RISK/RETURN SUMMARY AND FUND EXPENSES
The following is a summary of certain key information about the Fund. You will
find additional information about the Fund, including a detailed description of
the risks of an investment in the Fund, after this summary.
RISK/RETURN SUMMARY OF THE LYON STREET INSTITUTIONAL MONEY MARKET FUND
Investment Objectives The Fund seeks current income from short-term
securities while preserving capital and main-
taining liquidity.
Principal Investment The Fund is a money market fund that seeks to
Strategies maintain a stable net asset value of $1.00 per
share. The Fund invests in a broad range of
short-term instruments including commercial pa-
per, short-term corporate obligations and
short-term obligations issued or guaranteed by
the United States Government, its agencies or
instrumentalities.
Principal Investment Risks The Fund's performance per share will change
daily based on many factors, including, the
quality of the instruments in the Fund's in-
vestment portfolio, national and international
economic conditions and general market condi-
tions. Changes in the interest rate will affect
the yield or value of the Fund's investments in
debt securities.
. An investment in the Fund is not a deposit in
a bank and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or
any other govern- ment agency.
. Although the Fund seeks to preserve the value
of your investment at $1.00 per share, it is
possible to lose money by investing in the
Fund.
. If an issuer fails to pay interest or repay
principal, the value of your investment could
decline.
. Because the Fund invests in short-term secu-
rities, a decline in interest rates will af-
fect the Fund's yield as these securities ma-
ture or are sold and the Fund purchases new
short-term securities with a lower yield.
. Foreign investments may be riskier than U.S.
investments because of unstable international
political and economic conditions, foreign
controls on investment and currency exchange,
withholding taxes, a lack of adequate company
information, and lack of government regula-
tion.
. There can be no assurance that the investment
objective of the Fund will be achieved.

any time.

INVESTMENT OBJECTIVES, STRATEGIES AND RISKS
Investment Objectives, Policies and Strategies
The Fund's investment objective is to seek current income from
short-term securities while preserving capital and maintaining
liquidity. As a money market fund, the Fund must meet the
requirements of the Securities and Exchange Commission's Rule
2a-7. This rule imposes strict requirements on the investment
quality, maturity, and diversification of the Fund's
investments. Under Rule 2a-7, the Fund's investments must have
a remaining maturity of no more than 397 days, and its
investments must maintain an average weighted maturity that
does not exceed 90 days.
With respect to substantially all of its securities, the Fund
will only buy a security if it has the highest short-term
rating from at least two nationally recognized statistical
rating organizations, such as Standard & Poor's Ratings Group
or Moody's Investors Service, Inc., or only one such rating if
only one organization has rated the instrument. If the money
market instrument is not rated, the Adviser must determine that
it is of comparable quality to eligible rated instruments. In
addition, the Fund considers an investment's projected rate of
return and whether the investment meets the requirements of
Rule 2a-7.
The Statement of Additional Information has more detailed
information about the investment policies and strategies of the
Fund.
Investment Risks
The Fund's primary risks are interest rate risk and credit
risk. Because the Fund invests in short-term securities, a
decline in interest rates will affect the Fund's yield as these
securities mature or are sold and the Fund purchases new short-
term securities with a lower yield. Generally, an increase in
interest rates causes the value of a debt instrument to
decrease. The change in value for shorter-term securities is
usually smaller than for securities with longer maturities.
Because the Fund invests in securities with short maturities
and seeks to maintain a stable net asset value of $1.00 per
share, it is possible, though unlikely, that an increase in
interest rates would change the value of your investment.
Credit risk is the possibility that a security's credit rating
will be downgraded or that the issuer of the security will
default (fail to make scheduled interest and principal
payments). The Fund invests in highly-rated securities to
minimize credit risk. Under Rule 2a-7, 95% of a money market
fund's holdings must be rated in the highest credit category
(e.g., A-1 or A-1+) and the remaining 5% must be rated no lower
than the second highest credit category.
The Fund's investments in U.S. dollar-denominated obligations
of foreign branches of U.S. banks and U.S. branches of foreign
banks may be subject to foreign risk. Foreign investments
subject the Fund to investment risks different from those
associated with domestic investments. Foreign securities
issuers are usually subject to less regulation than U.S.
issuers. Reporting, accounting, and auditing standards of
foreign countries are less stringent, in some cases
significantly, than U.S. standards. Foreign risk includes
nationalization, expropriation or confiscatory taxation,
currency blockage, political changes or diplomatic developments
that could adversely affect the Fund's investments.
The Fund also is subject to management risk because it is an
actively managed portfolio. The Fund's Adviser uses its
investment techniques and risk analyses in making investment
decisions for the Fund, but there is no guarantee that its
techniques will produce the intended result.

<PAGE>
INVESTMENT OBJECTIVES, STRATEGIES AND RISKS
There can be no assurance that the investment objective of the
Fund will be achieved. In addition, the Fund's investment
policies, as well as the relatively short maturity of
obligations purchased by the Fund, may result in frequent
changes in the Fund's portfolio, which may give rise to taxable
gains.
Year 2000 Risks
Like other funds and business organizations around the world,
the Fund could be adversely affected if the computer systems
used by the Adviser and the Fund's other service providers do
not properly process and calculate date-related information for
the year 2000 and beyond. In addition, year 2000 issues may
adversely affect companies in which the Fund invests where, for
example, such companies incur substantial costs to address year
2000 issues or suffer losses caused by the failure to
adequately or timely do so.
The Fund has been assured that the Adviser and other service
providers have developed and are implementing clearly defined
and documented plans intended to minimize risks to services
critical to the Fund's operations associated with year 2000
issues. The Adviser and the Fund's service providers have
likewise sought assurances from their respective vendors and
suppliers that such entities are addressing any year 2000
issues.
Based on the information currently available, the Fund does not
anticipate any material adverse impact on the business
operations or financial conditions of the Adviser, the Fund's
service providers or the Fund due to year 2000 issues. However,
the ultimate costs or consequences of incomplete or untimely
resolution of year 2000 issues by the Adviser or the Fund's
service providers may not be fully evident as of the date of
this prospectus.

GENERAL POLICIES ON SELLING SHARES
- --------------------------------------------------------------------------------
General Redemption
Information During periods of unusual market activity it may
be difficult to reach the Fund by telephone. In
such cases, shareholders should follow the
procedures for redeeming by mail or through a
broker. Neither the Fund nor any of its service
providers will be liable for following telephone
instructions reasonably believed to be genuine
unless it acts with willful misfeasance, bad
faith or gross negligence. In this regard, the
Fund and its transfer agent will employ
procedures designed to provide reasonable
assurance that instructions by telephone are
genuine. Such procedures will include the
requirement that personal identification be
provided before accepting a telephone
redemption.
The Fund reserves the right to redeem an account
if its value falls below $100,000 as a result of
redemptions or exchanges (but not as a result of
a decline in net asset value). A shareholder
will be notified in writing and allowed 60 days
to increase the value of the account to the
minimum investment level.
Payment of Redemption You can generally expect to receive redemption
Proceeds proceeds within seven days of receipt of a
request. Payment for shares may be delayed under
extraordinary circumstances or as permitted by
the SEC in order to protect remaining
shareholders.
Redemption in The Fund reserves the right to make payment in
Kind securities rather than cash, known as a
"redemption in kind." This could occur under
extraordinary circumstances, such as a very
large redemption that could affect Fund
operations (for example, more than 1% of the
Fund's net assets). If the Fund deems it
advisable for the benefit of all shareholders, a
redemption in kind will consist of securities
equal in market value to your shares. When you
convert these securities to cash, you will pay
brokerage charges.
IMPORTANT INFORMATION REGARDING STOCK
CERTIFICATES AND REDEMPTION NOTICES. Signatures
on all redemption notices and stock certificates
must be guaranteed by a U.S. stock exchange mem-
ber, a U.S. commercial bank or trust company or
other entity approved by the Fund, unless the
amount redeemed is less than $50,000 and the ac-
count address has been the same for at least 90
days. The Fund can change the above requirements
or require additional documents at any time.

value next determined after the exchange request is received in good order by
the Fund. Be sure to read carefully the prospectus of any fund into which you

five exchanges between investment portfolios offered by the Kent Funds in a
year, or more than three exchanges in a calendar quarter. Although unlikely,
the Kent Funds may reject any exchanges or change or terminate rights to ex-
change shares. The exchange privilege is available only in states where shares
of the new fund may be sold.

SHAREHOLDER INFORMATION
DIVIDENDS, DISTRIBUTIONS AND TAXES
Any income the Fund receives is paid out, less expenses, in the form of
dividends to its shareholders. The Fund declares dividends from net investment
income on every business day. Dividends on the Fund are paid monthly. Capital
gains, if any, for the Fund are distributed at least annually.
The Fund contemplates declaring as dividends each year all or substantially all
of its taxable income, including its net capital gain (the excess of long-term
capital gain over short-term capital loss). You will be subject to income tax
on these distributions regardless of whether they are paid in cash or
reinvested in additional shares. Distributions attributable to the net capital
gain of the Fund will be taxable to you as long-term capital gain, regardless
of how long you have held your shares. Other Fund distributions will generally
be taxable as ordinary income.
The Fund expects the dividends will primarily consist of ordinary income or, if
any, short-term capital gains as opposed to long-term capital gains.
You should note that if you purchase shares just prior to a capital gain
distribution, the purchase price will reflect the amount of the upcoming
distribution, but you will be taxable on the entire amount of the distribution
received, even though, as an economic matter, the distribution simply
constitutes a return of capital. This is known as "buying into a dividend."
The one major exception to these tax principles 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.
Taxable dividends paid in January may be taxable as if they had been paid the
previous December. Each year you will receive in the mail federal tax
information on distributions paid by the Fund.
Generally, shareholders may also be subject to state and local taxes on
distributions and redemptions. State income taxes may not apply, however, to
the portions of the Fund's distributions, if any, that are attributable to
interest on U.S. Government securities or on securities of a particular state.
