KEY INFORMATION

WHAT ARE THE FUNDS' GOALS?

The STRONG HERITAGE MONEY FUND, STRONG INVESTORS MONEY FUND, and STRONG MONEY
MARKET FUND seek current income, a stable share price, and daily liquidity.

The STRONG MUNICIPAL MONEY MARKET FUND seeks federally tax-exempt current
income, a stable share price, and daily liquidity.

The STRONG ADVANTAGE FUND seeks current income with a very low degree of
share-price fluctuation.

The STRONG MUNICIPAL ADVANTAGE FUND seeks federally tax-exempt current income
with a very low degree of share-price fluctuation.

WHAT ARE THE FUNDS' PRINCIPAL INVESTMENT STRATEGIES?

The HERITAGE MONEY FUND, INVESTORS MONEY FUND, and MONEY MARKET FUND are
managed to provide attractive yields and a stable share price of $1.00. They
invest in a portfolio of high-quality, short-term debt securities issued by
corporations, banks, and other financial institutions.

The MUNICIPAL MONEY MARKET FUND is managed to provide attractive yields and a
stable share price of $1.00.  It invests in a portfolio of high-quality,
short-term debt securities primarily issued by states and their political
subdivisions, such as municipalities.

The managers may sell a holding if its fundamental qualities deteriorate, or to
take advantage of more attractive yield opportunities.

The ADVANTAGE FUND invests primarily in very short-term, corporate, and
mortgage- and asset-backed bonds. The fund invests primarily in higher- and
medium-quality bonds. To enhance its return potential, the fund also invests a
portion of its assets in bonds that have longer maturities or are of
lower-quality (high-yield or junk bonds), though it may not invest in bonds
rated below BB.  The managers focus upon high-yield bonds rated BB with
positive or improving credit fundamentals. To help limit changes in share
price, the fund's average maturity is usually one year or less.

The MUNICIPAL ADVANTAGE FUND invests primarily in very short-term municipal
bonds. The fund invests primarily in higher and medium quality municipal bonds.
To enhance its return potential, the fund also invests a portion of its assets
in bonds that have longer maturities or are of lower-quality (high-yield or
junk bonds), though it may not invest in bonds rated below BB.  The manager
focuses upon high-yield bonds rated BB with positive or improving credit
fundamentals. To help limit changes in share price, the fund's average maturity
is usually one year or less.

For the ADVANTAGE FUND and MUNICIPAL ADVANTAGE FUND, the managers may sell a
holding if its value becomes unattractive.  Also, the managers may invest any
amount in cash or cash-type securities as a temporary defensive position to
avoid losses during adverse market conditions.  This could reduce the benefit
to the funds if the market goes up.  In this case, the funds may not achieve
their investment goal.  The funds were designed for investors who seek higher
yields than those generally offered by money market funds and who are willing
to accept some modest share-price fluctuation to achieve that objective.

The MUNICIPAL MONEY MARKET and the MUNICIPAL ADVANTAGE FUNDS invest in
municipal bonds whose interest may be subject to the federal alternative
minimum tax (AMT).

((Side Box))
Under normal market conditions, the MUNICIPAL MONEY MARKET and the MUNICIPAL
ADVANTAGE FUNDS will invest at least 80% of their assets in municipal bonds.
MUNICIPAL BONDS are debt obligations issued by or for U.S. states, territories,
and possessions and the District of Columbia and their political subdivisions,
agencies, and instrumentalities.  Municipal bonds can be issued to obtain money
for public purposes or for privately operated facilities or projects.  Some
municipal bonds pay interest which is exempt from federal income tax.  Examples
of municipal bonds are general obligation bonds, revenue bonds, industrial
development bonds, notes, and municipal lease obligations.

WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUNDS?


FOR THE HERITAGE MONEY, INVESTORS MONEY, MONEY MARKET, AND MUNICIPAL MONEY
MARKET FUNDS (MONEY MARKET FUNDS):

NOT INSURED: Your investment in the money market funds is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
government agency.  Each fund's goal is to preserve the value of your
investment at $1.00 per share. However, it is possible to lose money by
investing in these funds.

The money market funds are appropriate for investors who are comfortable with
the risks described here and who need cash immediately.  They can also be used
as a permanent conservative part of your portfolio.

FOR THE ADVANTAGE AND MUNICIPAL ADVANTAGE FUNDS (BOND FUNDS):
BOND RISKS: The major risks of each bond fund are those of investing in the
bond market. A bond's market value is affected significantly by changes in
interest rates-generally, when interest rates rise, the bond's market value
declines and when interest rates decline, its market value rises (interest-rate
risk).  Generally, the longer a bond's maturity, the greater the risk and the
higher its yield. Conversely, the shorter a bond's maturity, the lower the risk
and the lower its yield (maturity risk). A bond's value can also be affected by
changes in the bond's credit-quality rating or its issuer's financial condition
(credit-quality risk). Because bond values fluctuate, the fund's share price
fluctuates. So, when you sell your investment, you may receive more or less
money than you originally invested.

HIGH-YIELD BONDS: Each of the bond funds invest a limited portion of their
assets in medium- and lower-quality bonds, including high-yield bonds (commonly
referred to as junk bonds). Lower-quality bonds involve greater interest-rate
and credit-quality risks than higher- and medium-quality bonds. High-yield
bonds possess an increased possibility that the bond's issuer may not be able
to make its payments of interest and principal. If that happens, the fund's
share price would decrease and its income distributions would be reduced.  An
economic downturn or period of rising interest rates could adversely affect the
high-yield bond market and reduce the fund's ability to sell its high-yield
bonds (liquidity risk).  A lack of a liquid market for these bonds could
decrease the fund's share price.

FOREIGN SECURITIES: The ADVANTAGE FUND may invest up to 25% of its assets in
foreign securities.  Foreign investments involve additional risks including
currency-rate fluctuations, political and economic instability, differences in
financial reporting standards, and less-strict regulation of securities
markets.

MORTGAGE- AND ASSET-BACKED SECURITIES: The ADVANTAGE FUND and MUNICIPAL
ADVANTAGE FUND invest in mortgage-backed and asset-backed securities.  These
securities are subject to prepayment risk, which is the risk that the borrower
will prepay some or all of the principal owed to the issuer. If that happens,
the fund may have to replace the security by investing the proceeds in a less
attractive security.  This could reduce the fund's share price and its income
distributions.

The share price of each of the bond funds will vary.  The ADVANTAGE FUND and
MUNICIPAL ADVANTAGE FUND are not appropriate for investors concerned primarily
with principal stability.

FUND STRUCTURE
Although each of the funds has adopted a multiple class plan, only the
ADVANTAGE FUND offers multiple classes of shares:  Investor Class shares,
Institutional Class shares, and Advisor Class shares. The HERITAGE MONEY,
INVESTORS MONEY, MONEY MARKET, MUNICIPAL MONEY MARKET, and MUNICIPAL ADVANTAGE
FUNDS offer only Investor Class shares.  Only the Investor Class shares of each
fund are offered in this prospectus. The principal difference between each of
the classes of shares is that the Advisor Class shares are subject to
distribution fees and expenses under a 12b-1 plan and that each class of shares
is subject to different administrative and transfer agency fees and expenses.

FUND PERFORMANCE
The return information on the next page illustrates how the performance of the
funds' Investor Class shares can vary, which is one indication of the risks of
investing in the funds. Please keep in mind that the past performance of the
funds' Investor Class shares does not represent how they will perform in the
future.  The information assumes that you reinvested all dividends and
distributions. Only funds with at least one calendar year's performance appear
on the next page.

WHAT ARE THE FUNDS' FEES AND EXPENSES?

This section describes the fees and expenses that you may pay if you buy and
hold shares of the funds.

SHAREHOLDER FEES
(fees paid directly from your investment)
All of the Strong Funds are 100% no-load, so you pay no sales charges (loads)
to buy or sell shares.

ANNUAL FUND OPERATING EXPENSES
(expenses that are deducted from fund assets)
The costs of operating the funds are deducted from fund assets, which means you
pay them indirectly. These costs are deducted before computing the daily share
price or making distributions. As a result, they don't appear on your account
statement, but instead reduce the total return you receive from your fund
investment.

YEAR 2000 ISSUES
Your investment could be adversely affected if the computer systems used by the
funds, Strong, and the funds' service providers do not properly process and
calculate date-related information before, on, and after January 1, 2000.  Year
2000-related computer problems could have a negative impact on your fund and
the fund's investments, however, we are working to avoid these problems and to
obtain assurances from our service providers that they are taking similar
steps.  Please note that Year 2000-related computer problems may have a greater
negative impact on foreign capital markets and foreign investments, especially
in emerging markets.

A WORD ABOUT CREDIT QUALITY

CREDIT QUALITY measures the issuer's expected ability to pay interest and
principal payments on time.  Credit quality can be "higher-quality",
"medium-quality", "lower-quality", or "in default".

HIGHER-QUALITY means bonds that are in any of the three highest rating
categories.  For example, bonds rated AAA to A by Standard & Poor's Ratings
Group (S&P)*.

MEDIUM-QUALITY means bonds that are in the fourth-highest rating category.  For
example, bonds rated BBB by S&P*.

LOWER-QUALITY means bonds that are below the fourth-highest rating category.
They are also known as non-investment, high-risk, high-yield, or "junk bonds".
For example, bonds rated BB to C by S&P*.

IN DEFAULT means the bond's issuer has not paid principal or interest on time.

* OR THOSE RATED IN THIS CATEGORY BY ANY NATIONALLY RECOGNIZED STATISTICAL
RATING ORGANIZATION.  S&P IS ONLY ONE EXAMPLE OF A NATIONALLY RECOGNIZED
STATISTICAL RATING ORGANIZATION.

This chart shows S&P's definition and ratings group for credit quality.  Other
rating organizations use similar definitions.

<PAGE>

We determine a bond's credit quality rating at the time of investment by
conducting credit research and analysis and by relying on credit ratings of
several nationally recognized statistical rating organizations.  These
organizations are called NRSROs. When we determine if a bond is in a specific
category, we may use the highest rating assigned to it by any NRSRO. If a bond
is not rated, we rely on our credit research and analysis to rate the bond.  If
a bond's credit-quality rating is downgraded after our investment, we monitor
the situation to decide if we need to take any action such as selling the bond.

Typically, municipal bonds are not rated. This means that investments in
municipal bonds may require more credit analysis by us than investments in
taxable bonds.  Also, investments in lower-quality bonds (junk bonds) will be
more dependent on our credit analysis than would be higher-quality bonds
because, while lower-quality bonds generally offer higher yields than
higher-quality bonds with similar maturities, lower-quality bonds involve
greater risks.  These include the possibility of default or bankruptcy because
the issuer's capacity to pay interest and repay principal is considered
predominantly speculative.  Also, lower-quality bonds are less liquid, meaning
that they may be harder to sell than bonds of higher quality because the demand
for them may be lower and there are fewer potential buyers. This lack of
liquidity may lower the value of the fund and your investment.

TAXABLE INVESTMENTS

The MUNICIPAL MONEY MARKET FUND and the MUNICIPAL ADVANTAGE FUND may invest up
to 20% of their net assets in U.S. government and corporate bonds, and other
debt securities that are of the same quality as the fund's investments in
municipal bonds.  The MUNICIPAL ADVANTAGE FUND will generally invest in these
bonds to take advantage of capital gain opportunities.  These bonds produce
taxable income, unlike municipal bonds which generally provide tax-exempt
income.

IF YOU ARE SUBJECT TO THE ALTERNATIVE MINIMUM TAX

The MUNICIPAL MONEY MARKET FUND and the MUNICIPAL ADVANTAGE FUND may invest,
without limitation, in municipal obligations whose interest is a tax-preference
item for purposes of the federal alternative minimum tax (AMT).  If you are
subject to the AMT, a substantial portion of your fund's distributions to you
may not be exempt from federal income tax. If this is the case, a fund's net
return to you may be lower.

FINANCIAL HIGHLIGHTS

This information describes investment performance of the Investor Class shares
of the funds for the periods shown. Certain information reflects financial
results for a single Investor Class share.  "Total Return" shows how much an
investment in the Investor Class shares of the fund would have increased (or
decreased) during each period, assuming you had reinvested all dividends and
distributions.  These figures have been audited by PricewaterhouseCoopers LLP,
whose report, along with the fund's financial statements, is included in the
fund's annual report.

YOUR ACCOUNT

All of the Strong Funds are 100% no-load.  This means that you may purchase,
redeem, or exchange shares directly at their net asset value without paying a
sales charge.

SHARE PRICE

Your transaction price for buying, selling, or exchanging shares of the funds
or the Investor Class of the Advantage Fund is the net asset value per share
(NAV) for that fund or class of shares.  NAV is generally calculated as of the
close of trading on the New York Stock Exchange (usually 3:00 p.m. Central
Time) every day the NYSE is open.  If the NYSE closes at any other time, or if
an emergency exists, NAV may be calculated at a different time.  Your share
price will be the next NAV calculated after we accept your order.

For the money market funds, we use amortized cost to value money market
securities held by a fund.

((Side Box))
<TABLE>
<CAPTION>
<S>                               <C>
When we use AMORTIZED COST to value money market
fund securities, we generally mean that the security is
initially valued at the price we paid for it.  After that, the
value of the security is gradually increased (amortizing a
discount) or decreased (amortizing a premium) each day
without regard to fluctuating interest rates.
- --------------------------------------------------------------
</TABLE>

For the bond funds, NAV is based on the market value of the securities in a
fund's portfolio.  If market prices are not available, NAV is based on a
security's fair value as determined in good faith by us under the supervision
of the Board of Directors of the Strong Funds.

FOREIGN SECURITIES
Some of the bond funds' portfolio securities may be listed on foreign exchanges
that trade on days when we do not calculate an NAV.  As a result, the market
value of securities in a fund's portfolio may change on days when you will not
be able to purchase or redeem shares.  In addition, a foreign exchange may not
value its listed securities at the same time that we calculate a fund's NAV.
Events affecting the values of portfolio securities that occur between the time
a foreign exchange assigns a price to the portfolio securities and the time
when we calculate a fund's NAV generally will not be reflected in the fund's
NAV.  These events will be reflected in the fund's NAV when we, under the
supervision of the Board of Directors of the Strong Funds, determine that they
would have a material effect on the fund's NAV.

((Side Box))
<TABLE>
<CAPTION>
<S>                                  <C>
We determine the share price or NAV of a fund or class
by dividing net assets attributable to the fund or class
(the value of the investments, cash, and other assets
attributable to the fund or class minus the liabilities
attributable to the fund or class) by the number of fund
or class shares outstanding.

PLEASE REMEMBER ...
- - If you use an Automatic Investment Plan, we waive the initial investment
  minimum to open an account and the additional investment minimum is $50.
  This waiver does not apply to the HERITAGE MONEY FUND.

- - You cannot use an Automatic Investment Plan with an Education IRA.

- - If you open a qualified retirement plan account where we or one of our
  alliance partners provides administrative services, there is no initial
  investment minimum, except for the HERITAGE MONEY FUND which is $25,000.

- - For the INVESTORS MONEY FUND:
- - You may only open one regular account.  You may not make additional purchases
  after your account reaches $50,000.  If you participate in an Automatic
  Investment Plan, we will discontinue the plan after your account reaches
  $50,000.
- - You may open up multiple IRA accounts.  You may not make additional purchases
  into your IRA accounts once the aggregate value of all of your IRA accounts
  in the fund reaches $50,000.  If you participate in an Automatic Investment
  Plan, we will discontinue the plan after the value of your IRA accounts
  reaches $50,000.

The ADVANTAGE FUND has adopted a multiple class plan which currently permits it
to offer three classes of shares:  Investor Class shares, Institutional Class
shares, and Advisor Class shares.  The HERITAGE MONEY, INVESTORS MONEY, MONEY
MARKET, MUNICIPAL MONEY MARKET, and MUNICIPAL ADVANTAGE FUNDS each have adopted
a multiple class plan that currently permits each fund to offer only Investor
Class shares.  Each class is offered at its net asset value without the
imposition of any sales load, however, each class of shares is subject to fees
and expenses which may differ. The principal difference between each of the
classes of shares is that the Advisor Class shares are subject to distribution
fees and expenses under a 12b-1 plan and that each class of shares is subject
to different administrative and transfer agency fees and expenses.

 ADDITIONAL POLICIES

 TELEPHONE TRANSACTIONS
 Once you place a telephone transaction request, it cannot be canceled or
 modified. We use reasonable procedures to confirm that telephone transaction
 requests are genuine.  We may be responsible if we do not follow these
 procedures.  You are responsible for losses resulting from fraudulent or
 unauthorized instructions received over the telephone, provided we reasonably
 believe the instructions were genuine. During times of unusual market
 activity, our phones may be busy and you may experience a delay placing a
 telephone request. During these times, consider trying STRONG DIRECT(R), our
 24-hour automated telephone system, by calling 1-800-368-7550, or STRONG
 NETDIRECT(R), our on-line transaction center, by visiting WWW.ESTRONG.COM.
 Please remember that you must have telephone redemption as an option on your
 account to redeem shares through STRONG DIRECT(R) or STRONG NETDIRECT(R).

 INVESTING THROUGH A THIRD PARTY
 If you invest through a third party (rather than directly with Strong Funds),
 the policies and fees may be different than described in this prospectus.
 Banks, brokers, 401(k) plans, financial advisors, and financial supermarkets
 may charge transaction fees and may set different minimum investments or
 limitations on buying or selling shares.  Consult a representative of your
 plan or financial institution if you are not sure.

 HERITAGE MONEY FUND ACCOUNT MAINTENANCE AND TRANSACTION FEES
 For the HERITAGE MONEY FUND, a $3 fee will be charged for each exchange,
 redemption, or check transaction. A $3 quarterly account maintenance fee is
 also charged if the balance in your HERITAGE MONEY FUND is less than $25,000.
 HOWEVER, WE WILL WAIVE THESE FEES IF YOUR COMBINED STRONG FUNDS' ACCOUNT
 BALANCE IS $100,000 (OR HIGHER) AT THE END OF THE QUARTER DURING WHICH, (1)
 YOU EXCHANGED, REDEEMED OR WROTE A CHECK, OR (2) YOUR ACCOUNT BALANCE FELL
 BELOW $25,000.

 DISTRIBUTIONS

 DISTRIBUTION POLICY
 Each fund generally pays you dividends from net investment income monthly and
 distributes any net capital gains that it realizes annually.  Dividends are
 declared on each day NAV is calculated, except for bank holidays. Dividends
 earned on weekends, holidays, and days when the fund's NAV is not calculated
 are declared on the first day preceding these days that the fund's NAV is
 calculated.  Your investment generally earns dividends from the first business
 day after we accept your purchase order.

                                      15
<PAGE>

 REINVESTMENT OF DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS
 Your dividends and capital gain distributions will be automatically reinvested
 in additional shares, unless you choose otherwise.  Your other options are to
 receive checks for these payments, have them automatically invested in another
 Strong Fund, or have them deposited into your bank account. To change the
 current option for payment of dividends and capital gains distributions,
 please call 1-800-368-3863.

 TAXES

 TAXABLE DISTRIBUTIONS
 Any net investment income and net short-term capital gain distributions you
 receive are taxable as ordinary dividend income at your income tax rate.
 Distributions of net capital gains are generally taxable as long-term capital
 gains.  This is generally true no matter how long you have owned your shares
 and whether you reinvest your distributions or take them in cash. You may also
 have to pay taxes when you exchange or sell shares if your shares have
 increased in value since you bought them.

 TAX-EXEMPT DISTRIBUTIONS
 Exempt-interest dividends from municipal funds are generally exempt from
 federal income taxes, but may be subject to state and local tax. Also, if you
 are subject to the Alternative Minimum Tax, you may have to pay federal tax on
 a portion of your income from exempt-interest dividends.

  ((Side Box))
<TABLE>
<CAPTION>
<S>                                 <C>
Generally, if your investment is in a Traditional IRA or
other TAX-DEFERRED ACCOUNT, your dividends and
distributions will not be taxed at the time they are paid,
but instead at the time you withdraw them from your
account.
- ----------------------------------------------------------
</TABLE>

 RETURN OF CAPITAL
 If your fund's (1) income distributions exceed its net investment income and
 net short-term capital gains or (2) capital gain distributions exceed its net
 capital gains in any year, all or a portion of those distributions may be
 treated as a return of capital to you. Although a return of capital is not
 taxed, it will reduce the cost basis of your shares.

 YEAR-END STATEMENT
 To assist you in tax preparation, after the end of each calendar year, we send
 you a statement of your fund's ordinary dividends and net capital gain
 distributions (Form 1099).

 BACKUP WITHHOLDING
 By law, we must withhold 31% of your distributions and proceeds if (1) you are
 subject to backup withholding or (2) you have not provided us with complete
 and correct taxpayer information such as your Social Security Number (SSN) or
 Tax Identification Number (TIN).

Unless your investment is in a tax-deferred retirement
account such as an IRA, you may want to avoid selling
shares of a mutual fund at a loss and then investing in the
same fund within 30 days before or after the sale.  This is
called a WASH SALE and you will not be allowed to claim a
tax loss on the transaction.

COST BASIS is the amount that you paid for the shares.
When you sell shares, you subtract the cost basis from the
sale proceeds to determine whether you realized an
investment gain or loss.   For example, if you bought a
share of a fund at $10 and you sold it two years later at
$11, your cost basis on the share is $10 and your gain is
$1.

 it before investing in any of the Strong Funds.  Remember, an exchange of
 shares of one Strong Fund for those of another Strong Fund is considered a
 sale and a purchase of fund shares for tax purposes and may result in a
 capital gain or loss. Some Strong Funds that you may want to exchange into may
 charge a redemption fee of 0.50% to 1.00% on the sale of shares held for less

 requirements and other criteria of the fund purchased.

 RESERVED RIGHTS

 We reserve the right to:

- - Refuse, change, discontinue, or temporarily suspend account services,
  including purchase, exchange, or telephone and netDirect(R) redemption
  privileges, for any reason.

- - Reject any purchase request for any reason including exchanges from other
  Strong Funds.  Generally, we do this if the purchase or exchange is
  disruptive to the efficient management of a fund (due to the timing of the
  investment or an investor's history of excessive trading).

- - Change the minimum or maximum investment amounts.

- - Delay sending out redemption proceeds for up to seven days (this generally
  only applies to very large redemptions without notice, excessive trading, or
  during unusual market conditions).

- - Suspend redemptions or postpone payments when the NYSE is closed for any
  reason other than its usual weekend or holiday closings, when trading is
  restricted by the SEC, or under any emergency circumstances.

- - Make a redemption-in-kind (a payment in portfolio securities rather than
  cash) if the amount you are redeeming is in excess of the lesser of (1)
  $250,000 or (2) 1% of the fund's assets. Generally, redemption-in-kind is
  used when large redemption requests may cause harm to the fund and its
  shareholders.  This includes redemptions made by checkwriting.

- - Close any account that does not meet minimum investment requirements.  We
  will give you notice and 60 days to begin an automatic investment program or
  to increase your balance to the required minimum.

- - Reject any purchase or redemption request that does not contain all required
  documentation.

 Additionally, with the STRONG INVESTORS MONEY FUND, we reserve the right to:

- - Redeem shares in your regular account that exceed $50,000 (exclusive of
  dividends).

- - Redeem shares in your IRA accounts that, in the aggregate, exceed $50,000
  (exclusive of dividends).

- - Close accounts and redeem all shares in the accounts if you have more than
  one regular account.

- - Reverse purchase orders that caused the value of your account to exceed
  $50,000 (exclusive of dividends).
