     return;     
*    you are unwilling to accept that you may lose money on your investment;

RIGHT POINT         The National Tax-Free Money Market Mutual Fund seeks to
ARROW]              provide investors with a high level of income exempt from
                    federal income tax, while preserving capital and 
                    liquidity.     
    
                    Investment Policies     
                        
                    We actively manage a portfolio of U.S. dollar-denominated,
                    high-quality, short-term instruments, primarily municipal
                    obligations with remaining maturities of 397 days or less.
                    Among the municipal obligations we buy are bonds, notes and
                    commercial paper issued by or on behalf of the states,
                    territories and possessions of the United States and their
                    political subdivisions and other public authorities. Under
                    normal market conditions we invest substantially all of our
                    assets in debt obligations that are exempt from federal
                    income tax. We maintain an overall dollar-weighted average
                    maturity of 90 days or less.

[LOGO OF A          Permitted Investments
PERCENTAGE          Under normal market conditions, we invest:     
SIGN]                   
                    *       at least 80% of our net assets in municipal
                    obligations the interest on which is exempt from
                    federal income tax and not subject to the federal
                    alternative minimum tax; and     
                        
                    *       in obligations rated within the two highest
                    categories by a nationally recognized ratings 
                    organization.     
    
                    We may also invest up to 20% of our assets in permitted
                    taxable investments as a defensive measure due to unusual
                    market conditions or to maintain liquidity.

[LOGO OF AN         Important Risk Factors 
EXCLAMATION         You should consider both the General Investment Risks
POINT]              beginning on page 18 and the specific risks listed below.
                    They are both important to your investment choice.     
                    
                    Up to 25% or more of our assets invested in municipal
                    obligations may be related in such a way that political,
                    economic or business developments affecting one obligation
                    would affect the others. For example, we may own different
                    obligations that pay interest based on the revenue of
                    similar projects.     
    
                    There is no guarantee that we will be able to maintain a
                    $1.00 per share net asset value. 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. No government agency
                    either directly or indirectly insures or guarantees the
                    performance of the Fund.

[LOGO OF A RIGHT    Investment Objective
POINT ARROW]        The Prime Money Market Mutual Fund seeks to provide
                    investors with maximized current income to the extent
                    consistent with preservation of capital and maintenance of
                    liquidity.
        
                    Investment Policies
                    We pursue this objective by actively managing a portfolio
                    consisting of a broad range of U.S. dollar-denominated, high
                    quality money market instruments, including debt obligations
                    with remaining maturities of 397 days or less. We maintain
                    an overall dollar-weighted average maturity of 90 days or
                    less. We may also make certain other investment including,
                    for example, repurchase agreements.

[LOGO OF A RIGHT    Important Risk Factors
POINT ARROW]        You should consider both the General Investment Risks
                    beginning on page 18 and the specific risks listed below.
                    They are both important to your investment choice.     

                    There is no guarantee that we will be able to maintain a
                    $1.00 per share net asset value. 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. No government agency
                    either directly or indirectly insures or guarantees the
                    performance of the Fund.

[LOGO OF            Investment Objective

                    The Treasury Money Market Mutual Fund seeks to provide
                    investors with current income and stability of principal.

                    Investment Policies
    
                    We actively manage a portfolio composed of obligations
                    issued or guaranteed by the U.S. Treasury. We also invest
                    in notes, repurchase agreements and other instruments
                    collateralized or secured by Treasury obligations. We buy
                    obligations with remaining maturities of 397 days or less.
                    We maintain an overall dollar-weighted average maturity of
                    90 days or less.     
______________________________________________________________________________
    
[LOGO OF            Permitted Investments
PERCENTAGE SIGN] 
                    Under normal market conditions, we invest:     
                     
                    *       in U.S. Treasury obligations; and     
                    *       in repurchase agreements collateralized by U.S.
                    Treasury obligations.

                    As a temporary defensive measure, or to maintain
                    liquidity, we may invest in shares of other money market
                    funds that have similar investment objectives.

[LOGO OF AN         Important Risk Factors
EXCLAMATION POINT]  You should consider both the General Investment Risks
                    beginning on page 18 and the specific risks listed below.
                    They are both important to your investment choice.     

                    There is no guarantee that we will be able to maintain a
                    $1.00 per share net asset value. 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. The U.S.
                    Treasury does not directly or indirectly insure or
                    guarantee the performance of the Fund.                   
_______________________________________________________________________________

[LOGO OF A          Additional Fund Facts
RIGHT PLUS SIGN]    Treasury obligations have historically involved little
                    risk of loss of principal if held to maturity. However,
                    fluctuations in market interest rates may cause the market
                    value of Treasury obligations in the Fund's portfolio to
                    fluctuate.

General Investment Risks
- -------------------------------------------------------------------------------
    
Understanding the risks involved in mutual fund investing will help you make an
informed decision that takes into account your tolerance and preferences. You
should carefully consider risks common to all mutual funds, including the
Stagecoach Funds. Chief among these risks are the following:    

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

*  We cannot guarantee we will meet our investment objectives. In particular,
   we cannot guarantee that we will be able to maintain a $1.00 per share net
   asset value.
    
*  You cannot recover through insurance any loss due to investment practices,
   nor can the Fund, the Institutions or investment advisors "make good" any
   losses you might have.     

*  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 invest in debt securities, such as notes and bonds, that are
   subject to credit risk and interest rate risk. Credit risk is the
   possibility that an issuer of a security 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 possibility that interest rates may increase and
   reduce the resale value of securities in a Fund's portfolio. Debt
   securities with longer maturities are generally more sensitive to interest
   rate changes than those with shorter maturities. Interest rate risk does
   not affect the interest paid by a debt security unless it is specifically
   designed to pay an adjustable rate.     
    
*  The Funds' advisor may also use certain derivative instruments such as
   options or futures contracts. The term "derivatives" covers a wide range 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 following types of floating-rate derivative securities are NOT permitted
investments in the Funds:

*  Capped floaters on which interest is not paid when market rates move above
   a certain level;

*  Leveraged floaters whose interest rates reset based on a formula that
   magnifies changes in market interest rates;

18      Stagecoach Money Market Funds Prospectus
<PAGE>
 
- --------------------------------------------------------------------------------

*  Range floaters on which interest is not paid if market interest rates move
   outside a specified range;

*  Dual index floaters whose interest rate reset provisions are tied to more
   than one index; and
    
*  Inverse floaters which have interest rates that reset in an opposite
   direction of their index.     

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. Additional
information about these practices is available in the Statement of Additional
Information.     
    
Counter-Party Risk- The risk that the other party in a repurchase agreement or
other transaction will not fulfill its contract obligation.     
    
Credit Risk- The risk that the issuer of a debt security will be unable to
make interest payments or repay principal on schedule. If an issuer does
default, the affected security could lose all of its value, or be renegotiated
at a lower interest rate or principal amount. Affected securities might also
lose liquidity. Credit risk also includes the risk that a party in a
transaction may not be able to complete the transaction as agreed.     

Diplomatic Risk- The risk that an adverse change in the diplomatic relations
between the United States and another country might reduce the value or
liquidity of investments in either country.
    
Information Risk- The risk that information about a security is either
unavailable, incomplete or is inaccurate.     

Interest Rate Risk- The risk that changes in interest rates can reduce the
value of an existing security. Generally, when interest rates increase, the
value of a debt security decreases. The effect is usually more pronounced for
securities with longer dates to maturity.
    
Leverage Risk- The risk that a practice may increase a Fund's exposure to
Market Risk, Interest Rate Risk or other risks by, in effect, increasing
assets available for investment.     

Liquidity Risk- The risk that a security cannot be sold, or cannot be sold
without adversely affecting its fair price.
<PAGE>
 
General Investment Risks
- --------------------------------------------------------------------------------
    
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.

    
  -----------------------------------------------------------------------------
  Investment Practice/Risk

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

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

  Remember, each Fund is designed to meet different investment needs and has a
  different investment objective and investment policies. Each Fund engages in
  the investment practices described below to varying degrees.

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

         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
         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. Therefore, we may pay the redemption in part
         or in whole in securities of equal value.

Exchanges
- --------------------------------------------------------------------------------
    
Exchanges between Stagecoach Funds are two transactions: a sale of one Fund and
the purchase of another. In general, the same rules and procedures that apply to
sales and purchases apply to exchanges. There are, however, additional factors
you should keep in mind while making or considering an exchange:     
    
*        You should carefully read the Prospectus for the Fund into which you
         wish to exchange.     

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

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

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

*        In order to discourage excessive Fund transaction expenses that must
         be borne by other shareholders, we reserve the right to limit or
         reject exchange orders. Generally, we will notify you 60 days in
         advance of any changes in your exchange privileges.
    
*        Institutional Class shares may be exchanged for other Institutional
         Class shares, or for Class A shares in certain qualified accounts.
         Contact your account representative for further details.

Dividend and Capital Gain Distributions     
    
Distributions paid by a Fund are automatically reinvested to purchase new
shares of the Fund. The new shares are purchased at NAV, generally on the day
the 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 substitute for careful tax planning. You should consult
your tax advisor about your specific tax situation. Federal income tax
considerations are discussed further in the Statement of Additional
Information.     
    
We will pass on to you net investment income and net short-term capital gains
earned by a Fund as dividend distributions. These are taxable to you as
ordinary income. However, dividends distributed by the National Tax-Free Money
Market Mutual Fund which are attributable to the Fund's net interest income
from tax-exempt securities will not be subject to federal income tax.     
    
We will pass on to you any net capital gains earned by a Fund as a capital
gain distribution. In general, these distributions will be taxable to you as
long-term capital gains and are taxable when paid. However, distributions
declared in October, November and December and distributed by the following
January will be taxable as if they were paid on December 31 of the year in
which they were declared. We will notify you as to the status of your Fund
distributions.     
    
Your redemptions, including exchanges, will ordinarily result in a taxable
capital gain or loss, depending on the amount you receive for your shares and
the amount you paid for them. Foreign shareholders may be subject to different
tax treatment, including withholding. In certain circumstances, U.S. residents
will be subject to back-up withholding.

How to Read the Financial Highlights
- --------------------------------------------------------------------------------
    
After the description of each Fund there is a chart showing important
financial information about the Fund. The chart is called the "Financial
Highlights" and is designed to help you understand the past performance of the
Fund. The financial statements from which the Financial Highlights were
derived were audited by KPMG Peat Marwick LLP, except as indicated. The
financial statements are included in each Fund's most recent Annual or Semi-
Annual Report and are available free of charge by calling 1-800-260-5969.
Other auditors audited the financial statements for the Arizona Tax-Free,
National Tax-Free and Oregon Tax-Free Funds for periods prior to October 1,
1995.     
    
Here is an explanation of some terms that will help you read these charts.      
    
Net Asset Value (NAV)- The net value of one share of a class of a Fund. See
the Glossary for a fuller definition.     
    
Net Investment Income- Net investment income is calculated by subtracting the
aggregate Fund expenses from the Fund's investment income. The number in the
financial highlights is the net investment income of a class divided by the
number of outstanding shares of that class. The amount distributed to
shareholders is listed under the heading "Less Distributions-Dividends from
Net Investment Income."     
    
Net Realized and Unrealized Gain (Loss) on Investments- We continually buy and
sell investments. The profit on an investment sold for more than its purchase
price is a realized capital gain while a loss on an investment sold for less
than its purchase price is a realized capital loss. An unrealized gain or loss
occurs when an investment gains or loses value but is not sold. The amount of
capital gain or loss per share that was paid to shareholders is listed under
the heading "Less Distributions-Distributions From Net Realized Gains."     
    
Net Assets- The value of the investments in a Fund's portfolio (after
accounting for expenses) that are attributable to a particular class of the
Fund.     
    
Ratio of Expenses to Average Net Assets- This ratio reflects the amount paid
by a Fund to cover the costs of its daily operations, and includes advisory,
administration and other operating expenses. It is expressed as a percentage
of the average daily net assets of a class.     
    
Ratio of Net Investment Income (Loss) to Average Net Assets- This ratio is the
result of dividing net investment income (or loss) by average net assets.
