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 __. 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. Although the money market funds seek
to preserve the value of your investment at $1.00 per share, it is possible to 
lose money by investing in these funds.

- --------------------------------------------------------------------------------
COMMON RISKS FOR THE FUNDS
- --------------------------------------------------------------------------------

EQUITY SECURITIES. The equity and allocation 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 investments 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 Asset Allocation Fund, the income funds and the money
market 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. The equity funds may
invest some of their assets in debt securities.

- --------------------------------------------------------------------------------
FUND                   SPECIFIC RISKS
- --------------------------------------------------------------------------------

EQUITY AND 
ALLOCATION 
FUNDS
- --------------------------------------------------------------------------------

ASSET ALLOCATION FUND  This Fund uses an investment model that 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 FUND            This Fund is primarily subject to the equity securities
                       risks described in the Common Risks section, above.
- --------------------------------------------------------------------------------

INCOME EQUITY FUND     Stocks selected for their high dividend income may be 
                       more sensitive to interest rate changes than other
                       stocks. This Fund is primarily subject to the equity
                       securities risks described in the Common Risks section,
                       above.
- --------------------------------------------------------------------------------

SMALL CAP FUND         This Fund may invest in companies that pay low or no
                       dividends, have smaller market capitalizations, have less
                       market liquidity, have no or relatively short operating
                       histories, or are newly public companies.  Some of these
                       companies have aggressive capital structures, including
                       high debt levels, or are involved in rapidly growing or
                       changing industries and/or new technologies. Because the
                       Fund 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.
- --------------------------------------------------------------------------------
INCOME FUNDS 
- --------------------------------------------------------------------------------

INCOME FUND            This Fund is primarily subject to the debt securities 
                       risks described in the Common Risks section above.

TAX-FREE INCOME               Some of this Fund's investments are subject to
  FUND                        federal income and AMT taxes, so you may incur a
                              tax liability on an investment in this Fund.
                              Municipal obligations backed by tax revenues of
                              the issuer's jurisdiction could be adversely
                              affected if the issuer cannot raise adequate
                              revenues to meet its obligations.

ASSET ALLOCATION FUND
 
INVESTMENT OBJECTIVE
The Asset Allocation Fund seeks long-term total return, consistent with
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                                                  
The asset classes we invest in are:                                    
                                                                       
 .    Stock Investments -- We invest in common stocks representative of the S&P
     500 Index. We do not individually select common stocks on the basis of
     traditional investment analysis. Instead, stock investments are made
     according to a weighted formula intended to match the total return 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 in this Index have remaining
     maturities of twenty 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 may invest:
 
 .    In call and put options on stock indexes, stock index futures, options on
     stock index futures, and interest rate futures contracts as a substitute
     for a comparable market position in stocks or bonds;

 .    In interest rate and index swaps; and

 .    Up to 25% of total assets in foreign obligations qualifying as money market
     investments.
      
We manage the allocation of investments in the Fund's portfolio assuming a
"normal" allocation of 60% stocks and 40% bonds. This is not a "target"
allocation but rather is a design feature that is intended to set a level of
risk tolerance for the Fund.

We are not required to keep a minimum investment in any of the three asset
classes described above, nor are we prohibited from investing substantially all
of our assets in a single class. The allocation may shift at any time.

IMPORTANT RISK FACTORS                                    
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.

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

GROWTH FUND
 
INVESTMENT OBJECTIVE
The Growth Fund seeks long-term capital appreciation.                  
                                                                       
INVESTMENT POLICIES                                                    
We seek long-term capital appreciation by investing primarily in common stocks
and other equity securities and we look for companies that have a strong
earnings growth trend that we believe have above-average prospects for future
growth. 
 
PERMITTED INVESTMENTS
Under normal market conditions, we invest:
 
 .    at least 65% of our total assets in equity securities, including common and
     preferred stocks, and securities convertible into common stocks;

 .    the majority of our total assets in issues of companies with market
     capitalization that falls within the range of the Russell 1000 Index (As of
     [MARCH 31, 1999,] this range was from [$____ MILLION TO $____ BILLION.] The
     range is expected to change frequently.);

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

 .    up to 15% of our total assets in emerging markets.
 
IMPORTANT RISK FACTORS
This Fund is primarily subject to the equity market risks described in the
Common Risks section.
 
You should consider the Common Risks on page ___, and the General Investment
Risks beginning on page ___. They are all important to your investment choice.

INCOME EQUITY FUND
 
INVESTMENT OBJECTIVE                                                   
The Income Equity Fund seeks long-term capital appreciation and above-average
dividend income.

INVESTMENT POLICIES                                                    
We invest primarily in the common stock of large, high-quality domestic
companies that have above-average return potential based on current market
valuations. We primarily emphasize investments in securities of companies with
above-average dividend income. We use various valuation measures when selecting
securities for the portfolio, including above-average dividend yields and below
industry average price-to-earnings, price-to-book and price-to-sales ratios. We
consider large companies to be those whose market capitalization is greater than
the median of the Russell 1000 Index.

PERMITTED INVESTMENTS                                                  
Under normal market conditions, we invest:                             
                                                                       
 .    at least 65% of our total assets in equity securities; and

 .    in issues of companies with market capitalization greater than the median
     of the Russell 1000 Index (as of March 31, 1999, this median was [$____
     BILLION;] the range is expected to change frequently).

We may invest in preferred stocks, convertible securities, and securities of
foreign companies. We will normally limit our investment in a single issuer to
10% or less of our total assets.
 
IMPORTANT RISK FACTORS
Stocks selected for their high dividend yields may be more sensitive to interest
rate changes than other stocks. 

You should consider the Common Risks on page ___, the General Investment Risks
beginning on page ___ and the specific risks listed here. They are all important
to your investment choice.
 
CORE/GATEWAY ARRANGEMENT                                   
The Income Equity Fund is a "gateway" fund in a "core/gateway" arrangement. In
this arrangement, 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 Income Equity Fund also
refer to the core portfolio.

PORTFOLIO MANAGERS                                        
 .    DAVID L. ROBERTS, CFA

     years of investment management experience.

 .    GARY J. DUNN, CFA

     from NIM, where he had managed portfolios for NIM or its affiliates since
     1979. He has approximately twenty years of investment management
     experience.

INVESTMENT POLICIES                                                    
We actively manage a diversified portfolio of common stocks issued by companies
whose market capitalization falls within the range of the Russell 2000 Index. As
of March 31, 1999, the range was [$___ MILLION TO $____ BILLION,] but it is
expected to change frequently. We will sell the stock of any company whose
market capitalization exceeds the range of this index for sixty consecutive
days.                                                                       

We invest in the common stocks of domestic and foreign companies we believe have
above-average prospects for capital growth, or that may be involved in new or
innovative products, services and processes.

PERMITTED INVESTMENTS                                                  
Under normal market conditions, we invest:                             
                                                                       
 .    in an actively managed, broadly diversified portfolio of growth-oriented
     common stocks;

 .    in at least 20 common stock issues spread across multiple industry groups
     and sectors of the economy;

 .    up to 40% of our assets in initial public offerings or recent start-ups and
     newer issues;

 .    no more than 25% of our assets in foreign companies through American
     Depositary Receipts or similar issues; and

 .    up to 15% of our portfolio in emerging markets.
 
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.

INCOME FUND
 
INVESTMENT OBJECTIVE                                                   
The Income Fund seeks current income and total return.                 
                                                                       
INVESTMENT POLICIES                                                    
We invest in a diversified portfolio of debt and variable-rate debt securities
issued by domestic and foreign issuers. We invest in a broad spectrum of U.S.
issues, including U.S. Government obligations, mortgage- and other asset-backed
securities, and the debt securities of financial institutions, corporations, and
others. We attempt to increase the Fund's performance by applying various fixed-
income management techniques. We combine these techniques with fundamental
economic, credit, and market analysis, while at the same time controlling total
return volatility by targeting the Fund's duration within a narrow band (between
70% and 130%) around the duration of the Lipper Corporate A-Rated Debt Average.

PERMITTED INVESTMENTS                                                  
Under normal market conditions, we invest:                             
 
 .    up to 70% of our total assets in corporate debt securities such as bonds,
     debentures and notes, and other debt securities that can be converted into
     or exchanged for common stocks;

 .    at least 30% of our total assets in U.S. Government obligations;

 .    up to 50% of our total assets in mortgage-backed securities and up to 25%
     of our assets in asset-backed securities; and

 .    at least 80% of our total assets in investment-grade securities. The Fund
     may invest up to 20% of its total assets in below investment-grade
     securities rated, at the time of purchase, in the fifth highest long-term
     rating category assigned by an NRSRO or unrated and determined by us to be
     of comparable quality.
 
We may also invest in zero coupon securities and enter into dollar roll
transactions. We invest primarily in securities with maturities (or average life
in the case of mortgage-backed and similar securities) ranging from overnight to
40 years. It is anticipated that the Fund's portfolio will have an average
dollar-weighted maturity of between 3 and 15 years.

IMPORTANT RISK FACTORS                                       
                                                             
Mortgage- and asset-backed securities may not be guaranteed by the U.S.
Treasury. Mortgage-backed securities are subject to prepayment risk, which can
lower the rate of return on such securities. The Income Fund may invest in lower
rated securities, which tend to be more sensitive to economic conditions and
involve greater credit risk than higher rated securities.

Risks beginning on page ___. They are all important to your investment choice.

INTERMEDIATE GOVERNMENT INCOME FUND
 
INVESTMENT OBJECTIVE                                                   
The Intermediate Government Income Fund seeks current income, consistent with
safety of principal.

INVESTMENT POLICIES                                                    
We invest primarily in fixed and variable rate U.S. Government obligations.
Under normal circumstances, we intend to invest at least 65% of our total assets
in U.S. Government obligations and may invest up to 35% of our total assets in
debt securities that are not U.S. Government obligations. We emphasize the use
of intermediate maturity securities to reduce interest rate risk and use
mortgage-backed securities to enhance yield.

PERMITTED INVESTMENTS
Under normal market conditions, we invest:
 
 .    at least 65% of our total assets in U.S. Government obligations;

 .    up to 50% of our total assets in mortgage-backed securities, and up to 25%
     of our total assets in asset-backed securities; and

 .    up to 10% of our total assets in zero coupon securities.
 
As part of our mortgage-backed securities investments, we may enter into dollar
rolls. We may not invest more than 25% of our total assets in securities issued
or guaranteed by any single agency or instrumentality of the U.S. Government,
except the U.S. Treasury.

We will purchase only securities that are rated, at the time of purchase, within
the two highest rating categories assigned by an NRRO or, if unrated, are
determined by us to be of comparable quality.

We may use options, swap agreements, interest rate caps, floors and collars, and
futures contracts to manage risk. We also may use options to enhance return.
 
IMPORTANT RISK FACTORS
 
Mortgage- and asset-baked 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.

SHORT-INTERMEDIATE U.S. GOVERNMENT INCOME FUND

INVESTMENT OBJECTIVE                                                   
The Short-Intermediate U.S. Government Income Fund seeks current income, while
preserving capital.

INVESTMENT POLICIES                                                    
We seek current income by actively managing a diversified portfolio consisting
primarily of short- to intermediate-term U.S. Government obligations. We may
invest in securities of any maturity. Under ordinary circumstances, we expect to
maintain a dollar-weighted average maturity of between 2 and 5 years. We seek to
preserve capital by shortening average maturity when we expect interest rates to
increase and to increase total return by lengthening maturity when we expect
interest rates to fall.

PERMITTED INVESTMENTS                                                  
Under normal market conditions, we invest:                             
                                                                       
 .    at least 65% of our total assets in U.S. Government obligations or
     repurchase agreements collateralized by U.S. Government obligations;

 .    in investment grade corporate debt securities including asset-backed
     securities;

 .    no more than 5% of our total assets in securities downgraded below
     investment-grade after we acquired them;

 .    up to 25% of assets in dollar-denominated debt of U.S. branches of foreign
     banks or foreign branches of U.S. banks; and

 .    in stripped Treasury securities, adjustable-rate mortgage securities, and
     adjustable portions of collateralized mortgage obligations.
 
IMPORTANT RISK FACTORS
 
Mortgage- and asset-baked 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.
 
Stripped Treasury securities have greater interest rate risk than traditional
government securities with identical credit ratings and like maturities.

TAX-FREE INCOME FUND
 
INVESTMENT OBJECTIVE                                                   
The Tax-Free Income Fund seeks current income exempt from federal income taxes.

INVESTMENT POLICIES                                                    
We invest primarily in a portfolio of investment grade municipal securities. We
invest at least 80% of our total assets in municipal securities paying interest
exempt from federal income taxes, including the federal AMT.
 
PERMITTED INVESTMENTS
Under normal market conditions, we invest:
 
 .    at least 80% of our total assets in municipal obligations that pay interest
     exempt from federal income tax; 

 .    up to 20% of our total assets in securities subject to the federal AMT; and

 .    in municipal obligations rated in the four highest credit categories by
     nationally recognized rating organizations.
 
The average dollar-weighted maturity of the Fund's assets normally will be
between 10 and 20 years, but may vary depending on market conditions. In
general, the longer the maturity of a municipal security, the higher the rate of
interest is pays. However, a longer maturity is generally associated with a
higher level of volatility in the market value of a security. We emphasize
investments in municipal securities with interest income rather than stability
of the Fund's net asset value.

IMPORTANT RISK FACTORS
 
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.

MONEY MARKET FUND
 
INVESTMENT OBJECTIVE
The Money Market Fund seeks high current income, while preserving capital and
liquidity.
 
INVESTMENT POLICIES
We actively manage a portfolio 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 dollar-weighted average maturity of 90 days
or less. We may also make certain other investments 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;

 .    municipal obligations; and

 .    shares of other money market funds.
 
IMPORTANT RISK FACTORS
 
Although we seek to maintain a $1.00 per share net asset value, there is no
guarantee that we will be able to do so. Fluctuations in share value may cause a
loss or gain in principal. Generally, short-term funds do not earn as high a
level of income as funds that invest in longer-term instruments.

INVESTMENT OBJECTIVE
The Municipal Money Market Fund seeks high current income exempt from federal
income taxes, while preserving capital and liquidity.
 
INVESTMENT POLICIES
We invest 100% of our assets in short-term municipal instruments, including
leases. These investments may have fixed, variable, or floating rates of
interest and may be zero coupon securities. We normally will invest at least 80%
of our total assets in federally tax-exempt instruments whose income may be
subject to the federal AMT. We may invest up to 20% of our total assets in
securities that pay interest income subject to federal income tax.
 
PERMITTED INVESTMENTS
Under normal market conditions, we invest:
 
 .    at least 80% of our assets in federally tax-exempt instruments whose income
     may be subject to the federal AMT; and

 .    up to 35% of our assets in issuers located in a single state.
 
We may invest more than 25% of our total assets in industrial development bonds
and in participation interests in these types of bonds guaranteed by banks and 
insurance companies.

U.S. GOVERNMENT MONEY MARKET FUND

INVESTMENT OBJECTIVE

preserving capital and liquidity.

INVESTMENT POLICIES

PERMITTED INVESTMENTS
Under normal market conditions, we invest at least 65% of our assets:

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 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 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. This practice
     is expected to have limited, if any, effect on Fund objectives over the
     long term.

 .    The Asset Allocation Fund and the taxable income funds invest a portion of
     their assets in GNMAs, FNMAs and 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 entity, is offered to investors through securities
     dealers. Mortgage-backed securities are subject to prepayment risk, which
     can alter the maturity of the securities and also reduce the rate of return
     on such investments. Collateralized mortgage obligations ("CMOs") represent
     principal-only and interest-only portions of such securities that 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 Income Fund 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 rate "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.

GENERAL INVESTMENT RISKS (CONT'D)

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..

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 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. 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

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.

     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 Asset Allocation, Income Equity, Small Cap,
Intermediate Government Income and Tax-Free Income 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.

             PROSPECTUS HAVE THE FOLLOWING SALES CHARGE SCHEDULE:

     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:

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

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.

SHAREHOLDERS OF FORMER STAGECOACH FUNDS who exchanged into these Funds on
September 17, 1999, are subject to the above CDSC schedule based on the purchase
date(s) of the Stagecoach shares, except that such shares convert to Class A
shares automatically after six years.

Class B shares purchased by shareholders of former Stagecoach Funds prior to 
March 3, 1997 are subject to a CDSC if they are redeemed within four years of 
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 these Class B shares for Class B shares of another Fund, you will
retain these CDSC schedules on your exchanged shares, but additional shares of
the newly purchased Fund 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:

 .    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.

                                       31
<PAGE>
 
REDUCED SALES CHARGES (CONT'D)

 .    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 a 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.)

 .    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; o 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.

REDUCED SALES CHARGES (CONT'D)        

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 a Distribution Plan for the Class B and Class C shares each
class of the Funds. 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 fees paid under these
plans are as follows:

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.

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, between Class C shares or between either
     Class B or Class C shares and a Wells Fargo money market fund 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 from any share class to a money market fund can only be
     reexchanged 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, Class B or Class C shares and non-institutional class shares
     to a non-institutional money market fund.

 .    Exchanges into Money Market Fund Class B shares are subject to certain
     restrictions in addition to those described above.

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). The Money Market Fund calculates NAV at 12:00 noon
     (Pacific time)/2:00 p.m. (Central time), and the other money market funds
     calculate NAV at 2:00 p.m. (Pacific time)/4:00 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 non-money market 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.

 .    The money market Funds are open for business each day Wells Fargo Bank is 
     open for business and are closed generally on federal bank holidays.

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 non-money market 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). We determine the NAV of the Money Market Fund at 12:00 noon 
(Pacific time)/2:00 P.M. (Central time) and we determine the NAV of the other
money market funds each day as of 2:00 P.M. (Pacific time)/4:00 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 equity funds, except the Small Cap Fund, pay any
dividends quarterly. The Small Cap Fund pays any dividends annually. The income
and money market 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 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.

                                       39
<PAGE>
 
ADDITIONAL SERVICES AND OTHER INFORMATION (CONT'D)

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 any 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 is 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.

Except in the case of Money Market Funds, 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. As long as a Money Market Fund 
continually maintains a $1.00 NAV, you ordinarily will not recognize taxable 
gain or loss on the redemption or exchange of such Fund shares.

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 13% rate on distributions from and redemption 
proceeds paid by a Fund.

                              TABLE OF PREDECESSORS

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 __. 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. Although the money market funds seek
to preserve the value of your investment at $1.00 per share, it is possible to 
lose money by investing in these funds.
- ------------------------------------------------------------------------------
COMMON RISKS FOR THE FUNDS
- ------------------------------------------------------------------------------
 
EQUITY SECURITIES. The equity and allocation 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 investments 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 Asset Allocation Fund, the income funds, and money market
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 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. The equity funds may invest some of
their assets in debt securities.

FUND                      SPECIFIC RISKS
- -------------------------------------------------------------------------------

EQUITY AND ALLOCATION
 FUNDS
- -------------------------------------------------------------------------------
ASSET ALLOCATION FUND This Fund uses an investment model that 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 FUND           This Fund is primarily subject to the equity securities
                      risks described in the Common Risks section, above.
- -------------------------------------------------------------------------------
INCOME EQUITY FUND    Stocks selected for their high dividend income may be more
                      sensitive to interest rate changes than other stocks. This
                      Fund is primarily subject to the equity Risks section,
                      above.

- -------------------------------------------------------------------------------
SMALL CAP FUND        This Fund may invest in companies that pay low or no
                      dividends, have smaller market capitalizations, have less
                      market liquidity, have no or relatively short operating
                      histories, or are newly public companies. Some of these
                      companies have aggressive capital structures, including
                      high debt levels, or are involved in rapidly growing or
                      changing industries and/or new technologies. Because the
                      Fund may invest in such aggressive securities, share
                      prices may rise and fall more than the share prices other
                      funds. In addition, our active trading investment strategy
                      may result in a higher-than-average portfolio turnover
                      ratio, increased trading expenses, and high short-term
                      capital gains.

ASSET ALLOCATION FUND
 
INVESTMENT OBJECTIVE
The Asset Allocation Fund seeks long-term total return, consistent with
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                                                 
The asset classes we invest in are:                                   
                                                                      
 .    Stock Investments -- We invest in common stocks representative of the S&P
     500 Index. We do not individually select common stocks on the basis of
     traditional investment analysis. Instead, stock investments are made
     according to a weighted formula intended to match the total return 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 in this Index have remaining
     maturities of twenty 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 may invest:
 
 .    In call and put options on stock indexes, stock index futures, options on
     stock index futures, and interest rate futures contracts as a substitute
     for a comparable market position in stocks or bonds;

 .    In interest rate and index swaps; and

 .    Up to 25% of total assets in foreign obligations qualifying as money market
     investments.
 
We manage the allocation of investments in the Fund's portfolio assuming a
"normal" allocation of 60% stocks and 40% bonds. This is not a "target"
allocation but rather is a design feature that is intended to set a level of
risk tolerance for the Fund.

We are not required to keep a minimum investment in any of the three asset
classes described above, nor are we prohibited from investing substantially all
of our assets in a single class. The allocation may shift at any time.

IMPORTANT RISK FACTORS                                    
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.

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

GROWTH FUND
  
  
INVESTMENT OBJECTIVE                                                  
The Growth Fund seeks long-term capital appreciation.                 
                                                                      
INVESTMENT POLICIES                                                   
We seek long-term capital appreciation by investing primarily in common stocks
and other equity securities and we look for companies that have a strong
earnings growth trend that we believe have above-average prospects for future
growth. 

PERMITTED INVESTMENTS
Under normal market conditions, we invest:
 
 .    at least 65% of our total assets in equity securities, including common and
     preferred stocks, and securities convertible into common stocks;

 .    the majority of our total assets in issues of companies with market
     capitalization that falls within the range of the Russell 1000 Index (As of
     [MARCH 31, 1999,] this range was from [$____ MILLION TO $____ BILLION.] The
     range is expected to change frequently.);

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

 .    up to 15% of our total assets in emerging markets.
 
IMPORTANT RISK FACTORS
This Fund is primarily subject to the equity market risks described in the
Common Risks section.

INCOME EQUITY FUND
 
INVESTMENT OBJECTIVE                                                   
The Income Equity Fund seeks long-term capital appreciation and above-average
dividend income.

INVESTMENT POLICIES                                                    
We invest primarily in the common stock of large, high-quality domestic
companies that have above-average return potential based on current market
valuations. We primarily emphasize investments in securities of companies with
above-average dividend income. We use various valuation measures when selecting
securities for the portfolio, including above-average dividend yields and below
industry average price-to-earnings, price-to-book and price-to-sales ratios. We
consider large companies to be those whose market capitalization is greater than
the median of the Russell 1000 Index.

PERMITTED INVESTMENTS                                                  
Under normal market conditions, we invest:                             
                                                                       
 .    at least 65% of our total assets in equity securities; and

 .    in issues of companies with market capitalization greater than the median
     of the Russell 1000 Index (as of March 31, 1999, this median was [$____
     BILLION;] the range is expected to change frequently). 

We may invest in preferred stock, convertible securities, and securities of
foreign companies. We will normally limit our investment in a single issuer to
10% or less of our total assets.

IMPORTANT RISK FACTORS
Stocks selected for their high dividend yields may be more sensitive to interest
rate changes than other stocks. 

You should consider the Common Risks on page ___, the General Investment Risks
beginning on page ___ and the specific risks listed here. They are all important
to your investment choice.
 
CORE/GATEWAY ARRANGEMENT                                     
The Income Equity Fund is a "gateway" fund in a "core/gateway" arrangement. In
this arrangement, 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 Income Equity Fund also
refer to the core portfolio.

PORTFOLIO MANAGERS                                          
 .    DAVID L. ROBERTS, CFA

     from Norwest Investment Management, Inc. ("NIM"), where he had managed
     portfolios for NIM or its affiliates since 1972. He has over twenty-six
     years of investment management experience.

 .    GARY J. DUNN, CFA
     Will co-manage the Income Equity Fund upon inception. Mr. Dunn joins WCM

SMALL CAP FUND
 
INVESTMENT OBJECTIVE                                                   
The Small Cap Fund seeks long-term capital appreciation.               
                                                                       
INVESTMENT POLICIES                                                    
We actively manage a diversified portfolio of common stocks issued by companies
whose market capitalization falls within the range of the Russell 2000 Index. As
of March 31, 1999, the range was [$___ MILLION TO $____ BILLION,] but it is
expected to change frequently. We will sell the stock of any company whose
market capitalization exceeds the range of this index for sixty consecutive
days.                                                                       

We invest in the common stocks of domestic and foreign companies we believe have
above-average prospects for capital growth, or that may be involved in new or
innovative products, services and processes.

PERMITTED INVESTMENTS                                                  
Under normal market conditions, we invest:                             
                                                                       
 .    in an actively managed, broadly diversified portfolio of growth-oriented
     common stocks;

 .    in at least 20 common stock issues spread across multiple industry groups
     and sectors of the economy;

 .    up to 40% of our assets in initial public offerings or recent start-ups and
     newer issues;

 .    no more than 25% of our assets in foreign companies through American
     Depositary Receipts or similar issues; and

 .    up to 15% of our portfolio in emerging markets.
 
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.

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

INCOME FUND
 
INVESTMENT OBJECTIVE                                                   
The Income Fund seeks current income and total return.                 
                                                                       
INVESTMENT POLICIES                                                    
We invest in a diversified portfolio of debt and variable rate debt securities
issued by domestic and foreign issuers. We invest in a broad spectrum of U.S.
issues, including U.S. Government obligations, mortgage- and other asset-backed
securities, and the debt securities of financial institutions, corporations, and
others. We attempt to increase the Fund's performance by applying various fixed
income management techniques. We combine these techniques with fundamental
economic, credit, and market analysis while at the same time controlling total
return volatility by targeting the Fund's duration within a narrow band (between
70% and 130%) around the duration of the Lipper Corporate A-Rated Debt Average.

PERMITTED INVESTMENTS                                                  
Under normal market conditions, we invest:                             
 
 .    up to 70% of our total assets in corporate debt securities such as bonds,
     debentures and notes, and debt securities that can be converted into or
     exchanged for common stocks;

 .    at least 30% of our total assets in U.S. Government obligations;

 .    up to 50% of our total assets in mortgage-backed securities and up to 25%
     of our assets in asset-backed securities; and

 .    at least 80% of our total assets in investment-grade securities. The Fund
     may invest up to 20% of its total assets in below investment-grade
     securities rated, at the time of purchase, in the fifth highest long-term
     rating category assigned by an NRSRO or unrated and determined by us to be
     of comparable quality.
 
We may also invest in zero coupon securities and enter into dollar roll
transactions. We invest primarily in securities with maturities (or average life
in the case of mortgage-backed and similar securities) ranging from overnight to
40 years. It is anticipated that the Fund's portfolio will have an average
dollar-weighted maturity of between 3 and 15 years.
 
IMPORTANT RISK FACTORS                                        
                                                              
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 Income Fund may invest in
lower-rated securities, which tend to be more sensitive to economic conditions
and involve greater credit risk than higher-rated securities.

You should consider the Common Risks on page ___, and the General Investment
Risks beginning on page ___. They are all important to your investment choice.

     where she was Director of Taxable Fixed-Income investments. She had
     managed portfolios for NIM or its affiliates since 1992. She has over
     eighteen years of investment management experience.

INTERMEDIATE GOVERNMENT INCOME FUND
 
INVESTMENT OBJECTIVE                                                   
The Intermediate Government Income Fund seeks current income, consistent with
safety of principal.

INVESTMENT POLICIES                                                    
We invest primarily in fixed and variable rate U.S. Government obligations.
Under normal circumstances, we intend to invest at least 65% of our total assets
in U.S. Government obligations and may invest up to 35% of our total assets in
debt securities that are not U.S. Government obligations. We emphasize the use
of intermediate maturity securities to reduce interest rate risk and use
mortgage-backed securities to enhance yield.

PERMITTED INVESTMENTS
Under normal market conditions, we invest:
 
 .    at least 65% of our total assets in U.S. Government obligations;

 .    up to 50% of our total assets in mortgage-backed securities, and up to 25%
     of our total assets in asset-backed securities; and

 .    up to 10% of our total assets in zero coupon securities.
 
As part of our mortgage-backed securities investments, we may enter into dollar
rolls. We may not invest more than 25% of our total assets in securities issued
or guaranteed by any single agency or instrumentality of the U.S. Government,
except the U.S. Treasury.

We will purchase only securities that are rated, at the time of purchase, within
the two highest rating categories assigned by an NRRO or, if unrated, are
determined by us to be of comparable quality.
 
We may use options, swap agreements, interest rate caps, floors and collars, and
futures contracts to manage risk. We also may use options to enhance return.
 
IMPORTANT RISK FACTORS
 
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.

SHORT-INTERMEDIATE U.S. GOVERNMENT INCOME FUND
 
INVESTMENT OBJECTIVE                                                   
The Short-Intermediate U.S. Government Income Fund seeks current income, while
preserving capital.

INVESTMENT POLICIES                                                    
We seek current income by actively managing a diversified portfolio consisting
primarily of short- to intermediate-term U.S. Government obligations. We may
invest in securities of any maturity. Under ordinary circumstances, we expect to
maintain a dollar-weighted average maturity of between 2 and 5 years. We seek to
preserve capital by shortening average maturity when we expect interest rates to
increase and to increase total return by lengthening maturity when we expect
interest rates to fall.

PERMITTED INVESTMENTS                                                  
Under normal market conditions, we invest:
 
 .    at least 65% of our total assets in U.S. Government obligations or
     repurchase agreements collateralized by U.S. Government obligations;

 .    in investment grade corporate debt securities including asset-backed
     securities;

 .    no more than 5% of our total assets in securities downgraded below
     investment-grade after we acquired them;

 .    up to 25% of assets in dollar-denominated debt of U.S. branches of foreign
     banks or foreign branches of U.S. banks; and

 .    in stripped Treasury securities, adjustable-rate mortgage securities, and
     adjustable portions of collateralized mortgage obligations.
 
IMPORTANT RISK FACTORS
 
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.
 
Stripped Treasury securities have greater interest rate risk than traditional
government securities with identical credit ratings and like maturities.

TAX-FREE INCOME FUND
 
INVESTMENT OBJECTIVE                                                   
The Tax-Free Income Fund seeks current income exempt from federal income taxes.

INVESTMENT POLICIES                                                    
We invest primarily in a portfolio of investment grade municipal securities. We
invest at least 80% of our total assets in municipal securities paying interest
exempt from federal income taxes, including the federal AMT.
 
PERMITTED INVESTMENTS
Under normal market conditions, we invest:
 
 .    at least 80% of our total assets in municipal obligations that pay interest
     exempt from federal income tax;

 .    up to 20% of our total assets in securities subject to the federal AMT; and

 .    in municipal obligations rated in the four highest credit categories by
     nationally recognized rating organizations.
 
The average dollar-weighted maturity of the Fund's assets normally will be
between 10 and 20 years, but may vary depending on market conditions. In
general, the longer the maturity of a municipal security, the higher the rate of
interest is pays. However, a longer maturity is generally associated with a
higher level of volatility in the market value of a security. We emphasize
investments in municipal securities with interest income rather than stability
of the Fund's net asset value.
 
IMPORTANT RISK FACTORS
 
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.

CASH INVESTMENT FUND
 
INVESTMENT OBJECTIVE
The Cash Investment Fund seeks high current income, preservation of capital and
liquidity.

INVESTMENT POLICIES
We invest in a broad spectrum of high quality money market instruments. These
include commercial paper, 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. We limit our investments in
obligations of financial institutions to institutions 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:
 
 .    at least 80% of our assets in high-quality, short-term instruments of
     domestic and foreign issuers;

 .    up to 25% of our assets in foreign obligations; and

 .    not more than 25% of our assets in any single industry, subject to certain 
     exceptions (see Statement of Additional Information for details).
 
IMPORTANT RISK FACTORS
 
Although we seek to maintain a $1.00 per share net asset value, there is no
guarantee that we will be able to do so. Fluctuations in share value may cause a
loss or gain in principal. Generally, short-term funds do not earn as high a
level of income as funds that invest in longer-term instruments.

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 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 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. This practice is expected to
   have limited, if any, effect on Fund objectives over the long term.
                                                                       
 .  The Asset Allocation Fund and the taxable income funds invest a portion of
   their assets in GNMAs, FNMAs and 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 entity, is offered to investors through securities dealers.
   Mortgage-backed securities are subject to prepayment risk, which can alter
   the maturity of the securities and also reduce the rate of return on such
   investments. Collateralized mortgage obligations ("CMOs") represent  
   principal-only and interest-only portions of such securities that 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 Income Fund 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 rate "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.

<PAGE>
 
GENERAL INVESTMENT RISKS (CONT'D)
 
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.

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 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. 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.

THESE INVESTMENT PRACTICES AND RISKS ARE COMMON TO ALL THE FUNDS:

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.

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). The money market funds calculate NAV at 2:00 p.m. (Pacific
   time)/4:00 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.

   .  $25,000 per Fund for all investments after your first. 

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;

YOUR ACCOUNT (CONT'D)            
 
 .  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 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.

OTHER INFORMATION
 
DIVIDEND AND CAPITAL GAIN DISTRIBUTIONS
The Funds in this Prospectus pay dividends periodically and make capital gains
distributions annually. The equity funds, except the Small Cap Fund, pay any
dividends quarterly. The Small Cap Fund pays any dividends annually. The income
and money market 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 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.

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.

Except in the case of Money Market Funds, 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 have paid) for them. As long as a money market fund 
continually maintains a $1.00 NAV, you ordinarily will not recognize taxable 
gain or loss on the redemption or exchange of such Fund shares.

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.

     On March 25, 1999, the Board of Trustees of Norwest Advantage Funds
("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

operations on January 2, 1992, as successor to the Asset Allocation Fund of the
Wells Fargo Investment Trust for Retirement Programs ("WFIT"), which commenced
operations on November 13, 1986.  The predecessor Stagecoach Balanced Fund was
originally organized on July 1, 1990 as the Pacifica Balanced Fund, an

                            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 (i) securities issued or guaranteed by
the United States Government, its agencies or instrumentalities, [(II) MUNICIPAL
SECURITIES, (III) IN THE CASE OF THE INCOME EQUITY FUND, MORTGAGE-RELATED OR
HOUSING RELATED SECURITIES AND FOREIGN GOVERNMENT SECURITIES, (IV) IN THE CASE
OF THE ASSET ALLOCATION FUND, ANY INDUSTRY IN WHICH THE S&P 500 INDEX BECOMES
CONCENTRATED TO THE SAME DEGREE DURING THE SAME PERIOD, AND (V) IN THE CASE OF
THE ASSET ALLOCATION FUND, MONEY MARKET INSTRUMENTS INVESTED IN THE BANKING
INDUSTRY (BUT THE FUND WILL NOT DO SO UNLESS THE U.S. SECURITIES AND EXCHANGE
COMMISSION ("SEC") STAFF CONFIRMS THAT IT DOES NOT OBJECT TO THE FUND RESERVING
FREEDOM OF ACTION TO CONCENTRATE INVESTMENTS IN THE BANKING INDUSTRY);]

     (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.

                                       2
<PAGE>
 
     (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,
[(III) IN THE CASE OF THE ASSET ALLOCATION FUND, PARTICIPATING IN FORWARD
CONTRACTS AND INTEREST RATE AND INDEX SWAPS, AND (IV) IN THE CASE OF THE GROWTH
FUND PURCHASING SECURITIES OF AN ISSUER WHICH INVESTS OR DEALS IN COMMODITIES OR
COMMODITY CONTRACTS.]

     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.

                                       3
<PAGE>
 
     (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 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 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, 

                                       5
<PAGE>
 
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 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 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 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.

     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 

                                       6
<PAGE>
 
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.

     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 

                                       7
<PAGE>
 
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.
Foreign currency futures contracts and foreign currency transactions 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 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 

                                       8
<PAGE>
 
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.

     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 

                                       9
<PAGE>
 
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 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.

                                       10
<PAGE>
 
     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.

     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 

                                       11
<PAGE>
 
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 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 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.

                                       12
<PAGE>
 
     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.

     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.

                                       13
<PAGE>
 
     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 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 

                                       14
<PAGE>
 
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.

     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 

                                       15
<PAGE>
 
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.

     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

                                       16
<PAGE>
 
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.

     Warrants
     --------

     The 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.

                                       17
<PAGE>
 
     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

     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

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.

     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 

                                       24
<PAGE>
 
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.

     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:  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.

     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.

                                       27

     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 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

                                       28
<PAGE>
 
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 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 April 1, 1999, Wells Fargo
Bank and its affiliates provided investment Advisory services for approximately
[$__BILLION] of assets of individual, trusts, estates and institutions and [$__
BILLION] of mutual fund assets.

                                       29

     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 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

                                       31
<PAGE>
 
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 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

                                       32
<PAGE>
 
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 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

                                       34
<PAGE>
 
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 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

                                       35
<PAGE>
 
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 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

                                       36
<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 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

                                       37
<PAGE>
 
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 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

                                       38
<PAGE>
 
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.

     For tax years beginning after December 31, 1997, an individual with $300 or
less of creditable foreign taxes generally is exempt from foreign source income
and certain other limitations imposed by the Code on claiming a credit for such
taxes.  The $300 amount is increased to $600 for joint filers.

     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.

     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-

                                       39
<PAGE>
 
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."

                            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 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, [PROVIDED THAT THERE IS NO
LIMITATION WITH RESPECT TO INVESTMENT IN (I) SECURITIES ISSUED OR GUARANTEED BY
THE UNITED STATES GOVERNMENT, ITS AGENCIES OR INSTRUMENTALITIES, (II) MUNICIPAL
SECURITIES, (III) FOREIGN GOVERNMENT SECURITIES, AND (IV) OBLIGATIONS OF
DOMESTIC OR FOREIGN BANKS. FOR PURPOSES OF THIS POLICY (I) "MORTGAGE RELATED
SECURITIES," AS THEY ARE DEFINED IN THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED (THE "1934 ACT") ARE TREATED AS SECURITIES OF AN ISSUER IN THE INDUSTRY
OF THE PRIMARY TYPE OF ASSET BACKING THE SECURITY; (II) FINANCIAL SERVICES
COMPANIES ARE CLASSIFIED ACCORDING TO THE END USERS OF THEIR SERVICES (FOR
EXAMPLE, AUTOMOBILE FINANCE, BANK FINANCE, AND DIVERSIFIED FINANCE), (III)
UTILITY COMPANIES ARE CLASSIFIED ACCORDING TO THEIR SERVICES (FOR EXAMPLE, GAS,
GAS TRANSMISSION, ELECTRIC AND GAS, ELECTRIC AND TELEPHONE), (IV) IN THE CASE OF
THE MUNICIPAL MONEY MARKET FUND AND THE [SERVICE] MUNICIPAL MONEY MARKET FUND, A
SECURITY IS CONSIDERED TO BE ISSUED BY THE GOVERNMENTAL ENTITY (OR ENTITIES)
WHOSE ASSETS AND REVENUES BACK THE SECURITY, OR, WITH RESPECT TO A PRIVATE
ACTIVITY BOND THAT IS BACKED ONLY BY THE ASSETS AND REVENUES OF A
NONGOVERNMENTAL USER, SUCH NONGOVERNMENTAL USER. IN CERTAIN CIRCUMSTANCES, THE
GUARANTOR OF A GUARANTEED SECURITY MAY ALSO BE CONSIDERED TO BE AN ISSUER IN
CONNECTION WITH SUCH GUARANTEE, EXCEPT THAT A GUARANTEE OF A SECURITY SHALL NOT
BE DEEMED TO BE A SECURITY ISSUED BY THE GUARANTOR WHEN THE VALUE OF ALL
SECURITIES ISSUED AND GUARANTEED BY THE GUARANTOR, AND OWNED BY A FUND, DOES NOT
EXCEED 10% OF THE VALUE OF THE FUND'S TOTAL ASSETS;]

     (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;

                                       3
<PAGE>
 
     (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 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 10% 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 (all non-money market funds) 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

                                       4
<PAGE>
 
assets would be invested in initial margin and premiums (excluding amounts "in-
the-money") required to establish the contracts.

          The 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 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 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 will vary based upon the prepayment experience of 
the underlying asset pool and prevailing interest rates at the time of 
prepayment.

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

     The Funds, except the [Service] Treasury Plus Money Market Fund, 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 and foreign
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.

                                       5
<PAGE>
 
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 [Service] Treasury Plus Money Market Fund, 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.

     Derivative Securities
     ---------------------

     The internal investment policies of the Advisor prohibit the Funds'
purchase of many types of floating-rate derivative securities that are
considered potentially volatile. The following types of derivative securities
ARE NOT permitted investments for the Funds:

          .  capped floaters (on which interest is not paid when market rates
             move above a certain level);

          .  leveraged floaters (whose interest rate reset provisions are based
             on a formula that magnifies changes in interest rates);

          .  range floaters (which do not pay any interest if market interest
             rates move outside of a specified range);

          .  dual index floaters (whose interest rate reset provisions are tied
             to more than one index so that a change in the relationship

                                       6
<PAGE>
 
               between these indices may result in the value of the instrument
               falling below face value); and

          .    inverse floaters (which reset in the opposite direction of their
               index).

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

     The Funds 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 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 [Service] Treasury Plus Money Market Fund, 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

                                       7
<PAGE>
 
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
    ----------------------------------------------------------------------------

    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.  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.

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

                                       9
<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.

     Ratings of Securities
     ---------------------

     Any security that a Fund purchases must present minimal credit risks and be
of "high quality," or in the case of the [Service] Treasury Plus Money Market
Fund, be of the "highest quality."  "High quality" means to be rated in the top
two rating categories and "highest quality" means to be rated only in the top
rating category, by the requisite Nationally Recognized Ratings Organization
("NRRO") or, if unrated, determined to be of comparable quality to such rated
securities by the Advisor, under guidelines adopted by the Board of Trustees.

     The ratings of Moody's, S&P, 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.

     Repurchase Agreements
     ---------------------

     Each 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 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

                                       10
<PAGE>
 
affiliated with the investment advisor. The Funds may participate in pooled
repurchase agreement transactions with other funds advised by Wells Fargo Bank.

     Unrated and Downgraded Investments
     ----------------------------------

     The Funds 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 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 Funds may invest in obligations of agencies and instrumentalities of
the U.S. Government ("U.S. Government obligations").  The [Service] 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.

Management ("WCM") to serve as Investment Sub-Advisor to the Money Market 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 and also furnishes such additional reports

     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 $960 MILLION OF THE
FUND'S AVERAGE DAILY NET ASSETS AND 0.04% OF NET ASSETS OVER $960 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

     Wells Fargo Bank has engaged Norwest Investment Management ("NIM") to serve
as Investment Sub-Advisor to each Fund other than the Money Market 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, 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.

                                       15
<PAGE>
 
     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 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 the Class
A, Class B 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.

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.

     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:
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.

     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 

                                       18
<PAGE>
 
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

     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

                                       19

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 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 

                                       20
<PAGE>
 
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 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 

                                       21
<PAGE>
 
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 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 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 2:00 p.m. (Pacific
time)/4:00 p.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 

                                       22
<PAGE>
 
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 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

                                       23
<PAGE>
 
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.

     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.

                                       24

                            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 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 

                                       25
<PAGE>
 
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 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 

                                       26
<PAGE>
 
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 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.

                                       27
<PAGE>
 
     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 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 

                                       28
<PAGE>
 
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 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.

                                       29
<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 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.

     Additional Considerations for the Municipal Money Market and [Service] 
     ----------------------------------------------------------------------
Municipal Money Market Funds. 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 Municipal Money Market and [Service] Municipal Money Market Funds intend to 
so qualify and are designed to provide investors with a high level of income 
exempt from federal income tax.

     The portion of total dividends paid by the Municipal Money Market and 
[Service] Municipal Money Market Funds 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
their 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 Municipal 
Money Market and [Service] Municipal Money Market Funds will notify their 
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 a 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 Municipal Money Market and [Service] Municipal Money Market 
Funds 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 Municipal Money Market Fund or [Service] 
Municipal Money Market 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 Municipal Money Market and [Service] Municipal Money Market Funds. 
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 Municipal Money Market Fund or 
[Service] Municipal Money Market Fund. Furthermore, shareholders will not be 
permitted to deduct any of their share of expenses of the Municipal Money Market
Fund or [Service] Municipal Money Market Fund in computing their AMT. With 
respect to a corporate shareholder of the Municipal Money Market Fund or 
[Service] Municipal Money Market 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 Municipal Money Market Fund or [Service] Municipal Money 
Market 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 benefit from the exempt status of dividends from the Fund.
Such dividends may ultimately be taxable to the beneficiaries when distributed 
to them.

     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 six 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 

                                       30
<PAGE>
 
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.

     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.

                                   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.

                          HISTORICAL FUND INFORMATION

    On March 25, 1999, the Board of Trustees of Norwest Advantage Funds
("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 INCOME FUND will commence operations on September 17, 1999, as successor
to the Income, Total Return Bond, and Performa Strategic Value Bond Funds of
Norwest. The Norwest Income Fund commenced operations on August 5, 1993, the
Norwest Total Return Bond Fund commenced operations on December 31, 1993, and
the Performa Strategic Value Bond Fund commenced operations on October 15, 1997.
For accounting purposes, the Norwest Income predecessor portfolio is considered
the surviving entity, and the financial highlights shown for periods prior to
September 17, 1999 are the financial highlights of the Norwest Income Fund.

    The INTERMEDIATE GOVERNMENT INCOME FUND will commence operations on
September 17, 1999, as successor to the U.S. Government Income and U.S.
Government Allocation Funds of Stagecoach and the Intermediate Government Income

commenced operations as a portfolio of Overland Express Fund, Inc. ("Overland")
on January 1, 1992, as the successor to the Ginnie Mae Fund of the Wells Fargo
Investment Trust for Retirement Programs ("WFIT"), which commenced operations on
January 3, 1991. On December 12, 1997, as part of the consolidation of Overland
into Stagecoach, the U.S. Government Income Fund of Overland was reorganized
with and into the Stagecoach U.S. Government Income Fund. The predecessor
Stagecoach U.S. Government Allocation Fund commenced operations on January 2,
1992 as successor to the Fixed-Income Strategy Fund of WFIT, which commenced
operations on March 31, 1987. The predecessor Norwest Intermediate Government
Income Fund commenced operations on November 11, 1994. For accounting purposes,
the Norwest Intermediate Government Income predecessor portfolio is considered
the surviving entity, and the financial highlights shown for periods prior to
September 17, 1999 are the financial highlights of the Norwest Intermediate
Government Income Fund. The predecessor Norwest Intermediate Government Income
Fund did not offer Class C shares.

    The SHORT-INTERMEDIATE U.S. GOVERNMENT INCOME FUND will commence operations
on September 17, 1999, as successor to Short-Intermediate U.S. Government Income
Fund of Stagecoach and the Limited Term Government Income Fund of Norwest. The
predecessor Stagecoach Short-Intermediate U.S. Government Income Fund commenced
operations on October 27, 1993. The predecessor Norwest Limited Term Government
Income Fund commenced operations on October 1, 1997. For accounting purposes,
the Stagecoach Short-Intermediate U.S. Government Income predecessor portfolio
is considered the surviving entity, and the financial highlights shown for
periods prior to September 17, 1999 are the financial highlights of the
Stagecoach Short-Intermediate U.S. Government Income Fund.

    The TAX-FREE INCOME FUND will commence operations on September 17, 1999, as
successor to the National Tax-Free Fund of Stagecoach and the Tax-Free Income
Fund of Norwest. The predecessor Stagecoach National Tax-Free Fund was
originally organized as an investment portfolio of Westcore Trust under the name
Quality Tax-Exempt Income Fund. On October 1, 1995, the Quality Tax-Exempt
Income Fund was reorganized as the National Tax-Exempt Fund of Pacifica Funds
Trust ("Pacifica"). On the September 6, 1996, the Pacifica National Tax-Exempt
Fund was reorganized as the Stagecoach National Tax-Free Fund. The predecessor
Norwest Tax-Free Income Fund commenced operations on August 2, 1993. For
accounting purposes, the Norwest Tax-Free Income predecessor portfolio is
considered the surviving entity, and the financial highlights shown for periods
prior to September 17, 1999 are the financial highlights of the Norwest Tax-Free
Income Fund. The predecessor Norwest Tax-Free Income Fund did not offer Class C
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 vote of the holders of a majority (as defined in the Investment Trust 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, AND FURTHER
PROVIDED THAT THE TAX-FREE INCOME FUND MAY NOT PURCHASE ANY SECURITIES THAT
WOULD CAUSE 25% OR MORE OF THE VALUE OF ITS TOTAL ASSETS AT THE TIME OF PURCHASE
TO BE INVESTED IN MUNICIPAL OBLIGATIONS WITH SIMILAR CHARACTERISTICS (SUCH AS
PRIVATE ACTIVITY BONDS WHERE THE PAYMENT OF PRINCIPAL AND INTEREST IS THE
ULTIMATE RESPONSIBILITY OF ISSUERS IN THE SAME INDUSTRY, POLLUTION CONTROL
REVENUE BONDS, HOUSING FINANCE AGENCY BONDS OR HOSPITAL BONDS);]
 
    (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;
 

                                       2
<PAGE>
 
    (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 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.

                                       3
<PAGE>
 
        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 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

                                       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. 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.

                                       5
<PAGE>
 
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 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

                                       6
<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 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

                                       7
<PAGE>
 
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
    ----------------------------------

    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 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

                                       8
<PAGE>
 
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.

    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[, BGFA], Stephens or any of their affiliates.

                                       9
<PAGE>
 
    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,

                                       10
<PAGE>
 
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 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.

                                       11
<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 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
    --------------------------

    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

                                       12
<PAGE>
 
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 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
     ---------------

                                       13
<PAGE>
 
     The Tax-Free Income Fund 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 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 Tax-Free Income Fund 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.

                                       14
<PAGE>
 
     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.

     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

                                       15
<PAGE>
 
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.

     Trustee


     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 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 $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.]

     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

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.

                                       20
<PAGE>
 
     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 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

                                       21
<PAGE>
 
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 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.

                                       22
<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.

     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

                                       23
<PAGE>
 
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 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

                                       24
<PAGE>
 
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 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

                                       25
<PAGE>
 
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 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

                                       26
<PAGE>
 
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

                                       27
<PAGE>
 
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 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

                                       28
<PAGE>
 
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

                                       29
<PAGE>
 
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.

     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.

                                       30
<PAGE>
 
     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

                                       31
<PAGE>
 
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,

                                       32
<PAGE>
 
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

                                       33
<PAGE>
 
"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 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

                                       34

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.

Item 30.  Undertakings.
          -------------

          (a)  Not applicable.

          (b)  Not applicable.

          (c)  Registrant undertakes to furnish each person to whom a prospectus
               is delivered with a copy of its most current annual report to
               shareholders, upon request and without charge.

          (d)  Insofar as indemnification for liability arising under the
               Securities Act of 1933 may be permitted to trustees, officers and
               controlling persons of the Registrant pursuant to the provisions
               set forth above in response to Item 27, or otherwise, the
               registrant has been advised that in the opinion of the Securities
               and Exchange Commission such indemnification is against public
               policy as expressed in such Act and is, therefore, unenforceable.
               In the event that a claim for indemnification against such
               liabilities (other than the payment by the registrant of expenses
               incurred or paid by a trustee, officer or controlling person of
               the registrant in the successful defense of any action, suit or
               proceeding) is asserted by such trustee, officer or controlling
               person in connection with the securities being registered, the
               registrant will, unless in the opinion of its counsel the matter
               has been settled by controlling precedent, submit to a court of
               appropriate jurisdiction the question whether such
               indemnification by it is against public policy as expressed in
               the Act and will be governed by the final adjudication of such
               issue.

          (e)  Registrant undertakes to hold a special meeting of its
               shareholders for the purpose of voting on the question of removal
               of a trustee or trustees if requested in writing by the holders
               of at least 10% of the Trust's outstanding voting securities, and
               to assist in communicating with other shareholders as required by
               Section 16(c) of the Investment Company Act of 1940.

       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-
____ and 811-_____) (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 9
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 Statement of Additional Information, which is included as part
of the Registration Statement.


                             Very truly yours,



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