                                    INTRODUCTION

          The Funds described in this SAI are all mutual funds, or open-end, 
management investment companies.  Although each Fund is offering only its own 
shares and is not participating in the sale of the shares of the other Funds, 
it is possible that a Fund might become liable for any misstatement, 
inaccuracy or incomplete disclosure in the Prospectus or SAI concerning the 
other Funds.

1.        PORTFOLIO POLICIES OF THE FUNDS

          The Prospectus describes the investment goals (objectives) of each 
of the Funds and the primary policies to be employed to achieve those 
objectives. This section contains supplemental information concerning the 
types of securities and other instruments in which the Funds may invest, the 
investment policies and portfolio strategies that the Funds may utilize and 
certain risks attendant to those investments, policies and strategies.  For 
the Berger/BIAM International Fund, the term "Fund" in this Section 1 should 
be read to mean the Berger/BIAM International Portfolio (the "Portfolio"), in 
which all the investable assets of the Fund are invested.

          COMMON AND PREFERRED STOCKS.  Stocks represent shares of ownership 
in a company.  Generally, preferred stock has a specified dividend and ranks 
after bonds and before common stocks in its claim on income for dividend 
payments and on assets should the company be liquidated.  After other claims 
are satisfied, common stockholders participate in company profits on a 
pro-rata basis.  Profits may be paid out in dividends or reinvested in the 
company to help it grow. Increases and decreases in earnings are usually 
reflected in a company's stock price, so common stocks generally have the 
greatest appreciation and depreciation potential of all corporate securities. 
 While most preferred stocks pay dividends, any of the Funds may purchase 
preferred stock where the issuer has omitted, or is in danger of omitting, 
payment of its dividends.  Such investments would be made primarily for their 
capital appreciation potential. All investments in stocks are subject to 
market risk, meaning that their prices may move up and down with the general 
stock market, and that such movements might reduce their value.

          DEBT SECURITIES.  Debt securities (such as bonds or debentures) are 
fixed-income  securities which bear interest and are issued by corporations 
or governments.  The issuer has a contractual obligation to pay interest at a 
stated rate on specific dates and to repay principal on a specific maturity 
date.  In addition to market risk, debt securities are generally subject to 
two other kinds of risk:  credit risk and interest rate risk.  Credit risk 
refers to the ability of the issuer to meet interest or principal payments as 
they come due.  The lower the rating given a security by a rating service 
(such as Moody's Investor Service ("Moody's") and Standard & Poor's ("S&P")), 
the greater the credit risk the rating service perceives with respect to that 
security.  None of the  Funds will purchase any nonconvertible securities 
rated below investment grade (Ba or lower by Moody's, BB or lower by S&P).  
In cases where the ratings assigned by more than one rating agency differ, 
the Funds will consider the security as rated in the higher category.  If 
nonconvertible securities purchased by a Fund are downgraded to below 
investment grade following purchase, the directors or trustees of the Fund, 
in consultation with the Fund's advisor or sub-advisor, will determine what 
action, if any, is appropriate in light of all relevant circumstances.   For 
a further discussion of debt security ratings, see Appendix A to this SAI.

          Interest rate risk refers to the fact that the value of 
fixed-income securities (like debt securities) generally fluctuates in 
response to changes in interest rates.  A decrease in interest rates will 
generally result in an increase in the price of fixed-income securities held 
by a Fund.  Conversely, during periods of rising interest rates, the value of 
fixed-income securities held by a Fund will generally decline.  Longer-term 
securities are generally more sensitive to interest rate changes and are more 


                                    -1-

<PAGE>

volatile than shorter-term securities, but they generally offer higher yields 
to compensate investors for the associated risks.

          CONVERTIBLE SECURITIES.  The Funds may also purchase debt or equity 
securities which are convertible into common stock when the Fund's advisor or 
sub-advisor believes they offer the potential for a higher total return than 
nonconvertible securities.  While fixed-income securities generally have a 
priority claim on a corporation's assets over that of common stock, some of 
the convertible securities which the Funds may hold are high-yield/high-risk 
securities that are subject to special risks, including the risk of default 
in interest or principal payments which could result in a loss of income to 
the Fund or a decline in the market value of the securities.  Convertible 
securities often display a degree of market price volatility that is 
comparable to common stocks.  The credit risk associated with convertible 
securities generally is reflected by their ratings by organizations such as 
Moody's or S&P or a similar determination of creditworthiness by the Fund's 
advisor or sub-advisor.  The Funds have no pre-established minimum quality 
standards for convertible securities and may invest in convertible securities 
of any quality, including lower rated or unrated securities.  However, the 
Funds will not invest in any security in default at the time of purchase, and 
each of the Funds will invest less than 20% of the market value of its assets 
at the time of purchase in convertible securities rated below investment 
grade.  If convertible securities purchased by a Fund are downgraded 
following purchase, or if other circumstances cause 20% or more of a Fund's 
assets to be invested in convertible securities rated below investment grade, 
the directors or trustees of the Fund, in consultation with the Fund's 
advisor or sub-advisor, will determine what action, if any, is appropriate in 
light of all relevant circumstances.  For a further discussion of debt 
security ratings, see Appendix A to this SAI.  Convertible securities will be 
included in the 25% of total assets the Berger Balanced Fund will keep in 
fixed-income senior securities.  However, only that portion of their value 
attributable to their fixed-income characteristics will be used in 
calculating the 25%.

          ZEROS/STRIPS.  Certain Funds may invest in zero coupon bonds or in 
"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 coupon 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.  None of the Funds 
will invest in mortgage-backed or other asset-backed securities.

          SECURITIES OF SMALLER COMPANIES.  Each of the Funds may invest in 
securities of companies with small or mid-sized market capitalizations.  
Market capitalization is defined as total current market value of a company's 
outstanding common stock.  Investments in companies with smaller market 
capitalizations may involve greater risks and price volatility (that is, more 
abrupt or erratic price movements) than investments in larger, more mature 
companies since smaller companies may be at an earlier stage of development 
and may have limited product lines, reduced market liquidity for their 
shares, limited financial resources or less depth in management than larger 
or more established companies.  Smaller companies also may be less 
significant factors within their industries and may have difficulty 
withstanding competition from larger companies.  While smaller companies may 
be subject to these additional risks, they may also realize more substantial 
growth than larger or more established companies.

          SECURITIES OF COMPANIES WITH LIMITED OPERATING HISTORIES.  Each of 
the Funds may invest in securities of companies with limited operating 
histories. The Funds consider these to be securities of companies with a 
record of less than three years' continuous operation, even including the 
operations of any predecessors and parents.  (These are sometimes referred to 
as "unseasoned issuers.")  These companies by their nature have only a 
limited operating history which can be used for evaluating the company's 
growth prospects.  As a result, investment decisions for these securities 


                                    -2-

<PAGE>

may place a greater emphasis on current or planned product lines and the 
reputation and experience of the company's management and less emphasis on 
fundamental valuation factors than would be the case for more mature 
companies.  In addition, many of these companies may also be small companies 
and involve the risks and price volatility associated with smaller companies. 

          FOREIGN SECURITIES.  Each Fund may invest in foreign securities, 
which may be traded in foreign markets and denominated in foreign currency.  
The Funds' investments may also include American Depositary Receipts (ADRs), 
European Depositary Receipts (EDRs) which are similar to ADRs, in bearer 
form, designed for use in the European securities markets, and in Global 
Depositary Receipts (GDRs).  

          Investments in foreign securities involve some risks that are 
different from the risks of investing in securities of U.S. issuers, such as 
the risk of adverse political, social, diplomatic and economic developments 
and, with respect to certain countries, the possibility of expropriation, 
taxes imposed by foreign countries or limitations on the removal of monies or 
other assets of the Funds.  Moreover, the economies of individual foreign 
countries will vary in comparison to the U.S. economy in such respects as 
growth of gross domestic product, rate of inflation, capital reinvestment, 
resources, self-sufficiency and balance of payments position.  Securities of 
some foreign companies, particularly those in developing countries, are less 
liquid and more volatile than securities of comparable domestic companies.  A 
developing country generally is considered to be in the initial stages of its 
industrialization cycle.  Investing in the securities of developing countries 
may involve exposure to economic structures that are less diverse and mature, 
and to political systems that can be expected to have less stability than 
developed countries. 
                                           
          There also may be less publicly available information about foreign 
issuers and securities than domestic issuers and securities, and foreign 
issuers generally are not subject to accounting, auditing and financial 
reporting standards, requirements and practices comparable to those 
applicable to domestic issuers.  Also, there is generally less government 
supervision and regulation of exchanges, brokers, financial institutions and 
issuers in foreign countries than there is in the U.S.  Foreign financial 
markets typically have substantially less volume than U.S. markets.  Foreign 
markets also have different clearance and settlement procedures and, in 
certain markets, delays or other factors could make it difficult to effect 
transactions, potentially causing a Fund to experience losses or miss 
investment opportunities.

          Costs associated with transactions in foreign securities are 
generally higher than with transactions in U.S. securities.  A Fund will 
incur greater costs in maintaining assets in foreign jurisdictions and in 
buying and selling foreign securities generally, resulting in part from 
converting foreign currencies into U.S. dollars.  In addition, a Fund might 
have greater difficulty taking appropriate legal action with respect to 
foreign investments in non-U.S. courts than with respect to domestic issuers 
in U.S. courts, which may heighten the risk of possible losses through the 
holding of securities by custodians and securities depositories in foreign 
countries.

          For any Fund invested in securities denominated or quoted in 
currencies other than the U.S. dollar, changes in foreign currency exchange 
rates will affect the value of the investments in its portfolio and the 
unrealized appreciation or depreciation of investments insofar as U.S. 
investors are concerned.  If the foreign currency in which a security is 
denominated appreciates against the U.S. dollar, the dollar value of the 
security will increase.  Conversely, a decline in the exchange rate of the 
foreign currency against the U.S. dollar would adversely affect the dollar 
value of the foreign securities.  Foreign currency exchange rates are 
determined by forces of supply and demand on the foreign exchange markets, 
which are in turn affected by the international balance of payments and other 
economic and financial conditions, government intervention, speculation and 
other factors.

          PASSIVE FOREIGN INVESTMENT COMPANIES (PFICs).  The Funds may 
purchase the securities of certain foreign investment funds or trusts 
considered Passive Foreign Investment Companies (PFICs) under U.S. tax laws.  
In addition to bearing their proportionate share of a Fund's expenses 
(management fees and operating expenses), shareholders will also indirectly 
bear similar expenses of such PFIC.  PFIC investments also may be subject to 
less favorable U.S. tax treatment, as discussed in Section 9 below.

          ILLIQUID AND RESTRICTED SECURITIES.  Each of the Funds (except the 
Berger Small Cap Value Fund) is authorized to invest in securities which are 
illiquid or not readily marketable because they are subject to restrictions 
on their resale ("restricted securities") or because, based upon their nature 
or the market for such securities, no ready market is available.  The Berger 
Small Cap Value Fund is authorized to invest in illiquid securities, but not 
in restricted securities.  However, none of the Funds will purchase any such 
security, the purchase of which would cause the Fund to invest more than 15% 
of its net assets, measured at the time of purchase, in illiquid securities. 
Investments in illiquid securities involve certain risks to the extent that a 
Fund may be unable to dispose of such a security at the time desired or at a 
reasonable price or, in some cases, may be unable to dispose of it at all.  
In addition, in order to resell a restricted security, a Fund might have to 
incur the potentially substantial expense and delay associated with effecting 
registration.  If securities become illiquid following purchase or other 
circumstances cause more than 15% of a Fund's net assets to be invested in 
illiquid securities, the directors or trustees of that Fund, in consultation 
with the Fund's advisor, will determine what action, if any, is appropriate 
in light of all relevant circumstances.

          Repurchase agreements maturing in more than seven days will be 
considered as illiquid for purposes of this restriction.  Pursuant to 
guidelines established by the directors or trustees, a Fund's advisor or 
sub-advisor will determine whether securities eligible for resale to 
qualified institutional buyers pursuant to SEC Rule 144A under the Securities 
Act of 1933 should be treated as illiquid investments considering, among 
other things, the following factors:  (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 other potential purchasers; (3) dealer 
undertakings to make a market in the security; and (4) the nature of the 
security and the marketplace trades (e.g., the time needed to dispose of the 
security, the method of soliciting offers, and the mechanics of the 
transfer).  The liquidity of a Fund's investments in Rule 144A securities 
could be impaired if qualified institutional buyers become uninterested in 
purchasing these securities.

          REPURCHASE AGREEMENTS.  Each Fund may invest in repurchase 
agreements with various financial organizations, including commercial banks, 
registered broker-dealers and registered government securities dealers.  A 
repurchase agreement is an agreement under which a Fund acquires a debt 
security (generally a debt security issued or guaranteed by the U.S. 
government or an agency thereof, a banker's acceptance or a certificate of 
deposit) from a commercial bank, broker or dealer, subject to resale to the 
seller at an agreed upon price and date (normally, the next business day).  A 
repurchase agreement may be considered a loan collateralized by securities.  
The resale price reflects an agreed upon interest rate effective for the 
period the instrument is held by a Fund and is unrelated to the interest rate 
on the underlying instrument.  In these transactions, the securities acquired 
by a Fund (including accrued interest earned thereon) must have a total value 
equal to or in excess of the value of the repurchase agreement and are held 
by the Fund's custodian bank until repurchased.  In addition, the directors 
or trustees will establish guidelines and standards for review by the 
investment advisor of the creditworthiness of any bank, broker or dealer 
party to a repurchase agreement with a Fund.  None of the Funds will enter 
into a repurchase agreement maturing in more than seven days if as a result 
more than 15% of the Fund's total assets would be invested in such repurchase 
agreements and other illiquid securities.

          These transactions must be fully collateralized at all times by 
debt securities (generally a security issued or guaranteed by the U.S. 
Government or an agency thereof, a banker's acceptance 


                                    -4-

<PAGE>

or a certificate of deposit), but involve certain risks, such as credit risk 
to the Fund if the other party defaults on its obligation and the Fund is 
delayed or prevented from liquidating the collateral.   For example, if the 
other party to the agreement defaults on its obligation to repurchase the 
underlying security at a time when the value of the security has declined, a 
Fund may incur a loss upon disposition of the security.  If the other party 
to the agreement becomes insolvent and subject to liquidation or 
reorganization under the Bankruptcy Code or other laws, a court may determine 
that the underlying security is collateral for a loan by a Fund not within 
the control of the Fund and therefore the realization by the Fund on such 
collateral may automatically be stayed and delayed.  Further, it is possible 
that a Fund may not be able to substantiate its interest in the underlying 
security and may be deemed an unsecured creditor of the other party to the 
agreement.  The Funds expect that these risks can be controlled through 
careful monitoring procedures.

          WHEN-ISSUED AND DELAYED DELIVERY SECURITIES.  Each Fund may 
purchase and sell securities on a when-issued or delayed delivery basis.  
However, none of the Funds currently intends to purchase or sell securities 
on a when-issued or delayed delivery basis, if as a result more than 5% of 
its total assets taken at market value at the time of purchase would be 
invested in such securities. When-issued or delayed delivery transactions 
arise when securities (normally, obligations of issuers eligible for 
investment by a Fund) are purchased or sold by the Fund with payment and 
delivery taking place in the future in order to secure what is considered to 
be an advantageous price or yield.  However, the yield available on a 
comparable security when delivery takes place may vary from the yield on the 
security at the time that the when-issued or delayed delivery transaction was 
entered into.  Any failure to consummate a when-issued or delayed delivery 
transaction may result in a Fund missing the opportunity of obtaining a price 
or yield considered to be advantageous.  When-issued and delayed delivery 
transactions may generally be expected to settle within one month from the 
date the transactions are entered into, but in no event later than 90 days.  
However, no payment or delivery is made by a Fund until it receives delivery 
or payment from the other party to the transaction.  

          When a Fund purchases securities on a when-issued basis, it will 
maintain in a segregated account with its custodian cash, U.S. government 
securities or other liquid assets having an aggregate value equal to the 
amount of such purchase commitments, until payment is made.  If necessary, 
additional assets will be placed in the account daily so that the value of 
the account will equal or exceed the amount of the Fund's purchase 
commitments.

          LENDING OF PORTFOLIO SECURITIES.  Certain Funds may lend their 
securities to qualified institutional investors (such as brokers, dealers or 
other financial organizations) who need to borrow securities in order to 
complete certain transactions, such as covering short sales, avoiding 
failures to deliver securities or completing arbitrage operations.  Loans of 
securities by a Fund will be collateralized by cash, letters of credit, or 
securities issued or guaranteed by the U.S. Government or its agencies.  The 
collateral will equal at least 100% of the current market value of the loaned 
securities, marked-to-market on a daily basis.  By lending its securities, 
each of those Funds will be attempting to generate income through the receipt 
of interest on the loan which, in turn, can be invested in additional 
securities to pursue the Fund's investment objective.  Any gain or loss in 
the market price of the securities loaned that might occur during the term of 
the loan would be for the account of the Fund.  

          Each of those Funds may lend its portfolio securities to qualified 
brokers, dealers, banks or other financial institutions, so long as the 
terms, the structure and the aggregate amount of such loans are not 
inconsistent with the Investment Company Act of 1940, or the Rules and 
Regulations or interpretations of the Securities and Exchange Commission (the 
"Commission") thereunder, which currently require that (a) the borrower 
pledge and maintain with the Fund collateral consisting of cash, an 
irrevocable letter of credit or securities issued or guaranteed by the United 
States government having a value at all times not less than 100% of the value 
of the securities loaned, (b) the borrower add to such collateral whenever 
the price of the securities loaned rises (i.e., the borrower "marks to 


                                    -5-

<PAGE>

the market" on a daily basis), (c) the loan be made subject to termination by 
the Fund at any time and (d) the Fund receives reasonable interest on the 
loan, which interest may include the Fund's investing cash collateral in 
interest bearing short-term investments, and (e) the Fund receives all 
dividends and distributions on the loaned securities and any increase in the 
market value of the loaned securities.

          The Funds bear risk of loss in the event that the other party to a 
securities lending transaction defaults on its obligations and the Fund is 
delayed in or prevented from exercising its rights to dispose of the 
collateral, including the risk of a possible decline in the value of the 
collateral securities during the period in which the Fund seeks to assert 
these rights, the risk of incurring expenses associated with asserting these 
rights and the risk of losing all or a part of the income from the 
transaction.  None of the Funds will lend its portfolio securities if, as a 
result, the aggregate value of such loans would exceed 33-1/3% of the value 
of the Fund's total assets.  Loan arrangements made by a Fund will comply 
with all other applicable regulatory requirements, including the rules of the 
New York Stock Exchange, which rules presently require the borrower, after 
notice, to redeliver the securities within the normal settlement time of 
three business days.  All relevant facts and circumstances, including 
creditworthiness of the broker, dealer or institution, will be considered in 
making decisions with respect to the lending of securities, subject to review 
by the Fund's trustees.

          SHORT SALES.  Each Fund currently is only permitted to engage in 
short sales if, at the time of the short sale, the Fund owns or has the right 
to acquire an equivalent kind and amount of the security being sold short at 
no additional cost (i.e., short sales "against the box").

          In a short sale, the seller does not immediately deliver the 
securities sold and is said to have a short position in those securities 
until delivery occurs.  To make delivery to the purchaser, the executing 
broker borrows the securities being sold short on behalf of the seller.  
While the short position is maintained, the seller collateralizes its 
obligation to deliver the securities sold short in an amount equal to the 
proceeds of the short sale plus an additional margin amount established by 
the Board of Governors of the Federal Reserve.  If a Fund engages in a short 
sale, the collateral account will be maintained by the Fund's custodian.  
While the short sale is open, the Fund will maintain in a segregated 
custodial account an amount of securities convertible into or exchangeable 
for such equivalent securities at no additional cost.  These securities would 
constitute the Fund's long position.

          Historically, a Fund could have made a short sale, as described 
above, when it wanted to sell a security it owned at a current attractive 
price, but also wished to defer recognition of gain or loss for Federal 
income tax purposes and for purposes of satisfying certain tests applicable 
to regulated investment companies under the Internal Revenue Code.  However, 
recent federal tax legislation eliminated the ability to defer recognition of 
gain or loss in short sales against the box and accordingly, it is not 
anticipated that any of the Funds will be engaging in these transactions 
unless there are further legislative changes.

          SPECIAL SITUATIONS.  Each Fund may also invest in special 
situations, that is, in common stocks of companies that have recently 
experienced or are anticipated to experience a significant change in 
structure, management, products or services.  Examples of special situations 
are companies being reorganized or merged, companies having unusual new 
products, or which enjoy particular tax advantages, or companies that are run 
by new management or may be probable takeover candidates.  The opportunity to 
invest in special situations, however, is limited and depends in part on the 
market's assessment of these issuers and their circumstances.  In addition, 
stocks of companies in special situations may be more volatile, since the 
market value of these stocks may decline if an anticipated event or benefit 
does not materialize.

          HEDGING TRANSACTIONS.  Each Fund is authorized to make limited use 
of certain types of futures, forwards and/or options, but only for the 
purpose of hedging, that is, protecting against market risk due to market 
movements that may adversely affect the value of a Fund's securities or the 


                                    -6-

<PAGE>

price of securities that a Fund is considering purchasing.  The utilization 
of futures, forwards and options is also subject to policies and procedures 
which may be established by the directors or trustees from time to time.  A 
hedging transaction may partially protect a Fund from a decline in the value 
of a particular security or its portfolio generally, although hedging may 
also limit a Fund's opportunity to profit from favorable price movements, and 
the cost of the transaction will reduce the potential return on the security 
or the portfolio.  Use of these instruments by a Fund involves the potential 
for a loss that may exceed the amount of initial margin the Fund would be 
permitted to commit to the contracts under its investment limitation, or in 
the case of a call option written by the Fund, may exceed the premium 
received for the option.  However, a Fund is permitted to use such 
instruments for hedging purposes only, and only if the aggregate amount of 
its obligations under these contracts does not exceed the total market value 
of the assets the Fund is attempting to hedge, such as a portion or all of 
its exposure to equity securities or its holding in a specific foreign 
currency.  To help ensure that the Fund will be able to meet its obligations 
under its futures and forward contracts and its obligations under options 
written by that Fund, the Fund will be required to maintain liquid assets in 
a segregated account with its custodian bank or to set aside portfolio 
securities to "cover" its position in these contracts.

          The principal risks of a Fund utilizing futures transactions, 
forward contracts and options are:  (a) losses resulting from market 
movements not anticipated by the Fund; (b) possible imperfect correlation 
between movements in the prices of futures, forwards and options and 
movements in the prices of the securities or currencies hedged or used to 
cover such positions; (c) lack of assurance that a liquid secondary market 
will exist for any particular futures or options at any particular time, and 
possible exchange-imposed price fluctuation limits, either of which may make 
it difficult or impossible to close a position when so desired; (d) lack of 
assurance that the counterparty to a forward contract would be willing to 
negotiate an offset or termination of the contract when so desired; and (e) 
the need for additional information and skills beyond those required for the 
management of a portfolio of traditional securities.  In addition, when the 
Fund enters into an over-the-counter contract with a counterparty, the Fund 
will assume counterparty credit risk, that is, the risk that the counterparty 
will fail to perform its obligations, in which case the Fund could be worse 
off than if the contract had not been entered into.  

          Following is additional information concerning the futures, 
forwards and options which the Berger New Generation Fund, the Berger Select 
Fund, the Berger Small Company Growth Fund, the Berger Mid Cap Growth Fund, 
the Berger 100 Fund, the Berger Growth and Income Fund and the Berger 
Balanced Fund may utilize, provided that no more than 5% of the Fund's net 
assets at the time the contract is entered into may be used for initial 
margins for financial futures transactions and premiums paid for the purchase 
of options.  In addition, those Funds may only write call options that are 
covered and only up to 25% of the Fund's total assets.   

          Currently, the Berger/BIAM International Fund is authorized to 
utilize only forward contracts for hedging purposes and is not permitted to 
utilize futures or options.  Consequently, the following additional 
information should be read as applicable to that Fund only to the extent it 
discusses forwards.  If the trustees ever authorize that Fund to utilize 
futures or options, such investments would be permitted solely for hedging 
purposes, and the Fund would not be permitted to invest more than 5% of its 
net assets at the time of purchase in initial margins for financial futures 
transactions and premiums for options.  In addition, the Fund's advisor or 
sub-advisor may be required to obtain bank regulatory approval before that 
Fund engages in futures and options transactions. 

          Currently, the Berger Small Cap Value Fund is authorized to utilize 
only options for hedging purposes and is not permitted to utilize futures or 
forwards.  Consequently, the following additional information should be read 
as applicable to that Fund only to the extent it discusses options.  If the 
trustees ever authorize that Fund to utilize futures or forwards, such 
investments would be permitted solely for hedging purposes, and the Fund 
would not be permitted to invest more than 5% 

                                    -7-

of its net assets at the time of purchase in initial margins for financial 
futures transactions and premiums for options.  

          FUTURES CONTRACTS.       Financial futures contracts are 
exchange-traded contracts on financial instruments (such as securities and 
foreign currencies) and securities indices that obligate the holder to take 
or make delivery of a specified quantity of the underlying financial 
instrument, or the cash value of an index, at a future date.  Although 
futures contracts by their terms call for the delivery or acquisition of the 
underlying instruments or a cash payment based on the mark-to-market value of 
the underlying instruments, in most cases the contractual obligation will be 
offset before the delivery date by buying (in the case of an obligation to 
sell) or selling (in the case of an obligation to buy) an identical futures 
contract.  Such a transaction cancels the original obligation to make or take 
delivery of the instruments.

          Certain Funds may enter into contracts for the purchase or sale for 
future delivery of financial instruments, such as securities and foreign 
currencies, or contracts based on financial indices including indices of U.S. 
Government securities, foreign government securities or equity securities.  
U.S. futures contracts are traded on exchanges which have been designated 
"contract markets" by the Commodity Futures Trading Commission ("CFTC") and 
must be executed through a futures commission merchant (an "FCM"), or 
brokerage firm, which is a member of the relevant contract market.  Through 
their clearing corporations, the exchanges guarantee performance of the 
contracts as between the clearing members of the exchange.

          Both the buyer and seller are required to deposit "initial margin" 
for the benefit of the FCM when a futures contract is entered into.  Initial 
margin deposits are equal to a percentage of the contract's value, as set by 
the exchange on which the contract is traded, and may be maintained in cash 
or other liquid assets.  If the value of either party's position declines, 
that party will be required to make additional "variation margin" payments to 
the other party to settle the change in value on a daily basis.  Initial and 
variation margin payments are similar to good faith deposits or performance 
bonds or party-to-party payments resulting from daily changes in the value of 
the contract, unlike margin extended by a securities broker, and would be 
released or credited to the Funds upon termination of the futures contract, 
assuming all contractual obligations have been satisfied.  Unlike margin 
extended by a securities broker, initial and variation margin payments do not 
constitute purchasing securities on margin for purposes of a Fund's 
investment limitations. A Fund will incur brokerage fees when it buys or 
sells futures contracts.

          In the event of the bankruptcy of the FCM that holds margin on 
behalf of a Fund, the Fund may be entitled to return of margin owed to the 
Fund only in proportion to the amount received by the FCM's other customers.  
A Fund will attempt to minimize the risk by careful monitoring of the 
creditworthiness of the FCMs with which the Fund does business and by 
depositing margin payments in a segregated account with the Fund's custodian 
for the benefit of the FCM when practical or otherwise required by law.

          Where applicable, each Fund intends to comply with guidelines of 
eligibility for exclusion from the definition of the term "commodity pool 
operator" with the CFTC and the National Futures Association, which regulate 
trading in the futures markets.  Accordingly, a Fund will not enter into any 
futures contract or option on a futures contract if, as a result, the 
aggregate initial margin and premiums required to establish such positions 
would exceed 5% of the Fund's net assets.

          Although a Fund would hold cash and liquid assets in a segregated 
account with a mark-to-market value sufficient to cover the Fund's open 
futures obligations, the segregated assets would be available to the Fund 
immediately upon closing out the futures position.


                                    -8-

          The acquisition or sale of a futures contract may occur, for 
example, when a Fund is considering purchasing or holds equity securities and 
seeks to protect itself from fluctuations in prices without buying or selling 
those securities.  For example, if prices were expected to decrease, the Fund 
might sell equity index futures contracts, thereby hoping to offset a 
potential decline in the value of equity securities in the portfolio by a 
corresponding increase in the value of the futures contract position held by 
the Fund and thereby preventing the Fund's net asset value from declining as 
much as it otherwise would have.  A Fund also could protect against potential 
price declines by selling portfolio securities and investing in money market 
instruments.  However, the use of futures contracts as a hedging technique 
allows a Fund to maintain a defensive position without having to sell 
portfolio securities.

          Similarly, when prices of equity securities are expected to 
increase, futures contracts may be bought to attempt to hedge against the 
possibility of having to buy equity securities at higher prices.  This 
technique is sometimes known as an anticipatory hedge.  Since the 
fluctuations in the value of futures contracts should be similar to those of 
equity securities, a Fund could take advantage of the potential rise in the 
value of equity securities without buying them until the market has 
stabilized.  At that time, the futures contracts could be liquidated and the 
Fund could buy equity securities on the cash market.  

          The ordinary spreads between prices in the cash and futures 
markets, due to differences in the nature of those markets, are subject to 
distortions. First, all participants in the futures market are subject to 
initial margin and variation margin requirements.  Rather than meeting 
additional variation margin requirements, investors may close out futures 
contracts through offsetting transactions which could distort the normal 
price relationship between the cash and futures markets.  Second, the 
liquidity of the futures market depends on participants entering into 
offsetting transactions rather than making or taking delivery.  To the extent 
participants decide to make or take delivery, liquidity in the futures market 
could be reduced and prices in the futures market distorted.  Third, from the 
point of view of speculators, the margin deposit requirements in the futures 
market are less than margin requirements in the securities market.  
Therefore, increased participation by speculators in the futures market may 
cause temporary price distortions.  Due to the possibility of the foregoing 
distortions, a correct forecast of general price trends by a Fund still may 
not result in a successful use of futures.

          Futures contracts entail additional risks.  Although a Fund will 
only utilize futures contracts when it believes that use of such contracts 
will benefit the Fund, if the Fund's investment judgment is incorrect, the 
Fund's overall performance could be worse than if the Fund had not entered 
into futures contracts.  For example, if the Fund has hedged against the 
effects of a possible decrease in prices of securities held in the Fund's 
portfolio and prices increase instead, the Fund will lose part or all of the 
benefit of the increased value of these securities because of offsetting 
losses in the Fund's futures positions.  In addition, if the Fund has 
insufficient cash, it may have to sell securities from its portfolio to meet 
daily variation margin requirements.  Those sales may be, but will not 
necessarily be, at increased prices which reflect the rising market and may 
occur at a time when the sales are disadvantageous to the Fund.  Although the 
buyer of an option cannot lose more than the amount of the premium plus 
related transaction costs, a buyer or seller of futures contracts could lose 
amounts substantially in excess of any initial margin deposits made, due to 
the potential for adverse price movements resulting in additional variation 
margin being required by such positions. However, each Fund utilizing futures 
contracts intends to monitor its investments closely and will attempt to 
close its positions when the risk of loss to the Fund becomes unacceptably 
high. 

          The prices of futures contracts depend primarily on the value of 
their underlying instruments.  Because there are a limited number of types of 
futures contracts, it is possible that the standardized futures contracts 
available to a Fund will not match exactly the Fund's current or potential 
investments.  A Fund may buy and sell futures contracts based on underlying 
instruments with 


                                    -9-

<PAGE>

different characteristics from the securities in which it typically invests 
- -- for example, by hedging investments in portfolio securities with a futures 
contract based on a broad index of securities -- which involves a risk that 
the futures position will not correlate precisely with the performance of the 
Fund's investments.

          Futures prices can also diverge from the prices of their underlying 
instruments, even if the underlying instruments closely correlate with a 
Fund's investments.  Futures prices are affected by such factors as current 
and anticipated short-term interest rates, changes in volatility of the 
underlying instruments and the time remaining until expiration of the 
contract.  Those factors may affect securities prices differently from 
futures prices.  Imperfect correlations between a Fund's investments and its 
futures positions may also result from differing levels of demand in the 
futures markets and the securities markets, from structural differences in 
how futures and securities are traded, and from imposition of daily price 
fluctuation limits for futures contracts.  A Fund may buy or sell futures 
contracts with a value less than or equal to the securities it wishes to 
hedge or is considering purchasing.  If price changes in a Fund's futures 
positions are poorly correlated with its other investments, its futures 
positions may fail to produce desired gains or result in losses that are not 
offset by the gains in the Fund's other investments.

          Because futures contracts are generally settled within a day from 
the date they are closed out, compared with a longer settlement period for 
most types of securities, the futures markets can provide superior liquidity 
to the securities markets.  Nevertheless, there is no assurance a liquid 
secondary market will exist for any particular futures contract at any 
particular time. In addition, futures exchanges may establish daily price 
fluctuation limits for 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, it may be 
impossible for a Fund to enter into new positions or close out existing 
positions.  If the secondary market for a futures contract is not liquid 
because of price fluctuation limits or otherwise, a Fund may not be able to 
promptly liquidate unfavorable futures positions and potentially could be 
required to continue to hold a futures position until the delivery date, 
regardless of changes in its value.  As a result, a Fund's access to other 
assets held to cover its futures positions also could be impaired.

          OPTIONS ON FUTURES CONTRACTS.  Certain Funds may buy and write 
options on futures contracts for hedging purposes.  An option on a futures 
contract gives a Fund the right (but not the obligation) to buy or sell a 
futures contract at a specified price on or before a specified date.  The 
purchase of a call option on a futures contract is similar in some respects 
to the purchase of a call option on an individual security.  Depending on the 
pricing of the option compared to either the price of the futures contract 
upon which it is based or the price of the underlying instrument, ownership 
of the option may or may not be less risky than ownership of the futures 
contract or the underlying instrument.  As with the purchase of futures 
contracts, a Fund may buy a call option on a futures contract to hedge 
against a market advance, and a Fund might buy a put option on a futures 
contract to hedge against a market decline.

          The writing of a call option on a futures contract constitutes a 
partial hedge against declining prices of the security or foreign currency 
which is deliverable under, or of the index comprising, the futures contract. 
 If the futures price at the expiration of the call option is below the 
exercise price, a Fund will retain the full amount of the option premium 
which provides a partial hedge against any decline that may have occurred in 
the Fund's portfolio holdings.  If a call option a Fund has written is 
exercised, the Fund will incur a loss which will be reduced by the amount of 
the premium it received. Depending on the degree of correlation between 
change in the value of its portfolio securities and changes in the value of 
the futures positions, a Fund's losses from existing options on futures may 
to some extent be reduced or increased by changes in the value of portfolio 
securities.


                                    -10-

<PAGE>

          The purchase of a put option on a futures contract is similar in 
some respects to the purchase of protective put options on portfolio 
securities.  For example, a Fund may buy a put option on a futures contract 
to hedge the Fund's portfolio against the risk of falling prices.

          The amount of risk a Fund assumes when it buys an option on a 
futures contract is the premium paid for the option plus related transaction 
costs.  In addition to the correlation risks discussed above, the purchase of 
an option also entails the risk that changes in the value of the underlying 
futures contract will not be fully reflected in the value of the options 
bought.

          FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS.  A forward contract is 
a privately negotiated agreement between two parties in which one party is 
obligated to deliver a stated amount of a stated asset at a specified time in 
the future and the other party is obligated to pay a specified invoice amount 
for the assets at the time of delivery.  The Funds authorized to utilize 
forward contracts currently intend that they will only use forward contracts 
or commitments for hedging purposes and will only use forward foreign 
currency exchange contracts, although a Fund may enter into additional forms 
of forward contracts or commitments in the future if they become available 
and advisable in light of the Funds' objectives and investment policies.  
Forward contracts generally are negotiated in an interbank market conducted 
directly between traders (usually large commercial banks) and their 
customers.  Unlike futures contracts, which are standardized exchange-traded 
contracts, forward contracts can be specifically drawn to meet the needs of 
the parties that enter into them. The parties to a forward contract may agree 
to offset or terminate the contract before its maturity, or may hold the 
contract to maturity and complete the contemplated exchange.

          The following discussion summarizes the relevant Funds' principal 
uses of forward foreign currency exchange contracts ("forward currency 
contracts"). A Fund may enter into forward currency contracts with stated 
contract values of up to the value of the Fund's assets.  A forward currency 
contract is an obligation to buy or sell an amount of a specified currency 
for an agreed price (which may be in U.S. dollars or a foreign currency) on a 
specified date.  A Fund will exchange foreign currencies for U.S. dollars and 
for other foreign currencies in the normal course of business and may buy and 
sell currencies through forward currency contracts in order to fix a price 
(in terms of a specified currency) for securities it has agreed to buy or 
sell ("transaction hedge").  A Fund also may hedge some or all of its 
investments denominated in foreign currency against a decline in the value of 
that currency (or a proxy currency whose price movements are expected to have 
a high degree of correlation with the currency being hedged) relative to the 
U.S. dollar by entering into forward currency contracts to sell an amount of 
that currency approximating the value of some or all of its portfolio 
securities denominated in that currency ("position hedge") or by 
participating in futures contracts (or options on such futures) with respect 
to the currency.  A Fund also may enter into a forward currency contract with 
respect to a currency where the Fund is considering the purchase or sale of 
investments denominated in that currency but has not yet selected the 
specific investments ("anticipatory hedge").

          These types of hedging minimize the effect of currency appreciation 
as well as depreciation, but do not eliminate fluctuations in the underlying 
U.S. dollar equivalent value of the proceeds of or rates of return on a 
Fund's foreign currency denominated portfolio securities.  The matching of 
the increase in value of a forward contract and the decline in the U.S. 
dollar equivalent value of the foreign currency denominated asset that is the 
subject of the hedge generally will not be precise.  Shifting a Fund's 
currency exposure from one foreign currency to another limits that Fund's 
opportunity to profit from increases in the value of the original currency 
and involves a risk of increased losses to such Fund if its investment 
manager's projection of future exchange rates is inaccurate.  Unforeseen 
changes in currency prices may result in poorer overall performance for a 
Fund than if it had not entered into such contracts.

          A Fund will cover outstanding forward currency contracts by 
maintaining liquid portfolio securities denominated in the currency 
underlying the forward contract or the currency being hedged.  

                                    -11-

<PAGE>

To the extent that a Fund is not able to cover its forward currency positions 
with underlying portfolio securities, the Funds' custodian will segregate 
cash or liquid assets having a value equal to the aggregate amount of such 
Fund's commitments under forward contracts entered into.  If the value of the 
securities used to cover a position or the value of segregated assets 
declines, the Fund must find alternative cover or segregate additional cash 
or liquid assets on a daily basis so that the value of the covered and 
segregated assets will be equal to the amount of a Fund's commitments with 
respect to such contracts.  

          While forward contracts are not currently regulated by the CFTC, 
the CFTC may in the future assert authority to regulate forward contracts.  
In such event, the Funds' ability to utilize forward contracts may be 
restricted.  A Fund may not always be able to enter into forward contracts at 
attractive prices and may be limited in its ability to use these contracts to 
hedge Fund assets. In addition, when a Fund enters into a privately 
negotiated forward contract with a counterparty, the Fund assumes 
counterparty credit risk, that is, the risk that the counterparty will fail 
to perform its obligations, in which case the Fund could be worse off than if 
the contract had not been entered into. Unlike many exchange-traded futures 
contracts and options on futures, there are no daily price fluctuation limits 
with respect to forward contracts and other negotiated or over-the-counter 
instruments, and with respect to those contracts, adverse market movements 
could therefore continue to an unlimited extent over a period of time.  
However, each Fund utilizing forward contracts intends to monitor its 
investments closely and will attempt to renegotiate or close its positions 
when the risk of loss to the Fund becomes unacceptably high.  

          OPTIONS ON SECURITIES AND SECURITIES INDICES.  Certain Funds may 
buy or sell put or call options and write covered call options on securities 
that are traded on United States or foreign securities exchanges or 
over-the-counter. Buying an option involves the risk that, during the option 
period, the price of the underlying security will not increase (in the case 
of a call) to above the exercise price, or will not decrease (in the case of 
a put) to below the exercise price, in which case the option will expire 
without being exercised and the holder would lose the amount of the premium.  
Writing a call option involves the risk of an increase in the market value of 
the underlying security, in which case the option could be exercised and the 
underlying security would then be sold by a Fund to the option holder at a 
lower price than its current market value and the Fund's potential for 
capital appreciation on the security would be limited to the exercise price.  
Moreover, when a Fund writes a call option on a securities index, the Fund 
bears the risk of loss resulting from imperfect correlation between movements 
in the price of the index and the price of the securities set aside to cover 
such position.  Although they entitle the holder to buy equity securities, 
call options to purchase equity securities do not entitle the holder to 
dividends or voting rights with respect to the underlying securities, nor do 
they represent any rights in the assets of the issuer of those securities.  

          A call option written by a Fund is "covered" if the Fund owns the 
underlying security covered by the call or has an absolute and immediate 
right to acquire that security without additional cash consideration (or for 
additional cash consideration held in a segregated account by its custodian) 
upon conversion or exchange of other securities held in its portfolio.  A 
call option is also deemed to be covered if a Fund holds a call on the same 
security and in the same principal amount as the call written and the 
exercise price of the call held (i) is equal to or less than the exercise 
price of the call written or (ii) is greater than the exercise price of the 
call written if the difference is maintained by the Fund in liquid assets in 
a segregated account with its custodian.

          The writer of a call option may have no control when the underlying 
securities must be sold.  Whether or not an option expires unexercised, the 
writer retains the amount of the premium.  This amount, of course, may, in 
the case of a covered call option, be offset by a decline in the market value 
of the underlying security during the option period.  


                                    -12-

<PAGE>

          The writer of an exchange-traded call option that wishes to 
terminate its obligation may effect a "closing purchase transaction."  This 
is accomplished by buying an option of the same series as the option 
previously written.  The effect of the purchase is that the writer's position 
will be cancelled by the clearing corporation.  If a Fund desires to sell a 
particular security from the Fund's portfolio on which the Fund has written a 
call option, the Fund will effect a closing transaction prior to or 
concurrent with the sale of the security.  However, a writer may not effect a 
closing purchase transaction after being notified of the exercise of an 
option.  An investor who is the holder of an exchange-traded option may 
liquidate its position by effecting a "closing sale transaction."  This is 
accomplished by selling an option of the same series as the option previously 
bought.  There is no guarantee that either a closing purchase or a closing 
sale transaction can be effected.

          A Fund will realize a profit from a closing transaction if the 
price of the purchase transaction is less than the premium received from 
writing the option or the price received from a sale transaction is more than 
the premium paid to buy the option; the Fund will realize a loss from a 
closing transaction if the price of the purchase transaction is more than the 
premium received from writing the option or the price received from a sale 
transaction is less than the premium paid to buy the option.  Because 
increases in the market price of a call option will generally reflect 
increases in the market price of the underlying security, any loss resulting 
from the repurchase of a call option is likely to be offset in whole or in 
part by appreciation of the underlying security owned by the Fund.

          An option position may be closed out only where there exists a 
secondary market for an option of the same series.  If a secondary market 
does not exist, it might not be possible to effect closing transactions in 
particular options with the result that a Fund would have to exercise the 
options in order to realize any profit.  If a Fund is unable to effect a 
closing purchase transaction in a secondary market, it will not be able to 
sell the underlying security until the option expires or the Fund delivers 
the underlying security upon exercise.  Reasons for the absence of a liquid 
secondary market may include the following:  (i) there may be insufficient 
trading interest in certain options, (ii) restrictions may be imposed by a 
national securities exchange on which the option is traded ("Exchange") on 
opening or closing transactions or both, (iii) trading halts, suspensions or 
other restrictions may be imposed with respect to particular classes or 
series of options or underlying securities, (iv) unusual or unforeseen 
circumstances may interrupt normal operations on an Exchange, (v) the 
facilities of an Exchange or of the Options Clearing Corporation ("OCC") may 
not at all times be adequate to handle current trading volume, or (vi) one or 
more Exchanges could, for economic or other reasons, decide or be compelled 
at some future date to discontinue the trading of options (or a particular 
class or series of options), in which event the secondary market on that 
Exchange (or in that class or series of options) would cease to exist, 
although outstanding options on that Exchange that had been issued by the OCC 
as a result of trades on that Exchange would continue to be exercisable in 
accordance with their terms.  

          In addition, when a Fund enters into an over-the-counter option 
contract with a counterparty, the Fund assumes counterparty credit risk, that 
is, the risk that the counterparty will fail to perform its obligations, in 
which case the Fund could be worse off than if the contract had not been 
entered into.  

          An option on a securities index is similar to an option on a 
security except that, rather than the right to take or make delivery of a 
security at a specified price, an option on a securities index gives the 
holder the right to receive, on exercise of the option, an amount of cash if 
the closing level of the securities index on which the option is based is 
greater than, in the case of a call, or less than, in the case of a put, the 
exercise price of the option.

          A Fund may buy call options on securities or securities indices to 
hedge against an increase in the price of a security or securities that the 
Fund may buy in the future.  The premium paid for the call option plus any 
transaction costs will reduce the benefit, if any, realized by a Fund upon 


                                    -13-

<PAGE>

exercise of the option, and, unless the price of the underlying security or 
index rises sufficiently, the option may expire and become worthless to the 
Fund.  A Fund may buy put options to hedge against a decline in the value of 
a security or its portfolio.  The premium paid for the put option plus any 
transaction costs will reduce the benefit, if any, realized by a Fund upon 
exercise of the option, and, unless the price of the underlying security or 
index declines sufficiently, the option may expire and become worthless to 
the Fund.  

          An example of a hedging transaction using an index option would be 
if a Fund were to purchase a put on a stock index, in order to protect the 
Fund against a decline in the value of all securities held by it to the 
extent that the stock index moves in a similar pattern to the prices of the 
securities held. While the correlation between stock indices and price 
movements of the stocks in which the Funds will generally invest may be 
imperfect, the Funds utilizing put options expect, nonetheless, that the use 
of put options that relate to such indices will, in certain circumstances, 
protect against declines in values of specific portfolio securities or the 
Fund's portfolio generally.  Although the purchase of a put option may 
partially protect a Fund from a decline in the value of a particular security 
or its portfolio generally, the cost of a put will reduce the potential 
return on the security or the portfolio.

          TEMPORARY DEFENSIVE MEASURES.  Each of the Funds (except the 
Berger/BIAM International Fund) may increase its investment in government 
securities, and other short-term, interest-bearing securities without regard 
to the Fund's otherwise applicable percentage limits, policies or its normal 
investment emphasis when its advisor or sub-advisor believes market 
conditions warrant a temporary defensive position.  Taking larger positions 
in such short-term investments may serve as a means of preserving capital in 
unfavorable market conditions.  During these periods, a Fund may not 
participate in stock or bond market advances or declines to the same extent 
that it would if the Fund remained more fully invested in stocks and bonds 
and it may be more difficult for the Fund to achieve its investment objective.

          NON-DIVERSIFICATION.  The Berger Select Fund is classified as a 
"non-diversified" Fund under the Investment Company Act of 1940, which means 
that the Fund is not limited by that Act in the proportion of its assets that 
it may invest in the securities of a single issuer.  The Fund's net asset 
value may be more volatile than that of a more-widely diversified fund 
because the Fund invests more of its assets in a smaller number of issuers.  
Consequently, the Fund may be more vulnerable to any single economic, 
political or regulatory occurrence, and the gains or losses on a single stock 
will have a greater impact on the Fund's net asset value. 

          However, the Fund intends to conduct its operations so as to 
qualify to be taxed as a "regulated investment company" under the Internal 
Revenue Code, which will generally relieve the Fund of any liability for 
federal income tax to the extent its earnings are distributed to 
shareholders.  See Section 9--Income Dividends, Capital Gains Distributions 
and Tax Treatment below.  To qualify as a regulated investment company, among 
other requirements, the Fund will limit its investments so that, at the close 
of each quarter of the taxable year, (i) not more than 25% of the market 
value of the Fund's total assets will be invested in securities of a single 
issuer, and (ii) with respect to 50% of the market value of its total assets, 
not more than 5% of the market value of its total assets will be invested in 
the securities of a single issuer and the Fund will not own more than 10% of 
the outstanding voting securities of a single issuer.  These limitations do 
not apply to U.S. government securities.

          PORTFOLIO TURNOVER.  The portfolio turnover rates of each of the 
Funds are shown in the Financial Highlights tables included in the 
Prospectus.  The annual portfolio turnover rates of some of the Funds at 
times have exceeded 100%.  A 100% annual turnover rate results, for example, 
if the equivalent of all of the securities in the Fund's portfolio are 
replaced in a period of one year.  The Funds anticipate that their portfolio 
turnover rates in future years may exceed 100%, and investment changes 

                                    -14-

<PAGE>

will be made whenever management deems them appropriate even if this results 
in a higher portfolio turnover rate.  In addition, portfolio turnover for all 
the Funds may increase as a result of large amounts of purchases and 
redemptions of shares of the Funds due to economic, market or other factors 
that are not within the control of management.  The annual portfolio turnover 
rates for the Berger Balanced Fund and the Berger Mid Cap Growth Fund are not 
expected to exceed 200%.  The annual portfolio turnover rate for the Berger 
Select Fund is not expected to exceed 300%.  

          Higher portfolio turnover will necessarily result in 
correspondingly higher brokerage costs for the Funds.  The existence of a 
high portfolio turnover rate has no direct relationship to the tax liability 
of a Fund, although sales of certain stocks will lead to realization of 
gains, and, possibly, increased taxable distributions to shareholders.  The 
Funds' brokerage policy is discussed further below under Section 6--Brokerage 
Policy, and additional information concerning income taxes is located under 
Section 9--Income Dividends, Capital Gains Distributions and Tax Treatment.

2.        INVESTMENT RESTRICTIONS

          The investment objective of each Fund is set forth on the cover of 
this SAI.  The investment objective of the Berger New Generation Fund, the 
Berger Select Fund, the Berger Small Company Growth Fund, the Berger Small 
Cap Value Fund, the Berger Mid Cap Growth Fund, the Berger 100 Fund, the 
Berger/BIAM International Fund and the Berger Balanced Fund, and the primary 
investment objective of the Berger Growth and Income Fund, are considered 
fundamental, meaning that they cannot be changed without a shareholders' 
vote.  The secondary investment objective of the Berger Growth and Income 
Fund is not considered fundamental, and therefore may be changed in the 
future by action of the directors without shareholder vote.  However, the 
Berger Growth and Income Fund will not change its secondary investment 
objective without giving its shareholders such notice as may be required by 
law.  If the Berger Growth and Income Fund changes its secondary investment 
objective, shareholders should consider whether the Fund remains an 
appropriate investment in light of their then current financial position and 
needs.  There can be no assurance that any of the Funds' investment 
objectives will be realized. 

          Each Fund has adopted certain fundamental and non-fundamental 
restrictions on its investments and other activities.  Fundamental 
restrictions may not be changed without the approval of (i) 67% or more of 
the voting securities of the Fund present at a meeting of shareholders 
thereof if the holders of more than 50% of the outstanding voting securities 
are present or represented by proxy, or (ii) more than 50% of the outstanding 
voting securities of the Fund.  Non-fundamental restrictions may be changed 
in the future by action of the directors or trustees without shareholder 
vote. 

BERGER NEW GENERATION FUND, BERGER SELECT FUND, BERGER SMALL COMPANY GROWTH 
FUND-Registered Trademark-, BERGER MID CAP GROWTH FUND AND BERGER BALANCED 
FUND

          Except as noted, the following fundamental restrictions apply to 
each of the Berger New Generation Fund, the Berger Select Fund, the Berger 
Small Company Growth Fund, the Berger Mid Cap Growth Fund and the Berger 
Balanced Fund.  The Fund may not:

          1.   ( Does not apply to the Berger Select Fund) With respect to 
75% of the Fund's total assets, purchase the securities of any one issuer 
(except U.S. government securities) if immediately after and as a result of 
such purchase (a) the value of the holdings of the Fund in the securities of 
such issuer exceeds 5% of the value of the Fund's total assets or (b) the 
Fund owns more than 10% of the outstanding voting securities of such issuer.


                                    -15-

<PAGE>

          2.   Invest in any one industry (other than U.S. government 
securities) 25% or more (more than 25%, in the case of the Berger Small 
Company Growth Fund) of the value of its total assets at the time of such 
investment.

          3.   Borrow money, except from banks for temporary or emergency 
purposes in amounts not to exceed 25% of the Fund's total assets (including 
the amount borrowed) taken at market value, nor pledge, mortgage or 
hypothecate its assets, except to secure permitted indebtedness and then only 
if such pledging, mortgaging or hypothecating does not exceed 25% of the 
Fund's total assets taken at market value.  When borrowings exceed 5% of the 
Fund's total assets, the Fund will not purchase portfolio securities.

          4.   Act as a securities underwriter (except to the extent the Fund 
may be deemed an underwriter under the Securities Act of 1933 in disposing of 
a security), issue senior securities (except to the extent permitted under 
the Investment Company Act of 1940), invest in real estate (although it may 
purchase shares of a real estate investment trust), or invest in commodities 
or commodity contracts except financial futures transactions, futures 
contracts on securities and securities indices and options on such futures, 
forward foreign currency exchange contracts, forward commitments or 
securities index put or call options.

          5.   Make loans, except that the Fund may enter into repurchase 
agreements and may lend portfolio securities in accordance with the Fund's 
investment policies.  The Fund does not, for this purpose, consider the 
purchase of all or a portion of an issue of publicly distributed bonds, bank 
loan participation agreements, bank certificates of deposit, bankers' 
acceptances, debentures or other securities, whether or not the purchase is 
made upon the original issuance of the securities, to be the making of a loan.

          In applying the industry concentration investment restriction (no. 
2 above), each Fund uses the industry groups used in the Data Monitor 
Portfolio Monitoring System of William O'Neil & Co. Incorporated.  Further, 
in implementing that restriction, the Berger Small Company Growth Fund 
intends not to invest in any one industry 25% or more of the value of its 
total assets at the time of such investment.

          The trustees have adopted additional non-fundamental investment 
restrictions for the Berger New Generation Fund, the Berger Select Fund, the 
Berger Small Company Growth Fund, the Berger Mid Cap Growth Fund and the 
Berger Balanced Fund.  These limitations may be changed by the trustees 
without a shareholder vote.  The non-fundamental investment restrictions 
include the following:

          1.   The Fund may not purchase securities on margin from a broker 
or dealer, except that the Fund may obtain such short-term credits as may be 
necessary for the clearance of transactions, and may not make short sales of 
securities, except that the Fund may make short sales if, at the time of the 
short sale, the Fund owns or has the right to acquire an equivalent kind and 
amount of the security being sold short at no additional cost (i.e., short 
sales "against the box").  This limitation shall not prohibit or restrict the 
Fund from entering into futures, forwards and options contracts or from 
making margin payments and other deposits in connection therewith.

          2.   The Fund may not purchase the securities of any other 
investment company, except by purchase in the open market involving no 
commission or profit to a sponsor or dealer (other than the customary 
broker's commission).

          3.   The Fund may not invest in companies for the purposes of 
exercising control of management.

                                -16-

<PAGE>

          4.   The Fund may not purchase any security, including any 
repurchase agreement maturing in more than seven days, which is not readily 
marketable, if more than 15% of the net assets of the Fund, taken at market 
value at the time of purchase would be invested in such securities.

          5.   Only for the purpose of hedging, the Fund may purchase and 
sell financial futures, forward foreign currency exchange contracts and put 
and call options, but no more than 5% of the Fund's net assets at the time of 
purchase may be invested in initial margins for financial futures 
transactions and premiums for options.  The Fund may only write call options 
that are covered and only up to 25% of the Fund's total assets.

          6.   The Fund may not purchase or sell securities on a when-issued 
or delayed delivery basis, if as a result more than 5% of its total assets 
taken at market value at the time of purchase would be invested in such 
securities.

BERGER SMALL CAP VALUE FUND

          The following fundamental restrictions apply to the Berger Small 
Cap Value Fund.  The Fund may not:

          1.   Issue senior securities as defined in the Investment Company 
Act of 1940.

          2.   Invest in companies for the purpose of acquiring control or 
management thereof.

          3.   Invest or hold securities of any issuer if the officers and 
trustees of the Fund and its advisor own individually more than one-half 
(1/2) of 1% of the securities of such issuer or together own more than 5% of 
the securities of such issuer.

          4.   Invest in other investment companies, except in connection 
with a plan of merger, consolidation, reorganization or acquisition of 
assets, or in the open market involving no commission or profit to a sponsor 
or dealer (other than a customary broker's commission).

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

          6.   Purchase securities of any company with a record of less than 
three (3) years continuous operation (including that of predecessors) if such 
purchase would cause the cost of the Fund's investments in all such companies 
to exceed 5% of the Fund's total assets.

          7.   Invest in securities (except those of the U.S. government or 
its agencies) of any issuer if immediately thereafter the Fund would then own 
more than 10% of that issuer's voting securities.

          8.   Loan cash or portfolio securities, except in connection with 
the acquisition of debt securities which the Fund's investment policies and 
restrictions permit it to purchase.

          9.   Borrow money in excess of 5% of the value of its assets and, 
then, only as a temporary measure for extraordinary or emergency purposes.

          10.  Pledge, mortgage or hypothecate any of its assets to secure a 
debt.

          11.  Purchase or sell real estate or any other interests in real 
estate (including real estate limited partnership interests).

                               -17-

<PAGE>

          12.  Purchase securities on margin or sell short.

          13.  Invest in commodities or commodity contracts.

          14.  Act as an underwriter of securities of other issuers or invest 
in portfolio securities which the Fund might not be free to sell to the 
public without registration of such securities under the Securities Act of 
1933 ("Restricted Securities").

          15.  Invest more than 10% of the value of its net assets in 
illiquid securities, including Restricted Securities, securities which are 
not readily marketable, repurchase agreements maturing in more than seven (7) 
days, written over-the-counter ("OTC") options and securities used as cover 
for written OTC options.

          16.  Invest in oil, gas or mineral leases. 

          17.  Invest more than 5% of the value of its net assets in warrants 
or more than 2% of its net assets in warrants that are not listed on the New 
York Stock Exchange, the American Stock Exchange, or the NASDAQ National 
Market System.

          18.  Invest more than 25% of the value of its assets, at the time 
of purchase, in securities of companies principally engaged in a particular 
industry, although the Fund may as a temporary defensive measure invest up to 
100% of its total assets in obligations issued or guaranteed by the U.S. 
government or its agencies.

          19.  With respect to 75% of the Fund's total assets, purchase the 
securities of any one issuer (except U.S. government securities) if 
immediately after and as a result of such purchase (a) the value of the 
holdings of the Fund in the securities of such issuer exceeds 5% of the value 
of the Fund's total assets or (b) the Fund owns more than 10% of the 
outstanding voting securities of such issuer.

          In applying the Fund's industry concentration restriction (number 
(18) above), the Fund uses the industry groups used in the Data Monitor 
Portfolio Monitoring System of William O'Neil & Co. Incorporated.

          The trustees have adopted additional non-fundamental investment 
restrictions for the Berger Small Cap Value Fund.  These limitations may be 
changed by the trustees without a shareholder vote.  The non-fundamental 
investment restrictions include the following:

          1.   Only for the purpose of hedging, the Fund may purchase and 
sell put and call options, but no more than 5% of the Fund's net assets at 
the time of purchase may be invested in premiums for options.  The Fund may 
only write call options that are covered and only up to 10% of the Fund's net 
assets.

          2.   The Fund may not purchase or sell securities on a when-issued 
or delayed delivery basis, if as a result more than 5% of its total assets 
taken at market value at the time of purchase would be invested in such 
securities.

          Investment restrictions that involve a maximum percentage of 
securities or assets will not be considered to be violated unless an excess 
over the percentage occurs immediately after, and is caused by, an 
acquisition or encumbrance of securities or assets of the Berger Small Cap 
Value Fund.

                               -18-

BERGER 100 FUND-Registered Trademark- AND BERGER GROWTH AND INCOME FUND

          The following fundamental restrictions apply to each of the Berger 
100 Fund and the Berger Growth and Income Fund.  The Fund may not:

          1.   Purchase the securities of any one issuer (except U.S. 
Government securities) if immediately after and as a result of such purchase

exceeds 5% of the value of the Fund's total assets or (b) the Fund owns more 
than 10% of the outstanding voting securities or of any class of securities 
of such issuer.

          2.   Purchase securities of any company with a record of less than

certificates of deposit, bankers' acceptances, debentures or other

the securities, to be the making of a loan.

contracts except, only for the purpose of hedging, (i) financial futures

          In applying the industry concentration investment restriction (no. 
3 above), the Funds use the industry groups used in the Data Monitor 
Portfolio Monitoring System of William O'Neil & Co. Incorporated.  Further, 
in implementing that restriction, each Fund intends not to invest in any one 
industry 25% or more of the value of its total assets at the time of such 
investment.

          The directors have adopted additional non-fundamental investment 
restrictions for the Berger 100 Fund and the Berger Growth and Income Fund. 
These limitations may be changed by the directors without a shareholder vote. 
The non-fundamental investment restrictions include the following:

          1.   Only for the purpose of hedging, the Fund may purchase and 
sell financial futures, forward foreign currency exchange contracts and put 
and call options, but no more than 5% of the Fund's net assets at the time of 
purchase may be invested in initial margins for financial futures 
transactions and premiums for options.  The Fund may only write call options 
that are covered and only up to 25% of the Fund's total assets.

          2.   The Fund may not purchase or sell securities on a when-issued 
or delayed delivery basis, if as a result more than 5% of its total assets 
taken at market value at the time of purchase would be invested in such 
securities.

          3.   The Fund may not purchase any security, including any 
repurchase agreement maturing in more than seven days, which is not readily 
marketable, if more than 15% of the net assets of the Fund, taken at market 
value at the time of purchase would be invested in such securities.

          4.   The Fund may not purchase securities on margin from a broker 
or dealer, except that the Fund may obtain such short-term credits as may be 
necessary for the clearance of transactions, and may not make short sales of 
securities, except that the Fund may make short sales if, at the time of the 
short sale, the Fund owns or has the right to acquire an equivalent kind and 
amount of the security being sold short at no additional cost (i.e., short 
sales "against the box").  This limitation shall not prohibit or restrict the 
Fund from entering into futures, forwards and options contracts or from 
making margin payments and other deposits in connection therewith.

BERGER/BIAM INTERNATIONAL FUND

          The Fund has adopted the investment policy that it may, 
notwithstanding any other fundamental or non-fundamental investment policy or 
restriction, invest all of its investable assets in the securities of another 
open-end investment company or series thereof with substantially the same 
investment objective, policies and limitations as the Fund.  This arrangement 
is commonly referred to as a master/feeder.

          All other fundamental and non-fundamental investment policies and 
restrictions of the Berger/BIAM International Fund and the Berger/BIAM 
International Portfolio (the "Portfolio") are identical.  Therefore, although 
the following investment restrictions refer to the Portfolio, they apply 
equally to the Fund. 

          The Portfolio has adopted certain fundamental restrictions on its 
investments and other activities, and none of these restrictions may be 
changed without the approval of (i) 67% or more of the voting securities of 
the Portfolio present at a meeting of shareholders thereof if the holders of 
more than 50% of the outstanding voting securities are present or represented 
by proxy, or (ii) more than 50% of the outstanding voting securities of the 
Portfolio.  Whenever the Fund is requested to vote on a change in the 
investment restrictions of the Portfolio, the Fund will hold a meeting of its 
shareholders and will cast its votes as instructed by the shareholders.

          The following fundamental restrictions apply to the Portfolio.  The 
Portfolio may not:

                                  -20-

<PAGE>

          1.   With respect to 75% of the Portfolio's total assets, purchase 
the securities of any one issuer (except U.S. government securities) if 
immediately after and as a result of such purchase (a) the value of the 
holdings of the Portfolio in the securities of such issuer exceeds 5% of the 
value of the Portfolio's total assets or (b) the Portfolio owns more than 10% 
of the outstanding voting securities of such issuer.

          2.   Invest in any one industry (other than U.S. government 
securities) 25% or more of the value of its total assets at the time of such 
investment.

          3.   Borrow money, except from banks for temporary or emergency 
purposes in amounts not to exceed 25% of the Portfolio's total assets 
(including the amount borrowed) taken at market value, nor pledge, mortgage 
or hypothecate its assets, except to secure permitted indebtedness and then 
only if such pledging, mortgaging or hypothecating does not exceed 25% of the 
Portfolio's total assets taken at market value.  When borrowings exceed 5% of 
the Portfolio's total assets, the Portfolio will not purchase portfolio 
securities.

          4.   Act as a securities underwriter (except to the extent the 
Portfolio may be deemed an underwriter under the Securities Act of 1933 in 
disposing of a security), issue senior securities (except to the extent 
permitted under the Investment Company Act of 1940), invest in real estate 
(although it may purchase shares of a real estate investment trust), or 
invest in commodities or commodity contracts except financial futures 
transactions, futures contracts on securities and securities indices and 
options on such futures, forward foreign currency exchange contracts, forward 
commitments or securities index put or call options.

          5.   Make loans, except that the Portfolio may enter into 
repurchase agreements and may lend portfolio securities in accordance with 
the Portfolio's investment policies.  The Portfolio does not, for this 
purpose, consider the purchase of all or a portion of an issue of publicly 
distributed bonds, bank loan participation agreements, bank certificates of 
deposit, bankers' acceptances, debentures or other securities, whether or not 
the purchase is made upon the original issuance of the securities, to be the 
making of a loan.

          In applying the industry concentration investment restriction (no. 
2 above), the Portfolio uses the industry groups designated by the Financial 
Times World Index Service.

          The trustees have adopted additional non-fundamental investment 
restrictions for the Portfolio.  These limitations may be changed by the 
trustees without a shareholder vote.  The non-fundamental investment 
restrictions include the following:

          1.   With respect to 100% of the Portfolio's total assets, the 
Portfolio may not purchase the securities of any one issuer (except U.S. 
government securities) if immediately after and as a result of such purchase 
(a) the value of the holdings of the Portfolio in the securities of such 
issuer exceeds 5% of the value of the Portfolio's total assets or (b) the 
Portfolio owns more than 10% of the outstanding voting securities of such 
issuer.

          2.   The Portfolio may not purchase securities on margin from a 
broker or dealer, except that the Portfolio may obtain such short-term 
credits as may be necessary for the clearance of transactions, and may not 
make short sales of securities.  This limitation shall not prohibit or 
restrict the Portfolio from entering into futures, forwards and options 
contracts or from making margin payments and other deposits in connection 
therewith.

          3.   The Portfolio may not purchase the securities of any other 
investment company, except by purchase in the open market involving no 
commission or profit to a sponsor or dealer (other than the customary 
broker's commission). 

                             -21-

<PAGE>

          4.   The Portfolio may not invest in companies for the purposes of 
exercising control of management.

          5.   The Portfolio may not purchase any security, including any 
repurchase agreement maturing in more than seven days, which is not readily 
marketable, if more than 15% of the net assets of the Portfolio, taken at 
market value at the time of purchase would be invested in such securities.

          6.   The Portfolio may not enter into any futures, forwards or 
options, except that only for the purpose of hedging, the Portfolio may enter 
into forward foreign currency exchange contracts with stated contract values 
of up to the value of the Portfolio's assets.

          7.   The Portfolio may not purchase or sell securities on a 
when-issued or delayed delivery basis, if as a result more than 5% of its net 
assets taken at market value at the time of purchase would be invested in 
such securities.

          Directors or trustees may elect to defer receipt of all or a

Funds. Under the plan, deferred fees are credited to an account and adjusted 
thereafter to reflect the investment experience of whichever of the Berger 
Funds (or approved money market funds) is designated by the director or 
trustee for this purpose.  Pursuant to an SEC exemptive order, the Funds are 
permitted to purchase shares of the designated funds in order to offset their 
obligation to the directors/trustees participating in the plan.  Purchases 
made pursuant to the plan are excepted from any otherwise applicable 
investment restriction limiting the purchase of securities of any other 
investment company.  A Fund's obligation to make payments of deferred fees 
under the plan is a general obligation of the Fund.


          As of April 22, 1998, the officers and directors/trustees of the 
Funds as a group owned of record or beneficially approximately 4.65% of the 
Berger Mid Cap Growth Fund, approximately 4.22% of the Berger Select Fund,

Berger New Generation Fund, the Berger Select Fund, the Berger Small Company

<PAGE>

administrator and is responsible for such functions as monitoring compliance 
with all applicable federal and state laws.


          Berger Associates has been in the investment advisory business for 
over 20 years.  It serves as investment advisor or sub-advisor to mutual 
funds and institutional investors and had assets under management of more 
than $3.9 billion as of September 30, 1997.  Berger Associates is a 
wholly-owned subsidiary of Kansas City Southern Industries, Inc. ("KCSI").  
KCSI is a publicly traded holding company with principal operations in rail 
transportation, through its subsidiary The Kansas City Southern Railway 
Company, and financial asset management businesses.  KCSI also owns 
approximately 41% of the outstanding shares of DST Systems, Inc. ("DST"), a 
publicly traded information and transaction processing company which acts as 
the Funds' sub-transfer agent.


BBOI WORLDWIDE LLC - INVESTMENT ADVISOR

          BBOI Worldwide LLC ("BBOI Worldwide"), 210 University Boulevard, 
Denver, CO 80206, is the investment advisor to the Berger/BIAM International 
Portfolio (the "Portfolio"), in which all the investable assets of the 
Berger/BIAM International Fund are invested.  BBOI Worldwide oversees, 
evaluates and monitors the investment advisory services provided to the 
Portfolio by the Portfolio's sub-advisor and is responsible for furnishing 
general business management and administrative services to the Portfolio.

          BBOI Worldwide is a Delaware limited liability company formed in 
1996. Since BBOI Worldwide was only recently formed, it has only limited 
prior experience as an investment advisor.  However, BBOI Worldwide is a 
joint venture between Berger Associates and Bank of Ireland Asset Management 
(U.S.) Limited ("BIAM"), the sub-advisor to the Portfolio, which have both 
been in the investment advisory business for many years.

          Berger Associates and BIAM each own a 50% membership interest in 
BBOI Worldwide  and each have an equal number of representatives on BBOI 
Worldwide's Board of Managers.  Berger Associates' role in the joint venture 
is to provide administrative services, and BIAM's role is to provide 
international and global investment management expertise.  Agreement of 
representatives of both Berger Associates and BIAM is required for all 
significant management decisions.

BANK OF IRELAND ASSET MANAGEMENT (U.S.) LIMITED - SUB-ADVISOR

          As permitted in its Investment Advisory Agreement with the 
Berger/BIAM International Portfolio, BBOI Worldwide has delegated day-to-day 
investment management responsibility for the Portfolio to BIAM.  As 
sub-advisor, BIAM manages the investments in the Portfolio and determines 
what securities and other investments will be purchased, retained, sold or 
loaned, consistent with the investment objective and policies established by 
the trustees.  BIAM's main offices are at 26 Fitzwilliam Place, Dublin 2, 
Ireland.  BIAM maintains a representative office at 20 Horseneck Lane, 
Greenwich, CT 06830.  BIAM is an indirect wholly-owned subsidiary of Bank of 
Ireland, a publicly traded, diversified financial services group with 
business operations worldwide.  Bank of Ireland provides investment 
management services through a network of related companies, including BIAM 
which serves primarily institutional clients in the United States and Canada. 
 Bank of Ireland and its affiliates managed assets for clients worldwide in 
excess of $25 billion as of September 30, 1997.

          Bank of Ireland or its affiliates may have deposit, loan or other 
commercial or investment banking relationships with the issuers of securities 
which may be purchased by the Portfolio, including outstanding loans to such 
issuers which could be repaid in whole or in part with the proceeds of 
securities purchased by the Portfolio.  Federal law prohibits BIAM, in making 
investment decisions, from using material non-public information in its 
possession or in the possession of any of its affiliates.  In addition, in 
making investment decisions for the Portfolio, BIAM will not take 

                                -28-

<PAGE>


into consideration whether an issuer of securities proposed for purchase or 
sale by the Portfolio is a customer of Bank of Ireland or its affiliates.

          The Glass-Steagall Act prohibits a depository institution and 
certain affiliates from underwriting or distributing most securities and from 
affiliating with businesses engaged in certain similar activities.  BIAM 
believes that it may perform the services for the Fund contemplated by the 
Sub-Advisory Agreement between BBOI Worldwide and BIAM consistent with the 
Glass-Steagall Act and other applicable banking laws and regulations.  
However, future changes in either Federal or state statutes and regulations 
concerning the permissible activities of banks and their affiliates, as well 
as future judicial or administrative decisions or interpretations of present 
and future statutes and regulations, might prevent BIAM from continuing to 
perform those services for the Fund.  If the circumstances described above 
should change, the trustees of the Fund and the Portfolio would review the 
relationships with BIAM and consider taking all actions appropriate under the 
circumstances. 

PERKINS, WOLF, MCDONNELL & COMPANY - SUB-ADVISOR

          Perkins, Wolf, McDonnell & Company ("PWM"), 53 West Jackson 
Boulevard, Suite 818, Chicago, Illinois 60604, has been engaged as the 
investment sub-advisor for the Berger Small Cap Value Fund.  PWM was 
organized in 1980 under the name Mac-Per-Wolf Co. to operate as a securities 
broker-dealer.  In September 1983, it changed its name to Perkins, Wolf, 
McDonnell & Company.  PWM is a member of the National Association of 
Securities Dealers, Inc. (the "NASD") and, in 1984, became registered as an 
investment adviser with the SEC.

          PWM was the Fund's investment advisor from the date the Fund 
commenced operations in 1985 to February 1997.  PWM became the investment 
sub-advisor to the Fund on February 14, 1997, following shareholder approval 
of a new Sub-Advisory Agreement between Berger Associates as advisor and PWM 
as sub-advisor.

          Robert H. Perkins is the individual who is primarily responsible 
for the day-to-day management of the Fund's investments.  Mr. Perkins has 
held such responsibility and has been employed by PWM since the Fund 
commenced operations in 1985.  Mr. Perkins owns 49% of PWM's outstanding 
common stock and serves as President and a director of PWM.  Gregory E. Wolf 
owns 20% of PWM's outstanding common stock and serves as Treasurer and a 
director of PWM. 

INVESTMENT ADVISORY AGREEMENTS

          Under the Investment Advisory Agreements between each Fund and its 
advisor, the advisor is generally responsible for furnishing continuous 
advice and recommendations as to the acquisition, holding or disposition of 
securities or other assets which each Fund may own or contemplate acquiring 
from time to time.  Under the Agreements, the advisor is compensated for its 
services by the payment of a fee at the following annual rates, calculated as

(1)     Berger Associates has voluntarily agreed to waive its advisory fee to 
the extent that the Berger New Generation Fund's normal operating expenses in 
any fiscal year, including the management fee and the 12b-1 fee, but 
excluding brokerage commissions, interest, taxes and extraordinary expenses, 
exceed 1.90% of the Fund's average daily net assets for that fiscal year.

(2)     Fund is sub-advised by PWM.  See text preceding and following table. 
The investment advisory fee is allocated among the Investor Shares and other 
classes of the Fund on the basis of net assets attributable to each such 
class.

(3)     Berger Associates has voluntarily agreed to waive its advisory fee to 
the extent that the Fund's normal operating expenses in any fiscal year, 
including the management fee, but excluding the 12b-1 fee, brokerage 
commissions, interest, taxes and extraordinary expenses, exceed 2-1/2% of the 
first $30,000,000 of average daily net assets, plus 2% of the next 
$70,000,000, plus 1-1/2% of the balance of the average daily net assets of 
the Fund for that fiscal year. 


(4)    The Berger/BIAM International Fund bears its pro rata portion of the 
fee paid by the Berger/BIAM International Portfolio to BBOI Worldwide as the 
advisor.  The Fund is sub-advised by BIAM.  See text preceding and following 
table.   BBOI Worldwide has agreed  to waive the investment advisory fee paid 
by the Portfolio under the Investment Advisory Agreement to the extent that 
the Portfolio's normal operating expenses in any fiscal year, including the 
investment advisory fee and custodian fees, but excluding brokerage 
commissions, interest, taxes and extraordinary expenses, exceed 1.00% of the 
Portfolio's average daily net assets for that fiscal year.  Any reduction in 
the advisory fee paid by the Portfolio will also reduce the pro rata share of 
the advisory fee borne indirectly by the Berger/BIAM International Fund. 


(5)     Berger Associates has voluntarily agreed to waive its advisory fee to 
the extent that the Berger Balanced Fund's normal operating expenses in any 
fiscal year, including the investment advisory fee and the 12b-1 fee, but 
excluding brokerage commissions, interest, taxes and extraordinary expenses, 
exceed 1.50% of the Fund's average daily net assets for that fiscal year.    

          Each Fund's current Investment Advisory Agreement will continue in 
effect until the last day of April, 1998 or 1999, and thereafter from year to 
year if such continuation is specifically approved at least annually by the 
directors or trustees or by vote of a majority of the outstanding shares of 
the Fund and in either case by vote of a majority of the directors or 
trustees who are not "interested persons" (as that term is defined in the 
1940 Act) of the Fund or the advisor.  Each Agreement is subject to 
termination by the Fund or the advisor on 60 days' written notice, and 
terminates automatically in the event of its assignment.

          Under the Sub-Advisory Agreement between the advisor and the 
sub-advisors for the Berger/BIAM International Portfolio and the Berger Small 
Cap Value Fund, the sub-advisor is responsible for day-to-day investment 
management. The sub-advisor manages the investments and determines what 
securities and other investments will be acquired, held or disposed of, 
consistent with the investment objective and policies established by the 
trustees.  No fees are paid directly to the sub-advisors by the Funds.  PWM, 
as the sub-advisor of the Berger Small Cap Value Fund, receives from the 
advisor a fee at the annual rate of 0.90% of the first $75 million of average 
daily net asset of the Fund, 0.50% of the next $125 million, and 0.20% of any 
amounts in excess of $200 million. BIAM, as the sub-advisor of the 
Berger/BIAM International Portfolio, receives from the advisor a fee at the 
annual rate of 0.45% of the average daily net assets of the Portfolio.  
During certain periods, BIAM may voluntarily waive all or a portion of its 
fee under the Sub-Advisory Agreement, which will not affect the fee paid by 
the Portfolio to the advisor.

                                  -30-

<PAGE>

          The Sub-Advisory Agreements for the Berger Small Cap Value Fund and
the Berger/BAM International Portfolio will continue in effect until April 1998,
and thereafter from year to year if such continuation is specifically approved
at least annually by the trustees or by vote of a majority of the outstanding
shares of the Fund and in either case by vote of a majority of the trustees of
the Fund who are not "interested persons" (as that term is defined in the
Investment Company Act of 1940) of the Fund or the advisor or the sub-advisor. 
The Sub-Advisory Agreements are subject to termination by the Fund or the 
sub-advisor on 60 days' written notice, and terminate automatically in the 
event of their assignment and in the event of termination of the related 
Investment Advisory Agreement.

OTHER ARRANGEMENTS BETWEEN BERGER ASSOCIATES AND PWM 

          Berger Associates and PWM entered into an Agreement, dated November
18, 1996 (the "November 18 Agreement"), under which, among other things, PWM
agreed that, so long as Berger Associates acts as the advisor to the Berger
Small Cap Value Fund and PWM provides sub-advisory or other services in
connection with the Fund, PWM will not manage or provide advisory services to
any registered investment company that is in direct competition with the Fund.  

          The November 18 Agreement also provides that at the end of the first
five years under the Sub-Advisory Agreement for that Fund (or at such earlier
time if the Sub-Advisory Agreement is terminated or not renewed by the trustees
other than for cause), Berger Associates and PWM will enter into a consulting
agreement for PWM to provide consulting services to Berger Associates with
respect to the Fund, subject to any requisite approvals under the Investment
Company Act of 1940.  Under the Consulting Agreement, PWM would provide training
and assistance to Berger Associates analysts and marketing support appropriate
to the Fund and would be paid a fee at an annual rate of 0.10% of the first $100
million of average daily net assets of the Fund, 0.05% of the next $100 million
and 0.02% on any part in excess of $200 million.  No part of the consulting fee
would be borne by the Fund.

TRADE ALLOCATIONS

          Investment decisions for each Fund and other accounts advised by the
Funds' advisors and sub-advisors are made independently with a view to achieving
each of their respective investment objectives and after consideration of such
factors as their current holdings, availability of cash for investment and the
size of their investments generally.  However, certain investments may be
appropriate for a Fund and one or more such accounts.  If a Fund and other
accounts advised by a Fund's advisor or sub-advisor are contemporaneously
engaged in the purchase or sale of the same security, the orders may be
aggregated and/or the transactions averaged as to price and allocated equitably
to the Fund and each participating account.  While in some cases, this policy
might adversely affect the price paid or received by a Fund or other
participating accounts, or the size of the position obtained or liquidated, the
advisor or sub-advisor will aggregate orders if it believes that coordination of
orders and the ability to participate in volume transactions will result in the
best overall combination of net price and execution.

RESTRICTIONS ON PERSONAL TRADING

          Berger Associates permits its directors, officers, employees and other
access persons (as defined below) of Berger Associates ("covered persons") to
purchase and sell securities for their own accounts in accordance with
provisions governing personal investing in Berger Associates' Code of Ethics. 
The Code requires all covered persons to conduct their personal securities
transactions in a manner which does not operate adversely to the interests of
the Funds or Berger Associates' other advisory clients.  Directors and officers
of Berger Associates (including those who also serve as directors or trustees of
the Funds), investment personnel and other designated covered persons deemed to
have access to current trading information ("access persons") are required to
pre-clear all transactions in securities not otherwise exempt under the Code. 
Requests for authority to trade will be denied pre-clearance when, among other
reasons, the proposed personal transaction would be contrary to the 

                                    -31-
<PAGE>

provisions of the Code or would be deemed to adversely affect any transaction 
then known to be under consideration for or currently being effected on 
behalf of any client account, including the Funds.

          In addition to the pre-clearance requirements described above, the
Code subjects those covered persons deemed to be access persons to various
trading restrictions and reporting obligations.  All reportable transactions are
reviewed for compliance with Berger Associates' Code.  Those covered persons
also may be required under certain circumstances to forfeit their profits made
from personal trading.  The Code is administered by Berger Associates and the
provisions of the Code are subject to interpretation by and exceptions
authorized by its board of directors.

          PWM has adopted a Code of Ethics which is substantially similar to the
Code adopted by Berger Associates.  BBOI Worldwide has also adopted a Code of
Ethics substantially similar to the Code adopted by Berger Associates covering
all board members, officers, employees and other access persons (as defined
below) of BBOI Worldwide who are not also covered by an approved Code of Ethics
of an affiliated person who is an investment advisor ("covered persons"). At
present, there are no persons who would be covered by BBOI Worldwide's Code of
Ethics who are not also covered by the Code of Ethics of Berger Associates or
BIAM, which are both investment advisors affiliated with BBOI Worldwide. 

          BIAM has adopted a Code of Ethics which restricts its officers,
employees and other staff from personal trading in specified circumstances,
including among others prohibiting participation in initial public offerings,
prohibiting dealing in a security for the seven days before and after any trade
in that security on behalf of clients, prohibiting trading in a security while
an order is pending for any client on that same security, and requiring profits
from short-term trading in securities (purchase and sale within a 60-day period)
to be forfeited.  In addition, staff of BIAM must report all of their personal
holdings in securities annually and must disclose their holdings in any private
company if an investment in that same company is being considered for clients. 
Staff of BIAM are required to pre-clear all transactions in securities not
otherwise exempt under the Code of Ethics and must instruct their broker to
provide BIAM with duplicate confirmations of all such personal trades.

5.        EXPENSES OF THE FUNDS

ALL FUNDS EXCEPT THE BERGER/BIAM INTERNATIONAL FUND

          In addition to paying an investment advisory fee to its advisor, each
Fund (other than the Berger/BIAM International Fund) pays all of its expenses
not assumed by its advisor, including, but not limited to, custodian and
transfer agent fees, legal and accounting expenses, administrative and record
keeping expenses, interest charges, federal and state taxes, costs of share
certificates, expenses of shareholders' meetings, compensation of directors or
trustees who are not interested persons of Berger Associates, expenses of
printing and distributing reports to shareholders and federal and state
administrative agencies, and all expenses incurred in connection with the
execution of its portfolio transactions, including brokerage commissions on
purchases and sales of portfolio securities, which are considered a cost of
securities of each Fund.  Each Fund also pays all expenses incurred in complying
with all federal and state laws and the laws of any foreign country applicable
to the issue, offer or sale of shares of the Fund, including, but not limited
to, all costs involved in preparing and printing prospectuses for shareholders
of the Fund. 

          Under a separate Administrative Services Agreement with respect to
each of such Funds, Berger Associates performs certain administrative and
recordkeeping services not otherwise performed by the Fund's custodian and
recordkeeper, including the preparation of financial statements and reports to
be filed with the Securities and Exchange Commission and state regulatory
authorities.  Each Fund pays Berger Associates a fee at an annual rate of 0.01%
of its average daily net assets for such services.  These fees are in addition
to the investment advisory fees paid under the Investment Advisory 

                                    -32-
<PAGE>

Agreement. The administrative services fees may be changed by the directors 
or trustees without shareholder approval.

          The following tables show the advisory fees and administrative
services fees paid by each of such Funds to Berger Associates for the periods
indicated and the amount of such fees waived on account of excess expenses under
applicable expense limitations.

          Each of the Funds has appointed Investors Fiduciary Trust Company
("IFTC"), 127 W. 10th Street, Kansas City, MO 64105, as its recordkeeping and
pricing agent.  In addition, IFTC also serves as the Funds' custodian, transfer
agent and dividend disbursing agent.  IFTC has engaged DST  Systems, Inc.
("DST"), P.O. Box 419958, Kansas City, MO 64141, as sub-agent to provide
transfer agency and dividend disbursing services for the Funds.  Approximately
41% of the outstanding shares of DST are owned by KCSI.  The addresses and
telephone numbers for DST set forth in the Prospectus and this Statement of
Additional Information should be used for correspondence with the transfer
agent.

          As recordkeeping and pricing agent, IFTC calculates the daily net
asset value of each Fund and performs certain accounting and recordkeeping
functions required by the Funds.  The Funds 

                                    -34-
<PAGE>

pay IFTC a monthly base fee plus an asset-based fee.  IFTC is also reimbursed 
for certain out-of-pocket expenses.

          IFTC, as custodian, and its subcustodians have custody and provide for
the safekeeping of the Funds' securities and cash, and receive and remit the
income thereon as directed by the management of the Funds.  The custodian and
subcustodians do not perform any managerial or policy-making functions for the
Funds.  For its services as custodian, IFTC receives an asset-based fee plus
certain transaction fees and out-of-pocket expenses.


          As transfer agent and dividend disbursing agent, IFTC (through DST,
as sub-agent) maintains all shareholder accounts of record; assists in 
mailing all reports, proxies and other information to the Funds' 
shareholders; calculates the amount of, and delivers to the Funds' 
shareholders, proceeds representing all dividends and distributions; and 
performs other related services.  For these services, IFTC receives a fee 
from the Funds at an annual rate of $14.00 per open Fund shareholder account, 
subject to preset volume discounts, plus certain transaction fees and fees 
for closed accounts, and is reimbursed for out-of-pocket expenses, which fees 
in turn are passed through to DST as sub-agent.


          All of IFTC's fees are subject to reduction pursuant to an agreed
formula for certain earnings credits on the cash balances of the Funds. 
Earnings credits received by each Fund can be found on the Fund's Statement of
Operations in the Annual Report incorporated by reference into this Statement of
Additional Information.

BERGER/BIAM INTERNATIONAL FUND

          The Berger/BIAM International Fund is allocated and bears indirectly
its pro rata share of the aggregate annual operating expenses of the 
Berger/BIAM International Portfolio, since all of the investable assets of 
the Fund are invested in the Portfolio.  

          Expenses of the Portfolio include, among others, its pro rata share of
the expenses of Berger/BIAM Worldwide Portfolios Trust, of which the Portfolio
is a series, such as: expenses of registering the Trust with securities
authorities; the compensation of its independent trustees; expenses of preparing
reports to investors and to governmental offices and commissions; expenses of
meetings of investors and trustees of the Trust; legal fees; and insurance
premiums of the Trust.  Expenses of the Portfolio also include, among others,
the fees payable to the advisor under the Investment Advisory Agreement;
expenses connected with the execution of portfolio transactions, including
brokerage commissions on purchases and sales of portfolio securities (which are
considered a cost of securities of the Portfolio); custodian fees; auditors'
fees; interest and taxes imposed on the Portfolio; transfer agent, recordkeeping
and pricing agent fees; and such other non-recurring and extraordinary items as
may arise from time to time.

          Expenses of the Berger/BIAM International Fund include, among others,
its pro rata share of the expenses of the Berger/BIAM Worldwide Funds Trust, 
of which the Fund is a series, such as: expenses of registering the Trust 
with securities authorities; expenses of meetings of the shareholders of the 
Trust; and legal fees.  Expenses of the Fund also include, among others, 
registration and filing fees incurred in registering shares of the Fund with 
securities authorities; 12b-1 fees; taxes imposed on the Fund; the fee 
payable to the Advisor under the Administrative Services Agreement; and such

          SERVICE ARRANGEMENTS FOR THE FUND.  Under an Administrative Services
Agreement with the Berger/BIAM International Fund, BBOI Worldwide serves as the
administrator of the Fund.  In this capacity, it is responsible for
administering and managing all aspects of the Fund's day-to-day operations,
subject to the oversight of the trustees of the Fund.  BBOI Worldwide is
responsible, at its expense, for furnishing (or procuring other parties to
furnish) all administrative services reasonably necessary for the operation of
the Fund, including recordkeeping and pricing services, custodian services,
transfer agency

                                    -35-

<PAGE>

and dividend disbursing services, tax and audit services, insurance, 
printing and mailing to shareholders of prospectuses and other required 
communications, and certain other administrative and recordkeeping services, 
such as coordinating matters relating to the operations of the Fund, 
monitoring the Fund's status as a "regulated investment company" under the 
Internal Revenue Code, coordinating registration of sufficient Fund shares 
under federal and state securities laws, arranging for and supervising the 
preparation of registration statements, tax returns, proxy materials, 
financial statements and reports for filing with regulatory authorities and 
distribution to shareholders of the Fund.  Under the Administrative Services 
Agreement, the Fund pays BBOI Worldwide a fee at an annual rate equal to the 
lesser of (i) 0.45% of its average daily net assets, or (ii) BBOI Worldwide's 
annual cost to provide or procure these services (including the fees of any 
services providers whose services are procured by BBOI Worldwide), plus an 
additional 0.02% of the Fund's average daily net assets.  The trustees of the 
Fund regularly review amounts paid to and expenditures incurred by BBOI 
Worldwide pursuant to the Administrative Services Agreement.  In addition, in 
the event that BBOI Worldwide's duties under the Administrative Services 
Agreement are delegated to another party, BBOI Worldwide may take into 
account, in calculating the cost of such services, only the costs incurred by 
such other party in discharging the delegated duties.

          Under a Sub-Administration Agreement between BBOI Worldwide and Berger
Associates, Berger Associates has been delegated the responsibility to perform
certain of the administrative and recordkeeping services required under the
Administrative Services Agreement and to procure, at BBOI Worldwide's expense,
third parties to provide the services not provided by Berger Associates.  Under
the Sub-Administration Agreement, Berger Associates is paid a fee by BBOI
Worldwide of 0.25% of the Fund's average daily net assets for its services. 
During certain periods, Berger Associates may voluntarily waive all or a portion
of its fee from BBOI Worldwide, which will not affect the fee paid by the Fund
to BBOI Worldwide under the Administrative Services Agreement.  


          IFTC has been appointed to provide recordkeeping and pricing services
to the Fund, including calculating the daily net asset value of the Fund, and to
perform certain accounting and recordkeeping functions that it requires.  In
addition, IFTC has been appointed to serve as the Fund's custodian, transfer
agent and dividend disbursing agent.  IFTC has engaged DST as sub-transfer agent
to provide transfer agency and dividend disbursing services for the Fund.  The
fees of Berger Associates, IFTC and DST are all paid by BBOI Worldwide. 
Approximately 41% of the outstanding shares of DST are owned by KCSI, which also
owns 100% of the outstanding shares of Berger Associates.


          SERVICE ARRANGEMENTS FOR THE PORTFOLIO.  Under the Investment Advisory
Agreement between BBOI Worldwide and the Berger/BIAM International Portfolio, in
addition to providing investment advisory services, BBOI Worldwide is
responsible for providing or arranging for all managerial and administrative
services necessary for the operations of the Portfolio.  BBOI Worldwide is
responsible for providing certain of these services at its own expense, such as
compliance monitoring and preparing investor communications, which have been
delegated to Berger Associates as part of the Sub-Administration Agreement
discussed above.  Other services are procured from third party service providers
at the Portfolio's own expense, such as custody, recordkeeping and pricing
services.  

          The Portfolio has appointed IFTC as recordkeeping and pricing agent to
calculate the daily net asset value of the Portfolio and to perform certain
accounting and recordkeeping functions required by the Portfolio.  In addition,
the Portfolio has appointed IFTC as its custodian and transfer agent.  IFTC has
engaged State Street Bank and Trust Company ("State Street"), P.O. Box 351,
Boston, MA 02101, as sub-custodian for the Portfolio.  For custodian,
recordkeeping and pricing services, the Portfolio pays fees directly to IFTC
based on a percentage of its net assets, subject to certain minimums, and
reimburses IFTC for certain out-of-pocket expenses.

          For the period October 11, 1996 (commencement of operations) through
the end of the Portfolio's first fiscal year on September 30, 1997, the
Portfolio paid BBOI Worldwide $560,000 for its services under the Investment
Advisory Agreement, which was reduced by a $61,000 advisory fee

                                    -36-
<PAGE>

waiver.  The investment advisory fee paid by the Portfolio is borne 
indirectly pro rata by the Fund and the other mutual funds invested in the 
Portfolio.  In addition, during the same period, the Fund paid BBOI Worldwide 
$63,000 for its services under the Administrative Services Agreement.
 
          As noted above with respect to the other Berger Funds, all of IFTC's
fees are subject to reduction pursuant to an agreed formula for certain earnings
credits on the cash balances maintained with it as custodian.  Earnings credits
received by the Portfolio can be found on the Portfolio's Statement of
Operations in the Annual Report incorporated by reference into this Statement of
Additional Information.

12b-1 PLANS

          Each of the Funds has adopted a 12b-1 plan (the "Plan") pursuant to
Rule 12b-1 under the Investment Company Act of 1940, which provides for the
payment to Berger Associates of a 12b-1 fee of 0.25% per annum of the Fund's
average daily net assets to finance activities primarily intended to result in
the sale of Fund shares.  The expenses paid by Berger Associates may include,
but are not limited to, payments made to, and costs incurred by, a Fund's
principal underwriter in connection with the distribution of Fund shares,
including payments made to and expenses of officers and registered
representatives of the Distributor; payments made to and expenses of other
persons (including employees of Berger Associates) who are engaged in, or
provide support services in connection with, the distribution of Fund shares,
such as answering routine telephone inquiries and processing shareholder
requests for information; compensation (including incentive compensation and/or
continuing compensation based on the amount of customer assets maintained in a
Fund) paid to securities dealers, financial institutions and other organizations
which render distribution and administrative services in connection with the
distribution of Fund shares, including services to holders of Fund shares and
prospective investors; costs related to the formulation and implementation of
marketing and promotional activities, including direct mail promotions and
television, radio, newspaper, magazine and other mass media advertising; costs
of printing and distributing prospectuses and reports to prospective
shareholders of Fund shares; costs involved in preparing, printing and
distributing sales literature for Fund shares; costs involved in obtaining
whatever information, analyses and reports with respect to market and
promotional activities on behalf of a Fund relating to Fund shares that Berger
Associates deems advisable; and such other costs relating to Fund shares as the
Fund may from time to time reasonably deem necessary or appropriate in order to
finance activities primarily intended to result in the sale of Fund shares. 
Such 12b-1 fee payments are to be made by each Fund to Berger Associates with
respect to each fiscal year of the Fund without regard to the actual
distribution expenses incurred by Berger Associates in such year; that is, if
the distribution expenditures incurred by Berger Associates are less than the
total of such payments in such year, the difference is not to be reimbursed to
the Fund by Berger Associates, and if the distribution expenditures incurred by
Berger Associates are more than the total of such payments, the excess is not to
be reimbursed to Berger Associates by the Fund.

          From time to time a Fund may engage in activities which jointly
promote the sale of Fund shares and other funds that are or may in the future be
advised or administered by Berger Associates, which costs are not readily
identifiable as related to any one fund.  In such cases, Berger Associates
allocates the cost of the activity among the funds involved on the basis of
their respective net assets, unless otherwise directed by the directors or
trustees.

          The current 12b-1 Plans will continue in effect until the end of April
1998, and from year to year thereafter if approved at least annually by each
Fund's directors or trustees and those directors or trustees who are not
interested persons of the Fund and have no direct or indirect financial interest
in the operation of the Plan or any related agreements by votes cast in person
at a meeting called for such purpose.  The Plans may not be amended to increase
materially the amount to be spent on distribution of Fund shares without
shareholder approval.

(1)     The Berger Balanced Fund did not commence operations until 
September 30, 1997.  The Berger Select Fund and the Berger Mid Cap Growth 
Fund did not commence operations until December 31, 1997.

(2)     See text following table.

(3)     The Berger Small Cap Value Fund has adopted a 12b-1 Plan only with
respect to the Investor Shares, the class of shares of the Fund covered by this
SAI.

          Effective November 17, 1997, and for so long as the Berger Small
Company Growth Fund remains closed to new investors, Berger Associates has
voluntarily agreed to waive the 12b-1 fee paid by that Fund to the extent the
fee is not utilized by Berger Associates to provide, or to compensate other
companies for providing, shareholder services to Fund shareholders in connection
with the distribution of Fund shares. 

OTHER EXPENSE INFORMATION

          The directors or trustees of each of the Funds have authorized
portfolio transactions to be placed on an agency basis through DST Securities,
Inc. ("DSTS"), a wholly-owned broker-dealer subsidiary of DST.  When
transactions are effected through DSTS, the commission received by DSTS is
credited against, and thereby reduces, certain operating expenses that the Fund
would otherwise be obligated to pay.  No portion of the commission is retained
by DSTS.  See Section 6--Brokerage Policy for further information concerning the
expenses reduced as a result of these arrangements.  DSTS may be considered an
affiliate of Berger Associates due to the ownership interest of KCSI in both
DSTS and Berger Associates.  

          The Funds and/or their advisors have entered into arrangements with
certain brokerage firms and other companies(such as recordkeepers and
administrators) to provide administrative services (such as sub-transfer agency,
recordkeeping, shareholder communications,  sub-accounting and/or other
services) to investors purchasing shares of the Funds through those firms or
companies.  A Fund's advisor or a Fund (if approved by its directors or
trustees) may pay fees to these companies for their services.  These companies
may also be appointed as agents for or authorized by the Funds to accept on
their behalf purchase and redemption requests that are received in good order. 
Subject to Fund approval, certain of these companies may be authorized to
designate other entities to accept purchase and redemption orders on behalf of
the Funds.

DISTRIBUTOR

          The distributor (principal underwriter) of each Fund's shares is
Berger Distributors, Inc. (the "Distributor"), 210 University Boulevard, Suite
900, Denver, CO 80206.  The Distributor may be reimbursed by Berger Associates
for its costs in distributing the Funds' shares.

6.        BROKERAGE POLICY

          Although each Fund retains full control over its own investment
policies, under the terms of its Investment Advisory Agreement, the advisor is
directed to place the portfolio transactions of the Fund.  A report on the
placement of brokerage business is given to the directors or trustees of each
Fund every quarter, indicating the brokers with whom Fund portfolio business was
placed and the basis for such placement.  The brokerage commissions paid by the
Funds during the past three fiscal years were as follows:

</TABLE>

(1)  Covers period from March 29, 1996 (commencement of operations) through the
end of the Fund's first fiscal year on September 30, 1996.  The Fund paid more
brokerage commissions than anticipated during this period as a result of
portfolio transactions undertaken in response to volatile markets and the short
tax year for its initial period of operations.

(2)     The Berger Balanced Fund did not commence operations until September 30,
1997.  The Berger Select Fund and the Berger Mid Cap Growth Fund did not
commence operations until December 31, 1997.

(3)  The Fund's fiscal year end was changed from December 31 to September 30
during 1997.  Accordingly, the brokerage commissions shown for 1995 and 1996
were paid by the Fund during the fiscal years ended December 31, 1995, and
December 31, 1996, and the brokerage commissions shown for 1997 cover the period
January 1, 1997, through September 30, 1997.  

                                    -39-

(4) These are brokerage commissions paid by the Portfolio in which all the
Fund's investable assets are invested.  Commissions paid the Portfolio are borne
indirectly pro rata by the Fund and the other mutual funds invested in the
Portfolio.  Covers period November 7, 1996 (commencement of operations) through
the end of the Portfolio's first fiscal year on September 30, 1997.

          The Investment Advisory Agreement each Fund has with its advisor
authorizes and directs the advisor to place portfolio transactions for the Fund
only with brokers and dealers who render satisfactory service in the execution
of orders at the most favorable prices and at reasonable commission rates. 
However, each Agreement specifically authorizes the advisor to place such
transactions with a broker with whom it has negotiated a commission that is in
excess of the commission another broker or dealer would have charged for
effecting that transaction if the advisor determines in good faith that such
amount of commission was 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 the overall responsibilities of the advisor. 

          In accordance with this provision of the Agreement, portfolio
brokerage business of each Fund may be placed with brokers who provide useful 
research services to the advisor or, where applicable, the sub-advisor.  Such 
research services include computerized stock quotation and trading services, 
fundamental and technical analysis data and software, broker and other 
third-party equity research, computerized stock market and business news 
services, economic research and account performance data.  During the fiscal 
year ended September 30, 1997, of the brokerage commissions paid by the 
Funds, the following amounts were paid to brokers who agreed to provide to 
the Fund selected research services prepared by the broker or subscribed or 
paid for by the broker on behalf of the Fund: Berger New Generation Fund: 
$14,810; Berger Small Company Growth Fund: $24,864; Berger Small Cap Value 
Fund: $6,312; Berger 100 Fund: $750,126; Berger/BIAM International Fund: $0; 
and Berger Growth and Income Fund: $222,188.  Those services included a 
service used by the independent directors or trustees of the Funds in 
reviewing the Investment Advisory Agreements. 

          The research services received from brokers are often helpful to 
the advisor or sub-advisor in performing its investment advisory 
responsibilities to the Funds, but they are not essential, and the 
availability of such services from brokers does not reduce the responsibility 
of the advisor's or sub-advisor's advisory personnel to analyze and evaluate 
the securities in which the Funds invest.  The research services obtained as 
a result of the Funds' brokerage business also will be useful to the advisor 
or sub-advisor in making investment decisions for its other advisory 
accounts, and, conversely, information obtained by reason of placement of 
brokerage business of such other accounts may be used by the advisor or 
sub-advisor in rendering investment advice to the Funds.  Although such 
research services may be deemed to be of value to the advisor or sub-advisor, 
they are not expected to decrease the expenses that the advisor or 
sub-advisor would otherwise incur in performing its investment advisory 
services for the Funds nor will the advisory fees that are received by the 
advisor from the Funds be reduced as a result of the availability of such 
research services from brokers.

          The directors or trustees of each of the Funds have authorized 
portfolio transactions to be placed on an agency basis through DSTS, a 
wholly-owned broker-dealer subsidiary of DST.  When transactions are effected 
through DSTS, the commission received by DSTS is credited against, and 
thereby reduces, certain operating expenses that the Fund would otherwise be 
obligated to pay. No portion of the commission is retained by DSTS.  DSTS may 
be considered an affiliate of Berger Associates due to the ownership interest 
of KCSI in both DSTS and Berger Associates.  

          Included in the brokerage commissions paid by the Funds during the 
last three fiscal years, as stated in the preceding Brokerage Commissions 
table, are the following amounts paid to DSTS, which served to reduce each 
Fund's out-of-pocket expenses as follows:

certain procedures adopted by the trustees and subject to obtaining prompt
execution of orders at the most favorable net price.  Of the brokerage
commissions shown on the Brokerage Commissions table above, the following

</TABLE>

(1)     The Fund's fiscal year end was changed during 1997.  Covers the period
January 1, 1997, through February 14, 1997. 

          On February 14, 1997, new arrangements for the Berger Small Cap Value
Fund came into effect with shareholder approval and since that time, the
trustees have not authorized the Fund's brokerage to be placed with any broker
or dealer affiliated with the advisor or sub-advisor, except through DSTS under
the circumstances described above. 

          In selecting broker and dealers and in negotiating commissions, the 
Funds' advisors and sub-advisors consider a number of factors, including 
among others: the advisor's or sub-advisor's knowledge of currently available 
negotiated commission rates or prices of securities currently available and 
other current transaction costs; the nature of the security being traded; the 
size and type of the transaction; the nature and character of the markets for 
the security to be purchased or sold; the desired timing of the trade; the 
activity existing and expected in the market for the particular security; 
confidentiality; the quality of the execution, clearance and settlement 
services; financial stability of the broker or dealer; the existence of 
actual or apparent operational problems of any broker or dealer; and research 
products or services provided.  The directors or trustees of the Funds have 
also authorized sales of shares of the Fund by a broker-dealer and the 
recommendations of a broker-dealer to its customers that they purchase Fund 
shares to be considered as factors in the selection of broker-dealers to 
execute portfolio transactions for the Funds.  In addition, payments made by 
brokers to a Fund or to other persons on behalf of a Fund for services 
provided to the Fund for which it would otherwise be obligated to pay may 
also be considered.  In placing portfolio business with any such broker or 
dealer, the advisors and sub-advisors of the Funds will seek the best 
execution of each transaction.

          During the fiscal year ended September 30, 1997, the Berger New
Generation Fund acquired securities of Hambrecht & Quist Group, one of the
Fund's regular broker-dealers.  However, as of September 30, 1997, the Fund did
not own any of those securities.

7.        HOW TO PURCHASE SHARES IN THE FUNDS

          Minimum Initial Investment                              $2,000.00
          Minimum Subsequent Investment                             $ 50.00

          To purchase shares in any of the Funds, simply complete the
application form enclosed with the Prospectus.  Then mail it with a check
payable to "Berger Funds" to the Funds in care of DST Systems, Inc., the Funds'
sub-transfer agent, as follows:

          Berger Funds
          c/o DST Systems, Inc.
          P.O. Box 419958
          Kansas City, MO  64141

                                    -42-
<PAGE>

          If a shareholder is adding to an existing account, shares may also be
purchased by placing an order by telephone call to the Funds at 1-800-551-5849
or via on-line access, and remitting payment to DST Systems, Inc.  Payment for
shares ordered on-line must be made by electronic funds transfer.  In order to
make sure that payment for telephone purchases is received on time, shareholders
are encouraged to remit payment by electronic funds transfer.  Shareholders may
also remit payment for telephone purchases by wire or by overnight delivery.

          In addition, Fund shares may be purchased through certain 
broker-dealers that have established mutual fund programs and certain other 
organizations connected with pension and retirement plans.  These 
broker-dealers and other organizations may charge investors a transaction or 
other fee for their services, may require different minimum initial and 
subsequent investments than the Funds and may impose other charges or 
restrictions different from those applicable to shareholders who invest in 
the Funds directly.  Fees charged by these organizations will have the effect 
of reducing a shareholder's total return on an investment in Fund shares.  No 
such charge will apply to an investor who purchases Fund shares directly from 
a Fund as described above.  

          Procedures for purchasing, selling (redeeming) and exchanging Fund
shares by telephone and on-line are described in the Prospectus.  The Funds may
terminate or modify those procedures and related requirements at any time,
although shareholders of the Funds will be given notice of any termination or
material modification.   Berger Associates may, at its own risk, waive certain
of those procedures and related requirements.

          CLOSING OF BERGER SMALL COMPANY GROWTH FUND TO NEW INVESTORS.  The
Berger Small Company Growth Fund was closed to new investors effective November
17, 1997.  Due to the Fund's current size relative to the range of suitable
investments available to the Fund, the Trustees determined that it is in the
best interests of the Fund and its shareholders to restrict the Fund's growth at
this time.  Currently, you may purchase shares in the Fund if:

       - You are an existing shareholder in the Fund as of the closing date 
         and you:
          - Add to your account through the purchase of additional Fund shares.
          - Add to your account through the reinvestment of dividends and cash
            distributions from any shares owned in the Fund.
       - You purchase shares as a participant in a 401(k) or other employee 
         benefit plan that the Fund has approved to include shares of the Fund
         as an investment alternative.
       - You purchase shares as an employee of an eligible employer that 
         established an omnibus 403(b) account with the Fund on or before 
         November 17, 1997.

          If you redeem or exchange all your remaining Fund shares, you will not
be permitted to buy back into the Fund so long as the Fund remains closed to new
investors.  If your Fund account drops below the applicable minimum balance, all
your remaining shares will be subject to involuntary redemption by the Fund as
described in the Prospectus. 

          The Fund may resume sales to new investors at some future date if the
Trustees of the Fund determine that it is in the best interests of the Fund and
its shareholders.  All of the other Berger Funds continue to be available to new
investors.

8.        HOW THE NET ASSET VALUE IS DETERMINED

          The net asset value of each Fund is determined once daily, at the
close of the regular trading session of the New York Stock Exchange (the
"Exchange") (normally 4:00 p.m., New York time, Monday through Friday) each day
that the Exchange is open.  The Exchange is closed and the net asset value of
the Funds is not determined on weekends and on New Year's Day, Martin Luther
King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day and 

                                    -43-
<PAGE>

Christmas Day each year.  The per share net asset value of each Fund is 
determined by dividing the total value of its securities and other assets, 
less liabilities, by the total number of shares outstanding.   

          Net asset value for the Berger Small Cap Value Fund is calculated by
class, and since the Investor Shares and each other class of the Fund has its
own expenses, the per share net asset value of the Fund will vary by class.  

          Since the Berger/BIAM International Fund invests all of its investable
assets in the Berger/BIAM International Portfolio, the value of the Fund's
investable assets will be equal to the value of its beneficial interest in the
Portfolio.  The value of securities held in the Portfolio are determined as
described below for the Funds.

          In determining net asset value for each of the Funds, securities
listed or traded primarily on national exchanges, The Nasdaq Stock Market and
foreign exchanges are valued at the last sale price on such markets, or, if such
a price is lacking for the trading period immediately preceding the time of
determination, such securities are valued at the mean of their current bid and
asked prices.  Securities that are traded in the over-the-counter market are
valued at the mean between their current bid and asked prices.  The market value
of individual securities held by each Fund will be determined by using prices
provided by pricing services which provide market prices to other mutual funds
or, as needed, by obtaining market quotations from independent broker/dealers. 
Short-term money market securities maturing within 60 days are valued on the
amortized cost basis, which approximates market value.  All assets and
liabilities initially expressed in terms of non-U.S. dollar currencies are
translated into U.S. dollars at the prevailing market rates as quoted by one or
more banks or dealers shortly before the close of the Exchange.  Securities and
assets for which quotations are not readily available or are not representative
of market value may be valued at their fair value determined in good faith
pursuant to consistently applied procedures established by the directors or
trustees.

          Generally, trading in foreign securities markets is substantially
completed each day at various times prior to the close of the Exchange.  The
values of foreign securities used in computing the net asset value of the shares
of a Fund are determined as of the earlier of such market close or the closing
time of the Exchange.  Occasionally, events affecting the value of such
securities may occur between the times at which they are determined and the
close of the Exchange, or when the foreign market on which such securities trade
is closed but the Exchange is open, which will not be reflected in the
computation of net asset value.  If during such periods, events occur which
materially affect the value of such securities, the securities may be valued at
their fair value as determined in good faith pursuant to consistently applied
procedures established by the directors or trustees.

          A Fund's securities may be listed primarily on foreign exchanges or
over-the-counter dealer markets which may trade on days when the Exchange is
closed (such as a customary U.S. holiday) and on which the Fund's net asset
value is not calculated.  As a result, the net asset value of a Fund may be
significantly affected by such trading on days when shareholders cannot purchase
or redeem shares of the Fund. 

9.        INCOME DIVIDENDS, CAPITAL GAINS
          DISTRIBUTIONS AND TAX TREATMENT

          This discussion summarizes certain U.S. federal income tax issues
relating to the Funds.  As a summary, it is not an exhaustive discussion of all
possible tax ramifications.  Accordingly, shareholders are urged to consult with
their tax advisors with respect to their particular tax consequences.

          TAX STATUS OF THE FUNDS.  If a Fund meets certain investment and
distribution requirements, it will be treated as a "regulated investment
company" (a "RIC") under the Internal Revenue Code and will not be subject to
federal income tax on earnings that it distributes in a timely

                                    -44-

<PAGE>

manner to shareholders.  It also may be subject to an excise tax on 
undistributed income if it does not meet certain timing requirements for 
distributions.  Each of the Funds intends to qualify as a RIC annually and to 
make timely distributions in order to avoid income and excise tax liabilities.

          TAX ON FUND DISTRIBUTIONS.  With certain exceptions provided by law,
the Funds will report annually to the Internal Revenue Service and to each
shareholder information about the tax treatment of the shareholder's
distributions.  Dividends paid by a Fund, whether received in cash or reinvested
in additional Fund shares, will be treated as ordinary income to the
shareholders.  Distributions of net capital gain, whether received in cash or
reinvested in Fund shares, will be taxable to the shareholders, but the rate of
tax will vary depending upon the Fund's holding periods in the assets whose sale
resulted in the capital gain.  Dividends and distributions that are declared in
October, November or December but not distributed until the following January
will be considered to be received by the shareholders on December 31.

          In general, net capital gains from assets held by a Fund for more than
18 months will be subject to a maximum tax rate of 20%; net capital gains from
assets held for more than one year but no more than 18 months will be subject to
a maximum tax rate of 28%; and net capital gains from assets held for one year
or less will be taxed as ordinary income.   Distributions will be subject to
these capital gains rates, regardless of how long a shareholder has held Fund
shares. 

          If a Fund's distributions for a taxable year exceeds its tax earnings
and profits available for distribution, all or a portion of its distributions
may be treated as a return of capital or as capital gains.  To the extent a
distribution is treated as a return of capital, a shareholder's basis in his or
her Fund shares will be reduced by that amount.

          If a shareholder has elected to receive dividends and/or capital gain
distributions in cash and the U.S. Postal Service is unable to deliver checks to
the shareholder's address of record, or if a shareholder's checks remain
uncashed for six months, the Funds reserve the right to reinvest the amount
distributed in additional Fund shares at the then-current NAV and to convert the
shareholder's distribution option from receiving cash to having all dividend and
other distributions reinvested in additional shares.  In addition, no interest
will accrue on amounts represented by uncashed distribution or redemption
checks.

          TAX ON REDEMPTIONS OF FUND SHARES.  Shareholders may be subject to tax
on the disposition of their Fund shares.  In general, such dispositions may give
rise to a capital gain or loss, the treatment of which will depend on the
shareholder's holding period in the Fund shares.  Tax laws may prevent the
deduction of a loss on the sale of Fund shares if the shareholder reinvests in
the Fund shortly before or after the sale giving rise to the loss.  Any loss on
the redemption or other sale or exchange of Fund shares held for six months or
less will be treated as a long-term capital loss to the extent of any long-term
capital gain distribution received on the shares.

          INCOME FROM FOREIGN SOURCES.  Dividends and interest received by the
Funds on foreign securities may give rise to withholding and other taxes imposed
by foreign countries, although these taxes may be reduced by applicable tax
treaties.  Foreign taxes will generally be treated as expenses of the Funds,
unless a Fund has more than 50% of its assets invested in foreign corporate
securities at the end of the Fund's taxable year.  In that case, shareholders of
the Fund may be able to deduct (as an itemized deduction) or claim a foreign tax
credit for their share of foreign taxes, subject to limitations prescribed in
the tax law.  

          If a Fund invests in a foreign corporation that is a passive foreign
investment company (a "PFIC"), special rules apply that may affect the tax
treatment of gains from the sale of the stock and may cause a Fund to incur IRS
interest charges.  The Funds may make appropriate tax elections to mitigate the
tax effects of owning PFIC stock, including elections to "mark-to-market" PFIC
shares each year.  The mark-to-market regime may increase or decrease a Fund's
distributable income.

                                    -45-
<PAGE>

          INCOME FROM CERTAIN TRANSACTIONS.  Some or all of the Funds'
investments may include transactions that are subject to special tax rules. 
Transactions involving foreign currencies may give rise to gain or loss that
could affect a Fund's ability to make ordinary dividend distributions. 
Investment in certain financial instruments, such as options, futures contracts
and forward contracts, may require annual recognition of unrealized gains and
losses.  Transactions that are treated as "straddles" may affect the character
and/or timing of other gains and losses of the Fund.  If a Fund enters into a
transaction (such as a "short sale against the box") that reduces the risk of
loss on an appreciated financial position that it already holds, the entry into
the transaction may constitute a constructive sale and require immediate
recognition of gain.

          BACKUP WITHHOLDING.  In general, if a shareholder is subject to backup
withholding, a Fund will be required to withhold federal income tax at a rate of
31% from distributions to that shareholder.  These payments are creditable
against the shareholder's federal income tax liability.

          FOREIGN SHAREHOLDERS.  Foreign shareholders of a Fund generally will
be subject to a 30% U.S. withholding tax on dividends paid by a Fund from
ordinary income and short-term capital gain, although the rate may be reduced by
a tax treaty.  If a foreign shareholder dies while owning Fund shares, those
shares may be subject to U.S. estate taxes.

          TAX STATUS OF THE BERGER/BIAM INTERNATIONAL PORTFOLIO.  The
Berger/BIAM International Portfolio, in which the Berger/BIAM International Fund
invests all its investable assets, has in previous years been classified as a
partnership for U.S. federal income tax purposes, and it intends to retain that
classification.  The Berger/BIAM International Fund is treated  for various
federal tax purposes as owning a proportionate share of the Portfolio's assets
and will be taxable on its proportionate share of the Portfolio's income, gain
and loss.

10.       SUSPENSION OF REDEMPTION RIGHTS

          The right of redemption may be suspended for any period during which
the New York Stock Exchange is closed or the Securities and Exchange Commission
determines that trading on the Exchange is restricted, or when there is an
emergency as determined by the Securities and Exchange Commission as a result of
which it is not reasonably practicable for a Fund to dispose of securities owned
by it or to determine the value of its net assets, or for such other period as
the Securities and Exchange Commission may by order permit for the protection of
shareholders of a Fund.

          Each Fund intends to redeem its shares only for cash, although it
retains the right to redeem its shares in-kind under unusual circumstances, in
order to protect the interests of the remaining shareholders, by the delivery of
securities selected from its assets at its discretion.  Each Fund is, however,
governed by Rule 18f-1 under the Investment Company Act of 1940 pursuant to
which the Fund is obligated to redeem shares solely in cash up to the lesser of
$250,000 or 1% of the net assets of the Fund during any 90-day period for any
one shareholder.  For purposes of this threshold, each underlying account holder
whose shares are held of record in certain omnibus accounts is treated as one
shareholder.  Should redemptions by any shareholder during any 90-day period
exceed such limitation, the Fund will have the option of redeeming the excess in
cash or in-kind.  If shares are redeemed in-kind, the redeeming shareholder
generally will incur brokerage costs in converting the assets to cash.  The
method of valuing securities used to make redemption in-kind will be the same as
the method of valuing portfolio securities described under Section 8.  

11.       TAX-SHELTERED RETIREMENT PLANS

          The Funds offer several tax-qualified retirement plans for
individuals, businesses and non-profit organizations, including a Profit-Sharing
Plan, a Money Purchase Pension Plan, an Individual Retirement Account (IRA), a
Roth IRA and a 403(b) Custodial Account for adoption by employers and
individuals who wish to participate in such Plans.  For information on other
types of retirement plans


                                     -46-

<PAGE>

offered by the Funds, please call 1-800-333-1001 or
write to the Funds c/o Berger Associates, P.O. Box 5005, Denver, CO 80217.  

PROFIT-SHARING AND MONEY PURCHASE PENSION PLANS

          Employers, self-employed individuals and partnerships may make
tax-deductible contributions to the tax-qualified retirement plans offered by
the Funds.  All income and capital gains accumulated in the Plans are tax free
until withdrawn.  The amounts that are deductible depend upon the type of Plan
or Plans adopted.

          If you, as an employer, self-employed person or partnership, adopt the
Profit-Sharing Plan, you may vary the amount of your contributions from year to
year and may elect to make no contribution at all for some years.  If you adopt
the Money Purchase Pension Plan, you must commit yourself to make a contribution
each year according to a formula in the Plan that is based upon your employees'
compensation or your earned income.  By adopting both the Profit-Sharing and the
Money Purchase Pension Plan, you can increase the amount of contributions that
you may deduct in any one year.

          If you wish to purchase shares of any Fund in conjunction with one 
or both of these tax-qualified plans, you may use an Internal Revenue Service 
approved prototype Trust Agreement and Retirement Plan available from the 
Funds. IFTC serves as trustee of the Plan, for which it charges an annual 
trustee's fee for each Fund or Cash Account Trust Money Portfolio (discussed 
below) in which the participant's account is invested.  Contributions under 
the Plans are invested exclusively in shares of the Funds or the Cash Account 
Trust Money Market Portfolios, which are then held by the trustee under the 
terms of the Plans to create a retirement fund in accordance with the tax 
code.

          Distributions from the Profit-Sharing and Money Purchase Pension Plans
generally may not be made without penalty until the participant reaches
age 591/2 and must begin no later than April 1 of the calendar year following
the year in which the participant attains age 701/2.  A participant who is not a
5% owner of the employer may postpone such distributions to April 1 of the
calendar year following the year of retirement.  This exception does not apply
to distributions from an individual retirement account (IRA).  Except for
required distributions after age 701/2, periodic distributions over more than 10
years and the distribution of any after-tax contributions, distributions are
subject to 20% Federal income tax withholding unless those distributions are
rolled directly to another qualified plan or an IRA.  Participants may not be
able to receive distributions immediately upon request because of certain
requirements under federal tax law.  Since distributions which do not satisfy
these requirements can result in adverse tax consequences, consultation with an
attorney or tax advisor regarding the Plans is recommended.  You should also
consult with your tax advisor regarding state tax law implications of
participation in the Plans.

          In order to receive the necessary materials to create a 
Profit-Sharing or Money Purchase Pension Plan, please write to the Funds, c/o 
Berger Associates, Inc., P.O. Box 5005, Denver, Colorado 80217, or call 
1-800-333-1001. Trustees for 401(k) or other existing plans interested in 
utilizing Fund shares as an investment or investment alternative in their 
plans should contact the Funds at 1-800-333-1001.

INDIVIDUAL RETIREMENT ACCOUNT (IRA)

          If you are an individual with compensation or earned income, whether
or not you are actively participating in an existing qualified retirement plan,
you can provide for your own retirement by adopting an IRA.  Under an IRA, you
can contribute each year up to the lesser of 100% of your compensation or
$2,000.  If you are married and you file a joint return, you and your spouse
together may make contributions totaling up to $4,000 to two IRAs (with no more
than $2,000 being contributed to either account) if your joint income is $4,000
or more, even if one spouse has no earned income.  If neither you nor your
spouse are active participants in an existing qualified retirement plan, or if
your


                                     -47-

<PAGE>

income does not exceed certain amounts, the amounts contributed to your IRA 
can be deducted for Federal income tax purposes whether or not your 
deductions are itemized.  If you or your spouse are covered by an existing 
qualified retirement plan, the deductibility of your IRA contributions will 
be phased out for federal income tax purposes if your income exceeds 
specified amounts, although the income level at which your IRA contributions 
will no longer be deductible is higher if only your spouse (but not you) is 
an active participant. However, whether your contributions are deductible or 
not, the income and capital gains accumulated in your IRA are not taxed until 
the account is distributed.

          If you wish to create an IRA to invest in shares of any Fund, you may
use the Fund's IRA custodial agreement form which is an adaptation of the form
provided by the Internal Revenue Service.  Under the IRA custodial agreement,
IFTC will serve as custodian, for which it will charge an annual custodian fee
for each Fund or Cash Account Trust Money Market Portfolio in which the IRA is
invested.

          Distributions from an IRA generally may not be made without penalty
until you reach age 591/2 and must begin no later than April 1 of the calendar
year following the year in which you attain age 701/2.  Since distributions
which do not satisfy these requirements can result in adverse tax consequences,
consultation with an attorney or tax advisor is recommended.

          In order to receive the necessary materials to create an IRA account,
please write to the Funds, c/o Berger Associates, Inc., P.O. Box 5005, Denver,
Colorado 80217, or call 1-800-333-1001.

ROTH IRA

          If you are an individual with compensation or earned income, you may
contribute up to the lesser of $2,000 or 100% of your compensation to a Roth
IRA, as long as your income does not exceed a specified income level ($95,000
for single individuals, $150,000 for married individuals filing jointly).  A
Roth IRA is similar in many respects to a traditional IRA, as described above. 
However, the maximum amount you may contribute to a Roth IRA is phased out
between that income level and a maximum income amount ($110,000 and $160,000,
respectively), and you may not make any contribution at all to a Roth IRA if
your income exceeds the maximum income amount.  Also, you can make contributions
to a Roth IRA even after you reach age 70-1/2, and you are not required to take
distributions from a Roth IRA prior to your death.

          Contributions to a Roth IRA are not deductible for federal income tax
purposes.  However, the income and capital gains accumulated in a Roth IRA are
not taxed while held in the IRA, and distributions can be taken tax-free if the
Roth IRA has been established for a minimum of five years and the distribution
is after age 59-1/2, for a first time home purchase, or upon death or
disability.

          An individual with an income of less than $100,000 who is not married
filing separately can roll his or her existing IRA into a Roth IRA.  However,
the individual must pay taxes on the taxable amount of the traditional IRA
account balance.  Individuals who complete the rollover in 1998 will be
permitted to spread the tax liability over a four-year period.  After 1996, all
taxes on such a rollover will be due in the year in which the rollover is made.

403(b) CUSTODIAL ACCOUNTS

          If you are employed by a public school system or certain federally
tax-exempt private schools, colleges, universities, hospitals, religious and
charitable or other nonprofit organizations, you may establish a 403(b)
Custodial Account.  Your employer must participate in the establishment of the
account.

          If your employer participates, it will automatically deduct the amount
you designate from your gross salary and contribute it to your 403(b) Custodial
Account.  The amount which you may contribute annually under a salary reduction
agreement is generally the lesser of $9,500 or your exclusion


                                     -48-

<PAGE>

allowance, which is based upon a specified formula, and other Internal 
Revenue Code limits apply. There is a $50 minimum investment in the 403(b) 
Custodial Account. Contributions made to the account reduce the amount of 
your current income subject to Federal income tax.  Federal income tax is not 
paid on your contribution until you begin making withdrawals.  In addition, 
all income and capital gains accumulated in the account are tax-free until 
withdrawn.

          Withdrawals from your 403(b) Custodial Agreement may begin as soon as
you reach age 59-1/2 and must begin no later than April 1 of the year following
the later of the calendar year in which you attain age 701/2 or the calendar
year in which you retire.  Except for required distributions after age 701/2 and
periodic distributions over more than 10 years, distributions are subject to 20%
Federal income tax withholding unless those distributions are rolled directly to
another 403(b) account or annuity or an individual retirement account (IRA). 
You may not be able to receive distributions immediately upon request because of
certain notice requirements under federal tax law.  Since distributions which do
not satisfy these requirements can result in adverse tax consequences,
consultation with an attorney or tax advisor regarding the 403(b) Custodial
Account is recommended.  You should also consult with your tax advisor about
state taxation of your account.

          Individuals who wish to purchase shares of a Fund in conjunction with
a 403(b) Custodial Account may use a Custodian Account Agreement and related
forms available from the Funds.  IFTC serves as custodian of the 403(b)
Custodial Account, for which it charges an annual custodian fee for each Fund or
Cash Account Trust Money Market Portfolio in which the participant's account is
invested.

          In order to receive the necessary materials to create a 403(b)
Custodial Account, please write to the Funds, c/o Berger Associates, Inc., P.O.
Box 5005, Denver, Colorado 80217, or call 1-800-333-1001.

12.       EXCHANGE PRIVILEGE AND SYSTEMATIC WITHDRAWAL PLAN

          A shareholder who owns shares of any of the Funds worth at least
$5,000 at the current net asset value may establish a Systematic Withdrawal
account from which a fixed sum will be paid to the shareholder at regular
intervals by the Fund in which the shareholder is invested.

          To establish a Systematic Withdrawal account, the shareholder deposits
Fund shares with the Fund and appoints the Fund as agent to redeem shares in the
shareholder's account in order to make monthly, quarterly, semi-annual or annual
withdrawal payments to the shareholder of a fixed amount.  The minimum
withdrawal payment is $50.00.  These payments generally will be made on the 25th
day of the month.

          Withdrawal payments are not yield or income on the shareholder's
investment, since portions of each payment will normally consist of a return of
the shareholder's investment.  Depending on the size of the disbursements
requested and the fluctuation in value of the Fund's portfolio, redemptions for
the purpose of making such disbursements may reduce or even exhaust the
shareholder's account.

          The shareholder may vary the amount or frequency of withdrawal
payments, temporarily discontinue them, or change the designated payee or
payee's address, by notifying the Fund.  The shareholder may, of course, make
additional deposits of Fund shares in the shareholder's account at any time.

          Since redemption of shares to make withdrawal payments is a taxable
event, each investor should consult a tax advisor concerning proper tax
treatment of the redemption.

          Any shareholder may exchange any or all of the shareholder's shares in
any of the Funds for shares of any of the other available Berger Funds or for
shares of the Money Market Portfolio, the


                                     -49-

<PAGE>

Government Securities Portfolio or the Tax-Exempt Portfolio of the Berger 
Cash Account Trust ("Berger CAT Portfolios"), separately managed, 
unaffiliated money market funds, without charge, after receiving a current 
prospectus of the other Fund or Berger CAT Portfolio.  The exchange privilege 
with the Berger CAT Portfolios does not constitute an offering or 
recommendation of the shares of any such Berger CAT Portfolio by any of the 
Funds or Berger Associates.  Berger Associates is compensated for 
administrative services it performs with respect to the Berger CAT 
Portfolios.

          Exchanges into or out of the Funds are made at the net asset value per
share next determined after the exchange request is received.  Each exchange
represents the sale of shares from one Fund and the purchase of shares in
another, which may produce a gain or loss for income tax purposes.  An exchange
of shares may be made by written request directed to DST Systems, Inc., via
on-line access, or simply by telephoning the Berger Funds at 1-800-551-5849. 
This privilege is revocable by any of the Funds, and is not available in any
state in which the shares of the Fund or Berger CAT Portfolio being acquired in
the exchange are not eligible for sale.  Shareholders automatically have
telephone and on-line privileges to authorize exchanges unless they specifically
decline this service in the account application or in writing.

13.       PERFORMANCE INFORMATION

          From time to time in advertisements, the Funds may discuss their
performance ratings as published by recognized mutual fund statistical services,
such as Lipper Analytical Services, Inc., CDA Investment Technologies, Inc., or
Morningstar, Inc., or Value Line Investment Survey or by publications of general
interest such as THE WALL STREET JOURNAL, INVESTOR'S BUSINESS DAILY, MONEY,
BARRON'S, FINANCIAL WORLD or KIPLINGER'S PERSONAL FINANCE MAGAZINE.  In
addition, the Funds may compare their performance to that of recognized
broad-based securities market indices, including the Standard & Poor's 500 Stock
Index, the Dow Jones Industrial Average, the Russell 2000 Stock Index, the
Standard & Poor's 400 Mid-Cap Index, the Standard & Poor's 600 Small Cap Index,
Morgan Stanley Capital International EAFE (Europe, Australasia, Far East) Index,
the Dow Jones World Index, the Standard & Poor's/BARRA Value Index, the Nasdaq
Composite Index or the Lehman Brothers Intermediate Term Government/Corporate
Bond Index, or more narrowly-based or blended indices which reflect the market
sectors in which that Fund invests.

          The total return of each Fund is calculated for any specified period
of time by assuming the purchase of shares of the Fund at the net asset value at
the beginning of the period.  Each dividend or other distribution paid by the
Fund is assumed to have been reinvested at the net asset value on the
reinvestment date.  The total number of shares then owned as a result of this
process is valued at the net asset value at the end of the period.  The
percentage increase is determined by subtracting the initial value of the
investment from the ending value and dividing the remainder by the initial
value.

          Each Fund's total return reflects the Fund's performance over a stated
period of time.  An average annual total return reflects the hypothetical
annually compounded return that would have produced the same total return if the
Fund's performance had been constant over the entire period.  Total return
figures are based on the overall change in value of a hypothetical investment in
each Fund.  Because average annual total returns for more than one year tend to
smooth out variations in a Fund's return, investors should recognize that such
figures are not the same as actual year-by-year results.

          All performance figures for the Funds are based upon historical
results and do not assure future performance.  The investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost.

          Quotations of average annual total return for the Funds will be
expressed in terms of the average annual compounded rate of return of a
hypothetical investment in the Fund over periods of 1, 5 and 10 years, or for
the life of the Fund, if shorter.  These are the rates of return that would
equate the initial amount invested to the ending redeemable value.  These rates
of return are calculated pursuant


                                     -50-

<PAGE>

to the following formula:  P(1 + T)(n) = ERV (where P = a hypothetical 
initial payment of $1,000, T = the average annual total return, n = the 
number of years and ERV = the ending redeemable value of a hypothetical 
$1,000 payment made at the beginning of the period).  All total return 
figures reflect the deduction of a proportional share of Fund expenses on an 
annual basis, and assume that all dividends and distributions are reinvested 
when paid.

PREDECESSOR PERFORMANCE QUOTATIONS

          BERGER/BIAM INTERNATIONAL FUND.  The Berger/BIAM International
Portfolio (in which all the investable assets of the Berger/BIAM International
Fund are invested) commenced operations upon the transfer to the Portfolio of
assets held in a pooled trust (the "Pool") maintained by Citizens Bank New
Hampshire, for which BIAM had provided day-to-day portfolio management as
sub-advisor since the inception of the Pool.  BIAM's bank holding company parent
indirectly owns a 23.5% interest in the parent of Citizens Bank New Hampshire. 
The investment objective, policies, limitations, guidelines and strategies of
the Pool were materially equivalent to those of the Berger/BIAM International
Fund and the Portfolio.  Assets from the Pool were transferred on October 11,
1996, to a separate "feeder" fund investing in the Portfolio which, in turn,
transferred those assets to the Portfolio in exchange for an interest in the
Portfolio.  As a result of this transaction, the investment holdings in the
Portfolio were the same as the investment holdings in the portfolio of the Pool
immediately prior to the transfer, except for the seed capital provided by
Berger Associates.

          The Pool was not a registered investment company since it was exempt
from registration under the Investment Company Act of 1940 (the "1940 Act"). 
Since, in a practical sense, the Pool constitutes the "predecessor" of the
Portfolio, the Fund calculates its performance for periods commencing prior to
the transfer of the Pool's assets to the Portfolio by including the Pool's total
return, adjusted at that time to reflect any increase in fees and expenses
applicable in operating the Fund, including the Fund's pro rata share of the
aggregate annual operating expenses, net of fee waivers, of the Portfolio. 
Those fees and expenses included 12b-1 fees.

          Performance data quoted for the Berger/BIAM International Fund for
periods prior to October 1996 include the performance of the Pool and include
periods before the Fund's and the Portfolio's registration statements became
effective.  As noted above, the Pool was not registered under the 1940 Act and
thus was not subject to certain investment restrictions that are imposed on the
Fund and the Portfolio by the 1940 Act.  If the Pool had been registered under
the 1940 Act, the Pool's performance might have been adversely affected.

          BERGER SMALL CAP VALUE FUND.  Shares of the Berger Small Cap Value
Fund had no class designations until February 14, 1997, when all of the
then-existing shares were designated as Institutional Shares and the Fund
commenced offering the Investor Shares covered in this Statement of Additional
Information.  Performance data for the Investor Shares include periods prior to
the adoption of class designations on February 14, 1997, and therefore do not
reflect the 0.25% per year 12b-1 fee applicable to the Investor Shares.  Total
return of the Investor Shares and other classes of shares of the Fund will be
calculated separately.  Because each class of shares is subject to different
expenses, the performance of each class for the same period will differ.  

AVERAGE ANNUAL TOTAL RETURNS

          The average annual total return for each of the Funds in existence for
various periods ending September 30, 1997, are shown on the following table:

14.       ADDITIONAL INFORMATION

FUND ORGANIZATION

          BERGER 100 FUND AND BERGER GROWTH AND INCOME FUND.  The Berger 100
Fund and Berger Growth and Income Fund are separate corporations which were
incorporated under the laws of the State of Maryland on March 10, 1966, as "The
One Hundred Fund, Inc." and "The One Hundred and One Fund, Inc.", respectively. 
The names "Berger One Hundred Fund-Registered Trademark-", "Berger
100 Fund-Registered Trademark-", "Berger One Hundred and One Fund-Registered
Trademark-" and "Berger 101 Fund-Registered Trademark-" were adopted by the
respective Funds as service marks and trade names in November 1989.  In 1990,
the shareholders of the Berger Growth and Income Fund approved changing its
formal corporate name to "Berger One Hundred and One Fund, Inc." and the Fund
began doing business under the trade name "Berger Growth and Income Fund, Inc."
in January 1996.

          Each of the Berger 100 Fund and the Berger Growth and Income Fund has
only one class of securities, its Capital Stock, with a par value of one cent
per share, of which 200,000,000 shares are authorized for issue by the
Berger 100 Fund and 100,000,000 shares are authorized for issue by the
Berger Growth and Income Fund.  Shares of the Funds are fully paid and
nonassessable when issued.  All shares issued by a Fund participate equally in
dividends and other distributions by the Fund, and in the residual assets of the
Fund in the event of its liquidation.

          BERGER SMALL COMPANY GROWTH FUND, BERGER NEW GENERATION FUND, BERGER
BALANCED FUND, BERGER SELECT FUND AND BERGER MID CAP GROWTH FUND.  The
Berger Small Company Growth Fund is a separate series established on August 23,
1993, under the Berger Investment Portfolio Trust, a Delaware business trust
established under the Delaware Business Trust Act.  The name "Berger Small
Company Growth Fund-Registered Trademark-" was registered as a service mark in
September 1995.  The Berger New Generation Fund was the second series created
under the Berger Investment Portfolio Trust, established on December 21, 1995. 
The Berger Balanced Fund was the third series created under the Berger
Investment Portfolio Trust, established on August 22, 1997.  The Berger Select
Fund and the Berger Mid Cap Growth Fund were the fourth and fifth series created
under the Trust, established on November 13, 1997.  The Trust is authorized to
issue an unlimited number of shares of beneficial interest in series or
portfolios.  Currently, the Berger Small Company Growth Fund, the Berger New
Generation Fund, the Berger Balanced Fund, the Berger Select Fund and the Berger
Mid Cap Growth Fund are the only series established under the Trust, although
others may be added in the future.  The Trust is also authorized to establish
multiple classes of shares representing differing interests in an existing or
new series.  Shares of the Funds are fully paid and nonassessable when issued. 
Each share has a par value of $.01.  All shares issued by each Fund participate
equally in dividends and other distributions by the Fund, and in the residual
assets of the Fund in the event of its liquidation.

          BERGER/BIAM INTERNATIONAL FUND.  The Berger/BIAM Worldwide Funds Trust
is a Delaware business trust organized on May 31, 1996.  The Berger/BIAM
International Fund was established on May 31, 1996, as a series of the Trust. 
The Trust is authorized to issue an unlimited number of shares of beneficial
interest in series or portfolios.  Currently, the series comprising the Fund is
one of three series established under the Trust, although others may be added in
the future.  The Trust is also authorized to establish multiple classes of
shares representing differing interests in an existing or new series.  Shares of
the Fund are fully paid and non-assessable when issued.  Each share has a par
value of $.01.  All shares issued by the Fund participate equally in dividends
and other distributions by the Fund, and in the residual assets of the Fund in
the event of its liquidation.

          Berger/BIAM Worldwide Portfolios Trust is also a Delaware business
trust organized on May 31, 1996.  The Berger/BIAM International Portfolio (in
which all the investable assets of the Berger/BIAM International Fund are
invested) was established on May 31, 1996, as a series of that Trust.  Like the
Berger/BIAM International Fund, the Portfolio is a diversified, open-end
management investment company.  The Portfolio commenced operations upon the
transfer to the Portfolio of assets held in a


                                     -53-

<PAGE>

pooled trust.  See "Performance Information -- Predecessor Performance Data 
- -- Berger/BIAM International Fund" above for additional information on the 
asset transfer.  The Berger/BIAM Worldwide Portfolios Trust is authorized to 
sell unlimited interests in series or portfolios.  Interests may be divided 
into classes.  Currently, the series comprising the Portfolio is the only 
series established under that Trust, although others may be added in the 
future. 

          Each investor in the Portfolio, including the Fund, is entitled to 
a vote in proportion to the amount of its investment in the Portfolio.  
Whenever the Fund is requested to vote as an investor in the Portfolio on 
matters pertaining to the Portfolio (other than a vote by the Fund to 
continue the operation of the Portfolio upon the withdrawal of another 
investor in the Portfolio), the Fund will hold a meeting of its shareholders 
and will cast all of its votes as an investor in the Portfolio in the same 
proportion as directed by the votes of the Fund's shareholders.  Fund 
shareholders who do not vote will not affect the votes cast by the Fund at 
the meeting of the Portfolio investors. The percentage of the votes 
representing the Fund's shareholders who do not vote will be voted by the 
Fund in the same proportion as the Fund's shareholders who do, in fact, vote. 

          BERGER SMALL CAP VALUE FUND.  The Berger Small Cap Value Fund was
originally organized in November 1984 as a Delaware corporation.  In May 1990,
the Fund was reorganized from a Delaware corporation into a Massachusetts
business trust known as The Omni Investment Fund.  Pursuant to the Fund's
reorganization, the Fund as a series of the Trust assumed all of the assets and
liabilities of the Fund as a Delaware corporation, and Fund shareholders
received shares of the Massachusetts business trust equal both in number and net
asset value to their shares of the Delaware corporation.  All references in this
Statement of Additional Information to the Fund and all financial and other
information about the Fund prior to such reorganization are to the Fund as a
Delaware corporation.  All references after such reorganization are to the Fund
as a series of the Trust.  On February 14, 1997, the name of the Trust was
changed to Berger Omni Investment Trust and the name of the Fund was changed to
the Berger Small Cap Value Fund.

          The Trust is authorized to issue an indefinite number of shares of
beneficial interest having a par value of $0.01 per share, which may be issued
in any number of series.  Currently, the Fund is the only series established
under the Trust, although others may be added in the future.  The shares of each
series of the Trust are permitted to be divided into classes.  Currently, the
Fund issues two classes of shares, although others may be added in the future.

          Under the Fund's Declaration of Trust, each trustee will continue in
office until the termination of the Trust or his or her earlier death,
resignation, incapacity, retirement or removal.  Vacancies will be filled by a
majority vote of the remaining trustees, subject to the provisions of the
Investment Company Act of 1940.  Shareholders have the power to vote for the
election and removal of trustees, to terminate or reorganize the Trust, to amend
the Declaration of Trust, and on any other matters on which a shareholder vote
is required by the Investment Company Act of 1940, the Declaration of Trust, the
Trust's bylaws or the trustees.  

          DELAWARE BUSINESS TRUST INFORMATION.  Under Delaware law, shareholders
of the Funds organized as series of Delaware Business Trusts will enjoy the same
limitations on personal liability as extended to stockholders of a Delaware
corporation.  Further, the Trust Instruments of those Trusts provides that no
shareholder shall be personally liable for the debts, liabilities, obligations
and expenses incurred by, contracted for or otherwise existing with respect to,
the Trusts or any particular series (fund) of the Trusts.  However, the
principles of law governing the limitations of liability of beneficiaries of a
business trust have not been authoritatively established as to business trusts
organized under the laws of one jurisdiction but operating or owning property in
other jurisdictions.  In states that have adopted legislation containing
provisions comparable to the Delaware Business Trust Act, it is believed that
the limitation of liability of beneficial owners provided by Delaware law should
be respected.  In those jurisdictions that have not adopted similar legislative
provisions, it is possible that a court might hold that the shareholders of the
Trusts are not entitled to the limitations of liability set forth in Delaware
law or


                                     -54-

<PAGE>

the Trust Instruments and, accordingly, that they may be personally liable 
for the obligations of the Trusts.

          In order to protect shareholders from such potential liability, the
Trust Instruments require that every written obligation of the Trusts or any
series thereof contain a statement to the effect that such obligation may only
be enforced against the assets of the Trusts or such series.  The Trust
Instruments also provides for indemnification from the assets of the relevant
series for all losses and expenses incurred by any shareholder by reason of
being or having been a shareholder, and that the Trusts shall, upon request,
assume the defense of any such claim made against such shareholder for any act
or obligation of the relevant series and satisfy any judgment thereon from the
assets of that series.

          As a result, the risk of a shareholder of the Funds in those Trusts
incurring financial loss on account of shareholder liability is limited to
circumstances in which the Fund itself would be unable to meet its obligations. 
The Trusts believe that the risk of personal liability to shareholders of the
Fund is therefore remote.  The trustees intend to conduct the operations of the
Trusts and the Funds so as to avoid, to the extent possible, liability of
shareholders for liabilities of the Trusts or the Funds.

          MASSACHUSETTS BUSINESS TRUST INFORMATION.  Under Massachusetts law,
shareholders of the Berger Small Cap Value Fund could, under certain
circumstances, be held personally liable for the obligations of the Fund. 
However, the Declaration of Trust of the Berger Omni Investment Trust, of which
the Fund is a series, disclaims shareholder liability for acts or obligations of
the Fund and requires that notice of such disclaimer be given in each agreement,
obligation, or instrument entered into or executed by the Fund or the trustees. 
The Declaration of Trust provides for indemnification out of the property of the
Fund for all loss and expense of any shareholder of the Fund held personally
liable for the obligations of the Fund.  Accordingly, the risk of a shareholder
incurring financial loss on account of shareholder liability is limited to
circumstances in which the Fund would be unable to meet its obligations.  The
Trust believes that the risk of personal liability to shareholders of the Fund
is therefore remote.  The trustees intend to conduct the operations of the Fund
to avoid, to the extent possible, liability of shareholders for liabilities of
the Fund. 

          CORPORATE GOVERNANCE INFORMATION PERTAINING TO ALL FUNDS.  None of the
Funds is required to hold annual shareholder meetings unless required by the
Investment Company Act of 1940 or other applicable law or unless called by the
directors or trustees.  If shareholders owning at least 10% of the outstanding
shares of the Berger 100 Fund, the Berger Growth and Income Fund or any of the
Trusts so request, a special shareholders' meeting of that Fund or Trust will be
held for the purpose of considering the removal of a director or trustee, as the
case may be.  Special meetings will be held for other purposes if the holders of
at least 25% of the outstanding shares of any of those Funds or Trusts so
request.  Subject to certain limitations, the Funds/Trusts will facilitate
appropriate communications by shareholders desiring to call a special meeting
for the purpose of considering the removal of a director or trustee.

          Shareholders of the Funds and, where applicable, the other series of
the same business trust, generally vote separately on matters relating to those
respective series, although they vote together and with the holders of any other
series of the same business trust in the election of trustees of the trust and
on all matters relating to the trust as a whole.  Each full share of each Fund
has one vote.  

          Shares of the Funds have non-cumulative voting rights, which means
that the holders of more than 50% of the shares voting for the election of
directors or trustees can elect 100% of the directors or trustees if they choose
to do so and, in such event, the holders of the remaining less than 50% of the
shares voting for the election of directors or trustees will not be able to
elect any person or persons as directors or trustees.  

          Shares of the Funds have no preemptive rights. There are no sinking
funds or arrearage provisions which may affect the rights of the Fund shares. 
Fund shares have no subscription rights or


                                     -55-

<PAGE>

conversion rights, except that shareholders of any class of the Berger Small 
Cap Value Fund may convert their shares into shares of any other class of the 
Fund in the event and only in the event the shareholder ceases to be eligible 
to purchase or hold shares of the original class, or becomes eligible to 
purchase shares of a different class, by reason of a change in the 
shareholder's status under the conditions of eligibility in effect for such 
class at that time.  Shares of the Funds may be transferred by endorsement, 
or other customary methods, but none of the Funds is bound to recognize any 
transfer until it is recorded on its books. 

MORE INFORMATION ON SPECIAL FUND STRUCTURES

          MULTI-CLASS.  All of the Funds are permitted to divide their shares
into classes.  However, currently, only the Berger Small Cap Value Fund has
divided its shares into classes and has two classes of shares outstanding, the
Investor Shares covered by this SAI and the Institutional Shares offered through
a separate Prospectus and SAI.  The Berger Small Cap Value Fund implemented its
multi-class structure by adopting a Rule 18f-3 Plan under the 1940 Act
permitting it to issue its shares in classes.  The Fund's Rule 18f-3 Plan
governs such matters as class features, dividends, voting, allocation of income
and expenses between classes, exchange and trustee monitoring of the Plan.  Each
class is subject to such investment minimums and other conditions of eligibility
as are set forth in the relevant prospectus for the class, as it may be amended
from time to time.   Institutional Shares are designed for institutional,
individual and other investors willing to maintain a higher minimum account
balance, currently set at $100,000.  Information concerning Institutional Shares
is available from the Fund at 1-800-706-0539.  

           Subject to the Trust's Declaration of Trust and any other applicable
provisions, the trustees of the Trust have the authority to create additional
classes, or change existing classes, from time to time, in accordance with Rule
18f-3 under the Act.

          MASTER/FEEDER.  Unlike other mutual funds that directly acquire and
manage their own portfolios of securities, the Berger/BIAM International Fund
(referred to as a feeder fund) seeks to achieve its investment objective by
investing all of its investable assets in the Berger/BIAM International
Portfolio (referred to as a master fund).  This two-tier structure is commonly
known as a master/feeder.  The Fund has the same investment objective and
policies as the Portfolio.  The Fund will invest only in the Portfolio, and the
Fund's shareholders will therefore acquire only an indirect interest in the
investments of the Portfolio.  The master/feeder fund structure is still
relatively new and lacks a substantial history.

          In addition to selling a beneficial interest to the Fund, the
Portfolio may sell beneficial interests to other mutual funds or institutional
investors (that is, other feeder funds).  Such investors will invest in the
Portfolio on the same terms and conditions and will pay their proportionate
share of the Portfolio's expenses.  However, the other investors investing in
the Portfolio are not required to issue their shares at the same public offering
price as the Fund due to potential differences in expense structures. 
Accordingly, investors in the Fund should be aware that these differences may
result in differences in returns experienced by investors in the different funds
that invest in the Portfolio.  Such differences in returns are common in this
type of mutual fund structure and are also present in other mutual fund
structures.  Information concerning other investors in the Portfolio (for
example, other feeder funds) is available from the Fund at 1-800-706-0539. 
Shareholders willing to maintain an account balance of not less than$1,000,000
may want to consider the International Equity Fund (designed for eligible trusts
or bank trust departments) or the Berger/BIAM International CORE Fund, which are
both other feeder funds that, like the Fund, invest all of their investable
assets in the Portfolio.

          The investment objective of the Fund may not be changed without the
approval of the Fund's shareholders.  The investment objective of the Portfolio
may not be changed without the approval of the investors in the Portfolio,
including the Fund.  If the objective of the Portfolio changes and the
shareholders of the Fund do not approve a parallel change in the Fund's
investment objective, the


                                     -56-

<PAGE>

trustees of the Trust will consider other alternatives, including seeking an 
alternative investment vehicle or directly retaining the Fund's own 
investment advisor. 

          Smaller funds investing in the Portfolio may be materially affected by
the actions of larger funds investing in the Portfolio.  For example, if a
larger fund invests or withdraws from the Portfolio, the remaining funds may
experience lower or higher pro rata operating expenses.  Lower returns could
possibly result from a large withdrawal.  However, this possibility also exists
for traditionally structured funds which have large or institutional investors. 
Also, a fund with a greater pro rata ownership in the Portfolio could have
effective voting control over the operations of the Portfolio.

          Whenever the Fund is requested to vote as an investor in the Portfolio
on matters pertaining to the Portfolio (other than a vote by the Fund to
continue the operation of the Portfolio upon the withdrawal of another investor
in the Portfolio), the Fund will hold a meeting of its shareholders and will
cast all of its votes as an investor in the Portfolio in the same proportion as
directed by the votes of the Fund's shareholders.  Fund shareholders who do not
vote will not affect the votes cast by the Fund at the meeting of the Portfolio
investors.  The percentage of the votes representing the Fund's shareholders who
do not vote will be voted by the Fund in the same proportion as the Fund's
shareholders who do, in fact, vote.

          The Fund may withdraw its investment in the Portfolio at any time, if
the trustees of the Trust determine that it is in the best interests of the Fund
to do so.  Certain changes in the Portfolio's investment objective, policies and
limitations may require the Fund to withdraw its investment in the Portfolio. 
Upon any such withdrawal, the trustees would consider what action might be
taken, including investing the Fund's assets in another pooled investment entity
having the same investment objective and policies as the Fund or retaining an
investment advisor to manage the Fund's assets in accordance with the investment
policies described above with respect to the Portfolio.  Any such withdrawal
could result in a distribution in-kind of portfolio securities (as opposed to a
cash distribution) from the Portfolio.  If securities are distributed, the Fund
could incur brokerage, tax or other charges in converting the securities to
cash.  In addition, a distribution in-kind may adversely affect the liquidity of
the Fund.

          The trustees of the Berger/BIAM Worldwide Funds Trust and the
Berger/BIAM Worldwide Portfolios Trust are the same individuals.  A majority of
the trustees of each of those Trusts who are not "interested persons" (as
defined in the Investment Company Act of 1940) of either Trust have adopted
written procedures reasonably appropriate to deal with potential conflicts of
interest arising from the fact that the same individuals are trustees of both
Trusts, up to and including creating a new board of trustees for one or the
other of the Trusts.

DISTRIBUTION

          Berger Distributors, Inc., as the Funds' Distributor, is the principal
underwriter of all the Funds' shares.  The Distributor is a wholly-owned
subsidiary of Berger Associates.  The Distributor is a registered broker-dealer
under the Securities Exchange Act of 1934 and is a member of the National
Association of Securities Dealers, Inc.  The Distributor acts as the agent of a
Fund in connection with the sale of the Fund's shares in all states in which the
shares are eligible for sale and in which the Distributor is qualified as a
broker-dealer.

          Each of the Funds and the Distributor are parties to a Distribution
Agreement that continues through April 1998 or 1999, and thereafter from year to
year if such continuation is specifically approved at least annually by the
directors or trustees or by vote of a majority of the outstanding shares of the
Fund and in either case by vote of a majority of the directors or trustees who
are not "interested persons" (as that term is defined in the Investment Company
Act of 1940) of the Fund or the Distributor.  The Distribution Agreement is
subject to termination by the Fund or the Distributor on 60 days' prior written
notice, and terminates automatically in the event of its assignment.  Under the
Distribution Agreement, the Distributor continuously offers shares of the Funds
and solicits orders to purchase Fund shares at net asset value.  The Distributor
is not compensated for its services under the Distribution Agreement, but may be
reimbursed by Berger Associates for its costs in distributing Fund shares.

          The Funds have each filed with the Securities and Exchange Commission,
Washington, D.C., a Registration Statement under the Securities Act of 1933, as
amended, with respect to the securities of the Funds of which this Statement of
Additional Information is a part. If further information is desired with respect
to any of the Funds or such securities, reference is made to the Registration
Statements and the exhibits filed as a part thereof.


YEAR 2000

          Mutual funds and businesses around the world depend on smooth
functioning computer systems.  Many of those systems need to be modified to
distinguish the difference between the year 1900 and the year 2000.  The
adviser, distributor, shareholder servicing and transfer agent, custodian and
certain other service providers to the Funds have reported that each expects to
modify its systems, as necessary, prior to January 1, 2000, to address the
so-called "year 2000 problem."  However, there can be no assurance that the
problems will be corrected in all respects and that the Funds' operations and
services provided to shareholders will not be adversely affected.

                                     APPENDIX A

HIGH-YIELD/HIGH-RISK SECURITIES  

          Each of the Funds may invest in convertible securities of any quality,
including unrated securities or securities rated below investment grade (Ba or
lower by Moody's, BB or lower by S&P).  However, a Fund will not purchase any
security in default at the time of purchase.  None of the Funds will invest more
than 20% of the market value of its assets at the time of purchase in
convertible securities rated below investment grade.  

          Securities rated below investment grade are subject to greater risk
that adverse changes in the financial condition of their issuers or in general
economic conditions, or an unanticipated rise in interest rates, may impair the
ability of their issuers to make payments of interest and principal or
dividends.  The market prices of lower grade securities are generally less
sensitive to interest rate changes than higher-rated investments, but more
sensitive to economic changes or individual corporate developments.  Periods of
economic uncertainty and change can be expected to result in volatility of
prices of these securities.  Lower rated securities also may have less liquid
markets than higher rated securities, and their liquidity as well as their value
may be adversely affected by poor economic conditions.  Adverse publicity and
investor perceptions as well as new or proposed laws may also have a negative
impact on the market for high-yield/high-risk bonds.  In the event of an
unanticipated default, a Fund will experience a reduction in its income and
could expect a decline in the market value of the securities affected.  The
prices of these securities may be more volatile and the markets for them may be
less liquid than those for higher-rated securities. 

          Unrated securities, while not necessarily of lower quality than rated
securities, may not have as broad a market.  Unrated securities will be included
in a Fund's percentage limits for investments rated below investment grade,
unless the Fund's advisor deems such securities to be the equivalent of
investment grade.  If securities purchased by a Fund are downgraded following
purchase, or if other circumstances cause the Fund to exceed its percentage
limits on assets invested in securities rated below investment grade, the
director or trustees of the Fund, in consultation with the Fund's advisor, will
determine what action, if any, is appropriate in light of all relevant
circumstances.  

          Relying in part on ratings assigned by credit agencies in making
investments will not protect a Fund from the risk that the securities will
decline in value, since credit ratings represent evaluations of the safety of
principal, dividend and/or interest payments, and not the market values of such
securities.  Moreover, such ratings may not be changed on a timely basis to
reflect subsequent events.

          Although the market for high-yield debt securities has been in
existence for many years and from time to time has experienced economic
downturns, this market has involved a significant increase in the use of
high-yield debt securities to fund highly leverage corporate acquisitions and
restructurings.  Past experience may not, therefore, provide an accurate
indication of future performance of the high-yield debt securities market,
particularly during periods of economic recession.

          Expenses incurred in recovering an investment in a defaulted security
may adversely affect a Fund's net asset value.  Moreover, the reduced liquidity
of the secondary market for such securities may adversely affect the market
price of, and the ability of a Fund to value, particular securities at certain
times, thereby making it difficult to make specific valuation determinations.

CORPORATE BOND RATINGS

          The ratings of fixed-income securities by Moody's and Standard &
Poor's are a generally accepted measurement of credit risk.  However, they are
subject to certain limitations.  Ratings are generally based upon historical
events and do not necessarily reflect the future.  In addition, there is a
period of time


                                     -60-

<PAGE>

between the issuance of a rating and the update of the rating, during which 
time a published rating may be inaccurate.

KEY TO MOODY'S CORPORATE RATINGS

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

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

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

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

          Ba-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 good and bad times over the future.  Uncertainty of position
characterizes bonds of this class.

          B-Bonds which are rated B generally lack characteristics of the
desirable investment.  Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small.

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

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

          Note:  Moody's applies numerical modifiers, 1, 2 and 3 in each generic
rating classification from Aa through B in 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
category.

KEY TO STANDARD & POOR'S CORPORATE RATINGS

          AAA-Debt rated AAA has the highest rating assigned by Standard &
Poor's.  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, B, CCC, CC AND C-Debt rated BB, B, CCC, CC and C is regarded, on
balance, as predominantly speculative with respect to capacity to pay interest
and repay principal in accordance with the terms of the obligation.  BB
indicates the lowest degree of speculation and C the highest degree of
speculation.  While such debt will likely have some quality and protective
characteristics, these are out-weighed by the large uncertainties or major risk
exposures to adverse conditions.

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

          D-Debt rated D is in default, and payment of interest and/or repayment
of principal is in arrears.

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