Q.       WHAT IS NORTHERN FUNDS?

A.       Northern Funds is an open-end management investment company (commonly
         known as a mutual fund) that offers investors the opportunity to invest
         in different investment portfolios, each having separate investment
         objectives and policies. Northern Funds presently consists of nineteen
         portfolios, including money market, domestic and international fixed
         income and equity portfolios.

         MONEY MARKET FUNDS

         MONEY MARKET FUND seeks 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.

         U.S. GOVERNMENT MONEY MARKET FUND seeks to maximize current income to
         the extent consistent with the preservation of capital and maintenance
         of liquidity by investing exclusively in obligations of the U.S.
         government, its agencies and instrumentalities and related repurchase
         agreements.

         MUNICIPAL MONEY MARKET FUND seeks, to the extent consistent with the
         preservation of capital and prescribed portfolio standards, a high
         level of income exempt from regular federal income tax by investing
         primarily in municipal instruments.

         U.S. GOVERNMENT SELECT MONEY MARKET FUND seeks to maximize current
         income to the extent consistent with the preservation of capital and
         maintenance of liquidity by investing solely in obligations of the U.S.
         Government, its agencies and instrumentalities.

         CALIFORNIA MUNICIPAL MONEY MARKET FUND seeks to provide to its
         shareholders, to the extent consistent with the preservation of capital
         and prescribed portfolio standards, a high level of income exempt from
         regular federal income tax and California state personal income tax.

         FIXED INCOME FUNDS

         U.S. GOVERNMENT FUND seeks a high level of current income from
         investment in U.S. Government securities while maintaining a
         dollar-weighted average maturity between one and ten years.


                                       -1-

         in fixed income securities while maintaining a dollar-weighted average
         maturity between seven and twelve years.

         INTERMEDIATE TAX-EXEMPT FUND seeks a high level of current income
         exempt from regular federal income tax by investing in municipal
         instruments while maintaining a dollar-weighted average maturity
         between three and ten years.

         TAX-EXEMPT FUND seeks a high level of current income exempt from
         regular federal income tax by investing in municipal instruments while
         maintaining a dollar-weighted average maturity between ten and thirty
         years.

         FLORIDA INTERMEDIATE TAX-EXEMPT FUND seeks a high level of current
         income exempt from regular federal income tax by investing in municipal
         instruments while maintaining a dollar-weighted average maturity
         between three and ten years. The Fund intends, but cannot guarantee,
         that its shares will qualify for exemption from the Florida intangibles
         tax.

         INTERNATIONAL FIXED INCOME FUND seeks to maximize total return
         consistent with reasonable risk by investing primarily in bonds and
         other fixed income securities of foreign issuers while maintaining a
         dollar-weighted average maturity between three and eleven years.

         EQUITY FUNDS

         INCOME EQUITY FUND seeks a high level of current income by investing
         principally in convertible and other equity securities with long-term
         capital appreciation as a secondary objective.

         capitalizations that are below the median capitalization of stocks

         INTERNATIONAL SELECT EQUITY FUND seeks long-term capital appreciation
         by investing principally in common stocks of foreign issuers that
         Northern Trust believes to be growing more rapidly than their
         respective markets.

         TECHNOLOGY FUND seeks long-term capital appreciation by investing
         principally in equity securities and securities convertible into common
         stock.

         STOCK INDEX FUND seeks investment results approximating the aggregate
         price and dividend performance of the securities included in the
         Standard & Poor's 500(R) Composite Stock Price
         Index (the "S&P 500 Index").

         Each portfolio is described in further detail in this Prospectus.

Q.       WHO ADVISES THE FUNDS?

A.       The Northern Trust Company ("Northern Trust"), the principal subsidiary
         of Northern Trust Corporation, serves as investment adviser to Northern
         Funds. Northern Trust also serves as the Funds' transfer agent and
         custodian. Northern Trust and its affiliates administered over $692.9
         billion in assets as of June 30, 1996 in various capacities, including
         approximately $120 billion for which Northern Trust had investment
         management responsibility. See "Management."

Q.       HOW DOES ONE BUY AND REDEEM SHARES?

A.       Shares of the Funds are distributed by Sunstone Financial Group, Inc.
         Shares may be purchased directly from Northern Funds or through a
         qualified account at Northern Trust or certain other institutions.
         Shares are sold and redeemed without any purchase or redemption charge
         by Northern Funds, although Northern Trust and other institutions may
         charge their customers for their services in connection with
         investments. The minimum initial investment for purchases directly with
         Northern Funds is $2,500 ($500 for an IRA; $250 for a spousal IRA; and
         $250 under the Automatic Investment Plan). The minimum for subsequent
         investments is $50. Northern Trust or other organizations may impose
         particular customer account requirements such as minimum account sizes.

         The Stock Index Fund will not commerce operations until it has received
         orders for the purchase of its shares aggregating $5 million, and will
         not accept payment for the purchase of shares until orders in this
         aggregate amount are received. Northern Trust anticipates that the
         Stock Index Fund will commence operations in the Fall of 1996. Under
         normal circumstances at least 65% of the Fund's total assets

                                       -3-
<PAGE>   14
         will be invested in the issues included in the S&P 500 Index.

         Additional share purchase and redemption information for both purchases
         and redemptions directly with Northern Funds or through qualified
         accounts is provided below under "Opening an Account and Purchasing
         Shares" and "Redeeming and Exchanging Shares."

Q.       WHAT SHAREHOLDER SERVICES ARE AVAILABLE?

A.       Northern Funds offers the advantage of automatic dividend reinvestment
         in shares of the same Fund or in another Northern Fund, exchange
         privileges among Northern Funds should your investment goals change,
         telephone exchange and redemption privileges, an Automatic Investment
         Plan (with a reduced minimum initial investment) and a Systematic
         Withdrawal Plan. See "Opening an Account and Purchasing Shares" and
         "Redeeming and Exchanging Shares." Shares of Northern Funds may be
         purchased in connection with a variety of tax-sheltered retirement
         plans. See "Further Information -- Retirement Plans."

Q.       WHEN ARE DISTRIBUTIONS MADE?

A.       Dividends from the net investment income of the Money Market Funds, the
         U.S. Government Fund, the Fixed Income Fund, the Intermediate
         Tax-Exempt Fund, the Tax-Exempt Fund and the Florida Intermediate
         Tax-Exempt Fund are declared daily and paid monthly. Dividends of the
         International Fixed Income Fund are declared daily and paid quarterly.
         Dividends of the other Funds are declared and paid as follows: Income
         Equity Fund -- monthly; Growth Equity Fund and Stock Index Fund --
         quarterly; Select Equity Fund, Small Cap Fund, International Growth
         Equity Fund, International Select Equity Fund and Technology Fund --
         annually.

         Net realized capital gains of each Fund are distributed at least
         annually. See "Distributions and Taxes."

Q.       WHAT ARE THE POTENTIAL RISKS PRESENTED BY THE FUNDS' INVESTMENT
         PRACTICES?

A.       Investing in the Funds involves the risks common to any investment in
         securities. The market value of fixed income securities, which
         constitutes a major part of the investments of several of the Funds,
         will generally vary inversely with changes in prevailing interest rates
         as described below under "Investment Information -- Fundamentals of
         Fixed Income Investing." The Fixed Income Funds will invest in
         securities rated investment grade or higher, or will be unrated
         securities of comparable quality.

                                       -4-
<PAGE>   15
         However, the International Funds may invest up to 5%, and the Equity
         Funds may invest up to 10% of their total assets (35% for the Income
         Equity Fund), in convertible securities rated below investment grade.
         Several of the Funds may invest a substantial portion of their assets
         in foreign securities directly, and indirectly through the purchase of
         European Depository Receipts ("EDRs") and American Depository Receipts
         ("ADRs"). These Funds may also enter into foreign currency exchange
         contracts. Foreign securities may be subject to certain risks in
         addition to those inherent in U.S. investments, including the possible
         imposition of exchange control regulations, freezes on convertibility
         of currency and adverse changes in foreign currency exchange rates. The
         International Fixed Income Fund, as well as Northern Funds' two other
         international investment portfolios, may concentrate investments in
         issuers located in certain industrialized countries and may also invest
         in issuers located in emerging countries.

         Certain risks are presented by the California Municipal Money Market
         Fund and the Florida Intermediate Tax-Exempt Fund as a result of their
         investments in Municipal Instruments of issuers located in particular
         states. See "California Municipal Money Market Fund and Florida
         Intermediate Tax-Exempt Fund - Additional Risks and Considerations." In
         addition, the California Municipal Money Market, Florida Intermediate
         Tax-Exempt and International Fixed Income Funds are non-diversified
         funds, which means their portfolios can be dependent upon the
         performance of a smaller number of securities than is the case with the
         other Funds, which are diversified funds. Each Fund (other than the
         Money Market Funds) may engage in certain transactions involving puts
         and calls. Further, certain of the Funds may invest in the stocks of
         smaller companies which present greater risk and price volatility. The
         Funds may lend their securities and enter into repurchase agreements
         and reverse repurchase agreements with qualifying banks and
         broker/dealers which may involve leveraging. The Funds may also
         purchase eligible securities on a "when-issued" basis and may purchase
         or sell securities on a "forward commitment" or "delayed settlement"
         basis. The Funds may invest up to 15% (10% in the case of the Money
         Market Funds) of their net assets in illiquid securities.

         The Funds may also purchase "derivative" instruments. "Derivative"
         instruments are instruments that derive value from the performance of
         underlying assets, interest or currency exchange rates, or indices, and
         include (but are not limited to) 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

                                       -5-
<PAGE>   16



         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 Fund 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, complete information is lacking regarding their
         actual performance over entire market cycles. Northern Trust will
         evaluate the risks presented by the "derivative" instruments purchased
         by the Funds, and will determine, in connection with its day-to-day
         management of the Funds, how they will be used in furtherance of the
         Funds' investment objectives. It is possible, however, that Northern
         Trust's evaluations will prove to be inaccurate or incomplete and, even
         when accurate and complete, it is possible that the Funds will, because
         of the risks discussed above, incur loss as a result of their
         investments in "derivative" instruments.

         The foregoing is a summary of certain of the potential risks presented
         by the Funds' investment practices. Details regarding these and other
         risks presented by the policies of the Funds are described under
         "Additional Investment Information, Risks and Considerations."

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

         The above information reflects the expenses these Funds incurred for
Northern Funds' fiscal year ended March 31, 1996. Since the Technology Fund did
not commence investment operations until April 1, 1996 and the Stock Index Fund
had not commenced operations as of the date of this prospectus, the information
for those Funds reflects the estimated expenses those Funds expect to pay during
the current fiscal year. Without the fee reductions, waivers and reimbursements,
"Management Fees" would be 1.00%, 1.00%, 1.20%, 1.20%, 1.20%, 1.20%, 1.20% and
 .60%, respectively, of the average daily net assets of the Income Equity, Growth
Equity, Select Equity, Small Cap, International Growth Equity, International
Select Equity, Technology and Stock Index Funds; "Other Expenses" would be .48%,
 .36%, .71%, .41%, .45%, .51%, .45% and .90%, respectively; and "Total Operating
Expenses" would be 1.48%, 1.36%, 1.91%, 1.61%, 1.65%, 1.71%, 1.65% and 1.51%,
respectively. In addition, during the last fiscal year these Funds did not, and
during the current fiscal year do not expect to, pay any 12b-1 fees (otherwise
payable at an annual rate of up to 0.25%) under Northern Funds' Distribution and
Service Plan. For more expense information, see "Management."

INVESTMENT INFORMATION

The investment objectives and policies of each of the Funds are described below.
Additional information regarding the securities, investment techniques and
restrictions of each Fund are described under "Additional Investment
Information, Risks and Considerations."

MONEY MARKET FUNDS

MONEY MARKET FUND. The investment objective of the Money Market Fund is to seek
to maximize current income to the extent consistent with the preservation of
capital and the maintenance of liquidity by investing exclusively in
high-quality money market instruments. In pursuing its investment objective, the
Money Market Fund may invest in a broad range of government, bank and commercial
obligations that are available in the money markets. In particular, the Fund 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 with 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"), D-2 or higher by Duff
& Phelps Credit Co. ("Duff"), F-2 or higher by Fitch Investors Service, Inc.
("Fitch") or TBW-2 or higher by Thomson BankWatch, Inc. ("TBW");

         (D)      high grade corporate bonds and unrated notes, paper and other
instruments that are of comparable quality as determined by Northern Trust;

         (E)      rated asset-backed securities of non-governmental issuers
(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)      dollar-denominated securities issued or guaranteed by one or
more foreign governments or political subdivisions, agencies or
instrumentalities thereof;


                                      -16-
<PAGE>   27
         (H)      repurchase agreements relating to the above instruments; and

         (I)      securities issued or guaranteed by state or local governmental
bodies.

U.S. GOVERNMENT MONEY MARKET FUND.  The investment objective of the U.S.
Government Money Market Fund is also to seek to maximize current income to the
extent consistent with the preservation of capital and the maintenance of
liquidity by investing exclusively in high-quality money market instruments.
The U.S. Government Money Market Fund seeks to achieve its investment objective
by investing in:

         (A)      securities issued or guaranteed as to principal and interest
by the U.S. Government or by any of its agencies or instrumentalities (including
the International Bank for Reconstruction and Development);

         (B)      repurchase agreements relating to the above instruments; and

         (C)      custodial receipts with respect to securities issued or
guaranteed as to principal and interest by the U.S. Government or by any of its
agencies or instrumentalities.

MUNICIPAL MONEY MARKET FUND. The investment objective of the Municipal Money
Market Fund is to seek, to the extent consistent with the preservation of
capital and prescribed portfolio standards, a high level of income exempt from
regular federal income tax by investing primarily in municipal instruments. The
Municipal Money Market Fund seeks to achieve its investment objective by
investing 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, D-2 or higher by Duff 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, D-2 or higher by Duff or F-2
or higher by Fitch;

         (C)      high grade municipal bonds and unrated notes, paper or other
instruments that are of comparable quality as determined by Northern Trust; 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.


                                      -17-
<PAGE>   28
U.S. GOVERNMENT SELECT MONEY MARKET FUND. The investment objective of the U.S.
Government Select Money Market Fund 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 U.S.
Government Select Money Market Fund seeks to achieve its investment objective by
investing solely in securities issued or guaranteed as to principal and interest
by the U.S. Government or by any of its agencies or instrumentalities.

         In making investment decisions, Northern Trust will seek to acquire,
during 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
Tennessee Valley Authority, Federal Home Loan Bank, Federal Farm Credit Banks
Funding Corp. and the Student Loan Marketing Association. The Fund intends to
limit investments to only the foregoing exempt U.S. Government securities.
However, under extraordinary circumstances, such as when appropriate exempt
securities are unavailable, the Fund may make investments in non-exempt U.S.
Government securities and cash equivalents, and may hold uninvested cash. See
"Distributions and Taxes" below for certain tax considerations.

CALIFORNIA MUNICIPAL MONEY MARKET FUND. The investment objective of the
California Municipal Money Market Fund is to seek 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 and California
state personal income tax. The California Municipal Money Market Fund seeks to
achieve its investment objective by investing 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, D-2
or higher by Duff 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, D-2 or higher by Duff or F-2
or higher by Fitch;

         (C) high grade municipal bonds and unrated notes, paper or other
instruments that are of comparable quality as determined by Northern Trust; 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.

                                      -18-
<PAGE>   29
         Because the California Municipal Money Market Fund concentrates its
investments in obligations issued by California and its political subdivisions,
an investment in this Fund may be riskier than an investment in the other Money
Market Funds.

OTHER INFORMATION. All securities acquired by the Money Market Funds will be
determined at the time of purchase by Northern Trust to present minimal credit
risks and will be "Eligible Securities" as defined by the Securities and
Exchange Commission (the "SEC"). Eligible Securities are (a) securities that
either (i) 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 (ii) are comparable in priority and security with
an instrument issued by an issuer which has such ratings, and (b) securities
that are unrated (including securities of issuers that have long-term but not
short-term ratings) but are of comparable quality as determined by Northern
Trust.

         Each Money Market Fund is managed so that the average maturity of all
instruments in the Fund (on a dollar-weighted basis) will not exceed 90 days. In
no event will the Money Market Funds purchase any securities which mature more
than 397 days from the date of purchase (except for certain variable and
floating rate instruments and securities collateralizing repurchase agreements).
Securities in which the Money Market Funds invest may not earn as high a level
of income as longer term or lower quality securities, which generally have
greater market risk and more fluctuation in market value.

         As a matter of fundamental policy, changeable only with the approval of
the holders of a majority of the outstanding shares of a Fund, at least 80% of
the annual gross income of the Municipal Money Market Fund and the California
Municipal Money Market Fund will be derived from debt instruments, the interest
on which is, in the opinion of bond counsel or counsel for the issuers, exempt
from regular income tax ("Municipal Instruments"), except in extraordinary
circumstances such as when Northern Trust believes that market conditions
indicate that the Fund should adopt a temporary defensive posture by holding
uninvested cash or investing in taxable short-term securities ("Taxable
Investments"). In addition, as a non-fundamental policy, under normal market
conditions at least 65% of the value of the California Municipal Money Market
Fund's total assets will be invested in Municipal Instruments the interest on
which, in the opinion of bond counsel for the issuers, is exempt from California
state personal income tax ("California Municipal Instruments"). These opinions
may contain various assumptions, qualifications or exceptions that are
reasonably acceptable to Northern Trust. The Municipal Money Market and
California Municipal Money Market Funds are not limited in the amount of

                                      -19-
<PAGE>   30
their assets that may be invested in "private activity bonds" the interest on
which may be treated as an item of tax preference to shareholders under the
federal alternative minimum tax. Taxable Investments will consist exclusively of
instruments that may be purchased by the Money Market Fund. Under normal market
conditions, Taxable Investments will not exceed 20% of the value of the total
assets of either Fund; during temporary defensive periods, however, all or any
portion of a Fund's assets may be invested in such instruments.

FIXED INCOME FUNDS

U.S. GOVERNMENT FUND AND FIXED INCOME FUND. The investment objective of both the
U.S. government Fund and the Fixed Income Fund is to seek a high level of
current income.

         The U.S. Government Fund seeks to achieve its objective by investing
primarily (at least 65% of the value of its total assets during normal market
conditions) in securities issued or guaranteed by the U.S. Government, its
agencies and instrumentalities and repurchase agreements relating to such
securities. These securities may include mortgage-related securities. The Fund's
dollar-weighted average maturity will be between one and ten years.

         The Fixed Income Fund seeks to achieve its objective by investing in a
broad range of fixed income securities while maintaining a dollar-weighted
average maturity between seven and twelve years. The Fund will invest primarily
(at least 65% of the value of its total assets during normal market conditions)
in fixed income securities rated investment grade or better at the time of
purchase (within the four highest rating categories of S&P, Duff, Fitch or
Moody's) or, if unrated, of comparable quality as determined by Northern Trust.
These securities may be of all types and in any proportion, including
obligations of the U.S. Government, its agencies or instrumentalities,
obligations of foreign, state and local governments, obligations of U.S. and
foreign corporations, obligations of U.S. and foreign banks and repurchase
agreements relating to such obligations. The Fund may purchase bonds,
debentures, mortgage and other asset-related securities, zero coupon bonds and
convertible debentures. The Fund may also invest in short-term obligations that
are permissible investments for the Money Market Fund. The obligations of a
foreign issuer will not be purchased by the Fixed Income Fund if, as a result of
the purchase, more than 20% of the Fund's total assets will be invested in the
obligations of issuers within a single foreign country.

         Each Fund may utilize options, interest rate swaps and futures
contracts and the Fixed Income Fund may enter into forward currency contracts as
described more fully under "Additional Investment Information, Risks and
Considerations."

INTERMEDIATE TAX-EXEMPT FUND, TAX-EXEMPT FUND AND FLORIDA INTERMEDIATE
TAX-EXEMPT FUND. The investment objective of the Intermediate Tax-Exempt Fund is
to seek a high level of current income exempt from regular federal income tax by
investing in a broad range of Municipal Instruments while maintaining a
dollar-weighted average maturity between three and ten years. The Tax- Exempt
Fund seeks a high level of current income exempt from regular federal income tax
by investing in a broad range of Municipal Instruments while maintaining a
dollar- weighted average maturity between ten and thirty years. The Florida
Intermediate Tax-Exempt Fund seeks a high level of current income exempt from
regular federal income tax by investing in Municipal Instruments while
maintaining a dollar-weighted average maturity between three and ten years.

         Municipal Instruments purchased by the Funds will be investment grade
or better at the time of purchase (within the four highest rating categories of
S&P, Duff, Fitch or Moody's) or, if unrated, of comparable quality as determined
by Northern Trust. Short-term obligations will be limited to those obligations
that are permissible investments for the Municipal Money Market Fund.

         As a matter of fundamental policy, changeable only with the approval of
the holders of a majority of the outstanding shares of a Fund, at least 80% of
each Fund's annual gross income will be derived from Municipal Instruments,
except in extraordinary circumstances, such as when Northern Trust believes that
market conditions indicate that a Fund should adopt a temporary defensive
posture by holding uninvested cash or investing in Taxable Investments. In
addition, as a matter of non-fundamental policy which may be changed by the
Board of Trustees, under normal market conditions, at least 65% of the value of
the Florida Intermediate Tax-Exempt Fund's total assets will be invested in
Municipal Instruments issued by the state of Florida and its municipalities,
counties and other taxing districts, as well as other securities exempt from the
Florida intangibles tax ("Florida Municipal Instruments"). "Private activity
bonds," the interest from which may be treated as an item of tax preference to
shareholders under the federal alternative minimum tax ("AMT obligations"), will
not be counted in determining a Fund's investments in Municipal Instruments for
these purposes. Under normal market conditions, Taxable Investments will not
exceed 20% of the value of the total assets of a Fund; during temporary
defensive periods, however, all or any portion of a Fund's assets may be
invested in such instruments. Taxable Investments will consist exclusively of
instruments that may be purchased by the Fixed Income Fund. So long as other
suitable Municipal Instruments are available for investment, the Funds do not
intend to invest in AMT obligations. Certain Municipal Instruments purchased by
the Funds (such as "moral obligation" bonds) may be issued by issuers with a
"moral" but not legal obligation to

                                      -21-
<PAGE>   32
provide for the payment of the bonds. See "Additional Investment Information,
Risks and Considerations -- Description of Securities and Investment Techniques
- -- Municipal Securities."

         The Florida Intermediate Tax-Exempt Fund is classified as a
non-diversified investment company under the Investment Company Act of 1940 (the
"1940 Act"). Investment return on a non-diversified portfolio typically is
dependent upon the performance of a smaller number of securities 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.


INTERNATIONAL FIXED INCOME FUND. The investment objective of the International
Fixed Income Fund is to seek to maximize total return consistent with reasonable
risk. In pursuing its investment objective, the Fund invests primarily (at least
65% of the value of its total assets under normal market conditions) in a broad
range of fixed income securities of foreign issuers. The Fund's dollar-weighted
average maturity will range between three and eleven years.

         Securities purchased by the Fund will generally be rated investment
grade or better at the time of purchase (within the four highest rating
categories of S&P, Duff, Fitch or Moody's) or, if unrated, be of comparable
quality as determined by Northern Trust. These securities may include bonds,
debentures, mortgage and other asset-related securities, zero coupon bonds and
convertible debentures (i.e., debentures that may convert into other fixed
income debt) of foreign governments, their agencies, instrumentalities and
political subdivisions; supranational organizations (e.g., the European
Investment Bank and Inter-American Development Bank); and foreign corporations
and banks. The Fund 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. Currently, a
substantial portion of the Fund's assets are invested in foreign governmental
obligations. Commercial paper and other short-term obligations acquired by the
Fund will be rated within the two highest rating categories at the time of
purchase or, if unrated, will be determined by Northern Trust to be of
comparable quality.

         The International Fixed Income Fund may invest up to 5% of its total
assets in non-investment grade convertible securities that are rated "B" or
higher by at least one major rating agency at the time of purchase or, if
unrated, are determined to be of comparable quality by Northern Trust. See
"Additional Investment Information, Risks and Considerations -- Description of
Securities and Investment Techniques -- Convertible Securities." The
International Fixed Income Fund may make indirect investments

                                      -22-
<PAGE>   33
in foreign securities through the purchase of EDRs and ADRs and may enter into
forward currency contracts and utilize options, swaps and futures contracts as
more fully described under "Additional Investment Information, Risks and
Considerations." Pending investment, as a temporary defensive measure and to
meet anticipated redemption requests, the International Fixed Income Fund may
also invest, in accordance with its investment policies, in various short-term
obligations that are permissible investments for the Money Market Fund, as well
as other similar foreign denominated short-term obligations.

         The International Fixed Income Fund is classified as a non-diversified
investment company under the 1940 Act. Investment return on a non-diversified
portfolio typically is dependent upon the performance of a smaller number of
securities relative to the number held in a diversified portfolio. Consequently,
the change in value of any one security may affect the overall value of the
International Fixed Income Fund more than it would the other Funds.

EQUITY FUNDS

INCOME EQUITY FUND. The investment objective of the Income Equity Fund is to
seek a high level of current income with long-term capital appreciation as a
secondary objective. The Fund seeks to achieve its objective by investing, under
normal market conditions, at least 65% of the value of its total assets in
income-producing convertible and other equity securities. Investments are
selected based on factors such as current income, prospects for growth and
possible capital appreciation. The Fund expects to make significant investments
in convertible securities and, at times, may be fully invested in such
securities. Generally, convertible securities will be rated investment grade or
better at the time of purchase or, if unrated, will be determined to be of
comparable quality by Northern Trust. Investment-grade securities are rated BBB
or higher by S&P, Duff or Fitch or Baa or higher by Moody's. Up to 35% of the
Fund's total assets may, however, be invested in non-investment grade
convertible securities (commonly referred to as "high risk" or "junk" bonds)
that are rated "B" or higher by at least one major rating agency or, if unrated,
are determined to be of comparable quality by Northern Trust. See "Additional
Investment Information, Risks and Considerations -- Description of Securities
and Investment Techniques -- Convertible Securities."

         The Fund may also invest, under normal market conditions, up to 35% of
its total assets in a broad range of bonds and other fixed income securities
rated investment grade or better at the time of purchase. These fixed income
securities will be limited to the types that are permissible investments for the
Fixed Income Fund. The Fund may utilize interest rate swaps as

                                      -23-
<PAGE>   34
described more fully under "Additional Investment Information, Risks and
Considerations."

GROWTH EQUITY FUND. The investment objective of the Growth Equity Fund is to
seek long-term capital appreciation. Any income received is incidental to this
objective. The Fund seeks to achieve its objective by investing primarily (at
least 65% of the value of its total assets under normal market conditions) in
equity securities (i.e., common and preferred stocks and convertible securities)
of "growth companies" that Northern Trust believes have demonstrated above
average sales and earnings growth and return on equity relative to their peers
and the general market. Investments are selected based on factors such as
financial condition, market share, product leadership, earnings growth rates as
compared with those of relevant competitors, market valuation in comparison to
other stocks and the stock's own historical norms, improving relative price
trend and other investment criteria. The Fund will have broad sector exposure
and emphasis will be on issue selection rather than sector rotation.

SELECT EQUITY FUND. The investment objective of the Select Equity Fund is to
seek long-term capital appreciation. Any income received is incidental to this
objective. The Fund pursues its objective by investing, under normal market
conditions, at least 65% of the value of its total assets in common stocks of
companies believed by Northern Trust to have superior quality and growth
characteristics. The Fund is not sector-weighted, and will purchase securities
of companies primarily based on their performance in the following areas over a
five-year period: growth of sales, growth of earnings per share, consistency of
earnings per share growth, return on equity, and low debt relative to total
capital. As companies which perform relatively well in some or all of these
categories often retain their earnings to finance current and future growth,
they generally pay low or no dividends. The Fund intends to invest primarily in
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 $500 million.

SMALL CAP FUND. The investment objective of the Small Cap Fund (formally called
the "Small Cap Growth Fund") is to seek long-term capital appreciation. Any
income received is incidental to this objective. In seeking to attain its
investment objective, the Fund will invest, under normal market conditions, at
least 65% of the value of its total assets in equity securities of companies
with market capitalizations, at the time of purchase, that are below the median
capitalization of stocks listed on the New York Stock Exchange. In selecting
stocks, Northern Trust will consider the relationship between price and book
value, and other factors such as trading volume and bid-ask spreads in an

                                      -24-
<PAGE>   35
effort to allow the Fund to achieve cost-effective diversification.

         While Northern Trust believes that smaller companies can provide
greater growth potential than larger, more mature firms, investing in the
securities of such companies also involves greater risk, portfolio price
volatility and cost. Historically, small capitalization stocks, which will be
the Fund's primary investments, and stocks of recently organized companies, in
which the Fund may also invest, have been more volatile in price than the larger
capitalization stocks included in the Standard & Poor's 500 Stock Index (the
"S&P 500 Index"). Among the reasons for this greater price volatility are the
lower degree of market liquidity (the securities of companies with small stock
market capitalizations may trade less frequently and in limited volume) and the
greater sensitivity of small companies to changing economic conditions. For
example, these companies are associated with higher investment risk due to the
greater business risks of small size and limited product lines, markets,
distribution channels and financial and managerial resources.

         The values of small company stocks will frequently fluctuate
independently of the values of larger company stocks. Small company stocks may
decline in price as large company stock prices rise, or rise in price as large
company stock prices decline. You should, therefore, expect that the net asset
value of the Fund's shares will be more volatile than, and may fluctuate
independently of, broad stock market indices such as the S&P 500 Index.

         The additional costs associated with the acquisition of small company
stocks include brokerage costs, market impact costs (that is, the increase in
market prices which may result when the Fund purchases thinly traded stock) and
the effect of the "bid-ask" spread in small company stocks. These costs will be
borne by all shareholders and may negatively impact investment performance.

INTERNATIONAL GROWTH EQUITY FUND. The investment objective of the International
Growth Equity Fund is to seek long-term capital appreciation. Any income
received is incidental to this objective. The Fund seeks to achieve its
objective by investing principally in common and preferred stocks and securities
convertible into common stock of foreign issuers. The Fund will, under normal
market conditions, invest at least 65% of the value of its total assets in
equity securities. The Fund emphasizes stocks of companies that Northern Trust
believes to be growing more rapidly than their respective markets and that have
low debt ratios and above-average returns on equity. The Fund is country-
weighted but not sector-weighted and selects investments based on such factors
as financial condition, market share, product leadership, earnings growth rates
as compared with those of

                                      -25-
<PAGE>   36
relevant competitors in the same local market, market valuation in comparison to
other stocks and the stock's own historical norms, improving relative price
trend and other investment criteria. The Fund 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 Fund invests in
securities listed on foreign and domestic securities exchanges and securities
traded in foreign and domestic over-the-counter markets. See "International
Funds -- Further Information."

INTERNATIONAL SELECT EQUITY FUND. The investment objective of the International
Select Equity Fund is to seek long-term capital appreciation. Any income
received is incidental to this objective. The Fund will pursue its objective by
investing primarily (at least 65% of the value of its total assets under normal
market conditions) in equity securities of foreign issuers that Northern Trust
believes to be growing more rapidly than their respective markets, including
stocks of companies that have medium to smaller stock market capitalizations
(generally less than $1 billion) and that transact a significant level of their
business in countries growing in excess of the world averages. The Fund is
neither country-weighted nor sector-weighted and will invest in stocks of
companies primarily based on their performance in the following areas over a
five-year period: growth of sales, growth of earnings per share, consistency of
earnings per share growth, return on equity and low debt relative to total
capital. As companies which perform relatively well in some or all of these
categories often retain their earnings to finance current and future growth,
they generally pay low or no dividends. The Fund 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 Fund invests in
securities listed on foreign and domestic securities exchanges and securities
traded in foreign and domestic over-the-counter markets. See "International
Funds -- Further Information."

TECHNOLOGY FUND. The Technology Fund's investment objective is to seek long-term
capital appreciation by investing principally in equity securities and
securities convertible into common stock of companies that develop, produce or
distribute products and services related to advances in technology. In addition,
the Fund will, under normal market conditions, invest at least 65% of the value
of its total assets in securities of companies principally engaged in technology
business activities. Northern Trust will consider an issuer principally engaged
in technology business activities if such issuer is listed on the Hambrecht and
Quist Technology Index (the "H&Q Index"), the SoundView Technology Index (the
"Soundview Index"), the technology grouping

                                      -26-
<PAGE>   37
of the S&P 500 or any other comparable technology index. The H&Q Index is an
index of computer and chip makers, biotechnology concerns and other high-tech
companies, and the SoundView Index is an unweighted index consisting of more
than 100 technology companies.

         The Fund emphasizes stocks of companies that Northern Trust believes
have the potential to outperform the market over the next one- to two-year
period. Investments are selected based on factors such as financial condition,
market share, product leadership or market niches, earnings growth rates as
compared with those of relevant competitors, market valuation in comparison to
other stocks and the stock's own historical norms, improving relative price
trend and other investment criteria. Companies in which the Fund may invest
include industrial and business machines; communications; computers, software
and peripheral products; electronics; electronic media; environmental services;
office equipment and supplies; television and video equipment and services; and
satellite technology and equipment. For the purposes of the Fund's industry
concentration policy all of the foregoing companies will be deemed part of the
technology industry. See "Additional Investment Information, Risks and
Considerations -- Investment Restrictions." Certain of the policies of the Fund
present additional risks which are described under "Technology Fund --
Additional Risks and Considerations."

STOCK INDEX FUND. The investment objective of the Stock Index Fund is to seek
investment results approximating the aggregate price and dividend performance of
the securities included in the S&P 500 Index. Although the Fund will not always
hold securities of all 500 issuers included in the S&P 500 Index, it will
normally invest at least 65% of its total assets in the issues included in the
S&P 500 Index. The S&P 500 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 (Standard & Poor's) 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. Standard & Poor's primary
objective for the S&P 500 Index is to be the performance benchmark for the U.S.
equity markets. The companies chosen for inclusion in the S&P 500 Index tend to
be leaders in important industries within the U.S. economy. However, companies
are not selected by Standard & Poor's for inclusion because they are expected to
have superior stock price performance relative to the market in general or other
stocks in particular. Standard & Poor's makes no representation or warranty,
implied or express, to purchasers of Fund shares or any member of the public
regarding the advisability of investing in the Fund or the ability of the S&P
500 Index to track general stock market performance.

                                      -27-
<PAGE>   38
         The Fund 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 500 Index through statistical procedures. As a result, in
this Fund Northern Trust does not employ traditional methods of fund investment
management, such as selecting securities on the basis of economic, financial and
market analysis.

         Northern Trust believes that under normal market conditions, the
quarterly performance of the Fund will be within a .95 correlation with the S&P
500 Index. However, there is no assurance that the Fund will be able to do so on
a consistent basis. Deviations from the performance of the S&P 500 Index
("tracking error") may result from shareholder purchases and redemptions of
shares of the Fund that occur daily, as well as from the expenses borne by the
Fund. Such purchases and redemptions may necessitate the purchase and sale of
securities by the Fund, and the resulting transaction costs may be substantial
because of the number and the characteristics of the securities held. In
addition, transaction costs may be incurred because sales of securities received
in connection with spin-offs and other corporate reorganizations will be made to
conform the Fund's holdings with its investment objective. Tracking error may
also occur due to factors such as the size of the Fund, the maintenance of a
cash reserve pending investment or to meet expected redemptions, changes made in
the S&P 500 Index or the manner in which the S&P 500 Index is calculated or
because the indexing and investment approach of Northern Trust does not produce
the intended goal of the Fund. In the event the performance of the Fund is not
comparable to the performance of the S&P 500 Index, the Board of Trustees will
evaluate the reasons for the deviation and the availability of corrective
measures. If substantial deviation in the Fund's performance were to continue
for extended periods, it is expected that the Board of Trustees would consider
possible changes to the Fund's investment objective.

         The Fund may invest in options, futures contracts and securities issued
by other investment companies (such as Standard & Poor's Depository Receipts
- -"SPDRs") in a manner designed to acheive returns comparable to the S&P 500
Index. The Fund may also invest in certain short-term fixed income securities as
cash reserves. The Fund does not anticipate that it would use 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.

OTHER INFORMATION. The Growth Equity, Income Equity, Select Equity, Small Cap,
International Growth Equity, International Select Equity and Technology Funds
may purchase warrants and rights that entitle the holder to buy equity
securities at a

                                      -28-
<PAGE>   39
specific price for a specific period of time. (Warrants and rights will not be
counted in determining a Fund's investments in equity securities.) In addition
to investing in foreign securities directly, the International Growth Equity and
International Select Equity Funds may make indirect investments in foreign
securities through the purchase of EDRs and ADRs. Each of the Growth Equity,
Income Equity, Select Equity, Small Cap and Technology Funds may invest up to
10% of its net assets in foreign securities directly and indirectly through the
purchase of EDRs, and up to 25% of its net assets in ADRs, in addition to
short-term investments in foreign time deposits as discussed below. The Income
Equity Fund may enter into interest rate swaps and the International Growth
Equity and International Select Equity Funds may enter into currency swaps. The
Funds may purchase convertible securities, enter into forward currency contracts
and utilize options and futures contracts as more fully described under
"Additional Investment Information, Risks and Considerations." Pending
investment, as a temporary defensive measure and to meet anticipated redemption
requests, the Funds may also invest, in accordance with their respective
investment policies, in various short-term obligations that are permissible
investments for the Money Market Fund and, with respect to the International
Growth Equity and International Select Equity Funds, other similar foreign
denominated short-term obligations.

CALIFORNIA MUNICIPAL MONEY MARKET FUND AND FLORIDA INTERMEDIATE TAX-EXEMPT FUND
- -- ADDITIONAL RISKS AND CONSIDERATIONS


         The investments of the California Municipal Money Market Fund in
California Municipal Instruments and the Florida Intermediate Tax-Exempt Fund in
Florida Municipal Instruments raise additional considerations. Payment of the
interest on and the principal of these instruments is dependent upon the
continuing ability of issuers in these states to meet their obligations.

         The California Municipal Money Market Fund's investments include
obligations of California governmental issuers which rely in whole or in part,
directly or indirectly, on real property taxes as a source of revenue.
"Proposition Thirteen" and similar California constitutional and statutory
amendments and initiatives in recent years have restricted the ability of
California taxing entities to increase real property tax revenues. Other
initiative measures approved by California voters in recent years, through
limiting various other taxes, have resulted in a substantial reduction in state
revenues. Decreased state revenues may result in reductions in allocations of
state revenues to local governments.

         Because of the complex nature of the various initiatives mentioned 
above and certain possible ambiguities and

                                      -29-
<PAGE>   40
inconsistencies in their terms and the scope of various exemptions and
exceptions, as well as the impossibility of predicting the level of future
appropriations for state and local California governmental entities, it is not
possible to determine the impact of these initiatives and related measures on
the ability of California governmental issuers to pay interest or repay
principal on their obligations. There have, however, been certain adverse
developments with respect to California Municipal Instruments over the past
several years.

         In addition to the various initiatives discussed above, economic
factors such as the reduction in defense spending, a decline in tourism and high
levels of unemployment have had an adverse impact on the economy of California.
In recent years, these economic factors reduced revenues to the state government
at a time when expenses of state government such as education costs, various
welfare costs and other expenses were rising. Such economic factors adversely
impacted the ability of state and local California governmental entities to
repay debt, and these factors, and others that cannot be predicted, may have an
adverse impact in the future.

         Similarly, if Florida or any of its political subdivisions should
suffer serious financial difficulties to the extent their ability to pay their
obligations might be jeopardized, the ability of such entities to market their
securities, and the value of the Florida Intermediate Tax-Exempt Fund, could be
adversely affected.

         In addition to the risk of nonpayment on California or Florida
Municipal Instruments, if these obligations decline in quality and are
downgraded by the NRSROs, they may become ineligible for purchase by the Funds.
Since there are large numbers of buyers of these instruments, the supply of
California or Florida Municipal Instruments that are eligible for purchase by
the Funds could become inadequate at certain times.

         Investors should consider the greater risk inherent in the
concentration of the California Municipal Money Market Fund and the Florida
Intermediate Tax-Exempt Fund in such obligations versus the safety that comes
with a less geographically concentrated investment portfolio, and should compare
the yield available on a portfolio of California or Florida Municipal
Instruments with the yield of a more diversified portfolio including other
Municipal Instruments before making an investment decision.

         A more detailed description of special factors affecting investments in
California Municipal Instruments and Florida Municipal Instruments is provided
in the Additional Statement.


                                      -30-

TECHNOLOGY FUND -- ADDITIONAL RISKS AND CONSIDERATIONS

         The Technology Fund's concentration in technology securities presents
special risk considerations. Technology companies may produce or use products or
services that prove commercially unsuccessful, become obsolete or become
adversely impacted by government regulation. Competitive pressures in the
technology industry may affect negatively the financial condition of technology
companies, and the Fund's concentration in technology securities may subject it
to more volatile price movements than a more diversified securities portfolio.
In certain instances, technology securities may experience dramatic price
movements precipitated by investors' excessive optimism or pessimism with little
or no basis in fundamental economic conditions. As a result of these and other
reasons, investments in the technology industry can experience sudden and rapid
appreciation and depreciation. Investors should, therefore, expect that the net
asset value of the Fund's shares will be more volatile than, and may fluctuate
independently of, broad stock market indices such as the S&P 500.

         In addition, it is expected that more than 25% of the Technology Fund's
total assets will normally be invested in technology companies which develop or
sell computers, software and peripheral products. In addition to the risks
associated with other technology companies, these companies are often dependent
on the existence and health of other products or industries and face highly
competitive pressures, product licensing, trademark and patent uncertainties and
rapid technological changes which may have a significant effect on their
financial condition. For example, an increasing number of companies and new
product offerings can lead to price cuts and slower selling cycles, and many of
these companies may be dependent on the success of a principal product, may rely
on sole source providers and third-party manufacturers, and may experience
difficulties in managing growth.

         The Technology Fund may invest in the stocks of both large and small
companies. While Northern Trust believes that smaller companies can provide
greater growth potential than larger, more mature firms, investing in the
securities of small companies also involves greater risk and portfolio price
volatility as described above under "Investment Information -- Small Cap Fund."

INTERNATIONAL FUNDS -- FURTHER INFORMATION

The International Fixed Income, International Growth Equity and International
Select Equity Funds (the "International Funds") 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, Columbia,

                                      -31-
<PAGE>   42
Denmark, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia,
Ireland, Israel, Italy, Japan, Luxembourg, Malaysia, Mexico, the Netherlands,
New Zealand, Norway, the Philippines, Poland, Portugal, Peru, 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.

         Because the securities markets in the following countries are highly
developed, liquid and subject to extensive regulation, the International Growth
Equity and the International Select Equity Funds may invest more than 25% of
their respective total assets in the securities of issuers located in Japan and
the United Kingdom, and the International Fixed Income Fund may invest more than
25% of its total assets in the securities of issuers located in Canada, France,
Germany, Japan, the United Kingdom and the United States. Investment in a
particular country of 25% or more of a Fund's total assets will make a Fund'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. For example, efforts by the member countries of
the European Community to eliminate internal barriers to the free movement of
goods, persons, services and capital have encountered opposition arising from
the conflicting economic, political and cultural interests and traditions of the
member countries and their citizens. The reunification of the former German
Democratic Republic (East Germany) with the Federal Republic of Germany (West
Germany) and other political and social events in Europe have caused
considerable economic and social dislocations. Similarly, events in the Japanese
economy as well as social developments and natural disasters have affected
Japanese securities and currency markets, and have disrupted the relationship of
the Japanese yen with other currencies and with the U.S. dollar. Future
political, economic and social developments can be expected to produce
continuing effects on securities and currency markets. Investment in foreign
securities, including securities of issuers located in the countries listed
above, involves other risks which are described under "Additional Investment
Information, Risks and Considerations."

         Certain investments by the International Funds will involve risks
associated with investments in emerging market countries. In addition,
securities issued in certain countries are currently accessible to the
International Funds only through investment in other investment companies that
are specifically authorized to

                                      -32-
<PAGE>   43
invest in such securities. Further information about these matters is provided
under "Additional Investment Information, Risks and Considerations."

FUNDAMENTALS OF FIXED INCOME INVESTING

         Even though interest-bearing securities are investments which often
offer a stable stream of income, the prices of fixed income securities are
affected by changes in the prevailing level of interest rates. These securities
experience appreciation when interest rates decline and depreciation when
interest rates rise. A bond fund 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 Northern Trust
only as indicators of investment quality. For a more complete discussion of
ratings, see Appendix A to the Additional Statement.

ADDITIONAL INVESTMENT INFORMATION, RISKS AND CONSIDERATIONS

DESCRIPTION OF SECURITIES AND INVESTMENT TECHNIQUES

CONVERTIBLE SECURITIES. Each Equity Fund (other than the Stock Index Fund) and
the International Fixed Income Fund may invest in convertible securities
including convertible bonds, debentures, and preferred stock. A convertible
security 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 Fund seeks the opportunity, through the conversion
feature, to participate in a portion of 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 a Fund will usually be rated investment grade by S&P, Moody's, Duff or Fitch
or, if unrated, will be of comparable quality as determined by Northern Trust. A
Fund may, however, acquire convertible securities rated below investment grade
when Northern Trust believes that their investment characteristics make them
desirable, so long as (a) under normal market and economic conditions, less than
10% of the

                                      -33-
<PAGE>   44
Fund's total assets (35% in the case of the Income Equity Fund and 5% in the
case of the International Fixed Income Fund, International Growth Equity Fund
and International Select Equity Fund) are invested in non-investment grade
convertible securities and (b) any such security will be rated "B" or higher by
at least one major rating agency. As of March 31, 1996, the Income Equity Fund
had the following percentages of its portfolio assets invested in convertible
securities with the following ratings: 0.0% AAA, 3.9% AA, 16.8% A, 14.3% BBB,
8.5% BB, 10.1% B and 2.0% unrated. For a description of applicable securities
ratings, See Appendix A to the Additional Statement.

         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." Particular risks associated with lower-rated convertible
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 Fund'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 convertible 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 convertible security held by a Fund defaulted, the Fund could
incur additional expenses to seek recovery. Adverse publicity and investor
perceptions, whether or not based on fundamental analysis, may also decrease the
values and liquidity of lower-rated securities held by a Fund, especially in a
thinly traded market.

         For purposes of determining the percentage of Fund's assets that is
invested in equity securities, 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 remaining value will be deemed to be an equity
investment.

WARRANTS. Each Equity Fund (other than the Stock Index Fund) may invest up to 5%
of its net assets at the time of purchase in warrants and similar rights in
addition to those that have been acquired in units or are attached to other
securities). Warrants represent rights to purchase securities at a specific
price for a specific period of time. A Fund may also purchase bonds that are

                                      -34-
<PAGE>   45
issued in tandem with warrants entitling the holder to purchase common stock at
a specified price during a specified period. The prices of warrants do not
necessarily correlate with the prices of the underlying securities.

MUNICIPAL INSTRUMENTS. The Intermediate Tax-Exempt, Tax-Exempt, Florida
Intermediate Tax-Exempt, Municipal Money Market and California Municipal Money
Market Funds (the "Tax-Exempt Funds") intend to invest primarily in Municipal
Instruments. Municipal Instruments 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 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 tax or
other specific revenue source such as lease revenue 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 Funds 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 (if such a fund has been
established), the restoration of which is a moral commitment but not a legal
obligation of the state or municipality which created the issuer.

         Within the principal classifications of Municipal Instruments described
above there are a variety of categories, including municipal bonds, municipal
notes, municipal leases, custodial receipts and participation certificates.
Municipal notes include tax, revenue and bond anticipation notes of short
maturity, generally less than three years, which are issued to obtain temporary
funds for various public purposes. Municipal leases are obligations issued by
state and local governments or authorities to finance the acquisition of
equipment and facilities. Certain municipal lease obligations may include
"non-appropriation" clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated for such purpose on a yearly basis. Custodial receipts are
underwritten by securities dealers or banks and evidence ownership of future
interest payments, principal payments or both on certain

                                      -35-
<PAGE>   46
municipal securities. Participation certificates are obligations issued by state
or local governments or authorities to finance the acquisition of equipment and
facilities. They may represent participations in a lease, an installment
purchase contract, or a conditional sales contract. Municipal leases (and
participations in such leases) present the risk that a municipality will not
appropriate funds for the lease payments. Northern Trust, under the supervision
of Northern Funds' Board of Trustees, will determine the credit quality of any
unrated municipal leases on an ongoing basis, including an assessment of the
likelihood that the leases will not be cancelled.

         The Tax-Exempt Funds (other than the Municipal Money Market Fund and
California Municipal Money Market Fund) may also hold tax-exempt derivative
instruments that have interest rates that reset inversely to changing short-term
rates and/or have imbedded interest rate floors and caps that require the issuer
to pay an adjusted interest rate if market rates fall below or rise above a
specified rate. These derivative instruments represent beneficial interests in
Municipal Instruments that are marketed by investment banking firms under
various names such as FLOATs(SM), RITEs(SM), SAVRs(SM)and RIBs(SM). These 
instruments represent relatively recent innovations in the municipal bond
markets, and the trading market for these instruments is less developed than the
markets for traditional types of Municipal Instruments. It is uncertain how
these instruments will perform under different economic and interest-rate
scenarios. Because certain of these instruments are leveraged, their market
values may be more volatile than other types of Municipal Instruments and may
present greater potential for capital gain or loss. On the other hand, the
imbedded option features of other derivative instruments could limit the amount
of appreciation a Fund can realize on its investment, could cause a Fund to hold
a security it might otherwise sell or could force the sale of a security at
inopportune times or for prices that do not reflect current market value. The
possibility of default by the issuer or the issuer's credit provider may be
greater for these derivative instruments than for other types of instruments. In
some cases it may be difficult to determine the fair value of a derivative
instrument because of a lack of reliable objective information and an
established secondary market for some instruments may not exist. In many cases,
the Internal Revenue Service has not ruled on whether the interest received on a
tax-exempt derivative instrument is tax-exempt and, accordingly, purchases of
such instruments are based on the opinion of counsel to the sponsors of the
instruments. Neither the Funds nor Northern Trust will review the Municipal,
Corporate or other proceedings related to the creation of any tax-exempt
derivatives or the basis for such opinions.


                                      -36-
<PAGE>   47
         Each Tax-Exempt Fund may acquire "stand-by commitments" relating to the
Municipal Instruments it holds. Under a standby commitment, a dealer agrees to
purchase, at the Fund's option, specified Municipal Instruments at a specified
price. A stand-by commitment may increase the cost, and thereby reduce the
yield, of the Municipal Instruments to which the commitment relates. The Funds
will acquire stand-by commitments solely to facilitate portfolio liquidity and
do not intend to exercise their rights for trading purposes.

         Municipal Instruments purchased by the Tax-Exempt Funds may be backed
by letters of credit or other forms of credit enhancement issued by domestic or
foreign banks and other financial institutions. The credit quality of these
banks and financial institutions could, therefore, cause loss to a Fund that
invests in Municipal Instruments and affect its share price. Foreign letters of
credit may involve certain risks in addition to those of domestic obligations.
Foreign banks and foreign branches of domestic banks may be subject to less
stringent reserve requirements, and to different accounting, auditing and
recordkeeping requirements than domestic banks.

         The Tax-Exempt Funds do not intend to invest 25% or more of the value
of their respective 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. Each
Fund may, however, invest 25% or more of its total assets in Municipal
Instruments the interest on which is paid solely from revenues of similar
projects. In addition, although the Funds, other than the Florida Intermediate
Tax-Exempt Fund and the California Municipal Money Market Fund, do not expect to
do so during normal market conditions, each may invest more than 25% of the
value of its total assets in Municipal Instruments whose issuers are in the same
state. The Florida Intermediate Tax-Exempt Fund expects to invest principally
in Florida Municipal Instruments and the California Municipal Money Market Fund
expects to invest principally in California Municipal Instruments. When a
substantial portion of a Fund'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 instrument would
likewise affect the related instruments.

         Funds in addition to the Tax-Exempt Funds may invest from time to time
in Municipal Instruments or other securities issued by state and local
governmental bodies when Northern Trust believes such an investment strategy is
in the best interest of Northern Funds' shareholders. Dividends paid by Funds
other than the Tax-Exempt Funds on such investments will be taxable to
shareholders.

FOREIGN SECURITIES. The International Funds intend to invest primarily in the
securities of foreign issuers. In addition, each Equity Fund and the Fixed
Income Fund may invest a portion of their assets in such securities, including
(except with respect to the Fixed Income Fund) eurodollar convertible
securities, which are fixed income securities that are issued in U.S. dollars
outside the United States and are convertible into or exchangeable for equity
securities of the same or a different issuer. The Money Market Fund may also
invest in dollar-denominated obligations issued or guaranteed by one or more
foreign governments or any of their political subdivisions, agencies or
instrumentalities. These obligations may be issued by supranational entities,
including international organizations (such as the European Coal and Steel
Community) designated or supported by governmental entities to promote economic
reconstruction or development and international banking institutions and related
government agencies.

         Investment in foreign securities involves special risks. These include
market risk, interest rate risk and the risks of investing in securities of
foreign issuers and of companies whose securities are principally traded outside
the United States and in investments denominated in foreign currencies. Market
risk involves the possibility that stock prices will decline over short or even
extended periods. The stock markets tend to be cyclical, with periods of
generally rising prices and periods of generally declining prices. These cycles
will affect the value of a Fund that invests in foreign stocks. The holdings of
a Fund that invest in fixed income securities will be sensitive to changes in
interest rates and the interest rate environment. Generally, the prices of bonds
and debt securities fluctuate inversely with interest rate changes. In addition,
the performance of investments in securities denominated in a foreign currency
will depend 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.

         There are other risks and costs involved in investing in foreign
securities which are in addition to the usual risks inherent in domestic
investments. Investment in foreign securities 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 also involve risks associated

                                      -38-
<PAGE>   49
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 the
adoption of other governmental restrictions might adversely affect an investment
in foreign securities. Additionally, foreign banks and foreign branches of
domestic banks are subject to less stringent reserve requirements, and to
different accounting, auditing and recordkeeping requirements.

         The Money Market Fund, the Fixed Income Fund, each Equity Fund and each
International Fund may invest in foreign debt, or the securities of foreign
governments. Several risks exist concerning such investments, 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.

         In addition, the International Funds may invest their assets 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 of such countries may be
undergoing significant evolution and rapid development, and such countries may
lack the social, political and economic stability characteristic of more
developed countries. Some of these countries may have in the past failed to
recognize private property rights and have at times nationalized or expropriated
the assets of private companies. As a result, the risks described above,
including the risks of nationalization or expropriation of assets, may be
heightened. In addition, unanticipated political or social developments may
affect the values of a Fund's investments in those countries and the
availability to a Fund 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 Fund's
investments in such countries illiquid and more volatile than investments in
Japan or most Western European countries, and a Fund 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.

         Although a Fund (other than the Money Market Fund) may invest in
securities denominated in foreign currencies, its

                                      -39-
<PAGE>   50
portfolio securities and other assets are valued in U.S. dollars. Currency
exchange rates may fluctuate significantly over short periods of time causing,
together with other factors, a Fund'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. To the extent
that a Fund's total assets, adjusted to reflect the Fund's net position after
giving effect to currency transactions, are denominated in the currencies of
foreign countries, the Fund will be more susceptible to the risk of adverse
economic and political developments within those countries. In addition, through
the use of forward currency exchange contracts and other instruments, the
respective net currency positions of the International Funds may expose them to
risks independent of their securities positions. Although the net long and short
foreign currency exposure of the International Funds will not exceed their
respective total asset values, to the extent that a Fund is fully invested in
foreign securities while also maintaining currency positions, it may be exposed
to greater risk than it would have if it did not maintain the currency
positions. The Funds are also subject to the possible imposition of exchange
control regulations or freezes on convertibility of currency.

         The International Fixed Income Fund may 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 Ministers of the European
Community from time to time to reflect changes in relative values of the
underlying currencies. The Fund may also invest in securities denominated in
other currency "baskets."

         Investors should understand that the expense ratios of the
International Funds can be expected to be higher than those of 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.

         Dividends and interest payable on a Fund's foreign portfolio securities
may be subject to foreign withholding taxes. To the extent such taxes are not
offset by credits or deductions allowed to investors under U.S. federal income
tax law, they may reduce the net return to the shareholders. See "Distributions
and Taxes."


                                      -40-

AMERICAN DEPOSITORY RECEIPTS. Each Equity Fund (other than the Stock Index Fund)
and each International Fund can invest in ADRs. 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. Some
institutions issuing ADRs 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.

EUROPEAN DEPOSITORY RECEIPTS. Each Equity Fund (other than the Stock Index Fund)
and each International Fund can also invest in EDRs. EDRs are receipts issued by
a European financial institution evidencing ownership of underlying foreign
securities and are usually denominated in foreign currencies. EDRs may not be
denominated in the same currency as the securities they represent. Generally,
EDRs, in bearer form, are designed for use in the European securities markets.

FORWARD CURRENCY EXCHANGE CONTRACTS. The Equity Funds (other than the Stock
Index Fund), the International Funds and the Fixed Income Fund may enter into
forward currency exchange contracts in an effort to hedge all or any portion of
their portfolio positions. Specifically, foreign currency contracts may be used
for this purpose to reduce the level of volatility caused by changes in foreign
currency exchange rates or when such transactions are economically appropriate
for the reduction of risks in the ongoing management of the Fund. The
International Funds may also enter into foreign currency exchange contracts to
seek to increase total return when Northern Trust anticipates that a foreign
currency will appreciate or depreciate in value, but securities denominated in
that currency do not in Northern Trust's view present attractive investment
opportunities and are not held by the Fund. In addition, the International Funds
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 Trust 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 these contracts may be used 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 Fund may choose to refrain from entering into
such contracts. In connection with its forward currency exchange contracts, a
Fund will create a segregated account of liquid assets, such as cash,

                                      -41-
<PAGE>   52
U.S. Government securities or other liquid securities, or will otherwise cover
its position in accordance with applicable requirements of the SEC.

OPTIONS AND FUTURES CONTRACTS. To the extent consistent with its investment
objective, each Fund (other than the Money Market Funds) may write covered call
options, buy put options, buy call options and write secured put options for the
purpose of hedging or earning additional income, which may be deemed speculative
or, with respect to the International Funds, cross-hedging. These options may
relate to particular securities, financial instruments, foreign currencies,
stock or bond indices or (in the case of the International Fixed Income Fund)
the yield differential between two securities, and may or may not be listed on a
securities exchange and may or may not be issued by the Options Clearing
Corporation. A Fund will not purchase put and call options where the aggregate
premiums on outstanding options exceed 5% of its net assets at the time of
purchase, and will not write options on more than 25% of the value of its net
assets (measured at the time an option is written). Options trading is a highly
specialized activity that entails greater than ordinary investment risks. In
addition, unlisted options are not subject to the protections afforded
purchasers of listed options issued by the Options Clearing Corporation, which
performs the obligations of its members if they default.

         To the extent consistent with its investment objective, each Fund
(other than the Money Market Funds) may also invest in futures contracts and
options on futures contracts for hedging purposes or to maintain liquidity to
meet potential shareholder redemptions, invest cash balances or dividends or
minimize trading costs. The value of a Fund's futures contracts may equal or
exceed 100% of the Fund's total assets, although a Fund will not purchase or
sell a futures contract unless immediately afterwards the aggregate amount of
margin deposits on its existing futures positions plus the amount of premiums
paid for related futures options is 5% or less of its net assets.

         Futures contracts obligate a Fund, at maturity, to take or make
delivery of certain securities, the cash value of a securities index or a stated
quantity of a foreign currency. A Fund may sell a futures contract in order to
offset an expected decrease in the value of its portfolio that might otherwise
result from a market decline or currency exchange fluctuation. A Fund may do so
either to hedge the value of its securities portfolio as a whole, or to protect
against declines occurring prior to sales of securities in the value of the
securities to be sold. In addition, a Fund may utilize futures contracts in
anticipation of changes in the composition of its holdings or in currency
exchange rates.


                                      -42-
<PAGE>   53
         A Fund may purchase and sell call and put options on futures contracts
traded on an exchange or board of trade. When a Fund purchases an option on a
futures contract, it has the right to assume a position as a purchaser or a
seller of a futures contract at a specified exercise price anytime during the
option period. When a Fund sells an option on a futures contract, it becomes
obligated to sell or buy a futures contract if the option is exercised. In
connection with a Fund's position in a futures contract or related option, the
Fund will create a segregated account of liquid high-grade assets or will
otherwise cover its position in accordance with applicable SEC requirements.

         The primary risks associated with the use of futures contracts and
options are: (a) the imperfect correlation between the change in market value of
the instruments held by a Fund and the price of the futures contract or option;
(b) possible lack of a liquid secondary market for a futures contract and the
resulting inability to close a futures contract when desired; (c) losses caused
by unanticipated market movements, which are potentially unlimited; and (d)
Northern Trust's ability to predict correctly the direction of securities
prices, interest rates, currency exchange rates and other economic factors. For
further discussion of risks involved with domestic and foreign futures and
options, see "Futures Contracts and Related Options" and Appendix B in the
Additional Statement.

         Northern Funds intends to comply with the regulations of the Commodity
Futures Trading Commission exempting the Funds from registration as a "commodity
pool operator."

INTEREST RATE AND CURRENCY SWAPS. In order to protect their value from interest
rate fluctuations, the U.S. Government, Fixed Income, Intermediate Tax-Exempt,
Tax-Exempt, Florida Intermediate Tax-Exempt, International Fixed Income and
Income Equity Funds may enter into interest rate swaps. The Funds expect to
enter into interest rate swaps primarily to preserve a return or spread of a
particular investment or portion of their respective holdings and to protect
against an increase in the price of securities the Funds anticipate purchasing
at a later date. Interest rate swaps involve the exchange by a Fund with another
party of their respective commitments to pay or receive interest (e.g., an
exchange of floating rate payments for fixed rate payments). In order to protect
against currency fluctuations, the International Funds may also enter into
currency swaps. Currency swaps involve the exchange of the rights of a Fund and
another party to make or receive payments in specified currencies.

         The net amount of the excess, if any, of a Fund's obligations over its
entitlements with respect to each interest rate or currency swap will be accrued
on a daily basis and an amount of liquid assets, such as cash, U.S. Government
securities

                                      -43-
<PAGE>   54
or other liquid high grade debt securities, having an aggregate net asset value
at least equal to such accrued excess will be maintained in a segregated account
by Northern Funds' custodian. A Fund will not enter into any interest rate or
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.

UNITED STATES GOVERNMENT OBLIGATIONS. To the extent consistent with their
respective investment objectives, the Funds 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. The Funds
may also invest in other securities issued or guaranteed by the U.S. Government,
its agencies or instrumentalities. 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, such as those of the Student Loan Marketing
Association ("SLMA"), 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. Obligations of the International Bank for Reconstruction and Development
(also known as the World Bank) are supported by subscribed, but unpaid,
commitments of its member countries. 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. 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.

STRIPPED OBLIGATIONS. To the extent consistent with their respective investment
objectives, the Funds 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

                                      -44-
<PAGE>   55
U.S. Government (or a U.S. Government agency or instrumentality), foreign
governments or private issuers such as banks and other 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.

         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 cases, 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 Fund may fail to fully recoup its
initial investment. The market value of the class consisting entirely of
principal payments can be 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
greater 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
Northern Funds' 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 a Fund's per share net asset value.

CUSTODIAL RECEIPTS FOR TREASURY SECURITIES. To the extent consistent with their
respective investment objectives, the Funds, other than the U.S. Government
Select Money Market Fund may also purchase participations in trusts that hold
U.S. Treasury securities (such as TIGRs and CATS) or other obligations where the
trust participations evidence ownership in either the future interest payments
or the future principal payments on the obligations. Like other stripped
obligations, these participations are also normally issued at a discount to
their "face value," and can exhibit greater price volatility than ordinary debt
securities because of the way in which their principal and interest are returned
to investors. Investments by the U.S. Government Money Market Fund in such
participations will not exceed 35% of the value of that Fund's total assets.

ASSET-BACKED SECURITIES. The U.S. Government Fund and U.S. Government Money
Market Fund may purchase securities that are

                                      -45-
<PAGE>   56
secured or backed by mortgages and that are issued by the U.S. Government, its
agencies or instrumentalities. The other Funds 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 the U.S. Government, GNMA, FNMA, Federal Home Loan Mortgage
Corporation, and private issuers such as commercial banks, financial companies,
finance subsidiaries of industrial companies, savings and loan associations,
mortgage banks, investment banks and certain special purpose entities. The Funds
will not purchase non-mortgage asset-backed securities that are not rated
investment grade by S&P, Duff, Fitch or Moody's.

         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.

         The Funds may acquire several types of mortgage-backed securities,
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 relative payment
rights of the various CMO classes may be structured in a variety of ways. The
Funds 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

                                      -46-
<PAGE>   57
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 a Fund (other than a Money Market
Fund), 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.

CORPORATE AND BANK OBLIGATIONS. To the extent consistent with their respective
investment objectives, the Funds, other than the U.S. Government Select Money
Market Fund, may invest in debt obligations of domestic or foreign corporations
and banks, and 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. Bank obligations may include certificates of deposit, notes, bankers'
acceptances and fixed time deposits. These obligations may be general
obligations of the parent bank or may be limited to the issuing branch or
subsidiary by the terms of specific obligation or by government regulation. For
purposes of determining the permissibility of an investment in bank obligations,
the total assets of a bank are determined on the basis of the bank's most recent
annual financial statements.

EXCHANGE RATE-RELATED SECURITIES. The Income Equity, International Fixed Income
and Fixed Income Funds may each 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

                                      -47-
<PAGE>   58
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, there is no assurance that sufficient trading interest
to create a liquid secondary market will exist for a particular Exchange
Rate-Related Security due to conditions in the debt and foreign currency
markets. Illiquidity in the forward foreign 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 Fixed Income Fund and the Money Market Fund
may make limited investments in guaranteed investment contracts ("GICs") issued
by highly rated U.S. and foreign insurance companies. Pursuant to these
contracts, a Fund makes cash contributions to a deposit fund of the insurance
company's general account. The insurance company then credits to the Fund, on a
monthly basis, interest which is based on an index (such as the Salomon Brothers
CD Index), but is guaranteed not to be less than a certain minimum rate. The
Money Market Fund and Fixed Income Fund 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 Trust. 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 normally be considered illiquid investments, and
will be acquired subject to the limitation on illiquid investments.

VARIABLE AND FLOATING RATE INSTRUMENTS. In accordance with their respective
investment objectives, the Funds may purchase rated and unrated variable and
floating rate instruments. These instruments may include variable amount master
demand notes that permit the indebtedness to vary in addition to providing for
periodic adjustments in the interest rate. A Fund may purchase variable and
floating rate instruments with stated maturities in excess of its maturity
limitations provided that the Fund may demand payment of the principal of the
instrument at least once within the applicable maturity limitation on not more
than thirty days' notice (unless the instrument is issued or guaranteed by the
U.S. Government or an agency or instrumentality thereof). Unrated instruments
will be determined by Northern Trust to be of comparable quality at the time of
purchase to rated instruments purchasable by the Funds.


                                      -48-
<PAGE>   59
         The Funds (other than the Money Market Funds) may also invest in
leveraged inverse floating rate debt instruments ("inverse floaters"). The
interest rate of an inverse floater resets in the opposite direction from the
market rate of interest to which it 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.

         The absence of an active secondary market with respect to particular
variable and floating rate instruments could make it difficult for a Fund to
dispose of the instruments if the issuer defaulted on its payment obligation or
during periods that the Fund is not entitled to exercise demand rights, and a
Fund could, for these or other reasons, suffer a loss with respect to such
instruments. Variable and floating rate instruments (including inverse floaters)
will be subject to a Fund's limitation on illiquid investments when the Fund may
not demand payment of the principal amount within seven days and a reliable
trading market is absent. See "Illiquid Securities."

REPURCHASE AGREEMENTS. Each Fund may 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 one
year, settlement for the repurchase agreement will never be more than one year
after a Fund's acquisition of the securities and normally will be within a
shorter period of time. Securities subject to repurchase agreements are held
either by Northern Funds' 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 Fund to possible loss because of adverse
market action or delay in connection with the disposition of the underlying
obligations.

REVERSE REPURCHASE AGREEMENTS AND OTHER BORROWINGS. Each Fund is authorized to
make limited borrowings as described below under "Investment Restrictions." If
the securities held by a Fund should decline in value while borrowings are
outstanding, the market value of the Fund's portfolio will decline
proportionately more than the decline in value it would otherwise suffer.
Borrowings may be made through reverse repurchase agreements under which a Fund
sells portfolio securities to financial institutions such as banks and
broker/dealers and agrees to repurchase them at a particular date and price. The
Funds may use the proceeds of reverse repurchase agreements to purchase

                                      -49-
<PAGE>   60
other securities either maturing, or under an agreement to resell, on a date
simultaneous with or prior to the expiration of the reverse repurchase
agreement. The Funds (other than the Municipal Money Market, U.S. Government
Select Money Market, California Municipal Money Market, Income Equity, Growth
Equity, Select Equity and Small Cap Funds) 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 transaction. This use of reverse repurchase agreements may be
regarded as leveraging and, therefore, speculative. Reverse repurchase
agreements involve the risks that the interest income earned in the investment
of the proceeds will be less than the interest expense, that the market value of
the securities sold by a Fund may decline below the price of the securities the
Fund is obligated to repurchase and that the securities may not be returned to
the Fund. During the time a reverse repurchase agreement is outstanding, a Fund
will maintain a segregated account with Northern Funds' custodian containing
cash, U.S. Government or other appropriate liquid securities having a value at
least equal to the repurchase price. A Fund's reverse repurchase agreements,
together with any other borrowings, will not exceed, in the aggregate, 33 1/3%
of the value of its total assets. In addition, whenever borrowings exceed 5% of
the Fund's total assets, the Fund will not make any investments.

SECURITIES LENDING. Each Fund may seek additional income from time to time by
lending securities on a short-term basis to banks, brokers and dealers. The
securities lending agreements will require that the loans be secured by
collateral in 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 loaned securities. A Fund may not make such loans in
excess of 33 1/3% of the value of its total assets. Securities loans involve
risks of delay in receiving additional collateral or in recovering the loaned
securities, or possibly loss of rights in the collateral if the borrower of the
securities becomes insolvent.

FORWARD COMMITMENTS, WHEN-ISSUED SECURITIES AND DELAYED-DELIVERY TRANSACTIONS.
Each Fund may purchase or sell securities on a when-issued or delayed-delivery
basis and make contracts to purchase or sell securities for a fixed price at a
future date beyond customary settlement time. Securities purchased or sold 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, or the value of the
security to be sold increases, before the settlement date. Although a Fund will
generally purchase securities with the intention of acquiring them, a Fund may
dispose of securities purchased on a when-issued, delayed-delivery or a forward
commitment basis before settlement when deemed appropriate by Northern Trust.

                                      -50-
<PAGE>   61
INVESTMENT COMPANIES. In connection with the management of its daily cash
positions, each Fund 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. In addition, each Fund may invest in
securities issued by other investment companies if otherwise consistent with its
investment objectives and policies which, with respect to the International
Funds, includes shares of investment companies investing primarily in foreign
securities, including so-called "country funds." Country funds have portfolios
consisting exclusively of securities of issuers located in one or more specified
foreign countries. As a shareholder of another investment company, a Fund will
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 Fund bears directly in
connection with its own operations. Investments in other investment companies
will be subject to the limits imposed by the 1940 Act.

ILLIQUID SECURITIES. Each Fund may invest up to 15% (10% in the case of the
Money Market Funds) of the value of its net assets in illiquid securities.
Illiquid securities generally include repurchase agreements and time deposits
with notice/termination dates in excess of seven days, SMBS issued by private
issuers, interest rate and currency swaps, unlisted over-the-counter options,
GICs 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 its investment objective and policies,
each Fund 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
Trust determines, under guidelines approved by Northern Funds' 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. The ability to sell to
qualified institutional buyers under Rule 144A is a relatively recent
development, and it is not possible to predict how this market will ultimately
develop.

PORTFOLIO TRANSACTIONS AND TURNOVER. Northern Trust's Advisory Agreement
provides that in selecting brokers or dealers to place orders for transactions
(a) involving common and preferred stocks, Northern Trust shall use its best
judgment to obtain the best overall terms available and (b) involving bonds and
other fixed income obligations, Northern Trust shall attempt to obtain

                                      -51-
<PAGE>   62
best net price and execution. In assessing the best overall terms available for
any transaction, Northern Trust is to consider all factors it deems 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, Northern
Trust may consider the brokerage and research services provided to the Funds
and/or other accounts over which Northern Trust or an affiliate of Northern
Trust exercises 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.

         The portfolio turnover rates of the Funds will vary from year to year,
and may be affected by changes in country and currency weightings, as well as
changes in the holdings of specific issuers. Investments in issuers in smaller
or emerging markets may also contribute to portfolio turnover for the
International Funds. High portfolio turnover (100% or more) may result in the
realization of short-term capital gains which are taxable to shareholders as
ordinary income. In addition, higher turnover rates can result in corresponding
increases in commissions and other transaction costs. Northern Trust will not
consider turnover rate a limiting factor in making investment decisions. The
portfolio turnover rates of each Fund (other than the Money Market Funds and the
Florida Intermediate Tax-Exempt Fund, Stock Index Fund and Technology Fund) for
Northern Funds' fiscal year ended March 31, 1996 are stated under "Financial
Highlights." Northern Funds expects that the annual turnover rate of the Florida
Intermediate Tax-Exempt Fund, Technology Fund and Stock Index Fund will
generally not exceed 100%, 150% and 100%, respectively.

MISCELLANEOUS. After its purchase by a Fund, a rated security may cease to be
rated or its rating may be reduced below the minimum rating required for
purchase by the Fund. Northern Trust will consider such an event in determining
whether the Fund should continue to hold the security. Except for the
convertible securities described above, Northern Trust expects to sell promptly
any securities that are non-investment grade which exceed 5% of a Fund's net
assets, or are below "high quality" in the case of the Money Market Funds, where
it has determined that such sale is in the best interest of the Fund.

         For a description of applicable securities ratings, see Appendix A to
the Additional Statement. Investment grade securities rated BBB by S&P, Duff or
Fitch, or Baa by Moody's have certain speculative characteristics and changes in
economic

                                      -52-
<PAGE>   63
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.

         The Funds do not intend to purchase certificates of deposit of Northern
Trust or its affiliate banks, commercial paper issued by Northern Trust's parent
holding company or other securities issued or guaranteed by Northern Trust, its
parent holding company or their subsidiaries or affiliates.

INVESTMENT RESTRICTIONS

A Fund's investment objective may be changed by Northern Funds' Board of
Trustees without shareholder approval. Shareholders will, however, be notified
of any changes. Any such change may result in a Fund having an investment
objective different from the objective which the shareholder considered
appropriate at the time of investment in the Fund. No assurance can be provided
that a Fund will achieve its investment objective.

         Each Fund has also adopted certain fundamental investment restrictions
that may be changed only with the approval of a majority of a Fund's outstanding
shares. The following description summarizes several of the Funds' fundamental
restrictions, which are set forth in full in the Additional Statement.

         No Fund may:

         1. invest 25% or more of its total assets at the time of purchase in
securities of issuers whose principal business activities are in the same
industry (a) with certain limited exceptions set forth in the Additional
Statement and (b) except that the Technology Fund may not invest less than 25%
of its assets at the time of purchase in the securities of issuers principally
engaged in technology business activities, other than during temporary defensive
periods;

         2. borrow money except in amounts up to 33 1/3% of the value of its
total assets at the time of borrowing.

         3. purchase securities (except U.S. Government securities and
repurchase agreements collateralized by such securities) if more than 5% of its
total assets at the time of purchase will be invested in the securities of any
one issuer, except that up to 25% (50% for the California Municipal Money Market
Fund) of a Fund's total assets may be invested without regard to this 5%
limitation; or

         4. subject to the foregoing 25% exception, purchase more than 10% of
the outstanding voting securities of any issuer.


                                      -53-
<PAGE>   64
         Restrictions 3 and 4 do not apply to the Florida Intermediate
Tax-Exempt Fund or the International Fixed Income Fund. Instead, as a
non-fundamental investment restriction, the Florida Intermediate Tax-Exempt Fund
and International Fixed Income Fund will not hold any securities (except U.S.
Government securities and repurchase agreements collateralized by such
securities) that would cause, at the end of any tax quarter, more than 5% of
their respective total assets to be invested in the securities of any one
issuer, except that up to 50% of the respective Fund's total assets may be
invested without regard to this limitation so long as no more than 25% of the
Fund's total assets are invested in any one issuer (except the U.S. Government,
its agencies and instrumentalities).

         In accordance with current SEC regulations (which are more restrictive
than the Funds' fundamental investment restrictions), the Money Market, U.S.
Government Money Market, U.S. Government Select Money Market, Municipal Money
Market and California Municipal Money Market Funds intend, as a non-fundamental
policy, to limit investments in the securities of any single issuer (other than
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities and repurchase agreements collateralized by such securities)
to not more than 5% of the value of their respective total assets at the time of
purchase, except that (a) 25% of the value of the total assets of the California
Municipal Money Market Fund may be invested in fewer than five issuers; (b) 25%
of the value of the total assets of the other Money Market Funds may be invested
in any one issuer for a period of up to three Business Days; and (c) securities
subject to certain unconditional demand features are subject to different
diversification requirements as described in the Additional Statement. In
addition, the Money Market, U.S. Government Money Market and U.S. Government
Select Money Market Funds will limit their investments in all securities, and
the Municipal Money Market and California Municipal Money Market Funds will
limit their investments in certain conduit securities as described in the
Additional Statement, that are not in the highest 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, to 5% of their total assets, with
investments in any one such issuer being limited to no more than 1% of its total
assets or $1 million, whichever is greater, measured at the time of purchase.


OPENING AN ACCOUNT AND PURCHASING SHARES

         An investment account may be opened and shares purchased directly from
Northern Funds by following the instructions below under "Purchasing Shares
Directly from the Funds." If you maintain certain accounts at Northern Trust or
another institution (such as a bank or broker/dealer) that has entered

                                      -54-
<PAGE>   65
into an agreement with Northern Funds to provide services to its customers, you
may purchase shares through your institution in accordance with its procedures.
See "Purchasing Shares Through Northern Trust and Other Institutions" below for
more details. If you have any questions or need any assistance in opening an
investment account or purchasing shares, call 1-800-595-9111.

         The Stock Index Fund will not commence investment operations until it
has received orders for the purchase of its shares aggregating $5 million, and
will not accept payment for the purchase of shares until orders in this
aggregate amount are received. Northern Trust anticipates that the Stock Index
fund will commence operations in the Fall of 1996.

PURCHASING SHARES DIRECTLY FROM THE FUNDS

         For your convenience, there are a number of ways to invest directly
with Northern Funds. When establishing an investment account directly with
Northern Funds, the minimum initial investment in a Fund is $2,500 ($500 for an
IRA; $250 for a spousal IRA; $250 under the Automatic Investment Plan; and $500
for employees of the Northern Trust and its affiliates). The minimum subsequent
investment is $50 (except for reinvestments of distributions for which there is
no minimum). The Funds reserve the right to waive these minimums.

BY MAIL. You may purchase shares by mail by sending a Purchase Application, a
copy of which accompanies this Prospectus, together with a check or money order
payable to Northern Funds in the envelope provided or by addressing your
envelope to Northern Funds at P.O. Box 75986, Chicago, Illinois 60690-6319.
Additional requirements may be imposed. If using overnight delivery use the
following address: 801 South Canal Street, Chicago, Illinois 60607, Attn:
Northern Funds. Your check must be drawn on a bank located in the U.S. and must
be payable in U.S. dollars. When making subsequent investments, enclose your
check with the return remittance portion of the confirmation of your previous
investment, or indicate on your check or a separate piece of paper your name,
address and account number.

         A $20 fee will be charged by the Transfer Agent if any check used for
investment does not clear. In addition, you will be responsible for any loss
suffered by a Fund. If you purchase shares by check and subsequently request the
redemption of those shares, Northern Funds may delay the payment of redemption
proceeds until the Transfer Agent is satisfied that the check has cleared, which
may take up to 15 days from the purchase date. If you anticipate redemptions
soon after purchase, you may wish to wire funds to avoid delays. Northern Funds
will not accept payment in cash or third party checks for the purchase of
shares.


                                      -55-
<PAGE>   66
BY WIRE. You may make initial or subsequent investments in shares of the Funds
by wiring federal funds. If you are opening an account with a wire purchase, you
must call 1-800-595-9111 for instructions prior to wiring funds. You must
promptly complete a Purchase Application and forward it to the Transfer Agent in
the envelope provided herewith, or by addressing your envelope to Northern Funds
at P.O. Box 75986, Chicago, Illinois 60690-6319. Additional requirements may be
imposed. Redemptions will not be paid until your completed application has been
received by the Transfer Agent. If you wish to add to an existing account by
wire purchase, you may wire federal funds to:

                  The Northern Trust Company
                  Chicago, Illinois
                  ABA Routing No.  0710-00152,
                  (Reference 10 Digit Fund Account Number)
                  (Reference Shareholder's Name)

DIRECT DEPOSIT. You may purchase additional shares through the Direct Payroll
Deposit Plan offered by Northern Funds. Through this plan, periodic investments
(minimum $50) are made automatically from your payroll check into your existing
Fund account. In order to participate in the plan, your employer must have
direct deposit capabilities through the Automated Clearing House ("ACH")
available to its employees. The plan may be used for other direct deposits, such
as social security checks, military allotments, and annuity payments. Further
details about this service may be obtained from the Transfer Agent by calling
1-800-595-9111. Northern Funds reserves the right, at any time and without prior
notice, to limit or terminate the Direct Payroll Deposit privilege or its use in
any manner by any person.

AUTOMATIC INVESTMENT. Northern Funds offers an Automatic Investment Plan that
allows you to automatically purchase shares on a regular, monthly basis ($250
initial minimum, $50 monthly minimum additions). Under this plan the Transfer
Agent originates an ACH request to your financial institution which forwards
funds periodically to the Transfer Agent to purchase shares. The plan can be
established with any financial institution that participates in the ACH funds
transfer system. No service fee is currently charged by Northern Funds for
participation in the plan. You may establish the plan by completing the
appropriate section on the Purchase Application when opening an account. You may
also establish the plan after an account is opened by completing an Automatic
Investment Plan Application which may be obtained by calling 1-800-595-9111. If
an investor discontinues participation in the plan, the Funds reserve the right
to redeem the investor's account involuntarily, upon 60 days' written notice, if
the account's net asset value is $1,000 or less.


                                      -56-
<PAGE>   67
DIRECTED REINVESTMENTS. In addition to having your income dividends and/or
capital gains distributions reinvested in shares of the Fund from which such
distributions are paid, you may elect the directed reinvestment option and have
dividends and capital gains distributions automatically invested in another
Northern Fund. In addition, systematic withdrawals from one account and
reinvestments in another account may be established. See "Redeeming and
Exchanging Directly from the Funds -- Systematic Withdrawals." Reinvestments can
only be directed to an existing Northern Funds' account (which must meet the
minimum investment requirement). Directed reinvestments may be used to invest
funds from a regular account to another regular account, from a qualified plan
account to another qualified plan account, or from a qualified plan account to a
regular account. Directed reinvestments from a qualified plan account to a
regular account may have adverse tax consequences including imposition of a
penalty tax and therefore you should consult your own tax adviser before
commencing these transactions.

BY EXCHANGE. You may open a new account or add to an existing account by
exchanging shares of one Fund for shares of any other Fund offered by Northern
Funds. See "Redeeming and Exchanging Shares" for details.

PURCHASING SHARES THROUGH NORTHERN TRUST AND OTHER INSTITUTIONS

Northern Trust customers may purchase shares through their qualified accounts
and should consult with their account officer for additional information and
instructions. Customers of other institutions (together with Northern Trust,
"Service Organizations"), such as banks or broker-dealers that have entered into
agreements with Northern Funds, should contact their account officers for
appropriate purchase instructions. Northern Trust or another Service
Organization may impose particular customer account requirements in connection
with investments in the Funds, such as minimum account size or minimum account
thresholds above which excess cash balances may be invested in Fund shares. To
determine whether you may purchase shares through your institution, contact your
institution directly or call 1-800-595-9111. Purchases (and redemptions) placed
through Northern Trust or another Service Organization are processed only on
days that both Northern Funds and the particular institution are open for
business.

         Depending on the terms of the particular account used to purchase Fund
shares, Northern Trust or other institutions may impose charges against the
account. These charges could include asset allocation fees, account maintenance
fees, sweep fees, compensating balance requirements or other charges based upon
account transactions, assets or income. The charges will reduce the net return
on an investment in a Fund. For further discussion of Service Organizations and
the procedures for

                                      -57-

purchasing (and redeeming) shares through them, see "Management -- Service
Organizations."

ADDITIONAL PURCHASE INFORMATION

EFFECTIVE TIME AND PRICE OF PURCHASES -- NON-MONEY MARKET FUNDS. A purchase
order for Fund shares received by the Transfer Agent by 3:00 p.m. (Chicago Time)
on a Business Day (as defined below under "Further Information --
Miscellaneous") will be priced at the net asset value determined on that day,
provided that either: (a) the order is accompanied by payment of the purchase
price; or (b) the order is placed by Northern Trust or a Service Organization
that is acting on behalf of itself or its qualified customer accounts and
undertakes to make payment on the next Business Day in the form of federal funds
or other immediately available funds. If an order in proper form with proper
payment is not received by the Transfer Agent by such time, the order will be
processed at the next determined net asset value after the Transfer Agent has
received both an order in proper form and such payment.

EFFECTIVE TIME AND PRICE OF PURCHASES -- MONEY MARKET FUNDS. A purchase order
for Fund shares received by the Transfer Agent by 1:00 p.m. (Chicago Time) on a
Business Day will be executed that day, provided immediately available funds
have been received by the Transfer Agent by that time. If your purchase order or
immediately available funds are not received by the Transfer Agent by 1:00 p.m.
(Chicago Time), then your purchase order will be executed on the next Business
Day following the Business Day on which your order and immediately available
funds are received by the Transfer Agent. Purchase orders that are accompanied
by payment in any form other than immediately available funds will be executed
on the next Business Day after the Business Day on which both the order and
payment in proper form are received by the Transfer Agent.

MISCELLANEOUS PURCHASE INFORMATION. You will be responsible for all losses and
expenses of the Funds as a result of a check that does not clear or an ACH
transfer that is rejected. Northern Funds may decline to accept a purchase order
when, in the judgment of Northern Funds or its investment adviser, it would not
be in the best interest of existing shareholders to accept the order. Federal
regulations require that you provide a social security number or other certified
taxpayer identification number upon opening or reopening an account. Purchase
Applications 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 60 days of the date of the Purchase
Application. Payment for shares of a Fund may, in the discretion of Northern
Trust, be made in the form of securities that are permissible investments for
the respective Fund. For further information, see the Additional

                                      -58-
<PAGE>   69
Statement. Additions or changes to any information in your account registration
(for example, a change in registration from a joint account to an individual
account) may be made by submitting a written request to the Transfer Agent
accompanied by a signature guarantee by a financial institution that is a
participant in the Stock Transfer Agency Medallion Program ("STAMP") or such
other means or evidence of authority as may be acceptable to the Transfer Agent.
Additional requirements may be imposed. In the interests of economy and
convenience, certificates representing shares of the Funds are not issued.
Northern Funds may reproduce this Prospectus in an electronic format which may
be available on the Internet. If you have received this Prospectus in its
electronic format you, or your representative, may contact the Transfer Agent
for a free paper copy of this Prospectus by writing to Northern Funds Center at
P.O. Box 75986, Chicago, Illinois 60690-6319 or by calling 1-800-595-9111.


REDEEMING AND EXCHANGING SHARES

You can arrange to withdraw your investment in the Funds by selling some or all
of your shares. This process is known as "redeeming" your shares. The procedures
for redeeming shares differ depending on whether you purchase your shares
directly from Northern Funds or through Northern Trust or another Service
Organization. If you purchase your shares through an account at Northern Trust
or another Service Organization, you will redeem them in accordance with the
instructions pertaining to that account.

REDEEMING AND EXCHANGING DIRECTLY FROM THE FUNDS

When you purchase your shares directly from Northern Funds, you may redeem or
exchange shares by the methods described below. You may also use any of these
methods if you purchase your shares through an account at Northern Trust or
another Service Organization and you appear on Northern Funds' records as the
registered holder. You may call 1-800-595-9111 if you have any questions
regarding redemptions or exchanges.

         Northern Funds imposes no charges when you redeem or exchange shares.
Remember, however, when shares are purchased through Northern Trust or another
Service Organization, a fee may be charged by those institutions for providing
services in connection with your investment.

BY MAIL. You may redeem shares in any number or dollar amount by sending a
written request to Northern Funds, P.O. Box 75986, Chicago, Illinois 60690-6319.
The redemption request must state the number of shares or the dollar amount to
be redeemed and identify the Fund account number. If the redemption proceeds are

                                      -59-
<PAGE>   70
to be sent elsewhere than the address of record, each request must be
accompanied by a signature guarantee by a financial institution that
participates in STAMP or such other means or evidence of authority as may be
acceptable to the Transfer Agent. In addition, written requests for redemptions
exceeding $50,000 must be accompanied by a signature guarantee by a financial
institution that participates in STAMP or such other means or evidence of
authority as may be acceptable to the Transfer Agent. Additional requirements
may be imposed. A signature notarized by a notary public is unacceptable.
Northern Funds reserves the right to require signature guarantees in other
circumstances based on the amount of the redemption request or other factors,
and may impose additional requirements.

BY WIRE. If you authorize wire redemptions on your Purchase Application, shares
can be redeemed and the proceeds sent by federal wire transfer to a previously
designated account. You will be charged $15 for each wire redemption unless the
designated account is maintained at Northern Trust or an affiliated bank. The
minimum amount that may be redeemed by this method is $250. Northern Funds
reserves the right to change this minimum or to terminate the wire redemption
privilege at any time without notice. To change bank instructions, a written
request accompanied by a signature guarantee by a financial institution that
participates in STAMP, or such other means or evidence of authority acceptable
to the Transfer Agent, must be sent to Northern Funds, P.O. Box 75986, Chicago,
Illinois 60690-6319. Additional requirements may be imposed.

BY CHECK. You may also redeem shares of the Money Market Funds by redemption
check in amounts of $250 or more once the checkwriting privilege has been
established. When the check is presented to the Transfer Agent for payment, the
Transfer Agent, as your agent, will cause the particular Fund involved to redeem
a sufficient number of your shares to cover the amount of the check. Dividends
are earned until the check clears the Transfer Agent. You can establish the
checkwriting privilege by checking the appropriate box on the Purchase
Application, or if your Fund account is already opened, by completing the
appropriate form which may be obtained by calling the Transfer Agent at
1-800-595-9111. When establishing checkwriting for an account that is already
opened, the form must be signed by each person whose name appears on the account
accompanied by signature guarantees by a financial institution that participates
in STAMP or such other means or evidence of authority as may be acceptable to
the Transfer Agent. Additional requirements may be imposed.

         You may place stop payment requests on checks by calling the Transfer
Agent at 1-800-595-9111. A $20 fee will be charged for each stop payment
request. If there are insufficient shares in your account to cover the amount of
your redemption by check, the check will be returned, marked "insufficient
funds," and a fee of

                                      -60-
<PAGE>   71
$20 will be charged to the account. You may not use checks to close an account
or redeem shares purchased within the past fifteen days. Checks you write will
not be returned to you, although copies are available upon request. Northern
Funds reserves the right, at any time without prior notice, to suspend, limit or
terminate the checkwriting privilege or its use in any manner by any person.

SYSTEMATIC WITHDRAWALS. Northern Funds offers a Systematic Withdrawal Plan. If
you own shares of a Fund with a minimum value of $10,000, you may elect to have
a fixed sum redeemed at regular intervals ($250 minimum amount per withdrawal)
and distributed in cash or reinvested in one or more of the other Funds offered
by Northern Funds. See "Purchasing Shares Directly from the Funds -- Directed
Reinvestments." An application form and additional information may be obtained
from the Transfer Agent by calling 1-800-595-9111.

EXCHANGE PRIVILEGE. Northern Funds offers an exchange privilege that permits you
to exchange shares of one Fund for shares of another Fund offered by Northern
Funds. To establish the exchange privilege, you must check the appropriate box
on the Purchase Application or, if your Fund account is already opened, you may
send a written request to the Transfer Agent, and must establish or maintain
accounts with an identical title in each Fund involved in an exchange
transaction. In addition, the shares being exchanged must have a value of at
least $1,000 ($2,500 if a new account is being established by the exchange).

         Since an excessive number of exchanges may be disadvantageous to
Northern Funds, Northern Funds reserves the right, at any time without prior
notice, to suspend, limit or terminate the exchange privilege of any shareholder
who makes more than eight exchanges of shares in a year and/or two exchanges of
shares in a calendar quarter. A shareholder may continue making exchanges until
notified that the exchange privilege has been suspended, limited or terminated.
Questions regarding the exchange privilege may be directed to 1-800-595-9111 or
to your account officer at your Service Organization. Exchanges will be
processed only when the shares being acquired can be legally sold in the state
of the investor's residence.

         Exchanges may have tax consequences. No exchange fee is currently
imposed by Northern Funds on exchanges. Northern Funds reserves, however, the
right to impose a charge in the future.

TELEPHONE PRIVILEGE. This privilege permits you to redeem or exchange shares by
telephone. To establish the telephone privilege, you must check the appropriate
box on the Purchase Application, or if your Fund account is already opened, you
may send a written request to the Transfer Agent. The request must be signed by
each owner of the account and accompanied by

                                      -61-
<PAGE>   72
signature guarantees as provided below or such other means or evidence of
authority as may be acceptable to the Transfer Agent. Once you have established
the telephone privilege, you may use the telephone privilege by calling the
Transfer Agent at 1-800-595-9111.

         The Transfer Agent has adopted procedures in an effort to establish
reasonable safeguards against fraudulent telephone transactions. The proceeds
for redemption orders will be sent by check, by wire transfer or by transfer to
an account maintained at Northern Trust or an affiliated bank. All checks will
be made payable to the shareholder of record and mailed only to the
shareholder's address of record. The address of record for redemption checks may
be changed only by a written request accompanied by signature guarantees by a
financial institution that participates in STAMP or such other means or evidence
of authority as may be acceptable to the Transfer Agent and sent to Northern
Funds, P.O. Box 75986, Chicago, Illinois 60690-6319. Additionally, the Transfer
Agent utilizes recorded lines for telephone transactions and will request a form
of personal identification if such identification has been furnished to the
Transfer Agent. Neither Northern Funds 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 Northern Funds fails to
use reasonable procedures to verify the genuineness of telephone instructions,
it or its service providers may be liable for instructions that prove to be
fraudulent or unauthorized. In all other cases, you will bear the risk of loss.

         Northern Funds reserves the right to refuse a telephone redemption if
it believes it is advisable to do so. Procedures for redeeming shares by
telephone may be modified or terminated by Northern Funds at any time without
notice. During periods of substantial economic or market change, telephone
redemptions may be difficult to place. If you are unable to contact the Transfer
Agent by telephone, shares may also be redeemed by mail as described above under
the discussion of redemptions by mail.

REDEEMING AND EXCHANGING THROUGH NORTHERN TRUST AND OTHER INSTITUTIONS

If you purchase your shares through an account at Northern Trust or another
Service Organization, you will redeem or exchange them in accordance with the
instructions pertaining to that account. If you are listed on the books of
Northern Funds as the shareholder of record, you may also redeem and exchange
your shares using any of the methods described above under "Redeeming and
Exchanging Directly from the Funds." Questions regarding these redemptions or
exchanges should be directed to your account representative at Northern Trust or
another Service Organization. Although Northern Funds imposes no charges when
you redeem, when

                                      -62-
<PAGE>   73
shares are purchased through Northern Trust or another Service Organization a
fee may be charged by those institutions for providing services in connection
with your account.

ADDITIONAL REDEMPTION AND EXCHANGE INFORMATION

EFFECTIVE TIME AND PRICE OF REDEMPTIONS AND EXCHANGES. Redemption orders for
shares of a non-Money Market Fund are processed at the net asset value next
determined at 3:00 p.m. (Chicago Time) after receipt in good order by the
Transfer Agent by 3:00 p.m. (Chicago Time) on a Business Day. Redemption orders
for shares of a Money Market Fund are processed at the net asset value next
determined at 1:00 p.m. (Chicago Time) after receipt in good order by the
Transfer Agent by 1:00 p.m. (Chicago Time) on a Business Day. Good order means
that the request must include the following information: the account number and
Fund name; the amount of the transaction (as specified in dollars or number of
shares); the signatures of all account owners exactly as they are registered on
the account (except for telephone and wire redemptions); required signature
guarantees (if applicable); and other supporting legal documents that might be
required in the case of estates, corporations, trusts and certain other
accounts. Call 1-800-595-9111 for the additional documentation that may be
required of these entities. Exchange orders are likewise processed at the net
asset value per share next determined after receipt in good order by the
Transfer Agent on a Business Day.

PAYMENT OF REDEMPTION PROCEEDS -- NON-MONEY MARKET FUNDS. The non-Money Market
Funds will make payment for redeemed shares typically within one or two Business
Days, but no later than the seventh day after receipt by the Transfer Agent of a
request in good order on a Business Day, except as otherwise provided by the
rules of the SEC. However, if any portion of the shares to be redeemed
represents an investment made by check, the Funds may delay the payment of the
redemption proceeds until the Transfer Agent is reasonably satisfied that the
check has been collected, which could take up to fifteen days from the purchase
date. This procedure does not apply to shares purchased by money order or wire
payment.

PAYMENT OF REDEMPTION PROCEEDS -- MONEY MARKET FUNDS. If received by the
Transfer Agent by 1:00 p.m. (Chicago Time) on a Business Day, a redemption
request normally will result in proceeds being sent on the next Business Day,
unless payment in immediately available funds on the same Business Day is
specifically requested. Proceeds for redemption orders received on a
non-Business Day will normally be sent on the second Business Day after receipt
in good order. However, if any portion of the shares to be redeemed represents
an investment made by check, Northern Funds may delay the payment of the
redemption proceeds until the Transfer Agent is reasonably

                                      -63-
<PAGE>   74
satisfied that the check has been collected, which could take up to fifteen days
from the purchase date. Northern Funds 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 Fund.

MISCELLANEOUS REDEMPTION INFORMATION. All redemption proceeds will be sent by
check unless Northern Trust or the Transfer Agent is directed otherwise. The ACH
system may be utilized for payment of redemption proceeds. Redemptions may not
be processed if a shareholder has failed to submit a completed and signed
Purchase Application. Northern Funds may require any information reasonably
necessary to ensure that a redemption has been duly authorized.

         To relieve Northern Funds of the cost of maintaining uneconomical
accounts, Northern Funds reserves the right to redeem the shares held in any
account if at the time of any redemption of shares in the account, the net asset
value of the remaining shares in the account falls below $1,000. Before such
involuntary redemption would occur, you would be given at least 60 days' written
notice and, during that period, you could make an additional investment to
restore the account to at least the minimum amount, in which case there would be
no such redemption. Involuntary redemptions will not be made because the value
of shares in an account falls below the minimum amount solely because of a
decline in a Fund's net asset value. Any involuntary redemption would be at net
asset value. Northern Funds also reserves the right to redeem shares
involuntarily if it is otherwise appropriate to do so under the 1940 Act (see
"Amortized Cost Valuation" in the Additional Statement).


DISTRIBUTIONS AND TAXES

DISTRIBUTIONS

Each Money Market Fund's net investment income is declared as a dividend on each
Business Day on the shares that are outstanding at 1:00 p.m. (Chicago Time) on
the declaration date. Net investment income includes interest accrued on the
Fund's assets less the Fund's estimated expenses. Dividends from net investment
income are paid monthly. Net realized short-term capital gains, after reduction
for capital loss carry-forwards, if any, of a Fund may be distributed from time
to time during Northern Funds' fiscal year (but not less frequently than
annually). The Money Market Funds do not expect to realize net long-term capital
gains.

         Dividends from the net investment income of each of the U.S.
Government, Fixed Income, Intermediate Tax-Exempt, Tax-Exempt and

                                      -64-
<PAGE>   75
Florida Intermediate Tax-Exempt Funds are declared daily on each Business Day
and paid monthly. Dividends from the net investment income of the International
Fixed Income Fund are declared daily on each Business Day and paid quarterly.
Shares of these six Funds are entitled to the dividends declared by a Fund
beginning on the next Business Day after the purchase order is executed.

         Dividends from the net investment income of the other Funds are
declared and paid as follows:

         The net realized capital gains of each Fund are distributed at least
annually.

         Dividends and capital gain distributions, if any, will reduce the net
asset value of a Fund (other than a Money Market Fund) by the amount of the
dividend or capital gain distribution. Dividends and capital gain distributions,
if any, are automatically reinvested (without any sales charge or portfolio
transaction fee) in additional shares of the same Fund at their net asset value
determined on the payment date. You may, however, notify the Transfer Agent in
writing that you elect to have dividends and/or capital gain distributions paid
in cash or reinvested in shares of another Fund offered by Northern Funds at
their net asset value determined on the payment date (provided you maintain an
account in such Fund). This election will become effective for distributions
paid two days after its receipt by the Transfer Agent.

         Net loss, if any, from certain foreign currency transactions or
instruments that is otherwise taken into account with respect to the
International Fixed Income Fund 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 Fund's dividends may be treated as a return of capital,
nontaxable to the extent of a shareholder's tax basis in his or her shares.

TAXES

As with any investment, you should consider the tax implications of an
investment in Northern Funds. The following is only a short summary of the
important tax considerations generally affecting the Funds and their
shareholders. You should consult your tax adviser with specific reference to
your own tax situation. Northern Funds will send written notices to shareholders
annually regarding the tax status of distributions made by the Funds. The Funds
will determine annually the percentages of their respective net investment
income which are exempt from tax, which constitute an item of tax preference for
purposes of the federal alternative minimum tax, and which are fully taxable,
and will apply these percentages uniformly to all dividends declared from net
investment income during that year. These percentages may differ significantly
from the actual percentages for any particular day.

FEDERAL TAXES. Each Fund intends to qualify as a "regulated investment company"
under the Internal Revenue Code (the "Code"), meaning that to the extent a
Fund's earnings are distributed to shareholders as required by the Code, the
Fund itself is not required to pay federal income taxes.

         To qualify, a Fund will pay as dividends at least 90% of its investment
company taxable income and at least 90% of its net tax-exempt income (if any)
each year. Investment company taxable income includes, but is not limited to,
taxable interest, dividends and short-term capital gains less expenses.
Dividends based on either investment company taxable income (which includes
income resulting from investments in options and futures contracts) or the
excess of net short-term capital gain over net long-term capital loss are
treated as ordinary income in determining gross income for tax purposes, whether
or not the dividends are received in cash or additional shares. (Federal income
taxes for distributions to an IRA or other qualified retirement account are
deferred under the Code.)

         Dividends paid by the Tax-Exempt Funds (but not the other Funds) that
are derived from interest on Municipal Instruments ("exempt-interest dividends")
may be excludable from your federal taxable income (unless because of your
particular situation exclusion would be disallowed). You should note that income
that is not subject to federal income taxes may nevertheless have to be
considered along with other adjusted gross income in determining whether any
Social Security payments received by you are subject to federal income taxes.
You should also note that a portion of the exempt-interest dividends paid by the
Intermediate Tax-Exempt Fund, Tax-Exempt Fund, Florida Intermediate Tax-Exempt
Fund may be, and a portion of such dividends by the Municipal Money Market and
California Municipal Money Market Funds generally will be, an item of tax
preference for both corporate

                                      -66-
<PAGE>   77
and individual taxpayers in determining federal alternative minimum and
environmental tax liability. (Corporate taxpayers will be required to take into
account all exempt-interest dividends from the Tax-Exempt Funds in determining
certain adjustments for alternative minimum tax and environmental tax purposes.)
If you hold shares for six months or less, and during that time receive
exempt-interest dividends, any loss realized on the sale of those shares will be
disallowed to the extent of the exempt-interest dividends.

         Any distribution based on the excess of long-term capital gain over net
short-term capital loss will be taxable as a long-term capital gain, no matter
how long you hold Fund shares. If you hold shares for six months or less, and
during that time receive a distribution that is taxable as a long-term capital
gain, any loss realized on the sale of those shares will be treated as a
long-term loss to the extent of the earlier capital gain distribution.

         Before purchasing shares you should consider the effect of any capital
gain distributions and, for those Funds that do not declare dividends daily, any
net income dividends that are expected to be declared or that have been declared
but not yet paid. The per share price will be reduced by the amount of the
payment, so that a shareholder will, in effect, have paid full price for the
shares and then received a portion of the price back as a taxable distribution.
This is because at any given time the value of your shares includes the
undistributed net gains, if any, realized by a Fund on the sale of portfolio
securities, and undistributed dividends and interest received, less the Fund's
expenses. Because such gains and dividends are included in the price of your
shares, when they are distributed, the price of your shares is reduced by the
amount of the distribution. Accordingly, if your distribution is reinvested in
additional shares, the distribution has no effect on the value of your
investment; while you own more shares, the price of each share has been reduced
by the amount of the distribution. Likewise, if you take your distribution in
cash, the value of your shares after the record date will be reduced by the cash
received.

         Any dividends declared in October, November or December and payable to
shareholders of record during those months will be deemed to have been paid by a
Fund and received by shareholders on December 31, so long as the dividends are
actually paid, as expected, in January of the following year.

         Shareholders may realize a taxable gain or loss when redeeming,
transferring or exchanging their shares (or in using the Systematic Withdrawal
Plan to direct reinvestments), depending on the difference in the prices at
which the shares

                                      -67-
<PAGE>   78
were originally purchased and when redeemed, transferred or exchanged.

         Dividends and certain interest income earned by a Fund from foreign
securities may be subject to foreign withholding taxes or other taxes. So long
as more than 50% of the value of a Fund's total assets at the close of any
taxable year consists of stock or securities of foreign corporations, the Fund
may elect, for U.S. federal income tax purposes, to treat certain foreign taxes
paid by it, including generally any withholding taxes and other foreign income
taxes, as paid by its shareholders. It is possible that one or more of the
International Funds will make this election in certain years. Should a Fund make
the election, the amount of such foreign taxes paid by the Fund will be included
in its shareholders' income pro rata (in addition to taxable distributions
actually received by them), and each shareholder will be entitled either (a) to
credit his proportionate amounts of such taxes against applicable U.S. federal
income tax liabilities, or (b) if the shareholder itemizes deductions, to deduct
such proportionate amounts from applicable U.S. federal taxable income.

         If a Fund invests in certain "passive foreign investment companies"
("PFICs"), it would 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 it distributes the income to its
shareholders. If a Fund elects to treat the PFIC as a "qualified electing fund"
("QEF") and the PFIC furnishes certain financial information in the required
form, the Fund instead would be required to include in income each year its
allocable share of the ordinary earnings and net capital gains of the QEF,
whether or not received, and such amounts would be subject to the various
distribution requirements described above. In addition, a Fund could, as an
alternative, treat unrealized gains as though they were realized for tax
purposes.

         Northern Funds will be required in certain cases to withhold and remit
to the U.S. Treasury 31% of the dividends and distributions payable to any
investor (i) who has provided either an incorrect Social Security Number or
Taxpayer Identification Number or no number at all, (ii) who is subject to
withholding by the Internal Revenue Service for failure to properly include on
his return payments of interest or dividends, or (iii) who has failed to certify
to Northern Funds, when required to do so, that he is not subject to backup
withholding or is an "exempt recipient."

STATE AND LOCAL TAXES GENERALLY. Because your state and local taxes may be
different than the federal taxes described above, you should see your tax
adviser. In particular, dividends may be taxable under state or local law as
dividend income even though

                                      -68-
<PAGE>   79
all or part of those dividends come from interest on obligations that, if held
by you directly, would be free of such income taxes. Additionally, although the
U.S. Government Select Money Market Fund intends to invest principally in U.S.
Government securities the interest on which is generally exempt from state
income taxation, you should see your tax adviser to determine whether
distributions from the Fund are exempt in light of your particular
circumstances.

STATE AND LOCAL TAXES -- CALIFORNIA MUNICIPAL MONEY MARKET FUND. If, at the
close of each quarter of the California Municipal Money Market Fund's taxable
year, at least 50% of the value of its total assets consists of California
Municipal Instruments and certain specified federal obligations, and if the Fund
qualifies as a regulated investment company for federal tax purposes, then the
Fund will be qualified to pay dividends exempt from California state personal
income tax to its shareholders. If the Fund so qualifies, dividends derived from
interest attributable to California Municipal Instruments and such federal
obligations will be exempt from California state personal income tax. (Such
treatment may not apply, however, to investors who are "substantial users" or
"related persons" with respect to facilities financed by portfolio securities
held by the Fund.) Any dividends paid to shareholders subject to California
state franchise tax or California state corporate income tax may be taxed as
ordinary dividends to such shareholders notwithstanding that all or a portion of
such dividends are exempt from California state personal income tax.

         Except as noted with respect to the California state personal income
tax, dividends paid by the California Municipal Money Market Fund may be taxable
under state or local law as dividend income even though all or part of those
dividends come from interest on obligations that, if held by you directly, would
be free of such income taxes. Moreover, to the extent, if any, that dividends
paid by the Fund to its shareholders are derived from taxable interest or from
capital gains, such dividends will be subject to federal income tax and
California state personal income tax, if applicable, whether or not such
dividends are reinvested. Future legislative or administrative changes or court
decisions may materially affect the tax consequences of investing in the Fund.

STATE AND LOCAL TAXES -- FLORIDA INTERMEDIATE TAX-EXEMPT FUND. Florida does not
currently have an income tax for individuals, and therefore individual
shareholders of this Fund will not be subject to any Florida income tax on
amounts received from the Fund. However, Florida does impose an income tax on
certain corporations, so that such amounts may be taxable to corporate
shareholders.


                                      -69-
<PAGE>   80
         Florida also imposes an "intangibles tax" at the annual rate of 2 mills
or 0.20% on certain securities and other intangible assets owned by Florida
residents. With respect to the first mill, or first .10%, of the intangibles
tax, every natural person is entitled each year to an exemption of the first
$20,000 of the value of the property subject to the tax. A husband and wife
filing jointly will have an exemption of $40,000. With respect to the last one
mill, or last .10% of the intangibles tax, every natural person is entitled each
year to an exemption of the first $100,000 of the value of the property subject
to the tax. A husband and wife filing jointly will have an exemption of
$200,000.

         Obligations issued by the State of Florida or its municipalities,
counties, and other taxing districts, or by the U.S. Government, certain U.S.
Government agencies and certain U.S. territories and possessions (such as Guam,
Puerto Rico and the Virgin Islands), as well as cash, are exempt from this
intangibles tax. If on December 31 of any year the portfolio of the Florida
Intermediate Tax-Exempt Fund consists solely of such exempt assets, then the
Fund's shares will be entirely exempt from the Florida intangibles tax payable
in the following year.

         The Fund intends, but cannot guarantee, that its shares will qualify
for exemption from the Florida intangibles tax.

TAX TABLE

You may find it particularly useful to compare the tax-free yields of the
Tax-Exempt Funds to the equivalent yields from taxable investments. For an
investor in a low tax bracket, it may not be helpful to invest in a tax-exempt
investment if a higher after-tax yield can be achieved from a taxable
instrument.

         The following table illustrates the difference between hypothetical
tax-free yields and tax-equivalent yields for different tax brackets. You should
be aware, however, that tax brackets can change over time and that your tax
adviser should be consulted for specific yield calculations.

The tax-exempt yields used here are hypothetical and no assurance can be made
that the Funds will attain any particular yield. A Fund's yield fluctuates as
market conditions change. The tax brackets and related yield calculations are
based on the 1996 federal marginal tax rates indicated in the table. The table
does not reflect the phase out of personal exemptions and itemized deductions
which will apply to certain higher income taxpayers. In addition, the brackets
do not take into consideration the California state personal income tax or the
Florida intangible tax.

MANAGEMENT

BOARD OF TRUSTEES

The business and affairs of Northern Funds are managed under the direction of
its Board of Trustees. The Additional Statement contains the name of each
Trustee and other background information.

INVESTMENT ADVISER, TRANSFER AGENT AND CUSTODIAN

Northern Trust, with offices at 50 S. LaSalle Street, Chicago, Illinois 60675,
serves as Northern Funds' investment adviser, transfer agent and custodian. As
transfer agent, Northern Trust provides various administrative servicing
functions, and any shareholder inquiries may be directed to it.

         Northern Trust, 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 Trust was formed in 1889 with
capitalization of $1 million. As of June 30, 1996, Northern Trust Corporation
had approximately $21.8 billion in assets, $13.3 billion in deposits and
employed approximately 6,700 persons.

         Northern Trust and its affiliates administered in various capacities
(including as master trustee, investment manager or custodian) over $692.9
billion in assets as of June 30, 1996, including over $120 billion for which
Northern Trust and its affiliates had investment management responsibility.

         Subject to the general supervision of Northern Funds' Board of
Trustees, Northern Trust is responsible for making investment decisions for the
Funds and placing purchase and sale orders for portfolio securities. Northern
Trust 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 Northern Funds). In making investment
recommendations for the Funds, investment advisory personnel must not inquire or
take into consideration whether issuers of securities proposed for purchase or
sale for the Funds' accounts are customers of Northern Trust's commercial
banking department. These requirements are designed to prevent investment
advisory personnel for the Funds from knowing which companies have commercial
business with Northern Trust and from purchasing securities where they know the
proceeds will be used to repay loans to the bank.

         As compensation for its advisory services and its assumption of related
expenses, Northern Trust is entitled to a fee, computed daily and payable
monthly, at an annual rate of 0.60% of the average daily net assets of each of
the Money Market Funds; 0.75% of the average daily net assets of each of the
U.S. Government, Fixed Income, Intermediate Tax-Exempt, Tax-Exempt and Florida
Intermediate Tax-Exempt Funds; 0.90% of the average daily net assets of the
International Fixed Income Fund; 1.00% of the average daily net assets of each
of the Income Equity and Growth Equity Funds; 1.20% of the average daily net
assets of each of the Select Equity, Small Cap, International Growth Equity,
International Select Equity and Technology Funds; and 0.60% of the average daily
net assets of the Stock Index Fund. Although these advisory fee rates (except
for the Money Market Funds and Stock Index Fund) are higher than the rates
payable by most mutual funds, the Board of Trustees believes they are comparable
to the rates payable by other fixed income, equity and international funds.

         During Nothern Funds' fiscal year ended March 31, 1996, Northern Trust
received investment management fees (after waivers) at the annualized rates of
0.37%, 0.36%, 0.37%, 0.22% and 0.27% of the average daily net assets of the
Money Market Fund, U.S. Government Money Market Fund, Municipal Money Market
Fund, U.S. Government Select Money Market Fund and California Municipal Money
Market Fund, respectively, and at the annualized rates set forth above under
"Expense Summary" with respect to the other Funds.

         Northern Trust also receives compensation as Northern Funds' custodian
and transfer agent. The fees payable by the Funds for these services are
described in the Additional Statement.

         Northern Trust may at its own expense, provide compensation to certain
dealers and other institutions whose customers purchase shares of a Fund. The
amount of such compensation may be made on a one-time and/or periodic basis, and
may equal or exceed the annual fees that are earned by Northern from a Fund and
are attributable to shares held by such customers. Such compensation will not
represent an additional expense to the Funds or their shareholders, since it
will be paid from the assets of Northern Trust or its affiliates.

         The Money Market, Fixed Income and Equity Funds are advised by Northern
Trust's Investment Services Group. James M. Snyder, Vice President of Northern
Trust since 1980, Senior Vice President since 1991 and Chief Investment Officer
since 1995, oversees the management of all fixed income, equity and money market
assets managed by Northern Trust and is the head of Northern's Investment
Services Group. Mr. Snyder received his B.S. degree from Indiana University and
his M.B.A. degree from DePaul University. He is a Chartered Financial Analyst
and a member of the Investment Analysts Society of Chicago.

ADMINISTRATOR AND DISTRIBUTOR

Sunstone Financial Group, Inc. ("Sunstone"), 207 E. Buffalo Street, Suite 400,
Milwaukee, Wisconsin 53202, acts as administrator and distributor for Northern
Funds. Shares of the Funds are sold by Sunstone, as distributor, on a continuous
basis. As compensation for its administrative services (which include clerical,
compliance, regulatory and other services) and the assumption of related
expenses, Sunstone is entitled to a fee, computed daily and payable monthly, at
an annual rate of 0.15% of Northern Funds' average net assets. No compensation
is payable by Northern Funds to Sunstone for its distribution services.

SERVICE ORGANIZATIONS

Northern Funds may enter into agreements with Service Organizations such as
banks, corporations, brokers, dealers and other financial institutions,
including Northern Trust, concerning the provision of support and/or
distribution services to their customers who own Fund shares. These services,
which are described more fully in the Additional Statement, may include support
services such as assisting investors in processing administrative purchase,
exchange and redemption requests; processing dividend and distribution payments
from the Funds; providing information to customers showing their positions in
the Funds; and providing subaccounting with respect to Fund shares beneficially
owned by customers or the information necessary for subaccounting. In addition,
Service Organizations may provide assistance, such as the forwarding of sales
literature and advertising to their customers, in connection with the
distribution of Fund shares. For their services, Service Organizations may
receive fees from a Fund at annual rates of up to 0.25% of the

                                      -75-
<PAGE>   86
average daily net asset value of the shares covered by their agreements.

         Service Organizations may charge their customers fees for providing
administrative services in connection with investments in a Fund. Investors
should contact their Service Organization with respect to these fees and the
particular Service Organization's procedures for purchasing and redeeming
shares. It is the responsibility of Service Organizations to transmit purchase
and redemption orders and record those orders on a timely basis in accordance
with their agreements with their customers.

         Conflict-of-interest restrictions may apply to the receipt of
compensation paid by Northern Funds in connection with the investment of
fiduciary funds in Fund shares. Institutions, including banks regulated by the
Comptroller of the Currency, Federal Reserve Board 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 their legal counsel before entering into
agreements with Northern Funds.

         The Glass-Steagall Act and other applicable laws, among other things,
prohibit banks from engaging in the business of underwriting securities.
Accordingly, banks will be engaged under agreements with Northern Funds only to
perform the administrative and investor servicing functions described above, and
will represent that the services provided by them under the agreements will not
be primarily intended to result in the sale of Fund shares.

         Agreements that contemplate the provision of distribution services by
Service Organizations are governed by a Distribution and Service Plan (the
"Plan") that has been adopted by Northern Funds pursuant to Rule 12b-1 under the
1940 Act. No payments are made to Sunstone under the Plan. However, payments to
Service Organizations, including Northern Trust, under the Plan are not tied
directly to their own out-of-pocket expenses and therefore may be used as they
elect (for example, to defray their overhead expenses), and may exceed their
direct and indirect costs.

EXPENSES

Except as set forth above and in the Additional Statement, each Fund is
responsible for the payment of its expenses. These expenses include, without
limitation, the fees and expenses payable to Northern Trust and Sunstone,
brokerage fees and commissions, fees for the registration or qualification of
Fund shares under federal or state securities laws, expenses of the organization
of Northern Funds, 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
Northern Funds for violation of any law, legal, tax and auditing fees and
expenses, expenses of preparing and printing

                                      -76-
<PAGE>   87
prospectuses, statements of additional information, proxy materials, reports and
notices and the printing and distributing of the same to the Funds' shareholders
and regulatory authorities, compensation and expenses of its Trustees, payments
to Service Organizations, fees of industry organizations such as the Investment
Company Institute, and miscellaneous and extraordinary expenses incurred by
Northern Funds.

         Northern Trust and Sunstone intend to voluntarily reimburse a portion
of the Funds' expenses and/or reduce their advisory and administrative fees from
the Funds during the current fiscal year. The result of these reimbursements and
fee reductions will be to increase the performance of the Funds during the
periods for which the reductions and reimbursements are made.

FURTHER INFORMATION

DETERMINING SHARE PRICE

Net asset value per share for purposes of purchases and redemptions is
calculated by Northern Trust on each Business Day as of 3:00 p.m. (Chicago Time)
for each non-Money Market Fund, and as of 1:00 p.m. (Chicago Time) for each
Money Market Fund. Net asset value is calculated by dividing the value of all
securities and other assets belonging to a Fund, less the liabilities charged to
a Fund, by the number of the Fund's outstanding shares.

         In seeking to maintain a net asset value of $1.00 per share with
respect to each Money Market Fund for purposes of purchases and redemptions,
Northern Funds values the portfolio securities held by each of the Money Market
Funds pursuant to the amortized cost method of valuation described in the
Additional Statement under "Amortized Cost Valuation."

         Securities held by the other Funds that are listed on a recognized U.S.
or foreign securities exchange are valued at the last quoted sales price on the
securities exchange on which the 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 securities listed on a U.S. exchange are
not traded on a valuation date, they will be valued at the last quoted bid
price. If securities traded on a foreign securities exchange are not traded on a
valuation date, they will be valued at the most recent quoted sales price.
Securities that are traded in the U.S. over-the-counter markets, absent a last
quoted sales price, 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. Any securities for which no
current quotations are readily available are valued at fair value as determined
in good faith by Northern Trust under the supervision of the Board of Trustees.
Temporary short-term investments are valued at amortized cost which Northern
Trust has determined,

                                      -77-
<PAGE>   88
pursuant to Board authorization, approximates market value. Securities may be
valued on the basis of prices provided by independent pricing services when
those prices are believed to reflect the fair market value of the securities.

ADVERTISING PERFORMANCE

The performance of each Fund may be compared to those of other mutual funds with
similar investment objectives and to stock, bond 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 Fund may be compared to data prepared by Lipper Analytical
Services, Inc. or to the S&P 500 Index, the Russell 2000 or 1000 Small Stock
Index, the Consumer Price Index or the Dow Jones Industrial Average. In
addition, performance of the International Funds may be compared to the Morgan
Stanley Capital International Europe, Australia and Far East Index ("EAFE"), the
Morgan Stanley EAFE and Emerging Markets Free Index and the J.P. Morgan
International Government Bond Index, and performance of the Fixed Income and
U.S. Government Funds may be compared to the Lehman Brothers Government Bond
Index (or its two components, the Treasury Bond Index and Agency Bond Index),
the Lehman Brothers Corporate Bond Index and the Lehman Brothers Intermediate
Government Bond Index. Performance of the Intermediate Tax-Exempt and Tax-Exempt
Funds may be compared to the Lehman Brothers Municipal Bond or 5-Year Municipal
Bond Indices, performance of the Florida Intermediate Tax-Exempt Fund may be
compared to the Lehman Brothers Mutual Fund Florida Intermediate Municipal Bond
Index and performance of the Income Equity Fund may be compared to the Merrill
Lynch Investment Grade Convertible Bond Index. Performance of the Technology
Fund may be compared to the Hambrecht and Quist Technology Index, the SoundView
Technology Index, the technology grouping of the S&P 500 Index and any other
comparable technology index. Performance data as reported in national financial
publications such as Money Magazine, 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 Fund. From time to time, the
Funds may also quote the mutual fund ratings of Morningstar, Inc. and other
services in their advertising materials.

         A Fund (other than the Money Market Funds) calculates its total return
on an "average annual total return" basis for various periods from the date the
Fund commences investment operations and for other periods as permitted under
SEC rules. Average annual total return reflects the average annual percentage
change in value of an investment over the measuring period. Total return 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 a Fund's shares and assume that any dividends and capital gain
distributions are reinvested. When

                                      -78-
<PAGE>   89
considering average total return figures for periods longer than one year, you
should note that the annual total return for any one year may be more or less
than the average for the entire period. A Fund may also advertise its total
return on an aggregate, year-by-year or other basis for various specified
periods through charts, graphs, schedules or quotations.

         The yield of a Fund (other than the Money Market Funds) is computed
based on the Fund's net income during a specified 30-day (or one-month) period.
More specifically, the Fund's yield is computed by dividing its per share net
income during the relevant period by the per share net asset value on the last
day of the period and annualizing the result on a semi-annual basis. The yield
of a Money Market Fund is computed based on the Fund's net income during a
specified seven-day period. The net investment income is then "annualized." That
is, the amount of net investment income generated by the investment during the
period is assumed to be generated each week over a 52-week period and is shown
as a percentage of the investment. The "effective" yield of a Money Market Fund
is calculated similarly but, when annualized, the net investment income
generated by the investment 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 for a Tax-Exempt Fund shows the amount of
taxable yield needed to produce an after-tax equivalent of a tax-free yield, and
is calculated by increasing the yield (as calculated above) by the amount
necessary to reflect the payment of federal and/or state income taxes at a
stated rate. The tax-equivalent yield for a Tax-Exempt Fund will always be
higher than the Fund's yield.

         Performance is based on historical earnings and is not intended to
indicate future performance. The investment return and principal value of an
investment in a Fund will fluctuate so that shares, when redeemed, 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. Changes in the net asset value should be
considered in ascertaining the total return to shareholders for a given period.
Total return data should also be considered in light of the risks associated
with a Fund's composition, quality, operating expenses and market conditions.
Any fees charged by Northern Trust or a Service Organization directly to its
customers in connection with investments in the Funds will not be included in
Northern Funds' calculations of performance data.

VOTING RIGHTS

Northern Funds was formed as a Massachusetts Business Trust on October 12, 1993
under an Agreement and Declaration of Trust (the "Trust Agreement"). The Trust
Agreement permits the Board of Trustees to issue an unlimited number of shares
of beneficial

                                      -79-
<PAGE>   90
interest of one or more separate series representing interests in different
investment portfolios. Northern Funds currently offers nineteen separate Funds,
which are described in this Prospectus.

         Shareholders are entitled to one vote for each full share held and
proportionate fractional votes for fractional shares held. Each series entitled
to vote on a matter will vote in the aggregate and not by series, except as
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 where the law requires voting by series. Voting rights are not
cumulative and, accordingly, the holders of more than 50% of the aggregate
shares of Northern Funds may elect all of the Trustees.

         Northern Funds does not presently intend to hold annual meetings of
shareholders except as required by the 1940 Act or other applicable law.
Pursuant to the Trust Agreement, 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, Northern Funds will assist in shareholder communications
in connection with the meeting.

         As of July 15, 1996, Northern Trust possessed sole or shared voting or
investment power for its customer accounts with respect to more than 50% of the
outstanding shares of Northern Funds.

SHAREHOLDER REPORTS

Shareholders of record will be provided each year with a semi-annual report
showing portfolio investments and other information as of September 30 and,
after the close of the Funds' fiscal year March 31, with an annual report
containing audited financial statements. To eliminate unnecessary duplication,
only one copy of shareholder reports will be sent to shareholders with the same
mailing address. Shareholders who desire a duplicate copy of shareholder reports
to be mailed to their residence should call 1-800-595-9111.

RETIREMENT PLANS

Shares of the Funds may be purchased in connection with certain tax-sheltered
retirement plans, including profit-sharing plans, 401(k) plans, money purchase
pension plans, target benefit plans and individual retirement accounts. Further
information about how to participate in these plans, the fees charged and the
limits on contributions can be obtained from Northern Trust. To invest through
any of the tax-sheltered retirement plans, please call Northern Trust for
information and the required separate application. To determine whether the
benefits of a tax-sheltered retirement plan are available and/or appropriate, a
shareholder should consult with a tax adviser.

MISCELLANEOUS

The address of Northern Funds is 207 E. Buffalo Street, Suite 400, Milwaukee,
Wisconsin 53202 and the telephone number is 1-800-595-9111. Northern Funds is
registered as an open-end management investment company under the 1940 Act, and
each of the Funds (other than the California Municipal Money Market Fund, the
Florida Intermediate Tax-Exempt Fund and the International Fixed Income Fund) is
classified under that Act as a diversified portfolio.

         As used in this Prospectus, "Business Day" means each day Northern
Trust and the New York Stock Exchange (the "Exchange) are open, which is Monday
through Friday, except for holidays observed by Northern Trust and/or the
Exchange. In 1996, these holidays are New Year's Day, Martin Luther King, Jr.
Day, Presidents' Day, Good Friday (except for the Money Market Funds), Memorial
Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving and
Christmas. On days when Northern Trust or the Exchange closes early as a result
of unusual weather or other conditions, the right is reserved to advance the
time by which purchase and redemption requests must be received. In addition, on
any Business Day when the Public Securities Association ("PSA") recommends that
the securities markets close early, the Funds reserve the right to cease or to
advance the deadline for accepting purchase and redemption orders for same
Business Day credit up to one hour before the PSA recommended closing time.
Purchase and redemption requests received after the advanced closing time will
be effected on the next Business Day. Northern Trust is not required to
calculate the net asset value of a Fund on days during which no shares are
tendered to a Fund for redemption and no orders to purchase or sell shares are
received by a Fund, or on days on which there is an insufficient degree of
trading in the Fund's portfolio securities for changes in the value of such
securities to affect materially the net asset value per share.

         From time to time, Northern Funds' distributor may provide promotional
incentives to brokers whose representatives have sold or are expected to sell
shares of the Funds. At various times, the distributor may implement programs
under which a broker's sales force may be eligible to win cash or non-cash
awards for sales efforts, and may finance broker sales contests or recognition
programs conforming to criteria established by the distributor. The distributor
may also provide marketing services to brokers consisting of written
informational material relating to sales incentive campaigns conducted by such
brokers for their representatives.

         Northern Trust is sometimes referred to as "The Northern Trust Bank" in
advertisements and other literature.

                        ADDITIONAL INVESTMENT INFORMATION


INVESTMENT OBJECTIVES AND POLICIES

         The following supplements the investment objectives and policies of the
Funds as set forth in the Prospectus.

                  MONEY MARKET FUNDS

                           Money Market Fund seeks to maximize current income to
                           the extent consistent with the preservation of
                           capital and maintenance of liquidity by investing
                           only in high-quality money market instruments.

                           U.S. Government Money Market Fund has the same
                           objective as the Money Market Fund but invests
                           primarily in securities issued or guaranteed by the
                           U.S. government, its agencies or instrumentalities
                           and related repurchase agreements.

                           Municipal Money Market Fund seeks high current income
                           exempt from regular federal tax to the extent
                           consistent with preserving capital by investing
                           mainly in short-term Municipal Instruments.

                           U.S. Government Select Money Market Fund seeks 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.

                           California Municipal Money Market Fund seeks to
                           provide its shareholders to the extent consistent
                           with the preservation of capital and prescribed
                           portfolio standards, a high level of income exempt
                           from regular federal income tax and California state
                           personal income tax.

                  FIXED INCOME FUNDS

                           U.S. Government Fund seeks high current income from
                           U.S. government securities. The Fund's
                           dollar-weighted average maturity is anticipated to
                           range between one and ten years. It is designed for
                           investors who seek greater principal stability than
                           is generally available from higher yielding corporate
                           bonds.

                           Fixed Income Fund seeks high current income from a
                           broad range of bonds and other fixed income


                                       -4-
<PAGE>   97
                           securities. It is designed for investors who seek
                           income and greater stability of principal than is
                           generally available from longer-term, higher yielding
                           bonds. The Fund's average maturity is anticipated to
                           range between seven and twelve years. This Fund
                           generally presents greater risk and reward potential
                           than the U.S. Government Fund.

                           International Fixed Income Fund seeks to maximize
                           total return consistent with reasonable risk while
                           investing in foreign securities markets. Total return
                           is comprised of current income and value fluctuations
                           from investing in bonds and other fixed income
                           securities of foreign issuers.

                  TAX-EXEMPT FUNDS

                           Intermediate Tax-Exempt Fund seeks high current
                           income exempt from regular federal income tax. The
                           Fund invests in a broad range of Municipal
                           Instruments with an expected average maturity of
                           three to ten years.

                           Tax-Exempt Fund also seeks high current income exempt
                           from regular federal income tax by investing in
                           Municipal Instruments with an expected average
                           maturity of ten to thirty years.

                           Florida Intermediate Tax-Exempt Fund seeks a high
                           level of current income exempt from regular federal
                           income tax. The Fund intends, but cannot guarantee,
                           that its shares will qualify for exemption from the
                           Florida intangibles tax.

                  EQUITY FUNDS

                           Income Equity Fund seeks to achieve high current
                           income and, as a secondary objective, longer-term
                           capital appreciation. The Fund invests in convertible
                           and other equity securities. Because it emphasizes
                           high current income, this Fund is likely to have the
                           least price fluctuation of Northern Fund's equity
                           funds.

                           Growth Equity Fund seeks long-term capital
                           appreciation by investing mainly in the equity
                           securities of growth companies. It is designed for
                           investors willing to accept above-average price
                           volatility in search of long-term reward.

                           Select Equity Fund is also for the more aggressive
                           investor, seeking long-term capital appreciation by


                                       -5-
<PAGE>   98
                           investing principally in common stocks of companies
                           the adviser believes to have superior growth
                           characteristics. Any income is incidental to this
                           objective.

                           Small Cap Fund seeks long-term capital appreciation;
                           any income is incidental to this objective. Because
                           it invests principally in the equity securities of
                           smaller companies, this Fund is likely to have more
                           price volatility than the Growth Equity and Select
                           Equity Funds.

                           International Growth Equity Fund offers the potential
                           benefits of international diversification to
                           investors willing to accept above-average price
                           volatility while seeking long-term capital
                           appreciation. While subject to additional risks such
                           as currency fluctuations and the higher volatility of
                           foreign securities, this Fund uses diversification,
                           in an effort to control risk.

                           International Select Equity Fund seeks long-term
                           growth by investing principally in common stock of
                           foreign issuers that the adviser believes are growing
                           faster than their markets. Because fewer countries
                           and securities are generally represented in this Fund
                           than in the International Growth Equity Fund, it is
                           likely to experience more price volatility.

                           Technology Fund seeks long-term capital appreciation
                           by investing principally in equity securities and
                           securities convertible into common stock of companies
                           that develop, produce or distribute products and
                           services related to advances in technology. The Fund
                           will, under normal market conditions, invest at least
                           65% of the value of its total assets in securities of
                           companies principally engaged in technology business
                           activities. An issuer is considered principally
                           engaged in technology business activities if such
                           issuer is listed on the Hambrecht and Quist
                           Technology Index, the SoundView Technology Index, the
                           technology grouping of the S&P 500 Index or any other
                           comparable index.

                           The SoundView Technology Index includes
                           approximately 100 companies from the design,
                           automation, communications, mainframe computer,
                           microcomputer, minicomputer, peripherals,
                           semiconductor, software and related services
                           industries.  The Hambrecht & Quist Technology Index

<PAGE>   99
                           (the "H&Q Index") is comprised of publicly traded
                           stocks of approximately 200 technology companies. The
                           H&Q Index includes companies in the electronics,
                           medical and related technologies industries and is a
                           market capitalization weighted index. Changes in the
                           indices may occur when SoundView or H&Q choose to
                           modify their indices or as mergers, acquisitions and
                           failures dictate. Such changes may happen with fair
                           regularity owing to the fast-changing nature of the
                           technology industries.

                           Stock Index Fund seeks to provide investment results
                           approximating the aggregate price and dividend
                           performance of the securities included in the S&P 500
                           Index.

         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, although there is no market for such deposits. Bank notes and bankers'
acceptances rank junior to deposit liabilities of the bank 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.

         A Fund may invest a portion of its net 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


                                       -7-
<PAGE>   100
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.

         GUARANTEED INVESTMENT CONTRACTS. A guaranteed investment contract
("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. The Money Market Fund and Fixed Income Fund 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 Trust. 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 normally be
considered illiquid investments, and will be acquired subject to the limitation
on illiquid investments.

         REPURCHASE AGREEMENTS. Each Fund may 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"). Repurchase agreements are considered to be loans under the
Investment Company Act of 1940 (the "1940 Act"). 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 Fund's
acquisition of the securities and normally will be within a shorter period of
time. Securities subject to repurchase agreements are held either by Northern
Funds' 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 Fund to possible loss because of adverse market
action or delay in connection with the disposition of the underlying
obligations.

         REVERSE REPURCHASE AGREEMENTS. A Fund may borrow funds 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 are considered to be
borrowings under the 1940 Act. Reverse repurchase agreements involve the risk
that the market value of the securities sold by a


                                       -8-
<PAGE>   101
Fund may decline below the repurchase price. A Fund will pay interest on amounts
obtained pursuant to a reverse repurchase agreement. While reverse repurchase
agreements are outstanding, a Fund will maintain in a segregated account cash,
U.S. Government securities or other liquid high-grade debt securities of an
amount at least equal to the market value of the securities, plus accrued
interest, subject to the agreement.

         VARIABLE AND FLOATING RATE INSTRUMENTS. With respect to the variable
and floating rate instruments that may be acquired by the Funds as described in
the Prospectus, Northern Trust 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 to meet payment on demand. In determining weighted average portfolio
maturity, an instrument may, subject to applicable 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 a Fund can recover payment
of principal as specified in the instrument. Where necessary to ensure that a
variable or floating rate instrument is of the minimum required credit quality
for a Fund, 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.

         FORWARD COMMITMENTS, WHEN-ISSUED SECURITIES AND DELAYED-DELIVERY
TRANSACTIONS. Each Fund 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 Fund to purchase
or sell securities at a future date. The price of the underlying securities
(usually expressed in terms of yield) and the date when the securities will be
delivered and paid for (the settlement date) are fixed at the time the
transaction is negotiated. When-issued purchases and forward commitment
transactions are normally negotiated directly with the other party.

         A Fund will purchase securities on a when-issued basis or purchase or
sell securities on a forward commitment basis only with the intention of
completing the transaction and actually purchasing or selling the securities. If
deemed advisable as a matter of investment strategy, however, a Fund may dispose
of or negotiate a commitment after entering into it. A Fund also may sell
securities it has committed to purchase before those securities are delivered to
the Fund on the settlement date.

         When a Fund purchases securities on a when-issued, delayed-delivery or
forward commitment basis, the Fund's custodian (or subcustodian) will maintain
in a segregated account cash, U.S. Government securities or other liquid
securities having a value (determined daily) at least equal to the amount of the
Fund's purchase commitments. In the case of a forward commitment to sell


                                       -9-
<PAGE>   102
portfolio securities, the custodian or subcustodian will hold the portfolio
securities themselves in a segregated account while the commitment is
outstanding. These procedures are designed to ensure that the Fund 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 Fund's average dollar-weighted maturity, the maturity of
when-issued, delayed-delivery or forward commitment securities will be
calculated from the commitment date.

         UNITED STATES GOVERNMENT OBLIGATIONS. Examples of the types of U.S.
Government obligations that may be acquired by the Funds 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
("FNMA"), Government National Mortgage Association ("GNMA"), General Services
Administration, Student Loan Marketing Association ("SLMA"), Central Bank for
Cooperatives, Federal Home Loan Mortgage Corporation ("FHLMC"), Federal
Intermediate Credit Banks and Maritime Administration.

         SUPRANATIONAL BANK OBLIGATIONS. A Fund 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 among nations (e.g., the International Bank
for Reconstruction and Development). 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 OBLIGATIONS. Within the past several years, 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." The Funds may purchase securities
registered in the STRIPS program. Under the STRIPS program, the Funds are able
to have their 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 Funds, other than the U.S. Government Select Money
Market Fund, may acquire U.S. Government obligations and their unmatured
interest coupons that have been separated ("stripped") by their holder,
typically a custodian bank or


                                      -10-
<PAGE>   103
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. Northern Funds is unaware
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 Funds, including stripped mortgage-backed securities.

         ASSET-BACKED SECURITIES. To the extent described in the Prospectus, the
Funds 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 periodically,
thus in effect "passing through" such 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 Funds
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 GNMA include GNMA Mortgage Pass-Through Certificates (also known as "Ginnie
Maes"), which are guaranteed as to the timely payment of principal and


                                      -11-
<PAGE>   104
interest by GNMA and 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 FNMA include FNMA Guaranteed
Mortgage Pass-Through Certificates (also known as "Fannie Maes"), which are
solely the obligations of 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 stockholders. Fannie Maes are guaranteed as to timely
payment of the principal and interest by FNMA. Mortgage-related securities
issued by 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 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 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.

         MUNICIPAL INSTRUMENTS. Opinions relating to the validity of Municipal
Instruments (including California Municipal Instruments and Florida Municipal
Instruments) and to federal and state tax issues relating to these securities
are rendered by counsel to the respective issuing authorities at the time of
issuance. Such opinions may contain various assumptions, qualifications or
exceptions that are reasonably acceptable to Northern Trust. Neither Northern
Funds nor Northern Trust 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
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.


                                      -12-
<PAGE>   105
         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.
Northern Funds 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 or which proposals, if any, might be enacted. Such
proposals, if enacted, might materially and adversely affect the availability of
Municipal Instruments for investment by the Intermediate Tax-Exempt, Tax-Exempt,
Florida Intermediate Tax-Exempt, California Municipal Money Market and Municipal
Money Market Funds and the Funds' liquidity and value. In such an event the
Board of Trustees would reevaluate the Funds' investment objectives and policies
and consider changes in their structure or possible dissolution.

         Certain of the Municipal Instruments held by a Fund may be insured as
to the timely payment of principal and interest. The insurance policies will
usually be obtained by the issuer of the Municipal Instrument at the time of its
original issuance. In the event that the issuer defaults on an interest or
principal payment, the insurer will be notified and will be required to make
payment to the bondholders. There is, however, no guarantee that the insurer
will meet its obligations. In addition, such insurance will not protect against
market fluctuations caused by changes in interest rates and other factors. A
Fund may invest more than 25% of its total assets in Municipal Instruments
covered by insurance policies.

         Interest earned by the Intermediate Tax-Exempt Fund, Tax-Exempt Fund or
Florida Intermediate Tax-Exempt Fund 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 Fund meets its fundamental policy that at
least 80% of its annual gross income be derived from Municipal Instruments.

         As described in the Prospectus, the Tax-Exempt Funds may invest in
municipal leases, which may be considered liquid under guidelines established by
Northern Funds' Board of Trustees. The guidelines will provide for determination
of the liquidity and proper valuation of a municipal lease obligation based on
factors including the following: (1) the frequency of trades and quotes for the
obligation; (2) the number of dealers willing to purchase or sell the security
and the number of other potential buyers; (3) the willingness of dealers to
undertake to make a market in the security; and (4) the nature of the
marketplace trades, including


                                      -13-
<PAGE>   106
the time needed to dispose of the security, the method of soliciting offers and
the mechanics of transfer. Northern Trust, under the supervision of Northern
Funds' Board of Trustees, will also consider the continued marketability of a
municipal lease obligation based upon an analysis of the general credit quality
of the municipality issuing the obligation and the essentiality to the
municipality of the property covered by the lease.

         STANDBY COMMITMENTS. The California Municipal Money Market, Municipal
Money Market, Intermediate Tax-Exempt, Tax-Exempt and Florida Intermediate
Tax-Exempt Funds may enter into standby commitments with respect to Municipal
Instruments held by them. Under a standby commitment, a dealer agrees to
purchase at a Fund's option a specified Municipal Instrument. Standby
commitments may be exercisable by a Fund at any time before the maturity of the
underlying Municipal Instruments and may be sold, transferred or assigned only
with the instruments involved.

         The Funds expect that standby commitments will generally be available
without the payment of any direct or indirect consideration. However, if
necessary or advisable, the Funds 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 a Fund will not exceed 1/2 of
1% of the value of the Fund's total assets calculated immediately after each
standby commitment is acquired.

         The Funds intend to enter into standby commitments only with dealers,
banks and broker-dealers which, in Northern Trust's opinion, present minimal
credit risks. The Funds will acquire standby commitments solely to facilitate
portfolio liquidity and do not intend to exercise their rights thereunder for
trading purposes. The acquisition of a standby commitment will not affect the
valuation of the underlying Municipal Instrument. The actual standby commitment
will be valued at zero in determining net asset value. Accordingly, where a Fund
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
Fund and will be reflected in realized gain or loss when the commitment is
exercised or expires.

         WARRANTS. The Income Equity, Growth Equity, Select Equity, Small Cap,
International Growth Equity, International Select Equity and Technology Funds
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 Fund could lose the
purchase value of a warrant if the right to subscribe to additional shares is
not exercised prior to the warrant's


                                      -14-
<PAGE>   107
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 Fund will
not invest more than 5% of its total assets, taken at market value, in warrants,
or more than 2% of its total assets, taken at market value, in warrants not
listed on the New York or American Stock Exchanges or a major foreign exchange.
Warrants acquired by a Fund in shares or attached to other securities are not
subject to this restriction. The Money Market Funds and the U.S. Government,
Fixed Income, Intermediate Tax-Exempt, Tax-Exempt, Florida Intermediate
Tax-Exempt, International Fixed Income and Stock Index Funds do not intend to
invest in warrants.

         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 Fixed Income, International Fixed Income, Income
Equity, Growth Equity, Select Equity, Small Cap, International Growth Equity,
International Select Equity and Technology Funds are authorized to enter into
forward 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 may allow a Fund to establish a
rate of exchange for a future point in time.

         A Fund may enter into forward foreign currency exchange contracts in
several circumstances. For example, when entering into a contract for the
purchase or sale of a security, a Fund 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.

         In addition, when Northern Trust 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 Fund 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 Fund's securities denominated in such foreign currency.
Similarly, when the securities held by a Fund create a short position in a
foreign currency, a Fund 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


                                      -15-
<PAGE>   108
forward contract is entered into and the date it matures. 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
Fund will also incur costs in connection with forward foreign currency exchange
contracts and conversions of foreign currencies and U.S. dollars. In addition,
Northern Trust may purchase or sell forward foreign currency exchange contracts
for the International Fixed Income Fund, International Growth Equity Fund and
International Select Equity Fund (collectively, the "International Funds") to
seek to increase total return when Northern Trust anticipates that the foreign
currency will appreciate or depreciate in value, but securities denominated in
that currency do not in Northern Trust's view present attractive investment
opportunities and are not held by a Fund.

         A separate account consisting of liquid assets, such as cash, U.S.
Government securities or other liquid securities, equal to the amount of a
Fund's assets that could be required to consummate forward contracts will be
established with the Fund's custodian except to the extent the contracts are
otherwise "covered." For the purpose of determining the adequacy of the
securities in the account, the deposited securities will be valued at market or
fair value. If the market or fair value of such securities declines, additional
cash or securities will be placed in the account daily so that the value of the
account will equal the amount of such commitments by the Fund. A forward
contract to sell a foreign currency is "covered" if a Fund owns the currency (or
securities denominated in the currency) underlying the contract, or holds a
forward contract (or call option) permitting the Fund to buy the same currency
at a price that is (i) no higher than the Fund's price to sell the currency or
(ii) greater than the Fund's price to sell the currency provided the difference
is maintained by the Fund in liquid assets in a segregated account with its
custodian. A forward contract to buy a foreign currency is "covered" if a Fund
holds a forward contract (or put option) permitting the Fund to sell the same
currency at a price that is (i) as high as or higher than the Fund's price to
buy the currency or (ii) lower than the Fund's price to buy the currency
provided the difference is maintained by the Fund in liquid assets in a
segregated account with its custodian.

         OPTIONS. Each Non-Money Market Fund may buy put options and buy call
options and write covered call and secured put options. Such options may relate
to particular securities, securities indices, financial instruments, foreign
currencies or (in the case of the International Fixed Income Fund) the yield
differential between two securities ("yield curve options"), and may or may not
be listed on a domestic or foreign securities exchange and may or may not be
issued by the Options Clearing Corporation. Options trading is a highly
specialized activity which entails greater than


                                      -16-
<PAGE>   109
ordinary investment risk. Options 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.

         A call option for a particular security gives the purchaser of the
option the right to buy, and a writer the obligation to sell, the underlying
security at the stated exercise price prior to the expiration of the option,
regardless of the market price of the security. The premium paid to the writer
is in consideration for undertaking the obligation under the option contract. A
put option for a particular security gives the purchaser the right to sell the
security at the stated exercise price prior to the expiration date of the
option, regardless of the market price of the security. Options on indices and
yield curve options provide the holder with the right to make or receive a cash
settlement upon exercise of the option. With respect to options on indices, the
amount of the settlement will equal 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. With respect to yield curve options, the
amount of the settlement will equal the difference between the yields of
designated securities.

         The Funds 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
Fund owns the instrument underlying the call or has an absolute and immediate
right to acquire that instrument without additional cash consideration (or, if
additional cash consideration is required, cash, U.S. Government securities or
other liquid securities, in such amount are held in a segregated account by its
custodian) upon conversion or exchange of other securities held by it. For a
call option on an index, the option is covered if a Fund maintains with its
custodian a diversified portfolio of securities comprising the index or liquid
assets equal to the contract value. A call option is also covered if a Fund
holds a call on the same instrument 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 Fund in liquid assets in a
segregated account with its custodian. The Funds will write put options only if
they are "secured" by liquid assets maintained in a segregated account by the
Funds' custodian 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 Fixed Income Fund holds another call (or put) option on the
spread between the same two securities and maintains in a segregated account
with its custodian cash or cash equivalents sufficient to cover the Fund's net
liability under the two options. Therefore, the Fund's liability for such a
covered option is generally limited to the difference between the amount of


                                      -17-
<PAGE>   110
the Fund's liability under the option written by the Fund less the value of the
option held by the Fund. Yield curve options may also be covered in such other
manner as may be in accordance with the requirements of the counterparty with
which the option is traded and applicable laws and regulations. Yield curve
options are traded over-the-counter and because they have been only recently
introduced, established trading markets for these securities have not yet
developed.

         A Fund's obligation to sell an instrument subject to a covered call
option written by it, or to purchase an instrument subject to a secured put
option written by it, may be terminated prior to the expiration date of the
option by the Fund'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 instrument, 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 instrument from being
called, to permit the sale of the underlying instrument or to permit the writing
of a new option containing different terms on such underlying instrument. 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 Fund 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 instrument (in the case of a covered call option) or liquidate the
segregated account (in the case of a secured put option) until the option
expires or the optioned instrument 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 instrument during such period.

         When a Fund purchases an option, the premium paid by it is recorded as
an asset of the Fund. When a Fund writes an option, an amount equal to the net
premium (the premium less the commission) received by a Fund is included in the
liability section of the Fund'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 a Fund expires unexercised the Fund realizes a loss equal to the
premium paid. If a Fund enters into a closing sale transaction on an option
purchased by it, the Fund will realize a gain if the premium received by the
Fund 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 a Fund expires on the
stipulated expiration date or if a Fund enters into


                                      -18-
<PAGE>   111
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 a Fund is exercised, the proceeds of the sale will be
increased by the net premium originally received and the Fund will realize a
gain or loss.

         There are several risks associated with transactions in 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 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. The Funds (other than the Money
Market Funds) may purchase and sell futures contracts and may purchase and sell
call and put options on futures contracts. 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 or
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


                                      -19-
<PAGE>   112
the National Futures Association and any domestic exchange, including the right
to use reparations proceedings before the CFTC and arbitration proceedings
provided them by the National Futures Association or any domestic futures
exchange. In particular, the Fund's investments in foreign futures or foreign
options transactions may not be provided the same protections in respect of
transactions on United States futures exchanges. 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. For a detailed description of futures contracts and related options,
see Appendix B to this Additional Statement.

         REAL ESTATE INVESTMENT TRUSTS. The Small Cap Fund may invest in equity
real estate investment trusts ("REITs"). REITs pool investors' funds for
investment primarily in commercial real estate properties. Investments in REITs
may subject the Fund 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 Fund 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 Fund bears
directly in connection with its own operations.

         SECURITIES LENDING. Collateral for loans of portfolio securities made
by a Fund may consist of cash, securities issued or guaranteed by the U.S.
Government or its agencies or (except for the U.S. Government Money Market Fund,
U.S. Government Select Money Market Fund and U.S. Government Fund) 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 Fund 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 Fund if a material event
affecting the investment is to occur.

          INTEREST RATE AND CURRENCY SWAPS.  The U.S. Government, Fixed
Income, Intermediate Tax-Exempt, Tax-Exempt, Florida Intermediate
Tax-Exempt Fund, International Fixed Income and Income Equity Funds


                                      -20-
<PAGE>   113
may enter into interest rate swaps for hedging purposes and not for speculation.
A Fund 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. Interest rate swaps involve the exchange
by a Fund with another party of their respective commitments to pay or receive
interest, such as an exchange of fixed rate payments for floating rate payments.
The International Funds may also enter into currency swaps, which involve the
exchange of the rights of a Fund and another party to make or receive payments
in specific currencies.

         A Fund will only enter into interest rate swaps on a net basis, i.e.
the two payment streams are netted out, with a Fund receiving or paying, as the
case may be, only the net amount of the two payments. In contrast, currency
swaps usually involve the delivery of the entire principal value of one
designated currency in exchange for the other designated currency. Inasmuch as
these transactions are entered into for good faith hedging purposes, the Funds
and Northern Trust believe that such obligations do not constitute senior
securities as defined in the 1940 Act and, accordingly, will not treat them as
being subject to the Funds' borrowing restrictions.

         The net amount of the excess, if any, of the Funds' obligations over
their entitlements with respect to each interest rate swap will be accrued on a
daily basis, and an amount of cash, U.S. Government securities or other liquid
securities, having an aggregate net asset value at least equal to such accrued
excess, will be maintained in a segregated account by the Funds' custodian.

         A Fund will not enter into a currency or interest rate swap 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, a Fund will have contractual remedies pursuant to the agreements
related to the transaction. The swap market has grown substantially in recent
years with a large number of banks and investment banking firms acting both as
principals and as agents utilizing standardized swap documentation. As a result,
the swap market has become relatively liquid in comparison with markets for
other similar instruments which are traded in the Interbank market.

         CONVERTIBLE SECURITIES. Convertible securities entitle the holder to
receive interest paid or accrued on debt or the dividend paid on preferred stock
until the convertible securities mature or are redeemed, converted or exchanged.
Prior to conversion, convertible securities have characteristics similar to
ordinary debt securities in that they normally provide a stable stream of income
with generally higher yields than those of common stock of the same or similar
issuers. Convertible securities rank senior to


                                      -21-
<PAGE>   114
common stock in a corporation's capital structure and therefore generally entail
less risk than the corporation's common stock, although the extent to which such
risk is reduced depends in large measure upon the degree to which the
convertible security sells above its value as a fixed income security.

         In selecting convertible securities for the Fixed Income, Income
Equity, Growth Equity, Select Equity, Small Cap, International Growth Equity,
International Select Equity, International Fixed Income and Technology Funds,
Northern Trust will consider, among other factors: its evaluation of the
creditworthiness of the issuers of the securities; the interest or dividend
income generated by the securities; the potential for capital appreciation of
the securities and the underlying common stocks; the prices of the securities
relative to other comparable securities and to the underlying common stocks;
whether the securities are entitled to the benefits of sinking funds or other
protective conditions; diversification of the Fund's portfolio as to issuers;
and whether the securities are rated by a rating agency and, if so, the ratings
assigned.

         The value of convertible securities is a function of their investment
value (determined by yield in comparison with the yields of other securities of
comparable maturity and quality that do not have a conversion privilege) and
their conversion value (their worth, at market value, if converted into the
underlying common stock). The investment value of convertible securities is
influenced by changes in interest rates, with investment value declining as
interest rates increase and increasing as interest rates decline, and by the
credit standing of the issuer and other factors. The conversion value of
convertible securities is determined by the market price of the underlying
common stock. If the conversion value is low relative to the investment value,
the price of the convertible securities is governed principally by their
investment value. To the extent the market price of the underlying common stock
approaches or exceeds the conversion price, the price of the convertible
securities will be increasingly influenced by their conversion value. In
addition, convertible securities generally sell at a premium over their
conversion value determined by the extent to which investors place value on the
right to acquire the underlying common stock while holding fixed income
securities.

         Capital appreciation for a Fund may result from an improvement in the
credit standing of an issuer whose securities are held in the Fund or from a
general lowering of interest rates, or a combination of both. Conversely, a
reduction in the credit standing of an issuer whose securities are held by a
Fund or a general increase in interest rates may be expected to result in
capital depreciation to the Fund.


                                      -22-
<PAGE>   115
         In general, investments in non-investment grade convertible securities
are subject to a significant risk of a change in the credit rating or financial
condition of the issuing entity. Investments in convertible securities of medium
or lower quality are also likely to be subject to greater market fluctuation and
to greater risk of loss of income and principal due to default than investments
of higher rated fixed-income securities. Such lower-rated securities generally
tend to reflect short-term corporate and market developments to a greater extent
than higher rated securities, which react more to fluctuations in the general
level of interest rates. A Fund will generally reduce risk to the investor by
diversification, credit analysis and attention to current developments in trends
of both the economy and financial markets. However, while diversification
reduces the effect on a Fund of any single investment, it does not reduce the
overall risk of investing in lower rated securities.

         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 Fund'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
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 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 Fund may incur additional
expenses to seek recovery. In addition, periods of economic uncertainty would
likely result in increased volatility


                                      -23-
<PAGE>   116
for the market prices of lower-rated securities as well as a Fund'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 Fund'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
convertible securities held by a Fund, especially in a thinly traded market.
Illiquid or restricted securities held by a Fund may involve special
registration responsibilities, liabilities and costs, and could involve other
liquidity and valuation difficulties.

         Current laws, such as those requiring federally-insured savings and
loan associations to remove investments in lower-rated securities from their
portfolios, as well as other pending proposals, may have a material impact on
the market for lower-rated securities.

         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 agencies may not always
reflect current conditions and events, in addition to using recognized rating
agencies and other sources, Northern Trust performs its own analysis of the
issuers whose lower-rated securities a Fund holds. Because of this, a Fund's
performance may depend more on its adviser's credit analysis than is the case of
mutual funds investing in higher-rated securities.

         INVESTMENT COMPANIES. Each Fund currently intends to limit its
investments in securities issued by other investment companies so that, as
determined immediately after a purchase of such securities is made, not more
than 3% of the outstanding voting stock of any one investment company will be
owned by Northern Funds as a whole and their affiliated persons (as defined in
the 1940 Act). An investment company whose securities are purchased by a Fund is
not obligated to 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 the amount may be illiquid.

         YIELDS AND RATINGS. The yields on certain obligations, including the
money market instruments in which the Funds invest, are dependent on a variety
of factors, including general economic conditions, conditions in the particular
market for the obligation,


                                      -24-
<PAGE>   117
financial condition of the issuer, size of the offering, maturity of the
obligation and ratings of the issue. The ratings of Standard & Poor's, Moody's,
Duff, Fitch and Thomson BankWatch, Inc. 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.

         CALCULATION OF PORTFOLIO TURNOVER RATE. The portfolio turnover rate for
the Funds 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 Funds to receive favorable tax treatment. For the fiscal year ended
March 31, 1996, the turnover rates with respect to the U.S. Government, Fixed
Income, Intermediate Tax-Exempt, Tax-Exempt, International Fixed Income, Income
Equity, Growth Equity, Select Equity, Small Cap, International Growth Equity and
International Select Equity Funds were 112.00%, 116.22%, 137.85%, 60.50%,
52.05%, 67.32%, 73.20%, 137.99%, 46.59%, 216.86% and 176.71%, respectively.
There was a significant variation between the portfolio turnover rates for the
fiscal year ended March 31, 1995 and the fiscal year ended March 31, 1996 for
the Select Equity, U.S. Government, Fixed Income and International Select Equity
Funds due to shareholder purchase/redemption activity, portfolio restructuring
and interest rate fluctuations. The Florida Intermediate Tax-Exempt Fund,
Technology Fund and Stock Index Fund had not commenced operations during the
fiscal year ended March 31, 1996.

         MISCELLANEOUS. The Funds will not normally engage in the trading of
securities for short-term profits. However, the Funds are not restricted by
policy with regard to portfolio turnover and will make changes in their
investment portfolio from time to time as business and economic conditions as
well as market prices may dictate. Securities may be purchased on margin only to
obtain such short-term credits as are necessary for the clearance of purchases
and sales of securities. The Funds will not engage in selling securities short.
The Funds may, however, make short sales against the box although the Funds have
no current intention to do so in the coming year. "Selling short against the
box" involves selling a security that a Fund owns for delivery at a specified
date in the future.

SPECIAL RISK FACTORS AND CONSIDERATIONS RELATING TO CALIFORNIA
MUNICIPAL INSTRUMENTS AND FLORIDA MUNICIPAL INSTRUMENTS

         Some of the risk factors relating to investments by the California
Municipal Money Market Fund in California Municipal Instruments and investments
by the Florida Intermediate Tax-Exempt Fund in Florida Municipal Investments are
summarized below. This summary does not purport to be a comprehensive
description of all relevant factors. Although the Trust has no reason to believe
that the information summarized herein is not correct in all material respects,
this information has not been independently verified for accuracy or
thoroughness by the Trust. Rather, the information presented herein with respect
to California Municipal Instruments was culled from official statements and
prospectuses issued in connection with various securities offerings of the State
of California and local agencies in California available as of the date of this
Statement of Additional Information and, with respect to the Florida
Intermediate Tax-Exempt Fund, the information is derived principally from
official statements relating to issues of Florida Municipal Instruments released
prior to the date of this Additional Statement. Further, any estimates and
projections presented herein should not be construed as statements of fact. They
are based upon assumptions which may be affected by numerous factors and there
can be no assurance that target levels will be achieved.

         CALIFORNIA MUNICIPAL INSTRUMENTS

         ECONOMIC FACTORS. Fiscal Years Prior to 1994-95. By the close of the
1989-90 Fiscal Year California's revenues had fallen below projections, so that
the State's budget reserve, the Special Fund for Economic Uncertainties (the
"Special Fund"), was fully depleted by June 30, 1990. A recession which had
begun in mid-1990, combined with higher health and welfare costs driven by the
State's rapid population growth, adversely affected General Fund revenues, and
raised expenditures above initial budget appropriations.

                  As a result of these factors and others, the State confronted
a period of budget imbalance lasting from the late 1980's through 1992-93.
During this difficult period, expenditures exceeded revenues in four out of six
years, and the State accumulated and sustained a budget deficit in the Special
Fund of nearly $2.8 billion at its peak on June 30, 1993. Thus, beginning with
the 1990-91 Fiscal Year and for each fiscal year thereafter, each budget
required multibillion dollar actions to bring projected revenues and
expenditures into balance. In this context, the Legislature and Governor agreed
on the following principal steps to produce Budget Acts in the years 1991-92 to
1993-94:

                  1. Significant cuts in health and welfare program
expenditures;


                                      -26-
<PAGE>   119
                  2. Transfers of program responsibilities and funding from the
State to local governments (referred to as "realignment"), coupled with some
reduction in mandates on local government;

                  3. Transfer of about $3.6 billion in local property tax
revenues from cities, counties, redevelopment agencies and some other districts
to local school districts, thereby reducing State funding for schools under
Proposition 98;

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

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

                  6. Increased reliance on aid from the federal government to
offset the costs of incarcerating, educating and providing health and welfare
services to illegal immigrants; and

                  7. Various one-time adjustments and accounting changes.

                  Despite these budget actions, the recession still produced
large, unanticipated deficits in the Special Fund. By the 1993-94 Fiscal Year,
the accumulated deficit was too large to be prudently retired in one year, so a
two-year program was implemented which used revenue anticipation warrants to
carry a portion of the deficit over the end of the fiscal year. When the economy
failed to recover sufficiently in 1993-94, a second two-year plan had to be
implemented in 1994-95.

                  Along with other factors such as the disbursement of funds to
local school districts "borrowed" from future fiscal years and hence not shown
in the annual budget, another consequence of the accumulated budget deficits was
to significantly reduce the State's cash resources available to pay its ongoing
obligations. When the Legislature and the Governor failed to adopt a budget for
the 1992-93 Fiscal Year which would have allowed the State to carry out its
normal annual cash flow borrowing to replenish its cash reserves, the State
Controller issued registered warrants to pay a variety of obligations
representing prior years' or continuing appropriations, and mandates from court
orders. Available funds were used to make constitutionally-mandated payments,
such as debt service on bonds and warrants. Between July 1 and September 4, 1992
the State Controller issued a total of approximately $3.8 billion of registered
warrants. After that date, all remaining outstanding registered warrants (about
$2.9 billion) were called for redemption from proceeds of the issuance of 1992
Interim Notes.

                  In late spring of 1992, the State Controller issued revenue
anticipation warrants maturing in the following fiscal year in order to pay the
State's continuing obligations. The State was forced to rely increasingly on

cash needs. Consequently, a succession of notes and warrants were issued in the
period from June 1992 to July 1994 to pay previously maturing notes or warrants.
These borrowings were used in part to spread out the repayment of the
accumulated budget deficit over the end of a fiscal year.

                  A key feature of the 1993-94 Budget Act was a plan to retire
the $2.8 billion budget deficit which had been accumulated by June 30, 1993 (the
"Deficit Retirement Plan"). This 18-month plan used existing statutory authority
to borrow $2.8 billion externally. The 1993-94 Budget Act provided that $1.6
billion of the deficit elimination loan would be repaid by December 23, 1993
from a portion of the proceeds of the $2.0 billion 1993 Revenue Anticipation
Warrants issued on June 23, 1993. Legislation enacted with the 1993-94 Budget
Act directed the State Controller to issue $1.2 billion of registered
reimbursement warrants in the 1993-94 Fiscal Year to fund the balance of the
accumulated deficit. Pursuant to this directive, the State issued $1.2 billion
of 1994 Revenue Anticipation Warrants, Series A (the "Series A Warrants") in
February 1994, which matured on December 21, 1994. The legislation also created
a Deficit Retirement Fund within the State Treasury and the State Controller
transferred $1.2 billion from the General Fund to this Deficit Retirement Fund
to retire the Series A Warrants.

                  The Deficit Retirement Plan was designed to balance the budget
over the 1993-94 and 1994-95 Fiscal Years, and projected a General Fund balance
of $260 million by June 30, 1995. However, fiscal conditions did not improve as
projected and the revenue assumptions of the Deficit Retirement Plan could not
be met. Accordingly, the 1994-95 Budget Act anticipated deferring retirement of
about $1 billion of the carryover budget deficit to the 1995-96 Fiscal Year.
This 22-month Deficit Reduction Plan relied on existing statutory authority to
borrow $4 billion externally, including approximately $1 billion as carryover
budget deficit. In addition, Chapter 136, Statutes of 1994, created in the
Warrant Payment Fund according to which the State Controller was directed to
transfer from the General Fund to the Warrant Payment Fund in four equal
installments the amount necessary to retire the $4.0 billion of revenue
anticipation warrants maturing on April 25, 1996.

                  1994-95 Fiscal Year. The 1994-95 Budget Act, signed by the
Governor on July 8, 1994, projected General Fund revenues and transfers of $41.9
billion -- $2.1 billion more than actual revenues received in 1993-94 -- and
expenditures of $40.9 billion which represented an increase of $1.6 billion over
the prior year.


                  As a result of the improving economy, the Department of
Finance's final estimates for the fiscal year showed revenues and transfers of
$42.7 billion and expenditures of $42.0 billion, thus


                                      -28-
<PAGE>   121
reducing the accumulated budget deficit to about $600 million and reflecting the
Administration's forecast of an improving economy.

                  The principal features of the 1994-95 Budget Act were as
follows:

                  1. Receipt of additional federal aid of about $760 million for
         costs of refugee assistance and costs of incarceration and medical care
         for illegal immigrants. Only about $33 million of this amount was
         received, with about another $98 million scheduled to be received in
         the 1995-96 Fiscal Year;

                  2. Reductions of approximately $1.1 billion in health and
         welfare costs. A 2.3% reduction in Aid to Family with Dependent
         Children payments (equal to about $56 million for the entire fiscal
         year) has been temporarily suspended by court order pending appeal;

                  3. A General Fund increase of approximately $38 million in
         support for the University of California and $65 million for California
         State University, accompanied by student fee increases for both the
         University of California and California State University;

                  4. Proposition 98 funding for K-14 schools was increased by
         $526 million from 1993-94 Fiscal Year levels, representing an increase
         for enrollment growth and inflation. Consistent with previous budget
         agreements, Proposition 98 funding provided approximately $4,217 per
         student for K-12 schools, equal to the level in the prior three years;
         and

                  5. Additional miscellaneous cuts ($500 million), fund
         transfers ($255 million), and adjustment to prior years' legislation
         concerning property tax shifts for local governments ($300 million).

                  The 1994-95 Budget Act contained no tax increases. Under
legislation enacted for the 1993-94 Budget Act, the renters' tax credit was
suspended for two years (1993 and 1994). The Legislature enacted a further
one-year suspension of the renters' tax credit, for 1995, saving about $390
million in the 1995-96 Fiscal Year.

                  The State's cash flow management plan for the 1994-95 Fiscal
Year included the issuance of $4.0 billion of Revenue Anticipation Warrants,
Series C and D, to mature on April 25, 1996, as part of a two-year plan to
retire the accumulated State budget deficit. To assure repayment of these
warrants, the Legislature enacted a backup mechanism which could result in
automatic expenditure cuts if projected revenues did not meet certain targets
(the "Budget Adjustment Law").


                                      -29-
<PAGE>   122
                  The third and last step in the Budget Adjustment Law process
occurred on October 16, 1995, when the State Controller issued a report (the
"October Trigger Report") reviewing the estimated cash condition of the General
Fund for the 1995-96 Fiscal Year. The State Controller estimated that the
General Fund would have at least $1.4 billion of internal cash resources on June
30, 1996. Put another way, external borrowing would not be needed on June 30,
1996. As a result of this finding, certain provisions of the Budget Adjustment
Law, which could have ultimately led to automatic, across-the-board cuts in the
General Fund budget, will not have to be implemented. Likewise, an earlier
report issued on November 15, 1994, avoided implementation of any automatic
budget cuts in the 1994-95 fiscal year.

                  1995-96 Fiscal Year. With strengthening revenues and reduced
caseload growth based on an improving economy, the State entered the 1995-96
Fiscal Year budget negotiations with the smallest nominal "budget gap" to be
closed in many years. Nonetheless, serious policy differences between the
Governor and Legislature prevented timely enactment of the budget. The 1995-96
Budget Act was signed by the Governor on August 3, 1995, 34 days after the start
of the fiscal year. The Budget Act projected General Fund revenues and transfers
of $44.1 billion, a 3.5 percent increase from the prior year. Expenditures were
budgeted at $43.4 billion, a 4 percent increase. The Department of Finance
projected that after repaying the last of the carryover budget deficit, there
would be a positive balance of $28 million in the budget reserve on June 30,
1996. The Budget Act also projected Special Fund revenues of $12.7 billion and
appropriated Special Fund expenditures of $13.0 billion.

                  The following are the principal features of the 1995-96 Budget
Act:

                  1. Proposition 98 funding for schools and community colleges
         was originally budgeted to increase by about $1.0 billion (General
         Fund) and $1.2 billion total above revised 1994-95 levels. Because of
         higher than projected revenues in 1994-95, an additional $543 million
         ($91 per K-12 ADA) was appropriated to the 1994-95 Proposition 98
         entitlement. A large part of this is a block grant of about $54 per
         pupil for any onetime purpose. For the first time in several years, a
         full 2.7 percent cost of living allowance was funded. The budget
         compromise anticipates a settlement of the CTA v. Gould litigation
         (discussed below). The Governor's 1996-97 Budget indicates that, with
         revenues even higher than projected, Proposition 98 apportionments will
         exceed the amounts originally budgeted, reaching a level of $4,500 per
         ADA;

                  2. Cuts in health and welfare costs totaling about $0.9
         billion. Some of these cuts (totaling about $500 million)

                  
                                      -30-
<PAGE>   123
         require federal legislative or administrative approval, which was still
         pending as of January 1996.

                  3. A 3.5 percent increase in funding for the University of
         California ($90 million General Fund) and the California State
         University system ($24 million General Fund), with no increases in
         student fees;

                  4. The Budget assumed receipt of $473 million in new federal
         aid for costs of illegal immigrants, above commitments already made by
         the federal government. In the Governor's 1996-97 Budget, the
         Administration revised this figure downward to $278 million; and

                  5. General Fund support for the Department of Corrections is
         increased by about eight percent over the prior year, reflecting
         estimates of increased prison population, but funding is less than
         proposed in the 1995 Governor's Budget.

                  The Governor's Budget for the 1996-97 Fiscal Year, released on
January 10, 1996, updated the current year projections, so that revenues and
transfers are estimated to be $45.0 billion, and expenditures to be $44.2
billion. The Special Fund was projected to have a positive balance of about $50
million at June 30, 1996, and on that date available internal borrowable
resources (available cash, after payment of all obligations due) will be about
$2.2 billion. The Administration projected it would issue up to $2.0 billion of
revenue anticipation notes to mature by June 30, 1996 to assist in cash flow
management for the final two months of the year.

                  1996-97 Fiscal Year. On January 10, 1996, the Governor
released his proposed budget for the next fiscal year (the "1996-97 Budget").
Based on projected revenues and transfers of about $45.6 billion, the Governor
requested total General Fund appropriations of about $45.2 billion which would
create a $400 million budget reserve in the Special Fund at June 30, 1997. The
Governor renewed a proposal for a 15 percent phased cut in individual and
corporate tax rates over three years (the budget proposal assumes this will be
enacted, reducing revenues in 1996-97 by about $600 million). There was also a
proposal to restructure trial court funding in a way which would result in a
$300 million decrease in General Fund revenues. The Governor requested
legislation to make permanent a moratorium on cost of living increases for
welfare payments, and suspension of a renters tax credit, which otherwise would
go back into effect in the 1996-97 Fiscal Year. He further proposed additional
costs in certain health and welfare programs, and assumed that costs previously
approved by the Legislature will receive federal approval. The Governor's Budget
proposed increases in funding for K-12 schools under Proposition 98, for State
higher education systems (with a second year of no student fee increases),


                                      -31-
<PAGE>   124
and for corrections. The Governor's Budget projects external cash flow borrowing
of up to $3.2 billion, to mature by June 30, 1997.

                  The Orange County Bankruptcy. On December 6, 1994, Orange
County, California and its Investment Pool (the "Pool") filed for bankruptcy
under Chapter 9 of the United States Bankruptcy Code. Approximately 187
California public entities, substantially all of which are public agencies
within the County, invested funds in the Pool. Many of the agencies have various
bonds, notes or other forms of indebtedness outstanding, in some instances the
proceeds of which were invested in the Pool. Various investment advisors were
employed by the County to restructure the Pool. Such restructuring led to the
sale of substantially all of the Pool's portfolio, resulting in losses estimated
to be approximately $1.7 billion or approximately 22% of amounts deposited by
the Pool investors, including the County. It is anticipated that such losses may
result in delays or failures of the County as well as investors in the Pool to
make scheduled debt service payments. Further, the County expects substantial
budget deficits to occur in Fiscal Year 1995 with possibly similar effects upon
operations of investors in the Pool.

                  Investor access to monies in the Pool subsequent to the filing
was pursuant to Court order only and severely limited. On May 2, 1995, the
Bankruptcy Court approved a comprehensive settlement agreement (the "CSA")
between the County and Pool investors which, among other things, (i) established
a formula for distribution of all available cash and securities from the Pool to
the Pool investors, including the County, (ii) established formulas for
distribution among certain settling Pool investors of several tranches of new
County obligations to be payable from, and in some instances secured by, certain
designated sources of potential recoveries on Pool related claims, and (iii)
designated certain outstanding short term note obligations of the County to be
senior to or on a parity with certain of the new County obligations. By order
dated May 22, 1995, following distribution of all available cash and securities
from the Pool to the Pool investors, including the County, the Bankruptcy Court
dismissed the bankruptcy filing of the Pool based upon the Court's finding that
the Pool was not eligible for relief under Chapter 9 of the Bankruptcy Code
because it is not a municipality and it has not been specifically authorized to
file under Chapter 9 as required by the Bankruptcy Code.

                  On or about June 12, 1996 a plan of adjustment previously
confirmed by the bankruptcy court became effective for the County. Pursuant to
the plan, publicly held debt is to be paid in full, with municipal investors in
the Pool retaining an interest in litigation claims against third parties. The
plan was funded in substantial part by the sale of $900 million in new County
securities, securitizing substantially all unencumbered assets previously held
by the County.

                  CONSTITUTIONAL, LEGISLATIVE AND OTHER FACTORS. Certain
California constitutional amendments, legislative measures, executive orders,
administrative regulations and voter initiatives could result in the adverse
effects described below.

                  Revenue Distribution. Certain California Municipal Instruments
may be obligations of issuers which rely in whole or in part on California State
revenues for payment of these obligations. Property tax revenues and a portion
of the State's general fund surplus are distributed to counties, cities and
their various taxing entities and the State assumes certain obligations
theretofore paid out of local funds. Whether and to what extent a portion of the
State's general fund will be distributed in the future to counties, cities and
their various entities is unclear.

                  Senate Bill 671. In 1988, California enacted legislation
providing for a water's-edge combined reporting method if an election fee was
paid and other conditions met. On October 6, 1993, the Governor signed Senate
Bill 671 (Alquist) which modifies the unitary tax law by deleting the
requirements that a taxpayer electing to determine its income on a water's-edge
basis pay a fee and file a domestic disclosure spreadsheet and instead requiring
an annual information return. Significantly, the Franchise Tax Board can no
longer disregard a taxpayer's election. The Franchise Tax Board is reported to
have estimated state revenue losses from the Legislation as growing from $27
million in 1993-94 to $616 million in 1999-2000, but others, including Former
Assembly Speaker Willie Brown, disagreed with that estimate and asserted that
more revenue will be generated for California, rather than less, because of an
anticipated increase in economic activity and additional revenue generated by
the incentives in the Legislation.

                  Proposition 13. Certain California Municipal Instruments may
be obligations of issuers who rely in whole or in part on ad valorem real
property taxes as a source of revenue. On June 6, 1978, California voters
approved an amendment to the California Constitution known as Proposition 13,
which added Article XIIIA to the California Constitution. The effect of Article
XIIIA was to limit ad valorem taxes on real property and to restrict the ability
of taxing entities to increase real property tax revenues. On November 7, 1978,
California voters approved Proposition 8, and on June 3, 1986, the California
voters approved Proposition 46, both of which amended Article XIIIA.

                  Section 1 of Article XIIIA limits the maximum ad valorem tax
on real property to 1% of full cash value (as defined in Section 2), to be
collected by the counties and apportioned according to law; provided that the 1%
limitation does not apply to ad valorem taxes or special assessments to pay the
interest and redemption charges on (i) any indebtedness approved by the voters
prior to July 1, 1978, or (ii) any bonded indebtedness for the acquisition or
improvement of real property approved on or after


                                      -33-
<PAGE>   126
July 1, 1978, by two-thirds of the votes cast by the voters voting on the
proposition. Section 2 of Article XIIIA defines "full cash value" to mean "the
County Assessor's valuation of real property as shown on the 1975/76 tax bill
under `full cash value' or, thereafter, the appraised value of real property
when purchased, newly constructed, or a change in ownership has occurred after
the 1975 assessment." The full cash value may be adjusted annually to reflect
inflation at a rate not to exceed 2% per year, or reduction in the consumer
price index or comparable local data, or reduced in the event of declining
property value caused by damage, destruction or other factors. The California
State Board of Equalization has adopted regulations, binding on county
assessors, interpreting the meaning of "change in ownership" and "new
construction" for purposes of determining full cash value of property under
Article XIIIA.

                  Legislation enacted by the California Legislature to implement
Article XIIIA (Statutes of 1978, Chapter 292, as amended) provides that
notwithstanding any other law, local agencies may not levy any ad valorem
property tax except to pay debt service on indebtedness approved by the voters
prior to July 1, 1978, and that each county will levy the maximum tax permitted
by Article XIIIA of $4.00 per $100 assessed valuation (based on the former
practice of using 25%, instead of 100%, of full cash value as the assessed value
for tax purposes). The legislation further provided that, for the 1978/79 fiscal
year only, the tax levied by each county was to be apportioned among all taxing
agencies within the county in proportion to their average share of taxes levied
in certain previous years. The apportionment of property taxes for fiscal years
after 1978/79 has been revised pursuant to Statutes of 1979, Chapter 282, which
provides relief funds from State moneys beginning in fiscal year 1979/80 and is
designed to provide a permanent system for sharing State taxes and budget funds
with local agencies. Under Chapter 282, cities and counties receive more of the
remaining property tax revenues collected under Proposition 13 instead of direct
State aid. School districts receive a correspondingly reduced amount of property
taxes, but receive compensation directly from the State and are given additional
relief. Chapter 282 does not affect the derivation of the base levy ($4.00 per
$100 assessed valuation) and the bonded debt tax rate.

                  Proposition 9. On November 6, 1979, an initiative known as
"Proposition 9" or the "Gann Initiative" was approved by the California voters,
which added Article XIIIB to the California Constitution. Under Article XIIIB,
State and local governmental entities have an annual "appropriations limit" and
are not allowed to spend certain moneys called "appropriations subject to
limitation" in an amount higher than the "appropriations limit." Article XIIIB
does not affect the appropriation of moneys which are excluded from the
definition of "appropriations subject to limitation," including debt service on
indebtedness existing or


                                      -34-
<PAGE>   127
authorized as of January 1, 1979, or bonded indebtedness subsequently approved
by the voters. In general terms, the "appropriations limit" is required to be
based on certain 1978/79 expenditures, and is to be adjusted annually to reflect
changes in consumer prices, population and certain services provided by these
entities. Article XIIIB also provides that if these entities' revenues in any
year exceed the amounts permitted to be spent, the excess is to be returned by
revising tax rates or fee schedules over the subsequent two years.

                  Article XIIIB, like Article XIIIA, may require further
interpretation by both the Legislature and the courts to determine its
applicability to specific situations involving the State and local taxing
authorities. Depending upon the interpretation, Article XIIIB may limit
significantly a governmental entity's ability to budget sufficient funds to meet
debt service on bonds and other obligations.

                  Proposition 98. On November 8, 1988, voters of the State
approved Proposition 98, a combined initiative constitutional amendment and
statute called the "Classroom Instructional Improvement and Accountability Act."
Proposition 98 changed State funding of public education below the university
level and the operation of the State Appropriations Limit, primarily by
guaranteeing K-14 schools a minimum share of General Fund revenues. Under
Proposition 98 (modified by Proposition 111 as discussed below), K-14 schools
are guaranteed the greater of (a) in general, a fixed percent of General Fund
revenues ("Test 1"), (b) the amount appropriated to K-14 schools in the prior
year, adjusted for changes in the cost of living (measured as in Article XIIIB
by reference to State per capita personal income) and enrollment ("Test 2"), or
(c) a third test, which would replace Test 2 in any year when the percentage
growth in per capita General Fund revenues from the prior year plus one half of
one percent is less than the percentage growth in State per capita personal
income ("Test 3"). Under Test 3, schools would receive the amount appropriated
in the prior year adjusted for changes in enrollment and per capita General Fund
revenues, plus an additional small adjustment factor. If Test 3 is used in any
year, the difference between Test 3 and Test 2 would become a "credit" to
schools which would be the basis of payments in future years when per capital
General Fund revenue growth exceeds per capita personal income growth.
Legislation adopted prior to the end of the 1988-89 Fiscal Year, implementing
Proposition 98, determined the K-14 schools' funding guarantee under Test 1 to
be 40.3 percent of the General Fund tax revenues, based on 1986-87
appropriations. However, that percent has been adjusted to approximately 35
percent to account for a subsequent redirection of local property taxes, since
such redirection directly affects the share of General Fund revenues to schools.



                                      -35-
<PAGE>   128
                  Proposition 98 permits the Legislature by two-thirds vote of
both houses, with the Governor's concurrence, to suspend the K-14 schools'
minimum funding formula for a one-year period. Proposition 98 also contains
provisions transferring certain State tax revenues in excess of the Article
XIIIB limit to K-14 schools.

                  During the recent recession, General Fund revenues for several
years were less than originally projected, so that the original Proposition 98
appropriations turned out to be higher than the minimum percentage provided in
the law. The Legislature responded to these developments by designating the
"extra" Proposition 98 payments in one year as a "loan" from future years'
Proposition 98 entitlements, and also intended that the "extra" payments would
not be included in the Proposition 98 "base" for calculating future years'
entitlements. By implementing these actions, per-pupil funding from Proposition
98 sources stayed almost constant at approximately $4,220 from Fiscal Year
1991-92 to Fiscal Year 1993-94.

                  In 1992, a lawsuit was filed, California Teachers' Association
v. Gould, which challenged the validity of these off-budget loans. As part of
the negotiations leading to the 1995-96 Budget Act, an oral agreement was
reached to settle this case. It is expected that a formal settlement reflecting
these conditions will be entered into in the near future.

                  The oral agreement provides that both the State and K-14
schools share in the repayment of prior years' emergency loans to schools. Of
the total $1.76 billion in loans, the State will repay $935 million, while
schools will repay $825 million. The State share of the repayment will be
reflected as expenditures above the current Proposition 98 base circulation. The
schools' share of the repayment will count as appropriations that count toward
satisfying the Proposition 98 guarantee, or from "below" the current base.
Repayments are spread over the eight-year period of 1994-95 through 2001-02 to
mitigate any adverse fiscal impact. Once a court settlement is reached, and the
Director of Finance certifies that such a settlement has occurred, approximately
$377 million in appropriations from the 1995-96 Fiscal Year to schools will be
disbursed in August 1996.

                  Proposition 111. On June 30, 1989, the California Legislature
enacted Senate Constitutional Amendment 1, a proposed modification of the
California Constitution to alter the spending limit and the education funding
provisions of Proposition 98. Senate Constitutional Amendment 1, on the June 5,
1990 ballot as Proposition 111, was approved by the voters and took effect on
July 1, 1990. Among a number of important provisions, Proposition 111
recalculates spending limits for the State and for local governments, allows
greater annual increases in the limits, allows the averaging of two years' tax
revenues before requiring action regarding excess tax revenues, reduces the
amount of the funding


                                      -36-
<PAGE>   129
guarantee in recession years for school districts and community college
districts (but with a floor of 40.9 percent of State general fund tax revenues),
removes the provision of Proposition 98 which included excess moneys transferred
to school districts and community college districts in the base calculation for
the next year, limits the amount of State tax revenue over the limit which would
be transferred to school districts and community college districts, and exempts
increased gasoline taxes and truck weight fees from the State appropriations
limit. Additionally, Proposition 111 exempts from the State appropriations limit
funding for capital outlays.

                  Proposition 62. On November 4, 1986, California voters
approved an initiative statute known as Proposition 62. This initiative provides
the following: (i) requires that any tax for general governmental purposes
imposed by local governments be approved by resolution or ordinance adopted by a
two-thirds vote of the governmental entity's legislative body and by a majority
vote of the electorate of the governmental entity, (ii) requires that any
special tax (defined as taxes levied for other than general governmental
purposes) imposed by a local governmental entity be approved by a two-thirds
vote of the voters within that jurisdiction, (iii) restricts the use of revenues
from a special tax to the purposes or for the service for which the special tax
was imposed, (iv) prohibits the imposition of ad valorem taxes on real property
by local governmental entities except as permitted by Article XIIIA, (v)
prohibits the imposition of transaction taxes and sales taxes on the sale of
real property by local governments, (vi) requires that any tax imposed by a
local government on or after August 1, 1985 be ratified by a majority vote of
the electorate within two years of the adoption of the initiative or be
terminated by November 15, 1988, (vii) requires that, in the event a local
government fails to comply with the provisions of this measure, a reduction in
the amount of property tax revenue allocated to such local government occurs in
an amount equal to the revenues received by such entity attributable to the tax
levied in violation of the initiative, and (viii) permits these provisions to be
amended exclusively by the voters of the State of California.

                  In September 1988, the California Court of Appeal in City of
Westminster v. County of Orange, 204 Cal. App. 3d 623, 215 Cal. Rptr. 511 (Cal.
Ct. App. 1988), held that Proposition 62 is unconstitutional to the extent that
it requires a general tax by a general law city, enacted on or after August 1,
1985 and prior to the effective date of Proposition 62, to be subject to
approval by a majority of voters. The Court held that the California
Constitution prohibits the imposition of a requirement that local tax measures
be submitted to the electorate by either referendum or initiative. It is not
possible to predict the impact of this decision on charter cities, on special
taxes or on new taxes imposed after the effective date of Proposition 62.

                  Proposition 87. On November 8, 1988, California voters
approved Proposition 87. Proposition 87 amended Article XVI, Section 16, of the
California Constitution by authorizing the California Legislature to prohibit
redevelopment agencies from receiving any of the property tax revenue raised by
increased property tax rates levied to repay bonded indebtedness of local
governments which is approved by voters on or after January 1, 1989. It is
impossible to predict whether the California Legislature will enact such a
prohibition nor is it possible to predict the impact of Proposition 87 on
redevelopment agencies and their ability to make payments on outstanding debt
obligations.

                  Health Care Legislation. Certain California Municipal
Instruments may be obligations which are payable solely from the revenues of
health care institutions. Certain provisions under California law may adversely
affect these revenues and, consequently, payment on those Municipal Instruments.

                  The federally sponsored Medicaid program for health care
services to eligible welfare beneficiaries in California is known as the
Medi-Cal program. Historically, the Medi-Cal program has provided for a
cost-based system of reimbursement for inpatient care furnished to Medi-Cal
beneficiaries by any hospital wanting to participate in the Medi-Cal program,
provided such hospital met applicable requirements for participation. California
law now provides that the State of California shall selectively contract with
hospitals to provide acute inpatient services to Medi-Cal patients. Medi-Cal
contracts currently apply only to acute inpatient services. Generally, such
selective contracting is made on a flat per diem payment basis for all services
to Medi-Cal beneficiaries, and generally such payment has not increased in
relation to inflation, costs or other factors. Other reductions or limitations
may be imposed on payment for services rendered to Medi-Cal beneficiaries in the
future.

                  Under this approach, in most geographical areas of California,
only those hospitals which enter into a Medi-Cal contract with the State of
California will be paid for non-emergency acute inpatient services rendered to
Medi-Cal beneficiaries. The State may also terminate these contracts without
notice under certain circumstances and is obligated to make contractual payments
only to the extent the California legislature appropriates adequate funding
therefor.

                  California enacted legislation in 1982 that authorizes private
health plans and insurers to contract directly with hospitals for services to
beneficiaries on negotiated terms. Some insurers have introduced plans known as
"preferred provider organizations" ("PPOs"), which offer financial incentives
for subscribers who use only the hospitals which contract with the plan. Under
an exclusive provider plan, which includes most health maintenance organizations
("HMOs"), private payors limit coverage


                                      -38-
<PAGE>   131
to those services provided by selected hospitals. Discounts offered to HMOs and
PPOs may result in payment to the contracting hospital of less than actual cost
and the volume of patients directed to a hospital under an HMO or PPO contract
may vary significantly from projections. Often, HMO or PPO contracts are
enforceable for a stated term, regardless of provider losses or of bankruptcy of
the respective HMO or PPO. It is expected that failure to execute and maintain
such PPO and HMO contracts would reduce a hospital's patient base or gross
revenues. Conversely, participation may maintain or increase the patient base,
but may result in reduced payment and lower net income to the contracting
hospitals.

                  These California Municipal Instruments may also be insured by
the State of California pursuant to an insurance program implemented by the
Office of Statewide Health Planning and Development for health facility
construction loans. If a default occurs on insured California Municipal
Instruments, the State Treasurer will issue debentures payable out of a reserve
fund established under the insurance program or will pay principal and interest
on an unaccelerated basis from unappropriated State funds. At the request of the
Office of Statewide Health Planning and Development, Arthur D. Little, Inc.
prepared a study in December 1983, to evaluate the adequacy of the reserve fund
established under the insurance program and based on certain formulations and
assumptions found the reserve fund substantially underfunded. In September of
1986, Arthur D. Little, Inc. prepared an update of the study and concluded that
an additional 10% reserve be established for "multi-level" facilities. For the
balance of the reserve fund, the update recommended maintaining the current
reserve calculation method. In March of 1990, Arthur D. Little, Inc. prepared a
further review of the study and recommended that separate reserves continue to
be established for "multi-level" facilities at a reserve level consistent with
those that would be required by an insurance company.

                  Mortgages and Deeds. Certain California Municipal Instruments
may be obligations which are secured in whole or in part by a mortgage or deed
of trust on real property. California has five principal statutory provisions
which limit the remedies of a creditor secured by a mortgage or deed of trust.
Two provisions limit the creditor's right to obtain a deficiency judgment, one
limitation being based on the method of foreclosure and the other on the type of
debt secured. Under the former, a deficiency judgment is barred when the
foreclosure is accomplished by means of a nonjudicial trustee's sale. Under the
latter, a deficiency judgment is barred when the foreclosed mortgage or deed of
trust secures certain purchase money obligations. Another California statute,
commonly known as the "one form of action" rule, requires creditors secured by
real property to exhaust their real property security by foreclosure before
bringing a personal action against the debtor. The fourth statutory provision
limits any deficiency


                                      -39-
<PAGE>   132
judgment obtained by a creditor secured by real property following a judicial
sale of such property to the excess of the outstanding debt over the fair value
of the property at the time of the sale, thus preventing the creditor from
obtaining a large deficiency judgment against the debtor as the result of low
bids at a judicial sale. The fifth statutory provision gives the debtor the
right to redeem the real property from any judicial foreclosure sale as to which
a deficiency judgment may be ordered against the debtor.

                  Upon the default of a mortgage or deed of trust with respect
to California real property, the creditor's nonjudicial foreclosure rights under
the power of sale contained in the mortgage or deed of trust are subject to the
constraints imposed by California law upon transfers of title to real property
by private power of sale. During the three-month period beginning with the
filing of a formal notice of default, the debtor is entitled to reinstate the
mortgage by making any overdue payments. Under standard loan servicing
procedures, the filing of the formal notice of default does not occur unless at
least three full monthly payments have become due and remain unpaid. The power
of sale is exercised by posting and publishing a notice of sale for at least 20
days after expiration of the three-month reinstatement period. The debtor may
reinstate the mortgage, in the manner described above, up to five business days
prior to the scheduled sale date. Therefore, the effective minimum period for
foreclosing on a mortgage could be in excess of seven months after the initial
default. Such time delays in collections could disrupt the flow of revenues
available to an issuer for the payment of debt service on the outstanding
obligations if such defaults occur with respect to a substantial number of
mortgages or deeds of trust securing an issuer's obligations.

                  In addition, a court could find that there is sufficient
involvement of the issuer in the nonjudicial sale of property securing a
mortgage for such private sale to constitute "state action," and could hold that
the private-right-of-sale proceedings violate the due process requirements of
the federal or state constitutions, consequently preventing an issuer from using
the nonjudicial foreclosure remedy described above.

                  Certain California Municipal Instruments may be obligations
which finance the acquisition of single family home mortgages for low and
moderate income mortgagors. These obligations may be payable solely from
revenues derived from the home mortgages, and are subject to California's
statutory limitations described above applicable to obligations secured by real
property. Under California antideficiency legislation, there is no personal
recourse against a mortgagor of a single family residence purchased with the
loan secured by the mortgage, regardless of whether the creditor chooses
judicial or nonjudicial foreclosure.


                                      -40-
<PAGE>   133
                  Under California law, mortgage loans secured by single-family
owner-occupied dwellings may be prepaid at any time. Prepayment charges on such
mortgage loans may be imposed only with respect to voluntary prepayments made
during the first five years during the term of the mortgage loan, and then only
if the borrower prepays an amount in excess of 20% of the original principal
amount of the mortgage loan in a 12-month period; a prepayment charge cannot in
any event exceed six months' advance interest on the amount prepaid during the
12-month period in excess of 20% of the original principal amount of the loan.
This limitation could affect the flow of revenues available to an issuer for
debt service on the outstanding debt obligations which financed such home
mortgages.

         FLORIDA MUNICIPAL INSTRUMENTS

         The financial condition of the State of Florida may be affected by
various financial, social, economic and political factors. Those factors can be
very complex, may vary from fiscal year to fiscal year, and are frequently the
result of actions taken not only by the State and its agencies and
instrumentalities but also by entities that are not under the control of the
State. Adverse developments affecting the State's financing activities, its
agencies or its political subdivisions could adversely affect the State's
financial condition.

         The State's revenues increased from $29,115,034,000 during the 1993-94
fiscal year ended June 30, 1994 to $31,178,025,000 during the fiscal year ended
June 30, 1995. The State's expenses increased from $27,878,146,000 during the
1993-94 fiscal year ended June 30, 1994 to $30,775,597,000 during the 1994-95
fiscal year ended June 30, 1995. The Florida Comptroller also projected
non-agricultural jobs to gross 3.2% and 3.0% in fiscal years 1995-96 and
1996-97, respectively.

         The Constitution of the State of Florida limits the right of the State
and its local governments to tax. The Constitution requires the State to have a
balanced budget and to raise revenues to defray its operating expenses. The
State may not borrow for the purpose of maintaining ordinary operating expenses,
but may generally borrow for capital improvements.

         There are a number of methods by which the State of Florida may incur
debt. The State may issue bonds backed by the State's full faith and credit to
finance or refinance certain capital projects authorized by its voters. The
State also may issue certain bonds backed by the State's full faith and credit
to finance or refinance pollution control, solid waste disposal and water
facilities for local governments, county roads, school districts and capital
public education projects without voter authorization. The State may also,
pursuant to specific constitutional authorization, directly guarantee certain


                                      -41-
<PAGE>   134
obligations of the State's authorities, agencies and instrumentalities. Payments
of debt service on State bonds backed by the State's full faith and credit and
State-guaranteed bonds and notes are legally enforceable obligations of the
State. Revenue bonds to finance or refinance certain capital projects also may
be issued by the State of Florida without voter authorization. However, revenue
bonds are payable solely from funds derived directly from sources other than
state tax revenues.

         The State of Florida currently imposes, among other taxes, an ad
valorem tax on intangible property and a corporate income tax. The Florida
Constitution prohibits the levying of a personal income tax. Certain other taxes
the State of Florida imposes include: an estate or inheritance tax which is
limited by the State's Constitution to an amount not in excess of the amount
allowed to be credited upon or deducted from federal estate taxes or the estate
taxes of another state; and a 6% sales tax on most goods and certain services
with an option for counties to impose up to an additional 1% sales tax on such
goods and services.

         The Constitution reserves the right to charge an ad valorem tax on real
estate and tangible personal property to Florida's local governments. All other
forms of taxation are preempted to the State of Florida except as may be
provided by general law. Motor vehicles, boats, airplanes, trailers, trailer
coaches and mobile homes, as defined by law, may be subject to a license tax for
their operation, but may not be subject to an ad valorem tax.

         Under the Constitution, ad valorem taxes may not be levied in excess of
the following millage upon the assessed value of real estate and tangible
personal property: for all county purposes, ten mills; for all municipal
purposes, ten mills; for all school purposes, ten mills; for water management
purposes for the northwest portion of the State, .05 mills; for water management
purposes for the remaining portion of the State, one mill; and for all other
special districts a millage authorized by law and approved by referendum. When
authorized by referendum, the above millage caps may be exceeded for up to two
years. Counties, school districts, municipalities, special districts and local
governmental bodies with taxing powers may issue bonds to finance or refinance
capital projects payable from ad valorem taxes in excess of the above millage
cap when approved by referendum. It should be noted that several municipalities
and counties have charters that further limit either ad valorem taxes or the
millage that may be assessed.

         The Florida legislature has passed a number of mandates which limit or
place requirements on local governments without providing the local governments
with compensating changes in their fiscal resources. The Florida legislature
enacted a comprehensive growth management act which forces local governments to
establish and implement comprehensive planning programs to guide and control
future development. This legislation prohibits public or private


                                      -42-
<PAGE>   135
development that does not conform with the locality's comprehensive plan. Local
governments may face greater requirements for services and capital expenditures
than they had previously experienced if their locality experiences increased
growth or development. The burden for funding these potential services and
capital expenditures which has been left to the local governments may be quite
large.

         The State of Florida enacted an amendment to the Florida Constitution
("Amendment 10") which limits ad valorem taxes on homestead real property,
effective as of January 1994. Beginning in 1995, Amendment 10 limits the
assessed value of homestead real property for ad valorem tax purposes to the
lower of (A) three percent (3%) of the assessed value for the prior year; or (B)
the percentage change in the Consumer Price Index for the preceding calendar
year. In addition, no such assessed value shall exceed "just value" and such
just value shall be reassessed (notwithstanding the 3% cap) as of January 1 of
the year following a change of ownership of the assessed real property.

         The payment on most Florida Municipal Instruments held by the Florida
Intermediate Tax-Exempt Fund will depend upon the issuer's ability to meet its
obligations. If the State or any of its political subdivisions were to suffer
serious financial difficulties jeopardizing their ability to pay their
obligations, the marketability of obligations issued by the State or localities
within the State, and the value of the Florida Intermediate Tax-Exempt Fund's
portfolio, could be adversely affected.

         OTHER INFORMATION ON CALIFORNIA AND FLORIDA MUNICIPAL
         INSTRUMENTS

         Northern Trust believes that it is likely that sufficient California
and Florida Municipal Instruments and certain specified federal obligations
should be available to satisfy the respective investment objectives, policies
and limitations of the California Municipal Money Market Fund and the Florida
Intermediate Tax-Exempt Fund, and with respect to the California Municipal Money
Market Fund, to enable that Fund to invest at least 50% of its assets in
California Municipal Instruments. If Northern Funds' Board of Trustees, after
consultation with Northern Trust, should for any reason determine that it is
impracticable to satisfy either Fund's investment objective, policies and
limitations, or with respect to the California Municipal Money Market Fund, to
invest at least 50% of its assets in California Municipal Instruments and such
federal obligations at the close of each fiscal quarter, the Board would
re-evaluate the particular Fund's investment objective and policies and consider
changes in its structure and name or possible dissolution.

INVESTMENT RESTRICTIONS

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

No Fund may:

                  (1) Make loans, except (a) through the purchase of debt
         obligations in accordance with the Fund'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 or real estate limited
         partnerships, but this restriction shall not prevent a Fund 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 or leases,
         except that each Fund may, to the extent appropriate to its investment
         policies, purchase securities of companies engaging in whole or in part
         in such activities, and (other than the Money Market Funds) may enter
         into futures contracts and related options and forward currency
         exchange 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 Fund may be
         deemed to be an underwriter under the Securities Act of 1933 (the "1933
         Act") 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; futures contracts; options on
         futures contracts; forward currency exchange contracts; short sales
         against the box; interest rate and currency swaps; and pair-off
         transactions.


                                      -44-
<PAGE>   137
                  (8) Purchase the securities of any issuer if such purchase
         would cause more than 10% of the voting securities of such issuer to be
         held by the Fund, except that up to 25% of the value of its total
         assets may be invested without regard to this 10% limitation; provided
         that this restriction does not apply to the International Fixed Income
         Fund or the Florida Intermediate Tax-Exempt Fund.

         In addition, as summarized in the Prospectus, no Fund may:

                  (9) Purchase securities (other than obligations issued or
         guaranteed by the U.S. Government, its agencies or instrumentalities
         and repurchase agreements collateralized by such obligations) if,
         except for the Technology Fund, such purchase would cause 25% or more
         in the aggregate of the market value of the total assets of the Fund to
         be invested in the securities of one or more issuers having their
         principal business activities in the same industry, provided that with
         respect to each Money Market Fund there is no limitation, and each
         Money Market Fund reserves freedom of action, when otherwise consistent
         with its investment policies, to concentrate its investments in
         obligations (other than commercial paper) issued or guaranteed by U.S.
         banks (including foreign branches of U.S. banks) and U.S. branches of
         foreign banks and repurchase agreements and securities loans
         collateralized by 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. The Technology Fund may not, except
         during temporary defensive periods, purchase the securities of any
         issuer, if, as a result of such purchase, less than 25% of the assets
         of the Technology Fund would be invested in the securities of issuers
         principally engaged in technology business activities.

                  (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 a Fund's total assets or (b)
         from banks, provided that immediately after any such borrowing all
         borrowings of the Fund do not exceed one-third of the Fund's total
         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 a Fund by enabling
         Northern Funds to meet redemption requests when the liquidation of
         portfolio instruments is deemed to be


                                      -45-
<PAGE>   138
         disadvantageous or not possible. If due to market fluctuations or other
         reasons the total assets of a Fund fall below 300% of its borrowings,
         Northern Funds will reduce the borrowings of such Fund in accordance
         with the 1940 Act. In addition, as a matter of fundamental policy, the
         Funds may not enter into reverse repurchase agreements exceeding in the
         aggregate one-third of their respective total assets.

                  (11) Purchase the securities of any one issuer, other than
         obligations issued or guaranteed by the U.S. Government, its agencies
         or instrumentalities, if immediately after such purchase more than 5%
         of the value of such Fund's total assets would be invested in such
         issuer, except that: (a) up to 50% of the value of the California
         Municipal Money Market Fund's total assets (so long as no more than 25%
         of the value of its total assets are invested in the securities of any
         one issuer) and up to 25% of the value of the total assets of each of
         the other Funds may be invested in any securities without regard to
         this 5% limitation; and (b) with respect to each Fund, such 5%
         limitation shall not apply to repurchase agreements collateralized by
         obligations of the U.S. Government, its agencies or instrumentalities.
         (This restriction does not apply to the International Fixed Income Fund
         and Florida Intermediate Tax-Exempt Fund.)

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

         As a non-fundamental investment restriction, the International Fixed
Income and Florida Intermediate Tax-Exempt Funds 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 each Fund 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, its agencies and
instrumentalities).

         Except as otherwise provided in Investment Restriction (9), for the
purpose of such restriction in determining industry classification with respect
to the Funds other than the International Funds and the Technology Fund,
Northern Funds intends to use the industry classification titles in the Standard
Industrial Classification Manual. With respect to the International Funds,
Northern Funds intends to use the Morgan Stanley Capital International industry
classification titles. With respect to the Technology Fund, Northern Funds
intends to consider an issuer to be principally engaged in technology business
activities if such issuer is listed on the H&Q Index, the SoundView Technology
Index, the technology grouping of the S&P 500 Index or any other comparable
index. The freedom of action reserved in


                                      -46-
<PAGE>   139
Investment Restriction (9) above 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, and such freedom with respect to foreign
branches of U.S. banks is subject to the requirement that the domestic parent be
unconditionally liable in the event that a foreign branch fails to pay on its
instruments for any reason. Securities held in escrow or separate accounts in
connection with the Funds' 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.

         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 Fund, does not exceed 10% of the
value of the Fund's total assets.

         As stated in the Prospectus under "Additional Investment Information,
Risks and Considerations -- Investment Restrictions," the Money Market, U.S.
Government Money Market, U.S. Government Select Money Market, Municipal Money
Market and California Municipal Money Market Funds intend, as a non-fundamental
policy, to diversify their investments in accordance with current SEC
regulations, which are more restrictive than the Funds' fundamental investment
restrictions stated above. As further stated in the Prospectus, securities
subject to unconditional demand features acquired by the Money Market Funds must
satisfy special SEC diversification requirements. In particular, a security that
has an unconditional demand feature (as defined by SEC regulations) which is
issued by a person that, directly or indirectly, does not control, and is not
controlled by or under common control with, the issuer of the security (an
"Unconditional Demand Feature") is subject to the following diversification
requirements: Immediately after the acquisition of the security, a Money Market
Fund may not have invested more than 10% of its total assets in securities
issued by or subject to Unconditional Demand Features from the same person,
except that a Fund may invest up to 25% of its total assets in securities
subject to Unconditional Demand Features of persons that are rated in the
highest rating category as determined by two NRSROs (or one NRSRO if the
security is rated by only one NRSRO). In addition, as mentioned in the
Prospectus, the Municipal Money Market and California Municipal Money Market
Funds will limit their investments in certain conduit securities that are not
rated in the highest 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, to 5% of their total assets, with investments in any one
such issuer being limited to no more than 1% of a Fund'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


                                      -47-
<PAGE>   140
an Unconditional Demand Feature and involve an arrangement whereunder a person,
other than a governmental 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.

         In addition to the foregoing, each Money Market Fund 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 Fund has the right to sell the securities to third parties.

         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, the Fund.

         Although the foregoing Investment Restrictions would permit the Money
Market Funds to acquire options, enter into forward currency contracts and
engage in short sales and interest rate and currency swaps, they are not
currently permitted to engage in these transactions under SEC regulations. In
addition, the U.S. Government Select Money Market Fund does not intend to
purchase any bank or corporate obligation during the current fiscal year.

         In order to permit the sale of the Funds' shares in certain states,
Northern Funds may make commitments with respect to the Funds more restrictive
than the investment policies listed above and in the Prospectus. Should Northern
Funds determine that any commitment made to permit the sale of a Fund's shares
in any state is no longer in the best interests of the Fund, it will revoke the
commitment by terminating sales of a Fund's shares in the state involved.

INVESTMENT ADVISER, TRANSFER AGENT AND CUSTODIAN

         Northern Trust is a wholly-owned subsidiary of The Northern Trust
Corporation, a Chicago-based multi-bank holding company with subsidiaries in
Illinois, Florida, New York, Arizona, California and Texas. Northern Trust has
for more than 100 years managed the assets of individuals, charitable
organizations, foundations and large corporate investors. One of the nation's
leading providers of trust and investment management services, Northern Trust
first entered the mutual fund business in 1983 by offering money market funds to
institutional clients. As part of its investment advisory services, Northern
Trust offers extensive research services to its clients. As of the date of this
Additional Statement, nearly 300 financial institutions nationwide purchase
Northern Trust's economic advisory services. As of June 30, 1996, Northern Trust
Corporation had approximately $21.8 billion in assets and $13.3 billion in
deposits. Northern Trust and its affiliates administered in various capacities
(including as master trustee, investment manager or custodian) over $692.9
billion in assets as of June 30, 1996, including $120 billion for which Northern
Trust had management responsibility. Northern Trust is one of the strongest
banking organizations in the United States and its clients include public and
private retirement funds, endowments, 


                                      -51-
<PAGE>   144
foundations, trusts, corporations and individuals. Northern Funds complements
the banking and personal trust services available through Northern Trust by
allowing Northern Trust's banking and trust clients to consolidate the
management of their finances and thereby move one step closer to one-stop
financial shopping. Northern Funds utilizes a state-of-the-art investor services
center. Also, trained investment representatives are available at Northern
Trust's offices to assist investors in allocating their investments. Northern
Trust 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. Northern Trust manages the Funds through a team of professionals,
led by portfolio managers who follow a disciplined process to develop investment
strategies. The purpose of this approach is to promote consistent management.
The portfolio managers draw upon the resources of Northern Trust's research
department with specialists in economic analysis, investment strategy, credit
quality and tax law, and which supplies information on interest rates, GNP
growth, corporate profits and other factors.

         Subject to the general supervision of the Board of Trustees, Northern
Trust makes decisions with respect to and places orders for all purchases and
sales of portfolio securities for the Funds, and also provides certain ancillary
services. Northern Trust's Advisory Agreement with Northern Funds has been
approved by the Board of Trustees, including the "non-interested" Trustees, and
the initial shareholder of Northern Funds. The Advisory Agreement provides that
in executing portfolio transactions and in selecting brokers or dealers (a) with
respect to common and preferred stocks, Northern Trust shall use its best
judgment to obtain the best overall terms available, and (b) with respect to
other securities, Northern Trust shall attempt to obtain best net price and
execution. 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.

         For the fiscal years or periods indicated, the amount of commissions
paid by each Fund was as follows:

</TABLE>

(1)      The Select Equity and International Select Equity Funds commenced
         operations on April 6 and April 5, 1994, respectively.

         No commissions were paid by the Funds to any "affiliated" persons (as
defined in the 1940 Act) of the Funds. 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, Northern Trust 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.

         Northern Funds is required to identify any securities of its "regular
brokers or dealers" or their parents which Northern Funds acquired during its
most recent fiscal year.

         During the fiscal year ended March 31, 1996, the Growth Equity Fund did

         During the fiscal year ended March 31, 1996, the Florida Intermediate
Tax-Exempt Fund, Technology Fund and Stock Index Fund had not yet commenced
operations.

         During the fiscal year ending March 31, 1996, Northern Funds directed
brokerage transactions to brokers because of research services provided. The
amount of such transactions and related commissions were as follows: for the
Income Equity Fund, $20,307,086.10 in research commission transactions and
$29,633.56 in research commissions; for the Growth Equity Fund, $169,902,642.59
in research commission transactions and $232,359.36 in research commissions; for

Select Equity Fund, $93,051,336.94 in research commission transactions and
$493,910.30 in research commissions.

         The Funds 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 Funds will engage in this practice, however, only when Northern Trust
believes such practice to be in the Funds' interests.

         Northern Trust's investment advisory duties for Northern Funds are
carried out through its Trust Department. On occasions when Northern Trust deems
the purchase or sale of a security to be in the best interests of a Fund as well
as other fiduciary or agency accounts managed by it (including any other
portfolio, investment company or account for which Northern Trust acts as
adviser), the Agreement provides that Northern Trust, to the extent permitted by
applicable laws and regulations, may aggregate the securities to be sold or
purchased for such Fund with those to be sold or purchased for such other
accounts in order to obtain the best overall terms available with respect to
common and preferred stocks and the best net price and execution with respect to
other securities. In such event, allocation of the securities so purchased or

accounts involved. In some instances, this procedure may adversely affect the
size of the position obtainable for the Fund or the amount of the securities
that are able to be sold for the Fund. 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 Trust, at its discretion but subject
to applicable law, to select the executing broker or dealer on the basis of
Northern Trust's opinion of the reliability and quality of such broker or
dealer.

         The Advisory Agreement provides that Northern Trust may render similar
services to others so long as its services under such Agreement are not impaired
thereby. The Advisory Agreement also provides that Northern Funds will indemnify
Northern Trust 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.

         From time to time, Northern Trust may voluntarily waive a portion or
all of its fees otherwise payable to it with respect to the Funds.

         For the fiscal years or periods indicated, Northern Trust earned
advisory fees, after fee waivers, as follows:

average daily net assets to the extent they exceed $100 million, plus (b) a
basic accounting fee of (i) $25,000 annually for each Fund, plus (ii) 1/100th of
1% annually of each Fund's average daily net assets to the extent they exceed

plus (d) a fixed dollar fee for each time that Northern Trust as Custodian
receives or transmits funds via wire, plus (e) reimbursement of expenses
incurred by Northern Trust as Custodian for telephone, postage, courier fees,
office supplies and duplicating. The fees referred to in clauses (c) and (d) are
subject to annual upward adjustments based on increases in the Consumer Price
Index for All Urban Consumers, provided that Northern Trust may permanently or
temporarily waive all or any portion of any upward adjustment.

         As compensation for the services rendered to the International Funds
under the Foreign Custody Agreement, and the assumption by Northern Trust of
certain related expenses, Northern Trust is entitled to payment from each of
those Funds as follows: (i) $35,000 annually for each Fund, plus (ii) 9/100th of
1% annually of each Fund's average daily net assets, plus (iii) reimbursement
for fees incurred by Northern Trust as foreign Custodian for telephone, postage,
courier fees, office supplies and duplicating. As compensation for basic
accounting services rendered to the International Funds by Northern Trust,
Northern Trust is entitled to receive $25,000 for the first $50 million of each
of those Fund's average daily net assets and 1/100th of 1% of each Fund's
average daily net assets in excess of $50 million.

(1)      The Money Market, U.S. Government Money Market and Municipal Money
         Market Funds commenced operations on April 11, 1994; the U.S.
         Government Select and California Municipal Money Market Funds commenced
         operations on December 12, and December 29, 1994, respectively; and the
         Select Equity and International Select Equity Funds commenced
         operations on April 6, and April 5, 1994, respectively.

         Unless sooner terminated, each of the Advisory Agreement, Transfer
Agency Agreement, Custodian Agreement and Foreign Custody Agreement between
Northern Trust and Northern Funds will continue in effect with respect to a
particular Fund until March 31, 1997, and thereafter for successive 12-month
periods, provided that the 

                                      -61-
<PAGE>   154
continuance is approved at least annually (a) 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 (b) by the
Trustees or by the vote of a majority of the outstanding shares of the Fund (as
defined under "Organization" in the Prospectus). Each agreement is terminable at
any time without penalty by Northern Funds (by specified Trustee or shareholder
action) on 60 days' written notice to Northern Trust and by Northern Trust on 60
days' written notice to Northern Funds.

         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 Trust believes that it may perform the services
contemplated by its agreements with Northern Funds 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 Trust from continuing to perform such services for Northern Funds.

         Should future legislative, judicial or administrative action prohibit
or restrict the activities of Northern Trust in connection with the provision of
services on behalf of Northern Funds, Northern Funds might be required to alter
materially or discontinue its arrangements with Northern Trust and change its
method of operations. It is not anticipated, however, that any change in
Northern Funds' method of operations would affect the net asset value per share
of any Fund 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, Northern Funds expects that Northern Trust would consider the
possibility of offering to perform some or all of the services now provided by
Sunstone. It is not possible, of course, to predict whether or in what form such
restrictions might be relaxed or the terms upon which Northern Trust might offer
to provide services for consideration by the Trustees.

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

ADMINISTRATOR AND DISTRIBUTOR

         Under its Administration Agreement, Sunstone has agreed, subject to the
direction and control of Northern Funds' Board of Trustees and utilizing
information provided by Northern Funds and its agents, to (1) provide office
space, facilities, equipment and personnel to carry out its services; (2)
compile data for and prepare with respect to the Funds timely Notices to the
Securities and Exchange Commission ("SEC") required pursuant to Rule 24f-2 under
the 1940 Act and Semi-Annual Reports on Form N-SAR; (3) prepare for execution by
Northern Funds and file all federal income and excise tax returns and state
income tax returns (and such other required tax filings as may be agreed to by
the parties) other than those required to be made by Northern Funds' custodian
and transfer agent; (4) prepare compliance filings relating to the registration
of the securities of the Funds pursuant to state securities laws with the advice
of Northern Funds' counsel; (5) assist the Fund accountants with preparing the
Annual and Semi-Annual Reports required pursuant to Section 30(d) under the 1940
Act; (6) assist to the extent requested by Northern Funds with the preparation
of the Registration Statement for the Funds (on Form N-1A or any replacement
therefor) and any amendments thereto, and proxy materials; (7) prepare and
monitor each Fund's expense accruals and cause all appropriate expenses to be
paid from Fund assets on proper authorization from the Fund; (8) assist in the
acquisition of the Funds' fidelity bond required by the 1940 Act, monitor the
amount of the bond and make the necessary SEC filings related thereto; (9) from
time to time as Northern Funds may reasonably request or as Sunstone deems
appropriate, check each Fund's compliance with the policies and limitations
relating to portfolio investments as set forth in the Prospectus, Additional
Statement and Declaration of Trust and monitor each Fund's status as a regulated
investment company under Subchapter M of the Internal Revenue Code, as amended
(but this function shall not relieve the Fund's investment adviser of its
day-to-day responsibility for such compliance); (10) maintain, and/or coordinate
with the other service providers the maintenance of, the accounts, books and
other documents required pursuant to Rule 31a-1(a) and (b) under the 1940 Act;
and (11) generally assist in each Fund's administrative operations. In addition,
Sunstone has agreed to monitor Northern Funds' arrangements with respect to
services provided by Service Organizations. Under the Administration Agreement,
Sunstone is not liable for any error of judgment or mistake of law or for any
loss suffered by the Funds in connection with the performance of the
Administration Agreement, except a loss resulting from willful


                                      -63-
<PAGE>   156
misfeasance, bad faith or gross negligence on the part of Sunstone in the
performance of its duties or from its reckless disregard of its duties and
obligations under the Agreement.

         Unless sooner terminated the Administration Agreement will continue in
effect with respect to a particular Fund until March 31, 1997, and thereafter
for successive 12-month periods, provided that the agreement is approved
annually (a) 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 (b) by the Trustees or by the vote of a majority of
the outstanding shares of such Fund (as defined under "Description of Shares").
Notwithstanding the foregoing, the Administration Agreement shall continue
automatically for an indefinite period unless the Board of Trustees shall have
provided Sunstone with at least 90 days' written notice of its determination not
to renew the Agreement.

         For its administrative services, Sunstone is entitled to an
administration fee, computed daily and payable monthly, at the annual rate of
0.15% of the Funds' average aggregate daily net assets. For the fiscal years or
periods indicated, Sunstone earned, after waivers, administrative fees as
follows:

(1)      The Money Market, U.S. Government Money Market and Municipal Money
         Market Funds commenced operations on April 11, 1994; the U.S.
         Government Select and California Municipal Money Market Funds commenced
         operations on December 12, and December 29, 1994, respectively; and the
         Select Equity and International Select Equity Funds commenced
         operations on April 6, and April 5, 1994, respectively.

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

         The Administration Agreement and the Distribution Agreement provide
that Sunstone may render similar services to others so long as its services
under the Agreements are not impaired thereby. The Administration and
Distribution Agreements provide that Northern Funds will indemnify Sunstone
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 such Agreements) under certain
circumstances.

SERVICE ORGANIZATIONS

         As stated in the Funds' Prospectus, the Funds may enter into agreements
from time to time with Service Organizations providing for support and/or
distribution services to customers of the Service Organizations who are the
beneficial owners of Fund shares. Under the agreements, the Funds may pay
Service Organizations up to .25% (on an annualized basis) of the average daily
net asset value 


                                      -66-
<PAGE>   159
of the shares beneficially owned by their customers. Support services provided
by Service Organizations under their agreements may include: (a) processing
dividend and distribution payments from a Fund; (b) providing information
periodically to customers showing their share positions; (c) arranging for bank
wires; (d) responding to customer inquiries; (e) providing subaccounting with
respect to shares beneficially owned by customers or the information necessary
for subaccounting; (f) forwarding shareholder communications; (g) assisting in
processing share purchase, exchange and redemption requests from customers; (h)
assisting customers in changing dividend options, account designations and
addresses; and (i) other similar services requested by the Funds. In addition,
Service Organizations may provide assistance (such as the forwarding of sales
literature and advertising to their customers) in connection with the
distribution of Fund shares.

         The Funds' arrangements with Service Organizations under the agreements
are governed by two Plans (a Service Plan and a Distribution and Service Plan),
which have been adopted by the Board of Trustees and (in the case of the
Distribution and Service Plan) by the initial shareholder of Northern Funds.
Because the Distribution and Service Plan contemplates the provision of services
related to the distribution of Fund shares (in addition to support services),
that Plan has been adopted in accordance with Rule 12b-1 under the 1940 Act. In
accordance with the Plans, the Board of Trustees reviews, at least quarterly, a
written report of the amounts expended in connection with the Funds'
arrangements with Service Organizations and the purposes for which the
expenditures were made. In addition, the Funds' arrangements with Service
Organizations must be approved annually by a majority of the Trustees, including
a majority of the Trustees who are not "interested persons" of the Funds as
defined in the 1940 Act and have no direct or indirect financial interest in
such arrangements (the "Disinterested Trustees").

         The Board of Trustees believes that there is a reasonable likelihood
that their arrangements with Service Organizations will benefit each Fund and
its shareholders. Any material amendment to the arrangements with Service
Organizations under the agreements must be approved by a majority of the Board
of Trustees (including a majority of the Disinterested Trustees), and any
amendment to increase materially the costs under the Distribution and Service
Plan with respect to a Fund must be approved by the holders of a majority of the
outstanding shares of the Fund involved. So long as the Distribution and Service
Plan is in effect, the selection and nomination of the members of the Board of
Trustees who are not "interested persons" (as defined in the 1940 Act) of the
Northern Funds will be committed to the discretion of such disinterested
Trustees.

         For the fiscal period ended March 31, 1996, none of the Funds paid fees
with respect to either of the Plans.

COUNSEL AND AUDITORS

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

         Arthur Andersen LLP, independent accountants, 33 West Monroe Street,
Chicago, Illinois 60603-5385 serve as auditors for Northern Funds. The financial
statements dated March 31, 1996, incorporated by reference into this Additional
Statement have been incorporated in reliance on the report of Arthur Andersen
LLP given on the authority of said firm as experts in auditing and accounting.

IN-KIND PURCHASES

         Payment for shares of a Fund may, in the discretion of Northern Trust,
be made in the form of securities that are permissible investments for the Fund
as described in the Prospectus. For further information about this form of
payment, contact the Transfer Agent. In connection with an in-kind securities
payment, a Fund will require, among other things, that the securities be valued
on the day of purchase in accordance with the pricing methods used by the Fund
and that the Fund 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 Fund; and that adequate information be provided
concerning the basis and other tax matters relating to the securities. In
addition, so long as shares in a Fund are offered or sold in Texas, any
securities that are accepted as payment for the shares of the Fund will be
limited to securities that are issued in transactions that involve a bona fide
reorganization or statutory merger, or will be limited to other acquisitions of
portfolio securities (except for municipal debt securities issued by state
political subdivisions or their agencies or instrumentalities) that: (a) meet
the investment objective and policies of the Portfolio; (b) are acquired for
investment and not for resale; (c) are liquid securities that are not restricted
as to transfer either by law or liquidity of market; and (d) have a value that
is readily ascertainable (and not established only by evaluation procedures) as
evidenced by a listing on the American Stock Exchange, New York Stock Exchange
or Nasdaq or as evidenced by their status as U.S. Government Securities, bank
certificates of deposit, banker's acceptances, corporate and other debt
securities that are actively traded, money market securities and other like
securities with a readily ascertainable value.

AUTOMATIC INVESTING PLAN

         The Automatic Investing Plan permits an investor to use "Dollar Cost
Averaging" in making investments. Instead of trying to time market performance,
a fixed dollar amount is invested in shares at predetermined intervals. This may
help investors reduce


                                      -68-
<PAGE>   161
their average cost per share because the agreed upon fixed investment amount
allows more shares to be purchased during periods of lower share prices and
fewer shares during periods of higher share prices. In order to be effective,
Dollar Cost Averaging should usually be followed on a sustained, consistent
basis. Investors should be aware, however, that shares bought using Dollar Cost
Averaging are purchased without regard to their price on the day of investment
or to market trends. Dollar Cost Averaging does not assure a profit and does not
protect against losses in a declining market. In addition, while investors may
find Dollar Cost Averaging to be beneficial, it will not prevent a loss if an
investor ultimately redeems his shares at a price which is lower than their
purchase price. An investor may want to consider his financial ability to
continue purchases through periods of low price levels.

REDEMPTIONS AND EXCHANGES

         Exchange requests received on a Business Day prior to the time shares
of the Funds involved in the request are priced will be processed on the date of
receipt. "Processing" a request means that shares in the Fund from which the
shareholder is withdrawing an investment will be redeemed at the net asset value
per share next determined on the date of receipt. Shares of the new Fund into
which the shareholder is investing will also normally be purchased at the net
asset value per share next determined coincident to or after the time of
redemption. Exchange requests received on a Business Day after the time shares
of the Funds involved in the request are priced will be processed on the next
Business Day in the manner described above.

         Northern Funds reserves the right to make payment for redemptions in
readily marketable securities. If this occurred, a shareholder would bear any
brokerage or other transaction costs incurred in converting the securities so
received to cash. Northern Funds also reserves the right to require a
shareholder to redeem involuntarily shares in a Fund if the balance held of
record by the shareholder drops below $750 and the shareholder does not increase
such balance to $1,000 or more upon 30 days' notice. Northern Funds will not
require a shareholder to redeem shares of a Fund if the balance held of record
by the shareholder is less than $750 solely because of a decline in the net
asset value of the Fund's shares or because the shareholder has made an initial
investment in a lower amount in accordance with the Automatic Investment Plan.
Northern Funds may also redeem shares involuntarily if the redemption is
appropriate to carry out Northern Funds' responsibilities under the 1940 Act
(see, e.g., "Amortized Cost Valuation").

         Northern Funds may redeem shares involuntarily to reimburse a Fund for
any loss sustained by reason of the failure of a shareholder to make full
payment for shares purchased by the shareholder or to collect any charge
relating to a transaction


                                      -69-
<PAGE>   162
effected for the benefit of a shareholder which is applicable to Fund shares as
provided in the Funds' Prospectus from time to time.

                             PERFORMANCE INFORMATION

MONEY MARKET FUNDS

         From time to time Northern Funds may advertise quotations of "yields"
and "effective yields" with respect to each Money Market Fund, and
"tax-equivalent yields" with respect to shares of the Municipal Money Market
Fund and the California Municipal Money Market Fund, computed in accordance with
a standardized method based upon the seven-day period ended on the date of
calculation. In arriving at quotations as to "yield," Northern Funds 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. Based on the
foregoing calculations, for the period ended March 31, 1996, the 7-day yields
for the Money Market Funds, after fee waivers, were as follows: Money Market
Fund, 4.90%; U.S. Government Money Market Fund, 4.78%; Municipal Money Market
Fund, 3.05%; U.S. Government Select Money Market Fund, 4.91%; and California
Municipal Money Market Fund, 3.08%. For the period ended March 31, 1996, the
7-day yields for the Money Market Funds, absent fee waivers, were as follows:
Money Market Fund, 4.73%; U.S. Government Money Market Fund, 4.50%; Municipal
Money Market Fund, 2.86%; U.S. Government Select Money Market Fund, 4.71%; and
California Municipal Money Market Fund, 2.98%.

         The "effective yield" with respect to the shares of a Money Market Fund
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.
Based on the foregoing calculations, for the period ended March 31, 1996, the 
7-day effective yields for the Money Market Funds, after fee waivers, were as
follows: Money Market Fund, 5.02%; U.S. Government Money Market Fund, 4.90%;
Municipal Money Market Fund, 3.09%; U.S. Government Select Money Market Fund,
5.03%; and California Municipal Money Market Fund, 3.13%.

         "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. For the
period ended March 31, 1996, and using a federal income tax rate of 31%, the
7-day tax-equivalent yields, after fee waivers, were 4.42% and 4.46% for the


                                      -70-
<PAGE>   163
Municipal Money Market and California Municipal Money Market Funds,
respectively.

NON-MONEY MARKET FUNDS

         A Non-Money Market Fund calculates its "average annual total 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:


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

         Where:            T =              average annual total return;

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

                           P =              hypothetical initial payment of 
                                            $1,000; and

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

         Based on the foregoing calculations, the average annual total returns
for the Non-Money Market Funds for the fiscal year ended March 31, 1996 and for
the period from the respective dates they commenced operations to March 31,
1996, were as follows: U.S. Government Fund, 7.65% and 5.54%; Fixed Income Fund,
11.18% and 7.60%; Intermediate Tax-Exempt Fund, 6.81% and 5.58%; Tax-Exempt
Fund, 7.80% and 6.78%; International Fixed Income Fund, 5.84% and 9.23%; Income
Equity Fund, 20.41% and 10.92%; Growth Equity Fund, 25.13% and 15.63%; Select
Equity Fund, 25.70% and 16.71%; Small Cap Fund, 24.09% and 11.69%; International
Growth Equity Fund, 8.61% and 2.82%; and International Select Equity Fund,
10.20% and 3.96%. The Florida Intermediate Tax-Exempt Fund, Technology Fund and
Stock Index Fund had not commenced operations during the fiscal year ended March
31, 1996. During these periods, Northern Trust and Sunstone waived a portion of
their fees.

         A Non-Money Market Fund calculates its "aggregate total 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:


                                      -71-
<PAGE>   164
                                                       ERV
                  Aggregate Total Return =          [(-----) - 1]
                                                        P

   
         The calculations are made assuming that (a) all dividends and capital
gain distributions are reinvested on the reinvestment dates at the price per
share existing on the reinvestment date, and (b) 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. Based on the foregoing calculations, the aggregate
total return for the Non-Money Market Funds for the periods from the respective
dates they commenced operations to March 31, 1996, were as follows: U.S.
Government Fund, 11.41%; Fixed Income Fund, 15.81%; Intermediate Tax-Exempt
Fund, 11.48%; Tax-Exempt Fund, 14.04%; International Fixed Income Fund, 19.41%;
Income Equity Fund, 23.07%; Growth Equity Fund, 33.93%; Select Equity Fund,
35.98%; Small Cap Fund, 24.79%; International Growth Equity Fund, 5.73%; and
International Select Equity Fund, 8.04%. Based on the foregoing calculations,
the aggregate total return for the Technology Fund for the period April 1, 1996
(commencement of operations) to September 30, 1996 was 22.88%. The Florida
Intermediate Tax-Exempt Fund and Stock Index Fund had not commenced operations
during these periods. During these periods, Northern Trust and Sunstone waived a
portion of their fees.
    

         A Non-Money Market Fund calculates its 30-day (or one month) standard
yield in accordance with the method prescribed by the SEC for mutual funds:

                                     a - b   6
                                     -----
                           Yield = 2[(cd + 1)   - 1]

Where:                     a =      dividends and interest earned 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.

         Based on the foregoing calculations, for the 30-day period ended March
31, 1996, the yields for the U.S Government, Fixed Income, Intermediate
Tax-Exempt, Tax-Exempt and International Fixed Income Funds, after fee waivers,
were 5.11%, 5.56%, 3.67%, 4.39%


                                      -72-
<PAGE>   165
   
and 5.49%, respectively. Also for the 30-day period ended March 31, 1996, the
yields for the U.S Government, Fixed Income, Intermediate Tax-Exempt, Tax-Exempt
and International Fixed Income Funds, absent fee waivers, were 4.91%, 5.31%,
3.50%, 4.19% and 4.59%, respectively.
    

         A Non-Money Market Fund's "tax-equivalent" yield is computed by: (a)
dividing the portion of the Fund's yield (calculated as above) that is exempt
from federal income tax by one minus a stated federal income tax rate; and (b)
adding the quotient to that portion, if any, of the Fund's yield that is not
exempt from federal income tax. For the period ended March 31, 1996, and using a
federal income tax rate of 31%, the 30-day tax-equivalent yields, after fee
waivers, were 5.32% and 6.36% for the Intermediate Tax-Exempt and Tax-Exempt
Funds, respectively.

GENERAL INFORMATION

         Any fees imposed by Northern Trust or other Service Organizations on
their customers in connection with investments in the Funds are not reflected in
Northern Funds' calculations of performance for the Funds.

         Each Fund's performance will fluctuate, unlike bank deposits or other
investments which pay a fixed yield for a stated period of time. Past
performance is not necessarily indicative of future return. Actual performance
will depend on such variables as portfolio quality, average portfolio maturity,
the type of portfolio instruments acquired, changes in interest rates, portfolio
expenses and other factors. Performance is one basis investors may use to
analyze a Fund as compared to other funds and other investment vehicles.
However, performance of other 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 performance.

         From time to time, a Fund's performance may also be compared to other
mutual funds tracked by financial or business publications and periodicals. For
example, a Fund may quote Morningstar, Inc. in its advertising materials.
Morningstar, Inc. is a mutual fund rating service that rates mutual funds on the
basis of risk-adjusted performance. Rankings that compare the performance of the
Funds to one another in appropriate categories over specific periods of time may
also be quoted in advertising.

         Ibbotson Associates of Chicago, Illinois ("Ibbotson") provides
historical returns of the capital markets in the United States, including common
stocks, small capitalization stocks, long-term corporate bonds,
intermediate-term government bonds, long-term government bonds, Treasury bills,
the U.S. rate of inflation (based on the Consumer Price Index), and combinations
of various capital


                                      -73-

markets. The performance of these capital markets is based on the returns of
different indices. The Funds may use the performance of these capital markets in
order to demonstrate general risk-versus-reward investment scenarios.
Performance comparisons may also include the value of a hypothetical investment
in any of these capital markets. The risks associated with the security types in
any capital market may or may not correspond directly to those of the Funds. The
Funds may also compare performance to that of other compilations or indices that
may be developed and made available in the future.

         The Funds may also from time to time include discussions or
illustrations of the effects of compounding in advertisements. "Compounding"
refers to the fact that, if dividends or other distributions on a Fund
investment are reinvested by being paid in additional Fund shares, any future
income or capital appreciation of a Fund would increase the value, not only of
the original investment in the Fund, but also of the additional Fund shares
received through reinvestment.

         The Funds may include discussions or illustrations of the potential
investment goals of a prospective investor (including materials that describe
general principles of investing, such as asset allocation, diversification, risk
tolerance, and goal setting, questionnaires designed to help create a personal
financial profile, worksheets used to project savings needs based on assumed
rates of inflation and hypothetical rates of return and action plans offering
investment alternatives), investment management techniques, policies or
investment suitability of a Fund (such as value investing, market timing, dollar
cost averaging, asset allocation, constant ratio transfer, automatic account
rebalancing, the advantages and disadvantages of investing in tax-deferred and
taxable investments), economic and political conditions, the relationship
between sectors of the economy and the economy as a whole, the effects of
inflation and historical performance of various asset classes, including but not
limited to, stocks, bonds and Treasury bills. From time to time advertisements,
sales literature, communications to shareholders or other materials may
summarize the substance of information contained in shareholder reports
(including the investment composition of a Fund), as well as the views of
Northern Trust as to current market, economic, trade and interest rate trends,
legislative, regulatory and monetary developments, investment strategies and
related matters believed to be of relevance to a Fund. In addition, selected
indices may be used to illustrate historic performance of selected asset
classes. The Funds may also include in advertisements, sales literature,
communications to shareholders or other materials, charts, graphs or drawings
which illustrate the potential risks and rewards of investment in various
investment vehicles, including but not limited to, stocks, bonds, treasury bills
and shares of a Fund. In addition, advertisements, sales literature,
communications to shareholders or other materials


                                      -74-
<PAGE>   167
may include a discussion of certain attributes or benefits to be derived by an
investment in a Fund and/or other mutual funds, shareholder profiles and
hypothetical investor scenarios, timely information on financial management, tax
and retirement planning and investment alternative to certificates of deposit
and other financial instruments. Such sales literature, communications to
shareholders or other materials may include symbols, headlines or other material
which highlight or summarize the information discussed in more detail therein.

         Materials may include lists of representative clients of Northern
Trust. Materials may refer to the CUSIP numbers of the Funds and may illustrate
how to find the listings of the Funds in newspapers and periodicals. Materials
may also include discussions of other Funds, products, and services.

         The Funds may quote various measures of volatility and benchmark
correlation in advertising. In addition, the Funds may compare these measures to
those of other funds. Measures of volatility seek to compare the historical
share price fluctuations or total returns to those of a benchmark. Measures of
benchmark correlation indicate how valid a comparative benchmark may be.
Measures of volatility and correlation may be calculated using averages of
historical data.

         The Fund may advertise examples of the effects of periodic investment
plans, including the principle of dollar cost averaging. In such a program, an
investor invests a fixed dollar amount in a Fund at periodic intervals, thereby
purchasing fewer shares when prices are high and more shares when prices are
low. While such a strategy does not assure a profit or guard against loss in a
declining market, the investor's average cost per share can be lower than if
fixed numbers of shares are purchased at the same intervals. In evaluating such
a plan, investors should consider their ability to continue purchasing shares
during periods of low price levels.

         A Fund may advertise its current interest rate sensitivity, duration,
weighted average maturity or similar maturity characteristics.

         Advertisements and sales materials relating to a Fund may include
information regarding the background and experience of its portfolio managers.



                            AMORTIZED COST VALUATION

         As stated in the Prospectus, each Money Market Fund 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


                                      -75-
<PAGE>   168
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 Fund would
receive if the Fund sold the instrument. During such periods the yield to
investors in the Fund 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 Fund value on a particular day, a prospective investor in the
Fund 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, Northern Funds 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, Northern Funds' Board of Trustees, in supervising the
Funds' operations and delegating special responsibilities involving portfolio
management to Northern Trust, has established procedures that are intended,
taking into account current market conditions and the Funds' investment
objectives, to stabilize the net asset value of each Money Market Fund, 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 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 exceeds 1/2 of 1%, the Trustees' procedures
provide that 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 Fund, 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


                                      -76-
<PAGE>   169
proportionately contribute to the Fund'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 Fund.

         Rule 2a-7 requires that each Money Market Fund limit its investments to
instruments which Northern Trust determines 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 Money Market Fund 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 397 days. Should the disposition of a portfolio security
result in a dollar-weighted average portfolio maturity of more than 90 days, the
Rule requires a Money Market Fund to invest its available cash in such a manner
as to reduce such maturity to the prescribed limit as soon as reasonably
practicable.

                                      TAXES

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

         The discussions of federal and state tax consequences in the Prospectus
and this Additional Statement are based on the Code and the laws and regulations
issued thereunder as in effect on the date of this Additional Statement. Future
legislative or administrative changes or court decisions may significantly
change the conclusions expressed herein, and any such changes or decisions may
have a retroactive effect with respect to the transactions contemplated herein.

FEDERAL - GENERAL INFORMATION

         Each Fund intends to qualify 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 Fund is
generally 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 the sum of 90% of its tax-exempt income
and 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


                                      -77-
<PAGE>   170
"Distribution Requirement") and satisfies certain other requirements of the Code
that are described below.

         In addition to satisfaction of the Distribution Requirement, each Fund
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") and derive less than
30% of its gross income from the sale or other disposition of securities and
certain other investments held for less than three months (the "Short-Short
Test"). Interest (including original issue discount and accrued market discount)
received by a Fund at maturity or on disposition of a security held for less
than three months will not be treated as other income which is attributable to
realized market appreciation, but will be treated as gross income from the sale
or other disposition of securities for this purpose.

         In addition to the foregoing requirements, at the close of each quarter
of its taxable year, at least 50% of the value of each Fund'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 a
Fund has not invested more than 5% of the value of its total assets in
securities of such issuer and as to which a Fund does not hold more than 10% of
the outstanding voting securities of such issuer) and no more than 25% of the
value of each Fund'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 Fund controls and
which are engaged in the same or similar trades or businesses.

         Each Fund 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, regardless of the length of
time the shareholder has held the shares, whether such gain was recognized by
the Fund prior to the date on which a shareholder acquired shares of the Fund
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 any capital gain dividends that have
been paid with respect to such shares.

         In the case of corporate shareholders, distributions of a Fund for any
taxable year generally qualify for the dividends received deduction to the
extent of the gross amount of "qualifying dividends" from domestic corporations
received by the Fund for the


                                      -78-
<PAGE>   171
year. A dividend usually will be treated as a "qualifying dividend" if it has
been received from a domestic corporation. A portion of the dividends paid by
the Income Equity Fund, Growth Equity Fund, Select Equity Fund and Small Cap
Fund may constitute "qualifying dividends." The other Funds, however, are not
expected to pay qualifying dividends.

         Ordinary income of individuals is taxable at a maximum nominal 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. An individual's long-term capital gains are
currently taxable at a maximum nominal rate of 28%. For corporations, long-term
capital gains and ordinary income are both taxable at a maximum nominal rate of
35% (an effective marginal rate of 39% applies in the case of corporations with
taxable incomes between $100,000 and $335,000, and an effective marginal rate of
38% applies in the case of corporations with taxable incomes between $15 million
and $18,333,333).

         If for any taxable year any Fund 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 taxable as ordinary income to the extent of such Fund's current and
accumulated earnings and profits and would be eligible for the dividends
received deduction in the case of corporate shareholders.

         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 Fund 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.

         Although each Fund 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 Fund
may be subject to the tax laws of such states or localities.

FEDERAL - TAX-EXEMPT INFORMATION

         As described in the Prospectus, the Municipal Money Market, California
Municipal Money Market, Intermediate Tax-Exempt, Tax- Exempt and Florida
Intermediate Tax-Exempt Funds are designed to provide investors with tax-exempt
interest income. The Funds are


                                      -79-
<PAGE>   172
not intended to constitute a balanced investment program and are not designed
for investors seeking capital appreciation or maximum tax-exempt income
irrespective of fluctuations in principal. Shares of the Funds 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 Funds' dividends
being tax-exempt. In addition, the Funds 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, 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, a partnership and its partners and an S
corporation and its shareholders.

         In order for the Municipal Money Market, California Municipal Money
Market, Intermediate Tax-Exempt, Tax-Exempt or Florida Intermediate Tax-Exempt
Funds 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
Fund must consist of tax-exempt obligations. An exempt-interest dividend is any
dividend or part thereof (other than a capital gain dividend) paid by a Fund and
designated as an exempt-interest dividend in a written notice mailed to
shareholders not later than 60 days after the close of the Fund's taxable year.
However, the aggregate amount of dividends so designated by a Fund cannot exceed
the excess of the amount of interest exempt from tax under Section 103 of the
Code received by the Fund 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 a Fund with respect to any taxable year which qualifies as
federal exempt-interest dividends will be the same for all shareholders
receiving dividends from the Fund with respect to such year.

         Interest on indebtedness incurred by a shareholder to purchase or carry
Fund shares generally is not deductible for federal income tax purposes. If a
shareholder holds Fund shares for six months or less, any loss on the sale or
exchange of those shares will be disallowed to the extent of the amount of
exempt-interest dividends earned with respect to the shares. The Treasury
Department, however, is authorized to issue regulations reducing the six-month
holding requirement to a period of not less than the greater of 31 days or the
period between regular distributions for investment


                                      -80-
<PAGE>   173
companies that regularly distribute at least 90% of its net tax-exempt interest.
No such regulations had been issued as of the date of this Additional Statement.

         Shareholders will be advised annually as to the federal income tax
consequences of distributions made by the Funds.


TAXATION OF CERTAIN FINANCIAL INSTRUMENTS

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

         Generally, futures contracts, options on futures contracts and certain
foreign currency contracts held by a Fund (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 is treated as short-term capital gain or loss and
60% of such gain or loss is treated as long-term capital gain or loss without
regard to the period the Fund holds the Instruments ("the 40-60 rule"). The
amount of any capital gain or loss actually realized by the Fund in a subsequent
sale or other disposition of those Instruments is adjusted to reflect any
capital gain or loss taken into account by the Fund in a prior year as a result
of the constructive sale of the Instruments. Losses with respect to Instruments
that are regarded as parts of a "mixed straddle" because their values fluctuate
inversely to the values of specific securities held by the Fund 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. Under short sales rules, which are also
applicable, the holding period of the securities forming part of the straddle
will (if they have not been held for the long-term holding period) be deemed not
to begin prior to termination of the straddle. With respect to certain
Instruments, deductions for interest and carrying charges may not be allowed.
Notwithstanding the rules described above, with respect to Instruments that are
part of a "mixed straddle" and are properly identified as such, a Fund may make
an election which will exempt (in whole or in part) those identified Instruments
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 the Fund's taxable year, but gains and
losses will be subject to such short


                                      -81-
<PAGE>   174
sales, wash sales and loss deferral rules and the requirement to capitalize
interest and carrying charges. Under Temporary Regulations, a Fund would be
allowed (in lieu of the foregoing) to elect either (a) 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 (b) 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. Options on futures contracts generally receive federal tax treatment
similar to that described above.

         With respect to futures contracts and other financial instruments
subject to the mark-to-market rules, the Internal Revenue Service has ruled in
private letter rulings that a gain realized from such a futures contact or
financial instrument will be treated as being derived from a security held for
three months or more (regardless of the actual period for which the contract or
instrument is held) if the gain arises as a result of a constructive sale under
the mark-to-market rules, and will be treated as being derived from a security
held for less than three months only if the contract or instrument is terminated
(or transferred) during the taxable year (other than by reason of
mark-to-market) and less than three months have elapsed between the date the
contract or instrument is acquired and the termination date. In determining
whether the Short-Short Test is met for a taxable year, increases and decreases
in the value of the Fund's futures contacts and other investments that qualify
as part of a "designated hedge," as defined in the Code, may be netted.

         A foreign currency contract must meet the following conditions in order
to be subject to the marking-to-market rules described above: (1) the contract
must require delivery of a foreign currency of a type in which regulated futures
contracts are traded or upon which the settlement value of the contract depends;
(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 Fund
may result in the creation of one or more straddles for federal income tax
purposes, in which case certain loss deferral, short sales, 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 certain Funds
may make, such as foreign debt securities and foreign


                                      -82-
<PAGE>   175
currency contracts, may be subject to the provisions of Subpart J 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
marking-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 marking-to-market or loss
deferral rules under the Code. Gain or loss attributable to the foreign currency
component of transactions engaged in by the Fund 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.

         Certain of the Funds may be subject to U.S. federal income tax on a
portion of any "excess distribution" from or a gain from the disposition of
shares of a passive foreign investment company.

SPECIAL STATE TAX CONSIDERATIONS PERTAINING TO THE CALIFORNIA
MUNICIPAL MONEY MARKET FUND

         Assuming the California Municipal Money Market Fund qualifies as a
regulated investment company, it will be relieved of liability for California
state franchise and corporate income tax to the extent its earnings are
distributed to its shareholders. The Fund may be taxed on its undistributed
taxable income. If for any year the California Municipal Money Market Fund does
not qualify as a regulated investment company, all of the Fund's taxable income


                                      -83-
<PAGE>   176
(including interest income on California Municipal Instruments for franchise tax
purposes only) may be subject to California state franchise or income tax at
regular corporate rates.

         If, at the close of each quarter of its taxable year, at least 50% of
the value of the total assets of a regulated investment company, or series
thereof, consists of (i) obligations the interest on which is exempt from
taxation under the California Constitution or any California statute
("California Municipal Instruments") and (ii) obligations of the United States
the interest on which is exempt from state income taxation under the United
States Constitution or the laws of the United States ("Federal Obligations"),
then a regulated investment company, or series thereof, will be qualified to pay
dividends exempt from California state personal income tax to its non-corporate
shareholders (hereinafter referred to as "California exempt-interest
dividends"). "Series" of a regulated investment company is defined as a
segregated portfolio of assets, the beneficial interest in which is owned by the
holders of an exclusive class or series of stock of the company. The California
Municipal Money Market Fund intends to qualify under the above requirements so
that it can pay California exempt-interest dividends. If the California
Municipal Money Market Fund fails to so qualify, no part of its dividends to
shareholders will be exempt from the California state personal income tax. The
California Municipal Money Market Fund may reject purchase orders for shares if
it appears desirable to avoid failing to so qualify.

         Within 60 days after the close of its taxable year, the California
Municipal Money Market Fund will notify each shareholder of the portion of the
dividends paid by the Fund to the shareholder with respect to such taxable year
which is exempt from California state personal income tax. The total amount of
California exempt-interest dividends paid by the Fund with respect to any
taxable year cannot exceed the excess of the amount of interest received by the
Fund for such year on California Municipal Instruments and Federal Obligations
over any amounts that, if the Fund were treated as an individual, would be
considered expenses related to tax-exempt income or amortizable bond premium and
would thus not be deductible under federal income or California state personal
income tax law. The percentage of total dividends paid by the Fund with respect
to any taxable year which qualifies as California exempt-interest dividends will
be the same for all shareholders receiving dividends from the Fund with respect
to such year.

         In cases where shareholders are "substantial users" or "related
persons" with respect to California Municipal Instruments held by the California
Municipal Money Market Fund, such shareholders should consult their tax advisers
to determine whether California exempt-interest dividends paid by the Fund with
respect to such obligations retain California state personal income tax
exclusion. In this connection, rules similar to those regarding


                                      -84-
<PAGE>   177
the possible unavailability of federal exempt-interest dividend treatment to
"substantial users" are applicable for California state tax purposes. See
"Federal - Tax-Exempt Information" above.

         To the extent any dividends paid to shareholders are derived from the
excess of net long-term capital gains over net short-term capital losses, such
dividends will not constitute California exempt-interest dividends and will
generally be taxed as long-term capital gains under rules similar to those
regarding the treatment of capital gain dividends for federal income tax
purposes. See "Federal - General Information" above. Moreover, interest on
indebtedness incurred by a shareholder to purchase or carry California Municipal
Money Market Fund shares is not deductible for California state personal income
tax purposes if the Fund distributes California exempt-interest dividends during
the taxable year.

         California may tax income derived from repurchase agreements involving
federal obligations because such income represents a premium paid at the time
the government obligations are repurchased rather than interest paid by the
issuer of the obligations.

         The foregoing is only a summary of some of the important California
state personal income tax considerations generally affecting the California
Municipal Money Market Fund and its shareholders. No attempt is made to present
a detailed explanation of the California state personal income tax treatment of
the Fund or its shareholders, and this discussion is not intended as a
substitute for careful planning. Further, it should be noted that the portion of
the Fund's dividends constituting California exempt-interest dividends is
excludable from income for California state personal income tax purposes only.
Any dividends paid to shareholders subject to California state franchise tax or
California state corporate income tax may therefore be taxed as ordinary
dividends to such purchasers notwithstanding that all or a portion of such
dividends is exempt from California state personal income tax. Accordingly,
potential investors in the Fund, including, in particular, corporate investors
which may be subject to either California franchise tax or California corporate
income tax, should consult their tax advisers with respect to the application of
such taxes to the receipt of Fund dividends and as to their own California state
tax situation, in general.

SPECIAL STATE TAX CONSIDERATIONS PERTAINING TO THE FLORIDA
INTERMEDIATE TAX-EXEMPT FUND

         The State of Florida does not currently impose an income tax on
individuals. Thus, individual shareholders of the Florida Intermediate
Tax-Exempt Fund will not be subject to any Florida income tax on distributions
received from the Fund. However, Florida does currently impose an income tax on
certain


                                      -85-
<PAGE>   178
corporations. Consequently, distributions may be taxable to corporate
shareholders.

         The State of Florida currently imposes an "intangibles tax" at the
annual rate of 2 mills or 0.20% on certain securities and other intangible
assets owned by Florida residents. With respect to the first mill, or first
 .10%, of the intangibles tax, every natural person is entitled each year to an
exemption of the first $20,000 of the value of the property subject to the tax.
A husband and wife filing jointly will have an exemption of $40,000. With
respect to the last 1 mill, or last .10%, of the intangibles tax, every natural
person is entitled each year to an exemption of the first $100,000 of the value
of the property subject to the tax. A husband and wife filing jointly will have
an exemption of $200,000. Notes, bonds and other obligations issued by the State
of Florida or its municipalities, counties, and other taxing districts, or by
the United States Government, its agencies and certain U.S. territories and
possessions (such as Guam, Puerto Rico and the Virgin Islands) as well as cash
are exempt from this intangibles tax. If on December 31 of any year the
portfolio of the Florida Tax-Exempt Fund consists solely of such exempt assets,
then the Fund's shares will be exempt from the Florida intangibles tax payable
in the following year.

         In order to take advantage of the exemption from the intangibles tax in
any year, the Fund must sell any non-exempt assets held in its portfolio during
the year and reinvest the proceeds in exempt assets including cash prior to
December 31. Transaction costs involved in restructuring the portfolio in this
fashion would likely reduce the Fund's investment return and might exceed any
increased investment return the Fund achieved by investing in non-exempt assets
during the year.

         Outside the State of Florida, income distributions may be taxable to
shareholders under state or local law as dividend income even though all or a
portion of such distributions may be derived from interest on tax-exempt
obligations or U.S. Government obligations which, if realized directly, would be
exempt from such income taxes. Shareholders are advised to consult their tax
advisers concerning the application of state and local taxes.


                              DESCRIPTION OF SHARES

         The Trust Agreement permits Northern Funds' 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. Northern Funds may hereafter create series in addition to Northern
Funds' existing series, which represent interests in nineteen portfolios, each
of which is discussed in this Additional Statement. Under the terms of the Trust
Agreement, each share of each Fund has a par value of


                                      -86-
<PAGE>   179
$.0001, represents a proportionate interest in the particular Fund with each
other share of its class and is entitled to such dividends and distributions out
of the income belonging to the Fund as are declared by the Trustees. Upon any
liquidation of a Fund, shareholders of each class of a Fund 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 "Redeeming and Exchanging Shares" in the
Prospectus. Pursuant to the terms of the 1940 Act, the right of a shareholder to
redeem shares and the date of payment by a Fund 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 Fund 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 Fund 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 Fund.
Northern Funds may also suspend or postpone the recordation of the transfer of
its shares upon the occurrence of any of the foregoing conditions. In addition,
Northern Funds reserves the right to adopt, by action of the Trustees, a policy
pursuant to which it may, without shareholder approval, redeem upon not less
than 30 days' notice all of a Fund's shares if such shares have an aggregate
value below a designated amount and if the Trustees determine that it is not
practical, efficient or advisable to continue the operation of such Fund and
that any applicable requirements of the 1940 Act have been met. Shares when
issued as described in the Prospectus are validly issued, fully paid and
nonassessable, except as stated below.

         The proceeds received by each Fund 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 Fund. The underlying assets of
each Fund will be segregated on the books of account, and will be charged with
the liabilities in respect to that Fund and with a share of the general
liabilities of Northern Funds. Expenses with respect to the portfolios of
Northern Funds 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 Northern Funds 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


                                      -87-
<PAGE>   180
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, a distribution plan subject to Rule 12b-1 under the 1940 Act 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 may be
effectively acted upon by shareholders of Northern Funds voting together in the
aggregate without regard to a particular investment portfolio.

         The term "majority of the outstanding shares" of either Northern Funds
or a particular Fund or investment portfolio means, with respect to the approval
of an investment advisory agreement, a distribution plan or a change in a
fundamental investment policy, the vote of the lesser of (i) 67% or more of the
shares of Northern Funds or such Fund or portfolio present at a meeting, if the
holders of more than 50% of the outstanding shares of Northern Funds or such
Fund or portfolio are present or represented by proxy, or (ii) more than 50% of
the outstanding shares of Northern Funds or such Fund or portfolio.

   
         As of September 30, 1996, Northern and its affiliates held of record
substantially all of the outstanding shares of the Non-Money Market Funds as
agent, custodian, trustee or investment adviser on behalf of their customers. At
such date, The Northern Trust Company, 50 S. LaSalle Street, Chicago, Illinois
60657, and its affiliate banks held as beneficial owner five percent or more of
the outstanding shares of the Non-Money Market Funds because they possessed
sole or shared voting or investment power with respect to such shares. As of
September 30, 1996, the name and share ownership of the entities or individuals
which held of record or beneficially more than 5% of the outstanding shares of
the Money Market Fund were as follows: Northern Trust Bank--Miami on behalf of
its customers, 23.25% and O.L. Thorne FBO Honore Wamsler, 7.82%. As of
September 30, 1996, the name and share ownership of the entities or individuals
which held of record or beneficially more than 5% of the outstanding shares of
the U.S. Government Money Market Fund were as follows: Sunstone Investor
Services LLC on behalf of of its customers, 9.56% and Northern Trust
Bank--Miami on behalf of its customers, 10.98%. As of September 30, 1996, the
name and share ownership of the entities or individuals which held of record or

Rev. Tr. Frank Hood, 8.75% and RCR Holdings, 5.84%

The address of all of the above persons is c/o The Northern Trust Bank, 50 S.
LaSalle Street, Chicago, Illinois 60657.
    

         As a general matter, Northern Funds does not hold annual or other
meetings of shareholders. This is because the Trust Agreement provides for
shareholder voting only for the election or removal of one or more Trustees, if
a meeting is called for that purpose, and for certain other designated matters.
Each Trustee serves until the next meeting of shareholders, if any, called for
the purpose of considering the election or reelection of such Trustee or of a
successor to such Trustee, and until the election and qualification of his
successor, if any, elected at such meeting, or until such Trustee sooner dies,
resigns, retires or is removed by the shareholders or two-thirds of the
Trustees.

         Under Massachusetts law, there is a possibility that shareholders of a
business trust could, under certain circumstances, be held personally liable as
partners for the obligations of the trust. The Trust Agreement contains an
express disclaimer of shareholder (as well as Trustee and officer) liability for
acts or obligations of Northern Funds and requires that notice of such
disclaimer be given in each contract, undertaking or instrument entered into or
executed by Northern Funds or the Trustees. The Trust Agreement provides for
indemnification out of Trust property of any shareholder charged or held
personally liable for the obligations or liabilities of Northern Funds solely by
reason of being or having been a


                                      -89-
<PAGE>   182
shareholder of Northern Funds and not because of such shareholder's acts or
omissions or for some other reason. The Trust Agreement also provides that
Northern Funds shall, upon proper and timely request, assume the defense of any
charge made against any shareholder as such for any obligation or liability of
Northern Funds and satisfy any judgment thereon. Thus, the risk of a shareholder
incurring financial loss on account of shareholder liability is limited to
circumstances in which Northern Funds itself would be unable to meet its
obligations.

         The Trust Agreement provides that each Trustee of Northern Funds will
be liable for his own wilful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of the office of
Trustee ("disabling conduct"), and for nothing else, and will not be liable for
errors of judgment or mistakes of fact or law. The Trust Agreement provides
further that Northern Funds will indemnify Trustees and officers of Northern
Funds against liabilities and expenses incurred in connection with litigation
and other proceedings in which they may be involved (or with which they may be
threatened) by reason of their positions with Northern Funds, except that no
Trustee or officer will be indemnified against any liability to Northern Funds
or its shareholders to which he would otherwise be subject by reason of
disabling conduct.

         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.

COMMERCIAL PAPER RATINGS

                  A Standard & Poor's commercial paper rating is a current
assessment of the likelihood of timely payment of debt considered short-term in
the relevant market. The following summarizes the rating categories used by
Standard and Poor's for commercial paper:

                  "A-1" - Issue's degree of safety regarding timely payment
is strong.  Those issues determined to possess extremely strong
safety characteristics are denoted "A-1+."

                  "A-2" - Issue's capacity for timely payment is
satisfactory.  However, the relative degree of safety is not as
high as for issues designated "A-1."

                  "A-3" - Issue has an adequate capacity for timely payment. It
is, however, somewhat more vulnerable to the adverse effects of changes in
circumstances than an obligation carrying a higher designation.

                  "B" - Issue has only a speculative capacity for timely
payment.

                  "C" - Issue has a doubtful capacity for payment.

                  "D" - Issue is in payment default.


                  Moody's commercial paper ratings are opinions of the ability
of issuers to repay punctually promissory obligations not having an original
maturity in excess of 9 months. The following summarizes the rating categories
used by Moody's for commercial paper:

                  "Prime-1" - Issuer or related supporting institutions are
considered to have a superior capacity for repayment of short-term promissory
obligations. Prime-1 repayment capacity will normally 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.

                  "Prime-2" - Issuer or related supporting institutions are
considered to have a 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


                                       A-1
<PAGE>   185
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 alternative liquidity is maintained.

                  "Prime-3" - Issuer or related supporting institutions have an
acceptable capacity for repayment of short-term promissory obligations. The
effects of industry characteristics and market composition may be more
pronounced. Variability in earnings and profitability may result in changes in
the level of debt protection measurements and the requirement for relatively
high financial leverage. Adequate alternate liquidity is maintained.

                  "Not Prime" - Issuer does not fall within any of the Prime
rating categories.


                  The three rating categories of Duff & Phelps for investment
grade commercial paper and short-term debt are "D-1," "D-2" and "D-3." Duff &
Phelps employs three designations, "D-1+," "D-1" and "D-1-," within the highest
rating category. The following summarizes the rating categories used by Duff &
Phelps for commercial paper:

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

                  "D-1" - Debt possesses very high certainty of timely payment.
Liquidity factors are excellent and supported by good fundamental protection
factors. Risk factors are minor.

                  "D-1-" - Debt possesses high certainty of timely payment.
Liquidity factors are strong and supported by good fundamental protection
factors. Risk factors are very small.

                  "D-2" - Debt possesses good certainty of timely payment.
Liquidity factors and company fundamentals are sound. Although ongoing funding
needs may enlarge total financing requirements, access to capital markets is
good. Risk factors are small.

                  "D-3" - Debt possesses satisfactory liquidity, and other
protection factors qualify issue as investment grade. Risk factors are larger
and subject to more variation. Nevertheless, timely payment is expected.

                  "D-4" - Debt possesses speculative investment characteristics.
Liquidity is not sufficient to ensure against disruption in debt service.
Operating factors and market access may be subject to a high degree of
variation.


                                       A-2
<PAGE>   186
                  "D-5" - Issuer has failed to meet scheduled principal and/or
interest payments.


                  Fitch short-term ratings apply to debt obligations that are
payable on demand or have original maturities of generally up to three years.
The following summarizes the rating categories used by Fitch for short-term
obligations:

                  "F-1+" - Securities possess exceptionally strong credit
quality. Issues assigned this rating are regarded as having the strongest degree
of assurance for timely payment.

                  "F-1" - Securities possess very strong credit quality. Issues
assigned this rating reflect an assurance of timely payment only slightly less
in degree than issues rated "F-1+."

                  "F-2" - 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 "F-1+" and "F-1" categories.

                  "F-3" - Securities possess fair credit quality. Issues
assigned this rating have characteristics suggesting that the degree of
assurance for timely payment is adequate; however, near-term adverse changes
could cause these securities to be rated below investment grade.

                  "F-S" - Securities possess weak credit quality. Issues
assigned this rating have characteristics suggesting a minimal degree of
assurance for timely payment and are vulnerable to near-term adverse changes in
financial and economic conditions.

                  "D" - Securities are in actual or imminent payment default.

                  Fitch may also use the symbol "LOC" with its short-term
ratings to indicate that the rating is based upon a letter of credit issued by a
commercial bank.


                  Thomson BankWatch short-term ratings assess the likelihood of
an untimely or incomplete payment of principal or interest of unsubordinated
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. The following summarizes the ratings used by Thomson
BankWatch:

                  "TBW-1" - This designation represents Thomson BankWatch's
highest rating category and indicates a very high degree of


                                       A-3
<PAGE>   187
likelihood that principal and interest will be paid on a timely basis.

                  "TBW-2" - This 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."

                  "TBW-3" - This designation represents the lowest investment
grade category and indicates that while the debt is more susceptible to adverse
developments (both internal and external) than obligations with higher ratings,
capacity to service principal and interest in a timely fashion is considered
adequate.

                  "TBW-4" - This designation indicates that the debt is regarded
as non-investment grade and therefore speculative.


CORPORATE AND MUNICIPAL LONG-TERM DEBT RATINGS

                  The following summarizes the ratings used by Standard & Poor's
for corporate and municipal debt:

                  "AAA" - This designation represents the highest rating
assigned by Standard & Poor's to a debt obligation and indicates an extremely
strong capacity to pay interest and repay principal.

                  "AA" - Debt is considered to have a very strong capacity to
pay interest and repay principal and differs from AAA issues only in small
degree.

                  "A" - Debt is considered to have a strong capacity to pay
interest and repay principal although such issues are somewhat more susceptible
to the adverse effects of changes in circumstances and economic conditions than
debt in higher-rated categories.

                  "BBB" - Debt is regarded as having an adequate capacity to pay
interest and repay principal. Whereas such issues normally exhibit adequate
protection parameters, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity to pay interest and repay principal
for debt in this category than in higher-rated categories.

                  "BB," "B," "CCC," "CC" and "C" - Debt 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. "BB" indicates the
lowest degree of speculation and "C" the highest degree of speculation. While
such debt will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions.


                                       A-4
<PAGE>   188
                  "BB" - Debt has less near-term vulnerability to default than
other speculative issues. However, it faces major ongoing uncertainties or
exposure to adverse business, financial or economic conditions which could lead
to inadequate capacity to meet timely interest and principal payments. The "BB"
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied "BBB-" rating.

                  "B" - Debt has a greater vulnerability to default but
currently has the capacity to meet interest payments and principal repayments.
Adverse business, financial or economic conditions will likely impair capacity
or willingness to pay interest and repay principal. The "B" rating category is
also used for debt subordinated to senior debt that is assigned an actual or
implied "BB" or "BB-" rating.

                  "CCC" - Debt has a currently identifiable vulnerability to
default, and is dependent upon favorable business, financial and economic
conditions to meet timely payment of interest and repayment of principal. In the
event of adverse business, financial or economic conditions, it is not likely to
have the capacity to pay interest and repay principal. The "CCC" rating category
is also used for debt subordinated to senior debt that is assigned an actual or
implied "B" or "B-" rating.

                  "CC" - This rating is typically applied to debt subordinated
to senior debt that is assigned an actual or implied "CCC" rating.

                  "C" - This rating is typically applied to debt subordinated to
senior debt which is assigned an actual or implied "CCC-" debt rating. The "C"
rating may be used to cover a situation where a bankruptcy petition has been
filed, but debt service payments are continued.

                  "CI" - This rating is reserved for income bonds on which no
interest is being paid.

                  "D" - Debt is in payment default. This rating is used when
interest payments or principal payments are not made on the date due, even if
the applicable grace period has not expired, unless S & P believes that such
payments will be made during such grace period. "D" rating is also used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

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

                  "r" - This rating is attached to highlight derivative, hybrid,
and certain other obligations that S & P believes may experience high volatility
or high variability in expected returns


                                       A-5
<PAGE>   189
due to non-credit risks. Examples of such obligations are: securities whose
principal or interest return is indexed to equities, commodities, or currencies;
certain swaps and options; and interest only and principal only mortgage
securities. The absence of an "r" symbol should not be taken as an indication
that an obligation will exhibit no volatility or variability in total return.

         The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt:

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

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

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

                  "Baa" - Bonds 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," "B," "Caa," "Ca," and "C" - 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; "Caa" represents a poor standing; "Ca"
represents obligations which are speculative in a high degree; and "C"
represents the lowest rated class of bonds). "Caa," "Ca" and "C" bonds may be in
default.

                  Con. (---) - Bonds for which the security depends upon
the completion of some act or the fulfillment of some condition are


                                       A-6
<PAGE>   190
rated conditionally. These are bonds secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operation experience, (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

                  (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.

                  The following summarizes the long-term debt ratings used by
Duff & Phelps for corporate and municipal long-term debt:

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

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

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

                  "BBB" - Debt possesses below average protection factors but
such protection factors are still considered sufficient for prudent investment.
Considerable variability in risk is present during economic cycles.

                  "BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of
these ratings is considered to be below investment grade. Although below
investment grade, debt rated "BB" is deemed likely to meet obligations when due.
Debt rated "B" possesses the risk that obligations will not be met when due.
Debt rated "CCC" is well below investment grade and has considerable uncertainty
as to timely payment of principal, interest or preferred dividends. Debt rated
"DD" is a defaulted debt obligation, and the rating "DP" represents preferred
stock with dividend arrearages.

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


                  The following summarizes the highest four ratings used by
Fitch for corporate and municipal bonds:


                                       A-7
<PAGE>   191
                  "AAA" - Bonds considered to be investment grade and of the
highest credit quality. The obligor has an exceptionally strong ability to pay
interest and repay principal, which is unlikely to be affected by reasonably
foreseeable events.

                  "AA" - Bonds considered to be investment grade and of very
high credit quality. The obligor's ability to pay interest and repay principal
is very strong, although not quite as strong as bonds rated "AAA." 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+."

                  "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
satisfactory credit quality. The obligor's ability to pay interest and repay
principal is considered to be adequate. Adverse changes in economic conditions
and circumstances, however, are more likely to have an adverse impact on these
bonds, and therefore, impair timely payment. The likelihood that the ratings of
these bonds will fall below investment grade is higher than for bonds with
higher ratings.

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

                  "BB," "B," "CCC," "CC," "C," "DDD," "DD," and "D" - Bonds that
possess one of these ratings are considered by Fitch to be speculative
investments. The ratings "BB" to "C" represent Fitch's assessment of the
likelihood of timely payment of principal and interest in accordance with the
terms of obligation for bond issues not in default. For defaulted bonds, the
rating "DDD" to "D" is an assessment of the ultimate recovery value through
reorganization or liquidation.


MUNICIPAL NOTE RATINGS

                  A Standard and Poor's rating reflects the liquidity concerns
and market access risks unique to notes due in three years or less. The
following summarizes the ratings used by Standard & Poor's Ratings Group for
municipal notes:

                  "SP-1" - The issuers of these municipal notes exhibit very
strong or strong capacity to pay principal and interest.


                                       A-8
<PAGE>   192
Those issues determined to possess overwhelming safety characteristics are given
a plus (+) designation.

                  "SP-2" - The issuers of these municipal notes exhibit
satisfactory capacity to pay principal and interest.

                  "SP-3" - The issuers of these municipal notes exhibit
speculative capacity to pay principal and interest.


                  Moody's ratings for state and municipal notes and other
short-term loans are designated Moody's Investment Grade ("MIG") and variable
rate demand obligations are designated Variable Moody's Investment Grade
("VMIG"). Such ratings recognize the differences between short-term credit risk
and long-term risk. The following summarizes the ratings by Moody's Investors
Service, Inc. for short-term notes:

                  "MIG-1"/"VMIG-1" - Loans bearing this designation are of the
best quality, enjoying strong protection by established cash flows, superior
liquidity support or demonstrated broad-based access to the market for
refinancing.

                  "MIG-2"/"VMIG-2" - Loans bearing this designation are of high
quality, with margins of protection ample although not so large as in the
preceding group.

                  "MIG-3"/"VMIG-3" - Loans bearing this designation are of
favorable quality, with all security elements accounted for but lacking the
undeniable strength of the preceding grades. Liquidity and cash flow protection
may be narrow and market access for refinancing is likely to be less well
established.

                  "MIG-4"/"VMIG-4" - Loans bearing this designation are of
adequate quality, carrying specific risk but having protection commonly regarded
as required of an investment security and not distinctly or predominantly
speculative.

                  "SG" - Loans bearing this designation are of speculative
quality and lack margins of protection.


                  Fitch and Duff & Phelps use the short-term ratings described
under Commercial Paper Ratings for municipal notes.


                                       A-9
<PAGE>   193
                                   APPENDIX B


                  As stated in the Prospectus, the Funds (other than the Money
Market Funds) may enter into certain futures transactions.
Such transactions are described 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 five 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 Fund may use interest rate futures
contracts as a defense, or hedge, against anticipated interest rate changes and
not for speculation. As described below, this would include the use of futures
contract sales to protect against expected increases in interest rates and
futures contract purchases to offset the impact of interest rate declines.

                  A Fund 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 the Fund, by using futures
contracts.

                  Description of Interest Rate Futures Contracts. An interest
rate futures contract sale would create an obligation by a Fund, 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 Fund, 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.


                                       B-1
<PAGE>   194
                  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 the settlement date without the making or taking of delivery
of securities. Closing out a futures contract sale is effected by the Fund
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 the sale exceeds the price of the offsetting purchase, the Fund is
immediately paid the difference and thus realizes a gain. If the offsetting
purchase price exceeds the sale price, the Fund pays the difference and realizes
a loss. Similarly, the closing out of a futures contract purchase is effected by
the Fund entering into a futures contract sale. If the offsetting sale price
exceeds the purchase price, the Fund realizes a gain, and if the purchase price
exceeds the offsetting sale price, the Fund 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.
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 U.S. Treasury Bonds and Notes;
Government National Mortgage Association (GNMA) modified pass-through mortgage
backed securities; three-month U.S. Treasury Bills; and ninety-day commercial
paper. The Funds 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
stocks or bonds included in the index, which fluctuates with changes in the
market values of the stocks or bonds included. Some stock index futures
contracts are based on broad market indexes, such as Standard & Poor's 500 or
the New York Stock Exchange Composite Index. In contrast, certain exchanges
offer futures contracts on narrower market indexes, such as the Standard &
Poor's 100 or indexes based on an industry or market indexes, such as Standard &
Poor's 100 or indexes based on an industry or market segment, such as oil and
gas stocks. Futures contracts are traded on organized exchanges regulated by the
commodity Futures Trading Commission. Transactions on such exchanges are cleared
through a clearing corporation, which guarantees the performance of the parties
to each contract. With regard to each Fund, to the extent consistent with its
investment objective, Northern Trust anticipates engaging in transactions, from
time to time, in foreign stock index futures such as the ALL-ORDS (Australia),
CAC-40 (France), TOPIX (Japan) and the FTSE-100 (United Kingdom).


                                       B-2
<PAGE>   195
                  A Fund 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 Fund 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 Fund
will purchase index futures contracts in anticipation of purchases of
securities. A long futures position may be terminated without a corresponding
purchase of securities.

                  In addition, a Fund may utilize index futures contracts in
anticipation of changes in the composition of its portfolio holdings. For
example, in the event that a Fund 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 Fund
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.

III.     Futures Contracts on Foreign Currencies

                  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 Fund to
hedge against exposure to fluctuations in exchange rates between the U.S. dollar
and other currencies arising from multinational transactions.

IV.  Margin Payments

                  Unlike purchase or sales of portfolio securities, no price is
paid or received by a Fund upon the purchase or sale of a futures contract.
Initially, a Fund will be required to deposit with the broker or in a segregated
account with a custodian an amount of cash or cash equivalents, 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 Fund 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 Fund has purchased a
futures contract and the


                                       B-3
<PAGE>   196
price of the contract has risen in response to a rise in the underlying
instruments, that position will have increased in value and the Fund will be
entitled to receive from the broker a variation margin payment equal to that
increase in value. Conversely, where the Fund 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 Fund
would be required to make a variation margin payment to the broker. Prior to
expiration of the futures contract, Northern Trust 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 Fund'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 Fund, and the Fund
realizes a loss or gain.

V.  Risks of Transactions in Futures Contracts

                  There are several risks in connection with the use of futures
by a Fund as a hedging device. 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 Fund 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 Fund 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, a Fund 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 Northern Trust. Conversely, a Fund 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 Northern Trust. It is also possible that, where a Fund has sold
futures to hedge its portfolio against a decline in the market, the market may
advance and the value of instruments held in the Fund may decline. If this
occurred, the Fund would


                                       B-4
<PAGE>   197
lose money on the futures and also experience a decline in value in its
portfolio securities.

                  When futures are purchased to hedge against a possible
increase in the price of securities or a currency before a Fund is able to
invest its cash (or cash equivalents) in an orderly fashion, it is possible that
the market may decline instead; if the Fund then concludes not to invest its
cash at that time because of concern as to possible further market decline or
for other reasons, the Fund 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 adviser 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
Funds 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, a Fund 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 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


                                       B-5
<PAGE>   198
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 a Fund is also subject to
Northern Trust's ability to predict correctly movements in the direction of the
market. For example, if a particular Fund has hedged against the possibility of
a decline in the market adversely affecting securities held by it and securities
prices increase instead, the Fund 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 Fund 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. A Fund may
have to sell securities at a time when it may be disadvantageous to do so.

VI.  Options on Futures Contracts

                  A Fund 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 Fund 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


                                       B-6
<PAGE>   199
margin deposits. As an example, in anticipation of a decline in interest rates,
a Fund may purchase call options on futures contracts as a substitute for the
purchase of futures contracts to hedge against a possible increase in the price
of securities which the Fund intends to purchase. Similarly, if the value of the
securities held by a Fund is expected to decline as a result of an increase in
interest rates, the Fund might purchase put options or sell call options on
futures contracts rather than sell futures contracts.

                  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). 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 the securities being hedged, an option may or may not be less risky
than ownership of the futures contract or such securities. 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 frequently involve less potential risk to the Fund 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.

                        NOTES TO THE FINANCIAL STATEMENTS

                               SEPTEMBER 30, 1996
                                   (UNAUDITED)


1.  ORGANIZATION

Northern Funds was organized October 12, 1993 as a Massachusetts business trust
and is registered under the Investment Company Act of 1940 as an open-end
management investment company consisting of 18 portfolios. The Technology Fund
(the "Fund") is a separate, diversified investment portfolio of Northern Funds.
The Fund seeks long-term capital appreciation by investing principally in equity
securities and securities convertible into common stock of companies that
develop, produce or distribute products and services related to advances in
technology. The Fund commenced investment operations on April 1, 1996.

The Fund has entered into an Investment Advisory Agreement with The Northern
Trust Company ("Northern Trust" or the "Adviser"). Northern Trust also serves as
custodian, fund accountant and transfer agent for the Fund.


2.  SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its 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.

a. VALUATION OF SECURITIES - Short-term investments held by the Fund are valued
using the amortized cost method, which approximates market value. 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 to maturity. Securities which are traded on a recognized
U.S. or foreign securities exchange are generally valued at the last quoted
sales price on the securities exchange on which the securities are primarily
traded. If securities traded on a foreign securities exchange are not traded on
a valuation date, they will be valued at the most recent quoted sales price.
Securities that are traded in the U.S. over-the-counter markets, absent a last
quoted sales price, are valued at the last quoted bid price. Securities which
are traded in the foreign over-the-counter markets are generally valued at the
last sales price. Any securities for

                            NORTHERN TECHNOLOGY FUND
                  NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

                               SEPTEMBER 30, 1996
                                   (UNAUDITED)


which no current quotations are readily available are valued at fair value as
determined in good faith by the Adviser under the supervision of the Board of
Trustees.

b. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded as
of the trade date. The Fund determines the gain or loss realized from investment
transactions by using an identified cost basis method. Dividend income is
recognized on the ex-dividend date and interest income is recognized on an
accrual basis and includes amortization of discounts and premiums. Dividends
from foreign securities are recorded on ex-date, or as soon as the information
is available.

c. EXPENSES - The Fund is charged for those expenses that are directly
attributable to the Fund. Expenses that are not directly attributable to the
Fund are typically allocated among the Northern Funds in proportion to their
respective net assets.

d. DISTRIBUTIONS TO SHAREHOLDERS - Dividends from net investment income are
declared and paid annually. Distributions of net realized capital gains, if any,
are declared at least annually. Distributions to shareholders are recorded on
the ex-dividend date. No dividends or distributions were paid during the six
months ended September 30, 1996.

e. FEDERAL INCOME TAXES - No provision for federal income taxes has been made
since the Fund intends to comply with the requirements of the Internal Revenue
Code available to regulated investment companies and to distribute substantially
all of its taxable income to its shareholders.


3.  INVESTMENT ADVISORY AND OTHER AGREEMENTS

Pursuant to its advisory agreement with the Fund, the Adviser is entitled to
receive a fee, calculated daily and payable monthly, at the annual rate of 1.20%
as applied to the Fund's daily net assets. For the six months ended September
30, 1996, the Adviser voluntarily agreed to waive a portion of its advisory fees
as applied to the Fund's daily net assets, resulting in a net advisory fee after
waivers of 1.00%. For the six months ended September 30, 1996, Northern Trust
had also agreed to reimburse the Fund as shown on the accompanying Statement of
Operations to adhere to the expense limitation of 1.25%.

The Fund has entered into an administrative agreement with Sunstone Financial
Group, Inc. ("Sunstone") for certain administrative services. Pursuant to its
administrative agreement with the Fund, Sunstone is entitled to receive a fee,
computed daily and

4.  BANK LOANS

Northern Funds 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

outstanding balance.

There were no borrowings under the agreement during the six months ended
September 30, 1996.

5.   INVESTMENT TRANSACTIONS
      (amounts in thousands)

The aggregate purchases and sales of securities, excluding short-term
investments, for the Fund for the six months ended September 30, 1996, were
$21,346 and $1,989, respectively. For the six months ended September 30, 1996
there were no purchases or sales of U.S. Treasury obligations.

                  6.3 Indemnification of Shareholders. No Shareholder shall be
                  subject to any personal liability whatsoever to any person in
                  connection with property of the Trust or the acts, obligations
                  or affairs of the Trust or any Series thereof. The Trust shall

                  all legal and other expenses reasonably incurred by him in

                  indemnification and reimbursement required by the preceding
                  sentence shall be made only out of assets of the one or more
                  Series whose Shares were held by said Shareholder at the time
                  the act or event occurred which gave rise to the claim against
                  or liability of said Shareholder. The rights accruing to a
                  Shareholder under this Section shall not impair any other
                  right to which such Shareholder may be lawfully entitled, nor
                  shall anything herein contained restrict the right of the
                  Trust or any Series thereof to indemnify or reimburse a
                  Shareholder in any appropriate situation even though not

                  6.4 Indemnification of Trustees, Officers, etc. The Trust
                  shall indemnify each of its Trustees and officers and persons
                  who serve at the Trust's request as directors, officers or
                  trustees of another organization in which the Trust has any
                  interest as a shareholder, creditor or otherwise (hereinafter
                  referred to as a "Covered Person") against all liabilities,
                  including but not limited to amounts paid in satisfaction of
                  judgments, in compromise or as fines and penalties, and
                  expenses, including reasonable accountants' and counsel fees,
                  incurred by any Covered Person in connection with the defense
                  or disposition of any action, suit or other proceeding,
                  whether civil or criminal, before any court or administrative
                  or legislative body, in which such Covered Person may be or
                  may have been involved as a party or otherwise or with which
                  such person may be or may have been threatened, while in
                  office or thereafter, by reason of being or having been such a
                  Trustee or officer, director or trustee, except that no
                  Covered Person shall be indemnified against any liability to
                  the Trust or its Shareholders to which such Covered Person
                  would otherwise be subject by reason of wilful misfeasance,
                  bad faith, gross negligence or reckless disregard of the
                  duties involved in the conduct of such Covered Person's office
                  (such wilful misfeasance, bad faith, gross negligence or
                  reckless disregard being referred to herein as "Disabling
                  Conduct"). Expenses, including accountants' and counsel fees
                  so incurred by any such Covered Person (but excluding amounts
                  paid in satisfaction of judgments, in compromise or as fines
                  or penalties), may be paid from time to time by the

                  Trust in advance of the final disposition of any such action,
                  suit or proceeding upon receipt of (a) an undertaking by or on
                  behalf of such Covered Person to repay amounts so paid to the
                  Trust if it is ultimately determined that indemnification of
                  such expenses is not authorized under this Article VI and
                  either (b) such Covered Person provides security for such
                  undertaking, (c) the Trust is insured against losses arising
                  by reason of such payment, or (d) a majority of a quorum of
                  disinterested, non-party Trustees, or independent legal
                  counsel in a written opinion, determines, based on a review of
                  readily available facts, that there is reason to believe that
                  such Covered Person ultimately will be found entitled to
                  indemnification.

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


ITEM 28. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER


                  The Northern Trust Bank, Registrant's investment adviser, is a

                           the Investment Adviser, and the Investment Adviser
