INVESTMENT OBJECTIVES    Long-term capital appreciation with current income as
                         a secondary objective.     
   
PRINCIPAL INVESTMENT     To achieve its objectives, the Fund invests substan- 
STRATEGIES               tially all of its assets in common stock of companies
                         that make up the S&P 500. Lyon Street will generally
                         try to match the industry composition of the S&P 500;
                         however, the Fund may be invested in the S&P 500 com-
                         panies in different proportions. The Fund will try to
                         achieve a close correlation between the performance
                         that it generates and that of the S&P 500. Several
                         factors may affect the Fund's ability to exactly
                         track the S&P 500's performance, including the timing
                         of purchases and redemptions, changes in securities
                         markets and in the size of the Fund.

INVESTMENT OBJECTIVE       Long-term capital appreciation.
                         
PRINCIPAL INVESTMENT       The Fund normally invests at least 65% of its total
STRATEGIES                 assets in the common and preferred stocks of compa-
                           nies located in at least three countries in Europe,
                           Australia and the Far East.     
                              
                           Lyon Street considers a country's Gross Domestic
                           Product and market capitalization relative to other
                           countries when determining region and country alloca-
                           tions among Europe, Australia and the Pacific Rim.
                           Allocation among companies is determined based on a
                           stock's market capitalization and industry attrac-
                           tiveness. Stocks are selected from the companies rep-
                           resented in the Morgan Stanley Capital International
                           Europe, Australia and Far East Index (the "EAFE In-
                           dex"). The allocation of Fund assets may shift from
                           time to time from countries that the Fund considers
                           overvalued to countries that it considers underval-
                           ued. Although the Fund seeks to equal or exceed the
                           return of the EAFE Index, the Fund may invest its as-
                           sets in proportions that differ from this index. The
                           Fund is not, therefore, an "index" fund, which typi-
                           cally holds securities in approximately the same pro-
                           portion as the index it attempts to replicate. The
                           Fund may at times invest more than 25% of its total
                           assets in a particular country.

RISK/RETURN SUMMARY AND FUND EXPENSES
 
PRINCIPAL RISKS
- --------------------------------------------------------------------------------
                         
Principal                Investing in the Equity Funds involves risks common
Investment Risks -       to any investment in securities. By itself, no Fund
  All Equity Funds       constitutes a balanced investment program.      
   
                         An investment in an Equity Fund is not a bank deposit
                         and is not insured or guaranteed by the Federal De-
                         posit Insurance Corporation or any other government
                         agency.     
 
                         The Equity Funds will invest principally in common
                         stocks, which have historically presented greater po-
                         tential for capital appreciation than fixed income
                         securities, but do not provide the same protection of
                         capital or assurance of income. There is no guarantee
                         that the Funds will meet their goals. When you sell
                         your shares in the Funds, they may be worth more or
                         less than you paid for them. It is possible to lose
                         money by investing in the Funds.
                            
                         Two principal risks of equity investing are market
                         risk and selection risk. Market risk means that the
                         stock market in general has ups and downs, which may
                         affect the performance of any individual stock. Se-
                         lection risk means that the particular stocks that
                         are selected for a Fund may underperform the market
                         or other funds with similar objectives.     
                         
Additional               Investment Style Risk
Principal                While stocks of smaller companies can provide greater 
Investment Risks         growth potential and potentially higher returns, they
                         carry higher risks than those of larger companies.
                         They may trade infrequently or in lower volumes, mak-
                         ing it difficult for a Fund to sell its shares at the
                         price it wants. Smaller companies may be more sensi-
                         tive to changes in the economy overall. Historically,
                         small company stocks have been more volatile than
                         those of larger companies. As a result, the Small
                         Company Growth Fund's net asset value may be subject
                         to rapid and substantial changes. The Growth and In-
                         come Fund is also subject to the same risk.     
   
                         Growth stocks offer strong revenue and earnings po-
                         tential and accompanying capital growth, with less
                         dividend income than value stocks. Growth stocks
                         present the risk that they may not perform as well as
                         other types of stocks, such as value stocks. Each of
                         the Equity Funds may invest in growth stocks.     
                            
                         Value stocks are those that appear to be underpriced
                         based upon valuation measures, such as lower price-
                         to-earnings ratios and price-to-book ratios. Value
                         stocks present the risk that they may not perform as
                         well as other types of stocks, such as growth stocks.
                         Each of the Equity Funds may invest in value stocks.
                                
                         Indexing is a strategy whereby the Index Equity Fund
                         attempts to weight its securities to match those of a
                         broadly-based securities index (the S&P 500) in an
                         attempt to approximate the index's performance. There
                         is the risk that the Index Equity Fund's investment
                         results may fail to match those of the S&P 500. There
                         is also the risk that if the S&P 500 does not perform
                         well, the investment results of the Index Equity Fund
                         may not be as favorable as other funds.

                         Investment in the International Growth Fund involves
                         additional risks not present in equity funds which
                         invest in shares of U.S. companies.     
 
                         Stocks of foreign companies are subject to special
                         risks:
                         . Currency risk means that fluctuations in foreign
                           exchange rates could affect the dollar value of a
                           Fund's securities. A decline in the value of a for-
                           eign currency versus the U.S. dollar reduces the
                           dollar value of securities denominated in that cur-
                           rency.
                            
                         . Compared to companies in the U.S., there is gener-
                           ally less publicly available information about for-
                           eign companies and there may be less government
                           oversight of foreign stock exchanges and the compa-
                           nies traded on them. There may also be less strin-
                           gent accounting, auditing and financial reporting
                           standards. In addition, foreign markets may have
                           lower trading volumes, resulting in stocks that may
                           be more difficult to sell and more volatile in
                           price. Investments in some foreign countries could
                           be subject to such factors as expropriation, con-
                           fiscation or difficulties enforcing contracts. All
                           of these factors can make foreign investments more
                           risky than U.S. investments.     
                            
                         . Furthermore, transaction fees may be higher for
                           foreign investments, due to higher brokerage com-
                           missions, fees on currency exchanges, and possible
                           imposition of dividend or interest withholding by
                           foreign governments. These may cause higher trans-
                           action costs which can result in lower returns or
                           decreased liquidity.

                         The International Growth Fund may invest more than
                         25% of its assets in a particular foreign country. A
                         concentration of investments in any one country could
                         expose the Fund to increased risk due to changes in
                         the economic or political environment within that
                         country.     
                                
                         A full discussion of all permissible investments can
                         be found in the Statement of Additional Information.

                         .willing to accept higher risks of investing in the
                          stock market in exchange for potentially higher long

 1  The Fund's Administrator has contractually agreed to waive a portion of
    the administration fee at least until December 31, 1999. As a result,
    Other Expenses would be 0.23%. You will be notified if the waiver is
    discontinued after that date.     
    
 2  The Fund's Investment Adviser and its Administrator have contractually
    agreed to waive a portion of their investment advisory and administration
    fees at least until December 31, 1999. As a result, Management Fees would
    be 0.25% for each class and Other Expenses would be 0.17% for each class.
    You will be notified if either of these waivers is discontinued after that
    date.     
    
 3  The Fund's Administrator has contractually agreed to waive a portion of
    the administration fee at least until December 31, 1999. As a result,
    Other Expenses are expected to be 0.39% for both classes. You will be
    notified if the waiver is discontinued after that date. Expenses for the
    Large Company Growth Fund are estimated based on expenses expected to be
    incurred in the current fiscal year.

 5  The Fund's Administrator has contractually agreed to waive a portion of
    the administration fee at least until December 31, 1999. As a result,
    Other Expenses would be 0.30% for each class. You will be notified if the
    waiver is discontinued after that date.     
    
 6 Investors should be aware that, due to the distribution fees, a long term
   shareowner in a Fund may pay over time more than the economic equivalent of
   the maximum front-end sales charge permitted under the rules of the
   National Association of Securities Dealers, Inc.     
          
Example: This Example is intended to help you compare the cost of investing in
the Funds with the cost of investing in other mutual funds. The Example as-
sumes:     
 .  $10,000 investment
 .  5% annual return
 .  redemption at the end of each period
    
 .  no changes in the Fund's operating expenses, except for the expiration of
    the current contractual fee waivers on December 31, 1999 (with the
    exception of the Large Company Growth Fund which assumes no contractual
    fee waivers)

INVESTMENT OBJECTIVE     Current income.    
                         
PRINCIPAL INVESTMENT     The Fund normally invests at least 65% of its total
STRATEGIES               assets in corporate and government debt securities.
                         The Fund is permitted to purchase U.S. Government ob-
                         ligations (those that are issued or guaranteed by the
                         U.S. Government or its agencies or instrumentalities)
                         and investment-grade corporate debt obligations
                         (those that are rated in one of the four highest cat-
                         egories by Nationally Recognized Statistical Rating
                         Organizations ("Rating Agencies"), or unrated securi-
                         ties of comparable quality. However, the Fund intends
                         to invest at least 65% of its total assets in U.S.
                         Government obligations and corporate debt obligations
                         that are rated in one of the three highest categories
                         by Rating Agencies (or unrated securities of compara-
                         ble quality). The Fund will maintain a dollar-
                         weighted average portfolio maturity between seven and
                         twenty years.     
 
                         While maturity and credit quality are the most impor-
                         tant investment factors, the Fund also considers the
                         following when making investment decisions:
                         .Current yield and yield to maturity.
                         .Potential for capital gain.
                            
                         While the Fund will not normally engage in frequent
                         trading of portfolio securities, it will make changes
                         in its investment portfolio from time to time as eco-
                         nomic conditions and market prices dictate based on
                         the Fund's investment objective. The Fund may also
                         sell a security if it falls below the minimum credit
                         quality required for purchase. If the Fund does buy
                         and sell securities frequently, there will be
                         increased transaction costs, which can negatively im-
                         pact Fund performance, and cause additional taxable
                         gains to shareholders.

RISK/RETURN SUMMARY AND FUND EXPENSES
 
KENT INTERMEDIATE BOND FUND
       
- --------------------------------------------------------------------------------
                         
INVESTMENT OBJECTIVE     Current income.     
   
PRINCIPAL INVESTMENT     The Fund normally invests at least 65% of its total
STRATEGIES               assets in corporate and government debt securities.
                         The Fund is permitted to purchase U.S. Government ob-
                         ligations (those that are issued or guaranteed by the
                         U.S. Government or its agencies or instrumentalities)
                         and investment-grade corporate debt obligations
                         (those that are rated in one of the four highest cat-
                         egories by Rating Agencies), or unrated securities of
                         comparable quality. The Fund will maintain a dollar-
                         weighted average portfolio maturity between three and
                         ten years.     
 
                         While maturity and credit quality are the most impor-
                         tant investment factors, the Fund also considers the
                         following when making investment decisions:
                         .Current yield and yield to maturity.
                         .Potential for capital gain.
                            
                         The Fund will actively buy and sell securities or
                         types of securities based on changing economic and
                         market conditions. The Fund may also sell a security
                         if it falls below the minimum credit quality required
                         for purchase. If the Fund buys and sells securities
                         frequently, there will be increased transaction
                         costs, which can negatively impact Fund performance,
                         and cause additional taxable gains to shareholders.

RISK/RETURN SUMMARY AND FUND EXPENSES
 
PRINCIPAL RISKS
- --------------------------------------------------------------------------------
        
   
Principal Investment     Investing in the Bond Funds involves the risks common
Risks -   All Bond Funds to any investment in securities. By itself, no Fund
                         constitutes a balanced investment program.     

                            
                         The Bond Funds will invest primarily in fixed income
                         securities, which provide income and a level of pro-
                         tection of capital, but present a lesser potential
                         for capital appreciation than equity securities.
                         There is no guarantee that the Funds will meet their
                         goals. When you sell your shares in the Funds, they
                         may be worth more or less than you paid for them. It
                         is possible to lose money by investing in the Funds.
                                
                         An investment in a Bond Fund is not a bank deposit
                         and is not insured or guaranteed by the Federal De-
                         posit Insurance Corporation or any other government
                         agency.     
                            
                         Two principal risks of fixed income (bond) investing
                         are market risk and selection risk. Market risk means
                         that the bond market in general has ups and downs,
                         which may affect the performance of any individual
                         fixed income security. Selection risk means that the
                         particular bonds that are selected for a Fund may
                         underperform the market or other funds with similar
                         objectives.     
                            
                         Interest Rate Risk     
                         ------------------
                         All bonds fluctuate in value as interest rates fluc-
                         tuate. Generally, as interest rates rise, the value
                         of a Fund's bond investments will decline, resulting
                         in capital losses to shareholders. In general, the
                         shorter the maturity, the lower the risk and the
                         lower the return.
                            
                         Credit Risk     
                         -----------
                            
                         The Bond Funds can acquire corporate bonds that carry
                         investment grade credit ratings, which are bonds
                         rated by a Rating Agency in the four highest rating
                         categories. Obligations rated in the fourth highest
                         rating category are considered to have speculative
                         characteristics. In addition, interest and principal
                         payments on these securities may not be insured or
                         guaranteed.     
                            
                         An issuer of fixed income securities could default on
                         its obligations to pay interest and repay principal.
                         A bond's credit rating could be downgraded. Both of
                         these events could cause a Fund to lose money.     
 
                         A full discussion of all permissible investments can
                         be found in the SAI.
                                                                            
       
    
Who May Want to Invest?  Consider investing in a Bond Fund if you are:
                         . seeking to add a monthly income component to your
                           portfolio
                         . seeking higher potential returns than those provided
                           by money market funds
                         . willing to accept the risks of price and dividend
                           fluctuations
 
                         These Funds will not be appropriate for anyone:

                         . seeking safety of principal

 1 The Fund's Administrator has contractually agreed to waive a portion of the
   administration fee at least until December 31, 1999. As a result, Other
   Expenses would be 0.23% for both classes. You will be notified if the
   waiver is discontinued after that date.     
    
 2 The Fund's Administrator has contractually agreed to waive a portion of the
   administration fee at least until December 31, 1999. As a result, Other
   Expenses would be 0.21% for both classes. You will be notified if the
   waiver is discontinued after that date.     
    
 3 The Fund's Distributor has contractually agreed to waive a portion of the
   Fund's 12b-1 fees for Investment Shares at least until December 31, 1999.
   In addition, the Fund's Administrator has contractually agreed to waive a
   portion of the administration fee at least until December 31, 1999.
   Accordingly, Distribution Fees would be 0.15% and Other Expenses would be
   0.26% for the Investment Shares and Other Expenses would be 0.26% for the
   Institutional Shares. You will be notified if either of these waivers is
   discontinued after that date.     
    
 4 Investors should be aware that, due to the distribution fees, a long term
   shareowner in a Fund may pay over time more than the economic equivalent of
   the maximum front-end sales charge permitted under the rules of the
   National Association of Securities Dealers, Inc.

the Funds with the cost of investing in other mutual funds. The Example as-
sumes:     
 . $10,000 investment
 . 5% annual return
 . redemption at the end of each period
 . no changes in the Fund's operating expenses, except for the expiration of
   the current contractual fee waivers on December 31, 1999

tions, your costs would be:

                         The Fund normally invests at least 80% of its net as-
PRINCIPAL INVESTMENT     sets in federally tax-exempt obligations. Federally
STRATEGIES               tax-exempt obligations consist of municipal bonds,
                         notes and commercial paper issued by states and other
                         local governments that are exempt from federal taxes.

                         ence item under the federal alternative minimum tax
                         will be considered taxable for purposes of this poli-
                         cy. The Fund maintains a dollar-weighted average
                         portfolio maturity between ten and twenty-five
                         years.

                         four highest rating categories by Rating Agencies or
                         unrated securities of comparable quality.     
 
                         While maturity and credit quality are the most impor-
                         tant investment factors, the Fund also considers the
                         following when making investment decisions:
                         . Current yield and yield to maturity.
                         . Potential for capital gain.
 
                         The Fund may also sell a security if it falls below
                         the minimum credit quality required for purchase.

RISK/RETURN SUMMARY AND FUND EXPENSES
 
PRINCIPAL RISKS
- --------------------------------------------------------------------------------
          
Principal                Investing in the Municipal Bond Funds involves the 
Investment Risks -       risks common to any investment in securities. By it-
All Municipal Bond       self, no Fund constitutes a balanced investment pro-
Funds                    gram.                                               
                            
                         The Municipal Bond Funds will invest primarily in
                         fixed income securities, which provide income and a
                         level of protection of capital, but present a lower
                         potential for capital appreciation than equity secu-
                         rities.     
                            
                         There is no guarantee that the Funds will meet their
                         goals. When you sell your shares in the Funds, they
                         may be worth more or less than you paid for them. It
                         is possible to lose money by investing in the Funds.
                                
                         An investment in a Municipal Bond Fund is not a bank
                         deposit and is not insured or guaranteed by the Fed-
                         eral Deposit Insurance Corporation or any other gov-
                         ernment agency.     
                            
                         Two principal risks of fixed income (bond) investing
                         are market risk and selection risk. Market risk means
                         that the bond market in general has ups and downs,
                         which may affect the performance of any individual
                         fixed income security. Selection risk means that the
                         particular bonds that are selected for a Fund may
                         underperform the market or other Funds with similar
                         objectives.     
                            
                         Interest rate risk     
                         All bonds fluctuate in value as interest rates fluc-
                         tuate. Generally, as interest rates rise, the value
                         of a Fund's bond investments will decline, resulting
                         in capital losses to shareholders. In general, the
                         shorter the maturity, the lower the risk and the
                         lower the return.
 
                         Credit risk
                            
                         The Bond Funds can acquire bonds that carry invest-
                         ment grade credit ratings, which are bonds rated by a
                         Rating Agency in the four highest rating categories.
                         Obligations rated in the fourth highest rating cate-
                         gory are considered to have speculative characteris-
                         tics. In addition, interest and principal payments on
                         these securities may not be insured or guaranteed.
                                
                         An issuer of fixed income securities could default on
                         its obligations to pay interest and repay principal.
                         A bond's credit rating could be downgraded. Both of
                         these events could cause a Fund to lose money.     
 
                         The types of obligations the Funds generally invest
                         in are listed below in descending order of credit
                         quality:
                         . general obligation bonds, which are backed by the
                           full faith, credit and taxing power of the munici-
                           pality
                         . revenue bonds, which are backed only by revenues
                           from a particular facility or revenue source
                         . private activity bonds issued by industrial devel-
                           opment authorities, which are used to finance pri-
                           vately owned facilities and which are backed by
                           private entities. The credit quality of these bonds
                           is a function of the creditworthiness of the pri-
                           vate entity.

Additional Principal     Concentration (State) Risk - Michigan Municipal Bond
Investment Risks         Fund     
                            
                         Due to the level of investment in municipal obliga-
                         tions issued by the State of Michigan and its politi-
                         cal subdivisions, the performance of the Fund will be
                         closely tied to the economic and political conditions
                         in the State of Michigan, and, therefore, an invest-
                         ment in the Fund may be riskier than an investment in
                         other types of municipal bond funds. The State's
                         economy is principally dependent upon manufacturing
                         (particularly automobiles, office equipment and other
                         durable goods), tourism and agriculture and histori-
                         cally has been highly cyclical. When a Fund's assets
                         are concentrated in obligations from revenues of sim-
                         ilar 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) related to such secu-
                         rities to a greater extent than if its assets were
                         not so concentrated.     
 
Who May Want to       
Invest?                  Consider investing in a Municipal Bond Fund if you
                         are:
                         .seeking to add a monthly income component to your
                          portfolio
                         .seeking higher potential returns than those provided
                          by money market funds
                         .willing to accept the risks of price and dividend
                          fluctuations
                         .seeking current income that is exempt from federal
                          income taxes (and, in the case of the Michigan
                          Municipal Bond Fund, current income that is exempt
                          from Michigan personal income taxes)
                         .willing to receive dividend distributions a portion
                          of which may be subject to the federal alternative
                          minimum tax
 
                         The Municipal Bond Funds are not appropriate for:
                         .tax-exempt institutions and certain retirement plans
                          that are unable to benefit from the receipt of tax-
                          exempt dividends

 1 The Fund's Administrator has contractually agreed to waive a portion of the
   administration fee at least until December 31, 1999. As a result, Other
   Expenses would be 0.26% for each class. You will be notified if the waiver
   is discontinued after that date.     
    
 2 The Fund's Administrator has contractually agreed to waive a portion of the
   administration fee at least until December 31, 1999. As a result, Other
   Expenses would be 0.23% for each class. You will be notified if the waiver
   is discontinued after that date.     
    
 3 The Fund's Distributor has contractually agreed to waive a portion of the
   Fund's 12b-1 fees for Investment Shares at least until December 31, 1999.
   In addition, the Fund's Administrator has contractually agreed to waive a
   portion of the administration fee at least until December 31, 1999.
   Accordingly, Distribution Fees would be 0.15% for the Investment Shares,
   and Other Expenses would be 0.24%, for the Investment Shares and
   Institutional Shares. You will be notified if either of these waivers is
   discontinued after that date.     
    
 4 Investors should be aware that, due to the distribution fees, a long term
   shareowner in a Fund may pay over time more than the economic equivalent of
   the maximum front-end sales charge permitted under the rules of the
   National Association of Securities Dealers, Inc.     
           
Example: This Example is intended to help you compare the cost of investing in
the Funds with the cost of investing in other mutual funds. The Example as-
sumes:     
 . $10,000 investment
 . 5% annual return
 . redemption at the end of each period
 . no changes in the Fund's operating expenses, except for the expiration of
   the current contractual fee waivers on December 31, 1999
   
Although your actual costs may be higher or lower, based upon these assump-
tions, your cost would be:

STRATEGIES                     ernment, bank and commercial obligations which
                               are considered to be of high credit quality and
                               easily sold in the secondary market. These se-
                               curities will have short term debt ratings in

                               security which matures in more than 397 days.
                               The Fund seeks to maintain a stable net asset
                               value of $1.00 per share, although there is no
                               guarantee that the net asset value will not
                               vary.

INVESTMENT OBJECTIVE     Current income that is exempt from federal income tax
                         and Michigan personal income tax.     
                     
PRINCIPAL INVESTMENT     The Fund normally invests at least 80% of its net as-
STRATEGIES               sets in federally tax-exempt obligations, which con-
                         sist of municipal bonds, notes and commercial paper
                         issued by states and local governments that are ex-
                         empt from federal taxes. The securities will have
                         short term debt ratings in the two highest rating
                         categories of at least two Rating Agencies or will be
                         unrated securities of comparable quality. Normally,
                         the Fund will invest at least 65% of its total assets
                         in municipal obligations issued by the State of Mich-
                         igan and its localities. The Fund's dollar-weighted
                         average portfolio maturity will not exceed 90 days.
                         The Fund will not purchase any security which matures
                         in more than 397 days. The Fund seeks to maintain a
                         stable net asset value of $1.00 per share, although
                         there is no guarantee that the net asset value will

RISK/RETURN SUMMARY AND FUND EXPENSES
 
PRINCIPAL RISKS
- --------------------------------------------------------------------------------
   
Principal Investment     Investing in the Money Market Funds involves the    
Risks -                  risks common to any investing in securities. By it-  
All Money Market Funds   self, no Fund constitutes a balanced investment pro- 
                         gram.                                                
                            
                         An investment in a Money Market Fund is not a bank
                         deposit and is not insured or guaranteed by the Fed-
                         eral Deposit Insurance Corporation or any other gov-
                         ernment agency.     
 
                         The Money Market Funds expect to maintain a net asset
                         value of $1.00 per share, but there is no assurance
                         that they will be able to do so on a continuous ba-
                         sis.
                            
                         There can be no assurance that the investment objec-
                         tives of each Money Market Fund will be achieved.
                                
                         Market Risk and Selection Risk     
                         The Funds' performance per share will change daily
                         based on many factors, including fluctuation in in-
                         terest rates, the quality of the instruments in each
                         Fund's investment portfolio, national and interna-
                         tional economic conditions and general market condi-
                         tions.
                            
                         Credit Risk     
                         The Money Market Funds may also be subject to credit
                         risks. Therefore, they could lose money if the issuer
                         of a security is unable to meet its financial obliga-
                         tions.
   
Additional Principal     Concentration (State) Risk - Michigan Municipal Money
Investment Risks         Market Fund     
                            
                         Due to the level of investment in municipal obliga-
                         tions issued by the State of Michigan and its local
                         governments, the performance of the Michigan Munici-
                         pal Money Market Fund will be closely tied to the
                         economic and political conditions in the State of
                         Michigan, and, therefore, an investment in the Fund
                         may be riskier than an investment in other types of
                         money market funds. The State's economy is princi-
                         pally dependent upon manufacturing (particularly au-
                         tomobiles, office equipment and other durable goods),
                         tourism and agriculture and historically has been
                         highly cyclical. The Michigan Municipal Money Market
                         Fund may also be subject to credit risks of municipal
                         issuers which may have historically experienced peri-
                         ods of financial difficulties. When a Fund's assets
                         are concentrated in obligations from revenues of sim-
                         ilar 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) related to such secu-
                         rities to a greater extent than if its assets were
                         not so concentrated.

ADDITIONAL INFORMATION
       
Investing for               
Defensive Purposes       When Lyon Street determines that market conditions
                         are appropriate, each of the Equity, Bond and Munici-
                         pal Bond Funds may, for temporary defensive purposes,
                         invest up to 100% of its assets in money market in-
                         struments. Each of the Bond and Municipal Bond Funds
                         may also shorten its dollar-weighted average maturity
                         below its normal range if such action is deemed ap-
                         propriate by Lyon Street for temporary defensive pur-
                         poses. In addition, the Michigan Municipal Bond Fund
                         may invest up to 100% of its total assets for tempo-
                         rary defensive purposes in municipal bonds the income
                         on which is exempt from federal income tax but not
                         exempt from Michigan personal income taxes. The Mich-
                         igan Municipal Money Market Fund may, for temporary
                         defensive purposes, hold uninvested cash reserves or
                         invest in short-term taxable money market obligations
                         in such proportions as, in the opinion of Lyon
                         Street, prevailing market or economic conditions war-
                         rant. If a Fund is investing defensively, it will not
                         be pursuing its investment objective.     
     
Year 2000 and the        Like other funds and business organizations around   
Kent Funds               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 proc-
                         ess and calculate date-related information for the
                         year 2000 and beyond. In addition, year 2000 issues
                         may adversely affect companies in which the Funds in-
                         vest where, for example, such companies incur sub-
                         stantial costs to address year 2000 issues or suffer
                         losses caused by the failure to adequately or timely
                         do so.     
                            
                         The Funds have been assured that the Adviser and
                         other service providers have developed and are imple-
                         menting clearly defined and documented plans intended
                         to minimize risks to services critical to the Funds'
                         operations associated with year 2000 issues. Internal
                         efforts include a commitment to dedicate adequate
                         staff and funding to identify and remedy year 2000
                         issues, and specific actions such as inventorying
                         software systems, determining inventory items that
                         may not function properly after December 31, 1999,
                         reprogramming or replacing such systems, and retest-
                         ing for year 2000 readiness. The Adviser and the
                         Funds' service providers are likewise seeking assur-
                         ances from their respective vendors and suppliers
                         that such entities are addressing any year 2000 is-
                         sues, and each provider intends to engage, where ap-
                         propriate, in private and/or industry interface test-
                         ing of systems for year 2000 readiness.     
                            
                         In the event that any systems upon which the Funds
                         are dependent are not year 2000 ready by December 31,
                         1999, administrative errors and account maintenance
                         failure would like occur.     
                            
                         While the ultimate costs or consequences of incom-
                         plete or untimely resolution of year 2000 issues by
                         the Adviser or the Funds' service providers cannot be
                         accurately assessed at this time, the Fund currently
                         has no reason to believe that the year 2000 plans of
                         the Adviser and the Funds' service providers will not
                         be completed by December 31, 1999, or that the antic-
                         ipated costs associated with full implementation of
                         their plans will have a material adverse impact on
                         either their business operations or financial condi-
                         tions or those of the Funds. The Funds and the Ad-
                         viser will continue to closely monitor developments
                         relating to this issue, including development by the
                         Adviser and the Funds' service providers of contin-
                         gency plans for providing back-up computer services
                         in the event of a systems failure or the inability of
                         any provider to achieve year 2000 readiness. Sepa-
                         rately, the Adviser will monitor potential investment
                         risk related to year 2000 issues.

                      Electronic vs. Wire Transfer
                      Wire transfers allow financial institutions to send funds
                      to each other, almost instantaneously. With an electronic
                      purchase or sale, the transaction is made through the
                      Automated Clearing House (ACH). ACH transactions usually
                      clear within 2 to 3 days, but may take up to 8 days.
                      There is generally no fee for ACH transactions.

You can make automatic investments in the Funds from your bank account, through
payroll deduction or from your federal employment, Social Security Supplemental
Security Income, or other regular government checks. Automatic investments can
be as little as $50, once you've invested the $1,000 minimum required to open
the account. Make sure you note:                                             
                                        
To invest regularly from your bank account:

Directed Dividend Option       
 (Investment Shares Only)      
                               
By selecting the appropriate box in the Account Application, you can elect to
receive your distributions in cash (check) or have distributions (capital gains
and dividends) reinvested in another Kent Fund. You must maintain the minimum
balance in each Fund into which you plan to reinvest dividends or the
reinvestment will be suspended and your dividends will be paid to you. The Funds
may modify or terminate this reinvestment option without notice. You can change
or terminate your participation in the reinvestment option at any time.
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
 
Dividends and Distributions
 
All dividends and distributions will be automatically reinvested unless you re-
quest otherwise. You can receive them in cash or by electronic funds transfer
to your bank account if you are not a participant in an IRA account or in a
tax-qualified plan. Dividends are higher for Institutional Shares than for In-
vestment Shares, because Institutional Shares have lower distribution expenses.
Capital gains are distributed at least annually.
 
Distributions are made on a per share basis regardless of how long you've owned
your shares. Therefore, if you invest shortly before the distribution date,
some of your investment will be returned to you in the form of a taxable
distribution.

by authorized shareholders. All telephone calls are recorded for your protec-
tion and you will be asked for information to verify your identity. Given these
precautions, unless you have specifically indicated on your application that
you do not want the telephone redemption feature, you may be responsible for
any fraudulent telephone orders.

When you have made your investment by check, you cannot redeem any portion of
it until the Transfer Agent is satisfied that the check has cleared (which may
require up to 10 business days). You can avoid this delay by purchasing shares
with a certified check.

Refusal of Redemption Request
   
The Funds may postpone payment for shares at times when the New York Stock Ex-
change is closed or under any emergency circumstances as determined by the U.S.
Securities and Exchange Commission. If you experience difficulty making a tele-
phone redemption during periods of drastic economic or market change, you can
send the Funds your request by regular or express mail. Follow the instructions
above under "Withdrawing Money From Your Fund Account--By Mail" in this sec-
tion.     
 
Redemption In Kind
   
The Funds reserve the right to make payment in securities rather than cash,
known as a "redemption in kind." This could occur under extraordinary circum-
stances, such as a very large redemption that could affect Fund operations (for
example, more than 1% of a Fund's net assets). If the Funds deem it advisable
for the benefit of all shareholders, a redemption in kind will consist of secu-
rities equal in market value to your shares. When you convert these securities
to cash, you will pay brokerage charges.     
 
Closing of Small Accounts
   
If your account falls below $1,000 ($100 for IRA Accounts) for Investment
Shares or $100,000 for Institutional Shares, a Fund may ask you to increase
your balance. If it is still below the minimum level after 60 days, the Fund
may close your account and send you the proceeds at the current NAV.     
 
Undeliverable Redemption Checks
   
For any shareholder who chooses to receive distributions in cash: If distribu-
tion checks (1) are returned and marked as "undeliverable" or (2) remain
uncashed for six months, your account will be changed automatically so that all
future distributions are reinvested in your account. Checks that remain
uncashed for six months will be canceled and the money reinvested in the Fund.
    
       
- --------------------------------------------------------------------------------
   
DISTRIBUTION AND SERVICE FEES     
   
12b-1 fees compensate the Distributor and other dealers and investment repre-
sentatives for services and expenses relating to the sale and distribution of
Investment Shares and for providing shareholder services to purchasers of In-
vestment Shares. 12b-1 fees are paid from Fund assets relating to Investment
Shares on an ongoing basis and will increase the cost of your investment. 12b-1
fees may cost you more than paying other types of sales charges.

See "General Policies on Selling your Shares" above for important information
about telephone transactions.     
 
To prevent disruption in the management of the Funds, due to market timing
strategies, exchange activity may be limited to five exchanges within a year,
or no more than three exchanges in a calendar quarter. Although unlikely, the
Funds may reject exchanges, or change or terminate rights to exchange shares.
- --------------------------------------------------------------------------------
 
Notes on Exchanges
The registration and tax identification numbers of the two accounts must be
identical. If you don't have an account with the new Fund, a new account will
be opened with the same features unless you write to tell us to change them.
 
The exchange privilege (including automatic exchanges) may be changed or elimi-
nated at any time.
 
Be sure to read the Prospectus carefully of any Fund into which you wish to ex-
change shares.
 
The exchange privilege is available only in states where shares of the new Fund
may be sold.
 
If shares of a Fund are purchased by check, those shares cannot be exchanged
until your check has been collected. This could take 10 days or more.
 
All exchanges are based on the relative net asset value next determined after
the exchange order is received by the Funds.
   
When Institutional Shares are distributed to the beneficial owners of trust ac-
counts, 401(k) plans, fiduciary or agency accounts, they can be in the form of
Investment Shares.     
 
                                                                              42

SHAREHOLDER INFORMATION
       
DIVIDENDS AND DISTRIBUTIONS
- --------------------------------------------------------------------------------
 
The Funds pay dividends to their shareholders from the Funds' respective net
investment income. The Funds distribute any net capital gains that have been
realized. Income dividends on each Fund are declared and paid monthly, except
for the Money Market Funds, which declare dividends daily and pay them monthly,
and the International Growth Fund, which pays dividends annually. Capital
gains, if any, for all Funds are distributed at least annually.
 
Dividends on each share class of the Funds are determined in the same manner
and are paid in the same amount. However, each share class bears all expenses
associated with that particular class. Since Investment Shares have higher dis-
tribution and service fees than Institutional Shares, the dividends paid to
shareholders owning Investment Shares will be lower than those paid to share-
holders owning Institutional Shares.
       
TAXATION
- --------------------------------------------------------------------------------
 
Federal Taxes
 
Each 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 rein-
vested in additional shares. Distributions attributable to the net capital gain
of a 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 tax-
able as ordinary income. You will be notified annually of the tax status of
distributions to you.
 
You should note that if you purchase shares just prior to a capital gain dis-
tribution, the purchase price will reflect the amount of the upcoming distribu-
tion, but you will be taxable on the entire amount of the distribution re-
ceived, even though, as an economic matter, the distribution simply constitutes
a return of capital. This is known as "buying into a dividend."
 
Except in the case of the Money Market Funds, you will recognize taxable gain
or loss on a sale, exchange or redemption of your shares, including an exchange
for shares of another Fund 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 dur-
ing 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 on the shares.
 
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-quali-
fied plan) will not be currently taxable.
 
The International Growth Fund. It is expected that the International Growth
Fund will be subject to foreign withholding taxes with respect to dividends or
interest received from sources in foreign countries. The International Growth
Fund may make an election to treat a proportionate amount of such taxes as con-
stituting a distribution to each shareholder, which would allow each share-
holder either (1) to credit such proportionate amount of taxes against U.S.
federal income tax liability or (2) to take such amount as an itemized deduc-
tion.
   
The Michigan Municipal Money Market Fund and the Municipal Bond Funds. It is
expected that the Michigan Municipal Money Market Fund and the Municipal Bond
Funds will distribute dividends derived from interest earned on tax-exempt se-
curities, and these "exempt interest dividends" will be exempt income for
shareholders for federal income tax purposes. However, distributions, if any,
derived from net capital gains will generally be taxable to you as capital
gains. The Municipal Bond Funds may pay such capital gains distributions from
time to time. Dividends, if any, derived from taxable interest income will be
taxable to you as ordinary income.

TAXATION     
- --------------------------------------------------------------------------------
 
Interest on indebtedness incurred by a shareholder to purchase or carry shares
of the Michigan Municipal Money Market Fund and the Municipal Bond Funds gener-
ally will not be deductible for federal income tax purposes.
 
You should note that a portion of the exempt-interest dividends paid by the
Michigan Municipal Money Market Fund and the Municipal Bond Funds may consti-
tute 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 tax-
es.
 
If you receive an exempt-interest dividend with respect to any share and the
share is held by you for six months or less, any loss on the sale or exchange
of the share will be disallowed to the extent of such dividend amount.
 
The foregoing is only a summary of certain tax considerations under current
law, which may be subject to change in the future. You should consult your tax
adviser for further information regarding federal, state, local and/or foreign
tax consequences relevant to your specific situation.
 
State and Local Taxes
 
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 each
Fund's distributions, if any, that are attributable to interest on federal se-
curities or interest on securities of the particular state or an agency there-
of.
 
Because the Michigan Municipal Bond Fund and the Michigan Municipal Money
Market Fund intend to invest substantially all of their assets in tax-exempt
obligations of the State of Michigan or its political subdivisions,
shareholders who are subject to Michigan state income tax will generally not be
subject to tax on dividends paid by these Funds to the extent that the
dividends are attributable to interest income of these Funds. Shareholders
should consult their tax advisers regarding the tax status of distributions in
their state and locality.
 
                                                                              44

FINANCIAL HIGHLIGHTS
       
          
The financial highlights tables are intended to help you understand the Funds'
financial performance for the past 5 years or, if shorter, the period of each
Fund's operations. Certain information reflects financial results for a single
Fund share. The total returns in the tables represent the rate that an investor
would have earned or lost on an investment in a Fund (assuming reinvestment of
all dividends and distributions). This information has been audited by KPMG
LLP, whose report, along with the Funds' financial statements, are included in
the Funds' annual report, which is available upon request.
