The Fund's Goal and Principal Investment Strategies

The Fund aims for capital appreciation. In pursuing its goal, the Fund invests
at least 80% of its assets in common stocks of companies in the information
technology group of industries, such as software, hardware, computer consulting
services, communications and Internet services and products. The Fund's
investment manager analyzes trends in information technology spending and
demand, then identifies companies it believes are best positioned to benefit
from those trends. The Fund generally invests the remainder of its assets in
information technology-related companies whose stock price the investment
manager believes is undervalued relative to their assets, earnings, cash flow or
business franchise.

The Fund's investment manager generally looks for companies:

o  That dominate their industries or a particular market segment

o  That have or are developing products or services that represent significant
   technological advancements or improvements

o  That have strong fundamentals, strong management and strong product
   positioning.

The Fund primarily invests in common stocks. The Fund is free to invest in
companies of any size market capitalization. The Fund's investment manager will
generally sell a security when it no longer meets the manager's investment
criteria or when it has met the manager's expectations for appreciation.

Principal Risks


You may be interested in the Fund if you are comfortable with
above-average risk and intend to make a long-term investment commitment. Like
all managed funds, there is a risk that the investment manager's strategy for
managing the Fund may not achieve the desired results. In addition, the price of
common stock moves up and down in response to corporate earnings and
developments, economic and market conditions and anticipated events. As a
result, the price of the Fund's investments may go down and you could lose money
on your investment.


Given the Fund's concentration in industries that are rapidly changing, its
share price may fluctuate more than that of funds invested in more stable
industries. Companies in the information technology industries may have narrow
product lines and their products and services are often subject to intense
competition and rapid obsolescence.


Because the Fund's investments are focused in the information technology sector,
the Fund is more susceptible to adverse events and market pressures impacting
the industries included in that sector, which may pose greater liquidity risk.


See "Investment Techniques, Securities and Associated Risks" later in this
prospectus for more information on principal risks and other risks.

The Fund's Past Performance

The information below shows the Fund's performance since it began operations
through December 31, 1999. These returns include reinvestment of all dividends
and capital gains distributions and reflect Fund expenses. As with all mutual
funds, past performance does not guarantee future results.

Year-by-year returns show how the Fund's performance has varied by illustrating
the differences for each full calendar year since the Fund began.

WORST QUARTER:  9/30/98                       (9.95)%
</TABLE>


(1) Calendar year-to-date through March 31, 2000 totaled 15.44%. Recent market
volatility has significantly impacted performance.


Average annual total return is a measure of the Fund's performance over time.
The Fund's average annual return is compared with the Wilshire 5000 Index
(Wilshire 5000). While the Fund does not seek to match the returns of the
Wilshire 5000, this index is a good indicator of general stock market
performance. You may not invest in the Wilshire 5000 and unlike the Fund, it
does not incur fees or charges.

reduced the Fund's return.

</TABLE>

* The 1% redemption fee referenced in the table will be imposed on shares
exchanged if held less than 6 months, since an exchange is treated as a
redemption followed by a purchase.

(1) Effective October 1, 1999, the investment advisory fee charged to the Fund
was reduced to the following rates of average daily net assets; 0.85% of the
first $500 million; 0.80% of the next $500 million and 0.75% in excess of $1
billion. The amount shown reflects the restated advisory fees.

(2) "Other expenses" are based on estimated expenses of the Investor Shares
class and include transfer agency fees, shareholder report expenses,
registration fees and custodian fees. Effective October 1, 1999, Berger LLC
eliminated the administrative fee charged to the Fund. The fee amount shown
reflects the restated expenses.

Understanding Expenses

Annual Fund operating expenses are paid by the Fund. As a result, they reduce
the Fund's return. Fund expenses include management fees, 12b-1 fees and
administrative costs such as shareholder recordkeeping and reports, custodian
and pricing services and registration fees.

Example Costs

The following example helps you compare the cost of investing in the Fund to the
cost of investing in other mutual funds by showing what your costs may be over
time. It uses the same assumptions that other funds use in their prospectuses:

o   $10,000 initial investment

o   5% total return for each year

o   Fund operating expenses remain the same for each period

o   Redemption after the end of each period

Your actual costs may be higher or lower, so this example should be used for
comparison only. Based on these assumptions your costs at the end of each period
would be:

The Fund's Goal and Principal Investment Strategies

The Fund aims for capital appreciation. In pursuing that goal, the Fund
primarily invests in the common stocks of companies with potential for
significant earnings growth.

The Fund focuses on leading-edge companies with new ideas, technologies or
methods of doing business. Its investment manager seeks companies it believes
have the potential to change the direction or dynamics of the industries in
which they operate or significantly influence the way businesses or consumers
conduct their affairs.

The Fund's investment manager generally looks for companies:

o   In business sectors characterized by rapid change, regardless of the
    company's size

o   With favorable long-term growth potential due to their new or innovative
    products or services

o   With management and financial strength to fulfill their vision and grow
    their business.

The Fund invests in common stocks, both domestic and foreign, and other
securities with equity features, such as convertible securities and preferred
stocks. Due to the Fund's focus on companies with the characteristics described
above, the Fund generally is weighted toward small market capitalization
companies, although it is free to invest in companies with larger market
capitalizations as well. The Fund's investment manager will generally sell a
security when it no longer meets the manager's investment criteria or when it
has met the manager's expectations for appreciation. The Fund's investment
manager may actively trade the portfolio in pursuit of the Fund's goal.

Principal Risks

You may be interested in the Fund if you are comfortable with above-average risk
and intend to make a long-term investment commitment. Like all managed funds,
there is a risk that the investment manager's strategy for managing the Fund may
not achieve the desired results. In addition, the price of common stock moves up
and down in response to corporate earnings and developments, economic and market
conditions and anticipated events. As a result, the price of the Fund's
investments may go down and you could lose money on your investment.


Given the Fund's weighting toward small companies in rapidly changing
industries, its share price may fluctuate more than that of funds invested in
larger companies or more stable industries. Small companies may pose greater
market, liquidity and information risks due to narrow product lines, limited
financial resources, less depth in management or a limited trading market for
their stocks. In addition, products and services in rapidly changing industries
may be subject to intense competition and rapid obsolescence and may require
regulatory approvals prior to their use. The Fund's investments are often
focused in a small number of business sectors, which may pose greater market and
liquidity risks. In addition, the Fund's active trading will cause the Fund to
have an increased portfolio turnover rate. Higher turnover rates may result in
higher brokerage costs to the Fund and in higher net taxable gains for you as an
investor.


See "Investment Techniques, Securities and Associated Risks" later in this
prospectus for more information on principal risks and other risks.

charged to the Fund. The fee amount shown reflects the restated expenses.

Understanding Expenses

Annual Fund operating expenses are paid by the Fund. As a result, they reduce
the Fund's return. Fund expenses include management fees, 12b-1 fees and
administrative costs such as shareholder recordkeeping and reports, custodian
and pricing services and registration fees.

Example Costs

The following example helps you compare the cost of investing in the Fund to the
cost of investing in other mutual funds by showing what your costs may be over

o    $10,000 initial investment

o    5% total return for each year

o    Fund operating expenses remain the same for each period

o    Redemption after the end of each period

Your actual costs may be higher or lower, so this example should be used for
comparison only. Based on these assumptions your costs at the end of each period
would be:

The Fund's Goal and Principal Investment Strategies

The Fund aims for capital appreciation. In pursuing that goal, the Fund
primarily invests in the common stocks of companies with superior potential for
strong earnings growth.


This non-diversified Fund normally invests in a core portfolio of 20-30 common
stocks selected by the Fund's four co-portfolio managers. Each co-portfolio
manager selects a portion of the stocks that comprise the portfolio. The stock
selection focuses on companies of any size whose growth potential is not yet
fully reflected in the company's stock price.


The Fund's investment manager generally looks for companies with:

o    Solid fundamental growth opportunities and that are market share leaders in
     their industries or have the potential to develop a large market for their
     products and services

o    Strong, capable management teams with clearly defined strategies for
     revenue and earnings growth

o    A catalyst for positive earnings developments such as evolving product
     cycles, special situations or changing economic conditions.

The Fund's investment manager will generally sell a security when it no longer
meets the manager's investment criteria or when it has met the manager's
expectations for appreciation. The Fund's investment manager may actively trade
the portfolio in pursuit of the Fund's goal. Due to this and the Fund's
relatively small number of holdings, the annual portfolio turnover rate may be
higher than other mutual funds.

Principal Risks

You may be interested in the Fund if you are comfortable with above-average risk
and intend to make a long-term investment commitment. Like all managed funds,
there is a risk that the investment manager's strategy for managing the Fund may
not achieve the desired results. In addition, the price of common stock moves up
and down in response to corporate earnings and developments, economic and market
conditions and anticipated events. As a result, the price of the Fund's
investments may go down and you could lose money on your investment.


The Fund's share price may fluctuate more than the market in general and most
equity funds due to its ability as a non-diversified fund to take larger
positions in a smaller number of companies. As a result, the gains or losses on
a single stock will have a greater impact on the Fund's share price. The Fund's
investments are often focused in a small number of business sectors, which may
pose greater market and liquidity risks. In addition, the Fund's active trading
will cause the Fund to have an increased portfolio turnover rate. Higher
turnover rates may result in higher brokerage costs to the Fund and in higher
net taxable gains for you as an investor.


See "Investment Techniques, Securities and Associated Risks" later in this
prospectus for more information on principal risks and other risks.

The Fund's Past Performance


The information below shows the Fund's performance since it began operations
through December 31, 1999. These returns include reinvestment of all dividends
and capital gains distributions and reflect Fund expenses. As with all mutual
funds, past performance does not guarantee future results.


Year-by-year returns show you how the Fund's performance has varied by
illustrating the differences for each full calendar year since the Fund began.

Average annual total return is a measure of the Fund's performance over time.
The Fund's average annual return is compared with the Standard & Poor's 500
Index (S&P 500). While the Fund does not seek to match the returns of the S&P
500, this index is a good indicator of general stock market performance. You may
not invest in the S&P 500 and unlike the Fund, it does not incur fees or
charges.

(1) Effective October 1, 1999, the investment advisory fee charged to the Fund
was reduced to the following rates of average daily net assets; 0.75% of the
first $500 million; 0.70% of the next $500 million and 0.65% in excess of $1
billion. The amount shown reflects the restated advisory fees.

(2) Effective October 1, 1999, Berger LLC eliminated the administrative fee
charged to the Fund. The fee amount shown reflects the restated expenses.

Understanding Expenses

Annual Fund operating expenses are paid by the Fund. As a result, they reduce
the Fund's return. Fund expenses include management fees, 12b-1 fees and
administrative costs such as shareholder recordkeeping and reports, custodian
and pricing services and registration fees.

Example Costs

The following example helps you compare the cost of investing in the Fund to the
cost of investing in other mutual funds by showing what your costs may be over
time. It uses the same assumptions that other funds use in their prospectuses:

o    $10,000 initial investment

The Fund's Goal and Principal Investment Strategies

The Fund aims for capital appreciation. In pursuing that goal, the Fund
primarily invests in the common stocks of small companies with the potential for
rapid earnings growth.

The Fund's stock selection focuses on companies that either occupy a dominant
position in an emerging industry or have a growing market share in a larger,
fragmented industry.

The Fund's investment manager generally looks for companies with:

o    A proprietary technology, product or service that may enable the company to
     be a market share leader

o    Strong entrepreneurial management with clearly defined strategies for
     growth

o    Relatively strong balance sheets.

Under normal circumstances, the Fund invests at least 65% of its assets in
equity securities of companies whose market capitalization, at the time of
initial purchase, is less than the 12-month average of the maximum market
capitalization for companies included in the Russell 2000 Index (Russell 2000).
This average is updated monthly. The Fund's investment manager will generally
sell a security when it no longer meets the manager's investment criteria or
when it has met the manager's expectations for appreciation. The Fund's
investment manager may actively trade the portfolio in pursuit of the Fund's
goal.

Principal Risks

You may be interested in the Fund if you are comfortable with above-average risk
and intend to make a long-term investment commitment. Like all managed funds,
there is a risk that the investment manager's strategy for managing the Fund may
not achieve the desired results. In addition, the price of common stock moves up
and down in response to corporate earnings and developments, economic and market
conditions and anticipated events. As a result, the price of the Fund's
investments may go down and you could lose money on your investment.


The Fund's share price may fluctuate more than that of funds primarily invested
in stocks of mid-sized and large companies. Small company securities may
underperform as compared to the securities of larger companies. They may also
pose greater market, liquidity and information risks due to narrow product
lines, limited financial resources, less depth in management or a limited
trading market for their stocks. The Fund's investments are often focused in a
small number of business sectors, which may pose greater market and liquidity
risks. In addition, the Fund's active trading will cause the Fund to have an
increased portfolio turnover rate. Higher turnover rates may result in higher
brokerage costs to the Fund and in higher net taxable gains for you as an
investor.

prospectus for more information on principal risks and other risks.

The Fund's Goal and Principal Investment Strategies


The Fund aims for capital appreciation. In pursuing that goal, the Fund
primarily invests in the common stocks of mid-sized companies with the potential
for strong earnings growth.

Stock selection focuses on companies that commit their resources to innovative
products or services for unique, changing or rapidly growing markets.

The Fund's investment manager generally looks for companies with:

o    Strong revenue and earnings growth fundamentals and dominant market share
     in their industry or business sector

o    Strong management teams with established organizational structures

o    Solid balance sheets and the ability to efficiently finance their growth
     through sufficient resources and access to capital.

Under normal circumstances, the Fund invests at least 65% of its assets in
equity securities of companies whose market capitalization falls, at the time of
initial purchase, within a range of $1 billion to the 12-month average of the
maximum market capitalization for companies included in the Standard & Poor's
Mid Cap 400 Index (S&P 400). This average is updated monthly. The Fund's
investment manager will generally sell a security when it no longer meets the
manager's investment criteria or when it has met the manager's expectations for
appreciation. The Fund's investment manager may actively trade the portfolio in
pursuit of the Fund's goal.

Principal Risks

You may be interested in the Fund if you are comfortable with above-average risk
and intend to make a long-term investment commitment. Like all managed funds,
there is a risk that the investment manager's strategy for managing the Fund may
not achieve the desired results. In addition, the price of common stock moves up
and down in response to corporate earnings and developments, economic and market
conditions and anticipated events. As a result, the price of the Fund's
investments may go down and you could lose money on your investment.


The Fund's share price may fluctuate more than that of funds primarily invested
in stocks of large companies. Mid-sized companies may pose greater market,
liquidity and information risks due to narrow product lines, limited financial
resources, less depth in management or a limited trading market for their
stocks. The Fund's investments are often focused in a small number of business
sectors, which may pose greater market and liquidity risks. In addition, the
Fund's active trading will cause the Fund to have an increased portfolio
turnover rate. Higher turnover rates may result in higher brokerage costs to the
Fund and in higher net taxable gains for you as an investor.


See "Investment Techniques, Securities and Associated Risks" later in this
prospectus for more information on principal risks and other risks.

The Fund's Past Performance


The information below shows the Fund's performance since it began operations
through December 31, 1999. These returns include reinvestment of all dividends
and capital gains distributions and reflect Fund expenses. As with all mutual
funds, past performance does not guarantee future results.


Year-by-year returns show you how the Fund's performance has varied by
illustrating the differences for each full calendar year since the Fund began.

not invest in the S&P 400 and unlike the Fund, it does not incur fees or
charges.

(1) Effective October 1, 1999, the investment advisory fee charged to the Fund
was reduced to the following rates of average daily net assets; 0.75% of the
first $500 million; 0.70% of the next $500 million and 0.65% in excess of $1
billion. The amount shown reflects the restated advisory fees.

(2) Effective October 1, 1999, Berger LLC eliminated the administrative fee
charged to the Fund. The fee amount shown reflects the restated expenses.

Understanding Expenses

Annual Fund operating expenses are paid by the Fund. As a result, they reduce
the Fund's return. Fund expenses include management fees, 12b-1 fees and
administrative costs such as shareholder recordkeeping and reports, custodian
and pricing services and registration fees.

Example Costs

The following example helps you compare the cost of investing in the Fund to the
cost of investing in other mutual funds by showing what your costs may be over
time. It uses the same assumptions that other funds use in their prospectuses:

o    $10,000 initial investment

o    5% total return for each year

o    Fund operating expenses remain the same for each period

o    Redemption after the end of each period

Your actual costs may be higher or lower, so this example should be used for
comparison only. Based on these assumptions your costs at the end of each period
would be:

The Fund's Goal and Principal Investment Strategies

The Fund aims for capital appreciation. In pursuing that goal, the Fund
primarily invests in the common stocks of mid-sized companies whose stock prices
are believed to be undervalued.

Investment selection focuses on companies that have fallen out of favor with the
market or are temporarily misunderstood by the investment community. To a lesser
degree, the Fund also invests in companies that demonstrate special situations
or turnarounds, meaning companies that have experienced significant business
problems but are believed to have favorable prospects for recovery.

The Fund's investment manager generally looks for companies with:

o    A low price relative to their assets, earnings, cash flow or business
     franchise

o    Products and services that give them a competitive advantage

o    Quality balance sheets and strong management.

The investment manager's philosophy is to weigh a security's downside risk
before considering its upside potential, which may help provide an element of
capital preservation. Under normal circumstances, the Fund invests at least 65%
of its assets in equity securities of mid-sized companies whose market
capitalization falls, at the time of initial purchase, within a range of $1
billion to the 12-month average of the maximum market capitalization for
companies included in the Standard & Poor's Mid Cap 400 Index (S&P 400). This
average is updated monthly. The Fund's investment manager will generally sell a
security when it no longer meets the manager's investment criteria or when it
has met the manager's expectations for appreciation. The Fund's investment
manager may actively trade the portfolio in pursuit of the Fund's goal.

Principal Risks

You may be interested in the Fund if you are comfortable with above-average risk
and intend to make a long-term investment commitment. Like all managed funds,
there is a risk that the investment manager's strategy for managing the Fund may
not achieve the desired results. In addition, the price of common stock moves up
and down in response to corporate earnings and developments, economic and market
conditions and anticipated events. As a result, the price of the Fund's
investments may go down and you could lose money on your investment.


The Fund's share price may fluctuate more than that of funds primarily invested
in large companies. Mid-sized companies may pose greater market, liquidity and
information risks due to narrow product lines, limited financial resources, less
depth in management or a limited trading market for their stocks. The Fund's
investments are often focused in a small number of business sectors, which may
pose greater market and liquidity risks. In addition, the Fund may invest in
certain securities with unique risks, such as special situations which could
present increased market and information risks. The Fund's active trading will
cause the Fund to have an increased portfolio turnover rate. Higher turnover
rates may result in higher brokerage costs to the Fund and in higher net taxable
gains for you as an investor.

prospectus for more information on principal risks and other risks.

The Fund's Goal and Principal Investment Strategies

The Fund aims for long-term capital appreciation. In pursuing that goal, the
Fund primarily invests in the common stocks of established companies with the
potential for growth.


Stock selection by the Fund's investment manager focuses on mid-sized to large
capitalization companies believed to have strong growth potential.


The Fund's investment manager generally looks for companies with:

o    Opportunities for rapid revenue and earnings growth

o    Large market potential for their products and services

o    Strong, capable management teams that have the vision necessary to increase
     their market share in growing industries.

The Fund's investment manager will generally sell a security when it no longer
meets the manager's investment criteria or when it has met the manager's
expectations for appreciation. The Fund's investment manager may actively trade
the portfolio in pursuit of the Fund's goal.

Principal Risks

You may be interested in the Fund if you are comfortable with the risks of
equity investing and intend to make a long-term investment commitment. Like all
managed funds, there is a risk that the investment manager's strategy for
managing the Fund may not achieve the desired results. In addition, the price of
common stock moves up and down in response to corporate earnings and
developments, economic and market conditions and anticipated events. As a
result, the price of the Fund's investments may go down and you could lose money
on your investment.


The Fund's investments may focus in a small number of business sectors, which
may pose greater market and liquidity risks. In addition, the Fund's active
trading will cause the Fund to have an increased portfolio turnover rate. Higher
turnover rates may result in higher brokerage costs to the Fund and in higher
net taxable gains for you as an investor.

(1) Effective October 1, 1999, the investment advisory fee charged to the Fund
was reduced to the following rates of average daily net assets; 0.75% of the
first $500 million; 0.70% of the next $500 million and 0.65% in excess of $1
billion. The amount shown reflects the restated advisory fees.

(2) Effective October 1, 1999, Berger LLC eliminated the administrative fee
charged to the Fund. The fee amount shown reflects the restated expenses.

Understanding Expenses

Annual Fund operating expenses are paid by the Fund. As a result, they reduce
the Fund's return. Fund expenses include management fees, 12b-1 fees and
administrative costs such as shareholder recordkeeping and reports, custodian
and pricing services and registration fees.

Example Costs

The following example helps you compare the cost of investing in the Fund to the
cost of investing in other mutual funds by showing what your costs may be over
time. It uses the same assumptions that other funds use in their prospectuses:

o    $10,000 initial investment

o    5% total return for each year

o    Fund operating expenses remain the same for each period

o    Redemption after the end of each period

Your actual costs may be higher or lower, so this example should be used for
comparison only. Based on these assumptions your costs at the end of each period
would be:

The Fund's Goal and Principal Investment Strategies

The Fund aims for long-term capital appreciation. In pursuing that goal, the
Fund primarily invests in a portfolio consisting of common stocks of
well-established foreign companies.

The portfolio's investment manager first identifies economic and business themes
that it believes provide a favorable framework for selecting stocks. Using
fundamental analysis, the investment manager then selects individual companies
best positioned to take advantage of opportunities presented by these themes.

The portfolio's investment manager generally looks for companies with:

o    Securities that are fundamentally undervalued relative to their long-term
     prospective earnings growth rates, their historic valuation levels and
     their competitors

o    Business operations predominantly in well-regulated and more stable
     foreign markets

o    Substantial size and liquidity, strong balance sheets, proven management
     and diversified earnings.


The Fund invests all of its assets in the Berger International Portfolio
(Portfolio), which has the same goals and policies as the Fund. The Portfolio
invests primarily in common stocks with 65% of its total assets in securities of
companies located in at least five different countries outside the United
States. Recently, the Portfolio has been weighted toward countries in Western
Europe, Australia and the Far East. However, it may also invest in other foreign
countries, including developing countries. A majority of the Portfolio's assets
are invested in mid-sized to large capitalization companies. The Portfolio's
investment manager will generally sell a security when it no longer meets the
manager's investment criteria or when it has met the manager's expectations for
appreciation.


See "Organization of the Berger Funds Family-Special Fund
Structures-Master/Feeder" later in this prospectus for more information on the
Fund's investment in the Portfolio.

Principal Risks


You may be interested in the Fund if you are comfortable with the risks of
international investing and intend to make a long-term investment commitment.
Like all managed funds, there is a risk that the investment manager's strategy
for managing the Fund may not achieve the desired results. In addition, the
price of common stock moves up and down in response to corporate earnings and
developments, economic and market conditions and anticipated events. As a
result, the price of the Fund's investments may go down and you could lose money
on your investment. There are additional risks with investing in foreign
countries, especially in developing countries--specifically, economic, currency,
liquidity, information, political and transaction risks. As a result of these
additional risks, the Fund may be more volatile than a domestic stock fund. In
addition, foreign stocks may not move in concert with the U.S. markets. The
Fund's investments are often focused in a small number of business sectors,
which may pose greater market and liquidity risks. In addition, the Fund may
invest in certain securities with unique risks, such as forward foreign currency
contracts, which may present hedging, credit, correlation, opportunity and
leverage risks.


See "Investment Techniques, Securities and Associated Risks" later in this
prospectus for more information on principal risks and other risks.

(2) Predecessor Performance: performance figures covering periods prior to

Portfolio's investment manager for periods before the Portfolio began
operations. This performance has been adjusted to reflect the increased expenses
expected in operating the Fund, net of fee waivers. The asset pool was not
registered with the SEC and was not subject to the investment restrictions
imposed on mutual funds. If the pool had been registered, its performance might
have been adversely affected.

The Fund's Goals and Principal Investment Strategies

The Fund aims for capital appreciation and has a secondary goal of investing in
securities that produce current income for the portfolio. In pursuing these
goals, the Fund primarily invests in the securities of well-established, growing
companies. The Fund's secondary goal may be changed at any time without a
shareholder vote.

Security selection focuses on the common stocks, convertible securities and
preferred stocks of companies that have demonstrated a pattern of growth and
stability and are also expected to provide current income.

The Fund's investment manager generally looks for companies with:

o    Opportunities for good revenue and earnings growth

o    Strong market positions for their products and services

o    Strong, seasoned management teams with well-established and clearly
     defined strategies.

Common stock of companies with mid-sized to large market capitalizations usually
constitutes a majority of the Fund's investments. The Fund primarily invests in
income producing securities to provide a level of protection from price
volatility that may not be present when income is not a consideration. The Fund
may invest up to 20% of its assets in convertible securities rated below
investment grade (BB or lower by S&P, Ba or lower by Moody's). The Fund's
investment manager will generally sell a security when it no longer meets the
manager's investment criteria or when it has met the manager's expectations for
appreciation. The Fund's investment manager may actively trade the portfolio in
pursuit of the Fund's goal.

Principal Risks

You may be interested in the Fund if you are comfortable with the risks of
equity and fixed-income investing and intend to make a long-term investment
commitment. Like all managed funds, there is a risk that the investment
manager's strategy for managing the Fund may not achieve the desired results. In
addition, the price of common stock moves up and down in response to corporate
earnings and developments, interest rate movements, economic and market
conditions and anticipated events. As a result, the price of the Fund's
investments may go down and you could lose money on your investment.


To the extent the Fund invests in fixed-income securities it takes on different
risks, including movements in interest rates and default on payment of principal
or interest. In addition, the Fund may invest in convertible securities rated
below investment grade, which may pose greater market, interest rate, prepayment
and credit risks. These issuers are less financially secure, and are more likely
to be hurt by interest rate movements. When dividend yields and interest rates
are low, the Fund's income distributions to you may be reduced or eliminated. In
addition, the Fund's active trading will cause the Fund to have an increased
portfolio turnover rate. Higher turnover rates may result in higher brokerage
costs to the Fund and in higher net taxable gains for you as an investor.

prospectus for more information on principal risks and other risks.

(1) Effective October 1, 1999, the investment advisory fee charged to the Fund
was reduced to the following rates of average daily net assets; 0.75% of the
first $500 million; 0.70% of the next $500 million and 0.65% in excess of $1
billion. The amount shown reflects the restated advisory fees.

(2) Effective October 1, 1999, Berger LLC eliminated the administrative fee
charged to the Fund. The fee amount shown reflects the restated expenses.

Understanding Expenses

Annual Fund operating expenses are paid by the Fund. As a result, they reduce
the Fund's return. Fund expenses include management fees, 12b-1 fees and
administrative costs such as shareholder recordkeeping and reports, custodian
and pricing services and registration fees.

Example Costs

The following example helps you compare the cost of investing in the Fund to the
cost of investing in other mutual funds by showing what your costs may be over
time. It uses the same assumptions that other funds use in their prospectuses:

o    $10,000 initial investment

o    5% total return for each year

o    Fund operating expenses remain the same for each period

o    Redemption after the end of each period

Your actual costs may be higher or lower, so this example should be used for
comparison only. Based on these assumptions your costs at the end of each period
would be:

The Fund's Goals and Principal Investment Strategies

The Fund aims for capital appreciation and current income. In pursuing these
goals, the Fund primarily invests in a diversified group of domestic equity and
fixed-income securities.

The allocation between equity and fixed-income securities is based upon the
investment manager's assessment of available investment opportunities and
relevant market, economic and financial factors.

The Fund's investment manager generally looks for companies with:

o    Reasonably priced equity securities with strong, consistent and
     predictable earnings growth rates

o    Strong, seasoned management teams and competitive products or services

o    Well-capitalized balance sheets.

The Fund's equity investments consist primarily of common stocks of companies
with mid-sized to large market capitalizations. The Fund's fixed-income
investments are a variety of income-producing securities, such as short- to
long-term corporate and government debt securities, convertible securities,
preferred stocks and mortgage-backed securities. The investment manager believes
its investment style emphasizing equity securities offers shareholders the
opportunity for capital appreciation along with a reasonable level of capital
preservation. Normally, equity securities are expected to range from 45% to 65%
of the Fund's total assets. However, it is the Fund's policy to invest at least
25% of its total assets in fixed-income senior securities and at least 25% in
equity securities. The Fund may invest up to 20% of its assets in convertible
securities rated below investment grade (BB or lower by S&P, Ba or lower by
Moody's).

The Fund's investment manager will generally sell a security when it no longer
meets the manager's investment criteria or when it has met the manager's
expectations for appreciation. The Fund's investment manager may actively trade
the equity portion of the portfolio in pursuit of the Fund's goal. When this
occurs, the annual portfolio turnover rate may be higher than other comparable
funds.

Principal Risks


You may be interested in the Fund if you are comfortable with the risks of
equity and fixed-income investing and intend to make a long-term investment
commitment. Like all managed funds, there is a risk that the investment
manager's strategy for managing the Fund may not achieve the desired results. In
addition, the price of common stock moves up and down in response to corporate
earnings and developments, interest rate movements, economic and market
conditions and anticipated events. As a result, the price of the Fund's
investments may go down and you could lose money on your investment. The Fund
may be riskier than other balanced funds that invest more heavily in
fixed-income securities.

To the extent the Fund invests in fixed-income securities it takes on different
risks, including movements in interest rates and default on payment of principal
or interest, as well as market and call risks. In addition, the Fund may invest
in convertible securities rated below investment grade, which may pose greater
market, interest rate, prepayment and credit risks. These issuers are less
financially secure, and are more likely to be hurt by interest rate movements.
When interest rates are low, the Fund's income distributions to you may be
reduced or eliminated. In addition, the Fund's active trading will cause the
Fund to have an increased portfolio turnover rate. Higher turnover rates may
result in higher brokerage costs to the Fund and in higher net taxable gains for
you as an investor.


See "Investment Techniques, Securities and Associated Risks" later in this
prospectus for more information on principal risks and other risks.

The Fund's Past Performance

The information below shows the Fund's performance since it began operations
through December 31, 1999. These returns include reinvestment of all dividends
and capital gains distributions and reflect Fund expenses. As with all mutual
funds, past performance does not guarantee future results.

illustrating the differences for each full calendar year since the Fund began.

Average annual total return is a measure of the Fund's performance over time.
The Fund's average annual return is compared with the Standard & Poor's 500
Index (S&P 500). While the Fund does not seek to match the returns of the S&P
500, this index is a good indicator of general stock market performance. You may
not invest in the S&P 500 and unlike the Fund, it does not incur fees or
charges.

Investment Techniques,
Securities and
Associated Risks


BEFORE YOU INVEST. . .

in any of the Berger Funds, make sure you understand the risks involved. All
investments involve risk. Generally, the greater the risk, the greater the
potential for return. The reverse is also generally true, the lower the risk,
the lower the potential for return.

Like all mutual funds, an investment in the Berger Funds is not a bank deposit
and is not insured or guaranteed by the FDIC or any other government agency. The
Funds are not a complete investment program, but may serve to diversify other
types of investments in your portfolio. There is no guarantee that the Funds
will meet their investment goals, and although you have the potential to make
money, you could also lose money by investing in the Funds.


The table on the opposite page will help you further understand the risks the
Funds take by investing in certain securities and the investment techniques used
by the Berger Funds. A glossary follows the opposite page. You may get more
detailed information about the risks of investing in the Berger Funds in the
Statement of Additional Information (SAI), including a discussion of debt
security ratings in Appendix A to the SAI.


KEY TO TABLE

Follow down the columns under the name of the Fund in which you are interested.
The boxes will tell you:



    Y   Yes, the security or technique is permitted by a Fund and is emphasized
        by a Fund.



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



    <   (Note: Character is a hollow Y) (Yes, the security or technique is
        permitted by a Fund.



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

    N   No, the security or technique is not permitted by a Fund.


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


    F   The restriction is fundamental to a Fund.
        (Fundamental restrictions cannot be changed without a shareholder
        vote.)


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



    5   Use of a security or technique is permitted, but subject to a
        restriction of up to 5% of total assets.

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


Notes to table

1. The Funds have no minimum quality standards for convertible securities,
although they will not invest in defaulted securities. They also will not invest
20% or more of their assets in convertible securities rated below investment
grade or in unrated convertible securities that the advisor considers to be
below investment grade.


2. IPOs constituted a significant portion of the Fund's performance during the
last fiscal year. However, there can be no assurance that IPOs will continue to
have such a significant impact, if the quality or number of available IPOs
diminishes or if the Fund grows in size and IPOs become an insignificant part of
the Fund's total portfolio.

3. The Berger Balanced Fund may invest only in mortgage-backed securities that
are issued or guaranteed by the U.S. Government or its agencies or
instrumentalities, or in privately issued mortgage-backed or asset-backed
securities that are rated AA/Aa (S&P/Moody's) or above.

4. The Funds may use futures, forwards and options only for hedging. Not more
than 5% of a Fund's net assets may be used for initial margins for futures and
premiums for options, although a Fund may have more at risk under these
contracts than the initial margin or premium. However, a Fund's aggregate
obligations under these contracts may not exceed the total market value of the
assets being hedged, such as some or all of the value of the Fund's equity
securities.

Risk and Investment
Glossary


BORROWING refers to a loan of money from a bank or other financial institution
undertaken by a Fund for temporary or emergency reasons only.

CALL RISK is the possibility that an issuer may redeem or "call" a fixed-income
security before maturity at a price below its current market price. An increased
likelihood of a call may reduce the security's price.

COMMON STOCK is a share of ownership (equity) interest in a company.

COMPANIES WITH LIMITED OPERATING HISTORIES are securities issued by companies
that have been in continuous operation for less than three years. Sometimes
called "unseasoned" issuers.

CONVERTIBLE SECURITIES are debt or equity securities which may be converted on
specified terms into stock of the issuer.

CORRELATION RISK occurs when a Fund "hedges" -- uses one investment to offset
the Fund's position in another. If the two investments do not behave in relation
to one another the way Fund managers expect them to, then unexpected results may
occur.

CREDIT RISK means that the issuer of a security or the counterparty to an
investment contract may default or become unable to pay its obligations when
due.

CURRENCY RISK happens when a Fund buys or sells a security denominated in
foreign currency. Foreign currencies "float" in value against the U.S. dollar.
Adverse changes in foreign currency values can cause investment losses when a
Fund's investments are converted to U.S. dollars.

EXTENSION RISK is the risk that, as interest rates rise, borrowers are less
likely to refinance their mortgages or other debts. As a result, the principal
on mortgage-backed or asset-backed securities may be paid later than expected,
which could cause the value of the securities to go down.

DIVERSIFICATION means a diversified fund may not, with respect to at least 75%
of its assets, invest more than 5% in the securities of one company. A
nondiversified fund may be more volatile than a diversified fund because it
invests more of its assets in a smaller number of companies and the gains or
losses on a single stock will therefore have a greater impact on the Fund's
share price. All of the Berger Funds are diversified funds, except the Berger
Select Fund.

FINANCIAL FUTURES are exchange-traded contracts on securities, securities
indexes or foreign currencies that obligate the holder to take or make future
delivery of a specified quantity of those underlying securities or currencies on
a predetermined future date at a predetermined price.

FOREIGN SECURITIES are issued by companies located outside of the United States.
A Fund considers a company to be located outside the United States if the
principal securities trading market for its equity securities is located outside
the U.S. or it is organized under the laws of, and has a principal office in, a
country other than the U.S.

FORWARD FOREIGN CURRENCY CONTRACTS are privately negotiated contracts committing
the holder to purchase or sell a specified quantity of a foreign currency on a
predetermined future date at a predetermined price.

HEDGING RISK comes into play when a Fund uses a security whose value is based on
an underlying security or index to "offset" the Fund's position in another
security or currency. The objective of hedging is to offset potential losses in
one security with gains in the hedge. But a hedge can eliminate or reduce gains
as well as offset losses. (Also see "Correlation risk.")

ILLIQUID AND RESTRICTED SECURITIES are securities which, by rules of their issue
or by their nature, cannot be sold readily. These do not include liquid Rule
144A securities.

INFORMATION RISK means that information about a security or issuer might not be
available, complete, accurate or comparable.

INITIAL PUBLIC OFFERING (IPO) is the sale of a company's securities to the
public for the first time. IPO companies can be small and have limited operating
histories. The price of IPO securities can be highly unstable due to prevailing
market psychology and the small number of shares available. In addition, the
quality and number of IPOs available for purchase may diminish in the future,
and their contribution to Fund performance may be less significant as a Fund
grows in size.

INTEREST RATE RISK is the risk that changes in interest rates will adversely
affect the value of an investor's securities. When interest rates rise, the
value of fixed-income securities will generally fall. Conversely, a drop in
interest rates will generally cause an increase in the value of fixed-income
securities. Longer-term securities are subject to greater interest rate risk.

INVESTMENT GRADE BONDS are rated BBB (Standard & Poor's) or Baa (Moody's) or
above. Bonds rated below investment grade are subject to greater credit risk
than investment grade bonds.

LENDING PORTFOLIO SECURITIES to qualified financial institutions is undertaken
in order to earn income. The Funds lend securities only on a fully
collateralized basis.

                                                                    Berger Funds


LEVERAGE RISK occurs in some securities or techniques that tend to magnify the
effect of small changes in an index or a market. This can result in a loss that
exceeds the amount that was invested in the contract.

LIQUIDITY RISK occurs when investments cannot be sold readily. A Fund may have
to accept a less-than-desirable price to complete the sale of an illiquid
security or may not be able to sell it at all.

MARKET CAPITALIZATION is the total current market value of a company's
outstanding common stock.

MARKET RISK exists in all mutual funds and means the risk that the prices of
securities in a market, a sector, or an industry will fluctuate, and that such
movements might reduce an investment's value.

MORTGAGE-BACKED SECURITIES are securities that represent interests in "pools" of
mortgages or that are backed by mortgages where the interest and principal
payments on the mortgages are "passed-through" to the security holder.
Mortgage-backed securities may be issued or guaranteed by the U.S. Government.
They may also be privately issued and backed by U.S. Government guaranteed
securities or by private arrangements to make them more secure. ASSET-BACKED
SECURITIES are similar, except backed by assets such as car loans or credit card
receivables rather than mortgages.

OPPORTUNITY RISK means missing out on an investment opportunity because the
assets necessary to take advantage of it are committed to less advantageous
investments or strategies.

OPTIONS are contracts giving the holder the right but not the obligation to
purchase or sell a security on or before a predetermined future date at a fixed
price. Options on securities indexes are similar, but settle in cash.

POLITICAL RISK comes into play with investments, particularly foreign
investments, which may be adversely affected by nationalization, taxation, war,
government instability or other economic or political actions or factors.

PREPAYMENT RISK is the risk that, as interest rates fall, borrowers are more
likely to refinance their debts. As a result, the principal on certain
fixed-income securities may be paid earlier than expected, which could cause
investment losses and cause prepaid amounts to have to be reinvested at a
relatively lower interest rate.

SECTOR FOCUS occurs when a significant portion of a Fund's assets are invested
in a relatively small number of related industries. The Funds will not
concentrate more than 25% of their total assets in any one industry. Sector
focus may increase both market and liquidity risk.

SMALL AND MID-SIZED COMPANY SECURITIES are securities issued by small or
mid-sized companies, as measured by their market capitalization. The market
capitalization range targeted by each of the Funds investing primarily in small
or mid-sized companies varies by Fund and appears in the description for those
Funds under the heading "The Fund's Goal and Principal Investment Strategies."
In general, the smaller the company, the greater its risks.

SPECIAL SITUATIONS are companies about to undergo a structural, financial or
management change which may significantly affect the value of their securities.

TEMPORARY DEFENSIVE MEASURES may be taken when a Fund's investment manager
believes they are warranted due to market conditions. When this happens, the
Fund may increase its investment in government securities and other short-term
securities without regard to the Fund's investment restrictions, policies or
normal investment emphasis.

TRANSACTION RISK means that a Fund may be delayed or unable to settle a
transaction or that commissions and settlement expenses may be higher than
usual.

WRITING (SELLING) COVERED CALL OPTIONS is the selling of a contract to another
party which gives them the right but not the obligation to buy a particular
security from you. A Fund will write call options only if it already owns the
security (if it is "covered").

     addresses.

o    Each Fund or CAT Portfolio must be legally eligible for sale in your state
     of residence.

o    You may exchange out of each of the Berger Funds up to four times per
     calendar year. At this time, there is no limit on the number of exchanges
     permitted out of the CAT Portfolios.

o    You may exchange by telephone, online access or mail.

o    You are responsible for obtaining and reading the prospectus for the Fund
     or CAT Portfolio into which you are exchanging.

o    An exchange out of a Berger Fund results in the sale of that Fund's shares
     and the purchase of another, normally resulting in a taxable event for you.

o    Exchanges into any new Fund or CAT Portfolio are subject to that Fund's or
     Portfolio's initial and subsequent investment minimums.

o    The Berger Information Technology Fund will deduct a 1% redemption fee from
     the amount you exchange if you exchange shares of that Fund held less than
     6 months. This fee is intended to discourage investors from short-term
     trading of Fund shares and to offset the cost to the Fund of excess
     brokerage and other costs incurred as a result of such trading. This fee
     will not be charged to retirement plan accounts.

The Funds may terminate or modify the exchange privilege in the future.

Signature Guarantees/Special Documentation

The Funds use Signature Guarantees to protect you and the Funds from possible
fraudulent requests for redeemed shares. Your redemption request must be in
writing and accompanied by a Signature Guarantee if:

o    Your request exceeds $100,000.

o    You request that payment be made to a name other than the one on your
     account registration.

o    You request that payment be mailed to an address which has been changed
     within 30 days of your redemption request or to an address other than the
     one of record.

o    You change or add information relating to your designated bank.

Berger Funds reserve the right to require Signature Guarantees under other
certain circumstances.

You can get a Signature Guarantee from most broker-dealers, national or state
banks, credit unions, federal savings and loan associations or other eligible
institutions. You cannot obtain a Signature Guarantee from a notary public.

Make sure the Signature Guarantee appears:

o    Together with the signature(s) of all registered owner(s) of the redeemed
     shares on the written redemption request.

o    On any share certificates you hold for the redeemed shares or on a separate
     statement of assignment (stock power) which may be obtained from a bank or
     broker.

Additional documents are required for redemptions by corporations, executors,
administrators, trustees and guardians. For instructions, call (800) 551-5849 or
write to the Berger Funds, P.O. Box 219958, Kansas City, MO 64121-9958.

Your Share Price

The price at which you buy, sell or exchange Fund shares is the share price or
net asset value (NAV). The share price for each Fund is determined by adding the
value of that Fund's investments, cash and other assets, deducting liabilities,
and then dividing that value by the total number of that Fund's shares
outstanding. For Funds offering more than one class of shares, share price is
calculated separately for each class.

Each Fund's share price is calculated at the close of the regular trading
session of the New York Stock Exchange (normally 4:00 p.m. New York time) each
day that the Exchange is open. Share price is not calculated on the days that
the Exchange is closed.

For a purchase, redemption or exchange of Fund shares, your price is the share
price next calculated after your request is received in good order and accepted
by the Fund, its authorized agent or designee. To receive a specific day's
price, your request must be received before the close of the New York Stock
Exchange on that day.

When the Funds calculate their share price, they value the securities they hold
at market value. Sometimes market quotes for some securities are not available
or are not representative of market value. Examples would be when events occur
that materially affect the value of a security at a time when the security is
not trading or when the securities are illiquid. In that case, securities may be
valued in good faith at fair value, using consistently applied procedures
decided on by the trustees or directors. Money market instruments maturing
within 60 days are valued at amortized cost, which approximates market value.
Assets and liabilities expressed in foreign currencies are converted into U.S.
dollars at the prevailing market rates quoted by one or more banks or dealers
shortly before the close of the Exchange.

A Fund's foreign securities may trade on days that the Exchange is closed and
the Fund's daily share price is not calculated. As a result, the Fund's daily
share price may be affected and you will not be able to purchase or redeem
shares.

Other Information About Your Account

SECURITY CONSIDERATIONS

You may give up some level of security by choosing to buy or sell shares by
telephone or online, rather than by mail. The Funds use procedures designed to
give reasonable assurance that telephone and online instructions are genuine,
including recording the transactions, testing the identity of the shareholder
placing the order and sending prompt written confirmation of transactions to the
shareholder of record. The Funds, and their service providers, are not liable
for acting upon instructions communicated by telephone or online that they
believe to be genuine if these procedures are followed.

CONFIRMATION OF YOUR PURCHASES AND REDEMPTIONS

After any transaction, you will receive written confirmation including the share
price and the dollar amount and number of shares bought or redeemed. Exception:
Shares purchased under Systematic Investment Plans or redeemed under Systematic
Withdrawal Plans will be confirmed quarterly. Partial shares will be calculated
to three decimal places.

SHAREHOLDER REPORTS

To reduce expenses, a Fund may mail only one copy of most financial reports,
prospectuses and proxies to your household, even if you have more than one
account in the Fund. Call (800) 551-5849 if you need additional copies of
financial reports or prospectuses.

SHARE CERTIFICATES

To assist in minimizing administrative costs, share certificates will not be
issued. Records of share ownership are maintained by the Fund's transfer agent
in book entry form. If you are selling shares previously issued in certificate
form, you need to include the certificate along with your redemption or exchange
request. If you have lost your certificate, please call us at (800) 551-5849.

PURCHASES THROUGH BROKER-DEALERS

You may buy Fund shares through certain broker-dealers or other financial
organizations, but these organizations may charge you a fee or may have
different minimums for first-time or additional investments which are not
applicable if you buy shares directly from the Funds.

Information About
Your Account
(continued)


THIRD PARTY ADMINISTRATORS

Certain brokerage firms and other companies may provide administrative services
(such as sub-transfer agency, recordkeeping or shareholder communications
services) to investors purchasing shares of the Funds through those 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.

DATE-RELATED INFORMATION

Mutual funds and businesses around the world could be adversely affected if
computers do not properly process date-related information. The Funds' advisors
are addressing these issues for their computers and are getting reasonable
assurances from the Funds' other major service providers that they too are
addressing these issues to preserve smooth functioning of the Funds' trading,
pricing, shareholder account, custodial and other operations. There can be no
assurances, however, that all problems will be avoided.

These computer problems could also adversely affect the Funds' investments.
Improperly functioning computers may disrupt securities markets generally or
result in overall economic uncertainty. Individual companies may also be
adversely affected by the cost of fixing their computers, which could be
substantial. The Funds' investment managers consider these issues when
evaluating investments for the Funds.

REDEMPTIONS IN-KIND

Each Fund intends to redeem its shares only for cash, although in order to
protect the interest of remaining shareholders, it retains the right to redeem
its shares in-kind under unusual circumstances. In-kind payment means payment
will be made to you in portfolio securities rather than cash. If this occurs,
you will incur transaction costs if you sell the securities for cash. You may
have difficulty selling the securities and recovering the amount of your
redemption if the securities are illiquid.

ACCOUNT MINIMUMS

The Funds will charge all shareholder accounts with a balance of less than
$2,000 an annual fee of $10 unless the shareholder account is making automatic
monthly investments. This charge is designed to help offset the proportionately
higher costs of maintaining small accounts.

This charge will apply to accounts that have been over $2,000 at some point in
time only if the balance has dropped below this amount because shares were
redeemed, not because the share value declined.

Shares in accounts that do not meet the minimum balance requirement applicable
to them as described below may also be subject to involuntary redemption by the
Funds.

REDEMPTIONS BY THE FUNDS OF CERTAIN ACCOUNTS

To reduce their expenses, all Funds other than the Berger Growth Fund may
involuntarily redeem the shares in your account if your balance drops below
$2,000 - but only if it drops below this amount because you have redeemed
shares, not because the share value has declined. You will be given 60 days'
notice before a Fund undertakes any involuntary redemption. During that time,
you may buy more shares to bring your account above the minimum. Existing
shareholders of the following Funds have lower minimum balance requirements and
must maintain these minimum balances to avoid involuntary redemption:

Distributions and Taxes

DISTRIBUTIONS OF INCOME AND GAINS

Unless you tell us that you want to receive your distributions in cash, they
will be reinvested automatically in Fund shares. The Funds generally make two
different kinds of distributions:

o    Capital gains from the sale of portfolio securities held by a fund. Each
     Fund will distribute any net realized capital gains annually, normally in
     December.

o    Net investment income from interest or dividends received on securities
     held by a fund. The Funds will distribute their investment income as
     follows:

                                   (normally in December)
</TABLE>

YOUR TAXES

You generally will owe tax on amounts distributed to you by the Funds in any
non-retirement account whether you reinvest them in additional shares or receive
them in cash. Distributions of gains from the sale of assets held by a Fund for
more than one year generally are taxable to you at the applicable long-term
capital gains rate, regardless of how long you have owned your Fund shares.
Distributions from other sources generally are taxed as ordinary income.

Distributions made by the Funds to you will normally be capital gains. A portion
of those gains may be net short-term capital gains, which are taxed as ordinary
income. The Berger Growth and Income Fund and the Berger Balanced Fund normally
will also distribute net investment income, which is taxed as ordinary income.
The other Berger Funds generally will not distribute net investment income,
although any net investment income that is generated as a by-product of managing
their portfolios will be distributed to you.

If you redeem Fund shares that have appreciated in value, you will have a
taxable gain upon redemption. Exchanges are treated as a redemption and purchase
for tax purposes. Therefore, you will also have a taxable gain if you exchange
shares that have appreciated in value.

ADDITIONAL TAX INFORMATION

You should consult your own tax advisor about your particular situation. For
more information about other tax matters, including backup withholding for
certain taxpayers and other tax aspects of redemptions, see the SAI.

Tax-Sheltered Retirement Plans

The Funds offer several tax-qualified retirement plans for individuals,
businesses and nonprofit organizations. For information about establishing an
IRA, Roth IRA, profit-sharing or money purchase pension plan, 403(b) Custodial
Account, SEP-IRA, SIMPLE IRA account or other retirement plans, please call
(800) 551-5849 or write to the Berger Funds, P.O. Box 219958, Kansas City, MO
64121-9958. Trustees for existing 401(k) or other plans interested in using Fund
shares as an investment or investment alternative in their plans are invited to
call the Funds at (800) 259-2820.

PORTFOLIO TURNOVER

Portfolio changes are made whenever the Fund's investment manager believes that
the Fund's goal could be better achieved by investment in another security,
regardless of portfolio turnover. At times, portfolio turnover for a Fund may
exceed 100% per year. A turnover rate of 100% means the securities owned by a
Fund were replaced once during the year. Higher turnover rates may result in
higher brokerage costs to the Funds and in higher net taxable gains for you as
an investor. Each Fund's portfolio turnover rate can be found under the heading
"Financial Highlights for the Berger Funds Family."

12b-1 Arrangements

The Funds are "no-load" funds, meaning that you pay no sales charge or
commissions when you buy or sell Fund shares. However, each Fund has adopted a
12b-1 plan permitting it to pay a fee in connection with distribution of its
shares. Berger LLC is entitled to be paid a fee under each plan of 0.25% of each
Fund's average daily net assets. Because this fee is paid on an ongoing basis,
this may result in the cost of your investment increasing and over time may cost
you more than other types of sales charges. The fee may be used for such things
as marketing and promotion, compensation to dealers and others who provide
distribution and administrative services, and shareholder support services (such
as routine requests for information).

Special Fund Structures

MULTI-CLASS


The Berger Information Technology Fund, the Berger New Generation Fund and the
Berger Small Company Growth Fund each currently has two classes of shares. The
Investor Shares offered in this prospectus are available to the general public.
The other class of shares, Institutional Shares, are offered through a separate
prospectus and are designed for investors who maintain a minimum account balance
of $250,000. Each class of shares has its own expenses so that share price,
performance and distributions will differ between classes. The 12b-1 plans
adopted by these Funds apply only to the Investor Shares. For more information
on Institutional Shares, please call (800) 259-2820.


MASTER/FEEDER


The Berger International Fund is organized as a "feeder" fund in a
"master/feeder" structure. This means that the Fund's assets are all invested in
a larger "master" portfolio of securities, the Berger International Portfolio,
which has investment goals and policies identical to those of the Fund. The
other feeders investing in the Portfolio are the International Equity Fund and
the Berger International CORE Fund, each of which has a minimum balance
requirement of $1,000,000 and its own expenses so that share price, performance
and distributions will differ among feeders. For more information on these
feeders, please call (800) 259-2820.


The Fund may withdraw its investment in the Portfolio at any time, if the
Trustees determine that it is in the best interests of the Fund to do so. In
that event, the Fund might transfer to another master fund or hire its own
investment advisor. A withdrawal could result in the Fund receiving an in-kind
distribution of portfolio securities from the Portfolio. In that case, the Fund
could incur brokerage, tax or other charges if it converted the securities to
cash. In addition, an in-kind distribution could adversely affect the liquidity
of the Fund.

For more information on multi-class and master/feeder fund structures, see the
SAI.

The following financial highlights are for the Fund for periods ending February
28, 1998 and 1999, and for the period from March 1, 1999 to July 1, 1999, prior
to the Fund's reorganization. Prior to the Fund's reorganization on July 2,
1999, the Fund was known as the InformationTech 100(R) Fund. At the time of the
reorganization, the Fund adopted share classes and first began offering the
Investor Shares. Therefore, the 0.25% 12b-1 fee paid by the Investor Shares is
not reflected in the data on the table. Unless otherwise noted, this information
was audited by the Fund's prior independent accountants. Their report appears in
the 1999 Annual Report to Shareholders of the InformationTech 100(R) Fund and is
available from the Fund without charge upon request. The information for the
period March 1, 1999 to July 1, 1999 is unaudited.

                                                            Financial Highlights



The following table is based on the historical financial statements of the pool
of assets that was, in a practical sense, the predecessor to the Portfolio in
which the Berger International Fund is invested. The total return, expense
ratios and per share data on the table have been adjusted to reflect the
increase in Fund operating expenses that was expected to occur when the pool's
assets were transferred to the Portfolio over the pool's actual operating
expenses for each period shown.


The table covers the period from the beginning of the pool through October 11,
1996, when the pool's assets were transferred to the Portfolio. The pool was not
registered with the SEC and was not subject to the investment restrictions
imposed on mutual funds. If the pool had been registered, the pool's financial
results might have been adversely affected.

                                  INTRODUCTION

                  The Funds described in this SAI are all mutual funds, or
open-end, management investment companies. All of the Funds are diversified
funds, except the Berger Select Fund. See below under "Non-Diversification" in
Section 1 for further information concerning the Berger Select Fund. 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.                INVESTMENT STRATEGIES AND RISKS OF THE FUNDS

                  The Prospectus describes the investment objective of each of
the Funds and the principal investment policies and strategies used to achieve
that objective. It also describes the principal risks of investing in each Fund.


                  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 International Fund, the term "Fund" in this Section 1 should be read to
mean the Berger 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 volatile than
shorter-term securities, but they generally offer higher yields to compensate
investors for the associated risks.

                  Certain debt securities can also present prepayment risk. For
example, a security may contain redemption and call provisions. If an issuer
exercises these provisions when interest rates are declining, the Fund could
sustain investment losses as well as have to reinvest the proceeds from the
security at lower interest rates, resulting in a decreased return for the Fund.


                                      -1-
<PAGE>   53

                  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. Each of the Funds, except the Berger New
Generation Fund, the Berger Small Company Growth Fund and the Berger
International Fund, 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.


                  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 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.

                  INITIAL PUBLIC OFFERINGS. The Funds may invest in a company's
securities at the time the company first offers securities to the public, that
is, at the time of the company's initial public offering or IPO. Although
companies can be any age or size at the time of their IPOs, they are often
smaller and have a limited operating history, which involve a greater potential
for the value of their securities to be impaired following the IPO. See
"Securities of Smaller Companies" and "Securities of Companies with Limited
Operating Histories" above.

                                      -2-
<PAGE>   54

                  Investors in IPOs can be adversely affected by substantial
dilution in the value of their shares, by sales of additional shares and by
concentration of control in existing management and principal shareholders. In
addition, all of the factors that affect stock market performance may have a
greater impact on the shares of IPO companies.

                  The price of a company's securities may be highly unstable at
the time of its IPO and for a period thereafter due to market psychology
prevailing at the time of the IPO, the absence of a prior public market, the
small number of shares available and limited availability of investor
information. As a result of this or other factors, a Fund's advisor or
sub-advisor might decide to sell an IPO security more quickly than it would
otherwise, which may result in a significant gain or loss and greater
transaction costs to the Fund. Any gains from shares held for 12 months or less
will be treated as short-term gains, taxable as ordinary income to the Fund's
shareholders. In addition, IPO securities may be subject to varying patterns of
trading volume and may, at times, be difficult to sell without an unfavorable
impact on prevailing prices.

                  The effect of an IPO investment can have a magnified impact on
a Fund's performance when the Fund's asset base is small. Consequently, IPOs may
constitute a significant portion of a Fund's returns particularly when the Fund
is small. Since the number of securities issued in an IPO is limited, it is
likely that IPO securities will represent a smaller component of a Fund's assets
as it increases in size, and therefore have a more limited effect on the Fund's
performance.

                  There can be no assurance that IPOs will continue to be
available for any of the Funds to purchase. The number or quality of IPOs
available for purchase by a Fund may vary, decrease or entirely disappear. In
some cases, a Fund may not be able to purchase IPOs at the offering price, but
may have to purchase the shares in the aftermarket at a price greatly exceeding
the offering price, making it more difficult for the Fund to realize a profit.

                  The advisor's or sub-advisor's IPO trade allocation procedures
govern which Funds and other advised accounts participate in the allocation of
any IPO. See the heading "Trade Allocations" under Section 4 below. Under the
IPO allocation procedures of Berger LLC, a Fund generally will not participate
in an IPO if the securities available for allocation to the Fund are
insignificant relative to the Fund's net assets. As a result, any Fund or
account whose assets are very large (such as the Berger Growth Fund) is not
likely to participate in the allocation of many IPOs.

                  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


                                      -3-
<PAGE>   55

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 companies considered Passive Foreign
Investment Companies (PFICs) under U.S. tax laws. For certain types of PFICs, 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 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. 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

                                      -4-
<PAGE>   56

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 net 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 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. Each of the Funds, except the
Berger Growth Fund and the Berger Growth and Income Fund, 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, a Fund 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 Fund permitted to lend its portfolio securities may lend
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 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.

                  A Fund lending securities bears 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
(including the value of the collateral received to secure the loan). 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.

                  Although voting rights with respect to loaned securities pass
to the borrower, lending Funds retain the right to recall a security (or
terminate a loan) for the purpose of exercising the security's voting rights.
Efforts to recall loaned securities in time to exercise voting rights may be
unsuccessful, especially for foreign securities or thinly traded securities. In
addition, it is expected that loaned securities will be recalled for voting only
when the items being voted on are, in the judgment of the lending Fund's
advisor, either material to the economic value of the security or threaten to
materially impact the issuing company's corporate governance policies or
structure.


                  SHORT SALES. Each Fund (other than the Berger International
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"). The Berger International Fund is not permitted to engage in
short sales at all.


                  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.

                  In the past, 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, federal tax
legislation has since 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." Special situations are companies that have recently experienced or
are anticipated to experience a significant change in structure, management,
products or services which may significantly affect the value of their
securities. Examples of special situations are companies being reorganized or
merged, companies emerging from bankruptcy, companies introducing unusual new
products or which enjoy particular tax advantages. Other examples are companies
experiencing changes in senior management, extraordinary corporate events,
significant changes in cost or capital structure or which are believed to 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
companies and their circumstances. By its nature, a "special situation" company
involves to some degree a break with the company's past experience. This creates
greater uncertainty and potential risk of loss than if the company were
operating according to long-established patterns. In addition, stocks of
companies in special situations may decline or not appreciate as expected if an
anticipated change or development does not occur or is not assessed by the
market as favorably as expected.

                  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
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. In addition,
none of the Funds is required to hedge. Decisions regarding hedging are subject
to the advisor's or sub-advisor's judgment of the cost of the hedge, its
potential effectiveness and other factors the advisor or sub-advisor considers
pertinent.

                  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 Information Technology Fund, the Berger
New Generation Fund, the Berger Select Fund, the Berger Small Company Growth
Fund, the Berger Mid Cap Growth Fund, the Berger Mid Cap Value Fund, the Berger
Growth 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 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.


                  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


                                      -7-
<PAGE>   59

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 this 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 will 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 will be available to the Fund
immediately upon closing out the futures position.

                  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


                                      -8-
<PAGE>   60

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 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.

                                      -9-
<PAGE>   61

                  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.

                  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").

                                      -10-
<PAGE>   62

                  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. 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.


                                      -11-
<PAGE>   63

                  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
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


                                      -12-

<PAGE>   64

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.

                  MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The Berger
Balanced Fund may invest in certain mortgage-backed and asset-backed securities.
Mortgage-backed securities are securities that directly or indirectly represent
a participation in, or are secured by and payable from, mortgage loans secured
by real property. Asset-backed securities are similar, except that they are
backed by assets other than mortgages, such as motor vehicle installment sales
contracts, installment loan contracts, leases of various types of real and
personal property and receivables from revolving credit agreements (credit
cards).

                  The primary risk of any mortgage-backed or asset-backed
security is the uncertainty of the timing of cash flows from the assets
underlying the securities. See the subheading "Special Risks of Mortgage-Backed
Securities" below for more information about prepayment and extension risks.
Also, see the subheading "Asset-Backed Securities" below for more information
about asset-backed securities.

                  There are currently three basic types of mortgage-backed
securities: (i) those issued or guaranteed by the United States Government or
one of its agencies or instrumentalities, such as the Government National
Mortgage Association (GNMA), the Federal National Mortgage Association (FNMA)
and the Federal Home Loan Mortgage Corporation (FHLMC); (ii) those issued by
private issuers that represent an interest in or are collateralized by
mortgage-backed securities issued or guaranteed by the United States Government
or one of its agencies or instrumentalities; and (iii) those issued by private
issuers that represent an interest in or are collateralized by whole mortgage
loans or mortgage-backed securities without a government guarantee but usually
having some form of private credit enhancement.

                  U.S. Government Mortgage-Backed Securities. The Fund may
invest in mortgage-backed securities issued or guaranteed by GNMA, FNMA and
FHLMC. GNMA certificates are backed by the "full faith and credit" of the United
States. FNMA and FHLMC certificates are not backed by the full faith and credit
of the United States, but the issuing agency or instrumentality has the right to
borrow, to meet its obligations, from an existing line of credit with the U.S.
Treasury. The U.S. Treasury has no legal obligation to provide such line of
credit and may choose not to do so. Each of GNMA, FNMA and FHLMC guarantee
timely distribution of interest to certificate holders. GNMA and FNMA also
guarantee timely distribution of scheduled principal payments. FHLMC generally
guarantees only the ultimate collection of principal of the underlying mortgage
loans.

                  Collateralized Mortgage Obligations and Multiclass
Pass-Through Securities. The Berger Balanced Fund may also invest in
collateralized mortgage obligations (CMOs). CMOs are debt obligations
collateralized by mortgage loans or mortgage pass-through securities. Typically,
CMOs are collateralized by GNMA, FNMA or FHLMC certificates, but also may be
collateralized by whole loans or private mortgage pass-through securities (such
collateral is referred to in this section as Mortgage Assets). Multiclass
pass-through securities are equity interests in a trust composed of Mortgage
Assets. Payments of principal of and interest on the Mortgage Assets, and any
reinvestment income thereon, provide the funds to pay debt service on the CMOs
or make scheduled distributions on the multiclass pass-through securities. CMOs
may be issued by agencies or instrumentalities of the U. S. Government, or by
private originators of, or investors in, mortgage loans, including savings and
loan associations, mortgage banks, commercial banks, investment banks and
special purpose subsidiaries of the foregoing. The Fund may invest in CMOs
issued by private entities only if the CMOs are rated at least investment grade
(at least BBB by S&P or Baa by Moody's) or, if unrated, are determined to be of
comparable quality.

                  In a CMO, a series of bonds or certificates is issued in
multiple classes. Each class of CMOs, often referred to as a "tranche," is
issued at a specific fixed or floating coupon rate and has a stated maturity or
final distribution date. Interest is paid or accrues on all classes of the CMOs
on a monthly, quarterly or semiannual basis. Certain CMOs may have variable or
floating interest rates. The principal of and interest on the Mortgage Assets
may be allocated among the several classes of a CMO series in a number of
different ways.

                  Generally, the purpose of the allocation of the cash flow of a
CMO to the various classes is to obtain a more predictable cash flow to the
individual tranches than exists with the underlying collateral of the CMO. As a
general rule, the more predictable the cash flow is on a CMO tranche, the lower
the anticipated yield will be on that tranche at the time of issuance relative
to prevailing market yields on mortgage-backed securities. As part of the
process of creating more predictable cash flows on most of the tranches in a
series of CMOs, one or more tranches generally must be created that


                                      -13-

<PAGE>   65

absorb most of the volatility in the cash flows on the underlying mortgage
loans. The yields on these tranches may be higher than prevailing market yields
on mortgage-backed securities with similar maturities. As a result of the
uncertainty of the cash flows of these tranches, the market prices of and yield
on these tranches generally are more volatile.

                  The Fund also may invest in parallel pay CMOs and Planned
Amortization Class CMOs (PAC Bonds). Parallel pay CMOs are structured to provide
payments of principal on each payment date to more than one class. These
simultaneous payments are taken into account in calculating the stated maturity
date or final distribution date of each class, which, as with other CMO
structures, must be retired by its stated maturity date or final distribution
date but may be retired earlier. PAC Bonds generally require payments of a
specified amount of principal on each payment date. PAC Bonds always are
parallel pay CMOs with the required principal payment on such securities having
the highest priority after interest has been paid to all classes.

                  The Fund may not invest in "stripped" mortgage-backed
securities (interest-only securities (IOs) or principal-only securities (POs))
or in mortgage-backed securities known as "inverse floaters."

                  Adjustable Rate Mortgages. The Berger Balanced Fund may also
invest in adjustable rate mortgage securities (ARMs), which are pass-through
mortgage securities collateralized by mortgages with adjustable rather than
fixed rates. ARMs, like fixed rate mortgages, have a specified maturity date,
and the principal amount of the mortgage is repaid over the life of the
mortgage. Unlike fixed rate mortgages, the interest rate on ARMs is adjusted at
regular intervals based on a specified, published interest rate "index" such as
a Treasury rate index. The new rate is determined by adding a specific interest
amount, the "margin," to the interest rate of the index. Investment in ARM
securities allows the Fund to participate in changing interest rate levels
through regular adjustments in the coupons of the underlying mortgages,
resulting in more variable current income and lower price volatility than
longer-term fixed rate mortgage securities. ARM securities are a less effective
means of locking in long-term rates than fixed rate mortgages since the income
from adjustable rate mortgages will increase during periods of rising interest
rates and decline during periods of falling rates.

                  Private Mortgage Pass-Through Securities. Private mortgage
pass-through securities are structured similarly to the GNMA, FNMA and FHLMC
mortgage pass-through securities and are issued by originators of and investors
in mortgage loans, including depository institutions, mortgage banks, investment
banks and special purpose subsidiaries of the foregoing. These securities
usually are backed by a pool of conventional fixed rate or adjustable rate
mortgage loans. Since private mortgage pass-through securities typically are not
guaranteed by an entity having the credit status of GNMA, FNMA and FHLMC, these
securities generally are structured with one or more types of credit enhancement
to make them more secure, which may be through guarantees, insurance policies or
letters of credit obtained by the issuer or sponsor from third parties, through
various means of structuring the transaction or through a combination of those
approaches. The Fund may invest in private mortgage pass-through securities only
if they are rated AA/Aa (S&P/Moody's) or above.

                  Special Risks of Mortgage-Backed Securities. Mortgage-backed
securities have certain different characteristics than traditional debt
securities. As a result of the risks associated with these securities, the Fund
could realize a loss by investing in them, regardless of their rating or their
credit enhancement features.

                  Among the major differences between mortgage-backed securities
and traditional debt securities are that on mortgage-backed securities, interest
and principal payments are made more frequently, usually monthly, and principal
may be prepaid at any time because the underlying mortgage loans or other assets
generally may be prepaid at any time, usually without penalty. Changes in the
rate of prepayments will generally affect the yield to maturity of the security.
Moreover, when the holder of the security attempts to reinvest prepayments of
principal and interest, it may receive a rate of interest which is higher or
lower than the rate on the mortgage-backed securities originally held. To the
extent that mortgage-backed securities are purchased at a premium, mortgage
foreclosures and principal prepayments may result in a loss to the extent of the
premium paid. If such securities are bought at a discount, both scheduled
payments of principal and unscheduled prepayments will increase current and
total returns and will accelerate the recognition of income which, when
distributed to shareholders, will be taxable as ordinary income.

                  Mortgage-backed securities, like all fixed-income securities,
generally decrease in value as a result of increases in interest rates. In
addition, although generally the value of fixed-income securities increases
during periods of falling interest rates and decreases during periods of rising
interest rates, as a result of prepayments and other factors, this is not always
the case with respect to mortgage-backed securities.

                                      -14-

<PAGE>   66

                  Although the extent of prepayments on a pool of mortgage loans
depends on various economic and other factors, as a general rule, prepayments on
fixed rate mortgage loans will increase during a period of falling interest
rates and decrease during a period of rising interest rates. Accordingly, during
a period of declining rates, the Fund is likely to have greater amounts to
reinvest as a result of prepayments and is likely to have to reinvest those
amounts at lower interest rates than during a period of rising interest rates.
Mortgage-backed securities generally decrease in value as a result of increases
in interest rates and may benefit less than other fixed-income securities from
declining interest rates because of the risk of prepayment.

                  The Fund may invest in mortgage derivative securities, such as
CMOs, the average life of which is determined using mathematical models that
incorporate prepayment assumptions and other factors that involve estimates of
future economic and market conditions. These estimates may vary from actual
future results, particularly during periods of extreme market volatility. In
addition, under certain market conditions, the average weighted life of mortgage
derivative securities may not accurately reflect the price volatility of such
securities. For example, in periods of supply and demand imbalances in the
market for such securities and/or in periods of sharp interest rate movements,
the prices of mortgage derivative securities may fluctuate to a greater extent
than would be expected from interest rate movements alone.

                  The Fund's investments in mortgage derivative securities also
subject the Fund to extension risk. Extension risk is the possibility that
rising interest rates may cause prepayments to occur at a slower than expected
rate. This particular risk may effectively change a security which was
considered short or intermediate-term at the time of purchase into a long-term
security. Long-term securities generally fluctuate more widely in response to
changes in interest rates than short or intermediate-term securities.

                  In addition, CMOs and other mortgage-backed securities issued
by private entities are not U.S. government securities and are not guaranteed by
any government agency, although the pool of securities underlying a privately
issued mortgage-backed security may be subject to a guarantee. Therefore, if the
collateral securing a privately issued mortgage-backed security held by the
Fund, in addition to any third party credit support or guarantees, is
insufficient to make payment, the Fund could sustain a loss on its investment in
that security. However, as stated above, the Fund will invest in CMOs and other
mortgage-backed securities issued by private entities only if they are rated
AA/Aa (S&P/Moody's) or above.



                  Asset-Backed Securities. The Berger Balanced Fund may also
invest in asset-backed securities. Asset-backed securities are securities that
represent direct or indirect participation in, or are secured by and payable
from, assets other than mortgage-backed assets, such as motor vehicle
installment sales contracts, installment loan contracts, leases of various types
of real and personal property and receivables from revolving credit agreements
(credit cards). Asset-backed securities have yield characteristics similar to
those of mortgage-backed securities and are subject to many of the same risks.
See the subheading "Special Risks of Mortgage-Backed Securities" above for a
discussion of those risks. In addition, asset-backed securities involve certain
risks that are not posed by mortgage-backed securities, since asset-backed
securities do not usually contain the complete benefit of a security interest in
the related collateral. For example, credit card receivables generally are
unsecured and the debtors are entitled to the protection of a number of state
and federal consumer credit laws, including the bankruptcy laws, some of which
may reduce the ability to obtain full payment. In the case of automobile
receivables, due to various legal and economic factors, proceeds for repossessed
collateral may not always be sufficient to support payments on these securities.

                  New instruments and variations of existing mortgage-backed
securities and asset-backed securities continue to be developed. The Fund may
invest in any such instruments or variations as may be developed, to the extent
consistent with its investment objective and policies and applicable legal
requirements.


                  TEMPORARY DEFENSIVE MEASURES. Each of the Funds (except the
Berger Information Technology Fund and the Berger 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



                                      -15-

<PAGE>   67

conditions. When in a defensive position, a Fund could miss the opportunity to
participate in any stock or bond market advances that occur during those
periods, which the Fund might have been able to participate in if it had
remained more fully invested.

                  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 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.

                  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.

                  The variation in the portfolio turnover rate for the Berger
Select Fund's two most recently completed fiscal years is due to the increased
size of the Fund and a portfolio manager change.

2.                INVESTMENT RESTRICTIONS

                  As indicated in the Prospectus, the investment objective of
each of the Funds is as follows:

                  The investment objective of the Berger Information Technology
Fund, the Berger New Generation Fund, the Berger Select Fund, the Berger Small
Company Growth Fund, the Berger Mid Cap Growth Fund, the Berger Mid Cap Value
Fund, the Berger Growth Fund, the Berger 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

                  Each Fund has also adopted certain investment policies,
strategies, guidelines and procedures in pursuing its objective. These may be
changed without a shareholder vote. The principal policies and strategies used
by the Funds are described in the Prospectus.

                  In addition, each Fund has adopted certain fundamental and
non-fundamental restrictions on its investments and other activities, which are
listed below. 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 INFORMATION TECHNOLOGY FUND, BERGER NEW GENERATION FUND, BERGER SELECT
FUND, BERGER SMALL COMPANY GROWTH FUND(R), BERGER MID CAP GROWTH FUND, THE
BERGER MID CAP VALUE FUND AND BERGER BALANCED FUND


                  Except as noted, the following fundamental restrictions apply
to each of the Berger Information Technology Fund, the Berger New Generation
Fund, the Berger Select Fund, the Berger Small Company Growth Fund, the Berger
Mid Cap Growth Fund, the Berger Mid Cap Value 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.

                  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 Information Technology Fund, the Berger
New Generation Fund, the Berger Select Fund, the Berger Small Company Growth
Fund, the Berger Mid Cap Growth Fund, the Berger Mid Cap Value 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:

<PAGE>   70

                  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.

                  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.

the value of the holdings of the Fund in the securities of such issuer exceeds

the outstanding voting securities or of any class of securities of such issuer.

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

to exceed 5% of the value of the Fund's total assets.

                  3. Invest in any one industry more than 25% of the value of
its total assets at the time of such investment.

                  4. Make loans, except that the Fund may enter into repurchase

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.

                  5. Borrow in excess of 5% of the value of its total assets, or
pledge, mortgage, or hypothecate its assets taken at market value to an extent
greater than 10% of the Fund's total assets taken at cost (and no borrowing may
be undertaken except from banks as a temporary measure for extraordinary or
emergency purposes). This limitation shall not prohibit or restrict short sales
or deposits of assets to margin or guarantee positions in futures, options or
forward contracts, or the segregation of assets in connection with any of such
transactions.

                  6. Purchase or retain the securities of any issuer if those
officers and directors of the Fund or its investment advisor owning individually

of the securities of such issuer.

                  7. 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).

                  8. 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) or invest in real estate (although it may purchase shares of a
real estate investment trust), or invest in commodities or commodity contracts
except, only for the purpose of hedging, (i) financial futures transactions,
including futures contracts on securities, securities indices and foreign
currencies, and options on any such futures, (ii) forward foreign currency
exchange contracts and other forward commitments and (iii) securities index put
or call options.

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

                  10. Invest in companies for the purposes of exercising control

                  In applying the industry concentration investment restriction
(no. 3 above), the Funds use the industry groups used in the Data Monitor

implementing that


                                      -20-

<PAGE>   72

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 Growth 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 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 International Fund and the Berger 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:

                  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.

                                      -21-

<PAGE>   73

                  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).

                  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.

rate, calculated as a percentage of the average daily net assets of the Fund.

</TABLE>

(1)  Fund is sub-advised by Bay Isle. See text preceding and following table.
     Under a written contract, the Fund's investment advisor waives its fee or
     reimburses the Fund for expenses to the extent that, at any time during the
     life of the Fund, the annual operating expenses for the Investor Shares
     class of the Fund in any fiscal year, including the investment advisory fee
     and the 12b-1 fee, but excluding brokerage commissions, interest, taxes and
     extraordinary expenses, exceed 2.00% of the Fund's average daily net assets
     attributable to the Investor Shares for that fiscal year. The contract also
     provides that the advisor will waive an additional amount of its fees or
     reimburse an additional amount of expenses to the extent necessary to keep
     its fee waiver and reimbursement for the Investor Shares class
     proportionate to its fee waiver and reimbursement for the Fund's other
     outstanding share class. The contract may not be terminated or amended
     except by a vote of the Fund's Board of Trustees. The investment advisory
     fee is allocated among the Investor Shares and the other class of the Fund
     on the basis of net assets attributable to each such class.

(2)  Under a written contract, the Fund's investment advisor waives its fee to
     the extent that, at any time during the life of the Fund, the Fund's annual
     operating expenses (or, if applicable, for the Investor Shares class of the
     Fund) in any fiscal year, including the investment advisory fee and the
     12b-1 fee, but excluding brokerage commissions, interest, taxes and
     extraordinary expenses, exceed 1.90% in the case of the Investor Shares
     class of the Berger New Generation Fund, 2.00% in the case of the Berger
     Mid Cap Growth Fund, and 1.50% in the case of the Berger Balanced Fund, of
     the average daily net assets of the Fund (or applicable class) for that
     fiscal year. The advisor's contract with the Berger Mid Cap Growth Fund and
     the Berger Balanced Fund may not be terminated or amended except by a vote
     of the Fund's Board of Trustees. The agreement with the Berger New
     Generation Fund may be terminated by the advisor upon 90 days' prior
     written notice to the Fund. For the Berger New Generation Fund, the
     investment advisory fee is allocated among the Investor Shares and the
     other class of the Fund on the basis of net assets attributable to each
     such class.

(3)  Under a written agreement, the Fund's investment advisor waives its fee to
     the extent that the annual operating expenses for the Investor Shares class
     of the Fund in any fiscal year, including the investment advisory 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 attributable to the
     Investor Shares for that fiscal year. The agreement may be terminated by
     the advisor upon 90 days' prior written notice to the Fund. The investment
     advisory fee is allocated among the Investor Shares and the other class of
     the Fund on the basis of net assets attributable to each such class.

(4)  Fund is sub-advised by PWM. See text preceding and following table.


(5)  The Berger International Fund bears its pro rata portion of the fee paid by
     the Berger International Portfolio to Berger LLC as the advisor. The
     Portfolio is sub-advised by BIAM. See text preceding and following table.
     Under a written contract, the Portfolio's investment advisor waives its
     investment advisory fee to the extent that, at any time during the life of
     the Portfolio, the Portfolio's annual 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. The contract may not be terminated or amended except by a vote
     of the Portfolio's Board of Trustees. Any such 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 International Fund.

                  Effective May 12, 2000, the investment advisory fee charged to
the Berger International Fund was reduced to the following schedule:

</TABLE>



                  Each Fund's current Investment Advisory Agreement will
continue in effect until the last day of April 2001, 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 advisors and the
sub-advisors for the Berger International Portfolio, the Berger Mid Cap Value
Fund and the Berger Information Technology 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. Each Sub-Advisory Agreement provides that the sub-advisor shall
not be liable for any error of judgment or mistake of law or for any loss
arising out of any investment or for any act or omission taken with respect to
the Fund, except for willful misfeasance, bad faith or gross negligence in the
performance of its duties, or by reason of reckless disregard of its obligations
and duties thereunder and except to the extent otherwise provided by law.



                  No fees are paid directly to the sub-advisors by the Funds. As
the sub-advisor of the Berger Mid Cap Value Fund, PWM receives from the advisor
a fee at the annual rate of 0.375% of the first $500 million of average daily
net assets of the Fund, 0.35% of the next $500 million and 0.325% of any amount
in excess of $1 billion. BIAM, as the sub-advisor of the Berger 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


                                      -32-
<PAGE>   84


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. Bay Isle, as
the sub-advisor of the Berger Information Technology Fund, receives from the
advisor a fee at the annual rate of 0.425% for the first $500 million of the
Fund's average daily net assets of the Fund, 0.40% of he next $500 million and
0.375% of any amount in excess of $1 billion.



                  The Sub-Advisory Agreements will continue in effect until
April 2001 or 2002, 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 LLC AND BAY ISLE

                  Berger LLC and Bay Isle have formed a joint venture to provide
asset management services to certain private accounts. In connection with the
formation of that joint venture, Berger LLC purchased from Bay Isle owners
William F. K. Schaff and Gary G. Pollock the right that, if either Mr. Schaff or
Mr. Pollock ever desires to sell any of his Bay Isle shares in the future, they
will together first offer to sell shares to Berger LLC aggregating at least 80%
of the total outstanding shares of Bay Isle at an agreed price. If Berger LLC
elects to purchase the Bay Isle shares offered, the parties have agreed to use
their best efforts to have 5-year employment agreements entered into between Bay
Isle and Messrs. Schaff and Pollock. Consummation of any such purchase of Bay
Isle shares by Berger LLC would be subject to a number of conditions, including
any required approval by Fund shareholders under the Investment Company Act of
1940. Bay Isle and Messrs. Schaff and Pollock are also compensated by Berger LLC
for providing administrative or consulting services relating to their joint
venture private account business.

TRADE ALLOCATIONS

                  While investment decisions for the Funds are made
independently by the advisor or sub-advisor, the same investment decision may be
made for a Fund and one or more accounts advised by the advisor or sub-advisor.
In this circumstance, should purchase and sell orders of the same class of
security be in effect on the same day, the orders for such transactions may be
combined by the advisor or sub-advisor in order to seek the best combination of
net price and execution for each. Client orders partially filled will, as a
general matter, be allocated pro rata in proportion to each client's original
order, although exceptions may be made to avoid, among other things, odd lots
and de minimis allocations. Execution prices for a combined order will be
averaged so that each participating client receives the average price paid or
received. 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 LLC, the Berger Funds and Berger Distributors LLC each
permits its directors, officers and employees to purchase and sell securities
for their own accounts in accordance with a policy regarding personal investing
in each of the Codes of Ethics for Berger LLC, the Berger Funds and Berger
Distributors LLC. The policy 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 LLC's other advisory clients. Directors and
officers of Berger LLC and Berger Distributors LLC, investment personnel and
other designated 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 policy. Requests for authority to trade will be
denied pre-clearance when, among other reasons, the proposed personal
transaction would be contrary to the provisions of the policy 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
for Berger LLC and Berger Distributors LLC, the policy subjects directors and
officers of Berger LLC, the Berger Funds and Berger Distributors LLC, investment
personnel and other access persons to various trading restrictions and reporting
obligations. All reportable transactions are reviewed for compliance with the
policy. The policy is administered by Berger LLC and the provisions of the
policy 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 LLC.


                  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.

                  Bay Isle permits its officers, directors, employees and
consultants to purchase and sell securities for their own accounts and accounts
of related persons in accordance with provisions governing personal securities
trading in Bay Isle's code of ethics and related internal policies. Employees
must wait 3 days between the time a new recommendation or opinion change is made
and the time the employee may trade in those securities in their own or related
accounts, or alternatively may ask that their transaction be added to a "block"
trade that will be made for a group of clients. Any employee trade not included
in a "block" trade made must be pre-cleared if the trade exceeds certain
specified volume limits. Volume limits are set with the intent of requiring
prior approval of any trade that could potentially cause changes in the market
price of the security in question. In addition, no employee may sell (or buy)
any security which he or she has bought (or sold) within the past 5 trading days
unless a loss is realized on closing the position. No employee, officer or
director of Bay Isle may acquire any security in an initial public offering or
in a private placement without prior written approval from Bay Isle's President.
Any Bay Isle employee who is an "access person" of the Fund will also be subject
to the provisions of Berger LLC's Code of Ethics, if those provisions are more
restrictive than the provisions of Bay Isle's own code. Each employee must
acknowledge quarterly that they are in compliance with the Bay Isle code of
ethics and related policies.

5.                EXPENSES OF THE FUNDS


ALL FUNDS EXCEPT THE BERGER INTERNATIONAL FUND



                  In addition to paying an investment advisory fee to its
advisor, each Fund (other than the Berger 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 LLC, 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 LLC 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. For the fiscal year ended September 30, 1999, each Fund paid Berger
LLC a fee, before any waivers, at an annual rate of 0.01% of its average daily
net assets for such services. Effective October 1, 1999, Berger LLC eliminated
the 0.01% administrative fee charged to the Funds. The administrative services
fees may be changed by the directors or trustees without shareholder approval.
In addition, Effective October 1, 1999, the investment advisory fee charged to
certain funds was reduced. The advisory fee reductions are reflected earlier
under Investment Advisory Agreements.

                  The following tables show the total dollar amounts of advisory
fees and administrative services fees paid by each of such Funds for the periods
indicated and the amount of such fees waived on account of excess expenses under
applicable expense limitations. Except where noted, these amounts were paid to
Berger LLC.

</TABLE>

(1) The Fund's fiscal year changed from February 28 to September 30 as part of a
reorganization effective July 1999.

(2) Under the advisory agreement in effect prior to the reorganization
referenced in note (1), the Fund's predecessor paid an advisory fee at an annual
rate of 0.95% of its average daily net assets to Bay Isle. As part of the
reorganization, the investment advisory fee of 0.90% payable to Berger LLC came
into effect. Effective October 1, 1999, the investment advisory fee charged to
the Fund was reduced to 0.85% of the first $500 million of average net assets;
0.80% on the next $500 million of average net assets; and 0.75% of average net
assets exceeding $1 billion.

(3) Under the administrative service agreement in effect prior to the
reorganization referenced in note (1), the Fund's predecessor paid to a third
party administrator an administrative services fee at the annual rate of 0.20%
of average net assets, subject to a $30,000 annual minimum. As part of the
reorganization, the administrative service fee of 0.01% payable to Berger LLC
came into effect. Effective October 1, 1999, Berger LLC eliminated the 0.01%
administrative fee charged to the Funds.

(4) Prior to the reorganization referenced in note (1), the Fund's prior advisor
had voluntarily agreed to reduce its fees and/or pay expenses of the Fund to
ensure that the Fund's expenses did not exceed 1.50%. During 1998, in addition
to waiving its entire advisory fee and reimbursing the Fund for the entire
administrative service fee, the Fund's prior advisor reimbursed the Fund for
$59,000 of additional expenses in order to meet the applicable expense
limitation. As part of the reorganization, the current expense limitation
arrangements came into effect with Berger LLC, which are described in note (2)
to the table appearing above under the heading "Investment Advisory Agreements."

(5) The Fund was the accounting survivor in the reorganization referenced in

BERGER INTERNATIONAL FUND



                  The Berger International Fund is allocated and bears
indirectly its pro rata share of the aggregate annual operating expenses of the
Berger 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 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 International Fund include, among
others, its pro rata share of the expenses of the Berger 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 other
non-recurring and extraordinary items as may arise from time to time.



                  SERVICE ARRANGEMENTS FOR THE FUND. Under an Administrative
Services Agreement with the Berger International Fund, Berger LLC 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. Berger 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 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 Berger a fee at an annual rate
equal to the lesser of (i) 0.45% of its average daily net assets, or (ii)
Berger's annual cost to provide or procure these services (including the fees of
any services providers whose services are procured by Berger), 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 pursuant to the
Administrative Services Agreement. In addition, in the event that Berger's
duties under the Administrative Services Agreement are delegated to another
party, Berger may take into account, in calculating the cost of such services,
only the costs incurred by such other party in discharging the delegated duties.
Prior to May 12, 2000 BBOI Worldwide served as the Fund's administrator, in
which capacity it was responsible for providing these services.

<PAGE>   90


                  Also prior to May 12, 2000, under a Sub-Administration
Agreement then in effect between BBOI Worldwide and Berger LLC, Berger was
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 LLC. Under the Sub-Administration Agreement, Berger LLC
was paid a fee of 0.25% of the Fund's average daily net assets for its services.
During certain periods, Berger LLC voluntarily waived all or a portion of its
fee, which did not affect the fee paid by the Fund to BBOI Worldwide.

                  State Street 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, State Street has been appointed to serve as the Fund's
custodian, and DST has been appointed to serve as the Fund's transfer agent and
dividend disbursing agent. The fees of State Street and DST are all paid by
Berger LLC. Approximately 32% of the outstanding shares of DST are owned by
Stilwell.



                  SERVICE ARRANGEMENTS FOR THE PORTFOLIO. Under the Investment
Advisory Agreement between Berger LLC and the Berger International Portfolio, in
addition to providing investment advisory services, Berger is responsible for
providing or arranging for all managerial and administrative services necessary
for the operations of the Portfolio. Berger 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 LLC 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. Prior to May 12, 2000, BBOI
Worldwide served as the Fund's administrator, in which capacity it was
responsible for providing these services.



                  The Portfolio has appointed State Street 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 State Street as its
custodian. The Portfolio has appointed DST to serve as its transfer agent. For
custodian, recordkeeping and pricing services, the Portfolio pays fees directly
to State Street based on a percentage of its net assets, subject to certain
minimums, and reimburses State Street for certain out-of-pocket expenses.

                  The following table shows the total dollar amounts of advisory
fees paid by the Portfolio to BBOI Worldwide for the periods indicated and the

                  As noted above with respect to the other Berger Funds, all of
State Street's fees are subject to reduction pursuant to an agreed formula for
certain earnings credits on the cash balances maintained with it as custodian.

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 LLC 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 Plans are intended to benefit the Funds by attracting new
assets into the Funds and thereby affording potential cost reductions due to
economies of scale.

         The expenses paid by Berger LLC 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 LLC) 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


                                      -40-
<PAGE>   92

         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 LLC 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 LLC with respect to each fiscal year of the Fund without regard to the
actual distribution expenses incurred by Berger LLC in such year; that is, if
the distribution expenditures incurred by Berger LLC are less than the total of
such payments in such year, the difference is not to be reimbursed to the Fund
by Berger LLC, and if the distribution expenditures incurred by Berger LLC are
more than the total of such payments, the excess is not to be reimbursed to
Berger LLC 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 LLC, which costs are not readily
identifiable as related to any one fund. In such cases, a Fund's 12b-1 fees may
be used to finance the joint promotion of the shares of that Fund, along with
the shares of the other fund. Berger LLC allocates the cost of such joint
promotional 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 2001, 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.


                    Following are the payments made to Berger LLC pursuant to
the Plans for the fiscal year ended September 30, 1999:

(1) The Fund did not start offering the Investor Shares class of shares bearing
a 12b-1 fee until July 1999.


(2) The Berger Information Technology Fund, the Berger New Generation Fund, and
the Berger Small Company Growth Fund have adopted a 12b-1 Plan only with respect
to the Investor Shares class of shares, which is the class of shares of those
Funds covered by this SAI.


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 LLC due to the ownership interest of Stilwell in both DST
and Berger LLC.

                    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.

                    The Fund's advisor may also enter into arrangements with
organizations that solicit clients for the advisor, which may include clients
who purchase shares of the Funds. While the specific terms of each arrangement
may differ, generally, the fee paid by the advisor under such arrangements is
based on the value of the referred client's assets managed by the advisor. None
of the fees paid to such organizations will be borne by the Funds.

DISTRIBUTOR

                    The distributor (principal underwriter) of each Fund's
shares is Berger Distributors LLC (the "Distributor"), 210 University Boulevard,
Suite 900, Denver, CO 80206. The Distributor may be reimbursed by Berger LLC 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. Where
applicable, the advisor may delegate placement of brokerage to a Fund's
sub-advisor. 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:

(1) The Fund's fiscal year changed from February 28 to September 30 as part of a
reorganization effective July 1999. Accordingly, the brokerage commissions shown
for 1997 were paid by the Fund's predecessor during the period April 8, 1997
(commencement of operations of the predecessor) to February 28, 1998, and the
brokerage commissions shown for 1998 were paid by the Fund's predecessor during
its fiscal year ended February 28, 1999. Brokerage commissions shown for 1999
were paid by the Fund for the period from March 1, 1999 through September 30,
1999.

(2) Covers period from December 31, 1997 (commencement of operations) through
the end of the Fund's first fiscal year on September 30, 1998.


(3) Covers period from August 12, 1998 (commencement of operations) through the
end of the Fund's first fiscal year on September 30, 1998.



(4) These are brokerage commissions paid by the Portfolio in which all the
Fund's investable assets are invested. Commissions paid by the Portfolio are
borne indirectly pro rata by the Fund and the other mutual funds invested in the
Portfolio. The brokerage commissions shown for 1997 cover the period November 7,
1996 (commencement of Fund investment 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. Where applicable, the Sub-Advisory Agreement for each sub-advised Fund
similarly directs the sub-advisor. However, each Agreement specifically
authorizes the advisor or sub-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 or sub-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 or sub-advisor.
Accordingly, the advisor or sub-advisor does not have an obligation to seek the
lowest available commission.

                    In accordance with this provision of the Agreement,
portfolio brokerage business of each Fund may be placed with brokers who provide
useful brokerage and research services to the advisor or, where applicable, the
sub-advisor. The Fund's advisor or sub-advisor may consider the value of
research provided as a factor in the choice of brokers. "Research" includes
computerized on-line stock quotation systems and related data feeds from stock
exchanges, computerized trade order entry, execution and confirmation systems,
fundamental and technical analysis data and software, computerized stock market
and business news services, economic research, account performance data and
computer hardware used for the receipt of electronic research services and
broker and other third-party equity research, such as publications or writings
which furnish advice as to the value of securities and advisability of
investing, and analyses and reports concerning issuers, industries, securities,
market trends, and portfolio strategies. Research may be provided orally, in
print, or electronically. These include a service used by the independent
directors or trustees of the Funds in reviewing the Investment Advisory
Agreements.

                    In some cases, a product or services termed "research" may
serve other functions unrelated to the making of investment decisions. When a
product has such a mixed use, the advisor or sub-advisor will make a good faith
allocation of the cost of the product according to the use made of it. The
portion of the product that assists the advisor or sub-advisor in the investment
decision-making process may be paid for with a Fund's commission dollars. The
advisor or sub-advisor pays for the portion of the product that is not
"research" with its own funds. Accordingly, the decision whether and how to
allocate the costs of such a product presents a conflict of interest for the
advisor or sub-advisor.

                    The Funds' advisors and sub-advisors do not enter into
formal agreements with any brokers regarding the placement of securities
transactions because of any such brokerage or research services that they
provide. An advisor or sub-advisor may, however, make arrangements with and
maintain internal procedures for allocating transactions to brokers who provide
such services to encourage them to provide services expected to be useful to the
advisor's or sub-advisor's clients, including the Funds. Brokers may suggest a
level of business they would like to receive in return for the brokerage and
research they provide. The advisor or sub-advisor then determines whether to
continue receiving the research and brokerage provided and the approximate
amount of commissions it is willing to pay to continue the brokerage and
research arrangement with each broker. The actual amount of commissions a broker
may receive may be more or less than a broker's suggested allocations, depending
on the advisor's or sub-advisor's level of business, market conditions and other
relevant factors. Even under these arrangements, however, the placement of all
Fund transactions, must be consistent with the Funds' brokerage placement and
execution policies, and must be directed to a broker who renders satisfactory
service in the execution of orders at the most favorable prices and at
reasonable commission rates.

</TABLE>


(1) The Fund's fiscal year changed from February 28 to September 30 as part of a
reorganization effective July 1999. Accordingly, the amounts shown cover the
period from March 1, 1999 through September 30, 1999.

                    These brokerage and research services received from brokers
are often helpful to the advisor or sub-advisor in performing its investment
advisory responsibilities to the Funds, 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 brokerage and 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 brokerage and 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 or sub-advisor from the Funds be reduced as a result
of the availability of such brokerage and 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 LLC due to the ownership interest of Stillwell in both
DST and Berger LLC.

                    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:

(1) No portion of the commission is retained by DSTS. Difference between
commissions paid through DSTS and reduction in expenses constitute commissions
paid to an unaffiliated clearing broker.

(commencement of operations of the predecessor) to February 28, 1998, and the
amounts shown for FYE 9/30/98 were paid by the Fund's predecessor during its
fiscal year ended February 28, 1999. Amounts shown for FYE 9/30/99 cover the
period for March 1, 1999 to September 30, 1999.

                    Each Fund's advisor or sub-advisor places securities orders
with a limited number of major institutional brokerage firms chosen for the
reliability and quality of execution; commission rates; quality of research
coverage of major U.S. companies, the U.S. economy and the securities markets;
promptness; back office capabilities; capital strength and financial stability;
prior performance in serving the advisor and its clients; and knowledge of other
buyers and sellers. The advisor or sub-advisor selects the broker for each order
based on the factors above, as well as the size, difficulty and other
characteristics of the order. The directors or trustees of the Funds have also
authorized sales of shares of the Funds 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, the advisor or sub-advisor
may also consider 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, such as transfer agency fees. In placing portfolio business
with any such broker or dealer, the advisor will seek the best execution of each
transaction.

                    During the fiscal year ended September 30, 1999, Berger
Growth and Income Fund, Berger Balanced Fund and Berger Mid Cap Value Fund
acquired securities of the Funds' regular broker dealers. As of September 30,
1999, these Funds owned the following securities of its regular broker-dealers
with the following values:

7.                HOW TO PURCHASE AND REDEEM SHARES IN THE FUNDS

                  MINIMUM INITIAL INVESTMENTS:
                           Regular investment                          $2,000
                           Low Minimum Investment Plan                 $  100

                  MINIMUM SUBSEQUENT INVESTMENTS:
                           Regular investment                          $   50
                           Regular automatic investment                $   50
                           Low Minimum Investment Plan
                           (required monthly automatic investments)    $  100

                  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 following address:

                  Berger Funds
                  P.O. Box 219958
                  Kansas City, MO  64121

                  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 LLC may, at its own risk, waive certain of those
procedures and related requirements.

                  As described in the Prospectus, the Berger Information
Technology Fund will deduct a 1% redemption fee from a shareholder's redemption
proceeds if the shareholder redeems shares of that Fund held less than 6 months.
Because an exchange involves a redemption of shares followed by a purchase, this
redemption fee will also apply to exchanges of Fund shares held less than 6
months. This fee is intended to discourage investors from short-term trading of
Fund shares and to offset the cost to the Fund of excess brokerage and other
costs incurred as a result of such trading. This fee will not be charged to
retirement plan accounts (such as 401(k)s and 403(b)s) or in the case of
redemptions resulting from the death of the shareholder. This fee will also not
be charged on the redemption of shares obtained through the reinvestment of
dividends paid on Fund shares. If some but not all of the shares in an account
are redeemed, shares are treated as redeemed in an order determined by and
applied uniformly to all accounts by the Fund's sub-transfer agent.

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 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.

                  For those Funds offering classes of shares, net asset value is
calculated by class, and since the Investor Shares and each other class of those
Funds has its own expenses, the per share net asset value of those Funds will
vary by class.


                  Since the Berger International Fund invests all of its
investable assets in the Berger 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. Examples would be when events occur that materially affect the value
of a security at a time when the security is not trading or when the securities
are illiquid.

                  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 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 12 months will be subject to a maximum tax rate of 20% and net capital
gains from assets held for 12 months 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. Assets contributed to a Fund in an
in-kind purchase of Fund shares may generate more gain upon their sale than if
the assets had been purchased by the Fund with cash contributed to the Fund in a
cash purchase of 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. 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 redemption of their Fund shares. In general, redemptions 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, for the Funds
that make an election, 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 tax and interest


                                      -48-

<PAGE>   100

charges. However, the Fund may be eligible to elect one of two alternative tax
treatments with respect to PFIC shares which would avoid these taxes and
charges, but also may affect, among other things, the amount and character of
gain or loss and the timing of the recognition of income with respect to PFIC
shares. Accordingly, the amounts, character and timing of income distributed to
shareholders of a Fund holding PFIC shares may differ substantially as compared
to a fund that did not invest in PFIC shares.

                  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 a 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 INTERNATIONAL PORTFOLIO. The Berger
International Portfolio, in which the Berger International Fund invests all of
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 International Fund is treated for various federal tax
purposes as owning an allocable share of the Portfolio's assets and will be
allocated a 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
redeeming shareholder may have difficulty selling the securities and recovering
the amount of the redemption if the securities are illiquid. 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 offered by the Funds, please call 1-800-333-1001 or
write to the Funds c/o Berger LLC, 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. State Street 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 59 1/2 and must begin no later than April 1 of the calendar year
following the year in which the participant attains age 70 1/2. 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 70 1/2, 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 Berger Funds,
c/o Berger LLC, 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
Berger 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 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.

<PAGE>   102


                  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, State Street 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 59 1/2 and must begin no later than April 1 of the
calendar year following the year in which you attain age 70 1/2. Since
distributions which do not satisfy these requirements can result in adverse tax
consequences, consultation with an attorney or tax advisor is recommended. You
should also consult with your tax advisor about state taxation of your account.

                  In order to receive the necessary materials to create an IRA
account, please write to the Berger Funds, c/o Berger LLC, 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 fair market value of the existing
IRA on the date of the rollover. Please consult your tax advisor concerning Roth
IRA rollovers.

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
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 70 1/2 or the
calendar year in which you retire. Except for required distributions after age
70 1/2 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. State Street 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 Berger Funds, c/o Berger LLC, 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 Government Securities Portfolio
or the Tax-Exempt Portfolio of the Cash Account Trust ("CAT Portfolios"),
separately managed, unaffiliated money market funds, without charge, after
receiving a current prospectus of the other Fund or CAT Portfolio. The exchange
privilege with the CAT Portfolios does not constitute an offering or
recommendation of the shares of any such CAT Portfolio by any of the Funds or
Berger LLC. Berger LLC is compensated for administrative services it performs
with respect to the 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. In
addition, exchanges out of the Berger Information Technology Fund will be
subject to a redemption fee of 1% if shares are exchanged within 6 months of
purchase.

                  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 may be terminated or amended by any of
the Funds, and is not available in any state in which the shares of the Fund or
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., 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 Wilshire 5000 Index, 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, the Lehman Brothers
Intermediate Term Government/Corporate Bond Index or the InformationWeek 100
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, 3, 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 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 INTERNATIONAL FUND. The Berger International Portfolio
(in which all the investable assets of the Berger 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. At that time, BIAM's bank holding company parent
indirectly owned 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 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 LLC.


                  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.

                                      -53-

<PAGE>   105


                  Performance data quoted for the Berger 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 INFORMATION TECHNOLOGY FUND. The Berger Information
Technology Fund is the accounting survivor and successor of a fund previously
known as the InformationTech 100(R) Fund, which was reorganized into the Fund
effective July 2, 1999. As part of the reorganization, all of the then-existing
shares of the predecessor fund were exchanged for Institutional Shares of the
Fund, and the Fund commenced offering the Investor Shares covered in this
Statement of Additional Information.

                  The Fund quotes its historical performance track record for
both of its classes of shares based on its predecessor's only shares outstanding
prior to the reorganization. Accordingly, performance data for the Investor
Shares for periods prior to the date of the reorganization do not reflect the
0.25% per year 12b-1 fee currently borne by 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 for
various periods ending September 30, 1999, are shown on the following table:

(2) Performance data for the Investor Shares include periods prior to the Fund's
adoption of class designations on February 14, 1997, and therefore, for those
periods, do not reflect the 0.25% per year 12b-1 fee applicable to the Investor
Shares, which came into effect on that date.

(3) Covers the period from October 21, 1987 (date of the Fund's first public
offering) through September 30, 1999.

(4) Life of Fund covers the period from September 30, 1974 (immediately prior to
Berger LLC assuming the duties as the investment advisor for those Funds)
through September 30, 1999. Since the 12b-1 fees for the Berger Growth Fund and
the Berger Growth and Income Fund did not take effect until June 19, 1990, the
performance figures on the table do not reflect the deduction of the 12b-1 fees
for the full length of the 10-year and longer periods.


(5) Data for the Berger International Fund covering periods prior to October 11,
1996, reflect the performance of the pool of assets transferred on that date
into the Berger International Portfolio in which all of the Fund's assets are
invested, adjusted at that time to reflect any increase in expenses expected in
operating the Fund, including the Fund's pro rata share of the aggregate annual
operating expenses, of the Portfolio net of fee waivers.


14.               ADDITIONAL INFORMATION

FUND ORGANIZATION


                  BERGER GROWTH FUND AND BERGER GROWTH AND INCOME FUND. The
Berger Growth 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(R)", "Berger 100 FundSM",
"Berger One Hundred and One Fund(R)" and "Berger 101 Fund(R)" were adopted by
the respective Funds as service marks and trade names in November 1989 and were
registered as service marks in December 1991. 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. The name
"Berger Growth and Income Fund(R)" was registered as a service mark in August
1998. In January 2000, The One Hundred Fund, Inc. and the Berger One Hundred and
One Fund, Inc. formally changed their corporate names to the "Berger Growth
Fund" and the "Berger Growth and Income Fund" respectively and the name "Berger
Growth FundSM" was adopted as a trade name.


                  Each of the Berger Growth 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 Growth 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, BERGER MID CAP GROWTH FUND, BERGER MID
CAP VALUE FUND AND BERGER INFORMATION TECHNOLOGY 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(R)"
was registered as a service mark in September 1995. The Berger Small Company
Growth Fund had no class designations until July 6, 1999, when all of the
then-existing shares were designated as Investor Shares, which are covered in
this Statement of Additional Information, and the Fund commenced offering a
separate class known as Institutional Shares covered in a separate Prospectus
and Statement of Additional Information.

                  The Berger New Generation Fund was the second series created
under the Berger Investment Portfolio Trust, established on December 21, 1995.
The name "Berger New Generation Fund(R)" was registered as a service mark in
December 1996. The Berger Balanced Fund was the third series created under the
Berger Investment Portfolio Trust, established on August 22, 1997. The name
"Berger Balanced Fund(R)" was registered as a service mark in September 1998.
The Berger New Generation Fund had no class designations until July 6, 1999,
when all of the then-existing shares were designated as Investor Shares, which
are covered in this Statement of Additional Information, and the Fund commenced
offering a separate class known as Institutional Shares covered in a separate
Prospectus and Statement of Additional Information.

                  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 Berger Mid Cap Value Fund was the sixth series created under the
Berger Investment Portfolio Trust, established on May 21, 1998.

                  The Berger Information Technology Fund was the seventh series
created under the Berger Investment Portfolio Trust, established on February 18,
1999. The Fund is the successor to the fund formerly known as the
InformationTech 100(R) Fund. The InformationTech 100(R) Fund commenced
operations on April 8, 1997, as a separate series of the Advisors Series Trust,
a Delaware business trust. The InformationTech 100(R) Fund was then reorganized
into the Fund in a transaction that became effective in July 1999. As part of
the reorganization, all of the then-existing shares of the predecessor fund were
exchanged for Institutional Shares of the Fund, and the Fund commenced offering
the Investor Shares covered in this Statement of Additional Information.

                  The Trust is authorized to issue an unlimited number of shares
of beneficial interest in series or portfolios. Currently, the Funds named above
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 INTERNATIONAL FUND. The Berger Worldwide Funds Trust is
a Delaware business trust organized on May 31, 1996, under the name Berger/BIAM
Worldwide Funds Trust. In May, 2000, the Trust changed its name to Berger
Worldwide Funds Trust. The Berger International Fund was established on May 31,
1996, as a series of the Trust. The Fund was originally named the Berger/BIAM
International Fund and changed its name in May 2000 to the Berger International
Fund. 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 Worldwide Portfolios Trust is also a Delaware business
trust organized on May 31, 1996, under the name Berger/BIAM Worldwide Portfolios
Trust. In May 2000, the Trust changed its name to Berger Worldwide Portfolios
Trust. The Berger International Portfolio (in which all of the investable assets
of the Berger International Fund are invested) was established on May 31, 1996,
as a series of that Trust. The Portfolio was originally named the Berger/BIAM
International Portfolio and changed its name in May 2000 to the Berger
International Portfolio. Like the Berger 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 pooled trust.
See "Performance Information -- Predecessor Performance Data -- Berger
International Fund" in Section 13 above for additional information on the asset
transfer. The Berger 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.


                                      -56-

<PAGE>   108

                  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.



                  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 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.



                  CORPORATE GOVERNANCE AND OTHER 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 Growth 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/classes of the same business trust, generally vote separately on matters
relating to those respective series/classes, although they vote together and
with the holders of any other series/classes 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.

                                      -57-

<PAGE>   109


                  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 conversion rights, except
that shareholders of any class of the Berger Information Technology 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.


                  Under governing corporate law, each Fund may enter into a
variety of corporate transactions, such as reorganizations, conversions, mergers
and asset transfers, or may be liquidated. Any such transaction would be subject
to a determination from the directors or trustees that the transaction was in
the best interests of the Fund and its shareholders, and may require obtaining
shareholder approval.

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 Information Technology
Fund, the Berger New Generation Fund and the Berger Small Company Growth Fund
have divided their shares into classes and have two classes of shares
outstanding, the Investor Shares covered by this SAI and the Institutional
Shares offered through a separate Prospectus and SAI. These Funds implemented
their multi-class structure by adopting Rule 18f-3 Plans under the 1940 Act
permitting them to issue shares in classes. The Rule 18f-3 Plans govern 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 $250,000. Information concerning Institutional Shares is
available from the Funds at 1-800-259-2820.


                  Subject to the relevant Declaration of Trust or Trust
Instrument and any other applicable provisions, the trustees of those Funds 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 International Fund
(referred to as a feeder fund) seeks to achieve its investment objective by
investing all of its investable assets in the Berger 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.
Currently, there are two other feeder funds that also invest all of their
investable assets in the Portfolio: the International Equity Fund (designed for
eligible trusts or bank trust departments), and the Berger International CORE
Fund, both of which have a minimum balance requirement of $1,000,000.


                  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 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.

                                      -58-

<PAGE>   110

                  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 Worldwide Funds Trust and the
Berger 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.


PRINCIPAL SHAREHOLDERS

                  Insofar as the management of the Funds is aware, as of January
4, 2000, no person owned, beneficially or of record, more than 5% of the
outstanding shares of any of the Funds, except for the following:

                  Any person owning more than 25% of the outstanding securities
of a Fund may be deemed to control it. Schwab and Fidelity are believed to hold
their shares of the Funds as nominees for the benefit of their client.


                  In addition, Schwab owned of record 26.08%, and Fidelity owned
of record 8.52% of all the outstanding shares of the Berger Investment Portfolio
Trust, of which the Berger Information Technology Fund, Berger New Generation
Fund, Berger Select Fund, Berger Small Company Growth Fund, Berger Mid Cap
Growth Fund, Berger Mid Cap Value Fund and the Berger Balanced Fund are
outstanding series. Schwab also owned of record 18.37% of the outstanding shares
of the Berger Worldwide Funds Trust, of which the Berger International Fund is
one of three outstanding series.


                  As of January 4, 2000, Schwab owned of record 57.28% of the
outstanding shares of the Berger Information Technology Fund, a series of the
Berger Investment Portfolio Trust, when Schwab's record ownership of the Fund's
Trust shares is added together with record ownership of Institutional Shares of
the Fund. In addition, Bay Isle has advised the Trust that, as January 4, 2000,
it had voting discretion over approximately 27.60% of that fund's outstanding
shares in accounts beneficially owned by various Bay Isle advisory clients. Bay
Isle may be deemed to beneficially own those shares as a result of its voting
discretion.

                                   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
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.

                                      -62-

<PAGE>   114

         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 a 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.
