"multi-style" approach is designed to minimize the volatility and risk of
investing in a single investment style.

Diversified Small Cap Fund

Objective
Seeks long-term capital appreciation while moderating annual return volatility.

Principal Strategy
We invest in several (currently 5) styles of small capitalization equity
portfolios. This "multi-style" approach is designed to minimize the volatility
and risks of investing in small capitalization equity securities.

Equity Index Fund

Objective
Seeks to approximate the total rate of return of substantially all common stock
comprising the Standard & Poor's 500 Composite Index.

Principal Strategy
We invest in substantially all of the common stocks listed on the S&P 500 Index.

Equity Value Fund

the overall stock markets.

International Equity Fund

Objective
Seeks to earn total return, with an emphasis on capital appreciation, over the
long-term.

Principal Strategy
We invest in equity securities of companies located or operating in developed
foreign countries and emerging markets of the world. We apply a
fundamentals-driven value-oriented analysis to identify companies that we
believe have above-average potential for long-term growth.

International Fund

Objective
Seeks long-term capital appreciation.

Principal Strategy
We invest in two separate portfolios, an international equity portfolio
investing largely in the common stock of high-quality companies based outside of
the United States, and an international emerging markets portfolio. This
"multi-style" approach is designed to minimize the volatility and risk
associated with investing in the individual international portfolios.

Large Company Growth Fund

Objective
Seeks long-term capital appreciation.

Principal Strategy
We invest in the common stocks of large, high-quality domestic companies whose
market capitalization is greater than the median of the Russell 1000 Index,
currently about $3.7 billion, with superior growth potential.

Small Cap Opportunities Fund

Objective
Seeks long-term capital appreciation.

Principal Strategy
We invest in equity securities of small domestic companies that at the time of
purchase have market capitalizations of $1.5 billion or less, we look for
companies with above-average earnings growth.

Small Cap Value Fund

Objective
Seeks capital appreciation by investing primarily in common stocks of smaller
companies.

Principal Strategy
We invest in the common stocks of companies listed on the Russell 2000 Index,
which currently range in market capitalization from $220 million to $1.4
billion, that appear undervalued.

Summary Of Important Risks

 This section summarizes important risks that are common to all of the Funds
 described in this Prospectus, and important risks that relate specifically to
 particular Funds.  Both are important to your investment choice.  Additional
 information about these and other risks is included in the individual Fund
 Descriptions later in this Prospectus, under General Investment Risks beginning
 on page __ and in the Funds' Statement of Additional Information.  An
 investment in a Fund is not a deposit of Wells Fargo Bank and is not insured or
 guaranteed by the FDIC or any other government agency.

 Common Risks for the Funds

 Equity Securities.  The Funds invest in equity securities, which are subject to
 equity market risk.  This is the risk that stock prices will fluctuate and can
 decline and reduce the value of a Fund's portfolio.  Certain types of stock and
 certain individual stocks selected for a Fund's portfolio may underperform or
 decline in value more than the overall market.  As of the date of this
 Prospectus, the equity markets, as measured by the S&P 500 Index and other
 commonly used indexes, are trading at or close to record levels.  There can be
 no guarantee that these levels will continue.  The Funds that invest in smaller
 companies, in foreign companies (including investments made through American
 Depositary Receipts and similar instruments), and in emerging markets are
 subject to additional risks, including less liquidity and greater price
 volatility.  A Fund's investment in foreign companies and emerging markets are
 also subject to special risks associated with international investing,
 including currency, political, regulatory and diplomatic risks.

 Debt Securities.  The Funds may invest some of their assets in debt securities,
 such as notes and bonds, which are subject to credit risk and interest rate
 risk. Credit risk is the possibility that an issuer of an instrument will be
 unable to make interest payments or repay principal. Changes in the financial
 strength of an issuer or changes in the credit rating of a security may affect
 its value. Interest rate risk is the risk that interest rates may increase,
 which will reduce the resale value of instruments in a Fund's investments,
 including U.S. Government obligations. Debt securities with longer maturities
 are generally more sensitive to interest rate changes than those with shorter
 maturities. Changes in market interest rates do not affect the rate payable on
 debt instruments held in a Fund, unless the instrument has adjustable or
 variable rate features, which can reduce interest rate risk. Changes in market
 interest rates may also extend or shorten the duration of certain types of
 instruments, such as asset-backed securities, thereby affecting their value and
 the return on your investment.

Fund-Specific Risks

 Diversified Equity Fund
 Stocks selected for their high dividend yields may be more sensitive to
 interest rate changes than other stocks.  Also, stocks of the smaller and
 medium-sized companies purchased for this Fund may be more volatile and less
 liquid than larger company stocks.

 Diversified Small Cap Fund
 Stocks of smaller companies purchased for this Fund may be more volatile and
 less liquid than larger company stocks.

 Equity Index Fund
 We attempt to match as closely as possible the performance of the S&P 500
 Index.  Therefore, during periods when the S&P 500 Index is losing value, your
 investment will also lose value.

                                       6
<PAGE>

 Equity Value Fund
 There is no guarantee that securities selected as "under-valued" will perform
 as expected.  Stocks of smaller, medium-sized and foreign companies purchased
 using the value approach may be more volatile and less liquid than other
 comparable securities.

 Growth Equity Fund
 The Fund is primarily subject to the equity market risks described in the
 Common Risks section above. The advisor selects growth stocks based on
 prospects for future earnings, which may not grow as expected. In addition, at
 times, the overall market or the market for value stocks may outperform growth
 stocks.

 International Equity Fund
 Foreign company stocks involve special risks, including generally higher
 commission rates, political, social and monetary or diplomatic developments
 that could effect U.S. investments in foreign countries.  Emerging market
 countries may experience increased political instability, and are often
 dependent on international trade, making them more vulnerable to events in
 other countries.  They may have less developed financial systems and volatile
 currencies and may be more sensitive than more mature markets to a variety of
 economic factors.  Emerging market securities may also be less liquid than
 securities of more developed countries, which may make them more difficult to
 sell, particularly during a market downturn.  Additionally, dispositions of
 foreign securities and dividends and interest payable on those securities may
 be subject to foreign taxes.

 International Fund
 Foreign company stocks involve special risks, including generally higher
 commission rates, political, social and monetary or diplomatic developments
 that could effect U.S. investments in foreign countries.  Additionally,
 dispositions of foreign securities and dividends and interest payable on those
 securities may be subject to foreign taxes.

 Large Company Growth Fund
 The Fund is primarily subject to the equity market risks described in the
 Common Risks section above. The advisor selects growth stocks based on
 prospects for future earnings, which may not grow as expected. In addition, at
 times, the overall market or the market for value stocks may outperform growth
 stocks. Dividend-producing large company stocks have experienced unprecedented
 appreciation in recent years. There is no guarantee such performance levels
 will continue.

 Small Cap Opportunities Fund
 Stocks of smaller companies purchased for this Fund may be more volatile and
 less liquid than larger company stocks.

 Small Cap Value Fund
 There is no guarantee that securities selected as "under-valued" will perform
 as expected.  Stocks of smaller, medium-sized and foreign companies purchased
 using the value approach may be more volatile and less liquid than other
 comparable securities.

Diversified Equity Fund

Investment Objective
The Diversified Equity Fund's investment objective is to provide long-term
capital appreciation with moderate annual return volatility by diversifying its
investments among different equity investment styles.

Investment Policies
The Fund invests in a "multi-style" approach designed to minimize the volatility
and risk of investing in a single investment style. The Fund currently invests
in 11 Portfolios.

Permitted Investments
The Fund's investments combine 5 different equity investment styles -- an index
style, an income equity style, a large company style, a diversified small cap
style, and an international style. The Fund allocates the assets dedicated to
large company investments to 2 Portfolios, the assets allocated to small company
investments to 5 Portfolios, and the assets dedicated to international
investments to 2 Portfolios. Because Diversified Equity Fund blends 5 equity
investment styles, it is anticipated that is price and return volatility will be
less than that of Growth Equity Fund, which blends 3 equity investment styles.

Important Risk Factors
Stocks of foreign companies purchased by this Fund may be subject to political
and economic instability. Also, stocks of the smaller and medium-sized companies
purchased for this Fund may be more volatile and less liquid than larger company
stocks.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure. In this structure,
the "gateway" Diversified Equity Fund invests all of its assets in various
"core" portfolios whose objectives and investment policies are consistent with
the Fund's investment objective. Gateway funds investing in various core
portfolios can enhance their investment opportunities and reduce their expenses
through sharing the costs of managing a large pool of assets. References to the
investment activities of the Fund also refer to the investments of the core
portfolios in which it invests.

Diversified Small Cap Fund

Investment Objective
The Diversified Small Cap Fund's investment objective is to provide long-term
capital appreciation with moderate annual return volatility by diversifying its
investments across different small capitalization equity investment styles.

Investment Policies
The Fund invests in a "multi-style" approach designed to minimize the volatility
and risk of investing in small capitalization equity securities.

Permitted Investments
The Fund invests in several different small capitalization equity styles in
order to reduce the risk of price and return volatility associated with reliance
on a single investment style.  The Fund currently invests in 5 Portfolios.

Important Risk Factors
Stocks of smaller companies purchased for the Fund may be more volatile and less
liquid than larger company stocks.  Also, short term changes in the demand for
the securities of smaller companies may have a disproportionate effect on their
market price, tending to make the prices of these securities fall more in
response to selling pressure.

Equity Index Fund

Investment Objective
The Equity Index Fund seeks to approximate to the extent practicable the total
rate of return of substantially all common stocks comprising the Standard &
Poor's 500 Composite Stock Index (the "S&P 500 Index").

Investment Policies
We invest in substantially all of the common stocks listed on the S&P 500 Index
and attempt to achieve a 95% correlation between the performance of the S&P 500
Index and our investment results, before expenses.  This correlation is sought
regardless of market conditions.

A precise duplication of the performance of the S&P 500 Index would mean that
the net asset value of Fund shares, including dividends and capital gains would
increase or decrease in exact proportion to changes in the S&P 500 Index.  Such
a 100% correlation is not feasible.  Our ability to track the performance of the
S&P 500 Index may be affected by, among other things, transaction costs and
shareholder purchases and redemptions.  We will regularly monitor the
performance and composition of the S&P 500 Index, adjust the Fund's portfolio as
necessary in order to achieve the 95% correlation.

Permitted Investments
Under normal market conditions, we invest:

 .    in a diversified portfolio of common stocks designed to provide a relative
     sample of the stocks listed on the S&P 500 Index;
 .    in stock index futures and options on stock indexes as a substitute for
     comparable position in the underlying securities; and
 .    in interest-rate futures contracts, options or interest rate swaps and
     index swaps.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, either to maintain liquidity
or for short-term defensive purposes when we believe it is in the best interests
of shareholders to do so.  During such periods, the Fund may not achieve its
objective.

Important Risk Factors
We attempt to match as closely as possible the performance of the S&P 500 Index.
Therefore, during periods when the S&P 500 Index is losing value, your
investment will also lose value.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above. They
are all important to your investment choice.

Equity Value Fund

Investment Objective
The Equity Value Fund seeks to provide investors with long-term capital
appreciation.

Investment Policies
We seek long-term capital appreciation by investing in a diversified portfolio
composed primarily of equity securities that are trading at low price-to-
earnings ratios, as measured against the stock market as a whole or against the
individual stock's own price history.  In addition we look at the price-to-book
value and price-to-cash flow ratios of companies for indications of attractive
valuation.  We use both quantitative and qualitative analysis to identify
possible investments.  Dividends are a secondary consideration when selecting
stocks.  We may purchase particular stocks when we believe that a history of
strong dividends may increase their market value.

Permitted Investments
Under normal market conditions, we invest:

 .    primarily in common stocks of both large, well-established companies and
     smaller companies with market capitalization exceeding $50 million at the
     time of purchase;
 .    in debt instruments that may be converted into the common stock of both
     U.S. and foreign companies; and
 .    up to 25% of our assets in foreign companies through American Depositary
     Receipts and similar instruments.

We may also purchase convertible debt securities with the same characteristics
as common stock, as well as in preferred stock and warrants. We may temporarily
hold assets in cash or in money market instruments, including U.S. Government
obligations, shares of other mutual funds and repurchase agreements, or make
short-term investments, either to maintain liquidity or for short-term defensive
purposes when we believe it is in the best interests of shareholders. During
such periods, the Fund may not achieve its objective of long term capital
appreciation.

Important Risk Factors
There is no guarantee that securities selected as "undervalued" will perform as
expected.  Stocks of smaller, medium-sized and foreign companies purchased using
the value approach may be more volatile and less liquid than other comparable
securities.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

Growth Equity Fund

Investment Objective
The Growth Equity Fund's investment objective is to provide a high level of
long-term capital appreciation with moderate annual return volatility by
diversifying its investments among different equity investment styles.

Investment Policies
The Fund invests in a "multi-style" approach designed to reduce the volatility
and risk of investing in a single equity style.  The Fund currently invests in 8
Portfolios.

growth style, a diversified small cap style, and an international style.  The
Fund allocates the assets dedicated to small company investments to 5 Portfolios
and the assets dedicated to international investments to 2 Portfolios.  It is
anticipated that the Fund's price and return volatility will be somewhat greater
than those of Diversified Equity Fund, which blends 5 equity styles.

Important Risk Factors
This Fund is primarily subject to the equity market risks described in the
Common Risks section.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.

International Equity Fund

Investment Objective
The International Equity Fund seeks to earn total return, with an emphasis on
capital appreciation, over the long-term, by investing primarily in equity
securities of non-U.S. companies.

Investment Policies
We actively manage a diversified portfolio of equity securities of companies
located or operating in developed non-U.S. countries and in emerging markets of
the world.  We expect that the securities we hold will be traded on a stock
exchange or other market in the country in which the issuer is based, but they
also may be traded in other countries, including the U.S.

We apply a fundamentals-driven, value-oriented analysis to identify companies
with above-average potential for long-term growth. The financial data we examine
includes both the company's historical performance results and its projected
future earnings. Among other key criteria we consider are a company's local,
regional or global franchise; history of effective management demonstrated by
expanding revenues and earnings growth; prudent financial and accounting
policies and ability to take advantage of a changing business environment.

Permitted Investments
Under normal market conditions, we invest:

 .    at least 80% of our assets in equity securities of companies located or
     operating outside the U.S.;
 .    in a minimum of five countries exclusive of the U.S.;
 .    up to 50% of our assets in any one country;
 .    up to 25% of our portfolio in emerging markets;
 .    in issuers with an average market capitalization of $10 billion or more,
     although we may invest in equity securities of issuers with market
     capitalization as low as $250 million; and
 .    in equity securities including common stocks, and preferred stocks, and in
     warrants, convertible debt securities, ADRs, GDRs (and similar instruments)
     an shares of other mutual funds.

Although it is not our intention to do so, we reserve the right to hedge the
portfolio's foreign currency exposure by purchasing or selling foreign currency
futures and forward foreign currency contracts.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, either to maintain liquidity
or for short-term defensive purposes when we believe it is in the best interests
of shareholders to do so.  We may also, for defensive purposes, invest without
limit in cash, short-term debt and equity securities of U.S. companies when we
believe it is in the best interests of shareholders to do so.  During these
periods, the Fund may not achieve its objective of capital appreciation.

Important Risk Factors
Foreign company stocks may lose value or be more difficult to trade as a result
of adverse changes in currency exchange rates or other developments in the
issuer's home country.  Concentrated investment in any single country,
especially a less developed country, would make the Fund's value more sensitive
to economic, currency and regulatory changes within that country.  Emerging
market countries are often dependent on international trade and are therefore
often vulnerable to events in other countries.  They may have less developed
financial systems and volatile currencies and may be more sensitive than more
mature markets to a variety of economic factors.  Emerging market securities may
also be less liquid than securities of more developed countries, which may make
them more difficult to sell, particularly during a market downturn.

International Fund

Investment Objective
The International Fund's investment objective is to provide long-term capital
appreciation by investing directly or indirectly in high-quality companies based
outside the United States.

Investment Policies
The Fund invests in a "multi-style" approach designed to minimize the volatility
and risk of investing in international securities.

Permitted Investments
The Fund's investment portfolio combines 2 different investment styles -- an
international equity investment style and an international emerging markets
investment style.  The Fund invests in 2 Portfolios.

Important Risk Factors
Foreign company stocks may lose value or be more difficult to trade as a result
of adverse changes in currency exchange rates or other developments in the
issuer's home country.  Concentrated investment in any single country,
especially a less developed country, would make the Fund's value more sensitive
to economic, currency and regulatory changes within that country.  Emerging
market countries are often dependent on international trade and are therefore
often vulnerable to events in other countries.  They may have less developed
financial systems and volatile currencies and may be more sensitive than more

also be less liquid than securities of more developed countries, which may make
them more difficult to sell, particularly during a market downturn.

Large Company Growth Fund

Investment Objective
The Large Company Growth Fund's investment objective is to provide long-term
capital appreciation by investing primarily in large, high-quality domestic
companies that the Advisor believes have superior growth potential.

Investment Policies
The Fund invests primarily in the common stock of large, high-quality domestic
companies that have superior growth potential.

Permitted Investments
The Advisor considers large companies to be those whose Market Capitalization is
greater than the median of the Russell 1000 Index or approximately $3.7 billion.
In selecting securities for the Fund, the Advisor seeks issuers whose stock is
attractively valued with fundamental characteristics that are significantly
better than the market average and support internal earnings growth capability.
The Fund may invest in the securities of companies whose growth potential is, in
the Advisor's opinion, generally unrecognized or misperceived by the market.
The Fund may not invest more than 10% of its total assets in the securities of a
single issuer.

Important Risk Factors
The Fund may invest up to 20% of its total assets in the securities of foreign
companies and may hedge against currency risk by using foreign currency forward
contracts. Foreign company stocks may lose value or be more difficult to trade
as a result of adverse changes in currency exchange rates or other developments
in the issuer's home country. Concentrated investment in any single country,
especially a less developed country, would make the Fund's value more sensitive
to economic, currency and regulatory changes within that country. Emerging
market countries are often dependent on international trade and are therefore
often vulnerable to events in other countries. They may have less developed
financial systems and volatile currencies and may be more sensitive than more
mature markets to a variety of economic factors. Emerging market securities may
also be less liquid than securities of more developed countries, which may make
them more difficult to sell, particularly during a market downturn.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure. In this structure,
the "gateway" Large Company Growth Fund invests all of its assets in a "core"
portfolio that has a substantially identical investment objective and
substantially similar polices as the gateway fund. Gateway funds investing in
the same core portfolio can enhance their investment opportunities and reduce
their expense ratios through sharing the costs of managing a large pool of
assets. References to the investment activities of the Fund also refer to the
investment activities of the core portfolio.

Small Cap Opportunities Fund

Investment Objective
The Small Cap Fund's investment objective is to provide capital appreciation.

Investment Policies
The Fund invests primarily in equity securities of U.S. companies that, at the
time of purchase, have Market Capitalizations of $1.5 billion or less.

The Advisor attempts to identify securities of companies that it believes can
generate above-average earnings growth and sell at favorable prices in relation
to book values and earnings. The Advisor's assessment of a company's
management's competence will be an important consideration. These criteria are
not rigid and the Fund may make other investments to achieve its objective.

Permitted Investments
The Fund will invest principally in equity securities, including common stocks,
securities convertible into common stocks or, subject to special limitations,
rights or warrants to subscribe for or purchase common stocks. The Fund also
may invest to a limited degree in non-convertible debt securities and preferred
stocks.

The Fund may use options and futures contracts to manage risk. The Fund also
may use options to enhance return.

Important Risk Factors
This Fund is designed for investors willing to assume above-average risk. We
may invest in companies that:

 .   pay low or no dividends;
 .   have smaller market capitalization;
 .   have less market liquidity;
 .   have no or relatively short operating histories, or are new public companies
    or are initial public offerings;
 .   have aggressive capital structures including high debt levels; or
 .   are involved in rapidly growing or changing industries and/or new
    technologies.

Because we may invest in such aggressive securities, share prices may rise and
fall more than the share prices of other funds. In addition, our active trading
investment strategy may result in a higher-than-average portfolio turnover
ratio, increased trading expenses, and higher short-term capital gains.

Small Cap Value Fund

Investment Objective
The Small Cap Value Fund's investment objective is to seek capital appreciation
by investing primarily in common stocks of smaller companies.

Investment Policies
The Fund seeks capital appreciation by investing in common stocks of smaller
companies. The Fund will normally invest substantially all of its assets in
securities of companies with Market Capitalizations that reflect the Market
Capitalization of companies included in the Russell 2000 Index, which range from
approximately $220 million to approximately $1.4 billion.

Permitted Investments
The Fund seeks higher growth rates and greater long-term returns by investing
primarily in the common stock of smaller companies that the Advisor believes to
be undervalued and likely to report a level of corporate earnings exceeding the
level expected by investors. The Advisor values companies based upon both the
price-to-earnings ratio of the company and a comparison of the public market
value of the company to a proprietary model that values the company in the
private market. In seeking companies that will report a level of earnings
exceeding that expected by investors, the Advisor uses both quantitative and
fundamental analysis. Among other factors, the Advisor considers changes of
earnings estimates by investment analysts, the recent trend of company earnings
reports, and the fundamental business outlook for the company.

Important Risk Factors
This Fund is designed for investors willing to assume above-average risk. We
may invest in companies that:

 .   pay low or no dividends;
 .   have smaller market capitalization;
 .   have less market liquidity;
 .   have no or relatively short operating histories, or are new public companies
    or are initial public companies
    or are initial public offerings;
 .   have aggressive capital structures including high debt levels; or
 .   are involved in rapidly growing or changing industries and/or new
    technologies.

Because we may invest in such aggressive securities, share prices may rise and
fall more than the share prices of other funds.  In addition, our active trading
investment strategy may result in a higher-than-average portfolio turnover
ratio, increased trading expenses, and higher short-term capital gains.

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds.  Certain common risks are identified in the
Summary of Important Risks on page ___. Other risks of mutual fund investing
include the following:

 .   Unlike bank deposits, such as CDs or savings accounts, mutual funds are not
    in sured by the FDIC.
 .   We cannot guarantee that we will meet our investment objectives.
 .   We do not guarantee the performance of a Fund, nor can we assure you that
    the market value of your investment will not decline. We will not "make
    good" any investment loss you may suffer, nor can anyone we contract with to
    provide certain services, such as selling agents or investment advisors,
    offer or promise to make good any such losses.
 .   Share prices -- and therefore the value of your investment -- will increase
    and decrease with changes in the value of the underlying securities and
    other investments.
 .   Investing in any mutual fund, including those deemed conservative, involves
    risk, including the possible loss of any money you invest.
 .   An investment in a single Fund, by itself, does not constitute a complete
    investment plan.
 .   The Funds that invest in smaller companies, foreign companies (including
    investments made through American Depositary Receipts and similar
    instruments), and in emerging markets are subject to additional risks,
    including less liquidity and greater price volatility. A Fund's investment
    in foreign and emerging markets may also be subject to special risks
    associated with international trade, including currency, political,
    regulatory and diplomatic risk.
 .   The Funds may invest a portion of their assets in U.S. Government
    obligations. It is important to recognize that the U.S. Government does not
    guarantee the market value or current yield of those obligations. Not all
    U.S. M Government obligations are backed by the full faith and credit of the
    U.S. Treasury, and the U.S. Government's guarantee does not extend to the
    Funds themselves.
 .   The Funds may also use certain derivative instruments, such as options or
    futures contracts. The term "derivatives" covers a wide number of
    investments, but in general it refers to any financial instrument whose
    value is derived, at least in part, from the price of another security or a
    specified index, asset or rate. Some derivatives may be more sensitive to
    interest rate changes or market moves, and some may be susceptible to
    changes in yields or values due to their structure or contract terms.
 .   The Funds may temporarily hold assets in cash or in money market
    instruments, including U.S. Government obligations, shares of other mutual
    funds and repurchase agreements, or make other short-term investments,
    either to maintain liquidity or for short-term defensive purposes when we
    believe t is in the best interests of shareholders to do so. Except with
    respect to money market Funds, to the extent a Fund's assets are so
    invested, they may use a Fund to not achieve its investment objective. This
    practice is expected to have limited, if any, effect on the Funds' pursuit
    of their objectives over the long term.
 .   The Funds may invest a portion of their assets in U.S. Government
    obligations, such as securities issued or guaranteed by the Government
    National Mortgage Association (GNMAs"), the Federal National Mortgage
    Association ("FNMAs") and the Federal Home Loan Mortgage Corporation
    ("FHLMCs"). Each are mortgage-backed securities representing partial
    ownership of a pool of residential mortgage loans. A "pool" or group of such
    mortgages is assembled and, after being approved by the issuing or
    guaranteeing entity, is offered to investors through securities risk, which
    can alter the maturity of the securities and also reduce the rate of return
    on the portfolio. Collateralized mortgage obligations ("CMOs") typically
    represent principal-only and interest-only portions of such securities and
    are subject to increased interest-rate and credit risk.
 .   The market value of lower-rated debt securities and unrated securities of
    comparable quality that the Funds may invest in tends to reflect individual
    developments affecting the issuer to a greater extend than the market value
    of higher-rated securities, which react primarily to fluctuations in the
    general level of interest rates. Lower-rated securities also tend to be more
    sensitive to economic conditions than higher-rated securities. These lower-
    rated debt securities are considered by the rating agencies, on balance, to
    be predominantly speculative with respect to the issuer's capacity to pay
    interest and

                                       24
<PAGE>

    repay principal. These securities generally involve more credit risk than
    securities in higher-rating categories. Even securities rated "BBB" by S&P
    or by Moody's rating which are considered investment-grade, possess some
    speculative characteristics.

Investment practices and risk levels are carefully monitored. Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Fund and a table showing some of the
additional investment practices that each Fund may use and the risks associated
with them. Additional information about these practices is available in the
Statement of Additional Information.

Counter-Party Risk--The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

Credit Risk--The risk that the issuer of a debt security will be unable to
make interest payments or repay principal on schedule. If an issuer does
default, the affected security could lose all of its value, or be renegotiated
at a lower interest rate or principal amount.  Affected securities might also
lose liquidity. Credit risk also includes the risk that a party in a
transaction may not be able to complete the transaction as agreed.

Currency Risk--The risk that a change in the exchange rate between U.S. dollars
and a foreign currency may reduce the value of an investment made in a security
denominated in that foreign currency.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value of
liquidity of investments in either country.

Emerging Market Risk--The risk that the emerging market, as defined in the
glossary, may be more sensitive to certain economic changes. For example,
emerging market countries are often dependent on international trade and are
therefore often vulnerable to recessions in other countries. They may have
obsolete financial systems, have volatile currencies and may be more sensitive
than more mature markets to a variety of economic factors. Emerging market
securities may also be less liquid than securities of more developed countries
and could be difficult to sell, particularly during a market downturn.

Experience Risk--The risk presented by a new or innovative security. The risk
is that insufficient experience exists to forecast how the security's value
might be affected by various economic conditions:

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security. Generally, when interest rates increase, the value of
a debt security decreases. The effect is usually more pronounced for securities
with longer dates to maturity.

Leverage Risk--The risk that an investment practice, such as lending portfolio
securities or engaging in forward commitment or when issued securities
transactions, may increase a Fund's exposure to market risk, interest rate risk
or other risks by, in effect, increasing assets available for investment.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of a stock, bond or other security will be
reduced by market activity. This is a basic risk associated with all
securities.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

                                       25
<PAGE>

Prepaying Risk--The risk that consumers will accelerate their prepayment of
mortgage loans or other receivable, which can shorten the maturity of a mortgage
backed or other asset-backed security, and reduce a portfolio's return.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security. Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Year 2000 Risk--The Funds' principal service providers have advised the Funds
that they are working on the necessary changes to their computer systems to
avoid any system failure based on an inability to distinguish the year 2000 from
the year 1900, and that they expect their systems to be adapted in time. There
can, of course, be no assurance of success. In addition, the companies or
entities in which the Funds invest also could be adversely impacted by the Year
2000 issue, especially foreign entities, which may be less prepared for Year
2000. The extent of such impact cannot be predicted.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund. You should also
see the Statement of Additional Information for additional information about the
investment practices and risks particular to each Fund.

A number of different entities provide services to the Funds. This section
shows how the Funds are organized, lists the entities that perform different
services, and explains how these service providers are compensated. Further
information is available in the Statement of Additional Information for the
Funds.

About Wells Fargo Funds Trust
Wells Fargo Funds Trust (the "Trust") was organized as a Delaware business trust
on March 10, 1999. The Board of Trustees of the Trust supervises each Fund's
activities, monitors its contractual arrangements with various service providers
and decides upon matters of general policy.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds. The holding company of Wells Fargo Bank, the investment advisor to
the Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998. Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one or more Stagecoach
and/or Norwest Advantage Funds. One of these predecessor funds is expected to
be the "accounting survivor," which means that its performance and financial
statement history will be assumed by the Wells Fargo Funds Trust Fund. The
succession transactions are conditioned on shareholder approval by the
shareholders of the various Stagecoach and Norwest Advantage Funds. The Table
on page __ identifies the expected accounting survivors.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund class paid on an annual basis for the
services described.

The Sub-Advisor
Wells Capital Management ("WCM"), a wholly owned subsidiary of Wells Fargo Bank,
N.A., is the sub-advisor for the Funds. In this capacity, it is responsible for
the day-to-day investment management activities of the Funds. As of December
31, 1998, WCM provided advisory services for over $39 billion in assets.

The Administrator
Wells Fargo Bank provides the Funds with administration services, including
general supervision of each Fund's operation, coordination of the other services
provided to each Fund, compilation of information for reports to the SEC and the
state securities commissions, preparation of proxy statements and shareholder
reports, and general supervision of data compilation in connection with
preparing periodic reports to the Trust's Trustees and officers. Wells Fargo
Bank also furnishes office space and certain facilities to conduct each Fund's
business. For providing these services, Wells Fargo Bank is entitled to receive
a fee of .15% of the average annual net assets of each Fund.

Shareholder Servicing Plan
We have a shareholder servicing plan for each Fund. Under this plan, we have
engaged various shareholder servicing agents to process purchase and redemption
requests, to service shareholder accounts, and to provide other related
services. For these services, each Fund pays up to 0.25% of its average annual
net assets (except that the Class O shares of the Equity Index Fund pays up to
0.20% of its average annual net assets).

                                       34

A Choice of Share Classes
After choosing a Fund, your next most important choice is which share class to
buy.  The following classes of shares are available through this Prospectus:
 .  Class A Shares - with a front-end sales charge, volume reductions and lower
   on-going expenses than Class B and Class C shares.
 .  Class B Shares - with a contingent deferred sales charge ("CDSC") payable
   upon redemption that diminishes over time, and higher on-going expenses than
   Class A shares.
 .  Class C Shares - with a 1.00% CDSC on redemptions made within one year of
   purchase, and higher on-going expenses than Class A shares.
 .  Class O Shares - have no front-end and contingent deferred sales charges

The choice between share classes is largely a matter of preference. You should
consider, among other things, the different fees and sales loads assessed on
each share class and the length of time you anticipate holding your investment.
If you prefer to pay sales charges up front, wish to avoid higher on-going
expenses, or, more importantly, you think you may qualify for volume discounts
based on the amount of your investment, then Class A shares may be the choice
for you.

You may prefer to see "every dollar working" from the moment you invest. If so,
then consider Class B or Class C shares. Please note that Class B shares
convert to Class A shares after seven years to avoid the higher on-going
expenses assessed against Class B shares.

Class C shares are available for the Diversified Equity, Equity Value, Growth
Equity, International Equity and Large Company Growth Funds.  They are similar
to Class B shares, with some important differences. Unlike Class B hares, Class
C shares do not convert to Class A shares. The higher on-going expenses will be
assessed as long as you hold the shares. The choice between Class B and Class C
shares may depend on how long you intend to hold Fund shares before redeeming
them.

[The Class O shares of the Equity Index Fund is intended for on-line investors.
If you prefer to pay no sales charges and consent to receive all information
about the Fund electronically, then Class O shares might be the choice for you.]

Please see the expenses listed for each Fund and the following sales charge
schedules before making your decision. You should also review the "Reduced
Sales Charges" section of the Prospectus. You may wish to discuss this choice
with your financial consultant.

Class A Share Sales Charge Schedule
If you choose to buy Class A shares, you will pay the Public Offering Price
(POP) which is the Net Asset Value (NAV) plus the applicable sales charge. The
money market funds listed in this prospectus do not impose sales charges on the
purchase of Class A shares. Since sales charges are reduced for Class A share
purchases above certain dollar amounts, known as "breakpoint levels", the POP is
lower for these purchases.

/1/We will assess Class A shares purchases of $1,000,000 or more a 1.00% CDSC if
they are redeemed within one year from the date of purchase. Charges are based
on the lower of the NAV on the date of purchase or the date of redemption.

Class B Share CDSC Schedule
If you choose Class B shares, you buy them at NAV and agree that if you redeem
your shares within six years of the purchase date, you will pay a CDSC based on
how long you have held your shares.  Certain exceptions apply (see "Class B and
Class C Share CDSC Reductions" and "Waivers for Certain Parties").  The CDSC
schedule is as follows:

- -----------------------------------------------------------------------------------------------------
</TABLE>

The CDSC percentage you pay is based on the lower of the NAV of the shares
on the date of the original purchase, or the NAV of the shares on the date of
redemption.

We always process partial redemptions so that the least expensive shares are
redeemed first in order to reduce your sales charges.  After shares are held for
six years, the CDSC expires.  After shares are held for seven years, the Class B
shares are converted to Class A shares to reduce your future on-going expenses.

Class B shares received in the reorganization of the Stagecoach Funds are
subject to the above CDSC schedule based on the purchase date(s) of the
Stagecoach shares, and such shares convert to Class A shares automatically after
six years.

Class B shares received in the reorganization of the Stagecoach Funds in
exchange for Stagecoach Fund shares that were purchased prior to March 3, 1997
are subject to a CDSC if they are redeemed within four years of the original
purchase.  The CDSC Schedule for these shares is below:

</TABLE>

The above-described schedules for shares of the former Stagecoach Funds and
Norwest Advantage Funds do not apply for any new shares purchased. If you
exchange the Class B shares received in the reorganization for Class B shares of
another Fund, you will retain these CDSC schedules on your exchanged shares.
Additional shares purchased will age at the higher CDSC schedule.

Class C Share CDSC Schedule
If you choose Class C shares, you buy them at NAV and agree that if you redeem
your shares within one year of the purchase date, you will pay a CDSC of 1.00%.

The CDSC percentage you pay is based on the lower of the NAV on the date of the
original purchase, or the NAV on the date of redemption. The distributor pays
sales commissions of up to 1.00% of the purchase price of Class C shares to
selling agents at the time of the sale, and up to 1.00% annually thereafter.

We always process partial redemptions so that the least expensive shares are
redeemed first in order to reduce your sales charges. Class C shares do not
convert to Class A shares, and therefore continue to pay the higher on-going
expenses.

Reduced Sales Charges
Generally, we offer more sales charge reductions for Class A shares than for
Class B and Class C shares, particularly if you intend to invest greater
amounts.  You should consider whether you are eligible for any of the potential
reductions when you are deciding which share class to buy.

Class A Share Reductions:  [PLEASE CONFIRM]

 .    You pay no sales charges on Fund shares you buy with reinvested
     distributions.
 .    You pay a lower sales charge if you are investing an amount over a
     breakpoint level. See the "Class A Share Sales Charge Schedule" above.
 .    By signing a Letter of Intent (LOI), you pay a lower sales charge now in
     exchange for promising to invest an amount over a specified breakpoint
     within the next 13 months. We will hold in escrow shares equal to
     approximately 5% of the amount you intend to buy. If you do not invest the
     amount specified in the LOI before the expiration date, we will redeem
     enough escrowed shares to pay the difference between the reduced sales load
     you paid and the sales load you should have paid. Otherwise, we will
     release the escrowed shares when you have invested the agreed amount.
 .    Rights of Accumulation (ROA) allow you to combine the amount you invest
     with the total NAV of shares you own in other Wells Fargo front-end load
     Funds in order to reach breakpoint levels for a reduced load. We give you a
     discount on the entire amount of the investment that puts you over the
     breakpoint level.
 .    If you are reinvesting the proceeds of a Wells Fargo Fund redemption for
     shares on which you have already paid a front-end sales charge, you have
     [120] days to reinvest the proceeds of that redemption with no sales charge
     into a Fund that charges the same or a lower front-end sales charge. If you
     use such a redemption to purchase shares of a Fund with a higher front-end
     sales charge, you will have to pay the difference between the lower and
     higher charge.
 .    You may reinvest into a Wells Fargo Fund with no sales charge a required
     distribution from a pension, retirement, benefits, or similar plan for
     which Wells Fargo Bank acts as trustee provided the distribution occurred
     within the 30 days prior to your reinvestment.

If you believe you are eligible for any of these reductions, it is up to you to
ask the selling agent or the shareholder servicing agent for the reduction and
to provide appropriate proof of eligibility.

You, or your fiduciary or trustee, may also tell us to extend volume discounts,
including the reductions offered for rights of accumulation and letters of
intent, to include purchases made by:

 .    a family unit, consisting of a husband and wife and children under the age
     of twenty-one or single trust estate;
 .    a trustee or fiduciary purchasing for a single fiduciary relationship; or
 .    the members of a "qualified group" which consists of a "company" (as
     defined in the Investment Company Act of 1940 ("1940 Act")), and related
     parties of such a "Company," which has been in existence for at least six
     months and which has a primary purpose other than acquiring Fund shares at
     a discount.

How a Letter of Intent Can Save You Money!
If you plan to invest, for example, $100,000 in a Wells Fargo Fund in
installments over the next year, by signing a letter of intent you would pay
only 3.75% sales load on the entire purchase.  Otherwise, you might pay 5.75% on
the first $49,999, then 4.75% on the next $50,000!

Class B and Class C Share CDSC Reductions:
 .    You pay no CDSC on Funds shares you purchase with reinvested distributions.
 .    [We waive the CDSC for all redemptions made because of scheduled or
     mandatory distributions for certain retirement plans.] (See your retirement
     plan disclosure for details.)

                                       38

Reduced Sales Charges (Cont'd)

 .    We waive the CDSC for redemptions made in the event of the shareholder's
     death or for a disability suffered after purchasing shares. ("Disability"
     is defined by the Internal Revenue Code of 1986.)
 .    We waive the CDSC for redemptions made at the direction of Wells Fargo in
     order to, for example, complete a merger or close an account whose value
     has fallen below the minimum balance.
 .    We waive Class C share CDSC for certain types of accounts.

For Class B shares purchased [outside of an IRA] or other qualified plan after
May 18, 1999 for former Norwest Advantage Fund shareholders, after July 17, 1999
for former Stagecoach Funds shareholders, or after September 17, 1999, for all
other shareholders, no CDSC is imposed on withdrawals that meet all of the
following circumstances:
 .    withdrawals are made by participating in the Systematic Withdrawal Plan;
 .    withdrawals may not exceed 10% of your fund assets annually based on your
     anniversary date in the Systematic Withdrawal Plan; and
 .    you must participate in the dividend and capital gain reinvestment program.

Waiver for Certain Parties
If you are eligible for certain waivers, we will sell you Class A shares so you
can avoid higher on-going expenses.  The following people can buy Class A shares
at NAV:
 .  Current and retired employees, directors and officers of:
   .    Wells Fargo Funds and its affiliates;
   .    Wells Fargo Bank, Norwest Bank and their affiliates;
   .    Stephens and its affiliates; and
   .    Broker-Dealers who act as selling agents.
 .  [The spouses of any of the above, as well as the grandparents, parents,
   siblings, children, grandchildren, aunts, uncles, nieces, nephews, fathers-
   in-law, mothers-in-law, brothers-in-law and sisters-in-law of either the
   spouse or the current or retired employee, director of officer.]

You may also buy Class A Fund shares at NAV if they are to be included in
certain retirement, benefits, pension or investment "wrap accounts" with whom
Wells Fargo has reached an agreement, or through an omnibus account maintained
with a Fund by a broker/dealer.

We reserve the right to enter into agreements that reduce or eliminate sales
charges for groups or classes of shareholders, or for Fund shares included in
other investment plans such as "wrap accounts."  If you own Fund shares as part
of another account or package such as an IRA or a sweep account, you must read
the directions for that account.  These directions may supersede the terms and
conditions discussed here.

Distribution Plan
We have adopted Distribution Plans pursuant to Rule 12b-1 for the Class B and
Class C shares of the Funds.  The plans authorize the payment of all or part of
the cost of preparing and distributing prospectuses and distribution-related
services including ongoing compensation to selling agents.  The Plan also
provides that, if and to the extent any shareholder servicing payments are
recharacterized as payments for distribution-related services, they are approved
and payable under the distribution plan.  The fees paid under these plans are as
follows:

These fees are paid out of the Funds' assets on an on-going basis.  Overtime,
these fees will increase the cost of your investment and may cost you more than
paying other types of sales charges.

Exchanges

Exchanges between Wells Fargo Funds are two transactions:  a sale of shares of
one Fund and the purchase of shares of another.  In general, the same rules and
procedures that apply to sales and purchases apply to exchanges.  There are,
however, additional factors you should keep in mind while making or considering
an exchange:

 .    You should carefully read the Prospectus for the Fund into which you wish
     to exchange.
 .    Every exchange involves selling Fund shares and that sale may produce a
     capital gain or loss for federal income tax purposes.
 .    If you are making an initial investment into a new Fund through an
     exchange, you must exchange at least the minimum first purchase amount of
     the Fund you are redeeming, unless your balance has fallen below that
     amount due to market conditions.
 .    Any exchange between Funds you already own must meet the minimum redemption
     and subsequent purchase amounts for the Funds involved.
 .    Exchanges between Class B shares and the Wells Fargo Money Market Fund
     Class B shares will not trigger the CDSC. The new shares will continue to
     age according to their original schedule while in the new Fund and will be
     charged the CDSC applicable to the original shares upon redemption.
     Exchanges into Money Market Fund Class B shares are subject to certain
     restrictions in addition to those described above.
 .    Exchanges from any share class to a money market fund can only be re-
     exchanged for the original share class.
 .    In order to discourage excessive Fund transaction expenses that must be
     borne by other shareholders, we reserve the right to limit or reject
     exchange orders. Generally, we will notify you 60 days in advance of any
     changes in your exchange privileges.
 .    You may make exchanges between like share classes. You may also exchange
     from Class A or Class C shares to any non-institutional money market fund.

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:

 .    As with all mutual fund investments, the price you pay to purchase shares
     or the price you receive when you redeem shares is not determined until
     after a request has been received in proper form.
 .    We determine the Net Asset Value ("NAV") of each class of the Funds' shares
     each business day as of the close of regular trading on the NYSE. We
     determine the NAV by subtracting the Fund class's liabilities from its
     total assets, and then dividing the result by the total number of
     outstanding shares of that class. Each Fund's assets are generally valued
     at current market prices. See the Statement of Additional Information for
     further disclosure.
 .    We process requests to buy or sell shares of the funds each business day as
     of the close of regular trading on the New York Stock Exchange ("NYSE"),
     which is usually 1:00 p.m. (Pacific time)/3:00 p.m. (Central time). If the
     markets close early, the Funds may close early and may value their shares
     at earlier times under these circumstances. Any request we receive in
     proper form before these times is processed the same day. Requests we
     receive after the cutoff times are processed the next business day.
 .    The funds are open for business on each day the NYSE is open for business.
     NYSE holidays include New Year's Day, Martin Luther King, Jr. Day,
     President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
     Thanksgiving Day and Christmas Day. When any holiday falls on a weekend,
     the NYSE typically is closed on the weekday immediately before or after
     such holiday.

You can buy Fund shares:
 .    By opening an account directly with the Fund (simply complete and return a
     Wells Fargo Funds Trust application with proper payment);
 .    Through a brokerage account with an approved selling agent; or
 .    Through certain retirement, benefits and pension plans, or through certain
     packaged investment products (please see the providers of the plan for
     instructions).

Minimum Investments:
 .    $1,000 per Fund minimum initial investment;/1/ or
 .    $100 per Fund if you use the Systematic Purchase Program; and
 .    $100 per Fund for all investments after your first.

/1/  [Purchases of Class B shares in amounts of $250,000 or more require the
     prior approval of your selling agent.]

We may waive the minimum for Funds you purchase through certain retirement,
benefit and pension plans, through certain packaged investment products, or for
certain classes of shareholders as permitted by the SEC.  Check the specific
disclosure statements and applications for the program through which you intend
to invest.

 Telephone privileges are automatically made available to you
 unless you specifically decline them on your application or
 subsequently in writing.
- -----------------------------------------------------------------
 Phone privileges allow us to accept transaction instructions by
 anyone representing themselves as the shareholder and who

 We will not be liable for any losses incurred if we follow
 telephone instructions we reasonably believe to be genuine.

 account was changed by phone in the last 15 days.

 GENERAL NOTES FOR SELLING SHARES
- ------------------------------------------------------------------------------
 We determine the NAV of the Funds each day as of the close of regular trading
 on the NYSE, which is generally 1:00 PM (Pacific time)/3:00 P.M. (Central
 time). If any of the markets for the Funds close early, the Funds may close
 early, and may value their shares at earlier times under these circumstances.
- ------------------------------------------------------------------------------
 Your redemptions are net of any applicable CDSC.
- ------------------------------------------------------------------------------
 We will process requests to sell shares at the first NAV calculated after a
 request in proper form is received. Requests received before the cutoff times
 are processed on the same business day.
- ------------------------------------------------------------------------------
 If your purchased shares through a packaged investment product or retirement
 plan, read the directions for selling shares provided by the product or plan.
 There maybe special requirements that supersede the directions in this
 Prospectus.
- ------------------------------------------------------------------------------
 We reserve the right to delay payment of a redemption so that we may be
 reasonably certain that investments made by check or Systematic Purchase Plan
 have been collected. Payments of redemptions also may be delayed under
 extraordinary circumstances or as permitted by the SEC in order to protect
 remaining shareholders.
- ------------------------------------------------------------------------------
 Generally, we pay redemption requests in cash, unless the redemption request is
 for more than $250,000 or 1% of the net assets of the Fund by a single
 shareholder over any ninety-day period. If a request for a redemption is over
 these limits, it may be to the detriment of existing shareholders to pay such
 redemption in cash. Therefore, we may pay all or part of the redemption in
 securities of equal value.

 Additional Services and Other Information

 Automatic Programs:
These programs help you conveniently purchase and/or redeem shares each month.
Call Investor Services 1-800-222-8222 for more information.

 .  Systematic Purchase Plan - With this program, you can regularly purchase
   shares of a Wells Fargo Fund with money automatically transferred from a
   linked bank account. Simply select the Fund you would like to purchase,
   specify an amount of at least $100, and tell us the day of the month you
   would like the money invested. If you do not specify a date, we will transfer
   the money and invest in shares of the Fund you select on or about the 25th
   day of the month.

 .  Systematic Exchange Plan - With this program, you can regularly exchange
   shares of a Wells Fargo Fund you own for shares of another Wells Fargo Fund.
   The exchange amount must be at least $100, and the exchange will take place
   on or about the 25th of each month. See the "Exchanges" section of this
   prospectus for the conditions that apply to your shares. This feature may not
   be available for certain types of accounts.

 .  Systematic Withdrawal Plan - With this program, you can regularly redeem
   shares and receive the proceeds by check or by transfer to a linked bank
   account. Simply specify an amount of at least $100 and we will sell your
   shares equal to that amount on or about the 25th of each month. To
   participate in this program, you:
      .  must have a Fund account value at $10,000 or more;
      .  must have your distributions reinvested; and
      .  may not simultaneously participate in the Systematic Purchase Plan.

It generally takes about ten days to establish a plan once we have received your
instructions.  It generally takes about five days to change or cancel
participation in a plan.  We automatically cancel your program if the linked
bank account your specified is closed.

Dividend and Capital Gain Distributions Options
The Funds in this Prospectus pay dividends periodically and make capital gains
distributions annually.  The Funds pay any dividends quarterly.

We offer the following distribution options:

 .  Automatic Reinvestment Option - Lets you buy new shares of the same class of
   the Fund that generated the distributions. The new shares are purchased at
   NAV generally on the day the income is paid. This option is automatically
   assigned to your account unless you specify another plan.

 .  Check Payment Option - Allows you to receive checks for distributions mailed
   to your address of record or to another name and address which you have
   specified in written, signature guaranteed instructions.  If checks remain
   uncashed for six months or are undeliverable by the Post Office, we will
   reinvest the distributions at the earliest date possible.

Two Things to Keep In Mind About Distributions
Remember, distributions have the effect of reducing the NAV per share by the
amount distributed.  Also, distributions on new shares shortly after purchase
would be in effect a return of capital, although the distribution may still be
taxable to you.

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus.  The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder.  It
is not intended as a substitute for careful tax planning.  You should consult
your tax advisor about your specific tax situation.  Federal income tax
considerations are discussed further in the Statement of Additional Information.

Dividends distributed from the Funds attributable to their income from other
investments and net short-term capital gain (generally, the excess of net short-
term capital gains over net long-term capital losses) will be taxable to you as
ordinary income.  Corporate shareholders may be able to deduct a portion of
their dividends when determining their taxable income.

We will pass on to you any net capital gain (generally the excess of net long-
term capital gains over net short-term capital losses) earned by a Fund as a
capital gain distribution.  In general, these distributions will be taxable to
you as long-term capital gains which may qualify for taxation at preferential
rates in the hands of non-corporate shareholders.  Any distribution that is not
from net investment income, short term capital gains, or net capital gain may be
characterized as a return of capital to shareholders.

                             TABLE OF PREDECESSORS

                 WELLS FARGO FUNDS TRUST EQUITY FUNDS OVERVIEW

Diversified Equity Fund

Objective
Seeks long-term capital appreciation while moderating annual return volatility.

Principal Strategy
We invest in five separate equity portfolios with the following styles: index,
income equity, large company, diversified small cap and international. This
"multi-style" approach is designed to minimize the volatility and risk of
investing in a single investment style.

companies.

average potential for growth.

Diversified Small Cap Fund

Objective
Seeks long-term capital appreciation while moderating annual return volatility.

Principal Strategy
We invest in several (currently 5) styles of small capitalization equity
portfolios. This "multi-style" approach is designed to minimize the volatility
and risks of investing in small capitalization equity securities.

Equity Value Fund

Objective
Seeks to provide investors with above-average capital appreciation.

Principal Strategy
We invest in equity securities that we believe are undervalued in relation to
the overall stock markets. Dividends are a secondary consideration when
selecting stocks.

<PAGE>

Index Fund

Objective
Seeks to replicate the return of the S&P 500 Index.

Principal Strategy
We invest in substantially all of common stocks listed in the S&P 500 Index,
and attempt to achieve at least a 95% correlation between the performance of the
S&P 500 Index and our investment results before expenses, regardless of market
conditions.

International Equity Fund

Objective
Seeks to earn total return, with an emphasis on capital appreciation, over the
long-term.

Principal Strategy
We invest in equity securities of companies located or operating in developed
foreign countries and emerging markets of the world. We apply a fundamentals-
driven, value-oriented analysis to identify companies that we believe have
above-average potential for long-term growth.

International Fund

Objective
Seeks long-term capital appreciation.

Principal Strategy
We invest in two separate portfolios, an international equity portfolio
investing largely in the common stock of high-quality companies based outside of
the United States, and an international emerging markets portfolio. This "multi-
style" approach is designed to minimize the volatility and risk associated with
investing in the individual international portfolios.

Large Company Growth Fund

Objective
Seeks long-term capital appreciation.

Principal Strategy
We invest in the common stocks of large, high-quality domestic companies whose
market capitalization is greater than the median of the Russell 1000 index,
currently about $3.7 billion, with superior growth potential.

Small Cap Opportunities Fund

Objective
Seeks long-term capital appreciation.

We invest in equity securities of small domestic companies that at the time of
purchase have market captializations of $1.5 billion or less. We look for
companies with above-average growth.

Objective
Seeks capital appreciation by investing primarily in common stocks of smaller
companies.

Principal Strategy
We invest in the common stocks of companies listed on the Russell 2000 index,

Summary Of Important Risks

 This section summarizes important risks that are common to all of the Funds
 described in this Prospectus, and important risks that relate specifically to
 particular Funds.  Both are important to your investment choice.  Additional
 information about these and other risks is included in the individual Fund
 descriptions later in this Prospectus, under General Investment Risks beginning
 on page __ and in the Funds' Statement of Additional Information.  An
 investment in a Fund is not a deposit of Wells Fargo Bank and is not insured or
 guaranteed by the Federal Deposit Insurance Corporation or any other government
 agency.

 Common Risks for the Funds

 Equity Securities.  The Funds invest in equity securities, which are subject to
 equity market risk.  This is the risk that stock prices will fluctuate and can
 decline and reduce the value of a Fund's portfolio.  Certain types of stock and
 certain individual stocks selected for a Fund's portfolio may underperform or
 decline in value more than the overall market.  As of the date of this
 Prospectus, the equity markets, as measured by the S&P 500 Index and other
 commonly used indexes, are trading at or close to record levels.  There can be
 no guarantee that these levels will continue.  The Funds that invest in smaller
 companies, in foreign companies (including investments made through American
 Depositary Receipts and similar instruments), and in emerging markets are
 subject to additional risks, including less liquidity and greater price
 volatility.  A Fund's investment in foreign companies and emerging markets are
 also subject to special risks associated with international investing,
 including currency, political, regulatory and diplomatic risks.

 Debt Securities.  The Funds may invest some of their assets in debt securities,
 such as notes and bonds, which are subject to credit risk and interest rate
 risk.  Credit risk is the possibility that an issuer of an instrument will be
 unable to make interest payments or repay principal.  Changes in the financial
 strength of an issuer or changes in the credit rating of a security may affect
 its value.  Interest rate risk is the risk that interest rates may increase,
 which will reduce the resale value of instruments in a Fund's investments,
 including U.S. Government obligations.  Debt securities with longer maturities
 are generally more sensitive to interest rate changes than those with shorter
 maturities.  Changes in market interest rates do not affect the rate payable on
 debt instruments held in a Fund, unless the instrument has adjustable or
 variable rate features, which can reduce interest rate risk.  Changes in market
 interest rates may also extend or shorten the duration of certain types of
 instruments, such as asset-backed securities, thereby affecting their value and
 the return on your investment.

Fund-Specific Risks

 Diversified Equity Fund
 Stocks selected for their high dividend yields may be more sensitive to
 interest rate changes than other stocks.  Also, stocks of the smaller and
 medium-sized companies purchased for this Fund may be more volatile and less
 liquid than larger company stocks.

 Disciplined Growth Fund
 The Fund is primarily subject to the equity market risks described in the
 Common Risks section above.  The advisor selects growth stocks based on
 prospects for future earnings, which may not grow as expected. In addition, at
 times, the overall market or the market for value stocks may outperform growth
 stocks. Dividend-producing large company stocks have experienced unprecedented
 appreciation in recent years. There is no guarantee such performance levels
 will continue.

 Diversified Small Cap Fund
 Stocks of smaller companies purchased for this Fund may be more volatile and
 less liquid than larger company stocks.

                                       7
<PAGE>

 Equity Value Fund
 There is no guarantee that securities selected as "under-valued" will perform
 as expected.  Stocks of smaller, medium-sized and foreign companies purchased
 using the value strategy may be more volatile and less liquid than other
 comparable securities.

 Growth Equity Fund
 The Fund is primarily subject to the equity market risks described in the
 Common Risks section above. The advisor selects growth stocks based on
 prospects for future earnings, which may not grow as expected. In addition, at
 times, the overall market or the market for value stocks may outperform growth
 stocks.

 Index Fund
 We attempt to match as closely as possible the performance of the S&P 500
 Index.  Therefore, during periods when the S&P 500 Index is losing value, your
 investment will also lose value.

 International Equity Fund
 Foreign company stocks involve special risks, including generally higher
 commission rates, political, social and monetary or diplomatic developments
 that could effect U.S. investments in foreign countries.  Emerging market
 countries may experience increased political instability, and are often
 dependent on international trade, making them more vulnerable to events in
 other countries.  They may have less developed financial systems and volatile
 currencies and may be more sensitive than more mature markets to a variety of
 economic factors.  Emerging market securities may also be less liquid than
 securities of more developed countries, which may make them more difficult to
 sell, particularly during a market downturn.  Additionally, dispositions of
 foreign securities and dividends and interest payable on those securities may
 be subject to foreign taxes.

 International Fund
 Foreign company stocks involve special risks, including generally higher
 commission rates, political, social and monetary or diplomatic developments
 that could effect U.S. investments in foreign countries.  Additionally,
 dispositions of foreign securities and dividends and interest payable on those
 securities may be subject to foreign taxes.

 Large Company Growth Fund
 The Fund is primarily subject to the equity market risks described in the
 Common Risks section above.  The advisor selects growth stocks based on
 prospects for future earnings, which may not grow as expected. In addition, at
 times, the overall market or the market for value stocks may outperform growth
 stocks. Dividend-producing large company stocks have experienced unprecedented
 appreciation in recent years. There is no guarantee such performance levels
 will continue.

 Small Cap Opportunities Fund
 There is no guarantee that securities selected as "under-valued" will perform
 as expected.  Stocks of smaller, medium-sized and foreign companies purchased
 using the value strategy may be more volatile and less liquid than other
 comparable securities.

 Small Cap Value Fund
 Stocks of smaller companies purchased for this Fund may be more volatile and
 less liquid than larger company stocks.

 Small Company Growth Fund
 Stocks of the smaller and medium-sized companies purchased for this Fund may be
 more volatile and less liquid than larger company stocks. The advisor selects
 growth stocks based on prospects for future earnings, which may not grow as
 expected. In addition, at times, the overall market or the market for value
 stocks may outperform growth stocks.

 Performance History
 The Funds in this prospectus will commence operations in September 1999.  No
 performance information is given for the Funds because they will have been in
 operation for less than one year.

Diversified Equity Fund

Investment Objective
The Diversified Equity Fund's investment objective is to provide long-term
capital appreciation with moderate annual return volatility by diversifying its
investments among different equity investment styles.

Investment Policies
The Fund invests in a "multi-style" approach designed to minimize the volatility
and risk of investing in a single investment style.  The Fund currently invests
in 11 Portfolios.

Permitted Investments
The Fund's investments combine 5 different equity investment styles -- an index
style, an income equity style, a large company style, a diversified small cap
style, and an international style.  The Fund allocates the assets dedicated to
large company investments to 2 Portfolios, the assets allocated to small company
investments to 5 Portfolios, and the assets dedicated to international
investments to 2 Portfolios.  Because Diversified Equity Fund blends 5 equity
investment styles, it is anticipated that is price and return volatility will be
less than that of Growth Equity Fund, which blends 3 equity investment styles.

Important Risk Factors
Stocks of foreign companies purchased by this Fund may be subject to political
and economic instability.  Also, stocks of the smaller and medium-sized
companies purchased for this Fund may be more volatile and less liquid than
larger company stocks.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure.  In this structure,
the "gateway" Diversified Equity Fund invests all of its assets in various
"core" portfolios whose objectives and investment policies are consistent with
the Fund's investment objective.  Gateway funds investing in various core
portfolios can enhance their investment opportunities and reduce their expenses
through sharing the costs of managing a large pool of assets.  References to the
investment activities of the Fund also refer to the investments of the core
portfolios in which it invests.

Disciplined Growth Fund

Investment Objective
The Disciplined Growth Fund seeks capital appreciation by investing primarily in
common stocks of larger companies.

Investment Policies
The Fund seeks higher long-term returns by investing primarily in the common
stock of companies that, in the view of the Advisor, possess above average
potential for growth.  The Fund invests in companies with average market
capitalizations greater than $5 billion.

Permitted Investments
The Fund seeks to identify growth companies that will report a level of
corporate earnings that exceed the level expected by investors.  In seeking
these companies, the Advisor uses both quantitative and fundamental analysis.
The Advisor may consider, among other factors, changes of earnings estimates by
investment analysts, the recent trend of company earnings reports, and an
analysis of the fundamental business outlook for the company.  The Advisor uses
a variety of valuation measures to determine whether or not the share price
already reflects any positive fundamentals identified by the Advisor.  In
addition to approximately equal weighting of portfolio securities, the Adviser
attempts to constrain the variability of the investment returns by employing
risk control screens for price volatility, financial quality, and valuation.

Important Risk Factors
This Fund is primarily subject to the equity market risks described in the
Common Risks section.

You should consider the Summary of Important Risks on page ___, the General
Investment Risks beginning on page ___, and the specific risks listed above.
They are all important to your investment choice.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure.  In this structure,
the "gateway" Disciplined Growth Fund invests all of its assets in a "core"
portfolio that has a substantially identical investment objective and
substantially similar policies as the gateway fund.  Gateway funds investing in
the same core portfolio can enhance their investment opportunities and reduce
their expense ratios through sharing the costs of managing a large pool of
assets.  References to the investment activities of the Fund also refer to the
investment activities of the core portfolio.

Diversified Small Cap Fund

Investment Objective
The Diversified Small Cap Fund's investment objective is to provide long-term
capital appreciation with moderate annual return volatility by diversifying its
investments across different small capitalization equity investment styles.

Investment Policies
The Fund invests in a "multi-style" approach designed to minimize the volatility
and risk of investing in small capitalization equity securities.

Permitted Investments
The Fund invests in several different small capitalization equity styles in
order to reduce the risk of price and return volatility associated with reliance
on a single investment style. The Fund currently invests in 5 Portfolios.

Important Risk Factors
Stocks of smaller companies purchased for the Fund may be more volatile and less
liquid than larger company stocks. Also, short term changes in the demand for
the securities of smaller companies may have a disproportionate effect on their
market price, tending to make the prices of these securities fall more in
response to selling pressure.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure. In this structure,

Equity Value Fund

Investment Objective
The Equity Value Fund seeks to provide investors with long-term capital
appreciation.

Investment Policies
We seek long-term capital appreciation by investing in a diversified portfolio
composed primarily of equity securities that are trading at low price-to-
earnings ratios, as measured against the stock market as a whole or against the
individual stock's own price history. In addition we look at the price-to-book
value and price-to-cash flow ratios of companies for indications of attractive
valuation. We use both quantitative and qualitative analysis to identify
possible investments. Dividends are a secondary consideration when selecting
stocks. We may purchase particular stocks when we believe that a history of
strong dividends may increase their market value.

Permitted Investments
Under normal market conditions, we invest:

 .  primarily in common stocks of both large, well-established companies and
   smaller companies with market capitalization exceeding $50 million at the
   time of purchase;

 .  in debt instruments that may be converted into the common stock of both U.S.
   and foreign companies; and

 .  up to 25% of our assets in foreign companies through American Depositary
   Receipts and similar instruments.

We may also purchase convertible debt securities with the same characteristics
as common stock, as well as in preferred stock and warrants. We may temporarily
hold assets in cash or in money market instruments, including U.S. Government
obligations, shares of other mutual funds and repurchase agreements, or make
short-term investments, either to maintain liquidity or for short-term defensive
purposes when we believe it is in the best interests of shareholders. During
such periods, the Fund may not achieve its objective of long term capital
appreciation.

Important Risk Factors
There is no guarantee that securities selected as "undervalued" will perform as
expected. Stocks of smaller, medium-sized and foreign companies purchased using
the value approach may be more volatile and less liquid than other comparable
securities.

Investment Risks beginning on page __, and the specific risks listed above.

Growth Equity Fund

Investment Objective
The Growth Equity Fund's investment objective is to provide a high level of
long-term capital appreciation with moderate annual return volatility by
diversifying its investments among different equity investment styles.

Investment Policies
The Fund invests in a "multi-style" approach designed to reduce the volatility
and risk of investing in a single equity style. The Fund currently invests in 8
Portfolios.

Permitted Investments
The Fund's investments combine 3 different equity styles -- a large company
growth style, a diversified small cap style, and an international style. The
Fund allocates the assets dedicated to small company investments to 5 Portfolios
and the assets dedicated to international investments to 2 Portfolios. It is
anticipated that the Fund's price and return volatility will be somewhat greater
than those of Diversified Equity Fund, which blends 5 equity styles.

Important Risk Factors
This Fund is primarily subject to the equity market risks described in the
Common Risks section.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.

Index Fund

Investment Objective
The Index Fund seeks to replicate the total rate of return of the Standard &
Poor's 500 Composite Stock Index (the "S&P 500 Index").

Investment Policies
We invest in substantially all of the common stocks listed on the S&P 500 Index
and attempt to achieve a 95% correlation between the performance of the S&P 500
Index and our investment results, before expenses. This correlation is sought
regardless of market conditions.

A precise duplication of the performance of the S&P 500 Index would mean that
the net asset value of Fund shares, including dividends and capital gains would
increase or decrease in exact proportion to changes in the S&P 500 Index. Such a
100% correlation is not feasible. Our ability to track the performance of the
S&P 500 Index may be affected by, among other things, transaction costs and
shareholder purchases and redemptions. We will regularly monitor the performance
and composition of the S&P 500 Index, adjust the Fund's portfolio as necessary
in order to achieve the 95% correlation.

Permitted Investments
Under normal market conditions, we invest:

 .  in a diversified portfolio of common stocks designed to provide a relative
   sample of the stocks listed on the S&P 500 Index;
 .  in stock index futures and options on stock indexes as a substitute for
   comparable position in the underlying securities; and
 .  in interest-rate futures contracts, options or interest rate swaps and index
   swaps.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, either to maintain liquidity
or for short-term defensive purposes when we believe it is in the best interests
of shareholders to do so. During such periods, the Fund may not achieve its
objective.

Important Risk Factors
We attempt to replicate the performance of the S&P 500 Index. Therefore, during
periods when the S&P 500 Index is losing value, your investment will also lose
value.

Investment Risks beginning on page __, and the specific risks listed above.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure. In this structure,
the "gateway" Index Fund invests all of its assets in a "core" portfolio that
has a substantially identical investment objective and substantially similar
polices as the gateway fund. Gateway funds investing in the same core portfolio
can enhance their investment opportunities and reduce their expense ratios
through sharing the costs of managing a large pool of assets. References to the
investment activities of the Fund also refer to the investment activities of the
core portfolio.

International Equity Fund

Investment Objective
The International Equity Fund seeks to earn total return, with an emphasis on
capital appreciation, over the long-term, by investing primarily in equity
securities of non-U.S. companies.

Investment Policies
We actively manage a diversified portfolio of equity securities of companies
located or operating in developed non-U.S. countries and in emerging markets of
the world. We expect that the securities we hold will be traded on a stock
exchange or other market in the country in which the issuer is based, but they
also may be traded in other countries, including the U.S.

We apply a fundamentals-driven, value-oriented analysis to identify companies
with above-average potential for long-term growth. The financial data we examine
includes both the company's historical performance results and its projected
future earnings. Among other key criteria we consider are a company's local,
regional or global franchise; history of effective management demonstrated by
expanding revenues and earnings growth; prudent financial and accounting
policies and ability to take advantage of a changing business environment.

Permitted Investments
Under normal market conditions, we invest:

 .  at least 80% of our assets in equity securities of companies located or
   operating outside the U.S.;
 .  in a minimum of five countries exclusive of the U.S.;
 .  up to 50% of our assets in any one country;
 .  up to 25% of our portfolio in emerging markets;
 .  in issuers with an average market capitalization of $10 billion or more,
   although we may invest in equity securities of issuers with market
   capitalization as low as $250 million; and
 .  in equity securities including common stocks, and preferred stocks, and in
   warrants, convertible debt securities, ADRs, GDRs (and similar instruments)
   and shares of other mutual funds.

Although it is not our intention to do so, we reserve the right to hedge the
portfolio's foreign currency exposure by purchasing or selling foreign currency
futures and forward foreign currency contracts.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, either to maintain liquidity
or for short-term defensive purposes when we believe it is in the best interests
of shareholders to do so. We may also, for defensive purposes, invest without
limit in cash, short-term debt and equity securities of U.S. companies when we
believe it is in the best interests of shareholders to do so. During these
periods, the Fund may not achieve its objective of capital appreciation.

Important Risk Factors
Foreign company stocks may lose value or be more difficult to trade as a result
of adverse changes in currency exchange rates or other developments in the
issuer's home country. Concentrated investment in any single country, especially
a less developed country, would make the Fund's value more sensitive to
economic, currency and regulatory changes within that country. Emerging market
countries are often dependent on international trade and are therefore often
vulnerable to events in other countries. They may have less developed financial
systems and volatile currencies and may be more sensitive than more mature
markets to a variety of economic factors. Emerging market securities may also be
less liquid than securities of more developed countries, which may make them
more difficult to sell, particularly during a market downturn.

International Fund

Investment Objective
The International Fund's investment objective is to provide long-term capital
appreciation by investing directly or indirectly in high-quality companies based
outside the United States.

Investment Policies
The Fund invests in a "multi-style" approach designed to minimize the volatility
and risk of investing in international securities.

Permitted Investments
The Fund's investment portfolio combines 2 different investment styles -- an
international equity investment style and an international emerging markets
investment style. The Fund invests in 2 Portfolios.

Important Risk Factors
Foreign company stocks may lose value or be more difficult to trade as a result
of adverse changes in currency exchange rates or other developments in the
issuer's home country. Concentrated investment in any single country, especially
a less developed country, would make the Fund's value more sensitive to
economic, currency and regulatory changes within that country. Emerging market
countries are often dependent on international trade and are therefore often
vulnerable to events in other countries. They may have less developed financial
systems and volatile currencies and may be more sensitive than more mature
markets to a variety of economic factors. Emerging market securities may also be
less liquid than securities of more developed countries, which may make them
more difficult to sell, particularly during a market downturn.

Large Company Growth Fund

Investment Objective
The Large Company Growth Fund's investment objective is to provide long-term
capital appreciation by investing primarily in large, high-quality domestic
companies that the Advisor believes have superior growth potential.

Investment Policies
The Fund invests primarily in the common stock of large, high-quality domestic
companies that have superior growth potential.

Permitted Investments
The Advisor considers large companies to be those whose Market Capitalization is
greater than the median of the Russell 1000 Index or approximately $3.7 billion.
In selecting securities for the Fund, the Advisor seeks issuers whose stock is
attractively valued with fundamental characteristics that are significantly
better than the market average and support internal earnings growth capability.
The Fund may invest in the securities of companies whose growth potential is, in
the Advisor's opinion, generally unrecognized or misperceived by the market.
The Fund may not invest more than 10% of its total assets in the securities of a
single issuer.

Important Risk Factors
The Fund may invest up to 20% of its total assets in the securities of foreign
companies and may hedge against currency risk by using foreign currency forward
contracts. Foreign company stocks may lose value or be more difficult to trade
as a result of adverse changes in currency exchange rates or other developments
in the issuer's home country. Concentrated investment in any single country,
especially a less developed country, would make the Fund's value more sensitive
to economic, currency and regulatory changes within that country. Emerging
market countries are often dependent on international trade and are therefore
often vulnerable to events in other countries. They may have less developed
financial systems and volatile currencies and may be more sensitive than more
mature markets to a variety of economic factors. Emerging market securities may
also be less liquid than securities of more developed countries, which may make
them more difficult to sell, particularly during a market downturn.

Small Cap Opportunities Fund

Investment Objective
The Small Cap Fund's investment objective is to provide capital appreciation.

Investment Policies
The Fund invests primarily in equity securities of U.S. companies that, at the
time of purchase, have market capitalizations of $1.5 billion or less.

The Advisor attempts to identify securities of companies that it believes can
generate above-average earnings growth and sell at favorable prices in relation
to book values and earnings. The Advisor's assessment of a company's
management's competence will be an important consideration. These criteria are
not rigid and the Fund may make other investments to achieve its objective.

Permitted Investments
The Fund will invest principally in equity securities, including common stocks,
securities convertible into common stocks or, subject to special limitations,
rights or warrants to subscribe for or purchase common stocks. The Fund also may
invest to a limited degree in non-convertible debt securities and preferred
stocks.

The Fund may use options and futures contracts to manage risk.  The Fund also
may use options to enhance return.

Important Risk Factors
This Fund is designed for investors willing to assume above-average risk. We may
invest in companies that:

 .  pay low or no dividends;
 .  have smaller market capitalization;
 .  have less market liquidity;
 .  have no or relatively short operating histories, or are new public companies
   or are initial public offerings;
 .  have aggressive capital structures including high debt levels; or
 .  are involved in rapidly growing or changing industries and/or new
   technologies.

Because we may invest in such aggressive securities, share prices may rise and
fall more than the share prices of other funds. In addition, our active trading
investment strategy may result in a higher-than-average portfolio turnover
ratio, increased trading expenses, and higher short-term capital gains.

Small Cap Value Fund

Investment Objective
The Small Cap Value Fund's investment objective is to seek capital appreciation
by investing primarily in common stocks of smaller companies.

Investment Policies
The Fund seeks capital appreciation by investing in common stocks of smaller
companies. The Fund will normally invest substantially all of its assets in
securities of companies with market capitalizations that reflect the market
capitalization of companies included in the Russell 2000 Index, which range from
approximately $220 million to approximately $1.4 billion.

Permitted Investments
The Fund seeks higher growth rates and greater long-term returns by investing
primarily in the common stock of smaller companies that the Advisor believes to
be undervalued and likely to report a level of corporate earnings exceeding the
level expected by investors. The Advisor values companies based upon both the
price-to-earnings ratio of the company and a comparison of the public market
value of the company to a proprietary model that values the company in the
private market. In seeking companies that will report a level of earnings
exceeding that expected by investors, the Advisor uses both quantitative and
fundamental analysis. Among other factors, the Advisor considers changes of
earnings estimates by investment analysts, the recent trend of company earnings
reports, and the fundamental business outlook for the company.

Important Risk Factors
This Fund is designed for investors willing to assume above-average risk.  We
may invest in companies that:
 .  pay low or no dividends;
 .  have smaller market capitalization;
 .  have less market liquidity;
 .  have no or relatively short operating histories, or are new public companies
   or are initial public offerings;
 .  have aggressive capital structures including high debt levels; or
 .  are involved in rapidly growing or changing industries and/or new
   technologies.
Because we may invest in such aggressive securities, share prices may rise and
fall more than the share prices of other funds. In addition, our active trading
investment strategy may result in a higher-than-average portfolio turnover
ratio, increased trading expenses, and higher short-term capital gains.

Small Company Growth Fund

Investment Objective
The Small Company Growth Fund's investment objective is to provide long-term
capital appreciation by investing in smaller domestic companies.

Investment Policies
The Fund invests primarily in the common stock of small and medium-sized
domestic companies that are either growing rapidly or completing a period of
significant change. Small companies are those companies whose market
capitalization is less than the largest stock in the Russell 2000 Index or
approximately $1.4 billion.

Permitted Investments
In selecting securities for the Fund, the Adviser seeks to identify companies
that are rapidly growing (usually with relatively short operating histories) or
that are emerging from a period of investor neglect by undergoing a dramatic
change. These changes may involve a sharp increase in earnings, the hiring of
new management or measures taken to close the gap between share price and
takeover/asset value.

The Fund will invest up to 10% of its total assets in securities of foreign
companies. The Fund will not invest more than 10% of its total assets in the
securities of a single issuer.

Important Risk Factors
This Fund is designed for investors willing to assume above-average risk. We
may invest in companies that:
 . pay low or no dividends;
 . have smaller market capitalization;
 . have less market liquidity;
 . have no or relatively short operating histories, or are new public companies
  or are initial public offerings;
 . have aggressive capital structures including high debt levels; or
 . are involved in rapidly growing or changing industries and/or new
  technologies.
Because we may invest in such aggressive securities, share prices may rise and
fall more than the share prices of other funds. In addition, our active trading
investment strategy may result in a higher-than-average portfolio turnover

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds. Certain common risks are identified in the
Summary of Important Risks on page ___. Other risks of mutual fund investing
include the following:

 .  Unlike bank deposits, such as CDs or savings accounts, mutual funds are not
   insured by the FDIC.
 .  We cannot guarantee that we will meet our investment objectives.
 .  We do not guarantee the performance of a Fund, nor can we assure you that the
   market value of your investment will not decline. We will not "make good" any
   investment loss you may suffer, nor can anyone we contract with to provide
   certain services, such as selling agents or investment advisors, offer or
   promise to make good any such losses.
 .  Share prices -- and therefore the value of your investment -- will increase
   and decrease with changes in the value of the underlying securities and other
   investments.
 .  Investing in any mutual fund, including those deemed conservative, involves
   risk, including the possible loss of any money you invest.
 .  An investment in a single Fund, by itself, does not constitute a complete
   investment plan.
 .  The Funds that invest in smaller companies, foreign companies (including
   investments made through American Depositary Receipts and similar
   instruments), and in emerging markets are subject to additional risks,
   including less liquidity and greater price volatility. A Fund's investment in
   foreign and emerging markets may also be subject to special risks associated
   with international trade, including currency, political, regulatory and
   diplomatic risk.
 .  The Funds may invest a portion of their assets in U.S. Government
   obligations. It is important to recognize that the U.S. Government does not
   guarantee the market value or current yield of those obligations. Not all
   U.S. Government obligations are backed by the full faith and credit of the
   U.S. Treasury, and the U.S. Government's guarantee does not extend to the
   Funds themselves.
 .  The Funds may also use certain derivative instruments, such as options or
   futures contracts. The term "derivatives" covers a wide number of
   investments, but in general it refers to any financial instrument whose value
   is derived, at least in part, from the price of another security or a
   specified index, asset or rate. Some derivatives may be more sensitive to
   interest rate changes or market moves, and some may be susceptible to changes
   in yields or values due to their structure or contract terms.
 .  The Funds may temporarily hold assets in cash or in money market instruments,
   including U.S. Government obligations, shares of other mutual funds and
   repurchase agreements, or make other short-term investments, either to
   maintain liquidity or for short-term defensive purposes when we believe it is
   in the best interests of shareholders to do so. Except with respect to money
   market funds, to the extent a Fund's assets are so invested, they may use a
   Fund to not achieve its investment objective. This practice is expected to
   have limited, if any, effect on the Funds' pursuit of their objectives over
   the long term.
 .  The Funds may invest a portion of their assets in U.S. Government
   obligations, such as securities issued or guaranteed by the Government
   National Mortgage Association (GNMAs"), the Federal National Mortgage
   Association ("FNMAs") and the Federal Home Loan Mortgage Corporation
   ("FHLMCs"). Each are mortgage-backed securities representing partial
   ownership of a pool of residential mortgage loans. A "pool" or group of such
   mortgages is assembled and, after being approved by the issuing or
   guaranteeing entity, is offered to investors through securities risk, which
   can alter the maturity of the securities and also reduce the rate of return
   on the portfolio. Collateralized mortgage obligations ("CMOs") typically
   represent principal-only and interest-only portions of such securities and
   are subject to increased interest-rate and credit risk.
 .  The market value of lower-rated debt securities and unrated securities of
comparable quality that the Funds may invest in tends to reflect individual
developments affecting the issuer to a greater extend than the market value of
higher-rated securities, which react primarily to fluctuations in the general
level of interest rates. Lower-rated securities also tend to be more sensitive
to economic conditions than higher-rated securities. These lower-rated debt
securities are considered by the rating agencies, on balance, to be
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal. These

                                       27
<PAGE>

   securities generally involve more credit risk than securities in higher-
   rating categories. Even securities rated "BBB" by S&P or by Moody's rating
   which are considered investment-grade, possess some speculative
   characteristics.

   Investment practices and risk levels are carefully monitored. Every attempt
   is made to ensure that the risk exposure for each Fund remains within the
   parameters of its objective.

   What follows is a general list of the types of risks (some of which are
   described above) that may apply to a given Fund and a table showing some of
   the additional investment practices that each Fund may use and the risks
   associated with them. Additional information about these practices is
   available in the Statement of Additional Information.

   Counter-Party Risk -- The risk that the other party in a repurchase agreement
   or other transaction will not fulfill its contract obligation.

   Credit Risk -- The risk that the issuer of a debt security will be unable to
   make interest payments or repay principal on schedule. If an issuer does
   default, the affected security could lose all of its value, or be
   renegotiated at a lower interest rate or principal amount. Affected
   securities might also lose liquidity. Credit risk also includes the risk that
   a party in a transaction may not be able to complete the transaction as
   agreed.

   Currency Risk-- The risk that a change in the exchange rate between U.S.
   dollars and a foreign currency may reduce the value of an investment made in
   a security denominated in that foreign currency.

   Diplomatic Risk--The risk that an adverse change in the diplomatic relations
   between the United States and another country might reduce the value of
   liquidity of investments in either country.

   Emerging Market Risk--The risk that the emerging market, as defined in the
   glossary, may be more sensitive to certain economic changes. For example,
   emerging market countries are often dependent on international trade and are
   therefore often vulnerable to recessions in other countries. They may have
   obsolete financial systems, have volatile currencies and may be more
   sensitive than more mature markets to a variety of economic factors. Emerging
   market securities may also be less liquid than securities of more developed
   countries and could be difficult to sell, particularly during a market
   downturn.

   Experience Risk--The risk presented by a new or innovative security. The risk
   is that insufficient experience exists to forecast how the security's value
   might be affected by various economic conditions.

   Information Risk--The risk that information about a security is either
   unavailable, incomplete or is inaccurate.

   Interest Rate Risk--The risk that changes in interest rates can reduce the
   value of an existing security. Generally, when interest rates increase, the
   value of a debt security decreases. The effect is usually more pronounced for
   securities with longer dates to maturity.

   Leverage Risk--The risk that an investment practice, such as lending
   portfolio securities or engaging in forward commitment or when issued
   securities transactions, may increase a Fund's exposure to market risk,
   interest rate risk or other risks by, in effect, increasing assets available
   for investment.

   Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
   without adversely affecting the price.

   Market Risk--The risk that the value of a stock, bond or other security will
   be reduced by market activity. This is a basic risk associated with all
   securities.

   Political Risk--The risk that political actions, events or instability may be
   unfavorable for investments made in a particular nation's or region's
   industry, government or markets.

                                       28
<PAGE>

   Prepaying Risk--The risk that consumers will accelerate their prepayment of
   mortgage loans or other receivable, which can shorten the maturity of a
   mortgage-backed or other asset-backed security, and reduce a portfolio's
   return.

   Regulatory Risk--The risk that changes in government regulations will
   adversely affect the value of a security. Also the risk that an
   insufficiently regulated market might permit inappropriate trading practices.

   Year 2000 Risk--The Funds' principal service providers have advised the Funds
   that they are working on the necessary changes to their computer systems to
   avoid any system failure based on an inability to distinguish the year 2000
   from the year 1900, and that they expect their systems to be adapted in time.
   There can, of course, be no assurance of success. In addition, the companies
   or entities in which the Funds invest also could be adversely impacted by the
   Year 2000 issue, especially foreign entities, which may be less prepared for
   Year 2000. The extent of such impact cannot be predicted.

   In addition to the general risks discussed above, you should carefully
   consider and evaluate any special risks that may apply to investing in a
   particular Fund. See the "Important Risk Factors" in the summary for each
   Fund. You should also see the Statement of Additional Information for
   additional information about the investment practices and risks particular to
   each Fund.

Organization and Management of the Funds

A number of different entities provide services to the Funds.  This section
shows how the Funds are organized, lists the entities that perform different
services, and explains how these service providers are compensated.  Further
information is available in the Statement of Additional Information for the
Funds.

About Wells Fargo Funds Trust
Wells Fargo Funds Trust (the "Trust") was organized as a Delaware business trust
on March 10, 1999.  The Board of Trustees of the Trust supervises each Fund's
activities, monitors its contractual arrangements with various service providers
and decides upon matters of general policy.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds.  The holding company of Wells Fargo Bank, the investment advisor to
the Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998.  Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one or more Stagecoach
and/or Norwest Advantage Funds.  One of these predecessor funds is expected to
be the "accounting survivor," which means that its performance and financial
statement history will be assumed by the Wells Fargo Funds Trust Fund.  The
succession transactions are conditioned on shareholder approval by the
shareholders of the various Stagecoach and Norwest Advantage Funds.  The Table
on page __ identifies the expected accounting survivors.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund class paid on an annual basis for the
services described.

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:
 .    As with all mutual fund investments, the price you pay to purchase shares
     or the price you receive when you redeem shares is not determined until
     after a request has been received in proper form.

 .    We determine the Net Asset Value ("NAV") of each class of the Funds' shares
     each business day as of the close of regular trading on the NYSE. We
     determine the NAV by subtracting the Fund class's liabilities from its
     total assets, and then dividing the result by the total number of
     outstanding shares of that class. Each Fund's assets are generally valued
     at current market prices. See the Statement of Additional Information for
     further disclosure.

 .    We process requests to buy or sell shares of the non-money market funds
     each business day as of the close of regular trading on the New York Stock
     Exchange ("NYSE"), which is usually 1:00 p.m. (Pacific time)/3:00 p.m.
     (Central time). If the markets close early, the Funds may close early and
     may value their shares at earlier times under these circumstances. Any
     request we receive in proper form before the close of regular trading on
     the NYSE is processed the same day. Requests we receive after the cut off
     are processed the next business day.

 .    The Funds are open for business on each day the NYSE is open for business.
     NYSE holidays include New Year's Day, Martin Luther King, Jr. Day,
     President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
     Thanksgiving Day and Christmas Day. When any holiday falls on a weekend,
     the NYSE typically is closed on the weekday immediately before or after
     such holiday.

Typically, Institutional Class shares are bought and held on your behalf by the
Institution through which you are investing.  Check with your customer account
representative or your Customer Account Agreement for the rules governing your
investment.

Minimum Investments:
 .    Minimum initial investment amounts are determined by your Customer Account
     Agreement with your Institution, and are generally:

     .    $2,000,000 per Fund minimum initial investment.

How to Buy Shares
You can open a Fund account and buy Fund shares through an Institution through
which you have established a Customer Account.  Investors interested in
purchasing Institutional shares of the Funds should contact an account
representative at their Institution and should understand the following:

 .    Share purchases are made through a Customer Account at an Institution in
     accordance with the terms of the Customer Account involved;

 .    Institutions are usually the holders of record of Institutional shares held
     through Customer Accounts and maintain records reflecting their customers'
     beneficial ownership of the shares;

 .    Institutions are responsible for transmitting their customers' purchase and
     redemption orders to the Funds and for delivering required payment on a
     timely basis;

 .    The exercise of voting rights and the delivery of shareholder
     communications from the Funds is governed by the terms of the Customer
     Account involved; and

 .    Institutions may charge their customers account fees and may receive fees
     from us with respect to investments their customers have made with the
     Funds. See "Organization and Management of the Funds" for further details
     about these fees.

Your Account (Cont'd)

How to Sell Shares
Institutional shares must be redeemed in accordance with the account agreement
governing your Customer Account at the Institution.  Please read the Customer
Account agreement with your Institution for rules governing selling shares.

General notes for selling shares
 .    We process requests we receive from an Institution in proper form before
     the close of the NYSE, usually 1:00 P.M. Pacific time, at the NAV
     determined on the same business day. Requests we receive after this time
     are processed on the next business day.

 .    Redemption proceeds are usually wired to the redeeming Institution the
     following business day.

 .    We reserve the right to delay payment of a redemption for up to 15 days so
     that we may be reasonably certain that investments made by check have been
     collected. Payments of redemptions also may be delayed under extraordinary
     circumstances or as permitted by the SEC in order to protect remaining
     shareholders. Payments of redemptions also may be delayed up to seven days
     under normal circumstances, although it is not our policy to delay such
     payments.

 .    Generally, we pay redemption requests in cash, unless the redemption
     requests is for more than $250,000 or 1% of the net assets of the Fund by a
     single shareholder over a ninety-day period. If a request for a redemption
     is over these limits it may be to the detriment of existing shareholders.
     Therefore, we may pay the redemption in part on in whole in securities of
     equal value.

Exchanges
Exchanges between Wells Fargo Funds are two transactions:  a sale of one Fund
and the purchase of another.  In general, the same rules and procedures that
apply to sales and purchases apply to exchanges.  There are, however, additional
factors you should keep in mind while making or considering an exchange:

 .    You should carefully read the Prospectus for the Fund into which you wish
     to exchange.

 .    Every exchange involves selling Fund shares and that sale may produce a
     capital gain or loss for federal income tax purposes.

 .    If you are making an initial investment into a new Fund through an
     exchange, you must exchange at least the minimum first purchase amount of
     the Fund you are redeeming, unless your balance has fallen below that
     amount due to market conditions.

 .    Any exchange between Funds you already own must meet the minimum redemption
     and subsequent purchase amounts for the Funds involved.

 .    In order to discourage excessive Fund transaction expenses that must be
     borne by other shareholders, we reserve the right to limit or reject
     exchange orders. Generally, we will notify you 60 days in advance of any
     changes in your exchange privileges.

 .    You may make exchanges only between like share classes.

Additional Services and Other Information

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus.  The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder.  It
is not intended as a substitute for careful tax planning.  You should consult
your tax advisor about your specific tax situation.  Federal income tax
considerations are discussed further in the Statement of Additional Information.

Dividends distributed from the Funds attributable to their income from other
investments and net short-term capital gain (generally, the excess of net short-
term capital gains over net long-term capital losses) will be taxable to you as
ordinary income.  Corporate shareholders may be able to deduct a portion of
their dividends when determining their taxable income.

We will pass on to you any net capital gain (generally the excess of net long-
term capital gains over net short-term capital losses) earned by a Fund as a
capital gain distribution.  In general, these distributions will be taxable to
you as long-term capital gains which may qualify for taxation at preferential
rates in the hands of non-corporate shareholders.  Any distribution that is not
from net investment income, short term capital gains, or net capital gain may be
characterized as a return of capital to shareholders.

                             TABLE OF PREDECESSORS

                            INVESTMENT RESTRICTIONS

     Fundamental Investment Policies
     -------------------------------

     Each Fund has adopted the following investment restrictions, all of which
are fundamental policies; that is, they may not be changed, without approval by
the holders of a majority (as defined in the Investment Company Act of 1940, as
amended (the "1940 Act")) of the outstanding voting securities of such Fund.

The Funds may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of a Fund's investments in that industry would equal 25% of
the current value of the Fund's total assets, provided that there is no
limitation with respect to investment in securities issued or guaranteed by the
United States Government, its agencies or instrumentalities;

                                       2
<PAGE>

     (2)  purchase securities of any issuer if, as a result, with respect to 75%
of a Fund's total assets, more than 5% of the value of its total assets would be
invested in the securities of any one issuer or, with respect to 100% of its
assets, the Fund's ownership would be more than 10% of the outstanding voting
securities of such issuer.  This policy does not restrict a Fund's ability to
invest in securities issued or guaranteed by the U.S. Government, its agencies
and instrumentalities; or to invest substantially all of its assets in  the
portfolio of one or more open-end management investment companies pursuant to
Section 12 of the 1940 Act and the rules thereunder;

     (3)  borrow money except to the extent permitted by the 1940 Act, and the
rules, regulations and exemptions thereunder;

     (4)  issue senior securities  except to the extent permitted by the 1940
Act, and the rules, regulations and exemptions thereunder;

     (5)  make loans to other parties if, as a result, the aggregate value of
such loans would exceed one-third of a Fund's total assets.  For the purposes of
this limitation, entering into repurchase agreements, lending securities and
acquiring any debt securities are not deemed to be the making of loans;

     (6)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer and the later disposition of such securities in
accordance with a Fund's investment program may be deemed to be an underwriting;

     (7)  purchase or sell real estate unless acquired as a result of ownership
of securities or other instruments (but this shall not prevent the Fund from
investing in securities or other instruments backed by real estate or securities
of companies engaged in the real estate business); nor

     (8)  purchase or sell physical commodities unless acquired as a result of
ownership of securities or other instruments (but this shall not prevent the
Funds from purchasing or selling options and futures contracts, or from
investing in securities or other instruments backed by physical commodities.

     Non-Fundamental Investment Policies
     -----------------------------------

     Each Fund has adopted the following non-fundamental policies which may be
changed by a vote of a majority of the Trustees of the Trust or at any time
without approval of such Fund's shareholders.

     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of the 1940 Act, the rules thereunder, and
any orders obtained thereunder now or in the future. Funds in a master/feeder or
core/gateway structure, such as the Income Equity Fund, generally invest in the
securities of one or more open-end

                                       3
<PAGE>

management investment companies pursuant to various provisions of the 1940 Act.
Other investment companies in which the Funds invest can be expected to charge
fees for operating expenses, such as investment advisory and administration
fees, that would be in addition to those charged by a Fund.

     (2)  Each Fund may not invest or hold more than 15% of the Fund's net
assets in illiquid securities. For this purpose, illiquid securities include,
among others, (a) securities that are illiquid by virtue of the absence of a
readily available market or legal or contractual restrictions on resale, (b)
fixed time deposits that are subject to withdrawal penalties and that have
maturities of more than seven days, and (c) repurchase agreements not terminable
within seven days.

     (3)  Each Fund may invest in futures or options contracts regulated by the
CFTC for (i) bona fide hedging purposes within the meaning of the rules of the
CFTC and (ii) for other purposes if, as a result, no more than 5% of the Fund's
net assets would be invested in initial margin and premiums (excluding amounts
"in-the-money") required to establish the contracts.

          Each Fund (i) will  not hedge more than [50%] of its total assets by
selling futures contracts, buying put options, and writing call options (so
called "short positions"),  (ii) will not buy futures contracts or write put
options whose underlying value exceeds [25%] of the Fund's total assets, and
(iii) will not buy call options with a value exceeding [5%] of the Fund's total
assets.

     (4)  Each Fund may lend securities from its portfolio to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) up to
the limits established by and under the 1940 Act, including any exemptive relief
obtained thereunder, which limits are currently generally one-third of a Fund's
total assets. Any such loans of portfolio securities will be fully
collateralized based on values that are marked to market daily. [A Fund will not
enter into any portfolio security lending arrangement having a duration of
longer than one year.]

     (5)  Each Fund may not make investments for the purpose of exercising
control or management. (Investments by the Fund in entities created under the
laws of foreign countries solely to facilitate investment in securities in that
country will not be deemed the making of investments for the purpose of
exercising control.)

     (6)  Each Fund may not purchase securities on margin (except for short-term
credits necessary for the clearance of transactions).

     (7)  Each Fund may not sell securities short, unless it owns or has the
right to obtain securities equivalent in kind and amount to the securities sold
short (short sales "against the box"), and provided that transactions in futures
contracts and options are not deemed to constitute selling securities short.

     (8)  Each Fund may not purchase interests, leases, or limited partnership
interests in oil, gas, or other mineral exploration or development programs.

        ADDITIONAL PERMITTED INVESTMENT ACTIVITIES AND ASSOCIATED RISKS

     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

     Bank Obligations
     ----------------

     The Funds, except the International Equity Fund, may invest in bank
obligations, including certificates of deposit, time deposits, bankers'
acceptances and other short-term obligations of domestic banks, foreign
subsidiaries of domestic banks, foreign branches of domestic banks, and domestic
and foreign branches of foreign banks, domestic savings and loan associations
and other banking institutions.  With respect to such securities issued by
foreign branches of domestic banks, foreign subsidiaries of domestic banks, and
domestic and foreign branches of foreign banks, a Fund may be subject to
additional investment risks that are different in some respects from those
incurred by a Fund which invests only in debt obligations of U.S. domestic
issuers.  Such risks include possible future political and economic
developments, the possible imposition of foreign withholding taxes on interest
income payable on the securities, the possible establishment of exchange
controls or the adoption of other foreign governmental restrictions which might
adversely affect the payment of principal and interest on these securities and
the possible seizure or nationalization of foreign deposits.  In addition,
foreign branches of U.S. banks and foreign banks may be subject to less
stringent reserve requirements and to different accounting, auditing, reporting
and recordkeeping standards than those applicable to domestic branches of U.S.
banks.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate.  Time
deposits which may be held by a Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation ("FDIC").  Bankers' acceptances are
credit instruments evidencing the obligation of a bank to pay a draft drawn on
it by a customer.  These instruments reflect the obligation both of the bank and
of the drawer to pay the face amount of the instrument upon maturity.  The other
short-term obligations may include uninsured, direct obligations, bearing fixed,
floating- or variable-interest rates.

     Commercial Paper
     ----------------

     The Funds, except the International Equity Fund, may invest in commercial
paper (including variable amount master demand notes) which refers to short-
term, unsecured promissory notes issued by corporations to finance short-term
credit needs.  Commercial paper is usually sold on a discount basis and has a
maturity at the time of issuance not exceeding nine months.  Variable amount
master demand notes are demand obligations which permit the investment of
fluctuating amounts at varying market rates of interest pursuant to arrangements
between the issuer and a commercial bank acting as agent for the payee of such
notes whereby both parties have the right to vary the amount of the outstanding
indebtedness on the notes.  Investments by the Funds in

                                       5
<PAGE>

commercial paper (including variable rate demand notes and variable rate master
demand notes issued by domestic and foreign bank holding companies, corporations
and financial institutions, as well as similar instruments issued by government
agencies and instrumentalities) will consist of issues that are rated in one of
the two highest rating categories by a Nationally Recognized Ratings
Organization ("NRRO"). Commercial paper may include variable- and floating-rate
instruments.

     Convertible Securities
     ----------------------

     The Diversified Equity, Growth Equity, Equity Index and Equity Value Funds
may invest in convertible securities that provide current income and are issued
by companies with the characteristics described above for each Fund and that
have a strong earnings and credit record.  The Funds may purchase convertible
securities that are fixed-income debt securities or preferred stocks, and which
may be converted at a stated price within a specified period of time into a
certain quantity of the common stock of the same issuer.  Convertible
securities, while usually subordinate to similar nonconvertible securities, are
senior to common stocks in an issuer's capital structure.  Convertible
securities offer flexibility by providing the investor with a steady income
stream (which generally yield a lower amount than similar nonconvertible
securities and a higher amount than common stocks) as well as the opportunity to
take advantage of increases in the price of the issuer's common stock through
the conversion feature.  Fluctuations in the convertible security's price can
reflect changes in the market value of the common stock or changes in market
interest rates.  At most, 5% of each Fund's net assets will be invested, at the
time of purchase, in convertible securities that are not rated in the four
highest rating categories by one or more NRROs, such as Moodys Investors
Service, Inc. ("Moodys") or Standard & Poor's Ratings Group ("S&P"), or unrated
but determined by the Advisor to be of comparable quality.

     Custodial Receipts for Treasury Securities
     ------------------------------------------

     The Funds, except the International Equity Fund, may purchase
participations in trusts that hold U.S. Treasury securities (such as TIGRs and
CATS) or other obligations where the trust participations evidence ownership in
either the future interest payments or the future principal payments on the
obligations.  These participations are normally issued at a discount to their
"face value," and can exhibit greater price volatility than ordinary debt
securities because of the way in which their principal and interest are returned
to investors.  Investments by a Fund in such participations will not exceed 5%
of the value of that Fund's total assets.

     Derivative Securities: Futures and Options Contracts
     ----------------------------------------------------

     Futures and options contracts are types of "derivative securities" in which
the Diversified Equity Small Cap Growth and International Equity Funds may
invest.  Derivative securities are securities which derive their value, at least
in part, from the price of another security or asset, or the level of an index
or a rate.  As is described in more detail below, a Fund often invests in these
securities as a "hedge" against fluctuations in the value of the other
securities in that Fund's portfolio, although a Fund may also invest in certain
derivative securities for investment purposes only.

                                       6
<PAGE>

     While derivative securities are useful for hedging and investment, they
also carry additional risks.  A hedging policy may fail if the correlation
between the value of the derivative securities and the other investments in a
Fund's portfolio does not follow the Advisor's expectations.  If the Advisor's
expectations are not met, it is possible that the hedging strategy will not only
fail to protect the value of the Fund's investments, but the Fund may also lose
money on the derivative security itself.  Also, derivative securities are more
likely to experience periods when they will not be readily tradable.  If, as a
result of such illiquidity, a Fund cannot settle a future or option contract at
the time the Advisor determines is optimal, the Fund may lose money on the
investment.  Additional risks of derivative securities include: the risk of the
disruption of the Funds' ability to trade in derivative securities because of
regulatory compliance problems or regulatory changes; credit risk of
counterparties to derivative contracts; and market risk (i.e., exposure to
adverse price changes).

     Each Fund has the following non-fundamental investment policies with regard
to investing in derivative securities:

     .    Each Fund may invest in futures or options contracts regulated by the
          Commodities Futures Trading Commission ("CFTC") for (i) bona fide
          hedging purposes within the meaning of the rules of the CFTC and (ii)
          for other purposes if, as a result, no more than 5% of the Fund's net
          assets would be invested in initial margin and premiums (excluding
          amounts "in-the-money") required to establish the contracts.

     .    Each Fund (i) will not hedge more than [50%] of its total assets by
          selling futures contracts, buying put options, and writing call
          options (so called "short positions"), (ii) will not buy futures
          contracts or write put options whose underlying value exceeds [25%] of
          the Fund's total assets, and (iii) will not buy call options with a
          value exceeding [5%] of the Fund's total assets.

     The Advisor uses a variety of internal risk management procedures to ensure
that derivatives use is consistent with a Fund's investment objectives, does not
expose a Fund to undue risk and is closely monitored.  These procedures include
providing periodic reports to the Board of Trustees concerning the use of
derivatives.

     The use of derivatives by a Fund also is subject to broadly applicable
investment policies.  For example, a Fund may not invest more than a specified
percentage of its assets in "illiquid securities," including those derivatives
that do not have active secondary markets.  Nor may a Fund use certain
derivatives without establishing adequate "cover" in compliance with the U.S.
Securities and Exchange Commission ("SEC") rules limiting the use of leverage.

                                       7
<PAGE>

     Futures Contracts.  The Funds may trade futures contracts and options on
futures contracts.  A futures transaction involves a firm agreement to buy or
sell a commodity or financial instrument at a particular price on a specified
future date.  Futures contracts are standardized and exchange-traded, where the
exchange serves as the ultimate counterparty for all contracts.  Consequently,
the only credit risk on futures contracts is the creditworthiness of the
exchange.

     The purchaser or seller of a futures contract is not required to deliver or
pay for the underlying instrument unless the contract is held until the delivery
date.  However, both the purchaser and seller are required to deposit "initial
margin" with a futures broker when the parties enter into the contract.  Initial
margin deposits are typically equal to a percentage of the contract's value.  If
the value of either party's position declines, that party will be required to
make additional "variation margin" payments to settle the change in value on a
daily basis.  The party that has a gain may be entitled to receive all or a
portion of this amount.  Initial and variation margin payments do not constitute
purchasing securities on margin for purposes of a Fund's investment limitations.
In the event of the bankruptcy of the broker that holds the margin on behalf of
a Fund, the Fund may not receive a full refund of its margin.

     Although the Funds intend to purchase or sell futures contracts only if
there is an active market for such contracts, a liquid market may not exist for
a particular contract at a particular time.  Many futures exchanges and boards
of trade limit the amount of fluctuation permitted in futures contract prices
during a single trading day.  Once the daily limit has been reached in a
particular contract, no trades may be made that day at a price beyond that limit
or trading may be suspended for specified periods during the trading day.
Futures contracts prices could move to the limit for several consecutive trading
days with little or no trading, thereby preventing prompt liquidation of futures
positions and potentially subject a Fund to substantial losses.  If it is not
possible, or a Fund determines not to close a futures position in anticipation
of adverse price movements, the Fund may be required to pay additional variation
margin until the position is closed.

     The Funds may also purchase options on futures contracts.  See "Options
Trading" below.

     Foreign Currency Futures Contracts and Foreign Currency Transactions.  The
Diversified Small Cap, Growth Equity, Large Company Growth, Small Company
Growth, Equity Index, Equity Value and International Equity Funds can invest in
foreign currency futures contracts and foreign currency transactions which
entail the same risks as other futures contracts as described above, but have
the additional risks associated with international investing (see "Foreign
Obligations and Securities" below).  Similar to other futures contracts, a
foreign currency futures contract is an agreement for the future delivery of a
specified currency at a specified time and at a specified price, will be secured
by margin deposits, are regulated by the CFTC and are traded on designated
exchanges.  A Fund will incur brokerage fees when it purchases and sells futures
contracts.

     Foreign currency transactions, such as forward foreign currency exchange
contracts, are also contracts for the future delivery of a specified currency at
a specified time and at a specified price.  These transactions differ from
futures contracts in that they are usually conducted on a

                                       8
<PAGE>

principal basis instead of through an exchange, and therefore there are no
brokerage fees, margin deposits are negotiated between the parties, and the
contracts are settled through different procedures. The Advisor, considers on an
ongoing basis the creditworthiness of the institutions with which the Fund
enters into foreign currency transactions. Despite these differences, however,
foreign currency futures contracts and foreign currency transactions (together,
"Currency Futures") entail largely the same risks, and therefore the remainder
of this section will describe the two types of securities together.

     Because the Funds may invest in securities denominated in currencies other
than the U.S. dollar and may temporarily hold funds in bank deposits or other
money market investments denominated in foreign currencies, they may be affected
favorably or unfavorably by exchange control regulations or changes in the
exchange rate between such currencies and the dollar.  Changes in foreign
currency exchange rates influence values within the Fund from the perspective of
U.S. investors.  The rate of exchange between the U.S. dollar and other
currencies is determined by the forces of supply and demand in the foreign
exchange markets.  The international balance of payments and other economic and
financial conditions, government intervention, speculation and other factors
affect these forces.

     A Fund will purchase and sell Currency Futures in order to hedge its
portfolio and to protect it against possible variations in foreign exchange
rates pending the settlement of securities transactions.  If a fall in exchange
rates for a particular currency is anticipated, a Fund may sell a Currency
Future as a hedge.  If it is anticipated that exchange rates will rise, a Fund
may purchase a Currency Future to protect against an increase in the price of
securities denominated in a particular currency the Fund intends to purchase.
These Currency Futures will be used only as a hedge against anticipated currency
rate changes.  Although such contracts are intended to minimize the risk of loss
due to a decline in the value of the hedged currency, at the same time, they
tend to limit any potential gain which might result should the value of such
currency increase.

     The use of Currency Futures involves the risk of imperfect correlation
between movements in futures prices and movements in the price of currencies
which are the subject of the hedge.  The successful use of Currency Futures
strategies also depends on the ability of the Advisor to correctly forecast
interest rate movements, currency rate movements and general stock market price
movements.  There can be no assurance that the Advisor's judgment will be
accurate.  The use of Currency Futures also exposes a Fund to the general risks
of investing in futures contracts: the risk of an illiquid market for the
Currency Futures, the risk of exchange-imposed trading limits, and the risk of
adverse regulatory actions.  Any of these events may cause a Fund to be unable
to hedge its securities, and may cause a Fund to lose money on its Currency
Futures investments.

     The Funds may also purchase options on Currency Futures.  See "Options
Trading" below.

                                       9
<PAGE>

     Options Trading.  The Funds may purchase or sell options on individual
securities or options on indices of securities.  The purchaser of an option
risks a total loss of the premium paid for the option if the price of the
underlying security does not increase or decrease sufficiently to justify the
exercise of such option.  The seller of an option, on the other hand, will
recognize the premium as income if the option expires unrecognized but foregoes
any capital appreciation in excess of the exercise price in the case of a call
option and may be required to pay a price in excess of current market value in
the case of a put option.

     A call option for a particular security gives the purchaser of the option
the right to buy, and a writer the obligation to sell, the underlying security
at the stated exercise price at any time prior to the expiration of the option,
regardless of the market price of the security.  The premium paid to the writer
is in consideration for undertaking the obligation under the option contract.  A
put option for a particular security gives the purchaser the right to sell, and
the writer the option to buy, the security at the stated exercise price at any
time prior to the expiration date of the option, regardless of the market price
of the security.

     The Funds will write call options only if they are "covered."  In the case
of a call option on a security or currency, the option is "covered" if a Fund
owns the instrument underlying the call or has an absolute and immediate right
to acquire that instrument without additional cash consideration (or, if
additional cash consideration is required, cash, U.S. Government securities or
other liquid high grade debt obligations, in such amount are held in a
segregated account by the Fund's custodian) upon conversion or exchange of other
securities held by it.  For a call option on an index, the option is covered if
a Fund maintains with its custodian a diversified portfolio of securities
comprising the index or liquid assets equal to the contract value.  A call
option is also covered if a Fund holds an offsetting call on the same instrument
or index as the call written.  The Funds will write put options only if they are
"secured" by liquid assets maintained in a segregated account by the Funds'
custodian in an amount not less than the exercise price of the option at all
times during the option period.

     Each Fund may buy put and call options and write covered call and secured
put options.  Options trading is a highly specialized activity which entails
greater than ordinary investment risk.  Options may be more volatile than the
underlying instruments, and therefore, on a percentage basis, an investment in
options may be subject to greater fluctuation than an investment in the
underlying instruments themselves.  Purchasing options is a specialized
investment technique that entails a substantial risk of a complete loss of the
amounts paid as premiums to the writer of the option.  If the Advisor is
incorrect in its forecast of market value or other factors when writing options,
the Fund would be in a worse position than it would have been had if it had not
written the option.  If a Fund wishes to sell an underlying instrument (in the
case of a covered call option) or liquidate assets in a segregated account (in
the case of a secured put option), the Fund must purchase an offsetting option
if available, thereby incurring additional transactions costs.

     Below is a description of some of the types of options in which the Funds
may invest.

     A stock index option is an option contract whose value is based on the
value of a stock index at some future point in time.  Stock indexes fluctuate
with changes in the market values of

                                       10
<PAGE>

the stocks included in the index. The effectiveness of purchasing or writing
stock index options will depend upon the extent to which price movements in a
Fund's investment portfolio correlate with price movements of the stock index
selected. Accordingly, successful use by a Fund of options on stock indexes will
be subject to the Advisor's ability to correctly analyze movements in the
direction of the stock market generally or of particular industry or market
segments. When a Fund writes an option on a stock index, the Fund will place in
a segregated account with the Fund's custodian cash or liquid securities in an
amount at least equal to the market value of the underlying stock index and will
maintain the account while the option is open or otherwise will cover the
transaction.

     The Funds may invest in stock index futures contracts and options on stock
index futures contracts.  A stock index futures contract is an agreement in
which one party agrees to deliver to the other an amount of cash equal to a
specific dollar amount multiplied by the difference between the value of a
specific stock index at the close of the last trading day of the contract and
the price at which the agreement is made.  Stock index futures contracts may be
purchased to protect a Fund against an increase in the prices of stocks that
Fund intends to purchase.  The purchase of options on stock index futures
contracts are similar to other options contracts as described above, where a
Fund pays a premium for the option to purchase or sell a stock index futures
contract for a specified price at a specified date.  With options on stock index
futures contracts, a Fund risks the loss of the premium paid for the option.
The Funds may also invest in interest-rate futures contracts and options on
interest-rate futures contracts.  These securities are similar to stock index
futures contracts and options on stock index futures contracts, except they
derive their price from an underlying interest rate rather than a stock index.

     Interest-rate and index swaps involve the exchange by a Fund with another
party of their respective commitments to pay or receive interest (for example,
an exchange of floating-rate payments for fixed-rate payments).  Index swaps
involve the exchange by a Fund with another party of cash flows based upon the
performance of an index of securities.  Interest-rate swaps involve the exchange
by a Fund with another party of cash flows based upon the performance of a
specified interest rate.  In each case, the exchange commitments can involve
payments to be made in the same currency or in different currencies.  The Funds
will usually enter into swaps on a net basis.  In so doing, the two payment
streams are netted out, with a Fund receiving or paying, as the case may be,
only the net amount of the two payments.  If a Fund enters into a swap, it will
maintain a segregated account on a gross basis, unless the contract provides for
a segregated account on a net basis.  The risk of loss with respect to swaps
generally is limited to the net amount of payments that a Fund is contractually
obligated to make.  There is also a risk of a default by the other party to a
swap, in which case a Fund may not receive net amount of payments that the Fund
contractually is entitled to receive.

     Future Developments.  The Funds may take advantage of opportunities in the
areas of options and futures contracts and options on futures contracts and any
other derivative investments which are not presently contemplated for use by the
Funds or which are not currently available but which may be developed, to the
extent such opportunities are both consistent with the Funds' investment
objective and legally permissible for a Fund.  Before entering into such
transactions or making any such investment, a Fund would provide appropriate
disclosure in its Prospectus or this SAI.

                                       11
<PAGE>

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds, except the International Equity Fund, may purchase floating- and
variable-rate obligations such as demand notes and bonds.  Variable-rate demand
notes include master demand notes that are obligations that permit a Fund to
invest fluctuating amounts, which may change daily without penalty, pursuant to
direct arrangements between the Fund, as lender, and the borrower.  The interest
rate on a floating-rate demand obligation is based on a known lending rate, such
as a bank's prime rate, and is adjusted automatically each time such rate is
adjusted.  The interest rate on a variable-rate demand obligation is adjusted
automatically at specified intervals.  The issuer of such obligations ordinarily
has a right, after a given period, to prepay in its discretion the outstanding
principal amount of the obligations plus accrued interest upon a specified
number of days notice to the holders of such obligations.  Frequently, such
obligations are secured by letters of credit or other credit support
arrangements provided by banks.

     There generally is no established secondary market for these obligations
because they are direct lending arrangements between the lender and borrower.
Accordingly, where these obligations are not secured by letters of credit or
other credit support arrangements, a Fund's right to redeem is dependent on the
ability of the borrower to pay principal and interest on demand.  Such
obligations frequently are not rated by credit rating agencies and each Fund may
invest in obligations which are not so rated only if the Advisor determines that
at the time of investment the obligations are of comparable quality to the other
obligations in which such Fund may invest.  The Advisor, on behalf of each Fund,
considers on an ongoing basis the creditworthiness of the issuers of the
floating- and variable-rate demand obligations in such Fund's portfolio.  No
Fund will invest more than 15% of the value of its total net assets in floating-
or variable-rate demand obligations whose demand feature is not exercisable
within seven days.  Such obligations may be treated as liquid, if an active
secondary market exists.  Floating- and variable-rate instruments are subject to
interest-rate risk and credit risk.

     The floating- and variable-rate instruments that the Funds may purchase
include certificates of participation in such instruments.

     Foreign Obligations and Securities
     ----------------------------------

     The Equity Index, Equity Value and International Equity Funds may invest in
foreign securities through American Depositary Receipts ("ADRs"), Canadian
Depositary Receipts ("CDRs"), European Depositary Receipts ("EDRs"),
International Depositary Receipts ("IDRs") and Global Depositary Receipts
("GDRs") or other similar securities convertible into securities of foreign
issuers.  These securities may not necessarily be denominated in the same
currency as the securities into which they may be converted.  ADRs (sponsored or
unsponsored) are receipts typically issued by a U.S. bank or trust company and
traded on a U.S. stock exchange, and CDRs are receipts typically issued by a
Canadian bank or trust company that evidence ownership of underlying foreign
securities.  Issuers of unsponsored ADRs are not contractually obligated to
disclose material information in the U.S. and, therefore, such information may
not correlate to the market value of the unsponsored ADR.  EDRs and IDRs are
receipts typically issued by European banks and trust companies, and GDRs are
receipts issued by either a U.S. or non-U.S. banking institution, that evidence
ownership of the underlying foreign securities.  Generally, ADRs in

                                       12
<PAGE>

registered form are designed for use in U.S. securities markets and EDRs and
IDRs in bearer form are designed primarily for use in Europe. Each Fund may not
invest 25% or more of its assets in foreign obligations.

     For temporary defensive purposes, Funds may invest in fixed income
securities of non-U.S. governmental and private issuers.  Such investments may
include bonds, notes, debentures and other similar debt securities, including
convertible securities.

     Investments in foreign obligations involve certain considerations that are
not typically associated with investing in domestic securities.  There may be
less publicly available information about a foreign issuer than about a domestic
issuer.  Foreign issuers also are not generally subject to the same accounting,
auditing and financial reporting standards or governmental supervision as
domestic issuers.  In addition, with respect to certain foreign countries, taxes
may be withheld at the source under foreign tax laws, and there is a possibility
of expropriation or confiscatory taxation, political, social and monetary
instability or diplomatic developments that could adversely affect investments
in, the liquidity of, and the ability to enforce contractual obligations with
respect to, securities of issuers located in those countries.

     Investment income on certain foreign securities in which a Fund may invest
may be subject to foreign withholding or other taxes that could reduce the
return on these securities.  Tax treaties between the United States and foreign
countries, however, may reduce or eliminate the amount of foreign taxes to which
the Fund would be subject.

     Forward Commitments, When-Issued Purchases and Delayed-Delivery
     ---------------------------------------------------------------
Transactions
- ------------

     Each Fund may purchase or sell securities on a when-issued or delayed-
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time.  Securities purchased
or sold on a when-issued, delayed-delivery or forward commitment basis involve a
risk of loss if the value of the security to be purchased declines, or the value
of the security to be sold increases, before the settlement date.

     Each Fund will segregate cash, U.S. Government obligations or other high-
quality debt instruments in an amount at least equal in value to the Fund's
commitments to purchase when-issued securities.  If the value of these assets
declines, the Fund will segregate additional liquid assets on a daily basis so
that the value of the segregated assets is equal to the amount of such
commitments.

     Illiquid Securities
     -------------------

     The Funds may invest in securities not registered under the 1933 Act and
other securities subject to legal or other restrictions on resale.  Illiquid
securities may be difficult to sell promptly at an acceptable price.  Delay or
difficulty in selling securities may result in a loss or be costly to a Fund.

                                       13
<PAGE>

     Loans of Portfolio Securities
     -----------------------------

     Each Fund may lend its portfolio securities to brokers, dealers and
financial institutions, provided:  (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at least equal to the
current market value of the securities loaned; (2) the Fund may at any time call
the loan and obtain the return of the securities loaned within five business
days; (3) the Fund will receive any interest or dividends paid on the loaned
securities; and (4) the aggregate market value of securities loaned will not at
any time exceed the limits established by the 1940 Act.

     A Fund will earn income for lending its securities because cash collateral
pursuant to these loans will be invested in short-term money market instruments.
In connection with lending securities, a Fund may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide additional collateral.  In either case, a Fund could experience
delays in recovering securities or collateral or could lose all or part of the
value of the loaned securities.  Although voting rights, or rights to consent,
attendant to securities on loan pass to the borrower, such loans may be called
at any time and will be called so that the securities may be voted by a Fund if
a material event affecting the investment is to occur.  A Fund may pay a portion
of the interest or fees earned from securities lending to a borrower or placing
broker.  Borrowers and placing brokers may not be affiliated, directly or
indirectly, with Wells Fargo Bank, BGFA, Stephens Inc. or any of their
affiliates.

     Money Market Instruments and Temporary Investments
     --------------------------------------------------

     The Funds may invest in the following types of high quality money market
instruments that have remaining maturities not exceeding one year: (i) U.S.
Government obligations; (ii) negotiable certificates of deposit, bankers'
acceptances and fixed time deposits and other obligations of domestic banks
(including foreign branches) that have more than $1 billion in total assets at
the time of investment and are members of the Federal Reserve System or are
examined by the Comptroller of the Currency or whose deposits are insured by the
FDIC; (iii) commercial paper rated at the date of purchase "Prime-1" by Moodys
or "A-1" or "A-1--" by S&P, or, if unrated, of comparable quality as determined
by the Advisor; and (iv) repurchase agreements.  The Funds also may invest in
short-term U.S. dollar-denominated obligations of foreign banks (including U.S.
branches) that at the time of investment: (i) have more than $10 billion, or the
equivalent in other currencies, in total assets; (ii) are among the 75 largest
foreign banks in the world as determined on the basis of assets; (iii) have
branches or agencies in the United States; and (iv) in the opinion of the
Advisor, are of comparable quality to obligations of U.S. banks which may be
purchased by the Funds.

     Letters of Credit.  Certain of the debt obligations (including certificates
of participation, commercial paper and other short-term obligations) which the
Funds may purchase may be backed by an unconditional and irrevocable letter of
credit of a bank, savings and loan association or insurance company which
assumes the obligation for payment of principal and interest in the event of
default by the issuer.  Only banks, savings and loan associations and

                                       14
<PAGE>

insurance companies which, in the opinion of the Advisor, are of comparable
quality to issuers of other permitted investments of the Fund may be used for
letter of credit-backed investments.

     Repurchase Agreements.  A Fund may enter into repurchase agreements,
wherein the seller of a security to the Fund agrees to repurchase that security
from the Fund at a mutually agreed upon time and price.  A Fund may enter into
repurchase agreements only with respect to securities that could otherwise be
purchased by the Fund.  All repurchase agreements will be fully collateralized
at 102% based on values that are marked to market daily.  The maturities of the
underlying securities in a repurchase agreement transaction may be greater than
twelve months, although the maximum term of a repurchase agreement will always
be less than twelve months.  If the seller defaults and the value of the
underlying securities has declined, a Fund may incur a loss.  In addition, if
bankruptcy proceedings are commenced with respect to the seller of the security,
the Fund's disposition of the security may be delayed or limited.

     The Funds may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 15% of a Fund's total net assets
would be invested in repurchase agreements with maturities of more than seven
days, restricted securities and illiquid securities.  The Funds may not enter
into a repurchase agreement with a maturity of more than seven days, if, as a
result, more than 15% of the market value of a Fund's total net assets would be
invested in repurchase agreements with maturities of more than seven days,
restricted securities and illiquid securities.  A Fund will only enter into
repurchase agreements with primary broker/dealers and commercial banks that meet
guidelines established by the Board of Trustees and that are not affiliated with
the investment Advisor.  The Funds may participate in pooled repurchase
agreement transactions with other funds advised by the Advisor.

     Mortgage-Related and Other Asset-Backed Securities
     --------------------------------------------------

     The Asset Allocation and Income Equity Funds may invest in mortgage-related
securities.  Mortgage pass-through securities are securities representing
interests in "pools" of mortgages in which payments of both interest and
principal on the securities are made monthly, in effect "passing through"
monthly payments made by the individual borrowers on the residential mortgage
loans which underlie the securities (net of fees paid to the issuer or guarantor
of the securities).  Early repayment of principal on mortgage pass-through
securities may expose a Fund to a lower rate of return upon reinvestment of
principal.  Also, if a security subject to prepayment has been purchased at a
premium, in the event of prepayment the value of the premium would be lost.
Like other fixed-income securities, when interest rates rise, the value of a
mortgage-related security generally will decline; however, when interest rates
decline, the value of mortgage-related securities with prepayment features may
not increase as much as other fixed-income securities.  Payment of principal and
interest on some mortgage pass-through securities (but not the market value of
the securities themselves) may be guaranteed by the full faith and credit of the
U.S. Government or its agencies or instrumentalities.  Mortgage pass-through
securities created by non-government issuers (such as commercial banks, savings
and loan institutions, private mortgage insurance companies, mortgage bankers
and other secondary market issuers) may be supported by various forms of
insurance or guarantees, including individual loan, title, pool and hazard
insurance, and letters of credit, which may be issued by governmental entities,
private insurers or the mortgage poolers.

                                       15
<PAGE>

     The Funds may also invest in investment grade Collateralized Mortgage
Obligations ("CMOs"). CMOs may be collateralized by whole mortgage loans but are
more typically collateralized by portfolios of mortgage pass-through securities
guaranteed by the Government National Mortgage Association ("GNMA"), the Federal
Home Loan Mortgage Corporation ("FHLMC") or the Federal National Mortgage
Association (" FNMA"). CMOs are structured into multiple classes, with each
class bearing a different stated maturity. Payments of principal, including
prepayments, are first returned to investors holding the shortest maturity
class; investors holding the longer maturity classes receive principal only
after the first class has been retired. As new types of mortgage-related
securities are developed and offered to investors, the Advisor will, consistent
with a Fund's investment objective, policies and quality standards, consider
making investments in such new types of mortgage-related securities.

     There are risks inherent in the purchase of mortgage-related securities.
For example, these securities are subject to a risk that default in payment will
occur on the underlying mortgages. In addition to default risk, these securities
are subject to the risk that prepayment on the underlying mortgages will occur
earlier or later or at a lessor or greater rate than expected. To the extent
that the Advisor's assumptions about prepayments are inaccurate, these
securities may expose the Funds to significantly greater market risks than
expected.

     Other Asset-Backed Securities. The Funds may purchase asset-backed
securities unrelated to mortgage loans. These asset-backed securities may
consist of undivided fractional interests in pools of consumer loans or
receivables held in trust. Examples include certificates for automobile
receivables (CARS) and credit card receivables (CARDS). Asset-backed securities
are dependent upon payment of the consumer loans or receivables by individuals,
and the certificate holder frequently has no recourse to the entity that
originated the loans or receivables. The actual maturity and realized yield will
vary based upon the prepayment experience of the underlying asset pool and
prevailing interest rates at the time of prepayment. Asset-backed securities are
relatively new instruments and may be subject to greater risk of default during
periods of economic downturn than other instruments. Also, the secondary market
for certain asset-backed securities may not be as liquid as the market for other
types of securities, which could result in a Fund experiencing difficulty in
valuing or liquidating such securities.

     Other Investment Companies
     --------------------------

     The Funds may invest in shares of other open-end management investment
companies, up to the limits prescribed in Section 12(d) of the 1940 Act. Under
the 1940 Act, a Fund's investment in such securities currently is limited to,
subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5% of such Fund's net assets with respect to any one
investment company and (iii) 10% of such Fund's net assets in aggregate. Other
investment companies in which the Funds invest can be expected to charge fees
for operating expenses such as investment Advisory and administration fees, that
would be in addition to those charged by the Funds.

                                       16
<PAGE>

     Privately Issued Securities
     ---------------------------

     The Funds may invest in privately issued securities, including those which
may be resold only in accordance with Rule 144A under the Securities Act of 1933
("Rule 144A Securities"). Rule 144A Securities are restricted securities that
are not publicly traded. Accordingly, the liquidity of the market for specific
Rule 144A Securities may vary. Delay or difficulty in selling such securities
may result in a loss to a Fund. Privately issued or Rule 144A securities that
are determined by the investment Advisor to be "illiquid" are subject to the
Funds' policy of not investing more than 15% of its net assets in illiquid
securities. The investment Advisor, under guidelines approved by Board of
Trustees of the Trust, will evaluate the liquidity characteristics of each Rule
144A Security proposed for purchase by a Fund on a case-by-case basis and will
consider the following factors, among others, in their evaluation: (1) the
frequency of trades and quotes for the Rule 144A Security; (2) the number of
dealers willing to purchase or sell the Rule 144A Security and the number of
other potential purchasers; (3) dealer undertakings to make a market in the Rule
144A Security; and (4) the nature of the Rule 144A Security and the nature of
the marketplace trades (e.g., the time needed to dispose of the Rule 144A
Security, the method of soliciting offers and the mechanics of transfer).

     Unrated Investments
     -------------------

     The Funds may purchase instruments that are not rated if, in the opinion of
the Advisor, such obligations are of investment quality comparable to other
rated investments that are permitted to be purchased by such Fund. After
purchase by a Fund, a security may cease to be rated or its rating may be
reduced below the minimum required for purchase by the Fund. Neither event will
require a sale of such security by the Fund. To the extent the ratings given by
Moodys or S&P may change as a result of changes in such organizations or their
rating systems, a Fund will attempt to use comparable ratings as standards for
investments in accordance with the investment policies contained in its
Prospectus and in this SAI. The ratings of Moodys and S&P are more fully
described in the SAI Appendix.

     U.S. Government Obligations
     ---------------------------

     The Funds may invest in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government obligations").
Payment of principal and interest on U.S. Government obligations (i) may be
backed by the full faith and credit of the United States (as with U.S. Treasury
bills and GNMA certificates) or (ii) may be backed solely by the issuing or
guaranteeing agency or instrumentality itself (as with FNMA notes). In the
latter case investors must look principally to the agency or instrumentality
issuing or guaranteeing the obligation for ultimate repayment, which agency or
instrumentality may be privately owned. There can be no assurance that the U.S.
Government will provide financial support to its agencies or instrumentalities
where it is not obligated to do so. In addition, U.S. Government obligations are
subject to fluctuations in market value due to fluctuations in market interest
rates. As a general matter, the value of debt instruments, including U.S.
Government obligations, declines when market interest rates increase and rises
when market interest rates decrease. Certain types of U.S. Government
obligations are subject to fluctuations in yield or value due to their structure
or contract terms.

                                       17
<PAGE>

     Warrants
     --------

     The Diversified Equity, Growth Equity, Equity Index, Equity Value and
International Equity Funds may each invest up to 5% of its net assets at the
time of purchase in warrants (other than those that have been acquired in units
or attached to other securities), and not more than 2% of its net assets in
warrants which are not listed on the New York or American Stock Exchange.
Warrants represent rights to purchase securities at a specific price valid for a
specific period of time. The prices of warrants do not necessarily correlate
with the prices of the underlying securities. A Fund may only purchase warrants
on securities in which the Fund may invest directly.

     Nationally Recognized Statistical Ratings Organizations
     -------------------------------------------------------

     The ratings of Moodys Investors Service, Inc., Standard & Poor's Ratings
Group, Division of McGraw Hill, Duff & Phelps Credit Rating Co., Fitch Investors
Service, Inc. Thomson Bank Watch and IBCA Inc. represent their opinions as to
the quality of debt securities. It should be emphasized, however, that ratings
are general and not absolute standards of quality, and debt securities with the
same maturity, interest rate and rating may have different yields while debt
securities of the same maturity and interest rate with different ratings may
have the same yield. Subsequent to purchase by a Fund, an issue of debt
securities may cease to be rated or its rating may be reduced below the minimum
rating required for purchase by a Fund. The Advisor will consider such an event
in determining whether the Fund involved should continue to hold the obligation.

                                  MANAGEMENT

     The following information supplements, and should be read in conjunction

     Each of the Trustees and Officers listed above, act in the identical
capacities for Wells Fargo Variable Trust and Wells Fargo Core Trust
(collectively the "Fund Complex"). Trustees are compensated annually by the
Trust and by all the registrants in each fund complex they serve beginning
September 17, 1999, and beginning March 26, 1999, receive a per-meeting fee of
$250. Trustees also are reimbursed for all out-of-pocket expenses relating to
attendance at board meetings. Each of the Trustees and Officers of the Trust
serves in the identical capacity as trustees and/or officers of each registered
open-end management investment company in the Fund Complex. The Trustees are
compensated by other

companies and trusts within a fund complex for their services as
directors/trustees to such companies and trusts. Currently the Trustees do not
receive any retirement benefits or deferred compensation from the Trust or any
other member of each fund complex.

     As of the date of this SAI, Trustees and officers of the Trust, as a group,
beneficially owned less than 1% of the outstanding shares of the Trust.

     Administrator. The Trust has retained Wells Fargo Bank as Administrator on
     -------------
behalf of each Fund. Under the Administration Agreement between Wells Fargo Bank
and the Trust, Wells Fargo Bank shall provide as administration services, among
other things: (i) general supervision of the Funds' operations, including
coordination of the services performed by each Fund's investment Advisor,
transfer agent, custodian, shareholder servicing agent(s), independent auditors
and legal counsel, regulatory compliance, including the compilation of
information for documents such as reports to, and filings with, the SEC and
state securities commissions; and preparation of proxy statements and
shareholder reports for each Fund; and (ii) general supervision relative to the
compilation of data required for the preparation of periodic reports distributed
to the Trust's officers and Board of Trustees. Wells Fargo Bank also furnish
office space and certain facilities required for conducting the Funds' business
together with ordinary clerical and bookkeeping services. The Administrator is
entitled to receive a fee of 0.15%, of the average daily net assets on an annual
basis of each Fund.

     Distributor. Stephens Inc. ("Stephens," the "Distributor"), located at 111
     -----------
Center Street, Little Rock, Arkansas 72201, serves as Distributor for the Funds.
The Funds have adopted a distribution plan (a "Plan") under Section 12(b) of the
1940 Act and Rule 12b-1 thereunder (the "Rule") for their Class B and Class C
shares. The Plan was adopted by the Trust's Board of Trustees, including a
majority of the Trustees who were not "interested persons" (as defined in the
1940 Act) of the Funds and who had no direct or indirect financial interest in
the operation of the Plan or in any agreement related to the Plan (the "Non-
Interested Trustees").

     Under the Plan and pursuant to the related Distribution Agreement, the
Class B and Class C shares of the Funds pay Stephens up to 0.75% of the average
daily net assets attributable to each Class as compensation for distribution-
related services or as reimbursement for distribution-related expenses.

     The actual fee payable to the Distributor by the above-indicated Funds and
Classes is determined, within such limits, from time to time by mutual agreement
between the Trust and the Distributor and will not exceed the maximum sales
charges payable by mutual funds sold by members of the National Association of
Securities Dealers, Inc. ("NASD") under the Conduct Rules of the NASD. The
Distributor may enter into selling agreements with one or more selling agents
(which may include Wells Fargo Bank and its affiliates) under which such agents
may receive compensation for distribution-related services from the Distributor,
including, but not limited to, commissions or other payments to such agents
based on the average daily net assets of Fund shares attributable to their
customers. The Distributor may retain any portion of the total distribution fee
payable thereunder to compensate it for distribution-related services provided
by it or to reimburse it for other distribution-related expenses.

                                       24

     General. The Plan will continue in effect from year to year if such
     -------
continuance is approved by a majority vote of both the Trustees of the Trust and
the Non-Interested Trustees. Any Distribution Agreement related to the Plan also
must be approved by such vote of the Trustees and the Non-Interested Trustees.
Such Agreement will terminate automatically if assigned, and may be terminated
at any time, without payment of any penalty, by a vote of a majority of the
outstanding voting securities of the relevant class of the Fund or by vote of a
majority of the Non-Interested Trustees on not more than 60 days' written
notice. The Plan may not be amended to increase materially the amounts payable
thereunder without the approval of a majority of the outstanding voting
securities of the Fund, and no material amendment to the Plan may be made except
by a majority of both the Trustees of the Trust and the Non-Interested Trustees.

     The Plan requires that the Treasurer of Trust shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Plan. The Rule also
requires that the selection and nomination of Trustees who are not "interested
persons" of the Trust be made by such disinterested Trustees.

     Wells Fargo Bank, an interested person (as that term is defined in Section
2(a)(19) of the 1940 Act) of the Trust, acts as a selling agent for the Funds'
shares pursuant to selling agreements with Stephens authorized under the Plan.
As a selling agent, Wells Fargo Bank has an indirect financial interest in the
operation of the Plan. The Board of Trustees has concluded that the Plan is
reasonably likely to benefit the Funds and their shareholders because the Plan
authorizes the relationships with selling agents, including Wells Fargo Bank,
that have previously developed distribution channels and relationships with the
retail customers that the Funds are designed to serve. These relationships and
distribution channels are believed by the Board to provide potential for
increased Fund assets and ultimately corresponding economic efficiencies (i.e.,
lower per-share transaction costs and fixed expenses) that are generated by
increased assets under management.

     Shareholder Servicing Agent.  The Funds have approved a Servicing Plan and
     ---------------------------
have entered into related Shareholder Servicing Agreements with financial
institutions, including Wells Fargo Bank. Under the agreements, Shareholder
Servicing Agents (including Wells Fargo Bank) agree to perform, as agents for
their customers, administrative services, with respect to Fund shares, which
include aggregating and transmitting shareholder orders for purchases, exchanges
and redemptions; maintaining shareholder accounts and records; and providing
such other related services as the Trust or a shareholder may reasonably
request. For providing shareholder services, a Servicing Agent is entitled to a
fee from the applicable Fund of up to 0.25% on an annualized basis, of the
average daily net assets of the class of shares owned of record or beneficially
by the customers of the Servicing Agent during the period for which payment is
being made. The amounts payable under the Shareholder Servicing Plan and
Agreements are shown below. The Servicing Plan and related Shareholder Servicing
Agreements were approved by the Trust's Board of Trustees and provide that a
Fund shall not be obligated to make any payments under such Plan or related
Agreements that exceed the maximum amounts payable under the Conduct Rules of
the NASD.

                                 [INSERT CHART]


     General.  The Servicing Plan will continue in effect from year to year if
     -------
such continuance is approved by a majority vote of the Trustees of the Trust,
including a majority of the Trustees who are not "interested persons" (as
defined in the 1940 Act) of the Funds ("Non-Interested Trustees"). Any form of
Servicing Agreement related to the Servicing Plan also must be approved by such
vote of the Trustees and the Non-Interested Trustees. Servicing Agreements may
be terminated at any time, without payment of any penalty, by a vote of a
majority of the Board of Trustees, including a majority of the Non-Interested
Trustees. No material amendment to the Servicing Plan or related Servicing
Agreements may be made except by a majority of both the Trustees of the Trust
and the Non-Interested Trustees.

     The Servicing Plan requires that the Administrator of the Trust shall
provide to the Trustees, and the Trustees shall review, at least quarterly, a
written report of the amounts expended (and purposes therefor) under the
Servicing Plan.

     Custodian.  Norwest Bank Minnesota, N.A. ("Norwest Bank") acts as Custodian
     ---------
for each Fund. The Custodian, among other things, maintains a custody account or
accounts in the name of each Fund, receives and delivers all assets for each
Fund upon purchase and upon sale or maturity, collects and receives all income
and other payments and distributions on account of the assets of each Fund and
pays all expenses of each Fund. For its services as Custodian, Norwest Bank is
entitled to receive fees as follows: .02% of the average daily net assets of
each Fund.

     Fund Accountant. Forum Financial Services, Inc. acts as Fund Accountant
     ---------------
for the Funds. The Fund Accountant, among other things, computes net asset
values on a daily basis and performance calculations on a regular basis and as
requested by the Funds. For providing such services, Forum is entitled to
receive a fee of [___.]

     Transfer and Dividend Disbursing Agent. State Street Bank, acting through
     --------------------------------------
its affiliate Boston Financial Data Services ("BFDS"), acts as Transfer and
Dividend Disbursing Agent for the Funds. For providing such services, BFDS is
entitled to receive a per-account fee of [.04% of the average daily net assets
of each such account on an annual basis].

                           PERFORMANCE CALCULATIONS

     The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown. Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

                                       26
<PAGE>

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

     Performance information for a Fund or Class of shares in a Fund may be
useful in reviewing the performance of such Fund or Class of shares and for
providing a basis for comparison with investment alternatives. The performance
of a Fund and the performance of a Class of shares in a Fund, however, may not
be comparable to the performance from investment alternatives because of
differences in the foregoing variables and differences in the methods used to
value portfolio securities, compute expenses and calculate performance.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

     Average Annual Total Return: The Funds may advertise certain total return
     ---------------------------
information. As and to the extent required by the SEC, an average annual
compound rate of return ("T") is computed by using the redeemable value at the
end of a specified period ("ERV") of a hypothetical initial investment ("P")
over a period of years ("n") according to the following formula: P(1+T)n=ERV.

     Cumulative Total Return: In addition to the above performance information,
     -----------------------
each Fund may also advertise the cumulative total return of the Fund.
Cumulative total return is based on the overall percentage change in value of a
hypothetical investment in the Fund, assuming all Fund dividends and capital
gain distributions are reinvested, without reflecting the effect of any sales
charge that would be paid by an investor, and is not annualized.

     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Trust may quote the performance or price-
earning ratio of a Fund or Class in advertising and other types of literature as
compared to the performance of the S&P Index, the Dow Jones Industrial Average,
the Lehman Brothers 20+ Treasury Index, the Lehman Brothers 5-7 Year Treasury
Index, Donoghue's Money Fund Averages, Real Estate Investment Averages (as
reported by the National Association of Real Estate Investment Trusts), Gold
Investment Averages (provided by World Gold Council), Bank Averages (which are
calculated from figures supplied by the U.S. League of Savings Institutions
based on effective annual rates of interest on both passbook and certificate
accounts), average annualized certificate of deposit rates (from the Federal
Reserve G-13 Statistical Releases or the Bank Rate Monitor), the Salomon One
Year Treasury Benchmark Index, the Consumer Price Index (as published by the
U.S. Bureau of Labor Statistics), other managed or unmanaged indices or
performance data of bonds, municipal securities, stocks or government securities
(including data provided by Ibbotson Associates), or by other services,
companies, publications or persons who monitor mutual funds on overall
performance or other criteria. The S&P Index and the Dow Jones Industrial
Average are unmanaged indices of selected common stock prices. The performance
of the Funds or a Class also may be compared to that of other mutual funds
having similar objectives. This comparative performance could be expressed as a
ranking prepared by Lipper Analytical Services, Inc., CDA Investment
Technologies, Inc., Bloomberg Financial Markets or Morningstar, Inc.,
independent

                                       27
<PAGE>

services which monitor the performance of mutual funds. The Funds' performance
will be calculated by relating net asset value per share at the beginning of a
stated period to the net asset value of the investment, assuming reinvestment of
all gains distributions and dividends paid, at the end of the period. The Funds'
comparative performance will be based on a comparison of yields, as described
above, or total return, as reported by Lipper, Survey Publications, Donoghue or
Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a Class with that of competitors. Of course, past
performance cannot be a guarantee of future results. The Trust also may include,
from time to time, a reference to certain marketing approaches of the
Distributor, including, for example, a reference to a potential shareholder
being contacted by a selected broker or dealer. General mutual fund statistics
provided by the Investment Company Institute may also be used.

     The Trust also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
the Fund: (i) the Consumer Price Index may be used to assess the real rate of
return from an investment in a Fund; (ii) other government statistics,
including, but not limited to, The Survey of Current Business, may be used to
illustrate investment attributes of a Fund or the general economic, business,
investment, or financial environment in which a Fund operates; (iii) the effect
of tax-deferred compounding on the investment returns of a Fund, or on returns
in general, may be illustrated by graphs, charts, etc., where such graphs or
charts would compare, at various points in time, the return from an investment
in a Fund (or returns in general) on a tax-deferred basis (assuming reinvestment
of capital gains and dividends and assuming one or more tax rates) with the
return on a taxable basis; and (iv) the sectors or industries in which a Fund
invests may be compared to relevant indices of stocks or surveys (e.g., S&P
Industry Surveys) to evaluate a Fund's historical performance or current or
potential value with respect to the particular industry or sector.

     In addition, the Trust also may use, in advertisements and other types of
literature, information and statements: (1) showing that bank savings accounts
offer a guaranteed return of principal and a fixed rate of interest, but no
opportunity for capital growth; and (2) describing Wells Fargo Bank, and its
affiliates and predecessors, as one of the first investment managers to advise
investment accounts using asset allocation and index strategies. The Trust also
may include in advertising and other types of literature information and other
data from reports and studies prepared by the Tax Foundation, including
information regarding federal and state tax levels and the related "Tax Freedom
Day."

     The Trust also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by an NRSRO, such as Standard & Poor's
Corporation. Such rating would assess the creditworthiness of the investments
held by the Fund. The assigned rating would not be a recommendation to purchase,
sell or hold the Fund's shares since the rating would not comment on the market
price of the Fund's shares or the suitability of the Fund for a particular
investor. In addition, the assigned rating would be subject to change,
suspension or withdrawal as a result of changes in, or unavailability of,
information relating to the Fund or its investments. The Trust may compare the
Fund's performance with other investments which are

                                       28
<PAGE>

assigned ratings by NRSROs. Any such comparisons may be useful to investors who
wish to compare the Fund's past performance with other rated investments.

     From time to time, the Funds may use the following statements, or
variations thereof, in advertisements and other promotional materials: "Wells
Fargo Bank, as a Shareholder Servicing Agent for the Wells Fargo Funds Trust
Funds, provides various services to its customers that are also shareholders of
the Funds. These services may include access to Wells Fargo Funds Trust Funds'
account information through Automated Teller Machines (ATMs), the placement of
purchase and redemption requests for shares of the Funds through ATMs and the
availability of combined Wells Fargo Bank and Stagecoach Funds account
statements."

     The Trust also may disclose, in advertising and other types of literature,
information and statements that Wells Capital Management (formerly "Wells Fargo
Investment Management"), a division of Wells Fargo Bank, is listed in the top
100 by Institutional Investor magazine in its July 1997 survey "America's Top
300 Money Managers." This survey ranks money managers in several asset
categories. The Trust may also disclose in advertising and other types of sales
literature the assets and categories of assets under management by the Trust's
investment advisor. The Trust may also disclose in advertising and other types
of sales literature the assets and categories of assets under management by a
fund's investment advisor or sub-advisor and the total amount of assets and
mutual fund assets managed by Wells Fargo Bank. As of December 31, 1998, Wells
Fargo Bank and its affiliates provided investment Advisory services for
approximately $202 billion in assets.

     The Trust also may discuss in advertising and other types of literature the
features, terms and conditions of Wells Fargo Bank accounts through which
investments in the Funds may be made via a "sweep" arrangement, including,
without limitation, the Managed Sweep Account, Money Market Checking Account,
California Tax-Free Money Market Checking Account, Money Market Access Account
and California Tax-Free Money Market Access Account (collectively, the "Sweep
Accounts"). Such advertisements and other literature may include, without
limitation, discussions of such terms and conditions as the minimum deposit
required to open a Sweep Account, a description of the yield earned on shares of
the Funds through a Sweep Account, a description of any monthly or other service
charge on a Sweep Account and any minimum required balance to waive such service
charges, any overdraft protection plan offered in connection with a Sweep
Account, a description of any ATM or check privileges offered in connection with
a Sweep Account and any other terms, conditions, features or plans offered in
connection with a Sweep Account. Such advertising or other literature may also
include a discussion of the advantages of establishing and maintaining a Sweep
Account, and may include statements from customers as to the reasons why such
customers have established and maintained a Sweep Account.

     The Trust may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels"). Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees. Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely

                                       29
<PAGE>

through Electronic Channels. Advertising and other literature may disclose that
Wells Fargo Bank may maintain Web sites, pages or other information sites
accessible through Electronic Channels (an "Information Site") and may describe
the contents and features of the Information Site and instruct investors on how
to access the Information Site and open a Sweep Account. Advertising and other
literature may also disclose the procedures employed by Wells Fargo Bank to
secure information provided by investors, including disclosure and discussion of
the tools and services for accessing Electronic Channels. Such advertising or
other literature may include discussions of the advantages of establishing and
maintaining a Sweep Account through Electronic Channels and testimonials from
Wells Fargo Bank customers or employees and may also include descriptions of
locations where product demonstrations may occur. The Trust may also disclose
the ranking of Wells Fargo Bank as one of the largest money managers in the
United States.

     The Trust also may disclose in sales literature the distribution rate on
the shares of a Fund. Distribution rate, which may be annualized, is the amount
determined by dividing the dollar amount per share of the most recent dividend
by the most recent NAV or maximum offering price per share as of a date
specified in the sales literature. Distribution rate will be accompanied by the
standard 30-day yield as required by the SEC.

                       DETERMINATION OF NET ASSET VALUE

     Net asset value per share for each class of the Funds is determined as of
the close of regular trading (currently 1:00 p.m. Pacific time/3:00 p.m. Central
time) on each day the New York Stock Exchange ("NYSE") is open for business.
Expenses and fees, including Advisory fees, are accrued daily and are taken into
account for the purpose of determining the net asset value of the Funds' shares.

     Securities of a Fund for which market quotations are available are valued
at latest prices. Any security for which the primary market is an exchange is
valued at the last sale price on such exchange on the day of valuation or, if
there was no sale on such day, the latest bid price quoted on such day. In the
case of other securities, including U.S. Government securities but excluding
money market instruments maturing in 60 days or less, the valuations are based
on latest quoted bid prices. Money market instruments and debt securities
maturing in 60 days or less are valued at amortized cost. The assets of a Fund,
other than money market instruments or debt securities maturing in 60 days or
less, are valued at latest quoted bid prices. Futures contracts will be marked
to market daily at their respective settlement prices determined by the relevant
exchange. Prices may be furnished by a reputable independent pricing service
approved by the Trust's Board of Trustees. Prices provided by an independent
pricing service may be determined without exclusive reliance on quoted prices
and may take into account appropriate factors such as institutional-size trading
in similar groups of securities, yield, quality, coupon rate, maturity, type of
issue, trading characteristics and other market data. All other securities and
other assets of a Fund for which current market quotations are not readily
available are valued at fair value as determined in good faith by the Trust's
Board of Trustees and in accordance with procedures adopted by the Trustees.

                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

     Shares may be purchased on any day a Fund is open for business.  Each Fund
is open for business each day the NYSE is open for trading (a "Business Day").
Currently, the NYSE is closed 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 a "Holiday"). When any Holiday falls on
a weekend, the NYSE typically is closed on the weekday immediately before or
after such Holiday.

     Payment for shares may, in the discretion of the Advisor, be made in the
form of securities that are permissible investments for the Fund.  For further
information about this form of payment please contact Stephens.  In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that a Fund receives satisfactory assurances
that (i) it will have good and marketable title to the securities received by
it; (ii) that the securities are in proper form for transfer to the Fund; and
(iii) adequate information will be provided concerning the basis and other
matters relating to the securities.

     Under the 1940 Act, the Fund may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit.  The Trust may suspend redemption rights or postpone redemption
payments for such periods as are permitted under the 1940 Act.  The Trust may
also redeem shares involuntarily or make payment for redemption in securities or
other property if it appears appropriate to do so in light of the Trust's
responsibilities under the 1940 Act.  In addition, the Trust may redeem shares
involuntarily to reimburse the Fund for any losses sustained by reason of the
failure of a shareholders to make full payment for shares purchased or to
collect any charge relating to a transaction effected for the benefit of a
shareholder which is applicable to shares of the Fund as provided from time to
time in the Prospectus.

                            PORTFOLIO TRANSACTIONS

     The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities.  Subject to policies
established by the Trust's Board of Trustees, Wells Fargo Bank is responsible
for each Fund's portfolio decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Trust to obtain the best results
taking into account the dealer's general execution and operational facilities,
the type of transaction involved and other factors such as the dealer's risk in
positioning the securities involved.  While Wells Fargo Bank generally seeks
reasonably competitive spreads or commissions, the Funds will not necessarily be
paying the lowest spread or commission available.

     Purchases and sales of equity securities on a securities exchange are
effected through brokers who charge a negotiated commission for their services.
Orders may be directed to any

                                       31

broker including, to the extent and in the manner permitted by applicable law,
Stephens or Wells Fargo Securities Inc. In the over-the-counter market,
securities are generally traded on a "net" basis with dealers acting as
principal for their own accounts without a stated commission, although the price
of the security usually includes a profit to the dealer. In underwritten
offerings, securities are purchased at a fixed price that includes an amount of
compensation to the underwriter, generally referred to as the underwriter's
concession or discount.

     In placing orders for portfolio securities of a Fund, Wells Fargo Bank is
required to give primary consideration to obtaining the most favorable price and
efficient execution.  This means that Wells Fargo Bank will seek to execute each
transaction at a price and commission, if any, that provide the most favorable
total cost or proceeds reasonably attainable in the circumstances.  Commission
rates are established pursuant to negotiations with the broker based on the
quality and quantity of execution services provided by the broker in the light
of generally prevailing rates.  The allocation of orders among brokers and the
commission rates paid are reviewed periodically by the Board of Trustees.

     Wells Fargo Bank, as the Investment Advisor of each of the Funds, may, in
circumstances in which two or more dealers are in a position to offer comparable
results for a Fund portfolio transaction, give preference to a dealer that has
provided statistical or other research services to Wells Fargo Bank.  By
allocating transactions in this manner, Wells Fargo Bank is able to supplement
its research and analysis with the views and information of securities firms.
Information so received will be in addition to, and not in lieu of, the services
required to be performed by Wells Fargo Bank under the Advisory Contracts, and
the expenses of Wells Fargo Bank will not necessarily be reduced as a result of
the receipt of this supplemental research information.  Furthermore, research
services furnished by dealers through which Wells Fargo Bank places securities
transactions for a Fund may be used by Wells Fargo Bank in servicing its other
accounts, and not all of these services may be used by Wells Fargo Bank in
connection with advising the Funds.

     Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
     ------------------
when Wells Fargo Bank deems portfolio changes appropriate.  Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the best interests of the
Funds and their shareholders. The portfolio turnover rate is calculated by
dividing the lesser of purchases or sales of portfolio securities by the average
monthly value of the Fund's portfolio securities. For purposes of this
calculation, portfolio securities exclude all securities having a maturity when
purchased of one year or less.  Portfolio turnover generally involves some
expenses to the Funds, including brokerage commissions or dealer mark-ups and
other transaction costs on the sale of securities and the reinvestment in other
securities.  Portfolio turnover also can generate short-term capital gain tax
consequences.  Portfolio turnover rate is not a limiting factor when Wells Fargo
Bank deems portfolio changes appropriate.

     From time to time, Wells Fargo Bank and Stephens may waive fees from the
Fund in whole or in part.  Any such waiver will reduce expenses and,
accordingly, have a favorable impact on the Fund's performance.

                                 FUND EXPENSES

     Except for the expenses borne by Wells Fargo Bank and Stephens, the Trust
bears all costs of its operations, including the compensation of its Trustees
who are not affiliated with Stephens or Wells Fargo Bank or any of their
affiliates; Advisory, shareholder servicing and administration fees; payments
pursuant to any Plan; interest charges; taxes; fees and expenses of its
independent auditors, legal counsel, transfer agent and dividend disbursing
agent; expenses of redeeming shares; expenses of preparing and printing
prospectuses (except the expense of printing and mailing prospectuses used for
promotional purposes, unless otherwise payable pursuant to a Plan),
shareholders' reports, notices, proxy statements and reports to regulatory
agencies; insurance premiums and certain expenses relating to insurance
coverage; trade association membership dues; brokerage and other expenses
connected with the execution of portfolio transactions; fees and expenses of its
custodian, including those for keeping books and accounts and calculating the
NAV per share of the Fund; expenses of shareholders' meetings; expenses relating
to the issuance, registration and qualification of the Fund's shares; pricing
services, and any extraordinary expenses.  Expenses attributable to the Fund are
charged against  Fund assets.  General expenses of the Trust are allocated among
all of the funds of the Trust, including the Funds, in a manner proportionate to
the net assets of a Funds, on a transactional basis, or on such other basis as
the Trust's Board of Trustees deems equitable.

                             FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes."  The Prospectuses of each Fund
describe generally the tax treatment of distributions by the Funds.  This
section of the SAI includes additional information concerning Federal income
taxes.

     General.  The Trust intends to qualify each Fund as a regulated investment
     -------
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"), as long as such qualification is in the best interest of the Fund's
shareholders.  Each Fund will be treated as a separate entity for Federal income
tax purposes.  Thus, the provisions of the Code applicable to regulated
investment companies generally will be applied to each Fund, rather than to the
Trust as a whole.  In addition, net capital gains, net investment income, and
operating expenses will be determined separately for each Fund.  As a regulated
investment company, each Fund will not be taxed on its net investment income and
capital gains distributed to its shareholders.

     Qualification as a regulated investment company under the Code requires,
among other things, that each Fund (a) derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including, but not limited to, gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) diversify its holdings so that,
at the end of each quarter of the taxable year, (i) at least 50% of the market
value of the Fund's assets is represented by cash, government securities and
other securities limited with respect to any one issuer to an amount not greater
than 5% of the Fund's assets and

                                       33
<PAGE>

10% of the outstanding voting securities of such issuer, and (ii) not more than
25% of the value of its assets is invested in the securities of any one issuer
(other than U.S. Government obligations and the securities of other regulated
investment companies), or in two or more issuers which the Fund controls and
which are determined to be engaged in the same or similar trades or businesses.

     The Funds also must distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income (which, for this
purpose, includes net short-term capital gains) earned in each taxable year.  In
general, these distributions must actually or be deemed to be made in the
taxable year.  However, in certain circumstances, such distributions may be made
in the 12 months following the taxable year.  Furthermore, distributions
declared in October, November or December of one taxable year and paid by
January 31 of the following taxable year will be treated as paid by December 31
of the first taxable year.  The Funds intend to pay out substantially all of
their net investment income and net realized capital gains (if any) for each
year.

     In addition, a regulated investment company must, in general, derive less
than 30% of its gross income from the sale or other disposition of securities or
options thereon held for less than three months.  However, this restriction has
been repealed with respect to a regulated investment company's taxable years
beginning after August 5, 1997.

     Excise Tax.  A 4% nondeductible excise tax will be imposed on each Fund
     ----------
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

     Taxation of Fund Investments.  Except as provided herein, gains and losses
     ----------------------------
on the sale of portfolio securities by a Fund will generally be capital gains
and losses.  Such gains and losses will ordinarily be long-term capital gains
and losses if the securities have been held by the Fund for more than one year
at the time of disposition of the securities.

     Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by a Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

     If an option granted by a Fund lapses or is terminated through a closing
transaction, such as a repurchase by the Fund of the option from its holder, the
Fund will realize a short-term capital gain or loss, depending on whether the
premium income is greater or less than the amount paid by the Fund in the
closing transaction.  Some realized capital losses may be deferred if they
result from a position which is part of a "straddle," discussed below.  If
securities are sold by the Fund pursuant to the exercise of a call option
written by it, the Fund will add the premium received to the sale price of the
securities delivered in determining the amount of gain or loss on

                                       34
<PAGE>

the sale. If securities are purchased by a Fund pursuant to the exercise of a
put option written by it, such Fund will subtract the premium received from its
cost basis in the securities purchased.

     The amount of any gain or loss realized by a Fund on closing out a
regulated futures contract will generally result in a realized capital gain or
loss for Federal income tax purposes. Regulated futures contracts held at the
end of each fiscal year will be required to be "marked to market" for Federal
income tax purposes pursuant to Section 1256 of the Code.  In this regard, they
will be deemed to have been sold at market value. Sixty percent (60%) of any net
gain or loss recognized on these deemed sales, and sixty percent (60%) of any
net realized gain or loss from any actual sales, will generally be treated as
long-term capital gain or loss, and the remainder will be treated as short-term
capital gain or loss.  Transactions that qualify as designated hedges are
excepted from the "mark-to-market" rule and the "60%/40%" rule.

     Under Section 988 of the Code, a Fund generally will recognize ordinary
income or loss to the extent that gain or loss realized on the disposition of
portfolio securities is attributable to changes in foreign currency exchange
rates.  In addition, gain or loss realized on the disposition of a foreign
currency forward contract, futures contract, option or similar financial
instrument, or of foreign currency itself, will generally be treated as ordinary
income or loss.  The Funds will attempt to monitor Section 988 transactions,
where applicable, to avoid adverse Federal income tax impact.

     Offsetting positions held by a Fund involving certain financial forward,
futures or options contracts may be considered, for tax purposes, to constitute
"straddles."  "Straddles" are defined to include "offsetting positions" in
actively traded personal property.  The tax treatment of "straddles" is governed
by Section 1092 of the Code which, in certain circumstances, overrides or
modifies the provisions of Section 1256.  If a Fund were treated as entering
into "straddles" by engaging in certain financial forward, futures or option
contracts, such straddles could be characterized as "mixed straddles" if the
futures, forwards, or options comprising a part of such straddles were governed
by Section 1256 of the Code.  The Fund may make one or more elections with
respect to "mixed straddles."  Depending upon which election is made, if any,
the results with respect to the Fund may differ.  Generally, to the extent the
straddle rules apply to positions established by the Fund, losses realized by
the Fund may be deferred to the extent of unrealized gain in any offsetting
positions.  Moreover, as a result of the straddle and the conversion transaction
rules, short-term capital loss on straddle positions may be recharacterized as
long-term capital loss, and long-term capital gain may be characterized as
short-term capital gain or ordinary income.

     If a Fund enters into a "constructive sale" of any appreciated position in
stock, a partnership interest, or certain debt instruments, the Fund must
recognize gain (but not loss) with respect to that position.  For this purpose,
a constructive sale occurs when the Fund enters into one of the following
transactions with respect to the same or substantially identical property:  (i)
a short sale; (ii) an offsetting notional principal contract; or (iii) a futures
or forward contract.

     If a Fund purchases shares in a "passive foreign investment company"
("PFIC"), the Fund may be subject to Federal income tax and an interest charge
imposed by the IRS upon certain distributions from the PFIC or the Fund's
disposition of its PFIC shares.  If a Fund invests in a

                                       35
<PAGE>

PFIC, the Fund intends to make an available election to mark-to-market its
interest in PFIC shares. Under the election, the Fund will be treated as
recognizing at the end of each taxable year the difference, if any, between the
fair market value of its interest in the PFIC shares and its basis in such
shares. In some circumstances, the recognition of loss may be suspended. The
Fund will adjust its basis in the PFIC shares by the amount of income (or loss)
recognized. Although such income (or loss) will be taxable to the Fund as
ordinary income (or loss) notwithstanding any distributions by the PFIC, the
Fund will not be subject to Federal income tax or the interest charge with
respect to its interest in the PFIC under the election.

     Income and dividends received by the Funds from sources within foreign
countries may be subject to withholding and other taxes imposed by such
countries.

     Capital Gain Distributions.  Distributions which are designated by a Fund
     --------------------------
as capital gain distributions will be taxed to shareholders as long-term term
capital gain (to the extent such dividends do exceed the Fund's actual net
capital gains for the taxable year), regardless of how long a shareholder has
held Fund shares.  Such distributions will be designated as capital gain
distributions in a written notice mailed by the Fund to its shareholders not
later than 60 days after the close of the Fund's taxable year.

     Disposition of Fund Shares.  A disposition of Fund shares pursuant to a
     --------------------------
redemption (including a redemption in-kind) or an exchange will ordinarily
result in a taxable capital gain or loss, depending on the amount received for
the shares (or are deemed to be received in the case of an exchange) and the
cost of the shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred in acquiring the Fund's shares shall not be
taken into account (to the extent such previous sales charges do not exceed the
reduction in sales charges on the new purchase) for the purpose of determining
the amount of gain or loss on the disposition, but will be treated as having
been incurred in the acquisition of such other shares.  Also, any loss realized
on a redemption or exchange of shares of the Fund will be disallowed to the
extent that substantially identical shares are acquired within the 61-day period
beginning 30 days before and ending 30 days after the shares are disposed of.

     If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as a long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as a long-term capital loss to the extent of the designated capital gain
distribution.  In addition, if a shareholder holds Fund shares for six months or
less, any loss on the sale or exchange of those shares will be disallowed to the
extent of the amount of exempt-interest dividends received with respect to the
shares.  The Treasury Department is authorized to issue regulations reducing the
six months holding requirement to a period of not less than the greater of 31
days or the period between regular dividend distributions where a Fund regularly
distributes at least 90% of its net tax-exempt interest, if any.  No such
regulations have

                                       36
<PAGE>

been issued as of the date of this SAI. The loss disallowance rules described in
this paragraph do not apply to losses realized under a periodic redemption plan.

     Federal Income Tax Rates.  As of the printing of this SAI, the maximum
     ------------------------
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 20%; and the maximum corporate tax rate applicable to
ordinary income and net capital gain is 35% (marginal tax rates may be higher
for some corporations to reduce or eliminate the benefit of lower marginal
income tax rates).  Naturally, the amount of tax payable by an individual or
corporation will be affected by a combination of tax laws covering, for example,
deductions, credits, deferrals, exemptions, sources of income and other matters.

     Backup Withholding.  The Trust may be required to withhold, subject to
     ------------------
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, if the shareholder fails to certify that the Taxpayer
Identification Number ("TIN") provided is correct and that the shareholder is
not subject to backup withholding, or if the IRS notifies the Trust that the
shareholder's TIN is incorrect or that the shareholder is subject to backup
withholding.  Such tax withheld does not constitute any additional tax imposed
on the shareholder, and may be claimed as a tax payment on the shareholder's
Federal income tax return.  An investor must provide a valid TIN upon opening or
reopening an account.  Failure to furnish a valid TIN to the Trust could also
subject the investor to penalties imposed by the IRS.

     Corporate Shareholders.  Corporate shareholders of the Funds may be
     ----------------------
eligible for the dividends-received deduction on dividends distributed out of a
Fund's net investment income attributable to dividends received from domestic
corporations, which, if received directly by the corporate shareholder, would
qualify for such deduction.  A distribution by a Fund attributable to dividends
of a domestic corporation will only qualify for the dividends-received deduction
if (i) the corporate shareholder generally holds the Fund shares upon which the
distribution is made for at least 46 days during the 90 day period beginning 45
days prior to the date upon which the shareholder becomes entitled to the
distribution; and (ii) the Fund generally holds the shares of the domestic
corporation producing the dividend income for at least 46 days during the 90 day
period beginning 45 days prior to the date upon which the Fund becomes entitled
to such dividend income.

     Foreign Shareholders.  Under the Code, distributions of net investment
     --------------------
income by the Funds to a nonresident alien individual, foreign trust (i.e.,
trust which a U.S. court is able to exercise primary supervision over
administration of that trust and one or more U.S. persons have authority to
control substantial decisions of that trust), foreign estate (i.e., the income
of which is not subject to U.S. tax regardless of source), foreign corporation,
or foreign partnership (a "foreign shareholder") will be subject to U.S.
withholding tax (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend paid by the Fund to a foreign
shareholder is "effectively connected" with a U.S. trade or business (or, if an
income tax treaty applies, is attributable to a U.S. permanent establishment of
the foreign shareholder), in which

                                       37
<PAGE>

case the reporting and withholding requirements applicable to U.S. persons will
apply. Distributions of capital gains are generally not subject to tax
withholding.

     New Regulations.  On October 6, 1997, the Treasury Department issued new
     ---------------
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1999, subject to certain
transition rules.  Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders that will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax Advisors regarding the
New Regulations.

     Tax-Deferred Plans.  The shares of the Funds are available for a variety of
     ------------------
tax-deferred retirement and other plans, including Individual Retirement
Accounts ("IRA"), Simplified Employee Pension Plans ("SEP-IRA"), Savings
Incentive Match Plans for Employees ("SIMPLE plans"), Roth IRAs, and Education
IRAs, which permit investors to defer some of their income from taxes.
Investors should contact their selling agents for details concerning retirement
plans.

     Foreign Taxes.  Income and dividends received by the Fund from sources
     -------------
within foreign countries may be subject to withholding and other taxes imposed
by such countries.  Tax conventions between certain countries and the United
States may reduce or eliminate such taxes.  If more than 50% in value of a
regulated investment company's total assets at the close of its taxable year
consist of securities of non-U.S. corporations, the regulated investment company
will be eligible to file an election with the IRS pursuant to which the
regulated investment company may pass-through to its shareholders foreign taxes
paid by the regulated investment company, which may be claimed either as a
credit or deduction by the shareholders.  None of the Funds expects to qualify
for the election.

     Other Matters.  Investors should be aware that the investments to be made
     -------------
by the Funds may involve sophisticated tax rules that may result in income or
gain recognition by the Funds without corresponding current cash receipts.
Although the Funds will seek to avoid significant noncash income, such noncash
income could be recognized by the Funds, in which case the Funds may distribute
cash derived from other sources in order to meet the minimum distribution
requirements described above.

     The foregoing discussion and the discussions in the Prospectus applicable
to each shareholder address only some of the Federal tax considerations
generally affecting investments in the Funds.  Each investor is urged to consult
his or her tax Advisor regarding specific questions as to Federal, state, local
or foreign taxes.

                                 CAPITAL STOCK

     The Funds are four of the Funds of the Wells Fargo Funds Trust family of
funds. The Trust was organized as a Delaware business trust on March 10, 1999.

                                       38
<PAGE>

     Most of  the Trust's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors.  Certain of the Trust's funds also are authorized to issue
other classes of shares, which are sold primarily to institutional investors.
Each class of shares in a fund represents an equal, proportionate interest in a
fund with other shares of the same class.  Shareholders of each class bear their
pro rata portion of the fund's operating expenses, except for certain class-
specific expenses (e.g., any state securities registration fees, shareholder
servicing fees or distribution fees that may be paid under Rule 12b-1) that are
allocated to a particular class.  Please contact Investor Services at 1-800-222-
8222 if you would like additional information about other funds or classes of
shares offered.

     With respect to matters that affect one class but not another, shareholders
vote as a class; for example, the approval of a Plan.  Subject to the foregoing,
all shares of a Fund have equal voting rights and will be voted in the
aggregate, and not by Series, except where voting by a Series is required by law
or where the matter involved only affects one Series.  For example, a change in
a Funds' fundamental investment policy affects only one Series and would be
voted upon only by shareholders of the Fund involved.  Additionally, approval of
an Advisory contract, since it only affects one Fund, is a matter to be
determined separately by each Series.  Approval by the shareholders of one
Series is effective as to that Series whether or not sufficient votes are
received from the shareholders of the other series to approve the proposal as to
those Series.

     As used in the Prospectus and in this SAI, the term "majority" when
referring to approvals to be obtained from shareholders of a Class of the Fund,
means the vote of the lesser of (i) 67% of the shares of such class the Fund
represented at a meeting if the holders of more than 50% of the outstanding
shares such class of the Fund are present in person or by proxy, or (ii) more
than 50% of the outstanding shares of such class the Fund.  The term "majority,"
when referring to the approvals to be obtained from shareholders of the Trust as
a whole, means the vote of the lesser of (i) 67% of the Trust's shares
represented at a meeting if the holders of more than 50% of the Trust's
outstanding shares are present in person or by proxy, or (ii) more than 50% of
the Trust's outstanding shares.  Shareholders are entitled to one vote for each
full share held and fractional votes for fractional shares held.

     Shareholders are not entitled to any preemptive rights.  All shares, when
issued for the consideration described in the Prospectus, will be fully paid and
non-assessable by the Trust.  The Trust may dispense with an annual meeting of
shareholders in any year in which it is not required to elect directors under
the 1940 Act.

     Each share of a class of a Fund represents an equal proportional interest
in a Fund with each other share in the same class and is entitled to such
dividends and distributions out of the income earned on the assets belonging to
a Fund as are declared in the discretion of the Trustees.  In the event of the
liquidation or dissolution of the Trust, shareholders of a Fund are entitled to
receive the assets attributable to the relevant class of shares of the Fund that
are available for distribution, and a distribution of any general assets not
attributable to a particular investment portfolio that are available for
distribution in such manner and on such basis as the Trustees in their sole
discretion may determine.

     Set forth below as of May 25, 1999 is the name, address and share ownership
of each person known by the Trust to have beneficial or record ownership of 5%
or more of a class of a Fund or 5% or more of the voting securities of the Fund
as a whole.  The term "N/A" is used where a shareholder holds 5% or more of a
class, but less than 5% of a Fund as a whole.

                                   APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate bonds and commercial paper.

Corporate Bonds
- ---------------

     Moody's:  The four highest ratings for corporate bonds are "Aaa," "Aa," "A"
     -------
and "Baa."  Bonds rated "Aaa" are judged to be of the "best quality" and carry
the smallest amount of investment risk.  Bonds rated "Aa" are of "high quality
by all standards," but margins of protection or other elements make long-term
risks appear somewhat greater than "Aaa" rated bonds.  Bonds rated "A" possess
many favorable investment attributes and are considered to be upper medium grade
obligations.  Bonds rated "Baa" are considered to be medium grade obligations;
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 have speculative
characteristics as well.  Moody's applies numerical modifiers:  1, 2 and 3 in
each rating category from "Aa" through "Baa" in its rating system.  The modifier
1 indicates that the security ranks in the higher end of its category; the
modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the
issue ranks in the lower end.

     S&P:  The four highest ratings for corporate bonds are "AAA," "AA," "A" and
     ---
"BBB."  Bonds rated "AAA" have the highest ratings assigned by S&P and have an
extremely strong capacity to pay interest and repay principal.  Bonds rated "AA"
have a "very strong capacity to pay interest and repay principal" and differ
"from the highest rated issued only in small degree."  Bonds rated "A" have a
"strong capacity" to pay interest and repay principal, but are "somewhat more
susceptible" to adverse effects of changes in economic conditions or other
circumstances than bonds in higher rated categories.  Bonds rated "BBB" are
regarded as having an "adequate capacity" to pay interest and repay principal,
but changes in economic conditions or other circumstances are more likely to
lead to a "weakened capacity" to make such repayments.  The ratings from "AA" to
"BBB" may be modified by the addition of a plus or minus sign to show relative
standing within the category.

Corporate Commercial Paper
- --------------------------

     Moody's:  The highest rating for corporate commercial paper is "P-1"
     -------
(Prime-1).  Issuers rated "P-1" have a "superior capacity for repayment of
short-term promissory obligations."  Issuers rated "P-2" (Prime-2) "have a
strong capacity for repayment of short-term promissory obligations," but
earnings trends, while sound, will be subject to more variation.

     S&P:  The "A-1" rating for corporate commercial paper indicates that the
     ---
"degree of safety regarding timely payment is either overwhelming or very
strong."  Commercial paper with "overwhelming safety characteristics" will be
rated "A-1+."  Commercial paper with a strong capacity for timely payments on
issues will be rated "A-2."

                                      A-1

                WELLS FARGO FUNDS TRUST BALANCED FUNDS OVERVIEW

Growth Balanced Fund

Objective
Seeks to provide a combination of current income and capital appreciation by
diversifying investments in stocks and bonds.

Principal Strategy
We divide the Fund's investments between fixed income securities and equity
securities in varying proportions, with an emphasis on equity securities.

Index Allocation Fund

Objective
Seeks to earn to earn a high level of total return, consistent with the
assumption of reasonable risk.

Principal Strategy
We allocate and reallocate assets among common stocks, U.S. Treasury Bonds and
money market instruments.  We invest in asset classes that we believe are
undervalued in order to achieve better long-term, risk-adjusted returns.

LifePath Funds

Objective
Each LifePath Fund seeks to maximize assets available for retirement or other
purposes, consistent with the quantitatively measured risk that investors, on
average, may be willing to accept given their investment time horizon.  The
Funds with shorter time horizons (LifePath Opportunity and LifePath 2010, for
instance) will tend to be less risky and have lower expected returns than the
Fund with longer time horizons (LifePath 2030 and LifePath 2040).  Investors are
encouraged to select a particular LifePath Fund based on their investment time
horizon.  Specifically,

 .    LifePath Opportunity Fund is managed for investors who have retired or who
     are planning to retire (or begin to withdraw substantial portions of their
     investment) approximately in the year 2000.

     The Fund also may be appropriate for investors with a shorter time horizon.
     The Fund does not terminate in the Year 2000, but will continue with the
     lowest risk profile of all the LifePath Funds. It is expected that when the
     LifePath 2010 Fund's target date arrives, the LifePath 2010 Fund will be
     combined with the LifePath Opportunity Fund under the same investment
     strategy. The LifePath Opportunity Fund will continue to follow an asset
     allocation strategy that will invest approximately 20% equity securities,
     with the remainder in debt securities and cash.

 .    LifePath 2010 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2010.

 .    LifePath 2020 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2020.

 .    LifePath 2030 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2030.

 .    LifePath 2040 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2040.

                                       4
<PAGE>

Principal Strategy
We allocate and reallocate assets of each LifePath Fund among a wide range of
U.S. and international common stocks, fixed-income securities and money market
instruments according to the recommended mix suitable for each Fund's risk
level.

Summary Of Important Risks

 This section summarizes important risks that are common to all of the Funds
 described in this Prospectus, and important risks that relate specifically to
 particular Funds.  Both are important to your investment choice.  Additional
 information about these and other risks is included in the individual Fund
 Descriptions later in this Prospectus, under General Investment Risks beginning
 on page __ and in the Funds' Statement of Additional Information.  An
 investment in a Fund is not a deposit of Wells Fargo Bank and is not insured or
 guaranteed by the Federal Deposit Insurance Corporation or any other government
 agency.

 Common Risks for the Funds

 Equity Securities.  Each Fund invests in equity securities, which are subject
 to equity market risk.  This is the risk that stock prices will fluctuate and
 can decline and reduce the value of a Fund's portfolio.  Certain types of stock
 and certain individual stocks selected for a Fund's portfolio may underperform
 or decline in value more than the overall market.  As of the date of this
 Prospectus, the equity markets, as measured by the S&P 500 Index and other
 commonly used indexes, are trading at or close to record levels.  There can be
 no guarantee that these levels will continue.  The Funds that invest in smaller
 companies, in foreign companies (including investments made through American
 Depositary Receipts and similar instruments), and in emerging markets are
 subject to additional risks, including less liquidity and greater price
 volatility.  A Fund's investment in foreign companies and emerging markets are
 also subject to special risks associated with international investing,
 including currency, political, regulatory and diplomatic risks.

 Debt Securities.  The Funds may invest some of their assets in debt securities,
 such as notes and bonds, which are subject to credit risk and interest rate
 risk.  Credit risk is the possibility that an issuer of an instrument will be
 unable to make interest payments or repay principal.  Changes in the financial
 strength of an issuer or changes in the credit rating of a security may affect
 its value.  Interest rate risk is the risk that interest rates may increase,
 which will reduce the resale value of instruments in a Fund's portfolio,
 including U.S. Government obligations.  Debt securities with longer maturities
 are generally more sensitive to interest rate changes than those with shorter
 maturities.  Changes in market interest rates do not affect the rate payable on
 debt instruments held in a Fund, unless the instrument has adjustable or
 variable rate features, which can reduce interest rate risk.  Changes in market
 interest rates may also extend or shorten the duration of certain types of
 instruments, such as asset-backed securities, thereby affecting their value and
 the return on your investment.

Growth Balanced Fund                   This Fund invests in smaller companies
                                       that may be more volatile than
                                       investments in larger companies. Smaller
                                       companies also may have higher failure
                                       rate than larger companies. The Fund also
                                       is subject to leverage risk, which is the
                                       risk that some small transactions may
                                       multiply smaller market movements into
                                       large changes in the Fund's net asset
                                       value. This risk may occur when the Fund
                                       borrows money or enters into transactions
                                       that have a similar effect, such as short
                                       sales and forward commitment
                                       transactions. This risk also may occur
                                       when the Fund makes investment in
                                       derivatives, such as options or futures
                                       contracts.

- --------------------------------------------------------------------------------
LifePath Opportunity Fund              These Funds may incur a higher than
LifePath 2010 Fund                     average portfolio turnover ratio due to
LifePath 2020 Fund                     allocation shifts recommended by each
LifePath 2030 Fund                     Fund's investment model. Foreign
LifePath 2040 Fund                     obligations may entail additional risks.
                                       Investments in options on stock indexes
                                       depend on movements in the market in
                                       general, or price level movements for a
                                       particular index, rather than price
                                       movements for an individual issue.

                                       seeks undervalued asset classes. There is
                                       no guarantee that the model will make
                                       accurate determinations or that an asset
                                       class we believe is undervalued will
                                       perform as expected.

Growth Balanced Fund

Investment Objective
The Growth Balanced Fund seeks to provide a combination of current income and
capital appreciation by diversified investments in stocks and bonds.

Investment Policies
We divide the Fund's investments between fixed income securities and equity
securities in verifying proportions, with an emphasis on equity securities.  The
Fund is designed for investors seeking long-term capital appreciation in the
equity securities market in a balanced fund.  The Fund currently invests in [14]
core portfolios of Wells Fargo Core Trusts.

Permitted Investments
The Fund invests the equity portion of its portfolio in the [5] different equity
investment core portfolios.  The blending of multiple equity investment styles
is intended to reduce the risk associated with the use of a single style, which
may move in and out of favor during the course of a market cycle.  The Fund
invests the fixed-income portion of its portfolio in [Positive Return Bond
Portfolio, Strategic Value Bond Portfolio, and Managed Fixed Income Portfolio.]
The blending of multiple fixed-income investment styles is intended to reduce
the price and return volatility of, and provide more consistent returns within,
the fixed-income portion of the Fund's investments.

The percentage of the Fund's assets invested in different core portfolios may
temporarily deviate from the Fund's current allocation due to changes in market
values.  The investment advisor will effect transactions periodically to re-
establish the current allocation.

As market or other conditions change, the advisor may attempt to enhance the
Fund's returns by changing the percentage of Fund assets invested in fixed-
income and equity securities.  The Fund also may invest in more or fewer
Portfolios or invest directly in portfolio securities.  Absent unstable market
conditions, the Advisor does not anticipate making a substantial number of
percentage changes.  When the Advisor believes that a change in the current
allocation percentages is desirable, it will sell and purchase securities to
effect the change.  When the Advisor believes that a change will be temporary
(generally, three years or less), it may effect the change by using futures
contracts.

Important Risk Factors
Investments in the Fund will be subject both to the risks of fixed income
securities and the risks of equity securities discussed in the Summary of
Important Risks on page __.  You should also consider the General Investment
Risks beginning on page __.  They are all important to your investment choice.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure.  In this structure,
the "gateway" Growth Balanced Fund invests all of its assets in various "core"
portfolios whose objectives and investment policies are consistent with the
Fund's investment objective.  Gateway funds investing in various core portfolios
can enhance their investment opportunities and reduce their expenses through
sharing the costs of managing a large pool of assets.  References to the
investment activities of the Fund also refer to the investments of the core
portfolios in which it invests.

Index Allocation Fund

Investment Objective
The Index Allocation Fund seeks to earn a high level of total return, consistent
with the assumption of reasonable risk.

Investment Policies
We allocate and reallocate assets among common stocks, U.S. Treasury bonds and
money market instruments.  This strategy is based on the premise that asset
classes are at times undervalued or overvalued in comparison to one another and
that investing in undervalued asset classes offers better long-term, risk-
adjusted returns.

Permitted Investments
We invest in the following asset classes:

 .    Stock Investments--We invest in common stocks representative of the S&P 500
     Index. We do not individually select common stock on the basis of
     traditional investment analysis. Instead stock investments are made
     according to a weighted formula intend to match the of the S&P 500 Index as
     closely as possible.

 .    Bond Investments--We invest in U.S. Treasury bonds representative of the
     Lehman Brothers 20+ Bond Index. Bonds on this Index will have maturities of
     20 years or more; and

 .    Money Market Investments--We invest this portion of the Fund in high-
     quality money market instruments, including U.S. Government obligations,
     obligations of foreign and domestic banks, short-term corporate debt
     instruments and repurchase agreements.

In addition, under normal market conditions, we invest:

 .    at least 65% of assets in stocks representative of the S&P 500 Index, the
     Lehman Brothers 20+ Bond Index or a combination of both;

 .    in call and put options on stock indexes, stock index futures, options on
     stock index futures, interest rate and Interest Rate Futures contracts as a
     substitute for a comparable market position in stocks;

 .    in interest rate and Index Swaps; and

 .    up to 25% of total assets in obligations of foreign banks qualifying as
     money market investments.

We manage the allocation of investments in the Fund's portfolio based on the
assumption that the Fund's "normal" allocation is 100% stocks and no bonds.
This is not a "target" allocation but rather a measure of the level of risk
tolerance for the Fund.

We are not required to keep a minimum investment in any of the three asset
classes, nor are we prohibited from investing substantially all of our assets in
a single class.  The asset allocation may shift as any time.  In addition, we
may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, repurchase agreements and other short-term
investments, to maintain liquidity or when we believe it is in the best interest
of shareholders to do so.

Important Risk Factors
There is no guarantee that securities selected as "undervalued" will perform as
expected.  Stocks of smaller, medium-sized and foreign companies purchased using
the value approach may be more volatile and less liquid than other comparable
securities.

You should consider the Summary of Important Risks on page [__], the General
Investment Risks beginning on page [__], and the specific risks listed above.
They are all important to your investment choice.

Additional Fund Facts
Barclays Global Fund Advisors, as the sub-advisor, uses a proprietary investment
model that analyzes extensive financial data from numerous sources and
recommends a portfolio allocation for the Fund.  The model incorporates
assumptions for expected risks and returns and investor attitudes for risk.  The
model is run daily and recommendations are made in 5% increments.  No person is
primarily responsible for recommending either the asset mix or the mix of
securities within a class.  The Fund is not designed to profit from short-term
market changes.  Instead, it is designed for investors with investment horizons
of three to five years.  We allocate investments among the asset classes
described above.  The Fund does not attempt to replicate the performance of a
single index and is not an index fund.

LifePath Funds

Investment Objective
Each LifePath Fund seeks to maximize assets available for retirement or for
other purposes consistent with the quantitatively measured risk that investors,
on average, may be willing to accept given their investment time horizons.

Investors are encouraged to select a particular LifePath Fund based on their
investment time horizon.  Specifically,

 .    LifePath Opportunity Fund is managed for investors who have retired or who
     are planning to retire (or begin to withdraw substantial portions of their
     investment) approximately in the year 2000.

     The Fund also may be appropriate for investors with a shorter time horizon.
     The Fund does not terminate in the Year 2000, but will continue with the
     lowest risk profile of all the LifePath Funds. It is expected that when the
     LifePath 2010 Fund's target date arrives, the LifePath 2010 Fund will be
     combined with the LifePath Opportunity Fund under the same investment
     strategy. The LifePath Opportunity Fund will continue to follow an asset
     allocation strategy that will invest approximately 20% equity securities,
     with the remainder in debt securities and cash.

 .    LifePath 2010 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2010.

 .    LifePath 2020 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2020.

 .    LifePath 2030 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2030.

 .    LifePath 2040 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2040.

Investment Policies
Each LifePath Fund holds stocks, bonds and short-term money market instruments
in proportions suggested by its own comprehensive strategy.  The strategies go
further, allocating assets among indexes and sub-categories within various
investment classes.  Some of the sub-categories are well-known broad-based
market indexes, such as the S&P 500 Index of large-company stocks, and others
were specifically created to reflect a particular market segment.  This broad
diversification is designed to produce the highest expected returns for a given
level of risk.

The LifePath Funds were the first Funds of their kind to offer a flexible
investment strategy designed to change over specific time horizons.  Typically,
long-term investment goals are pursued with a more aggressive mix of equities
and fixed-income securities than short-term goals.  The allocation of each Fund
gradually grows more conservative as the year in the Fund's title approaches.
You are encouraged to choose the LifePath Fund whose title year most closely
matches the year during which you expect to begin regularly redeeming shares.
Keep in mind, however, that the year in each Fund's title also serves as a guide
to the relative aggressiveness of each Fund, where the LifePath 2040 Fund has
the most aggressive asset allocation and the LifePath Opportunity Fund has the
least aggressive asset allocation.  If you have a low risk tolerance, you may
not wish to invest in the Life Path 2040 Fund, for example, even if you do not
expect to retire for another forty years.  Conversely, you may feel comfortable
choosing a more aggressive LifePath Fund for a near-term investment goal.

We allocate and reallocate assets among a wide range of U.S. and international
common stocks, fixed-income securities and money market instruments according to
the recommended mix suitable for each Fund's risk level.  Under normal
conditions, the LifePath Opportunity Fund will typically invest 80% of its
assets in fixed-income classes and up to 20% in equities as it seeks stable
income production and reduced

                                       14
<PAGE>

volatility. The more aggressive Funds may invest in up to 100% stocks, but as
their title year approaches, their allocation will increasingly resemble the
current allocation of the LifePath Opportunity Fund.

The LifePath Opportunity Fund will not terminate when it reaches the year 2000.
Instead, the Fund will enter its "post target" strategy during which it will
seek to maximize total return consistent with assuming the lowest risk of any
LifePath series.  The Fund will continue to follow an asset allocation strategy
among three broad investment classes:  equity and debt securities of domestic
and foreign issuers and cash in the form of money market instruments.  However,
unlike the remaining LifePath Funds with target dates, during its post target
strategy the LifePath Opportunity Fund will no longer reduce its investment risk
through time.  Instead, the Fund is expected to have a long-term average mix of
approximately 20% equity securities, with the remainder in debt securities and
cash.  In the same manner as all LifePath Funds, the LifePath Opportunity Fund
will continue to employ a tactical asset allocation component, which will alter
the investment mix to account for changing expected risks and opportunities.
When other LifePath Funds reach their target date, it is expected that
shareholders will be asked to approve combining such Funds with the LifePath
Opportunity Fund.

Asset Allocation Decisions
In buying securities for each Fund, Barclays Global Fund Advisors ("BGFA"), the
Funds' investment advisor, does not select individual companies.  Instead, BGFA
focuses on selecting a mix of indexes by measuring their risk level and expected
returns based on a proprietary set of criteria.  The Funds then allocate a
portion of their assets to each index appropriate for each individual Fund.
Where possible, the Funds buy all the securities that comprise the index.  If
the index includes too many securities to buy them all, the Funds buy a
representative sample.  The Funds seek to match the index's return as closely as
possible.  The Funds focus on the selection of indexes or asset classes and do
not try to avoid individual under-performing securities investments nor do they
try to pick individual investments that might outperform the index.

This strategy stems from the belief that asset allocation decisions -- which
index or investment category you choose -- matter more to overall investment
performance than individual security selection -- which stock or bond you
choose.

Risk Tolerance
Two general rules of investing have shaped the Funds' strategies:

 .    Higher investment returns usually go hand-in-hand with higher risk; put
     another way, the greater its potential for loss. Historically, for example,
     stocks have out performed bonds, but the worst year for stocks on record
     was much worse than the worst year for bonds.

 .    The longer an investors' time horizon, the greater their risk tolerance;
     their investments have more time to recoup their losses.

The LifePath Funds with longer time horizons take more risks.  This normally
gives investors the potential for greater returns than the Funds with shorter
time horizons.  As a Fund approaches its time horizon, and its investors have
less time to recover from market declines, the Fund systematically reduce the
level of risk.  This systematic shift toward more stable investments should help
secure the value of your LifePath investment as the time nears for you to begin
drawing on it.

BGFA does not limit the analysis to long-term expectations.  The Funds also take
into account short-term market conditions.  If conditions in a market have
increased risk levels of an investment type or index to a point that its risk
outweighs its expected returns, the Funds will not allocate as much of their
assets to it as it otherwise might.  Conversely, the Funds may reduce their
allocation, even when risks have not increased, because its expected return has
fallen.  This usually happens because prices in a market have risen so high that
the potential for further gains appears limited.

Model-Driven Decisions
The Fund's assets are allocated across investment groups according to a
sophisticated mathematical model that was developed in 1993 and is continually
refined.  BGFA's investment professionals conduct ongoing research to enhance
the model and to ensure it is keeping pace with the world's constantly changing

                                       15
<PAGE>

financial markets.  Using this model, BGFA gains a consistent and objective
structure for making investment decisions.  Unlike traditional investment funds
that employ individual portfolio managers who make decisions on a more
subjective basis, BGFA applies a scientific approach to investing through the
use of such models.

After a Fund Reaches its Time Horizon
By the time a Fund reaches the decade identified by its name, it has reached its
least aggressive state in terms of building capital.  This does not mean that it
invests exclusively in money market instruments.  Rather, because BGFA believes
that most investors are still willing to take some risks in pursuing returns
even while drawing on their investments, the Fund continues to allocate a
portion of its assets to stocks and bonds, in addition to money market
instruments.  On average, BGFA expects that about 20% of the Fund's assets will
be invested in stocks, with the rest in bonds and money market instruments.

Permitted Investments
We do not select individual securities based on traditional investment analysis.
Instead, we allocate investments across as many as 17 asset classes, as
represented by the indexes listed below and money market instruments.

We use a statistical method known as "sampling" in order to try to recreate the
total return of the following stock indexes as closely as possible:

 .    The S&P/BARRA Value Stock Index, which consists primarily of large-
     capitalization of U.S. stocks with lower than average price-to-book ratios;

 .    The S&P/BARA Growth Stock Index, which consists primarily of large-
     capitalization U.S. stocks with higher than average price-to-book ratios;

 .    The Intermediate Capitalization Value Index, which consists primarily of
     medium-capitalization U.S. stocks with lower than average price-to-book
     ratios;

 .    The Intermediate Capitalization Growth Index, which consists primarily of
     medium-capitalization U.S. stocks with higher than average price-to-book
     ratios;

 .    The Intermediate Capitalization Utility Stock Index, which consists
     primarily of medium-capitalization U.S. utility stocks;

 .    The Micro Capitalization Market Index, which consists primarily of small-
     capitalization U.S. stocks;

 .    The Small Capitalization Growth Stock Index, which consists primarily of
     small-capitalization U.S. stocks with lower than average price-to-book
     ratios;

 .    The Small Capitalization Growth Stock Index, which consists primarily of
     small-capitalization U.S. stocks with higher than average price-to-book
     ratios;

 .    The Morgan Stanley Capital International Japan Index, consisting primarily
     of large-capitalization Japanese stocks; and

 .    The Morgan Stanley Capital International Europe, Australia, Far East ex-
     Japan Index, consisting primarily of non-Japanese foreign stocks.

We seek exposure to the U.S. fixed-income markets by investing in securities
representative of the following indexes:

 .    The Lehman Brothers Long-Term Government Bond Index, which consists of all
     U.S. Government bonds with maturities of at least ten years;

 .    The Lehman Brothers Intermediate-Government Bond Index, which consists of
     all U.S. Government bonds with maturities of less than ten years but more
     than one year;

 .    The Lehman Brothers Long-Term Corporate Bond Index, which consists of all
     investment-grade U.S. corporate bonds with maturities of at least ten
     years;

 .    The Lehman Brothers Intermediate-Term Corporate Bond Index, which consists
     of all investment-grade U.S. corporate bonds with maturities of less than
     ten years but more than one year;

 .    The Lehman Brothers Mortgage-Backed Securities Index, which consists of all
     fixed-coupon mortgage pass-throughs issued by or backed by the U.S.
     Government or its agencies.

                                       16
<PAGE>

We seek foreign debt market exposure through investment in securities
representative of the Solomon Brothers Non-U.S. World Government Bond Index,
which consists of a range of foreign government bonds with maturities of greater
than one year.

We also invest in high-quality money market instruments, including U.S.
Government obligations, obligations of foreign and domestic banks, short-term
corporate debt instruments and repurchase agreements.

We may also invest in stocks of U.S. and foreign issuers not included in the
indexes listed above.  Foreign equity exposure may be through stocks purchased
on foreign exchanges or through American Depository Receipts or similar
instruments sold on U.S. exchanges.

In addition, under normal market conditions, we may invest:

 .    in call and put options on stock indexes, stock index futures, options on
     stock index futures, interest rate and interest rate futures contracts as a
     substitute for a comparable market position in stocks; and

 .    in interest rate and index swaps.

We are not required to keep a minimum investment in any of the asset classes,
nor are we prohibited from investing substantially all of our assets in a single
class.  The allocation may shift at any time.  As part of our investment
strategy, we may invest varying portions of our assets in money market
instruments.  In addition, we may temporarily hold assets in cash or in money
market instruments, including U.S. Government obligations, repurchase agreements
and other short-term investments, to maintain liquidity or when we believe it is
in the best interest of shareholders to do so.  Each Fund is a diversified
portfolio.

Important Risk Factors
We may incur a higher than average portfolio turnover ratio due to allocation
shifts recommended by the investment model.  Foreign obligations may entail
additional risks.  The value of investments in options on stock indexes is
affected by price level movements for a particular index, rather than price
movements for an individual issue.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

Additional Fund Facts
The allocations across asset classes are recommended by a proprietary investment
model that analyzes extensive financial and economic data, including relative
risk and return statistics.  We have broad latitude in allocating the Fund's
investments and in refining the model.  No person is primarily responsible for
recommending either the asset mix or the mix of securities within a class.  We
may invest in fewer asset classes than listed above, particularly for any Fund
with less than $150 million in total assets.

Master Feeder Structure
Each LifePath Fund invests all of its assets in a corresponding Master Portfolio
of Master Investment Portfolio that have substantially similar investment
objectives as the Fund.  BGFA serves as Advisor to each Master Portfolio.  The
Master Portfolios may accept investments from other feeder funds.

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds.  Certain common risks are identified in the
Summary of Important Risks on page ___.  Other risks of mutual fund investing
include the following:

 .    Unlike bank deposits, such as CDs or savings accounts, mutual funds are not
     insured by the FDIC.

 .    We cannot guarantee that we will meet our investment objectives.

 .    We do not guarantee the performance of a Fund, nor can we assure you that
     the market value of your investment will not decline. We will not "make
     good" any investment loss you may suffer, nor can anyone we contract with
     to provide certain services, such as selling agents or investment advisors,
     offer or promise to make good any such losses.

 .    Share prices -- and therefore the value of your investment -- will increase
     and decrease with changes in the value of the underlying securities and
     other investments. This is referred to as price volatility.

 .    Investing in any mutual fund, including those deemed conservative, involves
     risk, including the possible loss of any money you invest.

 .    An investment in a single Fund, by itself, does not constitute a complete
     investment plan.

 .    The Funds that invest in smaller companies, foreign companies (including
     investments made through American Depositary Receipts and similar
     instruments), and in emerging markets are subject to additional risks,
     including less liquidity and greater price volatility. A Fund's investment
     in foreign and emerging markets may also be subject to special risks
     associated with international trade, including currency, political,
     regulatory and diplomatic risk.

 .    The Funds may invest a portion of their assets in U.S. Government
     obligations. It is important to recognize that the U.S. Government does not
     guarantee the market value or current yield of those obligations. Not all
     U.S. Government obligations are backed by the full faith and credit of the
     U.S. Treasury, and the U.S. Government's guarantee does not extend to the
     Funds themselves.

 .    The Funds may also use certain derivative instruments, such as options or
     futures contracts. The term "derivatives" covers a wide number of
     investments, but in general it refers to any financial instrument whose
     value is derived, at least in part, from the price of another security or a
     specified index, asset or rate. Some derivatives may be more sensitive to
     interest rate changes or market moves, and some may be susceptible to
     changes in yields or values due to their structure or contract terms.

 .    The Funds may temporarily hold assets in cash or in money market
     instruments, including U.S. Government obligations, shares of other mutual
     funds and repurchase agreements, or make other short-term investments,
     either to maintain liquidity or for short-term defensive purposes when we
     believe it is in the best interests of shareholders to do so. Except with
     respect to money market Funds, to the extent a Fund's assets are so
     invested, they may cause a Fund to not achieve its investment objective.
     This practice is expected to have limited, if any, effect on the Funds'
     pursuit of their objectives over the long term.

 .    The Funds may invest a portion of their assets in U.S. Government
     obligations, such as securities issued or guaranteed by the Government
     National Mortgage Association ("GNMAs"), the Federal National Mortgage
     Association ("FNMAs") and the Federal Home Loan Mortgage Corporation
     ("FHLMCs"). Each are mortgage-backed securities representing partial
     ownership of a pool of residential mortgage loans. A "pool" or group of
     such mortgages is assembled and, after being approved by the issuing or
     guaranteeing entity, is offered to investors through securities dealers.
     Mortgage-backed securities are subject to prepayment and extension risk,
     which can alter the maturity of the securities and also reduce the rate of
     return on the portfolio. Collateralized mortgage obligations ("CMOs")
     typically represent principal-only and interest-only portions of such
     securities and are subject to increased interest-rate and credit risk.

                                       18

General Investment Risks (Cont'd)

 .    The market value of lower-rated debt securities and unrated securities of
     comparable quality that the Funds may invest in tends to reflect individual
     developments affecting the issuer to a greater extent than the market value
     of higher-rated securities, which react primarily to fluctuations in the
     general level of interest rates. Lower-rated securities also tend to be
     more sensitive to economic conditions than higher-rated securities. These
     lower-rated debt securities are considered by the rating agencies, on
     balance, to be predominantly speculative with respect to the issuer's
     capacity to pay interest and repay principal. These securities generally
     involve more credit risk than securities in higher-rating categories. Even
     securities rated "BBB" by S&P or by Moody's ratings which are considered
     investment-grade, possess some speculative characteristics.

Investment practices and risk levels are carefully monitored.  Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Fund and a table showing some of the
additional investment practices that each Fund may use and the risks associated
with them.  Additional information about these practices is available in the
Statement of Additional Information.

Counter-Party Risk -- The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

Credit Risk -- The risk that the issuer of a debt security will be unable to
make interest payments or repay principal on schedule.  If an issuer does
default, the affected security could lose all of its value, or be renegotiated
at a lower interest rate or principal amount.  Affected securities might also
lose liquidity.  Credit risk also includes the risk that a party in a
transaction may not be able to complete the transaction as agreed.

Currency Risk-- The risk that a change in the exchange rate between U.S. dollars
and a foreign currency may reduce the value of an investment made in a security
denominated in that foreign currency.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value of
liquidity of investments in either country.

Emerging Market Risk--The risk that the emerging market, as defined in the
glossary, may be more sensitive to certain economic changes.  For example,
emerging market countries are often dependent on international trade and are
therefore often vulnerable to recessions in other countries.  They may have
obsolete financial systems, have volatile currencies and may be more sensitive
than more mature markets to a variety of economic factors.  Emerging market
securities may also be less liquid than securities of more developed countries
and could be difficult to sell, particularly during a market downturn.

Experience Risk--The risk presented by a new or innovative security.  The risk
is that insufficient experience exists to forecast how the security's value
might be affected by various economic conditions:

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security.  Generally, when interest rates increase, the value of
a debt security decreases.  The effect is usually more pronounced for securities
with longer dates to maturity.

                                       19
<PAGE>

General Investment Risks (Cont'd)

Leverage Risk--The risk that an investment practice such as lending portfolio
securities or engaging in forward commitments or when-issue securities
transactions may increase a Fund's exposure to market risk, interest rate risk
or other risks by, in effect, increasing assets available for investment.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of a stock, bond or other security will be
reduced by market activity. This is a basic risk associated with all securities.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

Prepayment Risk--The risk that consumers will accelerate their prepayment of
mortgage loans or other receivables, which can shorten the maturity of a
mortgage-backed or other asset-backed security and reduce a portfolio's rate of
return.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security. Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Year 2000 Risk--The Funds' principal service providers have advised the Funds
that they are working on the necessary changes to their computer systems to
avoid any system failure based on an inability to distinguish the year 2000 from
the year 1900, and that they expect their systems to be adapted in time. There
can, of course, be no assurance of success. In addition, the companies or
entities in which the Funds invest also could be adversely impacted by the Year
2000 issue, especially foreign entities, which may be less prepared for Year
2000. The extent of such impact cannot be predicted.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund. You should also
see the Statement of Additional Information for additional information about the
investment practices and risks particular to each Fund.

Investment Practice/Risk

The following table lists some of the additional investment practices of the
Funds, including some not disclosed in the Investment Objective and Investment
Policies sections of the Prospectus. The risks indicated after the description
of the practice are NOT the only potential risks associated with that practice,
but are among the more prominent. Market risk is assumed for each. See the
Investment Objective and Investment Policies for each Fund or the Statement of
Additional Information for more information on these practices.

Organization and Management of the Funds

A number of different entities provide services to the Funds. This section shows
how the Funds are organized, lists the entities that perform different services,
and explains how these service providers are compensated. Further information is
available in the Statement of Additional Information for the Funds.

About Wells Fargo Funds Trust
Each Fund is one of over 60 Funds of Wells Fargo Funds Trust (the "Trust"), an
open-end management investment company. The Trust was organized as a Delaware
business trust on March 10, 1999. The Board of Trustees of the Trust supervises
each Fund's activities, monitors its contractual arrangements with various
service providers and decides upon matters of general policy.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds. The holding company of Wells Fargo Bank, the investment advisor to the
Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998. Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one Stagecoach or Norwest
Advantage Funds. The performance and financial statement history of each
predecessor Fund will be assumed by the Wells Fargo Funds Trust Fund. The
succession transactions are conditioned on shareholder approval by the
shareholders of the various Stagecoach and Norwest Advantage Funds. The Table on
page __ identifies the Stagecoach and Norwest predecessors to the Funds.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund class paid on an annual basis for the
services described.

A Choice of Share Classes
After choosing a Fund, your next most important choice is which share class to
buy. The following classes of shares are available through this Prospectus:
 .    Class A Shares - with a front-end sales charge, volume reductions and lower
     on-going expenses than Class B and Class C shares.
 .    Class B Shares - with a contingent deferred sales charge ("CDSC") payable
     upon redemption that diminishes over time, and higher on-going expenses
     than Class A shares.
 .    Class C Shares - with a 1.00% CDSC on redemptions made within one year of
     purchase, and higher on-going expenses than Class A shares.

The choice between share classes is largely a matter of preference. You should
consider, among other things, the different fees and sales loads assessed on
each share class and the length of time you anticipate holding your investment.
If you prefer to pay sales charges up front, wish to avoid higher on-going
expenses, or, more importantly, you think you may qualify for volume discounts
based on the amount of your investment, then Class A shares may be the choice
for you.

You may prefer to see "every dollar working" from the moment you invest. If so,
then consider Class B or Class C shares. Please note that Class B shares convert
to Class A shares after seven years to avoid the higher on-going expenses
assessed against Class B shares.

Class C shares are similar to Class B shares, with some important differences.
Unlike Class B shares, Class C shares do not convert to Class A shares. The
higher on-going expenses will be assessed as long as you hold the shares. The
choice between Class B and Class C shares may depend on how long you intend to
hold Fund shares before redeeming them.

Please see the expenses listed for each Fund and the following sales charge
schedules before making your decision. You should also review the "Reduced Sales
Charges" section of the Prospectus. You may wish to discuss this choice with
your financial consultant.

Class A Share Sales Charge Schedule
If you choose to buy Class A shares, you will pay the Public Offering Price
("POP") which is the Net Asset Value ("NAV") plus the applicable sales charge.
The money market funds listed in this prospectus do not impose sales charges on
the purchase of Class A shares. Since sales charges are reduced for Class A
share purchases above certain dollar amounts, known as "breakpoint levels", the
POP is lower for these purchases.

/1/We will assess a 1.00% CDSC on Class A shares purchases of $1,000,000 or more
or if they are redeemed within one year from the date of purchase. Charges are
based on the lower of the NAV on the date of purchase or the date of redemption.

Class B Share CDSC Schedule
If you choose Class B shares, you buy them at NAV and agree that if you redeem
your shares within six years of the purchase date, you will pay a CDSC based on
how long you have held your shares. Certain exceptions apply (see "Class B and
Class C Share CDSC Reductions" and "Waivers for Certain Parties"). The CDSC
schedule is as follows:

- --------------------------------------------------------------------------------------------------
</TABLE>

The CDSC percentage you pay is based on the lower of the NAV of the shares on
the date of the original purchase, or the NAV of the shares on the date of
redemption.

We always process partial redemptions so that the least expensive shares are
redeemed first in order to reduce your sales charges. After shares are held for
six years, the CDSC expires. After shares are held for seven years, the Class B
shares are converted to Class A shares to reduce your future on-going expenses.

Class B shares received in the reorganization of the Stagecoach Funds are
subject to the above CDSC schedule based on the purchase date(s) of the
Stagecoach shares, and such shares convert to Class A shares automatically after
six years.

Class B shares received in the reorganization of the Stagecoach Funds in
exchange for Stagecoach Fund shares that were purchased prior to March 3, 1997
are subject to a CDSC if they are redeemed within four years of the original
purchase. The CDSC Schedule for these shares is below:

The above-described schedules for shares of the former Stagecoach Funds and
Norwest Advantage Funds do not apply for any new shares purchased. If you
exchange the Class B shares received in the reorganization for Class B shares of
another Fund, you will retain these CDSC schedules on your exchanged shares.
Additional shares purchased will age at the higher CDSC schedule.

<PAGE>

Class C Share CDSC Schedule
If you choose Class C shares, you buy them at NAV and agree that if you redeem
your shares within one year of the purchase date, you will pay a CDSC of 1.00%.

The CDSC percentage you pay is based on the lower of the NAV on the date of the
original purchase, or the NAV on the date of redemption. The distributor pays
sales commissions of up to 1.00% of the purchase price of Class C shares to
selling agents at the time of the sale, and up to 1.00% annually thereafter.

We always process partial redemptions so that the least expensive shares are
redeemed first in order to reduce your sales charges. Class C shares do not
convert to Class A shares, and therefore continue to pay the higher on-going
expenses.

                                       29
<PAGE>

Reduced Sales Charges
Generally, we offer more sales charge reductions for Class A shares than for
Class B and Class C shares, particularly if you intend to invest greater
amounts. You should consider whether you are eligible for any of the potential
reductions when you are deciding which share class to buy.

Class A Share Reductions:

 .    You pay no sales charges on Fund shares you buy with reinvested
     distributions.
 .    You pay a lower sales charge if you are investing an amount over a
     breakpoint level. See the "Class A Share Sales Charge Schedule" above.
 .    By signing a Letter of Intent (LOI), you pay a lower sales charge now in
     exchange for promising to invest an amount over a specified breakpoint
     within the next 13 months. We will hold in escrow shares equal to
     approximately 5% of the amount you intend to buy. If you do not invest the
     amount specified in the LOI before the expiration date, we will redeem
     enough escrowed shares to pay the difference between the reduced sales load
     you paid and the sales load you should have paid. Otherwise, we will
     release the escrowed shares when you have invested the agreed amount.
 .    Rights of Accumulation (ROA) allow you to combine the amount you invest
     with the total NAV of shares you own in other Funds Trust front-end load
     Funds in order to reach breakpoint levels for a reduced load. We give you a
     discount on the entire amount of the investment that puts you over the
     breakpoint level.
 .    If you are reinvesting the proceeds of a Wells Fargo Funds redemption for
     shares on which you have already paid a front-end sales charge, you have
     [120 days] to reinvest the proceeds of that redemption with no sales charge
     into a Fund that charges the same or a lower front-end sales charge. If you
     use such a redemption to purchase shares of a Fund with a higher front-end
     sales charge, you will have to pay the difference between the lower and
     higher charge.
 .    You may reinvest into a Stagecoach Fund with no sales charge a required
     distribution from a pension, retirement, benefits, or similar plan for
     which Wells Fargo Bank acts as trustee provided the distribution occurred
     within the 30 days prior to your reinvestment.

If you believe you are eligible for any of these reductions, it is up to you to
ask the selling agent or the shareholder servicing agent for the reduction and
to provide appropriate proof of eligibility.

You, or your fiduciary or trustee, may also tell us to extend volume discounts,
including the reductions offered for rights of accumulation and letters of
intent, to include purchases made by:

 .    a family unit, consisting of a husband and wife and children under the age
     of twenty-one or single trust estate;
 .    a trustee or fiduciary purchasing for a single fiduciary relationship; or
 .    the members of a "qualified group" which consists of a "company" (as
     defined in the 1940 Act), and related parties of such a "Company," which
     has been in existence for at least six months and which has a primary
     purpose other than acquiring Fund shares at a discount.

How a Letter of Intent Can Save You Money!
If you plan to invest, for example, $100,000 in a Wells Fargo Fund in
installments over the next year, by signing a letter of intent you would pay
only 3.50% sales load on the entire purchase. Otherwise, you might pay 4.50% on
the first $50,000, then 4.00% on the next $49,999!

Class B and Class C Share CDSC Reductions:
 .    You pay no CDSC on Funds shares you purchase with reinvested distributions.
 .    We waive the CDSC for all redemptions made because of scheduled or
     mandatory distributions for certain retirement plans. (See your retirement
     plan disclosure for details.)

                                       30
<PAGE>

Reduced Sales Charges (Cont'd)

 .    We waive the CDSC for redemptions made in the event of the shareholder's
     death or for a disability suffered after purchasing shares. ("Disability"
     is defined by the Internal Revenue Code of 1986.)
 .    We waive the CDSC for redemptions made at the direction of Wells Fargo in
     order to, for example, complete a merger or close an account whose value
     has fallen below the minimum balance.
 .    We waive Class C share CDSC for certain types of accounts.

For Class B shares purchased [outside of an IRA] or other qualified plan after
May 18, 1999 for former Norwest Advantage Fund shareholders, after July 17, 1999
for former Stagecoach Funds shareholders, and after September 17, 1999 for all
other shareholders, no CDSC is imposed on withdrawals that occur under the
following circumstances:
 .    Withdrawals are made by participating in the Systematic Withdrawal Plan;
 .    Withdrawals may not exceed 10% of your fund assets annually based on your
     anniversary date in the Systematic Withdrawal Plan; and
 .    you must participate in the dividend and capital gain reinvestment program.

Waiver for Certain Parties
If you are eligible for certain waivers, we will sell you Class A shares so you
can avoid higher on-going expenses. The following people can buy Class A shares
at NAV:
 .    Current and retired employees, directors and officers of:
     .    Wells Fargo Funds and its affiliates;
     .    Wells Fargo Bank and their affiliates;
     .    Stephens and its affiliates; and
     .    Broker-Dealers who act as selling agents.
 .    [The spouses of any of the above, as well as the grandparents, parents,
     siblings, children, grandchildren, aunts, uncles, nieces, nephews, fathers-
     in-law, mothers-in-law, brothers-in-law and sisters-in-law of either the
     spouse or the current or retired employee, director of officer.]

You may also buy Class A Fund shares at NAV if they are to be included in
certain retirement, benefits, pension or investment "wrap accounts" with whom
Wells Fargo Funds has reached an agreement, or through an omnibus account
maintained with a Fund by a broker/dealer.

We reserve the right to enter into agreements that reduce or eliminate sales
charges for groups or classes of shareholders, or for Fund shares included in
other investment plans such as "wrap accounts." If you own Fund shares as part
of another account or package such as an IRA or a sweep account, you must read
the directions for that account. These directions may supersede the terms and
conditions discussed here.

Distribution Plan
We have adopted Distribution Plans pursuant to Rule 12b-1 for the Class A, Class
B and Class C shares of the Funds. The plans authorize the payment of all or
part of the cost of preparing and distributing prospectuses and distribution-
related services including ongoing compensation to selling agents. The Plan also
provides that, if and to the extent any shareholder servicing payments are
recharacterized as payments for distribution-related services, they are approved
and payable under the distribution plan. The fees paid under these plans are as
follows:

Reduced Sales Charges (Cont'd)

These fees are paid out of the Funds' assets on an on-going basis. Overtime,
these fees will increase the cost of your investment and may cost you more than
paying other types of sales charges.

Exchanges

Exchanges between Wells Fargo Funds are two transactions: a sale of shares of
one Fund and the purchase of shares of another. In general, the same rules and
procedures that apply to sales and purchases apply to exchanges. There are,
however, additional factors you should keep in mind while making or considering
an exchange:

 .    You should carefully read the Prospectus for the Fund into which you wish
     to exchange.
 .    Every exchange involves selling Fund shares and that sale may produce a
     capital gain or loss for federal income tax purposes.
 .    If you are making an initial investment into a new Fund through an
     exchange, you must exchange at least the minimum first purchase amount of
     the Fund you are redeeming, unless your balance has fallen below that
     amount due to market conditions.
 .    Any exchange between Funds you already own must meet the minimum redemption
     and subsequent purchase amounts for the Funds involved.
 .    Exchanges between Class B shares and the Wells Fargo Money Market Fund
     Class B shares will not trigger the CDSC. The new shares will continue to
     age according to their original schedule while in the new Fund and will be
     charged the CDSC applicable to the original shares upon redemption.
     Exchanges into Money Market Fund Class B shares are subject to certain
     restrictions in addition to those described above.
 .    Exchanges from any share class to a money market fund can only be re-
     exchanged for the original share class.
 .    In order to discourage excessive Fund transaction expenses that must be
     borne by other shareholders, we reserve the right to limit or reject
     exchange orders. Generally, we will notify you 60 days in advance of any
     changes in your exchange privileges.
 .    You may make exchanges between like share classes. You may also exchange
     from Class A or Class C shares to any non-institutional money market fund.

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:
 .    As with all mutual fund investments, the price you pay to purchase shares
     or the price you receive when you redeem shares is not determined until
     after a request has been received in proper form.
 .    We determine the Net Asset Value ("NAV") of each class of the Funds' shares
     each business day as of the close of regular trading on the NYSE. We
     determine the NAV by subtracting the Fund class's liabilities from its
     total assets, and then dividing the result by the total number of
     outstanding shares of that class. Each Fund's assets are generally valued
     at current market prices. See the Statement of Additional Information for
     further disclosure.
 .    We process requests to buy or sell shares of the funds each business day as
     of the close of regular trading on the New York Stock Exchange ("NYSE"),
     which is usually 1:00 p.m. (Pacific time)/3:00 p.m. (Central time). If the
     markets close early, the Funds may close early and may value their shares
     at earlier times under these circumstances. Any request we receive in
     proper form before these times is processed the same day. Requests we
     receive after the cutoff times are processed the next business day.
 .    The funds are open for business on each day the NYSE is open for business.
     NYSE holidays include New Year's Day, Martin Luther King, Jr. Day,
     President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
     Thanksgiving Day and Christmas Day. When any holiday falls on a weekend,
     the NYSE typically is closed on the weekday immediately before or after
     such holiday.

You can buy Fund shares:
 .    By opening an account directly with the Fund (simply complete and return a
     Wells Fargo application with proper payment);
 .    Through a brokerage account with an approved selling agent; or
 .    Through certain retirement, benefits and pension plans, or through certain
     packaged investment products (please see the providers of the plan for
     instructions).

Minimum Investments:
 .    $1,000 per Fund minimum initial investment;/1/ or
 .    $100 per Fund if you use the Systematic Purchase Program; and
 .    $100 per Fund for all investments after your first.

/1/  [Purchases of Class B shares in amounts of $250,000 or more require the
     prior approval of your selling agent.]

     We may waive the minimum for Funds you purchase through certain retirement,
     benefit and pension plans, through certain packaged investment products, or
     for certain classes of shareholders as permitted by the SEC. Check the
     specific disclosure statements and applications for the program through
     which you intend to invest.

GENERAL NOTES FOR SELLING SHARES
- -------------------------------------------------------------------------------
We determine the NAV each day as of the close of regular trading on the NYSE,
which is generally 1:00 PM (Pacific time)/3:00 P.M. (Central time). If any of
the markets for the Funds close early, the Funds may close early, and may value
their shares at earlier times under these circumstances.
- -------------------------------------------------------------------------------
Your redemptions are net of any applicable CDSC.
- -------------------------------------------------------------------------------
We will process requests to sell shares at the first NAV calculated after a
request in proper form is received. Requests received before the cutoff times
are processed on the same business day.
- -------------------------------------------------------------------------------
If your purchased shares through a packaged investment product or retirement
plan, read the directions for selling shares provided by the product or plan.
There maybe special requirements that supersede the directions in this
Prospectus.
- -------------------------------------------------------------------------------
We reserve the right to delay payment of a redemption so that we may be
reasonably certain that investments made by check or Systematic Purchase Plan
have been collected. Payments of redemptions also may be delayed under
extraordinary circumstances or as permitted by the SEC in order to protect
remaining shareholders.
- -------------------------------------------------------------------------------
Generally, we pay redemption requests in cash, unless the redemption request is
for more than $250,000 or 1% of the net assets of the Fund by a single
shareholder over any ninety-day period. If a request for a redemption is over
these limits, it may be to the detriment of existing shareholders to pay such
redemption in cash. Therefore, we may pay all or part of the redemption in
securities of equal value.

Additional Services and Other Information

Automatic Programs:
These programs help you conveniently purchase and/or redeem shares each month.
Call Investor Services 1-800-222-8222 for more information.

 .    Systematic Purchase Plan - With this program, you can regularly purchase
     shares of a Wells Fargo Fund with money automatically transferred from a
     linked bank account. Simply select the Fund you would like to purchase,
     specify an amount of at least $100, and tell us the day of the month you
     would like the money invested. If you do not specify a date, we will
     transfer the money and invest in shares of the Fund you select on or about
     the 25th day of the month.

 .    Systematic Exchange Plan - With this program, you can regularly exchange
     shares of a Wells Fargo Fund you own for shares of another Wells Fargo
     Fund. The exchange amount must be at least $100, and the exchange will take
     place on or about the 25th of each month. See the "Exchanges" section of
     this prospectus for the conditions that apply to your shares. This feature
     may not be available for certain types of accounts.

 .    Systematic Withdrawal Plan - With this program, you can regularly redeem
     shares and receive the proceeds by check or by transfer to a linked bank
     account. Simply specify an amount of at least $100 and we will sell your
     shares equal to that amount on or about the 25th of each month. To
     participate in this program, you:

     .    must have a Fund account value at $10,000 or more;
     .    must have your distributions reinvested; and
     .    may not simultaneously participate in the Systematic Purchase Plan.

It generally takes about ten days to establish a plan once we have received your
instructions. It generally takes about five days to change or cancel
participation in a plan. We automatically cancel your program if the linked bank
account your specified is closed.

Dividend and Capital Gain Distributions Options
The Funds in this Prospectus pay dividends periodically and make capital gains
distributions annually. The Funds pay any dividends quarterly.

We offer the following distribution options:

 .    Automatic Reinvestment Option - Lets you buy new shares of the same class
     of the Fund that generated the distributions. The new shares are purchased
     at NAV generally on the day the income is paid. This option is
     automatically assigned to your account unless you specify another plan.

 .    Check Payment Option - Allows you to receive checks for distributions
     mailed to your address of record or to another name and address which you
     have specified in written, signature guaranteed instructions. If checks
     remain uncashed for six months or are undeliverable by the Post Office, we
     will reinvest the distributions at the earliest date possible.

Two Things to Keep In Mind About Distributions
Remember, distributions have the effect of reducing the NAV per share by the
amount distributed. Also, distributions on new shares shortly after purchase
would be in effect a return of capital, although the distribution may still be
taxable to you.

Additional Services and Other Information (Cont'd)

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus. The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder. It
is not intended as a substitute for careful tax planning. You should consult
your tax advisor about your specific tax situation. Federal income tax
considerations are discussed further in the Statement of Additional Information.

Dividends distributed from these and the other Funds attributable to their
income from other investments and net short-term capital gain (generally, the
excess of net short-term capital gains over net long-term capital losses) will
be taxable to you as ordinary income. Corporate shareholders may be able to
deduct a portion of their dividends when determining their taxable income.

We will pass on to you any net capital gain (generally the excess of net long-
term capital gains over net short-term capital losses) earned by a Fund as a
capital gain distribution. In general, these distributions will be taxable to
you as long-term capital gains which may qualify for taxation at preferential
rates in the hands of non-corporate shareholders. Any distribution that is not
from net investment income, short term capital gains, or net capital gain may be
characterized as a return of capital to shareholders.

Table of Predecessors
The Funds in this Prospectus were created as part of the reorganization of the
Stagecoach Family of Funds, advised by Wells Fargo Bank, N.A., and the Norwest
Investment Management, Inc., into a single mutual fund complex. The
reorganization followed the merger of the advisors' parent companies.

WELLS FARGO FUNDS TRUST BALANCED FUNDS OVERVIEW

Aggressive Balanced-Equity Fund

Objective
Seeks to provide a combination of current income and capital appreciation by
diversifying investments in stocks and bonds.

Principal Strategy
We divide the Fund's investment between fixed income securities and equity
securities in varying proportions, with an emphasis on equity securities.

Growth Balanced Fund

Objective
Seeks to provide a combination of current income and capital appreciation by
diversified investments in stocks and bonds.

Principal Strategy
We divide the Fund's investment between fixed income securities and equity
securities in varying proportions, with an emphasis on equity securities.

LifePath Funds

Objective
Each LifePath Fund seeks to maximize assets available for retirement or other
purposes, consistent with the quantitatively measured risk that investors, on
average, may be willing to accept given their investment time horizon.  The
Funds with shorter time horizons (LifePath Opportunity and LifePath 2010, for
instance) will tend to be less risky and have lower expected returns than the
Fund with longer time horizons (LifePath 2030 and LifePath 2040).  Investors are
encouraged to select a particular LifePath Fund based on their investment time
horizon.  Specifically,

 .    LifePath Opportunity Fund is managed for investors who have retired or who
     are planning to retire (or begin to withdraw substantial portions of their
     investment) approximately in the year 2000.

     The Fund also may be appropriate for investors with a shorter time horizon.
     The Fund does not terminate in the Year 2000, but will continue with the
     lowest risk profile of all the LifePath Funds. It is expected that when the
     LifePath 2010 Fund's target date arrives, the LifePath 2010 Fund will be
     combined with the LifePath Opportunity Fund under the same investment
     strategy. The LifePath Opportunity Fund will continue to follow an asset
     allocation strategy that will invest approximately 20% equity securities,
     with the remainder in debt securities and cash.

 .    LifePath 2010 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2010.
 .    LifePath 2020 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2020.
 .    LifePath 2030 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2030.
 .    LifePath 2040 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2040.

                                       4
<PAGE>

Principal Strategy
We allocate and reallocate assets of each LifePath Fund among a wide range of
U.S. and international common stocks, fixed-income securities and money market
instruments according to the recommended mix suitable for each Fund's risk
level.

Moderate Balanced Fund

Objective
Seeks to provide a combination of current income and capital appreciation by
diversifying investment in stocks, bonds and other fixed income investments.

Principal Strategy
We invest in an evenly balanced mix of fixed income and equity securities.

Summary Of Important Risks

 This section summarizes important risks that are common to all of the Funds
 described in this Prospectus, and important risks that relate specifically to
 particular Funds.  Both are important to your investment choice.  Additional
 information about these and other risks is included in the individual Fund
 descriptions later in this Prospectus, under General Investment Risks beginning
 on page __ and in the Funds' Statement of Additional Information.  An
 investment in a Fund is not a deposit of Wells Fargo Bank and is not insured or
 guaranteed by the Federal Deposit Insurance Corporation or any other government
 agency.

 Common Risks for the Funds

 Equity Securities.  Each Fund invests in equity securities, which are subject
 to equity market risk.  This is the risk that stock prices will fluctuate and
 can decline and reduce the value of a Fund's portfolio.  Certain types of stock
 and certain individual stocks selected for a Fund's portfolio may underperform
 or decline in value more than the overall market.  As of the date of this
 Prospectus, the equity markets, as measured by the S&P 500 Index and other
 commonly used indexes, are trading at or close to record levels.  There can be
 no guarantee that these levels will continue.  The Funds that invest in smaller
 companies, in foreign companies (including investments made through American
 Depositary Receipts and similar instruments), and in emerging markets are
 subject to additional risks, including less liquidity and greater price
 volatility.  A Fund's investment in foreign companies and emerging markets are
 also subject to special risks associated with international investing,
 including currency, political, regulatory and diplomatic risks.

 Debt Securities.  The Funds may invest some of their assets in debt securities,
 such as notes and bonds, which are subject to credit risk and interest rate
 risk.  Credit risk is the possibility that an issuer of an instrument will be
 unable to make interest payments or repay principal.  Changes in the financial
 strength of an issuer or changes in the credit rating of a security may affect
 its value.  Interest rate risk is the risk that interest rates may increase,
 which will reduce the resale value of instruments in a Fund's portfolio,
 including U.S. Government obligations.  Debt securities with longer maturities
 are generally more sensitive to interest rate changes than those with shorter
 maturities.  Changes in market interest rates do not affect the rate payable on
 debt instruments held in a Fund, unless the instrument has adjustable or
 variable rate features, which can reduce interest rate risk.  Changes in market
 interest rates may also extend or shorten the duration of certain types of
 instruments, such as asset-backed securities, thereby affecting their value and
 the return on your investment.

Fund-Specific Risks

- -------------------------------------------------------------------------------
Fund                                   Specific Risks

- ------------------------------------------------------------------------------
Aggressive Balanced-Equity Fund        These Funds invest in smaller companies
Growth Balanced Fund                   that may be more volatile than
Moderate Balanced Fund                 investments in larger companies. Smaller
                                       companies also may have higher failure
                                       rate than larger companies. The Funds
                                       also are subject to leverage risk, which
                                       is the risk that some small transactions
                                       may multiply smaller market movements
                                       into large changes in the Fund's net
                                       asset value. This risk may occur when a
                                       Fund borrows money or enters into
                                       transactions that have a similar effect,
                                       such as short sales and forward
                                       commitment transactions. This risk also
                                       may occur when a Fund makes investment in
                                       derivatives, such as

Aggressive Balanced-Equity Fund

Investment Objective
The Aggressive Balanced-Equity Fund seeks to provide a combination of current
income and capital appreciation by diversified investments in stocks and bonds.

Investment Policies
We divide the Fund's investments between fixed income securities and equity
securities in varying proportions, with an emphasis on equity securities.  The
Fund is designed for investors seeking long-term capital appreciation in the
equity securities market in a balanced fund.  The Fund currently invests in [14]
core portfolios of Wells Fargo Core Trusts.

Permitted Investments
The equity portion of the Fund's portfolio uses the 5 different equity
investment styles.  The blending of multiple equity investment styles is
intended to reduce the risk associated with the use of a single style, which may
move in and out of favor during the course of a market cycle.  The fixed income
portion of each Balanced Fund's portfolio uses 3 or 4 different fixed income
investment styles.  The blending of multiple fixed income investment styles is
intended to reduce the price and return volatility of, and provide more
consistent returns within, the fixed income portion of the Fund.

The percentage of the Fund's assets invested in different styles may temporarily
deviate from the Fund's current allocation due to changes in market values.  The
investment advisor will effect transactions periodically to reestablish the
current allocation.

As market or other conditions change, the investment advisor may attempt to
enhance the returns of the Fund by changing the percentage of Fund assets
invested in fixed income and equity securities.  The Fund also may invest in
more or fewer Portfolios or invest directly in portfolio securities.  Absent
unstable market conditions, the investment advisor does not anticipate making a
substantial number of percentage changes.  When the investment advisor believes
that a change in the current allocation percentages is desirable, it will sell
and purchase securities to effect the change.  When the investment advisor
believes that a change will be temporary (generally, 3 years or less), it may
effect the change by using futures contracts.

Important Risk Factors
Investments in the Fund will be subject both to the risks of debt securities and
the risks of equity securities discussed in the Summary of Important Risks on
page ___.  You should also consider the General Investment Risks beginning on
page ___.  They are all important to your investment choice.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure.  In this structure,
the "gateway" Aggressive Balanced-Equity Fund invests all of its assets in
various "core" portfolios whose objectives and investment policies are
consistent with the Fund's investment objective.  Gateway funds investing in
various core portfolios can enhance their investment opportunities and reduce
their expenses through sharing the costs of managing a large pool of assets.
References to the investment activities of the Fund also refer to the investment
of the core portfolios in which it invests.

Growth Balanced Fund

Investment Objective
The Growth Balanced Fund seeks to provide a combination of current income and
capital appreciation by diversified investments in stocks and bonds.

Investment Policies
We divide the Fund's investments between fixed income securities and equity
securities in varying proportions, with an emphasis on equity securities.  The
Fund is designed for investors seeking long-term capital appreciation in the
equity securities market in a balanced fund.  The Fund currently invests in [14]
core portfolios of Wells Fargo Core Trusts.

Permitted Investments
The Fund invests the equity portion of its portfolio in the 5 different equity
investment core portfolio.  The blending of multiple equity investment styles is
intended to reduce the risk associated with the use of a single style, which may
move in and out of favor during the course of a market cycle.  The Fund invests
the fixed-income portion of its portfolio in [Positive Return Bond Portfolio,
Strategic Value Bond Portfolio, and Managed Fixed Income Portfolio.]  The
blending of multiple fixed-income investment styles is intended to reduce the
price and return volatility of, and provide more consistent returns within, the
fixed-income portion of the Fund's investments.

The percentage of the Fund's assets invested in different core portfolios may
temporarily deviate from the Fund's current allocation due to changes in market
values.  The investment advisor will effect transactions periodically to re-
establish the current allocation.

As market or other conditions change, the investment advisor may attempt to
enhance the Fund's returns by changing the percentage of Fund assets invested in
fixed-income and equity securities.  The Fund also may invest in more or fewer
Portfolios or invest directly in portfolio securities.  Absent unstable market
conditions, the Advisor does not anticipate making a substantial number of
percentage changes.  When the Advisor believes that a change in the current
allocation percentages is desirable, it will sell and purchase securities to
effect the change.  When the Advisor believes that a change will be temporary
(generally, three years or less), it may effect the change by using futures
contracts.

Important Risk Factors

the risks of equity securities discussed in the Summary of Important Risks on

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure.  In this structure,
the "gateway" Growth Balanced Fund invests all of its assets in various "core"
portfolios whose objectives and investment policies are consistent with the
Fund's investment objective.  Gateway funds investing in various core portfolios

The LifePath Funds

Investment Objective
Each LifePath Fund seeks to maximize assets available for retirement or for
other purposes consistent with the quantitatively measured risk that investors,
on average, may be willing to accept given their investment time horizons.

Investors are encouraged to select a particular LifePath Fund based on their
investment time horizon.  Specifically:

 .    LifePath Opportunity Fund is managed for investors who have retired or who
     are planning to retire (or begin to withdraw substantial portions of their
     investment) approximately in the year 2000.

     The Fund also may be appropriate for investors with a short time horizon.
     The Fund does not terminate in the Year 2000, but will continue with the
     lowest risk profile of all the LifePath Funds. It is expected that when the
     LifePath 2010 Fund's target date arrives, the LifePath 2010 Fund will be
     combined with the LifePath Opportunity Fund under the same investment
     strategy. The LifePath Opportunity Fund will continue to follow an asset
     allocation strategy that will invest approximately 20% equity securities,
     with the remainder in debt securities and cash.

 .    LifePath 2010 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2010.
 .    LifePath 2020 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2020.
 .    LifePath 2030 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2030.
 .    LifePath 2040 Fund is managed for investors planning to retire or begin to
     withdraw substantial portions of their investment approximately in the year
     2040.

Investment Policies
Each LifePath Fund holds stocks, bonds and short-term money market instruments
in proportions suggested by its own comprehensive strategy.  The strategies go
further, allocating assets among indexes and sub-categories within various
investment classes.  Some of the sub-categories are well-known broad-based
market indexes, such as the S&P 500 Index of large-company stocks, and others
were specifically created to reflect a particular market segment.  This broad
diversification is designed to produce the highest expected returns for a given
level of risk.

The LifePath Funds were the first Funds of their kind to offer a flexible
investment strategy designed to change over specific time horizons.  Typically,
long-term investment goals are pursued with a more aggressive mix of equities
and fixed-income securities than short-term goals.  The allocation of each Fund
gradually grows more conservative as the year in the Fund's title approaches.
You are encouraged to choose the LifePath Fund whose title year most closely
matches the year during which you expect to begin regularly redeeming shares.
Keep in mind, however, that the year in each Fund's title also serves as a guide
to the relative aggressiveness of each Fund, where the LifePath 2040 Fund has
the most aggressive asset allocation and the LifePath Opportunity Fund has the
least aggressive asset allocation.  If you have a low risk tolerance, you may
not wish to invest in the Life Path 2040 Fund, for example, even if you do not
expect to retire for another forty years.  Conversely, you may feel comfortable
choosing a more aggressive LifePath Fund for a near-term investment goal.

We allocate and reallocate assets among a wide range of U.S. and international
common stocks, fixed-income securities and money market instruments according to
the recommended mix suitable for each Fund's risk level.  Under normal
conditions, the LifePath Opportunity Fund will typically invest 80% of its
assets in fixed-income classes and up to 20% in equities as it seeks stable
income production and reduced

                                       13
<PAGE>

volatility. The more aggressive Funds may invest in up to 100% stocks, but as
their title year approaches, their allocation will increasingly resemble the
current allocation of the LifePath Opportunity Fund.

The LifePath Opportunity Fund will not terminate when it reaches the year 2000.
Instead, the Fund will enter its "post target" strategy during which it will
seek to maximize total return consistent with assuming the lowest risk of any
LifePath series.  The Fund will continue to follow an asset allocation strategy
among three broad investment classes:  equity and debt securities of domestic
and foreign issuers and cash in the form of money market instruments.  However,
unlike the remaining LifePath Funds with target dates, during its post target
strategy the LifePath Opportunity Fund will no longer reduce its investment risk
through time.  Instead, the Fund is expected to have a long-term average mix of
approximately 20% equity securities, with the remainder in debt securities and
cash.  In the same manner as all LifePath Funds, the LifePath Opportunity Fund
will continue to employ a tactical asset allocation component, which will alter
the investment mix to account for changing expected risks and opportunities.
When other LifePath Funds reach their target date, it is expected that
shareholders will be asked to approve combining such Funds with the LifePath
Opportunity Fund.

Asset Allocation Decisions
In buying securities for each LifePath Fund, Barclays Global Fund Advisors
("BGFA"), the Funds' investment advisor, does not select individual companies.
Instead, BGFA focuses on selecting a mix of indexes by measuring their risk
level and expected returns based on a proprietary set of criteria.  The Funds
then allocate a portion of their assets to each index appropriate for each
individual Fund.  Where possible, the Funds buy all the securities that comprise
the index.  If the index includes too many securities to buy them all, the Funds
buy a representative sample.  The Funds seek to match the index's return as
closely as possible.  The Funds focus on the selection of indexes or asset
classes and do not try to avoid individual under-performing securities
investments nor do they try to pick individual investments that might outperform
the index.

This strategy stems from the belief that asset allocation decisions -- which
index or investment category you choose -- matter more to overall investment
performance than individual security selection -- which stock or bond you
choose.

Risk Tolerance
Two general rules of investing have shaped the Funds' strategies:

 .    Higher investment return potential usually goes hand-in-hand with higher
     risk; put another way, the greater its potential for loss. Historically,
     for example, stocks have outperformed bonds, but the worst year for stocks
     on record was much worse than the worst year for bonds.
 .    The longer an investors' time horizon, the greater their risk tolerance;
     their investments have more time to recoup their losses, if any.

The LifePath Funds with longer time horizons take more risks.  This normally
gives investors the potential for greater returns than Funds with shorter time
horizons.  As a Fund approaches its time horizon, and its investors have less
time to recover from market declines, the Fund systematically reduce the level
of risk.  This systematic shift toward more stable investments should help
secure the value of your LifePath investment as the time nears for you to begin
withdrawing on it.

BGFA does not limit the analysis to long-term expectations.  The Funds also take
into account short-term market conditions.  If conditions in a market have
increased risk levels of an investment type or index to a point that its risk
outweighs its expected returns, the Funds will not allocate as much of their
assets to it as it otherwise might.  Conversely, the Funds may reduce their
allocation, even when risks have not increased, because its expected return has
fallen.  This usually happens because prices in a market have risen so high that
the potential for further gains appears limited.

Model-Driven Decisions
The Fund's assets are allocated across investment groups according to a
sophisticated mathematical model that was developed in 1993 and is continually
refined.  BGFA's investment professionals conduct ongoing research to enhance
the model and to ensure it is keeping pace with the world's constantly changing

                                       14
<PAGE>

financial markets.  Using this model, BGFA gains a consistent and objective
structure for making investment decisions.  Unlike traditional investment funds
that employ individual portfolio managers who make decisions on a more
subjective basis, BGFA applies a scientific approach to investing through the
use of such models.

After a Fund Reaches its Time Horizon
By the time a Fund reaches the decade identified by its name, it has reached its
least aggressive state in terms of building capital.  This does not mean that it
invests exclusively in money market instruments.  Rather, because BGFA believes
that most investors are still willing to take some risks in pursuing returns
even while drawing on their investments, the Fund continues to allocate a
portion of its assets to stocks and bonds, in addition to money market
instruments.  On average, BGFA expects that about 20% of the Fund's assets will
be invested in stocks, with the rest in bonds and money market instruments.

Permitted Investments
We do not select individual securities based on traditional investment analysis.
Instead, we allocate investments across as many as 17 asset classes, as
represented by the indexes listed below and money market instruments.

We use a statistical method known as "sampling" in order to try to recreate the
total return of the following stock indexes as closely as possible:

 .    The S&P/BARRA Value Stock Index, which consists primarily of large-
     capitalization of U.S. stocks with lower than average price-to-book ratios;
 .    The S&P/BARA Growth Stock Index, which consists primarily of large-
     capitalization U.S. stocks with higher than average price-to-book ratios;
 .    The Intermediate Capitalization Value Index, which consists primarily of
     medium-capitalization U.S. stocks with lower than average price-to-book
     ratios;
 .    The Intermediate Capitalization Growth Index, which consists primarily of
     medium-capitalization U.S. stocks with higher than average price-to-book
     ratios;
 .    The Intermediate Capitalization Utility Stock Index, which consists
     primarily of medium-capitalization U.S. utility stocks;
 .    The Micro Capitalization Market Index, which consists primarily of small-
     capitalization U.S. stocks;
 .    The Small Capitalization Growth Stock Index, which consists primarily of
     small-capitalization U.S. stocks with lower than average price-to-book
     ratios;
 .    The Small Capitalization Growth Stock Index, which consists primarily of
     small-capitalization U.S. stocks with higher than average price-to-book
     ratios;
 .    The Morgan Stanley Capital International Japan Index, consisting primarily
     of large-capitalization Japanese stocks; and
 .    The Morgan Stanley Capital International Europe, Australia, Far East ex-
     Japan Index, consisting primarily of non-Japanese foreign stocks.

We seek exposure to the U.S. fixed-income markets by investing in securities
representative of the following indexes:

 .    The Lehman Brothers Long-Term Government Bond Index, which consists of all
     U.S. Government bonds with maturities of at least ten years;
 .    The Lehman Brothers Intermediate-Government Bond Index, which consists of
     all U.S. Government bonds with maturities of less than ten years but more
     than one year;

     investment-grade U.S. corporate bonds with maturities of at least ten

     fixed-coupon mortgage pass-throughs issued by or backed by the U.S.
     Government or its agencies.

We seek foreign debt market exposure through investment in securities
representative of the Solomon Brothers Non-U.S. World Government Bond Index,
which consists of a range of foreign government bonds with maturities of greater
than one year.

We also invest in high-quality money market instruments, including U.S.
Government obligations, obligations of foreign and domestic banks, short-term
corporate debt instruments and repurchase agreements.

We may also invest in stocks of U.S. and foreign issuers not included in the
indexes listed above.  Foreign equity exposure may be through stocks purchased
on foreign exchanges or through American Depository Receipts or similar
instruments sold on U.S. exchanges.

In addition, under normal market conditions, we may invest:

 .    in call and put options on stock indexes, stock index futures, options on
     stock index futures, interest rate and interest rate futures contracts as a
     substitute for a comparable market position in stocks; and
 .    in interest rate and index swaps.

We are not required to keep a minimum investment in any of the asset classes,
nor are we prohibited from investing substantially all of our assets in a single
class.  The allocation may shift at any time.  As part of our investment
strategy, we may invest varying portions of our assets in money market
instruments.  In addition, we may temporarily hold assets in cash or in money
market instruments, including U.S. Government obligations, repurchase agreements
and other short-term investments, to maintain liquidity or when we believe it is
in the best interest of shareholders to do so.  Each Fund is a diversified
portfolio.

Important Risk Factors
We may incur a higher than average portfolio turnover ratio due to allocation
shifts recommended by the investment model.  Foreign obligations may entail
additional risks.  The value of investments in options on stock indexes is
affected by price level movements for a particular index, rather than price
movements for an individual issue.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

Additional Fund Facts
The allocations across asset classes are recommended by a proprietary investment
model that analyzes extensive financial and economic data, including relative
risk and return statistics.  We have broad latitude in allocating the Fund's
investments and in refining the model.  No person is primarily responsible for
recommending either the asset mix or the mix of securities within a class.  We
may invest in fewer asset classes than listed above, particularly for any Fund
with less than $150 million in total assets.

Master Feeder Structure
The LifePath Funds do not have their own investment advisor.  Instead, each
LifePath Fund invests all of its assets in a separate mutual fund, called a
Master Portfolio, that has a substantially similar investment objective as the
Fund.  BGFA serves as investment advisor to each Master Portfolio.  The Master
Portfolios may accept from other feeder funds.

Moderate Balanced Fund

Investment Objective
The Moderate Balanced Fund seeks to provide a combination of current income and
capital appreciation by diversifying investments in stocks, bonds and other
fixed income securities.

Investment Policies
The Fund is designed for investors seeking roughly equivalent exposure to fixed
income securities and equity securities.  The Fund's portfolio is evenly
balanced between fixed income and equity securities and uses a "multi-style"
approach designed to minimize the risk of investing in a single investment
style.  The Fund currently invests in [___] portfolios.

Permitted Investments
The equity portion of the Fund's portfolio uses the 5 different equity
investment styles.  The blending of multiple equity investment styles is
intended to reduce the risk associated with the use of a single style, which may
move in and out of favor during the course of a market cycle.  The fixed income
portion of each Balanced Fund's portfolio uses 3 or 4 different fixed income
investment styles.  The blending of multiple fixed income investment styles is
intended to reduce the price and return volatility of, and provide more
consistent returns within, the fixed income portion of the Fund.

The percentage of the Fund's assets invested in different styles may temporarily
deviate from the Fund's current allocation due to changes in market values.  The
investment advisor will effect transactions periodically to reestablish the
current allocation.

As market or other conditions change, the investment advisor may attempt to
enhance the returns of the Fund by changing the percentage of Fund assets
invested in fixed income and equity securities.  The Fund also may invest in
more or fewer Portfolios or invest directly in portfolio securities.  Absent
unstable market conditions, the investment advisor does not anticipate making a
substantial number of percentage changes.  When the investment advisor believes
that a change in the current allocation percentages is desirable, it will sell
and purchase securities to effect the change.  When the investment advisor
believes that a change will be temporary (generally, three years or less), it
may effect the change by using futures contracts.

Important Risk Factors
Investments in the Fund will be subject both to the risks of debt securities and
the risks of equity securities discussed in the Summary of Important Risks on
page ___.  You should also consider the General Investment Risks beginning on
page ___.  They are all important to your investment choice.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure.  In this structure,
the "gateway" Moderate Balanced Fund invests all of its assets in various "core"
portfolios whose objectives and investment policies are consistent with the
Fund's investment objective.  Gateway funds investing in various core portfolios
can enhance their investment opportunities and reduce their expenses through
sharing the costs of managing a large pool of assets.  References to the
investment activities of the Fund also refer to the investments of the core
portfolios in which it invests.

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds.  Certain common risks are identified in the
Summary of Important Risks on page ___.  Other risks of mutual fund investing
include the following:

 .    Unlike bank deposits, such as CDs or savings accounts, mutual funds are not
     insured by the FDIC.
 .    We cannot guarantee that we will meet our investment objectives.
 .    We do not guarantee the performance of a Fund, nor can we assure you that
     the market value of your investment will not decline. We will not "make
     good" any investment loss you may suffer, nor can anyone we contract with
     to provide certain services, such as selling agents or investment advisors,
     offer or promise to make good any such losses.
 .    Share prices -- and therefore the value of your investment -- will increase
     and decrease with changes in the value of the underlying securities and
     other investments. This is referred to as price volatility.
 .    Investing in any mutual fund, including those deemed conservative, involves
     risk, including the possible loss of any money you invest.
 .    An investment in a single Fund, by itself, does not constitute a complete
     investment plan.
 .    The Funds that invest in smaller companies, foreign companies (including
     investments made through American Depositary Receipts and similar
     instruments), and in emerging markets are subject to additional risks,
     including less liquidity and greater price volatility. A Fund's investment
     in foreign and emerging markets may also be subject to special risks
     associated with international trade, including currency, political,
     regulatory and diplomatic risk.
 .    The Funds may invest a portion of their assets in U.S. Government
     obligations. It is important to recognize that the U.S. Government does not
     guarantee the market value or current yield of those obligations. Not all
     U.S. Government obligations are backed by the full faith and credit of the
     U.S. Treasury, and the U.S. Government's guarantee does not extend to the
     Funds themselves.
 .    The Funds may also use certain derivative instruments, such as options or
     futures contracts. The term "derivatives" covers a wide number of
     investments, but in general it refers to any financial instrument whose
     value is derived, at least in part, from the price of another security or a
     specified index, asset or rate. Some derivatives may be more sensitive to
     interest rate changes or market moves, and some may be susceptible to
     changes in yields or values due to their structure or contract terms.
 .    The Funds may temporarily hold assets in cash or in money market
     instruments, including U.S. Government obligations, shares of other mutual
     funds and repurchase agreements, or make other short-term investments,
     either to maintain liquidity or for short-term defensive purposes when we
     believe it is in the best interests of shareholders to do so. Except with
     respect to money market Funds, to the extent a Fund's assets are so
     invested, they may cause a Fund to not achieve its investment objective.
     This practice is expected to have limited, if any, effect on the Funds'
     pursuit of their objectives over the long term.
 .    The Funds may invest a portion of their assets in U.S. Government
     obligations, such as securities issued or guaranteed by the Government
     National Mortgage Association ("GNMAs"), the Federal National Mortgage
     Association ("FNMAs") and the Federal Home Loan Mortgage Corporation
     ("FHLMCs"). Each are mortgage-backed securities representing partial
     ownership of a pool of residential mortgage loans. A "pool" or group of
     such mortgages is assembled and, after being approved by the issuing or
     guaranteeing entity, is offered to investors through securities dealers.
     Mortgage-backed securities are subject to prepayment and extension risk,
     which can alter the maturity of the securities and also reduce the rate of
     return on the portfolio. Collateralized mortgage obligations ("CMOs")
     typically represent principal-only and interest-only portions of such
     securities and are subject to increased interest-rate and credit risk.
 .    The market value of lower-rated debt securities and unrated securities of
     comparable quality that the Funds may invest in tends to reflect individual
     developments affecting the issuer to a greater extent than the market value
     of higher-rated securities, which react primarily to fluctuations in the
     general level of interest rates. Lower-rated securities also tend to be
     more sensitive to economic conditions than higher-rated securities. These
     lower-rated debt securities are considered by the rating agencies,

                                       18
<PAGE>

     on balance, to be predominantly speculative with respect to the issuer's
     capacity to pay interest and repay principal. These securities generally
     involve more credit risk than securities in higher-rating categories. Even
     securities rated "BBB" by S&P or by Moody's ratings which are considered
     investment-grade, possess some speculative characteristics.

Investment practices and risk levels are carefully monitored.  Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.



What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Fund and a table showing some of the
additional investment practices that each Fund may use and the risks associated
with them.  Additional information about these practices is available in the
Statement of Additional Information.

Counter-Party Risk--The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

Credit Risk--The risk that the issuer of a debt security will be unable to
make interest payments or repay principal on schedule.  If an issuer does
default, the affected security could lose all of its value, or be renegotiated
at a lower interest rate or principal amount.  Affected securities might also
lose liquidity.  Credit risk also includes the risk that a party in a
transaction may not be able to complete the transaction as agreed.

Currency Risk--The risk that a change in the exchange rate between U.S. dollars
and a foreign currency may reduce the value of an investment made in a security
denominated in that foreign currency.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value of
liquidity of investments in either country.

Emerging Market Risk--The risk that the emerging market, as defined in the
glossary, may be more sensitive to certain economic changes.  For example,
emerging market countries are often dependent on international trade and are
therefore often vulnerable to recessions in other countries.  They may have
obsolete financial systems, have volatile currencies and may be more sensitive
than more mature markets to a variety of economic factors.  Emerging market
securities may also be less liquid than securities of more developed countries
and could be difficult to sell, particularly during a market downturn.

Experience Risk--The risk presented by a new or innovative security.  The risk
is that insufficient experience exists to forecast how the security's value
might be affected by various economic conditions:

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security.  Generally, when interest rates increase, the value of
a debt security decreases.  The effect is usually more pronounced for securities
with longer dates to maturity.

Leverage Risk--The risk that a practice may increase a Fund's exposure to market
risk, interest rate risk or other risks by, in effect, increasing assets
available for investment.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of a stock, bond or other security will be
reduced by market activity.  This is a basic risk associated with all
securities.

                                       19
<PAGE>

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

Prepayment Risk--The risk that consumers will accelerate their prepayment of
mortgage loans or other receivables, which can shorten the maturity of a
mortgage-based or other asset-backed security and reduce a portfolio's rate of
return.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.  Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Year 2000 Risk--The Funds' principal service providers have advised the Funds
that they are working on the necessary changes to their computer systems to
avoid any system failure based on an inability to distinguish the year 2000 from
the year 1900, and that they expect their systems to be adapted in time.  There
can, of course, be no assurance of success.  In addition, the companies or
entities in which the Funds invest also could be adversely impacted by the Year
2000 issue, especially foreign entities, which may be less prepared for Year
2000.  The extent of such impact cannot be predicted.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund.  You should also
see the Statement of Additional Information for additional information about the
investment practices and risks particular to each Fund.

Organization and Management of the Funds

A number of different entities provide services to the Funds.  This section
shows how the Funds are organized, lists the entities that perform different
services, and explains how their service providers are compensated.  Further
information is available in the Statement of Additional Information for the
Funds.

About Wells Fargo Funds Trust
Each Fund is one of over 60 Funds of Wells Fargo Funds Trust (the "Trust"), an
open-end management investment company.  The Trust was organized on March 10,
1999, as a Delaware business trust. The Board of Trustees of the Trust
supervises each Fund's activities, monitors its contractual arrangements with
various service providers and decides upon matters of general policy.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds.  The holding company of Wells Fargo Bank, the investment advisor to
the Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998.  Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one Stagecoach and/or
Norwest Advantage Funds.  The performance and financial statement history of
each predecessor Fund will be assumed by the Wells Fargo Funds Trust Fund.  The
succession transactions are conditioned on shareholder approval by the
shareholders of the various Stagecoach and Norwest Advantage Funds.  The Table
on page __ identifies the Stagecoach and Norwest predecessors to the Funds.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund class paid on an annual basis for the
services described.

Organization and Management of the Funds (Cont'd)

The Investment Advisor
Wells Fargo Bank provides portfolio management and fundamental security analysis
services as the advisor for the Aggressive Balanced-Equity, Growth Balanced and
Moderate Balanced Funds. Wells Fargo Bank, founded in 1852, is the oldest bank
in the western United States and is one of the largest banks in the United
States. Wells Fargo Bank is a wholly owned subsidiary of Wells Fargo & Company,
a national bank holding company. As of December 31, 1998, Wells Fargo Bank and
its affiliates managed over $202 billion in assets.

The Aggressive Balanced-Equity, Growth Balanced and Moderate Balanced Funds are
gateway Funds that invest in various core portfolios. Wells Fargo Bank is
entitled to receive an investment advisory fee of .25% of each Fund's average
annual net assets for providing advisory services to each Fund including each
Fund's investments in the various core portfolios. Wells Fargo Bank also acts as

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:
 .  As with all mutual fund investments, the price you pay to purchase shares or
   the price you receive when you redeem shares is not determined until after a
   request has been received in proper form.
 .  We determine the Net Asset Value ("NAV") of each Funds' shares each business
   day as of the close of regular trading on the NYSE. We determine the NAV by
   subtracting Fund liabilities from its total assets, and then dividing the
   result by the total number of outstanding shares of that Fund. Each Fund's
   assets are generally valued at current market prices. See the Statement of
   Additional Information for further disclosure.
 .  We process requests to buy or sell shares of the Funds each business day as
   of the close of regular trading on the New York Stock Exchange ("NYSE"),
   which is usually 1:00 p.m. (Pacific time)/3:00 p.m. (Central time). If the
   markets close early, the Funds may close early and may value their shares at
   earlier times under these circumstances. Any request we receive in proper
   form before the close of regular trading on the NYSE is processed the same
   day. Requests we receive after the cut off are processed the next business
   day.
 .  The Funds are open for business on each day the NYSE is open for business.
   NYSE holidays include New Year's Day, Martin Luther King, Jr. Day,
   President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
   Thanksgiving Day and Christmas Day. When any holiday falls on a weekend, the
   NYSE typically is closed on the weekday immediately before or after such
   holiday.

Typically, Institutional Class shares are bought and held on your behalf by the
Institution through which you are investing. Check with your customer account
representative or your Customer Account Agreement for the rules governing your
investment.

Minimum Investments:
 .  Minimum, initial and subsequent investment amounts are determined by your
   Customer Account Agreement with your Institution, and are generally:
   .  $2,000,000 per Fund minimum initial investment.

How to Buy Shares
You can open a Fund account and buy Fund shares through an Institution through
which you have established a Customer Account. Investors interested in
purchasing Institutional shares of the Funds should contact an account
representative at their Institution and should understand the following:

 .  Share purchases are made through a Customer Account at an Institution in
   accordance with the terms of the Customer Account involved;
 .  Institutions are usually the holders of record of Institutional shares held
   through Customer Accounts and maintain records reflecting their customers'
   beneficial ownership of the shares;
 .  Institutions are responsible for transmitting their customers' purchase and
   redemption orders to the Funds and for delivering required payment on a
   timely basis;
 .  The exercise of voting rights and the delivery of shareholder communications
   from the Funds is governed by the terms of the Customer Account involved; and
 .  Institutions may charge their customers account fees and may receive fees
   from us with respect to investments their customers have made with the Funds.
   See "Organization and Management of the Funds" for further details about
   these fees.

                                       27

Your Account (Cont'd)

How to Sell Shares
Institutional shares must be redeemed in accordance with the account agreement
governing your Customer Account at the Institution. Please read the Customer
Account agreement with your Institution for rules governing selling shares.

General notes for selling shares
 .  We process requests we receive from an Institution in proper form before the
   close of the NYSE, usually 1:00 P.M. Pacific time, at the NAV determined on
   the same business day. Requests we receive after this time are processed on
   the next business day.
 .  Redemption proceeds are usually wired to the redeeming Institution the
   following business day.
 .  We reserve the right to delay payment of a redemption for up to 15 days so
   that we may be reasonably certain that investments made by check have been
   collected. Payments of redemptions also may be delayed under extraordinary
   circumstances or as permitted by the SEC in order to protect remaining
   shareholders. Payments of redemptions also may be delayed up to seven days
   under normal circumstances, although it is not our policy to delay such
   payments.
 .  Generally, we pay redemption requests in cash, unless the redemption requests
   is for more than $250,000 or 1% of the net assets of the Fund by a single
   shareholder over a ninety-day period. If a request for a redemption is over
   these limits it may be to the detriment of existing shareholders. Therefore,
   we may pay the redemption in part on in whole in securities of equal value.

Exchanges

Exchanges between Wells Fargo Funds are two transactions: a sale of one Fund and
the purchase of another. In general, the same rules and procedures that apply to
sales and purchases apply to exchanges. There are, however, additional factors
you should keep in mind while making or considering an exchange:

 .  You should carefully read the Prospectus for the Fund into which you wish to
   exchange.
 .  Every exchange involves selling Fund shares and that sale may produce a
   capital gain or loss for federal income tax purposes.
 .  If you are making an initial investment into a new Fund through an exchange,
   you must exchange at least the minimum first purchase amount of the Fund you
   are redeeming, unless your balance has fallen below that amount due to market
   conditions.
 .  Any exchange between Funds you already own must meet the minimum redemption
   and subsequent purchase amounts for the Funds involved.
 .  In order to discourage excessive Fund transaction expenses that must be borne
   by other shareholders, we reserve the right to limit or reject exchange
   orders. Generally, we will notify you 60 days in advance of any changes in
   your exchange privileges.
 .  You may make exchanges only between like share classes.
 .  Exchange into Money Market Fund Class B shares are subject to certain
   restrictions in addition to those described above.

Additional Services and Other Information

Dividend and Capital Gain Distributions
The Funds in this Prospectus pay dividends quarterly and make capital gains
distributions at least annually.

Distributions paid by a Fund are automatically reinvested to purchase new shares
of the Funds. The new shares are purchased at NAV, generally on the day
distributions are paid.

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus. The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder. It
is not intended as a substitute for careful tax planning. You should consult
your tax advisor about your specific tax situation. Federal income tax
considerations are discussed further in the Statement of Additional Information.

Dividends distributed from these and the other Funds attributable to their
income from other investments and net short-term capital gain (generally, the
excess of net short-term capital gains over net long-term capital losses) will
be taxable to you as ordinary income. Corporate shareholders may be able to
deduct a portion of their dividends when determining their taxable income.

We will pass on to you any net capital gain (generally the excess of net long-
term capital gains over net short-term capital losses) earned by a Fund as a
capital gain distribution. In general, these distributions will be taxable to
you as long-term capital gains which may qualify for taxation at preferential
rates in the hands of non-corporate shareholders.

In general, all distributions will be taxable to you when paid even if they are
paid in additional Fund shares. However, distributions declared in October,
November and December are distributed by the following January will be taxable
as if they were paid on December 31 of the year in which they were declared. We
will notify you annually as to the status of your Fund distributions.

If you buy shares of a Fund shortly before it makes a distribution, your
distribution from the Fund will, in effect, be a taxable return of part of your
investment. Similarly, if you buy shares of a Fund that holds appreciated
securities in its portfolio, you will receive a taxable return of part of your
investment if and when the Fund sells the appreciated securities and realizes
the gain. Some of the Funds have built up, or have the potential to build up,
high levels of unrealized appreciation.

Your redemptions (including redemptions in-kind) and exchanges of Fund shares
will ordinarily result in a taxable capital gain or loss, depending on the
amount you receive for your shares (or are deemed to receive in the case of
exchanges) and the amount you paid (or are deemed to have paid) for them.

Foreign shareholders may be subject to different tax treatment, including
withholding taxes. In certain circumstances, U.S. residents may also be subject
to backup withholding at a 31% rate on distributions from and redemption
proceeds paid by a Fund.

                             Table of Predecessors

The Funds described in this Prospectus were created as part of the
reorganization of the Stagecoach Family of Funds, advised by Wells Fargo Bank,
N.A., and the Norwest Advantage Family of Funds, advised by Norwest Investment
Management, Inc., into a single mutual fund complex. The reorganization followed
the merger of the advisors' parent companies.

("Norwest"), the Board of Directors of Stagecoach Funds, Inc. ("Stagecoach") and
the Board of Trustees of the Trust approved an Agreement and Plan of
Reorganization providing for, among other things, the transfer of the assets and
stated liabilities of various predecessor Norwest and Stagecoach portfolios to
the Funds.  Prior to September 17, 1999, the effective date of the consolidation
of the Funds and the predecessor Norwest and Stagecoach portfolios (the
"Consolidation"), the Funds had only nominal assets.

     The Aggressive Balanced Equity Fund will commence operations on September
17, 1999, as successor to the Norwest Advantage Aggressive Balanced Equity Fund.
The Norwest Advantage Aggressive Balanced Equity Fund commenced operations on
December 2, 1997.

     The Growth Balanced Fund will commence operations on September 17, 1999, as
successor to the Norwest Advantage Growth Balanced Fund.  The predecessor
Norwest Advantage Growth Balanced Fund commenced operations on April 30, 1989.

     The Index Allocation Fund will commence operations on September 17, 1999,
as successor to the Index Allocation Fund of Stagecoach.  The predecessor
Stagecoach Index Allocation Fund was originally organized on April 7, 1988 as
the Asset Allocation Fund of Overland Express Funds, Inc. ("Overland"), another
open-end management investment company advised by Wells Fargo Bank.  The
Overland Asset Allocation Fund changed its name to the Index Allocation Fund on
February 14, 1997.  On July 23, 1997, the Boards of the Directors of the Company
and Overland approved an Agreement and Plan of Consolidation providing for,
among other things, the transfer of the assets and stated liabilities of the
predecessor Overland portfolio to the Fund.  Prior to December 12, 1997, the
effective date of the consolidation of the Company and Overland (the
"Consolidation"), the Fund had only nominal assets.  As a result of the
Consolidation, the Overland Index Allocation Fund was reorganized as the
Company's Index Allocation Fund on December 12, 1997, and shareholders of the
Overland Index Allocation Fund's Class A and Class D shares became Class A and
Class C shareholders, respectively, of the Company's Index Allocation Fund.

     The LifePath Funds will commence operations on September 17, 1999, as
successors to the Stagecoach LifePath Funds.  The Stagecoach LifePath Funds
commenced operations on [_____________, 19__].

     The Moderate Balanced Fund will commence operations on September 17, 1999,
as successor to the Norwest Advantage Moderate Balanced Fund.  The predecessor
Norwest Advantage Moderate Balanced Fund commenced operations on April 30, 1989.

                            INVESTMENT RESTRICTIONS

     Fundamental Investment Policies
     -------------------------------

     Each Fund has adopted the following investment restrictions, all of which
are fundamental policies; that is, they may not be changed, without approval by
the holders of a majority (as defined in the Investment Company Act of 1940, as
amended (the "1940 Act")) of the outstanding voting securities of such Fund.

The Funds may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of a Fund's investments in that industry would equal 25% of
the current value of the Fund's total assets, provided that there is no
limitation with respect to investment in securities issued or guaranteed by the
United States Government, its agencies or instrumentalities;

     (2)  purchase securities of any issuer if, as a result, with respect to 75%
of a Fund's total assets, more than 5% of the value of its total assets would be
invested in the securities of any one issuer or, with respect to 100% of its
assets, the Fund's ownership would be more than 10% of the outstanding voting
securities of such issuer.  This policy does not restrict a Fund's ability to
invest in securities issued or guaranteed by the U.S. Government, its agencies
and instrumentalities; or to invest substantially all of its assets in  the
portfolio of one or more open-end management investment companies pursuant to
Section 12 of the 1940 Act and the rules thereunder;

     (3)  borrow money except to the extent permitted by the 1940 Act, and the
rules, regulations and exemptions thereunder;

     (4)  issue senior securities  except to the extent permitted by the 1940
Act, and the rules, regulations and exemptions thereunder;

     (5)  make loans to other parties if, as a result, the aggregate value of
such loans would exceed one-third of a Fund's total assets.  For the purposes of
this limitation, entering into repurchase agreements, lending securities and
acquiring any debt securities are not deemed to be the making of loans;

     (6)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer and the later disposition of such securities in
accordance with a Fund's investment program may be deemed to be an underwriting;

     (7)  purchase or sell real estate unless acquired as a result of ownership
of securities or other instruments (but this shall not prevent the Fund from
investing in securities or other instruments backed by real estate or securities
of companies engaged in the real estate business); nor

                                       2
<PAGE>

     (8)  purchase or sell physical commodities unless acquired as a result of
ownership of securities or other instruments (but this shall not prevent the
Funds from purchasing or selling options and futures contracts, or from
investing in securities or other instruments backed by physical commodities.

                                       3
<PAGE>

     Non-Fundamental Investment Policies
     -----------------------------------

     Each Fund has adopted the following non-fundamental policies which may be
changed by a vote of a majority of the Trustees of the Trust or at any time
without approval of such Fund's shareholders.

     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of the 1940 Act, the rules thereunder, and
any orders obtained thereunder now or in the future. Funds in a master/feeder or
core/gateway structure, such as the Income Equity Fund, generally invest in the
securities of one or more open-end management investment companies pursuant to
various provisions of the 1940 Act. Other investment companies in which the
Funds invest can be expected to charge fees for operating expenses, such as
investment advisory and administration fees, that would be in addition to those
charged by a Fund.

     (2)  Each Fund may not invest or hold more than 15% of the Fund's net
assets in illiquid securities. For this purpose, illiquid securities include,
among others, (a) securities that are illiquid by virtue of the absence of a
readily available market or legal or contractual restrictions on resale, (b)
fixed time deposits that are subject to withdrawal penalties and that have
maturities of more than seven days, and (c) repurchase agreements not terminable
within seven days.

     (3)  Each Fund may invest in futures or options contracts regulated by the
CFTC for (i) bona fide hedging purposes within the meaning of the rules of the
CFTC and (ii) for other purposes if, as a result, no more than 5% of the Fund's
net assets would be invested in initial margin and premiums (excluding amounts
"in-the-money") required to establish the contracts.

          Each Fund (i) will  not hedge more than [50%] of its total assets by
futures contracts, buying put options, and writing call options (so
called "short positions"),  (ii) will not buy futures contracts or write put
options whose underlying value exceeds [25%] of the Fund's total assets, and
(iii) will not buy call options with a value exceeding [5%] of the Fund's total
assets.

     (4)  Each Fund may lend securities from its portfolio to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) up to
the limits established by and under the 1940 Act, including any exemptive relief
obtained thereunder, which limits are currently generally one-third of a Fund's
total assets. Any such loans of portfolio securities will be fully
collateralized based on values that are marked to market daily. [A Fund will not
enter into any portfolio security lending arrangement having a duration of
longer than one year.]

     (5)  Each Fund may not make investments for the purpose of exercising
control or management. (Investments by the Fund in entities created under the
laws of foreign countries solely to facilitate investment in securities in that
country will not be deemed the making of investments for the purpose of
exercising control.)

     (6)  Each Fund may not purchase securities on margin (except for short-term
credits necessary for the clearance of transactions).

                                       4
<PAGE>

     (7)  Each Fund may not sell securities short, unless it owns or has the
right to obtain securities equivalent in kind and amount to the securities sold
short (short sales "against the box"), and provided that transactions in futures
contracts and options are not deemed to constitute selling securities short.

     (8)  Each Fund may not purchase interests, leases, or limited partnership
interests in oil, gas, or other mineral exploration or development
programs.

ADDITIONAL PERMITTED INVESTMENT ACTIVITIES AND ASSOCIATED RISKS

     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

     Asset-Backed Securities
     -----------------------

     The Funds may invest in various types of asset-backed securities.  Asset-
backed securities are securities that represent an interest in an underlying
security.  The asset-backed securities in which the Funds invest may consist of
undivided fractional interests in pools of consumer loans or receivables held in
trust. Examples include certificates for automobile receivables (CARS) and
credit card receivables (CARDS). Payments of principal and interest on these
asset-backed securities are "passed through" on a monthly or other periodic
basis to certificate holders and are typically supported by some form of credit
enhancement, such as a surety bond, limited guaranty, or subordination. The
extent of credit enhancement varies, but usually amounts to only a fraction of
the asset-backed security's par value until exhausted. Ultimately, asset-backed
securities are dependent upon payment of the consumer loans or receivables by
individuals, and the certificate holder frequently has no recourse to the entity
that originated the loans or receivables. The actual maturity and realized yield
will vary based upon the prepayment experience of the underlying asset pool and
prevailing interest rates at the time of prepayment. Asset-backed securities are
relatively new instruments and may be subject to greater risk of default during
periods of economic downturn than other instruments. Also, the secondary market
for certain asset-backed securities may not be as liquid as the market for other
types of securities, which could result in a Fund experiencing difficulty in
valuing or liquidating such securities.  The Funds may also invest in securities
backed by pools of mortgages.  The investments are described under the heading
"Mortgage-Related Securities."

     Bank Obligations
     ----------------

     The Funds, except the Index Allocation Fund, may invest in bank
obligations, including certificates of deposit, time deposits, bankers'
acceptances and other short-term obligations of domestic banks, foreign
subsidiaries of domestic banks, foreign branches of domestic banks, and domestic
and foreign branches of foreign banks, domestic savings and loan associations
and other banking institutions.  With respect to such securities issued by
foreign branches of domestic banks, foreign subsidiaries of domestic banks, and
domestic and foreign branches of foreign banks, a Fund may be subject to
additional investment risks that are different in some respects from those
incurred by a Fund which invests only in debt obligations of U.S. domestic
issuers.  Such risks include possible future political and economic
developments, the possible

                                       5
<PAGE>

imposition of foreign withholding taxes on interest income payable on the
securities, the possible establishment of exchange controls or the adoption of
other foreign governmental restrictions which might adversely affect the payment
of principal and interest on these securities and the possible seizure or
nationalization of foreign deposits. In addition, foreign branches of U.S. banks
and foreign banks may be subject to less stringent reserve requirements and to
different accounting, auditing, reporting and recordkeeping standards than those
applicable to domestic branches of U.S. banks.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate.  Time
deposits which may be held by a Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation ("FDIC").  Bankers' acceptances are
credit instruments evidencing the obligation of a bank to pay a draft drawn on
it by a customer.  These instruments reflect the obligation both of the bank and
of the drawer to pay the face amount of the instrument upon maturity.  The other
short-term obligations may include uninsured, direct obligations, bearing fixed,
floating- or variable-interest rates.

     Below Investment Grade Investments
     ----------------------------------

     The Aggressive Balanced-Equity, Growth Balanced and Moderate Balanced Funds
may invest in debt securities that are in low or below investment grade
categories, or are unrated or in default at the time of purchase.  Such debt
securities have a much greater risk of default (or in the case of bond currently
in default, of not returning principal) and are more volatile than higher-rated
securities of similar maturity.  The value of such debt securities will be
affected by overall economic conditions, interest rates, and the
creditworthiness of the individual issuers.  Additionally, these lower rated
debt securities may be less liquid and more difficult to value than higher rated
securities.

     Stocks of the smaller and medium-sized companies in which the Fund may
invest may be more volatile than larger company stocks.  Investments in foreign
markets may also present special risks, including currency, political,
diplomatic, regulatory and liquidity risks.

     Bonds
     -----

     Certain of the debt instruments purchased by the Funds, except the LifePath
Funds, may be bonds.  The Funds invests no more than 25% in bonds that are below
investment grade.  A bond is an interest-bearing security issued by a company or
governmental unit. The issuer of a bond has a contractual obligation to pay
interest at a stated rate on specific dates and to repay principal (the bond's
face value) periodically or on a specified maturity date. An issuer may have the
right to redeem or "call" a bond before maturity, in which case the investor may
have to reinvest the proceeds at lower market rates.  The value of fixed-rate
bonds will tend to fall when interest rates rise and rise when interest rates
fall.  The value of "floating-rate" or "variable-rate" bonds, on the other hand,
fluctuate much less in response to market interest rate movements than the value
of fixed rate bonds.

                                       6
<PAGE>

     Bonds may be senior or subordinated obligations. Senior obligations
generally have the first claim on a corporation's earnings and assets and, in
the event of liquidation, are paid before subordinated debt. Bonds may be
unsecured (backed only by the issuer's general creditworthiness) or secured
(also backed by specified collateral).

     Borrowing
     ---------

     The Aggressive Balanced-Equity, Growth Balanced and Moderate Balanced Funds
may borrow money for temporary or emergency purposes, including the meeting of
redemption requests, in amounts up to 33 1/3 percent of the Fund's total assets.
Borrowing involves special risk considerations.  Interest costs on borrowings
may fluctuate with changing market rates of interest and may partially offset or
exceed the return earned on borrowed funds (or on the assets that were retained
rather than sold to meet the needs for which funds were borrowed).  Under
adverse market conditions, a Fund might have to sell portfolio securities to
meet interest or principal payments at a time when investment considerations
would not favor such sales.  Except as otherwise noted, no Fund may purchase
securities of investment while any borrowing equaling five percent or more of
the Fund's total assets in outstanding or borrow for purposes other than meeting
redemptions in an amount exceeding five percent of the value of the Fund's total
assets.  A Fund's use of borrowed proceeds to make investments would subject the
Fund to the risks of leveraging.  Reverse repurchase agreements, short sales not
against the box, dollar roll transactions and other similar investments that
involve a form of leverage have characteristics similar to borrowings but are
not considered borrowings if the Fund maintains a segregated account.

     Convertible Securities
     ----------------------

     The Aggressive Balanced-Equity, Growth Balanced and Moderate Balanced Funds
may invest in convertible securities.  A convertible security is generally a
debt obligation or preferred stock that may be converted within a specified
period of time into a certain amount of common stock of the same or a different
user.  A convertible security provides a fixed-income stream and the
opportunity, through its conversion feature, to participate in the capital
appreciation resulting from a market price advance in its underlying common
stock.  As with a straight fixed-income security, a convertible security tends
to increase in market value when interest rates decline and decrease in value
when interest rates rise.  Like a common stock, the value of a convertible
security also tends to increase as the market value of the underlying stock
rises, and it tends to decrease as the market value of the underlying stock
declines.  Because its value can be influenced by both interest rate and market
movements, a convertible security is not as sensitive to interest rats as a
similar fixed-income security, nor is it as sensitive to changes in share price
as its underlying stock.

     The creditworthiness of the issuer of a convertible security may be
important in determining the security's true value.  This is because the holder
of a convertible security will have recourse only to the issuer.  In addition, a
convertible security may be subject to redemption by the issuer, but only after
a specified date and under circumstances established at the time the security is
issued.

     While the Funds use the same criteria to rate a convertible debt security
that it uses to rate a more conventional debt security, a convertible preferred
stock is treated like a preferred stock

                                       7
<PAGE>

for a Funds' financial reporting, credit rating, and investment limitation
purposes. A preferred stock is subordinated to all debt obligations in the event
of insolvency, and an issuer's failure to make a dividend payment is generally
not an event of default entitling the preferred shareholder to take action. A
preferred stock generally has no maturity date, so that its market value is
dependent on the issuer's business prospects for an indefinite period of time.
In addition, distributions from preferred stock are dividends, rather than
interest payments, and are usually treated as such for corporate tax purposes.

     Derivative Securities
     ---------------------

     The Index Allocation Fund may invest in various instruments that may be
considered "derivatives," including structured notes, bonds or other instruments
with interest rates that are determined by reference to changes in the value of
other interest rates, indices or financial indicators ("References") or the
relative change in two or more References.  Some derivative securities represent
relatively recent innovations in the bond markets, and the trading market for
these instruments is less developed than the markets for traditional types of
debt instruments. It is uncertain how these instruments will perform under
different economic and interest rate scenarios. Because certain of these
instruments are leveraged, their market values may be more volatile than other
types of bonds and may present greater potential for capital gain or loss.
Derivative securities and their underlying instruments may experience periods of
illiquidity, which could cause a Fund to hold a security it might otherwise sell
or could force the sale of a security at inopportune times or for prices that do
not reflect current market value. The possibility of default by the issuer or
the issuer's credit provider may be greater for these structured and derivative
instruments than for other types of instruments.  As new types of derivative
securities are developed and offered to investors, the advisor will, consistent
with the Funds' investment objective, policies and quality standards, consider
making investments in such new types of derivative securities.

     Dollar Roll Transactions
     ------------------------

     The Aggressive Balanced-Equity, Growth Balanced and Moderate Balanced Funds
may enter into "dollar roll" transactions wherein the Fund sells fixed income
securities, typically mortgage-backed securities, and makes a commitment to
purchase similar, but not identical, securities at a later date from the same
party.  Like a forward commitment, during the roll period no payment is made for
the securities purchased and no interest or principal payments on the security
accrue to the purchaser, but the Fund assumes the risk of ownership.  A Fund is
compensated for entering into dollar roll transactions by the difference between
the current sales price and the forward price for the future purchase, as well
as by the interest earned on the cash proceeds of the initial sale.  Like other
when-issued securities or firm commitment agreements, dollar roll transactions
involve the risk that the market value of the securities sold by the Fund may
decline below the price at which a Fund is committed to purchase similar
securities.  In the event the buyer of securities under a dollar roll
transaction becomes insolvent, the Funds use of the proceeds of the transaction
may be restricted pending a determination by the other party, or its trustee or
receiver, whether to enforce the Funds obligation to repurchase the securities.
The Funds will engage in roll transactions for the purpose of acquiring
securities for its portfolio and not for investment leverage.  Each Fund will
limit its obligations on dollar roll transactions to 35 percent of the Fund's
net assets.

                                       8
<PAGE>

     Fixed-Income Securities
     -----------------------

     Investors should be aware that even though interest-bearing securities are
investments which promise a stable stream of income, the prices of such
securities are inversely affected by changes in interest rates and, therefore,
are subject to the risk of market price fluctuations.  Long-term securities are
affected to a greater extent by interest rates than shorter-term securities.
The values of fixed-income securities also may be affected by changes in the
credit rating or financial condition of the issuing entities.  Once the rating
of a portfolio security has been changed to a rating below investment grade, the
particular LifePath Master Portfolio considers all circumstances deemed relevant
in determining whether to continue to hold the security.  Certain securities
that may be purchased by the LifePath Master Portfolio, such as those rated
"Baa" by Moody's Investors Service, Inc. ("Moody's") and "BBB" by Standard &
Poor's Ratings Group ("S&P"), Fitch Investors Service, Inc. ("Fitch") and Duff &
Phelps Credit Rating Co. ("Duff"), may be subject to such risk with respect to
the issuing entity and to greater market fluctuations than certain lower
yielding, higher rated fixed-income securities.  Securities which are rated
"Baa" by Moody's are considered medium-grade obligations; they are neither
highly protected nor poorly secured, and are considered by Moody's to have
speculative characteristics.  Securities rated "BBB" by S&P are regarded as
having adequate capacity to pay interest and repay principal, and, while such
debt securities ordinarily exhibit adequate protection parameters, adverse
economic conditions or changing circumstances are more likely to lead to a
weakened capacity to pay interest and repay principal for securities in this
category than in higher rated categories.  Securities rated "BBB" by Fitch are
considered investment grade and of satisfactory credit quality; however, adverse
changes in economic conditions and circumstances are more likely to have an
adverse impact on these securities and, therefore, impair timely payment.
Securities rated "BBB" by Duff have below average protection factors but
nonetheless are considered sufficient for prudent investment.  If a security
held by an LifePath Master Portfolio is downgraded to a rating below investment
grade, such Master Portfolio may continue to hold the security until such time
as BGFA determines it to be advantageous for the LifePath Master Portfolio to
sell the security.  If such a policy would cause an LifePath Master Portfolio to
have 5% or more of its net assets invested in securities that have been
downgraded below investment grade, the Master Portfolio promptly would seek to
dispose of such securities in an orderly manner.

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds may purchase floating- and  variable-rate obligations such as
demand notes and bonds.  Variable-rate demand notes include master demand notes
that are obligations that permit a Fund to invest fluctuating amounts, which may
change daily without penalty, pursuant to direct arrangements between the Fund,
as lender, and the borrower.  The interest rate on a floating-rate demand
obligation is based on a known lending rate, such as a bank's prime rate, and is
adjusted automatically each time such rate is adjusted.  The interest rate on a
variable-rate demand obligation is adjusted automatically at specified
intervals.  The issuer of such obligations ordinarily has a right, after a given
period, to prepay in its discretion the outstanding principal amount of the
obligations plus accrued interest upon a specified number of days' notice to the
holders of such obligations.  Frequently, such obligations are secured by
letters of credit or other credit support arrangements provided by banks.

                                       9
<PAGE>

     There generally is no established secondary market for these obligations
because they are direct lending arrangements between the lender and borrower.
Accordingly, where these obligations are not secured by letters of credit or
other credit support arrangements, a Fund's right to redeem is dependent on the
ability of the borrower to pay principal and interest on demand.  Such
obligations frequently are not rated by credit rating agencies and each Fund may
invest in obligations which are not so rated only if the Advisor determines that
at the time of investment the obligations are of comparable quality to the other
obligations in which such Fund may invest. The Advisor, on behalf of each Fund,
considers on an ongoing basis the creditworthiness of the issuers of the
floating- and variable-rate demand obligations in such Fund's portfolio.  No
Fund will invest more than 15% of the value of its total net assets in floating-
or variable-rate demand obligations whose demand feature is not exercisable
within seven days.  Such obligations may be treated as liquid, if an active
secondary market exists.  Floating- and variable-rate instruments are subject to
interest-rate risk and credit risk.

     The floating- and variable-rate instruments that the Funds may purchase
include certificates of participation in such instruments.

     Foreign Investment Risks
     ------------------------

     The Aggressive Balanced-Equity, Growth Balanced and Moderate Balanced Funds
may invest in foreign company stocks which may lose value or be more difficult
to trade as a result of adverse changes in currency exchange rates or other
developments in the issuer's home country.  Concentrated investment in any
single country, especially a less developed country, would make the Fund's value
more sensitive to economic, currency and regulatory changes within that country.
Emerging market countries are often dependent on international trade and are
therefore often vulnerable to events in other countries.  They may have less
developed financial systems and volatile currencies and may be more sensitive
than more mature markets to a variety of economic factors.  Emerging market
securities may also be less liquid than securities of more developed countries,
which may make them more difficult to sell, particularly during a market
downturn.

     Foreign Obligations and Securities
     ----------------------------------

     Each Fund may invest up to 25% of its assets in high-quality, short-term
debt obligations of foreign branches of U.S. banks, U.S. branches of foreign
banks and short-term debt obligations of foreign governmental agencies that are
denominated in and pay interest in U.S. dollars. Investments in foreign
obligations involve certain considerations that are not typically associated
with investing in domestic obligations. There may be less publicly available
information about a foreign issuer than about a domestic issuer and the
available information may be less reliable.  In addition, with respect to
certain foreign countries, taxes may be withheld at the source under foreign tax
laws, and there is a possibility of expropriation or confiscatory taxation,
political or social instability or diplomatic developments that could adversely
affect investments in, the liquidity of, and the ability to enforce contractual
obligations with respect to, securities of issuers located in those countries.
The Funds may invest in securities denominated in currencies other than the U.S.
dollar and may temporarily hold funds in bank deposits or other money market
investments denominated in foreign currencies.  Therefore, the Funds may be
affected favorably or unfavorably by exchange control regulations or changes in
the exchange rate between such currencies and the dollar.  Changes in foreign
currency exchange rates influence values within a

                                       10
<PAGE>

Fund from the perspective of U.S. investors. The rate of exchange between the
U.S. dollar and other currencies is determined by the forces of supply and
demand in the foreign exchange markets. These forces are affected by the
international balance of payments and other economic and financial conditions,
government intervention, speculation and other factors.

     The Funds may enter into forward currency exchange contracts ("forward
contracts") to attempt to minimize the risk to the Funds from adverse changes in
the relationship between currencies or to enhance income [check].  A forward
contract is an obligation to buy or sell a specific currency for an agreed price
at a future date which is individually negotiated and is privately traded by
currency traders and their customers.  The Funds will either cover a position in
such a transaction or maintain, in a segregated account with their custodian
bank, cash or high-grade marketable money market securities having an aggregate
value equal to the amount of any such commitment until payment is made.

     Forward Commitment, When-Issued and Delayed-Delivery Transactions
     -----------------------------------------------------------------

     The Funds may purchase or sell securities on a when-issued or delayed
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time.  Delivery and payment
on such transaction normally take place within 120 days after the date of the
commitment to purchase.  Securities purchased or sold on a when-issued, delayed-
delivery or forward commitment basis involve a risk of loss if the value of the
security to be purchased declines, or the value of the security to be sold
increases, before the settlement date.  The Funds will establish a segregated
account in which they will maintain cash, U.S. Government obligations or other
high-quality debt instruments in an amount at least equal in value to each such
Fund's commitments to purchase when-issued securities. If the value of these
assets declines, a Fund will place additional liquid assets in the account on a
daily basis so that the value of the assets in the account is equal to the
amount of such commitments.

     Futures Contracts
     -----------------

     The LifePath Master Portfolios and the Index Allocation Fund may use
futures contracts as a hedge against the effects of interest rate changes or
changes in the market value of the stocks comprising the index in which such
Master Portfolio invests.  In managing their cash flows, these Master Portfolios
also may use futures contracts as a substitute for holding the designated
securities underlying the futures contract.  A futures contract is an agreement
between two parties, a buyer and a seller, to exchange a particular commodity at
a specific price on a specific date in the future.  At the time it enters into a
futures transaction, a Master Portfolio is required to make a performance
deposit (initial margin) of cash or liquid securities in a segregated account in
the name of the futures broker.  Subsequent payments of "variation margin" are
then made on a daily basis, depending on the value of the futures position which
is continually "marked to market."

     A Master Portfolio may engage only in futures contract transactions
involving (i) the sale of a futures contract (i.e., short positions) to hedge
the value of securities held by such Master Portfolio; (ii) the purchase of a
futures contract when such Master Portfolio hold a short position having the
same delivery month (i.e., a long position offsetting a short position); or
(iii) the purchase of a futures contract to permit the Master Portfolio to, in
effect, participate in the

                                       11
<PAGE>

market for the designated securities underlying the futures contract without
actually owning such designated securities. When a Master Portfolio purchases a
futures contract, it will create a segregated account consisting of cash or
other liquid assets in an amount equal to the total market value of such futures
contract, less the amount of initial margin for the contract.

     If a Master Portfolio enters into a short position in a futures contract as
a hedge against anticipated adverse market movements and the market then rises,
the increase in the value of the hedged securities will be offset, in whole or
in part, by a loss on the futures contract.  If instead a Master Portfolio
purchases a futures contract as a substitute for investing in the designated
underlying securities, a Master Portfolio experiences gains or losses that
correspond generally to gains or losses in the underlying securities.  The
latter type of futures contract transactions permits a Master Portfolio to
experience the results of being fully invested in a particular asset class,
while maintaining the liquidity needed to manage cash flows into or out of the
Master Portfolio (e.g., from purchases and redemptions of Master Portfolio
shares).  Under normal market conditions, futures contract positions may be
closed out on a daily basis.  The LifePath Master Portfolios expect to apply a
portion of their cash or cash equivalents maintained for liquidity needs to such
activities.

     Transactions by a Master Portfolio in futures contracts involve certain
risks.  One risk in employing futures contracts as a hedge against cash market
price volatility is the possibility that futures prices will correlate
imperfectly with the behavior of the prices of the securities in the Master
Portfolio's investment portfolio.  Similarly, in employing futures contracts as
a substitute for purchasing the designated underlying securities, there is a
risk that the performance of the futures contract may correlate imperfectly with
the performance of the direct investments for which the futures contract is a
substitute.  In addition, commodity exchanges generally limit the amount of
fluctuation permitted in futures contract prices during a single trading day,
and the existence of such limits may prevent the prompt liquidation of futures
positions in certain cases.  Limits on price fluctuations are designed to
stabilize prices for the benefit of market participants; however, there could be
cases where the Master Portfolio could incur a larger loss due to the delay in
trading than it would have if no limit rules had been in effect.

     In order to comply with undertakings made by the Master Portfolio pursuant
to Commodity Futures Trading Commission ("CFTC") Regulation 4.5, the Master
Portfolios will use futures and option contracts solely for bona fide hedging
purposes within the meaning and intent of CFTC Reg. 1.3(z); provided, however,
that in addition, with respect to positions in commodity futures or commodity
option contracts which do not come within the meaning and intent of CFTC Reg.
1.3(z), the aggregate initial margin and premiums required to establish such
positions will not exceed five percent of the liquidation value of the Master
Portfolio's portfolio, after taking into account unrealized profits and
unrealized losses on any such contract it has entered into; and provided
further, that in the case of an option that is in-the-money at the time of
purchase, the in-the-money amount as defined in CFTC Reg. 190.01(x) may be
excluded in computing such five percent.

     Future Developments
     -------------------

     Each LifePath Master Portfolio may take advantage of opportunities in the
areas of options and futures contracts and options on futures contracts and any
other derivative

                                       12
<PAGE>

investments which are not presently contemplated for use by such Master
Portfolio or which are not currently available but which may be developed, to
the extent such opportunities are both consistent with a LifePath Master
Portfolio's investment objective and legally permissible for the Master
Portfolio. Before entering into such transactions or making any such investment,
a LifePath Master Portfolio would provide appropriate disclosure in its
Prospectus or this SAI.

     Illiquid Securities
     -------------------

     The Funds may invest in securities not registered under the Securities Act
of 1933, as amended (the "1933 Act") and other securities subject to legal or
other restrictions on resale. Because such securities may be less liquid than
other investments, they may be difficult to sell promptly at an acceptable
price. Delay or difficulty in selling securities may result in a loss or be
costly to a Fund.  Each Fund may invest up to 15% of its net assets in illiquid
securities.

     Loans of Portfolio Securities
     -----------------------------

     Each Fund may lend its portfolio securities to brokers, dealers and
financial institutions, provided: (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at least equal to the
current market value of the securities loaned; (2) such Fund may at any time
call the loan and obtain the return of the securities loaned within five
business days; (3) such Fund will receive any interest or dividends paid on the
loaned securities; and (4) the aggregate market value of securities loaned will
not at any time exceed the limits established by the 1940 Act.

     A Fund will earn income for lending its securities because cash collateral
pursuant to these loans will be invested in short-term money market instruments.
In connection with lending securities, a Fund may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide additional collateral. In either case, a Fund could experience delays
in recovering securities or collateral or could lose all or part of the value of
the loaned securities.  Although voting rights, or rights to consent, attendant
to securities on loan pass to the borrower, such loans may be called at any time
and will be called so that the securities may be voted by a Fund if a material
event affecting the investment is to occur.  A Fund may pay a portion of the
interest or fee earned from securities lending to a borrower or a placing
broker.  Borrowers and placing brokers may not be affiliated, directly or
indirectly with Wells Fargo Bank, Stephens or any of their affiliates.

     Money Market Instruments and Temporary Investments
     --------------------------------------------------

     The Funds, except for the Aggressive Balanced-Equity, Growth Balanced and
Moderate Balanced Funds, may invest in the following types of high quality money
market instruments that have remaining maturities not exceeding one year: (i)
U.S. Government obligations; (ii) negotiable certificates of deposit, bankers'
acceptances and fixed time deposits and other obligations of domestic banks
(including foreign branches) that have more than $1 billion in total assets at
the time of investment and are members of the Federal Reserve System or are
examined by the Comptroller of the Currency or whose deposits are insured by the
FDIC; (iii) commercial paper rated at the date of purchase "Prime-1" by Moody's
or "A-1" or "A-1--" by S&P, or, if unrated, of

                                       13
<PAGE>

comparable quality as determined by BGFA, as investment advisor; and (iv)
repurchase agreements. The Funds also may invest in short-term U.S. dollar-
denominated obligations of foreign banks (including U.S. branches) that at the
time of investment: (i) have more than $10 billion, or the equivalent in other
currencies, in total assets; (ii) are among the 75 largest foreign banks in the
world as determined on the basis of assets; (iii) have branches or agencies in
the United States; and (iv) in the opinion of BGFA, as investment advisor, are
of comparable quality to obligations of U.S. banks which may be purchased by the
Funds.

     Mortgage-Related Securities
     ---------------------------

     The Funds, except the Index Allocation Fund, may invest in mortgage-related
securities.  Mortgage pass-through securities are securities representing
interests in "pools" of mortgages in which payments of both interest and
principal on the securities are made monthly, in effect "passing through"
monthly payments made by the individual borrowers on the residential mortgage
loans which underlie the securities (net of fees paid to the issuer or guarantor
of the securities).  Payment of principal and interest on some mortgage pass-
through securities (but not the market value of the securities themselves) may
be guaranteed by the full faith and credit of the U.S. Government or its
agencies or instrumentalities.  Mortgage pass-through securities created by non-
government issuers (such as commercial banks, savings and loan institutions,
private mortgage insurance companies, mortgage bankers and other secondary
market issuers) may be supported by various forms of insurance or guarantees,
including individual loan, title, pool and hazard insurance, and letters of
credit, which may be issued by governmental entities, private insurers or the
mortgage poolers.

     Prepayment Risk.  The stated maturities of mortgage-related securities may
be shortened by unscheduled prepayments of principal on the underlying
mortgages.  Therefore, it is not possible to predict accurately the average
maturity of a particular mortgage-related security .  Variations in the
maturities of mortgage-related securities will affect the yield of the Fund.
Early repayment of principal on mortgage-related securities may expose a Fund to
a lower rate of return upon reinvestment of principal. Also, if a security
subject to prepayment has been purchased at a premium, in the event of
prepayment the value of the premium would be lost. Like other fixed-income
securities, when interest rates rise, the value of a mortgage-related security
generally will decline; however, when interest rates decline, the value of
mortgage-related securities with prepayment features may not increase as much as
other fixed-income securities.

     Collateralized Mortgage Obligations ("CMOs") and Adjustable Rate Mortgages
("ARMs").  The Funds may also invest in investment grade CMOs.  CMOs may be
collateralized by whole mortgage loans but are more typically collateralized by
portfolios of mortgage pass-through securities guaranteed by the Government
National Mortgage Association ("GNMA"), the Federal Home Loan Mortgage
Corporation ("FHLMC") or Federal National Mortgage Association ("FNMA"). CMOs
are structured into multiple classes, with each class bearing a different stated
maturity. Payments of principal, including prepayments, are first returned to
investors holding the shortest maturity class; investors holding the longer
maturity classes receive principal only after the first class has been retired.
As new types of mortgage-related securities are developed and offered to
investors, the Advisor will, consistent with the Fund's investment objective,
policies and quality standards, consider making investments in such new types of
mortgage-related securities.

                                       14
<PAGE>

     The Funds each may invest in ARMs issued or guaranteed by the GNMA, FNMA or
the FHLMC. The full and timely payment of principal and interest on GNMA ARMs is
guaranteed by GNMA and backed by the full faith and credit of the U.S.
Government. FNMA also guarantees full and timely payment of both interest and
principal, while FHLMC guarantees full and timely payment of interest and
ultimate payment of principal. FNMA and FHLMC ARMs are not backed by the full
faith and credit of the United States. However, because FNMA and FHLMC are
government-sponsored enterprises, these securities are generally considered to
be high quality investments that present minimal credit risks. The yields
provided by these ARMs have historically exceeded the yields on other types of
U.S. Government securities with comparable maturities, although there can be no
assurance that this historical performance will continue.

     The mortgages underlying ARMs guaranteed by GNMA are typically insured or
guaranteed by the Federal Housing Administration, the Veterans Administration or
the Farmers Home Administration, while those underlying ARMs issued by FNMA or
FHLMC are typically conventional residential mortgages which are not so insured
or guaranteed, but which conform to specific underwriting, size and maturity
standards.

     The interest rates on the mortgages underlying the ARMs and some of the
CMOs in which the Funds may invest generally are readjusted at periodic
intervals ranging from one year or less to several years in response to changes
in a predetermined commonly-recognized interest rate index. The adjustable rate
feature should reduce, but will not eliminate, price fluctuations in such
securities, particularly when market interest rates fluctuate. The net asset
value of a Funds' shares may fluctuate to the extent interest rates on
underlying mortgages differ from prevailing market interest rates during interim
periods between interest rate reset dates. Accordingly, investors could
experience some loss if they redeem their shares of a Fund or if the Funds sells
these portfolio securities before the interest rates on the underlying mortgages
are adjusted to reflect prevailing market interest rates. The holder of ARMs and
CMOs are also subject to repayment risk.

     The Funds will not invest in CMOs that, at the time of purchase, are "high-
risk mortgage securities" as defined in the then current Federal Financial
Institutions Examination Council Supervisory Policy Statement on Securities
Activities. High-risk mortgage securities are generally those with long
durations or those which are likely to be more sensitive to interest-rate
fluctuations.

     Mortgage Participation Certificates. The Short-Intermediate U.S. Government
Income Fund and Intermediate Government Income Fund also may invest in the
following types of FHLMC mortgage pass-through securities. FHLMC issues two
types of mortgage pass-through securities: mortgage participation certificates
("PCs") and guaranteed mortgage certificates ("GMCs"). PCs resemble GNMA
certificates in that each PC represents a pro rata share of all interest and
principal payments made and owed on the underlying pool of mortgages. GMCs also
represent a pro rata interest in a pool of mortgages. These instruments,
however, pay interest semiannually and return principal once a year in
guaranteed minimum payments. These mortgage pass-through securities differ from
bonds in that principal is paid back by the borrower over the length of the loan
rather than returned in a lump sum at maturity. They are called "pass-through"
securities because both interest and principal payments, including prepayments,
are passed through to the holder of the security. PCs and GMCs are both subject
to prepayment risk.

     Options Trading
     ---------------

     The Funds, except the Index Allocation Fund, may purchase or sell options
on individual securities or options on indices of securities as described below.
The purchaser of an option risks a total loss of the premium paid for the option
if the price of the underlying security does not increase or decrease
sufficiently to justify exercise. The seller of an option, on the other hand,
will recognize the premium as income if the option expires unrecognized but
foregoes any capital appreciation in excess of the exercise price in the case of
a call option and may be required to pay a price in excess of current market
value in the case of a put option.

     Call and Put Options on Specific Securities. The Funds may invest in call
and put options on a specific security. A call option gives the purchaser of the
option the right to buy, and obligates the writer to sell, an underlying
security at the exercise price at any time during the option period. Conversely,
a put option gives the purchaser of the option the right to sell, and obligates
the writer to buy, an underlying security at the exercise price at any time
during the option period. Investments by a Fund in off-exchange options will be
treated as "illiquid" and therefore subject to the Fund's policy of not
investing more than 15% of its net assets in illiquid securities.

     The Funds may write covered call option contracts and secured put options
as BGFA deems appropriate. A covered call option is a call option for which the
writer of the option owns the security covered by the option. Covered call
options written by a Fund expose the Fund during the term of the option (i) to
the possible loss of opportunity to realize appreciation in the market price of
the underlying security or (ii) to possible loss caused by continued holding of
a security which might otherwise have been sold to protect against depreciation
in the market price of the security. If a Fund writes a secured put option, it
assumes the risk of loss should the market value of the underlying security
decline below the exercise price of the option. The aggregate value of the
securities subject to options written by a Fund will not exceed 25%. The use of
covered call options and securities put options will not be a primary investment
technique of the Funds, and they are expected to be used infrequently. If the
advisor is incorrect in its forecast of market value or other factors when
writing the foregoing options, a Fund would be in a worse position than it would
have been had the foregoing investment techniques not been used.

     Each Fund may engage in unlisted over-the-counter options with
broker/dealers deemed creditworthy by the advisor. Closing transactions for such
options are usually effected directly with the same broker/dealer that effected
the original option transaction. A Fund bears the risk that the broker/dealer
will fail to meet its obligations. There is no assurance that a liquid secondary
trading market exists for closing out an unlisted option position. Furthermore,
unlisted options are not subject to the protections afforded purchasers of
listed options by the Options Clearing Corporation, which performs the
obligations of its members who fail to perform in connection with the purchase
or sale of options.

     Each Fund may buy put and call options and write covered call and secured
put options. Options trading is a highly specialized activity which entails
greater than ordinary investment risk. Options may be more volatile than the
underlying instruments, and therefore, on a percentage basis, an investment in
options may be subject to greater fluctuation than an investment in the
underlying instruments themselves. Purchasing options is a specialized
investment technique that

                                       16
<PAGE>

entails a substantial risk of a complete loss of the amounts paid as premiums to
the writer of the option.

     The Funds may also write covered call and secured put options from time to
time as the advisor deems appropriate. By writing a covered call option, a Fund
forgoes the opportunity to profit from an increase in the market of the
underlying security above the exercise price except insofar as the premium
represents such a profit, and it is not able to sell the underlying security
until the option expires or is exercised or the Fund effects a closing purchase
transaction by purchasing an option of the same series. If a Fund writes a
secured put option, it assumes the risk of loss should the market value of the
underlying security decline below the exercise price of the option. If the
advisor is incorrect in its forecast of market value or other factors when
writing the foregoing options, the Fund would be in a worse position than it
would have been had the foregoing investment techniques not been used.

     A call option for a particular security gives the purchaser of the option
the right to buy, and a writer the obligation to sell, the underlying security
at the stated exercise price at any time prior to the expiration of the option,
regardless of the market price of the security. The premium paid to the writer
is in consideration for undertaking the obligation under the option contract. A
put option for a particular security gives the purchaser the right to sell the
security at the stated exercise price at any time prior to the expiration date
of the option, regardless of the market price of the security. Options on
indices provide the holder with the right to make or receive a cash settlement
upon exercise of the option. With respect to options on indices, the amount of
the settlement equals the difference between the closing price of the index at
the time of exercise and the exercise price of the option expressed in dollars,
times a specified multiple.

     The Funds will write call options only if they are "covered." In the case
of a call option on a security or currency, the option is "covered" if a Fund
owns the instrument underlying the call or has an absolute and immediate right
to acquire that instrument without additional cash consideration (or, if
additional cash consideration is required, cash, U.S. Government securities or
other liquid high grade debt obligations, in such amount are held in a
segregated account by the Fund's custodian) upon conversion or exchange of other
securities held by it. For a call option on an index, the option is covered if a
Fund maintains with its custodian a diversified portfolio of securities
comprising the index or liquid assets equal to the contract value. A call option
is also covered if a Fund holds a call on the same instrument or index as the
call written where the exercise price of the call held is (i) equal to or less
than the exercise price of the call written, or (ii) greater than the exercise
price of the call written provided the difference is maintained by the Fund in
liquid assets in a segregated account with its custodian. The Funds will write
put options only if they are "secured" by liquid assets maintained in a
segregated account by the Funds' custodian in an amount not less than the
exercise price of the option at all times during the option period.

     A Fund's obligation to sell an instrument subject to a covered call option
written by it, or to purchase an instrument subject to a secured put option
written by it, may be terminated prior to the expiration date of the option by
the Fund's execution of a closing purchase transaction, which is effected by
purchasing on an exchange an option of the same series (i.e., same underlying
instrument, exercise price and expiration date) as the option previously
written. Such a purchase does not result in the ownership of an option. A
closing purchase transaction is ordinarily effected to realize a profit on an
outstanding option, to prevent an underlying instrument from being called,

                                       17
<PAGE>

to permit the sale of the underlying instrument or to permit the writing of a
new option containing different terms on such underlying instrument. The cost of
such a liquidation purchase plus transaction costs may be greater than the
premium received upon the original option, in which event the Fund will have
incurred a loss in the transaction. There is no assurance that a liquid
secondary market will exist for any particular option. An option writer, unable
to effect a closing purchase transaction, will not be able to sell the
underlying instrument (in the case of a covered call option) or liquidate the
segregated account (in the case of a secured put option) until the option
expires or the optioned instrument or currency is delivered upon exercise with
the result that the writer in such circumstances will be subject to the risk of
market decline or appreciation in the instrument during such period.

     When a Fund purchases an option, the premium paid by it is recorded as an
asset of the Fund. When a Fund writes an option, an amount equal to the net
premium (the premium less the commission) received by a Fund is included in the
liability section of the Fund's statement of assets and liabilities as a
deferred credit. The amount of this asset or deferred credit will be
subsequently marked-to-market to reflect the current value of the option
purchased or written. The current value of the traded option is the last sale
price or, in the absence of a sale, the current bid price. If an option
purchased by a Fund expires unexercised the Fund realizes a loss equal to the
premium paid. If a Fund enters into a closing sale transaction on an option
purchased by it, the Fund realizes a gain if the premium received by the Fund on
the closing transaction is more than the premium paid to purchase the option, or
a loss if it is less. If an option written by a Fund expires on the stipulated
expiration date or if a Fund enters into a closing purchase transaction, it
realizes a gain (or loss if the cost of a closing purchase transaction exceeds
the net premium received when the option is sold) and the deferred credit
related to such option is eliminated. If an option written by a Fund is
exercised, the proceeds of the sale are increased by the net premium originally
received and the Fund realizes a gain or loss.

     There are several risks associated with transactions in options. For
example, there are significant differences between the securities, currency and
options markets that could result in an imperfect correlation between these
markets, causing a given transaction not to achieve its objectives. In addition,
a liquid secondary market for particular options, whether traded over-the-
counter or on an exchange, may be absent for reasons that include the following:
there may be insufficient trading interest in certain options; restrictions may
be imposed by an exchange on opening transactions or closing transactions or
both; trading halts, suspensions or other restrictions may be imposed with
respect to particular classes or series of options or underlying securities or
currencies; unusual or unforeseen circumstances may interrupt normal operations
on an exchange; the facilities of an exchange or the Options Clearing
Corporation may not be adequate at all times  to handle current trading value;
or one or more exchanges could, for economic or other reasons, decide or be
compelled at some future date to discontinue the trading of options (or a
particular class or series of options), in which event the secondary market on
that exchange (or in that class or series of options) would cease to exist,
although outstanding options that had been issued by the Options Clearing
Corporation as a result of trades on that exchange would continue to be
exercisable in accordance with their terms. A Fund is likely to be unable to
control losses by closing its position where a liquid secondary market does not
exist. A decision as to whether, when and how to use options involves the
exercise of skill and judgment, and even a well-conceived transaction may be
unsuccessful to some degree because of market behavior or unexpected events.

                                       18
<PAGE>

     The Funds may purchase or sell options on individual securities or options
on indices of securities as described below. The purchaser of an option risks a
total loss of the premium paid for the option if the price of the underlying
security does not increase or decrease sufficiently to justify exercise. The
seller of an option, on the other hand, will recognize the premium as income if
the option expires unrecognized but foregoes any capital appreciation in excess
of the exercise price in the case of a call option and may be required to pay a
price in excess of current market value in the case of a put option.

     The Funds may engage in unlisted over-the-counter options with
broker/dealers deemed creditworthy by the advisor. Closing transactions for such
options are usually effected directly with the same broker/dealer that effected
the original option transaction. A Fund bears the risk that the broker/dealer
will fail to meet its obligations. There is no assurance that a liquid secondary
trading market exists for closing out an unlisted option position. Furthermore,
unlisted options are not subject to the protections afforded purchasers of
listed options by the Options Clearing Corporation, which performs the
obligations of its members who fail to perform in connection with the purchase
or sale of options.

     Stock Index Options.  The Funds may purchase call and put options and write
covered call options on stock indices listed on national securities exchanges or
traded in the over-the-counter market to the extent of 25% of the value of its
net assets.

     The effectiveness of purchasing or writing stock index options will depend
upon the extent to which price movements in a Fund's investment portfolio
correlate with price movements of the stock index selected. Because the value of
a stock index option depends upon changes to the price of all stocks comprising
the index rather than the price of a particular stock, whether a Fund will
realize a gain or loss from the purchase or writing of options on an index
depends upon movements in the price of all stocks in the index, rather than
movements in the price of a particular stock. Accordingly, successful use by a
Fund of options on stock indexes will be subject to BGFA's ability to correctly
analyze movements in the direction of the stock market generally or of
particular industry or market segments.

     Stock Index Futures Contracts and Options on Stock Index Futures Contracts.
The Funds may participate in stock index futures contracts and options on stock
index futures contracts. A futures transaction involves a firm agreement to buy
or sell a commodity or financial instrument at a particular price on a specified
future date, while an option transaction generally involves a right, which may
or may not be exercised, to buy or sell a commodity of financial instrument at a
particular price on a specified future date. Futures contracts and options are
standardized and exchange-traded, where the exchange serves as the ultimate
counterparty for all contracts. Consequently, the only credit risk on futures
contracts is the creditworthiness of the exchange. Futures contracts, however,
are subject to market risk (i.e., exposure to adverse price changes).

     A stock index futures contract is an agreement in which one party agrees to
deliver to the other an amount of cash equal to a specific dollar amount
multiplied by the difference between the value of a specific stock index at the
close of the last trading day of the contract and the price at which the
agreement is made. As the aggregate market value of the stocks in the index
changes, the value of the index also changes. In the event that the index level
rises above the level at which the stock index futures contract was sold, the
seller of the stock index futures contract realizes a loss

                                       19
<PAGE>

determined by the difference between the two index levels at the time of
expiration of the stock index futures contract, and the purchaser realizes a
gain in that amount. In the event the index level falls below the level at which
the stock index futures contract was sold, the seller recognizes a gain
determined by the difference between the two index levels at the expiration of
the stock index futures contract, and the purchaser realizes a loss. Stock index
futures contracts expire on a fixed date, currently one to seven months from the
date of the contract, and are settled upon expiration of the contract.

     Stock index futures contracts may be purchased to protect a Fund against an
increase in the prices of stocks that Fund intends to purchase. If a Fund is
unable to invest its cash (or cash equivalents) in stock in an orderly fashion,
a Fund may purchase a stock index futures contract to offset any increase in the
price of the stock. However, it is possible that the market may decline instead,
resulting in a loss on the stock index futures contract. If Fund then concludes
not to invest in stock at that time, or if the price of the securities to be
purchased remains constant or increases, a Fund realizes a loss on the stock
index futures contract that is not offset by a reduction in the price of
securities purchased. The Funds also may buy or sell stock index futures
contracts to close out existing futures positions.

     The Funds may also purchase put options on stock index futures contracts.
Sales of such options may also be made to close out an open option position. The
Funds may, for example, purchase a put option on a particular stock index
futures contract or stock index to protect against a decline in the value of the
common stocks it holds. If the stocks in the index decline in value, the put
should become more valuable and the Funds could sell it to offset losses in the
value of the common stocks. In this way, put options may be used to achieve the
same goals the Funds seek in selling futures contracts. A put option on a stock
index future gives the purchaser the right, in return for a premium paid, to
assume a short (i.e., the right to sell stock index futures) position in a stock
index futures contract at a specified exercise price ("strike price") at any
time during the period of the option. If the option is exercised by the holder
before the last trading date during the option period, the holder receives the
futures position, as well as any balance in the futures margin account. If an
option is exercised on the last trading day prior to the expiration date of the
option, the settlement is made entirely in cash in an amount equal to the
difference between the strike price and the closing level of the relevant index
on the expiration date.

     BGFA expects that an increase or decrease in the index in relation to the
strike price level would normally correlate to an increase or decrease (but not
necessarily to the same extent) in the value of a Fund's common stock portfolio
against which the option was written. Thus, any loss in the option transaction
may be offset by an increase in the value of the common stock portfolio to the
extent changes in the index correlate to changes in the value of that portfolio.
The Funds may liquidate the put options they have purchased by effecting a
closing sale transaction rather than exercising the option. This is accomplished
by selling an option of the same series as the option previously purchased.
There is no guarantee that the Funds will be able to effect the closing sale
transaction. The Funds realize a gain from a closing sale transaction if the
price at which the transaction is effected exceeds the premium paid to purchase
the option and, if less, the Funds  realize a loss.

     The Funds may each invest in stock index futures in order to protect the
value of common stock investments or to maintain liquidity, provided not more
than 5% of a Fund's net assets are

                                       20
<PAGE>

committed to such transactions. A stock index future obligates the seller to
deliver (and the purchaser to take), effectively, an amount of cash equal to a
specific dollar amount times the difference between the value of a specific
stock index at the close of the last trading day of the contract and the price
at which the agreement is made. No physical delivery of the underlying stocks in
the index is made. With respect to stock indices that are permitted investments,
the Funds intend to purchase and sell futures contracts on the stock index for
which it can obtain the best price with consideration also given to liquidity.
There can be no assurance that a liquid market will exist at the time when a
Fund seeks to close out a futures contract or a futures option position. Lack of
a liquid market may prevent liquidation of an unfavorable position.

     Other Investment Companies
     --------------------------

     The Funds except the Aggressive Balanced-Equity, Growth Balanced and the
Moderate Balanced Funds, may invest in shares of other open-end management
investment companies, up to the limits prescribed in Section 12(d) of the 1940
Act.  Under the 1940 Act, a Fund's investment in such securities currently is
limited to, subject to certain exceptions, (i) 3% of the total voting stock of
any one investment company, (ii) 5% of such Fund's net assets with respect to
any one investment company and (iii) 10% of such Fund's net assets in aggregate.
Other investment companies in which the Funds invest can be expected to charge
fees for operating expenses, such as investment advisory and administration
fees, that would be in addition to those charged by the Funds.

     Pass-Through Obligations
     ------------------------

     The Index Allocation Fund may invest in pass-through obligations that are
supported by the full faith and credit of the U.S. Government (such as those
issued by the Government National Mortgage Association ("GNMA")) or those that
are guaranteed by an agency or instrumentality of the U.S. Government or
government-sponsored enterprise (such as the Federal National Mortgage
Association ("FNMA") or the Federal Home Loan Mortgage Corporation ("FHLMC")) or
bonds collateralized by any of the foregoing.

     Privately Issued Securities
     ---------------------------

     The LifePath Funds may invest in privately issued securities, including
those which may be resold only in accordance with Rule 144A under the Securities
Act of 1933 ("Rule 144A Securities"). Rule 144A Securities are restricted
securities that are not publicly traded. Accordingly, the liquidity of the
market for specific Rule 144A Securities may vary. Delay or difficulty in
selling such securities may result in a loss to a Fund. Privately issued or Rule
144A securities that are determined by the investment advisor to be "illiquid"
are subject to the Funds' policy of not investing more than 15% of its net
assets in illiquid securities.  The investment advisor, under guidelines
approved by Board of Trustees of the Company, will evaluate the liquidity
characteristics of each Rule 144A Security proposed for purchase by a Fund on a
case-by-case basis and will consider the following factors, among others, in
their evaluation: (1) the frequency of trades and quotes for the Rule 144A
Security; (2) the number of dealers willing to purchase or sell the Rule 144A
Security and the number of other potential purchasers; (3) dealer undertakings
to make a market in the Rule 144A Security; and (4) the nature of the Rule 144A

                                       21
<PAGE>

Security and the nature of the marketplace trades (e.g., the time needed to
dispose of the Rule 144A Security, the method of soliciting offers and the
mechanics of transfer).

     Repurchase Agreements.  Each Fund may enter into repurchase agreements,
     ---------------------
wherein the seller of a security to a Fund agrees to repurchase that security
from a Fund at a mutually agreed upon time and price. A Fund may enter into
repurchase agreements only with respect to securities that could otherwise be
purchased by such Fund. All repurchase agreements will be fully collateralized
at 102% based on values that are marked to market daily. The maturities of the
underlying securities in a repurchase agreement transaction may be greater than
twelve months, although the maximum term of a repurchase agreement will always
be less than twelve months. If the seller defaults and the value of the
underlying securities has declined, a Fund may incur a loss. In addition, if
bankruptcy proceedings are commenced with respect to the seller of the security,
the Funds' disposition of the security may be delayed or limited.

     A Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 15% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities. A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Trustees and that are not affiliated with the investment advisor. The
Funds may participate in pooled repurchase agreement transactions with other
funds advised by Wells Fargo Bank.

     Short-Term Corporate Debt Instruments
     -------------------------------------

     The Index Allocation Fund may invest in commercial paper (including
variable amount master demand notes), which refers to short-term, unsecured
promissory notes issued by corporations to finance short-term credit needs.
Commercial paper is usually sold on a discount basis and has a maturity at the
time of issuance not exceeding nine months. Variable amount master demand notes
are demand obligations that permit the investment of fluctuating amounts at
varying market rates of interest pursuant to arrangements between the issuer and
a commercial bank acting as agent for the payee of such notes whereby both
parties have the right to vary the amount of the outstanding indebtedness on the
notes.

     The Funds also may invest in nonconvertible corporate debt securities
(e.g., bonds and debentures) with no more than one year remaining to maturity at
the date of settlement. The Funds will invest only in such corporate bonds and
debentures that are rated at the time of purchase at least "Aa" by Moody's or
"AA" by S&P.

     Stripped Securities
     -------------------

     The Funds except the LifePath and Index Allocation Funds, may purchase
Treasury receipts, securities of government-sponsored enterprises (GSEs), and
other "stripped" securities that evidence ownership in either the future
interest payments or the future principal payments on U.S. Government and other
obligations. The stripped securities the Funds may purchase are issued by the
U.S. Government (or a U.S. Government agency or instrumentality) or by private
issuers such as banks, corporations and other institutions at a discount to
their face value. The Funds will not purchase stripped mortgage-backed
securities ("SMBS"). The stripped securities purchased by

                                       22
<PAGE>

the Funds generally are structured to make a lump-sum payment at maturity and do
not make periodic payments of principal or interest. Hence, the duration of
these securities tends to be longer and they are therefore more sensitive to
interest rate fluctuations than similar securities that offer periodic payments
over time. The stripped securities purchased by the Funds are not subject to
prepayment or extension risk.

     The Funds may purchase participations in trusts that hold U.S. Treasury
securities (such as TIGRs and CATS) or other obligations where the trust
participations evidence ownership in either the future interest payments or the
future principal payments on the obligations. These participations are normally
issued at a discount to their "face value," and can exhibit greater price
volatility than ordinary debt securities because of the way in which their
principal and interest are returned to investors. Investments by the Funds in
such participations will not exceed 5% of the value of the Funds' total assets.

     Reverse Repurchase Agreements
     -----------------------------

     The Funds intend to limit their borrowings (including reverse repurchase
agreements) during the current fiscal year to not more than 10% of net assets.
At the time a Fund enters into a reverse repurchase agreement (an agreement
under which a Fund sells their portfolio securities and agrees to repurchase
them at an agreed-upon date and price), it will place in a segregated custodial
account liquid assets such as U.S. Government securities or other liquid high-
grade debt securities having a value equal to or greater than the repurchase
price (including accrued interest) and will subsequently monitor the account to
ensure that such value is maintained. Reverse repurchase agreements involve the
risk that the market value of the securities sold by the Funds may decline below
the price at which the Funds are obligated to repurchase the securities. Reverse
repurchase agreements are considered to be borrowings under the 1940 Act.

     Unrated Investments
     -------------------

     The Index Allocation Fund, may purchase instruments that are not rated if,
in the opinion of Wells Fargo Bank, such obligations are of investment quality
comparable to other rated investments that are permitted to be purchased by such
Fund. After purchase by a Fund, a security may cease to be rated or its rating
may be reduced below the minimum required for purchase by such Fund. Neither
event will require a sale of such security by such Fund. To the extent the
ratings given by Moody's or S&P may change as a result of changes in such
organizations or their rating systems, each Fund will attempt to use comparable
ratings as standards for investments in accordance with the investment policies
contained in its Prospectus and in this SAI. The ratings of Moody's and S&P are
more fully described in the Appendix.

     U.S. Government Obligations
     ---------------------------

     The Funds may invest in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Obligations").
Payment of principal and interest on U.S. Government Obligations (i) may be
backed by the full faith and credit of the United States (as with U.S. Treasury
bills and GNMA certificates) or (ii) may be backed solely by the issuing or
guaranteeing agency or instrumentality itself (as with FNMA notes). In the
latter case investors must look principally to the agency or instrumentality
issuing or guaranteeing the obligation for

                                       23
<PAGE>

ultimate repayment, which agency or instrumentality may be privately owned.
There can be no assurance that the U.S. Government will provide financial
support to its agencies or instrumentalities where it is not obligated to do so.
In addition, U.S. Government Obligations are subject to fluctuations in market
value due to fluctuations in market interest rates. As a general matter, the
value of debt instruments, including U.S. Government Obligations, declines when
market interest rates increase and rises when market interest rates decrease.
Certain types of U.S. Government Obligations are subject to fluctuations in
yield or value due to their structure or contract terms.

     Warrants
     --------

     The Funds except the Aggressive Balanced-Equity, Growth Balanced and
Moderate Balanced Funds, each may invest in warrants (other than those that have
been acquired in units or attached to other securities). Warrants represent
rights to purchase securities at a specific price valid for a specific period of
time. The price of warrants do not necessarily correlate with the prices of the
underlying securities.

     Zero Coupon Bonds
     -----------------

     The Aggressive Balanced-Equity, Growth Balanced and Moderate Balanced Funds
may invest in zero coupon bonds. Zero coupon bonds are securities that make no
periodic interest payments, but are instead sold at discounts from face value.
The buyer of such a bond receives the rate of return by the gradual appreciation
of the security, which is redeemed at face value on a specified maturity date.
Because zero coupon bonds bear no interest, they are more sensitive to interest-
rate changes and are therefore more volatile. When interest rates rise, the
discount to face value of the security deepens and the securities decrease more
rapidly in value, when interest rates fall, zero coupon securities rise more
rapidly in value because the bonds carry fixed interest rates that become more
attractive in a falling interest rate environment.

     Nationally Recognized Ratings Organizations
     -------------------------------------------

     The ratings of Moody's, S&P, Division of McGraw Hill, Duff & Phelps Credit
Rating Co., Fitch Investors Service, Inc. Thomson Bank Watch and IBCA Inc.
represent their opinions as to the quality of debt securities. It should be
emphasized, however, that ratings are general and not absolute standards of
quality, and debt securities with the same maturity, interest rate and rating
may have different yields while debt securities of the same maturity and
interest rate with different ratings may have the same yield. Subsequent to
purchase by the Funds, an issue of debt securities may cease to be rated or its
rating may be reduced below the minimum rating required for purchase by the
Funds. The Advisor will consider such an event in determining whether the Fund
involved should continue to hold the obligation.

     Each of the Trustees and Officers listed above, act in the identical
capacities for Wells Fargo Variable Trust and Wells Fargo Core Trust
(collectively the "Fund Complex"). Trustees are compensated annually by the
Trust and by all the registrants in each fund complex they serve beginning
September 17, 1999, and beginning March 26, 1999, receive a per-meeting fee of
$250. Trustees also are reimbursed for all out-of-pocket expenses relating to
attendance at board meetings. Each of the Trustees and Officers of the Trust
serves in the identical capacity as trustees and/or officers of each registered
open-end management investment company in the Fund Complex. The Trustees are
compensated by other companies and trusts within a fund complex for their
services as directors/trustees to such companies and trusts. Currently the
Trustees do not receive any retirement benefits or deferred compensation from
the Trust or any other member of each fund complex.

     Master/Feeder Structure.  Each LifePath Fund seeks to achieve its
     -----------------------
investment objective by investing all of its assets in a corresponding LifePath
Master Portfolio of MIP.  The LifePath Opportunity Fund invests its assets in
the LifePath 2000 Master Portfolio.  The Funds and other entities investing in a
Master Portfolio are each liable for all obligations of the Master Portfolio.
However, the risk of a Fund incurring financial loss on account of such
liability is limited to circumstances in which both inadequate insurance existed
and MIP itself is unable to meet its obligations. Accordingly, the Company's
Board of Trustees believes that neither a Fund nor its shareholders will be
adversely affected by investing Fund assets in the Master Portfolio. However, if
a mutual fund or other investor withdraws its investment from the Master
Portfolio, the economic efficiencies (e.g., spreading fixed expenses among a
larger asset base) that the Board believes may be available through investment
in the Master Portfolio may not be fully achieved. In addition, given the
relative novelty of the master/feeder structure, accounting or operational
difficulties, although unlikely, could arise. See "Organization and Management
of the Funds" in the Prospectus for additional description of the Funds' and
Master Portfolios' expenses and management.

     Each Fund may withdraw its investment in the corresponding Master Portfolio
only if the Company's Board of Trustees determines that such action is in the
best interests of such Fund and its shareholders. Upon such withdrawal, the
Board would consider alternative investments, including investing all of the
Fund's assets in another investment company with the same investment objective
as the Fund or hiring an investment advisor to manage the Fund's assets in
accordance with the investment policies described below with respect to the
Master Portfolio.

     The investment objective and other fundamental policies of a Master
Portfolio cannot be changed without approval by the holders of a majority (as
defined in the 1940 Act) of the Master Portfolio's outstanding interests. See
"Investment Objectives" and "Investment Policies" in the Prospectus. Whenever a
Fund, as an interestholder of a Master Portfolio, is requested to vote on any
matter submitted to interestholders of the Master Portfolio, the Fund will hold
a meeting of its shareholders to consider such matters. The Fund will cast its
votes in proportion to the votes received from its shareholders. Shares for
which the Fund receives no voting instructions will be voted in the same
proportion as the votes received from the other Fund shareholders.

     Certain policies of a Master Portfolio which are non-fundamental may be
changed by vote of a majority of MIP's Trustees without interestholder approval.
If a Master Portfolio's investment objective or fundamental or non-fundamental
policies are changed, the corresponding Fund may elect to change its objective
or policies to correspond to those of the Master Portfolio.  The Fund may also
elect to redeem its interests in the Master Portfolio and either seek a new
investment company with a matching objective in which to invest or retain its
own investment advisor to manage the Fund's portfolio in accordance with its
objective. In the latter case, a Fund's inability to find a substitute
investment company in which to invest or equivalent management services could
adversely affect shareholders' investments in the Fund. Each Fund will provide
shareholders with 30 days' written notice prior to the implementation of any
change in the investment objective of the Fund or the Master Portfolio, to the
extent possible.

     Investment Advisor.  Wells Fargo Bank provides portfolio management and
     ------------------
fundamental security analysis services as the advisor for the Funds. Wells Fargo
Bank, founded in 1852, is the oldest bank in the western United States and is
one of the largest banks in the United States. Wells Fargo Bank is a wholly
owned subsidiary of Wells Fargo & Company, a national bank holding company. As
of December 31, 1998, Wells Fargo Bank and its affiliates managed over $202
billion in assets.

     For providing investment advisory services to the Index Allocation Fund,
Wells Fargo is entitled to receive a fee of .80% of the Fund's average annual
net assets. The Aggressive Balanced-Equity, Growth Balanced and Moderate
Balanced Funds are gateway Funds that invest in various core portfolios. Wells
Fargo Bank is entitled to receive an investment advisory fee of .25% of each
Fund's average annual net assets for providing advisory services, including the
determination of the asset allocations of each Fund's investments in the core
portfolios. Wells Fargo Bank also acts as the Advisor to the core portfolios and
is entitled to receive a fee from each core portfolio. The total amount of
investment advisory fees paid to Wells Fargo Bank as a result of a Fund's
investments varies depending on the Fund's allocation of assets among the
various core portfolios. The chart below lists the advisory fees charged at the
core level for each core portfolio in which the Funds invest.

     Administrator.  The Trust has retained Wells Fargo Bank as Administrator on
     -------------
behalf of each Fund.  Under the Administration Agreement between Wells Fargo
Bank and the Trust, Wells Fargo Bank shall provide as administration services,
among other things:  (i) general supervision of the Funds' operations, including
coordination of the services performed by each Fund's investment Advisor,
transfer agent, custodian, shareholder servicing agent(s), independent auditors
and legal counsel, regulatory compliance, including the compilation of
information for documents such as reports to, and filings with, the U.S.
Securities and Exchange Commission ("SEC") and state securities commissions; and
preparation of proxy statements and shareholder reports for each Fund; and (ii)
general supervision relative to the compilation of data required for the
preparation of periodic reports distributed to the Trust's officers and Board of
Trustees.  Wells Fargo Bank also furnish office space and certain facilities
required for conducting the Funds' business together with ordinary clerical and
bookkeeping services.  The Administrator is entitled to receive a fee of 0.15%
of average daily net assets on an annual basis.

     Distributor.  Stephens (the "Distributor"), located at 111 Center Street,
     -----------
Little Rock, Arkansas  72201, serves as the Distributor for the Funds.  Each
Fund has adopted a distribution plan (a "Plan") under Section 12(b) of the 1940
Act and Rule 12b-1 thereunder (the "Rule") for

                                       31
<PAGE>

its Class B and Class C shares. The Plan was adopted by the Trust's Board of
Trustees, including a majority of the Trustees who were not "interested persons"
(as defined in the 1940 Act) of the Funds and who had no direct or indirect
financial interest in the operation of the Plan or in any agreement related to
the Plan (the "Non-Interested Trustees").

     Under the Plan and pursuant to the related Distribution Agreement, the
Funds may pay Stephens up to 0.75% of the average daily net assets attributable
to the Class B and Class C shares of the Funds as compensation for distribution-
related services or as reimbursement for distribution-related expenses.  In
addition, the LifePath Fund may pay Stephens up to 0.25% of the average daily
net assets attributable to each Funds Class A shares.

     The actual fee payable to the Distributor is determined, within such
limits, from time to time by mutual agreement between the Trust and the
Distributor and will not exceed the maximum sales charges payable by mutual
funds sold by members of the National Association of Securities Dealers, Inc.
("NASD") under the Conduct Rules of the NASD. The Distributor may enter into
selling agreements with one or more selling agents (which may include Wells
Fargo Bank and its affiliates) under which such agents may receive compensation
for distribution-related services from the Distributor, including, but not
limited to, commissions or other payments to such agents based on the average
daily net assets of Fund shares attributable to their customers. The Distributor
may retain any portion of the total distribution fee payable thereunder to
compensate it for distribution-related services provided by it or to reimburse
it for other distribution-related expenses.

     General.  The Plan will continue in effect from year to year if such
     -------
continuance is approved by a majority vote of both the Trustees of the Trust and
the Non-Interested Trustees. Any Distribution Agreement related to the Plan also
must be approved by such vote of the Trustees and the Non-Interested Trustees.
Such Agreement will terminate automatically if assigned, and may be terminated
at any time, without payment of any penalty, by a vote of a majority of the
outstanding voting securities of the relevant class of the Fund or by vote of a
majority of the Non-Interested Trustees on not more than 60 days' written
notice. The Plan may not be amended to increase materially the amounts payable
thereunder without the approval of a majority of the outstanding voting
securities of the Fund, and no material amendment to the Plan may be made except
by a majority of both the Trustees of the Trust and the Non-Interested Trustees.

     The Plan requires that the Treasurer of the Trust shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Plan. The Rule also
requires that the selection and nomination of Trustees who are not "interested
persons" of the Trust be made by such disinterested Trustees.

     Wells Fargo Bank, an interested person (as that term is defined in Section
2(a)(19) of the 1940 Act) of the Trust, acts as a selling agent for the Funds'
shares pursuant to selling agreements with Stephens authorized under the Plan.
As a selling agent, Wells Fargo Bank has an indirect financial interest in the
operation of the Plans. The Board of Trustees has concluded that the Plan is
reasonably likely to benefit the Funds and their shareholders because the Plan
authorize the relationships with selling agents, including Wells Fargo Bank,
that have previously developed distribution channels and relationships with the
retail customers that the Funds are designed to serve. These relationships and
distribution channels are believed by the Board to

                                       32
<PAGE>

provide potential for increased Fund assets and ultimately corresponding
economic efficiencies (i.e., lower per-share transaction costs and fixed
expenses) that are generated by increased assets under management.

     Shareholder Servicing Agent.  The Funds have approved a Servicing Plan for
     ---------------------------
the Class A, Class B and Class C shares of the Funds, as applicable, and have
entered into related shareholder servicing agreements with financial
institutions, including Wells Fargo Bank. Under the agreements, Shareholder
Servicing Agents (including Wells Fargo Bank) agree to perform, as agents for
their customers, administrative services, with respect to Fund shares, which
include aggregating and transmitting shareholder orders for purchases, exchanges
and redemptions; maintaining shareholder accounts and records; and providing
such other related services as the Trust or a shareholder may reasonably
request. For providing shareholder services, a Servicing Agent is entitled to a
fee from the applicable Fund, on an annualized basis, of 0.25% of the average
daily net assets of the class of shares owned of record or beneficially by the
customers of the Servicing Agent during the period for which payment is being
made. The Servicing Plan and related forms of shareholder servicing agreements
were approved by the Trust's Board of Trustees and provide that a Fund shall not
be obligated to make any payments under such Plans or related Agreements that
exceed the maximum amounts payable under the Conduct Rules of the NASD.

     General.  The Servicing Plan will continue in effect from year to year if
     -------
such continuance is approved by a majority vote of the Trustees of the Trust,
including a majority of the Trustees who are not "interested periods" (as
defined in the 1940 Act) of the Funds ("Non-Interested Trustees").  Any form of
Servicing Agreement related to the Servicing Plan also must be approved by such
vote of the Trustees and Non-Interested Trustees.  Servicing Agreements may be
terminated at any time, without payment of any penalty, by vote of a majority of
the Board of Trustees, including a majority of the Non-Interested Trustees.  No
material amendment to the Servicing Plan or related Servicing Agreements may be
made except by a majority of both the Trustees of the Trust and the Non-
Interested Trustees.

     The Servicing Plan requires that the Administrator shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Servicing Plan.

     Custodian.  Norwest Bank Minnesota, N.A. ("Norwest Bank") acts as Custodian
     ---------
for each Fund. The Custodian, among other things, maintains a custody account or
accounts in the name of each Fund, receives and delivers all assets for each
Fund upon purchase and upon sale or maturity, collects and receives all income
and other payments and distributions on account of the assets of each Fund, and
pays all expenses of each Fund.  For its services as Custodian, Norwest Bank is
entitled to receive a fee of 0.02% of the average daily net assets of each Fund.

     Fund Accountant.  Forum Financial Services, Inc. acts as Fund Accountant
     ---------------
for the Funds.  The Fund Accountant, among other things, computes net asset
values on a daily basis and performance calculations on a regular basis and as
requested by the Funds.  For providing such services, Forum is entitled to
receive a fee of [___.]

     Transfer and Dividend Disbursing Agent.  State Street Bank, acting through
     --------------------------------------
its affiliate Boston Financial Data Services ("BFDS"), acts as Transfer and
Dividend Disbursing Agent for

                                       33
<PAGE>

the Funds. For providing such services, BFDS is entitled to receive a per-
account fee of [0.04% of the average daily net assets of each such account on an
annual basis].

                           PERFORMANCE CALCULATIONS

     The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

     Performance information for a Fund or Class of shares in a Fund may be
useful in reviewing the performance of such Fund or Class of shares and for
providing a basis for comparison with investment alternatives. The performance
of a Fund and the performance of a Class of shares in a Fund, however, may not
be comparable to the performance from investment alternatives because of
differences in the foregoing variables and differences in the methods used to
value portfolio securities, compute expenses and calculate performance.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

     Average Annual Total Return:  The Funds may advertise certain total return
     ---------------------------
information.  As and to the extent required by the SEC, an average annual
compound rate of return ("T") is computed by using the redeemable value at the
end of a specified period ("ERV") of a hypothetical initial investment ("P")
over a period of years ("n") according to the following formula:  P(1+T)/n/=ERV.

     Cumulative Total Return.  In addition to the above performance information,
     -----------------------
each Fund may also advertise the cumulative total return of the Fund.
Cumulative total return is based on the overall percentage change in value of a
hypothetical investment in the Fund, assuming all Fund dividends and capital
gain distributions are reinvested, without reflecting the effect of any sales
charge that would be paid by an investor, and is not annualized.

     Yield Calculations:  The Funds may, from time to time, include their yields
     ------------------
and effective yields in advertisements or reports to shareholders or prospective
investors.  Quotations of yield for the Funds are based on the investment income
per share earned during a particular seven-day or thirty-day period, less
expenses accrued during a period ("net investment income") and are computed by
dividing net investment income by the offering price per share on the last date
of the period, according to the following formula:

                         YIELD = 2[(a - b + 1)/6/ - 1]
                                    -----
                                    Cd

                                       34
<PAGE>

     where a = dividends and interest earned during the period; b = expenses
accrued for the period (net of reimbursements); c = the average daily number of
shares of each class outstanding during the period that were entitled to receive
dividends; and d = the maximum offering price per share each class of shares on
the last day of the period.

     Effective Yield:  Effective yields for the Funds are based on the change in
     ---------------
the value of a hypothetical investment (exclusive of capital changes) over a
particular thirty-day period, less a pro-rata share of each Fund's expenses
accrued over that period (the "base period"), and stated as a percentage of the
investment at the start of the base period (the "base period return").  The base
period return is then annualized multiplying by 365/30, with the resulting yield
figure carried to at least the nearest hundredth of one percent.  "Effective
yield" for the Funds assumes that all dividends received during the period have
been reinvested.  Calculation of "effective yield" begins with the same "base
period return" used in the calculation of yield, which is then annualized to
reflect weekly compounding pursuant to the following formula:

         Effective Thirty-Day Yield = [Base Period Return +1)365/30]-1

     Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown. Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.  In connection with communicating its yields or total return to
current or prospective shareholders, these figures may also be compared to the
performance of other mutual funds tracked by mutual fund rating services or to
unmanaged indices which may assume reinvestment of dividends but generally do
not reflect deductions for administrative and management costs.

     The yields for each class of shares will fluctuate from time to time,
unlike bank deposits or other investments that pay a fixed yield for a stated
period of time, and do not provide a basis for determining future yields since
they are based on historical data. Yield is a function of portfolio quality,
composition, maturity and market conditions as well as the expenses allocated to
a Fund or to a particular class of a Fund.

     In addition, investors should recognize that changes in the net asset
values of shares of each class of a Fund will affect the yield of the respective
class of shares for any specified period, and such changes should be considered
together with such class' yield in ascertaining such class' total return to
shareholders for the period. Yield information for each class of shares may be
useful in reviewing the performance of the class of shares and for providing a
basis for comparison with investment alternatives. The yield of each class of
shares, however, may not be comparable to the yields from investment
alternatives because of differences in the foregoing variables and differences
in the methods used to value portfolio securities, compute expenses and
calculate yield.

     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Trust may quote the performance or price-
earning ratio of a Fund or a Class of in advertising and other types of
literature as compared with the performance of the S&P Index, the Dow Jones
Industrial Average, the Lehman Brothers 20+ Treasury Index, the Lehman Brothers
5-7 Year Treasury Index, Donoghue's Money Fund Averages, Real Estate Investment
Averages (as

                                       35
<PAGE>

reported by the National Association of Real Estate Investment Trusts), Gold
Investment Averages (provided by the World Gold Council), Bank Averages (which
is calculated from figures supplied by the U.S. League of Savings Institutions
based on effective annual rates of interest on both passbook and certificate
accounts), average annualized certificate of deposit rates (from the Federal
Reserve G-13 Statistical Releases or the Bank Rate Monitor), the Salomon One
Year Treasury Benchmark Index, the Consumer Price Index (as published by the
U.S. Bureau of Labor Statistics), other managed or unmanaged indices or
performance data of bonds, municipal securities, stocks or government securities
(including data provided by Ibbotson Associates), or by other services,
companies, publications or persons who monitor mutual funds on overall
performance or other criteria. The S&P Index and the Dow Jones Industrial
Average are unmanaged indices of selected common stock prices. The performance
of a Fund or a class also may be compared to that of other mutual funds having
similar objectives. This comparative performance could be expressed as a ranking
prepared by Lipper Analytical Services, Inc., CDA Investment Technologies, Inc.,
Bloomberg Financial Markets or Morningstar, Inc., independent services which
monitor the performance of mutual funds. The Funds' performance will be
calculated by relating net asset value per share of each class at the beginning
of a stated period to the net asset value of the investment, assuming
reinvestment of all gains distributions paid, at the end of the period. The
Funds' comparative performance will be based on a comparison of yields, as
described above, or total return, as reported by Lipper, Survey Publications,
Donoghue or Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a class of shares with the performance of a Fund's
competitors. Of course, past performance cannot be a guarantee of future
results.  The Trust also may include, from time to time, a reference to certain
marketing approaches of the Distributor, including, for example, a reference to
a potential shareholder being contacted by a selected broker or dealer. General
mutual fund statistics provided by the Investment Trust Institute may also be
used.

     The Trust also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
each class of shares of a Fund: (i) the Consumer Price Index may be used to
assess the real rate of return from an investment in each class of shares of a
Fund; (ii) other government statistics, including, but not limited to, The
Survey of Current Business, may be used to illustrate investment attributes of
each class of shares of a Fund or the general economic, business, investment, or
financial environment in which a Fund operates; (iii) the effect of tax-deferred
compounding on the investment returns of each class of shares of a Fund or on
returns in general, may be illustrated by graphs, charts, etc., where such
graphs or charts would compare, at various points in time, the return from an
investment in each class of shares of the Fund (or returns in general) on a tax-
deferred basis (assuming reinvestment of capital gains and dividends and
assuming one or more tax rates) with the return on a taxable basis; and (iv) the
sectors or industries in which the Fund invests may be compared to relevant
indices of stocks or surveys (e.g., S&P Industry Surveys) to evaluate the
historical performance or current or potential value of each class of shares of
a Fund with respect to the particular industry or sector.

     The Trust also may use, in advertisements and other types of literature,
information and statements: (1) showing that bank savings accounts offer a
guaranteed return of principal and a fixed rate of interest, but no opportunity
for capital growth; and (2) describing Wells Fargo Bank, and its affiliates and
predecessors, as one of the first investment managers to advise investment
accounts using asset allocation and index strategies. The Trust also may
include in advertising and

                                       36
<PAGE>

other types of literature information and other data from reports and studies
prepared by the Tax Foundation, including information regarding federal and
state tax levels and the related "Tax Freedom Day."

     The Trust also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by an NRSRO, such as Standard Poor's
Corporation. Such rating would assess the creditworthiness of the investments
held by a Fund.  The assigned rating would not be a recommendation to purchase,
sell or hold a Fund's shares since the rating would not comment on the market
price of a Fund's shares or the suitability of a Fund for a particular investor.
In addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to a Fund or its investments. The Trust may compare the performance of each
class of shares of a Fund with other investments which are assigned ratings by
NRSROs. Any such comparisons may be useful to investors who wish to compare each
class' past performance with other rated investments.

     From time to time, a Fund may use the following statements, or variations
thereof, in advertisements and other promotional materials:  "Wells Fargo Bank,
as a Shareholder Servicing Agent for the Wells Fargo Funds Trust, provides
various services to its customers that are also shareholders of the Funds.
These services may include access to Wells Fargo Funds Trust's account
information through Automated Teller Machines (ATMs), the placement of purchase
and redemption requests for shares of the Funds through ATMs and the
availability of combined Wells Fargo Bank and Wells Fargo Funds Trust account
statements."

     The Trust also may disclose, in advertising and other types of literature,
information and statements that Wells Capital Management, Inc. (formerly, Wells
Fargo Investment Management) a subsidiary of Wells Fargo Bank, is listed in the
top 100 by Institutional Investor magazine in its July 1997 survey "America's
Top 300 Money Managers." This survey ranks money managers in several asset
categories. The Trust also may disclose in advertising and other types of sales
literature the assets and categories of assets under management by the Trust's
investment Advisor and the total amount of assets and mutual fund assets managed
by Wells Fargo Bank. As of August 1, 1998, Wells Fargo Bank and its affiliates
provided investment advisory services for approximately $63 billion of assets of
individuals, trusts, estates and institutions and $32 billion of mutual fund
assets.

     The Trust may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels"). Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees. Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely through Electronic Channels. Advertising and other
literature may disclose that Wells Fargo Bank may maintain Web sites, pages or
other information sites accessible through Electronic Channels (an "Information
Site") and may describe the contents and features of the Information Site and
instruct investors on how to access the Information Site and open a Sweep
Account. Advertising and other literature may also disclose the procedures
employed by Wells Fargo Bank to secure information provided by investors,
including disclosure and discussion of the tools and services for accessing
Electronic Channels. Such advertising or other literature may include
discussions of the advantages of

                                       37
<PAGE>

establishing and maintaining a Sweep Account through Electronic Channels and
testimonials from Wells Fargo Bank customers or employees and may also include
descriptions of locations where product demonstrations may occur. The Trust may
also disclose the ranking of Wells Fargo Bank as one of the largest money
managers in the United States.

                       DETERMINATION OF NET ASSET VALUE

     Net asset value per share for each class of the Funds is determined as of
the close of regular trading (currently 1:00 p.m., Pacific time/3:00 p.m.
Central time) on each day the New York Stock Exchange ("NYSE") is open for
business.  Expenses and fees, including advisory fees, are accrued daily and are
taken into account for the purpose of determining the net asset value of the
Funds' shares.

     Securities of a Fund for which market quotations are available are valued
at latest prices. Any security for which the primary market is an exchange is
valued at the last sale price on such exchange on the day of valuation or, if
there was no sale on such day, the latest bid price quoted on such day. In the
case of other Fund securities, including U.S. Government securities but
excluding money market instruments and debt securities maturing in 60 days or
less, the valuations are based on latest quoted bid prices. Money market
instruments and debt securities maturing in 60 days or less are valued at
amortized cost. Futures contracts will be marked to market daily at their
respective settlement prices determined by the relevant exchange. Prices may be
furnished by a reputable independent pricing service approved by the Trust's
Board of Trustees. Prices provided by an independent pricing service may be
determined without exclusive reliance on quoted prices and may take into account
appropriate factors such as institutional-size trading in similar groups of
securities, yield, quality, coupon rate, maturity, type of issue, trading
characteristics and other market data. All other securities and other assets of
a Fund for which current market quotations are not readily available are valued
at fair value as determined in good faith by the Trust's Board of Trustees and
in accordance with procedures adopted by the Trustees.

                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

     Shares of the Funds may be purchased on any day the Funds are open for
business. Each Fund is open for business each day the NYSE is open for trading
(a "Business Day"). Currently, the NYSE is closed 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 a "Holiday"). When any
Holiday falls on a weekend, the NYSE typically is closed on the weekday
immediately before or after such Holiday.

     Payment for shares may, in the discretion of the advisor, be made in the
form of securities that are permissible investments for the Funds. For further
information about this form of payment please contact Stephens. In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that such Fund receives satisfactory
assurances that (i) it will have good and marketable title to the securities
received by it; (ii) that the securities are in proper form for transfer to the
Fund; and (iii) adequate information will be provided concerning the basis and
other matters relating to the securities.

     Under the 1940 Act, the Funds may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit. The Trust may also redeem shares involuntarily or make payment
for redemption in securities or other property if it appears appropriate to do
so in light of the Trust's responsibilities under the 1940 Act. In addition, the
Trust may redeem shares involuntarily to reimburse the Fund for any losses
sustained by reason of the failure of a shareholder to make full payment for
shares purchased or to collect any charge relating to a transaction effected for
the benefit of a shareholder which is applicable to shares of a Fund as provided
from time to time in the Prospectus.

                            PORTFOLIO TRANSACTIONS

     The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities. Subject to policies
established by the Trust's Board of Trustees, Wells Fargo Bank is responsible
for each Fund's portfolio decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Trust to obtain the best results
taking into account the dealer's general execution and operational facilities,
the type of transaction involved and other factors such as the dealer's risk in
positioning the securities involved. While Wells Fargo Bank generally seeks
reasonably competitive spreads or commissions, the Funds will not necessarily be
paying the lowest spread or commission available.

     Purchases and sales of non-equity securities usually will be principal
transactions. Portfolio securities normally will be purchased or sold from or to
dealers serving as market makers for the securities at a net price. Each of the
Funds also will purchase portfolio securities in underwritten offerings and may
purchase securities directly from the issuer. Generally, municipal obligations
and taxable money market securities are traded on a net basis and do not involve
brokerage commissions. The cost of executing a Fund's portfolio securities
transactions will consist primarily of dealer spreads and underwriting
commissions. Under the 1940 Act, persons affiliated with the Trust are
prohibited from dealing with the Trust as a principal in the purchase and sale
of securities unless an exemptive order allowing such transactions is obtained
from the SEC or an exemption is otherwise available. The Fund may purchase
securities from underwriting syndicates of which Stephens or Wells Fargo Bank is
a member under certain conditions in accordance with the provisions of a rule
adopted under the 1940 Act and in compliance with procedures adopted by the
Board of Trustees.

     Wells Fargo Bank, as Investment Advisor to the Funds, may, in circumstances
in which two or more dealers are in a position to offer comparable results for a
Fund portfolio transaction, give preference to a dealer that has provided
statistical or other research services to Wells Fargo Bank. By allocating
transactions in this manner, Wells Fargo Bank is able to supplement its research
and analysis with the views and information of securities firms. Information so
received will be in addition to, and not in lieu of, the services required to be
performed by Wells Fargo Bank under the Advisory Contracts, and the expenses of
Wells Fargo Bank will not necessarily be reduced as a result of the receipt of
this supplemental research information. Furthermore, research services furnished
by dealers through which Wells Fargo Bank places

                                       39
<PAGE>

securities transactions for a Fund may be used by Wells Fargo Bank in servicing
its other accounts, and not all of these services may be used by Wells Fargo
Bank in connection with advising the Funds.

     Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
     ------------------
when Wells Fargo Bank deems portfolio changes appropriate. Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the best interests of the
Funds and their shareholders. The portfolio turnover rate is calculated by
dividing the lesser of purchases or sales of portfolio securities by the average
monthly value of the Fund's portfolio securities. For purposes of this
calculation, portfolio securities exclude all securities having a maturity when
purchased of one year or less. Portfolio turnover generally involves some
expenses to the Funds, including brokerage commissions or dealer mark-ups and
other transaction costs on the sale of securities and the reinvestment in other
securities. Portfolio turnover also can generate short-term capital gain tax
consequences. Portfolio turnover rate is not a limiting factor when Wells Fargo
Bank deems portfolio changes appropriate.

                                 FUND EXPENSES

     From time to time, Wells Fargo Bank and Stephens may waive fees from the
Funds in whole or in part. Any such waiver will reduce expenses and,
accordingly, have a favorable impact on a Fund's performance.

     Except for the expenses borne by Wells Fargo Bank and Stephens, the Trust
bears all costs of its operations, including the compensation of its Trustees
who are not affiliated with Stephens or Wells Fargo Bank or any of their
affiliates; advisory, shareholder servicing and administration fees; payments
pursuant to any Plan; interest charges; taxes; fees and expenses of its
independent auditors, legal counsel, transfer agent and dividend disbursing
agent; expenses of redeeming shares; expenses of preparing and printing
Prospectuses (except the expense of printing and mailing Prospectuses used for
promotional purposes, unless otherwise payable pursuant to a Plan),
shareholders' reports, notices, proxy statements and reports to regulatory
agencies; insurance premiums and certain expenses relating to insurance
coverage; trade association membership dues; brokerage and other expenses
connected with the execution of portfolio transactions; fees and expenses of its
custodian, including those for keeping books and accounts and calculating the
net asset value per share of a Fund; expenses of shareholders' meetings;
expenses relating to the issuance, registration and qualification of a Fund's
shares; pricing services, organizational expenses and any extraordinary
expenses. Expenses attributable to the Fund are charged against Fund assets.
General expenses of the Trust are allocated among all of the funds of the Trust,
including the Funds, in a manner proportionate to the net assets of each Fund,
on a transactional basis, or on such other basis as the Trust's Board of
Trustees deems equitable.

                             FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes." The Prospectuses of each Fund
describe generally the tax treatment of distributions by the Funds. This section
of the SAI includes additional information concerning federal income taxes.

                                       40
<PAGE>

     General.  The Trust intends to qualify each Fund as a regulated investment
     -------
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"), as long as such qualification is in the best interest of the Fund's
shareholders. Each Fund will be treated as a separate entity for federal income
tax purposes. Thus, the provisions of the Code applicable to regulated
investment companies generally will be applied to each Fund, rather than to the
Trust as a whole. In addition, net capital gains, net investment income, and
operating expenses will be determined separately for each Fund. As a regulated
investment company, each Fund will not be taxed on its net investment income and
capital gains distributed to its shareholders.

     Qualification as a regulated investment company under the Code requires,
among other things, that each Fund (a) derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including, but not limited to, gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) diversify its holdings so that,
at the end of each quarter of the taxable year, (i) at least 50% of the market
value of the Fund's assets is represented by cash, government securities and
other securities limited with respect to any one issuer to an amount not greater
than 5% of the Fund's assets and 10% of the outstanding voting securities of
such issuer, and (ii) not more than 25% of the value of its assets is invested
in the securities of any one issuer (other than U.S. Government obligations and
the securities of other regulated investment companies), or in two or more
issuers which the Fund controls and which are determined to be engaged in the
same or similar trades or businesses.

     The Funds also must distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income (which, for this
purpose, includes net short-term capital gains) earned in each taxable year. In
general, these distributions must actually or be deemed to be made in the
taxable year. However, in certain circumstances, such distributions may be made
in the 12 months following the taxable year. Furthermore, distributions declared
in October, November or December of one taxable year and paid by January 31 of
the following taxable year will be treated as paid by December 31 of the first
taxable year. The Funds intend to pay out substantially all of their net
investment income and net realized capital gains (if any) for each year.

     Excise Tax.  A 4% nondeductible excise tax will be imposed on each Fund
     ----------
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

     Taxation of Fund Investments.  Except as provided herein, gains and losses
     ----------------------------
on the sale of portfolio securities by a Fund will generally be capital gains
and losses.  Such gains and losses will ordinarily be long-term capital gains
and losses if the securities have been held by the Fund for more than one year
at the time of disposition of the securities.

                                       41
<PAGE>

     Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by a Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

     If an option granted by a Fund lapses or is terminated through a closing
transaction, such as a repurchase by the Fund of the option from its holder, the
Fund will realize a short-term capital gain or loss, depending on whether the
premium income is greater or less than the amount paid by the Fund in the
closing transaction.  Some realized capital losses may be deferred if they
result from a position which is part of a "straddle," discussed below.  If
securities are sold by the Fund pursuant to the exercise of a call option
written by it, the Fund will add the premium received to the sale price of the
securities delivered in determining the amount of gain or loss on the sale.  If
securities are purchased by a Fund pursuant to the exercise of a put option
written by it, such Fund will subtract the premium received from its cost basis
in the securities purchased.

     The amount of any gain or loss realized by a Fund on closing out a
regulated futures contract will generally result in a realized capital gain or
loss for federal income tax purposes. Regulated futures contracts held at the
end of each fiscal year will be required to be "marked to market" for federal
income tax purposes pursuant to Section 1256 of the Code. In this regard, they
will be deemed to have been sold at market value. Sixty percent (60%) of any net
gain or loss recognized on these deemed sales, and sixty percent (60%) of any
net realized gain or loss from any actual sales, will generally be treated as
long-term capital gain or loss, and the remainder will be treated as short-term
capital gain or loss. Transactions that qualify as designated hedges are
excepted from the "mark-to-market" rule and the "60%/40%" rule.

     Under Section 988 of the Code, a Fund generally will recognize ordinary
income or loss to the extent that gain or loss realized on the disposition of
portfolio securities is attributable to changes in foreign currency exchange
rates. In addition, gain or loss realized on the disposition of a foreign
currency forward contract, futures contract, option or similar financial
instrument, or of foreign currency itself, will generally be treated as ordinary
income or loss. The Funds will attempt to monitor Section 988 transactions,
where applicable, to avoid adverse Federal income tax impact.

     Offsetting positions held by a Fund involving certain financial forward,
futures or options contracts may be considered, for tax purposes, to constitute
"straddles." "Straddles" are defined to include "offsetting positions" in
actively traded personal property. The tax treatment of "straddles" is governed
by Section 1092 of the Code which, in certain circumstances, overrides or
modifies the provisions of Section 1256. If a Fund were treated as entering into
"straddles" by engaging in certain financial forward, futures or option
contracts, such straddles could be characterized as "mixed straddles" if the
futures, forwards, or options comprising a part of such straddles were governed
by Section 1256 of the Code. The Fund may make one or more elections with
respect to "mixed straddles." Depending upon which election is made, if any, the
results with respect to the Fund may differ. Generally, to the extent the
straddle rules apply to positions established by the Fund, losses realized by
the Fund may be deferred to the extent of unrealized gain in any offsetting
positions. Moreover, as a result of the straddle and the conversion transaction
rules, short-term capital loss on straddle positions may be recharacterized

                                       42
<PAGE>

as long-term capital loss, and long-term capital gain may be characterized as
short-term capital gain or ordinary income.

     If a Fund enters into a "constructive sale" of any appreciated position in
stock, a partnership interest, or certain debt instruments, the Fund must
recognize gain (but not loss) with respect to that position.  For this purpose,
a constructive sale occurs when the Fund enters into one of the following
transactions with respect to the same or substantially identical property: (i) a
short sale; (ii) an offsetting notional principal contract; or (iii) a futures
or forward contract.

     Income and dividends received by the Funds from sources within foreign
countries may be subject to withholding and other taxes imposed by such
countries.

     Capital Gain Distributions.  Distributions which are designated by a Fund
     --------------------------
as capital gain distributions will be taxed to shareholders as long-term term
capital gain (to the extent such dividends do exceed the Fund's actual net
capital gains for the taxable year), regardless of how long a shareholder has
held Fund shares.  Such distributions will be designated as capital gain
distributions in a written notice mailed by the Fund to its shareholders not
later than 60 days after the close of the Fund's taxable year.

     Disposition of Fund Shares.  A disposition of Fund shares pursuant to a
     --------------------------
redemption (including a redemption in-kind) or an exchange will ordinarily
result in a taxable capital gain or loss, depending on the amount received for
the shares (or are deemed to be received in the case of an exchange) and the
cost of the shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred in acquiring the Fund's shares shall not be
taken into account (to the extent such previous sales charges do not exceed the
reduction in sales charges on the new purchase) for the purpose of determining
the amount of gain or loss on the disposition, but will be treated as having
been incurred in the acquisition of such other shares.  Also, any loss realized
on a redemption or exchange of shares of the Fund will be disallowed to the
extent that substantially identical shares are acquired within the 61-day period
beginning 30 days before and ending 30 days after the shares are disposed of.

     If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as a long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as a long-term capital loss to the extent of the designated capital gain
distribution.  In addition, if a shareholder holds Fund shares for six months or
less, any loss on the sale or exchange of those shares will be disallowed to the
extent of the amount of exempt-interest dividends received with respect to the
shares.  The Treasury Department is authorized to issue regulations reducing the
six months holding requirement to a period of not less than the greater of 31
days or the period between regular dividend distributions where a Fund regularly
distributes at least 90% of its net tax-exempt interest, if any.  No such
regulations have been issued as of the date of this SAI.  The loss disallowance
rules described in this paragraph do not apply to losses realized under a
periodic redemption plan.

                                       43
<PAGE>

     Federal Income Tax Rates.  As of the printing of this SAI, the maximum
     ------------------------
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 20%; and the maximum corporate tax rate applicable to
ordinary income and net capital gain is 35% (marginal tax rates may be higher
for some corporations to reduce or eliminate the benefit of lower marginal
income tax rates).  Naturally, the amount of tax payable by an individual or
corporation will be affected by a combination of tax laws covering, for example,
deductions, credits, deferrals, exemptions, sources of income and other matters.

     Backup Withholding.  The Trustees may be required to withhold, subject to
     ------------------
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, if the shareholder fails to certify that the Taxpayer
Identification Number ("TIN") provided is correct and that the shareholder is
not subject to backup withholding, or if the IRS notifies the Trust that the
shareholder's TIN is incorrect or that the shareholder is subject to backup
withholding.  Such tax withheld does not constitute any additional tax imposed
on the shareholder, and may be claimed as a tax payment on the shareholder's
federal income tax return.  An investor must provide a valid TIN upon opening or
reopening an account.  Failure to furnish a valid TIN to the Trust could also
subject the investor to penalties imposed by the IRS.

     Corporate Shareholders.  Corporate shareholders of the Funds may be
     ----------------------
eligible for the dividends-received deduction on dividends distributed out of a
Fund's net investment income attributable to dividends received from domestic
corporations, which, if received directly by the corporate shareholder, would
qualify for such deduction.  A distribution by a Fund attributable to dividends
of a domestic corporation will only qualify for the dividends-received deduction
if (i) the corporate shareholder generally holds the Fund shares upon which the
distribution is made for at least 46 days during the 90 day period beginning 45
days prior to the date upon which the shareholder becomes entitled to the
distribution; and (ii) the Fund generally holds the shares of the domestic
corporation producing the dividend income for at least 46 days during the 90 day
period beginning 45 days prior to the date upon which the Fund becomes entitled
to such dividend income.

     Foreign Shareholders.  Under the Code, distributions of net investment
     --------------------
income by the Funds to a nonresident alien individual, foreign trust (i.e.,
trust which a U.S. court is able to exercise primary supervision over
administration of that trust and one or more U.S. persons have authority to
control substantial decisions of that trust), foreign estate (i.e., the income
of which is not subject to U.S. tax regardless of source), foreign corporation,
or foreign partnership (a "foreign shareholder") will be subject to U.S.
withholding tax (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend paid by the Fund to a foreign
shareholder is "effectively connected" with a U.S. trade or business (or, if an
income tax treaty applies, is attributable to a U.S. permanent establishment of
the foreign shareholder), in which case the reporting and withholding
requirements applicable to U.S. persons will apply.  Distributions of net long-
term capital gains are generally not subject to tax withholding.

                                       44
<PAGE>

     New Regulations.  On October 6, 1997, the Treasury Department issued new
     ---------------
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1999, subject to certain
transition rules.  Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders that will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax advisors regarding the
New Regulations.

     Tax-Deferred Plan.  The shares of the Funds are available for a variety of
     -----------------
tax-deferred retirement and other plans, including Individual Retirement
Accounts ("IRA"), Simplified Employee Pension Plans ("SEP-IRA"), Savings
Incentive Match Plans for Employees ("SIMPLE plans"), Roth IRAs, and Education
IRAs, which permit investors to defer some of their income from taxes.
Investors should contact their selling agents for details concerning retirement
plans.

     Additional Considerations for the Tax-Free Income Fund.  If at least 50% of
     ------------------------------------------------------
the value of a regulated investment company's total assets at the close of each
quarter of its taxable years consists of obligations the interest on which is
exempt from federal income tax, it will qualify under the Code to pay "exempt-
interest dividends."  The Tax-Free Income Fund intends to so qualify and is
designed to provide investors with a high level of income exempt from federal
income tax.

     The portion of total dividends paid by the Tax-Free Income Fund with
respect to any taxable year that constitutes exempt-interest dividends will be
the same for all shareholders receiving dividends during such year.
Distributions of capital gains or from net investment income not attributable to
interest on the Fund's tax-exempt obligations will not constitute exempt-
interest dividends and will be taxable to its shareholders.  The exemption of
interest income derived from investments in tax-exempt obligations for federal
income tax purposes may not result in a similar exemption under the laws of a
particular state or local taxing authority.

     Not later than 60 days after the close of its taxable year, the Tax-Free
Income Fund will notify its shareholders of the portion of the dividends paid
with respect to such taxable year which constitutes exempt-interest dividends.
The aggregate amount of dividends so designated cannot exceed the excess of the
amount of interest excludable from gross income under Section 103 of the Code
received by the Fund during the taxable year over any amounts disallowed as
deductions under Sections 265 and 171(a)(2) of the Code.  Interest on
indebtedness incurred to purchase or carry shares of the Tax-Exempt Income Fund
will not be deductible to the extent that the Fund's distributions are exempt
from federal income tax.

     In addition, the federal alternative minimum tax ("AMT") rules ensure that
at least a minimum amount of tax is paid by taxpayers who obtain significant
benefit from certain tax deductions and exemptions.  Some of these deductions
and exemptions have been designated "tax preference items" which must be added
back to taxable income for purposes of calculating AMT.  Among the tax
preference items is tax-exempt interest from "private activity bonds" issued
after August 7, 1986.  To the extent that the Tax-Free Income Fund invests in
private activity bonds, its

                                       45
<PAGE>

shareholders who pay AMT will be required to report that portion of Fund
dividends attributable to income from the bonds as a tax preference item in
determining their AMT. Shareholders will be notified of the tax status of
distributions made by the Tax-Free Income Fund. Persons who may be "substantial
users" (or "related persons" of substantial users) of facilities financed by
private activity bonds should consult their tax advisors before purchasing
shares in the Tax-Free Income Fund. Furthermore, shareholders will not be
permitted to deduct any of their share of the Tax-Free Income Fund's expenses in
computing their AMT. With respect to a corporate shareholder of the Tax-Free
Income Fund, exempt-interest dividends paid by the Fund is included in the
corporate shareholder's "adjusted current earnings" as part of its AMT
calculation, and may also affect its federal "environmental tax" liability. As
of the printing of this SAI, individuals are subject to an AMT at a maximum rate
of 28% and corporations at a maximum rate of 20%. Shareholders with questions or
concerns about AMT should consult their own tax advisors.

     Other Matters.  Investors should be aware that the investments to be made
     -------------
by the Funds may involve sophisticated tax rules that may result in income or
gain recognition by the Funds without corresponding current cash receipts.
Although the Funds will seek to avoid significant noncash income, such noncash
income could be recognized by the Funds, in which case the Funds may distribute
cash derived from other sources in order to meet the minimum distribution
requirements described above.

     The foregoing discussion and the discussions in the Prospectus applicable
to each shareholder address only some of the Federal tax considerations
generally affecting investments in the Funds.  Each investor is urged to consult
his or her tax advisor regarding specific questions as to federal, state, local
or foreign taxes.

                                 CAPITAL STOCK

     The Funds are nine of the funds in the Wells Fargo Funds Trust family of
funds.  The Trust was organized as a Delaware business trust on March 10, 1999.

     Most of the Trust's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors.  Certain of the Trust's funds also are authorized to issue
other classes of shares, which are sold primarily to institutional investors.
Each class of shares in a fund represents an equal, proportionate interest in a
fund with other shares of the same class.  Shareholders of each class bear their
pro rata portion of the fund's operating expenses, except for certain class-
specific expenses (e.g., any state securities registration fees, shareholder
servicing fees or distribution fees that may be paid under Rule 12b-1) that are
allocated to a particular class.  Please contact Shareholder Services at 1-800-
222-8222 if you would like additional information about other funds or classes
of shares offered.

                                       46
<PAGE>

     With respect to matters affecting one class but not another, shareholders
vote as a class; for example, the approval of a Plan.  Subject to the foregoing,
all shares of a Fund have equal voting rights and will be voted in the
aggregate, and not by series, except where voting by a series is required by law
or where the matter involved only affects one series.  For example, a change in
a Fund's fundamental investment policy affects only one series and would be
voted upon only by shareholders of the Fund involved.  Additionally, approval of
an advisory contract, since it affects only one Fund, is a matter to be
determined separately by Series.  Approval by the shareholders of one Series is
effective as to that Series whether or not sufficient votes are received from
the shareholders of the other Series to approve the proposal as to those Series.

     As used in the Prospectus and in this SAI, the term "majority," when
referring to approvals to be obtained from shareholders of a Class of shares of
a Fund, means the vote of the lesser of (i) 67% of the shares of the Class
represented at a meeting if the holders of more than 50% of the outstanding
shares of the Class are present in person or by proxy, or (ii) more than 50% of
the outstanding shares of the Class of the Fund.  The term "majority," when
referring to approvals to be obtained from shareholders of the Fund, means the
vote of the lesser of (i) 67% of the shares of the Fund represented at a meeting
if the holders of more than 50% of the outstanding shares of the Fund are
present in person or by proxy, or (ii) more than 50% of the outstanding shares
of the Fund.  The term "majority," when referring to the approvals to be
obtained from shareholders of the Trust as a whole, means the vote of the lesser
of (i) 67% of the Trust's shares represented at a meeting if the holders of more
than 50% of the Trust's outstanding shares are present in person or by proxy, or
(ii) more than 50% of the Trust's outstanding shares.

     Shareholders are not entitled to any preemptive rights. All shares, when
issued, will be fully paid and non-assessable by the Trust.  The Trust may
dispense with an annual meeting of shareholders in any year in which it is not
required to elect Trustees under the 1940 Act.

     Each share of a class of a Fund represents an equal proportional interest
in the Fund with each other share of the same class and is entitled to such
dividends and distributions out of the income earned on the assets belonging to
the Fund as are declared in the discretion of the Trustees. In the event of the
liquidation or dissolution of the Trust, shareholders of a Fund are entitled to
receive the assets attributable to that Fund that are available for
distribution, and a distribution of any general assets not attributable to a
particular Fund or portfolio that are available for distribution in such manner
and on such basis as the Trustees in their sole discretion may determine.

     Set forth below, as of May 25, 1999, is the name, address and share
ownership of each person known by the Trust to have beneficial or record
ownership of 5% or more of a class of a Fund or 5% or more of the voting

                                   APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate and municipal bonds, municipal notes, and corporate and municipal
commercial paper.

     Corporate Bonds

     Moody's: The four highest ratings for corporate bonds are "Aaa," "Aa," "A"
and "Baa." Bonds rated "Aaa" are judged to be of the "best quality" and carry
the smallest amount of investment risk. Bonds rated "Aa" are of "high quality by
all standards," but margins of protection or other elements make long-term risks
appear somewhat greater than "Aaa" rated bonds. Bonds rated "A" possess many
favorable investment attributes and are considered to be upper medium grade
obligations. Bonds rated "Baa" are considered to be medium grade obligations;
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. Moody's
also applies numerical modifiers in its rating system: 1, 2 and 3 in each rating
category from "Aa" through "Baa" in its rating system. The modifier 1 indicates
that the security ranks in the higher end of its category; the modifier 2
indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks
in the lower end.

     S&P: The four highest ratings for corporate and municipal bonds are "AAA,"
"AA," "A" and "BBB." Bonds rated "AAA" have the "highest rating" assigned by S&P
and have "an extremely strong capacity" to pay interest and repay principal.
Bonds rated "AA" have a "very strong capacity" to pay interest and repay
principal and "differ from the highest rated obligations only in small degree."
Bonds rated "A" have a "strong capacity" to pay interest and repay principal,
but are "somewhat more susceptible" to adverse effects of changes in economic
conditions or other circumstances than bonds in higher rated categories. Bonds
rated "BBB" are regarded as having "adequate protection parameters" to pay
interest and repay principal, but changes in economic conditions or other
circumstances are more likely to lead to a "weakened capacity" to make such
repayments. The ratings from "AA" to "BBB" may be modified by the addition of a
plus or minus sign to show relative standing within the category.

     Commercial Paper

     Moody's: The highest rating for commercial paper is "P-1" (Prime-1).
Issuers rated "P-1" have a "superior ability for repayment of senior short-term
debt obligations." Issuers rated "P-2" (Prime-2) "have a strong capacity for
repayment of senior short-term debt obligations," but earnings trends, while
sound, will be subject to more variation.

                                       50
<PAGE>

     S&P: The "A-1" rating for commercial paper is rated "in the highest
category" by S&P and "the obligor's capacity to meet its financial commitment on
the obligation is strong." The "A-1+" rating indicates that said capacity is
"extremely strong." The A-2 rating indicates that said capacity is
"satisfactory," but that corporate and municipal commercial paper rated "A-2" is
"more susceptible" to the adverse effects of changes in economic conditions or
other circumstances than commercial paper rated in higher rating categories.

Summary Of Important Risks

This section summarizes important risks that are common to all of the Funds
described in this Prospectus, and important risks that relate specifically to
particular Funds. Both are important to your investment choice. Additional
information about these and other risks is included in the individual Fund
Descriptions later in this Prospectus, under General Investment Risks beginning
on page __ and in the Funds' Statement of Additional Information. An investment
in a Fund is not a deposit of Wells Fargo Bank and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.

Common Risks for the Funds

Equity Securities. The Funds invest in equity securities, which are subject to
equity market risk. This is the risk that stock prices will fluctuate and can
decline and reduce the value of a Fund's portfolio. Certain types of stock and
certain individual stocks selected for a Fund's portfolio may underperform or
decline in value more than the overall market. As of the date of this
Prospectus, the equity markets, as measured by the S&P 500 Index and other
commonly used indexes, are trading at or close to record levels. There can be no
guarantee that these levels will continue. The Funds that invest in smaller
companies, in foreign companies (including investments made through American
Depositary Receipts ("ADRs") and similar instruments), and in emerging markets
are subject to additional risks, including less liquidity and greater price
volatility. A Fund's investment in foreign companies and emerging markets are
also subject to special risks associated with international investing, including
currency, political, regulatory and diplomatic risks.

Debt Securities. The Funds may invest in debt instruments, such as notes and
bonds, which are subject to credit risk and interest rate risk. Credit risk is
the possibility that an issuer of an instrument will be unable to make interest
payments or repay principal. Changes in the financial strength of an issuer or
changes in the credit rating of a security may affect its value. Interest rate
risk is the risk that interest rates may increase, which will reduce the resale
value of instruments in a Fund's portfolio, including U.S. Government
obligations. Debt instruments with longer maturities are generally more
sensitive to interest rate changes than those with shorter maturities. Changes
in market interest rates do not affect the rate payable on debt instruments held
in a Fund, unless the instrument has adjustable or variable rate features, which
can reduce interest rate risk. Changes in market interest rates may also extend
or shorten the duration of certain types of instruments, such as asset-backed
securities, thereby affecting their value and the return on your investment.

Fund-Specific Risks

Corporate Bond Fund
We may invest in debt securities that are in low or below investment grade
categories, or are unrated or in default at the time of purchase. Such debt
securities have a much greater risk of default (or in the case of bonds
currently in default, of not returning principal) and are more volatile than
higher-rated securities of similar maturity. The value of such debt securities
will be affected by overall economic conditions, interest rates, and the
creditworthiness of the individual issuers. Additionally, these lower rated debt
securities may be less liquid and more difficult to value than higher rated
securities.

Stocks of the smaller and medium-sized companies in which the Fund may invest
may be more volatile than larger company stocks. Investments in foreign markets
may also present special risks, including currency, political, diplomatic,
regulatory and liquidity risks.

                                       5
<PAGE>

Stable Income Fund

The U.S. Government does not guarantee the market value or current yield of its
obligations. Not all U.S. Government obligations are backed by the full faith
and credit of the U.S. Government. Mortgage-backed securities are subject to
prepayment risk and to extension risk, either of which can reduce the rate of
return on the portfolio.

Income Plus Fund

We may invest in debt securities that are in low or below investment grade
categories, or are unrated or in default at the time of purchase. Such debt
securities have a much greater risk of default (or in the case of bonds
currently in default, of not returning principal) and are more volatile than
higher-rated securities of similar maturity. The value of such debt securities
will be affected by overall economic conditions, interest rates, and the
creditworthiness of the individual issuers. Additionally, these lower rated debt
securities may be less liquid and more difficult to value than higher rated
securities.

Stocks of the smaller and medium-sized companies in which the Fund may invest
may be more volatile than larger company stocks. Investments in foreign markets
may also present special risks, including currency, political, diplomatic,
regulatory and liquidity risks.

Variable Rate Government Fund

Adjustable rate mortgages ("ARMS") have interest rates tied to an index, such as
U.S. Treasury bill rates or the federal funds target rate, so that payments may
be periodically reset according to changes in the index. Individual ARMS are
bundled together and sold as securities. Unlike conventional debt securities,
which typically make semi-annual interest payments and repay principal at
maturity, ARMs provide a monthly payment of a pro-rated share of both interest
payments and payments and pre-payments of principal. Since ARMs adjust to
interest rate changes, they may be less sensitive to interest rate changes than
their weighted-average maturity might suggest.

Performance History

The Funds in this prospectus will commence operations in September 1999. No
performance information is given for the Funds because they will have been in
operation for less than one year.

Corporate Bond Fund

Investment Objective
The Corporate Bond Fund seeks a high level of current income consistent with
prudent investment risk.

Investment Policies
We seek a high rate of current income by actively managing a diversified
portfolio consisting primarily of corporate debt securities. When purchasing
these securities we consider, among other things, the yield differences for
various corporate sectors, and the current economic cycle's potential effect on
the various types of bonds. We may invest in securities of any maturity. Under
normal market conditions, we expect to maintain a dollar-weighted average
maturity for portfolio securities of between 10 and 15 years. We also may invest
in U.S. Government obligations.

Permitted Investments
Under normal market conditions, we invest:

 .    at least 65% of our total assets in corporate debt securities;
 .    in U.S. Government obligations;
 .    no more than 25% of our total assets in debt securities that are below
     investment grade; and
 .    no more than 25% of our total assets in securities of foreign issuers.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, either to maintain liquidity
or for short-term defensive purposes when we believe it is in the best interests
of shareholders to do so. During such periods, the Fund may not achieve its
investment objective.

Important Risk Factors
We may invest in securities regardless of their rating or in securities that are
unrated, or in default at the time of purchase.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above. They
are all important to your investment choice.

Stable Income Fund

Investment Objective
The Stable Income Fund seeks to maintain stability of principal while providing
low volatility total return.

Investment Policies
The Fund invests primarily in short-term Investment Grade securities. The Fund
invests in a diversified portfolio of fixed and variable rate U.S. dollar-
denominated fixed income securities of a broad spectrum of U.S. and foreign
issuers, including U.S. Government securities and the debt securities of
financial institutions, corporations, and others.

Permitted Investments
Under normal market conditions, we invest:

 .    mortgage-backed securities to not more than 65% of its total assets;
 .    other types of asset-backed securities to not more than 25% of its total
     assets;
 .    mortgage-backed securities that are not U.S. Government securities to not
     more than 25% of its total assets; and
 .    U.S. Government securities to not more than 50% of its total assets.

The Fund may not invest more than 30% of its total assets in the securities
issued or guaranteed by any single agency or instrumentality of the U.S.
Government, except the U.S. Treasury, and may not invest more than 10% of its
total assets in the securities of any other issuer.

The Fund only purchases Investment Grade securities. The Fund invests in debt
obligations with maturities (or average life in the case of mortgage-backed and
similar securities) ranging from overnight to 12 years and seeks to maintain an
average dollar-weighted portfolio maturity of between 2 and 5 years.

The Fund may use options, swap agreements, interest rate caps, floors, collars,
and futures contracts to manage risk. The Fund also may use options to enhance
return.

Important Risk Factors
You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above. They
are all important to your investment choice.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure. In this structure, a
"gateway" fund invests all of its assets in a "core" portfolio that has a
substantially identical investment objective and substantially similar policies
as the gateway fund. Gateway funds investing in the same core portfolio can
enhance their investment opportunities and reduce their expense ratios through
sharing the costs of managing a large pool of assets. References to the
investment activities of the Fund also refer to the core portfolio.

Income Plus Fund

Investment Objective
The Income Plus Fund seeks to maximize income while maintaining prospects for
capital appreciation.

Investment Policies
We actively manage a diversified portfolio of debt securities and income-
producing equity securities selected with particular consideration for their
potential to generate current income. We shift assets between such debt and
equity securities based on our assessment of the potential income available. We
may buy debt securities that are below investment grade (sometimes referred to
as "junk bonds"), as well as debt rated in the lower investment grade
categories. Our equity focus will be on securities issued by companies in
industries that tend to pay high ongoing dividends, such as utilities. We may
buy preferred stock and other convertible securities, as well as common stock of
any size company. Any capital appreciation will come primarily from the income-
producing equity portion of the portfolio.

Permitted Investments
Under normal market conditions, we invest:

 .    at least 25% of our total assets in corporate and government bonds;
 .    up to 60% of our total assets in a wide range of income-producing equity
     securities.;
 .    up to 50% of our total assets in debt securities that are below investment
     grade, including "high risk" securities; and
 .    no more than 25% of our total assets in securities of foreign issuers.

We will generally invest in debt securities that are rated at least "Caa" by
Moody's or "CCC" by S&P, or that are unrated but deemed by the advisor to be of
comparable equity. The average credit quality of this portion of the portfolio
is expected to be "BB" as rated by S&P.

Important Risk Factors
We may invest in debt securities that are in low or below investment grade
categories, or are unrated or in default at the time of purchase. Such debt
securities have a much greater risk of default (or in the case of bonds
currently in default, of not returning principal) and are more volatile than
higher-rated securities of similar maturity. The value of such debt securities
will be affected by overall economic conditions, interest rates, and the
creditworthiness of the individual issuers. Additionally, these lower rated debt
securities may be less liquid and more difficult to value than higher rated
securities.

Stocks of the smaller and medium-sized companies in which the Fund may invest
may be more volatile than larger company stocks. Investments in foreign markets
may also present special risks, including currency, political, diplomatic,
regulatory and liquidity risks.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __ and the specific risks listed above. They
are both important to your investment choice.

Portfolio Managers
Scott Smith and Jacqueline Flipping are the managers of the income portion of
the Fund, Allen Wisniewski is the manager of the income-producing equity
portions of the Fund, and Graham Allen manages the international and below
investment grade portions of the Fund. They jointly determine the Fund's asset
allocation.

Variable Rate Government Fund

Investment Objective
The Variable Rate Government Fund seeks to earn a high level of current income,
while reducing principal volatility, by investing primarily in adjustable rate
mortgage securities issued or guaranteed by the U.S. Government, its agencies
and instrumentalities.

Investment Policies
We actively manage a diversified portfolio primarily of adjustable rate mortgage
securities, also known as "ARMS."  We invest in obligations of any maturity, but
under ordinary conditions we will maintain a dollar-weighted average maturity of
between 10 to 30 years.  In unusual circumstances, the dollar-weighted average
maturity may be below 10 years.  We also may invest in U.S. Treasury securities
with remaining maturities of up to 5 years.

Permitted Investments
Under normal market conditions, we invest:

 .    at least 65% of our total assets in ARMS issued or guaranteed by the U.S.
     Government, its agencies or instrumentalities;
 .    in adjustable rate portions of collateralized mortgage obligations ("CMOs")
     issued by U.S. Government agencies and CMO's rated "AAA" by S&P, or "Aaa"
     by Moody's; and
 .    no more than 5% of our assets in securities purchased on a "when-issued"
     basis.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, either to maintain liquidity
or for short-term defensive purposes when we believe it is in the best interests
of shareholders to do so. During such periods, the Fund may not achieve its
investment objective.

Important Risk Factors
The U.S. Government does not directly or indirectly insure or guarantee the
performance of the Fund.  Mortgage-backed securities are subject to the risk
that homeowners may refinance existing mortgages to take advantage of lower
rates.  Such "prepayments" result in an early return of principal that is then
reinvested at what is likely to be a lower yield.

Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds.  Certain common risks are identified in the
Summary of Important Risks on page ___.  Other risks of mutual fund investing
include the following:

 .    Unlike bank deposits such as CDs or savings accounts, mutual funds are not
     insured by the FDIC.

 .    We cannot guarantee that we will meet our investment objectives.

 .    We do not guarantee the performance of a Fund, nor can we assure you that
     the market value of your investment will not decline. We will not "make
     good" any investment loss you may suffer, nor can anyone we contract with
     to provide certain services, such as selling agents or investment advisors,
     offer or promise to make good any such losses.

 .    Share prices -- and therefore the value of your investment -- will increase
     and decrease with changes in the value of the underlying securities and
     other investments. This is referred to as price volatility.

 .    Investing in any mutual fund, including those deemed conservative, involves
     risk, including the possible loss of any money you invest.

 .    An investment in a single Fund, by itself, does not constitute a complete
     investment plan.

 .    The Funds that invest in smaller companies, foreign companies (including
     investments made through ADRs and similar instruments), and in emerging
     markets are subject to additional risks, including less liquidity and
     greater price volatility. A Fund's investment in foreign and emerging
     markets may also be subject to special risks associated with international
     trade, including currency, political, regulatory and diplomatic risk.

 .    The Funds may invest a portion of their assets in U.S. Government
     obligations. It is important to recognize that the U.S. Government does not
     guarantee the market value or current yield of those obligations. Not all
     U.S. Government obligations are backed by the full faith and credit of the
     U.S. Treasury, and the U.S. Government's guarantee does not extend to the
     Funds themselves.

 .    The Funds may also use certain derivative instruments, such as options or
     futures contracts. The term "derivatives" covers a wide number of
     investments, but in general it refers to any financial instrument whose
     value is derived, at least in part, from the price of another security or a
     specified index, asset or rate. Some derivatives may be more sensitive to
     interest rate changes or market moves, and some may be susceptible to
     changes in yields or values due to their structure or contract terms.

 .    The Funds may temporarily hold assets in cash or in money market
     instruments, including U.S. Government obligations, shares of other mutual
     funds and repurchase agreements, or make other short-term investments,
     either to maintain liquidity or for short-term defensive purposes when we
     believe it is in the best interests of shareholders to do so. To the extent
     a Fund's assets are so invested, they may cause a Fund to not achieve its
     investment objective. This practice is expected to have limited, if any,
     effect on the Funds' pursuit of their objectives over the long term.

 .    The Funds invest a portion of their assets in U.S. Government obligations,
     such as securities issued or guaranteed by the Government National Mortgage
     Association ("GNMAs"), the Federal National Mortgage Association ("FNMAs")
     and the Federal Home Loan Mortgage Corporation ("FHLMCs"). Each are
     mortgage-backed securities representing partial ownership of a pool of
     residential mortgage loans. A "pool" or group of such mortgages is
     assembled and, after being approved by the issuing or guaranteeing entity,
     is offered to investors through securities dealers. Mortgage-backed
     securities are subject to prepayment and extension risk, which can alter
     the maturity of the securities and also reduce the rate of return on the
     portfolio. Collateralized mortgage obligations ("CMOs") typically represent
     principal-only and interest-only portions of such securities and are
     subject to increased interest-rate and credit risk.

                                       15
<PAGE>

General Investment Risks (Cont'd)

 .    The market value of lower-rated debt securities and unrated securities of
     comparable quality that the Funds may invest in tends to reflect individual
     developments affecting the issuer to a greater extent than the market value
     of higher-rated securities, which react primarily to fluctuations in the
     general level of interest rates. Lower-rated securities also tend to be
     more sensitive to economic conditions than higher-rated securities. These
     lower-rated debt securities are considered by the rating agencies, on
     balance, to be predominantly speculative with respect to the issuer's
     capacity to pay interest and repay principal. These securities generally
     involve more credit risk than securities in higher-rating categories. Even
     securities rated "BBB" by S&P or by Moody's ratings which are considered
     investment-grade, possess some speculative characteristics.

Investment practices and risk levels are carefully monitored.  Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Fund and a table showing some of the
additional investment practices that each Fund may use and the risks associated
with them.  Additional information about these practices is available in the
Statement of Additional Information.

Counter-Party Risk--The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule.  If an issuer does default,
the affected security could lose all of its value, or be renegotiated at a lower
interest rate or principal amount.  Affected securities might also lose
liquidity.  Credit risk also includes the risk that a party in a transaction may
not be able to complete the transaction as agreed.

Currency Risk-- The risk that a change in the exchange rate between U.S. dollars
and a foreign currency may reduce the value of an investment made in a security
denominated in that foreign currency.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value of
liquidity of investments in either country.

Emerging Market Risk--The risk that the emerging market, as defined in the
glossary, may be more sensitive to certain economic changes.  For example,
emerging market countries are often dependent on international trade and are
therefore often vulnerable to recessions in other countries.  They may have
obsolete financial systems, have volatile currencies and may be more sensitive
than more mature markets to a variety of economic factors.  Emerging market
securities may also be less liquid than securities of more developed countries
and could be difficult to sell, particularly during a market downturn.

Experience Risk--The risk presented by a new or innovative security.  The risk
is that insufficient experience exists to forecast how the security's value
might be affected by various economic conditions:

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security.  Generally, when interest rates increase, the value of
a debt security decreases.  The effect is usually more pronounced for securities
with longer dates to maturity.

Leverage Risk--The risk that a practice may increase a Fund's exposure to market
risk, interest rate risk or other risks by, in effect, increasing assets
available for investment.

                                       16
<PAGE>

General Investment Risks (Cont'd)

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of a stock, bond or other security will be
reduced by market activity.  This is a basic risk associated with all
securities.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

Prepayment Risk--The risk that consumers will accelerate their prepayment of
mortgage loans or other receivables, which can shorten the maturity of mortgage-
backed or other asset-backed securities, and reduce a portfolio's rate of
return.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.  Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Year 2000 Risk--The Funds' principal service providers have advised the Funds
that they are working on the necessary changes to their computer systems to
avoid any system failure based on an inability to distinguish the year 2000 from
the year 1900, and that they expect their systems to be adapted in time.  There
can, of course, be no assurance of success.  In addition, the companies or
entities in which the Funds invest also could be adversely impacted by the Year
2000 issue, especially foreign entities, which may be less prepared for Year
2000.  The extent of such impact cannot be predicted.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund.  You should also
see the Statement of Additional Information for additional information about the
investment practices and risks particular to each Fund.

Organization and Management of the Funds

A number of different entities provide services to the Funds.  This section
shows how the Funds are organized, lists the entities that perform different
services, and explains how these service providers are compensated.  Further
information is available in the Statement of Additional Information for the
Funds.

About Wells Fargo Funds Trust
Wells Fargo Funds Trust (the "Trust") was organized as a Delaware business trust
on March 10, 1999.  The Board of Trustees of the Trust supervises each Fund's
activities, monitors its contractual arrangements with various service providers
and decides upon matters of general policy.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds.  The holding company of Wells Fargo Bank, the investment advisor to
the Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998.  Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one or more Stagecoach
and/or Norwest Advantage Funds.  One of these predecessor funds is expected to
be the "accounting survivor," which means that its performance and financial
statement history will be assumed by the Wells Fargo Funds Trust Fund.  The
succession transactions are conditioned on shareholder approval by the
shareholders of the various Stagecoach and Norwest Advantage Funds.  The Table
on page __ identifies the expected accounting survivors.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund class paid on an annual basis for the
services described.

The Board of Trustees of Wells Fargo Funds Trust supervises the Funds'
activities and approves the selection of various companies hired to manage the
Funds' operation. The major service providers are described in the diagram
below. Except for the advisors, which require shareholder vote to change, if the
Board believes that it is in the best interests of the shareholders it may make
a change in one of these companies.

A Choice of Share Classes
After choosing a Fund, your next most important choice is which share class to
buy.  The following classes of shares are available through this Prospectus:
 .  Class A Shares - with a front-end sales charge, volume reductions and lower
   on-going expenses than Class B and Class C shares.
 .  Class B Shares - with a contingent deferred sales charge ("CDSC") payable
   upon redemption that diminishes over time, and higher on-going expenses than
   Class A shares.
 .  Class C Shares - with a 1.00% CDSC on redemptions made within one year of
   purchase, and higher on-going expenses than Class A shares.

The choice between share classes is largely a matter of preference.  You should
consider, among other things, the different fees and sales loads assessed on
each share class and the length of time you anticipate holding your investment.
If you prefer to pay sales charges up front, wish to avoid higher on-going
expenses, or, more importantly, you think you may qualify for volume discounts
based on the amount of your investment, then Class A shares may be the choice
for you.

You may prefer to see "every dollar working" from the moment you invest.  If so,
then consider Class B or Class C shares.  Please note that Class B shares
convert to Class A shares after seven years to avoid the higher on-going
expenses assessed against Class B shares.

Class B shares are available for the Corporate Bond, Stable Income and Income
Plus Funds only. Class C shares are available for the Corporate Bond and Income
Plus Funds only. They are similar to Class B shares, with some important
differences. Unlike Class B shares, Class C shares do not convert to Class A
shares. The higher on-going expenses will be assessed as long as you hold the
shares. The choice between Class B and Class C shares may depend on how long you
intend to hold Fund shares before redeeming them.

Please see the expenses listed for each Fund and the following sales charge
schedules before making your decision.  You should also review the "Reduced
Sales Charges" section of the Prospectus.  You may wish to discuss this choice
with your financial consultant.

Class A Share Sales Charge Schedule
If you choose to buy Class A shares, you will pay the Public Offering Price
("POP") which is the Net Asset Value ("NAV") plus the applicable sales charge.
The money market funds listed in this prospectus do not impose sales charges on
the purchase of Class A shares.  Since sales charges are reduced for Class A
share purchases above certain dollar amounts, known as "breakpoint levels", the
POP is lower for these purchases.

Class B Share CDSC Schedule
If you choose Class B shares, you buy them at NAV and agree that if you redeem
your shares within six years of the purchase date, you will pay a CDSC based on
how long you have held your shares.  Certain exceptions apply (see "Class B and
Class C Share CDSC Reductions" and "Waivers for Certain Parties").  The CDSC
schedule is as follows:

- -----------------------------------------------------------------------------------------
</TABLE>

The CDSC percentage you pay is based on the lower of the NAV of the shares
on the date of the original purchase, or the NAV of the shares on the date of
redemption.

We always process partial redemptions so that the least expensive shares are
redeemed first in order to reduce your sales charges.  After shares are held for
six years, the CDSC expires.  After shares are held for seven years, the Class B
shares are converted to Class A shares to reduce your future on-going expenses.

Class B shares received in the reorganization of the Stagecoach Funds are
subject to the above CDSC schedule based on the purchase date(s) of the
Stagecoach shares, and such shares convert to Class A shares automatically after
six years.

Class B shares received in the reorganization of the Stagecoach Funds in
exchange for Stagecoach Fund shares that were purchased prior to March 3, 1997
are subject to a CDSC if they are redeemed within four years of the original
purchase.  The CDSC Schedule for these shares is below:

The above-described schedules for shares of the former Stagecoach Funds and

exchange the Class B shares received in the reorganization for Class B shares of
another Fund, you will retain these CDSC schedules on your exchanged shares.
Additional shares purchased will age at the higher CDSC schedule.

Class C Share CDSC Schedule
If you choose Class C shares, you buy them at NAV and agree that if you redeem
your shares within one year of the purchase date, you will pay a CDSC of 1.00%.

The CDSC percentage you pay is based on the lower of the NAV on the date of the
original purchase, or the NAV on the date of redemption.  The distributor pays
sales commissions of up to 1.00% of the purchase price of Class C shares to
selling agents at the time of the sale, and up to 1.00% annually thereafter.

We always process partial redemptions so that the least expensive shares are
redeemed first in order to reduce your sales charges.  Class C shares do not
convert to Class A shares, and therefore continue to pay the higher on-going
expenses.

                                       25

Reduced Sales Charges
Generally, we offer more sales charge reductions for Class A shares than for
Class B and Class C shares, particularly if you intend to invest greater
amounts.  You should consider whether you are eligible for any of the potential
reductions when you are deciding which share class to buy.

Class A Share Reductions:  [PLEASE CONFIRM]

 .    You pay no sales charges on Fund shares you buy with reinvested
     distributions.
 .    You pay a lower sales charge if you are investing an amount over a
     breakpoint level. See the "Class A Share Sales Charge Schedule" above.
 .    By signing a Letter of Intent (LOI), you pay a lower sales charge now in
     exchange for promising to invest an amount over a specified breakpoint
     within the next 13 months. We will hold in escrow shares equal to
     approximately 5% of the amount you intend to buy. If you do not invest the
     amount specified in the LOI before the expiration date, we will redeem
     enough escrowed shares to pay the difference between the reduced sales load
     you paid and the sales load you should have paid. Otherwise, we will
     release the escrowed shares when you have invested the agreed amount.
 .    Rights of Accumulation (ROA) allow you to combine the amount you invest
     with the total NAV of shares you own in other Stagecoach or Norwest
     Advantage front-end load Funds in order to reach breakpoint levels for a
     reduced load. We give you a discount on the entire amount of the investment
     that puts you over the breakpoint level.
 .    If you are reinvesting the proceeds of a Stagecoach Fund redemption for
     shares on which you have already paid a front-end sales charge, you have
     [120] days to reinvest the proceeds of that redemption with no sales charge
     into a Fund that charges the same or a lower front-end sales charge. If you
     use such a redemption to purchase shares of a Fund with a higher front-end
     sales charge, you will have to pay the difference between the lower and
     higher charge.
 .    You may reinvest into a Wells Fargo Fund with no sales charge a required
     distribution from a pension, retirement, benefits, or similar plan for
     which Wells Fargo Bank acts as trustee provided the distribution occurred
     within the 30 days prior to your reinvestment.

If you believe you are eligible for any of these reductions, it is up to you to
ask the selling agent or the shareholder servicing agent for the reduction and
to provide appropriate proof of eligibility.

You, or your fiduciary or trustee, may also tell us to extend volume discounts,
including the reductions offered for rights of accumulation and letters of
intent, to include purchases made by:

 .    a family unit, consisting of a husband and wife and children under the age
     of twenty-one or single trust estate;
 .    a trustee or fiduciary purchasing for a single fiduciary relationship; or
 .    the members of a "qualified group" which consists of a "company" (as
     defined in the Investment Company Act of 1940 ("1940 Act")), and related
     parties of such a "Company," which has been in existence for at least six
     months and which has a primary purpose other than acquiring Fund shares at
     a discount.

How a Letter of Intent Can Save You Money!
If you plan to invest, for example, $100,000 in a Wells Fargo Fund in
installments over the next year, by signing a letter of intent you would pay
only  3.75% sales load on the entire purchase.  Otherwise, you might pay 5.75%
on the first $50,000, then 4.75% on the next $49,999!

Class B and Class C Share CDSC Reductions:
 .    You pay no CDSC on Funds shares you purchase with reinvested distributions.
 .    We waive the CDSC for all redemptions made because of scheduled or
     mandatory distributions for certain retirement plans. (See your retirement
     plan disclosure for details.)

                                       26

Reduced Sales Charges (Cont'd)

 .    We waive the CDSC for redemptions made in the event of the shareholder's
     death or for a disability suffered after purchasing shares. ("Disability"
     is defined by the Internal Revenue Code of 1986.)
 .    We waive the CDSC for redemptions made at the direction of Wells Fargo in
     order to, for example, complete a merger or close an account whose value
     has fallen below the minimum balance.
 .    We waive Class C share CDSC for certain types of accounts.

For Class B shares purchased [outside of an IRA] or other qualified plan after
May 18, 1999 for former Stagecoach Fund shareholders, and after September 17,
1999 for all other shareholders, no CDSC is imposed on withdrawals that occur
under the following circumstances:
 .    Withdrawals are made by participating in the Systematic Withdrawal Plan;
 .    Withdrawals may not exceed 10% of your fund assets annually based on your
     anniversary date in the Systematic Withdrawal Plan; and
 .    you must participate in the dividend and capital gain reinvestment program.

Waiver for Certain Parties
If you are eligible for certain waivers, we will sell you Class A shares so you
can avoid higher on-going expenses.  The following people can buy Class A shares
at NAV:
 .    Current and retired employees, directors and officers of:
     .    Wells Fargo Funds and its affiliates;
     .    Wells Fargo Bank, Norwest Bank and their affiliates;
     .    Stephens and its affiliates; and
     .    Broker-Dealers who act as selling agents.
 .    [The spouses of any of the above, as well as the grandparents, parents,
     siblings, children, grandchildren, aunts, uncles, nieces, nephews, fathers-
     in-law, mothers-in-law, brothers-in-law and sisters-in-law of either the
     spouse or the current or retired employee, director of officer.]

You may also buy Class A Fund shares at NAV if they are to be included in
certain retirement, benefits, pension or investment "wrap accounts" with whom
Wells Fargo Funds has reached an agreement, or through an omnibus account
maintained with a Fund by a broker/dealer.

We reserve the right to enter into agreements that reduce or eliminate sales
charges for groups or classes of shareholders, or for Fund shares included in
other investment plans such as "wrap accounts."  If you own Fund shares as part
of another account or package such as an IRA or a sweep account, you must read
the directions for that account.  These directions may supersede the terms and
conditions discussed here.

Distribution Plan
We have adopted Distribution Plans for the Class A, Class B and Class C shares
of the Funds.  The plans authorize the payment of all or part of the cost of
preparing and distributing prospectuses and distribution-related services
including ongoing compensation to selling agents.  The plan also provides that,
if and to the extent any shareholder servicing payments are recharacterized as
payments for distribution-related services, they are approved and payable under
the distribution plan.  The fees paid under these plans are as follows:

Variable Rate Government Fund           N/A           --            --
- -------------------------------------------------------------------------
</TABLE>

These fees are paid out of the Funds' assets on an on-going basis.  Overtime,
these fees will increase the cost of your investment and may cost you more than
paying other types of sales charges.

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:
 .  As with all mutual fund investments, the price you pay to purchase shares or
   the price you receive when you redeem shares is not determined until after a
   request has been received in proper form.
 .  We determine the Net Asset Value ("NAV") of each class of the Funds' shares
   each business day as of the close of regular trading on the NYSE. We
   determine the NAV by subtracting the Fund class's liabilities from its total
   assets, and then dividing the result by the total number of outstanding
   shares of that class. Each Fund's assets are generally valued at current
   market prices. See the Statement of Additional Information for further
   disclosure.
 .  We process requests to buy or sell shares of the Funds each business day as
   of the close of regular trading on the New York Stock Exchange ("NYSE"),
   which is usually 1:00 p.m. (Pacific time)/3:00 p.m. (Central time). If the
   markets close early, the Funds may close early and may value their shares at
   earlier times under these circumstances. Any request we receive in proper
   form before these times is processed the same day. Requests we receive after
   the cutoff times are processed the next business day.
 .  The funds are open for business on each day the NYSE is open for business.
   NYSE holidays include New Year's Day, Martin Luther King, Jr. Day,
   President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
   Thanksgiving Day and Christmas Day. When any holiday falls on a weekend, the
   NYSE typically is closed on the weekday immediately before or after such
   holiday.

You can buy Fund shares:
 .  By opening an account directly with the Fund (simply complete and return a
   Wells Fargo Funds application with proper payment);
 .  Through a brokerage account with an approved selling agent; or
 .  Through certain retirement, benefits and pension plans, or through certain
   packaged investment products (please see the providers of the plan for
   instructions).

Minimum Investments:
 .  $1,000 per Fund minimum initial investment;1
 .  $5,000 minimum initial investment for the Stable Income Fund; or
 .  $100 per Fund if you use the Systematic Purchase Program; and
 .  $100 per Fund for all investments after your first.

/1/  [Purchases of Class B shares in amounts of $250,000 or more require the
     prior approval of your selling agent.]

We may waive the minimum for Funds you purchase through certain retirement,
benefit and pension plans, through certain packaged investment products, or for
certain classes of shareholders as permitted by the SEC.  Check the specific
disclosure statements and applications for the program through which you intend
to invest.

GENERAL NOTES FOR SELLING SHARES
- --------------------------------------------------------------------------------
We determine the NAV of the funds each day as of the close of regular trading on
the NYSE, which is generally 1:00 PM (Pacific time)/3:00 P.M. (Central time).
- --------------------------------------------------------------------------------
Your redemptions are net of any applicable CDSC.
- --------------------------------------------------------------------------------
We will process requests to sell shares at the first NAV calculated after a
request in proper form is received. Requests received before the cutoff times
are processed on the same business day.
- --------------------------------------------------------------------------------
If your purchased shares through a packaged investment product or retirement
plan, read the directions for selling shares provided by the product or plan.
There maybe special requirements that supersede the directions in this
Prospectus.
- --------------------------------------------------------------------------------
We reserve the right to delay payment of a redemption so that we may be
reasonably certain that investments made by check or Systematic Purchase Plan
have been collected. Payments of redemptions also may be delayed under
extraordinary circumstances or as permitted by the SEC in order to protect
remaining shareholders.
- --------------------------------------------------------------------------------
Generally, we pay redemption requests in cash, unless the redemption request is
for more than $250,000 or 1% of the net assets of the Fund by a single
shareholder over any ninety-day period. If a request for a redemption is over
these limits, it may be to the detriment of existing shareholders to pay such
redemption in cash. Therefore, we may pay all or part of the redemption in
securities of equal value.

Exchanges

Exchanges between Wells Fargo Funds are two transactions:  a sale of shares of
one Fund and the purchase of shares of another.  In general, the same rules and
procedures that apply to sales and purchases apply to exchanges.  There are,
however, additional factors you should keep in mind while making or considering
an exchange:

 .  You should carefully read the Prospectus for the Fund into which you wish to
   exchange.
 .  Every exchange involves selling Fund shares and that sale may produce a
   capital gain or loss for federal income tax purposes.
 .  If you are making an initial investment into a new Fund through an exchange,
   you must exchange at least the minimum first purchase amount of the Fund you
   are redeeming, unless your balance has fallen below that amount due to market
   conditions.
 .  Any exchange between Funds you already own must meet the minimum redemption
   and subsequent purchase amounts for the Funds involved.
 .  Exchanges between Class B shares and the Wells Fargo Money Market Fund Class
   B shares will not trigger the CDSC. The new shares will continue to age
   according to their original schedule while in the new Fund and will be
   charged the CDSC applicable to the original shares upon redemption. Exchanges
   into Money Market Fund Class B shares are subject to certain restrictions in
   addition to those described above.
 .  Exchanges from any share class to a money market fund can only be re-
   exchanged for the original share class.
 .  In order to discourage excessive Fund transaction expenses that must be borne
   by other shareholders, we reserve the right to limit or reject exchange
   orders. Generally, we will notify you 60 days in advance of any changes in
   your exchange privileges.
 .  You may make exchanges between like share classes. You may also exchange from
   Class A or Class C shares to any non-institutional money market fund.

Additional Services and Other Information

Automatic Programs:
These programs help you conveniently purchase and/or redeem shares each month.
Call Investor Services 1-800-222-8222 for more information.

 .  Systematic Purchase Plan - With this program, you can regularly purchase
   shares of a Wells Fargo Fund with money automatically transferred from a
   linked bank account. Simply select the Fund you would like to purchase,
   specify an amount of at least $100, and tell us the day of the month you
   would like the money invested. If you do not specify a date, we will transfer
   the money and invest in shares of the Fund you select on or about the 25th
   day of the month.

 .  Systematic Exchange Plan - With this program, you can regularly exchange
   shares of a Wells Fargo Fund you own for shares of another Wells Fargo Fund.
   The exchange amount must be at least $100, and the exchange will take place
   on or about the 25th of each month. See the "Exchanges" section of this
   prospectus for the conditions that apply to your shares. This feature may not
   be available for certain types of accounts.

 .  Systematic Withdrawal Plan - With this program, you can regularly redeem
   shares and receive the proceeds by check or by transfer to a linked bank
   account. Simply specify an amount of at least $100 and we will sell your
   shares equal to that amount on or about the 25th of each month. To
   participate in this program, you:
   .  must have a Fund account value at $10,000 or more;
   .  must have your distributions reinvested; and
   .  may not simultaneously participate in the Systematic Purchase Plan.

It generally takes about ten days to establish a plan once we have received your
instructions.  It generally takes about five days to change or cancel
participation in a plan.  We automatically cancel your program if the linked
bank account your specified is closed.

Dividend and Capital Gain Distributions Options
The Funds in this Prospectus pay dividends monthly and make capital gains
distributions annually.

We offer the following distribution options:

 .  Automatic Reinvestment Option - Lets you buy new shares of the same class of
   the Fund that generated the distributions. The new shares are purchased at
   NAV generally on the day the income is paid. This option is automatically
   assigned to your account unless you specify another plan.

 .  Check Payment Option - Allows you to receive checks for distributions mailed
   to your address of record or to another name and address which you have
   specified in written, signature guaranteed instructions. If checks remain
   uncashed for six months or are undeliverable by the Post Office, we will
   reinvest the distributions at the earliest date possible.

Two Things to Keep In Mind About Distributions
Remember, distributions have the effect of reducing the NAV per share by the
amount distributed.  Also, distributions on new shares shortly after purchase
would be in effect a return of capital, although the distribution may still be
taxable to you.

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus.  The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder.  It
is not intended as a substitute for careful tax planning.  You should consult
your tax advisor about your specific tax situation.  Federal income tax
considerations are discussed further in the Statement of Additional Information.

Dividends distributed from the Tax-Free Income Fund and Municipal Money Market
Fund attributable to their net interest income from tax-exempt securities will
not be subject to federal income tax.  Dividends distributed from these and the
other Funds attributable to their income from other investments and net short-
term capital gain (generally, the excess of net short-term capital gains over
net long-term capital losses) will be taxable to you as ordinary income.
Corporate shareholders may be able to deduct a portion of their dividends when
determining their taxable income.

We will pass on to you any net capital gain (generally the excess of net long-
term capital gains over net short-term capital losses) earned by a Fund as a
capital gain distribution.  In general, these distributions will be taxable to
you as long-term capital gains which may qualify for taxation at preferential
rates in the hands of non-corporate shareholders.  Any distribution that is not
from net investment income, short term capital gains, or net capital gain may be
characterized as a return of capital to shareholders.

Summary Of Important Risks

This section summarizes important risks that are common to all of the Funds
described in this Prospectus, and important risks that relate specifically to
particular Funds.  Both are important to your investment choice.  Additional
information about these and other risks is included in the individual Fund
Descriptions later in this Prospectus, under General Investment Risks beginning
on page __ and in the Funds' Statement of Additional Information.  An investment
in a Fund is not a deposit of Wells Fargo Bank and is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.

Common Risks for the Funds

Equity Securities.  The Funds invest in equity securities, which are subject to
equity market risk.  This is the risk that stock prices will fluctuate and can
decline and reduce the value of a Fund's portfolio.  Certain types of stock and
certain individual stocks selected for a Fund's portfolio may underperform or
decline in value more than the overall market.  As of the date of this
Prospectus, the equity markets, as measured by the S&P 500 Index and other
commonly used indexes, are trading at or close to record levels.  There can be
no guarantee that these levels will continue.  The Funds that invest in smaller
companies, in foreign companies (including investments made through American
Depositary Receipts ("ADRs") and similar instruments), and in emerging markets
are subject to additional risks, including less liquidity and greater price
volatility.  A Fund's investment in foreign companies and emerging markets are
also subject to special risks associated with international investing, including
currency, political, regulatory and diplomatic risks.

Fixed-Income Securities.  The Funds may invest in debt instruments, such as
notes and bonds, which are subject to credit risk and interest rate risk.
Credit risk is the possibility that an issuer of an instrument will be unable to
make interest payments or repay principal.  Changes in the financial strength of
an issuer or changes in the credit rating of a security may affect its value.
Interest rate risk is the risk that interest rates may increase, which will
reduce the resale value of instruments in a Fund's portfolio.  Debt instruments
with longer maturities are generally more sensitive to interest rate changes
than those with shorter maturities.  Changes in market interest rates do not
affect the rate payable on debt instruments held in a Fund, unless the
instrument has adjustable or variable rate features, which can reduce interest
rate risk.  Changes in market interest rates may also extend or shorten the
duration of certain types of instruments, such as asset-backed securities,
thereby affecting their value and the return on your investment.

Fund-Specific Risks

The U.S. Government does not directly or indirectly insure or guarantee the
performance of the Fund.  Mortgage-backed securities are subject to the risk
that homeowners may refinance existing mortgages to take advantage of lower
rates.  Such "prepayment" result in an early return of principal that is then
reinvested at what is likely to be a lower yield.  Investments in foreign
markets may also present special risks, including currency, political,
diplomatic, regulatory and liquidity risks.

Performance History

The Funds in this Prospectus will commence operations in September 1999.  No
performance information is given for the Funds because they will have been in
operation for less than one year.

Diversified Bond Fund

Investment Objective
The Fund's investment objective is to provide total return by diversifying its
investments among different fixed income investment styles.

Investment Policies
The Fund uses a "multi-style" approach designed to reduce the price and return
volatility of the Fund and to provide more consistent returns.  The Fund's
portfolio combines the different fixed income investment styles of 3 portfolios
- - Managed Fixed Income style, Strategic Value Bond style, and Positive Return
style.

Permitted Investments
Under normal market conditions, we invest in:
 .  debt securities;
 .  U.S. Government obligations
 .  mortgage or asset-backed securities
 .  dollar-denominated debt of U.S. branches of foreign banks.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, either to maintain liquidity
or for short-term defensive purposes when we believe it is in the best interests
of shareholders to do so.  During such periods, the Fund may not achieve its
investment objective.

Important Risk Factors
To manage its exposure to different types of investments, a Fund may enter into
interest rate, currency and mortgage (or other asset) swap agreements and may
purchase and sell interest rate "caps," "floors," and "collars."

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

Core/Gateway Structure
The Diversified Bond Fund is a "gateway" fund in a "core/gateway" structure.  In
this structure, a "gateway" fund invests all of its assets in various "core"
portfolios that assist the Fund to achieve its investment objective.  Gateway
funds investing in various core portfolios can enhance their investment
opportunities and reduce their expenses through sharing the costs of managing a
large pool of assets.  References to the investment activities of the Fund also
refer to the core portfolios in which it invests.

Government, except the U.S. Treasury, and may not invest more than 10% of its
total assets in the securities of any other issuer.

The Fund only purchases Investment Grade securities.  The Fund invests in debt
obligations with maturities (or average life in the case of mortgage-backed and
similar securities) ranging from overnight to 12 years and seeks to maintain an
average dollar-weighted portfolio maturity of between 2 and 5 years.

Important Risk Factors
To manage its exposure to different types of investments, a Fund may enter into
interest rate, currency and mortgage (or other asset) swap agreements and may
purchase and sell interest rate "caps," "floors," and "collars."

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

Core/Gateway Structure
The Fund is a "gateway" fund in a "core/gateway" structure.  In this structure,
a "gateway" fund invests all of its assets in a "core" portfolio that has a
substantially identical investment objective and substantially similar policies
as the gateway fund.  Gateway funds investing in the same core portfolio can
enhance their investment opportunities and reduce their expense ratios through
sharing the costs of managing a large pool of assets.  References to the
investment activities of the Fund also refer to the core portfolio.

Strategic Income Fund

Investment Objective
The Fund's investment objective is to provide a combination of current income
and capital appreciation by diversifying investments in bonds, other fixed-
income investments, and stocks.

Investment Policies
The Fund is designed for investors seeking to invest in fixed income securities
with limited exposure to equity securities.  The Fund emphasizes stability of
principal.  The Fund currently invests in 15 Portfolios.

The Fund invests the fixed income portion of its portfolio in:  the same 3
Portfolios as Diversified Bond Fund; in Stable Income Portfolio; and Money
Market Portfolio.  The blending of multiple fixed income investment styles is
intended to reduce the price and return volatility of, and provide more
consistent returns within, the fixed income portion of the Fund's investments.
The equity portion of the Fund's portfolio uses the 5 different equity
investment styles of Diversified Equity Fund.  The blending of multiple equity
investment styles is intended to reduce the risk associated with the use of a
single style, which may move in and out of favor during the course of a market
cycle.

Permitted Investments
Under normal market conditions, we invest in:

 .  corporate government bonds;
 .  a wide range of income producing securities;
 .  debt securities that are below investment grade including high risk
   securities; and
 .  foreign issues.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, either to maintain liquidity
or for short-term defensive purposes when we believe it is in the best interests
of shareholders to do so.  We may also, for defensive purposes, invest without
limit in cash, short-term debt and equity securities of U.S. companies when we
believe it is in the best interests of shareholders to do so.  During these
periods, the Fund may not achieve its objective of current income and capital
appreciation.

Important Risk Factors
The percentage of the Fund's assets invested in different styles of Portfolios
may temporarily deviate from the Fund's current allocation due to changes in
market values.  The Advisor will effect transactions periodically to reestablish
the current allocation.

You should consider the Summary of Important Risks on page __, the General
Investment Risks beginning on page __, and the specific risks listed above.
They are all important to your investment choice.

Core/Gateway Structure
The Strategic Income Fund is a "gateway" fund in a "core/gateway" structure.  In
this structure, a "gateway" fund invests all of its assets in various "core"
portfolios that assist the Fund to achieve its investment objective.  Gateway
funds investing in various core portfolios can enhance their investment
opportunities and reduce their expenses through sharing the costs of managing a
large pool of assets.  References to the investment activities of the Fund also
refer to the core portfolios in which it invests.

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds.  Certain common risks are identified in the
Summary of Important Risks on page ___.  Other risks of mutual fund investing
include the following:

 .  Unlike bank deposits such as CDs or savings accounts, mutual funds are not
   insured by the FDIC.
 .  We cannot guarantee that we will meet our investment objectives.

 .  We do not guarantee the performance of a Fund, nor can we assure you that the
   market value of your investment will not decline. We will not "make good" any
   investment loss you may suffer, nor can anyone we contract with to provide
   certain services, such as selling agents or investment advisors, offer or
   promise to make good any such losses.

 .  Share prices -- and therefore the value of your investment -- will increase
   and decrease with changes in the value of the underlying securities and other
   investments.  This is referred to as price volatility.

 .  Investing in any mutual fund, including those deemed conservative, involves
   risk, including the possible loss of any money you invest.
 .  An investment in a single Fund, by itself, does not constitute a complete
   investment plan.

 .  The Funds that invest in smaller companies, foreign companies (including
   investments made through ADRs and similar instruments), and in emerging
   markets are subject to additional risks, including less liquidity and greater
   price volatility. A Fund's investment in foreign and emerging markets may
   also be subject to special risks associated with international trade,
   including currency, political, regulatory and diplomatic risk.

 .  The Funds may invest a portion of their assets in U.S. Government
   obligations. It is important to recognize that the U.S. Government does not
   guarantee the market value or current yield of those obligations. Not all
   U.S. Government obligations are backed by the full faith and credit of the
   U.S. Treasury, and the U.S. Government's guarantee does not extend to the
   Funds themselves.

 .  The Funds may also use certain derivative instruments, such as options or
   futures contracts. The term "derivatives" covers a wide number of
   investments, but in general it refers to any financial instrument whose
   value is derived, at least in part, from the price of another security or a
   specified index, asset or rate. Some derivatives may be more sensitive to
   interest rate changes or market moves, and some may be susceptible to changes
   in yields or values due to their structure or contract terms.

 .  The Funds may temporarily hold assets in cash or in money market instruments,
   including U.S. Government obligations, shares of other mutual funds and
   repurchase agreements, or make other short-term investments, either to
   maintain liquidity or for short-term defensive purposes when we believe it is
   in the best interests of shareholders to do so. To the extent a Fund's assets
   are so invested, they may cause a Fund to not achieve its investment
   objective. This practice is expected to have limited, if any, effect on the
   Funds' pursuit of their objectives over the long term.

 .  The Funds may invest a portion of their assets in U.S. Government
   obligations, such as securities issued or guaranteed by the Government
   National Mortgage Association (GNMAs"), the Federal National Mortgage
   Association ("FNMAs") and the Federal Home Loan Mortgage Corporation
   ("FHLMCs"). Each are mortgage-backed securities representing partial
   ownership of a pool of residential mortgage loans. A "pool" or group of such
   mortgages is assembled and, after being approved by the issuing or
   guaranteeing entity, is offered to investors through securities dealers.
   Mortgage-backed securities are subject to prepayment and extensive risk,
   which can alter the maturity of the securities and also reduce the rate of
   return on the portfolio. Collateralized mortgage obligations ("CMOs")
   typically represent principal-only and interest-only portions of such
   securities and are subject to increased interest-rate and credit risk.

                                       12
<PAGE>

 .  The market value of lower-rated debt securities and unrated securities of
   comparable quality that the Funds may invest in tends to reflect individual
   developments affecting the issuer to a greater extent than the market value
   of higher-rated securities, which react primarily to fluctuations in the
   general level of interest rates. Lower-rated securities also tend to be more
   sensitive to economic conditions than higher-rated securities. These lower-
   rated debt securities are considered by the rating agencies, on balance, to
   be predominantly speculative with respect to the issuer's capacity to pay
   interest and repay principal. These securities generally involve more credit
   risk than securities in higher-rating categories. Even securities rated "BBB"
   by S&P or by Moody's ratings which are considered investment-grade, possess
   some speculative characteristics.

Investment practices and risk levels are carefully monitored.  Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Fund and a table showing some of the
additional investment practices that each Fund may use and the risks associated
with them.  Additional information about these practices is available in the
Statement of Additional Information.

Counter-Party Risk--The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule.  If an issuer does default,
the affected security could lose all of its value, or be renegotiated at a lower
interest rate or principal amount.  Affected securities might also lose
liquidity.  Credit risk also includes the risk that a party in a transaction may
not be able to complete the transaction as agreed.

Currency Risk--The risk that a change in the exchange rate between U.S. dollars
and a foreign currency may reduce the value of an investment made in a security
denominated in that foreign currency.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value of
liquidity of investments in either country.

Emerging Market Risk--The risk that the emerging market, as defined in the
glossary, may be more sensitive to certain economic changes.  For example,
emerging market countries are often dependent on international trade and are
therefore often vulnerable to recessions in other countries.  They may have
obsolete financial systems, have volatile currencies and may be more sensitive
than more mature markets to a variety of economic factors.  Emerging market
securities may also be less liquid than securities of more developed countries
and could be difficult to sell, particularly during a market downturn.

Experience Risk--The risk presented by a new or innovative security.  The risk
is that insufficient experience exists to forecast how the security's value
might be affected by various economic conditions:

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security.  Generally, when interest rates increase, the value of
a debt security decreases.  The effect is usually more pronounced for securities
with longer dates to maturity.

Leverage Risk--The risk that a practice may increase a Fund's exposure to market
risk, interest rate risk or other risks by, in effect, increasing assets
available for investment.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

                                       13
<PAGE>

Market Risk--The risk that the value of a stock, bond or other security will be
reduced by market activity.  This is a basic risk associated with all
securities.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

Prepayment Risk--The risk that consumers will accelerate their prepayment of
mortgage loans or other receivables, which can shorten the maturity of a
mortgage-backed or other asset-backed security, and reduce portfolio's rate of
return.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.  Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Year 2000 Risk--The Funds' principal service providers have advised the Funds
that they are working on the necessary changes to their computer systems to
avoid any system failure based on an inability to distinguish the year 2000 from
the year 1900, and that they expect their systems to be adapted in time.  There
can, of course, be no assurance of success.  In addition, the companies or
entities in which the Funds invest also could be adversely impacted by the Year
2000 issue, especially foreign entities, which may be less prepared for Year
2000.  The extent of such impact cannot be predicted.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund.  You should also
see the Statement of Additional Information for additional information about the
investment practices and risks particular to each Fund.

Organization and Management of the Funds

A number of different entities provide services to the Funds. This section shows
how the Funds are organized, lists the entities that perform different services,
and explains how these service providers are compensated. Further information is
available in the Statement of Additional Information for the Funds.

About Wells Fargo Funds Trust
Wells Fargo Funds Trust (the "Trust") was organized as a Delaware business trust
on March 10, 1999. The Board of Trustees of the Trust supervises each Fund's
activities, monitors its contractual arrangements with various service providers
and decides upon matters of general policy.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds. The holding company of Wells Fargo Bank, the investment advisor to the
Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998. Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one or more Stagecoach
and/or Norwest Advantage Funds. One of these predecessor funds is expected to be
the "accounting survivor," which means that its performance and financial
statement history will be assumed by the Wells Fargo Funds Trust Fund. The
succession transactions are conditioned on shareholder approval by the
shareholders of the various Stagecoach and Norwest Advantage Funds. The Table on
page __ identifies the expected accounting survivors.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund class paid on an annual basis for the
services described.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund class paid on an annual basis for the
services described.

The Investment Advisor
Wells Fargo Bank provides portfolio management and fundamental security analysis
services as the advisor for each of the Funds. Wells Fargo Bank, founded in
1852, is the oldest bank in the western United States and is one of the largest
banks in the United States. Wells Fargo Bank is a wholly owned subsidiary of
Wells Fargo & Company, a national bank holding company. As of December 31, 1998,
Wells Fargo Bank and its affiliates managed over $202 billion in assets. For
providing these services for the Stable Income Fund, Wells Fargo is entitled to
receive a fee of .50% of the Fund's average annual net assets.

The Diversified Bond and Strategic Income Funds are gateway Funds that invest in
various core portfolios. Wells Fargo Bank is entitled to receive an investment
advisory fee of .25% of each Fund's average annual net assets for investment
advisory services, including the determination of the asset allocation of each
Fund's investments in various core portfolios. Wells Fargo Bank also acts as the
Advisor to, and is entitled to receive a fee from, each core portfolio. The
total amount of investment advisory fees paid to Wells Fargo Bank as a result of
a Fund's investments varies depending on the Fund's allocation of assets among
the various core portfolios. The charts below lists the advisory fees charged at
the core level for each core portfolio in which the Funds invest.

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:
 .    As with all mutual fund investments, the price you pay to purchase shares
     or the price you receive when you redeem shares is not determined until
     after a request has been received in proper form.
 .    We determine the Net Asset Value ("NAV") of each class of the Funds' shares
     each business day at 1:00 p.m. (Pacific Time). We determine the NAV by
     subtracting the Fund class's liabilities from its total assets, and then
     dividing the result by the total number of outstanding shares of that
     class. Each Fund's assets are generally valued at current market prices.
     See the Statement of Additional Information for further disclosure.
 .    We process requests to buy or sell shares of the Funds each business day as
     of the close of regular trading on the New York Stock Exchange ("NYSE"),
     which is usually 1:00 p.m. (Pacific time). If the markets close early, the
     Funds may close early and may value their shares at earlier times under
     these circumstances. Any request we receive in proper form before these
     times is processed the same day. Requests we receive after the cutoff times
     are processed the next business day.
 .    The funds are open for business on each day the NYSE is open for business.
     NYSE holidays include New Year's Day, Martin Luther King, Jr. Day,
     President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
     Thanksgiving Day and Christmas Day. When any holiday falls on a weekend,
     the NYSE typically is closed on the weekday immediately before or after
     such holiday.

Minimum Investments:
 .    Institutional Shares require a mimimum initial investment of $2,000,000 and
     have no minimum subsequent investment requirement.

We may waive the minimum for Funds you purchase through certain retirement,
benefit and pension plans, through certain packaged investment products, or for
certain classes of shareholders as permitted by the SEC. Check the specific
disclosure statements and applications for the program through which you intend
to invest.

Your Account (Cont'd)

How to Buy Shares
You can open a Fund account and buy Fund shares through an Institution through
which you have established a Customer Account. Investors interested in
purchasing Institutional shares of the Funds should contact an account
representative at their Institution and should understand the following:

 .    Share purchases are made through a Customer Account at an Institution in
     accordance with the terms of the Customer Account involved;
 .    Institutions are usually the holders of record of Institutional shares held
     through Customer Accounts and maintain records reflecting their customers'
     beneficial ownership of the shares;
 .    Institutions are responsible for transmitting their customers' purchase and
     redemption orders to the Funds and for delivering required payment on a
     timely basis;
 .    The exercise of voting rights and the delivery of shareholder
     communications from the Fund is governed by the terms of the Customer
     Account involved; and
 .    Institutions may charge their customers account fees and may receive fees
     from us with respect to investments their customers have made with the
     Funds. See "Organization and Management of the Funds" for further details
     about these fees.

Selling Shares
Institutional shares must be redeemed in accordance with the account agreement
governing your Customer Account at the Institution. Please read the Customer
Account agreement with your Institution for rules governing selling shares.

- --------------------------------------------------------------------------------
GENERAL NOTES FOR SELLING SHARES
- --------------------------------------------------------------------------------
We determine the NAV of the funds each day as of the close of regular trading on
the NYSE, which is generally 1:00 PM (Pacific time). Redemption proceeds are
usually wired to the redeeming Institution the following business day.
- --------------------------------------------------------------------------------
Redemption proceeds are usually wired to the redeeming Institution the following
business day.
- --------------------------------------------------------------------------------
We will process requests to sell shares at the first NAV calculated after a
request in proper form is received. Requests received before the cutoff times
are processed on the same business day.
- --------------------------------------------------------------------------------
If your purchased shares through a packaged investment product or retirement
plan, read the directions for selling shares provided by the product or plan.
There maybe special requirements that supersede the directions in this
Prospectus.
- --------------------------------------------------------------------------------
We reserve the right to delay payment of a redemption so that we may be
reasonably certain that investments made by check or Systematic Purchase Plan
have been collected. Payments of redemptions also may be delayed under
extraordinary circumstances or as permitted by the SEC in order to protect
remaining shareholders.
- --------------------------------------------------------------------------------
Generally, we pay redemption requests in cash, unless the redemption request is
for more than $250,000 or 1% of the net assets of the Fund by a single
shareholder over any ninety-day period. If a request for a redemption is over
these limits, it may be to the detriment of existing shareholders to pay such
redemption in cash. Therefore, we may pay all or part of the redemption in
securities of equal value.
- --------------------------------------------------------------------------------

Exchanges

Exchanges between Wells Fargo Funds are two transactions: a sale of shares of
one Fund and the purchase of shares of another. In general, the same rules and
procedures that apply to sales and purchases apply to exchanges. There are,
however, additional factors you should keep in mind while making or considering
an exchange:

 .    You should carefully read the Prospectus for the Fund into which you wish
     to exchange.
 .    Every exchange involves selling Fund shares and that sale may produce a
     capital gain or loss for federal income tax purposes.
 .    If you are making an initial investment into a new Fund through an
     exchange, you must exchange at least the minimum first purchase amount of
     the Fund you are redeeming, unless your balance has fallen below that
     amount due to market conditions.
 .    Any exchange between Funds you already own must meet the minimum redemption
     and subsequent purchase amounts for the Funds involved.
 .    Exchanges from any share class to a money market fund can only be re-
     exchanged for the original share class.
 .    In order to discourage excessive Fund transaction expenses that must be
     borne by other shareholders, we reserve the right to limit or reject
     exchange orders. Generally, we will notify you 60 days in advance of any
     changes in your exchange privileges.
 .    You may make exchanges only between like share classes.

Additional Services and Other Information

Automatic Programs:
These programs help you conveniently purchase and/or redeem shares each month.
Call Investor Services 1-800-222-8222 for more information.

 .    Systematic Purchase Plan - With this program, you can regularly purchase
     shares of a Wells Fargo Fund with money automatically transferred from a
     linked bank account. Simply select the Fund you would like to purchase,
     specify an amount of at least $100, and tell us the day of the month you
     would like the money invested. If you do not specify a date, we will
     transfer the money and invest in shares of the Fund you select on or about
     the 25th day of the month.

 .    Systematic Exchange Plan - With this program, you can regularly exchange
     shares of a Wells Fargo Fund you own for shares of another Wells Fargo
     Fund. The exchange amount must be at least $100, and the exchange will take
     place on or about the 25th of each month. See the "Exchanges" section of
     this prospectus for the conditions that apply to your shares. This feature
     may not be available for certain types of accounts.

 .    Systematic Withdrawal Plan - With this program, you can regularly redeem
     shares and receive the proceeds by check or by transfer to a linked bank
     account. Simply specify an amount of at least $100 and we will sell your
     shares equal to that amount on or about the 25th of each month. To
     participate in this program, you:

     .    must have a Fund account value at $10,000 or more;
     .    must have your distributions reinvested; and
     .    may not simultaneously participate in the Systematic Purchase Plan.

It generally takes about ten days to establish a plan once we have received your
instructions. It generally takes about five days to change or cancel
participation in a plan. We automatically cancel your program if the linked bank
account your specified is closed.

Dividend and Capital Gain Distributions Options
The Funds in this Prospectus pay dividends monthly and make capital gains
distributions annually.

We offer the following distribution options:

 .    Automatic Reinvestment Option - Lets you buy new shares of the same class
     of the Fund that generated the distributions. The new shares are purchased
     at NAV generally on the day the income is paid. This option is
     automatically assigned to your account unless you specify another plan.

 .    Check Payment Option - Allows you to receive checks for distributions
     mailed to your address of record or to another name and address which you
     have specified in written, signature guaranteed instructions. If checks
     remain uncashed for six months or are undeliverable by the Post Office, we
     will reinvest the distributions at the earliest date possible.

Two Things to Keep In Mind About Distributions
Remember, distributions have the effect of reducing the NAV per share by the
amount distributed.  Also, distributions on new shares shortly after purchase
would be in effect a return of capital, although the distribution may still be
taxable to you.

                                       24

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus. The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder. It
is not intended as a substitute for careful tax planning. You should consult
your tax advisor about your specific tax situation. Federal income tax
considerations are discussed further in the Statement of Additional Information.

Dividends distributed from the Tax-Free Income Fund and Municipal Money Market
Fund attributable to their net interest income from tax-exempt securities will
not be subject to federal income tax. Dividends distributed from these and the
other Funds attributable to their income from other investments and net short-
term capital gain (generally, the excess of net short-term capital gains over
net long-term capital losses) will be taxable to you as ordinary income.
Corporate shareholders may be able to deduct a portion of their dividends when
determining their taxable income.

We will pass on to you any net capital gain (generally the excess of net long-
term capital gains over net short-term capital losses) earned by a Fund as a
capital gain distribution. In general, these distributions will be taxable to
you as long-term capital gains which may qualify for taxation at preferential
rates in the hands of non-corporate shareholders. Any distribution that is not
from net investment income, short term capital gains, or net capital gain may be
characterized as a return of capital to shareholders.

                             TABLE OF PREDECESSORS

the holders of a majority (as

                                       1
<PAGE>

defined in the Investment Company Act of 1940, as amended (the "1940 Act")) of
the outstanding voting securities of such Fund.

The Funds may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of a Fund's investments in that industry would equal 25% of
the current value of the Fund's total assets, provided that there is no
limitation with respect to investment in securities issued or guaranteed by the
United States Government, its agencies or instrumentalities;

     (2)  purchase securities of any issuer if, as a result, with respect to 75%
of a Fund's total assets, more than 5% of the value of its total assets would be
invested in the securities of any one issuer or, with respect to 100% of its
assets, the Fund's ownership would be more than 10% of the outstanding voting
securities of such issuer.  This policy does not restrict a Fund's ability to
invest in securities issued or guaranteed by the U.S. Government, its agencies
and instrumentalities; or to invest substantially all of its assets in  the
portfolio of one or more open-end management investment companies pursuant to
Section 12 of the 1940 Act and the rules thereunder;

     (3)  borrow money except to the extent permitted by the 1940 Act, and the
rules, regulations and exemptions thereunder;

     (4)  issue senior securities  except to the extent permitted by the 1940
Act, and the rules, regulations and exemptions thereunder;

     (5)  make loans to other parties if, as a result, the aggregate value of
such loans would exceed one-third of a Fund's total assets.  For the purposes of
this limitation, entering into repurchase agreements, lending securities and
acquiring any debt securities are not deemed to be the making of loans;

     (6)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer and the later disposition of such securities in
accordance with a Fund's investment program may be deemed to be an underwriting;

     (7)  purchase or sell real estate unless acquired as a result of ownership
of securities or other instruments (but this shall not prevent the Fund from
investing in securities or other instruments backed by real estate or securities
of companies engaged in the real estate business); nor

     (8)  purchase or sell physical commodities unless acquired as a result of
ownership of securities or other instruments (but this shall not prevent the
Funds from purchasing or selling options and futures contracts, or from
investing in securities or other instruments backed by physical commodities.

     Non-Fundamental Investment Policies
     -----------------------------------

     Each Fund has adopted the following non-fundamental policies which may be
changed by a vote of a majority of the Trustees of the Trust or at any time
without approval of such Fund's shareholders.

     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of the 1940 Act, the rules thereunder, and
any orders obtained thereunder now or in the future. Funds in a master/feeder or
core/gateway structure, such as the Income Equity Fund, generally invest in the
securities of one or more open-end management investment companies pursuant to
various provisions of the 1940 Act. Other investment companies in which the
Funds invest can be expected to charge fees for operating expenses, such as
investment advisory and administration fees, that would be in addition to those
charged by a Fund.

     (2)  Each Fund may not invest or hold more than 15% of the Fund's net
assets in illiquid securities. For this purpose, illiquid securities include,
among others, (a) securities that are illiquid by virtue of the absence of a
readily available market or legal or contractual restrictions on resale, (b)
fixed time deposits that are subject to withdrawal penalties and that have
maturities of more than seven days, and (c) repurchase agreements not terminable
within seven days.

     (3)  Each Fund may invest in futures or options contracts regulated by the
CFTC for (i) bona fide hedging purposes within the meaning of the rules of the
CFTC and (ii) for other purposes if, as a result, no more than 5% of the Fund's
net assets would be invested in initial margin and premiums (excluding amounts
"in-the-money") required to establish the contracts.

          Each Fund (i) will  not hedge more than [50%] of its total assets by
selling futures contracts, buying put options, and writing call options (so
called "short positions"),  (ii) will not buy futures contracts or write put
options whose underlying value exceeds [25%] of the Fund's total assets, and
(iii) will not buy call options with a value exceeding [5%] of the Fund's total
assets.

     (4)  Each Fund may lend securities from its portfolio to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) up to
the limits established by and under the 1940 Act, including any exemptive relief
obtained thereunder, which limits are currently generally one-third of a Fund's
total assets. Any such loans of portfolio securities will be fully
collateralized based on values that are marked to market daily. [A Fund will not
enter into any portfolio security lending arrangement having a duration of
longer than one year.]

     (5)  Each Fund may not make investments for the purpose of exercising
control or management. (Investments by the Fund in entities created under the
laws of foreign countries solely to facilitate investment in securities in that
country will not be deemed the making of investments for the purpose of
exercising control.)

     (6)  Each Fund may not purchase securities on margin (except for short-term
credits necessary for the clearance of transactions).

                                       3
<PAGE>

     (7)  Each Fund may not sell securities short, unless it owns or has the
right to obtain securities equivalent in kind and amount to the securities sold
short (short sales "against the box"), and provided that transactions in futures
contracts and options are not deemed to constitute selling securities short.

     (8)  Each Fund may not purchase interests, leases, or limited partnership
interests in oil, gas, or other mineral exploration or development programs.

        ADDITIONAL PERMITTED INVESTMENT ACTIVITIES AND ASSOCIATED RISKS

     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

     Asset-Backed Securities
     -----------------------

     The Corporate Bond, Income Plus and Variable Rate Government Funds may
invest in various types of asset-backed securities. Asset-backed securities are
securities that represent an interest in an underlying security. The asset-
backed securities in which the Funds invest may consist of undivided fractional
interests in pools of consumer loans or receivables held in trust. Examples
include certificates for automobile receivables (CARS) and credit card
receivables (CARDS). Payments of principal and interest on these asset-backed
securities are "passed through" on a monthly or other periodic basis to
certificate holders and are typically supported by some form of credit
enhancement, such as a surety bond, limited guaranty, or subordination. The
extent of credit enhancement varies, but usually amounts to only a fraction of
the asset-backed security's par value until exhausted. Ultimately, asset-backed
securities are dependent upon payment of the consumer loans or receivables by
individuals, and the certificate holder frequently has no recourse to the entity
that originated the loans or receivables. The actual maturity and realized yield
will vary based upon the prepayment experience of the underlying asset pool and
prevailing interest rates at the time of prepayment. Asset-backed securities are
relatively new instruments and may be subject to greater risk of default during
periods of economic downturn than other instruments. Also, the secondary market
for certain asset-backed securities may not be as liquid as the market for other
types of securities, which could result in a Fund experiencing difficulty in
valuing or liquidating such securities. These Funds may also invest in
securities backed by pools of mortgages. The investments are described under the
heading "Mortgage-Related Securities."

     Bank Obligations
     ----------------

     The Funds may invest in bank obligations, including certificates of
deposit, time deposits, bankers' acceptances and other short-term obligations of
domestic banks, foreign subsidiaries of domestic banks, foreign branches of
domestic banks, and domestic and foreign branches of foreign banks, domestic
savings and loan associations and other banking institutions. With respect to
such securities issued by foreign branches of domestic banks, foreign
subsidiaries of domestic banks, and domestic and foreign branches of foreign
banks, a Fund may be subject to additional investment risks that are different
in some respects from those incurred by a Fund which invests only in debt
obligations of U.S. domestic issuers. Such risks include possible future
political and economic developments, the possible imposition of foreign
withholding taxes

                                       4
<PAGE>

on interest income payable on the securities, the possible establishment of
exchange controls or the adoption of other foreign governmental restrictions
which might adversely affect the payment of principal and interest on these
securities and the possible seizure or nationalization of foreign deposits. In
addition, foreign branches of U.S. banks and foreign banks may be subject to
less stringent reserve requirements and to different accounting, auditing,
reporting and recordkeeping standards than those applicable to domestic branches
of U.S. banks.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate. Time
deposits which may be held by a Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation ("FDIC"). Bankers' acceptances are
credit instruments evidencing the obligation of a bank to pay a draft drawn on
it by a customer. These instruments reflect the obligation both of the bank and
of the drawer to pay the face amount of the instrument upon maturity. The other
short-term obligations may include uninsured, direct obligations, bearing fixed,
floating- or variable-interest rates.

     Below Investment Grade Investments
     ----------------------------------

     The Corporate Bond and Income Plus Funds may invest in debt securities that
are in low or below investment grade categories, or are unrated or in default at
the time of purchase. Such debt securities have a much greater risk of default
(or in the case of bonds currently in default, of not returning principal) and
are more volatile than higher-rated securities of similar maturity. The value of
such debt securities will be affected by overall economic conditions, interest
rates, and the creditworthiness of the individual issuers. Additionally, these
lower rated debt securities may be less liquid and more difficult to value than
higher rated securities.

     Stocks of the smaller and medium-sized companies in which the Fund may
invest may be more volatile than larger company stocks. Investments in foreign
markets may also present special risks, including currency, political,
diplomatic, regulatory and liquidity risks.

     Bonds
     -----

     Certain of the debt instruments purchased by the Funds may be bonds. The
Funds invests no more than 25% in bonds that are below investment grade. A bond
is an interest-bearing security issued by a company or governmental unit. The
issuer of a bond has a contractual obligation to pay interest at a stated rate
on specific dates and to repay principal (the bond's face value) periodically or
on a specified maturity date. An issuer may have the right to redeem or "call" a
bond before maturity, in which case the investor may have to reinvest the
proceeds at lower market rates. The value of fixed-rate bonds will tend to fall
when interest rates rise and rise when interest rates fall. The value of
"floating-rate" or "variable-rate" bonds, on the other hand, fluctuate much less
in response to market interest rate movements than the value of fixed rate
bonds.

     Bonds may be senior or subordinated obligations. Senior obligations
generally have the first claim on a corporation's earnings and assets and, in
the event of liquidation, are paid before

                                       5
<PAGE>

subordinated debt. Bonds may be unsecured (backed only by the issuer's general
creditworthiness) or secured (also backed by specified collateral).

     Commercial Paper
     ----------------

     The Funds may invest in commercial paper (including variable amount master
demand notes) which refers to short-term, unsecured promissory notes issued by
corporations to finance short-term credit needs. Commercial paper is usually
sold on a discount basis and has a maturity at the time of issuance not
exceeding nine months. Variable amount master demand notes are demand
obligations which permit the investment of fluctuating amounts at varying market
rates of interest pursuant to arrangements between the issuer and a commercial
bank acting as agent for the payee of such notes whereby both parties have the
right to vary the amount of the outstanding indebtedness on the notes.
Investments by the Funds in commercial paper (including variable rate demand
notes and variable rate master demand notes issued by domestic and foreign bank
holding companies, corporations and financial institutions, as well as similar
instruments issued by government agencies and instrumentalities) will consist of
issues that are rated in one of the two highest rating categories by a
Nationally Recognized Ratings Organization ("NRRO").  Commercial paper may
include variable- and floating-rate instruments.

     Convertible Securities
     ----------------------

     The Corporate Bond and Income Plus Funds may invest in convertible
securities.  A convertible security is generally a debt obligation or preferred
stock that may be converted within a specified period of time into a certain
amount of common stock of the same or a different user.  A convertible security
provides a fixed-income stream and the opportunity, through its conversion
feature, to participate in the capital appreciation resulting from a market
price advance in its underlying common stock.  As with a straight fixed-income
security, a convertible security tends to increase in market value when interest
rates decline and decrease in value when interest rates rise.  Like a common
stock, the value of a convertible security also tends to increase as the market
value of the underlying stock rises, and it tends to decrease as the market
value of the underlying stock declines.  Because its value can be influenced by
both interest rate and market movements, a convertible security is not as
sensitive to interest rats as a similar fixed-income security, nor is it as
sensitive to changes in share price as its underlying stock.

     The creditworthiness of the issuer of a convertible security may be
important in determining the security's true value.  This is because the holder
of a convertible security will have recourse only to the issuer.  In addition, a
convertible security may be subject to redemption by the issuer, but only after
a specified date and under circumstances established at the time the security is
issued.

     While the Funds use the same criteria to rate a convertible debt security
that it uses to rate a more conventional debt security, a convertible preferred
stock is treated like a preferred stock for a Funds' financial reporting, credit
rating, and investment limitation purposes.  A preferred stock is subordinated
to all debt obligations in the event of insolvency, and an issuer's failure to
make a dividend payment is generally not an event of default entitling the
preferred shareholder to take action.  A preferred stock generally has no
maturity date, so that its market value is

                                       6
<PAGE>

dependent on the issuer's business prospects for an indefinite period of time.
In addition, distributions from preferred stock are dividends, rather than
interest payments, and are usually treated as such for corporate tax purposes.

     Derivative Securities
     ---------------------

     The Corporate Bond, Income Plus, Stable Income and Diversified Bond Funds
may invest in various instruments that may be considered "derivatives,"
including structured notes, bonds or other instruments with interest rates that
are determined by reference to changes in the value of other interest rates,
indices or financial indicators ("References") or the relative change in two or
more References.  Some derivative securities represent relatively recent
innovations in the bond markets, and the trading market for these instruments is
less developed than the markets for traditional types of debt instruments. It is
uncertain how these instruments will perform under different economic and
interest rate scenarios. Because certain of these instruments are leveraged,
their market values may be more volatile than other types of bonds and may
present greater potential for capital gain or loss.  Derivative securities and
their underlying instruments may experience periods of illiquidity, which could
cause a Fund to hold a security it might otherwise sell or could force the sale
of a security at inopportune times or for prices that do not reflect current
market value. The possibility of default by the issuer or the issuer's credit
provider may be greater for these structured and derivative instruments than for
other types of instruments.  As new types of derivative securities are developed
and offered to investors, the advisor will, consistent with the Funds'
investment objective, policies and quality standards, consider making
investments in such new types of derivative securities.

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds may purchase floating- and variable-rate obligations such as
demand notes and bonds. Variable-rate demand notes include master demand notes
that are obligations that permit a Fund to invest fluctuating amounts, which may
change daily without penalty, pursuant to direct arrangements between the Fund,
as lender, and the borrower. The interest rate on a floating-rate demand
obligation is based on a known lending rate, such as a bank's prime rate, and is
adjusted automatically each time such rate is adjusted. The interest rate on a
variable-rate demand obligation is adjusted automatically at specified
intervals. The issuer of such obligations ordinarily has a right, after a given
period, to prepay in its discretion the outstanding principal amount of the
obligations plus accrued interest upon a specified number of days' notice to the
holders of such obligations. Frequently, such obligations are secured by letters
of credit or other credit support arrangements provided by banks.

     There generally is no established secondary market for these obligations
because they are direct lending arrangements between the lender and borrower.
Accordingly, where these obligations are not secured by letters of credit or
other credit support arrangements, a Fund's right to redeem is dependent on the
ability of the borrower to pay principal and interest on demand. Such
obligations frequently are not rated by credit rating agencies and each Fund may
invest in obligations which are not so rated only if the Advisor determines that
at the time of investment the obligations are of comparable quality to the other
obligations in which such Fund may invest. The Advisor, on behalf of each Fund,
considers on an ongoing basis the creditworthiness of the issuers of the
floating- and variable-rate demand obligations in such

                                       7
<PAGE>

Fund's portfolio. No Fund will invest more than [15%] of the value of its total
net assets in floating- or variable-rate demand obligations whose demand feature
is not exercisable within seven days. Such obligations may be treated as liquid,
if an active secondary market exists. Floating- and variable-rate instruments
are subject to interest-rate risk and credit risk.

     The floating- and variable-rate instruments that the Funds may purchase
include certificates of participation in such instruments.

     Foreign Obligations and Securities
     ----------------------------------

     The Corporate Bond, Strategic Income and Variable Rate Government Funds may
invest up to 25% of its assets in high-quality, short-term debt obligations of
foreign branches of U.S. banks, U.S. branches of foreign banks and short-term
debt obligations of foreign governmental agencies that are denominated in and
pay interest in U.S. dollars. Investments in foreign obligations involve certain
considerations that are not typically associated with investing in domestic
obligations. There may be less publicly available information about a foreign
issuer than about a domestic issuer and the available information may be less
reliable. In addition, with respect to certain foreign countries, taxes may be
withheld at the source under foreign tax laws, and there is a possibility of
expropriation or confiscatory taxation, political or social instability or
diplomatic developments that could adversely affect investments in, the
liquidity of, and the ability to enforce contractual obligations with respect
to, securities of issuers located in those countries. The Funds may invest in
securities denominated in currencies other than the U.S. dollar and may
temporarily hold funds in bank deposits or other money market investments
denominated in foreign currencies. Therefore, the Funds may be affected
favorably or unfavorably by exchange control regulations or changes in the
exchange rate between such currencies and the dollar. Changes in foreign
currency exchange rates influence values within a Fund from the perspective of
U.S. investors. The rate of exchange between the U.S. dollar and other
currencies is determined by the forces of supply and demand in the foreign
exchange markets. These forces are affected by the international balance of
payments and other economic and financial conditions, government intervention,
speculation and other factors.

     The Funds may enter into forward currency exchange contracts ("forward
contracts") to attempt to minimize the risk to the Funds from adverse changes in
the relationship between currencies or to enhance income [check].  A forward
contract is an obligation to buy or sell a specific currency for an agreed price
at a future date which is individually negotiated and is privately traded by
currency traders and their customers.  The Funds will either cover a position in
such a transaction or maintain, in a segregated account with their custodian
bank, cash or high-grade marketable money market securities having an aggregate
value equal to the amount of any such commitment until payment is made.

     Forward Commitment, When-Issued and Delayed-Delivery Transactions
     -----------------------------------------------------------------

     The Funds may purchase or sell securities on a when-issued or delayed
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time. Delivery and payment on
such transaction normally take place within 120 days after the date of the
commitment to purchase. Securities purchased or sold on a when-issued, delayed-
delivery or forward commitment basis involve a risk of loss if the value of the
security

                                       8
<PAGE>

to be purchased declines, or the value of the security to be sold increases,
before the settlement date. The Funds will establish a segregated account in
which they will maintain cash, U.S. Government obligations or other high-quality
debt instruments in an amount at least equal in value to each such Fund's
commitments to purchase when-issued securities. If the value of these assets
declines, a Fund will place additional liquid assets in the account on a daily
basis so that the value of the assets in the account is equal to the amount of
such commitments.

     Illiquid Securities
     -------------------

     The Funds may invest in securities not registered under the Securities Act
of 1933, as amended (the "1933 Act") and other securities subject to legal or
other restrictions on resale. Because such securities may be less liquid than
other investments, they may be difficult to sell promptly at an acceptable
price. Delay or difficulty in selling securities may result in a loss or be
costly to a Fund.  Each Fund may invest up to 15% of its net assets in illiquid
securities.

     Interest Rate Protection Transactions
     -------------------------------------

     To manage its exposure to different types of investments, the Stable Income
and Diversified Bond Funds may enter into interest rate, currency and mortgage
(or other asset) swap agreements and may purchase and sell interest rate "caps,"
"floors" and "collars." In a typical interest rate swap agreement, one party
agrees to make regular payments equal to a floating interest rate on a specific
amount in return for payments equal to a fixed interest rate on the same amount
for a specified period. In a cap or floor, one party agrees, usually in return
for a fee, to make payments under particular circumstances. A collar entitles
the purchaser to receive payments to the extent a specified interest rate falls
outside an agreed upon range.

     A Fund expects to enter into interest rate protection transactions to
preserve a return or spread on a particular investment or portion of its
portfolio or to protect against any increase in the price of securities it
anticipates purchasing at a later date. The Funds intend to use these
transactions as a hedge and not as a speculative investment.

     Loans of Portfolio Securities
     -----------------------------

     Each Fund may lend its portfolio securities to brokers, dealers and
financial institutions, provided: (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at least equal to the
current market value of the securities loaned; (2) such Fund may at any time
call the loan and obtain the return of the securities loaned within five
business days; (3) such Fund will receive any interest or dividends paid on the
loaned securities; and (4) the aggregate market value of securities loaned will
not at any time exceed the limits established by the 1940 Act.

     A Fund will earn income for lending its securities because cash collateral
pursuant to these loans will be invested in short-term money market instruments.
In connection with lending securities, a Fund may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide additional collateral. In either case, a Fund could experience delays
in recovering securities or collateral or could lose all or part of the value of
the loaned securities.  Although voting rights, or

                                       9
<PAGE>

rights to consent, attendant to securities on loan pass to the borrower, such
loans may be called at any time and will be called so that the securities may be
voted by a Fund if a material event affecting the investment is to occur. A Fund
may pay a portion of the interest or fee earned from securities lending to a
borrower or a placing broker. Borrowers and placing brokers may not be
affiliated, directly or indirectly with Wells Fargo Bank, Stephens or any of
their affiliates.

     Mortgage-Related Securities
     ---------------------------

     The Funds may invest in mortgage-related securities.  Mortgage pass-through
securities are securities representing interests in "pools" of mortgages in
which payments of both interest and principal on the securities are made
monthly, in effect "passing through" monthly payments made by the individual
borrowers on the residential mortgage loans which underlie the securities (net
of fees paid to the issuer or guarantor of the securities).  Payment of
principal and interest on some mortgage pass-through securities (but not the
market value of the securities themselves) may be guaranteed by the full faith
and credit of the U.S. Government or its agencies or instrumentalities.
Mortgage pass-through securities created by non- government issuers (such as
commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers) may be supported
by various forms of insurance or guarantees, including individual loan, title,
pool and hazard insurance, and letters of credit, which may be issued by
governmental entities, private insurers or the mortgage poolers.

     Prepayment Risk.  The stated maturities of mortgage-related securities may
be shortened by unscheduled prepayments of principal on the underlying
mortgages.  Therefore, it is not possible to predict accurately the average
maturity of a particular mortgage-related security .  Variations in the
maturities of mortgage-related securities will affect the yield of the Fund.
Early repayment of principal on mortgage-related securities may expose a Fund to
a lower rate of return upon reinvestment of principal. Also, if a security
subject to prepayment has been purchased at a premium, in the event of
prepayment the value of the premium would be lost. Like other fixed-income
securities, when interest rates rise, the value of a mortgage-related security
generally will decline; however, when interest rates decline, the value of
mortgage-related securities with prepayment features may not increase as much as
other fixed-income securities.

     Collateralized Mortgage Obligations ("CMOs") and Adjustable Rate Mortgages
("ARMs").  The Funds may also invest in investment grade CMOs.  CMOs may be
collateralized by whole mortgage loans but are more typically collateralized by
portfolios of mortgage pass-through securities guaranteed by the Government
National Mortgage Association ("GNMA"), the Federal Home Loan Mortgage
Corporation ("FHLMC") or Federal National Mortgage Association ("FNMA"). CMOs
are structured into multiple classes, with each class bearing a different stated
maturity. Payments of principal, including prepayments, are first returned to
investors holding the shortest maturity class; investors holding the longer
maturity classes receive principal only after the first class has been retired.
As new types of mortgage-related securities are developed and offered to
investors, the Advisor will, consistent with the Fund's investment objective,
policies and quality standards, consider making investments in such new types of
mortgage-related securities.

     The Funds each may invest in ARMs issued or guaranteed by the GNMA, FNMA or
the FHLMC.  The full and timely payment of principal and interest on GNMA ARMs
is guaranteed by

                                       10
<PAGE>

GNMA and backed by the full faith and credit of the U.S. Government. FNMA also
guarantees full and timely payment of both interest and principal, while FHLMC
guarantees full and timely payment of interest and ultimate payment of
principal. FNMA and FHLMC ARMs are not backed by the full faith and credit of
the United States. However, because FNMA and FHLMC are government-sponsored
enterprises, these securities are generally considered to be high quality
investments that present minimal credit risks. The yields provided by these ARMs
have historically exceeded the yields on other types of U.S. Government
securities with comparable maturities, although there can be no assurance that
this historical performance will continue.

     The mortgages underlying ARMs guaranteed by GNMA are typically insured or
guaranteed by the Federal Housing Administration, the Veterans Administration or
the Farmers Home Administration, while those underlying ARMs issued by FNMA or
FHLMC are typically conventional residential mortgages which are not so insured
or guaranteed, but which conform to specific underwriting, size and maturity
standards.

     The interest rates on the mortgages underlying the ARMs and some of the
CMOs in which the Funds may invest generally are readjusted at periodic
intervals ranging from one year or less to several years in response to changes
in a predetermined commonly-recognized interest rate index. The adjustable rate
feature should reduce, but will not eliminate, price fluctuations in such
securities, particularly when market interest rates fluctuate. The net asset
value of a Funds' shares may fluctuate to the extent interest rates on
underlying mortgages differ from prevailing market interest rates during interim
periods between interest rate reset dates. Accordingly, investors could
experience some loss if they redeem their shares of a Fund or if the Funds sells
these portfolio securities before the interest rates on the underlying mortgages
are adjusted to reflect prevailing market interest rates. The holder of ARMs and
CMOs are also subject to repayment risk.

     The Funds will not invest in CMOs that, at the time of purchase, are "high-
risk mortgage securities" as defined in the then current Federal Financial
Institutions Examination Council Supervisory Policy Statement on Securities
Activities.  High-risk mortgage securities are generally those with long
durations or those which are likely to be more sensitive to interest-rate
fluctuations.

     Mortgage Participation Certificates. The Short-Intermediate U.S. Government
Income Fund and Intermediate Government Income Fund also may invest in the
following types of FHLMC mortgage pass-through securities. FHLMC issues two
types of mortgage pass-through securities: mortgage participation certificates
("PCs") and guaranteed mortgage certificates ("GMCs"). PCs resemble GNMA
certificates in that each PC represents a pro rata share of all interest and
principal payments made and owed on the underlying pool of mortgages. GMCs also
represent a pro rata interest in a pool of mortgages. These instruments,
however, pay interest semiannually and return principal once a year in
guaranteed minimum payments. These mortgage pass-through securities differ from
bonds in that principal is paid back by the borrower over the length of the loan
rather than returned in a lump sum at maturity. They are called "pass-through"
securities because both interest and principal payments, including prepayments,
are passed through to the holder of the security. PCs and GMCs are both subject
to prepayment risk.

     Other Investment Companies
     --------------------------

                                       11
<PAGE>

     The Funds may invest in shares of other open-end management investment
companies, up to the limits prescribed in Section 12(d) of the 1940 Act.  Under
the 1940 Act, a Fund's investment in such securities currently is limited to,
subject to certain exceptions, (i) 3% of the total voting stock of any one
investment company, (ii) 5% of such Fund's net assets with respect to any one
investment company and (iii) 10% of such Fund's net assets in aggregate.  Other
investment companies in which the Funds invest can be expected to charge fees
for operating expenses, such as investment advisory and administration fees,
that would be in addition to those charged by the Funds.

     Repurchase Agreements
     ---------------------

     Each Fund may enter into repurchase agreements, wherein the seller of a
security to a Fund agrees to repurchase that security from a Fund at a mutually
agreed upon time and price.  A Fund may enter into repurchase agreements only
with respect to securities that could otherwise be purchased by such Fund.  All
repurchase agreements will be fully collateralized at 102% based on values that
are marked to market daily.  The maturities of the underlying securities in a
repurchase agreement transaction may be greater than twelve months, although the
maximum term of a repurchase agreement will always be less than twelve months.
If the seller defaults and the value of the underlying securities has declined,
a Fund may incur a loss.  In addition, if bankruptcy proceedings are commenced
with respect to the seller of the security, the Funds' disposition of the
security may be delayed or limited.

     A Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 15% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities.  A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Trustees and that are not affiliated with the investment advisor.  The
Funds may participate in pooled repurchase agreement transactions with other
funds advised by Wells Fargo Bank.

     Stripped Securities
     -------------------

     The Funds may purchase Treasury receipts, securities of government-
sponsored enterprises (GSEs), and other "stripped" securities that evidence
ownership in either the future interest payments or the future principal
payments on U.S. Government and other obligations.  The stripped securities the
Funds may purchase are issued by the U.S. Government (or a U.S. Government
agency or instrumentality) or by private issuers such as banks, corporations and
other institutions at a discount to their face value.  The Funds will not
purchase stripped mortgage-backed securities ("SMBS").  The stripped securities
purchased by the Funds generally are structured to make a lump-sum payment at
maturity and do not make periodic payments of principal or interest.  Hence, the
duration of these securities tends to be longer and they are therefore more
sensitive to interest rate fluctuations than similar securities that offer
periodic payments over time.  The stripped securities purchased by the Funds are
not subject to prepayment or extension risk.

     The Funds may purchase participations in trusts that hold U.S. Treasury
securities (such as TIGRs and CATS) or other obligations where the trust
participations evidence ownership in either

                                       12
<PAGE>

the future interest payments or the future principal payments on the
obligations. These participations are normally issued at a discount to their
"face value," and can exhibit greater price volatility than ordinary debt
securities because of the way in which their principal and interest are returned
to investors. Investments by the Funds in such participations will not exceed 5%
of the value of the Funds' total assets.

     Reverse Repurchase Agreements
     -----------------------------

     The Funds intend to limit their borrowings (including reverse repurchase
agreements) during the current fiscal year to not more than 10% of net assets.
At the time a Fund enters into a reverse repurchase agreement (an agreement
under which a Fund sells their portfolio securities and agrees to repurchase
them at an agreed-upon date and price), it will place in a segregated custodial
account liquid assets such as U.S. Government securities or other liquid high-
grade debt securities having a value equal to or greater than the repurchase
price (including accrued interest) and will subsequently monitor the account to
ensure that such value is maintained.  Reverse repurchase agreements involve the
risk that the market value of the securities sold by the Funds may decline below
the price at which the Funds are obligated to repurchase the securities. Reverse
repurchase agreements are considered to be borrowings under the 1940 Act.

     Unrated Investments
     -------------------

     The Corporate Bond, Income Plus and Diversified Bond Funds may purchase
instruments that are not rated if, in the opinion of the Advisor, such
obligations are of investment quality comparable to other rated investments that
are permitted to be purchased by such Fund.  After purchase by a Fund, a
security may cease to be rated or its rating may be reduced below the minimum
required for purchase by the Fund.  Neither event will require a sale of such
security by the Fund.  To the extent the ratings given by Moodys or S&P may
change as a result of changes in such organizations or their rating systems, a
Fund will attempt to use comparable ratings as standards for investments in
accordance with the investment policies contained in its Prospectus and in this
SAI.  The ratings of Moodys and S&P are more fully described in the SAI
Appendix.

     U.S. Government Obligations
     ---------------------------

     The Funds may invest in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Obligations").
Payment of principal and interest on U.S. Government Obligations (i) may be
backed by the full faith and credit of the United States (as with U.S. Treasury
bills and GNMA certificates) or (ii) may be backed solely by the issuing or
guaranteeing agency or instrumentality itself (as with FNMA notes). In the
latter case investors must look principally to the agency or instrumentality
issuing or guaranteeing the obligation for ultimate repayment, which agency or
instrumentality may be privately owned. There can be no assurance that the U.S.
Government will provide financial support to its agencies or instrumentalities
where it is not obligated to do so. In addition, U.S. Government Obligations are
subject to fluctuations in market value due to fluctuations in market interest
rates. As a general matter, the value of debt instruments, including U.S.
Government Obligations, declines when market interest rates increase and rises
when market interest rates decrease. Certain types of U.S.

                                       13
<PAGE>

Government Obligations are subject to fluctuations in yield or value due to
their structure or contract terms.

     Zero Coupon Bonds
     -----------------

     The Dividend Bond, Stable Income and Strategic Income Funds may invest in
zero coupon bonds.  Zero coupon bonds are securities that make no periodic
interest payments, but are instead sold at discounts from face value.  The buyer
of such a bond receives the rate of return by the gradual appreciation of the
security, which is redeemed at face value on a specified maturity date.  Because
zero coupon bonds bear no interest, they are more sensitive to interest-rate
changes and are therefore more volatile.  When interest rates rise, the discount
to face value of the security deepens and the securities decrease more rapidly
in value, when interest rates fall, zero coupon securities rise more rapidly in
value because the bonds carry fixed interest rates that become more attractive
in a falling interest rate environment.

     Nationally Recognized Ratings Organizations
     -------------------------------------------

     The ratings of Moody's, S&P, Division of McGraw Hill, Duff & Phelps Credit
Rating Co., Fitch Investors Service, Inc. Thomson Bank Watch and IBCA Inc.
represent their opinions as to the quality of debt securities. It should be
emphasized, however, that ratings are general and not absolute standards of
quality, and debt securities with the same maturity, interest rate and rating
may have different yields while debt securities of the same maturity and
interest rate with different ratings may have the same yield.  Subsequent to
purchase by the Funds, an issue of debt securities may cease to be rated or its
rating may be reduced below the minimum rating required for purchase by the
Funds.  The Advisor will consider such an event in determining whether the Fund
involved should continue to hold the obligation.

                                  MANAGEMENT

(collectively the "Fund Complex"). Trustees are compensated annually by the
Trust and by all the registrants in each fund complex they serve beginning
September 17, 1999, and beginning March 26, 1999, receive a per-meeting fee of
$250. Trustees also are reimbursed for all out-of-pocket expenses relating to
attendance at board meetings. Each of the Trustees and Officers of the Trust
serves in the identical capacity as trustees and/or officers of each registered
open-end management investment company in the Fund Complex. The Trustees are
compensated by other companies and trusts within a fund complex for their
services as directors/trustees to such companies and trusts. Currently the
Trustees do not receive any retirement benefits or deferred compensation from
the Trust or any other member of each fund complex.

     As of the date of this SAI, Trustees and Officers of the Trust as a group
beneficially owned less than 1% of the outstanding shares of the Trust.

     Investment Advisor.  Wells Fargo Bank provides investment advisory services
     ------------------
to the Funds.  As investment advisor, Wells Fargo Bank furnishes investment
guidance and policy direction in connection with the daily portfolio management
of the Funds. Wells Fargo Bank furnishes to the Trust's Board of Trustees
periodic reports on the investment strategy and performance of each Fund.  Wells
Fargo Bank provides the Funds with, among other things, money market security
and fixed-income research, analysis and statistical and economic data and
information concerning interest rate and securities markets trends, portfolio
composition, and credit conditions.

     As compensation for its advisory services, Well Fargo Bank is entitled to
receive a monthly fee at the annual rates indicated below of each Fund's average
daily net assets:

     General.  Each Fund's Advisory Contract will continue in effect for more
     -------
than two years from the effective date provided the continuance is approved
annually (i) by the holders of a majority of the respective Fund's outstanding
voting securities or by the Trust's Board of Trustees and (ii) by a majority of
the Trustees of the Trust who are not parties to the Advisory Contract or
"interested persons" (as defined in the 1940 Act) of any such party.  A Fund's
Advisory Contract may be terminated on 60 days' written notice by either party
and will terminate automatically if assigned.

     Investment Sub-Advisors.  Wells Fargo Bank has engaged Wells Capital
     -----------------------
Management ("WCM") to serve as Investment Sub-Advisor to the Corporate Bond,
Income Plus and Variable Rate Government Funds.  Subject to the direction of the
Trust's Board of Trustees and the overall supervision and control of Wells Fargo
Bank and the Trust, WCM makes recommendations regarding the investment and
reinvestment of the Funds' assets.  WCM furnishes to Wells Fargo Bank periodic
reports on the investment activity and performance of the Funds.  WCM also
furnishes such additional reports and information as Wells Fargo Bank and the
Trust's Board of Trustees and officers may reasonably request.

     As compensation for its sub-advisory services, WCM is entitled to receive a
monthly fee as follows:

     Portfolio Managers.
     ------------------

     [TO BE INSERTED]

     Administrator.  The Trust has retained Wells Fargo Bank as Administrator on
     -------------
behalf of each Fund. Under the Administration Agreement between Wells Fargo Bank
and the Trust, Wells Fargo Bank shall provide as administration services, among
other things: (i) general supervision of the Funds' operations, including
coordination of the services performed by each Fund's investment Advisor,
transfer agent, custodian, shareholder servicing agent(s), independent auditors
and legal counsel, regulatory compliance, including the compilation of
information for documents such as reports to, and filings with, the U.S.
Securities and Exchange Commission ("SEC") and state securities commissions; and
preparation of proxy statements and shareholder reports for each Fund; and (ii)
general supervision relative to the compilation of data required for the
preparation of periodic reports distributed to the Trust's officers and Board of
Trustees. Wells Fargo Bank also furnish office space and certain facilities
required for conducting the Funds' business together with ordinary clerical and
bookkeeping services. The Administrator is entitled to receive a fee of .15% of
average daily net assets on an annual basis.

     Distributor.  Stephens (the "Distributor"), located at 111 Center Street,
     -----------
Little Rock, Arkansas  72201, serves as the Distributor for the Funds.  Each
Fund has adopted a distribution plan (a "Plan") under Section 12(b) of the 1940
Act and Rule 12b-1 thereunder (the "Rule") for its Class B and Class C shares.
The Plan was adopted by the Trust's Board of Trustees, including a majority of
the Trustees who were not "interested persons" (as defined in the 1940 Act) of
the Funds and who had no direct or indirect financial interest in the operation
of the Plan or in any agreement related to the Plan (the "Non-Interested
Trustees").

     Under the Plan and pursuant to the related Distribution Agreement, the
Funds may pay Stephens up to .75% of the average daily net assets attributable
to the Class B and Class C shares of the Funds as compensation for distribution-
related services or as reimbursement for distribution-related expenses.

     The actual fee payable to the Distributor is determined, within such
limits, from time to time by mutual agreement between the Trust and the
Distributor and will not exceed the maximum sales charges payable by mutual
funds sold by members of the National Association of Securities Dealers, Inc.
("NASD") under the Conduct Rules of the NASD. The Distributor

                                       18
<PAGE>

may enter into selling agreements with one or more selling agents (which may
include Wells Fargo Bank and its affiliates) under which such agents may receive
compensation for distribution-related services from the Distributor, including,
but not limited to, commissions or other payments to such agents based on the
average daily net assets of Fund shares attributable to their customers. The
Distributor may retain any portion of the total distribution fee payable
thereunder to compensate it for distribution-related services provided by it or
to reimburse it for other distribution-related expenses.

     General.  The Plan will continue in effect from year to year if such
     -------
continuance is approved by a majority vote of both the Trustees of the Trust and
the Non-Interested Trustees.  Any Distribution Agreement related to the Plan
also must be approved by such vote of the Trustees and the Non-Interested
Trustees.  Such Agreement will terminate automatically if assigned, and may be
terminated at any time, without payment of any penalty, by a vote of a majority
of the outstanding voting securities of the relevant class of the Fund or by
vote of a majority of the Non-Interested Trustees on not more than 60 days'
written notice.  The Plan may not be amended to increase materially the amounts
payable thereunder without the approval of a majority of the outstanding voting
securities of the Fund, and no material amendment to the Plan may be made except
by a majority of both the Trustees of the Trust and the Non-Interested Trustees.

     The Plan requires that the Treasurer of the Trust shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Plan.  The Rule also
requires that the selection and nomination of Trustees who are not "interested
persons" of the Trust be made by such disinterested Trustees.

     Wells Fargo Bank, an interested person (as that term is defined in Section
2(a)(19) of the 1940 Act) of the Trust, acts as a selling agent for the Funds'
shares pursuant to selling agreements with Stephens authorized under the Plan.
As a selling agent, Wells Fargo Bank has an indirect financial interest in the
operation of the Plans.  The Board of Trustees has concluded that the Plan is
reasonably likely to benefit the Funds and their shareholders because the Plan
authorize the relationships with selling agents, including Wells Fargo Bank,
that have previously developed distribution channels and relationships with the
retail customers that the Funds are designed to serve.  These relationships and
distribution channels are believed by the Board to provide potential for
increased Fund assets and ultimately corresponding economic efficiencies (i.e.,
lower per-share transaction costs and fixed expenses) that are generated by
increased assets under management.

     Shareholder Servicing Agent.  The Funds have approved a Servicing Plan for
     ---------------------------
the Class A, Class B and Class C shares of the Funds, as applicable, and have
entered into related shareholder servicing agreements with financial
institutions, including Wells Fargo Bank. Under the agreements, Shareholder
Servicing Agents (including Wells Fargo Bank) agree to perform, as agents for
their customers, administrative services, with respect to Fund shares, which
include aggregating and transmitting shareholder orders for purchases, exchanges
and redemptions; maintaining shareholder accounts and records; and providing
such other related services as the Trust or a shareholder may reasonably
request. For providing shareholder services, a Servicing Agent is entitled to a
fee from the applicable Fund, on an annualized basis, of 0.25% of the average
daily net assets of the class of shares owned of record or beneficially by the
customers of the Servicing Agent during the period for which payment is being
made. The Servicing Plan and

related forms of shareholder servicing agreements were approved by the Trust's
Board of Trustees and provide that a Fund shall not be obligated to make any
payments under such Plans or related Agreements that exceed the maximum amounts
payable under the Conduct Rules of the NASD.

     General.  The Servicing Plan will continue in effect from year to year if
     -------
such continuance is approved by a majority vote of the Trustees of the Trust,
including a majority of the Trustees who are not "interested periods" (as
defined in the 1940 Act) of the Funds ("Non-Interested Trustees").  Any form of
Servicing Agreement related to the Servicing Plan also must be approved by such
vote of the Trustees and Non-Interested Trustees.  Servicing Agreements may be
terminated at any time, without payment of any penalty, by vote of a majority of
the Board of Trustees, including a majority of the Non-Interested Trustees.  No
material amendment to the Servicing Plan or related Servicing Agreements may be
made except by a majority of both the Trustees of the Trust and the Non-
Interested Trustees.

     The Servicing Plan requires that the Administrator shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Servicing Plan.

     Custodian.  Norwest Bank Minnesota, N.A. ("Norwest Bank") acts as Custodian
     ---------
for each Fund. The Custodian, among other things, maintains a custody account or
accounts in the name of each Fund, receives and delivers all assets for each
Fund upon purchase and upon sale or maturity, collects and receives all income
and other payments and distributions on account of the assets of each Fund, and
pays all expenses of each Fund.  For its services as Custodian, Norwest Bank is
entitled to receive a fee of .02% of the average daily net assets of each Fund.

     Fund Accountant.  Forum Financial Services, Inc. acts as Fund Accountant
     ---------------
for the Funds.  The Fund Accountant, among other things, computes net asset
values on a daily basis and performance calculations on a regular basis and as
requested by the Funds.  For providing such services, Forum is entitled to
receive a fee of [___.]

     Transfer and Dividend Disbursing Agent.  State Street Bank, acting through
     --------------------------------------
its affiliate Boston Financial Data Services ("BFDS"), acts as Transfer and
Dividend Disbursing Agent for the Funds.  For providing such services, BFDS is
entitled to receive a per-account fee of [.04% of the average daily net assets
of each such account on an annual basis].

                           PERFORMANCE CALCULATIONS

     The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

                                       20

     Performance information for a Fund or Class of shares in a Fund may be
useful in reviewing the performance of such Fund or Class of shares and for
providing a basis for comparison with investment alternatives.  The performance
of a Fund and the performance of a Class of shares in a Fund, however, may not
be comparable to the performance from investment alternatives because of
differences in the foregoing variables and differences in the methods used to
value portfolio securities, compute expenses and calculate performance.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

     Average Annual Total Return:  The Funds may advertise certain total return
     ---------------------------
information.  As and to the extent required by the SEC, an average annual
compound rate of return ("T") is computed by using the redeemable value at the
end of a specified period ("ERV") of a hypothetical initial investment ("P")
over a period of years ("n") according to the following formula: P(1+T)/n/=ERV.

     Cumulative Total Return.  In addition to the above performance information,
     -----------------------
each Fund may also advertise the cumulative total return of the Fund.
Cumulative total return is based on the overall percentage change in value of a
hypothetical investment in the Fund, assuming all Fund dividends and capital
gain distributions are reinvested, without reflecting the effect of any sales
charge that would be paid by an investor, and is not annualized.

     Yield Calculations:  The Funds may, from time to time, include their yields
     ------------------
and effective yields in advertisements or reports to shareholders or prospective
investors.  Quotations of yield for the Funds are based on the investment income
per share earned during a particular seven-day or thirty-day period, less
expenses accrued during a period ("net investment income") and are computed by
dividing net investment income by the offering price per share on the last date
of the period, according to the following formula:

                          YIELD = 2[(a - b + 1)/6/ - 1]
                                     -----
                                      Cd

     where a = dividends and interest earned during the period; b = expenses
accrued for the period (net of reimbursements); c = the average daily number of
shares of each class outstanding during the period that were entitled to receive
dividends; and d = the maximum offering price per share each class of shares on
the last day of the period.

     Effective Yield:  Effective yields for the Funds are based on the change in
     ---------------
the value of a hypothetical investment (exclusive of capital changes) over a
particular thirty-day period, less a pro-rata share of each Fund's expenses
accrued over that period (the "base period"), and stated as a percentage of the
investment at the start of the base period (the "base period return").  The base
period return is then annualized multiplying by 365/30, with the resulting yield
figure carried to at least the nearest hundredth of one percent.  "Effective
yield" for the Funds assumes that all dividends received during the period have
been reinvested.  Calculation of "effective yield" begins with the same "base
period return" used in the calculation of yield, which is then annualized to
reflect weekly compounding pursuant to the following formula:

         Effective Thirty-Day Yield = [Base Period Return +1)365/30]-1

                                       21
<PAGE>

     Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown. Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.  In connection with communicating its yields or total return to
current or prospective shareholders, these figures may also be compared to the
performance of other mutual funds tracked by mutual fund rating services or to
unmanaged indices which may assume reinvestment of dividends but generally do
not reflect deductions for administrative and management costs.

     The yields for each class of shares will fluctuate from time to time,
unlike bank deposits or other investments that pay a fixed yield for a stated
period of time, and do not provide a basis for determining future yields since
they are based on historical data. Yield is a function of portfolio quality,
composition, maturity and market conditions as well as the expenses allocated to
a Fund or to a particular class of a Fund.

     In addition, investors should recognize that changes in the net asset
values of shares of each class of a Fund will affect the yield of the respective
class of shares for any specified period, and such changes should be considered
together with such class' yield in ascertaining such class' total return to
shareholders for the period. Yield information for each class of shares may be
useful in reviewing the performance of the class of shares and for providing a
basis for comparison with investment alternatives. The yield of each class of
shares, however, may not be comparable to the yields from investment
alternatives because of differences in the foregoing variables and differences
in the methods used to value portfolio securities, compute expenses and
calculate yield.

     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Trust may quote the performance or price-
earning ratio of a Fund or a Class of in advertising and other types of
literature as compared with the performance of the S&P Index, the Dow Jones
Industrial Average, the Lehman Brothers 20+ Treasury Index, the Lehman Brothers
5-7 Year Treasury Index, Donoghue's Money Fund Averages, Real Estate Investment
Averages (as reported by the National Association of Real Estate Investment
Trusts), Gold Investment Averages (provided by the World Gold Council), Bank
Averages (which is calculated from figures supplied by the U.S. League of
Savings Institutions based on effective annual rates of interest on both
passbook and certificate accounts), average annualized certificate of deposit
rates (from the Federal Reserve G-13 Statistical Releases or the Bank Rate
Monitor), the Salomon One Year Treasury Benchmark Index, the Consumer Price
Index (as published by the U.S. Bureau of Labor Statistics), other managed or
unmanaged indices or performance data of bonds, municipal securities, stocks or
government securities (including data provided by Ibbotson Associates), or by
other services, companies, publications or persons who monitor mutual funds on
overall performance or other criteria.  The S&P Index and the Dow Jones
Industrial Average are unmanaged indices of selected common stock prices.  The
performance of a Fund or a class also may be compared to that of other mutual
funds having similar objectives.  This comparative performance could be
expressed as a ranking prepared by Lipper Analytical Services, Inc., CDA
Investment Technologies, Inc., Bloomberg Financial Markets or Morningstar, Inc.,
independent services which monitor the performance of mutual funds.  The Funds'
performance will be calculated by relating net asset value per share of each
class at the beginning of a stated period to the net asset value of the
investment, assuming reinvestment of all gains distributions paid, at the end of
the period.  The

                                       22
<PAGE>

Funds' comparative performance will be based on a comparison of yields, as
described above, or total return, as reported by Lipper, Survey Publications,
Donoghue or Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a class of shares with the performance of a Fund's
competitors. Of course, past performance cannot be a guarantee of future
results.  The Trust also may include, from time to time, a reference to certain
marketing approaches of the Distributor, including, for example, a reference to
a potential shareholder being contacted by a selected broker or dealer. General
mutual fund statistics provided by the Investment Trust Institute may also be
used.

     The Trust also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
each class of shares of a Fund: (i) the Consumer Price Index may be used to
assess the real rate of return from an investment in each class of shares of a
Fund; (ii) other government statistics, including, but not limited to, The
Survey of Current Business, may be used to illustrate investment attributes of
each class of shares of a Fund or the general economic, business, investment, or
financial environment in which a Fund operates; (iii) the effect of tax-deferred
compounding on the investment returns of each class of shares of a Fund or on
returns in general, may be illustrated by graphs, charts, etc., where such
graphs or charts would compare, at various points in time, the return from an
investment in each class of shares of the Fund (or returns in general) on a tax-
deferred basis (assuming reinvestment of capital gains and dividends and
assuming one or more tax rates) with the return on a taxable basis; and (iv) the
sectors or industries in which the Fund invests may be compared to relevant
indices of stocks or surveys (e.g., S&P Industry Surveys) to evaluate the
historical performance or current or potential value of each class of shares of
a Fund with respect to the particular industry or sector.

     The Trust also may use, in advertisements and other types of literature,
information and statements: (1) showing that bank savings accounts offer a
guaranteed return of principal and a fixed rate of interest, but no opportunity
for capital growth; and (2) describing Wells Fargo Bank, and its affiliates and
predecessors, as one of the first investment managers to advise investment
accounts using asset allocation and index strategies.  The Trust also may
include in advertising and other types of literature information and other data
from reports and studies prepared by the Tax Foundation, including information
regarding federal and state tax levels and the related "Tax Freedom Day."

     The Trust also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by an NRSRO, such as Standard Poor's
Corporation. Such rating would assess the creditworthiness of the investments
held by a Fund.  The assigned rating would not be a recommendation to purchase,
sell or hold a Fund's shares since the rating would not comment on the market
price of a Fund's shares or the suitability of a Fund for a particular investor.
In addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to a Fund or its investments. The Trust may compare the performance of each
class of shares of a Fund with other investments which are assigned ratings by
NRSROs. Any such comparisons may be useful to investors who wish to compare each
class' past performance with other rated investments.

     From time to time, a Fund may use the following statements, or variations
thereof, in advertisements and other promotional materials:  "Wells Fargo Bank,
as a Shareholder Servicing

                                       23
<PAGE>

Agent for the Wells Fargo Funds Trust, provides various services to its
customers that are also shareholders of the Funds. These services may include
access to Wells Fargo Funds Trust's account information through Automated Teller
Machines (ATMs), the placement of purchase and redemption requests for shares of
the Funds through ATMs and the availability of combined Wells Fargo Bank and
Wells Fargo Funds Trust account statements."

     The Trust also may disclose, in advertising and other types of literature,
information and statements that Wells Capital Management, Inc. (formerly, Wells
Fargo Investment Management) a subsidiary of Wells Fargo Bank, is listed in the
top 100 by Institutional Investor magazine in its July 1997 survey "America's
Top 300 Money Managers." This survey ranks money managers in several asset
categories.  The Trust also may disclose in advertising and other types of sales
literature the assets and categories of assets under management by the Trust's
investment Advisor and the total amount of assets and mutual fund assets managed
by Wells Fargo Bank.  As of August 1, 1998, Wells Fargo Bank and its affiliates
provided investment advisory services for approximately $63 billion of assets of
individuals, trusts, estates and institutions and $32 billion of mutual fund
assets.

     The Trust may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels"). Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees. Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely through Electronic Channels. Advertising and other
literature may disclose that Wells Fargo Bank may maintain Web sites, pages or
other information sites accessible through Electronic Channels (an "Information
Site") and may describe the contents and features of the Information Site and
instruct investors on how to access the Information Site and open a Sweep
Account. Advertising and other literature may also disclose the procedures
employed by Wells Fargo Bank to secure information provided by investors,
including disclosure and discussion of the tools and services for accessing
Electronic Channels. Such advertising or other literature may include
discussions of the advantages of establishing and maintaining a Sweep Account
through Electronic Channels and testimonials from Wells Fargo Bank customers or
employees and may also include descriptions of locations where product
demonstrations may occur. The Trust may also disclose the ranking of Wells Fargo
Bank as one of the largest money managers in the United States.

                       DETERMINATION OF NET ASSET VALUE

     Net asset value per share for each class of the Funds is determined as of
the close of regular trading (currently 1:00 p.m. Pacific time/3:00 p.m. Central
time) on each day the New York Stock Exchange ("NYSE") is open for business.
Expenses and fees, including advisory fees, are accrued daily and are taken into
account for the purpose of determining the net asset value of the Funds' shares.

     Securities of a Fund for which market quotations are available are valued
at latest prices.  Any security for which the primary market is an exchange is
valued at the last sale price on such exchange on the day of valuation or, if
there was no sale on such day, the latest bid price quoted on such day.  In the
case of other Fund securities, including U.S. Government securities but
excluding

                                       24
<PAGE>

money market instruments and debt securities maturing in 60 days or less, the
valuations are based on latest quoted bid prices. Money market instruments and
debt securities maturing in 60 days or less are valued at amortized cost.
Futures contracts will be marked to market daily at their respective settlement
prices determined by the relevant exchange. Prices may be furnished by a
reputable independent pricing service approved by the Trust's Board of Trustees.
Prices provided by an independent pricing service may be determined without
exclusive reliance on quoted prices and may take into account appropriate
factors such as institutional-size trading in similar groups of securities,
yield, quality, coupon rate, maturity, type of issue, trading characteristics
and other market data. All other securities and other assets of a Fund for which
current market quotations are not readily available are valued at fair value as
determined in good faith by the Trust's Board of Trustees and in accordance with
procedures adopted by the Trustees.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

     Shares of the Funds may be purchased on any day the Funds are open for
business.  Each Fund is open for business each day the NYSE is open for trading
(a "Business Day"). Currently, the NYSE is closed 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 a "Holiday"). When any
Holiday falls on a weekend, the NYSE typically is closed on the weekday
immediately before or after such Holiday.

     Payment for shares may, in the discretion of the advisor, be made in the
form of securities that are permissible investments for the Funds.  For further
information about this form of payment please contact Stephens. In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that such Fund receives satisfactory
assurances that (i) it will have good and marketable title to the securities
received by it; (ii) that the securities are in proper form for transfer to the
Fund; and (iii) adequate information will be provided concerning the basis and
other matters relating to the securities.

     Under the 1940 Act, the Funds may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit.  The Trust may also redeem shares involuntarily or make payment
for redemption in securities or other property if it appears appropriate to do
so in light of the Trust's responsibilities under the 1940 Act.  In addition,
the Trust may redeem shares involuntarily to reimburse the Fund for any losses
sustained by reason of the failure of a shareholder to make full payment for
shares purchased or to collect any charge relating to a transaction effected for
the benefit of a shareholder which is applicable to shares of a Fund as provided
from time to time in the Prospectus.

                            PORTFOLIO TRANSACTIONS

     The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities.  Subject to policies
established by the Trust's Board of

                                       25
<PAGE>

Trustees, Wells Fargo Bank is responsible for each Fund's portfolio decisions
and the placing of portfolio transactions. In placing orders, it is the policy
of the Trust to obtain the best results taking into account the dealer's general
execution and operational facilities, the type of transaction involved and other
factors such as the dealer's risk in positioning the securities involved. While
Wells Fargo Bank generally seeks reasonably competitive spreads or commissions,
the Funds will not necessarily be paying the lowest spread or commission
available.

     Purchases and sales of non-equity securities usually will be principal
transactions. Portfolio securities normally will be purchased or sold from or to
dealers serving as market makers for the securities at a net price. Each of the
Funds also will purchase portfolio securities in underwritten offerings and may
purchase securities directly from the issuer. Generally, municipal obligations
and taxable money market securities are traded on a net basis and do not involve
brokerage commissions. The cost of executing a Fund's portfolio securities
transactions will consist primarily of dealer spreads and underwriting
commissions. Under the 1940 Act, persons affiliated with the Trust are
prohibited from dealing with the Trust as a principal in the purchase and sale
of securities unless an exemptive order allowing such transactions is obtained
from the SEC or an exemption is otherwise available. The Fund may purchase
securities from underwriting syndicates of which Stephens or Wells Fargo Bank is
a member under certain conditions in accordance with the provisions of a rule
adopted under the 1940 Act and in compliance with procedures adopted by the
Board of Trustees.

     Wells Fargo Bank, as Investment Advisor to the Funds, may, in circumstances
in which two or more dealers are in a position to offer comparable results for a
Fund portfolio transaction, give preference to a dealer that has provided
statistical or other research services to Wells Fargo Bank. By allocating
transactions in this manner, Wells Fargo Bank is able to supplement its research
and analysis with the views and information of securities firms. Information so
received will be in addition to, and not in lieu of, the services required to be
performed by Wells Fargo Bank under the Advisory Contracts, and the expenses of
Wells Fargo Bank will not necessarily be reduced as a result of the receipt of
this supplemental research information. Furthermore, research services furnished
by dealers through which Wells Fargo Bank places securities transactions for a
Fund may be used by Wells Fargo Bank in servicing its other accounts, and not
all of these services may be used by Wells Fargo Bank in connection with
advising the Funds.

     Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
     ------------------
when Wells Fargo Bank deems portfolio changes appropriate. Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the best interests of the
Funds and their shareholders. The portfolio turnover rate is calculated by
dividing the lesser of purchases or sales of portfolio securities by the average
monthly value of the Fund's portfolio securities. For purposes of this
calculation, portfolio securities exclude all securities having a maturity when
purchased of one year or less. Portfolio turnover generally involves some
expenses to the Funds, including brokerage commissions or dealer mark-ups and
other transaction costs on the sale of securities and the reinvestment in other
securities. Portfolio turnover also can generate short-term capital gain tax
consequences. Portfolio turnover rate is not a limiting factor when Wells Fargo
Bank deems portfolio changes appropriate.

                                       26
<PAGE>

                                 FUND EXPENSES

     From time to time, Wells Fargo Bank and Stephens may waive fees from the
Funds in whole or in part.  Any such waiver will reduce expenses and,
accordingly, have a favorable impact on a Fund's performance.

     Except for the expenses borne by Wells Fargo Bank and Stephens, the Trust
bears all costs of its operations, including the compensation of its Trustees
who are not affiliated with Stephens or Wells Fargo Bank or any of their
affiliates; advisory, shareholder servicing and administration fees; payments
pursuant to any Plan; interest charges; taxes; fees and expenses of its
independent auditors, legal counsel, transfer agent and dividend disbursing
agent; expenses of redeeming shares; expenses of preparing and printing
Prospectuses (except the expense of printing and mailing Prospectuses used for
promotional purposes, unless otherwise payable pursuant to a Plan),
shareholders' reports, notices, proxy statements and reports to regulatory
agencies; insurance premiums and certain expenses relating to insurance
coverage; trade association membership dues; brokerage and other expenses
connected with the execution of portfolio transactions; fees and expenses of its
custodian, including those for keeping books and accounts and calculating the
net asset value per share of a Fund; expenses of shareholders' meetings;
expenses relating to the issuance, registration and qualification of a Fund's
shares; pricing services, organizational expenses and any extraordinary
expenses. Expenses attributable to the Fund are charged against Fund assets.
General expenses of the Trust are allocated among all of the funds of the Trust,
including the Funds, in a manner proportionate to the net assets of each Fund,
on a transactional basis, or on such other basis as the Trust's Board of
Trustees deems equitable.

                             FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes."  The Prospectuses of each Fund
describe generally the tax treatment of distributions by the Funds.  This
section of the SAI includes additional information concerning federal income
taxes.

     General.  The Trust intends to qualify each Fund as a regulated investment
     -------
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"), as long as such qualification is in the best interest of the Fund's
shareholders.  Each Fund will be treated as a separate entity for federal income
tax purposes.  Thus, the provisions of the Code applicable to regulated
investment companies generally will be applied to each Fund, rather than to the
Trust as a whole.  In addition, net capital gains, net investment income, and
operating expenses will be determined separately for each Fund.  As a regulated
investment company, each Fund will not be taxed on its net investment income and
capital gains distributed to its shareholders.

     Qualification as a regulated investment company under the Code requires,
among other things, that each Fund (a) derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including, but not limited to, gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) diversify

                                       27
<PAGE>

its holdings so that, at the end of each quarter of the taxable year, (i) at
least 50% of the market value of the Fund's assets is represented by cash,
government securities and other securities limited with respect to any one
issuer to an amount not greater than 5% of the Fund's assets and 10% of the
outstanding voting securities of such issuer, and (ii) not more than 25% of the
value of its assets is invested in the securities of any one issuer (other than
U.S. Government obligations and the securities of other regulated investment
companies), or in two or more issuers which the Fund controls and which are
determined to be engaged in the same or similar trades or businesses.

     The Funds also must distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income (which, for this
purpose, includes net short-term capital gains) earned in each taxable year.  In
general, these distributions must actually or be deemed to be made in the
taxable year.  However, in certain circumstances, such distributions may be made
in the 12 months following the taxable year.  Furthermore, distributions
declared in October, November or December of one taxable year and paid by
January 31 of the following taxable year will be treated as paid by December 31
of the first taxable year.  The Funds intend to pay out substantially all of
their net investment income and net realized capital gains (if any) for each
year.

     Excise Tax.  A 4% nondeductible excise tax will be imposed on each Fund
     ----------
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

     Taxation of Fund Investments.  Except as provided herein, gains and losses
     ----------------------------
on the sale of portfolio securities by a Fund will generally be capital gains
and losses.  Such gains and losses will ordinarily be long-term capital gains
and losses if the securities have been held by the Fund for more than one year
at the time of disposition of the securities.

     Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by a Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

     If an option granted by a Fund lapses or is terminated through a closing
transaction, such as a repurchase by the Fund of the option from its holder, the
Fund will realize a short-term capital gain or loss, depending on whether the
premium income is greater or less than the amount paid by the Fund in the
closing transaction.  Some realized capital losses may be deferred if they
result from a position which is part of a "straddle," discussed below.  If
securities are sold by the Fund pursuant to the exercise of a call option
written by it, the Fund will add the premium received to the sale price of the
securities delivered in determining the amount of gain or loss on the sale.  If
securities are purchased by a Fund pursuant to the exercise of a put option
written by it, such Fund will subtract the premium received from its cost basis
in the securities purchased.

     The amount of any gain or loss realized by a Fund on closing out a
regulated futures contract will generally result in a realized capital gain or
loss for federal income tax purposes. Regulated futures contracts held at the
end of each fiscal year will be required to be "marked to market" for federal
income tax purposes pursuant to Section 1256 of the Code.  In this regard, they
will be deemed to have been sold at market value. Sixty percent (60%) of any net
gain or loss recognized on these deemed sales, and sixty percent (60%) of any
net realized gain or loss from any actual sales, will generally be treated as
long-term capital gain or loss, and the remainder will be treated as short-term
capital gain or loss.  Transactions that qualify as designated hedges are
excepted from the "mark-to-market" rule and the "60%/40%" rule.

     Under Section 988 of the Code, a Fund generally will recognize ordinary
income or loss to the extent that gain or loss realized on the disposition of
portfolio securities is attributable to changes in foreign currency exchange
rates.  In addition, gain or loss realized on the disposition of a foreign
currency forward contract, futures contract, option or similar financial
instrument, or of foreign currency itself, will generally be treated as ordinary
income or loss.  The Funds will attempt to monitor Section 988 transactions,
where applicable, to avoid adverse Federal income tax impact.

     Offsetting positions held by a Fund involving certain financial forward,
futures or options contracts may be considered, for tax purposes, to constitute
"straddles."  "Straddles" are defined to include "offsetting positions" in
actively traded personal property.  The tax treatment of "straddles" is governed
by Section 1092 of the Code which, in certain circumstances, overrides or
modifies the provisions of Section 1256.  If a Fund were treated as entering
into "straddles" by engaging in certain financial forward, futures or option
contracts, such straddles could be characterized as "mixed straddles" if the
futures, forwards, or options comprising a part of such straddles were governed
by Section 1256 of the Code.  The Fund may make one or more elections with
respect to "mixed straddles."  Depending upon which election is made, if any,
the results with respect to the Fund may differ.  Generally, to the extent the
straddle rules apply to positions established by the Fund, losses realized by
the Fund may be deferred to the extent of unrealized gain in any offsetting
positions.  Moreover, as a result of the straddle and the conversion transaction
rules, short-term capital loss on straddle positions may be recharacterized as
long-term capital loss, and long-term capital gain may be characterized as
short-term capital gain or ordinary income.

     If a Fund enters into a "constructive sale" of any appreciated position in
stock, a partnership interest, or certain debt instruments, the Fund must
recognize gain (but not loss) with respect to that position.  For this purpose,
a constructive sale occurs when the Fund enters into one of the following
transactions with respect to the same or substantially identical property: (i) a
short sale; (ii) an offsetting notional principal contract; or (iii) a futures
or forward contract.

     Income and dividends received by the Funds from sources within foreign
countries may be subject to withholding and other taxes imposed by such
countries.

     Capital Gain Distributions.  Distributions which are designated by a Fund
     --------------------------
as capital gain distributions will be taxed to shareholders as long-term term
capital gain (to the extent such dividends do exceed the Fund's actual net
capital gains for the taxable year), regardless of how long a shareholder has
held Fund shares.  Such distributions will be designated as capital gain

                                       29
<PAGE>

distributions in a written notice mailed by the Fund to its shareholders not
later than 60 days after the close of the Fund's taxable year.

     Disposition of Fund Shares.  A disposition of Fund shares pursuant to a
     --------------------------
redemption (including a redemption in-kind) or an exchange will ordinarily
result in a taxable capital gain or loss, depending on the amount received for
the shares (or are deemed to be received in the case of an exchange) and the
cost of the shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred in acquiring the Fund's shares shall not be
taken into account (to the extent such previous sales charges do not exceed the
reduction in sales charges on the new purchase) for the purpose of determining
the amount of gain or loss on the disposition, but will be treated as having
been incurred in the acquisition of such other shares.  Also, any loss realized
on a redemption or exchange of shares of the Fund will be disallowed to the
extent that substantially identical shares are acquired within the 61-day period
beginning 30 days before and ending 30 days after the shares are disposed of.

     If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as a long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as a long-term capital loss to the extent of the designated capital gain
distribution.  In addition, if a shareholder holds Fund shares for six months or
less, any loss on the sale or exchange of those shares will be disallowed to the
extent of the amount of exempt-interest dividends received with respect to the
shares.  The Treasury Department is authorized to issue regulations reducing the
six months holding requirement to a period of not less than the greater of 31
days or the period between regular dividend distributions where a Fund regularly
distributes at least 90% of its net tax-exempt interest, if any.  No such
regulations have been issued as of the date of this SAI.  The loss disallowance
rules described in this paragraph do not apply to losses realized under a
periodic redemption plan.

     Federal Income Tax Rates.  As of the printing of this SAI, the maximum
     ------------------------
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 20%; and the maximum corporate tax rate applicable to
ordinary income and net capital gain is 35% (marginal tax rates may be higher
for some corporations to reduce or eliminate the benefit of lower marginal
income tax rates).  Naturally, the amount of tax payable by an individual or
corporation will be affected by a combination of tax laws covering, for example,
deductions, credits, deferrals, exemptions, sources of income and other matters.

     Backup Withholding.  The Trustees may be required to withhold, subject to
     ------------------
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, if the shareholder fails to certify that the Taxpayer
Identification Number ("TIN") provided is correct and that the shareholder is
not subject to

                                       30
<PAGE>

backup withholding, or if the IRS notifies the Trust that the shareholder's TIN
is incorrect or that the shareholder is subject to backup withholding. Such tax
withheld does not constitute any additional tax imposed on the shareholder, and
may be claimed as a tax payment on the shareholder's federal income tax return.
An investor must provide a valid TIN upon opening or reopening an account.
Failure to furnish a valid TIN to the Trust could also subject the investor to
penalties imposed by the IRS.

     Corporate Shareholders.  Corporate shareholders of the Funds may be
     ----------------------
eligible for the dividends-received deduction on dividends distributed out of a
Fund's net investment income attributable to dividends received from domestic
corporations, which, if received directly by the corporate shareholder, would
qualify for such deduction.  A distribution by a Fund attributable to dividends
of a domestic corporation will only qualify for the dividends-received deduction
if (i) the corporate shareholder generally holds the Fund shares upon which the
distribution is made for at least 46 days during the 90 day period beginning 45
days prior to the date upon which the shareholder becomes entitled to the
distribution; and (ii) the Fund generally holds the shares of the domestic
corporation producing the dividend income for at least 46 days during the 90 day
period beginning 45 days prior to the date upon which the Fund becomes entitled
to such dividend income.

     Foreign Shareholders.  Under the Code, distributions of net investment
     --------------------
income by the Funds to a nonresident alien individual, foreign trust (i.e.,
trust which a U.S. court is able to exercise primary supervision over
administration of that trust and one or more U.S. persons have authority to
control substantial decisions of that trust), foreign estate (i.e., the income
of which is not subject to U.S. tax regardless of source), foreign corporation,
or foreign partnership (a "foreign shareholder") will be subject to U.S.
withholding tax (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend paid by the Fund to a foreign
shareholder is "effectively connected" with a U.S. trade or business (or, if an
income tax treaty applies, is attributable to a U.S. permanent establishment of
the foreign shareholder), in which case the reporting and withholding
requirements applicable to U.S. persons will apply.  Distributions of net long-
term capital gains are generally not subject to tax withholding.

     New Regulations.  On October 6, 1997, the Treasury Department issued new
     ---------------
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1999, subject to certain
transition rules.  Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders that will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax advisors regarding the
New Regulations.

     Tax-Deferred Plan.  The shares of the Funds are available for a variety of
     -----------------
tax-deferred retirement and other plans, including Individual Retirement
Accounts ("IRA"), Simplified Employee Pension Plans ("SEP-IRA"), Savings
Incentive Match Plans for Employees ("SIMPLE plans"), Roth IRAs, and Education
IRAs, which permit investors to defer some of their income from taxes.
Investors should contact their selling agents for details concerning retirement
plans.

     Additional Considerations for the Tax-Free Income Fund.  If at least 50% of
     ------------------------------------------------------
the value of a regulated investment company's total assets at the close of each
quarter of its taxable years consists of obligations the interest on which is
exempt from federal income tax, it will qualify under the Code to pay "exempt-
interest dividends."  The Tax-Free Income Fund intends to so qualify and is
designed to provide investors with a high level of income exempt from federal
income tax.

     The portion of total dividends paid by the Tax-Free Income Fund with
respect to any taxable year that constitutes exempt-interest dividends will be
the same for all shareholders receiving dividends during such year.
Distributions of capital gains or from net investment income not attributable to
interest on the Fund's tax-exempt obligations will not constitute exempt-
interest dividends and will be taxable to its shareholders.  The exemption of
interest income derived from investments in tax-exempt obligations for federal
income tax purposes may not result in a similar exemption under the laws of a
particular state or local taxing authority.

     Not later than 60 days after the close of its taxable year, the Tax-Free
Income Fund will notify its shareholders of the portion of the dividends paid
with respect to such taxable year which constitutes exempt-interest dividends.
The aggregate amount of dividends so designated cannot exceed the excess of the
amount of interest excludable from gross income under Section 103 of the Code
received by the Fund during the taxable year over any amounts disallowed as
deductions under Sections 265 and 171(a)(2) of the Code.  Interest on
indebtedness incurred to purchase or carry shares of the Tax-Exempt Income Fund
will not be deductible to the extent that the Fund's distributions are exempt
from federal income tax.

     In addition, the federal alternative minimum tax ("AMT") rules ensure that
at least a minimum amount of tax is paid by taxpayers who obtain significant
benefit from certain tax deductions and exemptions.  Some of these deductions
and exemptions have been designated "tax preference items" which must be added
back to taxable income for purposes of calculating AMT.  Among the tax
preference items is tax-exempt interest from "private activity bonds" issued
after August 7, 1986.  To the extent that the Tax-Free Income Fund invests in
private activity bonds, its shareholders who pay AMT will be required to report
that portion of Fund dividends attributable to income from the bonds as a tax
preference item in determining their AMT.  Shareholders will be notified of the
tax status of distributions made by the Tax-Free Income Fund.  Persons who may
be "substantial users" (or "related persons" of substantial users) of facilities
financed by private activity bonds should consult their tax advisors before
purchasing shares in the Tax-Free Income Fund.  Furthermore, shareholders will
not be permitted to deduct any of their share of the Tax-Free Income Fund's
expenses in computing their AMT.  With respect to a corporate shareholder of the
Tax-Free Income Fund, exempt-interest dividends paid by the Fund is included in
the corporate shareholder's "adjusted current earnings" as part of its AMT
calculation, and may also affect its federal "environmental tax" liability.  As
of the printing of this SAI, individuals are subject to an AMT at a maximum rate
of 28% and corporations at a maximum rate of 20%.  Shareholders with questions
or concerns about AMT should consult their own tax advisors.

     Shares of the Tax-Free Income Fund would not be suitable for tax-exempt
institutions and may not be suitable for retirement plans qualified under
Section 401 of the Code, H.R. 10 plans and IRAs since such plans and accounts
are generally tax-exempt and, therefore, would not

                                       32
<PAGE>

benefit from the exempt status of dividends from the Fund. Such dividends may
ultimately be taxable to the beneficiaries when distributed to them.

     Other Matters.  Investors should be aware that the investments to be made
     -------------
by the Funds may involve sophisticated tax rules that may result in income or
gain recognition by the Funds without corresponding current cash receipts.
Although the Funds will seek to avoid significant noncash income, such noncash
income could be recognized by the Funds, in which case the Funds may distribute
cash derived from other sources in order to meet the minimum distribution
requirements described above.

     The foregoing discussion and the discussions in the Prospectus applicable
to each shareholder address only some of the Federal tax considerations
generally affecting investments in the Funds.  Each investor is urged to consult
his or her tax advisor regarding specific questions as to federal, state, local
or foreign taxes.

                                 CAPITAL STOCK

     The Funds are four of the funds in the Wells Fargo Funds Trust family of
funds.  The Trust was organized as a Delaware business trust on March 10, 1999.

     Most of the Trust's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors.  Certain of the Trust's funds also are authorized to issue
other classes of shares, which are sold primarily to institutional investors.
Each class of shares in a fund represents an equal, proportionate interest in a
fund with other shares of the same class.  Shareholders of each class bear their
pro rata portion of the fund's operating expenses, except for certain class-
specific expenses (e.g., any state securities registration fees, shareholder
servicing fees or distribution fees that may be paid under Rule 12b-1) that are
allocated to a particular class.  Please contact Shareholder Services at 1-800-
222-8222 if you would like additional information about other funds or classes
of shares offered.

     With respect to matters affecting one class but not another, shareholders
vote as a class; for example, the approval of a Plan.  Subject to the foregoing,
all shares of a Fund have equal voting rights and will be voted in the
aggregate, and not by series, except where voting by a series is required by law
or where the matter involved only affects one series.  For example, a change in
a Fund's fundamental investment policy affects only one series and would be
voted upon only by shareholders of the Fund involved.  Additionally, approval of
an advisory contract, since it affects only one Fund, is a matter to be
determined separately by Series.  Approval by the shareholders of one Series is
effective as to that Series whether or not sufficient votes are received from
the shareholders of the other Series to approve the proposal as to those Series.

     As used in the Prospectus and in this SAI, the term "majority," when
referring to approvals to be obtained from shareholders of a Class of shares of
a Fund, means the vote of the lesser of (i) 67% of the shares of the Class
represented at a meeting if the holders of more than 50% of the outstanding
shares of the Class are present in person or by proxy, or (ii) more than 50% of
the outstanding shares of the Class of the Fund.  The term "majority," when
referring to approvals to be obtained from shareholders of the Fund, means the
vote of the lesser of (i) 67%

                                       33
<PAGE>

of the shares of the Fund represented at a meeting if the holders of more than
50% of the outstanding shares of the Fund are present in person or by proxy, or
(ii) more than 50% of the outstanding shares of the Fund. The term "majority,"
when referring to the approvals to be obtained from shareholders of the Trust as
a whole, means the vote of the lesser of (i) 67% of the Trust's shares
represented at a meeting if the holders of more than 50% of the Trust's
outstanding shares are present in person or by proxy, or (ii) more than 50% of
the Trust's outstanding shares.

     Shareholders are not entitled to any preemptive rights. All shares, when
issued, will be fully paid and non-assessable by the Trust.  The Trust may
dispense with an annual meeting of shareholders in any year in which it is not
required to elect Trustees under the 1940 Act.

     Each share of a class of a Fund represents an equal proportional interest
in the Fund with each other share of the same class and is entitled to such
dividends and distributions out of the income earned on the assets belonging to
the Fund as are declared in the discretion of the Trustees. In the event of the
liquidation or dissolution of the Trust, shareholders of a Fund are entitled to
receive the assets attributable to that Fund that are available for
distribution, and a distribution of any general assets not attributable to a
particular Fund or portfolio that are available for distribution in such manner
and on such basis as the Trustees in their sole discretion may determine.

     Set forth below, as of May 25, 1999, is the name, address and share
ownership of each person known by the Trust to have beneficial or record
ownership of 5% or more of a class of a Fund or 5% or more of the voting
securities as a whole.  The term "N/A" is used where a shareholder holds 5% or
more of a class, but less than 5% of a Fund as a whole.

                                   APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate and municipal bonds, municipal notes, and corporate and municipal
commercial paper.

     Corporate Bonds

     Moody's: The four highest ratings for corporate bonds are "Aaa," "Aa," "A"
and "Baa." Bonds rated "Aaa" are judged to be of the "best quality" and carry
the smallest amount of investment risk. Bonds rated "Aa" are of "high quality by
all standards," but margins of protection or other elements make long-term risks
appear somewhat greater than "Aaa" rated bonds. Bonds rated "A" possess many
favorable investment attributes and are considered to be upper medium grade
obligations. Bonds rated "Baa" are considered to be medium grade obligations;
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. Moody's
also applies numerical modifiers in its rating system: 1, 2 and 3 in each rating
category from "Aa" through "Baa" in its rating system. The modifier 1 indicates
that the security ranks in the higher end of its category; the modifier 2
indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks
in the lower end.

     S&P: The four highest ratings for corporate and municipal bonds are "AAA,"
"AA," "A" and "BBB." Bonds rated "AAA" have the "highest rating" assigned by S&P
and have "an extremely strong capacity" to pay interest and repay principal.
Bonds rated "AA" have a "very strong capacity" to pay interest and repay
principal and "differ from the highest rated obligations only in small degree."
Bonds rated "A" have a "strong capacity" to pay interest and repay principal,
but are "somewhat more susceptible" to adverse effects of changes in economic
conditions or other circumstances than bonds in higher rated categories. Bonds
rated "BBB" are regarded as having "adequate protection parameters" to pay
interest and repay principal, but changes in economic conditions or other
circumstances are more likely to lead to a "weakened capacity" to make such
repayments. The ratings from "AA" to "BBB" may be modified by the addition of a
plus or minus sign to show relative standing within the category.

     Commercial Paper

     Moody's: The highest rating for commercial paper is "P-1" (Prime-1).
Issuers rated "P-1" have a "superior ability for repayment of senior short-term
debt obligations." Issuers rated "P-2" (Prime-2) "have a strong capacity for
repayment of senior short-term debt obligations," but earnings trends, while
sound, will be subject to more variation.

                                      A-1
<PAGE>

     S&P: The "A-1" rating for commercial paper is rated "in the highest
category" by S&P and "the obligor's capacity to meet its financial commitment on
the obligation is strong." The "A-1+" rating indicates that said capacity is
"extremely strong." The A-2 rating indicates that said capacity is
"satisfactory," but that corporate and municipal commercial paper rated "A-2" is
"more susceptible" to the adverse effects of changes in economic conditions or
other circumstances than commercial paper rated in higher rating categories.

SUMMARY OF IMPORTANT RISKS

 This section summarizes important risks that are common to all of the Funds
 described in this Prospectus, and important risks that relate specifically to
 particular Funds.  Both are important to your investment choice.  Additional
 information about these and other risks is included in the individual Fund
 descriptions later in this Prospectus, under General Investment Risks beginning
 on page __ and the Fund's Statement of Additional Information.  An investment
 in a Fund is not a deposit of Wells Fargo Bank and is not insured or guaranteed
 by the Federal Deposit Insurance Corporation or any other government agency.

 Common Risks for the Funds

 The Funds may invest in debt instruments, such as notes and bonds, which are
 subject to credit risk and interest rate risk.  Credit risk is the possibility
 that an issuer of an instrument will be unable to make interest payments or
 repay principal.  Changes in the financial strength of an issuer or changes in
 the credit rating of a security may affect its value.  Interest rate risk is
 the risk that interest rates may increase, which will reduce the resale value
 of instruments in a Fund's portfolio, including U.S. Government obligations.
 Debt securities with longer maturities are generally more sensitive to interest
 rate changes than those with shorter maturities.  Changes in market interest
 rates do not affect the rate payable on debt instruments held in a Fund, unless
 the instrument has adjustable or variable rate features, which can reduce
 interest rate risk.  Changes in market interest rates may also extend or
 shorten the duration of certain types of instruments, such as asset-backed
 securities, thereby affecting their value and the return on your investment.

 The Funds invest in municipal obligations that rely on the creditworthiness or
 revenue production of their issuers.  Municipal obligations may be difficult to
 obtain because of limited supply, which may increase the cost of such
 securities and effectively reduce the portfolio's yield.  Typically, less
 information is available about a municipal issuer than is available for other
 types of securities issuers.

 Although we strive to invest in municipal obligations and other securities
 whose interest is exempt from federal income taxes, some distribution income
 earned may be subject to the federal alternative minimum tax ("AMT").

 Tax-Free Funds take advantage of tax laws that allow the income from certain
 investments to be exempted from federal and, in some cases, state personal
 income tax.  Capital gains, whether declared by a Fund or realized by the
 shareholder through the selling of Fund shares, are generally taxable.

 Each Fund is considered non-diversified according to the Investment Company Act
 of 1940, as amended ("the 1940 Act").  The majority of the issuers of the
 securities in the Fund's portfolio are located within one state.  Non-
 diversified, geographically concentrated funds are riskier than similar funds
 that are diversified or spread their investments over several geographic areas.
 Default by a single security in the portfolio may have a greater negative
 affect than a similar default in a diversified portfolio.

FUND-SPECIFIC RISKS

 Minnesota Tax-Free Fund
 The Fund may invest up to 25% of its total assets in non-investment grade
 municipal obligations, commonly known as "high yield/high risk securities" or
 "junk bonds," which are considered a more speculative investment than
 investment grade municipal obligations.

 Performance History
 The Funds in this Prospectus will commence operations in September 1999.  No
 performance information is given for the Funds because they will have been in
 operation for less than one year.

Arizona Tax-Free Fund

Investment Objective
The Arizona Tax-Free Fund seeks to provide investors with current income exempt
from federal income tax and Arizona personal income tax.

Investment Policies
We actively manage a portfolio of municipal obligations and we buy municipal
obligations of any maturity length.  The portfolio's weighted average maturity
will vary depending on market conditions, economic conditions including interest
rates, the differences in yields between obligations of different maturity
lengths and other factors.  Generally speaking, we will attempt to capture
greater total return by increasing maturity when we expect interest rates to
decline, and attempt to preserve capital by shortening maturity when interest
rates are expected to increase.

Permitted Investments
Under normal market conditions, we invest:

 .  at least 80% of our assets in municipal obligations that pay interest exempt
   from federal income tax;
 .  at least 65% of our assets in municipal obligations that pay interest exempt
   from Arizona personal income tax; and
 .  in municipal obligations rated in the four highest credit categories by
   nationally recognized rating organizations ("NRRO").

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interests of shareholders
to do so. During such periods, the Fund may not achieve its investment
objective.

Important Risk Factors
The Fund is considered non-diversified according to the Investment Company Act
of 1940 (the "1940 Act").  The majority of the issuers of the securities in the
Fund's portfolio are located within Arizona.  Non-diversified, geographically
concentrated funds are riskier than similar funds that are diversified or spread
their investments over several geographic areas.  Default by a single security
in the portfolio may have a greater negative affect than a similar default in a
diversified portfolio.

You should consider both the General Investment Risks listed on page __ and the
specific risks listed above.  They are equally important to your investment
choice.

California Tax-Free Fund

Investment Objective
The California Tax-Free Fund seeks to provide investors with a high level of
current income exempt from federal income tax and California personal income
tax, while preserving capital, by investing in medium- to long-term investment-
grade municipal securities.

Investment Policies
We actively manage a portfolio of municipal obligations.  We buy municipal
obligations of any maturity length, but we invest substantially all of our
assets in securities with remaining maturities of 2 to 10 years (medium term) or
10 years or longer (long term).  We have some flexibility in setting the
portfolio's dollar-weighted average maturity.  Generally speaking, we will
attempt to capture greater total return by increasing dollar-weighted average
maturity when we expect interest rates to decline, and attempt to preserve
capital by shortening maturity when interest rates are expected to increase.

Permitted Investments
Under normal market conditions, we invest:

 .  at least 80% of our assets in municipal obligations that pay interest exempt
   from federal income tax;
 .  at least 65% of our assets in municipal obligations that pay interest exempt
   from California personal income tax; and
 .  in municipal obligations rated in the four highest credit categories by
   NRROs.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interests of shareholders
to do so. During such periods, the Fund may not achieve its investment
objective.

Important Risk Factors
The Fund is considered non-diversified according to the 1940 Act.  The majority
of the issuers of the securities in the portfolio are located within California.
Non-diversified, geographically concentrated funds are riskier than similar
funds that are diversified or spread their investments over several geographic
areas.  Default by a single security in the portfolio may have a greater
negative affect than a similar default in a diversified portfolio.

Municipal obligations rely on the creditworthiness or revenue production of
their issuers.  Municipal obligations may be difficult to obtain because of
limited supply, which may increase the cost of such securities and effectively
reduce the portfolio's yield.  Typically, less information is available about a
municipal issuer than is available for other types of securities issuers.

You should consider both the General Investment Risks listed on page __ and the
specific risks listed above.  They are equally important to your investment
decision.

California Limited Term Tax-Free Fund

Investment Objective
The California Limited Term Tax-Free Fund seeks to provide investors with a high
level of current income exempt from federal income tax and California personal
income tax, while preserving capital.

Investment Policies
We actively manage a portfolio of municipal obligations.  We buy municipal
obligations of any maturity length, but we primarily buy securities with
remaining maturities of less than 2 years (short-term) or 2 to 10 years (medium-
term).  We have some flexibility in setting the portfolio's dollar-weighted
average maturity.  Generally speaking, we will attempt to capture greater total
return by increasing dollar-weighted average maturity when we expect interest
rates to decline, and attempt to preserve capital by shortening maturity when
interest rates are expected to increase.  Under normal market conditions, the
average expected duration of the Fund's portfolio securities will be from 1 to 5
years.

Permitted Investments
Under normal market conditions, we invest:

 .  at least 80% of our assets in municipal obligations that pay interest exempt
   from federal income tax;
 .  at least 65% of our assets in municipal obligations that pay interest exempt
   from California personal income tax; and
 .  in municipal obligations rated in the four highest credit categories by
   NRROs.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interests of shareholders
to do so. During such periods, the Fund may not achieve its investment

Colorado Tax-Free Fund

Investment Objective
The Colorado Tax-Free Fund seeks to provide investors with a high level of
current income exempt from both federal and Colorado state income taxes
consistent with the preservation of capital.  The Fund offers shares only to
residents of Colorado.

Investment Policies
The Fund normally invests substantially all of its assets in investment grade
municipal obligations issued by the state of Colorado and its subdivisions,
authorities, instrumentalities, and corporations, and by the territories and
possessions of the United States.

The Advisor expects that the Fund's average portfolio maturity normally will be
greater than 10 years.  The Fund's average portfolio maturity may reach or
exceed 20 years in the future.  Depending on market conditions, the Fund's
dollar-weighted average maturity could be higher or lower.  The Fund emphasizes
investments in municipal obligations paying interest income rather than
maintaining the Fund's stability of net asset value.  The Fund also attempts to
limit net asset value fluctuations.

Permitted Investments
As a fundamental policy, the Fund will invest at least 80% of its assets in
municipal obligations paying interest exempt from both federal and Colorado
state income taxes.  The Fund invests in securities of a comparatively small
number of issuers.  The Fund will not invest more than 25% of its total assets
in securities of related issuers or in securities of any one issuer, except the
U.S. Government.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interest of shareholders to
do so. During such periods, the Fund may not achieve its investment objective.

Important Risk Factors
All investments in a Fund are subject to risk and may decline in value.  The
amount and types of risk vary depending on the Fund's investment objective, the
Advisor's strategy, the markets in which the Fund invests, the investments that
the Fund makes and prevailing economic conditions over the period of your
investment.

The investment income you receive from a Fund will vary with changes in interest
rates.  In addition, the value of the Fund's investments generally will fall
when interest rates rise and rise when interest rates fall.  When interest rates
fall, there is a risk that issuers will prepay fixed rate securities, forcing
the Fund to invest in securities with lower interest rates than the prepaid
securities.

The yields of Colorado municipal obligations depend on, among other things,
conditions in the Colorado municipal obligations market and fixed-income markets
generally, the size of a particular offering, the maturity of the securities,
and the rating of the issue.  In some cases, Colorado issues may have yields
that are slightly less than the yields of municipal obligations of issuers
located in other states because of the favorable Colorado state tax exemption on
Colorado issues.

The Fund is considered non-diversified according to the 1940 Act.  The majority
of the issuers of the securities in the portfolio are located within Colorado.
Non-diversified, geographically concentrated funds are riskier than similar
funds that are diversified or spread their investments over several geographical
areas.  Default by a single security in the portfolio may have a greater
negative affect than a similar default in a diversified portfolio.

Municipal obligations rely on the creditworthiness or revenue production of
their issuers.  Municipal obligations may be difficult to obtain because of
limited supply, which may increase the cost of such securities and effectively
reduce the portfolio's yield.  Typically, less information is available about a
municipal issuer than is available for other types of securities issuers.

Minnesota Tax-Free Fund

Investment Objective
The Minnesota Tax-Free Fund seeks to provide investors with a high level of
current income exempt from both federal and Minnesota state income taxes without
assuming undue risk.

Investment Policies
The Fund normally invests substantially all (and always at least 75% of) its
assets in investment grade municipal obligations issued by the state of
Minnesota and its subdivisions, authorities, instrumentalities, and
corporations, and by the territories and possessions of the United States.

There are no restrictions on Minnesota Tax-Free Fund's average portfolio
maturity.  The Advisor expects that the Fund's dollar-weighted average maturity
normally will be greater than 10 years.  The Fund's average portfolio maturity
may reach or exceed 20 years in the future.  Depending on market conditions, the
Fund's average dollar-weighted average maturity could be higher or lower.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments either to maintain liquidity of for short-term
defensive purposes when we believe it is in the best interest of shareholders to
do so. During such periods, the Fund may not achieve its investment objective.

The Fund emphasizes investments in municipal obligations paying interest income
rather than maintaining the Fund's stability of net asset value.

Permitted Investments
As a fundamental policy, the Fund will invest at least 80% of its total assets
in securities paying interest exempt from both federal and Minnesota state
income taxes.  The Fund may invest in securities of a comparatively small number
of issuers.  The Fund will not invest more than 25% of its total assets in
securities of related issuers or in securities of any one issuer, except the
U.S. Government.

The Fund may invest up to 25% of its total assets in non-investment grade
municipal obligations.

Important Risk Factors
All investments in a Fund are subject to risk and may decline in value.  The
amount and types of risk vary depending on the Fund's investment objective, the
Advisor's strategy, the markets in which the Fund invests, the investments that
the Fund makes and prevailing economic conditions over the period of your
investment.

The investment income you receive from a Fund will vary with changes in interest
rates.  In addition, the value of the Fund's investments generally will fall
when interest rates rise and rise when interest rates fall.  When interest rates
fall, there is a risk that issuers will prepay fixed rate securities, forcing
the Fund to invest in securities with lower interest rates than the prepaid
securities.

The yields of Minnesota municipal obligations depend on, among other things,
conditions in the Minnesota municipal obligations market and fixed-income
markets generally, the maturity of the securities, the rating of the issue, and
the size of a particular offering.  In some cases, Minnesota issues may have
yields that are slightly less than the yields of municipal obligations of
issuers located in other states because of the favorable Minnesota state tax
exemption on Minnesota issues.

The Fund is considered non-diversified according to the 1940 Act.  The majority
of the issuers of the securities in the portfolio are located within Minnesota.
Non-diversified, geographically concentrated funds are riskier than similar
funds that are diversified or spread their investments over several geographical
areas.  Default by a single security in the portfolio may have a greater
negative affect than a similar default in a diversified portfolio.

The Fund may invest up to 25% of its total assets in non-investment grade
municipal obligations, commonly known as "high yield/high risk securities" or
"junk bonds," which are considered a more speculative investment than investment
grade municipal obligations with respect to the issuer's capacity to

                                       16
<PAGE>

pay interest and repay principal. Below investment grade securities also tend to
be more sensitive to economic conditions than higher-rated securities. These
securities generally involve more credit risk.

Municipal obligations rely on the creditworthiness or revenue production of
their issuers.  Municipal obligations may be difficult to obtain because of
limited supply, which may increase the cost of such securities and effectively
reduce the portfolio's yield.  Typically, less information is available about a
municipal issuer than is available for other types of securities issuers.

specific risks listed above.  They are equally important to your investment
choice.

Oregon Tax-Free Fund

Investment Objective
The Oregon Tax-Free Fund seeks to provide investors with a high level of current
income exempt from federal income tax and Oregon personal income tax.

Investment Policies
We actively manage a portfolio of municipal obligations and we buy municipal
obligations of any maturity length.  The portfolio's weighted average maturity
will vary depending on market conditions, economic conditions including interest
rates, the differences in yields between obligations of different maturity
lengths and other factors.  There is no required range for the portfolio's
dollar weighted average maturity.  Generally speaking, we will attempt to
capture greater total return by increasing maturity when we expect interest
rates to decline, and attempt to preserve capital by shortening maturity when
interest rates are expected to increase.

Permitted Investments
Under normal market conditions, we invest:

 .  at least 80% of our assets in municipal obligations that pay interest exempt
   from federal income tax;

 .  at least 65% of our assets in municipal obligations that pay interest exempt

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds Trust Funds.  Certain common risks are
identified in the Summary of Important Risks on page ___.  Other risks of mutual
fund investing include the following:

 .  Unlike bank deposits, such as CDs or savings accounts, mutual funds are not
   insured by the FDIC.

 .  We cannot guarantee that we will meet our investment objectives.

 .  We do not guarantee the performance of a Fund, nor can we assure you that the
   market value of your investment will not decline. We will not "make good" any
   investment loss you may suffer, nor can anyone we contract with to provide
   certain services, such as selling agents or investment advisors, offer or
   promise to make good any such losses.

 .  Share prices -- and therefore the value of your investment -- will increase
   and decrease with changes in the value of the underlying securities and other
   investments.  This is referred to as price volatility.

 .  Investing in any mutual fund, including those deemed conservative, involves
   risk, including the possible loss of any money you invest.

 .  An investment in a single Fund, by itself, does not constitute a complete
   investment plan.

 .  Each Fund may continue to hold debt-instruments that cease to be rated by a
   NRROs or whose ratings fall below the levels generally permitted for such
   Fund, provided Wells Fargo deems the instrument to be of comparable quality
   to rated or higher-rated instruments. Unrated or downgraded instruments may
   be more susceptible to credit and interest rate risks than investment grade
   bonds.

 .  The Funds may invest a portion of their assets in U.S. Government obligations
   such as securities issued or guaranteed by the Government National Mortgage
   Association ("GNMAs"), the Federal National Mortgage Association ("FNMAs")
   and the Federal Home Loan Mortgage Corporation ("FHLMCs"). Each are mortgage-
   backed securities representing partial ownership of a pool of residential
   mortgage loans. A "pool" or group of such mortgages is assembled and, after
   being approved by the issuing or guaranteeing entity, is offered to investors
   through securities dealers. Mortgage-backed securities are subject to
   prepayment and extension risk, which can alter the maturity of the securities
   and also reduce the rate of return on the portfolio. Collateralized mortgage
   obligations ("CMOs") typically represent principal-only and interest-only
   portions of such securities and are subject to increased interest-rate and
   credit risk. It is important to recognize that the U.S. Government does not
   guarantee the market value or current yield of those obligations. Not all
   U.S. Government obligations are backed by the full faith and credit of the
   U.S. Treasury, and the U.S. Government's guarantee does not extend to the
   Funds themselves.

 .  The Funds may also use certain derivative instruments, such as options or
   futures contracts. The term "derivatives" covers a wide number of
   investments, but in general it refers to any financial instrument whose value
   is derived, at least in part, from the price of another security or a
   specified index, asset or rate. Some derivatives may be more sensitive to
   interest rate changes or market moves, and some may be susceptible to changes
   in yields or values due to their structure or contract terms.

 .  The Funds may temporarily hold assets in cash or in money market instruments,
   including U.S. Government obligations, shares of other mutual funds and
   repurchase agreements, or make other short-term investments, either to
   maintain liquidity or for short-term defensive purposes when we believe it is
   in the best interests of shareholders to do so. To the extent a Fund's assets
   are so invested, they may cause a Fund not to achieve its investment
   objective. This practice is expected to have limited, if any, effect on the
   Fund's pursuit of their objectives over the long term.

Investment practices and risk levels are carefully monitored.  Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

 General Investment Risks (Cont'd)

What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Fund and a table showing some of the
additional investment practices that each Fund may use and the risks associated
with them.  Additional information about these practices is available in the
Statement of Additional Information.

Counter-Party Risk--The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule.  If an issuer does default,
the affected security could lose all of its value, or be renegotiated at a lower
interest rate or principal amount.  Affected securities might also lose
liquidity.  Credit risk also includes the risk that a party in a transaction may
not be able to complete the transaction as agreed.

Experience Risk--The risk presented by a new or innovative security.  The risk
is that insufficient experience exists to forecast how the security's value
might be affected by various economic conditions.

Extension Risk--The risk that an interest rates rise, prepayments slow, thereby
lengthening the duration and potentially reducing the value of certain asset-
backed securities.

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security.  Generally, when interest rates increase, the value of
a debt security decreases.  The effect is usually more pronounced for securities
with longer dates to maturity.

Leverage Risk--The risk that a practice may increase a Fund's exposure to market
risk, interest rate risk or other risks by, in effect, increasing assets
available for investment.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of a stock, bond or other security will be
reduced by market activity.  This is a basic risk associated with all
securities.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.  Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Year 2000 Risk--The Funds' principal service providers have advised the Funds
that they are working on the necessary changes to their computer systems to
avoid any system failure based on an inability to distinguish the year 2000 from
the year 1900, and that they expect their systems to be adapted in time.  There
can, of course, be no assurance of success.  In addition, the companies or
entities in which the Funds invest also could be adversely impacted by the Year
2000 issue, especially foreign entities, which may be less prepared for Year
2000.  The extent of such impact cannot be predicted.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund.  You should also
see the Statement of Additional Information for additional information about the
investment practices and risks particular to each Fund.

Investment Practice/Risk

The following table lists some of the additional investment practices of the
Funds, including some not disclosed in the Investment Objective and Investment
Policies sections of the Prospectus.  The risks indicated after the description
of the practice are NOT the only potential risks associated with that practice,
but are among the more prominent.  Market risk is assumed for each.  See the
Investment Objective and Investment Policies for each Fund or the Statement of
Additional Information for more information on these practices.

Investment practices and risk levels are carefully monitored.  We attempt to
ensure that the risk exposure for each Fund remains within the parameters of its
objective.

Remember, each Fund is designed to meet different investment needs and
objectives.

Organization and Management of the Funds

A number of different entities provide services to the Funds.  This section
shows how the Funds are organized, the entities that perform different services,
and how they are compensated.  Further information is available in the Statement
of Additional Information for the Funds.

About Wells Fargo Funds Trust

Wells Fargo Funds Trust ("Funds Trust") was organized as a Delaware business
trust on March 10, 1999.  The Board of Trustees of Funds Trust supervises each
Fund's activities, monitors its contractual arrangements with various service
providers and decides upon matters of general policy.  Each Fund is one of over
60 Funds of Funds Trust.

Funds Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds.  The holding company of Wells Fargo Bank, the investment advisor to
the Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998.  Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one or more Stagecoach
and/or Norwest Advantage Funds.  One of these predecessor funds is expected to
be the "accounting survivor," which means that its performance and financial
statement history will be assumed by the Funds Trust Fund.  The succession
transactions are conditioned on shareholder approval by the shareholders of the
various Stagecoach and Norwest Advantage Funds.  The Table on page __ identifies
the expected accounting survivors.

The Board of Trustees of Funds Trust supervises the Funds' activities and
approves the selection of various companies hired to manage the Funds'
operation.  The major service providers are described in the diagram below.
Except for the advisors, which require shareholder vote to change, if the Board
believes that it is in the best interests of the shareholders, it may make a
change in one of these companies.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund class paid on an annual basis for the
services described.

The Investment Advisor
Wells Fargo Bank provides portfolio management and fundamental security analysis
services as the advisor for each of the Funds.  Wells Fargo Bank, founded in
1852, is the oldest bank in the western United States and is one of the largest
banks in the United States.  Wells Fargo Bank is a wholly owned subsidiary of
Wells Fargo & Company, a national bank holding company.  As of December 31,
1998, Wells Fargo Bank and its affiliates managed over $202 billion in assets.
For providing these services, Wells Fargo Bank is entitled to receive the
following fees:

The Investment Sub-Advisor
Wells Capital Management Incorporated ("WCM"), a wholly owned subsidiary of
Wells Fargo Bank, N.A., is the sub-advisor for each of the Funds.  As of
December 31, 1998, WCM provided investment advice for assets in excess of $39
billion.  For providing sub-advisory services to the Funds, WCM is entitled to
receive from Wells Fargo Bank .15% of each Fund's assets up to the first $400
million, .125% of the next $400 million in assets, and .10% of all assets over
$800 million.  WCM is entitled to receive from Wells Fargo Bank a minimum annual
sub-advisory fee of $120,000.  This minimum annual fee payable to WCM does not
affect the advisory fee paid by the Funds to Wells Fargo Bank.

The Administrator
Wells Fargo Bank provides the Funds with administration services, including
general supervision of each Fund's operation, coordination of the other services
provided to each Fund, compilation of information for reports to the SEC and the
state securities commissions, preparation of proxy statements and shareholder
reports, and general supervision of data compilation in connection with
preparing periodic reports to the Trust's Trustees and officers.  Wells Fargo
Bank also furnishes office space and certain facilities to conduct each Fund's
business, and compensates the Trust's Trustees.  For providing these services,
Wells Fargo Bank is entitled to receive a fee of up to .15% of the average
annual net assets of each Fund.

Shareholder Servicing Plan
We have a shareholder servicing plan for each Fund.  We have agreements with
various shareholder servicing agents to process purchase and redemption
requests, to service shareholder accounts, and to provide other related
services.  For providing these services, the shareholder servicing agents will
receive .25% in fees.

A Choice of Share Classes
After choosing a Fund, your next most important choice is which share class to
buy.  The following classes of shares are available through this Prospectus:

 .    Class A Shares - with a front-end sales charge, volume reductions and lower
     on-going expenses than Class B and Class C shares.

 .    Class B Shares - with a contingent deferred sales charge ("CDSC") payable
     upon redemption that diminishes over time, and higher on-going expenses
     than Class A shares.

 .    Class C Shares - with a 1.00% CDSC on redemptions made within one year of
     purchase, and higher on-going expenses than Class A shares.

The choice between share classes is largely a matter of preference.  You should
consider, among other things, the different fees and sales loads assessed on
each share class and the length of time you anticipate holding your investment.
If you prefer to pay sales charges up front, wish to avoid higher on-going
expenses, or, more importantly, you think you may qualify for volume discounts
based on the amount of your investment, then Class A shares may be the choice
for you.

You may prefer to see "every dollar working" from the moment you invest.  If so,
then consider Class B or Class C shares.  Please note that Class B shares
convert to Class A shares after seven years to avoid the higher on-going
expenses assessed against Class B shares.

Class C shares are available for the California Tax-Free Fund only.  They are
similar to Class B shares, with some important differences.  Unlike Class B
shares, Class C shares do not convert to Class A shares.  The higher on-going
expenses will be assessed as long as you hold the shares.  The choice between
Class B and Class C shares may depend on how long you intend to hold Fund shares
before redeeming them.

Please see the expenses listed for each Fund and the following sales charge
schedules before making your decision.  You should also review the "Reduced
Sales Charges" section of the Prospectus.  You may wish to discuss this choice
with your financial consultant.

Class A Share Sales Charge Schedule
If you choose to buy Class A shares, you will pay the Public Offering Price
(POP) which is the Net Asset Value (NAV) plus the applicable sales charge.
Since sales charges are reduced for Class A share purchases above certain dollar
amounts, known as "breakpoint levels," the POP is lower for these purchases.

Class B Share CDSC Schedule
If you choose Class B shares, you buy them at NAV and agree that if you redeem
your shares within six years of the purchase date, you will pay a CDSC based on
how long you have held your shares.  Certain exceptions apply (see "Class B and
Class C Share CDSC Reductions" and "Waivers for Certain Parties").  The CDSC
schedule is as follows:

- --------------------------------------------------------------------------------------------------
</TABLE>

The CDSC percentage you pay is based on the lower of the NAV of the shares
on the date of the original purchase, or the NAV of the shares on the date of
redemption.

We always process partial redemptions so that the least expensive shares are
redeemed first in order to reduce your sales charges.  After shares are held for
six years, the CDSC expires.  After shares are held for seven years, the Class B
shares are converted to Class A shares to reduce your future on-going expenses.

Class B shares received in the reorganization of the Stagecoach Funds are
subject to the above CDSC schedule based on the purchase date(s) of the
Stagecoach shares, and such shares convert to Class A shares automatically after
six years.

Class B shares received in the reorganization of the Stagecoach Funds in
exchange for Stagecoach Fund shares that were purchased prior to March 3, 1997
are subject to a CDSC if they are redeemed within four years of the original
purchase.  The CDSC Schedule for these shares is below:

Class C Share CDSC Schedule
If you choose Class C shares, you buy them at NAV and agree that if you redeem
your shares within one year of the purchase date, you will pay a CDSC of 1.00%.

The CDSC percentage you pay is based on the lower of the NAV on the date of the
original purchase, or the NAV on the date of redemption.  The Distributor pays
sales commissions of up to 1.00% of the purchase price of Class C shares to
selling agents at the time of the sale, and up to 1.00% annually thereafter.

We always process partial redemptions so that the least expensive shares are
redeemed first in order to reduce your sales charges.  Class C shares do not
convert to Class A shares, and therefore continue to pay the higher on-going
expenses.

                                       28
<PAGE>

Reduced Sales Charges
Generally, we offer more sales charge reductions for Class A shares than for
Class B and Class C shares, particularly if you intend to invest greater
amounts.  You should consider whether you are eligible for any of the potential
reductions when you are deciding which share class to buy.

Class A Share Reductions:  [Please confirm]

 .  You pay no sales charges on Fund shares you buy with reinvested
   distributions.

 .  You pay a lower sales charge if you are investing an amount over a breakpoint
   level.  See the "Class A Share Sales Charge Schedule" above.

 .  By signing a Letter of Intent (LOI), you pay a lower sales charge now in
   exchange for promising to invest an amount over a specified breakpoint within
   the next 13 months. We will hold in escrow shares equal to approximately 5%
   of the amount you intend to buy. If you do not invest the amount specified in
   the LOI before the expiration date, we will redeem enough escrowed shares to
   pay the difference between the reduced sales load you paid and the sales load
   you should have paid. Otherwise, we will release the escrowed shares when you
   have invested the agreed amount.

 .  Rights of Accumulation (ROA) allow you to combine the amount you invest with
   the total NAV of shares you own in other Wells Fargo front-end load Funds in
   order to reach breakpoint levels for a reduced load. We give you a discount
   on the entire amount of the investment that puts you over the breakpoint
   level.

 .  If you are reinvesting the proceeds of a Wells Fargo Fund redemption for
   shares on which you have already paid a front-end sales charge, you have
   [120] days to reinvest the proceeds of that redemption with no sales charge
   into a Fund that charges the same or a lower front-end sales charge. If you
   use such a redemption to purchase shares of a Fund with a higher front-end
   sales charge, you will have to pay the difference between the lower and
   higher charge.

 .  You may reinvest into a Wells Fargo Fund with no sales charge a required
   distribution from a pension, retirement, benefits, or similar plan for which
   Wells Fargo Bank acts as trustee provided the distribution occurred within
   the 30 days prior to your reinvestment.

If you believe you are eligible for any of these reductions, it is up to you to
ask the selling agent or the shareholder servicing agent for the reduction and
to provide appropriate proof of eligibility.

You, or your fiduciary or trustee, may also tell us to extend volume discounts,
including the reductions offered for rights of accumulation and letters of
intent, to include purchases made by:

 .  a family unit, consisting of a husband and wife and children under the age of
   twenty-one or single trust estate;

 .  a trustee or fiduciary purchasing for a single fiduciary relationship; or

 .  the members of a "qualified group" which consists of a "company" (as defined
   in the 1940 Act), and related parties of such a "Company," which has been in
   existence for at least six months and which has a primary purpose other than
   acquiring Fund shares at a discount.

- --------------------------------------------------------------------------------
How a Letter of Intent Can Save You Money!
If you plan to invest, for example, $100,000 in a Fund in installments over the
next year, by signing a letter of intent you would pay only 3.50% sales load on
the entire purchase. Otherwise, you might pay 4.50% on the first $50,000, then
4.00% on the next $49,999!
- --------------------------------------------------------------------------------

Class B and Class C Share Reductions:

 .  You pay no CDSC on Funds shares you purchase with reinvested distributions.

 .  [We waive the CDSC for all redemptions made because of scheduled or mandatory
   distributions for certain retirement plans.] (See your retirement plan
   disclosure for details.)

                                       29
<PAGE>

Reduced Sales Charges (Cont'd)

 .  We waive the CDSC for redemptions made in the event of the shareholder's
   death or for a disability suffered after purchasing shares. ("Disability" is
   defined by the Internal Revenue Code of 1986).

 .  We waive the CDSC for redemptions made at the direction of Wells Fargo in
   order to, for example, complete a merger or close an account whose value has
   fallen below the minimum balance.

 .  We waive Class C share CDSC for certain types of accounts.

For Class B shares purchased [outside of an IRA] or other qualified plan after
May 18, 1999 for former Norwest Advantage Fund shareholders, after July 17, 1999
for former Stagecoach Funds shareholders, and after September 17, 1999 for all
other shareholders, no CDSC is imposed on withdrawals that occur under the
following circumstances:

 .  Withdrawals are made by participating in the Systematic Withdrawal Plan;

 .  Withdrawals may not exceed 10% of your fund assets annually based on your
   anniversary date in the Systematic Withdrawal Plan; and

 .  you must participate in the dividend and capital gain reinvestment program.

Waiver for Certain Parties
If you are eligible for certain waivers, we will sell you Class A shares so you
can avoid higher on-going expenses.  The following people can buy Class A shares
at NAV:
 .  Current and retired employees, directors/trustees and officers of:

   .  Wells Fargo Funds Trust and its affiliates;

   .  Wells Fargo Bank, Norwest Bank and their affiliates;

   .  Stephens and its affiliates; and

   .  Broker-Dealers who act as selling agents.

 .  [The spouses of any of the above, as well as the grandparents, parents,
   siblings, children, grandchildren, aunts, uncles, nieces, nephews,
   fathers-in-law, mothers-in-law, brothers-in-law and sisters-in-law of either
   the spouse or the current or retired employee, director of officer.]

You may also buy Class A Fund shares at NAV if they are to be included in
certain retirement, benefits, pension or investment "wrap accounts" with whom
Wells Fargo Funds has reached an agreement, or through an omnibus account
maintained with a Fund by a broker/dealer.

We reserve the right to enter into agreements that reduce or eliminate sales
charges for groups or classes of shareholders, or for Fund shares included in
other investment plans such as "wrap accounts."  If you own Fund shares as part
of another account or package such as an IRA or a sweep account, you must read
the directions for that account.  These directions may supersede the terms and
conditions discussed here.

Distribution Plan
We have adopted Distribution Plans pursuant to Rule 12b-1 of the 1940 Act for
the Class B and Class C shares of the Funds.  The plans authorize the payment of
all or part of the cost of preparing and distributing prospectuses and
distribution-related services including ongoing compensation to selling agents.
The plan also provides that, if and to the extent any shareholder servicing
payments are recharacterized as payments for distribution-related services, they
are approved and payable under the distribution plan.  The fees paid under these
plans shall be as follows:

Reduced Sales Charges (Cont'd)

These fees are paid out of the Funds' assets on an on-going basis.  Over time,
these fees will increase the cost of your investment and may cost you more than
paying other types of sales charges.

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:
 .  As with all mutual fund investments, the price you pay to purchase shares or
   the price you receive when you redeem shares is not determined until after a
   request has been received in proper form.

 .  We determine the Net Asset Value ("NAV") of each class of the Funds' shares
   each business day as of the close of regular trading on the NYSE. We
   determine the NAV by subtracting the Fund class's liabilities from its total
   assets, and then dividing the result by the total number of outstanding
   shares of that class. Each Fund's assets are generally valued at current
   market prices. See the Statement of Additional Information for further
   disclosure.

 .  We process requests to buy or sell shares of the Funds each business day as
   of the close of regular trading on the New York Stock Exchange ("NYSE"),
   which is usually 1:00 p.m. (Pacific time)/3:00 p.m. (Central time). If the
   markets close early, the Funds may close early and may value their shares at
   earlier times under these circumstances. Any request we receive in proper
   form before these times is processed the same day. Requests we receive after
   the cutoff times are processed the next business day.

 .  The Funds are open for business on each day the NYSE is open for business.
   NYSE holidays include New Year's Day, Martin Luther King, Jr. Day,
   President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
   Thanksgiving Day and Christmas Day. When any holiday falls on a weekend, the
   NYSE typically is closed on the weekday immediately before or after such
   holiday.

You can buy Fund shares:
 .  By opening an account directly with the Fund (simply complete and return a
   Wells Fargo Funds Trust application with proper payment);

 .  Through a brokerage account with an approved selling agent; or

 .  Through certain retirement, benefits and pension plans, or through certain
   packaged investment products (please see the providers of the plan for
   instructions).

Minimum Investments:
 .  $1,000 per Fund minimum initial investment;1 or
 .  $100 per Fund if you use the Systematic Purchase Program; and
 .  $100 per Fund for all investments after your first.

/1/  Purchases of Class B shares in amounts of $250,000 or more require the
     prior approval of your selling agent.

     We may waive the minimum for Funds you purchase through certain retirement,
     benefit and pension plans, through certain packaged investment products, or
     for certain classes of shareholders as permitted by the SEC. Check the
     specific disclosure statements and applications for the program through
     which you intend to invest.

GENERAL NOTES FOR SELLING SHARES
- -------------------------------------------------------------------------------------------------
We determine the NAV of the funds each day as of the close of regular trading on the NYSE, which
is generally 1:00 PM (Pacific time)/3:00 P.M. (Central time).
- -------------------------------------------------------------------------------------------------
Your redemptions are net of any applicable CDSC.
- -------------------------------------------------------------------------------------------------
We will process requests to sell shares at the first NAV calculated after a request in proper
form is received.  Requests received before the cutoff times are processed on the same business
day.
- -------------------------------------------------------------------------------------------------
If your purchased shares through a packaged investment product or retirement plan, read the
directions for selling shares provided by the product or plan.  There may be special
requirements that supersede the directions in this Prospectus.
- -------------------------------------------------------------------------------------------------
We reserve the right to delay payment of a redemption so that we may be reasonably certain that
investments made by check or Systematic Purchase Plan have been collected.  Payments of
redemptions also may be delayed under extraordinary circumstances or as permitted by the SEC in
order to protect remaining shareholders.
- -------------------------------------------------------------------------------------------------
Generally, we pay redemption requests in cash, unless the redemption request is for more than
$250,000 or 1% of the net assets of the Fund by a single shareholder over any ninety-day
period.  If a request for a redemption is over these limits, it may be to the detriment of
existing shareholders to pay such redemption in cash.  Therefore, we may pay all or part of the
redemption in securities of equal value.

Exchanges

Exchanges between Wells Fargo Funds Trust Funds are two transactions:  a sale of
shares of one Fund and the purchase of shares of another.  In general, the same
rules and procedures that apply to sales and purchases apply to exchanges.
There are, however, additional factors you should keep in mind while making or
considering an exchange:

 .  You should carefully read the Prospectus for the Fund into which you wish to
   exchange.

 .  Every exchange involves selling Fund shares and that sale may produce a
   capital gain or loss for federal income tax purposes.

 .  If you are making an initial investment into a new Fund through an exchange,
   you must exchange at least the minimum first purchase amount of the Fund you
   are redeeming, unless your balance has fallen below that amount due to market
   conditions.

 .  Any exchange between Funds you already own must meet the minimum redemption
   and subsequent purchase amounts for the Funds involved.

 .  Exchanges between Class B shares and the Wells Fargo Money Market Fund Class
   B will not trigger the CDSC. The new shares will continue to age according to
   their original schedule while in the new Fund and will be charged the CDSC
   applicable to the original shares upon redemption. Exchanges into Money
   Market Fund Class B shares are subject to certain restrictions in addition to
   those described above.

 .  Exchanges from any share class to a money market fund can only be re-
   exchanged for the original share class.

 .  In order to discourage excessive Fund transaction expenses that must be borne
   by other shareholders, we reserve the right to limit or reject exchange
   orders. Generally, we will notify you 60 days in advance of any changes in
   your exchange privileges.

 .  You may make exchanges between like share classes.  You may also exchange
   from Class A or Class C shares to any non-institutional money market fund.

Additional Services and Other Information

Automatic Programs:
These programs help you conveniently purchase and/or redeem shares each month.
Call Investor Services 1-800-222-8222 for more information.

 .  Systematic Purchase Plan - With this program, you can regularly purchase
   shares of a Wells Fargo Fund with money automatically transferred from a
   linked bank account. Simply select the Fund you would like to purchase,
   specify an amount of at least $100, and tell us the day of the month you
   would like the money invested. If you do not specify a date, we will transfer
   the money and invest in shares of the Fund you select on or about the 25th
   day of the month.

 .  Systematic Exchange Plan - With this program, you can regularly exchange
   shares of a Wells Fargo Fund you own for shares of another Wells Fargo Fund.
   The exchange amount must be at least $100, and the exchange will take place
   on or about the 25th of each month. See the "Exchanges" section of this
   prospectus for the conditions that apply to your shares. This feature may not
   be available for certain types of accounts.

 .  Systematic Withdrawal Plan - With this program, you can regularly redeem
   shares and receive the proceeds by check or by transfer to a linked bank
   account. Simply specify an amount of at least $100 and we will sell your
   shares equal to that amount on or about the 25th of each month. To
   participate in this program, you:

   .  must have a Fund account value at $10,000 or more;
   .  must have your distributions reinvested; and
   .  may not simultaneously participate in the Systematic Purchase Plan.

It generally takes about ten days to establish a plan once we have received your
instructions.  It generally takes about five days to change or cancel
participation in a plan.  We automatically cancel your program if the linked
bank account your specified is closed.

Dividend and Capital Gain Distributions Options
The Funds in this Prospectus make capital gains distributions at least annually.
The Funds pay any dividends monthly.

We offer the following distribution options:

 .  Automatic Reinvestment Option - Lets you buy new shares of the same class of
   the Fund that generated the distributions. The new shares are purchased at
   NAV generally on the day the income is paid. This option is automatically
   assigned to your account unless you specify another plan.

 .  Check Payment Option - Allows you to receive checks for distributions mailed
   to your address of record or to another name and address which you have
   specified in written, signature guaranteed instructions. If checks remain
   uncashed for six months or are undeliverable by the Post Office, we will
   reinvest the distributions at the earliest date possible.

Two Things to Keep In Mind About Distributions

Remember, distributions have the effect of reducing the NAV per share by the
amount distributed.  Also, distributions on new shares shortly after purchase
would be in effect a return of capital, although the distribution may still be
taxable to you.

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus.  The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder.  It
is not intended as a substitute for careful tax planning.  You should consult
your tax advisor about your specific tax situation.  Federal income tax
considerations are discussed further in the Statement of Additional Information.

Dividends distributed from the Funds attributable to their net interest income
from tax-exempt securities will not be subject to federal income tax.  Dividends
distributed from these and the other Funds attributable to their income from
other investments and net short-term capital gain (generally, the excess of net
short-term capital gains over net long-term capital losses) will be taxable to
you as ordinary income.  Corporate shareholders may be able to deduct a portion
of their dividends when determining their taxable income.

We will pass on to you any net capital gain (generally the excess of net long-
term capital gains over net short-term capital losses) earned by a Fund as a
capital gain distribution.  In general, these distributions will be taxable to
you as long-term capital gains which may qualify for taxation at preferential
rates in the hands of non-corporate shareholders.  Any distribution that is not
from net investment income, short term capital gains, or net capital gain may be
characterized as a return of capital to shareholders.

Table of Predecessors

The Funds described in this Prospectus were created as part of the
reorganization of the Stagecoach Family of Funds, advised by Wells Fargo Bank,
N.A., and the Norwest Advantage Family of Funds, advised by Norwest Investment
Management, Inc., into a single mutual fund complex.  The reorganization

Summary Of Important Risks

 This section summarizes important risks that are common to all of the Funds
 described in this Prospectus, and important risks that relate specifically to
 particular Funds.  Both are important to your investment choice.  Additional
 information about these and other risks is included in the individual Fund
 descriptions later in this Prospectus and under General Investment Risks
 beginning on page __ and in the Fund's Statement of Additional Information.  An
 investment in a Fund is not a deposit of Wells Fargo Bank and is not insured or
 guaranteed by the Federal Deposit Insurance Corporation or any other government
 agency.

 Common Risks for the Funds

 The Funds invest their assets in debt securities, such as notes and bonds,
 which are subject to credit risk and interest rate risk. Credit risk is the
 possibility that an issuer of an instrument will be unable to make interest
 payments or repay principal. Changes in the financial strength of an issuer or
 changes in the credit rating of a security may affect its value. Interest rate
 risk is the risk that interest rates may increase, which will reduce the resale
 value of instruments in a Fund's portfolio, including U.S. Government
 obligations. Debt securities with longer maturities are generally more
 sensitive to interest rate changes than those with shorter maturities. Changes
 in market interest rates do not affect the rate payable on debt instruments
 held in a Fund, unless the instrument has adjustable or variable rate features,
 which can reduce interest rate risk. Changes in market interest rates may also
 extend or shorten the duration of certain types of instruments, such as asset-
 backed securities, thereby affecting their value and the return on your
 investment.

 Tax-Free Funds take advantage of tax laws that allow the income from certain
 investments to be exempted from federal and, in some cases, state personal
 income tax.  Capital gains, whether declared by a Fund or realized by the
 shareholder through the selling of Fund shares, are generally taxable.

 Each Fund (except for National Limited Term Tax-Free Fund) is considered non-
 diversified according to the Investment Company Act of 1940, as amended (the
 "1940 Act").  The majority of the issuers of the securities in the Fund's
 portfolio are located within one state.  Non-diversified, geographically
 concentrated funds are riskier than similar funds that are diversified or
 spread their investments over several geographic areas.  Default by a single
 security in the portfolio may have a greater negative affect than a similar
 default in a diversified portfolio.

 Although we strive to invest in municipal obligations and other securities
 whose interest is exempt from federal income taxes, some distribution income
 earned may be subject to the federal alternative minimum tax ("AMT").

Fund-Specific Risks

 Minnesota Tax-Free Fund

 The Fund may invest up to 25% of its total assets in non-investment grade
 municipal obligations, commonly known as "high yield/high risk securities" or
 "junk bonds," which are considered a more speculative investment than
 investment grade municipal obligations.

 Performance History
 The Funds in this Prospectus will commence operations in September 1999.  No
 performance information is given for the Funds because they will have been in
 operation for less than one year.

Arizona Tax-Free Fund

Investment Objective
The Arizona Tax-Free Fund seeks to provide investors with current income exempt
from federal income tax and Arizona personal income tax.

Investment Policies
We actively manage a portfolio of municipal obligations and we buy municipal
obligations of any maturity length.  The portfolio's weighted average maturity
will vary depending on market conditions, economic conditions including interest
rates, the differences in yields between obligations of different maturity
lengths and other factors.  Generally speaking, we will attempt to capture
greater total return by increasing maturity when we expect interest rates to
decline, and attempt to preserve capital by shortening maturity when interest
rates are expected to increase.

Permitted Investments
Under normal market conditions, we invest:

 .    at least 80% of our assets in municipal obligations that pay interest
     exempt from federal income tax;
 .    at least 65% of our assets in municipal obligations that pay interest
     exempt from Arizona personal income tax; and
 .    in municipal obligations rated in the four highest credit categories by
     nationally recognized rating organizations ("NRRO").

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interests of shareholders
to do so. During such periods, the Fund may not achieve its investment
objective.

Important Risk Factors
The Fund is considered non-diversified according to the Investment Company Act
of 1940 (the "1940 Act").  The majority of the issuers of the securities in the
Fund's portfolio are located within Arizona.  Non-diversified, geographically
concentrated funds are riskier than similar funds that are diversified or spread
their investments over several geographic areas.  Default by a single security
in the portfolio may have a greater negative affect than a similar default in a
diversified portfolio.

Municipal obligations rely on the creditworthiness or revenue production of
their issuers.  Municipal obligations may be difficult to obtain because of
limited supply, which may increase the cost of such securities and effectively
reduce the portfolio's yield.  Typically, less information is available about a
municipal issuer than is available for other types of securities issuers.

You should consider both the General Investment Risks listed on page __ and the
specific risks listed above.  They are equally important to your investment
choice.

California Tax-Free Fund

Investment Objective
The California Tax-Free Fund seeks to provide investors with a high level of
current income exempt from federal income tax and California personal income
tax, while preserving capital, by investing in medium- to long-term investment-
grade municipal securities.

Investment Policies
We actively manage a portfolio of municipal obligations.  We buy municipal
obligations of any maturity length, but we invest substantially all of our
assets in securities with remaining maturities of 2 to 10 years (medium term) or
10 years or longer (long term).  We have some flexibility in setting the
portfolio's dollar-weighted average maturity.  Generally speaking, we will
attempt to capture greater total return by increasing dollar-weighted average
maturity when we expect interest rates to decline, and attempt to preserve
capital by shortening maturity when interest rates are expected to increase.

Permitted Investments
Under normal market conditions, we invest:

 .    at least 80% of our assets in municipal obligations that pay interest
     exempt from federal income tax;
 .    at least 65% of our assets in municipal obligations that pay interest
     exempt from California personal income tax; and
 .    in municipal obligations rated in the four highest credit categories by
     NRROs.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interests of shareholders
to do so. During such periods, the Fund may not achieve its investment
objective.

California Limited Term Tax-Free Fund

Investment Objective
The California Limited Term Tax-Free Fund seeks to provide investors with a high
level of current income exempt from federal income tax and California personal
income tax, while preserving capital.

Investment Policies
We actively manage a portfolio of municipal obligations. We buy municipal
obligations of any maturity length, but we primarily buy securities with
remaining maturities of less than 2 years (short-term) or 2 to 10 years (medium-
term). We have some flexibility in setting the portfolio's dollar-weighted
average maturity. Generally speaking, we will attempt to capture greater total
return by increasing dollar-weighted average maturity when we expect interest
rates to decline, and attempt to preserve capital by shortening maturity when
interest rates are expected to increase. Under normal market conditions, the
average expected duration of the Fund's portfolio securities will be from 1 to 5
years.

Permitted Investments
Under normal market conditions, we invest:

 .    at least 80% of our assets in municipal obligations that pay interest
     exempt from federal income tax;
 .    at least 65% of our assets in municipal obligations that pay interest
     exempt from California personal income tax; and
 .    in municipal obligations rated in the four highest credit categories by
     NRROs.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term

Colorado Tax-Free Fund

Investment Objective
The Colorado Tax-Free Fund seeks to provide investors with a high level of
current income exempt from both federal and Colorado state income taxes
consistent with the preservation of capital. The Fund offers shares only to
residents of Colorado.

Investment Policies
The Fund normally invests substantially all of its assets in investment grade
municipal obligations issued by the state of Colorado and its subdivisions,
authorities, instrumentalities, and corporations; and by the territories and
possessions of the United States.

The Advisor expects that the Fund's average portfolio maturity normally will be
greater than 10 years. The Fund's average portfolio maturity may reach or exceed
20 years in the future. Depending on market conditions, the Fund's dollar-
weighted average maturity could be higher or lower. The Fund emphasizes
investments in municipal obligations paying interest income rather than
maintaining the Fund's stability of net asset value. The Fund also attempts to
limit net asset value fluctuations.

Permitted Investments
As a fundamental policy, the Fund will invest at least 80% of its assets in
municipal obligations paying interest exempt from both federal and Colorado
state income taxes. The Fund invests in securities of a comparatively small
number of issuers. The Fund will not invest more than 25% of its total assets in
securities of related issuers or in securities of any one issuer, except the
U.S. Government.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interests of shareholders
to do so. During such periods, the Fund may not achieve its investment
objective.

Important Risk Factors
All investments in a Fund are subject to risk and may decline in value. The
amount and types of risk vary depending on the Fund's investment objective, the
Advisor's strategy, the markets in which the Fund invests, the investments that
the Fund makes and prevailing economic conditions over the period of your
investment.

The investment income you receive from a Fund will vary with changes in interest
rates. In addition, the value of the Fund's investments generally will fall when
interest rates rise and rise when interest rates fall. When interest rates fall,
there is a risk that issuers will prepay fixed rate securities, forcing the Fund
to invest in securities with lower interest rates than the prepaid securities.

The yields of Colorado municipal obligations depend on, among other things,
conditions in the Colorado municipal obligations market and fixed-income markets
generally, the size of a particular offering, the maturity of the securities,
and the rating of the issue. In some cases, Colorado issues may have yields that
are slightly less than the yields of municipal obligations of issuers located in
other states because of the favorable Colorado state tax exemption on Colorado
issues.

The Fund is considered non-diversified according to the 1940 Act. The majority
of the issuers of the securities in the portfolio are located within Colorado.
Non-diversified, geographically concentrated funds are riskier than similar
funds that are diversified or spread their investments over several geographical
areas. Default by a single security in the portfolio may have a greater negative
affect than a similar default in a diversified portfolio.

Municipal obligations rely on the creditworthiness or revenue production of
their issuers. Municipal obligations may be difficult to obtain because of
limited supply, which may increase the cost of such securities and effectively
reduce the portfolio's yield. Typically, less information is available about a
municipal issuer than is available for other types of securities issuers.

National Limited Term Tax-Free Fund

Investment Objective
The National Limited Term Tax-Free Fund's investment objective is to produce
current income exempt from federal income taxes.

Investment Policies
The Fund normally invests substantially all of its assets in investment grade
municipal obligations. The Fund invests primarily in securities that do not pay
interest that is treated as a preference item for individuals for purposes of
the federal alternative minimum tax.

The average dollar-weighted maturity of the Fund's assets normally will be
between 1 and 5 years, but will vary depending on anticipated market conditions.
The Fund emphasizes investment in municipal obligations with interest income
rather than maintaining stability of the Fund's net asset value.

Permitted Investments
As a fundamental investment policy, the Fund will invest at least 80% of its
total assets in securities paying interest exempt from federal income taxes. The
Fund normally will not invest more than 25% of its total assets in securities of
issuers located in the same state or in related issuers.

In addition, the Fund may hold a portion of its assets in cash and cash-
equivalent securities pending investment in municipal obligations, to meet
requests for redemptions or to assume a temporary defensive position.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interests of shareholders
to do so. During such periods, the Fund may not achieve its investment
objective.

Minnesota Tax-Free Fund

Investment Objective
The Minnesota Tax-Free Fund's investment objective is to provide investors with
a high level of current income exempt from both federal and Minnesota state
income taxes without assuming undue risk. The Fund offers shares only to
residents of Minnesota.

Investment Policies
The Fund normally invests substantially all (and always at least 75% of) its
assets in investment grade municipal obligations issued by the state of
Minnesota and its subdivisions, authorities, instrumentalities, and
corporations; and by the territories and possessions of the United States.

There are no restrictions on Minnesota Tax-Free Fund's average portfolio
maturity. The Advisor expects that the Fund's dollar-weighted average maturity
normally will be greater than 10 years. The Fund's average portfolio maturity
may reach or exceed 20 years in the future. Depending on market conditions, the
Fund's dollar-weighted average maturity could be higher or lower.

U.S. Government.

The Fund may invest up to 25% of its total assets in non-investment grade
municipal obligations.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase

grade securities also tend to be more sensitive to economic conditions than
higher-rated securities. These securities generally involve more credit risk.

Oregon Tax-Free Fund

Investment Objective
The Oregon Tax-Free Fund seeks to provide investors with a high level of current
income exempt from federal income tax and Oregon personal income tax.

Investment Policies
We actively manage a portfolio of municipal obligations and we buy municipal
obligations of any maturity length. The portfolio's weighted average maturity
will vary depending on market conditions, economic conditions including interest
rates, the differences in yields between obligations of different maturity
lengths and other factors. There is no required range for the portfolio's dollar
weighted average maturity. Generally speaking, we will attempt to capture
greater total return by increasing maturity when we expect interest rates to
decline, and attempt to preserve capital by shortening maturity when interest
rates are expected to increase.

Permitted Investments
Under normal market conditions, we invest:

 .  at least 80% of our assets in municipal obligations that pay interest exempt
   from federal income tax;
 .  at least 65% of our assets in municipal obligations that pay interest exempt
   from Oregon personal income tax; and
 .  in municipal obligations rated in the four highest credit categories by
   nationally recognized credit rating organizations.

We may temporarily hold assets in cash or in money market instruments, including
U.S. Government obligations, shares of other mutual funds and repurchase
agreements, or make other short-term investments, including up to 20% of assets
in certain taxable investments, either to maintain liquidity or for short-term
defensive purposes when we believe it is in the best interest of shareholders to
do so. During such periods, the Fund may not achieve its investment objective.

Important Risk Factors
The Fund is considered non-diversified according to the 1940 Act. The majority

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds Trust Funds. Certain common risks are identified
in the Summary of Important Risks on page ___. Other risks of mutual fund
investing include the following:

 .  Unlike bank deposits, such as CDs or savings accounts, mutual funds are not
   insured by the FDIC.
 .  We cannot guarantee that we will meet our investment objectives.
 .  We do not guarantee the performance of a Fund, nor can we assure you that the
   market value of your investment will not decline. We will not "make good" any
   investment loss you may suffer, nor can anyone we contract with to provide
   certain services, such as selling agents or investment advisors, offer or
   promise to make good any such losses.
 .  Share prices -- and therefore the value of your investment -- will increase
   and decrease with changes in the value of the underlying securities and other
   investments.  This is referred to as price volatility.
 .  Investing in any mutual fund, including those deemed conservative, involves
   risk, including the possible loss of any money you invest.
 .  An investment in a single Fund, by itself, does not constitute a complete
   investment plan.
 .  Each Fund may continue to hold debt-instruments that cease to be rated by a
   NRRO or whose ratings fall below the levels generally permitted for such
   Fund, provided Wells Fargo deems the instrument to be of comparable quality
   to rated or higher-rated instruments. Unrated or downgraded instruments may
   be more susceptible to credit and interest rate risks than investment grade
   bonds.
 .  The Funds may invest a portion of their assets in U.S. Government obligations
   such as securities issued or guaranteed by the Government National Mortgage
   Association ("GNMAs"), the Federal National Mortgage Association ("FNMAs")
   and the Federal Home Loan Mortgage Corporation ("FHLMCs"). Each are mortgage-
   backed securities representing partial ownership of a pool of residential
   mortgage loans. A "pool" or group of such mortgages is assembled and, after
   being approved by the issuing or guaranteeing entity, is offered to investors
   through securities dealers. Mortgage-backed securities are subject to
   prepayment and extension risk, which can alter the maturity of the securities
   and also reduce the rate of return on the portfolio. Collateralized mortgage
   obligations ("CMOs") typically represent principal-only and interest-only
   portions of such securities and are subject to increased interest-rate and
   credit risk. It is important to recognize that the U.S. Government does not
   guarantee the market value or current yield of those obligations. Not all
   U.S. Government obligations are backed by the full faith and credit of the
   U.S. Treasury, and the U.S. Government's guarantee does not extend to the
   Funds themselves.
 .  The Funds may also use certain derivative instruments, such as options or
   futures contracts. The term "derivatives" covers a wide number of
   investments, but in general it refers to any financial instrument whose value
   is derived, at least in part, from the price of another security or a
   specified index, asset or rate. Some derivatives may be more sensitive to
   interest rate changes or market moves, and some may be susceptible to changes
   in yields or values due to their structure or contract terms.
 .  The Funds may temporarily hold assets in cash or in money market instruments,
   including U.S. Government obligations, shares of other mutual funds and
   repurchase agreements, or make other short-term investments, either to
   maintain liquidity or for short-term defensive purposes when we believe it is
   in the best interests of shareholders to do so. To the extend a Fund's assets
   are so invested, they may cause a Fund not to achieve its investment
   objective. This practice is expected to have limited, if any, effect on the
   Fund's pursuit of their objectives over the long term.

Investment practices and risk levels are carefully monitored. Every attempt is
made to ensure that the risk exposure for each Fund remains within the
parameters of its objective.

General Investment Risks (Cont'd)

What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Fund and a table showing some of the
additional investment practices that each Fund may use and the risks associated
with them. Additional information about these practices is available in the
Statement of Additional Information.

Counter-Party Risk--The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule. If an issuer does default, the
affected security could lose all of its value, or be renegotiated at a lower
interest rate or principal amount. Affected securities might also lose
liquidity. Credit risk also includes the risk that a party in a transaction may
not be able to complete the transaction as agreed.

Experience Risk--The risk presented by a new or innovative security. The risk is
that insufficient experience exists to forecast how the security's value might
be affected by various economic conditions.

Extension Risk--The risk that an interest rates rise, prepayments slow, thereby
lengthening the duration and potentially reducing the value of certain asset-
backed securities.

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security. Generally, when interest rates increase, the value of a
debt security decreases. The effect is usually more pronounced for securities
with longer dates to maturity.

Leverage Risk--The risk that a practice may increase a Fund's exposure to market
risk, interest rate risk or other risks by, in effect, increasing assets
available for investment.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of a stock, bond or other security will be
reduced by market activity. This is a basic risk associated with all securities.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security. Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Year 2000 Risk--The Funds' principal service providers have advised the Funds
that they are working on the necessary changes to their computer systems to
avoid any system failure based on an inability to distinguish the year 2000 from
the year 1900, and that they expect their systems to be adapted in time. There
can, of course, be no assurance of success. In addition, the companies or
entities in which the Funds invest also could be adversely impacted by the Year
2000 issue, especially foreign entities, which may be less prepared for Year
2000. The extent of such impact cannot be predicted.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund. You should also
see the Statement of Additional Information for additional information about the
investment practices and risks particular to each Fund.

but are among the more prominent. Market risk is assumed for each. See the
Investment Objective and Investment Policies for each Fund or the Statement of
Additional Information for more information on these practices.

ensure that the risk exposure for each Fund remains within the parameters of its
objective.

Organization and Management of the Funds

A number of different entities provide services to the Funds. This section shows
how the Funds are organized, lists the entities that perform different services,
and explains how their service providers are compensated. Further information is
available in the Statement of Additional Information for the Funds.

About Wells Fargo Funds Trust
Wells Fargo Funds Trust (the "Trust") was organized as a Delaware business trust
on March 10, 1999. The Board of Trustees of the Trust supervises each Fund's
activities, monitors its contractual arrangements with various service providers
and decides upon matters of general policy. Each Fund is one of over 60 Funds of
the Trust.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds. The holding company of Wells Fargo Bank, the investment advisor to the
Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998. Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one or more Stagecoach
and/or Norwest Advantage Funds. One of these predecessor funds is expected to be
the "accounting survivor," which means that its performance and financial
statement history will be assumed by the Wells Fargo Funds Trust Fund. The
succession transactions are conditioned on shareholder approval by the
shareholders of the various Stagecoach and Norwest Advantage Funds. The Table on
page __ identifies the expected accounting survivors.

The Board of Trustees of the Trust supervises the Funds' activities and approves
the selection of various companies hired to manage the Funds' operation. The
major service providers are described in the diagram below. Except for the
advisors, which require shareholder vote to change, if the Board believes that
it is in the best interests of the shareholders, it may make a change in one of
these companies.

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:
 .  Read this Prospectus carefully. Discuss any questions you have with your
   Institution. You may also ask for copies of the Statement of Additional
   Information and Annual or Semi-Annual Reports. Copies are available free of
   charge from your Institution or by calling 1-800-260-5969.
 .  As with all mutual fund investments, the price you pay to purchase shares or
   the price you receive when you redeem shares is not determined until after a
   request has been received in proper form.
 .  We determine the Net Asset Value ("NAV") of each Funds' shares each business
   day as of the close of regular trading on the NYSE. We determine the NAV by
   subtracting the liabilities of each Fund from its total assets, and then
   dividing the result by the total number of outstanding shares of that Fund.
   Each Fund's assets are generally valued at current market prices. See the
   Statement of Additional Information for further disclosure.
 .  We process requests to buy or sell shares of the Funds each business day as
   of the close of regular trading on the New York Stock Exchange ("NYSE"),
   which is usually 1:00 p.m. (Pacific time)/3:00 p.m. (Central time). If the
   markets close early, the Funds may close early and may value their shares at
   earlier times under these circumstances. Any request we receive in proper
   form before these times is processed the same day. Requests we receive after
   the cutoff times are processed the next business day.
 .  The Funds are open for business on each day the NYSE is open for business.
   NYSE holidays include New Year's Day, Martin Luther King, Jr. Day,
   President's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
   Thanksgiving Day and Christmas Day. When any holiday falls on a weekend, the
   NYSE typically is closed on the weekday immediately before or after such
   holiday.

Typically, Institutional Class shares are bought and held on your behalf by the
Institution through which you are investing. Check with your customer account
representative or your customer account agreement for the rules governing your
investment.

Minimum Investments:
 .  $2,000,000 per Fund minimum initial investment.

Your Account (Cont'd)

How to Buy Shares
You can open a Fund account and buy Fund shares through an Institution through
which you have established a Customer Account. Investors interested in
purchasing Institutional shares of the Funds should contact an account
representative at their Institution and should understand the following:

 .  Share purchases are made through a Customer Account at an Institution in
   accordance with the terms of the Customer Account involved;
 .  Institutions are usually the holders of record for Institutional shares held
   through Customer Accounts and maintain records reflecting their customers'
   beneficial ownership of the shares;
 .  Institutions are responsible for transmitting their customers' purchase and
   redemption orders to the Funds and for delivering required payment on a
   timely basis;
 .  The exercise of voting rights and the delivery of shareholder communications
   from the Funds is governed by the terms of the Customer Account involved; and
 .  Institutions may charge their customers account fees and may receive fees
   from us with respect to investments their customers have made with the Funds.
   See "Organization and Management of the Funds" for further details about
   these fees.

How to Sell Shares
Institutional shares must be redeemed in accordance with the account agreement
governing your Customer Account at the Institution. Please read the Customer
Account agreement with your Institution for rules governing selling shares.

General notes for selling shares
 .  We process requests we receive from an Institution in proper form before the
   close of the NYSE, usually 1:00 P.M. Pacific time, at the NAV determined on
   the same business day. Requests we receive after this time are processed on
   the next business day.
 .  Redemption proceeds are usually wired to the redeeming Institution the
   following business day.
 .  We reserve the right to delay payment of a redemption for up to 15 days so
   that we may be reasonably certain that investments made by check have been
   collected. Payments of redemptions also may be delayed under extraordinary
   circumstances or as permitted by the SEC in order to protect remaining
   shareholders. Payments of redemptions also may be delayed up to seven days
   under normal circumstances, although it is not our policy to delay such
   payments.
 .  Generally, we pay redemption requests in cash, unless the redemption requests
   is for more than $250,000 or 1% of the net assets of the Fund by a single
   shareholder over a ninety-day period. If a request for a redemption is over
   these limits it may be to the detriment of existing shareholders. Therefore,
   we may pay the redemption in part on in whole in securities of equal value.

Exchanges

Exchanges between Wells Fargo Funds Trust Funds are two transactions: a sale of
shares of one Fund and the purchase of shares of another. In general, the same
rules and procedures that apply to sales and purchases apply to exchanges. There
are, however, additional factors you should keep in mind while making or
considering an exchange:

 .  You should carefully read the Prospectus for the Fund into which you wish to
   exchange.
 .  Every exchange involves selling Fund shares and that sale may produce a
   capital gain or loss for federal income tax purposes.
 .  If you are making an initial investment into a new Fund through an exchange,
   you must exchange at least the minimum first purchase amount of the Fund you
   are redeeming, unless your balance has fallen below that amount due to market
   conditions.
 .  Any exchange between Funds you already own must meet the minimum redemption
   and subsequent purchase amounts for the Funds involved.
 .  In order to discourage excessive Fund transaction expenses that must be borne
   by other shareholders, we reserve the right to limit or reject exchange
   orders. Generally, we will notify you 60 days in advance of any changes in
   your exchange privileges.
 .  You may make exchanges between like share classes. Contact your account
   representative for further details.

Additional Services and Other Information

Dividend and Capital Gain Distributions Options
The Funds in this Prospectus make capital gains distributions at least annually.
The Funds pay any dividends monthly.

Distributions paid by a Fund are automatically reinvested to purchase new shares
of the Funds. The new shares are purchased at NAV, generally on the day
distributions are paid.

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus. The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder. It
is not intended as a substitute for careful tax planning. You should consult
your tax advisor about your specific tax situation. Federal income tax
considerations are discussed further in the Statement of Additional Information.

Dividends distributed from the Funds attributable to their net interest income
from tax-exempt securities will not be subject to federal income tax. Dividends
distributed from these and the other Funds attributable to their income from
other investments and net short-term capital gain (generally, the excess of net
short-term capital gains over net long-term capital losses) will be taxable to
you as ordinary income. Corporate shareholders may be able to deduct a portion
of their dividends when determining their taxable income.

We will pass on to you any net capital gain (generally the excess of net long-
term capital gains over net short-term capital losses) earned by a Fund as a
capital gain distribution. In general, these distributions will be taxable to
you as long-term capital gains which may qualify for taxation at preferential
rates in the hands of non-corporate shareholders. Any distribution that is not
from net investment income, short term capital gains, or net capital gain may be
characterized as a return of capital to shareholders.

                            INVESTMENT RESTRICTIONS

     Fundamental Investment Policies
     -------------------------------

     Each Fund has adopted the following investment restrictions, all of which
are fundamental policies; that is, they may not be changed, without approval by
the holders of a majority (as defined in the Investment Company Act of 1940, as
amended (the "1940 Act")) of the outstanding voting securities of such Fund.

The Funds may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of a Fund's investments in that industry would equal 25% of
the current value of the Fund's total assets, provided that there is no
limitation with respect to investment in securities issued or guaranteed by the
United States Government, its agencies or instrumentalities;

     (2)  purchase securities of any issuer if, as a result, with respect to 75%
of a Fund's total assets, more than 5% of the value of its total assets would be
invested in the securities of any one issuer or, with respect to 100% of its
assets, the Fund's ownership would be more than 10% of the outstanding voting
securities of such issuer.  This policy does not restrict a Fund's ability to
invest in securities issued or guaranteed by the U.S. Government, its agencies
and instrumentalities; or to invest substantially all of its assets in  the
portfolio of one or more open-end management investment companies pursuant to
Section 12 of the 1940 Act and the rules thereunder;

     (3)  borrow money except to the extent permitted by the 1940 Act, and the
rules, regulations and exemptions thereunder;

     (4)  issue senior securities  except to the extent permitted by the 1940
Act, and the rules, regulations and exemptions thereunder;

     (5)  make loans to other parties if, as a result, the aggregate value of
such loans would exceed one-third of a Fund's total assets.  For the purposes of
this limitation, entering into repurchase agreements, lending securities and
acquiring any debt securities are not deemed to be the making of loans;

     (6)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer and

                                       2
<PAGE>

the later disposition of such securities in accordance with a Fund's investment
program may be deemed to be an underwriting;

     (7)  purchase or sell real estate unless acquired as a result of ownership
of securities or other instruments (but this shall not prevent the Fund from
investing in securities or other instruments backed by real estate or securities
of companies engaged in the real estate business); nor

     (8)  purchase or sell physical commodities unless acquired as a result of
ownership of securities or other instruments (but this shall not prevent the
Funds from purchasing or selling options and futures contracts, or from
investing in securities or other instruments backed by physical commodities.

     Non-Fundamental Investment Policies
     -----------------------------------

     Each Fund has adopted the following non-fundamental policies which may be
changed by a vote of a majority of the Trustees of the Trust or at any time
without approval of such Fund's shareholders.

     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of the 1940 Act, the rules thereunder, and
any orders obtained thereunder now or in the future. Funds in a master/feeder or
core/gateway structure, such as the Income Equity Fund, generally invest in the
securities of one or more open-end management investment companies pursuant to
various provisions of the 1940 Act. Other investment companies in which the
Funds invest can be expected to charge fees for operating expenses, such as
investment advisory and administration fees, that would be in addition to those
charged by a Fund.

     (2)  Each Fund may not invest or hold more than 15% of the Fund's net
assets in illiquid securities. For this purpose, illiquid securities include,
among others, (a) securities that are illiquid by virtue of the absence of a
readily available market or legal or contractual restrictions on resale, (b)
fixed time deposits that are subject to withdrawal penalties and that have
maturities of more than seven days, and (c) repurchase agreements not terminable
within seven days.

     (3)  Each Fund may invest in futures or options contracts regulated by the
CFTC for (i) bona fide hedging purposes within the meaning of the rules of the
CFTC and (ii) for other purposes if, as a result, no more than 5% of the Fund's
net assets would be invested in initial margin and premiums (excluding amounts
"in-the-money") required to establish the contracts.

          Each Fund (i) will  not hedge more than [50%] of its total assets by
selling futures contracts, buying put options, and writing call options (so
called "short positions"),  (ii) will not buy futures contracts or write put
options whose underlying value exceeds [25%] of the Fund's total assets, and
(iii) will not buy call options with a value exceeding [5%] of the Fund's total
assets.

                                       3
<PAGE>

     (4)  Each Fund may lend securities from its portfolio to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) up to
the limits established by and under the 1940 Act, including any exemptive relief
obtained thereunder, which limits are currently generally one-third of a Fund's
total assets. Any such loans of portfolio securities will be fully
collateralized based on values that are marked to market daily. A Fund will not
enter into any portfolio security lending arrangement having a duration of
longer than one year.

     (5)  Each Fund may not make investments for the purpose of exercising
control or management. (Investments by the Fund in entities created under the
laws of foreign countries solely to facilitate investment in securities in that
country will not be deemed the making of investments for the purpose of
exercising control.)

     (6)  Each Fund may not purchase securities on margin (except for short-term
credits necessary for the clearance of transactions).

     (7)  Each Fund may not sell securities short, unless it owns or has the
right to obtain securities equivalent in kind and amount to the securities sold
short (short sales "against the box"), and provided that transactions in futures
contracts and options are not deemed to constitute selling securities short.

     (8)  Each Fund may not purchase interests, leases, or limited partnership
interests in oil, gas, or other mineral exploration or development programs.

        ADDITIONAL PERMITTED INVESTMENT ACTIVITIES AND ASSOCIATED RISKS

     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

     Asset-Backed Securities
     -----------------------

     The Funds may invest in various types of asset-backed securities.  Asset-
backed securities are securities that represent an interest in an underlying
security.  The asset-backed securities in which the Funds invest may consist of
undivided fractional interests in pools of consumer loans or receivables held in
trust. Examples include certificates for automobile receivables (CARS) and
credit card receivables (CARDS). Payments of principal and interest on these
asset-backed securities are "passed through" on a monthly or other periodic
basis to certificate holders and are typically supported by some form of credit
enhancement, such as a surety bond, limited guaranty, or subordination. The
extent of credit enhancement varies, but usually amounts to only a fraction of
the asset-backed security's par value until exhausted. Ultimately, asset-backed
securities are dependent upon payment of the consumer loans or receivables by
individuals, and the certificate holder frequently has no recourse to the entity
that originated the loans or receivables. The actual maturity and realized yield
will vary based upon the prepayment experience of the underlying asset pool and
prevailing interest rates at the time of prepayment. Asset-backed securities are
relatively new instruments and may be subject to greater risk of default during
periods of economic downturn than other instruments. Also, the secondary market
for certain asset-backed securities may not be as liquid as the market for other
types of securities, which could result in a Fund experiencing

                                       4
<PAGE>

difficulty in valuing or liquidating such securities. The Funds may also invest
in securities backed by pools of mortgages. The investments are described under
the heading "Mortgage-Related Securities."

     Bank Obligations
     ----------------

     The Funds may invest in bank obligations, including certificates of
deposit, time deposits, bankers' acceptances and other short-term obligations of
domestic banks, foreign subsidiaries of domestic banks, foreign branches of
domestic banks, and domestic and foreign branches of foreign banks, domestic
savings and loan associations and other banking institutions.  With respect to
such securities issued by foreign branches of domestic banks, foreign
subsidiaries of domestic banks, and domestic and foreign branches of foreign
banks, a Fund may be subject to additional investment risks that are different
in some respects from those incurred by a Fund which invests only in debt
obligations of U.S. domestic issuers.  Such risks include possible future
political and economic developments, the possible imposition of foreign
withholding taxes on interest income payable on the securities, the possible
establishment of exchange controls or the adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and interest
on these securities and the possible seizure or nationalization of foreign
deposits.  In addition, foreign branches of U.S. banks and foreign banks may be
subject to less stringent reserve requirements and to different accounting,
auditing, reporting and recordkeeping standards than those applicable to
domestic branches of U.S. banks.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate.  Time
deposits which may be held by a Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation ("FDIC").  Bankers' acceptances are
credit instruments evidencing the obligation of a bank to pay a draft drawn on
it by a customer.  These instruments reflect the obligation both of the bank and
of the drawer to pay the face amount of the instrument upon maturity.  The other
short-term obligations may include uninsured, direct obligations, bearing fixed,
floating- or variable-interest rates.

     Bonds
     -----

     Certain of the debt instruments purchased by the Funds may be bonds.  The
Funds invests no more than 25% in bonds that are below investment grade.  A bond
is an interest-bearing security issued by a company or governmental unit. The
issuer of a bond has a contractual obligation to pay interest at a stated rate
on specific dates and to repay principal (the bond's face value) periodically or
on a specified maturity date. An issuer may have the right to redeem or "call" a
bond before maturity, in which case the investor may have to reinvest the
proceeds at lower market rates.  The value of fixed-rate bonds will tend to fall
when interest rates rise and rise when interest rates fall.  The value of
"floating-rate" or "variable-rate" bonds, on the other hand, fluctuate much less
in response to market interest rate movements than the value of fixed rate
bonds.

                                       5
<PAGE>

     Bonds may be senior or subordinated obligations. Senior obligations
generally have the first claim on a corporation's earnings and assets and, in
the event of liquidation, are paid before subordinated debt. Bonds may be
unsecured (backed only by the issuer's general creditworthiness) or secured
(also backed by specified collateral).

     Commercial Paper
     ----------------

     The Funds may invest in commercial paper (including variable amount master
demand notes) which refers to short-term, unsecured promissory notes issued by
corporations to finance short-term credit needs. Commercial paper is usually
sold on a discount basis and has a maturity at the time of issuance not
exceeding nine months. Variable amount master demand notes are demand
obligations which permit the investment of fluctuating amounts at varying market
rates of interest pursuant to arrangements between the issuer and a commercial
bank acting as agent for the payee of such notes whereby both parties have the
right to vary the amount of the outstanding indebtedness on the notes.
Investments by the Funds in commercial paper (including variable rate demand
notes and variable rate master demand notes issued by domestic and foreign bank
holding companies, corporations and financial institutions, as well as similar
instruments issued by government agencies and instrumentalities) will consist of
issues that are rated in one of the two highest rating categories by a
Nationally Recognized Ratings Organization ("NRRO").  Commercial paper may
include variable- and floating-rate instruments.

     Convertible Securities
     ----------------------

     The Funds may invest in convertible securities.  A convertible security is
generally a debt obligation or preferred stock that may be converted within a
specified period of time into a certain amount of common stock of the same or a
different user.  A convertible security provides a fixed-income stream and the
opportunity, through its conversion feature, to participate in the capital
appreciation resulting from a market price advance in its underlying common
stock.  As with a straight fixed-income security, a convertible security tends
to increase in market value when interest rates decline and decrease in value
when interest rates rise.  Like a common stock, the value of a convertible
security also tends to increase as the market value of the underlying stock
rises, and it tends to decrease as the market value of the underlying stock
declines.  Because its value can be influenced by both interest rate and market
movements, a convertible security is not as sensitive to interest rats as a
similar fixed-income security, nor is it as sensitive to changes in share price
as its underlying stock.

     The creditworthiness of the issuer of a convertible security may be
important in determining the security's true value.  This is because the holder
of a convertible security will have recourse only to the issuer.  In addition, a
convertible security may be subject to redemption by the issuer, but only after
a specified date and under circumstances established at the time the security is
issued.

     While the Funds use the same criteria to rate a convertible debt security
that it uses to rate a more conventional debt security, a convertible preferred
stock is treated like a preferred stock for a Funds' financial reporting, credit
rating, and investment limitation purposes.  A preferred stock is subordinated
to all debt obligations in the event of insolvency, and an issuer's failure to
make a dividend payment is generally not an event of default entitling the
preferred shareholder

                                       6
<PAGE>

to take action. A preferred stock generally has no maturity date, so that its
market value is dependent on the issuer's business prospects for an indefinite
period of time. In addition, distributions from preferred stock are dividends,
rather than interest payments, and are usually treated as such for corporate tax
purposes.

     Derivative Securities
     ---------------------

     The Funds may invest in various instruments that may be considered
"derivatives," including structured notes, bonds or other instruments with
interest rates that are determined by reference to changes in the value of other
interest rates, indices or financial indicators ("References") or the relative
change in two or more References.  Some derivative securities represent
relatively recent innovations in the bond markets, and the trading market for
these instruments is less developed than the markets for traditional types of
debt instruments. It is uncertain how these instruments will perform under
different economic and interest rate scenarios. Because certain of these
instruments are leveraged, their market values may be more volatile than other
types of bonds and may present greater potential for capital gain or loss.
Derivative securities and their underlying instruments may experience periods of
illiquidity, which could cause a Fund to hold a security it might otherwise sell
or could force the sale of a security at inopportune times or for prices that do
not reflect current market value. The possibility of default by the issuer or
the issuer's credit provider may be greater for these structured and derivative
instruments than for other types of instruments.  As new types of derivative
securities are developed and offered to investors, the advisor will, consistent
with the Funds' investment objective, policies and quality standards, consider
making investments in such new types of derivative securities.

     Diversification
     ---------------

     The Funds are non-diversified, which means that they have greater latitude
than a diversified fund with respect to the investment of their assets in the
securities of relatively few municipal issuers.  As non-diversified portfolios,
these Funds may present greater risks than a diversified fund.  However, each
Fund intends to comply with applicable diversification requirements of the
Internal Revenue Code.  These requirements provide that, as of the last day of
each fiscal quarter:  (1) with respect to 50% of its assets, a Fund may not:
(a) own the securities of a single issuer, other than a U.S. Government
security, with a value of more than 5% of the Fund's total assets; or (b) own
more than 10% of the outstanding voting securities of a single issuer; and (2) a
Fund may not own the securities of a single issuer, other than a U.S. Government
security, with a value of more than 25% of the Fund's total assets.

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds may purchase floating- and variable-rate obligations such as
demand notes and bonds.  Variable-rate demand notes include master demand notes
that are obligations that permit a Fund to invest fluctuating amounts, which may
change daily without penalty, pursuant to direct arrangements between the Fund,
as lender, and the borrower.  The interest rate on a floating-rate demand
obligation is based on a known lending rate, such as a bank's prime rate, and is
adjusted automatically each time such rate is adjusted.  The interest rate on a
variable-rate demand obligation is adjusted automatically at specified
intervals.  The issuer of such obligations

                                       7
<PAGE>

ordinarily has a right, after a given period, to prepay in its discretion the
outstanding principal amount of the obligations plus accrued interest upon a
specified number of days' notice to the holders of such obligations. Frequently,
such obligations are secured by letters of credit or other credit support
arrangements provided by banks.

     There generally is no established secondary market for these obligations
because they are direct lending arrangements between the lender and borrower.
Accordingly, where these obligations are not secured by letters of credit or
other credit support arrangements, a Fund's right to redeem is dependent on the
ability of the borrower to pay principal and interest on demand.  Such
obligations frequently are not rated by credit rating agencies and each Fund may
invest in obligations which are not so rated only if the Advisor determines that
at the time of investment the obligations are of comparable quality to the other
obligations in which such Fund may invest. The Advisor, on behalf of each Fund,
considers on an ongoing basis the creditworthiness of the issuers of the
floating- and variable-rate demand obligations in such Fund's portfolio.  No
Fund will invest more than 15% of the value of its total net assets in floating-
or variable-rate demand obligations whose demand feature is not exercisable
within seven days.  Such obligations may be treated as liquid, if an active
secondary market exists.  Floating- and variable-rate instruments are subject to
interest-rate risk and credit risk.

     The floating- and variable-rate instruments that the Funds may purchase
include certificates of participation in such instruments.

     Forward Commitment, When-Issued and Delayed-Delivery Transactions
     -----------------------------------------------------------------

     The Funds may purchase or sell securities on a when-issued or delayed
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time.  Delivery and payment
on such transaction normally take place within 120 days after the date of the
commitment to purchase.  Securities purchased or sold on a when-issued, delayed-
delivery or forward commitment basis involve a risk of loss if the value of the
security to be purchased declines, or the value of the security to be sold
increases, before the settlement date.  The Funds will establish a segregated
account in which they will maintain cash, U.S. Government obligations or other
high-quality debt instruments in an amount at least equal in value to each such
Fund's commitments to purchase when-issued securities. If the value of these
assets declines, a Fund will place additional liquid assets in the account on a
daily basis so that the value of the assets in the account is equal to the
amount of such commitments.

     High Yield/Junk Bonds
     ---------------------

     The Minnesota Tax-Free and Intermediate Tax-Free Funds may invest in bonds
rated below "Baa" by Moody's or "BBB" by S&P (commonly known was "high
yield/high risk securities" or "junk bonds").  Securities rated less than "Baa"
by Moody's or "BBB" by S&P are classified as non-investment grade securities and
are considered speculative by those rating agencies.  Junk bonds may be issued
as a consequence of corporate restructuring, such as leveraged buyouts, mergers,
acquisitions, debt recapitalizations, or similar events or by smaller or highly
leveraged companies.  Although the growth of the high yield/high risk securities
market in the 1980's had paralleled a long economic expansion, many issuers
subsequently have been affected by adverse economic and market conditions.  It
should be recognized that an economic downturn

                                       8
<PAGE>

or increase in interest rates is likely to have a negative effect on: (1) the
high yield bond market; (2) the value of high yield/high risk securities; and
(3) the ability of the securities' issuers to service their principal and
interest payment obligations, to meet their projected business goals or to
obtain additional financing. In addition, the market for high yield/high risk
securities, which is concentrated in relatively few market makers, may not be as
liquid as the market for investment grade securities.

     Geographic Concentration
     ------------------------

     The Funds (except for the National Limited Term Tax-Free Fund) invest
principally in municipal securities issued by issuers within a particular state
and the state's political subdivisions.  Those Funds are more susceptible to
factors adversely affecting issuers of those municipal securities than would be
a more geographically diverse municipal securities portfolio.  These risks arise
from the financial condition of the state and its political subdivisions.  To
the extent state or local governmental entities are unable to meet their
financial obligations, the income derived by a Fund, its ability to preserve or
realize appreciation of its portfolio assets or its liquidity could be impaired.

     To the extent a Fund's investments are primarily concentrated in issuers
located in a particular state, the value of the Fund's shares may be especially
affected by factors pertaining to that state's economy and other factors
specifically affecting the ability of issuers of that state to meet their
obligations.  As a result, the value of the Fund's assets may fluctuate more
widely than the value of shares of a portfolio investing in securities relating
to a number of different states.  The ability of state, county or local
governments and quasi-government agencies to meet their obligations will depend
primarily on the availability of tax and other revenues to those governments and
on their fiscal conditions generally.  The amounts of tax and other revenues
available to governmental issuers may be affected from time to time by economic,
political and demographic conditions within their state.  In addition,
constitutional or statutory restrictions may limit a government's power to raise
revenues or increase taxes.  The availability of federal, state and local aid to
governmental issuers may also affect their ability to meet obligations.
Payments of principal of and interest on private activity securities will depend
on the economic condition of the facility specific revenue source from whose
revenues the payments will be made, which in turn, could be affected by
economic, political or demographic conditions in the state.

     Illiquid Securities
     -------------------

     The Funds may invest in securities not registered under the Securities Act
of 1933, as amended (the "1933 Act") and other securities subject to legal or
other restrictions on resale. Because such securities may be less liquid than
other investments, they may be difficult to sell promptly at an acceptable
price. Delay or difficulty in selling securities may result in a loss or be
costly to a Fund.  Each Fund may invest up to 15% of its net assets in illiquid
securities.

     Loans of Portfolio Securities
     -----------------------------

     Each Fund may lend its portfolio securities to brokers, dealers and
financial institutions, provided: (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at

                                       9
<PAGE>

least equal to the current market value of the securities loaned; (2) such Fund
may at any time call the loan and obtain the return of the securities loaned
within five business days; (3) such Fund will receive any interest or dividends
paid on the loaned securities; and (4) the aggregate market value of securities
loaned will not at any time exceed the limits established by the 1940 Act.

     A Fund will earn income for lending its securities because cash collateral
pursuant to these loans will be invested in short-term money market instruments.
In connection with lending securities, a Fund may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide additional collateral. In either case, a Fund could experience delays
in recovering securities or collateral or could lose all or part of the value of
the loaned securities.  Although voting rights, or rights to consent, attendant
to securities on loan pass to the borrower, such loans may be called at any time
and will be called so that the securities may be voted by a Fund if a material
event affecting the investment is to occur.  A Fund may pay a portion of the
interest or fee earned from securities lending to a borrower or a placing
broker.  Borrowers and placing brokers may not be affiliated, directly or
indirectly with Wells Fargo Bank, Stephens or any of their affiliates.

     Mortgage-Related Securities
     ---------------------------

     The Funds may invest in mortgage-related securities.  Mortgage pass-through
securities are securities representing interests in "pools" of mortgages in
which payments of both interest and principal on the securities are made
monthly, in effect "passing through" monthly payments made by the individual
borrowers on the residential mortgage loans which underlie the securities (net
of fees paid to the issuer or guarantor of the securities).  Payment of
principal and interest on some mortgage pass-through securities (but not the
market value of the securities themselves) may be guaranteed by the full faith
and credit of the U.S. Government or its agencies or instrumentalities.
Mortgage pass-through securities created by non- government issuers (such as
commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers) may be supported
by various forms of insurance or guarantees, including individual loan, title,
pool and hazard insurance, and letters of credit, which may be issued by
governmental entities, private insurers or the mortgage poolers.

     Prepayment Risk.  The stated maturities of mortgage-related securities may
be shortened by unscheduled prepayments of principal on the underlying
mortgages.  Therefore, it is not possible to predict accurately the average
maturity of a particular mortgage-related security .  Variations in the
maturities of mortgage-related securities will affect the yield of the Fund.
Early repayment of principal on mortgage-related securities may expose a Fund to
a lower rate of return upon reinvestment of principal. Also, if a security
subject to prepayment has been purchased at a premium, in the event of
prepayment the value of the premium would be lost. Like other fixed-income
securities, when interest rates rise, the value of a mortgage-related security
generally will decline; however, when interest rates decline, the value of
mortgage-related securities with prepayment features may not increase as much as
other fixed-income securities.

     Collateralized Mortgage Obligations ("CMOs") and Adjustable Rate Mortgages
("ARMs").  The Funds may also invest in investment grade CMOs.  CMOs may be
collateralized by whole mortgage loans but are more typically collateralized by
portfolios of mortgage

                                       10
<PAGE>

pass-through securities guaranteed by the Government National Mortgage
Association ("GNMA"), the Federal Home Loan Mortgage Corporation ("FHLMC") or
Federal National Mortgage Association ("FNMA"). CMOs are structured into
multiple classes, with each class bearing a different stated maturity. Payments
of principal, including prepayments, are first returned to investors holding the
shortest maturity class; investors holding the longer maturity classes receive
principal only after the first class has been retired. As new types of mortgage-
related securities are developed and offered to investors, the Advisor will,
consistent with the Fund's investment objective, policies and quality standards,
consider making investments in such new types of mortgage-related securities.

     The Funds each may invest in ARMs issued or guaranteed by the GNMA, FNMA or
the FHLMC.  The full and timely payment of principal and interest on GNMA ARMs
is guaranteed by GNMA and backed by the full faith and credit of the U.S.
Government.  FNMA also guarantees full and timely payment of both interest and
principal, while FHLMC guarantees full and timely payment of interest and
ultimate payment of principal. FNMA and FHLMC ARMs are not backed by the full
faith and credit of the United States. However, because FNMA and FHLMC are
government-sponsored enterprises, these securities are generally considered to
be high quality investments that present minimal credit risks. The yields
provided by these ARMs have historically exceeded the yields on other types of
U.S. Government securities with comparable maturities, although there can be no
assurance that this historical performance will continue.

     The mortgages underlying ARMs guaranteed by GNMA are typically insured or
guaranteed by the Federal Housing Administration, the Veterans Administration or
the Farmers Home Administration, while those underlying ARMs issued by FNMA or
FHLMC are typically conventional residential mortgages which are not so insured
or guaranteed, but which conform to specific underwriting, size and maturity
standards.

     The interest rates on the mortgages underlying the ARMs and some of the
CMOs in which the Funds may invest generally are readjusted at periodic
intervals ranging from one year or less to several years in response to changes
in a predetermined commonly-recognized interest rate index.  The adjustable rate
feature should reduce, but will not eliminate, price fluctuations in such
securities, particularly when market interest rates fluctuate.  The net asset
value of a Funds' shares may fluctuate to the extent interest rates on
underlying mortgages differ from prevailing market interest rates during interim
periods between interest rate reset dates. Accordingly, investors could
experience some loss if they redeem their shares of a Fund or if the Funds sells
these portfolio securities before the interest rates on the underlying mortgages
are adjusted to reflect prevailing market interest rates.  The holder of ARMs
and CMOs are also subject to repayment risk.

     The Funds will not invest in CMOs that, at the time of purchase, are "high-
risk mortgage securities" as defined in the then current Federal Financial
Institutions Examination Council Supervisory Policy Statement on Securities
Activities.  High-risk mortgage securities are generally those with long
durations or those which are likely to be more sensitive to interest-rate
fluctuations.

     Mortgage Participation Certificates.  The Short-Intermediate U.S.
Government Income Fund and Intermediate Government Income Fund also may invest
in the following types of FHLMC mortgage pass-through securities.  FHLMC issues
two types of mortgage pass-through securities: mortgage participation
certificates ("PCs") and guaranteed mortgage certificates

                                       11
<PAGE>

("GMCs"). PCs resemble GNMA certificates in that each PC represents a pro rata
share of all interest and principal payments made and owed on the underlying
pool of mortgages. GMCs also represent a pro rata interest in a pool of
mortgages. These instruments, however, pay interest semiannually and return
principal once a year in guaranteed minimum payments. These mortgage pass-
through securities differ from bonds in that principal is paid back by the
borrower over the length of the loan rather than returned in a lump sum at
maturity. They are called "pass-through" securities because both interest and
principal payments, including prepayments, are passed through to the holder of
the security. PCs and GMCs are both subject to prepayment risk.

     Other Investment Companies
     --------------------------

     The Funds (except for the Colorado Tax-Free Fund, Minnesota Intermediate
Tax-Free Fund and Minnesota Tax-Free Fund) may invest in shares of other open-
end management investment companies, up to the limits prescribed in Section
12(d) of the 1940 Act.  Under the 1940 Act, a Fund's investment in such
securities currently is limited to, subject to certain exceptions, (i) 3% of the
total voting stock of any one investment company, (ii) 5% of such Fund's net
assets with respect to any one investment company and (iii) 10% of such Fund's
net assets in aggregate.  Other investment companies in which the Funds invest
can be expected to charge fees for operating expenses, such as investment
advisory and administration fees, that would be in addition to those charged by
the Funds.

     Repurchase Agreements.
     ---------------------

     Each Fund may enter into repurchase agreements, wherein the seller of a
security to a Fund agrees to repurchase that security from a Fund at a mutually
agreed upon time and price.  A Fund may enter into repurchase agreements only
with respect to securities that could otherwise be purchased by such Fund.  All
repurchase agreements will be fully collateralized at 102% based on values that
are marked to market daily.  The maturities of the underlying securities in a
repurchase agreement transaction may be greater than twelve months, although the
maximum term of a repurchase agreement will always be less than twelve months.
If the seller defaults and the value of the underlying securities has declined,
a Fund may incur a loss.  In addition, if bankruptcy proceedings are commenced
with respect to the seller of the security, the Funds' disposition of the
security may be delayed or limited.

     A Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 15% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities.  A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Trustees and that are not affiliated with the investment advisor.  The
Funds may participate in pooled repurchase agreement transactions with other
funds advised by Wells Fargo Bank.

     Stripped Securities
     -------------------

     The Funds may purchase Treasury receipts, securities of government-
sponsored enterprises (GSEs), and other "stripped" securities that evidence
ownership in either the future interest payments or the future principal
payments on U.S. Government and other obligations.  The

                                       12
<PAGE>

stripped securities the Funds may purchase are issued by the U.S. Government (or
a U.S. Government agency or instrumentality) or by private issuers such as
banks, corporations and other institutions at a discount to their face value.
The Funds will not purchase stripped mortgage-backed securities ("SMBS"). The
stripped securities purchased by the Funds generally are structured to make a
lump-sum payment at maturity and do not make periodic payments of principal or
interest. Hence, the duration of these securities tends to be longer and they
are therefore more sensitive to interest rate fluctuations than similar
securities that offer periodic payments over time. The stripped securities
purchased by the Funds are not subject to prepayment or extension risk.

     The Funds may purchase participations in trusts that hold U.S. Treasury
securities (such as TIGRs and CATS) or other obligations where the trust
participations evidence ownership in either the future interest payments or the
future principal payments on the obligations. These participations are normally
issued at a discount to their "face value," and can exhibit greater price
volatility than ordinary debt securities because of the way in which their
principal and interest are returned to investors. Investments by the Funds in
such participations will not exceed 5% of the value of the Funds' total assets.

     Reverse Repurchase Agreements.
     -----------------------------

     The Funds intend to limit their borrowings (including reverse repurchase
agreements) during the current fiscal year to not more than 10% of net assets.
At the time a Fund enters into a reverse repurchase agreement (an agreement
under which a Fund sells their portfolio securities and agrees to repurchase
them at an agreed-upon date and price), it will place in a segregated custodial
account liquid assets such as U.S. Government securities or other liquid high-
grade debt securities having a value equal to or greater than the repurchase
price (including accrued interest) and will subsequently monitor the account to
ensure that such value is maintained.  Reverse repurchase agreements involve the
risk that the market value of the securities sold by the Funds may decline below
the price at which the Funds are obligated to repurchase the securities. Reverse
repurchase agreements are considered to be borrowings under the 1940 Act.

     Municipal Bonds
     ---------------

     The Funds may invest in municipal bonds.  The two principal classifications
of municipal bonds are "general obligation" and "revenue" bonds.  Municipal
bonds are debt obligations issued to obtain funds for various public purposes.
Industrial development bonds are a specific type of revenue bond backed by the
credit and security of a private user.  Certain types of industrial development
bonds are issued by or on behalf of public authorities to obtain funds to
provide privately-operated facilities.  The Funds may not invest 20% or more of
their respective assets in industrial development bonds.

     From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal obligations. For example, under federal tax legislation
enacted in 1986, interest on certain private activity bonds must be included in
an investor's alternative minimum taxable income, and corporate investors must
treat all tax-exempt interest as an item of tax preference.  Moreover the Fund
cannot predict what legislation, if any, may be proposed in the state
legislature regarding the state income

                                       13
<PAGE>

tax status of interest on such obligations, or which proposals, if any, might be
enacted. Such proposals, while pending or if enacted, might materially and
adversely affect the availability of municipal obligations generally for
investment by the Fund and the liquidity and value of the Fund's portfolio. In
such an event, the Fund would re-evaluate its investment objective and policies
and consider possible changes in its structure or possible dissolution.

     Certain of the municipal obligations held by the Fund may be insured as to
the timely payment of principal and interest. The insurance policies usually are
obtained by the issuer of the municipal obligation at the time of its original
issuance. In the event that the issuer defaults on interest or principal
payment, the insurer will be notified and will be required to make payment to
the bondholders. There is, however, no guarantee that the insurer will meet its
obligations. In addition, such insurance does not protect against market
fluctuations caused by changes in interest rates and other factors.

     Municipal Notes
     ---------------

     The Funds may invest in municipal notes.  Municipal notes include, but are
not limited to, tax anticipation notes ("TANs"), bond anticipation notes
("BANs"), revenue anticipation notes ("RANs") and construction loan notes.
Notes sold as interim financing in anticipation of collection of taxes, a bond
sale or receipt of other revenues are usually general obligations of the issuer.

     TANs.  An uncertainty in a municipal issuer's capacity to raise taxes as a
result of such events as a decline in its tax base or a rise in delinquencies
could adversely affect the issuer's ability to meet its obligations on
outstanding TANs.  Furthermore, some municipal issuers mix various tax proceeds
into a general fund that is used to meet obligations other than those of the
outstanding TANs.  Use of such a general fund to meet various obligations could
affect the likelihood of making payments on TANs.

     BANs.  The ability of a municipal issuer to meet its obligations on its
BANs is primarily dependent on the issuer's adequate access to the longer term
municipal bond market and the likelihood that the proceeds of such bond sales
will be used to pay the principal of, and interest on, BANs.

     RANs.  A decline in the receipt of certain revenues, such as anticipated
revenues from another level of government, could adversely affect an issuer's
ability to meet its obligations on outstanding RANs.  In addition, the
possibility that the revenues would, when received, be used to meet other
obligations could affect the ability of the issuer to pay the principal of, and
interest on, RANs.

     The values of outstanding municipal securities will vary as a result of
changing market evaluations of the ability of their issuers to meet the interest
and principal payments (i.e., credit risk).  Such values also will change in
response to changes in the interest rates payable on new issues of municipal
securities (i.e., market risk).  Changes in the value of municipal securities
held in the Fund's portfolio arising from these or other factors will cause
changes in the net asset value per share of the Fund.

                                       14
<PAGE>

     U.S. Government Obligations
     ---------------------------

     The Funds may invest in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Obligations").
Payment of principal and interest on U.S. Government Obligations (i) may be
backed by the full faith and credit of the United States (as with U.S. Treasury
bills and GNMA certificates) or (ii) may be backed solely by the issuing or
guaranteeing agency or instrumentality itself (as with FNMA notes). In the
latter case investors must look principally to the agency or instrumentality
issuing or guaranteeing the obligation for ultimate repayment, which agency or
instrumentality may be privately owned. There can be no assurance that the U.S.
Government will provide financial support to its agencies or instrumentalities
where it is not obligated to do so. In addition, U.S. Government Obligations are
subject to fluctuations in market value due to fluctuations in market interest
rates. As a general matter, the value of debt instruments, including U.S.
Government Obligations, declines when market interest rates increase and rises
when market interest rates decrease. Certain types of U.S. Government
Obligations are subject to fluctuations in yield or value due to their structure
or contract terms.

     Zero Coupon Bonds
     -----------------

     The Funds may invest in zero coupon bonds.  Zero coupon bonds are
securities that make no periodic interest payments, but are instead sold at
discounts from face value.  The buyer of such a bond receives the rate of return
by the gradual appreciation of the security, which is redeemed at face value on
a specified maturity date.  Because zero coupon bonds bear no interest, they are
more sensitive to interest-rate changes and are therefore more volatile.  When
interest rates rise, the discount to face value of the security deepens and the
securities decrease more rapidly in value, when interest rates fall, zero coupon
securities rise more rapidly in value because the bonds carry fixed interest
rates that become more attractive in a falling interest rate environment.

     Nationally Recognized Ratings Organizations
     -------------------------------------------

     The ratings of Moody's, S&P, Division of McGraw Hill, Duff & Phelps Credit
Rating Co., Fitch Investors Service, Inc. Thomson Bank Watch and IBCA Inc.
represent their opinions as to the quality of debt securities. It should be
emphasized, however, that ratings are general and not absolute standards of
quality, and debt securities with the same maturity, interest rate and rating
may have different yields while debt securities of the same maturity and
interest rate with different ratings may have the same yield.  Subsequent to
purchase by the Funds, an issue of debt securities may cease to be rated or its
rating may be reduced below the minimum rating required for purchase by the
Funds.  The Advisor will consider such an event in determining whether the Fund
involved should continue to hold the obligation.

        SPECIAL CONSIDERATIONS AFFECTING ARIZONA MUNICIPAL OBLIGATIONS

     The concentration of the Arizona Tax-Free Fund in securities issued by
governmental units of only one state exposes the Fund to risks greater than
those of a more diversified portfolio holding securities issued by governmental
units of different states and different regions of the country.

                                       15

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

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

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

     Arizona is required by law to maintain a balanced budget. To achieve this
objective, the State has, at various times in the past, utilized a combination
of spending reductions or reductions in the rate of growth in spending, and tax
increases.  In recent years, the State's fiscal situation has improved even
while tax reduction measures have been enacted each year since 1992.  In 1992,
Arizona voters passed a measure that requires a two-thirds vote of the
legislature to increase state revenue. Accordingly, it will be more difficult to
reverse tax reductions, which may adversely affect state fund balances and
fiscal conditions over time.

     Arizona state government tax revenue growth in fiscal year 1997 increased
by 6.5% over fiscal year 1996, even after factoring in tax reductions.  The 5.1%
increase in sales tax revenue for FY 1997, and projected increases of 5.0% for
FY 1998 and FY 1999, respectively, reflect continued strong economic growth in
the state.  The state general fund ended fiscal year 1997 with a total general
fund balance of approximately $762 million, representing approximately 16% of
total general fund expenditures for fiscal year 1997.  Included in the total
balance is a general fund ending balance of approximately $516 million, and a
budget stabilization ("rainy day") fund balance of approximately $246 million.
The total general fund balance at the end of fiscal year 1998 is projected to be
approximately $814 million.  While these balances are indicative of present
fiscal health, the overall fiscal picture could change rapidly and dramatically
for the worse, depending on fluctuations in revenues resulting from an economic
recession or other adverse conditions.

     The 1998 legislature enacted a $120 million tax reduction package,
resulting in the seventh consecutive year of significant state tax reduction.
In earlier years, the 1997 legislature

                                       16
<PAGE>

enacted a $110 million income tax reduction package, the 1996 legislature
enacted a $200 million property tax reduction package, and an income tax
reduction of $200 million was enacted in 1995. Although the 1998 general
election ballot will not include questions related to the state tax structure
generally, efforts were made to bring such issues to the ballot, and may be made
again in 2000 and in future years.

     In 1998, the Legislature adopted a comprehensive plan to overhaul the
state's K-12 education capital finance system.  Under this plan, a substantial
commitment of state general fund revenues to the system has been made, totaling
approximately $360 million in FY 1999, with greater amounts likely in future
years.  There may be additional legislative activity during 1999 and beyond in
the areas of tax reform and school finance.  The combined impact of the
commitment of resources to K-12 education capital finance, continued tax
reduction, and the inability to increase revenues without a two-thirds of both
houses of the legislature, together with other actions and circumstances, may
result in deteriorating fiscal conditions in the future, which may adversely
affect state fund balances and fiscal health.

     Arizona has a diversified economic base that is not dependent on any single
industry. Principal economic sectors include services, manufacturing, mining,
tourism, and the military. Agriculture, which was at one time a major sector,
now plays a much smaller role in the State's economy.  For several decades, the
population of the State has grown at a substantially higher rate than the
population of the United States. While the State's economy flourished during the
early 80's, a substantial amount of overbuilding occurred, adversely affecting
Arizona-based financial institutions, many of which were placed under the
control of the Resolution Trust Corporation. Spillover effects produced further
weakening in the State's economy. The Arizona economy has begun to grow again,
albeit at a slower pace than experienced before the real estate collapse.  The
North American Free Trade Agreement is generally viewed as beneficial to the
State.  However, current and proposed reductions in federal military
expenditures may adversely affect the Arizona economy.

SPECIAL CONSIDERATIONS AFFECTING CALIFORNIA MUNICIPAL OBLIGATIONS

     Certain California constitutional amendments, legislative measures,
executive orders, civil actions and voter initiatives, as well as the general
financial condition of the state, could adversely affect the ability of issuers
of California municipal obligations to pay interest and principal on such
obligations.  The following information constitutes only a brief summary, does
not purport to be a complete description, and is based on information drawn from
official statements relating to securities offerings of the State of California
and various local agencies, available as of the date of this SAI.  While the
Company has not independently verified such information, it has no reason to
believe that such information is incorrect in any material respect.

     The California Economy and General Information.  From mid-1990 to late
     ----------------------------------------------
1993, the state suffered a recession with the worst economic, fiscal and budget
conditions since the 1930s. Construction, manufacturing (particularly related to
defense), exports and financial services, among others, were all severely
affected.  Job losses had been the worst of any post-war recession.
Unemployment reached 10.1% in January 1994, but fell sharply to 7.7% in October
and November 1994, reflecting the state's recovery from the recession.

                                       17
<PAGE>

     The recession seriously affected California tax revenues, which basically
mirror economic conditions.  It also caused increased expenditures for health
and welfare programs.  In addition, the state has been facing a structural
imbalance in its budget with the largest programs supported by the General Fund
(e.g., K-12 schools and community colleges--also known as "K-14 schools," health
and welfare, and corrections) growing at rates higher than the growth rates for
the principal revenue sources of the General Fund. As a result, the state
experienced recurring budget deficits in the late 1980s and early 1990s.  The
state's Controller reported that expenditures exceeded revenues for four of the
five fiscal years ending with 1991-92.  Moreover, California accumulated and
sustained a budget deficit in its Special Fund for Economic Uncertainties
("SFEU") approaching $2.8 billion at its peak at June 30, 1993.

     The accumulated budget deficits during the early 1990's, together with
expenditures for school funding which are not reflected in the state's budget,
and reduction of available internal borrowable funds, combined to significantly
deplete the state's cash resources to pay its ongoing expenses.  In order to
meet its cash needs, the state has had to rely for several years on a series of
external borrowings, including borrowings past the end of a fiscal year.  Such
borrowings are expected to continue in future fiscal years.  To meet its cash
flow needs in the 1995-96 fiscal year, California issued $2 billion of revenue
anticipation warrants which matured on June 28, 1996.  Because of the state's
deteriorating budget and cash situation, the rating agencies reduced the state's
credit ratings between October 1991 and July 1994.  Moody's Investors Service
lowered its rating from "Aa" to "A1," Standard & Poor's Ratings Group lowered
its rating from "AAA" to "A" and termed its outlook as "stable," and Fitch
Investors Service lowered its rating from "AA" to "A."

     However, since the start of 1994, California's economy has been recovering
steadily.  Employment has grew in excess of 500,000 during 1994 and 1995, and
400,000 additional jobs were created between the fourth quarter of 1996 and the
fourth quarter of 1997.  This trend is projected to continue through the rest of
the decade.  Unemployment, while remaining higher than the national average, has
come down from its 10% recession peak to under 6% in the Spring of 1998.
Because of the improving economy and California's fiscal austerity, the state
has had operating surpluses for the five consecutive fiscal years through 1996-
97.  Also, Standard & Poors upgraded its rating of California municipal
obligations back to "A+" on July 15, 1996 and the SFEU is projected to be $296
million on June 30, 1999.  However, the Asian economic difficulties since mid-
1997 are expected to have had a moderate dampening effect on California's
economy.  Any delay or reversal of the recovery may create new shortfalls in
revenues.

     Local Governments.  On December 6, 1994, Orange County, California became
     -----------------
the largest municipality in the United States to file for protection under the
Federal Bankruptcy laws.  The filing stemmed from approximately $1.7 billion in
losses suffered by the county's investment pool because of investments in high
risk "derivative" securities.  In September 1995, California's legislature
approved legislation permitting the county to use for bankruptcy recovery $820
million over 20 years in sales taxes previously earmarked for highways, transit,
and development.  In June 1996, the county completed an $880 million bond
offering secured by real property owned by the county.  In June 1996, the county
emerged from bankruptcy, and the county's investment rating by Standard & Poors
was "AAA" as of July 31, 1998.

                                       18
<PAGE>

     On January 17, 1994, an earthquake of the magnitude of an estimated 6.8 on
the Richter Scale struck Los Angeles County, California causing significant
damage to public and private structures and facilities.  While county residents
and businesses suffered losses totaling in the billions of dollars, the overall
effect of the earthquake on the county's and California's economy is not
expected to be serious.  However, Los Angeles County is experiencing financial
difficulty due in part to the severe operating deficits for the county's health
care system.  In August 1995, the credit rating of the county's long term bonds
was downgraded for the third time since 1992.  The county has received federal
and state assistance and the proposed fiscal 1999 budget for Los Angeles County
is the first in several years that does not begin with an operating deficit.
Even though the state has no existing obligations with respect to either Orange
County or Los Angeles County, the state may be required to intervene and provide
funding if the counties cannot maintain certain programs because of insufficient
resources.

     State Finances.  The monies of California are segregated into the General
     --------------
Fund and approximately 600 Special Funds.  The General Fund consists of the
revenues received by  the state's Treasury and not required by law to be
credited to any other fund, as well as earnings from state monies not allocable
to another fund.  The General Fund is the principal operating fund for the
majority of governmental activities and is the depository of most major revenue
sources of the state.  The General Fund may be expended as the result of
appropriation measures by California's Legislature and approved by the Governor,
as well as appropriations pursuant to various constitutional authorizations and
initiative statutes.

     The SFEU is funded with General Fund revenues and was established to
protect California from unforeseen revenue reductions and/or unanticipated
expenditure increases.  Amounts in the SFEU may be transferred by the state's
Controller to meet cash needs of the General Fund.  The Controller is required
to return monies so transferred without payment of interest as soon as there are
sufficient monies in the General Fund.  Any appropriation made from the SFEU is
deemed an appropriation from the General Fund, for budgeting and accounting
purposes.  For year-end reporting purposes, the Controller is required to add
the balance in the SFEU to the balance in the General Fund so as to show the
total monies then available for General Fund purposes.

     Inter-fund borrowing has been used for several years to meet temporary
imbalances of receipts and disbursements in the General Fund.  The 1998-99
Executive Budget projections submitted to the State Legislature in February
1998, forecast a 1999-00 General Fund budget gap of approximately $1.7 billion
and a 2000-01 gap of $3.7 billion.  As a result of changes made in the 1998-99
enacted budget, the 1999-00 gap is now expected to be roughly $1.3 billion, or
about $400 million less than previously projected, after application of reserves
created as part of the 1998-99 budget process.  Such reserves would not be
available against subsequent year imbalances.

     Changes in California Constitutional and Other Laws.  In 1978, California
     ---------------------------------------------------
voters approved an amendment to the California Constitution known as
"Proposition 13," which added Article XIIIA to the California Constitution.
Article XIIIA limits ad valorem taxes on real property and restricts the ability
of taxing authorities to increase real property taxes.  However, legislation
passed subsequent to Proposition 13 provided for the redistribution of
California's General Fund surplus to local agencies, the reallocation of
revenues to local agencies and the

                                       19
<PAGE>

assumption of certain local obligations by the state so as to assist California
municipal issuers to raise revenue to pay their bond obligations. It is unknown
whether additional revenue redistribution legislation will be enacted in the
future and whether, if enacted, such legislation will provide sufficient revenue
for such California issuers to pay their obligations. California is also subject
to another Constitutional Amendment, Article XIIIB, which may have an adverse
impact on California state and municipal issuers. Article XIIIB restricts the
state from spending certain appropriations in excess of an appropriation's limit
imposed for each state and local government entity. If revenues exceed such
appropriation's limit, such revenues must be returned either as revisions in the
tax rates or fee schedules.

     In 1988, California voters approved "Proposition 98," which amended Article
XIIIB and Article XVI of the state's Constitution. Proposition 98 (as modified
by "Proposition 111," which was enacted in 1990), changed state funding of
public education below the university level and the operation of the state's
appropriations limit, primarily by guaranteeing K-14 schools a minimum share of
General Fund revenues.  In 1986, California voters approved "Proposition 62,"
which provided in part that any tax for general governmental purposes imposed by
a local government be approved by a two-thirds vote of the governmental entity's
legislative body and by a majority of its electorate and that any special tax
imposed by a local government be approved by a two-thirds vote of the
electorate.  In September 1995, the California Supreme Court upheld the
constitutionality of Proposition 62, creating uncertainty as to the legality of
certain local taxes enacted by nonchartered cities in California without voter
approval.

     In 1996, California voters approved "Proposition 218," which added Articles
XIIIC and XIIID to the state's Constitution generally requiring voter approval
of most tax or fee increases by local governments and curtailing local
government use of benefit assessments to fund certain property-related services
to finance infrastructure.  Proposition 218 also limits the use of special
assessments or "property-related" fees to services or infrastructure that confer
a "special benefit" to specific property; police, fire and other services are
now deemed to benefit the public at large and, therefore, could not be funded by
special assessments.  Finally, the amendments enable the voters to use their
initiative power to repeal previously-authorized taxes, assessments, fees and
charges.  The interpretation and application of  Proposition 218  will
ultimately be determined by the courts.  Proposition 218  is generally viewed as
restricting the fiscal flexibility of local governments, and for this reason,
some ratings of California cities and counties have been, and others may be,
reduced.

     The Governor in the 1998-99 budget bill proposed that California reduce its
Vehicle License Fee (a personal property tax on the value of automobiles, the
"VLF") by 75% over five years, by which time the tax cut would be more than $3.5
billion annually.  Under current law, the VLF is entirely dedicated to city and
county government, and the Governor proposed to use the General Fund to offer
the loss of VLF funds to local government.  The bill as passed provides for a
phased-in reduction of the VLF and provides that the General Fund be used to
replace the lost revenues to local governments.  On January 1, 1999, the VLF
will be reduced by 25%, at a cost to the General Fund of approximately $500
million in the 1998-99 Fiscal Year and about $1 billion annually thereafter.

     In addition to the reduction of the VLF, the 1998-99 budget bill included
increases in the personal income tax dependent credit (resulting in a $612
million General Fund cost in 1998-99), a

                                       20
<PAGE>

nonrefundable renters tax credit (resulting in a $133 million cost in 1998-99),
and various targeted business tax credits (monthly in a $106 million cost in
1998-99). It remains to be seen, as such, what impact these changes in
California laws, fee and tax policies will have on existing and future
California security obligations.

     Other Information.  Certain debt obligations held by the Funds may be
     -----------------
obligations payable solely from lease payments on real or personal property
leased to the state, cities, counties or their various public entities.
California law provides that a lessor may not be required to make payments
during any period that it is denied use and occupancy of the property in
proportion to such loss.  Moreover, the lessor only agrees to appropriate
funding for lease payments in its annual budget for each fiscal year.  In case
of a default under the lease, the only remedy available against the lessor is
that of reletting the property; no acceleration of lease payments is permitted.
Each of these factors presents a risk that the lease financing obligations held
by the Fund would not be paid in a timely manner.

     Certain debt obligations held by the Funds may be obligations payable
solely from the revenues of health care institutions.  The method of
reimbursement for indigent care, California's selective contracting with health
care providers for such care and selective contracting by health insurers for
care of its beneficiaries now in effect under California and federal law may
adversely affect these revenues and, consequently, payment on those debt
obligations.

     There can be no assurance that general economic difficulties or the
financial circumstances of California or its towns and cities or its trading
partners in Asia, where California exports $50 billion in goods representing
nearly half of $105 billion in total exports, will not adversely affect the
market value of California municipal securities or the ability of obligors to
continue to make payments on such securities.

         SPECIAL CONSIDERATIONS AFFECTING OREGON MUNICIPAL OBLIGATIONS

     The concentration of the Oregon Tax-Free Fund in securities issued by
governmental units of only one state exposes the Fund to risks greater than
those of a more diversified portfolio holding securities issued by governmental
units of different states and different regions of the country.

     State Bonds and Revenues.  As of September 1, 1998, $2.90 billion (rounded)
     ------------------------
in general obligation bonds issued by the State of Oregon and its agencies were
outstanding, including $135.8 million (rounded) in general obligation bonds
supported by the budget for the State's general fund and $2.76 billion (rounded)
of self-supporting general obligation bonds. The State's self-supporting general
obligation bonds include $2.05 billion (rounded) of State veteran's bonds,
which, in the event of poor economic conditions resulting in an increased number
of mortgage defaults, could cease to be self-supporting. All of the existing and
outstanding general obligation bonds of the State have been issued under
specific State constitutional provisions that authorize the issuance of such
bonds and provide authority for ad valorem taxation to pay the principal of and
interest on such bonds. With the exception of the veteran's bonds, for which no
more than two mills on each dollar valuation may be levied to pay principal and
interest, the authority of the State to tax property for the payment of its
general obligation bonds is unlimited. Since at least 1950, the

                                       21
<PAGE>

State has not imposed ad valorem tax for the payment of any of its obligations
because other revenues, including those generated by the self-supporting bonds,
have been sufficient.

     In addition to general obligation bonds, various State statutes authorize
the issuance of State revenue bonds and certificates of participation. These
limited obligations of the State or its agencies or instrumentalities may be
payable from a specific project or source, including lease rentals. The State is
not authorized to impose ad valorem taxes on property for the payment of
principal and interest on these bonds, so they are more sensitive to changes in
the economy. There can be no assurance that future economic problems will not
adversely affect the market value of Oregon obligations held by the Fund or the
ability of the respective obligors (both private and governmental) to make
required payments on such obligations.

     Oregon does not have a sales tax. As a result, State tax revenues are
particularly sensitive to economic recessions. The principal sources of State
tax revenues are personal income and corporate income taxes. In the
legislatively adopted budget for the 1997-99 biennium, approximately 97.0% of
the State's revenues for the 1997-99 biennium were projected to come from
combined income taxes, insurance taxes, gift and inheritance taxes, and
cigarette and tobacco taxes. Since 1983 State revenues have improved
substantially, and in recent years the State has granted tax refunds because of
budget surpluses, as required by statute.

     Oregon Economic and Revenue Forecast.  A quarterly Economic and Revenue
     ------------------------------------
Forecast is prepared by the State Department of Administrative Services as
required by ORS 291.342.  A complete copy of the State's most recent quarterly
Economic and Revenue Forecast is posted at the Oregon Department of
Administrative Services' web site:  www.oea.das.state.or.us when publicly
released.  The following is a portion of the summary of the September 1, 1998
Oregon Economic and Revenue Forecast prepared by the State of Oregon for use in
its Official Statements for State Obligations issued between October 1, 1998 and
January 1, 1999 (a delay of approximately 30 days typically following public
release of the most recent quarterly Oregon Economic and Revenue Forecast and
the preparation of this summary material for inclusion in State Official
Statements).

     Economic Forecast.  Oregon's economy is clearly slowing.  Asia's weakness
     -----------------
is dampering the state's high technology, forest products and agriculture
sectors.  Oregon's close ties to Asian export markets is causing the state to
feel the impact o the region's financial crisis proportionately more than the
country as a whole.  However, similar to the nation, Oregon consumers appear to
be proving the fuel to keep the state's economic expansion going.

     Oregon's economy has been at the forefront in absorbing the impact of
Asia's recessions.  The Office of Economic Analysis (OEA) expects this trend to
continue.  Following years of superior economic performance, the state's growth
rate is expected to hover near the national average over the next two years.
The state's mid-1990's economic boom is clearly over.  Nonetheless, Oregon's
economy is likely to continue growing as long as the nation avoids a recession.

     Oregon's job and income growth rates are expected to be close to the
national average.  This contrasts with the state's much stronger growth
throughout the 1990's.  On a per capita basis, Oregon personal income is
expected to slip relative to the national average in both 1998

                                       22
<PAGE>

and 1999. This has not happened since 1992. Average wages are also expected to
grow more slowly than the U.S. as a whole in 1998 and 1999.

     OEA projects a similar trend for job growth in the state.  Non-farm payroll
employment increased 3.4 percent in 1997.  It is projected to rise 2.6 percent
for 1998 and 1.4 percent for 1999.

     Oregon's economic boom in the mid-1990's can be largely traced to rapid
expansion of the high technology sector.  A surge in semiconductor investment
triggered rapid growth in construction and electronics industry employment.
Modest employment declines are anticipated for both electronics and construction
over the next four quarters.  The downturn in these two sectors is the catalyst
for slower economic growth in the state.

     The major risk to Oregon's economy is worsening of the Asian economic
crisis.  If the recessions now underway in Asia turn out to be more severe than
currently-expected.  Oregon's economy will slow further.  Japan is the state's
largest export market.  A severe recession in Japan, rather than the moderate
one now anticipated, would have a significant impact on Oregon exporters.

     Demographic Forecast.  The Office of Economic Analysis projects total
     --------------------
population in Oregon to grow from 3.217 million in 1997 to 3.597 million in
2005, an increase of 11.8 percent.  This reflects a continuation of moderate
population growth for the state.  The fastest growth will occur in the young
adult population (18-24 year-olds), older wage earners (ages 45-64 years-old),
and those ages 85 and older.

     Revenue Forecast.  The Office of Economic Analysis now projects General
     ----------------
Fund revenue of $8,356.7 million for the 1997-99 biennium.  This is a decrease
of $216.5 million from the June forecast.  The September forecast is $131.6
million higher than the 1997 close of legislative session ("COS") forecast.

     The Oregon Supreme Court ruled that the state has illegally taxed Federal
government pension income since 1991.  The September forecast includes a $306.1
million reduction to account for refunds of back taxes and lower future tax
collections from pension income.

     The reduction in revenue caused by the pension income decision is partly
offset by higher collections in the second quarter and a higher forecast for
capital gains income.  Personal income tax collections in the second quarter
exceeded the June estimate by $63.7 million.  This is attributed to a jump in
capital gains income during the 1997 tax year.

     The surge in capital gains income explains why Oregon's personal income tax
revenue continues to rise rapidly despite the slowing state economy.

     Oregon's corporate income tax revenue has clearly been affected by the
softening state economy.  Second quarter corporate income tax revenue came in
$18.3 million below the June forecast.  The slower pace of collections and a
lower national profit forecast from DRI are the major reasons for the $28.3
million reduction in the 1997-99 corporate income tax forecast.

                                       23
<PAGE>

     All non-corporate income tax revenue is now projected to exceed the COS
forecast by $167.9 million.  This is 2.2 percent above the close of session
forecast.  This means that a surplus kicker refund for individuals is projected
for the 1999-2001 biennium.

     A surplus kicker credit is not anticipated for corporations.  The corporate
income tax forecast is $36.3 million below the COS projection.

     1999-2001 General Fund Revenue.  General Fund revenue is projected to total
     ------------------------------
$9,908.0 million for the 1999-2001 biennium.  The 1999-2001 beginning balance is
estimated to be $327.0 million.  This leaves a General Fund resource projection
of $10,235 million.

     The General Fund revenue projection is $30.3 million higher than the June
forecast.  However, the beginning balance estimate is $208.7 million less than
expected in June.  This leaves the September General Fund resources forecast
$178.4 million below the previous projection.

     Recent Environmental Developments.  In 1991 and 1992, in response to
     ---------------------------------
concerns over diminishing salmon runs, three populations of Snake River salmon
were placed on the Endangered Species list. More recently, the National Marine
Fisheries Service and the U.S. Fish and Wildlife Service have commenced status
reviews of hundreds of additional salmon and trout populations in the Columbia
Basin and throughout Western Oregon. The Snake River salmon listings have
already had substantial economic impacts, primarily through increased
electricity rates and related impacts on rate-sensitive industries such as the
aluminum industry. Efforts to protect salmon and steelhead populations may
eventually affect a wide variety of industrial, recreational and land use
activities, with corresponding impacts on long-term economic growth; however,
the magnitude and extent of any future environmental action is impossible to
predict at this time. The State's economic forecasts do not address the
potential impact of endangered species problems on Oregon's economy.

     Recent Developments Affecting Government Revenues.  Ballot Measure 5.
     -------------------------------------------------
Article XI, section 11b of the Oregon Constitution, adopted by Oregon's voters
in November 1990 ("Ballot Measure 5"), imposes an aggregate limit on the rate of
property taxes, including ad valorem taxes, that may be levied against any real
or personal property. The limit is subject to certain exceptions and is being
phased in over a five-year period. Beginning with the tax year that starts on
July 1, 1996, the final year of the phase-in period, not more than $15 per
$1,000 of real market value can be levied against any piece of property. Of this
amount, $5 may be used for public education, and the remaining $10 may be used
for general governmental purposes.

     The limitations of Ballot Measure 5 do not apply to taxes imposed to pay
the principal of and interest on bonded indebtedness authorized by a specific
provision of the State Constitution. Therefore, the ability of the State to levy
taxes to service its constitutionally authorized general obligation bonds is not
subject to the limit. In addition, because the State currently receives its
revenues from sources other than property taxes, Ballot Measure 5 has not
directly affected State revenues.

                                       24
<PAGE>

     The tax limitations of Ballot Measure 5 do not apply to user fees,
licenses, excise or income taxes and incurred charges for local improvements.
Since 1990 local governments have begun to rely more heavily on such fees and
taxes to finance certain services and improvements.

     Ballot Measure 5 has controlled the growth of local property tax revenues
since its adoption.  Although the growth in local property valuations during the
period 1991 to 1997 has somewhat mitigated the potential impacts of Ballot
Measure 5, revenues of local government units in Oregon have generally been
adversely affected by the adoption of Ballot Measure 5.  This appears to be
particularly true with respect to school district operating revenues.

     Ballot Measure 5 required the State to replace a substantial portion of the
lost revenues of local school districts through the end of fiscal year 1995-96.
Although this obligation has now expired, the extent of revenue loss perceived
to have been incurred by local school districts indicates that the State may
continue to provide significant revenue relief to these governmental units.  In
addition, the provisions of the initiative known as Ballot Measure 50, as
defined and discussed below, is expected to also result in the State making
further financial assistance available to certain units of local government as a
result of further restrictions and limitations placed upon the ability of units
of local government to generate revenues through Oregon's system of ad valorem
property taxation.

     Ballot Measure 50.  The 1997 Legislative Assembly referred to Oregon
     -----------------
voters, and the voters approved at the May 20, 1997, special election, a
constitutional amendment ("Measure 50") that replaced the property tax
limitations imposed by a voter initiative approved at the November 5, 1996,
general election ("Measure 47").  Measure 50 repealed Measure 47 and replaced it
with new ad valorem property tax limitations similar to those which would have
been required to be enacted under Measure 47.  Measure 50 limits the assessed
value for the tax year 1997-98 to its 1995-96 "real market value," less ten
percent.  In implementing Measure 50, the Oregon Legislature also ordered a 17%
reduction in 1997-98 in operating tax levies (which amounts vary by government
entity).  Thereafter, Measure 50 limits the valuation growth of property
assessments on each unit of property to three percent per year for future tax
years.  Measure 50 preserves the general limitations on property tax rates of $5
per $1,000 for public education and $10 per $1,000 for all other governmental
services.  Measure 50 also requires that any new property taxes be approved by a
majority of the voters in an election where at least 50% of eligible voters
participate, except in the instance of a general election in even numbered
years.  In addition, Measure 50 requires voter approval of the use of fees,
taxes, assessments or other charges as alternative funding sources to make up
for revenue reductions caused by the amended property tax limits.

     Units of local government that levy and collect property taxes are most
directly affected by Measure 50.  The State does not levy or collect property
taxes, but relies instead on state income taxes as the main source of revenue
for the State's general fund.  Therefore, Measure 50's main impact on the State
will likely be to increase pressure on the Legislative Assembly to use State
funds to replace revenues lost by local governments.  Measure 50 requires the
Legislative Assembly to replace the estimated $428 million in revenues that the
public school system, including community colleges, is expected to lose in the
1997-99 biennium because of the property tax limitation.  In this manner,
Measure 50 may influence the State budgeting process.

                                       25
<PAGE>

     The Oregon Legislative Revenue Office has estimated that the total
reduction in property tax revenues collected by local governments under Measure
50 will be approximately $389 million for the tax year 1997-98 and approximately
$454 million for the tax year 1998-99.  The first year of implementation
occurred with the local property tax bills subject to Measure 50 being
distributed in late November 1997.  Until local governments and county tax
assessors and collectors have significantly more practical experience with
implementing and administering the property tax system under the guidelines and
limitations of Measure 50 and its implementing legislation, the actual short
term and long term financial effects of Measure 50 on local governments will be
uncertain.

     The Initiative Process. The Oregon Constitution reserves to the people of
     ----------------------
the State initiative and referendum power pursuant to which measures designed to
amend the State Constitution or enact legislation, can be placed on the
statewide general election ballot for consideration by the voters. "Referendum"
generally means measures referred to the electors by a legislative body such as
the State Legislative Assembly or the governing body of a city, county or other
political subdivision, while "initiative" generally means a measure placed
before the voters as a result of a petition circulated by one or more private
citizens.

     Any person may file a proposed initiative with the Oregon Secretary of
State's office. The Oregon Attorney General is required by law to draft a
proposed ballot title for the initiative, and interested parties may submit
comments on the legal sufficiency of the proposed ballot title and on whether
the proposed initiative complies with a "one subject only" rule for initiative
measures. After considering any public comments, the Attorney General must
either certify or revise the draft ballot title. In general, any elector who
timely submitted written comments on the draft ballot title may petition the
Oregon Supreme Court seeking a revision of the certified ballot title.

     To have an initiative placed on a general election ballot, the proponents
of the proposed initiative must submit to the Secretary of State initiative
petitions signed by the number of qualified voters equal to a specified
percentage of the total number of votes cast for all candidates for governor in
the most recent gubernatorial election. The initiative petition must be filed
with the Secretary of State not less than four months prior to the general
election at which the proposed measure is to be voted upon.  State law permits
persons circulating initiative petition to pay money to persons obtaining
signatures for the petition.

     Over the past decade Oregon has witnessed increasing activity in the number
of initiative petitions that have qualified for the statewide general election.
As of July 20, 1998, several initiatives had qualified to be placed on the
November 1998 general election ballot.  One of these, an initiative restricting
forest harvest practices, is forecast to potentially result in a decrease in
State revenues from timber harvest tax collections of approximately $30 million
per year if enacted.  In recent years, a number of initiatives involving the
fiscal operations of the State were proposed and placed on the ballot. Several
of these initiatives have been approved by the voters and have had or will have
a significant impact on the fiscal operations of the State and local
governments. See "Recent Developments Affecting Government Revenues - Ballot
Measure 5 and Measure 50." Other initiatives, had they been approved by the
voters, also may have had significant impacts on the fiscal operations of the
State.

                                       26
<PAGE>

     It is difficult to predict with certainty either the likelihood of a
proposed initiative measure obtaining the required number of valid initiative
petition signatures or the likelihood of an initiative that has acquired the
necessary number of valid signatures being approved by the voters. There can be
no assurance that additional initiatives that will have a material adverse
impact on the financial condition of the State or units of local government or
the State's or units of local government's ability to collect the revenues
required to repay their general obligation bonds, revenue bonds or other
obligations will not be proposed, placed on the ballot, or be approved by the
voters.

     Judicial challenges seeking interpretations and clarifications of the scope
and application of Ballot Measure 5 continue to be filed.  It is anticipated
that the passage of Measure 50 will also require substantial judicial
interpretation of its meaning and application.  If it is judicially determined
that certain statutes adopted by the Oregon legislature to implement Ballot
Measure 5 or statutes adopted relating to Measure 50 do not adequately implement
the restrictions contained in that measure, local governments may have to seek
new funding sources for certain items which have been traditionally financed in
part through the issuance of voter approved ad valorem tax supported
indebtedness.

     The Oregon Bond Market.  There is a relatively small active market for
     ----------------------
municipal bonds of Oregon issuers other than the general obligations of the
State itself, and the market price of such other bonds may therefore be
volatile.  If the Oregon Tax-Free Fund were forced to sell a large volume of
Oregon Obligations owned by it or for any reason, such as to meet redemption
requests for a large number of its shares, there is a risk that the large sale
itself would adversely affect the value of the Oregon Tax-Free Fund's portfolio.

SPECIAL CONSIDERATIONS AFFECTING COLORADO MUNICIPAL OBLIGATIONS

     Among the most significant sectors of the State's economy are services,
trade, manufacture of durable and non-durable goods and tourism.  Between late
1984 and mid-1987, the State's economy was adversely affected by numerous
factors, including the contraction of the energy sector, layoffs by advanced
technology firms and an excess supply of both residential and nonresidential
buildings causing employment in the construction sector decline.  As a result of
these conditions, certain areas of the State experienced particularly high
unemployment.  Furthermore, in 1986, for the first time in 32 years, job
generation in the State was negative and, in 1986, for the first time in 21
years, the State experienced negative migration, with more people leaving the
State than moving in.

     From 1987 through 1996, there has been moderate but steady improvement in
the Colorado economy:  per-capita income increased approximately 54.9% (4.5% in
1996) and retail trade sales increased approximately 81.9% (6.9% in 1996).  The
State's estimated growth rate is above the national growth rate and the State's
unemployment rate is still below the national unemployment rate (in 1996 the
State's unemployment rate was 5.4%).

     The State of Colorado's political subdivisions include approximately 1,600
units of local government in Colorado, including counties, statutory cities and
towns, home-rule cities and counties, school districts and a variety of water,
irrigation, and other special districts and special improvement districts, all
with various constitutional and statutory authority to levy taxes and incur
indebtedness.

                                       27
<PAGE>

     The State derives all of its General Fund revenues from taxes.  The two
most important sources of these revenues are sales and use taxes and personal
income taxes, which accounted for approximately 31.5% and 53.2%, respectively,
of total General Fund revenues during fiscal year 1995 and approximately 31.0%
and 54.3%, respectively, of total General Fund balance for fiscal year 1995 was
$488.5 million and for fiscal year 1996 was approximately $368.5 million.

     The Colorado Constitution contains strict limitations on the ability of the
State to create debt except under certain very limited circumstances.  However,
the constitutional provision has been interpreted not to limit the ability of
the State to issue certain obligations which do not constitute debt, including
short-term obligations which do not extend beyond the fiscal year in which they
are incurred and lease purchase obligations which are subject to annual
appropriation.  The State is authorized pursuant to State statutes to issue
short-term notices to alleviate temporary cash flow shortfalls.  The most recent
issue of such notes, issued on July 1, 1997, was given the highest rating
available for short-term obligations by S&P (SP-1+) and Fitch (F-1+) (A rating
on such notes was not requested from, and consequently no rating was given by,
Moody's).  Because of the short-term nature of such notes, their ratings should
not be considered necessarily indicative of the State's general financial
condition.

     On November 3, 1992, the Colorado voters approved a State constitutional
amendment (the "Amendment") that restricts the ability of the Sate and local
governments to increase taxes, revenues, debt and spending.  The Amendment
provides that its provisions supersede conflicting State constitutional, State
statutory, charter or other State or local provisions.

     Among other provisions, the Amendment requires the establishment of
emergency reserves, limits increases in district revenues and limits increases
in district fiscal year spending.  As a general matter, annual State fiscal year
spending may change not more than inflation plus the percentage change in State
population in the prior calendar year.  Annual local district fiscal year
spending may change no more than inflation in the prior calendar year plus
annual local growth, as defined in and subject to the adjustments provided in
the Amendment.  The Amendment provides that annual district property tax
revenues may change no more than inflation in the prior calendar year plus
annual local growth, as defined in and subject to the adjustments provided in
the Amendment.  District revenues in excess of the limits prescribed by the
Amendment are required, absent voter approval, to be refunded by any reasonable
method, including temporary tax credits or rate reductions.  The State
anticipates that revenues in excess of the limits applicable for the 1996 fiscal
year will be refunded to certain taxpayers in the State in accordance with the
Amendment.  In addition, the Amendment prohibits new or increased real property
transfer taxes, new State real property taxes and new local district income
taxes.  The Amendment also provides that a local district may reduce or end its
subsidy to any program (other than public education through grade 12 or as
required by federal law) delegated to it by the State General Assembly for
administration.

     This description is not intended to constitute a complete description of
all of the provisions of the Amendment.  Furthermore, many provisions of the
Amendment and their application are unclear.  Several statutes have been enacted
since the passage of the Amendment attempting to clarify the application of the
Amendment with respect to certain governmental entities and activities and
numerous court decisions have been rendered interpreting certain of the
Amendment's provisions.  However, many provisions of the Amendment may require
further legislative or judicial clarification.  The future impact of the
Amendment on the financial

                                       28
<PAGE>

operations and obligations of the State and local governments in the State
cannot be determined at this time. Attempts to apply the provisions of the
Amendment to obligations issued prior to the approval of the Amendment may be
challenged as violation of protections afforded by the federal constitution
against impairment of contracts.

       SPECIAL CONSIDERATIONS AFFECTING MINNESOTA MUNICIPAL OBLIGATIONS

     Diversity and a significant natural resource base are two important
characteristics of the State's economy.

     When viewed in 1994 on an aggregate level, the structure of the State's
economy parallels the structure of the United States economy as a whole.  State
employment in 10 major sectors was distributed in approximately the same
proportions as national employment.  In all sectors, the share of total State
employment was within 2.5 percentage points of national employment share.

     Some unique characteristics of the State's economy are apparent in
employment concentrations in many major industries.  The State's high technology
industries accounted for more than 7% of all employment in the State of 1994,
and the State's concentration of high technology employment is 50% higher than
the United States average.  This emphasis is partly explained by the location in
the State of Honeywell, IBM, 3M Company, Unisys and Seagate Technology.

     The importance of the State's resource base for overall employment is
apparent in the employment mix in non-durable goods industries.  The State's
concentration of employment in 1994 was 50% higher than the United States
average in the food and kindred products industry and almost 50% higher in the
forest and forestry products industry.  Both of these rely heavily on renewable
resources in the State.  Over half of the State's acreage is devoted to
agricultural purposes, and nearly one-third to forestry.

     The printing and publishing industry and medical products manufacturing
industry are also relatively more important in the State than in the United
States.  From 1985 to 1984, employment in the State's printing and publishing
industry grew 28.2%, compared to the United States growth rate of 7.8% over the
same period.  Printing and publishing companies provided 2.9% of all the State's
private industry jobs in 1994.  In the medical products manufacturing industry,
the State's concentration of employment in 1994 was the second highest in the
nation and twice the United States average.

     Mining is currently a less significant factor in the State economy than it
once was.  Mining employment, primarily in the iron ore or taconite industry,
dropped from 17.3 thousand in 1979 to 7.4 thousand in 1994.  It is not expected
that mining employment will return to 1979 levels.  However, Minnesota retains
significant quantities of taconite as well as copper, nickel, cobalt, and peat
which may be utilized in the future.

     In the period 1985 to 1994, employment in non-farm industries increased
24.1%, compared to an increase of 16.9% in the United States.  Manufacturing has
been a strong sector, with Minnesota employment outperforming its United States
counterpart in the period from 1985 to 1994 with an increase of 10.5% compared
to a decrease of 4.9% in the United States in the same

                                       29
<PAGE>

period. Over 40% of the total increase in Minnesota non-farm employment between
the years 1984-1994 resulted from 45.5% increase in employees in the services
industry during this period. Mining was the only industry where employment
decreased between 1984-1995 in both Minnesota and the United States, dropping by
9.4% in Minnesota and 34.8% in the United States

     Since 1980, State per capita personal income has been within three
percentage points of national per capita personal income.  The State's per
capital income, which is computed by dividing personal income by total resident
population, has generally remained above the national average in spite of the
early 1980's recessions and some difficult years in agriculture.  In 1994,
Minnesota per capita personal income was 102.6% of its U.S. counterpart.

     In the level of personal income per capita, Minnesota ranked second among
twelve north central states in both 1992 and 1994.  During the period 1985 to
1994, Minnesota ranked second among such states in annual average growth of
personal income and fifth during the period 1993 to 1994.  Minnesota ranked
twentieth nationally and third among the twelve north central states with a per
capita disposable income of $18,792 in 1994.  During 1990-1992, wage and salary
disbursements which constitute some 60% of total personal income grew 12.3% in
Minnesota as compared to 8.3% for the United States.  personal income in
Minnesota grew more rapidly than seven other north central states' averages
during 1993-1994, and faster than the United States average.  From 1985 to 1994,
Minnesota non-agricultural employment grew 24.1% while such employment in the
United States grew 16.9%.

     Each of the Trustees and Officers listed above, act in the identical
capacities for Wells Fargo Variable Trust and Wells Fargo Core Trust
(collectively the "Fund Complex").  Trustees are compensated annually by the
Trust and by all the registrants in each fund complex they serve beginning
September 17, 1999, and beginning March 26, 1999, receive a per-meeting fee of
$250.  Trustees also are reimbursed for all out-of-pocket expenses relating to
attendance at board meetings.  Each of the Trustees and Officers of the Trust
serves in the identical capacity as trustees and/or officers of each registered
open-end management investment company in the Fund Complex.  The Trustees are
compensated by other companies and trusts within a fund complex for their
services as directors/trustees to such companies and trusts.  Currently the
Trustees do not receive any retirement benefits or deferred compensation from
the Trust or any other member of each fund complex.

     As of the date of this SAI, Trustees and Officers of the Trust as a group
beneficially owned less than 1% of the outstanding shares of the Trust.

     Investment Advisor.  Wells Fargo Bank provides investment advisory services
     ------------------
to the Funds.  As investment advisor, Wells Fargo Bank furnishes investment
guidance and policy direction in connection with the daily portfolio management
of the Funds. Wells Fargo Bank furnishes to the Trust's Board of Trustees
periodic reports on the investment strategy and performance of each Fund.  Wells
Fargo Bank provides the Funds with, among other things, money market security
and fixed-income research, analysis and statistical and economic data and
information concerning interest rate and securities markets trends, portfolio
composition, and credit conditions.

     As compensation for its advisory services, Well Fargo Bank is entitled to
receive a monthly fee at the annual rates indicated below of each Fund's average
daily net assets:

                                                           Annual Rate

- ----                                              -----------------------------
Arizona Tax-Free Fund                                          0.40%

National Limited Term Tax-Free Fund                            0.40%

     General.  Each Fund's Advisory Contract will continue in effect for more
     -------
than two years from the effective date provided the continuance is approved
annually (i) by the holders of a majority of the respective Fund's outstanding
voting securities or by the Trust's Board of Trustees and (ii) by a majority of
the Trustees of the Trust who are not parties to the Advisory Contract or
"interested persons" (as defined in the 1940 Act) of any such party.  A Fund's
Advisory Contract may be terminated on 60 days' written notice by either party
and will terminate automatically if assigned.

     Investment Sub-Advisors.  Wells Fargo Bank has engaged Wells Capital
     -----------------------
Management ("WCM") to serve as Investment Sub-Advisor to the Short-Intermediate
U.S. Government Income Fund.  Subject to the direction of the Trust's Board of
Trustees and the overall supervision and control of Wells Fargo Bank and the
Trust, WCM makes recommendations regarding the investment and reinvestment of
the Funds' assets.  WCM furnishes to Wells Fargo Bank periodic reports on the
investment activity and performance of the Funds.  WCM also furnishes such
additional reports and information as Wells Fargo Bank and the Trust's Board of
Trustees and officers may reasonably request.

     As compensation for its sub-advisory services, WCM is entitled to receive a
monthly fee equal to an annual rate of 0.15% of the first $400 million of the
Funds' average daily net assets, 0.125% of the next $400 million of the Funds'
net assets, and 0.10% of net assets over

                                       33
<PAGE>

$800 million. WCM receives a minimum annual sub-advisory fee of $120,000 from
each Fund. This minimum annual fee payable to WCM does not increase the advisory
fee paid by each Fund to Wells Fargo Bank. These fees may be paid by Wells Fargo
Bank or directly by the Fund. If the sub-advisory fee is paid directly by the
Fund, the compensation paid to Wells Fargo Bank for advisory fees will be
reduced accordingly.

     Portfolio Managers.
     ------------------

[to be inserted]



     Administrator.  The Trust has retained Wells Fargo Bank as Administrator on
     -------------
behalf of each Fund.  Under the Administration Agreement between Wells Fargo
Bank and the Trust, Wells Fargo Bank shall provide as administration services,
among other things:  (i) general supervision of the Funds' operations, including
coordination of the services performed by each Fund's investment Advisor,
transfer agent, custodian, shareholder servicing agent(s), independent auditors
and legal counsel, regulatory compliance, including the compilation of
information for documents such as reports to, and filings with, the U.S.
Securities and Exchange Commission ("SEC") and state securities commissions; and
preparation of proxy statements and shareholder reports for each Fund; and (ii)
general supervision relative to the compilation of data required for the
preparation of periodic reports distributed to the Trust's officers and Board of
Trustees.  Wells Fargo Bank also furnish office space and certain facilities
required for conducting the Funds' business together with ordinary clerical and
bookkeeping services.  The Administrator is entitled to receive a fee of 0.15%
of average daily net assets on an annual basis.

     Distributor.  Stephens (the "Distributor"), located at 111 Center Street,
     -----------
Little Rock, Arkansas  72201, serves as the Distributor for the Funds.  Each
Fund has adopted a distribution plan (a "Plan") under Section 12(b) of the 1940
Act and Rule 12b-1 thereunder (the "Rule") for its Class B and Class C shares.
The Plan was adopted by the Trust's Board of Trustees, including a majority of
the Trustees who were not "interested persons" (as defined in the 1940 Act) of
the Funds and who had no direct or indirect financial interest in the operation
of the Plan or in any agreement related to the Plan (the "Non-Interested
Trustees").

     Under the Plan and pursuant to the related Distribution Agreement, the
Funds may pay Stephens up to 0.75% of the average daily net assets attributable
to the Class B and Class C shares of the Funds as compensation for distribution-
related services or as reimbursement for distribution-related expenses.

     The actual fee payable to the Distributor is determined, within such
limits, from time to time by mutual agreement between the Trust and the
Distributor and will not exceed the maximum sales charges payable by mutual
funds sold by members of the National Association of Securities Dealers, Inc.
("NASD") under the Conduct Rules of the NASD.  The Distributor may enter into
selling agreements with one or more selling agents (which may include Wells
Fargo Bank and its affiliates) under which such agents may receive compensation
for

                                       34
<PAGE>

distribution-related services from the Distributor, including, but not limited
to, commissions or other payments to such agents based on the average daily net
assets of Fund shares attributable to their customers. The Distributor may
retain any portion of the total distribution fee payable thereunder to
compensate it for distribution-related services provided by it or to reimburse
it for other distribution-related expenses.

     General.  The Plan will continue in effect from year to year if such
     -------
continuance is approved by a majority vote of both the Trustees of the Trust and
the Non-Interested Trustees.  Any Distribution Agreement related to the Plan
also must be approved by such vote of the Trustees and the Non-Interested
Trustees.  Such Agreement will terminate automatically if assigned, and may be
terminated at any time, without payment of any penalty, by a vote of a majority
of the outstanding voting securities of the relevant class of the Fund or by
vote of a majority of the Non-Interested Trustees on not more than 60 days'
written notice.  The Plan may not be amended to increase materially the amounts
payable thereunder without the approval of a majority of the outstanding voting
securities of the Fund, and no material amendment to the Plan may be made except
by a majority of both the Trustees of the Trust and the Non-Interested Trustees.

     The Plan requires that the Treasurer of the Trust shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Plan.  The Rule also
requires that the selection and nomination of Trustees who are not "interested
persons" of the Trust be made by such disinterested Trustees.

     Wells Fargo Bank, an interested person (as that term is defined in Section
2(a)(19) of the 1940 Act) of the Trust, acts as a selling agent for the Funds'
shares pursuant to selling agreements with Stephens authorized under the Plan.
As a selling agent, Wells Fargo Bank has an indirect financial interest in the
operation of the Plans.  The Board of Trustees has concluded that the Plan is
reasonably likely to benefit the Funds and their shareholders because the Plan
authorize the relationships with selling agents, including Wells Fargo Bank,
that have previously developed distribution channels and relationships with the
retail customers that the Funds are designed to serve.  These relationships and
distribution channels are believed by the Board to provide potential for
increased Fund assets and ultimately corresponding economic efficiencies (i.e.,
lower per-share transaction costs and fixed expenses) that are generated by
increased assets under management.

     Shareholder Servicing Agent.  The Funds have approved a Servicing Plan for
     ---------------------------
each Fund and have entered into related  shareholder servicing agreements with
financial institutions, including Wells Fargo Bank.  Under the agreements,
Shareholder Servicing Agents (including Wells Fargo Bank) agree to perform, as
agents for their customers, administrative services, with respect to Fund
shares, which include aggregating and transmitting shareholder orders for
purchases, exchanges and redemptions; maintaining shareholder accounts and
records; and providing such other related services as the Trust or a shareholder
may reasonably request.  For providing shareholder services, a Servicing Agent
is entitled to a fee from the applicable Fund, on an annualized basis, of 0.25%
of the average daily net assets of the class of shares owned of record or
beneficially by the customers of the Servicing Agent during the period for which
payment is being made.  The Servicing Plan and related forms of shareholder
servicing agreements were approved by the Trust's Board of Trustees and  provide
that a Fund shall not be obligated to make

                                       35
<PAGE>

any payments under such Plans or related Agreements that exceed the maximum
amounts payable under the Conduct Rules of the NASD.

     General.  The Servicing Plan will continue in effect from year to year if
     -------
such continuance is approved by a majority vote of the Trustees of the Trust,
including a majority of the Trustees who are not "interested periods" (as
defined in the 1940 Act) of the Funds ("Non-Interested Trustees").  Any form of
Servicing Agreement related to the Servicing Plan also must be approved by such
vote of the Trustees and Non-Interested Trustees.  Servicing Agreements may be
terminated at any time, without payment of any penalty, by vote of a majority of
the Board of Trustees, including a majority of the Non-Interested Trustees.  No
material amendment to the Servicing Plan or related Servicing Agreements may be
made except by a majority of both the Trustees of the Trust and the Non-
Interested Trustees.

     The Servicing Plan requires that the Administrator shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Servicing Plan.

     Custodian.  Norwest Bank Minnesota, N.A. ("Norwest Bank") acts as Custodian
     ---------
for each Fund. The Custodian, among other things, maintains a custody account or
accounts in the name of each Fund, receives and delivers all assets for each
Fund upon purchase and upon sale or maturity, collects and receives all income
and other payments and distributions on account of the assets of each Fund, and
pays all expenses of each Fund.  For its services as Custodian, Norwest Bank is
entitled to receive a fee of 0.02% of the average daily net assets of each Fund.

     Fund Accountant.  Forum Financial Services, Inc. acts as Fund Accountant
     ---------------
for the Funds.  The Fund Accountant, among other things, computes net asset
values on a daily basis and performance calculations on a regular basis and as
requested by the Funds.  For providing such services, Forum is entitled to
receive a fee of [___.]

     Transfer and Dividend Disbursing Agent.  State Street Bank, acting through
     --------------------------------------
its affiliate Boston Financial Data Services ("BFDS"), acts as Transfer and
Dividend Disbursing Agent for the Funds.  For providing such services, BFDS is
entitled to receive a per-account fee of [0.04% of the average daily net assets
of each such account on an annual basis].

                           PERFORMANCE CALCULATIONS

     The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

                                       36
<PAGE>

     Performance information for a Fund or Class of shares in a Fund may be
useful in reviewing the performance of such Fund or Class of shares and for
providing a basis for comparison with investment alternatives.  The performance
of a Fund and the performance of a Class of shares in a Fund, however, may not
be comparable to the performance from investment alternatives because of
differences in the foregoing variables and differences in the methods used to
value portfolio securities, compute expenses and calculate performance.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

     Average Annual Total Return:  The Funds may advertise certain total return
     ---------------------------
information.  As and to the extent required by the SEC, an average annual
compound rate of return ("T") is computed by using the redeemable value at the
end of a specified period ("ERV") of a hypothetical initial investment ("P")
over a period of years ("n") according to the following formula:  P(1+T)/n/=ERV.

     Cumulative Total Return.  In addition to the above performance information,
     -----------------------
each Fund may also advertise the cumulative total return of the Fund.
Cumulative total return is based on the overall percentage change in value of a
hypothetical investment in the Fund, assuming all Fund dividends and capital
gain distributions are reinvested, without reflecting the effect of any sales
charge that would be paid by an investor, and is not annualized.

     Yield Calculations:  The Funds may, from time to time, include their yields
     ------------------
and effective yields in advertisements or reports to shareholders or prospective
investors.  Quotations of yield for the Funds are based on the investment income
per share earned during a particular seven-day or thirty-day period, less
expenses accrued during a period ("net investment income") and are computed by
dividing net investment income by the offering price per share on the last date
of the period, according to the following formula:

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

     where a = dividends and interest earned during the period; b = expenses
accrued for the period (net of reimbursements); c = the average daily number of
shares of each class outstanding during the period that were entitled to receive
dividends; and d = the maximum offering price per share each class of shares on
the last day of the period.

     Effective Yield:  Effective yields for the Funds are based on the change in
     ---------------
the value of a hypothetical investment (exclusive of capital changes) over a
particular thirty-day period, less a pro-rata share of each Fund's expenses
accrued over that period (the "base period"), and stated as a percentage of the
investment at the start of the base period (the "base period return").  The base
period return is then annualized multiplying by 365/30, with the resulting yield
figure carried to at least the nearest hundredth of one percent.  "Effective
yield" for the Funds assumes that all dividends received during the period have
been reinvested.  Calculation of "effective yield" begins with the same "base
period return" used in the calculation of yield, which is then annualized to
reflect weekly compounding pursuant to the following formula:

         Effective Thirty-Day Yield = [Base Period Return +1)365/30]-1

                                       37
<PAGE>

     Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown. Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.  In connection with communicating its yields or total return to
current or prospective shareholders, these figures may also be compared to the
performance of other mutual funds tracked by mutual fund rating services or to
unmanaged indices which may assume reinvestment of dividends but generally do
not reflect deductions for administrative and management costs.

     The yields for each class of shares will fluctuate from time to time,
unlike bank deposits or other investments that pay a fixed yield for a stated
period of time, and do not provide a basis for determining future yields since
they are based on historical data. Yield is a function of portfolio quality,
composition, maturity and market conditions as well as the expenses allocated to
a Fund or to a particular class of a Fund.

     In addition, investors should recognize that changes in the net asset
values of shares of each class of a Fund will affect the yield of the respective
class of shares for any specified period, and such changes should be considered
together with such class' yield in ascertaining such class' total return to
shareholders for the period. Yield information for each class of shares may be
useful in reviewing the performance of the class of shares and for providing a
basis for comparison with investment alternatives. The yield of each class of
shares, however, may not be comparable to the yields from investment
alternatives because of differences in the foregoing variables and differences
in the methods used to value portfolio securities, compute expenses and
calculate yield.

     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Trust may quote the performance or price-
earning ratio of a Fund or a Class of in advertising and other types of
literature as compared with the performance of the S&P Index, the Dow Jones
Industrial Average, the Lehman Brothers 20+ Treasury Index, the Lehman Brothers
5-7 Year Treasury Index, Donoghue's Money Fund Averages, Real Estate Investment
Averages (as reported by the National Association of Real Estate Investment
Trusts), Gold Investment Averages (provided by the World Gold Council), Bank
Averages (which is calculated from figures supplied by the U.S. League of
Savings Institutions based on effective annual rates of interest on both
passbook and certificate accounts), average annualized certificate of deposit
rates (from the Federal Reserve G-13 Statistical Releases or the Bank Rate
Monitor), the Salomon One Year Treasury Benchmark Index, the Consumer Price
Index (as published by the U.S. Bureau of Labor Statistics), other managed or
unmanaged indices or performance data of bonds, municipal securities, stocks or
government securities (including data provided by Ibbotson Associates), or by
other services, companies, publications or persons who monitor mutual funds on
overall performance or other criteria.  The S&P Index and the Dow Jones
Industrial Average are unmanaged indices of selected common stock prices.  The
performance of a Fund or a class also may be compared to that of other mutual
funds having similar objectives.  This comparative performance could be
expressed as a ranking prepared by Lipper Analytical Services, Inc., CDA
Investment Technologies, Inc., Bloomberg Financial Markets or Morningstar, Inc.,
independent services which monitor the performance of mutual funds.  The Funds'
performance will be calculated by relating net asset value per share of each
class at the beginning of a stated period to the net asset value of the
investment, assuming reinvestment of all gains distributions paid, at the end of
the period.  The

                                       38
<PAGE>

Funds' comparative performance will be based on a comparison of yields, as
described above, or total return, as reported by Lipper, Survey Publications,
Donoghue or Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a class of shares with the performance of a Fund's
competitors. Of course, past performance cannot be a guarantee of future
results.  The Trust also may include, from time to time, a reference to certain
marketing approaches of the Distributor, including, for example, a reference to
a potential shareholder being contacted by a selected broker or dealer. General
mutual fund statistics provided by the Investment Trust Institute may also be
used.

     The Trust also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
each class of shares of a Fund: (i) the Consumer Price Index may be used to
assess the real rate of return from an investment in each class of shares of a
Fund; (ii) other government statistics, including, but not limited to, The
Survey of Current Business, may be used to illustrate investment attributes of
each class of shares of a Fund or the general economic, business, investment, or
financial environment in which a Fund operates; (iii) the effect of tax-deferred
compounding on the investment returns of each class of shares of a Fund or on
returns in general, may be illustrated by graphs, charts, etc., where such
graphs or charts would compare, at various points in time, the return from an
investment in each class of shares of the Fund (or returns in general) on a tax-
deferred basis (assuming reinvestment of capital gains and dividends and
assuming one or more tax rates) with the return on a taxable basis; and (iv) the
sectors or industries in which the Fund invests may be compared to relevant
indices of stocks or surveys (e.g., S&P Industry Surveys) to evaluate the
historical performance or current or potential value of each class of shares of
a Fund with respect to the particular industry or sector.

     The Trust also may use, in advertisements and other types of literature,
information and statements: (1) showing that bank savings accounts offer a
guaranteed return of principal and a fixed rate of interest, but no opportunity
for capital growth; and (2) describing Wells Fargo Bank, and its affiliates and
predecessors, as one of the first investment managers to advise investment
accounts using asset allocation and index strategies.  The Trust also may
include in advertising and other types of literature information and other data
from reports and studies prepared by the Tax Foundation, including information
regarding federal and state tax levels and the related "Tax Freedom Day."

     The Trust also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by an NRSRO, such as Standard Poor's
Corporation. Such rating would assess the creditworthiness of the investments
held by a Fund.  The assigned rating would not be a recommendation to purchase,
sell or hold a Fund's shares since the rating would not comment on the market
price of a Fund's shares or the suitability of a Fund for a particular investor.
In addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to a Fund or its investments. The Trust may compare the performance of each
class of shares of a Fund with other investments which are assigned ratings by
NRSROs. Any such comparisons may be useful to investors who wish to compare each
class' past performance with other rated investments.

     From time to time, a Fund may use the following statements, or variations
thereof, in advertisements and other promotional materials:  "Wells Fargo Bank,
as a Shareholder Servicing

                                       39
<PAGE>

Agent for the Wells Fargo Funds Trust, provides various services to its
customers that are also shareholders of the Funds. These services may include
access to Wells Fargo Funds Trust's account information through Automated Teller
Machines (ATMs), the placement of purchase and redemption requests for shares of
the Funds through ATMs and the availability of combined Wells Fargo Bank and
Wells Fargo Funds Trust account statements."

     The Trust also may disclose, in advertising and other types of literature,
information and statements that Wells Capital Management, Inc. (formerly, Wells
Fargo Investment Management) a subsidiary of Wells Fargo Bank, is listed in the
top 100 by Institutional Investor magazine in its July 1997 survey "America's
Top 300 Money Managers." This survey ranks money managers in several asset
categories.  The Trust also may disclose in advertising and other types of sales
literature the assets and categories of assets under management by the Trust's
investment Advisor and the total amount of assets and mutual fund assets managed
by Wells Fargo Bank.  As of August 1, 1998, Wells Fargo Bank and its affiliates
provided investment advisory services for approximately $63 billion of assets of
individuals, trusts, estates and institutions and $32 billion of mutual fund
assets.

     The Trust may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels"). Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees. Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely through Electronic Channels. Advertising and other
literature may disclose that Wells Fargo Bank may maintain Web sites, pages or
other information sites accessible through Electronic Channels (an "Information
Site") and may describe the contents and features of the Information Site and
instruct investors on how to access the Information Site and open a Sweep
Account. Advertising and other literature may also disclose the procedures
employed by Wells Fargo Bank to secure information provided by investors,
including disclosure and discussion of the tools and services for accessing
Electronic Channels. Such advertising or other literature may include
discussions of the advantages of establishing and maintaining a Sweep Account
through Electronic Channels and testimonials from Wells Fargo Bank customers or
employees and may also include descriptions of locations where product
demonstrations may occur. The Trust may also disclose the ranking of Wells Fargo
Bank as one of the largest money managers in the United States.

                        DETERMINATION OF NET ASSET VALUE

     Net asset value per share for each class of the Funds is determined as of
the close of regular trading (currently 1:00 p.m. Pacific time/3:00 p.m. Central
time) on each day the New York Stock Exchange ("NYSE") is open for business.
Expenses and fees, including advisory fees, are accrued daily and are taken into
account for the purpose of determining the net asset value of the Funds' shares.

     Securities of a Fund for which market quotations are available are valued
at latest prices.  Any security for which the primary market is an exchange is
valued at the last sale price on such exchange on the day of valuation or, if
there was no sale on such day, the latest bid price quoted on such day.  In the
case of other Fund securities, including U.S. Government securities but
excluding

                                       40
<PAGE>

money market instruments and debt securities maturing in 60 days or less, the
valuations are based on latest quoted bid prices. Money market instruments and
debt securities maturing in 60 days or less are valued at amortized cost.
Futures contracts will be marked to market daily at their respective settlement
prices determined by the relevant exchange. Prices may be furnished by a
reputable independent pricing service approved by the Trust's Board of Trustees.
Prices provided by an independent pricing service may be determined without
exclusive reliance on quoted prices and may take into account appropriate
factors such as institutional-size trading in similar groups of securities,
yield, quality, coupon rate, maturity, type of issue, trading characteristics
and other market data. All other securities and other assets of a Fund for which
current market quotations are not readily available are valued at fair value as
determined in good faith by the Trust's Board of Trustees and in accordance with
procedures adopted by the Trustees.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

     Shares of the Funds may be purchased on any day the Funds are open for
business.  Each Fund is open for business each day the NYSE is open for trading
(a "Business Day"). Currently, the NYSE is closed 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 a "Holiday"). When any
Holiday falls on a weekend, the NYSE typically is closed on the weekday
immediately before or after such Holiday.

     Payment for shares may, in the discretion of the advisor, be made in the
form of securities that are permissible investments for the Funds.  For further
information about this form of payment please contact Stephens. In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that such Fund receives satisfactory
assurances that (i) it will have good and marketable title to the securities
received by it; (ii) that the securities are in proper form for transfer to the
Fund; and (iii) adequate information will be provided concerning the basis and
other matters relating to the securities.

     Under the 1940 Act, the Funds may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit.  The Trust may also redeem shares involuntarily or make payment
for redemption in securities or other property if it appears appropriate to do
so in light of the Trust's responsibilities under the 1940 Act.  In addition,
the Trust may redeem shares involuntarily to reimburse the Fund for any losses
sustained by reason of the failure of a shareholder to make full payment for
shares purchased or to collect any charge relating to a transaction effected for
the benefit of a shareholder which is applicable to shares of a Fund as provided
from time to time in the Prospectus.

                             PORTFOLIO TRANSACTIONS

     The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities.  Subject to policies
established by the Trust's Board of

                                       41
<PAGE>

Trustees, Wells Fargo Bank is responsible for each Fund's portfolio decisions
and the placing of portfolio transactions. In placing orders, it is the policy
of the Trust to obtain the best results taking into account the dealer's general
execution and operational facilities, the type of transaction involved and other
factors such as the dealer's risk in positioning the securities involved. While
Wells Fargo Bank generally seeks reasonably competitive spreads or commissions,
the Funds will not necessarily be paying the lowest spread or commission
available.

     Purchases and sales of non-equity securities usually will be principal
transactions.  Portfolio securities normally will be purchased or sold from or
to dealers serving as market makers for the securities at a net price.  Each of
the Funds also will purchase portfolio securities in underwritten offerings and
may purchase securities directly from the issuer.  Generally, municipal
obligations and taxable money market securities are traded on a net basis and do
not involve brokerage commissions.  The cost of executing a Fund's portfolio
securities transactions will consist primarily of dealer spreads and
underwriting commissions.  Under the 1940 Act, persons affiliated with the Trust
are prohibited from dealing with the Trust as a principal in the purchase and
sale of securities unless an exemptive order allowing such transactions is
obtained from the SEC or an exemption is otherwise available.  The Fund may
purchase securities from underwriting syndicates of which Stephens or Wells
Fargo Bank is a member under certain conditions in accordance with the
provisions of a rule adopted under the 1940 Act and in compliance with
procedures adopted by the Board of Trustees.

     Wells Fargo Bank, as Investment Advisor to the Funds, may, in circumstances
in which two or more dealers are in a position to offer comparable results for a
Fund portfolio transaction, give preference to a dealer that has provided
statistical or other research services to Wells Fargo Bank.  By allocating
transactions in this manner, Wells Fargo Bank is able to supplement its research
and analysis with the views and information of securities firms.  Information so
received will be in addition to, and not in lieu of, the services required to be
performed by Wells Fargo Bank under the Advisory Contracts, and the expenses of
Wells Fargo Bank will not necessarily be reduced as a result of the receipt of
this supplemental research information.  Furthermore, research services
furnished by dealers through which Wells Fargo Bank places securities
transactions for a Fund may be used by Wells Fargo Bank in servicing its other
accounts, and not all of these services may be used by Wells Fargo Bank in
connection with advising the Funds.

     Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
     ------------------
when Wells Fargo Bank deems portfolio changes appropriate.  Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the best interests of the
Funds and their shareholders. The portfolio turnover rate is calculated by
dividing the lesser of purchases or sales of portfolio securities by the average
monthly value of the Fund's portfolio securities. For purposes of this
calculation, portfolio securities exclude all securities having a maturity when
purchased of one year or less.  Portfolio turnover generally involves some
expenses to the Funds, including brokerage commissions or dealer mark-ups and
other transaction costs on the sale of securities and the reinvestment in other
securities.  Portfolio turnover also can generate short-term capital gain tax
consequences.  Portfolio turnover rate is not a limiting factor when Wells Fargo
Bank deems portfolio changes appropriate.

                                 FUND EXPENSES

     From time to time, Wells Fargo Bank and Stephens may waive fees from the
Funds in whole or in part.  Any such waiver will reduce expenses and,
accordingly, have a favorable impact on a Fund's performance.

     Except for the expenses borne by Wells Fargo Bank and Stephens, the Trust
bears all costs of its operations, including the compensation of its Trustees
who are not affiliated with Stephens or Wells Fargo Bank or any of their
affiliates; advisory, shareholder servicing and administration fees; payments
pursuant to any Plan; interest charges; taxes; fees and expenses of its
independent auditors, legal counsel, transfer agent and dividend disbursing
agent; expenses of redeeming shares; expenses of preparing and printing
Prospectuses (except the expense of printing and mailing Prospectuses used for
promotional purposes, unless otherwise payable pursuant to a Plan),
shareholders' reports, notices, proxy statements and reports to regulatory
agencies; insurance premiums and certain expenses relating to insurance
coverage; trade association membership dues; brokerage and other expenses
connected with the execution of portfolio transactions; fees and expenses of its
custodian, including those for keeping books and accounts and calculating the
net asset value per share of a Fund; expenses of shareholders' meetings;
expenses relating to the issuance, registration and qualification of a Fund's
shares; pricing services, organizational expenses and any extraordinary
expenses. Expenses attributable to the Fund are charged against Fund assets.
General expenses of the Trust are allocated among all of the funds of the Trust,
including the Funds, in a manner proportionate to the net assets of each Fund,
on a transactional basis, or on such other basis as the Trust's Board of
Trustees deems equitable.

                              FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes."  The Prospectuses of each Fund
describe generally the tax treatment of distributions by the Funds.  This
section of the SAI includes additional information concerning federal income
taxes.

     General.  The Trust intends to qualify each Fund as a regulated investment
     -------
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"), as long as such qualification is in the best interest of the Fund's
shareholders.  Each Fund will be treated as a separate entity for federal income
tax purposes.  Thus, the provisions of the Code applicable to regulated
investment companies generally will be applied to each Fund, rather than to the
Trust as a whole.  In addition, net capital gains, net investment income, and
operating expenses will be determined separately for each Fund.  As a regulated
investment company, each Fund will not be taxed on its net investment income and
capital gains distributed to its shareholders.

     Qualification as a regulated investment company under the Code requires,
among other things, that each Fund (a) derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including, but not limited to, gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) diversify

                                       43
<PAGE>

its holdings so that, at the end of each quarter of the taxable year, (i) at
least 50% of the market value of the Fund's assets is represented by cash,
government securities and other securities limited with respect to any one
issuer to an amount not greater than 5% of the Fund's assets and 10% of the
outstanding voting securities of such issuer, and (ii) not more than 25% of the
value of its assets is invested in the securities of any one issuer (other than
U.S. Government obligations and the securities of other regulated investment
companies), or in two or more issuers which the Fund controls and which are
determined to be engaged in the same or similar trades or businesses.

     The Funds also must distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income (which, for this
purpose, includes net short-term capital gains) earned in each taxable year.  In
general, these distributions must actually or be deemed to be made in the
taxable year.  However, in certain circumstances, such distributions may be made
in the 12 months following the taxable year.  Furthermore, distributions
declared in October, November or December of one taxable year and paid by
January 31 of the following taxable year will be treated as paid by December 31
of the first taxable year.  The Funds intend to pay out substantially all of
their net investment income and net realized capital gains (if any) for each
year.

     Excise Tax.  A 4% nondeductible excise tax will be imposed on each Fund
     ----------
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

     Taxation of Fund Investments.  Except as provided herein, gains and losses
     ----------------------------
on the sale of portfolio securities by a Fund will generally be capital gains
and losses.  Such gains and losses will ordinarily be long-term capital gains
and losses if the securities have been held by the Fund for more than one year
at the time of disposition of the securities.

     Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by a Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

     If an option granted by a Fund lapses or is terminated through a closing
transaction, such as a repurchase by the Fund of the option from its holder, the
Fund will realize a short-term capital gain or loss, depending on whether the
premium income is greater or less than the amount paid by the Fund in the
closing transaction.  Some realized capital losses may be deferred if they
result from a position which is part of a "straddle," discussed below.  If
securities are sold by the Fund pursuant to the exercise of a call option
written by it, the Fund will add the premium received to the sale price of the
securities delivered in determining the amount of gain or loss on the sale.  If
securities are purchased by a Fund pursuant to the exercise of a put option
written by it, such Fund will subtract the premium received from its cost basis
in the securities purchased.

                                       44
<PAGE>

     The amount of any gain or loss realized by a Fund on closing out a
regulated futures contract will generally result in a realized capital gain or
loss for federal income tax purposes. Regulated futures contracts held at the
end of each fiscal year will be required to be "marked to market" for federal
income tax purposes pursuant to Section 1256 of the Code.  In this regard, they
will be deemed to have been sold at market value. Sixty percent (60%) of any net
gain or loss recognized on these deemed sales, and sixty percent (60%) of any
net realized gain or loss from any actual sales, will generally be treated as
long-term capital gain or loss, and the remainder will be treated as short-term
capital gain or loss.  Transactions that qualify as designated hedges are
excepted from the "mark-to-market" rule and the "60%/40%" rule.

     Under Section 988 of the Code, a Fund generally will recognize ordinary
income or loss to the extent that gain or loss realized on the disposition of
portfolio securities is attributable to changes in foreign currency exchange
rates.  In addition, gain or loss realized on the disposition of a foreign
currency forward contract, futures contract, option or similar financial
instrument, or of foreign currency itself, will generally be treated as ordinary
income or loss.  The Funds will attempt to monitor Section 988 transactions,
where applicable, to avoid adverse Federal income tax impact.

     Offsetting positions held by a Fund involving certain financial forward,
futures or options contracts may be considered, for tax purposes, to constitute
"straddles."  "Straddles" are defined to include "offsetting positions" in
actively traded personal property.  The tax treatment of "straddles" is governed
by Section 1092 of the Code which, in certain circumstances, overrides or
modifies the provisions of Section 1256.  If a Fund were treated as entering
into "straddles" by engaging in certain financial forward, futures or option
contracts, such straddles could be characterized as "mixed straddles" if the
futures, forwards, or options comprising a part of such straddles were governed
by Section 1256 of the Code.  The Fund may make one or more elections with
respect to "mixed straddles."  Depending upon which election is made, if any,
the results with respect to the Fund may differ.  Generally, to the extent the
straddle rules apply to positions established by the Fund, losses realized by
the Fund may be deferred to the extent of unrealized gain in any offsetting
positions.  Moreover, as a result of the straddle and the conversion transaction
rules, short-term capital loss on straddle positions may be recharacterized as
long-term capital loss, and long-term capital gain may be characterized as
short-term capital gain or ordinary income.

     If a Fund enters into a "constructive sale" of any appreciated position in
stock, a partnership interest, or certain debt instruments, the Fund must
recognize gain (but not loss) with respect to that position.  For this purpose,
a constructive sale occurs when the Fund enters into one of the following
transactions with respect to the same or substantially identical property: (i) a
short sale; (ii) an offsetting notional principal contract; or (iii) a futures
or forward contract.

     Income and dividends received by the Funds from sources within foreign
countries may be subject to withholding and other taxes imposed by such
countries.

     Capital Gain Distributions.  Distributions which are designated by a Fund
     --------------------------
as capital gain distributions will be taxed to shareholders as long-term term
capital gain (to the extent such dividends do exceed the Fund's actual net
capital gains for the taxable year), regardless of how long a shareholder has
held Fund shares.  Such distributions will be designated as capital gain

                                       45
<PAGE>

distributions in a written notice mailed by the Fund to its shareholders not
later than 60 days after the close of the Fund's taxable year.

     Disposition of Fund Shares.  A disposition of Fund shares pursuant to a
     --------------------------
redemption (including a redemption in-kind) or an exchange will ordinarily
result in a taxable capital gain or loss, depending on the amount received for
the shares (or are deemed to be received in the case of an exchange) and the
cost of the shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred in acquiring the Fund's shares shall not be
taken into account (to the extent such previous sales charges do not exceed the
reduction in sales charges on the new purchase) for the purpose of determining
the amount of gain or loss on the disposition, but will be treated as having
been incurred in the acquisition of such other shares.  Also, any loss realized
on a redemption or exchange of shares of the Fund will be disallowed to the
extent that substantially identical shares are acquired within the 61-day period
beginning 30 days before and ending 30 days after the shares are disposed of.

     If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as a long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as a long-term capital loss to the extent of the designated capital gain
distribution.  In addition, if a shareholder holds Fund shares for six months or
less, any loss on the sale or exchange of those shares will be disallowed to the
extent of the amount of exempt-interest dividends received with respect to the
shares.  The Treasury Department is authorized to issue regulations reducing the
six months holding requirement to a period of not less than the greater of 31
days or the period between regular dividend distributions where a Fund regularly
distributes at least 90% of its net tax-exempt interest, if any.  No such
regulations have been issued as of the date of this SAI.  The loss disallowance
rules described in this paragraph do not apply to losses realized under a
periodic redemption plan.

     Federal Income Tax Rates.  As of the printing of this SAI, the maximum
     ------------------------
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 20%; and the maximum corporate tax rate applicable to
ordinary income and net capital gain is 35% (marginal tax rates may be higher
for some corporations to reduce or eliminate the benefit of lower marginal
income tax rates).  Naturally, the amount of tax payable by an individual or
corporation will be affected by a combination of tax laws covering, for example,
deductions, credits, deferrals, exemptions, sources of income and other matters.

     Backup Withholding.  The Trustees may be required to withhold, subject to
     ------------------
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, if the shareholder fails to certify that the Taxpayer
Identification Number ("TIN") provided is correct and that the shareholder is
not subject to

                                       46
<PAGE>

backup withholding, or if the IRS notifies the Trust that the shareholder's TIN
is incorrect or that the shareholder is subject to backup withholding. Such tax
withheld does not constitute any additional tax imposed on the shareholder, and
may be claimed as a tax payment on the shareholder's federal income tax return.
An investor must provide a valid TIN upon opening or reopening an account.
Failure to furnish a valid TIN to the Trust could also subject the investor to
penalties imposed by the IRS.

     Corporate Shareholders.  Corporate shareholders of the Funds may be
     ----------------------
eligible for the dividends-received deduction on dividends distributed out of a
Fund's net investment income attributable to dividends received from domestic
corporations, which, if received directly by the corporate shareholder, would
qualify for such deduction.  A distribution by a Fund attributable to dividends
of a domestic corporation will only qualify for the dividends-received deduction
if (i) the corporate shareholder generally holds the Fund shares upon which the
distribution is made for at least 46 days during the 90 day period beginning 45
days prior to the date upon which the shareholder becomes entitled to the
distribution; and (ii) the Fund generally holds the shares of the domestic
corporation producing the dividend income for at least 46 days during the 90 day
period beginning 45 days prior to the date upon which the Fund becomes entitled
to such dividend income.

     Foreign Shareholders.  Under the Code, distributions of net investment
     --------------------
income by the Funds to a nonresident alien individual, foreign trust (i.e.,
trust which a U.S. court is able to exercise primary supervision over
administration of that trust and one or more U.S. persons have authority to
control substantial decisions of that trust), foreign estate (i.e., the income
of which is not subject to U.S. tax regardless of source), foreign corporation,
or foreign partnership (a "foreign shareholder") will be subject to U.S.
withholding tax (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend paid by the Fund to a foreign
shareholder is "effectively connected" with a U.S. trade or business (or, if an
income tax treaty applies, is attributable to a U.S. permanent establishment of
the foreign shareholder), in which case the reporting and withholding
requirements applicable to U.S. persons will apply.  Distributions of net long-
term capital gains are generally not subject to tax withholding.

     New Regulations.  On October 6, 1997, the Treasury Department issued new
     ---------------
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1999, subject to certain
transition rules.  Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders that will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax advisors regarding the
New Regulations.

     Tax-Deferred Plan.  The shares of the Funds are available for a variety of
     -----------------
tax-deferred retirement and other plans, including Individual Retirement
Accounts ("IRA"), Simplified Employee Pension Plans ("SEP-IRA"), Savings
Incentive Match Plans for Employees ("SIMPLE plans"), Roth IRAs, and Education
IRAs, which permit investors to defer some of their income from taxes.
Investors should contact their selling agents for details concerning retirement
plans.

                                       47
<PAGE>

     Additional Considerations for the Tax-Free Income Fund.  If at least 50% of
     ------------------------------------------------------
the value of a regulated investment company's total assets at the close of each
quarter of its taxable years consists of obligations the interest on which is
exempt from federal income tax, it will qualify under the Code to pay "exempt-
interest dividends."  The Tax-Free Income Fund intends to so qualify and is
designed to provide investors with a high level of income exempt from federal
income tax.

     The portion of total dividends paid by the Tax-Free Income Fund with
respect to any taxable year that constitutes exempt-interest dividends will be
the same for all shareholders receiving dividends during such year.
Distributions of capital gains or from net investment income not attributable to
interest on the Fund's tax-exempt obligations will not constitute exempt-
interest dividends and will be taxable to its shareholders.  The exemption of
interest income derived from investments in tax-exempt obligations for federal
income tax purposes may not result in a similar exemption under the laws of a
particular state or local taxing authority.

     Not later than 60 days after the close of its taxable year, the Tax-Free
Income Fund will notify its shareholders of the portion of the dividends paid
with respect to such taxable year which constitutes exempt-interest dividends.
The aggregate amount of dividends so designated cannot exceed the excess of the
amount of interest excludable from gross income under Section 103 of the Code
received by the Fund during the taxable year over any amounts disallowed as
deductions under Sections 265 and 171(a)(2) of the Code.  Interest on
indebtedness incurred to purchase or carry shares of the Tax-Exempt Income Fund
will not be deductible to the extent that the Fund's distributions are exempt
from federal income tax.

     In addition, the federal alternative minimum tax ("AMT") rules ensure that
at least a minimum amount of tax is paid by taxpayers who obtain significant
benefit from certain tax deductions and exemptions.  Some of these deductions
and exemptions have been designated "tax preference items" which must be added
back to taxable income for purposes of calculating AMT.  Among the tax
preference items is tax-exempt interest from "private activity bonds" issued
after August 7, 1986.  To the extent that the Tax-Free Income Fund invests in
private activity bonds, its shareholders who pay AMT will be required to report
that portion of Fund dividends attributable to income from the bonds as a tax
preference item in determining their AMT.  Shareholders will be notified of the
tax status of distributions made by the Tax-Free Income Fund.  Persons who may
be "substantial users" (or "related persons" of substantial users) of facilities
financed by private activity bonds should consult their tax advisors before
purchasing shares in the Tax-Free Income Fund.  Furthermore, shareholders will
not be permitted to deduct any of their share of the Tax-Free Income Fund's
expenses in computing their AMT.  With respect to a corporate shareholder of the
Tax-Free Income Fund, exempt-interest dividends paid by the Fund is included in
the corporate shareholder's "adjusted current earnings" as part of its AMT
calculation, and may also affect its federal "environmental tax" liability.  As
of the printing of this SAI, individuals are subject to an AMT at a maximum rate
of 28% and corporations at a maximum rate of 20%.  Shareholders with questions
or concerns about AMT should consult their own tax advisors.

     Other Matters.  Investors should be aware that the investments to be made
     -------------
by the Funds may involve sophisticated tax rules that may result in income or
gain recognition by the Funds without corresponding current cash receipts.
Although the Funds will seek to avoid significant noncash income, such noncash
income could be recognized by the Funds, in which case the

                                       48
<PAGE>

Funds may distribute cash derived from other sources in order to meet the
minimum distribution requirements described above.

     The foregoing discussion and the discussions in the Prospectus applicable
to each shareholder address only some of the Federal tax considerations
generally affecting investments in the Funds.  Each investor is urged to consult
his or her tax advisor regarding specific questions as to federal, state, local
or foreign taxes.

                                 CAPITAL STOCK

     The Funds are eight of the funds in the Wells Fargo Funds Trust family of
funds.  The Trust was organized as a Delaware business trust on March 10, 1999.

     Most of the Trust's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors.  Certain of the Trust's funds also are authorized to issue
other classes of shares, which are sold primarily to institutional investors.
Each class of shares in a fund represents an equal, proportionate interest in a
fund with other shares of the same class.  Shareholders of each class bear their
pro rata portion of the fund's operating expenses, except for certain class-
specific expenses (e.g., any state securities registration fees, shareholder
servicing fees or distribution fees that may be paid under Rule 12b-1) that are
allocated to a particular class.  Please contact Shareholder Services at 1-800-
222-8222 if you would like additional information about other funds or classes
of shares offered.

     With respect to matters affecting one class but not another, shareholders
vote as a class; for example, the approval of a Plan.  Subject to the foregoing,
all shares of a Fund have equal voting rights and will be voted in the
aggregate, and not by series, except where voting by a series is required by law
or where the matter involved only affects one series.  For example, a change in
a Fund's fundamental investment policy affects only one series and would be
voted upon only by shareholders of the Fund involved.  Additionally, approval of
an advisory contract, since it affects only one Fund, is a matter to be
determined separately by Series.  Approval by the shareholders of one Series is
effective as to that Series whether or not sufficient votes are received from
the shareholders of the other Series to approve the proposal as to those Series.

     As used in the Prospectus and in this SAI, the term "majority," when
referring to approvals to be obtained from shareholders of a Class of shares of
a Fund, means the vote of the lesser of (i) 67% of the shares of the Class
represented at a meeting if the holders of more than 50% of the outstanding
shares of the Class are present in person or by proxy, or (ii) more than 50% of
the outstanding shares of the Class of the Fund.  The term "majority," when
referring to approvals to be obtained from shareholders of the Fund, means the
vote of the lesser of (i) 67% of the shares of the Fund represented at a meeting
if the holders of more than 50% of the outstanding shares of the Fund are
present in person or by proxy, or (ii) more than 50% of the outstanding shares
of the Fund.  The term "majority," when referring to the approvals to be
obtained from shareholders of the Trust as a whole, means the vote of the lesser
of (i) 67% of the Trust's shares represented at a meeting if the holders of more
than 50% of the Trust's outstanding shares are present in person or by proxy, or
(ii) more than 50% of the Trust's outstanding shares.

     Shareholders are not entitled to any preemptive rights. All shares, when
issued, will be fully paid and non-assessable by the Trust.  The Trust may
dispense with an annual meeting of shareholders in any year in which it is not
required to elect Trustees under the 1940 Act.

     Each share of a class of a Fund represents an equal proportional interest
in the Fund with each other share of the same class and is entitled to such
dividends and distributions out of the income earned on the assets belonging to
the Fund as are declared in the discretion of the Trustees. In the event of the
liquidation or dissolution of the Trust, shareholders of a Fund are entitled to
receive the assets attributable to that Fund that are available for
distribution, and a distribution of any general assets not attributable to a
particular Fund or portfolio that are available for distribution in such manner
and on such basis as the Trustees in their sole discretion may determine.

     Set forth below, as of [May 25, 1999], is the name, address and share
ownership of each person known by the Trust to have beneficial or record
ownership of 5% or more of a class of a Fund or 5% or more of the voting
securities as a whole.  The term "N/A" is used where a shareholder holds 5% or
more of a class, but less than 5% of a Fund as a whole.

                                    APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate and municipal bonds, municipal notes, and corporate and municipal
commercial paper.

     Corporate Bonds

     Moody's: The four highest ratings for corporate bonds are "Aaa," "Aa," "A"
and "Baa." Bonds rated "Aaa" are judged to be of the "best quality" and carry
the smallest amount of investment risk. Bonds rated "Aa" are of "high quality by
all standards," but margins of protection or other elements make long-term risks
appear somewhat greater than "Aaa" rated bonds. Bonds rated "A" possess many
favorable investment attributes and are considered to be upper medium grade
obligations. Bonds rated "Baa" are considered to be medium grade obligations;
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. Moody's
also applies numerical modifiers in its rating system: 1, 2 and 3 in each rating
category from "Aa" through "Baa" in its rating system. The modifier 1 indicates
that the security ranks in the higher end of its category; the modifier 2
indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks
in the lower end.

     S&P: The four highest ratings for corporate and municipal bonds are "AAA,"
"AA," "A" and "BBB." Bonds rated "AAA" have the "highest rating" assigned by S&P
and have "an extremely strong capacity" to pay interest and repay principal.
Bonds rated "AA" have a "very strong capacity" to pay interest and repay
principal and "differ from the highest rated obligations only in small degree."
Bonds rated "A" have a "strong capacity" to pay interest and repay principal,
but are "somewhat more susceptible" to adverse effects of changes in economic
conditions or other circumstances than bonds in higher rated categories. Bonds
rated "BBB" are regarded as having "adequate protection parameters" to pay
interest and repay principal, but changes in economic conditions or other
circumstances are more likely to lead to a "weakened capacity" to make such
repayments. The ratings from "AA" to "BBB" may be modified by the addition of a
plus or minus sign to show relative standing within the category.

     Commercial Paper

     Moody's: The highest rating for commercial paper is "P-1" (Prime-1).
Issuers rated "P-1" have a "superior ability for repayment of senior short-term
debt obligations." Issuers rated "P-2" (Prime-2) "have a strong capacity for
repayment of senior short-term debt obligations," but earnings trends, while
sound, will be subject to more variation.

                                      A-1
<PAGE>

     S&P: The "A-1" rating for commercial paper is rated "in the highest
category" by S&P and "the obligor's capacity to meet its financial commitment on
the obligation is strong." The "A-1+" rating indicates that said capacity is
"extremely strong." The A-2 rating indicates that said capacity is
"satisfactory," but that corporate and municipal commercial paper rated "A-2" is
"more susceptible" to the adverse effects of changes in economic conditions or
other circumstances than commercial paper rated in higher rating categories.

Summary Of Important Risks

 This section summarizes important risks that are common to all of the Funds
 described in this Prospectus.  Additional information about these and other
 risks is included in the individual Fund descriptions later in this Prospectus,
 under General Investment Risks beginning on page __ and in the Funds' Statement
 of Additional Information.  An investment in a Fund is not a deposit of Wells
 Fargo Bank and is not insured or guaranteed by the Federal Deposit Insurance
 Corporation.

 The Funds invest in debt securities, such as notes and bonds, which are subject
 to credit risk and interest rate risk.  Credit risk is the possibility that an
 issuer of an instrument will be unable to make interest payments or repay
 principal.  Changes in the financial strength of an issuer or changes in the
 credit rating of a security may affect its value.  Interest rate risk is the
 risk that interest rates may increase, which will reduce the resale value of
 securities in a Fund's investments, including U.S. Government obligations.
 Debt securities with longer maturities are generally more sensitive to interest
 rate changes than those with shorter maturities.  Changes in market interest
 rates do not affect the rate payable on debt securities held in a Fund, unless
 the securities have adjustable or variable rate features, which can reduce
 interest rate risk.  Changes in market interest rates may also extend or
 shorten the duration of certain types of instruments, such as asset-backed
 securities, and affect their value and the return on your investment.

 Although each of the Funds seeks to maintain a stable net asset value of $1.00
 per share, there is no assurance it will be able to do so.

 Performance History

 The Funds in this prospectus will commence operations in September 1999.  No
 performance information is given for the Funds because they will have been in
 operation for less than one year.

California Tax-Free Money Market Fund

Investment Objective
The California Tax-Free Money Market Fund seeks to obtain a high level of income
exempt from federal income tax and California personal income tax, while
preserving capital and liquidity, by investing in high-quality, short-term, U.S.
dollar-denominated money market instruments, primarily municipal obligations.

Investment Policies
We actively manage a portfolio of bonds, notes and commercial paper issued by or
on behalf of the state of California, its cities, municipalities, political
subdivisions and other public authorities.  Under normal market conditions we
invest substantially all of our assets in debt obligations with remaining
maturities of 397 days or less that are exempt from federal and California
personal income tax.  We maintain an overall dollar-weighted average maturity of
90 days or less.

Permitted Investments
Under normal market conditions, we invest:

 .  at least 80% of our assets in municipal obligations that provide income
   exempt from federal income and alternative minimum taxes;

 .  at least 65% of our assets in municipal obligations that pay interest exempt
   from California personal income taxes, although it is our intention to invest
   substantially all of our assets in such obligations; and

 .  in obligations rated within the two highest categories by nationally
   recognized ratings organizations.

We may also invest up to 20% of our assets in permitted taxable investments as a
defensive measure due to unusual market conditions or to maintain liquidity.

Important Risk Factors
You should consider both the General Investment Risks listed on page __ and the
specific risks listed below.  They are both important to your investment choice.

Since we invest heavily in California municipal obligations, events in
California are likely to affect the Fund's investments.  In addition, we may
invest up to 25% or more of our assets in California municipal obligations that
are related in such a way that political, economic or business developments
affecting one obligation would affect the others.  For example, we may own
different obligations that pay interest based on the revenue of similar
projects.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments.  No government agency either
directly or indirectly insures or guarantees the performance of the Fund.

Minnesota Money Market Fund

Investment Objective
The Minnesota Money Market Fund seeks to obtain a high level of income exempt
from federal regular income tax and regular Minnesota state income tax,
consistent with stability of principal.

Investment Policies
The Fund invests primarily in short-term Minnesota municipal securities,
including securities of states, territories, and possessions of the United
States which are not issued by or on behalf of Minnesota, or its political
subdivisions and financing authorities, but which provide income exempt from
federal regular income tax and the regular personal income taxes imposed by the
State of Minnesota consistent with stability of principal.

Permitted Investments
Under normal market conditions, we invest:

 .  at least 80% of our assets in short-term municipal obligations that provide
   income exempt from regular federal income and alternative minimum taxes;

 .  at least 65% of our assets in short-term municipal obligations that pay
   interest exempt from regular Minnesota personal income taxes, although it is
   our intention to invest substantially all of our assets in such obligations;
   and

 .  in obligations rated within the two highest categories by nationally
   recognized ratings organizations.

We may also invest up to 20% of our assets in permitted taxable investments as a
defensive measure due to unusual market conditions or to maintain liquidity.

Important Risk Factors
You should consider both the General Investment Risks listed on page __ and the
specific risks listed below. They are both important to your investment choice.

Since we invest heavily in Minnesota municipal obligations, events in Minnesota
are likely to affect the Fund's investments. In addition, we may invest up to
25% or more of out assets in Minnesota municipal obligations that are related in
such a way that political, economic or business developments affecting one
obligation would affect the others. For example, we may own different
obligations that pay interest based on the revenues of similar projects.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value. Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments. No government agency either
directly or indirectly insures or guarantees the performance of the Fund.

The Treasury Plus Money Market Fund seeks to provide investors with current
income and stability of principal.

Investment Policies
We actively manage a portfolio composed of obligations issued or guaranteed by
the U.S. Treasury, "plus" we invest in repurchase agreements and other debt
instruments collateralized or secured by Treasury obligations.  We buy
obligations with remaining maturities of 397 days or less.  We maintain an
overall dollar-weighted average maturity of 90 days or less.

Permitted Investments
Under normal market conditions, we invest:

 .  in U.S. Treasury obligations; and
 .  in repurchase agreements collateralized by U.S. Treasury obligations;

As a temporary defensive measure, or to maintain liquidity, we may invest in
shares of other money market funds that have similar investment objectives.
During such periods, the Fund may not achieve its objective.

Important Risk Factors
You should consider both the General Investment Risks listed on page __ and the
specific risks listed below.  They are both important to your investment choice.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments.  The U.S. Treasury does not
directly or indirectly insure or guarantee the performance of the Fund.
Investing in shares of other money market funds will subject the Fund to the
fees charged by the other funds, which will reduce returns from these
investments.

100% Treasury Money Market Fund

Investment Objective
The 100% Treasury Money Market Fund seeks to provide investors with stability of
principal and current income which is exempt from most state and local personal
income taxes.

Investment Policies
We actively manage a portfolio exclusively composed of obligations issued or
guaranteed by the U.S. Treasury.  We buy obligations with remaining maturities
of 397 days or less.  We maintain an overall dollar-weighted average maturity of
90 days or less.

Permitted Investments
Under normal market conditions, we invest:

 .  100% of our assets in U.S. Treasury obligations.

As a temporary defensive measure or to maintain liquidity, we may invest in
shares of other money market funds that have a substantially similar investment
objective.  During such periods, the Fund may not achieve its objective.

Important Risk Factors
You should consider both the General Investment Risks listed on page __ and the
specific risks listed below.  They are both important to your investment choice.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments.  The U.S. Treasury does not
directly or indirectly insure or guarantee the performance of the Fund.
Treasury obligations have historically involved little risk of loss of principal
if held to maturity.  However, fluctuations in market interest rates may cause
the market value of Treasury obligations in the Fund's portfolio to fluctuate.
Investing shares of other money market funds will subject the Fund to the fees
charged by the other funds, which will reduce returns from these investments.

Any capital gains realized by the Fund generally will not be exempt from state
and local taxes.  For more information, see "Taxes" on page __, and the
Statement of Additional Information.

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds.  Certain common risks are identified in the
Summary of Important Risks on page ___.  Other risks of mutual fund investing
include the following:

 .  Unlike bank deposits, such as CDs or savings accounts, mutual funds are not
   insured by the FDIC.

 .  We cannot guarantee that we will meet our investment objectives.  In
   particular, we cannot guarantee that we will be able to maintain a $1.00 per
   share net asset value.

 .  We do not guarantee the performance of a Fund, nor can we assure you that the
   market value of your investment will not decline. We will not "make good" any
   investment loss you may suffer, nor can anyone we contract with to provide
   certain services, such as selling agents or investment advisors, offer or
   promise to make good any such losses.

 .  Share prices -- and therefore the value of your investment -- will increase
   and decrease with changes in the value of the underlying securities and other
   investments. This is referred to as price volatility.

 .  Investing in any mutual fund, including those deemed conservative, involves
   risk, including the possible loss of any money you invest.

 .  An investment in a single Fund, by itself, does not constitute a complete
   investment plan.

 .  The Funds may invest a portion of their assets in U.S. Government
   obligations. It is important to recognize that the U.S. Government does not
   guarantee the market value or current yield of those obligations. Not all
   U.S. Government obligations are backed by the full faith and credit of the
   U.S. Treasury, and the U.S. Government's guarantee does not extend to the
   Funds themselves.

 .  The Funds may also use certain derivative instruments, such as options or
   futures contracts. The term "derivatives" covers a wide number of
   investments, but in general it refers to any financial instrument whose value
   is derived, at least in part, from the price of another security or a
   specified index, asset or rate. Some derivatives may be more sensitive to
   interest rate changes or market moves, and some may be susceptible to changes
   in yields or values due to their structure or contract terms.

What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Fund and a table showing some of the
additional investment practices that each Fund may use and the risks associated
with them.  Additional information about these practices is available in the
Statement of Additional Information.

Counter-Party Risk--The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule.  If an issuer does default,
the affected security could lose all of its value, or be renegotiated at a lower
interest rate or principal amount.  Affected securities might also lose
liquidity.  Credit risk also includes the risk that a party in a transaction may
not be able to complete the transaction as agreed.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value of
liquidity of investments in either country.

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security.  Generally, when interest rates increase, the value of
a debt security decreases.  The effect is usually more pronounced for securities
with longer dates to maturity.

                                       12

General Investment Risks (Cont'd)

Leverage Risk--The risk that an investment practice may increase a Fund's
exposure to market risk, interest rate risk or other risks by, in effect,
increasing assets available for investment.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of a stock, bond or other security will be
reduced by market activity.  This is a basic risk associated with all
securities.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.  Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Year 2000 Risk--The Funds' principal service providers have advised the Funds
that they are working on the necessary changes to their computer systems to
avoid any system failure based on an inability to distinguish the year 2000 from
the year 1900, and that they expect their systems to be adapted in time.  There
can, of course, be no assurance of success.  In addition, the companies or
entities in which the Funds invest also could be adversely impacted by the Year
2000 issue, especially foreign entities, which may be less prepared for Year
2000.  The extent of such impact cannot be predicted.

Investment Practice/Risk

The following table lists some of the additional investment practices of the
Funds, including some not disclosed in the Investment Objective and Investment
Policies sections of the Prospectus.  The risks indicated after the description
of the practice are NOT the only potential risks associated with that practice,
but are among the more prominent.  Market risk is assumed for each.  See the
Investment Objective and Investment Policies for each Fund or the Statement of
Additional Information for more information on these practices.

Investment practices and risk levels are carefully monitored.  We attempt to
ensure that the risk exposure for each Fund remains within the parameters of its
objective.

Remember, each Fund is designed to meet different investment needs and
objectives.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund.  You should also
see the Statement of Additional Information for additional information about the
investment practices and risks particular to each Fund.

Organization and Management of the Funds

A number of different entities provide services to the Funds.  This section
shows how the Funds are organized, lists the entities that perform different
services, and explains how these service providers are compensated.  Further
information is available in the Statement of Additional Information for the
Funds.

About Wells Fargo Funds Trust
Wells Fargo Funds Trust (the "Trust") was organized as a Delaware business trust
on March 10, 1999.  The Board of Trustees of the Trust supervises each Fund's
activities, monitors its contractual arrangements with various service providers
and decides upon matters of general policy.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds.  The holding company of Wells Fargo Bank, the investment advisor to
the Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998.  Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one Stagecoach or Norwest
Advantage Funds.  One of these predecessor funds is expected to be the
"accounting survivor," which means that its performance and financial statement
history of the predecessor fund will be assumed by the Wells Fargo Funds Trust
Fund.  The succession transactions are conditioned on shareholder approval by
the shareholders of the various Stagecoach and Norwest Advantage Funds.  The
Table on page __ identifies the Stagecoach and Norwest predecessor funds.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund paid on an annual basis for the services
described.

The Board of Trustees of Wells Fargo Funds Trust supervises the Funds'
activities and approves the selection of various companies hired to manage the
Funds' operation.  The major service providers are described in the diagram
below.  Except for the advisors, which require shareholder vote to change, if
the Board believes that it is in the best interests of the shareholders, it may
make a change in one of these companies.

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:

 .  As with all mutual fund investments, the price you pay to purchase shares or
   the price you receive when you redeem shares is not determined until after a
   request has been received in proper form.
 .  We determine the Net Asset Value ("NAV") of each Funds' shares each business
   day. The Funds are open Monday through Friday, and generally are closed on
   federal bank holidays. We determine the NAV by subtracting the Fund class's
   liabilities from its total assets, and then dividing the result by the total
   number of outstanding shares of that class. Each Fund's assets are valued
   using the amortized cost method, in accordance with Rule 2a-7 of the 1940
   Act. See the Statement of Additional Information for further disclosure.
 .  We process requests to buy or sell shares of the funds each business day.
   Requests we receive in proper form for the Treasury Plus Money Market Fund
   generally are processed at 12:00 p.m. (Pacific time) on the same day.
   Requests we receive in proper form for all other Funds generally are
   processed at 9:00 a.m. (Pacific time), on the same day. If the markets close
   early, the Funds may close early and may value their shares at earlier times
   under these circumstances. Any request we receive in proper form before these
   times is processed the same day. Requests we receive after the cutoff times
   are processed the next business day.

You can buy Fund shares:
 .  By opening an account directly with the Fund (simply complete and return a
   Wells Fargo Funds application with proper payment);
 .  Through a brokerage account with an approved selling agent; or
 .  Through certain retirement, benefits and pension plans, or through certain
   packaged investment products (please see the providers of the plan for
   instructions).

Minimum Investments:
 .  $1,000 per Fund minimum initial investment; or
 .  $100 per Fund if you use the Systematic Purchase Program; and
 .  $100 per Fund for all investments after your first.

  We may waive the minimum for Funds you purchase through certain retirement,
  benefit and pension plans, through certain packaged investment products, or
  for certain classes of shareholders as permitted by the SEC. Check the
  specific disclosure statements and applications for the program through which
  you intend to invest.

GENERAL NOTES FOR SELLING SHARES
- -------------------------------------------------------------------------------------------------
We determine the NAV for the Treasury Plus Fund at 12:00 p.m. (Pacific time), and for the
Minnesota Money Market, 100% Treasury Money Market and California Tax-Free Money Market Funds at
9:00 a.m. (Pacific time).
- -------------------------------------------------------------------------------------------------
Your redemptions are net of any applicable CDSC.
- -------------------------------------------------------------------------------------------------
We will process requests to sell shares at the first NAV calculated after a request in proper
form is received.  Requests received before the cutoff times are processed on the same business
day.
- -------------------------------------------------------------------------------------------------
If your purchased shares through a packaged investment product or retirement plan, read the
directions for selling shares provided by the product or plan.  There maybe special
requirements that supersede the directions in this Prospectus.
- -------------------------------------------------------------------------------------------------
We reserve the right to delay payment of a redemption so that we may be reasonably certain that
investments made by check or Systematic Purchase Plan have been collected.  Payments of
redemptions also may be delayed under extraordinary circumstances or as permitted by the SEC in
order to protect remaining shareholders.
- -------------------------------------------------------------------------------------------------
Generally, we pay redemption requests in cash, unless the redemption request is for more than
$250,000 or 1% of the net assets of the Fund by a single shareholder over any ninety-day
period.  If a request for a redemption is over these limits, it may be to the detriment of
existing shareholders to pay such redemption in cash.  Therefore, we may pay all or part of the
redemption in securities of equal value.

Exchanges

Exchanges between Wells Fargo Funds are two transactions:  a sale of one Fund
and the purchase of another.  In general, the same rules and procedures that
apply to sales and purchases apply to exchanges.  There are, however, additional
factors you should keep in mind while making or considering an exchange:

 .  You should carefully read the Prospectus for the Fund into which you wish to
   exchange.
 .  If you exchange between a money market fund and a Fund with a sales load, you
   will buy shares at the Public Offering Price (POP) of the new Fund and a
   sales load may be assessed.
 .  If you are making an initial investment into a new Fund through an exchange,
   you must exchange at least the minimum first purchase amount of the Fund you
   are redeeming, unless your balance has fallen below that amount due to market
   conditions.
 .  Any exchange between Fund you already own must meet the minimum redemption
   and subsequent purchase amounts for the Funds involved.
 .  Exchanges from any share class to a money market fund can only be re-
   exchanged for the original share class.
 .  In order to discourage excessive fund transaction expenses that must be borne
   by other shareholders, we reserve the right to limit or reject exchange
   orders. Generally, we will notify you 60 days in advance of any changes in
   your exchange privileges.
 .  You may exchange shares of the Funds for Class A, Class B or Class C shares
   of a non-money market fund.

Additional Services and Other Information

Automatic Programs:
These programs help you conveniently purchase and/or redeem shares each month.
Call Investor Services 1-800-222-8222 for more information.

 .  Systematic Purchase Plan - With this program, you can regularly purchase
   shares of a Wells Fargo Fund with money automatically transferred from a
   linked bank account. Simply select the Fund you would like to purchase,
   specify an amount of at least $100, and tell us the day of the month you
   would like the money invested. If you do not specify a date, we will transfer
   the money and invest in shares of the Fund you select on or about the 25th
   day of the month.

 .  Systematic Exchange Plan - With this program, you can regularly exchange
   shares of a Wells Fargo Fund you own for shares of another Wells Fargo Fund.
   The exchange amount must be at least $100, and the exchange will take place
   on or about the 25th of each month. See the "Exchanges" section of this
   prospectus for the conditions that apply to your shares. This feature may not
   be available for certain types of accounts.

 .  Systematic Withdrawal Plan - With this program, you can regularly redeem
   shares and receive the proceeds by check or by transfer to a linked bank
   account. Simply specify an amount of at least $100 and we will sell your
   shares equal to that amount on or about the 25th of each month. To
   participate in this program, you:

   .  must have a Fund account value at $10,000 or more;
   .  must have your distributions reinvested; and
   .  may not simultaneously participate in the Systematic Purchase Plan.

It generally takes about ten days to establish a plan once we have received your
instructions.  It generally takes about five days to change or cancel
participation in a plan.  We automatically cancel your program if the linked
bank account your specified is closed.

Dividend and Capital Gain Distributions Options
The Funds in this Prospectus declare dividends daily, pay dividends monthly, and
make capital gains distributions at least annually.

We offer the following distribution options:

 .  Automatic Reinvestment Option - Lets you buy new shares of the same class of
   the Fund that generated the distributions. The new shares are purchased at
   NAV generally on the day the income is paid. This option is automatically
   assigned to your account unless you specify another plan.

 .  Check Payment Option - Allows you to receive checks for distributions mailed
   to your address of record or to another name and address which you have
   specified in written, signature guaranteed instructions. If checks remain
   uncashed for six months or are undeliverable by the Post Office, we will
   reinvest the distributions at the earliest date possible.

Two Things to Keep In Mind About Distributions
Remember, distributions have the effect of reducing the NAV per share by the
amount distributed.  Also, distributions on new shares shortly after purchase
would be in effect a return of capital, although the distribution may still be
taxable to you.

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus.  The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder.  It
is not intended as substitute for careful tax planning.  You should consult your
tax advisor about your specific tax situation.  Federal income tax
considerations are discussed further in the Statement of Additional Information.

We will pass on to you net investment income and net short-term capital gains
earned by a Fund as dividend distributions.  In general, these are taxable to
you as ordinary income.  However, dividends distributed by the California Tax-
Free Money Market Fund which is attributable to the Fund's net interest income
from tax-exempt securities will not be subject to federal income tax.  A
substantial portion of dividends distributed by the California Tax-Free Money
Market Fund to noncorporate shareholders will also be exempt from California
income tax.  Dividend distributions derived from net investment income from the
100% Treasury Money Market Fund are exempt in most jurisdictions from state and
local personal income taxes, but may not be exempt from state and local
corporate income and/or franchise taxes.

We will pass on to you any net capital gains earned by a Fund as capital gain
distributions.  In general, these distributions will be taxable to you as long-
term capital gains, which may qualify for taxation at preferential rates in the
hands of non-corporate shareholders.  However, distributions declared in
October, November and December and distributed by the following January will be
taxable as if they were paid on December 31 of the year in which they were
declared.  We will notify you annually as to the status of your Fund
distributions.

If you buy shares of a Fund shortly before it distributes its annual gains, your
distribution from the Fund will, in effect, be a taxable return of part of your
investment.  Similarly, if you buy shares of a Fund that holds appreciated
securities in its portfolio, you will receive a taxable return of part of your
investment if and when the Fund sells the appreciated securities and realizes
the gain.  Some of the Funds have built up, or have the potential to build up,
high levels of unrealized appreciation.

Foreign shareholders may be subject to different tax treatment, including
withholding taxes.  In certain circumstances, U.S. residents will be subject to
back-up withholding taxes.

As long as the Fund continually maintains a $1.00 NAV, you ordinarily will not
recognize taxable gain or loss on the redemption or exchange of your Fund
Shares.

Summary Of Important Risks

This section summarizes important risks that are common to all of the Funds
described in this Prospectus.  Additional information about these and other
risks is included in the individual Fund descriptions later in this Prospectus,
under General Investment Risks beginning on page __ and in the Funds' Statement
of Additional Information.  An investment in a Fund is not a deposit of Wells
Fargo Bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation.

The Funds invest in debt securities, such as notes and bonds, which are subject
to credit risk and interest rate risk.  Credit risk is the possibility that an
issuer of an instrument will be unable to make interest payments or repay
principal.  Changes in the financial strength of an issuer or changes in the
credit rating of a security may affect its value.  Interest rate risk is the
risk that interest rates may increase, which will reduce the resale value of
securities in a Fund's investments, including U.S. Government obligations.  Debt
securities with longer maturities are generally more sensitive to interest rate
changes than those with shorter maturities.  Changes in market interest rates do
not affect the rate payable on debt securities held in a Fund, unless the
securities have adjustable or variable rate features, which can reduce interest
rate risk.  Changes in market interest rates may also extend or shorten the
duration of certain types of instruments, such as asset-backed securities, and
affect their value and the return on your investment.

Although each of the Funds seeks to maintain a stable net asset value of $1.00
per share, there is no assurance it will be able to do so.

Performance History

The Funds in this prospectus will commence operations in September 1999.  No
performance information is given for the Funds because they will have been in
operation for less than one year.

California Tax-Free Money Market Fund

Investment Objective
The California Tax-Free Money Market Fund seeks to obtain a high level of income
exempt from federal income tax and California personal income tax, while
preserving capital and liquidity, by investing in high-quality, short-term, U.S.
dollar-denominated money market instruments, primarily municipal obligations.

Investment Policies
We actively manage a portfolio of bonds, notes and commercial paper issued by or
on behalf of the state of California, its cities, municipalities, political
subdivisions and other public authorities.  Under normal market conditions we
invest substantially all of our assets in debt obligations with remaining
maturities of 397 days or less that are exempt from federal and California
personal income tax.  We maintain an overall dollar-weighted average maturity of
90 days or less.

Permitted Investments
Under normal market conditions, we invest:

 .    at least 80% of our assets in municipal obligations that provide income
     exempt from federal income and alternative minimum taxes;

 .    at least 65% of our assets in municipal obligations that pay interest
     exempt from California personal income taxes, although it is our intention
     to invest substantially all of our assets in such obligations; and

 .    in obligations rated within the two highest categories by nationally
     recognized ratings organizations.

We may also invest up to 20% of our assets in permitted taxable investments as a
defensive measure due to unusual market conditions or to maintain liquidity.

Important Risk Factors
You should consider both the General Investment Risks listed on page __ and the
specific risks listed below.  They are both important to your investment choice.

Since we invest heavily in California municipal obligations, events in
California are likely to affect the Fund's investments.  In addition, we may
invest up to 25% or more of our assets in California municipal obligations that
are related in such a way that political, economic or business developments
affecting one obligation would affect the others.  For example, we may own
different obligations that pay interest based on the revenue of similar
projects.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-tem instruments.  No government agency either
directly or indirectly insures or guarantees the performance of the Fund.

Permitted Investments

exempt from both federal income tax and California personal income tax:

 .    bonds, notes or commercial paper issued by or on behalf of the State of
     California, its cities, municipalities, political subdivisions and other
     public authorities; and

 .    obligations issued by the U.S. Virgin Islands, Puerto Rico and Guam, the
     interest of which also is exempt from federal income tax and California
     personal income tax.

Fund's assets in municipal obligations that provide income exempt from federal
income tax and not subject to the federal alternative minimum tax.

Investment Policies
The Fund invests primarily in short-term Minnesota municipal securities,
including securities of states, territories, and possessions of the United

 .    at least 80% of our assets in short-term municipal obligations that provide
     income exempt from regular federal income and alternative minimum taxes;

 .    at least 65% of our assets in short-term municipal obligations that pay
     interest exempt from regular Minnesota personal income taxes, although it
     is our intention to invest substantially all of our assets in such
     obligations; and

 .    in obligations rated within the two highest categories by nationally
     recognized ratings organizations.

We may also invest up to 20% of our assets in permitted taxable investments as a
defensive measure due to unusual market conditions or to maintain liquidity.

Important Risk Factors
You should consider both the General Investment Risks listed on page __ and the
specific risks listed below.  They are both important to your investment choice.

Since we invest heavily in Minnesota municipal obligations, events in Minnesota
are likely to affect the Fund's investments.  In addition, we may invest up to

such a way that political, economic or business developments affecting one
obligation would affect the others.  For example, we may own different

asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments.  No government agency either

asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments.  No government agency either
directly or indirectly insures or guarantees the performance of the Fund.

National Tax-Free Money Market Trust

Investment Objective
The National Tax-Free Money Market Trust seeks to provide investors with a high
level of income exempt from federal income tax, while preserving capital and
liquidity.

Investment Policies
We actively manage a portfolio of U.S. dollar-denominated, high-quality, short-
term instruments, primarily municipal obligations with remaining maturities of
397 days or less.  Among the municipal obligations we buy are bonds, notes and
commercial paper issued by or on behalf of the states, territories and
possessions of the United States and their political subdivisions and other
public authorities.  Under normal market conditions we invest substantially all
of our assets in debt obligations that are exempt from federal income tax.  We
maintain an overall dollar-weighted average maturity of 90 days or less.

Permitted Investments
Under normal market conditions, we invest:

 .    at least 80% of our net assets in municipal obligations the interest on
     which is exempt from federal income tax and not subject to the federal
     alternative minimum tax; and

 .    in obligations rated within the two highest categories by nationally
     recognized ratings organizations.

We may also invest up to 20% of our assets in permitted taxable investments as a
defensive measure due to unusual market conditions or to maintain liquidity.

Important Risk Factors
You should consider both the General Investment Risks listed on page __ and the
specific risks listed below.  They are both important to your investment choice.

Up to 25% or more of our assets invested in municipal obligations may be related
in such a way that political, economic or business developments affecting one
obligation would affect the others.  For example, we may own different
obligations that pay interest based on the revenue of similar projects.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments.  No government agency either
directly or indirectly insures or guarantees the performance of the Fund.

Overland Express Sweep Fund

Investment Objective
The Overland Express Sweep Fund seeks to provide investors with a high level of
current income, while preserving capital and liquidity.

Investment Policies
We pursue this objective by actively managing a portfolio consisting of a broad
range of U.S. dollar-denominated, high-quality money market instruments,
including debt obligations with remaining maturities of 397 days or less.  We
maintain an overall weighted average maturity of 90 days or less.  We may also
make certain other investment including, for example, repurchase agreements.

Permitted Investments
Under normal market conditions, we invest in:

 .    commercial paper rated at the date of purchase as "P-1" by Moody's or "A-
     1+" or "A-1" by S&P;

 .    negotiable certificates of deposit and banker's acceptances;

 .    repurchase agreements;

 .    U.S. Government obligations;

 .    short-term, U.S. dollar-denominated debt obligations of U.S. branches of
     foreign banks and foreign branches of U.S. banks; and

 .    shares of other money market funds.

Important Risk Factors
You should consider both the General Investment Risks beginning on page ___ and
the specific risks listed below.  They are both important to your investment
choice.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments.  No government agency either
directly or indirectly insures a guarantees the performance of the Fund.

Prime Investment Money Market Fund

Investment Objective
The Prime Investment Money Market Fund seeks to provide investors with a high
level of income exempt from federal income tax, while preserving capital and
liquidity.

Investment Policies
We actively manage a portfolio of U.S. dollar-denominated, high-quality, short-
term instruments, primarily municipal obligations with remaining maturities of
397 days or less.  Among the municipal obligations we buy are bonds, notes and
commercial paper issued by or on behalf of the states, territories and
possessions of the United States and their political subdivisions and other
public authorities.

The Fund may invest in obligations of financial institutions.  These include
negotiable certificates of deposit, bank notes, bankers' acceptances, and time
deposits of U.S. banks (including savings banks and savings associations),
foreign branches of U.S. banks, foreign banks and their non U.S. branches, U.S.
branches and agencies of foreign banks, and wholly-owned banking related
subsidiaries of foreign banks.  The Funds limit their investments in obligations
of financial institutions to instructions that at the time of investment have
total assets in excess of $1 billion, or the equivalent in other currencies.

Permitted Investments
Under normal market conditions, we invest:

 .    more than 25% of its total assets in the obligations of domestic and
     foreign financial institutions, their holding companies, and their
     subsidiaries.

The Fund may not:

 .    invest more than 25% of its total assets in any other single industry.

Important Risk Factors
You should consider both the General Investment Risks listed on page __ and the
specific risks listed below.  They are both important to your investment choice.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments.  No government agency either
directly or indirectly insures or guarantees the performance of the Fund.

There is the risk that foreign investments may be subject to political and
economic instability, the imposition or tightening of exchange controls or other
limitations on repatriation of foreign capital or nationalization, increased
taxation, or confiscation of investors' assets.  Also, the risk that the price
of a foreign issuer's securities may not reflect the issuer's condition because
there is not sufficient publicly available information about the issues.

100% Treasury Money Market Fund

Investment Objective
The 100% Treasury Money Market Fund seeks to provide investors with stability of
principal and current income which is exempt from most state and local personal
income taxes.

Investment Policies
We actively manage a portfolio exclusively composed of obligations issued or
guaranteed by the U.S. Treasury.  We buy obligations with remaining maturities
of 397 days or less.  We maintain an overall dollar-weighted average maturity of
90 days or less.

Permitted Investments
Under normal market conditions, we invest:

 .  100% of our assets in U.S. Treasury obligations.

As a temporary defensive measure or to maintain liquidity, we may invest in
shares of other money market funds that have a substantially similar investment
objective.  During such periods, the Fund may not achieve its objective.

Important Risk Factors
You should consider both the General Investment Risks listed on page __ and the
specific risks listed below.  They are both important to your investment choice.

There is no guarantee that we will be able to maintain a $1.00 per share net
asset value.  Generally, short-term funds do not earn as high a level of income
as funds that invest in longer-term instruments.  The U.S. Treasury does not
directly or indirectly insure or guarantee the performance of the Fund.
Treasury obligations have historically involved little risk of loss of principal
if held to maturity.  However, fluctuations in market interest rates may cause
the market value of Treasury obligations in the Fund's portfolio to fluctuate.
Investing shares of other money market funds will subject the Fund to the fees
charged by the other funds, which will reduce returns from these investments.

Any capital gains realized by the Fund generally will not be exempt from state
and local taxes.  For more information, see "Taxes" on page 39, and the
Statement of Additional Information.

General Investment Risks

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds.  Certain common risks are identified in the
Summary of Important Risks on page ___.  Other risks of mutual fund investing
include the following:

 .  Unlike bank deposits, such as CDs or savings accounts, mutual funds are not
   insured by the FDIC.
 .  We cannot guarantee that we will meet our investment objectives. In
   particular, we cannot guarantee that we will be able to maintain a $1.00 per
   share net asset value.
 .  We do not guarantee the performance of a Fund, nor can we assure you that the
   market value of your investment will not decline. We will not "make good" any
   investment loss you may suffer, nor can anyone we contract with to provide
   certain services, such as selling agents or investment advisors, offer or
   promise to make good any such losses.
 .  Share prices -- and therefore the value of your investment -- will increase
   and decrease with changes in the value of the underlying securities and other
   investments. This is referred to as price volatility.
 .  Investing in any mutual fund, including those deemed conservative, involves
   risk, including the possible loss of any money you invest.
 .  An investment in a single Fund, by itself, does not constitute a complete
   investment plan.
 .  The Funds may invest a portion of their assets in U.S. Government
   obligations. It is important to recognize that the U.S. Government does not
   guarantee the market value or current yield of those obligations. Not all
   U.S. Government obligations are backed by the full faith and credit of the
   U.S. Treasury, and the U.S. Government's guarantee does not extend to the
   Funds themselves.
 .  The Funds may also use certain derivative instruments, such as options or
   futures contracts. The term "derivatives" covers a wide number of
   investments, but in general it refers to any financial instrument whose value
   is derived, at least in part, from the price of another security or a
   specified index, asset or rate. Some derivatives may be more sensitive to
   interest rate changes or market moves, and some may be susceptible to changes
   in yields or values due to their structure or contract terms.

What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Fund and a table showing some of the
additional investment practices that each Fund may use and the risks associated
with them.  Additional information about these practices is available in the
Statement of Additional Information.

Counter-Party Risk--The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

Credit Risk--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule.  If an issuer does default,
the affected security could lose all of its value, or be renegotiated at a lower
interest rate or principal amount.  Affected securities might also lose
liquidity.  Credit risk also includes the risk that a party in a transaction may
not be able to complete the transaction as agreed.

Diplomatic Risk--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value of
liquidity of investments in either country.

Information Risk--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

Interest Rate Risk--The risk that changes in interest rates can reduce the value
of an existing security.  Generally, when interest rates increase, the value of
a debt security decreases.  The effect is usually more pronounced for securities
with longer dates to maturity.

                                       18
<PAGE>

General Investment Risks (Cont'd)

Leverage Risk--The risk that an investment practice may increase a Fund's
exposure to market risk, interest rate risk or other risks by, in effect,
increasing assets available for investment.

Liquidity Risk--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

Market Risk--The risk that the value of a stock, bond or other security will be
reduced by market activity.  This is a basic risk associated with all
securities.

Political Risk--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

Regulatory Risk--The risk that changes in government regulations will adversely
affect the value of a security.  Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

Year 2000 Risk--The Funds' principal service providers have advised the Funds
that they are working on the necessary changes to their computer systems to
avoid any system failure based on an inability to distinguish the year 2000 from
the year 1900, and that they expect their systems to be adapted in time.  There
can, of course, be no assurance of success.  In addition, the companies or
entities in which the Funds invest also could be adversely impacted by the Year
2000 issue especially foreign entities, which may be less prepared for Year
2000.  The extent of such impact cannot be predicted.

Investment Practice/Risk

The following table lists some of the additional investment practices of the
Funds, including some not disclosed in the Investment Objective and Investment
Policies sections of the Prospectus.  The risks indicated after the description
of the practice are NOT the only potential risks associated with that practice,
but are among the more prominent.  Market risk is assumed for each.  See the
Investment Objective and Investment Policies for each Fund or the Statement of
Additional Information for more information on these practices.

Investment practices and risk levels are carefully monitored.  We attempt to
ensure that the risk exposure for each Fund remains within the parameters of its
objective.

Remember, each Fund is designed to meet different investment needs and
objectives.

In addition to the general risks discussed above, you should carefully consider
and evaluate any special risks that may apply to investing in a particular Fund.
See the "Important Risk Factors" in the summary for each Fund.  You should also
see the Statement of Additional Information for additional information about the
investment practices and risks particular to each Fund.

Organization and Management of the Funds

A number of different entities provide services to the Funds.  This section
shows how the Funds are organized, lists the entities that perform different
services, and explains explains how these service providers are compensated.
Further information is available in the Statement of Additional Information for
the Funds.

About Wells Fargo Funds Trust
Wells Fargo Funds Trust (the "Trust") was organized as a Delaware business trust
on March 10, 1999.  The Board of Trustees of the Trust supervises each Fund's
activities, monitors its contractual arrangements with various service providers
and decides upon matters of general policy.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds.  The holding company of Wells Fargo Bank, the investment advisor to
the Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998.  Each of the Funds described in this prospectus
is intended to succeed to the assets and operations of one Stagecoach or Norwest
Advantage Funds, with the exception of the Minnesota Tax-Free Money Market Fund
that does not have a predecessor.  The performance and financial statement
history of the predecessor fund will be assumed by the Wells Fargo Funds Trust
Fund.  The succession transactions are conditioned on shareholder approval by
the shareholders of the various Stagecoach and Norwest Advantage Funds.  The
Table on page __ identifies the Stagecoach and Norwest predecessor funds.

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Fund class paid on an annual basis for the
services described.

The Board of Trustees of Wells Fargo Funds Trust supervises the Funds'
activities and approves the selection of various companies hired to manage the
Funds' operation.  The major service providers are described in the diagram
below.  Except for the advisors, which require shareholder vote to change, if
the Board believes that it is in the best interests of the shareholders it may
make a change in one of these companies.

Your Account

This section tells you how Fund shares are priced, how to open an account and
how to buy and sell Fund shares once your account is open.

Pricing Fund Shares:
 .  As with all mutual fund investments, the price you pay to purchase shares or
   the price you receive when you redeem shares is not determined until after a
   request has been received in proper form.
 .  We determine the Net Asset Value ("NAV") of each Funds' shares each business
   day. The Funds are open Monday through Friday, and generally are closed on
   federal bank holidays. We determine the NAV by subtracting the Fund class's
   liabilities from its total assets, and then dividing the result by the total
   number of outstanding shares of that class. Each Fund's assets are valued
   using the amortized cost method, in accordance with Rule 2a-7 of the 1940
   Act. See the Statement of Additional Information for further disclosure.
 .  We process requests to buy or sell shares of the funds each business day.
   Requests we receive in proper form for each Fund except the Money Market
   Trust and Prime Investment Money Market Fund generally are processed at 9:00
   a.m. (Pacific time) on the same day. Requests we receive in proper form for
   the Money Market Trust and Prime Investment Money Market Fund generally are
   processed at 12:00 p.m. (Pacific time), on the same day. If the markets close
   early, the Funds may close early and may value their shares at earlier times
   under these circumstances. Any request we receive in proper form before these
   times is processed the same day. Requests we receive after the cutoff times
   are processed the next business day.

Minimum Investments:
 .  Institutional shares require a minimum initial investment of $5,000,000.
 .  Service shares require a minimum initial investment of $100,000.
 .  Trust shares have no minimum investment requirement, but must be purchased
   only within certain trust accounts.

We may waive the minimum for Funds you purchase through certain retirement,
benefit and pension plans, through certain packaged investment products, or for
certain classes of shareholders as permitted by the SEC.  Check the specific
disclosure statements and applications for the program through which you intend
to invest.

Your Account (Cont'd)

How to Buy Shares
You can open a Fund account and buy Fund shares through an Institution through
which you have established a Customer Account.  Investors interested in
purchasing Institutional shares of the Funds should contact an account
representative at their Institution and should understand the following:

 .  Share purchases are made through a Customer Account at an Institution in
   accordance with the terms of the Customer Account involved;
 .  Institutions are usually the holders of record of Institutional shares held
   through Customer Accounts and maintain records reflecting their customers'
   beneficial ownership of the shares;
 .  Institutions are responsible for transmitting their customers' purchase and
   redemption orders to the Funds and for delivering required payment on a
   timely basis;
 .  The exercise of voting rights and the delivery of shareholder communications
   from the Fund is governed by the terms of the Customer Account involved; and
 .  Institutions may charge their customers account fees and may receive fees
   from us with respect to investments their customers have made with the Funds.
   See "Organization and Management of the Funds" for further details about
   these fees.

Selling Shares
Institutional shares must be redeemed in accordance with the account agreement
governing your Customer Account at the Institution.  Please read the Customer
Account agreement with your Institution for rules governing selling shares.

- --------------------------------------------------------------------------------
We will process requests to sell at the first NAV calculated after a request in
proper form is received. Requests received before the cutoff times are processed
on the same business day.
- --------------------------------------------------------------------------------
If your purchased shares through a packaged investment product or retirement
plan, read the directions for selling shares provided by the product or plan.
There maybe special requirements that supersede the directions in this
Prospectus.
- --------------------------------------------------------------------------------
We reserve the right to delay payment of a redemption so that we may be
reasonably certain that investments made by check or Systematic Purchase Plan
have been collected. Payments of redemptions also may be delayed under
extraordinary circumstances or as permitted by the SEC in order to protect
remaining shareholders.
- --------------------------------------------------------------------------------
Generally, we pay redemption requests in cash, unless the redemption request is
for more than $250,000 or 1% of the net assets of the Fund by a single
shareholder over any ninety-day period. If a request for a redemption is over
these limits, it may be to the detriment of existing shareholders to pay such
redemption in cash. Therefore, we may pay all or part of the redemption in
securities of equal value.

Exchanges

Exchanges between Stagecoach Funds are two transactions:  a sale of one Fund and
the purchase of another.  In general, the same rules and procedures that apply
to sales and purchases apply to exchanges.  There are, however, additional
factors you should keep in mind while making or considering an exchange:

 .  You should carefully read the Prospectus for the Fund into which you wish to
   exchange.
 .  Every exchange involves selling Fund shares and that sale may produce a
   capital gain or loss for federal income tax purposes.
 .  If you are making an initial investment into a new Fund through an exchange,
   you must exchange at least the minimum first purchase amount of the Fund you
   are redeeming, unless your balance has fallen below that amount due to market
   conditions.
 .  Any exchange between Funds you already own must meet the minimum redemption
   and subsequent purchase amounts for the Funds involved.
 .  In order to discourage excessive Fund transaction expenses that must be borne
   by other shareholders, we reserve the right to limit or reject exchange
   orders. Generally, we will notify you 60 days in advance of any changes in
   your exchange privileges.
 .  Shares of the Fund may be exchanged for other Institutional Class shares, for
   other Service Class shares, or for Class A shares in certain qualified
   accounts. Contact your account representative for further details.

Additional Services and Other Information

Automatic Programs:
These programs help you conveniently purchase and/or redeem shares each month.
Call Investor Services 1-800-222-8222 for more information.

 .  Systematic Purchase Plan - With this program, you can regularly purchase
   shares of a Wells Fargo Fund with money automatically transferred from a
   linked bank account. Simply select the Fund you would like to purchase,
   specify an amount of at least $100, and tell us the day of the month you
   would like the money invested. If you do not specify a date, we will transfer
   the money and invest in shares of the Fund you select on or about the 25th
   day of the month.

 .  Systematic Exchange Plan - With this program, you can regularly exchange
   shares of a Wells Fargo Fund you own for shares of another Wells Fargo Fund.
   The exchange amount must be at least $100, and the exchange will take place
   on or about the 25th of each month. See the "Exchanges" section of this
   prospectus for the conditions that apply to your shares. This feature may not
   be available for certain types of accounts.

 .  Systematic Withdrawal Plan - With this program, you can regularly redeem
   shares and receive the proceeds by check or by transfer to a linked bank
   account. Simply specify an amount of at least $100 and we will sell your
   shares equal to that amount on or about the 25th of each month. To
   participate in this program, you:

   .  must have a Fund account value at $10,000 or more;
   .  must have your distributions reinvested; and
   .  may not simultaneously participate in the Systematic Purchase Plan.

It generally takes about ten days to establish a plan once we have received your
instructions.  It generally takes about five days to change or cancel
participation in a plan.  We automatically cancel your program if the linked
bank account your specified is closed.

Dividend and Capital Gain Distributions Options
The Funds in this Prospectus declare dividends daily, pay dividends monthly, and
make capital gains distributions at least annually.

We offer the following distribution options:

 .  Automatic Reinvestment Option - Lets you buy new shares of the same class of
   the Fund that generated the distributions. The new shares are purchased at
   NAV generally on the day the income is paid. This option is automatically
   assigned to your account unless you specify another plan.

 .  Check Payment Option - Allows you to receive checks for distributions mailed
   to your address of record or to another name and address which you have
   specified in written, signature guaranteed instructions. If checks remain
   uncashed for six months or are undeliverable by the Post Office, we will
   reinvest the distributions at the earliest date possible.

Two Things to Keep In Mind About Distributions
Remember, distributions have the effect of reducing the NAV per share by the
amount distributed.  Also, distributions on new shares shortly after purchase
would be in effect a return of capital, although the distribution may still be
taxable to you.

Taxes
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus.  The discussion summarizes only some of the
important tax considerations that affect the Funds and you as a shareholder.  It
is not intended as substitute for careful tax planning.  You should consult your
tax advisor about your specific tax situation.  Federal income tax
considerations are discussed further in the Statement of Additional Information.

We will pass on to you net investment income and net short-term capital gains
earned by a Fund as dividend distributions.  In general, these are taxable to
you as ordinary income.  However, dividends distributed by the California Tax-
Free Money Market Fund which is attributable to the Fund's net interest income
from tax-exempt securities will not be subject to federal income tax.  A
substantial portion of dividends distributed by the California Tax-Free Money
Market Fund to noncorporate shareholders will also be exempt from California
income tax.  Dividend distributions derived from net investment income from the
100% Treasury Money Market Fund are exempt in most jurisdictions from state and
local personal income taxes, but may not be exempt from state and local
corporate income and/or franchise taxes.

We will pass on to you any net capital gains earned by a Fund as capital gain
distributions.  In general, these distributions will be taxable to you as long-
term capital gains, which may qualify for taxation at preferential rates in the
hands of non-corporate shareholders.  However, distributions declared in
October, November and December and distributed by the following January will be
taxable as if they were paid on December 31 of the year in which they were
declared.  We will notify you annually as to the status of your Fund
distributions.

If you buy shares of a Fund shortly before it distributes its annual gains, your
distribution from the Fund will, in effect, be a taxable return of part of your
investment.  Similarly, if you buy shares of a Fund that holds appreciated
securities in its portfolio, you will receive a taxable return of part of your
investment if and when the Fund sells the appreciated securities and realizes
the gain.  Some of the Funds have built up, or have the potential to build up,
high levels of unrealized appreciation.

Foreign shareholders may be subject to different tax treatment, including
withholding taxes.  In certain circumstances, U.S. residents will be subject to
back-up withholding taxes.

As long as the Fund continually maintains a $1.00 NAV, you ordinarily will not
recognize taxable gain or loss on the redemption or exchange of your Fund
Shares.

                            INVESTMENT RESTRICTIONS

     Fundamental Investment Policies
     -------------------------------

     Each Fund has adopted the following investment restrictions, all of which
are fundamental policies; that is, they may not be changed, without approval by
the holders of a majority (as defined in the Investment Company Act of 1940, as
amended (the "1940 Act")) of the outstanding voting securities of such Fund.

The Funds may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of a Fund's

                                       2
<PAGE>

investments in that industry would equal 25% of the current value of the Fund's
total assets, provided that there is no limitation with respect to investment in
securities issued or guaranteed by the United States Government, its agencies or
instrumentalities;

     (2)  purchase securities of any issuer if, as a result, with respect to 75%
of a Fund's total assets, more than 5% of the value of its total assets would be
invested in the securities of any one issuer or, with respect to 100% of its
assets, the Fund's ownership would be more than 10% of the outstanding voting
securities of such issuer.  This policy does not restrict a Fund's ability to
invest in securities issued or guaranteed by the U.S. Government, its agencies
and instrumentalities; or to invest substantially all of its assets in  the
portfolio of one or more open-end management investment companies pursuant to
Section 12 of the 1940 Act and the rules thereunder;

     (3)  borrow money except to the extent permitted by the 1940 Act, and the
rules, regulations and exemptions thereunder;

     (4)  issue senior securities  except to the extent permitted by the 1940
Act, and the rules, regulations and exemptions thereunder;

     (5)  make loans to other parties if, as a result, the aggregate value of
such loans would exceed one-third of a Fund's total assets.  For the purposes of
this limitation, entering into repurchase agreements, lending securities and
acquiring any debt securities are not deemed to be the making of loans;

     (6)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer and the later disposition of such securities in
accordance with a Fund's investment program may be deemed to be an underwriting;

     (7)  purchase or sell real estate unless acquired as a result of ownership
of securities or other instruments (but this shall not prevent the Fund from
investing in securities or other instruments backed by real estate or securities
of companies engaged in the real estate business); nor

     (8)  purchase or sell physical commodities unless acquired as a result of
ownership of securities or other instruments (but this shall not prevent the
Funds from purchasing or selling options and futures contracts, or from
investing in securities or other instruments backed by physical commodities.

     Non-Fundamental Investment Policies
     -----------------------------------

     Each Fund has adopted the following non-fundamental policies which may be
changed by a vote of a majority of the Trustees of the Trust or at any time
without approval of such Fund's shareholders.

                                       3
<PAGE>

     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of the 1940 Act, the rules thereunder, and
any orders obtained thereunder now or in the future. Funds in a master/feeder or
core/gateway structure, such as the Income Equity Fund, generally invest in the
securities of one or more open-end management investment companies pursuant to
various provisions of the 1940 Act. Other investment companies in which the
Funds invest can be expected to charge fees for operating expenses, such as
investment advisory and administration fees, that would be in addition to those
charged by a Fund.

     (2)  Each Fund may not invest or hold more than 15% of the Fund's net
assets in illiquid securities. For this purpose, illiquid securities include,
among others, (a) securities that are illiquid by virtue of the absence of a
readily available market or legal or contractual restrictions on resale, (b)
fixed time deposits that are subject to withdrawal penalties and that have
maturities of more than seven days, and (c) repurchase agreements not terminable
within seven days.

     (3)  Each Fund may invest in futures or options contracts regulated by the
CFTC for (i) bona fide hedging purposes within the meaning of the rules of the
CFTC and (ii) for other purposes if, as a result, no more than 5% of the Fund's
net assets would be invested in initial margin and premiums (excluding amounts
"in-the-money") required to establish the contracts.

          Each Fund (i) will  not hedge more than [50%] of its total assets by
selling futures contracts, buying put options, and writing call options (so
called "short positions"),  (ii) will not buy futures contracts or write put
options whose underlying value exceeds [25%] of the Fund's total assets, and
(iii) will not buy call options with a value exceeding [5%] of the Fund's total
assets.

     (4)  Each Fund may lend securities from its portfolio to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) up to
the limits established by and under the 1940 Act, including any exemptive relief
obtained thereunder, which limits are currently generally one-third of a Fund's
total assets. Any such loans of portfolio securities will be fully
collateralized based on values that are marked to market daily. [A Fund will not
enter into any portfolio security lending arrangement having a duration of
longer than one year.]

     (5)  Each Fund may not make investments for the purpose of exercising
control or management. (Investments by the Fund in entities created under the
laws of foreign countries solely to facilitate investment in securities in that
country will not be deemed the making of investments for the purpose of
exercising control.)

     (6)  Each Fund may not purchase securities on margin (except for short-term
credits necessary for the clearance of transactions).

     (7)  Each Fund may not sell securities short, unless it owns or has the
right to obtain securities equivalent in kind and amount to the securities sold
short (short sales "against the box"), and provided that transactions in futures
contracts and options are not deemed to constitute selling securities short.

                                       4
<PAGE>

Each Fund may not purchase interests, leases, or limited partnership interests
in oil, gas, or other mineral exploration or development programs.

        ADDITIONAL PERMITTED INVESTMENT ACTIVITIES AND ASSOCIATED RISKS

     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.

     Asset-Backed Securities
     -----------------------

     The Prime Investment Money Market, Treasury Plus Money Market and 100%
Treasury Money Market Funds may purchase asset-backed securities unrelated to
mortgage loans.  These asset-backed securities may consist of undivided
fractional interests in pools of consumer loans or receivables held in trust.
Examples include certificates for automobile receivables (CARS) and credit card
receivables (CARDS).  Payments of principal and interest on these asset-backed
securities are "passed through" on a monthly or other periodic basis to
certificate holders and are typically supported by some form of credit
enhancement, such as a letter of credit, surety bond, limited guaranty, or
subordination.  The extent of credit enhancement varies, but usually amounts to
only a fraction of the asset-backed security's par value until exhausted.
Ultimately, asset-backed securities are dependent upon payment of the consumer
loans or receivables by individuals, and the certificate holder frequently has
no recourse to the entity that originated the loans or receivables.  The actual
maturity and realized yield vary based upon the prepayment experience of the
underlying asset pool and prevailing interest rates at the time of prepayment.

     Bank Obligations
     ----------------

     The Prime Investment Money Market, Treasury Plus Money Market and 100%
Treasury Money Market Funds may invest in bank obligations, including
certificates of deposit, time deposits, bankers' acceptances and other short-
term obligations of domestic and foreign banks, foreign subsidiaries of domestic
banks, foreign branches of domestic banks, and domestic and foreign branches of
foreign banks, domestic savings banks and associations and other banking
institutions.  With respect to such securities issued by foreign branches of
domestic banks, foreign subsidiaries of domestic banks, and domestic and foreign
branches of foreign banks, a Fund may be subject to additional investment risks
that are different in some respects from those incurred by a fund which invests
only in debt obligations of U.S. domestic issuers.  Such risks include possible
future political and economic developments, the possible imposition of foreign
withholding taxes on interest income payable on the securities, the possible
establishment of exchange controls or the adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and interest
on these securities and the possible seizure or nationalization of foreign
deposits.  In addition, foreign branches of U.S. banks and foreign banks may be
subject to less stringent reserve requirements and to different accounting,
auditing, reporting and recordkeeping standards than those applicable to
domestic branches of U.S. banks.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

                                       5
<PAGE>

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate.  Time
deposits which may be held by a Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation ("FDIC").  Bankers' acceptances are
credit instruments evidencing the obligation of a bank to pay a draft drawn on
it by a customer.  These instruments reflect the obligation both of the bank and
of the drawer to pay the face amount of the instrument upon maturity.  The other
short-term obligations may include uninsured, direct obligations, bearing fixed,
floating- or variable-interest rates.

     Commercial Paper
     ----------------

     The Prime Investment Money Market, Treasury Plus Money Market and 100%
Treasury Money Market Funds may invest in commercial paper. Commercial paper
includes short-term unsecured promissory notes, variable rate demand notes and
variable rate master demand notes issued by domestic and foreign bank holding
companies, corporations and financial institutions as well as similar taxable
instruments issued by government agencies and instrumentalities.

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds, except the California Tax-Free Money Market Trust and California
Tax-Free Money Market Fund, may purchase floating- and variable-rate obligations
such as demand notes and bonds.  These obligations may have stated maturities in
excess of thirteen months, but they permit the holder to demand payment of
principal at any time, or at specified intervals not exceeding thirteen months.
Variable-rate demand notes include master demand notes that are obligations that
permit a Fund to invest fluctuating amounts, which may change daily without
penalty, pursuant to direct arrangements between the Fund, as lender, and the
borrower.  The interest rates on these notes fluctuates from time to time, but
the Funds may only invest in floating- or variable-rate securities that bear
interest at a rate that resets quarterly or more frequently and that resets
based on standard money market rate indices.  The issuer of such obligations
ordinarily has a corresponding right, after a given period, to prepay in its
discretion the outstanding principal amount of the obligations plus accrued
interest upon a specified number of days' notice to the holders of such
obligations.

     Because these obligations are direct lending arrangements between the
lender and borrower, it is not contemplated that such instruments generally will
be traded, and there generally is no established secondary market for these
obligations, although they are redeemable at face value.  Accordingly, where
these obligations are not secured by letters of credit or other credit support
arrangements, a Fund's right to redeem is dependent on the ability of the
borrower to pay principal and interest on demand.  Such obligations frequently
are not rated by credit rating agencies and each Fund may invest in obligations
which are not so rated only if the Advisor determines that at the time of
investment the obligations are of comparable quality to the other obligations in
which such Fund may invest.  The Advisor, on behalf of each Fund, considers on
an ongoing basis the creditworthiness of the issuers of the floating- and
variable-rate demand obligations in such Fund's portfolio.  No Fund will invest
more than 10% of the value of its total net assets in floating- or variable-rate
demand obligations whose demand feature

                                       6
<PAGE>

is not exercisable within seven days. Such obligations may be treated as liquid,
provided that an active secondary market exists.

     Foreign Obligations
     -------------------

     Each Fund, except the California Tax-Free Money Market Fund and California
Tax-Free Money Market Trust, may invest up to 25% of its assets in high-quality,
short-term (thirteen months or less) debt obligations of foreign branches of
U.S. banks or U.S. branches of foreign banks that are denominated in and pay
interest in U.S. dollars.  Investments in foreign obligations involve certain
considerations that are not typically associated with investing in domestic
obligations.  There may be less publicly available information about a foreign
issuer than about a domestic issuer.  Foreign issuers also are not subject to
the same uniform accounting, auditing and financial reporting standards or
governmental supervision as domestic issuers.  In addition, with respect to
certain foreign countries, taxes may be withheld at the source under foreign
income tax laws and there is a possibility of expropriation or confiscatory
taxation, political or social instability, or diplomatic developments that could
affect adversely investments in, the liquidity of, and the ability to enforce
contractual obligations with respect to, securities of issuers located in those
countries.

     Forward Commitments, When-Issued Purchases and Delayed-Delivery
     ---------------------------------------------------------------
     Transactions
     ------------

     The Money Market Trust, Prime Investment Money Market, Treasury Plus Money
Market and 100% Treasury Money Market Funds may purchase or sell securities on a
when-issued or delayed-delivery basis and make contracts to purchase or sell
securities for a fixed price at a future date beyond customary settlement time.
Securities purchased or sold on a when-issued, delayed-delivery or forward
commitment basis involve a risk of loss if the value of the security to be
purchased declines, or the value of the security to be sold increases, before
the settlement date.

     Each Fund will segregate cash, U.S. Government obligations or other high-
quality debt instruments in an amount at least equal in value to the Fund's
commitments to purchase when-issued securities.  If the value of these assets
declines, the Fund will segregate additional liquid assets on a daily basis so
that the value of the segregated assets is equal to the amount of such
commitments.

                                       7
<PAGE>

     Illiquid Securities
     -------------------

     The Funds, except the California Tax-Free Money Market Fund and California
Tax-Free Money Market Trust, may invest in securities not registered under the
1933 Act and other securities subject to legal or other restrictions on resale.
Because such securities may be less liquid than other investments, they may be
difficult to sell promptly at an acceptable price.  Delay or difficulty in
selling securities may result in a loss or be costly to a Fund.  Each Fund may
invest up to 10% of its assets in illiquid securities.

     Letters of Credit
     -----------------

     Certain of the debt obligations (including certificates of participation,
commercial paper and other short-term obligations) which the Funds, except the
Treasury Plus Money Market Fund, may purchase may be backed by an unconditional
and irrevocable letter of credit of a bank, savings and loan association or
insurance company which assumes the obligation for payment of principal and
interest in the event of default by the issuer.  Only banks, savings and loan
associations and insurance companies which, in the opinion of Wells Fargo Bank,
are of comparable quality to issuers of other permitted investments of each such
Fund may be used for letter of credit-backed investments.

     Money Market Instruments
     ------------------------

     The Overland Express Sweep Fund may invest in money market instruments.
Money market instruments consist of:  (a) short-term securities issued or
guaranteed by the U.S. Government, its agencies or instrumentalities (including
government-sponsored enterprises) (U.S. Government obligations"); (b) negotiable
certificates of deposit, bankers' acceptances and fixed time deposits and other
short-term obligations of domestic banks (including foreign branches) that have
more than $1 billion in total assets at the time of the investment and are
members of the Federal Reserve System or are examined by the Comptroller of the
Currency or whose deposits are insured by the Federal Deposit Insurance
Corporation ("FDIC"); (c) commercial paper rated at the date of purchase "Prime-
1" by Moody's Investors Service, Inc. ("Moody's") or "A-1+" or "A-1" by Standard
& Poor's Ratings Group ("S&P"), or, if unrated, by comparable qualify as
determined by Wells Fargo Bank; (d) certain repurchase agreements; and (e)
short-term U.S. dollar-denominated obligations of foreign banks (including U.S.
branches) that at the time of investment; (i) have more than $10 billion, or the
equivalent in other currencies, in total assets; (ii)  are among the largest
foreign banks in the world as determined on the basis of assets; and (iii) have
branches or agencies in the United States.

     Municipal Bonds.  The Fund may invest in municipal bonds.  As discussed in
     ---------------
the Fund's Prospectus, the two principal classifications of municipal bonds are
"general obligation" and "revenue" bonds.  Municipal bonds are debt obligations
issued to obtain Fund for various public purposes, including the construction of
a wide range of public facilities such as bridges, highways, housing, hospitals,
mass transportation, schools, streets, and water and sewer works.  Other
purposes for which municipal bonds may be issued include the refunding of
outstanding obligations and obtaining Fund for general operating expenses or to
loan to other public institutions and facilities.  Industrial development bonds
are a specific type of revenue bond

                                       8
<PAGE>

backed by the credit and security of a private user. Certain types of industrial
development bonds are issued by or on behalf of public authorities to obtain
Fund to provide privately-operated housing facilities, sports facilities,
convention or trade show facilities, airport, mass transit, port or parking
facilities, air or water pollution control facilities and certain local
facilities for water supply, gas, electricity, or sewage or solid waste
disposal. Assessment bonds, wherein a specially created district or project area
levies a tax (generally on its taxable property) to pay for an improvement or
project may be considered a variant of either category. There are, of course,
other variations in the types of municipal bonds, both within a particular
classification and between classifications, depending on numerous factors.

     Municipal Notes.  Municipal notes include, but are not limited to, tax
     ---------------
anticipation notes ("TANs"), bond anticipation notes ("BANs"), revenue
anticipation notes ("RANs") and construction loan notes.  Notes sold as interim
financing in anticipation of collection of taxes, a bond sale or receipt of
other revenues are usually general obligations of the issuer.

     TANs.  An uncertainty in a municipal issuer's capacity to raise taxes as a
     ----
result of such things as a decline in its tax base or a rise in delinquencies
could adversely affect the issuer's ability to meet its obligations on
outstanding TANs.  Furthermore, some municipal issuers mix various tax proceeds
into a general fund that is used to meet obligations other than those of the
outstanding TANs.  Use of such a general fund to meet various obligations could
affect the likelihood of making payments on TANs.

     BANs.  The ability of a municipal issuer to meet its obligations on its
     ----
BANs is primarily dependent on the issuer's adequate access to the longer term
municipal bond market and the likelihood that the proceeds of such bond sales
will be used to pay the principal of, and interest on, BANs.

     RANs.  A decline in the receipt of certain revenues, such as anticipated
     ----
revenues from another level of government, could adversely affect an issuer's
ability to meet its obligations on outstanding RANs.  In addition, the
possibility that the revenues would, when received, be used to meet other
obligations could affect the ability of the issuer to pay the principal of, and
interest on, RANs.

     The values of outstanding municipal securities will vary as a result of
changing market evaluations of the ability of their issuers to meet the interest
and principal payments (i.e., credit risk).  Such values also will change in
                        - -
response to changes in the interest rates payable on new issues of municipal
securities (i.e., market risk).  Should such interest rates rise, the values of
            - -
outstanding securities, including those held in the Fund's portfolio, will
decline and (if purchased at par value) sell at a discount.  If interests rates
fall, the values of outstanding securities will generally increase and (if
purchased at par value) sell at a premium.  Changes in the value of municipal
securities held in the Fund's portfolio arising from these or other factors will
cause changes in the net asset value per share of the Fund.

                                       9
<PAGE>

     Other Investment Companies
     --------------------------

     The Funds, except the California Tax-Free Money Market Fund and California
Tax-Free Money Market Trust, may invest in shares of other open-end management
investment companies, up to the limits prescribed in Section 12(d) of the 1940
Act.  Under the 1940 Act, a Fund's investment in such securities currently is
limited to, subject to certain exceptions, (i) 3% of the total voting stock of
any one investment company, (ii) 5% of such Fund's net assets with respect to
any one investment company and (iii) 10% of such Fund's net assets in aggregate.
Other investment companies in which the Funds invest can be expected to charge
fees for operating expenses such as investment advisory and administration fees,
that would be in addition to those charged by the Funds.

     Repurchase Agreements
     ---------------------

     The Funds, except the California Tax-Free Money Market Fund and California
Tax-Free Money Market Trust, may enter into repurchase agreements wherein the
seller of a security to the Fund agrees to repurchase that security from the
Fund at a mutually agreed upon time and price.  A Fund may enter into repurchase
agreements only with respect to securities that could otherwise be purchased by
the Fund.  All repurchase agreements will be fully collateralized at least 102%
based on values that are marked to market daily.  The maturities of the
underlying securities in a repurchase agreement transaction may be greater than
twelve months, although the maximum term of a repurchase agreement will always
be less than twelve months.  If the seller defaults and the value of the
underlying securities has declined, a Fund may incur a loss.  In addition, if
bankruptcy proceedings are commenced with respect to the seller of the security,
the Fund's disposition of the security may be delayed or limited.

     Each Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 10% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities.  A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Trustees  and that are not affiliated with the investment advisor.  The
Funds may participate in pooled repurchase agreement transactions with other
funds advised by Wells Fargo Bank.

     Short-Term Trading.
     ------------------

     The Money Market Trust and the National Tax Free Money Market Trust Funds
may attempt to increase yields by trading to take advantage of short-term market
variations.  This policy could result in high portfolio turnover but should not
adversely affect the Fund since it does not ordinarily pay brokerage commissions
on the purchase of short-term debt obligations.

     Unrated and Downgraded Investments
     ----------------------------------

     The Funds, except the California Tax-Free Money Market Fund and California
Tax-Free Money Market Trust, may purchase instruments that are not rated if, in
the opinion of the Advisor, such obligations are of comparable quality to other
rated investments that are permitted

                                       10
<PAGE>

to be purchased by the Funds. The Funds may purchase unrated instruments only if
they are purchased in accordance with the Funds' procedures adopted by Trust's
Board of Trustees in accordance with Rule 2a-7 under the 1940 Act. After
purchase by a Fund, a security may cease to be rated or its rating may be
reduced below the minimum required for purchase by the Fund. In the event that a
portfolio security ceases to be an "Eligible Security" or no longer "presents
minimal credit risks," immediate sale of such security is not required, provided
that the Board of Trustees has determined that disposal of the portfolio
security would not be in the best interests of the Fund.

     U.S. Government and U.S. Treasury Obligations
     ---------------------------------------------

     The Money Market Trust, Prime Investment Money Market, Treasury Plus Money
Market and 100% Treasury Money Market Funds may invest in obligations of
agencies and instrumentalities of the U.S. Government ("U.S. Government
obligations").  The Treasury Plus Money Market Fund may invest only in U.S.
Government obligations issued or guaranteed by the U.S. Treasury and in
repurchase agreements collateralized by U.S. Treasury Securities.  Payment of
principal and interest on U.S. Government obligations (i) may be backed by the
full faith and credit of the United States (as with U.S. Treasury bills and GNMA
certificates) or (ii) may be backed solely by the issuing or guaranteeing agency
or instrumentality itself (as with FNMA notes).  In the latter case investors
must look principally to the agency or instrumentality issuing or guaranteeing
the obligation for ultimate repayment, which agency or instrumentality may be
privately owned.  There can be no assurance that the U.S. Government will
provide financial support to its agencies or instrumentalities where it is not
obligated to do so.  In addition, U.S. Government obligations are subject to
fluctuations in market value due to fluctuations in market interest rates.  As a
general matter, the value of debt instruments, including U.S. Government
obligations, declines when market interest rates increase and rises when market
interest rates decrease.  Certain types of U.S. Government obligations are
subject to fluctuations in yield or value due to their structure or contract
terms.

                       SPECIAL CONSIDERATIONS AFFECTING
                       CALIFORNIA MUNICIPAL OBLIGATIONS

     Certain California constitutional amendments, legislative measures,
executive orders, civil actions and voter initiatives, as well as the general
financial condition of the state, could adversely affect the ability of issuers
of California municipal obligations to pay interest and principal on such
obligations.  The following information constitutes only a brief summary, does
not purport to be a complete description, and is based on information drawn from
official statements relating to securities offerings of the State of California
and various local agencies, available as of the date of this SAI.  While the
Company has not independently verified such information, it has no reason to
believe that such information is incorrect in any material respect.

     The California Economy and General Information.  From mid-1990 to late
1993, the state suffered a recession with the worst economic, fiscal and budget
conditions since the 1930s.  Construction, manufacturing (particularly related
to defense), exports and financial services, among others, were all severely
affected.  Job losses had been the worst of any post-war

                                       11
<PAGE>

recession. Unemployment reached 10.1% in January 1994, but fell sharply to 7.7%
in October and November 1994, reflecting the state's recovery from the
recession.

     The recession seriously affected California tax revenues, which basically
mirror economic conditions.  It also caused increased expenditures for health
and welfare programs.  In addition, the state has been facing a structural
imbalance in its budget with the largest programs supported by the General Fund
(e.g., K-12 schools and community colleges--also known as "K-14 schools," health
and welfare, and corrections) growing at rates higher than the growth rates for
the principal revenue sources of the General Fund.  As a result, the state
experienced recurring budget deficits in the late 1980s and early 1990s.  The
state's Controller reported that expenditures exceeded revenues for four of the
five fiscal years ending with 1991-92.  Moreover, California accumulated and
sustained a budget deficit in its Special Fund for Economic Uncertainties
("SFEU") approaching $2.8 billion at its peak at June 30, 1993.

     The accumulated budget deficits during the early 1990's, together with
expenditures for school funding which are not reflected in the state's budget,
and reduction of available internal borrowable funds, combined to significantly
deplete the state's cash resources to pay its ongoing expenses.  In order to
meet its cash needs, the state has had to rely for several years on a series of
external borrowings, including borrowings past the end of a fiscal year.  Such
borrowings are expected to continue in future fiscal years.  To meet its cash
flow needs in the 1995-96 fiscal year, California issued $2 billion of revenue
anticipation warrants which matured on June 28, 1996.  Because of the state's
deteriorating budget and cash situation, the rating agencies reduced the state's
credit ratings between October 1991 and July 1994.  Moody's Investors Service
lowered its rating from "Aa" to "A1," Standard & Poor's Ratings Group lowered
its rating from "AAA" to "A" and termed its outlook as "stable," and Fitch
Investors Service lowered its rating from "AA" to "A."

     However, since the start of 1994, California's economy has been recovering
steadily.  Employment has grew in excess of 500,000 during 1994 and 1995, and
400,000 additional jobs were created between the fourth quarter of 1996 and the
fourth quarter of 1997.  This trend is projected to continue through the rest of
the decade.  Unemployment, while remaining higher than the national average, has
come down from its 10% recession peak to under 6% in the Spring of 1998.
Because of the improving economy and California's fiscal austerity, the state
has had operating surpluses for its past five consecutive fiscal years through
1996-97 and has forecast an overall balanced budget by June 30, 2000.  Also,
Standard & Poors upgraded its rating of California municipal obligations back to
"A+" on July 15, 1996 and the projected level of the SFEU as of June 30, 1998
was $329 million.  However, the Asian economic difficulties since mid-1997 are
expected to have had a moderate dampening effect on California's economy.  Any
delay or reversal of the recovery may create new shortfalls in revenues.

     Local Governments.  On December 6, 1994, Orange County, California became
the largest municipality in the United States to file for protection under the
Federal Bankruptcy laws.  The filing stemmed from approximately $1.7 billion in
losses suffered by the county's investment pool because of investments in high
risk "derivative" securities.  In September 1995, California's legislature
approved legislation permitting the county to use for bankruptcy recovery

                                       12
<PAGE>

$820 million over 20 years in sales taxes previously earmarked for highways,
transit, and development. In June 1996, the county completed an $880 million
bond offering secured by real property owned by the county. In June 1996, the
county emerged from bankruptcy, and the county's investment rating by Standard &
Poors was "B" as of October 31, 1997.

     On January 17, 1994, an earthquake of the magnitude of an estimated 6.8 on
the Richter Scale struck Los Angeles County, California causing significant
damage to public and private structures and facilities.  While county residents
and businesses suffered losses totaling in the billions of dollars, the overall
effect of the earthquake on the county's and California's economy is not
expected to be serious.  However, Los Angeles County is experiencing financial
difficulty due in part to the severe operating deficits for the county's health
care system.  In August 1995, the credit rating of the county's long term bonds
was downgraded for the third time since 1992.  The county has received federal
and state assistance and the proposed fiscal 1999 budget for Los Angeles County
is the first in several years that does not begin with an operating deficit.
Even though the state has no existing obligations with respect to either Orange
County or Los Angeles County, the state may be required to intervene and provide
funding if the counties cannot maintain certain programs because of insufficient
resources.

     State Finances.  The monies of California are segregated into the General
Fund and approximately 600 Special Funds.  The General Fund consists of the
revenues received by the state's Treasury and not required by law to be credited
to any other fund, as well as earnings from state monies not allocable to
another fund.  The General Fund is the principal operating fund for the majority
of governmental activities and is the depository of most major revenue sources
of the state.  The General Fund may be expended as the result of appropriation
measures by California's Legislature and approved by the Governor, as well as
appropriations pursuant to various constitutional authorizations and initiative
statutes.

     The SFEU is funded with General Fund revenues and was established to
protect California from unforeseen revenue reductions and/or unanticipated
expenditure increases.  Amounts in the SFEU may be transferred by the state's
Controller to meet cash needs of the General Fund.  The Controller is required
to return monies so transferred without payment of interest as soon as there are
sufficient monies in the General Fund.  Any appropriation made from the SFEU is
deemed an appropriation from the General Fund, for budgeting and accounting
purposes.  For year-end reporting purposes, the Controller is required to add
the balance in the SFEU to the balance in the General Fund so as to show the
total monies then available for General Fund purposes.

     Inter-fund borrowing has been used for several years to meet temporary
imbalances of receipts and disbursements in the General Fund.  The 1998-99
Executive Budget projections submitted to the State Legislature in February
1998, forecast a 1999-00 General Fund budget gap of approximately $1.7 billion
and a 2000-01 gap of $3.7 billion.  As a result of changes made in the 1998-99
enacted budget, the 1999-00 gap is now expected to be roughly $1.3 billion, or
about $400 million less than previously projected, after application of reserves
created as part of the 1998-99 budget process.  Such reserves would not be
available against subsequent year imbalances.

     Changes in California Constitutional and Other Laws.  In 1978, California
voters approved an amendment to the California Constitution known as
"Proposition 13," which added Article XIIIA to the California Constitution.
Article XIIIA limits ad valorem taxes on real property and restricts the ability
of taxing authorities to increase real property taxes.  However, legislation
passed subsequent to Proposition 13 provided for the redistribution of
California's General Fund surplus to local agencies, the reallocation of
revenues to local agencies and the assumption of certain local obligations by
the state so as to assist California municipal issuers to raise revenue to pay
their bond obligations.  It is unknown whether additional revenue redistribution
legislation will be enacted in the future and whether, if enacted, such
legislation will provide sufficient revenue for such California issuers to pay
their obligations.  California is also subject to another Constitutional
Amendment, Article XIIIB, which may have an adverse impact on California state
and municipal issuers.  Article XIIIB restricts the state from spending certain
appropriations in excess of an appropriation's limit imposed for each state and
local government entity.  If revenues exceed such appropriation's limit, such
revenues must be returned either as revisions in the tax rates or fee schedules.

     In 1988, California voters approved "Proposition 98," which amended Article
XIIIB and Article XVI of the state's Constitution.  Proposition 98 (as modified
by "Proposition 111," which was enacted in 1990), changed state funding of
public education below the university level and the operation of the state's
appropriations limit, primarily by guaranteeing K-14 schools a minimum share of
General Fund revenues.  In 1986, California voters approved "Proposition 62,"
which provided in part that any tax for general governmental purposes imposed by
a local government be approved by a two-thirds vote of the governmental entity's
legislative body and by a majority of its electorate and that any special tax
imposed by a local government be approved by a two-thirds vote of the
electorate.  In September 1995, the California Supreme Court upheld the
constitutionality of Proposition 62, creating uncertainty as to the legality of
certain local taxes enacted by nonchartered cities in California without voter
approval.

     In 1996, California voters approved "Proposition 218," which added Articles
XIIIC and XIIID to the state's Constitution generally requiring voter approval
of most tax or fee increases by local governments and curtailing local
government use of benefit assessments to fund certain property-related services
to finance infrastructure.  Proposition 218 also limits the use of special
assessments or "property-related" fees to services or infrastructure that confer
a "special benefit" to specific property; police, fire and other services are
now deemed to benefit the public at large and, therefore, could not be funded by
special assessments.  Finally, the amendments enable the voters to use their
initiative power to repeal previously-authorized taxes, assessments, fees and
charges.  The interpretation and application of Proposition 218 will ultimately
be determined by the courts.  Proposition 218 is generally viewed as restricting
the fiscal flexibility of local governments, and for this reason, some ratings
of California cities and counties have been, and others may be, reduced.  It
remains to be seen, as such, what impact these Articles will have on existing
and future California security obligations.

     The Governor recently proposed that California reduce its Vehicle License
Fee (a personal property tax on the value of automobiles, the 'VLF') by 75% over
five years, by which time the tax cut would be more than $3.5 billion annually.
Under current law, the VLF is

                                       14
<PAGE>

entirely dedicated to city and county government, and the Governor proposed to
use the General Fund to offset the loss of VLF funds to local government. All of
the Governor's proposals must be negotiated with the State Legislature of
California as part of the annual budget process.

     Other Information.  Certain debt obligations held by the Fund may be
obligations payable solely from lease payments on real or personal property
leased to the state, cities, counties or their various public entities.
California law provides that a lessor may not be required to make payments
during any period that it is denied use and occupancy of the property in
proportion to such loss.  Moreover, the lessor only agrees to appropriate
funding for lease payments in its annual budget for each fiscal year.  In case
of a default under the lease, the only remedy available against the lessor is
that of reletting the property; no acceleration of lease payments is permitted.
Each of these factors presents a risk that the lease financing obligations held
by the Fund would not be paid in a timely manner.

     Each of the Trustees and officers listed above, act in the identical
capacities for Wells Fargo Variable Trust and Wells Fargo Core Trust
(collectively, the "Fund Complex").  Trustees of the Trust are compensated
annually by the Trust and by all the registrants in each fund complex they serve
beginning September 17, 1999, and beginning March 26, 1999, receive a per-
meeting fee of $250.  Trustees also are reimbursed for all out-of-pocket
expenses relating to attendance at board meetings.  The Trustees are compensated
by other companies and trusts within a fund complex for their services as
directors/trustees to such companies and trusts.  Currently the Trustees do not
receive any retirement benefits or deferred compensation from the Trust or any
other member of each fund complex.

     As of the date of this SAI, Trustees and Officers of the Trust as a group
beneficially owned less than 1% of the outstanding shares of the Company.

     Investment Advisor.  Wells Fargo Bank provides investment advisory services
     ------------------
to the Funds.  As Investment Advisor, Wells Fargo Bank furnishes investment
guidance and policy direction in connection with the daily portfolio management
of the Funds.  Wells Fargo Bank furnishes to the Trust's Board of Trustees
periodic reports on the investment strategy and performance of each Fund.  Wells
Fargo Bank provides the Funds with, among other things, money market security
and fixed-income research, analysis and statistical and economic data and
information concerning interest rate and securities markets trends, portfolio
composition, and credit conditions.

     As compensation for its advisory services, Wells Fargo Bank is entitled to
receive a monthly fee at the annual rates indicated below of each Fund's average
daily net assets:

     General.  Each Fund's Advisory Contract will continue in effect for more
     -------
than two years from the effective date provided the continuance is approved
annually (i) by the holders of a majority of the respective Fund's outstanding
voting securities or by the Trust's Board of Trustees and (ii) by a majority of
the Trustees of the Trust who are not parties to the Advisory Contract or
"interested persons" (as defined in the 1940 Act) of any such party.  A Fund's
Advisory Contract may be terminated on 60 days written notice by either party
and will terminate automatically if assigned.

     Investment Sub-Advisors.  Wells Fargo Bank has engaged Wells Capital
     -----------------------
Management ("WCM") to serve as Investment Sub-Advisor to the Money Market Trust.
Subject to the direction of the Trust's Board of Trustees and the overall
supervision and control of Wells Fargo Bank and the Trust, WCM makes
recommendations regarding the investment and reinvestment of the Funds' assets.
WCM furnishes to Wells Fargo Bank periodic reports on the investment activity
and performance of the Funds.  WCM and also furnishes such additional reports
and information as Wells Fargo Bank and the Trust's Board of Trustees and
officers may reasonably request.

     As compensation for its sub-advisory services, WCM is entitled to receive a
monthly fee equal to an annual rate of 0.05% of the first $1,000 million of the
Fund's average daily net assets and 0.04% of net assets over $1,000 million.
[WCM receives a minimum annual sub-advisory fee of $120,000 from the Fund.  This
minimum annual fee payable to WCM does not increase the advisory fee paid by
each Fund to Wells Fargo Bank.  These fees may be paid by Wells Fargo Bank or
directly by the Funds.  If the sub-advisory fee is paid directly by the Fund,
the compensation paid to Wells Fargo Bank for advisory fees will be reduced
accordingly.]

     Wells Fargo Bank has engaged Norwest Investment Management ("NIM") to serve
as Investment Sub-Advisor to each Fund other than the Money Market Trust.
Subject to the direction of the Trust's Board of Trustees and the overall
supervision and control of Wells Fargo Bank and the Trust, NIM makes
recommendations regarding the investment and reinvestment of the Funds' assets.
NIM furnishes to Wells Fargo Bank periodic reports on the investment activity
and performance of the Funds.  NIM also furnishes such additional reports and
information as Wells Fargo Bank and the Trust's Board of Trustees and officers
may reasonably request.

     Administrator.  The Trust has retained Wells Fargo Bank as Administrator on
     -------------
behalf of each Fund.  Under the Administration Agreement between Wells Fargo
Bank and the Trust, Wells Fargo Bank shall provide as administration services,
among other things:  (i) general supervision of the Funds' operations, including
coordination of the services performed by each Fund's investment Advisor,
transfer agent, custodian, shareholder servicing agent(s), independent auditors
and legal counsel, regulatory compliance, including the compilation of
information for documents such as reports to, and filings with, the SEC and
state securities commissions; and preparation of proxy statements and
shareholder reports for each Fund; and (ii) general supervision relative to the
compilation of data required for the preparation of periodic reports distributed
to the Trust's officers and Board of Trustees.  Wells Fargo Bank  also furnishes
office space and certain facilities required for conducting the Funds' business
together with ordinary clerical and bookkeeping services. The Administrator is
entitled to receive a fee of 0.15% of the average daily net assets on an annual
basis of each Fund.

     Distributor.  Stephens (the "Distributor"), located at 111 Center Street,
     -----------
Little Rock, Arkansas  72201, serves as Distributor for the Funds. The Money
Market Fund has adopted a distribution plan (a "Plan") under Section 12(b) of
the 1940 Act and Rule 12b-1 thereunder (the "Rule") for its Class B shares.  The
Plan was adopted by the Trust's Board of Trustees, including a majority of the
Trustees who were not "interested persons" (as defined in the 1940 Act) of the
Funds and who had no direct or indirect financial interest in the operation of
the Plan or in any agreement related to the Plan (the "Non-Interested
Trustees").

     Under the Plan and pursuant to the related Distribution Agreement, the
Class B shares of the Money Market Fund pay Stephens up to 0.75% of the average
daily net assets attributable to such Class as compensation for distribution-
related services or as reimbursement for distribution-related expenses.

     The actual fee payable to the Distributor is determined, within such
limits, from time to time by mutual agreement between the Trust and the
Distributor and will not exceed the maximum sales charges payable by mutual
funds sold by members of the National Association of Securities Dealers, Inc.
("NASD") under the Conduct Rules of the NASD.  The Distributor may enter into
selling agreements with one or more selling agents (which may include Wells
Fargo Bank and its affiliates) under which such agents may receive compensation
for distribution-related services from the Distributor, including, but not
limited to, commissions or other payments to such agents based on the average
daily net assets of Fund shares attributable to their customers.  The
Distributor may retain any portion of the total distribution fee payable
thereunder to compensate it for distribution-related services provided by it or
to reimburse it for other distribution-related expenses.

                                       19
<PAGE>

     General.  The Plan will continue in effect from year to year if such
     -------
continuance is approved by a majority vote of both the Trustees of the Trust and
the Non-Interested Trustees.  Any Distribution Agreement related to the Plan
also must be approved by such vote of the Trustees and the Non-Interested
Trustees.  Such Agreement will terminate automatically if assigned, and may be
terminated at any time, without payment of any penalty, by a vote of a majority
of the outstanding voting securities of the Class B shares of the Money Market
Fund or by vote of a majority of the Non-Interested Trustees on not more than 60
days' written notice.  The Plan may not be amended to increase materially the
amounts payable thereunder without the approval of a majority of the outstanding
voting securities of the Money Market Fund, and no material amendment to the
Plan may be made except by a majority of both the Trustees of the Trust and the
Non-Interested Trustees.

     The Plan requires that the Treasurer of Trust shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Plan.  The Rule also
requires that the selection and nomination of Trustees who are not "interested
persons" of the Trust be made by such disinterested Trustees.

     Wells Fargo Bank, an interested person (as that term is defined in Section
2(a)(19) of the 1940 Act) of the Trust, acts as a selling agent for the Money
Market Fund's Class B shares pursuant to selling agreements with Stephens
authorized under the Plan.  As a selling agent, Wells Fargo Bank has an indirect
financial interest in the operation of the Plan.  The Board of Trustees has
concluded that the Plan is reasonably likely to benefit the Money Market Fund
and its Class B shareholders because the Plan authorizes the relationships with
selling agents, including Wells Fargo Bank, that have previously developed
distribution channels and relationships with the retail customers that the Money
Market Fund Class B is designed to serve.  These relationships and distribution
channels are believed by the Board to provide potential for increased Money
Market Fund assets and ultimately corresponding economic efficiencies (i.e.,
lower per-share transaction costs and fixed expenses) that are generated by
increased assets under management.

     Shareholder Servicing Agent.  The Funds have approved a Shareholder
     ---------------------------
Servicing Plan and have entered into related Shareholder Servicing Agreements
with financial institutions, including Wells Fargo Bank, on behalf of certain of
its Class A, Class B, Institutional and Service Class shares.  Under the
agreements, Shareholder Servicing Agents (including Wells Fargo Bank) agree to
perform, as agents for their customers, administrative services, with respect to
Fund shares, which include aggregating and transmitting shareholder orders for
purchases, exchanges and redemptions; maintaining shareholder accounts and
records; and providing such other related services as the Trust or a shareholder
may reasonably request.  For providing shareholder services, a Servicing Agent
is entitled to a fee from the applicable Fund, on an annualized basis, of the
average daily net assets of the class of shares owned of record or beneficially
by the customers of the Servicing Agent during the period for which payment is
being made.  The amounts payable under the Shareholder Servicing Plan and
Agreements are shown below.  The Servicing Plan and related Shareholder
Servicing Agreements were approved by the Trust's Board of Trustees and provide
that a Fund shall not be obligated to make any payments under such Plan or
related Agreements that exceed the maximum amounts payable under the Conduct
Rules of the NASD.

     General.  The Servicing Plan will continue in effect from year to year if
     -------
such continuance is approved by a majority vote of the Trustees of the Trust,
including a majority of the Trustees who are not "interested persons" (as
defined in the 1940 Act) of the Funds ("Non-Interested Trustees").  Any form of
Servicing Agreement related to the Servicing Plan also must be approved by such
vote of the Trustees and the Non-Interested Trustees.  Servicing Agreements may
be terminated at any time, without payment of any penalty, by vote of a majority
of the Board of Trustees, including a majority of the Non-Interested Trustees.
No material amendment to the Servicing Plan or related Servicing Agreements may
be made except by a majority of both the Trustees of the Trust and the Non-
Interested Trustees.

     The Servicing Plan requires that the Administrator shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Servicing Plan.

or accounts in the name of each Fund, receives and delivers all assets for each
Fund upon purchase and upon sale or maturity, collects and receives all income
and other payments and distributions on account of the assets of each Fund and
pays all expenses of each Fund.  For its services as Custodian, Norwest Bank is
entitled to receive fees as follows:  0.02% of the average daily net assets of
each Fund.

     Fund Accountant.  Forum Financial Services, Inc. acts as Fund Accountant
     ---------------
for the Funds.  The Fund Accountant, among other things, computes net asset
values on a daily basis and performance calculations on a regular basis and as
requested by the Funds.  For providing such services, Forum is entitled to
receive a fee of [___.]

     Transfer and Dividend Disbursing Agent.  State Street Bank, acting through
     --------------------------------------
its affiliate Boston Financial Data Services ("BFDS"), acts as Transfer and

                           PERFORMANCE CALCULATIONS

     The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

     Performance information for a Fund or Class of shares in a Fund may be
useful in reviewing the performance of such Fund or Class of shares and for
providing a basis for comparison with investment alternatives.  The performance
of a Fund and the performance of a Class of shares in a Fund, however, may not
be comparable to the performance from investment alternatives because of
differences in the foregoing variables and differences in the methods used to
value portfolio securities, compute expenses and calculate performance.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year.

     Average Annual Total Return:  The Funds may advertise certain total return
     ---------------------------
information.  As and to the extent required by the SEC, an average annual
compound rate of return ("T") is computed by using the redeemable value at the
end of a specified period ("ERV") of a hypothetical initial investment ("P")
over a period of years ("n") according to the following formula: P(1+T)/n/=ERV.

     Cumulative Total Return:  In addition to the above performance information,
     -----------------------
each Fund may also advertise the cumulative total return of the Fund.
Cumulative total return is based on the overall percentage change in value of a
hypothetical investment in the Fund, assuming all Fund dividends and capital
gain distributions are reinvested, without reflecting the effect of any sales
charge that would be paid by an investor, and is not annualized.

     Yield Calculations:  The Funds may, from time to time, include their
     ------------------
yields, tax-equivalent yields (if applicable) and effective yields in
advertisements or reports to shareholders or prospective investors.  Quotations
of yield for the Funds are based on the investment income per share earned
during a particular seven-day or thirty-day period, less expenses accrued during
a period ("net investment income") and are computed by dividing net investment
income by the offering price per share on the last date of the period, according
to the following formula:

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

                                       22
<PAGE>

     where a = dividends and interest earned during the period, b = expenses
accrued for the period (net of any reimbursements), c = the average daily number
of shares outstanding during the period that were entitled to receive dividends,
and d = the maximum offering price per share on the last day of the period.

     Tax-Equivalent Yield:  Quotations of tax-equivalent yield for a Tax-Free
     --------------------
Fund are calculated according the following formula:

                       TAX EQUIVALENT YIELD = ( E ) + t
                                               ---
                                               1 - p
                            E = Tax-exempt yield
                            p = stated income tax rate
                            t = taxable yield

     Effective Yield:  Effective yields for the Funds are based on the change in
     ---------------
the value of a hypothetical investment (exclusive of capital changes) over a
particular seven-day (or thirty-day) period, less a pro-rata share of each
Fund's expenses accrued over that period (the "base period"), and stated as a
percentage of the investment at the start of the base period (the "base period
return").  The base period return is then annualized multiplying by 365/7 (or
365/30 for thirty-day yield), with the resulting yield figure carried to at
least the nearest hundredth of one percent.  "Effective yield" for the Funds
assumes that all dividends received during the period have been reinvested.
Calculation of "effective yield" begins with the same "base period return" used
in the calculation of yield, which is then annualized to reflect weekly
compounding pursuant to the following formula:

          Effective Seven-Day Yield = [(Base Period Return +1)365/7]-1

     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Trust may quote the performance or price-
earning ratio of a Fund or Class in advertising and other types of literature as
compared to the performance of the S&P Index, the Dow Jones Industrial Average,
the Lehman Brothers 20+ Treasury Index, the Lehman Brothers 5-7 Year Treasury
Index, Donoghue's Money Fund Averages, Real Estate Investment Averages (as
reported by the National Association of Real Estate Investment Trusts), Gold
Investment Averages (provided by World Gold Council), Bank Averages (which are
calculated from figures supplied by the U.S. League of Savings Institutions
based on effective annual rates of interest on both passbook and certificate
accounts), average annualized certificate of deposit rates (from the Federal
Reserve G-13 Statistical Releases or the Bank Rate Monitor), the Salomon One
Year Treasury Benchmark Index, the Consumer Price Index (as published by the
U.S. Bureau of Labor Statistics), other managed or unmanaged indices or
performance data of bonds, municipal securities, stocks or government securities
(including data provided by Ibbotson Associates), or by other services,
companies, publications or persons who monitor mutual funds on overall
performance or other criteria.  The S&P Index and the Dow Jones Industrial
Average are unmanaged indices of selected common stock prices.  The performance
of the Funds or a Class also may be compared to that of other mutual funds
having similar objectives.  This comparative performance could be expressed as a
ranking prepared by Lipper Analytical Services, Inc., CDA

                                       23
<PAGE>

Investment Technologies, Inc., Bloomberg Financial Markets or Morningstar, Inc.,
independent services which monitor the performance of mutual funds. The Funds'
performance will be calculated by relating net asset value per share at the
beginning of a stated period to the net asset value of the investment, assuming
reinvestment of all gains distributions and dividends paid, at the end of the
period. The Funds' comparative performance will be based on a comparison of
yields, as described above, or total return, as reported by Lipper, Survey
Publications, Donoghue or Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Funds or a Class with that of competitors.  Of course, past
performance cannot be a guarantee of future results.  The Trust also may
include, from time to time, a reference to certain marketing approaches of the
Distributor, including, for example, a reference to a potential shareholder
being contacted by a selected broker or dealer.  General mutual fund statistics
provided by the Investment Company Institute may also be used.

     The Trust also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
the Fund:  (i) the Consumer Price Index may be used to assess the real rate of
return from an investment in a Fund; (ii) other government statistics,
including, but not limited to, The Survey of Current Business, may be used to
illustrate investment attributes of a Fund or the general economic, business,
investment, or financial environment in which a Fund operates; (iii) the effect
of tax-deferred compounding on the investment returns of a Fund, or on returns
in general, may be illustrated by graphs, charts, etc., where such graphs or
charts would compare, at various points in time, the return from an investment
in a Fund (or returns in general) on a tax-deferred basis (assuming reinvestment
of capital gains and dividends and assuming one or more tax rates) with the
return on a taxable basis; and (iv) the sectors or industries in which a Fund
invests may be compared to relevant indices of stocks or surveys (e.g., S&P
Industry Surveys) to evaluate a Fund's historical performance or current or
potential value with respect to the particular industry or sector.

     In addition, the Trust also may use, in advertisements and other types of
literature, information and statements: (1) showing that bank savings accounts
offer a guaranteed return of principal and a fixed rate of interest, but no
opportunity for capital growth; and (2)  describing Wells Fargo Bank, and its
affiliates and predecessors, as one of the first investment managers to advise
investment accounts using asset allocation and index strategies.  The Trust also
may include in advertising and other types of literature information and other
data from reports and studies prepared by the Tax Foundation, including
information regarding federal and state tax levels and the related "Tax Freedom
Day."

     The Trust also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by an NRSRO, such as Standard & Poor's
Corporation.  Such rating would assess the creditworthiness of the investments
held by the Fund.  The assigned rating would not be a recommendation to
purchase, sell or hold the Fund's shares since the rating would not comment on
the market price of the Fund's shares or the suitability of the Fund for a
particular investor.  In addition, the assigned rating would be subject to
change, suspension or withdrawal as a result of changes in, or unavailability
of, information relating to the Fund or its

                                       24
<PAGE>

investments. The Trust may compare the Fund's performance with other investments
which are assigned ratings by NRSROs. Any such comparisons may be useful to
investors who wish to compare the Fund's past performance with other rated
investments.

     From time to time, the Funds may use the following statements, or
variations thereof, in advertisements and other promotional materials:  "Wells
Fargo Bank, as a Shareholder Servicing Agent for the Wells Fargo Funds Trust,
provides various services to its customers that are also shareholders of the
Funds.  These services may include access to Wells Fargo Funds Trust account
information through Automated Teller Machines (ATMs), the placement of purchase
and redemption requests for shares of the Funds through ATMs and the
availability of combined Wells Fargo Bank and Wells Fargo Funds Trust account
statements."

     The Trust also may disclose, in advertising and other types of literature,
information and statements that Wells Capital Management (formerly, Wells Fargo
Investment Management), a division of Wells Fargo Bank, is listed in the top 100
by Institutional Investor magazine in its July 1997 survey "America's Top 300
Money Managers."  This survey ranks money managers in several asset categories.
The Trust may also disclose in advertising and other types of sales literature
the assets and categories of assets under management by the Trust's investment
advisor and the total amount of assets and mutual fund assets managed by Wells
Fargo Bank.  As of August 1, 1998, Wells Fargo Bank and its affiliates provided
investment advisory services for approximately $63 billion of assets of
individual, trusts, estates and institutions and $32 billion of mutual fund
assets.

     The Trust also may discuss in advertising and other types of literature the
features, terms and conditions of Wells Fargo Bank accounts through which
investments in the Funds may be made via a "sweep" arrangement, including,
without limitation, the Managed Sweep Account, Money Market Checking Account and
Money Market Access Account (collectively, the "Sweep Accounts").  Such
advertisements and other literature may include, without limitation, discussions
of such terms and conditions as the minimum deposit required to open a Sweep
Account, a description of the yield earned on shares of the Funds through a
Sweep Account, a description of any monthly or other service charge on a Sweep
Account and any minimum required balance to waive such service charges, any
overdraft protection plan offered in connection with a Sweep Account, a
description of any ATM or check privileges offered in connection with a Sweep
Account and any other terms, conditions, features or plans offered in connection
with a Sweep Account.  Such advertising or other literature may also include a
discussion of the advantages of establishing and maintaining a Sweep Account,
and may include statements from customers as to the reasons why such customers
have established and maintained a Sweep Account.

     The Trust may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels").  Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees.  Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely

                                       25
<PAGE>

through Electronic Channels. Advertising and other literature may disclose that
Wells Fargo Bank may maintain Web sites, pages or other information sites
accessible through Electronic Channels (an "Information Site") and may describe
the contents and features of the Information Site and instruct investors on how
to access the Information Site and open a Sweep Account. Advertising and other
literature may also disclose the procedures employed by Wells Fargo Bank to
secure information provided by investors, including disclosure and discussion of
the tools and services for accessing Electronic Channels. Such advertising or
other literature may include discussions of the advantages of establishing and
maintaining a Sweep Account through Electronic Channels and testimonials from
Wells Fargo Bank customers or employees and may also include descriptions of
locations where product demonstrations may occur. The Trust may also disclose
the ranking of Wells Fargo Bank as one of the largest money managers in the
United States.

                       DETERMINATION OF NET ASSET VALUE

     Net asset value per share for the shares of the Money Market Trust and
Overland Express Sweep Fund is determined as of 12:00 noon (Pacific time)/2:00
p.m. (Central time), and the NAV of the other money market funds is determined
as of 9:00 a.m. (Pacific time)/11:00 a.m. (Central time) on each day such Funds
are open for business.  If the markets for the instruments and securities the
Funds invest in close early, the Funds may close early and may value their
shares at earlier times under these circumstances.  Expenses and fees, including
advisory fees, are accrued daily and are taken into account for the purpose of
determining the net asset value of the Funds' shares.

     Each Fund uses the amortized cost method to determine the value of its
portfolio securities pursuant to Rule 2a-7 under the 1940 Act.  The amortized
cost method involves valuing a security at its cost and amortizing any discount
or premium over the period until maturity, regardless of the impact of
fluctuating interest rates on the market value of the security.  While this
method provides certainty in valuation, it may result in periods during which
the value, as determined by amortized cost, is higher or lower than the price
that the Funds would receive if the security were sold.  During these periods
the yield to a shareholder may differ somewhat from that which could be obtained
from a similar fund that uses a method of valuation based upon market prices.
Thus, during periods of declining interest rates, if the use of the amortized
cost method resulted in a lower value of the Funds' portfolio on a particular
day, a prospective investor in the Funds would be able to obtain a somewhat
higher yield than would result from investment in a fund using solely market
values, and existing Fund shareholders would receive correspondingly less
income.  The converse would apply during periods of rising interest rates.

     Rule 2a-7 provides that in order to value its portfolio using the amortized
cost method, a Fund must maintain a dollar-weighted average portfolio maturity
of 90 days or less, purchase securities having remaining maturities (as defined
in Rule 2a-7) of thirteen months or less and invest only in those high-quality
securities that are determined by the Board of Trustees to present minimal
credit risks.  The maturity of an instrument is generally deemed to be the
period

                                       26
<PAGE>

remaining until the date when the principal amount thereof is due or the date on
which the instrument is to be redeemed. However, Rule 2a-7 provides that the
maturity of an instrument may be deemed shorter in the case of certain
instruments, including certain variable and floating rate instruments subject to
demand features. Pursuant to Rule 2a-7, the Board is required to establish
procedures designed to stabilize, to the extent reasonably possible, a Fund's
price per share as computed for the purpose of sales and redemptions at $1.00.
Such procedures include review of the Fund's portfolio holdings by the Board of
Trustees, at such intervals as it may deem appropriate, to determine whether the
Fund's net asset value calculated by using available market quotations deviates
from $1.00 per share based on amortized cost. The extent of any deviation will
be examined by the Board of Trustees. If such deviation exceeds 1/2 of 1%, the
Board will promptly consider what action, if any, will be initiated. In the
event the Board determines that a deviation exists that may result in material
dilution or other unfair results to investors or existing shareholders, the
Board will take such corrective action as it regards as necessary and
appropriate, including the sale of portfolio instruments prior to maturity to
realize capital gains or losses or to shorten average portfolio maturity,
withholding dividends or establishing a net asset value per share by using
available market quotations. It is the intention of the Funds to maintain a per
share net asset value of $1.00, but there can be no assurance that each Fund
will do so.

     Instruments having variable or floating interest rates or demand features
may be deemed to have remaining maturities as follows: (a) a government security
with a variable rate of interest readjusted no less frequently than every
thirteen months may be deemed to have a maturity equal to the period remaining
until the next readjustment of the interest rate; (b) an instrument with a
variable rate of interest, the principal amount of which is scheduled on the
face of the instrument to be paid in thirteen months or less, may be deemed to
have a maturity equal to the period remaining until the next readjustment of the
interest rate; (c) an instrument with a variable rate of interest that is
subject to a demand feature may be deemed to have a maturity equal to the longer
of the period remaining until the next readjustment of the interest rate or the
period remaining until the principal amount can be recovered through demand; (d)
an instrument with a floating rate of interest that is subject to a demand
feature may be deemed to have a maturity equal to the period remaining until the
principal amount can be recovered through demand; and (e) a repurchase agreement
may be deemed to have a maturity equal to the period remaining until the date on
which the repurchase of the underlying securities is scheduled to occur or,
where no date is specified but the agreement is subject to demand, the notice
period applicable to a demand for the repurchase of the securities.


                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

     Shares of the Funds may be purchased on any day the Funds are open for
business (a "Business Day").  The Funds are open on any day Wells Fargo Bank is
open.  Wells Fargo Bank is open Monday through Friday and is closed on federal
bank holidays.  Currently, those holidays are New Year's Day, President's Day,
Martin Luther King Jr. Day, Memorial Day, Independence Day, Labor Day, Columbus
Day, Veterans Day, Thanksgiving Day and Christmas Day.

                                       27
<PAGE>

     Purchase orders for a Fund received before such Fund's NAV calculation time
generally are processed at such time on that Business Day. Purchase Orders
received after a Fund's NAV calculation time generally are processed at such
Fund's NAV calculation time on the next Business Day. Selling Agents may
establish earlier cut-off times for processing your order. Requests received by
a Selling Agent after the applicable cut-off time will be processed on the next
Business Day. On any day the trading markets for both U.S. government securities
and money market instruments close early, the Funds will close early. On these
days, the net asset value calculation time and the dividend, purchase and
redemption cut-off times for the Funds may be earlier than 12:00 Noon.

     Payment for shares may, in the discretion of the Advisor, be made in the
form of securities that are permissible investments for the Funds. For further
information about this form of payment please contact Stephens. In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that such Fund receives satisfactory
assurances that (i) it will have good and marketable title to the securities
received by it; (ii) that the securities are in proper form for transfer to the
Fund; and (iii) adequate information will be provided concerning the basis and
other matters relating to the securities.

     Under the 1940 Act, the Funds may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary weekend and holiday closings, or during
which trading is restricted, or during which as determined by the SEC by rule or
regulation) an emergency exists as a result of which disposal or valuation of
portfolio securities is not reasonably practicable, or for such periods as the
SEC may permit. The Trust may also redeem shares involuntarily or make payment
for redemption in securities or other property if it appears appropriate to do
so in light of the Company's responsibilities under the 1940 Act. In addition,
the Trust may redeem shares involuntarily to reimburse the Funds for any losses
sustained by reason of the failure of a shareholders to make full payment for
shares purchased or to collect any charge relating to a transaction effected for
the benefit of a shareholder which is applicable to shares of a Fund.

                            PORTFOLIO TRANSACTIONS

     The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities. Subject to policies
established by the Trust's Board of Trustees, Wells Fargo Bank is responsible
for each Fund's portfolio decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Trust to obtain the best results
taking into account the dealer's general execution and operational facilities,
the type of transaction involved and other factors such as the dealer's risk in
positioning the securities involved. While Wells Fargo Bank generally seeks
reasonably competitive spreads or commissions, the Funds will not necessarily be
paying the lowest spread or commission available.

                                       28
<PAGE>

     Purchases and sales of non-equity securities usually will be principal
transactions. Portfolio securities normally will be purchased or sold from or to
dealers serving as market makers for the securities at a net price. Each of the
Funds also will purchase portfolio securities in underwritten offerings and may
purchase securities directly from the issuer. Generally, municipal obligations
and taxable money market securities are traded on a net basis and do not involve
brokerage commissions. The cost of executing a Fund's portfolio securities
transactions will consist primarily of dealer spreads and underwriting
commissions. Under the 1940 Act, persons affiliated with the Trust are
prohibited from dealing with the Trust as a principal in the purchase and sale
of securities unless an exemptive order allowing such transactions is obtained
from the SEC or an exemption is otherwise available. The Funds may purchase
securities from underwriting syndicates of which Stephens or Wells Fargo Bank is
a member under certain conditions in accordance with the provisions of a rule
adopted under the 1940 Act and in compliance with procedures adopted by the
Board of Trustees.

     Wells Fargo Bank, as the Investment Advisor of each of the Funds, may, in
circumstances in which two or more dealers are in a position to offer comparable
results for a Fund portfolio transaction, give preference to a dealer that has
provided statistical or other research services to Wells Fargo Bank. By
allocating transactions in this manner, Wells Fargo Bank is able to supplement
its research and analysis with the views and information of securities firms.
Information so received will be in addition to, and not in lieu of, the services
required to be performed by Wells Fargo Bank under the Advisory Contracts, and
the expenses of Wells Fargo Bank will not necessarily be reduced as a result of
the receipt of this supplemental research information. Furthermore, research
services furnished by dealers through which Wells Fargo Bank places securities
transactions for a Fund may be used by Wells Fargo Bank in servicing its other
accounts, and not all of these services may be used by Wells Fargo Bank in
connection with advising the Funds.

     Portfolio Turnover. The portfolio turnover rate is not a limiting factor
     ------------------
when Wells Fargo Bank deems portfolio changes appropriate. Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the best interests of the
Funds and their shareholders. The portfolio turnover rate is calculated by
dividing the lesser of purchases or sales of portfolio securities by the average
monthly value of the Fund's portfolio securities. For purposes of this
calculation, portfolio securities exclude all securities having a maturity when
purchased of one year or less. Portfolio turnover generally involves some
expenses to the Funds, including brokerage commissions or dealer mark-ups and
other transaction costs on the sale of securities and the reinvestment in other
securities. Portfolio turnover also can generate short-term capital gain tax
consequences. Portfolio turnover rate is not a limiting factor when Wells Fargo
Bank deems portfolio changes appropriate.

                                 FUND EXPENSES

     From time to time, Wells Fargo Bank may waive fees from the Funds in whole
or in part. Any such waiver will reduce expenses and, accordingly, have a
favorable impact on a Fund's performance. Except for the expenses borne by Wells
Fargo Bank, the Trust bears all costs of its

                                       29
<PAGE>

operations, including the compensation of its Trustees who are not affiliated
with Wells Fargo Bank or any of their affiliates; advisory, shareholder
servicing and administration fees; payments pursuant to any Plan; interest
charges; taxes; fees and expenses of its independent auditors, legal counsel,
transfer agent and dividend disbursing agent; expenses of redeeming shares;
expenses of preparing and printing prospectuses (except the expense of printing
and mailing prospectuses used for promotional purposes, unless otherwise payable
pursuant to a Plan), shareholders' reports, notices, proxy statements and
reports to regulatory agencies; insurance premiums and certain expenses relating
to insurance coverage; trade association membership dues; brokerage and other
expenses connected with the execution of portfolio transactions; fees and
expenses of its custodian, including those for keeping books and accounts and
calculating the net asset value per share of a Fund; expenses of shareholders'
meetings; expenses relating to the issuance, registration and qualification of a
Fund's shares; pricing services, and any extraordinary expenses. Expenses
attributable to a Fund are charged against a Fund assets. General expenses of
the Trust are allocated among all of the funds of the Trust, including a Fund,
in a manner proportionate to the net assets of each Fund, on a transactional
basis, or on such other basis as the Trust's Board of Trustees deems equitable.

                             FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes." The Prospectuses of each Fund
describe generally the tax treatment of distributions by the Funds. This section
of the SAI includes additional information concerning Federal income taxes.

     General. The Company intends to qualify each Fund as a regulated
     -------
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"), as long as such qualification is in the best interest of
the Fund's shareholders. Each Fund will be treated as a separate entity for
Federal income tax purposes. Thus, the provisions of the Code applicable to
regulated investment companies generally will be applied to each Fund, rather
than to the Company as a whole. In addition, net capital gains, net investment
income, and operating expenses will be determined separately for each Fund. As a
regulated investment company, each Fund will not be taxed on its net investment
income and capital gains distributed to its shareholders.

     Qualification as a regulated investment company under the Code requires,
among other things, that each Fund (a) derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including, but not limited to, gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) diversify its holdings so that,
at the end of each quarter of the taxable year, (i) at least 50% of the market
value of the Fund's assets is represented by cash, government securities and
other securities limited in respect of any one issuer to an amount not greater
than 5% of the Fund's assets and 10% of the outstanding voting securities of
such issuer, and (ii) not more than 25% of the value

                                       30
<PAGE>

of its assets is invested in the securities of any one issuer (other than U.S.
Government obligations and the securities of other regulated investment
companies), or in two or more issuers which the Fund controls and which are
determined to be engaged in the same or similar trades or businesses.

     The Funds also must distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income (which, for this
purpose, includes net short-term capital gains) earned in each taxable year. In
general, these distributions must actually or be deemed to be made in the
taxable year. However, in certain circumstances, such distributions may be made
in the 12 months following the taxable year. Furthermore, distributions declared
in October, November or December of one taxable year and paid by January 31 of
the following taxable year will be treated as paid by December 31 of the first
taxable year. The Funds intend to pay out substantially all of their net
investment income and net realized capital gains (if any) for each year.

     In addition, a regulated investment company must, in general, derive less
than 30% of its gross income from the sale or other disposition of securities or
options thereon held for less than three months. However, this restriction has
been repealed with respect to a regulated investment company's taxable years
beginning after August 5, 1997.

     Excise Tax. A 4% nondeductible excise tax will be imposed on each Fund
     ----------
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year. Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

     Taxation of Fund Investments. Except as provided herein, gains and losses
     ----------------------------
on the sale of portfolio securities by a Fund will generally be capital gains
and losses. Such gains and losses will ordinarily be long-term capital gains and
losses if the securities have been held by the Fund for more than one year at
the time of disposition of the securities.

     Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by the Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

     If a Fund enters into a "constructive sale" of any appreciated position in
stock, a partnership interest, or certain debt instruments, the Fund must
recognize gain (but not loss) with respect to that position. For this purpose, a
constructive sale occurs when the Fund enters into one of the following
transactions with respect to the same or substantially identical property: (i) a
short sale; (ii) an offsetting notional principal contract; or (iii) a futures
or forward contract.

     Capital Gain Distributions. Distributions which are designated by a Fund
     --------------------------
as capital gain distributions will be taxed to shareholders as long-term term
capital gain (to the extent such dividends do exceed the Fund's actual net
capital gains for the taxable year), regardless of how

                                       31
<PAGE>

long a shareholder has held Fund shares. Such distributions will be designated
as capital gain distributions in a written notice mailed by the Fund to its
shareholders not later than 60 days after the close of the Fund's taxable year.

     Other Distributions. For Federal income tax purposes, a Fund's earnings
     -------------------
and profits will be determined at the end of each taxable year and will be
allocated pro rata over the entire year. For Federal income tax purposes, only
amounts paid out of earnings and profits will qualify as dividends. Thus, if
during a taxable year a Fund's declared dividends (as declared daily throughout
the year) exceed the Fund's net income (as determined at the end of the year),
only that portion of the year's distributions which equals the year's earnings
and profits will be deemed to have constituted a dividend. It is expected that
each Fund's net income, on an annual basis, will equal the dividends declared
during the year.

     Disposition of Fund Shares. A disposition of Fund shares pursuant to a
     --------------------------
redemption (including a redemption in-kind) or an exchange will ordinarily
result in a taxable capital gain or loss, depending on the amount received for
the shares (or are deemed to be received in the case of an exchange) and the
cost of the shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred in acquiring the Fund's shares shall not be
taken into account (to the extent such previous sales charges do not exceed the
reduction in sales charges on the new purchase) for the purpose of determining
the amount of gain or loss on the disposition, but will be treated as having
been incurred in the acquisition of such other shares. Also, any loss realized
on a redemption or exchange of shares of the Fund will be disallowed to the
extent that substantially identical shares are acquired within the 61-day period
beginning 30 days before and ending 30 days after the shares are disposed of.

     If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as a long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as a long-term capital loss to the extent of the designated capital gain
distribution. In addition, if a shareholder holds Fund shares for six months or
less, any loss on the sale or exchange of those shares will be disallowed to the
extent of the amount of exempt-interest dividends received with respect to the
shares. The Treasury Department is authorized to issue regulations reducing the
six months holding requirement to a period of not less than the greater of 31
days or the period between regular dividend distributions where a Fund regularly
distributes at least 90% of its net tax-exempt interest, if any. No such
regulations have been issued as of the date of this SAI. The loss disallowance
rules described in this paragraph do not apply to losses realized under a
periodic redemption plan.

     Federal Income Tax Rates. As of the printing of this SAI, the maximum
     ------------------------
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum

                                       32
<PAGE>

individual marginal tax rate applicable to net capital gain is 20%; and the
maximum corporate tax rate applicable to ordinary income and net capital gain is
35% (marginal tax rates may be higher for some corporations to reduce or
eliminate the benefit of lower marginal income tax rates). Naturally, the amount
of tax payable by an individual or corporation will be affected by a combination
of tax laws covering, for example, deductions, credits, deferrals, exemptions,
sources of income and other matters.

     Backup Withholding. The Company may be required to withhold, subject to
     ------------------
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, unless the shareholder certifies that the Taxpayer Identification
Number ("TIN") provided is correct and that the shareholder is not subject to
backup withholding, or the IRS notifies the Company that the shareholder's TIN
is incorrect or that the shareholder is subject to backup withholding. Such tax
withheld does not constitute any additional tax imposed on the shareholder, and
may be claimed as a tax payment on the shareholder's Federal income tax return.
An investor must provide a valid TIN upon opening or reopening an account.
Failure to furnish a valid TIN to the Company also could subject the investor to
penalties imposed by the IRS.

     Foreign Shareholders. Under the Code, distributions of net investment
     --------------------
income by the Funds to a nonresident alien individual, foreign trust (i.e.,
trust which a U.S. court is able to exercise primary supervision over
administration of that trust and one or more U.S. persons have authority to
control substantial decisions of that trust), foreign estate (i.e., the income
of which is not subject to U.S. tax regardless of source), foreign corporation,
or foreign partnership (a "foreign shareholder") will be subject to U.S.
withholding tax (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend paid by the Fund to a foreign
shareholder is "effectively connected" with a U.S. trade or business (or, if an
income tax treaty applies, is attributable to a U.S. permanent establishment of
the foreign shareholder), in which case the reporting and withholding
requirements applicable to U.S. persons will apply. Distributions of capital
gains are generally not subject to tax withholding.

     New Regulations. On October 6, 1997, the Treasury Department issued new
     ---------------
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders. The New Regulations will generally be
effective for payments made after December 31, 1999, subject to certain
transition rules. Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders that will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax advisors regarding the
New Regulations.

     Tax-Deferred Plans. The shares of the Funds are available for a variety of
     ------------------
tax-deferred retirement and other plans, including Individual Retirement
Accounts ("IRA"), Simplified Employee Pension Plans ("SEP-IRA"), Savings
Incentive Match Plans for Employees ("SIMPLE

                                       33
<PAGE>

plans"), Roth IRAs, and Education IRAs, which permit investors to defer some of
their income from taxes. Investors should contact their selling agents for
details concerning retirement plans.

                                 CAPITAL STOCK

     The Funds are nine of the funds in the Wells Fargo Funds Trust family of
funds. The Trust was organized as a Delaware business trust on March 10, 1999.

     Most of the Trust's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors. Certain of the Trust's funds also are authorized to issue
other classes of shares, which are sold primarily to institutional investors.
Each class of shares in a fund represents an equal, proportionate interest in a
fund with other shares of the same class. Shareholders of each class bear their
pro rata portion of the fund's operating expenses, except for certain class-
specific expenses (e.g., any state securities registration fees, shareholder
servicing fees or distribution fees that may be paid under Rule 12b-1) that are
allocated to a particular class. Please contact Investor Services at 1-800-222-
8222 if you would like additional information about other funds or classes of
shares offered.

     With respect to matters that affect one class but not another, shareholders
vote as a class; for example, the approval of a Plan. Subject to the foregoing,
all shares of a Fund have equal voting rights and will be voted in the
aggregate, and not by series, except where voting by a series is required by law
or where the matter involved only affects one series. For example, a change in a
Fund's fundamental investment policy affects only one Series and would be voted
upon only by shareholders of the Fund involved. Additionally, approval of an
advisory contract since it affects only one Fund, is a matter to be determined
separately by each Series. Approval by the shareholders of one Series is
effective as to that Series whether or not sufficient votes are received from
the shareholders of the other Series to approve the proposal as to those Series.

     As used in the Prospectus and in this SAI, the term "majority" when
referring to approvals to be obtained from shareholders of a Class of a Fund,
means the vote of the lesser of (i) 67% of the shares of such class of the Fund
represented at a meeting if the holders of more than 50% of the outstanding
shares of such Class Fund are present in person or by proxy, or (ii) more than
50% of the outstanding shares of such Class of the Fund. The term "majority,"
when referring to the approvals to be obtained from shareholders of the Trust as
a whole, means the vote of the lesser of (i) 67% of the Trust's shares
represented at a meeting if the holders of more than 50% of the Trust's
outstanding shares are present in person or by proxy, or (ii) more than 50% of
the Trust's outstanding shares.

     Shareholders are entitled to one vote for each full share held and
fractional votes for fractional shares held. Shareholders are not entitled to
any preemptive rights. All shares, when issued, will be fully paid and non-
assessable by the Trust.

     The Trust may dispense with an annual meeting of shareholders in any year
in which it is not required to elect directors under the 1940 Act.

                                       34
<PAGE>

     Each share of a class of a Fund represents an equal proportional interest
in the Fund with each other share in the same class and is entitled to such
dividends and distributions out of the income earned on the assets belonging to
the Fund as are declared in the discretion of the Trustees. In the event of the
liquidation or dissolution of the Trust, shareholders of a Fund or class are
entitled to receive the assets attributable to the Fund or class that are
available for distribution, and a distribution of any general assets not
attributable to a particular investment portfolio that are available for
distribution in such manner and on such basis as the Trustees in their sole
discretion may determine.

     Set forth below [as of March 25, 1999,] is the name, address and share
ownership of each person known by the Trust to have beneficial or record
ownership of 5% or more of a class of each Fund or 5% or more of the voting
securities of each Fund as a whole. The term "N/A" is used where a shareholder
holds 5% or more of a class, but less than 5% of a Fund as a whole.

                                 5% OWNERSHIP

     For purposes of the 1940 Act, any person who owns directly or through one
or more controlled companies more than 25% of the voting securities of a company
is presumed to "control" such company. Accordingly, to the extent that a
shareholder identified in the foregoing table is identified as the beneficial
holder of more than 25% of a class (or Fund) or is identified as the holder of
record or more than 25% of a class (or Fund) and has voting and/or investment

                                   APPENDIX

       The following is a description of the ratings given by Moody's and S&P to
corporate and municipal bonds, municipal notes, and corporate and municipal
commercial paper.

Corporate and Municipal Bonds
- -----------------------------

       Moody's: The four highest ratings for corporate and municipal bonds are
       -------
"Aaa," "Aa," "A" and "Baa." Bonds rated "Aaa" are judged to be of the "best
quality" and carry the smallest amount of investment risk. Bonds rated "Aa" are
of "high quality by all standards," but margins of protection or other elements
make long-term risks appear somewhat greater than "Aaa" rated bonds. Bonds rated
"A" possess many favorable investment attributes and are considered to be upper
medium grade obligations. Bonds rated "Baa" are considered to be medium grade
obligations; 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 have
speculative characteristics as well. Moody's applies numerical modifiers: 1, 2
and 3 in each rating category from "Aa" through "Baa" in its rating system. The
modifier 1 indicates that the security ranks in the higher end of its category;
the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that
the issue ranks in the lower end.

       S&P: The four highest ratings for corporate and municipal bonds are
       ---
"AAA," "AA," "A" and "BBB." Bonds rated "AAA" have the highest ratings assigned
by S&P and have an extremely strong capacity to pay interest and repay
principal. Bonds rated "AA" have a "very strong capacity to pay interest and
repay principal" and differ "from the highest rated issued only in small
degree." Bonds rated "A" have a "strong capacity" to pay interest and repay
principal, but are "somewhat more susceptible" to adverse effects of changes in
economic conditions or other circumstances than bonds in higher rated
categories. Bonds rated "BBB" are regarded as having an "adequate capacity" to
pay interest and repay principal, but changes in economic conditions or other
circumstances are more likely to lead to a "weakened capacity" to make such
repayments. The ratings from "AA" to "BBB" may be modified by the addition of a
plus or minus sign to show relative standing within the category.

Municipal Notes
- ---------------

       Moody's: The highest ratings for state and municipal short-term
       -------
obligations are "MIG 1," "MIG 2," and "MIG 3" (or "VMIG 1," "VMIG 2" and "VMIG
3" in the case of an issue having a variable rate demand feature). Notes rated
"MIG 1" or "VMIG 1" are judged to be of the "best quality." Notes rated "MIG 2"
or "VMIG 2" are of "high quality," with margins of protections "ample although
not as large as in the preceding group." Notes rated "MIG 3" or "VMIG 3" are of
"favorable quality," with all security elements accounted for, but lacking the
strength of the preceding grades.

                                      A-1
<PAGE>

       S&P: The "SP-1" rating reflects a "very strong or strong capacity to pay
       ---
principal and interest." Notes issued with "overwhelming safety characteristics"
will be rated "SP-1+." The "SP-2" rating reflects a "satisfactory capacity" to
pay principal and interest.

Corporate and Municipal Commercial Paper
- ----------------------------------------

       Moody's: The highest rating for corporate and municipal commercial paper
       -------
is "P-1" (Prime-1). Issuers rated "P-1" have a "superior capacity for repayment
of short-term promissory obligations." Issuers rated "P-2" (Prime-2) "have a
strong capacity for repayment of short-term promissory obligations," but
earnings trends, while sound, will be subject to more variation.

       S&P: The "A-1" rating for corporate and municipal commercial paper
       ---
indicates that the "degree of safety regarding timely payment is either
overwhelming or very strong." Commercial paper with "overwhelming safety
characteristics" will be rated "A-1+." Commercial paper with a strong capacity
for timely payments on issues will be rated "A-2."

Corporate Notes
- ---------------

       S&P: The two highest ratings for corporate notes are "SP-1" and "SP-2."
       ---
The "SP-1" rating reflects a "very strong or strong capacity to pay principal
and interest." Notes issued with "overwhelming safety characteristics" will be
rated "SP-1+." The "SP-2" rating reflects a "satisfactory capacity" to pay
principal and interest.

SUMMARY OF IMPORTANT RISKS

This section summarizes important risks that are common to all of the Portfolios
described in this Prospectus, and important risks that relate specifically to
particular Portfolios. Both are important to your investment choice. Additional
information about these and other risks is included in the individual Portfolio
descriptions later in this Prospectus and under General Investment Risks
beginning on page __ and in the Portfolios' Statement of Additional Information.
An investment in a Portfolio is not a deposit of Wells Fargo Bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

The risks associated with each Portfolio is the risk related to each underlying
investment company (the "Underlying Fund") in which the Portfolio invests. Thus,
the indirect risks of the Portfolios are the direct risks for the Underlying
Funds, which will be discussed in this Prospectus. References in this Prospectus
to the investment activities of the Portfolios also refers to the Underlying
Funds in which it invests.

COMMON RISKS FOR THE PORTFOLIOS

The Portfolios seek to reduce the risk of your investment by diversifying among
different asset classes of stock, bond, and money market instruments and among
different fund managers. Investing in a mutual fund that holds a diversified
portfolio of other mutual funds provides a wider range of investment management
talent and investment diversification than is available in a single mutual fund.
The Portfolios are each designed to provide you with a single investment that
offers diverse asset classes, fund management, and fund categories. You still
have, however, the risks of investing in various asset classes, such as market
risks related to stocks and bonds as well as the risk of investing in a
particular Underlying Fund, such as risks related to the particular investment
management style.

Investments in a Portfolio may result in your incurring greater expenses than
if you were to invest directly in the Underlying Funds in which the Portfolio
invests.

PORTFOLIO-SPECIFIC RISKS

The Portfolios invest in the Underlying Funds which in turn invest in equity
securities, which are subject to equity market risk. This is the risk that stock
prices will fluctuate and can decline and reduce the value of a Fund's
portfolio. Certain types of stock and certain individual stocks selected for an
Underlying Fund's portfolio may underperform or decline in value more than the
overall market. As of the date of this Prospectus, the equity markets, as
measured by the S&P 500 Index and other commonly used indexes, are trading at or
close to record levels. There can be no guarantee that these levels will
continue. The Underlying Funds that invest in smaller companies, in foreign
companies (including investments made through American Depositary Receipts and
similar instruments), and in emerging markets are subject to additional risks,
including less liquidity and greater price volatility. An Underlying Fund's
investments in foreign companies and emerging markets are also subject to
special risks associated with international investing, including currency,
political, regulatory and diplomatic risks.

The Portfolios invest in the Underlying Funds which in turn invest some of their
assets in debt securities, such as notes and bonds, which are subject to credit
risk and interest rate risk. Credit risk is the possibility that an issuer of an
instrument will be unable to make interest payments or repay principal. Changes
in the financial strength of an issuer or changes in the credit rating of a
security may affect its value. Interest rate risk is the risk that interest
rates may increase, which will reduce the resale value of securities in a
Underlying Fund's investments, including U.S. Government obligations. Debt
securities with longer maturities are generally more sensitive to interest rate
changes than those with shorter maturities. Changes in market interest rates do
not affect the rate payable on debt securities held in a Underlying Fund, unless
the have adjustable or variable rate features, which can reduce interest rate
risk.

                                       5
<PAGE>

Changes in market interest rates may also extend or shorten the duration of
certain types of instruments, such as asset-backed securities, and affect their
value and the return on your investment. The Underlying Funds may invest some of
their assets in debt securities.

PERFORMANCE HISTORY

The Portfolios in this prospectus will commence operations in September 1999.
No performance information is given for the Portfolios because they will have
been in operation for less than one year.

WEALTHBUILDER GROWTH PORTFOLIO

INVESTMENT OBJECTIVE
WealthBuilder Growth Portfolio seeks capital appreciation.

INVESTMENT POLICIES
The Portfolio seeks to meet its investment objective by allocating among stock
funds and money market funds.  Certain research indicates that the greatest
impact on investment returns may be due to the asset allocation decision (the
mix of stocks, bonds and cash-equivalents) rather than market timing or the
selection of individual stocks and bonds.

The Portfolio allocates its investments among stock funds and money market funds
by investing in a combination of different types.  The Portfolio, in accordance
with its investment objective, will change its allocations between types of
funds depending on changing market conditions and the risk/return
characteristics of the asset classes.  The amount the Portfolio has invested in
stock and money market funds at any particular time may vary due to market
conditions or other factors.  The investment advisor rebalances a Portfolio when
the Portfolio's asset allocation deviates by five percent from the target
allocation.

PERMITTED INVESTMENTS
Under normal market conditions, we invest:

 .     from 97% to 100% of our assets in stock funds; and

 .     from 0% to 3% of our assets in money market funds.

IMPORTANT RISK FACTORS
You should consider both the General Investment Risks and the risks related to
the Underlying Funds and the specific risks listed on page ___.  They are
equally important to your investment choice.

PORTFOLIO MANAGER
Galen Blomster, Ph.D., CFA, Vice President & Director of Research is primarily
responsible for day-to-day management and allocation services and has been since
the inception of the Portfolio.  Mr. Blomster has been employed by Norwest since
1977.  In addition to the responsibilities for the Portfolios, the portfolio
manager may perform portfolio management and other duties for other Funds of the
Trust.

THE UNDERLYING FUNDS

The Portfolios normally invest in open-end management investment companies or
series thereof as listed below.  The Portfolios may also invest in closed-end
management investment companies and/or unit investment trusts.  All of these
investments are referred to as the Underlying Funds.  Each Portfolio may hold
certain securities directly.

     (1) STOCK FUNDS.  Stock funds invest primarily in domestic or foreign
         common stocks or securities convertible into or exchangeable for
         common stock. The Underlying Funds may include stock funds holding
         large company stocks, small company stocks, and international stocks.

     (2) BOND FUNDS.  Bond funds invest primarily in debt securities issued by
         companies, municipalities, governments, or government agencies. The
         issuer of a bond is required to pay the bond holder the amount of the
         loan (or par value) at a specified maturity and to make scheduled
         interest payments. Only the WealthBuilder Growth Balanced Portfolio
         invests in bond funds.

     (3) MONEY MARKET FUNDS.  Money market funds invest in U.S.-dollar
         denominated short-term money market instruments determined to present
         minimal credit risk. Under normal circumstances, the Portfolios may
         invest in affiliated Underlying Funds that are money market funds. The
         Portfolios may also invest directly in money market instruments, which
         include commercial paper and time deposits issued by large banks,
         repurchase agreements, and U.S. Government Securities.

The risks associated with each Portfolio is the risk related to each Underlying
Fund in which the Portfolio invests, which risk passes-through to the
Portfolios.  Thus, the indirect risks of the Portfolios are the direct risks for
the Underlying Funds, as discussed below.

IMPORTANT RISK FACTORS FOR THE UNDERLYING FUNDS

The Portfolios invest in money market funds.  Although money market funds seek
to maintain a $1.00 per share net asset value, there is no guarantee that they
will be able to do so.  Generally, short-term funds do not earn as high a level
of income as funds that invest in longer-term instruments.  Securities of U.S.
branches of foreign banks and foreign branches of U.S. banks are subject to
additional risks, such as political turmoil, the imposition of foreign
withholding taxes, and the establishment of exchange controls or the adoption of
other foreign governmental restrictions that may affect the payment of principal
and/or interest on these securities.

Foreign obligations may entail additional risks, such as currency, political,
regulatory and diplomatic risks, which are described in more detail in the
General Investment Risks section below.  The value of investments in options on
stock indexes and stock index futures is affected by price movements for the
stocks in a particular index, rather than price movements for an individual
security.

The Underlying Funds are primarily subject to the equity securities and debt
securities risks described in the Summary of Important Risks section.

Mortgage- and asset-backed securities may not be guaranteed by the U.S.
Treasury.  Mortgage-backed securities are subject to prepayment risk, which can
reduce the rate of return on such securities.  The Underlying Funds may invest
in lower-rated securities, which tend to be more sensitive to economic
conditions and involve greater credit risk than higher-rated securities.

Municipal obligations rely on the creditworthiness or revenue production of
their issuers.  Municipal obligations may be difficult to obtain because of
reduced supply, therefore increasing the cost of such securities and effectively
reducing yields to the portfolio.

                                       13
<PAGE>

Investing in shares of other money market funds with substantially similar
objectives and investment policies will subject the Portfolios to the fees
charged by the Underlying Funds, which will reduce returns from these
investments.

Shares of a closed-end investment company may, and typically do, trade at a
discount to net asset value.  In addition, there may be no readily available
market for closed-end investment company shares, in which case the shares are
generally considered illiquid.

You should consider the Common Risks on page __, the General Investment Risks
beginning on page __, and the specific risks listed above.  They are all
important to your investment choice.

GENERAL INVESTMENT RISKS

Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your risk tolerance and preferences.
You should carefully consider the risks common to investing in all mutual funds,
including the Wells Fargo Funds Trust Funds.  Certain common risks are
identified in the Summary of Important Risks on page ___.  Other risks of mutual
fund investing include the following:

 .    Unlike bank deposits, such as CDs or savings accounts, mutual funds are not
     insured by the FDIC.

 .    We cannot guarantee that we will meet our investment objectives.

 .    We do not guarantee the performance of a Portfolio, nor can we assure you
     that the market value of your investment will not decline. We will not
     "make good" any investment loss you may suffer, nor can anyone we contract
     with to provide certain services, such as selling agents or investment
     advisors, offer or promise to make good any such losses.

 .    Share prices--and therefore the value of your investment--will increase
     and decrease with changes in the value of the underlying securities and
     other investments. This is referred to as price volatility.

 .    Investing in any mutual fund, including those deemed conservative, involves
     risk, including the possible loss of any money you invest.

 .    An investment in a single Portfolio, by itself, does not constitute a
     complete investment plan.

 .    Each Underlying Fund may continue to hold debt-instruments that cease to be
     rated by a nationally recognized rating organization or whose ratings fall
     below the levels generally permitted for such Portfolio, provided Wells
     Fargo deems the instrument to be of comparable quality to rated or higher-
     rated instruments. Unrated or downgraded instruments may be more
     susceptible to credit and interest rate risks than investment grade bonds.

 .    The Portfolios may invest a portion of their assets in U.S. Government
     obligations such as securities issued or guaranteed by the Government
     National Mortgage Association ("GNMAs"), the Federal National Mortgage
     Association ("FNMAs") and the Federal Home Loan Mortgage Corporation
     ("FHLMCs"). Each are mortgage-backed securities representing partial
     ownership of a pool of residential mortgage loans. A "pool" or group of
     such mortgages is assembled and, after being approved by the issuing or
     guaranteeing entity, is offered to investors through securities dealers.
     Mortgage-backed securities are subject to prepayment and extension risk,
     which can alter the maturity of the securities and also reduce the rate of
     return on the portfolio. Collateralized mortgage obligations ("CMOs")
     typically represent principal-only and interest-only portions of such
     securities and are subject to increased interest-rate and credit risk. It
     is important to recognize that the U.S. Government does not guarantee the
     market value or current yield of those obligations. Not all U.S. Government
     obligations are backed by the full faith and credit of the U.S. Treasury,
     and the U.S. Government's guarantee does not extend to the Portfolios
     themselves.

 .    The Underlying Fund may also use certain derivative instruments, such as
     options or futures contracts. The term "derivatives" covers a wide number
     of investments, but in general it refers to any financial instrument whose
     value is derived, at least in part, from the price of another security or a
     specified index, asset or rate. Some derivatives may be more sensitive to
     interest rate changes or market moves, and some may be susceptible to
     changes in yields or values due to their structure or contract terms.

 .    The Portfolios may temporarily hold assets in cash or in money market
     instruments, including U.S. Government obligations, shares of other mutual
     funds and repurchase agreements, or make other short-term investments,
     either to maintain liquidity or for short-term defensive purposes when we
     believe it is in the best interests of shareholders to do so. To the extend
     a Portfolio's assets are so invested, they may cause a Portfolio not to
     achieve its investment objective. This practice is expected to have
     limited, if any, effect on the Portfolio's pursuit of their objectives over
     the long term.

GENERAL INVESTMENT RISKS (CONT'D)

 .    The market value of lower-rated debt securities and unrated securities of
     comparable quality that the Underlying Funds may invest in tends to reflect
     individual developments affecting the issuer to a greater extent than the
     market value of higher-related securities, which react primarily to
     fluctuations in the general level of interest rates. Lower-rated securities
     also tend to be more sensitive to economic conditions than higher-rated
     securities. These lower-rated debt securities are considered by nationally
     reorganized rating organizations, on balance, to be predominantly
     speculative with respect to the issuer's capacity to pay interest and repay
     principal. These securities generally involve more credit risk than
     securities in higher-rating categories. Even securities rated "BBB" by S&P
     or by Moody's ratings which are considered investment-grade, possess some
     speculative characteristics.

Investment practices and risk levels are carefully monitored.  Every attempt is
made to ensure that the risk exposure for each Portfolio remains within the
parameters of its objective.

What follows is a general list of the types of risks (some of which are
described above) that may apply to a given Portfolio (and its Underlying Funds)
and a table showing some of the additional investment practices that each
Portfolio may use and the risks associated with them.  Additional information
about these practices is available in the Statement of Additional Information.

COUNTER-PARTY RISK--The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.

CREDIT RISK--The risk that the issuer of a debt security will be unable to make
interest payments or repay principal on schedule.  If an issuer does default,
the affected security could lose all of its value, or be renegotiated at a lower
interest rate or principal amount.  Affected securities might also lose
liquidity.  Credit risk also includes the risk that a party in a transaction may
not be able to complete the transaction as agreed.

CURRENCY RISK--The risk that a change in the exchange rate between U.S. dollars
and a foreign currency may reduce the value of an investment made in a security
denominated in that foreign currency.

DIPLOMATIC RISK--The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value of
liquidity of investments in either country.

EXPERIENCE RISK--The risk presented by a new or innovative security.  The risk
is that insufficient experience exists to forecast how the security's value
might be affected by various economic conditions:

INFORMATION RISK--The risk that information about a security is either
unavailable, incomplete or is inaccurate.

INTEREST RATE RISK--The risk that changes in interest rates can reduce the value
of an existing security.  Generally, when interest rates increase, the value of
a debt security decreases.  The effect is usually more pronounced for securities
with longer maturities.

LEVERAGE RISK--The risk that an investment practice, such as lending portfolio
securities, may increase a Fund's exposure to market risk, interest rate risk or
other risks by, in effect, increasing assets available for investment.

LIQUIDITY RISK--The risk that a security cannot be sold, or cannot be sold
without adversely affecting the price.

MARKET RISK--The risk that the value of a stock, bond or other security will be
reduced by market activity.  This is a basic risk associated with all
securities.

                                       16
<PAGE>

GENERAL INVESTMENT RISKS (CONT'D)

POLITICAL RISK--The risk that political actions, events or instability may be
unfavorable for investments made in a particular nation's or region's industry,
government or markets.

PREPAYMENT RISK--The risk that consumers will pre-pay mortgage loans, which can
alter the maturity of a mortgage-backed security, increase interest-rate risk,
and reduce rates of return.

REGULATORY RISK--The risk that changes in government regulations will adversely
affect the value of a security.  Also the risk that an insufficiently regulated
market might permit inappropriate trading practices.

YEAR 2000 RISK--The Portfolios' principal service providers have advised the
Portfolios that they are working on the necessary changes to their computer
systems to avoid any system failure based on an inability to distinguish the
year 2000 from the year 1900, and that they expect their systems to be adapted
in time.  There can, of course, be no assurance of success.  In addition, the
companies or entities in which the Underlying Funds invest also could be
adversely impacted by the Year 2000 issue.  The extent of such impact cannot be
predicted.

INVESTMENT PRACTICE/RISK

The following table lists some of the additional investment practices of the
Portfolios, including some not disclosed in the Investment Objective and
Investment Policies sections of the Prospectus.  The risks indicated after the
description of the practice are NOT the only potential risks associated with
that practice, but are among the more prominent.  Market risk is assumed for
each.  See the Investment Objective and Investment Policies for each Portfolio
or the Statement of Additional Information for more information on these
practices.

THESE INVESTMENT PRACTICES AND RISKS ARE COMMON TO ALL THE PORTFOLIOS AND
UNDERLYING FUNDS:

ORGANIZATION AND MANAGEMENT OF THE PORTFOLIOS

A number of different entities provide services to the Portfolios.  This section
shows how the Portfolios are organized, the entities that perform different
services, and how they are compensated.  Further information is available in the
Statement of Additional Information for the Portfolios.

ABOUT WELLS FARGO FUNDS TRUST
Wells Fargo Funds Trust (the "Trust") was organized as a Delaware business trust
on March 10, 1999.  The Board of Trustees of the Trust supervises each
Portfolio's activities, monitors its contractual arrangements with various
service providers and decides upon matters of general policy.

The Trust was created to succeed to the assets and operations of the various
mutual funds in the Stagecoach Family of Funds and the Norwest Advantage Family
of Funds.  The holding company of Wells Fargo Bank, the investment advisor to
the Stagecoach Family of Funds, and the holding company of Norwest Investment
Management, Inc., the investment advisor to the Norwest Advantage Family of
Funds, merged in November 1998.  Each of the Portfolios described in this
prospectus is intended to succeed to the assets and operations of one or more
Stagecoach and/or Norwest Advantage Funds.  One of these predecessor funds is
expected to be the "accounting survivor," which means that its performance and
financial statement history will be assumed by the Wells Fargo Funds Trust
Funds.  The succession transactions are conditioned on shareholder approval by
the shareholders of the various Stagecoach and Norwest Advantage Funds.  The
Table on page __ identifies the expected accounting survivors.

The Board of Trustees of Wells Fargo Funds Trust supervises the Portfolios'
activities and approves the selection of various companies hired to manage the
Portfolios' operation.  The major service providers are described in the diagram
below.  Except for the advisors, which require shareholder vote to change, if
the Board believes that it is in the best interests of the shareholders, it may
make a change in one of these companies.

ORGANIZATION AND MANAGEMENT OF THE PORTFOLIOS (CONT'D)

In the following sections, the percentages shown are the percentages of the
average daily net assets of each Portfolio class paid on an annual basis for the
services described.

THE INVESTMENT ADVISOR
Wells Fargo Bank provides portfolio management and fundamental security analysis
services as the advisor for each of the Portfolios.  Wells Fargo Bank, founded
in 1852, is the oldest bank in the western United States and is one of the
largest banks in the United States.  Wells Fargo Bank is a wholly owned
subsidiary of Wells Fargo & Company, a national bank holding company.  As of
December 31, 1998, Wells Fargo Bank and its affiliates managed over $202 billion
in assets.  For providing these services, Wells Fargo Bank is entitled to
receive .35% of the average daily net assets of each Portfolio.

THE ADMINISTRATOR
Wells Fargo Bank provides the Portfolios with administration services, including
general supervision of each Portfolio's operation, coordination of the other
services provided to each Portfolio, compilation of information for reports to
the SEC and the state securities commissions, preparation of proxy statements
and shareholder reports, and general supervision of data compilation in
connection with preparing periodic reports to the Trust's Trustees and officers.
Wells Fargo Bank also furnishes office space and certain facilities to conduct
each Portfolio's business, and compensates the Trust's Trustees.  For providing
these services, Wells Fargo Bank is entitled to receive a fee of up to .15% of
the average annual net assets of each Portfolio.

YOUR ACCOUNT

This section tells you how Portfolio shares are priced, how to open an account
and how to buy and sell Portfolio shares once your account is open.

PRICING PORTFOLIO SHARES:
 .    As with all mutual fund investments, the price you pay to purchase shares
     or the price you receive when you redeem shares is not determined until
     after a request has been received in proper form.

 .    We determine the Net Asset Value ("NAV") of each class of the Portfolios'
     shares each business day as of the close of regular trading on the NYSE. We
     determine the NAV by subtracting the Portfolio class's liabilities from its
     total assets, and then dividing the result by the total number of
     outstanding shares of that class. Each Portfolio's assets are generally
     valued at current market prices. See the Statement of Additional
     Information for further disclosure.

 .    We process requests to buy or sell shares of the Portfolios each business
     day as of the close of regular trading on the New York Stock Exchange
     ("NYSE"), which is usually 1:00 p.m. (Pacific time)/3:00 p.m. (Central
     time). If the markets close early, the Portfolios may close early and may
     value their shares at earlier times under these circumstances. Any request
     we receive in proper form before these times is processed the same day.
     Requests we receive after the cutoff times are processed the next business
     day.

 .    The Portfolios are open for business on each day the NYSE is open for
     business. NYSE holidays include New Year's Day, Martin Luther King, Jr.
     Day, President's Day, Good Friday, Memorial Day, Independence Day, Labor
     Day, Thanksgiving Day and Christmas Day. When any holiday falls on a
     weekend, the NYSE typically is closed on the weekday immediately before or
     after such holiday.

YOU CAN BUY PORTFOLIO SHARES:
 .    By opening an account directly with the Fund (simply complete and return a
     Wells Fargo Funds application with proper payment);

 .    Through a brokerage account with an approved selling agent; or

 .    Through certain retirement, benefits and pension plans, or through certain
     packaged investment products (please see the providers of the plan for
     instructions).

MINIMUM INVESTMENTS:
 .    $1,000 per Portfolio minimum initial investment.

 .    $100 per Portfolio for all investments after your first.

 .    $100 per Portfolio if you use the Systematic Purchase Program

REDUCED INITIAL SALES CHARGES:
To qualify for a reduced sales charge, you or your Processing Organization must
notify the transfer agent at the time of purchase of your intention to so
qualify and you must provide the transfer agent with sufficient information to
verify that your purchase qualifies for the reduced sales charges, which are as
follows:

GENERAL NOTES FOR SELLING SHARES
- -------------------------------------------------------------------------------------------------
We determine the NAV for the Portfolios at 1:00 p.m. (Pacific time).
- -------------------------------------------------------------------------------------------------
Your redemptions are net of any applicable CDSC.
- -------------------------------------------------------------------------------------------------
We will process requests to sell shares at the first NAV calculated after a request in proper
form is received.  Requests received before the cutoff times are processed on the same business
day.
- -------------------------------------------------------------------------------------------------
If you purchased shares through a packaged investment product or retirement plan, read the
directions for selling shares provided by the product or plan.  There maybe special
requirements that supersede the directions in this Prospectus.
- -------------------------------------------------------------------------------------------------
We reserve the right to delay payment of a redemption so that we may be reasonably certain that
investments made by check or Systematic Purchase Plan have been collected.  Payments of
redemptions also may be delayed under extraordinary circumstances or as permitted by the SEC in
order to protect remaining shareholders.
- -------------------------------------------------------------------------------------------------
Generally, we pay redemption requests in cash, unless the redemption request is for more than
$250,000 or 1% of the net assets of the Portfolio by a single shareholder over any ninety-day
period.  If a request for a redemption is over these limits, it may be to the detriment of
existing shareholders to pay such redemption in cash.  Therefore, we may pay all or part of the
redemption in securities of equal value.
- -------------------------------------------------------------------------------------------------

DISTRIBUTION PLAN
We have adopted a Distribution Plan pursuant to Rule 12b-1 of the 1940 Act.  The
plan authorizes the payment of all or part of the cost of preparing and
distributing prospectuses and distribution-related services including ongoing
compensation to selling agents.  The plan also provides that, if and to the
extent any shareholder servicing payments are recharacterized as payments for
distribution-related services, they are approved and payable under the
distribution plan.  The fees paid under these plans are .75% per Portfolio.

                                       27
<PAGE>

These fees are paid out of the Portfolios' assets on an on-going basis.  Over
time, these fees will increase the cost of your investment and may cost you more
than paying other types of sales charges.

                                       28

EXCHANGES

Exchanges between the Wells Fargo Funds Trust Portfolios are two transactions:
a sale of shares of one Portfolio and the purchase of shares of another.  In
general, the same rules and procedures that apply to sales and purchases apply
to exchanges.  There are, however, additional factors you should keep in mind
while making or considering an exchange:

 .    You should carefully read the Prospectus for the Portfolio into which you
     wish to exchange.

 .    Every exchange involves selling Portfolio shares and that sale may produce
     a capital gain or loss for federal income tax purposes.

 .    If you are making an initial investment into a new Portfolio through an
     exchange, you must exchange at least the minimum first purchase amount of
     the Portfolio you are redeeming, unless your balance has fallen below that
     amount due to market conditions.

 .    Any exchange between Portfolios you already own must meet the minimum
     redemption and subsequent purchase amounts for the Portfolios involved.

 .    In order to discourage excessive Portfolio transaction expenses that must
     be borne by other shareholders, we reserve the right to limit or reject
     exchange orders. Generally, we will notify you 60 days in advance of any
     changes in your exchange privileges.

 .    You may make exchanges between any of the WealthBuilder Portfolios or to
     any Wells Fargo C share Fund that is available. Exchanges into Money Market
     Funds may be made into any A Class Money Market Fund available within the
     Wells Fargo Fund Family.

ADDITIONAL SERVICES AND OTHER INFORMATION

AUTOMATIC PROGRAMS:
These programs help you conveniently purchase and/or redeem shares each month.
Call Investor Services 1-800-222-8222 for more information.

 .    SYSTEMATIC PURCHASE PLAN--With this program, you can regularly purchase
     shares of a Wells Fargo Fund with money automatically transferred from a
     linked bank account. Simply select the Fund you would like to purchase,
     specify an amount of at least $100, and tell us the day of the month you
     would like the money invested. If you do not specify a date, we will
     transfer the money and invest in shares of the Fund you select on or about
     the 25th day of the month.

 .    SYSTEMATIC EXCHANGE PLAN--With this program, you can regularly exchange
     shares of a Wells Fargo Fund you own for shares of another Wells Fargo
     Fund. The exchange amount must be at least $100, and the exchange will take
     place on or about the 25th of each month. See the "Exchanges" section of
     this prospectus for the conditions that apply to your shares. This feature
     may not be available for certain types of accounts.

 .    SYSTEMATIC WITHDRAWAL PLAN--With this program, you can regularly redeem
     shares and receive the proceeds by check or by transfer to a linked bank
     account. Simply specify an amount of at least $100 and we will sell your
     shares equal to that amount on or about the 25th of each month. To
     participate in this program, you:

 .    must have a Fund account value at $10,000 or more;

 .    must have your distributions reinvested; and

 .    may not simultaneously participate in the Systematic Purchase Plan.

It generally takes about ten days to establish a plan once we have received your
instructions.  It generally takes about five days to change or cancel
participation in a plan.  We automatically cancel your program if the linked
bank account your specified is closed.

DIVIDEND AND CAPITAL GAIN DISTRIBUTIONS OPTIONS
The Portfolios in this Prospectus make capital gains distributions at least
annually.  The Portfolios pay any dividends quarterly.

We offer the following distribution options:

 .    AUTOMATIC REINVESTMENT OPTION--Lets you buy new shares of the same class
     of the Fund that generated the distributions. The new shares are purchased
     at NAV generally on the day the income is paid. This option is
     automatically assigned to your account unless you specify another plan.

 .    CHECK PAYMENT OPTION--Allows you to receive checks for distributions
     mailed to your address of record or to another name and address which you
     have specified in written, signature guaranteed instructions. If checks
     remain uncashed for six months or are undeliverable by the Post Office, we
     will reinvest the distributions at the earliest date possible.

TWO THINGS TO KEEP IN MIND ABOUT DISTRIBUTIONS
Remember, distributions have the effect of reducing the NAV per share by the
amount distributed.  Also, distributions on new shares shortly after purchase
would be in effect a return of capital, although the distribution may still be
taxable to you.

                                       30
<PAGE>

TAXES
The following discussion regarding taxes is based on laws that were in effect as
of the date of this Prospectus.  The discussion summarizes only some of the
important tax considerations that affect the Portfolios and you as a
shareholder.  It is not intended as a substitute for careful tax planning.  You
should consult your tax advisor about your specific tax situation.  Federal
income tax considerations are discussed further in the Statement of Additional
Information.

Dividends distributed from the Portfolios attributable to their net interest
income from tax-exempt securities will not be subject to federal income tax.
Dividends distributed from these and the other Portfolios attributable to their
income from other investments and net short-term capital gain (generally, the
excess of net short-term capital gains over net long-term capital losses) will
be taxable to you as ordinary income.  Corporate shareholders may be able to
deduct a portion of their dividends when determining their taxable income.

We will pass on to you any net capital gain (generally the excess of net long-
term capital gains over net short-term capital losses) earned by a Portfolio as
a capital gain distribution.  In general, these distributions will be taxable to
you as long-term capital gains which may qualify for taxation at preferential
rates in the hands of non-corporate shareholders.  Any distribution that is not
from net investment income, short term capital gains, or net capital gain may be
characterized as a return of capital to shareholders.

                             TABLE OF PREDECESSORS

The Portfolios described in this Prospectus were created as part of the
reorganization of the Stagecoach Family of Funds, advised by Wells Fargo Bank,
N.A., and the Norwest Advantage Family of Funds, advised by Norwest Investment
Management, Inc., into a single mutual fund complex.  The reorganization
followed the merger of the advisors' parent companies.  The Portfolios were
previously called Norwest WealthBuilder Growth Portfolio, Norwest WealthBuilder
Growth and Income and Norwest WealthBuilder Growth Balanced Portfolio.

The chart below indicates the predecessor Norwest Advantage Portfolios and the

organizations, such as the International Finance Corporation and the
International Bank for Reconstruction and Development, and the international
financial community to have an "emerging" stock market.  Such markets may be
under-capitalized, have less-developed legal and financial systems or may have
less stable currencies than markets in the developed world.

FDIC
The Federal Deposit Insurance Corporation.  This is the company that provides
federally sponsored insurance covering bank deposits such as savings accounts
and CDs.  Mutual funds are not FDIC insured.

ILLIQUID SECURITY
A security which cannot be readily sold, or cannot be readily sold without
negatively affecting its fair price.

INITIAL PUBLIC OFFERING
The first time a company's stock is offered for sale to the public.

INSTITUTION
An affiliate, franchise or correspondent bank of Wells Fargo & Company and other
institutions.

INVESTMENT-GRADE DEBT
A type of bond rated in the top four investment categories by a nationally
recognized ratings organization.  Generally these are bonds whose issuers are
considered to have a strong ability to pay interest and repay principal,
although some investment-grade bonds may have some speculative characteristics.

LIQUIDITY
The ability to readily sell a security at a fair price.

MONEY MARKET INSTRUMENTS
High-quality short-term instruments meeting the requirements of Rule 2a-7 of the
1940 Act, such as bankers' acceptances, commercial paper, repurchase agreements

does not exceed 90 days, and all investments have maturities of 397 days or less
at the time of purchase.

MOODY'S
A nationally recognized ratings organization.

NET ASSET VALUE (NAV)
The value of a single fund share.  It is determined by adding together all of a
Portfolio's assets, subtracting accrued expenses and other liabilities, then

each class of the Portfolio, and is determined as of the close of regular
trading on each business day the NYSE is open, typically 1:00 P.M. (Pacific
time).

OPTIONS
An option is the right to buy or sell a security based on an agreed upon price
for at a specified time.  For example, an option may give the holder of a stock
the right to sell the stock to another party, allowing the

                            INVESTMENT RESTRICTIONS

     The following discussion is intended to supplement the disclosure in the
Prospectus concerning each Fund's investments, investment techniques and
strategies and risks associated therewith.  No Fund may make any investment or
employ any investment technique or strategy not referenced in the Prospectus
which relates to that Fund.

     Each Fund seeks to achieve its investment objective by investing
substantially all of its investable assets in the securities of affiliated and
non-affiliated open-ended management investment companies or series (the
"Underlying Funds").  Accordingly, the investment experience of each of these
Funds will correspond directly with the investment experience of its respective
Underlying Funds.

     Information concerning each Fund's investment objective is set forth in the
Prospectus for the Funds.  There can be no assurance that the Funds will achieve
their objectives.  The principal features of the Funds' investment programs and
the primary risks associated with those investment programs are discussed in the
Prospectus.  The principal features and certain risks of the Underlying Funds
also are discussed in the Prospectus.  However, since certain Underlying

                                       1
<PAGE>

Funds are non-affiliated with the Advisor or the Funds, there can be no
assurance that the Underlying Funds will follow the stated policies.

     Fundamental Investment Policies
     -------------------------------

     Each Fund has adopted the following investment restrictions, all of which
are fundamental policies; that is, they may not be changed without approval by
the vote of the holders of a majority (as defined in the Investment Company Act
of 1940, as amended (the "1940 Act")) of the outstanding voting securities of
such Fund.

The Funds may not:

     (1)  purchase the securities of issuers conducting their principal business
activity in the same industry if, immediately after the purchase and as a result
thereof, the value of a Fund's investments in that industry would equal 25% of
the current value of the Fund's total assets;

     (2)  purchase securities of any issuer if, as a result, with respect to 75%
of a Fund's total assets, more than 5% of the value of its total assets would be
invested in the securities of any one issuer or, with respect to 100% of its
assets, the Fund's ownership would be more than 10% of the outstanding voting
securities of such issuer.  This policy does not restrict a Fund's ability to
invest in securities issued or guaranteed by the U.S. Government, its agencies
and instrumentalities;

     (3)  borrow money except to the extent permitted by the 1940 Act, and the
rules, regulations and exemptions thereunder;

     (4)  issue senior securities except to the extent permitted by the 1940
Act, and the rules, regulations and exemptions thereunder;

     (5)  make loans to other parties if, as a result, the aggregate value of
such loans would exceed one-third of a Fund's total assets.  For the purposes of
this limitation, entering into repurchase agreements, lending securities and
acquiring any debt securities are not deemed to be the making of loans;

     (6)  underwrite securities of other issuers, except to the extent that the
purchase of permitted investments directly from the issuer thereof or from an
underwriter for an issuer and the later disposition of such securities in
accordance with a Fund's investment program may be deemed to be an underwriting;

     (7)  purchase or sell real estate unless acquired as a result of ownership
of securities or other instruments (but this shall not prevent a Fund from
investing in securities or other instruments backed by real estate or securities
of companies engaged in the real estate business); nor

     (8)  purchase or sell physical commodities unless acquired as a result of
ownership of securities or other instruments (but this shall not prevent the
Funds from purchasing or selling

                                       2
<PAGE>

options and futures contracts or from investing in securities or other
instruments backed by physical commodities).

     Non-Fundamental Investment Policies
     -----------------------------------

     Each Fund has adopted the following non-fundamental policies which may be
changed by a majority vote of the Board of Trustees of the Trust at any time and
without approval of such Fund's shareholders.

     (1)  Each Fund may invest in shares of other open-end management investment
companies, subject to the limitations of the 1940 Act, the rules thereunder, and
any orders obtained thereunder now or in the future. Other investment companies
in which the Funds invest can be expected to charge fees for operating expenses,
such as investment advisory and administration fees, that would be in addition
to those charged by a Fund.

     (2)  Each Fund may not invest or hold more than 15% of the Fund's net
assets in illiquid securities. For this purpose, illiquid securities include,
among others, (a) securities that are illiquid by virtue of the absence of a
readily available market or legal or contractual restrictions on resale, (b)
fixed time deposits that are subject to withdrawal penalties and that have
maturities of more than seven days, and (c) repurchase agreements not terminable
within seven days.

     (3)  Each Fund may invest in futures or options contracts regulated by the
CFTC for (i) bona fide hedging purposes within the meaning of the rules of the
CFTC and (ii) for other purposes if, as a result, no more than 5% of the Fund's
net assets would be invested in initial margin and premiums (excluding amounts
"in-the-money") required to establish the contracts.

          Each Fund (i) will  not hedge more than [50%] of its total assets by
selling futures contracts, buying put options, and writing call options (so
called "short positions"),  (ii) will not buy futures contracts or write put
options whose underlying value exceeds [25%] of the Fund's total assets, and
(iii) will not buy call options with a value exceeding [5%] of the Fund's total
assets.

     (4)  Each Fund may lend securities from its portfolio to brokers, dealers
and financial institutions, in amounts not to exceed (in the aggregate) one-
third of the Fund's total assets. Any such loans of portfolio securities will be
fully collateralized based on values that are marked to market daily. The Funds
will not enter into any portfolio security lending arrangement having a duration
of longer than one year.

     (5)  Each Fund may not make investments for the purpose of exercising
control or management. (Investments by a Fund in entities created under the laws
of foreign countries solely to facilitate investment in securities in that
country will not be deemed the making of investments for the purpose of
exercising control.)

     (6)  Each Fund may not purchase securities on margin (except for short-term
credits necessary for the clearance of transactions).

                                       3
<PAGE>

     (7)  Each Fund may not sell securities short, unless it owns or has the
right to obtain securities equivalent in kind and amount to the securities sold
short (short sales "against the box"), and provided that transactions in futures
contracts and options are not deemed to constitute selling securities short.

     (8)  Each Fund may not purchase interests, leases, or limited partnership
interests in oil, gas, or other mineral exploration or development
programs.

     Notwithstanding the foregoing restrictions, the underlying mutual funds in
which the Funds may invest have adopted their own investment restrictions which
may be more or less restrictive than those listed above, thereby allowing a Fund
of the Trust to participate in certain investment strategies indirectly that are
prohibited under the fundamental and non-fundamental investment restrictions
listed above and in the Prospectus for the Funds.  The investment restrictions
of these Underlying Funds are set forth in their respective Statements of
Additional Information.

        ADDITIONAL PERMITTED INVESTMENT ACTIVITIES AND ASSOCIATED RISKS

     Set forth below are descriptions of certain investments and additional
investment policies for the Funds.  Each Fund seeks to achieve its investment
objective by investing substantially all of its assets in the securities of the
Underlying Funds.  Therefore, although the following discusses the additional
permitted investment activities and associate risks of the Funds, it applies
equally to the Underlying Funds, which may invest in one or more of the
following types of investments.  Thus, as used herein, the term "Funds" shall
refer equally to both the Funds of the Trust as well as the Underlying Funds in
each Fund's portfolio.  However, since certain Underlying Funds are non-
affiliated with the Advisor or the Funds, there can be no assurance that the
Underlying Funds will continue to invest in these permitted investment
activities.

     Although each Fund intends to invest substantially all of its assets in the
Underlying Funds, each Fund reserves the right to invest assets not so invested
in other instruments as outline in the Prospectus.

     Asset-Backed Securities
     -----------------------

     The Funds may invest in various types of asset-backed securities.  Asset-
backed securities are securities that represent an interest in an underlying
security.  The asset-backed securities in which the Funds invest may consist of
undivided fractional interests in pools of consumer loans or receivables held in
trust. Examples include certificates for automobile receivables ("CARS") and
credit card receivables ("CARDS").  Payments of principal and interest on these
asset-backed securities are "passed through" on a monthly or other periodic
basis to certificate holders and are typically supported by some form of credit
enhancement, such as a surety bond, limited guaranty, or subordination. The
extent of credit enhancement varies, but usually amounts to only a fraction of
the asset-backed security's par value until exhausted. Ultimately, asset-backed
securities are dependent upon payment of the consumer loans or receivables by
individuals, and the certificate holder frequently has no recourse to the entity
that originated the loans or receivables.  The actual maturity and realized
yield will vary based upon the prepayment experience of the underlying asset
pool and prevailing interest rates at the time of prepayment.  Asset-backed
securities are relatively

                                       4
<PAGE>

new instruments and may be subject to greater risk of default during periods of
economic downturn than other instruments. Also, the secondary market for certain
asset-backed securities may not be as liquid as the market for other types of
securities, which could result in a Fund experiencing difficulty in valuing or
liquidating such securities. The Funds may also invest in securities backed by
pools of mortgages. The investments are described under the heading "Mortgage-
Related Securities."

     Bank Obligations
     ----------------

     The Funds may invest in bank obligations, including certificates of
deposit, time deposits, bankers' acceptances and other short-term obligations of
domestic banks, foreign subsidiaries of domestic banks, foreign branches of
domestic banks, and domestic and foreign branches of foreign banks, domestic
savings and loan associations and other banking institutions.  With respect to
such securities issued by foreign branches of domestic banks, foreign
subsidiaries of domestic banks, and domestic and foreign branches of foreign
banks, a Fund may be subject to additional investment risks that are different
in some respects from those incurred by a Fund which invests only in debt
obligations of U.S. domestic issuers.  Such risks include possible future
political and economic developments, the possible imposition of foreign
withholding taxes on interest income payable on the securities, the possible
establishment of exchange controls or the adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and interest
on these securities and the possible seizure or nationalization of foreign
deposits.  In addition, foreign branches of U.S. banks and foreign banks may be
subject to less stringent reserve requirements and to different accounting,
auditing, reporting and recordkeeping standards than those applicable to
domestic branches of U.S. banks.

     Certificates of deposit are negotiable certificates evidencing the
obligation of a bank to repay funds deposited with it for a specified period of
time.

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate.  Time
deposits which may be held by a Fund will not benefit from insurance from the
Bank Insurance Fund or the Savings Association Insurance Fund administered by
the Federal Deposit Insurance Corporation ("FDIC").  Bankers' acceptances are
credit instruments evidencing the obligation of a bank to pay a draft drawn on
it by a customer.  These instruments reflect the obligation both of the bank and
of the drawer to pay the face amount of the instrument upon maturity.  The other
short-term obligations may include uninsured, direct obligations, bearing fixed,
floating- or variable-interest rates.

     Bonds
     -----

     Certain of the debt instruments purchased by the Funds may be bonds.  A
bond is an interest-bearing security issued by a company or governmental unit.
The issuer of a bond has a contractual obligation to pay interest at a stated
rate on specific dates and to repay principal (the bond's face value)
periodically or on a specified maturity date. An issuer may have the right to
redeem or "call" a bond before maturity, in which case the investor may have to
reinvest the proceeds at lower market rates.  The value of fixed-rate bonds will
tend to fall when interest rates rise and rise when interest rates fall.  The
value of "floating-rate" or "variable-rate" bonds, on the

                                       5
<PAGE>

other hand, fluctuate much less in response to market interest rate movements
than the value of fixed rate bonds.

     Bonds may be senior or subordinated obligations. Senior obligations
generally have the first claim on a corporation's earnings and assets and, in
the event of liquidation, are paid before subordinated debt.  Bonds may be
unsecured (backed only by the issuer's general creditworthiness) or secured
(also backed by specified collateral).  See also "High Yield/Junk Bonds."

     Commercial Paper
     ----------------

     The Funds may invest in commercial paper (including variable amount master
demand notes) which refers to short-term, unsecured promissory notes issued by
corporations to finance short-term credit needs.  Commercial paper is usually
sold on a discount basis and has a maturity at the time of issuance not
exceeding nine months.  Variable amount master demand notes are demand
obligations which permit the investment of fluctuating amounts at varying market
rates of interest pursuant to arrangements between the issuer and a commercial
bank acting as agent for the payee of such notes whereby both parties have the
right to vary the amount of the outstanding indebtedness on the notes.
Investments by the Funds in commercial paper (including variable rate demand
notes and variable rate master demand notes issued by domestic and foreign bank
holding companies, corporations and financial institutions, as well as similar
instruments issued by government agencies and instrumentalities) will consist of
issues that are rated in one of the two highest rating categories by a
Nationally Recognized Ratings Organization ("NRRO").  Commercial paper may
include variable- and floating-rate instruments.  See also "Nationally
Recognized Ratings Organization."

     Convertible Securities
     ----------------------

     The Funds may invest in convertible securities.  A convertible security is
generally a debt obligation or preferred stock that may be converted within a
specified period of time into a certain amount of common stock of the same or a
different user.  A convertible security provides a fixed-income stream and the
opportunity, through its conversion feature, to participate in the capital
appreciation resulting from a market price advance in its underlying common
stock.  As with a straight fixed-income security, a convertible security tends
to increase in market value when interest rates decline and decrease in value
when interest rates rise.  Like a common stock, the value of a convertible
security also tends to increase as the market value of the underlying stock
rises, and it tends to decrease as the market value of the underlying stock
declines.  Because its value can be influenced by both interest rate and market
movements, a convertible security is not as sensitive to interest rats as a
similar fixed-income security, nor is it as sensitive to changes in share price
as its underlying stock.

     The creditworthiness of the issuer of a convertible security may be
important in determining the security's true value.  This is because the holder
of a convertible security will have recourse only to the issuer.  In addition, a
convertible security may be subject to redemption by the issuer, but only after
a specified date and under circumstances established at the time the security is
issued.

                                       6
<PAGE>

     While the Funds use the same criteria to rate a convertible debt security
that it uses to rate a more conventional debt security, a convertible preferred
stock is treated like a preferred stock for a Funds' financial reporting, credit
rating, and investment limitation purposes.  A preferred stock is subordinated
to all debt obligations in the event of insolvency, and an issuer's failure to
make a dividend payment is generally not an event of default entitling the
preferred shareholder to take action.  A preferred stock generally has no
maturity date, so that its market value is dependent on the issuer's business
prospects for an indefinite period of time.  In addition, distributions from
preferred stock are dividends, rather than interest payments, and are usually
treated as such for corporate tax purposes.

     Derivative Securities
     ---------------------

     The Funds may invest in various instruments that may be considered
"derivatives," including structured notes, bonds or other instruments with
interest rates that are determined by reference to changes in the value of other
interest rates, indices or financial indicators ("References") or the relative
change in two or more References.  Some derivative securities represent
relatively recent innovations in the bond markets, and the trading market for
these instruments is less developed than the markets for traditional types of
debt instruments. It is uncertain how these instruments will perform under
different economic and interest rate scenarios. Because certain of these
instruments are leveraged, their market values may be more volatile than other
types of bonds and may present greater potential for capital gain or loss.
Derivative securities and their underlying instruments may experience periods of
illiquidity, which could cause a Fund to hold a security it might otherwise sell
or could force the sale of a security at inopportune times or for prices that do
not reflect current market value. The possibility of default by the issuer or
the issuer's credit provider may be greater for these structured and derivative
instruments than for other types of instruments.  As new types of derivative
securities are developed and offered to investors, the Advisor will, consistent
with the Funds' investment objective, policies and quality standards, consider
making investments in such new types of derivative securities.

     See also "Futures Contracts and Options."

     Dollar Roll Transactions
     ------------------------

     A Fund may enter into "dollar roll" transactions wherein a Fund sells fixed
income securities, typically mortgage-backed securities, and makes a commitment
to purchase similar, but not identical, securities at a later date from the same
party.  Like a forward commitment, during the roll period no payment is made for
the securities purchased and no interest or principal payments on the security
accrue to the purchaser, but a Fund assumes the risk of ownership.  A Fund is
compensated for entering to dollar roll transactions by the difference between
the current sales price and the forward price for the future purchase, as well
as by the interest earned on the cash proceeds of the initial sale.  Like other
when-issued securities or firm commitment agreements, dollar roll transaction
involve the risk that the market value of the securities sold by a Fund may
decline below the price at which a Fund is committed to purchase similar
securities.  In the event the buyer of securities under a dollar roll
transaction becomes insolvent, the Funds use of the proceeds of the transaction
may be restricted pending a determination by the other party, or its trustee or
receiver, whether to enforce the Funds obligation to repurchase the securities.

                                       7
<PAGE>

     Floating- and Variable-Rate Obligations
     ---------------------------------------

     The Funds may purchase floating- and variable-rate obligations such as
demand notes and bonds.  Variable-rate demand notes include master demand notes
that are obligations that permit a Fund to invest fluctuating amounts, which may
change daily without penalty, pursuant to direct arrangements between a Fund, as
lender, and the borrower.  The interest rate on a floating-rate demand
obligation is based on a known lending rate, such as a bank's prime rate, and is
adjusted automatically each time such rate is adjusted.  The interest rate on a
variable-rate demand obligation is adjusted automatically at specified
intervals.  The issuer of such obligations ordinarily has a right, after a given
period, to prepay in its discretion the outstanding principal amount of the
obligations plus accrued interest upon a specified number of days' notice to the
holders of such obligations.  Frequently, such obligations are secured by
letters of credit or other credit support arrangements provided by banks.

     There generally is no established secondary market for these obligations
because they are direct lending arrangements between the lender and borrower.
Accordingly, where these obligations are not secured by letters of credit or
other credit support arrangements, a Fund's right to redeem is dependent on the
ability of the borrower to pay principal and interest on demand.  Such
obligations frequently are not rated by credit rating agencies and each Fund may
invest in obligations which are not so rated only if the Advisor determines that
at the time of investment the obligations are of comparable quality to the other
obligations in which such Fund may invest.  The Advisor, on behalf of each Fund,
considers on an ongoing basis the creditworthiness of the issuers of the
floating- and variable-rate demand obligations in such Fund's portfolio.  Such
obligations may be treated as liquid, if an active secondary market exists.
Floating- and variable-rate instruments are subject to interest-rate risk and
credit risk.

     The floating- and variable-rate instruments that the Funds may purchase
include certificates of participation in such instruments.

     Foreign Obligations and Securities
     ----------------------------------

     Each Fund may invest in high-quality, short-term debt obligations of
foreign branches of U.S. banks, U.S. branches of foreign banks and short-term
debt obligations of foreign governmental agencies that are denominated in and
pay interest in U.S. dollars. Investments in foreign obligations involve certain
considerations that are not typically associated with investing in domestic
obligations. There may be less publicly available information about a foreign
issuer than about a domestic issuer and the available information may be less
reliable.  In addition, with respect to certain foreign countries, taxes may be
withheld at the source under foreign tax laws, and there is a possibility of
expropriation or confiscatory taxation, political or social instability or
diplomatic developments that could adversely affect investments in, the
liquidity of, and the ability to enforce contractual obligations with respect
to, securities of issuers located in those countries.  The Funds may invest in
securities denominated in currencies other than the U.S. dollar and may
temporarily hold funds in bank deposits or other money market investments
denominated in foreign currencies.  Therefore, the Funds may be affected
favorably or unfavorably by exchange control regulations or changes in the
exchange rate between such currencies and the dollar.  Changes in foreign
currency exchange rates influence values within a Fund from the perspective of
U.S. investors.  The rate of exchange between the U.S. dollar and other
currencies is

                                       8
<PAGE>

determined by the forces of supply and demand in the foreign exchange markets.
These forces are affected by the international balance of payments and other
economic and financial conditions, government intervention, speculation and
other factors.

     The Funds may enter into forward currency exchange contracts ("forward
contracts") to attempt to minimize the risk to the Funds from adverse changes in
the relationship between currencies or to enhance income.  A forward contract is
an obligation to buy or sell a specific currency for an agreed price at a future
date which is individually negotiated and is privately traded by currency
traders and their customers.  The Funds will either cover a position in such a
transaction or maintain, in a segregated account with their custodian bank, cash
or high-grade marketable money market securities having an aggregate value equal
to the amount of any such commitment until payment is made.

     Forward Commitment, When-Issued and Delayed-Delivery Transactions
     -----------------------------------------------------------------

     The Funds may purchase or sell securities on a when-issued or delayed
delivery basis and make contracts to purchase or sell securities for a fixed
price at a future date beyond customary settlement time.  Delivery and payment
on such transaction normally take place within 120 days after the date of the
commitment to purchase.  Securities purchased or sold on a when-issued, delayed-
delivery or forward commitment basis involve a risk of loss if the value of the
security to be purchased declines, or the value of the security to be sold
increases, before the settlement date.  The Funds will establish a segregated
account in which they will maintain cash, U.S. Government obligations or other
high-quality debt instruments in an amount at least equal in value to each such
Fund's commitments to purchase when-issued securities. If the value of these
assets declines, a Fund will place additional liquid assets in the account on a
daily basis so that the value of the assets in the account is equal to the
amount of such commitments.

     Futures Contracts and Options
     -----------------------------

     A Fund may seek to enhance its return through the writing (selling) and
purchasing of exchange-traded and over-the-counter options on fixed income
securities or indices.  A Fund may also attempt to hedge against a decline in
the value of securities owned by it or an increase in the price of securities
which it plans to purchase through the use of those options and the purchase and
sale of interest rate futures contracts and options on those futures contracts.
These instruments are often referred to as "derivatives," which may be defined
as financial instruments whose performance is derived, at least in part, from
the performance of another asset (such as a security, currency or an index of
securities).

     A call option is a contract pursuant to which the purchaser of the call
option, in return for a premium paid, has the right to buy the security
underlying the option at a specified exercise price at any time during the term
of the option.  The writer of the call option, who receives the premium, has the
obligation upon exercise of the option to deliver the underlying security
against payment of the exercise price during the option period.  A put option
gives its purchaser, in return for a premium, the right to sell the underlying
security at a specified price during the term of the option.  The writer of the
put, who receives the premium, has the obligation to buy the underlying
security, upon exercise at the exercise price during the option period.  The
amount of premium received or paid is based upon certain factors, including the
market price of the

                                       9
<PAGE>

underlying security or index, the relationship of the exercise price to the
market price, the historical price volatility of the underlying security or
index, the option period, supply and demand and interest rates.

     Certain futures strategies employed by a Fund in making temporary
allocations may not be deemed to be for bona fide hedging purposes, as defined
by the Commodity Futures Trading Commission.

     A Fund's use of options and futures contracts subjects a Fund to certain
investment risks and transaction costs to which it might not otherwise be
subject.  These risks include:  (1) dependence on the Advisor's ability to
predict movements in the prices of individual securities and fluctuations in the
general securities markets; (2) imperfect correlations between movements in the
prices of options or futures contracts and movements in the price of the
securities hedged or used for cover which may cause a given hedge not to achieve
its objective; (3) the fact that the skills and techniques needed to trade these
instruments are different from those needed to select the other securities in
which a Fund invests; (4) lack of assurance that a liquid secondary market will
exist for any particular instrument at any particular time, which, among other
things, may hinder a Fund's ability to limit exposures by closing its positions;
(5) the possible need to defer closing out of certain options, futures contracts
and related options to avoid adverse tax consequences; and (6) the potential for
unlimited loss when investing in futures contracts or writing options for which
an offsetting position is not held.

     Other risks include the inability of a Fund, as the writer of covered call
options, to benefit from any appreciation of the underlying securities above the
exercise price and the possible loss of the entire premium paid for options
purchased by a Fund.  In addition, the futures exchanges may limit the amount of
fluctuation permitted in certain futures contract prices during a single trading
day.  A Fund may be forced, therefore, to liquidate or close out a futures
contract position at a disadvantageous price.  There can be no assurance that a
liquid market will exist at a time when a Fund seeks to close out a futures
position or that a counterparty in an over-the-counter option transaction will
be able to perform its obligations.

     Guaranteed Investment Contracts
     -------------------------------

     The Funds may invest in guaranteed investment contracts ("GICs") issued by
insurance companies.  Pursuant to such contracts, a Fund makes cash
contributions to a deposit fund of the insurance company's general account.  The
insurance company then credits to the deposit fund on a monthly basis guaranteed
interest at a rate based on an index.  The GICs provide that this guaranteed
interest will not be less than a certain minimum rate.  The insurance company
may assess periodic charges against a GIC for expense and service costs
allocable to it, and these charges will be deducted from the value of the
deposit fund.  A Fund will purchase a GIC only when the Investment Adviser has
determined that the GIC presents minimal credit risks to the Fund and is of
comparable quality to instruments in which the Fund may otherwise invest.
Because a Fund may not receive the principal amount of a GIC from the insurance
company on seven days' notice or less, a GIC may be considered an illiquid
investment.  The term of a GIC will be one year or less.

                                       10
<PAGE>

     The interest rate on a GIC may be tied to a specified market index and is
guaranteed not to be less than a certain minimum rate.

     High Yield/Junk Bonds
     ---------------------

     The Funds may invest in high yield bonds, also known as "junk bonds."
Securities rated less than Baa by Moody's or BBB by S&P are classified as non-
investment grade securities and are considered speculative by those rating
agencies.  Junk bonds may be issued as a consequence of corporate
restructurings, such as leveraged buyouts, mergers, acquisitions, debt
recapitalizations, or similar events or by smaller or highly leveraged
companies.  Although the growth of high yield/high risk securities market in the
1980's had paralleled a long economic expansion, many issuers subsequently have
been affected by adverse economic and market conditions.  It should be
recognized that an economic downturn or increase in interest rates is likely to
have a negative effect on:  (1) the high yield bond market; (2) the value of
high yield/high risk securities; and (3) the ability of the securities' issuers
to service their principal and interest payment obligations, to meet their
projected business goals or to obtain additional financing.  In addition, the
market for high yield/high risk securities, which is concentrated in relatively
few market makers, may not be as liquid as the market for investment grade
securities.  Under adverse market or economic conditions, the market for high
yield/high risk securities could contract further, independent of any specific
adverse changes in the condition of a particular issuer.  As a result, a Fund
could find it more difficult to sell these securities or may be able to sell the
securities only at prices lower than if such securities were widely traded.
Prices realized upon the sale of such lower rated or unrated securities, under
these circumstances, may be less than the prices used in calculating a Fund's
net asset value.

     In periods of reduced market liquidity, prices of high yield/high risk
securities may become more volatile and may experience sudden and substantial
price declines.  Also, there may be significant disparities in the prices quoted
for high yield/high risk securities by various dealers.  Under such conditions,
a Fund may have to use subjective rather than objective criteria to value its
high yield/high risk securities investments accurately and rely more heavily on
the judgment of the Advisor.

     Lower rated or unrated debt obligations also present risks based on payment
expectations.  If an issuer calls the obligation for redemption, the Advisor may
have to replace the security with a lower yielding security, resulting in a
decreased return for investors.  If a Fund experiences unexpected net
redemptions, the Advisor may be forced to sell a Fund's higher rated securities,
resulting in a decline in the overall credit quality of a Fund's investment
portfolio and increasing the exposure of a Fund to the risks of high yield/high
risk securities.

     Illiquid Securities
     -------------------

     The Funds may invest in securities not registered under the Securities Act
of 1933, as amended (the "1933 Act") and other securities subject to legal or
other restrictions on resale. Because such securities may be less liquid than
other investments, they may be difficult to sell promptly at an acceptable
price. Delay or difficulty in selling securities may result in a loss or be
costly to a Fund.

                                       11
<PAGE>

     Loans of Portfolio Securities
     -----------------------------

     Each Fund may lend its portfolio securities to brokers, dealers and
financial institutions, provided: (1) the loan is secured continuously by
collateral consisting of U.S. Government securities or cash or letters of credit
maintained on a daily marked-to-market basis in an amount at least equal to the
current market value of the securities loaned; (2) such Fund may at any time
call the loan and obtain the return of the securities loaned within five
business days; (3) such Fund will receive any interest or dividends paid on the
loaned securities; and (4) the aggregate market value of securities loaned will
not at any time exceed the limits established by the 1940 Act.

     A Fund will earn income for lending its securities because cash collateral
pursuant to these loans will be invested in short-term money market instruments.
In connection with lending securities, a Fund may pay reasonable finders,
administrative and custodial fees.  A Fund will not enter into any security
lending arrangement having a duration longer than one year.  Loans of securities
involve a risk that the borrower may fail to return the securities or may fail
to provide additional collateral.  In either case, a Fund could experience
delays in recovering securities or collateral or could lose all or part of the
value of the loaned securities.  Although voting rights, or rights to consent,
attendant to securities on loan pass to the borrower, such loans may be called
at any time and will be called so that the securities may be voted by a Fund if
a material event affecting the investment is to occur.  A Fund may pay a portion
of the interest or fee earned from securities lending to a borrower or a placing
broker.  Borrowers and placing brokers may not be affiliated, directly or
indirectly with Wells Fargo Bank, Stephens, Norwest or any of their affiliates.

     Nationally Recognized Ratings Organizations
     -------------------------------------------

     The ratings of Moody's, S&P, divisions of McGraw Hill, Duff & Phelps Credit
Rating Co., Fitch Investors Service, Inc., Thomson Bank Watch and IBCA Inc.
represent their opinions as to the quality of debt securities.  It should be
emphasized, however, that ratings are general and not absolute standards of
quality, and debt securities with the same maturity, interest rate and rating
may have different yields while debt securities of the same maturity and
interest rate with different ratings may have the same yield.  Subsequent to
purchase by the Funds, an issue of debt securities may cease to be rated or its
rating may be reduced below the minimum rating required for purchase by the
Funds.  The Advisor will consider such an event in determining whether the Fund
involved should continue to hold the obligation.

     See "Appendix A" regarding the ratings systems of Moody's and S&P.

     Mortgage-Related Securities
     ---------------------------

     The Funds may invest in mortgage-related securities.  Mortgage pass-through
securities are securities representing interests in "pools" of mortgages in
which payments of both interest and principal on the securities are made
monthly, in effect "passing through" monthly payments made by the individual
borrowers on the residential mortgage loans which underlie the securities (net
of fees paid to the issuer or guarantor of the securities).  Payment of
principal and interest on some mortgage pass-through securities (but not the
market value of the securities themselves) may be guaranteed by the full faith
and credit of the U.S. Government or its agencies or instrumentalities.

                                       12
<PAGE>

Mortgage pass-through securities created by non- government issuers (such as
commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers) may be supported
by various forms of insurance or guarantees, including individual loan, title,
pool and hazard insurance, and letters of credit, which may be issued by
governmental entities, private insurers or the mortgage poolers.

     Prepayment Risk.  The stated maturities of mortgage-related securities may
be shortened by unscheduled prepayments of principal on the underlying
mortgages.  Therefore, it is not possible to predict accurately the average
maturity of a particular mortgage-related security.  Variations in the
maturities of mortgage-related securities will affect the yield of the Funds.
Early repayment of principal on mortgage-related securities may expose a Fund to
a lower rate of return upon reinvestment of principal. Also, if a security
subject to prepayment has been purchased at a premium, in the event of
prepayment the value of the premium would be lost. Like other fixed-income
securities, when interest rates rise, the value of a mortgage-related security
generally will decline; however, when interest rates decline, the value of
mortgage-related securities with prepayment features may not increase as much as
other fixed-income securities.

     Collateralized Mortgage Obligations ("CMOs") and Adjustable Rate Mortgages
("ARMs").  The Funds may also invest in investment grade CMOs.  CMOs may be
collateralized by whole mortgage loans but are more typically collateralized by
portfolios of mortgage pass-through securities guaranteed by the Government
National Mortgage Association ("GNMA"), the Federal Home Loan Mortgage
Corporation ("FHLMC") or Federal National Mortgage Association ("FNMA").  CMOs
are structured into multiple classes, with each class bearing a different stated
maturity. Payments of principal, including prepayments, are first returned to
investors holding the shortest maturity class; investors holding the longer
maturity classes receive principal only after the first class has been retired.
As new types of mortgage-related securities are developed and offered to
investors, the Advisor will, consistent with a Fund's investment objective,
policies and quality standards, consider making investments in such new types of
mortgage-related securities.

     The Funds each may invest in ARMs issued or guaranteed by the GNMA, FNMA or
the FHLMC.  The full and timely payment of principal and interest on GNMA ARMs
is guaranteed by GNMA and backed by the full faith and credit of the U.S.
Government.  FNMA also guarantees full and timely payment of both interest and
principal, while FHLMC guarantees full and timely payment of interest and
ultimate payment of principal. FNMA and FHLMC ARMs are not backed by the full
faith and credit of the United States.  However, because FNMA and FHLMC are
government-sponsored enterprises, these securities are generally considered to
be high quality investments that present minimal credit risks.  The yields
provided by these ARMs have historically exceeded the yields on other types of
U.S. Government securities with comparable maturities, although there can be no
assurance that this historical performance will continue.

     The mortgages underlying ARMs guaranteed by GNMA are typically insured or
guaranteed by the Federal Housing Administration, the Veterans Administration or
the Farmers Home Administration, while those underlying ARMs issued by FNMA or
FHLMC are typically conventional residential mortgages which are not so insured
or guaranteed, but which conform to specific underwriting, size and maturity
standards.

                                       13
<PAGE>

     The interest rates on the mortgages underlying the ARMs and some of the
CMOs in which the Funds may invest generally are readjusted at periodic
intervals ranging from one year or less to several years in response to changes
in a predetermined commonly-recognized interest rate index.  The adjustable rate
feature should reduce, but will not eliminate, price fluctuations in such
securities, particularly when market interest rates fluctuate.  The net asset
value of a Funds' shares may fluctuate to the extent interest rates on
underlying mortgages differ from prevailing market interest rates during interim
periods between interest rate reset dates.  Accordingly, investors could
experience some loss if they redeem their shares of a Fund or if a Fund sells
these portfolio securities before the interest rates on the underlying mortgages
are adjusted to reflect prevailing market interest rates.  The holder of ARMs
and CMOs are also subject to repayment risk.

     The Funds will not invest in CMOs that, at the time of purchase, are "high-
risk mortgage securities" as defined in the then current Federal Financial
Institutions Examination Council Supervisory Policy Statement on Securities
Activities.  High-risk mortgage securities are generally those with long
durations or those which are likely to be more sensitive to interest-rate
fluctuations.

     Mortgage Participation Certificates.  The Short-Intermediate U.S.
Government Income Fund and Intermediate Government Income Fund also may invest
in the following types of FHLMC mortgage pass-through securities.  FHLMC issues
two types of mortgage pass-through securities: mortgage participation
certificates ("PCs") and guaranteed mortgage certificates ("GMCs"). PCs resemble
GNMA certificates in that each PC represents a pro rata share of all interest
and principal payments made and owed on the underlying pool of mortgages.  GMCs
also represent a pro rata interest in a pool of mortgages. These instruments,
however, pay interest semiannually and return principal once a year in
guaranteed minimum payments.  These mortgage pass-through securities differ from
bonds in that principal is paid back by the borrower over the length of the loan
rather than returned in a lump sum at maturity. They are called "pass-through"
securities because both interest and principal payments, including prepayments,
are passed through to the holder of the security.  PCs and GMCs are both subject
to prepayment risk.

     Municipal Bonds
     ---------------

     The Funds may invest in municipal bonds.  The two principal classifications
of municipal bonds are "general obligation" and "revenue" bonds.  Municipal
bonds are debt obligations issued to obtain funds for various public purposes.
Industrial development bonds are a specific type of revenue bond backed by the
credit and security of a private user.  Certain types of industrial development
bonds are issued by or on behalf of public authorities to obtain funds to
provide privately-operated facilities.

     From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal obligations.  For example, under federal tax legislation
enacted in 1986, interest on certain private activity bonds must be included in
an investor's alternative minimum taxable income, and corporate investors must
treat all tax-exempt interest as an item of tax preference.  Moreover the Funds
cannot predict what legislation, if any, may be proposed in the state
legislature regarding the state income tax status of interest on such
obligations, or which proposals, if any, might be enacted.  Such proposals,
while pending or if enacted, might materially and adversely affect the
availability of municipal obligations generally for investment by the Funds and
the liquidity and value of a

                                       14
<PAGE>

Fund's portfolio. In such an event, a Fund would re-evaluate its investment
objective and policies and consider possible changes in its structure or
possible dissolution.

     Certain of the municipal obligations held by a Fund may be insured as to
the timely payment of principal and interest.  The insurance policies usually
are obtained by the issuer of the municipal obligation at the time of its
original issuance.  In the event that the issuer defaults on interest or
principal payment, the insurer will be notified and will be required to make
payment to the bondholders.  There is, however, no guarantee that the insurer
will meet its obligations.  In addition, such insurance does not protect against
market fluctuations caused by changes in interest rates and other factors.

     Municipal Notes.  The Funds may invest in municipal notes.  Municipal notes
include, but are not limited to, tax anticipation notes ("TANs"), bond
anticipation notes ("BANs"), revenue anticipation notes ("RANs") and
construction loan notes.  Notes sold as interim financing in anticipation of
collection of taxes, a bond sale or receipt of other revenues are usually
general obligations of the issuer.

     TANs.  An uncertainty in a municipal issuer's capacity to raise taxes as a
result of such events as a decline in its tax base or a rise in delinquencies
could adversely affect the issuer's ability to meet its obligations on
outstanding TANs.  Furthermore, some municipal issuers mix various tax proceeds
into a general fund that is used to meet obligations other than those of the
outstanding TANs.  Use of such a general fund to meet various obligations could
affect the likelihood of making payments on TANs.

     BANs.  The ability of a municipal issuer to meet its obligations on its
BANs is primarily dependent on the issuer's adequate access to the longer term
municipal bond market and the likelihood that the proceeds of such bond sales
will be used to pay the principal of, and interest on, BANs.

     RANs.  A decline in the receipt of certain revenues, such as anticipated
revenues from another level of government, could adversely affect an issuer's
ability to meet its obligations on outstanding RANs.  In addition, the
possibility that the revenues would, when received, be used to meet other
obligations could affect the ability of the issuer to pay the principal of, and
interest on, RANs.

     The values of outstanding municipal securities will vary as a result of
changing market evaluations of the ability of their issuers to meet the interest
and principal payments (i.e., credit risk).  Such values also will change in
response to changes in the interest rates payable on new issues of municipal
securities (i.e., market risk).  Changes in the value of municipal securities
held in a Fund's portfolio arising from these or other factors will cause
changes in the net asset value per share of a Fund.

     Other Investment Companies
     --------------------------

     The principal investment strategy of each Fund is to invest in shares of
other open-end management investment companies, up to the limits prescribed in
Section 12(d) of the 1940 Act and pursuant to the portfolio allocation
percentages discussed in the Prospectus.  Each Fund seeks to achieve its
investment objective by investing substantially all of its investable assets in
the

                                       15
<PAGE>

securities of affiliated and non-affiliated open-ended management investment
companies or series (the "Underlying Funds").  Accordingly, the investment
experience of each of these Funds will correspond directly with the investment
experience of its respective Underlying Funds.  Under the 1940 Act, a Fund's
investment in such securities currently is limited to, subject to certain
exceptions, (i) 3% of the total voting stock of any one investment company, (ii)
5% of such Fund's net assets with respect to any one investment company and
(iii) 10% of such Fund's net assets in aggregate.  Other investment companies in
which the Funds invest can be expected to charge fees for operating expenses,
such as investment advisory and administration fees, that would be in addition
to those charged by the Funds.

     Repurchase Agreements
     ---------------------

     Each Fund may enter into repurchase agreements, wherein the seller of a
security to a Fund agrees to repurchase that security from a Fund at a mutually
agreed upon time and price.  A Fund may enter into repurchase agreements only
with respect to securities that could otherwise be purchased by such Fund.  All
repurchase agreements will be fully collateralized at 102% based on values that
are marked to market daily.  The maturities of the underlying securities in a
repurchase agreement transaction may be greater than twelve months, although the
maximum term of a repurchase agreement will always be less than twelve months.
If the seller defaults and the value of the underlying securities has declined,
a Fund may incur a loss.  In addition, if bankruptcy proceedings are commenced
with respect to the seller of the security, the Funds' disposition of the
security may be delayed or limited.

     A Fund may not enter into a repurchase agreement with a maturity of more
than seven days, if, as a result, more than 15% of the market value of such
Fund's total net assets would be invested in repurchase agreements with
maturities of more than seven days, restricted securities and illiquid
securities.  A Fund will only enter into repurchase agreements with primary
broker/dealers and commercial banks that meet guidelines established by the
Board of Trustees and that are not affiliated with the Advisor.  The Funds may
participate in pooled repurchase agreement transactions with other funds advised
by Wells Fargo Bank.

     Reverse Repurchase Agreements
     -----------------------------

     The Funds may enter into reverse repurchase agreements.  Reverse repurchase
agreements are transactions in which a Fund sells a security and simultaneously
commits to repurchase that security from the buyer at an agreed upon price on an
agreed upon future date.  The resale price in a reverse repurchase agreement
reflects a market rate of interest that is not related to the coupon rate or
maturity of the sold security.  For certain demand agreements, there is no
agreed upon repurchase date and interest payments are calculated daily, often
based the prevailing overnight repurchase rate.  Because certain of the
incidents of ownership of the security are retained by a Fund, reverse
repurchase agreements may be viewed as a form of borrowing by a Fund from the
buyer, collateralized by the security sold by the Fund.  A Fund will use the
proceeds of reverse repurchase agreements to Fund redemptions or to make
investments.  In most cases these investments either mature or have a demand
feature to resell to the issuer on a date not later than the expiration of the
agreement.  Interest costs on the money received in a reverse repurchase
agreement may exceed the return received on the investments made by the Fund
with those

                                       16
<PAGE>

monies. Any significant commitment of a Fund's assets to the reverse repurchase
agreements will tend to increase the volatility of a Fund's net asset value per
share.

     Short Sales
     -----------

     The Funds may make short sales of securities they own or have the right to
acquire at no added cost through conversion or exchange of other securities they
own (referred to as short sales "against the box") and to make short sales of
securities which they do not own or have the right to acquire.  A short sale
that is not made "against the box" is a transaction in which a Fund sells a
security it does not own in anticipation of a decline in the market price for
the security.  When a Fund makes a short sale, the proceeds it receives are
retained by the broker until that Fund replaces the borrowed security.  In order
to deliver the security to the buyer, a Fund must arrange through a broker to
borrow the security and, in so doing, a Fund becomes obligated to replace the
security borrowed at its market price at the time of replacement, whatever the
price may be.

     Short sales that are not made "against the box" create opportunities to
increase the Fund's return but, at the same time, involve special risk
considerations and may be considered a speculative technique.  Since the Fund in
effect profits from a decline in the price of the securities sold short without
the need to invest the full purchase price of the securities on the date of the
short sale, the Fund's net asset value per share will tend to increase more when
the securities it has sold short decrease in value, and to decrease more when
the securities it has sold increase in value, than would otherwise be the case
if it had not engaged in such short sales.  Short sales theoretically involve
unlimited loss potential, as the market price of securities sold short may
continuously increase, although a Fund may mitigate such losses by replacing the
securities sold short before the market price has increased significantly.
Under adverse market conditions a Fund may have difficulty purchasing securities
to meet its short sale delivery obligations and might have to sell portfolio
securities to raise the capital necessary to meet its short sale obligations at
a time when fundamental investment considerations would not favor those sales.

     If the Fund makes a short sale "against the box," the Fund would not
immediately deliver the securities sold and would not receive the proceeds from
the sale.  The seller is said to have a short position in the securities sold
until it delivers the securities sold, at which time it receives the proceeds of
the sale.  The Fund's decision to make a short sale "against the box" may be a
technique to hedge against market risks when the Advisor believes that the price
of a security may decline, causing a decline in the value of a security owned by
the Fund or a security  convertible into or exchangeable for such security.  In
such case, any future losses in the Fund's long position would be reduced by an
offsetting future gain in the short position.  The Fund's ability to enter into
short sales transactions is limited by certain tax requirements.

     Each Fund may not sell securities short, unless it owns or has the right to
obtain securities equivalent in kind and amount to the securities sold short
(short sales "against the box"), and provided that transactions in futures
contracts and options are not deemed to constitute selling securities short

     Stripped Securities
     -------------------

     The Funds may purchase Treasury receipts, securities of government-
sponsored enterprises ("GSEs"), and other "stripped" securities that evidence
ownership in either the future interest payments or the future principal
payments on U.S. Government and other obligations.  The stripped securities the
Funds may purchase are issued by the U.S. Government (or a U.S. Government
agency or instrumentality) or by private issuers such as banks, corporations and
other institutions at a discount to their face value.  The Funds will not
purchase stripped mortgage-backed securities ("SMBS").  The stripped securities
purchased by the Funds generally are structured to make a lump-sum payment at
maturity and do not make periodic payments of principal or interest.  Hence, the
duration of these securities tends to be longer and they are therefore more
sensitive to interest rate fluctuations than similar securities that offer
periodic payments over time.  The stripped securities purchased by the Funds are
not subject to prepayment or extension risk.

     The Funds may purchase participations in trusts that hold U.S. Treasury
securities (such as TIGRs and CATS) or other obligations where the trust
participations evidence ownership in either the future interest payments or the
future principal payments on the obligations. These participations are normally
issued at a discount to their "face value," and can exhibit greater price
volatility than ordinary debt securities because of the way in which their
principal and interest are returned to investors. Investments by the Funds in
such participations will not exceed 5% of the value of the Funds' total assets.

     Swap Agreements
     ---------------

     To manage its exposure to different types of investments, a Fund may enter
into interest rate, currency and mortgage (or other asset) swap agreements and
may purchase and sell interest rate "caps," "floors" and "collars."  In a
typical interest rate swap agreement, one party agrees to make regular payments
equal to a floating interest rate on a specified amount (the "notional principal
amount") in return for payments equal to a fixed interest rate on the same
amount for a specified period.  If a swap agreement provides for payment in
different currencies, the parties may also agree to exchange the notional
principal amount.  Mortgage swap agreements are similar to interest rate swap
agreements, except that the notional principal amount is tied to a reference
pool of mortgages.  In a cap or floor arrangement, one party agrees, usually in
return for a fee, to make payments under particular circumstances.  For example,
the purchaser of an interest rate cap has the right to receive payments to the
extent a specified interest rate exceeds a agreed upon level; the purchaser of
an interest rate floor has the right to receive payments to the extent a
specified interest rate falls below an agreed upon level.  A collar arrangement
entitles the purchaser to receive payments to the extent a specified interest
rate falls outside an agreed upon range.

     Swap agreements may involve leverage and may be highly volatile; depending
on how they are used they may have a considerable impact on the Fund's
performance.  Swap agreements involve risks depending upon the counterparties'
creditworthiness and ability to perform as well as the Fund's ability to
terminate its swap agreements or reduce its exposure through offsetting
transactions.

     U.S. Government Obligations
     ---------------------------

     The Funds may invest in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Obligations").
Payment of principal and interest on U.S. Government Obligations (i) may be
backed by the full faith and credit of the United States (as with U.S. Treasury
bills and GNMA certificates) or (ii) may be backed solely by the issuing or
guaranteeing agency or instrumentality itself (as with FNMA notes).  In the
latter case investors must look principally to the agency or instrumentality
issuing or guaranteeing the obligation for ultimate repayment, which agency or
instrumentality may be privately owned.  There can be no assurance that the U.S.
Government will provide financial support to its agencies or instrumentalities
where it is not obligated to do so.  In addition, U.S. Government Obligations
are subject to fluctuations in market value due to fluctuations in market
interest rates. As a general matter, the value of debt instruments, including
U.S. Government Obligations, declines when market interest rates increase and
rises when market interest rates decrease.  Certain types of U.S. Government
Obligations are subject to fluctuations in yield or value due to their structure
or contract terms.

     Warrants
     --------

     The Funds may invest in warrants.  A warrant is an option to purchase an
equity security at a specified price (usually representing a premium over the
applicable market value of the underlying equity security at the time of the
warrant's issuance) and usually during the specified period of time.  The price
of warrants does not necessarily move parallel to the prices of the underlying
securities.  Warrants have no voting rights, receive no dividends and have no
rights with respect to the assets of the issuer.  Unlike convertible securities
and preferred stocks, warrants do not pay a fixed dividend.  Investments in
warrants involve certain risks, including the possible lack of a liquid market
for the resale of the warrants, potential price fluctuations as a result of a
speculation or other factors and failure of the price of the underlying security
to reach a level at which the warrant can be prudently exercised.  To the extent
that the market value of the security that may be purchased upon exercise of the
warrant rises above the exercise price, the value of the warrant will tend to
rise.  To the extent that the exercise price equals or exceed the market value
of such security, the warrants will have little or no market value.  If a
warrant is not exercised within the specified time period, it will become
worthless and the Fund will lose the purchase price paid for the warrant and the
right to purchase the underlying security.

     Zero Coupon Bonds
     -----------------

     The Funds may invest in zero coupon bonds.  Zero coupon bonds are
securities that make no periodic interest payments, but are instead sold at
discounts from face value.  The buyer of such a bond receives the rate of return
by the gradual appreciation of the security, which is redeemed at face value on
a specified maturity date.  Because zero coupon bonds bear no interest, they are
more sensitive to interest-rate changes and are therefore more volatile.  When
interest rates rise, the discount to face value of the security deepens and the
securities decrease more rapidly in value, when interest rates fall, zero coupon
securities rise more rapidly in value because the bonds carry fixed interest
rates that become more attractive in a falling interest rate environment.

     Each of the Trustees and Officers listed above, act in the identical
capacities for Wells Fargo Variable Trust and Wells Fargo Core Trust
(collectively the "Fund Complex").  Trustees are compensated annually by the
Trust and by all the registrants in each fund complex they serve beginning
September 17, 1999, and beginning March 26, 1999, receive a per-meeting fee of
$250.  Trustees also are reimbursed for all out-of-pocket expenses relating to
attendance at board meetings.  Each of the Trustees and Officers of the Trust
serves in the identical capacity as trustees and/or officers of each registered
open-end management investment company in the Fund Complex.  The Trustees are
compensated by other companies and trusts within a fund complex for their
services as directors/trustees to such companies and trusts.  Currently the
Trustees do not receive any retirement benefits or deferred compensation from
the Trust or any other member of each fund complex.

     As of the date of this SAI, Trustees and Officers of the Trust as a group
beneficially owned less than 1% of the outstanding shares of the Trust.

     Investment Advisor.  Wells Fargo Bank, N.A. ("Wells Fargo Bank") provides
     ------------------
investment advisory services to the Funds.  As the Advisor, Wells Fargo Bank
furnishes investment guidance and policy direction in connection with the daily
portfolio management of the Funds. Wells Fargo Bank furnishes to the Trust's
Board of Trustees periodic reports on the investment strategy and performance of
each Fund.  Wells Fargo Bank provides the Funds with, among other things, money
market security and fixed-income research, analysis and statistical and economic
data and information concerning interest rate and securities markets trends,
portfolio composition, and credit conditions.

     As compensation for its advisory services, Well Fargo Bank is entitled to
receive a monthly fee at the annual rates indicated below of each Fund's average
daily net assets:

</TABLE>

     General.  Each Fund's Advisory Contract will continue in effect for more
     -------
than two years from the effective date provided the continuance is approved
annually (i) by the holders of a majority of the respective Fund's outstanding
voting securities or by the Trust's Board of Trustees and (ii) by a majority of
the Trustees of the Trust who are not parties to the Advisory Contract or
"interested persons" (as defined in the 1940 Act) of any such party.  A Fund's
Advisory Contract may be terminated on 60 days' written notice by either party
and will terminate automatically if assigned.

     The Funds are unique from the other funds of the Trust in that, as a "fund
of funds" which invests all of their assets in the Underlying Funds, the Funds
do not have an investment sub-advisor.

                                       22

     Portfolio Manager.  The following people are responsible for the day-to-day
     -----------------
operations of the Funds:

     Galen Blomster, Ph.D., CFA
     Principal

     Dr. Blomster will co-manage the Funds upon inception.  Dr. Blomster joins
     Wells Fargo Bank from Norwest Investment Management, Inc. ("NIM"), where
     he was Vice President & Director of Research.  He has been associated
     with NIM and its affiliates since 1977.

     In addition to his responsibilities for the Funds, the portfolio manager
may perform portfolio management and other duties for other funds of the Trust

     Administrator.  The Trust has retained Wells Fargo Bank as Administrator on
     -------------
behalf of each Fund.  Under the Administration Agreement between Wells Fargo
Bank and the Trust, Wells Fargo Bank shall provide as administration services,
among other things:  (i) general supervision of the Funds' operations, including
coordination of the services performed by each Fund's Advisor, transfer agent,
custodian, shareholder servicing agent(s), independent auditors and legal
counsel, regulatory compliance, including the compilation of information for
documents such as reports to, and filings with, the U.S. Securities and Exchange
Commission ("SEC") and state securities commissions; and preparation of proxy
statements and shareholder reports for each Fund; and (ii) general supervision
relative to the compilation of data required for the preparation of periodic
reports distributed to the Trust's officers and Board of Trustees.  Wells Fargo
Bank also furnish office space and certain facilities required for conducting
the Funds' business together with ordinary clerical and bookkeeping services.
The Administrator is entitled to receive a fee of 0.15% of average daily net
assets on an annual basis.

     Distributor.  Stephens Inc. ("Stephens," the "Distributor"), located at 111
     -----------
Center Street, Little Rock, Arkansas  72201, serves as Distributor for the
Funds.  The Funds have adopted a distribution plan (a "Plan") under Section
12(b) of the 1940 Act and Rule 12b-1 thereunder (the "Rule").  The Plan was
adopted by the Trust's Board of Trustees, including a majority of the Trustees
who were not "interested persons" (as defined in the 1940 Act) of the Funds and
who had no direct or indirect financial interest in the operation of the Plan or
in any agreement related to the Plan (the "Non-Interested Trustees").

     Under the Plan and pursuant to the related Distribution Agreement, each
Fund pays Stephens up to 0.75% of the average daily net assets of the Fund as
compensation for distribution-related services or as reimbursement for
distribution-related expenses.

     The actual fee payable to the Distributor by the above-indicated Funds is
determined, within such limits, from time to time by mutual agreement between
the Trust and the Distributor and will not exceed the maximum sales charges
payable by mutual funds sold by members of the National Association of
Securities Dealers, Inc. ("NASD") under the Conduct Rules of the NASD.  The
Distributor may enter into selling agreements with one or more selling agents
(which may include Wells Fargo Bank and its affiliates) under which such agents
may receive compensation for distribution-related services from the Distributor,
including, but not limited to, commissions or other payments to such agents
based on the average daily net assets of Fund

                                       23
<PAGE>

shares attributable to their customers. The Distributor may retain any portion
of the total distribution fee payable thereunder to compensate it for
distribution-related services provided by it or to reimburse it for other
distribution-related expenses.

     General.  The Plan will continue in effect from year to year if such
     -------
continuance is approved by a majority vote of both the Trustees of the Trust and
the Non-Interested Trustees.  Any Distribution Agreement related to the Plan
also must be approved by such vote of the Trustees and the Non-Interested
Trustees.  Such Agreement will terminate automatically if assigned, and may be
terminated at any time, without payment of any penalty, by a vote of a majority
of the outstanding voting securities of the relevant class of the Fund or by
vote of a majority of the Non-Interested Trustees on not more than 60 days'
written notice.  The Plan may not be amended to increase materially the amounts
payable thereunder without the approval of a majority of the outstanding voting
securities of the Fund, and no material amendment to the Plan may be made except
by a majority of both the Trustees of the Trust and the Non-Interested Trustees.

     The Plan requires that the Treasurer of Trust shall provide to the
Trustees, and the Trustees shall review, at least quarterly, a written report of
the amounts expended (and purposes therefor) under the Plan. The Rule also
requires that the selection and nomination of Trustees who are not "interested
persons" of the Trust be made by such disinterested Trustees.

     Wells Fargo Bank, an interested person (as that term is defined in Section
2(a)(19) of the 1940 Act) of the Trust, acts as a selling agent for the Funds'
shares pursuant to selling agreements with Stephens authorized under the Plan.
As a selling agent, Wells Fargo Bank has an indirect financial interest in the
operation of the Plan.  The Board of Trustees has concluded that the Plan is
reasonably likely to benefit the Funds and their shareholders because the Plan
authorizes the relationships with selling agents, including Wells Fargo Bank,
that have previously developed distribution channels and relationships with the
retail customers that the Funds are designed to serve.  These relationships and
distribution channels are believed by the Board to provide potential for
increased Fund assets and ultimately corresponding economic efficiencies (i.e.,
lower per-share transaction costs and fixed expenses) that are generated by
increased assets under management.

     Custodian.  Norwest Bank Minnesota, N.A. ("Norwest Bank") acts as Custodian
     ---------
for each Fund.  The Custodian, among other things, maintains a custody account
or accounts in the name of each Fund, receives and delivers all assets for each
Fund upon purchase and upon sale or maturity, collects and receives all income
and other payments and distributions on account of the assets of each Fund, and
pays all expenses of each Fund.  For its services as Custodian, Norwest Bank is
entitled to [RECEIVE A FEE OF 0.02% OF THE AVERAGE DAILY NET ASSETS OF EACH
FUND.]

     FUND ACCOUNTANT.  Forum Financial Services, Inc. acts as Fund Accountant
     ---------------
for the Funds.  The Fund Accountant, among other things, computes net asset
values on a daily basis and performance calculations on a regular basis and as
requested by the Funds.  For providing such services, Forum is entitled to
receive a fee of [___.]

     TRANSFER AND DIVIDEND DISBURSING AGENT.  State Street Bank, acting through
     --------------------------------------
its affiliate Boston Financial Data Services ("BFDS"), acts as Transfer and
Dividend Disbursing Agent for

                                       24
<PAGE>

the Funds. For providing such services, BFDS is entitled to receive a per-
account fee of [0.04% OF THE AVERAGE DAILY NET ASSETS OF EACH SUCH ACCOUNT ON AN
ANNUAL BASIS].

                           PERFORMANCE CALCULATIONS

     The Funds may advertise certain yield and total return information.
Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund or class of shares during the particular time
period shown.  Yield and total return vary based on changes in the market
conditions and the level of a Fund's expenses, and no reported performance
figure should be considered an indication of performance which may be expected
in the future.

     In connection with communicating its performance to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

     Performance information for a Fund may be useful in reviewing the
performance of such Fund and for providing a basis for comparison with
investment alternatives.  The performance of a Fund, however, may not be
comparable to the performance from investment alternatives because of
differences in the foregoing variables and differences in the methods used to
value portfolio securities, compute expenses and calculate performance.

     Performance information may be advertised for non-standardized periods,
including year-to-date and other periods less than a year for the Funds.

     AVERAGE ANNUAL TOTAL RETURN:  The Funds may advertise certain total return
     ---------------------------
information.  As and to the extent required by the SEC, an average annual
compound rate of return ("T") is computed by using the redeemable value at the
end of a specified period ("ERV") of a hypothetical initial investment ("P")
over a period of years ("n") according to the following formula:  P(1+T)n=ERV.

     CUMULATIVE TOTAL RETURN.  In addition to the above performance information,
     -----------------------
each Fund may also advertise the cumulative total return of the Fund.
Cumulative total return is based on the overall percentage change in value of a
hypothetical investment in the Fund, assuming all Fund dividends and capital
gain distributions are reinvested, without reflecting the effect of any sales
charge that would be paid by an investor, and is not annualized.

     YIELD CALCULATIONS:  The Funds may, from time to time, include their yields
     ------------------
and effective yields in advertisements or reports to shareholders or prospective
investors.  Quotations of yield for the Funds are based on the investment income
per share earned during a particular seven-day or thirty-day period, less
expenses accrued during a period ("net investment income") and are computed by
dividing net investment income by the offering price per share on the last date
of the period, according to the following formula:

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

                                       25
<PAGE>

     where a = dividends and interest earned during the period; b = expenses
accrued for the period (net of reimbursements); c = the average daily number of
shares of each Fund outstanding during the period that were entitled to receive
dividends; and d = the maximum offering price per share each Fund share on the
last day of the period.

     EFFECTIVE YIELD:  Effective yields for the Funds are based on the change in
     ---------------
the value of a hypothetical investment (exclusive of capital changes) over a
particular thirty-day period, less a pro-rata share of each Fund's expenses
accrued over that period (the "base period"), and stated as a percentage of the
investment at the start of the base period (the "base period return").  The base
period return is then annualized multiplying by 365/30, with the resulting yield
figure carried to at least the nearest hundredth of one percent.  "Effective
yield" for the Funds assumes that all dividends received during the period have
been reinvested.  Calculation of "effective yield" begins with the same "base
period return" used in the calculation of yield, which is then annualized to
reflect weekly compounding pursuant to the following formula:

         Effective Thirty-Day Yield = [Base Period Return +1)365/30]-1

     Quotations of yield and total return reflect only the performance of a
hypothetical investment in a Fund during the particular time period shown. Yield
and total return vary based on changes in the market conditions and the level of
a Fund's expenses, and no reported performance figure should be considered an
indication of performance which may be expected in the future.  In connection
with communicating its yields or total return to current or prospective
shareholders, these figures may also be compared to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs.

     The yields for each share will fluctuate from time to time, unlike bank
deposits or other investments that pay a fixed yield for a stated period of
time, and do not provide a basis for determining future yields since they are
based on historical data. Yield is a function of portfolio quality, composition,
maturity and market conditions as well as the expenses allocated to a Fund.

     In addition, investors should recognize that changes in the net asset
values of shares of each Fund will affect the yield of the respective class of
shares for any specified period, and such changes should be considered together
with such class' yield in ascertaining such class' total return to shareholders
for the period. Yield information for each class of shares may be useful in
reviewing the performance of the class of shares and for providing a basis for
comparison with investment alternatives. The yield of each class of shares,
however, may not be comparable to the yields from investment alternatives
because of differences in the foregoing variables and differences in the methods
used to value portfolio securities, compute expenses and calculate yield.

     From time to time and only to the extent the comparison is appropriate for
a Fund or a Class of shares, the Trust may quote the performance or price-
earning ratio of a Fund in advertising and other types of literature as compared
with the performance of the S&P Index, the Dow Jones Industrial Average, the
Lehman Brothers 20+ Treasury Index, the Lehman Brothers 5-7 Year Treasury Index,
Donoghue's Money Fund Averages, Real Estate Investment Averages (as reported by
the National Association of Real Estate Investment Trusts), Gold Investment
Averages (provided by the World Gold Council), Bank Averages (which is
calculated from figures supplied

                                       26

by the U.S. League of Savings Institutions based on effective annual rates of
interest on both passbook and certificate accounts), average annualized
certificate of deposit rates (from the Federal Reserve G-13 Statistical Releases
or the Bank Rate Monitor), the Salomon One Year Treasury Benchmark Index, the
Consumer Price Index (as published by the U.S. Bureau of Labor Statistics),
other managed or unmanaged indices or performance data of bonds, municipal
securities, stocks or government securities (including data provided by Ibbotson
Associates), or by other services, companies, publications or persons who
monitor mutual funds on overall performance or other criteria. The S&P Index and
the Dow Jones Industrial Average are unmanaged indices of selected common stock
prices. The performance of a Fund also may be compared to that of other mutual
funds having similar objectives. This comparative performance could be expressed
as a ranking prepared by Lipper Analytical Services, Inc., CDA Investment
Technologies, Inc., Bloomberg Financial Markets or Morningstar, Inc.,
independent services which monitor the performance of mutual funds. The Funds'
performance will be calculated by relating net asset value per share of each
Fund at the beginning of a stated period to the net asset value of the
investment, assuming reinvestment of all gains distributions paid, at the end of
the period. The Funds' comparative performance will be based on a comparison of
yields, as described above, or total return, as reported by Lipper, Survey
Publications, Donoghue or Morningstar, Inc.

     Any such comparisons may be useful to investors who wish to compare past
performance of the Funds with the performance of a Fund's competitors. Of
course, past performance cannot be a guarantee of future results.  The Trust
also may include, from time to time, a reference to certain marketing approaches
of the Distributor, including, for example, a reference to a potential
shareholder being contacted by a selected broker or dealer.  General mutual fund
statistics provided by the Investment Company Institute (the "ICI") may also be
used.

     The Trust also may use the following information in advertisements and
other types of literature, only to the extent the information is appropriate for
each class of shares of a Fund: (i) the Consumer Price Index may be used to
assess the real rate of return from an investment in each class of shares of a
Fund; (ii) other government statistics, including, but not limited to, The
Survey of Current Business, may be used to illustrate investment attributes of
each class of shares of a Fund or the general economic, business, investment, or
financial environment in which a Fund operates; (iii) the effect of tax-deferred
compounding on the investment returns of each class of shares of a Fund or on
returns in general, may be illustrated by graphs, charts, etc., where such
graphs or charts would compare, at various points in time, the return from an
investment in each class of shares of the Fund (or returns in general) on a tax-
deferred basis (assuming reinvestment of capital gains and dividends and
assuming one or more tax rates) with the return on a taxable basis; and (iv) the
sectors or industries in which the Fund invests may be compared to relevant
indices of stocks or surveys (e.g., S&P Industry Surveys) to evaluate the
historical performance or current or potential value of each class of shares of
a Fund with respect to the particular industry or sector.

     The Trust also may use, in advertisements and other types of literature,
information and statements: (1) showing that bank savings accounts offer a
guaranteed return of principal and a fixed rate of interest, but no opportunity
for capital growth; and (2) describing Wells Fargo Bank, and its affiliates and
predecessors, as one of the first investment managers to advise investment
accounts using asset allocation and index strategies.  The Trust also may
include in advertising and other types of literature information and other data
from reports and studies prepared by the Tax

                                       27
<PAGE>

Foundation, including information regarding federal and state tax levels and the
related "Tax Freedom Day."

     The Trust also may discuss in advertising and other types of literature
that a Fund has been assigned a rating by an NRSRO, such as Standard Poor's
Corporation. Such rating would assess the creditworthiness of the investments
held by a Fund.  The assigned rating would not be a recommendation to purchase,
sell or hold a Fund's shares since the rating would not comment on the market
price of a Fund's shares or the suitability of a Fund for a particular investor.
In addition, the assigned rating would be subject to change, suspension or
withdrawal as a result of changes in, or unavailability of, information relating
to a Fund or its investments.  The Trust may compare the performance of each
class of shares of a Fund with other investments which are assigned ratings by
NRSROs. Any such comparisons may be useful to investors who wish to compare each
class' past performance with other rated investments.

     From time to time, a Fund may use the following statements, or variations
thereof, in advertisements and other promotional materials:  "Wells Fargo Bank,
as a Shareholder Servicing Agent for the Wells Fargo Funds Trust, provides
various services to its customers that are also shareholders of the Funds.
These services may include access to Wells Fargo Funds Trust's account
information through Automated Teller Machines (ATMs), the placement of purchase
and redemption requests for shares of the Funds through ATMs and the
availability of combined Wells Fargo Bank and Wells Fargo Funds Trust account
statements."

     The Trust also may disclose, in advertising and other types of literature,
information and statements that Wells Capital Management, Inc., a subsidiary of
Wells Fargo Bank, is listed in the top 100 by Institutional Investor magazine in
                                              ----------------------
its July 1997 survey "America's Top 300 Money Managers." This survey ranks money
managers in several asset categories.  The Trust also may disclose in
advertising and other types of sales literature the assets and categories of
assets under management by the Trust's Advisor and the total amount of assets
and mutual fund assets managed by Wells Fargo Bank.  As of December 31, 1998,
Wells Fargo Bank and its affiliates managed over $202 billion in assets.

     The Trust may disclose in advertising and other types of literature that
investors can open and maintain Sweep Accounts over the Internet or through
other electronic channels (collectively, "Electronic Channels"). Such
advertising and other literature may discuss the investment options available to
investors, including the types of accounts and any applicable fees. Such
advertising and other literature may disclose that Wells Fargo Bank is the first
major bank to offer an on-line application for a mutual fund account that can be
filled out completely through Electronic Channels. Advertising and other
literature may disclose that Wells Fargo Bank may maintain Web sites, pages or
other information sites accessible through Electronic Channels (an "Information
Site") and may describe the contents and features of the Information Site and
instruct investors on how to access the Information Site and open a Sweep
Account. Advertising and other literature may also disclose the procedures
employed by Wells Fargo Bank to secure information provided by investors,
including disclosure and discussion of the tools and services for accessing
Electronic Channels. Such advertising or other literature may include
discussions of the advantages of establishing and maintaining a Sweep Account
through Electronic Channels and testimonials from Wells Fargo Bank customers or
employees and may also include descriptions of locations where

                                       28
<PAGE>

product demonstrations may occur. The Trust may also disclose the ranking of
Wells Fargo Bank as one of the largest money managers in the United States.

                       DETERMINATION OF NET ASSET VALUE

     Net asset value per share for each Fund is determined as of the close of
regular trading (currently 1:00 p.m., Pacific time/3:00 p.m. Central time) on
each day the New York Stock Exchange ("NYSE") is open for business.  Expenses
and fees, including advisory fees, are accrued daily and are taken into account
for the purpose of determining the net asset value of the Funds' shares.

     Securities of a Fund for which market quotations are available are valued
at latest prices.  Any security for which the primary market is an exchange is
valued at the last sale price on such exchange on the day of valuation or, if
there was no sale on such day, the latest bid price quoted on such day.  In the
case of other Fund securities, including U.S. Government securities but
excluding money market instruments and debt securities maturing in 60 days or
less, the valuations are based on latest quoted bid prices.  Money market
instruments and debt securities maturing in 60 days or less are valued at
amortized cost.  Futures contracts will be marked to market daily at their
respective settlement prices determined by the relevant exchange.  Prices may be
furnished by a reputable independent pricing service approved by the Trust's
Board of Trustees.  Prices provided by an independent pricing service may be
determined without exclusive reliance on quoted prices and may take into account
appropriate factors such as institutional-size trading in similar groups of
securities, yield, quality, coupon rate, maturity, type of issue, trading
characteristics and other market data.  All other securities and other assets of
a Fund for which current market quotations are not readily available are valued
at fair value as determined in good faith by the Trust's Board of Trustees and
in accordance with procedures adopted by the  Trustees.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

     Shares of the Funds may be purchased on any day the Funds are open for
business.  Each Fund is open for business each day the NYSE is open for trading
(a "Business Day"). Currently, the NYSE is closed 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 a "Holiday"). When any
Holiday falls on a weekend, the NYSE typically is closed on the weekday
immediately before or after such Holiday.

     Payment for shares may, in the discretion of the Advisor, be made in the
form of securities that are permissible investments for the Funds.  For further
information about this form of payment please contact Stephens. In connection
with an in-kind securities payment, the Funds will require, among other things,
that the securities be valued on the day of purchase in accordance with the
pricing methods used by a Fund and that such Fund receives satisfactory
assurances that (i) it will have good and marketable title to the securities
received by it; (ii) that the securities are in proper form for transfer to the
Fund; and (iii) adequate information will be provided concerning the basis and
other matters relating to the securities.

     Under the 1940 Act, the Funds may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the
NYSE is closed (other than customary

                                       29
<PAGE>

weekend and holiday closings, or during which trading is restricted, or during
which as determined by the SEC by rule or regulation) an emergency exists as a
result of which disposal or valuation of portfolio securities is not reasonably
practicable, or for such periods as the SEC may permit. The Trust may also
redeem shares involuntarily or make payment for redemption in securities or
other property if it appears appropriate to do so in light of the Trust's
responsibilities under the 1940 Act. In addition, the Trust may redeem shares
involuntarily to reimburse the Fund for any losses sustained by reason of the
failure of a shareholder to make full payment for shares purchased or to collect
any charge relating to a transaction effected for the benefit of a shareholder
which is applicable to shares of a Fund as provided from time to time in the
Prospectus.

                            PORTFOLIO TRANSACTIONS

     The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities.  Subject to policies
established by the Trust's Board of Trustees, Wells Fargo Bank is responsible
for each Fund's portfolio decisions and the placing of portfolio transactions.
In placing orders, it is the policy of the Trust to obtain the best results
taking into account the dealer's general execution and operational facilities,
the type of transaction involved and other factors such as the dealer's risk in
positioning the securities involved.  While Wells Fargo Bank generally seeks
reasonably competitive spreads or commissions, the Funds will not necessarily be
paying the lowest spread or commission available.

     Purchases and sales of non-equity securities usually will be principal
transactions.  Portfolio securities normally will be purchased or sold from or
to dealers serving as market makers for the securities at a net price.  Each of
the Funds also will purchase portfolio securities in underwritten offerings and
may purchase securities directly from the issuer.  Generally, municipal
obligations and taxable money market securities are traded on a net basis and do
not involve brokerage commissions.  The cost of executing a Fund's portfolio
securities transactions will consist primarily of dealer spreads and
underwriting commissions.  Under the 1940 Act, persons affiliated with the Trust
are prohibited from dealing with the Trust as a principal in the purchase and
sale of securities unless an exemptive order allowing such transactions is
obtained from the SEC or an exemption is otherwise available.  The Fund may
purchase securities from underwriting syndicates of which Stephens or Wells
Fargo Bank is a member under certain conditions in accordance with the
provisions of a rule adopted under the 1940 Act and in compliance with
procedures adopted by the Board of Trustees.

     Wells Fargo Bank, as the Investment Advisor to the Funds, may, in
circumstances in which two or more dealers are in a position to offer comparable
results for a Fund portfolio transaction, give preference to a dealer that has
provided statistical or other research services to Wells Fargo Bank.  By
allocating transactions in this manner, Wells Fargo Bank is able to supplement
its research and analysis with the views and information of securities firms.
Information so received will be in addition to, and not in lieu of, the services
required to be performed by Wells Fargo Bank under the Advisory Contracts, and
the expenses of Wells Fargo Bank will not necessarily be reduced as a result of
the receipt of this supplemental research information.  Furthermore, research
services furnished by dealers through which Wells Fargo Bank places securities
transactions for a Fund may be used by Wells Fargo Bank in servicing its

                                       30
<PAGE>

other accounts, and not all of these services may be used by Wells Fargo Bank in
connection with advising the Funds.

     Portfolio Turnover.  The portfolio turnover rate is not a limiting factor
     ------------------
when Wells Fargo Bank deems portfolio changes appropriate.  Changes may be made
in the portfolios consistent with the investment objectives and policies of the
Funds whenever such changes are believed to be in the best interests of the
Funds and their shareholders. The portfolio turnover rate is calculated by
dividing the lesser of purchases or sales of portfolio securities by the average
monthly value of the Fund's portfolio securities. For purposes of this
calculation, portfolio securities exclude all securities having a maturity when
purchased of one year or less.  Portfolio turnover generally involves some
expenses to the Funds, including brokerage commissions or dealer mark-ups and
other transaction costs on the sale of securities and the reinvestment in other
securities.  Portfolio turnover also can generate short-term capital gain tax
consequences.  Portfolio turnover rate is not a limiting factor when Wells Fargo
Bank deems portfolio changes appropriate.

                                 FUND EXPENSES

     From time to time, Wells Fargo Bank and Stephens may waive fees from the
Funds in whole or in part.  Any such waiver will reduce expenses and,
accordingly, have a favorable impact on a Fund's performance.

     Except for the expenses borne by Wells Fargo Bank and Stephens, the Trust
bears all costs of its operations, including the compensation of its Trustees
who are not affiliated with Stephens or Wells Fargo Bank or any of their
affiliates; advisory, shareholder servicing and administration fees; payments
pursuant to any Plan; interest charges; taxes; fees and expenses of its
independent auditors, legal counsel, transfer agent and dividend disbursing
agent; expenses of redeeming shares; expenses of preparing and printing
Prospectuses (except the expense of printing and mailing Prospectuses used for
promotional purposes, unless otherwise payable pursuant to a Plan),
shareholders' reports, notices, proxy statements and reports to regulatory
agencies; insurance premiums and certain expenses relating to insurance
coverage; trade association membership dues; brokerage and other expenses
connected with the execution of portfolio transactions; fees and expenses of its
custodian, including those for keeping books and accounts and calculating the
net asset value per share of a Fund; expenses of shareholders' meetings;
expenses relating to the issuance, registration and qualification of a Fund's
shares; and pricing services, organizational expenses and any extraordinary
expenses. Expenses attributable to the Fund are charged against Fund assets.
General expenses of the Trust are allocated among all of the funds of the Trust,
including the Funds, in a manner proportionate to the net assets of each Fund,
on a transactional basis, or on such other basis as the Trust's Board of
Trustees deems equitable.

                              FEDERAL INCOME TAXES

     The following information supplements and should be read in conjunction
with the Prospectus section entitled "Taxes."  The Prospectus of the Funds
describe generally the tax treatment of distributions by the Funds.  This
section of the SAI includes additional information concerning federal income
taxes.

                                       31
<PAGE>

     General.  The Trust intends to qualify each Fund as a regulated investment
     -------
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"), as long as such qualification is in the best interest of the Fund's
shareholders.  Each Fund will be treated as a separate entity for federal income
tax purposes.  Thus, the provisions of the Code applicable to regulated
investment companies generally will be applied to each Fund, rather than to the
Trust as a whole.  In addition, net capital gains, net investment income, and
operating expenses will be determined separately for each Fund.  As a regulated
investment company, each Fund will not be taxed on its net investment income and
capital gains distributed to its shareholders.

     Qualification as a regulated investment company under the Code requires,
among other things, that each Fund (a) derive at least 90% of its annual gross
income from dividends, interest, certain payments with respect to securities
loans, gains from the sale or other disposition of stock or securities or
foreign currencies (to the extent such currency gains are directly related to
the regulated investment company's principal business of investing in stock or
securities) and other income (including, but not limited to, gains from options,
futures or forward contracts) derived with respect to its business of investing
in such stock, securities or currencies; and (b) diversify its holdings so that,
at the end of each quarter of the taxable year, (i) at least 50% of the market
value of the Fund's assets is represented by cash, government securities and
other securities limited with respect to any one issuer to an amount not greater
than 5% of the Fund's assets and 10% of the outstanding voting securities of
such issuer, and (ii) not more than 25% of the value of its assets is invested
in the securities of any one issuer (other than U.S. Government obligations and
the securities of other regulated investment companies), or in two or more
issuers which the Fund controls and which are determined to be engaged in the
same or similar trades or businesses.

     The Funds also must distribute or be deemed to distribute to their
shareholders at least 90% of their net investment income (which, for this
purpose, includes net short-term capital gains) earned in each taxable year.  In
general, these distributions must actually or be deemed to be made in the
taxable year.  However, in certain circumstances, such distributions may be made
in the 12 months following the taxable year.  Furthermore, distributions
declared in October, November or December of one taxable year and paid by
January 31 of the following taxable year will be treated as paid by December 31
of the first taxable year.  The Funds intend to pay out substantially all of
their net investment income and net realized capital gains (if any) for each
year.

     Excise Tax.  A 4% nondeductible excise tax will be imposed on each Fund
     ----------
(other than to the extent of its tax-exempt interest income) to the extent it
does not meet certain minimum distribution requirements by the end of each
calendar year.  Each Fund intends to actually or be deemed to distribute
substantially all of its net investment income and net capital gains by the end
of each calendar year and, thus, expects not to be subject to the excise tax.

     Taxation of Fund Investments.  Except as provided herein, gains and losses
     ----------------------------
on the sale of portfolio securities by a Fund will generally be capital gains
and losses.  Such gains and losses will ordinarily be long-term capital gains
and losses if the securities have been held by the Fund for more than one year
at the time of disposition of the securities.

                                       32
<PAGE>

     Gains recognized on the disposition of a debt obligation (including tax-
exempt obligations purchased after April 30, 1993) purchased by a Fund at a
market discount (generally at a price less than its principal amount) will be
treated as ordinary income to the extent of the portion of market discount which
accrued, but was not previously recognized pursuant to an available election,
during the term the Fund held the debt obligation.

     If an option granted by a Fund lapses or is terminated through a closing
transaction, such as a repurchase by the Fund of the option from its holder, the
Fund will realize a short-term capital gain or loss, depending on whether the
premium income is greater or less than the amount paid by the Fund in the
closing transaction.  Some realized capital losses may be deferred if they
result from a position which is part of a "straddle," discussed below.  If
securities are sold by the Fund pursuant to the exercise of a call option
written by it, the Fund will add the premium received to the sale price of the
securities delivered in determining the amount of gain or loss on the sale.  If
securities are purchased by a Fund pursuant to the exercise of a put option
written by it, such Fund will subtract the premium received from its cost basis
in the securities purchased.

     The amount of any gain or loss realized by a Fund on closing out a
regulated futures contract will generally result in a realized capital gain or
loss for federal income tax purposes. Regulated futures contracts held at the
end of each fiscal year will be required to be "marked to market" for federal
income tax purposes pursuant to Section 1256 of the Code.  In this regard, they
will be deemed to have been sold at market value. Sixty percent (60%) of any net
gain or loss recognized on these deemed sales, and sixty percent (60%) of any
net realized gain or loss from any actual sales, will generally be treated as
long-term capital gain or loss, and the remainder will be treated as short-term
capital gain or loss.  Transactions that qualify as designated hedges are
excepted from the "mark-to-market" rule and the "60%/40%" rule.

     Under Section 988 of the Code, a Fund generally will recognize ordinary
income or loss to the extent that gain or loss realized on the disposition of
portfolio securities is attributable to changes in foreign currency exchange
rates.  In addition, gain or loss realized on the disposition of a foreign
currency forward contract, futures contract, option or similar financial
instrument, or of foreign currency itself, will generally be treated as ordinary
income or loss.  The Funds will attempt to monitor Section 988 transactions,
where applicable, to avoid adverse Federal income tax impact.

     Offsetting positions held by a Fund involving certain financial forward,
futures or options contracts may be considered, for tax purposes, to constitute
"straddles."  "Straddles" are defined to include "offsetting positions" in
actively traded personal property.  The tax treatment of "straddles" is governed
by Section 1092 of the Code which, in certain circumstances, overrides or
modifies the provisions of Section 1256.  If a Fund were treated as entering
into "straddles" by engaging in certain financial forward, futures or option
contracts, such straddles could be characterized as "mixed straddles" if the
futures, forwards, or options comprising a part of such straddles were governed
by Section 1256 of the Code.  The Fund may make one or more elections with
respect to "mixed straddles."  Depending upon which election is made, if any,
the results with respect to the Fund may differ.  Generally, to the extent the
straddle rules apply to positions established by the Fund, losses realized by
the Fund may be deferred to the extent of unrealized gain in any offsetting
positions.  Moreover, as a result of the straddle and the conversion transaction
rules, short-term capital loss on straddle positions may be recharacterized

                                       33
<PAGE>

as long-term capital loss, and long-term capital gain may be characterized as
short-term capital gain or ordinary income.

     If a Fund enters into a "constructive sale" of any appreciated position in
stock, a partnership interest, or certain debt instruments, the Fund must
recognize gain (but not loss) with respect to that position.  For this purpose,
a constructive sale occurs when the Fund enters into one of the following
transactions with respect to the same or substantially identical property: (i) a
short sale; (ii) an offsetting notional principal contract; or (iii) a futures
or forward contract.

     Income and dividends received by the Funds from sources within foreign
countries may be subject to withholding and other taxes imposed by such
countries.

     Capital Gain Distributions.  Distributions which are designated by a Fund
     --------------------------
as capital gain distributions will be taxed to shareholders as long-term term
capital gain (to the extent such dividends do exceed the Fund's actual net
capital gains for the taxable year), regardless of how long a shareholder has
held Fund shares.  Such distributions will be designated as capital gain
distributions in a written notice mailed by the Fund to its shareholders not
later than 60 days after the close of the Fund's taxable year.

     Disposition of Fund Shares.  A disposition of Fund shares pursuant to a
     --------------------------
redemption (including a redemption in-kind) or an exchange will ordinarily
result in a taxable capital gain or loss, depending on the amount received for
the shares (or are deemed to be received in the case of an exchange) and the
cost of the shares.

     If a shareholder exchanges or otherwise disposes of Fund shares within 90
days of having acquired such shares and if, as a result of having acquired those
shares, the shareholder subsequently pays a reduced sales charge on a new
purchase of shares of the Fund or a different regulated investment company, the
sales charge previously incurred in acquiring the Fund's shares shall not be
taken into account (to the extent such previous sales charges do not exceed the
reduction in sales charges on the new purchase) for the purpose of determining
the amount of gain or loss on the disposition, but will be treated as having
been incurred in the acquisition of such other shares.  Also, any loss realized
on a redemption or exchange of shares of the Fund will be disallowed to the
extent that substantially identical shares are acquired within the 61-day period
beginning 30 days before and ending 30 days after the shares are disposed of.

     If a shareholder receives a designated capital gain distribution (to be
treated by the shareholder as a long-term capital gain) with respect to any Fund
share and such Fund share is held for six months or less, then (unless otherwise
disallowed) any loss on the sale or exchange of that Fund share will be treated
as a long-term capital loss to the extent of the designated capital gain
distribution.  In addition, if a shareholder holds Fund shares for six months or
less, any loss on the sale or exchange of those shares will be disallowed to the
extent of the amount of exempt-interest dividends received with respect to the
shares.  The Treasury Department is authorized to issue regulations reducing the
six months holding requirement to a period of not less than the greater of 31
days or the period between regular dividend distributions where a Fund regularly
distributes at least 90% of its net tax-exempt interest, if any.  No such
regulations have been issued as of the date of this SAI.  The loss disallowance
rules described in this paragraph do not apply to losses realized under a
periodic redemption plan.

     Federal Income Tax Rates.  As of the printing of this SAI, the maximum
     ------------------------
individual tax rate applicable to ordinary income is 39.6% (marginal tax rates
may be higher for some individuals to reduce or eliminate the benefit of
exemptions and deductions); the maximum individual marginal tax rate applicable
to net capital gain is 20%; and the maximum corporate tax rate applicable to
ordinary income and net capital gain is 35% (marginal tax rates may be higher
for some corporations to reduce or eliminate the benefit of lower marginal
income tax rates).  Naturally, the amount of tax payable by an individual or
corporation will be affected by a combination of tax laws covering, for example,
deductions, credits, deferrals, exemptions, sources of income and other matters.

     Backup Withholding.  The Trustees may be required to withhold, subject to
     ------------------
certain exemptions, at a rate of 31% ("backup withholding") on dividends,
capital gain distributions, and redemption proceeds (including proceeds from
exchanges and redemptions in-kind) paid or credited to an individual Fund
shareholder, if the shareholder fails to certify that the Taxpayer
Identification Number ("TIN") provided is correct and that the shareholder is
not subject to backup withholding, or if the IRS notifies the Trust that the
shareholder's TIN is incorrect or that the shareholder is subject to backup
withholding.  Such tax withheld does not constitute any additional tax imposed
on the shareholder, and may be claimed as a tax payment on the shareholder's
federal income tax return.  An investor must provide a valid TIN upon opening or
reopening an account.  Failure to furnish a valid TIN to the Trust could also
subject the investor to penalties imposed by the IRS.

     Corporate Shareholders.  Corporate shareholders of the Funds may be
     ----------------------
eligible for the dividends-received deduction on dividends distributed out of a
Fund's net investment income attributable to dividends received from domestic
corporations, which, if received directly by the corporate shareholder, would
qualify for such deduction.  A distribution by a Fund attributable to dividends
of a domestic corporation will only qualify for the dividends-received deduction
if (i) the corporate shareholder generally holds the Fund shares upon which the
distribution is made for at least 46 days during the 90 day period beginning 45
days prior to the date upon which the shareholder becomes entitled to the
distribution; and (ii) the Fund generally holds the shares of the domestic
corporation producing the dividend income for at least 46 days during the 90 day
period beginning 45 days prior to the date upon which the Fund becomes entitled
to such dividend income.

     Foreign Shareholders.  Under the Code, distributions of net investment
     --------------------
income by the Funds to a nonresident alien individual, foreign trust (i.e.,
trust which a U.S. court is able to exercise primary supervision over
administration of that trust and one or more U.S. persons have authority to
control substantial decisions of that trust), foreign estate (i.e., the income
of which is not subject to U.S. tax regardless of source), foreign corporation,
or foreign partnership (a "foreign shareholder") will be subject to U.S.
withholding tax (at a rate of 30% or a lower treaty rate, if applicable).
Withholding will not apply if a dividend paid by the Fund to a foreign
shareholder is "effectively connected" with a U.S. trade or business (or, if an
income tax treaty applies, is attributable to a U.S. permanent establishment of
the foreign shareholder), in which case the reporting and withholding
requirements applicable to U.S. persons will apply.  Distributions of net long-
term capital gains are generally not subject to tax withholding.

                                       35
<PAGE>

     New Regulations.  On October 6, 1997, the Treasury Department issued new
     ---------------
regulations (the "New Regulations") which make certain modifications to the
backup withholding, U.S. income tax withholding and information reporting rules
applicable to foreign shareholders.  The New Regulations will generally be
effective for payments made after December 31, 1999, subject to certain
transition rules.  Among other things, the New Regulations will permit the Funds
to estimate the portion of their distributions qualifying as capital gain
distributions for purposes of determining the portion of such distributions paid
to foreign shareholders that will be subject to U.S. income tax withholding.
Prospective investors are urged to consult their own tax advisors regarding the
New Regulations.

     Tax-Deferred Plan.  The shares of the Funds are available for a variety of
     -----------------
tax-deferred retirement and other plans, including Individual Retirement
Accounts ("IRA"), Simplified Employee Pension Plans ("SEP-IRA"), Savings
Incentive Match Plans for Employees ("SIMPLE plans"), Roth IRAs, and Education
IRAs, which permit investors to defer some of their income from taxes.
Investors should contact their selling agents for details concerning retirement
plans.

     Other Matters.  Investors should be aware that the investments to be made
     -------------
by the Funds may involve sophisticated tax rules that may result in income or
gain recognition by the Funds without corresponding current cash receipts.
Although the Funds will seek to avoid significant noncash income, such noncash
income could be recognized by the Funds, in which case the Funds may distribute
cash derived from other sources in order to meet the minimum distribution
requirements described above.

     The foregoing discussion and the discussions in the Prospectus applicable
to each shareholder address only some of the Federal tax considerations
generally affecting investments in the Funds.  Each investor is urged to consult
his or her tax advisor regarding specific questions as to federal, state, local
or foreign taxes.

                                 CAPITAL STOCK

     The Funds are three of the funds in the Wells Fargo Funds Trust family of
funds.  The Trust was organized as a Delaware business trust on March 10, 1999.

     Most of the Trust's funds are authorized to issue multiple classes of
shares, one class generally subject to a front-end sales charge and, in some
cases, classes subject to a contingent-deferred sales charge, that are offered
to retail investors.  Certain of the Trust's funds also are authorized to issue
other classes of shares, which are sold primarily to institutional investors.
Each class of shares in a fund represents an equal, proportionate interest in a
fund with other shares of the same class.  Shareholders of each class bear their
pro rata portion of the fund's operating expenses, except for certain class-
specific expenses (e.g., any state securities registration fees, shareholder
servicing fees or distribution fees that may be paid under Rule 12b-1) that are
allocated to a particular class.  Please contact Shareholder Services at 1-800-
260-5969 if you would like additional information about other funds or classes
of shares offered by the Trust.

     With respect to matters affecting one class but not another, shareholders
vote as a class; for example, the approval of a Plan.  Subject to the foregoing,
all shares of a Fund have equal

                                       36
<PAGE>

voting rights and will be voted in the aggregate, and not by series, except
where voting by a series is required by law or where the matter involved only
affects one series. For example, a change in a Fund's fundamental investment
policy affects only one series and would be voted upon only by shareholders of
the Fund involved. Additionally, approval of an advisory contract, since it
affects only one Fund, is a matter to be determined separately by Series.
Approval by the shareholders of one Series is effective as to that Series
whether or not sufficient votes are received from the shareholders of the other
Series to approve the proposal as to those Series.

     As used in the Prospectus and in this SAI, the term "majority," when
referring to approvals to be obtained from shareholders of a Class of shares of
a Fund, means the vote of the lesser of (i) 67% of the shares of the Class
represented at a meeting if the holders of more than 50% of the outstanding
shares of the Class are present in person or by proxy, or (ii) more than 50% of
the outstanding shares of the Class of the Fund.  The term "majority," when
referring to approvals to be obtained from shareholders of the Fund, means the
vote of the lesser of (i) 67% of the shares of the Fund represented at a meeting
if the holders of more than 50% of the outstanding shares of the Fund are
present in person or by proxy, or (ii) more than 50% of the outstanding shares
of the Fund.  The term "majority," when referring to the approvals to be
obtained from shareholders of the Trust as a whole, means the vote of the lesser
of (i) 67% of the Trust's shares represented at a meeting if the holders of more
than 50% of the Trust's outstanding shares are present in person or by proxy, or
(ii) more than 50% of the Trust's outstanding shares.

     Shareholders are not entitled to any preemptive rights. All shares, when
issued, will be fully paid and non-assessable by the Trust.  The Trust may
dispense with an annual meeting of shareholders in any year in which it is not
required to elect Trustees under the 1940 Act.

     Each share of a class of a Fund represents an equal proportional interest
in the Fund with each other share of the same class and is entitled to such
dividends and distributions out of the income earned on the assets belonging to
the Fund as are declared in the discretion of the Trustees. In the event of the
liquidation or dissolution of the Trust, shareholders of a Fund are entitled to
receive the assets attributable to that Fund that are available for
distribution, and a distribution of any general assets not attributable to a
particular Fund or portfolio that are available for distribution in such manner
and on such basis as the Trustees in their sole discretion may determine.

     Set forth below, [as of May 25, 1999, ]is the name, address and share
ownership of each person known by the Trust to have beneficial or record
ownership of 5% or more of a class of a Fund or 5% or more of the voting
securities as a whole.  The term "N/A" is used where a shareholder holds 5% or
more of a class, but less than 5% of a Fund as a whole.

     For purposes of the 1940 Act, any person who owns directly or through one
or more controlled companies more than 25% of the voting securities of a company
is presumed to "control" such company. Accordingly, to the extent that a
shareholder identified in the foregoing table is identified as the beneficial
holder of more than 25% of a class (or Fund), or is identified as the holder of
record of more than 25% of a class (or Fund) and has voting and/or investment
powers, it may be presumed to control such class (or Fund).

                                   APPENDIX

     The following is a description of the ratings given by Moody's and S&P to
corporate and municipal bonds, municipal notes, and corporate and municipal
commercial paper.

     Corporate Bonds

     Moody's:  The four highest ratings for corporate bonds are "Aaa," "Aa," "A"
and "Baa." Bonds rated "Aaa" are judged to be of the "best quality" and carry
the smallest amount of investment risk. Bonds rated "Aa" are of "high quality by
all standards," but margins of protection or other elements make long-term risks
appear somewhat greater than "Aaa" rated bonds. Bonds rated "A" possess many
favorable investment attributes and are considered to be upper medium grade
obligations. Bonds rated "Baa" are considered to be medium grade obligations;
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. Moody's
also applies numerical modifiers in its rating system: 1, 2 and 3 in each rating
category from "Aa" through "Baa" in its rating system. The modifier 1 indicates
that the security ranks in the higher end of its category; the modifier 2
indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks
in the lower end.

     S&P:  The four highest ratings for corporate and municipal bonds are "AAA,"
"AA," "A" and "BBB." Bonds rated "AAA" have the "highest rating" assigned by S&P
and have "an extremely strong capacity" to pay interest and repay principal.
Bonds rated "AA" have a "very strong capacity" to pay interest and repay
principal and "differ from the highest rated obligations only in small degree."
Bonds rated "A" have a "strong capacity" to pay interest and repay principal,
but are "somewhat more susceptible" to adverse effects of changes in economic
conditions or other circumstances than bonds in higher rated categories. Bonds
rated "BBB" are regarded as having "adequate protection parameters" to pay
interest and repay principal, but changes in economic conditions or other
circumstances are more likely to lead to a "weakened capacity" to make such
repayments. The ratings from "AA" to "BBB" may be modified by the addition of a
plus or minus sign to show relative standing within the category.

     Commercial Paper

     Moody's:  The highest rating for commercial paper is "P-1" (Prime-1).
Issuers rated "P-1" have a "superior ability for repayment of senior short-term
debt obligations." Issuers rated "P-2" (Prime-2) "have a strong capacity for
repayment of senior short-term debt obligations," but earnings trends, while
sound, will be subject to more variation.

     S&P:  The "A-1" rating for commercial paper is rated "in the highest
category" by S&P and "the obligor's capacity to meet its financial commitment on
the obligation is strong." The "A-1+" rating indicates that said capacity is
"extremely strong." The A-2 rating indicates that said capacity is
"satisfactory," but that corporate and municipal

                                      A-1
<PAGE>

commercial paper rated "A-2" is "more susceptible" to the adverse effects of
changes in economic conditions or other circumstances than commercial paper
rated in higher rating categories.

       Re:  Shares of Common Stock of
            Wells Fargo Funds Trust
            -----------------------

Ladies/Gentlemen:

       We refer to the Registration Statement on Form N-1A (SEC File Nos. 333-
74295 and 811-09253) (the "Registration Statement") of Wells Fargo Funds Trust
(the "Trust") relating to the registration of an indefinite number of shares of
common stock of the Trust (collectively, the "Shares").

       We have been requested by the Trust to furnish this opinion as Exhibit
(i) to the Registration Statement.

       We have examined documents relating to the organization of the Trust and
its series and the authorization and issuance of shares of its series.

       Based upon and subject to the foregoing, we are of the opinion that:

       The issuance and sale of the Shares by the Trust, upon completion of such
corporate action as is deemed necessary or appropriate, will be duly and validly
authorized by such corporate action and assuming delivery by sale or in accord
with the Trust's dividend reinvestment plan in accordance with the description
set forth in the Fund's current prospectus under the Securities Act of 1933, as
amended, the Shares will be legally issued, fully paid and nonassessable by the
Trust.

<PAGE>

       We consent to the inclusion of this opinion as an exhibit to the
Registration Statement.

       In addition, we hereby consent to the use of our name and to the
reference to the description of advice rendered by our firm under the heading
"Counsel" in the Statements of Additional Information, which are included as
part of the Registration Statement.


                              Very truly yours,

                              /s/ MORRISON & FOERSTER LLP
