Federal income tax.     
 
  The GOVERNMENT SELECT PORTFOLIO invests in selected short-term obligations
  of the U.S. Government, its agencies and instrumentalities the interest on

  both U.S. and foreign issuers, including certificates of deposit, bankers'
  acceptances, commercial paper and repurchase agreements.

  instruments the interest on which is exempt from regular Federal income
  tax.
   
Each Portfolio is advised by The Northern Trust Company ("Northern"). Shares
are sold and redeemed without any purchase or redemption charge imposed by the
Trust, although Northern and other institutions may charge their customers for
services provided in connection with their investments.

DESCRIPTION OF TRUST
 
The Trust is an open-end, management investment company registered under the
Investment Company Act of 1940 (the "1940 Act"). Each Portfolio consists of a
separate pool of assets with separate investment policies, as described below
under "Investment Information." All of the Portfolios are classified as
diversified companies. Northern serves as investment adviser, transfer agent
and custodian. Goldman Sachs serves as distributor and administrator.
   
Shares of the Portfolios are offered exclusively to institutional investors.
See "Investing--Purchase of Shares" and "Investing--Redemption of Shares" for
information on how to place purchase and redemption orders.     
   
Each Portfolio seeks to maintain a net asset value of $1.00 per share. The
assets of each Portfolio will be invested in dollar-denominated debt securities
with remaining maturities of thirteen months or less as defined by the
Securities and Exchange Commission (the "SEC"), and each Portfolio's dollar-
weighted average portfolio maturity will not exceed 90 days. All securities
acquired by the Portfolios will be determined by Northern, under guidelines
established by the Trust's Board of Trustees, to present minimal credit risks,
and will be "Eligible Securities" as defined by the SEC. There can be no
assurance that the Portfolios will be able to achieve a stable net asset value
on a continuous basis, or that they will achieve their investment objectives.
    
Investors should note that one or more of the Portfolios may purchase variable
and floating rate instruments, enter into repurchase agreements, reverse
repurchase agreements and securities loans, acquire U.S. dollar-denominated
instruments of foreign issuers and make limited investments in illiquid
securities and securities issued by other investment companies. These
investment practices involve investment risks of varying degrees. None of the
Portfolios will invest in instruments denominated in a foreign currency.
 
SUMMARY OF EXPENSES
   
The following table sets forth certain information regarding the annualized
operating expenses of the shares of the Portfolios incurred during the Trust's
last fiscal year. Hypothetical examples based on the table are also shown.

EXAMPLE OF EXPENSES. Based on the foregoing table, you would pay the following
expenses on a hypothetical $1,000 investment in shares, assuming a 5% annual
return and redemption at the end of each time period:

</TABLE>    
   
The costs and expenses included in the table and hypothetical example above are
based on actual amounts incurred for the fiscal year ended November 30, 1997.
During the Trust's last fiscal year, Northern voluntarily reduced its advisory
fee for the Government Select Portfolio (payable at the annual rate of .25% of
the Portfolio's average daily net assets) to .10% per annum. For the fiscal
period December 1, 1996 through April 30, 1997, Goldman Sachs charged an
administration fee with respect to each Portfolio during such period at the
annual rate of .25% of the first $100 million, .15% of the next $200 million,
 .075% of the next $450 million and .05% of any excess over $750 million of the
Portfolio's average daily net assets. For the period May 1, 1997 through
November 30, 1997, Goldman Sachs was entitled to an administration fee equal to
 .10% of the average daily net assets of each Portfolio. In addition, during the
fiscal year, Goldman Sachs reimbursed each Portfolio's expenses (including the
fees payable to Goldman Sachs as administrator, but excluding the fees payable
to Northern for its duties as adviser and certain extraordinary expenses) which
exceeded on an annualized basis .10% of the Portfolio's average daily net
assets for such fiscal year. The expense information in the table has,
accordingly, been presented to reflect these fee reductions and reimbursements.
Without the undertakings of Northern and Goldman Sachs, for the fiscal year
ended November 30, 1997, "Other Expenses" of the Government Select, Government,
Diversified Assets and Tax-Exempt Portfolios would have been .14%, .12%, .11%
and .14%, respectively; and "Total Operating Expenses" of the Government
Select, Government, Diversified Assets and Tax-Exempt Portfolios would have
been .39%, .37%, .36% and .39%, respectively. On April 1, 1998 upon the
offering of the Portfolios' Service Shares and Premier Shares, Goldman Sachs
will reimburse each Portfolio's expenses (including fees payable to Goldman
Sachs as administrator, but excluding the fees payable to Northern for its
duties as adviser and transfer agent, payments under the service plan for the
Portfolios' Service Shares and Premier Shares and certain extraordinary
expenses) which exceed on an annualized basis .10% of the Portfolio's average
daily

                             INVESTMENT INFORMATION
   
The investment objective of each Portfolio, other than the Tax-Exempt
Portfolio, is to seek to maximize current income to the extent consistent with
the preservation of capital and maintenance of liquidity by investing
exclusively in high quality money market instruments. The Tax-Exempt Portfolio
seeks to provide its 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 investment objective of a Portfolio may not be changed without
the vote of the majority of the outstanding shares of the particular Portfolio
(as defined below under "Organization"). Except as expressly noted below,
however, a Portfolio's investment policies may be changed without a vote of
shareholders.     
   
All securities acquired by the Portfolios will be determined by Northern, under
guidelines established by the Board of Trustees, to present minimal credit
risks and will be "Eligible Securities" as defined by the SEC. Eligible
Securities include, generally, (i) securities that either (a) have short-term
debt ratings at the time of purchase in the two highest rating categories by at
least two unaffiliated nationally recognized statistical rating organizations
("NRSROs") (or one NRSRO if the security is rated by only one NRSRO), or (b)
are issued or guaranteed by a person with such ratings, and (ii) securities
that are unrated (including securities of issuers that have long-term but not
short-term ratings) but are determined to be of comparable quality. Securities
that are in the highest short-term rating category as described above (and
unrated securities determined to be of comparable quality) are designated
"First Tier Securities." Under normal circumstances, the Government Select,
Government and Diversified Assets Portfolios intend to limit purchases of
securities to First Tier Securities. The Additional Statement includes a
description of applicable NRSRO ratings.     
 
Each Portfolio is managed so that the average maturity of all instruments in
the Portfolio (on a dollar-weighted basis) will not exceed 90 days. In no event
will the Portfolios purchase any securities which mature more than 13 months
from the date of purchase (except for certain variable and floating rate
instruments and securities collateralizing repurchase agreements). Securities
in which the Portfolios invest may not earn as high a level of income as long-
term or lower quality securities, which generally have greater market risk and
more fluctuation in market value.
 
GOVERNMENT SELECT PORTFOLIO
   
The Government Select Portfolio seeks to achieve its investment objective by
investing exclusively in securities issued or guaranteed as to principal and
interest by the U.S. Government, its agencies or instrumentalities. In making
investments, Northern will seek to acquire, under normal market conditions,
only those U.S. Government securities the interest on which is generally exempt
from state income taxation. Securities generally eligible for this exemption
include those issued by the U.S. Treasury and certain U.S. Government agencies
and instrumentalities, including the Federal Home Loan Bank and the Federal
Farm Credit Banks Funding Corp. The Portfolio intends to limit investments to
exempt U.S. Government securities. However, under extraordinary circumstances,
such as when appropriate exempt securities are unavailable, the Portfolio may
make investments in non-exempt U.S. Government securities and cash equivalents,
and may hold uninvested cash. See "Investing--Taxes" below for certain tax
considerations.     
 
 
                                       10
<PAGE>
 
GOVERNMENT PORTFOLIO
 
The Government Portfolio seeks to achieve its investment objective by investing
exclusively in:
     
  (A) Marketable securities issued or guaranteed as to principal and interest
  by the U.S. Government or by any of its agencies or instrumentalities and
  custodial receipts with respect thereto; and     
 
  (B) Repurchase agreements relating to the above instruments.
 
DIVERSIFIED ASSETS PORTFOLIO
 
In pursuing its investment objective, the Diversified Assets Portfolio may
invest in a broad range of government, bank and commercial obligations that are
available in the money markets. In particular, the Portfolio may invest in:
 
  (A) U.S. dollar-denominated obligations of U.S. banks with total assets in
  excess of $1 billion (including obligations of foreign branches of such
  banks);
 
  (B) U.S. dollar-denominated obligations of foreign commercial banks where
  such banks have total assets in excess of $5 billion;
 
  (C) High quality commercial paper and other obligations issued or
  guaranteed by U.S. and foreign corporations and other issuers rated (at the
  time of purchase) A-2 or higher by Standard & Poor's Ratings Group ("S&P"),
  Prime-2 or higher by Moody's Investors Service, Inc. ("Moody's"), Duff 2 or
  higher by Duff & Phelps Credit Rating Co. ("D&P"), F-2 or higher by Fitch
  IBCA, Inc. ("Fitch") or TBW-2 or higher by Thomson BankWatch, Inc. ("TBW");
 
  (D) Rated and unrated corporate bonds, notes, paper and other instruments
  that are of comparable quality to the commercial paper permitted to be
  purchased by the Portfolio;
 
  (E) Asset-backed securities (including interests in pools of assets such as
  mortgages, installment purchase obligations and credit card receivables);
 
  (F) Securities issued or guaranteed as to principal and interest by the
  U.S. Government or by its agencies or instrumentalities and custodial
  receipts with respect thereto;
     
  (G) U.S. dollar-denominated securities issued or guaranteed by one or more
  foreign governments or political subdivisions, agencies or
  instrumentalities thereof;     
 
  (H) Repurchase agreements relating to the above instruments; and
 
  (I) Securities issued or guaranteed by state or local governmental bodies.
 
TAX-EXEMPT PORTFOLIO
 
The Tax-Exempt Portfolio invests primarily in high quality short-term
instruments, the interest on which is, in the opinion of bond counsel for the
issuers, exempt from regular Federal income tax ("Municipal
 
                                       11
<PAGE>
 
Instruments"). Such opinions may contain various assumptions, qualifications or
exceptions that are reasonably acceptable to Northern. In particular, the
Portfolio may invest in:
 
  (A) Fixed and variable rate notes and similar debt instruments rated MIG-2,
  VMIG-2 or Prime-2 or higher by Moody's, SP-2 or A-2 or higher by S&P, AA or
  higher by D&P or F-2 or higher by Fitch;
 
  (B) Tax-exempt commercial paper and similar debt instruments rated Prime-2
  or higher by Moody's, A-2 or higher by S&P, Duff 2 or higher by D&P or F-2
  or higher by Fitch;
 
  (C) Rated and unrated municipal bonds, notes, paper or other instruments
  that are of comparable quality to the tax-exempt commercial paper permitted
  to be purchased by the Portfolio; and
 
  (D) Municipal bonds and notes which are guaranteed as to principal and
  interest by the U.S. Government or an agency or instrumentality thereof or
  which otherwise depend directly or indirectly on the credit of the United
  States.
   
As a matter of fundamental policy, changeable only with the approval of the
holders of a majority of the outstanding shares of the Tax-Exempt Portfolio, at
least 80% of the Portfolio's annual gross income will be derived from Municipal
Instruments except under extraordinary circumstances, such as when Northern
believes that market conditions indicate that the Portfolio should adopt a
temporary defensive posture by holding uninvested cash or investing in taxable
short-term securities ("Taxable Investments"). Taxable Investments will consist
exclusively of instruments that may be purchased by the Diversified Assets
Portfolio.     
 
DESCRIPTION OF SECURITIES AND COMMON INVESTMENT TECHNIQUES
 
BANK OBLIGATIONS. Domestic and foreign bank obligations in which the
Diversified Assets Portfolio may invest include certificates of deposit, bank
and deposit notes, bankers' acceptances and fixed time deposits. Such
obligations may be general obligations of the parent bank or may be limited to
the issuing branch or subsidiary by the terms of the specific obligation or by
government regulation. Total assets of a bank are determined on the basis of
the bank's most recent annual financial statements.
   
FOREIGN OBLIGATIONS. In addition to the obligations of foreign commercial banks
and foreign branches of U.S. banks, the Diversified Assets Portfolio may
acquire commercial obligations issued by Canadian corporations and Canadian
counterparts of U.S. corporations, as well as Europaper, which is U.S. dollar-
denominated commercial paper of a foreign issuer. The Diversified Assets
Portfolio may also invest in obligations issued or guaranteed by one or more
foreign governments or any of their political subdivisions, agencies or
instrumentalities. Such obligations may include debt obligations of
supranational entities, including international organizations (such as the
European Coal and Steel Community and the International Bank for Reconstruction
and Development (also known as the World Bank)) designated or supported by
governmental entities to promote economic reconstruction or development and
international banking institutions and related government agencies. Investments
by the Diversified Assets Portfolio in foreign issuer obligations will not
exceed 50% of the Portfolio's total assets measured at the time of purchase.
    
Obligations of foreign issuers acquired by the Diversified Assets Portfolio may
involve risks that are different than those of obligations of domestic issuers.
These risks include unfavorable political and economic developments, the
possible imposition of withholding taxes on interest income, possible seizure
or nationalization of foreign deposits, the possible establishment of exchange
controls, or the adoption of other
 
                                       12
<PAGE>
 
foreign governmental restrictions which might adversely affect the payment of
principal and interest on such obligations. In addition, foreign branches of
U.S. banks and foreign banks may be subject to less stringent reserve
requirements and to different accounting, auditing, reporting, and
recordkeeping standards than those applicable to domestic branches of U.S.
banks and, generally, there may be less publicly available information
regarding such issuers. The Trust could also encounter difficulties in
obtaining or enforcing a judgment against a foreign issuer (including a foreign
branch of a U.S. bank).
   
VARIABLE AND FLOATING RATE INSTRUMENTS. The Portfolios may purchase rated and
unrated variable and floating rate instruments, which may have stated
maturities in excess of the Portfolios' maturity limitations subject to
applicable SEC regulations. In the case of the Diversified Assets Portfolio,
such instruments may include variable amount master demand notes that permit
the indebtedness thereunder to vary in addition to providing for periodic
adjustments in the interest rate. Unrated variable and floating rate
instruments will be determined by Northern to be of comparable quality at the
time of the purchase to rated instruments purchasable by the Portfolios. The
absence of an active secondary market with respect to particular variable and
floating rate instruments could, however, make it difficult for a Portfolio to
dispose of the instruments if the issuer defaulted on its payment obligation or
during periods that the Portfolio is not entitled to exercise its demand
rights, and the Portfolio could, for these or other reasons, suffer a loss with
respect to such instruments. Variable and floating rate instruments held by a
Portfolio will be subject to the Portfolio's 10% limitation on illiquid
investments when the Portfolio may not demand payment of the principal amount
within seven days and a reliable trading market is absent.     
   
UNITED STATES GOVERNMENT OBLIGATIONS. Each Portfolio may invest in a variety of
U.S. Treasury obligations, consisting of bills, notes and bonds, which
principally differ only in their interest rates, maturities and time of
issuance. These obligations include "stripped" securities issued by the U.S.
Treasury and recorded in the Federal Reserve book-entry record-keeping system.
The Portfolios may also invest in other securities issued or guaranteed by the
U.S. Government, its agencies and instrumentalities. Obligations of certain
agencies and instrumentalities, such as the Government National Mortgage
Association, are supported by the full faith and credit of the U.S. Treasury;
others, such as those of the Export-Import Bank of the United States, are
supported by the right of the issuer to borrow from the Treasury; others, such
as those of the Federal National Mortgage Association, are supported by the
discretionary authority of the U.S. Government to purchase the agency's
obligations; still others are supported only by the credit of the
instrumentalities. No assurance can be given that the U.S. Government would
provide financial support to its agencies or instrumentalities if it is not
obligated to do so by law. There is no assurance that these commitments will be
undertaken or complied with in the future.     
 
Securities guaranteed as to principal and interest by the U.S. Government, its
agencies 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 or an agency or instrumentality thereof,
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.
 
CUSTODIAL RECEIPTS FOR TREASURY SECURITIES. The Portfolios (other than the
Government Select Portfolio) may also purchase participations in trusts that
hold U.S. Treasury securities (such as TIGRs and CATS) where the trust
participations evidence ownership in either the future interest payments or the
future principal
 
                                       13
<PAGE>
 
payments on the U.S. Treasury obligations. These participations are normally
issued at a discount to their "face value," and may exhibit greater price
volatility than ordinary debt securities because of the manner in which their
principal and interest are returned to investors. Investments by the Government
Portfolio in such custodial receipts will not exceed 35% of the value of that
Portfolio's total assets.
 
REPURCHASE AGREEMENTS. Each Portfolio may, in accordance with its investment
objective, policies and guidelines established by the Trust's Board of
Trustees, agree to purchase portfolio securities from financial institutions
subject to the seller's agreement to repurchase them at a mutually agreed upon
date and price ("repurchase agreements"). Although the securities subject to a
repurchase agreement may bear maturities exceeding 13 months, settlement for
the repurchase agreement will never be more than one year after a Portfolio's
acquisition of the securities and normally will be within a shorter period of
time. Securities subject to repurchase agreements are held either by the
Trust's custodian or subcustodian (if any), or in the Federal Reserve/Treasury
Book-Entry System. The seller under a repurchase agreement will be required to
maintain the value of the securities subject to the agreement in an amount
exceeding the repurchase price (including accrued interest). Default by the
seller would, however, expose a Portfolio to possible loss because of adverse
market action or delay in connection with the disposition of the underlying
obligations.
   
REVERSE REPURCHASE AGREEMENTS. The Government Select, Government and
Diversified Assets Portfolios may enter into reverse repurchase agreements
which involve the sale of money market securities held by a Portfolio, with an
agreement to repurchase the securities at an agreed upon price (including
interest) and date. A Portfolio will use the proceeds of reverse repurchase
agreements to purchase other money market securities either maturing, or under
an agreement to resell, at a date simultaneous with or prior to the expiration
of the reverse repurchase agreement. A Portfolio will utilize reverse
repurchase agreements, which may be viewed as borrowings (or leverage) by the
Portfolio, when it is anticipated that the interest income to be earned from
the investment of the proceeds of the transaction is greater than the interest
expense of the reverse repurchase transaction. During the time a reverse
repurchase agreement is outstanding, the Portfolio will segregate liquid assets
having a value at least equal to the repurchase price. A Portfolio may enter
into reverse repurchase agreements with banks, brokers and dealers, and has the
authority to enter into reverse repurchase agreements in amounts not exceeding
in the aggregate one-third of the Portfolio's total assets. See "Additional
Investment Information--Investment Restrictions" in the Additional Statement.
    
SECURITIES LENDING. The Portfolios may seek additional income from time to time
by lending their portfolio securities on a short-term basis to banks, brokers
and dealers under agreements requiring that the loans be secured by collateral
in the form of cash, cash equivalents or U.S. Government securities or
irrevocable bank letters of credit maintained on a current basis equal in value
to at least the market value of the securities loaned. A Portfolio may not make
such loans in excess of 33 1/3% of the value of the Portfolio's total assets
(including the loan collateral). Loans of securities involve risks of delay in
receiving additional collateral or in recovering the securities loaned, or
possibly loss of rights in the collateral should the borrower of the securities
become insolvent.
 
FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES. Each Portfolio may purchase
when-issued securities and make contracts to purchase or sell securities for a
fixed price at a future date beyond customary settlement time. Securities
purchased 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. Conversely, securities sold on a delayed-delivery or forward
 
                                       14
<PAGE>
 
   
commitment basis involve the risk that the value of the security to be sold may
increase prior to the settlement date. A Portfolio is required to segregate
liquid assets until three days prior to the settlement date, having a value
(determined daily) at least equal to the amount of the Portfolio's purchase
commitments, or to otherwise cover its position. Although a Portfolio would
generally purchase securities on a when-issued or forward commitment basis with
the intention of acquiring securities, the Portfolio may dispose of a when-
issued security or forward commitment prior to settlement if Northern deems it
appropriate to do so.     
   
INVESTMENT COMPANIES. In connection with the management of their daily cash
positions, the Portfolios may invest in securities issued by other investment
companies which invest in short-term, high-quality debt securities and which
determine their net asset value per share based on the amortized cost or penny-
rounding method of valuation ("money market funds"), and may invest in
securities issued by other investment companies consistent with their
investment objectives and policies. Investments by a Portfolio in other money
market funds and investment companies will be subject to the limitations of the
1940 Act as described in more detail in the Additional Statement. Although the
Portfolios do not expect to do so in the foreseeable future, each Portfolio is
authorized to invest substantially all of its assets in a single open-end
investment company or series thereof with substantially the same investment
objective, policies and fundamental restrictions as the Portfolio. As a
shareholder of another investment company, a Portfolio would bear, along with
other shareholders, its pro rata portion of the other investment company's
expenses, including advisory fees. These expenses would be in addition to the
advisory fees and other expenses the Portfolio bears directly in connection
with its own operations. The Trust has been advised by its counsel that exempt-
interest dividends received by the Tax-Exempt Portfolio as a shareholder of a
regulated investment company paying such dividends will receive the same
Federal tax treatment as interest received by the Portfolio on Municipal
Instruments held by it.     
 
MUNICIPAL AND RELATED INSTRUMENTS. Municipal Instruments in which the Tax-
Exempt Portfolio may invest include debt obligations issued by or on behalf of
states, territories and possessions of the United States and their political
subdivisions, agencies, authorities and instrumentalities.
 
Municipal Instruments may be issued to obtain funds for various public
purposes, including capital improvements, the refunding of outstanding
obligations, general operating expenses, and lending to other public agencies.
Among other instruments, the Portfolio may purchase short-term Tax Anticipation
Notes, Bond Anticipation Notes, Revenue Anticipation Notes, and other forms of
short-term loans. Such notes are issued with a short-term maturity in
anticipation of the receipt of tax funds, the proceeds of bond placements or
other revenues.
 
Municipal Instruments include both "general" and "revenue" obligations. General
obligations are secured by the issuer's pledge of its full faith, credit and
taxing power for the payment of principal and interest. Revenue obligations are
payable only 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 such as lease payments from the user of the facility
being financed. Industrial development bonds are in most cases revenue
securities and are not payable from the unrestricted revenues of the issuer.
Consequently, the credit quality of an industrial revenue bond is usually
directly related to the credit standing of the private user of the facility
involved.
 
The Tax-Exempt Portfolio may also invest in "moral obligation" bonds, which are
normally issued by special purpose public authorities. If the issuer of a moral
obligation bond is unable to meet its debt service
 
                                       15
<PAGE>
 
obligations from current revenues, it may draw on a reserve fund, the
restoration of which is a moral commitment but not a legal obligation of the
state or municipality which created the issuer.
 
Municipal bonds with a series of maturity dates are called Serial Bonds. The
Portfolio may purchase Serial Bonds and other long-term securities provided
that they have a remaining maturity meeting the Tax-Exempt Portfolio's maturity
requirements. The Portfolio may also purchase long-term variable and floating
rate bonds (sometimes referred to as "Put Bonds") where the Portfolio obtains
at the time of purchase the right to put the bond back to the issuer or a third
party at par at least every thirteen months. Put Bonds with conditional puts
(that is, puts which cannot be exercised if the issuer defaults on its payment
obligations) will present risks that are different than those of other
Municipal Instruments because of the possibility that the Portfolio might hold
a long-term Put Bond on which a default occurs following its acquisition by the
Portfolio.
 
The Tax-Exempt Portfolio may acquire securities in the form of custodial
receipts evidencing rights to receive a specific future interest payment,
principal payment or both on certain municipal obligations. 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,"
"Municipal Certificates of Accrual on Tax-Exempt Securities" ("M-CATS") and
"Municipal Zero-Coupon Receipts." The Portfolio may also purchase certificates
of participation that, in the opinion of counsel to the issuer, are exempt from
regular Federal income tax. Certificates of participation are a type of
floating or variable rate obligation that represents interests in a pool of
municipal obligations held by a bank.
 
The Tax-Exempt Portfolio may acquire "standby commitments" with respect to the
Municipal Instruments it holds. Under a standby commitment, a dealer agrees to
purchase at the Portfolio's option specified Municipal Instruments at a
specified price. The acquisition of a standby commitment may increase the cost,
and thereby reduce the yield, of the Municipal Instruments to which the
commitment relates. The Portfolio will acquire standby commitments solely to
facilitate portfolio liquidity and does not intend to exercise its rights
thereunder for trading purposes.
 
Municipal Instruments purchased by the Tax-Exempt Portfolio may be backed by
letters of credit or other forms of credit enhancement issued by foreign (as
well as domestic) banks and other financial institutions. The credit quality of
these banks and financial institutions could, therefore, cause loss to a
Portfolio that invests in Municipal Instruments. Letters of credit and other
obligations of foreign financial institutions may involve certain risks in
addition to those of domestic obligations. (See "Foreign Obligations" above.)
 
As stated, the Tax-Exempt Portfolio expects to invest primarily in Municipal
Instruments. However, the Portfolio may from time to time hold uninvested cash
or invest a portion of its assets in Taxable Investments. The Portfolio does
not intend to invest more than 25% of the value of its total assets 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. The Portfolio may, however, invest 25% or more
of its total assets in (a) Municipal Instruments the interest upon which is
paid solely from revenues of similar projects, and (b) industrial development
obligations. In addition, although the Tax-Exempt Portfolio does not expect to
do so during normal market conditions, it may invest more than 25% of the value
of its total assets in Municipal Instruments whose issuers are in the same
state. When a substantial percentage of the Portfolio's assets is invested in
instruments which are used to finance facilities involving a particular
industry, whose issuers are in the same state or which are otherwise related,
there is a possibility that an
 
                                       16
<PAGE>
 
   
economic, business or political development affecting one such instrument would
likewise affect the other related instruments.     
   
So long as other suitable Municipal Instruments are available for investment,
the Tax-Exempt Portfolio does not intend to invest in "private activity bonds"
the interest from which may be treated as an item of tax preference to
shareholders under the Federal alternative minimum tax.     
   
The Diversified Assets Portfolio may also invest up to 5% of its net assets
from time to time in municipal instruments or other securities issued by state
and local governmental bodies when, as a result of prevailing economic,
regulatory or other circumstances, the yield of such securities, on a pre-tax
basis, is comparable to that of other permitted short-term taxable investments.
Dividends paid on such investments will be taxable to shareholders.     
   
ISSUER DIVERSIFICATION. In accordance with current SEC regulations, each
Portfolio intends to limit investments in the securities of any single issuer
(excluding cash, cash items, certain repurchase agreements, U.S. Government
securities or securities of other investment companies) to not more than 5% of
the value of its total assets at the time of purchase, except that (a) 25% of
the value of the total assets of each Portfolio may be invested in the
securities of any one issuer for a period of up to three Business Days; and (b)
securities subject to certain unconditional guarantees are subject to different
diversification requirements as described in the Additional Statement. In
addition, the Portfolios will limit their investments in securities that are
not First Tier Securities as prescribed by SEC regulations.     
   
DERIVATIVE INSTRUMENTS. Each Portfolio may also purchase certain "derivative"
instruments. "Derivative" instruments are instruments that derive value from
the performance of underlying assets, interest rates or indices, and include
(but are not limited to) various structured debt obligations (including certain
variable and floating rate instruments). Derivative instruments present, to
varying degrees, market risk that the performance of the underlying assets,
interest rates or indices will decline; credit risk that the dealer or other
counterparty to the transaction will fail to pay its obligations; volatility
risk that, if interest rates change adversely, the value of the derivative
instrument will decline more than the assets, rates or indices on which it is
based; liquidity risk that a Portfolio will be unable to sell a derivative
instrument when it wants because of lack of market depth or market disruption;
pricing risk that the value of a derivative instrument will not correlate
exactly to the value of the underlying assets, rates or indices on which it is
based; and operations risk that loss will occur as a result of inadequate
systems and controls, human error or otherwise. Some derivative instruments are
more complex than others, and for those instruments that have been developed
recently, information is lacking regarding their actual performance over
complete market cycles. Northern will evaluate the risks presented by the
derivative instruments purchased by the Portfolios, and will determine, in
connection with its day-to-day management of the Portfolios, how they will be
used in furtherance of the Portfolios' investment objectives. It is possible,
however, that Northern's evaluations will prove to be inaccurate or incomplete
and, even when accurate and complete, it is possible that the Portfolios will,
because of the risks discussed above, incur loss as a result of their
investments in derivative instruments.     
 
ILLIQUID OR RESTRICTED SECURITIES. A Portfolio will not invest more than 10% of
its net assets in securities which are illiquid, including repurchase
agreements and time deposits that do not provide for payment to the Trust
within seven days after notice and certificates of participation for which
there is no readily available secondary
 
                                       17
<PAGE>
 
   
market and certain securities which are subject to trading restrictions because
they are not registered under the Securities Act of 1933 (the "1933 Act").     
   
If otherwise consistent with their investment objectives and policies, the
Portfolios may purchase commercial paper issued pursuant to Section 4(2) of the
1933 Act and securities that are not registered under the 1933 Act but can be
sold to "qualified institutional buyers" in accordance with Rule 144A under the
1933 Act. These securities will not be considered illiquid so long as Northern
determines, under guidelines approved by the Trust's Board of Trustees, that an
adequate trading market exists. This practice could increase the level of
illiquidity during any period that qualified institutional buyers become
uninterested in purchasing these securities.     
   
MISCELLANEOUS. Although the Portfolios will generally not seek profits through
short-term trading, each Portfolio may dispose of any portfolio security prior
to its maturity if, on the basis of a revised credit evaluation of the issuer
or other considerations, Northern believes such disposition is advisable.
Subsequent to its purchase, a portfolio security may be assigned a lower rating
or cease to be rated. Such an event would not necessarily require the
disposition of the security, if the continued holding of the security is
determined to be in the best interest of the Portfolio and its shareholders.
    
In determining the creditworthiness of the issuers of portfolio securities that
may be purchased and held by the Portfolios, Northern gathers and reviews
historical financial data and, through the use of a proprietary software
computer program, analyzes and attempts to assess the fundamental strengths and
weaknesses of individual issuers, industries and market sectors. Exposure
limits are established by Northern for each security in conformance with the
objectives and policies stated in this Prospectus, and are thereafter adjusted
periodically in response to changes in relevant credit factors.
          
Pursuant to an SEC order, each Portfolio may engage in principal transactions
effected in the ordinary course of business with Goldman Sachs.     
 
INVESTMENT RESTRICTIONS
   
The Portfolios are subject to certain investment restrictions which, as
described in more detail in the Additional Statement, are fundamental policies
that cannot be changed without the approval of a majority of the outstanding
shares of a Portfolio. Each Portfolio will limit its investments so that less
than 25% of the Portfolio's total assets will be invested in the securities of
issuers in any one industry (with certain limited exceptions). Each Portfolio
may borrow money from banks for temporary or emergency purposes or to meet
redemption requests, provided that the Portfolio maintains asset coverage of at
least 300% for all such borrowings.     
 
                               TRUST INFORMATION
 
BOARD OF TRUSTEES
 
The business and affairs of the Trust and each Portfolio are managed under the
direction of the Trust's Board of Trustees. The Additional Statement contains
the name of each Trustee and background information regarding the Trustees.

INVESTMENT ADVISER, TRANSFER AGENT AND CUSTODIAN
   
Northern, which has offices at 50 S. LaSalle Street, Chicago, Illinois 60675,
serves as investment adviser, transfer agent and custodian for each Portfolio.
As transfer agent, Northern performs various shareholder servicing functions,
and any shareholder inquiries should be directed to it.     
   
Northern, a member of the Federal Reserve System, is an Illinois state-
chartered commercial bank and the principal subsidiary of Northern Trust
Corporation, a bank holding company. Northern was formed in 1889 with
capitalization of $1 million. As of December 31, 1997, Northern Trust
Corporation and its subsidiaries had approximately $25.3 billion in assets,
$16.4 billion in deposits and employed over 7,553 persons.     
   
Northern and its affiliates administered in various capacities (including as
master trustee, investment manager or custodian) approximately $1 trillion of
assets as of December 31, 1997, including approximately $196.5 billion of
assets for which Northern and its affiliates had investment management
responsibility.     
 
Under its Advisory Agreement with the Trust, Northern, subject to the general
supervision of the Trust's Board of Trustees, is responsible for making
investment decisions for the Portfolios and placing purchase and sale orders
for portfolio securities. Northern is also responsible for monitoring and
preserving the records required to be maintained under the regulations of the
SEC (with certain exceptions unrelated to its activities for the Trust). As
compensation for its advisory services and its assumption of related expenses,
Northern is entitled to a fee, computed daily and payable monthly, at an annual
rate of .25% of the average daily net assets of each Portfolio.
 
For serving as investment adviser during the fiscal year ended November 30,
1997, Northern earned fees paid by the Government Portfolio, the Diversified
Assets Portfolio and the Tax-Exempt Portfolio at the rate of .25% (per annum)
of each Portfolio's average daily net assets. For serving as investment adviser
during the fiscal year ended November 30, 1997, Northern earned fees (after
waivers) paid by the Government Select Portfolio at the rate of .10% (per
annum) of its average daily net assets.
   
Northern also receives compensation as the Trust's custodian and transfer agent
under separate agreements. The fees payable by the Portfolios for these
services are described in the Additional Statement. Different transfer agency
fees are payable with respect to the Portfolios' different share classes.     
   
YEAR 2000     
   
Like every other business dependent upon computerized information processing,
Northern Trust Corporation ("Northern Trust") must deal with "Year 2000"
issues, which stem from using two digits to reflect the year in computer
programs and data. Computer programmers and other designers of equipment that
use microprocessors have long abbreviated dates by eliminating the first two
digits of the year under the assumption that those two digits will always be
19. As the Year 2000 approaches, many systems may be unable to accurately
process certain date-based information, which could cause a variety of
operational problems for businesses.     
   
Northern Trust's data processing software and hardware provide essential
support to virtually all of its business units, including the units that
provide services to the Trust, so successfully addressing Year 2000 issues is
of the highest importance. Failure to complete renovation of the critical
systems used by Northern     
 
                                       19
<PAGE>
 
   
on a timely basis could have a materially adverse effect on its ability to
provide such services -- as could Year 2000 problems experienced by others.
Although the nature of the problem is such that there can be no complete
assurance it will be successfully resolved, Northern Trust has indicated that a
renovation and risk mitigation program is well under way and that it has a
dedicated Year 2000 Project Team whose members have significant systems
development and maintenance experience. Northern Trust's Year 2000 Project
includes a comprehensive testing plan. Northern Trust has advised the Trust
that it expects to complete work on its critical systems by December 31, 1998,
so that testing with outside parties may be conducted during 1999.     
   
Northern Trust also will have a program to monitor and assess the efforts of
other parties. However, it cannot control the success of those efforts.
Contingency plans are being established where appropriate to provide Northern
Trust with alternatives in case these entities experience significant Year 2000
difficulties which impact Northern Trust.     
 
ADMINISTRATOR AND DISTRIBUTOR
 
Goldman Sachs, 85 Broad Street, New York, New York 10004, acts as administrator
and distributor for the Portfolios. Subject to the limitations described below,
as compensation for its administrative services (which include supervision with
respect to the Trust's non-investment advisory operations) and the assumption
of related expenses, Goldman Sachs is entitled to a fee from each Portfolio,
computed daily and payable monthly, at an annual rate of .10% of the average
daily net assets of each Portfolio. No compensation is payable by the Trust to
Goldman Sachs for its distribution services.
   
In addition, Goldman Sachs has agreed that it will reimburse each Portfolio for
its expenses (including the fees payable to Goldman Sachs as administrator, but
excluding the fees payable to Northern for its duties as investment adviser and
transfer agent, payments under the service plan for the Portfolios' Service
Share and Premier Share classes and extraordinary expenses such as interest,
taxes and indemnification expenses) which exceed on an annualized basis .10% of
such Portfolio's average daily net assets for any fiscal year. In addition, as
of the date of this Prospectus, Northern will continue to voluntarily reduce
its advisory fee for the Government Select Portfolio. The result of these
reimbursements and fee reductions will be to increase the yields of the
Portfolios during the periods for which the reimbursements and reductions are
made.     
   
EXPENSES     
   
Except as set forth above and in the Additional Statement under "Additional
Trust Information," each Portfolio is responsible for the payment of its
expenses. Such expenses include without limitation, the fees and expenses
payable to Northern and Goldman Sachs, fees for the registration or
qualification of Portfolio shares under Federal or state securities laws,
expenses of the organization of the Portfolio, taxes, 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 Trust for violation of any law, legal,
tax and auditing fees and expenses, expenses of preparing and printing
prospectuses, statements of additional information, proxy materials, reports
and notices and the printing and distributing of the same to the Trust's
shareholders and regulatory authorities, compensation and expenses of its
Trustees, expenses of industry organizations such as the Investment Company
Institute, miscellaneous expenses and extraordinary expenses incurred by the
Trust.

                                   INVESTING
   
PURCHASE OF SHARES     
   
Shares are offered to Northern, its affiliates and other institutions and
organizations, including certain defined contribution plans having at least $30
million in assets or annual contributions of at least $5 million (the
"Institutions"), acting on behalf of their customers, clients, employees,
participants and others (the "Customers") and for their own account. Shares of
the Portfolios are sold on a continuous basis by the Trust's distributor,
Goldman Sachs, to Institutions that either maintain certain institutional
accounts with Northern or its affiliates or invest an aggregate of at least $5
million in one or more Portfolios of the Trust. Goldman Sachs has established
procedures for purchasing shares in order to accommodate different types of
Institutions.     
   
PURCHASE OF SHARES THROUGH INSTITUTIONAL ACCOUNTS. Any Institution maintaining
an institutional account at Northern or an affiliate may make purchases through
such institutional account either by directing automatic investment of cash
balances in excess of certain agreed upon amounts or by directing investments
from time to time on a non-automatic basis. The nature of an Institution's
relationship with Northern or an affiliate will determine whether the
Institution maintains an institutional account as well as the procedures
available for purchases. Institutions should contact Northern or an affiliate
for further information in this regard. There is no minimum initial investment
for Institutions that maintain institutional accounts with Northern or its
affiliates.     
   
PURCHASE OF SHARES DIRECTLY FROM THE TRUST. An Institution that purchases
shares directly may do so by means of one of the following procedures, provided
it makes an aggregate minimum initial investment of $5 million in one or more
Portfolios of the Trust:     
     
  PURCHASE BY MAIL. An Institution desiring to purchase shares of a Portfolio
  by mail should mail a check or Federal Reserve draft payable to the
  specific Portfolio together with a completed and signed new account
  application to The Benchmark Funds, c/o The Northern Trust Company, P.O.
  Box 75943, Chicago, Illinois 60675-5943. An application will be incomplete
  if it does not include a corporate resolution with the corporate seal and
  secretary's certification, or other acceptable evidence of authority. If an
  Institution desires to purchase the shares of more than one Portfolio, the
  Institution should send a separate check for each Portfolio. All checks
  must be payable in U.S. dollars and drawn on a bank located in the United
  States. A $20 charge will be imposed if a check does not clear. The
  proceeds of redemptions of shares purchased by check may be delayed up to
  15 days to allow the Trust to determine that the check has cleared and been
  paid. Cash and third party checks are not acceptable for the purchase of
  Trust shares.     
     
  PURCHASE BY TELEPHONE. An Institution desiring to purchase shares of a
  Portfolio by telephone should call Northern acting as the Trust's transfer
  agent ("Transfer Agent") at 1-800-637-1380. Please be prepared to identify
  the name of the Portfolio with respect to which shares are to be purchased
  and the manner of payment. Please indicate whether a new account is being
  established or an additional payment is being made to an existing account.
  If an additional payment is being made to an existing account, please
  provide the Institution's name and Portfolio Account Number. Purchase
  orders are effected upon     
 
                                       21
<PAGE>
 
  receipt by the Transfer Agent of Federal funds or other immediately
  available funds in accordance with the terms set forth below.
     
  PURCHASE BY WIRE OR ACH TRANSFER. An Institution desiring to purchase
  shares of a Portfolio by wire or ACH Transfer should call the Transfer
  Agent at 1-800-637-1380 for instructions if it is not making an additional
  payment to an existing account. An Institution that wishes to add to an
  existing account should wire Federal funds or effect an ACH Transfer to:
      
                      The Northern Trust Company
                      Chicago, Illinois

  For other information concerning requirements for the purchase of shares,
  call the Transfer Agent at 1-800-637-1380.     
   
EFFECTIVE TIME OF PURCHASES. Except as provided below under "Miscellaneous," a
purchase order for shares placed with the Transfer Agent by 1:00 p.m., Chicago
time, on a Business Day (as defined under "Miscellaneous") will be effected on
that Business Day at the net asset value next determined on that day with
respect to a Portfolio, provided that the Transfer Agent receives the purchase
price in Federal funds or other immediately available funds prior to 1:00 p.m.,
Chicago time, on the same Business Day such order is received. Orders received
after 1:00 p.m. on a Business Day will be effected at the net asset value next
determined on the following Business Day, provided that payment is received as
provided herein. Purchase orders received on a non-Business Day will not be
executed until the following Business Day in accordance with the foregoing
procedures. An order generated pursuant to an automatic investment direction of
an Institution that has an institutional account with Northern or its
affiliates will normally be placed either on the Business Day that funds are
available in such account or on the first Business Day thereafter, depending
upon the terms of the Institution's automatic investment arrangements. Shares
of a Portfolio are entitled to the dividends declared by the Portfolio
beginning on the Business Day the purchase order is executed.     
   
MISCELLANEOUS PURCHASE INFORMATION. Shares are purchased without a sales charge
imposed by the Trust. The minimum initial investment is $5 million for
Institutions that invest directly in one or more investment portfolios of the
Trust. The Trust reserves the right to waive this minimum and to determine the
manner in which the minimum investment is satisfied. There is no minimum for
subsequent investments.     
 
Institutions intending to place a purchase order of $5 million or more directly
with the Trust through the Transfer Agent are requested to give advance notice
to the Transfer Agent no later than 11:00 a.m. Chicago Time on a Business Day
in order to assist in the processing of the order.
 
See "Miscellaneous" below for information on when the Trust may advance the
time by which purchase requests must be received.
   
Institutions may impose minimum investment and other requirements on Customers
purchasing shares through them. Depending on the terms governing the particular
account, Institutions may impose account     
 
                                       22

charges such as asset allocation fees, account maintenance fees, compensating
balance requirements or other charges based upon account transactions, assets
or income, which will have the effect of reducing the net return on an
investment in a Portfolio. The exercise of voting rights and the delivery to
Customers of shareholder communications from the Trust will be governed by the
Customers' account agreements with the Institutions. Customers should read this
Prospectus in connection with any relevant agreement describing the services
provided by an Institution and any related requirements and charges, or contact
the Institution at which the Customer maintains its account for further
information.     
   
Institutions that purchase shares on behalf of Customers are responsible for
transmitting purchase orders to the Transfer Agent and delivering required
Federal funds on a timely basis. An Institution will be responsible for all
losses and expenses of a Portfolio as a result of a check that does not clear,
an ACH transfer that is rejected, or any other failure to make payment in the
time and manner described above, and Northern may redeem shares from an account
it maintains to protect the Portfolio and Northern against loss. The Trust
reserves the right to reject any purchase order. In those cases in which an
Institution pays for shares by check, Federal funds will generally become
available two Business Days after a purchase order is received. Federal
regulations require that the Transfer Agent be furnished with a taxpayer
identification number upon opening or reopening an account. Purchase orders
without such a number or an indication that a number has been applied for will
not be accepted. If a number has been applied for, the number must be provided
and certified within sixty days of the date of the order.     
   
Payment for shares of the Portfolio may, in the discretion of Northern, be made
in the form of securities that are permissible investments for the Portfolio.
For further information about the terms of such purchases, see the Additional
Statement.     
   
In the interests of economy and convenience, certificates representing shares
of the Portfolios are not issued.     
 
Institutions investing in the Portfolios on behalf of their Customers should
note that state securities laws regarding the registration of dealers may
differ from the interpretations of Federal law and such institutions may be
required to register as dealers pursuant to state law.
   
Northern may, at its own expense, provide compensation to certain dealers and
other financial intermediaries who provide services to their Customers who
invest in the Trust or whose Customers purchase significant amounts of shares
of a Portfolio. The amount of such compensation may be made on a one-time
and/or periodic basis, and may represent all or a portion of the annual fees
that are earned by Northern as investment adviser to such Portfolio (after
adjustments) and are attributable to shares held by such Customers. Such
compensation will not represent an additional expense to the Trust or its
shareholders, since it will be paid from assets of Northern or its affiliates.
       
REDEMPTION OF SHARES     
   
Institutions may redeem shares of a Portfolio through procedures established by
Northern and its affiliates in connection with the requirements of their
institutional accounts or through procedures set forth herein with respect to
Institutions that invest directly.     
 
                                       23
<PAGE>
 
   
REDEMPTION OF SHARES THROUGH INSTITUTIONAL ACCOUNTS. Institutions may redeem
shares in their institutional accounts at Northern or its affiliates. For
Institutions that participate in an automatic investment service described
above under "Purchase of Shares," Northern or its affiliates will calculate on
each Business Day the number of shares that need to be redeemed in order to
bring the Institution's account up to any agreed upon minimum amount.
Redemption requests on behalf of an Institution will normally be placed either
on the Business Day the redemption amount is calculated or on the first
Business Day thereafter, depending upon the terms of the Institution's
automatic investment arrangements. In the latter case, however, Northern or its
affiliates normally will provide funds by provisionally crediting the
institutional account of the Institution on the Business Day on which the
calculation is made. The nature of an Institution's relationship with Northern
or an affiliate will determine whether the Institution maintains an
"institutional account" as well as the procedures available for redemptions.
Institutions should contact Northern or an affiliate for further information in
this regard.     
   
REDEMPTION OF SHARES DIRECTLY. Institutions that purchase shares directly from
the Trust through the Transfer Agent may redeem all or part of their Portfolio
shares in accordance with the procedures set forth below.     
     
  REDEMPTION BY MAIL. An Institution may redeem shares by sending a written
  request to The Benchmark Funds, c/o The Northern Trust Company, P.O. Box
  75943, Chicago, Illinois 60675-5943. Redemption requests must be signed by
  a duly authorized person, and must state the number of shares or the dollar
  amount to be redeemed and identify the Portfolio Account Number. See "Other
  Requirements."     
     
  REDEMPTION BY TELEPHONE. An Institution may redeem shares by placing a
  redemption order by telephone by calling the Transfer Agent at 1-800-637-
  1380. During periods of unusual economic or market changes, telephone
  redemptions may be difficult to implement. In such event, shareholders
  should follow procedures outlined above under "Redemption by Mail."     
     
  REDEMPTION BY WIRE. If an Institution has given authorization for expedited
  wire redemption, shares can be redeemed and the proceeds sent by Federal
  wire transfer to a single previously designated bank account. The minimum
  amount which may be redeemed by this method is $10,000. The Trust reserves
  the right to change or waive this minimum or to terminate the wire
  redemption privilege. See "Other Requirements."     
     
  TELEPHONE PRIVILEGE. An Institution that has notified the Transfer Agent in
  writing of the Institution's election to redeem or exchange shares by
  placing an order by telephone may do so by calling the Transfer Agent at
  1-800-637-1380. Neither the Trust nor its Transfer Agent will be
  responsible for the authenticity of instructions received by telephone that
  are reasonably believed to be genuine. To the extent that the Trust fails
  to use reasonable procedures to verify the genuineness of telephone
  instructions, it or its service providers may be liable for such
  instructions that prove to be fraudulent or unauthorized. In all other
  cases, the shareholder will bear the risk of loss for fraudulent telephone
  transactions. However, the Transfer Agent has adopted procedures in an
  effort to establish reasonable safeguards against fraudulent telephone
  transactions. The proceeds of redemption orders received by telephone will
  be sent by check, by wire or by transfer pursuant to proper instruments.
  All checks will be made payable to the shareholder of record and mailed
  only to the shareholder's address of record. See "Other Requirements."     
 
                                       24
<PAGE>
 
  Additionally, the Transfer Agent utilizes recorded lines for telephone
  transactions and retains such tape recordings for six months, and will
  request a form of identification if such identification has been furnished
  to the Transfer Agent or the Trust.
     
  OTHER REQUIREMENTS. A change of wiring instructions and a change of the
  address of record may be effected only by a written request to the Transfer
  Agent accompanied by (i) a corporate resolution which evidences authority
  to sign on behalf of the Institution (including the corporate seal and
  secretary's certification), (ii) a signature guarantee by a financial
  institution that is a participant in the Stock Transfer Agency Medallion
  Program ("STAMP") in accordance with rules promulgated by the SEC (a
  signature notarized by a notary public is not acceptable) or (iii) such
  other means or evidence of authority as may be acceptable to the Transfer
  Agent. A redemption request by mail will not be effective unless signed by
  a person authorized by the corporate resolution or other acceptable
  evidence of authority on file with the Transfer Agent.     
   
EXCHANGE PRIVILEGE. Institutions and, to the extent permitted by their account
agreements, Customers, may, after appropriate prior authorization, exchange
shares of a Portfolio having a value of at least $1,000 for shares of certain
other portfolios of the Trust as to which the Institution or Customer maintains
an existing account with an identical title.     
   
Exchanges will be effected by a redemption of shares of the Portfolio held and
the purchase of shares of the portfolio acquired. Customers of Institutions
should contact their Institutions for further information regarding the Trust's
exchange privilege and Institutions should contact the Transfer Agent as
appropriate. Customers and Institutions exercising the exchange privilege
should read the relevant prospectus prior to making an exchange. The Trust
reserves the right to modify or terminate the exchange privilege at any time
upon 60 days' written notice to shareholders of record and to reject any
exchange request. Exchanges are only available in states where an exchange can
legally be made.     
   
EFFECTIVE TIME OF REDEMPTIONS AND EXCHANGES. Redemption orders of Portfolio
shares are effected at the net asset value per share next determined after
receipt in good order by the Transfer Agent. Good order means that the request
includes the following: the account number and Portfolio name; the amount of
the transaction (as specified in dollars or shares); and the signature of a
duly authorized person (except for telephone and wire redemptions). See
"Investing--Redemption of Shares--Other Requirements." Exchange orders are
effected at the net asset value per share next determined after receipt in good
order by the Transfer Agent. Payment for redeemed shares for which a redemption
order is received by Northern with respect to an institutional account it
maintains or the Transfer Agent as of 1:00 p.m., Chicago time, on a Business
Day normally will be made in Federal funds or other immediately available funds
wired or sent by check to the redeeming shareholder or, if selected, the
shareholder's institutional account with Northern on that Business Day.
Redemption orders received after 1:00 p.m. will be effected the next Business
Day. Proceeds for redemption orders received on a non-Business Day will
normally be sent on the next Business Day after receipt in good order.     
   
MISCELLANEOUS REDEMPTION AND EXCHANGE INFORMATION. All redemption proceeds will
be sent by check unless Northern or the Transfer Agent is directed otherwise.
The ACH system may be utilized for payment of redemption proceeds. Redemption
of shares may not be effected if a shareholder has failed to submit a completed
and properly executed (with corporate resolution or other acceptable evidence
of authority) new     
 
                                       25

account application. Institutions intending to place exchange and redemption
orders for same day proceeds of $5 million or more directly with the Trust
through the Transfer Agent are requested to give advance notice to the Transfer
Agent no later than 11:00 a.m. Chicago Time on a Business Day. The proceeds of
redemptions of shares purchased by check may be delayed up to 15 days to allow
the Trust to determine that the check has cleared and been paid. The Trust
reserves the right to defer crediting, sending or wiring redemption proceeds
for up to seven days after receiving a redemption order if, in its judgment, an
earlier payment could adversely affect a Portfolio.     
 
See "Miscellaneous" below for information on when the Trust may advance the
time by which redemption and exchange requests must be received.
   
The Trust may require any information reasonably necessary to ensure that a
redemption has been duly authorized. Dividends on shares are earned through and
including the day prior to the day on which they are redeemed.     
   
It is the responsibility of Institutions acting on behalf of Customers to
transmit redemption orders to the Transfer Agent and to credit Customers'
accounts with the redemption proceeds on a timely basis. If a Customer has
agreed with a particular Institution to maintain a minimum balance in his
account at such Institution and the balance in such account falls below that
minimum, such Customer may be obliged to redeem all or part of his shares to
the extent necessary to maintain the required minimum balance.     
 
DISTRIBUTIONS
   
Shareholders of each Portfolio are entitled to dividends and distributions
arising from the net income and capital gains, if any, earned on investments
held by the particular Portfolio. Dividends from each Portfolio's net income
are declared daily as a dividend to shareholders of record at the close of
business on the days the dividends are declared (or 3:00 p.m., Chicago time, on
non-Business Days).     
 
Net income of each Portfolio includes interest accrued on the assets of such
Portfolio less the estimated expenses charged to such Portfolio. Net realized
short-term capital gains of each Portfolio will be distributed at least
annually. The Portfolios do not expect to realize net long-term capital gains.
   
Dividends declared during a calendar month will be paid as soon as practicable
following the end of the month, except that such dividends will be paid
promptly upon a total redemption of shares in any account not subject to a
standing order for the purchase of additional shares. All distributions are
paid by each Portfolio in cash or are automatically reinvested (without any
sales charge) in additional shares of the same Portfolio. Arrangements may be
made for the crediting of such distributions to a shareholder's account with
Northern, its affiliates or its correspondent banks.     
 
TAXES
   
Management of the Trust intends that each Portfolio will qualify as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended (the "Code") as long as such qualification is in the best interest of
the Portfolio's shareholders. Such qualification generally relieves each
Portfolio of liability for Federal income taxes to the extent its earnings are
distributed in accordance with the Code, but shareholders,     
 
                                       26
<PAGE>
 
unless otherwise exempt, will pay income taxes on amounts so distributed
(except distributions that constitute "exempt-interest dividends" or that are
treated as a return of capital). Dividends paid from net short-term capital
gains are treated as ordinary income dividends. None of the Portfolios'
distributions will be eligible for the corporate dividends received deduction.
   
The Tax-Exempt Portfolio intends to pay substantially all of its dividends as
"exempt-interest dividends." Investors in the Portfolio should note, however,
that taxpayers are required to report the receipt of tax-exempt interest and
"exempt-interest dividends" on their Federal income tax returns and that in two
circumstances such amounts, while exempt from regular Federal income tax, are
taxable to persons subject to alternative minimum taxes. First, tax-exempt
interest and "exempt-interest dividends" derived from certain private activity
bonds issued after August 7, 1986 generally will constitute an item of tax
preference for corporate and noncorporate taxpayers in determining alternative
minimum tax liability. Second, all tax-exempt interest and "exempt-interest
dividends" must be taken into account by corporate taxpayers in determining
certain adjustments for alternative minimum tax purposes. Shareholders who are
recipients of Social Security Act or Railroad Retirement Act benefits should
note that tax-exempt interest and "exempt-interest dividends" will be taken
into account in determining the taxability of their benefit payments. To the
extent, if any, that dividends paid by the Tax-Exempt Portfolio to its
shareholders are derived from taxable interest or from capital gains, such
dividends will be subject to Federal income tax, whether received in cash or
reinvested in additional shares.     
   
The Tax-Exempt Portfolio will determine annually the percentages of its net
investment income which are exempt from the regular Federal income tax, which
constitute an item of tax preference for purposes of the Federal alternative
minimum tax, and which are fully taxable and will apply such percentages
uniformly to all distributions declared from net investment income during that
year. These percentages may differ significantly from the actual percentages
for any particular day.     
   
The Trust will send written notices to shareholders annually regarding the tax
status of distributions made by each Portfolio. Dividends declared in October,
November or December of any year payable to shareholders of record on a
specified date in those months will be deemed for Federal tax purposes to have
been paid by a Portfolio and to have been received by the shareholders on
December 31 of that year, if the dividends are actually paid during the
following January.     
   
The foregoing discussion is only a brief summary of some of the important tax
considerations generally affecting the Portfolios and their shareholders and is
not intended as a substitute for careful tax planning. Accordingly, investors
should consult their tax advisers with specific reference to their own Federal,
state and local tax situation. In particular, although the Government Select
Portfolio intends to invest primarily in U.S. Government securities the
interest on which is generally exempt from state income taxation, an investor
should consult his or her own tax adviser to determine whether distributions
from the Portfolio are exempt from state income taxation in the investor's own
situation. Similarly, dividends paid by the Portfolios may be taxable to
investors under state or local law as dividend income even though all or a
portion of such dividends may be derived from interest on obligations which, if
realized directly, would be exempt from such income taxes. Future legislative
or administrative changes or court decisions may materially affect the tax
consequences of investing in one or more of the Portfolios.     
 
                                       27
<PAGE>
 
                                NET ASSET VALUE
   
The net asset value per share of each Portfolio for purposes of purchases and
redemptions is calculated by Northern as of 3:00 p.m., Chicago time,
immediately after the declaration of net income earned by shareholders of
record, on each Business Day (as defined below under "Miscellaneous"), except
for days during which no shares are tendered to the Portfolio for redemption
and no orders to purchase or sell shares are received by the Portfolio and
except for days on which there is an insufficient degree of trading in the
Portfolio's securities for changes in the value of such securities to
materially affect the net asset value per share. The time at which the net
asset value per share of a Portfolio is calculated may be advanced on days on
which Northern or the securities markets close early. See "Miscellaneous"
below. Currently, each Portfolio offers three separate classes of shares. Net
asset value per share of each class of each Portfolio is calculated by adding
the value of all securities and other assets belonging to the Portfolio that
are allocated to such class, subtracting the liabilities charged to that class
and dividing by the number of outstanding shares of that class.     
   
In seeking to maintain a net asset value of $1.00 per share with respect to
each Portfolio for purposes of purchases and redemptions, the Trust values the
portfolio securities held by a Portfolio pursuant to the amortized cost
method. Under this method, 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 of maturity. See "Amortized Cost
Valuation" in the Additional Statement. There can be no assurance that a
Portfolio will be able at all times to maintain a net asset value per share of
$1.00.     
 
                            PERFORMANCE INFORMATION
 
From time to time the Portfolios may advertise their "yields" and "effective
yields" and the Government Select Portfolio and Tax-Exempt Portfolio may
advertise their "tax-equivalent yields." These yield figures will fluctuate,
are based on historical earnings and are not intended to indicate future
performance. "Yield" refers to the net investment income generated by an
investment in the Portfolio over a seven-day period identified in the
advertisement. This net investment income is then "annualized." That is, the
amount of net investment income generated by the investment during that week
is assumed to be generated each week over a 52-week period and is shown as a
percentage of the investment. "Effective yield" is calculated similarly but,
when annualized, the net investment income earned by an investment in the
Portfolio is assumed to be reinvested. The "effective yield" will be slightly
higher than the "yield" because of the compounding effect of this assumed
reinvestment. The "tax-equivalent yield" demonstrates the level of taxable
yield necessary to produce an after-tax yield equivalent to a Portfolio's tax-
free yield. It is calculated by taking that portion of the seven-day "yield"
which is tax-exempt and adjusting it to reflect the tax savings associated
with a stated tax rate. The "tax-equivalent yield" will always be higher than
the Portfolio's yield.
 
The Portfolios' yields may not provide a basis for comparison with bank
deposits and other investments which provide a fixed yield for a stated period
of time. Yield will be affected by portfolio quality, composition, maturity,
market conditions and the level of the Portfolio's operating expenses.
 
Each Portfolio may also quote from time to time its total return in accordance
with SEC regulations.
 
                                      28
<PAGE>
 
                                  ORGANIZATION
   
Each Portfolio is a series of The Benchmark Funds, which was formed as a
Delaware business trust on July 1, 1997 under an Agreement and Declaration of
Trust. The Portfolios were formerly series of The Benchmark Funds, a
Massachusetts business trust, and were reorganized into the Trust on March 31,
1998. As of the date of this Prospectus, the Trust has created eighteen
separate series of shares of beneficial interest representing interests in
eighteen investment portfolios, four of which are described in this Prospectus;
the other series of shares are described in a separate prospectus. The business
and affairs of the Trust are managed by or under the direction of its Board of
Trustees. The Declaration of Trust of the Trust authorizes the Board of
Trustees to classify or reclassify any unissued shares into additional series
or classes within a series. Pursuant to such authority, the Board of Trustees
has classified three classes of shares in each Portfolio: Service Shares,
Premier Shares and the shares described in this Prospectus. Service Shares and
Premier Shares are described in separate Prospectuses.     
   
Each share of a Portfolio is without par value, represents an equal
proportionate interest in that Portfolio with each other share of its class in
that Portfolio and is entitled to such dividends and distributions earned on
such Portfolio's assets as are declared in the discretion of the Board of
Trustees. Shares of each class bear their pro rata portion of all operating
expenses paid by a Portfolio, except amounts payable under the service plan
that has been adopted for the Portfolios' Service and Premier Share classes and
transfer agency fees. Because of these class-specific expenses, the performance
of the shares of a Portfolio described in this Prospectus is expected to be
higher than the performance of both the Service and Premier Share classes of
the same Portfolio, and the performance of a Portfolio's Service Share class is
expected to be higher than the performance of the same Portfolio's Premier
Share class. For further information regarding the Trust's other share classes,
contact Goldman Sachs at 1-800-621-2550.     
   
The Trust's shareholders are entitled at the discretion of the Board of
Trustees to vote either on the basis of the number of shares held or the
aggregate net asset value represented by such shares. Each series entitled to
vote on a matter will vote thereon in the aggregate and not by series, except
as otherwise required by law or when the matter to be voted on affects only the
interests of shareholders of a particular series. The Additional Statement
gives examples of situations in which the law requires voting by series. Voting
rights are not cumulative and, accordingly, the holders of more than 50% of the
aggregate voting power of the Trust may elect all of the Trustees irrespective
of the vote of the other shareholders. In addition, holders of all shares
(regardless of class) representing interests in the same Portfolio have equal
voting rights except that only shares of a particular class within the
Portfolio will be entitled to vote on matters submitted to a vote of
shareholders (if any) relating to class-specific expenses that are payable by
that class of shares.     
   
As of February 28, 1998, Northern possessed sole or shared voting or investment
power for its customer accounts with respect to more than 50% of the
outstanding shares of the Trust.     
   
The Trust does not presently intend to hold annual meetings of shareholders
except as required by the 1940 Act or other applicable law. The Trustees will
promptly call a meeting of shareholders to vote upon the removal of any Trustee
when so requested in writing by the record holders of 10% or more of the
outstanding shares. To the extent required by law, the Trust will assist in
shareholder communications in connection with such a meeting.     
   
The Trust Agreement provides that each shareholder, by virtue of becoming such,
will be held to have expressly assented and agreed to the terms of the Trust
Agreement and to have become a party thereto.     
 
                                       29
<PAGE>
 
                                 MISCELLANEOUS
 
The address of the Trust is 4900 Sears Tower, Chicago, Illinois 60606 and the
telephone number is 1-800-621-2550.
   
When a shareholder moves, the shareholder is responsible for sending written
notice to the Trust of any new mailing address. The Trust and its transfer
agent may charge a shareholder their reasonable costs in locating a
shareholder's current address in accordance with SEC regulations.     
   
As used in this Prospectus, the term "Business Day" refers to each day when
Northern and the New York Stock Exchange are open, which is Monday through
Friday, except for holidays observed by Northern and/or the Exchange other than
Good Friday. For 1998, the holidays of Northern and/or the Exchange are: New
Year's Day, Dr. Martin Luther King, Jr. Day, Presidents' Day, Memorial Day,
Independence Day, Labor Day, Columbus Day, Veteran's Day, Thanksgiving and
Christmas Day. On those days when Northern or the Exchange closes early as a
result of unusual weather or other circumstances, the Portfolios reserve the
right to advance the time on that day by which purchase, redemption and
exchange requests must be received. In addition, on any Business Day when The
Bond Market Association recommends that the securities markets close or close
early, the Portfolios reserve the right to cease or to advance the deadline for
accepting purchase, redemption and exchange orders for same Business Day
credit. Purchase, redemption and exchange requests received after the advanced
closing time will be effected on the next Business Day. Each Portfolio
reserves, however, the right to reject any purchase order and also to defer
crediting, sending or wiring redemption proceeds for up to seven days after
receiving a redemption order if, in its judgment, an earlier payment would
adversely affect such Portfolio. See "Investing--Purchase of Shares" and
"Investing--Redemption of Shares" above for more information.

                       ADDITIONAL INVESTMENT INFORMATION

Investment Objectives and Policies

The following supplements the investment objectives and policies of the
Government Select, Government, Diversified Assets and Tax-Exempt Portfolios (the
"Portfolios") of The Benchmark Funds (the "Trust") as set forth in the
Prospectus.

Description of Commercial Paper, Bankers' Acceptances, Certificates of Deposit
and Time Deposits

Commercial paper represents short-term unsecured promissory notes issued in
bearer form by banks or bank holding companies, corporations and finance
companies.  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 that
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.

As stated in the Prospectus, the Diversified Assets Portfolio may invest a
portion of its assets in the obligations of foreign banks and foreign branches
of domestic banks.  Such obligations include Eurodollar Certificates of Deposit
("ECDs") which are U.S. dollar-denominated certificates of deposit issued by
offices of foreign and domestic banks located outside the United States;
Eurodollar Time Deposits ("ETDs") which are U.S. dollar-denominated deposits in
a foreign branch of a U.S. bank or a foreign bank; Canadian Time Deposits
("CTDs") which are essentially the same as ETDs except they are issued by
Canadian offices of major Canadian banks; Schedule Bs, which are obligations
issued by Canadian branches of foreign or domestic banks; Yankee Certificates of
Deposit ("Yankee CDs") which are U.S. dollar-denominated certificates of deposit
issued by a U.S. branch of a foreign bank and held in the United States; and
Yankee Bankers' Acceptances ("Yankee BAs") which are U.S. dollar-denominated
bankers' acceptances issued by a U.S. branch of a foreign bank and held in the
United States.

                                      B-3
<PAGE>
 
Description of Asset-Backed Securities
    
The Diversified Assets Portfolio may purchase asset-backed securities, which are
securities backed by mortgages, installment contracts, credit card receivables
or other assets.  The average life of asset-backed securities varies with the
maturities of the underlying instruments, and the average life of a mortgage-
backed instrument, in particular, is likely to be substantially less than the
original maturity of the mortgage pools underlying the securities as a result of
mortgage prepayments.  For this and other reasons, an asset-backed security's
stated maturity may be shortened, and the security's total return may be
difficult to predict precisely.  Such difficulties are not, however, expected to
have a significant effect on the Portfolio since the remaining maturity of any
asset-backed security acquired, as calculated under applicable SEC regulations,
will be 13 months or less.  Asset-backed securities acquired by the Portfolio
may include collateralized mortgage obligations ("CMOs") issued by private
companies.     

U.S. Government Obligations

Examples of the types of U.S. Government obligations that may be acquired by the
Portfolios include U.S. Treasury Bills, Treasury Notes and Treasury Bonds and
the obligations of Federal Home Loan Banks, Federal Farm Credit Banks, Federal
Land Banks, the Federal Housing Administration, Farmers Home Administration,
Export-Import Bank of the United States, Small Business Administration, Federal
National Mortgage Association, Government National Mortgage Association, General
Services Administration, Central Bank for Cooperatives, Federal Home Loan
Mortgage Corporation, Federal Intermediate Credit Banks, and the Maritime
Administration.

Custodial Receipts for Treasury Securities

The Portfolios (other than the Government Select Portfolio) may acquire U.S.
Government obligations and their unmatured interest coupons that have been
separated ("stripped") by their holder, typically a custodian bank or investment
brokerage firm.  Having separated the interest coupons from the underlying
principal of the U.S.  Government obligations, the holder will resell the
stripped securities in custodial receipt programs with a number of different
names, including "Treasury Income Growth Receipts" ("TIGRs") and "Certificate of
Accrual on Treasury Securities" ("CATS").  The stripped coupons are sold
separately from the underlying principal, which is usually sold at a deep
discount because the buyer receives only the right to receive a future fixed
payment on the security and does not receive any rights to periodic interest
(cash) payments.  The underlying U.S. Treasury bonds and notes themselves are
held in book-entry form at the Federal Reserve Bank or, in the case of bearer
securities (i.e., unregistered securities which are ostensibly owned by the
bearer 

                                      B-4
<PAGE>
 
or holder), in trust on behalf of the owners. Counsel to the underwriters of
these certificates or other evidences of ownership of U.S. Treasury securities
have stated that, in their opinion, purchasers of the stripped securities most
likely will be deemed the beneficial holders of the underlying U.S. Government
obligations for Federal tax purposes. The Trust is not aware of any binding
legislative, judicial or administrative authority on this issue.

U.S. Treasury STRIPS

The Treasury Department has facilitated transfers of ownership of zero coupon
securities by accounting separately for the beneficial ownership of particular
interest coupon and principal payments on Treasury securities through the
Federal Reserve book-entry record-keeping system. The Federal Reserve program as
established by the Treasury Department is known as "STRIPS" or "Separate Trading
of Registered Interest and Principal of Securities." Under the STRIPS program, a
Portfolio will be able to have its beneficial ownership of zero coupon
securities recorded directly in the book-entry record-keeping system in lieu of
having to hold certificates or other evidences of ownership of the underlying
U.S. Treasury securities.  All Portfolios, including the Government Select
Portfolio, may acquire securities registered under the STRIPS program.

Bank and Deposit Notes

The Diversified Assets Portfolio may purchase bank and deposit notes.  Bank
notes rank junior to deposit liabilities of banks and pari passu with other
senior, unsecured obligations of the bank. Bank notes are classified as "other
borrowings" on a bank's balance sheet, while deposit notes and certificates of
deposit are classified as deposits. 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.

Variable and Floating Rate Instruments

With respect to the variable and floating rate instruments that may be acquired
by the Portfolios as described in the Prospectus, Northern will consider the
earning power, cash flows and other liquidity ratios of the issuers and
guarantors of such instruments and, if the instruments are subject to demand
features, will monitor their financial status and ability to meet payment on
demand.  Where necessary to ensure that a variable or floating rate instrument
is of "high quality," the issuer's obligation to pay the principal of the
instrument will be backed by an unconditional bank letter or line of credit,
guarantee or commitment to lend.  The Portfolios will invest in variable and
floating rate instruments only when Northern deems the investment to involve

                                      B-5
<PAGE>
 
minimal credit risk. In determining weighted average portfolio maturity, an
instrument may, subject to SEC regulations, be deemed to have a maturity shorter
than its nominal maturity based on the period remaining until the next interest
rate adjustment or the time the Portfolio involved can recover payment of
principal as specified in the instrument.

Investment Companies
    
With respect to the investments of the Portfolios in the securities of other
investment companies, such investments will be limited so that, as determined
after a purchase is made, either (a) not more that 3% of the total outstanding
stock of such investment company will be owned by a Portfolio, the Trust as a
whole and their affiliated persons (as defined in the 1940 Act); or (b)(i) not
more that 5% of the value of the total assets of a Portfolio will be invested in
the securities of any one investment company, (ii) not more that 10% of the
value of its total assets will be invested in the aggregate in securities of
investment companies as a group, and (iii) not more that 3% of the outstanding
voting stock of any one investment company will be owned by the Portfolio. 

Unaffiliated money market funds whose securities are purchased by the Portfolios
may not be obligated to redeem such securities in an amount exceeding 1% of
their total outstanding securities during any period of less than 30 days.
Therefore, such securities that exceed this amount may be illiquid.

If required by the 1940 Act, each Portfolio expects to vote the shares of other
investment companies that are held by it in the same proportion as the vote of
all other holders of such securities.

A Portfolio may invest all or substantially all of its assets in a single open-
end investment company or series thereof with substantially the same investment
objective, policies and restrictions as the Portfolio. However, each Portfolio
currently intends to limit its investments in securities issued by other
investment companies to the extent described above. A Portfolio may adhere to
more restrictive limitations with respect to its investments in securities
issued by other investment companies if required by the SEC or deemed to be in
the best interests of the Trust.     

Repurchase Agreements

Each Portfolio may enter into repurchase agreements with financial institutions,
such as banks and broker-dealers, as are deemed creditworthy by Northern under
guidelines approved by the Trust's Board of Trustees.  The repurchase price
under the repurchase agreements will generally equal the price paid by a
Portfolio plus interest negotiated on the basis of current 

                                      B-6
<PAGE>
 
short-term rates (which may be more or less than the rate on the securities
underlying the repurchase agreement). Securities subject to repurchase
agreements will be held by the Trust's custodian (or subcustodian), in the
Federal Reserve/Treasury book-entry system or by another authorized securities
depository. Repurchase agreements are considered to be loans by a Portfolio
under the 1940 Act.

Reverse Repurchase Agreements

Each Portfolio (except the Tax-Exempt Portfolio) may borrow funds for temporary
or emergency purposes by selling portfolio securities to financial institutions
such as banks and broker/dealers and agreeing to repurchase them at a mutually
specified date and price ("reverse repurchase agreements"). Reverse repurchase
agreements involve the risk that the market value of the securities sold by a
Portfolio may decline below the repurchase price. The Portfolios will pay
interest on amounts obtained pursuant to a reverse repurchase agreement. While
reverse repurchase agreements are outstanding, a Portfolio will segregated
liquid assets in an amount at least equal to the market value of the securities,
plus accrued interest, subject to the agreement. Reverse repurchase agreements
are considered to be borrowings by a Portfolio under the 1940 Act.

Securities Lending

Collateral for loans of portfolio securities made by a Portfolio may consist of
cash, securities issued or guaranteed by the U.S. Government or its agencies or
irrevocable bank letters of credit (or any combination thereof).  The borrower
of securities will be required to maintain the market value of the collateral at
not less than the market value of the loaned securities, and such value will be
monitored on a daily basis.  When a Portfolio lends its securities, it continues
to receive interest on the securities loaned and may simultaneously earn
interest on the investment of the cash collateral which will be invested in
readily marketable, high-quality, short-term obligations.  Although voting
rights, or rights to consent, attendant to securities on loan pass to the
borrower, such loans will be called so that the securities may be voted by a
Portfolio if a material event affecting the investment is to occur.

Forward Commitments and When-Issued Securities

Each Portfolio may purchase securities on a when-issued basis or purchase or
sell securities on a forward commitment (sometimes called delayed delivery)
basis.  These transactions involve a commitment by the Portfolio 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 

                                      B-7
<PAGE>
 
and forward commitment transactions are normally negotiated directly with the
other party.

A Portfolio 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 Portfolio may dispose
of or negotiate a commitment after entering into it. A Portfolio also may sell
securities it has committed to purchase before those securities are delivered to
the Portfolio on the settlement date. The Portfolio may realize a capital gain
or loss in connection with these transactions. For purposes of determining a
Portfolio's average dollar-weighted maturity, the maturity of when-issued or
forward commitment securities will be calculated from the commitment date.
    
When a Portfolio purchases securities on a when-issued or forward commitment
basis, the Portfolio will separate liquid assets having a value (determined
daily) at least equal to the amount of the Portfolio's purchase commitments.  In
the case of a forward commitment to sell portfolio securities, the portfolio
will separate the portfolio securities themselves.  These procedures are
designed to ensure that the Portfolio will maintain sufficient assets at all
times to cover its obligations under when-issued purchases and forward
commitments.     

Yields and Ratings

The yields on certain obligations, including the money market instruments in
which the Portfolios invest (such as commercial paper and bank obligations), are
dependent on a variety of factors, including general money market conditions,
conditions in the particular market for the obligation, financial condition of
the issuer, size of the offering, maturity of the obligation and ratings of the
issue.  The ratings of S&P, Moody's, D&P, Fitch and TBW represent their
respective opinions as to the quality of the obligations they undertake to rate.
Ratings, however, are general and are not absolute standards of quality.
Consequently, obligations with the same rating, maturity and interest rate may
have different market prices.

Municipal Instruments

Opinions relating to the validity of Municipal Instruments and to the exemption
of interest thereon from regular Federal income tax are rendered by bond counsel
to the respective issuing authorities at the time of issuance.  Neither the
Trust nor Northern will review the proceedings relating to the issuance of
Municipal Instruments or the bases for such opinions.

An issuer's obligations under its Municipal Instruments are subject to the
provisions of bankruptcy, insolvency and other 

                                      B-8
<PAGE>
 
laws affecting the rights and remedies of creditors, such as the Federal
Bankruptcy Code, and laws, if any, which may be enacted by Federal or state
legislatures extending the time for payment of principal or interest, or both,
or imposing other constraints upon enforcement of such obligations or upon the
ability of municipalities to levy taxes. The power or ability of an issuer to
meet its obligations for the payment of interest on and principal of its
Municipal Instruments may be materially adversely affected by litigation or
other conditions.

From time to time proposals have been introduced before Congress for the purpose
of restricting or eliminating the Federal income tax exemption for interest on
Municipal Instruments.  For example, under the Tax Reform Act of 1986 interest
on certain private activity bonds must be included in an investor's Federal
alternative minimum taxable income, and corporate investors must include all
tax-exempt interest in their Federal alternative minimum taxable income.  The
Trust cannot predict what legislation, if any, may be proposed in the future in
Congress as regards the Federal income tax status of interest on Municipal
Instruments. Future proposals could materially adversely affect the availability
of Municipal Instruments for investment by the Tax-Exempt Portfolio and the
liquidity and value of the Portfolio.  In such an event the Board of Trustees
would reevaluate the Portfolio's investment objective and policies and consider
changes in its structure or possible dissolution.

Interest earned by the Tax-Exempt Portfolio on private activity bonds (if any)
that is treated as a specific tax preference item under the Federal alternative
minimum tax will not be deemed to have been derived from Municipal Instruments
for purposes of determining whether that Portfolio meets its fundamental policy
that at least 80% of its annual gross income be derived from Municipal
Instruments.

Standby Commitments

The Tax-Exempt Portfolio may enter into standby commitments with respect to
Municipal Instruments held by it.  Under a standby commitment, a dealer agrees
to purchase at the Portfolio's option a specified Municipal Instrument at its
amortized cost value to the Portfolio plus accrued interest, if any.  Standby
commitments may be exercisable by the Portfolio at any time before the maturity
of the underlying Municipal Instruments and may be sold, transferred or assigned
only with the instruments involved.

The Tax-Exempt Portfolio expects that standby commitments will generally be
available without the payment of any direct or indirect consideration. However,
if necessary or advisable, the Portfolio may pay for a standby commitment either
separately in cash or by paying a higher price for Municipal Instruments which
are acquired subject to the commitment (thus reducing the yield to maturity
otherwise available for the same securities).  The 

                                      B-9
<PAGE>
 
total amount paid in either manner for outstanding standby commitments held by
the Portfolio will not exceed 1/2 of 1% of the value of the Portfolio's total
assets calculated immediately after each standby commitment is acquired.

The Portfolio intends to enter into standby commitments only with dealers, banks
and broker-dealers which, in Northern's opinion, present minimal credit risks.
The Portfolio will acquire standby commitments solely to facilitate portfolio
liquidity and does not intend to exercise its rights thereunder for trading
purposes. The acquisition of a standby commitment will not affect the valuation
or assumed maturity of the underlying Municipal Instrument. The actual standby
commitment will be valued at zero in determining net asset value. Accordingly,
where the Portfolio pays directly or indirectly for a standby commitment, its
cost will be reflected as an unrealized loss for the period during which the
commitment is held by the Portfolio and will be reflected in realized gain or
loss when the commitment is exercised or expires.

Investment Restrictions

Each Portfolio is subject to the fundamental investment restrictions enumerated
below which may be changed with respect to a particular Portfolio only by a vote
of the holders of a majority of such Portfolio's outstanding shares.

No Portfolio may:
    
     (1)  Make loans, except (a) through the purchase of debt obligations in
     accordance with the Portfolio's investment objective and policies, (b)
     through repurchase agreements with banks, brokers, dealers and other
     financial institutions, and (c) loans of securities.

     (2)  Mortgage, pledge or hypothecate any assets (other than pursuant to
     reverse repurchase agreements for the Diversified Assets, Government and
     Government Select Portfolios) except to secure permitted borrowings.

     (3)  Purchase or sell real estate or securities issued by real estate
     investment trusts, but this restriction shall not prevent a Portfolio from
     investing directly or indirectly in portfolio instruments secured by real
     estate or interests therein.

     (4)  Purchase or sell commodities or commodity contracts or oil or gas or
     other mineral exploration or development programs.

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

                                     B-10
<PAGE>
 
     (6)  Act as underwriter of securities (except as a Portfolio may be deemed
     to be an underwriter under the Securities Act of 1933 in connection with
     the purchase and sale of portfolio instruments in accordance with its
     investment objective and portfolio management policies), 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 or maintain a short
     position, or write puts, calls or combinations thereof.

     (7)  Make any investment inconsistent with the Portfolio's classification
     as a diversified investment company under the 1940 Act.

     (8)  Purchase securities if such purchase would cause more than 25% in the
     aggregate of the market value of the total assets of a Portfolio 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 Portfolio 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 foreign banks and
     repurchase agreements and securities loans collateralized by such U.S.
     Government obligations 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; as to utility companies, the
     gas, electric, water and telephone businesses are considered separate
     industries; 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 industries of their parents if their
     activities are primarily related to financing the activities of their
     parents.

     (9)  Borrow money (other than pursuant to reverse repurchase agreements for
     the Portfolios described above), except (a) as a temporary measure, and
     then only in amounts not exceeding 5% of the value of the Portfolio's total
     assets or (b) from banks, provided that immediately after any such
     borrowing all borrowings of the Portfolio do not exceed one-third of the
     Portfolio's total assets. No purchases of securities will be made if
     borrowings subject to this restriction exceed 5% of the value of the
     Portfolio's assets. The exceptions in (a) and (b) to this restriction are
     not for investment leverage purposes but are solely for extraordinary or
     emergency purposes or to facilitate management of the Trust's Portfolios by
     enabling the Trust to meet redemption requests when the liquidation

                                     B-11
<PAGE>
 
     of portfolio instruments is deemed to be disadvantageous or not possible.
     If due to market fluctuations or other reasons the total assets of a
     Portfolio fall below 300% of its borrowings, the Trust will promptly reduce
     the borrowings of such Portfolio in accordance with the 1940 Act.

     (10)  Notwithstanding any of the Trust's other fundamental investment
     restrictions (including, without limitation, those restrictions relating to
     issuer diversification, industry concentration and control), each Portfolio
     may (a) purchase securities of other investment companies to the full
     extent permitted under Section 12 of the 1940 Act (or any successor
     provision thereto) or under any regulation or order of the Securities and
     Exchange Commission; and (b) invest all or substantially all of its assets
     in a single open-end investment company or series thereof with
     substantially the same investment objective, policies and fundamental
     restrictions as the Portfolio.

The freedom of action reserved in Restriction No. 98 with respect to U.S.
branches of foreign banks is subject to the requirement that they are subject to
the same regulation as domestic branches of U.S. banks.  Obligations of U.S.
branches of foreign banks may include certificates of deposit, bank and deposit
notes, bankers' acceptances and fixed time deposits any may be signed
obligations of the parent bank or may be limited to the issuing branches.  Such
obligations will meet the criteria for "Eligible Securities" as described in the
Prospectus.     

In addition, as matters of fundamental policy, the Government Select Portfolio,
Government Portfolio and Diversified Assets Portfolio may not enter into reverse
repurchase agreements exceeding in the aggregate one-third of the applicable
Portfolio's total assets; and the Tax-Exempt Portfolio may not acquire direct
ownership of industrial development bonds if, as a result of such acquisition,
more than 5% of the value of its total assets would be invested in industrial
development bonds where payment of principal and interest is the responsibility
of companies (including their predecessors) with less than three years of
operating history and such bonds are not guaranteed as to principal and interest
by companies (including their predecessors) with three years or more of
operating history.
    
Except to the extent otherwise provided in Investment Restriction No. 8, for the
purpose of such restriction in determining industry classification the Trust
intends to use the industry classification titles in the Standard Industrial
Classification Manual.     

                                     B-12

In applying Restriction No. 8 above, a security is considered to be issued by
the entity, or entities, whose assets and revenues back the security.  A
guarantee of a security is not deemed to be a security issued by the guarantor
when the value of all securities issued and guaranteed by the guarantor, and
owned by a Portfolio, does not exceed 10% of the value of the Portfolio's total
assets.

Any restriction which involves a maximum percentage will 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.

    
The Portfolios intend, as a non-fundamental policy, to diversify their
investments in accordance with current SEC regulations. Investments in the
securities of any single issuer (excluding cash, cash items, certain repurchase
agreements, U.S. Government securities and securities of other investment
companies) will be limited to not more than 5% of the value of a Portfolio's
total assets at the time of purchase, except that 25% of the value of the total
assets of each Portfolio may be invested in the securities of any one issuer for
a period of up to three Business Days. A security that has an unconditional
guarantee meeting special SEC requirements (a "Guarantee") does not need to
satisfy the foregoing issuer diversification requirements that would otherwise
apply, but the Guarantee is instead subject to the following diversification
requirements: Immediately after the acquisition of the security, a Portfolio may
not have invested more that 10% of its total assets in securities issued by or
subject to Guarantees from the same person, except that a Fund my , subject to
certain conditions, invest up to 25% of its total assets in securities issued or
subject to Guarantees of the same person. This percentage is 100% if the
Guarantee is issued by the U.S. Government or an agency thereof. In additional,
the Tax-Exempt Portfolio will limit its investments in certain conduit
securities that are not rated in the highest short-term rating category as
determined by two NRSROs (or one NRSRO if the security is rated by only one
NRSRO) or, if unrated, are not of comparable quality ("Second Tier Securities"),
to 5% of its total assets, with investments in any one such issuer being limited
to no more that 1% of the Portfolio's total assets or $1 million, whichever is
greater, measured at the time of purchase. Conduit securities subject to this
limitation are Municipal Instruments that are not subject to a Guarantee and
involve an arrangement whereunder a person, other that a municipal issuer,
provides for or secures repayment of the security and are not: (i) fully and
unconditionally guaranteed by a municipal issuer; or (ii) payable from the
general revenues of the municipal issuer or other municipal issuers; or (iii)
related to a project owned and operated by a municipal issuer; or (iv) related
to a facility leased to and under the control of an industrial or commercial
enterprise that is part of a public project which, as a whole, is owned and
     

                                     B-13
<PAGE>

     
under the control of a municipal issuer.  The Diversified Assets Portfolios will
limit its investments in all Second Tier Securities (that are not subject to a
Guarantee) in accordance with the foregoing percentage limitations.

In addition to the foregoing, each Portfolio is subject to additional
diversification requirements imposed by SEC regulations on the acquisition of
securities subject to other types of demand features and puts whereunder a
Portfolio has the right to sell the securities to third parties.

Certain of the Trustees and officers and the organizations with which they are
associated have had in the past, and may have in the future, transactions with
Northern, Goldman Sachs and their respective affiliates. The Trust has been
advised by such Trustees and officers that all such transactions have been and
are expected to be in the ordinary course of business and the terms of such
transactions, including all loans and loan commitments by such persons, have
been and are expected to be substantially the same as the prevailing terms for
comparable transactions for other customers. Messrs. Springer, Kelsey, Strubel,
Mosior, Gilman, Richman, Surloff and Hartstein and Mmes. Farrell, Mucker and
Zondorak hold similar positions with one or more investment companies that are
advised by Goldman Sachs. As a result of the responsibilities assumed by
Northern under its Advisory Agreement, Transfer Agency Agreement and Custodian
Agreement and Foreign Custody Agreement with the Trust and

                                      B-18
<PAGE>
 
by Goldman Sachs under its Administration Agreement and Distribution Agreement
with the Trust, the Trust itself requires no employees.

Each officer holds comparable positions with certain other investment companies
of which Goldman Sachs, GSAM or an affiliate thereof is the investment adviser,
administrator and/or distributor.

Each Trustee earns a quarterly retainer of $6,250 and the Chairman of the Board
earns a quarterly retainer of $9,375. Each Trustee, including the Chairman of
the Board, earns an additional fee of $1,500 for each meeting attended, plus
reimbursement of expenses incurred as a Trustee.

In addition, the Trustees established an Audit Committee consisting of three
members including a Chairman of the Committee. Each member earns a fee of $1,500
for each meeting attended and the Chairman earns a quarterly retainer of $1,250.

Each Trustee will hold office for an indefinite term until the earliest of (1)
the next meeting of shareholders if any, called for the purpose of considering
the election or re-election of such Trustee and until the election and
qualification of his or her successor, if any, elected at such meeting; (2) the
date a Trustee resigns or retires, or a Trustee is removed by the Board of
Trustees or shareholders, in accordance with the Trust's Agreement and
Declaration of Trust, or (3) in accordance with the current resolutions of the
Board of Trustees (which may be changed without shareholder vote), on the last
day of the fiscal year of the Trust in which he or she attains the age of 72
years.

The Trust's officers do not receive fees from the Trust for services in such
capacities, although Goldman Sachs, of which they are also officers, receives
fees from the Trust for administrative services.

Investment Adviser, Transfer Agent and Custodian
    
Northern, a wholly-owned subsidiary of Northern Trust Corporation, a bank
holding company, is one of the nation's leading providers of trust and
investment management services. As of December 31, 1997, Northern and its
affiliates had over $196 billion in assets under management for clients
including public and private retirement funds, endowments, foundations, trusts,
corporations, and individuals. Northern is one of the strongest banking
organizations in the United States. Northern believes it has built its
organization by serving clients with integrity, a commitment to quality, and
personal attention. Its stated mission with respect to all its financial
products and services is to achieve unrivaled client satisfaction. With respect
to such clients, the Trust is designed to assist (i) defined contribution plan
sponsors and their employees by offering a range of diverse investment options
to help comply with 404(c) regulation and may also provide educational material
to their employees, (ii) employers who provide post-retirement Employees'
Beneficiary Associations ("VEBA") and require investments that respond to the
impact of federal regulations, (iii) insurance companies with the day-to-day
management of uninvested cash balances as well as with longer-term investment
needs, and (iv) charitable and not-for-profit organizations, such as endowments
and foundations, demanding investment management solutions that balance the
requirement for sufficient current income to meet operating expenses and the
need for capital appreciation to meet future investment objectives.

Under its Advisory Agreement with the Trust, Northern, subject to the general
supervision of the Trust's Board of Trustees, is responsible for making
investment decisions for each Portfolio and placing purchase and sale orders for
the portfolio transactions of the Portfolios. In connection with portfolio
transactions for the Portfolios, which are generally done at a net price without
a broker's commission, Northern's Advisory Agreement provides that Northern
shall attempt to obtain the best net price and execution. To the extent the
execution and price available from more than one broker, dealer or other such
persons are believed to be comparable, Northern may, at its discretion but
suject to applicable law, select the executing broker, dealer or such other
persons on the basis of Northern's opinion of the reliability and quality of
such broker, dealer or such other persons.     

For the fiscal years ended November 30, 1997, 1996 and 1995, all portfolio
Transactions for the Portfolios were executed on a principal basis and,
therefore, no brokerage commissions were paid by the Portfolios.  Purchases by
the Portfolios from underwriters of portfolio securities, however, normally
include a commission or concession paid by the issuer to the underwriter, and
purchases from dealers include the spread between the 

                                     B-21
<PAGE>
 
dealer's cost for a given security and the resale price of the security.

Northern's investment advisory duties for the Trust are carried out through its
Trust Department.  On occasions when Northern deems the purchase or sale of a
security to be in the best interests of a Portfolio as well as other fiduciary
or agency accounts managed by it (including any other Portfolio, investment
company or account for which Northern acts as adviser), the Agreement provides
that Northern, to the extent permitted by applicable laws and regulations, may
aggregate the securities to be sold or purchased for such Portfolio with those
to be sold or purchased for such other accounts in order to obtain best net
price and execution.  In such event, allocation of the securities so purchased
or sold, as well as the expenses incurred in the transaction, will be made by
Northern in the manner it considers to be most equitable and consistent with its
fiduciary obligations to the Portfolio and other accounts involved.  In some
instances, this procedure may adversely affect the size of the position
obtainable for a Portfolio or the amount of the securities that are able to be
sold for a Portfolio.  To the extent that the execution and price available from
more than one broker or dealer are believed to be comparable, the Agreement
permits Northern, at its discretion but subject to applicable law, to select the
executing broker or dealer on the basis of Northern's opinion of the reliability
and quality of such broker or dealer.

The Advisory Agreement provides that Northern may render similar services to
others so long as its services under such Agreement are not impaired thereby.
The Advisory Agreement also provides that the Trust will indemnify Northern
against certain liabilities (including liabilities under the Federal securities
laws relating to untrue statements or omissions of material fact and actions
that are in accordance with the terms of the Agreement) or, in lieu thereof,
contribute to resulting losses.

Under its Transfer Agency Agreement with the Trust, Northern has undertaken to
(1) answer customer inquiries regarding the current yield of, and certain other
matters (e.g. account status information) pertaining to, the Trust, (2) process
purchase and redemption transactions, including transactions generated by any
service provided outside of the Agreement by Northern, its affiliates or
correspondent banks whereby customer account cash balances are automatically
invested in shares of the Portfolios, and the disbursement of the proceeds of
redemptions, (3) establish and maintain separate omnibus accounts with respect
to shareholders investing through Northern or any of its affiliates and
correspondent banks and act as transfer agent and perform sub-accounting
services with respect to each such account, (4) provide periodic statements
showing account balances, (5) mail reports and proxy materials to shareholders,
(6) provide information in connection with the preparation by the Trust of
various regulatory reports and prepare reports to the Trustees and management,
(7) answer inquiries (including requests for

                                     B-22
<PAGE>
     
prospectuses and statements of additional information, and assistance in the
completion of new account applications) from investors and respond to all
requests for information regarding the Trust (such as current price, recent
performance, and yield data) and questions relating to accounts of investors
(such as possible errors in statements, and transactions), (8) respond to and
seek to resolve all complaints of investors with respect to the Trust or their
accounts, (9) furnish proxy statements and proxies, annual and semi-annual
financial statements, and dividend, distribution and tax notices to investors,
(10) furnish the Trust all pertinent Blue Sky information, (11) perform all
required tax withholding, (12) preserve records, and (13) furnish necessary
office space, facilities and personnel. Northern may appoint one or more sub-
transfer agents in the performance of its services.

As compensation for the services rendered by Northern under the Transfer Agency
Agreement with respect to the Shares described in this Additional Statement and
the assumption by Northern of related expenses, Northern is entitled to a fee
from the Trust, payable monthly, at an annual rate equal to $18 for each
subaccount relating to such shares of the Portfolios. This fee which is borne
solely by the Shares described in this Additional Statement and not by the
Portfolios' other share classes, is subject to annual upward adjustments based
on increases in the Consumer Price Index for All Urban Consumers, provided that
Northern may permanently or temporarily waive all or any portion of any upward
adjustment. Northern's affiliates and correspondent banks may receive
compensation for performing the services described in the preceding paragraph
that Northern would otherwise receive. Conflict-of-interest restrictions under
state and Federal law (including the Employee Retirement Income Security Act of
1974) may apply to the receipt by such affiliates or correspondent banks of such
compensation in connection with the investment of fiduciary funds in Shares of
the Portfolios.

Under its Custodian Agreement with the Trust, Northern (1) holds each
Portfolio's cash and securities, (2) maintains such cash and securities in
separate accounts in the name of the Portfolio, (3) makes receipts and
disbursements of funds on behalf of the Portfolio, (4) receives, delivers and
releases securities on behalf of the Portfolio, (5) collects and receives all
income, principal and other payments in respect of the Portfolio's securities
held by Northern under the Agreement, and (6) maintains the accounting records
of the Trust. Northern may employ one or more subcustodians, provided that
Northern shall, subject to certain monitoring responsibilities, have no more
responsibility or liability to the Trust on account of any action or omission of
any subcustodian so employed than such subcustodian has to Northern and that the
responsibility or liability of the subcustodian to Northern shall conform to the
resolution of the Trustees of the Trust authorizing the appointment of the
particular subcustodian. Northern may also appoint agents to carry out such of
the provisions of the     

                                     B-23
<PAGE>
 
Custodian Agreement as Northern may from time to time direct, provided that the
appointment of an agent shall not relieve Northern of any of its
responsibilities under the Agreement.

As compensation for the services rendered to the Trust by Northern as custodian,
and the assumption by Northern of certain related expenses, Northern is entitled
to payment from the Trust as follows: (i) $18,000 annually for each Portfolio,
plus (ii) 1/100th of 1% annually of each Portfolio's average daily net assets to
the extent they exceed $100 million, plus (iii) a fixed dollar fee for each
trade in portfolio securities, plus (iv) a fixed dollar fee for each time that
Northern as custodian receives or transmits funds via wire, plus (v)
reimbursement of expenses incurred by Northern as custodian for telephone,
postage, courier fees, office supplies and duplicating. The fees referred to in
clauses (iii) and (iv) are subject to annual upward adjustments based on
increases in the Consumer Price Index for All Urban Consumers, provided that
Northern may permanently or temporarily waive all or any portion of any upward
adjustment.
    
Northern's fees under the Custodian Agreement are subject to reduction based on
the Portfolios' daily uninvested cash balances.     

Unless sooner terminated, each of the Advisory Agreement, Transfer Agency
Agreement and Custodian Agreement between Northern and the Trust will continue
in effect with respect to a particular Portfolio until April 30, 1999, and
thereafter for successive 12-month periods, provided that the continuance is
approved at least annually (1) by the vote of a majority of the Trustees who are
not parties to the agreement or "interested persons" (as such term is defined in
the 1940 Act) of any party thereto, cast in person at a meeting called for the
purpose of voting on such approval and (2) by the Trustees or by the vote of a
majority of the outstanding shares of such Portfolio (as defined below under
"Other Information"). Each agreement is terminable at any time without penalty
by the Trust (by specified Trustee or shareholder action) on 60 days' written
notice to Northern and by Northern on 60 days' written notice to the Trust.

For the fiscal periods ended November 30 as indicated, the amount of the
Advisory Fee (after fee waivers) incurred by each Portfolio was as follows:

Banking laws and regulations currently prohibit a bank holding company
registered under the Federal Bank Holding Company Act of 1956 or any bank or 
non-bank affiliate thereof from sponsoring, organizing, controlling or
distributing the shares of a registered open-end investment company continuously
engaged in the issuance of its shares, but such banking laws and regulations do
not prohibit such a holding company or affiliate or banks generally from acting
as investment adviser, transfer agent or custodian to such an investment
company, or from purchasing shares of such a company as agent for and upon the
order of customers. Northern believes that it may perform the services
contemplated by its agreements with the Trust without violation of such banking
laws or regulations, which are applicable to it. It should be noted, however,
that future changes in either Federal or state statutes and regulations relating
to the permissible activities of banks and their subsidiaries or affiliates, as
well as future judicial or administrative decisions or interpretations of
current and future statutes and regulations, could prevent Northern from
continuing to perform such services for the Trust.

Should future legislative, judicial or administrative action prohibit or
restrict the activities of Northern in connection with the provision of services
on behalf of the Trust, the Trust might be required to alter materially or
discontinue its arrange ments with Northern and change its method of operations.
It is not anticipated, however, that any change in the Trust's method of
operations would affect the net asset value per share of any Portfolio or result
in a financial loss to any shareholder. Moreover, if current restrictions
preventing a bank from legally sponsoring, organizing, controlling or
distributing shares of an

                                     B-25
<PAGE>
     
open-end investment company were relaxed, the Trust expects that Northern and
its affiliates would consider the possibility of offering to perform some or all
of the services now provided by Goldman Sachs. It is not possible, of course, to
predict whether or in what form such restrictions might be relaxed or the terms
upon which Northern as its affiliates might offer to provide services for
consideration by the Trustees.     

Northern is active as an underwriter of municipal instruments. Under the 1940
Act the Portfolios are precluded, subject to certain exceptions, from purchasing
in the primary market those municipal instruments with respect to which Northern
is serving as a principal underwriter. In the opinion of Northern, this
limitation will not significantly affect the ability of the Portfolios to pursue
their respective investment objectives.

Goldman Sachs is also an active investor, dealer and/or underwriter in many
types of money market instruments. Its activities in this regard could have some
effect on the market for those instruments which the Portfolios acquire, hold or
sell.

In the Advisory Agreement, Northern agrees that the name "The Benchmark" may be
used in connection with the Trust's business on a royalty-free basis. Northern
has reserved to itself the right to grant the non-exclusive right to use the
name "The Benchmark" to any other person. The Advisory Agreement provides that
at such time as the Agreement is no longer in effect, the Trust will cease using
the name "The Benchmark." (This undertaking by the Trust may be subject to
certain legal limitations.)

Administrator and Distributor
    
Under its Administration Agreement with the Trust, Goldman Sachs, subject to the
general supervision of the Trust's Board of Trustees, acts as the Trust's
Administrator.  In this capacity, Goldman Sachs (1) provides supervision of all
aspects of the Trust's non-investment advisory operations (the parties giving
due recognition to the fact that certain of such operations are performed by
Northern pursuant to the Trust's agreements with Northern), (2) provides the
Trust, to the extent not provided pursuant to such agreements, with such
personnel as are reasonably necessary for the conduct of the Trust's affairs,
(3) arranges, to the extent not provided pursuant to such agreements, for the
preparation at the Trust's expense of its tax returns, reports to shareholders,
periodic updating of the prospectuses issued by the Trust, and reports filed

state securities or Blue Sky laws of the Trust's shares), and (4) provides the
Trust, to the extent not provided pursuant to such agreements, with adequate
office space and equipment and certain related services in Chicago.     

For the fiscal periods ended November 30 as indicated, Goldman Sachs received
fees under the Administration Agreement (after fee waivers) in the amount of:

In addition, pursuant to an undertaking that commenced August 1, 1992, Goldman
Sachs agreed that, if its administration fees (less expense reimbursements paid
by Goldman Sachs to the Trust and less certain marketing expenses paid by
Goldman Sachs) exceed a specified amount ($1 million for the Trust's first
twelve investment portfolios plus $50,000 for each additional portfolio) during
the current fiscal year, Goldman Sachs will waive a portion of its
administration fees during the following fiscal year. This undertaking may be
terminated by Goldman Sachs at any time without the consent of the Trust or the
shareholders. There have been no waivers pursuant to this agreement during the
last three fiscal periods.

Goldman Sachs has agreed for the current fiscal year to reimburse each Portfolio
for the sum of the Portfolio expenses (including fees payable to Goldman Sachs
as administrator, but excluding the fees payable to Northern for its duties as
investment adviser and transfer agent, payments under the service plans for the
Portfolios' Service and ________ share charges, and extraordinary expenses)
which exceed on an annualized basis .10% of each Portfolio's average daily net
assets. Prior to May 1, 1997, this undertaking was voluntary with respect to the
Portfolios. As of May 1, 1997, this undertaking is contractual with respect to
all Portfolios.

Effective April 1, 1998, (upon the offering of the Service and Premier Shares),
Goldman Sachs will reimburse "other expenses" of each Portfolio (including fees
payable to Goldman Sachs as administrator, but excluding the fees payable to
Northern for its duties as adviser and transfer agent, payments under the
service plans for Services and Premier Shares and certain extraordinary
expenses) exceeds on an annualized basis .10% of each Portfolio's average daily
net assets.

For the fiscal periods ended November 30 as indicated, and prior to May 1, 1997,
[Goldman Sachs voluntarily agreed to waive a portion of its Administration Fee
for each Portfolio resulting in an effective fee of .10% of the average daily
net assets for each Portfolio.] The effect of these waivers by Goldman Sachs was
to reduce other expenses by the following amounts:

Unless sooner terminated, the Administration Agreement will continue in effect
with respect to a particular Portfolio until April 30, 1999, and thereafter for
successive 12-month periods, provided that the agreement is approved annually
(1) by the vote of a majority of the Trustees who are not parties to the
agreement or "interested persons" (as such term is defined by the 1940 Act) of
any party thereto, cast in person at a meeting called for the purpose of voting
on such approval, and (2) by the Trustees or by the vote of a majority of the
outstanding shares of such Portfolio (as defined below under "Other
Information"). The Administration Agreement is terminable at any time without

penalty by the Trust (upon specified Trustee or shareholder action) on 60 days'
written notice to Goldman Sachs and by Goldman Sachs on 60 days' written notice
to the Trust.

The Trust has entered into a Distribution Agreement under which Goldman Sachs,
as agent, sells shares of each Portfolio on a continuous basis. Goldman Sachs
pays the cost of printing and distributing prospectuses to persons who are not
shareholders of Trust shares (excluding preparation and typesetting expenses)
and of all other sales presentations, mailings, advertising and other
distribution efforts. No compensation is payable by the Trust to Goldman Sachs
for such distribution services.

The Administration Agreement and the Distribution Agreement provide that Goldman
Sachs may render similar services to others so long as its services under such
Agreements are not impaired thereby. The Administration Agreement provides that
the Trust will indemnify Goldman Sachs against certain liabilities (including
liabilities under the Federal securities laws relating to untrue statements or
omissions of material fact and actions that are in accordance with the terms of
the Administration Agreement and Distribution Agreement) or, in lieu thereof,
contribute to resulting losses.

Counsel and Auditors

Drinker Biddle & Reath LLP, with offices at 1345 Chestnut Street, Suite 1100,
Philadelphia, Pennsylvania 19107, serve as counsel to the Trust.

Ernst & Young LLP, independent auditors, 233 S. Wacker Drive, Chicago, Illinois
60606, have been selected as auditors of the Trust. In addition to audit
services, Ernst & Young LLP prepares the Trust's Federal and state tax returns,
and provides consultation and assistance on accounting, internal control and
related matters.

In-Kind Purchases

Payment for shares of a Portfolio may, in the discretion of Northern, be made in
the form of securities that are permissible investments for the Portfolio as
described in the Prospectus. For further information about this form of payment,
contact Northern. In connection with an in-kind securities payment, a Portfolio
will require, among other things, that the securities be valued on the day of
purchase in accordance with the pricing methods used by the Portfolio and that
the Portfolio receive satisfactory assurances that it will have good and
marketable title to the securities received by it; that the securities be in
proper form for transfer to the Portfolio; and that adequate information be
provided concerning the basis and other tax matters relating to the securities.

                            PERFORMANCE INFORMATION

    
From time to time the Trust may advertise quotations of "yields" and "effective
yields" with respect to each Portfolio's Shares, and "tax-equivalent yields"
with respect to Shares of the Government Select Portfolio and Tax-Exempt
Portfolio computed in accordance with a standardized method, based upon the
seven-day period ended on the date of calculation. In arriving at such
quotations as to "yield," the Trust first determines the net change during the
period in the value of a hypothetical pre-existing account having a balance of
one Share at the beginning of the period (such net change being inclusive of the
value of any additional Shares issued in connection with distributions of net
investment income as well as net investment income accrued on both the original
Share and any such additional Shares, but exclusive of realized gains and losses
from the sale of securities and unrealized appreciation and depreciation), then
divides such net change by the value of the account at the beginning of the
period to obtain the base period return, and then multiplies the base period
return by 365/7.

The "effective yield" with respect to the Shares of a Portfolio is computed by
adding 1 to the base period return (calculated as above), raising the sum to a
power equal to 365 divided by 7, and subtracting 1 from the result.

"Tax-equivalent yield" is computed by dividing the tax-exempt portion of the
yield by 1 minus a stated income tax rate, and then adding the product to the
taxable portion of the yield, if any. There may be more than one tax-equivalent
yield, if more than one stated income tax rate is used.

Quotations of yield, effective yield and tax-equivalent yield provided by the
Trust are carried to at least the nearest hundredth of one percent. Any fees
imposed by Northern, its affiliates or correspondent banks on their customers in
connection with investments in Shares of the Portfolios are not reflected in the
calculation of yields for the Portfolios.

The annualized yield of each Portfolio with respect to Shares for the seven-day
period ended November 30, 1997 was as follows:

</TABLE>
Each Portfolio's yields fluctuate, unlike bank deposits or other investments
which pay a fixed yield for a stated period of time. The annualization of one
week's income is not necessarily indicative of future actual yields.  Actual
yields will depend on such variables as portfolio quality, average portfolio
maturity, the type of portfolio instruments acquired, changes in money market
interest rates, portfolio expenses and other factors.  Yields are one basis
investors may use to analyze a Portfolio as compared to other money market funds
and other investment vehicles.  However, yields of other money market funds and
other investment vehicles may not be comparable because of the foregoing
variables, and differences in the methods used in valuing their portfolio
instruments, computing net asset value and determining yield.

Each Portfolio may also quote from time to time its total return in accordance
with SEC regulations.

The yields and total return returns of the Portfolios Service Shares and Premier
Shares are calculated separately from the calculations of the yield and total
return of the Shares described in this Additional Statement.     

                           AMORTIZED COST VALUATION

As stated in the Prospectus, each Portfolio seeks to maintain a net asset value
of $1.00 per share and, in this connection, values its instruments on the basis
of amortized cost pursuant to Rule 2a-7 under the 1940 Act. This method values a
security at its cost on the date of purchase and thereafter assumes a constant
amortization to maturity of any discount or premium, regardless of the impact of
fluctuating interest rates on the market value of the instrument. While this
method provides certainty in valuation, it may result in periods during which

                                     B-31
<PAGE>
 
    
value, as determined by amortized cost, is higher or lower than the price a
Portfolio would receive if the Portfolio sold the instrument. During such
periods the yield to investors in the Portfolio may differ somewhat from that
obtained in a similar entity which uses available indications as to market value
to value its portfolio instruments. For example, if the use of amortized cost
resulted in a lower (higher) aggregate Portfolio value on a particular day, a
prospective investor in the Portfolio would be able to obtain a somewhat higher
(lower) yield and ownership interest than would result from investment in such
similar entity and existing investors would receive less (more) investment
income and ownership interest. However, the Trust expects that the procedures
and limitations referred to in the following paragraphs of this section will
tend to minimize the differences referred to above.

Under Rule 2a-7, the Trust's Board of Trustees, in supervising the Trust's
operations and delegating special responsibilities involving portfolio
management to Northern, has established procedures that are intended, taking
into account current market conditions and the Portfolios' investment
objectives, to stabilize the net asset value of each Portfolio, as computed for
the purposes of purchases and redemptions, at $1.00 per share. The Trustees'
procedures include periodic monitoring of the difference (the "Market Value
Difference") between the amortized cost value per share and the net asset value
per share based upon available indications of market value. Available
indications of market value used by the Trust consist of actual market
quotations or appropriate substitutes which reflect current market conditions
and include (a) quotations or estimates of market value for individual portfolio
instruments and/or (b) values for individual portfolio instruments derived from
market quotations relating to varying maturities of a class of money market
instruments. In the event the Market Value Difference of a given Portfolio
exceeds certain limits or Northern believes that the Market Value Difference may
result in material dilution or other unfair results to investors or existing
shareholders, the Trust will take action in accordance with the 1940 Act and the
Trustees will take such steps as they consider appropriate (e.g., selling
portfolio instruments to shorten average portfolio maturity or to realize
capital gains or losses, reducing or suspending shareholder income accruals,
redeeming shares in kind, or utilizing a net asset value per share based upon
available indications of market value which under such circumstances would vary
from $1.00) to eliminate or reduce to the extent reasonably practicable any
material dilution or other unfair results to investors or existing shareholders
which might arise from Market Value Differences. In particular, if losses were
sustained by a Portfolio, the number of outstanding shares might be reduced in
order to maintain a net asset value per share of $1.00. Such reduction would be
effected by having each shareholder proportionately contribute to the
Portfolio's capital the necessary shares to restore such net asset value per
share. Each     

                                     B-32
<PAGE>

     
shareholder will be deemed to have agreed to such contribution in these
circumstances by investing in the Portfolio.

Rule 2a-7 requires that each Portfolio limit its investments to instruments
which Northern determines (pursuant to guidelines established by the Board of
Trustees) to present minimal credit risks and which are "Eligible Securities" as
defined by the SEC and described in the Prospectus. The Rule also requires that
each Portfolio maintain a dollar-weighted average portfolio maturity (not more
than 90 days) appropriate to its policy of maintaining a stable net asset value
per share and precludes the purchase of any instrument deemed under the Rule to
have a remaining maturity of more than 13 months. Should the disposition of a
portfolio security result in a dollar-weighted average portfolio maturity of
more than 90 days, the Rule requires a Portfolio to invest its available cash in
such a manner as to reduce such maturity to the prescribed limit as soon as
reason ably practicable.

                             DESCRIPTION OF SHARES

The Trust Agreement permits the Trust's Board of Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of one or more
separate series representing interests in different investment portfolios. The
Trustees may hereafter create series in addition to the Trust's existing
eighteen series which represent interests in the eighteen respective portfolios.
The Trust Agreement also permits the Board of Trustees to classify or reclassify
any unissued shares into additional series or subseries within a series.
Pursuant to such authority, the Trustees have authorized the issuance of an
unlimited number of shares of beneficial interest in three separate classes of
shares in each of the Portfolios: Shares, Service Shares and Premier Shares.
This Additional Statement ((and the ----- Paragraphs) relate only to the class
of shares of the four Portfolios discussed herein. For information on the other
share classes in the Portfolios and on the Trust's other investment portfolios
call Goldman Sachs at the toll-free number on page 1. Under the terms of the
Trust Agreement, each share of each Portfolio is without par value, represents
an equal proportionate interest in the particular Portfolio with each other
share of its class in the same Portfolio and is entitled to such dividends and
distributions out of the income belonging to the Portfolio as are declared by
the Trustees. Upon any liquidation of a Portfolio, shareholders of each class of
a Portfolio are entitled to share pro rata in the net assets belonging to that
class available for distribution. Shares do not have any preemptive or
conversion rights. The right of redemption is described under "Investing-
Redemption of Shares" in the Prospectus and under "Amortized Cost Valuation" in
this Additional Statement. In addition, pursuant to the terms of the 1940 Act,
the right of a shareholder to redeem shares and the date of payment by a
Portfolio may be suspended for more than     

                                     B-33
<PAGE>

     
seven days (a) for any period during which the New York Stock Exchange is
closed, other than the customary weekends or holidays, or trading in the markets
the Portfolio normally utilizes is closed or is restricted as determined by the
SEC, (b) during any emergency, as determined by the SEC, as a result of which it
is not reasonably practicable for the Portfolio to dispose of instruments owned
by it or fairly to determine the value of its net assets, or (c) for such other
period as the SEC may by order permit for the protection of the shareholders of
the Portfolio. The Trust may also suspend or postpone the recordation of the
transfer of its shares upon the occurrence of any of the foregoing conditions.
In addition, shares of each Portfolio are redeemable at the unilateral option of
the Trust if the Trustees determine in their sole discretion that failure to so
redeem may have material adverse consequences to the shareholders of the
Portfolio. Shares when issued as described in the Prospectus are validly issued,
fully paid and nonassessable, except as stated below.

The proceeds received by each Portfolio for each 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 and constitute the underlying assets of that Portfolio. The underlying assets
of each Portfolio will be segregated on the books of account, and will be
charged with the liabilities in respect to that Portfolio and with a share of
the general liabilities of the Trust. Expenses with respect to the Portfolios
are normally allocated in proportion to the net asset value of the respective
Portfolios except where allocations of direct expenses can otherwise be fairly
made.

Rule 18f-2 under the 1940 Act provides that any matter required to be submitted
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
Portfolio affected by the matter. A Portfolio is affected by a matter unless it
is clear that the interests of each Portfolio in the matter are substantially
identical or that the matter does not affect any interest of the Portfolio.
Under the Rule, the approval of an investment advisory agreement or any change
in a fundamental investment policy would be effectively acted upon with respect
to a Portfolio only if approved by a majority of the outstanding shares of such
Portfolio. However, the Rule also provides that the ratification of the
appointment of independent accountants, the approval of principal underwriting
contracts and the election of Trustees are exempt from the separate voting
requirements stated above. In addition, shareholders of each of the classes in a
particular investment portfolio have equal voting rights except that only shares
of a particular class of an investment portfolio will be entitled to vote on
matters submitted to a vote of shareholders (if any) relating to     

                                      B-34
<PAGE>
 
shareholder servicing expenses and transfer agency fees that are payable by that
class.
    
     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 entitled, as determined by the Trustees
without the vote or consent of shareholders, either to one vote for each share
to one vote for each dollar of net asset value represented by such Shares on all
matters presented to Shareholders, including the election of Trustees (this
method of voting being referred to as "dollar-based voting"). However, to the
extent required by the 1940 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 meeting. The Shareholders
of the Trust will have voting rights only with respect to the limited number of
matters specified in the Trust Agent and such other matters as the Trustees may
determine or may be required by law.     
    
     The Trust authorizes the Trustees, without approval (except as stated in
the next paragraph), 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 the Trust, or
any series thereof. In addition, the Trustees, without shareholder approval, may
adopt a "master-feeder" structure by investing substantially all of the assets
of a series of the Trust in the securities of another open-end investment
company or pooled portfolio.    
    
     The Trust Agent also authorizes the Trustees, in connection with the
merger, consolidation, termination or other reorganization of the Trust or any
series or class, to classify the Shareholders of any class into one or more
separate groups and to provide for the different treatment of Shares held by the
different groups, provided that such merger, consolidation, termination or other
reorganization is approved by a majority of the outstanding voting securities
(as defined in the 1940 Act) of each group of Shareholders that are so
classified.    

    The Trust Agent permits the Trustees to amend the Trust Agent 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 voting provisions of the Trust Agent; or (iv) that the Trustees
determine to submit to Shareholders.    


                                      B-35
<PAGE>

     
     The Trust Agent 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 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.    

Under the Delaware Business Trust Act (the "Delaware Act"), shareholders are not
personally liable for obligations of the Trust. The Delaware Act entitles a
shareholder of the Trust to the same limitation of liability as is available to
shareholders of private for-profit corporations. However, no similar statutory
or other authority limiting business trust shareholder liability exists in many
other states. As a result, to the extent that the Trust or a shareholder is
subject to the jurisdiction of courts in such other states, those courts may not
apply Delaware law and may subject the shareholders to liability. To offset this
risk, the Trust Agreement (i) contains an express disclaimer of shareholder
liability for acts or obligations of the Trust and requires that notice of such
disclaimer be given in each agreement, obligation and instrument entered into or
executed by the Trust or its Trustees and (ii) provides for indemnification out
of the property of the applicable series of the Trust of any shareholder held
personally liable for the obligations of the Trust 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. Thus, the risk of a shareholder incurring financial
loss beyond his or her investment because of shareholder liability is limited to
circumstances in which all of the following factors are present: (1) a court
refuses to apply Delaware law; (2) the liability arises under tort law or, if
not, no contractual limitation of liability is in effect; and (3) the applicable
series of the Trust is unable to meet its obligations.

    
The Trust Agreement provides that the Trustees will not be liable to any person
other than the Trust or a shareholder and that a Trustee will not be liable for
any act as a Trustee. However, nothing in the Trust Agreement protects a Trustee
against any liability to which he or she would otherwise be subject by reason of
willful misfeasance, bad faith, gross negligence or     

                                      B-36
<PAGE>

     
reckless disregard of the duties involved in the conduct of such person's
office.

The Trust Agreement provides that each shareholder, by virtue of becoming such,
will be held to have expressly assented and agreed to the terms of the Trust
Agreement and to have become a party thereto.

In addition to the requirements of Delaware law, the Trust Agent provides that a
Shareholder of the Trust may bring a derivative action on behalf of the Trust
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 Trust, or 10% of the outstanding Shares 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 Shareholder request and to investigate the basis
of such claim. The Trust Agent also provides that no person, other than the
Trustees, who is not a Shareholder of a particular series or class shall be
entitled to bring any derivative action, suit or other proceeding on behalf of
or with respect to such series or class. The Trustees will be entitled to retain
counsel or other advisers in considering the merits of the request any may
require an undertaking by the Shareholders making such request to reimburse the
Trust for the expense of any such advisers to reimburse the Trust for the
expense of any such advisers in the event that the Trustees determine not to
bring such action.

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 Trust Instrument with
respect to such 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 Dalaware Trust. 

Shares are held of record by Northern for the benefit of its customers and the
customers of its affiliates and correspondent banks who have invested in the
Portfolios. As of March 11, 1998, the trustees and officers of the Trust as a
group owned less than 1% of the outstanding shares of beneficial interest of
each Portfolio. Northern has advised the Trust that the following persons (whose
mailing address is: c/o The Northern Trust Company, 50 South LaSalle, Chicago,
IL 60675) beneficially owned five percent or more of the outstanding shares of
the Portfolios as of March 11, 1998:

ADDITIONAL INFORMATION CONCERNING TAXES

General

Each Portfolio is treated as a separate corporate entity under the Internal
Revenue Code of 1986, as amended (the "Code"), and intends to qualify as a
regulated investment company. By following this policy, each Portfolio expects
to eliminate or reduce to a nominal amount the Federal income taxes to which it
may be subject. If for any taxable year a Portfolio does not qualify for the
special Federal tax treatment afforded regulated investment companies, all of
the Portfolio's taxable income would be subject to tax at regular corporate
rates without any deduction for distributions to shareholders. In such event,
the Portfolio's distributions (including amounts derived from interest on
Municipal Instruments in the case of the Tax-Exempt Portfolio) would be taxable
as ordinary income for Federal income tax purposes to the Portfolio's
shareholders, to the extent of its current and accumulated earnings and profits,
and would be eligible for the dividends received deduction in the case of
corporate shareholders.

In order to qualify as a regulated investment company for a taxable year under
the Code, each Portfolio must comply with certain requirements. First, each
Portfolio must distribute to its shareholders an amount equal to at least the
sum of 90% of its investment company taxable income and 90% of its net tax-
exempt interest income (if any) (the "Distribution Requirement"). At least 90%
of the gross income of each Portfolio must be derived from dividends, interest,
payments with respect to securities loans, gains from the sale or other
disposition of stock, securities or foreign currencies, and other income
(including, but not limited to, gains from options, futures or forward
contracts) derived with respect to the Portfolio's business of investing in such
stock, securities or currencies (the "Income Requirement"). Finally, at the
close of each quarter of its taxable year, at least 50% of the value of each
Portfolio's assets must consist of cash and cash items, U.S. Government
securities, securities of other regulated investment companies, and securities
of other issuers (as to which the Portfolio has not invested more than 5% of the
value of its total assets in securities of such issuer and as to which the
Portfolio      

                                     B-38

<PAGE>
    
does not hold more than 10% of the outstanding voting securities of such issuer)
and no more than 25% of the value of each Portfolio's total assets may be
invested in the securities of any one issuer (other than U.S. Government
securities and securities of other regulated investment companies), or in two or
more issuers which such Portfolio controls and which are engaged in the same or
similar trades or businesses.

Each Portfolio will designate any distribution of the excess of net long-term
capital gain over net short-term capital loss as a capital gain dividend in a
written notice mailed to shareholders within 60 days after the close of the
Portfolio's taxable year.

Ordinary income of individuals (including short-term capital gains) is taxable
at a maximum marginal rate of 39.6%, but because of limitations on itemized
deductions otherwise allowable and the phase-out of personal exemptions, the
maximum effective marginal rate of tax for some taxpayers may be higher. Under
the Taxpayer Relief Act of 1997, for capital gains on securities recognized
after July 28, 1997, the maximum tax rate for individuals is 20% if the property
was held more than 18 months; for property held for more than 12 months, but not
longer than 18 months, the maximum tax rate on capital gains continues to be
28%. For corporations, long-term capital gains and ordinary income are both
taxable at a maximum marginal rate of 35%.

A 4% nondeductible excise tax is imposed on regulated investment companies that
fail to currently distribute specified percentages of their ordinary taxable
income and capital gain net income (excess of capital gains over capital
losses). Each Portfolio intends to make sufficient distributions or deemed
distributions of its ordinary taxable income and any capital gain net income
prior to the end of each calendar year to avoid liability for this excise tax.

The Trust will be required in certain cases to withhold and remit to the U.S.
Treasury 31% of taxable dividends and gross sale proceeds paid to any
shareholder (i) who has provided either an incorrect tax identification number
or no number at all, (ii) who is subject to backup withholding by the Internal
Revenue Service for failure to report the receipt of taxable interest or
dividend income properly, or (iii) who has failed to certify to the Trust, when
required to do so, that he or she is not subject to backup withholding or that
he or she is an "exempt recipient."

Special Tax Considerations Pertaining to the Tax-Exempt Portfolio

As described above and in the Prospectus, the Tax-Exempt Portfolio is designed
to provide investors with current tax-exempt interest income. The Portfolio is
not intended to constitute a balanced investment program and is not designed for
investors seeking capital appreciation or maximum tax-exempt income    

                                     B-39

<PAGE>
    
irrespective of fluctuations in principal. Shares of the Portfolio 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, would not gain any additional benefit from the Portfolio's
dividends being tax-exempt. In addition, the Portfolio may not be an appropriate
investment for persons or entities that 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
which regularly uses a part of such facilities in its 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, or which occupies more than 5% of the usable area of such
facilities or for which such facilities or a part thereof were specifically
constructed, reconstructed or acquired. "Related persons" include certain
related natural persons, affiliated corporations, partnerships and its partners
and an S corporation and its shareholders.

In order for the Tax-Exempt Portfolio to pay Federal exempt-interest dividends
with respect to any taxable year, at the close of each taxable quarter at least
50% of the aggregate value of the Portfolio must consist of tax-exempt
obligations. An exempt-interest dividend is any dividend or part thereof (other
than a capital gain dividend) paid by the Portfolio and designated as an exempt-
interest dividend in a written notice mailed to shareholders not later than 60
days after the close of the Portfolio's taxable year. However, the aggregate
amount of dividends so designated by the Portfolio cannot exceed the excess of
the amount of interest exempt from tax under Section 103 of the Code received by
the Portfolio during the taxable year over any amounts disallowed as deductions
under Sections 265 and 171(a)(2) of the Code. The percentage of total dividends
paid by the Portfolio with respect to any taxable year which qualifies as
Federal exempt-interest dividends will be the same for all shareholders
receiving dividends from the Portfolio with respect to such year.

Interest on indebtedness incurred by a shareholder to purchase or carry
Portfolio shares generally is not deductible for Federal income tax purposes if
the Portfolio's distributions are not subject to Federal income tax.

Foreign Investors

Foreign shareholders generally will be subject to U.S. withholding tax at a rate
of 30% (or a lower treaty rate, if applicable) on distributions by a Portfolio
of net interest income, other ordinary income, and the excess, if any, of net
    

                                     B-40

<PAGE>
 
short-term capital gain over net long-term capital loss for the year. For this
purpose, foreign shareholders include individuals other than U.S. citizens,
residents and certain nonresident aliens, and foreign corporations,
partnerships, trusts and estates. A foreign shareholder generally will not be
subject to U.S. income or withholding tax in respect of proceeds from or gain on
the redemption of shares or in respect of capital gain dividends, provided such
shareholder submits a statement, signed under penalties of perjury, attesting to
such shareholder's exempt status. Different tax consequences apply to a foreign
shareholder engaged in a U.S. trade or business. Foreign shareholders should
consult their tax advisers regarding the U.S. and foreign tax consequences of
investing in the Trust.


Conclusion

The foregoing discussion is based on tax laws and regulations which are in

shareholders, and the discussion here and in the Prospectus is not intended as a
substitute for careful tax planning.  Shareholders are advised to consult their
tax advisers with specific reference to their own tax situation, including the

                       DESCRIPTION OF SECURITIES RATINGS

The following is a description of the securities ratings of Moody's Investors
Service, Inc. ("Moody's"), Standard & Poor's Ratings Group, Inc., a division of
McGraw Hill ("S&P"), Duff & Phelps Credit Rating Co. ("D&P"), Fitch IBCA, Inc.
("Fitch") and Thomson BankWatch, Inc. ("TBW").

Long-Term Corporate and Tax-Exempt Debt Ratings

The two highest ratings of Moody's for tax-exempt and corporate bonds are Aaa
and Aa. Tax-exempt and corporate bonds rated Aaa are judged to be of the "best
quality." The rating of Aa is assigned to bonds which are of "high quality by
all standards." Aa bonds are rated lower than Aaa bonds because margins of
protection may not be as large or fluctuations of protective elements may be of
greater amplitude or there may be other elements which make the long-term risks
appear somewhat larger. Moody's may modify a rating of Aa by adding numerical
modifiers of 1, 2 or 3 to show relative standing within the Aa category. The
foregoing ratings for tax-exempt bonds are sometimes presented in parentheses
preceded with a "con" indicating the bonds are rated conditionally. Such
parenthetical rating denotes the probable credit stature upon completion of
construction or elimination of the basis of the condition. The notation (P) when
applied to forward delivery bonds indicates that the rating is provisional
pending delivery of the bonds. The rating may be revised prior to delivery if
changes occur in the legal documents or the underlying credit quality of the
bonds. In addition, Moody's has advised that the short-term credit risk of a
long-term instrument sometimes carries a MIG rating or one of the commercial
paper ratings described below.
    
The two highest ratings of S&P for tax-exempt and corporate bonds are AAA and
AA. Bonds rated AAA bear the highest rating assigned by S&P to a debt obligation
and the AAA rating indicates that the obligor's capacity to meet its financial
commitment or the obligation is an extremely strong capacity to pay interest and
repay principal. Bonds rated AA by S&P demonstrate that the obligor's capacity
to meet its financial commitment or the obligation is strong, and differ from
AAA issues only in small degree. The AA rating may be modified by an addition of
a plus (+) or minus (-) sign to show relative standing within the major rating
category. S&P may attach the rating "r" to highlight derivative, hybrid and
certain other obligations that S&P believes may experience high volatility or
high variability in expected returns due to non-credit risks.    

The two highest ratings of D&P for tax-exempt and corporate fixed-income
securities are AAA and AA. Securities rated AAA are of the highest credit
quality. The risk factors are considered

                                      1-A
<PAGE>
    
to be negligible, being only slightly more than for risk-free U.S. Treasury
debt. Securities rated AA are of high credit quality. Protection factors are
strong. Risk is modest but may vary slightly from time to time because of
economic conditions. The AA rating may be modified by an addition of a plus (+)
or minus (-) sign to show relative standing within the major rating category.

The two highest ratings of Fitch for tax-exempt and corporate bonds are AAA and
AA. AAA bonds are considered to be investment grade and of the highest credit
quality. The obligor is judged to have an exceptionally strong capacity for
timely payment of financial commitments, which is unlikely to be affected by
reasonably foreseeable events. AA bonds are considered to be investment grade
and of very high credit quality. These ratings denote a very low expectation of
investment risk and indicate very strong capacity for timely payment of
financial commitments. Because bonds rated in the AAA and AA categories are not
significantly vulnerable to foreseeable future developments, short-term debt of
these issuers is generally rated F-1+. Plus (+) and minus (-) signs are used
with the AA rating symbol to indicate relative standing within the rating
category.

The two highest ratings of TBW for corporate bonds are AAA and AA. Bonds rated
AAA are of the highest credit quality. The ability of the obligor to repay
principal and interest on a timely basis is considered to be extremely high.
Bonds rated AA indicate a very strong ability on the part of the obligor to
repay principal and interest on a timely basis with limited incremental risk
versus issues rated in the highest category. These ratings may be modified by
the addition of a plus (+) or minus (-) sign to show relative standing within
the rating categories. TBW does not rate tax-exempt bonds.

Tax-Exempt Note Ratings

Moody's ratings for state and municipal notes and other short-term obligations
are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade. MIG-1/VMIG-1
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 denotes high quality. Margins of protection
are ample although not so large as in the preceding group.

S&P describes its SP-1 rating of municipal notes as follows: Strong capacity to
pay principal and interest. Those issues determined to possess very strong
characteristics will be given a plus (+) designation." Municipal notes rated 
SP-2 are deemed to have satisfactory capacity to pay principal and interest.
     

                                      2-A
<PAGE>
    
D&P uses the fixed-income ratings described above under "Corporate and Tax-
Exempt Bond Ratings" for tax-exempt notes and other short-term obligations.

Fitch's short-term ratings apply to tax-exempt and corporate debt obligations
that are payable on demand or have original maturities of up to three years,
including commercial paper and municipal and investment notes. The highest
ratings of Fitch for short-term securities are F1+, F1 and F2. F1+ securities
possess exceptionally strong credit quality. Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment. F1
securities possess very strong credit quality. Issues assigned this rating
reflect an assurance of timely payment only slightly less in degree than issues
rated F1+. F2 securities possess good credit quality. Issues carrying this
rating have a satisfactory degree of assurance for timely payment, but the
margin of safety is not as great as the F1+ and F1 ratings.

TBW does not rate tax-exempt notes.

Short-Term Corporate and Tax-Exempt Debt Ratings

Short-term ratings, set forth below (except TBW's), are applied to tax-exempt as
well as taxable debt.

Moody's short-term debt ratings are opinions of the ability of issuers to repay
punctually senior debt obligations not having an original maturity in excess of
one year. Issuers rated Prime-1 (or related supporting institutions) in the
opinion of Moody's have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 (or related supporting
institutions) are considered to have a strong capacity for repayment of short-
term promissory obligations.

S&P's commercial paper ratings are current assessments of the likelihood of
timely payment of debt considered short-term in the relevant market. The A-1
designation indicates that the obligor's capacity to meet its financial
commitment is strong. Those issues for which the obligor's capacity to meet its
financial commitment is extremely strong will be denoted with a plus (+) sign
designation. The A-2 designation indicates that the obligor's capacity to meet
its financial commitment is satisfactory. However, the relative degree of safety
is not as high as for issues designated A-1.

The two highest ratings of D&P for commercial paper are D-1 and D-2. D&P employs
three designations, D-1 plus, D-1 and D-1 minus, within the highest rating
category. D-1 plus indicates highest certainty of timely payment. Short-term
liquidity including internal operating factors, and/or ready access to
alternative sources of funds, is judged to be outstanding, and safety is just
below risk-free U.S. Treasury short-term      

                                      3-A
<PAGE>
     
obligations. D-1 indicates very high certainty of timely payment. Liquidity
factors are excellent and supported by strong fundamental protection factors.
Risk factors are considered to be minor. D-1 minus indicates high certainty of
timely payment. Liquidity factors are strong and supported by good fundamental
protection factors. Risk factors are very small. D2 indicates good certainty of
timely payment. Liquidity factors and company fundamentals are sound. Although
ongoing funding needs may enlarge total financing requirements, access to
capital markets is good. Risk factors are small. 

Fitch uses the short-term ratings described above under "Tax-Exempt Note
Ratings" for commercial paper.

TBW's short-term ratings assess the likelihood of an untimely or incomplete
payment of principal or interest of unsubordinated debt instruments having a
maturity of one year or less which are issued by United States commercial banks,
thrifts and non-bank banks; non-United States banks; and broker-dealers and
other financial institutions. The two highest short-term ratings of TBW are TBW-
1 and TBW-2. Debt rated TBW-1 indicates a very high degree of likelihood that
principal and interest will be paid on a timely basis. The TBW-2 designation
indicates that while the degree of safety regarding timely payment of principal
and interest is strong, the relative degree of safety is not as high as for
issues rated TBW-1.

MANAGEMENT'S DISCUSSION OF PORTFOLIO PERFORMANCE


BENCHMARK DIVERSIFIED ASSETS PORTFOLIO
BENCHMARK GOVERNMENT PORTFOLIO
BENCHMARK GOVERNMENT SELECT PORTFOLIO
 
With respect to interest rate changes, the Federal Reserve was fairly quiet
during the fiscal year. The only change came on March 25, 1997, when the Fed
implemented a quarter-point interest rate increase. What had a greater impact
on interest rates was the Asian market crisis, which resulted in economic
instability and the devaluation of currencies throughout the region.
Consequently, there was a flight to quality in the U.S. market, where interest
rates fell consistently and dramatically despite a robust economy. Yield
curves flattened, and in some sectors they inverted.
  During the first half of the fiscal year, the government portfolios
maintained average maturities that were short of their peer groups. We shifted
our strategy in the second half, as we extended the portfolios' average
maturities relative to their peer groups. We also implemented a barbell
strategy during the year, whereby shorter-term securities were purchased for
liquidity and longer-term securities were added for their yield advantages.
This strategy also provided a hedge against deflation. We will continue with
this strategy as long as the Federal Reserve maintains a tightening bias.
  We did not make many changes in the investment composition of the
Diversified Assets Portfolio during the fiscal year. The heaviest
concentration of securities continues to be in tier one commercial paper,
where there is the greatest yield advantage. At the end of the fiscal year,
the Portfolio's average maturity was 45 days, which remains consistent with
other money market funds with the same investment structure. Providing
liquidity, maintaining a high credit quality and offering an attractive yield
remain the primary goals for the Portfolio.

BENCHMARK TAX-EXEMPT MONEY MARKET PORTFOLIO
 
The Portfolio continued to benefit from a barbell maturity strategy during
fiscal 1997. Due to our belief that the Federal Reserve would hold interest
rates relatively stable during 1997, we "barbelled" the Portfolio with very
short-term and one-year securities. This enabled us to extend the Portfolio's
average maturity longer than that of its peer group and still keep it
responsive to any change in short-term interest rates. The yield curve in the
short-term tax-exempt market was flat, especially inside of six months. As a
result, the one-year paper added increased yield to the Portfolio.
  The short-term, tax-exempt market is a technically driven, cyclical market.
There are certain times of the year (such as tax time, calendar year-end, and
the end of June and the first part of July) when our market has wide swings in
both assets and yields. We have to anticipate these cycles and be able to
manage the volatile swings in assets and yields.
  We have shortened the Portfolio's average maturity to a level that is about
equal to that of the Portfolio's peer group. We did this because we believe
that recent economic data point to an increased likelihood of the Federal
Reserve raising interest rates in early 1998. Our current maturity structure
should allow the Portfolio to better respond to any increase in interest
rates.

The Benchmark Funds
Money Market Portfolios
- -------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
November 30, 1997

1. ORGANIZATION
The Benchmark Funds (the "Trust") is a Massachusetts business trust registered
under the Investment Company Act of 1940 (as amended) as an open-end
management investment company. The Trust includes seventeen portfolios, each
with its own investment objective. The Northern Trust Company ("Northern")
acts as the Trust's investment adviser, transfer agent, and custodian.
Goldman, Sachs & Co. ("Goldman Sachs") acts as the Trust's administrator and
distributor. Presented herein are the financial statements of the money market
portfolios.
 The Trust includes four diversified money market portfolios: Diversified
Assets Portfolio, Government Portfolio, Government Select Portfolio and Tax-
Exempt Portfolio (the "Portfolios").
 
2. SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of significant accounting policies consistently
followed by the Portfolios in the preparation of their financial statements.
These policies are in conformity with generally accepted accounting principles
("GAAP"). The presentation of financial statements in conformity with GAAP
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
(a) Investment Valuation
Investments are valued at amortized cost, which approximates market value.
Under the amortized cost method, 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) Repurchase Agreements
During the term of a repurchase agreement, the market value of the underlying
collateral, including accrued interest, is required to exceed the market value
of the repurchase agreement. The underlying collateral for all repurchase
agreements is held in a customer-only account of Northern, as custodian for
the Trust, at the Federal Reserve Bank of Chicago.
 Each Portfolio may enter into joint repurchase agreements with non-affiliated
counterparties through a master repurchase agreement with Northern. Northern
administers and manages these repurchase agreements in accordance with and as
part of its duties under its investment advisory agreements with the
Portfolios and does not collect any additional fees from the Portfolios. The
Diversified Assets and Government Portfolios had entered into such joint
repurchase agreements as of November 30, 1997, as reflected in the
accompanying Statements of Investments.
 
(c) Interest Income
Interest income is recorded on the accrual basis and includes amortization of
discounts and premiums.
 
(d) 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 of its taxable income and tax-exempt income to its
unitholders. Therefore, no provision is made for federal taxes.
 At November 30, 1997, there were capital loss carryforwards for U.S. federal
tax purposes of approximately $1,367,000 and $93,000 for the Diversified
Assets and Government Portfolios, respectively. These amounts are available to
be carried forward to offset future capital gains to the extent permitted by
applicable laws or regulations. These capital loss carryforwards expire in
2002.
 
(e) Expenses
Expenses arising in connection with a specific Portfolio are allocated to that
Portfolio.
 Expenses incurred which do not specifically relate to an individual Portfolio
are allocated among the Portfolios based on each Portfolio's relative average
net assets for the year.
 
(f) Distributions
Each Portfolio's net investment income is declared daily as a dividend to
unitholders of record as of 3:00 p.m., Chicago time. Net realized short-term
capital gains, if any in excess of net capital loss carryforwards, are
declared and distributed at least annually.
 Distributions of net investment income with respect to a calendar month
(including with respect to units redeemed at any time during the month) are
made as soon as practicable following the end of the month. Distributions are
made by each Portfolio to Northern in cash or automatically reinvested in
additional units of the Portfolio.

NOTES TO FINANCIAL STATEMENTS
November 30, 1997

Northern has undertaken to credit or arrange for the crediting of such
distributions to each unitholder's account with Northern, its affiliates or
its correspondents.
 
3. ADVISORY, TRANSFER AGENCY, CUSTODIAN AND OTHER AGREEMENTS
As compensation for the services rendered as investment adviser, including the
assumption by Northern of the expenses related thereto, Northern is entitled
to a fee, computed daily and payable monthly, at an annual rate of .25% of
each Portfolio's average daily net assets.
 Until further notice, Northern has voluntarily agreed to waive .15% of its
advisory fee for the Government Select Portfolio, reducing such fee to .10%
per annum. The effect of this waiver by Northern for the year ended November
30, 1997 was to reduce advisory fees as shown on the accompanying Statements
of Operations.
 As compensation for the services rendered as custodian and transfer agent,
including the assumption by Northern of the expenses related thereto, Northern
receives compensation based on a pre-determined schedule of charges approved
by the Board.
 
4. ADMINISTRATION AND DISTRIBUTION AGREEMENTS
The Trust has an administration agreement (as amended May 1, 1997) with
Goldman Sachs whereby each Portfolio pays the Administrator a fee, computed
daily and payable monthly, at an annual rate of .10% of each Portfolio's daily
net assets.
 In addition, if in any fiscal year the sum of a Portfolio's expenses,
including the administration fee, but excluding the investment advisory fee
and transfer agency fee payable to Northern pursuant to its agreements with
the Trust, servicing fees, and extraordinary expenses (such as taxes, interest
and indemnification expenses), exceeds on an annualized basis .10% of a
Portfolio's average net assets, Goldman Sachs will reimburse each Portfolio
for the amount of the excess pursuant to the terms of the administration
agreement.
 Prior to May 1, 1997 each Portfolio paid the Administrator a fee, computed
daily and payable monthly, based on the average net assets of each Portfolio
at the rates set forth below:
 
<TABLE>
<CAPTION>
Average net assets                Rate
- ---------------------------------------
<S>                               <C>
For the first $100,000,000        .250%
For the next $200,000,000         .150
For the next $450,000,000         .075
For net assets over $750,000,000  .050
- ---------------------------------------
</TABLE>
 
 Prior to May 1, 1997, Goldman Sachs voluntarily agreed to waive a portion of
its administrative fees should overall administration fees earned during the
preceding year exceed certain specified levels. No waiver was required under
this agreement during the year ended November 30, 1997. Furthermore, Goldman
Sachs voluntarily agreed to reimburse each Portfolio for certain expenses in
the event that such expenses, as defined, exceed on an annualized basis .10%
of its average daily net assets.
 Expenses reimbursed during the year ended November 30, 1997 are shown on the
accompanying Statements of Operations.
 Goldman Sachs receives no compensation under the distribution agreement.
 
5. BANK LOANS
The Trust maintains a $5,000,000 revolving bank credit line and a $15,000,000
conditional revolving credit line for liquidity and other purposes. Borrowings
under this arrangement bear interest at 1% above the Fed Funds rate and are
secured by pledged securities equal to or exceeding 120% of the outstanding
balance.
 There were no borrowings under this agreement during the year ended November
30, 1997.

REPORT OF INDEPENDENT AUDITORS
 
To the Unitholders and Trustees of
The Benchmark Funds
Money Market Portfolios
 
We have audited the accompanying statements of assets and liabilities,
including the statements of investments, of the Diversified Assets,
Government, Government Select and Tax-Exempt Portfolios, comprising the Money
Market Portfolios of The Benchmark Funds, as of November 30, 1997, and the
related statements of operations for the year then ended and changes in net
assets for each of the two years in the period then ended and financial
highlights for the periods indicated therein. These financial statements and
financial highlights are the responsibility of the Portfolios' management. Our
responsibility is to express an opinion on these financial statements and
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
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. Our procedures included verification of the
investments owned at November 30, 1997 by physical examination of the
securities held by the custodian and by correspondence with central
depositories 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 the
Diversified Assets, Government, Government Select and Tax-Exempt Portfolios,
comprising the Money Market Portfolios of The Benchmark Funds, at November 30,
1997, the results of their operations for the year then ended and the changes
in their net assets for each of the two years in the period then ended and
financial highlights for the periods indicated therein, in conformity with
generally accepted accounting principles.

                              THE BENCHMARK FUNDS
    (Advised by The Northern Trust Company and Northern Trust Quantitative
                                Advisors, Inc.)
 
This Prospectus describes six fixed income, one balanced, one global asset and
six equity portfolios (the "Portfolios") offered by The Benchmark Funds (the
"Trust") to institutional investors.
 
 The U.S. GOVERNMENT SECURITIES PORTFOLIO seeks to maximize total return with
 reasonable risk by investing in a broad range of U.S. Government securities
 and maintaining a dollar-weighted average maturity of between 1 and 5 years.
 The SHORT-INTERMEDIATE BOND PORTFOLIO seeks to maximize total return
 consistent with reasonable risk by investing in a broad range of bonds and
 other fixed income securities and maintaining a dollar-weighted average
 maturity of between 2 and 5 years.
 The U.S. TREASURY INDEX PORTFOLIO seeks to provide investment results
 approximating the performance of the Lehman Brothers Treasury Bond Index (the
 "Lehman Index") by investing primarily in securities represented in the
 Lehman Index.
 The BOND PORTFOLIO seeks to maximize total return consistent with reasonable
 risk by investing in a broad range of bonds and other fixed income securities
 and maintaining a dollar-weighted average maturity of between 5 and 15 years.
 The INTERMEDIATE BOND PORTFOLIO seeks to maximize total return consistent
 with reasonable risk by investing in a broad range of bonds and other fixed
 income securities and maintaining a dollar-weighted average maturity of
 between 3 and 10 years.
 The INTERNATIONAL BOND PORTFOLIO seeks to maximize total return consistent
 with reasonable risk by investing primarily in a broad range of bonds and
 other fixed income securities of foreign issuers while maintaining a dollar-
 weighted average maturity of between 3 and 11 years.
 The BALANCED PORTFOLIO seeks to provide long-term capital appreciation and
 current income by investing in stocks, bonds and cash equivalents.
    
 The GLOBAL ASSET PORTFOLIO seeks to provide long-term capital appreciation
 and current income by allocating its assets for investment among four market
 segments: domestic equity, domestic fixed-income, foreign equity and foreign
 fixed-income securities. The Portfolio will pursue its objective by investing
 a substantial portion of its assets in shares of the Trust's other investment
 portfolios and unaffiliated investment companies.     
 The EQUITY INDEX PORTFOLIO seeks to provide investment results approximating
 the aggregate price and dividend performance of the securities included in
 the Standard & Poor's 500 Composite Stock Price Index (the "S&P Index") by
 investing substantially all of its assets in securities comprising the S&P
 Index.
 The DIVERSIFIED GROWTH PORTFOLIO seeks to provide long-term capital
 appreciation with income a secondary consideration by investing principally
 in common and preferred stocks and securities convertible into common stock
 of growth companies.
 The FOCUSED GROWTH PORTFOLIO seeks to provide long-term capital appreciation
 by investing primarily in common stocks of growth companies. Any income
 received is incidental to the objective of capital appreciation.
 The SMALL COMPANY INDEX PORTFOLIO seeks to provide investment results
 approximating the aggregate price and dividend performance of the securities
 included in the Russell 2000 Small Stock Index (the "Russell Index") by
 investing substantially all of its assets in securities represented in the

 approximating the aggregate price and dividend performance of the securities
 in the Morgan Stanley Capital International (MSCI) Europe, Australia and Far
 East Index (the "EAFE Index").
 The INTERNATIONAL GROWTH PORTFOLIO seeks to provide long-term capital
 appreciation by investing principally in common and preferred stocks and
 securities convertible into common stock of foreign issuers. Any income
 received is incidental to the objective of capital appreciation.

                              SUMMARY OF EXPENSES
   
The following table sets forth certain information regarding the shareholder
transaction expenses imposed by the Trust and the annualized operating
expenses of the Portfolios (except the Intermediate Bond, Global Asset and
International Equity Index Portfolios) incurred during the Trust's last fiscal
year, and the estimated annualized operating expenses that the Intermediate
Bond, Global Asset and International Equity Index Portfolios expect to incur
during the current fiscal year. Hypothetical examples based on the table are
also shown. Investors should note that shares of each Portfolio have been
classified into four separate classes, Class A, B, C and D Shares. Each class
is distinguished by the level of administrative support and transfer agency
services provided. Class A, B, C and D Shares represent pro rata interests in
a Portfolio except that different shareholder servicing fees and transfer
agency fees are payable by Class A, B, C and D Shares. See "Trust
Information--Shareholder Servicing Plan."     
   
The Global Asset Portfolio may invest up to 100% of its assets in shares of
other investment companies. Accordingly, an investor in the Global Asset
Portfolio will bear a proportionate share of the expenses of such underlying
funds in addition to the expenses of the Portfolio. The information on
shareholder transaction expenses and estimated annual operating expenses in
the table below relates solely to the Global Asset Portfolio and does not
include the expenses associated with the Portfolio's investments in other
investment companies.

The Global Asset Portfolio will invest a substantial portion of its assets in
Class A Shares of other investment portfolios of the Trust (collectively, the
"Benchmark Portfolios"), including the Trust's money market portfolios, the
Government Select Portfolio, Government Portfolio, Diversified Assets
Portfolio, and Tax-Exempt Portfolio which are offered under a separate
prospectus. The total expense ratios of Class A Shares of the equity and fixed
income Benchmark Portfolios are set forth above. Based on a hypothetical mix
of Benchmark Portfolio shares that the Global Asset Portfolio may hold under
current market conditions, the weighted average expense ratio associated with
the Portfolio's investment in Class A Shares of the Benchmark Portfolios would
be 0.34%, and excludes the effect of any transaction fee associated with
investment in a Benchmark Portfolio. The actual allocation of the Global Asset
Portfolio's assets among the Benchmark Portfolios will vary with changing
market conditions. In addition, the weighted average expense ratio of the
Portfolio's investments in the Benchmark Portfolios does not reflect the
expenses associated with the Portfolio's investments in unaffiliated
investment companies, which could increase or decrease this weighted average
expense ratio. Based on the foregoing, the estimated cumulative total expense
ratio of Class A, B, C and D Shares of the Global Asset Portfolio, including
both the expenses associated with the Portfolio and the expenses relating to
its investments in other Benchmark Portfolios, would be .80%, .94%, 1.04% and
1.19%, respectively.

 Based on the cumulative
 total expense ratios
 set forth in the
 preceding paragraph,
 you would pay the
 following expenses on a
 hypothetical $1,000
 investment in the
 Global Asset Portfolio,
 assuming a 5% annual
 total return and
 redemption at the end
 of each time period:
 One Year...............  $8 $10 $11 $12

(1) For the fiscal year ending November 30, 1997, Northern voluntarily reduced
    its advisory fee for the U.S. Government Securities, Short-Intermediate
    Bond, U.S. Treasury Index, Bond, Intermediate Bond, International Bond,
    Balanced, Equity Index, Diversified Growth, Focused Growth, Small Company
    Index, International Equity Index, and International Growth Portfolios.
    Advisory fees are otherwise payable at the annual rate of .60%, .60%,
    .40%, .60%, .60%, .90%, .80%, .30%, .80%, 1.10%, .40%, .50% and 1.00%,
    respectively, of the Portfolios' respective average daily net assets. In
    addition, Northern has voluntarily agreed to reduce its advisory fee for
    the Global Asset Portfolio to .35% of the Portfolio's average daily net
    assets for the current fiscal year (advisory fees are otherwise payable at
    the annual rate of .60% of the Global Asset Portfolio's average daily net
    assets).     
   
(2) The Trust has adopted a Shareholder Servicing Plan pursuant to which the
    Trust may enter into agreements with Institutions or other financial
    intermediaries under which they render (or arrange to have rendered)
    certain shareholder administrative support services for     
 
                                       7
<PAGE>
 
     
  their Customers or other Investors who beneficially own Class B, C and D
  Shares in return for a fee ("Servicing Fee") of up to .10%, .15%, and .25%,
  respectively, per annum of the value of each Portfolio's outstanding Class
  B, C and D Shares, respectively. The Trust also allocates transfer agency
  fees, which are attributable to the Class A, B, C and D Shares in a
  Portfolio, separately to such Shares, as reflected in the table. For further
  information, see "Investment Adviser, Transfer Agent and Custodian" and
  "Shareholder Servicing Plan" under the heading "Trust Information" in this
  Prospectus.     
   
(3) For the fiscal period December 1, 1996 through April 30, 1997, Goldman
    Sachs reduced its administration fee (otherwise payable with respect to
    each Portfolio during such period at the annual rate of .25% of the first
    $100 million, .15% of the next $200 million, .075% of the next $450
    million and .05% of any excess over $750 million of the Portfolio's
    average daily net assets) to .10% of each Portfolio's average daily net
    assets. For the fiscal period May 1, 1997 through November 30, 1997,
    Goldman Sachs was entitled to an administration fee from each Portfolio at
    an annual rate of .15% of the average daily net assets of each of the
    International Bond, International Equity Index and International Growth
    Portfolios and .10% of the average daily net assets of each other
    Portfolio. In addition, during the fiscal year ended November 30, 1997
    Goldman Sachs reimbursed each Portfolio's expenses (including the fees
    payable to Goldman Sachs as administrator, but excluding the fees payable
    to Northern for its duties as adviser and transfer agent, servicing fees
    and certain extraordinary expenses) which exceeded on an annualized basis
    .25% of the International Bond, International Equity Index and
    International Growth Portfolios' average daily net assets and .10% of each
    other Portfolio's average daily net assets for such period. The expense
    information in the table has, accordingly, been presented to reflect these
    fee reductions and expense reimbursements (estimated in the case of the
    Intermediate Bond, Global Asset and International Equity Index
    Portfolios).     
   
(4) Without the undertakings of Northern and Goldman Sachs, and had all
    classes of shares been outstanding during the year ending November 30,
    1997, "Other Expenses" in the foregoing table would have been as follows:
    U.S. Government Securities Portfolio--.24%; Short-Intermediate Bond
    Portfolio--.20%; U.S. Treasury Index Portfolio--.41%; Bond Portfolio--
    .16%; International Bond Portfolio--.61%; Balanced Portfolio--.30%; Equity
    Index Portfolio--.15%; Diversified Growth Portfolio--.22%; Focused Growth
    Portfolio--.23%; Small Company Index Portfolio--.27%; and International
    Growth Portfolio--.36%; and the total annual operating expenses would have
    been as follows for Class A, B, C and D Shares, respectively: U.S.
    Government Securities Portfolio--.85%, .99%, 1.09% and 1.24%; Short-
    Intermediate Bond Portfolio--.81%, .95%, 1.05% and 1.20%; U.S. Treasury
    Index Portfolio--.82%, .96%, 1.06% and 1.21%; Bond Portfolio--.77%, .91%,
    1.01% and 1.16%; International Bond Portfolio--1.52%, 1.66%, 1.76% and
    1.91%; Balanced Portfolio--1.11%, 1.25%, 1.35% and 1.50%; Equity Index
    Portfolio--.46%, .60%, .70% and .85%; Diversified Growth Portfolio--1.03%,
    1.17%, 1.27% and 1.42%; Focused Growth Portfolio--1.34%, 1.48%, 1.58% and
    1.73%; Small Company Index Portfolio--.68%, .82%, .92% and 1.07%; and
    International Growth Portfolio--1.37%, 1.51%, 1.61% and 1.76%, based on
    actual expenses incurred during the fiscal year ended November 30, 1997.
    Without the undertakings of Northern and Goldman Sachs, it is estimated
    that "Other Expenses" would be .57% for the Intermediate Bond Portfolio,
    .43% for the Global Asset Portfolio and .39% for the International Equity
    Index Portfolio, and total annual operating expenses for each of the
    Intermediate Bond, Global Asset and International Equity Index Portfolio's
    Class A, B, C and D Shares would be 1.18%, 1.32%, 1.42% and 1.57%; 1.04%,
    1.18%, 1.28% and 1.43%; and .90%, 1.04%, 1.14% and 1.29%, respectively,
    for the current fiscal year. See note (7) below. For a more complete
    description of the Portfolios' expenses, see "Trust Information" in this
    Prospectus.     
   
(5) The actual expense ratios reflected in the above table for each class of
    the Equity Index, Diversified Growth, Focused Growth and Small Company
    Index Portfolios include interest expense of .01%, associated with
    temporary borrowings. Interest expense is not subject to voluntary expense
    limitations. Had the Portfolios not experienced such temporary borrowings,
    the total annual operating expense ratios would have been as follows:
    Equity Index Class A, B, C and D Shares--.21%, .35%, .45% and .60%,
    respectively; Diversified Growth Class A, B, C and D Shares--.66%, .80%,
    .90% and 1.05%, respectively; Focused Growth Class A, B, C and D Shares--
    .91%, 1.05%, 1.15% and 1.30%, respectively; and Small Company Index Class
    A, B, C and D Shares--.31%, .45%, .55% and .70%, respectively. Whether
    such borrowings will occur in any given year and the actual amount of such
    borrowings is difficult to predict.     
   
(6) To prevent the Small Company Index Portfolio and International Equity
    Index Portfolio from being adversely affected by the transaction costs
    associated with share purchases, the Portfolios will sell shares at a
    price equal to the net asset value of the shares plus an additional
    transaction fee equal to .50% and 1.00%, respectively, of such value. Such
    amounts are not sales charges, but are retained by the Portfolios for the
    benefit of all shareholders (see "Investment Information--Small Company
    Index Portfolio," "Investment Information--International Equity Index
    Portfolio," "Investing--Purchase of Shares" and "Investing--Redemption of
    Shares"). The Global Asset Portfolio may invest in these Portfolios and
    will be subject to the respective transaction fees.     
 
(7) The costs and expenses included in the table and hypothetical example
    above are based on estimated fees and expenses for the current fiscal year
    and should not be considered as representative of past or future expenses.
    Actual fees and expenses may be greater or less than those indicated.

                            INVESTMENT INFORMATION
 
INTRODUCTION
   
The Trust is an open-end management investment company registered under the
Investment Company Act of 1940 (the "1940 Act"). Each Portfolio consists of a
separate pool of assets with separate investment objectives and policies, as
described below. Each Portfolio, other than the International Bond Portfolio,
is classified as a diversified investment company. The International Bond
Portfolio is classified as a non-diversified investment company. Shares of
each Portfolio have been classified into four classes--Class A Shares, Class B
Shares, Class C Shares and Class D Shares. Northern serves as investment
adviser to all Portfolios other than the U.S. Treasury Index, Equity Index,
Small Company Index and International Equity Index Portfolios, which are
advised by NTQA. Northern serves as the transfer agent and custodian for all
Portfolios. Goldman Sachs serves as distributor and administrator. With the
exception of the Intermediate Bond Portfolio and the Global Asset Portfolio,
the investment objective of a Portfolio may not be changed without the vote of
the majority of the outstanding shares of the particular Portfolio. Except as
expressly noted below, however, each Portfolio's investment policies may be
changed without a vote of shareholders. The U.S. Government Securities, Short-
Intermediate Bond, U.S. Treasury Index, Bond, Intermediate Bond and
International Bond Portfolios may collectively be referred to as the "Fixed
Income Portfolios," and the Balanced, Global Asset, Equity Index, Diversified
Growth, Focused Growth, Small Company Index, International Equity Index and
International Growth Portfolios may collectively be referred to as the "Equity
Portfolios."     
 
U.S. GOVERNMENT SECURITIES PORTFOLIO
 
The U.S. Government Portfolio's investment objective is to seek to maximize
total return with minimal reasonable risk. In pursuing its investment
objective, the U.S. Government Securities Portfolio will, under normal market
conditions, invest at least 65% of its total assets in a broad range of
securities issued or guaranteed by the U.S. Government, its agencies and
instrumentalities and repurchase agreements relating to such securities,
including mortgage-related securities issued by agencies of the U.S.
Government. The Portfolio's dollar-weighted average maturity will be between
one and five years.
 
The Portfolio may enter into interest rate swaps and may invest in options and
futures contracts and related options. The Portfolio may also invest in
certain short-term fixed income securities as cash reserves. See "Description
of Securities and Common Investment Techniques" below for more information.
 
SHORT-INTERMEDIATE BOND PORTFOLIO
   
The investment objective of the Short-Intermediate Bond Portfolio is to seek
to maximize total return consistent with reasonable risk. In pursuing its
investment objective, the Short-Intermediate Bond Portfolio invests in a broad
range of bonds and other fixed income securities. The Portfolio's dollar-
weighted average maturity will be between two and five years. The Portfolio
will invest primarily in fixed income securities of all types and in any
proportion that generally are investment grade at the time of purchase, and
may include obligations of the U.S. Government, its agencies or
instrumentalities, obligations of foreign governments, obligations of U.S. and
foreign corporations and obligations of U.S. and foreign banks. The
obligations of a foreign issuer will not be purchased by the Short-
Intermediate Bond Portfolio if, as a result of the purchase, more than 20% of
the total assets of the Portfolio will be invested in the obligations of
issuers within a single foreign country. The Portfolio     
 
                                      32
<PAGE>
 
may also invest up to 10% of its total assets in non-investment grade
securities. Under normal market conditions, at least 65% of the Portfolio's
total assets will be invested in bonds, debentures, mortgage and other asset-
related securities, zero coupon bonds and convertible debentures. The
Portfolio may also invest in short-term notes, bills, commercial paper and
certificates of deposit.
 
The Portfolio may enter into forward currency contracts and interest rate
swaps and may invest in options and futures contracts and related options. The
Portfolio may also invest in certain short-term fixed income securities as
cash reserves. See "Description of Securities and Common Investment
Techniques" below for more information.
 
U.S. TREASURY INDEX PORTFOLIO
   
The investment objective of the U.S. Treasury Index Portfolio is to seek to
provide investment results approximating the performance of the Lehman Index.
In pursuing its investment objective, the U.S. Treasury Index Portfolio under
normal conditions will invest directly or indirectly at least 80% of its total
assets in a representative sample of the U.S. Treasury obligations included in
the Lehman Index. The Lehman Index is comprised of all public obligations of
the U.S. Treasury, excluding flower bonds and foreign-targeted issues. The
Investment Adviser will select securities for the Portfolio based on their
expected contribution to its overall duration, quality and total return as
compared to the Lehman Index and comparable investment characteristics. Lehman
Brothers ("Lehman") makes no representation or warranty, implied or express,
to purchasers of Portfolio units or any member of the public regarding the
advisability of investing in the Portfolio or the ability of the Lehman Index
to track general bond market performance.     
   
The Portfolio is managed through the use of a "passive" or "indexing"
investment approach, which attempts to duplicate the investment composition
and performance of the Lehman Index through statistical procedures. As a
result, the Investment Adviser does not employ traditional methods of fund
investment management, such as selecting securities on the basis of economic,
financial and market analysis.     
 
The Portfolio may invest in options and futures contracts and related options.
The Portfolio may also invest in certain short-term fixed income securities as
cash reserves. See "Description of Securities and Common Investment
Techniques" and "Special Risks and Other Considerations" below for more
information.
 
BOND PORTFOLIO
 
The investment objective of the Bond Portfolio is to seek to maximize total
return consistent with reasonable risk. In pursuing its investment objective,
the Bond Portfolio invests in a broad range of bonds and other fixed income
securities. The Portfolio's dollar-weighted average maturity will range
between five and fifteen years.
   
The Portfolio will invest primarily in fixed income securities of all types
and in any proportion that generally are investment grade at the time of
purchase, and may include obligations of the U.S. Government, its agencies or
instrumentalities, obligations of foreign, state and local governments,
obligations of U.S. and foreign corporations and obligations of U.S. and
foreign banks. The obligations of a foreign issuer will not be purchased by
the Bond Portfolio if, as a result of the purchase, more than 20% of the total
assets of the Portfolio will be invested in the obligations of issuers within
a single foreign country. The Portfolio may also invest up to 10% of its total
assets in non-investment grade securities. Under normal market conditions, at
least 65% of the Portfolio's     
 
                                      33
<PAGE>
 
total assets will be invested in bonds, debentures, mortgage and other asset-
related securities, zero coupon bonds and convertible debentures. The
Portfolio may also invest in short-term notes, bills, commercial paper and
certificates of deposits.
 
The Portfolio may enter into forward currency contracts and interest rate
swaps and may invest in options and futures contracts and related options. The
Portfolio may also invest in certain short-term fixed income securities as
cash reserves. See "Description of Securities and Common Investment
Techniques" below for more information.
 
INTERMEDIATE BOND PORTFOLIO
   
The investment objective of the Intermediate Bond Portfolio is to seek to
maximize total return consistent with reasonable risk. In pursuing its
investment objective, the Intermediate Bond Portfolio invests in a broad range
of bonds and other fixed income securities. The Portfolio's dollar-weighted
average maturity will range between three and ten years. The Portfolio will
invest primarily in fixed income securities of all types and in any proportion
that generally are investment grade at the time of purchase, and may include
obligations of the U.S. Government, its agencies or instrumentalities,
obligations of foreign, state and local governments, obligations of U.S. and
foreign corporations and obligations of U.S. and foreign banks. The Portfolio
may invest up to 25% of its total assets in foreign securities, including up
to 15% of its total assets in securities of issuers in countries with emerging
economies or securities markets. The obligations of a foreign issuer will not
be purchased by the Portfolio if, as a result of the purchase, more than 20%
of the total assets of the Portfolio will be invested in the obligations of
issuers within a single foreign country. The Portfolio may also invest up to
10% of its total assets in non-investment grade securities. Under normal
market conditions, at least 65% of the Portfolio's total assets will be
invested in bonds, debentures, mortgage and other asset-related securities,
zero coupon bonds and convertible debentures. The Portfolio may also invest in
short-term notes, bills, commercial paper and certificates of deposits.     
 
The Portfolio may enter into forward currency contracts and interest rate
swaps and may invest in options and futures contracts and related options. The
Portfolio may also invest in certain short-term fixed income securities as
cash reserves. See "Description of Securities and Common Investment
Techniques" below for more information.
 
INTERNATIONAL BOND PORTFOLIO
 
The investment objective of the International Bond Portfolio is to seek to
maximize total return consistent with reasonable risk. In pursuing its
investment objective, the International Bond Portfolio invests primarily (at
least 65% of its total assets under normal market conditions) in a broad range
of bonds and other fixed income securities of foreign issuers. The Portfolio's
dollar-weighted average maturity will range between three and eleven years.
 
The Portfolio will be invested at all times in the securities of issuers
located in at least three different foreign countries. These countries may
include, but are not limited to: Argentina, Australia, Austria, Belgium,
Brazil, Canada, Chile, Colombia, Denmark, Finland, France, Germany, Greece,
Hong Kong, Hungary, Indonesia, Ireland, Israel, Italy, Japan, Luxembourg,
Malaysia, Mexico, the Netherlands, New Zealand, Norway, Peru, the Philippines,
Poland, Portugal, Singapore, South Africa, South Korea, Spain, Sweden,
Switzerland, Taiwan,
 
                                      34
<PAGE>
 
Thailand, Turkey, the United Kingdom and Venezuela. Criteria for determining
the appropriate distribution of investments among various countries and
regions include prospects for relative economic growth, expected levels of
inflation, government policies influencing business conditions, the outlook
for currency relationships, and the range of investment opportunities
available to international investors.
   
The Portfolio will invest primarily in fixed income securities of all types as
set forth below and in any proportion that generally are investment grade at
the time of purchase, although a portion of its assets may be invested in non-
investment grade securities. These securities may include obligations of
foreign governments, their agencies, instrumentalities and political
subdivisions; supranational organizations (e.g., European Investment Bank,
Inter-American Development Bank and the World Bank); and foreign corporations
and banks. These obligations may consist of bonds, debentures, mortgage and
other asset-related securities, zero coupon bonds and convertible debentures.
The Portfolio may also invest in obligations of the U.S. Government, its
agencies and instrumentalities (including repurchase agreements collateralized
by such obligations) and of U.S. corporations and banks as well as short-term
notes, bills, commercial paper and certificates of deposit. It is expected
that during the current fiscal year a substantial portion of the Portfolio's
assets will be invested in foreign governmental obligations.     
 
The International Bond Portfolio is classified as a non-diversified portfolio
under the 1940 Act. Investment return on a non-diversified portfolio typically
is dependent upon the performance of the securities of a smaller number of
issuers relative to the number held in a diversified portfolio. Consequently,
the change in value of any one security may affect the overall value of a non-
diversified portfolio more than it would a diversified portfolio.
 
The Portfolio may enter into forward currency exchange contracts and currency
and interest rate swaps and utilize options and futures contracts. Pending
investment, as a temporary defensive measure and to meet anticipated
redemption requests, the Portfolio may invest, in accordance with its
investment policies, in various short-term obligations, such as U.S.
Government obligations, high quality money market investments and repurchase
agreements. See "Description of Securities and Common Investment Techniques"
and "Special Risks and Other Considerations" below for more information.
 
BALANCED PORTFOLIO
 
The investment objective of the Balanced Portfolio is to seek to provide long-
term capital appreciation and current income. The Portfolio will invest at
least 25% of the value of its total assets in fixed income senior securities
and no more than 75% in equity securities under normal market conditions. The
actual percentage of assets invested in equity and fixed income securities
will vary from time to time, depending upon Northern's judgment as to general
market and economic conditions, trends and yields, interest rates and changes
in fiscal and monetary policies. The Portfolio reserves the right to hold as a
temporary defensive measure up to 100% of its total assets in cash and short-
term obligations (having remaining maturities of 18 months or less) at such
times and in such proportions as, in the opinion of Northern, is warranted.
For purposes of determining the percentages of the Portfolio's assets that are
invested in equity and fixed income securities, respectively, only that
portion of the value of convertible securities attributable to their fixed
income characteristics will be deemed to be a fixed income investment.
   
The Portfolio may invest in common and preferred stocks, securities
convertible into common stock and other types of equity or equity-related
securities ("equity securities"). The Portfolio selects equity securities
based on such factors as growth of sales, return on equity, growth and
consistency of earnings, financial condition, market     
 
                                      35
<PAGE>
 
share, product leadership and other investment criteria. The Portfolio will
normally limit its equity investments to the securities of companies which
together with their predecessors have been in continuous operation for at
least five years and have stock market capitalization in excess of $200
million. The Portfolio may also purchase warrants and rights which entitle the
holder to buy equity securities at a specified price for a specified period of
time.
   
The Portfolio will invest in fixed income securities of all types as set forth
below and in any proportions that generally are investment-grade at the time
of purchase. These securities may include bonds, debentures, mortgage and
other asset-related securities, zero coupon bonds, convertible debentures, and
other obligations issued by the U.S. Government, its agencies or
instrumentalities, foreign governments, U.S. and foreign corporations and U.S.
and foreign banks. The Portfolio may also purchase bonds that are issued in
tandem with warrants which entitle the holder to purchase certain common stock
at a specified price during a specified period of time. The Portfolio may also
invest in short-term notes, bills, commercial paper and certificates of
deposit. The dollar-weighted average maturity of the fixed income portion of
the Portfolio will, under normal market conditions, range between two and ten
years.     
 
The Portfolio may also enter into forward currency contracts and utilize
options and futures contracts and related options. Pending investment, as a
temporary defensive measure and to meet anticipated redemption requests, the
Portfolio may also invest in various short-term obligations. See "Description
of Securities and Common Investment Techniques" and "Special Risks and Other
Considerations" below for more information.
 
GLOBAL ASSET PORTFOLIO
   
The investment objective of the Global Asset Portfolio is to seek to provide
long-term capital appreciation and current income. In pursuing its investment
objective, the Portfolio allocates its assets for investment among four market
segments: domestic equity securities, domestic fixed-income securities,
foreign equity securities and foreign fixed-income securities. To achieve this
allocation, the Portfolio will generally invest a substantial portion (up to
100%) of its assets in shares of one or more other investment portfolios of
the Trust ("Benchmark Portfolios") which invest in such segments. By investing
in shares of the Benchmark Portfolios, the Global Asset Portfolio expects to
be able to achieve greater diversification within these market segments than
through direct investments in individual securities. The Portfolio may also
make direct investments in domestic and foreign equity or fixed-income
securities or purchase shares of unaffiliated investment companies, including
World Equity Benchmark SharesSM issued by The Foreign Fund, Inc. ("WEBS")
whenever it is deemed advisable to do so in order to achieve the desired
exposure to any of the four market segments and to achieve the Portfolio's
investment objective. See "International Equity Index Portfolio" below for
more information on WEBS. The Portfolio's investments in unaffiliated
investment companies will be limited in accordance with the provisions of the
1940 Act.     
 
Northern will allocate the assets of the Portfolio among the market segments
identified above, and, within each segment, among the various Benchmark
Portfolios, unaffiliated investment companies and individual securities.
 
Under normal market conditions, it is anticipated that the Portfolio will
invest at least 20% of its assets directly or indirectly in fixed income
senior securities, and at least 65% of its total assets directly or indirectly
in securities of issuers in at least three different countries.
 
                                      36
<PAGE>
 
Subject to the foregoing, the Portfolio may allocate 0%-100% of its assets to
any market segment. The table below identifies the Benchmark Portfolios
represented in each market segment:

      Foreign Fixed Income                International Bond Portfolio
</TABLE>    
 
In making decisions regarding the appropriate exposure to each segment,
Northern will consider general market and economic conditions and factors such
as the relative market capitalization weightings of these segments, stock and
bond index price changes, fluctuations in interest and currency exchange
rates, and political events which may impact market performance for specific
countries or regions, as well as the liquidity needs of the Portfolio. By
allocating its investments in this manner, Northern believes that the
Portfolio will not be exposed to the same degree of market risk as a portfolio
which, for example, invests in only one market segment.
   
In allocating the Portfolio's assets among the Benchmark Portfolios and
unaffiliated investment companies, Northern will consider their investment
objectives and policies, expenses, performance history and other factors it
deems relevant. The allocation of the Portfolio's assets among investment
companies may be changed from time to time without the approval of the
Portfolio's shareholders. Although the Portfolio may invest in each Benchmark
Portfolio, it is expected that the Portfolio will normally be invested in only
some of the Benchmark Portfolios at any particular time and will most
typically select from among the Equity Index, Diversified Growth, Focused
Growth, Small Company Index, Bond, Short-Intermediate Bond, Intermediate Bond,
International Equity Index, International Growth and International Bond
Portfolios. The Portfolio's investment in any particular Benchmark Portfolio
may exceed 25% of the Portfolio's assets and it is expected that such a
concentration may most typically occur with respect to investments in the
Equity Index, Diversified Growth, Focused Growth and Bond Portfolios.     
   
In addition to its investments in other investment companies, the Portfolio
may make direct investments in equity securities based on such factors as
growth of sales, return on equity, growth and consistency of earnings,
financial     
 
                                      37
<PAGE>
 
   
condition, market share, product leadership and other investment criteria. In
addition, the Portfolio may purchase warrants and rights which entitle the
holder to buy equity securities at a specified price for a specified period of
time. The Portfolio may also invest directly in fixed income securities of all
types as set forth below and in any proportions that generally are investment
grade at the time of purchase, and may purchase bonds that are issued in
tandem with warrants which entitle the holder to purchase certain common
stocks at a specified price during a specified period of time. The Portfolio
may also invest in short-term notes, bills, commercial paper and certificates
of deposit.     
   
The Portfolio may enter into forward currency contracts and utilize options
and future contracts and related options. Pending investment, as a temporary
defensive measure and to meet anticipated redemption requests, the Portfolio
may also invest in shares of money market funds or directly in other short-
term obligations. See "Description of Securities and Common Investment
Techniques" and "Special Risks and Other Considerations" below for more
information.     
   
Prospective investors should note that the Trust has filed an application with
the Securities and Exchange Commission (the "SEC") requesting an exemption
from certain provisions of the 1940 Act to allow the Portfolio to conduct its
investment operations as described in this Prospectus. As of the date of this
Prospectus, the requested exemption had not been granted, and there is no
assurance that it will be. No shares of the Portfolio will be sold unless and
until the requested exemption is granted.     
 
EQUITY INDEX PORTFOLIO
   
The investment objective of the Equity Index Portfolio is to seek to provide
investment results approximating the aggregate price and dividend performance
of the securities included in the S&P Index. Under normal market conditions
the Portfolio will invest directly or indirectly at least 80% of the
Portfolio's total assets in the common stocks of the companies that constitute
the S&P Index, in approximately the same proportions as they are represented
in the S&P Index. The S&P Index is a market value-weighted index consisting of
500 common stocks which are traded on the New York Stock Exchange, American
Stock Exchange and the NASDAQ National Market System and selected by Standard
& Poor's Corporation ("S&P") through a detailed screening process starting on
a macro-economic level and working toward a micro-economic level dealing with
company-specific information such as market value, industry group
classification, capitalization and trading activity. S&P's primary objective
for the S&P Index is to be the performance benchmark for the U.S. equity
markets. The companies chosen for inclusion in the S&P Index tend to be
leaders in important industries within the U.S. economy. However, companies
are not selected by S&P for inclusion because they are expected to have
superior stock price performance relative to the market in general or other
stocks in particular. S&P makes no representation or warranty, implied or
express, to purchasers of Portfolio shares or any member of the public
regarding the advisability of investing in the Portfolio or the ability of the
S&P Index to track general stock market performance.     
   
The Equity Index Portfolio is managed through the use of a "passive" or
"indexing" investment approach, which attempts to duplicate the investment
composition and performance of the S&P Index through statistical procedures.
As a result, the Investment Adviser does not employ traditional methods of
fund investment management for this Portfolio, such as selecting securities on
the basis of economic, financial and market analysis.     
 
The Portfolio may invest in options and futures contracts and related options.
The Portfolio may also invest in certain short-term fixed income securities as
cash reserves. However, it is not anticipated that the Portfolio will
 
                                      38
<PAGE>
 
invest in cash reserves, options or futures contracts and related options as
part of a temporary defensive strategy such as lowering its investment in
common stocks to protect against potential stock market declines. See
"Description of Securities and Common Investment Techniques" and "Special
Risks and Other Considerations" below for more information.
 
DIVERSIFIED GROWTH PORTFOLIO
 
The investment objective of the Diversified Growth Portfolio is to seek to
provide long-term capital appreciation with income a secondary consideration.
The Portfolio invests principally in common and preferred stocks and
securities convertible into common stock. The Portfolio will, under normal
market conditions, invest at least 65% of its assets in equity securities of
domestic and foreign issuers. The Portfolio selects investments based on such
factors as growth of sales, return on equity, growth and consistency of
earnings, financial condition, market share, product leadership and other
investment criteria. The Portfolio may also purchase warrants and rights which
entitle the holder to buy equity securities at a specific price for a specific
period of time.
 
The Portfolio may also enter into forward currency contracts and utilize
options and futures contracts and related options. Pending investment, as a
temporary defensive measure and to meet anticipated redemption requests, the
Portfolio may also invest in various short-term obligations. See "Description
of Securities and Common Investment Techniques" below for more information.
 
FOCUSED GROWTH PORTFOLIO
   
The investment objective of the Focused Growth Portfolio is to seek to provide
long-term capital appreciation. Any income received is incidental to the
objective of capital appreciation. The Portfolio invests in common and
preferred stocks and securities convertible into common stock of companies
believed by Northern to have superior quality and growth characteristics.
Under normal market conditions at least 65% of the Portfolio's total assets
will be invested in equity securities of domestic and foreign issuers. The
Portfolio selects equity securities based on such factors as growth of sales,
return on equity, growth and consistency of earnings, financial condition,
market share, product leadership and other investment criteria. In attempting
to achieve the Portfolio's investment objective, Northern may, from time to
time, emphasize particular companies or market segments, subject to the
Portfolio's policies on security and industry diversification as described
under "Investment Restrictions." Companies in which the Portfolio invests
often retain their earnings to finance current and future growth and generally
pay little or no dividends. The Portfolio may also purchase warrants and
rights which entitle the holder to buy equity securities at a specific price
for a specific period of time. The Portfolio intends to invest in the
securities of companies which together with their predecessors have been in
continuous operation for at least five years and have stock market
capitalization in excess of $200 million.     
 
The Portfolio may also enter into forward currency contracts and utilize
options and futures contracts and related options. Pending investment, as a
temporary defensive measure and to meet anticipated redemption requests, the
Portfolio may also invest in various short-term obligations. See "Description
of Securities and Common Investment Techniques" below for more information.
 
SMALL COMPANY INDEX PORTFOLIO
 
The investment objective of the Small Company Index Portfolio is to seek to
provide investment results approximating the aggregate price and dividend
performance of the securities included in the Russell Index.
 
                                      39
<PAGE>
 
   
Under normal market conditions, the Portfolio will invest directly or
indirectly at least 80% of its total assets in the stocks included in the
Russell Index. The Russell Index is a market value-weighted index comprised of
the stocks of the smallest 2,000 companies in the Russell 3000 Index which is
comprised of the stocks of the 3,000 largest U.S. domiciled companies (based
on market capitalization) that represent approximately 83% of the investable
U.S. equity markets. Because of its emphasis on the smallest 2,000 companies,
the Russell Index represents approximately 10% of the total market
capitalization of the Russell 3000 Index. As of January 31, 1998, the average
market capitalization of the companies included in the Russell Index, adjusted
for cross-holdings, was approximately $570 million. The Russell Index is
reconstituted annually to reflect changes in market capitalization. The
primary criteria used by Frank Russell & Company ("Russell") to determine the
initial list of securities eligible for inclusion in the Russell 3000 Index
(and, accordingly, the Russell Index) is total market capitalization adjusted
for large private holdings and cross-ownership. However, companies are not
selected by Russell for inclusion in the Russell Index because they are
expected to have superior stock price performance relative to the stock market
in general or other stocks in particular. Russell makes no representation or
warranty, implied or express, to purchasers of Portfolio shares or any member
of the public regarding the advisability of investing in the Portfolio or the
ability of the Russell Index to track general market performance of small
capitalization stocks.     
 
The Portfolio will be constructed to have aggregate investment characteristics
similar to those of the Russell Index as a whole. The Portfolio will invest in
securities which will be selected on the basis of such factors as
market capitalization, beta, industry sectors and economic factors. The number
of issues included will be a function of the Portfolio's liquidity and size.
The Portfolio will be restructured annually when the Russell Index is
reconstituted.
 
It should be noted that small companies in which the Portfolio may invest may
have limited product lines, markets, or financial resources, or may be
dependent upon a small management group, and their securities may be subject
to more abrupt or erratic market movements than larger, more established
companies, both because their securities typically are traded in lower volume
and because the issuers typically are subject to a greater degree of changes
in their earnings and prospects.
   
The Small Company Index Portfolio is managed through the use of a "passive" or
"indexing" investment approach, which attempts to duplicate the investment
composition and performance of the Russell Index through statistical
procedures. As a result, the Investment Adviser does not employ traditional
methods of fund investment management, such as selecting securities on the
basis of economic, financial and market analysis.     
 
The Portfolio may invest in options and futures contracts and related options.
The Portfolio may also invest in certain short-term fixed income securities as
cash reserves. However, it is not anticipated that the Portfolio will invest
in cash reserves, options or futures contracts and related options as part of
a temporary defensive strategy such as lowering its investment in common
stocks to protect against potential stock market declines. See "Description of
Securities and Common Investment Techniques" and "Special Risks and Other
Considerations" below for more information.
   
The Portfolio requires the payment of an additional transaction fee on the
purchase of shares equal to 0.50% of the dollar amount invested. See
"Investing--Purchase of Shares" and "Investing--Redemption of Shares" below
for more information.

INTERNATIONAL EQUITY INDEX PORTFOLIO
   
The investment objective of the International Equity Index Portfolio is to
seek to provide investment results approximating the aggregate price and
dividend performance of the securities in the EAFE Index. The EAFE Index is a
broad-based market capitalization weighted index currently composed of more
than 1,100 securities in twenty countries. Fourteen European countries
(Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the
Netherlands, Norway, Spain, Sweden, Switzerland and the United Kingdom)
constitute approximately 55% of the EAFE Index. Six Asian/Pacific countries
(Australia, Hong Kong, Japan, Malaysia, New Zealand and Singapore) account for
the remaining 45%. Under normal market conditions, the Portfolio will invest,
directly or indirectly, at least 65% of its total assets in the securities
that constitute the EAFE Index.     
   
The International Equity Index Portfolio is managed through the use of a
"passive" or "indexing" investment approach, which attempts to duplicate the
investment composition and performance of the EAFE Index through statistical
procedures. As a result, the Investment Adviser does not employ traditional
methods of fund investment management for this Portfolio, such as selecting
securities on the basis of economic, financial and market analysis. The
Portfolio will be constructed to have aggregate investment characteristics
similar to those of the EAFE Index as a whole. The proportion of assets
invested in each country will approximate the weight of each country in the
EAFE Index, and the Portfolio will invest in securities selected on the basis
of such factors as country exposure, market capitalization, beta, industry
sectors and economic factors. The number of issuers included will be a
function of the Portfolio's liquidity and size.     
 
Because the Portfolio will invest in countries according to their weights in
the EAFE Index, more than 25% of the Portfolio's assets may be invested in a
single country. In particular, Japan currently constitutes approximately one-
third of the EAFE Index and would comprise a similar percentage of the
Portfolio's assets, making the Portfolio's performance more dependent upon the
political and economic circumstances in Japan than a portfolio that is more
widely diversified among the issuers in different countries.
   
It is anticipated that, in seeking to achieve its investment objective, the
Portfolio may invest a significant portion (i.e., more than 10%) of its assets
in instruments such as World Equity Benchmark Shares SM issued by The Foreign
Fund, Inc. ("WEBS") and similar securities of other issuers. Absent unusual
circumstances, these investments are not expected to exceed 35% of the
Portfolio's assets during the current fiscal year. WEBS are shares of an
investment company that invests substantially all of its assets in securities
included in the MSCI indices for specific countries. Because the expense
associated with an investment in WEBS can be substantially lower than the
expense of small investments directly in the securities comprising the indices
they seek to track, the Investment Adviser believes that investments in WEBS
of countries that are included in the EAFE Index can provide a cost-effective
means of diversifying the Portfolio's assets across a broad range of equity
securities. See the Additional Statement for further information about WEBS.
    
       
       
The Portfolio may invest in convertible securities and may enter into forward
currency contracts and utilize options, futures contracts and related options
and currency swaps. The Portfolio may also purchase warrants and rights which
entitle the holder to buy equity securities at a specific price for a specific
period of time. In addition, the Portfolio may also invest in certain short-
term fixed income securities as cash reserves. However, it is not anticipated
that the Portfolio will invest in cash reserves, options or futures contracts
and related options as part of a temporary defensive strategy such as lowering
its investment in equity securities to protect against potential market
declines. See "Description of Securities and Common Investment Techniques" and
"Special Risks and Other Considerations" for more information.

purchase of shares equal to 1.00% of the dollar amount invested. See

INTERNATIONAL GROWTH PORTFOLIO
 
The investment objective of the International Growth Portfolio is to seek to
provide long-term capital appreciation. Any income received is incidental to
the objective of capital appreciation. The Portfolio invests principally in
common and preferred stocks and securities convertible into common stock of
foreign issuers. The Portfolio will, under normal market conditions, invest
directly or indirectly at least 65% of its total assets in equity securities
of foreign issuers. The Portfolio selects investments based on such factors as
growth of sales, return on equity, growth and consistency of earnings,
financial condition, market share, product leadership and other investment
criteria. The Portfolio will normally limit its equity investments to the
securities of companies which together with their predecessors have been in
continuous operation for at least five years and have stock market
capitalizations in excess of $200 million. The Portfolio invests in securities
listed on foreign and domestic securities exchanges and securities traded in
foreign and domestic over-the-counter markets, and may invest in unlisted
securities. Securities issued in certain countries are currently accessible to
the Portfolio only through investment in other investment companies that are
specifically authorized to invest in such securities.
 
The Portfolio will be invested at all times in the securities of issuers
located in at least three different foreign countries. These countries may
include, but are not limited to: Argentina, Australia, Austria, Belgium,
Brazil, Canada, Chile, Colombia, Czech Republic, Denmark, Finland, France,
Germany, Greece, Hong Kong, Hungary, Indonesia, Ireland, Israel, Italy, Japan,
Luxembourg, Malaysia, Mexico, the Netherlands, New Zealand, Norway, Peru, the
Philippines, Poland, Portugal, Singapore, South Africa, South Korea, Spain,
Sweden, Switzerland, Taiwan, Thailand, Turkey, the United Kingdom and
Venezuela. Criteria for determining the appropriate distribution of
investments among various countries and regions include prospects for relative
economic growth, expected levels of inflation, government policies influencing
business conditions, the outlook for currency relationships, and the range of
investment opportunities available to international investors.
 
The Portfolio may also enter into forward currency contracts, purchase
convertible bonds, and utilize options, futures contracts and currency swaps.
In addition, the Portfolio may purchase warrants and rights which entitle the
holder to buy equity securities at a specific price for a specific period of
time. Pending investment, as a temporary defensive measure and to meet
anticipated redemption requests, the Portfolio may invest, in accordance with
its investment policies, in various short-term obligations, such as U.S.
Government obligations, high quality money market instruments and repurchase
agreements. See "Description of Securities and Common Investment Techniques"
and "Special Risks and Other Considerations" below for more information.
 
SPECIAL RISKS AND OTHER CONSIDERATIONS
   
FOREIGN SECURITIES. The Short-Intermediate Bond, Bond, Intermediate Bond,
Balanced, Diversified Growth and Focused Growth Portfolios may invest up to
25% of their total assets, and the Global Asset, International Bond,
International Equity Index and International Growth Portfolios will invest a
substantial portion of their total assets as described above, directly or
indirectly in the securities of foreign issuers, whether or not U.S. dollar-
denominated. In addition, each such Portfolio may acquire the obligations of
foreign banks and foreign branches of U.S. banks as stated below under
"Description of Securities and Common Investment Techniques--Short-Term
Obligations." There are certain risks and costs involved in investing in
securities of companies and     
 
                                      42
<PAGE>
 
governments of foreign nations, which are in addition to the usual risks
inherent in U.S. investments. Foreign securities, and in particular foreign
debt securities, are sensitive to changes in interest rates and the interest
rate environment. In addition, investment in foreign debt, or the securities
of foreign governments, will subject a Portfolio to risks, including the risk
that foreign governments may default on their obligations, may not respect the
integrity of such debt, may attempt to renegotiate the debt at a lower rate,
and may not honor investments by United States entities or citizens. The
performance of investments in securities denominated in a foreign currency
will also depend, in part, on the strength of the foreign currency against the
U.S. dollar and the interest rate environment in the country issuing the
currency. Absent other events which could otherwise affect the value of a
foreign security (such as a change in the political climate or an issuer's
credit quality), appreciation in the value of the foreign currency generally
can be expected to increase the value of a foreign currency-denominated
security in terms of U.S. dollars. A rise in foreign interest rates or decline
in the value of the foreign currency relative to the U.S. dollar generally can
be expected to depress the value of a foreign currency-denominated security.
 
Investment in foreign securities also involves higher costs than investment in
U.S. securities, including higher transaction and custody costs as well as the
imposition of additional taxes by foreign governments. Foreign investments may
also involve risks associated with the level of currency exchange rates, less
complete financial information about the issuers, less market liquidity, more
market volatility and political instability. Future political and economic
developments, the possible imposition of withholding taxes on dividend income,
the possible seizure or nationalization of foreign holdings, the possible
establishment of exchange controls or freezes on the convertibility of
currency, or the adoption of other governmental restrictions might adversely
affect an investment in foreign securities. Additionally, foreign banks and
foreign branches of domestic banks may be subject to less stringent reserve
requirements, and to different accounting, auditing and recordkeeping
requirements.
   
In addition, there are other risks of investing in countries with emerging
economies or securities markets. These countries are located in the
Asia/Pacific region, Eastern Europe, Latin and South America and Africa.
Political and economic structures in many 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. Some of these countries may have in the past failed to recognize
private property rights and may have at times nationalized or expropriated the
assets of private companies. In general, the securities markets of these
countries are less liquid, are subject to greater price volatility, have
smaller market capitalizations and have problems with securities registration
and custody. As a result, the risks presented by investments in these
countries are heightened.     
 
While the Portfolios' investments may, if permitted, be denominated in foreign
currencies, the portfolio securities and other assets held by the Portfolios
are valued in U.S. dollars. Currency exchange rates may fluctuate
significantly over short periods of time causing, together with other factors,
a Portfolio's net asset value to fluctuate as well. Currency exchange rates
can be affected unpredictably by the intervention or the failure to intervene
by U.S. or foreign governments or central banks, or by currency controls or
political developments in the U.S. or abroad. A Portfolio's net long and short
foreign currency exposure will not exceed its total asset value. To the extent
that a Portfolio is invested in foreign securities while also maintaining
currency positions, it may be exposed to greater combined risk. The
Portfolios' respective net currency positions may expose them to risks
independent of their securities positions.
 
                                      43
<PAGE>
 
   
Because the securities markets in the following countries are highly
developed, liquid and subject to extensive regulation, the International
Growth Portfolio and International Bond Portfolio may invest more than 25% of
their total assets in the securities of issuers located in Japan, the United
Kingdom, France, Germany or Switzerland. Because the International Equity
Index Portfolio invests in countries according to their weightings in the EAFE
Index, more than 25% of such Portfolio's assets may also be invested in the
securities of issuers in a single country. Investment in a particular country
of 25% or more of the Portfolio's total assets will make the Portfolio's
performance more dependent upon the political and economic circumstances of a
particular country than a mutual fund that is more widely diversified among
issuers in different countries. Although the five foreign countries listed
above have developed economies, they are not immune from these risks. For
example, the expected introduction of a single currency, the euro, on January
1, 1999 for participating nations in the European Economic and Monetary Union
presents unique risks and uncertainties, including: whether the payment and
operational systems of banks and other financial institutions will be ready by
the scheduled launch date; the treatment of outstanding financial contracts
after January 1, 1999 that refer to existing currencies rather than the euro;
the establishment of exchange rates for existing currencies and the euro; and
the creation of suitable clearing and settlement payment systems for the new
currency. These or other factors, including political risks, could cause
market disruptions before or after the introduction of the euro, and could
adversely affect the value of securities held by the Portfolios. Moreover, the
end of the Cold War, the reunification of Germany, the accession of new
Western European members to the European Union and the aspirations of Eastern
European states to join and other political and social events in Europe have
caused considerable economic, social and political dislocation. In addition,
events in the Japanese economy, as well as political and social developments
there have affected Japanese securities and currency markets, and the
relationship of the Japanese yen with other currencies and with the U.S.
dollar. Future political, economic and social developments in Japan and in the
Asia/Pacific regional context can be expected to produce continuing effects on
securities and currency markets.     
 
DERIVATIVE INSTRUMENTS. Each Portfolio may also purchase certain "derivative"
instruments. "Derivative" instruments are instruments that derive value from
the performance of underlying assets, interest or currency exchange rates, or
indices, and include interest rate and currency swaps, futures contracts,
options, forward currency contracts and structured debt obligations (including
collateralized mortgage obligations and other types of asset-backed
securities, "stripped" securities and various floating rate instruments,
including "inverse floaters"). Derivative instruments present, to varying
degrees, market risk that the performance of the underlying assets, exchange
rates or indices will decline; credit risk that the dealer or other
counterparty to the transaction will fail to pay its obligations; volatility
and leveraging risk that, if interest or exchange rates change adversely, the
value of the derivative instrument will decline more than the assets, rates or
indices on which it is based; liquidity risk that a Portfolio will be unable
to sell a derivative instrument when it wants because of lack of market depth
or market disruption; pricing risk that the value of a derivative instrument
(such as an option) will not correlate exactly to the value of the underlying
assets, rates or indices on which it is based; and operations risk that loss
will occur as a result of inadequate systems and controls, human error or
otherwise. Some derivative instruments are more complex than others, and for
those instruments that have been developed recently, data is lacking regarding
their actual performance over complete market cycles. The Investment Advisers
will evaluate the risks presented by the derivative instruments purchased by
the Portfolios, and will determine, in connection with their day-to-day
management of the Portfolios, how they will be used in furtherance of the
Portfolios' investment objectives. It is possible, however, that the
Investment Advisers' evaluations will prove to be inaccurate or incomplete
and, even when accurate and complete, it is possible that the Portfolios will,
because of the risks discussed above, incur loss as a result of their
investments in derivative instruments.
 
 
                                      44

AVERAGE MATURITIES. The Fixed Income Portfolios will normally maintain the
dollar-weighted average maturities of their portfolios within the specified
ranges previously described. The maturities of certain instruments, however,
such as variable and floating rate instruments as well as instruments subject
to prepayment or redemption by the issuers, are subject to estimation. There
can be no assurance that the estimates used by the Fixed Income Portfolios for
such instruments will, in fact, be accurate or that, if inaccurate, a Fixed
Income Portfolio's dollar-weighted average maturity will remain within the
specified limits.     
   
TRACKING VARIANCE. The Investment Adviser believes that under normal market
conditions, the quarterly performance of the Equity Index, Small Company Index,
International Equity Index and U.S. Treasury Index Portfolios, before Portfolio
expenses, will be within a .95 correlation with the S&P Index, Russell Index,
EAFE Index and Lehman Index, respectively. However, there is no assurance that
a Portfolio will be able to do so on a consistent basis. Deviations from the
performance of its designated Index ("tracking variance") may result from
purchases and redemptions of shares of a Portfolio that occur daily, as well as
from the expenses borne by a Portfolio. Such purchases and redemptions may
necessitate the purchase and sale of securities by the Portfolio and the
resulting transaction costs which may be substantial because of the number and
the characteristics of the securities held. In addition, transaction costs are
incurred because sales of securities received in connection with spin-offs and
other corporate reorganizations are made to conform the Portfolio's holdings
with its investment objective. Tracking variance may also occur due to factors
such as the size of a Portfolio, the maintenance of a cash reserve pending
investment or to meet expected redemptions, changes made in the Portfolio's
designated Index or the manner in which the Index is calculated or because the
indexing and investment approach of the Investment Adviser does not produce the
intended goal of the Portfolio. In the event the performance of a Portfolio is
not comparable to the performance of its designated Index, the Board of
Trustees will evaluate the reasons for the deviation and the availability of
corrective measures. If substantial deviation in a Portfolio's performance were
to continue for extended periods, it is expected that the Board of Trustees
would consider recommending to shareholders possible changes to the Portfolio's
investment objective.     
 
SPECIAL RISKS AND OTHER CONSIDERATIONS RELATING TO THE GLOBAL ASSET PORTFOLIO.
Because the Global Asset Portfolio may invest up to 100% of its assets in
shares of other investment companies, the expenses associated with investing in
the Portfolio may be higher than those associated with a portfolio that invests
primarily in the securities of issuers that are not themselves investment
companies. An investor in the Global Asset Portfolio will incur not only a
proportionate share of the expenses of the Portfolio, but also a proportionate
share of expenses of the other Benchmark Portfolios and unaffiliated investment
companies in which the Portfolio invests (collectively, the "underlying
funds"). Investors in the Global Asset Portfolio should realize that they can
invest directly in the underlying funds. However, investors who purchase shares
of these underlying funds directly would not benefit from the asset allocation
services provided by Northern in managing the Global Asset Portfolio, nor from
the Portfolio's direct investments in individual securities. While the Global
Asset Portfolio offers a greater level of diversification than many other types
of mutual funds, the Portfolio should not be considered a complete investment
program for an investor.
   
The Global Asset Portfolio will seek to avoid duplicative fees and the layering
of expenses to a meaningful extent. The Portfolio will only invest in the class
of shares of each Benchmark Portfolio which is currently offered with no sales
or redemption charges, distribution fees or shareholder servicing fees. The
advisory fees payable to Northern under the Portfolio's advisory contract are
for services that are in addition to, rather than duplicative of, services
provided under the advisory contract for any other Benchmark Portfolio or
unaffiliated     
 
                                       45
<PAGE>
 
   
investment company in which the Portfolio invests, including but not limited to
asset allocation and portfolio selection. The administration, custody and
transfer agency fees borne by the Portfolio are also for services that are in
addition to, and not duplicative of, services provided to the underlying funds.
Although the Benchmark Portfolios will not impose sales loads or distribution
fees on investments by the Global Asset Portfolio, it is possible that the
Global Asset Portfolio may pay distribution fees in connection with its
investments in unaffiliated investment companies. These would be indirectly
borne by the Portfolio's investors. In addition, the Global Asset Portfolio
will bear the additional transaction fees payable in connection with
investments in the Small Company Index and International Equity Index
Portfolios.     
 
As a fund that may invest a substantial portion of its assets in other
investment companies, the Global Asset Portfolio will be subject to certain
investment risks. The Global Asset Portfolio's performance is directly related
to the performance of the investment companies in which it invests.
Accordingly, the ability of the Portfolio to meet its investment objective is
directly related to the ability of the underlying funds to meet their
objectives, as well as the allocation among those funds by Northern. There can
be no assurance that the investment objective of any underlying fund will be
achieved. To the extent that one or more underlying funds invest more than 25%
of their total assets in one industry, the Portfolio may, through its
investments in such funds, invest more than 25% of its total assets in such
industry. This indirect concentration may subject the Portfolio to more
volatile price movements than would be the case in the absence of such
concentration. In addition, the structure of the Portfolio may give rise to
"wash" transactions which occur when one underlying fund purchases the same
securities that another underlying fund is selling. These transactions would
cause the Global Asset Portfolio to indirectly incur transaction costs with no
corresponding investment benefit. Because the Portfolio will pursue its global
strategy by investing in underlying funds that invest in different types of
securities, Northern believes that the risk associated with wash transactions
is minimal.
   
From time to time, the underlying Benchmark Portfolios may experience
relatively large purchases or redemptions due to asset allocation decisions
made by Northern in managing the Global Asset Portfolio. While it is impossible
to predict the overall impact of these transactions over time, there could be
adverse effects on the Benchmark Portfolios to the extent that they may be
required to sell securities at times when they would not otherwise do so or
receive cash that cannot be invested in an expeditious manner. There may be tax
consequences associated with purchases and sales of securities, and such sales
may also increase transaction costs. Northern is committed to minimizing the
impact of these transactions on the underlying Benchmark Portfolios to the
extent it is consistent with pursuing the Global Asset Portfolio's investment
objective and will monitor the impact of the Global Asset Portfolio's asset
allocation decisions on the underlying Benchmark Portfolios. Northern will
nevertheless face conflicts in fulfilling its responsibilities because of the
possible differences between the interests of the Global Asset Portfolio and
the interests of the underlying Benchmark Portfolios. In addition, Northern is
subject to conflicts of interest in allocating Global Asset Portfolio assets
among the various Benchmark Portfolios because the fees payable to it or NTQA
by some Benchmark Portfolios are higher than the fees payable by other
Benchmark Portfolios.     
 
DESCRIPTION OF SECURITIES AND COMMON INVESTMENT TECHNIQUES
 
UNITED STATES GOVERNMENT OBLIGATIONS. Each Portfolio may invest, to the extent
consistent with its investment policies, in a variety of U.S. Treasury
obligations consisting of bills, notes and bonds, which principally differ only
in their interest rates, maturities and time of issuance. Each Portfolio (other
than the U.S. Treasury Index
 
                                       46
<PAGE>
 
Portfolio) may also invest in other securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities consisting of bills, notes and
bonds, which principally differ only in their interest rates, maturities and
time of issuance. Obligations of certain agencies and instrumentalities, such
as the Government National Mortgage Association ("GNMA"), are supported by the
full faith and credit of the U.S. Treasury; others, such as those of the
Export-Import Bank of the United States, are supported by the right of the
issuer to borrow from the Treasury; others, such as those of the Federal
National Mortgage Association ("FNMA"), are supported by the discretionary
authority of the U.S. Government to purchase the agency's obligations; still
others are supported only by the credit of the instrumentalities. No assurance
can be given that the U.S. Government would provide financial support to its
agencies or instrumentalities if it is not obligated to do so by law. There is
no assurance that these commitments will be undertaken or complied with in the
future.
 
Securities guaranteed as to principal and interest by the U.S. Government, its
agencies 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 or an agency or instrumentality thereof,
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 will therefore be regarded as
illiquid.
 
CONVERTIBLE SECURITIES. The Short-Intermediate Bond, Bond, Intermediate Bond,
International Bond, Balanced, Global Asset, Diversified Growth, Focused Growth,
International Growth and International Equity Index Portfolios may each acquire
convertible securities. A convertible security is a security that may be
converted either at a stated price or rate within a specified period of time
into a specified number of shares of common stock. By investing in convertible
securities, a Portfolio seeks the opportunity, through the conversion feature,
to participate in the capital appreciation of the common stock into which the
securities are convertible, while earning higher current income than is
available from the common stock. Convertible securities acquired by the
Portfolios will be subject to the same rating requirements as a Portfolio's
investments in its fixed income securities, or if unrated, will be of
comparable quality as determined by the Investment Advisers in accordance with
guidelines approved by the Board of Trustees, except that a Portfolio may
acquire convertible securities rated below investment grade so long as a
Portfolio's investments in all non-investment grade securities does not exceed
the limitations set forth below under "Non-Investment Grade Securities." The
Fixed Income Portfolios will ordinarily sell units of common stock received
upon conversion.
 
CORPORATE OBLIGATIONS. A Portfolio (other than the U.S. Government Securities
and U.S. Treasury Index Portfolios) may purchase debt obligations of domestic
or foreign corporations subject to the Portfolio's minimum rating requirements
for purchases of debt securities. See discussion of "Investment Grade
Securities" and "Non-Investment Grade Securities" below.
   
INVESTMENT GRADE SECURITIES. The Fixed Income, Balanced and Global Asset
Portfolios may invest in fixed income securities of all types, and the Short-
Intermediate Bond, Bond, Intermediate Bond, International Bond, Balanced,
Global Asset, Diversified Growth, Focused Growth, International Growth and
International Equity Index Portfolios may invest a portion of their assets in
convertible securities. Such securities will generally be investment grade.
Investment grade securities include those securities which are rated BBB or
higher by Standard and Poor's Ratings Group ("S&P"), Baa or higher by Moody's
Investors Service, Inc. ("Moody's"), BBB or higher by Duff & Phelps Credit
Rating Co. ("Duff") or BBB or higher by Fitch IBCA Inc. ("Fitch") at the time
of purchase, or if unrated, are of comparable quality as determined by the
Investment Advisers. A security will be considered investment grade if it
receives a rating as described above from either S&P, Moody's, Duff or     
 
                                       47
<PAGE>
 
   
Fitch, even though it has received a lower rating from other rating
organizations. Securities rated BBB by S&P, Duff or Fitch, or Baa by Moody's
have certain speculative characteristics and changes in economic conditions or
other circumstances are more likely to lead to a weakened capacity to make
principal and interest payments than in the case of higher rated securities.
Commercial paper and other short-term obligations acquired by a Portfolio will
be rated A-2 or higher by S&P, P-2 or higher by Moody's, D-2 or higher by Duff,
or F-2 or higher by Fitch at the time of purchase or, if unrated, determined to
be of comparable quality by the Investment Advisers. Subsequent to its purchase
by a Portfolio, a rated security may cease to be rated or its rating may be
reduced below the minimum rating required for purchase by the Portfolio. The
Investment Adviser will consider such an event in determining whether the
Portfolio should continue to hold such security. In addition, certain
Portfolios may acquire fixed income securities rated below investment grade
when the Investment Adviser believes that the investment characteristics of
such securities make them desirable acquisitions. In either case, a Portfolio's
total investment in non-investment grade securities will not exceed the
limitations set forth below under "Non-Investment Grade Securities."     
 
NON-INVESTMENT GRADE SECURITIES. Although the fixed income securities in which
the Fixed Income, Balanced and Global Asset Portfolios may invest and the
convertible securities in which the Short-Intermediate Bond, Bond, Intermediate
Bond, International Bond, Balanced, Global Asset, Diversified Growth, Focused
Growth, International Growth and International Equity Index Portfolios may
invest will normally be rated investment grade at the time of purchase, the
Portfolios (other than the U.S. Government Securities and U.S. Treasury Index
Portfolios) may invest in non-investment grade or convertible securities when
the Investment Advisers believe that the investment characteristics of such
securities make them desirable in light of the Portfolios' investment
objectives and current portfolio mix, so long as under normal market and
economic conditions, (i) no more than 5% of the respective total assets of the
International Bond, International Growth and International Equity Index
Portfolios and no more than 10% of the respective total assets of the Short-
Intermediate Bond, Bond, Intermediate Bond, Balanced, Global Asset, Diversified
Growth and Focused Growth Portfolios are invested in non-investment grade
securities and (ii) such securities are rated "B" or higher at the time of
purchase by at least one major rating agency, or if unrated will be of
comparable quality as determined by the Investment Advisers. Non-investment
grade securities (those that are rated "Ba" or lower by Moody's or "BB" or
lower by S&P, Duff or Fitch) are commonly referred to as "junk bonds." To the
extent that securities, including convertible securities, acquired by a
Portfolio are not rated investment grade, there is a greater risk as to the
timely repayment of the principal on, and timely payment of interest or
dividends with respect to, such securities. Particular risks associated with
lower-rated securities are (a) the relative youth and growth of the market for
such securities, (b) the sensitivity of such securities to interest rate and
economic changes, (c) the lower degree of protection of principal and interest
payments, (d) the relatively low trading market liquidity for the securities,
(e) the impact that legislation may have on the high yield bond market (and, in
turn, on a Portfolio's net asset value and investment practices), and (f) the
creditworthiness of the issuers of such securities. During an economic downturn
or substantial period of rising interest rates, leveraged issuers may
experience financial stress which would adversely affect their ability to
service their principal and interest payment obligations, to meet projected
business goals, and to obtain additional financing. An economic downturn could
also disrupt the market for lower-rated securities and adversely affect the
value of outstanding securities and the ability of the issuers to repay
principal and interest. If the issuer of a security held by a Portfolio
defaulted, the Portfolio could incur additional expenses to seek recovery.
 
FORWARD CURRENCY EXCHANGE CONTRACTS. The Short-Intermediate Bond, Bond,
Intermediate Bond, International Bond, Balanced, Global Asset, Diversified
Growth, Focused Growth, International Growth and International
 
                                       48
<PAGE>
 
Equity Index Portfolios may enter into forward currency exchange contracts for
hedging purposes and in an effort to reduce the level of volatility caused by
changes in foreign currency exchange rates or where such transactions are
economically appropriate for the reduction of risks inherent in the ongoing
management of the Portfolios. The Global Asset, International Bond and
International Growth Portfolios may also enter into forward currency exchange
contracts for speculative purposes (to seek to increase total return). In
addition, the Global Asset, International Growth and International Bond
Portfolios may engage in cross-hedging by using forward contracts in one
currency to hedge against fluctuations in the value of securities denominated
in a different currency if Northern believes that there is a pattern of
correlation between the two currencies.
   
A forward currency exchange contract is 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 contract. Although such contracts tend to minimize the risk of loss due to a
decline in the value of the hedged currency, at the same time they tend to
limit any potential gain that might be realized should the value of such
currency increase. Consequently, a Portfolio may choose to refrain from
entering into such contracts. In connection with forward currency exchange
contracts, the Portfolios will segregate liquid assets in accordance with
applicable requirements of the SEC or will otherwise cover their positions.
       
The International Bond Portfolio may also invest in debt securities denominated
in the European Currency Unit ("ECU"), which is a "basket" consisting of
specified amounts in the currencies of certain of the twelve member states of
the European Community. The specific amounts of currencies comprising the ECU
may be adjusted by the Council of Ministries of the European Community from
time to time to reflect changes in relative values of the underlying
currencies. In addition, the Portfolio may invest in securities denominated in
other currency "baskets."     
 
OPTIONS. Each Portfolio may write covered call options, buy put options, buy
call options and write secured put options for hedging (or cross-hedging)
purposes or for the purpose of earning additional income. Such options may
relate to particular securities, foreign or domestic securities indices,
financial instruments or foreign currencies and may or may not be listed on a
foreign or domestic securities exchange and issued by the Options Clearing
Corporation. The Portfolios will not purchase put and call options in an amount
that exceeds 5% of their respective net assets at the time of purchase. The
aggregate value of a Portfolio's assets that will be subject to options written
by the Portfolio will not exceed 25% of its net assets at the time the option
is written.
 
In the case of a call option on a security or currency, the option is "covered"
if a Portfolio owns the security or currency underlying the call or has an
absolute and immediate right to acquire that security or currency without
additional cash consideration (or, if additional cash consideration is
required, liquid assets in such amount are held in a segregated account by its
custodian) upon conversion or exchange of other securities or instruments held
by it. For a call option on an index, the option is covered if a Portfolio
maintains with its custodian a portfolio of securities substantially
replicating the movement of the index, or liquid assets equal to the contract
value. A call option is also covered if a Portfolio holds a call on the same
security, currency or index as the call written where the exercise price of the
call held is (i) equal to or less than the exercise price of the call written,
or (ii) greater than the exercise price of the call written provided the
difference is maintained by the Portfolio in liquid assets in a segregated
account with its custodian. Put options written by a Portfolio are "secured" if
the Portfolio maintains liquid assets in a segregated account with its
custodian in an amount not less than the exercise price of the option at all
times during the option period.
 
 
                                       49
<PAGE>
 
Options trading is a highly specialized activity which entails greater than
ordinary investment risks. A call option for a particular security or currency
gives the purchaser of the option the right to buy, and a writer the obligation
to sell, the underlying security or currency at the stated exercise price at
any time prior to the expiration of the option, regardless of the market price
of the security or currency. The premium paid to the writer is in consideration
for undertaking the obligation under the option contract. A put option for a
particular security or currency gives the purchaser the right to sell the
security or currency at the stated exercise price to the expiration date of the
option, regardless of the market price of the security or currency. In contrast
to an option on a particular security, an option on an index provides the
holder with the right to make or receive a cash settlement upon exercise of the
option. The amount of this settlement will be equal to the difference between
the closing price of the index at the time of exercise and the exercise price
of the option expressed in dollars, times a specified multiple.
 
Each Portfolio will invest and trade in unlisted over-the-counter options only
with firms deemed creditworthy by the Investment Advisers. However, unlisted
options are not subject to the protections afforded purchasers of listed
options by the Options Clearing Corporation, which performs the obligations of
its members which fail to perform them in connection with the purchase or sale
of options.
   
FUTURES CONTRACTS AND RELATED OPTIONS. Each Portfolio may invest in futures
contracts and options on futures contracts for hedging purposes, to increase
total return (i.e., for speculative purposes) or to maintain liquidity to meet
potential shareholder redemptions, invest cash balances or dividends or
minimize trading costs. The value of a Portfolio's contracts may equal up to
100% of its total assets, although a Portfolio will not purchase or sell a
futures contract unless immediately after any such transaction the sum of the
aggregate amount of margin deposits on its existing futures positions and the
amount of premiums paid for related options entered into for other than bona
fide hedging purposes is 5% or less of its total assets.     
 
Futures contracts obligate a Portfolio, at maturity, to take or make delivery
of certain domestic or foreign securities, the cash value of a securities index
or, in the case of the International Bond, International Growth, International
Equity Index and Global Asset Portfolios, a stated quantity of a foreign
currency. When used as a hedge, a Portfolio may sell a futures contract in
order to offset a decrease in the market value of its portfolio securities that
might otherwise result from a market decline or currency exchange fluctuations.
A Portfolio may do so either to hedge the value of its portfolio of securities
as a whole, or to protect against declines, occurring prior to sales of
securities, in the value of the securities to be sold. Conversely, a Portfolio
may purchase a futures contract as a hedge in anticipation of purchases of
securities. In addition, a Portfolio may utilize futures contracts in
anticipation of changes in the composition of its portfolio holdings.
   
The Portfolios may purchase and sell call and put options on futures contracts
traded on a domestic or foreign exchange or board of trade. When a Portfolio
purchases an option on a futures contract, it has the right to assume a
position as a purchaser or seller of a futures contract at a specified exercise
price during the option period. When a Portfolio sells an option on a futures
contract, it becomes obligated to purchase or sell a futures contract if the
option is exercised. In connection with a Portfolio's position in a futures
contract or option thereon, the Portfolio will segregate liquid assets in
accordance with applicable requirements of the SEC or otherwise cover its
position.     
   
The primary risks associated with the use of futures contracts and options are:
(i) imperfect correlation between the change in market value of the securities
held by a Portfolio and the price of futures contracts and options; (ii) the
possible inability to close a futures contract when desired; (iii) losses due
to unanticipated market movements which are potentially unlimited; and (iv) the
Investment Adviser's ability to predict correctly the     
 
                                       50

direction of securities prices, interest rates, currency exchange rates and
other economic factors. For a further discussion see "Additional Investment
Information--Futures Contracts and Related Options" and Appendix B in the
Additional Statement.
 
The Portfolios intend to comply with the regulations of the Commodity Futures
Trading Commission exempting the Portfolios from registration as a "commodity
pool operator."
   
INTEREST RATE SWAPS, FLOORS AND CAPS AND CURRENCY SWAPS. Each Fixed Income
Portfolio (other than the U.S. Treasury Index Portfolio) and each of the Global
Asset and Balanced Portfolios may, in order to protect its value from interest
rate fluctuations and to hedge against fluctuations in the floating rate
market, enter into interest rate swaps or purchase interest rate floors or
caps. The Portfolios expect to enter into these hedging transactions primarily
to preserve a return or spread of a particular investment or portion of its
holdings and to protect against an increase in the price of securities the
Portfolios anticipate purchasing at a later date. Interest rate swaps involve
the exchange by a Portfolio with another party of their respective commitments
to pay or receive interest (e.g., an exchange of floating rate payments for
fixed rate payments). 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 such interest rate floor. The purchase of an interest
rate cap entitles the purchaser, to the extent that a specified index exceeds a
predetermined interest rate, to receive payments of interest on a notional
principal amount from the party selling such interest rate cap. In order to
protect against currency fluctuations, the International Bond, International
Growth, International Equity Index and Global Asset Portfolios may enter into
currency swaps. Currency swaps involve the exchange of the rights of a
Portfolio and another party to make or receive payments in specified
currencies.     
   
The net amount of the excess, if any, of a Portfolio's obligations over its
entitlements with respect to each interest rate or currency swap will be
accrued on a daily basis and the Portfolio will segregate an amount of liquid
assets having an aggregate net asset value at least equal to such accrued
excess. If the other party to an interest rate swap defaults, a Portfolio's
risk of loss consists of the net amount of interest payments that the Portfolio
is contractually entitled to receive. In contrast, currency swaps usually
involve the delivery of the entire principal value 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. A Portfolio will not
enter into any interest rate swap, floor or cap transaction or any currency
swap unless the unsecured commercial paper, senior debt, or claims paying
ability of the other party is rated either A or A-1 or better by S&P, Duff or
Fitch, or A or P-1 or better by Moody's.     
 
SECURITIES LENDING. The Portfolios may seek additional income from time to time
by lending their respective portfolio securities on a short-term basis to
banks, brokers and dealers under agreements requiring that the loans be secured
by collateral in the form of cash, cash equivalents, U.S. Government securities
or irrevocable bank letters of credit maintained on a current basis equal in
value to at least the market value of the securities loaned. A Portfolio may
not make such loans in excess of 33 1/3% of the value of the Portfolio's total
assets (including the loan collateral). Loans of securities involve risks of
delay in receiving additional collateral or in recovering the securities
loaned, or possible loss of rights in the collateral should the borrower of the
securities become insolvent. The proceeds received by a Portfolio in connection
with loans of portfolio securities may be invested in U.S. Government
securities and other liquid high grade debt obligations.
 
FORWARD COMMITMENTS, WHEN-ISSUED SECURITIES AND DELAYED-DELIVERY TRANSACTIONS.
The Portfolios may purchase or sell securities on a when-issued or delayed-
delivery basis and make contracts to purchase or sell
 
                                       51
<PAGE>
 
   
securities for a fixed price at a future date beyond customary settlement time.
Securities purchased on a when-issued, delayed-delivery or forward commitment
basis involve a risk of loss if the value of the security to be purchased
declines prior to the settlement date. Conversely, securities sold on a
delayed-delivery or forward commitment basis involve the risk that the value of
the security to be sold may increase prior to the settlement date. Securities
purchased on a forward commitment basis also involve the risk that the seller
may fail to deliver the security on the agreed upon future date. A Portfolio is
required to segregate liquid assets until three days prior to the settlement
date having a value (determined daily) at least equal to the amount of the
Portfolio's purchase commitments, or to otherwise cover its position. Although
the Portfolios would generally purchase securities on a when-issued, delayed-
delivery or a forward commitment basis with the intention of acquiring the
securities, the Portfolios may dispose of such securities prior to settlement
if the Investment Advisers deem it appropriate to do so.     
   
BORROWINGS. The Portfolios are authorized to make limited borrowings for
temporary purposes to the extent described below under "Investment
Restrictions." If the securities held by the Portfolios should decline in value
while borrowings are outstanding, the net asset value of the Portfolios'
outstanding shares will decline in value by proportionately more than the
decline in value suffered by the Portfolios' securities. Borrowings may be
effected through reverse repurchase agreements under which the Portfolios would
sell portfolio securities to financial institutions such as banks and broker-
dealers and agree to repurchase them at a particular date and price. The Fixed
Income, Balanced and Global Asset Portfolios may utilize reverse repurchase
agreements when it is anticipated that the interest income to be earned from
the investment of the proceeds of the transaction is greater than the interest
expense of the reverse repurchase transaction. See "Description of Securities
and Common Investment Techniques--Reverse Repurchase Agreements" below for
additional information concerning reverse repurchase agreements. For additional
information on borrowings, see "Additional Investment Information--Investment
Restrictions" in the Additional Statement.     
 
SHORT-TERM OBLIGATIONS. Subject to each Portfolio's investment objective and
policies, a Portfolio may also invest in short-term U.S. government
obligations, high quality money market instruments and repurchase agreements,
pending investment, to meet anticipated redemption requests, or as a temporary
defensive measure. Such obligations may include those issued by foreign banks
and foreign branches of U.S. banks. See "Special Risks and Other
Considerations--Foreign Securities" above.
 
REPURCHASE AGREEMENTS. The Portfolios may agree to purchase portfolio
securities from financial institutions such as banks and broker/dealers which
are deemed to be creditworthy by the Investment Advisers under guidelines
approved by the Board of Trustees subject to the seller's agreement to
repurchase them at a mutually agreed upon date and price ("repurchase
agreements"). Although the securities subject to a repurchase agreement may
bear maturities exceeding one year, settlement for the repurchase agreement
will never be more than one year after a Portfolio's acquisition of the
securities and normally will be within a shorter period of time. Securities
subject to repurchase agreements are held either by the Trust's custodian or
subcustodian (if any), or in the Federal Reserve/Treasury Book-Entry System.
The seller under a repurchase agreement will be required to maintain the value
of the securities which are subject to the agreement and held by a Portfolio in
an amount that exceeds the agreed upon repurchase price (including accrued
interest). Default by or bankruptcy of the seller would, however, expose a
Portfolio to possible loss because of adverse market action or delays in
connection with the disposition of the underlying obligations.
 
 
                                       52
<PAGE>
 
   
REVERSE REPURCHASE AGREEMENTS. The Portfolios may enter into reverse repurchase
agreements which involve the sale of securities held by them, with an agreement
to repurchase the securities at an agreed upon price (including interest) and
date. The Portfolios will use the proceeds of reverse repurchase agreements to
purchase other securities either maturing, or under an agreement to resell, at
a date simultaneous with or prior to the expiration of the reverse repurchase
agreement. The Portfolios will utilize reverse repurchase agreements, which may
be viewed as borrowings (or leverage), when it is anticipated that the interest
income to be earned from the investment of the proceeds of the transaction is
greater than the interest expense of the reverse repurchase transaction.
Reverse repurchase agreements involve the risks that the interest income earned
from the investment of the proceeds of the transaction will be less than the
interest expense of the reverse repurchase agreement, that the market value of
the securities sold by the Portfolio may decline below the price of the
securities the Portfolio is obligated to repurchase and that the securities may
not be returned to the Portfolio. During the time a reverse repurchase
agreement is outstanding, a Portfolio will segregate liquid assets having a
value at least equal to the repurchase price. A Portfolio may enter into
reverse repurchase agreements with banks, brokers and dealers, and has the
authority to enter into reverse repurchase agreements in amounts not exceeding
in the aggregate one-third of the Portfolio's total assets. See "Additional
Investment Information--Investment Restrictions" in the Additional Statement.
       
VARIABLE AND FLOATING RATE INSTRUMENTS. The Portfolios may purchase rated and
unrated variable and floating rate instruments. These instruments may include
variable amount master demand notes that permit the indebtedness thereunder to
vary in addition to providing for periodic adjustments in the interest rate.
The Portfolios may also invest in leveraged inverse floating rate debt
instruments ("inverse floaters"). The interest rate on an inverse floater
resets in the opposite direction from the market rate of interest to which the
inverse floater is indexed. An inverse floater may be considered to be
leveraged to the extent that its interest rate varies by a magnitude that
exceeds the magnitude of the change in the index rate of interest. The higher
degree of leverage inherent in inverse floaters is associated with greater
volatility in their market values. Accordingly, the duration of an inverse
floater may exceed its stated final maturity. The Portfolios may deem the
maturity of variable and floating rate instruments to be less than their stated
maturities based on their variable and floating rate features and/or their put
features subject to applicable SEC regulations. Unrated variable and floating
rate instruments will be determined by the Investment Advisers to be of
comparable quality at the time of the purchase to rated instruments which may
be purchased by the Portfolios.     
 
The absence of an active secondary market with respect to particular variable
and floating rate instruments could make it difficult for the Portfolios to
dispose of the instruments if the issuer defaulted on its payment obligation or
during periods that the Portfolios are not entitled to exercise their demand
rights, and the Portfolios could, for these or other reasons, suffer a loss
with respect to such instruments. Variable and floating rate instruments
including inverse floaters held by a Portfolio will be subject to the
Portfolio's 15% limitation on illiquid investments when the Portfolio may not
demand payment of the principal amount within seven days absent a reliable
trading market.
 
INVESTMENT COMPANIES. In connection with the management of their daily cash
positions, the Portfolios may invest in securities issued by other investment
companies which invest in short-term, high-quality debt securities and which
determine their net asset value per share based on the amortized cost or penny-
rounding method of valuation. The U.S. Treasury Index, Equity Index, Small
Company Index and International Equity Index Portfolios may also invest in
shares of other investment companies that are structured to seek a similar
correlation to the performance of the Lehman Index, S&P Index, Russell Index or
EAFE Index, respectively. The International Bond, International Growth,
International Equity Index and Global Asset Portfolios may also
 
                                       53
<PAGE>
 
   
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. As
stated above, the International Equity Index and Global Asset Portfolios may
invest in WEBS and similar securities of investment companies that invest in
securities included in foreign securities indices. In addition, the Portfolios
may invest in securities issued by other investment companies if otherwise
consistent with their respective investment objectives and policies. As a
shareholder of another investment company, a Portfolio would bear, along with
other shareholders, its pro rata portion of the other investment company's
expenses including advisory fees. These expenses would be in addition to the
advisory fees and other expenses the Portfolio bears directly in connection
with its own operations.     
          
Investments by a Portfolio in other investment companies will be subject to the
limitations of the 1940 Act or, in the case of the Global Asset Portfolio, any
exemptive order that may be granted by the SEC to the Trust. These limitations
are discussed in the Additional Statement. Although the Portfolios do not
expect to do so in the foreseeable future, a Portfolio is authorized to invest
substantially all of its assets in a single open-end investment company or
series thereof with substantially the same investment objective, policies and
fundamental restrictions as the Portfolio.     
          
MONEY MARKET BENCHMARK PORTFOLIOS. The Global Asset Portfolio may also invest
in shares of the money market investment portfolios offered by the Trust and
advised by Northern. Each of the Government Select, Government and Diversified
Assets Portfolios seek to maximize current income to the extent consistent with
the preservation of capital and maintenance of liquidity. The Tax-Exempt
Portfolio seeks to provide, to the extent consistent with the preservation of
capital and prescribed portfolio standards, a high level of income exempt from
regular Federal income tax. The Government Select Portfolio invests in selected
short-term obligations of the U.S. Government, its agencies and
instrumentalities the interest on which is generally exempt from state income
taxation. The Government Portfolio invests in short-term obligations of the
U.S. Government, its agencies and instrumentalities and related repurchase
agreements. The Diversified Assets Portfolio invests in money market
instruments of both U.S. and foreign issuers, including certificates of
deposit, bankers' acceptances, commercial paper and repurchase agreements. The
Tax-Exempt Portfolio invests primarily in short-term municipal instruments the
interest on which is exempt from regular Federal income tax.     
   
The money market Benchmark Portfolios attempt to maintain a stable net asset
value of $1.00 per share and value their assets using the amortized cost method
in accordance with SEC regulations. There is no assurance, however, that the
money market Benchmark Portfolios will be successful in maintaining their per
share value at $1.00 on a continuous basis.     
   
ILLIQUID OR RESTRICTED SECURITIES. Each Portfolio may invest up to 15% of its
net assets in securities which are illiquid. Illiquid securities would
generally include repurchase agreements and time deposits with
notice/termination dates in excess of seven days, certain unlisted over-the-
counter options, certain guaranteed investment contracts ("GICs") and other
securities that are traded in the United States but are subject to trading
restrictions because they are not registered under the Securities Act of 1933
(the "1933 Act").     
 
If otherwise consistent with their respective investment objectives and
policies, the Portfolios may purchase domestically-traded securities which are
not registered under the 1933 Act but which can be sold to "qualified
institutional buyers" in accordance with Rule 144A under the 1933 Act. Any such
security will not be considered illiquid so long as it is determined by the
Investment Advisers, under guidelines approved by the Trust's Board
 
                                       54
<PAGE>
 
of Trustees, that an adequate trading market exists for that security. This
investment practice could have the effect of increasing the level of
illiquidity in a Portfolio during any period that qualified institutional
buyers become uninterested in purchasing these restricted securities.
   
STRIPPED OBLIGATIONS. To the extent consistent with their investment
objectives, the Fixed Income, Balanced and Global Asset Portfolios may
purchase Treasury receipts and other "stripped" securities that evidence
ownership in either the future interest payments or the future principal
payments on U.S. Government and other domestic and foreign obligations. These
participations, which may be issued by the U.S. Government (or a U.S.
Government agency or instrumentality), foreign governments or by private
issuers such as banks and other financial institutions, are issued at a
discount to their "face value," and may include stripped mortgage-backed
securities ("SMBS"), which are derivative multi-class mortgage securities.
Stripped securities, particularly SMBS, may exhibit greater price volatility
than ordinary debt securities because of the manner in which their principal
and interest are returned to investors.     
 
CUSTODIAL RECEIPTS FOR TREASURY SECURITIES. Each Fixed Income Portfolio (other
than the U.S. Treasury Index and International Bond Portfolios), the Balanced
Portfolio and the Global Asset Portfolio may also purchase participations in
trusts that hold U.S. Treasury securities (such as TIGRs and CATS) where the
trust participations evidence ownership in either the future interest payments
or the future principal payments on the U.S. Treasury obligations. Like other
stripped securities, these participations are also normally issued at a
discount to their "face value," and may exhibit greater price volatility than
ordinary debt securities because of the manner in which their principal and
interest are returned to investors. Investments by a Portfolio in such
receipts will not exceed 5% of the value of the Portfolio's total assets.
 
BANK OBLIGATIONS. The Portfolios may invest in domestic and foreign bank
obligations, including certificates of deposit, bank and deposit notes,
bankers' acceptances and fixed time deposits. Such obligations may be general
obligations of the parent bank or may be limited to the issuing branch or
subsidiary by the terms of the specific obligation or by government
regulation.
 
ASSET-BACKED SECURITIES. The U.S. Government Securities Portfolio may purchase
securities that are secured or backed by mortgages and issued by an agency of
the U.S. Government. The Short-Intermediate Bond, Bond, Intermediate Bond,
International Bond, Balanced and Global Asset Portfolios may purchase asset-
backed securities that are secured or backed by mortgages or other assets
(e.g., automobile loans, credit card receivables and other financial assets)
and are issued by entities such as GNMA, FNMA, FHLMC, commercial banks,
financial companies, finance subsidiaries of industrial companies, savings and
loan associations, mortgage banks, investment banks and certain special
purpose entities. Asset-backed securities acquired by such Portfolios will be
rated BBB or better by S&P, Duff or Fitch, or Baa or better by Moody's at the
time of purchase or, if not rated, will be determined by Northern to be of
comparable quality. The Portfolios will not purchase non-mortgage asset-backed
securities that are not rated by S&P, Duff, Fitch or Moody's.
 
Presently there are several types of mortgage-backed securities that may be
acquired by the Short-Intermediate Bond, Bond, Intermediate Bond,
International Bond, Balanced and Global Asset Portfolios, including guaranteed
mortgage pass-through certificates, which provide the holder with a pro rata
interest in the underlying mortgages, and collateralized mortgage obligations
("CMOs"), which provide the holder with a specified interest in the cash flow
of a pool of underlying mortgages or other mortgage-backed securities. Issuers
of CMOs ordinarily elect to be taxed as pass-through entities known as real
estate mortgage investment conduits ("REMICs"). CMOs are issued in multiple
classes, each with a specified fixed or floating interest rate and a final
distribution date. The
 
                                      55
<PAGE>
 
relative payment rights of the various CMO classes may be structured in a
variety of ways. The Portfolios will not purchase "residual" CMO interests,
which normally exhibit greater price volatility.
 
The yield characteristics of asset-backed securities differ from traditional
debt securities. A major difference is that the principal amount of the
obligations may be prepaid at any time because the underlying assets (i.e.,
loans) generally may be prepaid at any time. As a result, if an asset-backed
security is purchased at a premium, a prepayment rate that is faster than
expected will reduce yield to maturity, while a prepayment rate that is slower
than expected will have the opposite effect of increasing yield to maturity.
Conversely, if an asset-backed security is purchased at a discount, faster
than expected prepayments will increase, while slower than expected
prepayments will decrease, yield to maturity. In calculating the average
weighted maturity of the U.S. Government Securities, Short-Intermediate Bond,
Bond, Intermediate Bond and International Bond Portfolios or the fixed income
portion of the Balanced Portfolio, the maturity of asset-backed securities
will be based on estimates of average life.
 
Prepayments on asset-backed securities generally increase with falling
interest rates and decrease with rising interest rates; furthermore,
prepayment rates are influenced by a variety of economic and social factors.
In general, the collateral supporting non-mortgage asset-backed securities is
of shorter maturity than mortgage loans and is less likely to experience
substantial prepayments. Like other fixed income securities, when interest
rates rise the value of an asset-backed security generally will decline;
however, when interest rates decline, the value of an asset-backed security
with prepayment features may not increase as much as that of other fixed
income securities.
   
The value of asset-backed securities may change because of actual or perceived
changes in the creditworthiness of the originator, servicing agent, or the
financial institution providing credit support. In addition, non-mortgage
asset-backed securities involve certain risks not presented by mortgage-backed
securities. Primarily, these securities do not have the benefit of the same
security interest in the underlying collateral. 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 debtors
the right to set off certain amounts owed on the credit cards, thereby
reducing the balance due. Most issuers of automobile receivables permit the
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
related automobile receivables. 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
an effective security interest in all of the obligations backing such
receivables. Therefore, there is a possibility that recoveries on repossessed
collateral may not, in some cases, be able to support payment on these
securities.     
 
EXCHANGE RATE-RELATED SECURITIES. The Short-Intermediate Bond, Bond,
Intermediate Bond, International Bond, Balanced, and Global Asset Portfolios
may invest in securities for which the principal repayment at maturity, while
paid in U.S. dollars, is determined by reference to the exchange rate between
the U.S. dollar and the currency of one or more foreign countries ("Exchange
Rate-Related Securities"). The interest payable on these securities is
denominated in U.S. dollars and is not subject to foreign currency risk and,
in most cases, is paid at rates higher than most other similarly rated
securities in recognition of the foreign currency risk component of Exchange
Rate-Related Securities. Investments in Exchange Rate-Related Securities
entail certain risks. There is the possibility of significant changes in rates
of exchange between the U.S. dollar and any foreign currency to which an
Exchange Rate-Related Security is linked. In addition, potential illiquidity
in the forward foreign
 
                                      56
<PAGE>
 
exchange market and the high volatility of the foreign exchange market may
from time to time combine to make it difficult to sell an Exchange Rate-
Related Security prior to maturity without incurring a significant price loss.
 
GUARANTEED INVESTMENT CONTRACTS. The Short-Intermediate Bond, Bond,
Intermediate Bond, Balanced and Global Asset Portfolios may make limited
investments in guaranteed investment contracts ("GICs") issued by U.S.
insurance companies. Pursuant to such contracts, a Portfolio makes cash
contributions to a deposit fund of the insurance company's general account.
The insurance company then credits to the Portfolio on a monthly basis
interest which is based on an index (in most cases this index is expected to
be the Salomon Brothers CD Index), but is guaranteed not to be less than a
certain minimum rate. A GIC is normally a general obligation of the issuing
insurance company and not a separate account. The purchase price paid for a
GIC becomes part of the general assets of the insurance company, and the
contract is paid from the company's general assets. A Portfolio will only
purchase GICs from insurance companies which, at the time of purchase, have
assets of $1 billion or more and meet quality and credit standards established
by Northern. Generally, GICs are not assignable or transferable without the
permission of the issuing insurance companies, and an active secondary market
in GICs does not currently exist. Therefore, GICs will be subject to a
Portfolio's limitation on investments in illiquid securities when a Portfolio
may not demand payment of the principal amount within seven days and a
reliable trading market is absent.
 
WARRANTS. The Balanced, Global Asset, Diversified Growth, Focused Growth,
International Growth, Small Company Index and International Equity Index
Portfolios may invest up to 5% of their respective assets at the time of
purchase in warrants and similar rights (other than those that have been
acquired in units or attached to other securities). Warrants represent rights
to purchase securities at a specific price valid for a specific period of
time. The Balanced, Global Asset, Diversified Growth, Focused Growth and
International Growth Portfolios may also purchase bonds that are issued in
tandem with warrants. The prices of warrants do not necessarily correlate with
the prices of the underlying securities.
 
AMERICAN, EUROPEAN AND GLOBAL DEPOSITORY RECEIPTS. The Balanced, Global Asset,
Diversified Growth, Focused Growth, International Growth and International
Equity Index Portfolios may invest in securities of foreign issuers in the
form of American Depository Receipts ("ADRs"), European Depository Receipts
("EDRs") and Global Depository Receipts ("GDRs") or similar securities
representing securities of foreign issuers. These securities may not be
denominated in the same currency as the securities they represent. ADRs are
receipts typically issued by a United States bank or trust company evidencing
ownership of the underlying foreign securities and are denominated in U.S.
dollars. EDRs and GDRs are receipts issued by a non-U.S. financial institution
evidencing ownership of the underlying foreign or U.S. securities and are
generally denominated in foreign currencies. ADRs may be listed on a national
securities exchange or may be traded in the over-the-counter market. EDRs and
GDRs are generally designed for use in a foreign securities exchange and over-
the-counter markets. Investments in ADRs, EDRs and GDRs involve risks similar
to those accompanying direct investments in foreign securities. See "Special
Risks and Other Considerations--Foreign Securities" above.
   
Certain such institutions issuing ADRs, EDRs and GDRs may not be sponsored by
the issuer. A non-sponsored depository may not provide the same shareholder
information that a sponsored depository is required to provide under its
contractual arrangement with the issuer. The Balanced, Diversified Growth and
Focused Growth Portfolios will limit investments in ADRs to 20% of their
respective assets and will limit investments in EDRs and GDRs to 5% of their
respective assets.     
 
                                      57
<PAGE>
 
FIXED INCOME INVESTMENTS. Even though interest-bearing securities are
investments which often offer a stable stream of income, the prices of fixed
income securities will vary inversely with changes in the prevailing level of
interest rates. These securities experience appreciation when interest rates
decline and depreciation when interest rates rise. An investment portfolio
consisting of fixed income securities will react in a similar manner.
Generally, the longer the maturity of a fixed income security, the higher its
yield and the greater its price volatility. Conversely, the shorter the
maturity, the lower the yield but the greater the price stability. The values
of fixed income securities also may be affected by changes in the credit
rating or financial condition of the issuing entities. A security's rating
normally depends on the likelihood that the borrower will meet each interest
and principal installment on a timely basis. As a result, lower-rated bonds
typically yield more than higher-rated bonds of the same maturity. Credit
ratings evaluate the safety of principal and interest payments, not market
risk, and rating agencies may or may not make timely changes in a rating to
reflect economic or company conditions that affect a security's market value.
As a result, the ratings of rating services are used by the Investment
Advisers only as indicators of investment quality. For a more complete
discussion of ratings, see Appendix A to the Additional Statement.
   
In addition, fixed income securities may be subject to both call risk and
extension risk. Call risk (i.e., where the issuer exercises its right to pay
principal on an obligation earlier than scheduled) causes cash flow to be
returned earlier than expected. This typically results when interest rates
have declined, and a Portfolio may be unable to recoup all of its initial
investment and will also suffer from having to reinvest in lower yielding
securities. Extension risk (i.e., where the issuer exercises its right to pay
principal on an obligation later than scheduled) causes cash flows to be
returned later than expected. This typically results when interest rates have
increased and a Portfolio will suffer from the inability to invest in higher
yielding securities.     
   
PORTFOLIO TURNOVER. The portfolio turnover rate of the Global Asset,
International Bond, International Growth and International Equity Index
Portfolios will be affected by changes in country and currency weightings, as
well as changes in the holdings of specific issuers and investments in issuers
in smaller or emerging markets. In addition, the portfolio turnover rate of
the Global Asset Portfolio will be affected by Northern's decisions to
reallocate the Portfolio's assets from time to time among and within the
market segments discussed above in response to economic and market conditions.
The Trust cannot accurately predict the turnover rate for any Portfolio, which
may vary from year to year. The portfolio turnover rate of each Portfolio for
the last fiscal year or fiscal period, as the case may be, except the Global
Asset Portfolio, which had not commenced operations during the periods
reported, is stated above under "Financial Highlights." It is expected that
the portfolio turnover rate for the Global Asset Portfolio will not exceed
200% during the current fiscal year. High portfolio turnover (in excess of
100%) may result in the realization of short-term capital gains which are
taxable to unitholders as ordinary income (see "Taxes"). In addition, high
portfolio turnover rates may result in corresponding increases in brokerage
commissions and other transaction costs. The Portfolios will not consider
portfolio turnover rate a limiting factor in making investment decisions
consistent with their respective objectives and policies.     
   
MISCELLANEOUS. The Equity Index, Small Company Index and International Equity
Index Portfolios may experience higher custody costs than other stock funds
because they maintain large portfolios of securities consistent with their
respective investment objectives.     
 
Each Portfolio may also purchase other types of financial instruments, however
designated, whose investment and credit quality characteristics are determined
by the Investment Advisers to be substantially similar to those of any other
investment otherwise permitted by the investment policies described above.
 
                                      58
<PAGE>
 
   
Pursuant to an SEC order, each Portfolio may engage in principal transactions
effected in the ordinary course of business with Goldman Sachs.     
 
INVESTMENT RESTRICTIONS
   
The Portfolios are subject to certain investment restrictions which, as
described in more detail in the Additional Statement, are fundamental policies
that cannot be changed without the approval of a majority of the outstanding
shares of a Portfolio. These fundamental policies relate, among other things,
to the classification of each Portfolio (except the International Bond
Portfolio) as a diversified investment company under the 1940 Act, and to the
policy of each Portfolio not to invest more than 25% of its total assets in
securities of issuers in any one industry (with certain limited exceptions).
In addition, each Portfolio may borrow money from banks for temporary or
emergency purposes or to meet redemption requests, provided that the Portfolio
maintains asset coverage of at least 300% for all such borrowings.     
   
As a non-fundamental investment restriction that can be changed without
shareholder approval, the International Bond Portfolio may not, at the end of
any tax quarter, invest more than 5% of the total value of its assets in the
securities of any one issuer (except U.S. Government securities), except that
up to 50% of the total value of the Portfolio's assets may be invested in any
securities without regard to this 5% limitation so long as no more than 25% of
the total value of its assets is invested in the securities of any one issuer
(except U.S. Government securities).     
 
                               TRUST INFORMATION
 
BOARD OF TRUSTEES
 
The business and affairs of the Trust and each Portfolio are managed under the

INVESTMENT ADVISERS, TRANSFER AGENT AND CUSTODIAN
   
Northern, which has offices at 50 S. LaSalle Street, Chicago, Illinois 60675,
serves as investment adviser for all Portfolios except the U.S. Treasury
Index, Equity Index, Small Company Index and International Equity Index
Portfolios. Northern Trust Quantitative Advisors, Inc. ("NTQA"), an affiliate
of Northern which also has offices at 50 S. LaSalle Street, Chicago, IL 60675,
acts as investment adviser to the U.S. Treasury Index, Equity Index, Small
Company Index and International Equity Index Portfolios. Northern also serves
as transfer agent and custodian for each Portfolio. As transfer agent,
Northern performs various administrative servicing functions, and any
shareholder inquiries should be directed to it.     
   
Northern, a member of the Federal Reserve System, is an Illinois state-
chartered commercial bank and the principal subsidiary of Northern Trust
Corporation, a bank holding company. Northern was formed in 1889 with
capitalization of $1 million. NTQA is an Illinois state-chartered trust
company formed in 1988. On December 31, 1997, NTQA became a wholly-owned
subsidiary of Northern Trust Corporation. NTQA serves as investment adviser
principally to defined benefit and defined contribution plans and manages over
60 equity and bond commingled and common trust funds. As of December 31, 1997,
Northern Trust Corporation and its subsidiaries had approximately $25.3
billion in assets, $16.4 billion in deposits and employed over 7,553 persons.

Northern and its affiliates administered in various capacities (including as
master trustee, investment manager or custodian) approximately $1 trillion of
assets as of December 31, 1997, including approximately $196.5 billion of
assets for which Northern and its affiliates had investment management
responsibility.     
 
Under its Advisory Agreement with the Trust, each Investment Adviser, subject
to the general supervision of the Trust's Board of Trustees, is responsible
for making investment decisions for the Portfolios for which it serves as
adviser and for placing purchase and sale orders for portfolio securities.
Each Investment Adviser is also responsible for monitoring and preserving the
records required to be maintained under the regulations of the SEC (with
certain exceptions unrelated to its activities for the Trust). As compensation
for its advisory services and its assumption of related expenses, each
Investment Adviser is entitled to a fee from the Portfolios for which it
serves as adviser, computed daily and payable monthly, at annual rates set
forth in the table below (expressed as a percentage of the Portfolio's
respective average daily net assets). The table also reflects the advisory
fees (after voluntary fee waivers) paid by the Portfolios for the fiscal year
ended November 30, 1997.

* Northern has voluntarily agreed to reduce its advisory fee for the Global
 Asset Portfolio to .35% of the Portfolio's average daily net assets for the
 current fiscal year.     
   
Prior to April 1, 1998, Northern served as investment adviser to the U.S.
Treasury Index, Equity Index, Small Company Index and International Equity
Index Portfolios pursuant to advisory agreements substantially identical to
those currently in effect for such Portfolios.     
   
The difference between the stated advisory fee and the actual advisory fees
paid by the Portfolios reflects the fact that the Investment Adviser did not
charge the full amount of the advisory fees to which it would have been
entitled.     
 
Northern also receives compensation as the Trust's custodian and transfer
agent under separate agreements. The fees payable by the Portfolios for these
services are described in this Prospectus under "Summary of Expenses"
 
                                      60

and in the Additional Statement. Different transfer agency fees are payable
with respect to the Class A, B, C and D Shares in the Portfolios.     
   
On September 2, 1997, the shareholders of the International Growth Portfolio
approved a new investment advisory agreement which would allow this Portfolio
to implement a "manager of managers" structure with Northern and one of its
affiliates, and would allow the Portfolio's investment advisers to enter into
sub-advisory agreements with respect to the Portfolio with other firms in the
future without further shareholder approval. This structure cannot be
implemented, however, without an exemptive order of the SEC and final
authorization by the Board of Trustees, and at present it is uncertain when,
or if, this structure will become effective.

YEAR 2000     
   
Like every other business dependent upon computerized information processing,
Northern Trust Corporation ("Northern Trust") must deal with "Year 2000"
issues, which stem from using two digits to reflect the year in computer
programs and data. Computer programmers and other designers of equipment that
use microprocessors have long abbreviated dates by eliminating the first two
digits of the year under the assumption that those two digits will always be
19. As the Year 2000 approaches, many systems may be unable to accurately
process certain date-based information, which could cause a variety of
operational problems for businesses.     
   
Northern Trust's data processing software and hardware provide essential
support to virtually all of its business units, including the units that
provide services to the Trust so successfully addressing Year 2000 issues is
of the highest importance. Failure to complete renovation of the critical
systems used by Northern on a timely basis could have a materially adverse
effect on its ability to provide such services--as could Year 2000 problems
experienced by others. Although the nature of the problem is such that there
can be no complete assurance it will be successfully resolved, Northern Trust
has indicated that a renovation and risk mitigation program is well under way
and that it has a dedicated Year 2000 Project Team whose members have
significant systems

development and maintenance experience. Northern Trust's Year 2000 project
includes a comprehensive testing plan. Northern Trust has advised the Trust
that it expects to complete work on its critical systems by December 31, 1998,
so that testing with outside parties may be conducted during 1999.     
   
Northern Trust also will have a program to monitor and assess the efforts of
other parties. However, it cannot control the success of those efforts.
Contingency plans are being established where appropriate to provide Northern
Trust with alternatives in case these entities experience significant Year 2000
difficulties which impact Northern Trust.     
 
ADMINISTRATOR AND DISTRIBUTOR
 
Goldman Sachs, 85 Broad Street, New York, New York 10004, acts as administrator
and distributor for the Portfolios. As compensation for its administrative
services (which include supervision with respect to the Trust's non-investment
advisory operations) and the assumption of related expenses, Goldman Sachs is
entitled to a fee from each Portfolio, computed daily and payable monthly, at
an annual rate of .15% of the average daily net assets of each of the
International Equity Index, International Growth and International Bond
Portfolios, and .10% of the average daily net assets of each other Portfolio.
No compensation is payable by the Trust to Goldman Sachs for its distribution
services.
   
In addition, Goldman Sachs has agreed that it will reimburse each Portfolio for
its expenses (including the fees payable is Goldman Sachs as administrator, but
excluding the fees payable in Northern for its duties as investment adviser and
transfer agent, servicing fees and extraordinary expenses, such as interest,
taxes and indemnification expenses) which exceed on an annualized basis .25% of
each of the International Bond, International Growth and International Equity
Index Portfolios' average daily net assets and .10% of each other Portfolio's
average daily net assets for any fiscal year. In addition, Northern intends to
voluntarily reduce its advisory fee for the Portfolios during the Trust's
current fiscal year. The result of these reimbursements and fee reductions will
be to increase the performance of the Portfolios during the periods for which
the reimbursements and reductions are made.     
   
SHAREHOLDER SERVICING PLAN     
   
Pursuant to a Shareholder Servicing Plan ("Servicing Plan") adopted by the
Board of Trustees of the Trust, the Trust may enter into agreements ("Servicing
Agreements") with banks, corporations, brokers, dealers and other financial
institutions which may include Northern and its affiliates ("Servicing
Agents"), under which they will render (or arrange for the rendering of)
administrative support services for investors who beneficially own Class B, C
and D Shares of each Portfolio. Beneficial owners of Class C and D Shares
require extensive administrative support services while beneficial owners of
Class B Shares need only some of these services. Administrative support
services, which are described more fully in the Additional Statement, may
include processing purchase and redemption requests from investors, placing net
purchase and redemption orders with Northern acting as the Trust's transfer
agent, providing necessary personnel and facilities to establish and maintain
investor accounts and records, and providing information periodically to
investors showing their positions in Portfolio shares.     
   
For these services, fees are payable by the Trust to Servicing Agents at an
annual rate of up to .10%, .15% and .25% of the average daily net asset value
of Class B Shares, Class C Shares and Class D Shares, respectively, held or
serviced by such Servicing Agents for beneficial shareholders ("Servicing
Fees"). Conflict of interest restrictions may apply to the receipt of
compensation paid by the Trust to a Servicing Agent in connection with     
 
                                       63

the investment of fiduciary funds in Portfolio shares. Banks and other
institutions regulated by the Office of Comptroller of the Currency, Board of
Governors of the Federal Reserve System and state banking commissions, and
investment advisers and other money managers subject to the jurisdiction of
the SEC, the Department of Labor or state securities commissions, are urged to
consult legal counsel before entering into Servicing Agreements.     
 
SERVICE INFORMATION
   
Class A Shares are designed to be purchased by institutional investors or
others who can obtain information about their shareholder accounts and who do
not require the Transfer Agent or Servicing Agent services that are provided
for Class B, C and D shareholders.     
   
Class B Shares are designed to be purchased by organizations maintaining
record ownership on behalf of beneficial owners where certain services of the
Transfer Agent and a Servicing Agent are required that are incident to the
separation of record and beneficial ownership.     
   
Class C Shares are designed to be purchased by institutional investors who
require certain account related services of the Transfer Agent and a Servicing
Agent that are incident to the investor being the beneficial owner of shares.
       
Class D Shares are designed to be purchased by investors having a relationship
with an organization which requires that account related services and
information be provided to the investor and organization by the Transfer Agent
and a Servicing Agent.     
   
Any person entitled to receive compensation for selling or servicing shares of
a Portfolio may receive different compensation with respect to one particular
class of shares over another in the same Portfolio.     
 
EXPENSES
 
Except as set forth above and in the Additional Statement under "Additional
Trust Information," each Portfolio is responsible for the payment of its
expenses. Such expenses include, without limitation, the fees and expenses
payable to Northern and Goldman Sachs, brokerage fees and commissions, fees
for the registration or qualification of Portfolio shares under Federal or
state securities laws, expenses of the organization of the Portfolio, taxes,
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 Trust for violation
of any law, legal, tax and auditing fees and expenses, Servicing Fees,
expenses of preparing and printing prospectuses, statements of additional
information, proxy materials, reports and notices and the printing and
distributing of the same to the Trust's shareholders and regulatory
authorities, compensation and expenses of its Trustees, expenses of industry
organizations such as the Investment Company Institute, miscellaneous expenses
and extraordinary expenses incurred by the Trust.
 
Because the Global Asset Portfolio may invest a substantial portion of its
assets in shares of other investment companies, investors in the Portfolio
will indirectly bear a proportionate share of such investment companies'
operating expenses in addition to those of the Portfolio. See "Special Risks
and Other Considerations Relating to the Global Asset Portfolio" above.

                                   INVESTING
   
PURCHASE OF SHARES     
   
Shares of the Portfolios are sold on a continuous basis by the Trust's
distributor, Goldman Sachs, to institutional investors that either maintain
certain institutional accounts at Northern or its affiliates or invest an
aggregate of at least $5 million in one or more Portfolios of the Trust.
Goldman Sachs has established several procedures for purchasing Portfolio
shares in order to accommodate different types of institutional investors.
       
PURCHASE OF SHARES THROUGH INSTITUTIONAL ACCOUNTS.  Class A, B, C and D Shares
of each Portfolio are offered to Northern, its affiliates and other
institutions and organizations, including certain defined contribution plans
having at least $30 million in assets or annual contributions of at least $5
million (the "Institutions"), acting on behalf of their customers, clients,
employees, participants and others (the "Customers") and for their own
account. Institutions may purchase shares of a Portfolio through procedures
established in connection with the requirements of their institutional
accounts or through procedures set forth herein with respect to Institutions
that invest directly. Institutions should contact Northern or an affiliate for
further information regarding purchases through institutional accounts. There
is no minimum initial investment in the Portfolios for Institutions that
maintain institutional accounts with Northern or its affiliates.     
   
PURCHASE OF SHARES DIRECTLY FROM THE TRUST. An Institution that purchases
shares directly may do so by means of one of the following procedures,
provided that it makes an aggregate minimum initial investment of $5 million
in one or more Portfolios of the Trust:     
     
  PURCHASE BY MAIL. An Institution desiring to purchase shares of a Portfolio
  by mail should mail a check or Federal Reserve draft payable to the
  specific Portfolio together with a completed and signed new account
  application to The Benchmark Funds, c/o The Northern Trust Company, P.O.
  Box 75943, Chicago, Illinois 60675-5943. An application will be incomplete
  if it does not include a corporate resolution with the corporate seal and
  secretary's certification, or other acceptable evidence of authority. If an
  Institution desires to purchase the shares of more than one Portfolio, the
  Institution should send a separate check for each Portfolio. All checks
  must be payable in U.S. dollars and drawn on a bank located in the United
  States. A $20 charge will be imposed if a check does not clear. The Trust
  may delay transmittal of redemption proceeds for shares recently purchased
  by check until such time as it has assured itself that good funds have been
  collected for the purchase of such shares. This may take up to fifteen (15)
  days. Cash and third party checks are not acceptable for the purchase of
  Trust shares.     
     
  PURCHASE BY TELEPHONE. An Institution desiring to purchase shares of a
  Portfolio by telephone should call Northern acting as the Trust's transfer
  agent ("Transfer Agent") at 1-800-637-1380. Please be prepared to identify
  the name of the Portfolio with respect to which shares are to be purchased
  and the manner of payment. Please indicate whether a new account is being
  established or an additional payment is being made to an existing account.
  If an additional payment is being made to an existing account, please
  provide the Institution's name and Portfolio Account Number. Purchase
  orders are effected upon receipt by the Transfer Agent of Federal funds or
  other immediately available funds in accordance with the terms set forth
  below.     
     
  PURCHASE BY WIRE OR ACH TRANSFER. An Institution desiring to purchase
  shares of a Portfolio by wire or ACH Transfer should call the Transfer
  Agent at 1-800-637-1380 for instructions if it is not making an     
 
                                      65
<PAGE>
 
  additional payment to an existing account. An Institution that wishes to
  add to an existing account should wire Federal funds or effect an ACH
  Transfer to:
 
                      The Northern Trust Company
                      Chicago, Illinois
                      ABA Routing No. 0710-00152
                      (Reference 10 Digit Portfolio Account Number)
                         
                      (Reference Shareholder's Name)     
     
  For more information concerning requirements for the purchase of shares,
  call the Transfer Agent at 1-800-637-1380.     
   
EFFECTIVE TIME OF PURCHASES. Except as provided below under "Miscellaneous," a
purchase order for shares received by the Transfer Agent by 3:00 p.m., Chicago
time, on a Business Day (as defined under "Miscellaneous") will be effected on
that Business Day at the net asset value determined on that day with respect
to each Portfolio (other than the Small Company Index and International Equity
Index Portfolios), and at the net asset value plus an additional transaction
fee of .50% and 1.00% of the net asset value determined on that day with
respect to the Small Company Index and International Equity Index Portfolios,
respectively, provided that either: (a) the Transfer Agent receives the
purchase price in Federal funds or other immediately available funds prior to
3:00 p.m., Chicago time, on the same Business Day such order is received; or
(b) payment is received on the next Business Day in the form of Federal funds
or other immediately available funds in an institutional account maintained by
an Institution with Northern or an affiliate. Orders received after 3:00 p.m.
will be effected at the next determined net asset value, provided that payment
is made as provided herein. If an Institution accepts a purchase order from a
Customer on a non-Business Day, the order will not be executed until it is
received and accepted by the Transfer Agent on a Business Day in accordance
with the foregoing procedures.     
   
MISCELLANEOUS PURCHASE INFORMATION. Shares are purchased without a sales
charge imposed by the Trust. The minimum initial investment is $5 million for
Institutions that invest directly in one or more investment portfolios of the
Trust. The Trust reserves the right to waive this minimum and to determine the
manner in which the minimum investment is satisfied. There is no minimum for
subsequent investments.     
   
The Small Company Index and International Equity Index Portfolios require the
payment of an additional transaction fee on purchases of shares of the
Portfolios equal to .50% and 1.00%, respectively, of the dollar amount
invested. The additional transaction fee is paid to the Portfolios, not to
Goldman Sachs or the Investment Adviser. It is not a sales charge. The amount
applies to initial investments in the Portfolios and subsequent purchases
(including purchases made by exchange from the other Portfolios of the Trust),
but not to reinvested dividends or capital gain distributions. The purpose of
the additional transaction fee is to indirectly allocate transaction costs
associated with new purchases to investors making those purchases, thus
protecting existing shareholders. These costs include: (1) brokerage costs;
(2) market impact costs--i.e., the increase in market prices which may result
when the Portfolios purchase thinly traded stocks; (3) sales charges relating
to the purchase of shares in certain unaffiliated investment companies; and,
most importantly, (4) the effect of the "bid-ask" spread in the over-the-
counter market. (Securities in the over-the-counter market are bought at the
"ask" or purchase price, but are valued in the Portfolios at the last quoted
bid price). The additional transaction fees represent the Investment Adviser's
estimate of the brokerage and other transaction costs which may be incurred by
the Small Company Index and International Equity Index Portfolios in acquiring
stocks of small capitalization or foreign     
 
                                      66
<PAGE>
 
   
companies. Without the additional transaction fee, the Portfolios would
generally be selling their shares at a price less than the cost to the
Portfolios of acquiring the portfolio securities necessary to maintain their
investment characteristics, thereby resulting in reduced investment performance
for all shareholders in the Portfolios. With the additional transaction fee,
the transaction costs of acquiring additional stocks are not borne by all
existing shareholders, but are defrayed by the transaction fees paid by those
investors making additional purchases of shares. Because these transaction
costs do not need to be paid out of their other assets, the Small Company Index
and International Equity Index Portfolios are expected to track their
designated indices more closely.     
 
See "Miscellaneous" below for information on when the Trust may advance the
time by which purchase requests must be received.
   
Institutions may impose different minimum investment and other requirements on
Customers purchasing shares through them. Depending on the terms governing the
particular account, Institutions may impose account charges such as asset
allocation fees, account maintenance fees, compensating balance requirements or
other charges based upon account transactions, assets or income which will have
the effect of reducing the net return on an investment in a Portfolio. In
addition, certain Institutions may enter into Servicing Agreements with the
Trust whereby they will perform (or arrange to have performed) various
administrative support services for Customers who are the beneficial owners of
Class B, C and D Shares and receive fees from the Portfolios for such services;
such fees will be borne exclusively by the beneficial owners of Class B, C and
D Shares, respectively. See "Trust Information--Shareholder Servicing Plan."
The level of administrative support services, as well as transfer agency
services, required by an Institution and its Customers generally will determine
whether they purchase shares of Class A, B, C or D. The exercise of voting
rights and the delivery to Customers of shareholder communications from the
Trust will be governed by the Customers' account agreements with the
Institutions. Customers should read this Prospectus in connection with any
relevant agreement describing the services provided by an Institution and any
related requirements and charges, or contact the Institution at which the
Customer maintains its account for further information.     
   
Institutions that purchase shares on behalf of Customers are responsible for
transmitting purchase orders to the Transfer Agent and delivering required
funds on a timely basis. An Institution will be responsible for all losses and
expenses of a Portfolio as a result of a check that does not clear, an ACH
transfer that is rejected, or any other failure to make payment in the time and
manner described above, and Northern may redeem shares from an account it
maintains to protect the Portfolio and Northern against loss. The Trust
reserves the right to reject any purchase order. Federal regulations require
that the Transfer Agent be furnished with a taxpayer identification number upon
opening or reopening an account. Purchase orders without such a number or an
indication that a number has been applied for will not be accepted. If a number
has been applied for, the number must be provided and certified within sixty
days of the date of the order.     
   
Payment for shares of a Portfolio may, in the discretion of Northern, be made
in the form of securities that are permissible investments for the Portfolio.
For further information about the terms of such purchases, see the Additional
Statement.     
   
In the interests of economy and convenience, certificates representing shares
of the Portfolios are not issued.     
 
Institutions investing in the Portfolios on behalf of their Customers should
note that state securities laws regarding the registration of dealers may
differ from the interpretations of Federal law and such Institutions may be
required to register as dealers pursuant to state law.
 
                                       67
<PAGE>
 
   
Northern and NTQA may, at their own expense, provide compensation to certain
dealers and other financial intermediaries who provide services to their
Customers who invest in the Trust or whose Customers purchase significant
amounts of shares of the Trust. The amount of such compensation may be made on
a one-time and/or periodic basis, and may represent all or a portion of the
annual fees that are earned by Northern and NTQA as Investment Advisers (after
adjustments) and are attributable to shares held by such Customers. Such
compensation will not represent an additional expense to the Trust or its
shareholders, since it will be paid from assets of Northern, NTQA or their
affiliates.     
   
REDEMPTION OF SHARES     
   
REDEMPTION OF SHARES THROUGH INSTITUTIONAL ACCOUNTS. Institutions may redeem
shares of a class through procedures established by Northern and its
affiliates in connection with the requirements of their institutional
accounts. Institutions should contact Northern or an affiliate for further
information regarding redemptions through institutional accounts.     
   
REDEMPTION OF SHARES DIRECTLY. Institutions that purchase shares directly from
the Trust through the Transfer Agent may redeem all or part of their Portfolio
shares in accordance with procedures set forth below.     
     
  REDEMPTION BY MAIL. An Institution may redeem shares by sending a written
  request to The Benchmark Funds, c/o The Northern Trust Company, P.O. Box
  75943, Chicago, Illinois 60675-5943. Redemption requests must be signed by
  a duly authorized person, and must state the number of shares or the dollar
  amount to be redeemed and identify the Portfolio Account Number. See "Other
  Requirements."     
     
  REDEMPTION BY TELEPHONE. An Institution may redeem shares by placing a
  redemption order by telephone by calling the Transfer Agent at 1-800-637-
  1380. During periods of unusual economic or market changes, telephone
  redemptions may be difficult to implement. In such event, shareholders
  should follow procedures outlined above under "Redemption by Mail."     
     
  REDEMPTION BY WIRE. If an Institution has given authorization for expedited
  wire redemption, shares can be redeemed and the proceeds sent by Federal
  wire transfer to a single previously designated bank account. The minimum
  amount which may be redeemed by this method is $10,000. The Trust reserves
  the right to change or waive this minimum or to terminate the wire
  redemption privilege. See "Other Requirements."     
     
  TELEPHONE PRIVILEGE. An Institution that has notified the Transfer Agent in
  writing of the Institution's election to redeem or exchange shares by
  placing an order by telephone may do so by calling the Transfer Agent at
  1-800-637-1380. Neither the Trust nor its Transfer Agent will be
  responsible for the authenticity of instructions received by telephone that
  are reasonably believed to be genuine. To the extent that the Trust fails
  to use reasonable procedures to verify the genuineness of telephone
  instructions, it or its service providers may be liable for such
  instructions that prove to be fraudulent or unauthorized. In all other
  cases, the shareholder will bear the risk of loss for fraudulent telephone
  transactions. However, the Transfer Agent has adopted procedures in an
  effort to establish reasonable safeguards against fraudulent telephone
  transactions. The proceeds of redemption orders received by telephone will
  be sent by check, by wire or by transfer pursuant to proper instructions.
  All checks will be made payable to the shareholder of record and mailed
  only to the shareholder's address of record. See "Other Requirements."
  Additionally, the Transfer Agent utilizes recorded lines for telephone
  transactions and retains such tape recordings for six months, and will
  request a form of identification if such identification has been furnished
  to the Transfer Agent or the Trust.     
 
                                      68
<PAGE>
 
     
  OTHER REQUIREMENTS. A change of wiring instructions and a change of the
  address of record may be effected only by a written request to the Transfer
  Agent accompanied by (i) a corporate resolution which evidences authority
  to sign on behalf of the Institution (including the corporate seal and
  secretary's certification, (ii) a signature guarantee by a financial
  institution that is a participant in the Stock Transfer Agency Medallion
  Program ("STAMP") in accordance with rules promulgated by the SEC (a
  signature notarized by a notary public is not acceptable) or (iii) such
  other evidence of authority as may be acceptable to the Transfer Agent. A
  redemption request by mail will not be effective unless signed by a person
  authorized by the corporate resolution or other acceptable evidence of
  authority on file with the Transfer Agent.     
   
EXCHANGE PRIVILEGE. Institutions and, to the extent permitted by their account
agreements, Customers, may, after appropriate prior authorization, exchange
Class A, B, C or D Shares of a Portfolio having a value of at least $1,000 for
Class A, B, C or D Shares, respectively, of other portfolios of the Trust as
to which the Institution or Customer maintains an existing account with an
identical title.     
   
Exchanges will be effected by a redemption of Class A, B, C or D Shares of the
Portfolio held and the purchase of shares of the portfolio acquired. Customers
of Institutions should contact their Institutions for further information
regarding the Trust's exchange privilege and Institutions should contact the
Transfer Agent as appropriate. The Trust reserves the right to modify or
terminate the exchange privilege at any time upon 60 days written notice to
shareholders of record and to reject any exchange request. Exchanges are only
available in states where an exchange can legally be made.     
   
EFFECTIVE TIME OF REDEMPTIONS AND EXCHANGES. Redemption orders of Portfolio
shares are effected at the net asset value per share next determined after
receipt in good order by the Transfer Agent. Good order means that the request
includes the following: the account number and Portfolio name; the amount of
the transaction (as specified in dollars or shares); and the signature of a
duly authorized person (except for telephone and wire redemptions). See
"Investing--Redemption of Shares--Other Requirements." Exchange orders
involving the purchase of shares of the Small Company Index Portfolio and
International Equity Index Portfolio are effected at the net asset value per
share next determined after receipt in good order by the Transfer Agent plus
an additional transaction fee equal to .50% and 1.00%, respectively, of such
value. See "Purchase of Shares--Miscellaneous Purchase Information" above.
Exchange orders of the other Portfolios are effected at the net asset value
per share next determined after receipt in good order by the Transfer Agent.
If received by Northern with respect to an institutional account it maintains
or the Transfer Agent by 3:00 p.m., Chicago time, on a Business Day, a
redemption request normally will result in proceeds being credited to such
account or sent on the next Business Day. Proceeds for redemption orders
received on a non-Business Day will normally be sent on the second Business
Day after receipt in good order.     
   
MISCELLANEOUS REDEMPTION AND EXCHANGE INFORMATION. All redemption proceeds
will be sent by check unless Northern is directed otherwise. The ACH system
may be utilized for payment of redemption proceeds. Redemption of shares may
not be effected if a shareholder has failed to submit a completed and properly
executed (with corporate resolution or other acceptable evidence of authority)
new account application. If shares to be redeemed were recently purchased by
check, the Trust may delay transmittal of redemption proceeds until such time
as it has assured itself that good funds have been collected for the purchase
of such shares. This may take up to fifteen (15) days. The Trust reserves the
right to defer crediting, sending or wiring redemption proceeds for up to
seven days after receiving the redemption order if, in its judgment, an
earlier payment could adversely affect a Portfolio.     
 
                                      69
<PAGE>
 
   
See "Miscellaneous" below for information on when the Trust may advance the
time by which redemption and exchange requests must be received.     
 
The Trust may require any information reasonably necessary to ensure that a
redemption has been duly authorized.
   
It is the responsibility of Institutions acting on behalf of Customers to
transmit redemption orders to the Transfer Agent and to credit Customers'
accounts with the redemption proceeds on a timely basis. If a Customer has
agreed with a particular Institution to maintain a minimum balance in his
account at such Institution and the balance in such account falls below that
minimum, such Customer may be obliged to redeem all or part of his shares to
the extent necessary to maintain the required minimum balance. The Trust also
reserves the right to redeem shares held by any shareholder who provides
incorrect or incomplete account information or when such involuntary
redemptions are necessary to avoid adverse consequences to the Trust and its
shareholders.     
 
DISTRIBUTIONS
 
Distributions from a Portfolio's net investment income and annualized capital
gains are made as follows:

Dividends and distributions will reduce a Portfolio's net asset value by the
amount of the dividend or distribution. All dividends and distributions are
automatically reinvested (without any sales charge or additional purchase
price amount) in additional shares of the same Portfolio at their net asset
value per share determined on the payment date. However, a holder may elect,
upon written notification to the Transfer Agent, to have dividends or capital
gain distributions (or both) paid in cash or reinvested in the same class of
shares of another Portfolio at their net asset value per share (plus an
additional purchase price amount equal to .50% and 1.00% of the amount
invested in the case of the Small Company Index Portfolio and International
Equity Index Portfolio, respectively) determined on the payment date (provided
the holder maintains an account in such Portfolio). Shareholders of record
must make such election, or any revocation thereof, in writing to the Transfer
Agent. The election will become effective with respect to dividends paid two
days after its receipt by the Transfer Agent.     
 
                                      70
<PAGE>
 
   
Net loss, if any, from certain foreign currency transactions or instruments
that is otherwise taken into account with respect to the Global Asset,
International Bond, International Growth and International Equity Index
Portfolios in calculating net investment income or net realized capital gains
for accounting purposes may not be taken into account in determining the
amount of dividends to be declared and paid, with the result that a portion of
the Portfolios' dividends may be treated as a return of capital, nontaxable to
the extent of a shareholder's tax basis in his shares.     
   
Because of the different servicing fees and transfer agency fees payable with
respect to the Class A, B, C and D Shares in a Portfolio, the amount of such
Portfolio's net investment income available for distribution to the holders of
such shares will be effectively reduced by the amount of such fees. See
"Shareholder Service Plan" and "Investment Adviser, Transfer Agent and
Custodian" under the heading "Trust Information" in this Prospectus.     
 
TAXES
 
Each Portfolio intends to qualify as a separate "regulated investment company"
under the Internal Revenue Code of 1986, as amended (the "Code"). Such
qualification generally will relieve the Portfolios of liability for Federal
income taxes to the extent their earnings are distributed in accordance with
the Code.
   
Qualification as a regulated investment company under the Code for a taxable
year requires, among other things, that each Portfolio distribute to its
shareholders an amount equal to at least 90% of its investment company taxable
income for such year. In general, a Portfolio's investment company taxable
income will be its taxable income, subject to certain adjustments and
excluding the excess of any net long-term capital gain for the taxable year
over the net short-term capital loss, if any, for such year. Each Portfolio
intends to distribute as dividends substantially all of its investment company
taxable income each year. Such dividends will be taxable as ordinary income to
the Portfolio's shareholders who are not currently exempt from Federal income
taxes whether they are received in cash or reinvested in additional shares.
(Federal income taxes for distributions to an IRA or other qualified
retirement plan are deferred or eliminated under the Code.) Such ordinary
income distributions will qualify for the dividends received deduction for
corporations to the extent of the total qualifying dividends received by the
distributing Portfolio from domestic corporations for the taxable year. It is
not expected that any Fixed Income Portfolio distributions will qualify for
the dividends received deduction for corporations.     
   
Substantially all of each Portfolio's net realized long-term capital gains
(including 28% rate gains) will be distributed at least annually to its
shareholders. The Portfolios generally will have no tax liability with respect
to such gains and the distributions will be taxable to Portfolio shareholders
who are not currently exempt from Federal income taxes as long-term capital
gains (20% or 28% rate gain, depending upon the breakdown of the Portfolio's
long-term capital gain), regardless of how long the shareholders have held the
shares and whether such gains are received in cash or reinvested in additional
shares. Shareholders should note that, upon sale or exchange of Portfolio
shares, if the shareholder has not held such shares for more than six months,
any loss on the sale or exchange of those shares will be treated as long term
capital loss to the extent of the capital gain dividends received with respect
to the shares.     
   
Dividends declared in October, November or December of any year payable to
shareholders of record on a specified date in such months will be deemed for
Federal tax purposes to have been paid by the Portfolio and received by the
shareholders on December 31 of such year if such dividends are paid during
January of the following year.     
 
                                      71
<PAGE>
 
   
An investor considering buying shares of a Portfolio on or just before the
record date of a dividend should be aware that the amount of the forthcoming
dividend payment, although in effect a return of capital, will be taxable.
       
A taxable gain or loss may be realized by a shareholder upon the redemption,
transfer or exchange of shares of a Portfolio depending upon the tax basis and
their price at the time of redemption, transfer or exchange.     
   
It is expected that dividends and certain interest income earned by the
International Bond, International Growth and International Equity Index
Portfolios from foreign securities will be subject to foreign withholding
taxes or other taxes. So long as more than 50% of the value of the Portfolios'
total assets at the close of any taxable year consists of stock or securities
(including debt securities) of foreign corporations, the Portfolios may elect,
for Federal income tax purposes, to treat certain foreign taxes paid by them,
including generally any withholding taxes and other foreign income taxes, as
paid by their shareholders. Should the Portfolios make this election, the
amount of such foreign taxes paid by the Portfolios will be included in their
shareholders' income pro rata (in addition to taxable distributions actually
received by them), and such shareholders will be entitled either (a) to credit
their proportionate amounts of such taxes against their Federal income tax
liabilities, or (b) to deduct such proportionate amounts from their Federal
taxable income under certain circumstances.     
   
The Global Asset Portfolio may invest in the International Bond, International
Equity Index and International Growth Portfolios which expect to be eligible
to make the above-described election. While the Global Asset Portfolio will be
able to deduct the foreign taxes that it will be treated as receiving 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 Global Asset Portfolio will not have the option of claiming a foreign tax
credit for foreign taxes paid by the International Bond, International Equity
Index and International Growth Portfolios, while persons who invest directly
in such underlying Portfolios may have that option.     
   
If the Global Asset, International Bond, International Growth and
International Equity Index Portfolios invest in certain "passive foreign
investment companies" ("PFICs"), they will be subject to Federal income tax
(and possibly additional interest charges) on a portion of any "excess
distribution" or gain from the disposition of such investments, even if they
distribute such income to their shareholders. If a Portfolio elects to treat
the PFIC as a "qualified electing fund" ("QEF") and the PFIC furnishes certain
financial information in the required form, a Portfolio would instead be
required to include in income each year its allocable share of the ordinary
earnings and net capital gains of the QEF, regardless of whether such income
is received, and such amounts would be subject to the various distribution
requirements described above. In addition, effective for the tax years
beginning after 1997, a Portfolio may elect instead to recognize any
appreciation in the PFIC shares that it owns by marking them to market as of
the last Business Day of each taxable year. Again, gain recognized under this
"mark-to-market" approach would be subject to the various distribution
requirements described above, even if no cash is received currently from the
PFIC investment.     
   
Shareholders of record will be advised by the Trust at least annually as to
the Federal income tax consequences of distributions made to them each year.
       
The foregoing discussion summarizes some of the important Federal tax
considerations generally affecting the Portfolios and their shareholders and
is not intended as a substitute for careful tax planning. Accordingly,
potential investors in the Portfolios should consult their tax advisers with
specific reference to their own Federal, state and local tax situation.

                                NET ASSET VALUE
   
The net asset value per share of each Portfolio for purposes of pricing
purchase and redemption orders is calculated by Northern as of 3:00 p.m.,
Chicago Time, on each Business Day. The time at which the net asset value per
share of a Portfolio is calculated may be advanced on days on which Northern
or the securities markets close early. See "Miscellaneous" below. Net asset
value per share of a particular class in a Portfolio is calculated by dividing
the value of all securities and other assets belonging to a Portfolio that are
allocated to such class, less the liabilities charged to that class, by the
number of the outstanding shares of that class. Because the Global Asset
Portfolio expects to invest a substantial portion of its assets in the
Benchmark Portfolios and other funds, the Portfolio's net asset value per
share will fluctuate with changes in the per share value of such other
investment portfolios.     
   
U.S. and foreign investments held by a Portfolio are valued at the last quoted
sales price on the exchange on which such securities are primarily traded,
except that securities listed on an exchange in the United Kingdom are valued
at the average of the closing bid and ask prices. If any securities listed on
a U.S. securities exchange are not traded on a valuation date, they will be
valued at the last quoted bid price. If securities listed on a foreign
securities exchange are not traded on a valuation date, they will be valued at
the most recent quoted trade price. Securities which are traded in the U.S.
over-the-counter markets are valued at the last quoted bid price. Securities
which are traded in the foreign over-the-counter markets are valued at the
last sales price, except that such securities traded in the United Kingdom are
valued at the average of the closing bid and ask prices. Shares of investment
companies held by the Portfolios will be valued at their respective net asset
values. Any securities, including restricted securities, for which current
quotations are not readily available are valued at fair value as determined in
good faith by the Investment Adviser under the supervision of the Board of
Trustees. Short-term investments are valued at amortized cost which the
Investment Adviser has determined, pursuant to Board authorization,
approximates market value. Securities may be valued on the basis of prices
provided by independent pricing services when such prices are believed to
reflect the fair market value of such securities.     
 
                            PERFORMANCE INFORMATION
   
The performance of a class of shares of a Portfolio may be compared to those
of other mutual funds with similar investment objectives and to bond, stock
and other relevant indices or to rankings prepared by independent services or
other financial or industry publications that monitor the performance of
mutual funds. For example, the performance of a class of shares may be
compared to data prepared by Lipper Analytical Services, Inc. or other
independent mutual fund reporting services. In addition, the performance of a
class may be compared to the Lehman Brothers Government/Corporate Bond Index
(or its components, including the Treasury Bond Index), S&P Index, S&P/Barra
Growth Index, the Russell Index, the EAFE Index or other unmanaged stock and
bond indices, including, but not limited to, the Merrill Lynch 1-5 Year
Government Bond Index, the Merrill Lynch 1-5 Year Corporate/Government Bond
Index, the 3-month LIBOR Index, the 91-day Treasury Bill Rate, the Composite
Index, the J.P. Morgan Non-U.S. Government Bond Index, and the Dow Jones
Industrial Average, a recognized unmanaged index of common stocks of 30
industry companies listed on the New York Stock Exchange. Performance data as
reported in national financial publications such as Money Magazine,
Morningstar, Forbes, Barron's, The Wall Street Journal and The New York Times,
or in publications of a local or regional nature, may also be used in
comparing the performance of a class of shares of a Portfolio.     
 
                                      73
<PAGE>
 
   
The Portfolios calculate their total returns for each class of shares on an
"average annual total return" basis for various periods from the dates the
respective Portfolios commenced investment operations and for other periods as
permitted under the rules of the SEC. Average annual total return reflects the
average annual percentage change in value of an investment in the class over
the measuring period. Total returns for each class of shares may also be
calculated on an "aggregate total return" basis for various periods. Aggregate
total return reflects the total percentage change in value over the measuring
period. Both methods of calculating total return reflect changes in the price
of the shares and assume that any dividends and capital gain distributions
made by the Portfolio with respect to a class during the period are reinvested
in the shares of that class. When considering average total return figures for
periods longer than one year, it is important to note that the annual total
return of a class for any one year in the period might have been more or less
than the average for the entire period. The Portfolios may also advertise from
time to time the total return of one or more classes of shares on a year-by-
year or other basis for various specified periods by means of quotations,
charts, graphs or schedules.     
   
The yield of a class of shares in the Fixed Income Portfolios, the Balanced
Portfolio and the Global Asset Portfolio is computed based on the net income
of such class during a 30-day (or one month) period (which period will be
identified in connection with the particular yield quotation). More
specifically, a Portfolio's yield for a class of shares is computed by
dividing the per share net income for the class during a 30-day (or one month)
period by the net asset value per share on the last day of the period and
annualizing the result on a semi-annual basis.     
   
The Small Company Index and International Equity Index Portfolios may
advertise total return data without reflecting the .50% and 1.00% portfolio
transaction fee in accordance with the rules of the SEC. Quotations which do
not reflect the fee will, of course, be higher than quotations which do.     
   
Because of the different servicing fees and transfer agency fees payable with
respect to the Class A, B, C and D Shares in a Portfolio, the performance of
such shares will be effectively reduced by the amount of such fees. For
example, because Class A Shares bear the lowest servicing and transfer agency
fees, the return of Class A Shares will be more than the return of other
classes of shares of the same Portfolio. See "Shareholder Servicing Plan" and
"Investment Adviser, Transfer Agent and Custodian" under the heading "Trust
Information" in this Prospectus.     
   
The performance of each class of shares of the Portfolios is based on
historical earnings, will fluctuate and is not intended to indicate future
performance. The investment return and principal value of an investment in a
class will fluctuate so that when redeemed, shares may be worth more or less
than their original cost. Performance data may not provide a basis for
comparison with bank deposits and other investments which provide a fixed
yield for a stated period of time. Total return data should also be considered
in light of the risks associated with a Portfolio's composition, quality,
maturity, operating expenses and market conditions. Any fees charged by
Institutions directly to their Customer accounts in connection with
investments in a Portfolio will not be included in calculations of performance
data.

                                 ORGANIZATION
   
Each Portfolio is a series of The Benchmark Funds, which was formed as a
Delaware business trust on July 1, 1997 under an Agreement and Declaration of
Trust. The Portfolios were formerly series of The Benchmark Funds, a
Massachusetts business trust, which were reorganized into the Trust on March
31, 1998. As of the date of this Prospectus, the Trust has created eighteen
separate series of shares of beneficial interest representing interests in
eighteen investment portfolios, fourteen of which are described in this
Prospectus; the other series of shares are described in separate prospectuses.
The business and affairs of the Trust are managed by or under the direction of
its Board of Trustees. The Declaration of Trust of the Trust authorizes the
Board of Trustees to create and classify shares of beneficial interest in
separate series, without further action by shareholders. Additional series may
be added in the future. The Trustees also have authority to classify or
reclassify any unissued shares into additional series or classes within a
series. Pursuant to such authority, the Board of Trustees has classified four
classes of shares in each Portfolio: the Class A Shares, Class B Shares, Class
C Shares and Class D Shares. Each share of a Portfolio is without par value,
represents an equal proportionate interest in that Portfolio with each other
share of its class in that Portfolio and is entitled to such dividends and
distributions earned on such Portfolio's assets as are declared in the
discretion of the Board of Trustees.     
   
The Trust's shareholders are entitled at the discretion of the Board of
Trustees to vote either on the basis of the number of shares held or the
aggregate net asset value represented by such shares. Each series entitled to
vote on a matter will vote thereon in the aggregate and not by series, except
as otherwise required by law or when the matter to be voted on affects only
the interests of shareholders of a particular series. The Additional Statement
gives examples of situations in which the law requires voting by series.
Voting rights are not cumulative and, accordingly, the persons holding more
than 50% of the aggregate voting power of the Trust may elect all of the
Trustees irrespective of the vote of the other shareholders. In addition,
holders of each of the Class A, B, C and D shares representing interests in
the same Portfolio have equal voting rights except that only shares of a
particular class within the Portfolio will be entitled to vote on matters
submitted to a vote of shareholders (if any) relating to shareholder servicing
expenses and transfer agency fees that are payable by that class.     
   
As of February 28, 1998, Northern possessed sole or shared voting or
investment power for its customer accounts with respect to more than 50% of
the outstanding shares of the Trust.     
   
The Trust does not presently intend to hold annual meetings of shareholders
except as required by the 1940 Act or other applicable law. The Trustees will
promptly call a meeting of shareholders to vote upon the removal of any
Trustee when so requested in writing by the record holders of 10% or more of
the outstanding shares. To the extent required by law, the Trust will assist
in shareholder communications in connection with such a meeting.     
   
The Trust Agreement provides that each shareholder, by virtue of becoming
such, will be held to have expressly assented and agreed to the terms of the
Trust Agreement and to have become a party thereto.

                                 MISCELLANEOUS
 
The address of the Trust is 4900 Sears Tower, Chicago, Illinois 60606 and the
telephone number is (800) 621-2550.
   
When a shareholder moves, the shareholder is responsible for sending written
notice to the Trust of any new mailing address. The Trust and its transfer
agent may charge a shareholder their reasonable costs in locating a
shareholder's current address in accordance with SEC regulations.     
   
As used in this Prospectus, the term "Business Day" refers to each day when
Northern and the New York Stock Exchange are open, which is Monday through
Friday, except for holidays observed by Northern and/or the Exchange other
than Good Friday. For 1998 the holidays of Northern and/or the Exchange are:
New Year's Day, Dr. Martin Luther King, Jr. Day, Presidents' Day, Memorial
Day, Independence Day, Labor Day, Columbus Day, Veteran's Day, Thanksgiving
and Christmas Day. On those days when Northern or the Exchange closes early as
a result of unusual weather or other circumstances, the Portfolios reserve the
right to advance the time on that day by which purchase, redemption and
exchange requests must be received. In addition, on any Business Day when The
Bond Market Association recommends that the securities markets close or close
early, the Portfolios reserve the right to cease or to advance the deadline
for accepting purchase, redemption and exchange orders for same Business Day
credit. Purchase, redemption and exchange requests received after the advanced
closing time will be effected on the next Business Day. Each Portfolio
reserves, however, the right to reject any purchase order and also to defer
crediting, sending or wiring redemption proceeds for up to seven days after
receiving a redemption order if, in its judgment, an earlier payment would
adversely affect such Portfolio. See "Investing--Purchase of Shares" and
"Investing--Redemption of Shares" above for more information.

Prospective investors in the Global Asset Portfolio should note that the Trust
has filed an application with the Securities and Exchange Commission requesting
an exemption from certain provisions of the 1940 Act to allow the Portfolio to
conduct its investment operations as described in its Prospectus.  As of the
date of this Additional Statement, the requested exemption had not been granted,
and there is no assurance that it will be.  No shares of the Portfolio will be
sold unless and until the requested exemption is granted.

                       ADDITIONAL INVESTMENT INFORMATION

INVESTMENT OBJECTIVES AND POLICIES

    
     The following supplements the investment objectives and policies of the
Balanced, Global Asset, Equity Index, Diversified Growth, Focused Growth, Small
Company Index, International Equity Index, and International Growth Portfolios
(the "Portfolios") of The Benchmark Funds (the "Trust") as set forth in the
Prospectus.     

     Warrants.  The Balanced, Global Asset, Diversified Growth, Focused Growth,
     --------                                                                  
Small Company Index, International Equity Index and International Growth
Portfolios may purchase warrants and similar rights, which are privileges issued
by corporations enabling the owners to subscribe to and purchase a specified
number of shares of the corporation at a specified price during a specified
period of time.  The purchase of warrants involves the risk that a Portfolio
could lose the purchase value of a warrant if the right to subscribe to
additional shares is not exercised prior to the warrant's expiration.  Also, the
purchase of warrants involves the risk that the effective price paid for the
warrant added to the subscription price of the related security may exceed the
value of the subscribed security's market price such as when there is no
movement in the level of the underlying security.  A Portfolio will not invest
more than 5% of its total assets, taken at market value, in warrants. Warrants
acquired by a Portfolio in shares or attached to other securities are not
subject to this restriction.

    
     U.S. Government Obligations.  Examples of the types of U.S. Government
     ---------------------------                                           
obligations that may be acquired by the Portfolios include U.S. Treasury Bills,
Treasury Notes and Treasury Bonds and the obligations of Federal Home Loan
Banks, Federal Farm Credit Banks, Federal Land Banks, the Federal Housing
Administration, Farmers Home Administration, Export-Import Bank of the United
States, Small Business Administration, General Services Administration, Central
Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal
Intermediate Credit Banks, and the Maritime Administration.     

     Foreign Securities.  Unanticipated political or social developments may
     ------------------                                                     
affect the value of a Portfolio's investments in emerging market countries and
the availability to a Portfolio of additional investments in those countries.
The small size and inexperience of the securities markets in certain of such
countries and the limited volume of trading in securities in those countries may
make a Portfolio's investments in such countries illiquid and more volatile than
investments in Japan or most Western European countries, and a Portfolio may be
required to establish special custodial or other arrangements before making
certain investments in those countries.  There may be little financial or
accounting information available with respect to issuers located in certain of

                                      B-3    
<PAGE>
 
such countries, and it may be difficult as a result to assess the value or
prospects of an investment in such issuers.

Investors should understand that the expense ratios of the International Equity
Index and International Growth Portfolios can be expected to be higher than
those funds investing primarily in domestic securities.  The costs attributable
to investing abroad are usually higher for several reasons, such as the higher
cost of investment research, higher cost of custody of foreign securities,
higher commissions paid on comparable transactions on foreign markets and
additional costs arising from delays in settlements of transactions involving
foreign securities.

     Foreign Currency Transactions.  In order to protect against a possible loss
     -----------------------------                                              
on investments resulting from a decline or appreciation in the value of a
particular foreign currency against the U.S. dollar or another foreign currency
or for other reasons, the Balanced, Global Asset, Diversified Growth, Focused
Growth, International Equity Index and International Growth Portfolios are
authorized to enter into forward foreign currency exchange contracts.  These
contracts involve an obligation to purchase or sell a specified currency at a
future date at a price set at the time of the contract. Forward currency
contracts do not eliminate fluctuations in the values of portfolio securities
but rather allow a Portfolio to establish a rate of exchange for a future point
in time.

     When entering into a contract for the purchase or sale of a security, a
Portfolio may enter into a forward foreign currency exchange contract for the
amount of the purchase or sale price to protect against variations, between the
date the security is purchased or sold and the date on which payment is made or
received, in the value of the foreign currency relative to the U.S. dollar or
other foreign currency.

    
     When an Investment Adviser anticipates that a particular foreign currency
may decline substantially relative to the U.S. dollar or other leading
currencies, in order to reduce risk, a Portfolio may enter into a forward
contract to sell, for a fixed amount, the amount of foreign currency
approximating the value of some or all of the Portfolio's securities denominated
in such foreign currency.  Similarly, when the securities held by a Portfolio
create a short position in a foreign currency, the Portfolio may enter into a
forward contract to buy, for a fixed amount, an amount of foreign currency
approximating the short position.  With respect to any forward foreign currency
contract, it will not generally be possible to match precisely the amount
covered by that contract and the value of the securities involved due to the
changes in the values of such securities resulting from market movements between
the date the forward contract is entered into and the date it matures.  In
addition, while forward contracts may offer protection from losses resulting
from declines or     

                                      B-4    
<PAGE>
 
appreciation in the value of a particular foreign currency, they also limit
potential gains which might result from changes in the value of such currency.
A Portfolio may also incur costs in connection with forward foreign currency
exchange contracts and conversions of foreign currencies and U.S. dollars.

     In addition, with respect to the Global Asset and International Growth
Portfolios, Northern may purchase or sell forward foreign currency exchange
contracts to seek to increase total return.

    
     Liquid assets equal to the amount of a Portfolio's assets that could be
required to consummate forward contracts will be segregated except to the extent
the contracts are otherwise "covered."  The segregated assets will be valued at
market or fair value.  If the market or fair value of such assets declines,
additional liquid assets will be segregated daily so that the value of the
segregated assets will equal the amount of such commitments by the Portfolio.  A
forward contract to sell a foreign currency is "covered" if a Portfolio owns the
currency (or securities denominated in the currency) underlying the contract, or
holds a forward contract (or call option) permitting the Portfolio to buy the
same currency at a price that is (i) no higher than the Portfolio's price to
sell the currency or (ii) greater than the Portfolio's price to sell the
currency provided the Portfolio segregates liquid assets in the amount of the
difference.  A forward contract to buy a foreign currency is "covered" if a
Portfolio holds a forward contract (or call option) permitting the Portfolio to
sell the same currency at a price that is (i) as high as or higher than the
Portfolio's price to buy the currency or (ii) lower than the Portfolio's price
to buy the currency provided the Portfolio segregates liquid assets in the
amount of the difference.     

     Options.  Each Portfolio may buy put options and buy call options and write
     -------                                                                    
covered call and secured put options.  Such options may relate to particular
securities, foreign and domestic stock indices, financial instruments, or
foreign currencies and may or may not be listed on a domestic or foreign
securities exchange or issued by the Options Clearing Corporation.  Options
trading is a highly specialized activity which entails greater than ordinary
investment risk.  Options on particular securities may be more volatile than the
underlying instruments, and therefore, on a percentage basis, an investment in
options may be subject to greater fluctuation than an investment in the
underlying instruments themselves.

     The Portfolios will write call options only if they are "covered."  In the
case of a call option on a security or currency, the option is "covered" if a
Portfolio owns the security or currency underlying the call or has an absolute
and immediate right to acquire that security or currency without additional cash
consideration (or, if additional cash consideration is required,

                                      B-5    
<PAGE>
 
    
liquid assets in such amount are segregated) upon conversion or exchange of
other securities held by it.  For a call option on an index, the option is
covered if a Portfolio maintains with its custodian a portfolio of securities
substantially replicating the movement of the index, or liquid assets equal to
the contract value.  A call option is also covered if a Portfolio holds a call
on the same security, currency or index as the call written where the exercise
price of the call held is (i) equal to or less than the exercise price of the
call written, or (ii) greater than the exercise price of the call written
provided the Portfolio segregates liquid assets in the amount of the difference.
The Portfolios will write put options only if they are "secured" by segregated
liquid assets in an amount not less than the exercise price of the option at all
times during the option period.     

    
     A Portfolio's obligation to sell a security subject to a covered call
option written by it, or to purchase a security or currency subject to a secured
put option written by it, may be terminated prior to the expiration date of the
option by the Portfolio's execution of a closing purchase transaction, which is
effected by purchasing on an exchange an option of the same series (i.e., same
underlying security or currency, exercise price and expiration date) as the
option previously written.  Such a purchase does not result in the ownership of
an option.  A closing purchase transaction will ordinarily be effected to
realize a profit on an outstanding option, to prevent an underlying security or
currency from being called, to permit the sale of the underlying security or
currency or to permit the writing of a new option containing different terms on
such underlying security.  The cost of such a liquidation purchase plus
transaction costs may be greater than the premium received upon the original
option, in which event the Portfolio will have incurred a loss in the
transaction.  There is no assurance that a liquid secondary market will exist
for any particular option.  An option writer, unable to effect a closing
purchase transaction, will not be able to sell the underlying security or
currency (in the case of a covered call option) or liquidate the segregated
assets (in the case of a secured put option) until the option expires or the
optioned security or currency is delivered upon exercise with the result that
the writer in such circumstances will be subject to the risk of market decline
or appreciation in the security or currency during such period.     

     When a Portfolio purchases an option, the premium paid by it is recorded as
an asset of the Portfolio.  When the Portfolio writes an option, an amount equal
to the net premium (the premium less the commission) received by the Portfolio
is included in the liability section of the Portfolio's statement of assets and
liabilities as a deferred credit.  The amount of this asset or deferred credit
will be subsequently marked-to-market to reflect the current value of the option
purchased or written.  The current value of the traded option is the last sale
price or, in the absence of a sale, the current bid price.  If an option
purchased

                                      B-6    
<PAGE>
 
by the Portfolio expires unexercised the Portfolio realizes a loss equal to the
premium paid.  If the Portfolio enters into a closing sale transaction on an
option purchased by it, the Portfolio will realize a gain if the premium
received by the Portfolio on the closing transaction is more than the premium
paid to purchase the option, or a loss if it is less.  If an option written by
the Portfolio expires on the stipulated expiration date or if the Portfolio
enters into a closing purchase transaction, it will realize a gain (or loss if
the cost of a closing purchase transaction exceeds the net premium received when
the option is sold) and the deferred credit related to such option will be
eliminated.  If an option written by the Portfolio is exercised, the proceeds of
the sale will be increased by the net premium originally received and the
Portfolio will realize a gain or loss.

     There are several risks associated with transactions in certain options.
For example, there are significant differences between the securities, currency
and options markets that could result in an imperfect correlation between these
markets, causing a given transaction not to achieve its objectives.  In
addition, a liquid secondary market for particular options, whether traded over-
the-counter or on a national securities exchange ("Exchange") may be absent for
reasons which include the following: there may be insufficient trading interest
in certain options; restrictions may be imposed by an Exchange on opening
transactions or closing transactions or both; trading halts, suspensions or
other restrictions may be imposed with respect to particular classes or series
of options or underlying securities or currencies; unusual or unforeseen
circumstances may interrupt normal operations on an Exchange; the facilities of
an Exchange or the Options Clearing Corporation may not at all times be adequate
to handle current trading value; or 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 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.

     Supranational Bank Obligations.  The Balanced and Global Asset Portfolios
     ------------------------------                                           
may invest in obligations of supranational banks.  Supranational banks are
international banking institutions designed or supported by national governments
to promote economic reconstruction, development or trade between nations (e.g.,
the World Bank).  Obligations of supranational banks may be supported by
appropriated but unpaid commitments of their member countries and there is no
assurance that these commitments will be undertaken or met in the future.

     Stripped Securities.  The Balanced and Global Asset Portfolios may purchase
     -------------------                                                        
stripped securities.  The Treasury Department has

                                      B-7    
<PAGE>
 
facilitated transfers of ownership of zero coupon securities by accounting
separately for the beneficial ownership of particular interest coupon and
principal payments on Treasury securities through the Federal Reserve book-entry
record-keeping system.  The Federal Reserve program as established by the
Treasury Department is known as "STRIPS" or "Separate Trading of Registered
Interest and Principal of Securities." The Portfolios may purchase securities
registered in the STRIPS program.  Under the STRIPS program, each Portfolio will
be able to have its beneficial ownership of zero coupon securities recorded
directly in the book-entry record-keeping system in lieu of having to hold
certificates or other evidences of ownership of the underlying U.S. Treasury
securities.

     In addition, the Balanced and Global Asset Portfolios may acquire U.S.
Government obligations and their unmatured interest coupons that have been
separated ("stripped") by their holder, typically a custodian bank or investment
brokerage firm.  Having separated the interest coupons from the underlying
principal of the U.S.  Government obligations, the holder will resell the
stripped securities in custodial receipt programs with a number of different
names, including "Treasury Income Growth Receipts" ("TIGRs") and "Certificate of
Accrual on Treasury Securities" ("CATS").  The stripped coupons are sold
separately from the underlying principal, which is usually sold at a deep
discount because the buyer receives only the right to receive a future fixed
payment on the security and does not receive any rights to periodic interest
(cash) payments.  The underlying U.S. Treasury bonds and notes themselves are
held in book-entry form at the Federal Reserve Bank or, in the case of bearer
securities (i.e., unregistered securities which are ostensibly owned by the
bearer or holder), in trust on behalf of the owners.  Counsel to the
underwriters of these certificates or other evidences of ownership of U.S.
Treasury securities have stated that, in their opinion, purchasers of the
stripped securities most likely will be deemed the beneficial holders of the
underlying U.S.  Government obligations for Federal tax purposes. The Trust is
not aware of any binding legislative, judicial or administrative authority on
this issue.

     The Prospectus discusses other types of stripped securities that may be
purchased by the Portfolios, including stripped mortgage-backed securities
("SMBS"). SMBS are usually structured with two or more classes that receive
different proportions of the interest and principal distributions from a pool of
mortgage-backed obligations. A common type of SMBS will have one class receiving
all of the interest, while the other class receives all of the principal.
However, in some instances, one class will receive some of the interest and most
of the principal while the other class will receive most of the interest and the
remainder of the principal. If the underlying obligations experience greater
than anticipated prepayments of principal, a Portfolio may fail to fully recoup
its initial investment in these securities. The market value

                                      B-8    
<PAGE>
 
of the class consisting entirely of principal payments generally is extremely
volatile in response to changes in interest rates. The yields on a class of SMBS
that receives all or most of the interest are generally higher than prevailing
market yields on other mortgage-backed obligations because their cash flow
patterns are also volatile and there is a risk that the initial investment will
not be fully recouped. SMBS issued by the U.S. Government (or a U.S. Government
agency or instrumentality) may be considered liquid under guidelines established
by the Trust's Board of Trustees if they can be disposed of promptly in the
ordinary course of business at a value reasonably close to that used in the
calculation of the net asset value per share.

     Asset-Backed Securities. The Balanced and Global Asset Portfolios may
     -----------------------                                              
purchase asset backed securities, which are securities backed by mortgages,
installment contracts, credit card receivables or other assets.  Asset-backed
securities represent interests in "pools" of assets in which payments of both
interest and principal on the securities are made monthly, thus in effect
"passing through" monthly payments made by the individual borrowers on the
assets that underlie the securities, net of any fees paid to the issuer or
guarantor of the securities.  The average life of asset-backed securities varies
with the maturities of the underlying instruments, and the average life of a
mortgage-backed instrument, in particular, is likely to be substantially less
than the original maturity of the mortgage pools underlying the securities as a
result of mortgage prepayments.  For this and other reasons, an asset-backed
security's stated maturity may be shortened, and the security's total return may
be difficult to predict precisely.  Asset-backed securities acquired by the
Portfolios may include collateralized mortgage obligations ("CMOs") issued by
private companies.

     There are a number of important differences among the agencies and
instrumentalities of the U.S.  Government that issue mortgage-related securities
and among the securities that they issue.  Mortgage-related securities
guaranteed by the Government National Mortgage Association ("GNMA") include GNMA
Mortgage Pass-Through Certificates (also known as "Ginnie Maes") which are
guaranteed as to the timely payment of principal and interest by GNMA and such
guarantee is backed by the full faith and credit of the United States.  GNMA is
a wholly-owned U.S. Government corporation within the Department of Housing and
Urban Development.  GNMA certificates also are supported by the authority of
GNMA to borrow funds from the U.S. Treasury to make payments under its
guarantee.  Mortgage-backed securities issued by the Federal National Mortgage
Association ("FNMA") include FNMA Guaranteed Mortgage Pass-Through Certificates
(also known as "Fannie Maes") which are solely the obligations of the FNMA and
are not backed by or entitled to the full faith and credit of the United States,
but are supported by the right of the issuer to borrow from the Treasury.  FNMA
is a government-sponsored organization owned entirely by private

                                      B-9    
<PAGE>
 
stockholders.  Fannie Maes are guaranteed as to timely payment of the principal
and interest by FNMA.  Mortgage-related securities issued by the Federal Home
Loan Mortgage Corporation ("FHLMC") include FHLMC Mortgage Participation
Certificates (also known as "Freddie Macs" or "PCs").  FHLMC is a corporate
instrumentality of the United States, created pursuant to an Act of Congress,
which is owned entirely by Federal Home Loan Banks.  Freddie Macs are not
guaranteed by the United States or by any Federal Home Loan Banks and do not
constitute a debt or obligation of the United States or of any Federal Home Loan
Bank.  Freddie Macs entitle the holder to timely payment of interest, which is
guaranteed by the FHLMC.  FHLMC guarantees either ultimate collection or timely
payment of all principal payments on the underlying mortgage loans.  When FHLMC
does not guarantee timely payment of principal, FHLMC may remit the amount due
on account of its guarantee of ultimate payment of principal at any time after
default on an underlying mortgage, but in no event later than one year after it
becomes payable.

     Non-mortgage asset-backed securities involve certain risks that are not
presented by mortgage-backed securities.  Primarily, these securities do not
have the benefit of the same security interest in the underlying collateral.
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 have given debtors the right to set off certain amounts owed on the credit
cards, thereby reducing the balance due.  Most issuers of automobile receivables
permit the 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
related automobile receivables.  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 an
effective security interest in all of the obligations backing such receivables.
Therefore, there is a possibility that recoveries on repossessed collateral may
not, in some cases, be able to support payments on these securities.

     Interest Rate Swaps, Floors and Caps and Currency Swaps.  The Balanced and
     -------------------------------------------------------                   
Global Asset Portfolio may enter into interest rate swaps for hedging purposes
and not for speculation.  Interest rate swaps, floors and swaps involve the
exchange by the Portfolio with another party of their respective commitments to
pay or receive interest, such as an exchange of fixed rate payments for floating
rate payments.  A Portfolio will typically use interest rate swaps to preserve a
return on a particular investment or portion of its portfolio or to shorten the
effective duration of its portfolio investments.  The purchase of an interest
rate floor or cap entitles the purchaser to receive payments of interest on a
notional principal amount from the seller, to the extent the

                                     B-10    
<PAGE>
 
specified index falls below (floor) or exceeds (cap) a predetermined interest
rate. The Portfolio will only enter into interest rate swaps or interest rate
floor or cap transactions on a net basis, i.e. the two payment streams are
netted out, with the Portfolio receiving or paying, as the case may be, only the
net amount of the two payments.

     The International Equity Index and International Growth Portfolios may
enter into currency swaps, which involve the exchange of the rights of a
Portfolio and another party to make or receive payments in specified currencies.
Currency swaps usually involve the delivery of the entire principal value of one
designated currency in exchange for the other designated currency.

    
     Inasmuch as interest rate and currency swaps are entered into for good
faith hedging purposes, the Trust, The Northern Trust Company ("Northern") and
Northern Trust Quantitative Advisors, Inc. ("NTQA" and, collectively with
Northern, the "Investment Advisers") believe that such transactions do not
constitute senior securities as defined in the 1940 Act and, accordingly, will
not treat them as being subject to the Portfolios' borrowing restrictions. The
net amount of the excess, if any, of a Portfolio's obligations over its
entitlements with respect to interest rate or currency swaps will be accrued on
a daily basis and an amount of liquid assets having an aggregate net asset value
at least equal to such accrued excess will be segregated by the Portfolio.     

    
     The Balanced and Global Asset Portfolios will not enter into an interest
rate swap, floor or cap transaction, and the International Equity Index,
International Growth and Global Asset Portfolios will not enter into currency
swap transactions unless the unsecured commercial paper, senior debt or the
claims-paying ability of the other party thereto is rated either A or A-l or
better by S&P, Duff or Fitch, or A or P-1 or better by Moody's.  If there is a
default by the other party to such transaction, the Portfolios 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 markets for other similar instruments which
are traded in the interbank market.     

     Futures Contracts and Related Options.  Each Portfolio may invest in
     -------------------------------------                               
futures contracts and may purchase and sell call and put options on futures
contracts for hedging purposes, for speculative purposes (to seek to increase
total return),  or for liquidity management purposes. For a detailed description
of futures contracts and related options, see Appendix B to this Additional
Statement.

     Real Estate Investment Trusts.  The Small Company Index Portfolio may
     -----------------------------                                        
invest in equity real estate investment trusts ("REITs") that constitute a part
of the Russell 2000 Small Stock Index.  REITs pool investors' funds for
investment primarily in commercial real estate properties.  Investments in REITs
may subject the Portfolio to certain risks.  REITs may be affected by changes in
the value of the underlying property owned by the trust.  REITs are dependent
upon specialized management skill, may not be diversified and are subject to the
risks of financing projects.  REITs are also subject to heavy cash flow
dependency, defaults by borrowers, self liquidation and the possibility of
failing to qualify for the beneficial tax treatment available to REITs under the
Internal Revenue Code of 1986, as amended, and to maintain exemption from the
1940 Act.  As a shareholder in a REIT, the Portfolio would bear, along with
other shareholders, its pro rata portion of the REIT's operating expenses.
These expenses would be in addition to the advisory and other expenses the
Portfolio bears directly in connection with its own operations.

     Securities Lending.  Collateral for loans of portfolio securities made by a
     ------------------                                                         
Portfolio may consist of cash, securities issued or guaranteed by the U.S.
Government or its agencies or irrevocable bank letters of credit (or any
combination thereof). The borrower of securities will be required to maintain
the market value of the collateral at not less than the market value of the
loaned securities, and such value will be monitored on a daily basis.  When a
Portfolio lends its securities, it continues to receive dividends and interest
on the securities loaned and may simultaneously earn interest on the investment
of the cash collateral.  Although voting rights, or rights to consent, attendant
to securities on loan pass to the borrower, such loans will be called so that
the securities may be voted by a Portfolio if a material event affecting the
investment is to occur.

    
     Forward Commitments, When-Issued Securities and Delayed Delivery
     ----------------------------------------------------------------
Transactions.  When a Portfolio purchases securities on a when-issued, delayed
- ------------                                                                  
delivery or forward commitment basis, the Portfolio will segregate liquid assets
having a value (determined daily) at least equal to the amount of the
Portfolio's purchase commitments.  In the case of a forward commitment to sell
portfolio securities, the Portfolio will segregate the portfolio securities
themselves.  These procedures are designed to ensure that the Portfolio will
maintain sufficient assets at all times to cover its obligations under when-
issued purchases, forward commitments and delayed delivery transactions.     

     Commercial Paper, Bankers' Acceptances, Certificates of Deposit, Time
     ---------------------------------------------------------------------
Deposits and Bank Notes.  Commercial paper represents short-term unsecured
- -----------------------                                                   
promissory notes issued in bearer form by banks or bank holding companies,
corporations and finance companies.  Certificates of deposit are negotiable
certificates issued against funds deposited in a commercial bank for a definite

                                     B-12    
<PAGE>
 
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 that 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.  Bank notes rank junior to deposit liabilities of banks and pari passu
                                                                   ---- -----
with other senior, unsecured obligations of the bank. Bank notes are classified
as "other borrowings" on a bank's balance sheet, while deposit notes and
certificates of deposit are classified as deposits.  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.

     Each Portfolio may invest a portion of its assets in the obligations of
foreign banks and foreign branches of domestic banks.  Such obligations include
Eurodollar Certificates of Deposit ("ECDs") which are U.S. dollar-denominated
certificates of deposit issued by offices of foreign and domestic banks located
outside the United States; Eurodollar Time Deposits ("ETDs") which are U.S.
dollar-denominated deposits in a foreign branch of a U.S. bank or a foreign
bank; Canadian Time Deposits ("CTDs") which are essentially the same as ETDs
except they are issued by Canadian offices of major Canadian banks; Schedule Bs,
which are obligations issued by Canadian branches of foreign or domestic banks;
Yankee Certificates of Deposit ("Yankee CDs") which are U.S. dollar-denominated
certificates of deposit issued by a U.S. branch of a foreign bank and held in
the United States; and Yankee Bankers' Acceptances ("Yankee BAs") which are U.S.
dollar-denominated bankers' acceptances issued by a U.S. branch of a foreign
bank and held in the United States.

     Variable and Floating Rate Instruments.  With respect to the variable and
     --------------------------------------                                   
floating rate instruments that may be acquired by the Portfolios, the Investment
Advisers will consider the earning power, cash flows and other liquidity ratios
of the issuers and guarantors of such instruments and, if the instruments are
subject to demand features, will continuously monitor their financial status and
ability to meet payment on demand.  Where necessary to ensure that a variable or
floating rate instrument meets the Portfolios' quality requirements, the
issuer's obligation to pay the principal of the instrument will be backed by an
unconditional bank letter or line of credit, guarantee or commitment to lend.

     Repurchase Agreements.  Each Portfolio may enter into repurchase agreements
     ---------------------                                                      
with financial institutions, such as banks and broker-dealers, as are deemed
creditworthy by the Investment Advisers under guidelines approved by the Trust's
Board of Trustees.  The repurchase price under the repurchase agreements will
generally equal the price paid by a Portfolio plus interest negotiated on the
basis of current short-term rates (which may be more or less than the rate on
the securities underlying the repurchase agreement).  Securities subject to
repurchase agreements will be held by the Trust's custodian (or subcustodian),
in the Federal Reserve/Treasury book-entry system or by another authorized
securities depository.  Repurchase agreements are considered to be loans by a
Portfolio under the 1940 Act.

     Reverse Repurchase Agreements.  Each Portfolio may borrow funds for
     -----------------------------                                      
temporary or emergency purposes by selling portfolio securities to financial
institutions such as banks and broker/dealers and agreeing to repurchase them at
a mutually specified date and price ("reverse repurchase agreements").  Reverse
repurchase agreements involve the risk that the market value of the securities
sold by a Portfolio may decline below the repurchase price.  The Portfolio will
pay interest on amounts obtained pursuant to a reverse repurchase agreement.
While reverse repurchase agreements are outstanding, a Portfolio will segregate
liquid assets in an amount at least equal to the market value of the securities,
plus accrued interest, subject to the agreement.  Reverse repurchase agreements
are considered to be borrowings by a Portfolio under the 1940 Act.

     Investment Companies.
     -------------------- 

    
     The 1940 Act generally permits the Global Asset Portfolio to invest without
limitation in other investment companies that are part of the same "group of
investment companies" (as defined in the 1940 Act), provided certain limitations
are observed.  Generally, these limitations require that the Portfolio (a) limit
its investments to shares of other investment companies that are part of the
same "group of investment companies," Government securities and short-term
paper, (b) observe certain limitations on the amount of sales loads and
distribution-related fees that are borne directly and indirectly by its
shareholders; and (c) not invest in other investment companies structured as
"funds of funds."  If the SEC grants the order of exemption that has been
requested by the Trust, (a) the Global Asset Portfolio will be permitted to hold
investments other than those identified above, including domestic and foreign
equity and fixed income securities and securities of unaffiliated investment
companies; and (b) the Portfolios will be permitted to invest in the securities
of unaffiliated investment companies as described below.     

    
     With respect to (i) the investments of the Global Asset Portfolio in
securities issued by all unaffiliated investment     

                                     B-14    
<PAGE>
 
    
companies, (ii) the investments of other Portfolios in which the Global Asset
Portfolio invests in (a) unaffiliated money market funds and (b) other
unaffiliated investment companies issuing shares which are traded like
traditional equity securities on a national stock exchange or the NASDAQ
National Market System ("Exchange-Traded Funds") and (iii) the investments of
other Portfolios in which the Global Asset Portfolio does not invest in the
securities of all unaffiliated investment companies, such investments will be
limited so that, as determined after a purchase is made, either (x) not more
than 3% of the total outstanding stock of such investment company will be owned
by the Portfolio, the Trust as a whole and their affiliated persons (as defined
in the 1940 Act) or (y) the percentage limitations in the next sentence are
satisfied.  In all cases, each Portfolio in which the Global Asset Portfolio
invests will limit its investments in other types of investment companies not
listed in (ii) above so that, as determined after a purchase is made, (i) not
more than 5% of the value of its total assets will be invested in the securities
of any one investment company; (ii) not more than 10% of the value of its total
assets will be invested in the aggregate in securities of investment companies
as a group (not including investments in money market funds and Exchange-Traded
Funds); and (iii) not more than 3% of the outstanding voting stock of any one
investment company will be owned by the Portfolio.  In addition, each Portfolio
in which the Global Asset Portfolio invests will limit its investments in
unaffiliated money market funds so that no more than 25% of such Portfolio's
assets are invested in such money market funds.     

    
     Certain investment companies, i.e., unaffiliated investment companies whose
securities are purchased by the Portfolios, may not be obligated to redeem such
securities in an amount exceeding 1% of their total outstanding securities
during any period of less than 30 days.  Therefore, such securities that exceed
this amount may be illiquid.     

    
     If required by the 1940 Act, each Portfolio expects to vote the shares of
other investment companies that are held by it in the same proportion as the
vote of all other holders of such securities.     

    
     A Portfolio may invest all or substantially all of its assets in a single
open-end investment company or series thereof with substantially the same
investment objective, policy and restrictions as the Portfolio.  However, each
Portfolio currently intends to limit its investments in securities issued by
other investment companies to the extent described above.  A Portfolio may
adhere to more restrictive limitations with respect to its investments in
securities issued by other investment companies if required by the SEC or deemed
to be in the best interests of the Trust.

World Equity Benchmark Shares ("WEBS")     
- --------------------------------------

    
As outlined in the Prospectus, the International Equity Index and Global Asset
Portfolios may invest in WEBS and similar securities of investment companies
that invest in securities included in foreign securities indices.  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 listing of WEBS will continue
to be met or will remain unchanged.  In the event substantial market or other
disruptions affecting WEBS should occur in the future, the liquidity and value
of a Portfolio's shares could also be substantially and adversely affected, and
the International Equity Index Portfolio's ability to provide investment results
approximating the performance of securities in the EAFE Index could be impaired.
If such disruptions were to occur, the Portfolio could be required to reconsider
the use of WEBS as part of its investment strategy.     

     Risks Related to Lower-Rated Securities.  While any investment carries some
     ---------------------------------------                                    
risk, certain risks associated with lower-rated securities are different than
those for investment-grade securities.  The risk of loss through default is
greater because lower-rated securities are usually unsecured and are often
subordinate to an issuer's other obligations.  Additionally, the issuers of
these securities frequently have high debt levels and are thus more sensitive to
difficult economic conditions, individual corporate developments and rising
interest rates.  Consequently, the market price of these securities may be quite
volatile and may result in wider fluctuations of a Portfolio's net asset value
per share.

     There remains some uncertainty about the performance level of the market
for lower-rated securities under adverse market and economic environments.  An
economic downturn or increase in interest rates could have a negative impact on
both the market for lower-rated securities (resulting in a greater number of
bond defaults) and the value of lower-rated securities held in the portfolio of
investments.

     The economy and interest rates can affect lower-rated securities
differently than other securities.  For example, the prices of lower-rated
securities are more sensitive to adverse economic changes or individual
corporate developments than are the prices of higher-rated investments.  In
addition, during an

                                     B-16    
<PAGE>
 
economic downturn or period in which interest rates are rising significantly,
highly leveraged issuers may experience financial difficulties, which, in turn,
would adversely affect their ability to service their principal and interest
payment obligations, meet projected business goals and obtain additional
financing.

     If an issuer of a security defaults, a Portfolio may incur additional
expenses to seek recovery.  In addition, periods of economic uncertainty would
likely result in increased volatility for the market prices of lower-rated
securities as well as a Portfolio's net asset value.  In general, both the
prices and yields of lower-rated securities will fluctuate.

     In certain circumstances it may be difficult to determine a security's fair
value due to a lack of reliable objective information.  Such instances occur
where there is not an established secondary market for the security or the
security is lightly traded.  As a result, a Portfolio's valuation of a security
and the price it is actually able to obtain when it sells the security could
differ.

     Adverse publicity and investor perceptions, whether or not based on
fundamental analysis, may decrease the value and liquidity of lower-rated
securities held by a Portfolio, especially in a thinly traded market.  Illiquid
or restricted securities held by the Portfolio may involve special registration
responsibilities, liabilities and costs, and could involve other liquidity and
valuation difficulties.

    
     The ratings of S&P, Moody's, Duff and Fitch evaluate the safety of a lower-
rated security's principal and interest payments, but do not address market
value risk.  Because the ratings of the rating agencies may not always reflect
current conditions and events, in addition to using recognized rating agencies
and other sources, the Investment Advisers perform their own analysis of the
issuers whose lower-rated securities the Portfolio purchases.  Because of this,
the Portfolio's performance may depend more on their own credit analysis than is
the case of mutual funds investing in higher-rated securities.     

     In selecting lower-rated securities, the Investment Advisers consider
factors such as those relating to the creditworthiness of issuers, the ratings
and performance of the securities, the protections afforded the securities and
the diversity of a Portfolio's investment portfolio.  The Investment Advisers
continuously monitor the issuers of lower-rated securities held by a Portfolio
for their ability to make required principal and interest payments, as well as
in an effort to control the liquidity of the Portfolio so that it can meet
redemption requests.

          Yields and Ratings.  The yields on certain obligations, including the
          ------------------                                                   
instruments in which the Portfolios may invest, are

                                     B-17    
<PAGE>
 
dependent on a variety of factors, including general market conditions,
conditions in the particular market for the obligation, financial condition of
the issuer, size of the offering, maturity of the obligation and ratings of the
issue.  The ratings of S&P, Moody's, Duff, Fitch and TBW represent their
respective opinions as to the quality of the obligations they undertake to rate.
Ratings, however, are general and are not absolute standards of quality.
Consequently, obligations with the same rating, maturity and interest rate may
have different market prices.

     Subject to the limitations stated in the Prospectus, if a portfolio
security undergoes a rating revision, a Portfolio may continue to hold the
security if the Investment Advisers determine such retention is warranted.

     Calculation of Portfolio Turnover Rate.  The portfolio turnover rate for
     --------------------------------------                                  
the Portfolios is calculated by dividing the lesser of purchases or sales of
portfolio investments for the reporting period by the monthly average value of
the portfolio investments owned during the reporting period.  The calculation
excludes all securities, including options, whose maturities or expiration dates
at the time of acquisition are one year or less. Portfolio turnover may vary
greatly from year to year as well as within a particular year, and may be
affected by cash requirements for redemption of shares and by requirements which
enable the Portfolios to receive favorable tax treatment.

INVESTMENT RESTRICTIONS

     In addition to the fundamental investment restrictions disclosed in the
Prospectus, each Portfolio is subject to the fundamental investment restrictions
enumerated below which may be changed with respect to a particular Portfolio
only by a vote of the holders of a majority of such Portfolio's outstanding
shares.

No Portfolio may:

     (1) Make loans, except (a) through the purchase of debt obligations in
     accordance with the Portfolio's investment objective and policies, (b)
     through repurchase agreements with banks, brokers, dealers and other
     financial institutions, and (c) loans of securities.

     (2) Mortgage, pledge or hypothecate any assets (other than pursuant to
     reverse repurchase agreements) except to secure permitted borrowings.

     (3) Purchase or sell real estate, but this restriction shall not prevent a
     Portfolio from investing directly or indirectly in portfolio instruments
     secured by real estate or interests therein or acquiring securities of real
     estate investment trusts or other issuers that deal in real estate.

                                     B-18    
<PAGE>
 
     (4) Purchase or sell commodities or commodity contracts or oil or gas or
     other mineral exploration or development programs, except that each
     Portfolio may, to the extent appropriate to its investment policies,
     purchase securities of companies engaging in whole or in part in such
     activities, enter into futures contracts and related options, and enter
     into forward currency contracts in accordance with its investment objective
     and policies.

     (5) Invest in companies for the purpose of exercising control.

    
     (6) Act as underwriter of securities, except as a Portfolio may be deemed
     to be an underwriter under the Securities Act of 1933 in connection with
     the purchase and sale of portfolio instruments in accordance with its
     investment objective and portfolio management policies.     

     (7) Write puts, calls or combinations thereof, except for transactions in
     options on securities, financial instruments, currencies and indices of
     securities (and in the case of the International Growth Portfolio, yield
     curve options); futures contracts; options on futures contracts; forward
     currency contracts; short sales of securities against the box; interest
     rate swaps; and pair-off transactions (except in the case of the
     International Growth Portfolio).

    
     (8) Make any investment inconsistent with the Portfolio's classification as
     a diversified investment company under the 1940 Act.     

     (9) Purchase securities (other than obligations issued or guaranteed by the
     U.S. Government, its agencies or instrumentalities and, in the case of the
     International Equity Index and Global Asset Portfolios, securities of other
     investment companies) if such purchase would cause more than 25% in the
     aggregate of the market value of the total assets of a Portfolio to be
     invested in the securities of one or more issuers having their principal
     business activities in the same industry. For the purposes of this
     restriction, as to utility companies, the gas, electric, water and
     telephone businesses are considered separate industries; 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 industries of their parents if their activities are primarily
     related to financing the activities of their parents.

     (10) Borrow money (other than pursuant to reverse repurchase agreements),
     except (a) as a temporary measure, and then only in amounts not exceeding
     5% of the value of the Portfolio's total assets or (b) from banks, provided
     that immediately

                                     B-19    
<PAGE>
 
     after any such borrowing all borrowings of the Portfolio do not exceed one-
     third of the Portfolio's total assets.  No purchases of securities will be
     made if borrowings subject to this restriction exceed 5% of the value of
     the Portfolio's assets.  The exceptions in (a) and (b) to this restriction
     are not for investment leverage purposes but are solely for extraordinary
     or emergency purposes or to facilitate management of the Portfolios by
     enabling the Trust to meet redemption requests when the liquidation of
     Portfolio instruments is deemed to be disadvantageous or not possible.  If
     due to market fluctuations or other reasons the total assets of a Portfolio
     fall below 300% of its borrowings, the Trust will promptly reduce the
     borrowings of such Portfolio in accordance with the 1940 Act.

     (11) Notwithstanding any of the Trust's other fundamental investment
     restrictions (including, without limitation, those restrictions relating to
     issuer diversification, industry concentration and control), each Portfolio
     may purchase securities of other investment companies to the full extent
     permitted under Section 12 of the 1940 Act (or any successor provision
     thereto) or under any regulation or order of the Securities and Exchange
     Commission; and each Portfolio may invest all or substantially all of its
     assets in a single open-end investment company or series thereof with
     substantially the same investment objective, policies and fundamental
     restrictions as the Portfolio.

                        *     *     *

     In applying Restriction No. 9 above, a security is considered to be issued
by the entity, or entities, whose assets and revenues back the security.  A
guarantee of a security is not deemed to be a security issued by the guarantor
when the value of all securities issued and guaranteed by the guarantor, and
owned by a Portfolio, does not exceed 10% of the value of the Portfolio's total
assets.

    
     Except to the extent otherwise provided in Investment Restriction No. 9 for
the purpose of such restriction, in determining industry classification the
Trust intends to use the industry classification titles in the Standard
Industrial Classification Manual (except that the International Growth Portfolio
and the International Equity Index Portfolio will use The Morgan Stanley Capital
International industry classification titles).  Securities held in escrow or
separate accounts in connection with a Portfolio's investment practices
described in this Additional Statement and in the Prospectus are not deemed to
be mortgaged, pledged or hypothecated for purposes of the foregoing Investment
Restrictions.     

     In addition, as a matter of fundamental policy, the International Equity
Index and International Growth Portfolios will

                                     B-20    
<PAGE>
 
not issue senior securities except as stated in the Prospectus or this
Additional Statement.

     Any restriction which involves a maximum percentage will 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.

Certain of the Trustees and officers and the organizations with which they are
associated have had in the past, and may have in the future, transactions with
the Investment Advisers, Goldman Sachs and their respective affiliates.  The
Trust has been advised by such Trustees and officers that all such transactions
have been and are expected to be in the ordinary course of business and the
terms of such transactions, including all loans and loan commitments by such
persons, have been and are expected to be substantially the same as the
prevailing terms for comparable transactions for other customers.  Messrs.
Springer, Kelsey, Strubel, Mosior, Gilman, Richman, Surloff and Hartstein and
Mmes. Farrell, Mucker and Zondorak hold similar positions with one or more
investment companies that are advised by Goldman Sachs.  As a result of the
responsibilities assumed by the Investment Advisers under the Advisory Agreement
with the Trust, by Northern under its Transfer Agency Agreement, Custodian
Agreement and Foreign Custody Agreement with the Trust and by Goldman Sachs
under its Administration Agreement and Distribution Agreement with the Trust,
the Trust itself requires no employees.

Each officer holds comparable positions with certain other investment companies
of which Goldman Sachs, GSAM or an affiliate thereof is the investment adviser,
administrator and/or distributor.

Each Trustee earns a quarterly retainer of $6,250 and the Chairman of the Board
earns a quarterly retainer of $9,375.  Each Trustee, including the Chairman of
the Board, earns an additional fee of $1,500 for each meeting attended, plus
reimbursement of expenses incurred as a Trustee.

In addition, the Trustees established an Audit Committee consisting of three
members including a Chairman of the Committee.  Each member earns a fee of
$1,500 for each meeting attended and the Chairman earns a quarterly retainer of
$1,250.

Each Trustee will hold office for an indefinite term until the earliest of (1)
the next meeting of shareholders if any, called for the purpose of considering
the election or re-election of such Trustee and until the election and
qualification of his or her successor, if any, elected at such meeting; (2) the
date a Trustee resigns or retires, or a Trustee is removed by the Board of
Trustees or shareholders, in accordance with the Trust's Agreement and
Declaration of Trust, or (3) in accordance with the current resolutions of the
Board of Trustees (which may be changed without shareholder vote), on the last
day of the fiscal year of the Trust in which he or she attains the age of 72
years.

The Trust's officers do not receive fees from the Trust for services in such
capacities, although Goldman Sachs, of which they are also officers, receives
fees from the Trust for administrative services.

INVESTMENT ADVISERS, TRANSFER AGENT AND CUSTODIAN

     Northern, a wholly-owned subsidiary of Northern Trust Corporation, a bank
holding company, is one of the nation's leading providers of trust and
investment management services. Northern is one of the strongest banking
organizations in the United States.  Northern believes it has built its
organization by serving clients with integrity, a commitment to quality, and
personal attention.  Its stated mission with respect to all its financial
products and services is to achieve unrivaled client satisfaction.  With respect
to such clients, the Trust is designed to assist (i) defined contribution plan
sponsors and their employees by offering a range of diverse investment options
to help comply with 404(c) regulation and may also provide educational material
to their employees, (ii) employers who provide post-retirement Employees'
Beneficiary Associations ("VEBA") and require investments that respond to the
impact of federal regulations, (iii) insurance companies with the day-to-day
management of uninvested cash balances as well as with

                                     B-28

longer-term investment needs, and (iv) charitable and not-for-profit
organizations, such as endowments and foundations, demanding investment
management solutions that balance the requirement for sufficient current income
to meet operating expenses and the need for capital appreciation to meet future
investment objectives.  NTQA, also a wholly-owned subsidiary of Northern Trust
Corporation, serves as investment adviser principally to defined benefit and
defined contribution plans and manages over 60 equity and bond commingled and
common trust funds. As of December 31, 1997, the Investment Advisers and their
affiliates had approximately $196 billion in assets under management for clients
including public and private retirement funds, endowments, foundations, trusts,
corporations, other investment companies and individuals.     

     Subject to the general supervision of the Board of Trustees, the Investment
Advisers make the decisions with respect to and places orders for all purchases
and sales of portfolio securities for the Portfolios.  The Advisory Agreements
with the Trust provide that in selecting brokers or dealers to place orders for
transactions (a) on common and preferred stocks, the Investment Advisers shall
use their best judgment to obtain the best overall terms available, and (b) on
bonds and other fixed income obligations, the Investment Advisers shall attempt
to obtain best net price and execution. In assessing the best overall terms
available for any transaction, the Investment Advisers are to consider all
factors they deem relevant, including the breadth of the market in the security,
the price of the security, the financial condition and execution capability of
the broker or dealer, and the reasonableness of the commission, if any, both for
the specific transaction and on a continuing basis.  In evaluating the best
overall terms available and in selecting the broker or dealer to execute a
particular transaction, the Investment Advisers may consider the brokerage and
research services provided to the Portfolios and/or other accounts over which
the Investment Advisers or an affiliate of Northern exercise investment
discretion.  These brokerage and research services may include industry and
company analyses, portfolio services, quantitative data, market information
systems and economic and political consulting and analytical services.

     Transactions on U.S.  stock exchanges involve the payment of negotiated
brokerage commissions.  On exchanges on which commissions are negotiated, the
cost of transactions may vary among different brokers.  Transactions on foreign
stock exchanges involve payment for brokerage commissions which are generally
fixed.  Over-the-counter issues, including corporate debt and government
securities, are normally traded on a "net" basis (i.e., without commission)
through dealers, or otherwise involve transactions directly with the issuer of
an instrument.  With respect to over-the-counter transactions, the Investment
Advisers will normally deal directly with dealers who make a market in the
instruments involved except in those circumstances where more favorable prices

                                     B-29    
<PAGE>
 
and execution are available elsewhere.  The cost of foreign and domestic
securities purchased from underwriters includes an underwriting commission or
concession, and the prices at which securities are purchased from and sold to
dealers include a dealer's mark-up or mark-down.

     The Portfolios may participate, if and when practicable, in bidding for the
purchase of portfolio securities directly from an issuer in order to take
advantage of the lower purchase price available to members of a bidding group.
The Portfolios will engage in this practice, however, only when the Investment
Advisers believe such practice to be in the Portfolios' interests.

     On occasions when the Investment Advisers deem the purchase or sale of a
security to be in the best interests of a Portfolio as well as other fiduciary
or agency accounts managed by them (including any other Portfolio, investment
company or account for which the Investment Advisers act as adviser), the
Agreements provide that the Investment Advisers, to the extent permitted by
applicable laws and regulations, may aggregate the securities to be sold or
purchased for such Portfolio with those to be sold or purchased for such other
accounts in order to obtain best overall terms available with respect to common
and preferred stock, and best net price and execution with respect to bonds and
other fixed income obligations.  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 Investment Advisers in the manner they consider to be most equitable
and consistent with their fiduciary obligations to the Portfolio and other
accounts involved.  In some instances, this procedure may adversely affect the
size of the position obtainable for a Portfolio or the amount of the securities
that are able to be sold for a Portfolio.  To the extent that the execution and
price available from more than one broker or dealer are believed to be
comparable, the Agreements permit the Investment Advisers, at their discretion
but subject to applicable law, to select the executing broker or dealer on the
basis of their opinion of the reliability and quality of such broker or dealer.

     The Advisory Agreements provide that the Investment Advisers may render
similar services to others so long as its services under such Agreements are not
impaired thereby.  The Advisory Agreements also provide that the Trust will
indemnify the Investment Advisers against certain liabilities (including
liabilities under the Federal securities laws relating to untrue statements or
omissions of material fact and actions that are in accordance with the terms of
the Agreement) or, in lieu thereof, contribute to resulting losses.

    
     At a meeting held on September 2, 1997, shareholders of the International
Growth Portfolio approved a new advisory agreement with Northern and another
wholly-owned subsidiary of Northern Trust Corporation (The Northern Trust
Company of Connecticut, which has     

                                     B-30    
<PAGE>
 
    
principal offices at 300 Atlantic Street, Stamford, Connecticut 06901) that
would permit the Portfolio to implement a "manager-of-managers" structure.  This
agreement will become effective only if the Securities and Exchange Commission
grants an exemption that permits the Portfolio to implement a manager-of-
managers structure, and the Board of Trustees of the Trust acts to effectuate
the structure with respect to the Portfolio.  The new advisory agreement would
be identical in all material respects to the current Advisory Agreement for the
International Growth Portfolio, except that the new agreement would appoint both
Northern and The Northern Trust Company of Connecticut as the advisers of the
Portfolio and would allow the advisers to (1) delegate their duties to sub-
advisers, (2) implement a manager-of-managers structure and (3) enter into sub-
advisory agreements in the future without further shareholder approval.  Fees
payable to the sub-advisers would be payable by Northern and The Northern Trust
Company of Connecticut and not by the Portfolio, and the current investment
advisory fee rate payable by the Portfolio would not change.  At present, it is
uncertain when, or if, the manager-of-managers structure will become 
effective.     

     Under its Transfer Agency Agreement with the Trust, with respect to shares
held by Institutions, Northern has undertaken to perform some or all of the
following services: (1) establish and maintain an omnibus account in the name of
each Institution; (2) process purchase orders and redemption requests from an
Institution, furnish confirmations and disburse redemption proceeds; (3) act as
the income disbursing agent of the Trust; (4) answer inquiries from
Institutions; (5) provide periodic statements of account to each Institution;
(6) process and record the issuance and redemption of shares in accordance with
instructions from the Trust or its administrator; (7) if required by law,
prepare and forward to Institutions shareholder communications (such as proxy
statements and proxies, annual and semi-annual financial statements, and
dividend, distribution and tax notices); (8) preserve all records; and (9)
furnish necessary office space, facilities and personnel.  Under the Transfer
Agency Agreement, with respect to shares held by investors, Northern has also
undertaken to perform some or all of the following services: (1) establish and
maintain separate accounts in the name of the investors; (2) process purchase
orders and redemption requests, and furnish confirmations in accordance with
applicable law; (3) disburse redemption proceeds; (4) process and record the
issuance and redemption of shares in accordance with instructions from the Trust
or its administrator; (5) act as income disbursing agent of the Trust in
accordance with the terms of the Prospectus and instructions from the Trust or
its administrator; (6) provide periodic statements of account; (7) answer
inquiries (including requests for prospectuses and statements of additional
information, and assistance in the completion of new account applications) from
investors and respond to all requests for information regarding the Trust (such
as current price, recent performance, and yield data)

                                     B-31    
<PAGE>
 
    
and questions relating to accounts of investors (such as possible errors in
statements, and transactions); (8) respond to and seek to resolve all complaints
of investors with respect to the Trust or their accounts; (9) furnish proxy
statements and proxies, annual and semi-annual financial statements, and
dividend, distribution and tax notices to investors; (10) furnish the Trust all
pertinent Blue Sky information; (11) perform all required tax withholding; (12)
preserve records; and (13) furnish necessary office space, facilities and
personnel.  Northern may appoint one or more sub-transfer agents in the
performance of its services.     

     As compensation for the services rendered by Northern under the Transfer
Agency Agreement and the assumption by Northern of related expenses, Northern is
entitled to a fee from the Trust, payable monthly, at an annual rate of .01%,
 .05%, .10% and .15% of the average daily net asset value of the Class A, B, C
and D Shares, respectively, in the Portfolios.

    
     Under its Custodian Agreement (and in the case of the International Growth
Portfolio and International Equity Index Portfolio, its Foreign Custody
Agreement) with the Trust, Northern (1) holds each Portfolio's cash and
securities, (2) maintains such cash and securities in separate accounts in the
name of the Portfolio, (3) makes receipts and disbursements of funds on behalf
of the Portfolio, (4) receives, delivers and releases securities on behalf of
the Portfolio, (5) collects and receives all income, principal and other
payments in respect of the Portfolio's investments held by Northern under the
Agreement, and (6) maintains the accounting records of the Trust.  Northern may
employ one or more subcustodians, provided that Northern shall, subject to
certain monitoring responsibilities, have no more responsibility or liability to
the Trust on account of any action or omission of any subcustodian so employed
than such subcustodian has to Northern and that the responsibility or liability
of the subcustodian to Northern shall conform to the resolution of the Trustees
of the Trust authorizing the appointment of the particular subcustodian (or, in
the case of foreign securities, to the terms of any agreement entered into
between Northern and such subcustodian to which such resolution relates).  In
addition, the Trust's custodial arrangements provide, with respect to foreign
securities, that Northern shall not be:  (i) responsible for the solvency of any
subcustodian appointed by it with reasonable care; (ii) responsible for any act,
omission, default or for the solvency of any eligible foreign securities
depository; and (iii) liable for any loss, damage, cost, expense, liability or
claim resulting from nationalization, expropriation, currency restrictions, or
acts of war or terrorism or any loss where the subcustodian has otherwise
exercised reasonable care.  Northern may also appoint agents to carry out such
of the provisions of the Custodian Agreement and the Foreign Custody Agreement
as Northern may from time to time direct, provided that the appointment of an
agent shall not relieve Northern of any of its responsibilities under either
Agreement.     

                                     B-32

Northern has entered into agreements with financial institutions and
depositories located in foreign countries with respect to the custody of the
Portfolio's foreign securities.

     As compensation for the services rendered to the Trust by Northern as
custodian with respect to each Portfolio except the International Growth
Portfolio and International Equity Index Portfolio, and the assumption by
Northern of certain related expenses, Northern is entitled to payment from the
Trust as follows: (i) $18,000 annually for each Portfolio, plus (ii) 1/100th of
1% annually of each Portfolio's average daily net assets to the extent they
exceed $100 million, plus (iii) a fixed dollar fee for each trade in portfolio
securities, plus (iv) a fixed dollar fee for each time that Northern as
Custodian receives or transmits funds via wire, plus (v) reimbursement of
expenses incurred by Northern as custodian for telephone, postage, courier fees,
office supplies and duplicating.  The fees referred to in clauses (iii) and (iv)
are subject to annual upward adjustments based on increases in the Consumer
Price Index for All Urban Consumers, provided that Northern may permanently or
temporarily waive all or any portion of any upward adjustment.

     As compensation for the services rendered to the Trust under the Foreign
Custody Agreement with respect to the International Growth Portfolio and
International Equity Index Portfolio, and the assumption by Northern of certain
related expenses, Northern is entitled to payment from the Trust as follows:
(i) $35,000 annually for the International Growth Portfolio and International
Equity Index Portfolio, plus (ii) 9/100th of 1% annually of the Portfolios'
average daily net assets, plus (iii) reimbursement for fees incurred by Northern
as foreign custodian for telephone, postage, courier fees, office supplies and
duplicating.

    
     Northern's fee under the Custodian Agreement and Foreign Custody Agreement
are subject to reduction based on the Portfolios' daily uninvested cash balances
(if any).     

    
     Unless sooner terminated, the Advisory Agreements, the Custodian Agreement
(or in the case of the International Growth Portfolio and International Equity
Index Portfolio, the Foreign Custody Agreement) and the Transfer Agency
Agreement will continue in effect with respect to a particular Portfolio until
April 30, 1999 and thereafter for successive 12-month periods, provided that the
continuance is approved at least annually (1) by the vote of a majority of the
Trustees who are not parties to the agreement or "interested persons" (as such
term is defined in the 1940 Act) of any party thereto, cast in person at a
meeting called for the purpose of voting on such approval, and (2) by the
Trustees or by the vote of a majority of the outstanding shares of such
Portfolio (as defined below under "Other Information"). Each agreement is
terminable at any time without penalty by the Trust (by specified Trustee or
shareholder action) on 60 days' written notice to     

                                     B-33

Northern or NTQA and by Northern or NTQA on 60 days' written notice to the
Trust.

    
     Prior to April 1, Northern served as investment adviser to the Equity
Index, Small Company Index and International Equity Index Portfolios on the same
terms as those described above.     

    
     For the fiscal periods ended November 30 as indicated, the amount of the
Advisory Fee incurred by each Portfolio (after fee waivers) was as follows:

     Banking laws and regulations currently prohibit a bank holding company
registered under the Federal Bank Holding Company Act of 1956 or any bank or
non-bank affiliate thereof from sponsoring, organizing, controlling or
distributing the shares of a registered open-end investment company continuously
engaged in the issuance of its shares, but such banking laws and regulations do
not prohibit such a holding company or affiliate or banks generally from acting
as investment adviser, transfer agent or custodian to such an investment
company, or from purchasing shares of such a company as agent for and upon the
order of customers.  Northern and NTQA believe that they may perform the
services contemplated by their agreements with the Trust without violation of
such banking laws or regulations, which are applicable to them.  It should be
noted, however, that future changes in either Federal or state statutes and
regulations relating to the permissible activities of banks and their
subsidiaries or affiliates, as well as future judicial or administrative
decisions or interpretations of current and future     

                                     B-35    
<PAGE>
 
    
statutes and regulations, could prevent Northern and NTQA from continuing to
perform such services for the Trust.     

    
     Should future legislative, judicial or administrative action prohibit or
restrict the activities of Northern or NTQA in connection with the provision of
services on behalf of the Trust, the Trust might be required to alter materially
or discontinue its arrangements with Northern or NTQA and change its method of
operations.  It is not anticipated, however, that any change in the Trust's
method of operations would affect the net asset value per share of any Portfolio
or result in a financial loss to any shareholder.  Moreover, if current
restrictions preventing a bank from legally sponsoring, organizing, controlling
or distributing shares of an open-end investment company were relaxed, the Trust
expects that Northern and its affiliates would consider the possibility of
offering to perform some or all of the services now provided by Goldman Sachs.
It is not possible, of course, to predict whether or in what form such
restrictions might be relaxed or the terms upon which Northern and its
affiliates might offer to provide services for consideration by the 
Trustees.     

     Goldman Sachs is also an active investor, dealer and/or underwriter in many
types of stocks, bonds and other instruments. Its activities in this regard
could have some effect on the market for those instruments which the Portfolios
acquire, hold or sell.

     In the Advisory Agreements, the Investment Advisers agree that the name
"The Benchmark" may be used in connection with the Trust's business on a
royalty-free basis.  Northern has reserved to itself the right to grant the non-
exclusive right to use the name "The Benchmark" to any other person.  The
Advisory Agreements provide that at such time as the Agreements are no longer in
effect, the Trust will cease using the name "The Benchmark." (This undertaking
by the Trust may be subject to certain legal limitations.)

PORTFOLIO TRANSACTIONS

     To the extent that a Portfolio effects brokerage transactions with Goldman
Sachs or any broker-dealer affiliated directly or indirectly with the Investment
Advisers, such transactions, including the frequency thereof, the receipt of any
commissions payable in connection therewith, and the selection of the affiliated
broker-dealer effecting such transactions, will be fair and reasonable to the
shareholders of the Portfolio.

    
     During the fiscal year ended November 30, 1997, the International Equity
Index Portfolio acquired and sold securities of Banque Paribas and Societe
Generale Securities Corporation, each a regular broker/dealer. At November 30,

ADMINISTRATOR AND DISTRIBUTOR

    
     Under its Administration Agreement with the Trust, Goldman Sachs, subject
to the general supervision of the Trust's Board of Trustees, acts as the Trust's
Administrator.  In this capacity, Goldman Sachs (1) provides supervision of
certain aspects of the Trust's non-investment advisory operations (the parties
giving due recognition to the fact that certain of such operations are performed
by Northern pursuant to the Trust's agreements with Northern), (2) provides the
Trust, to the extent not provided pursuant to such agreements, with such
personnel as are reasonably necessary for the conduct of the Trust's affairs,
(3) arranges, to the extent not provided pursuant to such agreements, for the
preparation at the Trust's expense of its tax returns, reports to shareholders,
periodic updating of the prospectuses issued by the Trust, and reports filed
with the SEC and other regulatory authorities (including qualification under
state securities or Blue Sky laws of the Trust's shares), and (4) provides the
Trust, to the extent not provided pursuant to such agreements, with adequate
office space and equipment and certain related services in Chicago.     

     For the fiscal periods ended November 30 as indicated, Goldman Sachs
received fees under the Administration Agreement (after fee waivers) in the
amount of:

     For the fiscal periods ended November 30 as indicated and prior to May 1,
1997, Goldman Sachs voluntarily agreed to waive a portion of its Administration
Fee for each Portfolio resulting in an effective fee of .10% of the average
daily net assets for each Portfolio.  The effect of these waivers by Goldman
Sachs was to reduce administration fees by the following amounts:

     In addition, pursuant to an undertaking that commenced August 1, 1992,
Goldman Sachs agreed that, if its administration fees (less expense
reimbursements paid by Goldman Sachs to the Trust and less certain marketing
expenses paid by Goldman Sachs) exceed a specified amount ($1 million for the
Trust's first twelve investment portfolios plus $50,000 for each additional
portfolio) during the current fiscal year, Goldman Sachs will waive a portion of
its administration fees during the following fiscal year.  This undertaking may
be terminated by Goldman Sachs at any time without the consent of the Trust or
the shareholders. There have been no waivers pursuant to this agreement during
the last three fiscal periods.

     Goldman Sachs has agreed for the current fiscal year to reimburse each
Portfolio for all expenses (including fees payable to Goldman Sachs as
administrator, but excluding advisory fees, transfer agency fees, servicing fees
and extraordinary expenses) which exceed on an annualized basis .25% of the
International Equity Index and International Growth Portfolios' respective
average daily net assets and .10% of each other Portfolio's average daily net
assets.  Prior to May 1, 1997, this undertaking was voluntary with respect to
the Portfolios.  As of May 1, 1997, this undertaking is contractual with respect
to all Portfolios.  The effect of these reimbursements by Goldman Sachs for the
fiscal periods ended November 30 as indicated were to reduce the expenses of
each Portfolio by:

     Unless sooner terminated, the Administration Agreement will continue in
effect with respect to a particular Portfolio until April 30, 1999, and
thereafter for successive 12-month periods, provided that the agreement is
approved annually (1) by the vote of a majority of the Trustees who are not
parties to the agreement or "interested persons" (as such term is defined by the
1940 Act) of any party thereto, cast in person at a meeting called for the
purpose of voting on such approval, and (2) by the Trustees or by the vote of a
majority of the outstanding shares of such Portfolio (as defined below under
"Other Information").  The Administration Agreement is terminable at any time
without penalty by the Trust (upon specified Trustee or shareholder action) on
60 days' written notice to Goldman Sachs and by Goldman Sachs on 60 days'
written notice to the Trust.

     The Trust has entered into a Distribution Agreement under which Goldman
Sachs, as agent, sells shares of each Portfolio on a continuous basis.  Goldman
Sachs pays the cost of printing and distributing prospectuses to persons who are
not shareholders of the Trust (excluding preparation and typesetting expenses)
and of certain other distribution efforts.  No compensation is payable by the
Trust to Goldman Sachs for such distribution services.

     The Administration Agreement and the Distribution Agreement provide that
Goldman Sachs may render similar services to others so long as its services
under such Agreements are not impaired thereby.  The Administration Agreement
provides that the Trust will indemnify Goldman Sachs against certain liabilities
(including liabilities under the Federal securities laws relating to untrue
statements or omissions of material fact and actions that are in accordance with
the terms of the Administration Agreement and Distribution Agreement) or, in
lieu thereof, contribute to resulting losses.

SHAREHOLDER SERVICING PLAN

     As stated in the Portfolios' Prospectus, Institutions may enter into
Servicing Agreements with the Trust under which they

                                     B-43    
<PAGE>
 
provide (or arrange to have provided) support services to their Customers or
other investors who beneficially own such shares in consideration of the
Portfolios' payment of not more than .10%, .15% and .25% (on an annualized
basis) of the average daily net asset value of the Class B, C and D Shares,
respectively, beneficially owned by such Customers or investors.

     For the fiscal periods ended November 30 as indicated, the aggregate amount
of the Shareholder Service Fee incurred by each class of each Portfolio then in
existence was as follows:

     The Trust's agreements with Institutions are governed by a Plan (called the
"Shareholder Servicing Plan"), which has been adopted by the Board of Trustees.
Pursuant to the Shareholder Servicing Plan, the Board of Trustees will review,
at least quarterly, a written report of the amounts expended under the Trust's
agreements with Institutions and the purposes for which the expenditures were
made.  In addition, the arrangements with Institutions must be approved annually
by a majority of the Board of Trustees, including a majority of the Trustees who
are not "interested persons" of the Trust, as defined in the 1940 Act, and have
no direct or indirect financial interest in such arrangements.

     The Board of Trustees has approved the arrangements with Institutions based
on information provided by the Trust's service contractors that there is a
reasonable likelihood that the arrangements will benefit the Portfolios and
their shareholders by affording the Portfolios greater flexibility in connection
with the servicing of the accounts of the beneficial owners of their shares in
an efficient manner.

IN-KIND PURCHASES

     Payment for shares of a Portfolio may, in the discretion of Northern, be
made in the form of securities that are permissible investments for the
Portfolio as described in the Prospectus. For further information about this
form of payment, contact Northern. In connection with an in-kind securities
payment, a Portfolio will require, among other things, that the securities be
valued on the day of purchase in accordance with the pricing methods used by the
Portfolio and that the Portfolio receive satisfactory assurances that it will
have good and marketable title to the securities received by it; that the
securities be in proper form for transfer to the Portfolio; and that adequate
information be provided concerning the basis and other tax matters relating to
the securities.

     The additional transaction fee described in the Prospectus with respect to
the Small Company Index Portfolio and the International Equity Index Portfolio
does not apply to in-kind purchases of shares that are structured to minimize
the related brokerage, market impact costs and other transaction costs to such
Portfolios as described in the Prospectus.

                            PERFORMANCE INFORMATION

     Each Portfolio that advertises an "average annual total return" for a class
of shares computes such return by determining the average annual compounded rate
of return during specified periods that equates the initial amount invested to
the ending redeemable value of such investment according to the following
formula:

                          T=(ERV)1-1
                             --- - 
                              P  N

Where:    T =  average annual total return.

          ERV =  ending redeemable value at the end of the applicable period (or
          fractional portion thereof) of a hypothetical $1,000 payment made at
          the beginning of the period.

                                     B-46    
<PAGE>
 
          P =  hypothetical initial payment of $1,000.

          n =  period covered by the computation, expressed in terms of years.

     Each Portfolio that advertises an "aggregate total return" for a class of
shares computes such return by determining the aggregate compounded rates of
return during specified periods that likewise equate the initial amount invested
to the ending redeemable value of such investment.  The formula for calculating
aggregate total return is as follows:

                          T=[(ERV)]-1
                              ---  
                               P  

    
     The calculations set forth below are made assuming that (1) all dividends
and capital gain distributions are reinvested on the reinvestment dates at the
price per share existing on the reinvestment date, (2) all recurring fees
charged to all shareholder accounts are included, and (3) the portfolio
transaction fee is taken into account for purchases of shares of the Small
Company Index Portfolio and the International Equity Index Portfolio.  The
ending redeemable value (variable "ERV" in the formula) is determined by
assuming complete redemption of the hypothetical investment after deduction of
all nonrecurring charges at the end of the measuring period.     

     The average annual total and aggregate total returns shown below for the
Diversified Growth, Equity Index, Small Company Index and International Growth
Portfolios include, for periods prior to the commencement of the Portfolios'
operations, the performance of predecessor collective funds adjusted to reflect
the higher estimated fees and expenses applicable to such Portfolios' Class A
Shares at the time of their commencement.  Although all such predecessor
collective funds were managed by Northern for the periods stated in a manner and
pursuant to investment objectives that were equivalent in all material respects
to the management and investment objectives of the corresponding Portfolios,
such predecessor collective funds were not registered under the 1940 Act and
were not subject to certain investment restrictions imposed by the 1940 Act.  If
they had been registered under the 1940 Act, performance might have been
adversely affected.  The average annual total returns and aggregate total
returns shown for the Portfolios for their Class C and/or Class D Shares also
include, for the periods prior to the inception of such classes, the performance
of the Portfolios' Class A Shares.  Because the fees and expenses of Class C and
Class D Shares are, respectively, 0.24% and 0.39% higher than those of Class A
Shares, actual performance for periods

                                     B-47    
<PAGE>
 
prior to the inception of Class C and Class D Shares would have been lower if
such higher fees and expenses had been taken into account.

    
Following commencement of operations of the Portfolios, Goldman Sachs reimbursed
expenses to the Portfolios and voluntarily agreed to reduce a portion of its
administration fee for each Portfolio pursuant to the undertaking described
above under "Additional Trust Information - Administrator and Distributor" and
"-Investment Advisers, Transfer Agent and Custodian," and Northern waived a
portion of its investment advisory fees with respect to the Portfolios. The
average annual total returns and aggregate total returns of each Portfolio with
respect to Class A, Class C and Class D Shares, as applicable, are shown below
with and without such fee waivers and expense reimbursements.

Each of the Balanced Portfolio and the Global Asset Portfolio calculates its 30-
day (or one month) standard yield as described in the Prospectus for a class of
shares in accordance with the method prescribed by the SEC for mutual funds:

                         Yield = 2[(/ / p +1)/6/1]
                                    --------
                                       nd 
**
Where:      a = dividends and interest earned during the period.

            b = expenses accrued for the period (net of reimbursements).

            c = the average daily number of shares outstanding during the period
            that were entitled to receive dividends.

            d = maximum offering price per share on the last day of the period.

    
     For the 30-day period ended November 30, 1997, the annualized yields of the
Class A, Class C and Class D Shares of the Balanced Portfolio was 2.68%, 2.44%
and 2.29%, respectively.  During such period, Goldman Sachs reimbursed expenses
to the Portfolio and voluntarily agreed to reduce a portion of its
administration fees under "Additional Trust Information - Administrator and
Distributor", and Northern waived a portion of its investment advisory fees with
respect to the Portfolio.  In the absence of such advisory and administration
fee reductions and expense limitations, the 30-day yield for Class A, Class C
and Class D Shares would have been 2.54%, 2.30% and 2.15%, respectively.     

     The performance of any investment is generally a function of portfolio
quality and maturity, type of investment and operating expenses.

     Because of the different Servicing Fees and transfer agency fees payable
with respect to Class A, B, C and D Shares in a Portfolio, performance
quotations for shares of Class B, C and D of the Portfolio will be lower than
the quotations for Class A Shares of the Portfolio, which will not bear any fees
for shareholder support services and will bear minimal transfer agency fees.

                                     TAXES

     The following summarizes certain additional tax considerations generally
affecting the Portfolios and their shareholders that are not described in the
Portfolios' Prospectus.  No attempt is made to present a detailed explanation of
the tax treatment of the Portfolios or their shareholders, and the discussion
here and in the applicable Prospectus is not intended as a substitute for
careful tax planning.  Potential investors should consult their tax advisers
with specific reference to their own tax situations.

    
GENERAL     

     Each Portfolio will elect to be taxed separately as a regulated investment
company under Part I of Subchapter M of Subtitle A, Chapter 1 of the Internal
Revenue Code of 1986, as amended (the "Code").  As a regulated investment
company, each Portfolio generally is exempt from Federal income tax on its net
investment income and realized capital gains which it distributes to
shareholders, provided that it distributes an amount equal to at least 90% of
its investment company taxable income (net investment income and the excess of
net short-term capital gain over net long-term capital loss), if any, for the
year (the "Distribution Requirement") and satisfies certain other requirements
of the Code that are described below.

     In addition to satisfying the Distribution Requirement, each Portfolio must
derive with respect to a taxable year at least 90% of its gross income from
dividends, interest, certain payments with respect to securities loans and gains
from the sale or other disposition of stock or securities or foreign currencies,
or from other income derived with respect to its business of investing in such
stock, securities or currencies (the "Income Requirement").

    
     In addition to the foregoing requirements, at the close of each quarter of
its taxable year, at least 50% of the value of each Portfolio's assets must
consist of cash and cash items, U.S.  Government securities, securities of other
regulated investment companies, and securities of other issuers (as to which the
Portfolio has not invested more than 5% of the value of its total assets in
securities of such issuer and as to which the Portfolio does not hold more than
10% of the outstanding voting securities of such issuer) and no more than 25% of
the value of each Portfolio's total assets may be invested in the securities of
any one issuer (other than U.S.  Government securities and securities of other
regulated investment companies), or in two or more issuers which such Portfolio
controls and which are engaged in the same or similar trades or businesses.     

     Each Portfolio intends to distribute to shareholders any excess of net
long-term capital gain over net short-term capital loss ("net capital gain") for
each taxable year.  Such gain is

                                     B-55    
<PAGE>
 
    
distributed as a capital gain dividend and is taxable to shareholders as long-
term capital gain (20% or 28% rate gain, as applicable), regardless of the
length of time the shareholder has held the shares, whether such gain was
recognized by the Portfolio prior to the date on which a shareholder acquired
shares of the Portfolio and whether the distribution was paid in cash or
reinvested in shares.  In addition, investors should be aware that any loss
realized upon the sale, exchange or redemption of shares held for six months or
less will be treated as a long-term capital loss to the extent of the capital
gain dividends the shareholder has received with respect to such shares.     

     In the case of corporate shareholders, distributions of a Portfolio for any
taxable year generally qualify for the dividends received deduction to the
extent of the gross amount of "qualifying dividends" received by such Portfolio
for the year.  Generally, a dividend will be treated as a "qualifying dividend"
if it has been received from a domestic corporation.

    
     Ordinary income of individuals is taxable at a nominal maximum marginal
rate of 39.6%, but because of limitations on itemized deductions otherwise
allowable and the phase-out of personal exemptions, the maximum effective
marginal rate of tax for some taxpayers may be higher.  The maximum tax rate on
capital gains for individuals is 20% if the property was held more than 18
months; for property held for more than 12 months, but not longer than 18
months, the maximum tax rate on capital gains is 28%.  Capital gains and
ordinary income of corporate taxpayers are both taxed at a nominal maximum rate
of 35%.     

     If for any taxable year any Portfolio does not qualify as a regulated
investment company, all of its taxable income will be subject to tax at regular
corporate rates without any deduction for distributions to shareholders.  In
such event, all distributions would be taxable as ordinary income, to the extent
of such Portfolio's current and accumulated earnings and profits and would be
eligible for the dividends received deduction in the case of corporate
shareholders.

     Shareholders will be advised annually as to the Federal income tax
consequences of distributions made by the Portfolios each year.

     The Code imposes a non-deductible 4% excise tax on regulated investment
companies that fail to currently distribute an amount equal to specified
percentages of their ordinary taxable income and capital gain net income (excess
of capital gains over capital losses).  Each Portfolio intends to make
sufficient distributions or deemed distributions of its ordinary taxable income
and capital gain net income each calendar year to avoid liability for this
excise tax.

     The Trust will be required in certain cases to withhold and remit to the
United States Treasury 31% of taxable dividends or 31% of gross sale proceeds
paid to any shareholder (i) who has provided either an incorrect tax
identification number or no number at all, (ii) who is subject to backup
withholding by the Internal Revenue Service for prior failure to report the
receipt of taxable interest or dividend income properly, or (iii) who has failed
to certify to the Trust, when required to do so, that he is not subject to
backup withholding or that he is an "exempt recipient."     

TAXATION OF CERTAIN FINANCIAL INSTRUMENTS

     Special rules govern the Federal income tax treatment of financial
instruments that may be held by the Portfolios.  These rules may have a
particular impact on the amount of income or gain that the Portfolios must
distribute to their respective shareholders to comply with the Distribution
Requirement and on the income or gain qualifying under the Income Requirement
described above.

     Generally, futures contracts, options on futures contracts and certain
foreign currency contracts held by a Portfolio (collectively, the "Instruments")
at the close of its taxable year are treated for Federal income tax purposes as
sold for their fair market value on the last business day of such year, a
process known as "mark-to-market." Forty percent of any gain or loss resulting
from such constructive sales will be treated as short-term capital gain or loss
and 60% of such gain or loss will be treated as long-term capital gain or loss
without regard to the period a Portfolio has held the Instruments ("the 40%-60%
rule").  The amount of any capital gain or loss actually realized by a Portfolio
in a subsequent sale or other disposition of those Instruments is adjusted to
reflect any capital gain or loss taken into account by the Portfolio in a prior
year as a result of the constructive sale of the Instruments.  Losses with
respect to futures contracts to sell, related options and certain foreign
currency contracts, which are regarded as parts of a "mixed straddle" because
their values fluctuate inversely to the values of specific securities held by
the Portfolios, are subject to certain loss deferral rules which limit the
amount of loss currently deductible on either part of the straddle to the amount
thereof which exceeds the unrecognized gain (if any) with respect to the other
part of the straddle, and to certain wash sales regulations.  With respect to
certain Instruments, deductions for interest and carrying charges may not be
allowed.

     Notwithstanding the rules described above, with respect to futures
contracts which are part of a "mixed straddle" to sell related options and
certain foreign currency contracts which are properly identified as such, a
Portfolio may make an election which will exempt (in whole or in part) those
identified futures contracts, options and foreign currency contracts from the
Rules of

                                     B-57    
<PAGE>
 
Section 1256 of the Code including "the 40%-60% rule" and the mark-to-market on
gains and losses being treated for Federal income tax purposes as sold on the
last business day of the Portfolio's taxable year, but gains and losses will be
subject to such wash sales and loss deferral rules and the requirement to
capitalize interest and carrying charges.  Under Temporary Regulations, each
Portfolio would be allowed (in lieu of the foregoing) to elect either (1) to
offset gains or losses from portions which are part of a mixed straddle by
separately identifying each mixed straddle to which such treatment applies, or
(2) to establish a mixed straddle account for which gains and losses would be
recognized and offset on a periodic basis during the taxable year.  Under either
election, "the 40%-60% rule" will apply to the net gain or loss attributable to
the Instruments, but, in the case of a mixed straddle account election, not more
than 50% of any net gain may be treated as long-term and no more than 40% of any
net loss may be treated as short-term.

    
     Certain foreign currency contracts entered into by a Portfolio may be
subject to the "mark-to-market" process, but gain or loss will be treated as
100% ordinary income or loss.  A foreign currency contract must meet the
following conditions in order to be subject to the mark-to-market rules
described above: (1) the contract must require delivery of, or settlement by
reference to the value of, a foreign currency of a type in which regulated
futures contracts are traded; (2) the contract must be entered into at arm's
length at a price determined by reference to the price in the interbank market;
and (3) the contract must be traded in the interbank market.  The Treasury
Department has broad authority to issue regulations under the provisions
respecting foreign currency contracts.  As of the date of this Additional
Statement, the Treasury Department has not issued any such regulations.  Other
foreign currency contracts entered into by a Portfolio may result in the
creation of one or more straddles for Federal income tax purposes, in which case
certain loss deferral and wash sales rules and the requirement to capitalize
interest and carrying charges may apply.     

     Some of the non-U.S. dollar denominated investments that the Portfolios may
make, such as foreign debt securities and foreign currency contracts, may be
subject to provisions of the Code which govern the Federal income tax treatment
of certain transactions denominated in terms of a currency other than the U.S.
dollar or determined by reference to the value of one or more currencies other
than the U.S. dollar.  The types of transactions covered by these provisions
include the following: (1) the acquisition of, or becoming the obligor under, a
bond or other debt instrument (including, to the extent provided in Treasury
regulations, preferred stock); (2) the accruing of certain trade receivables and
payables; and (3) the entering into or acquisition of any forward contract,
futures contract, option and similar financial instrument.  The disposition of a
currency other than the U.S.

                                     B-58    
<PAGE>
 
dollar by a U.S. taxpayer also is treated as a transaction subject to the
special currency rules.  However, regulated futures contracts and nonequity
options are generally not subject to the special currency rules if they are or
would be treated as sold for their fair market value at year-end under the mark-
to-market rules, unless an election is made to have such currency rules apply.
With respect to transactions covered by the special rules, foreign currency gain
or loss is calculated separately from any gain or loss on the underlying
transaction and is normally taxable as ordinary gain or loss.  A taxpayer may
elect to treat as capital gain or loss foreign currency gain or loss arising
from certain identified forward contracts, futures contracts and options that
are capital assets in the hands of the taxpayer and which are not part of a
straddle.  In accordance with Treasury regulations, certain transactions that
are part of a "Section 988 hedging transaction" (as defined in the Code and
Treasury regulations) may be integrated and treated as a single transaction or
otherwise treated consistently for purposes of the Code.  "Section 988 hedging
transactions" are not subject to the mark-to-market or loss deferral rules under
the Code.  Gain or loss attributable to the foreign currency component of
transactions engaged in by the Portfolios which are not subject to the special
currency rules (such as foreign equity investments other than certain preferred
stocks) is treated as capital gain or loss and is not segregated from the gain
or loss on the underlying transaction.

     Foreign shareholders generally will be subject to U.S. withholding tax at a
rate of 30% (or a lower treaty rate, if applicable) on distributions by a
Portfolio of net interest income, other ordinary income, and the excess, if any,
of net short-term capital gain over net long-term capital loss for the year.
For this purpose, foreign shareholders include individuals other than U.S.
citizens, residents and certain nonresident aliens, and foreign corporations,
partnerships, trusts and estates.  A foreign shareholder generally will not be
subject to U.S.  income or withholding tax in respect of proceeds from or gain
on the redemption of shares or in respect of capital gain dividends, provided
such shareholder submits a statement, signed under penalties of perjury,
attesting to such shareholder's exempt status.  Different tax consequences apply
to a foreign shareholder engaged in a U.S.  trade or business.  Foreign
shareholders should consult their tax advisers regarding the U.S. and foreign
tax consequences of investing in a Portfolio.     

CONCLUSION

    
     The foregoing discussion is based on Federal tax laws and regulations which
are in effect on the date of this Additional Statement.  Such laws and
regulations may be changed by legislative or administrative action.  No attempt
is made to present a detailed     

                                     B-59    
<PAGE>
 
explanation of the tax treatment of the Portfolio or its shareholders, and the
discussion here and in the Prospectus is not intended as a substitute for
careful tax planning.  Shareholders are advised to consult their tax advisers
with specific reference to their own tax situation, including the application of
state and local taxes.

     Although each Portfolio expects to qualify as a "regulated investment
company" and to be relieved of all or substantially all Federal income taxes,
depending upon the extent of its activities in states and localities in which
its offices are maintained, in which its agents or independent contractors are
located or in which it is otherwise deemed to be conducting business, each
Portfolio may be subject to the tax laws of such states or localities.

                             DESCRIPTION OF SHARES

    
     The Trust Agreement permits the Trust's Board of Trustees to issue an
unlimited number of full and fractional shares of beneficial interest of one or
more separate series representing interests in one or more investment
portfolios.  The Trust may hereafter create series in addition to the Trust's
eighteen existing series, which represent interests in the Trust's eighteen
respective portfolios, seven of which are discussed in this Additional
Statement.  The Trust Agreement further permits the Board of Trustees to
classify or reclassify any unissued shares into additional series or classes
within a series.  Pursuant to such authority, the Trustees have authorized the
issuance of an unlimited number of shares of beneficial interest in four
separate classes of shares in each of the Trust's non-money market portfolios:
Class A, B, C and D Shares.  Under the terms of the Trust Agreement, each share
of each Portfolio is without par value, represents an equal proportionate
interest in the particular Portfolio with each other share of its class in the
same Portfolio and is entitled to such dividends and distributions out of the
income belonging to the Portfolio as are declared by the Trustees.  Upon any
liquidation of a Portfolio, shareholders of each class of a Portfolio are
entitled to share pro rata in the net assets belonging to that class available
for distribution.  Shares do not have any preemptive or conversion rights.  The
right of redemption is described under "Investing-Redemption of Shares" in the
Prospectus.  In addition, pursuant to the terms of the 1940 Act, the right of a
shareholder to redeem shares and the date of payment by a Portfolio may be
suspended for more than seven days (a) for any period during which the New York
Stock Exchange is closed, other than the customary weekends or holidays, or
trading in the markets the Portfolio normally utilizes is closed or is
restricted as determined by the SEC, (b) during any emergency, as determined by
the SEC, as a result of which it is not reasonably practicable for the Portfolio
to dispose of instruments owned by it or fairly to determine the value of its
net assets, or (c) for such other period as the SEC may by order permit for the
protection of the     

                                     B-60    
<PAGE>
 
    
shareholders of the Portfolio.  The Trust may also suspend or postpone the
recordation of the transfer of its shares upon the occurrence of any of the
foregoing conditions.  In addition, shares of each Portfolio are redeemable at
the unilateral option of the Trust if the Trustees determine in their sole
discretion that failure to so redeem may have material adverse consequences to
the shareholders of the Portfolio.  Shares when issued as described in the
Prospectus are validly issued, fully paid and nonassessable, except as stated
below.     

     The proceeds received by each Portfolio for each 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 and constitute the underlying assets of that Portfolio.  The underlying
assets of each Portfolio will be segregated on the books of account, and will be
charged with the liabilities in respect to that Portfolio and with a share of
the general liabilities of the Trust.  Expenses with respect to the Portfolios
are normally allocated in proportion to the net asset value of the respective
Portfolios except where allocations of direct expenses can otherwise be fairly
made.

    
     Rule 18f-2 under the 1940 Act provides that any matter required by the
provisions of the 1940 Act or applicable state law, or otherwise, to be
submitted 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 investment portfolio affected by such matter.  Rule 18f-2 further provides
that an investment portfolio shall be deemed to be affected by a matter unless
the interests of each investment portfolio in the matter are substantially
identical or the matter does not affect any interest of the investment
portfolio.  Under the Rule, the approval of an investment advisory agreement or
any change in a fundamental investment policy would be effectively acted upon
with respect to an investment portfolio only if approved by a majority of the
outstanding shares of such investment portfolio.  However, the Rule also
provides that the ratification of the appointment of independent accountants,
the approval of principal underwriting contracts and the election of Trustees
are exempt from the separate voting requirements stated above.  In addition,
shareholders of each of the classes in a particular investment portfolio have
equal voting rights except that only shares of a particular class of an
investment portfolio will be entitled to vote on matters submitted to a vote of
shareholders (if any) relating to shareholder servicing expenses and transfer
agency fees that are payable by that class.     

    
     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     

                                     B-61    
<PAGE>
 
    
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 Shareholders, including the election of Trustees (this
method of voting being referred to as "dollar-based voting").  However, to the
extent required by the 1940 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 meeting.  The Shareholders
of the Trust will have voting rights only with respect to the limited number of
matters specified in the Trust Agreement and such other matters as the Trustees
may determine or may be required by law.     

    
     The Trust Agreement authorizes the Trustees, without Shareholder approval
(except as stated in the next paragraph), 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
substantially all of the assets of a series of the Trust in the securities of
another open-end investment company or pooled portfolio.     

    
     The Trust Agreement also authorizes the Trustees, in connection with the
merger, consolidation, termination or other reorganization of the Trust or any
series or class, to classify the Shareholders of any class into one or more
separate groups and to provide for the different treatment of Shares held by the
different groups, provided that such merger, consolidation, termination or other
reorganization is approved by a majority of the outstanding voting securities
(as defined in the 1940 Act) of each group of Shareholders that are so
classified.     

    
     The Trust Agreement permits the Trustees to amend the Trust Agreement
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 voting provisions of the Trust Agreement; or (iv) that the
Trustees determine to submit to Shareholders.     

    
     The Trust Agreement 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     

                                     B-62    
<PAGE>
 
    
that the Trustees may take into account in making such determination include (i)
the inability of the Trust or any 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.     

     Under the Delaware Business Trust Act (the "Delaware Act"), shareholders
are not personally liable for obligations of the Trust.  The Delaware Act
entitles the Trust to the same limitation of liability as is available to
shareholders of private for-profit corporations.  However, no similar statutory
or other authority limiting business trust shareholder liability exists in many
other states.  As a result, to the extent that the Trust, business trust or a
shareholder is subject to the jurisdiction of courts in such other states, those
courts may not apply Delaware law and may subject the shareholders to liability.
To offset this risk, the Trust Agreement (i) contains an express disclaimer of
shareholder liability for acts or obligations of the Trust and requires that
notice of such disclaimer be given in each agreement, obligation and instrument
entered into or executed by the Trust or its Trustees and (ii) provides for
indemnification out of the property of the applicable series of the Trust of any
shareholder held personally liable for the obligations of the Trust 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.  Thus, the risk of a
shareholder incurring financial loss beyond his or her investment because of
shareholder liability is limited to circumstances in which all of the following
factors are present: (1) a court refuses to apply Delaware law; (2) the
liability arises under tort law or, if not, no contractual limitation of
liability is in effect; and (3) the applicable series of the Trust is unable to
meet its obligations.

    
     The Trust Agreement provides that the Trustees will not be liable to any
person other than the Trust or a shareholder and that a Trustee will not be
liable for any act as a Trustee. However, nothing in the Trust Agreement
protects a Trustee against any 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.
The Trust Agreement provides for indemnification of Trustees, officers and
agents of the Trust unless the recipient is 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.     

    
     The Trust Agreement provides that each shareholder, by virtue of becoming
such, will be held to have expressly assented and agreed to the terms of the
Trust Agreement and to have become a party thereto.     

                                     B-63    
<PAGE>
 
    
     In addition to the requirements of Delaware law, the Trust Agreement
provides that a Shareholder of the Trust may bring a derivative action on behalf
of the Trust 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 Trust, or 10% of the outstanding Shares 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 Shareholder request and to
investigate the basis of such claim.  The Trust Agreement also provides that no
person, other than the Trustees, who is not a Shareholder of a particular series
or class shall be entitled to bring any derivative action, suit or other
proceeding on behalf of or with respect to such series or class.  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 Shareholders 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 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 Trust
Agreement with respect to such 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.     

    
     As of March _____, 1998, substantially all of the Portfolios' outstanding
shares were held of record by Northern for the benefit of its customers and the
customers of its affiliates and correspondent banks that have invested in the
Portfolios.  As of the same date, the Trust's Trustees and officers owned
beneficially less than 1% of the outstanding shares of each Portfolio.  Northern
has advised the Trust that the following persons (whose mailing address is: c/o
The Northern Trust Company, 50 South LaSalle, Chicago, IL 60675) beneficially
owned five percent or more of the outstanding shares of the following Portfolios
as of March _____, 1998:

                                   APPENDIX A

DESCRIPTION OF BOND RATINGS

The following summarizes the highest six ratings used by Standard & Poor's
Ratings Group, Inc., a division of McGraw Hill ("S&P") for corporate and
municipal debt:

    
     AAA:  Debt rated AAA has the highest rating assigned by S&P. The obligor's
     capacity to meet its financial commitment on the obligation is extremely
     strong.     

    
     AA:  Debt rated AA differs from AAA issues only in a small degree.  The
     obligor's capacity to meet its financial commitment on the obligation is
     very strong.     

    
     A:  Debt rated A is somewhat more susceptible to the adverse effects of
     changes in circumstances and economic conditions than debt in higher rated
     categories.  However, the obligor's capacity to meet its financial
     commitment on the obligation is still strong.     

    
     BBB:  Debt 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.     

    
     BB AND B:  Debt rated BB and B is regarded, on balance, as predominantly
     speculative with respect to capacity to pay interest and repay principal in
     accordance with the terms of the obligation.  Debt rated BB is less
     vulnerable to non-payment 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.  Debt rated B is more
     vulnerable to non-payment but the obligor currently has the capacity to
     meet its financial commitment on the obligation.  Adverse business,
     financial, or economic conditions will likely impair the obligor's capacity
     or willingness to meet its financial commitment on the obligation.  The B
     rating category is also used for debt subordinated to senior debt that is
     assigned an actual or implied BB or BB- rating.     

To provide more detailed indications of credit quality, the ratings AA and lower
may be modified by the addition of a plus or minus sign to show relative
standing within these major rating categories.

S&P may attach the rating "r" to highlight derivative, hybrid and certain other
obligations that S&P believes may experience high

                                      1-A

volatility or high variability in expected returns due to non-credit risks.

The following summarizes the highest six ratings used by Moody's Investors
Service, Inc.  ("Moody's") for corporate and municipal long-term debt:

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

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

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

     BAA:  Bonds that are rated Baa are considered 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 AND B:  Bonds that possess one of these ratings provide questionable
     protection of interest and principal.  Ba indicates some speculative
     elements.  B indicates a general lack of characteristics of desirable
     investment.

The foregoing ratings for corporate and municipal long-term debt are sometimes
presented in parenthesis preceded with a "con", indicating the bonds are rated
conditionally.  Such parenthetical rating denotes the probable credit stature
upon completion of some act or the fulfillment of some condition.  The notation
(P) when applied to forward delivery bonds indicates that the rating is

                                      2-A    
<PAGE>
 
provisional pending delivery of the bonds.  The rating may be revised prior to
delivery if changes occur in the legal documents or the underlying credit
quality of the bonds.

The following summarizes the highest six ratings used by Duff & Phelps Credit
Rating Co.  ("D&P") for corporate and municipal long-term debt:

     AAA:  Debt rated AAA is of the highest credit quality.  The risk factors
     are considered to be negligible, being only slightly more than for risk-
     free U.S. Treasury debt.

     AA:  Debt rated AA is of high credit quality.  Protection factors are
     strong.  Risk is modest but may vary slightly from time to time because of
     economic conditions.

     A:  Bonds that are rated A have protection factors which are average but
     adequate.  However risk factors are more variable and greater in periods of
     economic stress.

     BBB:  Bonds that are rated BBB have below average protection factors but
     such protection factors are still considered sufficient for prudent
     investment.  Considerable variability in risk during economic cycles.

     BB AND B:  Bonds that are rated BB or B are below investment grade.  Bonds
     rated BB are deemed likely to meet obligations when due.  Bonds rated B
     possess the risk that the obligations will not be met when due.

To provide more detailed indications of credit quality, the ratings AA and lower
may be modified by the addition of a plus or minus sign to show relative
standing within these major categories.

The following summarizes the highest six ratings used by Fitch IBCA, Inc.
("Fitch") 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 investment risk
     and are assigned only in case of exceptionally strong capacity for timely
     payment of financial commitments.  This capacity is unlikely to be affected
     by reasonably foreseeable events.     

    
     AA:  Bonds considered to be investment grade and of very high credit
     quality.  These ratings denote a very low expectation of investment risk
     and indicate very strong capacity for timely payment of financial
     commitments.  This capacity is not significantly vulnerable to foreseeable
     events.  Because bonds rated in the "AAA" and "AA" categories are not
     significantly vulnerable to foreseeable future developments, short-term
     debt of these issuers is generally rated "F1+."     

                                      3-A    
<PAGE>
 
    
     A:  Bonds considered to be investment grade and of high credit quality.
     These ratings denote a low expectation of investment risk and indicate
     strong capacity for timely payment of financial commitments. This capacity
     may, nevertheless, be more vulnerable to adverse changes in economic
     conditions and circumstances than bonds with 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
     investment risk.  The capacity for timely payment of financial commitments
     is adequate, but adverse changes in economic conditions and circumstances,
     however, are more likely to impair this category.     

    
     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.     

To provide more detailed indications of credit quality, the Fitch ratings "AA"
and lower may be modified by the addition of a plus (+) or minus (-) sign to
show relative standing within these major rating categories.


DESCRIPTION OF MUNICIPAL NOTE RATINGS

The following summarizes the two highest ratings by S&P for short-term municipal
notes:

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

     SP-2:  Satisfactory capacity to pay principal and interest.

The following summarizes the two highest ratings used by Moody's for short-term
municipal notes and variable rate demand obligations:

     MIG-1/VMIG-1:  Obligations bearing these designations are of the best
     quality, enjoying strong protection by established

                                      4-A    
<PAGE>
 
     cash flows, superior liquidity support or demonstrated broad-based access
     to the market for refinancing.

     MIG-2/VMIG-2:  Obligations bearing these designations are of high quality
     with margins of protection ample although not as large as in the preceding
     group.

    
The two highest rating categories of D&P for short-term debt are D-1 and D-2.
D&P employs three designations, D-1+, D-1 and D-1-, within the highest rating
category.  D-1+ indicates 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 indicates very high certainty of timely
payment.  Liquidity factors are excellent and supported by good fundamental
protection factors.  Risk factors are minor.  D-1- indicates high certainty of
timely payment.  Liquidity factors are strong and supported by good fundamental
protection factors.  Risk factors are very small.  D-2 indicates 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&P uses the fixed-income ratings described above under "Description of Bond
Ratings" for tax-exempt notes and other short-term obligations.  Fitch uses the
short-term ratings described below under "Description of Commercial Paper
Ratings" for municipal notes.

DESCRIPTION OF COMMERCIAL PAPER RATINGS

    
Commercial paper rated A-1 by S&P indicates that the obligor's capacity to meet
its financial commitment is strong.  Those issues for which the obligor's
capacity to meet its financial commitment on the obligation is extremely strong
are denoted in A-1+.  Capacity for timely payment on commercial paper rated A-2
is satisfactory but the obligor's capacity to meet its financial commitment on
the obligation is not as high as for issues designated A-1.     

The rating Prime-1 is the highest commercial paper rating assigned by Moody's.
Issuers or related supporting institutions rated Prime-1 are considered to have
a superior capacity for repayment of short-term promissory obligations.  Prime-1
repayment capacity will often be evidenced by the following characteristics:
leading market positions in well-established industries; high rates of return on
funds employed; conservative capitalization structures with moderate reliance on
debt and ample asset protection; broad margins in earning 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.

                                      5-A    
<PAGE>
 
Issuers or related supporting institutions rated Prime-2 are considered to have
strong capacity for repayment of short-term promissory 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, will be more subject
to variation.  Capitalization characteristics, while still appropriate, may be
more affected by external conditions.  Ample alternate liquidity is maintained.

The following summarizes the highest ratings used by Fitch for short-term
obligations:

    
     F1+ securities possess exceptionally strong credit quality.  Issues
     assigned this rating are regarded as having the strongest degree of
     assurance for timely payment.     

    
     F1 securities possess very strong credit quality.  Issues assigned this
     rating reflect an assurance of timely payment only slightly less in degree
     than issues rated F1+.     

    
     F2 securities possess good credit quality.  Issues assigned this rating
     have a satisfactory degree of assurance for timely payment, but the margin
     of safety is not as great as the F1+ and F1 categories.     

D&P uses the short-term ratings described above under "Description of Note
Ratings" for commercial paper.

                                   APPENDIX B

As stated in their Prospectus, the Portfolios may enter into futures
transactions and options thereon.  Such transactions are described more fully in
this Appendix.

I.   INTEREST RATE FUTURES CONTRACTS

     Use of Interest Rate Futures Contracts.  Bond prices are established in
     --------------------------------------                                 
both the cash market and the futures market.  In the cash market, bonds are
purchased and sold with payment for the full purchase price of the bond being
made in cash, generally within three business days after the trade.  In the
futures market, only a contract is made to purchase or sell a bond in the future
for a set price on a certain date.  Historically, the prices for bonds
established in the futures markets have tended to move generally in the
aggregate in concert with the cash market prices and have maintained fairly
predictable relationships.  Accordingly, a Portfolio could use interest rate
futures contracts as a defense, or hedge, against anticipated interest rate
changes. As described below, this could include the use of futures contract
sales to protect against expected increases in interest rates and the use of
futures contract purchases to offset the impact of interest rate declines.

     A Portfolio presently could accomplish a similar result to that which it
hopes to achieve through the use of futures contracts by selling bonds with long
maturities and investing in bonds with short maturities when interest rates are
expected to increase, or conversely, selling short-term bonds and investing in
long-term bonds when interest rates are expected to decline.  However, because
of the liquidity that is often available in the futures market, the protection
is more likely to be achieved, perhaps at a lower cost and without changing the
rate of interest being earned by a Portfolio, through using futures contracts.

     Interest rate futures contracts can also be used by a portfolio for
nonhedging (speculative) purposes to increase total return.

     Description of Interest Rate Futures Contracts.  An interest rate futures
     ----------------------------------------------                           
contract sale would create an obligation by a Portfolio, as seller, to deliver
the specific type of financial instrument called for in the contract at a
specific future time for a specified price.  A futures contract purchase would
create an obligation by a Portfolio, as purchaser, to take delivery of the
specific type of financial instrument at a specific future time at a specific
price.  The specific securities delivered or taken, respectively, at settlement
date, would not be determined until at or near that date.  The determination
would be in accordance with the rules of the exchange on which the futures
contract sale or purchase was made.

                                     1-B     
<PAGE>
 
     Although interest rate futures contracts by their terms call for actual
delivery or acceptance of securities, in most cases the contracts are closed out
before a settlement date without the making or taking of delivery of securities.
Closing out a futures contract sale is effected by a Portfolio's entering into a
futures contract purchase for the same aggregate amount of the specific type of
financial instrument and the same delivery date. If the price of a sale exceeds
the price of the offsetting purchase, a Portfolio is immediately paid the
difference and thus realizes a gain.  If the offsetting purchase price exceeds
the sale price, a Portfolio pays the difference and realizes a loss. Similarly,
the closing out of a futures contract purchase is effected by a Portfolio
entering into a futures contract sale. If the offsetting sale price exceeds the
purchase price, a Portfolio realizes a gain, and if the purchase price exceeds
the offsetting sale price, a Portfolio realizes a loss.

     Interest rate futures contracts are traded in an auction environment on the
floors of several exchanges -- principally, the Chicago Board of Trade, the
Chicago Mercantile Exchange and the New York Futures Exchange.  A Portfolio
would deal only in standardized contracts on recognized exchanges.  Each
exchange guarantees performance under contract provisions through a clearing
corporation, a nonprofit organization managed by the exchange membership.

     A public market now exists in futures contracts covering various financial
instruments including long-term United States Treasury Bonds and Notes;
Government National Mortgage Association (GNMA) modified pass-through mortgage
backed securities; three-month United States Treasury Bills; and ninety-day
commercial paper.  A Portfolio may trade in any interest rate futures contracts
for which there exists a public market, including, without limitation, the
foregoing instruments.

II.  INDEX FUTURES CONTRACTS

     GENERAL.  A stock or bond index assigns relative values to the securities
included in the index and the index fluctuates with changes in the market values
of the securities included.

     A Portfolio may sell index futures contracts in order to offset a decrease
in market value of its portfolio securities that might otherwise result from a
market decline.  A Portfolio may do so either to hedge the value of its
portfolio as a whole, or to protect against declines, occurring prior to sales
of securities, in the value of the securities to be sold.  Conversely, a
Portfolio may purchase index futures contracts in anticipation of purchases of
securities.  A long futures position may be terminated without a corresponding
purchase of securities.

                                     2-B     
<PAGE>
 
     In addition, a Portfolio may utilize index futures contracts in
anticipation of changes in the composition of its portfolio holdings.  For
example, in the event that a Portfolio expects to narrow the range of industry
groups represented in its holdings it may, prior to making purchases of the
actual securities, establish a long futures position based on a more restricted
index, such as an index comprised of securities of a particular industry group.
A Portfolio may also sell futures contracts in connection with this strategy, in
order to protect against the possibility that the value of the securities to be
sold as part of the restructuring of the portfolio will decline prior to the
time of sale.

     Index futures contracts may also be used by a Portfolio for non-hedging
(speculative) purposes to increase total return.

III. FUTURES CONTRACTS ON FOREIGN CURRENCIES (INTERNATIONAL EQUITY INDEX AND
INTERNATIONAL GROWTH PORTFOLIOS)

     A futures contract on foreign currency creates a binding obligation on one
party to deliver, and a corresponding obligation on another party to accept
delivery of, a stated quantity of foreign currency, for an amount fixed in U.S.
dollars.  Foreign currency futures may be used by a Portfolio for hedging
purposes in anticipation of fluctuations in exchange rates between the U.S.
dollars and other currencies arising from multinational transactions.

IV.  MARGIN PAYMENTS

     Unlike purchases or sales of portfolio securities, no price is paid or
received by a Portfolio upon the purchase or sale of a futures contract.
Initially, the Portfolio will be required to deposit with the broker or in a
segregated account with the Custodian or a sub-custodian an amount of liquid
assets known as initial margin, based on the value of the contract.  The nature
of initial margin in futures transactions is different from that of margin in
security transactions in that futures contract margin does not involve the
borrowing of funds by the customer to finance the transactions.  Rather, the
initial margin is in the nature of a performance bond or good faith deposit on
the contract which is returned to the Portfolio upon termination of the futures
contract assuming all contractual obligations have been satisfied.  Subsequent
payments, called variation margin, to and from the broker, will be made on a
daily basis as the price of the underlying instruments fluctuates making the
long and short positions in the futures contract more or less valuable, a
process known as marking-to-the-market.  For example, when a particular
Portfolio has purchased a futures contract and the price of the contract has
risen in response to a rise in the underlying instruments, that position will
have increased in value and the Portfolio will be entitled to receive from the
broker a variation margin payment equal to that increase in value.  Conversely,
where

                                     3-B     
<PAGE>
 
the Portfolio has purchased a futures contract and the price of the future
contract has declined in response to a decrease in the underlying instruments,
the position would be less valuable and the Portfolio would be required to make
a variation margin payment to the broker.  At any time prior to expiration of
the futures contract, the Portfolio's adviser may elect to close the position by
taking an opposite position, subject to the availability of a secondary market,
which will operate to terminate the Portfolio's position in the futures
contract.  A final determination of variation margin is then made, additional
cash is required to be paid by or released to the Portfolio, and the Portfolio
realizes a loss or gain.

V.   RISKS OF TRANSACTIONS IN FUTURES CONTRACTS

     There are several risks in connection with the use of futures by the
Portfolios.  In connection with the use of futures for hedging purposes, the
risk arises because of the imperfect correlation between movements in the price
of the futures and movements in the price of the instruments which are the
subject of a hedge.  The price of the future may move more than or less than the
price of the instruments being hedged.  If the price of the futures moves less
than the price of the instruments which are the subject of hedge, the hedge will
not be fully effective but, if the price of the instruments being hedged has
moved in an unfavorable direction, the Portfolio would be in a better position
than if it had not hedged at all.  If the price of the instruments being hedged
has moved in a favorable direction, this advantage will be partially offset by
the loss on the futures.  If the price of the futures moves more than the price
of the hedged instruments, the Portfolio involved will experience either a loss
or gain on the futures which will not be completely offset by movements in the
price of the instruments which are the subject of the hedge.  To compensate for
the imperfect correlation of movements in the price of instruments being hedged
and movements in the price of futures contracts, the Portfolio may buy or sell
futures contracts in a greater dollar amount than the dollar amount of
instruments being hedged if the volatility over a particular time period of the
prices of such instruments has been greater than the volatility over such time
period of the futures, or if otherwise deemed to be appropriate by the
Investment Advisers.  Conversely, the Portfolios may buy or sell fewer futures
contracts if the volatility over a particular time period of the prices of the
instruments being hedged is less than the volatility over such time period of
the futures contract being used, or if otherwise deemed to be appropriate by the
Investment Advisers.  It is also possible that, where a Portfolio had sold
futures to hedge its portfolio against a decline in the market, the market may
advance and the value of instruments held in the Portfolio may decline.  If this
occurred, the Portfolio would lose money on the futures and also experience a
decline in value in its portfolio securities.

                                     4-B     
<PAGE>
 
     When futures are purchased to hedge against a possible increase in the
price of securities before a Portfolio is able to invest its cash (or cash
equivalents) in an orderly fashion, it is possible that the market may decline
instead; if the Portfolio then concludes not to invest its cash at that time
because of concern as to possible further market decline or for other reasons,
the Portfolio will realize a loss on the futures contract that is not offset by
a reduction in the price of the instruments that were to be purchased.

     In addition to the possibility that there may be an imperfect correlation,
or no correlation at all, between movements in the futures and the instruments
being hedged, the price of futures may not correlate perfectly with movement in
the cash market due to certain market distortions.  Rather than meeting
additional margin deposit requirements, investors may close futures contracts
through off-setting transactions which could distort the normal relationship
between the cash and futures markets.  Second, with respect to financial futures
contracts, the liquidity of the futures market depends on participants entering
into off-setting transactions rather than making or taking delivery.  To the
extent participants decide to make or take delivery, liquidity in the futures
market could be reduced thus producing distortions.  Third, from the point of
view of speculators, the deposit requirements in the futures market are less
onerous than margin requirements in the securities market.  Therefore, increased
participation by speculators in the futures market may also cause temporary
price distortions.  Due to the possibility of price distortion in the futures
market, and because of the imperfect correlation between the movements in the
cash market and movements in the price of futures, a correct forecast of general
market trends or interest rate movements by the Investment Advisers may still
not result in a successful hedging transaction over a short time frame.

     Positions in futures may be closed out only on an exchange or board of
trade which provides a secondary market for such futures.  Although the
Portfolios intend to purchase or sell futures only on exchanges or boards of
trade where there appear to be active secondary markets, there is no assurance
that a liquid secondary market on any exchange or board of trade will exist for
any particular contract or at any particular time.  In such event, it may not be
possible to close a futures investment position, and in the event of adverse
price movements, the Portfolios would continue to be required to make daily cash
payments of variation margin.  However, in the event futures contracts have been
used to hedge portfolio securities, such securities will generally not be sold
until the futures contract can be terminated.  In such circumstances, an
increase in the price of the securities, if any, may partially or completely
offset losses on the futures contract.  However, as described above, there is no
guarantee that the price of the securities will in fact correlate with the price
movements

                                     5-B     
<PAGE>
 
in the futures contract and thus provide an offset on a futures contract.

     Further, it should be noted that the liquidity of a secondary market in a
futures contract may be adversely affected by "daily price fluctuation limits"
established by commodity exchanges which limit the amount of fluctuation in a
futures contract price during a single trading day.  Once the daily limit has
been reached in the contract, no trades may be entered into at a price beyond
the limit, thus preventing the liquidation of open futures positions.  The
trading of futures contracts is also subject to the risk of trading halts,
suspensions, exchange or clearing house equipment failures, government
intervention, insolvency of a brokerage firm or clearing house or other
disruptions of normal activity, which could at times make it difficult or
impossible to liquidate existing positions or to recover excess variation margin
payments.

    
     Successful use of futures by the Portfolios is also subject to the
Investment Advisers' ability to predict correctly movements in the direction of
the market.  For example, if a particular Portfolio has hedged against the
possibility of a decline in the market adversely affecting securities held by it
and securities prices increase instead, the Portfolio will lose part or all of
the benefit to the increased value of its securities which it has hedged because
it will have offsetting losses in its futures positions.  In addition, in such
situations, if the Portfolio has insufficient cash, it may have to sell
securities to meet daily variation margin requirements.  Such sales of
securities may be, but will not necessarily be, at increased prices which
reflect the rising market.  The Portfolios may have to sell securities at a time
when they may be disadvantageous to do so.     

     Futures purchased or sold by the International Growth and International
Equity Portfolios (and related options) may be traded in foreign securities.
Participation in foreign futures and foreign options transactions involves the
execution and clearing of trades on or subject to the rules of a foreign board
of trade.  Neither the National Futures Association nor any domestic exchange
regulates activities of any foreign boards of trade, including the execution,
delivery and clearing of transactions, or has the power to compel enforcement of
the rules of a foreign 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, customers who trade foreign futures of foreign options contracts
may not be afforded certain of the protective measures provided by the Commodity
Exchange Act, the Commodity Futures Trading Commission's ("CFTC") regulations
and the rules of the National Futures Association and any domestic

                                     6-B     
<PAGE>
 
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, the investments of the International
Growth Portfolio and International Equity Index Portfolio in foreign futures or
foreign options transactions may not be provided the same protections in respect
of transactions on United States futures exchanges.  In addition, the price of
any foreign futures or foreign options contract and, therefore the potential
profit and loss thereon may be affected by any variance in the foreign exchange
rate between the time an order is placed and the time it is liquidated, offset
or exercised.

VI.  OPTIONS ON FUTURES CONTRACTS

     The Portfolios may purchase and write options on the futures contracts
described above.  A futures option gives the holder, in return for the premium
paid, the right to buy (call) from or sell (put) to the writer of the option a
futures contract at a specified price at any time during the period of the
option.  Upon exercise, the writer of the option is obligated to pay the
difference between the cash value of the futures contract and the exercise
price.  Like the buyer or seller of a futures contract, the holder, or writer,
of an option has the right to terminate its position prior to the scheduled
expiration of the option by selling, or purchasing an option of the same series,
at which time the person entering into the closing transaction will realize a
gain or loss.  A Portfolio will be required to deposit initial margin and
variation margin with respect to put and call options on futures contracts
written by it pursuant to brokers' requirements similar to those described
above.  Net option premiums received will be included as initial margin
deposits.

     Investments in futures options involve some of the same considerations that
are involved in connection with investments in futures contracts (for example,
the existence of a liquid secondary market).  See "Risks of Transactions in
Futures Contracts" above.  In addition, the purchase or sale of an option also
entails the risk that changes in the value of the underlying futures contract
will not correspond to changes in the value of the option purchased.  Depending
on the pricing of the option compared to either the futures contract upon which
it is based, or upon the price of any underlying instruments, an option may or
may not be less risky than ownership of the futures contract or such
instruments.  In general, the market prices of options can be expected to be
more volatile than the market prices on the underlying futures contract.
Compared to the purchase or sale of futures contracts, however, the purchase of
call or put options on futures contracts may, unlike futures contracts where the
risk of loss is potentially unlimited, frequently involve less potential risk to
the Portfolio because the maximum amount at risk is the premium paid for the
options (plus transaction costs).  The writing

                                     7-B

of an option on a futures contract involves risks similar to those risks
relating to the sale of futures contracts.

VII. OTHER MATTERS

     Accounting for futures contracts will be in accordance with generally
accepted accounting principles.

ADDITIONAL INVESTMENT INFORMATION

Investment Objectives and Policies
    
The following supplements the investment objectives and policies of the U.S.
Government Securities, Short-Intermediate Bond, U.S. Treasury Index, Bond,
Intermediate Bond and International Bond Portfolios (the "Portfolios") of The
Benchmark Funds (the "Trust") as set forth in the Prospectus.     

U.S. Government Obligations.  Examples of other types of U.S.  Government
obligations that may be acquired by the Portfolios include U.S. Treasury Bills,
Treasury Notes and Treasury Bonds and the obligations of Federal Home Loan
Banks, Federal Farm Credit Banks, Federal Land Banks, the Federal Housing
Administration, Farmers Home Administration, Export-Import Bank of the United
States, Small Business Administration, General Services Administration, Central
Bank for Cooperatives, Federal Home Loan Mortgage Corporation, Federal
Intermediate Credit Banks, and the Maritime Administration.

Supranational Bank Obligations.  Each Portfolio (other than the U.S. Treasury
Index Portfolio) may invest in obligations of supranational banks.
Supranational banks are international banking institutions designed or supported
by national governments to promote economic reconstruction, development or trade
between nations (e.g., the World Bank).  Obligations of supranational banks may
be supported by appropriated but unpaid commitments of their member countries
and there is no assurance that these commitments will be undertaken or met in
the future.

Stripped Securities.  The Treasury Department has facilitated transfers of
ownership of zero coupon securities by accounting separately for the beneficial
ownership of particular interest coupon and principal payments on Treasury
securities through the Federal Reserve book-entry record-keeping system.  The
Federal Reserve program as established by the Treasury Department is known as
"STRIPS" or "Separate Trading of Registered Interest and Principal of
Securities." Each Portfolio may purchase securities registered in the STRIPS
program.  Under the STRIPS program, a Portfolio will be able to have its
beneficial ownership of zero coupon securities recorded directly in the book-
entry record-keeping system in lieu of having to hold certificates or other
evidences of ownership of the underlying U.S. Treasury securities.

In addition, each Portfolio (other than the U.S. Treasury Index Portfolio) may
acquire U.S. Government obligations and their unmatured interest coupons that
have been separated ("stripped") by their holder, typically a custodian bank or
investment brokerage firm.  Having separated the interest coupons from the
underlying principal of the U.S. Government obligations, the holder will resell
the stripped securities in custodial receipt programs with

                                      B-3
<PAGE>
 
a number of different names, including "Treasury Income Growth Receipts"
("TIGRs") and "Certificate of Accrual on Treasury Securities" ("CATS").  The
stripped coupons are sold separately from the underlying principal, which is
usually sold at a deep discount because the buyer receives only the right to
receive a future fixed payment on the security and does not receive any rights
to periodic interest (cash) payments.  The underlying U.S. Treasury bonds and
notes themselves are held in book-entry form at the Federal Reserve Bank or, in
the case of bearer securities (i.e., unregistered securities which are
ostensibly owned by the bearer or holder), in trust on behalf of the owners.
Counsel to the underwriters of these certificates or other evidences of
ownership of U.S. Treasury securities have stated that, in their opinion,
purchasers of the stripped securities most likely will be deemed the beneficial
holders of the underlying U.S. Government obligations for Federal tax purposes.
The Trust is not aware of any binding legislative, judicial or administrative
authority on this issue.

To the extent consistent with its investment objectives, each Portfolio may
purchase stripped mortgage-backed securities ("SMBS").  SMBS are usually
structured with two or more classes that receive different proportions of the
interest and principal distributions from a pool of mortgage-backed obligations.
A common type of SMBS will have one class receiving all of the interest, while
the other class receives all of the principal.  However, in some instances, one
class will receive some of the interest and most of the principal while the
other class will receive most of the interest and the remainder of the
principal.  If the underlying obligations experience greater than anticipated
prepayments of principal, the Portfolio may fail to fully recoup its initial
investment in these securities.  The market value of the class consisting
entirely of principal payments generally is extremely volatile in response to
changes in interest rates.  The yields on a class of SMBS that receives all or
most of the interest are generally higher than prevailing market yields on other
mortgage-backed obligations because their cash flow patterns are also volatile
and there is a risk that the initial investment will not be fully recouped.
SMBS issued by the U.S. Government (or a U.S. Government agency or
instrumentality) may be considered liquid under guidelines established by the
Trust's Board of Trustees if they can be disposed of promptly in the ordinary
course of business at a value reasonably close to that used in the calculation
of the net asset value per share.

Asset-Backed Securities.  The U.S. Government Securities Portfolio may purchase
securities that are secured or backed by mortgages and issued by an agency of
the U.S. Government, and the Short-Intermediate Bond, Bond, Intermediate Bond
and International Bond Portfolios may purchase asset-backed securities, which
are securities backed by mortgages, installment contracts, credit card
receivables or other assets.  Asset-backed securities represent

                                      B-4
<PAGE>
 
interests in "pools" of assets in which payments of both interest and principal
on the securities are made monthly, thus in effect "passing through" monthly
payments made by the individual borrowers on the assets that underlie the
securities, net of any fees paid to the issuer or guarantor of the securities.
The average life of asset-backed securities varies with the maturities of the
underlying instruments, and the average life of a mortgage-backed instrument, in
particular, is likely to be substantially less than the original maturity of the
mortgage pools underlying the securities as a result of mortgage prepayments.
For this and other reasons, an asset-backed security's stated maturity may be
shortened, and the security's total return may be difficult to predict
precisely.  Asset-backed securities acquired by a Portfolio may include
collateralized mortgage obligations ("CMOs") issued by private companies.

There are a number of important differences among the agencies and
instrumentalities of the U.S.  Government that issue mortgage-related securities
and among the securities that they issue.  Mortgage-related securities
guaranteed by the Government National Mortgage Association ("GNMA") include GNMA
Mortgage Pass-Through Certificates (also known as "Ginnie Maes") which are
guaranteed as to the timely payment of principal and interest by GNMA and such
guarantee is backed by the full faith and credit of the United States.  GNMA is
a wholly-owned U.S.  Government corporation within the Department of Housing and
Urban Development.  GNMA certificates also are supported by the authority of
GNMA to borrow funds from the U.S.  Treasury to make payments under its
guarantee.  Mortgage-backed securities issued by the Federal National Mortgage
Association ("FNMA") include FNMA Guaranteed Mortgage Pass-Through Certificates
(also known as "Fannie Maes") which are solely the obligations of the FNMA and
are not backed by or entitled to the full faith and credit of the United States,
but are supported by the right of the issuer to borrow from the U.S. Treasury.
FNMA is a government-sponsored organization owned entirely by private
stockholders.  Fannie Maes are guaranteed as to timely payment of the principal
and interest by FNMA.  Mortgage-related securities issued by the Federal Home
Loan Mortgage Corporation ("FHLMC") include FHLMC Mortgage Participation
Certificates (also known as "Freddie Macs" or "PCs").  FHLMC is a corporate
instrumentality of the United States, created pursuant to an Act of Congress,
which is owned entirely by Federal Home Loan Banks.  Freddie Macs are not
guaranteed by the United States or by any Federal Home Loan Banks and do not
constitute a debt or obligation of the United States or of any Federal Home Loan
Bank.  Freddie Macs entitle the holder to timely payment of interest, which is
guaranteed by the FHLMC.  FHLMC guarantees either ultimate collection or timely
payment of all principal payments on the underlying mortgage loans.  When FHLMC
does not guarantee timely payment of principal, FHLMC may remit the amount due
on account of its guarantee of ultimate payment of principal at any time after
default on an underlying

                                      B-5
<PAGE>
 
mortgage, but in no event later than one year after it becomes payable.

Non-mortgage asset-backed securities involve certain risks that are not
presented by mortgage-backed securities.  Primarily, these securities do not
have the benefit of the same security interest in the underlying collateral.
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 have given debtors the right to set off certain amounts owed on the credit
cards, thereby reducing the balance due.  Most issuers of automobile receivables
permit the 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
related automobile receivables.  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 an
effective security interest in all of the obligations backing such receivables.
Therefore, there is a possibility that recoveries on repossessed collateral may
not, in some cases, be able to support payments on these securities.

Foreign Securities.  Unanticipated political or social developments may affect
the value of a Portfolio's investments in emerging market countries and the
availability to the Portfolio of additional investments in those countries.  The
small size and inexperience of the securities markets in certain of such
countries and the limited volume of trading in securities in those countries may
make the Portfolio's investments in such countries illiquid and more volatile
than investments in Japan or most Western European countries, and the Portfolio
may be required to establish special custodial or other arrangements before
making certain investments in those countries.  There may be little financial or
accounting information available with respect to issuers located in certain of
such countries, and it may be difficult as a result to assess the value or
prospects of an investment in such issuers.

Investors should understand that the expense ratio of the International Bond
Portfolio can be expected to be higher than those of funds investing in domestic
securities.  The costs attributable to investing abroad are usually higher for
several reasons, such as the higher cost of investment research, higher cost of
custody of foreign securities, higher commissions paid on comparable
transactions on foreign markets and additional costs arising from delays in
settlements of transactions involving foreign securities.

Foreign Currency Transactions.  In order to protect against a possible loss on
investments resulting from a decline or appreciation in the value of a
particular foreign currency against

                                      B-6
<PAGE>
 
the U.S. dollar or another foreign currency or for other reasons, the Short-
Intermediate Bond, Bond, Intermediate Bond and International Bond Portfolios are
authorized to enter into forward foreign currency exchange contracts.  These
contracts involve an obligation to purchase or sell a specified currency at a
future date at a price set at the time of the contract.  Forward currency
contracts do not eliminate fluctuations in the values of portfolio securities
but rather allow a Portfolio to establish a rate of exchange for a future point
in time.

When entering into a contract for the purchase or sale of a security, a
Portfolio may enter into a forward foreign currency exchange contract for the
amount of the purchase or sale price to protect against variations, between the
date the security is purchased or sold and the date on which payment is made or
received, in the value of the foreign currency relative to the U.S. dollar or
other foreign currency.

When Northern anticipates that a particular foreign currency may decline
substantially relative to the U.S. dollar or other leading currencies, in order
to reduce risk, a Portfolio may enter into a forward contract to sell, for a
fixed amount, the amount of foreign currency approximating the value of some or
all of the Portfolio's securities denominated in such foreign currency.
Similarly, when the obligations held by a Portfolio create a short position in a
foreign currency, the Portfolio may enter into a forward contract to buy, for a
fixed amount, an amount of foreign currency approximating the short position.
With respect to any forward foreign currency contract, it will not generally be
possible to match precisely the amount covered by that contract and the value of
the securities involved due to the changes in the values of such securities
resulting from market movements between the date the forward contract is entered
into and the date it matures.  In addition, while forward contracts may offer
protection from losses resulting from declines or appreciation in the value of a
particular foreign currency, they also limit potential gains which might result
from changes in the value of such currency.  A Portfolio may also incur costs in
connection with forward foreign currency exchange contracts and conversions of
foreign currencies and U.S. dollars.
    
In addition, with respect to the International Bond Portfolio, Northern may
purchase or sell forward foreign currency exchange contracts to seek to increase
total return.

Liquid assets equal to the amount of a Portfolio's assets that could be required
to consummate forward contracts will be segregated except to the extent the
contracts are otherwise "covered."  The segregated assets will be valued at
market or fair value.  If the market or fair value of such assets declines,
additional liquid assets will be segregated daily so that the value of the
segregated assets will equal the amount of such commitments     

                                      B-7
<PAGE>
     
by the Portfolio.  A forward contract to sell a foreign currency is "covered" if
a Portfolio owns the currency (or securities denominated in the currency)
underlying the contract, or holds a forward contract (or call option) permitting
the Portfolio to buy the same currency at a price that is (i) no higher than the
Portfolio's price to sell the currency or (ii) greater than the Portfolio's
price to sell the currency provided the Portfolio segregates liquid assets in
the amount of the difference.  A forward contract to buy a foreign currency is
"covered" if a Portfolio holds a forward contract (or call option) permitting
the Portfolio to sell the same currency at a price that is (i) as high as or
higher than the Portfolio's price to buy the currency or (ii) lower than the
Portfolio's price to buy the currency provided the Portfolio segregates liquid
assets in the amount of the difference.     

Interest Rate Swaps, Floors and Caps and Currency Swaps.  The Portfolios (other
than the U.S. Treasury Index Portfolio) may enter into interest rate swaps,
floors and caps for hedging purposes and not for speculation.  Interest rate
swaps involve the exchange by a Portfolio with another party of their respective
commitments to pay or receive interest, such as an exchange of fixed rate
payments for floating rate payments.  A Portfolio will typically use interest
rate swaps to preserve a return on a particular investment or portion of its
portfolio or to shorten the effective duration of its portfolio investments. The
purchase of an interest rate floor or cap entitles the purchaser to receive
payments of interest on a notional principal amount from the seller, to the
extent the specified index falls below (floor) or exceeds (cap) a predetermined
interest rate. The Portfolios will only enter into interest rate swaps or
interest rate floor or cap transactions on a net basis, i.e.  the two payment
streams are netted out, with a Portfolio receiving or paying, as the case may
be, only the net amount of the two payments.

The International Bond Portfolio may enter into currency swaps, which involve
the exchange of the rights of the Portfolio and another party to make or receive
payments in specified currencies.  Currency swaps usually involve the delivery
of the entire principal value of one designated currency in exchange for the
other designated currency.
    
Inasmuch as interest rate and currency swaps are entered into for good faith
hedging purposes, the Trust and Northern believe that such transactions do not
constitute senior securities as defined in the 1940 Act and, accordingly, will
not treat them as being subject to the Portfolio's borrowing restrictions. The
net amount of the excess, if any, of a Portfolio's obligations over its
entitlements with respect to interest rate or currency swaps will be accrued on
a daily basis and an amount of liquid assets having an aggregate net asset value
at least equal to such accrued excess will be segregated.     

                                      B-8
<PAGE>
 
The Portfolios will not enter into an interest rate or currency swap or interest
rate floor or cap transaction unless the unsecured commercial paper, senior debt
or the claims-paying ability of the other party thereto is rated either A or A-1
or better by S&P, Duff or Fitch, or A or P-1 or better by Moody's.  If there is
a default by the other party to such transaction, the Portfolios 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 markets for other similar instruments which
are traded in the interbank market.

Options.  Each Portfolio may buy put options and call options and write covered
call and secured put options.  Such options may relate to particular securities,
financial instruments, foreign currencies, foreign or domestic securities
indices or (in the case of the International Bond Portfolio) the yield
differential between two securities ("yield curve options") and may or may not
be listed on a domestic or foreign securities exchange (an "Exchange") or issued
by the Options Clearing Corporation.  Options trading is a highly specialized
activity which entails greater than ordinary investment risk.  Options on
particular securities may be more volatile than the underlying instruments and,
therefore, on a percentage basis, an investment in options may be subject to
greater fluctuation than an investment in the underlying instruments themselves.
    
The Portfolios will write call options only if they are "covered." In the case
of a call option on a security or currency, the option is "covered" if a
Portfolio owns the security or currency underlying the call or has an absolute
and immediate right to acquire that security or currency without additional cash
consideration (or, if additional cash consideration is required, liquid assets
in such amount are segregated) upon conversion or exchange of other securities
or instruments held by it.  For a call option on an index, the option is covered
if a Portfolio maintains with its custodian, a portfolio of securities
substantially replicating the movement of the index, or liquid assets equal to
the contract value.  A call option is also covered if a Portfolio holds a call
on the same security,  currency or index as the call written where the exercise
price of the call held is (i) equal to or less than the exercise price of the
call written, or (ii) greater than the exercise price of the call written
provided the Portfolio segregates liquid assets in the amount of the difference.
The Portfolios will write put options only if they are "secured" by segregated
liquid assets in an amount not less than the exercise price of the option at all
times during the option period.     
    
With respect to yield curve options, a call (or put) option is covered if the
International Bond Portfolio holds another call (or     

                                      B-9
<PAGE>
 
    
put) option on the spread between the same two securities and segregates liquid
assets sufficient to cover the Portfolio's net liability under the two options.
Therefore, the Portfolio's liability for such a covered option is generally
limited to the difference between the amount of the Portfolio's liability under
the option written by the Portfolio less the value of the option held by the
Portfolio.  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.     
    
A Portfolio's obligation to sell a security or currency subject to a covered
call option written by it, or to purchase a security or currency subject to a
secured put option written by it, may be terminated prior to the expiration date
of the option by the Portfolio's execution of a closing purchase transaction,
which is effected by purchasing on an exchange an option of the same series
(i.e., same underlying security or currency, exercise price and expiration date)
as the option previously written.  Such a purchase does not result in the
ownership of an option.  A closing purchase transaction will ordinarily be
effected to realize a profit on an outstanding option, to prevent an underlying
security or currency from being called, to permit the sale of the underlying
security or currency or to permit the writing of a new option containing
different terms on such underlying security.  The cost of such a liquidation
purchase plus transaction costs may be greater than the premium received upon
the original option, in which event the Portfolio will have incurred a loss in
the transaction.  There is no assurance that a liquid secondary market will
exist for any particular option.  An option writer, unable to effect a closing
purchase transaction, will not be able to sell the underlying security or
currency (in the case of a covered call option) or liquidate the segregated
assets (in the case of a secured put option) until the option expires or the
optioned security or currency is delivered upon exercise with the result that
the writer in such circumstances will be subject to the risk of market decline
or appreciation in the security or currency during such period.     

When a Portfolio purchases an option, the premium paid by it is recorded as an
asset of the Portfolio.  When the Portfolio writes an option, an amount equal to
the net premium (the premium less the commission) received by the Portfolio is
included in the liability section of the Portfolio's statement of assets and
liabilities as a deferred credit.  The amount of this asset or deferred credit
will be subsequently marked-to-market to reflect the current value of the option
purchased or written.  The current value of the traded option is the last sale
price or, in the absence of a sale, the current bid price.  If an option
purchased by the Portfolio expires unexercised the Portfolio realizes a loss
equal to the premium paid.  If the Portfolio enters into a closing sale
transaction on an option purchased by it, the Portfolio will realize a gain if
the premium received by the Portfolio on the

                                      B-10
<PAGE>
 
closing transaction is more than the premium paid to purchase the option, or a
loss if it is less.  If an option written by the Portfolio expires on the
stipulated expiration date or if the Portfolio enters into a closing purchase
transaction, it will realize a gain (or loss if the cost of a closing purchase
transaction exceeds the net premium received when the option is sold) and the
deferred credit related to such option will be eliminated.  If an option written
by the Portfolio is exercised, the proceeds of the sale will be increased by the
net premium originally received and the Portfolio will realize a gain or loss.

There are several risks associated with transactions in certain options.  For
example, there are significant differences between the securities and options
markets that could result in an imperfect correlation between these markets,
causing a given transaction not to achieve its objectives.  In addition, a
liquid secondary market for particular options, whether traded over-the-counter
or on an Exchange may be absent for reasons which include the following: there
may be insufficient trading interest in certain options; restrictions may be
imposed by an Exchange on opening transactions or closing transactions or both;
trading halts, suspensions or other restrictions may be imposed with respect to
particular classes or series of options or underlying securities or currencies;
unusual or unforeseen circumstances may interrupt normal operations on an
Exchange; the facilities of an Exchange or the Options Clearing Corporation may
not at all times be adequate to handle current trading value; or 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 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.

Futures Contracts and Related Options.  Each Portfolio may invest in futures
contracts and interest rate futures contracts and may purchase and sell call and
put options on futures contracts for hedging purposes, for speculative purposes
(to seek to increase total return), or for liquidity management purposes. For a
detailed description of futures contracts and related options, see Appendix B to
this Additional Statement.

Securities Lending.  Collateral for loans of portfolio securities made by a
Portfolio may consist of cash, securities issued or guaranteed by the U.S.
Government or its agencies or irrevocable bank letters of credit (or any
combination thereof).  The borrower of securities will be required to maintain
the market value of the collateral at not less than the market value of the
loaned securities, and such value will be monitored on a daily basis.  When a
Portfolio lends its securities, it continues to receive

                                      B-11
<PAGE>
 
dividends and/or interest on the securities loaned and may simultaneously earn
interest on the investment of the cash collateral which will be invested in
readily marketable, high quality, short-term obligations.  Although voting
rights, or rights to consent, attendant to securities on loan pass to the
borrower, such loans will be called so that the securities may be voted by a
Portfolio if a material event affecting the investment is to occur.
    
Forward Commitments, When-Issued Securities and Delayed Delivery Transactions.
When a Portfolio purchases securities on a when-issued, delayed delivery or
forward commitment basis, the Portfolio will segregate liquid assets having a
value (determined daily) at least equal to the amount of the Portfolio's
purchase commitments.  In the case of a forward commitment to sell portfolio
securities, the Portfolio will segregate the portfolio securities themselves.
These procedures are designed to ensure that the Portfolio will maintain
sufficient assets at all times to cover its obligations under when-issued
purchases, forward commitments and delayed delivery transactions.  For purposes
of determining a Portfolio's average dollar-weighted maturity, the maturity of
when-issued or forward commitment securities will be calculated from the
commitment date.     

Commercial Paper, Bankers' Acceptances, Certificates of Deposit, Time Deposits
and Bank Notes.  Commercial paper represents short-term unsecured promissory
notes issued in bearer form by banks or bank holding companies, corporations and
finance companies.  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 that
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.  Bank notes rank
junior to deposit liabilities of banks and pari passu with other senior,
unsecured obligations of the bank. Some states have "depositor preference" laws
that give depositors of their state chartered banks priority over holders of
bank notes and other general creditors. In addition, the U.S. Congress has
adopted legislation which creates a Federal "depositor preference" law providing
the claims of certain creditors of an insured depository institution (including
its depositors) with priority over the claims of that institution's unsecured
creditors (including holders of its notes), in the event of that institution's
insolvency or other resolution. Bank notes are classified as "other borrowings"

                                      B-12
<PAGE>
 
on a bank's balance sheet, while deposit notes and certificates of deposit are
classified as deposits. 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 to the extent of $100,000 per depositor.

A Portfolio may invest a portion of its assets in the obligations of foreign
banks and foreign branches of domestic banks.  Such obligations include
Eurodollar Certificates of Deposit ("ECDs") which are U.S. dollar-denominated
certificates of deposit issued by offices of foreign and domestic banks located
outside the United States; Eurodollar Time Deposits ("ETDs") which are U.S.
dollar-denominated deposits in a foreign branch of a U.S. bank or a foreign
bank; Canadian Time Deposits ("CTDs") which are essentially the same as ETDs
except they are issued by Canadian offices of major Canadian banks; Schedule Bs,
which are obligations issued by Canadian branches of foreign or domestic banks;
Yankee Certificates of Deposit ("Yankee CDs") which are U.S. dollar-denominated
certificates of deposit issued by a U.S. branch of a foreign bank and held in
the United States; and Yankee Bankers' Acceptances ("Yankee BAs") which are U.S.
dollar-denominated bankers' acceptances issued by a U.S. branch of a foreign
bank and held in the United States.

Variable and Floating Rate Instruments.  With respect to variable and floating
rate instruments that may be acquired by the Portfolios, The Northern Trust
Company ("Northern") and Northern Trust Quantitative Advisors, Inc. ("NTQA" and,
collectively with Northern, the "Investment Advisers") will consider the earning
power, cash flows and other liquidity ratios of the issuers and guarantors of
such instruments and, if the instruments are subject to demand features, will
continuously monitor their financial status and ability to meet payment on
demand.  Where necessary to ensure that a variable or floating rate instrument
meets the Portfolios' quality requirements, the issuer's obligation to pay the
principal of the instrument will be backed by an unconditional bank letter or
line of credit, guarantee or commitment to lend.
    
Investment Companies.  With respect to the investments of the Portfolios in the
securities of other investment companies, such investments will be limited so
that, as determined after a purchase is made, either (a) not more than 3% of the
total outstanding stock of such investment company will be owned by a Portfolio,
the Trust as a whole and their affiliated persons (as defined in the 1940 Act);
or (b)(i) not more than 5% of the value of the total assets of a Portfolio will
be invested in the securities of any one investment company, (ii) not more than
10% of the value of its total assets will be invested in the aggregate in
securities of investment companies as a group, and (iii) not more than 3% of the
outstanding voting stock of any one investment company will be owned by the
Portfolio.  Certain investment companies whose securities are purchased by the
Portfolios may not be obligated to     

                                      B-13
<PAGE>
 
    
redeem such securities in an amount exceeding 1% of the investment company's
total outstanding securities during any period of less than 30 days.  Therefore,
such securities that exceed this amount may be illiquid.     
    
If required by the 1940 Act, each Portfolio expects to vote the shares of other
investment companies that are held by it in the same proportion as the vote of
all other holders of such securities.  A Portfolio may invest all or
substantially all of its assets in a single open-end investment company or
series thereof with substantially the same investment objective, policies and
restrictions as the Portfolio.  However, each Portfolio currently intends to
limit its investments in securities issued by other investment companies to the
extent described above.  A Portfolio may adhere to more restrictive limitations
with respect to its investments in securities issued by other investment
companies if required by the SEC or deemed to be in the best interests of the
Trust.     

Repurchase Agreements.  Each Portfolio may enter into repurchase agreements with
financial institutions, such as banks and broker-dealers, as are deemed
creditworthy by the Investment Advisers under guidelines approved by the Trust's
Board of Trustees.  The repurchase price under the repurchase agreements will
generally equal the price paid by a Portfolio plus interest negotiated on the
basis of current short-term rates (which may be more or less than the rate on
the securities underlying the repurchase agreement).  Securities subject to
repurchase agreements will be held by the Trust's custodian (or subcustodian),
in the Federal Reserve/Treasury book-entry system or by another authorized
securities depository.  Repurchase agreements are considered to be loans by a
Portfolio under the 1940 Act.
    
Reverse Repurchase Agreements.  Each Portfolio may borrow funds for temporary or
emergency purposes by selling portfolio securities to financial institutions
such as banks and broker/dealers and agreeing to repurchase them at a mutually
specified date and price ("reverse repurchase agreements").  Reverse repurchase
agreements involve the risk that the market value of the securities sold by a
Portfolio may decline below the repurchase price.  The Portfolios will pay
interest on amounts obtained pursuant to a reverse repurchase agreement.  While
reverse repurchase agreements are outstanding, a Portfolio will segregate liquid
assets in an amount at least equal to the market value of the securities, plus
accrued interest, subject to the agreement.  Reverse repurchase agreements are
considered to be borrowings by a Portfolio under the 1940 Act.     

Risks Related to Lower-Rated Securities.  While any investment carries some
risk, certain risks associated with lower-rated securities are different than
those for investment-grade securities.  The risk of loss through default is
greater because lower-rated securities are usually unsecured and are often

                                      B-14
<PAGE>
 
subordinate to an issuer's other obligations.  Additionally, the issuers of
these securities frequently have high debt levels and are thus more sensitive to
difficult economic conditions, individual corporate developments and rising
interest rates.  Consequently, the market price of these securities may be quite
volatile and may result in wider fluctuations of a Portfolio's net asset value
per share.

There remains some uncertainty about the performance level of the market for
lower-rated securities under adverse market and economic environments.  An
economic downturn or increase in interest rates could have a negative impact on
both the markets for lower-rated securities (resulting in a greater number of
bond defaults) and the value of lower-rated securities held in a portfolio of
investments.

The economy and interest rates can affect lower-rated securities differently
than other securities.  For example, the prices of lower-rated securities are
more sensitive to adverse economic changes or individual corporate developments
than are the prices of higher-rated investments.  In addition, during an
economic downturn or period in which interest rates are rising significantly,
highly leveraged issuers may experience financial difficulties, which, in turn,
would adversely affect their ability to service their principal and interest
payment obligations, meet projected business goals and obtain additional
financing.

If an issuer of a security defaults, a Portfolio may incur additional expenses
to seek recovery.  In addition, periods of economic uncertainty would likely
result in increased volatility for the market prices of lower-rated securities
as well as a Portfolio's net asset value.  In general, both the prices and
yields of lower-rated securities will fluctuate.

In certain circumstances it may be difficult to determine a security's fair
value due to a lack of reliable objective information.  Such instances occur
where there is not an established secondary market for the security or the
security is lightly traded.  As a result, a Portfolio's valuation of a security
and the price it is actually able to obtain when it sells the security could
differ.

Adverse publicity and investor perceptions, whether or not based on fundamental
analysis, may decrease the value and liquidity of lower-rated securities held by
a Portfolio, especially in a thinly traded market.  Illiquid or restricted
securities held by the Portfolio may involve special registration
responsibilities, liabilities and costs, and could involve other liquidity and
valuation difficulties.

The rating assigned by a rating agency evaluates the safety of a lower-rated
security's principal and interest payments, but does not address market value
risk.  Because the ratings of the rating

                                      B-15
<PAGE>
 
agencies may not always reflect current conditions and events, in addition to
using recognized rating agencies and other sources, the Investment Advisers
perform their own analysis of the issuers whose lower-rated securities the
Portfolios hold.  Because of this, the Portfolios' performance may depend more
on their own credit analysis than in the case of mutual funds investing in
higher-rated securities.
    
In selecting lower-rated securities, the Investment Advisers consider factors
such as those relating to the creditworthiness of issuers, the ratings and
performance of the securities, the protections afforded the securities and the
diversity of a Portfolio's investment portfolio.  The Investment Advisers
continuously monitor the issuers of lower-rated securities held by a Portfolio
for their ability to make required principal and interest payments, as well as
in an effort to control the liquidity of the Portfolio so that it can meet
redemption requests.     

Yields and Ratings.  The yields on certain obligations, including the
instruments in which the Portfolios may invest, are dependent on a variety of
factors, including general market conditions, conditions in the particular
market for the obligation, financial condition of the issuer, size of the
offering, maturity of the obligation and ratings of the issue.  The ratings of
S&P, Moody's, Duff, Fitch and TBW represent their respective opinions as to the
quality of the obligations they undertake to rate.  Ratings, however, are
general and are not absolute standards of quality.  Consequently, obligations
with the same rating, maturity and interest rate may have different market
prices.

Subject to the limitations stated in the Prospectus, if a Portfolio security
undergoes a rating revision, a Portfolio may continue to hold the security if
the Investment Adviser determines that retention is warranted.

Calculation of Portfolio Turnover Rate.  The portfolio turnover rate for the
Portfolios is calculated by dividing the lesser of purchases or sales of
portfolio investments for the reporting period by the monthly average value of
the portfolio investments owned during the reporting period.  The calculation
excludes all securities, including options, whose maturities or expiration dates
at the time of acquisition are one year or less.  Portfolio turnover may vary
greatly from year to year as well as within a particular year, and may be
affected by cash requirements for redemption of shares and by requirements which
enable the Portfolios to receive favorable tax treatment.

Investment Restrictions Applicable to the U.S. Government Securities, Short-
Intermediate Bond, U.S. Treasury Index, Bond, Intermediate Bond and
International Bond Portfolios

                                      B-16
<PAGE>
 
The U.S. Government Securities, Short-Intermediate Bond, U.S. Treasury Index,
Bond, Intermediate Bond and International Bond Portfolios are subject to the
fundamental investment restrictions enumerated below which may be changed with
respect to these particular Portfolios only by a vote of the holders of a
majority of a Portfolio's outstanding shares.

No Portfolio may:

     (1) Make loans, except (a) through the purchase of debt obligations in
accordance with the Portfolio's investment objective and policies, (b) through
repurchase agreements with banks, brokers, dealers and other financial
institutions, and (c) loans of securities.

     (2) Mortgage, pledge or hypothecate any assets (other than pursuant to
reverse repurchase agreements) except to secure permitted borrowings.

     (3) Purchase or sell real estate, but this restriction shall not prevent a
Portfolio from investing directly or indirectly in portfolio instruments secured
by real estate or interests therein or acquiring securities of real estate
investment trusts or other issuers that deal in real estate.

     (4) Purchase or sell commodities or commodity contracts or oil or gas or
other mineral exploration or development programs, except that each Portfolio
may, to the extent appropriate to its investment policies, purchase securities
of companies engaging in whole or in part in such activities, enter into futures
contracts and related options, and enter into forward currency contracts in
accordance with its investment objective and policies.

     (5) Invest in companies for the purpose of exercising control.

     (6) Act as underwriter of securities, except as a Portfolio may be deemed
to be an underwriter under the Securities Act of 1933 in connection with the
purchase and sale of portfolio instruments in accordance with its investment
objective and portfolio management policies.

     (7) Write puts, calls or combinations thereof, except for transactions in
options on securities, financial instruments, currencies and indices of
securities (and in the case of the International Bond Portfolio, yield curve
options); futures contracts; options on futures contracts; forward currency
contracts; short sales of securities against the box; interest rate swaps (and
in the case of the International Bond Portfolio, currency swaps); and pair-off
transactions (except in the case of the International Bond Portfolio).

                                      B-17
<PAGE>


   
     (8) Purchase securities (other than obligations issued or guaranteed by the
U.S. Government, its agencies or instrumentalities) if such purchase would cause
more than 25% in the aggregate of the market value of the total assets of a
Portfolio to be invested in the securities of one or more issuers having their
principal business activities in the same industry.      



                                       

                                      B-18
<PAGE>
 
    
For the purposes of this restriction, as to utility companies, the gas, 
electric, water and telephone businesses are considered separate industries;
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 industries of their parents if their activities are
primarily related to financing the activities of their parents.    

     (9) Borrow money (other than pursuant to reverse repurchase agreements),
except (a) as a temporary measure, and then only in amounts not exceeding 5% of
the value of the Portfolio's total assets or (b) from banks, provided that
immediately after any such borrowing all borrowings of the Portfolio do not
exceed one-third of the Portfolio's total assets.  No purchases of securities
will be made if borrowings subject to this restriction exceed 5% of the value of
the Portfolio's assets.  The exceptions in (a) and (b) to this restriction are
not for investment leverage purposes but are solely for extraordinary or
emergency purposes or to facilitate management of the Portfolios by enabling the
Trust to meet redemption requests when the liquidation of Portfolio instruments
is deemed to be disadvantageous or not possible.  If due to market fluctuations
or other reasons the total assets of a Portfolio fall below 300% of its
borrowings, the Trust will promptly reduce the borrowings of such Portfolio in
accordance with the 1940 Act.

     (10) Notwithstanding any of the Trust's other fundamental investment
restrictions (including, without limitation, those restrictions relating to
issuer diversification, industry concentration and control), each Portfolio may
(a) purchase securities of other investment companies to the full extent
permitted under Section 12 of the 1940 Act (or any successor provision thereto)
or under any regulation or order of the Securities and Exchange Commission; and
(b) invest all or substantially all of its assets in a single open-end
investment company or series thereof with substantially the same investment
objective, policies and fundamental restrictions as the Portfolio.

In addition, with respect to the U.S. Government Securities, Short-Intermediate,
U.S. Treasury Index, Bond and Intermediate Bond Portfolios:

     (11) The Portfolio may not make any investment inconsistent with the
Portfolio's classification as a diversified investment company under the 1940
Act, provided that this restriction does not apply to the International Bond
Portfolio.

                                      B-19
<PAGE>
 
    
In applying the restriction No. 8 above, a security is considered to be issued
by the entity, or entities, whose assets and revenues back the security.  A
guarantee of a security is not deemed to be a security issued by the guarantor
when the value of all securities issued and guaranteed by the guarantor, and
owned by the Portfolio, does not exceed 10% of the value of the Portfolio's
total assets.     
    
Except to the extent otherwise provided in Investment Restriction No. 8 for the
purpose of such restriction, in determining industry classification the Trust
intends to use the industry classification titles in the Standard Industrial
Classification Manual (except that the International Bond Portfolio will use the
Morgan Stanley Capital International industry classification titles).
Securities held in escrow or separate accounts in connection with a Portfolio's
investment practices described in this Additional Statement and in the
Prospectus are not deemed to be mortgaged, pledged or hypothecated for purposes
of the foregoing Investment Restrictions.     

In addition, as a matter of fundamental policy, the International Bond Portfolio
will not issue senior securities except as stated in the Prospectus or this
Additional Statement.

As a non-fundamental investment restriction, the International Bond Portfolio
may not, at the end of any tax quarter, hold more than 10% of the outstanding
voting securities of any one issuer, except that up to 50% of the total value of
the assets of the Portfolio may be invested in any securities without regard to
this 10% limitation so long as no more than 25% of the total value of its assets
is invested in the securities of any one issuer (except the U.S. Government).
As a non-fundamental investment restriction that can be changed without
shareholder approval, the International Bond Portfolio may not, at the end of
any tax quarter, invest more than 5% of the total value of its assets in the
securities of any one issuer (except U.S. Government securities), except that up
to 50% of the total value of the Portfolio's assets may be invested in any
securities without regard to this 5% limitation so long as no more than 25% of
the total value of its assets is invested in the securities of any one issuer
(except U.S. Government securities).

Any restriction which involves a maximum percentage will 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.

Certain of the Trustees and officers and the organizations with which they are
associated have had in the past, and may have in the future, transactions with
the Investment Advisers, Goldman Sachs and their respective affiliates.  The
Trust has been advised by such Trustees and officers that all such transactions
have been and are expected to be in the ordinary course of business and the
terms of such transactions, including all loans and loan commitments by such
persons, have been and are expected to be substantially the same as the
prevailing terms for comparable transactions for other customers.  Messrs.
Springer, Kelsey, Strubel, Mosior, Gilman, Richman, Surloff and Hartstein and
Mmes. Farrell, Mucker, and Zondorak hold similar positions with one or more
investment companies that are advised by Goldman Sachs.  As a result of the
responsibilities assumed by the Investment Advisers under the Advisory
Agreement, Transfer Agency Agreements with the Trust, by Northern under its
Custodian Agreement and Foreign Custody Agreement with the Trust and by Goldman
Sachs under its Administration Agreement and Distribution Agreement with the
Trust, the Trust itself requires no employees.     

Each officer holds comparable positions with certain other investment companies
of which Goldman Sachs, GSAM or an affiliate thereof is the investment adviser,
administrator and/or distribu tor.

Each Trustee earns a quarterly retainer of $6,250 and the Chairman of the Board
earns a quarterly retainer of $9,375.  Each Trustee, including the Chairman of
the Board, earns an additional fee of $1,500 for each meeting attended, plus
reimbursement of expenses incurred as a Trustee.

In addition, the Trustees established an Audit Committee consisting of three
members including a Chairman of the Committee.  Each member earns a fee of
$1,500 for each meeting attended and the Chairman earns a quarterly retainer of
$1,250.

Each Trustee will hold office for an indefinite term until the earliest of (1)
the next meeting of shareholders if any, called for the purpose of considering
the election or re-election of such Trustee and until the election and
qualification of his or her successor, if any, elected at such meeting; (2) the
date a Trustee resigns or retires, or a Trustee is removed by the Board of
Trustees or shareholders, in accordance with the Trust's Agreement and
Declaration of Trust; or (3) in accordance with the current resolutions of the
Board of Trustees (which may be changed without shareholder vote), on the last
day of the fiscal year of the Trust in which he or she attains the age of 72
years.

The Trust's officers do not receive fees from the Trust for services in such
capacities, although Goldman Sachs, of which they are also officers, receives
fees from the Trust for administrative services.

products and services is to achieve unrivaled client satisfaction. With respect
to such clients, the Trust is designed to assist (i) defined contribution plan
sponsors and their employees by offering a range of diverse investment options
to help comply with 404(c) regulation and may also provide educational material
to their employees, (ii) employers who provide post-retirement Employees'
Beneficiary Associations ("VEBA") and require investments that respond to the
impact of federal regulations, (iii) insurance companies with the day-to-day
management of uninvested cash balances as well as with longer-term investment
needs, and (iv) charitable and not-for-profit organizations, such as endowments
and foundations, demanding investment management solutions that balance the
requirement for sufficient current income to meet operating expenses and the
need for capital appreciation to meet future investment objectives.  NTQA, also
a wholly-owned subsidiary of Northern Trust Corporation, serves as investment
adviser principally to defined benefit and defined contribution plans and
manages over 60 equity and bond commingled and common trust funds.  As of
December 31, 1997, the Investment Advisers and their affiliates had
approximately $196 billion in assets under management for clients including
public and private retirement funds, endowments, foundations, trusts,
corporations other investment companies and individuals.
    
Subject to the general supervision of the Board of Trustees, the Investment
Advisers make decisions with respect to and places orders for all purchases and
sales of portfolio securities for each Portfolio.  The Advisory Agreements with
the Trust provide that in selecting brokers or dealers to place orders for
transactions the Investment Advisers shall attempt to obtain best net price and
execution or, with respect to the International Bond and Intermediate Bond
Portfolios, their best judgment to obtain the best overall terms available.  In
assessing the best overall terms available for any transaction, the Investment
Advisers are to consider all factors they deem relevant, including the breadth
of the market in the security, the price of the security, the financial
condition and execution capability of the broker or dealer, and the
reasonableness of the commission, if any, both for the specific transaction and
on a continuing basis. In evaluating the best overall terms available and in
selecting the broker or dealer to execute a particular transaction, the
Investment Advisers may consider the brokerage and research services provided to
the Portfolios and/or other accounts over which the Investment Advisers or an
affiliate of Northern exercise investment discretion.  These     

                                      B-28
<PAGE>
 
    
brokerage and research services may include industry and company analyses,
portfolio services, quantitative data, market information systems and economic
and political consulting and analytical services.     
    
Transactions on U.S. stock exchanges involve the payment of negotiated brokerage
commissions.  On exchanges on which commissions are negotiated, the cost of
transactions may vary among different brokers.  Transactions on foreign
securities exchanges involve payment for brokerage commissions which are
generally fixed.  Over-the-counter issues, including corporate debt and
government securities, are normally traded on a "net" basis (i.e., without
commission) through dealers, or otherwise involve transactions directly with the
issuer of an instrument.  With respect to over-the-counter transactions, the
Investment Advisers will normally deal directly with dealers who make a market
in the instruments involved except in those circumstances where more favorable
prices and execution are available elsewhere.  The cost of foreign and domestic
securities purchased from underwriters includes an underwriting commission or
concession, and the prices at which securities are purchased from and sold to
dealers include a dealer's mark-up or mark-down.     

The Portfolios may participate, if and when practicable, in bidding for the
purchase of portfolio securities directly from an issuer in order to take
advantage of the lower purchase price available to members of a bidding group.
The Portfolios will engage in this practice, however, only when the Investment
Advisers believe such practice to be in the Portfolios' interests.

On occasions when the Investment Advisers deem the purchase or sale of a
security to be in the best interests of a Portfolio as well as other fiduciary
or agency accounts managed by them (including any other Portfolio, investment
company or account for which the Investment Advisers act as adviser), the
Agreements provide that the Investment Adviser, to the extent permitted by
applicable laws and regulations, may aggregate the securities to be sold or
purchased for such Portfolio with those to be sold or purchased for such other
accounts in order to obtain the best net price and execution.  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 Investment Advisers in the
manner they consider to be most equitable and consistent with their fiduciary
obligations to the Portfolio and other accounts involved.  In some instances,
this procedure may adversely affect the size of the position obtainable for a
Portfolio or the amount of the securities that are able to be sold for a
Portfolio.  To the extent that the execution and price available from more than
one broker or dealer are believed to be comparable, the Agreements permit the
Investment Advisers, at their discretion but subject to applicable law, to
select the executing broker or dealer on the basis of their opinion of the
reliability and quality of such broker or dealer.

The Advisory Agreements provide that the Investment Advisers may render
similar services to others so long as its services under such Agreements are not
impaired thereby.  The Advisory Agreements also provide that the Trust will
indemnify the Investment Advisers against certain liabilities (including
liabilities under the Federal securities laws relating to untrue statements or
omissions of material fact and actions that are in accordance with the terms of
the Agreement) or, in lieu thereof, contribute to resulting losses.

by Institutions, Northern has undertaken to perform some or all of the following
services: (1) establish and maintain an omnibus account in the name of each

furnish necessary office space, facilities and personnel.  Under the Transfer
Agency Agreement, with respect to shares held by investors, Northern has also
undertaken to perform some or all of the following services: (1) establish and
maintain separate accounts in the name of the investors; (2) process purchase
orders and redemption requests, and furnish confirmations in accordance with
applicable law; (3) disburse redemption proceeds; (4) process and record the

investors and respond to all requests for information regarding the Trust (such
as current price, recent performance, and yield data) and questions relating to
accounts of investors (such as possible errors in statements, and transactions);
(8) respond to and seek to resolve all complaints of investors with respect to
the Trust or their accounts; (9) furnish proxy statements and proxies, annual
and semi-annual financial statements, and dividend, distribution and tax notices
to investors; (10) furnish the Trust all pertinent Blue Sky information; (11)

                                      B-30

As compensation for the services rendered by Northern under the Transfer Agency
Agreement and the assumption by Northern of related expenses, Northern is
entitled to a fee from the Trust, payable monthly, at an annual rate of .01%,
 .05%, .10% and .15% of the average daily net asset value of the Class A, B, C
and D Shares, respectively, in the Portfolios.
    
Under its Custodian Agreement (and in the case of the International Bond
Portfolio its Foreign Custody Agreement) with the Trust, Northern (1) holds each
Portfolio's cash and securities, (2) maintains such cash and securities in
separate accounts in the name of the Portfolio, (3) makes receipts and
disbursements of funds on behalf of the Portfolio, (4) receives, delivers and
releases securities on behalf of the Portfolio, (5) collects and receives all
income, principal and other payments in respect of the Portfolio's investments
held by Northern under the Agreement, and (6) maintains the accounting records
of the Trust. Northern may employ one or more subcustodians, provided that
Northern, subject to certain monitoring responsibilities, shall have no more
responsibility or liability to the Trust on account of any action or omission of
any subcustodian so employed than such subcustodian has to Northern and that the
responsibility or liability of the subcustodian to Northern shall conform to the
resolution of the Trustees of the Trust authorizing the appointment of the
particular subcustodian (or, in the case of foreign securities, to the terms of
any agreement entered into between Northern and such subcustodian to which such
resolution relates).  In addition, the Trust's custodial arrangements provide,
with respect to foreign securities, that Northern shall not be:  (i) responsible
for the solvency of any subcustodian appointed by it with reasonable care; (ii)
responsible for any act, omission, default or for the solvency of any eligible
foreign securities depository; or (iii) liable for any loss, damage, cost,
expense, liability or claim resulting from nationalization, expropriation,
currency restrictions, or acts of war or terrorism or any loss where the
subcustodian has otherwise exercised reasonable care. Northern may also appoint
agents to carry out such of the provisions of the Custodian Agreement and the
Foreign Custody Agreement as Northern may from time to time direct, provided
that the appointment of an agent shall not relieve Northern of any of its
responsibilities under either Agreement. Northern has entered into agreements
with financial institutions and depositories located in foreign countries with
respect to the custody of the Portfolios' foreign securities.     

As compensation for the services rendered to the Trust by Northern as custodian
to the U.S. Government Securities, Short-Intermediate Bond, U.S. Treasury Index,
Bond  and Intermediate Bond Portfolios, and the assumption by Northern of
certain related expenses, Northern is entitled to payment from the Trust as
follows: (i) $18,000 annually for each Portfolio, plus (ii) 1/100th of 1%
annually of each Portfolio's average daily net assets to the extent they exceed
$100 million, plus (iii) a fixed dollar fee for each

                                      B-31
<PAGE>
 
trade in portfolio securities, plus (iv) a fixed dollar fee for each time that
Northern as Custodian receives or transmits funds via wire, plus (v)
reimbursement of expenses incurred by Northern as custodian for telephone,
postage, courier fees, office supplies and duplicating.  The fees referred to in
clauses (iii) and (iv) are subject to annual upward adjustments based on
increases in the Consumer Price Index for All Urban Consumers, provided that
Northern may permanently or temporarily waive all or any portion of any upward
adjustment.

As compensation for the services rendered to the Trust under the Foreign Custody
Agreement with respect to the International Bond Portfolio, and the assumption
by Northern of certain related expenses, Northern is entitled to payment from
the Trust as follows:  (i) $35,000 annually for the International Bond
Portfolio, plus (ii) 9/100th of 1% annually of the Portfolio's average daily net
assets, plus (iii) reimbursement for fees incurred by Northern as foreign
Custodian for telephone, postage, courier fees, office supplies and duplicating.

Northern's fees under the Custodian Agreement and Foreign Custody Agreement are
subject to reduction based on the Portfolios' daily uninvested cash balances (if
any).
         
Unless sooner terminated, the Advisory Agreements, the Custodian Agreement (or
in the case of the International Bond Portfolio the Foreign Custody Agreement)
and the Transfer Agency Agreement  will continue in effect with respect to a
particular Portfolio until April 30, 1999 and thereafter for successive 12-month
periods, provided that the continuance is approved at least annually (1) by the
vote of a majority of the Trustees who are not parties to the agreement or
"interested persons" (as such term is defined in the 1940 Act) of any party
thereto, cast in person at a meeting called for the purpose of voting on such
approval and (2) by the Trustees or by the vote of a majority of the outstanding
shares of such Portfolio (as defined below under "Other Information").  Each
agreement is terminable at any time without penalty by the Trust (by specified
Trustee or shareholder action) on 60 days' written notice to Northern or NTQA
and by Northern or NTQA on 60 days' written notice to the Trust.

Prior to April 1, 1998, Northern served as investment adviser to the U.S.
Treasury Index Portfolio on the same terms as those described above.  For the
fiscal periods ended November 30 as indicated, the amount of the Advisory Fee
incurred by each Portfolio (after fee waivers) was as follows:

Banking laws and regulations currently prohibit a bank holding company
registered under the Federal Bank Holding Company Act of 1956 or any bank or
non-bank affiliate thereof from sponsoring, organizing, controlling or
distributing the shares of a registered open-end investment company continuously
engaged in the issuance of its shares, but such banking laws and regulations do
not prohibit such a holding company or affiliate or banks generally from acting
as investment adviser, transfer agent or custodian to such an investment
company, or from purchasing shares of such a company as agent for and upon the
order of customers.  Northern and NTQA believe that they may perform the
services contemplated by their agreements with the Trust without violation of
such banking laws or regulations, which are applicable to them.  It should be
noted, however, that future changes in either Federal or state statutes and
regulations relating to the permissible activities of banks and

                                      B-34
<PAGE>
 
their subsidiaries or affiliates, as well as future judicial or administrative
decisions or interpretations of current and future statutes and regulations,
could prevent Northern and NTQA from continuing to perform such services for the
Trust.

Should future legislative, judicial or administrative action prohibit or
restrict the activities of Northern and NTQA in connection with the provision of
services on behalf of the Trust, the Trust might be required to alter materially
or discontinue its arrangements with Northern and NTQA and change its method of
operations.  It is not anticipated, however, that any change in the Trust's
method of operations would affect the net asset value per share of any Portfolio
or result in a financial loss to any shareholder.  Moreover, if current
restrictions preventing a bank from legally sponsoring, organizing, controlling
or distributing shares of an open-end investment company were relaxed, the Trust
expects that Northern and its affiliates would consider the possibility of
offering to perform some or all of the services now provided by Goldman Sachs.
It is not possible, of course, to predict whether or in what form such
restrictions might be relaxed or the terms upon which Northern and its
affiliates might offer to provide services for consideration by the Trustees.

Goldman Sachs is also an active investor, dealer and/or underwriter in many
types of stocks, bonds and other instruments. Its activities in this regard
could have some effect on the market for those instruments which the Portfolios
acquire, hold or sell.

In the Advisory Agreements, the Investment Advisers agree that the name "The
Benchmark" may be used in connection with the Trust's business on a royalty-free
basis.  Northern has reserved to itself the right to grant the non-exclusive
right to use the name "The Benchmark" to any other person.  The Advisory
Agreements provide that at such time as the Agreements are no longer in effect,
the Trust will cease using the name "The Benchmark." (This undertaking by the
Trust may be subject to certain legal limitations.)

Portfolio Transactions
    
To the extent that a Portfolio effects brokerage transactions with Goldman Sachs
or any broker-dealer affiliated directly or indirectly with the Investment
Advisers, such transactions, including the frequency thereof, the receipt of any
commissions payable in connection therewith, and the selection of the affiliated
broker-dealer effecting such transactions, will be fair and reasonable to the
shareholders of the Portfolio.  For the past three fiscal years, none of the
Portfolios paid brokerage commissions.

During the fiscal year ended November 30, 1997, the Short-Intermediate Bond
Portfolio acquired and sold securities of Societe Generale Securities
Corporation, Banque Paribas and Donaldson, Lufkin & Jenrette Securities, Inc.,
each a regular broker/dealer.

At November 30, 1997, the Short-Intermediate Bond Portfolio owned the following
amounts of securities of its regular broker/dealers, as defined in Rule 10b-1
under the 1940 Act, or their parents:  Salomon Brothers, Inc., with an
approximate aggregate value of $4,993,000; and Donaldson, Lufkin & Jenrette
Securities, Inc., with an approximate aggregate market value of $2,865,000.

During the fiscal year ended November 30, 1997, the Bond Portfolio acquired and
sold securities of Donaldson, Lufkin & Jenrette Securities, Inc., a regular
broker/dealer. At November 30, 1997, the Bond Portfolio owned the following
amounts of securities of its regular broker/dealers, as defined in Rule 10b-1
under the 1940 Act, or their parents:  Donaldson, Lufkin & Jenrette Securities,
Inc., with an approximate aggregate market value of $5,256,000.

During the fiscal year ended November 30, 1997, the Intermediate Bond Portfolio
acquired and sold securities of Societe Generale Securities Corporation a
regular broker/dealer.  During the fiscal year ended November 30, 1997 the
International Bond Portfolio acquired and sold securities of Banque Brussels
Lambert, Banque Paribas and Societe Generale Securities Corporation, each a
regular broker/dealer.     

Administrator and Distributor

Under its Administration Agreement with the Trust, Goldman Sachs, subject to the
general supervision of the Trust's Board of Trustees, acts as the Trust's
Administrator.  In this capacity, Goldman Sachs (1) provides supervision of
certain aspects of the Trust's non-investment advisory operations (the parties
giving recognition to the fact that certain of such operations are performed by
Northern pursuant to the Trust's agreements with Northern), (2) provides the
Trust, to the extent not provided pursuant to such agreements, with such
personnel as are reasonably necessary for the conduct of the Trust's affairs,
(3) arranges, to the extent not provided pursuant to such agreements, for the
preparation at the Trust's expense of its tax returns, reports to shareholders,
periodic updating of the prospectuses issued by the Trust, and reports filed
with the SEC and other regulatory authorities (including qualification under
state securities or Blue Sky laws of the Trust's shares), and (4) provides the
Trust, to the extent not provided pursuant to such agreements, with adequate
office space and equipment and certain related services in Chicago.

For the fiscal periods ended November 30 as indicated, Goldman Sachs received
fees under the Administration Agreement (after fee waivers) in the amount of:

For the fiscal periods ended November 30 as indicated and prior to May 1, 1997,
Goldman Sachs voluntarily agreed to waive a portion of its Administration Fee
for each Portfolio then in existence resulting in an effective fee of .10% of
the average daily net assets for each Portfolio. The effect of these waivers by
Goldman Sachs was to reduce Administration Fees by the following amounts:

In addition, pursuant to an undertaking that commenced August 1, 1992, Goldman
Sachs agreed that, if its administration fees (less expense reimbursements paid
by Goldman Sachs to the Trust and less certain marketing expenses paid by
Goldman Sachs) exceed a specified amount ($1 million for the Trust's first
twelve invest ment portfolios plus $50,000 for each additional portfolio) during
the current fiscal year, Goldman Sachs will waive a portion of its
administration fees during the following fiscal year.  This undertaking may be
terminated by Goldman Sachs at any time without the consent of the Trust or the
shareholders. There have been no waivers pursuant to this agreement during the
last three fiscal periods.

Goldman Sachs has agreed for the current fiscal year to reimburse each
Portfolio for all expenses (including fees payable to Goldman Sachs as
administrator, but excluding advisory fees, transfer agent fees, servicing fees
and extraordinary expenses) which exceed on an annualized basis .25% of the
International Bond Portfolio's average daily net assets and .10% of each other
Portfolio's average daily net assets.  Prior to May 1, 1997, this undertaking
was voluntary with respect to the Portfolios. As of May 1, 1997, this
undertaking is contractual with respect to all Portfolios.  The effect of these
reimbursements by Goldman Sachs for the fiscal periods ended November 30 as
indicated, were to reduce the expenses of each Portfolio by:

Unless sooner terminated, the Administration Agreement will continue in effect
with respect to a particular Portfolio until April 30, 1999, and thereafter for
successive 12-month periods, provided that the agreement is approved annually
(1) by the vote of a majority of the Trustees who are not parties to the
agreement or "interested persons" (as such term is defined by the 1940 Act) of
any party thereto, cast in person at a meeting called for the purpose of voting
on such approval, and (2) by the Trustees or by the vote of a majority of the
outstanding shares of such Portfolio (as defined below under "Other
Information"). The Administration Agreement is terminable at any time without
penalty by the Trust (upon specified Trustee or shareholder action) on 60 days'
written notice to Goldman Sachs and by Goldman Sachs on 60 days' written notice
to the Trust. The Trust has entered into a Distribution Agreement under which
Goldman Sachs, as agent, sells shares of each Portfolio on a continuous basis.
Goldman Sachs pays the cost of printing and distributing prospectuses to persons
who are not shareholders of the Trust (excluding preparation and typesetting
expenses) and of certain other distribution efforts. No compensation is payable
by the Trust to Goldman Sachs for such distribution services.    
     
The Administration Agreement and the Distribution Agreement provide that Goldman
Sachs may render similar services to others so long as its services under such
Agreements are not impaired thereby. The Administration Agreement provides that
the Trust will indemnify Goldman Sachs against certain liabilities (including
liabilities under the Federal securities laws relating to untrue statements or
omissions of material fact and actions that are in accordance with the terms of
the Administration Agreement and Distribution Agreement) or, in lieu thereof,
contribute to resulting losses.    

Shareholder Servicing Plan
    
As stated in the Portfolios' Prospectus, Institutions may enter into Servicing
Agreements with the Trust under which they provide (or arrange to have provided)
support services to their Customers or other investors who beneficially own such
shares in consideration of the Portfolios' payment of not more than .10%, .15%
and .25% (on an annualized basis) of the average daily net asset value of the
Class B, C and D Shares, respectively, of the U.S. Government Securities, Short-
Intermediate Bond, U.S. Treasury Index, Bond, Intermediate Bond and
International Bond Portfolios beneficially owned by such Customers or investors.
     
For the fiscal periods ended November 30 as indicated, the aggregate amount of
the Shareholder Service Fee incurred by each class of each Portfolio then in
existence was as follows:

The Trust's agreements with Institutions are governed by a Plan (called the
"Shareholder Servicing Plan") which has been adopted by the Board of Trustees.
Pursuant to the Shareholder Servicing Plan, the Board of Trustees will review,
at least quarterly, a written report of the amounts expended under the Trust's
agreements with Institutions and the purposes for which the expenditures were
made.  In addition, the arrangements with Institutions must be approved annually
by a majority of the Board of Trustees, including a majority of the Trustees who
are not "interested persons" of the Trust, as defined in the 1940 Act, and have
no direct or indirect financial interest in such arrangements.

The Board of Trustees has approved the arrangements with Institutions based on
information provided by the Trust's service contractors that there is a
reasonable likelihood that the arrangements will benefit the Portfolios and
their shareholders by affording the Portfolios greater flexibility in connection
with the servicing of the accounts of the beneficial owners of their shares in
an efficient manner.

Counsel and Auditors

Drinker Biddle & Reath LLP, with offices at 1345 Chestnut Street, Suite 1100,
Philadelphia, Pennsylvania 19107, serve as counsel to the Trust.
         
Ernst & Young LLP, independent auditors,  233 S. Wacker Drive, Chicago, Illinois
60606-6301, have been selected as auditors of the Trust.  In addition to audit
services, Ernst & Young LLP reviews the Trust's Federal and state tax returns,
and provides consultation and assistance on accounting, internal control and
related matters.

In-Kind Purchases

Payment for shares of a Portfolio may, in the discretion of Northern, be made in
the form of securities that are permissible investments for the Portfolio as
described in the Prospectus.  For further information about this form of
payment, contact Northern.  In connection with an in-kind securities payment, a
Portfolio will require, among other things, that the securities be valued on the
day of purchase in accordance with the pricing methods used by the Portfolio and
that the Portfolio receive satisfactory assurances that it will have good and
marketable title to the securities received by it; that the securities be in
proper form for transfer to the Portfolio; and that adequate information be
provided concerning the basis and other tax matters relating to the securities.

                                 PERFORMANCE INFORMATION
Each Portfolio that advertises an "average annual total return" for a class of
shares computes such return by determining the average annual compounded rate of
return during specified periods that equates the initial amount invested to the
ending redeemable value of such investment according to the following formula:
    
                                  T=(ERV) 1/n -1
                                    -----
                                      P                         
     Where:   T =    average annual total return;

              ERV =  ending redeemable value at the end of the applicable period
                     (or fractional portion thereof) of a hypothetical $1,000
                     payment made at the beginning of the 1, 5 or 10 year (or
                     other) period;
              P =    hypothetical initial payment of $1,000; and

              n =    period covered by the computation, expressed in terms of
                     years.

Each Portfolio that advertises an "aggregate total return" for a class of shares
computes such return by determining the aggregate compounded rates of return
during specified periods that likewise equate the initial amount invested to the
ending redeemable value of such investment.  The formula for calculating
aggregate total return is as follows:

    
                                  T=[(ERV)] -1
                                    -----
                                      P                         

    
The calculations set forth below are made assuming that (1) all dividends and
capital gain distributions are reinvested on the reinvestment dates at the price
per share existing on the reinvestment date and (2) all recurring fees charged
to all shareholder accounts are included.  The ending redeemable value (variable
"ERV" in the formula) is determined by assuming complete redemption of the
hypothetical investment after deduction of all nonrecurring charges at the end
of the measuring period.     

The average annual total returns and aggregate total returns shown below for the
Short-Intermediate Bond, U.S. Treasury Index and Bond

                                      B-41
<PAGE>
 
Portfolios include, for periods prior to the commencement of the Portfolios'
operations, the performance of a predecessor collective fund adjusted to reflect
the higher estimated fees and expenses applicable to such Portfolios' Class A
Shares at the time of their inception. Although all such predecessor collective
funds were managed by Northern for the periods stated in a manner and pursuant
to investment objectives that were equivalent in all material respects to the
management and investment objectives of the corresponding Portfolios, such
predecessor collective funds were not registered under the 1940 Act and were not
subject to certain investment restrictions imposed by the 1940 Act. If they had
been registered under the 1940 Act, performance might have been adversely
affected. The average annual total returns and aggregate total returns shown for
the Portfolios for their Class C and/or Class D Shares also include, for the
periods prior to the inception of such classes, the performance of the
Portfolios' Class A Shares. Because the fees and expenses of Class C and Class D
Shares are, respectively, 0.24% and 0.39% higher than those of Class A Shares,
actual performance for periods prior to the inception of Class C and Class D
Shares would have been lower if such higher fees and expenses had been taken
into account.

Following commencement of operations of the Portfolios, Goldman Sachs reimbursed
expenses to the Portfolios and voluntarily agreed to reduce a portion of its
administration fee for each Portfolio pursuant to the undertaking described
above under "Additional Trust Information - Administrator and Distributor" and
"-Investment Advisers, Transfer Agent and Custodian," and Northern waived a
portion of its investment advisory fees with respect to the Portfolios. The
average annual total returns and aggregate total returns of each Portfolio with
respect to Class A, Class C and Class D Shares, as applicable, are shown below
with and without such fee waivers and expense reimbursements.

The Portfolios' 30-day (or one month) standard yield described in the Prospectus
is calculated for each class of the Portfolios in accordance with the method
prescribed by the SEC for mutual funds:
    
                             Yield = 2[(ab+1) 6/1]
                                        --

       Where:     a = dividends and interest earned by a Portfolio during the
                  period;
                  b = expenses accrued for the period (net of reimbursements);
                  c = average daily number of shares outstanding during the
                  period entitled to receive dividends; and
                  d = net asset value per share on the last day of the period.

The performance of any investment is generally a function of portfolio quality
and maturity, type of investment and operating expenses.
Because of the different Servicing Fees and transfer agency fees payable with
respect to Class A, B, C and D Shares in a Portfolio, performance quotations for
shares of Class B, C and D of the Portfolio will be lower than the quotations
for Class A Shares of the Portfolio, which will not bear any fees for
shareholder support services and will bear minimal transfer agency fees.     

                                     TAXES

The following summarizes certain additional tax considerations generally
affecting the Portfolios and their shareholders that are not described in the
Portfolios' Prospectus.  No attempt is made to present a detailed explanation of
the tax treatment of the Portfolios or their shareholders, and the discussion
here and in the applicable Prospectus is not intended as a substitute for
careful tax planning.  Potential investors should consult their tax advisers
with specific reference to their own tax situations.

                                    General

Each Portfolio will elect to be taxed separately as a regulated investment
company under Part I of Subchapter M of Subtitle A, Chapter 1 of the Internal
Revenue Code of 1986, as amended (the "Code").  As a regulated investment
company, each Portfolio generally is exempt from Federal income tax on its net
investment income and realized capital gains which it distributes to
shareholders, provided that it distributes an amount equal to at least 90% of
its investment company taxable income (net investment income and the excess of
net short-term capital gain over net long-term capital loss), if any, for the
year (the "Distribution Requirement") and satisfies certain other requirements
of the Code that are described below.
    
In addition to satisfying the Distribution Requirement, each Portfolio must
derive with respect to a taxable year at least 90% of its gross income from
dividends, interest, certain payments with       


                                      B-49
<PAGE>
     
respect to securities loans and gains from the sale or other disposition of
stock or securities or foreign currencies, or from other income derived with
respect to its business of investing in such stock, securities or currencies
(the "Income Requirement").

In addition to the foregoing requirements, at the close of each quarter of its
taxable year, at least 50% of the value of each Portfolio's assets must consist
of cash and cash items, U.S. Government securities, securities of other
regulated investment companies, and securities of other issuers (as to which the
Portfolio has not invested more than 5% of the value of its total assets in
securities of such issuer and as to which the Portfolio does not hold more than
10% of the outstanding voting securities of such issuer) and no more than 25% of
the value of each Portfolio's total assets may be invested in the securities of
any one issuer (other than U.S. Government securities and securities of other
regulated investment companies), or in two or more issuers which such Portfolio
controls and which are engaged in the same or similar trades or businesses.

Each Portfolio intends to distribute to shareholders any excess of net long-term
capital gain over net short-term capital loss ("net capital gain") for each
taxable year.  Such gain is distributed as a capital gain dividend and is
taxable to shareholders as long-term capital gain (20% or 28% rate gain, as
applicable), regardless of the length of time the shareholder has held the
shares, whether such gain was recognized by the Portfolio prior to the date on
which a shareholder acquired shares of the Portfolio and whether the
distribution was paid in cash or reinvested in shares.  In addition, investors
should be aware that any loss realized upon the sale, exchange or redemption of
shares held for six months or less will be treated as a long-term capital loss
to the extent of the capital gain dividends the shareholder has received with
respect to such shares.  It is not expected that any distributions will qualify
for the dividends received deduction for corporations.

Ordinary income of individuals is taxable at a nominal maximum marginal
rate of 39.6%, but  because of limitations on itemized deductions otherwise
allowable and the phase-out of personal exemptions, the maximum effective
marginal rate of tax for some taxpayers may be higher.  The maximum tax rate on
capital gains for individuals is 20% if the property was held more than 18
months; for property held for more than 12 months, but not longer than 18
months, the maximum tax rate on capital gains is 28%.  Capital gains and
ordinary income of corporate taxpayers are both taxed at a nominal maximum rate
of 35%.     

If for any taxable year any Portfolio does not qualify as a regulated investment
company, all of its taxable income will be subject to tax at regular corporate
rates without any deduction for distributions to shareholders.  In such event,
all distributions (whether or not derived from exempt-interest income) would be

                                      B-50
<PAGE>
 
taxable as ordinary income, to the extent of such Portfolio's current and
accumulated earnings and profits and would be eligible for the dividends
received deduction in the case of corporate shareholders.

Shareholders will be advised annually as to the Federal income tax consequences
of distributions made by the Portfolios each year.

The Code imposes a non-deductible 4% excise tax on regulated investment
companies that fail to currently distribute an amount equal to specified
percentages of their ordinary taxable income and capital gain net income (excess
of capital gains over capital losses). Each Portfolio intends to make sufficient
distributions or deemed distributions of its ordinary taxable income and capital
gain net income each calendar year to avoid liability for this excise tax.

The Trust will be required in certain cases to withhold and remit to the United
States Treasury 31% of taxable dividends or 31% of gross sale proceeds paid to
any shareholder (i) who has provided either an incorrect tax identification
number or no number at all, (ii) who is subject to backup withholding by the
Internal Revenue Service for failure to report the receipt of taxable interest
or dividend income properly, or (iii) who has failed to certify to the Trust to
do so, that he is not subject to backup withholding or that he is an "exempt
recipient."

Taxation of Certain Financial Instruments

Special rules govern the Federal income tax treatment of financial instruments
that may be held by the Portfolios.  These rules may have a particular impact on
the amount of income or gain that a Portfolio must distribute to its respective
shareholders to comply with the Distribution Requirement and on the income or
gain qualifying under the Income Requirement described above.
    
Generally, futures contracts, options on futures contracts and certain foreign
currency contracts held by a Portfolio (collectively, the "Instruments") at the
close of its taxable year are treated for Federal income tax purposes as sold
for their fair market value on the last business day of such year, a process
known as "mark-to-market." Forty percent of any gain or loss resulting from such
constructive sales will be treated as short-term capital gain or loss and 60% of
such gain or loss will be treated as long-term capital gain or loss without
regard to the period a Portfolio has held the Instruments ("the 40%-60% rule").
The amount of any capital gain or loss actually realized by a Portfolio in a
subsequent sale or other disposition of those Instruments is adjusted to reflect
any capital gain or loss taken into account by the Portfolio in a prior year as
a result of the constructive sale of the Instruments.  Losses with respect to
futures contracts to sell related options and certain foreign currency
contracts, which     

                                      B-51
<PAGE>
 
    
are regarded as parts of a "mixed straddle" because their values fluctuate
inversely to the values of specific securities held by the Portfolios, are
subject to certain loss deferral rules which limit the amount of loss currently
deductible on either part of the straddle to the amount thereof which exceeds
the unrecognized gain (if any) with respect to the other part of the straddle,
and to certain wash sales regulations.  With respect to certain Instruments,
deductions for interest and carrying charges may not be allowed.
Notwithstanding the rules described above, with respect to futures contracts
which are part of a "mixed straddle" to sell related options and certain foreign
currency contracts which are properly identified as such, a Portfolio may make
an election which will exempt (in whole or in part) those identified futures
contracts, options and foreign currency contracts from the rules of Section 1256
of the Code including "the 40%-60% rule" and the mark-to-market on gains and
losses being treated for Federal income tax purposes as sold on the last
business day of each Portfolio's taxable year, but gains and losses will be
subject to such wash sales and loss deferral rules and the requirement to
capitalize interest and carrying charges.  Under Temporary Regulations, each
Portfolio would be allowed (in lieu of the foregoing) to elect either (1) to
offset gains or losses from portions which are part of a mixed straddle by
separately identifying each mixed straddle to which such treatment applies, or
(2) to establish a mixed straddle account for which gains and losses would be
recognized and offset on a periodic basis during the taxable year.  Under either
election, "the 40%-60% rule" will apply to the net gain or loss attributable to
the Instruments, but in the case of a mixed straddle account election, not more
than 50% of any net gain may be treated as long-term and no more than 40% of any
net loss may be treated as short-term.

Certain foreign currency contracts entered into by a Portfolio may be subject to
the "mark-to-market" process, but gain or loss will be treated as 100% ordinary
income or loss.  A foreign currency contract must meet the following conditions
in order to be subject to the mark-to-market rules described above: (1) the
contract must require delivery of, or settlement by reference to the value of, a
foreign currency of a type in which regulated futures contracts are traded; (2)
the contract must be entered into at arm's length at a price determined by
reference to the price in the interbank market; and (3) the contract must be
traded in the interbank market.  The Treasury Department has broad authority to
issue regulations under the provisions respecting foreign currency contracts.
As of the date of this Additional Statement, the Treasury Department has not
issued any such regulations.  Other foreign currency contracts entered into by a
Portfolio may result in the creation of one or more straddles for Federal income
tax purposes, in which case certain loss deferral and wash sales rules and the
requirement to capitalize interest and carrying charges may apply.     

                                      B-52
<PAGE>
 
Some of the non-U.S. dollar denominated investments that the Portfolios may
make, such as foreign debt securities and foreign currency contracts, may be
subject to provisions of the Code which govern the Federal income tax treatment
of certain transactions denominated in terms of a currency other than the U.S.
dollar or determined by reference to the value of one or more currencies other
than the U.S. dollar. The types of transactions covered by these provisions
include the following: (1) the acquisition of, or becoming the obligor under, a
bond or other debt instrument (including, to the extent provided in Treasury
regulations, preferred stock); (2) the accruing of certain trade receivables and
payables; and (3) the entering into or acquisition of any forward contract,
futures contract, option and similar financial instrument. The disposition of a
currency other than the U.S. dollar by a U.S. taxpayer also is treated as a
transaction subject to the special currency rules. However, regulated futures
contracts and nonequity options are generally not subject to the special
currency rules if they are or would be treated as sold for their fair market
value at year-end under the mark-to-market rules, unless an election is made to
have such currency rules apply. With respect to transactions covered by the
special rules, foreign currency gain or loss is calculated separately from any
gain or loss on the underlying transaction and is normally taxable as ordinary
gain or loss. A taxpayer may elect to treat as capital gain or loss foreign
currency gain or loss arising from certain identified forward contracts, futures
contracts and options that are capital assets in the hands of the taxpayer and
which are not part of a straddle. In accordance with Treasury regulations,
certain transactions that are part of a "Section 988 hedging transaction" (as
defined in the Code and Treasury regulations) may be integrated and treated as a
single transaction or otherwise treated consistently for purposes of the Code.
"Section 988 hedging transactions" are not subject to the mark-to-market or loss
deferral rules under the Code. Gain or loss attributable to the foreign currency
component of transactions engaged in by the Portfolios which are not subject to
the special currency rules (such as foreign equity investments other than
certain preferred stocks) is treated as capital gain or loss and is not
segregated from the gain or loss on the underlying transaction.

Foreign Investors

Foreign shareholders generally will be subject to U.S. withholding tax at a rate
of 30% (or a lower treaty rate, if applicable) on distributions by a Portfolio
of net interest income, other ordinary income, and the excess, if any, of net
short-term capital gain over net long-term capital loss for the year.  For this
purpose, foreign shareholders include individuals other than U.S. citizens,
residents and certain nonresident aliens, and foreign corporations,
partnerships, trusts and estates.  A foreign shareholder generally will not be
subject to U.S. income or withholding tax in respect of proceeds from or gain on
the redemption of shares or in respect of

                                      B-53
<PAGE>
 
capital gain dividends, provided such shareholder submits a statement, signed
under penalties of perjury, attesting to such shareholder's exempt status.
Different tax consequences apply to a foreign shareholder engaged in a U.S.
trade or business.  Foreign shareholders should consult their tax advisers
regarding the U.S. and foreign tax consequences of investing in a Portfolio.

Conclusion

The foregoing discussion is based on Federal tax laws and regulations which are
in effect on the date of this Additional Statement.  Such laws and regulations
may be changed by legislative or administrative action.  No attempt is made to
present a detailed explanation of the tax treatment of the Portfolio or its
shareholders, and the discussion here and in the Prospectus is not intended as a
substitute for careful tax planning.  Shareholders are advised to consult their
tax advisers with specific reference to their own tax situation, including the
application of state and local taxes.

Although each Portfolio expects to qualify as a "regulated investment company"
and to be relieved of all or substantially all Federal income taxes, depending
upon the extent of its activities in states and localities in which its offices
are maintained, in which its agents or independent contractors are located or in
which it is otherwise deemed to be conducting business, each Portfolio may be
subject to the tax laws of such states or localities.
    
                             DESCRIPTION OF SHARES

The Trust Agreement permits the Trust's Board of Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of one or more
separate series representing interests in one or more investment portfolios.
The Trust may hereafter create series in addition to the Trust's eighteen
existing series, which represent interests in the Trust's eighteen respective
portfolios, six of which are described in this Additional Statement.  The Trust
Agreement further permits the Board of Trustees to classify or reclassify any
unissued shares into additional series or classes within a series.  Pursuant to
such authority, the Trustees have authorized the issuance of an unlimited number
of shares of beneficial interest in four separate classes of shares in each of
its non-money market portfolios: Class A, B, C and D Shares.  Under the terms of
the Trust Agreement, each share of each Portfolio is without par value,
represents an equal proportionate interest in the particular Portfolio with each
other share of its class in the same Portfolio and is entitled to such dividends
and distributions out of the income belonging to the Portfolio as are declared
by the Trustees.  Upon any liquidation of a Portfolio, shareholders of each
class of a Portfolio are entitled to share pro rata in the net assets belonging
to that class available for distribution.  Shares do not have any preemptive or
conversion rights.  The right of     

                                      B-54
<PAGE>
 
    
redemption is described under "Investing-Redemption of Shares" in the
Prospectus. In addition, pursuant to the terms of the 1940 Act, the right of a
shareholder to redeem shares and the date of payment by a Portfolio may be
suspended for more than seven days (a) for any period during which the New York
Stock Exchange is closed, other than the customary weekends or holidays, or
trading in the markets the Portfolio normally utilizes is closed or is
restricted as determined by the SEC, (b) during any emergency, as determined by
the SEC, as a result of which it is not reasonably practicable for the Portfolio
to dispose of instruments owned by it or fairly to determine the value of its
net assets, or (c) for such other period as the SEC may by order permit for the
protection of the shareholders of the Portfolio. The Trust may also suspend or
postpone the recordation of the transfer of its shares upon the occurrence of
any of the foregoing conditions. In addition, shares of each Portfolio are
redeemable at the unilateral option of the Trust if the Trustees determine in
their sole discretion that failure to so redeem may have material adverse
consequences to the shareholders of the Portfolio. Shares when issued as
described in the Prospectus are validly issued, fully paid and nonassessable,
except as stated below.    

The proceeds received by each Portfolio for each 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 and constitute the underlying assets of that Portfolio.  The underlying
assets of each Portfolio will be segregated on the books of account, and will be
charged with the liabilities in respect to that Portfolio and with a share of
the general liabilities of the Trust.  Expenses with respect to the Portfolios
are normally allocated in proportion to the net asset value of the respective
Portfolios except where allocations of direct expenses can otherwise be fairly
made.
    
Rule 18f-2 under the 1940 Act provides that any matter required by the
provisions of the 1940 Act or applicable state law, or otherwise, to be
submitted 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 investment portfolio affected by such matter.  Rule 18f-2 further provides
that an investment portfolio shall be deemed to be affected by a matter unless
the interests of each investment portfolio in the matter are substantially
identical or the matter does not affect any interest of the investment
portfolio.  Under the Rule, the approval of an investment advisory agreement or
any change in a fundamental investment policy would be effectively acted upon
with respect to an investment portfolio only if approved by a majority of the
outstanding shares of such investment portfolio.  However, the Rule also
provides that the ratification of the appointment of independent accountants,
the approval of principal underwriting contracts and the election of Trustees
are exempt from the separate     

                                      B-55
<PAGE>
 
    
voting requirements stated above.  In addition, shareholders of each of the
classes in a particular investment portfolio have equal voting rights except
that only shares of a particular class of an investment portfolio will be
entitled to vote on matters submitted to a vote of shareholders (if any)
relating to shareholder servicing expenses and transfer agency fees that are
payable by that class.

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 Shareholders, including the election of Trustees (this
method of voting being referred to as "dollar-based voting").  However, to the
extent required by the 1940 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 meeting.  The Shareholders
of the Trust will have voting rights only with respect to the limited number of
matters specified in the Trust Agreement and such other matters as the Trustees
may determine or may be required by law.

The Trust Agreement authorizes the Trustees, without Shareholder approval
(except as stated in the next paragraph), 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
substantially all of the assets of a series of the Trust in the securities of
another open-end investment company or pooled portfolio.

The Trust Agreement also authorizes the Trustees, in connection with the merger,
consolidation, termination or other reorganization of the Trust or any series or
class, to classify the Shareholders of any class into one or more separate
groups and to provide for the different treatment of Shares held by the
different groups, provided that such merger, consolidation, termination or other
reorganization is approved by a majority of the outstanding voting securities
(as defined in the 1940 Act) of each group of Shareholders that are so
classified.

The Trust Agreement permits the Trustees to amend the Trust Agreement without a
Shareholder vote.  However, Shareholders of the Trust have the right to vote on
any amendment (i) that would        

                                      B-56
<PAGE>
     
adversely 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 Trust Agreement; or (iv) that the Trustees determine to submit to
Shareholders.

The Trust Agreement 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 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.

Under the Delaware Business Trust Act (the "Delaware Act"), shareholders are not
personally liable for obligations of the Trust.  The Delaware Act entitles the
Trust to the same limitation of liability as is available to shareholders of
private for-profit corporations.  However, no similar statutory or other
authority limiting business trust shareholder liability exists in many other
states.  As a result, to the extent that the Trust or a shareholder is subject
to the jurisdiction of courts in such other states, those courts may not apply
Delaware law and may subject the shareholders to liability.  To offset this
risk, the Trust Agreement (i) contains an express disclaimer of shareholder
liability for acts or obligations of the Trust and requires that notice of such
disclaimer be given in each agreement, obligation and instrument entered into or
executed by the Trust or its Trustees and (ii) provides for indemnification out
of the property of the applicable series of the Trust of any shareholder held
personally liable for the obligations of the Trust 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.  Thus, the risk of a shareholder incurring financial
loss beyond his or her investment because of shareholder liability is limited to
circumstances in which all of the following factors are present: (1) a court
refuses to apply Delaware law; (2) the liability arises under tort law or, if
not, no contractual limitation of liability is in effect; and (3) the applicable
series of the is unable to meet its obligations.

The Trust Agreement provides that the Trustees will not be liable to any person
other than the Trust or a shareholder and that a Trustee will not be liable for
any act as a Trustee.  However, nothing in the Trust Agreement protects a
Trustee against any liability to which he or she would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence or reckless     

                                      B-57
<PAGE>
 
    
disregard of the duties involved in the conduct of his or her office. The Trust
Agreement provides for indemnification of Trustees, officers and agents of the
Trust unless the recipient is 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.

The Trust Agreement provides that each shareholder, by virtue of becoming such,
will be held to have expressly assented and agreed to the terms of the Trust
Agreement and to have become a party thereto.

In addition to the requirements of Delaware law, the Trust Agreement provides
that a Shareholder of the Trust may bring a derivative action on behalf of the
Trust 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 Trust, or 10% of the outstanding Shares 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 Shareholder request and to investigate the basis
of such claim. The Trust Agreement also provides that no person, other than the
Trustees, who is not a Shareholder of a particular series or class shall be
entitled to bring any derivative action, suit or other proceeding on behalf of
or with respect to such series or class. 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 Shareholders 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 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 Trust Agreement with
respect to such 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.

As of March 11, 1998, substantially all of the Portfolios' outstanding shares
were held of record by Northern for the benefit of its customers and the
customers of its affiliates and correspondent banks that have invested in the
Portfolios. As of the same date, the Trust's Trustees and officers owned
beneficially less than 1% of the outstanding shares of each Portfolio. Northern
has advised the Trust that the following persons (whose mailing address is: c/o

The Prospectus and this Additional Statement do not contain all the information
included in the Registration Statement filed with the SEC under the Securities
Act of 1933 with respect to the securities offered by the Trust's 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.

Each Portfolio is responsible for the payment of its expenses. Such expenses
include, without limitation, the fees and expenses payable to Northern, NTQA and
Goldman Sachs, brokerage fees and commissions, fees for the registration or
qualification of Portfolio shares under Federal or state securities laws,
expenses of the organization of the Portfolio, taxes, 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 Trust for violation of any law, legal, tax
and auditing fees and expenses, Servicing Fees, expenses of preparing and
printing prospectuses, statements of additional information, proxy materials,
reports and notices and the printing and distributing of the same to the Trust's
shareholders and regulatory authorities, compensation and expenses of its
Trustees, expenses of industry organizations such as the Investment Company
Institute, miscellaneous expenses and extraordinary expenses incurred by the
Trust.

The term "majority of the outstanding shares" of either the Trust or a
particular Portfolio means, with respect to the approval of an investment
advisory agreement or a change in a fundamental investment policy, the vote of
the lesser of (i) 67% or more of the shares of the Trust or such Portfolio

Description of Bond Ratings

The following summarizes the highest six ratings used by Standard & Poor's
Ratings Group, Inc., a division of McGraw Hill ("S&P") for corporate and
municipal debt:

     AAA: Debt rated AAA has the highest rating assigned by S&P. The obligor's
     capacity to meet its financial commitment on the obligation is extremely
     strong.     

     AA: Debt rated AA differs from AAA issues only in a small degree. The
     obligor's capacity to meet its financial commitment on the obligation is
     very strong.     

     A: Debt rated A is somewhat more susceptible to the adverse effects of
     changes in circumstances and economic conditions than debt in higher rated
     categories. However, the obligor's capacity to meet its financial
     commitment on the obligation is still strong.     

     BBB: Debt 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 it's financial
     commitment on the obligation.     

     BB and B: Debt rated BB and B is regarded, on balance, as predominantly
     speculative with respect to capacity to pay interest and repay principal in
     accordance with the terms of the obligation. Debt rated BB is less
     vulnerable to non-payment 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. Debt rated B is more
     vulnerable to non-payment but the obligor currently has the capacity to
     meet its financial commitment on the obligation. Adverse business,
     financial, or economic conditions will likely impair the obligor's capacity
     or willingness to meet its financial commitment on the obligation. The B
     rating category is also used for debt subordinated to senior debt that is
     assigned an actual or implied BB or BB- rating.     

To provide more detailed indications of credit quality, the ratings AA and lower
may be modified by the addition of a plus or minus sign to show relative
standing within these major rating categories.

S&P may attach the rating "r" to highlight derivative, hybrid and certain other
obligations that S&P believes may experience high

                                      1-A
<PAGE>
volatility or high variability in expected returns due to non-credit risks.

The following summarizes the highest six ratings used by Moody's Investors
Service, Inc.  ("Moody's") for corporate and municipal long-term debt:

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

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

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

     Baa: Bonds that are rated Baa are considered 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 and B: Bonds that possess one of these ratings provide questionable
     protection of interest and principal. Ba indicates some speculative
     elements. B indicates a general lack of characteristics of desirable
     investment.

    
The foregoing ratings for corporate and municipal long-term debt are sometimes
presented in parenthesis preceded with a "con", indicating the bonds are rated
conditionally. Such parenthetical rating denotes the probable credit stature
upon completion of some act or the fulfillment of some condition. The notation
(P) when applied to forward delivery bonds indicates that the rating is        


                                      2-A
<PAGE>
   
provisional pending delivery of the bonds. The rating may be revised prior to
delivery if changes occur in the legal documents or the underlying credit
quality of the bonds.     

The following summarizes the highest six ratings used by Duff & Phelps Credit
Rating Co. ("D&P") for corporate and municipal long-term debt:

     AAA: Debt rated AAA is of the highest credit quality. The risk factors are
     considered to be negligible, being only slightly more than for risk-free
     U.S. Treasury debt.     

     AA: Debt rated AA is of high credit quality. Protection factors are strong.
     Risk is modest but may vary slightly from time to time because of economic
     conditions.     

     A: Bonds that are rated A have protection factors which are average but
     adequate. However risk factors are more variable and greater in periods of
     economic stress.     

     BBB: Bonds that are rated BBB have below average protection factors but
     such protection factors are still considered sufficient for prudent
     investment. Considerable variability in risk during economic cycles.

     BB and B: Bonds that are rated BB or B are below investment grade. Bonds
     rated BB are deemed likely to meet obligations when due. Bonds rated B
     possess the risk that the obligations will not be met when due.

To provide more detailed indications of credit quality, the ratings AA and lower
may be modified by the addition of a plus or minus sign to show relative
standing within these major categories.

The following summarizes the highest six ratings used by Fitch IBCA, Inc.
("Fitch") 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 investment risk and
     are assigned only in case of exceptionally strong capacity for timely
     payment of financial commitments. This capacity is unlikely to be affected
     by reasonably foreseeable events.     

     AA: Bonds considered to be investment grade and of very high credit
     quality. These ratings denote a very low expectation of investment risk and
     indicate very strong capacity for timely payment of financial commitments.
     Because bonds related in the "AAA" and "AA" categories are not
     significantly vulnerable to foreseeable future developments, short-term
     debt of these issuers is generally rated "F1+."     


                                      3-A
<PAGE>
 
     A: Bonds considered to be investment grade and of high credit quality. The
     obligor's ability to pay interest and repay principal is considered to be
     strong, but may be more vulnerable to adverse changes in economic
     conditions and circumstances than bonds with 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
     investment risk. The capacity for timely payment of financial commitments
     is adequate, but adverse changes in economic conditions and circumstances,
     however, are more likely to impair this category.    

     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.     

To provide more detailed indications of credit quality, the Fitch ratings "AA"
and lower may be modified by the addition of a plus (+) or minus (-) sign to
show relative standing within these major rating categories.

Description of Municipal Note Ratings

The following summarizes the two highest ratings by S&P for short-term municipal
notes:

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

     SP-2:  Satisfactory capacity to pay principal and interest.

The following summarizes the two highest ratings used by Moody's for short-term
municipal notes and variable rate demand obligations:

     MIG-1/VMIG-1:  Obligations bearing these designations are of the best
     quality, enjoying strong protection by established

                                      4-A
<PAGE>
     cash flows, superior liquidity support or demonstrated broad-based access
     to the market for refinancing.

     MIG-2/VMIG-2: Obligations bearing these designations are of high quality
     with margins of protection ample although not as large as in the preceding
     group.
    
The two highest rating categories of D&P for short-term debt are D-1 and D-2.
D&P employs three designations, D-1+, D-1 and D-1-, within the highest rating
category.  D-1+ indicates 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 indicates very high certainty of timely
payment.  Liquidity factors are excellent and supported by good fundamental
protection factors.  Risk factors are minor.  D-1- indicates high certainty of
timely payment.  Liquidity factors are strong and supported by good fundamental
protection factors.  Risk factors are very small.  D-2 indicates 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&P uses the fixed-income ratings described above under "Description of Bond
Ratings" for tax-exempt notes and other short-term obligations.  Fitch uses the
short-term ratings described below under "Description of Commercial Paper
Ratings" for municipal notes.

Description of Commercial Paper Ratings
    
Commercial paper rated A-1 by S&P indicates that the obligor's capacity to meet
its financial commitment is strong.  Those issues for which the obligor's
capacity to meet its financial commitment on the obligation is extremely strong
are denoted in A-1+.  Capacity for timely payment on commercial paper rated A-2
is satisfactory but the obligor's capacity to meet its financial commitment on
the obligation is not as high as for issues designated A-1.     
    
The rating Prime-1 is the highest commercial paper rating assigned by Moody's.
Issuers or related supporting institutions rated Prime-1 are considered to have
a superior capacity for repayment of short-term promissory obligations.  Prime-1
repayment capacity will often be evidenced by the following characteristics:
leading market positions in well-established industries; high rates of return on
funds employed; conservative capitalization structures with moderate reliance on
debt and ample asset protection; broad margins in earning 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.     

                                      5-A
<PAGE>

    
Issuers or related supporting institutions rated Prime-2 are considered to have
strong capacity for repayment of short-term promissory 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, will be more subject
to variation. Capitalization characteristics, while still appropriate, may be
more affected by external conditions. Ample alternate liquidity is
maintained.    

     The following summarizes the highest ratings used by Fitch for short-term
obligations:    

     F1+ securities possess exceptionally strong credit quality. Issues assigned
     this rating are regarded as having the strongest degree of assurance for
     timely payment.

     F1 securities possess very strong credit quality. Issues assigned this
     rating reflect an assurance of timely payment only slightly less in degree
     than issues rated F1+.

     F2 securities possess good credit quality. Issues assigned this rating have
     a satisfactory degree of assurance for timely payment, but the margin of
     safety is not as great as the F1+ and F1 categories.    
     
     D&P uses the short-term ratings described above under "Description of Note
Ratings" for commercial paper.

                                   APPENDIX B

As stated in their Prospectus, the Portfolios may enter into futures
transactions and options thereon. Such transactions are described more fully in
this Appendix.

I.  Interest Rate Futures Contracts

     Use of Interest Rate Futures Contracts.  Bond prices are established in
both the cash market and the futures market.  In the cash market, bonds are
purchased and sold with payment for the full purchase price of the bond being
made in cash, generally within three business days after the trade.  In the
futures market, only a contract is made to purchase or sell a bond in the future
for a set price on a certain date.  Historically, the prices for bonds
established in the futures markets have tended to move generally in the
aggregate in concert with the cash market prices and have maintained fairly
predictable relationships.  Accordingly, a Portfolio could use interest rate
futures contracts as a defense, or hedge, against anticipated interest rate
changes.  As described below, this could include the use of futures contract
sales to protect against expected increases in interest rates and the use of
futures contract purchases to offset the impact of interest rate declines.

     A Portfolio presently could accomplish a similar result to that which it
hopes to achieve through the use of futures contracts by selling bonds with long
maturities and investing in bonds with short maturities when interest rates are
expected to increase, or conversely, selling short-term bonds and investing in
long-term bonds when interest rates are expected to decline.  However, because
of the liquidity that is often available in the futures market, the protection
is more likely to be achieved, perhaps at a lower cost and without changing the
rate of interest being earned by a Portfolio, through using futures contracts.

     Interest rate futures contracts can also be used by a Portfolio for
nonhedging (speculative) purposes to increase total return.

     Description of Interest Rate Futures Contracts.  An interest rate futures
contract sale would create an obligation by a Portfolio, as seller, to deliver
the specific type of financial instrument called for in the contract at a
specific future time for a specified price.  A futures contract purchase would
create an obligation by a Portfolio, as purchaser, to take delivery of the
specific type of financial instrument at a specific future time at a specific
price.  The specific securities delivered or taken, respectively, at settlement
date, would not be determined until at or near that date.  The determination
would be in accordance with the rules of the exchange on which the futures
contract sale or purchase was made.

                                      1-B
<PAGE>
 
     Although interest rate futures contracts by their terms call for actual
delivery or acceptance of securities, in most cases the contracts are closed out
before a settlement date without the making or taking of delivery of securities.
Closing out a futures contract sale is effected by a Portfolio's entering into a
futures contract purchase for the same aggregate amount of the specific type of
financial instrument and the same delivery date. If the price of a sale exceeds
the price of the offsetting purchase, a Portfolio is immediately paid the
difference and thus realizes a gain.  If the offsetting purchase price exceeds
the sale price, a Portfolio pays the difference and realizes a loss. Similarly,
the closing out of a futures contract purchase is effected by a Portfolio
entering into a futures contract sale.  If the offsetting sale price exceeds the
purchase price, a Portfolio realizes a gain, and if the purchase price exceeds
the offsetting sale price, a Portfolio realizes a loss.

     Interest rate futures contracts are traded in an auction environment on the
floors of several exchanges--principally, the Chicago Board of Trade, the
Chicago Mercantile Exchange and the -New York Futures Exchange.  A Portfolio
would deal only in standardized contracts on recognized exchanges.  Each
exchange guarantees performance under contract provisions through a clearing
corporation, a nonprofit organization managed by the exchange membership.

     A public market now exists in futures contracts covering various financial
instruments including long-term United States Treasury Bonds and Notes;
Government National Mortgage Association (GNMA) modified pass-through mortgage
backed securities; three-month United States Treasury Bills; and ninety-day
commercial paper.  A Portfolio may trade in any interest rate futures contracts
for which there exists a public market, including, without limitation, the
foregoing instruments.

II.  Index Futures Contracts
    
III. General.  A bond index assigns relative values to the bonds included in the
index which fluctuates with changes in the market values of the bonds included.
                                                                                
     A Portfolio may sell index futures contracts in order to offset a decrease
in market value of its portfolio securities that might otherwise result from a
market decline.  A Portfolio may do so either to hedge the value of its
portfolio as a whole, or to protect against declines, occurring prior to sales
of securities, in the value of the securities to be sold.  Conversely, a
Portfolio may purchase index futures contracts in anticipation of purchases of
securities.  A long futures position may be terminated without a corresponding
purchase of securities.

                                      2-B
<PAGE>
 
     In addition, a Portfolio may utilize index futures contracts in
anticipation of changes in the composition of its portfolio holdings.  For
example, in the event that a Portfolio expects to narrow the range of industry
groups represented in its holdings it may, prior to making purchases of the
actual securities, establish a long futures position based on a more restricted
index, such as an index comprised of securities of a particular industry group.
A Portfolio may also sell futures contracts in connection with this strategy, in
order to protect against the possibility that the value of the securities to be
sold as part of the restructuring of the portfolio will decline prior to the
time of sale.

     Index futures contracts may also be used by a Portfolio for non-hedging
(speculative) purposes, to increase total return.

III. Futures Contracts on Foreign Currencies (International Bond Portfolio)

     A futures contract on foreign currency creates a binding obligation on one
party to deliver, and a corresponding obligation on another party to accept
delivery of, a stated quantity of foreign currency, for an amount fixed in U.S.
dollars.  Foreign currency futures may be used by a Portfolio for hedging
purposes in anticipation of fluctuations in exchange rates between the U.S.
dollars and other currencies arising from multinational transactions.

     The International Bond Portfolio may also use futures contracts on foreign
currencies for non-hedging (speculative) purposes to increase total return.

IV.  Margin Payments

     Unlike purchases, or sales of portfolio securities, no price is paid or
received by a Portfolio upon the purchase or sale of a futures contract.
Initially, the Portfolio will be required to deposit with the broker or in a
segregated account with the Custodian or a sub-custodian an amount of liquid
assets, known as initial margin, based on the value of the contract.  The nature
of initial margin in futures transactions is different from that of margin in
security transactions in that futures contract margin does not involve the
borrowing of funds by the customer to finance the transactions.  Rather, the
initial margin is in the nature of a performance bond or good faith deposit on
the contract which is returned to the Portfolio upon termination of the futures
contract assuming all contractual obligations have been satisfied.  Subsequent
payments, called variation margin, to and from the broker, will be made on a
daily basis as the price of the underlying instruments fluctuates making the
long and short positions in the futures contract more or less valuable, a
process known as marking-to-the-market.  For example, when a particular

                                      3-B
<PAGE>
 
Portfolio has purchased a futures contract and the price of the contract has
risen in response to a rise in the underlying instruments, that position will
have increased in value and the Portfolio will be entitled to receive from the
broker a variation margin payment equal to that increase in value.  Conversely,
where the Portfolio has purchased a futures contract and the price of the future
contract has declined in response to a decrease in the underlying instruments,
the position would be less valuable and the Portfolio would be required to make
a variation margin payment to the broker.  At any time prior to expiration of
the futures contract, the Portfolio's adviser may elect to close the position by
taking an opposite position, subject to the availability of a secondary market,
which will operate to terminate the Portfolio's position in the futures
contract.  A final determination of variation margin is then made, additional
cash is required to be paid by or released to the Portfolio, and the Portfolio
realizes a loss or gain.

V.  Risks of Transactions in Futures Contracts

     There are several risks in connection with the use of futures by the
Portfolios.  In connection with the use of futures for hedging purposes, one
risk arises because of the imperfect correlation between movements in the price
of the futures and movements in the price of the instruments which are the
subject of the hedge.  The price of the future may move more than or less than
the price of the instruments being hedged.  If the price of the futures moves
less than the price of the instruments which are the subject of the hedge, the
hedge will not be fully effective but, if the price of the instruments being
hedged has moved in an unfavorable direction, the Portfolio would be in a better
position than if it had not hedged at all.  If the price of the instruments
being hedged has moved in a favorable direction, this advantage will be
partially offset by the loss on the futures.  If the price of the futures moves
more than the price of the hedged instruments, the Portfolio involved will
experience either a loss or gain on the futures which will not be completely
offset by movements in the price of the instruments which are the subject of the
hedge.  To compensate for the imperfect correlation of movements in the price of
instruments being hedged and movements in the price of futures contracts, the
Portfolio may buy or sell futures contracts in a greater dollar amount than the
dollar amount of instruments being hedged if the volatility over a particular
time period of the prices of such instruments has been greater than the
volatility over such time period of the futures, or if otherwise deemed to be
appropriate by the Investment Advisers.  Conversely, the Portfolios may buy or
sell fewer futures contracts if the volatility over a particular time period of
the prices of the instruments being hedged is less than the volatility over such
time period of the futures contract being used, or if otherwise deemed to be
appropriate by the Investment Advisers.  It is also possible that, where a
Portfolio had sold futures to hedge its portfolio against

                                      4-B
<PAGE>
 
a decline in the market, the market may advance and the value of instruments
held in the Portfolio may decline.  If this occurred, the Portfolio would lose
money on the futures and also experience a decline in value in its portfolio
securities.

     Where futures are purchased to hedge against a possible increase in the
price of securities before a Portfolio is able to invest its cash (or cash
equivalents) in an orderly fashion, it is possible that the market may decline
instead; if the Portfolio then concludes not to invest its cash at that time
because of concern as to possible further market decline or for other reasons,
the Portfolio will realize a loss on the futures contract that is not offset by
a reduction in the price of the instruments that were to be purchased.

     In addition to the possibility that there may be an imperfect correlation,
or no correlation at all, between movements in the futures and the instruments
being hedged, the price of futures may not correlate perfectly with movement in
the cash market due to certain market distortions.  Rather than meeting
additional margin deposit requirements, investors may close futures contracts
through off-setting transactions which could distort the normal relationship
between the cash and futures markets.  Second, with respect to financial futures
contracts, the liquidity of the futures market depends on participants entering
into off-setting transactions rather than making or taking delivery.  To the
extent participants decide to make or take delivery, liquidity in the futures
market could be reduced thus producing distortions.  Third, from the point of
view of speculators, the deposit requirements in the futures market are less
onerous than margin requirements in the securities market.  Therefore, increased
participation by speculators in the futures market may also cause temporary
price distortions.  Due to the possibility of price distortion in the futures
market, and because of the imperfect correlation between the movements in the
cash market and movements in the price of futures, a correct forecast of general
market trends or interest rate movements by the Investment Advisers may still
not result in a successful hedging transaction over a short time frame.

     Positions in futures may be closed out only on an exchange or board of
trade which provides a secondary market for such futures.  Although the
Portfolios intend to purchase or sell futures only on exchanges or boards of
trade where there appear to be active secondary markets, there is no assurance
that a liquid secondary market on any exchange or board of trade will exist for
any particular contract or at any particular time.  In such event, it may not be
possible to close a futures investment position, and in the event of adverse
price movements, the Portfolios would continue to be required to make daily cash
payments of variation margin.  However, in the event futures contracts have been
used to hedge portfolio securities, such securities will generally not be sold
until the futures contract can be terminated.  In such

                                      5-B
 
<PAGE>
 
circumstances, an increase in the price of the securities, if any, may partially
or completely offset losses on the futures contract.  However, as described
above, there is no guarantee that the price of the securities will in fact
correlate with the price movements in the futures contract and thus provide an
offset on a futures contract.

     Further, it should be noted that the liquidity of a secondary market in a
futures contract may be adversely affected by "daily price fluctuation limits"
established by commodity exchanges which limit the amount of fluctuation in a
futures contract price during a single trading day.  Once the daily limit has
been reached in the contract, no trades may be entered into at a price beyond
the limit, thus preventing the liquidation of open futures positions.  The
trading of futures contracts is also subject to the risk of trading halts,
suspensions, exchange or clearing house equipment failures, government
intervention, insolvency of a brokerage firm or clearing house or other
disruptions of normal activity, which could at times make it difficult or
impossible to liquidate existing positions or to recover excess variation margin
payments.
    
     Successful use of futures by the Portfolios is also subject to the
Investment Advisers' ability to predict correctly movements in the direction of
the market.  For example, if a particular Portfolio has hedged against the
possibility of a decline in the market adversely affecting securities held by it
and securities prices increase instead, the Portfolio will lose part or all of
the benefit to the increased value of its securities which it has hedged because
it will have offsetting losses in its futures positions.  In addition, in such
situations, if the Portfolio has insufficient cash, it may have to sell
securities to meet daily variation margin requirements.  Such sales of
securities may be, but will not necessarily be, at increased prices which
reflect the rising market.  The Portfolios may have to sell securities at a time
when they may be disadvantageous to do so.     

     Futures purchased or sold by the International Bond Portfolio (and related
options) may be traded in foreign instruments.  Participation in foreign futures
and foreign options transactions involves the execution and clearing of trades
on or subject to the rules of a foreign board of trade.  Neither the National
Futures Association nor any domestic exchange regulates activities of any
foreign boards of trade, including the execution, delivery and clearing of
transactions, or has the power to compel enforcement of the rules of a foreign
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, customers who
trade foreign futures of foreign options contracts may not be afforded certain
of the protective

                                      6-B
<PAGE>
 
measures provided by the Commodity Exchange Act, the Commodity Futures Trading
Commission's ("CFTC") 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, the
investments of the International Bond Portfolio's in foreign futures or foreign
options transactions may not be provided the same protections in respect of
transactions on United States futures exchanges.  In addition, the price of any
foreign futures or foreign options contract and, therefore the potential profit
and loss thereon may be affected by any variance in the foreign exchange rate
between the time an order is placed and the time it is liquidated, offset or
exercised.

VI.  Options on Futures Contracts

     The Portfolios may purchase and write options on the futures contracts
described above.  A futures option gives the holder, in return for the premium
paid, the right to buy (call) from or sell (put) to the writer of the option a
futures contract at a specified price at any time during the period of the
option.  Upon exercise, the writer of the option is obligated to pay the
difference between the cash value of the futures contract and the exercise
price.  Like the buyer or seller of a futures contract, the holder, or writer,
of an option has the right to terminate its position prior to the scheduled
expiration of the option by selling, or purchasing an option of the same series,
at which time the person entering into the closing transaction will realize a
gain or loss.  A Portfolio will be required to deposit initial margin and
variation margin with respect to put and call options on futures contracts
written by it pursuant to brokers' requirements similar to those described
above.  Net option premiums received will be included as initial margin
deposits.

     Investments in futures options involve some of the same considerations that
are involved in connection with investments in futures contracts (for example,
the existence of a liquid secondary market).  See "Risks of Transactions in
Futures Contracts" above.  In addition, the purchase or sale of an option also
entails the risk that changes in the value of the underlying futures contract
will not correspond to changes in the value of the option purchased.  Depending
on the pricing of the option compared to either the futures contract upon which
it is based, or upon the price of any underlying instruments, an option may or
may not be less risky than ownership of the futures contract or such
instruments.  In general, the market prices of options can be expected to be
more volatile than the market prices on the underlying futures contract.
Compared to the purchase or sale of futures contracts, however, the purchase of
call or put options on futures contracts may, unlike futures contracts where the
risk of loss is potentially unlimited, frequently involve less potential

                                      7-B
<PAGE>
 
risk to the Portfolio because the maximum amount at risk is the premium paid for
the options (plus transaction costs).  The writing of an option on a futures
contract involves risks similar to those risks relating to the sale of futures
contracts.

VII.  Other Matters

     Accounting for futures contracts will be in accordance with generally
accepted accounting principles.

MANAGEMENT'S DISCUSSION OF PORTFOLIO PERFORMANCE
BENCHMARK BOND PORTFOLIO
 
  Overall, interest rates changed only marginally during the fiscal year, even
though the first half of the year witnessed a meaningful rise in rates, and the
second half saw an equally meaningful decline. Similarly, non-Treasury spreads
generally tightened early in the year while reversing course later. Both
patterns--but the interest rate move in particular--reflected the conflicting
signals given by cyclical versus secular economic forces. An economy growing
faster than what many consider trend growth, and the inflation and Federal
Reserve tightening fears it engendered, captured investors' attention early and
resulted in increasing rates. Positive secular developments and the resulting
declines in actual measured inflation and the fiscal deficit, among other
positive trends, eventually eased cyclical fears and pushed rates down. The
turmoil in Southeast Asia late in the period added to the positive backdrop. In
reality, this disturbance can be viewed as an effect of the secular
developments as opposed to a cause of the market rally.
  For the year, the flattening of the yield curve, the outperformance of the
mortgage sector and disparate sector performance in a generally flat corporate
sector drove the fixed-income market's relative performance. The Portfolio
posted solid relative returns primarily on good securities and sector selection
decisions.
  As we begin the new fiscal year, the Portfolio is positioned with moderately
greater interest rate sensitivity than its benchmark, and it is overweighted in
non-Treasury sectors. A calendar-year-end widening in asset-backed security
spreads has led to increased exposure in that sector. The Portfolio continues
to maintain a high quality profile.

MANAGEMENT'S DISCUSSION OF PORTFOLIO PERFORMANCE

BENCHMARK INTERMEDIATE BOND PORTFOLIO
 
Despite the continuing crisis in Southeast Asia, U.S. stock prices firmed
during November 1997 as foreign countries' restructuring plans and
International Monetary Fund aid came into focus. While this support did not
flow as strongly into the corporate and mortgage bond market, it at least
halted the underperformance that these sectors experienced in October 1997.
This movement caused U.S. corporate bonds to end the year virtually unchanged
relative to Treasury bonds. On the other hand, mortgage-backed securities
performed strongly based on a year-long decline in volatility.
  The Intermediate Bond Portfolio commenced operations on August 1, 1997, with
initial investments in Treasury securities and some select positions in
corporate, mortgage and asset-backed securities. Given the recent lag in spread
sector prices, the Portfolio did experience some modest underperformance due to
its overweighting in corporate and mortgage bonds. Based on current interest
rate and spread levels, these markets look more attractive, and we expect to
hold these positions going forward.

Benchmark International Bond Portfolio
 
The fiscal year's global financial environment was marked by certain events
that had negative implications for the Portfolio's performance. First, there
was a material increase in the price of longer-dated, high-quality bonds,
primarily due to improved inflation and weaker-than-expected global growth. The
Asian financial crisis further benefited bonds, as next year's growth and
inflation expectations were revised lower. Second, the dollar appreciated
sharply against major currencies due to strong domestic fundamentals and the
global flight to quality/liquidity. The greenback gained more than 10% versus
both the yen and the Deutschemark. The notable exception to the trend was the
British pound, which was virtually unchanged versus the dollar.
  Given the Portfolio's international status, the majority of its market
exposure was to both foreign bonds and currencies. As such, the past year's
environment was by no means ideal. Although participants benefited from a rise
in bond prices, the dollar's sharp appreciation more than offset these gains
for U.S.-based investors. Of some consolation was the Portfolio's
outperformance versus its benchmark, which was largely due to an underweighted
position in Japan and an overweighted position in the United Kingdom.
  As the new fiscal year begins, we retain the Portfolio's interest rate
posture, given our constructive outlook for global inflation and generally
attractive real yields. We also maintain a strong bias toward very high-quality
issuers. Because the Portfolio is invested in non-U.S. bonds and currencies,
returns continue to be strongly influenced by the direction of the dollar.

Management's Discussion of Portfolio Performance

Benchmark Short-Intermediate Bond Portfolio
 
Overall, interest rates changed only marginally during the fiscal year, even
though the first half of the year witnessed a meaningful rise in rates, and the
second half saw an equally meaningful decline. Similarly, non-Treasury spreads
generally tightened early in the year while reversing course later. Both
patterns--but the interest rate move in particular--reflected the conflicting
signals given by cyclical versus secular economic forces. An economy growing
faster than what many consider trend growth, and the inflation and Federal
Reserve tightening fears it engendered, captured investors' attention early and
resulted in increasing rates. Positive secular developments and the resulting
declines in actual measured inflation and the fiscal deficit, among other
positive trends, eventually eased cyclical fears and pushed rates down. The
turmoil in Southeast Asia late in the period added to the positive backdrop. In
reality, this disturbance can be viewed as an effect of the secular
developments as opposed to a cause of the market rally.
  For the year, the flattening of the yield curve, the outperformance of the
mortgage sector and disparate sector performance in a generally flat corporate
sector drove the fixed-income market's relative performance. The Portfolio
outperformed its benchmark before fees, though it slightly trailed on an after-
fee basis. With little net change in interest rates or spreads, the Portfolio
relied on a yield advantage from overweighting non-Treasury sectors to outpace
its benchmark.
  As we begin the new fiscal year, the Portfolio is positioned with moderately
greater interest rate sensitivity than its benchmark, and it is overweighted in
non-Treasury sectors. A calendar-year-end widening in asset backed security
spreads has led to increased exposure in that sector. The Portfolio continues
to maintain a high quality profile.

Benchmark U.S. Government Securities Portfolio
 
  With the crisis in Southeast Asia continuing to spread during the final
months of fiscal 1997, the U.S. bond market remained a primary recipient of
investment capital. This demand allowed yields on short-term government bonds
to return to near their lows of the past fiscal year. Throughout the year, bond
yields increased by as much as 1.0% on fears that strong economic growth would
cause the Federal Reserve to tighten monetary policy.
 
  However, moderately slower domestic growth coupled with investors' fears of a
world-wide financial meltdown caused the markets to re-evaluate the situation.
As foreign countries' restructuring plans and International Monetary Fund aid
came into focus, the need for any Federal Reserve action was delayed, and
currently no action is priced into the bond market over the next year. Five-
year government interest rates closed the fiscal year nearly unchanged in
yield, though they did trade within a range of 1.25% over the 12-month period.
 
  On an absolute basis, this range-bound move in rates caused the return on
government-bond funds to consist primarily of interest income. In this
environment, maintaining additional portfolio yield in the form of callable
agencies or mortgage-backed securities was a rewarding strategy. Thus, our
modest overweight to mortgage-backed securities was a source of incremental
positive performance. The Portfolio's performance moved in step with its
benchmark, as the generous "real yields" currently available in the bond market
have kept us fully invested in bonds.

BENCHMARK U.S. TREASURY INDEX PORTFOLIO
 
During the fiscal year ended November 30, 1997, Treasury rates changed only
marginally, rising in the first part of the year and falling in the latter
part. Two forces counteracted each other: A fast growing economy created fears
of a Federal Reserve tightening, while declines in actual measured inflation
and the secular deficit pushed rates lower. The yield curve flattened during
the year.
  As it seeks to do, the Benchmark U.S. Treasury Index Portfolio performed in
line with the Lehman Treasury Index. We will continue to pursue a passive
investment strategy by investing in securities that represent the Index. These
efforts seek to provide returns that closely track the returns of the Index.

Management's Discussion of Portfolio Performance

Benchmark Balanced Portfolio
 
The performance of the Benchmark Balanced Portfolio closely paralleled that of
its composite index for the fiscal year ending November 30, 1997. This was due
primarily to our positive stance on equities during the year as well as the
strong relative performance of both the equity and bond components of the
Portfolio.
  During the first half of the fiscal year, the emphasis within the Portfolio's
equity component remained on large-capitalization, multi-national issues. These
stocks were among the market leaders. But, as the market broadened mid year, we
expanded our equity reach to include several smaller- to mid-sized growth
issues that exhibited strong earnings growth potential. We continue to focus on
these stocks while maintaining a relatively low risk profile in the entire
equity portfolio.
  Bonds also contributed to our relative performance improvement. Throughout
the year, our slightly longer duration and our preference for corporate bonds
proved to be a successful strategy. As we enter a new fiscal year, this is a
strategy that we continue to implement.
  Overall, our enhanced risk control measures, with respect to asset allocation
and equity and bond management, contributed positively to performance over the
past 12 months. As the markets continue to exhibit unprecedented volatility and
uncertainty, we feel our diligence in managing risk will serve us well, both on
an absolute and relative basis.

MANAGEMENT'S DISCUSSION OF PORTFOLIO PERFORMANCE

BENCHMARK DIVERSIFIED GROWTH PORTFOLIO
 
The fiscal-year performance of the Benchmark Diversified Growth Portfolio was
very strong relative to other mutual funds in its peer group. The Portfolio's
performance lagged that of the broader market index for the period.

  Earlier in the year, we favored large-capitalization issues, which clearly
were the market leaders. Investors seemed to disregard the high absolute and
relative premiums that were being paid for many of these issues, and they
forced prices up accordingly. Later, though, we began to slowly move away from
these issues. In their place we selectively added several more mid-sized growth
issues that the market had largely ignored to that point. The Portfolio still
has exposure to many large-cap stocks, but it's now tilted toward domestically
oriented mid-sized growth companies, which we feel are attractively priced on a
relative valuation basis.

  Throughout the past year, we have been diligent in evaluating the individual
and portfolio risks associated with every investment we make. The performance
improvements we have made are due in part to this enhancement to our management
process. As the markets continue to exhibit unprecedented volatility and
uncertainty, we feel our diligence in managing risk will serve us well, both on
an absolute and relative basis.

BENCHMARK EQUITY INDEX PORTFOLIO
 
Performance from retail, capital goods and financial stocks had the greatest
impact on the total return of the S&P 500 Index for the fiscal year ended
November 30, 1997. The Index returned 28.52% for the period, outpacing small-
capitalization stocks, as measured by the Russell 2000 Index, by more than 5.3
percentage points.

  There were 30 additions and deletions to the Index during the 1997 fiscal
year. Some of the more notable changes included: the addition of State Street
following the completion of the merger between Nynex and Bell Atlantic; the
addition of Charles Schwab, which replaced Morgan Stanley; and the addition of
Health South Corp. in place of Boatman's Bancshares, which was acquired by
NationsBank.

  The Fund's slight underperformance relative to the S&P 500 Index was due
primarily to expenses.

  Going forward, we will continue to follow a passive strategy seeking to
provide returns that closely track those of the S&P 500 Index.

Benchmark Focused Growth Portfolio
 
Most large-capitalization domestic equity indexes registered strong fiscal-year
gains. Surpassing the performance of the S&P 500 Index once again proved to be
a difficult task for most money managers. While the Focused Growth Portfolio
did fall short of the S&P 500 for the period, we are happy to report that we
have made significant progress in the Portfolio's performance relative to its
peer group, and we are confident this momentum can continue.
  Throughout the year, we focused our attention on companies with a high degree
of earnings predictability. This is a theme that we believe will be even more
important in 1998, as earnings growth may become scarce, and higher relative
returns accrue to those companies that can deliver on their earnings forecasts.
  In the first part of the fiscal year, companies with predictable earnings
flow generally were large, multi-national firms, and the securities of these
companies dominated the Portfolio. Recently, volatility in the international
markets and earnings uncertainties for companies with foreign exposure have
caused us to tilt the Portfolio toward domestic, mid-sized growth companies. On
a relative valuation basis, we feel that many of these issues are attractively
priced.
  Throughout the year, we were diligent in evaluating the individual and
portfolio risks associated with every investment we made. The performance
improvements we have experienced are due in part to this management
enhancement. As the markets continue to exhibit unprecedented volatility and
uncertainty, we feel our diligence in managing risk will serve us well, both on
an absolute and relative basis.

Benchmark International Equity Index Portfolio
 
International stocks, as represented by the Europe Australia and Far East
(EAFE) Index, fell 0.40% for the 12 month period ended November 30, 1997,
trailing the U.S. market, represented by the S&P 500 Index, by almost 30
percentage points. Both Japan and Hong Kong fell nearly 24% for the fiscal
year, while most of the larger European markets posted gains. In the United
Kingdom, for example, the market was up 22%. The German market posted a 20%
gain, while France returned 9%.
  The Portfolio's performance surpassed that of the EAFE Index since commencing
investment operations in April 1997. We will practice a passive investment
strategy as we seek returns that approximate those of the international stock
market in general and the EAFE Index in particular.

Management's Discussion of Portfolio Performance

Benchmark International Growth Portfolio
 
In the first half of the fiscal year, falling interest rates, expectations for
robust earnings, a strong dollar and firm liquidity inflows fueled a powerful
global equity rally. By late summer, though, global financial markets appeared
overvalued and serious problems emerged in Southeast Asia and in the Japanese
financial system. As Thailand devalued its currency, a domino effect hit, with
every country in Asia, except Hong Kong, devaluing its currency. The Portfolio
had a diversified exposure to the Southeast Asian markets in modest proportions
early in the year, but by August 1997 we had eliminated this exposure.
  By fall it had become apparent that the problems in Southeast Asia were
spreading to northern Asia and other emerging markets. As a result, global
equity markets experienced corrections, with emerging markets the hardest hit.
The Portfolio was well prepared for this, as we had reduced the number of high
volatility stocks and lowered the Portfolio's emerging-market exposure.
  Recently, the focus has returned to Japan, where additional negative economic
news and a string of bankruptcies sent the market and the yen sharply lower.
Until early fall, the Portfolio held a modest underweight in Japan, but by late
October 1997 we further trimmed its exposure to the Japanese market and
increased its weighing in Europe, where strong exposure to financial stocks has
helped performance.
  This strategy helped the Portfolio outperform its benchmark index during the
fiscal year. In addition, our focus on high-quality growth stocks and
underweighted exposure to cyclical and commodity stocks helped increase the
Portfolio's fiscal-year performance.

BENCHMARK SMALL COMPANY INDEX
 
Small-capitalization stocks, as represented by the Russell 2000 Index, posted a
23.24% return for the fiscal year ended November 30, 1997. The Russell 2000
underperformed relative to the S&P 500 Index, which returned 28.52% for the
same period. The Portfolio is managed to closely track the performance of the
Russell 2000 Index after adjusting for expenses.
  The Russell 2000 Index represents the smaller two-thirds of the 3,000 largest
companies in the Russell 3000 Index. Companies leave the index as a result of
mergers, acquisitions and other events following the annual index
reconstitution in June. As of the end of November 1997, the Russell 2000 Index
included 1,919 companies. The market capitalization of companies in the index
ranged from $40 million to $2.5 billion, and the median company size was $463
million. The total market capitalization of the Russell 2000, after adjusting

*The Portfolio may purchase securities with delivery or payments to occur at a
later date. At the time the Portfolio enters into a commitment to purchase a
security, the transaction is recorded and the value of the security is
reflected in the net asset value. The value of the security may vary with
market fluctuations. No interest accrues to the Portfolio until payment takes
place. At the time the Portfolio enters into this type of transaction it is
required to segregate cash or other liquid assets at least equal to the value
of the securites purchased. At November 30, 1997, the Portfolio had a purchase
commitment outstanding of approximately $3,748 (8.1% of net assets), with a
corresponding amount of assets segregated.

NOTES TO FINANCIAL STATEMENTS
November 30, 1997
1. ORGANIZATION
The Benchmark Funds (the "Trust") is a Massachusetts business trust registered
under the Investment Company Act of 1940 (as amended) as an open-end
management investment company. The Trust includes seventeen portfolios, each
with its own investment objective. Each Portfolio, other than the
International Bond Portfolio, is classified as a diversified investment
company. The Northern Trust Company ("Northern") acts as the Trust's
investment adviser, transfer agent, and custodian. Goldman, Sachs & Co.
("Goldman Sachs") acts as the Trust's administrator and distributor. Presented
herein are the financial statements of the fixed income and equity portfolios
(the "Portfolios").
 Each of the Portfolios may issue four separate classes: Class A, B, C and D.
Each class is distinguished by the level of administrative support and
transfer agent service provided. As of November 30, 1997, Class A, Class C and
Class D units are outstanding for certain Portfolios.
 
2. SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of significant accounting policies consistently
followed by the Portfolios in the preparation of their financial statements.
These policies are in conformity with generally accepted accounting principles
("GAAP"). The presentation of financial statements in conformity with GAAP
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
(a) Investment Valuation
Investments held by a Portfolio are valued at the last quoted sale price on
the exchange on which such securities are primarily traded, or if any
securities are not traded on a valuation date, at the last quoted bid price.
Securities which are traded in the over-the-counter markets are valued at the
last quoted bid price. Exchange traded futures and options are valued at the
settlement price as established by the exchange on which they are traded.
Index futures are marked to market on a daily basis. Any securities, including
restricted securities, for which current quotations are not readily available
are valued at fair value as determined in good faith by Northern under the
supervision of the Board of Trustees ("Board"). Short-term investments are
valued at amortized cost which Northern has determined, pursuant to Board
authorization, approximates market value.
 
(b) Investment Transactions and Investment Income
Investment transactions are recorded as of the trade date. Realized gains and
losses on investment transactions are calculated on the identified-cost basis.
Interest income is recorded on the accrual basis and includes amortization of
discounts and premiums. The interest rates reflected in the Statements of
Investments represent either the stated coupon rate, annualized yield on date
of purchase for discount notes, the current reset rate for floating rate
securities or, for interest only or principal only securities, the current
effective yield. Dividend income is recorded on the ex-dividend date.
Dividends from foreign securities are recorded on the ex-date, or as soon as
the information is available.
 
(c) Repurchase Agreements
During the term of a repurchase agreement, the market value of the underlying
collateral, including accrued interest, is required to exceed the market value
of the repurchase agreement. The underlying collateral for all repurchase
agreements is held in a customer-only account of Northern, as custodian for
the Trust, at the Federal Reserve Bank of Chicago.
 
(d) Futures Contracts
Each Portfolio may invest in long or short futures contracts for hedging
purposes, to increase total return (i.e., for speculative purposes) or to
maintain liquidity. The Portfolios bear the market risk arising from changes
in the value of these financial instruments. At the time a Portfolio enters
into a futures contract it is required to make a margin deposit with the
custodian of a specified amount of liquid assets. Subsequently, as the market
price of the futures contract fluctuates, gains or losses are recorded and
payments are made, on a daily basis, between the portfolio and the broker. The
Statements of Operations reflect gains and losses as realized for closed
futures contracts and as unrealized for open futures contracts.
 At November 30, 1997, the Diversified Growth, Equity Index, Focused Growth
and Small Company Index Portfolios had entered into long exchange traded
futures contracts. The aggregate market value of assets pledged to cover
margin requirements for open positions at November 30, 1997 was approximately
$229,000, $1,433,000, $85,000, and $248,000 for the Diversified Growth, Equity
Index, Focused Growth and Small Company Index Portfolios, respectively.
 
(e) Options Contracts
Each Portfolio may purchase and write (sell) put and call options on foreign
and domestic stock indices, foreign

currencies, and U.S. and foreign securities that are traded on U.S. and
foreign securities exchanges and over-the-counter markets. These transactions
are for hedging (or cross-hedging) purposes or for the purposes of earning
additional income.
 The risk associated with purchasing an option is that the Portfolio pays a
premium whether or not the option is exercised. Additionally, the Portfolio
bears the risk of loss of premium and change in market value should the
counterparty not perform under the contract. Put and call options purchased
are accounted for in the same manner as Portfolio securities.
 The cost of securities acquired through the exercise of call options is
increased by the premiums paid. The proceeds from securities sold through the
exercise of put options are decreased by the premiums paid.
 In writing an option, the Portfolio bears the market risk of an unfavorable
change in the price of the security or currency underlying the written option.
Exercise of an option written by the Portfolio could result in the Portfolio
selling or buying a security or currency at a price different from the current
market value. Transactions in written call options for the year ended November
30, 1997 for the Portfolios were as follows:

</TABLE>
 
 The Portfolios did not write put options during the year ended November 30,
1997.
 
(f) Stripped Securities
Stripped securities represent the right to receive future interest payments
(interest only stripped securities) or principal payments (principal only
stripped securities). The value of variable rate interest only stripped
securities varies directly with changes in interest rates, while the value of
fixed rate interest only securities and the value of principal only stripped
securities vary inversely with changes in interest rates.
 
(g) Forward Foreign Currency Exchange Contracts
Certain Portfolios are authorized to enter into forward foreign currency
exchange contracts for the purchase of a specific foreign currency at a fixed
price on a future date as a hedge or cross-hedge against either specific
transactions or portfolio positions. In addition, the International Bond and
International Growth Portfolios may enter into foreign currency exchange
contracts for speculative purposes. The objective of a Portfolio's foreign
currency hedging transactions is to reduce the risk that the U.S. dollar value
of the Portfolio's foreign currency denominated securities will decline in
value due to changes in foreign currency exchange rates. All forward foreign
currency contracts are "marked-to-market" daily at the applicable exchange
rates and any resulting unrealized gains or losses are recorded in the
financial statements. The Portfolio records realized gains or losses when the
forward contract is offset by entry into a closing transaction or extinguished
by delivery of the currency. Risks may arise upon entering into these
contracts from the potential inability of counterparties to meet the terms of
their contracts and from unanticipated movements in the value of a foreign
currency relative to the U.S. dollar.
 The contractual amounts of forward foreign currency exchange contracts do not
necessarily represent the amounts potentially subject to risk. The measurement
of the risks associated with these instruments is meaningful only when all
related and offsetting transactions are considered.
 At November 30, 1997, there were no outstanding forward foreign currency
exchange contracts.
 
(h) Foreign Currency Translations
Values of investments denominated in foreign currencies are converted into
U.S. dollars using the spot market rate of exchange at the time of valuation.
Cost of purchases and proceeds from sales of investments, interest and
dividend income are translated into U.S. dollars using the spot market rate of
exchange prevailing on the respective dates of such transactions.
 The gains or losses on investments resulting from changes in foreign exchange
rates are included with net realized and unrealized gain (loss) on
investments.
 
(i) 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 of its taxable income and capital gains to its
unitholders. Therefore, no provision is made for federal taxes.
 At November 30, 1997, the Portfolios had approximately the following amounts
of capital loss carryforwards for U.S. federal tax purposes:

(k) Expenses
Expenses arising in connection with a specific Portfolio are allocated to that
Portfolio. Certain expenses arising in connection with a class of units are
allocated to that class of units. Expenses incurred which do not specifically
relate to an individual Portfolio are allocated among the Portfolios based on
each Portfolio's relative net assets.
 
(l) Distributions
Dividends from net investment income are declared and paid as follows:

 Each Portfolio's net realized capital gains are distributed at least
annually. Income dividends and capital gain distributions are determined in
accordance with income tax regulations. Such amounts may differ from income
and capital gains recorded in accordance with generally accepted accounting
principles.
 Distributions of short-term and long-term capital gains were declared and
paid December 22, 1997 to unitholders of record on December 19, 1997, as

 These reclassifications had no impact on the net asset value of the
Portfolios and are designed to present those Portfolios' capital accounts on a
tax basis.
 
3. ADVISORY, TRANSFER AGENCY AND CUSTODIAN AGREEMENTS
The Trust has an investment advisory agreement with Northern whereby each
Portfolio pays Northern a fee, computed daily and payable monthly, based on a
specified percentage of its average daily net assets. For the current fiscal
year, Northern voluntarily agreed to waive a portion of the advisory fees as
shown on the accompanying Statements of Operations. The annual advisory fees
and waiver rates expressed as a percentage of average daily net assets for the
year ended November 30, 1997, are as follows:

 As compensation for the services rendered as transfer agent, including the
assumption by Northern of the expenses related thereto, Northern receives a
fee, computed daily and payable monthly, at an annual rate of .01%, .05%, .10%
and .15% of the average daily net asset value of the outstanding Class A, B, C
and D units, respectively, for the Portfolios.
 
4. ADMINISTRATION AND DISTRIBUTION AGREEMENTS
The Trust has an administration agreement (as amended May 1, 1997) with
Goldman Sachs whereby each Portfolio pays the Administrator a fee, computed
daily and payable monthly, at an annual rate of .10% of the Portfolio's
average daily net assets, except the International Bond, International Equity
Index and International Growth Portfolios which pay the Administrator a fee,
computed daily and payable monthly, at an annual rate of .15% of their
respective average daily net assets.
 In addition, if in any fiscal year the sum of a Portfolio's expenses,
including the administration fee, but excluding the investment advisory fee
and transfer agency fee payable to Northern pursuant to its agreements with
the Trust, servicing fees, and extraordinary expenses (such as taxes, interest
and indemnification expenses), exceeds on an annualized basis .10% of a
Portfolio's average daily net assets (0.25% for International Growth
Portfolio, International Bond Portfolio and International Equity Index
Portfolio), Goldman Sachs will reimburse each Portfolio for the amount of the
excess pursuant to the terms of the administration agreement.
 Prior to May 1, 1997 each Portfolio paid the Administrator a fee, computed
daily and payable monthly, based on the average daily net assets of each
Portfolio at the rates set forth below:
 
<TABLE>
<CAPTION>
Average net assets                Rate

For net assets over $750,000,000  .050
- ---------------------------------------
</TABLE>
 
 Prior to May 1, 1997, Goldman Sachs also voluntarily agreed to limit
administration fees to .10% of average daily net assets for each Portfolio. In
addition, Goldman Sachs agreed to waive a portion of its administrative fees
should overall administration fees earned during the preceding year exceed
certain specified levels. No waiver was required under this agreement during
the year ended November 30, 1997. Furthermore, Goldman Sachs voluntarily
agreed to reimburse each Portfolio for certain expenses in the event that such
expenses, as defined, exceed on an annualized basis .10% of its average daily
net assets for such fiscal year for the Bond, Short-Intermediate Bond, U.S.
Government Securities, U.S. Treasury Index, Balanced, Diversified Growth,
Equity Index, Focused Growth and Small Company Index Portfolios and .25% of
the average daily net assets for such fiscal year for the International Bond,
International Equity Index and International Growth Portfolios.
 The administration fees waived and expenses reimbursed during the year ended
November 30, 1997 are shown on the accompanying Statements of Operations.
 Goldman Sachs receives no compensation under the distribution agreement.
 
5. UNITHOLDER SERVICING PLAN
The Trust has adopted a Unitholder Servicing Plan pursuant to which the Trust
may enter into agreements with institutions or other financial intermediaries
under which they will render certain unitholder administrative support
services for their customers or other investors who beneficially own Class B,
C and D units. As compensation under the Unitholder Servicing Plan, the
institution or other financial intermediary receives a fee at an annual rate
of up to .10%, .15% and .25% of the average daily net asset value of the
outstanding Class B, C and D units, respectively.

REPORT OF INDEPENDENT AUDITORS
 
 
To the Unitholders and Trustees of
The Benchmark Funds
Fixed Income and Equity Portfolios
 
We have audited the accompanying statements of assets and liabilities, including
the statements of investments, of the Bond, Intermediate Bond, International
Bond, Short-Intermediate Bond, U.S. Government Securities, U.S. Treasury Index,
Balanced, Diversified Growth, Equity Index, Focused Growth, International Equity
Index, International Growth and Small Company Index Portfolios, comprising the
Fixed Income and Equity Portfolios of The Benchmark Funds, as of November 30,
1997, and the related statements of operations, changes in net assets and
financial highlights for the periods indicated therein. These financial
statements and financial highlights are the responsibility of the Portfolios'
management. Our responsibility is to express an opinion on these financial
statements and 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 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. Our procedures included verification of the investments owned at
November 30, 1997 by physical examination of the securities held by the
custodian and by correspondence with central depositories, unaffiliated
subcustodian banks 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 the
Bond, Intermediate Bond, International Bond, Short-Intermediate Bond, U.S.
Government Securities, U.S. Treasury Index, Balanced, Diversified Growth, Equity
Index, Focused Growth, International Equity Index, International Growth and
Small Company Index Portfolios, comprising the Fixed Income and Equity
Portfolios of The Benchmark Funds, at November 30, 1997, the results of their
operations, the changes in their net assets and financial highlights for the
periods indicated therein, in conformity with generally accepted accounting
principles.

This Prospectus describes the Service Class of shares ("Service Shares" or
"shares") of four short-term money market portfolios (the "Portfolios") offered
by The Benchmark Funds (the "Trust") to institutional investors. Each
Portfolio, other than the Tax-Exempt Portfolio, seeks to maximize current
income to the extent consistent with the preservation of capital and
maintenance of liquidity. The Tax-Exempt Portfolio seeks to provide, to the
extent consistent with the preservation of capital and prescribed portfolio
standards, a high level of income exempt from regular Federal income tax.     
 
  The GOVERNMENT SELECT PORTFOLIO invests in selected short-term obligations
  of the U.S. Government, its agencies and instrumentalities the interest on
  which is generally exempt from state income taxation.
 
  The GOVERNMENT PORTFOLIO invests in short-term obligations of the U.S.
  Government, its agencies and instrumentalities and related repurchase
  agreements.
 
  The DIVERSIFIED ASSETS PORTFOLIO invests in money market instruments of
  both U.S. and foreign issuers, including certificates of deposit, bankers'
  acceptances, commercial paper and repurchase agreements.
 
  The TAX-EXEMPT PORTFOLIO invests primarily in short-term municipal
  instruments the interest on which is exempt from regular Federal income
  tax.
 
Each Portfolio is advised by The Northern Trust Company ("Northern"). Shares
are sold and redeemed without any purchase or redemption charge imposed by the
Trust, although Northern and other institutions may charge their customers for
services provided in connection with their investments.

DESCRIPTION OF TRUST
 
The Trust is an open-end, management investment company registered under the
Investment Company Act of 1940 (the "1940 Act"). Each Portfolio consists of a
separate pool of assets with separate investment policies, as described below
under "Investment Information." All of the Portfolios are classified as
diversified companies. Northern serves as investment adviser, transfer agent
and custodian. Goldman Sachs serves as distributor and administrator.
 
Shares of the Portfolios are offered exclusively to institutional investors.
See "Investing--Purchase of Service Shares" and "Investing--Redemption of
Service Shares" for information on how to place purchase and redemption orders.
 
Each Portfolio seeks to maintain a net asset value of $1.00 per share. The
assets of each Portfolio will be invested in dollar-denominated debt securities
with remaining maturities of thirteen months or less as defined by the
Securities and Exchange Commission (the "SEC"), and each Portfolio's dollar-
weighted average portfolio maturity will not exceed 90 days. All securities
acquired by the Portfolios will be determined by Northern, under guidelines
established by the Trust's Board of Trustees, to present minimal credit risks,
and will be "Eligible Securities" as defined by the SEC. There can be no
assurance that the Portfolios will be able to achieve a stable net asset value
on a continuous basis, or that they will achieve their investment objectives.
 
Investors should note that one or more of the Portfolios may purchase variable
and floating rate instruments, enter into repurchase agreements, reverse
repurchase agreements and securities loans, acquire U.S. dollar-denominated
instruments of foreign issuers and make limited investments in illiquid
securities and securities issued by other investment companies. These
investment practices involve investment risks of varying degrees. None of the
Portfolios will invest in instruments denominated in a foreign currency.
 
SUMMARY OF EXPENSES
 
The following table sets forth the estimated annualized operating expenses for
Service Shares of the Portfolios for the current fiscal year. Hypothetical
examples based on the table are also shown.

expenses on a hypothetical $1,000 investment in Service Shares assuming a 5%
annual return and redemption at the end of each time period:

(1) "Other Expenses" include the payment of a fee to Northern, Goldman Sachs or
    other institutions under the service plan equal to .08% of the average
    daily net asset value of the Service Shares. See "Trust Information--
    Service Plan" for additional information.     
   
The information with respect to Service Shares is estimated and reflects the
expenses each Portfolio expects to incur with respect to such Shares during the
current fiscal year. The expense information included in the table and the
hypothetical example above relate only to Service Shares (the class offered by
this Prospectus) and should not be considered as representative of past or
future performance. During the Trust's last fiscal year, Northern voluntarily
reduced its advisory fee for the Government Select Portfolio (payable at the
annual rate of .25% of the Portfolio's average daily net assets) to .10% per
annum. For the fiscal period December 1, 1996 through April 30, 1997, Goldman
Sachs charged an administration fee with respect to each Portfolio during such
period at the annual rate of .25% of the first $100 million, .15% of the next
$200 million, .075% of the next $450 million and .05% of any excess over $750
million of the Portfolio's average daily net assets. For the period May 1, 1997
through November 30, 1997, Goldman Sachs was entitled to an administration fee
equal to .10% of the average daily net assets of each Portfolio. In addition,
during the fiscal year, Goldman Sachs reimbursed each Portfolio's expenses
(including the fees payable to Goldman Sachs as administrator, but excluding
the fees payable to Northern for its duties as adviser and certain
extraordinary expenses) which exceeded on an annualized basis .10% of the
Portfolio's average daily net assets for such fiscal year. On April 1, 1998,
upon the offering of the Portfolios' Service Shares and Premier Shares, Goldman
Sachs will reimburse each Portfolio's expenses (including fees payable to
Goldman Sachs as administrator, but     
 
                                       4

excluding the fees payable to Northern for its duties as adviser and transfer
agent, payments under the service plan for the Portfolios' Premier Shares and
Service Shares and certain extraordinary expenses) which exceed on an
annualized basis .10% of the Portfolio's average daily net assets. Without the
undertakings of Northern and Goldman Sachs, "Other Expenses" of the Government
Select, Government, Diversified Assets and Tax-Exempt Portfolios would be .22%,
 .20%, .19% and .22%, respectively; and "Total Operating Expenses" of the
Government Select, Government, Diversified Assets and Tax-Exempt Portfolios
would be .73%, .71%, .70% and .73%, respectively. For a more complete
description of the Portfolios' expenses, see "Trust Information" in this
Prospectus.

THE PURPOSE OF THE FOREGOING TABLE IS TO ASSIST YOU IN UNDERSTANDING THE
VARIOUS SHAREHOLDER TRANSACTION AND OPERATING EXPENSES OF EACH PORTFOLIO THAT
SHAREHOLDERS BEAR DIRECTLY OR INDIRECTLY. IT DOES NOT, HOWEVER, REFLECT ANY
CHARGES WHICH MAY BE IMPOSED BY NORTHERN, ITS AFFILIATES AND CORRESPONDENT
BANKS AND OTHER INSTITUTIONS ON THEIR CUSTOMERS AS DESCRIBED UNDER "INVESTING--
PURCHASE OF SERVICE SHARES." THE EXAMPLE SHOWN ABOVE SHOULD NOT BE CONSIDERED A
REPRESENTATION OF PAST OR FUTURE EXPENSES OR RATE OF RETURN. ACTUAL EXPENSES
AND RATE OF RETURN MAY BE MORE OR LESS THAN THOSE SHOWN.

                             INVESTMENT INFORMATION
 
The investment objective of each Portfolio, other than the Tax-Exempt
Portfolio, is to seek to maximize current income to the extent consistent with
the preservation of capital and maintenance of liquidity by investing
exclusively in high quality money market instruments. The Tax-Exempt Portfolio
seeks to provide its 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 investment objective of a Portfolio may not be changed without
the vote of the majority of the outstanding shares of the particular Portfolio
(as defined below under "Organization"). Except as expressly noted below,
however, a Portfolio's investment policies may be changed without a vote of
shareholders.
   
All securities acquired by the Portfolios will be determined by Northern, under
guidelines established by the Board of Trustees, to present minimal credit
risks and will be "Eligible Securities" as defined by the SEC. Eligible
Securities include, generally, (i) securities that either (a) have short-term
debt ratings at the time of purchase in the two highest rating categories by at
least two unaffiliated nationally recognized statistical rating organizations
("NRSROs") (or one NRSRO if the security is rated by only one NRSRO), or (b)
are issued or guaranteed by persons with such ratings, and (ii) securities that
are unrated (including securities of issuers that have long-term but not short-
term ratings) but are determined to be of comparable quality. Securities that
are in the highest short-term rating category as described above (and unrated
securities determined to be of comparable quality) are designated "First Tier
Securities." Under normal circumstances, the Government Select, Government and
Diversified Assets Portfolios intend to limit purchases of securities to First
Tier Securities. The Additional Statement includes a description of applicable
NRSRO ratings.     
 
Each Portfolio is managed so that the average maturity of all instruments in
the Portfolio (on a dollar-weighted basis) will not exceed 90 days. In no event
will the Portfolios purchase any securities which mature more than 13 months
from the date of purchase (except for certain variable and floating rate
instruments and securities collateralizing repurchase agreements). Securities
in which the Portfolios invest may not earn as high a level of income as long-
term or lower quality securities, which generally have greater market risk and
more fluctuation in market value.
 
GOVERNMENT SELECT PORTFOLIO
   
The Government Select Portfolio seeks to achieve its investment objective by
investing exclusively in securities issued or guaranteed as to principal and
interest by the U.S. Government, its agencies or instrumentalities. In making
investments, Northern will seek to acquire, under normal market conditions,
only those U.S. Government securities the interest on which is generally exempt
from state income taxation. Securities generally eligible for this exemption
include those issued by the U.S. Treasury and certain U.S. Government agencies
and instrumentalities, including the Federal Home Loan Bank and the Federal
Farm Credit Banks Funding Corp. The Portfolio intends to limit investments to
exempt U.S. Government securities. However, under extraordinary circumstances,
such as when appropriate exempt securities are unavailable, the Portfolio may
make investments in non-exempt U.S. Government securities and cash equivalents,
and may hold uninvested cash. See "Investing--Taxes" below for certain tax
considerations.     
 
 
                                       6
<PAGE>
 
GOVERNMENT PORTFOLIO
 
The Government Portfolio seeks to achieve its investment objective by investing
exclusively in:
     
  (A) Marketable securities issued or guaranteed as to principal and interest
  by the U.S. Government or by any of its agencies or instrumentalities and
  custodial receipts with respect thereto; and     
 
  (B) Repurchase agreements relating to the above instruments.
 
DIVERSIFIED ASSETS PORTFOLIO
 
In pursuing its investment objective, the Diversified Assets Portfolio may
invest in a broad range of government, bank and commercial obligations that are
available in the money markets. In particular, the Portfolio may invest in:
 
  (A) U.S. dollar-denominated obligations of U.S. banks with total assets in
  excess of $1 billion (including obligations of foreign branches of such
  banks);
 
  (B) U.S. dollar-denominated obligations of foreign commercial banks where
  such banks have total assets in excess of $5 billion;
 
  (C) High quality commercial paper and other obligations issued or
  guaranteed by U.S. and foreign corporations and other issuers rated (at the
  time of purchase) A-2 or higher by Standard & Poor's Ratings Group ("S&P"),
  Prime-2 or higher by Moody's Investors Service, Inc. ("Moody's"), Duff 2 or
  higher by Duff & Phelps Credit Rating Co. ("D&P"), F-2 or higher by Fitch
  IBCA, Inc. ("Fitch") or TBW-2 or higher by Thomson BankWatch, Inc. ("TBW");
 
  (D) Rated and unrated corporate bonds, notes, paper and other instruments
  that are of comparable quality to the commercial paper permitted to be
  purchased by the Portfolio;
 
  (E) Asset-backed securities (including interests in pools of assets such as
  mortgages, installment purchase obligations and credit card receivables);
 
  (F) Securities issued or guaranteed as to principal and interest by the
  U.S. Government or by its agencies or instrumentalities and custodial
  receipts with respect thereto;
     
  (G) U.S. dollar-denominated securities issued or guaranteed by one or more
  foreign governments or political subdivisions, agencies or
  instrumentalities thereof;     
 
  (H) Repurchase agreements relating to the above instruments; and
 
  (I) Securities issued or guaranteed by state or local governmental bodies.
 
TAX-EXEMPT PORTFOLIO
 
The Tax-Exempt Portfolio invests primarily in high quality short-term
instruments, the interest on which is, in the opinion of bond counsel for the
issuers, exempt from regular Federal income tax ("Municipal Instruments"). Such
opinions may contain various assumptions, qualifications or exceptions that are
reasonably acceptable to Northern. In particular, the Portfolio may invest in:
 
  (A) Fixed and variable rate notes and similar debt instruments rated MIG-2,
  VMIG-2 or Prime-2 or higher by Moody's, SP-2 or A-2 or higher by S&P, AA or
  higher by D&P or F-2 or higher by Fitch;
 
                                       7
<PAGE>
 
  (B) Tax-exempt commercial paper and similar debt instruments rated Prime-2
  or higher by Moody's, A-2 or higher by S&P, Duff 2 or higher by D&P or F-2
  or higher by Fitch;
 
  (C) Rated and unrated municipal bonds, notes, paper or other instruments
  that are of comparable quality to the tax-exempt commercial paper permitted
  to be purchased by the Portfolio; and
 
  (D) Municipal bonds and notes which are guaranteed as to principal and
  interest by the U.S. Government or an agency or instrumentality thereof or
  which otherwise depend directly or indirectly on the credit of the United
  States.
 
As a matter of fundamental policy, changeable only with the approval of the
holders of a majority of the outstanding shares of the Tax-Exempt Portfolio, at
least 80% of the Portfolio's annual gross income will be derived from Municipal
Instruments except under extraordinary circumstances, such as when Northern
believes that market conditions indicate that the Portfolio should adopt a
temporary defensive posture by holding uninvested cash or investing in taxable
short-term securities ("Taxable Investments"). Taxable Investments will consist
exclusively of instruments that may be purchased by the Diversified Assets
Portfolio.
 
DESCRIPTION OF SECURITIES AND COMMON INVESTMENT TECHNIQUES
 
BANK OBLIGATIONS. Domestic and foreign bank obligations in which the
Diversified Assets Portfolio may invest include certificates of deposit, bank
and deposit notes, bankers' acceptances and fixed time deposits. Such
obligations may be general obligations of the parent bank or may be limited to
the issuing branch or subsidiary by the terms of the specific obligation or by
government regulation. Total assets of a bank are determined on the basis of
the bank's most recent annual financial statements.
   
FOREIGN OBLIGATIONS. In addition to the obligations of foreign commercial banks
and foreign branches of U.S. banks, the Diversified Assets Portfolio may
acquire commercial obligations issued by Canadian corporations and Canadian
counterparts of U.S. corporations, as well as Europaper, which is U.S. dollar-
denominated commercial paper of a foreign issuer. The Diversified Assets
Portfolio may also invest in obligations issued or guaranteed by one or more
foreign governments or any of their political subdivisions, agencies or
instrumentalities. Such obligations may include debt obligations of
supranational entities, including international organizations (such as the
European Coal and Steel Community and the International Bank for Reconstruction
and Development (also known as the World Bank)) designated or supported by
governmental entities to promote economic reconstruction or development and
international banking institutions and related government agencies. Investments
by the Diversified Assets Portfolio in foreign issuer obligations will not
exceed 50% of the Portfolio's total assets measured at the time of purchase.
    
Obligations of foreign issuers acquired by the Diversified Assets Portfolio may
involve risks that are different than those of obligations of domestic issuers.
These risks include unfavorable political and economic developments, the
possible imposition of withholding taxes on interest income, possible seizure
or nationalization of foreign deposits, the possible establishment of exchange
controls, or the adoption of other foreign governmental restrictions which
might adversely affect the payment of principal and interest on such
obligations. In addition, foreign branches of U.S. banks and foreign banks may
be subject to less stringent reserve requirements and to different accounting,
auditing, reporting, and recordkeeping standards than those applicable to
domestic branches of U.S. banks and, generally, there may be less publicly
available information
 
                                       8
<PAGE>
 
regarding such issuers. The Trust could also encounter difficulties in
obtaining or enforcing a judgment against a foreign issuer (including a foreign
branch of a U.S. bank).
   
VARIABLE AND FLOATING RATE INSTRUMENTS. The Portfolios may purchase rated and
unrated variable and floating rate instruments, which may have stated
maturities in excess of the Portfolios' maturity limitations subject to
applicable SEC regulations. In the case of the Diversified Assets Portfolio,
such instruments may include variable amount master demand notes that permit
the indebtedness thereunder to vary in addition to providing for periodic
adjustments in the interest rate. Unrated variable and floating rate
instruments will be determined by Northern to be of comparable quality at the
time of the purchase to rated instruments purchasable by the Portfolios. The
absence of an active secondary market with respect to particular variable and
floating rate instruments could, however, make it difficult for a Portfolio to
dispose of the instruments if the issuer defaulted on its payment obligation or
during periods that the Portfolio is not entitled to exercise its demand
rights, and the Portfolio could, for these or other reasons, suffer a loss with
respect to such instruments. Variable and floating rate instruments held by a
Portfolio will be subject to the Portfolio's 10% limitation on illiquid
investments when the Portfolio may not demand payment of the principal amount
within seven days and a reliable trading market is absent.     
   
UNITED STATES GOVERNMENT OBLIGATIONS. Each Portfolio may invest in a variety of
U.S. Treasury obligations, consisting of bills, notes and bonds, which
principally differ only in their interest rates, maturities and time of
issuance. These obligations include "stripped" securities issued by the U.S.
Treasury and recorded in the Federal Reserve book-entry record-keeping system.
The Portfolios may also invest in other securities issued or guaranteed by the
U.S. Government, its agencies and instrumentalities. Obligations of certain
agencies and instrumentalities, such as the Government National Mortgage
Association, are supported by the full faith and credit of the U.S. Treasury;
others, such as those of the Export-Import Bank of the United States, are
supported by the right of the issuer to borrow from the Treasury; others, such
as those of the Federal National Mortgage Association, are supported by the
discretionary authority of the U.S. Government to purchase the agency's
obligations; still others are supported only by the credit of the
instrumentalities. No assurance can be given that the U.S. Government would
provide financial support to its agencies or instrumentalities if it is not
obligated to do so by law. There is no assurance that these commitments will be
undertaken or complied with in the future.     
 
Securities guaranteed as to principal and interest by the U.S. Government, its
agencies 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 or an agency or instrumentality thereof,
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.
 
CUSTODIAL RECEIPTS FOR TREASURY SECURITIES. The Portfolios (other than the
Government Select Portfolio) may also purchase participations in trusts that
hold U.S. Treasury securities (such as TIGRs and CATS) where the trust
participations evidence ownership in either the future interest payments or the
future principal payments on the U.S. Treasury obligations. These
participations are normally issued at a discount to their "face value," and may
exhibit greater price volatility than ordinary debt securities because of the
manner in which their principal and interest are returned to investors.
Investments by the Government Portfolio in such custodial receipts will not
exceed 35% of the value of that Portfolio's total assets.
 
                                       9
<PAGE>
 
REPURCHASE AGREEMENTS. Each Portfolio may, in accordance with its investment
objective, policies and guidelines established by the Trust's Board of
Trustees, agree to purchase portfolio securities from financial institutions
subject to the seller's agreement to repurchase them at a mutually agreed upon
date and price ("repurchase agreements"). Although the securities subject to a
repurchase agreement may bear maturities exceeding 13 months, settlement for
the repurchase agreement will never be more than one year after a Portfolio's
acquisition of the securities and normally will be within a shorter period of
time. Securities subject to repurchase agreements are held either by the
Trust's custodian or subcustodian (if any), or in the Federal Reserve/Treasury
Book-Entry System. The seller under a repurchase agreement will be required to
maintain the value of the securities subject to the agreement in an amount
exceeding the repurchase price (including accrued interest). Default by the
seller would, however, expose a Portfolio to possible loss because of adverse
market action or delay in connection with the disposition of the underlying
obligations.
   
REVERSE REPURCHASE AGREEMENTS. The Government Select, Government and
Diversified Assets Portfolios may enter into reverse repurchase agreements
which involve the sale of money market securities held by a Portfolio, with an
agreement to repurchase the securities at an agreed upon price (including
interest) and date. A Portfolio will use the proceeds of reverse repurchase
agreements to purchase other money market securities either maturing, or under
an agreement to resell, at a date simultaneous with or prior to the expiration
of the reverse repurchase agreement. A Portfolio will utilize reverse
repurchase agreements, which may be viewed as borrowings (or leverage) by the
Portfolio, when it is anticipated that the interest income to be earned from
the investment of the proceeds of the transaction is greater than the interest
expense of the reverse repurchase transaction. During the time a reverse
repurchase agreement is outstanding, the Portfolio will segregate liquid assets
having a value at least equal to the repurchase price. A Portfolio may enter
into reverse repurchase agreements with banks, brokers and dealers, and has the
authority to enter into reverse repurchase agreements in amounts not exceeding
in the aggregate one-third of the Portfolio's total assets. See "Additional
Investment Information--Investment Restrictions" in the Additional Statement.
    
SECURITIES LENDING. The Portfolios may seek additional income from time to time
by lending their portfolio securities on a short-term basis to banks, brokers
and dealers under agreements requiring that the loans be secured by collateral
in the form of cash, cash equivalents or U.S. Government securities or
irrevocable bank letters of credit maintained on a current basis equal in value
to at least the market value of the securities loaned. A Portfolio may not make
such loans in excess of 33 1/3% of the value of the Portfolio's total assets
(including the loan collateral). Loans of securities involve risks of delay in
receiving additional collateral or in recovering the securities loaned, or
possibly loss of rights in the collateral should the borrower of the securities
become insolvent.
   
FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES. Each Portfolio may purchase
when-issued securities and make contracts to purchase or sell securities for a
fixed price at a future date beyond customary settlement time. Securities
purchased 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. Conversely, securities sold on a delayed-delivery or forward
commitment basis involve the risk that the value of the security to be sold may
increase prior to the settlement date. A Portfolio is required to segregate
liquid assets until three days prior to the settlement date, having a value
(determined daily) at least equal to the amount of the Portfolio's purchase
commitments, or to otherwise cover its position. Although a Portfolio would
generally purchase securities on a when-issued or forward     
 
                                       10
<PAGE>
 
commitment basis with the intention of acquiring securities, the Portfolio may
dispose of a when-issued security or forward commitment prior to settlement if
Northern deems it appropriate to do so.
   
INVESTMENT COMPANIES. In connection with the management of their daily cash
positions, the Portfolios may invest in securities issued by other investment
companies which invest in short-term, high-quality debt securities and which
determine their net asset value per share based on the amortized cost or penny-
rounding method of valuation ("money market funds"), and may invest in
securities issued by other types of investment companies consistent with their
investment objectives and policies. Investments by a Portfolio in other money
market funds and investment companies will be subject to the limitations of the
1940 Act as described in more detail in the Additional Statement. Although the
Portfolios do not expect to do so in the forseeable future, each Portfolio is
authorized to invest substantially all of its assets in a single open-end
investment company or series thereof with substantially the same investment
objective, policies and fundamental restrictions as the Portfolio. As a
shareholder of another investment company, a Portfolio would bear, along with
other shareholders, its pro rata portion of the other investment company's
expenses, including advisory fees. These expenses would be in addition to the
advisory fees and other expenses the Portfolio bears directly in connection
with its own operations. The Trust has been advised by its counsel that exempt-
interest dividends received by the Tax-Exempt Portfolio as a shareholder of a
regulated investment company paying such dividends will receive the same
Federal tax treatment as interest received by the Portfolio on Municipal
Instruments held by it.     
 
MUNICIPAL AND RELATED INSTRUMENTS. Municipal Instruments in which the Tax-
Exempt Portfolio may invest include debt obligations issued by or on behalf of
states, territories and possessions of the United States and their political
subdivisions, agencies, authorities and instrumentalities.
 
Municipal Instruments may be issued to obtain funds for various public
purposes, including capital improvements, the refunding of outstanding
obligations, general operating expenses, and lending to other public agencies.
Among other instruments, the Portfolio may purchase short-term Tax Anticipation
Notes, Bond Anticipation Notes, Revenue Anticipation Notes, and other forms of
short-term loans. Such notes are issued with a short-term maturity in
anticipation of the receipt of tax funds, the proceeds of bond placements or
other revenues.
 
Municipal Instruments include both "general" and "revenue" obligations. General
obligations are secured by the issuer's pledge of its full faith, credit and
taxing power for the payment of principal and interest. Revenue obligations are
payable only 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 such as lease payments from the user of the facility
being financed. Industrial development bonds are in most cases revenue
securities and are not payable from the unrestricted revenues of the issuer.
Consequently, the credit quality of an industrial revenue bond is usually
directly related to the credit standing of the private user of the facility
involved.
 
The Tax-Exempt Portfolio may also invest in "moral obligation" bonds, which are
normally issued by special purpose public authorities. If the issuer of a moral
obligation bond is unable to meet its debt service obligations from current
revenues, it may draw on a reserve fund, the restoration of which is a moral
commitment but not a legal obligation of the state or municipality which
created the issuer.
 
 
                                       11
<PAGE>
 
Municipal bonds with a series of maturity dates are called Serial Bonds. The
Portfolio may purchase Serial Bonds and other long-term securities provided
that they have a remaining maturity meeting the Tax-Exempt Portfolio's maturity
requirements. The Portfolio may also purchase long-term variable and floating
rate bonds (sometimes referred to as "Put Bonds") where the Portfolio obtains
at the time of purchase the right to put the bond back to the issuer or a third
party at par at least every thirteen months. Put Bonds with conditional puts
(that is, puts which cannot be exercised if the issuer defaults on its payment
obligations) will present risks that are different than those of other
Municipal Instruments because of the possibility that the Portfolio might hold
a long-term Put Bond on which a default occurs following its acquisition by the
Portfolio.
 
The Tax-Exempt Portfolio may acquire securities in the form of custodial
receipts evidencing rights to receive a specific future interest payment,
principal payment or both on certain municipal obligations. 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,"
"Municipal Certificates of Accrual on Tax-Exempt Securities" ("M-CATS") and
"Municipal Zero-Coupon Receipts." The Portfolio may also purchase certificates
of participation that, in the opinion of counsel to the issuer, are exempt from
regular Federal income tax. Certificates of participation are a type of
floating or variable rate obligation that represents interests in a pool of
municipal obligations held by a bank.
 
The Tax-Exempt Portfolio may acquire "standby commitments" with respect to the
Municipal Instruments it holds. Under a standby commitment, a dealer agrees to
purchase at the Portfolio's option specified Municipal Instruments at a
specified price. The acquisition of a standby commitment may increase the cost,
and thereby reduce the yield, of the Municipal Instruments to which the
commitment relates. The Portfolio will acquire standby commitments solely to
facilitate portfolio liquidity and does not intend to exercise its rights
thereunder for trading purposes.
 
Municipal Instruments purchased by the Tax-Exempt Portfolio may be backed by
letters of credit or other forms of credit enhancement issued by foreign (as
well as domestic) banks and other financial institutions. The credit quality of
these banks and financial institutions could, therefore, cause loss to a
Portfolio that invests in Municipal Instruments. Letters of credit and other
obligations of foreign financial institutions may involve certain risks in
addition to those of domestic obligations. (See "Foreign Obligations" above.)
   
As stated, the Tax-Exempt Portfolio expects to invest primarily in Municipal
Instruments. However, the Portfolio may from time to time hold uninvested cash
or invest a portion of its assets in Taxable Investments. The Portfolio does
not intend to invest more than 25% of the value of its total assets 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. The Portfolio may, however, invest 25% or more
of its total assets in (a) Municipal Instruments the interest upon which is
paid solely from revenues of similar projects, and (b) industrial development
obligations. In addition, although the Tax-Exempt Portfolio does not expect to
do so during normal market conditions, it may invest more than 25% of the value
of its total assets in Municipal Instruments whose issuers are in the same
state. When a substantial percentage of the Portfolio's assets is invested in
instruments which are used to finance facilities involving a particular
industry, whose issuers are in the same state or which are otherwise related,
there is a possibility that an economic, business or political development
affecting one such instrument would likewise affect the other related
instruments.     
 
 
                                       12
<PAGE>
 
   
So long as other suitable Municipal Instruments are available for investment,
the Tax-Exempt Portfolio does not intend to invest in "private activity bonds"
the interest from which may be treated as an item of tax preference to
shareholders under the Federal alternative minimum tax.     
   
The Diversified Assets Portfolio may also invest up to 5% of its net assets
from time to time in municipal instruments or other securities issued by state
and local governmental bodies when, as a result of prevailing economic,
regulatory or other circumstances, the yield of such securities, on a pre-tax
basis, is comparable to that of other permitted short-term taxable investments.
Dividends paid on such investments will be taxable to shareholders.     
   
ISSUER DIVERSIFICATION. In accordance with current SEC regulations, each
Portfolio intends to limit investments in the securities of any single issuer
(excluding cash, cash items, certain repurchase agreements, U.S. Government
securities or securities of other investment companies) to not more than 5% of
the value of its total assets at the time of purchase, except that (a) 25% of
the value of the total assets of each Portfolio may be invested in the
securities of any one issuer for a period of up to three Business Days; and (b)
securities subject to certain unconditional guarantees are subject to different
diversification requirements as described in the Additional Statement. In
addition, the Portfolios will limit their investments in securities that are
not First Tier Securities as prescribed by SEC regulations.     
   
DERIVATIVE INSTRUMENTS. Each Portfolio may also purchase certain "derivative"
instruments. "Derivative" instruments are instruments that derive value from
the performance of underlying assets, interest rates or indices, and include
(but are not limited to) various structured debt obligations (including certain
variable and floating rate instruments). Derivative instruments present, to
varying degrees, market risk that the performance of the underlying assets,
interest rates or indices will decline; credit risk that the dealer or other
counterparty to the transaction will fail to pay its obligations; volatility
risk that, if interest rates change adversely, the value of the derivative
instrument will decline more than the assets, rates or indices on which it is
based; liquidity risk that a Portfolio will be unable to sell a derivative
instrument when it wants because of lack of market depth or market disruption;
pricing risk that the value of a derivative instrument will not correlate
exactly to the value of the underlying assets, rates or indices on which it is
based; and operations risk that loss will occur as a result of inadequate
systems and controls, human error or otherwise. Some derivative instruments are
more complex than others, and for those instruments that have been developed
recently, information is lacking regarding their actual performance over
complete market cycles. Northern will evaluate the risks presented by the
derivative instruments purchased by the Portfolios, and will determine, in
connection with its day-to-day management of the Portfolios, how they will be
used in furtherance of the Portfolios' investment objectives. It is possible,
however, that Northern's evaluations will prove to be inaccurate or incomplete
and, even when accurate and complete, it is possible that the Portfolios will,
because of the risks discussed above, incur loss as a result of their
investments in derivative instruments.     
   
ILLIQUID OR RESTRICTED SECURITIES. A Portfolio will not invest more than 10% of
its net assets in securities which are illiquid, including repurchase
agreements and time deposits that do not provide for payment to the Trust
within seven days after notice and certificates of participation for which
there is no readily available secondary market and certain securities which are
subject to trading restrictions because they are not registered under the
Securities Act of 1933 (the "1933 Act").     
 
 
                                       13
<PAGE>
 
   
If otherwise consistent with their investment objectives and policies, the
Portfolios may purchase commercial paper issued pursuant to Section 4(2) of the
1933 Act and securities that are not registered under the 1933 Act but can be
sold to "qualified institutional buyers" in accordance with Rule 144A under the
1933 Act. These securities will not be considered illiquid so long as Northern
determines, under guidelines approved by the Trust's Board of Trustees, that an
adequate trading market exists. This practice could increase the level of
illiquidity during any period that qualified institutional buyers become
uninterested in purchasing these securities.     
 
MISCELLANEOUS. Although the Portfolios will generally not seek profits through
short-term trading, each Portfolio may dispose of any portfolio security prior
to its maturity if, on the basis of a revised credit evaluation of the issuer
or other considerations, Northern believes such disposition is advisable.
Subsequent to its purchase, a portfolio security may be assigned a lower rating
or cease to be rated. Such an event would not necessarily require the
disposition of the security, if the continued holding of the security is
determined to be in the best interest of the Portfolio and its shareholders.
 
In determining the creditworthiness of the issuers of portfolio securities that
may be purchased and held by the Portfolios, Northern gathers and reviews
historical financial data and, through the use of a proprietary software
computer program, analyzes and attempts to assess the fundamental strengths and
weaknesses of individual issuers, industries and market sectors. Exposure
limits are established by Northern for each security in conformance with the
objectives and policies stated in this Prospectus, and are thereafter adjusted
periodically in response to changes in relevant credit factors.
          
Pursuant to an SEC order, each Portfolio may engage in principal transactions
effected in the ordinary course of business with Goldman Sachs.     
 
INVESTMENT RESTRICTIONS
 
The Portfolios are subject to certain investment restrictions which, as
described in more detail in the Additional Statement, are fundamental policies
that cannot be changed without the approval of a majority of the outstanding
shares of a Portfolio. Each Portfolio will limit its investments so that less
than 25% of the Portfolio's total assets will be invested in the securities of
issuers in any one industry (with certain limited exceptions). Each Portfolio
may borrow money from banks for temporary or emergency purposes or to meet
redemption requests, provided that the Portfolio maintains asset coverage of at
least 300% for all such borrowings.

                               TRUST INFORMATION
 
BOARD OF TRUSTEES
 
The business and affairs of the Trust and each Portfolio are managed under the
direction of the Trust's Board of Trustees. The Additional Statement contains
the name of each Trustee and background information regarding the Trustees.
 
INVESTMENT ADVISER, TRANSFER AGENT AND CUSTODIAN
 
Northern, which has offices at 50 S. LaSalle Street, Chicago, Illinois 60675,
serves as investment adviser, transfer agent and custodian for each Portfolio.
As transfer agent, Northern performs various shareholder servicing functions,
and any shareholder inquiries should be directed to it.
 
Northern, a member of the Federal Reserve System, is an Illinois state-
chartered commercial bank and the principal subsidiary of Northern Trust
Corporation, a bank holding company. Northern was formed in 1889 with
capitalization of $1 million. As of December 31, 1997, Northern Trust
Corporation and its subsidiaries had approximately $25.3 billion in assets,
$16.4 billion in deposits and employed over 7,553 persons.
   
Northern and its affiliates administered in various capacities (including as
master trustee, investment manager or custodian) approximately $1 trillion of
assets as of December 31, 1997, including approximately $196.5 billion of
assets for which Northern and its affiliates had investment management
responsibility.     
 
Under its Advisory Agreement with the Trust, Northern, subject to the general
supervision of the Trust's Board of Trustees, is responsible for making
investment decisions for the Portfolios and placing purchase and sale orders
for portfolio securities. Northern is also responsible for monitoring and
preserving the records required to be maintained under the regulations of the
SEC (with certain exceptions unrelated to its activities for the Trust). As
compensation for its advisory services and its assumption of related expenses,
Northern is entitled to a fee, computed daily and payable monthly, at an annual
rate of .25% of the average daily net assets of each Portfolio.
 
For serving as investment adviser during the fiscal year ended November 30,
1997, Northern earned fees paid by the Government Portfolio, the Diversified
Assets Portfolio and the Tax-Exempt Portfolio at the rate of .25% (per annum)
of each Portfolio's average daily net assets. For serving as investment adviser
during the fiscal year ended November 30, 1997, Northern earned fees (after
waivers) paid by the Government Select Portfolio at the rate of .10% (per
annum) of its average daily net assets.
   
Northern also receives compensation as the Trust's custodian and transfer agent
under separate agreements. The fees payable by the Portfolios for these
services are described in this Prospectus under "Summary of Expenses" and in
the Additional Statement. Different transfer agency fees are payable with
respect to the Portfolios' different share classes.     
   
YEAR 2000     
   
Like every other business dependent upon computerized information processing,
Northern Trust Corporation ("Northern Trust") must deal with "Year 2000"
issues, which stem from using two digits to reflect the year in computer
programs and data. Computer programmers and other designers of equipment that
use microprocessors have long abbreviated dates by eliminating the first two
digits of the year under the     
 
                                       15
<PAGE>
 
   
assumption that those two digits will always be 19. As the Year 2000
approaches, many systems may be unable to accurately process certain date-based
information, which could cause a variety of operational problems for
businesses.     
   
Northern Trust's data processing software and hardware provide essential
support to virtually all of its business units, including the units that
provide services to the Trust, so successfully addressing Year 2000 issues is
of the highest importance. Failure to complete renovation of the critical
systems used by Northern on a timely basis could have a materially adverse
effect on its ability to provide such services--as could Year 2000 problems
experienced by others. Although the nature of the problem is such that there
can be no complete assurance it will be successfully resolved, Northern Trust
has indicated that a renovation and risk mitigation program is well under way
and that it has a dedicated Year 2000 Project Team whose members have
significant systems development and maintenance experience. Northern Trust's
Year 2000 project includes a comprehensive testing plan. Northern Trust has
advised the Trust that it expects to complete work on its critical systems by
December 31, 1998, so that testing with outside parties may be conducted during
1999.     
   
Northern Trust is also will have a program to monitor and assess the efforts of
other parties. However, it cannot control the success of those efforts.
Contingency plans are being established where appropriate to provide Northern
Trust with alternatives in case these entities experience significant Year 2000
difficulties which impact Northern Trust.     
 
ADMINISTRATOR AND DISTRIBUTOR
 
Goldman Sachs, 85 Broad Street, New York, New York 10004, acts as administrator
and distributor for the Portfolios. Subject to the limitations described below,
as compensation for its administrative services (which include supervision with
respect to the Trust's non-investment advisory operations) and the assumption
of related expenses, Goldman Sachs is entitled to a fee from each Portfolio,
computed daily and payable monthly, at an annual rate of .10% of the average
daily net assets of each Portfolio. No compensation is payable by the Trust to
Goldman Sachs for its distribution services.
   
In addition, Goldman Sachs has agreed that it will reimburse each Portfolio's
expenses (including the fees payable to Goldman Sachs as administrator, but
excluding the fees payable to Northern for its duties as investment adviser and
transfer agent, payments under the service plan for the Portfolios' Service and
Premier Share classes and extraordinary expenses such as interest, taxes and
indemnification expenses) which exceed on an annualized basis .10% of such
Portfolio's average daily net assets for any fiscal year. In addition, as of
the date of this Prospectus, Northern will continue to reduce its advisory fee
for the Government Select Portfolio. The result of these reimbursements and fee
reductions will be to increase the yields of the Portfolios during the periods
for which the reimbursements and reductions are made.     
 
SERVICE PLAN
   
Pursuant to a Service Plan ("Service Plan") adopted by the Board of Trustees of
the Trust with respect to the Service Shares, banks, trust companies and other
institutions and organizations including Northern and its affiliates
("Servicing Agents") may enter into agreements ("Servicing Agreements") under
which they will render (or arrange for the rendering of) administrative support
services for Service Share investors for the fees described below ("Service
Fees").     
 
                                       16
<PAGE>
 
   
Administrative support services to be provided by Servicing Agents, which are
described more fully in the Additional Statement, may include establishing and
maintaining individual accounts and records with respect to Service Shares
owned by their Customers (as defined below), processing purchase, redemption
and exchange orders for their Customers, placing net purchase and redemption
orders with Northern acting as the Trust's transfer agent and providing cash
management or sweep accounts and similar programs and services for their
Customers. For these administrative support services, the Service Plan provides
for the payment of fees to Servicing Agents at an annual rate of up to .25% of
the average daily net asset value of the Service Shares beneficially owned by
their Customers. In addition, the Service Plan provides for the payment of fees
to Northern, Goldman Sachs or other institutions at an annual rate of up to
 .08% of the average daily net asset value of Service Shares serviced by such
institutions for ongoing consulting services, technology and systems support
services relating to cash management or sweep account services. All fees
payable under the Service Plan are borne solely by Service Shares and not by
the Portfolios' other share classes.     
   
Conflict of interest restrictions may apply to the receipt of compensation by
the Trust to a Servicing Agent in connection with the investment of fiduciary
funds in Service Shares. Banks and other institutions regulated by the Office
of Comptroller of the Currency, Board of Governors of the Federal Reserve
System and state banking commissions, and investment advisers and other money
managers subject to the jurisdiction of the SEC, the Department of Labor or
state securities commissions, are urged to consult legal counsel before
entering into Servicing Agreements.     
 
EXPENSES
   
Except as set forth above and in the Additional Statement under "Additional
Trust Information," each Portfolio is responsible for the payment of its
expenses. Such expenses include without limitation, the fees and expenses
payable to Northern and Goldman Sachs, fees for the registration or
qualification of Portfolio shares under Federal or state securities laws,
expenses of the organization of the Portfolio, taxes, 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 Trust for violation of any law, legal,
tax and auditing fees and expenses, Service Fees, expenses of preparing and
printing prospectuses, statements of additional information, proxy materials,
reports and notices and the printing and distributing of the same to the
Trust's shareholders and regulatory authorities, compensation and expenses of
its Trustees, expenses of industry organizations such as the Investment Company
Institute, miscellaneous expenses and extraordinary expenses incurred by the
Trust.

                                   INVESTING
 
PURCHASE OF SERVICE SHARES
   
Service Shares are offered to Northern, its affiliates and other institutions
and organizations, including certain defined contribution plans having at least
$30 million in assets or annual contributions of at least $5 million (the
"Institutions"), acting on behalf of their customers, clients, employees,
participants and others (the "Customers"). Service Shares of the Portfolios are
sold on a continuous basis by the Trust's distributor, Goldman Sachs, to
Institutions that have agreed to render (or arrange for the rendering of)
administrative support services to Customers pursuant to a Servicing Agreement
and either maintain certain institutional accounts with Northern or its
affiliates or invest an aggregate of at least $5 million in one or more
Portfolios of the Trust. See "Trust Information--Servicing Plan" above. The
Trust has established procedures for purchasing Service Shares in order to
accommodate different types of Institutions.     
   
PURCHASE OF SERVICE SHARES THROUGH INSTITUTIONAL ACCOUNTS. Any Institution
maintaining an institutional account at Northern or an affiliate may make
purchases through such institutional account either by directing automatic
investment of cash balances in excess of certain agreed upon amounts or by
directing investments from time to time on a non-automatic basis. The nature of
an Institution's relationship with Northern or an affiliate will determine
whether the Institution maintains an institutional account as well as the
procedures available for purchases. Institutions should contact Northern or an
affiliate for further information in this regard. There is no minimum initial
investment for Institutions that maintain institutional accounts with Northern
or its affiliates.     
 
PURCHASE OF SERVICE SHARES DIRECTLY FROM THE TRUST. An Institution that
purchases Service Shares directly may do so by means of one of the following
procedures, provided it makes an aggregate minimum initial investment of $5
million in one or more Portfolios of the Trust:
     
  PURCHASE BY MAIL. An Institution desiring to purchase Service Shares of a
  Portfolio by mail should mail a check or Federal Reserve draft payable to
  the specific Portfolio together with a completed and signed new account
  application to The Benchmark Funds, c/o The Northern Trust Company,
  P.O. Box 75943, Chicago, Illinois 60675-5943. An application will be
  incomplete if it does not include a corporate resolution with the corporate
  seal and secretary's certification or other acceptable evidence of
  authority. If an Institution desires to purchase the Service Shares of more
  than one Portfolio, the Institution should send a separate check for each
  Portfolio. All checks must be payable in U.S. dollars and drawn on a bank
  located in the United States. A $20 charge will be imposed if a check does
  not clear. The proceeds of redemptions of shares purchased by check may be
  delayed up to 15 days to allow the Trust to determine that the check has
  cleared and been paid. Cash and third party checks are not acceptable for
  the purchase of Service Shares.     
 
  PURCHASE BY TELEPHONE. An Institution desiring to purchase Service Shares
  of a Portfolio by telephone should call Northern acting as the Trust's
  transfer agent ("Transfer Agent") at 1-800-637-1380. Please be prepared to
  identify the name of the Portfolio with respect to which Service Shares are
  to be purchased and the manner of payment. Please indicate whether a new
  account is being established or an additional payment is being made to an
  existing account. If an additional payment is being made to an existing
  account, please provide the Institution's name and Portfolio Account
  Number. Purchase orders are
 
                                       18
<PAGE>
 
  effected upon receipt by the Transfer Agent of Federal funds or other
  immediately available funds in accordance with the terms set forth below.
 
  PURCHASE BY WIRE OR ACH TRANSFER. An Institution desiring to purchase
  Service Shares of a Portfolio by wire or ACH Transfer should call the
  Transfer Agent at 1-800-637-1380 for instructions if it is not making an
  additional payment to an existing account. An Institution that wishes to
  add to an existing account should wire Federal funds or effect an ACH
  Transfer to:
 
                      The Northern Trust Company
                      Chicago, Illinois
                      ABA Routing No. 0710-00152
                      (Reference 10 Digit Portfolio Account Number)
                         
                      (Reference Shareholder's Name)     
 
  For other information concerning requirements for the purchase of Service
  Shares, call the Transfer Agent at 1-800-637-1380.
   
EFFECTIVE TIME OF PURCHASES. Except as provided below under "Miscellaneous," a
purchase order for Service Shares placed with the Transfer Agent by 1:00 p.m.,
Chicago time, on a Business Day (as defined under "Miscellaneous") will be
effected on that Business Day at the net asset value next determined on that
day with respect to a Portfolio, provided that the Transfer Agent receives the
purchase price in Federal funds or other immediately available funds prior to
1:00 p.m., Chicago time, on the same Business Day such order is received.
Orders received after 1:00 p.m. on a Business Day will be effected at the net
asset value next determined on the following Business Day, provided that
payment is received as provided herein. Purchase orders received on a non-
Business Day will not be executed until the following Business Day in
accordance with the foregoing procedures. An order generated pursuant to an
automatic investment direction of an Institution that has an institutional
account with Northern or its affiliates will normally be placed either on the
Business Day that funds are available in such account or on the first Business
Day thereafter, depending upon the terms of the Institution's automatic
investment arrangements. Shares of a Portfolio are entitled to the dividends
declared by the Portfolio beginning on the Business Day the purchase order is
executed.     
 
MISCELLANEOUS PURCHASE INFORMATION. Shares are purchased without a sales charge
imposed by the Trust. The minimum initial investment is $5 million for
Institutions that invest directly in one or more investment portfolios of the
Trust. The Trust reserves the right to waive this minimum and to determine the
manner in which the minimum investment is satisfied. There is no minimum for
subsequent investments.
 
Institutions intending to place a purchase order of $5 million or more directly
with the Trust through the Transfer Agent are requested to give advance notice
to the Transfer Agent no later than 11:00 a.m. Chicago Time on a Business Day
in order to assist in the processing of the order.
 
See "Miscellaneous" below for information on when the Trust may advance the
time by which purchase requests must be received.
 
Institutions may impose minimum investment and other requirements on Customers
purchasing shares through them. Depending on the terms governing the particular
account, Institutions may impose account charges such as asset allocation fees,
account maintenance fees, compensating balance requirements or other
 
                                       19
<PAGE>
 
   
charges based upon account transactions, assets or income, which will have the
effect of reducing the net return on an investment in a Portfolio. In addition,
Institutions will enter into Servicing Agreements with the Trust whereby they
will perform (or manage to have performed) various administrative support
services for Customers who are the beneficial owners of Service Shares. These
services may include providing sweep accounts or similar programs to their
Customers. See "Trust Information--Service Plan." The exercise of voting rights
and the delivery to Customers of shareholder communications from the Trust will
be governed by the Customers' account agreements with the Institutions.
Customers should read this Prospectus in connection with any relevant agreement
describing the services provided by an Institution and any related requirements
and charges, or contact the Institution at which the Customer maintains its
account for further information.     
 
Institutions that purchase shares on behalf of Customers are responsible for
transmitting purchase orders to the Transfer Agent and delivering required
Federal funds on a timely basis. An Institution will be responsible for all
losses and expenses of a Portfolio as a result of a check that does not clear,
an ACH transfer that is rejected, or any other failure to make payment in the
time and manner described above, and Northern may redeem shares from an account
it maintains to protect the Portfolio and Northern against loss. The Trust
reserves the right to reject any purchase order. In those cases in which an
Institution pays for shares by check, Federal funds will generally become
available two Business Days after a purchase order is received. Federal
regulations require that the Transfer Agent be furnished with a taxpayer
identification number upon opening or reopening an account. Purchase orders
without such a number or an indication that a number has been applied for will
not be accepted. If a number has been applied for, the number must be provided
and certified within sixty days of the date of the order.
 
Payment for shares of a Portfolio may, in the discretion of Northern, be made
in the form of securities that are permissible investments for the Portfolio.
For further information about the terms of such purchases, see the Additional
Statement.
 
In the interests of economy and convenience, certificates representing shares
of the Portfolios are not issued.
 
Institutions investing in the Portfolios on behalf of their Customers should
note that state securities laws regarding the registration of dealers may
differ from the interpretations of Federal law and such institutions may be
required to register as dealers pursuant to state law.
   
Northern may, at its own expense, provide compensation to certain dealers and
other financial intermediaries who provide services to their Customers who
invest in the Trust or whose Customers purchase significant amounts of shares
of a Portfolio. The amount of such compensation may be made on a one-time
and/or periodic basis, and may represent all or a portion of the annual fees
that are earned by Northern as investment adviser to such Portfolio (after
adjustments) and are attributable to shares held by such Customers. Such
compensation will not represent an additional expense to the Trust or its
shareholders, since it will be paid from assets of Northern or its affiliates.
    
REDEMPTION OF SERVICE SHARES
   
Institutions may redeem shares of a Portfolio through procedures established by
Northern and its affiliates in connection with the requirements of their
institutional accounts or through procedures set forth herein with respect to
Institutions that invest directly.     
 
                                       20
<PAGE>
 
   
REDEMPTION OF SHARES THROUGH INSTITUTIONAL ACCOUNTS. Institutions may redeem
shares in their institutional accounts at Northern or its affiliates. For
Institutions that participate in an automatic investment service described
above under "Purchase of Service Shares," Northern or its affiliates will
calculate on each Business Day the number of shares that need to be redeemed in
order to bring the Institution's account up to any agreed upon minimum amount.
Redemption requests on behalf of an Institution will normally be placed either
on the Business Day the redemption amount is calculated or on the first
Business Day thereafter, depending upon the terms of the Institution's
automatic investment arrangements. In the latter case, however, Northern or its
affiliates normally will provide funds by provisionally crediting the
institutional account of the Institution on the Business Day on which the
calculation is made. The nature of an Institution's relationship with Northern
or an affiliate will determine whether the Institution maintains an
"institutional account" as well as the procedures available for redemptions.
Institutions should contact Northern or an affiliate for further information in
this regard.     
 
REDEMPTION OF SHARES DIRECTLY. Institutions that purchase shares directly from
the Trust through the Transfer Agent may redeem all or part of their Portfolio
shares in accordance with the procedures set forth below.
 
  REDEMPTION BY MAIL. An Institution may redeem shares by sending a written
  request to The Benchmark Funds, c/o The Northern Trust Company, P.O. Box
  75943, Chicago, Illinois 60675-5943. Redemption requests must be signed by
  a duly authorized person, and must state the number of shares or the dollar
  amount to be redeemed and identify the Portfolio Account Number. See "Other
  Requirements."
 
  REDEMPTION BY TELEPHONE. An Institution may redeem shares by placing a
  redemption order by telephone by calling the Transfer Agent at 1-800-637-
  1380. During periods of unusual economic or market changes, telephone
  redemptions may be difficult to implement. In such event, shareholders
  should follow procedures outlined above under "Redemption by Mail."
 
  REDEMPTION BY WIRE. If an Institution has given authorization for expedited
  wire redemption, shares can be redeemed and the proceeds sent by Federal
  wire transfer to a single previously designated bank account. The minimum
  amount which may be redeemed by this method is $10,000. The Trust reserves
  the right to change or waive this minimum or to terminate the wire
  redemption privilege. See "Other Requirements."
 
  TELEPHONE PRIVILEGE. An Institution that has notified the Transfer Agent in
  writing of the Institution's election to redeem or exchange shares by
  placing an order by telephone may do so by calling the Transfer Agent at
  1-800-637-1380. Neither the Trust nor its Transfer Agent will be
  responsible for the authenticity of instructions received by telephone that
  are reasonably believed to be genuine. To the extent that the Trust fails
  to use reasonable procedures to verify the genuineness of telephone
  instructions, it or its service providers may be liable for such
  instructions that prove to be fraudulent or unauthorized. In all other
  cases, the shareholder will bear the risk of loss for fraudulent telephone
  transactions. However, the Transfer Agent has adopted procedures in an
  effort to establish reasonable safeguards against fraudulent telephone
  transactions. The proceeds of redemption orders received by telephone will
  be sent by check, by wire or by transfer pursuant to proper instruments.
  All checks will be made payable to the shareholder of record and mailed
  only to the shareholder's address of record. See "Other Requirements."
  Additionally, the Transfer Agent utilizes recorded lines for telephone
  transactions and retains such tape
 
                                       21
<PAGE>
 
  recordings for six months, and will request a form of identification if
  such identification has been furnished to the Transfer Agent or the Trust.
     
  OTHER REQUIREMENTS. A change of wiring instructions and a change of the
  address of record may be effected only by a written request to the Transfer
  Agent accompanied by (i) a corporate resolution which evidences authority
  to sign on behalf of the Institution (including the corporate seal and
  secretary's certification), (ii) a signature guarantee by a financial
  institution that is a participant in the Stock Transfer Agency Medallion
  Program ("STAMP") in accordance with rules promulgated by the SEC (a
  signature notarized by a notary public is not acceptable) or (iii) such
  other means or evidence of authority as may be acceptable to the Transfer
  Agent. A redemption request by mail will not be effective unless signed by
  a person authorized by the corporate resolution or other acceptable
  evidence of authority on file with the Transfer Agent.     
   
EXCHANGE PRIVILEGE. Institutions and, to the extent permitted by their account
agreements, Customers, may, after appropriate prior authorization, exchange
Service Shares of a Portfolio having a value of at least $1,000 for Service
Shares of other Portfolios as to which the Institution or Customer maintains an
existing account with an identical title.     
   
Exchanges will be effected by a redemption of shares of the Portfolio held and
the purchase of shares of the portfolio acquired. Customers of Institutions
should contact their Institutions for further information regarding the Trust's
exchange privilege and Institutions should contact the Transfer Agent as
appropriate. Customers and Institutions exercising the exchange privilege
should read the relevant prospectus prior to making an exchange. The Trust
reserves the right to modify or terminate the exchange privilege at any time
upon 60 days' written notice to shareholders of record and to reject any
exchange request. Exchanges are only available in states where an exchange can
legally be made.     
   
EFFECTIVE TIME OF REDEMPTIONS AND EXCHANGES. Redemption orders of Portfolio
shares are effected at the net asset value per share next determined after
receipt in good order by the Transfer Agent. Good order means that the request
includes the following: the account number and Portfolio name; the amount of
the transaction (as specified in dollars or shares); and the signature of a
duly authorized person (except for telephone and wire redemptions). See
"Investing--Redemption of Service Shares--Other Requirements." Exchange orders
are effected at the net asset value per share next determined after receipt in
good order by the Transfer Agent. Payment for redeemed shares for which a
redemption order is received by Northern with respect to an institutional
account it maintains or the Transfer Agent as of 1:00 p.m., Chicago time, on a
Business Day normally will be made in Federal funds or other immediately
available funds wired or sent by check to the redeeming shareholder or, if
selected, the shareholder's institutional account with Northern on that
Business Day. Redemption orders received after 1:00 p.m. will be effected the
next Business Day. Proceeds for redemption orders received on a non-Business
Day will normally be sent on the next Business Day after receipt in good order.
    
MISCELLANEOUS REDEMPTION AND EXCHANGE INFORMATION. All redemption proceeds will
be sent by check unless Northern or the Transfer Agent is directed otherwise.
The ACH system may be utilized for payment of redemption proceeds. Redemption
of shares may not be effected if a shareholder has failed to submit a completed
and properly executed (with corporate resolution or other acceptable evidence
of authority) new account application. Institutions intending to place exchange
and redemption orders for same day proceeds
 
                                       22
<PAGE>
 
of $5 million or more directly with the Trust through the Transfer Agent are
requested to give advance notice to the Transfer Agent no later than 11:00 a.m.
Chicago Time on a Business Day. The proceeds of redemptions of shares purchased
by check may be delayed up to 15 days to allow the Trust to determine that the
check has cleared and been paid. The Trust reserves the right to defer
crediting, sending or wiring redemption proceeds for up to seven days after
receiving a redemption order if, in its judgment, an earlier payment could
adversely affect a Portfolio.
 
See "Miscellaneous" below for information on when the Trust may advance the
time by which redemption and exchange requests must be received.
 
The Trust may require any information reasonably necessary to ensure that a
redemption has been duly authorized. Dividends on shares are earned through and
including the day prior to the day on which they are redeemed.
 
It is the responsibility of Institutions acting on behalf of Customers to
transmit redemption orders to the Transfer Agent and to credit Customers'
accounts with the redemption proceeds on a timely basis. If a Customer has
agreed with a particular Institution to maintain a minimum balance in his
account at such Institution and the balance in such account falls below that
minimum, such Customer may be obliged to redeem all or part of his shares to
the extent necessary to maintain the required minimum balance.
 
DISTRIBUTIONS
 
Shareholders of each Portfolio are entitled to dividends and distributions
arising from the net income and capital gains, if any, earned on investments
held by the particular Portfolio. Dividends from each Portfolio's net income
are declared daily as a dividend to shareholders of record at the close of
business on the days the dividends are declared (or 3:00 p.m., Chicago time, on
non-Business Days).
 
Net income of the Service Shares of each Portfolio includes interest accrued on
the assets of such Portfolio and allocated to its Service Shares less the
estimated expenses charged to the Service Shares of such Portfolio. Net
realized short-term capital gains of each Portfolio will be distributed at
least annually. The Portfolios do not expect to realize net long-term capital
gains.
   
Dividends declared during a calendar month will be paid as soon as practicable
following the end of the month, except that such dividends will be paid
promptly upon a total redemption of shares in any account not subject to a
standing order for the purchase of shares. All distributions are paid by each
Portfolio in cash or are automatically reinvested (without any sales charge) in
additional Service Shares of the same Portfolio. Arrangements may be made for
the crediting of such distributions to a shareholder's account with Northern,
its affiliates or its correspondent banks.     
 
TAXES
 
Management of the Trust intends that each Portfolio will qualify as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended (the "Code") as long as such qualification is in the best interest of
the Portfolio's shareholders. Such qualification generally relieves each
Portfolio of liability for Federal income taxes to the extent its earnings are
distributed in accordance with the Code, but shareholders,
 
                                       23
<PAGE>
 
unless otherwise exempt, will pay income taxes on amounts so distributed
(except distributions that constitute "exempt-interest dividends" or that are
treated as a return of capital). Dividends paid from net short-term capital
gains are treated as ordinary income dividends. None of the Portfolios'
distributions will be eligible for the corporate dividends received deduction.
 
The Tax-Exempt Portfolio intends to pay substantially all of its dividends as
"exempt-interest dividends." Investors in the Portfolio should note, however,
that taxpayers are required to report the receipt of tax-exempt interest and
"exempt-interest dividends" on their Federal income tax returns and that in two
circumstances such amounts, while exempt from regular Federal income tax, are
taxable to persons subject to alternative minimum taxes. First, tax-exempt
interest and "exempt-interest dividends" derived from certain private activity
bonds issued after August 7, 1986 generally will constitute an item of tax
preference for corporate and noncorporate taxpayers in determining alternative
minimum tax liability. Second, all tax-exempt interest and "exempt-interest
dividends" must be taken into account by corporate taxpayers in determining
certain adjustments for alternative minimum tax purposes. Shareholders who are
recipients of Social Security Act or Railroad Retirement Act benefits should
note that tax-exempt interest and "exempt-interest dividends" will be taken
into account in determining the taxability of their benefit payments. To the
extent, if any, that dividends paid by the Tax-Exempt Portfolio to its
shareholders are derived from taxable interest or from capital gains, such
dividends will be subject to Federal income tax, whether received in cash or
reinvested in additional shares.
 
The Tax-Exempt Portfolio will determine annually the percentages of its net
investment income which are exempt from the regular Federal income tax, which
constitute an item of tax preference for purposes of the Federal alternative
minimum tax, and which are fully taxable and will apply such percentages
uniformly to all distributions declared from net investment income during that
year. These percentages may differ significantly from the actual percentages
for any particular day.
 
The Trust will send written notices to shareholders annually regarding the tax
status of distributions made by each Portfolio. Dividends declared in October,
November or December of any year payable to shareholders of record on a
specified date in those months will be deemed for Federal tax purposes to have
been paid by a Portfolio and to have been received by the shareholders on
December 31 of that year, if the dividends are actually paid during the
following January.
 
The foregoing discussion is only a brief summary of some of the important tax
considerations generally affecting the Portfolios and their shareholders and is
not intended as a substitute for careful tax planning. Accordingly, investors
should consult their tax advisers with specific reference to their own Federal,
state and local tax situation. In particular, although the Government Select
Portfolio intends to invest primarily in U.S. Government securities the
interest on which is generally exempt from state income taxation, an investor
should consult his or her own tax adviser to determine whether distributions
from the Portfolio are exempt from state income taxation in the investor's own
situation. Similarly, dividends paid by the Portfolios may be taxable to
investors under state or local law as dividend income even though all or a
portion of such dividends may be derived from interest on obligations which, if
realized directly, would be exempt from such income taxes. Future legislative
or administrative changes or court decisions may materially affect the tax
consequences of investing in one or more of the Portfolios.
 
                                       24
<PAGE>
 
                                NET ASSET VALUE
   
The net asset value per share of each Portfolio for purposes of purchases and
redemptions is calculated by Northern as of 3:00 p.m., Chicago time,
immediately after the declaration of net income earned by shareholders of
record, on each Business Day (as defined below under "Miscellaneous"), except
for days during which no shares are tendered to the Portfolio for redemption
and no orders to purchase or sell shares are received by the Portfolio and
except for days on which there is an insufficient degree of trading in the
Portfolio's securities for changes in the value of such securities to
materially affect the net asset value per share. The time at which the net
asset value per share of a Portfolio is calculated may be advanced on days on
which Northern or the securities markets close early. See "Miscellaneous"
below. Net asset value per Service Share of each Portfolio is calculated by
adding the value of all securities and other assets belonging to the Portfolio
that are allocated to the Service Shares, subtracting the liabilities charged
to the Service Shares and dividing by the number of Service Shares of the
Portfolio outstanding.     
 
In seeking to maintain a net asset value of $1.00 per share with respect to
each Portfolio for purposes of purchases and redemptions, the Trust values the
portfolio securities held by a Portfolio pursuant to the amortized cost
method. Under this method, 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 of maturity. See "Amortized Cost
Valuation" in the Additional Statement. There can be no assurance that a
Portfolio will be able at all times to maintain a net asset value per share of
$1.00.
 
                            PERFORMANCE INFORMATION
 
From time to time the Portfolios may advertise the "yields" and "effective
yields", and the Government Select Portfolio and Tax-Exempt Portfolio may
advertise the "tax-equivalent yields", of Service Shares. These yield figures
will fluctuate, are based on historical earnings and are not intended to
indicate future performance. "Yield" refers to the net investment income
generated by an investment in the Portfolio over a seven-day period identified
in the advertisement. This net investment income is then "annualized." That
is, the amount of net investment income generated by the investment during
that week is assumed to be generated each week over a 52-week period and is
shown as a percentage of the investment. "Effective yield" is calculated
similarly but, when annualized, the net investment income earned by an
investment in the Portfolio is assumed to be reinvested. The "effective yield"
will be slightly higher than the "yield" because of the compounding effect of
this assumed reinvestment. The "tax-equivalent yield" demonstrates the level
of taxable yield necessary to produce an after-tax yield equivalent to a
Portfolio's tax-free yield. It is calculated by taking that portion of the
seven-day "yield" which is tax-exempt and adjusting it to reflect the tax
savings associated with a stated tax rate. The "tax-equivalent yield" will
always be higher than the Portfolio's yield.
 
The Portfolios' yields may not provide a basis for comparison with bank
deposits and other investments which provide a fixed yield for a stated period
of time. Yield will be affected by portfolio quality, composition, maturity,
market conditions and the level of the Portfolio's operating expenses.
 
Each Portfolio may also quote from time to time the total return on its
Service Shares in accordance with SEC regulations.
 
                                      25
<PAGE>
 
                                  ORGANIZATION
   
Each Portfolio is a series of The Benchmark Funds, which was formed as a
Delaware business trust on July 1, 1997 under an Agreement and Declaration of
Trust. The Portfolios were formerly series of The Benchmark Funds, a
Massachusetts business trust, and were reorganized into the Trust on March 31,
1998. As of the date of this Prospectus, the Trust has created eighteen
separate series of shares of beneficial interest representing interests in
eighteen investment portfolios, four of which are described in this Prospectus;
the other series of shares are described in a separate prospectus. The business
and affairs of the Trust are managed by or under the direction of its Board of
Trustees. The Declaration of Trust of the Trust authorizes the Board of
Trustees to classify or reclassify any unissued shares into additional series
or classes within a series. Pursuant to such authority, the Board of Trustees
has classified three classes of shares in each Portfolio: the Shares, Service
Shares and Premier Shares. This Prospectus relates only to Service Shares of
the Portfolios described herein.     
   
Each share of a Portfolio is without par value, represents an equal
proportionate interest in that Portfolio with each other share of its class in
that Portfolio and is entitled to such dividends and distributions earned on
such Portfolio's assets as are declared in the discretion of the Board of
Trustees. Shares of each class bear their pro rata portion of all operating
expenses paid by a Portfolio, except transfer agency fees and amounts payable
under the Service Plan relating to Service Shares and Premier Shares. Because
of these class-specific expenses, the performance of a Portfolio's Service
Shares is expected to be higher than the performance of the Portfolio's Premier
Shares but lower than that of the Portfolio's other class of shares. Any person
entitled to receive compensation for selling or servicing shares of a Portfolio
may receive different compensation with respect to one particular class of
shares over another in the same Portfolio. For further information regarding
the Trust's other share classes, contact Goldman Sachs at 1-800-621-2550.     
   
The Trust's shareholders are entitled at the discretion of the Board of
Trustees to vote either on the basis of the number of shares held or the
aggregate net asset value represented by such shares. Each series entitled to
vote on a matter will vote thereon in the aggregate and not by series, except
as otherwise required by law or when the matter to be voted on affects only the
interests of shareholders of a particular series. The Additional Statement
gives examples of situations in which the law requires voting by series. Voting
rights are not cumulative and, accordingly, the holders of more than 50% of the
aggregate voting power of the Trust may elect all of the Trustees irrespective
of the vote of the other shareholders. In addition, holders of all shares
(regardless of class) representing interests in the same Portfolio have equal
voting rights except that only shares of a particular class within the
Portfolio will be entitled to vote on matters submitted to a vote of
shareholders (if any) relating to class-specific expenses that are payable by
that class of shares.     
   
As of February 28, 1998, Northern possessed sole or shared voting or investment
power for its customer accounts with respect to more than 50% of the
outstanding shares of the Trust.     
   
The Trust does not presently intend to hold annual meetings of shareholders
except as required by the 1940 Act or other applicable law. The Trustees will
promptly call a meeting of shareholders to vote upon the removal of any Trustee
when so requested in writing by the record holders of 10% or more of the
outstanding shares. To the extent required by law, the Trust will assist in
shareholder communications in connection with such a meeting.

As used in this Prospectus, the term "Business Day" refers to each day when
Northern and the New York Stock Exchange are open, which is Monday through
Friday, except for holidays observed by Northern and/or the Exchange other than
Good Friday. For 1998, the holidays of Northern and/or the Exchange are: New
Year's Day, Dr. Martin Luther King, Jr. Day, Presidents' Day, Memorial Day,
Independence Day, Labor Day, Columbus Day, Veteran's Day, Thanksgiving and
Christmas Day. On those days when Northern or the Exchange closes early as a
result of unusual weather or other circumstances, the Portfolios reserve the
right to advance the time on that day by which purchase, redemption and
exchange requests must be received. In addition, on any Business Day when The
Bond Market Association recommends that the securities markets close or close
early, the Portfolios reserve the right to cease or to advance the deadline for
accepting purchase, redemption and exchange orders for same Business Day
credit. Purchase, redemption and exchange requests received after the advanced
closing time will be effected on the next Business Day. Each Portfolio
reserves, however, the right to reject any purchase order and also to defer
crediting, sending or wiring redemption proceeds for up to seven days after
receiving a redemption order if, in its judgment, an earlier payment would
adversely affect such Portfolio. See "Investing--Purchase of Service Shares"
and "Investing--Redemption of Service Shares" above for more information.

DESCRIPTION OF TRUST
 
The Trust is an open-end, management investment company registered under the
Investment Company Act of 1940 (the "1940 Act"). Each Portfolio consists of a
separate pool of assets with separate investment policies, as described below
under "Investment Information." All of the Portfolios are classified as
diversified companies. Northern serves as investment adviser, transfer agent
and custodian. Goldman Sachs serves as distributor and administrator.
 
Shares of the Portfolios are offered exclusively to institutional investors.
See "Investing--Purchase of Premier Shares" and "Investing--Redemption of
Premier Shares" for information on how to place purchase and redemption orders.
 
Each Portfolio seeks to maintain a net asset value of $1.00 per share. The
assets of each Portfolio will be invested in dollar-denominated debt securities
with remaining maturities of thirteen months or less as defined by the
Securities and Exchange Commission (the "SEC"), and each Portfolio's dollar-
weighted average portfolio maturity will not exceed 90 days. All securities
acquired by the Portfolios will be determined by Northern, under guidelines
established by the Trust's Board of Trustees, to present minimal credit risks,
and will be "Eligible Securities" as defined by the SEC. There can be no
assurance that the Portfolios will be able to achieve a stable net asset value
on a continuous basis, or that they will achieve their investment objectives.
 
Investors should note that one or more of the Portfolios may purchase variable
and floating rate instruments, enter into repurchase agreements, reverse
repurchase agreements and securities loans, acquire U.S. dollar-denominated
instruments of foreign issuers and make limited investments in illiquid
securities and securities issued by other investment companies. These
investment practices involve investment risks of varying degrees. None of the
Portfolios will invest in instruments denominated in a foreign currency.
 
SUMMARY OF EXPENSES
 
The following table sets forth the estimated annualized operating expenses for
Premier Shares of the Portfolios for the current fiscal year. Hypothetical
examples based on the table are also shown.

EXAMPLE OF EXPENSES. Based on the foregoing table, you would pay the following
expenses on a hypothetical $1,000 investment in Premier Shares, assuming a 5%
annual return and redemption at the end of each time period:

(1) "Other Expenses" include the payment of a fee to Northern, Goldman Sachs or
    other institutions under the service plan equal to .08% of the average
    daily net asset value of the Premier Shares. See "Trust Information--
    Service Plan" for additional information.     
   
The information with respect to Premier Shares is estimated and reflects the
expenses each Portfolio expects to incur with respect to such Shares during the
current fiscal year. The expense information included in the table and the
hypothetical example above relate only to Premier Shares (the class offered by
this Prospectus) and should not be considered as representative of past or
future performance. During the Trust's last fiscal year, Northern voluntarily
reduced its advisory fee for the Government Select Portfolio (payable at the
annual rate of .25% of the Portfolio's average daily net assets) to .10% per
annum. For the fiscal period December 1, 1996 through April 30, 1997, Goldman
Sachs charged an administration fee with respect to each Portfolio during such
period at the annual rate of .25% of the first $100 million, .15% of the next
$200 million, .075% of the next $450 million and .05% of any excess over $750
million of the Portfolio's average daily net assets. For the period May 1, 1997
through November 30, 1997, Goldman Sachs was entitled to an administration fee
equal to .10% of the average daily net assets of each Portfolio. In addition,
during the fiscal year, Goldman Sachs reimbursed each Portfolio's expenses
(including the fees payable to Goldman Sachs as administrator, but excluding
the fees payable to Northern for its duties as adviser and certain
extraordinary expenses) which exceeded on an annualized basis .10% of the
Portfolio's average daily net assets for such fiscal year. On April 1, 1998,
upon the offering of the Portfolios' Premier Shares and Service Shares, Goldman
Sachs will reimburse each Portfolio's expenses (including fees payable to
Goldman Sachs as administrator, but excluding the fees payable to Northern for
its duties as adviser and transfer agent, payments under the service plan for
    
                                       4
<PAGE>
 
   
the Portfolios' Premier Shares and Service Shares and certain extraordinary
expenses) which exceed on an annualized basis .10% of the Portfolio's average
daily net assets. Without the undertakings of Northern and Goldman Sachs,
"Other Expenses" of the Government Select, Government, Diversified Assets and
Tax-Exempt Portfolios would be .22%, .20%, .19% and .22%, respectively; and
"Total Operating Expenses" of the Government Select, Government, Diversified
Assets and Tax-Exempt Portfolios would be .99%, .97%, .96% and .99%,
respectively. For a more complete description of the Portfolios' expenses, see
"Trust Information" in this Prospectus.     
 
                             ---------------------
 
THE PURPOSE OF THE FOREGOING TABLE IS TO ASSIST YOU IN UNDERSTANDING THE
VARIOUS SHAREHOLDER TRANSACTION AND OPERATING EXPENSES OF EACH PORTFOLIO THAT
SHAREHOLDERS BEAR DIRECTLY OR INDIRECTLY. IT DOES NOT, HOWEVER, REFLECT ANY
CHARGES WHICH MAY BE IMPOSED BY NORTHERN, ITS AFFILIATES AND CORRESPONDENT
BANKS AND OTHER INSTITUTIONS ON THEIR CUSTOMERS AS DESCRIBED UNDER "INVESTING--
PURCHASE OF PREMIER SHARES." THE EXAMPLE SHOWN ABOVE SHOULD NOT BE CONSIDERED A
REPRESENTATION OF PAST OR FUTURE EXPENSES OR RATE OF RETURN. ACTUAL EXPENSES
AND RATE OF RETURN MAY BE MORE OR LESS THAN THOSE SHOWN.

                             INVESTMENT INFORMATION
 
The investment objective of each Portfolio, other than the Tax-Exempt
Portfolio, is to seek to maximize current income to the extent consistent with
the preservation of capital and maintenance of liquidity by investing
exclusively in high quality money market instruments. The Tax-Exempt Portfolio
seeks to provide its 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 investment objective of a Portfolio may not be changed without
the vote of the majority of the outstanding shares of the particular Portfolio
(as defined below under "Organization"). Except as expressly noted below,
however, a Portfolio's investment policies may be changed without a vote of
shareholders.
   
All securities acquired by the Portfolios will be determined by Northern, under
guidelines established by the Board of Trustees, to present minimal credit
risks and will be "Eligible Securities" as defined by the SEC. Eligible
Securities include, generally, (i) securities that either (a) have short-term
debt ratings at the time of purchase in the two highest rating categories by at
least two unaffiliated nationally recognized statistical rating organizations
("NRSROs") (or one NRSRO if the security is rated by only one NRSRO), or (b)
are issued or guaranteed by a person with such ratings, and (ii) securities
that are unrated (including securities of issuers that have long-term but not
short-term ratings) but are determined to be of comparable quality. Securities
that are in the highest short-term rating category as described above (and
unrated securities determined to be of comparable quality) are designated
"First Tier Securities." Under normal circumstances, the Government Select,
Government and Diversified Assets Portfolios intend to limit purchases of
securities to First Tier Securities. The Additional Statement includes a
description of applicable NRSRO ratings.     
 
Each Portfolio is managed so that the average maturity of all instruments in
the Portfolio (on a dollar-weighted basis) will not exceed 90 days. In no event
will the Portfolios purchase any securities which mature more than 13 months
from the date of purchase (except for certain variable and floating rate
instruments and securities collateralizing repurchase agreements). Securities
in which the Portfolios invest may not earn as high a level of income as long-
term or lower quality securities, which generally have greater market risk and
more fluctuation in market value.
 
GOVERNMENT SELECT PORTFOLIO
   
The Government Select Portfolio seeks to achieve its investment objective by
investing exclusively in securities issued or guaranteed as to principal and
interest by the U.S. Government, its agencies or instrumentalities. In making
investments, Northern will seek to acquire, under normal market conditions,
only those U.S. Government securities the interest on which is generally exempt
from state income taxation. Securities generally eligible for this exemption
include those issued by the U.S. Treasury and certain U.S. Government agencies
and instrumentalities, including the Federal Home Loan Bank and the Federal
Farm Credit Banks Funding Corp. The Portfolio intends to limit investments to
exempt U.S. Government securities. However, under extraordinary circumstances,
such as when appropriate exempt securities are unavailable, the Portfolio may
make investments in non-exempt U.S. Government securities and cash equivalents,
and may hold uninvested cash. See "Investing--Taxes" below for certain tax
considerations.     
 
                                       6
<PAGE>
 
GOVERNMENT PORTFOLIO
 
The Government Portfolio seeks to achieve its investment objective by investing
exclusively in:
     
  (A) Marketable securities issued or guaranteed as to principal and interest
  by the U.S. Government or by any of its agencies or instrumentalities and
  custodial receipts with respect thereto; and     
 
  (B) Repurchase agreements relating to the above instruments.
 
DIVERSIFIED ASSETS PORTFOLIO
 
In pursuing its investment objective, the Diversified Assets Portfolio may
invest in a broad range of government, bank and commercial obligations that are
available in the money markets. In particular, the Portfolio may invest in:
 
  (A) U.S. dollar-denominated obligations of U.S. banks with total assets in
  excess of $1 billion (including obligations of foreign branches of such
  banks);
 
  (B) U.S. dollar-denominated obligations of foreign commercial banks where
  such banks have total assets in excess of $5 billion;
 
  (C) High quality commercial paper and other obligations issued or
  guaranteed by U.S. and foreign corporations and other issuers rated (at the
  time of purchase) A-2 or higher by Standard & Poor's Ratings Group ("S&P"),
  Prime-2 or higher by Moody's Investors Service, Inc. ("Moody's"), Duff 2 or
  higher by Duff & Phelps Credit Rating Co. ("D&P"), F-2 or higher by Fitch
  IBCA, Inc. ("Fitch") or TBW-2 or higher by Thomson BankWatch, Inc. ("TBW");
 
  (D) Rated and unrated corporate bonds, notes, paper and other instruments
  that are of comparable quality to the commercial paper permitted to be
  purchased by the Portfolio;
 
  (E) Asset-backed securities (including interests in pools of assets such as
  mortgages, installment purchase obligations and credit card receivables);
 
  (F) Securities issued or guaranteed as to principal and interest by the
  U.S. Government or by its agencies or instrumentalities and custodial
  receipts with respect thereto;
     
  (G) U.S. dollar-denominated securities issued or guaranteed by one or more
  foreign governments or political subdivisions, agencies or
  instrumentalities thereof;     
 
  (H) Repurchase agreements relating to the above instruments; and
 
  (I) Securities issued or guaranteed by state or local governmental bodies.
 
TAX-EXEMPT PORTFOLIO
 
The Tax-Exempt Portfolio invests primarily in high quality short-term
instruments, the interest on which is, in the opinion of bond counsel for the
issuers, exempt from regular Federal income tax ("Municipal Instruments"). Such
opinions may contain various assumptions, qualifications or exceptions that are
reasonably acceptable to Northern. In particular, the Portfolio may invest in:
 
                                       7
<PAGE>
 
  (A) Fixed and variable rate notes and similar debt instruments rated MIG-2,
  VMIG-2 or Prime-2 or higher by Moody's, SP-2 or A-2 or higher by S&P, AA or
  higher by D&P or F-2 or higher by Fitch;
 
  (B) Tax-exempt commercial paper and similar debt instruments rated Prime-2
  or higher by Moody's, A-2 or higher by S&P, Duff 2 or higher by D&P or F-2
  or higher by Fitch;
 
  (C) Rated and unrated municipal bonds, notes, paper or other instruments
  that are of comparable quality to the tax-exempt commercial paper permitted
  to be purchased by the Portfolio; and
 
  (D) Municipal bonds and notes which are guaranteed as to principal and
  interest by the U.S. Government or an agency or instrumentality thereof or
  which otherwise depend directly or indirectly on the credit of the United
  States.
 
As a matter of fundamental policy, changeable only with the approval of the
holders of a majority of the outstanding shares of the Tax-Exempt Portfolio, at
least 80% of the Portfolio's annual gross income will be derived from Municipal
Instruments except under extraordinary circumstances, such as when Northern
believes that market conditions indicate that the Portfolio should adopt a
temporary defensive posture by holding uninvested cash or investing in taxable
short-term securities ("Taxable Investments"). Taxable Investments will consist
exclusively of instruments that may be purchased by the Diversified Assets
Portfolio.
 
DESCRIPTION OF SECURITIES AND COMMON INVESTMENT TECHNIQUES
 
BANK OBLIGATIONS. Domestic and foreign bank obligations in which the
Diversified Assets Portfolio may invest include certificates of deposit, bank
and deposit notes, bankers' acceptances and fixed time deposits. Such
obligations may be general obligations of the parent bank or may be limited to
the issuing branch or subsidiary by the terms of the specific obligation or by
government regulation. Total assets of a bank are determined on the basis of
the bank's most recent annual financial statements.
   
FOREIGN OBLIGATIONS. In addition to the obligations of foreign commercial banks
and foreign branches of U.S. banks, the Diversified Assets Portfolio may
acquire commercial obligations issued by Canadian corporations and Canadian
counterparts of U.S. corporations, as well as Europaper, which is U.S. dollar-
denominated commercial paper of a foreign issuer. The Diversified Assets
Portfolio may also invest in obligations issued or guaranteed by one or more
foreign governments or any of their political subdivisions, agencies or
instrumentalities. Such obligations may include debt obligations of
supranational entities, including international organizations (such as the
European Coal and Steel Community and the International Bank for Reconstruction
and Development (also known as the World Bank)) designated or supported by
governmental entities to promote economic reconstruction or development and
international banking institutions and related government agencies. Investments
by the Diversified Assets Portfolio in foreign issuer obligations will not
exceed 50% of the Portfolio's total assets measured at the time of purchase.
    
Obligations of foreign issuers acquired by the Diversified Assets Portfolio may
involve risks that are different than those of obligations of domestic issuers.
These risks include unfavorable political and economic developments, the
possible imposition of withholding taxes on interest income, possible seizure
or nationalization of foreign deposits, the possible establishment of exchange
controls, or the adoption of other foreign governmental restrictions which
might adversely affect the payment of principal and interest on such
 
                                       8
<PAGE>
 
obligations. In addition, foreign branches of U.S. banks and foreign banks may
be subject to less stringent reserve requirements and to different accounting,
auditing, reporting, and recordkeeping standards than those applicable to
domestic branches of U.S. banks and, generally, there may be less publicly
available information regarding such issuers. The Trust could also encounter
difficulties in obtaining or enforcing a judgment against a foreign issuer
(including a foreign branch of a U.S. bank).
   
VARIABLE AND FLOATING RATE INSTRUMENTS. The Portfolios may purchase rated and
unrated variable and floating rate instruments, which may have stated
maturities in excess of the Portfolios' maturity limitations subject to
applicable SEC regulations. In the case of the Diversified Assets Portfolio,
such instruments may include variable amount master demand notes that permit
the indebtedness thereunder to vary in addition to providing for periodic
adjustments in the interest rate. Unrated variable and floating rate
instruments will be determined by Northern to be of comparable quality at the
time of the purchase to rated instruments purchasable by the Portfolios. The
absence of an active secondary market with respect to particular variable and
floating rate instruments could, however, make it difficult for a Portfolio to
dispose of the instruments if the issuer defaulted on its payment obligation or
during periods that the Portfolio is not entitled to exercise its demand
rights, and the Portfolio could, for these or other reasons, suffer a loss with
respect to such instruments. Variable and floating rate instruments held by a
Portfolio will be subject to the Portfolio's 10% limitation on illiquid
investments when the Portfolio may not demand payment of the principal amount
within seven days and a reliable trading market is absent.     
   
UNITED STATES GOVERNMENT OBLIGATIONS. Each Portfolio may invest in a variety of
U.S. Treasury obligations, consisting of bills, notes and bonds, which
principally differ only in their interest rates, maturities and time of
issuance. These obligations include "stripped" securities issued by the U.S.
Treasury and recorded in the Federal Reserve book-entry record-keeping system.
The Portfolios may also invest in other securities issued or guaranteed by the
U.S. Government, its agencies and instrumentalities. Obligations of certain
agencies and instrumentalities, such as the Government National Mortgage
Association, are supported by the full faith and credit of the U.S. Treasury;
others, such as those of the Export-Import Bank of the United States, are
supported by the right of the issuer to borrow from the Treasury; others, such
as those of the Federal National Mortgage Association, are supported by the
discretionary authority of the U.S. Government to purchase the agency's
obligations; still others are supported only by the credit of the
instrumentalities. No assurance can be given that the U.S. Government would
provide financial support to its agencies or instrumentalities if it is not
obligated to do so by law. There is no assurance that these commitments will be
undertaken or complied with in the future.     
 
Securities guaranteed as to principal and interest by the U.S. Government, its
agencies 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 or an agency or instrumentality thereof,
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.
 
CUSTODIAL RECEIPTS FOR TREASURY SECURITIES. The Portfolios (other than the
Government Select Portfolio) may also purchase participations in trusts that
hold U.S. Treasury securities (such as TIGRs and CATS) where the trust
participations evidence ownership in either the future interest payments or the
future principal
 
                                       9
<PAGE>
 
payments on the U.S. Treasury obligations. These participations are normally
issued at a discount to their "face value," and may exhibit greater price
volatility than ordinary debt securities because of the manner in which their
principal and interest are returned to investors. Investments by the Government
Portfolio in such custodial receipts will not exceed 35% of the value of that
Portfolio's total assets.
 
REPURCHASE AGREEMENTS. Each Portfolio may, in accordance with its investment
objective, policies and guidelines established by the Trust's Board of
Trustees, agree to purchase portfolio securities from financial institutions
subject to the seller's agreement to repurchase them at a mutually agreed upon
date and price ("repurchase agreements"). Although the securities subject to a
repurchase agreement may bear maturities exceeding 13 months, settlement for
the repurchase agreement will never be more than one year after a Portfolio's
acquisition of the securities and normally will be within a shorter period of
time. Securities subject to repurchase agreements are held either by the
Trust's custodian or subcustodian (if any), or in the Federal Reserve/Treasury
Book-Entry System. The seller under a repurchase agreement will be required to
maintain the value of the securities subject to the agreement in an amount
exceeding the repurchase price (including accrued interest). Default by the
seller would, however, expose a Portfolio to possible loss because of adverse
market action or delay in connection with the disposition of the underlying
obligations.
   
REVERSE REPURCHASE AGREEMENTS. The Government Select, Government and
Diversified Assets Portfolios may enter into reverse repurchase agreements
which involve the sale of money market securities held by a Portfolio, with an
agreement to repurchase the securities at an agreed upon price (including
interest) and date. A Portfolio will use the proceeds of reverse repurchase
agreements to purchase other money market securities either maturing, or under
an agreement to resell, at a date simultaneous with or prior to the expiration
of the reverse repurchase agreement. A Portfolio will utilize reverse
repurchase agreements, which may be viewed as borrowings (or leverage) by the
Portfolio, when it is anticipated that the interest income to be earned from
the investment of the proceeds of the transaction is greater than the interest
expense of the reverse repurchase transaction. During the time a reverse
repurchase agreement is outstanding, the Portfolio will segregate liquid assets
having a value at least equal to the repurchase price. A Portfolio may enter
into reverse repurchase agreements with banks, brokers and dealers, and has the
authority to enter into reverse repurchase agreements in amounts not exceeding
in the aggregate one-third of the Portfolio's total assets. See "Additional
Investment Information--Investment Restrictions" in the Additional Statement.
    
SECURITIES LENDING. The Portfolios may seek additional income from time to time
by lending their portfolio securities on a short-term basis to banks, brokers
and dealers under agreements requiring that the loans be secured by collateral
in the form of cash, cash equivalents or U.S. Government securities or
irrevocable bank letters of credit maintained on a current basis equal in value
to at least the market value of the securities loaned. A Portfolio may not make
such loans in excess of 33 1/3% of the value of the Portfolio's total assets
(including the loan collateral). Loans of securities involve risks of delay in
receiving additional collateral or in recovering the securities loaned, or
possibly loss of rights in the collateral should the borrower of the securities
become insolvent.
 
FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES. Each Portfolio may purchase
when-issued securities and make contracts to purchase or sell securities for a
fixed price at a future date beyond customary settlement time. Securities
purchased 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
 
                                       10
<PAGE>
 
   
increases prior to the settlement date. Conversely, securities sold on a
delayed-delivery or forward commitment basis involve the risk that the value of
the security to be sold may increase prior to the settlement date. A Portfolio
is required to segregate liquid assets until three days prior to the settlement
date, having a value (determined daily) at least equal to the amount of the
Portfolio's purchase commitments, or to otherwise cover its position. Although
a Portfolio would generally purchase securities on a when-issued or forward
commitment basis with the intention of acquiring securities, the Portfolio may
dispose of a when-issued security or forward commitment prior to settlement if
Northern deems it appropriate to do so.     
   
INVESTMENT COMPANIES. In connection with the management of their daily cash
positions, the Portfolios may invest in securities issued by other investment
companies which invest in short-term, high-quality debt securities and which
determine their net asset value per share based on the amortized cost or penny-
rounding method of valuation ("money market funds"), and may invest in
securities issued by other types of investment companies consistent with their
investment objectives and policies. Investments by a Portfolio in other money
market funds and investment companies will be subject to the limitations of the
1940 Act as described in more detail in the Additional Statement. Although the
Portfolios do not expect to do so in the forseeable future, each Portfolio is
authorized to invest substantially all of its assets in a single open-end
investment company or series thereof with substantially the same investment
objective, policies and fundamental restrictions as the Portfolio. As a
shareholder of another investment company, a Portfolio would bear, along with
other shareholders, its pro rata portion of the other investment company's
expenses, including advisory fees. These expenses would be in addition to the
advisory fees and other expenses the Portfolio bears directly in connection
with its own operations. The Trust has been advised by its counsel that exempt-
interest dividends received by the Tax-Exempt Portfolio as a shareholder of a
regulated investment company paying such dividends will receive the same
Federal tax treatment as interest received by the Portfolio on Municipal
Instruments held by it.     
 
MUNICIPAL AND RELATED INSTRUMENTS. Municipal Instruments in which the Tax-
Exempt Portfolio may invest include debt obligations issued by or on behalf of
states, territories and possessions of the United States and their political
subdivisions, agencies, authorities and instrumentalities.
 
Municipal Instruments may be issued to obtain funds for various public
purposes, including capital improvements, the refunding of outstanding
obligations, general operating expenses, and lending to other public agencies.
Among other instruments, the Portfolio may purchase short-term Tax Anticipation
Notes, Bond Anticipation Notes, Revenue Anticipation Notes, and other forms of
short-term loans. Such notes are issued with a short-term maturity in
anticipation of the receipt of tax funds, the proceeds of bond placements or
other revenues.
 
Municipal Instruments include both "general" and "revenue" obligations. General
obligations are secured by the issuer's pledge of its full faith, credit and
taxing power for the payment of principal and interest. Revenue obligations are
payable only 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 such as lease payments from the user of the facility
being financed. Industrial development bonds are in most cases revenue
securities and are not payable from the unrestricted revenues of the issuer.
Consequently, the credit quality of an industrial revenue bond is usually
directly related to the credit standing of the private user of the facility
involved.
 
                                       11
<PAGE>
 
The Tax-Exempt Portfolio may also invest in "moral obligation" bonds, which are
normally issued by special purpose public authorities. If the issuer of a moral
obligation bond is unable to meet its debt service obligations from current
revenues, it may draw on a reserve fund, the restoration of which is a moral
commitment but not a legal obligation of the state or municipality which
created the issuer.
 
Municipal bonds with a series of maturity dates are called Serial Bonds. The
Portfolio may purchase Serial Bonds and other long-term securities provided
that they have a remaining maturity meeting the Tax-Exempt Portfolio's maturity
requirements. The Portfolio may also purchase long-term variable and floating
rate bonds (sometimes referred to as "Put Bonds") where the Portfolio obtains
at the time of purchase the right to put the bond back to the issuer or a third
party at par at least every thirteen months. Put Bonds with conditional puts
(that is, puts which cannot be exercised if the issuer defaults on its payment
obligations) will present risks that are different than those of other
Municipal Instruments because of the possibility that the Portfolio might hold
a long-term Put Bond on which a default occurs following its acquisition by the
Portfolio.
 
The Tax-Exempt Portfolio may acquire securities in the form of custodial
receipts evidencing rights to receive a specific future interest payment,
principal payment or both on certain municipal obligations. 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,"
"Municipal Certificates of Accrual on Tax-Exempt Securities" ("M-CATS") and
"Municipal Zero-Coupon Receipts." The Portfolio may also purchase certificates
of participation that, in the opinion of counsel to the issuer, are exempt from
regular Federal income tax. Certificates of participation are a type of
floating or variable rate obligation that represents interests in a pool of
municipal obligations held by a bank.
 
The Tax-Exempt Portfolio may acquire "standby commitments" with respect to the
Municipal Instruments it holds. Under a standby commitment, a dealer agrees to
purchase at the Portfolio's option specified Municipal Instruments at a
specified price. The acquisition of a standby commitment may increase the cost,
and thereby reduce the yield, of the Municipal Instruments to which the
commitment relates. The Portfolio will acquire standby commitments solely to
facilitate portfolio liquidity and does not intend to exercise its rights
thereunder for trading purposes.
 
Municipal Instruments purchased by the Tax-Exempt Portfolio may be backed by
letters of credit or other forms of credit enhancement issued by foreign (as
well as domestic) banks and other financial institutions. The credit quality of
these banks and financial institutions could, therefore, cause loss to a
Portfolio that invests in Municipal Instruments. Letters of credit and other
obligations of foreign financial institutions may involve certain risks in
addition to those of domestic obligations. (See "Foreign Obligations" above.)
 
As stated, the Tax-Exempt Portfolio expects to invest primarily in Municipal
Instruments. However, the Portfolio may from time to time hold uninvested cash
or invest a portion of its assets in Taxable Investments. The Portfolio does
not intend to invest more than 25% of the value of its total assets 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. The Portfolio may, however, invest 25% or more
of its total assets in (a) Municipal Instruments the interest upon which is
paid solely from revenues of similar projects, and (b) industrial development
obligations. In addition, although the Tax-Exempt Portfolio does not expect to
do so during normal market conditions, it may invest more than 25% of the value
of its total assets in Municipal Instruments whose issuers are in the same
state. When a substantial percentage of
 
                                       12
<PAGE>
 
   
the Portfolio's assets is invested in instruments which are used to finance
facilities involving a particular industry, whose issuers are in the same state
or which are otherwise related, there is a possibility that an economic,
business or political development affecting one such instrument would likewise
affect the other related instruments.     
   
So long as other suitable Municipal Instruments are available for investment,
the Tax-Exempt Portfolio does not intend to invest in "private activity bonds"
the interest from which may be treated as an item of tax preference to
shareholders under the Federal alternative minimum tax.     
   
The Diversified Assets Portfolio may also invest up to 5% of its net assets
from time to time in municipal instruments or other securities issued by state
and local governmental bodies when, as a result of prevailing economic,
regulatory or other circumstances, the yield of such securities, on a pre-tax
basis, is comparable to that of other permitted short-term taxable investments.
Dividends paid on such investments will be taxable to shareholders.     
   
ISSUER DIVERSIFICATION. In accordance with current SEC regulations, each
Portfolio intends to limit investments in the securities of any single issuer
(excluding cash, cash items, certain repurchase agreements, U.S. Government
securities or securities of other investment companies) to not more than 5% of
the value of its total assets at the time of purchase, except that (a) 25% of
the value of the total assets of each Portfolio may be invested in the
securities of any one issuer for a period of up to three Business Days; and (b)
securities subject to certain unconditional guarantees are subject to different
diversification requirements as described in the Additional Statement. In
addition, the Portfolios will limit their investments in securities that are
not First Tier Securities as prescribed by SEC regulations.     
   
DERIVATIVE INSTRUMENTS. Each Portfolio may also purchase certain "derivative"
instruments. "Derivative" instruments are instruments that derive value from
the performance of underlying assets, interest rates or indices, and include
(but are not limited to) various structured debt obligations (including certain
variable and floating rate instruments). Derivative instruments present, to
varying degrees, market risk that the performance of the underlying assets,
interest rates or indices will decline; credit risk that the dealer or other
counterparty to the transaction will fail to pay its obligations; volatility
risk that, if interest rates change adversely, the value of the derivative
instrument will decline more than the assets, rates or indices on which it is
based; liquidity risk that a Portfolio will be unable to sell a derivative
instrument when it wants because of lack of market depth or market disruption;
pricing risk that the value of a derivative instrument will not correlate
exactly to the value of the underlying assets, rates or indices on which it is
based; and operations risk that loss will occur as a result of inadequate
systems and controls, human error or otherwise. Some derivative instruments are
more complex than others, and for those instruments that have been developed
recently, information is lacking regarding their actual performance over
complete market cycles. Northern will evaluate the risks presented by the
derivative instruments purchased by the Portfolios, and will determine, in
connection with its day-to-day management of the Portfolios, how they will be
used in furtherance of the Portfolios' investment objectives. It is possible,
however, that Northern's evaluations will prove to be inaccurate or incomplete
and, even when accurate and complete, it is possible that the Portfolios will,
because of the risks discussed above, incur loss as a result of their
investments in derivative instruments.     
 
ILLIQUID OR RESTRICTED SECURITIES. A Portfolio will not invest more than 10% of
its net assets in securities which are illiquid, including repurchase
agreements and time deposits that do not provide for payment to the Trust
 
                                       13
<PAGE>
 
   
within seven days after notice and certificates of participation for which
there is no readily available secondary market and certain securities which are
subject to trading restrictions because they are not registered under the
Securities Act of 1933 (the "1933 Act").     
   
If otherwise consistent with their investment objectives and policies, the
Portfolios may purchase commercial paper issued pursuant to Section 4(2) of the
1933 Act and securities that are not registered under the 1933 Act but can be
sold to "qualified institutional buyers" in accordance with Rule 144A under the
1933 Act. These securities will not be considered illiquid so long as Northern
determines, under guidelines approved by the Trust's Board of Trustees, that an
adequate trading market exists. This practice could increase the level of
illiquidity during any period that qualified institutional buyers become
uninterested in purchasing these securities.     
 
MISCELLANEOUS. Although the Portfolios will generally not seek profits through
short-term trading, each Portfolio may dispose of any portfolio security prior
to its maturity if, on the basis of a revised credit evaluation of the issuer
or other considerations, Northern believes such disposition is advisable.
Subsequent to its purchase, a portfolio security may be assigned a lower rating
or cease to be rated. Such an event would not necessarily require the
disposition of the security, if the continued holding of the security is
determined to be in the best interest of the Portfolio and its shareholders.
 
In determining the creditworthiness of the issuers of portfolio securities that
may be purchased and held by the Portfolios, Northern gathers and reviews
historical financial data and, through the use of a proprietary software
computer program, analyzes and attempts to assess the fundamental strengths and
weaknesses of individual issuers, industries and market sectors. Exposure
limits are established by Northern for each security in conformance with the
objectives and policies stated in this Prospectus, and are thereafter adjusted
periodically in response to changes in relevant credit factors.
          
Pursuant to an SEC order, each Portfolio may engage in principal transactions
effected in the ordinary course of business with Goldman Sachs.     
 
INVESTMENT RESTRICTIONS
 
The Portfolios are subject to certain investment restrictions which, as
described in more detail in the Additional Statement, are fundamental policies
that cannot be changed without the approval of a majority of the outstanding
shares of a Portfolio. Each Portfolio will limit its investments so that less
than 25% of the Portfolio's total assets will be invested in the securities of
issuers in any one industry (with certain limited exceptions). Each Portfolio
may borrow money from banks for temporary or emergency purposes or to meet
redemption requests, provided that the Portfolio maintains asset coverage of at
least 300% for all such borrowings.

                               TRUST INFORMATION
 
BOARD OF TRUSTEES
 
The business and affairs of the Trust and each Portfolio are managed under the
direction of the Trust's Board of Trustees. The Additional Statement contains
the name of each Trustee and background information regarding the Trustees.
 
INVESTMENT ADVISER, TRANSFER AGENT AND CUSTODIAN
 
Northern, which has offices at 50 S. LaSalle Street, Chicago, Illinois 60675,
serves as investment adviser, transfer agent and custodian for each Portfolio.
As transfer agent, Northern performs various shareholder servicing functions,
and any shareholder inquiries should be directed to it.
 
Northern, a member of the Federal Reserve System, is an Illinois state-
chartered commercial bank and the principal subsidiary of Northern Trust
Corporation, a bank holding company. Northern was formed in 1889 with
capitalization of $1 million. As of December 31, 1997, Northern Trust
Corporation and its subsidiaries had approximately $25.3 billion in assets,
$16.4 billion in deposits and employed over 7,553 persons.
   
Northern and its affiliates administered in various capacities (including as
master trustee, investment manager or custodian) approximately $1 trillion of
assets as of December 31, 1997, including approximately $196.5 billion of
assets for which Northern and its affiliates had investment management
responsibility.     
 
Under its Advisory Agreement with the Trust, Northern, subject to the general
supervision of the Trust's Board of Trustees, is responsible for making
investment decisions for the Portfolios and placing purchase and sale orders
for portfolio securities. Northern is also responsible for monitoring and
preserving the records required to be maintained under the regulations of the
SEC (with certain exceptions unrelated to its activities for the Trust). As
compensation for its advisory services and its assumption of related expenses,
Northern is entitled to a fee, computed daily and payable monthly, at an annual
rate of .25% of the average daily net assets of each Portfolio.
 
For serving as investment adviser during the fiscal year ended November 30,
1997, Northern earned fees paid by the Government Portfolio, the Diversified
Assets Portfolio and the Tax-Exempt Portfolio at the rate of .25% (per annum)
of each Portfolio's average daily net assets. For serving as investment adviser
during the fiscal year ended November 30, 1997, Northern earned fees (after
waivers) paid by the Government Select Portfolio at the rate of .10% (per
annum) of its average daily net assets.
   
Northern also receives compensation as the Trust's custodian and transfer agent
under separate agreements. The fees payable by the Portfolios for these
services are described in this Prospectus under "Summary of Expenses" and in
the Additional Statement. Different transfer agency fees are payable with
respect to a Portfolios' different share classes.     
          
YEAR 2000     
   
Like every other business dependent upon computerized information processing,
Northern Trust Corporation ("Northern Trust") must deal with "Year 2000"
issues, which stem from using two digits to reflect the year in computer
programs and data. Computer programmers and other designers of equipment that
use     
 
                                       15
<PAGE>
 
   
microprocessors have long abbreviated dates by eliminating the first two digits
of the year under the assumption that those two digits will always be 19. As
the Year 2000 approaches, many systems may be unable to accurately process
certain date-based information, which could cause a variety of operational
problems for businesses.     
   
Northern Trust's data processing software and hardware provide essential
support to virtually all of its businesses, including the units that provide
services to the Trust, so successfully addressing Year 2000 issues is of the
highest importance. Failure to complete renovation of the critical systems used
by Northern on a timely basis could have a materially adverse effect on its
ability to provide such services -- as could Year 2000 problems experienced by
others. Although the nature of the problem is such that there can be no
complete assurance it will be successfully resolved, Northern Trust has
indicated that a renovation and risk mitigation program is well under way and
that it has a dedicated Year 2000 Project Team whose members have significant
systems development and maintenance experience. Northern Trust's Year 2000
project includes a comprehensive testing plan. Northern Trust has advised the
Trust that it expects to complete work on its critical systems by December 31,
1998, so that testing with outside parties may be conducted during 1999.     
   
Northern Trust also will have a program to monitor and assess the efforts of
other parties. However, it cannot control the success of those efforts.
Contingency plans are being established where appropriate to provide Northern
Trust with alternatives in case these entities experience significant Year 2000
difficulties which impact Northern Trust.     
 
ADMINISTRATOR AND DISTRIBUTOR
 
Goldman Sachs, 85 Broad Street, New York, New York 10004, acts as administrator
and distributor for the Portfolios. Subject to the limitations described below,
as compensation for its administrative services (which include supervision with
respect to the Trust's non-investment advisory operations) and the assumption
of related expenses, Goldman Sachs is entitled to a fee from each Portfolio,
computed daily and payable monthly, at an annual rate of .10% of the average
daily net assets of each Portfolio. No compensation is payable by the Trust to
Goldman Sachs for its distribution services.
   
In addition, Goldman Sachs has agreed that it will reimburse each Portfolio's
expenses (including the fees payable to Goldman Sachs as administrator, but
excluding the fees payable to Northern for its duties as investment adviser and
transfer agent, payments under the service plan for the Portfolios' Premier and
Service Share classes and extraordinary expenses such as interest, taxes and
indemnification expenses) which exceed on an annualized basis .10% of such
Portfolio's average daily net assets for any fiscal year. In addition, as of
the date of this Prospectus, Northern will continue to reduce its advisory fee
for the Government Select Portfolio. The result of these reimbursements and fee
reductions will be to increase the yields of the Portfolios during the periods
for which the reimbursements and reductions are made.     
 
SERVICE PLAN
   
Pursuant to a Service Plan ("Service Plan") adopted by the Board of Trustees of
the Trust with respect to the Premier Shares, banks, trust companies and other
institutions and organizations including Northern and its affiliates
("Servicing Agents") may enter into agreements ("Servicing Agreements") under
which they will render (or arrange for the rendering of) administrative support
services and personal and account maintenance services for Premier Share
investors for the fees described below ("Service Fees").

Administrative support services to be provided by Servicing Agents, which are
described more fully in the Additional Statement, may include establishing and
maintaining individual accounts and records with respect to Premier Shares
owned by their Customers (as defined below), processing purchase, redemption
and exchange orders for their Customers, placing net purchase and redemption
orders with Northern acting as the Trust's transfer agent and providing cash
management or sweep accounts and similar programs and services for their
Customers. For these administrative support services, the Service Plan provides
for the payment of fees to Servicing Agents at an annual rate of up to .25% of
the average daily net asset value of the Premier Shares beneficially owned by
their Customers. Personal and account maintenance services provided under the
Service Plan, which are also described more fully in the Additional Statement,
may include providing information to investors regarding the Portfolios or
relating to the status of their accounts and acting as liaison between
investors and the Trust. For these liaison services, the Service Plan provides
for the additional payment of fees to Servicing Agents at an annual rate of up
to .25% of the average daily net asset value of Premier Shares beneficially
owned by their Customers. The Service Plan also provides for the payment of
fees to Northern, Goldman Sachs or other institutions at an annual rate of up
to .08% of the average daily net asset value of Premier Shares serviced by such
institutions for ongoing consulting services, technology and systems support
services relating to cash management or sweep account services. All fees
payable under the Service Plan are borne solely by Premier Shares and not by
the Portfolios' other share classes.     
   
Conflict of interest restrictions may apply to the receipt of compensation by
the Trust to a Servicing Agent in connection with the investment of fiduciary
funds in Premier Shares. Banks and other institutions regulated by the Office
of Comptroller of the Currency, Board of Governors of the Federal Reserve
System and state banking commissions, and investment advisers and other money
managers subject to the jurisdiction of the SEC, the Department of Labor or
state securities commissions, are urged to consult legal counsel before
entering into Servicing Agreements.     
 
EXPENSES
   
Except as set forth above and in the Additional Statement under "Additional
Trust Information," each Portfolio is responsible for the payment of its
expenses. Such expenses include, without limitation, the fees and expenses
payable to Northern and Goldman Sachs, fees for the registration or
qualification of Portfolio shares under Federal or state securities laws,
expenses of the organization of the Portfolio, taxes, 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 Trust for violation of any law, legal,
tax and auditing fees and expenses, Service Fees, expenses of preparing and
printing prospectuses, statements of additional information, proxy materials,
reports and notices and the printing and distributing of the same to the
Trust's shareholders and regulatory authorities, compensation and expenses of

                                   INVESTING
 
PURCHASE OF PREMIER SHARES
   
Premier Shares are offered to Northern, its affiliates and other institutions
and organizations, including certain defined contribution plans having at least
$30 million in assets or annual contributions of at least $5 million (the
"Institutions"), acting on behalf of their customers, clients, employees,
participants and others (the "Customers"). Premier Shares of the Portfolios are
sold on a continuous basis by the Trust's distributor, Goldman Sachs, to
Institutions that have agreed to render (or arrange for the rendering of)
administration support and shareholder liaison services to Customers pursuant
to a Servicing Agreement and either maintain certain institutional accounts
with Northern or its affiliates or invest an aggregate of at least $5 million
in one or more Portfolios of the Trust. See "Trust Information--Servicing Plan"
above. The Trust has established procedures for purchasing Premier Shares in
order to accommodate different types of Institutions.     
   
PURCHASE OF PREMIER SHARES THROUGH INSTITUTIONAL ACCOUNTS. Any Institution
maintaining an institutional account at Northern or an affiliate may make
purchases through such institutional account either by directing automatic
investment of cash balances in excess of certain agreed upon amounts or by
directing investments from time to time on a non-automatic basis. The nature of
an Institution's relationship with Northern or an affiliate will determine
whether the Institution maintains an institutional account as well as the
procedures available for purchases. Institutions should contact Northern or an
affiliate for further information in this regard. There is no minimum initial
investment for Institutions that maintain institutional accounts with Northern
or its affiliates.     
 
PURCHASE OF PREMIER SHARES DIRECTLY FROM THE TRUST. An Institution that
purchases Premier Shares directly may do so by means of one of the following
procedures, provided it makes an aggregate minimum initial investment of $5
million in one or more Portfolios of the Trust:
     
  PURCHASE BY MAIL. An Institution desiring to purchase Premier Shares of a
  Portfolio by mail should mail a check or Federal Reserve draft payable to
  the specific Portfolio together with a completed and signed new account
  application to The Benchmark Funds, c/o The Northern Trust Company, P.O.
  Box 75943, Chicago, Illinois 60675-5943. An application will be incomplete
  if it does not include a corporate resolution with the corporate seal and
  secretary's certification, or other acceptable evidence of authority. If an
  Institution desires to purchase the Premier Shares of more than one
  Portfolio, the Institution should send a separate check for each Portfolio.
  All checks must be payable in U.S. dollars and drawn on a bank located in
  the United States. A $20 charge will be imposed if a check does not clear.
  The proceeds of redemptions of shares purchased by check may be delayed up
  to 15 days to allow the Trust to determine that the check has cleared and
  been paid. Cash and third party checks are not acceptable for the purchase
  of Premier Shares.     
 
  PURCHASE BY TELEPHONE. An Institution desiring to purchase Premier Shares
  of a Portfolio by telephone should call Northern acting as the Trust's
  transfer agent ("Transfer Agent") at 1-800-637-1380. Please be prepared to
  identify the name of the Portfolio with respect to which Premier Shares are
  to be purchased and the manner of payment. Please indicate whether a new
  account is being established or an additional payment is being made to an
  existing account. If an additional payment is being made to an
 
                                       18
<PAGE>
 
  existing account, please provide the Institution's name and Portfolio
  Account Number. Purchase orders are effected upon receipt by the Transfer
  Agent of Federal funds or other immediately available funds in accordance
  with the terms set forth below.
 
  PURCHASE BY WIRE OR ACH TRANSFER. An Institution desiring to purchase
  Premier Shares of a Portfolio by wire or ACH Transfer should call the
  Transfer Agent at 1-800-637-1380 for instructions if it is not making an
  additional payment to an existing account. An Institution that wishes to
  add to an existing account should wire Federal funds or effect an ACH
  Transfer to:
 
                      The Northern Trust Company
                      Chicago, Illinois
                      ABA Routing No. 0710-00152
                      (Reference 10 Digit Portfolio Account Number)
                         
                      (Reference Shareholder's Name)     
 
  For other information concerning requirements for the purchase of Premier
  Shares, call the Transfer Agent at 1-800-637-1380.
   
EFFECTIVE TIME OF PURCHASES. Except as provided below under "Miscellaneous," a
purchase order for Premier Shares placed with the Transfer Agent by 1:00 p.m.,
Chicago time, on a Business Day (as defined under "Miscellaneous") will be
effected on that Business Day at the net asset value next determined on that
day with respect to a Portfolio, provided that the Transfer Agent receives the
purchase price in Federal funds or other immediately available funds prior to
1:00 p.m., Chicago time, on the same Business Day such order is received.
Orders received after 1:00 p.m. on a Business Day will be effected at the net
asset value next determined on the following Business Day, provided that
payment is received as provided herein. Purchase orders received on a non-
Business Day will not be executed until the following Business Day in
accordance with the foregoing procedures. An order generated pursuant to an
automatic investment direction of an Institution that has an institutional
account with Northern or its affiliates will normally be placed either on the
Business Day that funds are available in such account or on the first Business
Day thereafter, depending upon the terms of the Institution's automatic
investment arrangements. Shares of a Portfolio are entitled to the dividends
declared by the Portfolio beginning on the Business Day the purchase order is
executed.     
 
MISCELLANEOUS PURCHASE INFORMATION. Shares are purchased without a sales charge
imposed by the Trust. The minimum initial investment is $5 million for
Institutions that invest directly in one or more investment portfolios of the
Trust. The Trust reserves the right to waive this minimum and to determine the
manner in which the minimum investment is satisfied. There is no minimum for
subsequent investments.
 
Institutions intending to place a purchase order of $5 million or more directly
with the Trust through the Transfer Agent are requested to give advance notice
to the Transfer Agent no later than 11:00 a.m. Chicago Time on a Business Day
in order to assist in the processing of the order.
 
See "Miscellaneous" below for information on when the Trust may advance the
time by which purchase requests must be received.
 
Institutions may impose minimum investment and other requirements on Customers
purchasing shares through them. Depending on the terms governing the particular
account, Institutions may impose account
 
                                       19
<PAGE>
 
   
charges such as asset allocation fees, account maintenance fees, compensating
balance requirements or other charges based upon account transactions, assets
or income, which will have the effect of reducing the net return on an
investment in a Portfolio. In addition, Institutions will enter into Servicing
Agreements whereby they will perform (or arrange to have performed) various
administrative support services and shareholder liaison services for Customers
who are the beneficial owners of Premier Shares. These services may include
providing sweep accounts or similar programs to their Customers. See "Trust
Information--Service Plan." The exercise of voting rights and the delivery to
Customers of shareholder communications from the Trust will be governed by the
Customers' account agreements with the Institutions. Customers should read this
Prospectus in connection with any relevant agreement describing the services
provided by an Institution and any related requirements and charges, or contact
the Institution at which the Customer maintains its account for further
information.     
 
Institutions that purchase shares on behalf of Customers are responsible for
transmitting purchase orders to the Transfer Agent and delivering required
Federal funds on a timely basis. An Institution will be responsible for all
losses and expenses of a Portfolio as a result of a check that does not clear,
an ACH transfer that is rejected, or any other failure to make payment in the
time and manner described above, and Northern may redeem shares from an account
it maintains to protect the Portfolio and Northern against loss. The Trust
reserves the right to reject any purchase order. In those cases in which an
Institution pays for shares by check, Federal funds will generally become
available two Business Days after a purchase order is received. Federal
regulations require that the Transfer Agent be furnished with a taxpayer
identification number upon opening or reopening an account. Purchase orders
without such a number or an indication that a number has been applied for will
not be accepted. If a number has been applied for, the number must be provided
and certified within sixty days of the date of the order.
 
Payment for shares of a Portfolio may, in the discretion of Northern, be made
in the form of securities that are permissible investments for the Portfolio.
For further information about the terms of such purchases, see the Additional
Statement.
 
In the interests of economy and convenience, certificates representing shares
of the Portfolios are not issued.
 
Institutions investing in the Portfolios on behalf of their Customers should
note that state securities laws regarding the registration of dealers may
differ from the interpretations of Federal law and such institutions may be
required to register as dealers pursuant to state law.
   
Northern may, at its own expense, provide compensation to certain dealers and
other financial intermediaries who provide services to their Customers who
invest in the Trust or whose Customers purchase significant amounts of shares
of a Portfolio. The amount of such compensation may be made on a one-time
and/or periodic basis, and may represent all or a portion of the annual fees
that are earned by Northern as investment adviser to such Portfolio (after
adjustments) and are attributable to shares held by such Customers. Such
compensation will not represent an additional expense to the Trust or its
shareholders, since it will be paid from assets of Northern or its affiliates.
       
REDEMPTION OF PREMIER SHARES     
   
Institutions may redeem shares of a Portfolio through procedures established by
Northern and its affiliates in connection with the requirements of their
institutional accounts or through procedures set forth herein with respect to
Institutions that invest directly.     
 
                                       20
<PAGE>
 
   
REDEMPTION OF SHARES THROUGH INSTITUTIONAL ACCOUNTS. Institutions may redeem
shares in their institutional accounts at Northern or its affiliates. For
Institutions that participate in an automatic investment service described
above under "Purchase of Premier Shares," Northern or its affiliates will
calculate on each Business Day the number of shares that need to be redeemed in
order to bring the Institution's account up to any agreed upon minimum amount.
Redemption requests on behalf of an Institution will normally be placed either
on the Business Day the redemption amount is calculated or on the first
Business Day thereafter, depending upon the terms of the Institution's
automatic investment arrangements. In the latter case, however, Northern or its
affiliates normally will provide funds by provisionally crediting the
institutional account of the Institution on the Business Day on which the
calculation is made. The nature of an Institution's relationship with Northern
or an affiliate will determine whether the Institution maintains an
"institutional account" as well as the procedures available for redemptions.
Institutions should contact Northern or an affiliate for further information in
this regard.     
 
REDEMPTION OF SHARES DIRECTLY. Institutions that purchase shares directly from
the Trust through the Transfer Agent may redeem all or part of their Portfolio
shares in accordance with the procedures set forth below.
 
  REDEMPTION BY MAIL. An Institution may redeem shares by sending a written
  request to The Benchmark Funds, c/o The Northern Trust Company, P.O. Box
  75943, Chicago, Illinois 60675-5943. Redemption requests must be signed by
  a duly authorized person, and must state the number of shares or the dollar
  amount to be redeemed and identify the Portfolio Account Number. See "Other
  Requirements."
 
  REDEMPTION BY TELEPHONE. An Institution may redeem shares by placing a
  redemption order by telephone by calling the Transfer Agent at 1-800-637-
  1380. During periods of unusual economic or market changes, telephone
  redemptions may be difficult to implement. In such event, shareholders
  should follow procedures outlined above under "Redemption by Mail."
 
  REDEMPTION BY WIRE. If an Institution has given authorization for expedited
  wire redemption, shares can be redeemed and the proceeds sent by Federal
  wire transfer to a single previously designated bank account. The minimum
  amount which may be redeemed by this method is $10,000. The Trust reserves
  the right to change or waive this minimum or to terminate the wire
  redemption privilege. See "Other Requirements."
 
  TELEPHONE PRIVILEGE. An Institution that has notified the Transfer Agent in
  writing of the Institution's election to redeem or exchange shares by
  placing an order by telephone may do so by calling the Transfer Agent at
  1-800-637-1380. Neither the Trust nor its Transfer Agent will be
  responsible for the authenticity of instructions received by telephone that
  are reasonably believed to be genuine. To the extent that the Trust fails
  to use reasonable procedures to verify the genuineness of telephone
  instructions, it or its service providers may be liable for such
  instructions that prove to be fraudulent or unauthorized. In all other
  cases, the shareholder will bear the risk of loss for fraudulent telephone
  transactions. However, the Transfer Agent has adopted procedures in an
  effort to establish reasonable safeguards against fraudulent telephone
  transactions. The proceeds of redemption orders received by telephone will
  be sent by check, by wire or by transfer pursuant to proper instruments.
  All checks will be made payable to the shareholder of record and mailed
  only to the shareholder's address of record. See "Other Requirements."
  Additionally, the Transfer Agent utilizes recorded lines for telephone
  transactions and retains such tape
 
                                       21
<PAGE>
 
  recordings for six months, and will request a form of identification if
  such identification has been furnished to the Transfer Agent or the Trust.
     
  OTHER REQUIREMENTS. A change of wiring instructions and a change of the
  address of record may be effected only by a written request to the Transfer
  Agent accompanied by (i) a corporate resolution which evidences authority
  to sign on behalf of the Institution (including the corporate seal and
  secretary's certification), (ii) a signature guarantee by a financial
  institution that is a participant in the Stock Transfer Agency Medallion
  Program ("STAMP") in accordance with rules promulgated by the SEC (a
  signature notarized by a notary public is not acceptable) or (iii) such
  other means or evidence of authority as may be acceptable to the Transfer
  Agent. A redemption request by mail will not be effective unless signed by
  a person authorized by the corporate resolution or other acceptable
  evidence of authority on file with the Transfer Agent.     
   
EXCHANGE PRIVILEGE. Institutions and, to the extent permitted by their account
agreements, Customers, may, after appropriate prior authorization, exchange
Premier Shares of a Portfolio having a value of at least $1,000 for Premier
Shares of other Portfolios to which the Institution or Customer maintains an
existing account with an identical title.     
   
Exchanges will be effected by a redemption of shares of the Portfolio held and
the purchase of shares of the portfolio acquired. Customers of Institutions
should contact their Institutions for further information regarding the Trust's
exchange privilege and Institutions should contact the Transfer Agent as
appropriate. Customers and Institutions exercising the exchange privilege
should read the relevant prospectus prior to making an exchange. The Trust
reserves the right to modify or terminate the exchange privilege at any time
upon 60 days' written notice to shareholders of record and to reject any
exchange request. Exchanges are only available in states where an exchange can
legally be made.     
   
EFFECTIVE TIME OF REDEMPTIONS AND EXCHANGES. Redemption orders of Portfolio
shares are effected at the net asset value per share next determined after
receipt in good order by the Transfer Agent. Good order means that the request
includes the following: the account number and Portfolio name; the amount of
the transaction (as specified in dollars or shares); and the signature of a
duly authorized person (except for telephone and wire redemptions). See
"Investing--Redemption of Premier Shares--Other Requirements." Exchange orders
are effected at the net asset value per share next determined after receipt in
good order by the Transfer Agent. Payment for redeemed shares for which a
redemption order is received by Northern with respect to an institutional
account it maintains or the Transfer Agent as of 1:00 p.m., Chicago time, on a
Business Day normally will be made in Federal funds or other immediately
available funds wired or sent by check to the redeeming shareholder or, if
selected, the shareholder's institutional account with Northern on that
Business Day. Redemption orders received after 1:00 p.m. will be effected the
next Business Day. Proceeds for redemption orders received on a non-Business
Day will normally be sent on the next Business Day after receipt in good order.
    
MISCELLANEOUS REDEMPTION AND EXCHANGE INFORMATION. All redemption proceeds will
be sent by check unless Northern or the Transfer Agent is directed otherwise.
The ACH system may be utilized for payment of redemption proceeds. Redemption
of shares may not be effected if a shareholder has failed to submit a completed
and properly executed (with corporate resolution or other acceptable evidence
of authority) new account application. Institutions intending to place exchange
and redemption orders for same day proceeds
 
                                       22
<PAGE>
 
of $5 million or more directly with the Trust through the Transfer Agent are
requested to give advance notice to the Transfer Agent no later than 11:00 a.m.
Chicago Time on a Business Day. The proceeds of redemptions of shares purchased
by check may be delayed up to 15 days to allow the Trust to determine that the
check has cleared and been paid. The Trust reserves the right to defer
crediting, sending or wiring redemption proceeds for up to seven days after
receiving a redemption order if, in its judgment, an earlier payment could
adversely affect a Portfolio.
 
See "Miscellaneous" below for information on when the Trust may advance the
time by which redemption and exchange requests must be received.
 
The Trust may require any information reasonably necessary to ensure that a
redemption has been duly authorized. Dividends on shares are earned through and
including the day prior to the day on which they are redeemed.
 
It is the responsibility of Institutions acting on behalf of Customers to
transmit redemption orders to the Transfer Agent and to credit Customers'
accounts with the redemption proceeds on a timely basis. If a Customer has
agreed with a particular Institution to maintain a minimum balance in his
account at such Institution and the balance in such account falls below that
minimum, such Customer may be obliged to redeem all or part of his shares to
the extent necessary to maintain the required minimum balance.
 
DISTRIBUTIONS
 
Shareholders of each Portfolio are entitled to dividends and distributions
arising from the net income and capital gains, if any, earned on investments
held by the particular Portfolio. Dividends from each Portfolio's net income
are declared daily as a dividend to shareholders of record at the close of
business on the days the dividends are declared (or 3:00 p.m., Chicago time, on
non-Business Days).
 
Net income of the Premier Shares of each Portfolio includes interest accrued on
the assets of such Portfolio and allocated to its Premier Shares less the
estimated expenses charged to the Premier Shares of such Portfolio. Net
realized short-term capital gains of each Portfolio will be distributed at
least annually. The Portfolios do not expect to realize net long-term capital
gains.
   
Dividends declared during a calendar month will be paid as soon as practicable
following the end of the month, except that such dividends will be paid
promptly upon a total redemption of shares in any account not subject to a
standing order for the purchase of shares. All distributions are paid by each
Portfolio in cash or are automatically reinvested (without any sales charge) in
additional Premier Shares of the same Portfolio. Arrangements may be made for
the crediting of such distributions to a shareholder's account with Northern,
its affiliates or its correspondent banks.     
 
TAXES
 
Management of the Trust intends that each Portfolio will qualify as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended (the "Code") as long as such qualification is in the best interest of
the Portfolio's shareholders. Such qualification generally relieves each
Portfolio of liability for Federal income taxes to the extent its earnings are
distributed in accordance with the Code, but shareholders,
 
                                       23
<PAGE>
 
unless otherwise exempt, will pay income taxes on amounts so distributed
(except distributions that constitute "exempt-interest dividends" or that are
treated as a return of capital). Dividends paid from net short-term capital
gains are treated as ordinary income dividends. None of the Portfolios'
distributions will be eligible for the corporate dividends received deduction.
 
The Tax-Exempt Portfolio intends to pay substantially all of its dividends as
"exempt-interest dividends." Investors in the Portfolio should note, however,
that taxpayers are required to report the receipt of tax-exempt interest and
"exempt-interest dividends" on their Federal income tax returns and that in two
circumstances such amounts, while exempt from regular Federal income tax, are
taxable to persons subject to alternative minimum taxes. First, tax-exempt
interest and "exempt-interest dividends" derived from certain private activity
bonds issued after August 7, 1986 generally will constitute an item of tax
preference for corporate and noncorporate taxpayers in determining alternative
minimum tax liability. Second, all tax-exempt interest and "exempt-interest
dividends" must be taken into account by corporate taxpayers in determining
certain adjustments for alternative minimum tax purposes. Shareholders who are
recipients of Social Security Act or Railroad Retirement Act benefits should
note that tax-exempt interest and "exempt-interest dividends" will be taken
into account in determining the taxability of their benefit payments. To the
extent, if any, that dividends paid by the Tax-Exempt Portfolio to its
shareholders are derived from taxable interest or from capital gains, such
dividends will be subject to Federal income tax, whether received in cash or
reinvested in additional shares.
 
The Tax-Exempt Portfolio will determine annually the percentages of its net
investment income which are exempt from the regular Federal income tax, which
constitute an item of tax preference for purposes of the Federal alternative
minimum tax, and which are fully taxable and will apply such percentages
uniformly to all distributions declared from net investment income during that
year. These percentages may differ significantly from the actual percentages
for any particular day.
 
The Trust will send written notices to shareholders annually regarding the tax
status of distributions made by each Portfolio. Dividends declared in October,
November or December of any year payable to shareholders of record on a
specified date in those months will be deemed for Federal tax purposes to have
been paid by a Portfolio and to have been received by the shareholders on
December 31 of that year, if the dividends are actually paid during the
following January.
 
The foregoing discussion is only a brief summary of some of the important tax
considerations generally affecting the Portfolios and their shareholders and is
not intended as a substitute for careful tax planning. Accordingly, investors
should consult their tax advisers with specific reference to their own Federal,
state and local tax situation. In particular, although the Government Select
Portfolio intends to invest primarily in U.S. Government securities the
interest on which is generally exempt from state income taxation, an investor
should consult his or her own tax adviser to determine whether distributions
from the Portfolio are exempt from state income taxation in the investor's own
situation. Similarly, dividends paid by the Portfolios may be taxable to
investors under state or local law as dividend income even though all or a
portion of such dividends may be derived from interest on obligations which, if
realized directly, would be exempt from such income taxes. Future legislative
or administrative changes or court decisions may materially affect the tax
consequences of investing in one or more of the Portfolios.
 
                                       24
<PAGE>
 
                                NET ASSET VALUE
   
The net asset value per share of each Portfolio for purposes of purchases and
redemptions is calculated by Northern as of 3:00 p.m., Chicago time,
immediately after the declaration of net income earned by shareholders of
record, on each Business Day (as defined below under "Miscellaneous"), except
for days during which no shares are tendered to the Portfolio for redemption
and no orders to purchase or sell shares are received by the Portfolio and
except for days on which there is an insufficient degree of trading in the
Portfolio's securities for changes in the value of such securities to
materially affect the net asset value per share. The time at which the net
asset value per share of a Portfolio is calculated may be advanced on days on
which Northern or the securities markets close early. See "Miscellaneous"
below. Net asset value per Premier Share of each Portfolio is calculated by
adding the value of all securities and other assets belonging to the Portfolio
that are allocated to the Premier Shares, subtracting the liabilities charged
to the Premier Shares and dividing by the number of Premier Shares of the
Portfolio outstanding.     
 
In seeking to maintain a net asset value of $1.00 per share with respect to
each Portfolio for purposes of purchases and redemptions, the Trust values the
portfolio securities held by a Portfolio pursuant to the amortized cost
method. Under this method, 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 of maturity. See "Amortized Cost
Valuation" in the Additional Statement. There can be no assurance that a
Portfolio will be able at all times to maintain a net asset value per share of
$1.00.
 
                            PERFORMANCE INFORMATION
 
From time to time the Portfolios may advertise the "yields" and "effective
yields", and the Government Select Portfolio and Tax-Exempt Portfolio may
advertise the "tax-equivalent yields", of Premier Shares. These yield figures
will fluctuate, are based on historical earnings and are not intended to
indicate future performance. "Yield" refers to the net investment income
generated by an investment in the Portfolio over a seven-day period identified
in the advertisement. This net investment income is then "annualized." That
is, the amount of net investment income generated by the investment during
that week is assumed to be generated each week over a 52-week period and is
shown as a percentage of the investment. "Effective yield" is calculated
similarly but, when annualized, the net investment income earned by an
investment in the Portfolio is assumed to be reinvested. The "effective yield"
will be slightly higher than the "yield" because of the compounding effect of
this assumed reinvestment. The "tax-equivalent yield" demonstrates the level
of taxable yield necessary to produce an after-tax yield equivalent to a
Portfolio's tax-free yield. It is calculated by taking that portion of the
seven-day "yield" which is tax-exempt and adjusting it to reflect the tax
savings associated with a stated tax rate. The "tax-equivalent yield" will
always be higher than the Portfolio's yield.
 
The Portfolios' yields may not provide a basis for comparison with bank
deposits and other investments which provide a fixed yield for a stated period
of time. Yield will be affected by portfolio quality, composition, maturity,
market conditions and the level of the Portfolio's operating expenses.
 
Each Portfolio may also quote from time to time the total return on its
Premier Shares in accordance with SEC regulations.

                                  ORGANIZATION
   
Each Portfolio is a series of The Benchmark Funds, which was formed as a
Delaware business trust on July 1, 1997 under an Agreement and Declaration of
Trust. The Portfolios were formerly series of The Benchmark Funds, a
Massachusetts business trust, and were reorganized into the Trust on March 31,
1998. As of the date of this Prospectus, the Trust has created eighteen
separate series of shares of beneficial interest representing interests in
eighteen investment portfolios, four of which are described in this Prospectus;
the other series of shares are described in a separate prospectus. The business
and affairs of the Trust are managed by or under the direction of its Board of
Trustees. The Declaration of Trust of the Trust authorizes the Board of
Trustees to classify or reclassify any unissued shares into additional series
or classes within a series. Pursuant to such authority, the Board of Trustees
has classified three classes of shares in each Portfolio: the Shares, Service
Shares and Premier Shares. This Prospectus relates only to Premier Shares of
the Portfolios described herein.     
   
Each share of a Portfolio is without par value, represents an equal
proportionate interest in that Portfolio with each other share of its class in
that Portfolio and is entitled to such dividends and distributions earned on
such Portfolio's assets as are declared in the discretion of the Board of
Trustees. Shares of each class bear their pro rata portion of all operating
expenses paid by a Portfolio, except transfer agency fees and amounts payable
under the Service Plan relating to Service Shares and Premier Shares. Because
of these class-specific expenses, the performance of a Portfolio's Premier
Shares is expected to be lower than the performance of the Portfolio's other
two share classes. Any person entitled to receive compensation for selling or
servicing shares of a Portfolio may receive different compensation with respect
to one particular class of shares over another in the same Portfolio. For
further information regarding the Trust's other share classes, contact Goldman
Sachs at 1-800-621-2550.     
   
The Trust's shareholders are entitled at the discretion of the Board of
Trustees to vote either on the basis of the number of shares held or the
aggregate net asset value represented by such shares. Each series entitled to
vote on a matter will vote thereon in the aggregate and not by series, except
as otherwise required by law or when the matter to be voted on affects only the
interests of shareholders of a particular series. The Additional Statement
gives examples of situations in which the law requires voting by series. Voting
rights are not cumulative and, accordingly, the holders of more than 50% of the
aggregate voting power of the Trust may elect all of the Trustees irrespective
of the vote of the other shareholders. In addition, holders of all shares
(regardless of class) representing interests in the same Portfolio have equal
voting rights except that only shares of a particular class within the
Portfolio will be entitled to vote on matters submitted to a vote of
shareholders (if any) relating to class-specific expenses that are payable by
that class of shares.     
   
As of February 28, 1998, Northern possessed sole or shared voting or investment
power for its customer accounts with respect to more than 50% of the
outstanding shares of the Trust.     
   
The Trust does not presently intend to hold annual meetings of shareholders
except as required by the 1940 Act or other applicable law. The Trustees will
promptly call a meeting of shareholders to vote upon the removal of any Trustee
when so requested in writing by the record holders of 10% or more of the
outstanding shares. To the extent required by law, the Trust will assist in
shareholder communications in connection with such a meeting.     
 
                                       26

The Trust Agreement provides that each shareholder, by virtue of becoming such,
will be held to have expressly assented and agreed to the terms of the Trust
Agreement and to have become a party thereto.
 
                                 MISCELLANEOUS
 
The address of the Trust is 4900 Sears Tower, Chicago, Illinois 60606 and the
telephone number is 1-800-621-2550.
   
When a shareholder moves, the shareholder is responsible for sending written
notice to the Trust of any new mailing address. The Trust and its transfer
agent may charge a shareholder their reasonable costs in locating a
shareholder's current address in accordance with SEC regulations.     
   
As used in this Prospectus, the term "Business Day" refers to each day when
Northern and the New York Stock Exchange are open, which is Monday through
Friday, except for holidays observed by Northern and/or the Exchange other than
Good Friday. For 1998, the holidays of Northern and/or the Exchange are: New
Year's Day, Dr. Martin Luther King, Jr. Day, Presidents' Day, Memorial Day,
Independence Day, Labor Day, Columbus Day, Veteran's Day, Thanksgiving and
Christmas Day. On those days when Northern or the Exchange closes early as a
result of unusual weather or other circumstances, the Portfolios reserve the
right to advance the time on that day by which purchase, redemption and
exchange requests must be received. In addition, on any Business Day when The
Bond Market Association recommends that the securities markets close or close
early, the Portfolios reserve the right to cease or to advance the deadline for
accepting purchase, redemption and exchange orders for same Business Day
credit. Purchase, redemption and exchange requests received after the advanced
closing time will be effected on the next Business Day. Each Portfolio
reserves, however, the right to reject any purchase order and also to defer
crediting, sending or wiring redemption proceeds for up to seven days after
receiving a redemption order if, in its judgment, an earlier payment would
adversely affect such Portfolio. See "Investing--Purchase of Premier Shares"
and "Investing--Redemption of Premier Shares" above for more information.

                       ADDITIONAL INVESTMENT INFORMATION


Investment Objectives and Policies

The following supplements the investment objectives and policies of the
Government Select, Government, Diversified Assets and Tax-Exempt Portfolios (the
"Portfolios") of The Benchmark Funds (the "Trust") as set forth in the
Prospectus.

Description of Commercial Paper, Bankers' Acceptances, Certificates of Deposit
and Time Deposits

Commercial paper represents short-term unsecured promissory notes issued in
bearer form by banks or bank holding companies, corporations and finance
companies.  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 that
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.

As stated in the Prospectus, the Diversified Assets Portfolio may invest a
portion of its assets in the obligations of foreign banks and foreign branches
of domestic banks.  Such obligations include Eurodollar Certificates of Deposit
("ECDs") which are U.S. dollar-denominated certificates of deposit issued by
offices of foreign and domestic banks located outside the United States;
Eurodollar Time Deposits ("ETDs") which are U.S. dollar-denominated deposits in
a foreign branch of a U.S. bank or a foreign bank; Canadian Time Deposits
("CTDs") which are essentially the same as ETDs except they are issued by
Canadian offices of major Canadian banks; Schedule Bs, which are obligations
issued by Canadian branches of foreign or domestic banks; Yankee Certificates of
Deposit ("Yankee CDs") which are U.S. dollar-denominated certificates of deposit
issued by a U.S. branch of a foreign bank and held in the United States; and
Yankee Bankers' Acceptances ("Yankee BAs") which are U.S. dollar-denominated
bankers' acceptances issued by a U.S. branch of a foreign bank and held in the
United States.

<PAGE>
 
Description of Asset-Backed Securities

   
The Diversified Assets Portfolio may purchase asset-backed securities, which are
securities backed by mortgages, installment contracts, credit card receivables
or other assets.  The average life of asset-backed securities varies with the
maturities of the underlying instruments, and the average life of a mortgage-
backed instrument, in particular, is likely to be substantially less than the
original maturity of the mortgage pools underlying the securities as a result of
mortgage prepayments.  For this and other reasons, an asset-backed security's
stated maturity may be shortened, and the security's total return may be
difficult to predict precisely.  Such difficulties are not, however, expected to
have a significant effect on the Portfolio since the remaining maturity of any
asset-backed security acquired, as calculated under applicable SEC regulations,
will be 13 months or less.  Asset-backed securities acquired by the Portfolio
may include collateralized mortgage obligations ("CMOs") issued by private
companies.
    
 
U.S. Government Obligations

Examples of the types of U.S. Government obligations that may be acquired by the
Portfolios include U.S. Treasury Bills, Treasury Notes and Treasury Bonds and
the obligations of Federal Home Loan Banks, Federal Farm Credit Banks, Federal
Land Banks, the Federal Housing Administration, Farmers Home Administration,
Export-Import Bank of the United States, Small Business Administration, Federal
National Mortgage Association, Government National Mortgage Association, General
Services Administration, Central Bank for Cooperatives, Federal Home Loan
Mortgage Corporation, Federal Intermediate Credit Banks, and the Maritime
Administration.

Custodial Receipts for Treasury Securities

The Portfolios (other than the Government Select Portfolio) may acquire U.S.
Government obligations and their unmatured interest coupons that have been
separated ("stripped") by their holder, typically a custodian bank or investment
brokerage firm.  Having separated the interest coupons from the underlying
principal of the U.S.  Government obligations, the holder will resell the
stripped securities in custodial receipt programs with a number of different
names, including "Treasury Income Growth Receipts" ("TIGRs") and "Certificate of
Accrual on Treasury Securities" ("CATS").  The stripped coupons are sold
separately from the underlying principal, which is usually sold at a deep
discount because the buyer receives only the right to receive a future fixed
payment on the security and does not receive any rights to periodic interest
(cash) payments.  The underlying U.S. Treasury bonds and notes themselves are
held in book-entry form at the Federal Reserve Bank or, in the case of bearer
securities (i.e., unregistered securities which are ostensibly owned by the
bearer or holder), in trust on behalf of

                                      -4-
<PAGE>
 
the owners.  Counsel to the underwriters of these certificates or other
evidences of ownership of U.S. Treasury securities have stated that, in their
opinion, purchasers of the stripped securities most likely will be deemed the
beneficial holders of the underlying U.S.  Government obligations for Federal
tax purposes.  The Trust is not aware of any binding legislative, judicial or
administrative authority on this issue.

U.S. Treasury STRIPS

The Treasury Department has facilitated transfers of ownership of zero coupon
securities by accounting separately for the beneficial ownership of particular
interest coupon and principal payments on Treasury securities through the
Federal Reserve book-entry record-keeping system. The Federal Reserve program as
established by the Treasury Department is known as "STRIPS" or "Separate Trading
of Registered Interest and Principal of Securities." Under the STRIPS program, a
Portfolio will be able to have its beneficial ownership of zero coupon
securities recorded directly in the book-entry record-keeping system in lieu of
having to hold certificates or other evidences of ownership of the underlying
U.S. Treasury securities.  All Portfolios, including the Government Select
Portfolio, may acquire securities registered under the STRIPS program.

Bank and Deposit Notes

The Diversified Assets Portfolio may purchase bank and deposit notes.  Bank
notes rank junior to deposit liabilities of banks and pari passu with other
                                                      ---- -----           
senior, unsecured obligations of the bank. Bank notes are classified as "other
borrowings" on a bank's balance sheet, while deposit notes and certificates of
deposit are classified as deposits. 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.

Variable and Floating Rate Instruments

With respect to the variable and floating rate instruments that may be acquired
by the Portfolios as described in the Prospectus, Northern will consider the
earning power, cash flows and other liquidity ratios of the issuers and
guarantors of such instruments and, if the instruments are subject to demand
features, will monitor their financial status and ability to meet payment on
demand.  Where necessary to ensure that a variable or floating rate instrument
is of "high quality," the issuer's obligation to pay the principal of the
instrument will be backed by an unconditional bank letter or line of credit,
guarantee or commitment to lend.  The Portfolios will invest in variable and
floating rate instruments only when Northern deems the investment to involve
minimal credit risk.  In determining weighted average portfolio maturity, an

                                      -5-
<PAGE>
 
instrument may, subject to SEC regulations, be deemed to have a maturity shorter
than its nominal maturity based on the period remaining until the next interest
rate adjustment or the time the Portfolio involved can recover payment of
principal as specified in the instrument.

Investment Companies

   
With respect to the investments of the Portfolios in the securities of other
investment companies, such investments will be limited so that, as determined
after a purchase is made, either (a) not more than 3% of the total outstanding
stock of such investment company will be owned by a Portfolio, the Trust as a
whole and their affiliated persons (as defined in the 1940 Act); or (b)(i) not
more than 5% of the value of the total assets of a Portfolio will be invested in
the securities of any one investment company, (ii) not more than 10% of the
value of its total assets will be invested in the aggregate in securities of
investment companies as a group, and (iii) not more than 3% of the outstanding
voting stock of any one investment company will be owned by the Portfolio.
    
 
   
Unaffiliated money market funds whose securities are purchased by the Portfolios
may not be obligated to redeem such securities in an amount exceeding 1% of
their total outstanding securities during any period of less than 30 days.
Therefore, such securities that exceed this amount may be illiquid.
    
 
   
If required by the 1940 Act, each Portfolio expects to vote the shares of other
investment companies that are held by it in the same proportion as the vote of
all other holders of such securities.
    
 
A Portfolio may invest all or substantially all of its assets in a single open-
end investment company or series thereof with substantially the same investment
objective, policies and restrictions as the Portfolio.  However, each Portfolio
currently intends to limit its investments in securities issued by other
investment companies to the extent described above.  A Portfolio may adhere to
more restrictive limitations with respect to its investments in securities
issued by other investment companies if required by the SEC or deemed to be in
the best interests of the Trust.

Repurchase Agreements

Each Portfolio may enter into repurchase agreements with financial institutions,
such as banks and broker-dealers, as are deemed creditworthy by Northern under
guidelines approved by the Trust's Board of Trustees.  The repurchase price
under the repurchase agreements will generally equal the price paid by a
Portfolio plus interest negotiated on the basis of current short-term rates
(which may be more or less than the rate on the securities underlying the

                                      -6-
<PAGE>
 
repurchase agreement).  Securities subject to repurchase agreements will be held
by the Trust's custodian (or subcustodian), in the Federal Reserve/Treasury
book-entry system or by another authorized securities depository.  Repurchase
agreements are considered to be loans by a Portfolio under the 1940 Act.

Reverse Repurchase Agreements

Each Portfolio (except the Tax-Exempt Portfolio) may borrow funds for temporary
or emergency purposes by selling portfolio securities to financial institutions
such as banks and broker/dealers and agreeing to repurchase them at a mutually
specified date and price ("reverse repurchase agreements"). Reverse repurchase
agreements involve the risk that the market value of the securities sold by a
Portfolio may decline below the repurchase price. The Portfolios will pay
interest on amounts obtained pursuant to a reverse repurchase agreement. While
reverse repurchase agreements are outstanding, a Portfolio will segregate liquid
assets in an amount at least equal to the market value of the securities, plus
accrued interest, subject to the agreement. Reverse repurchase agreements are
considered to be borrowings by a Portfolio under the 1940 Act.

Securities Lending

Collateral for loans of portfolio securities made by a Portfolio may consist of
cash, securities issued or guaranteed by the U.S. Government or its agencies or
irrevocable bank letters of credit (or any combination thereof).  The borrower
of securities will be required to maintain the market value of the collateral at
not less than the market value of the loaned securities, and such value will be
monitored on a daily basis.  When a Portfolio lends its securities, it continues
to receive interest on the securities loaned and may simultaneously earn
interest on the investment of the cash collateral which will be invested in
readily marketable, high-quality, short-term obligations. Although voting
rights, or rights to consent, attendant to securities on loan pass to the
borrower, such loans will be called so that the securities may be voted by a
Portfolio if a material event affecting the investment is to occur.

Forward Commitments and When-Issued Securities

Each Portfolio may purchase securities on a when-issued basis or purchase or
sell securities on a forward commitment (sometimes called delayed delivery)
basis.  These transactions involve a commitment by the Portfolio 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 normally negotiated directly with the other party.

                                      -7-
<PAGE>
 
   
  A Portfolio 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 Portfolio may
dispose of or negotiate a commitment after entering into it.  A Portfolio also
may sell securities it has committed to purchase before those securities are
delivered to the Portfolio on the settlement date.  The Portfolio may realize a
capital gain or loss in connection with these transactions.  For purposes of
determining a Portfolio's average dollar-weighted maturity, the maturity of
when-issued or forward commitment securities will be calculated from the
commitment date.  When a Portfolio purchases securities on a when-issued or
forward commitment basis, the Portfolio will segregate liquid assets having a
value (determined daily) at least equal to the amount of the Portfolio's
purchase commitments.  In the case of a forward commitment to sell portfolio
securities, the Portfolio will segregate the portfolio securities themselves.
These procedures are designed to ensure that the Portfolio will maintain
sufficient assets at all times to cover its obligations under when-issued
purchases and forward commitments.
    
 
Yields and Ratings

The yields on certain obligations, including the money market instruments in
which the Portfolios invest (such as commercial paper and bank obligations), are
dependent on a variety of factors, including general money market conditions,
conditions in the particular market for the obligation, financial condition of
the issuer, size of the offering, maturity of the obligation and ratings of the
issue.  The ratings of S&P, Moody's, D&P, Fitch and TBW represent their
respective opinions as to the quality of the obligations they undertake to rate.
Ratings, however, are general and are not absolute standards of quality.
Consequently, obligations with the same rating, maturity and interest rate may
have different market prices.

Municipal Instruments

Opinions relating to the validity of Municipal Instruments and to the exemption
of interest thereon from regular Federal income tax are rendered by bond counsel
to the respective issuing authorities at the time of issuance.  Neither the
Trust nor Northern will review the proceedings relating to the issuance of
Municipal Instruments or the bases for such opinions.

An issuer's obligations under its Municipal Instruments 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 Federal or state legislatures extending the time for
payment of principal or interest, or both, or imposing other constraints upon

                                      -8-
<PAGE>
 
enforcement of such obligations or upon the ability of municipalities to levy
taxes.  The power or ability of an issuer to meet its obligations for the
payment of interest on and principal of its Municipal Instruments may be
materially adversely affected by litigation or other conditions.

From time to time proposals have been introduced before Congress for the purpose
of restricting or eliminating the Federal income tax exemption for interest on
Municipal Instruments.  For example, under the Tax Reform Act of 1986 interest
on certain private activity bonds must be included in an investor's Federal
alternative minimum taxable income, and corporate investors must include all
tax-exempt interest in their Federal alternative minimum taxable income.  The
Trust cannot predict what legislation, if any, may be proposed in the future in
Congress as regards the Federal income tax status of interest on Municipal
Instruments. Future proposals could materially adversely affect the availability
of Municipal Instruments for investment by the Tax-Exempt Portfolio and the
liquidity and value of the Portfolio.  In such an event the Board of Trustees
would reevaluate the Portfolio's investment objective and policies and consider
changes in its structure or possible dissolution.

Interest earned by the Tax-Exempt Portfolio on private activity bonds (if any)
that is treated as a specific tax preference item under the Federal alternative
minimum tax will not be deemed to have been derived from Municipal Instruments
for purposes of determining whether that Portfolio meets its fundamental policy
that at least 80% of its annual gross income be derived from Municipal
Instruments.

Standby Commitments

The Tax-Exempt Portfolio may enter into standby commitments with respect to
Municipal Instruments held by it.  Under a standby commitment, a dealer agrees
to purchase at the Portfolio's option a specified Municipal Instrument at its
amortized cost value to the Portfolio plus accrued interest, if any.  Standby
commitments may be exercisable by the Portfolio at any time before the maturity
of the underlying Municipal Instruments and may be sold, transferred or assigned
only with the instruments involved.

The Tax-Exempt Portfolio expects that standby commitments will generally be
available without the payment of any direct or indirect consideration. However,
if necessary or advisable, the Portfolio may pay for a standby commitment either
separately in cash or by paying a higher price for Municipal Instruments which
are acquired subject to the commitment (thus reducing the yield to maturity
otherwise available for the same securities).  The total amount paid in either
manner for outstanding standby commitments held by the Portfolio will not exceed
1/2 of 1% of the value of the

                                      -9-
<PAGE>
 
Portfolio's total assets calculated immediately after each standby commitment is
acquired.

The Portfolio intends to enter into standby commitments only with dealers, banks
and broker-dealers which, in Northern's opinion, present minimal credit risks.
The Portfolio will acquire standby commitments solely to facilitate portfolio
liquidity and does not intend to exercise its rights thereunder for trading
purposes.  The acquisition of a standby commitment will not affect the valuation
or assumed maturity of the underlying Municipal Instrument.  The actual standby
commitment will be valued at zero in determining net asset value. Accordingly,
where the Portfolio pays directly or indirectly for a standby commitment, its
cost will be reflected as an unrealized loss for the period during which the
commitment is held by the Portfolio and will be reflected in realized gain or
loss when the commitment is exercised or expires.

Investment Restrictions

Each Portfolio is subject to the fundamental investment restrictions enumerated
below which may be changed with respect to a particular Portfolio only by a vote
of the holders of a majority of such Portfolio's outstanding shares.

No Portfolio may:

     (1) Make loans, except (a) through the purchase of debt obligations in
     accordance with the Portfolio's investment objective and policies, (b)
     through repurchase agreements with banks, brokers, dealers and other
     financial institutions, and (c) loans of securities.

     (2) Mortgage, pledge or hypothecate any assets (other than pursuant to
     reverse repurchase agreements for the Diversified Assets, Government and
     Government Select Portfolios) except to secure permitted borrowings.

     (3) Purchase or sell real estate or securities issued by real estate
     investment trusts, but this restriction shall not prevent a Portfolio from
     investing directly or indirectly in portfolio instruments secured by real
     estate or interests therein.

     (4) Purchase or sell commodities or commodity contracts or oil or gas or
     other mineral exploration or development programs.

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

     (6) Act as underwriter of securities (except as a Portfolio may be deemed
     to be an underwriter under the Securities Act of

                                      -10-

     1933 in connection with the purchase and sale of portfolio instruments in
     accordance with its investment objective and portfolio management
     policies), 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 or  maintain
     a short position, or write puts, calls or combinations thereof.

   
     (7) Make any investment inconsistent with the Portfolio's classification as
     a diversified investment company under the 1940 Act.
    
 
     (8) Purchase securities if such purchase would cause more than 25% in the
     aggregate of the market value of the total assets of a Portfolio 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 Portfolio 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 foreign banks and
     repurchase agreements and securities loans collateralized by such U.S.
     Government obligations 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; as to utility companies, the
     gas, electric, water and telephone businesses are considered separate
     industries; 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 industries of their parents if their
     activities are primarily related to financing the activities of their
     parents.

     (9) Borrow money (other than pursuant to reverse repurchase agreements for
     the Portfolios described above), except (a) as a temporary measure, and
     then only in amounts not exceeding 5% of the value of the Portfolio's total
     assets or (b) from banks, provided that immediately after any such
     borrowing all borrowings of the Portfolio do not exceed one-third of the
     Portfolio's total assets.  No purchases of securities will be made if
     borrowings subject to this restriction exceed 5% of the value of the
     Portfolio's assets. The exceptions in (a) and (b) to this restriction are
     not for investment leverage purposes but are solely for extraordinary or
     emergency purposes or to facilitate management of the Trust's Portfolios by
     enabling the Trust to meet redemption requests when the liquidation of
     portfolio instruments is deemed to be disadvantageous or not possible.  If
     due to market fluctuations or other reasons the total assets of a Portfolio

                                      -11-
<PAGE>
 
     fall below 300% of its borrowings, the Trust will promptly reduce the
     borrowings of such Portfolio in accordance with the 1940 Act.

     (10) Notwithstanding any of the Trust's other fundamental investment
     restrictions (including, without limitation, those restrictions relating to
     issuer diversification, industry concentration and control), each Portfolio
     may (a) purchase securities of other investment companies to the full
     extent permitted under Section 12 of the 1940 Act (or any successor
     provision thereto) or under any regulation or order of the Securities and
     Exchange Commission; and (b) invest all or substantially all of its assets
     in a single open-end investment company or series thereof with
     substantially the same investment objective, policies and fundamental
     restrictions as the Portfolio.


                                  *    *    *

   
The freedom of action reserved in Restriction No. 8 with respect to U.S.
branches of foreign banks is subject to the requirement that they are subject to
the same regulation as domestic branches of U.S. banks.  Obligations of U.S.
branches of foreign banks may include certificates of deposit, bank and deposit
notes, bankers' acceptances and fixed time deposits, and may be general
obligations of the parent bank or may be limited to the issuing branch.  Such
obligations will meet the criteria for "Eligible Securities" as described in the
Prospectus.
    
 
In addition, as matters of fundamental policy, the Government Select Portfolio,
Government Portfolio and Diversified Assets Portfolio may not enter into reverse
repurchase agreements exceeding in the aggregate one-third of the applicable
Portfolio's total assets; and the Tax-Exempt Portfolio may not acquire direct
ownership of industrial development bonds if, as a result of such acquisition,
more than 5% of the value of its total assets would be invested in industrial
development bonds where payment of principal and interest is the responsibility
of companies (including their predecessors) with less than three years of
operating history and such bonds are not guaranteed as to principal and interest
by companies (including their predecessors) with three years or more of
operating history.

   
Except to the extent otherwise provided in Investment Restriction No. 8, for the
purpose of such restriction in determining industry classification the Trust
intends to use the industry classification titles in the Standard Industrial
Classification Manual.
    
 
In applying Restriction No. 8 above, a security is considered to be issued by
the entity, or entities, whose assets and revenues back the security.  A
guarantee of a security is not deemed to be a

                                      -12-
<PAGE>
 
security issued by the guarantor when the value of all securities issued and
guaranteed by the guarantor, and owned by a Portfolio, does not exceed 10% of
the value of the Portfolio's total assets.

Any restriction which involves a maximum percentage will 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.

   
The Portfolios intend, as a non-fundamental policy, to diversify their
investments in accordance with current SEC regulations.  Investments in the
securities of any single issuer (excluding cash, cash items, certain repurchase
agreements, U.S. Government securities and securities of other investment
companies) will be limited to not more than 5% of the value of a Portfolio's
total assets at the time of purchase, except that 25% of the value of the total
assets of each Portfolio may be invested in the securities of any one issuer for
a period of up to three Business Days.  A security that has an unconditional
guarantee meeting special SEC requirements (a "Guarantee") does not need to
satisfy the foregoing issuer diversification requirements that would otherwise
apply, but the Guarantee is instead subject to the following diversification
requirements:  Immediately after the acquisition of the security, a Portfolio
may not have invested more than 10% of its total assets in securities issued by
or subject to Guarantees from the same person, except that a Fund may, subject
to certain conditions, invest up to 25% of its total assets in securities issued
or subject to Guarantees of the same person.  This percentage is 100% if the
Guarantee is issued by the U.S. Government or an agency thereof.  In addition,
the Tax-Exempt Portfolio will limit its investments in certain conduit
securities that are not rated in the highest short-term rating category as
determined by two NRSROs (or one NRSRO if the security is rated by only one
NRSRO) or, if unrated, are not of comparable quality ("Second Tier Securities"),
to 5% of its total assets, with investments in any one such issuer being limited
to no more than 1% of the Portfolio's total assets or $1 million, whichever is
greater, measured at the time of purchase.  Conduit securities subject to this
limitation are Municipal Instruments that are not subject to a Guarantee and
involve an arrangement whereunder a person, other than a municipal issuer,
provides for or secures repayment of the security and are not:  (i) fully and
unconditionally guaranteed by a municipal issuer; or (ii) payable from the
general revenues of the municipal issuer or other municipal issuers; or (iii)
related to a project owned and operated by a municipal issuer; or (iv) related
to a facility leased to and under the control of an industrial or commercial
enterprise that is part of a public project which, as a whole, is owned and
under the control of a municipal issuer.  The Diversified Assets Portfolios will
limit its investments in all Second Tier Securities (that are not subject to a
Guarantee) in accordance with the foregoing percentage limitations.
    
 

                                      -13-
<PAGE>
 
   
     In addition to the foregoing, each Portfolio is subject to additional
diversification requirements imposed by SEC regulations on the acquisition of
securities subject to other types of demand features and puts whereunder a
Portfolio has the right to sell the securities to third parties.

Certain of the Trustees and officers and the organizations with which they are
associated have had in the past, and may have in the future, transactions with
Northern, Goldman Sachs and their respective affiliates.  The Trust has been
advised by such Trustees and officers that all such transactions have been and
are expected to be in the ordinary course of business and the terms of such
transactions, including all loans and loan commitments by such persons, have
been and are expected to be substantially the same as the prevailing terms for
comparable transactions for other customers.  Messrs.  Springer, Kelsey,
Strubel, Mosior, Gilman, Richman, Surloff and Hartstein and Mmes.  Farrell,
Mucker and Zondorak hold similar positions with one or more investment companies
that are advised by Goldman Sachs.  As a result of the responsibilities assumed
by Northern under its Advisory Agreement, Transfer Agency Agreement and
Custodian Agreement and Foreign Custody Agreement with the Trust and by Goldman
Sachs under its Administration Agreement and Distribution Agreement with the
Trust, the Trust itself requires no employees.

Each officer holds comparable positions with certain other investment companies
of which Goldman Sachs, GSAM or an affiliate thereof is the investment adviser,
administrator and/or distributor.

Each Trustee earns a quarterly retainer of $6,250 and the Chairman of the Board
earns a quarterly retainer of $9,375.  Each Trustee, including the Chairman of
the Board, earns an additional fee of $1,500 for each meeting attended, plus
reimbursement of expenses incurred as a Trustee.

In addition, the Trustees established an Audit Committee consisting of three
members including a Chairman of the Committee.  Each member earns a fee of
$1,500 for each meeting attended and the Chairman earns a quarterly retainer of
$1,250.

Each Trustee will hold office for an indefinite term until the earliest of (1)
the next meeting of shareholders, if any, called for the purpose of considering
the election or re-election of such Trustee and until the election and
qualification of his or her successor, if any, elected at such meeting; (2) the
date a Trustee resigns or retires, or a Trustee is removed by the Board of
Trustees or shareholders, in accordance with the Trust's Agreement and
Declaration of Trust, or (3) in accordance with the current

                                      -18-
<PAGE>
 
resolutions of the Board of Trustees (which may be changed without shareholder
vote), on the last day of the fiscal year of the Trust in which he or she
attains the age of 72 years.

The Trust's officers do not receive fees from the Trust for services in such
capacities, although Goldman Sachs, of which they are also officers, receives
fees from the Trust for administrative services.

Investment Adviser, Transfer Agent and Custodian

Northern, a wholly-owned subsidiary of Northern Trust Corporation, a bank
holding company, is one of the nation's leading providers of trust and
investment management services.  As of December 31, 1997, Northern and its
affiliates had over $196 billion in assets under management for clients
including public and private retirement funds, endowments, foundations, trusts,
corporations, and individuals.  Northern is one of the strongest banking
organizations in the United States.  Northern believes it has built its
organization by serving clients with integrity, a commitment to quality, and
personal attention.  Its stated mission with respect to all its financial
products and services is to achieve unrivaled client satisfaction.  With respect
to such clients, the Trust is designed to assist (i) defined contribution plan
sponsors and their employees by offering a range of diverse investment options
to help comply with 404(c) regulation and may also provide educational material
to their employees, (ii) employers who provide post-retirement Employees'
Beneficiary Associations ("VEBA") and require investments that respond to the
impact of federal regulations, (iii) insurance companies with the day-to-day
management of uninvested cash balances as well as with longer-term investment
needs, and (iv) charitable and not-for-profit organizations, such as endowments
and foundations, demanding investment management solutions that balance the
requirement for sufficient current income to meet operating expenses and the
need for capital appreciation to meet future investment objectives.

Under its Advisory Agreement with the Trust, Northern, subject to the general
supervision of the Trust's Board of Trustees, is responsible for making
investment decisions for each Portfolio and placing purchase and sale orders for
the portfolio transactions of the Portfolios. In connection with portfolio
transactions for the Portfolios, which are generally done at a net price without
a broker's commission, Northern's Advisory Agreement provides that Northern
shall attempt to obtain the best net price and execution. To the extent the
execution and price available from more than one broker, dealer or other such
persons are believed to be comparable, Northern may, at its discretion but
subject to applicable law, select the executing broker, dealer or such other
persons on the basis of Northern's opinion of the reliability and quality of
such broker, dealer or such other persons.

For the fiscal years ended November 30, 1997, 1996 and 1995, all portfolio
transactions for the Portfolios were executed on a principal basis and,
therefore, no brokerage commissions were paid by the Portfolios.  Purchases by
the Portfolios from underwriters of portfolio securities, however, normally
include a commission or concession paid by the issuer to the underwriter, and
purchases from dealers include the spread between the dealer's cost for a given
security and the resale price of the security.

                                      -21-

Northern's investment advisory duties for the Trust are carried out through its
Trust Department.  On occasions when Northern deems the purchase or sale of a
security to be in the best interests of a Portfolio as well as other fiduciary
or agency accounts managed by it (including any other Portfolio, investment
company or account for which Northern acts as adviser), the Agreement provides
that Northern, to the extent permitted by applicable laws and regulations, may
aggregate the securities to be sold or purchased for such Portfolio with those
to be sold or purchased for such other accounts in order to obtain best net
price and execution.  In such event, allocation of the securities so purchased
or sold, as well as the expenses incurred in the transaction, will be made by
Northern in the manner it considers to be most equitable and consistent with its
fiduciary obligations to the Portfolio and other accounts involved.  In some
instances, this procedure may adversely affect the size of the position
obtainable for a Portfolio or the amount of the securities that are able to be
sold for a Portfolio.  To the extent that the execution and price available from
more than one broker or dealer are believed to be comparable, the Agreement
permits Northern, at its discretion but subject to applicable law, to select the
executing broker or dealer on the basis of Northern's opinion of the reliability
and quality of such broker or dealer.

The Advisory Agreement provides that Northern may render similar services to
others so long as its services under such Agreement are not impaired thereby.
The Advisory Agreement also provides that the Trust will indemnify Northern
against certain liabilities (including liabilities under the Federal securities
laws relating to untrue statements or omissions of material fact and actions
that are in accordance with the terms of the Agreement) or, in lieu thereof,
contribute to resulting losses.

Under its Transfer Agency Agreement with the Trust, Northern has undertaken to
(1) answer customer inquiries regarding the current yield of, and certain other
matters (e.g. account status information) pertaining to, the Trust, (2) process
purchase and redemption transactions, including transactions generated by any
service provided outside of the Agreement by Northern, its affiliates or
correspondent banks whereby customer account cash balances are automatically
invested in shares of the Portfolios, and the disbursement of the proceeds of
redemptions, (3) establish and maintain separate omnibus accounts with respect
to shareholders investing through Northern or any of its affiliates and
correspondent banks and act as transfer agent and perform sub-accounting
services with respect to each such account, (4) provide periodic statements
showing account balances, (5) mail reports and proxy materials to shareholders,
(6) provide information in connection with the preparation by the Trust of
various regulatory reports and prepare reports to the Trustees and management,
(7) answer inquiries (including requests for prospectuses and statements of
additional information, and

                                      -22-
<PAGE>
 
assistance in the completion of new account applications) from investors and
respond to all requests for information regarding the Trust (such as current
price, recent performance, and yield data) and questions relating to accounts of
investors (such as possible errors in statements, and transactions), (8) respond
to and seek to resolve all complaints of investors with respect to the Trust or
their accounts, (9) furnish proxy statements and proxies, annual and semi-annual
financial statements, and dividend, distribution and tax notices to investors,
(10) furnish the Trust all pertinent Blue Sky information, (11) perform all
required tax withholding, (12) preserve records, and (13) furnish necessary
office space, facilities and personnel. Northern may appoint one or more sub-
transfer agents in the performance of its services.

As compensation for the services rendered by Northern under the Transfer Agency
Agreement with respect to Service Shares and Premium Shares and the assumption
by Northern of related expenses, Northern is entitled to a fee from the Trust,
calculated daily and payable monthly, at the following annual rates:  (i) .01%
of the average daily net asset value of the outstanding Service Shares of each
Portfolio; and (ii) .02% of the average daily net asset value of the outstanding
Premier Shares of each Portfolio.  The transfer agency fee attributable to each
class of shares is borne solely by that class.  Northern's affiliates and
correspondent banks may receive compensation for performing the services
described in the preceding paragraph that Northern would otherwise receive.
Conflict-of-interest restrictions under state and Federal law (including the
Employee Retirement Income Security Act of 1974) may apply to the receipt by
such affiliates or correspondent banks of such compensation in connection with
the investment of fiduciary funds in Service Shares and Premium Shares.

Under its Custodian Agreement with the Trust, Northern (1) holds each
Portfolio's cash and securities, (2) maintains such cash and securities in
separate accounts in the name of the Portfolio, (3) makes receipts and
disbursements of funds on behalf of the Portfolio, (4) receives, delivers and
releases securities on behalf of the Portfolio, (5) collects and receives all
income, principal and other payments in respect of the Portfolio's securities
held by Northern under the Agreement, and (6) maintains the accounting records
of the Trust.  Northern may, subject to certain monitoring responsibilities,
employ one or more subcustodians, provided that Northern shall have no more
responsibility or liability to the Trust on account of any action or omission of
any subcustodian so employed than such subcustodian has to Northern and that the
responsibility or liability of the subcustodian to Northern shall conform to the
resolution of the Trustees of the Trust authorizing the appointment of the
particular subcustodian. Northern may also appoint agents to carry out such of
the provisions of the Custodian Agreement as Northern may from time to time
direct, provided that the appointment of an agent shall not relieve Northern of
any of its responsibilities under the Agreement.

                                      -23-

As compensation for the services rendered to the Trust by Northern as
custodian, and the assumption by Northern of certain related expenses, Northern
is entitled to payment from the Trust as follows: (i) $18,000 annually for each
Portfolio, plus (ii) 1/100th of 1% annually of each Portfolio's average daily
net assets to the extent they exceed $100 million, plus (iii) a fixed dollar fee
for each trade in portfolio securities, plus (iv) a fixed dollar fee for each
time that Northern as custodian receives or transmits funds via wire, plus (v)
reimbursement of expenses incurred by Northern as custodian for telephone,
postage, courier fees, office supplies and duplicating.  The fees referred to in
clauses (iii) and (iv) are subject to annual upward adjustments based on
increases in the Consumer Price Index for All Urban Consumers, provided that
Northern may permanently or temporarily waive all or any portion of any upward
adjustment.

Northern's fees under the Custodian Agreement are subject to reduction based on
the Portfolios' daily uninvested cash balances (if any).

Unless sooner terminated, each of the Advisory Agreement, Transfer Agency
Agreement and Custodian Agreement between Northern and the Trust will continue
in effect with respect to a particular Portfolio until April 30, 1999, and
thereafter for successive 12-month periods, provided that the continuance is
approved at least annually (1) by the vote of a majority of the Trustees who are
not parties to the agreement or "interested persons" (as such term is defined in
the 1940 Act) of any party thereto, cast in person at a meeting called for the
purpose of voting on such approval and (2) by the Trustees or by the vote of a
majority of the outstanding shares of such Portfolio (as defined below under
"Other Information").  Each agreement is terminable at any time without penalty
by the Trust (by specified Trustee or shareholder action) on 60 days' written
notice to Northern and by Northern on 60 days' written notice to the Trust.

For the fiscal periods ended November 30 as indicated, the amount of the

Banking laws and regulations currently prohibit a bank holding company
registered under the Federal Bank Holding Company Act of 1956 or any bank or
non-bank affiliate thereof from sponsoring, organizing, controlling or
distributing the shares of a registered open-end investment company continuously
engaged in the issuance of its shares, but such banking laws and regulations do
not prohibit such a holding company or affiliate or banks generally from acting
as investment adviser, transfer agent or custodian to such an investment
company, or from purchasing shares of such a company as agent for and upon the
order of customers.  Northern believes that it may perform the services
contemplated by its agreements with the Trust without violation of such banking
laws or regulations, which are applicable to it. It should be noted, however,
that future changes in either Federal or state statutes and regulations relating
to the permissible activities of banks and their subsidiaries or affiliates, as
well as future judicial or administrative decisions or interpretations of
current and future statutes and regulations, could prevent Northern from
continuing to perform such services for the Trust.

Should future legislative, judicial or administrative action prohibit or
restrict the activities of Northern in connection with the provision of services
on behalf of the Trust, the Trust might be required to alter materially or
discontinue its arrangements with Northern and change its method of operations.
It is not anticipated, however, that any change in the Trust's method of
operations would affect the net asset value per share of any Portfolio or result
in a financial loss to any shareholder.  Moreover, if current restrictions
preventing a bank from legally sponsoring, organizing, controlling or
distributing shares of an open-end investment company were relaxed, the Trust
expects that Northern and its affiliates would consider the possibility of
offering to perform some or all of the services now provided by

                                      -25-
<PAGE>
 
Goldman Sachs.  It is not possible, of course, to predict whether or in what
form such restrictions might be relaxed or the terms upon which Northern and its
affiliates might offer to provide services for consideration by the Trustees.

Northern is active as an underwriter of municipal instruments. Under the 1940
Act, the Portfolios are precluded, subject to certain exceptions, from
purchasing in the primary market those municipal instruments with respect to
which Northern is serving as a principal underwriter.  In the opinion of
Northern, this limitation will not significantly affect the ability of the
Portfolios to pursue their respective investment objectives. Goldman Sachs is
also an active investor, dealer and/or underwriter in many types of money market
instruments.  Its activities in this regard could have some effect on the market
for those instruments which the Portfolios acquire, hold or sell.

In the Advisory Agreement, Northern agrees that the name "The Benchmark" may be
used in connection with the Trust's business on a royalty-free basis.  Northern
has reserved to itself the right to grant the non-exclusive right to use the
name "The Benchmark" to any other person.  The Advisory Agreement provides that
at such time as the Agreement is no longer in effect, the Trust will cease using
the name "The Benchmark." (This undertaking by the Trust may be subject to
certain legal limitations.)

Administrator and Distributor

Under its Administration Agreement with the Trust, Goldman Sachs, subject to the
general supervision of the Trust's Board of Trustees, acts as the Trust's
Administrator.  In this capacity, Goldman Sachs (1) provides supervision of all
aspects of the Trust's non-investment advisory operations (the parties giving
due recognition to the fact that certain of such operations are performed by
Northern pursuant to the Trust's agreements with Northern), (2) provides the
Trust, to the extent not provided pursuant to such agreements, with such
personnel as are reasonably necessary for the conduct of the Trust's affairs,
(3) arranges, to the extent not provided pursuant to such agreements, for the
preparation at the Trust's expense of its tax returns, reports to shareholders,
periodic updating of the Prospectus issued by the Trust, and reports filed with
the SEC and other regulatory authorities (including qualification under state
securities or Blue Sky laws of the Trust's shares), and (4) provides the Trust,
to the extent not provided pursuant to such agreements, with adequate office
space and equipment and certain related services in Chicago.

For the fiscal periods ended November 30 as indicated, Goldman Sachs received
fees under the Administration Agreement (after fee waivers) in the amount of:
 
                                   1997        1996        1995
                                ----------  ----------  ----------
 
Government Select Portfolio     $1,048,482  $  897,049  $  751,804
Government Portfolio             1,208,401   1,036,172     895,112
Diversified Assets Portfolio     3,082,370   2,079,083   1,928,672
Tax-Exempt Portfolio               749,232     885,446     828,163
 
In addition, pursuant to an undertaking that commenced August 1, 1992, Goldman
Sachs agreed that, if its administration fees (less expense reimbursements paid
by Goldman Sachs to the Trust and less certain marketing expenses paid by
Goldman Sachs) exceed a specified amount ($1 million for the Trust's first
twelve investment portfolios plus $50,000 for each additional portfolio) during
the current fiscal year, Goldman Sachs will waive a portion of its
administration fees during the following fiscal year.  This undertaking may be
terminated by Goldman Sachs at any time without the consent of the Trust or the
shareholders. There have been no waivers pursuant to this agreement during the
last three fiscal periods.

Goldman Sachs has agreed for the current fiscal year to reimburse each Portfolio
for the sum of the Portfolios' expenses (including fees payable to Goldman Sachs
as administrator, but excluding the fees payable to Northern for its duties as
investment adviser and transfer agent, payments under the service plan for the
Portfolios'

                                      -27-
<PAGE>
 
Service and Premier Share classes, and extraordinary expenses) which exceed on
an annualized basis .10% of each Portfolio's average daily net assets.  Prior to
May 1, 1997, this undertaking was voluntary with respect to the Portfolios.  As
of May 1, 1997, this undertaking is contractual with respect to all Portfolios.

For the fiscal periods ended November 30 as indicated, and prior to May 1, 1997,
Goldman Sachs voluntarily agreed to waive a portion of its Administration Fee
for each Portfolio resulting in an effective fee of .10% of the average daily
net assets for each Portfolio. The effect of these waivers by Goldman Sachs was
to other expense by the following amounts:
 
                                  1997      1996      1995

Tax-Exempt Portfolio             305,530   382,218   389,481
 
Effective April 1, 1998, (upon the offering of the Service and Premier Shares),
Goldman Sachs will reimburse "other expenses" of each Portfolio (including fees
payable to Goldman Sachs as administrator, but excluding the fees payable to
Northern for its duties as adviser and transfer agent, payments under the
service plan for Service and Premier Shares, and certain extraordinary expenses)
exceeds on an annualized basis .10% of each Portfolio's average daily net
assets.

Unless sooner terminated, the Administration Agreement will continue in effect
with respect to a particular Portfolio until April 30, 1999, and thereafter for
successive 12-month periods, provided that the agreement is approved annually
(1) by the vote of a majority of the Trustees who are not parties to the
agreement or "interested persons" (as such term is defined by the 1940 Act) of
any party thereto, cast in person at a meeting called for the purpose of voting
on such approval, and (2) by the Trustees or by the vote of a majority of the
outstanding shares of such Portfolio (as defined below under "Other
Information").  The Administration Agreement is terminable at any time without
penalty by the Trust (upon specified Trustee or shareholder action) on 60 days'
written notice to Goldman Sachs and by Goldman Sachs on 60 days' written notice
to the Trust.

The Trust has entered into a Distribution Agreement under which Goldman Sachs,
as agent, sells shares of each Portfolio on a continuous basis.  Goldman Sachs
pays the cost of printing and distributing prospectuses to persons who are not
shareholders of Trust shares (excluding preparation and typesetting expenses)
and of all other sales presentations, mailings, advertising and other
distribution efforts.  No compensation is payable by the Trust to Goldman Sachs
for such distribution services.

                                      -28-
<PAGE>
 
The Administration Agreement and the Distribution Agreement provide that
Goldman Sachs may render similar services to others so long as its services
under such Agreements are not impaired thereby.  The Administration Agreement
provides that the Trust will indemnify Goldman Sachs against certain liabilities
(including liabilities under the Federal securities laws relating to untrue
statements or omissions of material fact and actions that are in accordance with
the terms of the Administration Agreement and Distribution Agreement) or, in
lieu thereof, contribute to resulting losses.

Counsel and Auditors

Drinker Biddle & Reath LLP, with offices at 1345 Chestnut Street, Suite 1100,
Philadelphia, Pennsylvania 19107, serve as counsel to the Trust.

Ernst & Young LLP, independent auditors, 233 S. Wacker Drive, Chicago, Illinois
60606, have been selected as auditors of the Trust.  In addition to audit
services, Ernst & Young LLP reviews the Trust's Federal and state tax returns,
and provides consultation and assistance on accounting, internal control and
related matters.

In-Kind Purchases

Payment for shares of a Portfolio may, at the discretion of Northern, be made in
the form of securities that are permissible investments for the Portfolio as
described in the Prospectus. For further information about this form of payment,
contact Northern. In connection with an in-kind securities payment, a Portfolio
will require, among other things, that the securities be valued on the day of
purchase in accordance with the pricing methods used by the Portfolio and that
the Portfolio receive satisfactory assurances that it will have good and
marketable title to the securities received by it; that the securities be in
proper form for transfer to the Portfolio; and that adequate information be
provided concerning the basis and other tax matters relating to the securities.


                            PERFORMANCE INFORMATION

From time to time, the Trust may advertise quotations of "yields" and "effective
yields" with respect to each Portfolio's Service Shares and Premier Shares, and
"tax-equivalent yields" with respect to Service Shares and Premier Shares of the
Government Select Portfolio and Tax-Exempt Portfolio computed in accordance with
a standardized method, based upon the seven-day period ended on the date of
calculation.  Yield, effective yield and tax equivalent yield are computed
separately for each class of shares.  Each class of shares has different fees
and expenses, and consequently, may have different yields for the same period.
In arriving at such quotations as to "yield," the Trust first determines the net
change

                                      -29-
<PAGE>
 
during the period in the value of a hypothetical pre-existing account having a
balance of one Service Share or Premier Share at the beginning of the period
(such net change being inclusive of the value of any additional shares of the
same class issued in connection with distributions of net investment income as
well as net investment income accrued on both the original share and any such
additional shares, but exclusive of realized gains and losses from the sale of
securities and unrealized appreciation and depreciation), then divides such net
change by the value of the account at the beginning of the period to obtain the
base period return, and then multiplies the base period return by 365/7.

The "effective yield" with respect to the Service Shares and Premier Shares of a
Portfolio is computed by adding 1 to the base period return (calculated as
above), raising the sum to a power equal to 365 divided by 7, and subtracting 1
from the result.

"Tax-equivalent yield" is computed by dividing the tax-exempt portion of the
yield by 1 minus a stated income tax rate, and then adding the product to the
taxable portion of the yield, if any.  There may be more than one tax-equivalent
yield, if more than one stated income tax rate is used.

Quotations of yield, effective yield and tax-equivalent yield provided by the
Trust are carried to at least the nearest hundredth of one percent.  Any fees
imposed by Northern, its affiliates or correspondent banks on their customers in
connection with investments in shares of the Portfolios are not reflected in the
calculation of yields for the Portfolios.

Each Portfolio's yields fluctuate, unlike bank deposits or other investments
which pay a fixed yield for a stated period of time. The annualization of one
week's income is not necessarily indicative of future actual yields.  Actual
yields will depend on such variables as portfolio quality, average portfolio
maturity, the type of portfolio instruments acquired, changes in money market
interest rates, portfolio expenses and other factors.  Yields are one basis
investors may use to analyze a class of shares of the Portfolio as compared to
comparable classes of shares of other money market funds and other investment
vehicles.  However, yields of comparable classes of shares of other money market
funds and other investment vehicles may not be comparable because of the
foregoing variables, and differences in the methods used in valuing their
portfolio instruments, computing net asset value and determining yield.

Each Portfolio may also quote from time to time the total return of its Service
Shares or Premier Shares in accordance with SEC regulations.

                                      -30-
<PAGE>
 
   
The yields and total returns of each class of shares of a Portfolio will be
calculated separately from the yields and total returns of the other share
classes.
    
 

                            AMORTIZED COST VALUATION

As stated in the Prospectus, each Portfolio seeks to maintain a net asset value
of $1.00 per share and, in this connection, values its instruments on the basis
of amortized cost pursuant to Rule 2a-7 under the 1940 Act.  This method values
a security at its cost on the date of purchase and thereafter assumes a constant
amortization to maturity of any discount or premium, regardless of the impact of
fluctuating interest rates on the market value of the instrument.  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
Portfolio would receive if the Portfolio sold the instrument.  During such
periods the yield to investors in the Portfolio may differ somewhat from that
obtained in a similar entity which uses available indications as to market value
to value its portfolio instruments.  For example, if the use of amortized cost
resulted in a lower (higher) aggregate Portfolio value on a particular day, a
prospective investor in the Portfolio would be able to obtain a somewhat higher
(lower) yield and ownership interest than would result from investment in such
similar entity and existing investors would receive less (more) investment
income and ownership interest.  However, the Trust expects that the procedures
and limitations referred to in the following paragraphs of this section will
tend to minimize the differences referred to above.

Under Rule 2a-7, the Trust's Board of Trustees, in supervising the Trust's
operations and delegating special responsibilities involving portfolio
management to Northern, has established procedures that are intended, taking
into account current market conditions and the Portfolios' investment
objectives, to stabilize the net asset value of each Portfolio, as computed for
the purposes of purchases and redemptions, at $1.00 per share.  The Trustees'
procedures include periodic monitoring of the difference (the "Market Value
Difference") between the amortized cost value per share and the net asset value
per share based upon available indications of market value.  Available
indications of market value used by the Trust consist of actual market
quotations or appropriate substitutes which reflect current market conditions
and include (a) quotations or estimates of market value for individual portfolio
instruments and/or (b) values for individual portfolio instruments derived from
market quotations relating to varying maturities of a class of money market
instruments.  In the event the Market Value Difference of a given Portfolio
exceeds certain limits or Northern believes that the Market Value Difference may
result in material dilution or other unfair results to investors or existing
shareholders, the Trust will take action in accordance

                                      -31-
<PAGE>
 
with the 1940 Act and the Trustees will take such steps as they consider
appropriate (e.g., selling portfolio instruments to shorten average portfolio
maturity or to realize capital gains or losses, reducing or suspending
shareholder income accruals, redeeming shares in kind, or utilizing a net asset
value per share based upon available indications of market value which under
such circumstances would vary from $1.00) to eliminate or reduce to the extent
reasonably practicable any material dilution or other unfair results to
investors or existing shareholders which might arise from Market Value
Differences.  In particular, if losses were sustained by a Portfolio, the number
of outstanding shares might be reduced in order to maintain a net asset value
per share of $1.00.  Such reduction would be effected by having each shareholder
proportionately contribute to the Portfolio's capital the necessary shares to
restore such net asset value per share.  Each shareholder will be deemed to have
agreed to such contribution in these circumstances by investing in the
Portfolio.

Rule 2a-7 requires that each Portfolio limit its investments to instruments
which Northern determines (pursuant to guidelines established by the Board of
Trustees) to present minimal credit risks and which are "Eligible Securities" as
defined by the SEC and described in the Prospectus.  The Rule also requires that
each Portfolio maintain a dollar-weighted average portfolio maturity (not more
than 90 days) appropriate to its policy of maintaining a stable net asset value
per share and precludes the purchase of any instrument deemed under the Rule to
have a remaining maturity of more than 13 months.  Should the disposition of a
portfolio security result in a dollar-weighted average portfolio maturity of
more than 90 days, the Rule requires a Portfolio to invest its available cash in
such a manner as to reduce such maturity to the prescribed limit as soon as
reasonably practicable.


                DESCRIPTION OF SERVICE SHARES AND PREMIER SHARES

The Trust Agreement permits the Trust's Board of Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of one or more
separate series representing interests in different investment portfolios.  The
Trustees may hereafter create series in addition to the Trust's existing
eighteen series which represent interests in the eighteen respective portfolios.
The Trust Agreement also permits the Board of Trustees to classify or reclassify
any unissued shares into classes within a series.  Pursuant to such authority,
the Trustees have authorized the issuance of an unlimited number of shares of
beneficial interest in three separate classes of shares in each of the
Portfolios:  Shares, Service Shares and Premier Shares.  This Additional
Statement (and the related Prospectus) relates only to the Service Shares and
Premier Shares of the four Portfolios described herein.  For information on the
other class of shares in each Portfolio and

                                      -32-
<PAGE>
 
on the Trust's other investment portfolios, call Goldman Sachs at the toll-free
number on page 1.

Under the terms of the Trust Agreement, each share of each Portfolio is without
par value, represents an equal proportionate interest in the particular
Portfolio with each other share of its class in the same Portfolio and is
entitled to such dividends and distributions out of the income belonging to the
Portfolio as are declared by the Trustees.  Upon any liquidation of a Portfolio,
shareholders of each class of a Portfolio are entitled to share pro rata in the
net assets belonging to that class available for distribution.  Shares do not
have any preemptive or conversion rights.  The right of redemption is described
under "Investing-Redemption of Shares" in the Prospectus and under "Amortized
Cost Valuation" in this Additional Statement.  In addition, pursuant to the
terms of the 1940 Act, the right of a shareholder to redeem shares and the date
of payment by a Portfolio may be suspended for more than seven days (a) for any
period during which the New York Stock Exchange is closed, other than the
customary weekends or holidays, or trading in the markets the Portfolio normally
utilizes is closed or is restricted as determined by the SEC, (b) during any
emergency, as determined by the SEC, as a result of which it is not reasonably
practicable for the Portfolio to dispose of instruments owned by it or fairly to
determine the value of its net assets, or (c) for such other period as the SEC
may by order permit for the protection of the shareholders of the Portfolio. The
Trust may also suspend or postpone the recordation of the transfer of its shares
upon the occurrence of any of the foregoing conditions.  In addition, shares of
each Portfolio are redeemable at the unilateral option of the Trust if the
Trustees determine in their sole discretion that failure to so redeem may have
material adverse consequences to the shareholders of the Portfolio.  Shares when
issued as described in the Prospectus are validly issued, fully paid and
nonassessable, except as stated below.

The proceeds received by each Portfolio for each 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 and constitute the underlying assets of that Portfolio.  The underlying
assets of each Portfolio will be segregated on the books of account, and will be
charged with the liabilities in respect to that Portfolio and with a share of
the general liabilities of the Trust.  Expenses with respect to the Portfolios
are normally allocated in proportion to the net asset value of the respective
Portfolios except where allocations of direct expenses can otherwise be fairly
made.

Rule 18f-2 under the 1940 Act provides that any matter required to be submitted
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

                                      -33-
<PAGE>
 
majority of the outstanding shares of each Portfolio affected by the matter.  A
Portfolio is affected by a matter unless it is clear that the interests of each
Portfolio in the matter are substantially identical or that the matter does not
affect any interest of the Portfolio.  Under the Rule, the approval of an
investment advisory agreement or any change in a fundamental investment policy
would be effectively acted upon with respect to a Portfolio only if approved by
a majority of the outstanding shares of such Portfolio.  However, the Rule also
provides that the ratification of the appointment of independent accountants,
the approval of principal underwriting contracts and the election of Trustees
are exempt from the separate voting requirements stated above.  In addition,
shareholders of each of the classes in a particular investment portfolio have
equal voting rights except that only shares of a particular class of an
investment portfolio will be entitled to vote on matters submitted to a vote of
shareholders (if any) relating to shareholder servicing expenses and transfer
agency fees that are payable by that class.

   
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 shareholders, including the election of Trustees (this
method of voting being referred to as "dollar-based voting").  However, to the
extent required by the 1940 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 meeting.  The shareholders
of the Trust will have voting rights only with respect to the limited number of
matters specified in the Trust Agreement and such other matters as the Trustees
may determine or may be required by law.
    
 
   
The Trust Agreement authorizes the Trustees, without shareholder approval
(except as stated in the next paragraph), 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
substantially all of the assets of a series of the Trust in the securities of
another open-end investment company or pooled portfolio.
    
 
   
The Trust Agreement also authorizes the Trustees, in connection  with the
merger, consolidation, termination or other reorganization
    
 

                                      -34-
<PAGE>
 
   
of the Trust or any series or class, to classify the shareholders of any class
into one or more separate groups and to provide for the different treatment of
shares held by the different groups, provided that such merger, consolidation,
termination or other reorganization is approved by a majority of the outstanding
voting securities (as defined in the 1940 Act) of each group of shareholders
that are so classified.
    
 
   
The Trust Agreement permits the Trustees to amend the Trust Agreement 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 voting provisions of the Trust Agreement; or (iv) that the Trustees
determine to submit to shareholders.
    
 
   
The Trust Agreement 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 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.
    
 
Under the Delaware Business Trust Act (the "Delaware Act"), shareholders are not
personally liable for obligations of the Trust. The Delaware Act entitles a
shareholder of the Trust to the same limitation of liability as is available to
shareholders of private for-profit corporations.  However, no similar statutory
or other authority limiting business trust shareholder liability exists in many
other states.  As a result, to the extent that the Trust or a shareholder is
subject to the jurisdiction of courts in such other states, those courts may not
apply Delaware law and may subject the shareholders to liability. To offset this
risk, the Trust Agreement (i) contains an express disclaimer of shareholder
liability for acts or obligations of the Trust and requires that notice of such
disclaimer be given in each agreement, obligation and instrument entered into or
executed by the Trust or its Trustees and (ii) provides for indemnification out
of the property of the applicable series of the Trust of any shareholder held
personally liable for the obligations of the Trust 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.  Thus, the risk of a shareholder incurring financial
loss beyond his or her investment because of shareholder liability is limited to
circumstances in which all of the following factors are present:

                                      -35-
<PAGE>
 
(1) a court refuses to apply Delaware law; (2) the liability arises under tort
law or, if not, no contractual limitation of liability is in effect; and (3) the
applicable series of the Trust is unable to meet its obligations.

The Trust Agreement provides that the Trustees will not be liable to any person
other than the Trust or a shareholder and that a Trustee will not be liable for
any act as a Trustee.  However, nothing in the Trust Agreement protects a
Trustee against any 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.  The Trust Agreement
provides for indemnification of Trustees, officers and agents of the Trust
unless the recipient is 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.

   
The Trust Agreement provides that each shareholder, by virtue of becoming such,
will be held to have expressly assented and agreed to the terms of the Trust
Agreement and to have become a party thereto.
    
 
   
In addition to the requirements of Delaware law, the Trust Agreement provides
that a shareholder of the Trust may bring a derivative action on behalf of the
Trust 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 Trust, or 10% of the outstanding shares 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 shareholder request and to investigate the basis
of such claim.  The Trust Agreement also provides that no person, other than the
Trustees, who is not a shareholder of a particular series or class shall be
entitled to bring any derivative action, suit or other proceeding on behalf of
or with respect to such series or class.  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 shareholders 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 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 Trust Instrument
with respect to such series or class; and/or (c) may have no power or authority
with respect to any other

Lor, Inc. Pooled Investment
Partnership
 

                    ADDITIONAL INFORMATION CONCERNING TAXES
General

Each Portfolio is treated as a separate corporate entity under the Internal
Revenue Code of 1986, as amended (the "Code"), and intends to qualify as a
regulated investment company.  By following this policy, each Portfolio expects
to eliminate or reduce to a nominal amount the Federal income taxes to which it
may be subject.  If for any taxable year a Portfolio does not qualify for the
special Federal tax treatment afforded regulated investment companies, all of
the Portfolio's taxable income would be subject to tax at regular corporate
rates without any deduction for distributions to shareholders.  In such event,
the Portfolio's distributions (including amounts derived from interest on
Municipal Instruments in the case of the Tax-Exempt Portfolio) would be taxable
as ordinary income for Federal income tax purposes to the Portfolio's
shareholders, to the extent of its current and accumulated earnings and profits,
and would be eligible for the dividends received deduction in the case of
corporate shareholders.

In order to qualify as a regulated investment company for a taxable year under
the Code, each Portfolio must comply with certain requirements.  First, each
Portfolio must distribute to its shareholders an amount equal to at least the
sum of 90% of its investment company taxable income and 90% of its net tax-
exempt

                                      -37-
<PAGE>
 
interest income (if any) (the "Distribution Requirement").  At least 90% of the
gross income of each Portfolio must be derived from dividends, interest,
payments with respect to securities loans, gains from the sale or other
disposition of stock, securities or foreign currencies, and other income
(including, but not limited to, gains from options, futures or forward
contracts) derived with respect to the Portfolio's business of investing in such
stock, securities or currencies (the "Income Requirement").  Finally, at the
close of each quarter of its taxable year, at least 50% of the value of each
Portfolio's assets must consist of cash and cash items, U.S.  Government
securities, securities of other regulated investment companies, and securities
of other issuers (as to which the Portfolio has not invested more than 5% of the
value of its total assets in securities of such issuer and as to which the
Portfolio does not hold more than 10% of the outstanding voting securities of
such issuer) and no more than 25% of the value of each Portfolio's total assets
may be invested in the securities of any one issuer (other than U.S.  Government
securities and securities of other regulated investment companies), or in two or
more issuers which such Portfolio controls and which are engaged in the same or
similar trades or businesses.

Each Portfolio will designate any distribution of the excess of net long-term
capital gain over net short-term capital loss as a capital gain dividend in a
written notice mailed to shareholders within 60 days after the close of the
Portfolio's taxable year.

   
Ordinary income of individuals (including short-term capital gains) is taxable
at a maximum marginal rate of 39.6%, but because of limitations on itemized
deductions otherwise allowable and the phase-out of personal exemptions, the
maximum effective marginal rate of tax for some taxpayers may be higher.  Under
the Taxpayer Relief Act of 1997, for capital gains on securities recognized
after July 28, 1997, the maximum tax rate for individuals is 20% if the property
was held more than 18 months; for property held for more than 12 months, but not
longer than 18 months, the maximum tax rate on capital gains continues to be
28%.  For corporations, long-term capital gains and ordinary income are both
taxable at a maximum marginal rate of 35%.
    
 
A 4% nondeductible excise tax is imposed on regulated investment companies that
fail to currently distribute specified percentages of their ordinary taxable
income and capital gain net income (excess of capital gains over capital
losses).  Each Portfolio intends to make sufficient distributions or deemed
distributions of its ordinary taxable income and any capital gain net income
prior to the end of each calendar year to avoid liability for this excise tax.

The Trust will be required in certain cases to withhold and remit to the U.S.
Treasury 31% of taxable dividends and gross sale proceeds paid to any
shareholder (i) who has provided either an

                                      -38-
<PAGE>
 
incorrect tax identification number or no number at all, (ii) who is subject to
backup withholding by the Internal Revenue Service for failure to report the
receipt of taxable interest or dividend income properly, or (iii) who has failed
to certify to the Trust, when required to do so, that he or she is not subject
to backup withholding or that he or she is an "exempt recipient."

Special Tax Considerations Pertaining to the Tax-Exempt Portfolio

As described above and in the Prospectus, the Tax-Exempt Portfolio is designed
to provide investors with current tax-exempt interest income.  The Portfolio is
not intended to constitute a balanced investment program and is not designed for
investors seeking capital appreciation or maximum tax-exempt income irrespective
of fluctuations in principal.  Shares of the Portfolio 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, would
not gain any additional benefit from the Portfolio's dividends being tax-exempt.
In addition, the Portfolio may not be an appropriate investment for persons or
entities that 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 which regularly uses a part
of such facilities in its 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, or which
occupies more than 5% of the usable area of such facilities or for which such
facilities or a part thereof were specifically constructed, reconstructed or
acquired. "Related persons" include certain related natural persons, affiliated
corporations, partnerships and its partners and an S corporation and its
shareholders.

In order for the Tax-Exempt Portfolio to pay Federal exempt-interest dividends
with respect to any taxable year, at the close of each taxable quarter at least
50% of the aggregate value of the Portfolio must consist of tax-exempt
obligations. An exempt-interest dividend is any dividend or part thereof (other
than a capital gain dividend) paid by the Portfolio and designated as an exempt-
interest dividend in a written notice mailed to shareholders not later than 60
days after the close of the Portfolio's taxable year.  However, the aggregate
amount of dividends so designated by the Portfolio cannot exceed the excess of
the amount of interest exempt from tax under Section 103 of the Code received by
the Portfolio during the taxable year over any amounts disallowed as deductions
under Sections 265 and 171(a)(2) of the Code.  The percentage of total dividends
paid by the Portfolio with respect to any taxable year which qualifies as
Federal exempt-interest dividends will be the same for all

                                      -39-
<PAGE>
 
shareholders receiving dividends from the Portfolio with respect to such year.

Interest on indebtedness incurred by a shareholder to purchase or carry
Portfolio shares generally is not deductible for Federal income tax purposes if
the Portfolio's distributions are not subject to Federal income tax.

Foreign Investors

Foreign shareholders generally will be subject to U.S. withholding tax at a rate
of 30% (or a lower treaty rate, if applicable) on distributions by a Portfolio
of net interest income, other ordinary income, and the excess, if any, of net
short-term capital gain over net long-term capital loss for the year.  For this
purpose, foreign shareholders include individuals other than U.S. citizens,
residents and certain nonresident aliens, and foreign corporations,
partnerships, trusts and estates.  A foreign shareholder generally will not be
subject to U.S. income or withholding tax in respect of proceeds from or gain on
the redemption of shares or in respect of capital gain dividends, provided such
shareholder submits a statement, signed under penalties of perjury, attesting to
such shareholder's exempt status.  Different tax consequences apply to a foreign
shareholder engaged in a U.S. trade or business.  Foreign shareholders should
consult their tax advisers regarding the U.S. and foreign tax consequences of
investing in the Trust.

Conclusion

The foregoing discussion is based on tax laws and regulations which are in
effect on the date of this Additional Statement.  Such laws and regulations may
be changed by legislative or administrative action.  No attempt is made to
present a detailed explanation of the tax treatment of the Portfolios or their
shareholders, and the discussion here and in the Prospectus is not intended as a
substitute for careful tax planning.  Shareholders are advised to consult their
tax advisers with specific reference to their own tax situation, including the
application of state and local taxes.


                                  SERVICE PLAN

The Trust, on behalf of the Portfolios, has adopted a Service Plan (the "Plan")
with respect to the Service Shares and Premier Shares.  Under the Plan, the
Trust, on behalf of the Service Shares and the Premier Shares of each Portfolio,
is authorized to pay to Northern a monthly or quarterly service fee in respect
of (i) administrative support services performed and expenses incurred in
connection with such Portfolio's Service Shares and Premier Shares and (ii)
personal and account maintenance services performed and expenses incurred in
connection with such Portfolio's Premier Shares as set forth below.  The fee
paid for such services (the "Service Fee")

                                      -40-
<PAGE>
 
during any one year shall not exceed: (i) .33% of the average daily net asset
value of the Service Shares of such Portfolio and (ii) .58% of the average daily
net asset value of the Premier Shares of such Portfolio during such period;
provided, however, that the fee paid for personal and account maintenance
services and expenses shall not exceed .25% of the average daily net asset value
of the Premier Shares of such Portfolio for such period.  Northern will
determine the amount of the Service Fee to be paid to one or more brokers,
dealers, other financial institutions or other industry professionals
(collectively, "Service Agents") and the basis on which such payments will be
made.  Payments to a Service Agent will be subject to compliance by the Service
Agent with the terms of the related Plan agreement entered into by the Service
Agent.  The Service Fees payable pursuant to this Plan shall not pertain to
services or expenses which are primarily intended to result in the sales of
Service Shares and Premier Shares.

Payments of the Service Fee with respect to Service Shares and Premier Shares
will be used to compensate or reimburse Northern and the Service Agents for
administrative support services and expenses, which may include without
limitation:  (i) acting or arranging for another party to act, as recordholder
and nominee of Service Shares and Premier Shares of a Portfolio beneficially
owned by Customers; (ii) establishing and maintaining individual accounts and
records with respect to Service Shares and Premier Shares of a Portfolio owned
by Customers; (iii) processing and issuing confirmations concerning Customer
orders to purchase, redeem and exchange Service Shares and Premier Shares of a
Portfolio; (iv) receiving and transmitting funds representing the purchase price
or redemption proceeds of Service Shares and Premier Shares of a Portfolio; (v)
processing dividend payments on behalf of Customers; (vi) forwarding shareholder
communications from the Trust (such as proxy statements and proxies, shareholder
reports, annual and semi-annual financial statements and dividend, distribution
and tax notices); (vii) providing such statistical and other information as may
be reasonably requested by the Trust or necessary for the Trust to comply with
applicable federal or state law; (viii) facilitating the inclusion of a
Portfolio in investment, retirement, asset allocation, cash management or sweep
accounts or similar programs or services offered to their Customers or to
Customers of other Service Agents; (ix) facilitating electronic or computer
trading and/or processing in a Portfolio to their Customers or to Customers of
other Service Agents; and (x) performing any other similar administrative
support services.  Payments of the Service Fee with respect to the Premier
Shares will also be used to compensate or reimburse Northern and the Service
Agents for personal and account maintenance services and expenses, which may
include, without limitation:  (i) providing facilities to answer inquiries and
respond to correspondence with Customers and other investors about the status of
their accounts or about other aspects of the Trust or the applicable Portfolio;
(ii) assisting Customers in completing application forms, selecting dividend and
other account options and

                                      -41-
<PAGE>
 
opening custody accounts with the Service Agents; (iii) providing services to
Customers intended to facilitate, or improve their understanding of the benefits
and risks of, a Portfolio to Customers, including asset allocation and other
similar services; (iv) acting as liaison between Customers and the Trust,
including obtaining information from the Trust and assisting the Trust in
correcting errors and resolving problems; and (v) performing any similar
personal and account maintenance services.

Conflict of interest restrictions (including the Employee Retirement Income
Security Act of 1974) may apply to a Service Agent's receipt of compensation
paid by the Trust in connection with the investment of fiduciary funds in
Service or Premier Shares.  Service Agents, including banks regulated by the
Comptroller of the Currency, the Federal Reserve Board or the Federal Deposit
Insurance Corporation, and investment advisers and other money managers subject
to the jurisdiction of the SEC, the Department of Labor or state securities
commissions, are urged to consult legal advisers before investing fiduciary
assets in Service or Premier Shares.

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 such Plan or the related agreements, approved the Plan and
related agreement for each Portfolio at a meeting called for the purpose of
voting on such Plan and related agreement on January 27, 1998. The Plan and
related agreement will remain in effect until April 30, 1999 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 Board of Trustees in the
manner described above.  The Plan may be terminated as to the Service Class and
the Premier Class at any time by a majority of the non-interested Trustees.  A
service agreement may be terminated at any time, without payment of any penalty,
by vote of a majority of the Trustees as described above or by any party to the
agreement on not more than sixty (60) days' written notice to any other party to
the agreement.  Each service agreement shall terminate automatically if
assigned.  While the Plan is in effect, the selection and nomination of those
Trustees who are not interested persons shall be committed to 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 the Plan will benefit each
Portfolio and holders of Service and Premier Shares of such Portfolio.  The Plan
provides that the Board of Trustees will review, at least quarterly, a written
report of the amount expended under the Plan and the purposes of the
expenditures.

                                   APPENDIX A

                       DESCRIPTION OF SECURITIES RATINGS

The following is a description of the securities ratings of Moody's Investors
Service, Inc. ("Moody's"), Standard & Poor's Ratings Group, Inc., a division of
McGraw Hill ("S&P"), Duff & Phelps Credit Rating Co. ("D&P"), Fitch IBCA, Inc.
("Fitch") and Thomson BankWatch, Inc. ("TBW").

Long-Term Corporate and Tax-Exempt Debt Ratings

The two highest ratings of Moody's for tax-exempt and corporate bonds are Aaa
and Aa.  Tax-exempt and corporate bonds rated Aaa are judged to be of the "best
quality." The rating of Aa is assigned to bonds which are of "high quality by
all standards." Aa bonds are rated lower than Aaa bonds because margins of
protection may not be as large or fluctuations of protective elements may be of
greater amplitude or there may be other elements which make the long-term risks
appear somewhat larger.  Moody's may modify a rating of Aa by adding numerical
modifiers of 1, 2 or 3 to show relative standing within the Aa category.  The
foregoing ratings for tax-exempt bonds are sometimes presented in parentheses
preceded with a "con" indicating the bonds are rated conditionally.  Such
parenthetical rating denotes the probable credit stature upon completion of
construction or elimination of the basis of the condition.  The notation (P)
when applied to forward delivery bonds indicates that the rating is provisional
pending delivery of the bonds.  The rating may be revised prior to delivery if
changes occur in the legal documents or the underlying credit quality of the
bonds.  In addition, Moody's has advised that the short-term credit risk of a
long-term instrument sometimes carries a MIG rating or one of the commercial
paper ratings described below.

   
The two highest ratings of S&P for tax-exempt and corporate bonds are AAA and
AA.  Bonds rated AAA bear the highest rating assigned by S&P to a debt
obligation and the AAA rating indicates that the obligor's capacity to meet its
financial commitment on the obligation is extremely strong.  Bonds rated AA by
S&P demonstrate that the obligor's capacity to meet its financial commitment on
the obligation is strong, and differ from AAA issues only in small degree.  The
AA rating may be modified by an addition of a plus (+) or minus (-) sign to show
relative standing within the major rating category.  S&P may attach the rating
"r" to highlight derivative, hybrid and certain other obligations that S&P
believes may experience high volatility or high variability in expected returns
due to non-credit risks.
    
 
The two highest ratings of D&P for tax-exempt and corporate fixed-income
securities are AAA and AA.  Securities rated AAA are of the highest credit
quality.  The risk factors are considered to be negligible, being only slightly
more than for risk-free U.S.
 
                                      A-1
<PAGE>
 
Treasury debt.  Securities rated AA are of high credit quality.  Protection
factors are strong.  Risk is modest but may vary slightly from time to time
because of economic conditions.  The AA rating may be modified by an addition of
a plus (+) or minus (-) sign to show relative standing within the major rating
category.

   
The two highest ratings of Fitch for tax-exempt and corporate bonds are AAA and
AA.  AAA bonds are considered to be investment grade and of the highest credit
quality.  The obligor is judged to have an exceptionally strong capacity for
timely payment of financial commitments, which is unlikely to be affected by
reasonably foreseeable events.  AA bonds are considered to be investment grade
and of very high credit quality.  These ratings denote a very low expectation of
investment risk and indicate very strong capacity for timely payment of
financial commitments.  Because bonds rated in the AAA and AA categories are not
significantly vulnerable to foreseeable future developments, short-term debt of
these issuers is generally rated F1+.  Plus (+) and minus (-) signs are used
with the AA rating symbol to indicate relative standing within the rating
category.
    
 
The two highest ratings of TBW for corporate bonds are AAA and AA.  Bonds rated
AAA are of the highest credit quality.  The ability of the obligor to repay
principal and interest on a timely basis is considered to be extremely high.
Bonds rated AA indicate a very strong ability on the part of the obligor to
repay principal and interest on a timely basis with limited incremental risk
versus issues rated in the highest category.  These ratings may be modified by
the addition of a plus (+) or minus (-) sign to show relative standing within
the rating categories.  TBW does not rate tax-exempt bonds.

Tax-Exempt Note Ratings

Moody's ratings for state and municipal notes and other short-term obligations
are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade.  MIG-1/VMIG-1
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 denotes high quality.  Margins of
protection are ample although not so large as in the preceding group.

   
S&P describes its SP-1 rating of municipal notes as follows: "Strong capacity to
pay principal and interest.  Those issues determined to possess very strong
characteristics will be given a plus (+) designation." Municipal notes rated SP-
2 are deemed to have satisfactory capacity to pay principal and interest.
    
 
                                      A-2
<PAGE>
 
D&P uses the fixed-income ratings described above under "Corporate and Tax-
Exempt Bond Ratings" for tax-exempt notes and other short-term obligations.

   
Fitch's short-term ratings apply to tax-exempt and corporate debt obligations
that are payable on demand or have original maturities of up to three years,
including commercial paper and municipal and investment notes.  The highest
ratings of Fitch for short-term securities are F1+, F1 and F2.  F1+ securities
possess exceptionally strong credit quality.  Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.  F1
securities possess very strong credit quality.  Issues assigned this rating
reflect an assurance of timely payment only slightly less in degree than issues
rated F1+.  F2 securities possess good credit quality.  Issues carrying this
rating have a satisfactory degree of assurance for timely payment, but the
margin of safety is not as great as the F1+ and F1 ratings.
    
 
TBW does not rate tax-exempt notes.

Short-Term Corporate and Tax-Exempt Debt Ratings

Short-term ratings, set forth below (except TBW's), are applied to tax-exempt as
well as taxable debt.

   
Moody's short-term debt ratings are opinions of the ability of issuers to repay
punctually senior debt obligations not having an original maturity in excess of
one year.  Issuers rated Prime-1 (or related supporting institutions) in the
opinion of Moody's have a superior capacity for repayment of short-term
promissory obligations.  Issuers rated Prime-2 (or related supporting
institutions) are considered to have a strong capacity for repayment of short-
term promissory obligations.
    
 
   
S&P's commercial paper ratings are current assessments of the likelihood of
timely payment of debt considered short-term in the relevant market.  The A-1
designation indicates that the obligor's capacity to meet its financial
commitment is strong.  Those issues for which the obligor's capacity to meet its
financial commitment is extremely strong will be denoted with a plus (+) sign
designation.  The A-2 designation indicates that the obligor's capacity to meet
its financial commitment is satisfactory.  However, the relative degree of
safety is not as high as for issues designated A-1.
    
 
   
The two highest ratings of D&P for commercial paper are D-1 and D-2.  D&P
employs three designations, D-1 plus, D-1 and D-1 minus, within the highest
rating category.  D-1 plus indicates highest certainty of timely payment.
Short-term liquidity including internal operating factors, and/or ready access
to alternative sources of funds, is judged to be outstanding, and safety is just
below risk-free U.S.  Treasury short-term obligations.  D-1
    
 
                                      A-3

indicates very high certainty of timely payment.  Liquidity factors are
excellent and supported by strong fundamental protection factors.  Risk factors
are considered to be minor.  D-1 minus indicates high certainty of timely
payment.  Liquidity factors are strong and supported by good fundamental
protection factors.  Risk factors are very small.  D-2 indicates good certainty
of timely payment.  Liquidity factors and company fundamentals are sound.
Although ongoing funding needs may enlarge total financing requirements, access
to capital markets is good.  Risk factors are small.
    
 
Fitch uses the short-term ratings described above under "Tax-Exempt Note
Ratings" for commercial paper.

TBW's short-term ratings assess the likelihood of an untimely or incomplete
payment of principal or interest of unsubordinated debt instruments having a
maturity of one year or less which are issued by Shared States commercial banks,
thrifts and non-bank banks; non-Shared States banks; and broker-dealers and
other financial institutions.  The two highest short-term ratings of TBW are
TBW-1 and TBW-2.  Debt rated TBW-1 indicates a very high degree of likelihood
that principal and interest will be paid on a timely basis.  The TBW-2
designation indicates that while the degree of safety regarding timely payment
of principal and interest is strong, the relative degree of safety is not as
high as for issues rated TBW-1.

              ADDENDUM NO. 7 TO THE INVESTMENT ADVISORY AGREEMENT
              ---------------------------------------------------

     This Addendum, dated as of the 27th day of January, 1998, is entered into 
between THE BENCHMARK FUNDS (the "Trust"), a Massachusetts business trust, and 
THE NORTHERN TRUST COMPANY (the "Investment Adviser"), and Illinois state bank.

Short-Intermediate Bond Portfolio, Bond Portfolio, Intermediate Bond Portfolio, 
Equity Index Portfolio, Small Company Index Portfolio, Diversified Growth 
Portfolio, Focused Growth Portfolio, Balanced Portfolio, International Growth 
Portfolio, International Bond Portfolio and International Equity Index 
Portfolio;

     WHEREAS, Section 1(b) of the Advisory Agreement provides that in the event 
the Trust establishes one or more additional investment portfolios with respect 
to which it desires to retain the Investment Adviser to act as investment 
adviser under the Advisory Agreement, the Trust shall so notify the Investment 
Adviser in writing and if the Investment Adviser is willing to render such 
services it shall notify the Trust in writing, and the compensation to be paid 
to the Investment Adviser shall be that which is agreed to in writing by the 
Trust and the Investment Adviser, and

     WHEREAS, pursuant to Section 1(b) of the Advisory Agreement, the Trust has 
notified the Investment Adviser that it is establishing the Global Asset 
Portfolio (the "Portfolio"), and that it desires to retain the Investment 
Adviser to act as the investment adviser therefor, and the Investment Adviser 
has notified the Trust that it is willing to serve as investment adviser for the
Portfolio;

     NOW THEREFORE, the parties hereto, intending to be legally bound, hereby
agree as follows:

     1.   Appointment. The Trust hereby appoints the Investment Adviser to act
          as investment adviser to the Trust for the Portfolio for the period
          and on the terms set forth in the Advisory Agreement. The Investment
          Adviser hereby accepts such appointment and agrees to render the 
          services set forth in the Advisory Agreement for the compensation
          herein provided. Without limiting the generality of the foregoing, the
          Investment Adviser shall (i) evaluate the attributes of any investment
          company in which the Portfolio may invest and (ii) determine the
          amount of the Portfolio's assets that are invested in any one or more
          investment companies from time to time.

     2.   Duties. The Investment Adviser shall perform the following duties with
          respect to common and preferred stocks of the Portfolio in lieu of
          clauses (ii) and (iii) of paragraph 3(a) of the Advisory Agreement:

               (a)  The Investment Adviser shall place orders pursuant to its
          determination either directly with the issuer or with any broker
          and/or dealer or other persons who deal in the securities in which the
          portfolio in question is trading. In executing portfolio transactions
          and selecting brokers or dealers, the Investment Adviser shall use its
          best judgment to obtain the best overall terms available. In assessing
          the best overall terms available for any transaction, the Adviser
          shall consider all factors it deems relevant, including the breadth of
          the market in the

                                       1
<PAGE>
 
          security, the price of the security, the financial condition and
          execution capability of the broker or dealer, and the reasonableness
          of the commission, if any, both for the specific transaction and on a
          continuing basis. In evaluating the best overall terms available and
          in selecting the broker or dealer to execute a particular transaction,
          the Adviser may also consider the brokerage and research services (as
          those terms are defined in Section 28(e) of the Securities Exchange
          Act of 1934) provided to any Portfolio and/or other accounts over
          which the Adviser and/or an affiliate of the Adviser exercises
          investment discretion;

               (b)  The Investment Adviser may, on occasions when it deems the
          purchase or sale of a security to be in the best interests of a
          Portfolio as well as other fiduciary or agency accounts managed by the
          Investment Adviser, aggregate, to the extent permitted by applicable
          laws and regulations, the securities to be sold or purchased in order
          to obtain best overall terms available execution. 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 Investment
          Adviser in the manner it considers to be most equitable and consistent
          with its fiduciary obligations to such Portfolio and to such other
          accounts.

     3.   Compensation. For the services provided and the expenses assumed
          pursuant to the Advisory Agreement, the Trust will pay the Investment
          Adviser, and the Investment Adviser will accept as full compensation
          therefor from the Trust, a fee at an annual rate of .60% of average
          net assets for the Global Asset Portfolio. The fee will be computed
          based on net assets on each day and will be paid to the Investment
          Adviser monthly. Such fee as is attributable to the Portfolio shall be
          a separate charge to such Portfolio and shall be the several (and not
          joint or joint and several) obligation of the Portfolio.

     4.   Capitalized Terms. From and after the date hereof, the term
          "Portfolios" as used in the Advisory Agreement shall be deemed to
          include the Global Asset Portfolio. Capitalized terms used herein and
          not otherwise defined shall have the meanings ascribed to them in the
          Advisory Agreement.

     5.   Miscellaneous. Except to the extent supplemented hereby, the Advisory
          Agreement shall remain unchanged and in full force and effect, and is
          hereby ratified and confirmed in all respects as supplemented hereby.

     IN WITNESS WHEREOF, the undersigned have executed this Addendum as of the 
date and year first above written.

     WHEREAS, the Trust desires to retain Northern and RCB Trust (the

     NOW, THEREFORE, in consideration of the premises and mutual covenants

                    a Portfolio's assets, including the purchase, retention and
                    disposition thereof.  In this regard, the Adviser shall
                    provide for:

                    (i)  a continuous investment program for a Portfolio, the
                         determination from time to time of which investments or
                         securities will be purchased, retained or sold by a
                         Portfolio and which portion of the assets will be

                         condition and execution capability of the broker or

                         any, both for the specific transaction and on a
                         continuing basis. In evaluating the best overall terms

                         execute a particular transaction, the brokerage and
                         research services (as those terms are defined in
                         section 28(e) of the Securities Exchange Act of 1934)
                         provided to the Portfolio and/or other accounts over
                         which an Adviser, sub-adviser and/or affiliate
                         exercises investment discretion may be considered. In
                         addition, any person executing portfolio transactions
                         may, when it deems the purchase or sale of a security
                         to be in the best interests of a Portfolio as well as
                         other fiduciary or agency accounts managed by it,
                         aggregate, to the extent permitted by applicable laws
                         and regulations, the securities to be sold or purchased
                         in order to obtain best overall terms available
                         execution. In such event, allocation of the securities
                         so purchased or sold, as well as the expenses incurred
                         in the transaction, will be made in the manner
                         considered to be most equitable and consistent with the
                         fiduciary obligations owed to the Portfolio and to such
                         other accounts.

               (b)  The Advisers shall perform their duties under this Agreement
                    either by taking such actions themselves or by delegating
                    some or all of their duties to one or more sub-advisers
                    pursuant to a written sub-advisory agreement or agreements.
                    Each such sub-advisory agreement shall be approved by the
                    Board of Trustees of the Trust and the unitholders of the
                    Portfolio in accordance with and to the extent required by
                    the 1940 Act or any rule or order of the SEC.  The Advisers
                    will be solely responsible for payment of any fees,
                    compensation or expenses to any such sub-adviser under any
                    such sub-advisory agreement, and a Portfolio shall have no
                    
                                      -4-

                    liability therefor.  Notwithstanding the delegation of any
                    of their duties to any sub-adviser, the Advisers, subject to
                    review and approval by the Board of Trustees of the Trust,
                    shall:

                    (i)    set a Portfolio's overall investment strategies;

                    (ii)   monitor and evaluate the performance of sub-
                           advisers;

                    (iii)  recommend to the Board of Trustees whether an
                           agreement with any proposed or current sub-adviser
                           should be approved, modified or terminated;

                    (iv)   as deemed appropriate by the Advisers, allocate and
                           re-allocate a Portfolio's assets among sub-advisers;
                           and

                    (v)    oversee compliance by a Portfolio's sub-advisers with
                           the Portfolio's investment objective, policies and
                           restrictions.

          4.   Other Covenants.
               --------------- 
               (a)  The Advisers, in connection with their rights and duties
                    with respect to a Portfolio,

                    (i)  shall use the care, skill, prudence and diligence under
                         the circumstances then prevailing that a prudent person
                         acting in a like capacity and familiar with such
                         matters would use in the conduct of an enterprise of a
                         like character and with like aims; and

                    (ii) shall act in conformity with the Trust Agreement, By-
                         Laws, Registration Statement, Prospectus and Statement
                         of Additional Information and the instructions and
                         directions of the Trustees of the Trust, and will use
                         their best efforts to comply with and conform to the
                         requirements of the 1940 Act and all other applicable
                         federal and state laws, regulations and rulings.

                                      -5-

               (b)  The Advisers shall:

                    (i)  comply with all applicable Rules and Regulations of the
                         SEC and will in addition conduct their activities under
                         this Agreement in accordance with other applicable law;
                         and

                    (ii) maintain a policy and practice of conducting their
                         investment advisory services hereunder independently of
                         the commercial banking operations of Northern and any
                         of its affiliated banks.  When investment
                         recommendations are made for a Portfolio, the
                         investment advisory personnel will not inquire or take
                         into consideration whether the issuer of securities
                         proposed for purchase or sale for the Portfolio's
                         account are customers of the commercial banking
                         department of Northern or any of its affiliated banks.

               (c)  The Advisers shall not, unless permitted by the SEC:

                    (i)  permit a Portfolio to execute transactions with the
                         Advisers or Goldman, Sachs & Co.; or

                    (ii) permit a Portfolio to purchase certificates of deposit
                         of Northern or its affiliate banks, commercial paper
                         issued by Northern's parent holding company or other
                         securities issued or guaranteed by Northern, its parent
                         holding company or their subsidiaries or affiliates.

               (d)  The Advisers shall render to the Trustees of the Trust such
                    periodic and special reports as the Trustees may reasonably
                    request.

               (e)  The services of the Advisers hereunder are not deemed
                    exclusive and the Advisers shall be free to render similar
                    services to others (including other investment companies) so
                    long as their services under this Agreement are not impaired
                    thereby.

          5. Expenses. During the term of this Agreement, the Advisers shall pay
all costs incurred by them in connection with

                                      -6-
<PAGE>
 
the performance of their duties under this Agreement, other than the cost
(including taxes, brokerage commissions and other transactions costs, if any) of
securities purchased or sold for a Portfolio.

          6.   Compensation.
               ------------ 
               (a)  For the services provided and the expenses assumed by the
                    Advisers pursuant to this Agreement with respect to the
                    Current Portfolio, the Trust shall pay as full compensation
                    therefor an aggregate fee to the Advisers at an annual rate
                    of 1.00% of the Current Portfolio's average net assets.

               (b)  The fee shall be computed based on net assets on each day
                    and shall be paid to the Advisers monthly.  Such fee as is
                    attributable to a Portfolio shall be a separate charge to
                    the Portfolio and shall be the several (and not joint or
                    joint and several) obligation of the Portfolio.

          7.   Books and Records. The Advisers agree to maintain, and preserve
for the periods prescribed by Rule 31a-2 of the SEC under the 1940 Act, such
records as are required to be maintained by Rule 31a-1 of the SEC under the 1940
Act (other than clause (b)(4) and paragraphs (c), (d) and (e) thereof). The
Advisers further agree that all records which they maintain for the Trust are
the property of the Trust and they shall surrender promptly to the Trust any of
such records upon the Trust's request.

          8.   Indemnification.
               --------------- 

               (a)  The Trust hereby agrees to indemnify and hold harmless the
                    Advisers, their directors, officers, and employees and each
                    person, if any, who controls either of them (collectively,
                    the "Indemnified Parties") against any and all losses,
                    claims, damages or liabilities, joint or several, to which
                    they or any of them may become subject under the 1933 Act,
                    the Securities Exchange Act of 1934 or other federal or
                    state statutory law or regulation, at common law or
                    otherwise, insofar as such losses, claims, damages or
                    liabilities (or actions in respect thereof) arise out of or
                    are based upon:

                    (i)  any untrue statement or alleged untrue statement of a
                         material fact or any

                                      -7-
<PAGE>
 
                         omission or alleged omission to state a material fact
                         required to be stated or necessary to make the
                         statements made not misleading in the Registration
                         Statement, the Prospectus, the Statement of Additional
                         Information, or any application or other document filed
                         in connection with the qualification of the Trust or
                         Units of the Trust under the Blue Sky or securities
                         laws of any jurisdiction ("Application"), except
                         insofar as such losses, claims, damages or liabilities
                         (or actions in respect thereof) arise out of or are
                         based upon any such untrue statement or omission or
                         alleged untrue statement or omission either pertaining
                         to a breach of the Advisers' duties in connection with
                         this Agreement or made in reliance upon and in
                         conformity with information furnished by, through or on
                         behalf of the Advisers for use in connection with the
                         Registration Statement, any Application, the Prospectus
                         or the Statement of Additional Information; or

                    (ii) subject to clause (i) above, the Advisers acting in
                         accordance with the terms hereof;

                    and the Trust shall reimburse each Indemnified Party for any
                    legal or other expense incurred by such Indemnified Party in
                    connection with investigating or defending any such loss,
                    claim, damages, liability or action.

               (b)  If the indemnification provided for in paragraph 8(a) is due
                    in accordance with the terms of such paragraph but is for
                    any reason held by a court to be unavailable from the Trust,
                    then the Trust shall contribute to the aggregate amount paid
                    or payable by the Trust and the Indemnified Parties as a
                    result of such losses, claims, damages or liabilities (or
                    actions in respect thereof) in such proportion as
                    appropriate to reflect (i) the relative benefits received by
                    the Trust and such Indemnified Parties in connection with
                    the operation of the Trust, (ii) the relative fault of the
                    Trust and such Indemnified

                                      -8-
<PAGE>
 
                    Parties, and (iii) any other relevant equitable
                    considerations. The Trust and the Advisers agree that it
                    would not be just and equitable if contribution pursuant to
                    this subparagraph (b) were determined by pro rata allocation
                    or other method of allocation which does not take account of
                    the equitable considerations referred to above in this
                    subparagraph (b). The amount paid or payable as a result of
                    the losses, claims, damages or liabilities (or actions in
                    respect thereof) referred to above in this subparagraph (b)
                    shall be deemed to include any legal or other expense
                    incurred by the Trust and the Indemnified Parties in
                    connection with investigating or defending any such loss,
                    claim, damage, liability or action. No person guilty of
                    fraudulent misrepresentation (within the meaning of Section
                    11(f) of the 1933 Act) shall be entitled to contribution
                    from any person who was not guilty of such fraudulent
                    misrepresentation.

               (c)  It is understood, however, that nothing in this paragraph 8
                    shall protect any Indemnified Party against, or entitle any
                    Indemnified Party to indemnification against, or
                    contribution with respect to, any liability to the Trust or
                    its Unitholders to which such Indemnified Party is subject,
                    by reason of its willful misfeasance, bad faith or gross
                    negligence in the performance of its duties, or by reason of
                    a reckless disregard to its obligations and duties, under
                    this Agreement or otherwise, to an extent or in a manner
                    inconsistent with Section 17 of the 1940 Act.

          9. Duration and Termination. Insofar as the holders of Units
representing the interests in the Current Portfolio are affected by this
Agreement, it shall continue, unless sooner terminated as provided herein, until
April 30 of the year following the year first above written, and, insofar as the
holders of Units representing the interests in each of the other Portfolios are
affected by this Agreement, it (as supplemented by the terms specified in any
notice and agreement pursuant to paragraph 1(b) hereof) shall continue (assuming
approval by the initial holder(s) of Units of such Portfolio) until April 30 of
the year following the year in which the Portfolio becomes a Portfolio
hereunder, and with respect to each Portfolio thereafter shall continue
automatically for periods of one year so long as each such latter continuance is
approved at least

                                      -9-
<PAGE>
 
annually (a) by the vote of a majority of the Trustees of the Trust who are not
parties to this Agreement or interested persons (as defined by the 1940 Act) of
any such party, cast in person at a meeting called for the purpose of voting on
such approval, and (b) by the Trustees of the Trust or by vote of a majority of
the outstanding Units (as defined with respect to voting securities in the 1940
Act) representing the interests in such Portfolio; provided, however, that this
Agreement may be terminated by the Trust as to any Portfolio at any time,
without the payment of any penalty, by vote of a majority of the Trustees of the
Trust or by vote of a majority of the outstanding Units (as so defined)
representing the interests in the Portfolio affected thereby on 60 days' written
notice to the Advisers, or by the Advisers at any time, without the payment of
any penalty, on 60 days' written notice to the Trust.  This Agreement shall
automatically and immediately terminate in the event of its assignment (as
defined by the 1940 Act).

          10. Name of the Trust. Northern agrees that the name "The Benchmark"
may be used in the name of each Portfolio and that such name, any related logos
and any service marks containing the words "The Benchmark" may be used in
connection with the Portfolio's business only for so long as this Agreement
(including any continuance or amendment hereof) remains in effect and that such
use shall be royalty free. At such time as this Agreement shall no longer be in
effect, each Portfolio shall cease such use. The Trust acknowledges that it has
no rights to the name "The Benchmark," such logos or service marks other than
those granted in this paragraph and that Northern reserves to itself the right
to grant the nonexclusive right to use the name "The Benchmark," such logos or
service marks to any other person, including, but not limited to, another
investment company.

          11. Status of Advisers as Independent Contractors. The Advisers shall
for all purposes herein be deemed to be independent contractors and shall,
unless otherwise expressly provided herein or authorized by the Trustees of the
Trust from time to time, have no authority to act for or represent the Trust in
any way or otherwise be deemed agents of the Trust.

          12. Amendment of Agreement. This Agreement may be amended by mutual
consent, but the consent of the Trust must be approved (a) by vote of a majority
of those Trustees of the Trust who are not parties to this Agreement or
interested persons (as defined in the 1940 Act) of any such party, cast in
person at a meeting called for the purpose of voting on such amendment, and (b)
by vote of a majority of the outstanding Units (as defined with respect to
voting securities by the 1940 Act) representing the interests in each Portfolio
affected by such amendment.

          13. Unitholder Liability. This Agreement is executed by or on behalf
of the Trust with respect to each Portfolio and

                                      -10-
<PAGE>
 
the obligations hereunder are not binding upon any of the Trustees, officers or
Unitholders of the Trust individually but are binding only upon the Trust and
its assets and property. All obligations of the Trust under this Agreement shall
apply only on a Portfolio-by-Portfolio basis, and the assets of one Portfolio
shall not be liable for the obligations of another Portfolio.

          14. Miscellaneous. The Trust's Declaration of Trust as amended to date
is on file with the Secretary of The Commonwealth of Massachusetts. The captions
in this Agreement are included for convenience of reference only and in no way
define or delimit any of the provisions hereof or otherwise affect their
construction or effect. If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder of this
Agreement shall not be affected thereby. This Agreement shall be construed in
accordance with applicable federal law and (except as to paragraph 13 hereof
which shall be construed in accordance with the laws of The Commonwealth of
Massachusetts) the laws of the State of Illinois and shall be binding upon and
shall inure to the benefit of the parties hereto and their respective successors
(subject to the last sentence of paragraph 9) and, to the extent provided in
paragraph 8 hereof, each Indemnified Party. Anything herein to the contrary
notwithstanding, this Agreement shall not be construed to require, or to impose
any duty upon, any party to do anything in violation of any applicable laws or
regulations. Any provision in this Agreement requiring compliance with any
statute or regulation shall mean such statute or regulation as amended and in
effect from time to time.

          IN WITNESS WHEREOF, the parties hereto have caused this instrument to
be executed as of the day and year first above written.

  AGREEMENT made this 5th day of October, 1990 between THE BENCHMARK FUNDS, a
Massachusetts business trust (the "Trust"), and GOLDMAN, SACHS & CO., a New York
limited partnership (the "Distributor").


                                 W I T N E S S E T H:


  WHEREAS, the Trust is engaged in business as an open-end, management
investment company and is so registered under the Investment Company Act of
1940, as amended (the "1940 Act"); and

  WHEREAS, the Trust is authorized to issue units of beneficial interest
("Units") in separate series with each such series representing the interests in
a separate portfolio of securities and other assets; and

  WHEREAS, the Trust presently intends to offer Units in four portfolios, the
Diversified Assets Portfolio, the Government Portfolio, the Tax-Exempt
Portfolio, and the Government Select Portfolio (such Portfolios together with
all other series subsequently established by the Trust and made subject to this
Agreement being herein referred to as the "Portfolios"); and

  WHEREAS, the Trust desires to retain the Distributor to act as distributor to
provide for the sale and distribution of Units of the Portfolios, and the
Distributor is willing to so render such services;

  NOW, THEREFORE, in consideration of the premises and mutual covenants herein
contained and other good and valuable consideration, receipt whereof is hereby
acknowledged, the parties hereto agree as follows:

  1.  Appointment of Distributor.  The Trust hereby appoints the Distributor as
exclusive distributor of the Units of each of the Portfolios on the terms and
for the periods set forth in this Agreement. The Distributor hereby accepts such
appointment and agrees to render the services and perform the duties set forth
in this paragraph 1 and in paragraph 2 without compensation.
<PAGE>
 
     2.   Duties as Distributor. The following provisions shall apply to the
Distributor's obligations as distributor under this Agreement;

          (a)  The Trust agrees to sell Units of each of the Portfolios through
     the Distributor, as agent, from time to time during the term of this
     Agreement upon the terms and at the current offering price described in the
     Prospectus and Statement of Additional Information [as those terms are
     defined in the Administration Agreement of even date herewith between the
     Trust and the Distributor (the "Administration Agreement")]. Such sales
     may, however, be suspended whenever in the judgment of the Trust it is in
     its best interests to do so;

          (b)  The Distributor will hold itself available to receive or will
     arrange for the receipt of orders for the purchase of Units of each
     Portfolio and will (and shall have the authority to) receive and accept or
     reject or arrange for the receipt and acceptance or rejection of such
     orders on behalf of the Trust in accordance with the provisions of the
     Prospectus and Statement of Additional Information.

          (c) The Distributor shall not be obligated to sell any certain number
     of Units of any Portfolio;

          (d)  In performing its duties hereunder, the Distributor shall act in
     conformity with the Trust Agreement, By-Laws, Registration Statement,
     Prospectus and Statement of Additional Information (as such terms are
     defined in the Administration Agreement) and with the instructions and
     directions of the Trustees of the Trust, and will use its best efforts to
     comply with and conform to the requirements of the 1940 Act and all other
     applicable federal and state laws, regulations and rulings including
     without limitation any exemptive order issued by the Securities and
     Exchange Commission to which the Trust may be subject;

          (e) The Distributor shall be free to render to others services similar
     to those rendered to the Trust hereunder so long as the Distributor's
     services hereunder are not impaired thereby.

          (f)  The Distributor agrees to maintain, and preserve for the 

                                      -2-

     periods prescribed by Rule 31a-2 of the Securities and Exchange Commission
     under the 1940 Act, such records as are required to be maintained by Rule
     31a-1(d) under the 1940 Act.

     3.   Distribution Costs. During the term of this Agreement, the Distributor
will pay the following costs:

          (a) Costs of all sales presentations, mailings, advertising and any
     other distribution efforts by the Distributor with respect to the Units of
     each of the Portfolios. Such costs shall not be deemed to include the costs
     of preparing and setting in type Prospectuses, Statements of Additional
     Information, proxy material, reports and notices and the printing and
     distributing the same to existing Unitholders and regulatory authorities;
     and

          (b) Compensation of any personnel of the Distributor for activities in
     connection with the distribution or sale of the Units of each of the
     Portfolios.

     4.   Duration and Termination. This Agreement shall continue, unless sooner
terminated as provided herein, until April 30, 1992 and thereafter shall
continue automatically for periods of one year so long as each such latter
continuance is approved at least annually (a) by the vote of a majority of the
Trustees of the Trust who are not parties to this Agreement or interested
persons (as defined in the 1940 Act) of any such party, cast in person at a
meeting called for the purpose of voting on such approval, and (b) by the
Trustees of the Trust or by vote of a majority of the outstanding Units (as
defined with respect to voting securities in the 1940 Act) representing the
interests in the Portfolios; provided, however, that this Agreement may be
terminated by the Trust as to any or all Portfolios at any time, without the
payment of any penalty, on 60 days' written notice to the Distributor or by the
Distributor at any time, without the payment of any penalty, on 60 days' written
notice to the Trust. This Agreement will automatically and immediately terminate
in the event of its assignment (as defined in the 1940 Act).

persons (as defined in the 1940 Act) of any such party, cast in person at a
meeting called for the purpose of voting on such amendment.

     6.   Unitholder Liability.  This Agreement is executed by or on behalf of
the Trust with respect to each of the Portfolios and the obligations hereunder
are not binding upon any of the Trustees, officers or Unitholders of the Trust
individually but are binding only upon the Portfolio to which such obligations
pertain and the assets and property of such Portfolio.

     7.   Miscellaneous.  The Trust's Declaration of Trust is on file with the
Secretary of the Commonwealth of Massachusetts. The captions in this Agreement
are included for convenience of reference only and in no way define or delimit

If any provision of this Agreement shall be held or made invalid by a court
decision, statute, rule or otherwise, the remainder of this Agreement shall not
be affected thereby. This Agreement shall be construed in accordance with
applicable federal law and (except as to paragraph 6 hereof which shall be
construed in accordance with the laws of the Commonwealth of Massachusetts) the
laws of the State of Illinois and shall be binding upon and shall inure to the
benefit of the parties hereto and their respective successors, subject to
paragraph 4 hereof.

                                 CUSTODIAN AGREEMENT

     Agreement dated this 8th day of June, 1992 between The Benchmark Funds, a
Massachusetts business trust (the "Trust"), and The Northern Trust Company, an
Illinois state bank ("Northern").

     1.   Appointment of Custodian. The Trust hereby appoints Northern custodian
of all securities (including repurchase agreements) and cash now owned or
hereafter acquired by the Trust, and Northern hereby accepts such appointment,
upon the terms and conditions set forth in this Agreement. The Trust agrees
promptly to deliver and pay, or cause to be delivered and paid, to Northern, as
custodian, all securities and cash now owned or hereafter acquired by the Trust.
It is understood that (a) the Trust is an open-end, management investment
company registered under the Investment Company Act of 1940 ("1940 Act") as a
series company with six portfolios but with the ability to create additional
portfolios (the initial portfolios and each such additional portfolio being
referred to herein as a "Portfolio"), and all such portfolios being collectively
referred to herein as the "Portfolios"), and (b) pursuant to section 18(f)(2) of
the 1940 Act each series of the Trust's Units [as defined in Trust's Agreement
and Declaration of Trust (the "Trust Agreement")], representing the interest in
a Portfolio, is preferred over all other series in respect of the assets
specifically allocated to such Portfolio.

     2.   Custody of Cash; Separate Accounts.

          (a)  Accounts. Northern will hold all cash of each Portfolio, in a
               separate account or accounts in the name of such Portfolio,
               subject only to draft or order by Northern in accordance with the
               terms of this Agreement. If and when authored by proper
               instructions of the Trustees or Officers of the Trust in
               accordance with a vote of the majority of the Trustees of the
               Trust, Northern may open and maintain an additional account or
               accounts in such other banks or trust companies as may be
               designated by such instructions, provided that such account or
               accounts shall be in the name of Northern in its capacity as
               custodian and subject only to its draft or order in accordance
               with the terms of this Agreement.

          (b)  Proceeds of Sale of Units of Trust. Upon receipt of funds for the
               purchase of Units of
<PAGE>
 
               any Portfolio, Northern shall promptly deposit the purchase price
               in the account or accounts maintained pursuant to Section 2A
               hereof.

          (c)  Collections. Unless otherwise directed by proper instructions
               from the Trustees or Officers of the Trust, Northern shall
               collect, receive and deposit in the account or accounts
               maintained pursuant to Section 2A hereof all income, principal
               and other payments in respect of the securities held by it under
               this Agreement and, subject to the other provisions of this
               Agreement, do all other things necessary or proper in connection
               with the collection of such income, principal and other payments.
               Without limiting the generality of the foregoing, Northern shall:

               (i)    present for payment by the date of payment all coupons and
                      other income items requiring presentation;

               (ii)   present for payment all securities which may mature or be
                      called, redeemed, retired or otherwise become payable by
                      the date such securities become payable;

               (iii)  endorse and deposit for collection, on behalf of the
                      Trust, checks, drafts or other negotiable instruments no
                      later than the next business day as received;

               (iv)   execute ownership and other certificates and affidavits
                      for all Federal and State tax purposes in connection with
                      the collection of income; and

               (v)    notify the Trust as soon as reasonably practicable
                      whenever income, principal or other payments due on
                      securities are not collected in due course.

     In any case in which Northern does not receive any such due and unpaid
income, principal or other payment within a reasonable time after it has made
proper demands for the same, it shall so notify the Trust in writing, including
copies of all demand letters, any written responses thereto, and memoranda of
telephonic demands and oral responses to written and telephonic demands, and
await proper instructions from the Trustees or Officers of the Trust. Northern
shall not be obliged to take legal action for collection unless and until
reasonably indemnified to its satisfaction.

                                      -2-

               persons, firms, corporations or other Portfolios, pursuant to the

                   notify the Administrator of the result of such computation
                   and determination.

                   Unless advised otherwise by proper instructions from the
                   Trustees or Officers of the Trust, Northern shall also
                   calculate at the times specified in the Trust's then Current
                   Prospectus the net income of each Portfolio and shall
                   promptly advise the Administrator of the results of such
                   calculation. Such calculation shall be made in accordance
                   with the Trust's then Current Prospectus.

      8.     Appointment of Agents and Sub-Custodians.

             (a)   Appointment of Agents.  Northern, as custodian, may at any
                   time or times appoint (and may at any time remove) in
                   accordance with the 1940 Act any other bank, trust company or
                   responsible commercial agent as its agent to carry out such
                   of the provisions of this Agreement as Northern may from time
                   to time direct, provided that the appointment of such agent
                   shall not relieve Northern of any of its responsibilities
                   under this Agreement.

             (b)   Appointment of Sub-Custodian. Northern, as custodian, may
                   from time to time employ one or more sub-custodians, but only
                   in accordance with the terms and conditions set forth in a
                   resolution of the Trustees of the Trust authorizing the
                   appointment of each particular sub-custodian, it being
                   understood and agreed that: (i) Northern shall have no more
                   responsibility or liability to the Trust on account of any
                   actions or omissions of any sub-custodian so employed that
                   such sub-

                                     -11-
<PAGE>
 
                   custodian has to Northern; and (ii) the responsibility or
                   liability of the sub-custodian to Northern shall conform to
                   the resolution of the Trustees of the Trust authorizing the
                   appointment of the particular sub-custodian.

      9.     Proper Instructions.

             (a)   Proper Instructions Generally.  Proper instructions shall be
                   deemed to have been issued upon issuance of written
                   instructions signed by not less than one officer and one
                   responsible employee of Northern which in the case of each
                   such officer and employee Northern's Board of Directors shall
                   have from time to time authorized to give the particular
                   class of instructions in question. Different persons may be
                   authorized to give instructions for different purposes.

             (b)   Proper Instructions from the Trustees or Officers of the
                   Trust. Proper instructions from the Trustees or Officers of
                   the Trust shall be deemed to have been issued upon receipt by
                   Northern of written instructions (including receipt of
                   facsimile) signed by a majority of the Trustees of the Trust
                   or by not less than two of the Officers of the Trust
                   designated from time to time by resolution of the Trustees.
                   Such instructions shall be deemed proper instructions as that
                   term is used in this Agreement in addition to also being
                   deemed proper instructions from the Trustees or Officers of
                   the Trust. A certificate executed by the Secretary or
                   Assistant Secretary of the Trust as to the persons serving as
                   Trustees and/or who are Officers of the Trust designated as
                   set forth above may be received and accepted by Northern as
                   conclusive evidence of those persons who are such Trustees
                   and/or Officers and may be considered to be accurate until
                   receipt of written notice (or oral notice followed by written
                   confirmation within seven days) to the contrary. In the case
                   of conflict between Instructions under Section 9A and under
                   this Section 9B, those given pursuant to this Section 9B
                   shall prevail upon receipt by Northern.

      10.    Compensation: Reimbursement.  The Trust shall pay to 

                                     -12-
<PAGE>
 
Northern, as custodian, the compensation and expense reimbursement set forth in
Exhibit A hereto.

     11.   Duration and Termination. Insofar as the holders of Units
representing the interests in the Trust's initial Portfolios are affected by
this Agreement, it shall continue, unless sooner terminated as provided herein,
until April 30, 1993, and, insofar as the holders of Units representing the
interests in each additional Portfolio are affected by this Agreement, it shall
continue until April 30 of the year following the year in which the Portfolio
becomes a Portfolio hereunder, and, for each such Portfolio, thereafter shall
continue automatically for periods of one year so long as each such latter
continuance is approved at least annually (a) by the vote of a majority of the
Trustees of the Trust who are not parties to this Agreement or interested
persons (as defined by the 1940 Act) of any such party, cast in person at a
meeting called for the purpose of voting on such approval, and (b) by the
Trustees of the Trust or by a majority of the outstanding Units (as defined with
respect to voting securities in the 1940 Act) representing the interests in such
Portfolio; provided, however, that this Agreement may be terminated by the Trust
at any time, without the payment of any penalty, by vote of a majority of the
Trustees of the Trust or by vote of a majority of the outstanding Units (as so
defined) of the Trust on 60 days' written notice to Northern, or by Northern at
any time, without the payment of any penalty, on 60 days' written notice to the
Trust.

     12.  Amendment of Agreement. This Agreement may be amended by mutual
consent, but the consent of the Trust must be approved by vote of a majority of
those Trustees of the Trust who are not parties to this Agreement or interested
persons (as defined in the 1940 Act) of any such party.

     13.  Interpretative and Additional Provisions.  In connection with the
operation of this Agreement, Northern and the Trust may agree from time to time,
by written instrument signed by both parties, on such provisions interpretative
of or in addition to the provisions of this Agreement as may in their joint
opinion be consistent with the general tenor of this Agreement, provided that no
such interpretative or additional provisions shall contravene any applicable
Federal or State laws or regulations, or any provision of the Trust Agreement or
the Trust's By-laws, as the same may from time to time be amended. No
interpretative or additional provisions made as provided in the preceding
sentence shall be deemed to be an amendment of this Agreement.

     14.    Successor Custodian.

            (a)   Appointment of Successor by Trust. If a successor custodian is
                  appointed by the Trust

                                     -13-
<PAGE>
 
                   and a certified copy of the related appointing resolutions
                   are delivered to Northern, Northern shall, upon termination
                   of this Agreement or substitution of such successor for
                   Northern, deliver to such successor custodian at the office
                   of Northern, duly endorsed and in proper form for transfer,
                   all securities then held by Northern hereunder (or by any
                   agent or sub-custodian of Northern) and all funds or other
                   property of the Trust deposited with or held by Northern
                   hereunder (or by any agent or sub-custodian of Northern).

             (b)   Delivery Pursuant to Unitholder Resolution. In the event that
                   this Agreement is to be terminated but no new custodian can
                   be found by the Trust, the Trust shall, before authorizing
                   the delivery of such securities, funds and other property to
                   anyone other than a successor custodian, submit to its
                   Unitholders the question of whether the Trust shall be
                   liquidated or shall function without a custodian.  Upon
                   approval by the Unitholders for the Trust to liquidate or
                   function without a custodian Northern shall, in like manner
                   at its office, upon receipt of a certified copy of a
                   resolution of the Unitholders of the Trust deliver such
                   securities, funds and other property in accordance with such
                   resolution.

             (c)   Selection of Successor by Northern.  In the event that this
                   Agreement is terminated and no successor custodian has been
                   appointed by the Trust or certified copy of a resolution of
                   the Unitholders has been delivered to Northern on or before
                   the date when such termination shall become effective, then
                   Northern shall have the right to deliver to a bank or trust
                   company of its own selection, having an aggregate capital,
                   surplus, and undivided profits, as shown by its last
                   published report, of not less than $50 million, all
                   securities, funds, property and instruments of the Trust held
                   by Northern under this Agreement (or any agent or sub-
                   custodian of Northern) and all instruments held by Northern
                   (or such agent or sub-custodian) relative thereto.
                   Thereafter, such bank or trust company shall be the successor
                   custodian to Northern under this Agreement.

E.   Adjustment of Certain Fees Based on the Consumer Price Index
     ------------------------------------------------------------

     Effective April 30,1998 and effective each April 30 thereafter during the

<PAGE>
 
Northern shall have the right to permanently or temporarily waive all or any
portion of the Ie~ in any such Fee resulting from such adjustment. For purposes
of this

     (A) "Index" means the Consumer Price Index for All Urban Consumers, 1967 =
     100, published by the Bureau of Labor Statistics of the United States
     Department of Labor;

     (B) "Base Index Number" means the index number designated in the Index for
     "All Items" for the United States City Average for the month of December
     1982, which is acknowledged by the parties as being 292.4;

     (C) "Corresponding Index Number" with respect to a March 1 adjustment means
     the index number designated in the Index for "All Items" for the United
     States City Average for the month of December immediately preceding such
     March 1; and

     (D) If the publication of the index shall be discontinued so that the Fee
     applicable to a year commencing March 1 during the term of the Custodian
     Agreement cannot be computed in accordance with the foregoing provisions,
     then the Fee for such year shall be determined on the basis of comparable
     statistics reflecting changes in the urban cost of living in the United
     States, as computed and published by an agency of the United States or by a
     responsible financial periodical of recognized authority with such
     revisions in the method of computation provided for in this paragraph D as
     the circumstances may require in order to provide an inflation adjustment
     to such fee.

                   ADDENDUM NO. 5 TO THE CUSTODIAN AGREEMENT
                   -----------------------------------------

     This Addendum No. 5, dated as of the 1st day of December, 1997, is entered
into between THE BENCHMARK FUNDS (the "Trust"), a Massachusetts business trust,
and THE NORTHERN TRUST COMPANY, an Illinois state bank ("Northern").

     WHEREAS, the Trust and Northern have entered into a Custodian Agreement
(the "Agreement") dated June 8, 1992, as amended by Addendum No. 1 dated January
8, 1993, Addendum No. 2 dated July 1, 1993, Addendum No. 3 dated October 8, 1996
and Addendum No. 4 dated April 22, 1997 pursuant to which the Trust has
appointed Northern to act as custodian to the Trust for its Diversified Assets
Portfolio, Government Portfolio, Government Select Portfolio, Tax-Exempt
Portfolio, Equity Index Portfolio, Small Company Index Portfolio, Diversified
Growth Portfolio, Focused Growth Portfolio, U.S. Treasury Index Portfolio, U.S.
Government Securities Portfolio, Short-Intermediate Bond Portfolio, Bond
Portfolio, Balanced Portfolio and Intermediate Bond Portfolio (collectively, the
"Portfolios"); and

     WHEREAS, the Trust and Northern desire to enter into this Addendum No. 5 to
provide compensation for each Portfolio for uninvested cash balances maintained
with Northern under the Agreement;

     NOW THEREFORE, the parties hereto, intending to be legally bound, hereby
agree as follows:

          1.   Cash Balance Compensation.  Northern shall compensate each
               Portfolio for uninvested cash balances maintained with Northern
               at the end of each day ("Cash Balance Compensation") in
               accordance with this paragraph.  Cash Balance Compensation with
               respect to each Portfolio's uninvested cash balance shall be
               determined at the end of each day based on an annual rate equal
               to 96% of the previous calendar month's average 90-day Treasury
               bill interest rate.  The amount of each Portfolio's accumulated
               Cash Balance Compensation shall be paid monthly in the form of
               reductions to the custody fees otherwise allocable to the
               Portfolio under the Agreement for such month.  In the event that
               a Portfolio's Cash Balance Compensation for any month exceeds the
               custody fees payable by the Portfolio under the Agreement for
               such month, the Portfolio's excess Cash Balance Compensation may
               be carried forward and credited against future custody fees,
               provided that no excess Cash Balance Compensation may be carried
               forward beyond the end of any fiscal year.

          2.   Miscellaneous.  Except to the extent supplemented hereby, the
               Agreement shall remain unchanged and in full force and effect,
               and is hereby ratified and confirmed in all respects as
               supplemented hereby.

     IN WITNESS WHEREOF, the undersigned have executed this Addendum as of the
date and year first above written.

                              THE BENCHMARK FUNDS

                           FOREIGN CUSTODY AGREEMENT

     Agreement dated this 1st day of March 1994 between The Benchmark Funds, a
Massachusetts business trust (the "Trust"), and The Northern Trust Company, an
Illinois state bank ("Northern").

     1.  Appointment of Custodian.  The Trust hereby appoints Northern custodian
of all securities (including repurchase agreements), cash, cash equivalents and
other instruments (collectively, "Property") now owned or hereafter acquired by
the Trust on behalf of its International Growth Portfolio and International Bond
Portfolio, and any other investment portfolios of the Trust which may invest in
the securities of foreign issuers and which are specifically authorized by
resolution of the Trust's Board of Trustees to be added to this Agreement
(collectively, the "Portfolios"), and Northern hereby accepts such appointment,
upon the terms and conditions set forth in this Agreement. The Trust agrees
promptly to deliver and pay, or cause to be delivered and paid, to Northern, as
custodian for the Portfolios, or to an agent appointed pursuant to Section 8(a)
hereof or a sub-custodian appointed pursuant to Section 8(b) or 8(c) hereof, all
securities and cash now owned or hereafter acquired by the Trust on behalf of
the Portfolios.

     2.   Custody of Cash; Separate Accounts.
          ---------------------------------- 

          (a)  Accounts.  Northern will hold all cash and cash equivalents of
               each Portfolio, in a separate account or accounts in the name of
               such Portfolio, subject only to draft or order by Northern in
               accordance with the terms of this Agreement. If and when
               authorized by proper instructions of the Trustees or Officers of
               the Trust in accordance with a vote of the majority of the
               Trustees of the Trust, Northern may open and maintain an
               additional account or accounts in such other banks or trust
               companies as may be designated by such instructions, provided
               that such account or accounts shall be in the name of Northern in
               its capacity as custodian and subject only to its draft or order
               in accordance with the terms of this Agreement.

               It is understood that the Property in such account or accounts
               may be held in such countries or other jurisdictions as shall be
               specified from time to time in "proper instructions" (as defined
               in Section 9 hereof).

               (b)  Proceeds of Sale of Shares of Trust.  Upon receipt of funds
                    for the purchase of shares of any Portfolio, Northern shall
                    promptly deposit the purchase price in the account or
                    accounts maintained pursuant to Section 2(a) hereof.

               (c)  Collections.  Unless otherwise directed by proper
                    instructions from the Trustees or Officers of the Trust,
                    Northern shall collect, receive and deposit in the account
                    or accounts maintained pursuant to Section 2(a) hereof all
                    income, principal and other payments in respect of the
                    Property held by it under this Agreement and, subject to the
                    other provisions of this Agreement, do all other things
                    necessary or proper in connection with the collection of
                    such income, principal and other payments.  Without limiting
                    the generality of the foregoing, Northern shall:

                    (i)    present for payment by the date of payment all
                           coupons and other income items requiring
                           presentation;

                    (ii)   present for payment all securities which may mature
                           or be called, redeemed, retired or otherwise become
                           payable by the date such securities become payable;

                    (iii)  endorse and deposit for collection, on behalf of the
                           Trust, checks, drafts or other negotiable instruments
                           no later than the next business day as received;

                    (iv)   execute ownership and other certificates and
                           affidavits for all Federal and State tax purposes in
                           connection with the collection of income; and

                    (v)    notify the Trust as soon as reasonably practicable
                           whenever income, principal or other payments due on
                           securities are not collected in due course.

          In any case in which Northern does not receive any such due and unpaid
income, principal or other payment within a 

                                      -2-
<PAGE>
 
reasonable time after it has made proper demands for the same, it shall so
notify the Trust in writing, including copies of all demand letters, any written
responses thereto, and memoranda of telephonic demands and oral responses to
written and telephonic demands, and await proper instructions from the Trustees
or Officers of the Trust. Northern shall not be obliged to take legal action for
collection unless and until reasonably indemnified to its satisfaction.

          3.   Custody of Securities.
               --------------------- 

               (a)  Receipt of Securities.  Northern will hold in a separate
                    account, and physically segregated at all times from those
                    of any other persons, firms, corporations or other
                    Portfolios, pursuant to the provisions hereof, all
                    securities received by it for or for the account of a
                    Portfolio, subject to Sections 3(d), 8(a), 8(b) and 8(c)
                    hereof, which shall include securities the Portfolio desires
                    to be held in places within the United States ("domestic
                    securities") and "foreign securities," as defined in
                    paragraph (c)(1) of Rule 17f-5 ("Rule 17f-5") under the
                    Investment Company Act of 1940, as amended (hereinafter
                    collectively called "Securities").  All Securities shall be
                    held or disposed of by Northern for the Trust pursuant to
                    the terms of this Agreement.  Northern shall have no power
                    or authority to assign, hypothecate, pledge or otherwise
                    dispose of any such Securities, except pursuant to proper
                    instructions and only for the account of the Trust as set
                    forth in Section 5 hereof.  Any Securities delivered to
                    Northern other than in bearer form shall be properly
                    endorsed and in form for transfer or shall be in the name of
                    Northern, the Trust or a nominee of Northern or the Trust,
                    subject to Sections 3(d), 8(a), 8(b) and (c) hereof.

               (b)  Registered Name; Nominees.  Northern shall register
                    Securities of the Trust held by it under this Agreement,
                    other than those in bearer from, in the name of the Trust or
                    Northern or a nominee of the Trust or Northern.  Securities
                    held by an agent appointed pursuant to Section 8(a) hereof
                    or a sub-custodian appointed pursuant to Section 8(b) or
                    8(c) hereof may be registered in the name of such agent or
                    sub-custodian or a 

                                      -3-
<PAGE>
 
                    nominee of such agent or sub-custodian.

               (c)  Record Keeping and Inventory.  Northern shall maintain
                    records of all receipts, deliveries and locations of
                    Securities held by it under this Agreement, together with a
                    current inventory thereof.  Without limiting the generality
                    of the foregoing, Northern shall comply with such proper
                    instructions from the Trustees or Officers of the Trust as
                    may be issued from time to time in this regard.  With
                    respect to Securities held by any agent appointed pursuant
                    to Section 8(a) hereof or any sub-custodian appointed
                    pursuant to Section 8(b) or 8(c) hereof, Northern may rely
                    upon certificates of the agent or sub-custodian as to its
                    holdings, it being understood that such reliance in no way
                    relieves Northern of its responsibilities under this
                    Agreement.  Northern will promptly report to the Trust the
                    results of such inspections, indicating any shortages or
                    discrepancies uncovered thereby, and will take appropriate
                    action to remedy any such shortages or discrepancies.

               (d)  Use of Securities Depositories.  Northern, each agent
                    appointed pursuant to Section 8(a) hereof and each sub-
                    custodian appointed pursuant to Section 8(b) or 8(c) hereof
                    may deposit all or any part of the Securities held by it
                    hereunder and eligible therefor in the depository systems
                    covered by Rule 17f-4(b) under the 1940 Act; provided that
                    Northern, each such agent and each such sub-custodian shall
                    comply in all respects with clauses (d)(1) through (d)(4) of
                    Rule 17f-4 under the 1940 Act and, with respect to foreign
                    securities depositories, Rule 17f-5 under the 1940 Act; and
                    provided further, that no such deposit may be made prior to
                    the approval by the Trust of such depository system, which
                    approval may be subject to such conditions as the Trust may
                    from time to time determine; and provided further that with
                    respect to domestic depository systems, (1) all books and
                    records maintained by Northern and each such agent and sub-
                    custodian which relate to the Trust's participation in such
                    depository systems will at all times during regular business
                    hours be open to inspection by the Trust's duly authorized
                    officers, 

                                      -4-
<PAGE>
 
                    employees, agents and auditors, and the Trust will be
                    furnished with all the information in respect of the
                    services rendered to it as it may require, (2) in connection
                    with the use of such depository systems, Northern will
                    cooperate with the Trust in enforcing such rights as may
                    exist against such depository systems with respect to
                    transactions or Securities of a Portfolio, (3) payment for
                    Securities purchased for the account of any Portfolio shall
                    be made only upon (i) receipt of advice from the depository
                    system that such Securities have been transferred to the
                    account (the "Account") contemplated by clause (d)(2) of
                    Rule 17f-4 under the 1940 Act and (ii) the making of an
                    entry on the records of Northern or such agent or sub-
                    custodian, as the case may be, to reflect such payment and
                    transfer for the Account of such Portfolio, and (4) transfer
                    of Securities sold for the Account of any Portfolio shall be
                    made only upon (i) receipt of advice from the depository
                    system that payment for such Securities has been transferred
                    to the Account, and (ii) the making of an entry on the
                    records of Northern or such agent or sub-custodian, as the
                    case may be, to reflect such transfer and payment for the
                    Account of such Portfolio. Except as may otherwise be agreed
                    upon in writing by Northern and the Trust, Securities of a
                    Portfolio shall be maintained in foreign securities
                    depositories only through arrangements implemented by the
                    foreign banking institutions serving as sub-custodians
                    pursuant to Section 8(c) hereof.

                    maintained by Northern in the custody of a sub-custodian
                    pursuant to Section 8(b) or 8(c):  (1) Northern will
                    identify on its books as belonging to the particular
                    Portfolio any Property held by such sub-custodian; (2) any
                    Property held by a sub-custodian of Northern will be subject
                    only to the instructions of Northern or its agents, and any
                    Securities held in an eligible foreign securities depository
                    (as defined in Section 8(c)) for the account of a sub-
                    custodian will be subject only to the instructions of such
                    sub-custodian; (3) any agreement Northern shall enter into
                    with a 

                                      -5-
<PAGE>
 
                    foreign sub-custodian shall require that (i) the Property is
                    not subject to any right, charge, security interest, lien or
                    claim of any kind in favor of such sub-custodian or its
                    creditors except for a claim of payment for its safe custody
                    or administration and (ii) beneficial ownership of such
                    Property is freely transferable without the payment of money
                    or value other than for safe custody or administration;
                    provided, however, that the foregoing shall not apply to the
                    extent that any of the above-mentioned rights, charges, etc.
                    result from any compensation or other expenses arising with
                    respect to the safekeeping of Property pursuant to such
                    agreement; (4) Northern will supply to the Trust at least
                    monthly a statement in respect to any Property held by each
                    sub-custodian, including an identification of the entity
                    having possession of such Property, and Northern will send
                    to the Trust an advice or notification of any transfers of
                    Property indicating, as to Property acquired for a
                    Portfolio, the identity of the entity having physical
                    possession of such Property. In the absence of the filing in
                    writing with Northern by the Trust of exceptions or
                    objections to any such statement within sixty (60) days of
                    the Trust's receipt of such statement, or within sixty (60)
                    days after the date that a material defect is reasonably
                    discoverable, the Trust shall be deemed to have approved
                    such statement; and in such case or upon written approval of
                    the Trust of any such statement Northern shall, to the
                    extent permitted by law and provided Northern has used
                    reasonable care with respect to its obligations under this
                    Agreement, be released, relieved and discharged with respect
                    to all matters and things set forth in such statement as
                    though such statement has been settled by the decree of a
                    court of competent jurisdiction in an action in which the
                    Trust and all persons having any equity interest in the
                    Trust were parties; and (5) Northern hereby warrants to the
                    Trust that in its opinion, after due inquiry, the
                    established procedures to be followed by each of its
                    branches, each branch of a "qualified U.S. bank" and each
                    eligible "foreign custodian" (as defined in Section 8(c))
                    holding Property of the Trust pursuant to

                    this Agreement afford protection for such Property at least
                    equal to that afforded by Northern's established procedures

          8.   Appointment of Agents and Sub-Custodians.

               (a)  Appointment of Agents. Northern, as custodian, may at any
                    time or times appoint (and may at any time remove) in
                    accordance with the 1940 Act any other bank, trust company
                    or responsible commercial agent as its agent to carry out
                    such of the provisions of this Agreement as Northern may
                    from time to time direct, provided that the appointment of
                    such agent shall not relieve Northern of any of its
                    responsibilities under this Agreement.

               (b)  Appointment of Sub-Custodians Generally.

                    Northern, as custodian, may from time to time employ one or
                    more sub-custodians, but only in accordance with the terms
                    and conditions set forth in a resolution of the Trustees of
                    the Trust authorizing the appointment of each particular 
                    sub-custodian, it being understood and agreed that: (1)
                    Northern shall have no more responsibility or liability to
                    the Trust on account of any actions or omissions of any sub-
                    custodian so employed than such sub-custodian has to
                    Northern; (2) the responsibility or liability of the sub-
                    custodian to Northern shall conform to any resolution of the
                    Trustees of the Trust authorizing the appointment of the
                    particular sub-custodian or to the terms of any agreement
                    entered into between Northern and such sub-custodian to
                    which such resolution relates; provided, that Northern shall
                    not be responsible for the solvency of any sub-custodian
                    appointed by it with reasonable care; and (3) in no event
                    shall Northern be responsible for any act, omission, default
                    or for the solvency of any eligible foreign securities
                    depository approved by the Board of Trustees pursuant to
                    Section 3(d) hereof. Any determination of whether Northern
                    or a sub-custodian has exercised reasonable care under the
                    terms of any such agreement or otherwise shall be made in
                    light of prevailing standards applicable to professional
                    custodians in the jurisdiction in which such custodial
                    services are performed.

                    Northern shall be liable for the acts or omissions of a
                    foreign banking institution to

                                     -14-
<PAGE>
 

                    the same extent as set forth above with respect to sub-
                    custodians generally and, regardless of whether assets are
                    maintained in the custody of a foreign banking institution,
                    a foreign securities depository or a branch of Northern or
                    another U.S. bank, Northern shall not be liable for any
                    loss, damage, cost, expense, liability or claim resulting
                    from nationalization, expropriation, currency restrictions,
                    or acts of war or terrorism or any loss where the sub-
                    custodian has otherwise exercised reasonable care.

                    Northern may only deposit Securities in an account with a
                    sub-custodian which includes exclusively the assets held by
                    Northern for its customers, and Northern will cause such
                    account to be designated by such sub-custodian as a special
                    custody account for the exclusive benefit of customers of
                    Northern.

               (c)  Appointment of Foreign Sub-Custodians.

                    Northern may hold the Portfolios' foreign securities and
                    cash and cash equivalents in such amounts as Northern may
                    determine to be reasonably necessary to effect a Portfolio's
                    foreign securities transactions in accounts established by
                    Northern with one of its branches, a branch of a qualified
                    U.S. bank, an eligible foreign custodian or an eligible
                    foreign securities depository; provided, however, that the
                    Board of Trustees of the Trust has approved the use of such
                    eligible foreign custodian (and Northern's contract with
                    such custodian) or eligible foreign securities depository by
                    resolution, and proper instructions to such effect have been
                    provided to Northern. Furthermore, if a branch of Northern,
                    a branch of a qualified U.S. bank or an eligible foreign
                    custodian is selected to act as Northern's sub-custodian to
                    hold any Property, such entity is authorized to hold such in
                    its Account with any eligible foreign securities depository
                    in which it participates so long as such foreign securities
                    depository has been approved by the Board of Trustees of the
                    Trust. For purposes of this Agreement (1) "qualified U.S.
                    bank" shall mean a qualified U.S. bank as defined in Rule
                    17f-5 under the 1940 Act

                                     -15-
<PAGE>
 

                    ("Rule 17f-5"); (2) "eligible foreign custodian" shall mean
                    an eligible foreign custodian as defined in Rule 17f-5; and
                    (3) "eligible foreign securities depository" shall mean a
                    securities depository or clearing agency, incorporated or
                    organized under the laws of a country other than the United
                    States, which operates (i) the central system for handling
                    of securities or equivalent book-entries in that country or
                    (ii) a transnational system for the central handling of
                    securities or equivalent book-entries, or is otherwise
                    authorized by the Securities and Exchange Commission to hold
                    the portfolio securities of registered investment companies.

          For purposes of this Section 8(c), the term "sub-custodian" will refer
to (i) any branch of Northern, (ii) any branch of a qualified U.S. bank or any
eligible foreign custodian with which Northern has entered into an agreement of
the type contemplated hereunder or (iii) any eligible foreign securities
depository.

          If, after the initial approval of the sub-custodians by the Board of
Trustees of the Trust in connection with this Agreement, Northern wishes to
appoint other sub-custodians to hold Property of the Portfolios, it will so
notify the Trust and will provide it with information reasonably necessary to
determine any such new sub-custodian's eligibility under Rule 17f-5, including a
copy of the proposed agreement with such sub-custodian. The Trust shall within
30 days after receipt of such notice give a written approval or disapproval of
the proposed action.

          If Northern intends to remove any sub-custodian previously approved,
it shall so notify the Trust and shall move the Property deposited with such 
sub-custodian to another sub-custodian previously approved or to a new sub-
custodian, provided that the appointment of any new sub-custodian will be
subject to the requirements set forth in the preceding paragraph. Northern shall
take steps as may be required to remove any sub-custodian which has ceased to
meet the requirements of Rule 17f-5.

          Northern shall provide to the Trust on at least an annual basis, a
report confirming that its arrangements hereunder with respect to foreign sub-
custodians remain in compliance with the rules of the Securities and Exchange
Commission governing such arrangements.

          9.   Proper Instructions.

               (a)  Proper Instructions Generally. Proper instructions shall be
                    deemed to have been issued upon issuance of written
                    instructions signed by not less than one officer and one
                    responsible employee of Northern which in the case of each
                    such officer and employee Northern's Board of Directors
                    shall have from time to time authorized to give the
                    particular class of instructions in question. Different
                    persons may be authorized to give instructions for different
                    purposes.

               (b)  Proper Instructions from the Trustees or Officers of the
                    Trust. Proper instructions from the Trustees or Officers of
                    the Trust shall be deemed to have been issued upon receipt
                    by Northern of written instructions (including receipt of
                    facsimile) signed by a majority of the Trustees of the Trust
                    or by not less than two of the Officers or Trustees of the
                    Trust designated from time to time by resolution of the
                    Trustees. Such instructions shall be deemed proper
                    instructions as that term is used in this Agreement in
                    addition to also being deemed proper instructions from the
                    Trustees or Officers of the Trust. A certificate executed by
                    the Secretary or Assistant Secretary of the Trust as to the
                    persons serving as Trustees and/or who are Officers of the
                    Trust designated as set forth above may be received and
                    accepted by Northern as conclusive evidence of those persons
                    who are such Trustees and/or Officers and may be considered
                    to be accurate until receipt of written notice (or oral
                    notice followed by written confirmation within seven days)
                    to the contrary. In the case of conflict between
                    instructions under Section 9(a) and under this Section 9(b),
                    those given pursuant to this Section 9(b) shall prevail upon
                    receipt by Northern.

          10. Delivery of Documents. The Trust has furnished Northern with
copies, properly certified or authenticated, of the following: before any
Portfolio engages in any transactions regulated by the Commodity Futures Trading
Commission ("CFTC"), a copy of either (i) a filed notice of eligibility to claim
the exclusion from the definition of "commodity pool operator" contained in
Section 2(a)(1)(A) of the Commodity Exchange Act

                                     -17-

("CEA") that is provided in Rule 4.5 under the CEA, together with all
supplements as are required by the CFTC, or (ii) a letter which has been granted
the Trust by the CFTC which states that the Trust will not be treated as a
"pool" as defined in Section 4.10(d) of the CFTC's General Regulations, or (iii)
a letter which has been granted the Trust by the CFTC which states that the CFTC
will not take any enforcement action if the Trust does not register as a
"commodity pool operator."

          The Trust will furnish Northern from time to time with copies,
properly certified or authenticated, of all amendments of or supplements to the
foregoing, if any.

          11.  Segregated Accounts.

                    (a) Northern shall upon receipt of proper instructions
               establish and maintain a segregated account or accounts on its
               records for and on behalf of each Portfolio of the Trust, into
               which account or accounts may be transferred cash and/or
               Securities, including securities in a depository system (i) for
               the purposes of compliance by the Trust with the procedures
               required by a securities or option exchange, providing such
               procedures comply with the 1940 Act and Release No. 10666 or any
               subsequent release or releases of the Securities and Exchange
               Commission ("SEC") relating to the maintenance of segregated
               accounts by registered investment companies, and (ii) for other
               proper corporate purposes, but only, in the case of clause (ii),
               upon receipt of proper instructions.

                    (b) Northern may enter into separate procedural, safekeeping
               or other agreements with various futures commission merchants
               ("FCMs") and banks that are unaffiliated with the Trust (each a
               "Safekeeping Arrangement"), pursuant to which the banks will act
               as the Trust's custodian with respect to the Trust's margin
               deposits in transactions involving futures contracts and options
               on futures contracts. Such margin deposits will be held in
               segregated accounts (each an "FCM Account") subject to the
               disposition by the FCM involved in accordance with the customer
               contract between FCM and the Trust ("FCM Contract"), SEC rules
               governing such segregated accounts, CFTC rules and the rules of
               the applicable commodities exchange. Transfers of initial and
               variation margin and premiums shall be made from the Trust's
               custodial accounts under the Custodian Agreement upon proper
               instructions.

custodian, the compensation and expense reimbursement set forth in Exhibit A
hereto.

          13. Duration and Termination. This Agreement shall continue, unless
sooner terminated as provided herein, until February 29, 1996, and for each
Portfolio thereafter shall continue automatically for periods of one year so
long as each such latter continuance is approved at least annually (a) by the
vote of a majority of the Trustees of the Trust who are not parties to this
Agreement or interested persons (as defined by the 1940 Act) of any such party,
cast in person at a meeting called for the purpose of voting on such approval,
and (b) by the Trustees of the Trust or by a majority of the outstanding Shares
(as defined with respect to voting securities in the 1940 Act) representing the
interests in such Portfolio; provided, however, that this Agreement may be
terminated by the Trust at any time, without the payment of any penalty, by vote
of a majority of the Trustees of the Trust or by vote of a majority of the
outstanding Shares (as so defined) of the Trust on 60 days' written notice to
Northern, or by Northern at any time, without the payment of any penalty, on 60
days' written notice to the Trust.

          14. Amendment of Agreement. This Agreement may be amended by mutual
consent, but the consent of the Trust must be approved by vote of a majority of
those Trustees of the Trust who are not parties to this Agreement or interested
persons (as defined in the 1940 Act) of any such party.

          15. Interpretative and Additional Provisions. In connection with the
operation of this Agreement, Northern and the Trust may agree from time to time,
by written instrument signed by both parties, on such provisions interpretative
of or in addition to the provisions of this Agreement as may in their joint
opinion be consistent with the general tenor of this Agreement, provided that no
such interpretative or additional provisions shall contravene any applicable
Federal or State laws or regulations, or any provision of the Trust Agreement or
the Trust's By-laws, as the same may from time to time be amended. No
interpretative or additional provisions made as provided in the preceding
sentence shall be deemed to be an amendment of this Agreement.

          16.  Successor Custodian.

               (a)  Appointment of Successor by Trust. If a successor custodian
                    is appointed by the Trust and a certified copy of the
                    related appointing resolutions is delivered to Northern,
                    Northern shall, upon termination of this Agreement or
                    substitution of such

                                     -19-
<PAGE>
 

                    successor for Northern, deliver to such successor custodian,
                    duly endorsed and in proper form for transfer, all
                    Securities then held by Northern hereunder (or by any agent
                    or sub-custodian of Northern) and all funds or other
                    Property of the Trust deposited with or held by Northern
                    hereunder (or by any agent or sub-custodian of Northern).

               (b)  Delivery Pursuant to Shareholder Resolution. In the event
                    that this Agreement is to be terminated but no new custodian
                    can be found by the Trust, the Trust shall, before
                    authorizing the delivery of the Securities, funds and other
                    Property to anyone other than a successor custodian, submit
                    to its Shareholders the question of whether the Trust shall
                    be liquidated or shall function without a custodian. Upon
                    approval by the Shareholders for the Trust to liquidate or
                    function without a custodian Northern shall, in like manner,
                    upon receipt of a certified copy of a resolution of the
                    Shareholders of the Trust deliver such Securities, funds and
                    other Property in accordance with such resolution.

               (c)  Selection of Successor by Northern. In the event that this
                    Agreement is terminated and no successor custodian has been
                    appointed by the Trust or certified copy of a resolution of
                    the Shareholders has been delivered to Northern on or before
                    the date when such termination shall become effective, then
                    Northern shall have the right to deliver to a bank or trust
                    company of its own selection, having an aggregate capital,
                    surplus, and undivided profits, as shown by its last
                    published report, of not less than $200 million, all
                    Securities, funds, property and instruments of the Trust
                    held by Northern under this Agreement (or any agent or sub-
                    custodian of Northern) and all instruments held by Northern
                    (or such agent or sub-custodian) relative thereto.
                    Thereafter, such bank or trust company shall be the
                    successor custodian to Northern under this Agreement.

                              THE BENCHMARK FUNDS

                ADDENDUM NO. 2 TO THE FOREIGN CUSTODY AGREEMENT


     This Addendum No. 2, dated as of the 27th day of January, 1998, is entered
into between THE BENCHMARK FUNDS (the "Trust"), a Massachusetts business trust,
and THE NORTHERN TRUST COMPANY, an Illinois state bank ("Northern").

     WHEREAS, the Trust and Northern have entered into a Foreign Custody
Agreement dated March 1, 1994 (the "Agreement"), pursuant to which the Trust has
appointed Northern to act as custodian to the Trust for its International Growth
Portfolio, International Bond Portfolio and International Equity Index Portfolio
(collectively, the "Portfolios"); and

     WHEREAS, the Trust and Northern desire to enter into this Addendum No. 2 to
provide compensation for each Portfolio for uninvested cash balances maintained
with Northern under the Agreement;

     NOW THEREFORE, the parties hereto, intending to be legally bound, hereby
agree as follows:

          1.   Cash Balance Compensation. Northern shall compensate each
               Portfolio for uninvested cash balances maintained with Northern
               at the end of each day ("Cash Balance Compensation") in
               accordance with this paragraph. Cash Balance Compensation with
               respect to each Portfolio's uninvested cash balance shall be
               determined at the end of each day based on an annual rate equal
               to 96% of the previous calendar month's average 90-day Treasury
               bill interest rate. The amount of each Portfolio's accumulated
               Cash Balance Compensation shall be paid monthly in the form of
               reductions to the custody fees otherwise allocable to the
               Portfolio under the Agreement for such month. In the event that a
               Portfolio's Cash Balance Compensation for any month exceeds the
               custody fees payable by the Portfolio under the Agreement for
               such month, the Portfolio's excess Cash Balance Compensation may
               be carried forward and credited against future custody fees,
               provided that no excess Cash Balance Compensation may be carried
               forward beyond the end of any fiscal year.

          2.   Miscellaneous. Except to the extent supplemented hereby, the
               Agreement shall remain unchanged and in full force and effect,
               and is hereby ratified and confirmed in all respects as
               supplemented hereby.

                     FOREIGN CUSTODY MONITORING AGREEMENT



     AGREEMENT made as of January 27, 1998 between THE BENCHMARK FUNDS, a
Massachusetts business trust (the "Trust"), and THE NORTHERN TRUST COMPANY, an
Illinois state bank ("Northern").

     WHEREAS, the Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940 Act");

     WHEREAS, the Trust has retained Northern to furnish investment advisory,
custodial and other services;

     WHEREAS, the Board of Trustees of the Trust wishes to delegate to Northern
the responsibility of monitoring the Trust's foreign custody arrangements as
provided in Rule 17f-5 under the 1940 Act, and Northern is willing to undertake
such responsibility;

     WHEREAS, the Board of Trustees of the Trust has determined that it is
reasonable to rely on Northern to perform the responsibilities delegated to it
under this Agreement;

     NOW, THEREFORE, in consideration of the mutual covenants herein contained,
and intending to be legally bound, the parties hereto agree as follows:

     1.   The Trust hereby delegates to Northern the responsibility of
monitoring foreign custody arrangements for the Trust's existing and future
investment portfolios in accordance with Rule 17f-5 under the 1940 Act, and
Northern accepts such delegation and agrees to furnish the services set forth
herein.

     2.   With respect to each foreign sub-custodian that holds assets of any
investment portfolio of the Trust, Northern shall:

          (a) determine that the Trust's assets will be subject to reasonable
          care, based on the standards applicable to custodians in the relevant
          market, if maintained with such foreign sub-custodian, after
          considering all factors relevant to the safekeeping of such assets,
          including, without limitation:

               (i) the foreign sub-custodian's practices, procedures and
               internal controls, including but not limited to, the physical
               protections available for certificated securities (if
               applicable), the method of keeping custodial records and the
               security and data protection practices;

               (ii) whether the foreign sub-custodian has the requisite
               financial strength to provide reasonable care for the Trust's
               assets;

               (iii) the foreign sub-custodian's general reputation and standing
               and, in the case of a foreign securities depository, the
               depository's operating history and number of participants; and

               (iv) whether the Trust will have jurisdiction over and be able to
               enforce judgments against the foreign sub-custodian, such as by
               virtue of the existence of any offices of the foreign sub-
               custodian in the United States or the foreign sub-custodian's
               consent to service of process in the United States.
<PAGE>
 
          (b) determine that the written contract with such foreign sub-
          custodian governing the foreign custody arrangements (or, in the case
          of a foreign securities depository, that a written contract, the rules
          or established practices or procedures of the depository or any
          combination of the foregoing) will provide reasonable care for the
          Trust's assets based on the standards specified in paragraph 2(a)
          above, and that such contract includes provisions that at least
          provide the following; provided, however, that such contract may
          contain, in lieu of any or all of the provisions specified in (b)(i)
          through (b)(v), such other provisions that Northern determines will
          provide, in their entirety, the same or a greater level of care and
          protection for the Trust's assets as those provided in (b)(i) through
          (b)(v) in their entirety:
          
               (i) for indemnification or insurance arrangements (or any
               combination of the foregoing) such that the Trust will be
               adequately protected against the risk of loss of assets held in
               accordance with such contract;

               (ii) that the Trust's assets will not be subject to any right,
               charge, security interest, lien or claim of any kind in favor of
               the foreign sub-custodian or its creditors except a claim of
               payment for their safe custody or administration or, in the case
               of cash deposits, liens or rights in favor of creditors of the
               sub-custodian arising under bankruptcy, insolvency, or similar
               laws;

               (iii) that beneficial ownership for the Trust's assets will be
               freely transferable without the payment of money or value other
               than for safe custody or administration;

               (iv) that adequate records will be maintained identifying the
               assets as belonging to the Trust or as being held by a third
               party for the benefit of the Trust and that the Trust's
               independent public accountants will be given access to those
               records or confirmation of the contents of those records; and

               (v) that the Trust will receive periodic reports with respect to
               the safekeeping of the Trust's assets, including, but not limited
               to, notification of any transfer to or from the Trust's account
               or a third party account containing assets held for the benefit
               of the Trust.

          (c) establish a system to monitor the appropriateness of maintaining
          the Trust's assets with such foreign sub-custodian and the contract
          governing the Trust's foreign custody arrangements;

          (d) provide to the Trust's Board of Trustees, at least annually,
          written reports notifying the Board of the placement of the Trust's
          assets with a particular foreign sub-custodian and quarterly reports
          on any material changes to the Trust's foreign custody arrangements;
          and

          (e) withdraw the Trust's assets from any foreign sub-custodian as soon
          as reasonably practicable, if the foreign custody arrangement no
          longer meets the requirement of Rule 17f-5.

     3.   In providing the services set forth above, Northern agrees to exercise
reasonable care, prudence and diligence such as a person having responsibility
for the safekeeping of the Trust's assets would exercise.

                     AGREEMENT AND PLAN OF REORGANIZATION
                     ------------------------------------


          THIS AGREEMENT AND PLAN OF REORGANIZATION made this 15th day of
August, 1990, by and between The Benchmark Tax-Exempt Fund (the "Trust"), a
Massachusetts business trust established under an Agreement and Declaration of
Trust dated July 15, 1982, as amended, on behalf of the Short-Term Diversified
Portfolio, a series of the Trust (the "Trust Portfolio"), and The Benchmark
Money Market Fund Diversified Assets and Government Portfolios ("TBF"), a
Massachusetts business trust established under an Agreement and Declaration of
Trust dated July 15, 1982, as amended, on behalf of the Tax-Exempt Portfolio, a
Portfolio of TBF (the "TEP").

          WHEREAS, the Trust and TBF are diversified, open-end registered
investment companies of the management type; and

          WHEREAS, the Trust and TBF are authorized to issue their units of
beneficial interest in separate series, each of which maintains a separate and
distinct portfolio of assets;

          WHEREAS, the Trust Portfolio is one series of the Trust and the TEP is
one Portfolio of TBF;

          WHEREAS, the Trust Portfolio owns securities which are assets of the
character in which the TEP is permitted to invest;

          WHEREAS, the Board of Trustees of the Trust and TBF have determined
that the transfer of all of the assets and liabilities of the Trust Portfolio to
the TEP is in the best interest of the Trust and TBF because it would provide
more efficient management and administration of those assets and that the
interests of the existing unitholders of the Trust and TBF would not be diluted
as a result of this transaction;

          WHEREAS, the parties hereto intend to provide for the reorganization
of the Trust Portfolio through the acquisition by the TEP of all of the assets,
subject to all of the liabilities, of the Trust Portfolio in exchange for units
of beneficial interest, no par value, of the TEP (the "TEP Units"), the
termination of the Trust Portfolio and the distribution to its unitholders of
such TEP Units, all pursuant to the provisions of Section 368(a)(1)(F) of the
Internal Revenue Code of 1986, as amended (the "Code");

          NOW THEREFORE, in consideration of the mutual promises herein
contained, the parties hereto agree as follows:
<PAGE>
 
          1.   Plan of Reorganization and Liquidation.

               (a)  The Trust, on behalf of the Trust Portfolio, shall assign,
sell, convey, transfer and deliver to the TEP at the closing provided for in
Section 2 (hereinafter called the "Closing") all of the then existing assets of
the Trust Portfolio of every kind and nature. In consideration therefor, the TEP
shall at the Closing (i) assume all of the Trust Portfolio's obligations and
liabilities then existing, whether absolute, accrued, contingent or otherwise,
including without limitation all fees and expenses in connection with the
transactions contemplated hereby and (ii) deliver to the Trust Portfolio a
number of full and fractional TEP Units equal to the number of full and
fractional units of the Trust Portfolio then outstanding. The number of units of
the Trust Portfolio issued and outstanding and the number of TEP Units to be
issued to the Trust Portfolio shall in each case be determined by the Custodian
to both the Trust and TBF as of 3:30 p.m., Chicago time, on the Closing Date (as
defined in Section 2). The determination of said Custodian shall be conclusive
and binding on the Trust Portfolio, the TEP and their respective unitholders.

               (b)  Upon consummation of the transactions described in paragraph
(a) of this Section 1, the Trust Portfolio shall distribute in complete
liquidation pro rata to its unitholders of record as of the Closing Date the TEP
Units received by the Trust Portfolio. Such distribution shall be accomplished
by the establishment of an open account on the unit records of the TEP in the
name of each unitholder of the Trust Portfolio representing a number of TEP
Units equal to the number of units of the Trust Portfolio owned of record by the
unitholder at the Closing Date. Certificates for units of the Trust Portfolio
issued prior to the reorganization, if any, shall represent outstanding units of
the TEP following the reorganization. In the interest of economy and
convenience, certificates representing the TEP will not be physically issued.

               (c)  As promptly as practicable after the Closing Date, the Trust
Portfolio and the Trust shall be terminated pursuant to the provisions of the
laws of the Commonwealth of Massachusetts and the Trust's Agreement and
Declaration of Trust and an application prepared, executed and filed with the
Securities and Exchange Commission (the "SEC") seeking, and the Trust shall use
its best efforts to obtain, an SEC order declaring that the Trust has ceased to
be a registered investment company. After the Closing Date, the Trust shall not
conduct any business except in connection with its liquidation, termination and
deregistration.

          2.  Closing and Closing Date. The Closing shall occur at the offices
of the Distributor at 3:30 p.m., Chicago time, on

                                      -2-
<PAGE>
 
October 5, 1990 or at such later time and date, or at such other location, as
the parties may mutually agree (the "Closing Date"). All acts taking place at
the Closing shall be deemed to take place simultaneously on the Closing Date
unless otherwise provided.

          3.   Conditions Precedent. The obligation of the Trust and TBF to
effect the transactions contemplated hereunder shall be subject to the
satisfaction of each of the following conditions:

               (a)  All filings shall have been made with, and all authority and
orders shall have been received from, the SEC and state securities commissions
as may be necessary in the opinion of Drinker Biddle & Reath to permit the
parties to carry out the transactions contemplated by this Agreement.

               (b)  The Trust and TBF shall have received an opinion of Drinker
Biddle & Reath substantially to the effect that for federal income tax purposes:
(i) the acquisition of the assets and assumption of the liabilities of the Trust
Portfolio by the TEP in return for TEP Units followed by the distribution of
such units to Trust Portfolio unitholders will constitute a "reorganization"
within the meaning of Section 368(a)(1)(F) of the Code and the TEP and the Trust
Portfolio will each be "a party to the reorganization" within the meaning of
Section 368(b) of the Code; (ii) no gain or loss will be recognized by the Trust
Portfolio upon the transfer of its assets and liabilities to the TEP; (iii) the
tax basis of the assets of the Trust Portfolio in the hands of the TEP will be
the same as the tax basis of such assets in the hands of the Trust Portfolio
immediately prior to the transfer; (iv) the TEP's holding period for the assets
of the Trust Portfolio transferred to TEP will include the period during which
such assets were held by the Trust Portfolio; (v) no gain or loss will be
recognized by the TEP upon the receipt of the assets of the Trust Portfolio in
exchange for TEP Units and the assumption by the TEP of the liabilities of the
Trust Portfolio; (vi) no gain or loss will be recognized by the unitholders of
the Trust Portfolio upon the receipt of TEP units in exchange for their units in
the Trust Portfolio; (vii) the basis of the TEP Units received by the
unitholders of the Trust Portfolio will be the same as the basis of the units of
the Trust Portfolio exchanged therefor; and (viii) the holding period of the TEP
Units received by the unitholders of the Trust Portfolio will include the
holding period of the units of the Trust Portfolio exchanged therefor, provided
that at the time of the exchange the units of the Trust Portfolio were held as
capital assets; and as to such other matters as they may reasonably request;

               (c)  This Agreement and Plan of Reorganization and the
reorganization contemplated hereby shall have been approved

                                      -3-
<PAGE>
 
by the Board of Trustees of the Trust and of TBF and shall have been recommended
for approval to the unitholders of the Trust Portfolio by the Trust's Board of
Trustees;

               (d)  This Agreement and Plan of Reorganization and the
reorganization contemplated hereby shall have been approved by the affirmative
vote of the holders of a majority of the outstanding units of beneficial
interest of the Trust Portfolio (as defined in the Trust's Agreement and
Declaration of Trust) entitled to vote thereon;

               (e)  TBF on behalf of the TEP shall have entered into an
Investment Advisory Agreement with The Northern Trust Company, such Agreement to
be substantially identical in form and substance as to the TEP to the Investment
Advisory Agreement in effect at the Closing Date between the Trust and said
other party, and such Agreement shall have been approved by the Trustees of TBF
and, to the extent required by law, by the Trustees of TBF who are not
"interested persons" of TBF as defined in the Investment Company Act of 1940
(the "1940 Act") as well as by the unitholders of the TEP (it being understood
that the Trust, as sole unitholder of the TEP prior to the consummation of the
reorganization, hereby agrees and is authorized to vote for such approval); and

               (f)  The Trustees of TBF who are not "interested persons" of TBF
as defined in the 1940 Act shall have selected as auditors for TBF such auditors
as shall have been selected and ratified for the Trust and such selection shall
have been ratified by the unitholders of TEP (it being understood that the
Trust, as sole unitholder of the TEP prior to the consummation of the
reorganization, hereby agrees and is authorized to vote for such ratification).

               (g)  The Trust agrees to file with the SEC proxy materials (the

          4. Affiliates and Correspondent Banks. It is understood that Units of
the Money Market Portfolios may be offered to customers of affiliates or
correspondent banks of Northern, that such banks may maintain omnibus accounts
at Northern and that, in such event, such affiliates or correspondent banks may
perform for Northern some or all of the services which Northern has undertaken
to perform under this Agreement. It also is understood that Northern may retain
Goldman, Sachs & Co. to determine, based on information provided by Northern,
the amounts in the accounts of Northern's demand deposit account customers that
are to be automatically invested in Units and to maintain certain subaccounting
records with respect thereto. Notwithstanding the fact that such services may
actually be performed by such affiliates, correspondent banks or Goldman, Sachs
& Co.:

             a. Northern shall remain responsible on a primary basis to the
Trust for the timely and proper performance of such services in accordance with
the terms of this Agreement and for compliance with all provisions of, and the
accuracy of all representations and warranties contained in, this Agreement
which, as to such services, would be applicable to such affiliates,
correspondent banks or Goldman, Sachs & Co. if they were included within the
term "Northern" hereunder.

             b. For purposes of administering (including giving Instructions and
notices and making requests and fee payments) and enforcing this Agreement, the
Trust shall be entitled (but not obligated) to deal solely with Northern.

             c. To the extent that a correspondent bank shall perform for
Northern services which Northern has undertaken to perform hereunder, Northern
shall enter into a written agreement with such correspondent bank. Such
agreement shall provide, among other things, for: (i) accurate reporting by
means of a certificate of the number of subaccounts for which a fee is due and
(ii) the right on the part of the Trust to recover any excess payments. Northern
shall be entitled to rely on the accuracy of such certificates, provided that
its reliance is reasonable.

          5. Expenses. During the term of this Agreement, Northern will pay all
expenses incurred by it in connection with the performance of its duties under
this Agreement.

          6. Compensation With Respect to Money Market Portfolios.

pursuant to this Agreement with respect to

                                      -7-
<PAGE>
 

the Money Market Portfolios, the Trust will pay to Northern as full compensation
therefor a fee at the rate of $18.00 per annum for each Unitholder subaccount
that is either (i) maintained by Northern or its affiliates or (ii) maintained
by a correspondent bank of Northern and as to which Northern pays such
correspondent $18.00 per annum. Such fee shall be computed and paid monthly. The
fee with respect to a given month shall be computed by multiplying one-twelfth
of the annual fee by the number of such subaccounts as to which a purchase or
redemption of Units transaction occurred during, or which contained a Unit
balance at the end of, such month.

             b. Effective April 30, 1993 and effective each April 30 thereafter
during the term of this Agreement the fee of $18.00 per annum referred to in
paragraph (a) above shall be adjusted by multiplying such fee by a fraction the
denominator of which is the Base Index Number and the numerator of which is the
Corresponding Index Number; provided, however that (i) in no event shall such
fee be less than $18.00 per annum and (ii) Northern shall have the right to
permanently or temporarily waive all or any portion of the increase in its fee
resulting from such adjustment. For purposes of this paragraph (b):

             (A) "Index" means the Consumer Price Index for All Urban Consumers,
             1967 = 100, published by the Bureau of Labor Statistics of the
             United States Department of Labor;

             (B) "Base Index Number" means the index number designated in the
             Index for "All Items" for the United States City Average for the
             month of December, 1982, which is acknowledged by the parties as
             being 292.4;

             (C) "Corresponding Index Number" with respect to a March 1
             adjustment means the index number designated in the Index for "All
             Items" for the United States City Average for the month of December
             immediately preceding such March 1; and

             (D) If the publication of the Index shall be discontinued so that
             the fee applicable to a year commencing March 1 during the term of
             this Agreement cannot be computed in accordance with the foregoing
             provisions, then the fee for such year shall be determined on the
             basis of comparable statistics reflecting changes in the urban cost
             of living in the United States, as computed and published by an
             agency of the United States or by a responsible financial
             periodical of recognized authority with such revisions in the
             method of computation provided for in this

                                      -8-

             paragraph (b) as the circumstances may require in order to provide
             an inflation adjustment to such fee.

          7. Compensation With Respect to Non-Money Market Portfolios. For the
services provided and the expenses assumed by Northern pursuant to this
Agreement with respect to the Non-Money Market Portfolios, the Trust will pay to
Northern as full compensation therefore a fee payable monthly at an annual rate
of .01%, .05%, .10% and .15% of the average daily net asset value of each
Portfolio's Class A, B, C and D Units, respectively.

          8. Duration and Termination. Insofar as the holders of Units
representing the interests in the Series known as the Current Portfolios are
affected by this Agreement, it shall continue, unless sooner terminated as
provided herein, until April 30, 1994, and, insofar as the holders of Units
representing the interests in each of the other Series are affected by this
Agreement, it shall continue until April 30 of the year following the year in
which the Series commences investment operations, and as to each Series
thereafter shall continue automatically for periods of one year so long as each
such latter continuance is approved at least annually (a) by the vote of a
majority of the Trustees of the Trust who are not parties to this Agreement or
interested persons (as defined by the 1940 Act) of any such party, cast in
person at a meeting called for the purpose of voting on such approval, and (b)
by the Trustees of the Trust; provided, however, that this Agreement may be
terminated by the Trust at any time with respect to any Class of Units, without
the payment of any penalty, by vote of a majority of the Trustees of the Trust
or by vote of a majority of the outstanding Units (as so defined) of such Class
on 60 days' written notice to Northern, or by Northern at any time, without the
payment of any penalty, on 60 days' written notice to the Trust. This Agreement
will automatically and immediately terminate in the event of its assignment (as
defined by the 1940 Act).

          9. Amendment of Agreement. This Agreement may be amended by mutual
consent, but the consent of the Trust must be approved by vote of a majority of
those Trustees of the Trust who are not parties to this Agreement or interested
persons (as defined in the 1940 Act) of any such party.

          10. Interpretative and Additional Provisions. In connection with the
operation of this Agreement, Northern and the Trust may agree from time to time,
by written Instrument signed by both parties, on such provisions interpretative
of or in addition to the provisions of this Agreement as may in their joint
opinion be consistent with the general tenor of this Agreement, provided that no
such interpretative or additional provisions shall contravene any applicable
Federal or State laws or regulations, or any provision of the Trust's Agreement
and

                                      -9-
<PAGE>
 

Declaration of Trust or By-laws, as the same may from time to time be amended.
No interpretative or additional provisions made as provided in the preceding
sentence shall be deemed to be an amendment of this Agreement.

          11. Instructions.
       
             a. Northern shall be deemed to have received Instructions (as that
term is used herein) upon receipt of written instructions (including receipt by
facsimile), which may be continuing instructions, signed by not less than two of
the persons the Trustees shall have from time to time authorized to give the
particular class of Instructions in question. Different persons may be
authorized to give Instructions for different purposes, and Instructions may be
general or specific in terms. A certified copy of a by-law, resolution or action
of the Trustees of the Trust may be received and accepted by Northern as
conclusive evidence of the authority of any such persons to act and may be
considered to be in full force and effect until receipt of written notice (or
oral notice followed by written confirmation within seven days) to the contrary.

             b. One or more designated persons may be authorized to issue oral
(such term as used herein including, without limitation, telephoned)
instructions, specifying the type or types of instructions that may be so
issued, in which case the Trust shall deliver to Northern resolutions of the
Trustees to such effect. Two or more of the persons designated by the Trustees
to give oral instructions shall promptly confirm such oral instructions in
writing to Northern. Such instructions when given in accordance with the
provisions hereof and with such resolutions shall be deemed Instructions
hereunder. In the case of conflict between oral Instructions given by a person
designated in the resolution of the Trustees referred to in the first sentence
of this subparagraph (b) and any written Instructions, the Instructions most
recently received by Northern shall prevail following such receipt, and in case
of conflict between oral Instructions given by a person designated in such
resolution and any written confirmation or purported confirmation of oral
Instructions, such written confirmation or purported confirmation shall prevail
following receipt thereof by Northern; provided that any transaction initiated
by Northern pursuant to such oral Instructions, may, but need not, be completed
by Northern notwithstanding Northern's receipt of conflicting subsequent
Instructions hereunder or written confirmation or purported confirmation of oral
Instructions hereunder subsequent to Northern's initiation of such transaction.

          12. Audit, Inspection and Visitation. In addition to its other duties
hereunder, Northern shall cooperate with the Trust and the Trust's independent
public accountants in connection with (a) the preparation of reports to the

Unitholders, to the Securities and Exchange Commission (the "Commission")
(including all required periodic and other reports), to state securities
commissioners and to others, (b) annual and other audits of the books and
records of the Trust, and (c) other matters of a like nature. Northern shall
make available during regular business hours all records and other data created
and maintained pursuant to this Agreement for reasonable audit, inspection and
copying by the Trust, its Administrator, the Trust's independent public
accountants, or any other person retained by the Trust or its Administrator, or
by agents of the Commission. Upon reasonable notice by the Trust or its
Administrator, Northern shall make available during regular business hours its
facilities and premises employed in connection with its performance of this
Agreement for reasonable visitation by any of the persons referred to in the
preceding sentence.

          13. Opinion and Reports of Trust's Independent Accountants.

             a. Northern shall take all reasonable action, as the Trust may from
time to time request, to obtain from year to year favorable opinions from the
Trust's independent accountants in connection with the preparation of the
Trust's Form N-1A and Form N-SAR or other reports to the Commission and with
respect to any other requirements of the Commission.

             b. Northern shall provide the Trust or its Administrator, at such
times as the Trust or its Administrator may reasonably require, with reports by
independent public accountants on the accounting system and internal accounting
controls relating to the services provided by Northern under this Agreement.
Such reports shall be of sufficient scope and in sufficient detail, as may
reasonably be required by the Trust, its Administrator or its independent public
accountants, to provide reasonable assurance that any material weaknesses with
respect to such accounting system and such internal accounting controls would be
disclosed by such examination, and, if there are no such weaknesses, shall so
state.

          14. Systems. Northern represents that it has, and it agrees to
maintain, sufficient systems capability to perform its obligations under this
Agreement and the Current Prospectus.

          15. Security. Northern represents and warrants that the various
procedures and systems which it has implemented with regard to safeguarding from
loss or damage attributable to fire, theft or any other cause the Trust's
records and other data and Northern's records, data, equipment, facilities and
other property used in the performance of its obligations hereunder are adequate
and that it will make such changes therein from time to time as in its judgment

all purposes herein be deemed to be an independent contractor and shall, unless
otherwise expressly provided herein or authorized by the Trustees of the Trust
or its Administrator, respectively, from time to time, have no authority to act
for or represent the Trust or the Administrator in any way or otherwise be
deemed an agent of the Trust or its Administrator. The services of Northern
hereunder are not deemed exclusive and Northern shall be free to render similar
services to others so long as its services under this Agreement are not impaired
thereby.

of the Trust and the obligations hereunder are not binding upon any of the
Trustees, Officers or holders of Units of the Trust individually but are binding

               payment of the Trust's bills.

     (b)  The Administrator, in the performance of its duties hereunder, shall
          act in conformity with the Trust Agreement, By-Laws, Registration
          Statement and Prospectus and Statement of Additional Information and
          with the instructions and directions of the Trustees of the Trust, and
          will use its best efforts to conform to the requirements of the 1940
          Act and all other applicable federal and state laws, regulations and
          rulings.

     (c)  The Administrator shall render to the Trustees of the Trust such
          periodic and special reports as the Trustees may reasonably request.

     (d)  The services of the Administrator hereunder are not deemed exclusive
          and the Administrator shall be free to render similar services to
          others so long as its services under this Agreement are not impaired
          thereby.

     (e)  Provide officers to the Trust.

4.  Expenses.

     (a)  During the term of this Agreement, the Administrator will pay all
          expenses incurred by it in connection with the performance of its
          duties under paragraph 3 hereof, other than the out-of-pocket cost of
          the preparations, submissions, updatings and filings referred to in
          paragraph 3(a)(iii).

     (b)  If, in any fiscal year, the sum of a Portfolio's expenses (including
          the fee payable pursuant to paragraph 5 hereof, but excluding the
          investment advisory fee and transfer agency fee payable to Northern
          pursuant to its agreements with the Trust referred to in paragraph 2
          hereof and servicing fees, and extraordinary expenses such as taxes,
          interest, and indemnification expenses) exceeds on an annualized basis
          .10% of a Portfolio's average net assets (0.25% for each International
          Portfolio, including the International Growth Portfolio, International
          Bond Portfolio and International Equity Index Portfolio) for such
          fiscal year, the Administrator will reimburse each Portfolio for the
          amount of such excess in accordance with the following timetable.
          Expense reimbursements, if any, will be calculated and paid monthly.
          The amount of the reimbursement paid by the Administrator to each
          Portfolio will be computed as of the end of each month by (1)
          determining the difference between the Portfolio's accrued annualized
          expense ratio and the above percentage limitation; (2) multiplying
          this percentage by the Portfolio's year to date average net asset
          value for such month to obtain the cumulative dollar amount of such
          excess; and (3) subtracting from the cumulative dollar amount of such
          excess the cumulative amount of reimbursements made to such Portfolio
          by the Administrator since the beginning of the fiscal year. A
          positive remainder represents the amount to be paid by the
          Administrator to the Portfolio; a negative remainder represents the
          amount to be paid by the Portfolio to the Administrator.

     (c)  In the event that the reimbursements described in paragraph (b) to the
          Portfolios cause the aggregate net administration fees actually earned
          by Goldman Sachs on behalf of all the Fund's Portfolios during any
          fiscal year pursuant to the Administration Agreement to be less than
          the sum of (a) $1 million for the first 12 Portfolios that were
          actively engaged in operations during any part of such fiscal year
          plus (b) $50,000 for each additional Portfolio that was actively
          engaged in operations during any part of such fiscal year (the
          "Minimum Fee"), Northern agrees to pay to Goldman Sachs, promptly
          following the close of each fiscal year of the Fund, an amount equal
          to the difference between such earned net administration fees and the
          Minimum Fee.

                                      -3-

5.  Compensation.

     (a)  For the services provided and the expenses assumed by the
          Administrator for each non-international portfolio (which include
          supervision with respect to the Trust's non-investment advisory
          operations) pursuant to the Agreement, the Trust will pay to the
          Administrator as full compensation therefor a fee at an annual rate of
          .10% of each Portfolio's average daily net assets.

          For the services provided and the expenses assumed by the
          Administrator for an International Portfolio, including the
          International Growth Portfolio, International Bond Portfolio and
          International Equity Index Portfolio (which include supervision with
          respect to the Trust's non-investment advisory operations) pursuant to
          the Agreement, the Trust will pay to the Administrator as full
          compensation therefor a fee at an annual rate of .15% of each
          Portfolio's average daily net assets.

     (b)  The fee will be computed based on net assets on each day and will be
          paid to the Administrator monthly.

     6.  Books and Records.  The Administrator agrees to maintain such records
with respect to its activities hereunder as may be required or as are
appropriate.  The Administrator further agrees that all records which it
maintains for the Trust are the property of the Trust and it will surrender
promptly to the Trust any of such records upon the Trust's request.


     7.  Indemnification.

     (a)  The Trust hereby agrees to indemnify and hold harmless the
          Administrator, its officers, partners and employees and each person,
          if any, who controls the Administrator (collectively the "Indemnified
          Parties") against any and all losses, claims, damages or liabilities,
          joint or several, to which they or any of them may become subject
          under the 1933 Act, the Securities Exchange Act of 1934, the 1940 Act
          or other federal or state statutory law or regulation, at common law
          or otherwise, insofar as such losses, claims, damages or liabilities
          (or actions in respect thereof) arise out of or are based upon:

          (i)  any untrue statement or alleged untrue statement of a material
               fact or any omission or alleged omission to state a material fact
               required to be stated or necessary to make the statements made
               not misleading in the Registration Statement, the Prospectus or
               the Statement of Additional Information, or any application or
               other document filed in connection with the qualification of the
               Trust or Units of any Portfolio under the Blue Sky or securities
               laws of any jurisdiction ("Application"), except insofar as such
               losses, claims, damages or liabilities (or actions in respect
               there of) arise out of or are based upon any such untrue
               statement or omission or alleged untrue statement or omission
               either pertaining to a breach of the Administrator's duties in
               connection with this Agreement or the Distribution Agreement of
               even date herewith between the Administrator and the Trust, made
               in reliance upon and in conformity with information furnished by
               or on behalf of the Administrator for use in connection with the
               Registration Statement, the Prospectus and Statement of
               Additional Information or any Application, or

          (ii) subject to clause (i) above, the Administrator acting hereunder
               or under the Distribution Agreement of even date herewith between
               the

                                      -4-
<PAGE>
 
               Administrator and the Trust;

and the Trust will reimburse each Indemnified Party for any legal or other
incurred by such Indemnified Party in connection with investigating or
defending any such loss, claim, damage, liability or action.

     (b)  If the indemnification provided for in paragraph 7(a) is due in
          accordance with the terms of such paragraph but is for any reason held
          by a court to be unavailable from the Trust, then the Trust shall
          contribute to the aggregate amount paid or payable by the Trust and
          the Indemnified Parties as a result of such losses, claims, damages or
          liabilities (or actions in respect thereof) in such proportion as is
          appropriate to reflect (i) the relative benefits received by the Trust
          and such Indemnified Parties in connection with the operations of the
          Trust, (ii) the relative fault of the Trust and such Indemnified
          Parties, and (iii) any other relevant equitable considerations. The
          Trust and the Administrator agree that it would not be just and
          equitable if contribution pursuant to this subparagraph (b) were
          determined by pro rata allocation or any other method of allocation
          which does not take account of the equitable considerations referred
          to above in this subparagraph (b). The amount paid or payable as a
          result of the losses, claims, damages or liabilities (or actions in
          respect thereof) referred to above in this subparagraph (b) shall be
          deemed to include any legal or other expense incurred by the Trust and
          the Indemnified Parties in connection with investigating or defending
          any such loss, claim, damage, liability or action. No person guilty of
          fraudulent misrepresentation (within the meaning of Section 11(f) of
          the 1933 Act) shall be entitled to contribution from any person who
          was not guilty of such fraudulent misrepresentation.

     (c)  It is understood, however, that nothing in this paragraph 7 shall
          protect any Indemnified Party against, or entitle any Indemnified
          Party to indemnification against, or contribution with respect to, any
          liability to the Trust or its Unit-holders to which such Indemnified
          Party is subject, by reason of its willful misfeasance, bad faith or
          gross negligence in the performance of its duties, or by reason of any
          reckless disregard of its obligations and duties, under this Agreement
          or the Distribution Agreement, or otherwise to an extent or in a
          manner inconsistent with Section 17 of the 1940 Act.

     8.  Duration and Termination.  Insofar as the holders of Units representing
the interests in the Current Portfolios are affected by this Agreement, it shall
continue, unless sooner terminated as provided herein, until April 30, 1998,
and, insofar as the holders of Units representing the interests in each of the
other Portfolios are affected by this Agreement, it shall continue until April
30 of the year following the year in which the Portfolio becomes a Portfolio
hereunder, and thereafter shall continue automatically for periods of one year
so long as each such latter continuance is approved at least annually (a) by the
vote of a majority of the Trustees of the Trust who are not parties to this
Agreement or interested persons (as defined by the 1940 Act) of any such party,
cast in person at a meeting called for the purpose of voting on such approval,
and (b) by the Trustees of the Trust or by vote of a majority of the outstanding
Units (as defined with respect to voting securities in the 1940 Act)
representing the interests in such Portfolio.  This Agreement may be terminated
by the Trust as to any Portfolio at any time, without the payment of any
penalty, by vote of a majority of the Trustees of the Trust or by vote of a
majority of the outstanding Units (as so defined) representing the interests in
the Portfolio affected thereby on 60 days' written notice to the Administrator,
or by the Administrator at any time, without the payment of any penalty, on 60
days' written notice to the Trust.  This Agreement will automatically and
immediately terminate in the event of its assignment (as defined by the 1940
Act).

     9.  Status of Administrator as Independent Contractor.  The Administrator
shall for all purposes herein be deemed to be an independent contractor and
shall, unless otherwise expressly provided herein or authorized by the Trustees
of the Trust from time to time, have no authority to act for or represent the
Trust in any way or otherwise be deemed an agent of the Trust.  The
Administrator represents and warrants to the Trust that it is duly organized as
a New York limited partnership and is and at all times will remain duly
authorized and licensed to carry out its services as contemplated herein.

                                      -5-
<PAGE>
 
     10.  Amendment of Agreement.  This Agreement may be amended by mutual
consent provided that such amendment is approved by vote of a majority of those
Trustees of the Trust who are not parties to this Agreement or interested
persons (as defined in the 1940 Act) of any such party, cast in person at a
meeting called for the purpose of voting on such amendment.

     11.  Unitholder Liability.  This Agreement is executed by or on behalf of
the Trust with respect to each of its Portfolios and the obligations hereunder
are not binding upon any of the Trustees, officers or Unitholders of the Trust
individually but are binding only upon the Portfolio to which such obligations
pertain and the assets and property of such Portfolio.

     12.  Miscellaneous.  The Trust's Declaration of Trust as amended to date is
on file with the Secretary of The Commonwealth of Massachusetts. The captions in
this Agreement are included for convenience of reference only and in no way
define or delimit any of the provisions hereof or otherwise affect their
construction or effect.  If any provision of this Agreement shall be held or
made invalid by a court decision, statute, rule or otherwise, the remainder of
this Agreement shall not be affected thereby.  This Agreement shall be construed
in accordance with applicable federal law and (except as to paragraph 11 hereof
which shall be construed in accordance with the laws of The Commonwealth of
Massachusetts) the laws of the State of Illinois and shall be binding upon and
shall inure to the benefit of the parties hereto and their respective successors
(subject to the last sentence of paragraph 8) and, to the extent provided in
paragraph 7 hereof, each Indemnified Party.  Anything herein to the contrary
notwithstanding, this Agreement shall not be construed to require, or to impose
any duty upon, either of the parties to do anything in violation of any
applicable laws or regulations.


     IN WITNESS WHEREOF, the parties hereto have caused this instrument to be
executed as of the day and year first above written.

Re:  Registration Statement on Form N-1A/Issuance of Shares
     ------------------------------------------------------

Ladies and Gentlemen:

     We have acted as counsel to The Benchmark Funds, a Delaware business trust
(the "Trust") organized under an Agreement and Declaration of Trust dated July
1, 1997 (the "Declaration of Trust"), in connection with the registration under
the Securities Act of 1933, as amended, pursuant to a Registration Statement on
Form N-1A (File Nos. 2-80543 and 811-3605) (the "Registration Statement"), of:
(a) four separate classes of shares of beneficial interest (known as Class A
Shares, Class B Shares, Class C Shares and Class D Shares) in each of the
following fourteen series, or portfolios, of the Trust - U.S. Government
Securities Portfolio, Short-Intermediate Bond Portfolio, U.S. Treasury Index
Portfolio, Bond Portfolio, Intermediate Bond Portfolio, International Bond
Portfolio, Balanced Portfolio, Equity Index Portfolio, Diversified Growth
Portfolio, Focused Growth Portfolio, Small Company Index Portfolio,
International Equity Index Portfolio, International Growth Portfolio and Global
Asset Portfolio; and (b) three separate classes of shares of beneficial interest
(known as Shares, Service Shares and Premier Shares) in each of the following
four series, or portfolios, of the Trust - Government Select Portfolio,
Government Portfolio, Diversified Assets Portfolio and Tax-Exempt Portfolio.
Shares of the aforesaid classes of shares of beneficial interest are referred to
hereinafter as "Shares." The Trust is authorized to issue an unlimited number of
Shares in each of the aforesaid classes and series.

     We have reviewed the Registration Statement and the Trust's Declaration of
Trust, its by-laws and certain resolutions adopted by its Trustees, and have
considered such other legal and factual matters as we have deemed appropriate.
<PAGE>
 
                                      -2-

     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 registered
under the Registration Statement will be, when issued against payment therefor
as described therein, 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 of Shares, 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 Post-Effective Amendment No. 38 to the Trust's
Registration Statement on Form N-1A. 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 may 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,

                                       /s/ Drinker Biddle & Reath LLP

                              CONSENT OF COUNSEL



     We hereby consent to the use of our name and to the references to our Firm
under the caption "Additional Trust Information - Counsel and Auditors" in the 
Statement of Additional Information included in Post-Effective Amendment No. 38 
to the Registration Statement (1933 Act No. 2-80543; 1940 Act No. 811-3605) on 
Form N-1A under the Securities Act of 1933, as amended, of The Benchmark Funds. 
This consent does not constitute a consent under section 7 of the Securities Act
of 1933, nd in consenting to the use of our name and the references to our Firm

                         d =           20.22

                         Thus, the 30-Day Yield computed to           4.28%
                                                                    ======

SEC 30-DAY YIELD (Assuming no fee waivers) - Period ending August 31, 1993
- --------------------------------------------------------------------------


     Formula used in calculating SEC 30-day yield for the U.S. Government
     Securities Portfolio:


     YIELD = 2* [((a - b)/(c * d) + 1) 6 - 1]


     Where:

          a = dividends and interest earned during the period
          b = expenses accrued for the period
          C = the average daily number of units outstanding during August 2-31, 
              1993
          d = the maximum offering price per unit on August 31, 1993

     For the 30-day period ending August 31, 1993, these variables were as follows
     for the U.S. Treasury Index Portfolio:

                         a =      121,695.55
                         b =       32,682.00
                         c =    1,571,943.00
                         d =           20.22

                         Thus, the 30-Day Yield computed to           3.38%
                                                                     ======
