PROSPECTUS DATED JUNE 1, 1997                             


IAI  Developing   Countries   Fund   ("Developing   Countries   Fund")  and  IAI
International  Fund  ("International  Fund")  are  separate  portfolios  of  IAI
Investment  Funds III,  Inc.,  an  open-end  diversified  management  investment
company authorized to issue its shares of common stock in more than one series.

Developing  Countries  Fund seeks to achieve its objective of long-term  capital
appreciation by investing  primarily in equity securities of companies domiciled
or otherwise having substantial operations in developing countries. There can be
no assurance  that  Developing  Countries  Fund's  investment  objective will be
achieved.

International  Fund's primary  objective is capital  appreciation,  with current
income (principally from dividends) being the secondary objective. International
Fund will  endeavor  to  achieve  its  objectives  by  investing,  under  normal
circumstances,  at least  95% of its  portfolio  in  equity  and  equity-related
securities of non-United States issuers.

Investing  in  Developing   Countries  Fund  or   International   Fund  involves
significant risks and considerations  not normally  associated with a fund which
invests   primarily  in  securities  of  U.S.  issuers  and  may  be  considered
speculative.  Shares of either Developing  Countries Fund or International  Fund
are not designed to be a complete investment program. See "Fund Risk Factors" on
page 13.


This  Prospectus  sets  forth  concisely  the  information  which a  prospective
investor should know about each Fund before  investing and it should be retained
for future reference. A "Statement of Additional Information" dated June 1, 1997
which  provides a further  discussion  of certain areas in this  Prospectus  and
other  matters which may be of interest to some  investors,  has been filed with
the Securities and Exchange  Commission and is incorporated herein by reference.
For a free  copy,  call or write the Funds at the  address or  telephone  number
shown on the inside back cover of this Prospectus.


THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE  COMMISSION OR ANY STATE  SECURITIES  COMMISSION NOR HAS THE SECURITIES
AND  EXCHANGE  COMMISSION  OR ANY STATE  SECURITIES  COMMISSION  PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

</TABLE>

The  purpose of the above  table is to assist you in  understanding  the various
costs  and  expenses  that an  investor  in the  Funds  will  bear  directly  or
indirectly.  Because of a change in each  Fund's fee  structure  during the last
fiscal  year,  the  information  in the table has been  restated to reflect each
Fund's current fees. The information with respect to International Fund reflects
a fee break based on the Fund's  size.  The example  should not be  considered a
representation  of past or future  expenses.  Actual  expenses may be greater or
less than those shown.

     ** The Fund's  adviser  voluntarily  waived $17,765 and $45,293 in expenses
for the year ended  January 31,  1997 and the period  ended  January  31,  1996,
respectively. If the Fund had been charged these expenses, the ratio of expenses
to average daily net assets would have been 2.17% and 3.42%,  respectively,  and
the ratio of net investment income (loss) to average daily net assets would have
been 0.35% and  (1.23%),  respectively.  For the fiscal  year ended  January 31,
1996, the ratio of expenses to average daily net assets  includes  expenses paid
indirectly by the Fund.

     *** Commencement of operations.

     ****  Beginning in fiscal 1997, the Fund is required to disclose an average
brokerage  commission  rate.  The  comparability  of rates between  domestic and
foreign equities may be affected by the fact that commission rates per share can
vary significantly among foreign countries.

INVESTMENT OBJECTIVES 
AND POLICIES

DEVELOPING COUNTRIES 
FUND

The investment  objective of Developing  Countries Fund is to provide  long-term
capital  appreciation.  The Fund seeks to achieve  its  objective  by  investing
primarily  in equity  securities  of companies  domiciled  or  otherwise  having
substantial  operations  in  developing  countries.  Such  objective  may not be
changed without shareholder approval.  There can be no assurance that Developing
Countries Fund will achieve its investment objective.

Under  normal  conditions,  at least 65% of  Developing  Countries  Fund's total
assets will be invested in securities of companies domiciled or otherwise having
substantial  operations in developing  countries.  Developing  countries include
those generally considered to be developing or emerging by the World Bank or the
International  Finance Corporation,  as well as countries that are classified by
the United  Nations or otherwise  regarded by their  authorities  as developing.
Countries presently not considered developing are: Australia,  Austria, Belgium,
Canada,  Denmark,   Finland,   France,  Germany,   Ireland,  Italy,  Japan,  the
Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland, the United Kingdom
and the United States.  Developing  Countries Fund may also invest in securities
of companies that derive 50% or more of their total revenue from either goods or
services  produced  in  developing  countries  or sales made in such  developing
countries and companies  that maintain 50% or more of their assets in developing
countries.  Determinations as to eligibility will be based on publicly available
information and inquiries made to the companies.

Developing Countries Fund will not necessarily seek to diversify  investments on
a geographic  basis or on the basis of the level of economic  development of any
particular  country.  Developing  Countries  Fund focuses on equity  securities,
however,  it may also  invest  in  other  types of  instruments  including  debt
securities. Developing Countries Fund has established no minimum rating criteria
for the debt  securities in which it may invest,  and such securities may not be
rated  at all for  creditworthiness.  Securities  rated in the  medium  to lower
rating categories of nationally recognized  statistical rating organizations and
unrated  securities of comparable  quality are  predominantly  speculative  with
respect to the capacity to pay interest and repay  principal in accordance  with
the terms of the security and  generally  involve a greater  volatility of price
than  securities  in higher  rating  categories.  Such  securities  are commonly
referred to as junk bonds.  Developing  Countries Fund does not currently intend
to  invest  more  than  5% of its net  assets  in junk  bonds.  See  "Investment
Objective  and  Policies"  in  the  Statement  of  Additional   Information  for
additional information regarding ratings of debt securities.  In purchasing such
securities,  the Fund will rely on IAI's  judgment,  analysis and  experience in
evaluating the  creditworthiness of an issuer of such securities.  IAI will take
into consideration,  among other things, the issuer's financial  resources,  its
sensitivity  to economic  conditions  and trends,  its  operating  history,  the
quality of

the issuer's  management  and  regulatory  matters.  The Fund does not intend to
purchase  debt  securities  that are in default or which IAI believes will be in
default.

Developing Countries Fund can use various techniques to increase or decrease its
exposure to changing security prices,  interest rates,  currency exchange rates,
commodity prices, or other factors that affect security values. These techniques
include buying and selling options and futures contracts, entering into currency
exchange  contracts  or swap  agreements,  purchasing  indexed  securities,  and
selling  securities  short.  Further  information  regarding such  techniques is
contained in the Statement of Additional Information.

INTERNATIONAL FUND

The primary investment  objective of International Fund is capital  appreciation
with current income  (principally  from dividends) being a secondary  objective.
International   Fund  pursues  its   objectives  by   investing,   under  normal
circumstances,  at  least  95% of the  value of its net  assets  in  equity  and
equity-related  securities of non-United States issuers. Such objectives may not
be  changed  without  shareholder  approval.  There  can  be no  assurance  that
International Fund will achieve its investment objectives.

International  Fund  invests  primarily  in  equity  securities  which  have the
potential for  above-average  capital  appreciation.  Equity securities in which
International  Fund will invest include,  but are not limited to, common stocks,
securities convertible into common stock, preferred stock, partnership interests
and other equity participations.  From time to time, International Fund may also
invest up to 20% of its net asets in the  securities  of  companies  with market
capitalizations less than $1 billion.

When the anticipated total return from debt securities significantly exceeds the
anticipated  total  return  from  foreign  equity  securities,   up  to  50%  of
International Fund's portfolio may be comprised of cash, cash equivalents, bonds
and other debt securities of both United States and foreign issuers including:

     (a) Bonds and other fixed income  securities of United States issuers which
are rated  within  the four  highest  grades  ("investment  grade")  by  Moody's
Investors Service, Inc. ("Moody's") or Standard & Poor's Corporation ("S&P").

     (b) Corporate notes,  bonds and other debt securities (such as Eurocurrency
instruments) of non-United  States issuers judged by IAI as being  equivalent in
repayment  security to investment grade domestic  obligations,  provided that no
more than 35% of  International  Fund's  portfolio  will be  invested in foreign
corporate debt  securities  with maturities of greater than one year at the time
of investment.

     (c) United States dollars or securities with maturities of one year or less
of,  or  guaranteed  by,  the  United  States   Government,   its  agencies  and
instrumentalities.


                                                                             -7-

                                IAI MUTUAL FUNDS
             IAI DEVELOPING COUNTRIES FUND, IAI INTERNATIONAL FUND



     (d)  Foreign  currencies  or  securities  of,  or  guaranteed  by,  foreign
governments  or the agencies or  instrumentalities  of foreign  governments,  or
securities  issued by  supranational  agencies (such as the World Bank) that are
equivalent  in repayment  security to  investment  grade  domestic  obligations,
provided  that  not more  than 35% of  International  Fund's  portfolio  will be
invested in foreign government obligations having a maturity of greater than one
year from the date of investment.

     (e) Short-term  debt  instruments  of domestic and foreign  issuers such as
commercial  paper,  bank  certificates  of deposit,  bankers'  acceptances,  and
repurchase agreements for such securities (provided that International Fund will
not invest in foreign  repurchase  agreements and provided further that the Fund
may not  invest  more  than  10% of its  total  assets  in  domestic  repurchase
agreements and may invest in such repurchase  agreements for defensive  purposes
only).  The  commercial  paper  purchased  by the Fund will  consist only of (i)
obligations  rated either  Prime-2 or better by Moody's or A-2 or better by S&P,
or (ii) unrated or foreign obligations issued by companies  considered by IAI to
offer equivalent repayment security.

International  Fund is not required to maintain any particular  geographical  or
currency  mix  of  its   investments.   Therefore,   at  any  particular   time,
International  Fund's  investment  portfolio may be  substantially  or primarily
invested in securities of one or more selected markets where it appears that the
available  return  from  investments  in such  markets  will equal or exceed the
return available from  investments in securities of other markets.  Under normal
circumstances,  however,  International  Fund  currently  intends  to  invest  a
significant portion of its assets in countries that generally are representative
of the market  capitalization of the securities of the countries  comprising the
Morgan Stanley Capital International Europe, Australia, Far East ("EAFE") Index,
an unmanaged index of foreign common stocks.  The following table sets forth the
approximate   weighting   of  the  EAFE  Index   based  upon   relative   market
capitalizations  of  securities  in  countries  comprising  the EAFE Index as of
January 31, 1997, as well as the composition of  International  Fund's portfolio
as of the same date:

In making the  allocation  of assets among the various  markets  throughout  the
world,  International  Fund  considers  such factors as  prospects  for relative
economic  growth between  foreign  countries,  expected  levels of inflation and
interest rates,  government policies influencing business conditions,  the range
of individual investment opportunities available to international investors, and
other pertinent financial,  tax, social,  political and national factors, all in
relation  to the  prevailing  prices of  securities  in each  country or region.
Nearly all foreign  securities in which  International  Fund will invest will be
issued by foreign corporations or traded on foreign stock exchanges.

International  Fund may from  time to time  invest  more  than 50% of its  total
assets in Japan,  although not less than four different  foreign economies will,
under normal  circumstances,  at any time be represented in International Fund's
portfolio.  Other economies in which management  anticipates that  International
Fund may from time to time concentrate more than 25% of its total assets include
the United Kingdom and Germany.
    
As discussed  above,  International  Fund may from time to time concentrate more
than 25% of its total  assets in the  economy of Japan.  The  following  section
includes a general  discussion  of the economy of Japan.  Although  the Fund may
concentrate  more  than 25% of its  assets  in the  United  Kingdom  and  German
economies, it does not expect to do so in the upcoming fiscal year. A discussion
of the economies of the United Kingdom and Germany is set forth in the Statement
of Additional Information.


                                                                             -9-

Reporting,  accounting and auditing  standards in Japan,  the United Kingdom and
Germany differ from American  standards in important  respects.  Corporations in
such countries generally do not provide all of the disclosures  required by U.S.
law and  accounting  practice,  and  such  disclosure  may be less  timely  than
required by such laws and practices.

Japan is politically organized as a democratic, parliamentary republic and has a
population  of  approximately  122  million.  The  Japanese  economy  is heavily
industrial  and  export-oriented.  Although  Japan  is  dependent  upon  foreign
economies  for raw  materials,  Japan's  balance of payments in recent years has
been strong and positive.

Japan has eight stock exchanges located throughout the country,  but over 80% of
all trading is conducted on the Tokyo Stock Exchange.

Prices of stocks listed on the Japanese stock  exchange are quoted  continuously
during regular  business  hours.  Trading  commissions  are at fixed scale rates
which vary by the type and the value of the  transaction,  but can be negotiable
for large transactions.

Securities in Japan are denominated and quoted in yen. Yen are fully convertible
and transferable  based on floating exchange rates into all currencies,  without
administrative  or legal  restrictions,  for both  nonresidents and residents of
Japan.

International  Fund may also invest in developing  countries,  which investments
involve  exposure to economic  structures  that are  generally  less diverse and
mature than in the United  States,  and to political  systems  which may be less
stable.  As  stated in the  "Investment  Objective  and  Policies"  section  for
Developing   Countries  Fund,   developing  countries  include  those  generally
considered to be  developing or emerging by the World Bank or the  International
Finance  Corporation,  as well as countries  that are  classified  by the United
Nations or otherwise  regarded by their authorities as developing.  In the past,
markets of  developing  countries  have been more  volatile  than the markets of
developed countries.  Such markets,  however, often have provided investors with
higher  returns  on  their  investments.   International  Fund  will  limit  its
investments  in developing  countries not included in the EAFE Index to not more
than 15% of its total  assets.  For  purposes of  determining  the country of an
issuer for percentage limitation purposes, the Fund considers where an issuer is
domiciled or otherwise has substantial operations.

OTHER FUND INVESTMENT 
TECHNIQUES

The  ability  of the  Funds to  utilize  certain  of the  investment  techniques
discussed  below may be  subject to  limitations  and may  subject  the Funds to
additional  risks.  Please refer to the section "Fund Risk Factors" below and to
the Statement of Additional  Information  for more  information  regarding  such
limitations and risks.  Unless otherwise indicated herein or in the Statement of
Additional  Information,  each Fund may  invest up to 100% of its  assets in the
securities listed below.

DEPOSITARY RECEIPTS

In addition to investing in such  securities  directly,  each Fund may invest in
the  securities  of foreign  issuers in the form of  sponsored  and  unsponsored
American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), Global
Depositary  Receipts (GDRs) or other  securities  convertible into securities of
foreign issuers.  Generally,  such securities  evidence  ownership of and may be
converted into securities issued by a

foreign  corporation.  The issuers of  unsponsored  depository  receipts are not
obligated to disclose material  information in the United States, and therefore,
there may not be a correlation  between such information and the market value of
such securities.

FOREIGN INDEX LINKED 
INSTRUMENTS

Each Fund may invest in instruments  issued by the U.S. or a foreign  government
or by private issuers that return  principal and/or pay interest to investors in
amounts which are linked to the level of a particular  foreign  index  ("Foreign
Index Linked  Instruments").  Foreign Index Linked  Instruments may offer higher
yields than comparable securities linked to purely domestic indexes but also may
be more  volatile.  Foreign  Index  Linked  Instruments  are  relatively  recent
innovations  for  which  the  market  has  not yet  been  fully  developed  and,
accordingly, they typically are less liquid than comparable securities linked to
purely  domestic  indexes.  In  addition,  the  value of  Foreign  Index  Linked
Instruments  will be affected by  fluctuations  in foreign  exchange rates or in
foreign  interest  rates.  Foreign  currency  gains and losses  with  respect to
Foreign  Index  Linked  Instruments  may  affect the amount and timing of income
recognized by such Fund.

BRADY BONDS

Each Fund may  invest in Brady  Bonds and other  sovereign  debt  securities  of
countries  that  have  restructured  or  are  in the  process  of  restructuring
sovereign  debt  pursuant  to the Brady Plan.  Brady  Bonds are debt  securities
issued under the framework of the Brady Plan, a mechanism for debtor  nations to
restructure  their  outstanding  external  indebtedness.  Brady  Bonds have been
issued only recently and, accordingly, do not have a long payment history.
                                      
ZERO COUPON SECURITIES

Each Fund may also invest in zero coupon  obligations of the U.S.  Government or
its agencies,  tax exempt  issuers and corporate  issuers,  including  rights to
stripped coupon and principal payments ("STRIPS"). Zero coupon bonds do not make
regular interest payments;  rather, they are sold at a discount from face value.
Principal and accreted discount (representing interest accrued but not paid) are
paid at maturity. STRIPS are debt securities that are stripped of their interest
after the  securities  are issued,  but otherwise are  comparable to zero coupon
bonds. The market values of STRIPS and zero coupon bonds generally  fluctuate in
response   to  changes  in   interest   rates  to  a  greater   degree  than  do
interest-paying securities of comparable term and quality.

ILLIQUID SECURITIES

The Developing  Countries Fund may invest up to 10% of its net assets, while the
International  Fund may invest up to 15% of its net assets,  in securities  that
are considered  illiquid because of the absence of a readily available market or
due to legal or contractual restrictions. However, certain restricted securities
that are not registered for sale to the general public but that can be resold to
institutional  investors may be considered liquid pursuant to guidelines adopted
by the Board of Directors.  The institutional  trading market 

                                                                            -11-

if trading does not develop or declines.

The value of the  assets of a Fund as  measured  in United  States  dollars or a
foreign  currency or  currencies  may be affected  favorably or  unfavorably  by
changes in foreign currency exchange rates and exchange control regulations, and
each  Fund may  incur  costs in  connection  with  conversions  between  various
currencies.  Each Fund will conduct its foreign currency  exchange  transactions
either on a spot (i.e.,  cash) basis at the spot rate  prevailing in the foreign
currency  exchange  market,  or through  forward  contracts  to purchase or sell
foreign  currencies.  A forward foreign currency  exchange  contract involves an
obligation to purchase or sell a specific  currency at a future date,  which may
be any fixed  number of days from the date of the  contract  agreed  upon by the
parties, at a price set at the time of the contract.  These contracts are traded
directly between  currency  traders  (usually large commercial  banks) and their
customers.

Each Fund may enter into foreign currency transactions for hedging purposes only
and may not speculate on the  fluctuations of foreign  currency  exchange rates.
Each Fund may hedge against adverse changes in foreign  currency  exchange rates
between the trade and settlement dates with respect to foreign  securities it is
purchasing  or during the holding  period with respect to foreign  securities in
its portfolio.  With respect to foreign  securities in its portfolio,  each Fund
may  hedge  a  maximum  of 50% of the  value  of  its  investment  portfolio  by
establishing the value of such securities in U.S.  dollars.  Additionally,  each
Fund may hedge a  maximum  of 25% of the value of its  investment  portfolio  by
establishing  the  value of such  securities  in  another  foreign  currency  or
currencies  which IAI  believes to be more stable than the  currencies  in which
such securities are denominated.

When a Fund  enters  into a  contract  for the  purchase  or sale of a  security
denominated  in a  foreign  currency,  it may  desire to  establish  the cost or
proceeds in U.S. dollars or another foreign currency. By entering into a forward
contract  in such  currency  for the  purchase  or sale of the amount of foreign
currency  involved in an  underlying  security  investment,  the Fund is able to
protect itself  against a possible loss between trade and settlement  dates of a
transaction  or  during  the  period  of an  investment  in a  foreign  security
resulting  from  an  adverse  change  in  the  relationship   between  such  two
currencies. However, this tends to limit potential gains which might result from
a  positive  change in such  currency  relationships.  A Fund may also hedge its
foreign currency  exchange rate risk by engaging in currency  financial  futures
and options and forward foreign currency transactions.

When IAI believes that the currency of a particular foreign country may suffer a
substantial decline against the U.S. dollar or another foreign currency,  it may
enter  into  a  forward   contract  to  sell  an  amount  of  foreign   currency
approximating  the  value  of  some  or all  of a  Fund's  portfolio  securities
denominated in such foreign  currency.  The  forecasting of short-term  currency

              IAI DEVELOPING COUNTRIES FUND, IAI INTERNTIONAL FUND


market  movement is  difficult  and the  successful  execution  of a  short-term
hedging strategy is uncertain.

It is  impossible  to  forecast  with  absolute  precision  the market  value of
portfolio  securities at the  expiration of a contract.  Accordingly,  it may be
necessary  for a Fund to  purchase  additional  currency on the spot market (and
bear the expense of such  purchase)  if the market value of the security is less
than the amount of foreign  currency  the Fund is  obligated  to deliver  when a
decision is made to sell the security and make delivery of the foreign  currency
in settlement of a forward contract.  Conversely, it may be necessary to sell on
the spot  market  some of the  foreign  currency  received  upon the sale of the
portfolio  security if its market value  exceeds the amount of foreign  currency
the Fund is obligated to deliver.

If  a  Fund  retains  the  portfolio  security  and  engages  in  an  offsetting
transaction,  the Fund will incur a gain or a loss (as  described  below) to the
extent  that there has been  movement  in  forward  contract  prices.  If a Fund
engages  in an  offsetting  transaction,  it may  subsequently  enter into a new
forward  contract to sell the foreign  currency.  Should  forward prices decline
during the period  between the Fund's  entering into a forward  contract for the
sale of foreign currency and the date it enters into an offsetting  contract for
the  purchase  of the  foreign  currency,  the Fund would  realize a gain to the
extent the price of the  currency it has agreed to sell exceeds the price of the
currency it has agreed to purchase.  Should  forward prices  increase,  the Fund
would  suffer a loss to the  extent the price of the  currency  it has agreed to
purchase exceeds the price of the currency it has agreed to sell.  Although such
contracts tend to minimize the risk of loss due to a decline in the value of the
hedged  currency,  they also tend to limit any potential gain which might result
should the value of such  currency  increase.  A Fund will have to  convert  its
holdings of foreign  currencies  into U.S.  dollars from time to time.  Although
foreign exchange  dealers do not charge a fee for conversion,  they do realize a
profit based on the difference  (the "spread")  between the prices at which they
are buying and selling various currencies.

ADJUSTING INVESTMENT EXPOSURE

Each  Fund  may,  but is not  required  to,  utilize  various  other  investment
strategies as described  below to hedge  various  market risks (such as interest
rates,  currency  exchange  rates,  and broad or  specific  fixed-income  market
movements),  to manage the effective  maturity or duration of a Fund's portfolio
or to enhance  potential gain.  These strategies may be executed through the use
of derivative  contracts.  Such  strategies are generally  accepted as a part of
modern portfolio  management and are regularly utilized by many mutual funds and
other institutional  investors.  Techniques and instruments may change over time
as new instruments and strategies are developed or regulatory changes occur.

In the course of pursuing these investment  strategies,  a Fund may purchase and
sell  exchange-listed and  over-the-counter  put and call options on securities,
fixed-income  indices  and  other  financial  instruments,   

                                                                            -13-
<PAGE>
                                IAI MUTUAL FUNDS
             IAI DEVELOPING COUNTRIES FUND, IAI INTERNATIONAL FUND



purchase and sell financial  futures  contracts and options thereon,  enter into
various interest rate transactions such as swaps and enter into various currency
transactions  such as currency forward  contracts,  currency futures  contracts,
currency swaps or options on currencies or currency futures.

Such  techniques and instruments may be used without limit to attempt to protect
against  possible  changes in the market  value of  securities  held in or to be
purchased for a Fund's portfolio  resulting from securities  markets or currency
exchange rate fluctuations, to protect a Fund's unrealized gains in the value of
its  portfolio  securities,  to  facilitate  the  sale  of such  securities  for
investment  purposes,  to manage the effective  maturity or duration of a Fund's
portfolio,  or to establish a position in the derivatives markets as a temporary
substitute for  purchasing or selling  particular  securities.  Some may also be
used to enhance  potential gain although no more than 5% of a Fund's assets will
be  committed  to  techniques  and  instruments  entered  into  for  non-hedging
purposes.  Any or all of these investment techniques may be used at any time and
in any combination, and there is no particular strategy that dictates the use of
one technique  rather than another,  as use of any technique or instruments is a
function of numerous  variables  including market  conditions.  The ability of a
Fund to utilize these  techniques and  instruments  successfully  will depend on
IAI's ability to predict  pertinent market  movements,  which cannot be assured.
Each Fund will comply with applicable regulatory  requirements when implementing
these  strategies,  techniques and instruments.  Such techniques and instruments
involving  financial  futures and options  thereon  will be  purchased,  sold or
entered into only for bona fide hedging, risk management or portfolio management
purposes and not for speculative purposes.


TEMPORARY INVESTMENTS

Each Fund reserves the right, as a temporary  defensive measure,  such as during
periods of adverse  market  conditions  or when  equity or debt  securities  are
deemed  overvalued,  to  hold up to 100%  of its  total  assets  in cash or cash
equivalents (in U.S. dollars or foreign  currencies) and short-term  securities,
including money market securities.

BORROWING

Each Fund may borrow from banks (or through reverse  repurchase  agreements) for
temporary or emergency purposes. If a Fund borrows money, its share price may be
subject to greater  fluctuation until the borrowing is paid off. If a Fund makes
additional investments while borrowings are outstanding,  this may be considered
a form of leverage.  Each Fund does not intend borrowing to exceed 5% of its net
assets.

CLOSED-END INVESTMENT 
COMPANIES

A number of countries  have  authorized  the formation of closed-end  investment
companies to facilitate  indirect  foreign  investment in their capital markets.
Each Fund may invest up to 10% of its total assets in  securities  of closed-end
investment  companies.  Shares of certain closed-end investment companies may at
times be acquired only at market prices representing premiums to their net asset
values. 

                                      -14-

                                IAI MUTUAL FUNDS
             IAI DEVELOPING COUNTRIES FUND, IAI INTERNATIONAL FUND

In the event that  shares  acquired at a premium  subsequently  decline in price
relative to their net asset value or the value of portfolio  investments held by
such closed-end companies declines, a Fund and its shareholders may experience a
loss.  If a Fund  acquires  shares  of  closed-end  investment  companies,  Fund
shareholders would bear both their  proportionate share of expenses in such Fund
(including  management and advisory fees) and, indirectly,  the expenses of such
closed-end investment companies.

PORTFOLIO TURNOVER

The Funds will dispose of securities  without  regard to the time they have been
held when such action  appears  advisable  to  management  either as a result of
securities  having reached a price  objective,  or by reason of developments not
foreseen  at the  time of the  investment  decision.  Since  investment  changes
usually will be made without reference to the length of time a security has been
held, a significant number of short-term transactions may result. Accordingly, a
Fund's  annual  portfolio  turnover  rate  cannot  be  anticipated  and  may  be
relatively high. High turnover rates (100% or more) increase  transaction  costs
and may increase taxable capital gains. The Funds' historical portfolio turnover
rates are set forth in the section "Financial Highlights."

Further  information  regarding  these and other  techniques is contained in the
Statement of Additional Information.

FUND RISK FACTORS

FOREIGN INVESTMENT RISK 
FACTORS

Developing Countries Fund is designed for aggressive investors interested in the
investment  opportunities  offered in developing  countries.  To the extent that
International Fund invests in developing  countries,  the Fund may be subject to
additional  risk.  While IAI believes  that  investing in  developing  countries
presents the  possibility  for  significant  growth over the long-term,  it also
entails  significant  risks.  Many  investments  in developing  countries can be
considered speculative,  and the price of securities and value of currencies can
be much  more  volatile  than in the more  developed  markets.  This  difference
reflects the greater  uncertainties of investing in less established markets and
economies.

Investing  in  foreign  securities  typically  involves  additional  risks  than
investing in securities of U.S.  issuers.  These risks are often  heightened for
investments  in developing  countries  and include,  but are not limited to, the
risk  of  fluctuations  in the  value  of  the  currencies  in  which  they  are
denominated,  including the  devaluation  of the  currencies  of such  countries
relative  to the  U.S.  dollar,  the  risk of  adverse  political  and  economic
developments   and  the  possibility  of   expropriation,   nationalization   or
confiscatory  taxation or limitations on the removal of funds or other assets of
the Funds. Additionally,  the economies of many developing countries continue to
experience  significant problems,  including 

                                                                            -15-

high inflation  rates,  high interest rates,  large external debt and continuing
trade deficits and are characterized by extreme poverty, high unemployment and a
significant  dependence on limited industries.  Because the Funds will invest in
securities  denominated  or quoted in  currencies  other  than the U.S.  dollar,
changes in foreign currency exchange rates may affect the value of securities in
the  portfolio.  Foreign  currency  exchange  rates are  determined by forces of
supply  and  demand in the  foreign  exchange  markets  and other  economic  and
financial  conditions affecting the world economy. A decline in the value of any
particular  currency  against  the U.S.  dollar will cause a decline in the U.S.
dollar value of a Fund's  holdings of  securities  denominated  in such currency
and,  therefore,  will cause an overall  decline in a Fund's net asset value and
net  investment  income and capital  gains,  if any, to be  distributed  in U.S.
dollars to  shareholders by such Fund. In many  developing  countries,  there is
less government  supervision and regulation of business and industry  practices,
stock  exchanges,  brokers and listed  companies than in the United  States.  In
addition,  there also may be less publicly  available  information about foreign
issuers than domestic issuers,  and foreign issuers generally are not subject to
the uniform accounting,  auditing and financial reporting  standards,  practices
and requirements  applicable to domestic issuers. The foreign securities markets
of many of the countries in which the Funds may invest may also be smaller, less
liquid and subject to greater price  volatility than those in the United States.
As an open-end investment  company,  each Fund is limited in the extent to which
it  may  invest  in  illiquid  securities.  Further,  the  Funds  may  encounter
difficulties  or be unable to pursue  legal  remedies  and obtain  judgments  in
foreign courts. These factors could make foreign  investments,  especially those
in developing countries, more volatile.

Brokerage   commissions,   custodial  services,  and  other  costs  relating  to
investment  in foreign  countries  and  developing  markets are  generally  more
expensive than in the United States.  Such markets have different  clearance and
settlement  procedures  and in  certain  markets  there  have  been  times  when
settlements  have  been  unable  to keep  pace  with the  volume  of  securities
transactions, making it difficult to conduct such transactions. The inability of
a Fund to make intended  security  purchases due to  settlement  problems  could
cause  such  Fund to miss  attractive  investment  opportunities.  Inability  to
dispose of a portfolio  security due to settlement  problems could result either
in  losses  to a Fund due to  subsequent  declines  in  value  of the  portfolio
security or, if a Fund has entered into a contract to sell the  security,  could
result in possible liability to the purchaser.

Several countries  restrict,  to varying degrees,  foreign  investments in their
securities markets. Government and private restrictions take a variety of forms,
including (a)  limitations on the amount of funds that may be introduced into or
repatriated  from  the  country   (including   limitations  on  repatriation  of
investment   income  and  capital  gains);   (b)   prohibitions  or  substantial
restrictions on foreign investment in certain industries or market sectors, such
as defense,  energy and transportation;  (c) restrictions

(whether  contained in the charter of an  individual  company or mandated by the
government)  on the  percentage  of  securities  of a single issuer which may be
owned by a foreign investor;  (d) limitations on the types of securities which a
foreign  investor may purchase;  and (e)  restrictions  on a foreign  investor's
right to invest in companies whose securities are not publicly  traded.  In some
circumstances,  these  restrictions may limit or preclude  investment in certain
countries or may increase the cost of  investing  in  securities  of  particular
companies.

A Fund's  interest  and dividend  income from foreign  issuers may be subject to
non-U.S.  withholding  taxes.  A Fund also may be  subject  to taxes on  trading
profits or on transfers of securities in some countries. The imposition of these
taxes will increase the cost to a Fund of investing in any country imposing such
taxes. For U.S. tax purposes,  U.S.  shareholders may be entitled to a credit or
deduction  to the extent of any  foreign  income  taxes  paid by such Fund.  See
"Dividends, Distributions and Tax Status."

Each Fund may  purchase  sovereign  debt  instruments  issued or  guaranteed  by
foreign  governments  or their  agencies.  Sovereign  debt may be in the form of
conventional securities or other types of debt instruments such as loans or loan
participations. The sovereign debt in which a Fund may invest may involve a high
degree of risk, including the risk of default. Governmental entities responsible
for  repayment  of the debt may be unable or unwilling  to repay  principal  and
interest  when due,  and may  require  renegotiations  or  rescheduling  of debt
payments.  In addition,  prospects  for  repayment of principal and interest may
depend  on  political  as well as  economic  factors.  A Fund may  have  limited
recourse in the event of default on a sovereign debt instrument.

Many  of  the  currencies  of  developing   countries  have  experienced  steady
devaluations   relative  to  the  U.S.  dollar,   and  major  devaluations  have
historically  occurred in certain  countries.  Devaluations in the currencies in
which a Fund's  portfolio  securities  are  denominated  may have a  detrimental
impact on such Fund. Some developing  countries also may have managed currencies
which are not free floating  against the U.S.  dollar.  In addition,  there is a
risk that certain developing countries may restrict the free conversion of their
currencies into other currencies.  Further, the currencies of certain developing
countries may not be internally traded.

Many  developing  countries have  experienced  substantial,  and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations  in inflation rates have had and may continue to have very negative
effects on the economies and securities markets of certain developing countries.
The  governments  of many  developing  countries  have exercised and continue to
exercise  a  significant  influence  over many  aspects of the  private  sector.
Government  actions  concerning  the economy could have a significant  effect on
market  conditions  and  prices  and/or  yields  of  securities  in which a Fund
invests.

In some countries,  the securities of banks or other financial  institutions are
among  the most  actively  traded  securities.  Each 

                                                                            -17-

Fund is restricted in its ability to invest in securities of an issuer which, in
its most recent year,  derived more than 15% of its  revenues  from  "securities
related activities," as defined by the rules under the Investment Company Act of
1940.
                                      
RISKS ASSOCIATED WITH 
ADJUSTING INVESTMENT 
EXPOSURE

The techniques and instruments  described in the section  "Adjusting  Investment
Exposure",  including  derivative  contracts,  have risks  associated  with them
including  possible default by the other party to the  transaction,  illiquidity
and, to the extent IAI's view as to certain market  movements is incorrect,  the
risk that the use of such  techniques  and  instruments  could  result in losses
greater  than if they had not been used.  Use of put and call options may result
in losses to a Fund,  force the sale or  purchase  of  portfolio  securities  at
inopportune  times or for prices  higher  than (in the case of put  options)  or
lower  than (in the case of call  options),  current  market  values,  limit the
amount of  appreciation a Fund can realize on its investments or cause a Fund to
hold a security it might  otherwise sell. The use of currency  transactions  can
result in a Fund incurring  losses as a result of a number of factors  including
the imposition of exchange controls,  suspension of settlements or the inability
to deliver or  receive a  specified  currency.  The use of options  and  futures
transactions entails certain other risks. In particular,  the variable degree of
correlation  between price movements of futures contracts and price movements in
the related portfolio  position of a Fund creates the possibility that losses on
the  hedging  instrument  may be  greater  than  gains in the  value of a Fund's
position.  In  addition,  futures and  options  markets may not be liquid in all
circumstances and certain  over-the-counter  options may not have markets.  As a
result, in certain markets,  a Fund might not be able to close out a transaction
without  incurring  substantial  losses,  if at all. Although the use of futures
contracts and options  transactions for hedging should tend to minimize the risk
of loss due to a decline in the value of the hedged  position,  at the same time
they tend to limit any  potential  gain which  might  result from an increase in
value of such position.  Finally,  the daily variation  margin  requirements for
future  contracts would create a greater ongoing  potential  financial risk than
would  purchases  of options,  where the  exposure is limited to the cost of the
initial premium.  Losses resulting from the use of these techniques would reduce
net asset value, and possibly income, and such losses can be greater than if the
techniques and instruments had not been utilized.

RISKS OF LOWER-RATED DEBT 
SECURITIES

Developing Countries Fund may invest in debt securities commonly known as "junk"
bonds.   Such  securities  are  subject  to  higher  risks  and  greater  market
fluctuations than are lower-yielding, higher-rated securities. The price of junk
bonds has been found to be less  sensitive  to changes  in  prevailing  interest
rates  than  higher-rated  investments,  but is likely to be more  sensitive  to
adverse  economic  changes  or  individual  corporate  developments.  During  an
economic  downturn  or  substantial  period of  

- -18-
<PAGE>
                                IAI MUTUAL FUNDS
             IAI DEVELOPING COUNTRIES FUND, IAI INTERNATIONAL FUND


rising interest rates, highly leveraged issuers may experience  financial stress
which would  adversely  affect  their  ability to service  their  principal  and
interest  payment  obligations,  to meet their  projected  business  goals or to
obtain additional financing.  If the issuers of a fixed-income security owned by
Developing Countries Fund were to default, Developing Countries Fund might incur
additional expenses to seek recovery. The risk of loss due to default by issuers
of junk bonds is  significantly  greater than that associated with  higher-rated
securities  because such  securities  generally are unsecured and frequently are
subordinated to the prior payment of senior indebtedness.  In addition,  periods
of economic  uncertainty  and change can be  expected to result in an  increased
volatility of market  prices of junk bonds and a  concomitant  volatility in the
net asset value of a share of Developing Countries Fund.

The  secondary  market for junk bonds is less liquid than the markets for higher
quality securities and, as such, may have an adverse effect on the market prices
of certain  securities.  The limited  liquidity of the market may also adversely
affect the ability of  Developing  Countries  Fund to arrive at a fair value for
certain junk bonds at certain times and could make it difficult  for  Developing
Countries Fund to sell certain securities.  For a description of Moody's and S&P
ratings, see Appendix A to the Statement of Additional Information.

RISK FACTORS ASSOCIATED WITH 
INVESTING IN SMALL COMPANIES

Investing  in  small  companies   involves  greater  risk  than  is  customarily
associated with  investments in larger,  more  established  companies due to the
greater business risks of small size,  limited markets and financial  resources,
narrow  product  lines  and  the  frequent  lack of  depth  of  management.  The
securities of small companies are often traded  over-the-counter  and may not be
traded in volumes typical on a national securities exchange.  Consequently,  the
securities  of small  companies  may have limited  market  stability  and may be
subject to more abrupt or erratic market  movements  than  securities of larger,
more established companies or the market averages in general.  Therefore, to the
extent International Fund invests in small companies,  its shares may be subject
to greater  fluctuation in value than shares of a conservative equity fund or of
a growth fund which invests entirely in more established stocks.

INVESTMENT RESTRICTIONS

Each Fund is subject to  certain  other  investment  policies  and  restrictions
described  in the  Statement  of  Additional  Information,  some  of  which  are
fundamental and may not be changed  without the approval of the  shareholders of
the Fund. As a fundamental policy, with respect to 75% of its total assets, each
Fund may not invest  more than 5% of its total  assets in any one  issuer.  Each
Fund may not invest 25% or more of its assets in any 

                                                                            -19-

an amount not  exceeding  one-third  of its total  assets.  Please  refer to the
Statement of  Additional  Information  for a further  discussion  of each Fund's

MANAGEMENT

Developing  Countries Fund and  International  Fund were created on February 10,
1995 and April 23, 1987,  respectively,  as separate  portfolios  represented by
separate  classes of common stock of IAI Investment Funds III, Inc., a Minnesota
corporation  created on September  16, 1986.  Under  Minnesota  law, each Fund's
Board of  Directors  is  generally  responsible  for the overall  operation  and
management of each Fund. IAI serves as the investment  adviser to each Fund. IAI
has  delegated  to  IAI  International   certain  of  its  responsibilities  and
obligations as the Funds'  investment  adviser  pursuant to a written  agreement
(the  "Subadvisory  Agreement").  IAI  International  is  based  in  London  and
maintains a United  States  representative  office with the same address as IAI.
IAI  also  furnishes   investment  advice  to  other  concerns  including  other
investment   companies,   pension  and  profit  sharing  plans,   portfolios  of
foundations,   religious,  educational  and  charitable  institutions,   trusts,
municipalities and individuals,  and has total assets under management in excess
of $16 billion.  The ultimate  corporate parent of IAI and IAI  International is
Lloyds  TSB  Group  plc,  a  publicly  held  financial   services   organization
headquartered  in London,  England.  Lloyds TSB Group plc is one of the  largest
personal and corporate  financial  services  groups in the United Kingdom and is
engaged in a wide range of activities  including  commercial and retail banking.
The address of IAI is that of the Funds.

Pursuant to a written agreement with each Fund (the "Management Agreement"), IAI
provides each Fund with investment  advisory services and is responsible for the
overall  management of each Fund's business  affairs subject to the authority of
the Board of Directors.  The Management Agreement also provides that, except for
brokerage commissions and other expenditures in connection with the purchase and
sale of portfolio securities, interest and, in certain circumstances,  taxes and
extraordinary  expenses,  IAI shall pay all of a Fund's operating  expenses.  As
compensation  under the  Management  Agreement,  Developing  Countries  Fund has
agreed to pay IAI a monthly  advisory fee at the initial annual rate of 2.00% of
the Fund's  average daily net assets,  which fee declines to 1.65% of the Fund's
average  daily net assets as the amount of assets in Developing  Countries  Fund
grows. With respect to International  Fund, the Fund has agreed to pay a monthly
advisory fee at the initial annual rate of 1.70% of the Fund's average daily net
assets,  which fee declines to 1.30% of the Fund's  average  daily net assets as

 .50% of  average  daily  net  assets  which  declines  to .35% as the  assets in
International Fund grows.  Because IAI is paying Fund operating expenses,  these
fees  represent  each  Fund's  total  expenses.  With  respect to certain of the
services for which it is  responsible  under the Management  Agreement,  IAI may
also pay qualifying  broker-dealers,  financial  institutions and other entities
for providing  such services to Fund  shareholders.  IAI shall not be liable for
any loss suffered by a Fund in the absence of willful misfeasance,  bad faith or
negligence in the performance of its duties and obligations.

Roy  Gillson  and  Sookyong  Kwak  have  responsibility  for the  management  of
Developing  Countries Fund. Mr. Gillson is IAI International's  Chief Investment
Officer  and a  member  of its  Board  of  Directors.  Mr.  Gillson  joined  IAI
International  in 1983 and has  managed  Developing  Countries  Fund  since  its
inception in February  1995.  Ms. Kwak is an Associate  Director and has managed
the Fund since June 1996. Ms. Kwak joined IAI  International  in 1995. From 1989
to 1990, she served as a research analyst with Neuberger & Berman, and from 1990
to 1992 she was employed by Brown Brothers  Harriman in a similar  capacity.  In
1992, Ms. Kwak joined the International Finance Corporation, a private sector of
the World Bank, where she served as a research analyst until 1995.

Mr. Gillson has  responsibility for the management of the International Fund and
has managed the Fund since 1990.

Consistent  with the  Rules of Fair  Practice  of the  National  Association  of
Securities Dealers, Inc., IAI may consider sales of shares of a Fund as a factor
in the selection of broker-dealers to execute a Fund's securities transactions.

INVESTMENT 
PERFORMANCE

From time to time the Funds may advertise  performance  data including  monthly,
quarterly,  yearly or  cumulative  total return and average  annual total return
figures.  All such figures are based on historical  earnings and performance and
are not intended to be indicative of future  performance.  The investment return
on and principal value of an investment in the Funds will fluctuate,  so that an
investor's shares, when redeemed,  may be worth more or less than their original
cost.

Total  return  is the  change in value of an  investment  in a Fund over a given
period,  assuming  reinvestment of any dividends and capital gains. A cumulative
total  return  reflects  actual  performance  over a stated  period of time.  An
average annual total return is a  hypothetical  rate of return that, if achieved
annually,  would have produced the same  cumulative  total return if performance
had been constant over the entire period.

For  additional  information  regarding  the  calculation  of such total  return
figures,   see   "Investment   Performance"   in  the  

                                                                            -21-

Statement of Additional  Information.  Further information about the performance
of  the  International  Fund  is  contained  in  the  Fund's  Annual  Report  to
shareholders which may be obtained without charge from the Fund.

Comparative performance information may be used from time to time in advertising
or marketing a Fund's shares,  including data on the performance of other mutual
funds,  indexes or averages of other mutual funds,  indexes of related financial
assets or data, and other competing  investment and deposit  products  available
from or through other financial institutions.  The composition of these indexes,
averages or products differs from that of the Funds. The comparison of a Fund to
an alternative  investment  should be made with  consideration of differences in
features  and  expected  performance.  A Fund  may  also  note  its  mention  in
newspapers,  magazines,  or other media from time to time.  The Funds  assume no
responsibility for the accuracy of such data. For additional  information on the
types of indexes,  averages and periodicals  that might be utilized by the Funds
in advertising and sales literature, see the section "Investment Performance" in
the Statement of Additional Information.

COMPUTATION OF NET 
ASSET VALUE AND PRICING

Each Fund is open for business each day the New York Stock Exchange  ("NYSE") is
open.  IAI normally  calculates a Fund's net asset value ("NAV") as of the close
of business of the NYSE, normally 3 p.m. Central time.

A Fund's NAV is the value of a single  share.  The NAV is  computed by adding up
the value of a Fund's  investments,  cash,  and other  assets,  subtracting  its
liabilities, and then dividing the result by the number of shares outstanding.

A Fund's investments with remaining  maturities of 60 days or less may be valued
on the basis of amortized cost. This method minimizes the effect of changes in a
security's  market  value.  Other  portfolio  securities  and  assets are valued
primarily on the basis of market  quotations  or, if quotations  are not readily
available,  by a method that the Board of Directors believes accurately reflects
fair value.  Foreign  securities are valued on the basis of quotations  from the
primary market in which they are traded.

Because  of the  Funds'  need to obtain  prices as of the  close of  trading  on
various exchanges  throughout the world, the calculation of net asset value does
not take  place  contemporaneously  with the  determination  of the  prices of a
Fund's  portfolio  securities.  For purposes of  determining  a Fund's net asset
value, all assets and liabilities initially expressed in foreign currency values
will be converted into U.S.  dollar values using current  exchange  rates. If an
event were to occur after the value of a Fund  instrument was so established but
before  the net  asset  value  per  share is  determined  which  was  likely  to
materially  change the net asset value,  such  instrument  shall be valued using
fair value considerations by the Board of Directors or its delegates.

The offering price (price to buy one share) and redemption  price (price to sell
one share) are referred to as a Fund's NAV.

PURCHASE OF SHARES

Each Fund offers its shares  continually to the public at the net asset value of
such shares.  Shares may be purchased  directly  from a Fund or through  certain
security  dealers who have  responsibility  to promptly  transmit orders and may
charge a processing fee, provided that the Fund whose shares are being purchased
is duly registered in the state of the purchaser's  residence,  if required, and
the purchaser  otherwise  satisfies the Fund's purchase  requirements.  No sales
load or commission is charged in connection with the purchase of Fund shares.

The minimum initial investment to establish a retail account with the IAI Family
of Funds is $5,000.  Such initial  investment may be allocated  among a Fund and
other  funds in the IAI Family of Funds as desired,  provided  that no less than
$1,000 is  allocated to any one fund.  The minimum  initial  investment  for IRA
accounts is $2,000,  provided  that the minimum  amount that may be allocated to
any one fund is  $1,000.  Once the  account  minimum  has been  met,  subsequent
purchases  can be made in a Fund for $100 or more.  Such  minimums may be waived
for participants in the IAI Investment Club.

Investors may satisfy the minimum investment requirement by participating in the
STAR Program.  Participation in the STAR Program requires an initial  investment
of $1,000 per Fund and a commitment  to invest an aggregate of $5,000  within 24
months. If a STAR Program  participant does not invest an aggregate of $5,000 in
the IAI Family of Funds  within 24 months,  IAI may, at its option,  redeem such
shareholder's  interest.  Investors  wishing to  participate in the STAR Program
should contact a Fund to obtain a STAR Program application.

To purchase  shares,  forward the completed  application  and a check payable to
"IAI  Funds" to a Fund.  Third party  checks  will not be  accepted  for initial
account investments. Upon receipt, your account will be credited with the number
of full and fractional shares which can be purchased at the net asset value next
determined after receipt of the purchase order by a Fund.

Purchases of shares are subject to acceptance or rejection by a Fund on the same
day the purchase order is received and are not binding until so accepted.  It is
the policy of the Funds and the  Underwriter  to keep  confidential  information
contained  in the  application  and  regarding  the  account of an  investor  or
potential investor in the Funds.

All correspondence  relating to the purchase of shares should be directed to the
office of the Fund,  P.O.  Box 357,  Minneapolis,  Minnesota  55440 or, if using
overnight delivery, to 3700 First Bank Place, 601 2nd Avenue South, Minneapolis,
Minnesota 55402. For assistance in completing the application please contact IAI
Mutual Fund Shareholder Services at 1-800-945-3863.

BANK WIRE PURCHASES

Shares may be  purchased  by having your bank wire  federal  funds (funds of the
Federal Reserve System) to Norwest Bank Minnesota.

Wire orders will be accepted only on days your bank, the transfer  agent, a Fund
and Norwest Bank  Minnesota are open for business.  The payment must be received
by a Fund before the close of business to be credited to your  account that day.
Otherwise,  it will be processed  the next  business day. The wire purchase will
not be  considered  made until the wired  amount is received and the purchase is
accepted by such Fund. If the wire order does not contain the information stated
below,  such Fund may reject it.  Any  delays  that may occur in wiring  federal
funds,  including delays in processing by the banks, are not the  responsibility
of such Fund or the transfer agent.

You must pay any charges  assessed by your bank for the wire service.  If a wire
order is rejected,  all money  received by the Fund,  less any costs incurred by
the Fund or the transfer agent in rejecting it, will be returned promptly.

If the wire order is for a new account, you should call IAI Shareholder Services
at  1-800-945-3863  to advise  them of the  investment  and to obtain an account
number and  instructions.  The wire should be sent to:  Norwest Bank  Minnesota,
Routing Number 091000019,  Minneapolis,  Minnesota,  Credit to: IAI Mutual Funds
Account Number 6355002264. It should state the following:

"For further credit to personal account #  ______________  (your account number)
for ______________________ (your name) and __________________ (Fund name)."

A completed application must be sent to and received by the Fund before the wire
is sent.

If the wire order is an addition to an existing  account,  the wire must include
the  information  required  above for the new  accounts.  As soon as the wire is
sent, you should call IAI Shareholder  Services,  as described above, and advise
them of your name, your account number and the name of the bank transmitting the
federal funds.

RETIREMENT PLANS

Shares of Developing Countries Fund and International Fund may be an appropriate
investment  medium for various  retirement plans.  Persons desiring  information
about establishing an Individual  Retirement Account (IRA) (for employed persons
and  their  spouses)  or  other  retirement  plans  should  contact  a  Fund  at
1-800-945-3863.  All retirement  plans involve a long-term  commitment of assets
and are subject to various legal  requirements and  restrictions.  The legal and
tax  implications  may vary  according to the  circumstances  of the  individual
investor.  Therefore,  you are urged to consult  with an attorney or tax adviser
prior to the establishment of such a plan.

AUTOMATIC INVESTMENT PLAN

Investors may arrange to make regular  investments of $100 or more per fund on a
monthly  basis,  effective  as of the 4th or 18th day of each month (or the next
business  day),  through  automatic  deductions  from their  checking or savings
account.  Such investors may, of course,  terminate their  participation  in the
Automatic  Investment Plan at anytime upon written notice to a Fund. Any changes
or  instructions  to  terminate  existing  Automatic  Investment  Plans  must be
received 30 days preceding the day on which the change or termination is to take
place.  Investors  interested in participating in the Automatic  Investment Plan
should  complete the Automatic  Investment  Plan  application and return it to a
Fund.

REDEMPTION OF SHARES

Registered holders of Fund shares may at any time require a Fund to redeem their
shares upon their written request. All correspondence relating to the redemption
of shares  should be directed to the office of IAI Mutual  Funds,  P.O. Box 357,
Minneapolis,  Minnesota 55440.  Shareholders may redeem shares by phone, subject
to a limit of $50,000,  provided such  shareholders have authorized such Fund to
accept  telephone  instructions.  For  assistance in redeeming  shares by phone,
please contact the IAI Mutual Funds Shareholder Services at 1-800-945-3863.

Certificates  presented  for  redemption  must be  endorsed on the back with the
signature  of the person  whose  name  appears  on the  certificate  and must be
signature guaranteed. If no certificate has been issued, redemption instructions
must be signed by the person(s) in whose name the shares are registered.  If the
redemption  proceeds  are to be paid or  mailed  to any  person  other  than the
shareholder of record or if redemption proceeds are in excess of $50,000, a Fund
will require that the signature on the written  instructions  be guaranteed by a
participant in a signature guarantee program, which may include certain national
banks or  trust  companies  or  certain  member  firms  of  national  securities
exchanges.  (Notarization by a Notary Public is NOT ACCEPTED.) If the shares are
held of record in the name of a corporation,  partnership, trust or fiduciary, a
Fund may require  additional  evidence of authority prior to accepting a request
for redemption.

For shareholders who established receiving proceeds by Federal Funds Wire at the
time they opened  their  account,  telephone  instructions  will be accepted for
redemption of amounts up to $50,000 ($1,000  Minimum) and proceeds will be wired
on the next  business  day to a  predesignated  bank  account.  Wire  redemption
requests will only be processed on days your bank, the transfer agent, the Funds
and Norwest Bank Minnesota are open for business.

In order to add this feature to an existing  account or to change  existing bank
account information,  please submit a letter of instructions including your bank
information  to IAI  Shareholder  Services at the address  listed in the section
"Additional  Information."  The letter must be signed by all registered  owners,
and their signatures must be guaranteed.

Your  account  will be charged a fee of $10 each time  redemption  proceeds  are
wired to 

                                                                            -25-

your bank.  Your bank may also charge you a fee for  receiving  a Federal  Funds
Wire.

Neither  the  transfer  agent nor any of the Funds  can be  responsible  for the
efficiency of the Federal Funds wire system or the shareholder's bank.

The  redemption  proceeds  received by the  investor  are based on the net asset
value next determined after  redemption  instructions in good order are received
by a Fund.  Since the value of shares redeemed is based upon the value of a Fund
investment  at the time of  redemption,  it may be more or less  than the  price
originally paid for the shares.

Payment for shares  redeemed  will  ordinarily be made within seven days after a
request  for  redemption  has been made.  Normally a Fund will mail  payment for
shares redeemed on the business day following receipt of the redemption request.
A Fund will not send  redemption  proceeds  until  checks  (including  certified
checks or cashiers  checks)  received in payment for shares have cleared,  which
may take up to ten days or more.
                                      
Following a  redemption  or transfer  request,  if the value of a  shareholder's
interest in a Fund falls below $500, such Fund reserves the right to redeem such
shareholder's entire interest and remit such amount. Such a redemption will only
be effected  following:  (a) a  redemption  or transfer by a  shareholder  which
causes the value of such shareholder's interest in such Fund to fall below $500;
(b) the mailing by such Fund to such  shareholder  of a notice of  intention  to
redeem;  and (c) the  passage  of at  least  six  months  from  the date of such
mailing,  during which time the investor  will have the  opportunity  to make an
additional  investment  in such Fund to  increase  the value of such  investor's
account to at least $500.

EXCHANGE PRIVILEGE

The Exchange Privilege enables shareholders to purchase,  in exchange for shares
of a Fund,  shares of  certain  other  funds  managed by IAI.  These  funds have
different investment objectives from the Funds. Shareholders may exchange shares
of a Fund for shares of another  fund  managed  by IAI,  provided  that the fund
whose  shares  will  be  acquired  is  duly  registered  in  the  state  of  the
shareholder's  residence  and the  shareholder  otherwise  satisfies  the fund's
purchase requirements.  Although the Funds do not currently charge a fee for use
of the Exchange Privilege, they reserve the right to do so in the future.

Because excessive trading can hurt Fund performance and shareholders, there is a
limit of four exchanges out of each Fund per calendar year per account. Accounts
under common  ownership or control,  including  accounts  with the same taxpayer
identification  number,  will be  counted  together  for  purposes  of the  four
exchange  limit.  Each Fund  reserves the right to  temporarily  or  permanently
terminate  the Exchange  Privilege  of any investor who exceeds this limit.  The
limit may be modified for certain  retirement plan accounts,  as required by the
applicable plan document and/or relevant  Department of Labor  regulations,  and
for Automatic Exchange Plan  participants.  Each Fund also reserves the right to
refuse or limit exchange  purchases by any investor if, in IAI's judgment,  such
Fund  would be unable to invest the money  effectively  in  accordance  with its
investment

objectives and policies, or would otherwise potentially be adversely affected.

Fund  shareholders  wishing to exercise the Exchange  Privilege  should notify a
Fund in writing or, provided such  shareholders have authorized a Fund to accept
telephone  instructions,  by telephone.  At the time of the exchange, if the net
asset value of the shares  redeemed in  connection  with the exchange is greater
than the  investor's  cost, a taxable  capital gain will be realized.  A capital
loss will be realized if at the time of the  exchange the net asset value of the
shares  redeemed in the  exchange is less than the  investor's  cost.  Each Fund
reserves the right to terminate or modify the Exchange Privilege in the future.

AUTOMATIC EXCHANGE
PLAN

Investors  may arrange to make regular  exchanges of $100 or more between any of
the funds in the IAI Mutual Fund Family on a monthly basis.  Exchanges will take
place at the closing  price of the fifth day of each month (or the next business
day).  Shareholders  are responsible for making sure sufficient  shares exist in
the Fund  account  from  which  the  exchange  takes  place.  If  there  are not
sufficient funds in a Fund account to meet the requested  exchange  amount,  the
Automatic  Exchange  Plan will be  suspended.  Shareholders  may not close  Fund
accounts  through  the  Automatic   Exchange  Plan.   Investors   interested  in
participating  in the  Automatic  Exchange  Plan should  complete the  Automatic
Exchange Plan portion of their  application.  For  assistance in completing  the
application contact IAI Mutual Fund Shareholder Services at 1-800-945-3863.

AUTHORIZED 
TELEPHONE TRADING

Investors can transact  account  exchanges and  redemptions via the telephone by
completing  the  Authorized  Telephone  Trading  section of the IAI Mutual  Fund
application and returning it to a Fund.  Investors  requesting telephone trading
privileges will be provided with a personal  identification  number ("PIN") that
must accompany any  instructions by phone.  Shares will be redeemed or exchanged
at the next  determined  net asset  value.  Telephone  redemption  proceeds  are
subject to a $50,000  limit and must be made  payable to the  owner(s) of record
and delivered to the address of record.

In order to confirm that telephone  instructions  for  redemptions and exchanges
are genuine,  the Fund has  established  reasonable  procedures,  including  the
requirement  that  a  personal   identification   number   accompany   telephone
instructions. If a Fund or transfer agent fails to follow these procedures, such
Fund may be liable for losses due to unauthorized or fraudulent instructions. To
the extent these reasonable  procedures are followed,  none of the Funds,  their
transfer  agent,  IAI, or any  affiliated  broker-dealer  will be liable for any
loss, injury, damage, or expense for acting upon telephone instructions believed
to be genuine, and will otherwise not be responsible for the authenticity of any
telephone  instructions,  and, accordingly,  the investor bears the risk of loss
resulting from telephone  instructions.  All telephone  redemptions and exchange
requests will be tape recorded.  Telephone  redemptions are not permitted on IRA
or  Simplified  Employee  

                                                                            -27-

Pension ("SEP") accounts. Please call a Fund for a distribution form.

SYSTEMATIC CASH 
WITHDRAWAL PLAN

Each Fund has  available a  Systematic  Cash  Withdrawal  Plan for any  investor
desiring to follow a program of  systematically  withdrawing  a fixed  amount of
money from an  investment in shares of a Fund.  Payments  under the plan will be
made monthly or  quarterly in amounts of $100 or more.  Shares will be sold with
the  closing  price of the 15th of the  applicable  month (or the next  business
day).  To  provide  funds  for  payment,  a Fund  will  redeem  as many full and
fractional  shares as  necessary  at the  redemption  price,  which is net asset
value.  The  holder of a  Systematic  Cash  Withdrawal  Plan  must  have  income
dividends and any capital gains distributions  reinvested in full and fractional
shares at net asset value.

Payments under this plan,  unless pursuant to a retirement  plan,  should not be
considered  income.  Withdrawal  payments may exceed dividends and distributions
and, to this extent,  there will be a reduction  in the  investor's  equity.  An
investor should also understand that this plan cannot insure profit, nor does it
protect against any loss in a declining market.  Careful consideration should be
given to the amount withdrawn each month.  Excessive withdrawals could lead to a
serious  depletion of equity,  especially  during  periods of  declining  market
values. Fund management will be available for consultation in this matter.

Plan  application  forms are  available  through  the  Funds.  If you would like
assistance in completing  the  application  contact IAI Mutual Fund  Shareholder
Services at 1-800-945-3863.

DIVIDENDS, 
DISTRIBUTIONS AND 
TAX STATUS

The policy of Developing  Countries Fund is to pay dividends from net investment
income and to make  distributions of realized  capital gains, if any,  annually.
The policy of International  Fund is to pay dividends from net investment income
semiannually  and to make  distributions  of  realized  capital  gains,  if any,
annually.  However,  provisions in the Internal Revenue Code of 1986, as amended
(the "Code"),  may result in additional net investment  income and capital gains
distributions  by a Fund.  When you open an account,  you should specify on your
application how you want to receive your  distributions.  Each Fund offers three
options: Full Reinvestment--your dividend and capital gain distributions will be
automatically  reinvested  in  additional  shares  of the  Fund;  Capital  Gains
Reinvestment--your  capital gain distributions will be automatically reinvested,
but your  income  dividend  distribution  will be paid in cash;  and  Cash--your
income  dividends  and  capital  gain   distributions  will  be  paid  in  cash.
Distributions  taken in cash can be sent via check or  transferred  directly  to
your  account at any bank,  savings and loan or credit union that is a member of
the Automated Clearing House (ACH) network. Unless indicated

otherwise by the  shareholder,  each Fund will  automatically  reinvest all such
distributions into full and fractional shraes at net asset value.

The Funds' Directed  Dividend service allows you to invest your dividends and/or
capital gain  distributions  directly into another IAI Mutual Fund.  Contact IAI
Mutual Fund Shareholder Services at 1-800-945-3863 for details.

Each Fund intends to qualify as a regulated  investment company under Subchapter
M of the Code during its current  taxable year. If so qualified,  such Fund will
not be subject  to  federal  income  tax on income  that it  distributes  to its
shareholders.
                                     
Distributions by the Funds to shareholders, except distributions to shareholders
not  subject  to  federal  income  taxation,   are  generally   taxable  to  the
shareholders,  whether received in cash or additional Fund shares. Distributions
paid out of the Funds' net investment  income and net  short-term  capital gains
are taxable to shareholders as ordinary  income.  Distributions  paid out of the
Funds'  net  long-term  capital  gains and  designated  as such are  taxable  to
shareholders as long-term  capital gains,  regardless of the length of time that
they have held their shares in a Fund.

A Fund may be required  to pay  withholding  and other taxes  imposed by foreign
countries,  generally  at rates from 10% to 40%,  which would reduce such Fund's
investment  income.  Tax conventions  between  certain  countries and the United
States may reduce or  eliminate  such taxes.  If a Fund has more than 50% of its
assets invested in the stock or securities of foreign corporations at the end of
such Fund's  taxable year,  the Fund may make an election to allow  shareholders
either to claim U.S.  foreign tax credits with respect to foreign  taxes paid by
the Fund or to deduct such amounts as an itemized deduction on their tax return.
In the event such an election is made, shareholders would have to increase their
taxable  income by the  amount of such  taxes and the Fund  would not be able to
deduct such taxes in computing its taxable income.

Alternatively, if the amount of foreign taxes paid by a Fund is not large enough
to warrant  its making the  election  described  above,  such Fund may claim the
amount of foreign  taxes paid as a deduction  against its own gross  income.  In
that case,  shareholders  would not be required to include any amount of foreign
taxes  paid by the Fund in their  income  and would not be  permitted  either to
deduct any portion of foreign taxes from their own income or to claim any amount
of foreign tax credit for taxes paid by the Fund.

Information about the tax status of dividends and distributions from a Fund will
be mailed to such Fund's shareholders annually.

In general,  upon redemption of shares of a Fund, the shareholder will recognize
taxable gain or loss equal to the difference  between the amount realized on the
redemption and the  shareholder's  adjusted  basis in such shares.  Such gain or
loss will be  capital  gain or loss for any  shareholder  who is not a dealer in

The foregoing  relates to federal income taxation as in effect as of the date of
the Prospectus.  Distributions  from net investment income and from net realized
capital gains may also be subject to state and local taxes.  For a more detailed

DESCRIPTION OF 
COMMON STOCK

All  shares of each Fund have  equal  rights  as to  redemption,  dividends  and
liquidation,  and will be fully paid and nonassessable when issued and will have
no preemptive or conversion rights.

The shares of each Fund have noncumulative  voting rights,  which means that the
holders of more than 50% of the shares  voting for the election of directors can
elect 100% of the directors if they choose to do so. On some issues, such as the
election  of  directors,  all  shares of IAI  Investment  Funds III,  Inc.  vote
together as one series. On an issue affecting only a particular series,  such as
voting on the Management Agreement,  only the approval of a particular series is
required to make the agreement effective with respect to such series.

Annual or periodically  scheduled  regular meetings of shareholders  will not be
held except as required by law.  Minnesota  corporation  law does not require an
annual  meeting;  instead,  it provides  for the Board of  Directors  to convene
shareholder  meetings  when it deems  appropriate.  In  addition,  if a  regular
meeting  of  shareholders  has not been held  during the  immediately  preceding
fifteen months,  shareholders holding three percent or more of the voting shares
of each  Fund may  demand a  regular  meeting  of  shareholders  of such Fund by
written  notice of  demand  given to the chief  executive  officer  or the chief
financial  officer of such Fund.  Within thirty days after receipt of the demand
by one of those  officers,  the Board of Directors shall cause a regular meeting
of shareholders to be called and held no later than ninety days after receipt of
the demand,  all at the expense of such Fund. An annual  meeting will be held on
the  removal of a director or  directors  of a Fund if  requested  in writing by
holders of not less than 10% of the outstanding shares of a Fund.

The shares of each Fund are  transferable  by  delivery  to the Fund of transfer
instructions.  Transfer  instructions  should be  delivered to the office of the
Fund.  The Fund is not bound to recognize  any transfer  until it is recorded on
the stock transfer books maintained by the Fund. Certificates  representing Fund
shares will not be issued.

COUNSEL AND 
AUDITORS

The firm of Dorsey & Whitney LLP, 220 South Sixth Street, Minneapolis, Minnesota
55402,  provides legal counsel to the Funds. KPMG Peat Marwick LLP, 4200 Norwest
Center,  Minneapolis,  Minnesota 55402,  serves as independent  auditors for the
Funds.

In the opinion of the staff of the Securities and Exchange  Commission,  the use
of this combined  prospectus may possibly  subject all Funds to a certain amount
of  liability  for any losses  arising out of any  statement or omission in this
Prospectus regarding a particular Fund. In the opinion of the Funds' management,
however,  the risk of such  liability  is not  materially  increased by use of a
combined prospectus.

Shareholder inquiries should be directed to the Funds at the telephone number or
mailing address listed on the inside back cover page of this Prospectus. -24-

                        INVESTMENT OBJECTIVE AND POLICIES

     The  investment  objective and policies of IAI  Developing  Countries  Fund
("Developing  Countries Fund") and IAI International Fund ("International Fund")
are  summarized  on the  front  page of the  Prospectus  and in the  text of the
Prospectus  under   "Investment   Objective  and  Policies."   Investors  should
understand that all  investments  are subject to various risks.  There can be no
guarantee  against loss resulting from an investment in the Funds, and there can
be no assurance that a Fund's  investment  policies will be successful,  or that
its investment  objective will be attained.  Certain of the investment practices
of the Funds are further explained below.

REPURCHASE AGREEMENTS

     Each Fund may invest in repurchase agreements relating to the securities in
which it may invest. A repurchase  agreement involves the purchase of securities
with the condition that, after a stated period of time, the original seller will
buy back the securities at a  predetermined  price or yield. A Fund's  custodian
will have custody of, and will hold in a segregated account, securities acquired
by such Fund under a repurchase agreement or other securities as collateral.  In
the case of a security registered on a book entry system, the book entry will be
maintained  in a Fund's  name or that of its  custodian.  Repurchase  agreements
involve certain risks not associated with direct investments in securities.  For
example, if the seller of the agreement defaults on its obligation to repurchase
the  underlying  securities  at a time  when  the  value of the  securities  has
declined,  a Fund may incur a loss upon disposition of such  securities.  In the
event that  bankruptcy  proceedings  are commenced with respect to the seller of
the  agreement,  a Fund's  ability to dispose of the  collateral  to recover its
investment may be restricted or delayed.  While  collateral will at all times be
maintained  in an amount  equal to the  repurchase  price  under  the  agreement
(including  accrued  interest due  thereunder),  to the extent proceeds from the
sale of collateral  were less than the  repurchase  price, a Fund could suffer a
loss.

REVERSE REPURCHASE AGREEMENTS

     Each  Fund  may  invest  in  reverse  repurchase  agreements  as a form  of
borrowing.  In  a  reverse  repurchase  agreement,  a  Fund  sells  a  portfolio
instrument to another party, such as a bank or broker-dealer, in return for cash
and agrees to repurchase the instrument at a particular  price and time. While a
reverse repurchase  agreement is outstanding,  a Fund will maintain  appropriate
liquid assets in a segregated  custodial  account to cover its obligation  under
the agreement. The Funds will enter into reverse repurchase agreements only with
parties  whose  creditworthiness  has  been  found  satisfactory  by  Investment
Advisers,  Inc.  ("IAI"),  the  Funds'  investment  adviser  and  manager or IAI
International   Limited  (hereinafter   references  to  IAI  shall  include  IAI
International  Limited where  appropriate),  the  subadviser to the Funds.  Such
transactions  may increase  fluctuations  in the market value of a Fund's assets
and may be viewed as a form of leverage.  Each Fund does not currently intend to
invest more than 5% of its net assets in reverse repurchase agreements.

SECURITIES OF FOREIGN ISSUERS

     Investing  in  foreign  securities  may  result in  greater  risk than that
incurred by investing in domestic  securities.  There is generally less publicly
available  information  about foreign issuers  comparable to reports and ratings
that are published about companies in the United States.  Also,  foreign issuers
are  not  subject  to  uniform  accounting,  auditing  and  financial  reporting
standards,  practices and requirements  comparable to those applicable to United
States companies.

                                      -2-
<PAGE>


     It is  contemplated  that most  foreign  securities  will be  purchased  in
over-the-counter markets or on stock exchanges located in the countries in which
the respective  principal  offices of the issuers of the various  securities are
located,  if that is the  best  available  market.  Foreign  stock  markets  are
generally  not as developed or  efficient as those in the United  States.  While
growing in volume, they usually have substantially less volume than the New York
Stock  Exchange,  and  securities of some foreign  companies are less liquid and
more volatile than securities of comparable United States companies.  Similarly,
volume and  liquidity  in most  foreign bond markets are less than in the United
States  and at times  volatility  of price  can be  greater  than in the  United
States.  Commissions  on foreign  stock  exchanges  are  generally  higher  than
commissions  on United  States  exchanges,  although the Funds will  endeavor to
achieve the most favorable net results on its portfolio  transactions.  There is
generally less government supervision and regulation of foreign stock exchanges,
brokers and listed companies than in the United States.

     With respect to certain  foreign  countries,  there is the  possibility  of
adverse changes in investment or exchange control regulations,  expropriation or
confiscatory  taxation,  limitations  on the removal of funds or other assets of
the Funds,  political or social  instability,  or diplomatic  developments which
could affect United States investments in those countries.  Moreover, individual
foreign  economies may differ  favorably or unfavorably  from the United States'
economy in such respects as growth of gross national product, rate of inflation,
capital  reinvestment,   resource   self-sufficiency  and  balance  of  payments
position.

     The dividends and interest payable on certain of a Fund's foreign portfolio
securities may be subject to foreign  withholding  taxes,  thus reducing the net
amount of income available for distribution to such Fund's shareholders.

ILLIQUID SECURITIES

     Developing  Countries  Fund  may  invest  up to 10% of its  net  assets  in
illiquid securities,  and the International Fund may invest up to 15% of its net
assets in illiquid securities.  However,  certain restricted securities that are
not   registered  for  sale  to  the  general  public  that  can  be  resold  to
institutional  investors may be considered liquid pursuant to guidelines adopted
by the Board of Directors. In the case of a Rule 144A Security, such security is
deemed to be liquid if:

     (1) IAI reasonably expects to be able to resell the security to a qualified
institutional  buyer, as defined in paragraph  (a)(1) of Rule 144A, who is aware
of  the  Fund's  reliance  upon  Rule  144A  in  selling  the  security  without
registration, as required by paragraph (d)(2) of Rule 144A;

     (2) the  Rule  144A  Security  is not (a) of the same  class as  securities
listed on any  national  securities  exchange or quoted in NASDAQ as  determined
under  paragraph  (d)(3)(i)  of Rule  144A,  or (b) a security  of a  registered
investment company (other than a closed-end investment company); and

     (3) the issuer (a) is a foreign government  eligible to register securities
under  Schedule B of the  Securities  Act of 1933,  (b) is a company  that files
periodic  reports under the Securities  Act of 1934 on Forms 8-K, 10-Q,  10-K or
20-F or provides information under Rule 12g3-2(b) thereunder,  or (c) has agreed
in writing to provide the holder and any prospective  purchaser of the Rule 144A
Security  with  reasonably  current  financial  information  as  required  under
paragraph (d)(4)(i) of Rule 144A.

     Other  securities  are  deemed  to be  liquid  if IAI  determines  that the
security can be disposed of within seven days in the ordinary course of business
at  approximately  the amount at which the Funds have valued the  instrument for
purposes of calculating a Fund's net asset value. In making this  determination,
IAI will consider such factors as may be relevant to a Fund's ability to dispose
of the security,  including  but not limited to, the following  factors (none of
which, standing alone, would necessarily be determinative):

     1. the frequency of trades and quotes for the security;

     2. the number of dealers  willing to purchase or sell the  security and the
number of potential purchasers;

                                      -3-
<PAGE>
                                      
     3. dealer undertakings to make a market in the security; and

     4. the  nature of the  security  and the nature of the  marketplace  trades
(e.g.,  the time  needed to dispose of the  security,  the method of  soliciting
offers and the mechanics of transfer).

     It is  not  possible  to  predict  with  assurance  the  maintenance  of an
institutional  trading market for such  securities and the liquidity of a Fund's
investments could be impaired if trading declines.

LENDING PORTFOLIO SECURITIES

     In order to  generate  additional  income,  the  Funds  may lend  portfolio
securities to broker-dealers,  banks or other financial borrowers of securities.
As with other extensions of credit, there are risks of delay in recovery or even
loss of rights in the  collateral  should the  borrower of the  securities  fail
financially.  However,  a Fund  will only  enter  into  loan  arrangements  with
broker-dealers,  banks or other  institutions which IAI or IAI International has
determined are creditworthy under guidelines  established by the Funds' Board of
Directors.  The Funds  may also  experience  a loss if,  upon the  failure  of a
borrower to return loaned securities,  the collateral is not sufficient in value
or liquidity  to cover the value of such loaned  securities  (including  accrued
interest thereon).  However, a Fund will receive collateral in the form of cash,
United  States   Government   securities,   certificates  of  deposit  or  other
high-grade, short-term obligations or interest-bearing cash equivalents equal to
at least 102% of the value of the securities loaned. The value of the collateral
and of the securities  loaned will be marked to market on a daily basis.  During
the time  portfolio  securities  are on loan, the borrower pays a Fund an amount
equivalent to any dividends or interest  paid on the  securities  and a Fund may
invest the cash collateral and earn  additional  income or may receive an agreed
upon amount of interest income from the borrower.  However, the amounts received
by a Fund may be reduced by  finders'  fees paid to  broker-dealers  and related
expenses.  Presently,  each Fund does not intend to lend more than 5% of its net
assets to broker-dealers, banks, or other financial borrowers of securities.

SWAP AGREEMENTS

     Each  Fund  may  enter  into  swap  agreements.   Swap  agreements  can  be
individually  negotiated  and  structured  to include  exposure  to a variety of
different types of investments or market factors.  Depending on their structure,
swap  agreements  may  increase  or  decrease  a  Fund's  exposure  to  long- or
short-term  interest  rates (in the U.S. or abroad),  foreign  currency  values,
mortgage  securities,  corporate  borrowing  rates,  or  other  factors  such as
security  prices or inflation  rates.  Swap  agreements  can take many different
forms  and are  known  by a  variety  of  names.  A Fund is not  limited  to any
particular  form of swap agreement if IAI determines it is consistent  with such
Fund's investment objectives and policies.

     Swap  agreements will tend to shift a Fund's  investment  exposure from one
type of  investment  to  another.  For  example,  if a Fund  agrees to  exchange
payments in dollars for payments in foreign  currency,  the swap agreement would
tend to  decrease a Fund's  exposure to U.S.  interest  rates and  increase  its
exposure to foreign currency and interest rates. Depending on how they are used,
swap  agreements  may  increase or decrease the overall  volatility  of a Fund's
investments and its share price.

     The most  significant  factor in the  performance of swap agreements is the
change in the specific interest rate, currency,  or other factors that determine
the amounts of payments due to and from a Fund.  If a swap  agreement  calls for
payments by a Fund,  such Fund must be prepared to make such  payments when due.
In addition,  if the counterparty's  creditworthiness  declined,  the value of a
swap agreement would be likely to decline, potentially resulting in losses. Each
Fund expects to be able to eliminate its exposure under swap  agreements  either
by assignment  or other  disposition,  or by entering  into an  offsetting  swap
agreement with the same party or a similarly creditworthy party.

                                      -4-
<PAGE>


     Each Fund will maintain appropriate liquid assets in a segregated custodial
account to cover its current obligations under swap agreements. If a Fund enters
into a swap  agreement  on a net basis,  it will  segregate  assets with a daily
value at least equal to the  excess,  if any,  of a Fund's  accrued  obligations
under the swap  agreement  over the  accrued  amount  such Fund is  entitled  to
receive  under the  agreement.  If a Fund enters into a swap  agreement on other
than a net basis, it will segregate assets with a value equal to the full amount
of such Fund's accrued  obligations  under the agreement.  Presently,  each Fund
does not intend to invest more than 5% of its net assets in Swap Agreements.

INDEXED SECURITIES

     Each Fund may purchase securities whose prices are indexed to the prices of
other  securities,  securities  indexes,  currencies,  precious  metals or other
commodities,  or other financial indicators.  Indexed securities typically,  but
not always,  are debt  securities or deposits  whose value at maturity or coupon
rate  is  determined  by  reference  to  a  specific  instrument  or  statistic.
Gold-indexed  securities,  for example,  typically  provide for a maturity value
that depends on the price of gold,  resulting in a security whose price tends to
rise and fall together with gold prices.  Currency-indexed  securities typically
are short-term to  intermediate-term  debt  securities  whose maturity values or
interest  rates  are  determined  by  reference  to the  values  of one or  more
specified   foreign   currencies,   and  may  offer  higher   yields  than  U.S.
dollar-denominated securities of equivalent issuers. Currency-indexed securities
may be positively  or  negatively  indexed;  that is, their  maturity  value may
increase when the specified  currency value  increases,  resulting in a security
that performs similarly to a foreign-denominated  instrument,  or their maturity
value may decline  when  foreign  currencies  increase,  resulting in a security
whose price  characteristics  are similar to a put on the  underlying  currency.
Currency-indexed  securities may also have prices that depend on the values of a
number of different foreign currencies relative to each other.

     The  performance  of indexed  securities  depends to a great  extent on the
performance  of the security,  currency,  or other  instrument to which they are
indexed,  and may also be  influenced  by interest  rate changes in the U.S. and
abroad.  At the same time,  indexed  securities  are subject to the credit risks
associated  with the  issuer of the  security,  and  their  values  may  decline
substantially if the issuer's creditworthiness  deteriorates.  Recent issuers of
indexed  securities  have  included  banks,   corporations,   and  certain  U.S.
government  agencies.  IAI will use its judgment in determining  whether indexed
securities should be treated as short-term  instruments,  bonds, stocks, or as a
separate asset class for purposes of a Fund's investment policies,  depending on
the individual characteristics of the securities. Indexed securities may be more
volatile than the underlying instruments.  Presently,  each Fund does not intend
to invest more than 5% of its net assets in indexed securities.

LIMITATIONS ON FUTURES AND OPTIONS TRANSACTIONS

     Each  Fund  has  filed a  notice  of  eligibility  for  exclusion  from the
definition of the term  "commodity  pool  operator"  with the Commodity  Futures
Trading Commission (CFTC) and the National Futures  Association,  which regulate
trading in the futures  markets,  before  engaging in any  purchases or sales of
futures contracts or options on futures  contracts.  Each Fund intends to comply
with Section 4.5 of the  regulations  under the Commodity  Exchange  Act,  which
limits the extent to which a Fund can commit assets to initial  margin  deposits
and option premiums.

     In addition,  each Fund will not: (a) sell futures contracts,  purchase put
options,  or write call options if, as a result, more than 25% of a Fund's total
assets would be hedged with futures and options  under  normal  conditions;  (b)
purchase futures  contracts or write put options if, as a result, a Fund's total
obligations  upon  settlement  or exercise of purchased  futures  contracts  and
written put options would exceed 25% of its total  assets;  or (c) purchase call
options if, as a result,  the current value of option  premiums for call options
purchased  by a  Fund  would  exceed  5% of  such  Fund's  total  assets.  These
limitations do not apply to options  attached to or acquired or traded  together
with  their  underlying  securities,   and  do  not  apply  to  securities  that
incorporate features similar to options.

                                      -5-

     The above  limitations  on a Fund's  investments  in futures  contracts and
options,  and such  Fund's  policies  regarding  futures  contracts  and options
discussed  elsewhere in this Statement of Additional  Information may be changed
as regulatory agencies permit. With respect to positions in commodity futures or
commodity  option  contracts  which do not come within the meaning and intent of
bona fide hedging in the CFTC rules,  the aggregate  initial margin and premiums
required  to  establish  such  positions  will not  exceed  five  percent of the
liquidation  value of a Fund's portfolio,  after taking into account  unrealized
profits and unrealized  losses on any such  contracts it has entered into;  and,
provided  further,  that in the case of an  option  that is  in-the-money,  such
amount may be excluded in computing such five percent.


FUTURES CONTRACTS

     When a Fund purchases a futures contract, it agrees to purchase a specified
underlying  instrument at a specified  future date.  When a Fund sells a futures
contract,  it agrees to sell the  underlying  instrument  at a specified  future
date.  The price at which the  purchase and sale will take place is fixed when a
Fund enters into the contract.  Some currently  available  futures contracts are
based on specific securities, such as U.S. Treasury bonds or notes, and some are
based on  indexes  of  securities  prices,  such as the  Standard  & Poor's  500
Composite Stock Price Index (S&P 500).  Futures can be held until their delivery
dates,  or can be  closed  out  before  then if a  liquid  secondary  market  is
available.

     The value of a futures  contract  tends to increase  and decrease in tandem
with the  value of its  underlying  instrument.  Therefore,  purchasing  futures
contracts will tend to increase a Fund's exposure to positive and negative price
fluctuations  in the  underlying  instrument,  much as if it had  purchased  the
underlying  instrument  directly.  When a Fund  sells  a  futures  contract,  by
contrast,  the value of its  futures  position  will tend to move in a direction
contrary to the  market.  Selling  futures  contracts,  therefore,  will tend to
offset  both  positive  and  negative  market  price  changes,  much  as if  the
underlying instrument had been sold.

FUTURES MARGIN PAYMENTS

     The purchaser or seller of a futures contract is not required to deliver or
pay for the underlying instrument unless the contract is held until the delivery
date.  However,  both the purchaser and seller are required to deposit  "initial
margin" with a futures  broker,  known as a futures  commission  merchant (FCM),
when the contract is entered into.  Initial margin  deposits are typically equal
to a percentage of the contract's value. If the value of either party's position
declines,  that party will be required  to make  additional  "variation  margin"
payments  to settle the change in value on a daily  basis.  The party that has a
gain may be  entitled to receive  all or a portion of this  amount.  Initial and
variation margin payments do not constitute  purchasing securities on margin for
purposes of a Fund's investment  limitations.  In the event of the bankruptcy of
an FCM that  holds  margin  on behalf of a Fund,  such Fund may be  entitled  to
return of margin  owed to it only in  proportion  to the amount  received by the
FMC's other customers, potentially resulting in losses to such Fund.

PURCHASING PUT AND CALL OPTIONS

     By  purchasing  a put  option,  a Fund  obtains  the  right  (but  not  the
obligation) to sell the option's underlying  instrument at a fixed strike price.
In return for this right,  a Fund pays the current  market  price for the option
(known  as the  option  premium).  Options  have  various  types  of  underlying
instruments,  including specific  securities,  indexes of securities prices, and
futures  contracts.  A Fund may  terminate  its  position in a put option it has
purchased by allowing it to expire or by exercising the option. If the option is
allowed  to  expire,  a Fund will lose the  entire  premium  it paid.  If a Fund
exercises the option, it completes the sale of the underlying  instrument at the
strike price. A Fund may also terminate a put option  position by closing it out
in the  secondary  market at its current  price,  if a liquid  secondary  market
exists.

     The buyer of a typical  put option can expect to realize a gain if security
prices fall substantially.  However,  if the underlying  instrument's price does
not fall enough to offset the cost of  purchasing  the  option,  a put buyer can
expect to suffer a loss (limited to the amount of the premium paid, plus related
transaction costs).

                                      -6-
<PAGE>


     The  features  of call  options  are  essentially  the same as those of put
options,  except  that the  purchaser  of a call  option  obtains  the  right to
purchase,  rather than sell,  the underlying  instrument at the option's  strike
price.  A call buyer  typically  attempts  to  participate  in  potential  price
increases  of the  underlying  instrument  with risk  limited to the cost of the
option if security prices fall. At the same time, the buyer can expect to suffer
a loss if  security  prices do not rise  sufficiently  to offset the cost of the
option.

WRITING PUT AND CALL OPTIONS

     When a Fund  writes  a put  option,  it  takes  the  opposite  side  of the
transaction from the option's  purchaser.  In return for receipt of the premium,
such Fund  assumes  the  obligation  to pay the  strike  price for the  option's
underlying  instrument if the other party to the option  chooses to exercise it.
When  writing an option on a futures  contract a Fund would be  required to make
margin payments to an FCM as described above for futures  contracts.  A Fund may
seek to  terminate  its  position in a put option it writes  before  exercise by
closing  out the option in the  secondary  market at its current  price.  If the
secondary  market is not liquid for a put  option a Fund has  written,  however,
such Fund must  continue to be prepared to pay the strike price while the option
is  outstanding,  regardless  of price  changes,  and must continue to set aside
assets to cover its  position.  If  security  prices  rise,  a put writer  would
generally expect to profit,  although its gain would be limited to the amount of
the premium it received.

     If security  prices remain the same over time, it is likely that the writer
will also  profit,  because it should be able to close out the option at a lower
price.  If security  prices fall,  the put writer would expect to suffer a loss.
This loss should be less than the loss from purchasing the underlying instrument
directly,  however,  because the premium  received for writing the option should
mitigate the effects of the decline.

     Writing a call  option  obligates  a Fund to sell or deliver  the  option's
underlying  instrument,  in return for the strike  price,  upon  exercise of the
option.  The  characteristics  of writing  call  options are similar to those of
writing put  options,  except  that  writing  calls  generally  is a  profitable
strategy  if prices  remain  the same or fall.  Through  receipt  of the  option
premium,  a call writer  mitigates the effects of a price  decline.  At the same
time,  because  a call  writer  must  be  prepared  to  deliver  the  underlying
instrument in return for the strike price, even if its current value is greater,
a call writer gives up some ability to participate in security price increases.

COMBINED POSITIONS

     A Fund may purchase and write options in combination with each other, or in
combination  with  futures or forward  contracts,  to adjust the risk and return
characteristics of the overall position.  For example, a Fund may purchase a put
option and write a call option on the same  underlying  instrument,  in order to
construct a combined position whose risk and return  characteristics are similar
to selling a futures contract.  Another possible combined position would involve
writing a call  option at one strike  price and buying a call  option at a lower
price,  in order to reduce the risk of the written call option in the event of a
substantial price increase.  Because combined options positions involve multiple
trades,  they result in higher  transaction  costs and may be more  difficult to
open and close out.

CORRELATION OF PRICE CHANGES

     Because there are a limited number of types of exchange-traded  options and
futures contracts,  it is likely that the standardized  contracts available will
not match a Fund's  current or  anticipated  investments  exactly.  The Fund may
invest in options and  futures  contracts  based on  securities  with  different
issuers,  maturities,  or other  characteristics from the securities in which it
typically  invests,  which involves a risk that the options or futures  position
will not track the performance of such Fund's other investments.

                                      -7-
<PAGE>


     Options  and  futures  prices  can also  diverge  from the  prices of their
underlying  instruments,  even if the  underlying  instruments  match  a  Fund's
investments  well.  Options and futures  prices are  affected by such factors as
current and anticipated  short-term interest rates, changes in volatility of the
underlying instrument,  and the time remaining until expiration of the contract,
which may not affect  security  prices the same way.  Imperfect  correlation may
also result from differing  levels of demand in the options and futures  markets
and the  securities  markets,  from  structural  differences  in how options and
futures and securities are traded, or from imposition of daily price fluctuation
limits or  trading  halts.  A Fund may  purchase  or sell  options  and  futures
contracts  with a greater or lesser value than the securities it wishes to hedge
or intends to  purchase in order to attempt to  compensate  for  differences  in
volatility  between the contract and the  securities,  although  this may not be
successful  in all  cases.  If price  changes  in a Fund's  options  or  futures
positions are poorly  correlated with its other  investments,  the positions may
fail to  produce  anticipated  gains or result in losses  that are not offset by
gains in other investments.

LIQUIDITY OF OPTIONS AND FUTURES CONTRACTS

     There  is no  assurance  a  liquid  secondary  market  will  exist  for any
particular  options or futures contract at any particular time. Options may have
relatively low trading volume and liquidity if their strike prices are not close
to the  underlying  instrument's  current  price.  In  addition,  exchanges  may
establish daily price fluctuation limits for options and futures contracts,  and
may halt  trading if a contract's  price moves upward or downward  more than the
limit in a given day. On volatile trading days when the price  fluctuation limit
is reached or a trading  halt is  imposed,  it may be  impossible  for a Fund to
enter into new  positions  or close out  existing  positions.  If the  secondary
market for a  contract  is not liquid  because  of price  fluctuation  limits or
otherwise,  it could prevent prompt  liquidation of unfavorable  positions,  and
potentially  could require a Fund to continue to hold a position  until delivery
or expiration  regardless of changes in its value. As a result,  a Fund's access
to other  assets  held to cover its options or futures  positions  could also be
impaired.

OTC OPTIONS

     Unlike exchange-traded  options, which are standardized with respect to the
underlying  instrument,  expiration  date,  contract size, and strike price, the
terms of  over-the-counter  options (options not traded on exchanges)  generally
are established through negotiation with the other party to the option contract.
While this type of  arrangement  allows a Fund greater  flexibility to tailor an
option to its needs,  OTC options  generally  involve  greater  credit risk than
exchange-traded  options,  which are guaranteed by the clearing  organization of
the exchanges where they are traded.

ASSET COVERAGE FOR FUTURES AND OPTIONS POSITIONS

     Each Fund will comply with  guidelines  established  by the  Securities and
Exchange  Commission with respect to coverage of options and futures  strategies
by mutual funds,  and if the  guidelines  so require will set aside  appropriate
liquid  assets in a  segregated  custodial  account  in the  amount  prescribed.
Securities  held in a  segregated  account  cannot be sold while the  futures or
option  strategy is  outstanding,  unless they are replaced with other  suitable
assets.  As a  result,  there  is a  possibility  that  segregation  of a  large
percentage  of a Fund's  assets could impede  portfolio  management  or a Fund's
ability to meet redemption requests or other current obligations.

ECONOMIES OF THE UNITED KINGDOM AND GERMANY

     As discussed in the  Prospectus,  International  Fund may from time to time
concentrate  more than 25% of its total  assets in the  economy  of Japan.  This
section includes a general discussion of the economies of the United Kingdom and
Germany. The economy of Japan is further described in the Prospectus.

     UNITED  KINGDOM.  The  United  Kingdom  is a  constitutional  monarchy  and
consists of England, Scotland, Wales and Northern Ireland. The population of the
United Kingdom is  approximately  57 million.  Industry in the United Kingdom is
predominantly  owned in the  private  sector  except  for  certain  state  owned
entities in the transportation and energy industries.

                                      -8-
<PAGE>

     The  financial  center of the United  Kingdom is London,  which is also the
location  of the London  Stock  Exchange.  In October  of 1986,  stock  exchange
commission rates were deregulated and stock exchange membership was opened up to
limited companies and to non-residents of the United Kingdom.  Additionally, the
Financial  Services  Act  (the  "FSA")   substantially   restructured  the  U.K.
securities  laws and  deregulated  the London Stock  Exchange's  own rules.  FSA
created a new regulatory body known as the Securities and Investments Board (the
"SIB"),  which has the power to  delegate  certain of its  functions  to various
self-regulatory organizations,  of which the London Stock Exchange is one. Under
the FSA  structure,  the  London  Stock  Exchange  will  continue  to be largely
self-regulating  with fundamentally the same types of  self-regulatory  rules in
effect prior to FSA.

     Stock prices are  continuously  quoted during  business hours on the London
Stock  Exchange,  and are  negotiable,  but have  formalized  for  institutions.
Trading commissions in the U.K. are negotiable.

     Securities  in the United  Kingdom  are  denominated  and quoted in "pounds
sterling".  Pounds  sterling are fully  convertible  and  transferable  based on
floating  exchange rates into all currencies,  without  administrative  or legal
restrictions, for both non-residents and residents of the United Kingdom.

     GERMANY. Germany is a federated republic with a population of approximately
80 million and a democratic parliamentary form of government. The German economy
is organized primarily on the basis of private sector ownership,  with the state
exerting  major  influence  through  ownership  in  certain  sectors,  including
transportation,  communication and energy.  Unification of West Germany with the
formerly communist controlled East Germany took place in 1990.

     Industrial  activity  makes the largest  contribution  to the German  gross
national  product.  Although  only  5%  of  German  businesses  are  large-scale
enterprises,  such  large-scale  businesses  account for over half of industrial
production  and employ over half the  industrial  labor force.  Trading  volume,
therefore,  tends to  concentrate  on relatively  few companies  with both large
capitalizations  and broad stock ownership.  Historically the German economy has
been strongly export oriented.  Privatization of formerly state owned enterprise
in what was once East Germany is in progress, but will make little difference to
the  predominance of large scale businesses in overall  industrial  activity and
the stock market.

     German  equity  securities  trade  predominantly  on  the  country's  eight
independent local stock exchanges,  the Frankfurt exchange accounting for 70% of
turnover.  Subject to the  provisions of pertinent  securities  law,  mainly the
Stock  Exchange  Law of 1896,  as amended,  the  council,  management  and other
executive  organs  of the  stock  exchanges  constitute  self-administering  and
self-regulatory   bodies.   The  "Working  Group  of  German  Stock   Exchanges"
headquartered  in  Frankfurt,  of which all eight stock  exchanges  are members,
addresses all policy and administrative  questions of national and international
character.

     Prices for active stocks,  including those for larger  companies are quoted
continuously during stock exchange hours. Less actively traded stocks are quoted
only once a day. Equity shares are normally fully-paid and non-assessable.

     Orders for stock  executed for large  customers on the stock  exchanges are
negotiable.  A federal  stock  exchange  turnover tax,  ranging up to 0.25%,  is
levied on all securities  transactions  other than those between banks acting as
principal. Nonresidents such as the Fund are charged half these rates.

     German equity securities are denominated in Deutchemarks.  Deutchemarks are
fully convertible and transferable into all currencies,  without  administrative
or legal  restrictions,  for both  nonresidents and residents of Germany.  Since
1974, the Deutchemark  has traded on a floating  exchange rate basis against all
currencies.

NO RATING CRITERIA FOR DEBT SECURITIES

     Developing  Countries Fund has  established no rating criteria for the debt
securities  in which it may invest.  Therefore,  Developing  Countries  Fund may
invest  in debt  securities  either  (a)  which are rated in one of the top four
rating  categories  by a  nationally  recognized  rating  organization  or which
possess similar credit  characteristics  ("investment  grade securities") or (b)
which are rated below the top four rating  categories or which  possess  similar
credit  characteristics  ("high yield  securities").  Ratings are one of several
factors utilized in performing a credit analysis of issuers.

     Issuers of high yield  securities may be highly  leveraged and may not have
available to them more traditional  methods of financing.  Therefore,  the risks
associated  with acquiring the securities of such issuers  generally are greater
than is the case with higher rated securities.  For example,  during an economic
downturn or a sustained  period of rising interest rates,  issuers of high yield
securities may be more likely to experience financial stress, especially if such
issuers are highly  leveraged.  During such  periods,  such issuers may not have
sufficient  revenues to meet their interest  payment  obligations.  The issuer's
ability  to service  its debt  obligations  also may be  adversely  affected  by
specific  issuer  developments  or  the  issuer's  inability  to  meet  specific
projected business forecasts or the unavailability of additional financing.  The
risk of loss due to  default  by the  issuer is  significantly  greater  for the
holders of high yield  securities  because such  securities may be unsecured and
may be subordinated to other creditors of the issuer.

     High yield  securities  frequently  have call or redemption  features which
would permit an issuer to repurchase  the security from the Fund. If a call were
exercised by the issuer during a period of declining  interest  rates,  the Fund
likely  would  have to  replace  such  called  security  with a  lower  yielding
security, thus decreasing the net investment income to the Fund and dividends to
shareholders.

     Developing  Countries  Fund may have  difficulty  disposing of certain high
yield securities because there may be a thin trading market for such securities.
The  secondary  trading  market for high yield  securities  is generally  not as
liquid as the secondary market for higher rated  securities.  Reduced  secondary
market  liquidity  may have an  adverse  impact on market  price and  Developing
Countries Fund's ability to dispose of particular  issues when necessary to meet
Developing  Countries  Fund's  liquidity  needs  or in  response  to a  specific
economic event such as a deterioration in the creditworthiness of the issuer.

     Adverse  publicity  and  investor  perceptions,  which  may not be based on
fundamental  analysis,  also may decrease the value and  liquidity of high yield
securities,  particularly in a thinly traded market. Factors adversely affecting
the  market  value of high  yield  securities  are  likely to  adversely  affect
Developing  Countries  Fund's net asset value.  In addition,  the Fund may incur
additional expenses to the extent it is required to seek recovery upon a default
on a portfolio holding or participate in the restructuring of the obligation.

ADDITIONAL RISK CONSIDERATIONS

     Investors  should consider  carefully the  substantial  risks involved with
respect to  investing in  securities  of companies  and  governments  of foreign
nations,  which  are in  addition  to  the  usual  risks  inherent  in  domestic
investments. Such risks are heightened with respect to investments in developing
countries.  There  may be less  publicly  available  information  about  foreign
companies comparable to the reports and ratings published about companies in the
United  States.   Foreign   companies  are  not  generally  subject  to  uniform
accounting,  auditing and financial reporting standards,  and auditing practices
and  requirements  may not be  comparable  to those  applicable to United States
companies. Foreign markets typically have substantially less volume than the New
York Stock Exchange and securities of some foreign companies are less liquid and
more volatile than securities of comparable United States companies.  Commission
rates in foreign  countries,  which are  generally  fixed rather than subject to
negotiation  as in the United States,  are likely to be higher.  In many foreign
countries  there  is  less  government   supervision  and  regulation  of  stock
exchanges, brokers and listed companies than in the United States.

                                      -10-
<PAGE>

     Investments in developing  countries may be subject to  potentially  higher
risks than  investments  in developed  countries.  These risks  include (i) less
social,  political  and economic  stability;  (ii) the small current size of the
markets for such  securities  and the  currently  low or  nonexistent  volume of
trading,  which  may  result  in a  lack  of  liquidity  and  in  greater  price
volatility;  (iii)  certain  national  policies  which may  restrict  the Fund's
investment  opportunities,  including  restrictions  on investment in issuers or
industries deemed sensitive to national  interests;  (iv) foreign taxation;  (v)
the absence of developed  structures  governing private or foreign investment or
allowing for judicial redress for injury to private  property;  (vi) the limited
development  and recent  emergence,  in certain  countries,  of a capital market
structure or  market-oriented  economy;  and (vii) the  possibility  that recent
favorable  economic  developments in certain countries may be slowed or reversed
by unanticipated political or social events in such countries.

     Despite the recent dissolution of the Soviet Union, the Communist Party may
continue  to  exercise  a  significant  role in  certain  (particularly  Eastern
European)  countries.   To  the  extent  of  the  Communist  Party's  influence,
investments   in  such   countries   will  involve  risks  of   nationalization,
expropriation and confiscatory  taxation.  The communist governments of a number
of such countries expropriated large amounts of private property in the past, in
many cases without  adequate  compensation,  and there can be no assurance  that
such  expropriation  will  not  occur  in the  future.  In  the  event  of  such
expropriation, a Fund could lose a substantial portion of any investments it has
made in the affected countries.  Further, no accounting  standards exist in many
developing countries. Finally, even though certain currencies may be convertible
into U.S.  dollars,  the conversion rates may be artificial to the actual market
values and may be adverse to Fund shareholders.

     Certain countries, which do not have market economies, are characterized by
an  absence  of  developed  legal  structures   governing  private  and  foreign
investments  and  private  property.   Certain  countries  require  governmental
approval  prior to  investments  by  foreign  persons,  or limit  the  amount of
investment by foreign persons in a particular  company,  or limit the investment
of foreign  persons to only a specific class of securities of a company that may
have less  advantageous  terms than  securities  of the  company  available  for
purchase by nationals.

     Authoritarian   governments  in  certain   countries  may  require  that  a
governmental  or  quasi-governmental  authority  to act as custodian of a Fund's
assets   invested  in  such  country.   To  the  extent  such   governmental  or
quasi-governmental  authorities do not satisfy the  requirements of the 1940 Act
to act as  foreign  custodians  of the  Fund's  cash  and  securities,  a Fund's
investment  in such  countries  may be limited or may be required to be effected
through intermediaries.  The risk of loss through governmental  confiscation may
be increased in such countries.

     A Fund endeavors to buy and sell foreign currencies on as favorable a basis
as  practicable.  Some  price  spread on  currency  exchange  (to cover  service
charges) may be incurred,  particularly when a Fund changes investments from one
country to another or when proceeds from the sale of shares in U.S.  dollars are
used for the purchase of securities in foreign  countries.  Also, some countries
may adopt policies which would prevent a Fund from  transferring cash out of the
country,  withhold  portions of interest and dividends at the source,  or impose
other taxes,  with respect to a Fund's  investments  in securities of issuers of
that country. Although a Fund invests only in foreign nations which it considers
as having relatively stable and friendly  governments,  there is the possibility
of  expropriation,  nationalization,  confiscatory  or other  taxation,  foreign
exchange  controls  (which may  include  suspension  of the  ability to transfer
currency  from a given  country),  default  in  foreign  government  securities,
political or social  instability  or diplomatic  developments  that could affect
investments in securities of issuers in those nations.

     A Fund may be affected  either  unfavorably or favorably by fluctuations in
the relative rates of exchange between the currencies of different  nations,  by
exchange   control   regulations  and  by  indigenous   economic  and  political
developments.  Through a Fund's flexible policy,  management  endeavors to avoid
unfavorable  consequences  and to take  advantage of favorable  developments  in
particular nations where from time to time it places a Fund's investments.

                                      -11-
<PAGE>

     The  exercise of this  flexible  policy may include  decisions  to purchase
securities with  substantial  risk  characteristics  and other decisions such as
changing  the  emphasis on  investments  from one nation to another and from one
type of security to another.  Some of these decisions may later prove profitable
and others may not. No assurance can be given that profits,  if any, will exceed
losses.  However,  in the  absence  of willful  misfeasance,  bad faith or gross
negligence on the part of the investment manager,  any losses resulting from the
holding of a Fund's  portfolio  securities  in  foreign  countries  and/or  with
securities depositories will be at the risk of the shareholders.

     A Fund's  ability to reduce or  eliminate  its futures and related  options
positions  will  depend upon the  liquidity  of the  secondary  markets for such
futures and  options.  Each Fund intends to purchase or sell futures and related
options only on exchanges or boards of trade where there appears to be an active
secondary market,  but there is no assurance that a liquid secondary market will
exist for any particular  contract or at any particular time. Use of stock index
futures and related  options for hedging may involve  risks because of imperfect
correlations  between  movements in the prices of the futures or related options
and movements in the prices of the  securities  being hedged.  Successful use of
futures and related options by a Fund for hedging purposes also depends upon the
investment  manager's ability to predict correctly movements in the direction of
the market, as to which no assurance can be given.


                             INVESTMENT RESTRICTIONS

     As indicated in the  Prospectus,  each Fund is subject to certain  policies
and  restrictions  which  are  "fundamental"  and  may  not be  changed  without
shareholder  approval.  Shareholder  approval  consists  of the  approval of the
lesser of (i) more than 50% of the outstanding  voting  securities of a Fund, or
(ii) 67% or more of the voting securities present at a meeting if the holders of
more than 50% of the  outstanding  voting  securities of the Fund are present or
represented  by proxy.  Limitations  1 through  8 below are  deemed  fundamental
limitations.  The  remaining  limitations  set forth  below  serve as  operating
policies  of each  Fund and may be  changed  by the Board of  Directors  without
shareholder approval.

     Each Fund may not:

     1. Purchase the  securities of any issuer if such purchase  would cause the
Fund to fail to meet the  requirements  of a  "diversified  company"  as defined
under the Investment Company Act of 1940, as amended (the "1940 Act").

     As  defined  in the 1940  Act,  "diversified  company"  means a  management
company  which meets the following  requirements:  at least 75 per centum of the
value of its  total  assets is  represented  by cash and cash  items  (including
receivables),  Government securities,  securities of other investment companies,
and other securities for the purposes of this calculation  limited in respect of
any one issuer to an amount not  greater in value than 5 per centum of the value
of the total assets of such  management  company and not more than 10 per centum
of the outstanding voting securities of such issuer.

     2.  Purchase  the   securities  of  any  issuer  (other  than   "Government
securities" as defined under the 1940 Act) if, as a result, more than 25% of the
value  of the  Fund's  total  assets  would be  invested  in the  securities  of
companies whose principal business activities are in the same industry.

     For  purposes  of  applying  this  restriction,  a Fund  will not  purchase
securities,  as defined above,  such that 25% or more of the value of the Fund's
total  assets are  invested  in the  securities  of  companies  whose  principal
business activities are in the same industry.

     3. Issue any senior securities,  except as permitted by the 1940 Act or the
Rules and Regulations of the Securities and Exchange Commission.

     4. Borrow  money,  except from banks for  temporary or  emergency  purposes
provided that such  borrowings may not exceed 33-1/3% of the value of the Fund's
net assets (including the amount  borrowed).  Any borrowings that come to exceed
this  amount  will be reduced  within  three  days (not  including  Sundays  and
holidays) to the extent  necessary to comply with the 33-1/3%  limitation.  This
limitation  shall not  prohibit  the Fund from  engaging  in reverse  repurchase
agreements,  making  deposits  of assets to margin  or  guarantee  positions  in
futures,   options,  swaps  or  forward  contracts,  or  segregating  assets  in
connection with such agreements or contracts.

     To the extent a Fund engages in reverse repurchase agreements, because such
transactions  are  considered  borrowing,   reverse  repurchase  agreements  are
included in the 33-1/3% limitation.

     5. Act as an  underwriter  of  securities of other  issuers,  except to the
extent that in connection with the disposition of portfolio  securities the Fund
may be deemed to be an underwriter under applicable laws.

     6. Purchase or sell real estate unless acquired as a result of ownership of
securities or other  instruments.  This  restriction  shall not prevent the Fund
from  investing  in  securities  or other  instruments  backed by real estate or
securities of companies engaged in the real estate business.

     7. Purchase or sell  physical  commodities  unless  acquired as a result of
ownership of  securities  or other  instruments  (but this shall not prevent the
Fund from purchasing or selling  options and future  contracts or from investing
in securities or other instruments backed by physical commodities).

     For purposes of applying this restriction, "commodities" shall be deemed to
include commodity contracts.

     8. Make loans to other persons except to the extent not  inconsistent  with
the 1940  Act or the  Rules  and  Regulations  of the  Securities  and  Exchange
Commission.  This  limitation  does not apply to purchases of commercial  paper,
debt  securities  or  repurchase  agreements,  or to the  lending  of  portfolio
securities.

     9.  Purchase  securities  on margin,  except  that the Fund may obtain such
short-term  credits as may be necessary  for the clearance of purchases or sales
of securities and provided that margin payments in connection with  transactions
in  options,  futures,  swaps  and  forward  contracts  shall  not be  deemed to
constitute purchasing securities on margin.

     10.  Sell  securities  short,  unless  it owns or has the  right to  obtain
securities  equivalent  in kind and amount to the  securities  sold  short,  and
provided that  transactions in options,  swaps and forward futures contracts are
not deemed to constitute selling securities short.

     For purposes of applying this restriction,  a Fund will not sell securities
short  except to the extent that it  contemporaneously  owns or has the right to
obtain, at no added cost, securities identical to those sold short.

     11.   Except  as  part  of  a  merger,   consolidation,   acquisition,   or
reorganization,  invest  more than 5% of the  value of its  total  assets in the
securities  of any one  investment  company or more than 10% of the value of its
total assets,  in the  aggregate,  in the  securities of two or more  investment
companies, or acquire more than 3% of the total outstanding voting securities of
any one investment company.

     12.  Mortgage,  pledge or  hypothecate  its  assets  except  to the  extent
necessary to secure  permitted  borrowings.  This  limitation  does not apply to
reverse  repurchase  agreements or in the case of assets  deposited to margin or
guarantee positions in futures, options, swaps or forward contracts or placed in
a segregated account in connection with such contracts.

     13.  Participate  on a joint or a joint and several basis in any securities
trading account.

                                      -13-

     14.  Developing  Countries  Fund may not  invest  more  than 10% of its net
assets in illiquid investments.  International Fund may not invest more than 15%
of its net assets in illiquid investments.

     15. Invest directly in interests (including  partnership interests) in oil,
gas or other mineral  exploration or development leases or programs,  except the
Fund may purchase or sell securities issued by corporations engaging in oil, gas
or other mineral exploration or development business.

     Any of the Fund's investment policies set forth under "Investment Objective
and  Policies"  in the  Prospectus,  or any  restriction  set forth  above under
"Investment  Restrictions"  which involves a maximum percentage of securities or
assets (other than  Restriction 4) shall not be considered to be violated unless
an  excess  over the  percentage  occurs  immediately  after an  acquisition  of
securities  or  utilization  of assets and results  therefrom.  With  respect to
Restriction  14, a Fund is under a continuing  obligation to ensure that it does
not violate  the  maximum  percentage  either by  acquisition  or by virtue of a
decrease in the value of the Fund's liquid assets.

PORTFOLIO TURNOVER

     The  portfolio  turnover  rate is  calculated  by  dividing  the  lesser of
purchases or sales of portfolio securities for the particular fiscal year by the
monthly  average of the value of portfolio  securities  owned by the Fund during
the same fiscal year. "Portfolio securities" for purposes of this calculation do
not include securities with a maturity date of less than twelve (12) months from
the date of investment. A 100% portfolio turnover rate would occur, for example,
if the lesser of the value of purchases or sales of portfolio  securities  for a
particular  year  were  equal to the  average  monthly  value  of the  portfolio
securities  owned during such year.  The Funds'  historical  portfolio  turnover
rates are set forth in the prospectus section "Financial Highlights".


                             INVESTMENT PERFORMANCE

     Advertisements  and  other  sales  literature  for each  Fund may  refer to
monthly,  quarterly,  yearly,  cumulative and average annual total return.  Each
such  calculation  assumes all  dividends  and capital  gain  distributions  are
reinvested at net asset value on the appropriate reinvestment dates as described
in the Prospectus,  and includes all recurring fees, such as investment advisory
and management fees,  charged as expenses to all shareholder  accounts.  Each of
monthly,  quarterly  and yearly  total  return is computed in the same manner as
cumulative total return, as set forth below.

     Cumulative  total  return is  computed by finding  the  cumulative  rate of
return over the period  indicated  in the  advertisement  that would  equate the
initial  amount  invested  to the  ending  redeemable  value,  according  to the
following formula:

            CTR = (ERV-P) 100
                   -----
                     P

   Where:  CTR  =  Cumulative total return;

           ERV  =  ending redeemable value at the end of the period of a 
                   hypothetical $1,000 payment made at the beginning of 
                   such period; and

             P  =  initial payment of $1,000

     Average  annual  total  return is computed  by finding  the average  annual
compounded rates of return over the periods indicated in the advertisement  that
would  equate  the  initial  amount  invested  to the ending  redeemable  value,
according to the following formula:

                                      -14-
<PAGE>

                 P(1+T)n = ERV

   Where:   P   =  a hypothetical initial payment of $1,000;

            T   =  average annual total return;

            n   =  number of years; and

          ERV   =  ending redeemable value at the end of the
                   period of a hypothetical $1,000 payment made 
                   at the beginning of such period.

The table  below  shows the yearly  total  return for the Funds for the  periods
indicated.

     The average  annual  return of Developing  Countries  Fund for the one year
period  ended  January 31, 1997 and from  February  10,  1995  (commencement  of
operations) through January 31, 1997 was 5.22 and 6.95%, respectively.

     The average annual return of  International  Fund for the one and five year
periods  ended  January  31,  1997 and from  April  23,  1987  (commencement  of
operations) through January 31, 1997 was 2.39%, 8.47% and 7.34%, respectively.

     In advertising and sales literature,  each Fund may compare its performance
with that of other  mutual  funds,  indexes or averages of other  mutual  funds,
indexes of related financial assets or data, and other competing  investment and
deposit  products  available from or through other financial  institutions.  The
composition of these indexes,  averages or products differs from that of a Fund.
The  comparison  of a Fund to an  alternative  investment  should  be made  with
consideration  of differences in features and expected  performance.  A Fund may
also note its  mention in  newspapers,  magazines,  or other  media from time to
time. However, a Fund assumes no responsibility for the accuracy of such data.

     For example,  (1) a Fund's  performance or P/E ratio may be compared to any
one or a combination of the following: (i) the Standard & Poor's 500 Stock Index
and Dow Jones  Industrial  Average so that you may compare a Fund's results with
those of a group  of  unmanaged  securities  widely  regarded  by  investors  as
representative of the U.S. stock market in general;  (ii) other groups of mutual
funds,  including  the IAI Funds,  tracked by: (A) Lipper  Analytical  Services,
Inc.,  a widely  used  independent  research  firm which ranks  mutual  funds by
overall performance,  investment objectives, and assets; (B) Morningstar,  Inc.,
another widely used  independent  research firm which rates mutual funds; or (C)
other financial or business publications, which may include, but are not limited
to, Business Week,  Money Magazine,  Forbes and Barron's,  which provide similar
information;  (iii) The Financial Times (a London based international  financial
newspaper)-Actuaries  World Indices, including Europe and 


                                       -15-
<PAGE>

sub-indices  comprising  this Index (a wide range of  comprehensive  measures of
stock price  performance  for the major stock  markets,  as well as for regional
areas, broad economic sectors and industry groups);  (iv) Morgan Stanley Capital
International  Indices,  including  the EAFE  Index;  (v)  Baring  International
Investment  Management Limited (an international  securities trading,  research,
and investment management firm), as a source for market capitalization,  GDP and
GNP; (vi) the International  Finance Corporation (an affiliate of the World Bank
established to encourage  economic  development  in less  developed  countries),
World Bank, OECD  (Organization  for Economic  Co-Operation and Development) and
IMF (International  Monetary Fund) as a source of economic statistics;  and (ix)
the performance of U.S.  government and corporate bonds,  notes and bills.  (The
purpose  of  these  comparisons  would be to  illustrate  historical  trends  in
different market sectors so as to allow potential investors to compare different
investment  strategies.);  (2) the Consumer  Price Index (measure for inflation)
may be used to assess the real rate of return from an investment in a Fund;  (3)
other U.S.  or foreign  government  statistics  such as GNP,  and net import and
export  figures  derived from  governmental  publications,  e.g.,  The Survey of
Current Business,  may be used to illustrate  investment attributes of a Fund or
the general economic business,  investment,  or financial environment in which a
Fund operates; (4) the effect of tax-deferred compounding on a Fund's investment
returns,  or on returns in general,  may be illustrated by graphs,  charts, etc.
where such graphs or charts would compare, at various points in time, the return
from an  investment  in a Fund (or returns in general) on a  tax-deferred  basis
(assuming  reinvestment  of capital gains and dividends and assuming one or more
tax rates) with the return on a taxable basis; and (5) the sectors or industries
in which a Fund  invests may be compared to relevant  indices or surveys  (e.g.,
S&P Industry  Surveys) in order to evaluate a Fund's  historical  performance or
current or potential value with respect to the particular industry or sector.

The Code permits  access persons to engage in personal  securities  transactions
subject to certain  policies and procedures.  Such procedures  prohibit  certain
persons from  acquiring of any  securities  in an initial  public  offering.  In
addition,  securities  acquired  through private  placement must be pre-cleared.
Procedures have been adopted which would implement  blackout periods for certain
securities, as well as a ban on short-term trading profits.  Additional policies
prohibit  the  receipt  of gifts in  certain  instances.  Procedures  have  been
implemented  to monitor  employee  trading.  Each  access  person is required to
certify  annually  that they have read and  understood  the Code of  Ethics.  An
annual report is provided to the Funds' Board of Directors  summarizing existing
procedures and changes,  identifying  material  violations and  recommending any

HISTORY

     Each Fund is a separate  portfolio  of IAI  Investment  Funds III,  Inc., a
Minnesota  corporation  whose shares of common stock are currently issued in two
series (Series A and B). The investment portfolio represented by Series A common
shares is  referred to as "IAI  International  Fund." The  investment  portfolio
represented  by  Series  B  common  shares  is  referred  to as "IAI  Developing
Countries Fund." On June 25, 1993,  International  Fund's shareholders  approved
amended  and  restated  Articles  of  Incorporation,  which  provided  that  the
registered  investment  company whose corporate name had been IAI  International
Fund, Inc. be renamed "IAI Investment Funds III, Inc."

MANAGEMENT AGREEMENT

     Effective April 1, 1996,  pursuant to a Management  Agreement  between each
Fund  and  IAI,  IAI  agreed  to  provide  each  Fund  with  investment  advice,
statistical  and  research  facilities,  and  certain  equipment  and  services,
including,  but not limited to,  office space and necessary  office  facilities,
equipment,  and the services of required personnel and, in connection therewith,
IAI has the sole  authority and  responsibility  to make and execute  investment
decisions  for each Fund within the framework of a Fund's  investment  policies,
subject to review by the directors of a Fund. In addition, IAI agreed to provide
or arrange for the  provision of all required  administrative,  stock  transfer,
redemption, dividend disbursing, accounting, and shareholder services including,
without  limitation,  the following:  (1) the maintenance of a Fund's  accounts,
books  and  records;  (2) the  calculations  of the  daily  net  asset  value in
accordance  with  a  Fund's  current  Prospectus  and  Statement  of  Additional
Information;  (3) daily and periodic reports;  (4) all information  necessary to
complete tax returns,  questionnaires and other reports requested by a Fund; (5)
the  maintenance  of stock  registry  records;  (6) the  processing of requested
account  registration  changes,   stock

certificate  issuances  and  redemption  requests;  (7)  the  administration  of
payments and  dividends  and  distributions  declared by a Fund;  (8)  answering
shareholder  questions,  (9) providing  reports and other  information  and (10)
other  services  designed to  maintain  shareholder  accounts.  IAI may also pay
qualifying  broker-dealers,  financial  institutions  and  other  entities  that
provide such services. In return for these services, each Fund has agreed to pay
IAI an annual fee as a percentage of the Fund's  average daily net assets as set
forth below:

     Under the Management Agreement,  except for brokerage commissions and other
expenditures in connection  with the purchase and sale of portfolio  securities,
interest  expense,  and,  subject to the specific  approval of a majority of the
disinterested  directors of a Fund, taxes and  extraordinary  expenses,  IAI has
agreed to pay all of a Fund's other costs and expenses,  including, for example,
costs  incurred  in the  purchase  and sale of  assets,  taxes,  charges  of the
custodian of a Fund's  assets,  costs of reports and proxy material sent to Fund
shareholders,  fees paid for independent accounting and legal services, costs of
printing  Prospectuses  for Fund  shareholders  and registering a Fund's shares,
postage, insurance premiums, and costs of attending investment conferences.  The
Management  Agreement further provides that IAI will either reimburse a Fund for
the fees and expenses it pays to directors who are not "interested persons" of a
Fund or reduce its fee by an equivalent  amount.  IAI is not liable for any loss
suffered  by a Fund  in  the  absence  of  willful  misfeasance,  bad  faith  or
negligence in the performance of its duties and obligations.

PRIOR AGREEMENTS

     Effective   March  31,  1996,   the  Investment   Advisory   Agreement  and
Administrative  Agreement between each Fund and IAI were terminated and replaced
by the Management  Agreement described above. The services provided by IAI under
each of these agreements are  substantially  similar in nature as those provided
under the new Management Agreement.

     Under the  Investment  Advisory  Agreement,  Developing  Countries Fund had
agreed  to pay IAI an  advisory  fee at an  annual  rate of 1.25% of the  Fund's
average daily net assets of the first $100,000,000 in assets, 1.10% for the next
$100,000,00 in assets and 1.00% for assets above $400,000,000. Through March 31,
1996,  IAI  voluntarily  agreed to waive  certain fees so that total  Developing
Countries  Fund  expenses do not exceed 2.00% of average  daily net assets on an
annual  basis.  International  Fund had agreed to pay IAI a monthly fee of 1.00%
per year of  International  Fund's  average  month-end  net assets for the first
$100,000,000 in assets, 0.85% for the next $100,000,000 in assets, 0.75% for the
next $100,000,000 in assets, and 0.70% for assets above $300,000,000.

         The following table contains relevant information  concerning fees each
Fund paid under the Advisory Agreement:

     With respect to the Administrative Agreement, Developing Countries Fund was
obligated  to pay IAI a monthly  fee at the  annual  rate of .30% of the  Fund's
average daily net assets. For the period from January 31, 1996 through March 31,
1996,  Developing  Countries  Fund  paid  IAI  administrative  fees  of  $3,925.
International  Fund was  obligated to pay IAI a monthly fee equal to .30% of the
Fund's  average  month-end  net  assets.  For the period  from  January 31, 1996
through  March 31,  1996,  International  Fund paid IAI  administrative  fees of
$73,747.

     Effective  March 31, 1996,  each Fund's Plan of  Distribution  (the "Plan")
terminated. Prior to termination,  each Fund had entered into a Distribution and
Shareholder  Services  Agreement (the  "Agreement")  with IAI  Securities,  Inc.
("IAIS").  Pursuant to such Plan and Agreement,  each Fund paid IAIS .25% of the
Fund's average  month-end net assets (daily net assets for Developing  Countries
Fund) to cover  expenses  incurred by IAIS in  connection  with the servicing of
shareholder accounts and the distribution of such Fund's shares,  subject to the
contractual expense limitations discussed above. For the period from January 31,
1996 through March 31, 1996, Developing Countries Fund paid IAIS $3,272. For the
period from January 31, 1996 through  March 31,  1996,  International  Fund paid
IAIS $61,456.  Such  distribution fees (along with amounts paid out of IAIS' own
assets) were utilized in connection  with the  distribution of the Funds' shares
as follows:

ALLOCATION OF EXPENSES

     Prior to the termination of the Advisory and  Administrative  Agreements on
March 31,  1996 as  discussed  above,  each  Fund  paid all its other  costs and
expenses,  including,  for example,  costs  incurred in the purchase and sale of
assets,  interest,  taxes, charges of the custodian of a Fund's assets, costs of
reports and proxy material sent to Fund shareholders,  fees paid for independent
accounting  and  legal  services,   costs  of  printing  Prospectuses  for  Fund
shareholders and registering the Fund's shares,  postage,  fees to directors who
are not "interested persons" of a Fund,  distribution  expenses pursuant to each
Fund's  Rule 12b-1  plan,  insurance  premiums,  costs of  attending  investment
conferences and such other costs which may be designated as extraordinary.  With
respect to  International  Fund,  IAI agreed to reimburse  the Fund for expenses
(other than brokerage  commissions and other expenditures in connection with the
purchase and sale of portfolio securities,  interest expense, and subject to the
specific approval of a majority of the disinterested  directors of International
Fund, taxes and extraordinary expenses which exceed on an annual basis, 2.00% of
the International Fund's average month-end net assets (the "expense limit"). IAI
is not  liable  for any  loss  suffered  by a Fund  in the  absence  of  willful
misfeasance,  bad faith or gross negligence in the performance of its duties and
obligations.

DURATION OF AGREEMENTS

     Each Management Agreement will terminate  automatically in the event of its
assignment.  In  addition,  each  Agreement  is  terminable  at any time without
penalty by the Board of Directors of a Fund or by vote of a majority of a Fund's
outstanding  voting securities on not more than 60 days' written notice,  and by
IAI  (or  IAI  International)  on 60  days'  notice  to the  counterparty.  Each
Management  Agreement shall continue in effect from year to year only so long as
such continuance is specifically  approved at least annually by either the Board
of  Directors  of the Fund or by vote of a majority  of the  outstanding  voting
securities,  provided that in either event such  continuance is also approved by
the vote of a  majority  of  directors  who are not  parties  to the  Management
Agreement  or  interested  persons of such  parties  cast in person at a meeting
called for the purpose of voting on such approval.

     The custodian for the Funds is Norwest Bank Minnesota, N.A. Norwest Center,
Sixth  and  Marquette,  Minneapolis,  MN  55479.  Norwest  has  entered  into an

York  ("Morgan   Stanley")   which  enables   Developing   Countries   Fund  and
International  Fund to utilize the subcustodian and depository network of Morgan
Stanley.  Such agreements,  subcustodians  and depositories were approved by the
Funds' Board of Directors in accordance  with the rules and  regulations  of the
Securities  and  Exchange  Commission,  for the purpose of  providing  custodial
services for the Funds' assets held outside the United States.

               PORTFOLIO TRANSACTIONS AND ALLOCATION OF BROKERAGE

     Most of the Fund's portfolio transactions are effected with dealers without
the payment of brokerage commissions but at a net price which usually includes a
spread or markup. In effecting such portfolio  transactions on behalf of a Fund,
IAI seeks the most favorable net price consistent with the best execution.

     Generally,  however, a Fund must deal with brokers.  IAI selects and (where
applicable) negotiates commissions with the brokers who execute the transactions
for such Fund. The primary criteria for the selection of a broker is the ability
of the  broker,  in the  opinion  of IAI,  to  secure  prompt  execution  of the
transactions on favorable terms,  including the reasonableness of the commission
and considering the state of the market at the time. In selecting a broker,  IAI
may consider  whether such broker provides  brokerage and research  services (as
defined  in  the  Securities   Exchange  Act  of  1934).  IAI  may  direct  Fund
transactions  to brokers who furnish  research  services to IAI.  Such  research
services  include  advice,  both  directly  and in  writing,  as to the value of
securities,  the advisability of investing in, purchasing or selling securities,
and the  availability  of securities or purchasers or sellers of securities,  as
well as analyses and reports concerning issues, industries, securities, economic
factors and trends,  portfolio  strategy,  and the  performance of accounts.  By
allocating  brokerage  business in order to obtain research  services for IAI, a
Fund enables IAI to supplement its own investment research activities and allows
IAI to obtain the views and  information of individuals  and research  staffs of
many different  securities  research firms prior to making investment  decisions
for a Fund. To the extent such  commissions  are directed to brokers who furnish
research  services to IAI, IAI receives a benefit,  not capable of evaluation in
dollar amounts,  without  providing any direct monetary benefit to the Fund from
these commissions. Generally a Fund pays higher than the lowest commission rates
available.

     IAI believes that most research  services  obtained by it generally benefit
one or more of the  investment  companies  or other  accounts  which it manages.
Normally research services obtained through commissions paid by the managed fund
investing in common stocks and managed accounts investing in common stocks would
primarily benefit the fund and accounts.

     There is no formula  for the  allocation  by IAI of each  Fund's  brokerage
business to any broker-dealers for brokerage and research services. However, IAI
will  authorize a Fund to pay an amount of commission for effecting a securities
transaction  in excess of the amount of  commission  another  broker  would have
charged only if IAI  determines  in good faith that such amount of commission is
reasonable  in  relation to the value of the  brokerage  and  research  services
provided by such broker viewed in terms of either that particular transaction or
IAI's  overall  responsibilities  with  respect to the  accounts  as to which it
exercises investment discretion.

     Although investment  decisions for a Fund are made independently from other
accounts as to which IAI gives investment  advice,  it may occasionally  develop
that the same  security is suitable for more than one account.  If and when more
than  one  account  simultaneously  purchase  or sell  the  same  security,  the
transactions  will be  averaged  as to  price  and  allocated  as to  amount  in
accordance  with  arrangements  equitable  to each Fund and such  accounts.  The
simultaneous  purchase  or sale  of the  same  securities  by a Fund  and  other
accounts may have detrimental  effects on the Fund, as they may affect the price
paid or received by a Fund or the size of the position obtainable by a Fund.
                                     
     Consistent  with the Rules of Fair Practice of the National  Association of
Securities Dealers,  Inc. and subject to the policies set forth in the preceding
paragraphs  and such other  policies as the Board of  Directors  of the Fund may
determine,  IAI may  consider  sales  of  shares  of a Fund as a  factor  in the
selection of broker-dealers to execute the Fund's securities transactions.

series have equal rights in the event of liquidation  of that series.  The Board
of Directors of IAI Investment  Funds III, Inc., is empowered under the Articles
of  Incorporation  of such company to issue other series of the company's common
stock  without  shareholder  approval.  IAI  Investment  Funds  III,  Inc.,  has
authorized  10,000,000,000 shares of $.01 par value common stock to be issued as
Series A common shares, and 10,000,000,000 shares of $.01 par value common stock
to be issued as Series B common  shares.  As of  January  31,  1997,  Developing
Countries  Fund had 1,154,272  shares  outstanding  and  International  Fund has
9,598,043 shares outstanding.

                    NET ASSET VALUE AND PUBLIC OFFERING PRICE

     The portfolio securities in which each Fund invests fluctuate in value, and
hence, for each Fund, the net asset value per share also fluctuates.

     The net asset value per share of a Fund is determined  once daily as of the
close of trading on the New York Stock  Exchange on each  business  day on which
the New York  Stock  Exchange  is open for  trading,  and may be  determined  on
additional  days  as  required  by the  Rules  of the  Securities  and  Exchange
Commission.  The New York Stock Exchange is closed,  and the net asset value per
share of a Fund is not  determined,  on the  following  national  holidays:  New
Year's Day, Presidents' Day, Good Friday,  Memorial Day, Independence Day, Labor
Day, Thanksgiving Day, and Christmas Day.

     On January  31,  1997,  the net asset value and public  offering  price per
share of Developing Countries Fund was calculated as follows:

NAV =      Net Assets ($11,981,607)         =    $10.38
           -----------------------------
           Shares Outstanding (1,154,272)

         On January 31, 1997, the net asset value and public  offering price per
share of International Fund was calculated as follows:

NAV =      Net Assets ($116,191,236)        =    $12.11
          -----------------------------
          Shares Outstanding (9,598,043)

                                   TAX STATUS

     The  tax  status  of the  Funds  and the  distributions  of the  Funds  are
summarized in the Prospectus under "Dividends, Distributions and Tax Status."


                                      -24-
<PAGE>

     Because it is expected that no portion of the net investment  income of the
Funds will derive from dividends from domestic corporations, it is probable that
no portion of the dividends paid by the Funds will qualify for the 70% deduction
for dividends received under the provisions of Internal Revenue Code of 1986, as
amended (the "Code").

     If Fund  shares are sold or  otherwise  disposed of more than one year from
the date of  acquisition,  the difference  between the price paid for the shares
and the sales price will result in  long-term  capital  gain or loss to the Fund
shareholder  if, as is usually the case,  the Fund shares are a capital asset in
the  hands  of the Fund  shareholder  at that  time.  However,  under a  special
provision in the Code, if Fund shares with respect to which a long-term  capital
gain  distribution  has been,  or will be, made are held for six months or less,
any loss on the sale or  other  disposition  of such  shares  will be  long-term
capital loss to the extent of such gain distribution.

     Ordinarily,   distributions   and  redemption   proceeds   earned  by  Fund
shareholders are not subject to withholding of federal income tax. However, each
Fund is required to withhold 31% of a shareholder's distributions and redemption
proceeds upon the occurrence of certain events  specified in Section 3406 of the
Code and regulations promulgated thereunder. These events include the failure of
a  Fund  shareholder  to  supply  the  Fund  with  such  shareholder's  taxpayer
identification  number,  and the failure of a Fund  shareholder who is otherwise
exempt from  withholding to properly  document such  shareholder's  status as an
exempt recipient. Additionally,  distributions may be subject to state and local
income taxes,  and the treatment  thereunder  may differ from the federal income
tax consequences discussed above.

     Under the Code,  each Fund will be subject to a  non-deductible  excise tax
equal to 4% of the  excess,  if any,  of the  amount of  investment  income  and
capital gains required to be distributed  pursuant to the Code for each calendar
year over the amount  actually  distributed.  In order to avoid this excise tax,
each Fund  generally  must declare  dividends by the end of each  calendar  year
representing  98% of each Fund's  ordinary income for such calendar year and 98%
of its  capital  gain  net  income  (both  long-term  and  short-term)  for  the
twelve-month  period ending October 31 of the same calendar year. The excise tax
is not imposed,  however,  on  undistributed  income that is already  subject to
corporate  income tax. It is each Fund's policy not to distribute  capital gains
until capital loss carryovers, if any, either are utilized or expire.

     The  amount  of any gain or loss  realized  by each Fund on  closing  out a
futures  contract  may result in a capital  gain or loss for federal  income tax
purposes.  Generally,  futures  contracts  held by each Fund at the close of the
Fund's  taxable year will be treated for federal income tax purposes as sold for
their fair market value on the last business day of such year.  Forty percent of
any gain or loss  resulting  from  such  constructive  sale will be  treated  as
short-term capital gain or loss, and 60% of such gain or loss will be treated as
long-term  capital gain or loss. The amount of any capital gain or loss actually
realized by a Fund in a subsequent  sale or other  disposition  of these futures
contracts  will be  adjusted  to  reflect  any  capital  gain or loss taken into
account  by a Fund in a prior year as a result of the  constructive  sale of the
contract.  Notwithstanding  the rules described  above,  with respect to certain
futures  contracts,  a Fund may make an  election  which will have the effect of
exempting all or a part of those identified futures contracts from being treated
for federal  income tax  purposes as sold on the last  business  day of a Fund's
taxable  year.  All or part of any loss  realized  by a Fund on any closing of a
futures contract may be deferred until all of a Fund's offsetting positions with
respect to the futures contract are closed.

     Generally,  in order to qualify as a  regulated  investment  company  under
Subchapter M of the Code, each Fund must derive at least 90% of its gross income
from dividends,  interest, and gains from the sale or other disposition of stock
or  securities.  Under the Code,  each Fund may  include  income  from  options,
futures and forward  contracts and other gains derived from the Fund's  business
of investing in stock, securities or currencies in determining qualifying income
for purposes of the 90% test. Treasury  regulations may exclude foreign currency
gains not directly related to a Fund's principal business of investing in stocks
or securities (or options and futures with respect to stock or  securities).  It
is  impossible  to predict what amount of such gains,  if any,  future  Treasury
regulations will exclude from qualifying income.

                                      -25-
<PAGE>

     Subchapter  M of the Code also  requires  that less than 30% of each Fund's
gross  income for any year be derived  from gains  realized on the sale or other
disposition of securities,  options, futures contracts or forward contracts held
by a Fund for less than three months.  This rule,  under certain  circumstances,
could require the Fund to defer the closing out of futures contracts until after
three months from the date a Fund  acquired the  contracts,  even if it would be
more  advantageous  to close out the contracts  prior to that time.  However,  a
special rule is provided with respect to certain designated hedging transactions
which  has  the  effect  of  allowing  a  Fund  to  engage  in  such  short-term
transactions in limited circumstances.  Any gains realized by a Fund as a result
of the constructive  sales of futures contracts held by a Fund at the end of its
taxable  year will be treated as derived  from the sale of  securities  held for
three months or more,  regardless of the actual period for which a Fund has held
the futures contracts at the end of the year.

     Under the Code,  dividends of net investment income received from a Fund by
a shareholder who, as to the United States,  is a nonresident  alien individual,
nonresident  fiduciary  of a foreign  trust or estate,  foreign  corporation  or
foreign partnership ("foreign  shareholder") are subject to a withholding tax of
30% (or such lower rate as is prescribed by the income tax  convention,  if any,
in force between the U.S. and the foreign shareholder's  country) without regard
to the amount of gross income that a Fund derives from sources within the United
States.  Distributions of net long-term  capital gains to a foreign  shareholder
will not be subject to U.S. tax unless the foreign  shareholder  is engaged in a
U.S. trade or business to which the distributions  are  attributable,  the gains
are  attributable to the disposition of a United States real property  interest,
or, in the case of a foreign  shareholder who is a nonresident alien individual,
such foreign  shareholder  is  physically  present in the United States for more
than 182 days during the taxable year.

     A  disposition  of shares in a Fund by a foreign  shareholder  resulting in
alternative  minimum  taxable  income or net United States real property gain to
the foreign shareholder may be subject to U.S. tax and withholding if the shares
constitute  United  States real  property  interests  under the Code.  It is not
expected that the shares of a Fund will constitute  such  interests,  and a Fund
will furnish  affidavits  to such effect if necessary and  appropriate  to avoid
application of U.S. tax or withholding on a disposition of shares.

     Income  received from sources  within  foreign  countries may be subject to
withholding and other taxes imposed by such countries.  Tax conventions  between
certain  countries and the United States may reduce or eliminate such taxes.  It
is impossible to determine the effective  rate of foreign tax applicable to such
income in advance since the precise  amount of a Fund's assets to be invested in
various  countries is not known. Any amount of taxes paid by the Fund to foreign
countries will reduce the amount of income available to a Fund for distributions
to shareholders.

     If a Fund is  liable  for  foreign  taxes,  such Fund  expects  to meet the
requirements of the Code for passing through to its  shareholders  foreign taxes
paid, but there can be no assurance that a Fund will be able to do so. Under the
Code, if more than 50% of the value of a Fund's total assets at the close of its
taxable year consist of stock or securities of foreign corporations,  a Fund may
file an election with the Internal Revenue Service to pass through to the Fund's
shareholders  the amount of foreign  taxes  paid by the Fund.  Pursuant  to this
election,  shareholders  will be required  to: (i) include in gross income their
pro rata share of the  foreign  taxes paid by a Fund;  (ii) treat their pro rata
share of foreign  taxes as paid by them;  and (iii) either deduct their pro rata
share of foreign taxes in computing their taxable income or use their share as a
foreign tax credit against U.S. income taxes. No deduction for foreign taxes may
be claimed by a shareholder who does not itemize  deductions.  Each  shareholder
will be notified within 60 days after the close of a Fund's taxable year whether
the foreign taxes paid by a Fund will pass through for that year.

     Under the Code,  the amount of foreign  taxes for which a  shareholder  may
claim a foreign tax credit is subject to limitation based on certain  categories
applicable to the income subjected to foreign tax.  Specifically,  the available
foreign tax credit must be determined separately with respect to nine categories
of  income.  Each Fund may have  foreign  source  income  allocable  to the four
following  categories:  (i) passive income;  (ii) high withholding tax interest;
(iii) dividends from a noncontrolled foreign corporation pursuant to Section 902
of the Code;  and (iv)  other  income  not  specifically  categorized.  Of these
categories,  a substantial part of a Fund income is likely to constitute passive
income.  However,  in  the  absence  of  specific  regulatory  guidance  on  the
application of the income  categories,  such Fund cannot assure  shareholders of
the correctness of any allocation made.

                                      -26-

     The foregoing is a general and abbreviated summary of the Code and Treasury
regulations in effect as of the date of the Funds' Prospectus and this Statement
of Additional Information.


                        LIMITATION OF DIRECTOR LIABILITY

     Under Minnesota law, each Fund's Board of Directors owes certain  fiduciary
duties  to the Fund  and to its  shareholders.  Minnesota  law  provides  that a
director "shall  discharge the duties of the position of director in good faith,
in a manner the director  reasonably  believes to be in the best interest of the
corporation,  and with the care an ordinarily  prudent person in a like position
would exercise under similar circumstances." Fiduciary duties of a director of a
Minnesota  corporation include,  therefore,  both a duty of "loyalty" (to act in
good faith and act in a manner  reasonably  believed to be in the best interests
of the  corporation)  and a duty of "care"  (to act with the care an  ordinarily
prudent person in a like position  would exercise under similar  circumstances).
Minnesota  law  authorizes  corporations  to  eliminate  or limit  the  personal
liability  of a director to the  corporation  or its  shareholders  for monetary
damages  for breach of the  fiduciary  duty of "care."  Minnesota  law does not,
however,  permit a corporation to eliminate or limit the liability of a director
(i) for any breach of the director's duty of "loyalty" to the corporation or its
shareholders,  (ii)  for acts or  omissions  not in good  faith or that  involve
intentional  misconduct or a knowing  violation of law, (iii) for  authorizing a
dividend,  stock repurchase or redemption or other  distribution in violation of
Minnesota  law or for violation of certain  provisions  of Minnesota  securities
laws, or (iv) for any  transaction  from which the director  derived an improper
personal  benefit.  The Articles of  Incorporation  of IAI Investment Funds III,
Inc.,  limit the  liability  of  directors  to the fullest  extent  permitted by
Minnesota  statutes,  except to the extent that such liability cannot be limited
as provided in the  Investment  Company  Act of 1940  (which Act  prohibits  any
provisions  which purport to limit the liability of directors  arising from such
directors'  willful  misfeasance,  bad  faith,  gross  negligence,  or  reckless
disregard of the duties involved in the conduct of their role as directors).

     Minnesota  law  does  not  eliminate  the  duty of  "care"  imposed  upon a
director.  It only authorizes a corporation to eliminate  monetary liability for
violations of that duty. Minnesota law, further,  does not permit elimination or
limitation  of liability of "officers"  of the  corporation  for breach of their
duties as officers  (including  the liability of directors who serve as officers
for  breach  of their  duties  as  officers.)  Minnesota  law  does  not  permit
elimination  or  limitation of the  availability  of equitable  relief,  such as
injunctive  or  rescissionary  relief.  Further,  Minnesota  law does not permit
elimination or limitation of a director's  liability under the Securities Act of
1933 or the Securities  Exchange Act of 1934, and it is uncertain whether and to
what extent the elimination of monetary  liability would extend to violations of
duties imposed on directors by the Investment  Company Act of 1940 and the rules
and regulations adopted under such Act.

     The financial statements, included as part of the Funds' 1997 Annual Report
to Shareholders, are incorporated herein by reference. Such Annual Report may be

                     APPENDIX A - RATINGS OF DEBT SECURITIES



RATINGS BY MOODY'S

Corporate Bonds

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

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

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

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

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

     B.  Bonds  rated  B  generally  lack   characteristics   of  the  desirable
investment. Assurances of interest and principal payment or maintenance of other
terms of the contract over any long period of time may be small.

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

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

     C. Bonds  rated C are the  lowest-rated  class of bonds and issued so rated
can be regarded as having  extremely  poor  prospects of ever attaining any real
investment standing.



                                       A-1
<PAGE>

     Conditional  Ratings. The designation "Con." followed by a rating indicates
bonds for which the  security  depends  upon the  completion  of some act or the
fulfillment  of some  condition.  These are bonds  secured  by (a)  earnings  of
projects under  construction,  (b) earnings or projects  unseasoned in operating
experience,  (c)  rentals  which begin when  facilities  are  completed,  or (d)
payments to which some other limiting condition attaches.  Parenthetical  rating
denotes  probable  credit stature upon completion of construction or elimination
of basis of condition.

     Note:  Moody's  applies  numerical  modifiers  1, 2,  and 3 in the Aa and A
classifications  of its corporate bond rating  system.  The modifier 1 indicates
that the security  ranks in the higher end of its generic rating  category;  the
modifier 2 indicates a mid-range ranking;  and the modifier 3 indicates that the
issue ranks in the lower end of its generic  rating  category.  With  respect to
municipal  securities,  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.

Commercial Paper

     Moody's  employs  the  following  three  designations,  all  judged  to  be
investment grade, to indicate the relative repayment capacity of rated issuers:

     Prime  - 1  Superior  ability  for  repayment  of  senior  short-term  debt
obligations

     Prime  -  2  Strong  ability  for  repayment  of  senior   short-term  debt
obligations

     Prime - 3  Acceptable  ability  for  repayment  of senior  short-term  debt
obligations

     If an issuer  represents to Moody's that its Commercial  Paper  obligations
are supported by the credit of another entity or entities, Moody's, in assigning
ratings to such  issuers,  evaluates  the  financial  strength of the  indicated
affiliated   corporations,   commercial  banks,  insurance  companies,   foreign
governments,  or other  entities,  but only as one  factor in the  total  rating
assessment.


RATINGS BY S&P

Corporate Bonds

     AAA. Debt rated AAA has the highest rating assigned by S&P. Capacity to pay
interest and repay principal is extremely strong.

     AA. Debt rated AA has a very  strong  capacity  to pay  interest  and repay
principal and differs from the higher rated issues only in small degree.

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

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

     BB. Debt rated BB 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.

     B. Debt rated B 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-rating.

     CCC. Debt rated CCC 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.

     CC. Debt rated CC is typically  applied to debt subordinated to senior debt
which is assigned an actual or implied CCC debt rating.

     C. The rating C typically applied to debt subordinated to senior debt which
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.

     C1. The rating C1 is  reserved  for income  bonds on which no  interest  is
being paid.

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

     In order to provide more detailed indications of credit quality, S&P's bond
letter ratings  described above (except for the AAA category) may be modified by
the  addition  of a plus or a minus sign to show  relative  standing  within the
rating category.

Commercial Paper

     A. This highest rating category  indicates the greatest capacity for timely
payment. Issues in this category are further defined with the designations 1, 2,
and 3 to indicate the relative degree to safety.

     A-1. This designation  indicates that the degree of safety regarding timely
payment is either  overwhelming  or very  strong.  Those  issues  determined  to
possess overwhelming safety characteristics are designed A-1+.

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

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