The Commerce Funds

What These Funds Are: These Funds are mutual funds. A mutual fund is a pooled
investment that gives you an opportunity to participate in financial markets.
Each Fund is professionally managed. Each Fund has stated goals that it
attempts to reach. However, as with all mutual funds, neither of these Funds
can offer guaranteed results. You could lose money in these Funds.
The Commerce Funds consists of nine investment portfolios, each of which has a
separate pool of assets with separate investment objectives and policies. This
Prospectus offers Service Shares of two of these investment portfolios.

The National Tax-Free Intermediate Bond Fund seeks current income exempt from
federal income tax as is consistent with the preservation of capital.

The Missouri Tax-Free Intermediate Bond Fund seeks current income exempt from
federal and, to the extent possible, from Missouri income taxes, as is
consistent with the preservation of capital.

What These Funds Are Not: An investment in either of these Funds is not a bank
deposit. Your investment is not insured or guaranteed by the FDIC or any other
agency of the government.

<PAGE>

This Prospectus describes the Service Shares of each Fund. Service Shares are
offered primarily to:

. individuals, corporations or other entities, purchasing for their own
accounts or for the accounts of others, and to qualified banks, savings and
loan associations, and broker/dealers on behalf of their customers; and

. financial planners and their clients.

The Commerce Funds is also authorized to issue an additional class of shares,
the Institutional Shares. Institutional Shares are offered primarily to:

. investors maintaining accounts at bank trust departments or trust companies,
for funds held within those accounts, including institutions affiliated with
Commerce Bancshares, Inc. and its subsidiaries (for example, Commerce Bank
Investment Management Group clients), and individuals who have named a bank
affiliated with Commerce Bancshares, Inc., as their primary personal
representative or co-personal representative under will;

. participants in employer-sponsored defined contribution plans when such plans
offer The Commerce Funds as one of their investment options;

. any investor who has been a continuous shareholder in The Commerce Funds
since January 1, 1997 or before;

. employees, directors, advisory directors, officers and retirees (as well as
their spouses and legal dependents) of Commerce Bancshares, Inc., Goldman,
Sachs & Co., State Street Bank and Trust Company and National Financial Data
Services, Inc. or their subsidiaries or affiliates; and

. financial planners, broker/dealers and their clients.

Duration is a linear measure of interest rate risk. For example, a portfolio
with a duration of 2 years would lose 2% of its value if interest rates rose by
1%, or it would gain 2% if interest rates declined by 2%. A portfolio with a
duration of 4 years would be twice as volatile as a portfolio with a duration
of 2 years.

Please see the table on p.14 for more detailed information about the investment
practices of the National Tax-Free Intermediate Bond Fund and the risks
associated with those practices.

Investment Objective
---------------------------------------

Seeks current income exempt from federal income tax consistent with the
preservation of capital.

[GRAPHIC]
Primary Investment Strategies
---------------------------------------

The Fund employs the following strategies in an effort to achieve current
income and capital preservation:
. Security Types: Intends to invest primarily (at least 80%) in investment-
grade municipal bonds issued by or on behalf of the states, territories and
possessions of the United States, the District of Columbia and their
respective authorities, agencies, instrumentalities and political
subdivisions, the interest on which, in the opinion of bond counsel, is
exempt from regular federal income and federal alternative minimum taxes.
. Up to 20% of the Fund's net assets may be invested in municipal obligations
that are not exempt from regular federal income tax.
. Credit Quality: The market-weighted average credit rating of the Fund's
entire portfolio will be AA or better.
. Maturity Distribution: Actively manages maturities to take advantage of
changes in interest rates. The average weighted effective maturity of the
Fund's portfolio securities will be three to ten years, under normal market
conditions.
. The average effective duration of the Fund will be within 30% of the duration
of the Merrill Lynch Municipal Intermediate Index, although the Fund has no
restriction as to the maximum or minimum duration of any individual security
it holds. For example, if the duration of the Merrill Lynch Municipal
Intermediate Index were 5.4 years, the Fund's assets would have a duration of
between 3.78 years and 7.02 years.
. Strives to minimize net realized capital gains.

Primary Risks of Investing in the Fund
-----------------------------------------------------------

Investment Risk: The value of your investment in this Fund may go up or down,
which means that you could lose money.
Interest Rate Risk: Generally, the market value of fixed-income securities can
be expected to go up when interest rates go down and to go down when interest
rates go up.
Market Risk: General economic conditions and/or the activities of individual
companies may cause the value of the securities in the Fund to increase or
decrease.
Credit Risk: An issuer of bonds may default on its obligation to pay interest
and repay principal. Also, a bond's credit rating could be downgraded. The Fund
could lose money in either of these instances.
Management Risk: A strategy used by the Adviser may fail to produce the
intended results.
Municipal Obligation Risk: Payment on municipal obligations held by the Fund
relating to certain projects may be secured by mortgages or deeds of trust. In
the event of a default, enforcement of a mortgage or deed of trust will be
subject to statutory enforcement procedures and limitations on obtaining
deficiency judgments. Moreover, collection of the proceeds from that
foreclosure may be delayed and the amount of the proceeds received may not be
enough to pay the principal or accrued interest on the defaulted municipal
obligations.
Tax Risk: A fund that invests in municipal obligations may be more adversely
impacted by changes in tax rates and policies than other funds.

An investment in the Fund is not a deposit of Commerce Bank and is not insured
or guaranteed by the FDIC or any other governmental agency.

National Tax-Free Intermediate Bond Fund Past Performance
-----------------------------------------------------------

Service Shares of the Fund have less than one calendar year's performance. For
this reason, the performance information shown below is for another class of
shares (Institutional Shares) that is not offered in this Prospectus but would
have similar annual returns because both classes of shares will be invested in
the same portfolio of securities. Annual returns will differ only to the extent
that service shares have a 0.25% distribution (12b-1) fee and, unlike
Institutional Shares, are subject to a maximum sales charge of 2.00%.

The chart and table below provide some indication of the risks of investing in
the Fund by showing the annual returns and long-term performance of the
Institutional Shares. The bar chart shows the Institutional Shares performance
from calendar year to year since its inception. The table compares the
Institutional Shares' performance over time to that of a broad-based securities
market index. Both charts assume reinvestment of dividends and distributions.
As with all mutual funds, how the Institutional Shares of this Fund performed
in the past is not a prediction of how Service Shares will perform in the
future. The performance of the Institutional Shares reflects expense
limitations in effect. If expense limitations were not in place, the
performance of the Institutional Shares would have been reduced.

The following table shows the fees and expenses that you would pay directly or

investment of $1,000,00 or more.
(2) The Adviser has contractually agreed to reduce or limit the Total Annual
Fund Operating Expenses, at least until October 31, 2001 to 0.95% of the
Fund's average daily net assets. The Total Annual Fund Operating Expenses
and Net Annual Fund Operating Expenses of the Fund are estimated based on
expenses expected to be incurred by the Fund in the current fiscal year.

Example: The following example is intended to help you compare the cost of
investing in this Fund with the cost of investing in other mutual funds. It
makes the following assumptions: you invest $10,000 in the Fund for the time
periods indicated, your investment has a 5% return each year, and the Fund's
expenses remain the same. Although your actual costs may be higher or lower,
based on these assumptions your costs would be:

Please see the table on p.14 for more detailed information about the investment
practices of the Missouri Tax-Free Intermediate Bond Fund and the risks
associated with those practices.
[GRAPHIC]
Investment Objective
---------------------------------------

Seeks current income exempt from federal and, to the extent possible, from
Missouri income taxes, as is consistent with the preservation of capital.

[GRAPHIC]
Primary Investment Strategies
---------------------------------------

The Fund employs the following strategies in an effort to achieve current
income and capital preservation:
. Security Types: Normally invests at least 80% of its total assets in
municipal obligations, 65% of which are issued by the State of Missouri and
its political subdivisions, as well as certain other governmental issuers.
. Seeks to maximize the proportion of its dividends that are exempt from both
federal and Missouri income tax.
. Strives to minimize net realized capital gains.
. Credit Quality: The market-weighted average credit rating of the Fund's
entire portfolio will be AA or better.
. Maturity Distribution: Actively manages maturities to take advantage of
changes in interest rates. Under normal market conditions, the average
weighted maturity of the Fund's portfolio securities will be three to ten
years.

[GRAPHIC]
Primary Risks of Investing in the Fund
---------------------------------------

The Commerce Funds PAGE 9
---------------
.
<PAGE>

Missouri Tax-Free Intermediate Bond Fund (continued)
----------------------------------------------------------------------------
Credit Risk: An issuer of bonds may default on its obligation to pay interest
and repay principal. Also, a bond's credit rating could be downgraded. The Fund
could lose money in either of these instances.
Management Risk: A strategy used by the Adviser may fail to produce the
intended results.
State-Specific Risk: The Fund invests its assets predominantly in Missouri
obligations. The actual payment of principal and interest on these obligations
is dependent on the Missouri General Assembly allotting money each fiscal year
for these payments. You should also be aware that provisions of the Missouri
Constitution and other laws could result in certain adverse consequences
affecting Missouri obligations.
Non-Diversified Risk: The Missouri Tax-Free Intermediate Bond Fund is non-
diversified. Non-diversified funds typically hold fewer securities than
diversified funds do. Consequently, the change in value of any one security may
affect the overall value of a non-diversified portfolio more than it would a
diversified portfolio. In addition, a non-diversified portfolio may be more
susceptible to economic, political and regulatory developments than a
diversified investment portfolio with similar objectives. When a Fund's assets
are concentrated in obligations payable from revenues of similar projects
issued by issuers located in the same state, or in industrial development
bonds, the Fund will be subject to the particular risks (including legal and
economic conditions) relating to such securities to a greater extent than if
its assets were not so concentrated.
Tax Risk: A fund that invests in municipal obligations may be more adversely
impacted by changes in tax rates and policies than other funds. Dividends
derived from interest on obligations of other governmental issuers are exempt
from federal income tax but may be subject to Missouri income tax.
Municipal Obligation Risk: Payment on municipal obligations held by the Fund
relating to certain projects may be secured by mortgages or deeds of trust. In
the event of a default, enforcement of a mortgage or deed of trust will be
subject to statutory enforcement procedures and limitations on obtaining
deficiency judgments. Moreover, collection of the proceeds from that
foreclosure may be delayed and the amount of the proceeds received may not be
enough to pay the principal or accrued interest on the defaulted municipal
obligations.

An investment in the Fund is not a deposit of Commerce Bank and is not insured
or guaranteed by the FDIC or any other governmental agency.

this reason, the performance information shown below is for another class of
shares (Institutional Shares) that is not offered in this Prospectus but would
have similar annual returns because both classes of shares will be invested in

Institutional Shares. The bar chart shows the Institutional Shares performance
from calendar year to year since its inception. The table compares the
Institutional Shares' performance over time to that of a broad-based securities
market index. Both charts assume reinvestment of dividends and distributions.
As with all mutual funds, how the Institutional Shares of this Fund performed
in the past is not a prediction of how the Service Shares will perform in the
future. The performance of the Institutional Shares reflects expense
limitations in effect. If expense limitations were not in place, the
performance of the Institutional Shares would have been reduced.

</TABLE>
-----------------------------------------------------------------------------
Credit Risk: An issuer of bonds may default on its obligation to pay interest
and repay principal. A bond's credit rating could be downgraded. A Fund could
lose money in either of these instances.
Interest Rate Risk: Generally, the market value of fixed-income securities in a
Fund can be expected to go up when interest rates go down and to go down when
interest rates go up (although many mortgage related securities will have less
potential than other debt securities for capital appreciation during period of
declining rates). Longer-term bonds and zero coupon bonds are usually more
sensitive to interest rate changes than shorter-term bonds. In general, the
longer the average maturity of bonds in a Fund, the more a Fund's share price
will go up or down in response to interest rate changes.
Investment Risk: The value of your investment in a Fund may go up or down,
which means that you could lose money.
Management Risk: A strategy used by the Adviser may fail to produce the
intended results. The Adviser's assessment of companies whose securities are
held by a Fund may prove incorrect, resulting in losses or poor performance,
even under favorable market and interest rate conditions.
Market Risk: General economic conditions and/or the activities of individual
issuers may cause the value of the securities in a Fund to increase or
decrease. A Fund's NAV may fluctuate with movements in the equity markets.
Municipal Obligation Risk: Payment on municipal obligations held by a Fund
pertaining to certain projects may be secured by mortgages or deeds of trust.
In the event of a default, enforcement of a mortgage or deed of trust will be
subject to statutory enforcement procedures and limitations on obtaining
deficiency judgment. Moreover, collection of the proceeds from the foreclosure
may be delayed and the amount of the proceeds received may not be enough to pay
the principal or accrued interests on the defaulted municipal obligations. The
obligations of the issuer to pay the principal of and interest on a municipal
obligation are subject to the provisions of

PAGE 16 The Commerce Funds
---------------
.
<PAGE>

bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Act, and laws, if any, that may be
enacted by Congress or state legislatures extending the time for payment of
principal or interest or imposing other constraints upon the enforcement of
such obligations. There is also the possibility that, as a result of litigation
or other conditions, the power or ability of the issuer to pay when due the
principal of or interest on a municipal obligation may be materially affected.
Municipal lease obligations and certificates of participation are subject to
the added risk that the governmental lessee will fail to appropriate funds to
enable it to meet its payment obligations under the lease. Although these
obligations may be secured by the leased equipment or facilities, the
disposition of the property in the event of non-appropriation or foreclosure
might prove difficult, time consuming and costly, and result in a delay in
recovering or the failure to fully recover a Fund's original investment.
Non-Diversified Risk: The Missouri Tax-Free Intermediate Bond Fund is non-
diversified. Non-diversified funds typically hold fewer securities than
diversified funds do. Consequently, the change in value of any one security may
affect the overall value of a non-diversified portfolio more than it would a
diversified portfolio. In addition, a non-diversified portfolio may be more
susceptible to economic, political and regulatory developments than a
diversified investment portfolio with similar objectives. When a Fund's assets
are concentrated in obligations payable from revenues of similar projects
issued by issuers located in the same state, or in industrial development
bonds, the Fund will be subject to the particular risks (including legal and
economic conditions) relating to such securities to a greater extent than if
its assets were not so concentrated.
State-Specific Risk: The Missouri Tax-Free Intermediate Bond Fund invests its
assets predominantly in Missouri obligations. The actual payment of principal
and interest on these obligations is dependent on the General Assembly
allotting money each fiscal year for these payments. You should also be aware
that provisions of the State Constitution and other laws could result in
certain adverse consequences affecting these obligations. Increased
urbanization and continued decline in defense appropriations by the U.S.
Congress have had and will continue to have an adverse impact on the State of
Missouri in the forseeable future.
Tax Risk: A Fund that invests in municipal obligations may be more adversely
impacted by changes in tax rates and policies than other Funds. Interest income
on municipal obligations is normally not subject to regular federal income tax.
Any proposed or actual changes in federal income tax rates or exempt statutes
that apply to interest income, therefore, can significantly affect the demand
for and supply, liquidity and marketability of municipal obligations, which
could in turn affect a Fund's ability to buy and sell municipal obligations at
favorable yield and price levels.
Risks of Short-Term Investing: For temporary defensive purposes, the Adviser
may decide to suspend the normal investment activities of a Fund by investing
up to 100% of its assets in cash and cash equivalent short-term obligations,
including money market instruments, a term that includes bank obligations,
commercial paper, U.S. Government

The Commerce Funds PAGE 17
---------------
.
<PAGE>

obligations, foreign government securities (if permitted) and repurchase
agreements. Bank obligations may include obligations of foreign banks or
foreign branches of U.S. banks. The Adviser may temporarily adopt a defensive
position to reduce changes in the value of the Fund's shares that may result
from adverse market, economic, political or other conditions. When the Adviser
pursues a temporary defensive strategy, the Funds may not be following their
stated objectives and may not profit from favorable developments that they
would have otherwise profited from if they were pursuing their normal
investment strategies.
Portfolio Turnover: The Funds may buy and sell investments relatively often.
Such a strategy often involves higher expenses, including brokerage
commissions, and may increase the amount of capital gains (and, in particular,
short-term gains) realized by a portfolio. Shareholders must pay tax on such
capital gains.

Account Policies And Features
--------------------------------------------------------------------------------

The following information is intended to help you understand how to purchase
and redeem shares of The Commerce Funds. It will also explain the features you
can use to customize your Commerce Funds account to meet your needs.

Buying Service Shares
--------------------------------------------------------------------------------

How Are Service Shares Priced?
You pay a sales charge (load) to invest in these Funds. Service Shares of the
Funds are purchased at their public offering price (POP), which is a Fund's net
asset value (NAV) per share plus a front-end sales charge. The NAV is generally
calculated as of the close of trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) every day the NYSE is open. Your order will be
priced at the NAV next calculated after your order is received in good order by
The Commerce Funds' Transfer Agent plus any applicable sales charge. Therefore,
to receive the NAV of any given day, The Commerce Funds must accept your order
by the close of regular trading on the NYSE that day. If The Commerce Funds
receives and accepts your order after the NYSE closes, you will receive the NAV
that is calculated on the close of trading on the following day. The Commerce
Funds are open for business on the same days as the NYSE. Each Fund's
investments are valued based on market value, or where market quotations are
not readily available, based on fair value as determined in good faith by the
Funds' Board of Trustees. Certain short-term securities may be valued at
amortized cost, which approximates fair value.

Trading in foreign securities is generally completed before the end of regular
trading on the NYSE and may occur on weekends and U.S. holidays and at other
times when the NYSE is closed. As a result, there may be delays in reflecting
changes in the market values of foreign securities in the calculation of the
NAV for any Fund invested in foreign securities. You may not be able to redeem
or purchase shares of an affected Fund during these times.

Sales Charge: The maximum front-end sales charge is 2.00% for each Fund and may
be less based on the amount you invest, as shown in the following chart:

* Dealer's reallowance may be changed periodically.
** There is no initial sales charge on purchases of $1,000,000 or more of
Service Shares; however, a contingent deferred sales charge (CDSC) of 1.00%
will be imposed on the lesser of the POP or the NAV of the shares on the
redemption date for shares redeemed within 18 months after purchase.
*** The Distributor may pay placement fees to dealers of up to 1.00% of the
POP on Service Shares purchases of $1,000,000 or more.

. automatic reinvestments and cross reinvestments of dividends and capital gain
distributions;
. the Exchange Privilege described below;
. the Redemption Reinvestment Privilege described below;
. non-profit organizations, foundations and endowments qualified under Section

. registered representatives of dealers who have entered into dealer agreements
with Goldman, Sachs & Co. to the extent permitted by such firms and for their
customers;
. financial planners and their clients;
. customers of Commerce Bank's Investment Management Group (IMG) who purchase

How Do I Buy Service Shares?

The following section describes features and gives specific instructions on how
to purchase Service Shares directly from The Commerce Funds. The Commerce Funds
has authorized certain dealers to purchase shares of Funds on behalf of their
clients. Some of the account features and instructions described in this
section may not be applicable to clients of these dealers.

The Commerce Funds PAGE 21
---------------
.
<PAGE>

1. Consider The Following Features To Customize Your Account:

. Making Automatic Investments: The Automatic Investment feature lets you
transfer money from your financial institution account into your Fund account
automatically either on the 1st or the 15th of the month. The Automatic
Investment feature is one way to use dollar cost averaging to invest (see
below). Only accounts at U.S. financial institutions that permit automatic
withdrawals through the Automated Clearing House (ACH) are eligible. Check
with your financial institution to determine eligibility.

. Using Dollar Cost Averaging: Dollar cost averaging involves investing a
dollar amount at regular intervals. Because more shares are purchased during
periods with lower share prices and fewer shares are purchased when the price
is higher, your average cost per share may be reduced. In order to be
effective, dollar cost averaging should be followed on a regular basis. You
should be aware, however, that shares bought using dollar cost averaging are
made without regard to their price on the day of investment or to market
trends. In addition, while you may find dollar cost averaging to be
beneficial, it will not prevent a loss if you ultimately redeem your shares
at a price that is lower than their purchase price. Dollar cost averaging
does not assure a profit or protect against a loss in a declining market.
Since dollar cost averaging involves investment in securities regardless of
fluctuating price levels, you should consider your financial ability to
continue to purchase through periods of low price levels. You can invest
through dollar cost averaging on your own or through the Automatic Investment
feature described above.

. Using Rights Of Accumulation: When you buy Service Shares of The Commerce
Funds, your current total investment determines the sales charge (load) you
pay. Since larger investments receive a discounted sales charge, the sales
charge (load) you pay may subsequently be reduced as you build your
investment.

To buy Service Shares at a reduced sales charge under Rights of Accumulation,
you must indicate at the time of purchase that a quantity discount is
applicable. (See section 5 of the application.) A reduction in sales charge is
subject to a check of appropriate records, after which you will receive the
lowest applicable sales charge.

Example: Suppose you own Service Shares with a current total value of
$490,000 that can be traced back to the purchase of the shares with a sales
charge. If you subsequently invest $10,000 in any Fund within The Commerce
Funds family, you will pay a reduced sales charge of 1.00% of the POP on the
additional purchase.

. Using Letters Of Intent: You may also buy Service Shares at a reduced sales
charge under a written Letter of Intent, a non-binding commitment to invest a
total of at least $500,000 in one or more Fund of The Commerce Funds within a
period of 13

PAGE 22 The Commerce Funds
---------------
.
<PAGE>

months and under the terms and conditions of the Letter of Intent. Service
Shares you buy under a Letter of Intent will be eligible for the same sales
charge discount that would have been available had all of your Service Shares
been purchased at once. To use this feature, complete the Letter of Intent
section on your account application. A Letter of Intent must be filed with The
Commerce Funds within 90 days of the first investment under the Letter of
Intent provision.

Things To Consider When Completing A Letter Of Intent:
. The Letter of Intent does not bind you to buy or sell shares of the full
amount at the sales charge indicated. However, you must complete the intended
purchase to obtain the reduced sales charge.
. When you sign a Letter of Intent, The Commerce Funds will hold in escrow a
sufficient number of shares which can be sold to make up any difference in
the sales charge on the amount actually invested.
. After you fulfill the terms of the Letter of Intent, the shares in escrow
will be released.
. If your aggregate investment exceeds that indicated in your Letter of Intent,
you will receive an adjustment which reflects the further reduced sales
charge applicable to your excess investment.
. You may combine purchases that are made by members of your immediate family,
or the total investments of a trustee or custodian of any qualified pension
or profit-sharing plan or IRA established for your benefit. Please reference
on the account application the accounts that are to be combined for this
purpose.

What Are My Options For Changing My Investment Within The Commerce Funds?

. Changing Shares From Fund To Fund: As a shareholder, you have the privilege
of exchanging your shares for Service Shares of any other Commerce Fund.
Exchanges may also be made with the Goldman Sachs Institutional Liquid Assets
Prime Obligations Portfolio ("Money Market Fund"). Goldman Sachs Asset
Management, a unit of the Investment Management Division of Goldman, Sachs &
Co., serves as investment adviser for the Money Market Fund.

Service Shares being exchanged are subject to the minimum initial and
subsequent investment requirements as described above. The Commerce Funds
reserves the right to reject any exchange request and the exchange privilege
may be modified or terminated at any time. At least 60 days' notice of any
material modification or termination of the exchange privilege will be given
to shareholders except where notice is not required under the regulations of
the Securities and Exchange Commission (SEC). Before exchanging your shares,
you should consider carefully the investment objectives, policies, risks and
expenses of the Fund you are acquiring.

PAGE 24 The Commerce Funds
---------------
.
<PAGE>

. Making Automatic Exchanges: You may request on your account application that
a specified dollar amount of Service Shares be automatically exchanged for
Service Shares of any other Commerce Fund. These automatic exchanges may be
made on any one day of each month and are subject to the following
conditions: 1) the minimum dollar amount for automatic exchanges must be at
least $250 per month; 2) the value of the account in the originating Fund
must be at least $1,000 after the exchange; 3) the value of the account in
the acquired Fund must equal or exceed the acquired Fund's minimum initial
investment requirement; and 4) the names, addresses and taxpayer
identification number for the shareholder accounts of the exchanged and
acquired Funds must be identical.

.Cross Reinvesting Of Distributions: You may invest dividend or capital gain
distributions from one Fund of the Service Class to another Fund of the
Service Class. If you elect to reinvest the distributions paid by one Fund in
shares of another Fund of The Commerce Funds, the dividends or distributions
will be treated as received by you for tax purposes. Cross reinvestment
privileges do not apply to the Money Market Fund described under "Changing
Shares From Fund to Fund."

Redeeming Service Shares
--------------------------------------------------------------------------------

You May Sell Shares At Any Time: Your shares will be sold at the NAV next
calculated after The Commerce Funds' Transfer Agent receives your properly
completed order. Your order will be processed promptly and you will generally
receive the proceeds within a week. Please note: If the Fund has not yet
collected payment for the shares you are selling, it may delay sending the
proceeds for up to 15 business days.

Receipt Of Proceeds From A Sale: Ordinarily, sale proceeds will be disbursed
the next business day following receipt by the Transfer Agent of a properly
completed order. Payment by check will ordinarily be made within seven calendar
days following redemption or you may have your proceeds sent by federal wire to
your financial institution account. Proceeds will normally be wired the
business day after your request to redeem shares is received in good order by
the Transfer Agent. Your request to wire proceeds is subject to the financial
institution's wire charges.

Written requests to sell Service Shares must be signed by each shareholder,
including each joint owner. Certain types of redemption requests will need to
include a signature guarantee. You may obtain a signature guarantee from most
banks or securities dealers. Guarantees from notaries public will not be
accepted.

How Do I Redeem Shares From My Commerce Funds Account?

The following section describes how to redeem shares directly through The
Commerce Funds. The Commerce Funds has authorized certain dealers to redeem
shares of Funds on behalf of their clients. Some of the account features and
instructions described in this section may not be applicable to clients of
these dealers.

1. Consider Using An Automated Redemption:

. Making Automatic Withdrawals: If you are a shareholder with an account valued
at $5,000 or more, you may withdraw amounts in multiples of $100 or more from
your account on a monthly, quarterly, semi-annual or annual basis through the
Automatic Withdrawal feature. At your option, you may choose to have your
automatic withdrawal paid either by check or directly deposited into a
financial institution account. Withdrawals paid by check are distributed on
or about the 15th of the month. Direct deposits made to a financial
institution account can be made on any day of the month. To participate in
this feature, supply the necessary information on the account application or
in a subsequent written request. This feature may be suspended should the
value of your account fall below $500.

What Are The Important Things To Consider When Contacting The Commerce Funds By
Telephone?

You may call us at 1-800-995-6365 (8 a.m.- 5 p.m. CST) to explain what you want
to do. To make additions by phone or request electronic transfers or request
redemptions, we need your prior written authorization. If you did not check the
box in Section 8 of your original account application, you must send us a
letter that gives us this authorization.

Telephone purchases will be made at the NAV next determined after the Transfer
Agent receives payment for the transaction. If you should experience difficulty
in redeeming your shares by telephone (e.g., because of unusual market
activity), we urge you to consider redeeming your shares by mail.

You should note that the Transfer Agent may act on a telephone purchase or
redemption request from any person representing himself to be you and
reasonably believed by the Transfer Agent to be genuine. Neither The Commerce
Funds nor any of its service contractors will be liable for any loss or expense
in acting on telephone instructions that are reasonably believed to be genuine.
In attempting to confirm that telephone instructions are genuine, The Commerce
Funds will use all procedures considered reasonable; the Funds may be liable
for any losses if they fail to do so.

General Policies
--------------------------------------------------------------------------------

Dividend And Distribution Policies: As a Fund shareholder, you are entitled to
any dividends and distributions from net investment income and net realized
capital gains. You may choose one of the following distribution options for
dividends and capital gains:

(1) reinvest all dividend and capital gain distributions in additional
Service Shares,
(2) receive dividend distributions in cash and reinvest capital gain
distributions in additional Service Shares,

The Commerce Funds PAGE 27
---------------
.
<PAGE>

(3) receive all dividend and capital gain distributions in cash, or
(4) have all dividend and capital gain distributions deposited directly
into your designated account at a financial institution.

If you do not select an option when you open an account, all distributions will
automatically be reinvested in additional Service Shares of the same Fund. For
your protection, if you elect to have distributions mailed to you and these
cannot be delivered, they will be reinvested in additional Service Shares of
the same Fund. To change your distribution option, contact The Commerce Funds
at 1-800-995-6365 (8 a.m. - 5 p.m. CST). The change will become effective after
it is received in good order and processed by the Transfer Agent.

The Commerce Funds Reserve The Right To:
. Redeem your account involuntarily if, after 60 days' written notice, your
account's value remains below a $500 minimum balance. We will not redeem your
account involuntarily if the value falls below the minimum balance solely as
a result of market conditions. Retirement accounts and certain other accounts
will not be subject to automatic liquidation.

. Suspend or delay the payment of redemption proceeds when the NYSE is closed
(other than for customary weekend and holiday closings), during periods when
trading on the NYSE is restricted as determined by the SEC, during any
emergency as determined by the SEC or during other periods of unusual market
conditions.

. Without notice, stop offering shares of a Fund, reject any purchase order
(including exchanges), or bar an investor who is engaging in excessive
trading from purchasing or exchanging shares of a Fund.

Arrangements With Certain Institutions
Financial institutions or their designees that have entered into agreements
with The Commerce Funds or its agent may enter confirmed purchase orders on
behalf of clients and customers, with payment to follow no later than a Fund's
pricing on the following business day. If payment is not received by the Fund's
Transfer Agent by such time, the financial institution could be held liable for
resulting fees or losses. The Commerce Funds may be deemed to have received a
purchase or redemption order when a financial institution or its designee
accepts the order. Orders received by the Fund in proper form will be priced at
the Fund's POP next computed after they are accepted by the financial
institution or its designee. Financial institutions are responsible to their
customers and The Commerce Funds for timely transmission of all subscription
and redemption requests, investment information, documentation and money.

Business Of The Commerce Funds
--------------------------------------------------------------------------------

Shareholder Servicing
The Commerce Funds have adopted a distribution plan under Rule 12b-1 that
permits each Fund to pay up to 0.25% annually of their average daily net assets
attributable to the Service Shares. The Funds also have adopted a Shareholder
Administrative Services Plan that permits each Fund to pay up to 0.25% of
average daily net assets of Shares held under the plan to third parties for
providing shareholder services to the Shareholder Administrative Services Plan
participants. Because these fees are paid out of each Fund's assets, over time
they will increase the cost of your investment and may cost you more than
paying other types of sales charges.

Certain financial institutions may charge their customers account fees for
purchasing or redeeming shares of The Commerce Funds. These institutions may
provide shareholder services to their clients that are not available to a
shareholder dealing directly with The Commerce Funds. Each institution is
responsible for notifying its customers regarding its fees and additional or
changed purchase or redemption terms. You should contact your financial
institution for this information.

The Distributor and its affiliates may, out of its administration fee or other
resources, pay a fee of up to 0.25% of the amount invested or additional
incentives to dealers who initiate and are responsible for purchases of shares
of The Commerce Funds. In addition, at its expense, the Distributor will
provide additional compensation and promotional incentives to dealers in
connection with the sales of shares of the Funds. Subject to NASD regulation,
compensation may include promotional and other merchandise, sales and training
programs and other special events sponsored by dealers. Compensation may also
include payment for reasonable expenses incurred in connection with trips taken
by invited registered representatives for meetings or seminars of a business
nature.

The Commerce Funds will not issue share certificates. The Transfer Agent will

Tax Information
--------------------------------------------------------------------------------

The following is a brief summary of the federal income tax consequences of
investing in The Commerce Funds. You may also have to pay state and local taxes
on your investment, and you should always consult with your tax adviser for
specific guidance on your investment in The Commerce Funds.

Taxes on Distributions
The Funds' distributions will generally be taxable to shareholders as ordinary
income and capital gains (which may be taxable at different rates depending on
the length of time the Fund held the relevant assets). You will be subject to
income tax on these distributions regardless of whether they are paid in cash
or reinvested in additional shares. Once a year, The Commerce Funds will send
you a statement showing the types and total amount of distributions you
received during the previous year.

You should note that if you purchase shares just before a distribution, the
purchase price would reflect the amount of the upcoming distribution. In this
case, you would be taxed on the entire amount of the distribution received,
even though, as an economic matter, the distribution simply constitutes a
return of your capital. This is known as "buying into a dividend."

Taxes on Exchanges and Redemptions
When you redeem or exchange shares in any Fund, you may recognize a gain or
loss for income tax purposes. This gain or loss will be based on the difference
between your tax basis in the shares and the amount you receive for them. To
aid in computing your tax basis, you generally should retain your account
statements for the periods during which you held shares. Any loss realized on
shares held for six months or less will be treated as a long-term capital loss
to the extent of any capital gain dividends that were received with respect to
the shares. The one major exception to these tax rules is that distributions
on, and sales, exchanges and redemptions of, shares held in an IRA (or other
tax qualified plan) will not be currently taxable.

Backup Withholding
By law, The Commerce Funds must withhold 31% of your distributions and proceeds
if you have not provided complete, correct taxpayer information.

Tax Consequences of the National Tax-Free Intermediate Bond and Missouri Tax-
Free Intermediate Bond Funds (the "Tax-Free Intermediate Bond Funds")
The Tax-Free Intermediate Bond Funds' distributions will generally constitute
tax-exempt income for shareholders for federal income tax purposes. It is
possible, depending on the Funds' investments, that a portion of the Funds'
distributions could be taxable to shareholders as ordinary income or capital
gains, but the Funds do not expect that this will be the case. Moreover,
although distributions are exempt for federal income tax purposes, they will
generally constitute taxable income for state and local income tax purposes
except that, subject to limitations that vary depending on the state,
distributions from interest paid by a state or municipal entity may be exempt
from tax in that state.

Missouri Taxes: Resident individuals, trusts and estates resident in Missouri,
and corporations within Missouri tax jurisdiction will not be subject to
Missouri income tax

on dividends from the Missouri Tax-Free Intermediate Bond Fund that are derived
from interest on obligations of the State of Missouri and its political
subdivisions (to the extent such interest is exempt from federal income tax) or
on obligations issued by the U.S. Government, the Government of Puerto Rico,
the Virgin Islands or Guam. Resident individuals, trusts and estates and
corporations generally will be subject to Missouri income tax on other
dividends received from the Fund, including dividends derived from interest on
obligations of other issuers and all long-term and short-term capital gains.

OVERVIEW OF THE COMMERCE FUNDS

The Commerce Funds is an open-end, management investment company registered
under the Investment Company Act of 1940. The Commerce Funds is a Delaware
business trust, which was organized on February 7, 1994.

INVESTMENT OBJECTIVES, POLICIES AND RISK FACTORS

The following policies supplement the discussion of the National Tax-Free
Intermediate Bond and Missouri Tax-Free Intermediate Bond Funds' respective
investment objectives and policies as set forth in the Prospectuses. Investment
methods described in this Statement of Additional Information are among those
which one or more of the Funds have the power to utilize. Some may be employed
on a regular basis; others may not be used at all. Accordingly, reference to any
particular method or technique carries no implication that it will be utilized
or, if it is, that it will be successful.

National Tax-Free Intermediate Bond and Missouri Tax-Free Intermediate Bond
---------------------------------------------------------------------------
Funds
-----

The National Tax-Free Intermediate Bond Fund is a diversified series of The
Commerce Funds. The Missouri Tax-Free Intermediate Bond Fund is a
non-diversified series of the Funds. This means that it is permitted to invest
more than 5% of its assets in the obligations of a single issuer.

Each of the Funds may invest up to 10% of its total assets in unrated
obligations provided that such obligations are determined by the Advisor to be
comparable in quality to instruments that are eligible for purchase by the Fund.

Each of the Funds may invest up to 20% of its net assets in Municipal
Obligations the interest on which is exempt from regular federal income tax but
is an item of tax preference for purposes of the federal alternative minimum
tax. Each Fund may also invest up to 20% of its net assets for temporary
defensive purposes in short-term taxable money market instruments, in securities
issued by other investment companies which invest in taxable or tax-exempt money
market instruments and in U.S. Government Obligations, all as discussed below.

In addition, the Funds may hold uninvested cash reserves pending investment
during temporary defensive periods, or when, in the opinion of the Advisor,
suitable tax-exempt obligations are unavailable. There is no percentage
limitation on the amount of assets which may be held uninvested by the Funds.
Uninvested cash normally will not represent a significant portion of a Fund's
assets.

The Funds may invest from time to time in "money market instruments" a term
that includes, among other things, bank obligations, commercial paper and
corporate bonds with remaining maturities of 397 days or less.
<PAGE>

Futures Contracts and Related Options
-------------------------------------

The Funds may invest in futures contracts and options thereon (interest
rate futures contracts or index futures contracts, as applicable) for hedging
purposes or to seek to increase total return. Positions in futures contracts may
be closed out only on an exchange which provides a secondary market for such
futures. However, there can be no assurance that a liquid secondary market will
exist for any particular futures contract at any specific time. Thus, it may not
be possible to close a futures position. In the event of adverse price
movements, a Fund would continue to be required to make daily cash payments to
maintain its required margin. In such situations, if a Fund has insufficient
cash, it may have to sell portfolio securities to meet daily margin requirements
at a time when it may be disadvantageous to do so. In addition, a Fund may be
required to make delivery of the instruments underlying futures contracts it
holds. The inability to close options and futures positions also could have an
adverse impact on a Fund's ability to effectively hedge.

Successful use of futures by a Fund is also subject to the Advisor's
ability to correctly predict movements in the direction of the underlying
security or index. For example, if a Fund has hedged against the possibility of
a decline in the market adversely affecting securities held by it and securities
prices increase instead, the Fund will lose part or all of the benefit to the
increased value of its securities which it has hedged because it will have
approximately equal offsetting losses in its futures positions. In addition, in
some situations, if a Fund has insufficient cash, it may have to sell securities
to meet daily variation margin requirements. Such sales of securities may be,
but will not necessarily be, at increased prices which reflect the rising
market. A Fund may have to sell securities at a time when it may be
disadvantageous to do so.

The risk of loss in trading futures contracts in some strategies can be
substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing. As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor. For example, if at the time
of purchase, 10% of the value of the futures contract is deposited as margin, a
subsequent 10% decrease in the value of the futures contract would result in a
total loss of the margin deposit, before any deduction for the transaction
costs, if the account were then closed out. A 15% decrease would result in a
loss equal to 150% of the original margin deposit, before any deduction for the
transaction costs, if the contract were closed out. Thus, a purchase or sale of
a futures contract may result in losses in excess of the amount invested in the
contract.

Utilization of futures transactions by a Fund involves the risk of loss by
a Fund of margin deposits in the event of bankruptcy of a broker with whom the
Fund has an open position in a futures contract or related option.

Most futures exchanges limit the amount of fluctuation permitted in
futures contract prices during a single trading day. The daily limit establishes
the maximum amount that the price of a futures contract may vary either up or
down from the previous day's settlement price at the end of a trading session.
Once the daily limit has been reached in a particular type of contract, no
trades

-2-
<PAGE>

may be made on that day at a price beyond that limit. The daily limit governs
only price movement during a particular trading day and therefore does not limit
potential losses, because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of futures positions and subjecting some futures
traders to substantial losses.

The trading of futures contracts is also subject to the risk of trading
halts, suspensions, exchange or clearing-house equipment failures, government
intervention, insolvency of a brokerage firm or clearing house or other
disruptions of normal trading activity, which could at times make it difficult
or impossible to liquidate existing positions or to recover excess variation
margin payments.

A Fund may not purchase or sell futures contracts or options on futures
contracts to increase total return unless immediately after any such transaction
the aggregate amount of premiums paid for put options and the amount of margin
deposits on its existing futures positions do not exceed 5% of the total assets
of the Fund.

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

Each Fund may invest up to 15% of the value of its net assets in illiquid
securities, including securities having legal or contractual restrictions on
resale or no readily available market (including repurchase agreements, variable
and floating rate instruments and time deposits with notice/termination dates in
excess of seven days, stripped mortgage-backed securities ("SMBS") issued by
private issuers, interest rate and currency swaps and certain securities which
are subject to trading restrictions because they are not registered under the
Securities Act of 1933 (the "1933 Act")).

If otherwise consistent with its investment objective and policies, each
Fund may purchase commercial paper issued pursuant to Section 4(2) of the 1933
Act and securities that are not registered under the 1933 Act but can be sold to
"qualified institutional buyers" in accordance with Rule 144A under the 1933
Act. These securities will not be considered illiquid so long as the Advisor
determines, under guidelines approved by the Board of Trustees, that an adequate
trading market exists. A Fund's investment in Rule 144A securities could
increase the level of illiquidity during any period that qualified institutional
buyers becomes uninterested in purchasing these securities.

Interest Rate Swaps, Floors and Caps
------------------------------------

In order to hedge against fluctuations in interest rates, the Funds may
opt to enter into interest rate and mortgage swaps and interest rate caps and
floors. A Fund typically uses interest rate and mortgage swaps to preserve a
return on a particular investment or portion of its portfolio or to shorten the
effective duration of its portfolio securities. Interest rate swaps involve the
exchange by a Fund with another party of their respective commitments to pay or
receive interest, such as an exchange of fixed rate payments for floating rate
payments. Mortgage swaps are similar to interest rate swaps in that they
represent commitments to pay and receive interest.

-3-
<PAGE>

The notional principal amount, however, is tied to a reference pool or pools of
mortgages. The purchase of an interest rate floor or cap entitles the purchaser
to receive payments of interest on a notional principal amount from the seller,
to the extent that a specified index falls below (floor) or exceeds (cap) a
predetermined interest rate. In a typical cap or floor arrangement, one party
agrees to make payments only under specified circumstances, usually in return
for payment of a fee by the other party. For example, the buyer of an interest
rate cap obtains the right to receive payments to the extent that a specified
interest rate exceeds an agreed upon level, while the seller of an interest rate
floor is obligated to make payments to the extent that a specified interest rate
falls below an agreed upon level. Since interest rate swaps, mortgage swaps and
interest rate caps and floors are individually negotiated, a Fund expects to
achieve an acceptable degree of correlation between its portfolio investments
and its interest rate swaps, mortgage swaps and interest rate caps and floors
positions.

If a Fund enters into interest rate and mortgage swaps, it will do so only
on a net basis, i.e., the two payment streams are netted out, with the Fund
receiving or paying, as the case may be, only the net amount of the two
payments. Inasmuch as these transactions are entered into for good faith hedging
purposes, the Funds and the Advisor believe that such obligations do not
constitute senior securities as defined in the 1940 Act and, accordingly, do not
treat them as being subject to the Funds' borrowing restrictions. The net amount
of the excess, if any, of a Fund's obligations over its entitlements with
respect to each interest rate or mortgage swaps is accrued on a daily basis and
an amount of cash or liquid securities having an aggregate net asset value at
least equal to such accrued excess, is maintained in a segregated account by the
Fund's Custodian.

The use of interest rate swaps, mortgage swaps, caps and floors is a
highly specialized activity that involves investment techniques and risks
different from those associated with ordinary portfolio securities transactions.
If the Advisor is incorrect in its forecasts of market values and interest
rates, the investment performance of a Fund would be less favorable than it
would have been if these investment techniques were not used.

A Fund does not enter into any interest rate or mortgage swap or interest
cap or floor transaction unless the unsecured commercial paper, senior debt or
the claims-paying ability of the other party thereto is rated either AA or A-1
or Aa or P-1 or better by S&P or Moody's or the equivalent rating of another
NRSRO or if unrated by such rating organizations, determined by the Advisor to
be of comparable credit quality. If there is a default by the other party to
such a transaction, a Fund will have contractual remedies pursuant to the
agreements related to the transaction. The swap market has grown substantially
in recent years with a large number of banks and investment banking firms acting
both as principals and as agents utilizing standardized swap documentation. As a
result, the swap market has become relatively liquid in comparison with the
markets for other similar instruments which are traded in the relevant market.
However, the staff of the SEC takes the position that swaps, caps and floors are
illiquid for purposes of the Funds' limitations on investments in illiquid
securities.

-4-
<PAGE>

Lending Securities
------------------

Each Fund may lend its portfolio securities to broker/dealers and other
institutional investors pursuant to agreements requiring that the loans be
continuously secured by collateral equal in value at all times to at least the
market value of the securities loaned. Collateral for securities loans may
include cash, securities of the U.S. Government, its agencies or
instrumentalities, or an irrevocable letter of credit issued by a bank that
meets the investment standards defined as "money market instruments" below in
"Temporary Investments." When a Fund lends its securities, it continues to
receive interest or dividends on the securities loaned and may simultaneously
earn interest on the investment of the cash loan collateral which will be
invested in readily marketable, high-quality, short-term obligations. 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. Such loans will not be made if, as a result, the aggregate of all
outstanding loans exceeds 33 1/3% of the value of a Fund's total assets
(including the value of the collateral received for the loan). There may be
risks of delay in receiving additional collateral or in recovering the
securities loaned or even a loss of rights in the collateral should the borrower
of the securities fail financially. However, loans are made only to borrowers
deemed by the Advisor to be of good standing and when, in its judgment, the
income to be earned form the loan justifies the attendant risks.

Municipal Obligations
---------------------

The Funds may invest in Municipal Obligations. Municipal Obligations
include debt obligations issued by governmental entities to obtain funds for
various public purposes, including the construction of a wide range of public
facilities, the refunding of outstanding obligations, the payment of general
operating expenses and the extension of loans to public institutions and
facilities.

The two principal classifications of Municipal Obligations consist of
"general obligation" and "revenue" issues, and the respective portfolios may
also purchase "moral obligation" issues, which are normally issued by special
purpose authorities. General obligation securities are secured by the issuer's
pledge of its full faith, credit and taxing power for the payment of principal
and interest. Revenue securities are payable only from the revenues derived from
a particular facility or class of facilities or, in some cases, from the
proceeds of a special excise tax or other specific revenue source such as the
user of the facility being financed. Private activity bonds (e.g., bonds issued
by industrial development authorities) that are issued by or on behalf of public
authorities to finance various privately-operated facilities are included within
the term "Municipal Obligations" if the interest paid thereon is exempt from
regular federal income tax and not treated as a specific tax preference item
under the federal alternative minimum tax. Private activity bonds are in most
cases revenue securities and are not payable from the unrestricted revenues of
the issuer. The credit quality of such bonds is usually directly related to the
credit standing of the corporate user of the facility involved. If the issuer of
moral obligation securities is unable to meet its debt service obligations from
current revenues, it may draw on a reserve fund, the restoration of which is a
moral commitment but not a legal obligation of the state or municipality which
created the issuer.

-5-
<PAGE>

There are, of course, variations in the quality of Municipal Obligations both
within a particular classification and between classifications, and the yields
on Municipal Obligations depend upon a variety of factors, including general
money market conditions, the financial condition of the issuer, general
conditions of the municipal bond market, the size of a particular offering, the
maturity of the obligation and the rating of the issue.

Although the Funds will invest most of their assets, under normal
circumstances, in intermediate-term Municipal Obligations, the Funds may also
purchase short-term project notes, tax anticipation notes, bond anticipation
notes, revenue anticipation notes, tax-exempt commercial paper, and other forms
of short-term tax-exempt loans. Such instruments are issued with a short-term
maturity in anticipation of the receipt of tax funds, the proceeds of bond
placements or other revenues.

Further, the Funds may purchase Municipal Obligations known as
"certificates of participation" which represent undivided proportional interests
in lease payments by a governmental or non-profit entity. The lease payments and
other rights under the lease provide for and secure the payments on the
certificates. Lease obligations may be limited by applicable municipal charter
provisions or the nature of the appropriation for the lease. In particular,
lease obligations may be subject to periodic appropriation. If the entity does
not appropriate funds for future lease payments, the entity cannot be compelled
to make such payments. Furthermore, a lease may or may not provide that the
certificate trustee can accelerate lease obligations upon default. If the
trustee could not accelerate lease obligations upon default, the trustee would
only be able to enforce lease payments as they became due. In the event of a
default or failure of appropriation, it is unlikely that the trustee would be
able to obtain an acceptable le substitute source of payment. Certificates of
participation are generally subject to redemption by the issuing municipal
entity under specified circumstances. If a specified event occurs, a certificate
is callable at par either at any interest payment date or, in some cases, at any
time. As a result, certificates of participation are not as liquid or marketable
as other types of Municipal Obligations.

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 the 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. The
Commerce Funds cannot predict what legislation, if any, may be proposed or
enacted in the future regarding the federal tax status of interest on such
obligations or, with respect to the Missouri Tax-Free Intermediate Bond Fund,
what legislation may be proposed in the Missouri Legislature relating to the
status of the Missouri income tax on interest on Missouri obligations. Such
proposals, whether pending or enacted, might materially and adversely affect the
availability of Municipal or Missouri Obligations for investment by a particular
Fund and the liquidity and value of its respective 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 a Fund may be insured as to
the timely payment of principal and interest. The insurance policies will
usually be obtained by the issuer of

-6-
<PAGE>

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 will not protect against market fluctuations caused by changes in
interest rates and other factors. The Funds may, from time to time, invest more
than 25% of their assets in Municipal Obligations covered by insurance policies.

Options Trading
---------------

Each of the Funds may purchase put and call options and may write covered
call and secured put options, which will be listed on a national securities
exchange and issued by the Options Clearing Corporation. The aggregate value of
securities subject to options written by the Funds will not exceed 5% of the
respective Fund's total assets. Notwithstanding the foregoing, a Fund may not
purchase or sell futures contracts or options on futures contracts to increase
total return unless immediately after any such transaction, the aggregate amount
of premiums paid for put options and the amount of margin deposits on existing
futures positions do not exceed 5% of the total assets of the Fund.

Options may relate to particular securities and various stock indexes or
currencies. This is a highly specialized activity which entails greater than
ordinary investment risks. Regardless of how much the market price of the
underlying security increases or decreases, the option buyer's risk is limited
to the amount of the original investment for the purchase of the option.
However, options may be more volatile than the underlying securities, and
therefore, on a percentage basis, an investment in options may be subject to
greater fluctuation than an investment in the underlying securities themselves.
A listed call option gives the purchaser of the option the right to buy from a
clearing corporation, and a writer has the obligation to sell to the clearing
corporation, 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
obligations under the option contract. A listed put option gives the purchaser
the right to sell to a clearing corporation the underlying 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. Put and call options purchased
by a Fund will be valued at the last sale price or, in the absence of such a
price, at the mean between bid and asked prices.

The Funds will write only "covered" call options on securities. The option
is "covered" if a Fund owns the security underlying the call or has an absolute
and immediate right to acquire that security without additional cash
consideration (or, if additional cash consideration is required, cash or cash
equivalents in such amount as are held in a segregated account by its Custodian)
upon conversion or exchange of other securities held by it. A call option is
also covered if a Fund holds a call on the same security as the call written
where the exercise price of the call held is (i) equal to or less than the
exercise price of the call written, or (ii) greater than the exercise price of
the call written provided the difference is maintained by the Fund in cash or
cash equivalents in a segregated account with its Custodian.

-7-
<PAGE>

A Fund's obligation to sell a security subject to a covered call option
written by it, or to purchase a security subject to a secured put option written
by it, may be terminated prior to the expiration date of the option by the
Fund's executing a closing purchase transaction, which is effected by purchasing
on an exchange an option of the same series (i.e., the same underlying security,
exercise price and expiration date) as the option previously written. Such a
purchase does not result in the ownership of an option. A closing purchase
transaction will ordinarily be effected to realize a profit on an outstanding
option, to prevent an underlying security from being called, to permit the sale
of the underlying security or to permit the writing of a new option containing
different terms on such underlying security. The cost of such a liquidation
purchase plus transaction costs may be greater than the premium received upon
the original option, in which event the Fund will have incurred a loss in the
transaction. An option position may be closed out only on an exchange which
provides a secondary market for an option of the same series. There is no
assurance that a liquid secondary market on an exchange will exist for any
particular option. A covered call option writer, unable to effect a closing
purchase transaction, will not be able to sell the underlying security until the
option expires or the underlying security is delivered upon exercise with the
result that the writer in such circumstances will be subject to the risk of
market decline in the underlying security during such period. A Fund will write
an option on a particular security only if the Advisor believes that a liquid
secondary market will exist on an exchange for options of the same series which
will permit the Fund to make a closing purchase transaction in order to close
out its position.

When a Fund purchases a put or call option, the premium paid by it is
recorded as an asset of the Fund. When a Fund writes an option, an amount equal
to the net premium (the premium less the commission) received by the Fund is
included in the liability section of the Fund's statement of assets and
liabilities as a deferred credit. The amount of this asset or deferred credit
will be subsequently marked-to-market to reflect the current value of the option
purchased or written. The current value of the traded option is the last sale
price or, in the absence of a sale, the average of the closing bid and asked
prices. If an option purchased by a Fund expires unexercised, the Fund realizes
a loss equal to the premium paid. If a Fund enters into a closing sale
transaction on an option purchased by it, the Fund will realize a gain if the
premium received by the Fund on the closing transaction is more than the premium
paid to purchase the option, or a loss if it is less. If an option written by a
Fund expires on the stipulated expiration date or if a Fund enters into a
closing purchase transaction, it will realize a gain (or loss if the cost of a
closing purchase transaction exceeds the net premium received when the option is
sold) and the deferred credit related to such option will be eliminated. If an
option written by a Fund is exercised, the proceeds of the sale will be
increased by the net premium originally received and the Fund will realize a
gain or loss.

As noted previously, there are risks associated with transactions in
options on securities. For example, there are significant differences between
the securities and options markets that could result in an imperfect correlation
between these markets, causing a given transaction not to achieve its
objectives. In addition, a liquid secondary market for particular options,
whether traded over-the-counter or on a national securities exchange
("Exchange"), may be absent for reasons which include the following: there may
be insufficient trading interest in certain options; restrictions may be imposed
by an Exchange on opening transactions or closing transactions or

-8-
<PAGE>

both; trading halts, suspensions or other restrictions may be imposed with
respect to particular classes or series of options or underlying securities;
unusual or unforeseen circumstances may interrupt normal operations on an
Exchange; the facilities of an Exchange or the Options Clearing Corporation may
not at all times be adequate to handle current trading volume; or one or more
Exchanges could, for economic or other reasons, decide or be compelled at some
future date to discontinue the trading of options (or a particular class or
series of options), in which event the secondary market on that Exchange (or in
that class or series of options) would cease to exist, although outstanding
options that had been issued by the Options Clearing Corporation as a result of
trades on that Exchange would continue to be exercisable in accordance with
their terms. A Fund will likely be unable to control losses by closing its
position where a liquid secondary market does not exist. A decision as to
whether, when and how to use options involves the exercise of skill and
judgment, and even a well-conceived transaction may be unsuccessful to some
degree because of market behavior or unexpected events. Successful use of
options by a Fund is subject to the Advisor's ability to correctly predict
movements in the direction of stock prices, interest rates and other economic
factors.

Portfolio Turnover
------------------

The annualized portfolio turnover rate for each Fund is calculated by
dividing the lesser of purchases or sales of portfolio securities for the year
by the monthly average market value of the portfolio securities. The calculation
excludes all securities, including options, whose maturities or expiration dates
at the time of acquisition are one year or less. Fund turnover may vary greatly
from year to year as well as within a particular year, and may be affected by
cash requirements for redemption of shares and by requirements which enable the
Fund to receive favorable tax treatment. Fund turnover will not be a limiting
factor in making portfolio decisions, and each Fund may engage in short-term
trading to achieve its investment objective.

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

Investment-grade obligations are those rated at the time of purchase AAA,
AA, A or BBB by S&P, Aaa, Aa, A or Baa by Moody's or which are similarly rated
by another nationally recognized statistical rating organization ("NRSRO")
(including Fitch and Thomson BankWatch) or are unrated but deemed by the Advisor
to be comparable in quality to instruments that are so rated. Obligations rated
BBB by S&P, Baa by Moody's or the equivalent rating of another NRSRO are
considered to have speculative characteristics and are subject to greater credit
and market risk than securities rated in the top three investment-grade
categories.

Subsequent to their purchase by the Funds, a Fund's portfolio securities
may be downgraded below investment grade or may be deemed by the Advisor to be
no longer comparable to investment-grade securities. The Advisor will consider
such an event in determining whether the Fund should continue to hold the
security. See Appendix A for a description of applicable debt ratings.

The ratings of Moody's, S&P, Fitch and Thomson BankWatch, as NRSROs,
represent their opinions as to the quality of debt securities. It should be
emphasized, however, that

-9-
<PAGE>

ratings are general and are 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 its 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 conjunction with the particular Fund's investment
policy when determining whether the Fund should continue to hold the obligation.

The payment of principal and interest on most securities purchased by the
Funds will depend upon the ability of the issuers to meet their obligations. An
issuer's obligations under its debt securities are subject to the provisions of
bankruptcy, insolvency, and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Code, and laws, if any, which may be
enacted by federal or state legislatures extending the time for payment of
principal or interest, or both, or imposing other constraints upon enforcement
of such obligations or, in the case of governmental entities, upon the ability
of such entities to levy taxes. The power or ability of an issuer to meet its
obligations for the payment of interest on and principal of its debt securities
may be materially adversely affected by litigation or other conditions.

Attached to this Statement of Additional Information is Appendix A, which
contains descriptions of the rating symbols used by NRSROs for securities in
which the Funds may invest.

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

Each Fund may enter into repurchase agreements under which it buys a
security and obtains a simultaneous commitment from the seller to repurchase the
security at a specified time and price. The seller must maintain with a Fund's
Custodian collateral equal to at least 100% of the repurchase price including
accrued interest as monitored daily by the Advisor. If the seller under the
repurchase agreement defaults, a Fund may incur a loss if the value of the
collateral securing the repurchase agreement has declined and may incur
disposition costs in connection with liquidating the collateral. If bankruptcy
proceedings are commenced with respect to the seller, liquidation of the
collateral by a Fund may be delayed or limited.

The repurchase price under the repurchase agreements described in the
Funds' Prospectuses generally equals the price paid by a Fund plus interest
negotiated on the basis of current short-term rates (which may be more or less
than the rate on the securities underlying the repurchase agreement). Securities
subject to repurchase agreements are held by the Funds' Custodian (or
sub-Custodian) or in the Federal Reserve/Treasury book-entry system. Repurchase
agreements are considered to be loans under the 1940 Act.

Reverse Repurchase Agreements
-----------------------------

Each Fund may borrow money for temporary purposes by entering into
transactions called reverse repurchase agreements. Under these agreements, a
Fund sells portfolio securities to a financial institution (such as a bank or
broker-dealer) and agrees to buy them back later at an agreed upon time and
price. When a Fund enters into a reverse repurchase agreement, it places in a

-10-
<PAGE>

separate custodial account cash or liquid assets that have a value equal to or
greater than the repurchase price. The account is then continuously monitored by
the Advisor to make sure that an appropriate value is maintained. Reverse
repurchase agreements involve the risk that the value of portfolio securities a
Fund relinquishes may decline below the price the Fund must pay on the
repurchase date. A Fund will only enter into reverse repurchase agreements to
avoid the need to sell its securities to meet redemption requests during
unfavorable market conditions. As reverse repurchase agreements are deemed to be
borrowings by the SEC, each Fund is required to maintain continuous asset
coverage of 300%. Should the value of a Fund's assets decline below 300% of
borrowings, a Fund may be required to sell portfolio securities within three
days to reduce the Fund's debt and restore 300% asset coverage.

Securities Issued by Other Investment Companies
-----------------------------------------------

Each Fund may invest in securities issued by other investment companies
within the limits prescribed by the 1940 Act. Each Fund currently intends to
limit its investments so that, as determined immediately after a purchase is
made: (a) not more than 5% of the value of its total assets will be invested in
the securities of any one investment company; (b) not more than 10% of the value
of its total assets will be invested in the aggregate in securities of
investment companies as a group; (c) not more than 3% of the outstanding voting
stock of any one investment company will be owned by the Fund; and (d) not more
than 10% of the outstanding voting stock of any one investment company will be
owned in the aggregate by the Fund and other investment companies advised by the
Advisor, or any affiliate of Commerce Bancshares, Inc. As a shareowner of
another investment company, a Fund would bear, along with other shareowners, its
pro rata portion of the expenses of such other investment company, including
advisory fees. These expenses would be in addition to the advisory and other
expenses that a Fund bears directly in connection with its own operations and
may represent a duplication of fees to shareowners of the Fund.

Special Considerations Regarding Investment in Missouri Obligations
-------------------------------------------------------------------

The following discussion highlights some of the more important economic
and financial trends and considerations affecting Missouri Obligations and is
based on information from official statements, prospectuses and other publicly
available documents relating to, among other things, securities offerings of the
State of Missouri, its agencies and instrumentalities, as available on the date
of this Statement of Additional Information. The Commerce Funds has not
independently verified any of the information contained in such statements or
other documents.

Missouri's population was 5,468,338 on July 1, 1999 according to the
Population Estimates Program, Population Division, U.S. Bureau of the Census,
which represented an increase of 6.8% from the 1990 decennial census of
5,117,073 inhabitants. As of July, 1998, St. Louis and the surrounding
metropolitan area constituted the 18th largest Metropolitan Statistical Area
(MSA) in the nation with approximately 2.56 million inhabitants, more than half
of which were Missouri residents. St. Louis is located on the eastern boundary
of the State on the Mississippi River and is a distribution center and an
important site for banking and manufacturing activity. Anchoring the western
boundary is Kansas City, which is Missouri's second largest metropolitan area.
In 1998, Kansas City was the 24th largest MSA nationally with

-11-
<PAGE>

approximately 1.73 million inhabitants, more than half of which were Missouri
residents. Kansas City is a major agri-business center for the United States and
is an important center for finance and industry. Springfield, St. Joseph, Joplin
and Columbia are also important population and industrial centers in the State.
Missouri's personal income rose by 4.4% during calendar year 1999, as compared
to the national average of an estimated 5.4%. Missouri's employment stood at
2,830,400 at the end of October 1999, up 1,320 from June of 1998. At the end of
November 1999, the state unemployment rate was at a historic low of 2.3%
compared to 4.3% (as revised) at the end of June 1998. The national rate was
3.8% at the end of November 1999.

The major sectors of the State's economy include agriculture,
manufacturing, trade, government and services. Farming has traditionally played
a dominant role in the economy and yielded a large portion of the State's
revenues. Although the concentration in farming remains above the national
average, with increasing urbanization, significant income-generating activity
has shifted from agriculture to manufacturing and services. Earnings and
employment are distributed among the manufacturing, trade and service sectors in
a close approximation of the average national distribution, thus lessening the
State's cyclical sensitivity to impact by any single sector. In 1999, services
represented the single most significant non-agriculture economic activity, with
wholesale and retail trade ranking second and manufacturing ranking third. In
1996, these three economic sectors accounted for 67.6% of the State's
nonagricultural employment. Manufacturing, which accounts for approximately
14.9% of employment, is concentrated in industrial machinery, transportation
equipment and other durable goods. To the extent that the economy suffers a
recession, the manufacturing sector, in particular, could be adversely affected.

Defense-related businesses play an important role in Missouri's economy.
In addition to the large number of civilians employed at the various military
installations and training bases in the State, aircraft production and
defense-related businesses receive sizeable annual defense contract awards. In
1998, Missouri ranked sixth among the states in Department of Defense contract
awards compared to a ranking of fourth in 1996. The continued decline in defense
appropriations by the U.S. Congress have had and will continue to have an impact
on the State.

Limitations on State debt and bond issues are contained in Article III,
Section 37 of the Constitution of Missouri. Pursuant to this section, (1) the
General Assembly may issue general obligation bonds solely to refund outstanding
bonds (provided that the refunding bonds must mature within 25 years of
issuance); (2) the General Assembly upon the recommendation of the Governor to
incur a temporary liability by reason of unforeseen emergency or of deficiency
in revenue, may issue bonds in an amount not to exceed $1 million for any one
year (must be paid within 5 years of issuance); and (3) the General Assembly, or
the people by initiative, may submit a proposition to incur temporary
indebtedness greater than $1 million by reason of unforeseen emergency or of
deficiency in revenue, and the bonds may be issued if approved by a majority of
those voting (such bonds must be retired serially and by installment within 25
years of issuance). Before any bonds are issued pursuant to Section 37, the
General Assembly must make provisions for the payment of principal and interest
and may provide for an annual tax on all taxable property in an amount
sufficient for that purpose.

-12-
<PAGE>

Certain water pollution bonds and State building bonds are also authorized
pursuant to Section 37(b)-(h), inclusive. In 1971, Missouri voters approved a
constitutional amendment providing for the issuance of $150 million of general
obligation bonds for the protection of the environment through the control of
water pollution. In 1979, voters approved a constitutional amendment authorizing
an additional $200 million of State Water Pollution Control Bonds. In 1982,
State voters approved a constitutional amendment authorizing the issuance of
$600 million of Third State Building Bonds. Proceeds from the Third State
Building Bonds are used to provide funds for improvement of State buildings and
property, including education, mental health, parks, corrections and other State
facilities, and for water, sewer, transportation, soil conservation and other
economic development projects. In 1988, and as amended in 1998, Missouri voters
approved a constitutional amendment authorizing the issuance of bonds in the
aggregate sum of $275 million for controlling water pollution and making
improvements to drinking water systems. In 1994, state voters approved a
constitutional amendment authorizing the issuance of $250 million Fourth State
Building Bonds. Proceeds from the Fourth State Building Bonds fund the
rebuilding of institutions of higher education, land acquisition, construction
and purchase of buildings, and planning, furnishing, equipping and landscaping
such improvements and buildings. In 1998, voters approved a constitutional
amendment authorizing the issuance of bonds in the aggregate sum of $100 million
for the purpose of providing rural water and sewer grants and loans, including
grants for the establishment of water supply hook-ups in unincorporated areas of
any county to water supplies. In 1998, voters approved a constitutional
amendment authorizing the issuance of bonds in the aggregate amount of $200
million for the purpose of providing funds for providing stormwater control
plans, studies and projects in certain counties and cities.

Article III, Section 36 of the Constitution of Missouri requires that the
General Assembly appropriate the annual principal and interest requirements for
outstanding general obligation bonds before any other appropriations are made.
Such amounts must be transferred from the General Revenue Fund to bond interest
and sinking funds. Authorization for these transfers, as well as the actual
payments of principal and interest, are provided in the first appropriation bill
of each fiscal year.

In addition to general obligation bonds, the Missouri legislature has
established numerous entities as bodies corporate and politic, which are
authorized to issue bonds to carry out their corporate purposes.

Article X, Section 16-24 of the Constitution of Missouri (the "Tax
Limitation Amendment") imposes a limit on the amount of taxes and other revenue
enhancement charges such as user fees which may be imposed by the State or a
political subdivision in any fiscal year. This limit is tied to total State
revenues for the fiscal year ended June 30, 1981, as defined in the Tax
Limitation Amendment, and adjusted annually, in accordance with the formula set
forth in the amendment. Under that formula, the revenue limit (the "Revenue
Limit") for any fixed year equals the product obtained by multiplying (i) the
ratio of total state revenues in fiscal year 1980-1981 divided by the aggregate
personal income received by persons in Missouri from all sources ("Personal
Income of Missouri") in calendar year 1979 times (ii) the Personal Income of

-13-
<PAGE>

Missouri in either the calendar year prior to the calendar year in which
appropriations for the fiscal year for which the calculation is being made, or
the average of Personal Income of Missouri in the previous three calendar years,
whichever is greater. If the Revenue Limit is exceeded by 1% or more in any
fiscal year, a refund of the excess revenues collected by the State is required.
If the excess revenues collected are less than 1%, then the excess is not
refunded but is transferred to the General Revenue Fund. The details of the Tax
Limitation Amendment are complex and clarification from subsequent legislation
and judicial decisions may be necessary for the Tax Limitation Amendment to be
fully implemented. The Revenue Limit can be exceeded only if the General
Assembly approves by a two-thirds vote of each house an emergency declaration as
requested by the Governor. The Revenue Limit does not apply to taxes imposed for
payment of principal and interest on bonds that have been approved by the
voters, as authorized by the Missouri Constitution. In 1999, total state
revenues exceeded the total state revenue limit by $98.9 million, the entire
amount of which will be refunded to Missouri taxpayers in calendar year 2000.
The Missouri office of Administration projects that in fiscal year 2000 and
2001, total state revenues will not exceed the total state revenue limit.

In addition, to the Revenue Limit, the General Assembly is prohibited
without voter approval from increasing taxes as fees in any fiscal year that in
total produces new annual revenues greater than $50 million, adjusted annually
by the percentage change in the personal income of Missouri for the second
previous fiscal year, or 1% of total state revenue for the previous fiscal year
prior to the General Assembly action, whichever is less. The Tax Limitation
Amendment could adversely affect the repayment capabilities of certain
non-general obligation issues if payment is dependent upon increases in taxes or
appropriations by the State's General Assembly.

General revenue collections in fiscal year 1999 were $7,078 million, 6.45%
above fiscal year 1998 collections. The fiscal year 2000 budget is
conservatively based upon general revenue collections of $7,016 million.

Stand-By Commitments
--------------------

The Funds may acquire stand-by commitments with respect to Municipal
Obligations held within their respective portfolios. Under a stand-by
commitment, a dealer or bank agrees to purchase from a Fund, at the Fund's
option, specified Municipal Obligations at their amortized cost value to the
Fund plus accrued interest, if any. Stand-by commitments may be sold,
transferred or assigned by a Fund only with the underlying instrument.

The Funds expect that stand-by commitments will generally be available
without the payment of any direct or indirect consideration. However, if
necessary or advisable, a Fund may pay for a stand-by commitment either
separately in cash or by paying a higher price for portfolio securities which
are acquired subject to the commitment (thus reducing the yield to maturity
otherwise available for the same securities). Where a Fund paid any
consideration directly or indirectly for a stand-by commitment, its cost would
be reflected as unrealized depreciation for the period during which the
commitment was held by the Fund.

-14-
<PAGE>

The Funds intend to enter into stand-by commitments only with dealers,
banks and broker-dealers which, in the Advisor's opinion, present minimal credit
risks. The Funds' reliance upon the credit of these dealers, banks and
broker-dealers will be secured by the value of the underlying Municipal
Obligations that are subject to the commitment. In evaluating the
creditworthiness of the issuer of a stand-by commitment, the Advisor will review
periodically the issuer's assets, liabilities, contingent claims and other
relevant financial information.

The Funds would acquire stand-by commitments solely to facilitate
portfolio liquidity and do not intend to exercise their rights thereunder for
trading purposes. Stand-by commitments acquired by a Fund would be valued at
zero in determining net asset value.

Temporary Investments
---------------------

Each Fund may assume a temporary defensive position at times when the
Advisor believes such a position is warranted by uncertain or unusual market
conditions. Such a position would allow a Fund to deviate from its fundamental
and non-fundamental policies. Each Fund may invest for temporary defensive
purposes up to 100% of its total assets in cash or cash equivalent short-term
obligations including "money market instruments," a term which includes, among
other things, bank obligations, commercial paper and notes, U.S. Government
Obligations, foreign government securities (if permitted), repurchase agreements
and corporate bonds with remaining maturities of 397 days or less.

Bank obligations include bankers' acceptances, negotiable certificates of
deposit and non-negotiable time deposits, including U.S. dollar-denominated
instruments issued or supported by the credit of U.S. or foreign banks or
savings institutions. Bank obligations also include obligations of foreign banks
or foreign branches of U.S. banks. Although the Funds will invest in obligations
of foreign banks or foreign branches of U.S. banks only where the Advisor deems
the investment to present minimal credit risks, such investments nevertheless
entail risks that are different from those of investments in domestic
obligations of U.S. banks due to differences in political, regulatory and
economic systems and conditions. These risks may include future unfavorable
political and economic developments, possible withholding taxes on interest
income, seizure or nationalization of foreign deposits, currency controls,
interest limitations, or other governmental restrictions which might affect the
payment of principal or interest on the securities held by the Fund.
Additionally, these institutions may be subject to less stringent reserve
requirements and to different accounting, auditing, reporting and recordkeeping
requirements than those applicable to domestic branches of U.S. banks. All
investments in bank obligations are limited to the obligations of financial
institutions having more than $1 billion in total assets at the time of
purchase.

Certificates of deposit issued by domestic branches of domestic banks do
not benefit materially, and certificates of deposit issued by foreign branches
of domestic banks do not benefit at all, from insurance from the Federal Deposit
Insurance Corporation.

Both domestic banks and foreign branches of domestic banks are subject to
extensive governmental regulations which may limit both the amount and types of
loans which may

-15-
<PAGE>

be made and interest rates which may be charged. In addition, the profitability
of the banking industry is dependent largely upon the availability and costs of
funds for the purpose of financing and lending operations under prevailing money
market conditions. General economic conditions as well as exposure to credit
losses arising from possible financial difficulties of borrowers play an
important part in the operations of this industry.

Investments by the Funds in taxable commercial paper will consist of
issues that are rated A-1 or better by S&P, Prime-1 by Moody's or the equivalent
rating of another rating agency. Commercial paper may include variable and
floating rate instruments.

When the Advisor pursues a temporary defensive strategy, the Funds may not
profit from favorable developments that would have been available if the Funds
were pursuing their normal investment strategies. In addition, when the Advisor
uses a defensive strategy, the Funds will not be pursuing their investment
objectives.

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

As stated in the Prospectuses, pursuant to their respective investment
objectives, the Funds may invest in U.S. Government Obligations. Examples of the
types of U.S. Government Obligations which may be held by the Funds include, in
addition to U.S. Treasury bonds, notes and bills, the obligations of Federal
Home Loan Banks, Federal Farm Credit Banks, Federal Land Banks, the Federal
Housing Administration, Farmers Home Administration, Export-Import Bank of the
United States, Small Business Administration, Government National Mortgage
Association, Federal National Mortgage Association, General Services
Administration, Student Loan Marketing Association, Central Bank for
Cooperatives, Federal Home Loan Mortgage Corporation, Federal Intermediate
Credit Banks and Maritime Administration. Obligations of certain agencies and
instrumentalities of the U.S. Government, such as those of the Government
National Mortgage Association, are supported by the right of the issuer to
borrow from the Treasury; others, such as those of the Federal National Mortgage
Association, are supported by the discretionary authority of the U.S. Government
to purchase the agency's obligations; still others, such as those of the Student
Loan Marketing Association, are supported only by the credit of the
instrumentality. No assurance can be given that the U.S. Government would
provide financial support to U.S. Government-sponsored instrumentalities if it
is not obligated to do so by law.

U.S. Government Obligations purchased by the Short-Term Government Fund
with nominal remaining maturities in excess of five years that have variable or
floating interest rates or demand or put features may nonetheless be deemed to
have remaining maturities of five years or less so as to be permissible
investments as follows: (a) a government security with a variable or floating
rate of interest will be deemed to have a maturity equal to the period remaining
until the next readjustment of the interest rate; (b) a government security with
a demand or put feature that entitles the holder to receive the principal amount
of the underlying security at the time of or sometime after the holder gives
notice of demand or exercise of the put will be deemed to have a maturity equal
to the period remaining until the principal amount can be recovered through
demand or exercise of the put; and (c) a government security with both a
variable or floating rate of interest as described in clause (a) and a demand or
put feature as described in clause (b) will be deemed to

-16-
<PAGE>

have a maturity equal to the shorter 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 or exercise of the put.

U.S. Government Obligations have historically involved little risk of loss
of principal if held to maturity. The Short-Term Government Fund, however, will
not necessarily hold its securities to maturity. Generally, the market value of
securities not held to maturity can be expected to vary universally to changes
in prevailing interest rates. In addition, neither the U.S. Government, nor any
agency or instrumentality thereof has guaranteed, sponsored or approved the
Short-Term Government Fund or its shares. No assurance can be given that the
U.S. Government would provide financial support to U.S. Government-sponsored
instrumentalities if it is not obligated to do so by law.

Variable and Floating Rate Instruments
--------------------------------------

The Funds may purchase variable rate and floating rate obligations issued
by corporations, industrial development authorities and governmental entities.
Such instruments are frequently not rated by credit rating agencies. However, in
determining the creditworthiness of unrated variable and floating rate
instruments and their eligibility for purchase by the Funds, the Advisor will
consider the earning power, cash flows and other liquidity ratios of the issuers
and guarantors of such obligations and, if the obligation is subject to a demand
feature, will monitor their financial status to meet payment on demand. In
determining average weighted portfolio maturity, an instrument will usually be
deemed to have a maturity equal to the longer of the period remaining to the
next interest rate adjustment or the time a Fund can recover payment of
principal as specified in the instrument.

While there may be no active secondary market with respect to a particular
variable or floating rate instrument purchased by a Fund, a Fund may, from time
to time as specified in the instrument, demand payment in full of the principal
of the instrument or may resell the instrument to a third party. The absence of
such an active secondary market, however, could make it difficult for a Fund to
dispose of a variable or floating rate demand instrument if the issuer defaulted
on its payment obligations during periods that a Fund is not entitled to
exercise its demand rights, and a Fund could, for these or other reasons, suffer
a loss. Variable and floating rate instruments with no active secondary market
and with notice/termination dates in excess of seven days will be included in
the calculation of a Fund's illiquid assets.

Variable and floating rate demand instruments acquired by the Funds may
include participations in Municipal Obligations purchased from and owned by
financial institutions (primarily banks). Participation interests provide the
Fund with a specified undivided interest (up to 100%) in the underlying
obligation and the right to demand payment of the unpaid principal balance plus
accrued interest on the participation interest from the institution upon a
specified number of days' notice, not to exceed thirty days. Each participation
interest is backed by an irrevocable letter of credit or guarantee of a bank
that the Advisor has determined meets the prescribed quality standards for the
Fund. The bank typically retains fees out of the interest paid on

-17-
<PAGE>

the obligation for servicing the obligation, providing the letter of credit and
issuing the repurchase commitment.

When-Issued Purchases and Forward Commitments
---------------------------------------------

Each Fund may purchase securities on a when-issued basis or enter into
forward commitment transactions. These transactions, which involve a commitment
by a Fund to purchase or sell particular securities with payment and delivery
taking place at a future date (perhaps one or two months later), permit the Fund
to lock in a price or yield on a security it owns or intends to purchase,
regardless of future changes in market prices or in interest rates. When-issued
and forward commitment transactions involve the risk, however, that the yield or
price obtained in a transaction (and therefore the value of the security) may be
less favorable than the yield or price (and therefore the value of the security)
available in the market when the securities delivery takes place. When a Fund
agrees to purchase securities on a when-issued basis or enters into a forward
commitment to purchase securities, the Funds' Custodian will set aside cash or
liquid assets, as permitted by applicable law, equal to the amount of the
purchase or the commitment in a separate account. Normally, the Custodian will
set aside portfolio securities to meet this requirement. The market value of the
separate account will be monitored and if such market value declines, the Fund
will be required subsequently to place additional assets in the separate account
in order to ensure that the value of the account remains equal to the amount of
the Fund's commitments. Because a Fund will set aside cash or liquid assets, as
permitted by applicable law, in the manner described, the Fund's liquidity and
ability to manage its portfolio might be affected in the event its when-issued
purchases or forward commitments ever exceeded 25% of the value of its assets.
In the case of a forward commitment to sell portfolio securities, the Custodian
will hold the portfolio securities in a segregated account while the commitment
is outstanding.

A Fund will make commitments to purchase securities on a when-issued basis
or to purchase or sell securities on a forward commitment basis only with the
intention of completing the transaction and actually purchasing or selling the
securities. No Fund intends to engage in when-issued purchases and forward
commitments for speculative purposes. If deemed advisable as a matter of
investment strategy, however, a Fund may dispose of or renegotiate a commitment
after it is entered into, and may sell securities it has committed to purchase
before those securities are delivered to the Fund on the settlement date. In
these cases a Fund may realize a capital gain or loss.

When a Fund engages in when-issued and forward commitment transactions, it
relies on the other party to consummate the trade. Failure of such party to do
so may result in the Fund's incurring a loss or missing an opportunity to obtain
a price considered to be advantageous.

The value of the securities underlying a when-issued purchase or a forward
commitment to purchase securities, and any subsequent fluctuations in their
value, is taken into account when determining a Fund's net asset value starting
on the day that the Fund agrees to purchase the securities. A Fund does not earn
interest on the securities it has committed to purchase until they are paid for
and delivered on the settlement date. When a Fund makes a forward commitment to
sell securities it owns, the proceeds to be received upon settlement are

-18-
<PAGE>

included in the Fund's assets, and fluctuations in the value of the underlying
securities are not reflected in the Fund's net asset value as long as the
commitment remains in effect.

Zero Coupon Bonds
-----------------

Each Fund may acquire zero coupon bonds. Such obligations will not result
in the payment of interest until maturity and typically have greater price
volatility than coupon obligations. A Fund will accrue income on such
investments for tax and accounting purposes, as required, which is distributable
to shareowners and which, because no cash is received at the time of accrual,
may require the liquidations of other portfolio securities to satisfy the Fund's
distribution obligations. These actions may occur under disadvantageous
circumstances and may reduce a Fund's assets, thereby increasing its expense
ratio and decreasing its rate of return. Zero coupon bonds are subject to
greater market fluctuations from changing interest rates than debt obligations
of comparable maturities which make current distributions of interest.

INVESTMENT LIMITATIONS
----------------------

Each Fund is subject to the investment limitations enumerated below, which
may not be changed with respect to a Fund without the approval of the lesser of
(1) 67% of the Fund's shares present at a meeting of shareowners if the holders
of more than 50% of the outstanding shares are present in person or by proxy or
(2) more than 50% of the Fund's outstanding shares. Other restrictions in the
form of non-fundamental policies are subject to change by The Commerce Funds'
Board of Trustees without shareholder approval. In addition, the Funds'
investment objectives are fundamental and may not be changed without shareowner
approval. If a percentage limitation is satisfied at the time of investment, a
later increase or decrease in such percentage resulting from a change in the
value of a Fund's investments will not constitute a violation of such
limitation, except that any borrowing by a Fund that exceeds the fundamental
investment limitations stated above must be reduced to meet such limitations
within the period required by the 1940 Act (currently three days). Otherwise, a
Fund may continue to hold a security even though it causes the Fund to exceed a
percentage limitation because of the fluctuation in the value of the Fund's
assets.

As a matter of fundamental policy, no Fund may:

1. Purchase or sell real estate, except that a Fund may invest in
securities directly or indirectly secured by real estate or interests therein or
issued by companies which invest in real estate or interests therein and may
hold and sell real estate acquired by a Fund as a result of the ownership of
securities.

2. Make loans to other persons, except that the purchase of all or a
portion of an issue of securities or obligations of the type in which a Fund may
invest shall not be deemed to be the making of a loan, and except further that a
Fund may enter into repurchase agreements in accordance with its investment
objective and policies and may lend its portfolio securities in an amount not to
exceed 33 1/3% of the value of its total assets (including the value of the
collateral for the loan).

-19-
<PAGE>

3. Borrow money, issue senior securities or pledge its assets, except
that a Fund may borrow from banks and enter into reverse repurchase agreements
as a temporary measure for extraordinary or emergency purposes or to meet
redemptions in amounts not exceeding 33 1/3% (taken at market value) of its
total assets (including the amount borrowed) and pledge its assets to secure
such borrowings, provided the Fund maintains assets coverage of at least 300%
for all such borrowings. No Fund will purchase securities while its aggregate
borrowings (including reverse repurchase agreements and borrowings from banks)
in excess of 5% of its total assets are outstanding. Securities held in escrow
or separate accounts in connection with a Fund's investment practices are not
deemed to be pledged for purposes of this limitation.

4. Purchase securities on margin, except that (i) a Fund may obtain
such short-term credit as may be necessary for the clearance of purchases and
sales of portfolio securities, (ii) a Fund may pay initial or variation margin
in connection with futures and related option transactions, and (iii) this
investment limitation shall not apply to a Fund's transactions in futures
contracts and related options or to a Fund's transactions in securities on a
when-issued or forward commitment basis.

5. Underwrite securities of other issuers, except insofar as a Fund
technically may be deemed an underwriter under the Securities Act of 1933, as
amended ("Securities Act") in purchasing and selling portfolio securities and
except insofar as such underwriting would comply with the limits set forth in
the 1940 Act.

6. Purchase or sell commodities or contracts on commodities, except to
the extent a Fund may do so in accordance with applicable law and a Fund's
current prospectus and statement of additional information, as it may be amended
from time to time, and without registering as a commodity pool operator under
the Commodities Exchange Act.

As a matter of fundamental policy:

1. Each of the Funds will limit its investments so that less than 25%
of the Fund's total assets will be invested in the securities of the issuers in
any one industry. For purposes of this restriction, state and municipal
governments and their agencies and instrumentalities, securities issued or
guaranteed by the U.S. Government, its agencies or instrumentalities and
repurchase agreements fully collateralized by securities issued or guaranteed by
the U.S. Government, its agencies or instrumentalities are not deemed to be
industries in connection with the issuance of tax-exempt securities. Thus, a
Fund may invest 25% or more of the value of its total assets in Municipal
Obligations which are related in such a way that an economic, business or
political development or change affecting one Municipal Obligation would also
affect other Municipal Obligations. For example, a Fund may so invest in (a)
Municipal Obligations the interest on which is paid solely from revenues of
similar projects such as hospitals, electric utility systems, multi-family
housing, nursing homes, commercial facilities (including hotels), steel
companies or life care facilities, (b) Municipal Obligations whose issuers are
in the same state, or (c) industrial development obligations. The Funds will not
purchase securities (except U.S. Government Obligations) if more than 5% of its
total assets will be invested in the securities of any

-20-
<PAGE>

one issuer, except that up to 25% of the total assets of the National Tax-Free
Fund, and up to 50% of the total assets of the Missouri Tax-Free Fund, may be
invested without regard to this 5% limitation (although not more than 25% of the
Missouri Tax-Free Fund's total assets will be invested in the securities of any
one issuer).

As a matter of non-fundamental policy, no Fund may:

1. Purchase securities of other investment companies except (a)
purchases which are part of a plan of merger, consolidation, reorganization, or
acquisition, and (b) other purchases of the securities of investment companies
only if the purchases are of open-ended, no-load funds, are conditioned on the
waiver of management fees and further, if immediately thereafter (i) not more
than 3% of the total outstanding voting stock of such company is owned by the
Fund, (ii) not more than 5% of the Fund's total assets, taken at market value,
would be invested in the securities of any one investment company, (iii) not
more than 10% of the Fund's total assets, taken at market value, would be
invested in the aggregate in securities of investment companies as a group, and
(iv) the Fund, together with other investment companies having the same
investment adviser and companies controlled by such companies, owns not more
than 10% of the total outstanding stock of any one investment company.

2. Make short sales of securities or maintain a short position, except
that a Fund may make short sales against-the-box (defined as the extent to which
a Fund contemporaneously owns or has the right to obtain at no added cost
securities identical to those sold short).

3. Invest in illiquid securities if as a result more than 15% of its
net assets would be invested in such securities.

4. Make investments for the purpose of exercising control or
management.

5. Invest in warrants if at the time of acquisition a Fund's investment
in warrants would exceed 10% of the value of the Fund's net assets.

6. Invest in real estate limited partnership interests or
participations or other direct interests in or enter into leases with respect to
oil, gas or other mineral exploration or development programs if, as a result
thereof, more than 5% of the value of the total assets of a Fund would be
invested in such programs, except that a Fund may invest in securities issued by
companies that engage in oil, gas or other mineral exploration of development
activities.

7. Write, purchase or sell puts, calls, straddles, spreads or
combinations thereof with respect to more than 5% of the value of its net
assets.

PRICING OF SHARES

The net asset value per share for each Fund of The Commerce Funds is
calculated separately for Service Shares by adding the value of all portfolio
securities and other assets

-21-
<PAGE>

belonging to the Fund that are allocable to that particular class, subtracting
the liabilities charged to such class of the Fund, and dividing the result by
the number of shares outstanding of such class of the Fund. Assets which belong
to the Fund consist of the consideration received upon the issuance of shares of
the Fund together with all income, earnings, profits and proceeds derived from
the investment thereof, including any proceeds from the sale of such
investments, any funds or payments derived from any reinvestment of such
proceeds, and a portion of any general assets of The Commerce Funds not
belonging to a particular investment portfolio. Assets belonging to a particular
class of a Fund are charged with the direct liabilities of that class and with a
share of the general liabilities of The Commerce Funds which are normally
allocated in proportion to the relative net asset values of all of The Commerce
Funds' investment portfolios at the time of allocation. Payments under The
Commerce Funds' Shareholder Administrative Services Plans for Service Shares are
allocated to the Shares in proportion to the relative net asset values of the
Funds.

As stated in their Prospectuses, a Fund's investments will be valued at
market value or, in the absence of a market value with respect to any portfolio
securities, at fair value as determined by or under the direction of The
Commerce Funds' Board of Trustees. A security that is primarily traded on a
domestic securities exchange (including securities traded through the National
Market System) is valued at the last sale price on that exchange or, if there
were no sales during the day, at the current quoted bid price. Securities traded
on only over-the-counter markets are valued on the basis of closing
over-the-counter bid prices. Securities for which there were no transactions are
valued at the average of the current bid and asked prices. Restricted securities
and securities for which market quotations are not readily available are valued
at fair value as determined in good faith by the Board of Trustees.

The value of a Fund's portfolio securities that are traded on stock
exchanges outside the United States are based upon the price on the exchange as
of the close of business of the exchange immediately preceding the time of
valuation, except when an occurrence subsequent to the time a value was so
established is likely to have changed such value; then the fair value of those
securities will be determined through consideration of other factors by or under
the direction of The Commerce Funds' Board of Trustees. Securities trading in
over-the-counter markets in European and Pacific Basin countries is normally
completed well before 4:00 p.m. Eastern time. In addition, European and Pacific
Basin securities trading may not take place on all Business Days (as defined in
the Prospectus). Furthermore, trading takes place in Japanese markets on certain
Saturdays and in various foreign markets on days which are not considered to be
Business Days. The calculation of the net asset value of the Funds may not take
place contemporaneously with the determination of the prices of portfolio
securities used in such calculation. Events affecting the values of portfolio
securities that occur between the time their prices are determined and 4:00 p.m.
Eastern time, and at other times may not be reflected in the calculation of net
asset value of the Funds.

ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

Shares of the Funds are offered and sold on a continuous basis by The
Commerce Funds' Distributor, Goldman, Sachs & Co., acting as agent for The
Commerce Funds. Service

-22-
<PAGE>

Shares of the Funds are sold to investors at the public offering price based on
a Fund's net asset value plus a front-end sales charge as described in the
Prospectus.

Service Shares are offered primarily to:

. individuals, corporations or other entities, purchasing for their own
accounts or for the accounts of others, and to qualified banks, savings
and loan associations, and broker/dealers on behalf of their customers;
and

. financial planners and their clients.

Additional Redemption Information
---------------------------------

Under the 1940 Act, a Fund may suspend the right of redemption or postpone
the date of payment for shares during any period when (a) trading on the New
York Stock Exchange is restricted by applicable rules and regulations of the
SEC; (b) the Exchange is closed for other than customary weekend and holiday
closing; (c) the SEC has by order permitted such suspension; or (d) an emergency
exists as determined by the SEC. (The Commerce Funds may also suspend or
postpone the recordation of the transfer of shares upon the occurrence of any of
the foregoing conditions.)

In addition to the situations described in the Prospectuses under "How To
Sell Shares," The Commerce Funds may redeem shares involuntarily to reimburse
the Funds for any loss sustained by reason of the failure of a shareholder to
make full payment for shares purchased by the shareholder or to collect any
charge relating to a transaction effected for the benefit of a shareholder which
is applicable to shares of the Funds as provided in the Prospectuses.

In an exchange, the redemption of shares being exchanged will be made at
the per share net asset value of the shares to be redeemed next determined after
the exchange request is received. The shares of the Fund to be acquired will be
purchased at the per share net asset value of those shares (plus any applicable
sales charge) next determined after acceptance of the purchase order by The
Commerce Funds in accordance with its customary policies for accepting
investments.

A Fund may make payment for redemption in securities or other property if
it appears appropriate to do so in light of the Fund's responsibilities under
the 1940 Act. In the event shares are redeemed for securities or other property,
shareowners may incur additional costs in connection with the conversion thereof
to cash. Redemption in kind is not as liquid as a cash redemption. Shareowners
who receive a redemption in kind may receive less than the redemption value of
their shares upon sale of the securities or property received, particularly
where such securities are sold prior to maturity.

<PAGE>

DESCRIPTION OF SHARES

Under the Funds' Trust Instrument, the shares of beneficial interest in
The Commerce Funds shall be divided into such transferable shares of one or more
separate and distinct series or classes of a series, as the Trustees shall from
time to time create and establish. The Trustees may, from time to time and
without vote of the shareowners, issue shares to a party or parties and for such
amount and type of consideration and on such terms, subject to applicable law,
as the Trustees may deem appropriate. The Trustees may issue fractional shares
and shares held in the treasury. Also, the Trustees may from time to time divide
or combine the shares into a greater or lesser number without thereby changing
the proportionate beneficial interests in The Commerce Funds. The proceeds
received by each Fund for each issue or sale of its shares, and all net
investment income, realized and unrealized gain and proceeds thereof, subject
only to the rights of creditors, will be specifically allocated to and
constitute the underlying assets of that Fund. The underlying assets of each
Fund will be segregated on the books of account.

Each Fund is authorized to issue two classes of shares: Institutional
Shares and Service Shares.

Fund shares have no preemptive rights and only such conversion and
exchange rights as the Board of Trustees may grant in its discretion. All shares
issued as described in the Prospectuses will be fully paid and non-assessable.

Each share of a series shall represent an equal beneficial interest in the
net assets of such series. Each holder of shares of a series shall be entitled
to receive distributions of income and capital gains, if any, which are made
with respect to such series and which are attributable to such shares. Upon
redemption of shares, such shareowner shall be paid solely out of the funds and
property of such series of The Commerce Funds.

The Trustees shall have full power and authority, in their sole
discretion, and without obtaining any prior authorization or vote of shareowners
of any series of The Commerce Funds, to establish and designate and to change in
any manner any such series of shares or any classes of initial or additional
series and to fix such relative preferences, voting powers, rights and
privileges of such series or classes thereof as the Trustees may from time to
time determine, to divide or combine the shares or any series or classes thereof
into a greater or lesser number, to classify or reclassify any issued shares or
any series or classes thereof into one or more series or classes of shares, and
to take such other action with respect to the shares as the trustees may deem
desirable.

In the event of a liquidation or dissolution of The Commerce Funds or an
individual Fund, the Trustees may sell and convey all or substantially all of
the assets of The Commerce Funds or any series to another entity or to a
separate series of shares thereof, for adequate consideration. The sale or
conveyance may include the assumption of all outstanding obligations, taxes and
other liabilities and may include shares of beneficial interest, stock or other
ownership interests. In the alternative, the Trustees may sell and convert into
money all of the assets of The Commerce Funds or any series. After such actions,
the Trustees will distribute the

-24-
<PAGE>

remaining proceeds or assets (as the case may be) of each series (or class)
ratably among the holders of shares of those series then outstanding.

Rule 18f-2 under the 1940 Act provides that any matter required by the
provisions of the 1940 Act or applicable state law, or otherwise, to be
submitted to the holders of the outstanding voting securities of an investment
company shall not be deemed to have been effectively acted upon unless approved
by the holders of a majority of the outstanding shares of each investment
portfolio affected by such matter. Rule 18f-2 further provides that an
investment portfolio shall be deemed to be affected by a matter unless the
interests of each investment portfolio in the matter are substantially identical
or the matter does not affect any interest of the investment portfolio. Under
the Rule, the approval of an investment advisory agreement or any change in a
fundamental investment policy would be effectively acted upon with respect to an
investment portfolio only if approved by a majority of the outstanding shares of
such investment portfolio. However, the Rule also provides that the ratification
of the appointment of independent accountants, the approval of principal
underwriting contracts and the election of Trustees may be effectively acted
upon by shareowners of The Commerce Funds voting together in the aggregate
without regard to a particular investment portfolio.

The shareowners have the power to vote only for the election of Trustees,
for the removal of Trustees and with respect to such additional matters relating
to The Commerce Funds as may be required by law, by the Trust Instrument, or as
the Trustees may consider desirable. The Trustees may also determine that a
matter affects only the interests of one or more classes of a series, in which
case any such matter shall be voted on by such class or classes. Each whole
share shall be entitled to one vote as to any matter on which it is entitled to
vote, and each fractional share shall be entitled to a proportionate fractional
vote. There shall be no cumulative voting in the election of Trustees. Shares
may be voted in person or by proxy or in any manner provided for in the By-laws.
A proxy may be given in writing, by telefax, or in any other manner provided for
in the By-laws.

Special meetings of the shareowners of any series may be called by the
Trustees and shall be called by the Trustees upon the written request of
shareowners owning at least 10% of the outstanding shares entitled to vote.
Whenever ten or more shareowners meeting the qualifications set forth in Section
16(c) of the 1940 Act seek the opportunity of furnishing materials to the other
shareowners with a view to obtaining signatures on such a request for a meeting,
the Trustees shall provide shareowners access to The Commerce Funds' list of
record shareowners or the mailing of such materials to such record shareowners,
subject to the applicable provisions of the 1940 Act. Notice shall be sent by
mail or such other means as determined by the Trustees at least 15 days prior to
any such meeting. One-third of the shares entitled to vote in person or by proxy
shall be a quorum for the transaction of business at a shareowners' meeting,
except that where any provision of law or of the Trust Instrument permits or
requires that holders of any series shall vote as a series (or that holders of a
class shall vote as a class), then one-third of the aggregate number of shares
of that series (or that class) entitled to vote shall be necessary to constitute
a quorum for the transaction of business by that series (or that class). Any
action which may be taken by the shareowners of The Commerce Funds or of a
series may be taken without a meeting if shareowners holding more than a
majority of the shares

-25-
<PAGE>

entitled to vote, except when a larger vote is required by law or by any
provision of the Trust Instrument, shall consent to the action in writing,
provided that such action by written consent is approved by the Board of
Trustees.

When used in the Prospectuses or in this Statement of Additional
Information, a "majority" of shareowners of The Commerce Funds or a particular
Fund means, with respect to the approval of an investment advisory agreement or
a change in an investment objective or a fundamental investment policy, the vote
of the lesser of (1) 67% of the shares of The Commerce Funds or a Fund present
at a meeting if the holders of more than 50% of the outstanding shares are
present in person or by proxy, or (2) more than 50% of the outstanding shares of
The Commerce Funds or a Fund.

The Trust Instrument provides that the Trustees, when acting in their
capacity, will not be personally liable to any person other than The Commerce
Funds or a beneficial owner for any act, omission or obligation of The Commerce
Funds or any Trustee. A Trustee shall not be liable for any act or omission in
his capacity as Trustee, or for any act or omission of any officer or employee
of The Commerce Funds or of any other person or party, provided that nothing
contained in the Trust Instrument or in the Delaware Business Trust law shall
protect any Trustee against any liability to The Commerce Funds or to
shareowners to which he would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of the office of Trustee.

ADDITIONAL INFORMATION CONCERNING TAXES

Federal Taxes

Each Fund intends to qualify as a regulated investment company under
Subchapter M of the Internal Revenue Code, and to distribute out its income to
shareholders each year, so that each Fund itself generally will be relieved of
federal income and excise taxes. If a Fund were to fail to so qualify: (1) the
Fund would be taxed at regular corporate rates without any deduction for
distributions to shareholders; and (2) shareholders would be taxed as if they
received ordinary dividends, although corporate shareholders could be eligible
for the dividends received deduction.

Federal Tax-Exempt Information

The Funds' distributions will generally constitute tax-exempt income for
shareowners for federal income tax purposes. It is possible, depending upon the
Funds' investments, that a portion of the Funds' distributions could be taxable
to shareowners as ordinary income or capital gains, but the Funds do not expect
that this will be the case.

State and local income taxes generally apply to interest on bonds of
states and political subdivisions outside of the state in which the tax is
imposed. Missouri exempts interest on (i) its own obligations, (ii) the
obligations of its political subdivisions, (iii) U.S. Government

-26-
<PAGE>

obligations, and (iv) obligations of certain U.S. territories and possessions,
from its personal income tax and general corporate income tax. The Funds'
distributions from these sources will retain their exempt character in the hands
of shareowners.

Interest on indebtedness incurred by a shareholder to purchase or carry
shares of the Funds generally will not be deductible for federal income tax
purposes.

You should note that a portion of the exempt-interest dividends paid by
the Funds may constitute an item of tax preference for purposes of determining
federal alternative minimum tax liability. Exempt-interest dividends will also
be considered along with other adjusted gross income in determining whether any
Social Security or Railroad Retirement payments received by you are subject to
federal income taxes.

Certain of the officers and the organizations with which they are
associated have had in the past, and may have in the future, transactions with
Goldman Sachs and its respective affiliates. The Commerce Funds has been advised
by such officers that all such transactions have been and are expected to be in
the ordinary course of business and the terms of such transactions, including
all loans and loan commitments by such persons, have been and are expected to be
substantially the same as the prevailing terms for comparable transactions for
other customers. Messrs. McNamara, Fortner, Perlowski and Surloff and Ms.
Belanger hold similar positions with one or more investment companies that are
advised by Goldman Sachs.

Effective July 26, 2000, each Trustee of the Company receives a fee of
$2,000 for each regular meeting of the Board of Trustees attended, plus $750 for
each special meeting of the Board attended. In addition, the Chairman of the
Board receives an annual fee of $2,000 for his services in this capacity. All
Trustees are reimbursed for out of pocket expenses incurred in connection with
attendance at meetings. Drinker Biddle & Reath LLP, of which Mr. McConnel is a
partner, receives legal fees as counsel to the Trust.

Each Trustee is entitled to participate in The Commerce Funds Deferred
Compensation Plan (the "Plan"). Under the Plan, a Trustee may elect to have his
or her deferred fees treated as if they had been invested by The Commerce Funds
in the shares of one or more portfolios in The Commerce Funds, and the amount
paid to the Trustees under the Plan will be determined based upon the
performance of such investments. Deferral of Trustees' fees will have no effect
on a portfolio's assets, liabilities, and net income per share, and will not
obligate The Commerce Funds to retain the services of any Trustee or obligate a
portfolio to any level of compensation to the Trustee. The Commerce Funds may
invest in underlying securities without shareowner approval.

The following chart provides certain information about the Trustee fees
paid by the Trust for the fiscal year ended October 31, 1999:

Chairman was not entitled to receive any fees for his services in this
capacity. During this period, the following Trustees deferred the amounts
shown pursuant to the Plan: Eric Helsing ($6,000) and David L. Bodde
($6,000).

As of October 4, 2000, the Trustees and officers of The Commerce
Funds as a group held less than 1% of each of the Institutional and Service
Classes of the Funds.

Investment Advisor
------------------

The Funds are advised by Commerce Bank, N.A., a subsidiary of
Commerce Bancshares, Inc., a registered multi-bank holding company. Commerce
Bank, N.A. (or its predecessor organizations) have provided investment
management services to The Commerce Funds since 1994, to private and public
pension funds, endowments and foundations since 1946 and to individuals since
1906.

In the Advisory Agreement with The Commerce Funds, the Advisor has
agreed to manage each Fund's investments and to be responsible for, place orders
for, and make decisions with respect to, all purchases and sales of each Fund's
securities. For the advisory services provided and expenses assumed under the
Advisory Agreement, the Advisor is entitled to receive a fee calculated as a
percentage of the Funds' average daily net assets as stated below:

Annual Rate

For the fiscal years ended October 31, 1999 and 1998 and 1997, the
Advisor voluntarily agreed to waive a portion of its advisory fee for certain
portfolios. During the periods stated, these waivers reduced advisory fees by
the following:

In addition, for the fiscal years ended October 31, 1999, 1998 and
1997, the Advisor voluntarily agreed to reimburse the expenses of certain of the
Funds. The effect of these reimbursements during the period was to reduce
expenses as follows:

Missouri Tax-Free Intermediate Bond
Fund $26,626 $50,592 $116,567
</TABLE>

Under the terms of the Advisory Agreement, the Advisor is obligated
to manage the investment of the Funds' assets in accordance with applicable laws
and regulations, including, to the extent applicable, the regulations and
rulings of the U.S. Comptroller of the Currency relating to fiduciary powers of
national banks. These regulations provide, in general, that assets managed by a
national bank as fiduciary may not be invested in stock or obligations of, or
property acquired from, the bank, its affiliates or their directors, officers or
employees, and further provide that fiduciary assets may not be sold or
transferred, by loan or otherwise, to the bank or persons connected with the
bank as described above.

-32-
<PAGE>

The Advisor will not accept The Commerce Funds' shares as collateral
for a loan which is for the purpose of purchasing The Commerce Funds' shares,
and will not make loans to The Commerce Funds. Inadvertent overdrafts of The
Commerce Funds' account with the Custodian occasioned by clerical error or by
failure of a shareholder to provide available funds in connection with the
purchase of shares will not be deemed to be the making of a loan to The Commerce
Funds by the Advisor.

The Advisor's own investment portfolio may include bank certificates
of deposit, bankers' acceptances, and corporate debt obligations, any of which
may also be purchased by The Commerce Funds. Joint purchase of investments for
The Commerce Funds and for the Advisor's own investment portfolio will not be
made. The Advisor's Commercial Banking Department may have deposit, loan and
other commercial banking relationships with issuers of securities purchased by
The Commerce Funds, including outstanding loans to such issuers which may be
repaid in whole or in part with the proceeds of securities purchased by The
Commerce Funds.

Under the Advisory Agreement, the Advisor is not liable for any
error of judgment or mistake of law or for any loss suffered by The Commerce
Fund in connection with the performance of such Agreement, except a loss
resulting from a breach of fiduciary duty with respect to the receipt of
compensation for services or a loss resulting from willful misfeasance, bad
faith or gross negligence on the part of the Advisor in the performance of its
duties or from its reckless disregard of its duties and obligations under the
Agreement.

Custodian and Transfer Agent
----------------------------

State Street Bank serves as Custodian of each Fund's assets pursuant
to a Custody Agreement under which it has agreed, among other things, to (i)
maintain a separate account in the name of each Fund; (ii) hold and disburse
portfolio securities on account of each Fund; (iii) collect and receive all
income and other payments and distributions on account of each Fund's portfolio
investments; (iv) make periodic reports to The Commerce Funds concerning each
Fund's operations; (v) provide various accounting services to The Commerce Funds
and to the Administrator for the benefit of The Commerce Funds; and (vi) act as
foreign custody manager pursuant to Rule 17f-5 of the 1940 Act with respect to
the monitoring of the Funds' assets held by eligible foreign sub-Custodians. The
Custodian is authorized to select one or more banks or trust companies to serve
as sub-Custodian on behalf of the Funds, provided that the Custodian shall
remain liable for the performance of all of its duties under its respective
Custody Agreement and will hold The Commerce Funds and Funds harmless from
losses caused by the negligence or willful misconduct of any bank or trust
company serving as sub-Custodian. State Street is located at 225 Franklin
Street, Boston, Massachusetts 02110.

As compensation for custodial services provided, The Commerce Funds
will pay the Custodian fees of 1/100th of 1% of a Fund's average monthly net
assets up to one billion, 1/133rd of 1% of the next one billion of such assets
and 1/200th of 1% of such assets in excess of

-33-
<PAGE>

two billion based on the aggregate average daily net assets of the Funds, plus a
transaction charge for certain transactions and out-of-pocket expenses.

State Street Bank also serves as the Funds' Transfer Agent and
dividend disbursing agent. State Street has appointed NFDS, an indirect
subsidiary, to act as the Funds' Transfer Agent, as permitted in the Transfer
Agency Agreement, provided that State Street Bank shall remain liable for the
performance of all of its duties and will hold The Commerce Funds and Fund or
Funds harmless from losses caused by the negligence or willful misconduct of any
appointee. Under the Transfer Agency Agreement, NFDS will, among other things,
(i) receive purchase orders and redemption requests for shares of the Funds;
(ii) issue and redeem shares of the Funds; (iii) effect transfers of shares of
the Funds; (iv) prepare and transmit payments for dividends and distributions
declared by the Funds; (v) maintain records of accounts for the Funds,
shareowners and advise each shareholder to the foregoing; (vi) record the
issuance of shares of each Fund and maintain a record of and provide the Fund on
a regular basis with the total number of shares of each Fund which are
authorized, issued and outstanding; (vii) perform the customary services of a
Transfer Agent, a dividend disbursing agent and Custodian of certain retirement
plans and, as relevant, agent in connection with accumulation, open account or
similar plans; and (viii) provide a system enabling the Funds to monitor the
total number of shares sold in each State.

Administrator
-------------

Goldman Sachs Asset Management is the Administrator for the Funds.
GSAM is located at 32 Old Slip, New York, New York 10005. GSAM is a unit of the
Investment Management Division of Goldman, Sachs & Co., the Distributor of the
Funds. Under the Administration Agreement with The Commerce Funds, GSAM
administers the business affairs of The Commerce Funds, subject to the
supervision of the Board of Trustees, and in connection therewith, furnishes The
Commerce Funds with office facilities and is responsible for ordinary clerical,
recordkeeping and bookkeeping services required to be maintained by The Commerce
Funds (excluding those maintained by The Commerce Funds' Custodian, Transfer
Agent, Advisor and any Sub-Advisor), preparation and filing of documents
required to comply with federal and state securities laws, supervising the
activities of the Custodian and Transfer Agent, providing assistance in
connection with meetings of the Board of Trustees and shareowners and other
administrative services necessary to conduct the business of The Commerce Funds.
For these services and facilities, GSAM is entitled to receive a monthly fee
from each Fund at an annual rate of 0.15% of its average daily net assets. For
the fiscal year ended October 31, 1999, GSAM received administration fees at the
annual rate of 0.15% of the average daily net assets of each Fund. For the
fiscal years ended October 31, 1999, 1998 and 1997, the fees paid by the Funds
for administration services were as follows:

Distributor
-----------

The Commerce Funds' shares are offered on a continuous basis through
Goldman, Sachs & Co., which acts under the Distribution Agreement as Distributor
for The Commerce Funds. Goldman is located at 85 Broad Street, New York, New
York 10004. Goldman, Sachs & Co. may receive a portion of the sales load imposed
on the sale of shares of the Funds and has advised The Commerce Funds that it
has retained approximately $18,000, $22,000 and $47,000 of such sales loads for
the fiscal years ended October 31, 1999, 1998 and 1997, respectively.

THE DISTRIBUTION PLAN AND THE SHAREHOLDER ADMINISTRATIVE
SERVICES PLANS

The Distributor is entitled to payment on a monthly basis at an
annual rate not exceeding 0.25% of the average daily net assets of Service
Shares from the Trust for distribution expenses incurred pursuant to the
Distribution Plan (the "12b-1 Plan") adopted on behalf of the Service Shares.
Under the 12b-1 Plan, the Trust may pay the Distributor (or any other person)
for: (i) direct out-of-pocket promotional expenses incurred by the Distributor
in advertising and marketing Service Shares; (ii) expenses incurred in
connection with preparing, printing, mailing, and distributing or publishing
advertisements and sales literature for Service Shares; (iii) expenses incurred
in connection with printing and mailing prospectuses and statements of
additional information to other than current Service Class shareowners; (iv)
periodic payments or commissions to one or more securities dealers, brokers,
financial institutions or other industry professionals, such as investment
advisors, accountants, and estate planning firms with respect to a Fund's
Service Shares beneficially owned by customers for whom the distribution
organization is the record or holder of record of such Service Shares; or (v)
for such other services as may be construed, by any court or governmental agency
or commission, including the Securities and Exchange Commission, to constitute
distribution services under the 1940 Act or rules and regulations thereunder.

During the fiscal year ended October 31, 1999, The Commerce Funds
paid the Distributor $56,082 in the aggregate under the Funds' 12b-1 Plan.

The Commerce Funds may enter into Servicing Agreements with Service
Organizations, which may include the Advisor and its affiliates, pursuant to the
Shareholder Administrative Services Plan for Service Shares (the "Services
Plan"). The Servicing Agreements provide that the Service Organizations will
render shareholder administrative support services to their customers who are
the beneficial owners of Service Shares of the Funds

-35-
<PAGE>

in consideration for a Fund's payment of up to 0.25% (on an annualized basis) of
the average daily net asset value of the shares of the Fund beneficially owned
by such customers and held by the Service Organizations. At The Commerce Fund's
option, it may reimburse the Service Organizations' out-of-pocket expenses as
well. Such services may include: (i) processing dividend and distribution
payments from a Fund; (ii) providing information periodically to customers
showing their share positions in Service Shares; (iii) arranging for bank wires;
(iv) responding to customer inquiries concerning their investments in shares;
(v) providing subaccounting with respect to shares beneficially owned by
customers or the information necessary for such subaccounting; (vi) if required
by law, forwarding shareholder communications; (vii) processing share exchange
and redemption requests from customers; (viii) assisting customers in changing
dividend options, account designations and addresses; (ix) establishing and
maintaining accounts and records relating to customers that invest in shares;
(x) responding to customer inquiries relating to the services performed by the
Service Organization; and (xi) other similar services requested by the Commerce
Funds. Banks acting as Service Organizations are prohibited from engaging in any
activity primarily intended to result in the sale of Fund shares. However,
Service Organizations other than banks may be requested to provide marketing
assistance (e.g., forwarding sales literature and advertising to their
customers) in connection with the distribution of Fund shares.

The Services Plans are subject to annual reapproval by a majority of
the Trust's Board of Trustees, including a majority of the Non-Interested
Trustees, and is terminable without penalty at any time with respect to any Fund
by a vote of a majority of the Non-Interested Trustees or by vote of the holders
of a majority of the outstanding shares of each Class of the Fund involved. Any
agreement entered into pursuant to the Services Plans with a Service
Organization is terminable with respect to any Fund without penalty, at any
time, by vote of a majority of the Non-Interested Trustees, by vote of the
holders of a majority of the outstanding shares of each Class of such Fund, or
by the Service Organizations. Each agreement will also terminate automatically
in the event of its assignment.

The Trust's Board of Trustees has concluded that there is a
reasonable likelihood that the Services Plans will benefit the Funds and their
shareowners.

PORTFOLIO TRANSACTIONS

Brokerage Transactions and Commissions
--------------------------------------

Transactions on U.S. stock exchanges involve the payment of
negotiated brokerage commissions. On exchanges on which commissions are
negotiated, the cost of the Funds' transactions may vary among different
brokers. Transactions in the over-the-counter market are generally principal
transactions with dealers and the costs of such transactions involve dealer
spreads rather than brokerage commissions. With respect to over-the-counter
transactions, the Advisor will normally deal directly with the dealers who make
a market in the securities involved except in those circumstances where better
prices and execution are available elsewhere or as described below. Unlike
transactions on U.S. stock exchanges which involve the payment

-36-
<PAGE>

of negotiated brokerage commissions, transactions in foreign securities
generally involve the payment of fixed brokerage commissions, which are
generally higher than those in the United States.

Debt securities purchased and sold by the Funds are generally traded
in the over-the-counter market on a net basis (i.e., without commission) through
dealers, or otherwise involve transactions directly with the issuer of an
instrument. The cost of securities purchased from underwriters includes an
underwriting commission or concession, and the prices at which securities are
purchased from and sold to dealers include a dealer's mark-up or mark-down.

The Advisory Agreements for the Funds provide that, in executing
portfolio transactions and selecting brokers or dealers, the Advisor will use
reasonable efforts to seek the best overall terms available on behalf of each
Fund. In assessing the best overall terms available for any transaction, the
Advisor will consider all factors it deems relevant, including the breadth of
the market in the security, the price of the security, the financial condition
and execution capability of the broker or dealer, and the reasonableness of the
commission, if any, both for the specific transaction and on a continuing basis.
In addition, the Agreements authorize the Advisor, subject to the prior approval
of the Board of Trustees, to cause the Funds to pay a broker/dealer furnishing
brokerage and research services a higher commission than that which might be
charged by another broker-dealer for effecting the same transaction, provided
that it determines in good faith that such commission is reasonable in relation
to the value of the brokerage and research services provided by such
broker/dealer, viewed in terms of either that particular transaction or the
overall responsibilities of the Advisor to the particular Fund and to The
Commerce Funds. Such brokerage and research services might consist of reports
and statistics of specific companies or industries, general summaries of groups
of stocks or bonds and their comparative earnings and yields, broad overviews of
the stock, bond and government securities markets and the economy, and advice as
to the value of securities, as well as the advisability of investing in,
purchasing or selling securities and the availability of securities or
purchasers or sellers of securities.

Supplementary research information so received is in addition to,
and not in lieu of, services required to be performed by the Advisor and does
not reduce the advisory fees payable by the Funds. The Board of Trustees will
periodically review the commissions paid by the Funds to consider whether the
commissions paid over representative periods of time appear to be reasonable in
relation to the benefits inuring to the Funds. It is possible that certain
supplementary research or other services received will primarily benefit one or
more other investment companies or other accounts for which investment
discretion is exercised. Conversely, a Fund may be the primary beneficiary of
the research or services received as a result of portfolio transactions effected
for such other account or investment company.

A Fund's portfolio securities will not be purchased from or sold to
(and savings deposits will not be made in and repurchase and reverse repurchase
agreements will not be entered into with) the Advisor, Sub-Advisor, Goldman,
Sachs & Co. or any affiliated person (as such term is defined in the 1940 Act)
thereof acting as principal or broker, except to the extent permitted by the
SEC. However, The Commerce Funds' Board of Trustees has authorized the

-37-
<PAGE>

Advisor to allocate purchase and sale orders for portfolio securities to
broker/dealers and other financial institutions including, in the case of agency
transactions, institutions which are affiliated with the Advisor, to take into
account the sale of Fund shares if the Advisor believes that the quality of the
transaction and the amount of the commission are comparable to what they would
be with other qualified brokerage firms, provided such transactions comply with
the requirements of Rule 17e-1 under the 1940 Act. In addition, the Funds will
not purchase securities during the existence of any underwriting or selling
group relating thereto of which the Advisor, Goldman, Sachs & Co., or any
affiliated person thereof is a member, except to the extent permitted by the
SEC. Under certain circumstances, the Funds may be at a disadvantage when
compared to other investment companies which have similar investment objectives
but that are not subject to such limitations.

Investment decisions for each Fund are made independently from those
made for the other Funds and from those made for other investment companies and
accounts advised or managed by the Advisor. Such other investment companies and
accounts may also invest in the same securities as the Funds. When a purchase or
sale of the same security is made at substantially the same time on behalf of
any Fund and another investment company or account, that transaction will be
aggregated (where not inconsistent with the policies set forth in the
Prospectuses) and allocated as to amount in a manner which the Advisor believes
to be equitable and consistent with its fiduciary obligations to the Fund
involved and such other investment company or account. In some instances, this
investment procedure may adversely affect the price paid or received by a Fund
or the size of the position obtained by a Fund.

During the fiscal year ended October 31, 1999, the Missouri Tax-Free
Intermediate Bond Fund entered into repurchase agreement transactions with State
Street Bank and Trust Company, which was one of the broker/dealers that engaged
as principal in the largest dollar amount of portfolio transactions with the
Fund. At October 31, 1999, the value of the Fund's outstanding repurchase
agreement transactions with State Street Bank and Trust Company was as follows:

Missouri Tax-Free Intermediate Bond Fund $223,000

ADDITIONAL INFORMATION ON PERFORMANCE

From time to time, yield and total return of the Funds for various
periods may be quoted in advertisements, shareholder reports or other
communications to shareowners. The performance of each Fund may also be compared
to those of other mutual funds with similar investment objectives and to stock,
bond and other relevant indices or to rankings prepared by independent services
or other financial or industry publications that monitor the performance of
mutual funds.

Yield Calculations. A Fund's yield is calculated by dividing its net
------------------
investment income per share (as described below) earned during a 30-day period
by the maximum offering price per share on the last day of the period and
annualizing the result on a semi-annual basis by adding one to the quotient,
raising the sum to the power of six, subtracting one from the result and then
doubling the difference. A Fund's net investment income per share earned during
the period may be different than that determined for accounting purposes and is
based on the average daily number of shares outstanding during the period
entitled to receive dividends and includes dividends and interest earned during
the period minus expenses accrued for the period, net of reimbursements. This
calculation can be expressed as follows:

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 outstanding
during the period that were entitled to receive
dividends.

d = maximum offering price per share on the last
day of the period.

For the purpose of determining net investment income earned during
the period (variable "a" in the formula), dividend income on equity securities
held by a Fund is recognized by accruing 1/360 of the stated dividend rate of
the security each day that the security is held in its portfolio. A Fund
calculates interest earned on any debt obligations held in its portfolio by
computing the yield to maturity of each obligation held by it based on the
market value of the obligation (including actual accrued interest) at the close
of business on the last business day of each month, or, with respect to
obligations purchased during the month, the purchase price (plus actual accrued
interest), and dividing the result by 360 and multiplying the quotient by the
market value of the obligation (including actual accrued interest) in order to
determine the interest

-39-
<PAGE>

income on the obligation for each day of the subsequent month that the
obligation is in the portfolio. For purposes of this calculation, it is assumed
that each month contains 30 days. The maturity of an obligation with a call
provision is the next call date on which the obligation reasonably may be
expected to be called or, if none, the maturity date. With respect to debt
obligations purchased at a discount or premium, the formula generally calls for
amortization of the discount or premium. The amortization schedule will be
adjusted monthly to reflect changes in the market values of such debt
obligations.

With respect to mortgage-related obligations which are expected to
be subject to monthly payments of principal and interest ("pay downs"), (a) gain
or loss attributable to actual monthly pay downs are accounted for as an
increase or decrease to interest income during the period; and (b) a Fund may
elect either (i) to amortize the discount and premium on the remaining security,
based on the cost of the security, to the weighted average maturity date, if
such information is available, or to the remaining term of the security, if any,
if the weighted average maturity date is not available, or (ii) not to amortize
discount or premium on the remaining security.

Undeclared earned income may be subtracted from the maximum offering
price per share (variable "d" in the formula). Undeclared earned income is the
net investment income which, at the end of the 30-day base period, has not been
declared as a dividend, but is reasonably expected to be and is declared as a
dividend shortly thereafter.

Prior to ____________, the National Tax-Free Intermediate Bond and
Missouri Tax-Free Intermediate Bond Funds did not offer Service Shares. Based on
the foregoing calculations, for the 30-day period ended October 31, 1999, the

and Missouri Tax-Free Intermediate Bond Funds, were as follows:

asset value on the last day of the period and then annualizing such amount. For
the 30 day period ended October 31, 1999, the

A tax-exempt Fund's "tax-equivalent" yield is computed as follows:
(a) by dividing the portion of the Fund's yield (calculated as above) that is
exempt from both federal and state income taxes by one minus a stated combined
federal and state income tax rate; (b) dividing the portion of the Fund's yield
(calculated as above) that is exempt from federal income tax by one minus a
stated federal income tax rate; and (c) adding the quotient to that portion, if
any, of the Fund's yield that is not exempt from federal income tax.

The tax-equivalent yields for the 30-day period ended October 31,
1999 for Institutional Shares of the National Tax-Free Intermediate Bond Fund
and Missouri Tax-Free Intermediate Bond Fund, with and without fee waivers
(assuming a 39.6% federal tax rate for both Funds and a 6.0% Missouri tax rate
for the Missouri Tax-Free Intermediate Bond Fund) were as follows:

charged to all shareowner accounts are included. The ending redeemable value
(variable "ERV" in the formula) is determined by assuming completed redemption
of the hypothetical investment after deduction of all nonrecurring charges at
the end of the measuring period. In addition, the Funds' yields and distribution
rates will reflect the deduction of the maximum sales load charged in connection
with purchases of shares. The yield and distribution rate calculations do not
include fees that may be imposed by institutions on their customers. If the
foregoing fees had been included in the yields and distribution rates reported
above, performance of these Funds would have been lower. For current yield
information, please contact The Commerce Funds at the telephone number on the
cover page of this Statement of Additional Information.

Total Return Calculations. Each Fund computes its "average annual
-------------------------
total return" by determining the average annual compounded rates of return
during specified periods that equate the initial amount invested to the ending
redeemable value of such investment. This is done by dividing the ending
redeemable value of a hypothetical $1,000 initial payment by $1,000 and raising
the quotient to a power equal to one divided by the number of years (or
fractional portion thereof) covered by the computation and subtracting one from
the result. This calculation can be expressed as follows:

-42-
<PAGE>

P (1 + T)n = ERV

Where: P = hypothetical initial payment of $1,000.

T = average annual total return.

n = number of years.

ERV = ending redeemable value at the
end of the period covered by the
computation of a hypothetical
$1,000 payment made at the
beginning of the 1, 5 or 10 year
periods at the end of the 1, 5
or 10 year periods (or fraction
thereof).

The Funds compute their "aggregate total return" by determining the
aggregate rates of return during specified periods that likewise equate the
initial amount invested to the ending redeemable value of such investment. The
formula for calculating aggregate total return is as follows:

T = (ERV - 1)
-------
P

The calculations of average annual total return and aggregate total
return assume the reinvestment of all dividends and capital gain distributions
on the reinvestment dates during the period and include all recurring fees
charged to all shareholder accounts, assuming an account size equal to the
Fund's mean (or median) account size for any fees that vary with the size of the
account. The maximum sales load and other charges deducted from payments are
deducted from the initial $1,000 payment (variable "P" in the formula). The
ending redeemable value (variable "ERV" in each formula) is determined by
assuming complete redemption of the hypothetical investment and the deduction of
all nonrecurring charges at the end of the period covered by the computations.

The average annual total return and aggregate total return
information presented for the Funds in the foregoing Tables is based on average
annual total return and aggregate total return, respectively, of Institutional
Shares of the Funds during the periods indicated, as adjusted to reflect the
effect of the maximum sales charge of 2.00% on purchases of Institutional Shares
of the Funds and the maximum payments under the Shareholder Administrative
Services Plans applicable to Institutional and Service Shares and the
distribution expenses pursuant to the 12b-1 Plan applicable to Service Shares.
The sales charge was removed from the Institutional Shares of the Funds as of
October 31, 1998. The average annual total returns and aggregate total returns
do not include fees that may be imposed by institutions upon their customers. If
such fees had been included in the returns reported above, performance of these
Funds would have been lower.

The Funds may also from time to time include in advertisements,
sales literature, communications to shareowners and other materials
("Literature") a total return figure in order to compare more accurately its
performance with other measures of investment return. For example, in comparing
a Fund's total return with data published by Lipper Analytical Services, Inc.,
CDA Investment Technologies, Inc. or Weisenberger Investment Company Service, or
with the performance of an index, the Fund may calculate its total return for
the period of time specified in the advertisement or communication by assuming
the investment of $10,000 in shares and assuming the value on the reinvestment
date. Percentage increases are determined by subtracting the initial value of
the investment from the ending value and by dividing the remainder by the
beginning value. The Fund does not, for these purposes, deduct from the initial
value invested any amount representing sales charges. The Fund will, however,
disclose the maximum sales charge and will also disclose that the performance
data do not reflect sales charges and that inclusion of sale charges would
reduce the performance quoted.

The Funds may also from time to time include discussions or
illustrations of the effects of compounding in Literature. "Compounding" refers
to the fact that, if dividends or

-45-
<PAGE>

other distributions on a Fund investment are reinvested by being paid in
additional Fund shares, any future income or capital appreciation of the Fund
would increase the value, not only of the original Fund investment, but also of
the additional Fund shares received through reinvestment. As a result, the value
of the Fund investment would increase more quickly than if dividends or other
distributions had been paid in cash.

In addition, the Funds may also include in Literature discussions
and/or illustrations of the potential investment goals of a prospective
investor, investment management strategies, techniques, policies or investment
suitability of the Fund (such as value investing, market timing, dollar cost
averaging, asset allocation, constant ratio transfer, automatic accounting
rebalancing, the advantages and disadvantages of investing in tax-deferred and
taxable investments), economic conditions, the relationship between sectors of
the economy and the economy as a whole, various securities markets, the effects
of inflation and historical performance of various asset classes, including but
not limited to, stocks, bonds and Treasury securities. From time to time,
Literature may summarize the substance of information contained in shareholder
reports (including the investment composition of the Fund), as well as the views
of the Advisor as to current market, economy, trade and interest rate trends,
legislative, regulatory and monetary developments, investment strategies and
related matters believed to be of relevance to the Fund. The Fund may also
include in Literature charts, graphs or drawings which compare the investment
objective, return potential, relative stability and/or growth possibilities of
the Fund and/or other mutual funds, or illustrate the potential risks and
rewards of investment in various investment vehicles, including but not limited
to, stocks, bonds, Treasury securities and shares of the Fund and/or other
mutual funds. Literature may include a discussion of certain attributes or
benefits to be derived by an investment in the Fund and/or other mutual funds,
shareholder profiles and hypothetical investor scenarios, timely information on
financial management, tax and retirement planning and investment alternatives to
certificates of deposit and other financial instruments. Such Literature may
include symbols, headlines or other material which highlight or summarize the
information discussed in more detail therein.

APPENDIX A

Commercial Paper Ratings
------------------------

A Standard & Poor's commercial paper rating is a current opinion of the
creditworthiness of an obligor with respect to financial obligations having an
original maturity of no more than 365 days. The following summarizes the rating
categories used by Standard and Poor's for commercial paper:

"A-1" - Obligations are rated in the highest category indicating that
the obligor's capacity to meet its financial commitment on the obligation is
strong. Within this category, certain obligations are designated with a plus
sign (+). This indicates that the obligor's capacity to meet its financial
commitment on these obligations is extremely strong.

"A-2" - Obligations are somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

"A-3" - Obligations exhibit adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.

"B" - Obligations are regarded as having significant speculative
characteristics. The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

"C" - Obligations are currently vulnerable to nonpayment and are
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.

"D" - Obligations are in payment default. The "D" rating category is
used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poor's believes that
such payments will be made during such grace period. The "D" rating will be used
upon the filing of a bankruptcy petition or the taking of a similar action if
payments on an obligation are jeopardized.

Local Currency and Foreign Currency Risks
Country risk considerations are a standard part of Standard & Poor's analysis
for credit ratings on any issuer or issue. Currency of repayment is a key factor
in this analysis. An obligor's capacity to repay foreign obligations may be
lower than its capacity to repay obligations in its local currency due to the
sovereign government's own relatively lower capacity to repay external versus
domestic debt. These sovereign risk considerations are incorporated in the debt
ratings assigned to specific issues. Foreign currency issuer ratings are also
distinguished from local

A-1
<PAGE>

currency issuer ratings to identify those instances where sovereign risks make
them different for the same issuer.

Moody's commercial paper ratings are opinions of the ability of issuers
to repay punctually senior debt obligations not having an original maturity in
excess of one year, unless explicitly noted. The following summarizes the rating
categories used by Moody's for commercial paper:

"Prime-1" - Issuers (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:
leading market positions in well-established industries; high rates of return on
funds employed; conservative capitalization structure with moderate reliance on
debt and ample asset protection; broad margins in earnings coverage of fixed
financial charges and high internal cash generation; and well-established access
to a range of financial markets and assured sources of alternate liquidity.

"Prime-2" - Issuers (or supporting institutions) have a strong ability
for repayment of senior short-term debt obligations. This will normally be
evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

"Prime-3" - Issuers (or supporting institutions) have an acceptable
ability for repayment of senior short-term debt obligations. The effect of
industry characteristics and market compositions may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.

"Not Prime" - Issuers do not fall within any of the Prime rating
categories.

Fitch short-term ratings apply to debt obligations that have time
horizons of less than 12 months for most obligations, or up to three years for
U.S. public finance securities. The following summarizes the rating categories
used by Fitch for short-term obligations:

"F1" - Securities possess the highest credit quality. This designation
indicates the best capacity for timely payment of financial commitments and may
have an added "+" to denote any exceptionally strong credit feature.

"F2" - Securities possess good credit quality. This designation
indicates a satisfactory capacity for timely payment of financial commitments,
but the margin of safety is not as great as in the case of the higher ratings.

"F3" - Securities possess fair credit quality. This designation
indicates that the capacity for timely payment of financial commitments is
adequate; however, near-term adverse changes could result in a reduction to non-
investment grade.

A-2
<PAGE>

"B" - Securities possess speculative credit quality. This designation
indicates minimal capacity for timely payment of financial commitments, plus
vulnerability to near-term adverse changes in financial and economic conditions.

"C" - Securities possess high default risk. This designation indicates
a capacity for meeting financial commitments which is highly uncertain and
solely reliant upon a sustained, favorable business and economic environment.

"D" - Securities are in actual or imminent payment default.

Thomson Financial BankWatch short-term ratings assess the likelihood of
an untimely payment of principal and interest of debt instruments with original
maturities of one year or less. The following summarizes the ratings used by
Thomson Financial BankWatch:

"TBW-1" - This designation represents Thomson Financial BankWatch's
highest category and indicates a very high likelihood that principal and
interest will be paid on a timely basis.

"TBW-2" - This designation represents Thomson Financial BankWatch's
second-highest category and indicates that while the degree of safety regarding
timely repayment of principal and interest is strong, the relative degree of
safety is not as high as for issues rated "TBW-1."

"TBW-3" - This designation represents Thomson Financial BankWatch's
lowest investment-grade category and indicates that while the obligation is more
susceptible to adverse developments (both internal and external) than those with
higher ratings, the capacity to service principal and interest in a timely
fashion is considered adequate.

"TBW-4" - This designation represents Thomson Financial BankWatch's
lowest rating category and indicates that the obligation is regarded as non-
investment grade and therefore speculative.

Corporate and Municipal Long-Term Debt Ratings
----------------------------------------------

The following summarizes the ratings used by Standard & Poor's for
corporate and municipal debt:

"AAA" - An obligation rated "AAA" has the highest rating assigned by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is extremely strong.

"AA" - An obligation rated "AA" differs from the highest rated
obligations only in small degree. The obligor's capacity to meet its financial
commitment on the obligation is very strong.

A-3
<PAGE>

"A" - An obligation rated "A" is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher-rated categories. However, the obligor's capacity to meet
its financial commitment on the obligation is still strong.

"BBB" - An obligation rated "BBB" exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

Obligations rated "BB," "B," "CCC," "CC" and "C" are regarded as having
significant speculative characteristics. "BB" indicates the least degree of
speculation and "C" the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.

"BB" - An obligation rated "BB" is less vulnerable to nonpayment than
other speculative issues. However, it faces major ongoing uncertainties or
exposure to adverse business, financial or economic conditions which could lead
to the obligor's inadequate capacity to meet its financial commitment on the
obligation.

"B" - An obligation rated "B" is more vulnerable to nonpayment than
obligations rated "BB", but the obligor currently has the capacity to meet its
financial commitment on the obligation. Adverse business, financial or economic
conditions will likely impair the obligor's capacity or willingness to meet its
financial commitment on the obligation.

"CCC" - An obligation rated "CCC" is currently vulnerable to
nonpayment, and is dependent upon favorable business, financial and economic
conditions for the obligor to meet its financial commitment on the obligation.
In the event of adverse business, financial, or economic conditions, the obligor
is not likely to have the capacity to meet its financial commitment on the
obligation.

"CC" - An obligation rated "CC" is currently highly vulnerable to
nonpayment.

"C" - The "C" rating may be used to cover a situation where a
bankruptcy petition has been filed or similar action taken, but payments on this
obligation are being continued.

"D" - An obligation rated "D" is in payment default. The "D" rating
category is used when payments on an obligation are not made on the date due
even if the applicable grace period has not expired, unless Standard & Poor's
believes that such payments will be made during such grace period. The "D"
rating also will be used upon the filing of a bankruptcy petition or the taking
of a similar action if payments on an obligation are jeopardized.

- PLUS (+) OR MINUS (-) - The ratings from "AA" through "CCC" may be
modified by the addition of a plus or minus sign to show relative standing
within the major rating categories.
- "r" - The 'r' highlights obligations that Standard & Poor's believes
have significant noncredit risks. Examples of such obligations are securities
with principal or interest return indexed to equities, commodities, or
currencies; certain swaps and options; and interest-only and

A-4
<PAGE>

principal-only mortgage securities. The absence of an 'r' symbol should not be
taken as an indication that an obligation will exhibit no volatility or
variability in total return.

- N.R. Indicates that no rating has been requested, that there is
insufficient information on which to base a rating, or that Standard & Poor's
does not rate a particular obligation as a matter of policy.

The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt:

"Aaa" - Bonds are judged to be of the best quality. They carry the
smallest degree of investment risk and are generally referred to as "gilt
edged." Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.

"Aa" - Bonds are judged to be of high quality by all standards.
Together with the "Aaa" group they comprise what are generally known as high-
grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in "Aaa" securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risk appear somewhat larger than the "Aaa"
securities.

"A" - Bonds possess many favorable investment attributes and are to be
considered as upper-medium-grade obligations. Factors giving security to
principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment sometime in the future.

"Baa" - Bonds are considered as medium-grade obligations, (i.e., they
are neither highly protected nor poorly secured). Interest payments and
principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

"Ba" - Bonds are judged to have speculative elements; their future
cannot be considered as well-assured. Often the protection of interest and
principal payments may be very moderate, and thereby not well safeguarded during
both good and bad times over the future. Uncertainty of position characterizes
bonds in this class.

"B" - Bonds are generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

"Caa " - Bonds are of poor standing. Such issues may be in default or
there may be present elements of danger with respect to principal or interest.

A-5
<PAGE>

"Ca" - Bonds represent obligations which are speculative in a high
degree. Such issues are often in default or have other marked shortcomings.

"C" - Bonds are the lowest rated class of bonds, and issues so rated
can be regarded as having extremely poor prospects of ever attaining any real
investment standing.

Con. (...) - Bonds for which the security depends upon the completion
of some act or the fulfillment of some condition are rated conditionally. These
are bonds secured by (a) earnings of projects under construction, (b) earnings
of projects unseasoned in operating experience, (c) rentals which begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches. Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.

Note: Moody's applies numerical modifiers 1, 2, and 3 in each generic rating
classification from "Aa" through "Caa". The modifier 1 indicates that the
obligation ranks in the higher end of its generic rating category; the modifier
2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the
lower end of its generic rating category.

The following summarizes the ratings used by Fitch for corporate and municipal
bonds:

"AAA" - Bonds considered to be investment grade and of the highest
credit quality. These ratings denote the lowest expectation of credit risk and
are assigned only in case of exceptionally strong capacity for timely payment of
financial commitments. This capacity is highly unlikely to be adversely affected
by foreseeable events.

"AA" - Bonds considered to be investment grade and of very high credit
quality. These ratings denote a very low expectation of credit risk and indicate
very strong capacity for timely payment of financial commitments. This capacity
is not significantly vulnerable to foreseeable events.

"A" - Bonds considered to be investment grade and of high credit
quality. These ratings denote a low expectation of credit risk and indicate
strong capacity for timely payment of financial commitments. This capacity may,
nevertheless, be more vulnerable to changes in circumstances or in economic
conditions than is the case for higher ratings.

"BBB" - Bonds considered to be investment grade and of good credit
quality. These ratings denote that there is currently a low expectation of
credit risk. The capacity for timely payment of financial commitments is
considered adequate, but adverse changes in circumstances and in economic
conditions are more likely to impair this capacity. This is the lowest
investment grade category.

"BB" - Bonds considered to be speculative. These ratings indicate that
there is a possibility of credit risk developing, particularly as the result of
adverse economic change over time; however, business or financial alternatives
may be available to allow financial commitments to be met. Securities rated in
this category are not investment grade.

A-6
<PAGE>

"B" - Bonds are considered highly speculative. These ratings indicate
that significant credit risk is present, but a limited margin of safety remains.
Financial commitments are currently being met; however, capacity for continued
payment is contingent upon a sustained, favorable business and economic
environment.

"CCC", "CC" and "C" - Bonds have high default risk. Default is a real
possibility, and capacity for meeting financial commitments is solely reliant
upon sustained, favorable business or economic developments. "CC" ratings
indicate that default of some kind appears probable, and "C" ratings signal
imminent default.

"DDD," "DD" and "D" - Bonds are in default. The ratings of obligations
in this category are based on their prospects for achieving partial or full
recovery in a reorganization or liquidation of the obligor. While expected
recovery values are highly speculative and cannot be estimated with any
precision, the following serve as general guidelines. "DDD" obligations have the
highest potential for recovery, around 90%-100% of outstanding amounts and
accrued interest. "DD" indicates potential recoveries in the range of 50%-90%,
and "D" the lowest recovery potential, i.e., below 50%.

Entities rated in this category have defaulted on some or all of their
obligations. Entities rated "DDD" have the highest prospect for resumption of
performance or continued operation with or without a formal reorganization
process. Entities rated "DD" and "D" are generally undergoing a formal
reorganization or liquidation process; those rated "DD" are likely to satisfy a
higher portion of their outstanding obligations, while entities rated "D" have a
poor prospect for repaying all obligations.

- To provide more detailed indications of credit quality, the Fitch
ratings from and including "AA" to "CCC" may be modified by the addition of a
plus (+) or minus (-) sign to denote relative standing within these major rating
categories.
- 'NR' indicates the Fitch does not rate the issuer or issue in
question.
- 'Withdrawn': A rating is withdrawn when Fitch deems the amount of
information available to be inadequate for rating purposes, or when an
obligation matures, is called, or refinanced.
- RatingAlert: Ratings are placed on RatingAlert to notify investors
that there is a reasonable probability of a rating change and the likely
direction of such change. These are designated as "Positive", indicating a
potential upgrade, "Negative", for a potential downgrade, or "Evolving", if
ratings may be raised, lowered or maintained. RatingAlert is typically resolved
over a relatively short period.

Thomson Financial BankWatch assesses the likelihood of an untimely
repayment of principal or interest over the term to maturity of long term debt
and preferred stock which are issued by United States commercial banks, thrifts
and non-bank banks; non-United States banks; and broker-dealers. The following
summarizes the rating categories used by Thomson BankWatch for long-term debt
ratings:

A-7
<PAGE>

"AAA" - This designation indicates that the ability to repay principal
and interest on a timely basis is extremely high.

"AA" - This designation indicates a very strong ability to repay
principal and interest on a timely basis, with limited incremental risk compared
to issues rated in the highest category.

"A" - This designation indicates that the ability to repay principal
and interest is strong. Issues rated "A" could be more vulnerable to adverse
developments (both internal and external) than obligations with higher ratings.

"BBB" - This designation represents the lowest investment-grade
category and indicates an acceptable capacity to repay principal and interest.
Issues rated "BBB" are more vulnerable to adverse developments (both internal
and external) than obligations with higher ratings.

"BB," - A rating of BB suggests that the likelihood of default is
considerably less than for lower-rated issues, although there are significant
uncertainties that could affect the ability to adequately service debt
obligations.

"B" - Issues rated B show a higher degree of uncertainty and therefore
greater likelihood of default than higher-rated issues. Adverse developments
could negatively affect the payment of interest and principal on a timely basis.

"CCC" - Issues rated CCC clearly have a high likelihood of default,
with little capacity to address further adverse changes in financial
circumstances.

"CC" - This rating is applied to issues that are subordinate to other
obligations rated CCC and are afforded less protection in the event of
bankruptcy or reorganization.

"D" - This designation indicates that the long-term debt is in default.

PLUS (+) OR MINUS (-) - The ratings from "AAA" through "CC" may include
a plus or minus sign designation which indicates where within the respective
category the issue is placed.

Municipal Note Ratings

A Standard and Poor's note rating reflects the liquidity factors and
market access risks unique to notes due in three years or less. The following
summarizes the ratings used by Standard & Poor's for municipal notes:

A-8
<PAGE>

"SP-1" - The issuers of these municipal notes exhibit a strong capacity
to pay principal and interest. Those issues determined to possess a very strong
capacity to pay debt service are given a plus (+) designation.

"SP-2" - The issuers of these municipal notes exhibit satisfactory
capacity to pay principal and interest, with some vulnerability to adverse
financial and economic changes over the term of the notes.

"SP-3" - The issuers of these municipal notes exhibit speculative
capacity to pay principal and interest.

Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade ("VMIG"). Such
ratings recognize the differences between short-term credit risk and long-term
risk. The following summarizes the ratings by Moody's Investors Service, Inc.
for short-term notes:

"MIG-1"/"VMIG-1" - This designation denotes best quality. There is
present strong protection by established cash flows, superior liquidity support
or demonstrated broad-based access to the market for refinancing.

"MIG-2"/"VMIG-2" - This designation denotes high quality. Margins of
protection are ample although not so large as in the preceding group.

"MIG-3"/"VMIG-3" - This designation denotes favorable quality, with all
security elements accounted for but lacking the undeniable strength of the
preceding grades. Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.

"MIG-4"/"VMIG-4" - This designation denotes adequate quality.
Protection commonly regarded as required of an investment security is present
and although not distinctly or predominantly speculative, there is specific
risk.

"SG" - This designation denotes speculative quality. Debt instruments
in this category lack margins of protection.

Fitch uses the short-term ratings described under Commercial Paper
Ratings for municipal notes.

The Growth, MidCap, International Equity, Balanced, Bond,
National Tax-Free Intermediate Bond and Missouri Tax-Free Intermediate Bond
Funds may enter into futures contracts and options. Such transactions are
described in this Appendix.

I. Interest Rate Futures Contracts.
-------------------------------

Use of Interest Rate Futures Contracts. Bond prices are
--------------------------------------
established in both the cash market and the futures market. In the cash market,
bonds are purchased and sold with payment for the full purchase price of the
bond being made in cash, generally within five business days after the trade. In
the futures market, only a contract is made to purchase or sell a bond in the
future for a set price on a certain date. Historically, the prices for bonds
established in the futures markets have tended to move generally in the
aggregate in concert with the cash market prices and have maintained fairly
predictable relationships. Accordingly, the Funds may use interest rate futures
contracts as a defense, or hedge, against anticipated interest rate changes and
not for speculation. As described below, this would include the use of futures
contract sales to protect against expected increases in interest rates and
futures contract purchases to offset the impact of interest rate declines.

A Fund presently could accomplish a similar result to that
which it hopes to achieve through the use of futures contracts by selling bonds
with long maturities and investing in bonds with short maturities when interest
rates are expected to increase, or conversely, selling short-term bonds and
investing in long-term bonds when interest rates are expected to decline.
However, because of the liquidity that is often available in the futures market
the protection is more likely to be achieved, perhaps at a lower cost and
without changing the rate of interest being earned by the Fund, by using futures
contracts.

Description of Interest Rate Futures Contracts. An interest
----------------------------------------------
rate futures contract sale would create an obligation by a Fund, as seller, to
deliver the specific type of financial instrument called for in the contract at
a specific future time for a specified price. A futures contract purchase would
create an obligation by a Fund, as purchaser, to take delivery of the specific
type of financial instrument at a specific future time at a specific price. The
specific securities delivered or taken, respectively, at settlement date, would
not be determined until at or near that date. The determination would be in
accordance with the rules of the exchange on which the futures contract sale or
purchase was made.

B-1
<PAGE>

Although interest rate futures contracts by their terms call
for actual delivery or acceptance of securities, in most cases the contracts are
closed out before the settlement date without the making or taking of delivery
of securities. Closing out a futures contract sale is effected by the Fund
entering into a futures contract purchase for the same aggregate amount of the
specific type of financial instrument and the same delivery date. If the price
of the sale exceeds the price of the offsetting purchase, the Fund is
immediately paid the difference and thus realizes a gain. If the offsetting
purchase price exceeds the sale price, the Fund pays the difference and realizes
a loss. Similarly, the closing out of a futures contract purchase is effected by
the Fund entering into a futures contract sale. If the offsetting sale price
exceeds the purchase price, a Fund realizes a gain, and if the purchase price
exceeds the offsetting sale price, the Fund realizes a loss.

Interest rate futures contracts are traded in an auction
environment on the floors of several exchanges -- principally, the Chicago Board
of Trade and the Chicago Mercantile Exchange and the New York Futures Exchange.
The Funds would deal only in standardized contracts on recognized exchanges.
Each exchange guarantees performance under contract provisions through a
clearing corporation, a nonprofit organization managed by the exchange
membership.

A public market now exists in futures contracts covering
various financial instruments including long-term Treasury Bonds and Notes;
Government National Mortgage Association (GNMA) modified pass-through mortgage-
backed securities, three-month Treasury Bills; and ninety-day commercial paper.
A Fund may trade in any futures contract for which there exists a public market,
including, without limitation, the foregoing instruments.

II. Stock Index Futures Contracts.
-----------------------------

General. A stock index assigns relative values to the stocks
-------
included in the index and the index fluctuates with changes in the market values
of the stocks included. Some stock index futures contracts are based on broad
market indexes, such as the Standard & Poor's 500 or the New York Stock Exchange
Composite Index. In contrast, certain exchanges offer futures contracts on
narrower market indexes, such as the Standard & Poor's 100 or indexes based on
an industry or market segment, such as oil and gas stocks. Futures contracts are
traded on organized exchanges regulated by the Commodity Futures Trading
Commission. Transactions on such exchanges are cleared through a clearing
corporation, which guarantees the performance of the parties to each contract.

A Fund will sell index futures contracts in order to offset a
decrease in market value of its portfolio securities that might otherwise result
from a market decline. A Fund may do so either to hedge the value of its
portfolio as a whole, or to protect against declines, occurring prior to sales
of securities, in the value of the securities to be sold. Conversely, a Fund
will purchase index futures contracts in anticipation of purchases of
securities. In a substantial majority of these transactions, a Fund will
purchase such securities upon termination of the long futures position, but a
long futures position may be terminated without a corresponding purchase of
securities.

B-2
<PAGE>

In addition, a Fund may utilize stock index futures contracts
in anticipation of changes in the composition of its holdings. For example, in
the event that a Fund expects to narrow the range of industry groups represented
in its holdings it may, prior to making purchases of the actual securities,
establish a long futures position based on a more restricted index, such as an
index comprised of securities of a particular industry group. A Fund may also
sell futures contracts in connection with this strategy, in order to protect
against the possibility that the value of the securities to be sold as part of
the restructuring of its portfolio will decline prior to the time of sale.

III. Futures Contracts on Foreign Currencies.
---------------------------------------

A futures contract on foreign currency creates a binding
obligation on one party to deliver, and a corresponding obligation on another
party to accept delivery of, a stated quantity of a foreign currency, for an
amount fixed in U.S. dollars. Foreign currency futures may be used by a Fund to
hedge against exposure to fluctuations in exchange rates between the U.S. dollar
and other currencies arising from multinational transactions.

IV. Margin Payments.
---------------

Unlike when a Fund purchases or sells a security, no price is
paid or received by a Fund upon the purchase or sale of a futures contract.
Initially, a Fund will be required to deposit with the broker or in a segregated
account with a Fund's custodian an amount of cash or cash equivalents, the value
of which may vary but is generally equal to 10% or less of the value of the
contract. This amount is known as initial margin. The nature of initial margin
in futures transactions is different from that of margin in security
transactions in that futures contract margin does not involve the borrowing of
funds by the customer to finance the transactions. Rather, the initial margin is
in the nature of a performance bond or good faith deposit on the contract which
is returned to the Fund upon termination of the futures contract assuming all
contractual obligations have been satisfied. Subsequent payments, called
variation margin, to and from the broker, will be made on a daily basis as the
price of the underlying instrument fluctuates making the long and short
positions in the futures contract more or less valuable, a process known as
"marking-to-market." For example, when a Fund has purchased a futures contract
and the price of the contract has risen in response to a rise in the underlying
instruments, that position will have increased in value a Fund will be entitled
to receive from the broker a variation margin payment equal to that increase in
value. Conversely, where a Fund has purchased a futures contract and the price
of the future contract has declined in response to a decrease in the underlying
instruments, the position would be less valuable and a Fund would be required to
make a variation margin payment to the broker. At any time prior to expiration
of the futures contract, The Commerce Funds may elect to close the position by
taking an opposite position, subject to the availability of a secondary market,
which will operate to terminate a Fund's position in the futures contract. A
final determination of variation margin is then made, additional cash is
required to be paid by or released to a Fund, and a Fund realizes a loss or
gain.

B-3
<PAGE>

V. Risks of Transactions in Futures Contracts.
------------------------------------------

There are several risks in connection with the use of futures
by a Fund as a hedging device. One risk arises because of the imperfect
correlation between movements in the price of the futures and movements in the
price of the securities which are the subject of the hedge. The price of the
future may move more than or less than the price of the securities being hedged.
If the price of the futures moves less than the price of the securities which
are the subject of the hedge, the hedge will not be fully effective but, if the
price of the securities being hedged has moved in an unfavorable direction, the
Fund would be in a better position than if it had not hedged at all. If the
price of the securities being hedged has moved in a favorable direction, this
advantage will be partially offset by the loss on the future. If the price of
the future moves more than the price of the hedged securities, a Fund involved
will experience either a loss or gain on the future which will not be completely
offset by movements in the price of the securities which are the subject of the
hedge. To compensate for the imperfect correlation of movements in the price of
securities being hedged and movements in the price of futures contracts, a Fund
may buy or sell futures contracts in a greater dollar amount than the dollar
amount of securities being hedged if the volatility over a particular time
period of the prices of such securities has been greater than the volatility
over such time period of the future, or if otherwise deemed to be appropriate by
The Commerce Funds. Conversely, a Fund may buy or sell fewer futures contracts
if the volatility over a particular time period of the prices of the securities
being hedged is less than the volatility over such time period of the future
contract being used, or if otherwise deemed to be appropriate by The Commerce
Funds. It is also possible that, where a Fund has sold futures to hedge its
portfolio against a decline in the market, the market may advance and the value
of securities held in a Fund may decline. If this occurred, a Fund would lose
money on the future and also experience a decline in value in its portfolio
securities.

Where futures are purchased to hedge against a possible
increase in the price of securities or a currency before a Fund is able to
invest its cash (or cash equivalents) in securities (or options) in an orderly
fashion, it is possible that the market may decline instead; if a Fund then
concludes not to invest in securities or options at that time because of concern
as to possible further market decline or for other reasons, a Fund will realize
a loss on the futures contract that is not offset by a reduction in the price of
securities to be purchased.

In addition to the possibility that there may be an imperfect
correlation, or no correlation at all, between movements in the futures and the
securities being hedged, the price of futures may not correlate perfectly with
movement in the cash market due to certain market distortions. Rather than
meeting additional margin deposit requirements, investors may close futures
contracts through off-setting transactions which could distort the normal
relationship between the cash and futures markets. Second, with respect to
financial futures contracts, the liquidity of the futures market depends on
participants entering into off-setting transactions rather than making or taking
delivery. To the extent participants decide to make or take delivery, liquidity
in the futures market could be reduced thus producing distortions. Third, from
the point of view of speculators, the deposit requirements in the futures market
are less onerous than margin requirements in the securities market. Therefore,
increased participation by speculators

B-4
<PAGE>

in the futures market may also cause temporary price distortions. Due to the
possibility of price distortion in the futures market, and because of the
imperfect correlation between the movements in the cash market and movements in
the price of futures, a correct forecast of general market trends or interest
rate movements by The Commerce Funds may still not result in a successful
hedging transaction over a short time frame.

Positions in futures may be closed out only on an exchange or
board of trade which provides a secondary market for such futures. Although the
Funds intend to purchase or sell futures only on exchanges or boards of trade
where there appear to be active secondary markets, there is no assurance that a
liquid secondary market on any exchange or board of trade will exist for any
particular contract or at any particular time. In such event, it may not be
possible to close a futures investment position, and in the event of adverse
price movements, the Funds would continue to be required to make daily cash
payments of variation margin. However, in the event futures contracts have been
used to hedge portfolio securities, such securities will not be sold until the
futures contract can be terminated. In such circumstances, an increase in the
price of the securities, if any, may partially or completely offset losses on
the futures contract. However, as described above, there is no guarantee that
the price of the securities will in fact correlate with the price movements in
the futures contract and thus provide an offset on a futures contract.

Further, it should be noted that the liquidity of a secondary
market in a futures contract may be adversely affected by "daily price
fluctuation limits" established by commodity exchanges which limit the amount of
fluctuation in a futures contract price during a single trading day. Once the
daily limit has been reached in the contract, no trades may be entered into at a
price beyond the limit, thus preventing the liquidation of open futures
positions. The trading of futures contracts is also subject to the risk of
trading halts, suspensions, exchange or clearing house equipment failures,
government intervention, insolvency of a brokerage firm or clearing house or
other disruptions of normal trading activity, which could at times make it
difficult or impossible to liquidate existing positions or to recover excess
variation margin payments.

Successful use of futures by the Funds is also subject to The
Commerce Funds' ability to predict correctly movements in the direction of the
market. For example, if a particular Fund has hedged against the possibility of
a decline in the market adversely affecting securities held in its Portfolio and
securities prices increase instead, a Fund will lose part or all of the benefit
to the increased value of its securities which it has hedged because it will
have offsetting losses in its futures positions. In addition, in such
situations, if a Fund has insufficient cash, it may have to sell securities to
meet daily variation margin requirements. Such sales of securities may be, but
will not necessarily be, at increased prices which reflect the rising market. A
Fund may have to sell securities at a time when it may be disadvantageous to do
so.

VI. Options on Futures Contracts
----------------------------

The Funds may purchase options on the futures contracts
described above. A futures option gives the holder, in return for the premium
paid, the right to buy (call) from or sell (put) to the writer of the option a
futures contract at a specified price at any time during the

B-5
<PAGE>

period of the option. Upon exercise, the writer of the option is obligated to
pay the difference between the cash value of the futures contract and the
exercise price. Like the buyer or seller of a futures contract, the holder, or
writer, of an option has the right to terminate its position prior to the
scheduled expiration of the option by selling, or purchasing, an option of the
same series, at which time the person entering into the closing transaction will
realize a gain or loss.

Investments in futures options involve some of the same
considerations that are involved in connection with investments in futures
contracts (for example, the existence of a liquid secondary market). In
addition, the purchase or sale of an option also entails the risk that changes
in the value of the underlying futures contract will not be fully reflected in
the value of the option purchased. Depending on the pricing of the option
compared to either the futures contract upon which it is based, or upon the
price of the securities being hedged, an option may or may not be less risky
than ownership of the futures contract or such securities. In general, the
market prices of options can be expected to be more volatile than the market
prices on the underlying futures contract. Compared to the purchase or sale of
futures contracts, however, the purchase of call or put options on futures
contracts may frequently involve less potential risk to the Fund because the
maximum amount at risk is the premium paid for the options (plus transaction
costs). The writing of an option on a futures contract involves risks similar to
those risks relating to the sale of futures contracts. Although permitted by
their fundamental investment policies, the Funds do not currently intend to
write futures options during the current fiscal year, and will not do so in the
future absent any necessary regulatory approvals.

VII. Accounting and Tax Treatment.
----------------------------

Accounting for futures contracts and options will be in
accordance with generally accepted accounting principles.

Generally, futures contracts held by the Funds at the close of
the Funds' taxable year will be treated for federal income tax purposes as sold
for their fair market value on the last business day of such year, a process
known as "mark-to-market." Forty percent of any gain or loss resulting from such
constructive sale will be treated as short-term capital gain or loss and sixty
percent of such gain or loss will be treated as long-term capital gain or loss
without regard to the length of time a Fund holds the futures contract ("the 40-
60 rule"). The amount of any capital gain or loss actually realized by a Fund in
a subsequent sale or other disposition of those futures contracts will be
adjusted to reflect any capital gain or loss taken into account by a Fund in a
prior year as a result of the constructive sale of the contracts. With respect
to futures contracts to sell, which will be regarded as parts of a "mixed
straddle" because their values fluctuate inversely to the values of specific
securities held by a Fund, losses as to such contracts to sell will be subject
to certain loss deferral rules which limit the amount of loss currently
deductible on either part of the straddle to the amount thereof which exceeds
the unrecognized gain (if any) with respect to the other part of the straddle,
and to certain wash sales regulations. Under short sales rules, which will also
be applicable, the holding period of the securities forming part of the straddle
will (if they have not been held for the long-term holding period) be deemed not
to begin prior to termination of the straddle. With respect to certain futures
contracts, deductions for interest and carrying charges will not be allowed.
Notwithstanding the

B-6
<PAGE>

rules described above, with respect to futures contracts to sell which are
properly identified as such, a Fund may make an election which will exempt (in
whole or in part) those identified futures contracts from being treated for
federal income tax purposes as sold on the last business day of a Fund's taxable
year, but gains and losses will be subject to such short sales, wash sales, loss
deferral rules and the requirement to capitalize interest and carrying charges.
Under temporary regulations, a Fund would be allowed (in lieu of the foregoing)
to elect either (1) to offset gains or losses from portions which are part of a
mixed straddle by separately identifying each mixed straddle to which such
treatment applies, or (2) to establish a mixed straddle account for which gains
and losses would be recognized and offset on a periodic basis during the taxable
year. Under either election, the 40-60 rule will apply to the net gain or loss
attributable to the futures contracts, but in the case of a mixed straddle
account election, no more than 50% of any net gain may be treated as long-term
and no more than 40% of any net loss may be treated as short-term. Opinions on
futures contracts generally receive federal tax treatment similar to that
described above.

Certain foreign currency contracts entered into by the Funds
may be subject to the "mark-to-market" process. If the Fund makes a Capital
Asset Election with respect to such contracts, the contracts will be subject to
the 40-60 rule, described above. Otherwise, such gain or loss will be treated as
100% ordinary gain or loss. To receive such federal income tax treatment, a
foreign currency contract must meet the following conditions: (1) the contract
must require delivery of a foreign currency of a type in which regulated futures
contracts are traded or upon which the settlement value of the contract depends;
(2) the contract must be entered into at arm's length at a price determined by
reference to the price in the interbank market; and (3) the contract must be
traded in the interbank market. The Treasury Department as has broad authority
to issue regulations under the provisions respecting foreign currency contracts.
As of the date of this Statement of Additional Information, the Treasury has not
issued any such regulations. Foreign currency contracts entered into by a Fund
may result in the creation of one or more straddles for federal income tax
purposes, in which case certain loss deferral, short sales, and wash sales rules
and the requirement to capitalize interest and carrying charges may apply.

Some investments may be subject to special rules which govern
the federal income tax treatment of certain transactions denominated in terms of
a currency other than the U.S. dollar or determined by reference to the value of
one or more currencies other than the U.S. dollar. The types of transactions
covered by the special rules include the following: (i) the acquisition of, or
becoming the obligor under, a bond or other debt instrument (including, to the
extent provided in Treasury regulations, preferred stock); (ii) the accruing of
certain trade receivables and payables; and (iii) the entering into or
acquisition of any forward contract, futures contract, option and similar
financial instrument. However, regulated futures contracts and non-equity
options are generally not subject to the special currency rules if they are or
would be treated as sold for their fair market value at year-end under the
"mark-to-market" rules, unless an election is made to have such currency rules
apply. The disposition of a currency other than the U.S. dollar by a U.S.
taxpayer is also treated as a transaction subject to the special currency rules.
With respect to transactions covered by the special rules, foreign currency gain
or loss is calculated separately from any gain or loss on the underlying
transaction and is normally taxable as ordinary gain or loss. A taxpayer may
elect to treat as capital gain or loss foreign currency

B-7
<PAGE>

gain or loss arising from certain identified forward contracts, futures
contracts and options that are capital assets in the hands of the taxpayer and
which are not part of a straddle. In accordance with Treasury regulations,
certain transactions subject to the special currency rules that are part of a
"section 988 hedging transaction" (as defined in the Code and the Treasury
regulations) will be integrated and treated as a single transaction or otherwise
treated consistently for purposes of the Code. "Section 988 hedging
transactions" are not subject to the mark-to-market or loss deferral rules under
the Code. It is anticipated that some of the non-U.S. dollar denominated
investments and foreign currency contracts that a Fund may make or may ender
into will be subject to the special currency rules described above. Gain or loss
attributable to the foreign currency component of transactions engaged in by the
Funds which are not subject to special currency rules (such as foreign equity
investments other than certain preferred stocks) will be treated as capital gain
or loss and will not be segregated from the gain or loss on the underlying
transaction.

Under the federal income tax provisions applicable to
regulated investment companies, less than 30% of a company's gross income must
be derived from gains realized on the sale or other disposition of securities
held for less than three months. With respect to futures contracts and other
financial instruments subject to the "mark-to-market" rules, the Internal
Revenue Service has ruled in private letter rulings that a gain realized from
such a futures contract or financial instrument will be treated as being derived
from a security held for three months or more (regardless of the actual period
for which the contract or instrument is held) if the gain arises as a result of
a constructive sale under the "mark-to-market" rules, and will be treated as
being derived from a security held for less than three months only if the
contract or instrument is terminated (or transferred) during the taxable year
(other than by reason of the mark-to-market rules) and less than three months
have elapsed between the date the contract or instrument is acquired and the
termination date. In determining whether the 30% test is met for a taxable year,
increases and decreases in the value of the Funds' futures contracts and other
investments that qualify as part of a "designated hedge," as defined in the
Code, may be netted.

Item 25. INDEMNIFICATION
---------------

Section IV of the Administration Agreement and Section XIII of the
Distribution Agreement between the Registrant and Goldman, Sachs & Co.
("Goldman") provides for indemnification of Goldman in connection with certain
claims and liabilities to which Goldman, in its capacity as Registrant's
Administrator and Distributor, may be subject. Copies of the Administration
Agreement and Distribution Agreement are incorporated herein by reference as
Exhibits 23(e) and (h), respectively.

Registrant has obtained from a major insurance carrier a trustees' and
officers' liability policy covering certain types of errors and omissions.

In addition, Section 10.2 of Registrant's Trust Instrument, a copy of
which is incorporated herein by reference as Exhibit 23(a), provides for
indemnification of the Trustees and officers as follows:

Section 10.2 Indemnification. The Trust shall indemnify each of its
---------------
Trustees against all liabilities and expenses (including amounts paid
in satisfaction of judgments, in compromise, as fines and penalties,
and as counsel fees) reasonably incurred by him in connection with the
defense or disposition of any action, suit or other proceeding,
whether civil or criminal, in which he may be involved or with which
he may be threatened, while as a Trustee or thereafter, by reason of
his being or having been such a Trustee except with respect to any
------
matter as to which he shall have been adjudicated to have acted in bad
faith, willful misfeasance, gross negligence or reckless disregard of
his duties, provided that as to any matter disposed of by a compromise
--------
payment by such person, pursuant to a consent decree or otherwise, no
indemnification either for said payment or for any other expenses
shall be provided unless the Trust shall have received a written
opinion from independent legal counsel approved by the Trustees to the
effect that if either the matter or willful misfeasance, gross
negligence or reckless disregard of duty, or the matter of bad faith
had been adjudicated, it would in the opinion of such counsel have
been adjudicated in favor of such person. The rights accruing to any
person under these provisions shall not exclude any other right to
which he may be lawfully entitled, provided that no person may satisfy
--------
any right of indemnity or reimbursement hereunder except out of the
property of the Trust. The Trustees may make advance payments in
connection with the indemnification under this Section 10.2, provided
--------
that the indemnified person shall have given a written undertaking to
reimburse the Trust in the event it is subsequently determined that he
is not entitled to such indemnification.

The Trust shall indemnify officers, and shall have the power to
indemnify representatives and employees of the Trust, to the same
extent that Trustees are entitled to indemnification pursuant to this
Section 10.2.

Section 10.3 of Registrant's Trust Instrument provides for
indemnification of shareholders as follows:

Section 10.3 Shareholders. In case any Shareholder or former
------------
Shareholder of any Series shall be held to be personally liable solely
by reason of his being or having been a Shareholder of such Series and
not because of his acts or omissions or for some other reason, the
Shareholder or former Shareholder (or his heirs, executors,
administrators or other legal representatives, or in the case of a
corporation or other entity, its corporate or other general successor)
shall be entitled out of the assets belonging to the applicable Series
to be held harmless from and indemnified against all loss and expense
arising from such liability. The Trust, on behalf of the affected
Series, shall, upon request by the Shareholder, assume the defense of
any claim made against the Shareholder for any act or obligation of
the Series and satisfy any judgment thereon from the assets of the
Series.

Insofar as indemnification for liability arising under the Securities
Act of 1933 may be permitted to Trustees, officers and controlling persons of
Registrant pursuant to the foregoing provisions, or otherwise, Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by Registrant of expenses incurred or
paid by a Trustee, officer or controlling person of 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,
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.
