Plan"), with respect to the FST Administration Shares (the
"FST Administration Plan") and FST Preferred Shares (the "FST Preferred Plan,"
together with the ILA Administration Plan and the FST Administration Plan, the
"Administration Plans") which authorize the ILA Portfolios and Financial Square
Funds to compensate Service Organizations for providing certain account
administration services to their customers who are beneficial owners of such
units.  Pursuant to the Administration Plans, the Trust, on behalf of each
Series, enters into agreements with Service Organizations which purchase ILA
Administration Units, FST Administration Shares or FST Preferred Shares on
behalf of their customers ("Service Agreements").  Under such Service
Agreements, the Service Organizations may:  (a) act, directly or through an
agent, as the sole unitholder of record and nominee for all customers, (b)
maintain account records for each customer who beneficially owns ILA
Administration Units, FST Administration Shares or FST Preferred Shares, (c)
answer questions and handle correspondence from customers regarding their
accounts, (d) process customer orders to purchase, redeem and exchange ILA
Administration Units, FST Administration Shares or FST Preferred Shares, and
handle the transmission of funds representing the customers' purchase price or
redemption proceeds, and (e) issue confirmations for transactions in units by
customers.  As compensation for such services, the Trust on behalf of each ILA
Portfolio and Financial Square Fund pays each Service Organization an
administration fee in an amount up to .15% (on an annualized basis) of the
average daily net assets of the ILA Administration Units of each ILA Portfolio,
..25% (on an annualized basis) of the average daily net assets of the FST
Administration Shares and .10% (on an annualized basis) of the average daily net
assets of the FST Preferred Shares of each Financial Square Fund, attributable
to or held in the name of such Service Organization for its customers.

  For the fiscal years ended December 31, 1998, December 31, 1997 and December
31, 1996 the amount of the administration fees paid by each ILA Portfolio under
its ILA Administration Plan to Service Organizations was as follows:

  Conflict of interest restrictions (including the Employee Retirement Income
Security Act of 1974) may apply to a Service Organization's receipt of
compensation paid by the Trust in connection with the investment of fiduciary
funds in ILA Administration Units, FST Administration Shares and FST Preferred
Shares.  Service Organizations, including banks regulated by the Comptroller of
the Currency, the Federal Reserve Board or the Federal Deposit Insurance
Corporation, and investment advisers and other money managers subject to the
jurisdiction of the Securities and Exchange Commission, the Department of Labor
or State Securities Commissions, are urged to consult legal advisers before
investing fiduciary assets in ILA Administration Units, FST Administration
Shares or FST Preferred Shares.  In addition, under some state securities laws,
banks and other financial institutions purchasing ILA Administration Units, FST
Administration Shares or FST Preferred Shares on behalf of their customers may
be required to register as dealers.

  The Trustees of the Trust, including a majority of the Trustees who are not
interested persons of the Trust and who have no direct or indirect financial
interest in the operation of the Administration Plans or the related Service
Agreements, most recently voted to approve the Administration Plans and Service
Agreements at a meeting called for the purpose of voting on such Administration
Plans and Service Agreements on _________, 1999.  The Administration Plans and
Service Agreements will remain in effect until May 1, 2000 and continue in
effect thereafter only if such continuance is specifically approved annually by
a vote of the Trustees in the manner described above.

  An Administration Plan may not be amended to increase materially the amount to
be spent for the services described therein without approval of the ILA
Administration, FST Administration or FST Preferred shareholders of the affected
Series, and all material amendments of the Administration Plan must also be
approved by the Trustees in the manner described above.  An Administration Plan
may be terminated at any time by a majority of the Trustees as described above
or by vote of a majority of the outstanding ILA Administration Units, FST
Administration Shares or FST Preferred Shares of the affected Series.  The
Service Agreements may be terminated at any time, without payment of any
penalty, by vote of a majority of the Trustees as described above or by a vote
of a majority of the outstanding ILA Administration Units, FST Administration
Shares or FST Preferred Shares of the affected Series on not more than sixty
(60) days' written notice to any other party to the Service Agreements.  The
Service Agreements shall terminate automatically if assigned.  So long as the
Administration Plans are in effect, the selection and nomination of those
Trustees who are not interested persons shall be committed to the discretion of
the Trust's Nominating Committee, which consists of all of the non-interested
members of the Board of Trustees.  The Trustees have determined that, in their
judgment, there is a reasonable likelihood that the Administration Plans will
benefit the Series and holders of ILA Administration Units, FST Administration
Shares and FST Preferred Shares of such Series.

                                 SERVICE PLANS

    (ILA Service Units, Cash Management Shares and FST Service Shares Only)

  The Trust has adopted a service plan on behalf of each ILA Portfolio with
respect to the ILA Service Units (the "ILA Service Plan"), on behalf of the ILA
Prime Obligations Portfolio, ILA Money Market Portfolio, ILA Government
Portfolio, ILA Tax-Exempt Diversified Portfolio and ILA Tax-Exempt New York
Portfolio with respect to the Cash Management Shares (the "Cash Management
Shares Service Plan") and on behalf of each Financial Square Fund with respect
to the FST Service Shares (the "FST Service Plan" and together with the ILA
Service Plan and the Cash Management Shares Service Plan, the "Service Plans")
which authorize the Series to compensate Service Organizations for providing
certain account administration and personal account maintenance services to
their customers who are or may become beneficial owners of such units.  Pursuant
to the Service Plans, the Trust, on behalf of each ILA Portfolio or Financial
Square Fund, enters into agreements with Service Organizations which purchase
ILA Service Units, Cash Management Shares or FST Service Shares on behalf of
their customers ("Service Agreements").  Under such Service Agreements the
Service Organizations may: (a) act, directly or through an agent, as the sole
unitholder of record and nominee for all customers; (b) maintain account records
for each customer who beneficially owns ILA Service Units, Cash Management
Shares or FST Service Shares; (c) answer questions and handle correspondence
from customers regarding their accounts; (d) process customer orders to
purchase, redeem and exchange ILA Service Units, Cash Management Shares or FST
Service Shares, and handle the transmission of funds representing the customers'
purchase price or redemption proceeds; (e) issue confirmations for transactions
in units by customers; (f) provide facilities to answer questions from
prospective and existing investors about ILA Service Units, Cash Management
Shares or FST Service Shares; (g) receive and answer investor correspondence,
including requests for prospectuses and statements of additional information;
(h) display and make prospectuses available on the Service Organization's
premises; (i) assist customers in completing application forms, selecting
dividend and other account options and opening custody accounts with the Service
Organization; (j) act as liaison between customers and the Trust, including
obtaining information from the Trust, working with the Trust to correct errors
and resolve problems and providing statistical and other information to the
Trust; and (k) with respect to the Cash Management Shares Service Plan:  (i)
provide services to customers intended to facilitate or improve their
understanding of the benefits and risks of an ILA Portfolio, (ii) facilitate the
inclusion of an ILA Portfolio in investment, retirement, asset allocation, cash
management or sweep accounts or similar products or services offered to
customers by or through Service Organizations, (iii) facilitate electronic or
computer trading and/or processing in an ILA Portfolio or providing electronic,
computer or other database information regarding an ILA Portfolio to customers,
and (iv) develop, maintain and support systems necessary to support Cash
Management Shares.  As compensation for such services, (a) the Trust on behalf
of each ILA Portfolio pays each Service Organization a service fee in an amount
up to .40% (on an annualized basis) of the average daily net assets of the ILA
Service Units of each ILA Portfolio attributable to or held in the name of such
Service Organization for its customers; provided, however, that the fee paid for
personal and account maintenance services shall not exceed .25% of such average
daily net assets; (b) the Trust on behalf of each ILA Portfolio pays each
Service Organization a service fee in an amount up to .50% (on an annual basis)
of the average daily net assets of the Cash Management Shares of each ILA
Portfolio attributable to or held in the name 

                                    - 86 -
<PAGE>
 
of such Service Organization for its customers; provided, however, that the fee
paid for personal and account maintenance services shall not exceed .25% of such
average daily net assets; and (c) the Trust, on behalf of each Financial Square
Fund, pays each Service Organization a service fee in an amount up to .50% (on
an annualized basis) of the average daily net assets of the FST Service Shares
of each Financial Square Fund attributable to or held in the name of such
Service Organization for its customers; provided, however, that the fee paid for
personal and account maintenance services shall not exceed .25% of such average
daily net assets.

  As stated in the Prospectuses, the Trust may authorize Service Organizations
and other institutions that provide recordkeeping, reporting and processing
services to their customers to accept on the Trust's behalf purchase, redemption
and exchange orders placed by or on behalf of their customers and, if approved
by the Trust, to designate other intermediaries to accept such orders.  These
institutions may receive payments from the Trust or Goldman Sachs for their
services.  In some, but not all, cases these payments will be pursuant to an
Administration, Distribution or Service Plan described in the Prospectuses and
the following sections.  Certain Service Organizations or institutions may enter
into sub-transfer agency agreements with the Trust or Goldman Sachs with respect
to their services.

  For the fiscal years ended December 31, 1998, December 31, 1997 and  December
31, 1996 the amount of the service fees paid by each ILA Portfolio then in
existence to Service Organizations pursuant to the ILA Service Plan was as

[As of December 31, 1998, FS Municipal Fund had not commenced operations.]

  The Trust has adopted each Service Plan pursuant to Rule 12b-1 under the
Investment Company Act in order to avoid any possibility that payments to the
Service Organizations pursuant to the Service Agreements might violate the
Investment Company Act.  Rule 12b-1, which was adopted by the Securities and
Exchange Commission under the Investment Company Act, regulates the
circumstances under which an investment company such as the Trust may bear
expenses associated with the distribution of its securities.  In particular,
such an investment company cannot engage directly or indirectly in financing any
activity which is primarily intended to result in the sale of securities issued
by the company unless it has adopted a plan pursuant to, and complies with the
other requirements of, such Rule.  The Trust believes that fees paid for the
services provided in the Service Plans and described above are not expenses
incurred primarily for effecting the distribution of ILA Service Units, Cash
Management Shares or FST Service Shares.  However, should such payments be
deemed by a court or the Securities and 

                                    - 88 -
<PAGE>
 
Exchange Commission to be distribution expenses, such payments would be duly
authorized by the Service Plans.

  The Glass-Steagall Act prohibits all entities which receive deposits from
engaging to any extent in the business of issuing, underwriting, selling or
distributing securities, although institutions such as national banks are
permitted to purchase and sell securities upon the order and for the account of
their customers.  Should future legislative or administrative action or judicial
or administrative decisions or interpretations prohibit or restrict the
activities of one or more of the Service Organizations in connection with the
Trust, such Service Organizations might be required to alter materially or
discontinue the services performed under their Service Agreements.  If one or
more of the Service Organizations were restricted from effecting purchases or
sales of ILA Service Units, Cash Management Shares or FST Service Shares
automatically pursuant to pre-authorized instructions, for example, effecting
such transactions on a manual basis might affect the size and/or growth of the
Series.  In addition, state securities laws on this issue may differ from the
interpretations of federal law expressed herein and banks and other financial
institutions purchasing ILA Service Units, Cash Management Shares or FST Service
Shares on behalf of their customers may be required to register as dealers
pursuant to state law.  Any such alteration or discontinuance of services could
require the Trustees of the Trust to consider changing the Trust's method of
operations or providing alternative means of offering ILA Service Units, Cash
Management Shares or FST Service Shares to customers of such Service
Organizations, in which case the operation of the Trust, its size and/or its
growth might be significantly altered.  It is not anticipated, however, that any
alteration of the Trust's operations would have any effect on the net asset
value per unit or result in financial losses to any unitholder or shareholder.

  Conflict of interest restrictions (including the Employee Retirement Income
Security Act of 1974) may apply to a Service Organization's receipt of
compensation paid by the Trust in connection with the investment of fiduciary
funds in ILA Service Units, Cash Management Shares or FST Service Shares.
Service Organizations, including banks regulated by the Comptroller of the
Currency, the Federal Reserve Board or the Federal Deposit Insurance
Corporation, and investment advisers and other money managers subject to the
jurisdiction of the Securities and Exchange Commission, the Department of Labor
or State Securities Commissions, are urged to consult legal advisers before
investing fiduciary assets in ILA Service Units, Cash Management Shares or FST
Service Shares.

  The Trustees of the Trust, including a majority of the Trustees who are not
interested persons of the Trust and who have no direct or indirect financial
interest in the operation of the Service Plans or the related Service
Agreements, most recently voted to approve the Service Plans and Service
Agreements at a meeting called for the purpose of voting on such Service Plans
and Service Agreements on ________, 1999.  They will remain in effect until May
1, 2000 and will continue in effect thereafter only if such continuance is
specifically approved annually by a vote of the Trustees in the manner described
above.

  A Service Plan may not be amended to increase materially the amount to be
spent for the services described therein without approval of the ILA Service
Unitholders, Cash Management Shareholders or FST Service Shareholders of the
affected Series, and all material amendments of 

                                    - 89 -
<PAGE>
 
a Plan must also be approved by the Trustees in the manner described above. A
Service Plan may be terminated at any time by a majority of the Board of
Trustees as described above or by vote of a majority of the outstanding ILA
Service Units, Cash Management Shareholders or FST Service Shares of the
affected Series. The Service Agreements may be terminated at any time, without
payment of any penalty, by vote of a majority of the Board of Trustees as
described above or by a vote of a majority of the outstanding ILA Service Units,
Cash Management Shareholders or FST Service Shares of the affected Series on not
more than sixty (60) days' written notice to any other party to the Service
Agreements. The Service Agreements shall terminate automatically if assigned. As
long as the Service Plans are in effect, the selection and nomination of those
Trustees who are not interested persons shall be determined by the discretion of
the Trust's Nominating Committee, which consists of all of the non-interested
members of the Board of Trustees. The Trustees have determined that, in their
judgment, there is a reasonable likelihood that the Service Plans will benefit
the Series and holders of ILA Service Units, Cash Management Shares and FST
Service Shares of such Series. In the Trustees' quarterly review of the Service
Plans and Service Agreements, they will consider their continued appropriateness
and the level of compensation provided therein.


                         DISTRIBUTION AND SERVICE PLANS

  DISTRIBUTION AND SERVICE PLANS.  As described in the Prospectuses, the Trust
has adopted distribution and service plans pursuant to Rule 12b-1 under the
Investment Company Act with respect to ILA Class B and Class C Units on behalf
of the ILA Prime Obligations Portfolio (the "Distribution and Service Plans").
See "Distribution and Service Plans" in the ILA Class B and Class C Units
Prospectus.

  The Distribution and Service Plans were most recently approved on __________,
1999 by a majority vote of the Trustees of the Trust, including a majority of
the non-interested Trustees of the Trust who have no direct or indirect
financial interest in the Distribution and Service Plans, cast in person at a
meeting called for the purpose of approving the Distribution and Service Plans.

  The compensation payable under the Distribution and Service Plans may not
exceed 0.75% per annum of the average daily net assets attributable to ILA Class
B and Class C Units, respectively, of that ILA Portfolio.

     Under the Distribution and Service Plans for ILA Class B and Class C
Shares, Goldman Sachs is also entitled to receive a separate fee for personal
and account maintenance services equal to an annual basis of 0.25% of each
Fund's average daily net assets attributable to ILA Class B or Class C Units.

  The Distribution and Service Plans are compensation plans which provide for
the payment of a specified fee without regard to the expenses actually incurred
by Goldman Sachs.  The distribution fees received by Goldman Sachs under the
Distribution and Service Plans and contingent deferred sales charges on ILA
Class B Units may be sold by Goldman Sachs as distributor to entities which
provide financing for payments to Authorized Dealers in respect of 

                                    - 90 -
<PAGE>
 
sales of ILA Class B Units. Goldman Sachs may also pay up to the entire amount
of its fee under the Class C Distribution and Service Plan to Service
Organizations or other institutions for providing services in connection with
the sale of Class C Units. To the extent such fees are not paid to such dealers,
Goldman Sachs may retain such fee as compensation for its services and expenses
of distributing ILA Class B Units and Class C Units. If such fees exceed Goldman
Sachs' expenses, Goldman Sachs may realize a profit from these arrangements. For
the fiscal years ended December 31, 1998 and December 31, 1997, the amount of
distribution fees paid by the ILA Prime Obligations Portfolio's Class B Shares
to Goldman Sachs was $____ and $4,635, respectively.

     For the fiscal years ended December 31, 1998 and December 31, 1997, the
amount of distribution fees paid by the ILA Prime Obligations Portfolio's Class
C Shares to Goldman Sachs was $____ and $784, respectively.

  Under the Distribution and Service Plans, Goldman Sachs, as distributor of the
Portfolio's ILA Class B Units and Class C Units, will provide to the Board of
Trustees for its review, and the Board will review at least quarterly, a written
report of the services provided and amounts expended by Goldman Sachs under the
Distribution and Service Plans and the purposes for which such services were
performed and expenditures were made.

  The Distribution and Service Plans will remain in effect from year to year,
provided such continuance is approved annually by a majority vote of the
Trustees of the Trust, including a majority of the non-interested Trustees who
have no direct or indirect financial interest in the Distribution and Service
Plans.  The Distribution and Service Plans may not be amended to increase
materially the amount of distribution compensation described therein as to a
particular Portfolio without approval of a majority of the outstanding Class B
or Class C Unitholders, of the affected Portfolio and Unit class.  All material
amendments to the Distribution and Service Plans must also be approved by the
Trustees of the Trust in the manner described above.  The Distribution and
Service Plans may be terminated at any time without payment of any penalty by a
vote of the majority of the non-interested Trustees or by vote of a majority of
the Class B or Class C Units, of the applicable Portfolio.  If the Distribution

payments to Goldman Sachs and Goldman Sachs would be unable to recover the
amount of any of its unreimbursed distribution expenditures.  So long as the
Distribution and Service Plans are in effect, the selection and nomination of
non-interested Trustees will be committed to the discretion of the non-
interested Trustees.  The Trustees have determined that in their judgment there
is a reasonable likelihood that the Distribution and Service Plans will benefit
the applicable Portfolios and their respective Unitholders.

     For the fiscal year ended December 31, 1998 and December 31, 1997, the
amount of services fees paid by the ILA Prime Obligations Portfolio's Class B
Shares to Goldman Sachs was $_____ and $1,545, respectively.

  For the fiscal years ended December 31, 1998 and December 31, 1997, the amount
of service fees paid by the ILA Prime Obligations Portfolio's Class C Shares to
Goldman Sachs was $_____ and $261, respectively.

  DISTRIBUTION PLAN.  As described in the Prospectus, the Trust has adopted a
distribution plan pursuant to Rule 12b-1 under the Investment Company Act with
respect to Cash Management Shares on behalf of the ILA Prime Obligations
Portfolio, ILA Money Market Portfolio, ILA Government Portfolio, ILA Tax-Exempt
Diversified Portfolio, ILA Tax-Exempt California Portfolio and ILA Tax-Exempt
New York Portfolio (the "Cash Management Shares Distribution Plan").  See
"Distribution Plan" in the Cash Management Shares' Prospectus.

  The Distribution Plan was most recently approved on ________, 1999 on behalf
of the Trust by a majority vote of the Trust's Board of Trustees, including a
majority of the Trustees who are not interested persons of the Trust and have no
direct or indirect financial interest in the Distribution Plan, cast in person
at a meeting called for the purpose of approving the Distribution Plan.

  The compensation payable under the Cash Management Shares Distribution Plan
with respect to the ILA Prime Obligations Portfolio, ILA Money Market Portfolio,
ILA Government Portfolio, ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt
California Portfolio and ILA Tax-Exempt New York Portfolio may not exceed 0.50%
per annum of the average daily net assets attributable to Cash Management Shares
of such ILA Portfolio.  [Currently, Goldman Sachs is limiting the fee payable by
ILA Prime Obligations Portfolio, ILA Money Market Portfolio, ILA Government
Portfolio, ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California
Portfolio and ILA Tax-Exempt New York Portfolio to 0.07% of average daily net
assets attributable to Cash Management Shares.]  Goldman Sachs may modify or
discontinue such waivers and limitation in the future at its discretion.

     Goldman Sachs may pay up to the entire amount of its fee under the
Distribution Plan to Service Organizations or other institutions for providing
services in connection with the sale of Cash Management Shares.  To the extent
such fees are not paid to such dealers, Goldman Sachs may retain such fee as
compensation for its services and expenses of distributing Cash Management
Shares. If such fee exceeds its expenses, Goldman Sachs may realize a profit
from these arrangements.

  The Distribution Plan is a compensation plan which provides for the payment of
a specified distribution fee without regard to the distribution expenses
actually incurred by Goldman Sachs.  If the Distribution Plan was terminated by
the Trust's Board of Trustees and no successor plan were adopted, the ILA Prime
Obligations Portfolio, ILA Money Market Portfolio, ILA Government Portfolio, ILA
Tax-Exempt Diversified Portfolio, ILA Tax-Exempt California Portfolio and ILA
Tax-Exempt New York Portfolio would cease to make distribution payments to
Goldman Sachs and Goldman Sachs would be unable to recover the amount of any of
its unreimbursed distribution expenditures.  However, Goldman Sachs does not
intend to make expenditures for which it may be compensated under the Cash
Management Shares Distribution Plan at a rate that materially exceeds the rate
of compensation received under the Plan.

  Under the Cash Management Distribution Plan, Goldman Sachs, as distributor of
the Portfolio's Cash Management Shares, will provide to the Board of Trustees
for its review, and the Board will review at least quarterly, a written report
of the services provided and amounts 

                                    - 92 -
<PAGE>
 
expended by Goldman Sachs under the Cash Management Distribution Plan and the
purposes for which such services were performed and expenditures were made.

  The Distribution Plan will remain in effect from year to year, provided such
continuance is approved annually by a majority vote of the Board of Trustees,
including a majority of the non-interested Trustees.  The Distribution Plan may
not be amended to increase materially the amount to be spent for the services
described therein as to a particular Portfolio without approval of a majority of
the outstanding Cash Management Unitholders, as applicable, of that Portfolio.
All material amendments to the Distribution Plan must also be approved by the
Board of Trustees of the Trust in the manner described above.  The Distribution
Plans may be terminated at any time without payment of any penalty by a vote of
the majority of the non-interested Trustees or by vote of a majority of the Cash
Management Units, as applicable, of the applicable Portfolio.  So long as the
Distribution Plan is in effect, the selection and nomination of non-interested
Trustees shall be committed to the discretion of the non-interested Trustees.
The Trustees have determined that in their judgment there is a reasonable
likelihood that the Distribution Plan will benefit the applicable Portfolios and
their respective Unitholders.

  For the fiscal year ended December 31, 1998, the amount of distribution fees
paid by the ILA Prime Obligations Portfolio, ILA Money Market Portfolio, ILA
Government Portfolio, ILA Tax-Exempt Diversified Portfolio, ILA Tax-Exempt
California Portfolio and ILA Tax-Exempt New York Portfolio to Goldman Sachs
pursuant to the Cash Management Shares Distribution Plan was $______, $______,
$______, $______, $________ and $_______, respectively.

Dear Shareholders:
 
  We welcome this opportunity to provide you with a summary of the trends and
key events that affected the economy and the Goldman Sachs Institutional
Liquid Assets (ILA) Portfolios in 1998. It was another strong year for the
funds, during which all of the portfolios outperformed or performed in line
with their respective IBC Financial Data, Inc. averages. Net assets in the ILA
Portfolios totaled $10.5 billion as of December 31, 1998.
 
The Economy In Review
  Despite a slight tempering due to soft employment numbers, the U.S. economy
continued to see strong growth for most of 1998. This growth, combined with
continued uncertainty about the impact of Asian instability on the U.S.
economy, kept the Federal Reserve in a wait-and-see mode for the first nine
months of the year.
  On September 29th, in the wake of increasing global market turmoil, the
Federal Reserve Board cut the Federal Funds target rate by 25 basis points, to
5.25%. As increasing illiquidity concerns in the market became more severe,
the Fed followed up with two more surprise rate cuts, easing the target rate
and the discount rate by another 50 basis points.
  The Fed's moves were a strong signal that the monetary authorities were
prepared to do whatever was necessary to provide liquidity and to support the
economy against the forces that had the potential of a substantial economic
slowdown in 1999.
  At period end, while consumer spending remained strong, the manufacturing
side of the economy appeared to weaken because of a trade drag and a slowdown
in capital spending. However, based on signs of non-inflationary growth in the
areas of consumer spending, new home sales and strong third quarter gross
domestic product (GDP), the general consensus is that any further easing by
the Fed will come later, rather than sooner.
 
Credit Year 1998: A Year of Crisis with a Hopeful Ending
  Domestic credit quality continued its strong positive trend for the first
six months of 1998. Mergers and acquisitions were at an all time high. U.S.
banks remained strong, well capitalized and provisioned, with diversified
operations. The stock market continued its climb and American consumers were
spending more than they were earning. The shocks of the Russian default in
August and the near collapse of Long Term Capital Management (LTCM) caused
severe liquidity problems and a difficult trading environment, as well as a
major sell-off in the stock market. Calm was restored by the rescue of LTCM
and the Fed's lowering of interest rates three times in seven weeks. A newly
risk adverse investor moved funds to safer, more liquid credits. The
enthusiasm for globalization was temporarily curbed, as domestic production
was suppressed in response to the Asian crisis and corporate profit gains for
the year were generally mixed.
  The international credit environment in 1998 saw the Asian situation explode
into a full-blown global crisis that adversely affected markets around the
world. The default and devaluation of Russia in August came after an already
painful several months of recession and restructuring in Asia. This pain was
exacerbated by Japan's continued slow economic deterioration, which cast a
shadow over the entire region. The unprecedented market volatility that
followed Russia's default took months to dissipate, and only after a more
committed response by the U.S. government to the crisis. By the end of the
year, however, trends were much more positive. The reforming Asian economies
showed notable progress, with signs of a return to economic growth in 1999.
More significant, however, was the successful launch of the euro. Ongoing
policy convergence and political resolution served to create the world's first
regional currency with nary a ripple in the markets. In fact, with the U.S.
economy seemingly impervious to difficulties elsewhere, global markets quickly
rebounded to close the year on a decidedly positive note.

- ---------------------------------------  ---------------------------------------
  Although the U.S. economy remains favorable, the challenges of global
volatility continue to concern us. The Goldman Sachs Credit Department, with
analysts based in London, Tokyo, Frankfurt and New York, as well as extensive
technological assets and credit expertise, will continue to anticipate and
monitor global developments and apply its conservative credit standards to the
money market portfolios.
 
Strategy
  Taxable--For most of the period, a "flight to quality" resulting from the
ongoing Asian economic crisis rendered the short end of the yield curve
expensive. In view of this, the Portfolios maintained a neutral stance by
buying on market dips and "aging in" when levels got expensive. However, we
extended the weighted average maturity (WAM) ranges from neutral to slightly
long as the Fed began its series of easings in late September in response to
market liquidity. We continued to maintain a barbell structure by holding
significant liquidity in anticipation of year-end outflows, and targeted longer
dated maturities to enhance performance in a declining rate environment.
  Tax-Exempt--Early in the period, given the fact that we no longer foresaw a
near-term Fed easing and in preparation for the seasonally short supply of
municipal issuance in January, we increased the portfolio's WAMs to the 40- to
50-day range. This decision helped keep the portfolios' yields competitive
during this period of high cash inflows and high demand for municipal
securities. In March, we shortened the WAMs of the portfolios to the 30- to 35-
day range, seeking to build liquidity as the April 15th tax deadline
approached. This move helped us to fund tax-time redemptions. In August, when
seasonal issuance was strong and there was less demand in the tax-exempt market
in contrast to the "flight to quality" in the Treasury market, we extended the
portfolios' WAMs to the 40-day range.
  At period end, after a brief period during which the portfolios' WAMs were
brought into a neutral range, we extended the WAMs in anticipation of
technically driven lower yields (due to inflows from the reinvestment of
maturity proceeds, coupled with a seasonal scarcity of issuance).

*ILA offers four separate classes of units/shares (Institutional,
Administration, Service and Cash Management), each of which is subject to
different fees and expenses that affect performance and entitle
unit/shareholders to different services. The Administration and Service units
offer financial institutions the opportunity to receive a fee for providing
administrative support services. The Administration units pay 0.15% plus 0.10%
from the adviser for a total of 0.25%. The Service units pay 0.40% plus 0.10%
from the adviser for a total of 0.50%. The Cash Management shares pay 0.50%
plus 0.30% from the adviser for a total of up to 0.80%. Furthermore, in
addition to these classes, Prime Obligations offers Class B and Class C units,
which may be subject to contingent deferred sales charges. More complete
information, including management fees and expenses, is included in the ILA
Portfolios' prospectus or may be obtained by calling Goldman Sachs Funds at

Outlook and Strategies for 1999
  With the financing pressure of year-end behind institutional investors, we
are looking to extend the portfolios' weighted average maturities somewhat as
we see opportunities on the yield curve. While there are a

variety of opinions as to when the Fed will move, based on current signs of
non-inflationary growth in areas of consumer spending, new home sales and
fourth quarter GDP, most anticipate that easing will come later than sooner.
Goldman Sachs economists' 1999 outlook anticipates a 50 basis point cumulative
ease in the second half of the year.
  In closing, we thank you for your support and for making 1998 a year of
record assets for the ILA money market portfolios. As in the past, we will
continue to look for additional ways to improve our services, while seeking to
provide you with competitive performance. We welcome your suggestions and
questions, and look forward to another strong year in 1999.

Notes to Financial Statements
December 31, 1998
- ---------------------------------------  ---------------------------------------
1. Organization
The Goldman Sachs Trust (the "Trust") is a Delaware business trust registered
under the Investment Company Act of 1940 (as amended) as an open-end management
investment company. The Trust includes the Goldman Sachs--Institutional Liquid
Assets Portfolios, collectively "ILA". ILA consists of nine portfolios: Prime
Obligations, Money Market, Government, Treasury Obligations, Treasury
Instruments, Federal, Tax-Exempt Diversified, Tax-Exempt California and Tax-
Exempt New York. All of the portfolios are diversified except for the Tax-
Exempt California and Tax-Exempt New York Portfolios. ILA offers the following
classes:

The investment objective of the portfolios is to maximize current income to the
extent consistent with the preservation of capital and maintenance of
liquidity. The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New
York Portfolios also seek to provide shareholders with a high level of income
exempt from federal income tax. In addition, the Tax-Exempt California and Tax-
Exempt New York Portfolios seek to provide shareholders with income exempt from
California state and New York state and city personal income taxes,
respectively.
 
2. Significant Accounting Policies
The following is a summary of significant accounting policies consistently
followed by ILA. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that may affect the reported amounts.
 
A. Investment Valuation--
ILA uses the amortized-cost method for valuing portfolio securities, which
approximates market value. Under this method, all investments purchased at a
discount or premium are valued by amortizing the difference between the
original purchase price and maturity value of the issue over the period to
maturity.
 
B. Interest Income--
Interest income is determined on the basis of interest accrued, premium
amortized and discount earned.
 
C. Federal Taxes--
It is each portfolio's policy to comply with the requirements of the Internal
Revenue Code applicable to regulated investment companies and to distribute
each year substantially all investment company taxable and tax-exempt income to
its unitholders. Accordingly, no federal tax provisions are required.
 The characterization of distributions to unit/shareholders for financial
reporting purposes is determined in accordance with federal income tax rules.
Therefore, the source of the portfolios' distributions may be shown in the
accompanying financial statements as either from or in excess of net investment
income or net realized gain on investment transactions, or from paid-in
capital, depending on the type of book/tax differences that may exist.
 At December 31, 1998 (tax year end), the following portfolios had capital loss
carryforwards for U.S. Federal tax purposes of approximately:

<PAGE>
 
- --------------------------------------------------------------------------------
- ---------------------------------------  ---------------------------------------
2. Significant Accounting Policies (continued)
 These amounts are available to be carried forward to offset future capital
gains to the extent permitted by applicable laws or regulations.
 
D. Expenses--
Expenses incurred by ILA which do not specifically relate to an individual
portfolio of ILA are generally allocated to the portfolios based on the nature
of the expense.
 Unitholders of ILA Administration, ILA Service, ILA B, ILA C and Cash
Management share classes bear all expenses and fees paid to service and
distribution organizations for their services with respect to such classes as
well as other expenses (subject to expense limitations) which are directly
attributable to such classes. Effective September 1, 1998, each class of
units/shares of the Portfolios now separately bears its respective class-
specific transfer agency fees.
 
3. Agreements
Goldman Sachs Asset Management ("GSAM"), a separate operating division of
Goldman, Sachs & Co. ("Goldman Sachs"), acts as investment adviser (the
"Adviser") pursuant to an Investment Management Agreement (the "Agreement").
Under the Agreement, GSAM, subject to the general supervision by the Trust's
Board of Trustees, manages the portfolios and administers each portfolio's
business affairs, including providing facilities. As compensation for the
services rendered under the Agreement and the assumption of the expenses
related thereto, GSAM is entitled to a fee, computed daily and payable monthly,
at an annual rate equal to .35% of each portfolio's average daily net assets.
For the year ended December 31, 1998, GSAM has voluntarily agreed to waive a
portion of its management fees for the Money Market, Treasury Instruments,
Federal, Tax-Exempt Diversified and Tax-Exempt New York Portfolios,
respectively.
 Goldman Sachs acts as ILA's distributor under a Distribution Agreement for
which it receives no compensation except for a portion of the ILA Prime
Obligations Class B and Class C contingent deferred sales charges. Goldman
Sachs has advised the Portfolio that it retained approximately $2,000 for the
period ended December 31, 1998.
 GSAM had voluntarily agreed to reduce or limit the total operating expenses of
each Portfolio (excluding distribution and service fees, administration and
service plan fees, taxes, interest, brokerage commissions, litigation,
indemnification and other extraordinary expenses) on an annualized basis to
approximately .43% of the average net assets of each portfolio.
 For the year ended December 31, 1998, the Adviser waived certain fees and
expenses such that annualized "Management Fees", "Other Expenses (including
transfer agent fees)" and "Total Operating Expenses" (as defined above)
actually incurred by the portfolios based on average net assets were as
follows:

 The ILA Class B Units, ILA Class C Units and Cash Management Shares have each
adopted a Distribution Plan (the "Distribution Plan") pursuant to Rule 12b-1.
Under the Distribution Plan, Goldman Sachs is entitled to a quarterly fee for
distribution services equal, on an annual basis, of up to .75% of the average
daily net assets attributable to ILA Class B Units and ILA Class C Units and
..50% of the average daily net assets attributable to Cash Management Shares.
For the period ended December 31, 1998, GSAM has voluntarily agreed to
                                         ---------------------------------------

3. Agreements (continued)
waive a portion of the Cash Management Shares Distribution Fees.
 The ILA Class B Units and ILA Class C Units of Prime Obligations Portfolio had
also adopted an Authorized Dealer Service Plan (the "Dealer Service Plan")
pursuant to which Goldman Sachs and Authorized Dealers are compensated for
providing personal and account maintenance services. ILA Class B Units and ILA
Class C Units pay a fee under this Dealer Service Plan equal, on an annual
basis, to .25% of ILA Class B and Class C units' average daily net assets.
 Effective September 1, 1998, the Distribution Plans and Dealer Service Plans
were combined into Distribution and Service Plans. Under the Distribution and
Service Plans, Goldman Sachs and/or Authorized Dealers are entitled to a
monthly fee from each Portfolio for distribution services equal to, on an
annual basis, 1.00% of the average daily net assets attributable to Class B and
Class C units and 50% of the average daily net assets attributable to Cash
Management shares.
 Goldman Sachs also serves as the Transfer Agent and is entitled to a fee
calculated daily and payable monthly at an annual rate of .04% of the average
daily net assets of each class.

year ended December 31, 1998 (in thousands):

4. Administration, Service and Cash Management Plans
ILA has adopted Administration and Service Plans. These plans allow for ILA
Administration Units, ILA Service Units and Cash Management Shares,
respectively, to compensate service organizations for providing varying levels
of account administration and unitholder liaison services to their customers
who are beneficial owners of such units. The Administration, Service and Cash
Management Shares Plans provide for compensation to the service organizations
in an amount up to .15%, .40% and .50% (on an annualized basis), respectively,
of the average daily net asset value of the respective units/shares.
 
5. Line of Credit Facility
ILA participates in a $250,000,000 uncommitted, unsecured revolving line of
credit facility to be used solely for temporary or emergency purposes. Under
the most restrictive arrangement, each Portfolio must own securities having a
market value in excess of 300% of the total bank borrowings. The interest rate
on the borrowings is based on the Federal Funds rate. During the year ended
December 31, 1998, ILA did not have any borrowings under this facility.

6. Repurchase Agreements
During the term of a repurchase agreement, the value of the underlying
securities, including accrued interest, is required to equal or exceed the
value of the repurchase agreement. The underlying securities for all repurchase
agreements are held in safekeeping by a custodian.
 
7. Joint Repurchase Agreement Accounts
The ILA Portfolios, together with other registered investment companies having
management agreements with GSAM or its affiliates, may transfer uninvested cash
balances into joint accounts, the daily aggregate balances of which are
invested in one or more repurchase agreements.
 At December 31, 1998, the Prime Obligations, Money Market, Government and
Treasury Obligations Portfolios had investments in the following joint
repurchase account of $123,400,000, $68,900,000, $95,400,000 and $294,200,000
in principal amount, respectively. At December 31, 1998, the repurchase
agreements held in this joint account were fully collateralized by U.S.
Treasury obligations.

Letter to Shareholders
 
- ---------------------------------------  ---------------------------------------
Dear Shareholders:
 
  We welcome this opportunity to provide you with a summary of the trends and
key events that affected the economy and the Goldman Sachs Money Market
Trust/Financial Square Funds in 1998. It was another strong year for the funds,
during which all of them outperformed their respective IBC Financial Data, Inc.
averages. Net assets in the Financial Square Funds totaled $27.5 billion as of
December 31, 1998.
 
The Economy In Review
  Despite a slight tempering due to soft employment numbers, the U.S. economy
continued to see strong growth for most of 1998. This growth, combined with
continued uncertainty about the impact of Asian instability on the U.S.
economy, kept the Federal Reserve in a wait-and-see mode for the first nine
months of the year.
  On September 29th, in the wake of increasing global market turmoil, the
Federal Reserve Board cut the federal fund's target rate by 25 basis points, to
5.25%. As increasing illiquidity concerns in the market became more severe, the
Fed followed up with two more surprise rate cuts, easing the target rate and
the discount rate by another 50 basis points.
  The Fed's moves were a strong signal that the monetary authorities were
prepared to do whatever was necessary to provide liquidity and to support the
economy against the potential of a substantial economic slowdown in 1999.
  At period end, while consumer spending remained strong, the manufacturing
side of the economy appeared to weaken because of a trade drag and a slowdown
in capital spending. However, based on signs of non-inflationary growth in the
areas of consumer spending, new home sales and strong third quarter gross
domestic product (GDP), the general consensus is that any further easing by the
Fed will come later, rather than sooner.
 
Credit Year 1998: A Year of Crisis With a Hopeful Ending
  Domestic credit quality continued its strong positive trend for the first six
months of 1998. Mergers and acquisitions were at an all time high. U.S. banks
remained strong, well capitalized and provisioned, with diversified operations.
The stock market continued its climb and American consumers were spending more
than they were earning. The shocks of the Russian default in August and the
near collapse of Long Term Capital Management (LTCM) caused severe liquidity
problems and a difficult trading environment, as well as a major sell-off in
the stock market. Calm was restored by the rescue of LTCM and the Fed's
lowering of interest rates three times in seven weeks. A newly risk averse
investor moved funds to safer, more liquid credits. The enthusiasm for
globalization was temporarily curbed, as domestic production was suppressed in
response to the Asian crisis and corporate profit gains for the year were
generally mixed.
  The international credit environment in 1998 saw the Asian situation explode
into a full-blown global crisis that adversely affected markets around the
world. The default and devaluation of Russia in August came after an already
painful several months of recession and restructuring in Asia. This pain was
exacerbated by Japan's continued slow economic deterioration, which cast a
shadow over the entire region. The unprecedented market volatility that
followed Russia's default took months to dissipate, and only after a more
committed response by the U.S. government to the crisis. By the end of the
year, however, trends were much more positive. The reforming Asian economies
showed notable progress, with signs of a return to economic growth in 1999.
More significant, however, was the successful launch of the euro. Ongoing
policy convergence and political resolution served to create the world's first
regional currency with nary a ripple in the markets. In fact, with the U.S.
economy seemingly impervious to difficulties elsewhere, global markets quickly
rebounded to close the year on a decidedly positive note.

  Although the U.S. economy remains favorable, the challenges of global
volatility continue to concern us. The Goldman Sachs Credit Department, with
analysts based in London, Tokyo, Frankfurt and New York, as well as extensive
technological assets and credit expertise, will continue to anticipate and
monitor global developments and apply its conservative credit standards to the
money market portfolios.
 
Strategy
  Taxable. For most of the period, a "flight to quality" resulting from the
ongoing Asian economic crisis rendered the short end of the yield curve
expensive. In view of this, the Funds maintained a neutral stance by buying on
market dips and "aging in" when levels got expensive. However, we extended the
weighted average maturity (WAM) ranges from neutral to slightly long as the Fed
began its series of easings in late September in response to market liquidity.
We continued to maintain a barbell structure by holding significant liquidity
in anticipation of year-end outflows, and targeted longer dated maturities to
enhance performance in a declining rate environment.
  Tax-Exempt. Early in the period, given the fact that we no longer foresaw a
near-term Fed easing and in preparation for the seasonally short supply of
municipal issuance in January, we increased the funds' WAMs to the 40- to 50-
day range. This decision helped keep the funds' yields competitive during this
period of high cash inflows and high demand for municipal securities. In March,
we shortened the WAMs of the funds to the 30- to 35-day range, seeking to build
liquidity as the April 15th tax deadline approached. This move helped us to
fund tax-time redemptions. In August, when seasonal issuance was strong and
there was less demand in the tax-exempt market in contrast to the "flight to
quality" in the Treasury market, we extended the funds' WAMs to the 40-day
range.
  At period end, after a brief period during which the funds' WAMs were brought
into a neutral range, we extended the WAMs in anticipation of technically
driven lower yields (due to inflows from the reinvestment of maturity proceeds,
coupled with a seasonal scarcity of issuance).

*Financial Square Funds offer four separate classes of shares (Institutional,
Preferred, Administration and Service), each of which is subject to different
fees and expenses that affect performance and entitle shareholders to different
services. The Preferred, Administration and Service shares offer financial
institutions the opportunity to receive a fee for providing administrative
support services. The Preferred shares pay 0.10%, Administration shares pay
0.25%, and the Service shares pay 0.50%. If these fees were reflected in the
above performance, performance would be reduced. Past performance is no
guarantee of future results. Yields will vary. An investment in any one of the
Financial Square Funds is neither insured nor guaranteed by the U.S. Government
nor is there any assurance that the Funds will be able to maintain a stable net
asset value of $1.00 per share. More complete information, including management
fees and expenses, is included in the funds' prospectus or may be obtained by
calling Goldman Sachs Funds at 1-800-621-2550.
 
Outlook and Strategies for 1999
  With the financing pressure of year-end behind institutional investors, we
are looking to extend the funds' weighted average maturities somewhat as we see
opportunities on the yield curve. While there are a

variety of opinions as to when the Fed will move, based on current signs of
non-inflationary growth in areas of consumer spending, new home sales and
fourth quarter GDP, most economists anticipate that easing will come later
rather than sooner. Goldman Sachs economists' 1999 outlook anticipates a 50
basis point cumulative ease in the second half of the year.
  In closing, we thank you for your support and for making 1998 a year of
record assets for the Financial Square money market funds. As in the past, we
will continue to look for additional ways to improve our services, while
seeking to provide you with competitive performance. We welcome your
suggestions and questions, and look forward to another productive year in 1999.

Goldman Sachs Trust--Financial Square Funds
- --------------------------------------------------------------------------------
Notes to Financial Statements
December 31, 1998
- ---------------------------------------  ---------------------------------------
1. Organization
The Goldman Sachs Trust (the "Trust") is a Delaware business trust registered
under the Investment Company Act of 1940 (as amended) as an open-end management
investment company. The Trust includes the Financial Square Funds, collectively
"the Funds" or individually a "Fund". Financial Square consists of nine
diversified funds: Prime Obligations, Money Market, Premium Money Market,
Treasury Obligations, Treasury Instruments, Government, Federal, Tax-Free Money
Market and Municipal Money Market (inactive as of December 31, 1998). The
Financial Square Funds offer four classes of shares: FST shares, FST Preferred
shares, FST Administration shares and FST Service shares. The investment
objective of the Funds is to maximize current income to the extent consistent
with the preservation of capital and maintenance of liquidity. In addition, the
Tax-Free Money Market Fund seeks to provide shareholders with a high level of
income exempt from federal income tax.
 
2. Significant Accounting Policies
The following is a summary of significant accounting policies consistently
followed by the Funds. The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that may affect the reported amounts.
 
A. Investment Valuation--
Each Fund uses the amortized-cost method for valuing portfolio securities,
which approximates market value. Under this method, all investments purchased
at a discount or premium are valued by amortizing the difference between the
original purchase price and maturity value of the issue over the period to
maturity.
 
B. Interest Income--
Interest income is determined on the basis of interest accrued, premium
amortized and discount earned.
 
C. Federal Taxes--
It is each Fund's policy to comply with the requirements of the Internal
Revenue Code applicable to regulated investment companies and to distribute
each year substantially all investment company taxable and tax-exempt income to
shareholders. Accordingly, no federal tax provisions are required.
 The characterization of distributions to shareholders for financial reporting
purposes is determined in accordance with federal income tax rules. Therefore,
the source of the Funds' distributions may be shown in the accompanying
financial statements as either from or in excess of net investment income or
net realized gain on investment transactions, or from paid-in capital,
depending on the type of book/tax differences that may exist.
 At December 31, 1998 (tax year-end), the following fund had a capital loss
carryforward for U.S. Federal tax purposes of approximately:

       Fund                                                  Amount  Expiration

Tax-Free Money Market....................................... $11,000 2003-2005
</TABLE>
 
This amount is available to be carried forward to offset future capital gains
to the extent permitted by applicable laws or regulations.
 
D. Deferred Organization Expenses--
Organization-related costs are amortized on a straight-line basis over a period
of five years.
 
E. Expenses--
Expenses incurred by the Funds that do not specifically relate to an individual
fund are generally allocated to the Funds based on the nature of the expense.
 Shareholders of FST Preferred, FST Administration and FST Service shares bear
all expenses and fees paid to service organizations for their services with
respect to such shares.

3. Agreements
Goldman Sachs Asset Management ("GSAM"), a separate operating division of
Goldman, Sachs & Co. ("Goldman Sachs"), acts as investment adviser (the
"Adviser") pursuant to an Investment Management Agreement (the "Agreement").
Under the Agreement, GSAM, subject to general supervision by the Trust's Board
of Trustees, manages the Funds' portfolios and administers each Fund's business
affairs, including providing facilities. As compensation for the services
rendered under the Agreement and the assumption of the expenses related
thereto, GSAM is entitled to a fee, computed daily and payable monthly, at an
annual rate equal to .205% of each Fund's average daily net assets.
 For the year ended December 31, 1998, GSAM has voluntarily agreed to waive a
portion of its management fee. In addition, GSAM has limited certain of each of
the Fund's expenses (excluding management fees, service organization fees,
taxes, interest, brokerage commissions, litigation, indemnification and other
extraordinary expenses) to the extent that such expenses exceed .01% per annum
of each Fund's average daily net assets.
 Goldman Sachs serves as Transfer Agent and Distributor of shares of the Funds
pursuant to Transfer Agent and Distribution Agreements and receives no separate
fee.
 The following chart outlines the fee waivers and expense reimbursements for
the year ended December 31, 1998 (in thousands):

5.Line of Credit Facility
The Funds participate in a $250,000,000 uncommitted, unsecured revolving line
of credit facility to be used solely for temporary or emergency purposes. Under
the most restrictive arrangement, each Fund must own securities having a market
value in excess of 300% of the total bank borrowings. The interest rate on the
borrowings is based on the Federal Funds rate. During the year ended December
31, 1998, the Funds did not have any borrowings under this facility.
 
6.Repurchase Agreements
During the term of a repurchase agreement, the value of the underlying
securities, including accrued interest, is required to equal or exceed the
value of the repurchase agreement. The underlying securities for all repurchase
agreements are held in safekeeping at a custodian.
 
7.Joint Repurchase Agreement Accounts
The Funds, together with other registered investment companies having
management agreements with GSAM or its affiliates, transfer uninvested cash
balances into joint accounts, the daily aggregate balances of which are
invested in one or more repurchase agreements.
 At December 31, 1998, the Prime Obligations, Money Market, Premium Money
Market, Treasury Obligations and Government Funds had undivided interests in
the repurchase agreements held in the following joint account, which equaled

obligations.

To the Shareholders and Board of Trustees of
Goldman Sachs Trust--Financial Square Funds:
 
 We have audited the accompanying statements of assets and liabilities of
Goldman Sachs Trust--Financial Square Funds (a Delaware Business Trust
comprising the Prime Obligations, Money Market, Premium Money Market, Treasury
Obligations, Treasury Instruments, Government, Federal and Tax-Free Money
Market Funds), including the statements of investments, as of December 31,
1998, and the related statements of operations and the statements of changes in
net assets and the financial highlights for the periods presented. These
financial statements and the financial highlights are the responsibility of the
Funds' management. Our responsibility is to express an opinion on these
financial statements and the financial highlights based on our audits.
 
 We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
securities owned as of December 31, 1998 by correspondence with the custodian
and brokers. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
 In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective Funds constituting Goldman Sachs Trust--Financial Square
Funds as of December 31, 1998, the results of their operations and the changes
in their net assets and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.

COMMERCIAL PAPER RATINGS
- ------------------------

  A Standard & Poor's ("S&P") commercial paper rating is a current assessment of
the likelihood of timely payment of debt having an original maturity of no more
than 365 days.  The following summarizes the rating categories used by Standard
and Poor's for commercial paper:

  "A-1" - Obligations are rated in the highest category indicating that the
obligor's capacity to meet its financial commitment on the obligation is strong.
Within this category, certain obligations are designated with a plus sign (+).
This indicates that the obligor's capacity to meet its financial commitment on
these obligations is extremely strong.

  "A-2" - Obligations are somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than obligations in higher
rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

  "A-3" - Obligations exhibit adequate protection parameters.  However, adverse
economic conditions or changing circumstances are more likely to lead to a
weakened capacity of the obligor to meet its financial commitment on the
obligation.

  "B" - Obligations are regarded as having significant speculative
characteristics.  The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

  "C" - Obligations are currently vulnerable to nonpayment and are dependent
upon favorable business, financial, and economic conditions for the obligor to
meet its financial commitment on the obligation.

  "D" - Obligations are in payment default.  The "D" rating category is used
when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless S&P believes that such payments
will be made during such grace period.  The "D" rating will be used upon the
filing of a bankruptcy petition or the taking of a similar action if payments on
an obligation are jeopardized.

  Moody's commercial paper ratings are opinions of the ability of issuers to
repay punctually senior debt obligations not having an original maturity in
excess of one year, unless explicitly noted.  The following summarizes the
rating categories used by Moody's for commercial paper:

  "Prime-1" - Issuers (or supporting institutions) have a superior ability for
repayment of senior short-term debt obligations.  Prime-1 repayment ability will
often be      


                                      A-1
<PAGE>
 
    
evidenced by many of the following characteristics:  leading market
positions in well-established industries; high rates of return on funds
employed; conservative capitalization structure with moderate reliance on debt
and ample asset protection; broad margins in earnings coverage of fixed
financial charges and high internal cash generation; and well-established access
to a range of financial markets and assured sources of alternate liquidity.     

         
    
  "Prime-2" - Issuers (or supporting institutions) have a strong ability for
repayment of senior short-term debt obligations.  This will normally be
evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation.  Capitalization characteristics, while still appropriate, may be more
affected by external conditions.  Ample alternate liquidity is maintained.

  "Prime-3" - Issuers (or supporting institutions) have an acceptable ability
for repayment of senior short-term debt obligations.  The effect of industry
characteristics and market compositions may be more pronounced.  Variability in
earnings and profitability may result in changes in the level of debt protection
measurements and may require relatively high financial leverage.  Adequate
alternate liquidity is maintained.     
    
  "Not Prime" - Issuers do not fall within any of the Prime rating categories.
     

    
  The three rating categories of Duff & Phelps for investment grade commercial
paper and short-term debt are "D-1," "D-2" and "D-3."  Duff & Phelps employs
three designations, "D-1+," "D-1" and "D-1-," within the highest rating
category.  The following summarizes the rating categories used by Duff & Phelps
for commercial paper:     
    
  "D-1+" - Debt possesses the highest certainty of timely payment.  Short-term
liquidity, including internal operating factors and/or access to alternative
sources of funds, is outstanding, and safety is just below risk-free U.S.
Treasury short-term obligations.     
    
  "D-1" - Debt possesses very high certainty of timely payment.  Liquidity
factors are excellent and supported by good fundamental protection factors.
Risk factors are minor.     


                                      A-2
<PAGE>
 
    
  "D-1-" - Debt possesses high certainty of timely payment.  Liquidity factors
are strong and supported by good fundamental protection factors.  Risk factors
are very small.

  "D-2" - Debt possesses good certainty of timely payment.  Liquidity factors
and company fundamentals are sound.  Although ongoing funding needs may enlarge
total financing requirements, access to capital markets is good. Risk factors
are small.

  "D-3" - Debt possesses satisfactory liquidity and other protection factors
qualify issues as to investment grade.  Risk factors are larger and subject to
more variation.  Nevertheless, timely payment is expected.

  "D-4" - Debt possesses speculative investment characteristics.  Liquidity is
not sufficient to insure against disruption in debt service.  Operating factors
and market access may be subject to a high degree of variation.

  "D-5" - Issuer has failed to meet scheduled principal and/or interest
payments.

  Fitch IBCA short-term ratings apply to debt obligations that have time
horizons of less than 12 months for most obligations, or up to three years for
U.S. public finance securities.  The following summarizes the rating categories
used by Fitch IBCA for short-term obligations:

  "F1" - Securities possess the highest credit quality.  This designation
indicates the strongest capacity for timely payment of financial commitments and
may have an added "+" to denote any exceptionally strong credit feature.

  "F2" - Securities possess good credit quality.  This designation indicates a
satisfactory capacity for timely payment of financial commitments, but the
margin of safety is not as great as in the case of the higher ratings.

  "F3" - Securities possess fair credit quality.  This designation indicates
that the capacity for timely payment of financial commitments is adequate;
however, near-term adverse changes could result in a reduction to non-investment
grade.

  "B" - Securities possess speculative credit quality.  This designation
indicates minimal capacity for timely payment of financial commitments, plus
vulnerability to near-term adverse changes in financial and economic conditions.

  "C" - Securities possess high default risk.  This designation indicates that
default is a real possibility and that the capacity for meeting financial
commitments is solely reliant upon a sustained, favorable business and economic
environment.     

                                      A-3
<PAGE>
 
    
  "D" - Securities are in actual or imminent payment default.


  Thomson BankWatch short-term ratings assess the likelihood of an untimely
payment of principal and interest of debt instruments with original maturities
of one year or less.  The following summarizes the ratings used by Thomson
BankWatch:

  "TBW-1" - This designation represents Thomson BankWatch's highest category and
indicates a very high likelihood that principal and interest will be paid on a
timely basis.

  "TBW-2" - This designation represents Thomson BankWatch's second-highest
category and indicates that while the degree of safety regarding timely
repayment of principal and interest is strong, the relative degree of safety is
not as high as for issues rated "TBW-1."

  "TBW-3" - This designation represents Thomson BankWatch's lowest investment-
grade category and indicates that while the obligation is more susceptible to
adverse developments (both internal and external) than those with higher
ratings, the capacity to service principal and interest in a timely fashion is
considered adequate.

  "TBW-4" - This designation represents Thomson BankWatch's lowest rating
category and indicates that the obligation is regarded as non-investment grade
and therefore speculative.


CORPORATE AND MUNICIPAL LONG-TERM DEBT RATINGS
- ----------------------------------------------

  The following summarizes the ratings used by Standard & Poor's for corporate
and municipal debt:

  "AAA" - An obligation rated "AAA" has the highest rating assigned by Standard
& Poor's.  The obligor's capacity to meet its financial commitment on the
obligation is extremely strong.

  "AA" - An obligation rated "AA" differs from the highest rated obligations
only in small degree.  The obligor's capacity to meet its financial commitment
on the obligation is very strong.

  "A" - An obligation rated "A" is somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher-rated categories.  However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.     

                                      A-4
<PAGE>
 
    
  "BBB" - An obligation rated "BBB" exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

  Obligations rated "BB," "B," "CCC," "CC," and "C" are regarded as having
significant speculative characteristics.  "BB" indicates the least degree of
speculation and "C" the highest.  While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.

  "BB" - An obligation rated "BB" is less vulnerable to nonpayment than other
speculative issues.  However, it faces major ongoing uncertainties or exposure
to adverse business, financial or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.

  "B" - An obligation rated "B" is more vulnerable to nonpayment than
obligations rated "BB", but the obligor currently has the capacity to meet its
financial commitment on the obligation.  Adverse business, financial or economic
conditions will likely impair the obligor's capacity or willingness to meet its
financial commitment on the obligation.

  "CCC" - An obligation rated "CCC" is currently vulnerable to nonpayment, and
is dependent upon favorable business, financial and economic conditions for the
obligor to meet its financial commitment on the obligation.  In the event of
adverse business, financial, or economic conditions, the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.

  "CC" - An obligation rated "CC" is currently highly vulnerable to nonpayment.

  "C" - The "C" rating may be used to cover a situation where a bankruptcy
petition has been filed or similar action has been taken, but payments on this
obligation are being continued.     

         


                                      A-5
<PAGE>
 
         

    
  "D" - An obligation rated "D" is in payment default.  The "D" rating category
is used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless S&P believes that such payments
will be made during such grace period.  The "D" rating also will be used upon
the filing of a bankruptcy petition or the taking of a similar action if
payments on an obligation are jeopardized.

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

  "r" - This symbol is attached to the ratings of instruments with significant
noncredit risks.  It highlights risks to principal or volatility of expected
returns which are not addressed in the credit rating.  Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk  such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

The following summarizes the ratings used by Moody's for corporate and municipal
long-term debt:

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

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

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

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


                                      A-6
<PAGE>
 
    
  "Ba," "B," "Caa," "Ca," and "C" - Bonds that possess one of these ratings
provide questionable protection of interest and principal ("Ba" indicates
speculative elements; "B" indicates a general lack of characteristics of
desirable investment; "Caa" are of poor standing; "Ca" represents obligations
which are speculative in a high degree; and "C" represents the lowest rated
class of bonds). "Caa," "Ca" and "C" bonds may be in default.

  Con. (---) - Bonds for which the security depends upon the completion of some
act or the fulfillment of some condition are rated conditionally.  These are
bonds secured by (a) earnings of projects under construction, (b) earnings of
projects unseasoned in operating experience, (c) rentals which begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches.  Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.

  Note:  Moody's applies numerical modifiers 1, 2, and 3 in each generic rating
classification from "Aa" through "Caa".  The modifier 1 indicates that the
obligation ranks in the higher end of its generic rating category; the modifier
2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the
lower end of its generic rating category.

The following summarizes the long-term debt ratings used by Duff & Phelps for
corporate and municipal long-term debt:

  "AAA" - Debt is considered to be of the highest credit quality.  The risk
factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

  "AA" - Debt is considered to be of high credit quality.  Protection factors
are strong.  Risk is modest but may vary slightly from time to time because of
economic conditions.

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

  "BBB" - Debt possesses below-average protection factors but such protection
factors are still considered sufficient for prudent investment.  Considerable
variability in risk is present during economic cycles.

  "BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of these ratings is
considered to be below investment grade.  Although below investment grade, debt
rated "BB" is deemed likely to meet obligations when due.  Debt rated "B"
possesses the risk that obligations will not be met when due.  Debt rated "CCC"
is well below investment grade and has considerable uncertainty as to timely
payment of principal, interest or      


                                      A-7
<PAGE>
 
    
preferred dividends. Debt rated "DD" is a defaulted debt obligation, and the
rating "DP" represents preferred stock with dividend arrearages.

  To provide more detailed indications of credit quality, the "AA," "A," "BBB,"
"BB," and "B" ratings may be modified by the addition of a plus (+) or minus (-)
sign to show relative standing within these major categories. 

  The following summarizes the ratings used by Fitch IBCA for corporate and
municipal bonds: 

  "AAA" - Bonds considered to be investment grade and of the highest credit
quality.  These ratings denote the lowest expectation of credit risk and are
assigned only in case of exceptionally strong capacity for timely payment of
financial commitments.  This capacity is highly unlikely to be adversely
affected by foreseeable events. 

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

  "A" - Bonds considered to be investment grade and of high credit quality.
These ratings denote a low expectation of credit risk and indicate strong
capacity for timely payment of financial commitments.  This capacity may,
nevertheless, be more vulnerable to changes in circumstances or in economic
conditions than is the case for higher ratings.

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

  "BB" - Bonds considered to be speculative.  These ratings indicate that there
is a possibility of credit risk developing, particularly as the result of
adverse economic changes over time; however, business or financial alternatives
may be available to allow financial commitments to be met.  Securities rated in
this category are not investment grade.

  "B" - Bonds are considered highly speculative.  These ratings indicate that
significant credit risk is present, but a limited margin of safety remains.
Financial commitments are currently being met; however, capacity for continued
payment is contingent upon a sustained, favorable business and economic
environment.

  "CCC," "CC," and "C" - Bonds have high default risk.  Default is a real
possibility, and capacity for meeting financial commitments is solely reliant
upon sustained, favorable business or economic developments.  "CC" ratings
indicate that default of some kind appears probable, and "C" ratings signal
imminent default.      



                                      A-8
<PAGE>
 
    
  "DDD," "DD," and "D" - Bonds are in default.  Securities are not meeting
obligations and are extremely speculative.  "DDD" designates the highest
potential for recovery of amounts outstanding on any securities involved and "D"
represents the lowest potential for recovery.

  To provide more detailed indications of credit quality, the Fitch IBCA ratings
from and including "AA" to "B" may be modified by the addition of a plus (+) or
minus (-) sign to show relative standing within these major rating categories.

  Thomson BankWatch assesses the likelihood of an untimely repayment of
principal or interest over the term to maturity of long term debt and preferred
stock which are issued by United States commercial banks, thrifts and non-bank
banks; non-United States banks; and broker-dealers.  The following summarizes
the rating categories used by Thomson BankWatch for long-term debt ratings:

  "AAA" - This designation indicates that the ability to repay principal and
interest on a timely basis is extremely high.

  "AA" - This designation indicates a very strong ability to repay principal and
interest on a timely basis, with limited incremental risk compared to issues
rated in the highest category.

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

  "BBB" - This designation represents the lowest investment-grade category and
indicates an acceptable capacity to repay principal and interest.  Issues rated
"BBB" are more vulnerable to adverse developments (both internal and external)
than obligations with higher ratings.

  "BB," "B," "CCC," and "CC" - These designations are assigned by Thomson
BankWatch to non-investment grade long-term debt.  Such issues are regarded as
having speculative characteristics regarding the likelihood of timely payment of
principal and interest.  "BB" indicates the lowest degree of speculation and
"CC" the highest degree of speculation.

  "D" - This designation indicates that the long-term debt is in default.

  PLUS (+) OR MINUS (-) - The ratings from "AAA" through "CC" may include a plus
or minus sign designation which indicates where within the respective category
the issue is placed.      



                                      A-9

MUNICIPAL NOTE RATINGS
- ----------------------

    
  A Standard and Poor's rating reflects the liquidity concerns and market access
risks unique to notes due in three years or less.  The following summarizes the
ratings used by Standard & Poor's Ratings Group for municipal notes:

  "SP-1" - The issuers of these municipal notes exhibit a strong capacity to pay
principal and interest.  Those issues determined to possess very strong
characteristics are given a plus (+) designation.

  "SP-2" - The issuers of these municipal notes exhibit satisfactory capacity to
pay principal and interest, with some vulnerability to adverse financial and
economic changes over the term of the notes.

  "SP-3" - The issuers of these municipal notes exhibit speculative capacity to
pay principal and interest.


  Moody's ratings for state and municipal notes and other short-term loans are
designated Moody's Investment Grade ("MIG") and variable rate demand obligations
are designated Variable Moody's Investment Grade ("VMIG").  Such ratings
recognize the differences between short-term credit risk and long-term risk.
The following summarizes the ratings by Moody's Investors Service, Inc. for
short-term notes:      

         
    
  "MIG-1"/"VMIG-1" - This designation denotes best quality.  There is present
strong protection by established cash flows, superior liquidity support or
demonstrated broad-based access to the market for refinancing.

  "MIG-2"/"VMIG-2" - This designation denotes high quality, with margins of
protection that are ample although not so large as in the preceding group.

  "MIG-3"/"VMIG-3" - This designation denotes favorable quality, with all
security elements accounted for but lacking the undeniable strength of the
preceding grades.  Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.      



                                     A-10
<PAGE>
 
      
  "MIG-4"/"VMIG-4" - This designation denotes adequate quality.  Protection
commonly regarded as required of an investment security is present and although
not distinctly or predominantly speculative, there is specific risk.

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

  Fitch IBCA and Duff & Phelps use the short-term ratings described under
Commercial Paper Ratings for municipal notes.

                                  INTRODUCTION
                                            
          Goldman Sachs Trust (the "Trust") is an open-end management investment
company.  The Trust is organized as a Delaware business trust, and is a
successor to a Massachusetts business trust that was combined with the Trust on
April 30, 1997.  The following series of the Trust are described in this
Additional Statement: Goldman Sachs Conservative Strategy Portfolio
("Conservative Strategy Portfolio"), Goldman Sachs Balanced Strategy Portfolio
("Balanced Strategy Portfolio"), Goldman Sachs Growth and Income Strategy
Portfolio ("Growth and Income Strategy Portfolio"), Goldman Sachs Growth
Strategy Portfolio ("Growth Strategy Portfolio") and Goldman Sachs Aggressive
Growth Strategy Portfolio ("Aggressive Growth Strategy Portfolio") (each
referred to herein as a "Portfolio" and collectively referred to as the
"Portfolios").  The Trust assumed its current name on March 22, 1991.  The
Trustees of the Trust have authority under the Declaration of Trust to create
and classify shares into separate series and to classify and reclassify any
series of shares into one or more classes without further action by
shareholders.  Pursuant thereto, the Trustees have created the Portfolios and
other series.  Each Portfolio is each authorized to issue five classes of
shares:  Institutional Shares, Service Shares, Class A Shares, Class B Shares
and Class C Shares.  Additional series and classes may be added in the future
from time to time.     

          Each Portfolio is a separately managed, diversified mutual fund with
its own investment objectives and policies.  Each Portfolio has been constructed
as a "fund of funds," which means that it pursues its investment objective
primarily by allocating its investments among other investment portfolios of the
Trust (the "Underlying Funds").

          Goldman Sachs Asset Management ("GSAM"), a separate operating division
of Goldman, Sachs & Co. ("Goldman Sachs"), serves as investment adviser to each
Portfolio.  GSAM is sometimes referred to herein as the "Adviser."  Goldman
Sachs serves as each Portfolio's distributor and transfer agent.  Each
Portfolio's custodian is State Street Bank and Trust Company ("State Street").

                       INVESTMENT OBJECTIVES AND POLICIES
                                            
          Normally, each of the Portfolios will be predominantly invested in
shares of the Underlying Funds.  These Underlying Funds currently consist of the
Adjustable Rate Government Fund, Short Duration Government Fund, Government
Income Fund, Core Fixed Income Fund, Global Income Fund, High Yield Fund and
Growth and Income Fund (the "Underlying Fixed-Income Funds"); the CORE U.S.
Equity Fund, CORE Large Cap Growth Fund, CORE Large Cap Value Fund, CORE Small
Cap Equity Fund, Capital Growth Fund, Mid Cap Value Fund, Small Cap Value Fund,
CORE International Equity Fund, International Equity Fund, Emerging Markets
Equity Fund, Asia Growth Fund, European Equity Fund, Japanese Equity Fund,
International Small Cap Fund and Real Estate Securities Fund (the "Underlying
Equity Funds"); and the Financial Square Prime Obligations Fund. The value of
the Underlying Funds' investments, and the net asset value of the shares of both
the Underlying Funds and the Portfolios will fluctuate with market, economic
and, to the extent applicable, foreign exchange conditions, so that an
investment in any of the Portfolios may be worth more or less when redeemed than
when purchased. The following description provides additional information
regarding the Underlying Funds and the types of investments that the Underlying
Funds may make. As stated in the Portfolios' Prospectus, the Portfolios may
invest a portion of their assets in high    

                                      B-3

quality, short-term debt obligations. These obligations are also described
below in this section. Further information about the Underlying Funds and their
respective investment objectives and policies is included in their Prospectuses
and Additional Statements. There is no assurance that any Portfolio or
Underlying Fund will achieve its objective.     

                      A.  Description of Underlying Funds
                                        
Adjustable Rate Government Fund

          Objective.  This Fund seeks to provide investors with a high level of
          ---------                                                            
current income, consistent with low volatility of principal.

          Duration.  Under normal interest rate conditions, the Fund's duration
          --------                                                             
is expected to be in a range approximately equal to that of a six-month to one-
year U.S. Treasury security.  In addition, under normal interest rate
conditions, the Fund's maximum duration will not exceed two years.  The
approximate interest rate sensitivity of the Fund is expected to be comparable
to a nine-month note.

          Investment Sector.  This Fund invests, under normal circumstances, at
          -----------------                                                    
least 65% of its total assets in U.S. Government Securities that are adjustable
rate mortgage pass-through securities and other mortgage securities with
periodic interest rate resets.  The remainder of the Fund's assets (up to 35%)
may be invested in other U.S. Government Securities, including fixed rate
mortgage pass-through securities, other securities representing an interest in
or collateralized by adjustable rate and fixed rate mortgage loans ("Mortgage-
Backed Securities") and repurchase agreements collateralized by U.S. Government
Securities.  Substantially all of the Fund's assets will be invested in U.S.
Government Securities.  100% of the Fund's portfolio will be invested in U.S.
dollar-denominated securities.

          Credit Quality.  This Fund invests in U.S. Government Securities and
          --------------                                                      
repurchase agreements collateralized by such securities.

          Other.  This Fund may employ certain active management techniques to
          -----                                                               
manage its duration and term structure and to seek to enhance returns.  These
techniques include, but are not limited to, the use of financial futures
contracts, option contracts (including options on futures), mortgage and
interest rate swaps and interest rate floors, caps and collars. The Fund may
also employ other investment techniques to seek to enhance returns, such as
lending portfolio securities and entering into mortgage dollar rolls, repurchase
agreements and other investment practices.

Short Duration Government Fund

          Objective.  This Fund seeks to provide a high level of current income.
          ---------      
Secondarily, the Fund may, in seeking current income, also consider the
potential for capital appreciation.

          Duration.  Under normal interest rate conditions, the Fund's duration
          --------                                                             
is expected to be equal to that of the Fund's benchmark, the two-year U.S.
Treasury security, plus or minus .5 years.  In addition, under normal interest
rate conditions, the Fund's maximum duration will not exceed three years.  The
approximate interest rate sensitivity of the Fund is expected to be comparable
to a two-year bond.

          Investment Sector.  This Fund invests, under normal market conditions,
          -----------------                                                     
at least 65% of its total assets in U.S. Government Securities and in repurchase
agreements collateralized by such securities.  Substantially all of the Fund's
assets will be invested in U.S. Government Securities.  100% of the Fund's
portfolio will be invested in U.S. dollar-denominated securities.

          Credit Quality.  This Fund invests in U.S. Government Securities and
          --------------                                                      
repurchase agreements collateralized by such securities.

          Other.  This Fund may employ certain active management techniques to
          -----                                                               
manage its duration and term structure and to seek to enhance returns.  These
techniques include, but are not limited to, the use of financial futures
contracts, option contracts (including options on futures), mortgage and
interest rate swaps and interest rate floors, caps and collars.  The Fund may
also employ other investment techniques to seek to enhance returns, such as
lending portfolio securities and entering into mortgage dollar rolls, repurchase
agreements and other investment practices.

Government Income Fund

          Objective.  This Fund seeks to provide investors with a high level of
          ---------                                                            
current income, consistent with safety of principal.

          Duration.  Under normal interest rate conditions, the Fund's duration
          --------                                                             
is expected to be equal to that of the Fund's benchmark, the Lehman Brothers
Mutual Fund Government/Mortgage Index, plus or minus one year.  In addition,
under normal interest rate conditions, the Fund's maximum duration will not
exceed six years.  The approximate interest rate sensitivity of the Fund is
expected to be comparable to a five-year bond.

          Investment Sector.  This Fund invests, under normal circumstances, at
          -----------------                                                    
least 65% of its total assets in U.S. Government Securities and in repurchase
agreements collateralized by such securities.  The remainder of the Fund's
assets may be invested in non-government securities such as privately issued
Mortgage-Backed Securities, Asset-Backed Securities and corporate securities.
100% of the Fund's portfolio will be invested in U.S. dollar-denominated
securities.

          Credit Quality.  This Fund's non-U.S. Government Securities will be
          --------------                                                     
rated, at the time of investment, AAA or Aaa by a Nationally Recognized
Statistical Rating Organization (an "NRSRO") or, if unrated, will be determined
by the Fund's investment adviser to be of comparable quality.

          Other.  This Fund may employ certain active management techniques to
          -----                                                               
manage its duration and term structure and to seek to enhance returns.  These
techniques include, but are not limited to, the use of financial futures
contracts, option contracts (including options on futures), mortgage and
interest rate swaps and interest rate floors, caps and collars.  The Fund may
also employ other investment techniques to seek to enhance returns, such as
lending portfolio securities and entering into mortgage dollar rolls, repurchase

Core Fixed Income Fund

          Objective.  This Fund seeks to provide investors with a total return
          ---------                                                           
consisting of capital appreciation and income that exceeds the total return of
the Lehman Brothers Aggregate Bond Index (the "Index").

          Duration.  Under normal interest rate conditions, the Fund's duration
          --------                                                             
is expected to be equal to that of the Fund's benchmark, the Lehman Brothers
Aggregate Bond Index, plus or minus one year. In addition, under normal interest
rate conditions, the Fund's maximum duration will not exceed six years.  The
approximate interest rate sensitivity of the Fund is expected to be comparable
to a five-year bond.

          Investment Sector.  This Fund invests, under normal circumstances, at
          -----------------                                                    
least 65% of its total assets in fixed-income securities, including U.S.
Government Securities, corporate debt securities, Mortgage-Backed Securities,
and Asset-Backed Securities.  The Fund may invest up to 25% of its total assets
in obligations of domestic and foreign issuers which are denominated in
currencies other than the U.S. dollar, 10% of which may be invested in issuers
in countries with emerging markets and economies.  A number of investment
strategies will be used to achieve the Fund's investment objective, including
market sector selection, determination of yield curve exposure, and issuer
selection.  In addition, the Investment Adviser will attempt to take advantage
of pricing inefficiencies in the fixed-income markets.
    
          The Index currently includes U.S. Government Securities and fixed-
rate, publicly issued, U.S. dollar-denominated fixed-income securities rated at
least BBB or Baa by an NRSRO.  Securities rated BBB or Baa are considered
medium-grade obligations with speculative characteristics, and adverse economic
conditions or changing circumstances may weaken their issuers' capability to pay
interest and repay principal.  The securities currently included in the Index
have at least one year remaining to maturity; have an outstanding principal
amount of at least $100 million; and are issued by the following types of
issuers, with each category receiving a different weighting in the Index:  U.S.
Treasury; agencies, authorities or instrumentalities of the U.S. government;
issuers of Mortgage-Backed Securities; utilities; industrial issuers; financial
institutions; foreign issuers; and issuers of Asset-Backed Securities.  The
Index is a trademark of Lehman Brothers.  Inclusion of a security in the Index
does not imply an opinion by Lehman Brothers as to its attractiveness or
appropriateness for investment.  Although Lehman Brothers obtains factual
information used in connection with the Index from sources which it considers
reliable, Lehman Brothers claims no responsibility for the accuracy,
completeness or timeliness of such information and has no liability to any
person for any loss arising from results obtained from the use of the Index
data.     
    
          Credit Quality.  All U.S. dollar-denominated fixed-income securities
          --------------                                                      
purchased by the Fund will be rated, at the time of investment, at least BBB or
Baa by an NRSRO or, if unrated, will be determined by the Fund's investment
adviser to be of comparable quality.  The non-U.S. dollar-denominated fixed-
income securities in which the Fund may invest will be rated, at the time of
investment, at least AA or Aa by an NRSRO or, if unrated, will be determined by
the Fund's investment adviser to be of comparable quality.  Fixed-income
securities rated BBB or Baa are considered medium-grade obligations with
speculative characteristics and adverse economic conditions or changing
circumstances may weaken their issuers' capability to pay interest and repay
principal.

          Other.  This Fund may employ certain active management techniques to
          -----                                                               
manage its duration and term structure, to seek to hedge its exposure to foreign
currencies and to seek to enhance returns.  These techniques include, but are
not limited to, the use of financial futures contracts, option contracts
(including options on futures), forward foreign currency exchange contracts,
currency options and futures, currency, credit, mortgage and interest rate swaps
and interest rate floors, caps and collars.  Currency management techniques
involve risks different from those associated with investing solely in U.S.
dollar-denominated fixed-income securities of U.S. issuers.  It is expected that
the Fund will use certain currency techniques to seek to hedge against currency
exchange rate fluctuations or to seek to increase total return. The Fund may
invest in custodial receipts, Municipal Securities and convertible securities.
The Fund may also employ other investment techniques to seek to enhance returns,
such as lending portfolio securities and entering into mortgage dollar rolls,
repurchase agreements and other investment practices.

Global Income Fund

          Objective.  This Fund seeks to provide investors with a high total
          ---------                                                         
return, emphasizing current income, and, to a lesser extent, providing
opportunities for capital appreciation.

          Duration.  Under normal interest rate conditions, the Fund's duration
          --------                                                             
is expected to be equal to that of the Fund's benchmark, the J.P. Morgan Global
Government Bond Index (hedged), plus or minus 2.5 years.  In addition, under
normal interest rate conditions, the Fund's maximum duration will not exceed 7.5
years.  The approximate interest rate sensitivity of the Fund is expected to be
comparable to a six-year bond.

          Investment Sector.  The Fund invests primarily in a portfolio of high
          -----------------                                                    
quality fixed-income securities of U.S. and foreign issuers and enters into
transactions in foreign currencies.  Under normal market conditions, the Fund
will (i) have at least 30% of its total assets, after considering the effect of
currency positions, denominated in U.S. dollars and (ii) invest in securities of
issuers in at least three countries.  The Fund may also invest up to 10% of its
total assets in issuers in countries with emerging markets and economies.  The
Fund seeks to meet its investment objective by pursuing investment opportunities
in foreign and domestic fixed-income securities markets and by engaging in
currency transactions to seek to enhance returns and to seek to hedge its
portfolio against currency exchange rate fluctuations.

          The fixed-income securities in which the Fund may invest include:  (i)
U.S. Government Securities and custodial receipts therefor; (ii) securities
issued or guaranteed by a foreign government or any of its political
subdivisions, authorities, agencies, instrumentalities or by supranational
entities (i.e., international organizations designated or supported by
governmental entities to promote economic reconstruction or development, such as
the World Bank); (iii) corporate debt securities; (iv) certificates of deposit
and bankers' acceptances issued or guaranteed by, or time deposits maintained
at, U.S. or foreign banks (and their branches wherever located) having total
assets of more than $1 billion; (v) commercial paper; and (vi) Mortgage-Backed
and Asset-Backed Securities.

          Credit Quality.  All securities purchased by the Fund will be rated,
          --------------                                                      
at the time of investment, at least BBB or Baa by an NRSRO.  However, the Fund
will invest at least 50% of its total assets in securities rated, at the time of
investment, AAA or Aaa by an NRSRO.  Unrated securities will be determined by
the Fund's investment adviser to be of comparable 

                                      B-7

quality. Securities rated BBB or Baa are considered medium-grade obligations
with speculative characteristics, and adverse economic conditions or changing
circumstances may weaken their issuers' capacity to pay interest and repay
principal.     

          Other.  This Fund may employ certain active management techniques to
          -----                                                               
manage its duration and term structure, to seek to hedge its exposure to foreign
currencies and to seek to enhance returns.  These techniques include, but are
not limited to, the use of financial futures contracts, option contracts
(including options on futures), forward foreign currency exchange contracts,
currency options and futures, currency, credit, mortgage and interest rate swaps
and interest rate floors, caps and collars.  Currency management techniques
involve risks different from those associated with investing solely in U.S.
dollar-denominated fixed-income securities of U.S. issuers.  It is expected that
the Fund will use certain currency techniques to seek to hedge against currency
exchange rate fluctuations or to seek to increase total return.  While the Fund
will have both long and short currency positions, its net long and short foreign
currency exposure will not exceed the value of the Fund's total assets.  To the
extent that the Fund is fully invested in foreign securities while also
maintaining currency positions, it may be exposed to greater combined risk.  The
Fund's net currency positions may expose it to risks independent of its
securities positions.  The Fund may also employ other investment techniques to
seek to enhance returns, such as lending portfolio securities and entering into
mortgage dollar rolls, repurchase agreements and other investment practices.

          The Fund may invest more than 25% of its total assets in the
securities of corporate and governmental issuers located in each of Canada,
Germany, Japan, and the United Kingdom as well as in the securities of U.S.
issuers.  Concentration of the Fund's investments in such issuers will subject
the Fund, to a greater extent than if investment was more limited, to the risks
of adverse securities markets, exchange rates and social, political or economic
events which may occur in those countries.  Not more than 25% of the Fund's
total assets will be invested in securities of issuers in any other single
foreign country.

High Yield Fund

          Objective.  This Fund seeks to provide investors with a high level of
          ---------                                                            
current income and may also consider the potential for capital appreciation.

          Duration.  Under normal interest rate conditions, the Fund's duration
          --------                                                             
is expected to be equal to that of the Fund's benchmark, the Lehman Brothers
High Yield Bond Index, plus or minus 2.5 years.  In addition, under normal
interest rate conditions, the Fund's maximum duration will not exceed 7.5 years.
The approximate interest rate sensitivity of the Fund is expected to be
comparable to a 6-year bond.

          Investment Sector.  This Fund invests, under normal circumstances, at
          -----------------                                                    
least 65% of its total assets in high yield, fixed-income securities rated, at
the time of investment, below investment grade.  Non-investment grade securities
are securities rated BB, Ba or below by an NRSRO, or, if unrated, determined by
the investment adviser to be of comparable quality.  The Fund may invest in all
types of fixed-income securities, including senior and subordinated corporate
debt obligations (such as bonds, debentures, notes and commercial paper),
convertible and non-convertible corporate debt obligations, loan participations,
custodial receipts, municipal securities and preferred stock.  The Fund may
invest up to 25% of its total assets in obligations of domestic and foreign
issuers (including securities of issuers 

                                      B-8
<PAGE>
 
located in countries with emerging markets and economies) which are denominated
in currencies other than the U.S. dollar. Under normal market conditions, the
Fund may invest up to 35% of its total assets in investment grade fixed-income
securities, including U.S. Government Securities, Asset-Backed and Mortgage-
Backed Securities and corporate securities. The Fund may also invest in common
stocks, warrants, rights and other equity securities, but will generally hold
such equity investments only when debt or preferred stock of the issuer of such
equity securities is held by the Fund. A number of investment strategies are
used to seek to achieve the Fund's investment objective, including market sector
selection, determination of yield curve exposure, and issuer selection. In
addition, the Fund's investment adviser will attempt to take advantage of
pricing inefficiencies in the fixed-income markets.
    
          Credit Quality.  This Fund invests primarily in high yield, fixed-
          --------------                                                   
income securities rated below investment grade, including securities of issuers
in default.  Non-investment grade securities (commonly known as "junk bonds")
tend to offer higher yields than higher rated securities with similar
maturities. Non-investment grade securities are, however, considered speculative
and generally involve greater price volatility and greater risk of loss of
principal and interest than higher rated securities.  See "Description of
Investment Securities and Practices."  A description of the corporate bond and
preferred stock ratings is contained in Appendix A to this Additional 
Statement.     

          Other.  This Fund may employ certain active management techniques to
          -----                                                               
manage its duration and term structure, to seek to hedge its exposure to foreign
securities and to seek to enhance returns.  These techniques include, but are
not limited to, the use of financial futures contracts, option contracts
(including options on futures), forward foreign currency exchange contracts,
currency options and futures, currency, credit, mortgage and interest rate
swaps, and interest rate floors, caps and collars.  Currency management
techniques involve risks different from those associated with investing solely
in U.S. dollar-denominated fixed-income securities of U.S. issuers.  It is
expected that the Fund will use certain currency techniques to seek to hedge
against currency exchange rate fluctuations or to seek to increase total return.
The Fund may also employ other investment techniques to seek to enhance returns,
such as lending portfolio securities and entering into repurchase agreements and
other investment practices.

Growth and Income Fund

          Objectives.  This Fund seeks to provide investors with long-term 
          ----------                             
growth of capital and growth of income.

          Primary Investment Focus.  This Fund invests, under normal
          ------------------------                                  
circumstances, at least 65% of its total assets in equity securities that its
investment adviser considers to have favorable prospects for capital
appreciation and/or dividend-paying ability.

          Other.  This Fund may invest up to 35% of its total assets in fixed-
          -----                                                              
income securities that, in the opinion of its investment adviser, offer the
potential to further the Fund's investment objectives.  In addition, although
the Fund will invest primarily in publicly traded U.S. securities, it may invest
up to 25% of its total assets in foreign securities, including securities of
issuers in Emerging Countries and securities quoted in foreign currencies.

CORE U.S. Equity Fund

          Objective.  This Fund seeks to provide investors with long-term growth
          ---------                                                             
of capital and dividend income.  The Fund seeks to achieve its objective through
a broadly diversified portfolio of large cap and blue chip equity securities
representing all major sectors of the U.S. economy.

circumstances, at least 90% of its total assets in equity securities of U.S.
issuers, including certain foreign issuers that are traded in the United States.
The Fund's investments are selected using both a variety of quantitative
techniques and fundamental research in seeking to maximize the Fund's expected
return, while maintaining risk, style, capitalization and industry
characteristics similar to the S&P 500 Index.  The Fund seeks a broad
representation in most major sectors of the U.S. economy and a portfolio
composed of companies with average long-term earnings growth expectations and
dividend yields.  The Fund's investments in fixed-income securities are limited
to securities that are considered cash equivalents.

of capital.  The Fund seeks to achieve its objective through a broadly
diversified portfolio of equity securities of large cap U.S. issuers that are
expected to have better prospects for earnings growth than the growth rate of
the general domestic economy.  Dividend income is a secondary consideration.

issuers, including certain foreign issuers that are traded in the United States.
The Fund's investment adviser emphasizes a company's growth prospects in
analyzing equity securities to be purchased by the Fund.  The Fund's investments
are selected using both a variety of quantitative techniques and fundamental
research in seeking to maximize the Fund's expected return, while maintaining
risk, style, capitalization and industry characteristics similar to the Russell
1000 Growth Index.  The Fund seeks a portfolio composed of companies with above
average capitalizations and earnings growth expectations and below average
dividend yields.  The Fund's investments in fixed-income securities are limited
to securities that are considered cash equivalents.

capital and dividend income.  The Fund seeks to achieve its objective through a
broadly diversified portfolio of equity securities of large cap U.S. issuers
that are selling at low to modest valuations relative to general market measures
such as earnings, book value and other fundamental accounting measures, and that
are expected to have favorable prospects for capital appreciation and/or
dividend-paying ability.

  Primary Investment Focus.  This Fund invests, under normal circumstances, at

similar to the Russell 1000 Value Index. The Fund seeks a portfolio composed of
companies with above average capitalizations and low to moderate valuations as
measured by price/earnings ratios, book value and other fundamental accounting
measures. The Fund's investments in fixed-income securities are limited to
securities that are considered cash equivalents.

capital.  The Fund seeks to achieve its objective through a broadly diversified
portfolio of equity securities of U.S. issuers which are included in the Russell
2000 Index at the time of investment.

    
  Primary Investment Focus.  This Fund invests, under normal circumstances, at

least 90% of its total assets in equity securities of U.S. issuers, including
certain foreign issuers that are traded in the United States.  The Fund's
investments are selected using both a variety of quantitative techniques and
fundamental research in seeking to maximize the Fund's expected return, while
maintaining risk, style, capitalization and industry characteristics similar to
the Russell 2000 Index.  The Fund seeks a portfolio composed of companies with
small market capitalizations, strong expected earnings growth and momentum, and
better valuation and risk characteristics than the Russell 2000 Index.  If the
issuer of a portfolio security held by the Fund is no longer included in the
Russell 2000 Index, the Fund may, but is not required to, sell the security.
The Fund's investments in fixed-income securities are limited to securities that
are considered cash equivalents.

securities that are considered by its investment adviser to have long-term
capital appreciation potential.

  ---------                                                              
appreciation.

  Primary Investment Focus.  This Fund invests, under normal circumstances,
  ------------------------                                                 
substantially all of its assets in equity securities and at least 65% of its
total assets in equity securities of Mid-Cap Companies with public stock market
capitalizations (based upon shares available for trading on an unrestricted
basis) within the range of the market capitalization of companies constituting
the Russell Midcap Index at the time of investment (currently between $400
million and $16 billion).  If the capitalization of an issuer increases above
$16 billion after purchase of such issuer's securities, the Fund may, but is not
required to, sell the securities.  Dividend income, if any, is an incidental
consideration.

traded U.S. securities, it may invest up to 25% of its total assets in foreign
securities, including securities of issuers in Emerging Countries and securities
quoted in foreign currencies.

Small Cap Value Fund

  Objective.  This Fund seeks to provide investors with long-term capital

growth.

  Primary Investment Focus.  This Fund invests, under normal circumstances, at
  ------------------------                                                    
least 65% of its total assets in equity securities of companies with public
stock market capitalizations of $1 billion or less at the time of investment.
Under normal circumstances, the Fund's investment horizon for ownership of
stocks will be two to three years.  Dividend income, if any, is an incidental
consideration.  If the market capitalization of a company held by the Fund
increases above the amount stated above, the Fund may, consistent with its
investment objective, continue to hold the security.

  Small Capitalization Companies.  This Fund invests in companies which its
  ------------------------------                                           
investment adviser believes are well managed niche businesses that have the
potential to achieve high or improving returns on capital and/or above average
sustainable growth.  The Fund may invest in securities of small market
capitalization companies which may have experienced financial difficulties.
Investments may also be made in companies that are in the early stages of their
life and that the Fund's investment adviser believes have significant growth
potential.  The investment adviser believes that the companies in which the Fund
may 

                                      B-12
<PAGE>
 
invest offer greater opportunity for growth of capital than larger, more mature,
better known companies. However, investments in such small market capitalization
companies involve special risks.

  Other.  This Fund may invest in the aggregate up to 35% of its total assets in
  -----                                                                         
the equity securities of companies with public stock market capitalizations in
excess of $1 billion at the time of investment and in fixed-income securities.
In addition, although the Fund will invest primarily in publicly traded U.S.
securities, it may invest up to 25% of its total assets in foreign securities,
including securities of issuers in Emerging Countries and securities quoted in
foreign currencies.

CORE International Equity Fund

  Objective.  This Fund seeks to provide investors with long-term growth of
  ---------                                                                
capital.  The Fund seeks to achieve its objective through a broadly diversified
portfolio of large cap equity securities of companies that are organized outside
the United States or whose securities are principally traded outside the United
States.

  Primary Investment Focus.  This Fund invests, under normal circumstances, at
  ------------------------                                                    
least 90% of its total assets in equity securities of companies that are
organized outside the United States or whose securities are principally traded
outside the United States.  The Fund seeks broad representation of large cap
issuers across major countries and sectors of the international economy.  The
Fund's investments are selected using both a variety of quantitative techniques
and fundamental research in seeking to maximize the Fund's expected return,
while maintaining risk, style, capitalization and industry characteristics
similar to the EAFE Index.  In addition, the Fund seeks a portfolio composed of
companies with attractive valuations and stronger momentum characteristics than
the EAFE Index.

  The Fund may allocate its assets among countries as determined by its
investment adviser from time to time, provided the Fund's assets are invested in
at least three foreign countries.  The Fund may invest in securities of issuers
in Emerging Countries which involve certain risks which are not present in
investments in more developed countries.

substantially all, and at least 65%, of its total assets in equity securities of
companies that are organized outside the United States or whose securities are
principally traded outside the United States.  The Fund may allocate its assets
among countries as determined by its investment adviser from time to time
provided that the Fund's assets are invested in at least three foreign
countries.  The Fund expects to invest a substantial portion of its assets in
the securities of issuers located in the developed countries of Western Europe
and in Japan.  However, the Fund may also invest in the securities of issuers
located in Australia, Canada, New Zealand and the Emerging Countries in which
the Emerging Markets Equity Fund may invest.  Many of the countries in which the
Fund may invest have emerging markets or economies which involve certain risks
that are not present in investments in more developed countries.  The Fund
intends to invest in companies with public stock market capitalizations 

                                      B-13

Emerging Markets Equity Fund

  Objective.  This Fund seeks to provide investors with long-term capital
  ---------                                                              
appreciation.

  Primary Investment Focus.  This Fund invests, under normal market
  ------------------------                                         
circumstances, substantially all, and at least 65%, of its total assets in
equity securities of Emerging Country issuers.  For purposes of the Fund's
investment policies, Emerging Countries are countries with economies or
securities markets that are considered by the Fund's investment adviser not to
be fully developed.  The investment adviser may consider classifications by the
World Bank, the International Finance Corporation or the United Nations and its
agencies in determining whether a country is emerging or developed.  Currently,
Emerging Countries include, among others, most Latin American, African, Asian
and Eastern European nations.  The Fund's investment adviser currently intends
that the Fund's investment focus will be in the following Emerging Countries:
Argentina, Botswana, Brazil, Chile, China, Colombia, the Czech Republic, Egypt,
Greece, Hong Kong, Hungary, India, Indonesia, Israel, Jordan, Kenya, Malaysia,
Mexico, Morocco, Pakistan, Peru, the Philippines, Poland, Portugal, Russia,
Singapore, South Africa, South Korea, Sri Lanka, Taiwan, Thailand, Turkey,
Venezuela and Zimbabwe.

  An Emerging Country issuer is any entity that satisfies at least one of the
following criteria: (i) it derives 50% or more of its total revenue from goods
produced, sales made or services performed in one or more Emerging Countries;
(ii) it is organized under the laws of, or has a principal office in, an
Emerging Country; (iii) it maintains 50% or more of its assets in one or more of
the Emerging Countries; or (iv) the principal securities trading market for a
class of its securities is in an Emerging Country.

  Investments in Emerging Countries involve certain risks which are not present
in investments in more developed countries.  The Fund may purchase privately
placed equity securities, equity securities of companies that are in the process
of being privatized by foreign governments, securities of issuers that have not
paid dividends on a timely basis, equity securities of issuers that have
experienced difficulties, and securities of companies without performance
records.

  Other.  Under normal circumstances, this Fund maintains investments in at
  -----                                                                    
least six Emerging Countries, and will not invest more than 35% of its total
assets in securities of issuers in any one Emerging Country.  Allocation of the
Fund's investments will depend upon the relative attractiveness of the Emerging
Country markets and particular issuers.  In addition, macro-economic factors and
the portfolio managers' and Goldman Sachs economists' views of the relative
attractiveness of Emerging Countries and currencies are considered in allocating
the Fund's assets among Emerging Countries.  Concentration of the Fund's assets
in one or a few Emerging Countries and currencies will subject the Fund to
greater risks than if the Fund's assets were not geographically concentrated.
The Fund may invest in the aggregate up to 35% of its total assets in (i) fixed-
income securities of private 

                                     B-14

and governmental Emerging Country issuers; and (ii) equity and fixed-income
securities of issuers in developed countries.

appreciation.

  Primary Investment Focus.  This Fund invests, under normal market
  ------------------------                                         
circumstances, substantially all, and at least 65%, of its total assets in
equity securities of companies that satisfy at least one of the following
criteria: (i) their securities are traded principally on stock exchanges in one
or more of the Asian countries; (ii) they derive 50% or more of their total
revenue from goods produced, sales made or services performed in one or more of
the Asian countries; (iii) they maintain 50% or more of their assets in one or
more of the Asian countries; or (iv) they are organized under the laws of one of
the Asian countries.  The Fund seeks to achieve its objective by investing
primarily in equity securities of Asian companies which are considered by the
Fund's investment adviser to have long-term capital appreciation potential.
Many of the countries in which the Fund may invest have emerging markets or
economies which involve certain risks which are not present in investments in
more developed countries.  The Fund may purchase equity securities of issuers
that have not paid dividends on a timely basis, securities of companies that
have experienced difficulties, and securities of companies without performance
records.

    
  Other.  This Fund may allocate its assets among the Asian countries as
  -----                                                                 
determined from time to time by its investment adviser.  For purposes of the
Fund's investment policies, Asian countries are China, Hong Kong, India,
Indonesia, Malaysia, Pakistan, the Philippines, Singapore, South Korea, Sri
Lanka, Taiwan and Thailand as well as any other country in Asia (other than
Japan) to the extent that foreign investors are permitted by applicable law to
make such investments.  Allocation of the Fund's investments will depend upon
the investment adviser's view of the relative attractiveness of the Asian
markets and particular issuers.  Concentration of the Fund's assets in one or a
few of the Asian countries and Asian currencies will subject the Fund to greater
risks than if the Fund's assets were not geographically concentrated.  For
example, on January 31, 1998 (the end of the Fund's last fiscal year), more than
35% of the Fund's assets were invested in securities traded in Hong Kong.  The
Fund may invest in the aggregate up to 35% of its total assets in equity
securities of issuers in other countries, including Japan, and in fixed-income
securities.

circumstances, substantially all, and at least 65%, of its total assets in
equity securities of European companies. Because of its focus, the Fund will be
more susceptible to European economic, market, political and local risks than a
fund that is more geographically diversified.  "European companies" are
companies that satisfy at least one of the following criteria: (i) their
securities are traded principally on stock exchanges in one or more of the
European countries; (ii) they derive 50% or more of their total revenue from
goods produced, sales made or services performed in one or more of the European
countries; (iii) they maintain 50% or more of their assets in one or more of the
European countries; or (iv) they are organized under the laws of a European
country.  The Fund may allocate its assets among

different countries as determined by its investment adviser, provided that the
Fund's assets are invested in at least three European countries. It is currently
anticipated that a majority of the Fund's assets will be invested in the equity
securities of large cap companies located in the developed countries of Western
Europe. However, the Fund may also invest, without limit, in mid cap companies
and small cap companies, as well as companies located in Emerging Countries in
which the Emerging Markets Equity Fund may invest, including Eastern European
countries and the European states that formerly comprised the Soviet Union and
Yugoslavia.

equity securities of non-European countries and in fixed-income securities.

Japanese Equity Fund

  Objective.  This Fund seeks to provide investors with long-term capital
  ---------

substantially all, and at least 65%, of its total assets in equity securities of
Japanese companies.  Japanese companies include those organized under the laws
of Japan or whose shares are traded primarily on a Japanese stock exchange as
well as those whose shares are registered with the Japan Securities Dealers
Association for trading primarily on Japan's over-the-counter market.  The
Fund's concentration in Japanese companies will expose it to the risk of adverse
social, political and economic events which occur in Japan or affect the
Japanese markets.

circumstances, substantially all, and at least 65%, of its total assets in
equity securities of companies with public stock market capitalizations of $1
billion or less at the time of investment that are organized outside the U.S. or
whose securities are principally traded outside the U.S. The Fund may allocate
its assets among countries as determined by its investment adviser from time to
time provided that the Fund's assets are invested in at least three foreign
countries. The Fund expects to invest a substantial portion of its assets in
small cap securities of companies in the developed countries of Western Europe,
Japan and Asia. However, the Fund may also invest in the securities of issuers
located in Australia, Canada, New Zealand and the Emerging Countries in which
the Emerging Markets Equity Fund may invest. Many of the countries in which the
Fund may invest have emerging markets economics which involve certain risks,
which are not present in investments in more developed countries. If the market
capitalization of a company held by the Fund increases above $1 billion, the
Fund may, consistent with its investment objective, continue to hold the
security.

equity securities of larger cap companies with public stock market
capitalizations of more than $1 billion at the time of investment and in fixed-
income securities.

Real Estate Securities Fund

  Objective.  This Fund seeks to provide investors with total return comprised
  ---------                                                                   
of long-term growth of capital and dividend income.

  Primary Investment Focus.  This Fund will invest, under normal circumstances,
  ------------------------                                                     
substantially all, and at least 80%, of its total assets in issuers that are
primarily engaged in or related to the real estate industry. The Fund seeks to
achieve its investment objective by investing in a diversified portfolio of
equity securities of REITs and other real estate industry companies. A "real
estate industry company" is a company that derives at least 50% of its gross
revenues or net profits from the ownership, development, construction,
financing, management or sale of commercial, industrial or residential real
estate or interests therein.

  Shares of REITs.  The Fund may invest without limitation in shares of REITs.
  ---------------                                                              
REITs are pooled investment vehicles which invest primarily in income producing
real estate or real estate related loans or interests. REITs are generally
classified as equity REITs, mortgage REITs or a combination of equity and
mortgage REITs. Equity REITs invest the majority of their assets directly in
real property and derive income primarily from the collection of rents. Equity
REITs can also realize capital gains by selling properties that have appreciated
in value. Mortgage REITs invest the majority of their assets in real estate
mortgages and derive income from the collection of interest payments. Similar to
investment companies such as the Fund, REITs are not taxed on income distributed
to shareholders provided they comply with several requirements of the Internal
Revenue Code of 1986, as amended (the "Code"). The Fund will indirectly bear its
proportionate share of expenses incurred by REITs in which the Fund invests in
addition to the expenses directly by the Fund.

total assets in fixed-income securities that, in the opinion of its investment
adviser, offer the potential to further the Fund's investment objectives.  In
addition, although the Fund will invest primarily in publicly traded U.S.
securities, it may invest up to 15% of its net assets in foreign securities.

Financial Square Prime Obligations Fund

  ---------                                                           
consistent with the preservation of capital and the maintenance of liquidity by
investing exclusively in high quality money market instruments.

  Primary Investment Focus.  This Fund invests in securities of the U.S.

Government, its agencies, authorities and instrumentalities, obligations of U.S.
banks, commercial paper, and other short-term obligations of U.S. companies,
states, municipalities and other entities and repurchase agreements.  Securities
purchased by the Fund will be determined by its investment adviser to present
minimal credit risks, and will have remaining maturities (as determined in
accordance with regulatory requirements) of 13 months or less at the time of
purchase.  The dollar-weighted average maturity of the Fund will not exceed 90
days.

money market funds as described in its Prospectus, and do not include many of
the types of investments discussed below that are permitted for the other
Underlying Funds. Although 

                                     B-17

this Fund attempts to maintain a stable net asset value of $1.00 per share,
there is no assurance that it will be able to do so on a continuous basis. Like
investments in the other Underlying Funds, an investment in this Fund is neither
insured nor guaranteed by the U.S. Government or any governmental authority.

             B.  Description of Investment Securities and Practices
                                        
Corporate Debt Obligations

    
  Each Underlying Fund (other than the Adjustable Rate Government and Short
Duration Government Funds) may, under normal market conditions, invest in
corporate debt obligations, including obligations of industrial, utility and
financial issuers.  CORE U.S. Equity, CORE  Large Cap Value Fund, CORE Large Cap
Growth,  CORE Small Cap Equity and CORE International Equity Funds may only
invest in debt securities that are cash equivalents. Corporate debt obligations
are subject to the risk of an issuer's inability to meet principal and interest
payments on the obligations and may also be subject to price volatility due to
such factors as market interest rates, market perception of the creditworthiness
of the issuer and general market liquidity.     

  Fixed-income securities rated BBB or Baa are considered medium-grade
obligations with speculative characteristics, and adverse economic conditions or
changing circumstances may weaken their issuers' capacity to pay interest and
repay principal.  Medium to lower rated and comparable non-rated securities tend
to offer higher yields than higher rated securities with the same maturities
because the historical financial condition of the issuers of such securities may
not have been as strong as that of other issuers.  Since medium to lower rated
securities generally involve greater risks of loss of income and principal than
higher rated securities, investors should consider carefully the relative risks
associated with investment in securities which carry medium to lower ratings and
in comparable unrated securities.  In addition to the risk of default, there are
the related costs of recovery on defaulted issues.  The Underlying Funds'
investment advisers will attempt to reduce these risks through portfolio
diversification and by analysis of each issuer and its ability to make timely
payments of income and principal, as well as broad economic trends and corporate
developments.

    
  High Yield Securities.  Bonds rated BB or below by Standard & Poor's Ratings
  ---------------------                                                       
Group ("Standard & Poor's") or Ba or below by Moody's Investors Service, Inc.
("Moody's") (or comparable rated and unrated securities) are commonly referred
to as "junk bonds" and are considered speculative.  The ability of their issuers
to make principal and interest payments may be questionable.  In some cases,
such bonds may be highly speculative, have poor prospects for reaching
investment grade standing and be in default.  As a result, investment in such
bonds will entail greater risks than those associated with investment grade
bonds (i.e., bonds rated AAA, AA, A or BBB by Standard and Poor's or Aaa, Aa, A
or Baa by Moody's).  Analysis of the creditworthiness of issuers of high yield
securities may be more complex than for issuers of higher quality debt
securities, and the ability of an Underlying Fund to achieve its investment
objective may, to the extent of its investments in high yield securities, be
more dependent upon such creditworthiness analysis than would be the case if the
Underlying Fund were investing in higher quality securities.  See Appendix A to
this Additional Statement for a description of the corporate bond and preferred
stock ratings by Standard & Poor's, Moody's, Fitch IBCA, Inc. and Duff & 
Phelps.     


                                     B-18
<PAGE>
 
  The amount of high yield, fixed-income securities proliferated in the 1980s
and early 1990s as a result of increased merger and acquisition and leveraged
buyout activity.  Such securities are also issued by less-established
corporations desiring to expand.  Risks associated with acquiring the securities
of such issuers generally are greater than is the case with higher rated
securities because such issuers are often less creditworthy companies or are
highly leveraged and generally less able than more established or less leveraged
entities to make scheduled payments of principal and interest.

  The market values of high yield, fixed-income securities tends to reflect
those individual corporate developments to a greater extent than do those of
higher rated securities, which react primarily to fluctuations in the general
level of interest rates.  Issuers of such high yield securities may not be able
to make use of more traditional methods of financing and their ability to
service debt obligations may be more adversely affected than issuers of higher
rated securities by economic downturns, specific corporate developments or the
issuers' inability to meet specific projected business forecasts.  These non-
investment grade securities also tend to be more sensitive to economic
conditions than higher-rated securities.  Negative publicity about the junk bond
market and investor perceptions regarding lower-rated securities, whether or not
based on fundamental analysis, may depress the prices for such securities.

  Since investors generally perceive that there are greater risks associated
with non-investment grade securities of the type in which the Underlying Funds
may invest, the yields and prices of such securities may tend to fluctuate more
than those for higher-rated securities.  In the lower quality segments of the
fixed-income securities market, changes in perceptions of issuers'
creditworthiness tend to occur more frequently and in a more pronounced manner
than do changes in higher quality segments of the fixed-income securities
market, resulting in greater yield and price volatility.

  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 an Underlying Fund's net asset value.

  The risk of loss from default for the holders of high yield, fixed-income
securities is significantly greater than is the case for holders of other debt
securities because such high yield, fixed-income securities are generally
unsecured and are often subordinated to the rights of other creditors of the
issuers of such securities.  Investment by an Underlying Fund in already
defaulted securities poses an additional risk of loss should nonpayment of
principal and interest continue in respect of such securities.  Even if such
securities are held to maturity, recovery by an Underlying Fund of its initial
investment and any anticipated income or appreciation is uncertain.  An
Underlying Fund may be required to liquidate other portfolio securities to
satisfy the Underlying Fund's annual distribution obligations in respect of
accrued interest income on securities which are subsequently written off, even
though the Underlying Fund has not received any cash payments of such interest.

  The secondary market for high yield, fixed-income securities is concentrated
in relatively few markets and is dominated by institutional investors, including
mutual funds, insurance companies and other financial institutions.
Accordingly, the secondary market for such securities is not as liquid as and is
more volatile than the secondary market for higher-

                                     B-19
<PAGE>

     
rated securities. In addition, the trading volume for high-yield, fixed-income
securities is generally lower than that of higher rated securities and the
secondary market for high yield, fixed-income securities could shrink or
disappear suddenly and without warning as a result of adverse market or economic
conditions independent of any specific adverse changes in the condition of a
particular issuer. Because of the lack of sufficient market liquidity, a Fund
may incur losses because it will be required to effect sale at a disadvantageous
time and then only at a substantial drop in price. Prices realized upon the sale
of such lower rated or unrated securities, under these circumstances, may be
less than the prices used in calculating an Underlying Fund's net asset value. A
less liquid secondary market also may make it more difficult for an Underlying
Fund to obtain precise valuations of the high yield securities in its 
portfolio.     

  Certain proposed and recently enacted federal laws could adversely affect the
secondary market for high yield securities and the financial condition of
issuers of these securities.  The form of proposed legislation and the
probability of such legislation being enacted is uncertain.

  Non-investment grade or high-yield, fixed-income securities also present risks
based on payment expectations.  High yield, fixed-income securities frequently
contain "call" or buy-back features which permit the issuer to call or
repurchase the security from its holder.  If an issuer exercises such a "call
option" and redeems the security, an Underlying Fund may have to replace such
security with a lower-yielding security, resulting in a decreased return for
investors.  In addition, if an Underlying Fund experiences net redemptions of
its shares, it may be forced to sell its higher-rated securities, resulting in a
decline in the overall credit quality of the Underlying Fund's portfolio and
increasing the exposure of the Underlying Fund to the risks of high yield
securities.  An Underlying Fund may also incur additional expenses to the extent
that it is required to seek recovery upon a default in the payment of principal
or interest on a portfolio security.

  Credit ratings issued by credit rating agencies are designed to evaluate the
safety of principal and interest payments of rated securities.  They do not,
however, evaluate the market value risk of non-investment grade securities and,
therefore, may not fully reflect the true risks of an investment.  In addition,
credit rating agencies may or may not make timely changes in a rating to reflect
changes in the economy or in the conditions of the issuer that affect the market
value of the security.  Consequently, credit ratings are used only as a
preliminary indicator of investment quality.  Investments in non-investment
grade and comparable unrated obligations will be more dependent on the credit
analysis of an Underlying Fund's investment adviser than would be the case with
investments in investment-grade debt obligations.  An Underlying Fund's
investment adviser employs its own credit research and analysis, which includes
a study of existing debt, capital structure, ability to service debt and to pay
dividends, the issuer's sensitivity to economic conditions, its operating
history and the current trend of earnings.  The investment adviser monitors the
investments in an Underlying Fund's portfolio and evaluates whether to dispose
of or to retain non-investment grade and comparable unrated securities whose
credit ratings or credit quality may have changed.

  Loan Participations.  The High Yield Fund may invest in loan participations.
  -------------------                                                          
Such loans must be to issuers in whose obligations the High Yield Fund may
invest.  A loan participation is an interest in a loan to a U.S. or foreign
company or other borrower which is administered and sold by a financial
intermediary.  In a typical corporate loan syndication, a 


                                     B-20
<PAGE>
 
number of lenders, usually banks (co-lenders), lend a corporate borrower a
specified sum pursuant to the terms and conditions of a loan agreement. One of
the co-lenders usually agrees to act as the agent bank with respect to the loan.

  Participation interests acquired by the High Yield Fund may take the form of a
direct or co-lending relationship with the corporate borrower, an assignment of
an interest in the loan by a co-lender or another participant, or a
participation in the seller's share of the loan.  When the High Yield Fund acts
as co-lender in connection with a participation interest or when the High Yield
Fund acquires certain participation interests, the High Yield Fund will have
direct recourse against the borrower if the borrower fails to pay scheduled
principal and interest.  In cases where the High Yield Fund lacks direct
recourse, it will look to the agent bank to enforce appropriate credit remedies
against the borrower.  In these cases, the High Yield Fund may be subject to
delays, expenses and risks that are greater than those that would have been
involved if the Underlying Fund had purchased a direct obligation (such as
commercial paper) of such borrower.  For example, in the event of the bankruptcy
or insolvency of the corporate borrower, a loan participation may be subject to
certain defenses by the borrower as a result of improper conduct by the agent
bank.  Moreover, under the terms of the loan participation, the High Yield Fund
may be regarded as a creditor of the agent bank (rather than of the underlying
corporate borrower), so that the High Yield Fund may also be subject to the risk
that the agent bank may become insolvent.  The secondary market, if any, for
these loan participations is limited and any loan participations purchased by
the High Yield Fund will be regarded as illiquid.

  For purposes of certain investment limitations pertaining to diversification
of the High Yield Fund's portfolio investments, the issuer of a loan
participation will be the underlying borrower.  However, in cases where the High
Yield Fund does not have recourse directly against the borrower, both the
borrower and each agent bank and co-lender interposed between the High Yield
Fund and the borrower will be deemed issuers of a loan participation.

Obligations of the United States, Its Agencies, Instrumentalities and Sponsored
Enterprises

  Each Underlying Fund may invest in U.S. government securities ("U.S.
Government Securities"), which are obligations issued or guaranteed by the U.S.
government and its agencies, instrumentalities or sponsored enterprises. Some
U.S. Government Securities (such as Treasury bills, notes and bonds, which
differ only in their interest rates, maturities and times of issuance) are
supported by the full faith and credit of the United States of America.  Others,
such as obligations issued or guaranteed by U.S. government agencies,
instrumentalities or sponsored enterprises, are supported either by (a) the
right of the issuer to borrow from the Treasury (such as securities of Federal
Home Loan Banks), (b) the discretionary authority of the U.S. government to
purchase the agency's obligations (such as securities of Federal National
Mortgage Association ("Fannie Mae")) or (c) only the credit of the issuer (such
as securities of the Financing Corporation).  The  U.S. government is under no
legal obligation, in general, to purchase the obligations of its agencies,
instrumentalities or sponsored enterprises.  No assurance can be given that the
U.S. government will provide financial support to the U.S. government agencies,
instrumentalities or sponsored enterprises in the future.


                                     B-21
<PAGE>

     
  U.S. Government Securities include (to the extent consistent with the
Investment Company Act of 1940, as amended (the "Act")) securities for which the
payment of principal and interest is backed by an irrevocable letter of credit
issued by the U.S. government, or its agencies, instrumentalities or sponsored
enterprises.  U.S. Government Securities also include (to the extent consistent
with the Act) participations in loans made to foreign governments or their
agencies that are guaranteed as to principal and interest by the U.S. government
or its agencies, instrumentalities or sponsored enterprises.  The secondary
market for certain of these participations is extremely limited.  In the absence
of a suitable secondary market, such participations are regarded as illiquid.
Each Underlying Fund may also purchase U.S. Government Securities in private
placements, subject to the Underlying Fund's limitation on investment in
illiquid securities.

  The Underlying Funds may also invest in separately traded principal and
interest components of securities guaranteed or issued by the U.S. Treasury that
are traded independently under the separate trading of registered interest and
principal of securities program ("STRIPS").     

Bank Obligations

    
  Certain of the Underlying Funds may invest in obligations issued or guaranteed
by U.S. or foreign banks.  Bank obligations, including without limitation, time
deposits, bankers' acceptances and certificates of deposit, may be general
obligations of the parent bank or may be limited to the issuing branch by the
terms of the specific obligations or government regulation.  Banks are subject
to extensive governmental regulations which may limit both the amount and types
of loans which may be made and interest rates which may be charged.  In
addition, the profitability of the banking industry is largely dependent upon
the availability and cost of funds for the purpose of financing lending
operations under prevailing money market conditions.  General economic
conditions as well as exposure to credit losses arising from possible financial
difficulties of borrowers play an important part in the operations of this
industry.     

Deferred Interest, Pay-in-Kind and Capital Appreciation Bonds

  Certain of the Underlying Funds expect to invest in deferred interest and
capital appreciation bonds and pay-in-kind ("PIK") securities.  Deferred
interest and capital appreciation bonds are debt securities issued or sold at a
discount from their face value and which do not entitle the holder to any
periodic payment of interest prior to maturity or a specified date.  The
original issue discount varies depending on the time remaining until maturity or
cash payment date, prevailing interest rates, the liquidity of the security and
the perceived credit quality of the issuer.  These securities also may take the
form of debt securities that have been stripped of their unmatured interest
coupons, the coupons themselves or receipts or certificates representing
interests in such stripped debt obligations or coupons.  The market prices of
deferred interest, capital appreciation bonds and PIK securities generally are
more volatile than the market prices of interest bearing securities and are
likely to respond to a greater degree to changes in interest rates than interest
bearing securities having similar maturities and credit quality.

  PIK securities may be debt obligations or preferred shares that provide the
issuer with the option of paying interest or dividends on such obligations in
cash or in the form of additional securities rather than cash.  Similar to zero
coupon bonds and deferred interest 


                                     B-22
<PAGE>
 
bonds, PIK securities are designed to give an issuer flexibility in managing
cash flow. PIK securities that are debt securities can either be senior or
subordinated debt and generally trade flat (i.e., without accrued interest). The
trading price of PIK debt securities generally reflects the market value of the
underlying debt plus an amount representing accrued interest since the last
interest payment.

  Deferred interest, capital appreciation and PIK securities involve the
additional risk that, unlike securities that periodically pay interest to
maturity, an Underlying Fund will realize no cash until a specified future
payment date unless a portion of such securities is sold and, if the issuer of
such securities defaults, an Underlying Fund may obtain no return at all on its
investment.  In addition, even though such securities do not provide for the
payment of current interest in cash, the Underlying Funds are nonetheless
required to accrue income on such investments for each taxable year and
generally are required to distribute such accrued amounts (net of deductible
expenses, if any) to avoid being subject to tax.  Because no cash is generally
received at the time of the accrual, an Underlying Fund may be required to
liquidate other portfolio securities to obtain sufficient cash to satisfy
federal tax distribution requirements applicable to the Underlying Fund.

Zero Coupon Bonds

  An Underlying Fund's investments in fixed-income securities may include zero
coupon bonds, which are debt obligations issued or purchased at a significant
discount from face value.  The discount approximates the total amount of
interest the bonds would have accrued and compounded over the period until
maturity.  Zero coupon bonds do not require the periodic payment of interest.
Such investments benefit the issuer by mitigating its need for cash to meet debt
service but also require a higher rate of return to attract investors who are
willing to defer receipt of such cash.  Such investments may experience greater
volatility in market value than debt obligations which provide for regular
payments of interest.  In addition, if an issuer of zero coupon bonds held by
an Underlying Fund defaults, the Underlying Fund may obtain no return at all on
its investment.  Each Fund will accrue income on such investments for each
taxable year which (net of deductible expenses, if any) is distributable to
shareholders and which, because no cash is generally received at the time of
accrual, may require the liquidation of other portfolio securities to obtain
sufficient cash to satisfy the Underlying Fund's distribution obligations.

Variable and Floating Rate Securities

  The interest rates payable on certain fixed-income securities in which an
Underlying Fund may invest are not fixed and may fluctuate based upon changes in
market rates. A variable rate obligation has an interest rate which is adjusted
at predesignated periods in response to changes in the market rate of interest
on which the interest rate is based. Variable and floating rate obligations are
less effective than fixed rate instruments at locking in a particular yield.
Nevertheless, such obligations may fluctuate in value in response to interest
rate changes if there is a delay between changes in market interest rates and
the interest reset date for the obligation.

  Permissible investments for the Underlying Funds include "leveraged" inverse
floating rate debt instruments ("inverse floaters"), including "leveraged
inverse floaters."  The interest rate on inverse floaters resets in the opposite
direction from the market rate of interest to which the inverse floater is
indexed.  An inverse floater may be considered to be

leveraged to the extent that its interest rate varies by a magnitude that
exceeds the magnitude of the change in the index rate of interest. The higher
the degree of leverage of an inverse floater, the greater the volatility of its
market value. Accordingly, the duration of an inverse floater may exceed its
stated final maturity. Certain inverse floaters may be deemed to be illiquid
securities for purposes of each Fund's limitation on illiquid investments.

Custodial Receipts

  Each Underlying Fund may invest 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
certain securities law purposes, custodial receipts are not considered U.S.
Government securities.

Municipal Securities

  Certain of the Underlying Funds may invest in bonds, notes and other
instruments issued by or on behalf of states, territories and possessions of the
United States (including the District of Columbia) and their political
subdivisions, agencies or instrumentalities ("Municipal Securities").

  Municipal Securities are often issued to obtain funds for various public
purposes including refunding outstanding obligations, obtaining funds for
general operating expenses, and obtaining funds to lend to other public
institutions and  facilities.  Municipal Securities also include certain
"private activity bonds" or industrial development bonds, which are issued by or
on behalf of public authorities to provide financing aid to acquire sites or
construct or equip facilities within a municipality for privately or publicly
owned corporations.

  The two principal classifications of Municipal Securities are "general
obligations" and "revenue obligations."  General obligations are secured by the
issuer's pledge of its full faith and credit for the payment of principal and
interest, although the characteristics and enforcement of general obligations
may vary according to the law applicable to the particular issuer.  Revenue
obligations, which include, but are  not limited to, private activity bonds,
resource recovery bonds, certificates of participation and certain municipal
notes, are not backed by the credit and taxing authority of the issuer, and are
payable solely from the revenues derived from a particular facility or class of
facilities or, in some cases, from the proceeds of a special excise or other
specific revenue source.  Nevertheless, the obligations of the issuer of a
revenue obligation may be backed by a letter of credit, guarantee or insurance.
General obligations and revenue obligations may be issued in a variety of forms,
including commercial paper, fixed, variable and floating rate securities, tender
option bonds, auction rate bonds and zero coupon bonds, deferred interest bonds
and capital appreciation bonds.

  In addition to general obligations and revenue obligations, there is a variety
of hybrid and special types of Municipal Securities.  There are also numerous
differences in the security of Municipal Securities both within and between
these two principal classifications.


                                     B-24
<PAGE>
 
  An entire issue of Municipal Securities may be purchased by one or a small
number of institutional investors such as the High Yield and Core Fixed Income
Funds.  Thus, the issue may not be said to be publicly offered.  Unlike some
securities that are not publicly offered, a secondary market exists for many
Municipal Securities that were not publicly offered initially and such
securities may be readily marketable.

  The obligations of the issuer to pay the principal of and interest on a
Municipal Security are subject to the provisions of  bankruptcy, insolvency and
other laws affecting the rights and remedies of creditors, such as the Federal
Bankruptcy Act, and laws, if any, that may be enacted by Congress or state
legislatures extending the time for payment of principal or interest or imposing
other constraints upon the enforcement of such obligations.  There is also the
possibility that, as a result of litigation or other conditions, the power or
ability of the issuer to pay when due principal of or interest on a Municipal
Security may be materially affected.

  Municipal Leases, Certificates of Participation and Other Participation
  -----------------------------------------------------------------------
Interests.  Municipal Securities include leases, certificates of participation
- ---------                                                                     
and other participation interests.  A municipal lease is an obligation in the
form of a lease or installment purchase which is issued by a state or local
government to acquire equipment and facilities.  Income from such obligations is
generally exempt from state and local taxes in the state of issuance.  Municipal
leases frequently involve special risks not normally associated with general
obligations or revenue bonds.  Leases and installment purchase or conditional
sale contracts (which normally provide for title to the leased asset to pass
eventually to the governmental issuer) have evolved as a means for governmental
issuers to acquire property and equipment without meeting the constitutional and
statutory requirements for the issuance of debt.  The debt issuance limitations
are deemed to be inapplicable because of the inclusion in many leases or
contracts of "non-appropriation" clauses that relieve the governmental issuer of
any obligation to make future payments under the lease or contract unless money
is appropriated for such purpose by the appropriate legislative body on a yearly
or other periodic basis.  In addition, such leases or contracts may be subject
to the temporary abatement of payments in the event the issuer is prevented from
maintaining occupancy of the leased premises or utilizing the leased equipment.
Although the obligations may be secured by the leased equipment or facilities,
the disposition of the property in the event of non-appropriation or foreclosure
might prove difficult, time consuming and costly, and result in a delay in
recovering or the failure to fully recover an Underlying Fund's original
investment.

  Certificates of participation represent undivided interests in municipal
leases, installment purchase agreements or other instruments.  The certificates
are typically issued by a trust or other entity which has received an assignment
of the payments to be made by the state or political subdivision under such
leases or installment purchase agreements.

  Certain municipal lease obligations and certificates of participation may be
deemed to be illiquid for the purpose of an Underlying Fund's limitation on
investments in illiquid securities.  Other municipal lease obligations and
certificates of participation acquired by an Underlying Fund may be determined
by its investment adviser, pursuant to guidelines adopted by the Trustees of the
Trust, to be liquid securities for the purpose of such limitation. In
determining the liquidity of municipal lease obligations and certificates of
participation, the investment adviser will consider a variety of factors
including: (1) the willingness of dealers to bid for the security; (2) the
number of dealers willing to purchase or sell the 


                                     B-25
<PAGE>
 
obligation and the number of other potential buyers; (3) the frequency of trades
or quotes for the obligation; and (4) the nature of the marketplace trades. In
addition, the investment adviser will consider factors unique to particular
lease obligations and certificates of participation affecting the marketability
thereof. These include the general creditworthiness of the issuer, the
importance to the issuer of the property covered by the lease and the likelihood
that the marketability of the obligation will be maintained throughout the time
the obligation is held by an Underlying Fund.

  The Underlying Funds may purchase participations in Municipal Securities held
by a commercial bank or other financial institution. Such participations provide
an Underlying Fund with the right to a pro rata undivided interest in the
underlying Municipal Securities. In addition, such participations generally
provide an Underlying Fund with the right to demand payment, on not more than
seven days' notice, of all or any part of such Fund's participation interest in
the underlying Municipal Security, plus accrued interest. An Underlying Fund
will only invest in such participations if, in the opinion of bond counsel,
counsel for the issuers of such participations or counsel selected by the
investment advisors, the interest from such participation is exempt from regular
federal income tax.

  Auction Rate Securities.  Municipal Securities also include auction rate
  -----------------------                                                 
Municipal Securities and auction rate preferred securities issued by closed-end
investment companies that invest primarily in Municipal Securities
(collectively, "auction rate securities").  Provided that the auction mechanism
is successful, auction rate securities usually permit the holder to sell the
securities in an auction at par value at specified intervals.  The dividend is
reset by "Dutch" auction in which bids are made by broker-dealers and other
institutions for a certain amount of securities at a specified minimum yield.
The dividend rate set by the auction is the lowest interest or dividend rate
that covers all securities offered for sale.  While this process is designed to
permit auction rate securities to be traded at par value, there is some risk
that an auction will fail due to insufficient demand for the securities.

  An Underlying Fund's investments in auction rate securities of closed-end
funds are subject to the limitations prescribed by the Act.  An Underlying Fund
will indirectly bear its proportionate share of any management and other fees
paid by such closed-end funds in addition to the advisory fees payable directly
by the Underlying Funds.

  Other Types of Municipal Securities.  Other types of Municipal Securities in
  -----------------------------------                                         
which certain of the Underlying Funds may invest include municipal notes, tax-
exempt commercial paper, pre-refunded municipal bonds, industrial development
bonds and insured municipal obligations.

  Call Risk and Reinvestment Risk.  Municipal Securities may include "call"
  -------------------------------                                          
provisions which permit the issuers of such securities, at any time or after a
specified period, to redeem the securities prior to their stated maturity.  In
the event that Municipal Securities held in an Underlying Fund's portfolio are
called prior to the maturity, the Underlying Fund will be required to reinvest
the proceeds on such securities at an earlier date and may be able to do so only
at lower yields, thereby reducing the Underlying Fund's return on its portfolio
securities.

Mortgage Loans and Mortgage-Backed Securities

  General Characteristics.  Certain of the Underlying Funds may invest in
  -----------------------                                                
Mortgage-Backed Securities as described in the Prospectus.  Each mortgage pool
underlying Mortgage-Backed Securities consists of mortgage loans evidenced by
promissory notes secured by first mortgages or first deeds of trust or other
similar security instruments creating a first lien on owner occupied and non-
owner occupied one-unit to four-unit residential properties, multifamily (i.e.,
five or more) properties, agriculture properties, commercial properties and
mixed use properties (the "Mortgaged Properties"). The Mortgaged Properties may
consist of detached individual dwelling units, multifamily dwelling units,
individual condominiums, townhouses, duplexes, triplexes, fourplexes, row
houses, individual units in planned unit developments and other attached
dwelling units. The Mortgaged Properties may also include residential investment
properties and second homes.

  The investment characteristics of adjustable and fixed rate Mortgage-Backed
Securities differ from those of traditional fixed-income securities.  The major
differences include the payment of interest and principal on Mortgage-Backed
Securities on a more frequent (usually monthly) schedule, and the possibility
that principal may be prepaid at any time due to prepayments on the underlying
mortgage loans or other assets.  These differences can result in significantly
greater price and yield volatility than is the case with traditional fixed-
income securities.  As a result, if an Underlying Fund purchases Mortgage-Backed
Securities at a premium, a faster than expected prepayment rate will reduce both
the market value and the yield to maturity from those which were anticipated.  A
prepayment rate that is slower than expected will have the opposite effect of
increasing yield to maturity and market value.  Conversely, if an Underlying
Fund purchases Mortgage-Backed Securities at a discount, faster than expected
prepayments will increase, while slower than expected prepayments will reduce
yield to maturity and market values.  To the extent that an Underlying Fund
invests in Mortgage-Backed Securities, its investment adviser may seek to manage
these potential risks by investing in a variety of Mortgage-Backed Securities
and by using certain hedging techniques.

    
  Adjustable Rate Mortgage Loans ("ARMs").  ARMs generally provide for a fixed
  ---------------------------------------                                     
initial mortgage interest rate for a specified period of time. Thereafter, the
interest rates (the "Mortgage Interest Rates") may be subject to periodic
adjustment based on changes in the applicable index rate (the "Index Rate"). The
adjusted rate would be equal to the Index Rate plus a fixed percentage spread
over the Index Rate established for each ARM at the time of its origination.
ARMs allow a Fund to participate in increases in interest rates through periodic
increases in the securities coupon rates. During periods of declining interest
rates, coupon rates may readjust downward resulting in lower yields to a 
Fund.     

  Adjustable interest rates can cause payment increases that some mortgagors may
find difficult to make.  However, certain ARMs may provide that the Mortgage
Interest Rate may not be adjusted to a rate above an applicable lifetime maximum
rate or below an applicable lifetime minimum rate for such ARM.  Certain ARMs
may also be subject to limitations on the maximum amount by which the Mortgage
Interest Rate may adjust for any single adjustment period (the "Maximum
Adjustment").  Other ARMs ("Negatively Amortizing  ARMs") may provide instead or
as well for limitations on changes in the monthly payment on such ARMs.
Limitations on monthly payments can result in monthly payments which are greater
or less than the amount necessary to amortize a Negatively Amortizing ARM by its
maturity at the Mortgage Interest Rate in effect in any particular month.  In
the event that a 


                                     B-27
<PAGE>
 
monthly payment is not sufficient to pay the interest accruing on a Negatively
Amortizing ARM, any such excess interest is added to the principal balance of
the loan, causing negative amortization, and will be repaid through future
monthly payments. It may take borrowers under Negatively Amortizing ARMs longer
periods of time to build up equity and may increase the likelihood of default by
such borrowers. In the event that a monthly payment exceeds the sum of the
interest accrued at the applicable Mortgage Interest Rate and the principal
payment which would have been necessary to amortize the outstanding principal
balance over the remaining term of the loan, the excess (or "accelerated
amortization") further reduces the principal balance of the ARM. Negatively
Amortizing ARMs do not provide for the extension of their original maturity to
accommodate changes in their Mortgage Interest Rate. As a result, unless there
is a periodic recalculation of the payment amount (which there generally is),
the final payment may be substantially larger than the other payments. These
limitations on periodic increases in interest rates and on changes in monthly
payments protect borrowers from unlimited interest rate and payment increases.

    
  ARMs also have the risk of prepayments. The rate of principal prepayments with
respect to ARMs has fluctuated in recent years. As with fixed-rate mortgage
loans, ARMs may be subject to a greater rate of principal repayments in a
declining interest rate environment resulting in lower yields to a Fund. For
example, if prevailing interest rates fall significantly, ARMs could be subject
to higher prepayment rates (than if prevailing interest rates remain constant or
increase) because the availability of low fixed-rate mortgages may encourage
mortgagors to refinance their ARMs to "lock-in" a fixed-rate mortgage.
Conversely, if prevailing interest rates rise significantly, ARMs may prepay
more slowly. As with fixed-rate mortgages, ARM prepayment rates vary in both
stable and changing interest rate environments.     

  There are two main categories of indices which provide the basis for rate
adjustments on ARMs: those based on U.S. Treasury securities and those derived
from a calculated measure, such as a cost of funds index or a moving average of
mortgage rates. Commonly utilized indices include the one-year, three-year and
five-year constant maturity Treasury rates, the three-month Treasury bill rate,
the 180-day Treasury bill rate, rates on longer-term Treasury securities, the
11th District Federal Home Loan Bank Cost of Funds, the National Median Cost of
Funds, the one-month, three-month, six-month or one-year London Interbank
Offered Rate, the prime rate of a specific bank or commercial paper rates. Some
indices, such as the one-year constant maturity Treasury rate, closely mirror
changes in market interest rate levels. Others, such as the 11th District
Federal Home Loan Bank Cost of Funds index, tend to lag behind changes in market
rate levels and tend to be somewhat less volatile. The degree of volatility in
the market value of an Underlying Fund's portfolio and, therefore, in the net
asset value of an Underlying Fund's shares will be a function of the length of
the interest rate reset periods and the degree of volatility in the applicable
indices.

  Fixed-Rate Mortgage Loans.  Generally, fixed-rate mortgage loans included in a
  -------------------------                                                     
mortgage pool (the "Fixed-Rate Mortgage Loans") will bear simple interest at
fixed annual rates and have original terms to maturity ranging from 5 to 40
years. Fixed-Rate Mortgage Loans generally provide for monthly payments of
principal and interest in substantially equal installments for the term of the
mortgage note in sufficient amounts to fully amortize principal by maturity,
although certain Fixed-Rate Mortgage Loans provide for a large final "balloon"
payment upon maturity.

                                     B-28
<PAGE>
 
  Legal Considerations of Mortgage Loans.  The following is a discussion of
  --------------------------------------                                   
certain legal and regulatory aspects of the mortgage loans in which the
Underlying Funds may invest. These regulations may impair the ability of a
mortgage lender to enforce its rights under the mortgage documents. These
regulations may adversely affect the Underlying Funds' investments in Mortgage-
Backed Securities (including those issued or guaranteed by the U.S. government,
its agencies or instrumentalities) by delaying the Underlying Funds' receipt of
payments derived from principal or interest on mortgage loans affected by such
regulations.

1.   Foreclosure.  A foreclosure of a defaulted mortgage loan may be delayed due
     -----------                                                                
     to compliance with statutory notice or service of process provisions,
     difficulties in locating necessary parties or legal challenges to the
     mortgagee's right to foreclose.  Depending upon market conditions, the
     ultimate proceeds of the sale of foreclosed property may not equal the
     amounts owed on the Mortgage-Backed Securities.

     Furthermore, courts in some cases have imposed general equitable principles
     upon foreclosure generally designed to relieve the borrower from the legal
     effect of default and have required lenders to undertake affirmative and
     expensive actions to determine the causes for the default and the
     likelihood of loan reinstatement.

2.   Rights of Redemption.  In some states, after foreclosure of a mortgage
     --------------------                                                  
     loan, the borrower and foreclosed junior lienors are given a statutory
     period in which to redeem the property, which right may diminish the
     mortgagee's ability to sell the property.

3.   Legislative Limitations.  In addition to anti-deficiency and related
     -----------------------                                             
     legislation, numerous other federal and state statutory provisions,
     including the federal bankruptcy laws and state laws affording relief to
     debtors, may interfere with or affect the ability of a secured mortgage
     lender to enforce its security interest. For example, a bankruptcy court
     may grant the debtor a reasonable time to cure a default on a mortgage
     loan, including a payment default. The court in certain instances may also
     reduce the monthly payments due under such mortgage loan, change the rate
     of interest, reduce the principal balance of the loan to the then-current
     appraised value of the related mortgaged property, alter the mortgage loan
     repayment schedule and grant priority of certain liens over the lien of the
     mortgage loan. If a court relieves a borrower's obligation to repay amounts
     otherwise due on a mortgage loan, the mortgage loan servicer will not be
     required to advance such amounts, and any loss may be borne by the holders
     of securities backed by such loans. In addition, numerous federal and state
     consumer protection laws impose penalties for failure to comply with
     specific requirements in connection with origination and servicing of
     mortgage loans.

4.   "Due-on-Sale" Provisions.  Fixed-rate mortgage loans may contain a so-
     ------------------------                                             
     called "due-on-sale" clause permitting acceleration of the maturity of the
     mortgage loan if the borrower transfers the property. The Garn-St. Germain
     Depository Institutions Act of 1982 sets forth nine specific instances in
     which no mortgage lender covered by that Act may exercise a "due-on-sale"
     clause upon a transfer of property. The inability to enforce a "due-on-
     sale" clause or the lack of such a clause in mortgage loan documents may
     result in a mortgage loan being assumed by a purchaser of the property that
     bears an interest rate below the current market rate.

                                     B-29
<PAGE>
 
5.   Usury Laws.  Some states prohibit charging interest on mortgage loans in
     ----------                                                              
     excess of statutory limits. If such limits are exceeded, substantial
     penalties may be incurred and, in some cases, enforceability of the
     obligation to pay principal and interest may be affected.

    
  Government Guaranteed Mortgage-Backed Securities.  There are several types of
  ------------------------------------------------                             
guaranteed Mortgage-Backed Securities currently available, including guaranteed
mortgage pass-through certificates and multiple class securities, which include
guaranteed Real Estate Mortgage Investment Conduit Certificates ("REMIC
Certificates"), collateralized mortgage obligations and stripped Mortgage-Backed
Securities.  An Underlying Fund is permitted to invest in other types of
Mortgage-Backed Securities that may be available in the future to the extent
consistent with its investment policies and objective.

  An Underlying Fund's investments in Mortgage-Backed Securities may include
securities issued or guaranteed by the U.S. Government or one of its agencies,
authorities, instrumentalities or sponsored enterprises, such as the Government
National Mortgage Association ("Ginnie Mae"), the Federal National Mortgage
Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation
("Freddie Mac").     

  Ginnie Mae Certificates.  Ginnie Mae is a wholly-owned corporate
  -----------------------                                         
instrumentality of the United States.  Ginnie Mae is authorized to guarantee the
timely payment of the principal of and interest on certificates that are based
on and backed by a pool of mortgage loans insured by the Federal Housing
Administration ("FHA Loans"), or guaranteed by the Veterans Administration ("VA
Loans"), or by pools of other eligible mortgage loans.  In order to meet its
obligations under any guaranty, Ginnie Mae is authorized to borrow from the
United States Treasury in an unlimited amount.

  Fannie Mae Certificates.  Fannie Mae is a stockholder-owned corporation
  -----------------------                                                
chartered under an act of the United States Congress. Each Fannie Mae
Certificate is issued and guaranteed by Fannie Mae and represents an undivided
interest in a pool of mortgage loans (a "Pool") formed by Fannie Mae. Each Pool
consists of residential mortgage loans ("Mortgage Loans") either previously
owned by Fannie Mae or purchased by it in connection with the formation of the
Pool. The Mortgage Loans may be either conventional Mortgage Loans (i.e., not
insured or guaranteed by any U.S. Government agency) or Mortgage Loans that are
either insured by the FHA or guaranteed by the Veterans Administration ("VA").
However, the Mortgage Loans in Fannie Mae Pools are primarily conventional
Mortgage Loans. The lenders originating and servicing the Mortgage Loans are
subject to certain eligibility requirements established by Fannie Mae.

  Fannie Mae has certain contractual responsibilities. With respect to each
Pool, Fannie Mae is obligated to distribute scheduled monthly installments of
principal and interest after Fannie Mae's servicing and guaranty fee, whether or
not received, to Certificate holders. Fannie Mae also is obligated to distribute
to holders of Certificates an amount equal to the full principal balance of any
foreclosed Mortgage Loan, whether or not such principal balance is actually
recovered. The obligations of Fannie Mae under its guaranty of the Fannie Mae
Certificates are obligations solely of Fannie Mae.

  Freddie Mac Certificates.  Freddie Mac is a publicly held U.S. Government
  ------------------------                                                 
sponsored enterprise. The principal activity of Freddie Mac currently is the
purchase of first

                                     B-30
<PAGE>
 
lien, conventional, residential mortgage loans and participation interests in
such mortgage loans and their resale in the form of mortgage securities,
primarily Freddie Mac Certificates. A Freddie Mac Certificate represents a pro
rata interest in a group of mortgage loans or participation in mortgage loans (a
"Freddie Mac Certificate group") purchased by Freddie Mac.

  Freddie Mac guarantees to each registered holder of a Freddie Mac Certificate
the timely payment of interest at the rate provided for by such Freddie Mac
Certificate (whether or not received on the underlying loans).  Freddie Mac also
guarantees to each registered Certificate holder ultimate collection of all
principal of the related mortgage loans, without any offset or deduction, but
does not, generally, guarantee the timely payment of scheduled principal.  The
obligations of Freddie Mac under its guaranty of Freddie Mac Certificates are
obligations solely of Freddie Mac.

  The mortgage loans underlying the Freddie Mac and Fannie Mae Certificates
consist of adjustable rate or fixed rate mortgage loans with original terms to
maturity of between five and thirty years.  Substantially all of these mortgage
loans are secured by first liens on one-to-four-family residential properties or
multifamily projects.  Each mortgage loan must meet the applicable standards set
forth in the law creating Freddie Mac or Fannie Mae.  A Freddie Mac Certificate
group may include whole loans, participation interests in whole loans, undivided
interests in whole loans and participations comprising another Freddie Mac
Certificate group.

  Conventional Mortgage Loans.  The conventional mortgage loans underlying the
  ---------------------------                                                 
Freddie Mac and Fannie Mae Certificates consist of adjustable rate or fixed-rate
mortgage loans with original terms to maturity of between five and thirty years.
Substantially all of these mortgage loans are secured by first liens on one- to
four-family residential properties or multi-family projects.  Each mortgage loan
must meet the applicable standards set forth in the law creating Freddie Mac or
Fannie Mae.  A Freddie Mac Certificate group may include whole loans,
participation interests in whole loans, undivided interests in whole loans and
participations comprising another Freddie Mac Certificate group.

    
  Mortgage Pass-Through Securities.  As described in the Prospectus, the
  --------------------------------                                      
Underlying Funds may invest in both government guaranteed and privately issued
mortgage pass-through securities ("Mortgage Pass-Throughs"); that is, fixed or
adjustable rate Mortgage-Backed Securities which provide for monthly payments
that are a "pass-through" of the monthly interest and principal payments
(including any prepayments) made by the individual borrowers on the pooled
mortgage loans, net of any fees or other amounts paid to any guarantor,
administrator and/or servicer of the underlying mortgage loans.     

  The following discussion describes only a few of the wide variety of
structures of Mortgage Pass-Throughs that are available or may be issued.

  Description of Certificates.  Mortgage Pass-Throughs may be issued in one or
  ---------------------------                                                 
more classes of senior certificates and one or more classes of subordinate
certificates.  Each such class may bear a different pass-through rate.
Generally, each certificate will evidence the specified interest of the holder
thereof in the  payments of principal or interest or both in respect of the
mortgage pool comprising part of the trust fund for such certificates.

                                     B-31
<PAGE>
 
  Any class of certificates may also be divided into subclasses entitled to
varying amounts of principal and interest.  If a REMIC election has been made,
certificates of such subclasses may be entitled to payments on the basis of a
stated principal balance and stated interest rate, and payments among different
subclasses may be made on a sequential, concurrent, pro rata or disproportionate
basis, or any combination thereof.  The stated interest rate on any such
subclass of certificates may be a fixed rate or one which varies in direct or
inverse relationship to an objective interest index.

  Generally, each registered holder of a certificate will be entitled to receive
its pro rata share of monthly distributions of all or a portion of principal of
the underlying mortgage loans or of interest on the principal balances thereof,
which accrues at the applicable mortgage pass-through rate, or both.  The
difference between the mortgage interest rate and the related mortgage pass-
through rate (less the amount, if any, of retained yield) with respect to each
mortgage loan will generally be paid to the servicer as a servicing fee.  Since
certain adjustable rate mortgage loans included in a mortgage pool may provide
for deferred interest (i.e., negative amortization), the amount of interest
actually paid by a mortgagor in any month may be less than the amount of
interest accrued on the outstanding principal balance of the related mortgage
loan during the relevant period at the applicable mortgage interest rate.  In
such event, the amount of interest that is treated as deferred interest will be
added to the principal balance of the related mortgage loan and will be
distributed pro rata to certificate-holders as principal of such mortgage loan
when paid by the mortgagor in subsequent monthly payments or at maturity.

  Ratings.  The ratings assigned by a rating organization to Mortgage Pass-
  -------                                                                 
Throughs address the likelihood of the receipt of all distributions on the
underlying mortgage loans by the related certificate-holders under the
agreements  pursuant to which such certificates are issued.  A rating
organization's ratings take into consideration the credit quality of the related
mortgage pool, including any credit support providers, structural and legal
aspects associated with such certificates, and the extent to which the payment
stream on such mortgage pool is adequate to make payments required by such
certificates.  A rating organization's ratings on such certificates do not,
however, constitute a statement regarding frequency of prepayments on the
related mortgage loans.  In addition, the rating assigned by a rating
organization to a certificate does not address the remote  possibility that, in
the event of the insolvency of the issuer of certificates where a subordinated
interest was retained, the issuance and sale of the senior certificates may 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 

                                     B-32
<PAGE>
 
receive any or a specified portion of distributions with respect to the
underlying mortgage loans may be subordinated to the rights of the senior
certificate-holders. If so structured, the subordination feature may be enhanced
by distributing to the senior certificate-holders on certain distribution dates,
as payment of principal, a specified percentage (which generally declines over
time) of all principal payments received during the preceding prepayment period
("shifting interest credit enhancement"). This will have the effect of
accelerating the amortization of the senior certificates while increasing the
interest in the trust fund evidenced by the subordinate certificates. Increasing
the interest of the subordinate certificates relative to that of the senior
certificates is intended to preserve the availability of the subordination
provided by the subordinate certificates. In addition, because the senior
certificate-holders in a shifting interest credit enhancement structure are
entitled to receive a percentage of principal prepayments which is greater than
their proportionate interest in the trust fund, the rate of principal
prepayments on the mortgage loans will have an even greater effect on the rate
of principal payments and the amount of interest payments on, and the yield to
maturity of, the senior certificates.

  In addition to providing for a preferential right of the senior certificate-
holders to receive current distributions from the mortgage pool, a reserve fund
may be established relating to such certificates (the "Reserve Fund").  The
Reserve Fund may be created with an initial cash deposit by the originator or
servicer and augmented by the retention of distributions otherwise available to
the subordinate certificate-holders or by excess servicing fees until the
Reserve Fund reaches a specified amount.

  The subordination feature, and any Reserve Fund, are intended to enhance the
likelihood of timely receipt by senior certificate-holders of the full amount of
scheduled monthly payments of principal and interest due them and will protect
the senior certificate-holders against certain losses; however, in certain
circumstances the Reserve Fund could be depleted and temporary shortfalls could
result.  In the event the Reserve Fund is depleted before the subordinated
amount is reduced to zero, senior certificate-holders will nevertheless have a
preferential right to receive current distributions from the mortgage pool to
the extent of the then outstanding subordinated amount.  Unless otherwise
specified, until the subordinated amount is reduced to zero, on any distribution
date any amount otherwise distributable to the subordinate certificates or, to
the extent specified, in the Reserve Fund will generally be used to offset the
amount of any losses realized with respect to the mortgage loans ("Realized
Losses").  Realized Losses remaining after application of such amounts will
generally be applied to reduce the ownership interest of the subordinate
certificates in the mortgage pool.  If the subordinated amount has been reduced
to zero, Realized Losses generally will be allocated pro rata among all
certificate-holders in proportion to their respective outstanding interests in
the mortgage pool.

  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

                                     B-33
<PAGE>
 
advances of cash for the benefit of certificate-holders, but only to the extent
that it determines such voluntary advances will be recoverable from future
payments and collections on the mortgage loans or otherwise.

  Optional Termination.  Generally, the servicer may, at its option with respect
  --------------------                                                          
to any certificates, repurchase all of the underlying mortgage loans remaining
outstanding at such time as the aggregate outstanding principal balance of such
mortgage loans is less than a specified percentage (generally 5-10%) of the
aggregate outstanding principal balance of the mortgage loans as of the cut-off
date specified with respect to such series.

    
  Multiple Class Mortgage-Backed Securities and Collateralized Mortgage
  ---------------------------------------------------------------------
Obligations.  An Underlying Fund may invest in multiple class securities
- -----------                                                             
including collateralized mortgage obligations ("CMOs") and REMIC Certificates.
These securities may be issued by U.S. Government agencies and instrumentalities
such as Fannie Mae or Freddie Mac or by trusts formed by private originators of,
or investors in, mortgage loans, including savings and loan associations,
mortgage bankers, commercial banks, insurance companies, investment banks and
special purpose subsidiaries of the foregoing.  In general, CMOs are debt
obligations of a legal entity that are collateralized by, and multiple class
Mortgage-Backed Securities represent direct ownership interests in, a pool of
mortgage loans or Mortgage-Backed Securities the payments on which are used to
make payments on the CMOs or multiple class Mortgage-Backed Securities.     

  Fannie Mae REMIC Certificates are issued and guaranteed as to timely
distribution of principal and interest by Fannie Mae.  In addition, Fannie Mae
will be obligated to distribute the principal balance of each class of REMIC
Certificates in full, whether or not sufficient funds are otherwise available.

  Freddie Mac guarantees the timely payment of interest on Freddie Mac REMIC
Certificates and also guarantees the payment of principal as payments are
required to be made on the underlying mortgage participation certificates
("PCs").  PCs represent undivided interests in specified level payment,
residential mortgages or participations therein purchased by Freddie Mac and
placed in a PC pool.  With respect to principal payments on PCs, Freddie Mac
generally guarantees ultimate collection of all principal of the related
mortgage loans without offset or deduction.  Freddie Mac also guarantees timely
payment of principal of certain PCs.

    
  CMOs and guaranteed REMIC Certificates issued by Fannie Mae and Freddie Mac
are types of multiple class Mortgage-Backed Securities.  Investors may purchase
beneficial interests in REMICs, which are known as "regular" interests or
"residual" interests. The Underlying Funds do not intend to purchase residual
interests in REMICs.  The REMIC Certificates represent beneficial ownership
interests in a REMIC trust, generally consisting of mortgage loans or Fannie
Mae, Freddie Mac or Ginnie Mae guaranteed Mortgage-Backed Securities (the
"Mortgage Assets").  The obligations of Fannie Mae or Freddie Mac under their
respective guaranty of the REMIC Certificates are obligations solely of Fannie
Mae or Freddie Mac, respectively.     

  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 

                                     B-34
<PAGE>
 
REMIC Certificates may cause some or all of the classes of CMOs or REMIC
Certificates to be retired substantially earlier than their final distribution
dates. Generally, interest is paid or accrues on all classes of CMOs or REMIC
Certificates on a monthly basis.

  The principal of and interest on the Mortgage Assets may be allocated among
the several classes of CMOs or REMIC Certificates in various ways.  In certain
structures (known as "sequential pay" CMOs or REMIC Certificates),  payments of
principal, including any principal prepayments, on the Mortgage Assets generally
are applied to the classes of CMOs or REMIC Certificates in the order of their
respective final distribution dates.  Thus, no payment of principal will be made
on any class of sequential pay CMOs or REMIC Certificates until all other
classes having an earlier final distribution date have been paid in full.

  Additional structures of CMOs and REMIC Certificates include, among others,
"parallel pay" CMOs and REMIC Certificates.  Parallel pay CMOs or REMIC
Certificates are those which are structured to apply principal payments and
prepayments of the Mortgage Assets to two or more classes concurrently on a
proportionate or disproportionate basis.  These simultaneous payments are taken
into account in calculating the final distribution date of each class.

  A wide variety of REMIC Certificates may be issued in parallel pay or
sequential pay structures.  These securities include accrual certificates (also
known as "Z-Bonds"), which only accrue interest at a specified rate until all
other certificates having an earlier final distribution date have been retired
and are converted thereafter to an interest-paying security, and planned
amortization class ("PAC") certificates, which are parallel pay REMIC
Certificates that generally require that specified amounts of principal be
applied on each payment date to one or more classes or REMIC Certificates (the
"PAC Certificates"), even though all other principal payments and prepayments of
the Mortgage Assets are then required to be applied to one or more other classes
of the Certificates.  The scheduled principal payments for the PAC Certificates
generally have the highest  priority on each payment date after interest due has
been paid to all classes entitled to receive interest currently.  Shortfalls, if
any, are added to the amount payable on the next payment date. The PAC
Certificate payment schedule is taken into account in calculating the final
distribution date of each class of PAC.  In order to create PAC tranches, one or
more tranches generally must be created that absorb most of the volatility in
the underlying mortgage assets.  These tranches tend to have market prices and
yields that are much more volatile than other PAC classes.

  Stripped Mortgage-Backed Securities.  Certain of the Underlying Funds may
  -----------------------------------                                      
invest in stripped mortgage-backed securities ("SMBS"), which are derivative
multiclass mortgage securities, issued or guaranteed by the U.S. Government, its
agencies or instrumentalities or by private issuers.  Although the market for
such securities is increasingly liquid, privately issued SMBS may not be readily
marketable and will be considered illiquid for purposes of an Underlying Fund's
limitation on investments in illiquid securities.  An Underlying Fund's
investment adviser may determine that SMBS which are U.S. Government Securities
are liquid for purposes of each Fund's limitation on investments in illiquid
securities.  The market value of the class consisting entirely of principal
payments generally is unusually volatile in response to changes in interest
rates.  The yields on a class of SMBS that receives all or most of the interest
from Mortgage Assets are generally higher than prevailing market 

                                     B-35
<PAGE>
 
yields on other Mortgage-Backed Securities because their cash flow patterns are
more volatile and there is a greater risk that the initial investment will not
be fully recouped.

Asset-Backed Securities

  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.  During
periods of declining interest rates, prepayment of loans underlying asset-backed
securities can be expected to accelerate.  Accordingly, an Underlying Fund's
ability to maintain positions in such securities will be affected by reductions
in the principal amount of such securities resulting from prepayments, and its
ability to reinvest the returns of principal at comparable yields is subject to
generally prevailing interest rates at that time.  To the extent that an
Underlying Fund invests in asset-backed securities, the values of such Fund's
portfolio securities will vary with changes in market interest rates generally
and the differentials in yields among various kinds of asset-backed securities.

  Asset-backed securities present certain additional risks that are not
presented by Mortgage-Backed Securities because asset-backed securities
generally do not have the benefit of a security interest in collateral that is
comparable to Mortgage Assets. Credit card receivables are generally unsecured
and the debtors on such receivables are entitled to the protection of a number
of state and federal consumer credit laws, many of which give such debtors the
right to set-off certain amounts owed on the credit cards, thereby reducing the
balance due.  Automobile receivables generally are secured, but by automobiles
rather than residential real property.  Most issuers of automobile receivables
permit the loan servicers to retain possession of the underlying obligations.
If the servicer were to sell these obligations to  another party, there is a
risk that the purchaser would acquire an interest superior to that of the
holders of the asset-backed securities.  In addition, because of the large
number of vehicles involved in a typical issuance and technical requirements
under state laws, the trustee for the holders of the automobile receivables may
not have a proper security interest in the underlying automobiles.  Therefore,
there is the possibility that, in some cases, recoveries on repossessed
collateral may not be available to support payments on these securities.

Futures Contracts and Options on Futures Contracts

    
  Each Underlying Fund (other than Financial Square Prime Obligations Fund) may
purchase and sell futures contracts and may also purchase and write options on
futures contracts.  CORE Large Cap Value and CORE Large Cap Growth Funds may
only enter into such transactions with respect to a representative index.  CORE
U.S. Equity Fund may enter into futures transactions only with respect to the
S&P 500 Index.  The other      

                                     B-36
<PAGE>
 
Funds may purchase and sell futures contracts based on various securities (such
as U.S. Government securities), securities indices, foreign currencies and other
financial instruments and indices. An Underlying Fund will engage in futures and
related options transactions, only for bona fide hedging purposes as defined
below or for purposes of seeking to increase total return to the extent
permitted by regulations of the Commodity Futures Trading Commission ("CFTC").
Futures contracts entered into by an Underlying Fund are traded on U.S.
exchanges or boards of trade that are licensed and regulated by the CFTC or on
foreign exchanges. Neither the CFTC, National Futures Association nor any
domestic exchange regulates activities of any foreign exchange or boards of
trade, including the execution, delivery and clearing of transactions, or has
the power to compel enforcement of the rules of a foreign exchange or board of
trade or any applicable foreign law. This is true even if the exchange is
formally linked to a domestic market so that a position taken on the market may
be liquidated by a transaction on another market. Moreover, such laws or
regulations will vary depending on the foreign country in which the foreign
futures or foreign options transaction occurs. For these reasons, persons who
trade foreign futures or foreign options contracts may not be afforded certain
of the protective measures provided by the Commodity Exchange Act, the CFTC's
regulations and the rules of the National Futures Association and any domestic
exchange, including the right to use reparations proceedings before the CFTC and
arbitration proceedings provided by the National Futures Association or any
domestic futures exchange. In particular, an Underlying Fund's investments in
foreign futures or foreign options transactions may not be provided the same
protections in respect of transactions on United States futures exchanges.

  Futures Contracts.  A futures contract may generally be described as an
  -----------------                                                      
agreement between two parties to buy and sell particular financial instruments
or currencies for an agreed price during a designated month (or to deliver the
final cash settlement price, in the case of a contract relating to an index or
otherwise not calling for physical delivery at the end of trading in the
contract).

    
  When interest rates are rising or securities prices are falling, an Underlying
Fund can seek through the sale of futures contracts to offset a decline in the
value of its current portfolio securities.  When rates are falling or prices are
rising, an Underlying Fund, through the purchase of futures contracts, can
attempt to secure better rates or prices than might later be available in the
market when it effects anticipated purchases.  Similarly, an Underlying Fund may
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, or purchase futures contracts on foreign currency
to establish the price in U.S. dollars of a security quoted or denominated in
such currency that such Fund has acquired or expects to acquire.  The Underlying
Fixed-Income Funds may also use futures contracts to manage their term
structure, sector selection and duration in accordance with their investment
objectives and policies.     

  Positions taken in the futures market are not normally held to maturity, but
are instead liquidated through offsetting transactions which may result in a
profit or a loss.  While an Underlying Fund will usually liquidate futures
contracts on securities or currency in this manner, an Underlying Fund may
instead make or take delivery of the underlying securities or currency whenever
it appears economically advantageous for the Underlying Fund to do so.  A
clearing corporation associated with the exchange on which futures are traded
guarantees that, if still open, the sale or purchase will be performed on the
settlement date.

                                     B-37
<PAGE>
 
  Hedging Strategies.  Hedging, by use of futures contracts, seeks to establish
  ------------------                                                           
with more certainty than would otherwise be possible the effective price, rate
of return or currency exchange rate on portfolio securities or securities that
an Underlying Fund owns or proposes to acquire.  An Underlying Fund may, for
example, take a "short" position in the futures market by selling futures
contracts to seek to hedge against an anticipated rise in interest rates or a
decline in market prices or foreign currency rates that would adversely affect
the dollar value of such Fund's portfolio securities.  Similarly, an Underlying
Fund may sell futures contracts on a currency in which its portfolio securities
are quoted or denominated or in one currency to seek to hedge against
fluctuations in the value of securities quoted or denominated in a different
currency if there is an established historical pattern of correlation between
the two currencies.  If, in the opinion of an Underlying Fund's investment
adviser, there is a sufficient degree of correlation between price trends for an
Underlying Fund's portfolio securities and futures contracts based on other
financial instruments, securities indices or other indices, an Underlying Fund
may also enter into such futures contracts as part of its hedging strategy.
Although under some circumstances prices of securities in an Underlying Fund's
portfolio may be more or less volatile than prices of  such futures contracts,
its investment adviser will attempt to estimate the extent of this volatility
difference based on historical patterns and compensate for any such differential
by having an Underlying Fund enter into a greater or lesser number of futures
contracts or by attempting to achieve only a partial hedge against price changes
affecting an Underlying Fund's portfolio securities.  When hedging of this
character is successful, any depreciation in the value of portfolio securities
will be substantially offset by appreciation in the value of the futures
position.  On the other hand, any unanticipated appreciation in the value of an
Underlying Fund's portfolio securities would be substantially offset by a
decline in the value of the futures position.

  On other occasions, an Underlying Fund may take a "long" position by
purchasing such futures contracts.  This would be done, for example, when an
Underlying Fund anticipates the subsequent purchase of particular securities
when it has the necessary cash, but expects the prices or currency exchange
rates then available in the applicable market to be less favorable than prices
or rates that are currently available.

  Options on Futures Contracts.  The acquisition of put and call options on
  ----------------------------                                             
futures contracts will give an Underlying Fund the right (but not the
obligation), for a specified price, to sell or to purchase, respectively, the
underlying futures contract at any time during the option period.  As the
purchaser of an option on a futures contract, an Underlying Fund obtains the
benefit of the futures position if prices move in a favorable direction but
limits its risk of loss in the event of an unfavorable price movement to the
loss of the premium and transaction costs.

  The writing of a call option on a futures contract generates a premium which
may partially offset a decline in the value of an Underlying Fund's assets.  By
writing a call option, an Underlying Fund becomes obligated, in exchange for the
premium, to sell a futures contract if the option is exercised, which may have a
value higher than the exercise price.  Conversely, the writing of a put option
on a futures contract generates a premium, which may partially offset an
increase in the price of securities that an Underlying Fund intends to purchase.
However, an Underlying Fund becomes obligated upon exercise of the option to
purchase a futures contract if the option is exercised, which may have a value
lower than the exercise price.  Thus, the loss incurred by an Underlying Fund in
writing 

                                     B-38
<PAGE>
 
options on futures is potentially unlimited and may exceed the amount of
the premium received.  An Underlying Fund will incur transaction costs in
connection with the writing of options on futures.

  The holder or writer of an option on a futures contract may terminate its
position by selling or purchasing an offsetting option on the same financial
instrument.  There is no guarantee that such closing transactions can be
effected.  An Underlying Fund's ability to establish and close out positions on
such options will be subject to the development and maintenance of a liquid
market.
    
  Other Considerations.  An Underlying Fund will engage in futures transactions
  --------------------                                                         
and related options transactions only for bona fide hedging as defined in the
regulations of the CFTC or to seek to increase total return to the extent
permitted by such regulations.     

  In addition to bona fide hedging, a CFTC regulation permits an Underlying Fund
to engage in other futures transactions if the aggregate initial margin and
premiums required to establish such positions in futures contracts and options
on futures do not exceed 5% of the net asset value of such Fund's portfolio,
after taking into account unrealized profits and losses on any such positions
and excluding the amount by which such options were in-the-money at the time of
purchase.  Transactions in futures contracts and related options may also be
limited by certain requirements that must be met in order for an Underlying Fund
to qualify as a regulated investment company for federal income tax purposes.
    
  Transactions in futures contracts and options on futures involve brokerage
costs, require margin deposits and, in certain cases, require the Underlying
Fund to segregate cash or liquid assets in an amount equal to the underlying
value of such contracts and options.     

  While transactions in futures contracts and options on futures may reduce
certain risks, such transactions themselves entail certain other risks.  Thus,
unanticipated changes in interest rates, securities prices or currency exchange
rates may result in a poorer overall performance for an Underlying Fund than if
it had not entered into any futures contracts or options transactions.  In the
event of an imperfect correlation between a futures position and a portfolio
position which is intended to be protected, the desired protection may not be
obtained and an Underlying Fund may be exposed to risk of loss.

  Perfect correlation between an Underlying Fund's futures positions and
portfolio positions will be difficult to achieve because no futures contracts
based on individual equity or corporate fixed-income securities are currently
available.  In addition, it is not possible for an Underlying Fund to hedge
fully or perfectly against currency fluctuations affecting the value of
securities quoted or denominated in foreign currencies because the value of such
securities is likely to fluctuate as a result of independent factors not related
to currency fluctuations.
    
  The profitability of a Fund's trading in futures to seek to increase total
return depends upon the ability of its investment adviser to analyze correctly
the futures markets.     

                                     B-39

Options on Securities and Securities Indices

  Writing Covered Options.  Certain of the Underlying Funds may write (sell)
  -----------------------                                                   
covered call and put options on any securities in which they may invest.  An
Underlying Fund may purchase and write such options on securities that are
listed on national domestic securities exchanges or foreign securities exchanges
or traded in the over-the-counter market.  A call option written by an
Underlying Fund obligates such Fund to sell specified securities to the holder
of the option at a specified price if the option is exercised at any time before
the expiration date.  All call options written by an Underlying Fund are
covered, which means that such Fund will own the securities subject to the
option as  long as the option is outstanding or such Fund will use the other
methods described below.  An Underlying Fund's purpose in writing covered call
options is to realize greater income than would be realized on portfolio
securities transactions alone.  However, an Underlying Fund may forego the
opportunity to profit from an increase in the market price of the underlying
security.
    
  A put option written by an Underlying Fund would obligate such Fund to
purchase specified securities from the option holder at a specified price if the
option is exercised at any time before the expiration date.  All put options
written by an Underlying Fund would be covered, which means that such Fund would
have segregated 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 Underlying Fund.  However, in return for the
option premium, each Fund accepts the risk that it may be required to purchase
the underlying securities at a price in excess of the securities' market value
at the time of purchase.     

  Call and put options written by an Underlying Fund will also be considered to
be covered to the extent that the Underlying Fund's liabilities under such
options are wholly or partially offset by its rights under call and put options
purchased by the Underlying Fund.
    
  In addition, a written call option or put option may be covered by segregating
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 an Underlying Fund's net exposure on its written option position.     

  The Underlying Funds 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.
    
  An Underlying Fund may cover call options on a securities index by owning
securities whose price changes are expected to be similar to those of the
underlying index, or by having an absolute and immediate right to acquire such
securities without additional cash consideration (or for additional cash
consideration which has been segregated by the Underlying Fund) upon conversion
or exchange of other securities in its portfolio.  An Underlying Fund may cover
call and put options on a securities index by segregating cash      

                                     B-40
<PAGE>
     
or liquid assets with a value equal to the exercise price or by using the other
methods described above.     

  An Underlying Fund may terminate its obligations under an exchange-traded call
or put option by purchasing an option identical to the one it has written.
Obligations under over-the-counter options may be terminated only by entering
into an offsetting transaction with the counterparty to such option.  Such
purchases are referred to as "closing purchase transactions."

  Purchasing Options.  Each Underlying Fund (other than CORE Large Cap Value,
  ------------------                                                         
CORE U.S. Equity, CORE Large Cap Growth and Financial Square Prime Obligations
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.  An Underlying Fund would also be able to enter into closing sale
transactions in order to realize gains or minimize losses on options it had
purchased.

  An Underlying Fund 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 an Underlying Fund, in return for
the premium paid, to purchase specified securities at a specified price during
the option period.  An Underlying Fund would ordinarily realize a gain if,
during the option period, the value of such securities exceeded the sum of the
exercise price, the premium paid and transaction costs; otherwise such an
Underlying Fund would realize either no gain or a loss on the purchase of the
call option.

  An Underlying Fund 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 an Underlying Fund, in exchange for the premium paid, to sell specified
securities at a specified price during the option period.  The purchase of
protective puts is designed to offset or hedge against a decline in the market
value of an Underlying Fund's securities.  Put options may also be purchased by
an Underlying Fund for the purpose of affirmatively benefiting from a decline in
the price of securities which it does not own.  An Underlying Fund would
ordinarily realize a gain if, during the option period, the value of the
underlying securities decreased below the exercise price sufficiently to more
than cover the premium and transaction costs; otherwise such an Underlying Fund
would realize either no gain or a loss on the purchase of the put option.  Gains
and losses on the purchase of protective put options would tend to be offset by
countervailing changes in the value of the underlying portfolio securities.

  An Underlying Fund would purchase put and call options on securities indices
for the same purposes as it would purchase options on individual securities.
For a description of options on securities indices, see "Writing Covered
Options" above.

  Yield Curve Options.  Each Underlying Fixed-Income Fund may enter into options
  -------------------                                                           
on the yield "spread" or differential between two securities.  Such transactions
are referred to as "yield curve" options.  In contrast to other types of
options, a yield curve option is based on the difference between the yields of
designated securities, rather than the prices of the individual securities, and
is settled through cash payments.  Accordingly, a yield curve option is
profitable to the holder if this differential widens (in the case of a call) or
narrows (in the case of a put), regardless of whether the yields of the
underlying securities increase or decrease.

                                     B-41
<PAGE>
 
  An Underlying Fund may purchase or write yield curve options for the same
purposes as other options on securities.  For example, an Underlying Fund may
purchase a call option on the yield spread between two securities if the
Underlying Fund owns one of the securities and anticipates purchasing the other
security and wants to hedge against an adverse change in the yield spread
between the two securities.  An Underlying Fund may also purchase or write yield
curve options in an effort to increase current income if, in the judgment of its
investment adviser, the Underlying Fund will be able to profit from movements in
the spread between the yields of the underlying securities.  The trading of
yield curve options is subject to all of the risks associated with the trading
of other types of options.  In addition, however, such options present risk of
loss even if the yield of one of the underlying securities remains constant, or
if the spread moves in a direction or to an extent which was not anticipated.
    
  Yield curve options written by an Underlying Fund will be "covered."  A call
(or put) option is covered if an Underlying Fund holds another call (or put)
option on the spread between the same two securities and segregates cash or
liquid assets sufficient to cover the Underlying Fund's net liability under the
two options.  Therefore, an Underlying Fund's liability for such a covered
option is generally limited to the difference between the amount of the
Underlying Fund's liability under the option written by the Underlying Fund less
the value of the option held by the Underlying Fund.  Yield curve options may
also be covered in such other manner as may be in accordance with the
requirements of the counterparty with which the option is traded and applicable
laws and regulations.  Yield curve options are traded over-the-counter, and the
trading markets for these options may not be as developed.     

  Risks Associated with Options Transactions.  There is no assurance that a
  ------------------------------------------                               
liquid secondary market on a domestic or foreign options exchange will exist for
any particular exchange-traded option or at any particular time.  If an
Underlying Fund is unable to effect a closing purchase  transaction with respect
to covered options it has written, the Underlying Fund will not be able to sell
the underlying securities or dispose of segregated assets until the options
expire or are exercised.  Similarly, if an Underlying Fund is unable to effect a
closing sale transaction with respect to options it has purchased, it will have
to exercise the options in order to realize any profit and will incur
transaction costs upon the purchase or sale of underlying securities.

  Reasons for the absence of a liquid secondary market on an exchange include
the following:  (i) there may be insufficient trading interest in certain
options; (ii) restrictions may be imposed by an exchange on opening or closing
transactions or both; (iii) trading halts, suspensions or other restrictions may
be imposed with respect to particular classes or series of options; (iv) unusual
or unforeseen circumstances may interrupt normal operations on an exchange; (v)
the facilities of an exchange or the Options Clearing Corporation may not at all
times be adequate to handle current trading volume; or (vi) one or more
exchanges could, for economic or other reasons, decide or be compelled at some
future date to discontinue the trading of options (or a particular class or
series of options), in which event the secondary market on that exchange (or in
that class or series of options) would cease to exist, although outstanding
options on that exchange that had been issued by the Options Clearing
Corporation as a result of trades on that exchange would continue to be
exercisable in accordance with their terms.

                                     B-42
<PAGE>
 
  An Underlying Fund may purchase and sell both options that are traded on U.S.
and foreign exchanges and options traded over-the-counter with broker-dealers
who make markets in these options.  The ability to terminate over-the-counter
options is more limited than with exchange-traded options and may involve the
risk that broker-dealers participating in such transactions will not fulfill
their obligations.
    
  Transactions by an Underlying Fund in options will be subject to limitations
established by each of the exchanges, boards of trade or other trading
facilities governing the maximum number of options in each class which may be
written or purchased by a single investor or group of investors acting in
concert.  Thus, the number of options which an Underlying Fund may write or
purchase may be affected by options written or purchased by other investment
advisory clients of the Underlying Funds' investment advisers.  An exchange,
board of trade or other trading facility may order the liquidation of positions
found to be in excess of these limits, and it may impose certain other
sanctions.     
    
  The writing and purchase of options is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions.  The use of options to seek to
increase total return involves the risk of loss if an investment adviser is
incorrect in its expectation of fluctuations in securities prices or interest
rates.  The successful use of options for hedging purposes also depends in part
on the ability of an investment adviser to predict future price fluctuations and
the degree of correlation between the options and securities markets.  If the an
investment adviser is incorrect in its expectation of changes in securities
prices or determination of the correlation between the securities indices on
which options are written and purchased and the securities in a Fund's
investment portfolio, the investment performance of the Fund will be less
favorable than it would have been in the absence of such options transactions.
The writing of options could increase a Fund's portfolio turnover rate and,
therefore, associated brokerage commissions or spreads.     

Warrants and Stock Purchase Rights

  Certain of the Underlying Funds may invest a portion of their assets in
warrants or rights (including those acquired in units or attached to other
securities) which entitle the holder to buy equity securities at a specific
price for a specific period of time.  An Underlying Fund will invest in warrants
and rights only if such securities are deemed appropriate by its investment
adviser for investment by the Underlying Fund.  Warrants and rights have no
voting rights, receive no dividends and have no rights with respect to the
assets of the issuer.

Foreign Investments
    
  Investments in foreign securities may offer potential benefits not available
from investments solely in U.S. dollar-denominated or quoted securities of
domestic issuers.  Such benefits may include the opportunity to invest in
foreign issuers that appear, in the opinion of an Underlying Fund's investment
adviser, to offer the potential for long-term growth of capital and income than
investments in U.S. securities, the opportunity to invest in foreign countries
with economic policies or business cycles different from those of the United
States and the opportunity to reduce fluctuations in portfolio value by taking
advantage of foreign securities markets that do not necessarily move in a manner
parallel to U.S. markets.     

                                     B-43
<PAGE>
     
  Investing in foreign securities also involves, however, certain special
considerations, including those set forth below, which are not typically
associated with investing in U.S. dollar-denominated or quoted securities of
U.S. issuers.  Investments in foreign securities usually involve currencies of
foreign countries. Accordingly, any Underlying Fund that invests in foreign
securities may be affected favorably or unfavorably by changes in currency rates
and in exchange control regulations and may incur costs in connection with
conversions between various currencies.  An Underlying Fund may be subject to
currency exposure independent of its securities positions.  To the extent that a
Fund is fully invested in foreign securities while also maintaining currency
positions, it may be exposed to greater combined risk.     
    
  Currency exchange rates may fluctuate significantly over short periods of
time.  They generally are determined by the forces of supply and demand in the
foreign exchange markets and the relative merits of investments in different
countries, actual or anticipated changes in interest rates and other complex
factors,  as seen from an international perspective.  Currency exchange rates
also can be affected unpredictably by intervention by U.S. or foreign
governments or central banks or the failure to intervene or by currency controls
or political developments in the United States or abroad.  To the extent that a
substantial portion of an Underlying Fund's total assets, adjusted to reflect
the Underlying Fund's net position after giving effect to currency transactions,
is denominated or quoted in the currencies of foreign countries, the Underlying
Fund will be more susceptible to the risk of adverse economic and political
developments within those countries.  In addition, if the currency in which an
Underlying Fund receives dividends, interest or other payment declines in value
against the U.S. dollar before such income is distributed as dividends to
shareholders or converted to U.S. dollars, the Underlying Fund may have to sell
portfolio securities to obtain sufficient cash to pay such dividends.     

  Since foreign issuers generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies, there may be less publicly
available information about a foreign company than about a U.S. company.  Volume
and liquidity in most foreign securities markets are less than in the United
States and securities of many foreign companies are less liquid and more
volatile than securities of comparable U.S. companies.  Fixed commissions on
foreign securities exchanges are generally higher than negotiated commissions on
U.S. exchanges, although each Underlying Fund endeavors to achieve the most
favorable net results on its portfolio transactions.  There is generally less
government supervision and regulation of foreign securities exchanges, brokers,
dealers and listed and unlisted companies than in the United States.

  Foreign markets also have different clearance and settlement procedures, and
in certain markets there have been times when settlements have been unable to
keep pace with the volume of securities transactions, making it difficult to
conduct such transactions.  Such delays in settlement could result in temporary
periods when some of an Underlying Fund's assets are uninvested and no return is
earned on such assets.  The inability of an Underlying Fund to make intended
security purchases due to settlement problems could cause the Underlying Fund to
miss attractive investment opportunities.  Inability to dispose of portfolio
securities due to settlement problems could result either in losses to an
Underlying Fund due to subsequent declines in value of the portfolio securities
or, if the Underlying Fund has entered into a contract to sell the securities,
could result in possible liability to the purchaser.  In addition, with respect
to certain foreign countries, there is the possibility of expropriation 

                                     B-44
<PAGE>
 
or confiscatory taxation, political or social instability, or diplomatic
developments which could affect an Underlying Fund's investments in those
countries. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, capital reinvestment, resource self-sufficiency and
balance of payments position.

  Investments in foreign securities may take the form of sponsored and
unsponsored American Depository Receipts ("ADRs"), Global Depository Receipts
("GDRs"), European Depository Receipts ("EDRs") or other similar instruments
representing securities of foreign issuers (together, "Depository Receipts").

  ADRs represent the right to receive securities of foreign issuers deposited in
a domestic bank or a correspondent bank.  ADRs are traded on domestic exchanges
or in the U.S. over-the-counter market and, generally, are in registered form.
EDRs and GDRs are receipts evidencing an arrangement with a non-U.S. bank
similar to that for ADRs and are designed for use in the non-U.S. securities
markets.  EDRs and GDRs are not necessarily quoted in the same currency as the
underlying security.

  To the extent an Underlying Fund acquires Depository Receipts through banks
which do not have a contractual relationship with the foreign issuer of the
security underlying the Depository Receipts to issue and service such Depository
Receipts (unsponsored), there may be an increased possibility that the
Underlying Fund would not become aware of and be able to respond to corporate
actions such as stock splits or rights offerings involving the foreign issuer in
a timely manner.  In addition, the lack of information may result in
inefficiencies in the valuation of such instruments.

  Certain of the Underlying Funds may invest in countries with emerging
economies or securities markets.  Political and economic structures in many of
such countries may be undergoing significant evolution and rapid development,
and such countries may lack the social, political and economic stability
characteristic of more developed countries.  Certain of such countries may have
in the past failed to recognize private property rights and have at times
nationalized or expropriated the assets of private companies.  As a result, the
risks described above, including the risks of nationalization or expropriation
of assets, may be heightened. See "Investing in Emerging Markets" below.
    
     
    
  Investing in Emerging Markets.  CORE International Equity, International
  -----------------------------                                           
Equity, European Equity, Japanese Equity, International Small Cap, Asia Growth
and Emerging Markets Equity Funds are intended for long-term investors who can
accept the risks associated with investing primarily in equity and equity-
related securities of foreign issuers, including (for certain Funds) emerging
country issuers, as well as the risks associated with investments quoted or
denominated in foreign currencies.  Growth and Income, Small Cap Value,
Mid Cap Value and Capital Growth Funds may invest, to a lesser extent, in equity
and equity-related securities of foreign issuers, including emerging country
issuers. The Core Fixed Income, Global Income and High Yield Funds may invest in
debt securities of foreign issuers, including emerging country issuers. In
addition, certain of the potential investment and management techniques of these
Funds entail special risks.    
                                     B-45
<PAGE>
     
  Each of the securities markets of the emerging countries is less liquid and
subject to greater price volatility and has a smaller market capitalization than
the U.S. securities markets.  Issuers and securities markets in such countries
are not subject to as extensive and frequent accounting, financial and other
reporting requirements or as comprehensive government regulations as are issuers
and securities markets in the U.S. In particular, the assets and profits
appearing on the financial statements of emerging country issuers may not
reflect their financial position or results of operations in the same manner as
financial statements for U.S. issuers.  Substantially less information may be
publicly available about emerging country issuers than is available about
issuers in the United States.     
    
  Emerging country securities markets are typically marked by a high
concentration of market capitalization and trading volume in a small number of
issuers representing a limited number of industries, as well as a high
concentration of ownership of such securities by a limited number of investors.
The markets for securities in certain emerging countries are in the earliest
stages of their development.  A Fund's investments in emerging countries are
subject to the risk that the liquidity of particular instruments, or instruments
generally in such countries, will shrink or disappear suddenly and without
warning as a result of adverse economic, market or political conditions, or
adverse investing perceptions, whether or not accurate.  Even the markets for
relatively widely traded securities in emerging countries may not be able to
absorb, without price disruptions, a significant increase in trading volume or
trades of a size customarily undertaken by institutional investors in the
securities markets of developed countries.  Additionally, market making and
arbitrage activities are generally less extensive in such markets, which may
contribute to increased volatility and reduced liquidity of such markets.  The
limited liquidity of emerging country securities may also affect an Underlying
Fund's ability to accurately value its portfolio securities or to acquire or
dispose of such securities at the price and times it wishes to do so.  The risks
associated with reduced liquidity may be particularly acute to the extent that
an Underlying Fund needs cash to meet redemption requests, to pay dividends and
other distributions or to pay its expenses.     
    
  Transaction costs, including brokerage commissions or dealer mark-ups, in
emerging countries may be higher than in the United States and other developed
securities markets.  In addition, existing laws and regulations are often
inconsistently applied.  As legal systems in emerging countries develop, foreign
investors may be adversely affected by new or amended laws and regulations.  In
circumstances where adequate laws exist, it may not be possible to obtain swift
and equitable enforcement of the law.     
    
  Foreign investment in the securities markets of certain emerging countries is
restricted or controlled to varying degrees.  These restrictions may limit an
Underlying Fund's investment in certain emerging countries and may increase the
expenses of the Underlying Fund.  Certain emerging countries require
governmental approval prior to investments by foreign persons or limit
investment by foreign persons to only a specified percentage of an issuer's
outstanding securities or a specific class of securities which may have less
advantageous terms (including price) than securities of the company available
for purchase by nationals.  In addition, the repatriation of both investment
income and capital from several of the emerging countries is subject to
restrictions which require governmental consents or prohibit repatriation
entirely for a period of time.  Even where there is no outright restriction on
repatriation of capital, the mechanics of repatriation may affect certain
aspects of the operation of an Underlying Fund.  An Underlying Fund may be     

                                     B-46
<PAGE>

     
required to establish special custodial or other arrangements before investing
in certain emerging countries.     
    
  Each of the emerging countries may be subject to a greater degree of economic,
political and social instability than is the case in the United States, Japan
and most Western European countries.  This instability may result from, among
other things, the following: (i) authoritarian governments or military
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 Underlying Funds may invest and
adversely affect the value of the Underlying 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.     

  An Underlying Fund's income and, in some cases, capital gains from foreign
stocks and securities will be subject to applicable taxation in certain of the
countries in which it invests, and treaties between the U.S. and such countries
may not be available in some cases to reduce the otherwise applicable tax rates.
    
  Foreign markets may also have different clearance and settlement procedures
and in certain U.S. markets, there have been times when settlements have been
unable to keep pace with the volume of securities transactions making it
difficult to conduct such transactions.  Delays in settlement could result in
temporary periods when a portion of an Underlying Fund's assets is uninvested
and no return is earned thereon.  The inability of an Underlying Fund to make
intended security purchases or sales due to settlement problems could result
either in losses to the Underlying Fund due to subsequent declines in value of
the portfolio securities or, if the Underlying Fund has entered into a contract
to sell the securities, could result in possible liability of the Underlying
Fund to the purchaser.  The creditworthiness of the local securities firms used
by a Fund in emerging countries may not be as sound as the creditworthiness of
firms used in more developed countries, thus subjecting the Fund to a greater
risk if a securities firm defaults in the performance of its 
responsibilities.     

  Investing in Japan.  The Japanese Equity Fund invests in the equity securities
  ------------------                                                            
of Japanese companies.  Japan's economy, the second-largest in the world, has
grown substantially over the last three 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 

                                     B-47
<PAGE>
 
sharply following the decline in asset prices. Profits have fallen sharply,
unemployment has reached a historical high and consumer confidence is low. The
banking sector continues to suffer from non-performing loans and this economy is
subject to deflationary pressures. Numerous discount-rate cuts since its peak in
1991, a succession of fiscal stimulus packages, support plans for the debt-
burdened financial system and spending for reconstruction following the Kobe
earthquake may help to contain the recessionary forces, but substantial
uncertainties remain.
    
  In addition to the cyclical downturn, Japan is suffering through structural
adjustments.  The Japanese have seen a deterioration of their competitiveness
due to high wages, a strong currency and structural rigidities.  Finally, Japan
is reforming its political process and deregulating its economy.  This has
brought about turmoil, uncertainty and a crisis of confidence.     

  While the Japanese governmental system itself seems stable, the dynamics of
the country's politics have been unpredictable in recent years.  The economic
crisis of 1990-92 brought the downfall of the conservative Liberal Democratic
Party, which had ruled since 1955.  Since then, the country has seen a series of
unstable multi-party coalitions and several prime ministers come and go, because
of politics as well as personal scandals.  While there appears to be no reason
for anticipating civic unrest, it is impossible to know when the political
instability will end and what trade and fiscal policies might be pursued by the
government that emerges.

  Japan's heavy dependence on international trade has been adversely affected by
trade tariffs and other protectionist measures as well as the economic condition
of its trading partners.  While Japan subsidizes its agricultural industry, only
19% of its land is suitable for cultivation and it is only 50% self-sufficient
in food production.  Accordingly, it is highly dependent on large imports of
wheat, sorghum and soybeans.  In addition, industry, its most important economic
sector, depends on imported raw materials and fuels, including iron ore, copper,
oil and many forest products.  Japan's high volume of exports, such as
automobiles, machine tools and semiconductors, have caused trade tensions,
particularly with the United States.  Some trade agreements, however, have been
implemented to reduce these tensions.  The relaxing of official and de facto
barriers to imports, or hardships created by any pressures brought by trading
partners, could adversely affect Japan's economy.  A substantial rise in world
oil or commodity prices could also have a negative affect.  The strength of the
yen itself may prove an impediment to strong continued exports and economic
recovery, because it makes Japanese goods sold in other countries more expensive
and reduces the value of foreign earnings repatriated to Japan.  Because the
Japanese economy is so dependent on exports, any fall-off in exports may be seen
as a sign of economic weakness, which may adversely affect the market.

  Geologically, Japan is located in a volatile area of the world, and has
historically been vulnerable to earthquakes, volcanoes and other natural
disasters.  As demonstrated by the Kobe earthquake in January of 1995, in which
5,000 people were killed and billions of dollars of damage was sustained, these
natural disasters can be significant enough to affect the country's economy.
    
  Sovereign Debt Obligations.  Investments in sovereign debt obligations involve
special risks not present in corporate debt obligations.  The issuer of the
sovereign debt or the governmental authorities that control the repayment of the
debt may be unable or unwilling to      

                                     B-48
<PAGE>
 
repay principal or interest when due, and an Underlying Fund may have limited
recourse in the event of a default. During periods of economic uncertainty, the
market prices of sovereign debt, and an Underlying Fund's net asset value, may
be more volatile than prices of debt obligations of U.S. issuers. In the past,
the governments of certain emerging markets have encountered difficulties in
servicing their debt obligations, withheld payments of principal and interest
and declared moratoria on the payment of principal and interest on their
sovereign debts.

  A sovereign debtor's willingness or ability to repay principal and pay
interest in a timely manner may be affected by, among other factors, its cash
flow situation, the extent of its foreign currency reserves, the availability of
sufficient foreign exchange, the relative size of the debt service burden, the
sovereign debtor's policy toward principal international lenders and local
political constraints.  Sovereign debtors may also be dependent on expected
disbursements from foreign governments, multinational agencies and other
entities to reduce principal and interest arrearages on their debt.  The failure
of a sovereign debtor to implement economic reforms, achieve specified levels of
economic performance or repay principal or interest when due may result in the
cancellation of the third parties' commitments to lend funds to the sovereign
debtor, which may further impair such debtor's ability or willingness to timely
service its debts.

  Forward Foreign Currency Exchange Contracts.  Certain of the Underlying Funds
may enter into forward foreign currency exchange contracts for hedging purposes.
CORE International Equity, International Equity, European Equity, Japanese
Equity, International Small Cap, Emerging Markets Equity, Asia Growth, Global
Income, Core Fixed Income and High Yield Funds may also enter into forward
foreign currency exchange contracts to seek to increase total return.  A forward
foreign currency exchange contract involves an obligation to purchase or sell a
specific currency at a future date, which may be any fixed number of days from
the date of the contract agreed upon by the parties, at a price set at the time
of the contract.  These contracts are traded in the interbank market between
currency  traders (usually large commercial banks) and their customers.  A
forward contract generally has no deposit requirement, and no commissions are
generally charged at any stage for trades.

  At the maturity of a forward contract an Underlying Fund may either accept or
make delivery of the currency specified in the contract or, at or prior to
maturity, enter into a closing transaction involving the purchase or sale of an
offsetting contract. Closing  transactions with respect to forward contracts are
often, but not always, effected with the currency trader who is a party to the
original forward contract.

  An Underlying Fund may enter into forward foreign currency exchange contracts
in several circumstances.  First, when an Underlying Fund enters into a contract
for the purchase or sale of a security denominated or quoted in a foreign
currency, or when an Underlying Fund anticipates the receipt in a foreign
currency of dividend or interest payments on such a security which it holds, the
Underlying Fund may desire to "lock in" the U.S. dollar price of the security or
the U.S. dollar equivalent of such dividend or interest payment, as the case may
be.  By entering into a forward contract for the purchase or sale, for a fixed
amount of dollars, of the amount of foreign currency involved in the underlying
transactions, the Underlying Fund will attempt to protect itself against an
adverse change in the relationship between the U.S. dollar and the subject
foreign currency during the period between the date on which the security is
purchased or sold, or on which the dividend or interest payment is declared, and
the date on which such payments are made or received.


                                     B-49
<PAGE>
 
  Additionally, when an Underlying Fund's investment adviser believes that the
currency of a particular foreign country may suffer a substantial decline
against the U.S. dollar, it may enter into a forward contract to sell, for a
fixed amount of U.S. dollars, the amount of foreign currency approximating the
value of some or all of an Underlying Fund's portfolio securities quoted or
denominated in such foreign currency.  The precise matching of the forward
contract amounts and the value of the securities involved will not generally be
possible because the future value of such securities in foreign currencies will
change as a consequence of market movements in the value of those securities
between the date on which the contract is entered into and the date it matures.
Using forward contracts to protect the value of an Underlying Fund's portfolio
securities against a decline in the value of a currency does not eliminate
fluctuations in the underlying prices of the securities.  It simply establishes
a rate of exchange which an Underlying Fund can achieve at some future point in
time.  The precise projection of short-term currency market movements is not
possible, and short-term hedging provides a means of fixing the U.S. dollar
value of only a portion of an Underlying Fund's foreign assets.

  The CORE International Equity, International Equity, European Equity, Japanese
Equity, International Small Cap, Emerging Markets Equity, Asia Growth, Core
Fixed Income, Global Income and High Yield Funds may engage in cross-hedging by
using forward contracts in one currency to hedge against fluctuations in the
value of securities quoted or denominated in a different currency if an
Underlying Fund's investment adviser determines that there is a pattern of
correlation between the two currencies.  These Funds may also purchase and sell
forward contracts to seek to increase total return when an Underlying Fund's
investment adviser anticipates that the foreign currency will appreciate or
depreciate in value, but securities quoted or denominated in that currency do
not present attractive investment opportunities and are not held in the
Underlying Fund's portfolio.
    
  Unless otherwise covered, cash or liquid assets of an Underlying Fund will be
segregated in an amount equal to the value of the Underlying Fund's total assets
committed to the consummation of forward foreign currency exchange contracts
requiring the Fund to purchase foreign currencies and forward contracts entered
into to seek to increase total return.  The segregated assets will be marked-to-
market on a daily basis.  If the value of the segregated assets declines,
additional liquid assets will be segregated so that the value will equal the
amount of an Underlying Fund's commitments with respect to such contracts.
Although the contracts are not presently regulated by the CFTC, the CFTC may in
the future assert authority to regulate these contracts.  In such event, an
Underlying Fund's ability to utilize forward foreign currency exchange contracts
may be restricted.  The Core Fixed-Income, Global Income and High Yield Funds
will not enter into a forward contract with a term of greater than one 
year.     
    
  While an Underlying Fund may enter into forward contracts to reduce currency
exchange rate risks, transactions in such contracts involve certain other risks.
Thus, while an Underlying Fund may benefit from such transactions, unanticipated
changes in currency prices may result in a poorer overall performance for the
Underlying Fund than if it had not engaged in any such transactions.  Moreover,
there may be imperfect correlation between an Underlying Fund's portfolio
holdings of securities quoted or denominated in a particular currency and
forward contracts entered into by such Fund.  Such imperfect correlation may
cause an Underlying Fund to sustain losses which will prevent the Underlying
Fund from achieving a complete hedge or expose the Underlying Fund to risk of
foreign exchange loss.

  Markets for trading foreign forward currency contracts offer less protection
against defaults than is available when trading in currency instruments on an
exchange.  Forward contracts are subject to the risk that the counterparty to
such contract will default on its obligations.  Since a forward foreign currency
exchange contract is not guaranteed by an exchange or clearinghouse, a default
on the contract would deprive an Underlying Fund of unrealized profits,
transaction costs or the benefits of a currency hedge or force the Underlying
Fund to cover its purchase or sale commitments, if any, at the current market
price.     

  Forward contracts are subject to the risk that the counterparty to such

transaction costs or the benefits of a currency hedge or force the Underlying
Fund to cover its purchase or sale commitments, if any, at the current market
price.  An Underlying Fund will not enter into such transactions unless the
credit quality of the unsecured senior debt or the claims-paying ability of the
counterparty is considered to be investment grade by its investment adviser.
    
  Writing and Purchasing Currency Call and Put Options. Certain of the
Underlying Funds may 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 foreign portfolio securities and against
increases in the U.S. dollar cost of foreign securities to be acquired.  As with
other kinds of option transactions, however, the writing of an option on foreign
currency will constitute only a partial hedge, up to the amount of the premium
received.  If and when an Underlying Fund seeks to close out an option, the
Underlying Fund could be required to purchase or sell foreign currencies at
disadvantageous exchange rates, thereby incurring losses.  The purchase of an
option on foreign currency may constitute an effective hedge against exchange
rate fluctuations; however, in the event of exchange rate movements adverse to
an Underlying Fund's position, the Underlying Fund may forfeit the entire amount
of the premium plus related transaction costs.  Options on foreign currencies
written or purchased by an Underlying Fund will be traded on U.S. and foreign
exchanges or over-the-counter.     

  CORE International Equity, International Equity, European Equity, Japanese
Equity, International Small Cap, Emerging Markets Equity, Asia Growth, Core
Fixed Income, Global Income and High Yield 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, certain Underlying Funds may purchase call or put
options on currency to seek to increase total return when an Underlying Fund's
investment adviser anticipates that the currency will appreciate or depreciate
in value, but the securities quoted or denominated in that currency do not
present attractive investment opportunities and are not included in the
Underlying Fund's portfolio.

  A call option written by an Underlying Fund obligates an Underlying Fund to
sell specified currency to the holder of the option at a specified price if the
option is exercised before the expiration date.  A put option written by an
Underlying Fund would obligate an Underlying Fund to purchase specified currency
from the option holder at a specified price if the option is exercised at any
time before the expiration date.  The writing of currency options involves a
risk that an Underlying Fund  will, upon exercise of the option, be required 

                                     B-51
<PAGE>
 
to sell currency subject to a call at a price that is less than the currency's
market value or be required to purchase currency subject to a put at a price
that exceeds the currency's market value. For a description of how to cover
written put and call options, see "Writing Covered Options" above.
    
  An Underlying Fund may terminate its obligations under a call or put option by
purchasing an option identical to the one it has written.  Such purchases are
referred to as "closing purchase transactions."  An Underlying Fund may enter
into closing sale transactions in order to realize gains or minimize losses on
options purchased by the Underlying Fund.     

  An Underlying Fund would normally purchase call options on foreign currency in
anticipation of an increase in the U.S. dollar value of currency in which
securities to be acquired by an Underlying Fund are quoted or denominated.  The
purchase of a call option would entitle the Underlying Fund, in return for the
premium paid, to purchase specified currency at a specified price during the
option period.  An Underlying Fund would ordinarily realize a gain if, during
the option period, the value of such currency exceeded the sum of the exercise
price, the premium paid and transaction costs; otherwise the Underlying Fund
would realize either no gain or a loss on the purchase of the call option.

  An Underlying Fund would normally purchase put options in anticipation of a
decline in the U.S. dollar value of currency in which securities in its
portfolio are quoted or denominated ("protective puts"). The purchase of a put
option would entitle an Underlying Fund, in exchange for the premium paid, to
sell specified currency at a specified price during the option period.  The
purchase of protective puts is designed merely to offset or hedge against a
decline in the dollar value of an Underlying Fund's portfolio securities due to
currency exchange rate fluctuations.  An Underlying Fund would ordinarily
realize a gain if, during the option period, the value of the underlying
currency decreased below the exercise price sufficiently to more than cover the
premium and transaction costs; otherwise the Underlying Fund would realize
either no gain or a loss on the purchase of the put option.  Gains and losses on
the purchase of protective put options would tend to be offset by countervailing
changes in the value of underlying currency or portfolio securities.

  In addition to using options for the hedging purposes described above, certain
Underlying Funds may use options on currency to seek to increase total return.
These Funds may write (sell) covered put and call options on any currency in
order to realize greater income than would be realized on portfolio securities
transactions alone.  However, in writing covered call options for additional
income, an Underlying Fund may forego the opportunity to profit from an increase
in the market value of the  underlying currency.  Also, when writing put
options, an Underlying Fund accepts, in return for the option premium, the risk
that it may be required to purchase the underlying currency at a price in excess
of the currency's market value at the time of purchase.
    
  Special Risks Associated With Options on Currency. An exchange traded option
position may be closed out only on an options exchange which provides a
secondary market for an option of the same series.  There is no assurance that a
liquid secondary market on an exchange will exist for any particular option, or
at any particular time.  In such event, it might not be possible to effect
closing transactions in particular options, with the result that an Underlying
Fund would have to exercise its options in order to realize any profit and would
incur transaction costs upon the sale of underlying securities pursuant to the
exercise of put      

                                     B-52
<PAGE>

     
options. If an Underlying Fund as a covered call option writer is unable to
effect a closing purchase transaction in a secondary market, it may not be able
to sell the underlying currency (or security quoted or denominated in that
currency) until the option expires or it delivers the underlying currency upon
exercise.     

  There is no assurance that higher than anticipated trading activity or other
unforeseen events might not, at times, render certain of the facilities of the
Options Clearing Corporation inadequate, and thereby result in the institution
by an exchange of special procedures which may interfere with the timely
execution of customers' orders.

  An Underlying Fund may purchase and write over-the-counter options to the
extent consistent with its limitation on investments in illiquid securities.
Trading in over-the-counter options is subject to the risk that the other party
will be unable or unwilling to close out options purchased or written by an
Underlying Fund.

  The amount of the premiums which an Underlying Fund may pay or receive may be
adversely affected as new or existing institutions, including other investment
companies, engage in or increase their option purchasing and writing activities.

Mortgage Dollar Rolls
    
  Certain of the Underlying Fixed-Income Funds may enter into mortgage "dollar
rolls" in which an Underlying Fund sells securities for delivery in the current
month and simultaneously contracts with the same counterparty to repurchase
similar (same type, coupon and maturity), but not identical securities on a
specified future date.  During the roll period, an Underlying Fund loses the
right to receive principal and interest paid on the securities sold.  However,
an Underlying Fund would benefit to the extent of any difference between the
price received for the securities sold and the lower forward price for the
future purchase (often referred to as the "drop") or fee income plus the
interest earned on the cash proceeds of the securities sold until the settlement
date of the forward purchase.  Unless such benefits exceed the income, capital
appreciation and gain or loss due to mortgage prepayments that would have been
realized on the securities sold as part of the mortgage dollar roll, the use of
this technique will diminish the investment performance of an Underlying Fund
compared with what such performance would have been without the use of mortgage
dollar rolls.  All cash proceeds will be invested in instruments that are
permissible investments for the applicable Fund.  An Underlying Fund segregate
until the settlement date cash or liquid assets, as permitted by applicable law,
in an amount equal to its forward purchase price.     

  For financial reporting and tax purposes, the Underlying Funds treat mortgage
dollar rolls as two separate transactions; one involving the purchase of a
security and a separate transaction involving a sale.  The Underlying Funds do
not currently intend to enter into mortgage dollar rolls that are accounted for
as a financing.

  Mortgage dollar rolls involve certain risks including the following:  if the
broker-dealer to whom an Underlying Fund sells the security becomes insolvent,
an Underlying Fund's right to purchase or repurchase the mortgage-related
securities subject to the mortgage dollar roll may be restricted and the
instrument which an Underlying Fund is required to repurchase may be worth less
than an instrument which an Underlying Fund originally held.  Successful use of
mortgage dollar rolls will depend upon the ability of an 

                                     B-53
<PAGE>
 
Underlying Fund's investment adviser to manage an Underlying Fund's interest
rate and mortgage prepayments exposure. For these reasons, there is no assurance
that mortgage dollar rolls can be successfully employed.

Convertible Securities
    
  Convertible securities include corporate notes or preferred stock but are
ordinarily long-term debt obligations of the issuer convertible at a stated
exchange rate into common stock of the issuer.  As with all debt securities, the
market value of convertible securities tends to decline as interest rates
increase and, conversely, to increase as interest rates decline.  Convertible
securities generally offer lower interest or dividend yields than non-
convertible securities  of similar quality.  However, when the market price of
the common stock underlying a convertible security exceeds the conversion price,
the price of the convertible security tends to reflect the value of the
underlying common stock.  As the market price of the underlying common stock
declines, the convertible security tends to trade increasingly on a yield basis,
and thus may not depreciate to the same extent as the underlying common stock.
Convertible securities rank senior to common stocks in an issuer's capital
structure and consequently entail less risk than the issuer's common stock.     

Currency Swaps, Mortgage Swaps, Credit Swaps, Index Swaps and Interest Rate
Swaps, Caps, Floors and Collars
    
  The CORE International Equity, International Equity, Emerging Markets Equity,
European Equity, Japanese Equity, Asia Growth, International Small Cap, Core
Fixed Income, Global Income and High Yield Funds may enter into currency swaps
for both hedging purposes and to seek to increase total return.  In addition,
the Underlying Fixed-Income Funds and Real Estate Securities Fund may enter into
mortgage, credit, index and interest rate swaps and other interest rate swap
arrangements such as rate caps, floors and collars, for hedging purposes or to
seek to increase total return.  Currency swaps involve the exchange by an
Underlying Fund with another party of their respective rights to make or receive
payments in specified currencies.  Interest rate swaps involve the exchange by
an Underlying Fund with another party of their respective commitments to pay or
receive interest, such as an exchange of fixed rate payments for floating rate
payments.  Mortgage swaps are similar to interest rate swaps in that they
represent commitments to pay and receive interest.  The notional principal
amount, however, is tied to a reference pool or pools of mortgages.  Index swaps
involve the exchange by an Underlying Fund with another party of the respective
amounts payable with respect to a notional principal amount at interest rates
equal to two specified indices.  The purchase of an interest rate cap entitles
the purchaser, to the extent that a specified index exceeds a predetermined
interest rate, to receive payment of interest on a notional principal amount
from the party selling such interest rate cap.  Credit swaps involve the receipt
of floating or fixed rate payments in exchange for assuming potential credit
losses of an underlying security.  Credit swaps give one party to a transaction
the right to dispose of or acquire an asset (or group of assets), or the right
to receive or make a payment from the other party, upon the occurrence of
specified credit events.  The purchase of an interest rate floor entitles the
purchaser, to the extent that a specified index falls below a predetermined
interest rate, to receive payments of interest on a notional principal amount
from the party selling the interest rate floor.  An interest rate collar is the
combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates.  Since interest rate, mortgage and
currency swaps and interest rate caps, floors and collars are individually
negotiated, each Fund expects to achieve an      

                                     B-54
<PAGE>
 
acceptable degree of correlation between its portfolio investments and its swap,
cap, floor and collar positions.

    
  An Underlying Fund will enter into interest rate, mortgage and index swaps
only on a net basis, which means that the two payment streams are netted out,
with the Underlying Fund receiving or paying, as the case may be, only the net
amount of the two payments.  Interest rate, index and mortgage swaps do not
involve the delivery of securities, other underlying assets or principal.
Accordingly, the risk of loss with respect to interest rate, index and mortgage
swaps is limited to the net amount of interest payments that the Underlying Fund
is contractually obligated to make.  If the other party to an interest rate,
index or mortgage swap defaults, the Underlying Fund's risk of loss consists of
the net amount of interest payments that the Underlying Fund is contractually
entitled to receive, if any.  In contrast, currency swaps usually involve the
delivery of the entire principal amount of one designated currency in exchange
for the other designated currency.  Therefore, the entire principal value of a
currency swap is subject to the risk that the other party to the swap will
default on its contractual delivery obligations.  To the extent that the net
amount payable under an interest rate, index or mortgage swap and the entire
amount of the payment stream payable by an Underlying Fund under a currency swap
or an interest rate floor, cap or collar are covered by segregated cash or
liquid assets, the Underlying Funds and their investment advisers believe that
transactions do not constitute senior securities under the Act and, accordingly,
will not treat them as being subject to an Underlying Fund's borrowing
restrictions.     

  An Underlying Equity Fund will not enter into swap transactions unless the
unsecured commercial paper, senior debt or claims paying ability of the other
party thereto is considered to be investment grade by its investment adviser.
The Underlying Fixed-Income Funds will not enter into any interest rate,
mortgage or credit swap transactions unless the unsecured commercial paper,
senior debt or claims-paying ability of the other party is rated either AA or A-
1 or better by Standard & Poor's or Aa or P-1 or better by Moody's or, if
unrated by such rating agencies, determined to be of comparable quality by the
applicable investment adviser.  The Core Fixed Income, Global Income and High
Yield Funds will not enter into any currency swap transactions unless the
unsecured commercial paper, senior debt or claims-paying ability of the other
party thereto is rated investment grade by Standard & Poor's or Moody's or their
equivalent ratings or, if unrated by such rating agencies, determined to be of
comparable quality by the applicable investment adviser.  If there is a default
by the other party to such a transaction, an Underlying Fund will have
contractual remedies pursuant to  the agreements related to the transaction.
The swap market has grown substantially in recent years with a large number of
banks and investment banking firms acting both as principals and as agents
utilizing standardized swap documentation.  As a result, the swap market has
become relatively liquid in comparison with the markets for other similar
instruments which are traded in the interbank market.   The investment advisers,
under the supervision of the Board of Trustees, are responsible for determining
and monitoring the liquidity of the Underlying Funds' transactions in swaps,
caps, floors and collars.

  The use of interest rate, mortgage, credit, index and currency swaps, as well
as interest rate caps, floors and collars, is a highly specialized activity
which involves investment techniques and risks different from those associated
with ordinary portfolio securities transactions.  If an Underlying Fund's
investment adviser is incorrect in its forecasts of market values, interest
rates and currency exchange rates, the investment 

                                     B-55
<PAGE>
 
performance of an Underlying Fund would be less favorable than it would have
been if this investment technique were not used.

Equity Swaps

  Each Underlying Equity Fund may enter into equity swap contracts to invest in
a market without owning or taking physical custody of securities in
circumstances in which direct investment is restricted for legal reasons or is
otherwise impracticable.  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 Underlying Fund the amount, if any, by which the
notional amount of the equity swap contract would have increased in value had it
been invested in the particular stocks, plus the dividends that would have been
received on those stocks.  The Underlying 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 Underlying 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
Underlying Fund on the notional amount.
    
  An Underlying Fund will enter into equity swaps only on a net basis, which
means that the two payment streams are netted out, with the Underlying Fund
receiving or paying, as the case may be, only the net amount of the two
payments.  Payments may be made at the conclusion of an equity swap contract or
periodically during its term.  Equity swaps do not involve the delivery of
securities or other underlying assets.  Accordingly, the risk of loss with
respect to equity swaps is limited to the net amount of payments that an
Underlying Fund is contractually obligated to make.  If the other party to an
equity swap defaults, an Underlying Fund's risk of loss consists of the net
amount of payments that such Fund is contractually entitled to receive, if any.
The net amount of the excess, if any, of an Underlying 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 segregated.  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 Underlying
Funds and their investment advisers believe that transactions do not constitute
senior securities under the Act and, accordingly, will not treat them as being
subject to an Underlying Fund's borrowing restrictions.     

    
     

Real Estate Investment Trusts

  The Underlying Equity Funds may invest in shares of REITs.  REITs are pooled
investment vehicles which invest primarily in income producing real estate or
real estate related loans or interest.  REITs are generally classified as equity
REITs, mortgage REITs or a combination of equity and mortgage REITs.  Equity
REITs invest the majority of their assets directly in real property and derive
income primarily from the collection of rents.  Equity REITs can also realize
capital gains by selling properties that have appreciated in value.  Mortgage
REITs invest the majority of their assets in real estate mortgages and derive
income from the collection of interest payments. Like regulated investment
companies such as the Underlying Funds, REITs are not taxed on income
distributed to shareholders provided they comply with certain requirements under
the Code.  An Underlying Fund will indirectly 

                                     B-56
<PAGE>
 
bear its proportionate share of any expenses paid by REITs in which it invests
in addition to the expenses paid by an Underlying Fund.

  Investing in REITs involves certain unique risks.  Equity REITs may be
affected by changes in the value of the underlying property owned by such REITs,
while mortgage REITs may be affected by the quality of any credit extended.
REITs are dependent upon management skills, are not diversified (except to the
extent the Code requires), and are subject to the risks of financing projects.
REITs are subject to heavy cash flow dependency, default by borrowers, self-
liquidation, and the possibilities of failing to qualify for the exemption from
tax for distributed  income under the Code and failing to maintain their
exemptions from the Act.  REITs (especially mortgage REITs) are also subject to
interest rate risks.

Lending of Portfolio Securities

  The Underlying Funds may lend portfolio securities.  Under present regulatory
policies, such loans may be made to institutions such as brokers or dealers and
would be required to be secured continuously by collateral in cash, cash
equivalents or U.S.  Government securities maintained on a current basis at an
amount at least equal to the market value of the securities loaned.  An
Underlying Fund would be required to have the right to call a loan and obtain
the securities loaned at any time on five days' notice.  For the duration of a
loan, an Underlying Fund would continue to receive the equivalent of the
interest or dividends paid by the issuer on the securities loaned and would also
receive compensation from investment of the collateral.  An Underlying Fund
would not have the right to vote any securities having voting rights during the
existence of the loan, but an Underlying Fund would call the loan in
anticipation of an important vote to be taken among holders of the securities or
the giving or withholding of their consent on a material matter affecting the
investment.  As with other extensions of credit there are risks of delay in
recovering, or even loss of rights in, the collateral should the borrower of the
securities fail financially.  However, the loans would be made only to firms
deemed by an Underlying Fund's investment adviser to be of good standing, and
when, in the judgment of an Underlying Fund's investment adviser, the
consideration which can be earned currently from securities loans of this type
justifies the attendant risk.  If an investment adviser determines to make
securities loans, it is intended that the value of the securities loaned would
not exceed one-third of the value of the total assets of an Underlying Fund
(including the loan collateral).

When-Issued Securities and Forward Commitments

  Each Underlying Fund may purchase securities on a when-issued basis or
purchase or sell securities on a forward commitment basis.  These transactions
involve a commitment by an Underlying Fund to purchase or sell securities at a
future date.  The price of the underlying securities (usually expressed in terms
of yield) and the date when the securities will be delivered and paid for (the
settlement date) are fixed at the time the transaction is negotiated.  When-
issued purchases and forward commitment transactions are negotiated directly
with the other party, and such commitments are not traded on exchanges.  An
Underlying Fund will purchase securities on a when-issued basis or purchase or
sell securities on a forward commitment basis only with the intention of
completing the transaction and actually purchasing or selling the securities.
If deemed advisable as a matter of investment strategy, however, an Underlying
Fund may dispose of or negotiate a commitment after entering into it.   The
Underlying Funds may also realize a capital gain or loss in connection with
these 

                                     B-57
<PAGE>
 
transactions. For purposes of determining an Underlying Fund's duration, the
maturity of when-issued or forward commitment securities will be calculated from
the commitment date. An Underlying Fund is required to segregate until three
days prior to the settlement date, cash and liquid assets in an amount
sufficient to meet the purchase price. Alternatively, an Underlying Fund may
enter into offsetting contracts for the forward sale of other securities that it
owns. Securities purchased or sold on a when-issued or forward commitment basis
involve a risk of loss if the value of the security to be purchased declines
prior to the settlement date or if the value of the security to be sold
increases prior to the settlement date.

Investment in Unseasoned Companies
    
  The Underlying Funds may invest a portion of their net assets in companies
(including predecessors) which have operated less than three years, except that
this limitation does not apply to debt securities which have been rated
investment grade or better by at least one NRSRO.  The securities of such
companies may have limited liquidity, which can result in their being priced
higher or lower than might otherwise be the case.  In addition, investments in
unseasoned companies are more speculative and entail greater risk than do
investments in companies with an established operating record.     

Other Investment Companies

  Each of the Underlying Funds may make limited investments in the securities of
other investment companies including, pursuant to an exemptive order obtained
from the SEC, money market funds for which the Adviser or any of its affiliates
serves as investment adviser.  An Underlying Fund will indirectly bear its
proportionate share of any management fees and other expenses paid by investment
companies in which it invests in addition to the advisory and administration
fees paid by the Underlying Fund.  However, to the extent that the Underlying
Fund invests in a money market fund for which the Adviser or any of its
affiliates acts as adviser, the advisory and administration fees payable by the
Underlying Fund to the investment adviser or its affiliates will be reduced by
an amount equal to the Underlying Fund's proportionate share of the advisory and
administration fees paid by such money market fund to the investment adviser or
its affiliates.

  Each Underlying Equity Fund may also invest in SPDRs.  SPDRs are interests in
a unit investment trust ("UIT") that may be obtained from the UIT or purchased
in the secondary market (SPDRs are listed on the American Stock Exchange).  The
UIT will issue SPDRs in aggregations known as "Creation Units" in exchange for a
"Portfolio Deposit" consisting of (a) a portfolio of securities substantially
similar to the component securities ("Index Securities") of the Standard &
Poor's 500 Composite Stock Price Index (the "S&P Index"), (b) a cash payment
equal to a pro rata portion of the dividends accrued on the UIT's portfolio
securities since the last dividend payment by the UIT, net of expenses and
liabilities, and (c) a cash payment or credit ("Balancing Amount") designed to
equalize the net asset value of the S&P Index and the net asset value of a
Portfolio Deposit.
    
  SPDRs are not individually redeemable, except upon termination of the UIT.  To
redeem, the Underlying Fund must accumulate enough SPDRs to reconstitute a
Creation Unit.  The liquidity of small holdings of SPDRs, therefore, will depend
upon the existence of a secondary market.  Upon redemption of a Creation Unit,
the Underlying Fund will receive Index Securities and cash identical to the
Portfolio Deposit required of an investor wishing to purchase a Creation Unit
that day.     

                                     B-58
<PAGE>
 
  The price of SPDRs is derived from and based upon the securities held by the
UIT.  Accordingly, the level of risk involved in the purchase or sale of a SPDR
is similar to the risk involved in the purchase or sale of traditional common
stock, with the exception that the pricing mechanism for SPDRs is based on a
basket of stocks.  Disruptions in the markets for the securities underlying
SPDRs purchased or sold by the Underlying Funds could result in losses on SPDRs.

  Certain Underlying Funds may also purchase shares of investment companies
investing primarily in foreign securities, including "country funds."  Country
funds have portfolios consisting primarily of securities of issuers located in
one foreign country or region.  Certain Underlying Funds may also invest in
World Equity Benchmark Shares ("WEBS") and similar securities that invest in
securities included in foreign securities indices.

Repurchase Agreements
    
  Each Underlying Fund may enter into repurchase agreements with selected
broker-dealers, banks and other financial institutions.  A repurchase agreement
is an arrangement under which an Underlying Fund purchases securities and the
seller agrees to repurchase the securities within a particular time and at a
specified price.  Custody of the securities is maintained by an Underlying
Fund's custodian.  The repurchase price may be higher than the purchase price,
the difference being income to an Underlying Fund, or the purchase and
repurchase prices may be the same, with interest at a stated rate due to an
Underlying Fund together with the repurchase price on repurchase.  In either
case, the income to an Underlying Fund is unrelated to the interest rate on the
security subject to the repurchase agreement.     

  For purposes of the Act and generally for tax purposes, a repurchase agreement
is deemed to be a loan from an Underlying Fund to the seller of the security.
For other purposes, it is not always clear whether a court would consider the
security purchased by an Underlying Fund subject to a repurchase agreement as
being owned by an Underlying Fund or as being collateral for a loan by an
Underlying Fund to the seller.  In the event of commencement of bankruptcy or
insolvency proceedings with respect to the seller of the security before
repurchase of the security under a repurchase agreement, an Underlying Fund may
encounter delay and incur costs before being able to sell the security.  Such a
delay may involve loss of interest or a decline in price of the security.  If
the court characterizes the transaction as a loan  and an Underlying Fund has
not perfected a security interest in the security, an Underlying Fund may be
required to return the security to the seller's estate and be treated as an
unsecured creditor of the seller.  As an unsecured creditor, an Underlying Fund
would be at risk of losing some or all of the principal and interest involved in
the transaction.
    
  The Underlying Fund's investment adviser seeks to minimize the risk of loss
from repurchase agreements by analyzing the creditworthiness of the obligor, in
this case the seller of the security.  Apart from the risk of bankruptcy or
insolvency proceedings, there is also the risk that the seller may fail to
repurchase the security.  However, if the market value of the security subject
to the repurchase agreement becomes less than the repurchase price (including
accrued interest), an Underlying Fund will direct the seller of the security to
deliver additional securities so that the market value of all securities subject
to the repurchase agreement equals or exceeds the repurchase price.  Certain
repurchase agreements which      

                                     B-59
<PAGE>
 
provide for settlement in more than seven days can be liquidated before the
nominal fixed term on seven days or less notice. Such repurchase agreements will
be regarded as liquid instruments.
    
  In addition, an Underlying Fund, together with other registered investment
companies having advisory agreements with the Adviser or its affiliates, may
transfer uninvested cash balances into a single joint account, the daily
aggregate balance of which will be invested in one or more repurchase
agreements.     

Reverse Repurchase Agreements

  Certain Underlying Funds may borrow money for temporary purposes by entering
into transactions called reverse repurchase agreements. Under these
arrangements, a Fund will sell portfolio securities to dealers in U.S.
Government Securities or members of the Federal Reserve System, with an
agreement to repurchase the security on an agreed date, price and interest
payment.  The Core Fixed Income, Global Income and High Yield Funds may also
enter into reverse repurchase agreements involving certain foreign government
securities. Reverse repurchase agreements involve the possible risk that the
value of portfolio securities a Fund relinquishes may decline below the price a
Fund must pay when the transaction closes. Borrowings may magnify the potential
for gain or loss on amounts invested resulting in an increase in the speculative
character of a Fund's outstanding shares.
    
     When a Fund enters into a reverse repurchase agreement, it segregates cash
or liquid assets that have a value equal to or greater than the repurchase
price. The account is then continuously monitored by its investment adviser to
make sure that an appropriate value is maintained. Reverse repurchase agreements
are considered to be borrowings under the Act.     

Restricted and Illiquid Securities
    
     The Underlying Funds may not invest more than 15% (10% in the case of
Financial Square Prime Obligations Fund) of their net assets in illiquid
investments, which include securities (both foreign and domestic) that are not
readily marketable, certain SMBS, certain municipal leases and participation
interests, certain over-the-counter options, repurchase agreements and time
deposits with a notice or demand period of more than seven days, and certain
restricted securities, unless it is determined, based upon a continuing review
of the trading markets for the specific instrument, that such instrument is
liquid.  The Trustees have adopted guidelines under which the Underlying Funds'
investment advisers determine and monitor the liquidity of the Underlying Funds'
portfolio securities.  This investment practice could have the effect of
increasing the level of illiquidity in an Underlying Fund to the extent that
qualified institutional buyers become for a time uninterested in purchasing
these instruments.     

     The purchase price and subsequent valuation of restricted securities may
reflect a discount from the price at which such securities trade when they are
not restricted, since the restriction may make them less liquid.  The amount of
the discount from the prevailing market price is expected to vary depending upon
the type of security, the character of the issuer, the party who will bear the
expenses of registering the restricted securities and prevailing supply and
demand conditions.

Portfolio Turnover     
    
     Each Underlying Fund may engage in active short-term trading to benefit
from yield disparities among different issues of securities or among the markets
for fixed-income securities, or for other reasons.  It is anticipated that the
portfolio turnover rate of each Fund will vary from year to year.     

                            INVESTMENT RESTRICTIONS
                                            
     The following investment restrictions have been adopted by the Trust as
fundamental policies that cannot be changed without the affirmative vote of the
holders of a majority (as defined in the Act) of the outstanding voting
securities of the affected Portfolio.  The investment objective of each
Portfolio and all other investment policies or practices of each Portfolio are
considered by the Trust not to be fundamental and accordingly may be changed
without shareholder approval.  For purposes of the Act, "majority" means the
lesser of (a) 67% or more of the shares of the Trust or a Portfolio present at a
meeting, if the holders of more than 50% of the outstanding shares of the Trust
or a Portfolio are present or represented by proxy, or (b) more than 50% of the
shares of the Trust or a Portfolio.  For purposes of the following limitations,
any limitation which involves a maximum percentage shall not be considered
violated unless an excess over the percentage occurs immediately after, and is
caused by, an acquisition or encumbrance of securities or assets of, or
borrowings by, a Portfolio.  With respect to the Portfolios' fundamental
investment restriction no. 3, asset coverage of at least 300% (as defined in the
Act), inclusive of any amounts borrowed, must be maintained at all times.     
    
     As a matter of fundamental policy, a Portfolio may not:     

          (1)  make any investment inconsistent with the Portfolio's
               classification as a diversified company under the Act;

          (2)  invest 25% or more of its total assets in the securities of one
               or more issuers conducting their principal business activities in
               the same industry (excluding investment companies and the U.S.
               Government or any of its agencies or instrumentalities).  (For
               the purposes of this restriction, state and municipal governments
               and their agencies, authorities and instrumentalities are not
               deemed to be industries; telephone companies are considered to be
               a separate industry from water, gas or electric utilities;
               personal credit finance companies and business credit finance
               companies are deemed to be separate industries; and wholly-owned
               finance companies are considered to be in the industry of their
               parents if their activities are primarily related to financing
               the activities of their parents.)  This restriction does not
               apply to investments in municipal securities which have been pre-
               refunded by the use of obligations of the U.S. government or any
               of its agencies or instrumentalities;

          (3)  borrow money, except (a) the Portfolio may borrow from banks (as
               defined in the Act) or through reverse repurchase agreements in
               amounts up to 33-1/3% of its total assets (including the amount
               borrowed), (b) the Portfolio may, to the extent permitted by

                                     B-61
<PAGE>
 
               applicable law, borrow up to an additional 5% of its total
               assets for temporary purposes, (c) the Portfolio may obtain such
               short-term credits as may be necessary for the clearance of
               purchases and sales of portfolio securities, (d) the Portfolio
               may purchase securities on margin to the extent permitted by
               applicable law and (e) the Portfolio may engage transactions in
               mortgage dollar rolls which are accounted for as financings;

          (4)  make loans, except through (a) the purchase of debt obligations
               in accordance with the Portfolio's investment objective and
               policies, (b) repurchase agreements with banks, brokers, dealers
               and other financial institutions and (c) loans of securities as
               permitted by applicable law;

          (5)  underwrite securities issued by others, except to the extent that
               the sale of portfolio securities by the Portfolio may be deemed
               to be an underwriting;

          (6)  purchase, hold or deal in real estate, although a Portfolio may
               purchase and sell securities that are secured by real estate or
               interests therein, securities of real estate investment trusts
               and mortgage-related securities and may hold and sell real estate
               acquired by a Portfolio as a result of the ownership of
               securities;

          (7)  invest in commodities or commodity contracts, except that the
               Portfolio may invest in currency and financial instruments and
               contracts that are commodities or commodity contracts;

          (8)  issue senior securities to the extent such issuance would violate
               applicable law.

     Notwithstanding any other fundamental investment restriction or policy,
each Portfolio may invest some or all of its assets in a single open-end
investment company or series thereof with substantially the same investment
objective, restrictions and policies as the Portfolio.

     In addition to the fundamental policies mentioned above, the Trustees have
adopted the following non-fundamental policies which can be changed or amended
by action of the Trustees without approval of shareholders.

     A Portfolio may not:

          (a)  Invest in companies for the purpose of exercising control or
               management (but this does not prevent a Portfolio from purchasing
               a controlling interest in one or more of the Underlying Funds
               consistent with its investment objective and policies).

          (b)  Invest more than 15% of the Portfolio's net assets in illiquid
               investments, including repurchase agreements maturing in more
               than seven days, securities which are not readily marketable and
               restricted 

                                     B-62
<PAGE>
 
               securities not eligible for resale pursuant to Rule 144A under
               the 1933 Act.

          (c)  Purchase additional securities if the Portfolio's borrowings
               (excluding covered mortgage dollar rolls) exceed 5% of its net
               assets.

          (d)  Make short sales of securities, except short sales against the
               box.

     The Underlying Funds in which the Portfolios may invest have adopted
certain investment restrictions which may be more or less restrictive than those
listed above, thereby allowing a Portfolio to participate in certain investment
strategies indirectly that are prohibited under the fundamental and non-
fundamental investment restrictions and policies listed above. The investment
restrictions of these Underlying Funds are set forth in their respective
Additional Statements.

                                   MANAGEMENT

     The Underlying Funds' investment advisers are able to draw on the
substantial research and market expertise of Goldman Sachs whose investment
research effort is one of the largest in the industry. With an annual equity
research budget approaching $200 million, the Goldman Sachs Global Investment
Research Department covers approximately 2,000 companies, including
approximately 1,000 U.S. corporations in 60 industries.  The in-depth
information and analyses generated by Goldman Sachs' research analysts are
available to the investment advisers.  For more than a decade, Goldman Sachs has
been among the top-ranked firms in Institutional Investor's annual "All-America
Research Team" survey.  In addition, many of Goldman Sachs' economists,
securities analysts, portfolio strategists and credit analysts have consistently
been highly ranked in respected industry surveys conducted in the U.S. and
abroad.  Goldman Sachs is also among the leading investment firms using
quantitative analytics (now used by a growing number of investors) to structure
and evaluate portfolios.     

     In managing the Underlying Funds, the Underlying Funds' investment advisers
have access to Goldman Sachs' economics research.  The Economics Research
Department conducts economic, financial 

                                     B-74
<PAGE>
 
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 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 Government Bond Market
1993-1995; International Economies 1986, 1988-1995; and Currency Movements
1986-1993.

     In structuring Adjustable Rate Government Fund's and Short Duration
Government Fund's respective securities portfolios, their investment adviser
will review the existing overall economic and mortgage market trends.  The
investment adviser will then study yield spreads, the implied volatility and the
shape of the yield curve.  The investment adviser will then apply this analysis
to a list of eligible securities that meet the respective Fund's investment
guidelines.  With respect to Adjustable Rate Government Fund, this analysis is
used to plan a two-part portfolio, which will consist of a "core" portfolio of
ARMs and a "relative value" portfolio of other mortgage assets that can enhance
portfolio returns and lower risk (such as investments in CMO floating-rate
tranches and interest only SMBS).
    
     With respect to Adjustable Rate Government Fund, Short Duration Government
Fund, Government Income Fund, Core Fixed Income Fund and High Yield Fund, the
applicable investment advisers expect to utilize Goldman Sachs' sophisticated
option-adjusted analytics to help make strategic asset allocations within the
markets for U.S. government, Mortgage-Backed and other securities and to employ
this technology periodically to re-evaluate the Funds' investments as market
conditions change.  Goldman Sachs has also developed a prepayment model designed
to estimate mortgage prepayments and cash flows under different interest rate
scenarios.  Because a Mortgage-Backed Security incorporates the borrower's right
to prepay the mortgage, the investment advisers use a sophisticated option-
adjusted spread (OAS) model to measure expected returns.  A security's OAS is a
function of the level and shape of the yield curve, volatility and the
particular investment adviser's expectation of how a change in interest rates
will affect prepayment levels.  Since the OAS model assumes a relationship
between prepayments and  interest rates, the investment advisers consider it a
better way to measure a security's expected return and absolute and relative
values than yield to maturity.  In using OAS technology, the investment advisers
will first evaluate the absolute level of a security's OAS considering its
liquidity and its interest rate, volatility and prepayment sensitivity.  The
investment advisers will then analyze its value relative to alternative
investments and to its own investments.  The investment advisers will also
measure a security's interest rate risk by computing an option adjusted duration
(OAD).  The investment advisers believe a security's OAD is a better measurement
of its price sensitivity than cash flow duration, which systematically misstates
portfolio duration.  The investment advisers also evaluate returns for different
mortgage market sectors and evaluate the credit risk of individual securities.
This sophisticated technical analysis allows the investment advisers to develop
portfolio and trading strategies using Mortgage-Backed Securities that are
believed to be superior investments on a risk-adjusted basis and which provide
the flexibility to meet the respective Funds' duration targets and cash flow
pattern requirements.     

     Because the OAS is adjusted for the differing characteristics of the
underlying securities, the OAS of different Mortgage-Backed Securities can be
compared directly as an indication of their relative value in the market.  The
investment advisers also expect to use OAS-based pricing methods to calculate
projected security returns under different, discrete interest rate scenarios,
and Goldman Sachs' proprietary 

                                     B-75
<PAGE>
 
prepayment model to generate yield estimates under these scenarios. The OAS,
scenario returns, expected returns, and yields of securities in the mortgage
market can be combined and analyzed in an optimal risk-return matching
framework.

     The investment advisers will use OAS analytics to choose what they believe
is an appropriate portfolio of investments for an Underlying Fund from a
universe of eligible investments.  In connection with initial portfolio
selections, in addition to using OAS analytics as an aid to meeting each Fund's
particular composition and performance targets, the investment advisers will
also take into account important market criteria like the available supply and
relative liquidity of various mortgage securities in structuring the portfolio.

     The Underlying Funds' investment advisers also expect to use OAS analytics
to evaluate the mortgage market on an ongoing basis.  Changes in the relative
value of various Mortgage-Backed Securities could suggest tactical trading
opportunities for the Underlying Funds.  The investment advisers will have
access to both current market analysis as well as historical information on the
relative value relationships among different Mortgage-Backed Securities.
Current market analysis and  historical information is available in the Goldman
Sachs database for most actively traded Mortgage-Backed Securities.

     Goldman Sachs has agreed to provide the Underlying Funds' investment
advisers, on a non-exclusive basis, use of its mortgage prepayment model, OAS
model and any other proprietary services which it now has or may develop, to the
extent such services are made available to other similar customers.  Use of
these services by the Underlying Funds' investment advisers with respect to an
Underlying Fund does not preclude Goldman Sachs from providing these services to
third parties or using such services as a basis for trading for its own account
or the account of others.

     The fixed-income research capabilities of Goldman Sachs available to the
Underlying Funds' investment advisers include the Goldman Sachs Fixed-Income
Research Department and the Credit Department.  The Fixed-Income Research
Department monitors developments in U.S. and foreign fixed-income markets,
assesses the outlooks for various sectors of the markets and provides relative
value comparisons, as well as analyzes trading opportunities within and across
market sectors.  The Fixed-Income Research Department is at the forefront in
developing and using computer-based tools for analyzing fixed-income securities
and markets, developing new fixed-income products and structuring portfolio
strategies for investment policy and tactical asset allocation decisions.  The
Credit Department tracks specific governments, regions and industries and from
time to time may review the credit quality of an Underlying Fund's investments.

     In allocating assets among foreign countries and currencies for the
Underlying Funds which can invest in foreign securities, the Underlying Funds'
investment advisers will have access to the Global Asset Allocation Model.  The
model is based on the observation that the prices of all financial assets,
including foreign currencies, will adjust until investors globally are
comfortable holding the pool of outstanding assets.  Using the model, the
investment advisers will estimate the total returns from each currency sector
which are consistent with the average investor holding a portfolio equal to the
market capitalization of the financial assets among those currency sectors.
These estimated equilibrium returns are then combined with the expectations of
Goldman Sachs' research professionals to produce an optimal currency and asset
allocation for the level of risk suitable for an Underlying Fund given its
investment objectives and criteria.

     The management agreements for the Portfolios and the Underlying Funds
provide that the Adviser (and its affiliates) may render similar services to
others as long as the services provided by them thereunder are not impaired
thereby.
    
     The Portfolios' management agreement was most recently approved by the
Trustees, including a majority of the Trustees who are not parties to the
management agreement or "interested persons" (as such term is defined in the
Act) of any party thereto (the "non-interested Trustees"), on April __, 1999
with respect to the Balanced Strategy, Growth and Income Strategy, Growth
Strategy and Aggressive Growth Strategy Fund, and January 22, 1999 with respect
to the Conservative Strategy Fund.  These arrangements were approved by the sole
shareholder of the Balanced Strategy, Growth and Income Strategy, Growth
Strategy and Aggressive Growth Strategy Portfolios on January 1, 1998, and of
the Conservative Strategy Portfolio on February 3, 1999 by consent action to
satisfy conditions imposed by the SEC in connection with the registration of
shares of the Portfolio.  The management agreement will remain in effect until
June 30, 2000 and from year to year thereafter provided such continuance is
specifically approved at least annually by (a) the vote of a majority of the
outstanding voting securities of such Portfolio or a majority of the Trustees,
and (b) the vote of a majority of the non-interested Trustees, cast in person at
a meeting called for the purpose of voting on such approval.  The management
agreement will terminate automatically with respect to a Portfolio if assigned
(as defined in the Act) and is terminable at any time without penalty by the
Trustees or by vote of a majority of the outstanding voting securities of the
affected Portfolio on 60 days' written notice to the Adviser and by the Adviser
on 60 days' written notice to the Trust.     

     Under the management agreement, the Adviser also: (i) supervises all non-
advisory operations of each Portfolio; (ii) provides personnel to perform such
executive, administrative and clerical services as are reasonably necessary to
provide effective administration of each Portfolio; (iii) arranges for at each
Portfolio's expense (a) the preparation of all required tax returns, (b) the
preparation and submission of reports to existing shareholders, (c) the periodic
updating of prospectuses and statements of additional information and (d) the
preparation of reports to be filed with the SEC and other regulatory
authorities; (iv) maintains each Portfolio's records; and (v) provides office
space and all necessary office equipment and services.

     Pursuant to the management agreement, the Advisers are entitled to receive
the contractual fees listed below, payable monthly of such Portfolio's average
daily net assets.

     Activities of Goldman Sachs and Its Affiliates and Other Accounts Managed
     -------------------------------------------------------------------------
by Goldman Sachs. The involvement of the Adviser and Goldman Sachs and their
- ----------------
affiliates in the management of, or their interest in, other accounts and other
activities of Goldman Sachs may present conflicts of interest with respect to
the Portfolios and the Underlying Funds or impede their investment activities.

     Goldman Sachs and its affiliates, including, without limitation, the
Adviser and its advisory affiliates, have proprietary interests in, and may
manage or advise with respect to, accounts or funds (including separate accounts
and other funds and collective investment vehicles) which have investment
objectives similar to those of the Portfolios and the Underlying Funds and/or
which engage in transactions in the same types of securities, currencies and
instruments. Goldman Sachs and its affiliates are major participants in the
global currency, equities, swap and fixed-income markets, in each case both on a
proprietary basis and for the accounts of customers. As such, Goldman Sachs and
its affiliates are actively engaged in transactions in the same securities,
currencies and instruments in which the Underlying Funds invest. Such activities
could affect the prices and availability of the securities, currencies and
instruments in which the Underlying Funds invest, which could have an adverse
impact on each Fund's (and, consequently, each Portfolio's) performance. Such
transactions, particularly in respect of proprietary accounts or customer
accounts other than those included in the Adviser's and its advisory affiliates'
asset management activities, will be executed independently of the Underlying
Funds' transactions and thus at prices or rates that may be more or less
favorable. When the Adviser and its advisory affiliates seek to purchase or sell
the same assets for their managed accounts, including the Underlying Funds, the
assets actually purchased or sold may be allocated among the accounts on a basis
determined in its good faith discretion to be equitable. In some cases, this
system may adversely affect the size or the price of the assets purchased or
sold for the Underlying Funds.

     From time to time, the Underlying Funds' activities may be restricted
because of regulatory restrictions applicable to Goldman Sachs and its
affiliates, and/or their internal policies designed to comply with such
restrictions. As a result, there may be periods, for example, when the Adviser
and/or its affiliates will not initiate or recommend certain types of
transactions in certain securities or instruments with respect to which the
Adviser and/or its affiliates are performing services or when position limits
have been reached.

     In connection with their management of the Underlying Funds, the Underlying
Funds' investment advisers may have access to certain fundamental analysis and
proprietary technical models developed by Goldman Sachs and other affiliates.
The investment advisers will not be under any obligation, however, to effect
transactions on behalf of the Underlying Funds in accordance with such analysis
and models. In addition, neither Goldman Sachs nor any of its affiliates will
have any obligation to make available any 

                                     B-78
<PAGE>
 
information regarding their proprietary activities or strategies, or the
activities or strategies used for other accounts managed by them, for the
benefit of the management of the Underlying Funds and it is not anticipated that
the investment advisers will have access to such information for the purpose of
managing the Underlying Funds. The proprietary activities or portfolio
strategies of Goldman Sachs and its affiliates or the activities or strategies
used for accounts managed by them or other customer accounts could conflict with
the transactions and strategies employed by the investment advisers in managing
the Underlying Funds.

       The results of each Underlying Fund's investment activities may differ
significantly from the results achieved by their investment advisers and
affiliates for their proprietary accounts or accounts (including investment
companies or collective investment vehicles) managed or advised by them.  It is
possible that Goldman Sachs and its affiliates and such other accounts will
achieve investment results which are substantially more or less favorable than
the results achieved by an Underlying Fund.  Moreover, it is possible that an
Underlying Fund will sustain losses during periods in which Goldman Sachs and
its affiliates achieve significant profits on their trading for proprietary or
other accounts.  The opposite result is also possible.

       The investment activities of Goldman Sachs and its affiliates for their
proprietary accounts and accounts under their management may also limit the
investment opportunities for the Underlying Funds in certain emerging markets in
which limitations are imposed upon the aggregate amount of investment, in the
aggregate or individual issuers, by affiliated foreign investors.

       An investment policy committee which may include partners of Goldman
Sachs and its affiliates may develop general policies regarding an Underlying
Fund's activities but will not be involved in the day-to-day management of such
Fund.  In such instances, those individuals may, as a result, obtain information
regarding the Underlying Fund's proposed investment activities which is not
generally available to the public.  In addition, by virtue of their affiliation
with Goldman Sachs, any such member of an investment policy committee will have
direct or indirect interests in the activities of Goldman Sachs and its
affiliates in securities currencies and investments similar to those in which
the Underlying Fund invests.

       In addition, certain principals and certain of the employees of the
Underlying Funds' investment advisers are also principals or employees of
Goldman Sachs or their affiliated entities.  As a result, the performance by
these principals and employees of their obligations to such other entities may
be a consideration of which investors in the Portfolios should be aware.

       The Underlying Funds' investment advisers may enter into transactions and
invest in currencies or instruments on behalf of an Underlying Fund in which
customers of Goldman Sachs serve as the counterparty, principal or issuer.  In
such cases, such party's interests in the transaction will be adverse to the
interests of an Underlying Fund, and such party may have no incentive to assure
that the Underlying Funds obtain the best possible prices or terms in connection
with the transactions.  Goldman Sachs and its affiliates may also create, write
or issue derivative instruments for customers of Goldman Sachs or its
affiliates, the underlying securities, currencies or instruments of which may be
those in which an Underlying Fund invests or which may be based on the
performance of an Underlying Fund.  The Underlying Funds may, subject to
applicable law, purchase investments which are the subject of an underwriting or
other distribution by Goldman Sachs or its affiliates and may also enter
transactions with other clients of Goldman Sachs or its affiliates where such
other clients have interests adverse to those of the Underlying Funds.  At
times, these activities may cause departments of Goldman Sachs or its affiliates
to give advice to clients that may cause these clients to take actions adverse
to the interests of the 

                                     B-79
<PAGE>
 
Portfolios. To the extent affiliated transactions are permitted, the Underlying
Funds will deal with Goldman Sachs and its affiliates on an arms-length basis.

       Each Underlying Fund will be required to establish business relationships
with its counterparties based on the Underlying Fund's own credit standing.
Neither Goldman Sachs nor its affiliates will have any obligation to allow their
credit to be used in connection with an Underlying Fund's establishment of its
business relationships, nor is it expected that an Underlying Fund's
counterparties will rely on the credit of Goldman Sachs or any of its affiliates
in evaluating the Underlying Fund's creditworthiness.

       From time to time, Goldman Sachs or any of its affiliates may, but is not
required to, purchase and hold shares of an Underlying Fund in order to increase
the assets of the Underlying Fund.  Increasing an Underlying Fund's assets may
enhance investment flexibility and diversification and may contribute to
economies of scale that tend to reduce the Underlying Fund's expense ratio.
Goldman Sachs reserves the right to redeem at any time some or all of the shares
of an Underlying Fund acquired for its own account.  A large redemption of
shares of an Underlying Fund by Goldman Sachs could significantly reduce the
asset size of the Underlying Fund, which might have an adverse effect on the
Underlying Fund's investment flexibility, portfolio diversification and expense
ratio.  Goldman Sachs will consider the effect of redemptions on an Underlying
Fund and other shareholders in deciding whether to redeem its shares.

       It is possible that an Underlying Fund's holdings will include securities
of entities for which Goldman Sachs performs investment banking services as well
as securities of entities in which Goldman Sachs makes a market.  From time to
time, Goldman Sachs' activities may limit the Underlying Funds' flexibility in
purchases and sales of securities.  When Goldman Sachs is engaged in an
underwriting or other distribution of securities of an entity, the Underlying
Funds' investment advisers may be prohibited from purchasing or recommending the
purchase of certain securities of that entity for the Underlying Funds.

Distributor and Transfer Agent
    
       Goldman Sachs serves as the exclusive Distributor of shares of the
Portfolios pursuant to a "best efforts" arrangement as provided by a
distribution agreement with the Trust on behalf of each Portfolio.  Shares of
the Portfolios are offered and sold on a continuous basis by Goldman Sachs,
acting as agent.  Pursuant to the distribution agreement, after the Portfolios'
Prospectus and periodic reports have been prepared, set in type and mailed to
shareholders, Goldman Sachs will pay for the printing and distribution of copies
thereof used in connection with the offering to prospective investors.  Goldman
Sachs will also pay for other supplementary sales literature and advertising
costs.  Goldman Sachs has entered into sales agreements with certain investment
dealers and financial  service firms (the "Authorized Dealers") to solicit
subscriptions for Class A, Class B and Class C Shares of each of the Portfolios
that offer such classes of shares.  Goldman Sachs receives a portion of the
sales load imposed on the sale, in the case of Class A Shares, or redemption in
the case of Class B and Class C Shares, of such Portfolio shares.     
    
       Goldman Sachs retained approximately the following commissions on sales
of Class A, Class B and Class C Shares during the period ended December 31:

     Goldman Sachs also serves as the Portfolios' transfer and dividend
disbursing agent. Under its transfer agency agreement with the Trust, Goldman
Sachs has undertaken with the Trust with respect to each Portfolio to (i) record
the issuance, transfer and redemption of shares, (ii) provide confirmations of
purchases and redemptions, and quarterly statements, as well as certain other
statements, (iii) provide certain information to the Trust's custodian and the
relevant subcustodian in connection with redemptions, (iv) provide dividend
crediting and certain disbursing agent services, (v) maintain shareholder
accounts, (vi) provide certain state Blue Sky and other information, (vii)
provide shareholders and certain regulatory authorities with tax-related
information, (viii) respond to shareholder inquiries, and (ix) render certain
other miscellaneous services. For its transfer agency services, Goldman Sachs is
entitled to receive a transfer agency fee equal, on an annual basis of 0.04% of
average daily net assets with respect to each Portfolio's Institutional and
Service Shares and 0.19% of average daily net assets with respect to each
Portfolio's Class A, Class B and Class C Shares.     
    
     As compensation for the services rendered to the Portfolios' by Goldman
Sachs as transfer and dividend disbursing agent and the assumption by Goldman
Sachs of the expenses related thereto, Goldman Sachs is entitled to receive fees

Expenses      
     
     The Trust, on behalf of each Portfolio, is responsible for the payment of
each Portfolio's respective expenses. The expenses include, without limitation,
the fees payable to the Adviser, service fees paid to Service Organizations, the
fees and expenses payable to the Trust's custodian and subcustodians, transfer
agent fees, brokerage fees and commissions, filing fees for the registration or
qualification of the Trust's shares under federal or state securities laws,
expenses of the organization of the Trust, fees and expenses incurred by the
Trust in connection with membership in investment company organizations, taxes,
interest, costs of liability insurance, fidelity bonds or indemnification, any
costs, expenses or losses arising out of any liability of, or claim for damages
or other relief asserted against, the Trust for violation of any law, legal and
auditing fees and expenses (including the cost of legal and certain accounting
services rendered by employees of GSAM and Goldman Sachs with respect to the
Trust), expenses of preparing and setting in type prospectuses, statements of
additional information, proxy material, reports and notices and the printing and
distributing of the same to the Trust's shareholders and regulatory authorities,
any expenses assumed by a Portfolio pursuant to its distribution and service
plans, compensation and expenses of its "non-interested" Trustees and
extraordinary expenses, if any, incurred by the Trust. Except for fees under any
distribution and service plans applicable to a particular class and transfer
agency fees, all Portfolio expenses are borne on a non-class specific basis.

The Adviser has voluntarily agreed to reduce or limit certain "Other Expenses"
(excluding management, distribution and service fees, taxes, transfer agency
fees, interest, brokerage, litigation, indemnification costs and other
extraordinary expenses) for the Portfolios to the extent such expenses exceed

                      PORTFOLIO TRANSACTIONS AND BROKERAGE
                                            
     The Adviser is responsible with respect to the Portfolios (and the
particular investment adviser is responsible with respect to the Underlying
Funds) for decisions to buy and sell securities for the Underlying Fund, the
selection of brokers and dealers to effect the transactions and the negotiation
of brokerage commissions, if any. Purchases and sales of securities on a
securities exchange are effected through brokers who charge a commission for
their services. Orders may be directed to any broker including, to the extent
and in the manner permitted by applicable law, Goldman Sachs.     

     In the over-the-counter market, securities are generally traded on a "net"
basis with dealers acting as principal for their own accounts without a stated
commission, although the price of a security usually includes a profit to the
dealer. In underwritten offerings, securities are purchased at a fixed price
which includes an amount of compensation to the underwriter, generally referred
to as the underwriter's concession or discount. On occasion, certain money
market instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid.

     The portfolio transactions for the Underlying Fixed-Income Funds are
generally effected at a net price without a broker's commission (i.e., a dealer
is dealing with an Underlying Fund as principal and receives compensation equal
to the spread between the dealer's cost for a given security and the resale
price of such security). In certain foreign countries, debt securities are
traded on exchanges at fixed commission rates.
    
     In placing orders for portfolio securities of an Underlying Fund, the
Underlying Funds' investment advisers are generally required to give primary
consideration to obtaining the most favorable price and net price available.
This means that an investment adviser will seek to execute each transaction at a
price and commission, if any, which provides the most favorable total cost or
proceeds reasonably attainable in the circumstances. As permitted by Section
28(e) of the Securities Exchange Act of 1934, the Underlying Fund may pay a
broker which provides brokerage and research services an amount of disclosed
commission in excess of the commission which another broker would have charged
for effecting that transaction. Such practice is subject to a good faith
determination by the Trustees that such commission is reasonable in light of the
services provided and to such policies as the Trustees may adopt from time to
time. While the Underlying Funds' investment advisers generally seek reasonably
competitive spreads or commissions, an Underlying Fund will not necessarily be
paying the lowest spread     

                                     B-83
<PAGE>
 
or commission available. Within the framework of this policy, the investment
advisers will consider research and investment services provided by brokers or
dealers who effect or are parties to portfolio transactions of an Underlying
Fund, the investment advisers and their affiliates, or their other clients. Such
research and investment services are those which brokerage houses customarily
provide to institutional investors and include research reports on particular
industries and companies, economic surveys and analyses, recommendations as to
specific securities and other products or services (e.g., quotation equipment
and computer related costs and expenses), advice concerning the value of
securities, the advisability of investing in, purchasing or selling securities,
the availability of securities or the purchasers or sellers of securities,
furnishing analyses and reports concerning issuers, industries, securities,
economic factors and trends, portfolio strategy and performance of accounts,
effecting securities transactions and performing functions incidental thereto
(such as clearance and settlement) and providing lawful and appropriate
assistance to the investment advisers in the performance of their
decision-making responsibilities. Such services are used by the investment
advisers in connection with all of their investment activities, and some of such
services obtained in connection with the execution of transactions for an
Underlying Fund may be used in managing other investment accounts. Conversely,
brokers furnishing such services may be selected for the execution of
transactions of such other accounts, whose aggregate assets are far larger than
those of an Underlying Fund, and the services furnished by such brokers may be
used by the investment advisers in providing management services for the Trust.

     In circumstances where two or more broker-dealers offer comparable prices
and execution capability, preference may be given to a broker-dealer which has
sold shares of an Underlying Fund as well as shares of other investment
companies or accounts managed by the Underlying Funds' investment advisers. This
policy does not imply a commitment to execute all portfolio transactions through
all broker-dealers that sell shares of the Underlying Fund.

     On occasions when an Underlying Fund's investment adviser deems the
purchase or sale of a security to be in the best interest of an Underlying Fund
as well as its other customers (including any other fund or other investment
company or advisory account for which such investment adviser acts as investment
adviser or subadviser), the investment adviser, to the extent permitted by
applicable laws and regulations, may aggregate the securities to be sold or
purchased for the Underlying Fund with those to be sold or purchased for such
other customers in order to obtain the best net price and most favorable
execution under the circumstances. In such event, allocation of the securities
so purchased or sold, as well as the expenses incurred in the transaction, will
be made by the particular investment adviser in the manner it considers to be
equitable and consistent with its fiduciary obligations to such Fund and such
other customers. In some instances, this procedure may adversely affect the
price and size of the position obtainable for an Underlying Fund.

     Commission rates in the U.S. are established pursuant to negotiations with
the broker based on the quality and quantity of execution services provided by
the broker in the light of generally prevailing rates. The allocation of orders
among brokers and the commission rates paid are reviewed periodically by the
Trustees.
    
     Subject to the above considerations, the Underlying Funds' investment
advisers may use Goldman Sachs as a broker for an Underlying Fund. In order for
Goldman Sachs to effect any portfolio transactions for an Underlying Fund, the
commissions, fees or other remuneration received by Goldman Sachs must be
reasonable and fair compared to the commissions, fees or other remuneration paid
to other brokers in connection with comparable transactions involving similar
instruments being purchased or sold on an 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      

                                     B-84
<PAGE>
 
commensurate arm's-length transaction. Furthermore, the Trustees, including a
majority of the Trustees who are not "interested" Trustees, have adopted
procedures which are reasonably designed to provide that any commissions, fees
or other remuneration paid to Goldman Sachs are consistent with the foregoing
standard. Brokerage transactions with Goldman Sachs are also subject to such
fiduciary standards as may be imposed upon Goldman Sachs by applicable law.
    
     [During the fiscal year ended December 31, 1998, the Portfolios acquired
and sold securities of their regular broker-dealers: [complete] At December 21,
1998, the Portfolios held no securities of their regular broker-dealers as
defined in Rule 10b-1 under the Act or their parents.]     

                                NET ASSET VALUE
                                            
     Under the Act, the Trustees are responsible for determining in good faith
the fair value of securities of each Portfolio. In accordance with procedures
adopted by the Trustees, the net asset value per share of each class of each
Portfolio is calculated by determining the value of the net assets attributed to
each class of that Portfolio and dividing by the number of outstanding shares of
that class. All securities are valued as of the close of regular trading on the
New York Stock Exchange (normally, but not always, 4:00 p.m. New York time) on
each Business Day. The term "Business Day" means any day the New York Stock
Exchange is open for trading which is Monday through Friday except for holidays.
The New York Stock Exchange is closed on the following holidays: New Year's Day,
Martin Luther King, Jr. Day, Presidents' Day (observed), Good Friday, Memorial
Day (observed), Independence Day (observed), Labor Day, Thanksgiving Day and
Christmas Day (observed).     

     In the event that the New York Stock Exchange or the national securities
exchange on which stock options are traded adopt different trading hours on
either a permanent or temporary basis, the Trustees will reconsider the time at
which net asset value is computed. In addition, each Portfolio may compute its
net asset value as of any time permitted pursuant to any exemption, order or
statement of the SEC or its staff.

     In determining the net asset value of a Portfolio, the net asset value of
the Underlying Funds' shares held by the Portfolio will be their net asset value
at the time of computation. Financial Square Prime Obligations Fund values all
of its portfolio securities using the amortized cost valuation method pursuant
to Rule 2a-7 under the Act. Other portfolio securities for which accurate market
quotations are available are valued by a Portfolio or Underlying Fund as
follows: (a) securities listed on any U.S. or foreign stock exchange or on the
National Association of Securities Dealers Automated Quotations System
("NASDAQ") will be valued at the last sale price on the exchange or system in
which they are principally traded, on the valuation date. If there is no sale on
the valuation day, securities traded will be valued at the 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 Underlying Fund's
net asset value, the securities will be valued at the mean between the bid and
the 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 sections (a) or (b) hereof, 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., Bloonberg, EJV, Reuters or
Standard & Poor's); (e) fixed-income securities for which

                                     B-85
<PAGE>
 
quotations are not readily available are valued by the investment adviser based
on valuation models that take into account spread and daily yield changes on
government securities in the appropriate market (i.e. matrix pricing); (f) debt
securities with a remaining maturity of 60 days or less are valued by the
particular investment adviser at amortized cost, which the Trustees have
determined to approximate fair value; and (g) all other instruments, including
those for which a pricing service supplies no exchange quotation or a quotation
that is believed by the portfolio manager/trader to be inaccurate, will be
valued at fair value in accordance with the valuation procedures approved by the
Board of Trustees.

          The value of all assets and liabilities expressed in foreign
currencies will be converted into U.S. dollar values at current exchange rates
of such currencies against U.S. dollars last quoted by any major bank.  If such
quotations are not available, the rate of exchange will be determined in good
faith by or under procedures established by the Board of Trustees.
    
          Generally, trading in securities on European and Far Eastern
securities exchanges and on over-the-counter markets is substantially completed
at various times prior to the close of business on each Business Day in New York
(i.e., a day on which the New York Stock Exchange is open for trading).  In
addition, European or Far Eastern securities trading generally or in a
particular country or countries may not take place on all Business Days in New
York.  Furthermore, trading takes place in various foreign markets on days which
are not Business Days in New York and days on which the Underlying Funds' net
asset values are not calculated.  Such calculation does not take place
contemporaneously with the determination of the prices of the majority of the
portfolio securities used in such calculation.  The impact of events that occur
after the publication of market quotations used by a Fund to price its
securities but before the close of regular trading on the New York Stock
Exchange will normally not be reflected in an Underlying Fund's next determined
net asset value unless the Trust, in its discretion, makes an adjustment in
light of the nature and materiality of the event, its effect on Fund operations
and other relevant factors.     

          The proceeds received by each Portfolio and each other series of the
Trust from the issue or sale of its shares, and all net investment income,
realized and unrealized gain and proceeds thereof, subject only to the rights of
creditors, will be specifically allocated to such Portfolio and constitute the
underlying assets of that Portfolio or series.  The underlying assets of each
Portfolio will be segregated on the books of account, and will be charged with
the liabilities in respect of such Portfolio and with a share of the general
liabilities of the Trust. Expenses of the Trust with respect to the Portfolios
and the other series of the Trust are generally allocated in proportion to the
net asset values of the respective Portfolios or series except where allocations
of direct expenses can otherwise be fairly made.


                            PERFORMANCE INFORMATION
                                        
          A Portfolio may from time to time quote or otherwise use total return,
yield and/or distribution rate information in advertisements, shareholder
reports or sales literature.  Average annual total return and yield are computed
pursuant to formulas specified by the SEC.

          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 

                                     B-86
<PAGE>
 
period. The calculation of net investment income for these purposes may differ
from the net investment income determined for accounting purposes.

          The distribution rate for a specified period is calculated by
annualizing distributions of net investment income for such period and dividing
this amount by the net asset value per share or maximum public offering price on
the last day of the period.

          Average annual total return for a specified period is derived by
calculating the actual dollar amount of the investment return on a $1,000
investment made at the maximum public offering price applicable to the relevant
class (i.e., net asset value in the case of each class other than Class A) at
the beginning of the period, and then calculating the annual compounded rate of
return which would produce that amount, assuming a redemption (and payment of
any contingent deferred sales charge) at the end of the period.  This
calculation assumes a complete redemption of the investment.  It also assumes
that all dividends and distributions are reinvested at net asset value on the
reinvestment dates during the period.

          Year-by-year total return and cumulative total return for a specified
period are each derived by calculating the percentage rate required to make a
$1,000 investment (made at the maximum public offering price with all
distributions reinvested) at the beginning of such period equal to the actual
total value of such investment at the end of such period.
    
          Total return calculations for Class A Shares reflect the effect of
paying the maximum initial sales charge.  Investment at a lower sales charge
would result in higher performance figures.  Total return calculations for Class
B and Class C Shares reflect deduction of the applicable CDSC imposed upon
redemption of Class B and Class C Shares held for the applicable period.  Each
Portfolio may also from time to time advertise total return on a cumulative,
average, year-by-year or other basis for various specified periods by means of
quotations, charts, graphs or schedules.  In addition, each Portfolio may
furnish total return calculations based on investments at various sales charge
levels or at NAV.  Any performance information which is based on a Portfolio's
net asset value per share would be reduced if any applicable sales charge were
taken into account.  In addition to the above, each Portfolio may from time to
time advertise its performance relative to certain averages, performance
rankings, indices, other information prepared by recognized mutual fund
statistical services and investments for which reliable performance information
is available.  The Portfolios' performance quotations do not reflect any fees
charged by an Authorized Dealer, Service Organization or other financial
intermediary to its customer accounts in connection with investments in the
Portfolios.     
    
          Thirty-day yield, distribution rate and average annual total return
are calculated separately for each class of shares of each Portfolio.  Each
class of shares of each Portfolio is subject to different fees and expenses and
may have different returns for the same period.     
    
          Occasionally, statistics may be used to specify Portfolio volatility
or risk.  Measures of volatility or risk are generally used to compare a
Portfolio's net asset value or performance relative to a market index.  One
measure of volatility is beta.  Beta is the volatility of a Portfolio relative
to the total market.  A beta of more than 1.00 indicates volatility greater than
the market, and a beta of less than 1.00 indicates volatility less than the
market.  Another measure of volatility or risk is standard deviation.  Standard
deviation is used to measure variability of net asset value or total return
around an average, over a specified period of time.  The premise is that greater
volatility connotes greater risk undertaken in achieving performance.

discussion of certain attributes or benefits to be derived by an investment in a
Portfolio.  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 Portfolio's investments and discussions
of a Portfolio's current asset allocation.

          In addition, from time to time, advertisements or information may
include a discussion of asset allocation models developed by the Adviser 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 the Adviser'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 Portfolio's performance data will be based on historical results and
will not be intended to indicate future performance.  A Portfolio's total
return, yield and distribution rate will vary based on market conditions,
portfolio expenses, portfolio investments and other factors.  The value of a
Portfolio's shares will fluctuate and an investor's shares may be worth more or
less than their original cost upon redemption.

          The Trust may, at its discretion, from time to time make a list of a
Portfolio's holdings available to investors upon request.


                              SHARES OF THE TRUST
                                            
          Each Portfolio is a series of Goldman Sachs Trust, which was formed
under the laws of the state of Delaware on January 28, 1997.  The Trustees have
authority under the Trust's Declaration of Trust to create and classify shares
of beneficial interest in separate series, without further action by
shareholders.  The Trustees also have authority to classify and reclassify the
shares of the Portfolios into one or more classes of shares.  As of the date of
this Additional Statement, the Trustees have authorized the issuance of five
classes of shares in each Portfolio:  Institutional Shares, Service Shares,
Class A Shares, Class B Shares and Class C Shares.     

          Each Institutional Share, Service Share, Class A Share, Class B Share
and Class C Share of a Portfolio represents a proportionate interest in the
assets belonging to the applicable class of the Portfolio.  All expenses of a
Portfolio are borne at the same rate by each class of shares, except that fees
under Service Plan are borne exclusively by Service Shares, fees under the
Distribution and Service Plan are borne exclusively by Class A Shares, Class B
Shares or Class C Shares, and transfer agency fees may be borne at different
rates by different share classes.  The Trustees may determine in the future that
it is appropriate to 

                                     B-96
<PAGE>
     
allocate other expenses differently between classes of shares and may do so to
the extent consistent with the rules of the SEC and positions of the Internal
Revenue Service. Each class of shares may have different minimum investment
requirements and be entitled to different shareholder services. With limited
exceptions, shares of a class may only be exchanged for shares of the same or an
equivalent class of another series. See "Shareholder Guide" in the 
Prospectus.     

          Institutional Shares may be purchased at net asset value without a
sales charge for accounts in the name of an investor or institution that is not
compensated by a Portfolio under a Plan for services provided to the
institution's customers.

          Service Shares may be purchased at net asset value without a sales
charge for accounts held in the name of an institution that, directly or
indirectly, provides certain account administration and shareholder liaison
services to its customers, including maintenance of account records and
processing orders to purchase, redeem and exchange Service Shares.  Service
Shares bear the cost of account administration fees at the annual rate of up to
0.50% of the average daily net assets of the Portfolio attributable to Service
Shares.
    
          Class A Shares are sold, with an initial sales charge, through brokers
and dealers who are members of the National Association of Securities Dealers,
Inc. and certain other financial service firms that have sales agreements with
Goldman Sachs.  Class A Shares of the Portfolios bear the cost of distribution
(Rule 12b-1) fees at the aggregate rate of up to 0.25% of the average daily net
assets of such Class A Shares.  With respect to Class A Shares, the Distributor
at its discretion may use compensation for distribution services paid under the
Distribution and Services Plan for personal and account maintenance services and
expenses so long as such total compensation under the Plan does not exceed the
maximum cap on "service fees" imposed by the NASD.     
    
          Class B Shares and Class C Shares of the Portfolios are sold subject
to a contingent deferred sales charge through brokers and dealers who are
members of the National Association of Securities Dealers, Inc. and certain
other financial services firms that have sales arrangements with Goldman Sachs.
Class B Shares and Class C Shares bear the cost of distribution (Rule 12b-1)
fees at the aggregate rate of up to 0.75% of the average daily net assets
attributed to Class B Shares and Class C Shares.  Class B Shares and Class C
Shares also bear the cost of a service fee at an annual rate of up to 0.25% of
the average daily net assets attributed to Class B Shares and Class C 
Shares.     

          It is possible that an institution or its affiliate may offer
different classes of shares (i.e., Institutional, Service, Class A, Class B and
Class C Shares) to its customers and thus receive different compensation with
respect to different classes of shares of each Portfolio.  Dividends paid by
each Portfolio, if any, with respect to each class of shares will be calculated
in the same manner, at the same time on the same day and will be in the same
amount, except for differences caused by the differences in expenses discussed
above. Similarly, the net asset value per share may differ depending upon the
class of shares purchased.

          Certain aspects of the shares may be altered after advance notice to
shareholders if it is deemed necessary in order to satisfy certain tax
regulatory requirements.

          When issued, shares are fully paid and non-assessable.  In the event
of liquidation, shareholders are entitled to share pro rata in the net assets of
the applicable class of the relevant Portfolio available for distribution to
such shareholders.  All shares are freely transferable and have no preemptive,
subscription or conversion rights.
    
          In the interest of economy and convenience, the Trust does not issue
certificates representing the Portfolios' shares.  Instead, the Transfer Agent
maintains a record of each shareholder's ownership.  Each shareholder receives
confirmation of purchase and redemption orders from the Transfer Agent.
Portfolio shares and any dividends and distributions paid by the Portfolios are
reflected in account statements from the Transfer Agent.

Aggressive Growth Strategy Portfolio's outstanding Class C shares.
    
          The Act requires that where more than one class or series of shares
exists, each class or series must be preferred over all other classes or series
in respect to assets specifically allocated to such class or series.  In
addition, Rule 18f-2 under the Act provides that any 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.       

                                     B-98

However, Rule 18f-2 exempts the selection of independent public accountants, the
approval of principal distribution contracts and the election of trustees from
the separate voting requirements of Rule 18f-2.
    
          The Trust is not required to hold annual meetings of shareholders and
does not intend to hold such meetings.  In the event that a meeting of
shareholders is held, each share of the Trust will be entitled, as determined by
the Trustees, either to one vote for each share or to one vote for each dollar
of net asset value represented by such shares on all matters presented to
shareholders including the elections of Trustees (this method of voting being
referred to as "dollar based voting").  However, to the extent required by the
Act or otherwise determined by the Trustees, series and classes of the Trust
will vote separately from each other.  Shareholders of the Trust do not have
cumulative voting rights in the election of Trustees.  Meetings of shareholders
of the Trust, or any series or class thereof, may be called by the Trustees,
certain officers or upon the written request of holders of 10% or more of the
shares entitled to vote at such meetings.  The Trustees will call a special
meeting of shareholders for the purpose of electing Trustees if, at any time,
less than a majority of Trustees holding office at the time were elected by
shareholders.  The shareholders of the Trust will have voting rights only with
respect to the limited number of matters specified in the Declaration of Trust
and such other matters as the Trustees may determine or may be required by 
law.     

          The Declaration of Trust provides for indemnification of Trustees,
officers, employees and agents of the Trust unless the recipient is adjudicated
(i) to be liable by reason of willful misfeasance, bad faith, gross negligence
or reckless disregard of the duties involved in the conduct of such person's
office or (ii) not to have acted in good faith in the reasonable belief that
such person's actions were in the best interest of the Trust.  The Declaration
of Trust provides that, if any shareholder or former shareholder of any series
is held personally liable solely by reason of being or having been a shareholder
and not because of the shareholder's acts or omissions or for some other reason,
the shareholder or former shareholder (or heirs, executors, administrators,
legal representatives or general successors) shall be held harmless from and
indemnified against all loss and expense arising from such liability.  The
Trust, acting on behalf of any affected series, must, upon request by such
shareholder, assume the defense of any claim made against such shareholder for
any act or obligation of the series and satisfy any judgment thereon from the
assets of the series.

          The Declaration of Trust permits the termination of the Trust or of
any series or class of the Trust (i) by a majority of the affected shareholders
at a meeting of shareholders of the Trust, series or class; or (ii) by a
majority of the Trustees without shareholder approval if the Trustees determine
that such action is in the best interest of the Trust, series or its respective
shareholders. The factors and events that the Trustees may take into account in
making such determination include (i) the inability of the Trust or any
successor series or class to maintain its assets at an appropriate size; (ii)
changes in laws or regulations governing the Trust, series or class or affecting
assets of the type in which it invests; or (iii) economic developments or trends
having a significant adverse impact on their business or operations.

          The Declaration of Trust authorizes the Trustees without shareholder
approval to cause the Trust, or any series thereof, to merge or consolidate with
any corporation, association, trust or other organization or sell or exchange
all or substantially all of the property belonging to the Trust or any series
thereof. In addition, the Trustees, without 

                                     B-99
<PAGE>
 
shareholder approval, may adopt a master-feeder structure by investing all or a
portion of the assets of a series of the Trust in the securities of another
open-end investment company with substantially the same investment objective,
restrictions and policies.

          The Declaration of Trust permits the Trustees to amend the Declaration
of Trust without a shareholder vote. However, shareholders of the Trust have the
right to vote on any amendment (i) that would adversely affect the voting rights
of shareholders; (ii) that is required by law to be approved by shareholders;
(iii) that would amend the provisions of the Declaration of Trust regarding
amendments and supplements thereto; or (iv) that the Trustees determine to
submit to shareholders.

          The Trustees may appoint separate Trustees with respect to one or more
series or classes of the Trust's shares (the "Series Trustees"). Series Trustees
may, but are not required to, serve as Trustees of the Trust or any other series
or class of the Trust. The Series Trustees have, to the exclusion of any other
Trustees of the Delaware Trust, all the powers and authorities of Trustees under
the Trust Instrument with respect to any other series or class.

Shareholder and Trustee Liability

          Under Delaware law, the shareholders of the Portfolios are not
generally subject to liability for the debts or obligations of the Trust.
Similarly, Delaware law provides that a series of the Trust will not be liable
for the debts or obligations of any other series of the Trust. However, no
similar statutory or other authority limiting business trust shareholder
liability exists in other states.  As a result, to the extent that a Delaware
business trust or a shareholder is subject to the jurisdiction of courts of such
other states, the courts may not apply Delaware law and may thereby subject the
Delaware business trust shareholders to liability.  To guard this risk, the
Declaration of Trust contains an express disclaimer of shareholder liability for
acts or obligations of a Portfolio.  Notice of such disclaimer will normally be
given in each agreement, obligation or instrument entered into or executed by a
series or the Trustees.  The Declaration of Trust provides for indemnification
by the relevant Portfolio for all loss suffered by a shareholder as a result of
an obligation of the series.  The Declaration of Trust also provides that a
series shall, upon request, assume the defense of any claim made against any
shareholder for any act or obligation of the series and satisfy any judgment
thereon.  In view of the above, the risk of personal liability of shareholders
of a Delaware business trust is remote.

          In addition to the requirements under Delaware law, the Declaration of
Trust provides that shareholders of a series may bring a derivative action on
behalf of the series only if the following conditions are met: (a) shareholders
eligible to bring such derivative action under Delaware law who hold at least
10% of the outstanding shares of the series, or 10% of the outstanding shares of
the class to which such action relates, shall join in the request for the
Trustees to commence such action; and (b) the Trustees must be afforded a
reasonable amount of time to consider such shareholder request and to
investigate the basis and to employ other advisers in considering the merits of
the request and shall require an undertaking by the shareholders making such
request to reimburse the Portfolio for the expense of any such advisers in the
event that the Trustees determine not to bring such action.

                                     B-100
<PAGE>
 
          The Declaration of Trust further provides that the Trustees will not
be liable for errors of judgment or mistakes of fact or law, but nothing in the
Declaration of Trust protects a Trustee against liability to which he or she
would otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties involved in the conduct of his
or her office.


                                    TAXATION
                                            
          The following is a summary of the principal U.S. federal income, and
certain state and local, tax considerations regarding the purchase, ownership
and disposition of shares in each Portfolio.  This summary does not address
special tax rules applicable to certain classes of investors, such as tax-exempt
entities, insurance companies and financial institutions.  Each prospective
shareholder is urged to consult his or her own tax adviser with respect to the
specific federal, state, local and foreign tax consequences of investing in each
Portfolio.  The summary is based on the laws in effect on the date of this
Additional Statement, which are subject to change.     

General
    
          Each Portfolio is a separate taxable entity.  Each of the Portfolios
intends to qualify for each taxable year as a regulated investment company under
Subchapter M of the Internal Revenue Code, as amended (the "Code").  To qualify
as such, a Fund must satisfy certain requirements relating to the sources of its
income, diversification of its assets and distribution of its income to
shareholders.  As a regulated investment company, a Fund will not be subject to
federal income or excise tax on any net investment income and net realized
capital gains that are distributed to its shareholders in accordance with
certain timing requirements of the Code.     

          Qualification as a regulated investment company under the Code
requires, among other things, that (a) a Portfolio derive at least 90% of its
gross income for its taxable year from dividends, interest, payments with
respect to securities loans and gains from the sale or other disposition of
stocks or securities or foreign currencies, or other income (including but not
limited to gains from options, futures, and forward contracts) derived with
respect to its business of investing in such stock, securities or currencies
(the "90% gross income test"); and (b) such Portfolio diversify its holdings so
that, at the close of each quarter of its taxable year, (i) at least 50% of the
market value of such Portfolio's total (gross) assets is comprised of cash, cash
items, U.S. Government securities, securities of other regulated investment
companies and other securities limited in respect of any one issuer to an amount
not greater in value than 5% of the value of such Portfolio's total assets and
to not more than 10% of the outstanding voting securities of such issuer, and
(ii) not more than 25% of the value of its total (gross) assets is invested in
the securities of any one issuer (other than U.S. Government securities and
securities of other regulated investment companies) or two or more issuers
controlled by the Portfolio and engaged in the same, similar or related trades
or businesses.

          If a Portfolio complies with such provisions, then in any taxable year
in which such Portfolio distributes, in compliance with the Code's timing and
other requirements, at least 

                                     B-101
<PAGE>
 
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 Portfolio (but not its shareholders) will be relieved of
federal income tax on any income of the Portfolio, including long- term capital
gains, distributed to shareholders. In this connection, dividends received by a
Portfolio from an Underlying Fund, other than capital gain distributions, are
treated as ordinary income to the Portfolio. Distributions from an Underlying
Fund designated as capital gain distributions are treated as long-term capital
gains. Such long-term capital gain will generally be 20% rate gain. In addition,
upon the sale or other disposition by a Portfolio of shares of an Underlying
Fund or other investment, the Portfolio will generally realize a capital gain or
loss which will be long-term or short-term, generally depending upon the
Portfolio's holding period.

          If a Portfolio retains any investment company taxable income or "net
capital gain" (the excess of net long-term capital gain over net short-term
capital loss), it will be subject to a tax at regular corporate rates on the
amount retained.  If a Portfolio retains any net capital gain, the Portfolio may
designate the retained amount as undistributed capital gains in a notice to its
shareholders who, if subject to U.S. federal income tax on long-term capital
gains, (i) will be required to include in income for federal income tax
purposes, as long-term rate capital gain, as the case may be, their shares of
such undistributed amount, and (ii) will be entitled to credit their
proportionate shares of the tax paid by the Portfolio against their U.S. federal
income tax liabilities, if any, and to claim refunds to the extent the credit
exceeds such liabilities.  For U.S. federal income tax purposes, the tax basis
of shares owned by a shareholder of the Portfolio will be increased by an amount
equal to a percentage of the amount of undistributed net capital gain included
in the shareholder's gross income.  Each Portfolio intends to distribute for
each taxable year to its shareholders all or substantially all of its investment
company taxable income, net capital gain and any net tax-exempt interest.
Exchange control or other foreign laws, regulations or practices may restrict
repatriation of investment income, capital or the proceeds of securities sales
by foreign investors such as the CORE International Equity, International
Equity, European Equity, Japanese Equity, International Small Cap, Emerging
Markets Equity, Asia Growth or Global Income Funds and may therefore make it
more difficult for such a Fund to satisfy the distribution requirements
described above, as well as the excise tax distribution requirements described
below.  However, each Fund generally expects to be able to obtain sufficient
cash to satisfy such requirements from new investors, the sale of securities or
other sources.  If for any taxable year a Portfolio does not qualify as a
regulated investment company, it will be taxed on all of its investment company
taxable income and net capital gain at corporate rates, and its distributions to
shareholders will be taxable as ordinary dividends to the extent of its current
and accumulated earnings and profits.

          In order to avoid a 4% federal excise tax, each Portfolio must
distribute (or be deemed to have distributed) by December 31 of each calendar
year at least 98% of its taxable ordinary income for such year, at least 98% of
the excess of its capital gains over its capital losses (generally computed on
the basis of the one-year period ending on October 31 of such year), and all
taxable ordinary income and the excess of capital gains over capital losses for
the previous year that were not distributed for such year and on which the
Portfolio paid no 

                                     B-102
<PAGE>
 
federal income tax. For federal income tax purposes, dividends declared by a
Portfolio 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 Portfolios anticipate that they will generally make timely distributions of
income and capital gains in compliance with these requirements so that they will
generally not be required to pay the excise tax. For federal income tax
purposes, each Portfolio is permitted to carry forward a net capital loss in any
year to offset its own capital gains, if any, during the eight years following
the year of the loss.

          Gains and losses on the sale, lapse, or other termination of options
and futures contracts, options thereon and certain forward contracts (except
certain foreign currency options, forward contracts and futures contracts) will
generally be treated as capital gains and losses.  Certain of the futures
contracts, forward contracts and options held by an Underlying Fund will be
required to be "marked-to-market" for federal income tax purposes, that is,
treated as having been sold at their fair market value on the last day of the
Fund's taxable year.  These provisions may require an Underlying Fund to
recognize income or gains without a concurrent receipt of cash.  Any gain or
loss recognized on actual or deemed sales of these futures contracts, forward
contracts, or options will (except for certain foreign currency options, forward
contracts, and futures contracts) be treated as 60% long-term capital gain or
loss and 40% short-term capital gain or loss.  As a result of certain hedging
transactions entered into by an Underlying Fund, the Fund may be required to
defer the recognition of losses on futures contracts, forward contracts, and
options or underlying securities or foreign currencies to the extent of any
unrecognized gains on related positions held by such Underlying Fund and the
characterization of gains or losses as long-term or short-term may be changed.
The tax provisions described above applicable to options, futures and forward
contracts may affect the amount, timing and character of an Underlying Fund's
distributions to shareholders.  Application of certain requirements for
qualification as a regulated investment company and/or these tax rules to
certain investment practices, such as dollar rolls, or certain derivatives such
as interest rate swaps, floors, caps and collars and currency, mortgage or index
swaps may be unclear in some respects, and an Underlying Fund may therefore be
required to limit its participation in such transactions. Certain tax elections
may be available to an Underlying Fund to mitigate some of the unfavorable
consequences described in this paragraph.

          Section 988 of the Code contains special tax rules applicable to
certain foreign currency transactions and instruments that may affect the
amount, timing and character of income, gain or loss recognized by an Underlying
Fund.  Under these rules, foreign exchange gain or loss realized with respect to
foreign currencies and certain futures and options thereon, foreign currency-
denominated debt instruments, foreign currency forward contracts, and foreign
currency-denominated payables and receivables will generally be treated as
ordinary income or loss, although in some cases elections may be available that
would alter this treatment. If a net foreign exchange loss treated as ordinary
loss under Section 988 of the Code were to exceed an Underlying Fund's
investment company taxable income (computed without regard to such loss) for a
taxable year, the resulting loss would not be deductible by the Fund or its
shareholders in future years. Net loss, if any, from certain of the foregoing
currency transactions or instruments could exceed net investment income
otherwise calculated for accounting purposes with the result being either no
dividends being paid or a portion of an Underlying Fund's dividends being
treated as a return of capital for tax

                                     B-103
<PAGE>
 
purposes, nontaxable to the extent of a shareholder's tax basis in his shares
and, once such basis is exhausted, generally giving rise to capital gains.

          An Underlying Fund's investment in zero coupon securities, deferred
interest securities, certain structured securities or other securities bearing
original issue discount or, if an Underlying Fund elects to include market
discount in income currently, market discount, as well as any "mark to market"
gain from certain options, futures or forward contracts, as described above,
will generally cause it to realize income or gain prior to the receipt of cash
payments with respect to these securities or contracts.  In order to obtain cash
to enable it to distribute this income or gain, maintain its qualification as a
regulated investment company and avoid federal income or excise taxes, the
Underlying Fund may be required to liquidate portfolio securities that it might
otherwise have continued to hold.

          Each Underlying Fund also intends to qualify annually and elect to be
treated as a regulated investment company under Subchapter M of the Code.  In
any year in which an Underlying Fund so qualifies and timely distributes all of
its taxable income, the Underlying Fund generally will not pay any federal
income or excise tax.  If, as may occur for certain of the Underlying Funds,
more than 50% of an Underlying Fund's total assets at the close of any taxable
year consists of stock or securities of foreign corporations, the Underlying
Fund may file an election with the Internal Revenue Service pursuant to which
shareholders of the Underlying Fund would be required to (i) include in ordinary
gross income (in addition to taxable dividends actually received) their pro rata
shares of foreign income taxes paid by the Underlying Fund that are treated as
income taxes under U.S. tax regulations (which excludes, for example, stamp
taxes, securities transaction taxes, and similar taxes) even though not actually
received by such shareholders, and (ii) treat such respective pro rata portions
as foreign income taxes paid by them.

          If an Underlying Fund makes this election, its shareholders may then
deduct such pro rata portions of qualified foreign taxes in computing their
taxable incomes, or, alternatively, use them as foreign tax credits, subject to
applicable limitations, against their U.S. federal income taxes.  Shareholders
who do not itemize deductions for federal income tax purposes will not, however,
be able to deduct their pro rata portion of foreign taxes paid by an Underlying
Fund, although such shareholders will be required to include their shares of
such taxes in gross income if the election is made.

          While a Portfolio will be able to deduct the foreign taxes that it
will be treated as receiving from an Underlying Fund if the election is made,
the Portfolio will not itself be able to elect to treat its foreign taxes as
paid by its shareholders.  Accordingly, the shareholders of the Portfolio will
not have an option of claiming a foreign tax credit for foreign taxes paid by
the Underlying Funds, while persons who invest directly in such Underlying Funds
may have that option.

          If an Underlying Fund acquires stock (including, under proposed
regulations, an option to acquire stock such as is inherent in a convertible
bond) in certain foreign corporations that receive at least 75% of their annual
gross income from passive sources (such as interest, dividends, rents, royalties
or capital gain) or hold at least 50% of their assets in investments producing
such passive income ("passive foreign investment companies"), the Underlying
Fund could be subject to federal income tax and additional interest charges on
"excess distributions" received from such companies or gain from the sale of
stock in such 


                                     B-104
<PAGE>
 
companies, even if all income or gain actually received by the Underlying Fund
is timely distributed to its shareholders. The Underlying Fund would not be able
to pass through to its shareholders any credit or deduction for such a tax. In
some cases, elections may be available that would ameliorate these adverse tax
consequences, but such elections would require the Underlying Fund to include
certain amounts as income or gain (subject to the distribution requirements
described above) without a concurrent receipt of cash. Each Fund may limit
and/or manage its holdings in passive foreign investment companies to minimize
its tax liability or maximize its return from these investments.

          Investments in lower-rated securities may present special tax issues
for an Underlying Fund to the extent actual or anticipated defaults may be more
likely with respect to such securities.  Tax rules are not entirely clear about
issues such as when an Underlying Fund may cease to accrue interest, original
issue discount, or market discount; when and to what extent deductions may be
taken for bad debts or worthless securities; how payments received on
obligations in default should be allocated between principal and income; and
whether exchanges of debt obligations in a workout context are taxable. These
and other issues will be addressed by an Underlying Fund, in the event it
invests in such securities, in order to seek to eliminate or minimize any
adverse tax consequences.

Taxable U.S. Shareholders - Distributions

          For U.S. federal income tax purposes, distributions by a Portfolio
generally will be taxable to shareholders who are subject to tax. Shareholders
receiving a distribution in the form of newly issued shares will be treated for
U.S. federal income tax purposes as receiving a distribution in an amount equal
to the amount of cash they would have received had they elected to receive cash
and will have a cost basis in each share received equal to such amount divided
by the number of shares received.

          Distributions from investment company taxable income for the year will
be taxable as ordinary income.  Distributions designated as derived from a
Portfolio's dividend income, if any, that would be eligible for the dividends
received deduction if such Portfolio's were not a regulated investment company
may be eligible for the dividends-received deduction for corporate shareholders.
The dividends-received deduction, if available, is reduced to the extent the
shares with respect to which the dividends are received are treated as debt-
financed under federal income tax law and is eliminated if the shares are deemed
to have been held for less than a minimum period, generally 46 days.  The entire
dividend, including the deducted amount, is considered in determining the
excess, if any, of a corporate shareholder's adjusted current earnings over its
alternative minimum taxable income, which may increase its liability for the
federal alternative minimum tax, and the dividend may, if it is treated as an
"extraordinary dividend" under the Code, reduce such shareholder's tax basis in
its shares of a Portfolio.  Capital gain dividends (i.e., dividends from net
capital gain), if designated as such in a written notice to shareholders mailed
not later than 60 days after a Portfolio's taxable year closes, will be taxed to
shareholders as long-term capital gain regardless of how long shares have been
held by shareholders, but are not eligible for the dividends-received deduction
for corporations. Such long-term capital gain will generally be 20% rate gain.
Distributions, if any, that are in excess of a Portfolio's current and
accumulated earnings and profits will first reduce a shareholder's tax basis in
his shares and, after such basis is reduced to zero, will generally constitute
capital gains to a shareholder who holds his shares as capital assets.


                                     B-105
<PAGE>
 
          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.  Assuming the shareholder holds the shares as a
capital asset at the time of such sale, such gain or loss should be capital in
character, and long-term if the shareholder has a tax holding period for the
shares of more than one year, otherwise short-term.  In general, the maximum
long-term capital gain rate will be 20% for gains on assets held more than one
year.  Shareholders should consult their own tax advisers with reference to
their particular circumstances to determine whether a redemption (including an
exchange) or other disposition of Portfolio shares is properly treated as a sale
for tax purposes, as is assumed in this discussion.  If a shareholder receives a
capital gain dividend with respect to shares and such shares have a tax holding
period of six months or less at the time of a sale or redemption of such shares,
then any loss the shareholder realizes on the sale or redemption will be treated
as a long-term capital loss to the extent of such capital gain dividend.  All or
a portion of any sales load paid upon the purchase of shares of a Portfolio will
not be taken into account in determining gain or loss on the redemption or
exchange of such shares within 90 days after their purchase to the extent the
redemption proceeds are reinvested, or the exchange is effected, without payment
of an additional sales load pursuant to the reinvestment or exchange privilege.
The load not taken into account will be added to the tax basis of the newly-
acquired shares.  Additionally, any loss realized on a sale or redemption of
shares of a Portfolio may be disallowed under "wash sale" rules to the extent
the shares disposed of are replaced with other shares of the same Portfolio
within a period of 61 days beginning 30 days before and ending 30 days after the
shares are disposed of, such as pursuant to a dividend reinvestment in shares of
such Portfolio.  If disallowed, the loss will be reflected in an adjustment to
the basis of the shares acquired.
    
          Each Portfolio may be required to withhold, as "backup withholding,"
federal income tax at a rate of 31% from dividends (including capital gain
dividends) and share redemption and exchange proceeds to individuals and other
non-exempt shareholders who fail to furnish such Portfolio with a correct
taxpayer identification number ("TIN") certified under penalties of perjury, or
if the Internal Revenue Service or a broker notifies the Portfolio that the
payee is subject to backup withholding as a result of failing to properly report
interest or dividend income to the Internal Revenue Service or that the TIN
furnished by the payee to the Portfolio is incorrect, or if (when required to do
so) the payee fails to certify under penalties of perjury that it is not subject
to backup withholding.  A Portfolio may refuse to accept an application that
does not contain any required TIN or certification that the TIN provided is
correct. If the backup withholding provisions are applicable, any such dividends
and proceeds, whether paid in cash or reinvested in additional shares, will be
reduced by the amounts required to be withheld. Any amounts withheld may be
credited against a shareholder's U.S. federal income tax liability.  Investors
should consult their tax advisers      


                                     B-106
<PAGE>

     
about the applicability of the banking withholding provisions. If you do not
have a TIN, you should apply for one immediately by contacting your local office
of the Social Security Administration or the Internal Revenue Services. Backup
withholding could apply to payments relating to your account while you are
waiting receipt of a TIN. Special rules apply for certain entities. For example,
for an account established under a Uniform Gifts for Transfer to Minors Act, the
TIN of the minor should be furnished.     

Non-U.S. Shareholders

          The discussion above relates solely to U.S. federal income tax law as
it applies to "U.S. persons" subject to tax under such law. Shareholders who, as
to the United States, are not "U.S. persons" (i.e., are nonresident aliens,
foreign corporations, fiduciaries of foreign trusts or estates, foreign
partnerships or other non-U.S. investors) generally will be subject to U.S.
federal withholding tax at the rate of 30% on distributions treated as ordinary
income unless the tax is reduced or eliminated pursuant to a tax treaty or the
dividends are effectively connected with a U.S. trade or business of the
shareholder.  In the latter case the dividends will be subject to tax on a net
income basis at the graduated rates applicable to U.S. individuals or domestic
corporations.  Distributions of net capital gain, including amounts retained by
a Portfolio which are designated as undistributed capital gains, to a non-U.S.
shareholder will not be subject to U.S. federal income or withholding tax unless
the distributions are effectively connected with the shareholder's trade or
business in the United States or, in the case of a shareholder who is a
nonresident alien individual, the shareholder is present in the United States
for 183 days or more during the taxable year and certain other conditions are
met.

          Any capital gain realized by a non-U.S. shareholder upon a sale or
redemption of shares of a Portfolio will not be subject to U.S. federal income
or withholding tax unless the gain is effectively connected with the
shareholder's trade or business in the U.S., or in the case of a shareholder who
is a nonresident alien individual, the shareholder is present in the U.S. for
183 days or more during the taxable year and certain other conditions are met.

          Non-U.S. persons who fail to furnish a Portfolio with an IRS Form W-8
or an acceptable substitute may be subject to backup withholding at the rate of
31% on capital gain dividends and the proceeds of redemptions and exchanges.
Each shareholder who is not a U.S. person should consult his or her tax adviser
regarding the U.S. and non-U.S. tax consequences of ownership of shares of and
receipt of distributions from the Portfolios.

State and Local

          Each Portfolio may be subject to state or local taxes in jurisdictions
in which such Portfolio may be deemed to be doing business.  In addition, in
those states or localities which have  income tax laws, the treatment of such
Portfolio and its shareholders under such laws may differ from their treatment
under federal income tax laws, and investment in such Portfolio may have tax
consequences for shareholders different from those of a direct investment in the
securities held by the Portfolio.  Shareholders should consult their own tax
advisers concerning these matters.

                              FINANCIAL STATEMENTS      
 
    
          The audited financial statements and related reports of Arthur
Andersen LLP, independent public accountants, for each Portfolio contained in
each Portfolio's 1998 Annual Report  (except Conservative Strategy Portfolio)
are hereby incorporated by reference and attached hereto.  A copy of the annual
reports may be obtained without charge by writing Goldman, Sachs & Co., 4900
Sears Tower, Chicago, Illinois 60606 or by calling Goldman, Sachs & Co., at the
telephone number on the back cover of each Portfolio's prospectus.  No other
portions of the Portfolios' Annual Reports are incorporated hereby by 
reference.     


                               OTHER INFORMATION

    
     

          Each Portfolio will redeem shares solely in cash up to the lesser of
$250,000 or 1% of the net asset value of the Portfolio during any 90-day period
for any one shareholder.  Each Portfolio, however, reserves the right to pay
redemptions exceeding $250,000 or 1% of the net asset value of the Portfolio at
the time of redemption by a distribution in kind of securities (instead of cash)
from such Portfolio.  The securities distributed in kind would be readily
marketable and would be valued for this purpose using the same method employed
in calculating the Portfolio's net asset value per share.  See "Net Asset
Value."  If a shareholder receives redemption proceeds in kind, the shareholder
should expect to incur transaction costs upon the disposition of the securities
received in the redemption.

          The right of a shareholder to redeem shares and the date of payment by
each Portfolio may be suspended for more than seven days for any period during
which the New York Stock Exchange is closed, other than the customary weekends
or holidays, or when trading on such Exchange is restricted as determined by the
SEC; or during any emergency, as determined by the SEC, as a result of which it
is not reasonably practicable for such Portfolio to dispose of securities owned
by it or fairly to determine the value of its net assets; or for such other
period as the SEC may by order permit for the protection of shareholders of such
Portfolio.  (The Trust may also suspend or postpone the recordation of the
transfer of shares upon the occurrence of any of the foregoing conditions.)

          The Prospectus and this Additional Statement do not contain all the
information included in the Registration Statement filed with the SEC under the
1933 Act with respect to the securities offered by the Prospectus.  Certain
portions of the Registration Statement have been omitted from the Prospectus and
this Additional Statement pursuant to the rules and regulations of the SEC.  The
Registration Statement including the exhibits filed  therewith may be examined
at the office of the SEC in Washington, D.C.

          Statements contained in the Prospectus or in this Additional Statement
as to the contents of any contract or other document referred to are not
necessarily complete, and, in each instance, reference is made to the copy of
such contract or other document filed as an exhibit to the Registration
Statement of which the Prospectus and this Additional Statement form a part,
each such statement being qualified in all respects by such reference.

          As stated in the Prospectuses, the Trust may authorize Service
Organizations and other institutions that provide recordkeeping, reporting and
processing services to their 


                                     B-108
<PAGE>
 
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 and Service
Plan or Service Plan described in the Prospectuses and the following sections.
Certain Service Organizations or institutions may enter into sub-transfer agency
agreements with the Trust or Goldman Sachs with respect to their services.
    
          The Adviser, Distributor and/or their affiliates may pay, out of their
own assets, compensation to Authorized Dealers, Service Organizations and other
financial intermediaries ("Intermediaries") for the sale and distribution of
shares of the Portfolios and/or for the servicing of those shares.  These
payments ("Additional Payments") would be in addition to the payments by the
Portfolios described in the Portfolios' Prospectus and this Additional Statement
for distribution and shareholder servicing and processing, and would also be in
addition to the sales commissions payable to Intermediaries as set forth in the
Prospectus.  These Additional Payments may take the form of "due diligence"
payments for an Intermediary's examination of the Portfolios and payments for
providing extra employee training and information relating to the Portfolios;
"listing" fees for the placement of the Portfolios on an Intermediary's list of
mutual funds available for purchase by its customers; "finders" or "referral"
fees for directing investors to the Portfolios; "marketing support" fees for
providing assistance in promoting the sale of the Portfolios' shares; and
payments for the sale of Shares and/or the maintenance of share balances.  In
addition, the Adviser, Distributor and/or their affiliates may make Additional
Payments for subaccounting, administrative and/or shareholder processing
services that are in addition to the shareholder servicing and processing fees
paid by the Portfolios.  The Additional Payments made by the Adviser,
Distributor and their affiliates may be a fixed dollar amount, may be based on
the number of customer accounts maintained by an Intermediary, or may be based
on a percentage of the value of shares sold to, or held by, customers of the
Intermediary involved, and may be different for different Intermediaries.
Furthermore, the Adviser, Distributor and/or their affiliates may contribute to
various non-cash and cash incentive arrangements to promote the sale of shares,
as well as sponsor various educational programs, sales contests and/or
promotions.  The Adviser, Distributor and their affiliates may also pay for the
travel expenses, meals, lodging and entertainment of Intermediaries and their
salespersons and guests in connection with educational, sales and promotional
programs subject to applicable NASD regulations.  The Distributor currently
expects that such additional bonuses or incentives will not exceed 0.50% of the
amount of any sales.

Maximum Sales Charges      
=====================
    
          Class A Shares of each Portfolio are sold at a maximum sales charge of
5.5%. Using the offering price per share, as of December 31, 1998 and $10.00 for
the Conservative Strategy Portfolio, the maximum offering price of each
Portfolio's Class A shares would be as follows:

</TABLE>      
    
Other Purchase Information     
==========================
    
The sales load waivers on the Portfolios' shares are due to the nature of the
investors involved and/or the reduced sales effort that is needed to obtain such
investments.     

          If shares of a Portfolio are held in a "street name" account with an
Authorized Dealer, all recordkeeping, transaction processing and payments of
distributions relating to the beneficial owner's account will be performed by
the Authorized Dealer, and not by a Portfolio and its Transfer Agent. Since the
Portfolios will have no record of the beneficial owner's transactions, a
beneficial owner should contact the Authorized Dealer to purchase, redeem or
exchange shares, to make changes in or give instructions concerning the account
or to obtain information about the account. The transfer of shares in a "street
name" account to an account with another dealer or to an account directly with a
Portfolio involves special procedures and will require the beneficial owner to
obtain historical purchase information about the shares in the account from the
Authorized Dealer.
    
          Authorized Dealers and other financial intermediaries provide varying
arrangements for their clients to purchase and redeem Portfolio shares. Some may
establish higher minimum investment requirements and others may limit the
availability of certain privileges with respect to the purchase and redemption
of shares or the reinvestment of dividends. Firms may arrange with their clients
for other investment or administrative services and may independently establish
and charge additional amounts to their clients for such services, which charges
would reduce a client's return.

Right of Accumulation - (Class A)     
=================================
    
          A Class A shareholder qualifies for cumulative quantity discounts if
the current purchase price of the new investment plus the shareholder's current
holdings of existing Class A Shares (acquired by purchase or exchange) of the
Portfolios and Class A Shares of any other Goldman Sachs Fund (as defined in the
Prospectus) total the requisite amount for receiving a discount. For example, if
a shareholder owns shares with a current market value of $65,000 and purchases
additional Class A Shares of the Balanced Strategy Portfolio with a purchase
price of $45,000, the sales charge for the $45,000 purchase would be 3.0% (the
rate applicable to a single purchase of more than $100,000). Class A Shares
purchased without the imposition of a sales charge and shares of another class
of the Portfolios may not be aggregated with Class A Shares purchased subject to
a sales charge. Class A Shares of the Portfolios and any other Goldman Sachs
Fund purchased (i) by an individual, his spouse and his children, and (ii) by a
trustee, guardian or other fiduciary of a single trust estate or a single
fiduciary account, will be combined for the purpose of determining whether a
purchase will qualify for such right of accumulation and, if qualifying, the
applicable sales charge level. For purposes of applying the right of
accumulation, shares of the Portfolios and any other Goldman Sachs Fund
purchased by an existing client of the Private Client Services Division of
Goldman Sachs will be combined with Class A Shares held by any other Private
Client Services account. In addition, Class A Shares of the Portfolios and Class
A Shares of any other Goldman Sachs Fund purchased by partners, directors,
officers or employees of the same business organization or by groups of
individuals represented by and investing on the recommendation of the same
accounting firm, certain affinity groups or other similar organizations
(collectively, "eligible persons") may be combined for the purpose of
determining whether a purchase will qualify for the right of accumulation and,
if qualifying, the applicable sales charge level. This right of accumulation is
subject to the following conditions: (i) the business organization's, group's or
firm's agreement to cooperate in the offering of the Portfolios' shares to
eligible persons; and (ii) notification to the Portfolios at the time of
purchase that the investor is eligible for this right of accumulation.     
    
Statement of Intention - (Class A)     
==================================
    
          If a shareholder anticipates purchasing at least $100,000 of Class A
Shares of a Portfolio alone or in combination with Class A Shares of any other
Goldman Sachs Fund within a 13-month period, the shareholder may purchase shares
of the Portfolio at a reduced sales charge by submitting a Statement of
Intention (the "Statement"). Shares purchased pursuant to a Statement will be
eligible for the same sales charge discount that would have been available if
all of the purchases had been made at the same time. The shareholder or his or
her Authorized Dealer must inform Goldman Sachs that the Statement is in effect
each time shares are purchased. There is no obligation to purchase the full
amount of shares indicated in the Statement. A shareholder may include the value
of all Class A Shares on which a sales charge has previously been paid as an
"accumulation credit" toward the completion of the Statement, but a price
readjustment will be made only on Class A Shares purchased within ninety (90)
days before submitting the Statement. The Statement authorizes the Transfer
Agent to hold in escrow a sufficient number of shares which can be redeemed to
make up any difference in the sales charge on the amount actually invested. For
purposes of satisfying the amount specified on the Statement, the gross amount
of each investment, exclusive of any appreciation on shares previously
purchased, will be taken into account.

Cross-Reinvestment of Dividends and Distributions     
=================================================
    
          You may receive dividends and distributions in additional shares of
the same class of the Portfolio in which you have invested or you may elect to
receive them in cash or shares of the same class of other mutual funds sponsored
by Goldman Sachs (the "Goldman Sachs Funds") or ILA Service Units of the Prime
Obligations Portfolio or the Tax-Exempt Diversified Portfolio, if you hold Class
A Shares of a Portfolio, or ILA Class B or Class C Units of the Prime
Obligations Portfolio, if you hold Class B or Class C Shares of a Portfolio (the
"ILA Portfolios").     

          A Portfolio shareholder should obtain and read the prospectus relating
to any other Goldman Sachs Fund or ILA Portfolio (as defined in the Prospectus)
and its shares or units and consider its investment objective, policies and
applicable fees before electing cross-reinvestment into that Fund or Portfolio.
The election to cross-reinvest dividends and capital gain distributions will not
affect the tax treatment of such dividends and distributions, which will be
treated as received by the shareholder and then used to purchase shares of the
acquired fund. Such reinvestment of dividends and distributions in shares of
other Goldman Sachs Funds or in units of ILA Portfolios is available only in
states where such reinvestment may legally be made.
    
Automatic Exchange Program     
==========================
    
          A Portfolio shareholder may elect to exchange automatically a
specified dollar amount of shares of a Portfolio into an identical account or an
account registered in a different name or with a different address, social
security or other taxpayer identification number, provided that the account in
the acquired fund has been established, appropriate signatures have been
obtained and the minimum initial investment requirement has been satisfied. A
Portfolio shareholder should obtain and read the prospectus relating to any
other Goldman Sachs Fund and its shares and consider its investment objective,
policies and applicable fees and expenses before electing an automatic exchange
into that Goldman Sachs Fund.     
    
Systematic Withdrawal Plan     
==========================

          A systematic withdrawal plan (the "Systematic Withdrawal Plan") is
available to shareholders of a Portfolio whose shares are worth at least $5,000.
The Systematic Withdrawal Plan provides for monthly payments to the
participating shareholder of any amount not less than $50.
    
          Dividends and capital gain distributions on shares held under the
Systematic Withdrawal Plan are reinvested in additional full and fractional
shares of the applicable Portfolio at net asset value. The Transfer Agent acts
as agent for the shareholder in redeeming sufficient full and fractional shares
to provide the amount of the systematic withdrawal payment.  The Systematic
Withdrawal Plan may be terminated at any time.  Goldman Sachs reserves the right
to initiate a fee of up to $5 per withdrawal, upon thirty (30) days written
notice to the shareholder.  Withdrawal payments should not be considered to be
dividends, yield or income.  If periodic withdrawals continuously exceed new
purchases and reinvested dividends and capital gains distributions, the
shareholder's original investment will      


                                     B-112
<PAGE>

     
be correspondingly reduced and ultimately exhausted. The maintenance of a
withdrawal plan concurrently with purchases of additional Class A, Class B or
Class C Shares would be disadvantageous because of the sales charge imposed on
purchases of Class A Shares or the imposition of a CDSC on redemptions of Class
A, Class B and Class C Shares. The CDSC applicable to Class B and Class C Shares
redeemed under a systematic withdrawal plan may be waived. See "Shareholder
Guide" in the Prospectus. In addition, each withdrawal constitutes a redemption
of shares, and any gain or loss realized must be reported for federal and state
income tax purposes. A shareholder should consult his or her own tax adviser
with regard to the tax consequences of participating in the Systematic
Withdrawal Plan. For further information or to request a Systematic Withdrawal
Plan, please write or call the Transfer Agent.     

                         DISTRIBUTION AND SERVICE PLANS
                   (Class A, Class B and Class C Shares Only)
                                            
          As described in the Prospectus, the Trust has adopted, on behalf of
Class A, Class B and Class C Shares of each Portfolio, distribution and service
plans (each a "Plan") pursuant to Rule 12b-1 under the Act.     
    
          The Plans for each Portfolio were most recently approved on [April __,
1999] by a majority vote of the Trustees of the Trust, including a majority of
the non-interested Trustees of the Trust who have no direct or indirect
financial interest in the Plans, cast in person at a meeting called for the
purpose of approving the Plans.     
    
          The compensation for distribution services payable under a Plan may
not exceed 0.25%, 0.75% and 0.75% per annum of a Portfolio's average daily net
assets attributable to Class A, Class B and Class C Shares, respectively, of
such Portfolio. Under the Plans for Class B and Class C Shares, Goldman Sachs is
also entitled to receive a separate fee for personal and account maintenance
services equal to an annual basis of 0.25% of each Portfolio's average daily net
assets attributable to Class B or Class C Shares. With respect to Class A
Shares, the Distributor at its discretion may use compensation for distribution
services paid under the Plan for personal and account maintenance services and
expenses so long as such total compensation under the Plan does not exceed the
maximum cap on "service fees" imposed by the NASD.     
    
          Each Plan is a compensation plan which provides for the payment of a
specified fee without regard to the expenses actually incurred by Goldman Sachs.
If such fee exceeds Goldman Sachs' expenses, Goldman Sachs may realize a profit
from these arrangements. The distribution fees received by Goldman Sachs under
the Plans and contingent deferred sales charge on Class A, Class B and Class C
Shares may be sold by Goldman Sachs as distributor to entities which provide
financing for payments to Authorized Dealers in respect of sales of Class A,
Class B and Class C Shares. To the extent such fees are not paid to such
dealers, Goldman Sachs may retain such fee as compensation for its services and
expenses of distributing the Portfolios' Class A, Class B and Class C 
Shares.     

          Under each Plan, Goldman Sachs, as distributor of each Portfolio's
Class A, Class B and Class C Shares, will provide to the Trustees of the Trust
for their review, and the Trustees of the Trust will review at least quarterly a
written report of the services provided


                                     B-113
<PAGE>
 
and amounts expended by Goldman Sachs under the Plans and the purposes for which
such services were performed and expenditures were made.
    
          The Plans will remain in effect until [May 1, 2000] and from year to
year thereafter, provided that such continuance is approved annually by a
majority vote of the Trustees of the Trust, including a majority of the non-
interested Trustees of the Trust who have no direct or indirect financial
interest in the Plans. The Plans may not be amended to increase materially the
amount of distribution compensation described therein without approval of a
majority of the outstanding Class A, Class B or Class C Shares of the affected
Portfolio and share class. All material amendments of a Plan must also be
approved by the Trustees of the Trust in the manner described above. A Plan may
be terminated at any time as to any Portfolio without payment of any penalty by
a vote of a majority of the non-interested Trustees of the Trust or by vote of a
majority of the outstanding Class A, Class B or Class C Shares, respectively, of
the applicable Portfolio and share class. If a Plan was terminated by the
Trustees of the Trust and no successor plan was adopted, the Portfolio would
cease to make payments to Goldman Sachs under the Plan and Goldman Sachs would
be unable to recover the amount of any of its unreimbursed expenditures. So long
as a Plan is in effect, the selection and nomination of non-interested Trustees
of the Trust will be committed to the discretion of the non-interested Trustees
of the Trust. The Trustees of the Trust have determined that in their judgment
there is a reasonable likelihood that the Plans will benefit the Portfolios and
their Class A, Class B and Class C Shareholders.     
    
          For the period ended December 31, 1998, the distribution fees paid to
Goldman Sachs by each Portfolio then in existence pursuant to the Class A, Class
B and Class C Plans were as follows:

                             (Service Shares Only)

     Each Portfolio has adopted a service plan (the "Plan") with respect to its
Service Shares which authorizes it to compensate Service Organizations for
providing certain administration services and personal and account maintenance
services to their customers who are or may become beneficial owners of such
Shares.  Pursuant to the Plan, a Portfolio will enter into agreements with
Service Organizations which purchase Service Shares of the Portfolio on behalf
of their customers ("Service Agreements").  Under such Service Agreements the
Service Organizations may perform some or all of the following services:  (a)
act, directly or through an agent, as the sole shareholder of record and nominee
for all customers, (b) maintain account records for each customer who
beneficially owns Service Shares of a Portfolio, (c) answer questions and handle
correspondence from customers regarding their accounts, (d) process customer
orders to purchase, redeem and exchange Service Shares of a Portfolio, and
handle the transmission of funds representing the customers' purchase price or
redemption proceeds, (e) issue confirmations for transactions in shares by
customers, (f) provide facilities to answer questions from prospective and
existing investors about Service Shares of a Portfolio, (g) receive and answer
investor correspondence, including requests for prospectuses and statements of
additional information, (h) display and make prospectuses available on the
Service Organization's premises, (i) assist customers in completing application
forms, selecting dividend and other account options and opening custody accounts
with the Service Organization and (j) act as liaison between customers and a
Portfolio, including obtaining information from a Portfolio, working with a
Portfolio to correct errors and resolve problems and providing statistical and
other information to a Portfolio.  As compensation for such services, a
Portfolio will pay each Service Organization a service fee in an amount up to
0.50% (on an annualized basis) of the average daily net assets of the Service
Shares of such Portfolio attributable to or held in the 

                                     B-118

name of such Service Organization; provided, however, that the fee paid for
personal and account maintenance services shall not exceed 0.25% such average
daily net assets.

Service Organizations was as follows for the period ended December 31:

2    The Balanced Strategy, Growth and Income Strategy, Growth Strategy and
     Aggressive Growth Strategy Portfolios commenced operations on January 2,
     1998.

     Each Portfolio has adopted its Plan pursuant to Rule 12b-1 under the 1940
Act in order to avoid any possibility that payments to the Service Organizations
pursuant to the Service Agreements might violate the 1940 Act.  Rule 12b-1,
which was adopted by the SEC under the Act, regulates the circumstances under
which an investment  company or series thereof may bear expenses associated with
the distribution of its shares.  In particular, such an investment company or
series thereof cannot engage directly or indirectly in financing any activity
which is primarily intended to result in the sale of shares issued by the
company unless it has adopted a plan pursuant to, and complies with the other
requirements of, such Rule.  The Trust believes that fees paid for the services
provided in the Plan and described above are not expenses incurred primarily for
effecting the distribution of Service Shares.  However, should such payments be
deemed by a court or the SEC to be distribution expenses, such payments would be
duly authorized by the Plan.
    
     The Glass-Steagall Act prohibits all entities which receive deposits from
engaging to any extent in the business of issuing, underwriting, selling or
distributing securities, although institutions such as national banks are
permitted to purchase and sell securities upon the order and for the account of
their customers.  In addition, under some state securities laws, banks and other
financial institutions purchasing Service Shares on behalf of their customers
may be required to register as dealers.  Should future legislative or
administrative action or judicial or administrative decisions or interpretations
prohibit or restrict the activities of one or more of the Service Organizations
in connection with the Portfolios, such Service Organizations might be required
to alter materially or discontinue the services performed under their Service
Agreements.  If one or more of the Service Organizations were restricted from
effecting purchases or sales of Service Shares automatically pursuant to pre-
authorized instructions, for example, effecting such transactions on a manual
basis might affect the size and/or growth of a Portfolio.  Any such alteration
or discontinuance of services could require the Board of Trustees to consider
changing a Portfolio's method of operations or providing alternative means of
offering Service Shares of a Portfolio to customers of such Service
Organizations, in which case the operation of such Portfolio, its size and/or
its growth might be significantly altered.  It is not anticipated, however, that
any alteration of a Portfolio's      

                                     B-119
<PAGE>
 
operations would have any effect on the net asset value per share or result in
financial losses to any shareholder.
    
     Conflict of interest restrictions (including the Employee Retirement Income
Security Act of 1974) may apply to a Service Organization's receipt of
compensation paid by a Portfolio in connection with the investment of fiduciary
assets in Service Shares of such Portfolio.  Service Organizations, including
banks regulated by the Comptroller of the Currency, the Federal Reserve Board or
the Federal Deposit Insurance Corporation, and investment  advisers and other
money managers subject to the jurisdiction of the SEC, the Department of Labor
or state securities regulators, are urged to consult their legal advisers before
investing fiduciary assets in Service Shares of the Portfolios.  In addition,
under some state securities laws, banks and other financial institutions
purchasing Service Shares on behalf of their customers may be required to
register as dealers.     
    
     The Trustees, including a majority of the Trustees who are not interested
persons of the Trust and who have no direct or indirect financial interest in
the operation of the Plan or the related Service Agreements, most recently voted
to approve each Portfolio's Plan and related Service Agreements at a meeting
called for the purpose of voting on such Plan and Service Agreements on
________, 1999.  The Plan and Service Agreements will remain in effect until
___________, 2000 and will continue in effect thereafter only if such
continuance is specifically approved annually by a vote of the Board of Trustees
in the manner described above.  The Plan may not be amended to increase
materially the amount to be spent for the services described therein without
approval of the Service Shareholders of the affected Portfolio, and all material
amendments of the Plan must also be approved by the Board of Trustees in the
manner described above.  The Plan may be terminated at any time by a majority of
the Board of Trustees as described above or by vote of a majority of the
outstanding Service Shares of the affected Portfolio.  The Service Agreements
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Board of Trustees as described above or by a vote of a majority
of the outstanding Service Shares of the affected Portfolio on not more than
sixty (60) days' written notice to any other party to the Service Agreements.
The Service Agreements will terminate automatically if assigned.  So long as the
Plan is in effect, the selection and nomination of those Trustees who are not
interested persons will be committed to the discretion of the Trust's Nominating
Committee, which consists of all of the non-interested members of the Board of
Trustees.  The Board of Trustees has determined that, in its judgment, there is
a reasonable likelihood that a Portfolio's Plan will benefit such Portfolio and
its holders of Service Shares.

GOLDMAN SACHS ASSET ALLOCATION PORTFOLIOS
Notes to Financial Statements
December 31, 1998
 1. ORGANIZATION
 
 Goldman Sachs Trust (the "Trust") is a Delaware business trust registered un-
 der the Investment Company Act of 1940 (as amended) as an open-end, manage-
 ment investment company. The Trust includes Goldman Sachs Balanced Strategy
 Portfolio formerly, the Goldman Sachs Income Strategy Portfolio- (Balanced
 Strategy), Goldman Sachs Growth and Income Strategy Portfolio (Growth and In-
 come Strategy), Goldman Sachs Growth Strategy Portfolio (Growth Strategy) and
 Goldman Sachs Aggressive Growth Strategy Portfolio (Aggressive Growth Strate-
 gy), collectively, (the "Portfolios") or individually (a "Portfolio"). Effec-
 tive February 8, 1999, the name of Goldman Sachs Income Strategy Portfolio
 was changed to Goldman Sachs Balanced Strategy Portfolio. All of the Portfo-
 lios offer five classes of shares --Class A, Class B, Class C, Institutional
 and Service shares.
 
 2. SIGNIFICANT ACCOUNTING POLICIES
 
 The following is a summary of significant accounting policies consistently
 followed by the Portfolios. The preparation of financial statements in con-
 formity with generally accepted accounting principles requires management to
 make estimates and assumptions that may affect the reported amounts.
 
 A. Investment Valuation -- Each Portfolio invests in a combination of Under-
 lying Funds (the "Underlying Funds") for which Goldman Sachs Asset Management
 ("GSAM"), a separate operating division of Goldman Sachs & Co. ("Goldman
 Sachs"), Goldman Sachs Funds Management L.P. ("GSFM"), an affiliate of
 Goldman Sachs or Goldman Sachs Asset Management International ("GSAMI"), an
 affiliate of Goldman Sachs, acts as investment adviser. Investments in the
 Underlying Funds are valued at the closing net asset value per share of each
 Underlying Fund on the day of valuation. Because each Portfolio invests pri-
 marily in other mutual funds, which fluctuate in value, the Portfolios'
 shares will correspondingly fluctuate in value. Short-term debt obligations
 maturing in sixty days or less are valued at amortized cost.
 
 B. Securities Transactions and Investment Income -- Security transactions are
 recorded as of trade date. Realized gains and losses on sales of portfolio
 securities are calculated on the identified cost basis. Dividend income and
 capital gains distributions from the Underlying Funds are recorded on the ex-
 dividend date. Interest income is determined on the basis of interest ac-
 crued.
 
 C. Federal Taxes -- It is each Portfolio's policy to comply with the require-
 ments of the Internal Revenue Code applicable to regulated investment compa-
 nies and to distribute each year substantially all of its investment company
 taxable income and capital gains to its shareholders. Accordingly, no federal
 tax provisions are required.
   The characterization of distributions to shareholders for financial report-
 ing purposes is determined in accordance with income tax rules. Therefore,
 the source of a Portfolio's distributions may be shown in the accompanying
 financial statements as either from or in excess of net investment income or
 net realized gain on investment transactions, or from paid-in-capital, de-
 pending on the type of book/tax differences that may exist.
 
 D. Expenses -- Expenses incurred by the Trust that do not specifically relate
 to an individual Portfolio of the Trust are allocated to the Portfolios based
 on the nature of the expense.
   Class A, Class B and Class C shareholders of the Portfolios bear all ex-
 penses and fees relating to their respective distribution and service plans.
 Shareholders of Service shares bear all expenses and fees paid to service or-
 ganizations for their services with respect to such shares. Effective Septem-
 ber 1, 1998, each Class of shares of the Funds now separately bears its
 respective class-specific transfer agency fees.
 
 E. Deferred Organization Expenses -- Organization-related costs are being am-
 ortized on a straight line basis over a period of five years.

 3. AGREEMENTS
 
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as Portfolios' investment ad-
 viser pursuant to the Investment Management Agreement (the "Agreement"). Un-
 der the Agreement, GSAM, subject to the general supervision of the Trust's
 Board of Trustees, manages the Portfolios. As compensation for the services
 rendered pursuant to the Agreement, the assumption of the expenses related
 thereto and administering the Portfolios' business affairs, including provid-
 ing facilities, GSAM is entitled to a fee, computed daily and payable monthly
 at an annual rate equal to .35% of average daily net assets of each Portfo-
 lio.
   During the period, GSAM has voluntarily agreed to limit "Other Expenses"
 (excluding management fees, distribution and service fees, taxes, interest,
 brokerage, litigation, service share fees, indemnification costs and other
 extraordinary expenses) to the extent that such expenses exceed .10% of the
 average daily net assets of each Portfolio. Effective September 1, 1998 this
 expense limitation was modified to .00% (excluding management fees, distribu-
 tion and service fees, transfer agent fees, taxes, interest, brokerage, liti-
 gation, service share fees, indemnification costs and extraordinary expenses)
 of the average daily net assets of each Fund until further notice.
   Goldman Sachs serves as Distributor of the shares of the Portfolios pursu-
 ant to Distribution Agreements. Goldman Sachs may receive a portion of the
 Class A sales load and Class B and Class C contingent deferred sales charges
 and has advised the Portfolios that it retained approximately $156,000,
 $858,000, $593,000 and $243,000 for the period ended December 31, 1998 for
 the Balanced, Growth and Income, Growth and Aggressive Growth Strategies,
 respectively.
   The Trust, on behalf of each Portfolio, has adopted Distribution Plans (the
 "Distribution Plans") pursuant to Rule 12b-1. Under the Distribution Plans,
 Goldman Sachs was entitled to a quarterly fee from each Portfolio for distri-
 bution services equal, on an annual basis, to .25%, .75% and .75% of the av-
 erage daily net assets attributable to Class A, Class B and Class C shares,
 respectively.
   The Trust, on behalf of each Portfolio, had adopted Authorized Dealer Serv-
 ice Plans (the "Dealer Service Plans") pursuant to which Goldman Sachs and
 Authorized Dealers were compensated for providing personal and account main-
 tenance services. Each Portfolio paid a fee under the Dealer Service Plan
 equal, on an annual basis, to .25% of its average daily net assets attribut-
 able to Class A, Class B and Class C shares.
   Effective September 1, 1998, the Distribution Plans and Authorized Dealer
 Service Plans were combined into Distribution and Service Plans. Under the
 Distribution and Service Plans, Goldman Sachs and/or Authorized Dealers are
 entitled to a monthly fee from each Portfolio for distribution and service
 fees equal, on an annual basis, to .25%, 1.00% and 1.00% of the average daily
 net assets attributable to Class A, Class B and Class C shares, respectively.
   Goldman Sachs also serves as Transfer Agent of the Portfolios for a fee.
 Effective September 1, 1998 fees charged for such transfer agency services
 are calculated daily and payable monthly at an annual rate as follows: 0.19%
 of average daily net assets for Class A, Class B and Class C shares and .04%
 of average daily net assets for Institutional and Service Class shares.
   The Trust, on behalf of each Portfolio, has adopted Service Plans. These
 plans allow for Service shares to compensate service organizations for pro-
 viding varying levels of account administration and shareholder liaison serv-
 ices to their customers, who are beneficial owners of such shares. The
 Service Plan provides for compensation to the service organizations in an
 amount up to .50% (on an annualized basis), respectively, of the average
 daily net asset value of the Service shares.

 5. LINE OF CREDIT FACILITY
 
 The Portfolios participate in a $250,000,000 uncommitted, unsecured revolving
 line of credit facility and a $50,000,000 committed, unsecured revolving line
 of credit facility. Both facilities are to be used solely for temporary or
 emergency purposes. Under the most restrictive arrangement, each Portfolio
 must own securities having a market value in excess of 300% of the total bank
 borrowings. The interest rate on the borrowings is based on the federal funds
 rate. The committed facility also requires a fee to be paid by each Portfolio
 based on the amount of the commitment which has not been utilized. During the
 period ended December 31, 1998, the Portfolios did not have any borrowings
 under these facilities.

 6. REPURCHASE AGREEMENTS
 
 During the term of a repurchase agreement, the value of the underlying secu-
 rities, including accrued interest, is required to equal or exceed the value
 of the repurchase agreement. The underlying securities for all repurchase
 agreements are held in safekeeping at the Portfolios' custodian.
 
 7. JOINT REPURCHASE AGREEMENT ACCOUNT
 
 The Portfolios, together with other registered investment companies having
 management agreements with GSAM or their affiliates, transfer uninvested cash
 into joint accounts, the daily aggregate balance of which is invested in one
 or more repurchase agreements.
   At December 31, 1998, Balanced Strategy had undivided interests in the re-
 purchase agreements in the following joint account which equaled $200,000 in
 principal amount. At December 31, 1998, the following repurchase agreements
 held in this joint account were fully collateralized by Federal Agency obli-
 gations.

 8. CERTAIN RECLASSIFICATIONS
 
 In accordance with Statement of Position 93-2, the Balanced Strategy Portfo-
 lio reclassified $12,226 and $241,230 from paid-in capital and accumulated
 net realized loss, respectively, to accumulated undistributed net investment
 income. The Growth and Income Strategy Portfolio reclassified $47,837 and
 $1,660,180 from paid-in capital and accumulated net realized loss, respec-
 tively, to accumulated undistributed net investment income. The Growth Strat-
 egy Portfolio has reclassified $65,688 and $470,012 from paid-in capital and
 accumulated net realized loss, respectively, to accumulated undistributed net
 investment income. The Aggressive Growth Strategy has reclassified $14,965
 and $1,196 from paid-in capital and accumulated net realized loss, respec-
 tively, to accumulated undistributed net investment income. These reclassifi-

Commercial Paper Ratings
- ------------------------

     A Standard & Poor's ("S&P") commercial paper rating is a current assessment
of the likelihood of timely payment of debt having an original maturity of no
more than 365 days. The following summarizes the rating categories used by
Standard and Poor's for commercial paper:

     "A-1" - Obligations are rated in the highest category indicating that the
obligor's capacity to meet its financial commitment on the obligation is strong.
Within this category, certain obligations are designated with a plus sign (+).
This indicates that the obligor's capacity to meet its financial commitment on
these obligations is extremely strong.

     "A-2" - Obligations are somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than obligations in higher
rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

     "A-3" - Obligations exhibit adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.

     "B" - Obligations are regarded as having significant speculative
characteristics. The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

     "C" - Obligations are currently vulnerable to nonpayment and are dependent
upon favorable business, financial, and economic conditions for the obligor to
meet its financial commitment on the obligation.

     "D" - Obligations are in payment default. The "D" rating category is used
when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless S&P believes that such payments
will be made during such grace period. The "D" rating will be used upon the
filing of a bankruptcy petition or the taking of a similar action if payments on
an obligation are jeopardized.

     Moody's commercial paper ratings are opinions of the ability of issuers to
repay punctually senior debt obligations not having an original maturity in
excess of one year, unless explicitly noted. The following summarizes the rating
categories used by Moody's for commercial paper:

     "Prime-1" - Issuers (or supporting institutions) have a superior ability
for repayment of senior short-term debt obligations. Prime-1 repayment ability
will often be evidenced by many of the following characteristics: leading market
positions in well-established industries; high rates of return on funds
employed; conservative capitalization structure with moderate reliance on debt
and ample asset protection; broad margins in earnings coverage of fixed
financial 

                                      A-1
<PAGE>
 
charges and high internal cash generation; and well-established access to a
range of financial markets and assured sources of alternate liquidity.

     "Prime-2" - Issuers (or supporting institutions) have a strong ability for
repayment of senior short-term debt obligations. This will normally be evidenced
by many of the characteristics cited above but to a lesser degree. Earnings
trends and coverage ratios, while sound, may be more subject to variation.
Capitalization characteristics, while still appropriate, may be more affected by
external conditions. Ample alternate liquidity is maintained.

     "Prime-3" - Issuers (or supporting institutions) have an acceptable ability
for repayment of senior short-term debt obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes in the level of debt protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.

     "Not Prime" - Issuers do not fall within any of the Prime rating
categories.


     The three rating categories of Duff & Phelps for investment grade
commercial paper and short-term debt are "D-1," "D-2" and "D-3." Duff & Phelps
employs three designations, "D-1+," "D-1" and "D-1-," within the highest rating
category. The following summarizes the rating categories used by Duff & Phelps
for commercial paper:

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

     "D-1" - Debt possesses very high certainty of timely payment. Liquidity
factors are excellent and supported by good fundamental protection factors. Risk
factors are minor.

     "D-1-" - Debt possesses high certainty of timely payment. Liquidity factors
are strong and supported by good fundamental protection factors. Risk factors
are very small.

     "D-2" - Debt possesses good certainty of timely payment. Liquidity factors
and company fundamentals are sound. Although ongoing funding needs may enlarge
total financing requirements, access to capital markets is good. Risk factors
are small.

     "D-3" - Debt possesses satisfactory liquidity and other protection factors
qualify issues as to investment grade. Risk factors are larger and subject to
more variation. Nevertheless, timely payment is expected.

                                      A-2
<PAGE>
 
     "D-4" - Debt possesses speculative investment characteristics. Liquidity is
not sufficient to insure against disruption in debt service. Operating factors
and market access may be subject to a high degree of variation.

     "D-5" - Issuer has failed to meet scheduled principal and/or interest
payments.


     Fitch IBCA short-term ratings apply to debt obligations that have time
horizons of less than 12 months for most obligations, or up to three years for
U.S. public finance securities. The following summarizes the rating categories
used by Fitch IBCA for short-term obligations:

     "F1" - Securities possess the highest credit quality. This designation
indicates the strongest capacity for timely payment of financial commitments and
may have an added "+" to denote any exceptionally strong credit feature.

     "F2" - Securities possess good credit quality. This designation indicates a
satisfactory capacity for timely payment of financial commitments, but the
margin of safety is not as great as in the case of the higher ratings.

     "F3" - Securities possess fair credit quality. This designation indicates
that the capacity for timely payment of financial commitments is adequate;
however, near-term adverse changes could result in a reduction to non-investment
grade.

     "B" - Securities possess speculative credit quality. This designation
indicates minimal capacity for timely payment of financial commitments, plus
vulnerability to near-term adverse changes in financial and economic conditions.

     "C" - Securities possess high default risk. This designation indicates that
default is a real possibility and that the capacity for meeting financial
commitments is solely reliant upon a sustained, favorable business and economic
environment.

                                      A-3
<PAGE>
 
     "D" - Securities are in actual or imminent payment default.


     Thomson BankWatch short-term ratings assess the likelihood of an untimely
payment of principal and interest of debt instruments with original maturities
of one year or less. The following summarizes the ratings used by Thomson
BankWatch:

     "TBW-1" - This designation represents Thomson BankWatch's highest category
and indicates a very high likelihood that principal and interest will be paid on
a timely basis.

     "TBW-2" - This designation represents Thomson BankWatch's second-highest
category and indicates that while the degree of safety regarding timely
repayment of principal and interest is strong, the relative degree of safety is
not as high as for issues rated "TBW-1."

     "TBW-3" - This designation represents Thomson BankWatch's lowest
investment- grade category and indicates that while the obligation is more
susceptible to adverse developments (both internal and external) than those with
higher ratings, the capacity to service principal and interest in a timely
fashion is considered adequate.

     "TBW-4" - This designation represents Thomson BankWatch's lowest rating
category and indicates that the obligation is regarded as non-investment grade
and therefore speculative.


Corporate and Municipal Long-Term Debt Ratings
- ----------------------------------------------

The following summarizes the ratings used by Standard & Poor's for corporate and
municipal debt:

     "AAA" - An obligation rated "AAA" has the highest rating assigned by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is extremely strong.

     "AA" - An obligation rated "AA" differs from the highest rated obligations
only in small degree. The obligor's capacity to meet its financial commitment on
the obligation is very strong.

     "A" - An obligation rated "A" is somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher-rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

     "BBB" - An obligation rated "BBB" exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

     Obligations rated "BB," "B," "CCC," "CC" and "C" are regarded as having
significant speculative characteristics. "BB" indicates the least degree of
speculation and "C" the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.

                                      A-4
<PAGE>
 
     "BB" - An obligation rated "BB" is less vulnerable to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.

     "B" - An obligation rated "B" is more vulnerable to nonpayment than
obligations rated "BB", but the obligor currently has the capacity to meet its
financial commitment on the obligation. Adverse business, financial or economic
conditions will likely impair the obligor's capacity or willingness to meet its
financial commitment on the obligation.

     "CCC" - An obligation rated "CCC" is currently vulnerable to nonpayment,
and is dependent upon favorable business, financial and economic conditions for
the obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial, or economic conditions, the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.

     "CC" - An obligation rated "CC" is currently highly vulnerable to
nonpayment.

     "C" - The "C" rating may be used to cover a situation where a bankruptcy
petition has been filed or similar action has been taken, but payments on this
obligation are being continued.

     "D" - An obligation rated "D" is in payment default. The "D" rating
category is used when payments on an obligation are not made on the date due
even if the applicable grace period has not expired, unless S&P believes that
such payments will be made during such grace period. The "D" rating also will be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments on an obligation are jeopardized.

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

     "r" - This symbol is attached to the ratings of instruments with
significant noncredit risks. It highlights risks to principal or volatility of
expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

  The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt:

                                      A-5
<PAGE>
 
     "Aaa" - Bonds are judged to be of the best quality. They carry the smallest
degree of investment risk and are generally referred to as "gilt edged."
Interest payments are protected by a large or by an exceptionally stable margin
and principal is secure. While the various protective elements are likely to
change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.

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

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

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

     "Ba," "B," "Caa," "Ca" and "C" - Bonds that possess one of these ratings
provide questionable protection of interest and principal ("Ba" indicates
speculative elements; "B" indicates a general lack of characteristics of
desirable investment; "Caa" are of poor standing; "Ca" represents obligations
which are speculative in a high degree; and "C" represents the lowest rated
class of bonds). "Caa," "Ca" and "C" bonds may be in default.

     Con. (---) - Bonds for which the security depends upon the completion of
some act or the fulfillment of some condition are rated conditionally. These are
bonds secured by (a) earnings of projects under construction, (b) earnings of
projects unseasoned in operating experience, (c) rentals which begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches. Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.

     Note: Moody's applies numerical modifiers 1, 2, and 3 in each generic
rating classification from "Aa" through "Caa." The modifier 1 indicates that the
obligation ranks in the higher end of its generic rating category; the modifier
2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the
lower end of its generic rating category.

     The following summarizes the long-term debt ratings used by Duff & Phelps
for corporate and municipal long-term debt:

     "AAA" - Debt is considered to be of the highest credit quality. The risk
factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

     "AA" - Debt is considered to be of high credit quality. Protection factors
are strong. Risk is modest but may vary slightly from time to time because of
economic conditions.

                                      A-6
<PAGE>
 
     "A" - Debt possesses protection factors which are average but adequate.
However, risk factors are more variable in periods of greater economic stress.

     "BBB" - Debt possesses below-average protection factors but such protection
factors are still considered sufficient for prudent investment. Considerable
variability in risk is present during economic cycles.

     "BB," "B," "CCC," "DD" and "DP" - Debt that possesses one of these ratings
is considered to be below investment grade. Although below investment grade,
debt rated "BB" is deemed likely to meet obligations when due. Debt rated "B"
possesses the risk that obligations will not be met when due. Debt rated "CCC"
is well below investment grade and has considerable uncertainty as to timely
payment of principal, interest or preferred dividends. Debt rated "DD" is a
defaulted debt obligation, and the rating "DP" represents preferred stock with
dividend arrearages.

     To provide more detailed indications of credit quality, the "AA," "A,"
"BBB," "BB" and "B" ratings may be modified by the addition of a plus (+) or
minus (-) sign to show relative standing within these major categories.

     The following summarizes the ratings used by Fitch IBCA for corporate and
municipal bonds:

     "AAA" - Bonds considered to be investment grade and of the highest credit
quality. These ratings denote the lowest expectation of credit risk and are
assigned only in case of exceptionally strong capacity for timely payment of
financial commitments. This capacity is highly unlikely to be adversely affected
by foreseeable events.

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

     "A" - Bonds considered to be investment grade and of high credit quality.
These ratings denote a low expectation of credit risk and indicate strong
capacity for timely payment of financial commitments. This capacity may,
nevertheless, be more vulnerable to changes in circumstances or in economic
conditions than is the case for higher ratings.

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

     "BB" - Bonds considered to be speculative. These ratings indicate that
there is a possibility of credit risk developing, particularly as the result of
adverse economic changes over time; however, business or financial alternatives
may be available to allow financial commitments to be met. Securities rated in
this category are not investment grade.

     "B" - Bonds are considered highly speculative. These ratings indicate that
significant credit risk is present, but a limited margin of safety remains.
Financial commitments are

                                      A-7
<PAGE>
 
currently being met; however, capacity for continued payment is contingent upon
a sustained, favorable business and economic environment.

     "CCC," "CC", "C" - Bonds have high default risk. Default is a real
possibility, and capacity for meeting financial commitments is solely reliant
upon sustained, favorable business or economic developments. "CC" ratings
indicate that default of some kind appears probable, and "C" ratings signal
imminent default.

     "DDD," "DD" and "D" - Bonds are in default. Securities are not meeting
obligations and are extremely speculative. "DDD" designates the highest
potential for recovery of amounts outstanding on any securities involved and "D"
represents the lowest potential for recovery.

     To provide more detailed indications of credit quality, the Fitch IBCA
ratings from and including "AA" to "B" may be modified by the addition of a plus
(+) or minus (-) sign to show relative standing within these major rating
categories.

     Thomson BankWatch assesses the likelihood of an untimely repayment of
principal or interest over the term to maturity of long term debt and preferred
stock which are issued by United States commercial banks, thrifts and non-bank
banks; non-United States banks; and broker-dealers. The following summarizes the
rating categories used by Thomson BankWatch for long-term debt ratings:

     "AAA" - This designation indicates that the ability to repay principal and
interest on a timely basis is extremely high.

     "AA" - This designation indicates a very strong ability to repay principal
and interest on a timely basis, with limited incremental risk compared to issues
rated in the highest category.

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

     "BBB" - This designation represents the lowest investment-grade category
and indicates an acceptable capacity to repay principal and interest. Issues
rated "BBB" are more vulnerable to adverse developments (both internal and
external) than obligations with higher ratings.

     "BB," "B," "CCC" and "CC" - These designations are assigned by Thomson
BankWatch to non-investment grade long-term debt. Such issues are regarded as
having speculative characteristics regarding the likelihood of timely payment of
principal and interest. "BB" indicates the lowest degree of speculation and "CC"
the highest degree of speculation.

     "D" - This designation indicates that the long-term debt is in default.

     PLUS (+) OR MINUS (-) - The ratings from "AAA" through "CC" may include a
plus or minus sign designation which indicates where within the respective
category the issue is placed.

                                      A-8

Municipal Note Ratings
- ----------------------

     A Standard and Poor's rating reflects the liquidity concerns and market
access risks unique to notes due in three years or less. The following
summarizes the ratings used by Standard & Poor's Ratings Group for municipal
notes:

     "SP-1" - The issuers of these municipal notes exhibit a strong capacity to
pay principal and interest. Those issues determined to possess very strong
characteristics are given a plus (+) designation.

     "SP-2" - The issuers of these municipal notes exhibit satisfactory capacity
to pay principal and interest, with some vulnerability to adverse financial and
economic changes over the term of the notes.

     "SP-3" - The issuers of these municipal notes exhibit speculative capacity
to pay principal and interest.


     Moody's ratings for state and municipal notes and other short-term loans
are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade ("VMIG"). Such
ratings recognize the differences between short-term credit risk and long-term
risk. The following summarizes the ratings by Moody's Investors Service, Inc.
for short-term notes:

     "MIG-1"/"VMIG-1" - This designation denotes best quality. There is present
strong protection by established cash flows, superior liquidity support or
demonstrated broad-based access to the market for refinancing.

     "MIG-2"/"VMIG-2" - This designation denotes high quality, with margins of
protection that are ample although not so large as in the preceding group.

     "MIG-3"/"VMIG-3" - This designation denotes favorable quality, with all
security elements accounted for but lacking the undeniable strength of the
preceding grades. Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.

     "MIG-4"/"VMIG-4" - This designation denotes adequate quality. Protection
commonly regarded as required of an investment security is present and although
not distinctly or predominantly speculative, there is specific risk.

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

     Fitch IBCA and Duff & Phelps use the short-term ratings described under
Commercial Paper Ratings for municipal notes.

                   BUSINESS PRINCIPLES OF GOLDMAN, SACHS & CO.

     Goldman Sachs is noted for its Business Principles, which guide all of the
firm's activities and serve as the basis for its distinguished reputation among
investors worldwide.

     Our client's interests always come first.  Our experience shows that if we
serve our clients well, our own success will follow.

     Our assets are our people, capital and reputation.  If any of these 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 maintain the loyalty, the intimacy and the
esprit de corps that we all treasure and that contribute greatly to our success.

                                      1-B
<PAGE>
 
     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.

The Management Agreement with each of the Funds (other than the ILA Portfolios)
provides that the applicable Investment Adviser will not be liable for any error
of judgment or mistake of law or for any loss suffered by a Fund, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
the Investment Adviser or from reckless disregard by the Investment Adviser of
its obligations or duties under the Management Agreement.  Section 7 of the
Management Agreement with respect to the ILA Portfolios provides that the ILA
Portfolios will indemnify the Adviser against certain liabilities; provided,
however, that such indemnification does not apply to any loss by reason of its
willful misfeasance, bad faith or gross negligence or the Adviser's reckless
disregard of its obligation under the Management Agreement.  The Management
Agreements are incorporated by reference to Exhibits (d)(1) through (d)(7);

Re:     Conservative Strategy Portfolio of Goldman Sachs Trust
        ------------------------------------------------------

Ladies and Gentlemen:

        We have acted as counsel for Goldman Sachs Trust, a Delaware business
trust (the "Trust"), in connection with the registration under the Securities
Act of 1933 of shares of beneficial interest ("Shares") representing interests
in an additional series, or fund, of the Trust known as the Conservative
Strategy Portfolio. The Conservative Strategy Portfolio has five classes of
shares: Class A Shares, Class B Shares, Class C Shares, Institutional Shares and
Service Shares. The Trust is authorized to issue an unlimited number of shares
of each class. These classes are hereinafter referred to as the "Shares."

        We have reviewed the Trust's Declaration of Trust, its by-laws, and 
certain resolutions adopted by its Board of Trustees, and have considered such 
other legal and factual matters as we have deemed appropriate.

        This opinion is based exclusively on the Delaware Business Trust Act and
the federal law of the United States of America.

        Based on the foregoing, we are of the opinion that the Shares, when 
issued against payment therefor as described in the Trust's prospectus relating 
thereto, will be legally issued, fully paid and non-assessable by the Trust, and
that the holders of the Shares will be entitled to the same limitation of
personal liability extended to stockholders of private corporations for profit
organized under the general corporation law of the State of Delaware (except
that we express no opinion as to such holders who are also trustees of the
Trust). Pursuant to Section 2 of Article VIII of the Declaration of Trust, the
Trustees have the power to cause shareholders, or shareholders of a particular
series or class, to pay certain custodian, transfer, servicing or similar agent
charges by

setting off the same against declared but unpaid dividends or by reducing Share 
ownership (or by both means).

     We hereby consent to the filing of this opinion with the Securities and 
Exchange Commission as part of a Post-Effective Amendment to the Registration 
Statement of the Trust. Except as provided in this paragraph, the opinion set 
forth above is expressed solely for the benefit of the addressee hereof in 
connection with the matters contemplated hereby and not be relied upon by, or 
filed with, any other person or entity or for any other purpose without our 
prior written consent.

                                        Very truly yours,
