                       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 Fundhas 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 Fundseeks 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.




                                      -4-

                          Short-Intermediate U.S. Government Fund seeks high
                          current income from a broad range of U.S. Government
                          securities.  The Fund's dollar-weighted average
                          maturity is anticipated to range between two and five
                          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
                          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 and the
                          Short- Intermediate U.S. Government Fund.

                          International Fixed Income Fundseeks 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 Fundseeks high current income
                          exempt from regular federal income tax by investing
                          in a broad range of Municipal Instruments with an
                          expected average maturity of three to ten years.

                          Florida Intermediate Tax-Exempt Fundseeks high
                          current income exempt from regular federal income tax
                          by investing in Municipal Instruments with an
                          expected average maturity of three to ten years.  The
                          Fund intends, but cannot guarantee, that its shares
                          will qualify for exemption from the Florida
                          intangibles tax.

                          California Intermediate Tax-Exempt Fund seeks high
                          current income exempt from regular federal income tax
                          and California state personal income tax by investing
                          in Municipal Instruments with an expected average
                          maturity of three to ten years.

                          Tax-Exempt Fund 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.

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

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

                 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
                          Funds' 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
                          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 Morgan Stanley
                          High-Technology 35 Index (the "Morgan Stanley
                          Index"), the Hambrecht and Quist Technology Index
                          (the "H&Q Index"), the SoundView Technology Index,
                          the technology grouping of the S&P 500 Index or any
                          other comparable index.


                          The Morgan Stanley Index is a broad-market technology
                          indicator dedicated exclusively to the
                          electronics-based technology sector.  The 35 stocks
                          in the Index include the most highly capitalized
                          American companies drawn from nine technology
                          subsectors:  computer services/design software,
                          server software, PC software and new media,
                          networking and telecom equipment, server hardware, PC
                          hardware and peripherals, specialized systems and
                          semi-conductors.  The SoundView Technology Index
                          includes approximately 100 companies from the design,
                          automation, communications, mainframe

                          semiconductor, software and related services
                          industries.  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 Morgan
                          Stanley, 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.

                          Small Cap Index Fund seeks to provide investment
                          results approximating the aggregate price and
                          dividend performance of the securities included in
                          the Russell 2000 Small Stock Index (the "Russell
                          Index").

         COMMERCIAL PAPER, BANKERS' ACCEPTANCES, CERTIFICATES OF  DEPOSIT, TIME
DEPOSITS AND BANK NOTES.  Commercial paper represents short-term unsecured
promissory notes issued in bearer form by banks or bank holding companies,
corporations and finance companies.  Certificates of deposit are negotiable
certificates issued against funds deposited in a commercial bank for a definite
period of time and earning a specified return.  Bankers' acceptances are
negotiable drafts or bills of exchange, normally drawn by an importer or
exporter to pay for specific merchandise, which are "accepted" by a bank,
meaning, in effect, that the bank unconditionally agrees to pay the face value
of the instrument on maturity.  Fixed time deposits are bank obligations
payable at a stated maturity date and bearing interest at a fixed rate.  Fixed
time deposits may be withdrawn on demand by the investor, but may be subject to
early withdrawal penalties that vary depending upon market conditions and the
remaining maturity of the obligation.  There are no contractual restrictions on
the right to transfer a beneficial interest in a fixed time deposit to a third
party.  Bank notes 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 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 may not exist.
         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





                                      -9-
<PAGE>   10

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 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 liquid
assets in 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 and ability to meet payment on demand.  In determining weighted average
portfolio maturity, an instrument may, subject to applicable Securities and
Exchange Commission ("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





                                      -10-
<PAGE>   11
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 liquid assets 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 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.  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 





                                      -11-
<PAGE>   12
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 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





                                      -12-
<PAGE>   13

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 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, Florida and Arizona 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.





                                      -13-
<PAGE>   14
         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.

         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, Florida Intermediate Tax-Exempt, Tax-Exempt, Arizona Tax-Exempt,
California Municipal Money Market and California 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, Florida
Intermediate Tax-Exempt Fund, California Intermediate Tax-Exempt Fund,
Tax-Exempt Fund, Arizona Tax-Exempt Fund or California 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





                                      -14-
<PAGE>   15

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 Intermediate Tax-Exempt, Florida
Intermediate Tax-Exempt, Tax-Exempt, Arizona Tax-Exempt, Municipal Money
Market, California Intermediate Tax-Exempt and California 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 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 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.  Each Tax-Exempt Fund 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





                                      -15-
<PAGE>   16

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 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.
         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.





                                      -16-
<PAGE>   17

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 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 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.

         A separate account consisting of liquid assets 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, foreign and 





                                      -17-
<PAGE>   18
domestic 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 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, liquid assets 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 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.  





                                      -18-
<PAGE>   19
         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 liquid assets 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 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





                                      -19-
<PAGE>   20
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 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




                                      -20-
<PAGE>   21
   
law.  This is true even if the exchange is formally linked to a domestic market
so that a position taken on the market may be liquidated by a transaction on
another market.  Moreover, such laws or regulations will vary depending on the
foreign country in which the foreign futures or foreign options transaction
occurs.  For these reasons, persons who trade foreign futures or foreign options
contracts may not be afforded certain of the protective measures provided by the
Commodity Exchange Act, the Commodity Futures Trading Commission's ("CFTC")
regulations and the rules of the National Futures Association and any domestic
exchange, including the right to use reparations proceedings before the CFTC and
arbitration proceedings provided them by the National Futures Association or any
domestic futures exchange.  In particular, a Fund's investments in foreign
futures or foreign options transactions may not be provided the same protections
in respect of transactions on United States futures exchanges.  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 and Small Cap Index
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
trusts.  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, U.S.  Government Fund and
Short-Intermediate 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





                                      -21-
<PAGE>   22

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 SWAPS, FLOORS AND CAPS AND CURRENCY SWAPS.  The U.S.
Government, Short Intermediate U.S. Government, Fixed Income, Intermediate
Tax-Exempt, Tax-Exempt, Florida Intermediate Tax-Exempt, California
Intermediate Tax-Exempt, California Tax-Exempt, Arizona Tax- Exempt,
International Fixed Income and Income Equity Funds may enter into interest rate
swaps for hedging purposes and not for speculation.  The U.S. Government,
Short-Intermediate U.S. Government, Fixed Income and International Fixed Income
Funds may also purchase interest rate floors or caps 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 purchase of an interest rate floor or
cap entitles the purchaser to receive payments of interest on a notional
principal amount from the seller, to the extent the specified index falls below
(floor) or exceeds (cap) a predetermined interest rate.  The 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 or interest rate floor
or cap transactions 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 or currency swap will be
accrued on a daily basis, and an amount of liquid assets having an aggregate
net asset value at least equal to such accrued excess, will be maintained in a
segregated account by the Funds' custodian.





                                      -22-
<PAGE>   23

         A Fund will not enter into a currency or interest rate swap or
interest rate floor or cap transaction unless the unsecured commercial paper,
senior debt or the claims-paying ability of the other party thereto is rated
either A or A-1 or better by S&P, Duff or Fitch, or A or P-1 or better by
Moody's.  If there is a default by the other party to such transaction, 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 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, 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





                                      -23-
<PAGE>   24
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.

         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
from 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





                                      -24-
<PAGE>   25

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 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 ratings 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





                                      -25-
<PAGE>   26
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.  To the extent required by the 1940 Act and the
regulations and orders of the SEC thereunder, 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 total outstanding stock of any one investment company
will be owned by a Fund, the 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 or Northern Funds 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 this amount may be illiquid.  Notwithstanding the
foregoing, a Fund may adhere to more restrictive limitations with respect to
its investments in securities issued by other investment companies if required
by the SEC or deemed to be in the best interests of Northern Funds, and will
comply with any fundamental investment restriction that may otherwise be
applicable to such investments.  To the extent required by the 1940 Act, each
Fund expects to vote the shares of other investment companies that are held by
it in the same proportion as the vote of all other holders of such securities.

         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, 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





                                      -26-
<PAGE>   27

   
redemption of shares and by requirements which enable the Funds to receive
favorable tax treatment.  For the fiscal year ended March 31, 1997, the
turnover rates with respect to the U.S. Government, Fixed Income, Intermediate
Tax-Exempt, Florida Intermediate Tax-Exempt, Tax-Exempt, International Fixed
Income, Income Equity, Stock Index, Growth Equity, Select Equity, Small Cap,
International Growth Equity, International Select Equity and Technology Funds
were 83.41%, 87.64%, 61.39%, 50.77%, 8.10%, 37.36%, 72.04%, 45.68%, 67.34%,
72.68%, 18.92%, 190.94%, 97.60% and 67.89%, respectively. The
Short-Intermediate U.S. Government Fund, California Intermediate Tax-Exempt
Fund, Arizona Tax-Exempt Fund, California Tax-Exempt Fund and Small Cap Index
Fund had not commenced operations during the fiscal year ended March 31, 1997.
    

         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, FLORIDA MUNICIPAL INSTRUMENTS AND ARIZONA MUNICIPAL INSTRUMENTS

   
         Some of the risk factors relating to investments by the California,
Florida Intermediate Tax-Exempt and Arizona Tax-Exempt Funds in California,
Florida, and Arizona Municipal Instruments 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

         CALIFORNIA MUNICIPAL INSTRUMENTS

ECONOMIC FACTORS
                 FISCAL YEARS PRIOR TO 1996-97.  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.  Beginning with the 1990-91 Fiscal Year and for
several years thereafter, the budget required multi-billion dollar actions to
bring projected revenues and expenditures into balance.  During this period,
expenditures exceeded revenues in four out of six years, and the State
accumulated and sustained a budget deficit in the Special Fund -- approaching
$2.8 billion at its peak on June 30, 1993.

                 By the 1993-94 Fiscal Year, the accumulated deficit was too
large to be prudently retired in one year and a two-year program was
implemented.  This program used revenue anticipation warrants to carry a
portion of the deficit over to the end of the fiscal year.

                 The 1994-95 Budget Act projected General Fund revenues and
transfers of $41.9 billion.  Expenditures were projected to be $40.9 billion --
an increase of $1.6 billion over the prior year.  As a result of the improving
economy, however, the fiscal year ultimately produced revenues and transfers of
$42.7 billion which more than offset expenditures of $42.0 billion and thereby
reduced the accumulated budget deficit.

                 With strengthening revenues and reduced caseload growth driven
by 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.
The 1995-96 Budget Act projected General Fund revenues and transfers of $44.1
billion, a 3.5 percent increase from the prior year, and expenditures were
budgeted at 




                                      -28-
<PAGE>   29
$43.4 billion.  In addition, 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 as of June 30, 1996.

                 1996-97 FISCAL YEAR.


                 The 1996-97 Governor's Budget, released January 10, 1996,
projected General Fund revenues and transfers of $45.6 billion, a 1.3% increase
over 1995-96.  The Governor's budget proposed two major initiatives, a 15%
personal and corporate income tax cuts and a revision of the trial court
funding program, which would have the effect of reducing General Fund revenues.
The Governor's Budget proposed General Fund expenditures of $45.2 billion.  The
Governor's Budget also proposed Special Fund revenues equal to expenditures, at
a level of $13.3 billion.

                 The May Revision of the Governor's Budget, released on May 21,
1996 ("The May Revision"), updated revenue estimates for the 1996-97 Fiscal
Year, reflecting stronger economic activity in the State and thus greater
revenue growth.  The revised estimate was for $47.1 billion of revenues, still
assuming the Governor's tax cut would be enacted, and $46.5 billion of
expenditures.

                 1996-97 Budget Act

                 The 1996-97 Budget Act was signed by the Governor on July 15,
1996, along with various implementing bills.  The Governor vetoed about $82
million of appropriations (both General Fund and Special Fund).  With the
signing of the Budget Act, the State implemented its regular cash flow
borrowing program with the issuance of $3.0 billion of Revenue Anticipation
Notes to mature on June 30, 1997.  The Budget Act appropriates a budget reserve
in the Special Fund of $305 million, as of June 30, 1997.  The Department of
Finance projects that, on June 30, 1997, the State's available borrowable
(cash) resources will be $2.9 billion, after payment of all obligations due by
that date, so that no cross-fiscal year borrowing is anticipated.

                 Revenues - The Legislature rejected the Governor's proposed
15% cut in personal income taxes (to be phased in over three years), approved a
5% cut in bank and corporation taxes, to be effective for income years
commencing on January 1, 1997.  As a result of the Legislature's failure to
enact the personal income tax cut, revenues for the Fiscal Year are estimated
to be $550 million higher than projected in the May Revision, and are now
estimated to total $47.643 billion, a 3.3 percent increase over the final
estimated 1995-96 revenues.  Special Fund revenues are estimated to be $13.3
billion.  




                                      -29-
<PAGE>   30
                 Expenditures - The Budget Act contains General Fund
appropriations totaling $47.251 billion, a 4.0 percent increase over the final
estimated 1995-96 expenditures.  Special Fund expenditures are budgeted at
$12.6 billion.  

                 The following are principal features of the 1996-97 Budget
Act:

                 1.       Proposition 98 funding for schools and community
college districts increased by almost $1.6 billion (General Fund) and $1.65
billion above revised 1995-96 levels.  Almost half of this money was budgeted
to fund class-size reductions in kindergarten and grades 1- 3.  Also, for the
second consecutive year, the full cost of living allowance (3.2 percent) was
funded. Proposition 98 increases have brought K- 12 expenditures to almost
$4,800 per pupil (also called ADA, or Average Daily Attendance), an almost 15%
increase over the level prevailing during the recession years.  Out of this
$1.6 billion total community colleges will receive an increase in funding of
$157 million for 1996-97.

                 Due to higher than projected revenues in 1995-96, an
additional $1.1 billion ($190 per K-12 ADA and $145 million for community
colleges) was appropriated and retroactively applied towards the 1995-96
Proposition 98 guarantee, bringing K-12 expenditures in that year to over
$4,600 per ADA.  Similar retroactive increases totaling $230 million, based on
final figures on revenues and State population growth, were made to the 1991-92
and the 1994-95 Proposition 98 guarantees, most of which was allocated to each
school site.

                 2.       The Budget Act assumed savings of approximately $660
million in health and welfare costs which required changes in federal law,
including federal welfare reform.  The Budget Act further assumed federal law
changes in August 1996 which would allow welfare cash grant levels to be
reduced by October 1, 1996.  These cuts totaled approximately $163 million of
the anticipated $660 million savings.  See "Federal Welfare Reform".

                 3.       A 4.9 percent increase in funding for the University
of California ($130 million General Fund) and the California State University
system ($101 million General Fund), with no increases in student fees.

                 4.       The Budget Act assumed the federal government will
provide approximately $700 million in new aid for incarceration and health care
costs of illegal immigrants.  These funds reduce appropriations in these
categories that would otherwise have to be paid from the General Fund.  (For
purposes of cash flow projections, the Department of Finance expects $540
million of this amount to be received during the 1996-97 fiscal year.) 




                                      -30-
<PAGE>   31
                 5.       General Fund support for the Department of
Corrections was increased by about 7 percent over the prior year, reflecting
estimates of increased prison population.

                 6.       With respect to aid to local governments, the
principal new programs included in the Budget Act are $100 million in grants to
cities and counties for law enforcement purposes, and budgeted $50 million for
competitive grants to local governments for programs to combat juvenile crime.

                 The Budget Act did not contain any tax increases. As noted,
there was a reduction in bank and corporate taxes.  In addition, the
Legislature approved another one-year suspension of the Renters Tax Credit,
saving $520 million in expenditures.

                 Federal Welfare Reform - Following enactment of the 1996-97
Budget Act, Congress passed and the President signed (on August 22, 1996) the
Personal Responsibility and Work Opportunity Act of 1996 (P.L. 104-193, the
"Law") making a fundamental reform of the current welfare system.  Among many
provisions, the Law includes: (i) conversion of Aid to Families with Dependent
Children from an entitlement program to a block grant titled Temporary
Assistance for Needy Families (TANF), with lifetime time limits on TANF
recipients, work requirements and other changes; (ii) provisions denying
certain federal welfare and public benefits to legal noncitizens, allowing
states to elect to deny additional benefits (including TANF) to legal
noncitizens, and generally denying almost all benefits to illegal immigrants;
and (iii) changes in the Food Stamp program, including reducing maximum
benefits and imposing work requirements.

                 The Law requires states to implement the new TANF program not
later than July 1, 1997 and provides California approximately $3.7 billion in
block grant funds for FY 1996-97.  States are allowed to implement TANF as soon
as possible and will receive a prorated block grant effective the date of
application.  The California State Plan is to be submitted  in time to allow
grant reductions to be implemented effective January 1, 1997 (allowing $92
million of the $163 million referred to in paragraph 2 above to be saved) and
to allow the State to capture approximately $267 million in additional federal
block grant funds over the currently budgeted level.  None of the other federal
changes needed to achieve the balance of the $660 million cost savings were
enacted.  Thus in lieu of the $660 million savings initially assumed to be
saved, it is now projected that savings will total approximately $360 million.

                 A preliminary analysis of the Law by the Legislative Analyst's
Office indicated that an overall assessment of how these changes will affect
the State's General Fund will not be known for some time, and will depend on
how the State implements the Law.  




                                      -31-
<PAGE>   32
There are many choices including how quickly the State implements the Law; the
degree to which the State elects to make up for cuts in federal aid; provide
more aid to counties, or cut some of its own existing programs for noncitizens;
and the State's ability to avoid certain penalties written into the Law.

                 1997-98 FISCAL YEAR PROPOSED BUDGET.

                 On January 9, 1997, the Governor released his proposed budget
for the 1997-98 Fiscal Year (the "Governor's Budget").  The Governor's Budget
projects General Fund revenues and transfers in 1997-98 of $50.7 billion, a
4.6% increase from revised 1996-97 figures.  The Governor proposes expenditures
of $50.3 billion, a 3.9% increase from 1996-97.  The Governor's Budget projects
a balance in the SFEU of $553 million on June 30, 1998.  The Governor's Budget
also anticipates about $3 billion of external borrowing for cash flow purposes
during the year, with no requirement for cross-fiscal year borrowing.

                 Among the major initiatives and features of the Governor's
Budget are the following:

                 1.       A proposed 10% cut in the Bank and Corporation Tax
rate, to be phased in over two years.

                 2.       Proposition 98 funding for K-14 schools will be
increased again, as a result of stronger revenues.  Per-pupil funding for K-12
schools will reach $5,010, compared to $4,220 as recently as the 1993-94 Fiscal
Year.  Part of the new funding is proposed to be dedicated to the completion of
the current program to reduce class size to 20 pupils in lower elementary
grades, and to expand the program by one grade, so that it will cover K-3rd
grade.

                 3.       Funding for higher education will be increased
consistent with a four-year "compact" established in 1995-96.  There is not
projected to be any increase in student fees at any of the three levels of the
State higher education system.

                 4.       The 1997-98 proposed Governor's Budget assumes
approximately $500 million in savings contingent upon federal action.  The
Budget assumes that federal law will be enacted to remove the
maintenance-of-effect requirement for Supplemental Security Income (SSI)
payments, thereby enabling the state to reduce grant levels pursuant to
previously enacted state law ($279 million).  The Budget also assumes the
federal government will fund $216 million in costs of health care for illegal
immigrants.  

                 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





                                      -32-
<PAGE>   33
Bankruptcy Code.  The subsequent restructuring led to the sale of substantially
all of the Pool's portfolio and resulted in losses estimated to be
approximately $1.7 billion (or approximately 22% of amounts deposited by the
Pool investors).  Approximately 187 California public entities -- substantially
all of which are public agencies within the county -- had various bonds, notes
or other forms of indebtedness outstanding.  In some instances the proceeds of
such indebtedness were invested in the Pool.

                 In April, 1996, the County emerged from bankruptcy after
closing on a $900 million recovery bond transaction.  At that time, the County
and its financial advisors stated that the County had emerged from the
bankruptcy without any structural fiscal problems and assured that the County
would not slip back into bankruptcy.  However, for many of the cities, schools
and special districts that lost money in the County portfolio, repayment
remains contingent on the outcome of litigation which is pending against
investment firms and other finance professionals.  Thus, it is impossible to
determine the ultimate impact of the bankruptcy and its aftermath on these
various agencies and their claims.

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

   
                 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. 
    

   
                 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 
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





                                      -33-
<PAGE>   34
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 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 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
    




                                      -34-
<PAGE>   35

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 statutes 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 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.





                                      -35-
<PAGE>   36

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.
    

                 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.

   
                 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.
    




                                      -36-
<PAGE>   37
                 Section 1 of Article XIIIA, as amended, limits the maximum ad
valorem tax on real property to 1% of full cash value to be collected by the
counties and apportioned according to law.  The 1% limitation does not apply to
ad valorem taxes or special assessments to pay the interest and redemption
charges on any bonded indebtedness for the acquisition or improvement of real
property approved 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.

                 Legislation enacted by the California Legislature to implement
Article XIIIA 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.

                 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 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.

                 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




                                      -37-

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 XIII B
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 capita
General Fund revenue growth exceeds per capita personal income growth.

                 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
XIII B limit to K-14 schools.

                 During the recession years of the early 1990s, 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.  In 1992, a lawsuit was filed,
California Teachers' Association v. Gould, which challenged the validity of
these off-budget loans. During the course of this litigation, a trial court
determined that almost $2 billion in "loans" which had been provided to school
districts during the recession violated the constitutional protection of
support for public education.  A settlement was reached on April 12, 1996 which
ensures that future school funding will not be in jeopardy over repayment of
these so-called loans.

                 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
recalculated spending limits for the State and for local





                                      -38-
<PAGE>   39
governments, allowed greater annual increases in the limits, allowed the
averaging of two years' tax revenues before requiring action regarding excess
tax revenues, reduced the amount of the funding 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), removed 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, limited
the amount of State tax revenue over the limit which would be transferred to
school districts and community college districts, and exempted increased
gasoline taxes and truck weight fees from the State appropriations limit.
Additionally, Proposition 111 exempted 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
provided the following:

                 1.       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;

                 2.       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;

                 3.       Restricts the use of revenues from a special tax to
         the purposes or for the service for which the special tax was imposed;

                 4.       Prohibits the imposition of ad valorem taxes on real
         property by local governmental entities except as permitted by Article
         XIIIA;

                 5.       Prohibits the imposition of transaction taxes and
         sales taxes on the sale of real property by local governments;

                 6.       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;

                 7.       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





                                      -39-
<PAGE>   40
         by such entity attributable to the tax levied in violation of the
         initiative; and

                 8.       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
impossible 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.  The
California Court of Appeal in City of Woodlake v. Logan, (1991) 230 Cal.App.3d
1058, subsequently held that Proposition 62's popular vote requirements for
future local taxes also provided for an unconstitutional referenda.  The
California Supreme Court declined to review both the City of Westminster and
the City of Woodlake decisions.

                 In Santa Clara Local Transportation Authority v. Guardino,
(Sept. 28, 1995) 11 Cal.4th 220, reh'g denied, modified (Dec. 14, 1995) 12
Cal.4th 344e, the California Supreme Court upheld the constitutionality of
Proposition 62's popular vote requirements for future taxes, and specifically
disapproved of the City of Woodlake decision as erroneous.  The Court did not
determine the correctness of the City of Westminster decision, because that
case appeared distinguishable, was not relied on by the parties in Guardino,
and involved taxes not likely to still be at issue.  It is impossible to
predict the impact of the Supreme Court's decision on charter cities or on
taxes imposed in reliance on the City of Woodlake case.

                 Senate Bill 1590 (O'Connell), introduced February 16, 1996,
would make the Guardino decision inapplicable to any tax first imposed or
increased by an ordinance or resolution adopted before December 14, 1995.  The
California State Senate passed the Bill on May 16, 1996 and it is currently
pending in the California State Assembly.  It is not clear whether the Bill, if
enacted, would be constitutional as a non-voted amendment to Proposition 62 or
as a non-voted change to Proposition 62's operative date.

                 PROPOSITION 218.  On November 5, 1996,the voters of the State
approved Proposition 218, a constitutional initiative, entitled the "Right to
Vote on Taxes Act" ("Proposition 218").  Proposition 218 adds Articles XIII C
and XIII D to the California 





                                      -40-
<PAGE>   41
Constitution and contains a number of interrelated provisions affecting the
ability of local governments to levy and collect both existing and future
taxes, assessments, fees and charges.  Proposition 218 became effective on
November 6, 1996.  The Sponsors are unable to predict whether and to what
extent Proposition 218 may be held to be constitutional or how its terms will
be interpreted and applied by the courts.  However, if upheld, Proposition 218
could substantially restrict certain local governments' ability to raise future
revenues and could subject certain existing sources of revenue to reduction or
repeal, and increase local government costs to hold elections, calculate fees
and assessments, notify the public and defend local government fees and
assessments in court.

                 Article XIII C of Proposition 218 requires majority voter
approval for the imposition, extension or increase of general taxes and
two-thirds voter approval for the imposition, extension or increase of special
taxes, including special taxes deposited into a local government's general
fund.  Proposition 218 also provides that any general tax imposed, extended or
increased without voter approval by any local government on or after January 1,
1995 and prior to November 6, 1996 shall continue to be imposed only if
approved by a majority vote in an election held within two years of November 6,
1996.

                 Article XIII C of Proposition 218 also expressly extends the
initiative power to give voters the power to reduce or repeal local taxes,
assessments, fees and charges, regardless of the date such taxes, assessments,
fees or charges were imposed.  This extension of the initiative power to some
extent constitutionalizes the March 6, 1995 State Supreme Court decision in
Rossi v. Brown, which upheld an initiative that repealed a local tax and held
that the State constitution does not preclude the repeal, including the
prospective repeal, of a tax ordinance by an initiative, as contrasted with the
State constitutional prohibition on referendum powers regarding statutes and
ordinances which impose a tax.  Generally, the initiative process enables
California voters to enact legislation upon obtaining requisite voter approval
at a general election.  Proposition 218 extends the authority stated in Rossi
v. Brown by expanding the initiative power to include reducing or repealing
assessments, fees and charges, which had previously been considered
administrative rather than legislative matters and therefore beyond the
initiative power.

                 The initiative power granted under Article XIII C of
Proposition 218, by its terms, applies to all local taxes, assessments, fees
and charges and is not limited to local taxes, assessments, fees and charges
that are property related.

                 Article XIII D of Proposition 218 adds several new
requirements making it generally more difficult for local agencies 





                                      -41-
<PAGE>   42
to levy and maintain "assessments" for municipal services and programs.
"Assessment" is defined to mean any levy or charge upon real property for a
special benefit conferred upon the real property.

                 Article XIII D of Proposition 218 also adds several provisions
affecting "fees" and "charges" which are defined as "any levy other than an ad
valorem tax, a special tax, or an assessment, imposed by a local government
upon a parcel or upon a person as an incident of property ownership, including
a user fee or charge for a property related service."  All new and, after June
30, 1997, existing property related fees and charges must conform to
requirements prohibiting, among other things, fees and charges which (i)
generate revenues exceeding the funds required to provide the property related
service, (ii) are used for any purpose other than those for which the fees and
charges are imposed, (iii) are for a service not actually used by, or
immediately available to, the owner of the property in question, or (iv) are
used for general governmental services, including police, fire or library
services, where the service is available to the public at large in
substantially the same manner as it is to property owners.  Further, before any
property related fee or charge may be imposed or increased, written notice must
be given to the record owner of each parcel of land affected by such fee or
charges.  The local government must then hold a hearing upon the proposed
imposition or increase of such property based fee, and if written protests
against the proposal are presented by a majority of the owners of the
identified parcels, the local government may not impose or increase the fee or
charge.  Moreover, except for fees or charges for sewer, water and refuse
collection services, no property related fee or charge may be imposed or
increased without majority approval by the property owners subject to the fee
or charge or, at the option of the local agency, two-thirds voter approval by
the electorate residing in the affected area.

                 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.

         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





                                      -42-
<PAGE>   43

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 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.





                                      -43-
<PAGE>   44
                 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
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





                                      -44-
<PAGE>   45

(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.

         ARIZONA MUNICIPAL INSTRUMENTS

         Under its constitution, the State of Arizona is not permitted to issue
general obligation bonds secured by the full faith and credit of the State.
However, certain agencies and instrumentalities of the State are authorized to
issue bonds secured by revenues from specific projects and activities.  The
State enters into certain lease transactions which are subject to annual
renewal at the option of the State.  Local governmental units in the State are
also authorized to incur indebtedness.  The major source of financing for such
local government indebtedness is an ad valorem property tax.  In addition, in
order to finance public projects, local governments in the State can issue
revenue bonds payable from the revenues of a utility or enterprise or from the
proceeds of an excise tax, or assessment bonds payable from special proceeds of
an excise tax, or assessment bonds payable from special assessments.  Arizona
local governments have also financed public projects through leases which are
subject to annual appropriation at the option of the local government.

         There is a statutory restriction on the amount of annual increases in
taxes that can be levied by the various taxing jurisdictions in the State
without electoral approval.  This restriction does not apply to taxes levied to
pay general obligation debt.

         There are periodic attempts in the form of voter initiatives and
legislative proposals to further limit the amount of annual increases in taxes
that can be levied by the various taxing jurisdictions without voter approval.
It is possible that if such a proposal were enacted, there would be an adverse
impact on State or local government financing.  It is not possible to predict
whether any such proposals will be enacted in the future or what would be their
possible impact on state or local government financing.

         Arizona is required by law to maintain a balanced budget.  To achieve
this objective, the State has, in the past, utilized a combination of spending
reductions and tax increases.  In recent





                                      -45-
<PAGE>   46
years, the State's fiscal situation has improved, even while tax reduction
measures have been enacted each year since 1992.  In 1992, Arizona voters
passed a measure that requires a two-thirds vote of the legislature to increase
state taxes.  Accordingly, it will be more difficult to reverse tax reductions,
which may adversely affect state fund balances and fiscal conditions.

   
         Arizona state government general fund revenue growth for fiscal years
1996, 1997 and 1998 is forecast to increase 4.1%, 3.7% and 3.2%, respectively,
although growth would be projected at 10.9%, 4.8% and 7.6%, respectively, for
the three years but for legislative changes, principally income and property
tax reduction measures as described below.  The 5.5% increase in sales and use
tax revenue adjusted for reductions resulting from legislative changes,
reflects continued strong economic growth in the state.  With revenue growth
outpacing increased expenditures, the state general fund is projected to end
fiscal year 1997 with a total general fund balance of approximately $431
million.  The amount of this balance is approximately 8.9% of total general
fund revenue for fiscal year 1997.  Included in the total balance is a general
fund ending balance of approximately $190 million, and a budget stabilization
("rainy day") fund balance of approximately $241 million.
    

         The fiscal year 1997 budget adopted by the legislature assumed that
the total general fund balance carried forward from fiscal year 1996 would be
drawn down by approximately $157 million during the course of fiscal year 1997.
Based on this assumption and state projections, the total general fund balance
at the end of fiscal year 1997 will be lower than for fiscal year 1996.

         Additionally, the 1995 legislature enacted a $200 million income tax
reduction package, the 1996 legislature enacted a $200 million property tax
reduction package, and the 1997 legislature enacted a $110 million income tax
reduction package.  There may be additional legislative action during 1998 in
the area of tax and school reform, and the 1998 general election ballot may
include one or more questions related to these issues and the state's tax
structure generally.  The outcomes of any legislative actions or ballot
questions may adversely affect state fund balances and fiscal conditions.

         Arizona has a diversified economic base which is not dependent on any
single industry.  Principal economic sectors include services, manufacturing,
mining, tourism, and the military.  Agriculture, which was at one time a major
sector, now plays a much smaller role in the State's economy.  For several
decades, the population of the State has grown at a substantially higher rate
than the population of the United States.  While the State's economy flourished
during the early 80's, a substantial amount of





                                      -46-
<PAGE>   47
overbuilding occurred, adversely affecting Arizona-based financial
institutions, many of which were placed under the control of the Resolution
Trust Corporation.  The spillover effects produced further weakening in the
State's economy.  The Arizona economy has begun to grow again, albeit at a
slower pace than experienced before the real estate collapse.  The Northern
American Free Trade Agreement is generally viewed as beneficial to the State.
However, further proposed reductions in Federal military expenditures may
adversely affect the Arizona economy.

      OTHER INFORMATION ON CALIFORNIA, FLORIDA AND ARIZONA MUNICIPAL INSTRUMENTS

         Northern Trust believes that it is likely that sufficient California,
Florida and Arizona Municipal Instruments and certain specified federal
obligations should be available to satisfy the respective investment
objectives, policies and limitations of the California, Florida Intermediate
Tax-Exempt and the Arizona Tax-Exempt Funds and, with respect to the California
Funds, to enable those Funds to invest at least 50% of their respective 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 a Fund's investment objective, policies and
limitations because of the unavailability of suitable investments, 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





                                      -47-
<PAGE>   48
         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.

                 (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, the Florida Intermediate Tax-Exempt
         Fund, the California Intermediate Tax-Exempt Fund, the Arizona
         Tax-Exempt Fund or the California 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





                                      -48-
<PAGE>   49
         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 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





                                      -49-
<PAGE>   50
         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, the Florida Intermediate Tax-Exempt Fund, the California
         Intermediate Tax-Exempt Fund, the Arizona Tax-Exempt Fund and the
         California 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, Florida Intermediate Tax-Exempt, California Intermediate Tax-Exempt,
Arizona Tax-Exempt and California 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 in the Morgan Stanley Index, 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
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.  





                                      -50-
<PAGE>   51
         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 guarantees acquired by the Money Market Funds must
satisfy special SEC diversification requirements.  In particular, a security
that has an unconditional guarantee (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 Guarantee") 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 Guarantees from the same
person, except that a Fund may invest up to 25% of its total assets in
securities subject to Unconditional Guarantees 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 an Unconditional Guarantee 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. 





                                      -51-
<PAGE>   52
         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.

         Each Investment Restriction which involves a maximum percentage (other
than the restriction set forth above in Investment Restriction (10)) 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 the Fund.  The 1940 Act requires that if the asset coverage for borrowings
at any time falls below the limits described in Investment Restriction (10),
the Fund involved will, within three days thereafter (not including Sundays and
holidays), reduce the amount of its borrowings to an extent that the net asset
coverage of such borrowings shall conform to such limits.  

         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.

* This column presents the same information as the first column because none of
the Trustees served on a board of another mutual fund related to the Trust.

In addition, for the fiscal year ended March 31, 1997, the Trust paid $18,750
to a former Trustee of the Trust.

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, 1997,
Northern Trust Corporation had approximately $23.9 billion in assets and $15.9
billion in deposits.  Northern Trust and its affiliates administered in various
capacities (including as master trustee, investment manager or custodian) $889
billion in assets as of June 30, 1997, including $149 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, 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.  







                                      -55-
<PAGE>   56

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.
         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.

         Supplemental research information so received is in addition to, and
not in lieu of, services required to be performed by Northern Trust and does
not reduce the advisory fees payable to Northern Trust by the Funds.  The
Trustees will periodically review the commissions paid by the Funds to consider
whether the commissions paid over representative periods of time appear to be
reasonable in relation to the benefits inuring to the Funds.  It is possible
that certain of the supplementary research or other services received will
primarily benefit one or more other investment companies or other accounts for
which investment discretion is exercised.  Conversely, a Fund may be the
primary beneficiary of the research or services received as a result of
portfolio transactions effected for such other account or investment company.

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

1.       The Select Equity, International Select Equity, Technology and Stock
         Index Funds commenced operations on April 6, 1994, April 5, 1994,
         April 1, 1996 and October 7, 1996, 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 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 sold, as well as the expenses incurred in the transaction, will be made by
Northern Trust in the manner it considers to be most equitable and consistent
with its fiduciary obligations to the Fund and other 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.

         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











                                      -68-

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
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
















                                      -69-
<PAGE>   70

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 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, 1998, 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 received, after waivers, administrative fees as
follows:

         Northern Funds has also entered into a Distribution Agreement under
which Sunstone Distribution Services, LLC, as agent, sells shares of each Fund
on a continuous basis.  Sunstone Distribution Services, LLC 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 Distribution Services, LLC for such distribution services.  Sunstone
Distribution Services, LLC is an affiliate of Sunstone.  Miriam M. Allison,
Vice President and Treasurer of Northern Funds, and Mary M. Tenwinkel, Vice
President of Northern Funds, have been President and Vice President,
respectively, of Sunstone Distribution Services, LLC since October 1996.

   
         The Administration Agreement and the Distribution Agreement provide
that Sunstone and Sunstone Distribution Services, LLC, respectively, may render
similar services to others so long as their services under the respective
Agreements are not impaired thereby.  The Administration and Distribution
Agreements provide that Northern Funds will indemnify Sunstone and Sunstone
Distribution Services, LLC, respectively, 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 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, 1997, the Municipal Money Market
Fund and the U.S. Government Money Market Fund paid fees of $98 and $59,754
respectively.  No other Funds under the Service Plan paid fees under either
Plan.

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.

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 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 shares at a price which is lower than their purchase
price.  An investor may want to consider his or her 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.



                                       -75-
<PAGE>   76
         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 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, 1997, the 7-day
yields for the Money Market Funds, after fee waivers, were as follows: Money
Market Fund, 5.07%; U.S. Government Money Market Fund, 5.00%; Municipal Money
Market Fund, 3.03%; U.S.



                                       -76-
<PAGE>   77
Government Select Money Market Fund, 5.03%; and California Municipal Money
Market Fund, 3.03%.  For the period ended March 31, 1997, the 7-day yields for
the Money Market Funds, absent fee waivers, were as follows: Money Market Fund,
4.93%; U.S. Government Money Market Fund, 4.81%; Municipal Money Market Fund,
2.90%; U.S. Government Select Money Market Fund, 4.72%; and California
Municipal Money Market Fund, 2.63%.

         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, 1997, the 7-day effective yields for the Money Market Funds, after fee
waivers, were as follows:  Money Market Fund, 5.20%; U.S. Government Money
Market Fund, 5.12%; Municipal Money Market Fund, 3.08%; U.S. Government Select
Money Market Fund, 5.16%; and California Municipal Money Market Fund, 3.08%.

         "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, 1997, and using a federal income tax rate of 31%, the
7-day tax-equivalent yields, after fee waivers, were 4.39% and 4.39% for the
Municipal Money Market and California Municipal Money Market Funds,
respectively.

         A Money Market Fund may also quote, from time to time, total return
information using the formula described in the following section.

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);



                                       -77-
<PAGE>   78
                    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 one year period ended March 31, 1997 and
for the period from the respective dates they commenced operations to March 31,
1997, were as follows:  U.S. Government Fund, 3.98% and 5.02%; Fixed Income
Fund, 4.59% and 6.59%; Intermediate Tax-Exempt Fund, 3.39% and 4.84%;
Tax-Exempt Fund, 4.32% and 5.95%; International Fixed Income Fund, 1.39% and
6.56%; Income Equity Fund, 14.42% and 12.07%; Growth Equity Fund, 11.72% and
14.36%; Select Equity Fund, 15.64% and 16.35%; Small Cap Fund, 12.48% and
11.95%; International Growth Equity Fund, 2.61% and 2.75%; International Select
Equity Fund, -1.95% and 1.95%; and Technology Fund, 20.82% and 20.82%.  The
Short-Intermediate U.S. Government Fund, California Intermediate Tax- Exempt
Fund, Arizona Tax-Exempt Fund, California Tax-Exempt Fund and Small Cap 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 "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:

                                              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, 1997, were as follows:
U.S. Government Fund, 15.85%; Fixed Income Fund, 21.12%; Intermediate
Tax-Exempt Fund, 15.26%; Tax-Exempt Fund, 18.97%; International Fixed Income
Fund, 21.01%; Income Equity Fund, 40.81%; Growth Equity Fund, 49.62%; Select
Equity Fund, 57.25%; Small Cap Fund, 40.36%; International Growth Equity Fund,
8.49%; and International Select Equity Fund, 5.93%.  Based on the foregoing
calculations, the aggregate total return for the Technology Fund for the period
April 1, 1996 (commencement of operations) to



                                       -78-
<PAGE>   79
March 31, 1997 was 20.82%, the aggregate total return for the Florida
Intermediate Tax-Exempt Fund for the period August 15, 1996 (commencement of
operations) to March 31, 1997 was 2.63% and the aggregate total return for the
Stock Index Fund for the period October 7, 1996 (commencement of operations) to
March 31, 1997 was 8.21%.  The Short-Intermediate U.S. Government Fund,
California Intermediate Tax-Exempt Fund, Arizona Tax- Exempt Fund, California
Tax-Exempt Fund and Small Cap 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, 1997, the yields for the U.S Government, Fixed Income, Intermediate
Tax-Exempt, Florida Intermediate Tax-Exempt, Tax-Exempt and International Fixed
Income Funds, after fee waivers, were 5.65%, 5.98%, 3.80%, 4.13%, 4.55% and
4.52%, respectively.  Also for the 30-day period ended March 31, 1997, the
yields for the U.S Government, Fixed Income, Intermediate Tax-Exempt, Florida
Intermediate Tax-Exempt, Tax-Exempt and International Fixed Income Funds,
absent fee waivers, were 5.41%, 5.75%, 3.62%, 3.10%, 4.31% and 2.68%,
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, 1997, and using
a federal income tax rate of 31%, the 30-day tax-equivalent yields, after fee
waivers, were 5.51%, 5.99% and 6.59% for the


                                       -79-
<PAGE>   80
Intermediate Tax-Exempt, Florida Intermediate Tax-Exempt and Tax-Exempt Funds,
respectively.

GENERAL INFORMATION

         The performance information set forth above includes the reinvestment
of dividends and distributions and reflects fee waivers in effect; in the
absence of fee waivers, performance would be reduced.  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 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


                                       -80-
<PAGE>   81
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 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



                                       -81-
<PAGE>   82
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 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



                                       -82-
<PAGE>   83
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
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.



                                       -83-
<PAGE>   84
         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

   
         [Note: The following discussion does not reflect proposed tax changes
that were pending as of the date of this Additional Statement.]
    

         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 "Distribution Requirement") and satisfies certain other
requirements of the Code that are described below.


                                       -84-
<PAGE>   85
         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 year.  A dividend usually will be treated as a
"qualifying dividend" if it has been received from a domestic corporation.  A



                                       -85-
<PAGE>   86
portion of the dividends paid by the Income Equity Fund, Stock Index Fund,
Growth Equity Fund, Select Equity Fund, Small Cap Fund, Technology Fund and
Small Cap Index 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 marginal rate
of 39.6%, but because of limitations on itemized deductions otherwise allowable
and the phase-out of personal exemptions, the maximum effective marginal rate
of tax for some taxpayers may be higher.  An individual's long-term capital
gains are currently taxable at a maximum marginal rate of 28%.  For
corporations, long-term capital gains and ordinary income are both taxable at a
maximum marginal rate of 35% although surtaxes apply to ordinary income at
specified levels.

         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,
Intermediate Tax-Exempt, Florida Intermediate Tax-Exempt, Tax-Exempt, Arizona
Tax-Exempt and California Funds are designed to provide investors with
tax-exempt interest income.  The Funds are 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.



                                       -86-
<PAGE>   87
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, Intermediate Tax-Exempt,
Florida Intermediate Tax-Exempt, Tax-Exempt, Arizona Tax-Exempt or California
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 companies that regularly
distribute at least 90% of its net tax-



                                       -87-
<PAGE>   88
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 sales, wash
sales and loss deferral rules and the requirement to



                                       -88-
<PAGE>   89
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



                                       -89-
<PAGE>   90
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 FUNDS

         Assuming each of the California Funds 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.  Each of the California Funds may be taxed on its
undistributed taxable income.  If for any year one of the California Funds does
not qualify as a regulated investment company, all of that Fund's taxable
income (including



                                       -90-
<PAGE>   91
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, if held by an
individual, is exempt from taxation by California ("California Municipal
Instruments") and (ii) certain U.S. Government and U.S. possession obligations
("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.  Each of the California Funds intends to qualify under the above
requirements so that it can pay California exempt-interest dividends.  If one
of the California Funds fails to so qualify, no part of that Fund's dividends
to shareholders will be exempt from the California state personal income tax.
Each of the California Funds 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, each of the
California Funds 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 one of the
California Funds, 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 the possible
unavailability of federal exempt-interest dividend treatment to



                                       -91-
<PAGE>   92
"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 shares of one of
the California Funds is not deductible for California state personal income tax
purposes if that Fund distributes California exempt-interest dividends during
the shareholder's 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
Funds and their shareholders.  No attempt is made to present a detailed
explanation of the California state personal income tax treatment of the
California Funds or their shareholders, and this discussion is not intended as
a substitute for careful planning.  Further, it should be noted that the
portion of a 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 one of the California Funds, 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



                                       -92-
<PAGE>   93
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.

SPECIAL STATE TAX CONSIDERATIONS PERTAINING TO THE ARIZONA TAX-EXEMPT FUND

         Individuals, trusts and estates who are subject to Arizona income tax
will not be subject to such tax on dividends paid by the Arizona Tax-Exempt
Fund, to the extent that such dividends qualify as exempt-interest dividends of
a regulated investment company under Section 852(b)(5) of the Code and are
attributable to either (i) obligations of the State of Arizona or its political
subdivisions thereof or (ii) obligations issued by the governments



                                       -93-
<PAGE>   94
of Guam, Puerto Rico, or the Virgin Islands.  In addition, dividends paid by
the Arizona Tax-Exempt Fund which are attributable to interest payments on
direct obligations of the United States government will not be subject to
Arizona income tax to the extent the Arizona Tax-Exempt Fund qualifies as a
regulated investment company under Subchapter M of the Code.  Other
distributions from the Arizona Tax-Exempt Fund, however, such as distributions
of short-term or long-term capital gains, will generally not be exempt from
Arizona income tax.

         There are no municipal income taxes in Arizona.  Moreover, because
shares of the Arizona Tax-Exempt Fund are intangibles, they are not subject to
Arizona property tax.  Shareholders of the Arizona Tax-Exempt Fund should
consult their tax advisors about other state and local tax consequences of
their investment in the Arizona Tax-Exempt Fund.


                             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 twenty-four 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 $.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


                                       -94-
<PAGE>   95
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 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



                                       -95-
<PAGE>   96
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 July 17, 1997, 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 60675, 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 July 17, 1997, the names and share ownership of the entities or
individuals which held of record or beneficially more than 5% of the
outstanding shares of any Fund were as follows:  Money Market Fund:  Northern
Trust Bank - Miami on behalf of its customers, 28.14%; U.S. Government Money
Market Fund: Northern Trust Bank - Miami on behalf of its customers, 11.47%,
and Sahara Enterprises, Inc. Fixed Income Portfolio, 9.96%; Municipal Money
Market Fund:  Northern Trust Bank - Miami on behalf of its customers, 24.39%;
U.S. Government Select Money Market Fund:  Frank Hood Trane Revocable Trust,
7.52%, and Northern Trust Bank - Miami on behalf of its customers, 21.74%;
Select Equity Fund:  Donaldson Lufkin & Jenrette Securities Corp., 8.14%;
International Select Equity Fund:  James L. Knight 1969 Trust Sub-Account,
5.70%; Florida Intermediate Tax-Exempt Fund:  Abraham General Partnership,
11.32%, Richard Coren, 5.71%, Donaldson, Lufkin & Jenrette Securities Corp.,
6.97%, and Northern Trust Bank - Miami on behalf of its customers, 5.68%;
California Municipal Money Market Fund:  Lesher-Wells Fargo, 7.96%, Lauralee K.
Bell 1993 Trust, 6.34%, and Northern Trust Bank - M&I Sweep Account, 5.93%;
California Tax-Exempt Fund:  Sheridan Family Trust, 12.03%, and Stephen & Jerri
Harrison Trust, 5.13%; and International Fixed Income Fund:  Jeffrey Hutchens,
6.74%.  The address of all of the above persons is c/o The Northern Trust Bank,
50 S. LaSalle Street, Chicago, Illinois 60675.


   
         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. In addition, the Trustees have adopted a by-law (changeable without
shareholder approval) that provides that a Trustee will cease to serve as a
Trustee effective as of the last calendar day in the semi-annual fiscal period
of Northern Funds in which the earlier of the following events occurs: (a) the
date such Trustee attains the age of seventy-three years; and (b) the twelfth
anniversary of the date of such Trustee's written acceptance to serve as a
Trustee.

    

         Under Massachusetts law, there is a possibility that shareholders of a
business trust could, under certain



                                       -96-
<PAGE>   97
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 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" - The highest category indicates that the degree of
safety regarding timely payment is strong.  Those issues determined to possess
extremely strong safety characteristics are denoted with a plus sign (+)
designation.

                 "A-2" - Capacity for timely payment on issues with this
designation is satisfactory.  However, the relative degree of safety is not as
high as for issues designated "A-1."

                 "A-3" - Issues carrying this designation have adequate
capacity for timely payment.  They are, however, more vulnerable to the adverse
effects of changes in circumstances than obligations carrying the higher
designations.

                 "B" - Issues are regarded as having only a speculative capacity
for timely payment.

                 "C" - This rating is assigned to short-term debt obligations 
with a doubtful capacity for payment.

                 "D" - Issues are in payment default.

                 Moody's commercial paper ratings are opinions of the ability
of issuers to repay punctually senior debt obligations not having an original
maturity in excess of one year, unless explicitly noted.  The following
summarizes the rating categories used by Moody's for commercial paper:

                 "Prime-1" - Issuers or related supporting institutions have a
superior capacity for repayment of senior short-term promissory obligations.
Prime-1 repayment capacity will often be evidenced by the following
characteristics: leading market positions in well-established industries; high
rates of return on funds employed; conservative capitalization structures with
moderate reliance on debt and ample asset protection; broad margins in earning
coverage of fixed financial charges and high internal cash generation; and
well-established access to a range of financial markets and assured sources of
alternate liquidity.




                                      A-1
<PAGE>   100
                 "Prime-2" - Issuers or related supporting institutions have a
strong ability for repayment of senior short-term promissory obligations.  This
will normally be evidenced by many of the characteristics cited above but to a
lesser degree.  Earnings trends and coverage ratios, while sound, may be more
subject to variation.  Capitalization characteristics, while still appropriate,
may be more affected by external conditions.  Ample alternative liquidity is
maintained.

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

                 "Not Prime" - Issuers do not fall within any of the Prime
rating categories.

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

                 "D-1+" - Debt possesses 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




                                      A-2
<PAGE>   101
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.

                 "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"
ratings.
                 "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





                                      A-3
<PAGE>   102
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 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.





                                      A-4
<PAGE>   103
                 "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.

                 "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 and is
currently highly vulnerable to nonpayment.
                 "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





                                      A-5
<PAGE>   104
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 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 are considered as medium-grade obligations,
(i.e., they are neither highly protected nor poorly secured).  Interest
payments and principal security appear adequate for the present but certain
protective elements may be lacking or may be characteristically unreliable over
any great length of time.  Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.




                                      A-6
<PAGE>   105
                 "Ba," "B," "Caa," "Ca," and "C" - Bonds that possess one of
these ratings provide questionable protection of interest and principal ("Ba"
indicates speculative elements; "B" indicates a general lack of characteristics
of desirable investment; "Caa" 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 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.

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





                                      A-7
<PAGE>   106
Although below investment grade, debt rated "BB" is deemed likely to meet
obligations when due.  Debt rated "B" possesses the risk that obligations will
not be met when due.  Debt rated "CCC" is well below investment grade and has
considerable uncertainty as to timely payment of principal, interest or
preferred dividends.  Debt rated "DD" is a defaulted debt obligation, and the
rating "DP" represents preferred stock with dividend arrearages.

                 To provide more detailed indications of credit quality, the
"AA," "A," "BBB," "BB" and "B" ratings may be modified by the addition of a
plus (+) or minus (-) sign to show relative standing within these major
categories.
                 The following summarizes the ratings used by Fitch for
corporate and municipal bonds:
                 "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.
                 "BB" - Bonds considered to be speculative.  The obligor's
ability to pay interest and repay principal may be affected over time by
adverse economic changes.  However, business and financial alternatives can be
identified, which could assist the obligor in satisfying its debt service
requirements.




                                      A-8
<PAGE>   107
                 "B" - Bonds are considered highly speculative.  While
securities in this class are currently meeting debt service requirements, the
probability of continued timely payment of principal and interest reflects the
obligor's limited margin of safety and the need for reasonable business and
economic activity throughout the life of the instrument.

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

                 "CC" - Bonds are minimally protected.  Default in payments of 
interest seems probable over time.

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

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

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


MUNICIPAL NOTE RATINGS

                 A Standard and Poor's rating reflects the liquidity concerns
and market access risks unique to notes due in three years or less.  The
following summarizes the ratings used by Standard & Poor's Ratings Group for
municipal notes:
                 "SP-1" - The issuers of these municipal notes exhibit a strong
capacity to pay principal and interest.  Those issues determined to possess
very strong characteristics are given a plus (+) designation.
                 "SP-2" - The issuers of these municipal notes exhibit
satisfactory capacity to pay principal and interest.

                 "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.

                                   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 three business days after the
trade.  In the futures market, only a contract is made to purchase or sell a
bond in the future for a set price on a certain date.  Historically, the prices
for bonds established in the futures markets have tended to move generally in
the aggregate in concert with the cash market prices and have maintained fairly
predictable relationships.  Accordingly, a Fund may use interest rate futures
contracts as a defense, or hedge, against anticipated interest rate changes.
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 a Fund, by using
futures contracts.

                 Interest rate future contracts can also be used by a Fund for
non-hedging (speculative) purposes to increase total return.
                 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





                                      B-1
<PAGE>   110
the rules of the exchange on which the futures contract sale or purchase was
made.
                 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's entering into a futures contract purchase for the same aggregate amount
of the specific type of financial instrument and the same delivery date.  If
the price of 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.  To the extent consistent with its




                                      B-2
<PAGE>   111
investment objective, a Fund may also engage 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).
                 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.
                 Index futures contracts may also be used by a Fund for
non-hedging (speculative) purposes to increase total return.
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 purchases 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 or sub-custodian an amount of liquid
assets, known as initial margin, based on the value of the contract.  The
nature of initial margin in futures transactions is different from that of
margin in security transactions in that futures contract margin does not
involve the borrowing of funds by the customer to finance the




                                      B-3
<PAGE>   112
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 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.  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





                                      B-4
<PAGE>   113
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
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





                                      B-5
<PAGE>   114
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 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,





                                      B-6
<PAGE>   115
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 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.
